  • the electromagnet operates by attracting an externally located armature against the frontal face of the solenoid core.
  • the motion of the armature is transmitted to the detent lever by means of pivoting. bell crank levers or the like.
  • FIG. 1 is a top plan view of the electric door opener according to the invention with the cover removed and showing the detent lever in its position immobilizing the locking lever,
  • FIG. 2 is a top plan view of the same embodiment partially in section, with the locking lever partially removed;
  • FIG. 3 is a top plan view similar to FIG. 1 showing the detent lever in its position allowing movement of the locking lever;
  • FIG. 4 is a top plan view of the same embodiment in its position shown in FIG. 3 and taken as in FIG. 2 along the longitudinal axis of the magnet;
  • FIG. 5 is a cross-sectional view along line 5-5 of FIG. 1 at an enlarged scale
  • FIG. 6 is a fragmentary sectional view along line 6-6 of FIG. 2 at an enlarged scale.
  • a rectangular box-like housing 10 has a pair of spaced support blocks 12 each provided with threaded openings 11 for receiving screws to fixedly hold a closure plate or lid (not shown). Further, the support blocks 12 also carry a shaft 13" for pivotally supporting a swinger latch 14.
  • the cross-sectional configurationof the conventional swinger latch 14 may be best observed in FIG. 5.
  • the rear edge portion of the swinger latch 14 is provided with an integral abutment nose 15 which extends. along a small portion of the length of the swinger latch. By means of the abutment nose 15, the swinger latch 14.
  • a central web portion 42 thereof forms a continuation with a housing web 43 which also serves as an abutment for one of the tenninal positions of the swinger latch 14.
  • the locking lever 18 which extends substantially along the entire length of the housing 10 is pivotally secured at one end by means of a pivot pin 19 extending normal to the base of the housing, 10.
  • the free end of the locking lever 18 extends beyond the terminus of the pivotalshaft 13 into an elongated hollow space 20 formed in the frontal wall portion of the housing 10.
  • the elongated hollow space 20 is disposed transversely to the longitudinal direction of the housing 10 and receives a detent lever 21 which itself is pivotable on a fixed pin 22 disposed in the hollow space 20 and extending through one end of the detent lever 21.
  • the locking lever 18 is urged into its locking position by means of a compression spring 23 which, with one end, engages the wall of the housing 10 and with its other end fits into a depression 25 of the locking lever 18.
  • the detent lever 21 is urged into its locking position by means of a compression spring 24 which, with one end, engages the wall of the housing 10 and with its other end fits into a depression 26 of the detent lever 21. In this locking position a shoulder 27 of the detent lever 21 hooks behind the sharp edge of the free end of the locking lever 18.
  • the locking lever 18 Due to a pivotal motion of the swinger latch 14 during the opening .of the door and the necessary travel of the swinger latch past the door locking bolt, the locking lever 18 is, by virtue of the cooperation between the nose 15 and the oblique recess 17, pivoted into its position shown in FIG. 3.
  • the return spring 23 movesthe locking lever 18 and the latter, through the oblique recess 17 and nose 15, moves the swinger latch 14 into the locking position shown in FIG. 1.
  • the detent lever 21 snaps with its shoulder 27 behind the free end of the locking lever 18 and maintains the latter in its closed position;
  • an electromagnet 28' which, according to the invention, is provided with a solenoid 29 having an axis that extends in the longitudinal direction of the housing 10.
  • the solenoid 29, which takes up a substantial portion of the length of the housing 10, is wound on a spool 30 made of synthetic material. With the solenoid 29 there isasspool 30 against a stationary core 33 situated in the spool 30.
  • the magnet armature 32 centrally holds an actuating pin 35 extending through the core 33 and an intermediate wall 34 of the housing 10.
  • the actuating pin 35 strikes a pin-like extension 36 which extends laterally from the underside of the detent lever 21 and which is disposed in the path of travel of the actuating pin 35.
  • the detent lever 21 is moved into its releasing position against the return spring 24 as illustrated in FIGS. 3 and 4.
  • a return spring 37 formed as a compression spring which engages the base of a frontal recess 38 formed in the armature 32.
  • the frontal recess 38 is so dimensioned that in case of a firm engagement between the armature 32 and the core 33, the compressed return spring 37 may be entirely accommodated therein.
  • terminal strip 39 made of insulating material. It supports terminal screws 40 for receiving electric conductors carrying the energizing current for the solenoid 29.
  • an electrically operable unlatching device for a door opener having (a) an elongated housing, (b) a shaft supporting a swinger latch pivotally held in said housing and projecting therefrom, said swinger latch adapted to assume a closed position, (c) a locking lever pivotable at one end and disposed longitudinally in said housing, said locking lever cooperating with said swinger latch and adapted to assume a locking position in which it locks said swinger latch in the closed position thereof, (d) a detent lever pivotable at one end and disposed in said housing, said detent lever cooperating with said locking lever and adapted to assume an operative position in which it immobilizes said locking lever in its locking position and an inoperative or releasing position in which it permits said locking lever to move freely and (e) an electromagnet having an axis disposed in said housing with its axis extending longitudinally of said housing and operatively connected with said detent lever for moving the latter, the improvement comprising A. a single flat solenoid forming part of
  • said armature includes a frontal recess oriented towards said core and receiving said return spring in its totality when in a compressed state during engagement of said armature with said core.
