Detailed Description of the Preferred Embodiments

First, FIG. 1 is shown showing a mortise lock 10 constructed and operative in accordance with a preferred embodiment of the present invention.

Mortise lock 10 preferably includes a case 12, which is provided by a lock cylinder 14 acting as a key or by bolt follower 19 (shown in FIGS. 2 and 3). It houses a locking mechanism actuated by a handle 16 that is snapped into a square spindle hole 18. The details of the locking mechanism and its operation made by the locking cylinder 14 and the handle 16 are well described below. Mortise lock 10 is preferably a plurality of bolt locks, for example consisting of a plurality of locking bolts and / or latches. Although the locking bolt and the latch are employed in the present invention, the illustrated mortise lock 10 is designed to protrude from the face plate 28, the latch bolt 20 having a secondary latch 22, the square bolt 24 and The dead ball latch 26 is included. Furthermore, the specific embodiment shown includes two locking bolts 30 and 32 so configured to move vertically in the side of the standing door, and a locking bolt 34 configured to move horizontally in the side of the standing door. It includes. The locking bolts 20, 24, 30, 32 and 34 can be applied to various locking hardware installed in the door, which is used to lock the door. Such hardware is well known in the art and therefore no further explanation is necessary to one skilled in the art.

Mortise lock 10 is preferably provided with two handles 16, one of which is installed on both sides of the door (not shown). As is well known in the art, the handle on the inside of the door (eg, a side in a building) can typically be moved to operate the door locking mechanism. On the other hand, the outside handle of the door (for example, the outer side of the building) may or may not move depending on the particular choice. In the present invention the outer handle is selectively movable or immovable, the selection being achieved by means of the toggle 36 which is mechanically connected to the bolt follower 19. Toggle 36 acts like a clutch: the bolt follower 19 is connected or disconnected from the locking mechanism by the proper rotation of the toggle 36. This may be further explained below with respect to FIG. 5.

2, 3, and 4 showing the locking mechanism of the mortise lock 10 are as follows. The locking mechanism preferably comprises a gear wheel 38 optionally connected with a toothed bolt throw wheel 40 as described below. The gear wheel 38 is preferably generally coaxial with the bolt actuating wheel 40. Bolted wheel 40 is engaged with spur gear 42 (FIGS. 2 and 4), which is rotated by the rotation of a suitable locking cylinder 14 (lock cylinder 14 is spur gear in FIGS. 2 and 4). (42) omitted to highlight). For each locking bolt 24, 30, 32 and 34 the bolt actuating wheel 40 has a radial groove 44 therein which is provided in the corresponding one of the locking bolts 24, 30, 32 and 34. The pin 46 attached thereto is stored. As the pinion gear 42 rotates in the direction of the arrow 48 (FIG. 4), the bolt actuating wheel 40 rotates in the direction of the arrow 50, thereby moving the pin 46 in the groove 44 direction. And move the locking bolts 24, 30, 32 and 34 to the open position shown in FIG. Therefore, the locking bolts 24, 30, 32 and 34 are all operable by the key-operated locking cylinder 14.

A feature of the present invention is that the locking bolts 24, 30, 32 and 34 engage the connector of the locking mechanism of the mortise lock 10 in a modular manner, ie the case The lock bolt is installed in the case 12 in a modular manner without disassembling the case 12. Several lock bolts may be installed in the lock 10 and other lock bolts may be omitted if desired. The locking bolts 24, 30, 32 and 34 can optionally be connected or disconnected to the rest of the locking mechanism without disassembling the case 12. These features are achieved simply by attaching the locking bolt to the bolt-throw wheel and removing the pin 46 accessible through an access hole in the front or rear of the case 12. Can be. In addition, after removing the particular pin 46, any of the locking bolts may be reinstalled in the case 12 in the other direction. For example, the position of the locking bolt may be changed or it may be inverted to abut the other side of the case 12.

The operation of the latch bolt 20 and the auxiliary latch 22 by the lock cylinder 14 will now be described. The latch bolt 20 and the auxiliary latch 22 are preferably attached to the spring-loaded support element 52 by the spring 54 (FIG. 3). The support element 52 has a notch 56 that engages the tongue 58 of the latch lever 60. Two pins 62, 64 are fixedly attached to the latch lever 60. Pin 62 plays an important role in the operation of latch bolt 20 and auxiliary latch 22 as described in the following paragraphs. The importance of the pin 64 is in operating the dead bolt latch 26 as described further below. The latch lever 60 rotates around the rotation shaft 65.

