DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference is now made to FIG. 1, which illustrates a mortise lock 10 constructed and operable in accordance with a preferred embodiment of the present invention.

The mortise lock 10 preferably includes a frame 12 in which a locking mechanism is provided, actuated by a key cylinder 14 operated by a key, or by a handle 16 engaged with a generally square spindle hole 18 of the shutter pusher 19 (shown in FIGS. 2 and 3 ) Details of the locking mechanism and its operation using the locking cylinder 14 and the handle 16 are described here below. The mortise lock 10 is preferably a lock with a large number of shutters, i.e. it includes a plurality of locking shutters and / or latches. Although any number of locking bolts or latches may be used in the present invention, in the illustrated embodiment, the mortise lock 10 includes a locking bolt 20 having an auxiliary latch 22, a rectangular (solid bar) shutter 24, and a blind shutter latch 26 that are designed to extend from the end 28 In addition, the illustrated embodiment includes two locking shutters 30 and 32 oriented for vertical movement with respect to a vertically located door, and a locking shutter 34 oriented suspended for horizontal movement with respect to the vertically located door. The locking bolts 20, 24, 30, 32 and 34 can engage with various locking means installed in the door and used to close the door, and such locking means are very well known in this field, so that the further description is not necessary for specialists in this area.

The mortise lock 10 is preferably provided with two handles 16, one on each side of the door (not shown). As is well known in the art, the handle on the inside of the door (i.e., on the inside of the room) is usually movable to actuate the locking mechanism of the door, while the handle on the outside of the door (i.e. outside the room) ) may be movable or motionless, depending on the specific application. In the present invention, the external handle is selectively movable or stationary, the selection being made by means of an articulated lever 36 mechanically connected to the shutter pusher 19. The crank lever 36 acts like a latch: by appropriate rotation of the crank lever 36, the shutter pusher 19 either connects or disconnects with the locking mechanism, as described below with reference to FIG. 5.

Reference is now made to FIG. 2, 3 and 4, which illustrate the locking mechanism of the mortise lock 10. The locking mechanism preferably includes a gear 38 selectively coupled, as described below, with a gear 40, providing a shutter travel. The gear wheel 38 is preferably coaxial to the wheel 40, providing a stroke of the shutter. The shutter wheel 40 engages the spur gear 42 (FIGS. 2 and 4), which rotates due to the corresponding rotation of the lock cylinder 14 (the lock cylinder 14 is not shown in FIGS. 2 and 4 for clarity, so that see the spur gear 42). For each locking shutter 24, 30, 32 and 34, the wheel 40, providing the shutter travel, has a radial groove 44 made in it, in which a pin 46 is mounted, attached to the corresponding one of the locking shutters 24, 30, 32 and 34. When rotating gear gear 42 in the direction of arrow 48 (Fig. 4), the shutter wheel 40 is rotated in the direction of arrow 50, thereby causing the pins 46 to move radially inside the grooves 44 and cause the locking shutters 24, 30, 32 and 34 in the open position shown in FIG. 4. Thus, all the locking valves 24, 30, 32 and 34 are moved using the locking cylinder 14, which operates with a key.

A specific feature of the present invention is that the locking latches 24, 30, 32 and 34 are engaged with the tail of the locking mechanism of the mortise lock 10 in a modular form, i.e. the locking shutters are mounted in the frame 12 modularly without dismounting the frame 12. If desired, any number of locking shutters can be installed in the frame 12 and the other locking shutters can be removed. In addition, the locking bolts 24, 30, 32 and 34 can be selectively connected or disconnected from the tail of the locking mechanism without dismantling the frame 12. These properties are achievable by simply removing the pins 46 that attach the locking bolts to the wheel 40, providing a stroke of the shutter, and access to the pins 46 is possible by accessing the holes on either the front or rear end of the frame 12. In addition, after removing the specific pin 46, any locking bolt can be reinstalled in the frame 12 in the other orientation. For example, the location of the locking shutters can be interchanged or the locking shutters can be inverted to make the other side of the end of the frame 12.

The movement of the locking bolt 20 and the auxiliary latch 22 with the locking cylinder 14 is now described. The locking bolt 20 and the auxiliary latch 22 are preferably fastened to the supporting member 52 spring-loaded by the spring 54 (FIG. 3). A recess 56 is made in the support member 52, which engages with the tongue 58 of the locking lever 60. A pair of pins 62 and 64 are firmly attached to the locking lever 60. The pin 62 plays a role in moving the locking bolt 20 and the auxiliary latch 22, as described in the next section. The role of the pin 64 is to actuate the blind shutter latch 26, as shown below. The locking lever 60 rotates about an axis 65.

