Description

The present invention provides heating foaming that foams by heating a frame material constituting a rectangular frame disposed in an opening of a building and a frame material constituting a door built inside the frame. The invention relates to heated foam fixtures for attaching materials.

For fittings in which a door body such as a window shoji or door is built inside a frame body such as a window frame or door frame fixed to an opening in a building, in the event of a fire, the gap between the frame body and the door body There is a possibility that the gaps between the two can become passageways for flames, hot air, etc. Therefore, in the event of a fire, it has been considered to close the gap between the frame and the door using a heated foam material that foams (expands) when heated (for example, Utility Model Application No. 60-76942 (see official bulletin).

Heat-foamed materials are generally configured in the form of a plate (sheet), and are attached to the frame material that makes up the frame body or the frame material that makes up the door body using adhesive tape or adhesive. . However, heat-foamed materials generally begin to foam at around 200°C, while adhesives (including adhesives) used in adhesive tapes begin to melt at lower temperatures (e.g. around 120°C). . For this reason, the adhesive may melt before the heated foam material starts to foam, and the heated foam material may peel off from the predetermined attachment position.

Utility Model Publication No. 60-76942

In view of the above-mentioned circumstances, for example, as shown in FIG. 14, a structure in which a heated foaming material 100 is locked in a sheath-shaped groove 102 formed in a member 101 to be attached, which is a frame material or a frame material, has been developed. It can be considered to be used in place of pasting or in combination with pasting. If such a structure is adopted, it is possible to prevent the heated foaming material 100 from falling off the attached member 101 before foaming. However, the structure of locking the heated foam material 100 in the groove 102 requires that the member to be attached 101 to which the heated foam material 100 is attached be provided with the groove 102 in advance. For this reason, it is difficult to use heat-foamed materials when attaching them to existing fittings.

Therefore, it is conceivable to adopt a structure in which the heated foam material is directly fixed to the frame material or the frame material with screws. In this case, it is possible to prevent the heat-foamed material from falling off the frame material or frame material before foaming, and it is also possible to attach the heat-foamed material not only to new fittings but also to existing fittings. . However, when fixing the heated foam material using screws, a sufficient work space is required to perform the screw fixing work using a tool. For this reason, it becomes difficult to attach the heated foamed material to a position where there is insufficient work space for screwing. In this way, when the heated foamed material is fixed using screws, the mounting position of the heated foamed material is likely to be restricted.

[Fire protection structure of door device 1]
The door device 1 of this example prevents the gap between the door frame 2 and the door 3 from becoming a passage for flames and hot air when a fire occurs. For this purpose, heated foamed materials 8a and 8b, which foam at least in the thickness direction by heating, are attached to the lower frame 5 constituting the door frame 2 using a heated foamed material attachment 40.

Specifically, the heated foamed materials 8a and 8b, each extending in the in-plane direction, are attached to the lower frame 5 using a plurality of heated foamed material attachments 40. In the illustrated example, each of the heated foamed material 8a and the heated foamed material 8b is constructed by connecting two sheets of heated foamed material having a predetermined length in series in the in-plane direction. For this reason, as shown in FIG. 1, the heating foaming material fixture 40 is attached to both ends of the heating foaming material 8a and the heating foaming material 8b in the in-plane direction, and to the ends of the heating foaming material 8a and the heating foaming material 8b in the in-plane direction. They are placed in three locations in total, including the joint located in the middle. However, when carrying out the present invention, there are no particular limitations on the installation position and number of the heating foaming material fixtures. In addition, although illustration and description are omitted, for each frame 4, 6 other than the lower frame 5 constituting the door frame 2, and for each frame 33, 34, 35 constituting the frame frame body 31, a plurality of The heated foam material can be attached by various attachment methods, such as a method of locking it into a sheath-shaped groove or a method of fixing it with screws.

