Description

LOCK

The invention relates to hardware, in particular to clamps, used to lock residential and public buildings.

A well-known lock containing a housing, a locking plate, a cylinder mechanism, a key, springs, a deadbolt with a locking tab, a cam with a ledge (Smo Lock 3 DB I disk waybill with a deadbolt. Passport. AO bolgogradneftemash) ..

There is a deadbolt in this castle. held by the lug protrusion on the bolt engaged with the ledge on the cam. In order for them to engage and lock the bolt, it is necessary to work with two hands: with one hand, rotate the cam through the key, and push with the other hand for the end of the bolt. This is very inconvenient, since one hand of a person (hostess) when unlocking the sewer is often occupied by a bag, for example, with product al1i.

A lock is also known, comprising a housing, a locking strip, a locking mechanism, a key, a cam, a deadbolt with locking tabs, a latch for holding the deadbolt in the unlocked position, and a locking switch protruding from the housing and mounted to interact with the locking strip (see. certificate. USSR # 1273480, E 05 35/04, ZOo.bb g.).

TaKiSs locks are produced by the Ryazan plant of calculating and analytical machines and the Vladimir Tractor Plant. In them, the latch (switch, fuse) of the latch protrudes from the housing, when closing the door, pushing from the latch, it releases the bolt lock, the lock closes automatically without the key, closes. Therefore, an absent-minded, forgetful, busy with thoughts, drunk, drunk, old or young person after closing the door can remain in the hallway or on the landing of the keyless entry door, which excludes him from returning to his premises and worsens the consumer properties of the castle. The mere presence of a bar protruding from the case makes the buyer of the castle think about the possibility of self-closing the lock and the buyer will not buy it.

The aim of the invention is to increase the consumer properties of the castle, so that the buyer wants to buy it.

housing (not protruding from the housing) with the possibility of interaction with the cam on a part of the angle of rotation, and the connection of the cam with the latch through the switch is made with one-way communication (This connection provides the impact of the cam on the latch and disengages the latch when turning the cam in only one direction .for example, towards unlocking the lock.

The design of the castle may have several options. A disconnect spruce can be mounted slid on a deadbolt and executed in the form of a slider (cracker).

Switch off the spruce can be made in the form of a lever mounted in the housing.

With such a lock, it cannot be slammed shut, it does not automatically lock when the door is closed, but is locked only with a key, which increases its consumer properties for scattered people. When unlocking the lock, one hand is enough, you do not need to press the bolt with the other hand

In Fig. A, a general view of the enamels is shown. In Figs. 2-d 6 showed a first embodiment of the lock: in Fig. 2, a section A-A, in Fig. I, in Fig. 3, a section B-B in Fig. 1; 4 - section bb in figure 2, figure 5 is a section in figure 2, figure 6 is a section bB in figure 1 (Lock in the locked position). In Figs. 7 4 10, a second embodiment of the taper is shown: in phiGo - section B-B in Fig. A, in Fig. 8 - section A-A in Fig. A, in Fig. 9 - section DD on, in Fig. S - section EE in Fig.8. On fiE.P depicts a third embodiment of the castle in the context of BB in fzhg.1s

The lock contains a housing I, a cylinder mechanism 2 (secrecy) with a hole (squared) for the key 3, fixed on the door 4 fixedly and the locking strip 5 (in this lock it may be absent), rigidly connected to the door jamb. In the case I are installed: with the possibility of translational movement of the bolt from the right to the right bolt (bolt) 7 with locking elements (bevel 8 at the end of the base of the bolt and Vn; blunt 9); articulated cam (leash) 10 connected to the handle II (Fig. I) rigidly, but with a cylinder mechanism 2 through the protrusions 12 in the hole of the cam; with the possibility of initial movement (pivotally) - latch 13 (latch, dog, stopper) to hold the bolt in the unlocked position of the lock. The bolt 7 is connected to the housing I through the tension spring 14, the cam 10 through the torsion spring 15, the latch 13 through the compression spring 16 ;.

a latch mounted inside the housing I (not protruding from the housing toward the locking strip 5, as is done in the prototype) with the possibility of interaction with the cam on a part of the angle of rotation, and the connection of the cam 10 with the latch 13 through the switch 17 is made with one-way communication. This connection ensures that the cam acts on the latch and disengages the latch only when the cam is turned in one direction, for example, in the direction of unlocking the jaw. In this embodiment of the lock, the switch 17 is made in the form of a trough-shaped slider (cracker) (FIG. 5) mounted movably on one of the two bars 18 of the bolt 7. The switch (slider) 17 is provided with a protrusion (tooth) 19 for interacting with the cam 10 and is preloaded leaf spring 20 to the base of the bolt 7.

