DETAILED DESCRIPTION OF THE INVENTION

Referring now to Figure 1, parts and functions of a recessed lock 10 according to a preferred embodiment of the present invention will be described.

Preferably, the recessed lock 10 includes a lock box 12 with a lock mechanism operated by a key via a lock cylinder 14 or a crank 16 through which the nut slider 19 is controlled via the square hole of the nut 18 (see Figures 2 and 3). A detailed description of the lock mechanism and its control by the lock cylinder 14 and the handle 16 is given below. The recessed lock 10 preferably has the function of a lock with multiple locking elements, i.e., includes a plurality of locking bolts or latches. Although the lock of the present invention may be provided with any number of latches or latches, the illustrated embodiment of the embedded lock 10 includes a latch 20 with an auxiliary latch 22, a right latch 24 and a dead latch 26 that protrude from the front plate 28. vertically the bars of the auxiliary locks 30 and 32 and the horizontally the bars of the auxiliary lock 34. The shut-off elements and the draw-bars 20, 24, 30, 32 and 34 can further control a variety of shut-off mechanisms installed in the door. These locking mechanisms are well known in the art and do not require a detailed description of the skilled person.

The recessed lock 10 preferably comprises two handles 16 inserted into the lock from both sides (not shown). As is common in the art, the handle on the inside of the door (i.e., the inside of the building) is compressible and serves to control the door closing mechanism, while the handle on the outside of the door (i.e., the outside of the building) may or may not be compressible. In the present invention, the outer handle may be optionally compressible or incompressible, the selection being made by a switch 36 that is mechanically connected to the nut slider 19. The switch 36 functions as a clutch: by rotation. * The switch 36 can be used to slide the nut slider 19 to connect it. or detach from the closure mechanism as further described in the description of Figure 5.

The description will now refer to Figures 2, 3 and 4, in which the latch lock mechanism 10 is shown. The latch mechanism preferably consists of a gear 38 which is optionally coupled (as described below) to a pulse gear 40. the wheel 38 is preferably substantially coaxial to the pulse wheel 40. The teeth of the pulse wheel 40 fit into the teeth of the pinion 42 (Figures 2 and 4), which rotate with rotation of the lock cylinder 14. (Lock cylinder 14 is omitted in Figures 2 and 4 so that the pinion 42) can be shown. In the pulse wheel 40 there are four radial grooves 44 for the closure elements 24, 30, 32 and 34 into which the tips 46 are inserted, fixed to the closure elements 24, 30, 32 and 34. Due to rotation of the pinion 42 in the direction of arrow 48 4), the pulse wheel 40 rotates in the direction of the arrow 50, which then causes radial movement of the spikes 46 in the grooves 44, followed by sliding the closure elements 24, 30, 32 and 34 to the unlocked position (Figure 4). The lock closure elements 24, 30, 32 and 34 are thus key operable by the lock cylinder 14.

A specific feature of the present invention is that the closure elements 24, 30, 32, and 34 are operatively connected to the other parts of the recessed lock mechanism 10 in a modular manner. Any number of closure elements may be installed in the lock 10, other elements may be omitted as required. Furthermore, the closure elements 24, 30, 32 and 34 can be optionally connected or disconnected from the other elements of the closure mechanism without having to prevent disassembly of the box 12. This feature is achieved simply by removing the spikes 46 which connect the closure elements to the pulse wheel 40 The prongs 46 can be accessed through openings in the front or back of the housing 12. In addition, the closure elements can be assembled in the housing 12 in a new way and with a different orientation after removal of the corresponding prong 46. For example, the closure elements may be interchanged, or may be set in a different direction in the housing 12.

We now describe a method of operating the pawl 20 and the pawl 22 by the lock cylinder 14. The pawl 20 and the pawl 22 are preferably resiliently coupled to the support member 52 by a spring 54 (Figure 3). In the support member 52 is a notch 56 into which a tab is engaged. 58 of the gear lever 60. The gear lever 60 includes a fixed pair of spikes 62 and 64. The tip 62 is operated by a latch 20 and an auxiliary lever 8 8 B 8 8 8 8 B B 8 · · ··· 6 BO · 6 b · e 8888 88 8888 88 8 latch 22 (see next paragraph). The tip 64 is related to the function of the deadbolt 26. The gear lever 60 rotates on the pivot pin 65.

