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 be for an authorized person will still be able 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 pivot 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 which is at least approximately perpendicular to the end face section can be oriented in the securing position of the pivot bolt support a longitudinal side surface of the pivot bolt on an outer surface of the collar portion of the blocking means located in the blocking position.

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 connecting section can be arranged in such a way 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 at least approximately parallel to one another and which are arranged on opposite sides of the blocking means. With 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 such 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 3 show a bolt lock for securing a wing, not shown, of a door or a window. That in the 1 to 3 The bolt lock shown specifically comprises two swivel bolts 10a, 10b, which are each pivotably mounted in a housing 12 about a swivel axis S between a locking position blocking the wing and a unlocking position releasing the wing. Each swivel bolt 10a, 10b comprises a swivel bolt bracket 11a and a swivel bolt cover 11b. Each swivel bolt bracket 11a is bent in a U-shape around the swivel axis S of the respective swivel bolt 10a, 10b and has two legs 13 ( Fig. 1 and 6 ).

To mount the swivel bolts 10a, 10b, they each have a base plate 58 which is in positive and / or non-positive engagement with the respective swivel bolt bracket 11a. For this purpose, the swivel bolt bracket 11a comprises a cutout 60 in the region of the swivel axis S and a recess 62 on each leg 13 in an outer region spaced apart from the swivel axis S. The base plate 58, on the other hand, has a coupling section 66 which is complementary to the cutout 60 and protrusions 64 which are complementary to the recesses 62 on.

In the assembled state of the bolt lock, the coupling section 66 is received in a form-fitting and / or non-positive manner in the cutout 60 of the swivel bolt bracket 11a and the projections 64 are each received in the corresponding recesses 62 of the swivel bolt bracket 11a. Apart from this, the base plate 58 is arranged in the assembled state of the bolt lock essentially between the two legs 13 of the swivel bolt bracket 11a.

The housing 12 comprises a front housing section 14 and a rear housing section 16, which are connected to one another by means of a connecting section 18 and which each hold a swivel bolt 10a, 10b in the direction of its swivel axis S on opposite sides of the housing 12. The housing 12 further includes a cover 20 which covers the front housing section 14.

As especially with the help of the in Fig. 3 The side view of the bolt lock shown can be seen, the front housing section 14, the rear housing section 16 and the connecting section 18 are connected to one another in such a way that the housing 12 is H-shaped in the longitudinal profile or in the longitudinal section. If, however, the bolt lock has only one swivel bolt 10, the individual sections of the housing 12 can also be arranged such that the housing 12 is U-shaped in longitudinal section.

Based on 2 and 3 it can be seen that a longitudinal extension of the housing 12 is at least approximately at right angles to the respective pivot axis S of the pivot bolts 10a, 10b. Also show 2 and 3 a swivel bolt 10a (upper swivel bolt 10a) which is in the unlocking position and which is aligned at least approximately parallel to the longitudinal extent of the housing 12, and a swivel bolt 10b (lower swivel bolt 10b) which is at least approximately at right angles to the longitudinal extension of the housing 12 is aligned. It understands It is clear that the pivot bolt 10b, which is in the securing position, could also be pivoted through 180 ° in the opposite direction if the door or window is designed accordingly.

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

The fastening means 22 are preferably each in the form of a thread-forming screw. Furthermore, a fan dowel for receiving the fastening means 22 can be provided in a cavity for each fastening means 22.

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

In order to block the swivel bolts 10a, 10b which are in the securing positions, the bolt lock also has a blocking means 26. The blocking means 26 is at least approximately parallel to a blocking position between the swivel bolts 10a, 10b which prevent them from pivoting and a release position which releases the swivel bolts 10a, 10b Swivel axes S of the swivel bolts 10a, 10b are displaceable.

So that the blocking means 26 always blocks the swivel bolts 10a, 10b in their securing positions, a spring means 28 is provided which acts on the blocking means 26 in the direction of its blocking position. In the exemplary embodiment shown, the spring means 28 is designed in the form of two helical compression springs, each of which is supported at one end in the front housing section 14 and at the other end in a pocket 32 formed on a collar section 30 of the blocking means 26.

