Definitions

  • the present invention relates to a fastener device in accordance with the introduction to the main claim.
  • a known device associated with a wall close to an opening in said coldroom relative to which the door moves (along a path parallel to a floor or lower surface), comprises a seat into which an element projecting from the door, such as a hook-like element or chain, penetrates. On penetrating into the corresponding seat, this projecting element is locked therein in order to fasten the door to the wall in its closed position.
  • Another known solution uses a device formed with two parts movable relative to each other in the manner of a sliding drawer to retain between them a projecting element, specifically a chain, of the sliding door.
  • the two parts can be moved relative to each other if released by a key, whereas they are automatically locked when one is positioned on the other after receiving the projecting door element within them. Only when in this position can said key be removed from the known device.
  • This solution is complicated in use because an operator has to use both hands to achieve coupling between the device and the projecting door element, this being extremely uncomfortable.
  • the key is always associated with the known device when the door is open, hence lacking security.
  • US 3 870 354 describes a drop bolt locking combination capable of snap latch operation with a resiliently biased bolt element and cooperating strike member which enables the bolt element to be moved to a withdrawn position and then snapped into locking arrangement with the strike member upon closing of the door.
  • the bolt element has a plurality of fingers having spring biased ball bearing therein while the strike member has beveled flanges thereon for engaging the ball bearings and moving the bolt element a sufficient distance against spring biasing to permit closing of the door without the necessity of withdrawing the bolt element by knob operation.
  • EP 1 701 119 A2 discloses a fastener device for a coldroom pivoting door comprising a pusher member connected to a pushbutton positioned within the coldroom.
  • the object of the present invention is to provide an alternative fastener device for a coldroom sliding door, which enables the door to be opened from inside the coldroom.
  • a particular object of the invention is to provide a fastener device for a coldroom sliding door which enables this latter to be fastened in its closed position totally automatically without the need for an operator to intervene on the device.
  • Another particular object is to provide a device of the stated type which does not require any vertical movement of the door relative to the surface along which it slides, and which therefore does not require particular means to ensure door sealing once it has been retained by said device.
  • a device of the invention is indicated overall by 1. It comprises a body 2 presenting two components 3 and 4, the first component 3 presenting a locking mechanism for a sliding door (not shown), said mechanism being protected by the second component 4 (being inserted into a cavity 5) when this latter is coupled to the first component.
  • the body 2 comprises a hook-shaped portion 7 presenting a first part 8 disposed parallel to and spaced from a portion 9 of the first component 3, to hence define an aperture 10 through which the projecting element, in this case a ring 11 of a chain (not shown) associated with the sliding door, is inserted to lock the movement of said door after it has closed an opening provided in a wall (not shown).
  • the device 1 is positioned on this wall, in proximity to the opening.
  • the hook-shaped element is defined by an L-shaped portion 15 presenting a first part 16 perpendicular to a base 3A of the component 3, and a second part 17 parallel to this base, this latter being disposed above the portion 9 of the first component 3 of the body 2.
  • the lever element 22 presents a free end 26, preferably carrying a locking member 25 for the projecting door element 11.
  • This member is defined in the illustrated example by a spherical body associated freely with (or glued to) said end 26, and emerges from an aperture or seat 29 provided in the portion 9 of the component 3 of the body 2.
  • This portion 9 is an element coupled to the shoulders 18 and 20 of said component 3.
  • the spherical body or locking member 25 of the lever element 22 can assume two working positions relative to the corresponding seat 29: in a first position (shown in Figures 1 , 2 and 6 ) it projects therefrom to enter the aperture 10 of the body 2, while in the second position it retracts into said seat to free the aperture 10.
  • the retraction movement into the seat occurs totally automatically when the projecting door element 11 is inserted into the aperture 10, by its pressure on said spherical body 25. This pressure is transferred to the lever element 22, which rotates with the shaft 21 against the spring 23 (or equivalent elastic element) to hence enable the sphere to retract into the corresponding seat.
