Description

APARATO PARA SOPORTAR Y CAMBIAR LA POSICIÓN DE UNA PANTALLA PLANA, DE MESA DE TRABAJO A PANTALLA PARA EXPOSICIÓN.  APPARATUS TO SUPPORT AND CHANGE THE POSITION OF A FLAT SCREEN, FROM WORK TABLE TO DISPLAY FOR EXHIBITION.
DESCRIPCIÓN DE LA INVENCIÓN Campo técnico de la invención DESCRIPTION OF THE INVENTION Technical Field of the Invention
La presente invención se refiere a un aparato para soportar una pantalla plana o display compatible con un equipo de cómputo y convertirla en una pantalla sensible al tacto o pantalla "Multitouch" que puede ser utilizada como mesa de trabajo o pantalla vertical. El aparato cuenta con un mecanismo que permite el desplazamiento de una pantalla plana de posición vertical a horizontal y viceversa, utilizando un solo actuador para elevar o descender la pantalla y al mismo tiempo cambiar la posición vertical de la pantalla a posición horizontal mediante movimientos simultáneos, manteniendo en todo momento el centro de gravedad, evitando que el conjunto vuelque. Antecedentes de la Invención: The present invention relates to an apparatus for supporting a flat screen or display compatible with computer equipment and converting it into a touch-sensitive screen or "Multitouch" screen that can be used as a worktable or vertical screen. The device has a mechanism that allows the movement of a flat screen from vertical to horizontal position and vice versa, using a single actuator to raise or lower the screen and at the same time change the vertical position of the screen to horizontal position by simultaneous movements, maintaining the center of gravity at all times, preventing the assembly from tipping over. Background of the Invention:
La solicitud de patente de los Estados Unidos US 2009095868 A1 publicada el 16 de abril de 2009, se refiere a un arreglo para soporte de un dispositivo de presentación, como por ejemplo un dispositivo de presentación tal como una pantalla plana en conexión con una superficie de trabajo en forma de un escritorio. La pantalla se encuentra libremente acoplada sobre el dispositivo de soporte en forma de una pantalla plana. Todos estos dispositivos pueden ser desplazados verticalmente porque se encuentran a su vez montados en un soporte que consiste de una columna vertical extensible que puede encontrarse dispuesta en un arreglo telescópico. La invención considera aspectos ergonómicos asociados a la posición de un observador que trabaja sobre la mesa y a su vez, debe observar la pantalla. Un cambio de posición del observador, puede alterar su percepción de la imagen que se proyecta en la pantalla, pero es impensable que el observador pueda mantener siempre una misma postura, por lo tanto, la altura de la mesa de trabajo es variable, haciendo que al mismo tiempo la inclinación de la pantalla se ajuste al foco de un observador. Así mismo, diferentes usuarios tienen diferente estatura y por lo tanto, la mesa de trabajo así como la pantalla deben poder ajustarse a el foco de cada observador. US patent application US 2009095868 A1 published on April 16, 2009, refers to an arrangement for supporting a presentation device, such as a presentation device such as a flat screen in connection with a surface of I work in the form of a desk. The screen is freely coupled on the support device in the form of a flat screen. All these devices can be displaced vertically because they are in turn mounted on a support consisting of an extendable vertical column that can be arranged in a telescopic arrangement. The invention considers ergonomic aspects associated with the position of an observer working on the table and, in turn, must observe the screen. A change of position of the observer, can alter his perception of the image that is projected on the screen, but it is unthinkable that the observer can always maintain the same posture, therefore, the height of the worktable is variable, causing at the same time the inclination of the screen fits the focus of an observer. Likewise, different users have different stature and therefore, the worktable as well as the screen must be able to adjust to the focus of each observer.
