Description

PIECE OF ARTICULATION AND MAINTENANCE

  A PANEL LIKE A DOOR ON ANOTHER ELEMENT.

  The invention relates to a piece of articulation and hand-

  of a sign such as a door on another element, in parti-

  to use a frame as a support.

  It applies more particularly to types of panels that may be subject to accidental stresses during their use, and is intended to prevent their deterioration.

to these constraints.

  It is known that when a door is accidentally forced beyond its maximum opening position, the door or even the elements that support it, such as the pivots or the hinges, are deteriorated, following the constraints that occur. exert on all or part of these elements near the axis of articulation. He is coming

  sometimes that this. also the element to which the door is

  abutment, for example the support frame, which is damaged.

  In order to overcome these drawbacks, stop systems have been invented which limit the mechanical stresses exerted.

  near the axis of articulation when the door is forced to

  beyond its maximum opening position.

  However, it is sometimes impossible to place stops to prevent the displacement of the maximum position, for aesthetic reasons and / or congestion. This is the case, for example with storage furniture such as refrigerated cabinets, in which the closure is provided by a main door and at

  within which there are sometimes compartments which

  each go their own door, to isolate them from the outside

  when the main door is open.

  In a refrigerator, for example, the ice-making compartment is isolated using such a door, and in some front-loading freezers that have several

  compartments, each compartment is closed by its own door.

  In these different types of furniture, the articulation of the doors of the various compartments is provided either with hinges or with the help of pivots and is carried out either around a horizontal axis or

around a vertical axis.

  In the case of refrigerated cabinets, these doors have only an insulating role and, as a result, are often carried out in a

  fragile material. It may happen that such a door is forced beyond

  beyond its normal maximum opening position, and then an abnormal stress occurs near the axis of articulation,

causing deterioration.

  It frequently happens, for example, that the main door of

  the refrigerating cabinet closes while the door of a

  is open: it is then the main door which exercises the

  abnormal stress on the compartment door.

  This type of incident is frequent in the case of refrigerated cabinets and, when it occurs, it is necessary to change the

door that has been damaged.

  The piece of the invention overcomes these disadvantages by avoiding, when used on a door that may be subject to stress, the deterioration of the door or even its own deterioration. According to the invention, a piece of articulation and maintenance of a panel on another element comprises a seat to ensure its attachment to the panel, a pivot to cooperate with a hole in the support element of the panel and ensure the articulation, and a connecting portion between the pivot and the seat and is characterized in that one of these constituent elements is deformable by elasticity. Thus, when a panel such as a door is hinged to another element using such a room, if an abnormal stress is exerted, it follows a deformation of the room that prevents the deterioration of the door either the support element or the

connecting piece itself.

  Since this is an elastic deformation, when the

  trainte ceases, the piece returns to its original form.

  According to another characteristic of the invention, it is the part

  connection between the pivot and the seat which is deformable by elasticity.

  Thus, there is absolutely no more stress in the junction zone between the door and the room, that is to say at the level of the seat and in the area of rotation between the pivot and the support element of the sign. Other features and advantages of the present invention

  will appear with the description of some embodiments

  made with reference to the appended figures in which: FIG. 1 shows a type of refrigerating cabinet compartment door of the prior art; FIG. 2 is a view of a refrigerating cabinet having

  various compartments insulated by doors fitted with

  According to the invention, FIG. 3 shows a part of the invention mounted on a door when no stress is exerted. FIG. 4 shows the part of the invention mounted on a door when it undergoes a constraint,

  FIG. 5 is a perspective view of a piece of furniture

culation according to the invention.

  Figure I shows a door 1 provided with two parts 2, 3 of articulation of the prior art. This door is intended, by

  example, when closing an internal refrigerator compartment.

  The hinge elements are two pivots 2, 3 located on two opposite edges of the door, and intended to be engaged in openings in the walls of the refrigerator. The axis of rotation of the door is the axis of the pivots. In the example shown, this axis

is horizontal.

  It is found that if in any way, a particular stress is exerted on the junction zone between one of the pivots 2, 3 and the door 1, the pivot and / or the door break or are damaged. FIG. 2 represents the inside of a refrigerating cabinet 4,

  closed by a main door 5 and comprising several compartments

  timents accessible by doors 6, 7, 8, 9 provided with hinge parts according to the invention. In this example, each door rotates around a horizontal axis. An upper compartment is closed by a door 6 hinged by two parts 61 and 62 of the invention. These parts, shown in more detail in Figures 3, 4, 5 are fixed on the door 6 and pivot in openings in the walls of the cabinet. This door 6 is represented in a

half open position.

  A second door 7, located below the door 6, is articulated by two parts 71 and 72. This door is shown in an open position, and abuts against a door 8 which is

  located under the door 7 and shown in a closed position.

  This door 8 is hinged by two pieces 81 and 82.

  In this figure, we can still see part of a door 9

  located under the door 8 and one of its articulation parts 91.

  Figure 3 shows in detail one of the articulation parts 71

  of the door 7 in abutment against the door 8, located below.

  The hinge part 71 comprises a flat seat 71a which is fixed, in the example shown, under the lower edge of the door 7. This attachment is provided either by screws, or by tongues cooperating with orifices provided on the lower edge

Door.

  In the extension of this seat 7la, in the direction of the ridge determined by the intersection of the lower edge and the side edge of the door, there is a portion-71b which connects the seat 71a to the

pivot not visible in this figure.

  The pivot is therefore at the end of part 71b, and it is

  engaged in an orifice formed inside the wall of the arm-

moire 4.

  In a preferred embodiment, shown in this figure, the pivot is carried by a flat 71c parallel to the wall of

  the cabinet, and located at the end of the portion 71b opposite to the

located 71.

  In a preferred embodiment of the invention, it is the portion 71b which connects the seat 71a to the pivot which is deformable by elasticity. This figure also shows the door 8 located below the door 7 when the latter is closed. Is also shown, between the flat 71c which is fixed to the pivot and the wall of the cabinet 4, a washer 10 whose role is to limit

  the friction between the flat and the wall.

  In this figure, the door 7 is open and abuts against the

  upper edge of the door 8 but however without constraint.

  Figure 4 shows the deformation that the joint member undergoes when a constraint is exerted on the door that it supports. In the example shown, the door 7 is plated

against the door 8.

  The seat 71a does not deform. By cons, the portion 71b of connection between the seat and the pivot is bent, which prevents the door 7 supported by the hinge part, or the door 8 against which the door 7 is plated, or still there

  wall in which is engaged the pivot are deteriorated.

  Thus the deformation of the articulation part compensates for

  constraints suffered by the various components of the device.

  When the stress stops, the whole resumes its position

  initially without any element being damaged.

  Figure 5 shows in perspective a hinge piece according to the invention. In this figure, we see the pivot 11 in

  end of the flat 71c carried by the deformable portion 71b '

  the connection between the pivot and the flat part and the seat 71a fixing to

the door.

  In this figure, we also see a set of tongues and reliefs 12 which is provided to ensure the attachment of the seat 71a and thus the hinge part to the door or any other panel that such a room is meant to articulate.

  Preferably, the articulation piece of the invention is

  in one piece, by molding or by injection of a

plastic material.

  In the described modes of use and operation, the articulation piece of the invention makes it possible to pivot a door around a horizontal axis. In addition, the room is fixed under the edge

  lower door, resulting in an opening down.

  This use is in no way limiting and it is possible to use

  the articulation parts of the invention to achieve an opening

  up, by placing the parts above the top edge of a door, or even a pivotal opening around a

vertical axis.
