Definitions

  • the invention relates to a lock comprising a lock nut for actuating a lock mechanism, a Reduzierhülse for receiving a trigger pin and for transmitting a torque between the pusher pin and the lock nut, the Reduzierhülse consists at least in a partial region of a ferromagnetic material.
  • the lock nut of a lock is rotatably mounted and actuates a lock mechanism, if, for example, by a pusher torque is introduced into the lock mechanism, whereby, for example, a case of the lock is pulled into an associated lock housing so to open a door can by the case held in a closed position.
  • the pusher has a pusher pin which engages positively in a through opening formed by walls opening channel of the lock nut, whereby the introduced via the pusher and the lock nut torque is transmitted to the lock mechanism.
  • a Reduzierhülse is used in a lock nut, the opening channel for receiving the pusher pin is so large, in which a torque transmission from the pusher pin can not be transmitted, since the pusher pin is formed too small, whereby no positive connection between the lock nut and the pusher pin are formed can.
  • the Reduzierhülse overcomes the dimensional difference between such a lock nut and the Drückerstatt, whereby the torque transmission is ensured by the pusher pin on the Reduzierhülse to the lock nut and thus the lock mechanism.
  • Object of the present invention is to provide an inexpensive device in which a torque transmission of the pusher is to ensure and a displacement of the Reduzierhülse during assembly or disassembly of the pusher is to be avoided in the opening channel.
  • At least one magnet for releasably fixing the reducing sleeve is connected to the lock nut such that the magnetic force acts on at least one ferromagnetic portion of the reducing sleeve.
  • Reduzierhülse remains fixed both in the assembly and during disassembly of the pusher in the opening channel of the lock nut.
  • pushers that form no positive connection with the lock nut can ensured by using a Reduzierhülse the transmission of a torque introduced via the pusher in the lock mechanism and excluded a malfunction on the lock.
  • the magnet can be arranged in a recess of the wall of the opening channel of the lock nut.
  • the magnet essentially fills the depression, as a result of which the magnet can be placed in the lock nut in such a way that it can make a direct impact on the reducing sleeve as soon as the reducing sleeve is introduced into the opening channel of the lock nut.
  • the recess may be arranged in the extension of the axial direction of the opening channel in the wall of the opening channel of the lock nut.
  • the wall of the opening channel serves at least partially for the transmission of torque from the lock nut to the lock mechanism.
  • the depression can be arranged centrally or off-center of the opening channel in the extension of the axial direction of the opening channel.
  • the arrangement of the recess within the opening channel is freely selectable, provided that with the there to be inserted magnets in operative connection reducing sleeve is adjusted accordingly to ensure a magnetic effect between the magnet and the Reduzierhülse.
  • the depression in the Be arranged edge region of the opening channel of the lock nut is conceivable to use more than one recess and more than one magnet in the lock nut.
  • the recess may be formed by a blind hole, which can be easily introduced into the lock nut.
  • a blind hole which can be easily introduced into the lock nut.
  • other shapes can be chosen for the recess, provided that the magnet can be used in such forms.
  • the magnet can be arranged non-positively and / or positively and / or cohesively in the recess. This has the effect of keeping open the possibility of arranging the magnet in the recess in different ways, the magnet being able to be fixed detachably or non-detachably in the recess.
  • the magnet can continue to be introduced without tools in the recess, whereby a cost-effective installation of the magnet is effected in the lock nut. It is also possible to retrofit a magnet in a locknut, which can also be done without tools. For this purpose, it is assumed that a locknut used already has a corresponding recess.
  • the reducing sleeve can be a square tube.
  • the Reduzierhülse can be made of a relatively cheap base material.
  • the opening channel has a corresponding corresponding shape in order to be able to receive the reducing sleeve in a form-fitting manner, preferably with little play.
  • the lock nut may consist of a ferromagnetic material at least in the partial area of the recess.
  • the lock nut can thus be made of different materials, provided that the portion of the recess consists of a ferromagnetic material in order to be able to enter into operative connection with the magnet.
  • the lock nut can be completely formed from a ferromagnetic material.
  • the magnet can be fixed by its magnetic force in the recess. If at least the subregion of the recess consists of a ferromagnetic material, it is possible that the magnet can hold itself captive by its magnetic force in the recess, whereby the magnet is fixed there. This is the tool-free installation and retrofitting of the magnet contrary and causes a simple and inexpensive installation of the magnet in the recess of the lock nut.
  • the Reduzierhülse may be formed of a ferromagnetic material at least in a partial area which is to be brought into operative connection with the magnet in order to be able to enter into a magnetic effect with the magnet.
  • the magnet may be a disc magnet.
  • the magnet may have dimensions which have a height of 1 mm to 10 mm and a diameter of 1 mm to 10 mm. It has been found that a magnet with a diameter of 2 mm and a height of 1 mm is already sufficient to hold the reducing sleeve in the lock nut, wherein the distance between the reducing sleeve and the magnet may preferably be 0.005 mm to 0.5 mm. Thus, a magnet of relatively small size can be used. Other shapes of the magnet, such as a rectangular or square magnet are also conceivable.
