Description

The invention relates to the field of sports equipment and is intended for installation in a sports simulator for the implementation of load switching during training, aimed at the harmonious development of the main muscle groups of a person.

The load system of a sports simulator is one of the most important parameters when choosing a simulator.

The principle of operation of all known power simulators is the effect of weight on muscle groups during exercises (own or additional, which the apparatus itself gives). In load-block simulators (source: https://vash.market/sport-i-otdyh/trenazhery-i-fitnes/silovye-trenazhery.html), the latch holds the latch in the stack package. During the exercise, they move up and down the rod or guide cables, while maintaining a constant load on the muscles. In load-block simulators, the load is carried out due to the smooth movement of the latch in the cargo blocks. Weight change: Moving a latch that grips fewer flat weights. Mounting on extra weight - with holes and pin.

The disadvantages of the analogues are the following:

- the latch or plug-in pin is easily lost, and when using the cable for the convenience of the user, the cable is sometimes cut off;

- the need for the user to approach the weights when the user changes his training load. If another person, for whatever reason, is working with the simulator at the same time, there is a possibility that the user will be injured or crushed by a dropped load.

A well-known sports simulator (RU 2494783 C1, published 10.10.2013), containing two vertical supports mounted on the base, a platform mounted on supports with the ability to move along the supports, and loaders, further comprises two support arrows with a varying angle to the horizontal plane, fixed with the ability to move and fix around and along the central axis of the supports, and the loaders are made in the form of cable-block mechanisms consisting of blocks mounted on the platform and support arrows, and two cables, ha one end of each cable is attached to the platform through a mechanism allowing to change their length, and at the other ends of cables has a handle connected by a removable neck. In a well-known analogue, the load switching device is made in the form of cable-block mechanisms, consisting of blocks mounted on the platform and support arrows, and two cables. Each cable is attached at one end to the platform through a mechanism that allows you to change their length, and at the other ends of the cables are handles connected to each other by a removable bar.

A disadvantage of the known analogue is the lack of reliability and complexity of load regulation due to the presence of a cable-block system.

A well-known sports simulator (RU 2515434 C1, published: 05/10/2014, bull. No. 13), including a support frame with struts and an axis, a load guide and a lever with a handle pivotally mounted on the axis, a limiter for the lower position of the load guide, a limiter for moving the load and the load, the device is additionally equipped with a lever with a handle, and the load guide is rigidly installed between the load limiters in the vertical plane and is made in the form of a curved rod with two straight sections with an inflection, while straight sections are made at an angle not less than 2–3 degrees higher than the level of the horizon line at any position of the levers with handles, the load is made in the form of a set of separate loads and is located on the rail in the required percentage on both sides of the axis of the support frame, and the levers with the handles are pivotally mounted on the racks of the support frame symmetrically to the guide, and the limiter of the upper and lower positions of the levers is made in the form of a U-shaped frame fixed to them, and the axis of the support frame is made in the form of two coaxial half shafts rigidly mounted on the outer surfaces of the levers with handles, and pivotally - on the racks of the support frame.

A disadvantage of the known analogue is its low reliability. The analogue is intended for use on street venues, and the absence of a casing covering the loads and the system on which they are installed can lead to injury to the user, to rust from rains, and insecurity from vandalism. The inconvenience when choosing a load due to the fact that the user manually moves the loads along the guide. Performing exercises while lying on a bench, the user involuntarily sees loads hanging over him, which confuses him and worries that the loads may fall on his face or body.

Known simulator and load selection system (RU 2526776 C2, published: 08.27.2014, bull. No. 24) adopted for the prototype, containing a cargo foot to counter a specific training movement through a cable and pulley system, in which the cargo foot contains a set of goods, vertically stacked on top of each other and containing central holes made therein, through which the lifting rod is inserted from top to bottom, each load containing means for selecting cargo that are made with the possibility of articulated interactions action with a lifting rod with the provision of accession and a selected amount of cargo to the central lifting rod and fixing their relative.

The disadvantage of the prototype is its low reliability, due to the fact that each load has a load selection means, each of which pivotally interacts with a lifting rod inserted through the Central holes of the stacked loads, and the lifting rod is attached to the cable with pulleys, while the cable can to break off; if the cable breaks, a user pulling the handle through the cable and the pulley system using a cargo foot to counteract a specific training movement may be injured. It is also difficult for the user to select the load by hitting the hook-like means of selecting the load in the hole on the load. And the load selection means made in the form of a hook-shaped flat plate is easily deformed. In the prototype, only the cargo stack is protected by a casing preventing the user from drawing closer to the cargo stack, and the means for selecting goods outside the casing are controlled by a drive rod.

The technical result of the proposed invention is to increase the reliability of the device and ease of switching the load by the user.

The technical result is achieved by the fact that in the load switching device for a sports simulator, comprising a cargo foot with a means for selecting goods, a housing is introduced pivotally mounted on the frame of the sports simulator and rigidly connected to the load lever; a cargo stop with a means of selecting goods is placed in the housing, while the cargo stop is made in the form of a fan formed by a set of metal plates stacked on top of one another, pivotally mounted to the body and to the simulator frame from one end through holes in the metal plates, and from the other at the end, each metal plate of the cargo stack comprises projections for engagement, a load and a shock absorber; the cargo selection means comprises a guide link, a slider with a finger and a load switching handle, fixing elements in the form of combs rigidly fixed to the inside of the housing, the locking elements being installed so that their grooves are facing the finger; the slider is made with the ability to freely move along the guide link, which is pivotally attached to the wall of the housing from one end, and springy through the rod by an elastic element located under the housing cover; the load switching handle rigidly fixed on the slider is located in the longitudinal groove of the body, along the edge of which are marked the scale of the load size control, and the finger is designed to engage the loads on the protrusions of the metal plates of the cargo plate and fix them in the grooves of the combs is rigidly fixed on the opposite side of the slide with shift handle Each metal plate of the cargo foot is made up of two bent U-shaped plates connected by fastening elements, and the bent walls of one of the components of each metal plate are made narrower in the direction of connection with the other component of the metal plate. Holes for hinging to the body and to the simulator frame on each metal plate of the cargo foot are made on their bent walls. The loads are made in the form of flat plates fixed at the ends of the second part of the metal plates of the cargo foot. Shock absorbers are fixed under the metal plates of the cargo foot at the places of cargo securing. The loads are made with recesses intended for the reciprocal shock absorber of the upper metal plate of the cargo foot. The number of grooves of the fixing elements in the form of combs is one more relative to the number of metal plates in the cargo stop. The grooves of the fixation elements in the form of combs are located towards the finger. The dimensions of the finger ensure engagement of the protrusions of the selected number of metal plates of the cargo foot and their fixation in the grooves of the combs.
