Definitions

  • the invention relates to a fitting according to the preamble of the main claim.
  • the additional lock being designed as a pressure cylinder provided with a locking member.
  • the locking member engages in the locking position of the sliding cover covering the sliding cover in a recess of the base plate and thus secures the locking position of the sliding cover.
  • Such a construction is unfavorable in terms of handling, since the additional lock must be actuated to close the sliding cover.
  • the invention is based on the object of specifying a fitting of the type in question of a lock-safe structure in such a way that its handling is simplified.
  • the blocking step is formed by a blocking opening located on the underside of the sliding cover.
  • the spring-loaded locking member enters the locking opening when the sliding cover is closed, the wall area of which forms the locking step.
  • an additional lock-actuable, sliding cover-side release member is provided, which can be displaced into the blocking opening for acting on the locking member in the withdrawal position releasing the sliding cover.
  • This training has the advantage that the additional lock is relieved of locking forces. There is therefore a fitting of increased security value.
  • the additional lock is used exclusively to control the release member in order to move the locking member of the base plate which is spring-loaded in the forward position into the withdrawn position by means of the same in the closed position of the sliding cover. In this way, the locking member is brought out of engagement with the locking opening located on the underside of the sliding cover, which allows the subsequent displacement of the sliding cover into the open position.
  • the locking element guided on the base plate side and spring-loaded in the forward position takes up the locking forces, additional locks of less dimension can be inserted be set.
  • Magnetic locks can also be provided with advantage.
  • the locking element itself can be designed in such a way that, in contrast to known additional locks, it can be subjected to higher loads.
  • the additional lock has a locking hook which is provided with an inclined bevel in the closing direction of the sliding cover and can be folded over by key actuation. This also ensures easy handling.
  • the erected locking hook presses down the spring-loaded locking element with its ramp and closes the sliding cover and runs over it. The locking element springs back after being run over and thus gets into the rear grip of the locking hook. An additional lock actuation is not necessary for this. If the sliding cover is to be moved to the open position, the locking hook is flipped over by key actuation, so that it is guided past the spring-loaded locking element by moving the sliding cover.
  • the locking element fulfills a double function in connection with the stop located on the underside of the sliding cover. When the sliding cover is moved, this limits the opening path in front of the locking element on the base plate side.
  • a trouble-free locking function is ensured in that the locking member is mounted as a displaceably mounted in a stepped recess in the base plate, is formed with a locking pin provided opposite the locking end of the collar.
  • the ring collar serves to limit the forward position of the locking pin, in that it is supported on the step of the recess.
  • the front load on the locking pin or the locking member is provided on the end of the locking pin on the ring collar-side end of the compression spring, which is supported at the other end by the screwed screw plug in the recess.
  • the threaded plug is guided in the recess so that it does not twist unintentionally. Rather, this requires the attachment of a screwing tool, for example the blade of a screwdriver.
  • the crowned end of the locking pin even allows the sliding cover to be moved into the open position if the locking member has not been pushed back completely by means of the release member which can be actuated by the additional lock.
  • the spherical locking end causes the locking member to be completely displaced into the withdrawal position, namely through the corresponding edge of the locking opening.
  • the release member is designed as a plunger passing through a channel opening into the bottom of the blocking opening.
  • the additional lock is designed as a magnetic lock, the rear pushing out this plunger having. If the corresponding magnetic key is assigned to the magnetic lock, it can be shifted inward against the load of a compression spring combined with simultaneous entrainment of the plunger and actuation of the locking member.
  • the fitting 1 illustrated in the drawings has an elongated, rectangular base plate 2 in plan. In the upper region, this carries a handle 3.
  • the lower region 4 of the base plate 2 is stepped and takes up a sliding cover 5 guided in the longitudinal direction of the base plate 2. Its front surface 6, which extends over a short length of the fitting, is flush with the front surface 7 of the base plate 2.
  • the cross section of the sliding cover 5 is selected so that the side walls 8 of the sliding cover 5 continuously merge into the side surfaces 9 of the base plate 2 with the realization of a transition-free appearance.
  • the fitting 1 essentially has a trapezoidal shape both in the longitudinal and in the cross section.
