Definitions

  • the present invention relates to a highly safe automatically closed lock for overhead or swinging doors, gates or the like.
  • the at present commercially available locks can be substantially classified into two different classes: the locks provided with means for automatically causing the lock bolts to return to their closure position, and the locks in which the two opening and closing operations are performed manually.
  • the latter are provided with a key control unit, in order to allow the door to be opened from outside, and with a manually operated pin in order to allow the lock to be opened from the inside of the door.
  • the driving of the key or pin will either enable or lock the operation of a rotatable handle, by means of which the lock is either opened or closed, i.e. the lock bolts are so driven as to cause said bolts to slide in order to provide the closing or opening operations of the lock.
  • Prior locks of the above mentioned types do not provide satisfactory anti- tampering characteristics, since, by operating on the lock handle, locked or latched in a closure position, by a comparatively high force, it is possible to damage, in a comparatively quick manner, the lock itself, so as to easily unlatching the door.
  • the aim of the present invention is to solve the above mentioned problem, by providing an automatically closed lock, which is specifically designed to efficiently discourage any tampering attempts, tending to unlatch or open the lock by a forced rotary displacement of the handle.
  • a main object of the present invention is to provide such an automatic lock which is very safe and reliable in operation, is very simple construction-wise and can be made at a very reduced cost.
  • a highly safe automatically closed lock for overhead doors, gates or the like comprising a box-like construction, supporting a rotatable handle and at least a slidable bolt, projecting from said box-like construction, coupling means being provided for coupling the handle to the bolt, to allow said bolt to slide for opening the lock, as the handle is turned, characterized in that said lock comprises moreover driving means for automatically driving said bolt in its closing sliding movement, and deactuating means for deactuating said coupling means, said deactuating means being controllably driven in order to idly turn the handle.
  • the lock according to the present invention which has been generally indicated by the reference number 1, comprises a box-like body 2 rotatably supporting, about an axis 3a, a handle 3 and at least a bolt 4 which can be slidably driven and projects from the box-like construction or body 2.
  • the coupling means for coupling the handle 3 to the bolts comprise a nose element or noix 8 which is rotatably supported about its rotary axis, coinciding with the axis 3a, by the box-like body or construction 2 and is axially traversed by a throughgoing hole 9 provided for housing the shaft of the handle.
  • a cam disc 10 which can turn about the axis 3a of the handle and is peripherally provided with a plurality of hollows 11 in which are engaged pins 12 rigid with the bolts, so that a rotary movement of the cam disc 10, about the rotary axis 3a, will cause the bolts to be translated either in a direction or in an opposite direction.
  • a clutch-in device substantially comprising a sleeve 13, which is keyed about the nose element 8 and can axially slide along said nose element 8.
  • the sleeve 13 is provided, at the axial end portion thereof facing the cam disc 10, with teeth 14, provided for engaging in, or disengaging from, upon axially displacing the sleeve 13, seats or recesses 15 formed on the cam disc 10.
  • said recesses 15 are advantageously provided with an arch configuration, of a predetermined amplitude, about said rotary axis 3a, in excess with respect to the size of the tooth elements 14.
  • the lock according to the present invention comprises moreover driving means for automatically driving or operating the bolts, including return resilient means, preferably constituted by a spring 16 which is restrained to the box-like construction 2 and operates by a portion thereof, against a shoulder 17 of the cam disc 10, so as to resiliently counterbias the rotary movement of the cam disc, in the direction thereof causing the opening movement of the bolts, and so as to cause the cam disc 10 to automatically turn in the direction causing the bolts to be slidably closed.
  • return resilient means preferably constituted by a spring 16 which is restrained to the box-like construction 2 and operates by a portion thereof, against a shoulder 17 of the cam disc 10, so as to resiliently counterbias the rotary movement of the cam disc, in the direction thereof causing the opening movement of the bolts, and so as to cause the cam disc 10 to automatically turn in the direction causing the bolts to be slidably closed.
  • a pring 18 can be provided, said spring having an end portion thereof connected to the box-like construction 2 and the other end portion thereof connected to the body of the bolt 6, so as to resiliently counterbias the opening movement of the bolt 6 in order to provide, by a resilient reaction, the closing movement of the bolt 6, by cooperating with the spring 16 affecting the cam disc 10.
  • the lock according to the present invention comprises furthermore, deactuating means for deactuating the coupling means coupling the handle to the cam disc 10, which comprise a slide 20 which can slide along a cross direction of the axis 3a.
  • the slide 20 is provided with a portion 20a connected with a slanted plane 21, constituted by a tab element, or tongue element, 22 of the box-like construction 2, inwardly deflected or bent, so that the translation of the slide 20, transversely of the axis 3a, will also cause a translation in a direction substantially parallel to the mentioned axis.
  • the slide 20 engages with a slot 23 provided on the sleeve 13, so that the slide 20, as it is driven along the axis 3a in a direction, will cause the sleeve 13 to be driven in that direction causing the teeth 14 to disengage from the recesses 15.
  • This displacement of the sleeve 13 will be resiliently counterbiassed by a spring 24, arranged between the sleeve 13 and a wall of the box-like construction 2.
  • the displacement of the slide 20 in the opposite direction, i.e. that direction causing the sleeve 13 to be engaged with the cam disc 10, is resiliently counterbiassed by a spring 25.
  • the displacement of the slide 20, in the direction opposite to the operating direction of the spring 25, i.e. that direction causing the sleeve 13 to be engaged with the cam disc 10, is obtained by a key device 26, which is connected to the box-like construction 2 and being provided with a cam 27 provided for operating, upon rotating a key engaged in the device 26, on the slide 20.
  • a pin 28 affixed to the slide 20 and projecting from the box-like construction through a hole 29.
  • the above mentioned pin 28, in particular, can be manually operated so as to allow the lock to be opened from the inside part of the door.
  • the subject lock operates as follows.
  • the upwardly displacement of the slide 20 can be obtained by manually operating the pin 28 from the inner side of the door.
  • cam disc 10 will be coupled, in its rotary movement about the axis 3a, with the nose or noix element 8 and, accordingly, with the handle 3.
  • the cam disc 10 is turned about the rotary axis 3a thereof, with a consequent sliding movement of the bolts toward the box-like construction 2, i.e. in the opening direction.
  • any tampering operations exerted on the lock by causing the handle 3 to be forcibly turned, will have no effect, since the handle, with the lock in the closing position thereof, will idly turn.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
