Definitions

  • the present invention relates to alarm boxes which are found in particular in public places and which are intended to protect warning devices such as rings, emergency telephones, and the like.
  • Patent US-A-2 698 354 describes an alarm device comprising a support for the alarm device, formed of a rectangular plate arranged vertically and a protective cover articulated on the support, which is normally retained, relative to the latter, in the closed position by means of a shear pin but can be opened by breaking, by manual action, of this pin by pivoting about a hinge pin provided at the lower end of the cover.
  • the invention aims to create an alarm box of the aforementioned type which, while being simple in construction and therefore of moderate cost, is produced so that it can be used several times and requires for this purpose replacing a number of parts reduced to a minimum.
  • the invention relates to a box intended to protect an alarm or security device, comprising a support for the alarm device in the form of a rectangular plate arranged vertically and, for the protection of this device, a cover articulated on the support, which is normally retained, relative to the latter, in the closed position by means of a shear pin, but can be opened after rupture, by manual action, of this pin in pivoting about an articulation axis which is constituted by two lugs provided at the lower end of the cover, characterized in that the cover, the lugs of which are engaged in corresponding slides formed on the respective vertical edges of the support, is retained in the closed position, upwards by inserting its upper end edge into a folded edge of the support, and downwards by the shear pin, secured to the support, the breakage of which is us the effect of a shock exerted downwards on the cover causes the two pins to slide down and correspondingly the clearance outside the edge of the upper end edge of the cover, so that the cover can then be opened by pivoting around the two pin
  • the alarm box shown in the drawings mainly comprises a support plate 1 in which are formed by stamping protrusions 2 constituting fastening elements of the support on a wall P by means of screws 3 engaged in holes made in the projections 2.
  • the support plate 1 is rectangular in shape and its two long sides are arranged vertically and have folded edges 4 and 5. Similarly, the short upper side has a folded edge 6 while the short bottom side has an edge in the extension of the surface of the plate.
  • an alarm device which in the present example consists of a push button switch 7 fixed on a sheet metal support 8 and the contacts 9 of which are connected to a conductor 10 connecting the switch to an installation not shown.
  • the support 8 carries a hook 11 intended to receive a key 12.
  • the assembly thus formed is closed by a cover 13 made of unbreakable transparent plastic.
  • the cover 13 has a rectangular base of width slightly less than the distance which separates the folded edges 4 and 5 of the support plate 1. It further comprises in the extension of its small lower side two lugs 14 intended to be engaged in the slides constituted by the folded edges 4 and 5. The small upper side of the cover 13 is intended to be engaged by sliding in the housing defined by the folded edge 6.
  • a projecting housing 15 in which is engaged a shear pin 16 intended to immobilize the cover 13 when its small upper side is engaged under the folded rim 6 of the support plate 1.
  • Plate 1 also carries a reserve 17 of spare pins.
  • the cover 13 is connected to the support plate 1 by a flexible connecting element 19 whose length and point of connection with the support plate are such that the cover, when it is released from the folded rim 6 of the plate support, can rotate around its lugs 14 which are held in the slides formed by the folded edges 4 and 5 of the vertical sides of the support plate 1.
  • the establishment of the cover 13 on the support plate 1 is ensured by sliding the lugs 14 of the cover into the lower part of the slides defined by the folded edges 4 and 5. Then, the base of the cover 13 is applied against the plate and, by an upward sliding movement, the short side of the cover 13 opposite the lugs 14 is engaged under the folded edge 6 of the support plate 1. In this position, the housing for the shear pin is released and a pin 16 is introduced therein which immobilizes the cover 13 in translation relative to the support plate 1. The cover 13 is thus immobilized on the one hand by the folded rim 6 of the support plate; and on the other hand by the shear pin 16.
  • the box shown in FIG. 4 is similar to that which has just been described except that it includes a shear pin 20 which, instead of being placed in a housing formed by stamping in the support plate, is carried by a plate locking 21 covering an orifice 22 formed in a reinforcement of the transparent cover 23.
  • the pin 20 is supported on a tab 24 secured to the support plate.
  • the plate 21 has on one of its sides, a groove 25 in which is engaged an edge 26 of the orifice 22 of the cover and it is applied against the opposite edge 27 of the orifice by means of a lock 28 with rotary bolt 29 which cooperates with the edge 27 of the orifice 22.
  • the plate 21 and the orifice 22 advantageously have a square shape and the plate carries spare pins 20 arranged at equal distance from the middle of a corresponding edge of the plate.
  • the plate 21 carrying the pins 20 has a square shape, it can have the shape of a regular polygon having more than four sides, in which case, the orifice 22 must have a complementary shape.
  • the arrangement which has just been described makes it possible to avoid the use of a particular tool to allow access to the alarm device which it protects; the protective cover does not suffer any deterioration during the use of the alarm box, which avoids replacing it.
  • the only part that needs to be renewed after each use of the device is the shear pin which is a particularly inexpensive part and which is moreover available to the user in a reserve of pins provided on the support.
  • the alarm box according to the invention has the advantage over conventional alarm boxes of being of a more moderate cost price and of being moreover very easy to use. , practically without any deterioration of its constituents.
