Abstract

The opening device comprises a support (1) on which three bars (7,8,9) are held by pivots (2,3,4). The central bar (8) is flat with the other two bars so that it can be tipped to the right or left. Once opening from one side has started it is impossible to open from the other side until the closed position has been attained.

Description

<Desc / Clms Page number 1>

The present invention relates to a device for opening a door with a horizontal opening, a window with a horizontal opening, a cupboard door, cupboard, vehicle, or any kind of panel having this. right or left function at will and according to the need of the moment.

Part of the system being adapted at the bottom. it is therefore necessary that there is a ledge at the base of these various elements. That is to say that if a door comes close to the ground, there must be a ledge at its base and on its internal face. Example: a step on which it closes. Or if it is raised above the ground such as a window, we use the part of the support, probably in this case a wall to fix the lower part of the system.

The most interesting adaptation for this invention seems to be a refrigerator and / or freezer with one or more doors. These doors are not necessarily flat, if they have any various shapes or curves, the centerpieces of this invention can be adapted. to these forms.

These household appliances are also equipped with pivot systems that can be moved from one side to the other of their doors, which allows a choice of opening to the right or to the left, this choice imposing itself according to the location chosen for the appliance. This does not always make things easier in certain apartment kitchens or other. One of these devices that can be opened at any time on the right or on the left can prove to be particularly practical to use, the system adapted to a built-in or integrated refrigerator and / or freezer can allow a choice location between the cooking appliances and the living room according to the configuration of the rooms in the house. In the case of a built-in model, the two doors, that of the appliance and that of the fitted kitchen must be equipped with the system.

The lower part of the system can be at the base and behind the door if the location is sufficient, on the other hand if the basic system is fixed under a raised door, it will be provided with any cover.

In addition, the very design of the invention was designed with the aim of offering maximum security.

Unless there is a manufacturing defect, it is impossible to open the door on the right if you have started to open it on the left and the reverse is reciprocal There are no major risks for the user, a an additional system to improve hold-up will also be provided.

As well as an additional security system with double handles.

The accompanying drawings illustrate the invention.

Figures 1, 2 and 3 serve to present this invention as simply as possible.

The following figures represent its most interesting adaptation on various refrigerators and / or freezers with one or more doors, as well as the additional systems which are added to it.

In these figures 1,2, 3 the support (1) is supposed to represent all imaginable bodies capable of being fitted with a door or a window (Ex carcass for a refrigerator, wall for a window, etc ... ).

As for the bar (8) it can be a door in itself or the support on which it will be fixed.

Referring to Figure 1 we see a support (l), on this support are maintained on each side of the bars (7 and 9) which are maintained on supports (6) which allow them to pivot opposite one the other.

These bars (7 and 9) are each provided opposite their pivot support (6) with another pivot system allowing them to hold a bar (8) between them.

So there are four pivots (2,3, 4, and 5)

<Desc / Clms Page number 2>

 The center distance of pivots (2 and 3) is identical to the center distance of pivot (4 and 5) and this also applies to the three bars (7, 8, 9).

The bars (7 and 9) are identical but they accompany the bar (8) independently of one another depending on whether the latter is opened to the right or to the left.

So if I open the bar (8) on the left, it pivots on! e pivot (2) of the bar (7) and the pivot (4) of the bar (9).

So, as we always see in Figure 1 as soon as we start to open the bar (8) on one side, for example on the left, as soon as the pivots (5 and 3) are no longer superimposed, it becomes impossible to '' open the bar (8) on the right because the pivots (2 and 3) can no longer move away from each other unless the bar (9) is able to lengthen and vice versa in the other opening direction.

Of course we must limit the degree of opening of the bar (8) to less than ninety degrees, otherwise we risk at this time there to see the pivots (4 and 2) deviate and the support assembly (l ), bar (7,8, 9) to be squared and with a weight fixed on the bar (8) one would cause the fall of the body supposed to replace the support (l).

So an opening race limited to seventy degrees would be ideal. So as we can see, we cannot choose to open the bar (8) to the right or to the left only when the pivots (3 and 5) are superimposed one above the other and the pivots ( 2 and 4) are also superimposed. Figure 2 shows a side view of the system and Figure 3 the opening opposite to Figure 1.

Note on all three figures that the bars (7 and 9) have at their pivots (3 and 4) a flange allowing them to come to bear on the support (l) so that the different pivots (2,3 , 4,5) remain well superimposed.

Figure 4 shows the principle of the invention adapted to a refng and / or freezer with a single door.

Compared to Figure l, all of the parts presented will be much larger and more resistant given the weight of the door (IO) of the device presented.