The castle works as follows. 2, the lock is shown in the unlocked position. The bolt is kept from moving to the left by two latches: a latch 13, leaning against the bevel 8 of the bolt 7 and a ledge of the sulash 10, engaged with the protrusion 9 of the bolt 7. To lock the lock, rotate the cam 10 (not, for the part of the possible angle of rotation of the cam, the whole angle of rotation of it , not to the extreme position) with the handle II or with the key 3 in the direction of unlocking the lock (in FIG. 3 - counterclockwise). The cam 10 disengages from the protrusion of the deadbolt 9 (this latch is superfluous, may be absent), one latch ceases to hold the deadbolt from moving to the left: the cam 10 pushes the switch 17 with its surface 21 through the lug 19 and the latch 13 from the deadbolt The latch 13 moves away from the bevel 8 of the deadbolt 7 and disconnects. The bolt 7 under the action of the spring force, rotation 14 moves to the left, enters the locking bar (or its analogue on the jamb) 5 and locks the door. The phiGoZ shows the solid lines of the beginning of the locking of the lock, in FIG. 6 - end of the mashing phase of the castle.

To unlock the locked lock (Fig. 6), turn the cam 10 with the key 3 from the outside or with the handle II from the inside of the room towards the unlocking side (in Fig. 6 counterclockwise). The cam 10 with its surface 21 engages with the bolt protrusion 22 and moves it to the right extreme position (FIG. 3) o Under the action of the compression spring 16, the latch 13 will rotate and rest against the bevel 8 of the bolt. The latch 13 and the switch 17 will occupy the position shown in Fig "2. The bolt is fixed, held in the unlocked position by the latch 13. The cam is in the position shown in FIG. 3 by a dashed line; Release the handle Drank the key 3 or turn the key 3 (handle II) to the cylinder mechanism of FIG. 3 clockwise. Cam 10, under the action of torsion spring 15, will itself rotate in the direction of the position shown in FIG.

with such movement with its surface 23 (FIG. 3), it pushes the spruce 17 off to the left of the base of the bolt 7 (from the bevel 8), disengages with it and takes a better position in figure 2. With this direction of rotation of the cam 10, it does not act on the latch 13, does not turn it off, since the switch 17 is mounted on the bar 18 of the bolt 7 with the ability to move both across the axis of the bar and along its axis.

After locking or unlocking the lock, remove the key 3 from the squat of the cylinder mechanism. Locking is not automatic (as in analogues), but only with a key, which is very convenient for people who can be forgetful. These are not only children and elderly people, but sometimes very attentive young people, if, for example, they are drunk, drunk, or busy with everyday and other problems. When unlocking the lock, it is enough for a person to turn the cam 3 with the key 3 towards unlocking. Zayov 7 by itself will be installed in the right position and fixed securely. It is not required (as in the prototype and analogues) to turn the cylinder mechanism 2 with a key with one hand and push the bolt 18 over the end of the bolt 7 with the other hand. This convenience will be appreciated not only by one-armed, but also by very modest normal, healthy buyers of the lock, whose return home, one hand is always busy either with a grocery bag or with something else.

Thus, the proposed castle is very convenient and needs a large part of the population and it is according to buy it even at a higher price than analogues:

In the second version of the lock, the latch is made in the form of a lever (strap, plate) 25 mounted pivotally inside the housing and provided with a protrusion (tooth) 26 for interacting with the groove of the depression, ledge) 27 on the bolt 7. The latch switch is made in the form of a strap 28, freely installed in the groove of the bar bolt 18 and the compressed compression spring 29, the switch (strap) 28 is provided with a protrusion (tooth) 30 for interaction with the cam 10.

