Description

The invention relates to sports, in particular to means for training weightlifters.

A well-known sports bar comprising a bar, load disks mounted on it by means of bushes, and means for fixing the disks on the sleeve.

The disadvantage of the prototype is that during the exercise the athlete cannot independently change the weight of the barbell.

The aim of the invention is to increase the effectiveness of training.

In FIG. 1 shows a bar, general view; in FIG. 2 - additional cargo disk.

At each end section of the bar neck 1 there is a sleeve 2 with a shoulder and with the load disks 3 installed on it and means for fixing them on the sleeve, made in the form of a nut 4 (or by any other known method). A washer is fixed from the end of the neck 5. A load disk 6 with a radial slot is installed between the washer and the end of the sleeve for passing the bar neck (Fig. 2). The sleeve has a

a longitudinal through hole 7 in which a slotted disc lock is located. The latch is made in the form of a spring-loaded pin connected by a rod 9 with a pressure angular lever 10 placed on the side of the collar of the sleeve. The slotted cargo disc has an opening 11 for engaging a spring pin therein.

The bar is used as follows.

The discs 3 are put on the sleeve and secured with a nut. Then, the radially slotted disk is mounted on the neck, by pressing the lever, the pin is inserted into the hole of the sleeve, and the disk is turned with the slot until the holes of the sleeve and disk c are aligned. slot, then release the lever and the pin enters the hole in the disc with a slot. The bar is ready to go.

about

After the athlete has exhausted his strength, and can no longer lift the barbell. he gnaws at its lower position and presses the levers with his fingers, as a result of which the spring-loaded pins come out of the cargo holes with a slot, and the disks slide off the bar under the influence of their own weight. After that, the athlete performs several more movements.

The proposed sports bar allows the athlete to train without the aid of assistants, facilitates exercise and reduces training time.
