Definitions

  • the invention relates to a lock, in particular a door lock, with a locking bolt that can be rotated back and forth between a locking position and an unlocking position, a lock holder in which the locking bolt can engage in the locking position, and a stop that limits the rotational movement of the locking bolt.
  • closures are used in many areas of technology, for example for closing flaps, doors, hatches or similar elemen th.
  • a door is used below to represent these elements.
  • Corresponding closures usually have a locking bar which can be rotated back and forth between a locking position and an unlocking position and which can be, for example, a sash tongue.
  • the locking bar is usually arranged on the inside of a door and can be rotated back and forth between the locking position and the unlocking position from the outside of the door via an actuating element such as a handle lever.
  • the locking bolt ensures that the door cannot be opened, since the locking bolt engages in a frame-side lock holder in this position and the door is thus fixed in relation to the door frame.
  • the locking bolt In order to open the door, the locking bolt must first be turned into the unlocking position in which the locking bolt no longer engages in the locking holder and in which the door can be opened with respect to the frame.
  • a stop limiting the rotational movement of the locking bolt is also provided as a rule.
  • the locking bar When the locking bar is in the unlocked position, it rests against the stop so that no further rotation into the unlocking opening is possible.
  • the reason for this stop is that it is often not desirable if the locking bolt can be rotated freely, since, for example, with a complete rotation in the unlocking direction, the locking bolt would nevertheless engage in the lock holder again.
  • the stop can ensure that the locking bar can only be rotated into the unlocked position and not beyond it.
  • the door When the locking bolt is in the unlocked position, the door can be moved and moved about a mostly vertically oriented pivot axis.
  • Doors There are essentially two types of Doors, namely doors hinged on the right, in which the stop or pivot axis of the door is on the right side and doors are hit on the left, in which the stop or pivot axis is accordingly on the left side. Although this happens much less often, it is also possible to strike doors at the top or bottom.
  • the handle can usually be dismantled and then turned around, dismantling is usually associated with a not inconsiderable amount of work, especially if the screws to be loosened are not readily accessible.
  • the invention has the task of specifying a closure that can be adapted more easily.
  • the stop is designed as an interchangeable stop which can be used to provide different stop positions in different stop receptacles.
  • the position of the stop can be changed, for example, depending on whether the door is to be hinged on the left or right, so that the lock and thus also the door can be easily converted.
  • a handle lever and thus also the locking bar can be freely rotated into the desired position after removing the interchangeable stop.
  • the stop can optionally be used in one of the different stop mounts, depending on the requirements.
  • the stop is releasably connected to the respective stop receptacles. This made light a simple and quick arrangement of the stop on the respective stop receptacle.
  • the stop can be switched from one stop seat to another stop seat.
  • the stop can be removed from one of the stop receptacles very easily and without the use of additional tools, in particular pulled out, and then inserted into the other stop receptacle. This thus enables a very simple and intuitive repositioning of the stop and conversion of the lock.
  • the stop can be screwed or locked into the respective stop receptacles.
  • the stop is used in a stop position to limit the movement of the locking bolt in the case of a left-hinged door and in a stop position to limit the movement of the locking bolt in a right-hinged door.
  • the stop receptacles or the stop positions assigned to the stop receptacles can accordingly be matched to the door stop so that the stop can be switched from one stop receptacle to another stop receptacle in order to convert the door. It has also been found to be advantageous if two stop receptacles are provided in which the same stop can be optionally inserted.
  • the locking bolt it has been found to be advantageous if it is designed as a double locking bolt with two locking elements.
  • the design as a double locking bolt offers the advantage that a locking bolt has two different locking positions and unlocking positions. This has also proven to be advantageous in terms of convertibility.
  • the two locking elements can be opposite one another or be offset by 180 ° so that the locking bolt can have a propeller-like shape.
