Abstract
Description
Technical Field
[0001] The present application relates to a bolt lock having a lock body and a bolt that can be selectively inserted into the lock body and locked to the lock body. In particular, the bolt lock can be configured as a two-wheeled vehicle frame lock. Background Art
[0002] Such a bolt lock can be used to selectively fix a first object and a second object to each other. For this purpose, the lock body can be permanently mounted to the first object. The bolt can be associated with the second object, whereby the bolt can be connected, for example, to a chain or a wire rope (metal cable, in particular a steel cable), which is the second object or can be connected to the second object. For example, one object (the first object or the second object) can be a fixed anchor (for example, a building wall, a bicycle stand or a lamp post), while the other object (the second object or the first object) is a selectively fixed two-wheeled vehicle (for example, a bicycle or an electric bicycle).
[0003] If the bolt lock is configured as a frame lock of a two-wheeled vehicle or a frame lock for a two-wheeled vehicle, the bolt lock may include a lock catch (in particular a linear lock catch), which is configured to pass through the spoke wheel of the two-wheeled vehicle in the closed state, thereby ensuring that the two-wheeled vehicle is not driven away without authorization, wherein the free end of the lock catch includes a bolt. On the other hand, in the open state, the lock catch can be retracted from the space in which the spoke wheel is rotated to ride the two-wheeled vehicle so as to release the two-wheeled vehicle for riding. Such a frame lock can, for example, be mounted to the frame of the two-wheeled vehicle or integrated into the frame of the two-wheeled vehicle. In this context, a "two-wheeled vehicle" is to be understood as a vehicle having at least two wheels, i.e., for example, a cargo bicycle having three wheels. The bicycle can be human-powered, motor-powered or motor-assisted, in particular by an electric motor.
[0004] In order for such a screw latch to reliably perform its fixing function, it is important that an authorized user correctly operates the screw latch, in particular locks the screw latch. Summary of the invention
[0005] An object of the present application is to provide a screw latch of the aforementioned type which supports proper use by authorized users.
[0006] This object is achieved by a screw bolt lock having the features of claim 1 .
[0007] The screw bolt lock comprises a lock body and a screw bolt, which can be selectively inserted into the lock body and locked to the lock body in the inserted state. The lock body comprises a lock core, which can be actuated between an initial position and an actuated position by rotational actuation around the lock core axis using a relevant key. The lock core may have a movable bolt, which can be arranged by the relevant key according to the coding of the relevant key. The lock core can be configured as a disk lock core with a rotatable disk bolt, a plate lock core with a linearly adjustable plate-shaped bolt, or a pin lock core with a pin bolt. For example, the lock core can have a lock core housing and a lock core core, which can be rotated in the lock core housing relative to the lock core housing and has an introduction channel for introducing the relevant key.
[0008] The lock body further comprises: a lock bolt movable between a locking position and an unlocking position; and a blocking member movable between a blocking position and a releasing position. The lock cylinder, the lock bolt and the blocking member may be, for example, held or supported in a common housing of the lock body.
[0009] The latch of the lock body in its locked position locks the inserted screw to the lock body. In the unlocked position, the latch releases the inserted screw for removal from the lock body. By actuating the lock cylinder into the actuated position using an associated key, the latch moves to the unlocked position and can in particular also remain in the unlocked position as long as the lock cylinder is in the actuated position.
[0010] The key can only be removed from the lock cylinder in the initial position of the lock cylinder. The initial position of the lock cylinder can also be referred to as the zero position. On the other hand, in the actuated position of the lock cylinder, i.e. when the lock bolt is moved into its unlocked position, the key is fixed in the lock cylinder and cannot be removed from the lock cylinder. In particular, it can also be provided that the key is captured in the lock cylinder in an intermediate position between the initial position and the actuated position of the lock cylinder, so that the key can only be removed from the lock cylinder in the initial position.
