Description

The present invention relates to a bolt lock for securing a wing of a door, a window or the like, with at least one pivot bolt pivotable about a pivot axis between a locking position blocking the wing and a unlocking position releasing the wing.

Such a bolt lock is known in principle and is used, for example, to lock a door or a window against a break-in, e.g. Protect against unauthorized opening of the door or window by an unauthorized person. For this purpose, the bolt lock is usually attached to a stationary component, such as a frame, the door or the window, whereby by pivoting the pivot bolt in its securing position, a movable component, for example a wing, the door or the window is blocked that the door or window can no longer be opened or at least not significantly. So that an authorized person can still open the door or the window, the swivel bolt can be swiveled from the safety position into a release position, in which the swivel bolt no longer blocks the sash of the door or window, i.e. releases, and the wing of the door or window can be moved past the swivel latch.

Known bolt locks have a blocking means which, in its locked position, blocks the swivel bolt against unintentional pivoting back from the securing position into the unlocking position. At the same time, it should also be possible for an authorized person to release the blocking of the swivel bolt if necessary by moving the blocking means from its locked position to a release position. Usually, the blocking means is shifted from the blocking position into the release position by rotating a core which is rotatably mounted in a locking cylinder about an axis of rotation with the aid of a key.

In the prior art, the direction of displacement of the blocking means and / or the axis of rotation of the lock cylinder core are oriented perpendicular to the pivot axis of the pivot bolt, so that a complex deflection mechanism is required to displace the blocking means, which is often associated with a space-consuming construction of the bolt lock.

It is therefore an object of the invention to provide a more compact bolt lock.

The object is achieved by a bolt lock with the features of claim 1.

The bolt lock according to the invention comprises a swivel bolt, a blocking means and a locking cylinder coupled to the blocking means. The pivot bolt can be pivoted about a pivot axis between a locking position blocking the wing and a unlocking position releasing the wing, and the blocking means can be displaced at least approximately parallel to the pivot axis of the pivot bolt between a release position releasing the pivot bolt and a blocking position blocking the pivot bolt against its pivoting. The locking cylinder also has a core which can be rotated about an axis of rotation oriented at least approximately parallel to the pivot axis of the pivot bolt between an unlocking position and a locking position.

The invention is based on the general idea that a complex deflection mechanism can be dispensed with if the pivot axis of the pivot bolt, the direction of displacement of the blocking means and the axis of rotation of the core of the locking cylinder are aligned at least approximately parallel to one another. Since the deadbolt lock does not require a complex deflection mechanism, there is the advantage that the deadbolt lock can be made more compact, which, in addition to cost-effective production, also improves the overall appearance of the deadbolt lock attached to a frame of a door or window.

Advantageous embodiments of the invention can be found in the subclaims, the description and the drawings.

The bolt lock can have a spring means which acts on the blocking means in the direction of its blocking position, so that the blocking means is held securely in its blocking position and the pivot bolt is reliably blocked in its securing position. In particular, the spring means serves to shift the blocking means from the release position into the blocking position when the core of the locking cylinder is in the locking position and the swivel bolt is pivoted out of the unlocking position into the locking position. In other words, the blocking means in the release position is biased by the spring means in the locking position of the lock cylinder core and in the unlocking position of the pivot bolt, so that when the pivot bolt is pivoted into the securing position, the blocking means automatically engages in the blocking position and the pivot bolt located in the securing position blocked.

At this point, it should be noted that the locking cylinder can be designed such that a key provided for rotating the core of the locking cylinder can only be removed in the locked position of the core.

So that the swivel bolt is not already blocked by the blocking means in the unlocking position, the blocking means preferably has a collar section which, in the release position of the blocking means, is supported on a portion of an end face of the swivel bolt located in the unlocking position that is at least approximately perpendicular to the swivel axis. In other words, the swivel bolt located in the unlocked position prevents the blocking means from being able to be shifted from the release position into the blocking position.

To secure the pivot bolt in its unlocking position against unintentional pivoting into the locking position, the collar section can have a latching projection which engages in a latching groove provided on the pivot bolt in the unlocking position of the pivot bolt. However, it is also conceivable that the collar section has a locking groove for the same purpose and the swivel bar has a locking projection.

If the swivel bolt is pivoted from the unlocking position into the securing position, the end face of the swivel bolt slides past the collar section and the blocking means is displaced from the release position into the blocking position due to the spring force of the spring means. The blocking means in the blocking position prevents the swivel bolt from being pivoted back into the unlocking position from the securing position.

