Definitions

  • the subject of the present invention is a device for closing doors of isolated enclosures, in particular phonetically and / or thermally, for example of land, rail, sea or air transport vehicles, comprising a volume accessible to a person, lockable from the outside.
  • cold stores are used inside which the products are transported.
  • the interior of these enclosures is maintained at a temperature compatible with the preservation of these products.
  • the ambient temperature prevailing inside these enclosures is between + 10 ° and -20 ° C.
  • the enclosure must be perfectly sealed and thermally insulated. This is the reason why they are generally made of thermally insulating materials inside which a heat transfer fluid circulates.
  • a manual locking device for a closure which comprises a handle articulated on a support and biased by a spring in the direction of opening. This spring drives a latch which enters a keeper when the handle is in the closed position.
  • a pawl hinged to the handle around an axis is biased by a spring, towards a so-called hooking position in which the spout of the pawl is engaged with a lug secured to the frame to lock the handle and the latch in a closed position .
  • the tenon has a flat directed towards the bottom of the notch of the pawl while moving obliquely away from the axis of rotation of said pawl.
  • either the spout is fully engaged in the post or it slides on the flat and lets the handle reopen.
  • the handle can never be in a badly closed or badly locked position so that the door is always properly closed.
  • a device which comprises a handle fixed to the actuating member of the lock which is pivoted on a fixed support.
  • This fixed support is removably fixed in a housing by acting only from the outside by means of a screw engaged in a corresponding hole in the retaining plate.
  • the actuator is also enclosed from the outside in a housing by an opening and it cooperates with a support element to arrange it in an angular position such that it remains engaged inside said housing.
  • this unlocking is authorized by mounting the catch latching lever on a plate movable in translation, actuated by a cam button from inside and pushed back into normal position by a spiral spring.
  • the lever proper is constituted by a set of two parts articulated around a common axis and cooperating with one another and held against one another by two pin springs.
  • the reliability depends on the pressure of the pin spring which intervenes for the unlocking from the outside and / or from the inside.
  • the object of the present invention is to remedy the drawbacks of the devices currently known by providing a door closing device which can be easily unlocked from inside the enclosure.
  • An object of the present invention is to provide a simple device, easy to implement and of low cost.
  • the present invention relates to a door closing device, intended in particular for refrigerating chambers.
  • the device is in particular suitable for closing doors of refrigeration chambers, such as chambers associated with refrigeration trucks intended for the transport of food or perishable products.
  • FIG. 1 which illustrates a first embodiment, we see a housing 1 of parallelepiped shape.
  • This case is here made of stainless steel but it could be, depending on requirements, made of any other type of suitable material such as aluminum or hard plastic.
  • the size and shape of the housing are of course variable depending on the applications but it will always be sufficient to receive a handle 7 of maneuver which here is of substantially rectangular shape.
  • the side walls 3 and 4 and the transverse walls 5 and 6 have a rim projecting perpendicularly intended to allow the establishment of the housing 1 in a corresponding housing of the enclosure door in association with the door operating parts.
  • This installation can be carried out by any suitable technique such as by riveting, bolting, or any other equivalent means.
  • the operating handle 7 is here made of the same material as that of the housing 1. Of course, in other embodiments, it could be made of other types of material.
  • This operating handle 7 has at one of the ends 8 an opening 9 allowing the passage of a hand in order to allow its movement from an open position to a closed position as will be described later.
  • the handle 7 comprises a barrel 11 of a conventional type actuated by a key.
  • the end 12 of the handle 7 has a housing 13. Inside this housing 13, substantially in its middle part, an oblong slot is formed 14. A square-shaped part 15 is fixed by welding points at the base of the housing 13 and passes over part of its width the light 14.
  • the end 16 of the housing 13 has, in the vicinity of its transverse edge 17 a hinge pin 18 which passes right through the said housing while being subject to each of its ends 19, 20 inside an orifice 21 , 22 formed in the side walls 23, 24 of the housing 13.
  • an elastic member such as a spring 25.
  • the end 12 of the handle 7 comprises, near the wall 5 of the housing 1, a bearing 26 inside which are placed the means for housing the handle 7 inside the housing 1.
  • These means for housing the handle 7 are here constituted by a hinge pin 27 passing right through the handle 7 and the side walls 3 and 4 of the housing to come to join the complementary members for operating the door of the enclosure. .
  • a cover 28 is mounted articulated around the axis 18 and covers the housing 13 and the barrel 11 in the closed position in order to protect it.
  • This bottom 2 comprises two lateral guide rails 30 and 31 intended to cooperate with the lateral walls 4 and 5 of the handle while serving as their housing when that -this is in position closed.
  • a square piece 32 is secured by welding points opposite the oblong slot 14 so as to come, when the handle is in the closed position, pass through said slot 14 and cooperate with the piece of complementary shape 15.
