DESCRIPTION

Household comprising a sealing device

Object of the invention

The present invention relates to a home, of the stove or built-in type, in particular of solid fuel, such as wood or gas, which comprises a sealing device.

State of the art

In order to allow combustion control and optimization in a chamber, it is necessary to control the amount of air that enters it. This generally leads to minimizing the leaks found in the combustion chamber and in particular those found in the perimeter of the access door to the latter.

In the case of combustion chambers, the high temperatures generally found impose most of the time resorting to fibrous joints that resist heat, but whose tightness is not always absolute and that need an important compression force in order to limit leaks. On the other hand, in addition to their relative permeability, these joints have a tendency to harden and stiffen under the effect of heat and, therefore, to lose effectiveness in tightness.

The need to apply an important force on the joints in order to ensure the tightness is sometimes a very penalizing restriction during the elaboration of mechanisms of the door in which it is desired to limit the opening and closing force.

In the case of doors whose opening and closing are the result of a translation, a tightness in the closed position induces permanent friction of the joint during the translation and, therefore, premature wear of the joint and also increases the force required to overcome friction during closing.

A multifunctional household comprising a door that can slide according to a translational movement is known from EP 1 445 541 B1. The door in the locked position remains tight in front of the combustion chamber thanks to a gasket. The fixed part of the home on which the door comes to slide comprises an escape that allows reducing the friction of the gasket on the fixed part during the sliding door movement towards an open position.

US 7,121,042 B2 is known as a door assembly intended to seal an opening into a chamber. The door slides according to a vertical and horizontal movement in order to avoid friction between the joint and the door when the latter is opening or closing.

Document FR 1 599 189 A is known for a sealing device for a sliding door intended for closing an opening arranged in the case of a refrigerated vehicle. The sealing device comprises deformation means of a joint in order to ensure a tightness in the closed position. The activation of the deformation means is carried out during blocking with the help of a control element. This sealing device has several drawbacks, which prevent its use in the field of a home subjected to high temperatures, either in terms of durability or safety. The drawbacks of this device will appear more clearly with the reading of the description of the invention.

Document FR 2654495 also reveals a home of the relevant prior art.

Objectives of the invention

The present invention aims to provide a solution that allows to get rid of the inconveniences of the state of the art.

The present invention aims more particularly to make a home comprising a sealing device that prevents any friction of the joint during the free translation of the door.

The present invention also intends to make a home comprising a sealing device that does not need a significant compression force of the joint to ensure perfect sealing.

The present invention thus intends to make a home that comprises a sealing device that ensures perfect sealing between the combustion chamber and the surrounding part, and that resists high temperatures.

The present invention also intends to make a home comprising a sealing device that allows to meet the safety criteria in a home.

Detailed description of the invention

The present invention relates to a home comprising a sealing device that ensures a perfect seal between an access door to an interior space and the surrounding environment. The sealing device of the present invention is advantageously used when the access door comprises a sliding wall according to a translational movement within the access door, the latter being able to additionally and optionally rotate about a horizontal or vertical axis.

By way of example, the present invention is illustrated for a built-in home that has a design such that the profile formed by the inner and outer sides of the combustion chamber is continuous, with the sole exception of the site where the wall is located. . Such home designs 1 are illustrated in Figure 1 showing the wall that can be a glass 2, the inner filling of the combustion chamber 3 and the outer frame 4. The glass slides behind the masonry according to a translational movement and thus releases an access to the combustion chamber. The present invention also extends to non-recessed homes as well as homes in which there is no continuity of lines between the inside and outside of the combustion chamber. EP 1 445 541 B1 shows examples of homes for which the sealing device according to the invention is applicable.

The home according to the invention comprises a seal fixed permanently and tightly on the fixed frame of the access door. It also includes a mechanism automatically adapted and activated by the closing movement of the combustion chamber access door. During the closing of the door, the mechanism, which will be designated by means of "deformation or application means" deforms the joint and applies it on the part that opens from the door. During the opening of the door by swinging or during the sliding of the wall towards an open position, the automatic deactivation of the application mechanism releases the joint, which ensures its return to its

fifteen

initial position (ie not applied). It should be noted that the joint is tight, therefore the deformation means can use the swelling and deflation effect of the joint in order to ensure respectively the application and release of the latter. The gasket can be mechanically swollen, either by compression of a part of the gasket that generates the swelling of the peripheral part of the gasket that ensures the seal, or by crushing a piston that generates this same swelling by means of the injection of air inside the joint. The invention thus distinguishes the deformation means that are configured to compress at least a part of the joint, and in which there is the compressed part that ensures the tightness between the fixed part and the mobile part, and the deformation means that they are configured to cause a swelling of at least a part of the joint and in which there is the swollen part that ensures the tightness between the fixed part and the movable part.

