Definitions

  • the present invention relates to an electric lock provided with an opening handle which acts directly on the spring latch.
  • electric locks are provided with a spring latch and with a reloading piston provided with a tang being guided in a slot of an element which can slide inside the lock casing and can be blocked by means of a ratchet system controlled by an electromagnet.
  • the reloading piston is coupled to the sliding element by means of a spring which remains compressed when the reloading piston, in door closure position, abuts against the doorjamb, whereas the ratchet system keeps the sliding element blocked.
  • the spring acts on the sliding element which, in its movement, pulls the spring latch into the casing, allowing to open the door.
  • the preamble of claim 1 is known from FR-A-1 484 810 which describes an electric lock comprising a casing provided with a front wall, a spring latch which is guided in an opening of said front wall, said spring latch comprising a stem, spring means which act on said spring latch to bring it into a position in which it protrudes from the front wall, a slider which is slideably guided in said casing parallel to said stem, means for blocking said slider, said means being controlled by an electromagnet between a position for blocking said slider and a position for releasing it, a reloading piston which is slideably guided parallel to said slider in an opening in said front wall, said piston being elastically connected to said slider by means of a spring, said spring being stronger than the spring means of the spring latch, said spring latch being provided with engagement means for said slider, and an element rigidly coupled to said spring latch.
  • the technical aim of the present invention is a general improvement of such a lock, and in particular improvement relating to the manufacturing, versability and reliability of the lock.
  • the numeral 1 generally designates the lock casing, which comprises a back wall 2 around which a peripheral wall extends; said peripheral wall is composed of an upper wall 3, a lower wall 4, a front wall 5 and a rear wall 6.
  • the numeral 7 designates the closure cover of the casing, which is fixed by means of screws which engage in threaded bushes 9a, 9b, 9c, 9d which are rigidly coupled to the back wall 2.
  • the reloading piston 12 has a cylindrical stem 13, one end of which engages a sliding element 14, hereinafter termed slider.
  • Said slider 14 is constituted by an L-shaped strip which has one portion 15 adjacent to the upper wall 3 and the other portion 16 normal to said wall 3.
  • the end of the stem 13 is guided in a hole of the portion 16 and is provided with a ring 17 which is meant to abut on the portion 16 so as to act as a shoulder.
  • a collar 18 is formed on the stem 13 and acts as rest for an end of a spring 19 which is fitted on the stem 13; the opposite end of said spring 19 abuts against the portion 16 of the slider 14.
  • the portion 15 of the slider is guided along the wall 3 of the casing by a pin 20 which slides in a slot 21 of the portion 15; the portion 15 is furthermore provided, at the end of the edge adjacent to the back wall 2, with a tooth 22 which slides on the back wall 2.
  • the tooth 22 is suitable to engage a notch 23 formed on the edge of a pawl 24 which is articulated about a pivot 25 which protrudes from the back wall 2.
  • the pawl 24 can oscillate between a position which blocks the slider 14, which occurs when the tooth 22 engages the notch 23 (the position shown in the figure), and a position for the release of the slider 14, which occurs when the pawl 24 is turned by an angle at which the tooth 22 disengages the notch 23 to allow the portion 15 to slide toward the rear wall 6.
  • the pawl 24 is retained in the blocking position by a lever 26 which is pivoted in a rocker-like manner on a pivot 27 and is subjected to the action of an electromagnet 28 installed in the casing 1.
  • the electromagnet 28 is provided with a core 29 which is actuated outward by an internal spring, so that it is in contact with the lower arm 30 of the lever 26.
  • the core 29 acts, by virtue of the internal spring, on the lower arm 30 of the lever 26, so as to make the upper arm 31 oscillate into abutment against the bush 9b in the position for retaining the pawl 24.
  • the spring latch 11 is also provided with a stem 32 which is guided through a plate which is blocked between the back wall 2 and the cover 7 of the casing and constitutes a fixed stroke limiter 33.
  • the end of the stem 32 is slideably guided through the portion 16 of the slider, and a lug 35 is coupled to said end by means of a ring 34; said lug is folded at right angles to the back wall 2 and belongs to a bar which forms an element (36) which is rigidly coupled to the stem 32 and which extends next to the side 15 of the slider 14.
  • a slot 37 is formed in the bar parallel to the portion 15 of the slider 14 and is engaged by the pivot 25, which thus keeps the bar guided.
  • a collar 38 is formed on the stem 32, and an end of a spring 39 rests against it; the spring 39 is fitted on the stem 32, and its opposite end rests against the plate.
  • the spring 39 is less rigid than the spring 19 and keeps the spring latch 11 in a position in which it protrudes from the front wall; this position is defined by the abutment of the lug 35 against the plate with the interposition of the portion 16, which remains clamped between the plate and the lug 35.
  • the end of the bar which is opposite to the lug 35 has a wing 40 which is also folded at right angles to the back wall 2 and on which a lever 41 can act; said lever 41 is radially coupled to the hub 42, to which the handle for manual actuation of the lock is rotationally coupled.
  • the bar 36 is used to operatively connect the lever 41 to the stem 32 of the spring latch.
  • the hub 42 is rotatably supported in circular seats of the back wall 2 and of the cover 7 of the casing, and is provided with a square hole 43 in which the square pivot of the handle engages with a side fit.
  • the hub 42 is provided with two lugs 44, 45 which are arranged diametrically.
  • a strut 46 acts on the lug 44; it is loosely guided in the bush 9c and actuated by a spring 47 which acts between said bush 9c and a shoulder 48 of the strut 46.
  • the hub 42 is kept in an angular position defined by the abutment of the lug 45 against the bush 9d; in this position, the lever 41 is disengaged from the wing 40.
  • the spring latch 11 In the door closure position, the spring latch 11 is engaged in the related selvage and thus protrudes from the front wall 5. At the same time, the piston 12 abuts against the doorjamb and is arranged inside the casing. Since the electromagnet 28 is not energized, the core 29 pushes the lever 26 so that it abuts against the bush 9b, so as to prevent the oscillation of the pawl 24 and block the sliding of the slider 14. As a consequence of this, during door closure, when the piston 12 retracts into the casing, the stem 13 slides with respect to the portion 16 of the slider and the spring 19 is compressed.
  • the electric lock according to the invention perfectly achieves the intended aim.
  • the positive action applied with the handle furthermore allows to compensate for the force applied by the spring 19 during opening, which may not be sufficient due to increases in internal friction.
