Abstract

The invention relates to a lever expander with a support, which comprises a wound torsion spring and each working arm of which is or comprises a lever, at the end of which is a support for the forearm, a handle being provided between the spring and the support and being perpendicular or parallel to the spring axis, wherein the center of each support is located in the middle plane of the spring and each handle, irrespective of the position thereof, is located above that plane. The expander has an angled lever for the chest muscles with the supports on the inner side of the forearms, and has crossed levers for the shoulder and back muscles with the supports on the outer side of the forearms. The expander can also include two springs arranged on opposite sides of a crossbar and having parallel axes. The handles and the abutments are formed by bends in the levers, and the levers are coated with a rubber or polymer material.

Description

The lever expander with emphasis Technical field of the Invention The invention relates to portable sports devices, specifically to expanders using a twisted torsion spring as an elastic resistance for developing the muscles of the arms and shoulder girdle, and for home use. Prior art

Currently, many portable sports simulators are being proposed for developing the muscles of the arms and shoulder girdle, which use elastic elements to create a resistance load. Some of them are designed for a specific muscle group, such as a chest or shoulders, by creating an imitation of movements performed by exercising on special exercise machines that isolate a specific muscle group during exercise. When creating portable simulators, specifically for the muscles of the chest of the shoulders, technical difficulties arise to create the same trajectory of arm movement and efficiency as on special simulators, which is expressed either in an uncomfortable position of the hands during training or in a complex constructive implementation of portable simulators.

The closest is a simulator, patent JP 2005152077 (A), consisting of a twisted torsion spring with two working shoulders, whose ends are perpendicular to the working shoulders and parallel to the axis of the spring, and the ends themselves are stops for the forearms. Exercising holds with both hands on the spring and forearms hands rests on the stops. The torsion spring has a good resistance load, but the lack of handles and the uncomfortable position of the hands reduces the effectiveness of the workout. DISCLOSURE OF INVENTION

The objective of the invention is to create a portable sports expander, simple in design, with maximum efficiency, well isolating trained muscle groups, and having a comfortable arm position during exercise

The problem is solved by using as the elastic resistance of a twisted torsion spring, in which each working arm is either a lever, or the arm has a lever, at the end, which is an emphasis for the forearm, located parallel to the axis of the spring, and symmetrically the emphasis on another lever, and between the spring and the emphasis, on the lever is a handle located either perpendicularly or parallel to the axis of the spring, and symmetrically to the handle on the other lever, and to eliminate the moment of force that expands the expander around the middle of the spring axis, in the direction perpendicular to the spring axis, during the compression of the levers with the forearms, the middle of each stop is on the middle plane of the spring, and each handle a, or its middle, at any of its location is above this plane, due to which the hand is always located at an angle to the forearm, which eliminates the tension in the wrist area, while the middle of the spring axis and the middle of each abutment form the vertices of the triangle, and each spring lever has an angle, which is either at the location of the handle, either before or after it.

In the case of shoulders and back, the levers intersect each other, and each lever has two, successively located, opposite corners, symmetrically to the corners on the other lever, one of which is located between the spring and the crossing, and the other after the crossing. either at the location of the handle, or before it, with the middle of the spring axis and the middle of each abutment forming between the vertices of the triangle. The expander can be made with two springs, which have parallel axes and are on opposite sides of the crossbar, which is either a connection between the springs, or connects the shoulders of the springs to each other, while both springs have a common middle plane, on which is the middle of each stop, and the middle of the axes of the springs and the middle of the stops form between them the vertices of the quadrilateral, and the levers can be located either between the springs or on the outer sides of the springs.

In all variants, knobs and stops, on each lever, can be formed using bends that are symmetrical to bends on the other lever, and at the same time symmetric bends are located only on one side of the spring's central plane, or the common median plane of the springs, and in the version with crossed arms , the bends that form the angles on the levers, between the spring and the point of intersection of the levers, are located on different sides of the mid-plane of the spring. The levers, and the crossbar between the springs, may have additional bends, for example, on the stops, like contours for the forearm. The stops on the levers may have additional overhead stops, which are fixed on the lever and the main stop, or the lever may have a rigidly fixed stop, with a cutout for the fingers, which forms an additional handle. The expander, which has levers on the spring arms and an expander with a crossbar that connects the spring arms, bends either on the arms, or on the arms, or on the crossbar, or on the arms, and on the arms, or on the crossbar, and the lever or crossbar can be a tube . The expander may have a stopper covering each shoulder of its spring.

Levers, and crossbar, expander can be fully or partially covered, for example, only places for pens and stops, rubber or polymeric material, while the pens or stops can have a circular or oval cross section, and the stops can be used as handles, and additional overhead , or rigidly fixed stops, have contours for the forearms of the hands, and are made of polymers or wood, and covered with neoprene or fabric.

Industrial Applicability

The expander is simple in design, which allows its use without prior preparation. A lever expander with an emphasis, having a twisted torsion spring, to create resistance, while compressing or unclenching the forearms of the arms of the stops on the expander, creates a load on a specific muscle group, depending on the construction of the expander, for example, with crossed shoulders for the shoulder or back muscles, when the stops are on the outer side of the forearm, it is necessary to attract the expander to the body of the trainee. At the expander with the corners on the levers, which are designed for the chest muscles, just holding the handles and resting the forearms of the arms on the stops that are on the inside of the forearm, you need to remove the expander from the body of the exerciser, due to which the forearms of the arms begin to approach and compress the spring through the stops on the levers. The handles and the stops on the expander can be formed on the levers using bends that allow you to create various designs.

The use of lugs, for forearm arms, allows you to isolate a certain group of muscles, and create the same load on them as on special training machines, and the expander allows you to work out the muscles on several levels, for example, the expander for the chest muscles can be moved down or up.
