Abstract

An automatic locking padlock allows improved operating conditions, eliminating the spontaneous locking of the lock. The padlock consists of a lock case and a striker plate. In the case of the lock, a secrecy mechanism with a rotating cylinder is installed, on the end of which there is a groove with a bar placed in it, a spring-loaded bolt with two locking lugs, a latch with a lug, a cam and a fixed key. The cam of the lock is made with a ledge, which, interacting with one of the locking protrusions of the bolt, ensures its fixation in the open state. To ensure that the lock operates in the automatic locking mode, the distance from the cam axis to its ledge and the distance from the locking protrusion to the second fixing outrode Ш of the deadbolt are chosen correspondingly large and equal to the working stroke of the cage. 4 il. with

00 The invention relates to locks for wooden doors used in the mass construction of residential and public buildings. The purpose of the invention is to improve the performance properties of the castle. Figure 1 shows the lock mechanism, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2 .; figure 4 - section bb In figure 2. The automatic locking padlock contains a locking bar I, a secrecy mechanism 2 with a rotating force transmission cylinder 3, at the end of which there is a rectangular groove 4 with a plate 5 fixed in it, and a case 6. A spring-loaded spring 7 of a twist bolt is placed in the case 6 8, which has locking protrusions 9, 10 and a guide groove II, a retainer, 12 with a protrusion 13 and a groove 14, which includes a protrusion 15, of the plank 16, spring loaded (17 pressing the cam 18 with a ledge 19 on it, two cylindrical guides 2 0.21 spikes 22; a permanent key 23, made in the form of a handle to the lock, comes with a set of keys 24. The device works as follows: When the lock is opened with the key 24, the torque through the rotating cylinder 3 transfers the power of the mechanism 2 of secrecy It is transmitted to the bar 5, which, interacting with the protrusions 22 of the cam 18, rotates it. The cam 18 is mounted by the guide cylindrical part 2 into the body 6 and has a common axis of rotation with the cylinder 3 of the power transmission by the bar 5, the fixed key 23 and the latch 12. Moreover fi 12 with respect to cam ka 18 can rotate independently. The cam 18 rotates, rests on the locking protrusion 9 of the bolt B and transmits the force to it. Since the bolt 8 by the guide groove 11 covers the cylindrical part 21 of the cam 18, it overcomes the force of the spring 7 of the torsion and leaves the striker 1 and enters the housing 6. The cam 18 rotates until the locking protrusion 9 enters the ledge 19 of the cam 18, thereby the cam 18 fixes the bolt 8, preventing it from jumping out of the housing 6. From this moment on, the lock is open. The bar 16, with the doors closed, rests on the locking bar 1 and, with its protrusion 15, which enters the groove 14 of the retainer 12, holds it in the rotated position, preventing the protrusion 10 of the bolt 8 from being fixed. The bolt 8 when its locking protrusion 9 enters the ledge 19 cam 18, does not jump out when the doors are opened and closed repeatedly (thus ensuring a short exit from the room without slamming the doors, for example, after correspondence, etc., since the cam 18 remains stationary). When leaving the room for a long period of time, opening the doors (the bar 16, not having a stop under the action of the spring 17, pops up and locks 12 with the help of the projection 15, the projection 13 of the clamp 12 is now ready to catch the locking protrusion 10 8), it is enough to turn the permanent key 23 of the non-MeHtie by 15 ° (until it clicks, then the permanent key itself takes the desired position under the action of the spring) in the direction opposite to the lock opening. In this case, the cam 18 will release the bolt 8, which under the action of the spring of the torsion 7 will begin to move in the direction of closing, but it is caught by the protrusion 13 of the latch 12 by the protrusion 10, not allowing it to pop out. This provides the possibility of elevation from the room without opening the lock. After leaving the room and closing the doors, the bar 16, resting against the locking bar 1, enters the body 16 and by means of the projection 15 rotates the latch 12, which releases the locking hub 10 of the bolt 8 and the latter pops out of the body 6, locking the door. In order for the retainer 12 to catch the locking protrusion 10 of the bolt 8 (when the bolt 8 is released from the engagement with the cam 18) with the doors open, the distance from the protrusion 13 of the retainer 12 to the locking protrusion 10 on the bolt 8 must be less than the cam axis 18 to its shoulder 19, i.e. The cam 18 must retract the bolt 8 into the housing 6 by such an amount that the locking protrusion 10 of the bolt 8 would pass the protrusion 13 of the latch 12. When locking the position of the bolt 8 (when the latch 12 with its lug 13 catches the protrusion 10 of the bolt 8) it does not

must protrude from the housing 6 by more than 0.5 mm or sink in more than 1 mm (as required by the standard for locks). Such an optimal arrangement of the bolt 8, when it does not interfere with the closing of the doors, is called working, and the stroke of the bolt 8 to such a fixed position is called the working stroke of the bolt. The source data for calculating the movement mechanism of the bolt is the working stroke of the bolt, and it is equal to the departure of the bolt from the lock body. According to the standard, the bolt reach must be at least 22 mm (in the proposed construction, the minimum 15 bolt offset is 22 mm). Therefore, the protrusion 13 of the retainer 12 must fix the bolt 8 behind the protrusion 10 when it passes a working stroke of 22 mm, and the second fixed position of the bolt 8 on the protrusion 19 of the cam 18 must be greater than the working stroke. In the proposed design, the second fixed position occurs after the stroke of the bolt at 23 mm. Stroke difference per 1 mm 25

It is optimal for us, since an increase does not lead to an increase in the angle of rotation of the key, and a decrease to an increase in the accuracy of manufacturing parts of the lock, as well as adversely affecting the reliability of the lock.

In order to open the lock with key 24, it must be turned until the bolt 8 enters the housing 6 by means of the cam 18 and locks onto the ledge 19 of the cam 18. The angle of the key rotation depends on the stroke of the bolt and, as standard change in the direction of increasing, the angle of rotation of the key can also change in the direction of increasing (in the proposed construction, the angle of rotation of the key is minimal - 120 °) Therefore, in order to unlock the key when the lock is open, it must be turned in the back lock directed and. When the key is turned, the plank 5 of the mechanism 2 of secrecy is rotated, transmitting the force of the kula-50 to 18, since with the lock open

The cam 18 has a fixed position (i.e., it holds the bolt 8), so the key 24 cannot be fully returned to its original position. The bar 5 is able to freely rotate between the projections 22 of the cam 18 to 105, therefore the bar 5 is given an additional free travel in the opposite direction by 15 ° due to the notches 5. Since the angle of rotation of the key 24, as has been said, depends on the stroke of the bolt 8, Then the angle of the recesses 4 at the end of the cylinder 3 may vary. Moreover, in the proposed concrete version of the sacking and repair of doors and the installation of new locks.
