A frame for sewing upper pillows on covering shells for mattresses, which comprises four perimetric walls; each wall is perpendicular to the two contiguous walls and comprises at least one laminar portion that constitutes a resting surface, the laminar portion being co-planar with a lower edge of the respective wall, at least one of such walls comprising at least one locking element for at least one component, selected from between an upper pillow and a covering shell, arranged on a respective laminar portion.
Description
- This application is related to and claims the benefit of Italian Patent Application Number B02013A000099 filed on 08 Mar. 2013, the contents of which are herein incorporated by reference in their entirety.
- The present invention relates to a frame for sewing upper pillows on covering shells for mattresses, a respective machine for sewing upper pillows on covering shells for mattresses, and a method of sewing upper pillows on covering shells for mattresses.
- Mattresses have undergone considerable advances in recent years: such advances have concerned the materials that constitute them, their structure and the presence/absence of specific components.
- Recently the adoption is increasingly frequent of technical solutions that involve a true mattress, parallelepiped in shape, which is contained inside two substantially mirror-symmetrical shells, which are mutually interconnected along respective facing and proximate edges.
- The coupling can be fixed (for example by way of stitch lines and/or edging) or detachable (for example using zip fasteners and/or strips of Velcro® and the like).
- In this type of mattress, recently we have witnessed the spread (and to the great appreciation by customers) of mattresses that are provided with an accessory component called a “pillow top”.
- This embodiment involves the arrangement of a slim pillow on the top of the mattress, so as to define a soft layer at the surface upon which the users lie.
- The thickness of this pillow is, generally, a few centimeters (starting from a minimum of approximately one centimeter up to five or more centimeters); despite the scant thickness, the interposition of this pillow between the mattress itself and the sheet offers the user a sensation of great comfort.
- It is evident that this implementation solution requires an increase in the number of steps of working on the semi-finished product that will constitute the upper shell of the mattress.
- In order to ensure a sufficient qualitative standard of the finished product, placing the pillow top on the respective shell and the corresponding mutual coupling are operations that are generally performed manually by specialist craftworkers.
- This therefore determines a considerable increase in the costs of mattresses provided with these pillow tops, which relates to the cost of the labor necessary for their production.
- Furthermore the production times are rather long, with consequent production limits that are linked to the need for manual intervention on each one of the mattresses: an increase in productivity is necessarily associated with the hiring of additional specialist craftworkers, who are able to carry out the necessary work.
- The artisan nature of the work, furthermore, does not permit a standardization of the product within narrow margins, without providing for a high number of production discards.
- The principal aim of the present invention is to solve the above mentioned drawbacks, by providing a frame for sewing upper pillows on covering shells for mattresses which makes it possible to juxtapose the pillow top and the respective covering shell in a simplified manner, thus facilitating their subsequent coupling.
- Within this aim, the invention provides a machine for sewing upper pillows on covering shells for mattresses, which is entirely automated.
- The invention further provides a machine for sewing upper pillows on covering shells for mattresses which has a high rate of productivity.
- The invention further provides a machine for sewing upper pillows on covering shells for mattresses which makes it possible to obtain a constant qualitative standard of the semi-finished products that it produces.
- The invention further provides a method of sewing upper pillows on covering shells for mattresses which is simplified and which requires a minimal application of labor.
- The invention further provides a frame for sewing upper pillows on covering shells for mattresses, a machine for sewing upper pillows on covering shells for mattresses, and a method of sewing upper pillows on covering shells for mattresses, which are low cost, are easily and practically implemented, and are practical and safe in use.
- These aims are achieved by a frame for sewing upper pillows on covering shells for mattresses, characterized in that it comprises four perimetric walls, each wall being perpendicular to the two contiguous walls and comprising at least one laminar portion that constitutes a resting surface, said laminar portion being co-planar with a lower edge of said wall, at least one of said walls comprising at least one locking element for at least one component, selected from between an upper pillow and a covering shell, arranged on a respective laminar portion.