The heat-foamed materials 8a and 8b are plate-shaped (band-shaped, sheet-shaped) with a thickness of about several millimeters, foam (expand) at least in the thickness direction when heated, and have fire resistance. The product name "Fiblock" manufactured by Kogyo Co., Ltd. can be used. Note that the foaming start temperature of "Fiblock" is about 200°C, and the plate thickness can be about 5 to 40 times thicker depending on the type (butyl type, epoxy type, etc.). Note that as the heat-foamed material, a material that foams not only in the thickness direction but also in directions perpendicular to the thickness direction (width direction and length direction) can be used.

[Mounting structure of heated foaming materials 8a and 8b]
In this example, heated foaming materials 8a and 8b are attached to the outdoor side surface of the lower frame holding piece 16 constituting the lower frame 5 over the entire length in the in-plane direction.

Specifically, the heat-foamed material 8a is placed under the lower frame holding piece 16 with its thickness direction aligned with the indoor/outdoor direction, and with its lower end positioned on the upper surface of the outdoor lower frame substrate section 15. It is attached to the attachment surface 20 of the base 18 that constitutes the half part. On the other hand, the heated foam material 8b is placed in the upper half of the lower frame holding piece 16 with its thickness direction aligned with the indoor/outdoor direction and with its lower end positioned on the upper surface of the lower overhanging plate part 22. It is attached to the pressed surface 25 of the holding section 19 that constitutes the section. Therefore, the heated foamed material 8a and the heated foamed material 8b are arranged on the same vertical plane while being separated from each other in the vertical direction. Further, the heated foaming material 8b is arranged inside the locking groove 11b. In the illustrated example, the vertical width dimension of the heated foamed material 8a and the vertical width dimension of the heated foamed material 8b are set to be the same.

In this example, the heat foaming material 8a is attached to the surface 20 to be attached using an adhesive (adhesive) using adhesive tape, and the heat foaming material 8b is attached to the surface 25 to be pressed using an adhesive using adhesive tape. ing. Further, the heated foamed material 8a attached to the attachment surface 20 and the heated foamed material 8b attached to the pressed surface 25 are each attached using the heated foamed material attachment tool 40 attached to the lower overhang plate section 22. , suppressing it at the same time.

[Structure of heated foaming material fixture 40]
The heated foam fixture 40 is a small component formed by performing press processing such as punching and bending on a metal plate having corrosion resistance and heat resistance, such as a stainless steel plate or an aluminum alloy. The heating foaming material fixture 40 has a width dimension that is sufficiently small relative to the length dimension of the heating foaming materials 8a and 8b (for example, from several mm to several tens of millimeters) so as not to interfere with the foaming of the heating foaming materials 8a and 8b. width dimension). As shown in FIG. 5, the heated foam material attachment 40 has a clip shape with a cross-sectional shape bent into a substantially square shape, and includes an attachment portion 41 and a pair of arm portions 42 and 43. There is.
In this example, a plurality of (three in the illustrated example) heated foam material attachments 40 are used, but all of the heated foam material attachments 40 have the same configuration.

The attachment portion 41 is configured in a substantially U-shaped plate shape, and is attached to the lower overhang plate portion 22 so as to surround the front half of the lower overhang plate portion 22 . The mounting portion 41 includes an upper plate portion 44 disposed above the lower overhanging plate portion 22, a lower plate portion 45 disposed below the lower overhanging plate portion 22, and an outdoor side of the upper plate portion 44. It consists of a connecting portion 46 that connects the end portions and the outdoor end portions of the lower plate portion 45 to each other.

The upper plate part 44 has a bent part 47 bent in a substantially V shape so that the intermediate part in the indoor/outdoor direction projects downward. The vertical dimension between the lower end of the bent portion 47 and the upper surface of the lower plate portion 45 is sufficiently larger than the vertical dimension of the outdoor end of the lower overhanging plate portion 22 (including the bent portion 24b). It's getting smaller. On the other hand, the entire lower plate portion 45 is configured in a flat plate shape.