  • the magnetic force of the magnet can be dimensioned such that the Reduzierhülse remains fixed during assembly or disassembly of the pusher pin with the lock nut in extension of the axial direction of the Reduzierhülse.
  • the wall, in which the recess can be arranged can be formed with a planar or flat surface with at least one interruption.
  • the magnet can be arranged in the recess such that it preferably does not make contact with the reducing sleeve inserted into the opening channel, it being ensured that the magnetic force of the magnet acts on the reducing sleeve and sufficient to the Reduzierhülse also during assembly or disassembly of the pusher fixed in place in the opening channel of the locknut.
  • the magnet may have a magnetic force which, depending on the dimensional configuration of the magnet, is between 0.20 g and 1500 g, preferably between 50 g and 800 g, particularly preferably between 100 g and 500 g is. It has been found that the distance between the magnet and the Reduzierhülse is kept very low in order to use approximately the full magnetic force of the magnet can. Thus, the distance between the Reduzierhülse and the magnet is preferably to be selected in a range of 0.005mm to 0.5mm, wherein the magnetic force of the magnet decreases sharply with increasing distance to the Reduzierhülse.
  • the magnet may be a permanent magnet, preferably a neodymium magnet or a ferrite magnet.
  • the magnet used is preferably a neodymium magnet, which is preferable to a ferrite magnet, if a multiple magnetic force is to be achieved over a ferrite magnet.
  • a ferrite magnet which is less expensive than the neodymium magnet.
  • the reducing sleeve can be arranged at least partially positive fit in the lock nut. This ensures that the torque introduced by the pusher pin is transmitted to the lock nut and thus to the lock mechanism.
  • the continuous opening channel of the lock nut extends in the axial direction of the lock nut through the lock nut.
  • the opening channel is essentially the Reduzierhülse used, the Reduzierhülse is still arranged substantially form-fitting manner in the opening channel.
  • the opening channel is formed from preferably four walls of the lock nut, wherein further forms are conceivable, provided that these forms are suitable for being able to receive the reducing sleeve in a form-fitting manner.
  • Fig. 1 shows a lock 1 in a perspective view, in which a Reduzierhülse 3 is inserted into a lock nut 2.
  • Fig. 2 shows the lock nut 2 with the inserted reducing sleeve 3, which is flush with the frontal plane 8 of the lock nut 2.
  • the Reduzierhülse 3 also closes flush on the non-visible side of the lock nut 2 with the other non-visible frontal plane.
  • the reduction sleeve 3 has a base material Square tube, wherein the Reduzierhülse 3 is inserted substantially positively in the lock nut 2.
  • the reduction sleeve 3 corresponds to walls of the lock nut 2, wherein the walls of the lock nut 2 are interrupted by circular arcs. Via the corresponding walls, the torque introduced by the pusher is transmitted from the reducing sleeve 3 to the lock nut 2.
  • the reducing sleeve 3 terminates flush with the two end planes of the lock nut 2, wherein it is conceivable that the Reduzierhülse 3 has a collar, which is based on one of the two frontal planes of the lock nut 2 in the inserted state. In the event that the Reduzierhülse 3 has a collar, a frontally disposed recess 5 in the lock nut 2 would be conceivable in which the magnet 4 can be arranged, which can make a magnetic effect with the collar of the Reduzierhülse 3.
  • Fig. 3 shows the lock nut 2 with arranged magnet 4 and the Reduzierhülse 3 outside the lock nut 2, in the state before the Reduzierhülse 3 is inserted in the axial direction 6 in the lock nut 2.
  • the lock nut 2 has a through-opening channel 7, which is formed by walls which are interrupted by circular arcs.
  • the reducing sleeve 3 made of a square tube is designed such that it can be inserted in a form-fitting manner with little play in the through-opening channel 7 of the lock nut 2.
  • Fig. 4 shows the lock nut 2, the magnet 4 and the Reduzierhülse 3 in an exploded view.
  • the continuous opening channel 7 of the lock nut 2 has a recess 5, which in an edge region the lock nut 2 and in the region of the circular arc is arranged almost in the middle of the opening width of the through-opening channel 7.

  • Fig. 5 shows the detail view X from the Fig. 4 , in which the lock nut 2 with the recess 5 and the magnet 4 is shown.
  • the recess 5 is formed as a blind hole into which the magnet 4, which is preferably designed as a disc magnet, can be inserted.
  • the magnet can be inserted positively and / or non-positively and / or cohesively into the recess 5. It is also possible that the magnet 4 can be inserted without tools in the recess 5.
  • the lock nut 2 consists of a ferromagnetic material, whereby the magnet 4 is held by its magnetic force after insertion into the recess 5 itself in the recess 5 and is fixed there.
  • the magnetic force of the magnet 4 acts on the consisting of ferromagnetic material Reduzierhülse 3 and fixes them in the lock nut 2, whereby the Reduzierhülse during assembly and disassembly of the pusher in the opening channel 7 of the lock nut 2 remains fixed.
  • a cost-effective device is provided in which a torque transmission of the pusher is ensured in the lock mechanism and a displacement of the Reduzierhülse 3 is prevented during assembly or disassembly of the pusher in the opening channel 7 or from the opening channel 7.