La invención considera dos superficies y no solo una, además de que considera un ángulo de inclinación limitado menor a 90 grados y no permite que el usuario pueda trabajar con la pantalla completamente en posición horizontal, ya que el conjunto de la mesa estorbaría su desempeño y alejaría la imagen del observador. La cantidad de elementos de dicha invención es excesiva para la función que realiza y hace necesaria la incorporación de una base que se extiende más allá de las dimensiones de la mesa de trabajo y del conjunto formado por la mesa de trabajo y la pantalla plana. El exceso de dimensiones es necesario para compensar que la mesa no cuenta con un centro de gravedad que permita su equilibrio y por lo tanto, una base que se extiende más allá del conjunto contrarresta los momentos provocados por el peso de la pantalla colocada fuera del eje de la columna de soporte. The invention considers two surfaces and not just one, in addition to considering a limited angle of inclination less than 90 degrees and does not allow the user to work with the screen completely in a horizontal position, since the whole table would hinder its performance and I would zoom out from the observer. The amount of elements of said invention is excessive for the function it performs and makes it necessary to incorporate a base that extends beyond the dimensions of the work table and the assembly formed by the work table and the flat screen. The excess of dimensions is necessary to compensate that the table does not have a center of gravity that allows its balance and therefore, a base that extends beyond the set counteracts the moments caused by the weight of the screen placed outside the axis of the support column.

Está invención, si bien permite alternar la posición horizontal y vertical de la pantalla, requiere de una base lo suficientemente amplia para mantener la estabilidad de la mesa mientras se realiza el cambio de posición. Si bien esta invención trabaja con un solo actuador y permite alternar la mesa que sostiene la pantalla entre una posición vertical y horizontal, no permite la elevación de la pantalla debido a que la mesa está sujetada en la parte inferior y por dentro del gabinete que soporta la mesa a una articulación que permite un movimiento rotacional sobre un punto fijo, pero no un movimiento de traslación, quedando la pantalla a una misma altura. This invention, although it allows to alternate the horizontal and vertical position of the screen, requires a base wide enough to maintain the stability of the table while the change of position is made. Although this invention works with a single actuator and allows to alternate the table that holds the screen between a vertical and horizontal position, it does not allow the elevation of the screen because the table is held at the bottom and inside the cabinet that supports the table to a joint that allows a rotational movement on a fixed point, but not a translation movement, leaving the screen at the same height.

Como puede apreciarse, ninguna de las invenciones previas referidas en el estado del arte permite el cambio en la inclinación del ensamble de la mesa con la pantalla y el cambio en la altura de la mesa. United States patent application US / 2010/0085493 dated April 8, 2010, refers to the assembly of a cabinet with a panel for a flat television, a support device and a force or motor device . An open slot is defined on the top face of the frame and allows the television assembly to pass through the slot. The television assembly is mounted on a support device and disposed within the frame. The support device is actuated by an actuator device to move up or down. When the support device is brought to its highest position, the TV assembly is exposed outside the surface of the frame. When the support device is brought to the lowest position, the TV assembly is received entirely within the frame, the upper end of the TV assembly is coplanar with the upper face of the frame, and the cabinet can be used as a regular cabinet or as a table.

Un invento cercano a la presente invención es el montaje de la Touchtable TT45, en donde la pantalla es montada sobre un pedestal que permite alternar la posición de la pantalla entre la posición vertical y horizontal, además de puntos intermedios. Un mecanismo eléctrico se encarga del ajuste de altura y cuenta con ruedas para facilitar su movilidad. La Touchtable TT45 tiene un soporte central que se encuentra colocado sobre una base horizontal en forma de "H", en donde en los extremos de los brazos de la "H" cuentan con ruedas para su desplazamiento. Esta invención ha sido desarrollada para soportar pantallas de 46 pulgadas y por lo tanto, requiere que los brazos de la "H" sobresalgan por enfrente de la pantalla manteniendo así el equilibrio cuando la pantalla cambia de posición. Adicionalmente, el soporte vertical está colocado en una posición intermedia con respecto a la distancia que existe entre los brazos de la "H", pero se encuentra en una posición excéntrica con relación a la longitud de los brazos de la "H", quedando la pantalla suspendida sobre el punto medio de los brazos de la "H" y travesaño que une los brazos de la "H" se encuentra colocado atrás del punto intermedio de los brazos de la Ή", de tal forma que se mantiene el centro de gravedad. Esta configuración provoca un problema cuando la pantalla se encuentra en posición vertical al ser la base un riesgo potencial con el cual pueden tropezar los usuarios y volcar la pantalla. Se intuye que por estos motivos la máxima altura para la pantalla Touchtable TT45 en el borde superior de la pantalla cuando se encuentra en una posición vertical es de 58 pulgadas (1.47 m.) y el borde inferior de la pantalla queda a una altura 32 pulgadas (81.28 cm) con