  • the locking pin is pushed manually, mechanically through the cylindrical housing from the outside with respect to the lockable space “outer” side to the lockable space inside “inner” side, after which the locking pin exits the inside of the door leaf and locked in the opening direction against the inside of the door frame.
  • the two positions of the locking bolt "open” and “closed” can be locked by means of a key inserted in the profile cylinder, and can only be converted into one another by turning the key, thus providing a practical and simple way of locking sliding doors.
  • a bolt lock is described, in which a locking bolt is provided with a locking nose, which can dip into two tangential recesses of the housing, and thus locks the positions "open” and “closed” cylindrical housing is formed by an axially extending slot in the housing limited, in which a bolted with the locking bolt cylinder head screw out, and at the same time prevents rotation of the locking pin in the housing.
  • the disadvantage of the above-mentioned closing mechanisms is that the closable bolt lock forms a temperature bridge.
  • this bolt locks in cold stores cools the protruding into the cooling chamber locking pin part very strong. The cold is passed to the outside via the locking pin forming a cold bridge, where water vapor contained in the air then condenses on and in the outer locking bolt part containing the profile cylinder. The resulting condensate freezes on and in the cold locking bolt, whereby a species-appropriate use of the bolt lock is no longer possible, which is a problem especially in the event of an emergency opening the sliding door.
  • a lockable bolt lock according to claim 1 wherein the locking pin has two parts, wherein the parts of the locking pin are displaceable relative to each other to form a thermally insulating gap.
  • the dependent claims relate to individual embodiments of the bolt lock according to the invention.
  • the lockable bolt lock consists of a two-part cylindrical housing which is composed of an inner housing part located in relation to the lockable space and an outer housing part located externally with respect to the lockable space, and a two-part slidingly mounted in this cylindrical housing Locking bolt, wherein the inner locking pin part is coupled to a provided between the two locking pin parts disc.
  • the inner locking bolt part may also be coupled to a screw.
  • the two locking bolt parts are displaceable relative to each other in the axial direction, whereby the formation of a thermally insulating gap is made possible, which interrupts the temperature bridge between the inside and the outside of the closable space.
  • a first advantageous embodiment of the invention provides housing parts in which the radius of the inner housing part is smaller than that of the outer housing part.
  • the two housing parts are then inserted from the inside and from the outside into the door leaf of the sliding door, and then firmly connected.
  • the connection can be done by a screw, a bond or in another convenient way.
  • a small plate is attached to the outer periphery of the outer housing part for preventing rotation. This can be screwed, glued or welded.
  • the housing is designed to be telescopic, so that an adaptation to different door leaf thicknesses is possible in an advantageous manner.
  • the telescopic adjustment allows advantageously a far-reaching adaptation to different door thicknesses only by telescoping the two housing parts, said housing parts have corresponding locking means formed to each other, for example in the form of partial threads, so that by a simple rotation of the two housing parts relative to each other for example by 45 ° 135 ° is formed a force-transmitting connection between the two housing parts.
  • the housing can thus be mounted in a simple manner by the two housing parts are rotated into each other and relative to each other.
  • the handle is designed such that a simple Handling is guaranteed, even in the event that the operator wearing gloves, which complicate the handling in terms of limited by the gloves fine motor skills of the hand.
  • the handle can be configured in the form of a recess, a handle-like handle, such as a knob, or in any other appropriate manner.
  • a handle can be dispensed according to an alternative embodiment of the invention also.
  • An operation is then carried out for example via a key to be introduced into a profile cylinder.
  • a further advantageous embodiment according to a first alternative of the invention provides that the inner locking pin part can be locked in the closed position.
  • the inner locking pin part can be locked in the closed position.
  • the disc and the inner locking pin part are coupled to each other via a firmly connected to the disc, mushroom-shaped pin.
  • the mushroom-shaped pin attached to the inner side of the disc passes centrally through the inner locking pin portion in a cylindrical bore therewith, which has a larger radius at the inner end of the inner locking pin portion to form a shoulder and receive the mushroom head.
  • a locking element as a blocking element, which is designed to be movable transversely to the locking pin and / or an actuating element. The locking is then done via this bar, which can also be referred to as a trap.
  • the actuator may be formed as described in the form of a mushroom head, as a ball, as a cylinder or in any other appropriate manner.
  • a coupling member is attached to the outer side of the disc, which allows the coupling of the outer locking pin member to the disc, and thus to the inner locking pin member.
  • a recess for receiving the coupling member is provided in the outer locking pin part.
  • the coupling itself takes place via a rotation of the key in the profile cylinder, whereby a closing lug engages the coupling member. If now pulled in the coupled state on the handle of the outer locking pin part, the compression spring between the actuating element and the shoulder is compressed at the cylindrical bore of the inner locking pin part, a small gap between the disc and inner locking pin part is formed and the locking of the inner locking pin part is released whereby the opening of the lock can take place.
  • the coupling member may be formed as a mushroom-shaped extension, as a hook-shaped extension or in another expedient form.
  • the coupling member is mounted eccentrically on the disc according to a further advantageous embodiment of the invention to achieve a larger angle of rotation.
  • a further advantageous embodiment of the invention provides to prevent rotation of the disc and the outer locking pin member guide elements on the disc and the outer locking pin part, which are guided in a housing groove extending in the longitudinal direction.
  • the guide elements can be designed as a screw, as a pin or in another convenient way.
  • a further advantageous embodiment of the invention provides a clamping device on the outer locking pin part, which engages in a recess on the outer inner circumference of the outer housing part.
  • the clamping device is formed according to an advantageous embodiment of the invention as a retractable in the radial direction into the outer locking pin member clamping member which is urged radially outwardly by a pressure spring located in the outer locking pin part.
