Description

The present invention relates to a hinge lock with automatic function. Such a hinge lock comprises a lock body housing a lock mechanism and a hinge bar bracket having a plurality of pivotally connected hinge bars and a lock bar. A first end of the hinged bar is permanently attached to the latch body and a second end of the hinged bar comprises the striker. The Gelenkstabbügel is folded into a folding rule configuration in which the joint rods and the locking bar parallel to each other. The lock body has a receiving opening, wherein the closing rod can be locked by inserting the closing bar into the receiving opening of the lock body by means of the locking mechanism on the lock body.

Such a hinge lock is used, for example, for securing a bicycle to a bicycle stand, a lamp post or the like, or for securing a bicycle against unauthorized driving away. For this purpose, the hinged behind one another or in a row hinge rods of the Gelenkstabbügels are unfolded to form an open loop, which is guided for example to a frame portion of the bicycle and the bicycle stand, lamp posts or the like or is guided only by a rim of the bicycle. Then, the locking bar, which forms the second, free end of the hinge bar, is locked to the lock body to thereby close the loop and thus secure the bicycle against unauthorized removal or unauthorized driving away.

For the transport of the hinge lock by the authorized user, the joint rods and the locking bar can be folded into a compact arrangement - the so-called folding rule configuration. For this purpose, the joint rods and the closing rod are pivoted in the manner of a foldable folding rule and thereby brought into a parallel alignment with each other.

In order to simplify the handling of the hinge lock during locking, an automatic function can be provided. This means that by inserting the locking bar into the receiving opening of the lock body, the closing bar (and thus the second end of the hinged bar handle) can be automatically locked to the lock body by means of the locking mechanism. For example, the locking mechanism may comprise a biased latch, which is temporarily moved by inserting the locking rod into the receiving opening of the lock body counter to the bias from a closed position to a release position and snaps back to the closed position due to the bias once the locking bar completely inserted into the receiving opening is. Thus, a locking of the locking bar on the lock body is made possible without requiring an active operation of a lock cylinder, for example by means of an associated key is required.

A hinge lock with automatic function according to the preamble of claim 1 is known from DE102013210475A1 known.

When not in use, a hinge lock of the type mentioned in a storage device (eg bag or quiver) can be stored and transported, as these from the DE202005013390U1 is known. For this purpose, the Gelenkstabbügel is folded into the said compact rule rule configuration. Typically, such a storage device comprises a holding portion, which surrounds the folded hinged rod bracket circumferentially, wherein the lock body protrudes from the holding section in order to be gripped by the user for removal of the hinge lock.

In a joint lock with automatic function, it may prove to be disadvantageous that the locking mechanism for a desired securing a bicycle must nevertheless be actively actuated (for example by means of an associated key), namely after removal from a storage bag, first the second end of the hinged bar strap or to release the lock bar from the lock body and thereby form an open loop. If, on the other hand, the closing bar is designed to be shortened only so that the hinged bar handle can be folded without the locking bar being inserted into the lock body, the handling of the hinged bar bar will be impaired since the closing bar can then swing out undesirably in the folding rule configuration according to its articulated connection.

It is therefore an object of the invention to provide a hinge lock with automatic function, which is even easier to handle.

This object is achieved by a hinge lock with the features of claim 1 and in particular by the fact that in the folding rule of the Gelenkstabbügels the locking bar is only partially inserted into the receiving opening of the lock body, without the locking bar is locked to the lock body.

The hinge lock according to the invention simplifies the handling during the locking process, since not only an automatic function for locking the locking bar is provided on the lock body, but also for the previous unfolding of the hinged bar handle to form an open loop of the locking mechanism does not have to be actively operated. Instead, the hinge lock can be stored folded in the compact ruler configuration and transported, wherein after removal from a corresponding storage device of the Gelenkstabbügel can be unfolded directly to an open loop. The hinge lock thus combines the advantages of an automatic function of the locking mechanism with a simple handling when attaching the hinged rod bracket to the bicycle for securing the same.