[0011] This fixing of the inserted key in the lock cylinder can be achieved in particular by a movable locking bolt of the lock cylinder. For example, the lock bolt (in particular, a disk lock bolt or a plate lock bolt) can have a corresponding introduction opening for the key, whereby the lock bolt is adjusted by inserting the key into the lock cylinder and / or by turning the inserted key, and thereby a stop is formed, against which a coding feature of the key (e.g. height, contour of the corresponding introduction opening) directly or indirectly abuts, thereby preventing the key from being pulled out of the lock cylinder until the lock cylinder returns to the initial position. Alternatively or additionally, it is possible that the lock bolt (in particular the pin bolt) engages in a coding recess (e.g. a notch or a hollow) of the key and the lock bolt does not move back out of the coding recess as long as the lock cylinder is not returned to the initial position (e.g. when the core hole for the pin bolt and the receiving hole are aligned). The inserted key can also be fixed in the lock cylinder by a fixing element, for example, which engages around the tip of the key in a form-fitting manner, thereby preventing the key from being pulled out of the lock cylinder as long as the key is not in the zero position corresponding to the initial position of the lock cylinder.
[0012] In the blocking position of the blocking element, the blocking element of the lock body blocks the actuation movement of the lock cylinder into its initial position. In this way, the blocker prevents the removal of the key from the lock cylinder. On the other hand, in its release position, the blocking element releases the lock cylinder for its actuation movement to the initial position, so that the lock cylinder can be actuated to the initial position using the associated key and the key can be removed from the lock cylinder again. The blocking element and the bolt are configured such that the bolt moves the blocking element into the release position when the bolt is inserted into the lock body, and in particular, the bolt also holds the blocking element in the release position as long as the bolt is inserted into the lock body.
[0013] The combination of a bolt and a blocking member, each of which interacts with a screw inserted into the lock body, together with the lock cylinder forms an automatic key fixing function. Thus, an authorized user (i.e. the owner of the relevant key) can only remove the key from the lock cylinder when the screw is inserted into the lock body, thereby moving the blocking member to the release position. On the other hand, the key cannot be removed after the unlocking actuation and after the screw is removed, because in this state, the blocking member prevents the lock cylinder from being actuated to the initial position. Instead, the user is forced to reinsert the screw into the lock body in order to move the blocking member to the release position, so that the lock cylinder can be actuated to the initial position (corresponding to the locked position of the bolt). Thus, the user may not easily forget to correctly lock the screw to the lock body, because otherwise the user may not be able to remove the key and take it with him.
[0014] Other embodiments of the present application are explained below.
[0015] In some embodiments, the lock cylinder can be actuated between an initial position and an actuated position without the need for a spring support, such as a torsion spring, which would preload the lock cylinder to one position or another. Instead, it can be arranged that the lock cylinder must be actively actuated in both directions by an associated key.
[0016] In some embodiments, when the lock cylinder is in the initial position, the lock bolt is in the locked position. Thus, when the lock cylinder is in the initial position, the bolt inserted into the lock body is reliably locked, and the key can thus be removed. Thus, it is ensured that when the key is removed from the lock cylinder, the bolt is locked to the lock body.
[0017] In some embodiments, the bolt may be pre-tensioned in the direction of the locked position. As a result, automatic locking may be achieved. This means that, as the bolt is inserted into the lock body, the bolt is automatically locked to the lock body, whereby the bolt is temporarily pushed back from the bolt against its pre-tensioning and then locked into engagement with the bolt. Subsequently, the lock cylinder may be actuated to its initial position and the key may be removed from the lock cylinder. Suitable drive ramps may be formed on the bolt and / or the bolt to drive the latch against the pre-tensioning caused by the bolt.
[0018] In some embodiments, when the bolt is removed from the lock body, the blocking member is in the blocking position. As a result, even if the bolt is not inserted into the lock body, the lock cylinder can be prevented from being actuated to its initial position.
[0019] In some embodiments, the blocking element can be pretensioned in the direction of the blocking position. As a result, a particularly reliable operation of the screw bolt lock can be achieved, since the blocking element generally prevents the lock cylinder from being actuated into its initial position without the locking bolt actively resisting its pretensioning movement into its release position. In particular, the blocking element can be driven to move into the release position by the screw bolt, i.e. by inserting the screw bolt into the lock body. For this purpose, suitable driving bevels can be formed on the blocking element and / or the screw bolt.
