Description

DESCRIPTION

profiled lock cylinder

The invention relates to a profiled locking cylinder with at least one rotating core in a housing, with a locking bit that can be actuated by the core, with a drive device for coupling the closing bit with the movement of the core and with a guide device for guiding the closing bit, the closing bit being guided by the guiding device in a direction deviating from the rotational movement of the core.

Such profile lock cylinders have a locking mechanism which may be a key inserted into the core or one electronically controlled to selectively lock or release movement of the core relative to the housing. Furthermore, said profiled locking cylinders are provided with a knob with which the core can be turned after release. The profiled lock cylinder is a standardized component that can be used in various door or gate locks.

From WO 98/23828 A1, a profile cylinder lock is known in which a bolt part is arranged linearly and displaceably in a cylinder lock housing. The bolt part has a hole in its longitudinal extension to receive a drive pin arranged in a lock axis eccentrically to the axis. This allows the lock axis to pivot only in a narrowly limited angular range, therefore the control possibilities of the locking mechanisms are limited.

DE 11 72 141 B discloses a cylinder lock in which a locking bolt projecting transversely to the axis of a cylinder lock housing can be actuated by a rotary cylinder. The locking bolt has an elongated recess in its lateral surface to receive a control pin. Therefore, the rotary cylinder can only pivot in a limited angular range, so the control possibilities of the closing mechanisms are limited.

EP 3 620 597 A1 discloses a lock cylinder in which a lock flange has a guide means on each of two opposite faces. Next to one of the guide means there is a hooking recess for a coupling element.

A profiled lock cylinder is known, for example from DE 10 2008 056 627 C5. In this profiled lock cylinder, the lock bit is rotatably mounted and rotatably connected to a designed handle, for example in the form of a knob. A control element is connected to the closing bit by means of a lifting movement through a toothed gear.

A disadvantage of the known profiled locking cylinders is that the locking bit is rotatable together with the core, whereby the control possibilities of the locking mechanisms are very limited. Furthermore, the twistlock bit requires a recess in the housing, which leads to its weakening.

The invention is based on the problem of further optimizing a profiled closing cylinder of the type mentioned at the beginning in such a way that it offers a plurality of possibilities for controlling the closing mechanisms.

According to the invention, this problem is solved in such a way that the driving device has a rotatable cam with the core in a recess of the closing bit, and that the recess is arranged on a front face of the closing bit, and the guide is arranged on the other side in the center of the closing bit.

By means of this design, the movement of the closing bit can be easily adapted to the requirements of the closing mechanism to be actuated. Since the locking bit itself executes the intended direction of movement, the lock containing the locking mechanism can have the known standard receptacle for the profiled locking cylinder. Thanks to the invention, a large number of closing mechanisms can be controlled with the profiled closing cylinder. If the closing bit does not have to be guided below the core, the casing can also be guided up to the height of the core in the region of the closing bit and thus have a particularly high stability. The transmission of the rotational movement of the core to a movement of the closing bit that deviates from it is particularly simple, since the driving device has a cam that can rotate with the core in a gap in the closing bit. In the simplest case, the cam is an eccentric. The profiled lock cylinder is designed to be particularly simple in that the recess is provided on one front face of the lock bit and the guide is provided on the other face in the center of the lock bit.

According to another advantageous optimization of the invention, the transmission of the force from the core to the closing bit is particularly simple if the guide device has a guide for the closing bit arranged transversely to the axis of rotation of the core and if the driving device is designed to transmit the rotational movement of the core to the movement of the closing bit along the guide.

The locking bit could, for example, be mounted as a pivot bolt. However, the profile lock cylinder has a very high stability even with a small installation space if the guide is designed to guide the lock bit straight.

A first rotational movement can often be transmitted to the core without completely unlocking the profiled lock cylinder. According to a further advantageous embodiment of the invention, a transfer of an initial rotational movement of the core to a movement of the closing bit can be easily avoided if the cam has a triangular or quadrangular cross-section. By this design it can be ensured that no movement is initiated in the cam until the core has rotated 45° or 60°. This contributes to a strong increase in the security of the profiled lock cylinder against unauthorized unlocking.

The play of the closing bit in the case of a triangular cam can be easily avoided according to a further advantageous optimization of the invention, if the cam is formed as a Reuleaux triangle. A Reuleaux triangle is made up of several circular arcs and has the property of having the same diameter at each point. In this way, the cam fills the gap in the closing bit in any rotation position.

According to a further advantageous optimization of the invention, the mounting of the profiled closing cylinder is particularly simple if the recess in the closing bit for the cam is open on one side and if the guide of the guide device is arranged transversely to the opening of the recess.

According to another advantageous optimization of the invention, the guide device is highly stable if the guide device has a closing bit guide that is held positively in the housing and because the closing bit guide and the closing bit itself have a groove. guide and a guide core corresponding to each other.

According to another advantageous optimization of the invention, the direction of movement of the closing bit can be easily adjusted if the closing bit guide has a rotating cylindrical segment in the housing and a clamping bolt for locking the closing bit guide in a designated position. on the casing. Preferably, the casing or the cylindrical segment of the lock bit guide has a series of holes into which the clamping bolt enters after assembly.

According to a further advantageous optimization of the invention, it helps to simplify the adjustability of the closing bit's direction of movement if the clamping bolt is shaped as a resilient locking bolt.

