CONFIGURATION APPLIED TO A CABLE BAR FOR EXERCISE

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

This utility model deals with a new exercise bar configuration, specifically a cable bar to be connected to a pulley, which is a type of fitness machine, for performing muscular exercises.

TECHNICAL BASES

There are many exercise bars that can be attached to the equipment, each with its own specific application. Such bars allow you to perform several variations of movements, although the capacity of these movements is limited.

The equipments like exercise bar found in 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, as when the wrist does not rotate naturally with the exercise movement, it creates a tension compensation in the wrist itself in the hand and, as a reflex for compensation, in the elbow, shoulder, and tension in other parts of the body.

At INPI's patent database, we found the Invention Privilege PI0401560-6, which discloses a “MULTIFUNCTIONAL BAR WITH MOBILE WRIST”, to support weight rings, for bodybuilding exercises and muscle toning, which displays a differentiated configuration with a movable wrist that allows the movement and positioning of the wrist in the way the user wants and/or is allowed for the execution of the exercise in the best possible performance and output. The bar can be used in weight training rooms, sports training centers, and orthopedic rehabilitation and physical therapy clinics.

Additionally we found in the international patent database US20190184225, which deals with an ergonomic exercise frame with detachable handle, applicable to cable attachments for machines and dumbbells. This process describes one bar parallel to the other with a hand ring at both ends of the parallel bars.

The international patent database further reveals U.S. Pat. No. 7,862,486, 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.

In addition, U.S. Pat. No. 4,779,867, which illustrates an elastic band fixed to 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 each other during use. Each end of the bar has a U-shaped fork that guides the bar cable.

These models have some disadvantages since the ring or fork, in the application that have a handle support to fit the hands, allow the user to move the handle, but there is no possibility that the user can move the position of the hands of the ring/fork during the exercise as 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.

Another disadvantage that can be mentioned is present in PI0401560-6, specifically, is that each user having a different size will lose time for the execution of the exercise since they will have to adjust the bar each time, they use it.

UTILITY MODEL APPLICATION

The described utility model is intended to provide a device designed to perform the exercise in a practical and efficient manner, because the applicant adds to the cable bar two rotating poles on which it is possible to hold and move the handles in an opposing manner 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.

This opposite movement during exercise catches up with the natural human gait cycle since there is a support phase and an oscillation phase. This is a natural and healthy movement, with the help of the necessary twist of the wrist.

Normally, with what is on the market, when the user holds the handlebar, it remains fixed with a single pole and does not allow for opposition movement of the wrists during use, and the necessary leverage is not possible.

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

When the user exercises with the current cable bars, once he grips it, the handles remain fixed in that position because the existing bars are made in one solid, single-pole piece.

The addition of rotational components to the handlebar allows a greater variety of exercises and muscle activity when using it.

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

The eyebolt is attached to the shaft at one end of the bar using a housing, and a suitable adhesive can be used that makes convenient contact of the thread on the eyebolt and the housing, allowing the cable bar to be securely fastened to a pulley, ensuring that it does not unscrew during use.

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.

The design of the new cable bar with rotating tubes allows you to create 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 the existing bars because the wrists and hands are forced to remain fixed to the cable bar, inhibiting their ability to create oscillation movements with the wrists in analogous or opposite directions.

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, herein identified as the cable bar shaft (a); four wrist bearings (e) being fitted to each end of the tubes (d, f); a shaft end (c) which connects to an eyebolt (n); three shims (g) situated on one side of each end of the tubes (d, f) and one at the juxtaposition of the two tubes; a slewing bearing housing (h) situated near the bearing cap (m); a bearing lockwasher (L); and two deep protective grooves (I) adjacent to the bearing housing (h).

The cable bar (1) has two rotating tubes or outer sleeves (f, d) that are attached to the shaft or center tube (a) of the bar (1). The main, central part (a) has a cylinder below the tube, allowing it to rotate smoothly.

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

The eyebolt (n) is attached to the housing (h) of the bar shaft (a) that penetrates the thread of the eyebolt (n), ensuring that it does not unscrew during use.

The eyebolt (n) also rotates freely in both directions, and this ensures that it does not suffer any mechanical stress, to prevent accidents from occurring.

The housing (h) holds all the components in place and makes it easier to attach the eyebolt (n) to the shaft.

This rotational 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 human gait cycle.