[0020] In some embodiments, the latch and the blocking member can be mounted and pretensioned in a floating manner by a common preload spring. In particular, the latch and the blocking member can be pretensioned in opposite directions. In particular, the latch can be pretensioned in the direction of the locking position and the blocking member can be pretensioned in the direction of the blocking position at the same time, whereby a single pretensioning device (e.g. a compression spring) is required.
[0021] In some embodiments, the lock cylinder may include a rotatable cam. The cam may be rotated by actuating the lock cylinder between an initial position and an actuated position. For example, the cam may be directly coupled to a rotatable lock cylinder core of the lock cylinder (e.g., as one piece). The cam may be configured to transmit a driving motion generated by an associated key to the latch. The cam may move along a circular path around the lock cylinder axis.
[0022] In some embodiments, the cam of the lock cylinder may include a drive portion that drives the latch in the direction of the unlocked position of the latch when the lock cylinder is actuated to the actuated position.
[0023] Alternatively or additionally, the cam may comprise a stop portion which abuts the blocking element when the blocker occupies the blocking position and the lock cylinder is actuated from the actuated position towards the initial position. In other words, when the user attempts to bring the lock cylinder into the initial position by rotational actuation using an associated key, the stop portion of the lock cylinder abuts the blocking element in its blocking position, which prevents the lock cylinder from reaching the initial position.
[0024] In some embodiments, the blocking member may include a blocking portion and a releasing portion, wherein in the blocking position of the blocking member, the blocking portion blocks the cam of the lock cylinder to prevent the lock cylinder from actuating and moving into the initial position, and wherein, in the releasing position of the blocking member, the releasing portion releases the cam of the lock cylinder for the lock cylinder to actuate and move into the initial position. In particular, the releasing portion of the blocking member may be retracted relative to the blocking portion relative to the movement direction of the cam.
[0025] In some embodiments, the bolt can be inserted into the lock body along a bolt insertion direction, in particular along a straight line, wherein the key can be inserted into the lock cylinder along a lock cylinder axis, and wherein the lock cylinder axis is oriented perpendicular to the bolt insertion direction. Thus, the lock cylinder can be actuated by a user using an associated key outside the movement path of the bolt. As a result, undisturbed operation of the lock cylinder is possible. In addition, by rotational actuation of the lock cylinder, in particular by the above-mentioned cam of the lock cylinder, a simple and effective drive of the bolt and / or the blocking member is possible.
[0026] In some embodiments, the latch and the blocking member may be mounted to be linearly movable, ie, to move in a straight line.
[0027] In some embodiments, the latch may comprise a flat bearing portion which extends along a plane perpendicular to the axis of the lock cylinder and which can be moved perpendicularly to the axis of the lock cylinder, wherein the blocking element also comprises a flat bearing portion which extends along a plane perpendicular to the axis of the lock cylinder and which can be moved perpendicularly to the axis of the lock cylinder and parallel to the latch. In particular, the bearing portion of the latch and the bearing portion of the blocking element can abut against each other to form a mutually linear guide. As a result, the latch can be mounted in the blocking element in a particularly simple and low-volume manner. In particular, the latch and the blocking element can be mounted on the underside of the lock body and / or the lock cylinder, resulting in a particularly flat structure of the lock body.
[0028] In some embodiments, the latch and the stopper may be configured as stamped and folded metal sheets.
[0029] In some embodiments, the latch may include a locking portion that projects laterally, particularly vertically, from a supporting portion of the latch. The locking portion of the latch may be configured to engage with an engagement recess of the bolt, particularly the above-mentioned engagement recess, when the latch is in the locked position.
[0030] In some embodiments, the blocking member may include a driving portion that protrudes laterally, in particular vertically, from a supporting portion of the blocking member. A driving ramp may be formed at the driving portion of the blocking member (in particular the aforementioned driving ramp), through which the bolt can drive the blocking member to move to the release position due to the bolt being inserted into the lock body.
[0031] In some embodiments, the bolt may have an engagement recess in which the latch engages in the locked position. In particular, the engagement recess may be configured as a circumferential recess. The bolt may have a generally cylindrical insertion portion inserted into the lock body. In some embodiments, the bolt may have an insertion slope and / or a drive slope at its free end, in particular a shape with a conical or frustoconical tip. The drive slope of the bolt may cooperate with the latch and / or the blocking member so that the latch or the blocking member is pushed back as a result of the insertion of the bolt into the lock body.
