Abstract

The present utility model pertains to the field of exercise apparatus, and relates to a novel configuration for a cable bar to be attached to a pulley of an item of equipment for the performance of muscle exercises which eliminates the limitation of movements during exercise.

Description

"CONFIGURATION APPLIED TO CABLE BAR FOR EXERCISE"

[01] The present utility model deals with a new barbell configuration for exercises, specifically a cable bar to be connected to a pulley, which is a type of physical conditioning machine, to perform muscular exercises.

[02] FUNDAMENTALS OF THE TECHNIQUE - There are many exercise bars that can be attached to the equipment, each one with its specific application. Such bars allow you to perform several variations of movements, although the capacity of these movements is limited.

[03] The exercise bar type equipment found on the market has a fixed pole, which does not rotate, preventing the user's wrist from moving properly, causing muscle trauma due to inadequate movement, since, when the wrist does not rotate naturally with the movement of the exercised, it creates tension compensation in the wrist itself in the hand and, as a reflex to compensation, in the elbow, shoulder and tension in other parts of the body.

[04] In the Patent Bank of the INPI, we find the Privilege of Invention PI0401560-6, which reveals a "MULTIFUNCTIONAL BAR WITH MOBILE HANDLE", to support weight washers, for weight training and muscle toning exercises, which has a differentiated configuration with mobile wrist that allows the movement and positioning of the wrist in the way that the user wants and/or is allowed to perform the exercise in the best possible performance and yield. The bar can be used in weight rooms, sports training centers and orthopedic rehabilitation and physiotherapy clinics.

[05] Additionally, we find US20190184225 in the international patent bank, which deals with an ergonomic structure for exercises with a detachable handle, applicable to accessory handles for machines and dumbbells. Said process reports one bar parallel to the other with a hand ring at both ends of the parallel bars.

[06] The international patent bank further discloses US 7862486, illustrating a bar with two annular configuration bearings mounted at opposite ends of the bar. The handles are located inside the housings. Two sets of bearings that are diametrically opposed to each other at the ends of each handle.

[07] Further, US4779867, illustrating an elastic band attached to a cable with stirrups attached at each end and an elongated bar having ends that receive a central portion of the cable and keep the stirrups separate from one another during use. Each end of the bar has a U-shaped fork that guides the bar handle. [08] These models presented have some disadvantages since the ring or fork, in orders that have a handle support for the fitting of the hands, allow the wrist to be moved, however, there is no possibility that the user can move the position of the hands of the ring/fork during the exercise, since the support is fixed and, in order to change the position of the hands, it is necessary to remove them and put them back in a new position.

[09] Another disadvantage that can be mentioned, and is present in PI 0401560-6, specifically, is that each user having a different size will lose time to perform the exercise since he will have to adjust the bar every use .

[010] UTILITY MODEL PROPOSAL - The utility model described aims to provide a device designed to carry out the exercise in a practical and efficient way, as the applicant adds two rotating poles to the cable bar in which it is possible to hold and move the wrists in the opposite way during the exercise. Therefore, while one wrist is in flexion, the opposite wrist is in extension, allowing the user to connect the arms to the movements described in the natural human gait cycle.

[011] Said opposite movement during the exercise reaches the natural human gait cycle, since there is a phase of support and another for oscillation. This is the natural and healthy movement, with the help of the necessary wrist turn.

[012] Normally, with what is available on the market, when the user holds the cable bar, it remains fixed with a single pole and does not allow oppositional movement of the wrists during use. required lever.

[013] With that in mind, the applicant divided the bar into two poles, adding rotational components to the cable bar, specifically two rotating poles in a single bar, which allow for a greater variety of exercise and muscle activity when in use. It also allows the user to make movements with the wrist, elbow, shoulder, rib cage and body, moving them in the correct cycle, which would not be possible with a traditional cable bar.

[014] When the user exercises with the current cable bars, once they grip it, the handles remain fixed in that position as the existing bars are held in a solid piece, with a single pole.

[015] The addition of rotational components to the cable bar allows for a greater variety of exercises and muscle activity when using it.

[016] The cable bar has two rotating tubes that are attached to the axis of the bar (main steel central piece), with bearings that are between the tubes and the bar . This formatting allows smooth rotation of the tubes, which rotate in both directions, freely, without resistance or limitations.

[017] The eye bolt is fixed to the shaft at one end of the bar through the use of housing, and a suitable glue can be used that makes convenient contact of the thread on the eye bolt and in the housing, allowing ensure that the cable bar is securely attached to a pulley, ensuring that it does not unscrew during use.

[018] In addition, there are bearings positioned between each tube to separate them and at both ends of the cable bar, between the tube ends and the eyebolt housing. This prevents friction and facilitates smooth rotation of the rotating tube.

[019] The new cable bar model with rotating tubes allows creating an opposite movement with both wrists at the same time. This allows the user to flex one wrist while extending the other, connecting the forearms to the rest of the body. This would not be possible with existing bars as the wrists and hands are forced to remain fixed to the handle bar, inhibiting its ability to create swinging motions with the wrists in analogous or opposite directions.

[020] DESCRIPTION OF FIGURES For a better and adequate understanding of the model, it is now described with the help of the attached figures, where:

Figure 1 shows the cable bar with the structure assembled; Figure 2 shows a cross-section A showing details of the cable bar, such as: A bearing cup (m) , an alien bolt (p) , a bearing lock washer (L), two deep protective grooves (1) ), a swivel bearing housing (h), four thrust bearings (e), a loop tube (f), two shims (g);

[021] DETAILED DESCRIPTION - According to the figures, it was possible to contemplate a bar (1) with the following components: two tubes (d, f); an inner central tube, here identified as the cable bar axis (a); four pulse bearings (e) being fitted to each end of the tubes (d, f); a shaft end (c) that couples to an eye bolt (n); three shims (g) located on one side of each end of the tubes (d, f) and one in the juxtaposition of the two tubes; a swivel bearing housing (h) located close to the bearing cup (m); a bearing lock washer (L); and two deep protective grooves (I) next to the bearing housing (h) .

[022] The cable bar (1) has two rotating tubes or outer sleeves (f, d) that are attached to the axis or central tube (a) of the bar (1). The main, central piece (a) has a cylinder below the tube, allowing them to rotate smoothly.

[023] The tubes (f, d) rotate in both directions, freely, without resistance or limitations.

[024] The eye bolt (n) is fixed to the housing

(h) from the axis of the bar (a) that penetrates the screw thread eyelet (n) , ensuring that it does not unscrew during use.

[025] The eye bolt (n) also rotates freely in both directions, which ensures that it does not suffer any mechanical stress, to prevent accidents.

[026] Housing (h) keeps all components in place and facilitates fixing the eye bolt (n) to the shaft.

[027] This rotating movement was not possible with traditional cable bars, because the wrists and hands are forced to remain fixed to the bar, inhibiting the user's ability to create opposing movements, and without this function, it was impossible to connect the forearms. to the rest of the body, respecting the cycle of human gait.