 There are two bars (13) which have a cylindrical pivot (77), the length of these pivots (77) is important for maintaining the square of the assembly as well as to avoid functional clearances in the closed position, it is necessary that the whole is fairly rigid.

So either the pivot (77) is an integral part of the bar (13) or it is very securely held there (welded, screwed; or other), this assembly must be made of metal insensitive to rust.

A washer (78) is interposed to hold the door (10).

The parts (16 and 17) are fixed to the inside of the door (mio) before foaming, by gluing or screwing (screws 19) as desired.

The part (15) makes it possible to join the parts (16 and 17) together which both have an orifice (18) allowing the degassing of the foam.

The part (16) differs from the part (17) by being closed on the top. The parts (15, 16, 17) fit one on the other to form a unit but they can also be one and the same part.

In this assembly is introduced the pivot (77).

The bar (13), support (12) assembly is the same as below.

Of course in this figure 4 the door (10) of the refrigerator replaces the bar (8) of the figures (1,2,3) and the support (l) of these same figures becomes the carcass of the refrigerator.

<Desc / Clms Page number 3>

Les supports pivots (12) des barres (13) doivent être aussi en métal. On voit aussi une vis (14) qui peut servir de pivot.

The pivot supports (12) of the bars (13) must also be made of metal. We also see a screw (14) which can serve as a pivot.

The door (IO) has two handles (l 1) for the double opening. Figure 5 always shows a refrigerator, but this is differentiated by the fact that it has a double pivot system at the top and bottom.

The bar (13) is identical but the bars (22) are thinner, the thicknesses and the shapes of these bars can vary according to the desired resistance.

There is a long double handle (20) and longer pivot supports (21,28) which we will see next.

This double bar system can provide better door retention (10).

All of the bars (13, 22, 27) presented so far are visible, plastic covers (23) will be fitted in front.

In addition all the bars (13, 22.27 ect ...) can each have an individual plastic cover because depending on whether you open the door (lO) to the right or left they appear from the front or from back.

Figure 6 shows an enlargement of the pivot supports (21, 28) which, as can be seen, allow when the various bars (13,22, 27,24) open, the cover (23) to enter a notch Also as see figure 6 the pivot supports (21,28) have a different height adapted to the bar they receive.

The large pivots (77) of the bars (13, 22, 27, 24) can be hollow metal tubes filled with thermally insulating material.

The pivot supports (21) are here represented here in abutment on the carcass (25) of a refrigerator and / or freezer.

The bars (22) have a pivoting end piece (80) intended to be held in a cover (23).

Figure 7 shows a two-door refrigerator and / or freezer (top freezer).

We see here a system of bars (29,27) held together on the same pivot support which allows the door (I 0) and the door (26) to operate independently of each other while needing less space only for two separate pivot supports. Also Figure 7 shows various types of pivot supports (30) with a support and visible screws, or (31) perforated on the inside for hidden screws, or a set of pivot supports (34) allowing better maintenance of thicker bars (32,33), these pivot supports (34) can be fitted separately from above and below these bars (33,32).

Figure 8 shows one of the handles (11) present in Figure 4, this handle (l 1) is provided inside another handle (35) which pivots by coming to push a part (37) which takes support next to the joint (39).

This handle (35) is equipped with a spring (36). It also has orifices (43) allowing it to pivot after fitting onto the pivots (44) of the handle (l l).

On the two handles there are various flanges (38) for holding the spring (36).

In the cutouts (42) of the handle (35) the pivots (41) of the part (37) are introduced.

In the handle (l 1) there is a cutout (40) which allows it to slide while holding the part (37). This handle system is intended to facilitate the opening of the complementary closure system which is described in FIG. 9.

In this figure 9 there are pivot supports (21) on which are mounted parts (48) provided with pivots (50), a part (46) retains a spring (47) which pushes the part (48).

<Desc / Clms Page number 4>

 This piece pushed on its stop (55) must then be located so that its pivot (50) is in the same pivot axis as the bar (27, 22, ect ..) maintained on its pivot support (21 ).

The part (48) pivots on an axis (81) The bar (45) pivots a part (49) at each of its ends.

This part (49) has a double system of pivots, a pivot (83) allowing it to be held on the bar (45) and a pivot (82) which will be fixed to it on a bar (22,27, 13, ect. ) because this additional locking system works with a double bar system like the one shown in Figure 5.