The description will now refer to Figure 5. The pulse wheel 40 is provided at its edge with a recess 66 adapted to receive the tip 62 in its shape. Rotation of the pinion 42 in the direction of arrow 48 results in rotation of the pulse wheel 40 in the direction of arrow 50 and subsequently. engaging the tip 62 by the recess 66 and moving it with the gear lever 60 generally in the direction of the arrow 68 (FIG. 3) around the pivot pin 65. This will displace the support element 52 generally in the direction of the arrow 68. notch 56 of the support member 52, the movement of the support member 52 causes the latch 20 and the latch 22 to slide into the housing 12 (i.e., the unlocked position in Figure 4). The latch 20 and the auxiliary latch 22 are in this way actuated by a key by means of a lock cylinder 14.

Now, the function of the deadbolt 26 will be described with reference to Figure 5. A preferred component of the deadbolt 26 is a tab 70 which in Figure 5 abuts the face 74 of the restraining lever 72. The deadbolt is preferably angled by a tilting device such as a flat spring 75. rotates around the pivot pin 76 and includes a detent 78. When the tab 70 abuts the face 74 of the detent lever 72, the detent lever 72 is rotated so that the tip 64 does not abut the detent 78 as shown in Figure 5. the face 74 of the retaining lever 72 is angled against the tongue 70 by a tilting device such as a spring 80.

Upon insertion of the deadbolt 26 inwardly into the housing 12 in the direction of arrow 82 (position shown in Figure 4), the resilient tongue 70 slides off the face 74 and the spring 80 causes the retaining lever 72 to rotate in the direction of arrow 84; it rests against the tip 64. In this position, the tip 64 cannot slide beyond the stop 78 of the retaining lever 72 and the tip 62 cannot subsequently be engaged and moved by the recess 66 of the pulse wheel 40. The gear lever 60 cannot then move in the auxiliary pawl 22 cannot be pushed from the outside into the unlocked position in Figure 4, so that they perform the function of a dead pawl.

We will now describe the disengagement of the deadbolt by turning the pinion 42 with the key through the lock cylinder 14. The retaining lever 72 is preferably provided with a spike

73 that protrudes toward the pulse wheel 40. There is a protrusion 71 in the pulse wheel 40.

which protrudes slightly outward from the peripheral surface of the pulse wheel 40. By turning ··

The pinion 42 of the lock cylinder 14 causes the pulse wheel 40 to rotate in the direction of the arrow 50. The pulse wheel 40 is adapted such that the recess 71 rests against the tip 73 prior to engaging the tip 62 with recess 66. This results in rotation of the retaining lever 72 around the pivot. 76 in the direction of the arrow 63 from the position Q so that the tip 64 and the gear lever 60 are released. The dead latch function is thereby canceled. The tip 62 can now be engaged by the recess 66 and moved by the gear lever 60 such that the latch 20 and the auxiliary latch 22 are slid into the unlocked position shown in Figure 4.

It should be emphasized that the key operated cylinder of the lock 14 may be installed on only one side of the door, or alternatively may be in the form of a double cylinder installed on both sides of the door. The dead latch function can be canceled by rotating one or both of the key operated cylinders of the lock 14 and also by depressing the handle 16 as described below. The possibility of canceling the dead-latch function by means of the handle is optional, i.e. the user can choose whether or not to cancel the dead-latch function by means of the handle 16. In the embodiment shown, the dead-latch function can be optionally canceled on only one side of the door; however, it can be used on both sides of the door.

5 also shows the function of the switch mechanism 36. In the position of FIG. 5, the face 86 of the switch 36, which rotates about the pivot pin 90, rests against the flap 88. By rotating the switch 36 around the pivot pin 90 in the arrow 92 direction, an additional face 94 of the switch 36 is applied to apply pressure of the flap 88 in the direction of the arrow 96 to the slide of the switch 98. This will slide the slide of the switch 98 in the direction of the arrow 96 and subsequently engage the latch 100 of the slide of the switch 98 into the respective notch 102 of the nut. Once the latch 100 has been engaged in the notch 102, the nut slider 19 cannot be rotated. In such a position, it is not possible to depress the crank 16 and thus no action can be taken with respect to the closing mechanism of the lock 10. This setting is common with the outside door handle. Conversely, after detaching the crank from the nut slider 19, i.e. after the latch 100 has been removed from the notch 102 (position in Figure 5), the crank 16 can be depressed to activate the lock mechanism K).

