Definitions

  • the present invention relates to a lock intended to equip the doors of technical works, in particular underground electrical or telephone networks.
  • the present invention overcomes these drawbacks by proposing a tight lock, in particular to runoff, requiring only one key which allows an authorized person on the one hand access to the opening and secondly the actual opening of the lock.
  • the lock comprises a housing in which is disposed a secret lock, surmounted by an access well inside said housing, this well having internally a thread allowing the screwing of a plug on which a polygonal impression is made authorizing the positioning of a tool, an elastomer O-ring which is inserted between the shoulder of the plug and the edge of the well ensuring the tightness of their assembly.
  • the bottom of the well is pierced with an orifice of a particular shape identical to that of the end of the key, and under this orifice is disposed a cam which can rotate under the action of the key to activate the re-entry or exit of a bolt.
  • the cam is provided at its face opposite the orifice of the well with an imprint of polygonal shape in which the key can be inserted after passing through said orifice in the well bottom.
  • the fingerprint of the cam is of a shape different from that of the end of the key, while allowing the latter to register therein so that, after the key has passed through the orifice at the bottom of the well, its rotation in the cavity of the cam causes it to be blocked in the lock when the bolt is actuated, this blocking being of course subject to the amplitude of the rotation causing the withdrawal of the bolt.
  • the cam is on the other hand pierced axially with an orifice giving access to the knob of a secret lock of the type described in French patent 2,436,237, authorizing or not the rotation of the cam.
  • the control of the wheel is carried out by introducing into the orifice at the bottom of the well, then through the cam, a tool comprising the appropriate imprint, this prior to the introduction of the key into the well.
  • the opening of the lock thus requires, firstly, the removal of the plug by means of a tool comprising the appropriate imprint, then the operation corresponding to the unlocking code of the secret lock by means of another tool. also comprising an adequate imprint, finally the introduction into the well of a key, the end of which can be introduced through the hole in the bottom of said well, as far as in the imprint of the cam.
  • the footprint of the cam is the same as that of the well cap, which may for example have a hexagonal shape while the hole in the bottom of the well and the end of the key may have a section in the shape of a hexagon, one side out of two would be hollowed out in a semicircle.
  • This preferred embodiment makes it possible to use the key on the one hand as a tool for unscrewing the plug from the well, and on the other hand for actuating the lock.
  • the lock 1 has a housing 10 surmounted a well 11 closable by a plug 12 in which a hexagonal female imprint 13 is made, the seal between the well 11 and the plug 12 being ensured by means of an O-ring 14.
  • the housing 10 also includes a bolt 15 likely to be housed in a keeper secured to the frame, the lock 1 being fixed on the opening.
  • the key 2 for performing the unlocking operations of the lock 1 has the shape of a T whose transverse branch 20 serves as a handle and has one of its ends a flat 21.
  • the end of the other branch 22 has a male imprint 23 inscribed in a hexahedron, the six faces of which are alternately flat and hollowed out in half-cylinders 24.
  • the well 11 has a bottom 16 pierced with an orifice 17 of a shape identical to that of the imprint 23 of the key 2.
  • a cam 3 provided with a lug 30 for controlling the bolt 15, has on its upper face a hexagonal imprint 31.
  • This cam 3 is crossed axially, in the middle of the hexagonal imprint 31, by a cylindrical bore 32 leading to the wheel 4 d a secret lock, the upper face of which comprises a transverse slot 40 adapted to receive the flat 21 of the transverse branch of the key 2.
  • the imprint 23 of the key 2 allows on the one hand the removal of the plug 12, corresponding to the imprint 13 of said plug, and on the other hand the passage of the key 2 through the orifice 17 of the bottom 16 of the well 11, as well as its positioning in the female imprint 31 of the cam 3.
  • the flat 21 of the transverse branch 20 of the key 2 allows the wheel 4 to be actuated by passing through the orifice 32 formed in the cam 3, by registering in the slot 40 of the wheel 4, this operation taking place immediately after the cap has been removed, before the key is inserted into the female imprint 31 of the cam 3 in order to actuate the withdrawal of the bolt 15.
  • the lock 1 must be secured to the opening, so that when the latter is open, the combination of the secret lock can be accessed, in order to modify the combination, if necessary, by an orifice 18 made on the back of the housing 10.
  • the device according to the invention makes it possible to block the key in the lock after the latter has been opened, due to the difference in shape of the orifice 17 at the bottom of the well 11 and the imprint 31 of the cam 3, this blocking implying that the rotation of the cam (3) which causes the withdrawal of the bolt (15) is by an angle less than 120 °.