The lock body and the hinge bar are adapted to allow the hinge bar to adopt the folding rule configuration while the lock bar is partially inserted into the receiving opening of the lock body without the lock bar being already locked to the lock body. The Gelenkstabbügel thereby assumes - although the locking bar is not locked to the lock body - a stable transport position. Characterized in that the locking bar already protrudes into the receiving opening of the lock body, but without being already locked to the lock body, the lock bar in one or more directions, for example, two mutually opposite directions, be supported by the lock body. This support of the relevant portion of the locking bar can be done for example by a part of a housing of the lock body. This allows the Gelenkstabbügel form compared to a free pivoting of the locking bar an arrangement that is sufficiently stable for comfortable handling (for example, a grasping and embracing the Gelenkstabbügels by the user). This stable transport position is made possible in a structurally simple manner by the length of the lock bar is selected accordingly and the arrangement of the locking mechanism is matched in the lock body to the length of the lock bar.

According to an advantageous embodiment of the locking bar may be blocked by a lateral boundary of the receiving opening of the lock body against pivoting, when the locking bar only partially into the receiving opening the lock body is inserted and not yet locked to the lock body. Thus, it can be prevented in a simple manner that the locking bar in the folding rule configuration of the hinged bar handle according to its articulation to the adjacent joint rod unintentionally swings laterally, as long as the locking bar is not yet locked to the lock body. Preferably, the locking bar is blocked in two mutually opposing pivoting directions against pivoting when the locking bar is only partially inserted into the receiving opening of the lock body.

In particular, a boundary of the receiving opening of the lock body surrounding the inserted into the receiving opening closing bar circumferentially. Preferably, the respective end of the closing rod is enclosed by the boundary of the receiving opening substantially form-fitting.

The locking bar, which is initially only partially inserted into the receiving opening of the lock body, can thereby be locked automatically to the lock body such that the lock bar is completely inserted into the receiving opening of the lock body.

According to one embodiment, the lock body and the hinge rod bracket are adapted so that the hinge rod bracket can be brought into the folding rule configuration only when the locking rod is not locked to the lock body. As a result, it is immediately apparent to the user that the hinge lock is not in the locked state, namely when the hinge bar handle assumes the compact ruler configuration.

If the Gelenkstabbügel can take the folding rule configuration only when the lock bar is not locked, can be prevented inadvertently or accidentally, for example, during transport by vibration of the locking bar by fully inserted into the receiving opening on the Lock body is locked, in particular by the Gelenkstabbügel held by a storage device in the folding rule configuration (for example, circumferentially embraced) is.

In particular, the lock body and the hinged bar handle can be adapted so that the hinged bar handle inevitably assumes a configuration deviating from the folding rule configuration when the lock bar is locked to the lock body.

According to one embodiment, the locking bar may have a length that is less than a length that would be required for the locking bar to be inserted into the receiving opening of the lock body and locked to the lock body in the folding rule configuration of the hinge bar strap.

Further, the locking bar may have a length which is greater than a length that would be required so that would not be inserted into the receiving opening of the lock body and would protrude into the receiving opening in the folding rule configuration of the hinged bar handle the locking bar.

As regards the automatic function locking mechanism, it may comprise a latch and biasing means biasing the latch to a closed position, the latch being temporarily moved against the bias from the closed position to a release position by incomplete insertion of the latching rod into the receiving aperture of the latch body wherein the biasing means is adapted to move the latch back to the closed position when the locking bar is fully inserted into the receiving opening. In particular, the closing rod can take an intermediate position by said incomplete insertion into the receiving opening, which between the position of the closing rod in the said partially Insertion and said complete insertion is in the receiving opening.

For cooperation with the latch, the locking bar may have a locking portion which is operatively engaged with the latch in the closed position of the latch to lock the locking bar to the latch body. The locking portion of the locking bar may include, for example, a protrusion, a recess or an opening.

The bolt may be formed, for example, as a rotary latch, as a pivot bolt or as a linear displaceable latch.