Still in FIG. 9, a part (49) has a pivot (82) fixed on a bar (example 22).

autour des pivots (50) des pièces (48) Sur la barre (45) il y a donc une piècc (49) qui est fixée sur une barre (22) et une pièce (49) qui est elle-même fixée sur une barre (27). Ainsi quand on ouvre une porte (lO) d'un coté, une pièce (49) quitte le pivot (50) de la pièce (48) en pivotant autour du p ! vot (50) et en poussant le ressort (47), elle passe en quelque sorte un point mort. Its fixing on this bar is on the side of the maintenance of the bar on the door (IO) because this part (49) accompanies the opening movements and it has a curved face which allows it to pivot itself

around the pivots (50) of the parts (48) On the bar (45) there is therefore a part (49) which is fixed on a bar (22) and a part (49) which is itself fixed on a bar (27). So when you open a door (10) on one side, a part (49) leaves the pivot (50) of the part (48) by pivoting around the p! vot (50) and pushing the spring (47), it somehow passes a neutral position.

The spacing of the pivots (82) of the parts (49) which are in turn fixed to the bars (22, 27) should only allow the opening of one part (49) at a time.

It should not be possible to open the two parts (49) fixed on the same bar (45) at the same time.

Thus by opening a door (10) as soon as a part (49) leaves the pivot (50), the one which is opposite comes to pivot inward around its pivot (50) thus increasing the holding as a additional security.

On one of these sides, the bar (45) has a cutout (51) which must be just sufficient to allow it to follow the opening movement of one of the parts (49), because when the latter will pivot on its axis fixed (82), its movable axis (83) will need an offset to the outside.

The size of the cutout (51) of the bar (45) should also only allow the opening of one piece (49) at a time.

While in the fully closed position of a door (IO) the pivots (50) of the parts (48) will push on the parts (49), the door (10) will be closed as much as possible.

Figure 10 shows all the parts of Figure 9 installed in rear view of the assembly.

We see that the part (48) has an internal cavity (84) larger than the part (46) thus allowing the spring (47) to have the ease necessary for its operation.

Also the part (23) has a part (56) allowing to fit the bar (22) which will be maintained while being able to pivot.

This part (23) also has a cutout (57) allowing easier fitting.

FIG. 11 presents the system of the long handle (20) of FIG. 5.

This handle (20) has two internal handles (64) provided with orifice (86) and oblong holes (87).

The orifices (86) fit onto the pins (66) of the long handle (20) thus allowing them to pivot.

The two handle (64) are coupled together by a bar (65) which will move from one side to the other, driven by the tilting of one of the handle (64) then causing the other handle (64) in the reverse movement.

<Desc / Clms Page number 5>

By any system of pivots. the bar (65) is held on the handles (64) at their oblong holes (87).

The ends (88) of the bar (65) are also coupled with parts (62) against the door (IO) by a fixed pivot system (89) On each side of the door (10) the part (62) penetrates inside a room (61).

When a part (62) leaves its part (61) the part (62) which is opposite enters its part (61).

This system keeps the door (lO) closed either on one side or the other by tilting the handle system (64). This is therefore again an additional safety element. Between the two handles (64), a piece (67) on which are fixed by a fixed pivot (90) two parts (69) act on a part (68) which in turn pushes on a spring (70).

This spring (70) is also held on the other side by another part (68).

The bar (65) has axes (71) for tilting parts (69) from one side to the other, thus compressing the springs (70) before tilting on the other side.

The parts (68) have cylindrical pins allowing them to tilt.

This system is used to hold the handles (64) in the chosen position.

The parts (62) are held by the door (10) by parts (63) and the parts (61) are held on the carcass (25) of the refrigerator.

Figure 12 shows various views of the bar (65) with its cylindrical axes (71) which are provided with cutouts that can receive external clip clips to hold the parts (69) on each side.

FIG. 13 shows the operating principle of the part (62) when it is introduced into the part (61) presented here in section.

quarante-cinq degrés. It can be seen that the part (61) is designed to allow the part (62) to pivot in order to then follow the curve of the latter when the latter penetrates inside. From this moment the part (62) can no longer s '' open, thus preventing the double handle system (64) from tilting. FIG. 14 shows us that when the door (10) opens relative to the carcass (25) of the refrigerator, the part (62) abuts on the part (61), thus mutating the opening angle of the door (IO) of about

forty-five degrees.

The door opening angle (10) must never reach ninety degrees, but the system can be designed to allow an intermediate opening angle.

Figure 15 shows the handle (64) in different views.

Figure 16 shows the assembly of parts (62,63) pivoting on their common axis by means of a pivot (72) which can be held by a clip.

Figure 17 shows all the parts that allow the tilting of the double handle system presented in Figure 11.

The holes (73) of the part (67) are used to fix it on the friend (10) of the refrigerator.

Figure 18 shows all the parts (62,63, 64) mounted together.

We see two spacers (71) interposed to center the part (62) on the handle (64).