We now describe the operation of the latch 20 and the auxiliary latch 22 by means of the crank 16.

A part of the nut slider 19 is a cam 104 which is adjusted to press against the slider slider

106. The latch slider 106, which rotates around the pivot 108, includes a toothed arm 110 that fits with the teeth of the gear wheel 38 of the latch slider.

106 is preferably supported on the inner surface of the housing 12 by a spring 112. It can be seen from FIGS. 2, 3 and 5 that the tip 114 is mounted at the very end of the toothed arm 110. In the position of FIG. levers 60.

By rotating the crank 16 in the direction of the arrow 118 (Figure 4), the cam 104 pushes the latch slider 106 generally in the direction of the arrow 120. The tip 114 then rotates the gear lever 60 around the pivot 65 in the direction of the arrow 68 (Figure 3). generally in the direction of the arrow 68. As already mentioned, by engaging the tongue 58 of the gear lever 60 in the notch 56 of the support element 52, the movement of the support element 52 causes the latch 20 and the auxiliary latch 22 to slide into the unlocked position in FIG. it is possible to actuate the latch 20 and the auxiliary latch 22 by means of a crank 16.

Referring now to Figure 5, Figure 6 will be selected. The gear 38 can optionally be coupled to the pulse wheel 40 preferably by a tip 122. The tip 122 protrudes radially from a threaded fixture such as an adjusting screw 124. The adjusting screw 124 is screwed into the hub. 125, to which a pulse wheel 40 is fixedly mounted. In gear 38, there is an arcuate recess 126. In Figure 6, the tip 122 is in the recess 126. By corresponding rotation of the adjusting screw 124, the tip 122 can be ejected from the arcuate recess 126 (FIG. down). If the tip 122 is in the recess 126, by pressing the crank 16 in the direction of arrow 118, the cam 104 pushes the latch slide 106 generally in the direction of the arrow 120, causing the gear wheel 38 and the pulse wheel 40 to rotate in the arrow 50 direction. with the gear wheel 40. since the tip 122 abuts the recess 126 and thus connects the pulse wheel 40 with the gear wheel 38. As already mentioned, rotation of the pulse wheel 40 in the direction of the arrow 50 results in radial displacement of the spikes 46 into the radial grooves 44. the locking elements 24, 30, 32 and 34 are moved to the unlocked position in Figure 4. Thus, when the tip 122 is in the recess 126, by rotating the crank 16 in the direction of the arrow 118, the quick opening function occurs: the closing elements 24, 30, 32 and 34 as well as the latch 20 and the auxiliary latch 22 can thus be activated by partially rotating the crank 16 (usually, but not necessarily by an angle of approximately 30 °), and so on. o regardless of whether these elements have been locked or not.

If the tip 122 is not in the recess 126, the pulse wheel 40 is disengaged from the gear 38. In this case, turning the crank 16 in the direction of the arrow 118 does not activate the shut-off elements 24, 30, 32 and 34 but only the latch 20 and the auxiliary latches 22.

We will now describe how the dead latch 26 and the retaining lever 72 are canceled when selecting the quick-opening function by rotating the crank 16. The retaining lever 72 is preferably provided with a tongue 77 which contacts the nut slider 19 in position 5. Arrow 118 (Figure 4) exerts pressure on the tab 77 and causes the retention lever 72 to rotate about the pivot pin 76 in the direction of the arrow 63 and out of the Q position so that the tip 64 and the gear lever 60 are released. . Only after the dead-valve function has been released is the rotation of the nut slider 19 through the crank 16 to move the spike 114 relative to the inner cutout 116 so that the gear lever 60 can be rotated about the pivot 65 generally in the direction of the arrow 68 (Figure 3). This engages the latch 20 and the auxiliary latch 22 into the unlocked position in Figure 4.

