Abstract

The system comprises a weight (1) which is gradually displaceable along a rocking guide (10) which oscillates when the user performs an exercise by pulling the same weight (1) during the exercise for each determined position of the weight (1) along the rocking guide (10). The displacement of the weight (1) along the rocking guide (10) increases or reduces gradually the weight for the exercise of the user, through a combination of a resistance arm consisting of the weight (1) displaceable along the rocking guide (10) and of two power (4) and resistance (5) wheels associated to each other through a transmission means (7), the power wheel (4) being connected to the user-actuated means (13, 14) and the resistance wheel (5) being connected to the shaft (3) of the rocking guide (10).

Description

Automatic weight regulation system in gym equipment.

The present invention relates to an automatic system of weight regulation in gymnastic apparatus.

Currently, in the maguinas of bodybuilding, gymnastics, etc., there are on the market electronic systems by compressed air through ci. Lindros and iron plates that make up a block - formed by 5 or 10 kg plates. and with a weight per block ranging between 25 and 200 kg. according to the machine and the exercise it performs.

Both electronic and air, have the disadvantage of making an effort - - irregular, presenting difficulties when performing - - exercises especially in professionals and physical trainers. At present, in gyms and professional centers, machines are generally used - with iron plates forming a block, this system being the most used because the effort made is the most real and compensated, although it presents a important problem as soon as you want to increase or decrease weight, since at this time you have to interrupt the exercises and place the weight selector at a point in the block that you want and resume the exercises with more or more Weigh, which greatly impairs training, both by the stop and the sudden change in weight.

The system of the present invention eliminates said problems, since the weight enters progressively and automatically without the need to paralyze the exercises. With the system of the invention, the pre

"~ ¡£ r - ε» •>-Je; ~ -% ¿_t; The parador or the person in charge of the physical preparation can program the weight and repetitions in advance that he deems most convenient for the person who is going to perform the exercises, getting a perfect workout.

Among the advantages presented by the system of the present invention can be mentioned: a) Automatic entry and exit of weight, without the need to interrupt the exercises; b) The weight can be programmed, as well as the number of repetitions; c) Balanced effort from beginning to end of the exercise; d) Entry and exit of the machine with - - set to 0 kg., which greatly facilitates the position and starting of the exerciser; e) The machine has some programs - standard or standardized, being able to be selected according to professional criteria or medical recommendations; f) A control of the training system of the improvements made physically, from a date previously registered through a computer system; and g) Weight regulation in fractions of - grams.

In accordance with the foregoing, the weight control system in gymnastic apparatus object of the present invention is essentially characterized in that it consists of a gradually collapsible weight along a swinging guide which is oscillating by the action of the user during the exercise, which consists in oscillating the tilting guide with the weight in

HO ^ REPLACED a certain position along the swing guide by dragging the user the same weight during the exercise for each determined position of the weight along the swing guide, in which the weight travel along the guide The weight gradually increases or decreases the weight for the user's exercise, which is done by a combination of a resistance arm - constituted by the weight that can be moved by the guide and the power wheels and resistance - related to each other by means of transmission, when the power wheel is connected to the means operated by the user and the resistance wheel - to the axis of the tilting guide.

According to the invention, the user makes the gradual displacement of the weight by the tilting guide by increasing or decreasing said weight, during the performance of the exercise without stopping said exercise, or it can be programmed, and possibly repetitively.

Said weight is moved along the tilting guide by motor means driven by the user, and possibly on a scheduled basis.

Preferably, said weight is displaced by a spindle driven by a motor guided in - - longitudinal bars.

For its part, the power wheel is eccentric in terms of the axis of rotation, and eventually in terms of the contour where the transmission is wound with respect to the resistance wheel during the oscillation of the tilting guide, so that when doing the exercise the user for each position of the weight in the tilting guide performs the same - - drag of weight.

SUBSTITUTED SHEET According to the invention, the entire assembly of the tilting guide with the weight movable along the same by motor means and the corresponding guides is mounted on a frame, and the power and resistance wheels with the Rack are mounted on a bench resting on the ground.

It should be noted that the displacement of the peso and the increase or decrease of the same for the - - exercise of the user are gradual in infinite or tesimal order.

To facilitate a more detailed explanation and understanding, two sheets of drawings are attached in which a practical case of realization of the automatic weight regulation system in gymnastics equipment of the facets is shown. indicated, shown only for illustrative purposes and not limiting the scope of the present invention.

In these drawings:

Figure 1 is a side elevation view schematically illustrating the system of the present invention.

Figure 2 is a perspective view - schematically illustrating an example of application of the system of the invention to one of the weight training apparatus.

