Definitions

  • the present invention relates to closing devices for pivoting doors, these devices being able in particular but not exclusively to be used on doors of cold rooms or cold stores.
  • a closing device for a door pivotally mounted on a frame of the type comprising a strike assembly fixed on the frame, a handle and bolt assembly carried by the door leaf and comprising a housing fixed on the face external of the leaf and projecting from the edge of the door, a handle proper articulated on this housing around an axis parallel to the pivot axis of the door, a bolt also articulated on the housing around a parallel axis to the pivot axis of the door and located in said projecting part, this bolt being adapted to cooperate with the fixed strike, the handle comprising a part for operation by the user and an actuation part intended to cause the release of the bolt out of the keeper when operating the handle.
  • a bolt release mechanism is also provided, which comprises an operating member accessible from the internal face of the door and arranged to cause the release of the bolt and the opening of the door.
  • the housing of this device has a U-shape and the ends of the two branches of this U are in abutment against the exterior face of the door.
  • the handle itself is projecting in the bottom of the U, between the two branches of the latter, so that the user must place his hand in this U to be able to actuate the handle by pulling it towards him.
  • Such an arrangement has at least two drawbacks: it has a large thickness, and therefore protrudes appreciably over the thickness of the door. In addition, it is relatively heavy and expensive.
  • Document GB-A-2 084 643 having served as a basis for the preamble of claim 1, also describes a closing device comprising a housing fixed to the door by members accessible from the outside and which can therefore be easily dismantled. On this housing is articulated a lever or an operating handle which acts directly on the bolt and which protrudes very largely relative to the housing.
  • the invention therefore aims to provide a door closing device, of the type defined above and which is compact in thickness, can not be disassembled or broken easily, and nevertheless allows to obtain costs reduced manufacturing.
  • the closure device shown in the drawings is intended to equip a door P pivotally mounted on a frame D, around a vertical axis not shown.
  • a striker assembly 10 comprising a housing 11 and conventional fixing means which need not be described in detail.
  • an actual striker 12 here constituted by a cylindrical sleeve 13 carried by a rod 14 itself fixed between two uprights 15 integral with the housing.
  • This striker rod is arranged vertically, parallel to the vertical edge of the frame and to the pivot axis of the door.
  • the device is completed by a handle and bolt block 20 carried by the door leaf.
  • This block comprises first of all a counter plate 21 fixed on the external fax machine of the door and of which a part 22 projects on the edge of the door.
  • This counter plate is fixed by screws (not shown).
  • An actual box 24 is fixed to this counter-plate, for example by means of two screws 25 arranged in the part 22 of the plate. It is also fixed in the vicinity of the opposite edge 23 of the plate, in line with an opening 26 formed in the latter and in the thickness of the door, and which is intended to allow the passage of an operating member that the 'will be described in more detail below.
  • This housing 24 completely covers the counter plate 21 and in particular the screws for fixing the latter on the door. It comprises two side walls 27 and 28 connected to their left part by considering Figures 1 and 2 by a front wall 29 and by an end wall 30. At their other ends, the two side walls 27, 28 are connected by a second end wall 31 also constituting a base applied against the surface of the door and which delimits a space allowing access to the handle, as will be described below.
  • This base also includes an internally threaded barrel 32 which in particular constitutes an anchoring point.
  • a bolt 40 having the shape of a hook provided with a ramp 41 allowing its engagement on the keeper when the door is closed.
  • This bolt is articulated around an axis 42 and it is urged by at least one spring 43 towards its closed position.
  • This spring is wound around the axis 42 and is supported by a first branch 44 on a second axis 45 secured to the bolt and, by the end of its other branch 46, on the handle itself 50.
  • the bolt is in fact double and constituted by two identical parts connected by a spacer constituting the axis 45.
  • the handle itself has an elevational view in FIG. 2, the shape of a rectangular pallet and engages with a small clearance in the volume delimited by the lateral faces 27, 28, the front face 29 and the wall or base 31 of the housing.