Now additionally will be described with respect to FIG. The bolt-operated wheel 40 has a hooked groove 66 in the form of a "noose" that engages the pin 62. Rotation of the spur gear 42 in the direction of the arrow 48 causes the bolt-operated wheel 40 to rotate in the direction of the arrow 50 so that the hooked recess 66 is pin 62. Interlock with. The bent groove 66 in contact with the pin 62 generally causes the latch lever 60 to rotate about the rotation axis 65 in the direction of the arrow 68 (FIG. 3) so that the support element 52 in the direction of the arrow 68. Moves. Since the gold 56 of the support element 52 is engaged with the catch 58 of the latch lever 60, the movement of the support element causes the latch bolt 20 and the auxiliary latch 22 in the case 12 to be moved to FIG. 4. Move it to the unlocked position shown. Therefore, the latch bolt 20 and the auxiliary latch 22 are operated by the key-operated locking cylinder 14.

Operation of the dead bolt latch 26 is now described with particular reference to FIG. 5. The dead bolt latch 26 preferably includes a clasp 70 adjacent to one side 74 of the brake lever 72 in the position illustrated in FIG. 5. Dead bolt latch 26 is preferably biased by a biasing device, such as flat spring 75. The brake lever 72 rotates around the axis of rotation 76 and includes a stopping face 78. When the clasp 70 is adjacent to the face 74 of the brake lever 72, the brake lever 72 rotates so that the pin 64 is not adjacent to the stop surface 78 as shown in FIG. In this position, the face 74 of the brake lever 72 is biased against the clasp 70 by a biasing device such as a spring 80.

When the dead bolt latch 26 moves inward in the direction of the arrow 82 (the position shown in FIG. 4), the spring catch 70 slides against the face 74 so that the braking lever 70 is moved by the spring 80. The stop surface 78 rotates about the Q position (indicated by an imaginary line in FIG. 5) adjacent to the flat surface of the pin 64 so as to rotate in the direction of arrow 84. In this position, the pin 62 cannot move by the bent groove 66 of the bolt-actuated wheel 40 because the pin 64 cannot move past the stop face 78 of the brake lever 72. Therefore, the latch lever 60 cannot move in the direction of the arrow 68 (FIG. 3), and the latch bolt 20 and the auxiliary latch 22 cannot push outward to the unlocked position shown in FIG. Can function as a dead bolt.

The function of the dead bolt can be negated by turning the spur gear 42 into the key-operated locking cylinder 14 as described. The brake lever 72 is preferably provided with a pin 73 extending towards the bolt-operated wheel 40. The bolt-operated wheel 40 consists of a cam face 71 which is slightly radially outward of the general circumference of the wheel 40. When the spur gear 42 rotates due to the key-operated locking cylinder 14, the bolt-operated wheel 40 turns in the direction of the arrow 50. The bolt-operated wheel 40 has a cam face 71 that pushes the pin 73 before the bent groove 66 abuts the pin 62 so that the brake lever moves in the direction of the arrow 63 around the rotation axis 76. , Pin 64 and latch lever 60 to rotate out of Q position. This negates the function of the dead bolt. The bent groove 66 can now engage the pin 62 and move the latch bolt 60 and the secondary latch 22 to the unlocked position shown in FIG. 4.

It should be noted that the key-operated locking cylinder 14 may include a double cylinder that may be installed only on one side of the door or optionally installed on both sides of the door. The function of the dead bolt can be negated by the operative rotation of one or two key-operated locking cylinders 14. The function of the dead bolt can also be negated by turning the handle 16 as further described below. As described below, the ability of the handle 16 to negate the function of the dead bolt may be optional, i.e., whether the user can negate the function of the dead bolt. In the illustrated embodiment, the freedom of choice to selectively deny the function of the dead bolt with the handle 16 is provided on only one side of the door, but the freedom of choice may be provided on both sides of the door. However, the handles on both sides of the door can always return the latch bolt 20 and the auxiliary latch 22 to the unlocked position shown in FIG.

5 also illustrates a mechanism associated with a toggle 36. In the position illustrated in FIG. 5, the face 86 of the toggle 36 is biased against the detent 88, and the toggle 36 rotates about the axis of rotation 90. As the toggle 36 rotates around the axis of rotation 90 in the direction of the arrow 92, another face 94 is returned relative to the detent 88 so that the detent 88 generally moves in the direction of the arrow 96. Toggle follower 98 is pushed. The toggle follower 98 then moves in the direction of the arrow 96 and the dog 100 of the toggle follower 98 engages with the gold 102 formed in the bolt follower 19. When the clamp 100 is fixedly engaged with the gold 102, the bolt follower 19 cannot rotate. In this locked position, the handle 16 cannot rotate to do any operation with respect to the locking mechanism of the lock 10. This orientation is commonly used for the outer handle of the door. Conversely, when the handle 16 falls away from the bolt follower 19, i.e., the engagement of the clamp 100 with respect to the gold 102 (the position illustrated in FIG. 5) falls, the handle 16 is locked out of the lock 10. The locking mechanism can be rotated to operate.

