Definitions

  • the present invention relates to a high safety lock for overhead doors, gates and the like.
  • Prior locks for overhead or swinging doors, gates or the like are made in several different types depending on the application type and/or on the type of gate or door to be provided with said locks.
  • Both the above mentioned lock types are provided with driving means, usually controlled from outside by a lock key and with a manually operated pin in the inside of the lock, which pin will enable or prevent the operation of the handle by means of which the lock is opened or closed.
  • the lock handle is latched, in the closure condition of the lock, so that said handle can not turn, being engaged by a tooth element or by a mechanical gear assembly thereon the handle, on the contrary, operates, as it is disengaged, by means of the key or of the pawl element, which can be accessed from the inside side of the door.
  • the aim of the present invention is to overcome the above mentioned problem, by providing a high safety lock, which can not be tampered even if, with the lock in its closing condition, the handle is subjected to a comparatively effort.
  • a main object of the present invention is to provide such a lock which, while having a very simple construction, is very safe in operation and can be provided either with a single or with a plurality of lock bolts, depending on requirements, and which can be made at a very competitive cost, much smaller than that of prior commercially available locks.
  • a high safety lock for overhead doors, gates and the like comprising a box-like construction supporting a rotatable handle and at least a sliding bolt, projecting from said box-like construction, characterized in that said lock comprises means for connecting the handle to the bolt, as well as means for switching off said connecting means, which can be controllably driven in order to cause said bolt to slide as the handle is turned, during the opening or closing operation of the lock, and in order to cause the handle to idly turn, upon closing of the lock.
  • the lock according to the present invention which has been generally indicated by the reference number 1, comprises a box-like construction 2, rotatably supporting, about an axis 3a, a driving handle 3 and at least a lock bolt 4, projecting from the box-like construction 2.
  • connecting means Between the handle 3 and the bolts are arranged connecting means, and are moreover provided means for switching off or deactuating said connecting means.
  • the switching off means can be controllably driven so as to cause the lock bolt or bolts to slide, as the handle 3 is turned, during the opening or closing operation of the lock, and so as to cause the handle 3 to idly turn, upon closing the lock, so as to prevent any tampering attempts to operate the lock bolts by forcing the handle 3.
  • the means connecting the handle 3 to the mentioned bolts comprise a nose element 8, supported by the box-like construction 2, so as to rotate about its axis, which substantially coincides with the axis 3a of the handle 3.
  • the nose element 8 is centrally traversed by a polygonal cross-section hole 9, provided for receiving the square-cross-section shaft connecting the portion of the handle arranged outside the door with portion thereof arranged inside the door.
  • the connecting means comprise moreover a cam disc 10, which is provided with a central hole 11 therethrough said nose element 8 is caused to pass.
  • cam disc 10 is peripherally provided with a plurality of hollows 12, therewithin are engaged pins 13, rigid with said bolts 4, 5, 6 and 7, so that a rotation of the cam disc 10 will cause the bolts to slide inwardly or outwardly of the box-like construction 2.
  • the connecting means comprise furthermore a clutch-in device, which is arranged between the nose element 8 and the cam disc 10, and which can be operated both for coupling, during the rotary movement, the nose or noix element 8 to the cam disc 10, and for disengaging, in the rotary movement, these two elements.
  • a clutch-in device which is arranged between the nose element 8 and the cam disc 10, and which can be operated both for coupling, during the rotary movement, the nose or noix element 8 to the cam disc 10, and for disengaging, in the rotary movement, these two elements.
  • the clutch-in device comprises a sleeve 14 which coaxially extends about the nose element 8 and is rigid with the latter in the rotary movement about the axis 3a, being able of sliding in a direction parallel to the mentioned axis 3a.
  • the sleeve 14 is provided, at the end portion thereof facing the cam disc 10, with teeth 15 which can be engaged or disengaged by causing said sleeve 14 to axially translate with respect to seats or recesses 16 as provided on the cam disc 10.
  • the switching-off or disengaging means comprise a slide 17 which is slidably supported, along a cross direction of the axis 3a, by the mentioned box-like construction 2.
  • the slide 17 engages in slots 18, provided on the outer shell of the sleeve 14, and engages, by a portion 19 thereof, with a slanted surface or plane 20, constituted by a tab 21 of the mentioned box-like construction 2, said tab being inwardly bent.
  • This displacement is counter-biassed by a blade spring 22, arranged between the box-like construction 2 and the sleeve 14, and operating on the sleeve 14 so as to cause the teeth 15 to engage with the recesses 16.
  • the displacement of the slide 17 transversely of the axis 3a is obtained by a key device 23, including a cam element 24 which can turn under the action of the key of the device 23, operating against a shoulder 25 of the slide 17.
  • the slide 17 can also be driven or displaced by manually driving a pawl 26, which is affixed to the slide 17 and which projects, through a suitable hole 27, from the side of the box-like construction 2 which will face the inside of the room closed by the door.
  • the lock according to the present invention is moreover provided with a further spring 29 which has an end portion thereof affixed inside the box-like construction 2 and which operates, by the other end portion thereof, on the cam disc 10 so as to provide a snap type of effect, as the cam disc 10 is brought to the position thereof actuating the closure of the lock.
  • the hollows 12 are laterally provided with a recess 30, which will cause the bolts 4, 5, 6 and 7 to be locked in their closing position, so as to allow said bolts to be moved in an opposite direction exclusively by rotating the cam disc 10.
  • the nose or noix element 8 and, accordingly, the door handle 3, can turn in an idle manner, without affecting the cam disc 10.
  • This disabling operation of the lock can be indifferently performed either with the bolts in their engaged condition or with the bolts in their disengaged condition.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
