SU19964A1 - Door lock with a lock placed in the outer door handle - Google Patents

Description

The proposed door shutter, with a lock placed in the outer door handle, is intended to provide such an arrangement where the shutter can be used on both sides of the door for closing and opening, and if desired, leaving it inactive. When the shutter is opened, both knobs can operate freely or only one of them is released, while the other remains in the closed position. You can then close both knobs, putting them into complete inactivity, so opening the shutter becomes impossible.

Device for actuating the proposed door shutter can be installed in the opening shutter position, closing and doubly closing position.

In FIG. 1 shows a longitudinal section of a device installed in a door; FIG. 2 is a section along line 11-11 of FIG. 1, and FIG. 3 is a top view of a cylindrical valve and parts connected to it.

The door has a drilled hole 6, with strip 7 on it being riveted on the inside. the rotating rod 8 of the door handle 9 is placed. This handle is fixed by screwing and using a set screw P on the tubular part 12. The pipe part 12 is inserted into the drilled hole 6 and provided with an expanded part 13 having an external screw thread 14 and rotatable screw connection with the rod 16 outer handle 17.

The end 13 is provided with slots 18 and 19 spaced diametrically against each other, having beveled running sides 21 and 22, which are connected with slots 23. In the case of pin 16, there are the same slots 24 covering the slots 23. Inside the door handle 17 and the core of its 16 is arranged with a key lock 26, having a locking device, which has a locking position every quarter of a turn. The lock cylinder is provided with screw notches 27 having shoulders 28 and 29, of which one can engage on one side of the transverse pallet 31, and the other on its other side, with the pin 31 located on the sliding rod 32 passing through the tubular part 12, and meshes with the rotary knob 33.

A locking bar 34 is attached to the bar 32, extending from the outside of the part 13 so that its ends can enter the slots 36 and 37 located behind the supporting plate 33. The aego or locking plate 38 is attached to the outside of the door and, as usual covered by a rosette 39.

As seen in FIG. 1, a coil spring 41 is inserted between the locking plate 38 and the shoulder of the outer handle. One end of the spring 41 is attached to the plate 38 and the other to the rod 16; This spring 41 serves to bring the door handles to their original position and to prevent play in the base plates, for which the spring is twisted along the axis. In the button 33, springs 42 are placed, the free ends of which can enter the grooves 43 located inside the rod 8.

The action of the proposed shutter is as follows. FIG. 1, the device is in the simple locking position, i.e. The inner door handle 9 can be rotated, while the outer handle 17 cannot be rotated if the key is not used. When using the handles, there is some kind of known door lock, not shown in the drawing. If you turn the knob 9 in any direction, then one of the beveled sides, 21 or 22 cuts will come in contact with the locking bar 34, so that the latter will move to the left. As a consequence, the ends of the spring 42 slid into the groove 43. and thus facilitated the shift of the striker 34 s position D, indicated in FIG. 3. The bar 34 is then locked, after that the y {e no longer captures the closing slits 36 and 37 of the plate 38, and the door lock can be unlocked by further turning the handle.

If the door needs to be opened from the outside, the key is inserted into the lock 26 and when the lock cylinder rotates by the screw slot 27, the cross pin 31 moves to the left, as a result of which the locking bar 34 is removed from the closure position in the manner already described.

The inner and outer door handles can be held in an open position, in which the pin 31 rests on the shoulder 29, which keeps the locking bar from sliding into the locking slot until the key is used to turn the lock cylinder 26 to a simple shutter position. While the lock cylinder 26 is in the simple shutter position, the locking bar 34 is in the locking position and is pulled out of the one by turning the knob 9. If the button 33 is then pressed, the locking bar 34 again returns to its simple locking position.

To bring the parts to the double-locking position, the locking bar 34 is put into a simple locking position by pressing the button 33, and inserting the key into the lock, turn it clockwise, as a result of which the pin 31 engages with the slot 27, where the shoulder 28 becomes on the left side of the pin 31. As a result, the locking bar 34 moves from the position C shown in FIG. 3, and placed in slots 23, 24, 36, and 37 (Fig. 2). In this position, both external and internal handles can not act, and only after inserting the key and installing the lock cylinder in a simple locking position, you can open the door lock in the same way.

When the cylinder is in the normal position in the outer door handle, you can open the shutter on the inside of the door by turning the knob, or push the door lock button 33 again to the locking position.

The subject of the patent.

1. A door bolt with a lock placed in the outer door handle, characterized by the use of a pole 32 (Fig. 1-3), fitted with a locking bar 34 and carrying at one end, under the influence of a spring 42 and located in the inner handle 9, a button 33, and on the other, a transverse pin 31 placed in the screw slot 27 of the cylinder inserted into the outer handle 17 of the lock 26; which shtanga, in order to move the strap 34 out of the locking position, moves inside the tubular part 12-16 by turning the knob 9 or turning the lock key, with the strap 34 coming out of the slots 18, 19, 23 of the tubular part 12-13

handles 9 and slides along the beveled sides of 21 or 22 cuts.

2. The use of the device for double door shut-off described in paragraph 1 of the door, characterized in that the walls of the slot 27 (Fig. 2) are equipped with shoulders 28 and 29, from which are provided for the installation of the rod 32 and the locking

the strips 34 in the opening position, while the other shoulder 28 serves to secure the said rod in the closing position in which the handle 9 is fixed so that the door shutter cannot be opened, for which the said shoulder 28 is moved by turning the key along the other side of the pin 31.