With the attachment portion 41 attached to the lower overhang plate portion 22, the bent portion 47 engages with the bent portion 24b provided at the outdoor end of the lower overhang plate portion 22 in the indoor/outdoor direction. . This prevents the heated foam material attachment 40 (attachment portion 41) from moving toward the outdoors, which is the direction in which the lower overhang plate portion 22 extends, with respect to the lower overhang plate portion 22. Therefore, the bent portion 47 corresponds to the engaging portion described in the claims. Further, with the attachment portion 41 attached to the lower overhang plate portion 22 , the upper surface of the lower plate portion 45 is in surface contact with the lower surface of the lower overhang plate portion 22 .

The pair of arm portions 42 and 43 extend from the indoor end of the attachment portion 41 in directions away from each other with respect to an up-down direction that coincides with the thickness direction of the lower overhang plate portion 22.

Among the pair of arm parts 42 and 43, one arm part 42 disposed below is configured in a flat plate shape, and is bent at a right angle downward from the indoor end of the lower plate part 45. . On the other hand, of the pair of arm parts 42 and 43, the other arm part 43 disposed above is configured in a flat plate shape, and is bent upward from the indoor end of the upper plate part 44. ing. In this example, one arm 42 and the other arm 43 are located at the same position with respect to the indoor and outdoor directions. Therefore, the indoor side surface of one arm section 42 and the indoor side surface of the other arm section 43 are located on the same virtual plane.

In this example, the vertical width of one arm 42 is larger than the vertical width of the other arm 43. In the illustrated example, the vertical width of one arm 42 is about three times the vertical width of the other arm 43. The vertical width of one of the arm portions 42 is approximately the same as the vertical width of the heated foam material 8a, and is slightly smaller than the vertical height of the mounting surface 20. The vertical width dimension of the other arm portion 43 is smaller than the vertical width dimension of the heated foam material 8b and the vertical height dimension of the pressed surface 25 (in the illustrated example, it is about 1/2). . Note that the width dimensions of one arm portion 42 and the other arm portion 43 in the in-plane direction are equal to each other, and are the same as the width dimension of the attachment portion 41 in the in-plane direction.

With the mounting portion 41 attached to the lower overhang plate portion 22, one arm portion 42 holds the heated foamed material 8a (the portion excluding the lower end) of the heated foamed material 8a against the mounting surface 20. Press down in the board thickness direction (toward the indoor side). On the other hand, the other arm portion 43 presses the pressed surface 25 via the heated foaming material 8b. Therefore, in this example, also for the other arm portion 43, the heated foamed material 8b (the portion excluding the upper end portion) is pressed against the pressed surface 25 in the thickness direction of the heated foamed material 8b. In this example, the magnitude of the force with which the arm parts 42 and 43 suppress the heated foamed materials 8a and 8b is as follows: It can be changed depending on the length of the attachment part 41 (upper plate part 44 and lower plate part 45) in the indoor and outdoor directions relative to the dimension to the side surface, and is large enough to lightly touch the outdoor side surface of the heat foaming materials 8a and 8b. From there, the size can be adjusted to the extent that the heated foaming materials 8a, 8b can be pressed strongly.

In order to attach the heated foam material fixture 40 of this example as described above to the lower overhang plate section 22, as shown in FIG. 22 from the outdoor side, and with the outdoor end of the heated foam material fixture 40 tilted diagonally upward, insert the outdoor end of the lower overhang plate part 22 inside the mounting part 41. insert. Thereafter, while moving the lower plate part 45 constituting the mounting part 41 indoors along the lower surface of the lower overhanging plate part 22, the outdoor end of the heating foam fixture 40 is tilted downward. As a result, as shown in FIG. 6(B), the outdoor end of the lower overhang plate section 22 is pushed deep into the attachment section 41. As a result, the heated foam material fixture 40 is attached (attached) to the lower overhang plate portion 22 .

