    DESCRIPTION
    Isolation device
    Field of the Invention
    The present invention relates to an insulation device intended to be used in the field of heating elements, in particular to ensure thermal insulation at the level of the furnace of an oven. According to other aspects, the invention also relates to a beading tool, intended for beading the ends of a flexible sleeve, and a method of beading the flexible sleeve and for mounting the isolation device comprising said flexible sleeve.
    State of the art
    Currently, commercially available furnaces are increasingly proposing an automatic pyrolysis cleaning device. This pyrolysis program is carried out by increasing the temperature inside the oven until it reaches a temperature that approaches 500 ° C. Likewise, the counterpart of this pyrolysis cleaning is that the oven opening, generally designed by a glass leaf and accessible to the user, is very hot. Therefore, in order to avoid burns, it is necessary to insulate the peripheral contour of the oven opening to the maximum, as well as the swing itself by means of an internal isolation device that will also be effective in reducing heat losses during pyrolysis.
    Existing insulation devices may comprise braided fiberglass that is a good thermal insulator, compatible with food cooking, but not resistant to welding. However, braided glass fiber materials have a tendency to fray at the seamless edges when subjected to friction, particularly when a scourer or a cloth is passed over its surface.
    Description of the invention
    Thus, one of the objectives of the present invention is to alleviate at least one of these drawbacks. For this, the present invention proposes an isolation device intended to thermally and internally isolate the joint between an organ of

    heating and its opening, comprising the isolation device:
    - a flexible and tubular joint organ, the joint organ comprising a first extreme region and a second extreme region opposite the first extreme region, the second extreme region being attached to the first extreme region at the level of a joint zone to form a loop, and
    - a flexible sleeve comprising a tubular central portion, a first end portion and a second end portion disposed on both sides of the tubular central portion, the first end portion being flanged into the tubular central portion, the second end portion being beaded into the central tubular portion,
    the flexible sleeve being mounted around the loop and configured to cover the joint area.
    Thus, the flexible sleeve obtained is flanged in its two end portions so that the seamless edges are no longer accessible. Therefore, the seamless edges no longer fray and the braid remains in good condition. Passing a scourer or other utensil over the flanged portions of the sleeve does not result in fraying, the flexible glass fibers are folded into the central tubular portion of the sleeve with the braiding assembly.
    On the other hand, the inner folding of the first and second extreme regions of the sleeve forms an excess thickness of material that contributes to provide a slight compression of the sleeve on the loop so that the positioning of the flanged sleeve on the joint zone is more Stable than no beading.
    In this document, the verb "beading" and derived terms is understood as a step of folding an extreme portion of a tube-shaped element, in this case, for example, a tubular braid of an insulating material comprising fibers of glass, towards the inside of the tube in the direction of its central portion, so that the seamless edge of the extreme portion is no longer visible nor is it in direct contact with the outside of the tube.
    Normally, the first extreme portion of the flexible sleeve is flanged into the central tubular portion in the direction of the second extreme portion.

    Similarly, the second extreme portion of the flexible sleeve is flanged into the central tubular portion in the direction of the first extreme portion.
    Advantageously, the joint member and the sleeve are each formed at least in part by a braided material so as to provide an elasticity and flexibility to the insulation device that can be compressed slightly when mounted in an oven or in the door of an oven. This also allows the isolation device to be easily shaped according to the desired final geometry and in particular a very good adaptability to the shape of the contour of the swing.
    Preferably, the braided material incorporates glass fibers, which is a very good, lightweight insulator that respects the laws related to food safety.
    According to one arrangement, the joint organ further comprises a metal mesh so as to confer a tubular shape to the joint organ as well as an adapted mechanical resistance.
    Preferably, the second extreme region is tied to the first extreme region of the joint organ by at least one clip. This type of connection avoids a welding stage that destroys the glass fibers, resists the expected temperatures and has the advantage of being simple and quick to put into practice. This type of connection also makes it possible to avoid the creation of a material weatherstrip compared to a connection mode that needs a coating of material and allows a hollow and tubular joint organ to be preserved in any portion of the loop.
    According to a second aspect, the invention relates to a beading tool that extends according to a longitudinal direction and is intended to flange at least an extreme portion of a tubular element, such as a flexible sleeve, the beading tool comprising:
    - a portion of pressure, and
    - a portion of flange integral to the pressure portion and comprising a free end portion whose surface has a convergent shape, the edge portion being configured to fold at least one extreme portion inwards

    of said tubular element.
    This tool thus allows efficient beading of a flexible sleeve designed to cover a joint area of a loop, such as those described above.
    According to one provision, the free end portion of the beading portion has a conical trunk shape so as to facilitate the implementation of the beading.
    Preferably, the diameter of the beading tool is slightly smaller than that of the flexible sleeve so as to allow the beading tool to slide into said tubular element or flexible sleeve of which at least one end portion is flanged. This is particularly advantageous for the manipulation of the flexible sleeve that will need to be introduced around the joint organ.
    Advantageously, the pressure portion comprises at least a first tubular end portion and a second end portion integral with the flange portion. This first tubular end portion lightens the tool and allows the introduction of a first extreme region of the joint organ in its hollow part in order to facilitate the sliding of a sleeve initially mounted around the beading tool, in the joint organ.
    Preferably, the pressure portion and the flange portion are composed of two assembled metal parts. These metal parts provide a mechanical resistance to the tool and facilitate the beading of the glass fibers of the flexible sleeve as well as the sliding of the latter over the joint organ. In fact, the hardness of the metal tool makes it possible to fold the glass fiber braid more easily than if the tool were made of deformable plastic material.
    According to a third aspect, the present invention relates to a bending process of a flexible sleeve intended to form an isolation device as described above, the process comprises the steps of:
    - a) providing the flexible sleeve comprising a tubular central portion, a first extreme portion and a second extreme portion,
    - b) beading the first end portion into the tubular central portion of the flexible sleeve by means of the free end portion of the flange portion of the