In order to increase the stability of the profile lock cylinder according to another advantageous optimization of the invention, it helps to increase the stability of the profile lock cylinder if the lock bit guide is screwed to a protruding casing web from a bearing application of the shell for the core. Said casing core usually has a hole for screwing the profiled locking cylinder into a lock. In double profile lock cylinders with two cores, the web connects the halves of the profile lock cylinder. Since the closing bit does not rotate with the core, the web can have a large cross-section and be guided into the core in the area of the screw hole.

The invention allows numerous possible manufacturing models. To clarify their basic principle, two of them are shown in the drawing and described below. This drawing shows in the:

FIG. 1 a perspective view of a first production model of a profiled lock cylinder according to the invention,

figure 2, an exploded view of the profiled lock cylinder of figure 1, and an exploded view,

FIG. 3 a sectional view through a drive device from FIG. 1 along line III-III, FIG. 4 a sectional view through a guide device from FIG. 1 along line IV-IV, figure 5, a perspective view of a second production model of a profiled lock cylinder according to the invention,

figure 6, an exploded view of the profiled lock cylinder of figure 5,

FIG. 7 a sectional view through a drive device from FIG. 5 along the line VII-VII, FIG. 8 a sectional view through a guide device from FIG. 5 along line VIII-VIII.

Figure 1 shows a profiled lock cylinder with a rotating core 2 in a casing 1 and with a locking bit 3 that can engage with the core 2. The casing 1 has a web 4 that is guided from one side to a second side. of the housing and has a screw hole 5 into which the profile cylinder can be screwed into a lock not shown. In the web 4 there is a hole 6 below the closing bit 3. Between the core 2 and the closing bit 3, a drive device 7 is arranged to transmit an actuating force from the core 2 to the closing bit 3. On the opposite side of the actuating device 7, a driving device is arranged. guide 8 to guide the closing bit 3 in a direction deviating from the rotational movement of the core 2. A guide part 9 of a closing bit guide 10 of the guiding device 8 is fixed in the recess 6.

Figure 2 shows the profiled lock cylinder of Figure 1 in an exploded view. Here it can be seen that a plug 11 is arranged in the casing 1 opposite the core 2. In the plug 11, for example, a battery can be arranged, not shown, for an electronic locking mechanism, also not shown, for selectively block or release the movement of core 2. For example, a knob, not shown, may be attached to core 2.

The profiled lock cylinder shown is a single-sided profiled lock cylinder. Of course, a double profiled lock cylinder, not shown, can also be designed with two drive devices 7 and a guide device 8 arranged centrally on the lock bit, as described in Figures 1 to 4.

Fig. 3 shows a sectional view through the profiled lock cylinder from Fig. 1 along the line III-III through the drive device 7. The coupling device 7 has a cam 12 that can be connected in a positive way. rotatably fixed to the core 2 which is guided in a hollow 13 opened in one face of the closing bit 3. The cam 12 has an essentially triangular shape and is formed as a Reuleaux triangle. The cam 12 thus completely fills the height of the recess 13 in any rotational position. The recess 13 has an opening 14 which is arranged transversely to the guide piece 9 for the closing bit 3.

Figure 4 shows a sectional view through the profiled lock cylinder of Figure 1 in a sectional view along the line IV-IV through the guide device 8. Here it can be seen that the lock bit 3 has a guide web 15 which is guided in a straight line by the closing bit guide 10 with the guide part 9 in the drawing plane along a guide groove 16. In this way, the guide device 8 It has a guide for the closing bit 3 arranged transversely to the axis of rotation of the core 2.

As the core 2 rotates, the cam 12 shown in Figure 3 rotates and the lock bit 3 moves up and down, thus deviating from the rotational movement of the core 2. The lock bit 3 projects upwards, away of the web 4 of the casing 1. In an alternative production model not shown, the closing bit 3 can also be angled outside the casing 1 in the form of a hook or project transversely from the casing 1. In this way, the locking cylinder Profile lock can easily be adapted to the intended locking mechanism of a lock by using a correspondingly designed locking bit 3 .

FIG. 5 shows another production model of a profiled lock cylinder, in which a rotating core 102 in a housing 101 has a lock channel 117 for inserting a key. The core 102 is coupled to the closure bit 103 through a drive device 107 as in the manufacturing model. The closure bit 103 is connected to the casing 101 through a guide device 108 for guiding in a direction other than the direction of rotation.

Figure 6 shows the profiled lock cylinder of Figure 5 in an exploded view. Here it can be seen that the guide device 108 has a guide arranged transversely to the axis of rotation of the core 102 with a guide groove 116 arranged in a closing bit guide 110. The closing bit guide 110 has a rotating cylindrical segment 118 in the housing 101 and a clamping bolt 119 for locking the locking bit guide 110 in a rotational position provided in the housing 101. The clamping bolt 119 is guided axially in the housing 101 and is biased by a spring element 120 within a plurality of recesses 121 in the closing bit guide 110.

Figure 7 shows the drive device 107 of the profiled closure cylinder of Figure 5 in a sectional view along the line VII-VII. The drive device 107 is constructed as described in figure 3 and has a cam 112 arranged in a recess 113 of the closing bit 103.

Figure 8 shows the guide device 108 of Figure 5 in a sectional view along line VIII-VIII. Here it can be seen that the closing bit guide 103 has a guide web 115 arranged in the closing bit 103 which is arranged in a guide groove 116 of the closing bit guide 110. Thus, by selection of a corresponding rotational position of the closing bit guide 110 in the housing 101, the position of the closing bit 103 can be adjusted by means of the clamping bolt 119. In addition, the closing bit 103 can be projected transversely and moved upwards and down.
