  • the sealing device comprises deformation means of a seal to ensure in the closed position a seal.
  • the activation of the deformation means is effected during locking by means of a control member.
  • This sealing device has several disadvantages which prevent its use in the frame of a fireplace subject to high temperatures whether in terms of durability or safety. The disadvantages of this device will appear more clearly on reading the description of the invention.
  • the document FR 2654495 also reveals a focus of the relevant state of the art.
  • the present invention aims to provide a solution that makes it possible to overcome the disadvantages of the state of the art.
  • the present invention is more particularly to achieve a focus comprising a sealing device avoiding any friction of the seal during the pure translation of the door.
  • the present invention further aims to provide a focus comprising a sealing device that does not require a significant compression force of the seal to ensure perfect sealing.
  • the present invention thus aims to provide a home comprising a sealing device ensuring a perfect seal between the combustion chamber and the surrounding room, and resistant to high temperatures.
  • the present invention further aims to provide a home comprising a sealing device to meet the safety criteria in a home.
  • the present invention relates to a furnace comprising a fixed part enclosing an opening towards a combustion chamber, a part movable vis-à-vis said opening and a sealing device, said movable part comprising a wall and means of sliding in translation of said wall for opening access to the opening, said hearth being characterized in that the sealing device comprises a seal disposed on the fixed part flanking the opening and means for applying said seal on the movable part configured to be activated only when the opening is obstructed, thus avoiding the friction of the seal against the moving part when the wall slides.
  • the figure 1 represents a schematic view of the lines delimiting the combustion chamber with an outer frame according to the invention.
  • the figure 2 represents an elevational view of the frame of the access door to the combustion chamber according to the invention.
  • the figure 3 represents, according to the invention, two partial views in horizontal section of the fireplace when the applicator frame does not deform the seal.
  • the third part of the seal In the view in the upper position, the third part of the seal is located in a plane substantially parallel to that of the window. In the view in the lower position, the third portion of the seal is located in a plane substantially oblique with respect to that of the window.
  • the figure 4 represents, according to the invention, two partial views in horizontal section of the fireplace when the applicator frame deforms the seal on the glass.
  • the plane of the third portion of the seal is substantially parallel to that of the window while in the lower position, it is substantially oblique with respect to that of the window.

  • the figure 12 is a side view of the upper part of the leaf and the frame of the access door provided with a sealing device according to the second embodiment of the invention, when the door is in the open position.
  • the present invention relates to a fireplace comprising a sealing device ensuring 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 in a translational movement within the access door, the latter can further and optionally pivot about a horizontal axis or vertical.
  • the present invention is illustrated for a built-in fireplace having a design such that the profile formed by the inner and outer flanks of the combustion chamber is continuous with the sole exception of the location of the wall.
  • Such fireplace designs 1 are illustrated in figure 1 showing the wall which may be a pane 2, the inner lining of the combustion chamber 3 and the outer frame 4. The pane slides behind the masonry in a translational movement and thus releases access to the combustion chamber.
  • the present invention also extends to non-recessed fireplaces as well as hearths where there is no continuity of lines between the inside and the outside of the combustion chamber. Examples of fireplaces for which the sealing device according to the invention is applicable are presented in the patent EP 1 445 541 B1 .
  • the fireplace according to the invention comprises a seal permanently attached and sealed on the frame of the access door. It further comprises a mechanism adapted and automatically activated by the closing movement of the access door to the combustion chamber.
  • the mechanism which will be called “deformation or application means”
  • the automatic deactivation of the application mechanism releases the seal which ensures its return to its initial position (ie no applied).
  • the deformation means can use the effect of swelling and deflation of the seal to respectively ensure the application and release of the latter.
  • the seal can be inflated mechanically, either by compressing a portion of the seal causing the swelling of the peripheral portion of the seal ensuring the seal, or by crushing a piston generating the same swelling via the injection of air within the joint.
  • the deformation means which are configured to compress at least a part of the seal and where it is the compressed part which ensures the seal between the fixed part and the mobile part, and the deformation means which are configured to cause swelling of at least a portion of the joint and where it is the inflated portion which seals between the fixed part and the moving part.
  • the seal according to the invention has several properties required for the application and must also be disposed within the focus so as to reduce its heating and related problems (expansion, loss of properties). It is flexible, resumes its original shape in the absence of deformation (remanence) and is impervious to air even in the absence of crushing. It is thus preferentially chosen in high temperature silicone material to meet the aforementioned criteria.
  • the sealing device comprises a seal holding system to overcome this disadvantage while preserving the tightness of the device.
  • the gasket 5 fixed around the combustion chamber around the entire frame of the door frame and the system for holding the gasket constituted by a frame 6.
  • the The seal is optionally subjected to prestressing in order to lengthen it by a length equivalent to that resulting from the thermal expansion, in order to avoid any risk of uncontrolled deformation during hot use.
  • the seal is preferably arranged behind the edge of the combustion chamber to avoid direct radiation. It will be seen later that additional measures can also be taken to reduce its heating.
  • the figures 3 and 4 have a portion of the hearth comprising the sealing device according to one embodiment of the invention wherein the deformation means are configured to compress a portion of the seal and, more particularly, the section of the joint.