  • a locking element In the unlocked position, a locking element can engage in the lock holder to lock the door, and when moving into the unlocked position, the other locking element can strike a stop that prevents the locking bolt from moving beyond the unlocked position.
  • the locking latch and thus also the handle lever do not move more than 180 ° when moving between the locking position and the unlocking position Degree must be moved.
  • the locking bar it is also possible for the locking bar to have only one locking element.
  • the locking bolt as a double locking bolt, it has been found to be advantageous if one of the locking elements for locking the door can engage in the lock holder and the other locking element can strike the stop to limit the rotational movement. Which of the two locking elements engages in the lock holder and which strikes the stop can depend on the stop of the door. In the case of a door hinged on the left, for example, the locking element that engages in the lock holder to lock the door can be the locking element that strikes the stop in the unlocked position of a door hinged on the right and prevents further movement of the locking bolt in the unlocking direction .
  • the locking bolt it has also proven to be advantageous if it is rotatably mounted in a bolt housing.
  • the locking bolt can be moved back and forth between the locking position and the unlocking position, for example, via a handle lever, the handle lever being arranged on the outside of the bolt housing and the locking bolt being arranged on the inside of the bolt housing.
  • An actuating shaft which connects the handle lever to the locking bolt, can extend through the bolt housing.
  • a gear can also be provided so that the handle lever is not connected to the locking bolt directly, but rather via the gear.
  • the bolt housing can act as a cover and cover the locking bolt in such a way that it is not visible from the outside. This can prevent manipulation and also protect the internal mechanics from contamination and external influences.
  • the bolt housing can be arranged on the door side, in particular In particular, the bolt housing can be arranged on an outside of the door.
  • stop receptacles it has proven to be advantageous if these are arranged on the bolt housing. With this arrangement, the stop can be arranged very easily in different positions on the latch housing. The other components of the lock then do not have to be changed when retrofitting.
  • the stop receptacles are designed as insertion openings into which the stop can optionally be inserted. The stop can be easily inserted from the outside through the insertion openings and no de-assembly of the bolt housing is required. The corresponding insertion openings can extend from the visible front side of the bolt housing, on which the handle is also arranged, into the interior of the bolt housing, so that they are easily accessible.
  • the insertion openings can be closed by means of a cap, so that, for example, no contaminants can penetrate into the interior of the bolt housing via the insertion openings.
  • the stop can also be screwed, clipped or latched into the insertion openings.
  • the insertion openings can extend through the front of the bolt housing up to or into the opposite side of the bolt housing.
  • stop it has been found to be advantageous if it is designed as a stop pin or as a stop screw. Stop pins can thus be inserted very easily into one of the two insertion openings and then limit the rotational movement of the locking bolt accordingly. Stop screws can be screwed into the stop mounts, which may require the use of a screwdriver, but at the same time the stop can be held particularly securely in the Riegelge housing by this design. According to an alternative embodiment, it has been found to be advantageous if the stop receptacles are arranged on the lock holder. This refinement makes it possible that the bolt housing does not have to have any insertion openings and, in this respect, the various stop receptacles cannot be seen from the outside either.
  • the stops arranged on the lock holder can only be changed when the door is open. This can lead to better manipulation security, since the stops are not visible and also not accessible when the door is closed. At the same time, the stops can be changed very easily and, in particular, by hand, even if the stop receptacles are arranged on the lock holder.
  • the stop has a locking stop surface for limiting a rotational movement in the locking direction and an unlocking stop surface for limiting the rotational movement in the unlocking direction. This enables only a single stop to be required both to limit a movement in the locking direction and to limit a movement in the unlocking direction.
  • the stop can have two locking surfaces which are opposite one another and of which only one surface is used depending on the stop position. This can be the unlocking stop surface that faces the locking bolt located in the locking position. The surface opposite this unlocking stop surface can rest on the contact surface of the stop receptacle.
  • the unlocking stop surface and the locking stop surface can be arranged perpendicular to one another.