This version of the lock works in the same way as described above.

In the third embodiment of the lock (Fig. II), the latch 33 is provided with a protrusion 34 and is mounted in the housing I pivotally, with the possibility of rotation relative to the axis of the cam 35, the bolt 36 is equipped with a protrusion 37 for interaction (engagement) with the protrusion (tooth) 34 of the latch. The latch 33 is connected to the housing through a compression spring 38 and a strap 39 connected to the latch through a protrusion on it and a ledge (groove) on the latch. The switch 40 is made in the form of a lever (plate), is mounted in a hinged body, connected to the housing through a spring 41 and comprises a protrusion 42 for interacting with the protrusion (teeth; ohm)

 cam 35 and with a one-sided protrusion 44 of the latch 33,

This castle works as follows. In Fig. And the lock is shown in the unlocked position. The protrusion protrusion 34 is coupled to the bolt protrusion 37, which is held by two latches: the retainer 33 and the cam 35 (this fshator may be absent) engaged with the bolt protrusion 45,

To lock the lock, close the door and turn on the cam 35 in the unlocking direction (in phiGoI - counterclockwise) with the key 3 or handle (permanent key) II. The cam will disengage with the protrusion 45 of the bolt 36 (one latch does not hold the bolt), its protrusion 43 will turn the switch 40 and the latch 33. The protrusion 34 of the latch 33 will disengage with the protrusion 37 of the bolt 36. The bolt moves to the left by the action of the torsion force 46, and enters the locking strip 5 and locks the lock. The plug is locked with key 3, not automatically, without slamming. The key is removed from the cylinder mechanism 2 and calmly leave.

If, by mistake, the key is turned not at, but at a larger angle, then the protrusion 43 of the cam 35 itself disengages from the protrusion 42 of the switch (this is achieved by choosing their sizes during construction). This eliminates the excessive rotation of the latch 34.

To unlock the lock, insert the key 3 from the outside into the keyhole and turn the cam 35 towards the unlocking direction (counterclockwise). Cam 35, with its surface 47, releases the deadbolt 36 by its protrusion 48 to the right; At an angle of rotation of 30 ° - | 40 by the projection 43, the cam will turn off the spruce tree 40 and the latch 33. Upon further rotation, the protrusion 4S of the cam will disengage from the protrusion 42 of the switch (it will be on the physical plane not lower, but higher than the protrusion 42 of the switch). The interaction between the cam 35 and the latch 34 ceases. At the moment when the bolt 36 is in the right extreme position, the protrusion 34 of the latch 33 is secured with the protrusion 37 behind, the owl is under the action of the compression spring 38. The bolt is locked in the unlocked position. The key is turned in the opposite direction and removed, from the well, the cam 35 under the action of a torsion spring (not shown in FIG.) Will itself turn into the position shown in FIG. II and engage with the bolt protrusion 45. Upon rotation, the cam with its protrusion 43 first engages with the protrusion 42 of the switch 40 and rotates it (counterclockwise), and then disengages. However, such a movement of the cam 35 and the breaker 40 to the latch 33 is not transmitted, since the bevel 44 on the latch is made unilateral not like a groove; This ensures that the cam is connected to the latch via a one-way disconnect switch.

(when turning the cam, for example, only in the direction of scrubbing). The switch 40 with its protrusion 42 is pressed against the bevel 44 of the lock, however, the force of the torsion spring 41 is not enough, overcoming the force of the compression spring 38 to rotate the lock 33.

In all three versions of the lock, the interaction of the cam with the switch occurs only on a part of the angle of rotation of the cam at, This angle can be large, but it must be significantly smaller than the total angle of rotation () of the cam, so that even a distracted person can lock the door. If the angle of their interaction is equal to or close to the full angle of rotation of the cam, then the lock may not be locked.

The connection of the cam with the latch through a one-way switch, with the cam rotating (only), it is only necessary in one direction to lock the deadbolt in the unlocked position.