    beading tool as described above,
    - c) beading the second end portion into the central tubular portion so that a flanged sleeve is obtained, and
    - d) sliding the cuff, flanged around the beading tool, so as to provide a flange sleeve prepared to be mounted on a joint organ as described above.
    Thus, this procedure allows a very simple implementation of a flanged sleeve designed to cover a loop junction zone as described above.
    According to yet another aspect, the invention proposes an assembly procedure of an isolation device as described above, the assembly procedure comprising the following steps:
    - a) providing the sleeve, flanged around the beading tool, as described above,
    - b) provide the tubular joint organ,
    - c) introducing the first end region of the joint member into the first tubular end portion of the bending tool clamping portion as described above,
    - d) slide the flanged sleeve around the joint organ,
    - e) remove the first end region of the joint organ from the first tubular end portion of the beading tool,
    - f) tie the first extreme region to the second extreme region of the joint organ so that the loop is formed, and
    - g) slide the flexible sleeve around the loop until the joint area is covered.
    This simple procedure uses a beading tool that features

    Figure 8 illustrates a way of connecting the extreme regions of a joint organ according to a mode of realization of the present invention.
    Detailed description of some embodiments of the invention
    Figure 1 illustrates an isolation device 1 comprising a flexible tubular joint member 2 forming a loop in which a beaded flexible sleeve 3 (enlargement in Figure 2) is mounted. The joint organ 2 and the sleeve 3 are formed at least in part by a braided material that incorporates glass fibers so as to confer very good thermal insulation properties to the insulation device 1. As illustrated in Figure 8 , the joint organ 2 comprises a first end region 4 attached to a second opposite end region 5 by means of a clip so that the loop intended to be pinched is formed, for example, inside an oven to insulate its opening. Since the junction zone 6 between the first end region 4 and the second end region 5 stapled can result in a thermal bridge, it is covered by the insulating sleeve 3, as illustrated in Figures 1 and 2.
    The flexible sleeve 3 comprises a tubular central portion 7, a first end portion 8 and a second end portion 9 located on the opposite side of the tubular central portion 7. As illustrated in Figure 3, when the end portion 8, 9 it is not flanged, the braid tends to fray, which can be intensified during friction that may occur during the use of the isolation device 1, in particular in an oven.
    Therefore, a beading tool 10, fully illustrated in Figure 5, is used for the purpose of beading or, in other words, folding the first end portion 8 and the second end portion 9 into the interior of the portion tubular center 7 of flexible sleeve 3 according to the beading method of the present invention. The beading tool 10 comprises two solidarity metal parts and which extend according to a longitudinal direction. These two metal parts define a portion of pressure 11 and a portion of shoulder 12, the latter being integral with the portion of pressure 11.
    As illustrated in Figure 4, the beading portion 12 comprises a free end portion whose surface has a convergent shape that can resemble a conical trunk shape. This beading portion 12 allows the first extreme end portion 8 of the flexible sleeve 3 to be effectively flanged inside the tubular central portion 7, in the direction of the second end portion 9 (Figure 3, step b) of the beading procedure).
    Thus, the seamless edge of this first extreme portion 8 is retracted on itself towards the inside of the tube formed by the central portion 7 so that it is no longer subject to friction. Once the first end portion 8 is flanged, the beading tool 10 is then used to flange the second end portion 9 (step c) and the flanged sleeve 3 asl is ready to be used in a joint zone 6. Then it slides the sleeve 3, flanged around the beading tool 10 (figure 4, step d).
    As illustrated in Figure 5, the pressing portion 11 of the beading tool 10 10 comprises a first tubular end portion 13 on the side opposite a second end portion 14 integral with the beading portion 12. This first end portion Tubular 13 is used according to step c) of the assembly procedure of the isolation device 1 for the introduction of a first extreme region 4 of the joint organ 2 (Figure 6). Then, according to step d) of the procedure, the flanged sleeve 3 is slid and mounted around 15 of the beading tool 10 in the joint member 2 (Figure 7). After the removal of the first end region 4 of the beading tool 10, it is attached by a clip (step f, figure 8) to the second end region 5 to form the junction zone 6 and the loop 2. Finally, it slide the flanged sleeve 3 until reaching the junction zone 6 so that the isolation device 1 of the invention is formed (figures 1 and 2).
    twenty
    Thus, the present invention proposes an isolation device 1 to isolate the opening of a heating element whose components are simple to manufacture and assemble, on the other hand, the assembly of this device 1 only needs a single and same beading tool. 10.