The operation of the latch bolt 20 and the auxiliary latch 22 by the handle 16 will now be described. The bolt follower 19 includes a cam 104 arranged to push the latch follower 106. The latch follower 106 includes a geared arm 110 that rotates about the axis of rotation 108 and engages with a gear wheel 38. Latch follower 106 is preferably biased against the inner surface of case 12 by a biasing device such as spring 112. As can be seen in FIGS. 2, 3 and 5, the pin 114 is fixed to the distal end of the gear arm 110. In the position illustrated in FIG. 5, the pin 114 is adjacent to the surface of the inner cutout 116 formed in the latch lever 60.

When the handle 16 rotates in the direction of arrow 118 (FIG. 4), cam 104 pushes latch follower 106 generally in the direction of arrow 120. This causes the pin 114 to rotate the latch lever 60 around the axis of rotation 65 in the direction of the arrow 68 (FIG. 3) such that the support element 52 also moves in the direction of the arrow 68. As already mentioned, the movement of the support element 52 assists the latch bolt 20 and the auxiliary latch 22 because the gold 56 of the support element 52 engages the clasp 58 of the latch lever 60. Move to the unlocked position shown in 4. Therefore, the latch bolt 20 and the auxiliary latch 22 are operable by the handle 16.

In addition to FIG. 5, a description will now be made of FIG. 6. The gear wheel 38 is preferably connected with the bolt-actuated wheel 40 by means of a pin 122. The pin 122 projects radially outward from a threaded fastener, such as a set screw 124. The set screw 124 is screwed into a hub 125 in which a bolt-operated wheel 40 is fixedly installed around it. The gear wheel 38 has an arcuate groove 126. 6 illustrates the pin 122 in the groove 126. By properly rotating the set screw 124, the pin 122 can move from the arcuate groove 125 (downward in FIG. 6). When the pin 122 is received in the groove 126, rotation of the handle 16 in the direction of the arrow 118 causes the cam 104 to generally push the latch follower 106 in the direction of the arrow 120. , In turn, causes the gear wheel 38 and the bolt-operated wheel 40 to rotate in the direction of the arrow 50. Since the pin 122 is adjacent to the groove 126, the bolt-actuated wheel 40 rotates with the gear wheel 38, thereby connecting the bolt-actuated wheel 40 to the gear wheel 38. . As mentioned above, the rotation of the bolt-operated wheel 40 in the direction of the arrow 50 causes the pin 46 to move into the radially inner groove 44 to bring the lock bolt 24 to the unlocked position shown in FIG. 4. 30, 32 and 34). Therefore, when the pin 122 is received in the groove 126, the rotation of the handle 16 in the direction of the arrow 118 serves to open quickly: as well as the latch bolt 20 and the auxiliary latch 22. The locking bolts 24, 30, 32 and 34 are all operable by the handle 16, whether partially locked or not (about 30 ° typically, but not necessarily).

If the pin 122 is not received in the groove 126, the bolt-actuated wheel 40 falls off the gear wheel 38. In this case, the rotation of the handle 16 in the direction of the arrow 118 does not operate the lock bolts 24, 30, 32 and 34, but only the latch bolt 20 and the auxiliary latch 22.

When the quick opening function is selected, rotation of the handle 16 negates the dead bolt function of the brake lever 72 and the dead bolt latch 26 as described. The brake lever 72 is preferably in the position illustrated in FIG. 5 and provides a clasp 77 in contact with the bolt follower 19. Rotation of the bolt follower in the direction of arrow 118 (FIG. 4) pushes the clasp 77 so that the brake lever 72 rotates outward in the Q position in the direction of the arrow 63 with respect to the rotational axis 76 to pin 64 ) And latch lever (60). This negates the function of the dead bolt. Only after the dead bolt function has been released is the continuous rotation of the bolt follower 19 by the handle 16 returning the pin 114 relative to the internal cutout 116 so that the latch lever 60 is generally rotating shaft 65. Rotates in the direction of arrow 68 (FIG. 3), which causes the support element 52 to move in the direction of arrow 68 and also to open the latch bolt 20 and the auxiliary latch 22 shown in FIG. Move to position

