Description

The invention relates to sports equipment for training on the street and at home, namely, power simulators for the development of the muscles of the hands, shoulder girdle, back and press.

There are a significant number of horizontal bars installed in the opening. Known analogue [1], made in the form of a tubular bar, equipped at the ends with spindles with centering holes. The spindles are supported by the conical protrusions based on the mounting means.

In the case of the analogue [2], the tubular crossbeam is fixed to the L-shaped brackets with the help of connecting bolts.

There is an analogue [3], where the tubular crossbeam, flattened at the ends, fits into the brackets fixed to the door frame, in the corresponding slot grooves of the brackets.

Mentioned analogues have a common disadvantage associated with the width of the opening in which they can be installed. The analogue [3] assumes a fixed crossbeam size. Analogs [1] and [2] have the ability to adjust the size of the horizontal bar, but in a small range. The adjustment range for the analogue [1] is limited to at least the long travel of the spindles. The adjustment range of the analogue [2] is limited by the combination of segments between the holes on the crossbar for connecting bolts. In other words, the considered analogues do not have universality with respect to the size of the opening at the installation site. The unknown width of the opening involves the manufacture of horizontal bars of different sizes into standard openings, for example, doors and corridors or the manufacture of a horizontal bar to order for the size of the selected opening.

As a prototype of the invention, an analogue [4] was chosen as the closest in technical essence and the achieved result. The removable horizontal bar [4] consists of a round crossbeam with a profiled end, with supporting parts in the form of plates.

The disadvantage of this horizontal bar is the difficulty of installing the support plates on some types of support surfaces and the lack of adjustment of the position of the plates. According to the installation conditions, holes for the crossbar with a larger diameter than the diameter of the bar of the crossbar must be made in the supporting surfaces. This is a large enough size for holes made without professional equipment and accessories.

For a wooden supporting surface, holes are prepared quickly with specialized tools, such as hand drills and large diameter drills. Holes in brick or concrete are made longer and special, rarer and more expensive tools may be required, such as nozzles for drilling holes in large diameter concrete. The same can be said about the metal supporting surface, if, for example, it is necessary to install a horizontal bar in the opening of a metal door. A special drill or milling cutter may be required. The holes can be made in different ways, but the lack of a suitable tool complicates the installation and increases the installation time.

In addition, when installing the horizontal bar, defects and roughnesses of the supporting surfaces in the selected place, preferred for installation, can be detected. In this case, the support plates, judging by the proposed design, should be skewed, which may make it impossible to lay the crossbar in the support plates or affect the bearing capacity of the support plate due to the occurrence of undesirable torque when loading on the crossbar.

The invention is aimed at eliminating these shortcomings and providing a simpler and more efficient technology for installing the horizontal bar on the supporting surfaces of various types, with the possibility of adjusting the position of the supporting parts, as well as creating a universal horizontal bar design that can be installed in any opening with suitable supporting surfaces, the width of which less than the length of the manufactured horizontal bar.

This is achieved by the fact that in the design of the universal horizontal bar the supporting parts for the crossbar are installed with a gap to the supporting surfaces due to the installation of a set of washers-gaskets between the supporting surface and the supporting part, which can be adjusted in quantity or size, and the size of the horizontal bar can be determined at the time of installation depending from the width of the selected opening.

The figure 1 presents the installation diagram of the horizontal bar in the opening. The crossbar 1 is inserted into the supporting parts 2 and 3, which are fixed by fastening elements to the supporting surfaces with a gap through a set of washers-gaskets 4.

The figure 2 shows the supporting parts 2 and 3 with holes of round and oval shape. An oval hole is necessary to prevent the horizontal bar from spinning around its axis during classes on the crossbar. A round hole allows the use of a crossbar of arbitrary longitudinal size if its length is greater than the width of the opening at the installation site.

The horizontal bar can be installed in any opening on the street and in the building where there are suitable supporting surfaces that can withstand the load: openings of wooden and metal doors, concrete, brick, plaster walls of corridors, passages between buildings, poles.

The universal horizontal bar in the opening consists of a cylindrical crossbeam 1 with an oval-shaped end and two supporting parts 2 and 3 with holes for a round and oval-shaped crossbar and holes for fastening elements. When installing a universal horizontal bar, the crossbar 1 is cut from the side of the circular end exactly to the size of the width of the opening and is installed in the supporting parts, fixed with a gap to the supporting surfaces through a set of washers-gaskets. If necessary, to compensate for the unevenness of the supporting surfaces, when installing the supporting parts, washers of different thicknesses or a set with a different number of washers are used so that the supporting parts are installed vertically and in parallel.

As a prototype, we used a metal pipe with a diameter of 28 mm, a length of 1500 mm, crimped at one end, and metal supporting parts with a thickness of 10 mm with a hole for a round crossbeam with a diameter of 30 mm and an oval shaped hole for the size of the compressed end of the pipe. In the supporting parts, holes were made for the fastening elements. The universal horizontal bar was installed on the concrete walls of the corridor with a width of 1200 mm. But could equally well be produced in any corridor of a smaller and a larger size. Determining was the length of the pipe. The pipe was cut from the round end to the opening size of 1200 mm and installed in the supporting parts, fixed with dowels and screws at a height of 2100 mm on the concrete walls of the corridor opposite each other. A hand drill and a drill bit for concrete with a diameter of 8 mm were used for installation. A metal hacksaw was used to trim the pipe. The supporting parts were installed with a gap of 6 mm to the walls and were aligned in the vertical plane due to a set of M6 metal washers. The compressed end of the crossbar was placed in the oval hole of the support part, and the round one was placed in the round hole of the support part located opposite the first. When installing the screws were passed through the washers.

With a sufficiently large crossbar length, the universal horizontal bar in the opening can be installed in most standard openings with suitable supporting surfaces.

Thus, the design of a universal horizontal bar in the opening was created, which does not require the manufacture of large diameter holes in the supporting surfaces, with the possibility of adjusting the position of the supporting parts, and it is possible to install the horizontal bar in openings with suitable supporting surfaces, the width of which is less than the length of the manufactured crossbar. The installation technology of the horizontal bar has been greatly simplified.