For a particularly reliable blocking of the pivot bolt in its securing position, a section of a longitudinal side surface of the pivot bolt oriented at least approximately perpendicularly to the end face section can be supported on an outer surface of the collar section of the blocking means in the blocking position in the securing position of the pivot bolt.

So that the blocking means located in the blocking position can be shifted from the blocking position into the release position when necessary, the bolt lock advantageously comprises a driver for shifting the blocking means from the blocking position into the release position.

The driver together with the blocking means can form a ramp mechanism which serves to move the blocking means against the spring force of the spring means out of the blocking position of the blocking means into its release position. The ramp mechanism preferably has a ramp formed on the driver, which cooperates with an extension formed on the blocking means. However, the ramp can also be formed on the blocking means and the extension can be designed in a corresponding manner on the driver.

A particularly compact design of the bolt lock can be achieved if the driver is at least partially supported in the blocking means.

According to an advantageous embodiment of the bolt lock, the driver can be rotated about an axis of rotation and the ramp surrounds the axis of rotation at least in sections in a spiral manner. In particular, the driver can be coupled to the rotatable core of the locking cylinder, wherein a rotation of the core of the locking cylinder from the locking position into the unlocking position preferably causes the blocking means to be shifted from the locking position into its release position. If the driver is rotatable, it is advantageous if the driver is rotatably mounted at least in sections in the blocking means.

The ramp mechanism preferably comprises two ramps which surround the axis of rotation of the slave in a double spiral. A guide extension can be assigned to each of the two ramps.

For a compact construction of the bolt lock, it is also advantageous if the axis of rotation of the core of the lock cylinder and / or the axis of rotation of the driver and / or an at least approximately parallel to the direction of displacement of the blocking means and centrally through the blocking means center axis are coaxially aligned with each other.

To protect against contamination, but also to increase the security of the bolt lock, a housing for mounting the pivot bolt can be provided, which receives the pivot bolt in the direction of its pivot axis between a front housing section and a rear housing section. The front housing section and the rear housing section are preferably connected to one another by means of a connecting section, in particular by means of a connecting section which is oriented at least approximately parallel to the pivot axis of the pivot bolt.

If the bolt lock has only one swivel bolt, the front housing section, the rear housing section and the Connection section can be arranged such that the housing is U-shaped in longitudinal section.

To further increase security, but also to use the bolt lock for a double door, a double window or the like, the bolt lock can also have two pivot bolts, the pivot axes of which are aligned at least approximately parallel to one another and which are arranged on opposite sides of the blocking means. In such a configuration of the bolt lock, the front housing section, the rear housing section and the connecting section can be connected to one another in such a way that the housing is H-shaped in longitudinal section.

So that the bolt lock can be attached to a frame of a door, a window or the like in a space-saving manner, a longitudinal extension of the housing is preferably aligned at least approximately at right angles to the pivot axis of the at least one pivot bolt. A wing of the door, the window or the like can then be guided past the bolt lock unhindered when a longitudinal extension of the pivot bolt in the unlocking position is oriented at least approximately parallel to the longitudinal extension of the housing. In contrast, the deadbolt lock prevents an unintentional opening of the leaf if the longitudinal extension of the pivot bolt in the securing position is advantageously oriented transversely, in particular at least approximately at right angles to the longitudinal extension of the housing.

The pivot bolt can have a base plate for rotatable mounting of the pivot bolt, in particular on the housing of the bolt lock. In addition, the swivel bolt preferably comprises a swivel bolt bracket which is bent in a U-shape around the swivel axis of the swivel bolt.

According to an advantageous embodiment of the bolt lock, the base plate and the swivel bolt bracket are formed in one piece. However, the base plate and the swivel bolt bracket can also be separate components which are connected to one another in a positive and / or non-positive manner. This makes it possible to manufacture the swivel bolt bracket from a harder material, such as tempering steel, and the base plate from a softer material, such as a flat sheet. Such a construction of the pivot bolt enables the bolt lock to be manufactured particularly cost-effectively.

If the swivel bolt bracket is made of a harder material and bent in a U-shape, the legs of the swivel bolt located in the secured position serve to absorb forces occurring during an attempted break-in in the direction parallel to the swivel axis. At the same time, the base plate prevents the swivel bolt from being knocked out of the housing, for example by means of a striking tool, perpendicular to the swivel axis.