- These aims are also achieved by a machine for sewing upper pillows on covering shells for mattresses, characterized in that it comprises a supporting structure for at least one coupling frame for upper pillows and covering shells for mattresses, which is associated with respective movement elements that are arranged on said structure, and a guiding track for at least one sewing head, said sewing head being translationally moveable along said track in a direction at right angles to the direction of motion of said frame on said structure, said frame having a substantially rectangular shape and comprising at least one laminar portion that is co-planar with a lower edge thereof, said frame comprising at least one locking element for upper pillows and covering shells for mattresses arranged on the at least one said laminar portion.
- The above mentioned aims are further achieved by means of a method of sewing upper pillows on covering shells for mattresses, which comprises:
-
- arranging a covering shell for mattresses on a coupling frame the dimensions and shape of which are complementary to those of said shell, said frame comprising at least one laminar portion that is co-planar with a lower edge thereof;
- juxtaposing, on said covering shell accommodated in said frame, a respective upper pillow;
- coupling, by means of at least one locking element of said frame, said upper pillow and the respective covering shell for mattresses on the at least one said laminar portion;
- aligning said frame, within which said shell and said upper pillow are mutually juxtaposed and accommodated, with a sewing head that surmounts said frame, for the coupling, by way of stitch lines, of said upper pillow and said covering shell.
- Further characteristics and advantages of the invention will become better apparent from the detailed description that follows of a preferred, but not exclusive, embodiment of the frame for sewing upper pillows on covering shells for mattresses, of the machine for sewing upper pillows on covering shells for mattresses, and of the method of sewing upper pillows on covering shells for mattresses, according to the invention, which are illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
FIG. 1 is a schematic perspective view of a frame for sewing upper pillows on covering shells for mattresses according to the invention, above which the respective shell and the respective pillow are shown exploded; -
FIG. 2 is a schematic perspective view of the frame inFIG. 1 accommodating the respective shell, surmounted by the respective pillow; -
FIG. 3 is a schematic perspective view of the frame inFIG. 1 accommodating the respective shell and the respective pillow; -
FIG. 4 is a schematic perspective view of the frame inFIG. 3 during the step of stitching the pillow to the shell; -
FIG. 5 is a schematic perspective view of the manufactured article constituted by the shell to which the respective pillow is coupled; -
FIG. 6 is an exploded perspective view of a mattress constituted by a central body comprised between two covering shells, in which the upper shell is coupled to the respective pillow; -
FIG. 7 is a schematic perspective view of a machine for sewing upper pillows on covering shells for mattresses according to the invention, in a first step of operation; -
FIG. 8 is a schematic perspective view of the machine inFIG. 7 in a second step of operation; -
FIG. 9 is a schematic perspective view of the machine inFIG. 7 in a third step of operation; -
FIG. 10 is a schematic perspective view of the machine inFIG. 7 in a fourth step of operation. - With reference to the figures, the
reference numeral 1 generally designates a frame for sewing upper pillows A on covering shells B for mattresses C, and thereference numeral 2 generally designates a machine for sewing upper pillows A on covering shells B for mattresses C. - The
frame 1 for sewing upper pillows A on covering shells B for mattresses C comprises fourperimeter walls 3. - Each one of the
walls 3 is perpendicular to the twocontiguous walls 3 and comprises at least onelaminar portion 4 that constitutes a resting surface: in practicesuch laminar portion 4 defines a sort of shelf that is co-planar with a lower edge of therespective wall 3. - It is further necessary to specify that at least one of the
walls 3 comprises at least onelocking element 5 for at least one component, selected from between an upper pillow A and a covering shell B, arranged resting on arespective laminar portion 4. - It should be noted that each
wall 3 can effectively comprise at least twobands wall 3 that they define. - According to a particular embodiment,
such bands angular bands 6 will define two mutually opposite corner edges of theframe 1 and theangular bands 7 will define the two remaining corner edges (which are also mutually opposite). According to the embodiment described in the accompanying figures, thebands 7 will be accommodated in respective axial cavities of thebands 6, being able to slide inside them. - The possibility is not ruled out that each
