Description

Technical field
The invention relates to a locking mechanism. More specifically, it relates to a locking mechanism for a secure cylinder lock.
State of the art
Cylinder locks usually contain a locking mechanism. The locking mechanism in such locks usually contains a first actuator, a second actuator and a locking cam located between them. Actuators are actuated by a key or handle to allow selective cam rotation. The cam typically contains an axis and a tooth protruding from it.
The switching mechanism (clutch) as part of the locking mechanism is actuated to ensure its (her) selective connection with the first or second actuator. The need for the coupling is due to the fact that actuators driven by a key are locked against rotation until a key is inserted. Therefore, for example, if the lock mechanism contains two such actuators, inserting a key into the first actuator will automatically break the chain of force transmission between the second actuator and the cam, so that the cam can be rotated by the first actuator. Alternatively, inserting a key into the second actuator will move the clutch so as to form a force transmission chain between the second actuator and the cam.
A cylinder locking mechanism is installed in the lock housing containing a mechanism for locking the bolt. The cam is located in the space between the front and rear walls of the housing. When the cam is rotated, its tooth acts on the mechanism of the deadbolt to insert or remove the deadbolt and, accordingly, lock or unlock the lock.
Cylinder locks of this type may be subject to unauthorized unlocking attempts. Such attempts may consist in removing the closest (usually outer) actuator and manually turning the cam to actuate the deadbolt mechanism. Alternatively, the cam is removed and the deadbolt is retracted into the lock housing using an appropriate tool.
This problem is exacerbated when an actuator is installed on the inside of the lockable object, controlled by a pen, not a key. The cam associated with the handle of the actuator can rotate freely, since no key is required to rotate the handle.
Disclosure of invention
The invention is directed to an improved cylinder lock.
According to a first aspect of the invention, there is provided a cylinder lock comprising:
a first actuator mounted rotatably in its housing,
second actuator
a locking cam comprising an axis and a tooth protruding from it in a radial direction, the locking cam being mounted between the first and second actuators with the possibility of rotation around the axis of the lock, and
a switching mechanism configured to selectively form a force transmission chain between the first or second actuator and the locking cam and having a protected position in which it is directly connected to the cam and to the first actuator to secure the cam relative to the first actuator.
Limiting the movement of the cam axis relative to the first actuator is useful since complicates cam displacement after removal of the second actuator and blocks the rotation of the cam around its axis.
According to a second aspect of the invention, there is provided a cylinder locking mechanism comprising:
first actuator
second actuator
a locking cam comprising an axis and a tooth protruding from it, wherein the locking cam is rotatably mounted between the first and second actuators around the axis of the lock, and
a blocking element at least partially overlapping the cam tooth in a direction parallel to the axis of the lock.
The locking element will effectively impede access to the locking cam if the outer part of the locking mechanism is removed. As a result, it becomes more difficult to rotate the locking cam to unlock the lock. It will also be difficult to remove the cam from the mechanism.
On the locking element of the locking mechanism, it is desirable to perform a deliberately weakened area located on the side of this element that is opposite to the tooth of the cam. As a result, if you expose the lock to force, it will break in a given place, leaving the blocking element intact, i.e. preventing access to the tooth of the cam.
It is also desirable to use a connecting component connecting the first and second actuators and the bearing blocking element. The connecting component preferably comprises fastening means for attaching the locking mechanism to the lock body.
The weakened zone is preferably located on the connecting component. In this embodiment, this zone is included in the “critical” chain of force transfer, and manipulation of the actuator with a high probability will lead to breaking of the connecting component in the desired location.
The weakened zone is preferably a groove formed on the outer surface of the connecting component, and is located between the blocking element and the first mating means to allow the holding component to mate with the first or second actuator.
According to a third aspect of the invention, there is provided a lock comprising:
a locking mechanism comprising a first actuator, a second actuator, a locking cam comprising an axis and a tooth protruding from it, the locking cam mounted between the first and second actuators to rotate around the axis of the lock, and
a lock case having a first wall and a second wall.