The joint according to the invention has several properties required for the application, and must also be arranged inside the home in order to reduce its overheating and related problems (dilation, loss of properties). It is flexible, returns to its initial form in the absence of deformation (remanence) and is impermeable to air, even in the absence of crushing. It is thus preferably selected from a high temperature silicone material to meet the aforementioned criteria.

The joint is likely to lengthen strongly with heat. Consequently, the sealing device according to the invention comprises a joint maintenance system in order to overcome this inconvenience, while preserving the tightness of the device. In figure 2, the gasket 5 fixed on the periphery of the combustion chamber can be visualized over the entire perimeter of the fixed door frame and the gasket maintenance system constituted by a frame 6. During placement (cold ), the joint is eventually subjected to a claim in order to extend it to a length equivalent to that resulting from thermal expansion, and this in order to avoid any risk of uncontrolled deformation during hot use. To reduce the overheating of the gasket and the loss of properties resulting therefrom, the gasket is preferably arranged backwards from the perimeter of the combustion chamber in order to avoid direct radiation. It will be seen later that additional measures can also be taken to reduce their overheating.

Figures 3 and 4 show a part of the home comprising the sealing device according to an embodiment of the invention in which the deformation means are configured to compress a part of the joint and, more particularly, of the section of the meeting. Figures 5 to 12 present in detail these deformation means and their operation.

Household 1 comprises the combustion chamber and its interior ornamentation 3, an access door comprising an outer frame 4 and a glass 2, the deformation means of the joint 5 provided with an applicator frame 7, a maintenance frame 6 of the gasket, a translation slide of the glass 8 and thermal insulators 9 disposed between the hot interior surfaces of the combustion chamber and / or between an internal surface of the combustion chamber and the joint maintenance frame in order to create a barrier to heat conduction and, therefore, reduce overheating of the joint. According to the present invention, the outer frame 4 is preferably arranged to conceal the space particularly necessary for the housing of the joint, the deformation means of the joint and the thermal insulators still in the spirit of ensuring continuity of the lines between the internal ornamentation of the combustion chamber and the exterior of the combustion chamber.

The maintenance frame 6 of the joint must have a profile adapted to the profile of the joint section in order to be able to insert into it a first part 10 of the joint, while allowing the latter to slide into the frame during its expansion . A second part 11 of the joint must, in the meantime, remain free in order to be able to be deformed by the applicator frame 7. In the example of figures 3 and 4, the maintenance frame 6 comprises a U-shaped profile, whose opening collects the first part 10 of the joint.

The joint must be drawn according to a profile that guarantees perfect contact between the door (or the door frame) and the joint when the application mechanism is active and allows it to return to its initial position (not applied) when the mechanism Application is not active. Preferably, the gasket 5 comprises in its section the first part 10 mentioned above, which may be coated in any way adapted for its fixation in the frame. The gasket 5 then comprises the second part 11, which is preferably tubular in order to avoid deformation at high temperature and on which the applicator frame 7 rests. The seal can also, after the second part, comprise a third part 12 in the form of a tongue that adheres to the glass when the door and the glass are in the closed position. The plane of this tongue can be substantially parallel to that of the glass, as shown in figures 3 and 4 in the upper position or, preferably, the third part is configured so that only its free end is applied on the glass when the door and The glass are in closed position. Thus, in Figures 3 and 4 in the lower position, the plane of the third part is substantially oblique with respect to the glass, such that only the free end is applied on the glass during closing.

As illustrated in detail in Figures 5 to 8 and, more generally, in Figure 2, the deformation means according to a first embodiment of the invention comprise the applicator frame 7 disposed on the perimeter of the fixed frame of the door, two drive rods 13 of this applicator frame each arranged on the vertical edges of the frame (only one visible in profile views). Each connecting rod 13 is articulated at its two ends on a bent pivot 14. A first end of the bent pivot 14 is thus articulated on the

fifteen

25

35

Four. Five

55

65

E12164797

04-28-2015

connecting rod 13, while the second end is integral with the applicator frame 7. The pivot axis of the pivot is articulated on a fixing 15 in the fixed frame of the door. The access door comprises on each of its vertical edges of its inner face, that is to say its face in front of the combustion chamber, a stop 16 (adjustable) integral with the glass 2. When the access door (glass + outer frame) ) and the glass are both in the closed position as illustrated in Figures 5 and 6, the vertex of the connecting rod 13 rests on the stop 16. Thus, the connecting rod 13 is pushed down and draws the pivots 14 in its path. which rotate clockwise and the applicator frame 7 is thus supported against the seal to ensure tightness. When the glass 2 slides, upwards in the example illustrated in Figure 7, to allow access to the combustion chamber, the stop 16 follows the movement of the glass, thus allowing the connecting rod 13 to rise to its maximum upper position ( limited by the pivots that stop over the fixed frame). For this, the device may be provided with a return system of the connecting rod. Thus, the applicator frame is no longer applied to the joint and the glass is thus free to move without friction with the joint. Also, in case of opening by swinging of the access door comprising the glass 2 and the outer frame 4, as illustrated in Figure 8, the joint is also released. Thus, according to the invention, the deformation means are activated only when the opening to the combustion chamber is obstructed.