wall 3 can comprise at least two coaxial bars, one inside the other, which can slide telescopically in order to vary the overall length of thewall 3 that they constitute: such bands will preferably be associated with laminar elements that are adapted to delimit the surface of eachwall 3. - The at least one
laminar portion 4, which constitutes the resting surface for the shell B, can extend for the entire length of therespective wall 3. In such case thelaminar portions 4 will define a lower resting border that lies on the plane that contains the lower edge of thewalls 3. - It should further be noted that each
wall 3 will advantageously comprise at least onerespective locking element 5 of the at least one component arranged on arespective laminar portion 4. - More specifically each
locking element 5 is movable from a free configuration, in which one of its ends is spaced from arespective laminar portion 4, to a coupling configuration, in which the same end faces and is proximate to therespective laminar portion 4 in order to fasten the at least one component, selected from between an upper pillow A and a covering shell B, which is interposed between them. - It is evident that an effective positioning can be obtained by adopting
several locking elements 5 in eachwall 3, so as to ensure a good level of stability of the shell B and of the pillow A. - The
locking elements 5 can be elastically deformable contoured plates that are pivoted to thewall 3. - The possibility is not excluded of adopting, as
locking elements 5, actual clamps that are conveniently pivoted to thewall 3, sliders that can be locked in preset positions, or any other coupling means that make it possible to stably and detachably fix the shell B and the pillow A on theportion 4. - The possibility of varying the length of each
wall 3 of theframe 1 is advantageous in terms of the versatility that it assumes: in fact it can be used indifferently for locking shells B and pillows A that are intended for mattresses C for a single bed, for a twin bed, for a double bed and/or mattresses C with nonstandard measurements. - Note should also be taken of the characteristics of the
machine 2 for sewing upper pillows A on covering shells B for mattresses C; such machine comprises a supportingstructure 8, for thecoupling frame 1. - The supporting
structure 8 comprisesmovement elements 9 and 10: in particular these are toothed belts and/or chains that can be coupled to theframe 1 for its entrainment. - The entrainment of each
frame 1 will be carried out according to two different methods: a first method relates to the transfer of theframe 1 from the loading station (which is generally arranged on one side of the machine 2) to a sewing station (which can be arranged at the opposite end, formachines 2 with a simpler structure, or in a central portion of themachine 2, formachines 2 that are provided with two mutually opposite loading stations). - In the second method the movement imparted by the belts and/or by the chains and provided by a respective actuation motor will be controlled by the sewing operations.
- The possibility is not excluded of providing a
machine 2 that is provided with at least one loading station on multiple superimposed levels: at a lower level there is aframe 1, which is loaded with the shell B and the pillow A (which are superimposed and locked in place), and which will be transferred to the sewing station, while at an upper level there is aframe 1 that is empty (or which contains a shell B and a pillow A that are mutually interconnected with lines or sections of stitching) for the loading (or unloading) operations. - The
machine 1 further comprises a guidingtrack 11 for at least onesewing head 12; thesewing head 12 can perform a translational movement along therail 11 in a direction at right angles to the direction of motion of theframe 1 on thestructure 8. - It should conveniently be pointed out that the
structure 8 will comprise positively arecess 8 a at the sewing head 12:such recess 8 a must allow the needle of thesewing head 12 to move to a level lower than that of thestructure 8 itself (thus passing through the shell B and the pillow A that are placed on theframe 1 that is arranged on the structure 8) in order to complete each stitch via arespective abutment 13. - It should be noted that, similarly to what is described previously, the
frame 1 will preferably have a substantially rectangular shape and will comprise at least onelaminar portion 4 that is co-planar with a lower edge thereof; theframe 1 will further comprise at least onelocking element 5 for upper pillows A and covering shells B for mattresses C arranged on the at least onelaminar portion 4. - According to a particular embodiment of undoubted practical and applicative interest, the guiding