The key is preferably designed as a mechanical key. However, it is also conceivable that the key is an electronic key, so that the core of the lock cylinder can be rotated if a coding signal of the key matches a reference code stored in the bolt lock. It goes without saying that an electromotive drive can be provided for rotating the lock cylinder core.

Although the invention is described in connection with a door or a window, it goes without saying that the bolt lock according to the invention can also be used for other purposes, such as for securing a gate or a cat flap.

1 to 3rd show a bolt lock for securing a wing, not shown, of a door or a window. That in the 1 to 3rd The bolt lock shown comprises two swivel bolts 10a , 10b which in a housing 12th each about a swivel axis S are pivotally mounted between a locking position blocking the wing and a unlocking position releasing the wing. Every swivel bolt 10a , 10b includes one Swivel lock bracket 11a and a swivel bolt cover 11 b. Each swivel bolt bracket 11a is about the swivel axis S of the respective pivot bolt 10a , 10b Bent in a U-shape and has two legs 13 ( 1 and 6 ).

For storing the swivel bolts 10a , 10b each have a base plate 58 on which with the respective swivel bolt bracket 11a is positively and / or non-positively engaged. For this purpose, the swivel bolt bracket includes 11a in the area of the swivel axis S a milled out 60 as well as on each leg 13 in one to the swivel axis S spaced outer area each have a recess 62 . The base plate 58 on the other hand has one for milling 60 complementary coupling section 66 as well as the recesses 62 complementary tabs 64 on.

The coupling section is in the assembled state of the bolt lock 66 positive and / or non-positive in the cutout 60 of the swivel bolt bracket 11a and the ledges 64 each in the corresponding recesses 62 of the swivel bolt bracket 11a added. That being said, the base plate 58 in the assembled state of the bolt lock essentially between the two legs 13 of the swivel bolt bracket 11a arranged.

The housing 12th includes a front housing section 14 and a rear housing section 16 which by means of a connecting section 18th are interconnected and which are on opposite sides of the housing 12th one hook each 10a , 10b in the direction of its pivot axis S record between them. The housing 12th also includes a cover 20th which the front housing section 14 covers.

As especially with the help of the in 3rd Side view of the bolt lock shown can be seen, are the front housing section 14 , the rear housing section 16 and the connecting section 18th interconnected such that the housing 12th is H-shaped in the longitudinal profile or in the longitudinal section. In contrast, the deadbolt lock should only have a swing bolt 10th have, so the individual sections of the housing 12th also be arranged such that the housing 12th is U-shaped in longitudinal section.

Based on 2nd and 3rd can be seen that a longitudinal extension of the housing 12th at least approximately at right angles to the respective pivot axis S the swivel bolt 10a , 10b is aligned. Also show 2nd and 3rd a swivel bolt in the unlocked position 10a (upper hook) 10a) , which is at least approximately parallel to the longitudinal extent of the housing 12th is aligned, and a swivel bolt located in the secured position 10b (lower hook) 10b) , which is at least approximately perpendicular to the longitudinal extent of the housing 12th is aligned. It is understood that the pivot bolt is in the secured position 10b with a corresponding design of the door or the window could also be pivoted through 180 ° in the opposite direction.

To fasten the bolt lock to a frame of the door or window, not shown, are two fastening means 22 provided which the front housing section 14 and the rear housing section 16 of the housing 12th penetrate and around which the swivel bolts 10a , 10b are each pivotable ( 1 to 3rd ). In other words, define the respective longitudinal extensions of the fastening means 22 the swivel axes S the swivel bolts assigned to them 10a , 10b .

The fasteners 22 are preferably each in the form of a thread-forming screw. Furthermore, for each fastener 22 a fan anchor to hold the fastener 22 be provided in a cavity.

In order to adjust a height difference between the frame and the sash for an optimal fastening of the deadbolt lock to the door or the window, there are different spacer elements of different thicknesses 24th provided which between the rear housing section 16 of the housing 12th and the frame can be arranged.

To block the swivel bolts located in the safety positions 10a , 10b the bolt lock also has a blocking means 26 . The blocking agent 26 is between the swivel bolts 10a , 10b against its pivoting blocking position and one of the swivel bolts 10a , 10b releasing release position at least approximately parallel to the pivot axes S the swivel bolt 10a , 10b relocatable.