The locking mechanism is installed in the lock case so that the cam tooth is between the first and second walls, and the cam axis protrudes axially from the first wall.
The implementation of the axis of the cam protruding from the housing does not allow you to move and rotate the axis of the cam and eliminates the possibility of access to the internal parts of the lock.
Installing the locking mechanism in the lock body such that the cam tooth is between the first and second walls and the cam axis extends axially from the first wall is preferred. It is also desirable that the blocking element also protrudes from the first wall. In this case, if the lock is broken, the protruding parts of the locking element and the cam axis will fill the entire cutout surface in the lock body, which will greatly complicate further manipulations with the lock. The cam axis and the locking element preferably extend approximately the same distance. For example, the end surfaces of the axis of the cam and the blocking element may lie in the same plane. The cam axis also protrudes from the second wall.
According to a fourth aspect of the invention, there is provided a cylinder locking mechanism comprising:
first actuator
second actuator
a locking cam comprising an axis and a tooth protruding from it, the locking cam being mounted between the first and second actuators to rotate about the axis of the lock.
The axis of the cam contains a holding component extending from it in the radial direction and restricting the movement of the axis of the cam in the axial direction relative to the supporting surface.
The presence of a holding component, such as a protrusion on the axis of the cam, effectively prevents axial displacement and rotation of the cam after it becomes available as a result of removal of one of the actuators. The retaining component typically interacts with the surface of the lock body on the inside of the lockable object. Alternatively, the protrusion may abut against the outside of the lock case outside the lockable object, not allowing access to the internal volume of the lock case with tools.
It should be noted that the third and fourth aspects of the invention correspond to alternative solutions to the problem arising in the event of a breakdown of the lock with access to the internal volume of the lock by removing the cam from its axis.
According to a fifth aspect of the invention, there is provided a handle assembly for a cylinder locking mechanism, comprising:
handle body
a cylinder mounted inside the housing, and
a handle connected to the housing and the cylinder in such a way that in the first state of the assembly the cylinder is fixed against rotation relative to the housing, and in the second state, the cylinder is able to rotate relative to the housing about the main axis when a torque is applied to the handle. Moreover, the handle is made with the possibility of axial movement to transfer the node from the first state to the second state.
In this case, before turning the handle, the user must press on it (or, alternatively, pull it off). Activating the handle by pushing effectively prevents unauthorized cam rotation from the outside of the lock after removing the external actuator. This makes the cylinder lock using the handle on its inside more secure.
The handle assembly made in accordance with the fifth aspect of the invention is installed in a cylinder locking mechanism, comprising:
a first actuator mounted rotatably in its housing,
a locking cam containing an axis and a tooth protruding from it in the radial direction, while the locking cam is mounted between the first actuator and the handle assembly with the possibility of rotation around the axis of the lock, and
a switching mechanism configured to selectively form a force transmission chain between the locking cam and (i) the first actuator or (ii) the lock cylinder.
The switching mechanism preferably has a protection state in which it is connected to the lock cylinder without being movable.
The switching mechanism (clutch) is preferably configured (configured) with the possibility of coming into a protected position in the event of removal of a component of the locking mechanism, usually the first actuator. In this case, in the event of a hacking attempt by removing the cylinder, the clutch will move to the protected position in which it is connected to the cylinder. Provided that the handle is in its first state, the clutch and therefore the cam will be locked against rotation, which will prevent the lock from being manipulated. In this case, the legitimate user will be able to transfer the handle to the second state in order to unlock the room from the inside, having passed through an alternative way.
According to a sixth aspect of the invention, there is provided a cylinder locking mechanism comprising a housing and a cylinder rotatably mounted in the housing and having a radially projecting surface cooperating with a locking member projecting radially inward from the housing.
