SU35605A1 - Springless lock - Google Patents

Description

Known spring locks with pivot on the axis of the bolt. In such a springless lock, it is proposed to make the bolt in the form of a box freely rotating on an axis fixed on the part of the lock screwed to the door panel.

In FIG. 1-4 show the details of the lock; FIG. 5 and 6-lock in closed and open position; FIG. 7-side view of the castle; FIG. 8 - details of swivel washers; FIG. 9 is the finished key and the plate from which it is made, and Fig. 10 explains how to attach the lock to the door panel.

The proposed springless lock consists of a stamped box 2 (Fig. 1, 2) made from a plate I (for example, a 2 mm material) and provided with a slot for placing two or three shields 4 on the edge of the box (Fig. 6 , eight). Gaskets are inserted between these washers 4 to prevent the washers from touching each other. To hold the washers 4, the pads 7 of the box 2 bent inwards serve. The box 2 with the washers 4 is a lock bolt and is attached pivotally to the plate 3 by gluing 8 (Fig. 3, 10). The very same plane (164)

The string 3 has curved edges 5 and 6 (Fig. 4 and 7), between which the box-edge 2 passes during rotation. To rotate the washer 4, a pressed key 10 (Fig. 9) is inserted into the hole 11, which, having entered its engagement with the stops 12 of the washers 4, gives them a different position (Fig. 8).

In addition, in the washers 4 there are curved notches 13, which when turning the washers 4 go on the fixed protrusion 6 of the plate 3, thanks to which it is possible to put the box dowel 2 in such a position that the lock will be opened (Fig. 6) and then closed (Fig. 5), for which the box-bolt 2 is moved to the left, with the angle 15 of the box 2, entering the corresponding larva, closes the room (Fig. 5); then the key 10 is rotated, the high edge of which places the shields 4 so that the stops of their 12 become in one position, and the cuts 13 diverge and receive different directions (Fig. 8), in which the bolt rotation in the opposite direction becomes impossible, since the outer edges of the washers 4 abut against the protrusion 6.

To turn off the lock from the action, the lock box-lock must be inserted.

In FIG. b and 10, which is achieved by turning to Y.ch in the opposite direction, and the key sets the washers 4 to the position shown in, Fig. 6, in which the stop 6 is free to pass through the notches 13 of the washers; This is a rigel that, under the influence of its weight, takes a position on. FIG. 10. Plate 3 is attached to the door with screws 18, the heads of which, when locked, are closed by a box 2.

The present invention; A springless lock using a bolt rotary on the axis, characterized in that bolt 2 is box-shaped, comprising washers 4 pivoting on the axle with slots 13 for passing the fixed protrusion 6 and stops 12 for the corresponding shaped parts of the key 10 to be mounted washers 4 in one or another desired position.