  • the stop can be cube or square be shaped and the two locking stop surfaces can be arranged on opposite sides of the cube or cuboid.
  • the lock holder it has been found to be advantageous if it has a mounting element via which the lock holder can be fastened in a mounting plane on a door frame, a holding element and a holding surface which is spaced apart from the mounting plane and which is supported by a door-side Ver - the locking bolt for locking the door can be reached from behind.
  • a corresponding de lock holder design has proven itself in the past.
  • the holding surface it has proven to be advantageous if the holding surface and the mounting plane are arranged parallel to one another. This makes it possible that the locking bar also rests as completely as possible on the holding plane in the locking position, which ensures good power transmission and thus a secure hold of the locking bar.
  • the holding surface can also be arranged parallel to the surface of the door frame. It is not absolutely necessary for the holding surface to be a flat surface, but rather the holding surface can also be curved in sections, for example
  • the Hal teelement is connected to the mounting element via two supports.
  • the holding element can be arranged at a distance from the mounting element in parallel, so that the holding element, together with the two supports, has a substantially C-shaped contour.
  • the supports can be arranged perpendicular to the assembly plane and perpendicular to the holding surface, so that the holding surface also runs parallel to the assembly plane.
  • the two supports can be connected to the holding element at the respective edge areas of the holding element, so that between the enough space remains for both supports and the door-side locking bar can grip behind the holding element or the holding surface during a rotary movement.
  • the holding element is connected in one piece to the supports and to the mounting element.
  • the holding element, the supports and the assembly element can thus be produced in one work step and designed, for example, as an injection-molded part. This enables simple and inexpensive series production.
  • the Stoppaufnah men can receive the stop positively so that the stop then no longer move in at least one direction, in particular in two directions, relative to the stop receptacle can.
  • the stop recordings can, however, be designed in such a way that the stop can be removed from the stop recordings against the assembly direction.
  • the stop receptacle can have a counter-stop against which the stop can rest when it is located in the stop receptacle.
  • the stop receptacle comprises a recess extending into the holding element and / or into the mounting element.
  • the recess can serve to guide the stop so that it can be pushed into the stop receptacle in the assembly direction.
  • the recesses can also extend into the holding element and / or into the mounting element in the mounting direction.
  • the mounting direction can extend parallel to the mounting plane and to the holding surface.
  • the recess can be designed as an elongated hole, so that the stop can be received in the recess in a form-fitting manner.
  • the stop receptacle it has proven to be advantageous if it comprises two recesses extending parallel into the holding element and / or into the mounting element.
  • the holding element can be arranged parallel to the mounting element, so that a reliable mounting of the stop can be ensured through the cutouts.
  • This configuration has proven itself with regard to a reliable retention of the stop.
  • the stop has guide elements, in particular guide pins, via which it is guided in the recesses. Due to the interaction of the guide elements and the recesses, the position of the stop in the stop receptacle can be firmly defined and even if the locking bar or the locking elements of the locking bar strike the stop, the locking bar cannot move it.
  • the number of recesses can agree with the number of guide elements. Furthermore, with regard to the stop receptacle, it has proven to be advantageous if it has a contact surface for contacting the stop.
  • the contact surface can also ensure that the stop is reliably held in the corresponding stop position.
  • the stop surface can be part of a support via which the holding element is connected to the mounting element.
  • the contact surface can in particular serve to absorb forces acting on the stop when the stop has only one insertion element.
  • the stop In order to connect the stop to the stop receptacle, it has been found to be advantageous if the stop can be connected to the lock holder via a holding shoe that can be slipped onto the holding element.
  • the Hal- The shoe can be latched to the holding element of the lock holder, so that the holding shoe must first be removed from the holding element in order to release or change the position of the stop. No additional tool is needed to remove the retaining shoe or to remove the stop from the corresponding stop holder.
  • the retaining shoe has two legs of different thicknesses.