respecto al suelo, siendo una altura poco útil cuando se realiza una presentación, por lo cual el equipo denominado Touchtable TT45 pierde funcionalidad como pantalla táctil vertical, ya que el presentador tendría que inclinarse para tocar la sección inferior de la pantalla. An invention close to the present invention is the assembly of the Touchtable TT45, where the screen is mounted on a pedestal that allows to alternate the position of the screen between the vertical and horizontal position, in addition to intermediate points. An electric mechanism is responsible for height adjustment and has wheels for easy mobility. The Touchtable TT45 has a central support that is placed on a horizontal base in the form of "H", where at the ends of the arms of the "H" have wheels for movement. This invention has been developed to support 46-inch screens and therefore requires that the "H" arms protrude in front of the screen thus maintaining balance when the screen changes position. Additionally, the vertical support is placed in an intermediate position with respect to the distance between the arms of the "H", but is in an eccentric position in relation to the length of the arms of the "H", leaving the screen suspended on the midpoint of the arms of the "H" and crossbar that joins the arms of the "H" is located behind the intermediate point of the arms of the Ή ", so that the center of gravity is maintained This configuration causes a problem when the screen is in an upright position as the base is a potential risk that users may stumble and flip the screen.It is intuited that for these reasons the maximum height for the Touchtable TT45 screen on the edge The upper part of the screen when it is in an upright position is 58 inches (1.47 m.) and the bottom edge of the screen is 32 inches (81.28 cm) high from the ground, being a little high useful when a presentation is made, so the device called Touchtable TT45 loses functionality as a vertical touch screen, since the presenter would have to lean to touch the lower section of the screen.
Adicionalmente, la pantalla cuenta con dos mecanismos para realizar los movimientos de elevación e inclinación, pudiendo ser estos movimientos independientes, lo cual requiere de una sincronización cuando la pantalla desciende para colocarse en posición horizontal, de lo contrario el centro de gravedad se perdería y ocurriría una volcadura. Las especificaciones para la pantalla del sistema TT45 son de una pantalla de 46 pulgadas en diagonal y no se menciona que se pueda colocar una pantalla de diferentes dimensiones. Additionally, the screen has two mechanisms to perform the movements of elevation and inclination, being able to be these movements independent, which requires a synchronization when the screen descends to be placed horizontally, otherwise the center of gravity would be lost and a rollover would occur. The specifications for the TT45 system screen are a 46-inch diagonal screen and it is not mentioned that a screen of different dimensions can be placed.
La solicitud internacional con número de publicación WO/2013/105842 es un antecesor también creado por nosotros. Esta invención fue desarrollada con propósito de poder cambiar la posición horizontal de una pantalla a una posición vertical; para mantener el centro de gravedad se optó por que el poste de levantamiento, mismo que se encarga de soportar el peso de la pantalla y las barras guía se encontraran desalineadas formando un arreglo triangular, de esta forma se lograba mayor estabilidad, consecuencia de este mecanismo es que el poste de levantamiento requería en su extremo superior de una proyección perpendicular para sujetar la base de la pantalla que estuviera alineada con las barras guía. Otro inconveniente de esa invención es que hacía necesario un par de brazos que se proyectaban horizontalmente hacia la parte posterior de la placa horizontal, mientras que las barras de giro debían tener una mayor longitud. Para eliminar estos inconvenientes, la nueva invención cuenta con un actuador eléctrico que elimina a todo el conjunto motriz de la invención referida arriba, además de que se incorpora en la parte posterior del soporte de pantalla un mecanismo de acoplamiento y giro semejante a una bisagra en donde tanto las barras guía como el actuador central se acoplan para un movimiento coordinado, por lo que consideramos que la presente invención supera ampliamente a su antecesor, siendo la solución novedosa e inventiva. The international application with publication number WO / 2013/105842 is an ancestor also created by us. This invention was developed with the purpose of being able to change the horizontal position of a screen to a vertical position; in order to maintain the center of gravity, it was decided that the lifting post, which is responsible for supporting the weight of the screen and the guide bars are misaligned forming a triangular arrangement, thus achieving greater stability, as a result of this mechanism is that the lifting post required at its upper end a perpendicular projection to hold the base of the screen that was aligned with the guide bars. Another drawback of that invention is that it required a pair of arms that projected horizontally towards the back of the horizontal plate, while the pivot bars had to be longer. To eliminate these drawbacks, the new invention has an electric actuator that eliminates the entire drive assembly of the invention referred to above, in addition to which a hinge-like coupling and rotation mechanism is incorporated in the back of the screen support in where both the guide rods and the central actuator are coupled for a coordinated movement, so we consider that the present invention far exceeds its predecessor, being the novel and inventive solution.

