Lock which can be opened and closed on opposite sides - Las som kan öppnas och stängas frän motsatta sidor

The present invention relates to a lock mounted on the upper edge of doors, in particular sliding doors, which can be opened and closed on opposite sides and consists of a lock body (1), a lock pin (2), a lock actuating lever (3) ) a transverse pin (9) is located, and a pivot axis (4) having a channel (15) for the lock pin (2) in the lock body (1).

10 For safety and operational purposes, sliding doors and the like for general use must be capable of locking and unlocking the door from both sides of the door simply and reliably. In addition, it is desirable that the structure of the lock is as small as possible and that the lock as a whole is narrow so that it can be easily and discreetly mounted on the door.

It is an object of the present invention to provide a lock which is simple in its construction and reliable in operation and can be opened on either side of the door by a key suitable for the lock.

The lock according to the invention is characterized in that the locking pin has an elongated notch at the inner end of the body with a transverse pin housing the free end of the lock actuating lever, one end of which is pivotally connected to the lock body by a rotary axis , is shaped according to the lock key, and that the lock pin has two transverse grooves for the locking means, the recesses of which have a mutual distance corresponding to the displacement of the locking pin between the locking position and the unlocked position.

30 To secure the locking and unlocking position of the lock, the locking pin is provided with two transverse grooves into which the locking member of the lock, preferably a spring-loaded ball member, presses into the locked or unlocked position of the pin and secures the pin.

The body is slit and thus consists essentially of two parts. The distance between the parts can be adjusted by means of a screw between them.

The invention will be described in more detail with reference to the accompanying drawings, in which Figure 5

Figures 5 and 6 show the axis of rotation of the lock from the end and from the side,

Figure 8 shows the lock pin.

The lock according to the invention consists of a rectangular planar body 1 with a gap extending almost the entire body. At the other corner of the body piece 25 is a piece connecting the pieces (shown in Figure 1 and 2 as a dashed area in the upper left corner). Near the other edge of this lock body 1 is a channel 15 of circular cross-section; for the dedicated lock pin 2. An elongated notch 8 extends from the lower end of the lock pin 2 with a transverse pin 9 at its lower end to two free ends of the lock actuation lever 3 formed by a groove 7 at the end of the lever 3, secured to the pivot axis 4, which, in turn, is pivotally mounted on the lock body 1. At each end of the shaft, in the embodiment shown, there is a triangular pin portion which is free on the favorite sides of the body 103357 3 and is intended for a corresponding shaped key. In this way, the pivot lever can be operated on both sides of the lock.

The locking pin 2 also has two transverse grooves 11. When the locking pin 2 is in the extended position 5 (Fig. 1), a spring-loaded locking member 12 (Fig. 3) is pressed into the lower groove 11 to hold the pin in its upper locking position. In the retracted position (Fig. 2), the locking member 2 protrudes into the upper locking groove of the pin, thereby holding the pin in its retracted position.

10

The operation of the lock can be adjusted by changing the slit width with the screw connecting the frame members 10.

The lock is assembled by placing the operating lever 3 in a slot 1 in the lock body 1. In the grooves of the operating lever 3, a hexagonal hole is made in the end, which hole is located at the hole made for the pivot lever 1 of the lock body. A rotary shaft 4 having triangular projections at both ends and a hexagonal flange in the center of the shaft is disposed in a hole in the body 1 so that the hexagonal flange 5 protrudes into the corresponding hole in the operating lever 3 therefor.

Above the axis of rotation 4, a spring 12 acting as a spring-loaded locking member 12 is disposed in the bore 15 of the locking pin 2, which is made obliquely towards the housing. This hole extends further through the housing and into which a screw 10 is secured. the distance between the parts can be adjusted.

A locking pin 2 is disposed in the channel 15 so that the free end branches of the operating lever 3 are located on either side of the transverse pin 9 of the slot 7 in the pin 2.

30

The bearing pieces 13, which are threadedly attached to the lock body 1, are dimensioned such that the outer portion of the hole 14 in the central portion thereof is larger in cross-section than the inner portion of the lock body 1. Through this bore 14, the end of the pivot axis protrudes so that the triangular pins remain visible. Due to the extended outer part of the hole 14 103357 4, there is sufficient space around the pins 6 of the pivot shaft 4 to insert the key over the ends of the pin to rotate the pivot shaft while simultaneously opening or closing the lock.
