Description

The invention relates to training devices for exercises simulating a game of table tennis, contributing to physical development and coordination.

Known devices for exercises that simulate a game of table tennis: "Wheel with TSP SPIN-RAD mount" [1], mechanical simulators for table tennis "Handicap Vector" and "Vector" [2], "Training device for table game exercises tennis ”[3].

The closest is the device [3], containing a clamp with a platform for attaching to the table, a stand, a freely rotating wheel located in the earring spring-loaded relative to the stand with a smooth rod that can move in the through hole of the stand with a thread into which the threaded rod of the second earring is screwed secured with screws to the clamp rib in the form of a semicircle in the radial and central holes of the rib.

The disadvantage of this device is the complexity of the design, which adversely affects the complexity of manufacturing and changeover time when changing the type of exercise.

The technical result of the invention is to improve the device to reduce the complexity of manufacturing and reduce readjustment time when changing the type of exercise.

The technical result is achieved due to new elements and their new connections in the training device, namely: a device containing a clamp with a platform for attaching to a table with an edge with central and radial holes, a rack located in the earring spring-loaded relative to the rack, a freely rotating wheel, and the rack has a slot or flange with holes for fastening with screws to the radial and central holes of the clamp ribs, a spring tightly fitted with one end to the free end of the rack and rigidly connected second end with earring wheels. Moreover, the earring of the wheel may have a smooth rod with the ability to move in the through hole of the rack in the form of a pipe with a threaded rod that is rotated in the angle and screwed into the rod in the longitudinal groove of the rack. Ease of displacement and return of moving elements is achieved by spring selection.

A change in the position of the wheel in space is achieved by changing the radial hole for the screw in the edge of the clamp and turning the end of the spring tightly mounted on it, including changing the angular location of the threaded pin that is embedded in the smooth shaft of the earring.

Figure 1 shows the proposed device.

The device consists of a soft, preferably rubber, hollow toroidal wheel 1 located in an earring 2 made of lightweight material spring-loaded relative to the stand 5, the clamp 7 with a platform for attaching to the table and with an edge with central and radial holes, and the stand 5 has one end a slot or flange with holes for fastening with screws 8 to the radial and central holes of the ribs of the clamp 7 and has the form of a pipe, a spring 3 is tightly mounted on its other end, rigidly connected to the earring by the second end 2 wheels 1. At the same time, the earring 2, in order to give linearity to the longitudinal movement of the wheel relative to the rack, can have a smooth rod 4 moving in the longitudinal hole of the rack 5, into which a removable threaded pin 6 sliding in the longitudinal groove of the rack 5 is mounted to fix the angular position of the wheel 1 relative to the rack 5 .

The device operates as follows. When a racket touches a soft wheel 1 or another, the wheel, rotating from the impact in the earring 2 and moving together with the spring-loaded earring 2 relative to the rack 5, instantly bounces off the racket, making the tracking time of the wheel 1 racket minimal due to the sufficient travel and ease of displacement of the low-inertia earrings 2 with the wheel 1 and the softness of the spring 3. At the same time, the racket has the ability to continue the further movement inherent in the table tennis technique, and the wheel 1 is returned by the spring 3 to its original position. A smooth rod 4 moves in the longitudinal hole of the rack 5, screwed into the rod 4, the threaded pin 6 moves in the longitudinal groove of the rack 5 and determines and fixes the angular position and longitudinal movement of the wheel 1 relative to the rack 5 by its angular and longitudinal position in the rod 4.

The technical result of the invention, which consists in improving the device, reducing the changeover time when changing the type of exercises and reducing the complexity of manufacturing, is achieved by reducing the total number of parts, including those subject to changeover.
