Definitions

  • the invention relates to a lock, in particular a panic lock for a door of a refrigerator or freezer.
  • Locks of this type serve to be able to close a door on the one hand from the outside, so that from the outside no unauthorized person can penetrate, on the other hand, however, ensure that from the inside always the door can be opened.
  • Such doors are used for escape routes, emergency exits and the like, in particular, they are also in refrigerators and freezers regulation, to ensure that a person accidentally trapped in it at any time can leave the room.
  • Mortise locks which have this function, are state of the art. They have on their inward and outward sides door handle, which engage via a common square in a rotatably mounted inside the lock nut.
  • the nut has a driver with which the latch can be moved in the opening direction.
  • a lock cylinder is incorporated, which controls a parallel to the latch, usually arranged below bar, which can be extended by turning the key in the cylinder lock and retracted.
  • an operating element is firmly connected to the cylinder lock, so that the door can be unlocked from the inside even without a key.
  • DE 1 078 900 B describes a latch lock with two separately stored, independently operable pushers and additional latch feed, in which it is possible from the inside, by moving the pusher against the pusher movement in the opening direction, the trap further out of the castle and at the same time to block the other pusher. Although this lock always opening from the inside is possible, but no locking from the outside.
  • DE 429 316 C discloses a lock in which the trap is also usable as a bar.
  • the invention has the object, a lock in such a way that it can be easily opened as a panic lock of the réelleseitestets, however, is lockable from the outside.
  • the lock according to the invention which is provided and intended, in particular, as a panic lock for a door of a refrigerated or freezer compartment, has a chassis in which a lock latch, which is bevelled at least on one side, is displaceably guided, which is spring-loaded in the extension direction.
  • a nut is rotatably mounted, which is formed divided and has an inward Nussteil, which is actuated via an inward control lever.
  • This inward Nussteil has a driver with which the case is actuated at least in the retraction direction.
  • the other part of the nut is formed by the external Nussteil, which is actuated via an external control lever and having an external driver, with the case in the retraction and extension direction is actuated.
  • lock means are further provided according to the invention, which spend the driver of the nut parts in non-actuation of the operating lever in a neutral position in which the drivers are out of engagement with the trap.
  • means for locking the external driver are provided in its neutral position, which are operated from abroad.
  • the lock according to the invention is characterized in that the lock latch forms a lock rule and a first extended position is provided, in which only the case function is effective, and a second extending beyond extending position is provided as a locking function.
  • the basic idea of the lock according to the invention is to make the panic function of the lock as simple as possible, d. H. To enable an intuitive operation, as it is particularly advantageous in panic situations, as it can be performed almost without thinking by the person.
  • the lock according to the invention can also be, if this completed from the outside, d. H. is locked with respect to its operation, open at any time from the inside, by simple operation of the operating lever in the open position.
  • a commercially available door handle can be used, regardless of whether the lock has been locked from the outside or not, by simply pressing the inside, as when opening a room door open.
  • the advantage that on the inside only one operating lever is always to operate.
  • the lock according to the invention is particularly advantageous for the door of a cold room or freezer use, but the application is not necessarily limited thereto, it can also be used for other purposes as a panic lock or for other purposes.
  • the lock structure is designed so that the already existing latch also forms the lock bolt with which the lock can be moved to its locking position in the lock plate.
  • the design of the lock mechanism according to the invention is such that a first extended position is provided for the latch, in which only the case function is effective and that, moreover, a second, on the first extended position reaching outward position is provided, which fulfills the locking function.
  • the first extended position thus includes the usual snap function, in which the Lock case against spring force enters the lock, typically when the door is closed and the trap is pushed back with its inclined surface by the strike plate. In the second extended position, however, the latch is pushed further into the strike plate, so that a lock between lock and strike plate takes place, which is much more difficult to manipulate than that of the first extended position.
  • the latch bolt bevelled on both sides. It is in addition to the usual bevel, which comes when closing the door with the outside of the strike plate in contact to press the latch against spring force into the lock, also on the other side a bevel provided which is typically shorter and serves to Door mechanically by extending the latch bolt from the first extended position to the second extended position, still a piece to the frame, creating a particularly dense system, which ensures that the door seals over their entire length firmly fit and seal well.
  • a receptacle for a lock cylinder is provided according to a development of the invention in the chassis of the castle, which is designed so that the lock cylinder is accessible only from the outside, d. H. that it is only accessible from the outside of the castle with a key. From the inside, however, the lock is closed-walled in this area.
