SELF-LOCKING FENCE OF A FEEDING TABLE Russian patent published in 2018 - IPC A01K1/06 A01K5/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the improvement of self-locking fences of the feed table. Self-locking fence of the feed table comprises at least one swivel bar (1), two vertical crossbars, upper rail (3), lower crossbar and locking mechanism (L). Upper rail (3) and lower crossbar are installed in parallel and are connected by vertical crossbars to form an aperture, in which at least one swivel bar (1) is movable from open position (P1) to form an upper aperture to locked position (P2) to form a closed upper aperture. In this way, it is possible to move at least one swivel bar (1) back to said open position (P1), as well as the possibility of locking and unlocking at least one swivel bar (1) in the locked position (P2) by means of locking mechanism (L). Locking mechanism (L) comprises at least one latch (7), one release slider (8) and latch drive element (5) movably mounted on upper rail (3). Release slide (8) is rigidly attached to drive element (5) of the latch. Latch (7) comprises locking part (7a), unlocking part (7b) and inclinable part (7c). Locking part (7a) of the at least one latch (7) is configured to block at least one swivel bar (1) in the locked position (P2) and interact with release slide (8). Also at least one unlocking element (11) is provided, in contact with unlocking part (7b) of at least one latch (7). Unlocking element (11) has the form of a push-button switch having, at its lower end, pressing part (11a), in contact with at least one latch (7) and attached to latch drive element (5) which is movably mounted on said upper rail (3). Moreover, pressing part (11a) is configured to contact with unlocking part (7b) of at least one latch (7).

EFFECT: invention provides ease of use due to a smaller number of fencing components and the absence of loose components.