  • the Figures 5 to 12 present in detail these deformation means and their operation.
  • the fireplace 1 comprises the combustion chamber and its interior lining 3, an access door comprising an outer frame 4 and a window 2, the deformation means of the gasket 5 provided with an applicator frame 7, a support frame 6 of the seal, a translational slide of the glass pane 8 and thermal insulators 9 disposed between the hot inner surfaces of the combustion chamber and / or between an inner surface of the combustion chamber and the seal holding frame to create a barrier heat conduction and thereby reduce the heating of the joint.
  • the outer frame 4 is preferably arranged so as to conceal the space required in particular for the housing of the gasket, the deformation means of the gasket and thermal insulators always in the spirit of ensuring the continuity of the lines between the internal lining of the combustion chamber and the outside of the combustion chamber.
  • the support frame 6 of the seal must have a profile adapted to the profile of the section of the seal so as to insert a first portion 10 of the seal while allowing the latter to slide in the frame during its expansion.
  • a second portion 11 of the seal must remain free in order to be deformed by the applicator frame 7.
  • the holding frame 6 comprises a U-shaped section whose opening accommodates the first part 10 of the seal.
  • the gasket 5 comprises on its section the first part 10 mentioned above which can take any form suitable for its attachment in the frame.
  • the seal 5 comprises following the first part the second portion 11 which is preferably of tubular shape to prevent its deformation at high temperature and on which the applicator frame 7 comes to rest.
  • the seal may further after the second portion have a third portion 12 in the form of tongue that adheres to the glass when the door and the window are in the closed position.
  • the plane of this tongue may be substantially parallel to that of the window as shown in FIGS.
  • the third part in the upper position or, preferably, the third part is configured so that only its free end is applied to the window when the door and the window are in the closed position.
  • the plane of the third part is substantially oblique with respect to the window so that only the free end is applied to the window during closing.
  • the deformation means comprise the applicator frame 7 disposed on the periphery of the frame of the door, two actuating rods 13 of this applicator frame each disposed on the vertical edges of the frame (a only visible on the 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 rod 13 while the second end is secured to the applicator frame 7.
  • the pivot axis of the pivot is hinged on a attachment to the door frame.
  • the access door has on each of the vertical edges of its inner face, i.e.
  • a stop 16 integral with the window 2.
  • the access door windshield + outer frame
  • the window When the access door (window + outer frame) and the window are both in the closed position as shown in FIGS. figures 5 and 6 , the top of the connecting rod 13 comes to rest on the stop 16.
  • the connecting rod 13 is pushed back downwards and drives in its stroke the pivots 14 which pivot in the direction of clockwise and thus come to support the applicator frame 7 against the seal to seal.
  • the stop 16 follows the movement of the window thus allowing the connecting rod 13 to go up to its maximum upper position (limited by the pivots abutting on the frame).
  • the device may be provided with a rod return system.
  • the applicator frame no longer applies to the seal and the window is thus free to move without friction with the seal.
  • the seal is also released.
  • the deformation means are only activated when the opening towards the combustion chamber is obstructed.
  • the deformation means still include the applicator frame 7 disposed around the frame of the door frame.
  • the actuating mechanism of the applicator frame has been modified.
  • the access door has on each of the edges vertical of its inner face at least one caster 17 integral with the window 2.
  • the caster is intended to roll on the applicator frame 7 during the sliding of the window 2 and to cooperate with a recess 18 formed in the same applicator frame 7 when activation of the sealing device.
  • the recess of the frame calls the bearing to be housed in the bottom of the latter and to maintain the seal in the applied position.
  • the sealing device further comprises one or more springs 19 fixed on the frame of the access door and exerting a force on the applicator frame to compress the seal against the window when the opening to the combustion chamber is obstructed.
  • the mechanism allows for a pure translation of the wall while ensuring sealing in the closed position.
  • the absence of friction with a joint during the translational movement and the low application force necessary for the application of the seal reduces both the force required for this translation and the wear of the seal.
  • the pure translation of the wall makes it possible to limit the thickness of the sliding slot of the pane to its strict minimum, ie the thickness of the pane and the manufacturing tolerances, which guarantees the effect continuity between the inside and the outside of the room for homes with this type of design.
  • the placement of the seal on the fixed part also makes it possible to reduce the thickness of the sliding groove.
  • the erasure of amounts, for example oblique or curved, placed in the field of view of the combustion chamber limits the direct radiation of the flames on the internal faces of the frame and, thereby, to reduce the heating of the seal.
  • the application force of the seal is applied via springs only in a direction perpendicular to the plane of translation of the window, whereas in the case of the mechanism with connecting rods and pivots, the frame is subjected to movement in a vertical direction perpendicular to the pane.
  • the mechanism with wheels thus has the advantage that the application force of the seal does not oppose the translational movement of the window, which tends to raise the window and release the seal involuntarily.
  • the housing of the wheel in the recess can effectively maintain the seal in the applied position when the opening is obstructed.
  • the actuating mechanism with wheels also has the advantage that the window can be indifferently sliding upwards or downwards.
