Definitions

  • the invention relates to an electrically controllable locker with a housing, a bolt mounted in this housing, a stationary electromagnet and one, with a magnetic armature provided control lever through a dome of the bolt is noted and which affects a locking device.
  • Such a lock has become known from EP 0228027.
  • Two relatively complicated control and locking levers are pivotally mounted on a common pin and coupled by a tension spring.
  • the control lever has a tour pin channel, the locking lever has a magnetic armature.
  • Control and locking levers are located in the lock housing under the main latch, while the electromagnet assigned to the armature is accommodated in a rear recess in the lock housing.
  • This design not only requires expensive casting tools for the housing provided with front and rear recesses, but also tight tolerances for the manufacture and adjustment of the lever mechanism mentioned.
  • the object of the invention is to simplify the manufacture of locks controlled by holding magnet technology and at the same time to increase their reliability. It is also an object of the invention to design the housing, bolt and magnetic mechanism so that, depending on the task, a tumbler lock or a lock cylinder can be inserted into the housing as a second lock.
  • a cross slide serves as a locking device, which is deflected against the force of a spring, one end of the control lever being mounted on the cross slide and a control pin of the bolt engaging a control slope of the control lever.
  • the cross slide, the control lever and the electromagnet are mounted on the bottom of the box-shaped housing.
  • the bolt on which either a tumbler package or a locking cylinder is placed.
  • the handle which is only electrically controlled, uses a handle with a straw and double-bit. For these three embodiments, only two different lock ceilings are required, namely one with a double-bit keyhole and one with a pre-shaped recess for the lock cylinder.
  • Fig. 1 designates the box-shaped housing from which the latch 2 protrudes.
  • an electromagnet 3 is fastened, against which an armature 4 designed as a triangle bears.
  • This anchor is mounted on a control lever 5.
  • This lever rests with its left end on a cross slide 6, the blocking block 6a blocks or releases the bolt 2.
  • a swivel 7 which can be pivoted about a mandrel 8 fixed to the housing.
  • a nose 7a of the vertebra 7 takes the bolt 2 with it.
  • the vortex 7 has the task of translating the movement of the key bit or the locking cylinder cam into a larger path.
  • the lock housing 1 has three integrally formed hollow columns 1a, 1b, 1c, which are used to fasten the lock.
  • a circuit board 9 is held, which carries a microswitch 10 in addition to electronic components. Its function will be explained later.
  • a second microswitch is mounted on the circuit board 9, the Touch lever rests on the door surface through a hole in the lock ceiling. If one Burglars attempt to force the lock away by this Microswitch alarm triggered.
  • Fig. 2 shows an opening attempt without energization. If the bar 2 is moved to the right by a few millimeters, its control pin 2a pushes the right end of the control lever 5 upwards. The armature 4 lifts off the yoke of the electromagnet 3. The interrogation movement of the bolt 2 is limited in that a locking edge on its underside abuts the locking block 6a of the cross slide 6.
  • the quite deep housing 1 is shown three-dimensionally.
  • the locking head which emerges from the rectangular opening 1d, is guided between the hollow columns 1a and 1b.
  • the main bearing pin 11 guides the tumbler package 12 and other parts.
  • Two webs 1e, 1f are formed on the bottom of the housing and guide the cross slide 6.
  • Its locking block 6a is normally under the bolt 2.
  • a mandrel 6b protrudes into an opening 5a of the control lever 5.
  • the control mandrel 2a of the bolt 2 moves the control lever 5 via a control slope 5b.
  • the vortex 7, a special tumbler 13 and the tumbler package 12 is shown.
  • a lock cover 14 has a double-bit keyhole 14a in addition to the fastening holes.
  • a latch 15 is mounted in addition to the bolt 2, which prevents in a known manner that the bolt 2 can be extended and the key removed when the door is not in the frame.
  • the latch 15 deviates to the right and displaces a locking block 16 mounted on the housing base, which releases the bolt 2 via a control edge 16a.
  • Fig. 4 shows the lock variant in the most common form. The customer or tenant opens the compartment with his double-bit key after a supervisor has checked the access authorization and released the lock with an opening impulse.
  • Fig. 5 shows another design, in which the parts 1, 2, 5, 6, 7, 15, 16 and 17 correspond completely to Fig. 4 .
  • a blanket 18 is placed, which carries a locking cylinder 19.
  • This lock cylinder rests in a cast-on cylindrical bearing flange 18a of the ceiling.
  • the closing cam of the cylinder 19 is designated 19a.
  • Fig. 6 shows a variant with only one locking system.
  • mechanical closures are dispensed with for cost reasons and the opening is controlled via an input keyboard or a code card.
  • the cover 14 corresponds to that of FIG. 4.
  • a handle 20 with a straw 21 and double-bit 21a is used.
  • a leg spring 22 stabilizes the position of the parts. All other components can be stored pre-assembled so that you can complete any number of the desired lock version in the shortest possible time.
  • Fig. 7 shows a design in which the release current is supplied via the head 2b of the bolt 2.
  • a contact pin is installed in the locking head 2b, which is connected to the printed circuit board 9 ( FIG. 1 ) via a line 23.
  • a second connection is to the mass of the latch or metal housing. The power is then supplied via contact springs in the frame of the cabinet. This has the advantage that no release cable susceptible to faults has to be led from the door to the frame.
  • FIG. 8 the current is supplied in the same way as in FIG. 7. In all other details, the structure corresponds to FIG. 5.
  • the control lever 5 is shown from the side and from above.
  • a mandrel 5c can be seen which receives the armature 4.
  • a resilient hook 5d Behind the mandrel 5c is a resilient hook 5d, which yields when the anchor 4 is inserted and prevents this anchor from falling out.
  • 10c shows the control lever in perspective from above, FIG. 10d from below. It can be seen that a slot 5e is provided under the hook 5d, which ensures the elastic deformability of the hook 5d.
  • the part 5 is injection molded from an impact-resistant thermoplastic, so that it is very accurate and inexpensive to manufacture. Without the use of a spring washer or the like, the anchor 4 is easily installed and held securely.
  • the locker described is ideally suited for lockers at banks. Hotels and leisure facilities to be used in a variety of ways. With three basic versions and the power supply via the bolt head or a housing cable, you get six different end products with a minimum of tools so that you can respond quickly to different customer requests with the smallest of stocks. If you include the option of a microswitch as a lifting contact, you get twelve different lock types with just a few basic modules. For the production process and the storage, it is important that the key guide mandrel is not cast in or inserted immediately into the housing, because it is not required for the variants according to FIGS. 5, 6 and 9. Rather, this mandrel is pressed in only during the final assembly of the variants according to FIGS. 4 and 7.
