Description

The invention relates to a long bar lock with a in an elongated lock body dipping both ends Bracket, arranged with a in the lock body Locking mechanism for moving locking means arranged in a at the free ends of the bracket Leg sections locking or unlocking position, with a substantially tubular housing for Receiving the locking means and the locking mechanism and with one on each end side inside of the housing-arranged U-shaped Armor.

Such a long bar lock is for example from the DE 43 22 989 C2. The tubular housing is by welding a U-shaped profile piece with a Bottom plate made. For mounting are in this Long bow lock the parts of the locking mechanism between the legs of the U-shaped profile piece inserted and with this pinned from the bottom plate ago. The square tube has besides the holding function for the parts of the locking mechanism the functions of the radial Armor of the lock body and in closed position the long bar lock securing the temple ends against spreading. Another surrounding the lock body outer cover housing is usually made of plastic manufactured and serves to the long bar lock to give pleasing appearance.

This long bar lock has the disadvantage that security against attempts to break through solely through the tubular Housing and through the at the head sides through the Cover housing easily accessible parts of the lock mechanism must be guaranteed. Therefore, the tubular Housing be designed very thick walls, so that the Recesses for the leg sections of the bracket in tubular housing a Aufspreizversuch on the long bar withstand. Furthermore, the accessible to the head end Parts of the lock mechanism accordingly stable be formed. However, these parts exist because of their complicated shape, on the other hand, the requirement make them from easily processable material. Such material is then usually quite soft or im Case of zinc diecasting brittle and therefore in attack attempts easy to destroy. The pinning of the parts can usually just overcome and the parts pulled apart become.

To increase the security on the head sides is in the known long bar lock provided that to the Head-facing parts in the tubular housing through the U-shaped trained as a metal bracket armor are surrounded. It closes the bottom of the U-shaped Metal clamp the head side partly outwards. The both legs have openings that when closed Long bow lock penetrated by the ends of the temple and secured by this against Ausziehversuche are. When only absorbed by the tubular housing Spreading forces on the bracket so this can not the U-shaped metal brackets are supported. The corresponding thick-walled design of the tubular housing and lead the additional U-shaped metal brackets so to a considerable weight of the long bow lock, what with the entrainment as a bicycle lock of large Disadvantage is.

The invention is based on the problem Long handle lock of the type mentioned above to further develop that it is particularly easy to install and in particular in the longitudinal direction of the lock body acting spreading forces supported as reliable as possible.

This problem is inventively achieved in that the bottoms of the U-shaped armor the associated ends the tubular housing is substantially complete fill in and parallel to the extension direction of Lock body pointing legs of the U-shaped armor Recesses and / or hooks have, with corresponding recesses and / or hooks of Bracing for positive connection of the two U-shaped armor inside the case mesh.

Due to this design, the lock body has a closed armor, so that the components of the Locking mechanism and the locking means reliable even in an attack attempt by its end pages the U-shaped armor are protected. Because the U-shaped Armor over the bracing means with each other contribute to increase the stability of the Lock body against spreading at. The tubular Housing supported by this particular by spreading the temple caused longitudinal forces especially Reliable. The positive connection is disposed within the tubular housing and thus not available for attacking. The Longbügelschloss invention can be in the simplest case with the U-shaped Armor, the bracing and the Pre-assemble locking mechanism as a structural unit and from an open end into the tubular housing introduce. As a result, the long bow lock according to the invention can be achieved easy to assemble. Furthermore, can the tubular housing of the invention Langbügelschlosses made of a thinner walled material be considered the case of the well-known Longbügelschlosses. This contributes to a particularly low weight and low Material costs of the elongated bow lock according to the invention at. The low weight of the invention Long bow lock simplifies its entrainment, for example in a two-wheeler. The hanger of the invention Langbügelschlosses can as in the known Long bar lock rigidly designed or formed by a cable be.

In the assembled and locked state of the invention Long bar lock will be the U-shaped Armor held reliably when the tubular Housing for holding the positive connection of the bracing means designed with the U-shaped armor. This allows the internal components of the invention Do not disassemble the long-handle lock until the tubular housing is completely dismantled. The complete Disassembly of the tubular housing, however by the guidance of the leg sections to be locked of the bracket through the tubular housing largely prevented.

The bracing means are made according to another advantageous development of the invention particularly cost, if they have a protective plate. Farther This makes the bracing means particularly special easy to assemble.