  • a stud 33 projecting perpendicularly from rubber material is arranged in the vicinity of the bracket 32 to cushion the handle 7 when it is closed and to come into contact with the housing 13 in the vicinity of the barrel 11 when said handle 7 is in the closed position.
  • the means for locking the door are constituted on the one hand by a guide rail piece 40 and by a cleat 41 associated with the barrel 11 mounted on the handle 7 and, on the other hand, by a lever 42 mounted pivoting about an axis 43 inside the housing 1.
  • the means for locking the door of the enclosure are dissociated from the means for closing the handle 7 so that it is possible to operate them independently of one another. It is thus possible to open the door from the inside while leaving the handle 7 in the closed position.
  • the lever 42 is constituted by a part which has a base 44 and a horizontal apex 45 secured to two symmetrical side walls 46, 47.
  • the front face 48 of each side wall 46, 47 is inclined from top to bottom, constituting a guide ramp which opens into a notch 49 delimiting with the top 45 a housing 50 intended to receive a part of the operating handle 7 in position locked.
  • the axis 43 passes right through the lever 42 so that the latter is pivotally mounted around this axis 43.
  • This axis 43 is fixed at each of its ends in an orifice 51, 52 formed in each wall 46- 47.
  • Two springs 53, 54 which are placed on either side of a vertical median plane on the axis 43.
  • These springs 53, 54 are subject at one of their ends to the housing 1 and to the other of their ends at the top of the lever 42 so that they accompany the pendulum movement of the lever 42 by requesting an elastic force.
  • the means for unlocking the door of the enclosure consist of a housing 50 of the pivoting blocking part of the handle at the level of which the cleat 41 is placed while being held there by retractable means 56 from the inside the enclosure.
  • retractable means 56 consist of a spring 57, one of the ends 58 of which is secured to the base of the lever 42 on a stud 59 and the other end of which 60 must cooperate with a stop 61 while being integral with a member link 62 which opens into an orifice 63 formed in the bottom 2 of the housing 1 to be maneuverable by a control device 64 manual or not from inside the enclosure.
  • the device according to the invention operates in the following manner.
  • This door locking operation is carried out in two stages.
  • the key must be turned in the barrel 11 to rotate the cleat 41 so that it comes to be housed in the lever 42. In this position, the cleat 41 is placed in the housing 50 while being maintained.
  • Figures 5 to 8 illustrate a second embodiment showing a variant in the operating handle.
  • housing 101 having a bottom 102 and lateral and transverse walls 103-106, inside of which is housed a handle 107 for operating, having at one of its ends 108 an opening 109 for manual operation.
  • the system for rotating the handle relative to the housing is similar to the previous mode and its locking is authorized from a key cylinder 111, possibly protected by a cover 128. There is also a hinge pin 127 passing through apart the housing 101 and the handle 107.
  • the means for locking the door consist, on the one hand, of a guide ramp 140 provided on the handle in its middle part, and formed by a recess of the latter, and a cleat 141 associated with the barrel 111 and, on the other hand , by a locking lever 142 pivotally mounted about an axis 143 inside the housing 101, as illustrated in FIG. 6.
  • the lever 142 is particularly shown in FIG. 8 in the closed position, in solid lines, and in the open position, in dashed lines. At its upper part, it has a spout 144 which cooperates with the guide ramp 140 of the handle against which it is pressed by the return spring or springs 145.
  • the lever 142 has, in its part opposite the cleat 141, a housing 150 provided to cooperate with the cleat and the retractable means, the dimensions of which are greater than those of the cleat, that is to say that the latter can cross said housing.
  • this movement is prevented by a pin spring 157 secured to the lever 142 by one of its branches, in particular by a hinge pin 158 and a locking tab 159.
  • the other branch 160 is supported on either side of the housing 150, as shown in Figure 6, and opposes the rotation of the lever 142, as shown in Figures 7 and 8, if the stopper 141 is superior to him. Indeed, in this case, the branch 160 is sandwiched between the cleat 141 and the outer part 161 of the lever.
  • the branch 160 can be rotated, as shown in the broken lines in Figure 6, thanks to the control device 164 operable from the inside whose operation allows two successive times.
  • Said device 164 is for example in the form of a flexible link secured to the end 162 of the branch 160 of the pin 157 then guided in the lever, in particular by the legs 163 and 166, and opens out towards the inside, in particular through the orifice 165 provided for this purpose in the housing 101.
  • the branch 160 of the hairpin spring will move, as shown in FIG. 6, to release the cleat 141 and allow possible rotation of the lever 142 around the axis 143, then continuing said rotation, the branch 160 will be supported on the tab 163 and create a torque by the tab 166 to rotate the lever around the axis 143 and consequently authorize unlocking from the inside, even if the device is locked from the outside.
