Definitions

  • the present invention relates to a washer for spring latch lock handles, including a return spring.
  • the handles operating spring latch locks are conventionally provided with a flexure coil spring, which is urged so as to cause the lock handle to return to its starting position upon operating the lock.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a washer for spring latch lock handles directly including a spring resiliently restraining the rotary movement of the handle.
  • a main object of the present invention is to provide such a washer for spring latch lock handles which is very simple construction-wise and very reliable in operation.
  • Another object of the present invention is to provide such a washer which can be used both for clock-wise rotary handles and for anti-clock-wise rotary handles, that is adapted to be indifferently assembled either as a so-called right washer or a so-called left washer.
  • a washer for spring latch lock handles characterized in that said washer comprises a disc member including a central hole and a plurality of perimetrical holes, said disc member coaxially supporting thereon a steel spring, said steel spring having one end thereof outwardly bent and another end thereof inwardly bent, said spring cooperating with a restraining disc-like element at a central portion whereof there is formed a square hole mating with pin means associated with hub means included in a said handle.
  • the spring and disc-like element are restrained on the disc member by a restraining annular structure having a central raised portion.
  • the washer for spring latch lock handles comprises a disc member 1 including a central hole 2 and a plurality of perimetrical holes 3, as well as a plurality of perimetrical tongues 4.
  • a coil spring 5 provided with end portions 6 one of which is outwardly bent and the other of which is inwardly bent, so as to not interfere against the adjoing coil turn.
  • a disc-like element 7 having a recessed central portion including a square cross-section hole 8.
  • This recessed central portion is provided with a perimetrical cut-out 9, therein there is engaged the radially bent inner end portion of the above mentioned spring.
  • annular structure 10 On the assembly formed by the spring and dis-like element there is mounted an annular structure 10 which, in turn, is provided with a raised central portion on the perimeter of which there is formed an opening 11 for restraining the outer end portion of the spring.
  • the mentioned annular structure is moreover provided with a plurality of perimetrical holes 12 some of which, indicated at 12′, have a raised and threaded edge, and a plurality of perimetrical slots 13 therein can be engaged the tongues 4 of the disc member 1 which tongues will be successively bent on said structure.
  • lugs in particular, will resiliently restrain a screw covering washer 17 which can be provided either with a flat surface (Figure 1) or with a crowned surface ( Figure 3).
  • an anti-friction washer 19 also adapted to operate as a spacer element.
  • Said cage construction holding the mentioned latter, can be affixed to the door by means of throughgoing screws 20 engaging in the threaded portions formed through the annular structure of a cage arranged on the opposite side of the door or, also, by screws 21 directly engaging in the door material.
  • Figure 2 shows a hub member which has been so machined as to directly :over the mentioned holding cage.
  • the constructional features of the spring included in the washer according to the invention will allow the washer to be used on any types of door, included the so-called anti-flame doors.