This embodiment increases the security compared, for example, with a retaining ring holding the cylinder, since it requires less space than when locking by means of a retaining ring, and, therefore, allows to increase the length of the locking cam and thereby reduce the likelihood of its displacement from its axis inside the lock case . In addition, the groove for receiving the locking element on which the protruding surface is formed may be located inside the actuator housing. This distinguishes the invention from devices with a locking ring, in which the groove for the locking ring must be located outside the housing. Such grooves serve as sources of stress in the cylinder, so that the execution of the groove inside the housing reduces the likelihood of damage due to external forces. Thus, the cylinder lock according to the invention has increased security.
The locking element is preferably a pin passing through the wall of the housing of the locking mechanism.
It is also desirable to use an additional locking element protruding into the housing with the mutual displacement of these elements around the circumference of the housing. It is preferable to have three locking elements uniformly distributed around the circumference.

The implementation of the invention
As shown in FIG. 1, the locking mechanism 100 comprises a first actuator 102, a second actuator 104, a cam 106, and a clutch assembly consisting of first and second clutch subassemblies 108, 110. The mechanism 100 further comprises a holding component 112.
The first actuator 102 comprises a housing 114 and a first lock cylinder 116. The housing 114 consists of a hollow cylindrical part 118 and a radially protruding part 120 from it. The cylindrical part 118 is provided with two radial through holes 119. The protruding part 120 is provided with a blind hole 122 extending parallel to the cylindrical part 118. In the radial part 120 there is also a pair of transverse drilling 124 .
The first cylinder 116 comprises a locking pin mechanism for inserting a key. The first cylinder 116 is able to rotate inside the housing 114 of the first actuator with the introduction of the corresponding key. Until the key is inserted into the first cylinder 116, this cylinder is locked against rotation inside the housing 114 of the first actuator. The functioning of such locks is well known to specialists, so there is no need to consider it.
The first cylinder 116 has an annular groove 126, a key hole 130 extending in the axial direction, a first cutout 132 for mating with the sleeve and a second, opposite to it, cutout 134 for mating with the sleeve. Both of these cuts extend axially from the end face of the first cylinder 116. The first cylinder 116 also has a radially oriented hole 131 for the locking pin.
The second actuator 104 comprises a housing 136 and a second cylinder 138. The housing 136 of the second actuator is substantially similar to the housing of the first actuator, i.e. it also contains a cylindrical part 140 and a protruding radially part 142. This part is provided with a blind hole 144 and a pair of transverse drilling 146.
The second cylinder 138 is also able to rotate inside the housing 136 of the second actuator when the key is inserted into the key hole 148. In this case, the second cylinder 138 is provided with an annular groove 150 for the retaining ring. When the second cylinder 138 is located inside the housing 136 of the second actuator, this groove protrudes from a portion 140 of the housing 136.
The first clutch subassembly 108 comprises a compression spring 152 and a first clutch component 154 that has a stepped axis 156 with a drive member 158 projecting in a radial direction from its larger diameter portion. The first component 154 also comprises a cylindrical reinforced steel liner 160 mounted in the axial bore of the component, which is provided with a locking pin 162 radially movable and spring-loaded radially outward by means of a compression spring 164.
The second coupling subassembly 110 comprises a second coupling component 166 having a stepped axis and a drive member 168 extending radially from it. The second subassembly 110 of the clutch further comprises a push pin 170 mounted abutting to the larger diameter portion of the second clutch component 166.
The locking cam 106 comprises a substantially cylindrical axis 172, from which a cam tooth 174 extends in a radial direction. Tooth 174 is made expanding as it moves farther from axis 172 of the cam.
This axis is essentially hollow, but has a central wall 176 with an axial hole 178 passing through it in the axial direction. The profile of this wall makes it possible to interact with it, on the one hand, of the drive element 158 of the first coupling component 154 or, on the opposite side, a drive member 168 of a second coupling component 166.
Through the outer wall of the axis of the cam 172 passes a radial hole 173 under the locking pin.
The first axis 182 and the second axis 184 depart from the body 180 of the retaining component 112 in opposite directions, in each of which two holes 186, 188 for the pins, respectively, are made. The body 180 is essentially cylindrical and has flat sections 190 on its upper and lower surfaces. In addition, a blocking member 192 having a concave surface 194 in the form of a portion of a cylindrical surface departs from the body 180. A transverse through-hole 181 is provided in the body 180 for attaching the body 180 to the lock body. The holding component 112 is made as a single part.