Descripción detallada de la invención. Como previamente se planteó, el problema con los soportes móviles para pantallas es la capacidad de mantener el centro de gravedad y la estabilidad en el momento en que se eleva la pantalla o cambia de inclinación, utilizando un solo actuador para realizar ambos movimientos (elevación e inclinación) al mismo tiempo, además de lograr una mayor altura para realizar presentaciones; y contar además con un soporte que permite retirar la pantalla del aparato y colocarla en un soporte de pared. La solución más cercana que se había presentado consideraba una base de grandes dimensiones para mantener el centro de gravedad y la estabilidad durante el funcionamiento del aparato, haciendo al aparato un tanto estorboso; adicionalmente, un mecanismo pesado y complejo a base de poleas y un motor eléctrico, se encargaba de elevar la pantalla desde su posición inicial, siendo el peso del mecanismo una contribución para mantener el centro de gravedad. Detailed description of the invention. As previously stated, the problem with mobile display stands is the ability to maintain the center of gravity and stability at the time the screen rises or changes inclination, using a single actuator to perform both movements (elevation and inclination) to same time, in addition to achieving a greater height to make presentations; and also have a support that allows the screen to be removed from the device and placed on a wall bracket. The closest solution that had been presented considered a large base to maintain the center of gravity and stability during the operation of the apparatus, making the apparatus somewhat cumbersome; additionally, a heavy and complex pulley-based mechanism and an electric motor, was responsible for raising the screen from its initial position, the weight of the mechanism being a contribution to maintain the center of gravity.
Para solucionar el problema planteado, se diseñó un mecanismo que eleva la pantalla verticalmente y que al mismo tiempo va cambiando la inclinación de la pantalla desde 0 a 90 grados, manteniendo el centro de gravedad de la pantalla lo más cercano al eje vertical donde se localiza el centro de gravedad de la base para hacer del producto un sistema estable sin la necesidad de una base inferior de grandes dimensiones. To solve the problem, a mechanism was designed that elevates the screen vertically and at the same time changes the inclination of the screen from 0 to 90 degrees, keeping the center of gravity of the screen as close to the vertical axis where it is located the center of gravity of the base to make the product a stable system without the need for a large base base.

Essential element of the present invention (Figure 5) is the hinge type coupling (11) which is formed by three elements to be defined; a fixed element (12) and a mobile element (13), wherein the fixed element (12) is formed by a horizontal bar of rectangular profile that joins the actuator (14) and the guide bars (10), has two notches (20) of rectangular section to allow the coupling and rotation of the mobile element (13) and three heads in the form of a horizontal cylinder or cylindrical heads (21) spaced equally, two laterally and a central unit, which must be inserted interspersed between the central projections (22) and lateral projections (23) of the mobile element (13), wherein the cylindrical heads (21) have a horizontal perforation to the center (not shown); a mobile element (13) formed by a base of the mobile element (24), two central projections (22) perpendicular to the base of the mobile element (24) that must coincide in the assembly with the notches (20) of rectangular section of the element fixed (12) of the hinge type coupling (11) and two perpendicular lateral projections (23) that fit the outer faces of the cylindrical heads (21) located on the sides, where the central projections (22) and the lateral projections (23) are rounded at their ends and feature a horizontal perforation to the center (not shown) to allow the passage of an assembly element; and an assembly element (16) which can be a screw or bolt that crosses both the cylindrical heads (21) of the fixed element (12), as the central projections (22) and lateral projections (24) of the mobile element (13) , thus forming a hinge type coupling (11).