Turning now again to FIG. 5. In the wheel 40, providing the shutter travel, a groove 66 is made in the form of a hook, designed to "catch", i.e. to engage with pin 62. Rotating the spur gear 42 in direction of arrow 48 causes the shutter wheel 40 to rotate in direction of arrow 50, thereby causing hook-shaped groove 66 to mesh with pin 62. Groove-shaped groove 66 the hook, which abuts against the end and moves the pin 62, causes the locking lever 60 to rotate mainly in the direction of the arrow 68 (Fig. 3) about the axis 65, thereby moving the support element 52 also mainly in the direction of the arrow 68. Since reference recess 56 element 52 is engaged with the tab 58 of the locking lever 60, the movement of the support element 52 brings the locking bolt 20 and the auxiliary latch 22 inside the frame 12 in the open position shown in FIG. 4. Thus, the locking shutter 20 and the auxiliary latch 22 are moved by a locking cylinder 14, which operates with a key.

Now with specific reference to FIG. 5, the operation of the blind shutter latch 26 is described. The blind shutter latch 26 preferably has a tongue 70, which in the position illustrated in FIG. 5, abuts against the end face 74 of the brake lever 72. The blind shutter latch 26 is preferably biased by a biasing device, such as a flat spring 75. The brake lever 72, which rotates around the axis 76, has a bounding face 78. When the tongue 70 abuts the end end 74 brake lever 72, the latter is rotated so that the pin 64 is not adjacent to the boundary face 78, as shown in FIG. 5. In this position, the end face 74 of the brake lever 72 is displaced with respect to the tongue 70 by a biasing device such as a spring 80.

When the blind shutter latch 26 moves inward in the direction of the arrow 82 (the position shown in FIG. 4), the spring-loaded tab 70 slides from the end 74 and the spring 80 causes the brake lever 72 to rotate in the direction of the arrow 84, as a result of which the restriction face 78 rotates to position O (shown by the conditional lines in Fig. 5), directly adjacent to the flat face of the pin 64. In this position, since the pin 64 cannot pass past the bounding face 78 of the brake lever 72, the pin 62 cannot be moved by a groove 66 in the shape of yuchka wheels 40 providing the shutter stroke. Therefore, the locking lever 60 cannot be moved in the direction of the arrow 68 (FIG. 3), and the locking bolt 20 and the auxiliary latch 22 cannot be retracted from the outside to the open position shown in FIG. 4, what is achieved by the function of the blind shutter.

The blind shutter function can be negated by turning the spur gear 42 by the locking cylinder 14, which operates with a key, as described below. The brake lever 72 is preferably provided with a pin 73, which is oriented in the direction of the wheel 40, providing the stroke of the shutter. The shutter wheel 40 is made with a cam surface 71 that extends radially slightly beyond the main perimeter of the wheel 40. When the spur gear 42 is rotated by a locking cylinder 14 using a key, the shutter wheel 40 rotates in the direction of the arrow 50. The shutter wheel 40 is configured so that before the hook-shaped groove 66 touches pin 62, the cam surface 71 collides with pin 73, thereby causing the brake the th lever to rotate around axis 76 in the direction of arrow 63 from position O so that pin 64 and locking lever 60 are released. This negates the blind shutter function. The hook-shaped groove 66 can now engage with the pin 62 and move the locking lever 60 to bring the locking bolt 20 and the auxiliary latch 22 to the open position shown in FIG. 4.

It should be emphasized that the key lock cylinder 14 can be mounted on only one side of the door, or alternatively it can include a double cylinder that can be installed on both sides of the door. The function of the blind shutter can be nullified by the working rotation of one or both cylinders 14, operating with a key. The blind shutter function can also be nullified by turning the knob 16, as described further below. As described below, the ability of the handle 16 to negate the shutter function is selective, that is, the user can choose whether to use the shutter function or not use the handle 16. In the illustrated embodiment, the choice to reject the shutter function with the handle 16 is only provided on one side of the door, but it’s clear that a choice can be made for both sides of the door. However, the handles on both sides of the door can always bring the locking bolt 20 and auxiliary latch 22 to the open position shown in FIG.

4.

FIG. 5 also illustrates the mechanism associated with the crank arm 36. In the position illustrated in FIG. 5, the face 86 of the crank arm 36 is offset with respect to the stopper and the crank arm 36 is rotated around the axis 90. When the crank arm 36 rotates around the axis 90 in the direction of arrow 92, the other face 94 comes into contact with the stop 88, thereby causing the stop 88 to move, mainly in the direction of arrow 96 toward the crank arm pusher 98. Thus, the crank lever pusher 98 moves in the direction of arrow 96, causing the dog 100 of the crank lever pusher 98 to engage with its corresponding recess 102 made in the shutter pusher 19. As soon as the dog 100 is fixedly aligned with the recess 102, the shutter pusher 19 will not be able to rotate. In such a locked position, the handle 16 cannot be rotated in order to perform any action associated with the locking mechanism of the lock 10. This orientation is usually used for the outer door handle. On the contrary, when the handle 16 is disconnected from the shutter pusher 19, i.e. when the dog 100 is engaged with the recess 102 (the position illustrated in FIG. 5), the handle 16 can be rotated to actuate the locking mechanism of the lock 10.

