Definitions

  • Lock With locking function to be released by inserting a key card that is partially m & q-netized
  • the invention relates to a lock according to the preamble of claim 1.
  • Sections which engage pawls articulated at the sides of the slide The control of these takes place via the facing broad area of the key card when the same is inserted.
  • the pawl is removed from the abutment, so that the return spring acting on the slide can take effect and thereby disengage the pawls from the resilient sections. Due to the slide displacement, locking parts are in or out
  • 2S is that e.g. B. the bolt of the mortise lock is totally pre-closed or totally closed is connected with the safety-related intermediate positions.
  • the forced control is achieved by an arm which is articulated in the lock housing and is controlled transversely to the slide movement and which engages in a form-fitting manner on the coupling sleeve. During the advance of the slide, the slide moves
  • the key card is bound by the form-fitting holder.
  • the form-fit holder is formed by a pin which is mounted in the slide and automatically moves into a hole in the key card by the slide movement. The corresponding manufacturing effort for this additional function can therefore be kept extremely low. Only a corresponding pin has to be accommodated in the slide. However, the key card must form the hole at the corresponding position. This means that after inserting the key card into the key card slot of the lock, the pin and the hole are aligned.
  • the area of the slide facing the mouth area of the key card insertion slot is particularly suitable for accommodating the pin. Moreover, through the pen
  • 35 another closing variation can be achieved. This can happen by the position and / or shape of the pen so that it can be used as a variation code pen. In practice, this means that the slide can only be advanced with the key card, which has the correspondingly designed hole at the correct position. According to a variant, the forced control can also be such that it already blocks displacement of the slide in the direction of insertion of the key card when the position H between the actuating handle and the coupling sleeve is not in conformity with the coupling.
  • Shifting the slide by means of the key card is therefore only possible if the coupling sleeve is in its correct starting position.
  • Another possibility of creating a lock blocking the return of the slide is characterized in that the lock is designed by an extension of the slide which has a key projection which, when the locking part is in the correct position, is moved back by moving the slide immersed in a recess of the closing part t. If the latter takes an intermediate position, the slide cannot move back completely. Therefore, the key card cannot be removed due to the form-fitting holder. The user is made aware of the fact that the actuating handle and thus 5 the locking part are to be brought into the correct position.
  • the extension In terms of construction and loading, it is favorable to design the extension as a bracket and to arrange the tactile projection in the apex area of the bracket opening receiving the locking part. This results in central force transmissions. If the slide is equipped with a second key projection for entry into a further recess of the closing part when the slide is advanced, then an insertion lock is achieved through it. Moving the slide forward using the 5 key card accordingly also sets the moderate basic position of the locking part in advance.
  • a further version is characterized in that the lock is formed by a lever adjacent to the slide, which has a key projection which, when the locking part is in the correct position and the slide is displaced, plunges into a recess in the locking part and which is one of the Key card-controlled supplementary tumbler of the slide to escape from the key card slot.