  • Such lock cylinders are available at low cost and can optionally be linked with locking systems, which are also used in other locks.
  • the driver of the lock cylinder is arranged so that when turning the key actuates a mechanism within the lock, which locks the outer Nussteil or unlocked, in the neutral position of the external driver, so that the operation of the inward Nußils and thus the latch is independent of it.
  • the lock cylinder is therefore not, as usual, a bolt extended out of the castle, but rather serves to fix the foreign Nussteil via a corresponding locking mechanism, so that an operation from the outside and thus opening the lock from the outside, no longer possible is.
  • each Nussteil is provided with an approximately tangential to the axis of rotation of the nut control surface directed at a spring-loaded slide, which is guided within the chassis and slidably to this according to a development of the invention Control surface, preferably at an angle of about 45 ° thereto, is spring-loaded.
  • This slide which has a counter-surface in neutral position against the control surface, is designed and arranged in such a way that that he automatically returns the Nussteil with his driver in the neutral position, as described in detail below.
  • a locking device is provided within the castle, which determines the driver of the respective nut part in its neutral position.
  • the springs of slide and locking device are therefore interpreted as meaning that the slider can automatically transfer the driver of the associated Nußils in the locked position.
  • the structure of the castle can be structurally simple and stable, if according to an embodiment of the invention, the chassis has a support plate which carries the components of the castle and which is connected on one longitudinal side with a forend, as is common in mortise locks.
  • the lock is advantageously designed as a mortise lock, so that it can optionally replace existing locks if they are to be replaced by such, inside equipped only with an operating lever panic lock.
  • the operating levers are advantageously formed by standard-compliant door handle, so that the lock can accommodate standard lever handle sets and can be used in standard doors without special designs.
  • the lock illustrated with reference to the figures is a mortise lock with a face plate 1 which can be inserted into a standardized recess of a folding or stump door and can be fastened in it by means of the forend 1.
  • the face plate 1 and a transversely arranged thereto and fixedly connected to the support plate 2 form the chassis of the castle, which is surrounded with a closed (not shown in the figures) rectangular housing, as is common in mortise locks.
  • the lock has a latch 3, which is bevelled on two sides and has a first long inclined surface 4, which is arranged on the inwardly facing side and which is provided for the usual snap function and intended when the door with the therein located lock is slammed and the inclined surface 4 impinges on the foreign side of the strike plate, whereby the latch bolt 3 is retracted against the spring force of the spring 5 through the forend 1 in the castle. After passing over the edge of the striker, the latch bolt 3 automatically moves out again by the force of the spring 5 and holds the door in the closed position. This position (first extended position) is in Fig. 1 shown.
  • the latch bolt 3 has a short inclined surface 6 which is shorter than the inclined surface 4 and is arranged on the outward side of the latch 4.
  • This inclined surface 6 serves to push it further into the strike plate when the lock catch 3 is already snapped into the strike plate, the lock catch 3 being pulled into the door frame by the inclined face 6 together with the lock and the door in which the lock is seated. thereby ensuring that the door seal is subjected to force and thus brought to bear on all sides.
  • the tightness of the door is ensured in refrigerator doors and thus prevents the flow of cold through the door gap.
  • the inclined surfaces 4 and 6 extend to near the free outer end of the latch 3.
  • the inclined surface 4 extends over almost the entire in the normal position protruding from the forend 1 part of the latch 3, whereas the inclined surface 6 is only about half of this Partly extends and then merges into a rectilinear part.
  • a nut consisting of two parts 7 and 8 is provided, which is rotatably mounted within the support plate 2 or the lock housing.
  • the outer Nussteil 7 has a central four-edged recess 9, which is provided for receiving an operating lever in the form of a door handle.
  • the inward Nussteil 8 also has a central square recess 9, the form-fitting Receiving an inward control lever is provided in the form of a door handle arranged on the inside of the door. Since the nut parts 7 and 8 are separated from each other, they can be moved independently.
  • Each Nussteil 7, 8 has a long driver 10 and 11, with the lock latch 3 can be locked and opened. In the case of Fig.
  • 1 illustrated position of the driver 10 and 11 is a neutral position in which the respective driver 10, 11 is fixed detent and is not in operative connection with the latch bolt 3.
  • the detent position is formed by a spring force loaded locking receptacle 12 in the castle.
  • a common spring for both drivers 10 and 11 is provided.
  • Fig. 1 In this neutral position, the in Fig. 1 is shown, the drivers 10 and 11 are disengaged.
  • the latch is also latching in the locking receptacle 12, so that they can not move the spring force of the spring 5 further.
