IMPLEMENTATION OF THE TECHNICAL SOLUTION

[0022] Fig. 1 shows the general principle of using the clamp (200) of the power band (103). One or more clamps (200) (depending on the type of exercise) are installed in the openings (104) of the power frame (100). As a rule, most models of power frames (100) have openings intended for various types of additional equipment. The example shown in Fig. 1 demonstrates the use of clamps (200) for performing squats with a barbell, in which the power band (103) is fixed with one end to the barbell (101), and the other is attached to clamps (200) placed on both sides in the lower openings (104) of the frame (100). The clamp (200) can also be placed on the upper beams and/or side posts of the frame (100), depending on the type of exercise.

[0023] As shown in Fig. 2A-2B, the design of the lock (200) is made of two parts (210, 220) that form a receiving (210) and a mating (220) part, which are connected to each other. The lock (200) is preferably made of metal, for example, steel. The connection of the parts (210, 220) is carried out with the help of an element (224), which ensures the retention of the mating spring-loaded part (220) with the help of a splined connection inside the sleeve (212) of the receiving part, as well as a spring limiter (227), held by at least two fastening elements (215) on the sleeve (212), thereby ensuring the movement of the tail part (225), on which the spring (226) and the end part (228) are placed. Bolts, screws, screws, push-button clamps, etc. can be used as fastening elements.

[0024] Fig. 3 shows a view of the receiving part (210), which is made in the form of a sleeve (212) at one end, which is connected (for example, by welding or a threaded connection) to the tail part (211). The tail part (211) contains a thread that ensures the fixation of the retainer (200) in the opening of the load frame using a nut (213). Additionally, one or more washers (214), for example, metal or plastic, can be used to improve the clamping with the profile of the load frame.

[0025] The bushing (212) has a preferably circular cross-section with a square cross-section section (216) forming a cavity for accommodating the element (224) therein. In a particular embodiment, the bushing (212) may have a completely square cross-section and be made rectangular. The bushing (212) contains openings in which fastening elements (215) are placed, ensuring the retention of the spring limiter (227) on the bushing (212).

[0026] The tail section (211) is cylindrical and may be a stud or bolt. The bushing (212) may be made from a square section profile, for example, a square steel pipe. When making the bushing (212) of a circular section, an additional internal square is machined into its internal cavity to form the cavity (216).

[0027] Fig. 4 shows an example of the execution of the counter part (220), which is made in the form of a part containing a tail part (225), made in the form of a cylindrical body, which is connected to the head part (221), containing a slot (222) for placing a power tape in it.

[0028] Additionally, a limiter (223) of the power tape can be made on the head part (221), which, as shown in Fig. 5, contains a housing (2231), welded or connected by means of a threaded connection with the head part (222), a rod (223) in the form of a pin or rod, on which a spring (2232) is placed inside the housing (2231), ensuring the movement of the rod (223).

[0029] The tail part (225) contains a spring (226) which ensures that the mating part (220) is pulled out of the receiving part (210) by a given stroke of the spring (226), which rests with one end against the spring stop (227), fixed on the sleeve (212), and with the other end rests against the end element (228).

[0030] As shown in Fig. 6, this principle of connecting the parts (210, 220) of the lock (200) allows for quick adjustment of the tension of the power tape placed in the slot (222) by pulling out the part (220), turning it at a given angle along the circumference with a stroke of 90° and then installing it back into the receiving part (210). By using the spring (226), a convenient principle of adjusting the tension of the tape is realized.

[0031] The power band (103) is placed in the slot (222), which is preferably made rectangular in shape. To adjust the tension of the band (103), the mating part (220) is rotated clockwise or counterclockwise, providing the required tension of the band (103) and is inserted into the sleeve (212) of the receiving part (210), held in place by the tension of the spring (226).

[0032] The diameter of the cylindrical part (211) of the receiving part (201) is selected based on the dimensions of the openings (104) of the power frames, with the calculation that the diameter of the sleeve (210) of the receiving part must be larger than the diameter of the tail part (222) of the mating part, in order to ensure tight contact and fixation of the parts (201, 202).

[0033] The receiving part (210) can be made in the form of a single cast product or represent two parts connected together (for example, by means of a thread), containing a cylindrical part (211) and a sleeve (212).

[0034] The slot (222) may contain internal projections, as presented in Russian Patent No. 232722, which make it possible to eliminate the possibility of horizontal displacement of the tape (103), and thereby prevent the possibility of the tape (103) jumping off the retainer (200). In another particular embodiment of the retainer (200), one or more external projections may be provided, providing additional retention of the tape during its winding, preventing it from jumping off.

[0035] The initial installation of the retainer (200) may take place as follows:

placing the barbell on the stops (102) and placing the required weight on the bar (101);

installing the clamps (200) in the required position by placing them in the holes (104) of the frame (100);

placing the tapes (103) on the barbell handle (101) and the slots (222) of the clamps (200);

pulling out the mating parts (220) with the tape (103), winding the tapes to the required resistance force by turning the mating part (220) clockwise (or counterclockwise), positioning the element (224) in the cavity (216) of the sleeve (212) and releasing the mating part (220), which returns by stretching the spring (226).

[0036] The use of the retainer (200) can increase the effectiveness of the training process and be used for various types of exercises, providing variability in regulating the load exerted by using the power bands (103), without the need to change the type of bands to others with an increased rigidity index.