track 11 can be arranged substantially at the centerline of themachine 2, and in such case thestructure 8 will be constituted by a sliding surface of size adapted to the accommodation and movement of at least one frame 1:such movement elements - This construction choice is dictated by the necessity to precisely define the instantaneous position of the
frame 1 at every moment: the presence of teeth (toothed belts) or links (chains) enables a very precise movement of theframe 1 on thestructure 8. - The
movement elements sewing head 12 for the coordinated movement of thehead 12 along thetrack 11 and of theframe 1, through theelements structure 8. The coordinated movement makes it possible to provide lines and portions of stitching of any length, direction, and shape, optionally even with superimpositions thereof, which enable the creation di embroidery, patterns and the like. - The expediency of having two
separate movement elements frame 1 still (for the loading and unloading operations), while the other is facing toward thesewing head 12 and is moved by therespective element sewing head 12 on the respective rail 11: the coordination of the two motions described is driven by the control and management unit. - Finally, it should be noted that the
sewing head 12 is functionally associated with a respective abutment 13 (previously mentioned) that is controlled by it:such abutment 13 is adapted to the completion of the sewing operations (comprising thus the elements necessary for the formation of the single stitch, such as the crochet hook and the corresponding spool of thread). - With regard to the production of shells B coupled to respective upper pillows A with which to provide the upper covering of a mattress C, it is possible to adopt a sewing method that comprises a series of consecutive steps.
- Firstly it is necessary to arrange a covering shell B for mattresses C on a
coupling frame 1 of complementary size and shape to the size and shape of the shell B. Theframe 1 must necessarily comprise at least onelaminar portion 4 that is co-planar with a lower edge thereof. - Subsequently a respective upper pillow A will need to be juxtaposed on the covering shell B accommodated in the
frame 1. - Such juxtaposition will be facilitated by the presence of the
walls 3 of theframe 1 which will guide the insertion of the pillow A, imposing the correct centering thereof with respect to theframe 1. - It will then be necessary to couple, by means of the at least one
locking element 5 of theframe 1, the upper pillow A and the respective covering shell B for mattresses C on the at least onelaminar portion 4. - Then comes a step of alignment of the
frame 1, within which the shell B and the upper pillow A are mutually juxtaposed and accommodated, with asewing head 12 that surmounts the frame 1: thehead 12 will perform the coupling, by way of stitch lines, of the upper pillow A and the covering shell B. - It should be noted that, before the step of arranging the shell B and the pillow A within the
frame 1, there is a step of adjustment of the length of the walls of the frame 1: eachwall 3 is in fact constituted by at least two components (for example twobands 6 and 7) that can translationally move with respect to each other in order to determine a variation of the overall length of thewall 3 that they define. - It is further emphasized that, following the translational movement of the
frame 1, containing the shell B and the pillow A, and following the sliding of thesewing head 12 along arespective guiding track 11, the stitch lines can have any orientation, shape and/or pattern. - Advantageously, the present invention solves the above mentioned drawbacks by providing a
frame 1 for sewing upper pillows A on covering shells B for mattresses C which makes it possible to juxtapose the pillow top A and the respective covering shell B in a simplified manner, thus facilitating their subsequent coupling. - Conveniently, the
machine 2 for sewing upper pillows A on covering shells B for mattresses C is completely automated. - Positively such automation of the
machine 2 determines a high rate of productivity thereof. - Conveniently, the above mentioned automation of the
machine 2 makes it possible to obtain a constant qualitative standard of the semi-finished products that it produces. - Positively the method of sewing upper pillows A on covering shells B for mattresses C according to the invention is particularly simplified, requiring a minimal application of labor.
- The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
- In the embodiments illustrated, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other embodiments.
- In practice, the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