Now described is the movement of the locking shutter 20 and the auxiliary latch 22 with the handle 16. The pusher 19 of the shutter has a cam 104, which is set to press the pusher 106 of the latch. The latch pusher 106, which is rotated about an axis 108, includes a gear lever 110 that engages with the gear 38. The latch pusher 106 is preferably biased relative to the inner surface of the frame 12 by an biasing device such as a spring 112. As can be seen in FIG. 2, 3 and 5, the pin 114 is secured to the extreme end of the gear lever 110. In the position illustrated in FIG. 5, the pin 114 is adjacent to the surface of the internal cutout 116 formed in the locking arm 60.

When the handle 16 is rotated in the direction of arrow 118 (FIG. 4), the cam 104 presses the latch pusher 106, mainly in the direction of arrow 120. This causes the pin 114 to turn the locking lever 60, mainly in the direction of arrow 68 (FIG. 3) about an axis 65, thereby moving the support member 52 also mainly in the direction of the arrow 68. As mentioned earlier, since the recess 56 in the support member 52 is engaged with the tongue 58 of the locking lever 60, the movement of the supporting member 52 causes the locking bolt 20 and auxiliary latch 22 into the open the position shown in FIG. 4. Thus, the locking shutter 20 and the auxiliary latch 22 are moved by the handle 16.

In addition to FIG. 5, reference is now made to FIG. 6. The gear 38 selectively engages with the shutter wheel 40, preferably by means of a pin 122. The pin 122 extends radially outwardly from a threaded clip such as a locking screw 124. The locking screw 124 is screwed into a sleeve 125 on which the wheel is fixedly mounted 40, providing a shutter stroke. An arch-shaped groove 126 is formed in the gear 38. FIG. 5 illustrates the pin 122 in the groove 126. By appropriately rotating the locking screw 124, the pin 122 can be removed from the arcuate groove 126. When the pin 122 is mounted in the groove 126, rotating the handle 16 in the direction of arrow 118 causes the cam 104 to press the latch follower 106, generally in the direction of the arrow 120, which in turn causes the gear 38 and the shutter 40 to rotate in the direction of the arrow 50. The shutter 40 is rotated together with the gear 38 because the pin 122 is adjacent to the groove 126, thereby connecting the shutter wheel 40 to the gear 38. As mentioned above, rotation of the shutter wheel 40 in the direction of arrow 50 causes the pins 46 to move radially inward in the grooves 44 and causes the locking shutters 24, 30 32 and 34 to the open position of FIG. 4. Thus, when the pin 122 is installed in the groove 126, the rotation of the handle 16 in the direction of the arrow 118 performs the function of quick opening: the locking bolts 24, 30, 32 and 34, as well as the locking bolt 20 and the auxiliary latch 22 are all driven by partial rotation (usually, but not necessarily, about 30 °) of the handle 16, regardless of whether they were previously in a closed state or not.

When the pin 122 is not installed in the groove 126, the shutter wheel 40 is disconnected from the gear 38. In this case, the rotation of the handle 16 in the direction of the arrow 118 drives the locking bolt 20 and the auxiliary latch 22 and does not actuate the locking latches 24 , 30, 32, and 34.

Thus, the rotation of the handle 16 when the quick opening property is selected also negates the function of the blind shutter of the blind shutter latch 26 and the brake lever 72. The brake lever 72 is preferably performed with the tongue 77, which in the position illustrated in FIG. 5, is in contact with the shutter follower 19. The rotation of the shutter pusher in the direction of arrow 118 (FIG. 4) puts pressure on the tongue 77 and causes the brake lever 72 to rotate about an axis 76 in the direction of arrow 63 and from position O so that it releases pin 64 and locking lever 60. This negates blind shutter function. Only after the blind shutter function is abandoned, the further rotation of the shutter pusher 19 with the handle 16 brings the pin 114 to the inner cutout 116 so as to turn the locking lever 60, mainly in the direction of the arrow 68 (Fig. 3) around the axis 65, thereby moving the supporting element 52 also mainly in the direction of arrow 68, thereby bringing the locking bolt 20 and the auxiliary latch 22 to the open position shown in FIG. 4.