  • the two legs can extend parallel to each other, and when the retaining shoe is connected to the retaining element, one leg can be arranged on the side of the retaining element facing away from the mounting plane and one leg can be arranged on the side of the Hal teelements facing the mounting plane.
  • the surfaces of the legs can be designed as sliding surfaces so that the locking bar can slide on these surfaces in the event of a locking or unlocking. During locking and unlocking, the locking bar always slides on the surface of the leg that faces the mounting level in the corresponding mounting position. Furthermore, it has been found to be advantageous if the retaining shoe has a U-shaped cross section. A corresponding cross-section allows the holding shoe to be slipped onto the holding element from one direction and, in particular, to be able to grip around the holding element in a form-fitting manner.
  • the holding shoe it has proven to be advantageous if it has at least one spring arm, via which the holding shoe can latch with the holding element and / or the support (s). Via the spring arm, the holding shoe can thus be releasably connected to the Hal teelement and securely held on it.
  • the spring arm (s) can each have one or more latching lugs which ensure that the spring arm (s) deform automatically when the retaining shoe is slipped onto the retaining element and then automatically engage behind the retaining element or supports when the end position is reached.
  • the spring arms and the latching lugs are advantageously designed in such a way that the holding shoe can then also be removed from the holding element again without the additional use of tools.
  • the spring arms can be arranged on the side of the retaining shoe and grip around the Hal teelement and / or the supports in the assembly positions like a clamp.
  • the holding shoe has four spring arms.
  • One Fe can be arranged derarm on each side of the leg.
  • the four spring arms can have locking lugs that all point in one direction. In the Mon day position, the locking lugs of two spring arms can engage behind the Hal teelement, in particular the locking lugs of the spring arms, which are arranged on the side of the narrower leg.
  • the holding element can have a guide for the holding shoe.
  • the guide can prevent the holding shoe from catching or tilting when it is pushed onto the holding element, which in this respect further simplifies the assembly and disassembly of the holding shoe.
  • the guide can comprise two guide webs which are used for linear guidance of the holding shoe. In the connected position, the holding shoe can be arranged between these two webs.
  • the guide has proven to be particularly advantageous when the holding shoe has four spring arms and / or if the holding shoe is designed to be shorter than the holding element.
  • the holding shoe it is also possible for the holding shoe to extend over the entire length of the holding element.
  • an additional guide on the holding element is not absolutely necessary, but the spring arms, which can laterally encompass the holding element and / or the supports, can serve to guide the guide shoe ge compared to the holding element.
  • the retaining shoe holds a guide element of the stop in the stop receptacle.
  • the holding shoe can thus ensure that the stop is held securely in the stop receptacle.
  • the corresponding guide element of the stop can extend through the recess from the stop receptacle and then be held or secured in this receptacle by the holding shoe.
  • the retaining shoe thus ensures a form-fitting recording of the stop in the stop recording.
  • the holding shoe can preferably encompass a guide element of the stop at least in sections.
  • the holding shoe can have one or more receptacles which, in the connected position, are aligned with the recesses of the stop receptacles in such a way that the holding shoe can be received in a form-fitting manner.
  • the recesses can be designed as elongated holes and extend between the legs and the spring arms of the holding shoe.
  • the stop has a recess so that a spring arm of the holding shoe can move through the sen return can extend.

If the holding shoe 5 and in particular the corresponding surfaces of the holding shoe 5 on which the locking bar 7 slides have good sliding properties, this reduces the risk of material being removed. In addition, if the pressure of the locking bolt 7 on the retaining surface 3 is too high, the retaining shoe 5 may also take the retaining shoe 5 with it when the locking bolt 7 is rotated into the unlocking position E and thus pull it off the retaining element 2 . In this respect, good sliding properties also enable the holding shoe 5 to be held securely on the holding element 2. Possible materials for the holding shoe 5 are, for example, plastic, in particular POM, brass or bronze. Furthermore, surface coatings can also be used in order to improve the sliding properties.