  • the lock latch 3 is formed within the lock housing by a sheet metal part, in which recesses for supporting the nut parts 7 and 8 are formed and which has both on the inward and on the outward side a surface cutout to form two cam tracks 13 and 14.
  • Such cam tracks 13 and 14 are provided both on the inward and on the outward side of the latch 3 and are such that they can interact with the drivers 10 and 11 on the respective side in operative connection.
  • the long curved path 13 serves to move the latch from the normal position (first extended position) into the locked position (second extended position).
  • the short curved path 14 or the projection formed thereby in the latch 3 is used to open the lock, regardless of whether this is in the first or in the second extended position.
  • the lock In normal position, the lock is in the representation according to Fig. 1 , the latch 3 is in the first extended position in which it is held by the force of the spring 5 and the locking receptacle 12. In this position, the latch bolt 3 is arranged with respect to the cam tracks 13 and 14 at a distance from the respective drivers 10 and 11, so that the lock latch 3 z. B. against spring force can be pressed into the lock housing to exercise their snap function, without touching the drivers 10, 11.
  • Fig. 3 the lock is shown in a position in which it is brought into the locked position, ie in the second extended position.
  • Fig. 3c shows, by pressing the outside door handle against the opening direction, ie by pulling up the otherwise horizontal door handle.
  • the external Nussteil 7 with the driver 10 located in it Fig. 3c pivoted clockwise, whereby the driver 10 abuts the upper end of the cam track 13 and the further rotation of the latch 3 from its first extended position ( Fig. 1 ) moves in the locking position (second extended position), in which the inclined surface 6, the latch 3, attracts with the lock and the door to the door frame and the case 3 extends so far that it is no longer manipulated from the outside.
  • the Fig. 3c shows, by pressing the outside door handle against the opening direction, ie by pulling up the otherwise horizontal door handle.
  • the external Nussteil 7 with the driver 10 located in it Fig. 3c pivoted clockwise, whereby the driver 10 abuts the upper end of the cam track 13 and the
  • the latch 3 can be activated both by pressing the inward lever handle with the inward Nussteil 8 and by pressing the foreign door handle to be opened with the foreign Nussteil 7.
  • How to open the lock is based on Fig. 2 shown in which the external door handle is operated by opening by pressing down the door handle.
  • the lock catch 3 is moved not only from the second extended position, but also from the first extended position to the open position, in which the lock latch 3 is completely within the castle, the face plate 1 is therefore no longer penetrated by this outstanding.
  • the movement of the lock catch 3 takes place in this case by the external driver 10, which comes to rest on the short curved path 14 and takes the latch 3 in the retraction direction.
  • the driver 11 remains on the other (inward side) unchanged in its neutral position. It is understood that this opening movement can be done in the same way by making the inward door handle, so by pressing down the door handle located on the inside of the door.
  • two slides 16 are provided on both sides, which are in the installed position substantially vertically displaceable and spring-loaded by a spring 15 in the upward direction. They have an installation position about 45 ° to the vertical inclined inclined surface 17, which is in operative connection with an integrally formed in the nut parts 7 and 8 inclined surface 18, which is aligned approximately tangentially to the nut parts 7 and 8.
  • These inclined surfaces 18, which each extend between two short drivers 19 and 20, in conjunction with the inclined surface 18 on the respective slide 16 ensure that regardless of the position of the nut parts 7 and 8, these are automatically moved to their neutral position, in which the driver 10 and 11 are out of engagement with the lock latch 3. In this position, the inclined surface 17 of the slider 16 is flat against the inclined surface 18 of the associated nut.
  • a lock cylinder 21 (FIG. Fig. 5 ) integrated into the lock, which is accessible only from the foreign side, so from the outside of the door by means of a key.
  • the lock cylinder 21 has a driver 22 in a conventional manner, which moves a path around the cylindrical part of the lock cylinder when turning the key.
  • the lock cylinder with the driver 22 is clearly visible.
  • a sheet metal part 23 is slidable within the lock in the transverse direction, that is provided in the direction parallel to the direction of movement of the latch 3, which has a pawl 24 with which the outer Nussteil 7 can be locked by the pawl 14 is moved toward the forend 1 and thus the nut part 7 sets.
  • the driver 10 must be in its neutral position, since otherwise the pawl 24 is not inserted into the Nussteil 7.
  • the lockable lock cylinder 21 is therefore not usual as usual for locks, a bolt driven into the strike plate, but only blocks the movement of the external door handle and thus the operation of the lock latch 3 from the outside.
