Description

Title: Security closure device for a door, a gate or the like

description

The invention relates to a security closure device for a door, a gate or the like and provided with such a safety closure device door, or gate, in particular garage door.

For example, in conventional garage door locks with one-sided or double-sided latch members, d. H. with two in operation in the opening and closing direction synchronously, but in opposite directions moving latch members, the actuation of the two locking members via a rotatable handle which is pivotable by a certain angle of rotation and a square shaft located in the lock mechanism double-armed pivot lever to the respective rotation angle swings. The pivot lever is provided at both ends in each case with a slotted slot, in which engages a fixed to the respective latch member link pin. Further, a spring-loaded in the closing direction locking element is present, which engages in the closed position of the locking members with a locking lug in a corresponding recess of the pivot lever and thereby blocks its rotation in the opening direction. By actuation by means of a key, however, this locking element can be moved against the spring tension from its locking position into a release position, after which then additionally has to be rotated via the handle of the pivot lever. As a result, the latch members are moved in their open position. Examples of such a door locking device can be found in DE 296 17 597 IM.

A closure for folding doors with opposite locking bars and an operable from a basic position operating lever reveals the DE 33 04 305 A1 wherein the operating lever can be blocked by a lock cylinder operable locking slide.

Such closure devices have the disadvantage that they are uncomfortable in their handling, since on the one hand, the actuation of a lock cylinder and then the operation of a handle is necessary. Furthermore, such constructions build very large, so that they can be used only very limited in doors and gates, in particular sectional doors.

The object of the invention is to provide a closure device which is very small, easy to handle and can be unlocked or locked by a simple operation of a lock cylinder, for example, to open a door, a gate or the like or safe close.

The object of the invention is achieved with the features of claim 1 and of claim 17.

The respective subclaims reflect a further embodiment of the inventive concept.

The safety closure device according to the invention is suitable for doors, for gates or the like. In this case, such a safety closure device with a to be actuated by a key from the outside and / or inside of the door, the door or the like profile cylinder or even from the inside by a handwheel in the form of a manual operation to open or close lock. Further manipulations are not necessary and thus represent a tremendous relief over the prior art. A profile cylinder has a single-speed design. Such a single-speed design always ensures that by a single turn of the key, a secure locking or rapid unlocking of the safety closure device is possible. To the profile cylinder in the region of its closing nose a gear has been mounted, which has a recess for the locking lug. Thus, the gear nestles around the locking nose around. This gear cooperates with a gear whose output gear acts on at least one displaceable, a toothing Verriege-Iungsstange. The at least one locking bar is blocked by a blocking device in the closed position. Thus, by merely pushing back the locking rod from the inside no opening of the door can be effected.

The transmission consists essentially of a plurality of gears, two of which are placed directly next to the profile cylinder so that they can interact with the gear, which is located around the locking lug around. Above the profile cylinder, another gear is available. On the axis of the additional gear is another gear, which cooperates with the toothing of the locking rod or the locking rods. In the normal state, the output gear is coupled to the rack and thus to the transmission via the common axis. Upon actuation of the lock cylinder by a key thus the rotational movement of the key is transmitted directly to the locking rod / n, which causes a large stroke of the locking rod / n due to the translation of the transmission.

The gears of the transmission preferably have an involute toothing.

In the excluded position of the locking bar, the blocking device engages in a recess of the locking bar. Should a controlled closing of the locking bar are effected, so the blockage must first be lifted. The blocking device is preferably formed by a spring element whose free end has a locking nose which engages in the recess within the locking rod. The spring element is designed so that it preferably has a pivoting in the region of the axis of the driven wheel and thus comes into contact with the axis or parts of the axle. Now, if the profile cylinder is actuated from the outside, it is first caused by a cam located on the axis, a lifting of the spring, which means a lifting of the blockage. Thereafter, the locking lug slides along the locking bar and only then falls back into a second recess, which has an inlet slope and outlet seh rage, into it; this is then the unlocked position.

In a manual operation of the inside of the door, the gate or the like, a coupling element must be actuated, namely, which disengages the gear from the output gear. Thus, it is possible by simple way that the manual operation is directly connected to the output gear whose teeth interact with the teeth of the locking bar. By a slight turn can thus be released from the inside, the lock or the door or the door are locked without actuation of the profile cylinder. The lifting of the blocking of the blocking device happens simultaneously with the rotation of the handwheel.

The profile cylinder can be designed as a half cylinder or as a double cylinder. In the embodiment as a double cylinder, of course, the security closure device can also be operated from the inside by a key.

