Abstract

The present invention refers to a framework for gym machines that houses and supports a central stack of vertically sliding main weights, as well as a lateral pair of auxiliary weights that can be joined to the central stack by means of a selector mechanism formed of an opposite pair of bolts that can be simultaneously actuated by the same lever.

Description

Description
Framework for gym machines able to house and support a selectable series of vertically sliding weights.
The present patent application refers to a framework for gym machines able to house and support a selectable series of vertically sliding weights. The purpose of the present invention is to widen the training capabilities offered by gym machines that use a stack of vertically sliding weights as resisting strength to oppose the athlete's muscular strength, which is lifted by means of a rope tensioned with mechanisms or levers actuated by the athlete. The overlapping series of weights is located inside a framework, usually composed of a rectangular high narrow metal frame that projects from a base and is provided with a parallel pair of identical circular bars that extend vertically between the upper and lower cross-piece of the framework.
The pair of uprights acts as supporting and sliding guides for the overlapping series of weights, with each weight consisting in a metal brick, shaped as a parallelepiped and having a series of three aligned holes with vertical axis, with one central hole and two lateral holes, in symmetric opposite position. The pair of vertical bars is inserted into the two lateral holes, so that the entire stack of weights can slide repeatedly in vertical direction along the bars without losing the perfect overlapping of all metal bricks in the stack. These machines are also provided with a device used by the athlete to select the number of weights in the stack to be lifted during the exercise, so that each user can adjust the physical effort to his/her own skills or training level. The selector device comprises a vertical rod hung to the lifting rope and provided with a series of regularly spaced through holes where the athlete can insert a suitable pin. Each weight is provided with a central through hole with horizontal axis that receives the pin used to couple a brick from the stack to the perforated rod inserted into the stack.
By tensioning the lifting rope, the stack of weights formed by the brick hooked to the perforated rod and all the bricks above it is lifted. For expert scrupulous body-builders, the possibility to select one or more bricks has not proved fully satisfactory, since the physical effort required for each exercise can be adjusted only by integer multiples of the weight of each brick, since all bricks of the stack have the same dimensions and are made of the same material. The purpose of the invention is to widen the adjustment range of this type of gym machines with reference to the athlete's physical effort, by means of an auxiliary resistance mass, which can be selected by the user and has a lower weight - preferably one half - than the weight of each brick stacked into the framework. Another purpose of the invention is to house the auxiliary weight in a framework with traditional configuration, with the main purpose of reducing overall volumes and minimise structural modifications and adjustment costs. Another purpose of the invention is to design a selector mechanism of the auxiliary weight characterised by simple construction, easy use and operating safety and reliability.
All of the above purposes have been achieved by the invention, according to which the auxiliary resistance mass has been divided into two identical semi- masses, having the shape of two long narrow bars that are housed, protected and guided in a suitable vertical track applied to the internal lateral wall of the two uprights of the framework that supports the stack of selectable weights.
The selector mechanism of the two auxiliary semi-weights comprises an opposite pair of bolts applied above the highest brick of the stack and simultaneously actuated by the same manoeuvring lever that brings the two bolts closer or farther according to the rotation direction of the lever. The two bars are provided with a niche where the point of the bolts can be inserted, in order to join the highest brick of the stack to the two auxiliary masses.
For major clarity the description of the invention continues with reference to the enclosed drawings, which are intended for purposes of illustration only and not in a limiting sense, whereby:
- Figs. 1 and 2 shows a generic gym machine provided with the framework of the invention;
- Fig. 3 is an enlarged view of a detail of Fig. 2; - Fig. 4 is a top view of the framework of the invention without the upper cross- piece to show the selector mechanism of auxiliary weights that are not joined to the stack of main weights;
- Fig. 5 is the same as Fig. 4, with the only difference that the auxiliary weights are joined to the stack of main weights. With reference to the aforementioned figures, the framework (1) of the invention comprises a rectangular high narrow metal frame, formed of an upper cross- piece (2a), a lower cross-piece (2b) and a pair of lateral uprights (3), provided with a base (3a). A parallel pair of identical circular bars (4) extends vertically between the two cross-pieces (2a and 2b), which act as support and sliding guides for a stack of weights (5), with each weight consisting in a metal brick, shaped as a parallelepiped, and having a series of three aligned holes with vertical axis, with one central hole and two lateral holes, in symmetric opposite position. The bars (4) are inserted through the lateral holes, and the central hole of each weight (5) is used to insert a vertical rod (6) hung to a lifting rope (7) and provided with a series of regularly spaced through holes (6a).
Each weight (5) is provided with a through central hole (5a) with horizontal axis that receives a pin (8), whose dimensions allow to insert it also into one of the - A -
holes (6a) of the rod (6), so that the pin (8) can be used to hook any brick from the stack to the perforated rod inserted into the stack.
The framework (1) of the invention is characterised in that, apart from the stack of main weights (5), it also supports and guides two auxiliary weights (9), having the shape of two long narrow bars that are housed, protected and guided in a suitable vertical track (10) applied to the internal lateral wall of the two uprights
(3) of the framework (1 ).
The two auxiliary weights (9) can be joined to the first stack (5b) - that is to say the highest weight of the stack of main weights (5) - by means of a selector mechanism that comprises an opposite pair of bolts (11 and 12) applied above the brick (5b) and simultaneously actuated by the same lever (13) that turns around a pivoting pin (14) applied above the brick (5b).
As shown in Figs. 4 and 5, the lever (13) is hinged to both bolts (11 and 12) in two points (P1 and P2) in diametrically opposed position with respect to the pivoting pin (14).
The bolts (11 and 12) are formed of two metal rods that slide freely above the brick (5b), guided by fixed pins (11a and 12a) inserted into corresponding slots
(11 b and 12b), so that the actuation of the lever (13) can bring the two bolts (11 and 12) closer or farther according to the rotation direction of the lever. The two auxiliary weights (9) are provided with a niche (9a) used to insert the point of the bolts (11 and 12) when the same are pushed outwards and against the tracks (10) by means of the lever (13).
The tracks (10) also house a support plate for the auxiliary weights (9), which acts as stop for their downward travel. In the enclosed figures (15) identifies a screw used by change the stop position of the plate inside the tracks (10); this adjustment is mostly needed to align and perfectly centre the niches (9a) of the weights with respect to the point of the bolts (11 and 12).