In accordance with the drawings, the automatic weight regulation system in gymnastic apparatus object of the present invention consists of a weight -1- in the form of a block comprising several -1-attached weights, the weight of which - 1- it can be moved gradually, along the arrow -F1- along - a guide -2- tilting on an axis -3-, whose - guide -2- is oscillating by the action of the user du- During the exercise in the corresponding apparatus, whose guide -2- swingarm consists of two parallel bars upper -2a- and lower -2b-, and said exercise consisting in swinging the swinging guide -2- with the weight -1 - located in a certain position along the swing guide - according to the arrow -F2- (see figure 1), with which - - which the user drags the same weight during the - exercise - for each position of the weight in the guide - bascul ante-.

In said displacement -F1-, towards one or the other end of the tilting guide -2- of the weight -1- along said tilting guide, the weight to - do the exercise by the user increases or decreases gradually, which is done by a combination of a resistance arm - -BR- consisting of the weight -1- that can be moved by the tilting guide -2-, and a power wheel -4- connected to the means operated by the user and a resistance wheel -5- arranged on the axis -6- of the rocker guide -2-, whose power wheels -4- and resistance wheels -5- are interrelated - by transmission means consisting of a ca_ dena -7-.

It should be noted that the power wheel -4- is eccentric in terms of the axis of rotation, and in its case, and according to the path - greater or lesser length - that the weight must move, can be eccentric in - as to the contour (eccentric, oval and mixed contour), on whose contour the transmission (chain -7-) is coiled with respect to the resistance wheel -5- during the oscillation of the tilting guide -2-, so that when the user does the - - corresponding exercise for each position of the pe

SHEET SUST2TUΪDA so -1- in the rocker guide -2 - _ performs the same weight drag.

According to the system of the present invention, the user can make said gradual shifting of the weight -1- along the tilting guide -2- increasing or decreasing said weight, during the exercise without the need for Stop the exercise. According to the invention, said gradual displacement of the weight may be programmed and, where appropriate, repetitively in accordance with the characteristics of the user.

According to the invention, the weight -1- is moved along the guide -2- by means of a motor -8- operated by the user with a button or in programmed mode, as indicated in the previous paragraph - . As illustrated in the figures, this weight is displaced by the motor -8- by - a spindle -9-.

The rocker guide assembly -2- consisting of the bars -2a-, -2b- with the weight -1- can be moved along them by means of the spindle -9- driven by the motor -8- is mounted on a frame -10-, which with the power wheel -4- and the resistance wheel -5- are - mounted on a bench -11- resting on the ground.

According to the system of the present invention, the displacement of the weight -1- and the increase or decrease thereof for the exercise of the user, are graduates of infinitesimal order, although in practice the increase or decrease is by gra or kilograms

In the example application, illustrated - in Figure 2, the automatic system of weight adjustment to a gymnastic apparatus with

creto, although it is applicable to any type of gym equipment. In said example, the user sits in an armchair -12- (illustrated in dashed line in said figure 2) and arranges the feet below - under a thrust support -13- (illustrated in 1 ^ line of strokes) in combination with a counterweight -14- so that the thrust support -13- can return to the initial position, all in accordance with the conventional arrangement of these devices.

In unification, the user with a button -not illustrated- has the weight -1- in a specific position along the tilting guide - -2-, sitting in the chair -12- and - - - with the two feet located under the pusher support -13- raise the tilting guide -2- with the weight - -1- upwards by turning the power wheel -4- according to the arrow -F3-, which by means of the chain - 7 - rotates the resistance wheel -5- according to the arrow -F4- and through the axis -6- the frame is raised -10- (with weight -1- and the tilting guide -2-) upwards according to arrow -F2-. When the frame reaches the high point - whose ascension is illustrated in dashed lines - in correspondence with the high point of the support and bidder -13- the reverse path is made and then restarted. ^'

Of course, the displacement -F1- of the weight -1- along the tilting guide -2-, according to the invention can be carried out by means of the motor -8- and the spindle -9-, or by any other pneumatic, hydraulic, etc. Likewise, the transmission -7- between the power wheel -4- and the resistance wheel -5-, can be any convenient, either by means of the

SUBSTITUTED SHEET dena illustrated and described, or by a strap of any convenient section, or by any other means.

Likewise, and as indicated and - in correspondence with the rotation that the frame has to make -10-, the power wheel -4- can be eccentric with respect to its axis -4a-, or eccentric with respect to to the contour where the transmission is rolled -7-, whose contour can - present any eccentric, oval, mixed, complex convenient configuration, so that for each position of weight -1- in the tilting guide -2-, the weight that the user carries during the exercise is always the same.

Similarly, the constitution of the bastj_ dor -10- and the bench -11- may be the one illustrated or any more convenient.

It should be understood that in the realization - practice of the automatic weight regulation system in gymnastic apparatus object of the present invention, as many detail variations as may be deemed appropriate may be made provided that the essential characteristics thereof are not altered. They are summarized in the following claims.