El marco de soporte (8) (figura 5) está formada por dos soportes laterales (9) que resguardan a las barras guía (10) y que en su extremo inferior se encuentran unidos a la base horizontal (4) y en su extremo superior se unen a una placa horizontal (15) que tiene forma rectangular, formando así un marco cerrado; la placa horizontal (15) en su mitad anterior cuenta con tres orificios circulares para el paso de las barras guía (10) y de la barra del actuador (14), mientras que en su mitad posterior cuenta con dos articulaciones posteriores (17) para sujetar a los brazos de giro (18) que en sus extremos posteriores se sujetan en forma articulada a la placa horizontal (15) y en los extremos anteriores se sujetan de igual forma a la estructura intermedia (7) mediante puntos de articulación anteriores (19). En el interior de los soportes laterales (9) se encuentran las barras guía (10) a los costados del aparato, que son elementos extensibles verticalmente y corren dentro de baleros de deslizamiento lineal de rodillos o bujes de Nylamid u otro material que tenga iguales o semejantes propiedades mecánicas que permita su uso, cuyo único movimiento es el desplazamiento vertical; las barras guía (10), solamente sirven como guías de levantamiento y están diseñadas y calculadas para proporcionar total rigidez de la pantalla ante las fuerzas cortantes y de torsión a las que es sometido el mecanismo durante su posicionamiento de mesa de trabajo a pantalla de presentación, es decir, de posición horizontal a posición vertical y viceversa. Las barras guía (10) en su extremo superior se encuentran unidas al acoplamiento de tipo bisagra (1 1) quedando a los costados del actuador (14). Las barras guía (10) y el actuador (14) se encuentran unidos al elemento fijo (12) del acoplamiento tipo bisagra (11) por debajo de las cabezas cilindricas (21 ). Unido en su extremo inferior a la base horizontal (4) y en medio de los dos soportes laterales (9) se encuentra el actuador (14) que es un mecanismo de tipo pistón eléctrico que se encarga de soportar en todo momento el peso de la pantalla plana (2) y demás accesorios, además de elevar o descender la pantalla plana (2). El actuador eléctrico (14) o pistón al igual que las barras guía (10), atraviesan la placa horizontal (15) y en su extremo superior están unidos con el elemento fijo (12) de la acoplamiento de tipo bisagra (1 1), quedando el actuador (14) al centro del acoplamiento tipo bisagra (11) y las barras guía (10) a los lados. The support frame (8) (figure 5) is formed by two lateral supports (9) that protect the guide bars (10) and that at its lower end are attached to the horizontal base (4) and at its upper end they are joined to a horizontal plate (15) that has a rectangular shape, thus forming a closed frame; The horizontal plate (15) in its front half has three circular holes for the passage of the guide bars (10) and the actuator bar (14), while in its rear half it has two rear joints (17) for fasten to the swing arms (18) that at their rear ends are attached in an articulated manner to the horizontal plate (15) and at the front ends are similarly attached to the intermediate structure (7) by means of anterior articulation points (19 ). Inside the lateral supports (9) are the guide rods (10) on the sides of the apparatus, which are vertically extensible elements and run inside linear sliding bearings of Nylamid rollers or bushings or other material having the same or similar mechanical properties that allow its use, whose only movement is vertical displacement; the guide bars (10), only serve as lifting guides and are designed and calculated to provide total rigidity of the screen against the shear and torsional forces to which the mechanism is subjected during its positioning from worktable to presentation screen , that is, from horizontal position to vertical position and vice versa. The guide rods (10) at their upper end are connected to the hinge type coupling (1 1) being at the sides of the actuator (14). The guide bars (10) and the actuator (14) are connected to the fixed element (12) of the hinge type coupling (11) below the cylindrical heads (21). Attached at its lower end to the horizontal base (4) and in the middle of the two lateral supports (9) is the actuator (14) which is an electric piston-type mechanism that is responsible for supporting the weight of the flat screen (2) and other accessories, in addition to raising or lowering the flat screen (2). The electric actuator (14) or piston, like the guide rods (10), crosses the horizontal plate (15) and at its upper end are connected to the fixed element (12) of the hinge type coupling (1 1), the actuator (14) being at the center of the hinge type coupling (11) and the guide bars (10) on the sides.