The above-described parts or devices of the safety closure device are mounted on a hitch, so that This can be mounted directly in the door leaf or door leaf or on the door leaf or door leaf. From the outside of a circular recess is finished, in which a rosette is used for the profile cylinder. The rosette closes almost flush with the surface of the door, the gate or the like. The gear and in particular also the profile cylinder sit within a mounting block which is screwed to the hitch. On the mounting block are at the same time lateral guides for a guide of the locking rod / n. The mounting block is preferably connected by a plurality of screw with the hitch, but the screw are only accessible when a lock the door, the gate or the like has taken place. Such a construction allows only a removal of the screw from the inside of the door, the gate or the like. This is a security feature that expresses that manipulation of the safety closure device in the open state of the door, gate or the like on the mounting block or profile cylinder or the transmission is not possible.

In addition to the previously described embodiment with only one locking bar, it is understood that the safety locking device can also be designed with a second locking bar. The locking bars can be extended in particular by other elements, for example, if the safety closure device is not centrally but one-sidedly installed in the door, the gate or the like.

The locking state of the safety locking device can be connected, for example, by a sensor element in the form of a switch, which is connected within an electrical alarm circuit. Thus, it can also be determined by an indication whether the door, the gate or the like is locked or unlocked. The at least one locking bar is retracted when locking within a striking plate, which is located on the stationary area, ie on or in a frame of the door or the like. In order to prevent a levering of the gate, within the strike plate is an opening, which is dimensioned so that the locking rod can penetrate with a straight approach. The approach is there that a levering of the door, the gate or the like can not take place.

The present description shows that with the invention, a safety closure device has been created, which has been built very compact and very compact. In addition, a modularity is that the same structure can be used even if, for example, the manual locking is omitted from the inside. Likewise, a very large stroke of the locking rod is possible by the design of the transmission even with a single-movement movement of the locking lug, which always provides the security that is given by the one-time rotation of the key a secure locking. In a multi-speed closure device this is not given.

In addition, the present safety closure device also provides a secure burglary protection, which not only prevents a levering of the door, the gate or the like but also makes an unauthorized removal of the profile cylinder impossible, since the attachment of its rosette is performed from the inside over the mounting block.

The invention will be explained in more detail below with reference to two possible schematically illustrated embodiments in the drawings.

Fig. 12 is an illustration of a second embodiment of a transmission with profile cylinder. In the following description, all non-essential to the invention parts have been omitted, in particular a door, a gate or the like and a comprehensive frame.

In the figure 1, a closure device 1 is shown in a perspective view. To the right of the closure device 1 is a strike plate 2 with an opening 18, wherein the strike plate 2 is connected via an adjustable screw 11 with a fastening 3. The attachment 3 is attached to a frame or masonry, not shown, of a building.

The closure device 1 is shown on a mounting device 5, which is fastened by means of fastening screws 15 in or on a door, a gate or the like. In this case, a profile cylinder 12 by means of a rosette 4, which is embedded in the / the door, gate or the like, not shown, accessible from outside. In this embodiment, it is a half cylinder, which can of course also be designed as a double cylinder.

On the inside of the door, the gate or the like, a manual operation 10 is provided to open from inside the door, the gate or the like without actuation of the profile cylinder 12 or lock. The function of the manual operation will be described below.

As shown in FIG. 1, two locking rods 6 and 7, which can be actuated in opposite directions, are provided in the closure device 1. It should be noted that the closure device 1 can also be equipped with only one locking bar 6. For larger opening widths of gates or the like, the locking rods 6,7 can be extended accordingly at their ends. The locking rods 6,7 are located laterally on the hitch 5 Side parts 23 are each guided within a passage 14. The side parts 23 are relative to the hitch 5 adjustable.

To query the position of the locking rods 6,7 a sensor 13 is provided which can be electrically connected to a display or alarm system or the like.

FIG. 2 shows, contrary to FIG. 1, the locking bars 6 and 7 in their locking position. In this case, a free end of the locking rod 6 engages in the striking plate 2. To prevent a levering or pushing out in the locked position, located at the end of the locking rod 6, for example, a locking element 19 in the form of a projection.

In this locking position also engages a locking lug 21 of a blocking device 20 in a recess 17, which is located as a recess in the locking rod 6, a. The blocking device 20 ensures that unintentional or intentional insertion of the locking rods 6, 7 into the closure device 1 makes it impossible to open the door. This is omitted by the fact that the locking lug 21 is embedded in the angularly executed recess 17.

By moving the locking rod 6, a switching spring 22 of a sensor element 13 is also free, indicating that the locking rod 6 is in its locking position or not.

The same position of the closure device 1 is shown in a plan view of FIG. The blocking device 20 with its end, namely the locking lug 21, lies in the recess 17. In the unlocked position, the locking lug 21 would be in one with a run-on slope provided recess with stop 37 within the locking rod 6 come into engagement.