As illustrated in detail in Figures 9 to 12, the deformation means according to a second embodiment of the invention still comprise the applicator frame 7 disposed in the perimeter of the fixed door frame. According to this second embodiment, the drive mechanism of the applicator frame has been modified. The access door comprises, on each of the vertical edges of its inner face, at least one wheel 17 integral with the glass 2. The wheel is intended to roll on the applicator frame 7 during the sliding of the glass 2 and to cooperate with a gap 18 arranged in this same applicator frame 7 during the activation of the sealing device. In other words, it can be said that the hollow of the frame causes the bearing to lodge at the bottom of the latter and keep the gasket in the applied position.

The sealing device according to this second embodiment also comprises one or more springs 19 fixed on the fixed frame of the access door and exert a force on the applicator frame to compress the gasket against the glass when the opening to the combustion chamber It is clogged.

Device Advantages

The perfect seal of the joint allows control of combustion in the home.

The perfect seal of the board offers the possibility of making perfectly waterproof homes with respect to the place where they are placed. This allows in particular to respond to the increased demands related to the installation in passive houses, and therefore very tight.

In the case of walls whose opening and closing are the result of a translation, the mechanism allows a pure translation of the wall, while ensuring tightness in the closed position. The absence of friction with a joint during the translation movement and the low application force necessary for the application of the joint reduce both the force necessary for this translation and the wear of the joint.

The pure translation of the wall allows to limit the thickness of the sliding groove of the glass to its strict minimum, that is to say the thickness of the glass and the manufacturing tolerances, which guarantees the effect of continuity between the interior and the exterior of the chamber for homes that have this type of design. To do this, the placement of the gasket on the fixed part also reduces the thickness of the sliding groove.

The elimination of uprights, for example oblique or curved, placed in the visual field of the combustion chamber allows to limit the direct radiation of the flames on the internal faces of the frame and, therefore, reduce the overheating of the joint.

In the case of the drive mechanism with casters, the force of application of the joint is applied by means of springs only in a direction perpendicular to the plane of translation of the glass while in the case of the mechanism with connecting rods and pivots, the frame is subjected to a movement in a vertical direction and perpendicular to the glass. The mechanism with casters also has the advantage that the force of application of the gasket does not oppose the movement of the glass, which tends to raise the glass and release the gasket involuntarily. In addition, the wheel housing in the recess allows the joint to be effectively maintained in the applied position when the opening is clogged.

The drive mechanism with casters also has the advantage that the glass can be interchangeably slid up or down.

Compared in particular with the sealing device according to FR 1 599 189 A, the device according to the invention has several advantages that can be listed as follows:

-the joint is arranged on the fixed part of the home, which allows to limit its overheating. Placing the gasket on the moving part as in the device according to FR 1 599 189 A would expose the gasket to a

E12164797

04-28-2015

strong radiation and therefore to its destruction when the glass is slid in the high position;

- the activation of the joint is carried out automatically when the opening is obstructed, unlike in the device according to FR 1 599 189 A in which the activation of the joint requires a human intervention 5 in addition to the displacement of the moving part, which poses a problem in terms of security;

-in the sealing device according to document FR 1 599 189 A, the joint is integral with a movable frame that imposes a displacement and crushing during the closing movement. This no longer allows the seal, once applied, to deform and produce a "safety valve" effect when applied. At

10 device according to the invention, under the effect of a significant pressure increase in the chamber generated for example by an explosion, the third part of the joint can be separated from the glass to ensure this "safety valve" effect. This effect is even more marked if only the free end of the third part is applied to the glass, as shown in Figure 4 in the lower position;

15 -in the sealing device according to FR 1 599 189 A, the movable frame on which the gasket is fixed is not sealed with respect to the door, while, according to the invention, the gasket is directly fixed and sealed with with respect to the combustion chamber;

-a wired device as described in document FR 1 599 189 A is not adapted to be carried

20 high temperatures In fact, the increase in temperature in use would induce an elongation of the cable of the order of 5 to 10 mm. This difference would be translated at the level of the traction spring and would lead to a crushing difference of the joint of the same order between the joint parts located at the level of the levers on both sides of the traction spring.
