Definitions

  • Glass breakage is well known: the action organ, in this case a push button, is advanced by a glass which must be broken before it can be triggered.
  • the subject of the present invention is an interlocking device of the "glass breaking" type, avoiding these drawbacks.
  • the transition from the standby position to the alarm position is effected by a voluntary push or by a shock, for example using a hammer; upon resetting, the passage from the alarm position to the standby position can be done directly, using a specialized tool, or by disassembly and reassembly of the assembly, using a tool usual, for example a screwdriver.
  • the passage of the action member from the standby position to the position of alarm occurs without any real glass breakage or projection of splinters, and the possible resetting speed allows full-scale tests, the brevity of the trigger cannot in this case be confused with a real trigger.
  • the latching device comprises a housing 1 serving as a housing for a push button 2.
  • a cover 3 which is in the form of a frame, closes the housing 1.
  • the cover 3 is removably attached, by screws 10, on the housing 1 and is rectangular; by two of its opposite internal edges, it forms a housing 31, which is in fact constituted by a notch made in its thickness 3.
  • a rectangular plate 4 which is made of elastic material, is forcibly engaged in this housing 31, by a part of its periphery, namely its two corresponding opposite edges; its relative dimensions, between these two opposite edges, are greater than those of the housing 31, so that it cannot take a planar shape and is on the contrary, by elasticity, reversibly deformable between two stable shapes, one corresponding to a standby position, for which it is “convex" towards the outside of the housing 1, the other corresponding to an alarm position, for which it is "convex” to the interior thereof.
  • the plate 4 is "curved" outward from the housing; it is then at a distance from the push button 2 and the latter is in the triggered position or "waiting position".
  • the housing 31 of the frame 3 forms by itself a means of clamping the plate 4, which maintains, as described, the convex shape, either in one direction or in the other.
  • the plate 4 is also elastically deformable in a reversible manner, but its clamping means is formed by a rigid frame 43, distinct from the cover 3.
  • This embodiment makes it possible to accommodate with play l 'plate 4 and frame 43 in the housing 31 of the cover 3, the manufacturing tolerances then being less severe.
  • Two transverse bands 44, 44 ' which form one body with the central band 41, connect the lateral bands 42, 42', forming with them the associated rigid frame 43.
  • the plate 4 is circular in shape and is generally preformed into the shape of a spherical segment; the housing 31 of the cover 3 in which it is engaged by its periphery has an appropriate circular shape.
  • the plate 4 can, if desired, be made of transparent material, synthetic material for example, thus recalling the usual "glass breakage".
  • only a portion of the plate used can be reversibly deformable between two stable forms; for example, with regard to the circular shape illustrated for this plate in FIG. 7, only the central portion of such a plate could be preformed into the shape of a spherical segment, the rest of this plate being otherwise plane.
  • the action member it controls is not necessarily a push button; it could for example be directly an electrical contact.
  • Such an action member can either be attached to the housing which contains it, or be integrated therein.
  • This box meanwhile, can be attached projecting on any support surface, or embedded therein, with for example, according to known methods, a fixing screw or claws.