  • the front surface 6 of the sliding cover 5 is surmounted by a material thickening 10, the side walls 10 'of which merge into the side walls 8.
  • guide grooves 11 are recessed over the entire length of the sliding cover, into which laterally projecting guide webs 12 of the lower region 4 of the base plate 2 are immersed. In this way, it is possible to shift the sliding cover 5 in the longitudinal direction to the base plate 2 and to move it to the separation point T between the base plate 2 and the sliding cover 5.
  • the width of the recess 15 is greater than that of the end 16 of a locking cylinder 17 which projects into it a receiving opening 18 of the lower area 4 of the base plate 2 penetrating profile cylinder. If the sliding cover 5 is in its closed position, it overlaps the locking cylinder 17 and does not permit the key associated with the locking cylinder 17 to be inserted.
  • a step-like recess 19 is provided on a side lying beyond its longitudinal center line.
  • the latter is composed of a section 19 ⁇ of larger cross section facing the stop surface of the fitting and a section 19 ⁇ of smaller cross section facing the underside 13 of the sliding cover.
  • the length of section 19 ⁇ corresponds to a multiple of the length of section 19 ⁇ .
  • a step 19 ′′′ is formed by the two sections.
  • a locking member 20 is guided in the recess 19.
  • the latter is designed as a locking pin which is provided with an annular collar 22 opposite the smaller cross-section locking end 21 and which is loaded in the forward position by a compression spring 23.
  • the compression spring 23 is supported on the one hand on the end face of the locking member 20 on the ring collar side and on the other hand on a threaded plug 24 screwed into the section 19 ⁇ of the recess 19.
  • the annular collar 22 of the locking member 20 lies in the forward position at the step 19 ′′′ of the recess 19 in such a way that the locking end 21 projects beyond the lower region of the base plate 2 and engages in a locking opening 25 extending from the underside 13 of the sliding cover 5.
  • a channel 26 extends transversely to the stop plane of the fitting.
  • a release member 27 designed as a plunger is guided.
  • the latter forms a thickened head 28 provided with a transverse slot, which is larger in cross-section than the channel 26 and in the blocking opening 25 is inserted.
  • the thickened head 28 extends to the locking end 21 of the locking member 20.
  • the shaft end 29 of the plunger-like release member 27 opposite the head 28 is screwed into the housing 30 of an additional lock designed as a magnetic lock 31.
  • the magnetic lock 31 has a circular cross section and is inserted into a cross-sectionally adapted cup-shaped depression 32 of the material thickening 10 of the sliding cover 5 in such a way that in its locked position it closes with the corresponding front surface 10Type of the material thickening 10, see FIG. 5.
  • a conical compression spring 33 loads the magnetic lock housing 30 in the outward direction.
  • This compression spring 33 is supported with its larger diameter turn on the bottom 32 ⁇ of the pot-shaped recess 32, while the smaller diameter turn acts on the facing end face of the housing 30.
  • the housing 30 is guided by a pin 34 arranged centrally to the recess 32. The latter passes through the compression spring 33 and is fixed on the sliding cover 5 by means of a screw 35.
  • the magnetic lock 31 has an embedding recess 36 for a magnetic key 37.
  • a stop 38 which interacts with the locking member 20 and limits the opening path of the sliding cover, is provided on the underside of the sliding cover 13. The latter extends at right angles to the shift plane. Between the stop 38 and the locking opening 25 there is an upward slope 39, which starts from the stop 38 in the direction of the locking opening 25 and rises to the underside level, with which the locking member 20 cooperates.
  • the base plate 2 carries a ball catch 40.
  • the latter is composed of a compression spring 41 and a ball 42. Both are accommodated in a sleeve 43 inserted into the base plate 4 and are held by a screw 44.
  • the bottom of the sleeve 13 facing is slightly caulked so that the ball 42 can not leave the sleeve, but presses against the underside 13 and holds the sliding cover 5 frictionally. A shift of the cover 5 must therefore always be deliberate.
  • the latter need only be pushed in the upward direction.
  • the spring-loaded locking member 20 is brought up to the underside level of the sliding cover via the run-up slope 39, so that in the final phase of the closure movement the spring-loaded locking member 20 can dip into the locking opening 25 with its locking end 21, blocking movement of the sliding cover 5.