An annular groove 113 is formed on the second axis 184, between its free end and the blocking element 192. This groove is located between the blocking element 192 and the first point at which (as will be described later) the holding component is attached to the lock body, i.e. the first hole 188. The groove 113 forms a deliberately weakened zone, the presence of which ensures that in case of power removal of the second actuator 104, the retaining component will break at the groove 113 and as a result will remain in its place. It should be noted that the groove is not in direct contact with the blocking element 192, so that the breaking of the axis does not affect this component and does not lead to the appearance of any cracks in it.
The assembly of the locking mechanism 100 is performed in the following order.
The cylinders are embedded in their respective housing 114, 136 actuators. The first cylinder 116 is axially fixed inside the housing 114 of the first actuator by holding the locking pins through the holes 119 with them entering into the annular groove 126 on the cylinder 116. The second cylinder 138 is fixed inside the housing 136 of the second actuator by means of a locking ring inserted into the annular groove 150 .
The compression spring 152 is set to press the first cylinder 116 and bring the first coupling component 154 into conjunction with the first cylinder 116 so that the drive element 158 fits into the second cylinder cutout 134. At the same time, a hardened steel liner 160 is placed inside the stepped axis 156. The locking pin 162 is inserted inside the stepped axis 156, overcoming the force of the compression spring 164.
Then, cam 106 is placed over the first coupling component 154 and a smaller axis portion of the second coupling component 166 is drawn through the through hole 178 in the central cam wall 176 until it stops in the first coupling unit 108. Moreover, due to the elasticity of the compression spring 152, the coupling component 166 can be displaced in the axial direction.
The pressure pin 170 is mounted abutting in the second coupling component 166, and the second cylinder 138 is abutted on the pressure pin 170. The housing 114 of the first actuator is connected to the housing 136 of the second actuator by means of a holding component 112. For this, the first axis 182 and the second axis 184 injected into the blind holes 122, 144 of the housings 114, 136 of the first and second actuators, respectively. In order to fasten the entire locking mechanism, locking pins 196 are inserted through the transverse holes 124, 146 into the holes 186, 188 of the retaining component.
It should be understood that in the working lock the clutch assembly is movable, so that the first clutch component 154 and the second clutch component 166 can be axially displaced and mate with the cam 106. Compression spring 152 presses these components in the direction of the second actuator 104. As a result, the drive element 158 is mated with the central wall 176 of the cam 106. Therefore, when the key is inserted into the first cylinder 116, its rotation causes the first coupling component to rotate as a result of the interaction between the drive element volume 158 and second cutout 134 under the coupling. This, in turn, causes the cam 106 to rotate as a result of the interaction of the drive element 158 with a corresponding recess made in the central wall 176 (not shown). On the other hand, if the key is inserted into the second cylinder 138, the force from it is transmitted through the push pin 170 to the second coupling component 166, which pushes the first coupling component 154 out of contact with the cam 106 and introduces the drive element 168 into the undercut in the central wall 176 of the cam 106.
Thus, if the key is inserted from within the lockable space (in which the first actuator is located), by turning this key you can turn the cam 106 and, as a result, lock the lock or remove any deadbolt by turning the tooth 174 of the cam. Alternatively, if the user is outside, he can enter the key into the keyhole 148 of the second cylinder 138, and this activates the clutch components 154, 166, so that the drive member 168 engages with the cam 106, allowing the door to be unlocked from the outside.
It should be understood that if the second cylinder 138 is removed with or without the second actuator housing 136, the pressure pin 170 and the second coupling component 166 will drop out. This will allow the compression spring 152 to push the first coupling component 154 further than its extreme position, so that the locking pin 162 extends under the action of the spring 164 and enters its hole 131 on the first cylinder 116, blocking the coupling. In addition, the locking pin 162 will pass through the hole 131 and will enter the radial hole 173 in the axis of the cam 172. As a result, the cam 106 will be fixed relative to the first cylinder 116, which will make it difficult to move or remove the cam. Since the cam will be connected to the first cylinder 116, a person trying to act on the lock mechanism from the outside will not be able to rotate the cam 106, since it is fixed relative to the first actuator 102, which cannot be rotated without entering the key from the inside.