La estructura intermedia (7) que sujeta a la pantalla plana (2) está unida al elemento móvil (13) de la acoplamiento tipo bisagra (11) y el elemento móvil (13) se une mediante un elemento de ensamble que puede ser perno o tornillo (16) con el elemento fijo (12), de tal forma que la estructura intermedia (7) de la pantalla plana puede girar desde una posición horizontal (0 grados) hasta una posición vertical (90 grados). La ventaja de !a configuración que se pretende proteger reside en que se ha logrado mantener en todo momento el centro de gravedad aún cuando la base horizontal (4) y el gabinete (3) se han reducido en sus dimensiones, para ello, fue necesario alinear las barras guía (10) con el actuador (14) y acoplarlos de forma articulada a la estructura intermedia (7) mediante una acoplamiento de tipo bisagra ( 1) y reducir el tamaño de la placa horizontal (15). La alineación del actuador (14) con las barras de guía (10) permite angostar el cuerpo de la base horizontal (4) manteniendo por detrás del actuador (14) las articulaciones posteriores (17) de las barras de giro (18). The intermediate structure (7) that attaches to the flat screen (2) is connected to the mobile element (13) of the hinge type coupling (11) and the mobile element (13) is joined by an assembly element that can be bolted or screw (16) with the fixed element (12), so that the intermediate structure (7) of the flat screen can rotate from a horizontal position (0 degrees) to a vertical position (90 degrees). The advantage of the configuration to be protected is that the center of gravity has been maintained at all times even when the horizontal base (4) and the cabinet (3) have been reduced in size, to it was necessary to align the guide bars (10) with the actuator (14) and articulate them to the intermediate structure (7) by means of a hinge type coupling (1) and reduce the size of the horizontal plate (15). The alignment of the actuator (14) with the guide rods (10) makes it possible to narrow the body of the horizontal base (4) by keeping behind the actuator (14) the rear joints (17) of the rotating rods (18).
Adicionalmente, se ha modificado la forma en que se acopla la pantalla al mecanismo. De la pantalla sobresalen dos placas rectangulares (25) que cuentan con cuatro perforaciones que cuentan en cada perforación con cuerda interior que les permiten acoplarse con un soporte universal para montaje en pared de pantallas planas. En este caso, las cuatro perforaciones con cuerda interior sirven para unir la pantalla con la estructura intermedia (7). La estructura intermedia (7) a su vez se sujeta con el soporte del elemento móvil (13) mediante cinco tornillos que se sujetan a igual número de perforaciones con cuerda interior en dicho elemento móvil (13). La estructura intermedia (7) tiene forma de Ή" formada por dos brazos paralelos (26) y una placa transversal (27) angosta que sirve de unión a los brazos paralelos (26). En cada brazo paralelo (26) se cuenta con una ranura (28) longitudinal en donde se introducen las placas rectangulares (25) de los soportes de principales de la pantalla y que por su forma permite que el peso se recargue sobre el mismo soporte y no en los cuatro tornillos que mantienen unida a la pantalla plana (2), por lo que los cuatro tornillos solamente son elementos de unión y no reciben esfuerzo cortante. La forma de rectángulo que tienen las placas rectangulares (25) y las ranuras longitudinales (28) debe ser coincidente y puede ser reemplazada por cualquier forma que proporcione el mismo soporte o incremente la superficie de soporte, pues la forma que nosotros utilizamos fue pensando en la disminución de operaciones de manufactura y gasto de material. Lista de componentes principales del sistema Additionally, the way in which the screen is coupled to the mechanism has been modified. From the screen stand out two rectangular plates (25) that have four perforations that feature in each perforation with inner rope that allow them to be coupled with a universal support for wall mounting of flat screens. In this case, the four perforations with inner rope serve to join the screen with the intermediate structure (7). The intermediate structure (7) in turn is fastened with the support of the mobile element (13) by five screws that are fastened to the same number of perforations with inner rope in said mobile element (13). The intermediate structure (7) has a Ή "shape formed by two parallel arms (26) and a narrow transverse plate (27) that serves as a connection to the parallel arms (26). In each parallel arm (26) there is a longitudinal groove (28) where the rectangular plates (25) of the main screen supports are inserted and that by its shape allows the weight to be reloaded on the same support and not on the four screws that hold the screen together flat (2), so the four screws are only connecting elements and do not receive shear stress.The rectangle shape of the rectangular plates (25) and the longitudinal grooves (28) must be coincident and can be replaced by any form that provides the same support or increases the surface of support, because the form that we used was thinking about the reduction of operations of manufacture and expense of material.