As already mentioned, the key operated cylinder of the lock 14 may be installed on only one side of the door, or it may be in the form of a double cylinder installed from both sides of the door. Another alternative may be that the lock cylinders are installed from both sides of the door, allowing the key to be inserted into one of the lock cylinders on one side of the door and operating the latch 20 and the auxiliary latch 22, even with the key inserted and rotated in the lock cylinder. on the other side of the door. This feature, which is described herein with reference to Figures 7-14, may be advantageous in particular for locks installed in public places, such as hotels, where it may be necessary to enter the room in which the user left the key on the other side of the lock or even the lock from the other side locked.

Turning now to Figures 7-14, there is shown a pair of lock cylinders 200 that are embedded in opposite sides of the recessed lock 10 (the lock type of Figure 1, but shown for simplicity for simplicity) with design and functions in accordance with a preferred embodiment of the invention. A preferred part of both lock cylinders 200 is a tip drum 202 which is rotatably mounted in a bore 204. In the bore 204 between the end of the tip drum 202 and the cover 208 that is secured to the end of the lock cylinder 200, a gear clutch 206. the couplings 206 and the housing 208 are preferably interposed by two springs 210 that normally push the transmission clutch 206 to the end of the prong drum 202 into which the key is inserted. Center

The drum 202 and the transmission clutch 206 (Figure 8B) are designed such that the key 212 inserted into the tip drum 202 pushes the transmission clutch 206 against springs 210 and further, that the end of the transmission clutch 206 slides out of the lock cylinder 200

The end of the transmission clutch 206 is slipped from the lock cylinder 200 into the bore 214 of the connection throat 216. The connection throat 216 is secured to the pinion 42 (Figure 12-14) as described above. Upon insertion of the clutch 206 into the connection socket 216, by rotating the clutch 206 (due to the corresponding rotation of the key 212 inserted into the tip drum 202), the pinion 42 is rotated and the following mechanical functions of the lock 10 described above are performed. It can be seen from Figure 12 that the coupling opening 214 on one side of the pinion 42 is located asymmetrically with respect to the opening 214 on the opposite side of the pinion 42.

It can be seen from Figure 10 that the two connection sockets 216 are rotatably seated in the lock box 12 (one connection socket 216 is visible on the left side of the lock 10 in Figure 7). It can be seen from Figures 10 and 13 that a spring 218 is preferably disposed between the two connecting sleeves 216, which normally separates the two connecting sleeves 216 from each other. The two connection necks 216 are preferably seated on a common shaft 217 (Figure 13).

The function of the lock cylinder 200 will now be described. The key 212, when inserted into one of the lock cylinder 200, exerts a pressure on the transmission clutch 206 and pushes its end out of the lock cylinder 200 (see Figure 8B). At this stage (as seen from the lower cylinder 200 of the lock 200 in Figure 10, the key 212 being omitted for better clarity), the transmission clutch 206 will be inserted into the respective connecting hub 216. Then the key 212 can be rotated to rotate the connecting hub 216 and a pinion 42 and locking (or unlocking) of the lock 10. The second connecting throat 216 (located at the top in Figure 10) is pressed by a spring 218 against the transmission clutch 206 of the opposite cylinder of the lock 200 (at the top in the Figure 10). Because the clutch holes 214 are opposed asymmetrically, the upper coupling neck 216 will not be inserted into the transmission clutch 206.

Although the key 212 is inserted and rotated in the lower cylinder 200 (Figure 10), the second key 212 can be inserted into the upper cylinder 200 in Figure 10. As already mentioned, at this stage, the opening 214 of the upper connection neck 216 is not aligned however, the upper cylinder of the lock cylinder can be rotated with the key 212, so that the position of the upper transmission clutch 206 is correspondingly adjusted with the position of the opening 214 of the upper coupling neck 216.

······················································· · · ············································

At this point, the pressure 218 extends upwardly of the coupling neck 216 (in Figure 10) and the upper transmission clutch 206 is inserted into the opening 214. Once the upper coupling neck 216 is connected to the upper transmission clutch 206, the second key 212 can be rotated. both connecting ports 216 followed by pinion 42 rotation and unlocking (lock) of the lock 10 when the first key is inserted in the upper cylinder of the lock.

Those skilled in the art will appreciate that the present invention is not limited solely to what has been said and shown within this description. Included within the scope of the present invention are combinations, other sub-solutions of the features set forth herein, as well as modifications and variations thereof, which will be apparent to those skilled in the art upon reading this disclosure and are not part of the prior art.
