SU10244A1 - Horizontal bar - Google Patents

Description

In the proposed gymnastic horizontal bar, in order to eliminate accidents, when performing the folding And dangerous gymnastic exercises, a safety net is inserted, which can be rotated from the motor OR from the handle through the FRICTION AND gear system, and stopped at the right

jviOMeHT using brake assist devices.

The drawing shows the horizontal bar side view. The fi racks 1, 2 reinforce the pole 3, into the right end of which a check 23 is inserted, not allowing the pole to rotate, and the left end enters the sleeve 4 rotating in the bearing 5. The lanes 6, 6 are suspended one directly; to the pole 3, and the other in the sleeve 4, movably connected to the strips 7, the ends of which are fastened by a transverse strip 25, form a frame. The grids 8, 9 and 10, tightening on the frame, form a safety net, the length of which can vary by moving the strips 7 relative to the strips 6, due to the presence of slots in the first ones. The disk 24 of the sleeve 4 is frictionally coupled to the DISK 11, SEATING on the shaft 12,

which rotates in bearings 26; the shaft 12 borrows rotation from the motor 16 OR from the handle 15 through a pair of bevel gears 14, 13. The speed of rotation of the grid is controlled by moving the disk 11 relative to the center of the disk 24 using the handle 19, the SCREW spindle 18 and the FORK 17. Lever 20 rotating around the AIS 27 serves to bring in contact the end surface of the tide 22 on the hub 4 with the same surface of the tide 21 on the bearing 5; Due to this, during rotation, three-injected surfaces occur, and the safety net, reducing the rotation speed, can be completely stopped (slowed down).

When performing a difficult exercise, for example, “the sun is taken by hands on pole 3 and leaning its heifers to the safety net, the latter is informed by rotation from the motor 16 OR from the handle 15. The safety net rotates it around the pole 3 AND the moment that can occur under the action of centrifugal force and weight, the separation of the gymnast from the horizontal bar, it will keep him from falling.

.Peddet patent.

1. A turner that differs in using mesh B ,, 10, freely suspended on a pole 3 by means of lanes 6-7, br-7 and driven into compulsory rotation from the friction disk 24 and driven from the motor 16 or I of the handle 15 of the disk 11,

2. At the application specified in para 1 of the horizontal bar, to regulate the movement of the disk 11 along the shaft 12

grid speed 8, 9, 10, with a motor drive-screw stem 18 with a handle 19 and a fork covering the neck on the high tide of the disk 11.

3. The form of execution of the horizontal bar specified in subsection 1, 2, characterized in that the following are intended to switch off the friction drive and to slow down the rotation of the grid 8, 9, 10: a) tide 22 on sleeve 4 and b) lever 20, input one end into the recess in said sleeve.