[0032] The present application also relates to a frame lock for a two-wheeled vehicle or for a two-wheeled vehicle, wherein the frame lock comprises a bolt lock of the above type and a lock catch (in particular a linear lock catch), the lock catch being configured to pass through the spoke wheel of the two-wheeled vehicle in a closed state, wherein the free end of the lock catch comprises the above bolt. For this purpose, the lock body can be mounted to the frame part of the two-wheeled vehicle or integrated into the frame part of the two-wheeled vehicle (whereby the frame part can form the housing of the lock body). The lock catch can be inserted into the insertion opening of the lock body along a linear insertion direction, and the insertion opening points in the direction of the spoke wheel. In this closed state, the end of the lock catch (bolt) can be locked to the lock body. Thus, as explained, the spoke wheel is prevented from rotating, and the relevant key can be removed from the lock cylinder. If the lock catch is subsequently unlocked by actuating the lock cylinder accordingly, the lock catch can be removed from the movement path of the lock body and the spoke wheel. In this open state, the two-wheeled vehicle is released for riding, whereby the key is fixed at the lock body. In the open state, the lock catch can be permanently connected to the lock body or completely separated from the lock body. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The accompanying drawings show a possible embodiment of a bolt lock including a lock body 11 and a bolt 21, wherein the bolt 21 can be selectively inserted into the lock body 11 along the bolt insertion direction E and locked in the lock body 11 ( Figure 1The lock body 11 comprises a housing 13 having an insertion opening 15 for a bolt 21 .
[0042] In the housing 13, the lock body 11 comprises: a lock cylinder 31 (not shown separately), which can be moved in an initial position ( Figure 1 ) and actuation position ( Figure 6C ) is actuated between; the latch 41 ( Figure 2 and Figure 3 ), can be in the locked position ( Figure 5A ) and unlocked position ( Fig. 6A ) moves between; and the blocking member 51 ( Figure 2 and Figure 3 ), can be in blocking position ( Figure 4A ) and release position ( Figure 5A )
[0043] The key 33 can be inserted into the lock cylinder 31 along the lock cylinder axis A, whereby the lock cylinder axis A is oriented perpendicular to the bolt insertion direction E. The lock cylinder 31 is configured so that the lock cylinder 31 and the key 33 are inserted into the lock cylinder 31 only when the lock cylinder 31 and the key 33 are in the initial position ( Figure 1 , Figure 5C ) to release the inserted key 33 for removal.
[0044] The latch 41 and the blocking member 51 are mounted so as to be movable in a straight line. The latch 41 and the blocking member 51 are mounted in a floating manner and are supported by a common preload spring 43 ( Figure 3 ) are pre-tensioned in opposite directions. The preload spring 43 is sandwiched between the latch 41 and the blocking member 51.
[0045] The latch 41 has a flat bearing portion 45 extending along a plane perpendicular to the cylinder axis A and movable perpendicular to the cylinder axis A. The bearing portion 45 comprises a control opening 47. The blocking member 51 also comprises a flat bearing portion 57 extending coplanarly with the bearing portion 45 of the latch 41 along a plane perpendicular to the cylinder axis A and movable perpendicular to the cylinder axis A and parallel to the latch 41, wherein the bearing portion 45 of the latch 41 and the bearing portion 57 of the blocking member 51 abut against each other, thereby forming a linear mutual guidance. The latch 41 also comprises a locking portion 49 protruding vertically from the bearing portion 45 of the latch 41 and configured to engage in the circumferential engagement recess 23 of the bolt 21 in the locked position. The blocking member 51 comprises a drive portion 59 protruding vertically from the bearing portion 57 of the blocking member 51. A driving slope 61 is formed at the driving portion 59 of the blocking member 51, through which the bolt 21 can push back the pre-tensioned blocking member 51 due to its insertion into the lock body 11. In addition, the blocking member 51 includes an elongated semi-cylindrical recess 63 between the support portion 57 and the driving portion 59, and the preload spring 43 is accommodated in the recess.