As illustrated in FIG. 2, additional protection is provided by the presence of a blocking member 192 that extends to the cam axis 172. It has already been noted that the blocking member 192 has a concave cylindrical surface 194 that abuts against the cylindrical surface of the cam axis 172. Moreover, additional protection is provided due to the fact that in the event of removal of the second cylinder 138 and the housing 136 of the second actuator, a person trying to break the lock will not be able to access the cam tooth 174 to rotate it, since this access is blocked by the blocking element 192. note that the range of rotation of the tooth 174 of the cam from its nominal position is only 10-15 ° when the lock is activated, so that the blocking element 192 will block at least part of the cam 106 in all positions niyah within the angle of normal cam movement. Therefore, it is extremely difficult to access the cam tooth 174 to rotate or remove the cam 106.
3, a locking mechanism 100 is shown placed in a lock housing 10 having a cutout 12 for a cylinder locking mechanism. Cam 106 may rotate within lock housing 10. It can be seen that if the second actuator 104 is removed (so that the second axis 184 at the groove 113 must be broken), the cam axis 172 protrudes from the lock body 10. At the same time, the body of the retaining component 180 and the locking element 192 also protrude from the lock body 10 to prevent access to the cam tooth 174 located inside the housing 10. There is no gap into which the tool can be inserted to gain such access. The exact correspondence of the lock case to the Europrofile will further complicate such a manipulation with a cylinder lock.
When the locking mechanism 100 is in a locked state, the cam tooth 174 is offset relative to the notch 12. Therefore, the cam 106 cannot be axially removed without turning it to the unlocking position. This rotation is not possible because, as mentioned, the cam is now attached to the first actuator 102, which cannot be accessed until a key is inserted into the lock from the inside.
Figure 4 shows the second locking mechanism 200. This mechanism is similar to the first locking mechanism 100, and the digital designations of similar components of this embodiment are increased by 100.
Cam 206 is identical to cam 106 except that it has radial protrusions 302, 303 at its end corresponding to the first actuator.
5, the locking mechanism 200 is shown placed in the lock case 10 having a corresponding cutout 12. The lock case 10 has external and internal sides 14, 16. It can be seen that the first actuator 202 is installed on the inner side 16, and the second actuator 204 from the outside 14. The protrusions 302, 303 of the cam 206 abut against the outer surface of the lock body 10 on its outer side 16. In this case, if the second actuator 204 is removed, the cam 206 cannot be easily rotated or removed since the protrusions 302 , 303 pyran in the lock housing 10.
The protrusions 302, 303 are diametrically opposed, and the protrusion 303 is aligned axially with the cam tooth 274. This embodiment facilitates the installation of the locking mechanism 200 in the housing 10 of the castle. The protrusion 303 will abut against the lock body 10 only if the mechanism 200 is in a locked state.
FIGS. 6A, 6B show a locking mechanism 400 that includes a first actuator 402, a second actuator 404, a cam 406, and a clutch assembly consisting of first and second subassemblies 408, 410. The mechanism 400 further comprises a holding component 412.
The first actuator 402 comprises a housing 414 and a first lock cylinder 416. The housing 414 consists of a hollow cylindrical portion 418 and a radially extending portion 420 protruding therefrom. The cylindrical portion 418 is provided with two radial through holes 419. The protruding portion 420 is provided with a blind hole 422 extending parallel to the cylindrical portion 418 and a pair of lateral drills 424.
The first cylinder 416 has an annular groove 426 and a key hole 430 extending in the axial direction. The first cylinder 416 also has a hole 431 for the locking pin, oriented in the axial direction.
The first cylinder 416 comprises a locking pin mechanism for key insertion. However, the key to the first cylinder 416 is not manufactured. Instead, a handle assembly 500 is supplied.