As indicated above, the key cylinder 14, which operates with a key, can be installed only on one side of the door or, alternatively, it may comprise a double cylinder, which is installed on both sides of the door. As a further alternative, the lock cylinders can be installed on both sides of the door, which allows the lock 10 to be operated when the key is inserted into one of the lock cylinders located on one side of the door, and by turning the key, the locking bolt 20 and the auxiliary latch 22 can be moved, even if another key is inserted and rotated in the lock cylinder on the other side of the door. This property, described below with reference to FIG. 7-14 can be especially useful for locks installed in public places, such as hotels, where it may be desirable to enter the room if the occupant entered the key into the lock from the inside and even turned the key.

Reference is now made to FIG. 7-14, which illustrate a pair of lock cylinders 200 mounted on opposite sides of the mortise lock 10 (illustrated in a simplified form for clarity, although it will be understood that this will be the same lock shown in Fig. 1) designed and operated in accordance with the preferred variant of the present invention. Each locking cylinder 200 preferably includes a pin reversing mechanism 202 rotatably mounted in the hole 204. The transmission clutch 206 is mounted to slide in the hole 204 between the end of the pin reversing mechanism 202 and the cover 208 protecting the end of the locking cylinder 200. A pair of springs 210 that preferably installed between the end face of the transfer clutch 206 and the cover 208, exerts normalized pressure on the transfer clutch 206 towards the end to enter the key of the pin reversible mechanism 202. As can be seen in FIG. 8B, the pin reversing mechanism 202 and the transmission clutch 206 are mounted so that the key 212 can be inserted into the pin reversing mechanism 202 and sliding the transmission clutch 206 against the springs 210, thereby moving the transmission clutch 206 sufficiently so that it protrudes from the lock cylinder 200 .

The transmission clutch 206, after it is withdrawn from the lock cylinder 200, can mate with the correspondingly made hole 214 of the connecting sleeve 216. The connecting sleeve 216 at 13 is attached to the spur gear 42 (as can be clearly seen in Fig. 12-14) described above . When the transmission clutch 206 is mated to the connecting sleeve 216, the rotation of the transmission clutch 206, by rotating the key 212 inserted into the pin reversing mechanism, rotates the spur gear 42 to engage the lock 10, as described above. As seen in FIG. 12, the hole 214 on one side of the spur gear 42 is a mirror image of the hole 214 on the opposite side of the spur gear 42.

Both connecting sleeves 216 are rotatably mounted in the lock frame 12, as seen in FIG. 10 (moreover, one connecting sleeve 216 is visible on the left side of the lock 10 in Fig. 7). As seen in FIG. 10 and 13, the spring 218 is preferably fastened between two connecting sleeves 216 that normally normalize the two connecting sleeves 216 from each other. Both connecting sleeves 216 are preferably secured to a common shaft 217 (FIG. 13).

The operation of the lock cylinders 200 is described below. The key 212 can be inserted into one of the lock cylinders 200, thereby moving the transfer clutch 206 so that it protrudes from the lock cylinder 200, as can be seen in FIG. 8B. In this position, as seen on the lower lock cylinder 200 of FIG. 10 (the key 212 is not shown for clarity in FIG. 10), the transmission clutch 206 enters and mates with the corresponding connecting sleeve 216. The key 212 can be rotated to rotate the connecting sleeve 216 and the spur gear 42 and actuate the lock 10. On the other connecting sleeve 216 (the upper one in FIG. 10) is exerted pressure towards the transfer clutch 206 of the opposite lock cylinder 200 (the upper one in FIG. 10) by the spring 218. Since, as mentioned above, the holes 214 are mirror images of each other, the upper connection the sleeve 216 does not mate with the transmission clutch 206.

Even if the first key 212 is inserted and rotated in the lower lock cylinder 200, the second key 212 can be inserted into the opposite lock cylinder 200 (the upper one in FIG. 10). As mentioned above, at this stage, the hole 214 of the upper connecting sleeve 216 is not aligned to mate with the upper gear coupling 206. However, the key 212 can be rotated to rotate the pin reversing mechanism 202 of the upper lock cylinder 200 so as to align the upper gear coupling 206 with the hole 214 of the upper connecting sleeve 216, as a result of which the spring 218 presses up on the upper connecting sleeve 216, referring to FIG. 10, so that the hole 214 mates with the upper transmission sleeve 206. Once the upper connection sleeve 216 is aligned with the upper transmission sleeve 206, the second key can now rotate both of the connecting sleeve 216 and thus rotate the spur gear 42 and actuate the lock 10. despite the presence of the first key in the upper lock cylinder 200.

Specialists in this field should take into account that the present invention is not limited to what has been specifically shown and described above. Rather, the scope of the present invention includes both combinations and subcombinations of the features described above, as well as their modifications and variations that may be experienced by a person skilled in the art while reading the above description and which are not available in the prior art.