The profile cylinder 12 penetrates a mounting block 26, the fastening 27 is accessible only in the locked state via a recess 25 which is located within the locking bar 6. The profile cylinder 12 is mounted within the mounting block 26 via a conventional screw 43 (Figure 4). These screw 43 is accessible only from the inside of the door, the gate or the like. To guide the locking rods 6 and 7 26 guides 16 are present on the mounting block.

An embodiment of the closure device 1 according to the invention, in an unlocked position with only one locking bar 6, is reproduced in FIG.

In order to better reproduce the operational behavior of the closure device 1, a part of the parts described above is omitted in the following figures.

In FIG. 5, neither of the two locking rods 6 and 7 is present any more, and the handwheel of the manual override 10 has also been removed. FIG. 5 makes it very clear that this is a very compact component of the closure device 1, wherein a transmission is used in particular for the operational transmission of the displacement movement of the locking rods 6 and 7.

A first embodiment of a transmission is made clear, in particular, by FIG. 6, in which, with respect to FIG. 5, the mounting block 26 has been removed. To the profile cylinder 12 with its locking lug 33 sets a gear 31 which has no teeth in the region of the locking lug 33. However, with this toothed wheel 31 there are further toothed wheels, namely the teeth wheels 28 and 30 directly and indirectly the gear 29, in geared connection. This is particularly apparent from Figure 7, in which the profile cylinder 12 is in its initial position. Now, if the profile cylinder 12 is rotated, as it is expressed in the figure 8, for example, by about 130 °, the closing nose 33 comes at some point in the pitch circle of the gear 28, which would result in a blockade. To avoid this, located in the gear 28, a tooth portion 35 which is designed so that the locking lug 33 on its circular path can pass through this portion of the gear 28 without problems. At the same time, however, the gear 28 with the gear 29 remains in engagement, whereas the gear 29 with the gear 30 and this with the gear 31 is also engaged. Also, the gear 30 has a recessed tooth portion 35, which cooperates with an advanced tooth portion 36 of the gear 29. Due to the close arrangement of the gears 31, 28, 29 and 30 it is clear that always by turning the profile cylinder 12, the gears 28, 29, 30, 31 all remain engaged with each other. This also shows the figure 9, in which the locking nose 33 has been rotated by 180 ° relative to the starting position.

FIG. 10 once again shows the operational connection between the toothed wheels 31, 28, 29 and 30, whereby at the same time, however, the blocking device 20 has also been drawn. By the rotation of the profile cylinder 12, the blocking device 20 is represented by a cam, not shown, which is located in the axis region of the gear 29 and a driven gear 41, right at the beginning of the rotational movement. For better clarification of the operational relationships of the gears 31, 28, 29 and 30, reference is also made to FIG.

Upon actuation of the closure device 1 via the manual override 10, a clutch is activated, which performs a decoupling of the transmission of the output gear 41. This is on the axis of the Output gear 41 adjacent to the cam, not shown, for the operation of the blocking device 20 preferably at the end of a coupling pin 28 is present. By pushing the handwheel into the closure device 1 is due to a spring 32 of the coupling pin 38 is pushed through a link 39 which is located in the gear 29, and thus virtually achieved a freewheeling gear, but at the same time with the rotational movement of the manual operation 10th a translational movement of the locking bars or 6 and 7 are effected. If the manual override 10 is released again, then, due to the spring force of the spring 32, coupling of the transmission to the output gear 41 via the coupling pin 38 is automatically performed again.

Figure 12 shows a second embodiment of a transmission of the type described above. The transmission of the first embodiment was very flat in height, with the transmission of the second embodiment being constructed very narrow in width. Here, the gears 28,30 are greater in height than in diameter and have a portion 42 which allows the locking lug 33 through the range of the gears 28, 30 to rotate through the entire geared connection of the

Gears 31, 28, 29, 30 is maintained. Otherwise, the structure of the

Closing device performed similar.

The entire safety closure device 1 can be concealed with a corresponding thickness of the door leaf, the door leaf or the like, but also an execution of the safety

Closing device can be mounted directly on the door leaf, the door leaf or the like. In such a case, the

Closing device 1 is provided with a separate housing. Thus, depending on the application, a narrow or a higher

Embodiment of the two transmission variants are selected. At this

Contemplation, the invention also includes all equivalents and variants one. It is also possible to automate such a closure device 1 by a corresponding device, for example with radio and an electric motor drive unit. Such an electromotive drive unit can, for example, directly or indirectly engage the transmission or be connected via an automated coupling with the locking bar or n 6,7. In such an automation, of course, the above-described functions, namely the operation via a key from the outside and optionally from the inside and the manual operation from the inside remain.
