The invention relates to the technical equipment of sports facilities and is intended for training with a barbell.

The aim of the invention is to ensure safety and convenience in use.

FIG. I shows the device, a general view; in fig. 2 - front view holders and locks, placed in racks; in fig. 3 - the same, side view.

The device contains two racks 1, a base 2, two holders 3 rods, two movable rods 4, two return springs 5, two restricting washers 6, two support plates 7, two blocks 8, two locks 9, including two shoulders, angular levers, cables 10 and II, two mounting brackets 12.

The rack 1 is made of a pipe in which the holder of the rod 3 is placed, the movable rod 4, the return spring 5, the support plate 7, the block 8, the lock 9, the cables 10 and And, the clamp 12, and has an arched shaft 6 in the upper part 6 shaped holders 3 shtangi with a hole for the rod 4.

The base 2 is made of a pipe, serves to connect the racks 1 between them, accommodate cables 10 and 11 in the cavity, and has an arched shape. The holders 3 of the rod are made in the form of a concave surface and serve to place a bar of the neck on them.

The movable rod 4 has a stepped shape formed by two cylinders of different diameters, and the diameter of the upper part of the movable rod 4 is larger than the diameter of the lower part. The movable rod 4 is located in coaxial holes 11: ibs 6 and the support plate 7. The upper Topeii of the movable rod 4 is rigidly connected to the holder 3 of the rod, and the lower - with the unbranched end of the cable 10 or 11.

The return spring 5 rests against the upper end of the movable rod 4, the lower end against the support plate 7 and serves to reset the movable rods 4 and the holders 3 of the studs.

The washer 6 is fixed in the upper part of the uprights 1, has the shape of the holders 3 of the rod, and a guide hole for the movable rod 4 is made in it.

The support plate 7 has a guide hole for the movable rod -;:, is a support for the return spring 5 and the fixing point of the block 8.

The block 8 is secured in a slot on the support plate 7 on the opposite side of the lock 9 and guides the movement of the unbranched end of the cable 10 or 11.

The upper ends of the levers have bent outwardly 1 bars and a contact for the bar; contact with the holder is 3 bars.

To; 1; by the ends of the levers of the lock 9 are attached p;} the branded ends of the cable 10 or 11. Lock 9 is intended for fixing the bar of the rod on the holder.

The cable 10 is unbranched end mounted on the movable rod 4. Through the block 8 of the first rack 1 the second branched end of the cable 10 is fixed to the levers of the lock 9 of the second rack 1. And the second beater of the cable 10 is branched by the number of levers of the lock 9, each branch of which is attached to one lock lever 9. Branching begins at the level of the bracket 12 of the second pillar 1.

Similarly, the cable 11 with its ends is fixed on the levers of the clamp 9 of the first rack 1 and on the movable rod 4 and covers the block 8 of the second rack 1.

The fastening brackets 12 are fastened to the inner wall of the uprights 1, are at level 5 of the branching of the ends of the cables and serve to guide their movement.

The device works as follows.

After the exercise, the bar is lowered onto the village. 3 bars of the pillars 1. Under the weight of the bar, the holders 3 0 of the bar and the movable rods 4 are lowered all the way onto the limiting washers 6. The return springs 5 abutted with the upper ends of the movable rods 11 and 4 and the lower the support plates 7 are compressed. The cable 10 5 moves along the block 8 inside the racks 1 and the base 2 .. with the movable rod 4 of the first rack and, passing through the fixing bracket 12, closes the lock 9 on the second rack 1. The cable 11 is loose, ATS on the block 8 inside the racks and the base 2 behind the movable 0 rod 4 of the second rack 1 and, the passage through the mounting bracket 12, closes the lock 9 on the first rack 1.

When changing the weight at one end of the i-reef rod, the lighter end of the rod tends to lift, i.e., the bar overturns. 5 The levers of the lock 9 prevent tipping over with a force equal to the weight of the opposite end of the rod, as the holder of the rod 3, which is lowered under the action of the weight of the rod, rotates through the shaft: 4 and the cable keeps the lever 9 of the opposite rack 1 closed. polohchenii.

When the boom is removed from the holders of the 3 boom, the return spring 5, expanding, pushes the movable rod 4 with the holder 3, and the ptangi follow the boom. The holders of the 3 rods open the levers of the lock 9.

If the pin. placed on the holder 3 of the rod: so that its one end presses on the holder 3 of the rod, and the other does not, the levers of the lock 9 opposite (not bearing the load) rack 1 do not close, because 0 abut against the holder 3 of the rod.

Equipping the legs with locks allows you to securely hold the bar on the holders from tipping over at the moment the load is changed at one end of the neck and does not prevent the bar from being removed from the holders. /five