The handle assembly 500 includes a handle 502 with a head 504 attached to the first axis 506, to which, with the formation of a shoulder 509, a second axis 508 is attached, provided with a cutout 510 and a pin 512 oriented perpendicular thereto. The assembly 500 further comprises a key element 514 capable of cooperating with the cylinder 416 to rotate it relative to the housing 414. To rotate the cylinder 416, the key element 514 must be fully inserted into it. If the element 514 is not completely inserted into the cylinder 416, the cylinder 416 will be blocked from rotation relative to the housing 414.
The key element has a backward facing shoulder 515.
The second actuator 404 comprises a housing 436 and a second cylinder 438. The mechanism 404 is substantially similar to the second actuator 104 of the lock mechanism 100 and therefore is not described in more detail. The first coupling subassembly 408 comprises a compression spring 452 and a first coupling component 454 with a drive member 458 extending radially from this component. The first coupling component 454 also includes a locking pin 462 radially movable and spring-loaded radially outward by means of a compression spring 464.
The second coupling subassembly 410 comprises a second coupling component 466 having a stepped axis and a drive member 468 extending radially from it.
The cam 406 comprises a substantially cylindrical axis 472, from which a tooth 474 extends in a radial direction. The tooth 474 is made expanding as it moves farther from the cam axis 472.
The axis 472 of the cam is essentially hollow, but has a central wall (not visible in FIG. 6A) with an opening passing through it in the axial direction. The profile of this wall allows it to interact with it on one side of the drive element 458 of the first coupling component 454 or on the opposite side of the drive element 468 of the second coupling component 466.
A radial hole 473 passes under the locking pin through the outer wall of the cam axis 472.
From the body 480 of the retaining component 412, the first axis 482 and the second axis 484 extend in opposite directions, each of which has two pin holes. The blocking element 492, protruding in the radial direction relative to the body 480, can be slidably moved along the second axis 484 and locked with a pin 481. The blocking element 492 has a concave surface 494 in the form of a portion of a cylindrical surface. The body 480 has a transverse through-hole for mounting the body 480 to the lock body.
With respect to the assembly and operation, the locking mechanism 400 is similar, with some exceptions, to the locking mechanism 100. Thus, the assembly of the handle assembly 500 provides for the installation of a compression spring 516 on the axis 508 until it stops against the shoulder 509. The key element 514 is guided through the spring 516 into the notch 510. The shoulder 509 serves as a stop for the spring 516. Then, the handle assembly 500 is inserted into the cylinder 416 and secured with a pin 518, which fixes the key element 514 relative to the axis 508. The pin 518 can slide with sliding in the hole 431. The spring 516 abuts against the three cylinder 416 (not visible in Figure 6A), so that the handle 502 is pushed from the cylinder 416.
Finally, the cylinder 416 is fixed in the housing 414 using a pair of pins 520 by passing them through the holes 419 and entering them into the groove 426. As a result, the cylinder 416 will be locked in the axial direction, but can be rotated when the key element 514 is fully inserted.
The key element 514 can only be fully inserted by depressing the handle 502 towards the locking mechanism 500 to overcome the force of the spring 516. Thus, the locking mechanism remains locked from turning until the key is inserted into the second locking mechanism 404 or until the handle 502 is pressed and rotated.
As a result, if the cracker retrieves the second actuator 404, he will not be able to easily turn the cam 406. First, the blocking element 492 will block access to the tooth 474 of the cam. Secondly, the cam 406 cannot be rotated until the handle 502 is biased towards the lock, which cannot be done from the outside.
It should be understood that the invention also covers other embodiments.
For example, the handle can be designed so that it only protrudes in a certain angular position corresponding to the locking of the lock. In all other positions, it is held inside the door to overcome the force of the spring 516.
Moreover, various features of the invention can be used individually or in combination to obtain an improved locking mechanism.
To increase the strength of the castle, its various components can be made not from traditional materials, such as brass, but from materials such as high-strength steel, Kevlar and composites.