So that the blocking agent 26 the swivel bolts 10a , 10b always blocked in their safety positions is a spring means 28 provided which the blocking agent 26 acted towards its locking position. The spring means 28 is formed in the illustrated embodiment in the form of two helical compression springs, each with one end in the front housing section 14 stored and with its other end in each case on a collar section 30th of the blocking agent 26 trained bag 32 are included.

How especially based on 1 and 4th can be seen, shows the blocking agent 26 a collar section on opposite sides 30th on. The collar sections 30th not only serve to hold one end of the helical compression springs, but also prevent the blocking agent 26 the swivel bolts 10a , 10b already blocked in their unlocking positions. Each section of the collar is supported for this 30th of the blocking agent in the release position 26 on an at least approximately perpendicular to the respective pivot axis S of the corresponding swivel lock 10a , 10b aligned portion of an end face 34 the swivel bolt located in the unlocked position 10a , 10b from.

On one to the bag 32 opposite side of a respective collar section 30th or on a corresponding swivel bolt 10a , 10b each collar section has a facing side 30th a locking tab 35 ( 4th ) on which in the unlocked position of the swivel bolt 10a , 10b into one on the swivel latch 10a , 10b provided locking groove 37 ( 2nd and 3rd ) engages and an unintentional swiveling of the swivel lock 10a , 10b prevented in the securing position.

Become the swing bolts 10a , 10b pivoted from their unlocking positions into their securing position, the respective end faces slide 34 the swivel bolt 10a , 10b on the collar sections 30th over and the blocking agent 26 is determined by the spring force of the spring means 28 shifted from the release position to the locked position.

In the blocking position of the blocking agent 26 is supported in each case approximately perpendicular to the end face section 34 aligned portion of a long side surface 36 of the respective pivot bolt 10a , 10b on an outside surface 38 the collar sections 30th of the blocking agent in the blocking position 26 from.

For shifting the blocking agent 26 from its locked position to its release position is a driver 40 provided which together with the blocking agent 26 forms a ramp mechanism. The blocking agent 26 against the spring force of the spring means 28 shifted.

The driver 40 is in one pass at least in sections 41 of the blocking agent 26 about an axis of rotation There rotatably mounted. In addition, the driver 40 with one between an unlocked position and a locked position about an axis of rotation Db twistable core 42 a locking cylinder 44 coupled. For this, the driver points out 40 one to the core 42 facing jetty 46 on which one with the core 42 provided slot 48 is positively and / or non-positively engaged. The twist of the core 42 is done using a suitable key 50 .

If the core is twisted 42 from the locked position to the unlocked position becomes the one with the core 42 coupled driver 40 also twisted. Two run in the passage 41 of the blocking agent 26 trained and at least approximately parallel to the central axis M of the blocking agent 26 aligned extensions 52 each on one on the driver 40 trained ramp 54 on and the blocking agent 26 is from the locked position against the spring force of the spring means 28 shifted to the release position. The two on the driver 40 trained ramps 54 for the extensions 52 of the blocking agent 26 surround the axis of rotation There of the driver 40 double spiral. Each of the ramps 54 each has two stops 56 on what a rotational movement of the driver 40 limit.

The shifting of the blocking agent 26 from the locked position to the release position takes place against the spring force of the spring means 28 , causing the blocking agent 26 is biased to a certain extent. When the swivel bolts are swiveled 10th , 10a , 10b in their respective securing positions causes the spring force of the spring means 28 that the blocking agent 26 is automatically shifted from the release position to the locked position, especially if the core 42 of the locking cylinder 44 is in the locked position. Take the swivel bolts 10th , 10a , 10b their locking positions, so the swivel bolts are supported 10th , 10a , 10b each other through the blocking agent 26 from which a particularly high level of security against burglary of the bolt lock can be achieved.

How especially based on 1 can be seen are the axis of rotation Db of the core 42 of the locking cylinder 44 , the axis of rotation There of the driver 40 and an at least approximately parallel to the direction of displacement of the blocking means 26 aligned and centered by the blocking agent 26 extending central axis M aligned coaxially to each other. Moreover, the axis of rotation Db of the core 42 , the axis of rotation There of the driver 40 and the central axis M of the blocking agent 26 to the respective swivel axes S the swivel bolt 10a , 10b aligned at least approximately parallel, which on opposite sides of the blocking agent 26 run.