  • This handle has on its internal face a rib 51 intended to come into abutment against a complementary surface 31a of the base of the housing as well as an operating part 52 disposed at its end close to the base 31. It further comprises on its face directed towards the inside of the housing two bosses 53 constituting a yoke and by which it is articulated on a cylindrical rod 54 entirely housed inside the housing and carried between the two lateral faces 27, 28 of this housing.
  • a lever 60 with three branches.
  • the first branch 61 is in abutment against the internal face of the handle, in a zone 55 of the latter arranged relative to the bosses 53, opposite the operating part 52.
  • the second branch 62 is articulated by means of an axis 63 on a connecting rod 64 which is here constituted by a double connecting rod formed by two elbowed elements which can be connected in an intermediate part by a spacer 65 and whose opposite ends 66 are articulated on the bolt, around axis 45.
  • the third branch 57 of the lever 60 is arranged opposite the orifices provided in the barrel 32 of the base, in the counter-plate 28 and in the door P.
  • This third branch is intended to cooperate with a rod 70 which is made of preferably a thermally insulating material which is slidably mounted in a guide 71 which simultaneously ensures the fixing of the base 31 on the counter plate 21.
  • This rod can be actuated from the internal face of the door, by means of 'a pusher 72 covered by a flexible cover 73 and biased towards the outside by a spring 74.
  • This device is completed by a locking mechanism with a lock allowing the handle to be locked in the closed position. That is to say in the position shown in FIG. 5.
  • This mechanism is described in more detail in Figures 5 to 8.
  • This lock 80 is carried by the handle 50.
  • it is a conventional cylinder lock known as "with European profile", comprising a body 81 fixed to the handle by means of two balusters 82, d 'a bar 83 and screws 84.
  • the barrel 85 rotatably mounted relative to the body of the lock is integral with a bit 86 which, when the key 87 is engaged in the barrel and this key is actuated, can be driven at an angle of 360 °, the key can only be engaged in the lock and released from this lock in one position.
  • the body of the lock has a cylindrical part 88 around which a metal sector 89 is rotatably mounted surrounding this cylindrical part at an angle greater than 180 °, so that it cannot escape from it laterally.
  • This sector includes a boss 90 which, in the closed position of the lock, is placed between the internal face of the handle and a stop piece 91 carried by the counterplate.
  • this sector carries a finger 92 which is axially projecting so as to be able to be on the path of the bit 86.
  • a plate 93 secured to the body of the lock has a notch 94 in which passes the finger 92, the two ends of this notch constituting two stops which limit the angular travel of the sector 89.
  • the door can be opened from inside the room or warehouse. It suffices to exert a pressure on the pusher 72, which causes the displacement of the rod 70 and the actuation of the lever 60 in a direction such that the rod 64 and the bolt 40 are actuated in the direction of the opening (fig. 1).
  • the user engages the key in the lock and turns it anti-clockwise, considering fig. 2 or fig. 7.
  • the bit 86 then moves until its face 86a comes into contact with the finger 92 and drives the sector 89 to the release position of the key (fig. 8).
  • the boss 90 is then released from the baluster 91 and the handle can be actuated normally by the user who pulls it towards him in the direction which causes the door to open.
  • the handle rotates about its articulation axis 54 and acts by its internal face on the branch 61 of the lever.
  • the latter is therefore driven clockwise by considering fig. 2, which causes the bolt 40 to be actuated by means of the rods 64.
  • the user operates the lock clockwise, considering fig. 1 or fig. 8.
  • the bit 86 turns around an angle of about 330 ° until its face 86b comes into contact with the finger 92 carried by the sector 89.
  • the latter is then driven on an angle such that the boss 90 comes to the right of the baluster 91 and therefore prevents actuation of the handle.
  • Such a device has significant advantages: first of all, it is tamper-proof because none of the fixing screws, both of the counter-plate on the door and of the housing on the counter-plate, are accessible from the outside.
  • the locking device is particularly simple and effective and does not prevent the opening operation for a user disposed inside the enclosure. It will be added that this mechanism is particularly robust and of simple construction, so that the assembly can have a relatively low cost price.