[0046] The lock cylinder 31 comprises a cam 35 which can be driven by rotational actuation to be rotationally moved about the lock cylinder axis A by a key 33 inserted into the lock cylinder 31. To this end, the cam 35 is non-rotatably connected to the underside of a rotatable lock cylinder (not shown) of the lock cylinder 31. The cam 35 has a generally circular segmented shape and engages in a control opening 47 of a bearing portion 45 of the latch 41. The cam 35 comprises a drive portion 37 and a stop portion 39. Depending on the position of the blocking member 51, the stop portion 39 of the cam 35 interacts with a blocking portion 53 or a release portion 55 of the blocking member 51, as will be explained below.
[0047] The function of the screw latch shown is explained below with reference to Figures 4 to 7, wherein the three illustrations in Figures 4 to 7 respectively show the screw latch in a bottom view (A), a stereoscopic view partially cut away from above (B) and a stereoscopic view from above (C).
[0048] According to FIG. 4 , the bolt 21 is not or not fully inserted into the lock body 11 . The key 33 is located in the lock cylinder 31 ( Figure 4C ). The lock cylinder 31 is in an intermediate position between the initial position and the actuated position. The lock bolt 41 and the blocking member 51 extend into the movement path of the bolt 21 in the housing 13 due to their respective pretensioning. Figure 4A and Figure 4B As shown, the stop portion 39 of the cam 35 abuts the blocking portion 53 of the blocking member 51. Thus, the blocking member 51 is in a blocking position in which the blocking member 51 blocks the lock cylinder 31 from actuating movement into the initial position. As a result, the cam 35 and therefore the key 33 are prevented from being able to rotate to the initial position ( Figure 1 ). This rotational movement towards the initial position will be Figure 4A In the clockwise direction, and in Figure 4C Proceed in counter-clockwise direction.
[0049] According to FIG. 5 , the bolt 21 is completely inserted into the lock body 11 and locked in the lock body 11. For this purpose, the latch 41, after being temporarily pushed back by the tip of the bolt 21 against the force of the preload spring 43, is in the locked position and engaged due to its pretensioning, wherein the locking portion 49 of the bolt 41 is in the engagement recess 23 of the bolt 21. By inserting the bolt 21 into the lock body 11, the blocking member 51 has been pushed back by its driving ramp 61 into the release position against the force of the preload spring 43, and in this position, the blocking member 51 releases the lock cylinder 31 for its actuation movement to the initial position. For this purpose, the release portion 55 of the blocking member 51 is located at the height of the cam 35 of the lock cylinder 31. Thus, the stop portion 39 of the cam 35 can now be released by turning the key 33 to the initial position ( Figure 5A) and rotate in the release portion 55 of the blocker 51. In the initial position of the lock cylinder 31 thus reached, the key 33 can be removed from the lock cylinder 31 ( Figure 5C ). At this time, the bolt 21 is locked to the lock body 11.
[0050] According to Figure 6, the lock cylinder 31 is now in the actuated position. To this end, the key 33 is rotated approximately 90 degrees from Figure 5, i.e. relative to Fig. 6A The bottom view of the counterclockwise rotation and relative to Figure 6C This rotation of the key 33 causes a corresponding rotation of the cam 35, so that the drive portion 37 of the cam 35 drives the latch 41 toward the unlocked position of the latch ( Fig. 6A ). In the unlocked position, the latch 41 releases the latch 21 to be removed from the lock body 11.
[0051] According to FIG. 7 , the bolt is removed from the lock body 11 . The key 33 is still in the actuated position. However, due to its pretensioning, the blocking member 51 returns to the blocking position ( Fig. 7A ). Starting from the actuated position, the key 33 can now be returned towards the initial position. However, the lock cylinder 31 may not be completely moved to the initial position, because the stop portion 39 of the cam 35 eventually abuts against the blocking portion 53 of the blocker 51, as explained with respect to FIG. 4. As a result, the key 33 is stuck in the lock body 11.
[0052] As a result, the screw bolt lock shown has an automatic key fixing function. Only when the screw bolt 21 is locked in the lock body 11, the user could remove the key 33 from the lock cylinder 31 and take it away.
[0053] It should also be noted that for the bolt lock shown in the figures, the lock can also be part of a frame lock of a two-wheeled vehicle or part of a two-wheeled vehicle, whereby the frame lock has a straight or curved lock shackle, the end of which forms the bolt 21.
