The subject of the invention is a partition and a device, intended specifically for callisthenic exercises, and a set comprising of a partition with a device, intended in particular for callisthenics with a variety of applications, mainly for training the entire body, which allows even development of larger muscle groups and has a positive effect on improving physical fitness.

There are many devices and instruments utilized mainly in weight rooms, used to build strength endurance using just own body weight.

As a rule, known devices or instruments are aimed at performing a specific type of exercise and they cannot be reconfigured in such a way that they can be used to exercise other parts of the body without additional attachments. However, such a great number of specialized equipment requires an adequate space, which, even in the case of a weight room, is a big accommodationspecific and logistic challenge. Nowadays, more and more people give up exercising at the gym and stock up on specialized equipment for weight exercises in their apartments, dealing with bulky and unsightly, oversized at times, equipment.

Each of the mounting U-channels 4 and 6 consists of an element with a U-shaped profile, both ends of which are blanked off with double-sided locking elements 14, having a rectangular plate-shaped element 15 adjacent to the faces of this strip, and an internal washer face 16 embedded inside the strip, while the upper ends of the washer faces 16 have two threaded holes 17 for metric thread socket head cap bolts 18, while the horizontally located bottom of the mounting U-channel 4 and 6 has through holes 19, evenly spaced along its length, for mounting screws 20, and located underneath it on the bottom, rectangular rubber washers 21 placed between these strips and the floor 22 and the ceiling 22’ of the room. Mounting U-channels have a length of I = 820 mm and a width of T = 60 mm and are made of stainless steel.

The method of assembling this partition from panels made in such a way consists in the fact that the mounting U-channels 4 and 6 are screwed by means of screws 20 via through holes 19 made in their bottoms and rubber washers 21 placed under their bottom to the floor 22 and ceiling 22’ of the room at a distance from its walls allowing free training both on one side and on the other side of the partition, and locking elements 14 are screwed on one side of the mounting U-channels 4 and 6, and then the panels 1 and 2 are inserted, respectively, so that the panel 2 is pushed against the panel 1, whereas in the groove 13 of the panel 1 the grooves 8 of the panel are inserted, and the trapezoidal recess 11 of the panel 1 together with the corresponding trapezoidal portion of the recess 9 of the panel 2 forms an elongated through hole 23 with a length L = 400, and then the panel 1 but this time rotated by 180° is inserted into the panel 2, and as a result of this an elongated through hole 24 with a length of LI = 1000mm is formed between the panels thus connected, and then into this panel yet another panel 2 is inserted, as a result of which an elongated through hole 23 ’ is formed between these two panels at the bottom portion of the partition, and then another panel 2 is inserted into panel 2, but this time rotated by 180°, as a result of which an another elongated through hole 24 is formed, and then another panel 1 is inserted into the rotated panel 2 forming an elongated through hole 24’ located at a distance of D2 = 530 mm from the lower end 5 of that panel, and then another panel 1 rotated by 180° is inserted into and as a result, another elongated through hole 23 is formed between the panels so connected, as a result of such a connection of four panels 1 with their shorter profiled recesses 11 and three panels 2 with their longer profiled recesses 11 , three shorter, of the same length, through profile holes 23 and 23’ were formed and three longer, of the same length, profile through holes 24 and 24’, whereas the upper ends of the two profile through holes 23 are located near the upper ends 3 of the panels 1 and 2, while the lower end of the third profile through hole 23’ is located near the lower ends 5 of the panels 1 and 2, and the profile through holes 24 face each other and their upper ends partially overlap beyond the lower ends of the profile through holes 23 and their lower ends partially overlap beyond the upper end of the profile through opening 24’, the lower end of which partially overlaps beyond the upper end of the profile through opening 23’, and furthermore between the seven panels 1 and 2 thus connected to each other under and a decorative, blind rectangular channel 25 is formed over the holes 23, 23’, 24 and 24’ over the entire height of these panels. After the seven panels 1 and 2 have been assembled this way, the opposite ends of the mounting U-channels 4 and 6 are secured with locking elements 14.

Example 2 The partition according to the second embodiment of its design is shown in Fig. 22-29 is similar to the partition according to the first embodiment of its design, and the difference between them lies in that in the latter embodiment, the partition consists of ten panels 1 and 2 connected with each other by means of a tongue-to-groove joint placed in the mounting U- channels 4 and 6, the assembly method of which is similar to that described in example 1, where the 180° rotated panel 2 is pushed against panel 1, and the consecutive panel 2, into which another panel 1 rotated by 180 ⁰ is inserted, which connects with the analogously rotated panel 2, and then panel 1 is inserted connected to panel 2 rotated by 180°, to which panel 2 is connected, to which the panel 1, rotated by 180°, is connected with yet another panel 1. As a result of such combination of panels 1 and 2, including four panels 1 with their shorter profiled recesses 11 and six panels 2 with their longer profiled recesses 11 ’ forming four shorter profile through holes 23 and 23 ’ of the same length and five longer profile through holes 24 and 24’ of the same length, the upper ends of two opposing profile through holes 23 located near the upper ends 3 of panels 1 and 2, while the lower ends of the two remaining profile through holes 23’ are located near the lower ends 5 of panels 1 and 2, while the through profile holes 24 are placed opposite each other with their upper ends partially overlapping beyond the lower ends of the profile through holes 23 and their lower ends overlap partially beyond the upper ends of the three profile through holes 24’, the lower ends of which partially overlap beyond the upper ends of the profile through holes 23’. As a result of such a connection of panels 1 and 2, a decorative, blind rectangular channel 25 was formed between these two panels.

In this design embodiment, the mounting U-channels had a design similar to that of the mounting U-channels described in the first example, and their length was I = 1320 mm and they were made of metal.

In further design embodiments of the partitions according to the invention, their panels 1 and 2, not shown in the drawing, had a height of H = 2500 or H = 3500 mm, a thickness of G = 70 mm and a width of S = 170 mm, and the length of the mounting U-channels was adjusted to the number of panels 1 and 2 installed in them, whereas the upper ends of the holes 23 being located respectively at a height Hl = 2400 mm to 3200 mm from the ground 22 of the room and the lower ends of the openings 23’.

It is obvious that the partition according to the invention may consist of two panels 1 or two panels 2 or any number and combination of panels 1 and 2, and its length and width are adjustable to the needs of its users.
