Description

The proposed latch-lock for doors is of the type of valves that are locked with the help of a locking mechanism with a cylindrical cartridge, in which straight-line dials are placed, and a rotary plate with a pin entering the valve body and transmitting it.

In FIG. 1 shows the external view of the proposed door latch of the lock; FIG. 1a is a cross-section along the line CD in FIG. 1, fig. 2 is a longitudinal section of the locking mechanism; FIG. 2a is a cross-section along the line AB in FIG. 2, FIG. 2b is the same, side view, fig. 3 is a perspective view of the locking mechanism, FIG. 4 and 5 show details of the a-mechanism, FIG. 6 is a longitudinal section of the modified locking mechanism, FIG. 6a, the same section along the line EF in FIG. 6, FIG. 6b - the same, side view, fig. 7 and 8 are parts for the locking device / shown in FIG. 6, FIG. 9 is an external view of a modified latch-lock; FIG. 9a is a vertical incision along the line AB in FIG. 9, FIG. 9b is the same.

..

top view, FIG. 10 is the same longitudinal section of the locking mechanism with details; FIG. 11 and 12 — details of the mechanism shown in FIG. 9, and FIG. 13 is the key.

A metal bar 7 with brackets 2 is attached to the inner side of the door. The gate valve 3 is fitted with a slot / 5 closed with a fuse 17. A stop 72 is attached to the bar 7 above the gate 3, to which the fuse 77 abuts against the lowered position, lifted by lever 9, fastened to a cylindrical locking mechanism and rotating in one direction or the other when the key 4 is turned. Lever 9 with a pin on the end. entering the slot 75 of the valve 3. moves the latter (Fig. 1). The locking mechanism consists of a cylindrical cartridge 5 with longitudinal through holes 7S for four zugaltav 6 with notches and springs 7. The cartridge 5 is provided in the middle part with a recess for placing the split bar 8 (Fig. 3 and 4), for which the lock key LOW1 is attached to the bar 1 under the valve 3, against the stop 12. In addition, in the cartridge 5 there are four longitudinal notches that guide the finishing 6, fitted for this purpose with projections 20, which prevent the loss of the coal, pressed spring: 7, abutting iB vi "t 2,3 (Fig. 2, 2a, 21) and 3). The end of the cartridge 5 is covered by a cap W with a cross-shaped opening for the passage of the key 4, the barbs of which are arranged crosswise at different heights.

Instead of cuts 75, in the cartridge 5, outer grooves 24 (FIGS. 6-8) can be milled for zugalt, which are closed by tube 25, which is held on one side by a split bar 8, and on the other side by a lever 9 screwed on cartridge 5.

When closing the latch-lock, the key presses the zugalts 6 and advances them deeply until the cut-outs of the zuglts coincide with the cartridge's 11 leash 5. due to what the latter gets, it can rotate. Rotating, the cartridge turns and the lever 9, which raises the fuse 77, and the pin at the end of the lever 9 falls into the notch 75 of the valve and advances it to the right.

The cartridge can be installed not at the edge of the strip 7 of the valve, but in the middle below, between the brackets 2 (Fig. 9, 13). Accordingly, both the fuse 77 and the fixed stop 72 of the fuse are installed. When the chuck 5 (fig. 10) is rotated with the key 4 (fig. 13) from right to left, the lever 9 lifts the fuse / 7 and this releases the fuse 72 from the fixed stop 72 and moves the bolt 3 to the left; in the same way, es.pi rotate the cartridge 5 from left to right, the lever 9 will shift the bolt 3 to the right. In this way, the lock is locked both to the right and to the left, and

77, resting in a quiet state at the stop 72, will not allow the bolt 3 to be pushed off when burglary is used. By some outside tool, for example, a hundred, etc., etc.

The specified modification of the slide-lock allows it to be placed both on the right side of the door and on the left side.

PREV. 4 E P A T C and T A.

1, The door latch-lock, which locks the cylindrical locking mechanism with the application of a straight line directed into the spring of the spring zugalts, is installed (drilled into the turning position with the help of a wrench with a stepwise arrangement of the beards, characterized by the use of 77 (Fig. 1). Covering the slit 75 B body of the valve and resting in the lowered position attached above the valve) to the bar 7 stop 72. Located) 1Y behind the bracket 2 on the outermost end of the bar, and split bar 8 (Fig. 1, 3. 4 and 5), which is attached to the same strap 7 under the valve, pro) and in the designated abutment 72, and has a cylindrical bore to extend the shaft of the cylindrical cartridge to 5 liters of semi-slots for prisoners in new spring zugalts 6 (Fig. 2 and 8). an obstacle to the rotation of the mechanism before the cuts in these zugalts are installed in the same plane with it when polishing the key 4 (Fig. 5) with cross-shaped barbs 77.

2. Modification of the lock-lock described in paragraph 1, different tel. that the stop 72 and the bar 8 (Fig. 9) holding the cylindrical mechanism are attached to the bar 7 of the valve in the middle between the brackets 2 holding the valve.