In a Aufspreizversuch the bracket on the lock body transmitted forces are according to another advantageous Development of the invention particularly reliable supported when the U-shaped armor locked in State at the leg portions adjacent projections having. By this design are in the Aufspreizversuch the tubular housing and the U-shaped armor simultaneously engaged with the leg portions of the temple.

To further increase the supportable from the lock body Forces during the expansion attempt it carries according to a another advantageous development of the invention, when the legs of the U-shaped armor bends with a recess for receiving the free ends of Have leg portions of the bracket.

The insertion of the leg sections in the lock body designed according to another advantageous development The invention particularly simple when the leg sections at their free ends in each case to a conical Section subsequent pins have. Furthermore, the pin in the recess of the bend penetrate the U-shaped armor. By the Cross section reduction through the conical section on the cones, the bending can be wide and therefore very be stably designed.

To further increase security against an attack attempt through the open ends of the tubular Housing carries it according to another advantageous embodiment the invention, when in the region of the ends the tubular housing within the U-shaped armor a reinforcing member is arranged.

To further simplify the assembly of the invention Longbow lock carries it according to another advantageous development in when the tubular housing with the U-shaped armor through recesses passed through the tubular housing and in the U-shaped armor penetrating pins is connected.

The long bow lock according to the invention requires particular few components to be mounted when the pins are transverse to the Axis of the leg portions of the bracket aligned and in the farthest from the protective plate third of Lock body are arranged. Through this design require the locking means only a single Protection plate for connecting the U-shaped armor.

In the unlocked and in the locked state of the invention Longbow lock are the tubular housing reliably connected to the U-shaped armor, when the pins for connection of the tubular housing in pairs, arranged opposite each other are and if arranged between the pins a transverse plate is. This design allows the pins not be pushed out of the tubular housing. This contributes to further increase the safety of the invention Longbow castle against destruction at.

A forwarding of one of the leg sections transferred to the locking mechanism in the lock body Forces to locking means of the other leg portion is according to another advantageous embodiment the invention reliably prevented when a Lock cylinder of the locking mechanism in the protective plate is stored. By this design, the leg sections individually and thus essentially independent held each other in the lock body.

The lock body sets according to another advantageous Development of the invention a Durchtrennungsversuch a particularly high stability when the tubular Housing and the U-shaped armor of different Materials are made.

To further increase the stability of the lock body against a Durchtrennungsversuch it carries according to a another advantageous development of the invention, when between the tubular housing and the U-shaped Armor is arranged one layer and that the Layer is made of a different material than that tubular housing. When made of sheet steel tubular housing, this layer can, for example Ceramic included.

The lock body is too easy to mount pre-assemble handling assemblies when the U-shaped Armoring centering means for a locking mechanism and locking means have leading holding part.

To reduce weight and manufacturing costs the long bar lock according to the invention contributes, if the holding part is made of plastic.

In general, the locking mechanism or the locking means a spring element for biasing in a intended position. The support of the spring element on a fixed component designed constructively especially easy if the protective plate is a tab for Supporting a for biasing the locking mechanism and / or the locking means designed spring element having.

The locking means are according to another advantageous Development of the invention particularly constructive easy to set up, if one of the locking mechanism movable and framed to lock the bracket Lock bolt of the locking means at least one has elongated frame. For a high stability the frame is preferably self-contained.

The lock body is designed according to another advantageous Development of the invention particularly compact, when the spring element for biasing the locking means arranged within the frame of the locking bolt is.

To further reduce the weight of the invention Longbow lock adds to it when the frame The locking bolt is made of plastic when the for locking with the leg portions of the bracket provided ends of the locking bolt in each case a reinforcing element and if the reinforcing elements have larger dimensions than for the introduction of the leg sections of the bracket provided in the tubular housing Recesses.

To further reduce the dimensions of the lock body the long bar lock according to the invention carries it at, when the reinforcing member having area the locking bolt directly to the tubular housing is applied.

The lock body sets when acting on the bracket tensile forces a particularly high resistance to, if the locking bar fork-shaped, the leg section laterally designed at least partially encompassing. As a result, the locking bolt on the tubular Support housing. Therefore, no component is bent claimed.

The reinforcing element is particularly cost-effective and has a large contact surface on the Leg section on when the reinforcing element as Roll is formed.

The spring element could, for example, directly supported on the frame made of plastic. A Damage to the frame by the spring element can be however, according to another advantageous development of the invention simply avoid when in the context of Locking bar arranged a support block for the spring element is.