How especially based on Fig. 1 and 4th can be seen, the blocking means 26 each have a collar section 30 on opposite sides. The collar sections 30 not only serve to receive one end of the helical compression springs, but also prevent the blocking means 26 from blocking the swivel bolts 10a, 10b in their unlocking positions. For this purpose, each collar section 30 of the blocking means 26 located in the release position is supported on a section of an end face 34 of the swivel latches 10a, 10b which is in the unlocked position and is at least approximately perpendicular to the respective swivel axis S of the corresponding swivel latch 10a, 10b.

On a side of a respective collar section 30 opposite the pocket 32 or on a side facing the corresponding swivel bar 10a, 10b, each collar section 30 has a latching projection 35 ( Fig. 4 ) which, in the unlocked position of the pivot bolt 10a, 10b, into a latching groove 37 (provided on the pivot bolt 10a, 10b) ( 2 and 3 ) engages and prevents unintentional pivoting of the pivot bolt 10a, 10b into the securing position.

If the swivel bolts 10a, 10b are swiveled from their unlocking positions into their safety position, the respective end faces 34 of the swivel bolts 10a, 10b slide past the collar sections 30 and the blocking means 26 is shifted due to the spring force of the spring means 28 from the release position into the blocking position.

In the blocking position of the blocking means 26, a section of a longitudinal side surface 36 of the respective pivot bolt 10a, 10b, which is oriented approximately perpendicularly to the end face section 34, is supported on an outer surface 38 of the collar sections 30 of the blocking agent 26 located in the blocking position.

To move the blocking means 26 out of its blocking position into its release position, a driver 40 is provided which, together with the blocking means 26, forms a ramp mechanism. The blocking means 26 is shifted against the spring force of the spring means 28.

The driver 40 is mounted at least in sections in a passage 41 of the blocking means 26 so as to be rotatable about an axis of rotation Da. In addition, the driver 40 is coupled to a core 42 of a locking cylinder 44 which can be rotated about an axis of rotation Db between an unlocking position and a locking position. For this purpose, the driver 40 has a web 46 facing the core 42, which engages with a slot 48 provided on the core 42 in a positive and / or non-positive manner. The core 42 is rotated by means of a suitable key 50.

When the core 42 is rotated from the locking position into the unlocking position, the driver 40 coupled to the core 42 is also rotated. Here, two extensions 52 formed in the passage 41 of the blocking means 26 and at least approximately parallel to the central axis M of the blocking means 26 each run on a ramp 54 formed on the driver 40 and the blocking means 26 is released from the blocking position against the spring force of the spring means 28 in the release position shifted. The two ramps 54 formed on the driver 40 for the extensions 52 of the blocking agent 26 surround the axis of rotation Da of the driver 40 like a double spiral. Each of the ramps 54 has two stops 56, which limit a rotational movement of the driver 40.

The shifting of the blocking means 26 from the blocking position into the release position takes place against the spring force of the spring means 28, whereby the blocking means 26 is pretensioned to a certain extent. When the swivel bolts 10, 10a, 10b are pivoted into their respective securing positions, the spring force of the spring means 28 causes the blocking means 26 to be automatically shifted from the release position into the blocking position, in particular when the core 42 of the locking cylinder 44 is in the locking position. If the swivel bolts 10, 10a, 10b assume their security positions, the swivel bolts 10, 10a, 10b are mutually supported by the blocking means 26, whereby a particularly high level of security against burglary of the bolt lock can be achieved.

How especially based on Fig. 1 It can be seen that the axis of rotation Db of the core 42 of the locking cylinder 44, the axis of rotation Da of the driver 40 and an at least approximately parallel to the displacement direction of the blocking means 26 and center axis M running through the blocking means 26 are coaxially aligned with each other. In addition, the axis of rotation Db of the core 42, the axis of rotation Da of the driver 40 and the central axis M of the blocking means 26 are at least approximately parallel to the respective pivot axes S of the pivot bolts 10a, 10b, which run on opposite sides of the blocking means 26.