The locking mechanism may comprise a lock cylinder, wherein by actuation of the lock cylinder by means of an associated key, the bolt is temporarily movable against the bias from the closed position to the release position to release the lock rod for removal from the receiving opening of the lock body.

As regards the attachment of the hinged rod bracket to the lock body, the first end of the hinge rod can be permanently attached directly to the lock body, to a laterally projecting from the lock body attachment portion, or on a laterally projecting from the lock body connecting rod.

The first end of the hinge bar can be rigidly or pivotally connected to the lock body.

According to one embodiment, the lock body may extend along a longitudinal axis, wherein the first end of the hinged bar handle at a laterally projecting from the lock body and rigidly connected to the lock body Attachment portion or connecting rod is permanently attached, and wherein the receiving opening of the lock body is provided with respect to the longitudinal axis of the lock body in alignment with the attachment portion or connecting rod. In other words, the first end and the second end of the Gelenkstabbügels can be arranged on the same side of the lock body in alignment with each other. This allows a particularly compact form of the hinge lock in the folding rule configuration of the hinge rod bracket, when the closing rod is hereby partially introduced as explained in the receiving opening of the lock body.

Preferably, in the folding rule configuration of the hinged bar handle, the longitudinal axes of the hinge bars and the closing bar extend in a plane parallel to each other.

Further, it is preferred if the lock body extends along a longitudinal axis or said longitudinal axis, wherein the longitudinal axis of the lock body extends within a plane which is spanned in the Zollstock configuration of the Gelenkstabbügels of the longitudinal axes of the hinge rods and the closing rod.

Alternatively or additionally, the lock body can extend along a longitudinal axis, wherein in the folding rule configuration, the joint axes of the joint rods of the hinge bar are parallel and the longitudinal axis of the lock body is parallel to the joint axes of the joint bars.

Furthermore, it is preferred if, in the folding rule configuration of the hinged bar handle, the lock body is arranged within an extension plane of the hinge bar strap, so that the lock body and the hinged bar handle together form a flat package.

According to one embodiment, the closing rod can be introduced axially with respect to its longitudinal axis into the receiving opening of the lock body. Alternatively, however, a lateral pivoting into the receiving opening is possible.

The hinge rods of the hinge bar are preferably formed straight and formed flat relative to their length and width.

Further, it is preferable if the first end of the hinge bar is permanently attached to a first end of the lock body, wherein the receiving opening of the lock body is provided for inserting the lock bar at a second end of the lock body.

This in Fig. 1 shown hinge lock 10 includes a lock body 12 and a hinged rod bracket 14 attached thereto. The lock body 12 houses a locking mechanism with automatic function. In the unlocked state of the hinge lock 10 of the Gelenkstabbügel 14 can be unfolded to form a known per se, an open loop that can be placed around parts of a bicycle or other objects. The free end of the Gelenkstabbügels 14 can then be automatically locked by means of the locking mechanism on the lock body 12 that the free end of the Gelenkstabbügels 14 is completely inserted into the lock body 12. As a result, the loop formed is closed, and the bicycle is locked or secured to the object in question (eg bicycle stand).

The Gelenkstabbügel 14 includes a plurality of hinge rods 16 and a closing rod 18. The hinge rods 16 and the locking bar 18 are each formed flat. The articulated rods 16 and the locking bar 18 are hinged together in sequence by a respective rivet 22 such that the articulation axes are parallel or coaxial with each other. The Gelenkstabbügel 14 can thereby be folded as shown in a so-called ruler configuration to a compact unit in which the hinge rods 16 and the locking bar 18 in a plane parallel to each other. A first end 24 of the Gelenkstabbügels 14 is hinged to the lock body 12. A second end 26 of the Gelenkstabbügels 14 is formed by the free end of the locking bar 18, which serves to lock the locking bar 18 on the lock body 12, as will be explained below.