As described above, the key-operated locking cylinder 14 may comprise a double cylinder installed only on one side of the door or optionally on both sides of the door. Alternatively, a lock cylinder can be installed on both sides of the door, which means that even if another key is inserted and turned into the lock cylinder on the other side of the door, the lock bolt can be inserted and rotated into one lock cylinder installed on one side of the door. The lock 10 is operated by moving the latch bolt 20 and the auxiliary latch 22. This feature, described below with reference to FIGS. 7-14, may be particularly useful for locks installed in public places, such as hotels, where a person in a room may be required to enter the room even if the person in the room has inserted and rotated a key in the inner lock. .

A pair of locks mounted on both sides of the mortise lock 10 (which is understood to be the same as the lock of FIG. 1, but shown in a simplified form for clarity), which is now constructed and operative in accordance with a preferred embodiment of the present invention. Reference is made to FIGS. 7-14 which illustrate the cylinder 200. Each locking cylinder 200 preferably includes a pin tumbler 202 rotatably mounted to an inner bore 204. A gear clutch 206 is slidably mounted to the inner diameter 204 between the cover 208 attached to the end of the lock cylinder 200 and the end of the pin tumbler 202. A pair of springs 210 are preferably mounted between the cover 208 and the ends of the gear clutch 206, which typically move the gear clutch 206 toward the key insert end of the pin tumbler 202. . As shown in FIG. 8B, the pin tumbler 202 and the gear clutch 206 are sufficiently locked by the key 212 being inserted into the pin tumbler 202 to push the gear clutch 206 against the spring 210. It is arranged to push the gear clutch 206 protruding from the 200.

The gear clutch 206 may engage with a correspondingly formed hole 214 of the link-hub 216 when projecting from the lock cylinder 200. The link-hub 216 is attached to the spur gear 42 (as best seen in FIGS. 12-14) described above. When the gear clutch 206 is engaged with the link-hub 216, the rotation of the gear clutch 206 rotates the spur gear 42 from above by the proper rotation of the key 212 inserted into the pin tumbler 202. Activate lock 10 as described. As shown in FIG. 12, the hole 214 on one side of the spur gear 42 is a mirror image of the hole opposite to the spur gear 42.

Both link-hubs 216 are rotatably mounted to the lock case 12, as shown in FIG. 10 (one link-hub 216 is shown to the left of the lock 10 in FIG. 7). As shown in FIGS. 10 and 13, a spring 218 is preferably mounted between the two link-hubs 216 which usually allows the two link-hubs 216 to be spaced from each other. Both link-hubs 216 are preferably mounted on a common shaft 217 (FIG. 13).

The operation of the locking cylinder 200 will now be described. A key 212 is inserted into one lock cylinder 200, pushing the gear clutch 206 out of the lock cylinder 200 as shown in FIG. 8B. In this state, as shown in the lower locking cylinder 200 of FIG. 10 (omitting the key 212 for clarity of FIG. 10), the gear clutch 206 enters and corresponds to the corresponding link-hub 216. Combine with The lock 10 can be activated by turning the key 212 to rotate the link-hub 216 and the spur gear 42. The spring 218 strikes the other link hub 216 (at the top of FIG. 10) against the gear clutch 206 (at the top of FIG. 10) of the opposite locking cylinder 200. As mentioned above, the upper link-hub 216 is not engaged with the gear clutch 206 because the holes 214 are mirrored relative to one another.

Along with the first key 212 being inserted into the lower locking cylinder 200 and rotating, the second key 212 can be inserted into the opposite locking cylinder 200 (the one at the top of FIG. 10). At this time, as described above, the hole 214 of the upper link-hub 216 is not arranged to engage the upper gear clutch 206. However, it is possible to rotate the pin tumbler 202 of the upper lock cylinder 200 by turning the key 212 to align the upper gear clutch 206 with the hole 214 of the upper link-hub 216, At this time, the spring 218 raises the upper link-hub 216 upward in FIG. 10 so that the hole 214 engages with the upper gear clutch 206. Once the upper link-hub 216 is engaged with the upper gear clutch 206, although there is a first key in the upper locking cylinder 200, the second key now rotates both link-hubs 216 to spur. The gear 42 can be rotated and the lock 10 can be activated.

It will be understood by those skilled in the art that the present invention is not limited to those specifically shown and described above. Rather, the scope of the present invention includes both combinations and subcombinations of the above described features as well as improvements and modifications that do not belong to the prior art that may occur to those skilled in the art upon reading the foregoing description.