  • the spring 23 returns the spherical body 25 to the outside of its seat 29, to lock the projecting element or chain ring 11 within the aperture 10 of the device 1 (to hence fasten the door to the device 1 in its closed position).
  • a rotary element 30 is provided presenting an arch-shaped portion 31 rising gradually from a base 32 such that an end 31A of this portion 31 is sunken relative to a second end 31 B thereof.
  • the element 30 is mounted about a pin 35 of the first component 3 of the body 2 and can rotate about it by the action of a usual door lock 38 (positioned on the base 32) having a known pawl 39 which cooperates with a tang 40 projecting laterally from the portion 31 of the element 30 and is integral therewith.
  • the device 1 is mounted on the wall vertically, such as to present the aperture 10 facing the surface along which the door slides.
  • the key with one hand by the user
  • the element 11 is allowed to escape by gravity from said aperture 10 when the spherical body 25 retracts into the corresponding seat.
  • a cylindrical element 49 extends on one side 50 of the first component 3 of the body 2 of the device 1 (the side on which said first component 3 is fixed to a wall), and is associated with a rod 51 connected to a pushbutton (not shown) positioned inside the coldroom.
  • This solution enables the door (when closed) to be opened from inside the coldroom, to enable a person present therein to leave.
  • the rod cooperates with a portion 54 of the lever element 22; this cooperation results in lifting of the end 43 of the element 22 from the base 3A of the first component 3 of the device body 2, i.e. a rotation of the element 22 about the shaft 21, this rotation causing the spherical body 25 to retract into its seat and the subsequent release of the element 11 from the fastener device, making it possible to open the door from inside the coldroom.
  • the spring 23 cooperates with a lever 56 comprising a first arm 57 (acting on the spring 23) and a second arm 58, said lever being pivoted about a pin 60 associated with the component 3 of the device body 2.
  • the arm 58 presents an end portion 58A cooperating with a switch 62 (associated with an electrical connection positioned within the component 3 of the body 2) operating an electric motor for automatically moving the door into its open position.
  • the spherical body 25 is freely supported by the end 26 of the lever element 22 and cooperates, urged by said element 22, with a stop element 65 rigid with the second part 17 of the L-shaped portion 15 rigid with the first component 3 of the device body 2.
  • the use of the device of the invention is apparent from the aforegoing description.
  • the device is easy to use by the user in that in order to fasten the door in the closed position, the user does not have to act on the device 1, while to open the door the user has merely to rotate the key in the lock, leading to the simple release, advantageously by gravity, of the element 11 from the device 1.
  • the key serves only to open the door and can be removed after opening.
  • FIGS 7 to 10 show a variant of the invention.
  • the lever element 22 can be seen provided with a (lateral) portion 100 facing the second arm 58 of the lever 56.
  • the portion 100 comprises a recess 101 bounded by raised edges 102 and 103 with which a projecting tooth 104 associated with said second arm 58 cooperates.
  • This tooth has an undercut and is arranged to rotate the lever element 22 about the shaft 21 when the ring element 11 is inserted into the aperture 10.
  • the ring presses on a pin or pawl 110 associated with the part 16 of the portion 15 and movable within a seat 111 thereof.
  • the pin 110 penetrates into the seat until it contacts the lever 56 and makes it rotate about the pin 60.
  • This rotation causes said tooth 104 to act on the end 102 of the recess 101, to rotate (by thrusting) the lever element 22 about the shaft 21.
  • the spherical body or locking member 25 becomes positioned against the stop element 65 to lock the element 11 within the aperture 10.
  • Said element 11 is released by a key as in the case of the embodiment of Figures 1-6 or by the action of the rod 51 on the element 22. It should be noted that once the spherical body has been brought into its seat 29, it remains therein as the spring 23 tends to maintain the lever element 22 rotated such as to urge the spherical body 25 to the outside of said seat 29.
  • the spring 23 presents a second end 23K superposed on the end 43 of the lever element 22.
  • lever element 22 can present an end body 25 integral with it or shaped differently from a sphere; this embodiment and others obtainable by the expert of the art, always in accordance with the appended claims, are also to be considered as falling within the scope of the present invention.