On the lock body 12, a lock cylinder 30 is accessible via a key opening 28, in which a key 32 can be inserted to actuate the lock cylinder 30 by turning a cylinder core. The lock body 12 further comprises a receiving opening 34 into which the locking bar 18 can be inserted along its longitudinal axis. When the locking bar 18 in the receiving opening 34th is inserted, the closing rod 18 is surrounded by the peripheral boundary of the receiving opening 34 substantially form-fitting manner.

Fig. 2 shows the hinge lock 10 according to Fig. 1 in a schematic representation. In Fig. 2 For example, the hinge axes 36 of the hinges between the hinge bars 16 and the lock body 12 (at the first end 24) and the lock bar 18 (at the second end 26) are shown.

The essential elements of the locking mechanism housed in the lock body 12 are shown in FIG Fig. 2 shown in dashed lines. Evident are the lock cylinder 30, coupled to the lock cylinder 30 movable latch 38, and a biasing spring 40 which biases the lock cylinder 30 in the direction of rotation and thereby also the bolt 38 in the direction of a Fig. 2 biased shown closed position. Further, at the end of the locking bar 18, a locking protrusion 42 can be seen.

In the in Fig. 2 As shown, the locking bar 18 is only partially inserted into the receiving opening 34 of the lock body 12. The locking bar 18 is thereby not yet locked to the lock body 12. Instead, the locking projection 42 of the locking bar 18 is viewed in the insertion direction even before the latch 38. The hinge lock 10 is thus in an unlocked state, the hinge rod bracket 14 as explained assumes the folding rule configuration.

In this transport position of the Gelenkstabbügels 14, the hinge lock 10 can be conveniently stored in a storage device (eg bag or quiver) and carried along, which encompasses the compact folded hinge rod bracket 14 circumferentially. Characterized in that the locking bar 18 protrudes into the receiving opening 34 of the lock body 12 in the unlocked state of the hinge lock 10 and thereby against unintentional pivoting is blocked, the Gelenkstabbügel 14 forms a stable arrangement that can be comfortably grasped and held by the user, for example, even if the user first takes the hinge lock 10 for removal from said storage device only on the lock body 12.

For the user is in the in Fig. 2 also immediately apparent that the hinge lock 10 is not in the locked state, since the Gelenkstabbügel 14 can take the rule configuration only in the unlocked state.

Fig. 3 shows in one of the Fig. 2 corresponding representation of the hinge lock 10 in a state in which the locking bar 18 is now locked to the lock body 12. For this purpose, the closing rod 18, starting from the position according to Fig. 2 even deeper, but initially incomplete inserted into the receiving opening 34 of the lock body 12, whereby the latch 38 was temporarily pushed back from the locking elevation 42 of the locking bar 18 against its bias from the closed position to a release position. As a result of the subsequent complete insertion of the locking bar 18 in the receiving opening 34 such that the locking elevation 42 of the locking bar 18 has moved past the latch 38, the biasing spring 40 via the rotatable lock cylinder 30, the latch 38, however, has moved back into the closed position, so that the latch 38 engages behind the locking projection 42 and the in Fig. 3 shown state has been achieved. This pushing back and re-snapping the latch 38 is in Fig. 3 illustrated by the double arrow R. As a result of the complete insertion of the closing bar 18 into the receiving opening 34, the closing bar 18 was thus automatically locked to the lock body 12 without an active actuation of the lock cylinder 30 by means of the key 32 being required (automatic function).

However, this complete insertion movement of the locking bar 18 into the receiving opening 34 is only possible in the hinge lock 10 when the Gelenkstabbügel 14 according to the folding rule configuration Fig. 1 and 2 leaves. In Fig. 3 This is evident from the fact that the four central hinge rods 16 rest in an oblique orientation on the lock body 12, ie in relation to the representation according to FIG Fig. 3 the four central hinge rods 16 are swung out of the plane of the paper. Also the in Fig. 3 Joint rod 16 shown on the right is pivoted, so that in the projection according to Fig. 3 its effective length is reduced.
