Definitions

  • the invention relates to a rotary bolt with a housing and a lock insert rotatable in the housing but axially immovably mounted, which has a locking tongue or the like at its rear end protruding from the rear of the housing and at its front end within the housing for rotating the lock insert is provided with key surfaces for a removable key.
  • Such locking bolts are known in a variety of designs. If they are used on doors or flaps that are exposed to vibrations, there is a risk that the lock insert will twist in the housing, so that the door or flap inadvertently reaches the open position.
  • the invention has for its object to develop a rotary bolt of the type described in such a way that the lock insert is held vibration-proof in the locking position.
  • the solution to this problem by the invention is characterized in that at least one of the key surfaces of the lock insert is provided with a spring which is connected to a locking part protruding from the key surface, which engages in a recess in the housing at least in the locked position of the lock insert and that when placing the key on the key surface by pulling the spring is withdrawn from the recess.
  • a rotary bolt according to the invention achieves a form-fitting fixing of its lock insert in the locking position, this fixing being automatically removed when the key fitting on the lock insert is put on, by the key withdrawing the locking part from the recess in the housing via the spring assigned to the key surface, so that the lock insert can be easily turned into the open position with the key attached.
  • the locking part After turning the lock insert back into the locking position and removing the key, the locking part automatically arrives in the associated recess in the housing of the rotary bolt due to the spring action of the spring, which automatically causes the lock insert and thus the locking tongue attached to it to be locked in the locking position.
  • the spring can be designed as a leaf spring which is provided with at least one locking part which projects approximately at right angles.
  • the spring designed as a leaf spring is arranged in a groove in at least one of the key surfaces of the lock insert, as a result of which there are no changes to the key because when it is put on of the key, the spring designed as a leaf spring is pressed back into the groove arranged in the key surface of the lock insert.
  • the recess in the housing cooperating with the locking part is preferably designed as an axial groove formed in the inner bore of the housing, because such an axial groove can be produced particularly easily.
  • the housing is produced by injection molding.
  • the spring is designed as a hat-shaped leaf spring with a central fastening part, two adjoining spring parts and two locking parts pointing in opposite directions, each molded onto the end of a spring part.
  • the lock insert it is possible to fix the lock insert not only in the locking position, but in several defined positions, in that the housing is provided with a plurality of recesses which hold the lock insert in a predetermined position. Such a determination is preferably made not only in the locked position of the lock insert, but also in its open position.
  • these can be arranged in radial grooves of the lock insert, which also results in the locking parts also being guided in order to increase functional reliability.
  • the invention proposes to produce the spring as a leaf spring made of spring steel, the spring parts of which are each arranged in a groove in two opposing key surfaces of the front end of the lock insert, which is designed as an external square.
  • the invention results in a rotary bolt, the lock insert of which is positively fixed in the locking position and possibly further positions by the simplest means, namely automatically when the key is removed; this form-fitting determination is automatically canceled when the appropriate key is placed on the key surfaces of the lock insert.
  • the rotary latch shown in a longitudinal section in Fig. 1 consists of a housing 1 and a lock insert 2.
  • the housing 1 is designed as a substantially cylindrical socket with a flange-like edge 11 which bears against the outside of the door or flap when the housing 1 has been inserted into a corresponding recess in the door or flap.
  • a thread is formed on the lateral surface 12 of the housing 1, onto which a nut (not shown in the drawing) can be screwed in order to be able to fasten the housing 1 to the door leaf or to the flap.
  • the lock insert 2 is rotatable in a stepped bore of the housing 1, but is axially immovable. At its rear end protruding from the rear of the housing 1, the lock insert 2 is provided with a square 21 onto which a locking element, in the exemplary embodiment a locking tongue 3, can be placed. This locking tongue 3 is fastened to the lock insert 2 by means of a screw 4, which at the same time ensures that the lock insert 2 cannot emerge from the housing 1 in the axial direction.
  • the lock insert 2 is provided with key surfaces 22, onto which a key 5 which can be seen in FIG. 3 can be placed.
  • the key surfaces 22 are designed in the manner of a square.
  • two opposing key surfaces 22 are provided with a spring, which is designed as a hat-shaped leaf spring 6 according to FIGS. 7 and 8.
  • This leaf spring 6 comprises a central fastening part 61, two adjoining spring parts 62 and two locking parts 63 pointing in opposite directions, each formed on the end of a spring part 62.
  • the leaf spring 6 is fastened by means of a notched nail 7 to the end face of the key surfaces 22 having the end of the lock insert 2 attached.
  • axially extending grooves 23 for the spring parts 62 of the leaf spring 6 are formed in the two opposing key surfaces 22 of the lock insert 2. Radial grooves 24 adjoin each of these grooves 23, in which the locking parts 63 of the leaf spring 6 are guided when the leaf spring 6 has been fastened to the lock insert 2 by means of the notch nail 7.
  • the front ends of the locking parts 63 of the leaf spring 6 protrude beyond the cylindrical circumference of the lock insert 2 in the normal position. They each engage in an axial groove 13, which are formed in the inner bore of the housing 1.
  • the inner bore of the housing 1 is provided with four such axial grooves 13, which are each offset by 90 ° to one another, as shown in FIGS. 2 and 4.
  • the lock insert 2 Due to the ends of the locking parts 63 engaging in two opposite axial grooves 13, the lock insert 2 is fixed non-rotatably in the housing 1 in the locking position.
  • the suitable key 5 on the key surfaces 22 to put the lock insert 2.
  • the spring parts 62 of the leaf spring 6 are pressed into the grooves 23 of the key surfaces 22; at the same time, the front ends of the locking parts 63 are withdrawn from the axial grooves 13 of the housing 1, so that the lock insert 2 can be easily rotated in the housing 1.
  • the lock insert 2 is thus fixed in a vibration-proof manner not only in the locking position but also in the open position.