In this example, after the heated foaming material fixture 40 is attached to the lower projecting plate portion 22 in this manner, the airtight piece 12b is engaged with the engagement groove 11b. Therefore, the heated foam material 8b placed above is covered from the outdoor side by the airtight piece 12b. On the other hand, the heated foaming material 8a disposed below is exposed to the outdoors. In addition, the airtight piece 12b locked in the locking groove 11b presses the upper plate part 44 forming the mounting part 41 against the upper surface of the lower projecting plate part 22, and the connection forming the mounting part 41 The portion 46 is pressed against the outdoor end surface of the lower overhang plate portion 22.

In the door device 1 of this example having the above configuration, the heated foamed materials 8a and 8b are not only attached to the lower frame 5 with an adhesive, but also heated using the heated foamed material attachment 40. The foamed materials 8a and 8b are pressed down in the thickness direction. Therefore, it is possible to prevent the heated foaming materials 8a and 8b from falling off the lower frame 5 before foaming. Therefore, in the event of a fire, the foamed (expanded) heated foam material 8a closes the gap between the lower piece (lower stile 34) of the door 3 and the outdoor lower frame substrate part 15 of the lower frame 5 within the plane. It can be blocked along the entire length of the direction. Furthermore, the heated foamed material 8a can also prevent the airtight piece 12b from melting. In addition, when the airtight piece 12b melts, the heated foaming material 8b attached to the pressed surface 25 foams, thereby holding the lower frame of the door 3 (lower frame 34) and the lower frame 5. The gap between the piece 16 can be closed over the entire length in the in-plane direction. Note that the heated foamed material 8b can also be prevented from tilting or falling off from the locking groove 11b by the airtight piece 12b, but in this example, the heated foamed material 8b is Since it is held down by the other arm 43 of the tool 40, even after the airtight piece 12b melts, the posture of the heated foaming material 8b can be stabilized, and the direction of foaming can be regulated to the desired direction. can.

In this example, instead of locking the heated foamed materials 8a and 8b in sheath-shaped grooves formed in the lower frame 5, a heated foamed material attachment 40, which is a separate component from the lower frame 5, is used. The heated foam material 8a, 8b can be installed not only in a new door device 1 but also in an existing door device 1 in order to suppress the door device. That is, as in this example, it becomes possible to attach the heated foam materials 8a and 8b to the lower frame 5 which is not provided with a sheath-like groove.

The mounting surface 20 is provided on the outdoor side surface of the base 18 that constitutes the lower half of the lower frame holding piece 16, and is located near the floor surface. For this reason, even if it is attempted to fix the heated foam material 8a to the mounting surface 20 using, for example, screws, the work space is so narrow that the screwing work itself cannot be performed or the workability becomes poor. On the other hand, in the case of this example, by simply pushing the heated foam material fixture 40 into the lower overhang plate part 22 from the outdoor side, the heated foam material fixture 40 can be attached to the lower overhang plate part 22. The heating foam material 8a can be attached to the surface 20 to be attached. Therefore, according to the structure of this example, restrictions regarding the mounting position of the heated foaming material 8a can be made less likely.

In addition, since the bent portion 47 provided on the attachment portion 41 is engaged with the bent portion 24b provided on the lower overhang plate portion 22 in the indoor and outdoor directions, the heated foam material attachment 40 can It can be prevented from falling off from the lower overhang plate part 22 towards the outdoors. Therefore, even when the pair of arms 42, 43 increases the force of pressing the heated foamed materials 8a, 8b toward the indoor side, the heated foamed material attachment 40 moves toward the outdoor side (falls off). ) can be prevented. Furthermore, the airtight piece 12b locked in the locking groove 11b presses the upper plate part 44 forming the mounting part 41 against the upper surface of the lower projecting plate part 22, and the connecting part 46 forming the mounting part 41 can be pressed against the outdoor end surface of the lower overhanging plate portion 22, so that the posture of the heated foam material fixture 40 can be stabilized. Further, it is also possible to prevent the heated foam material fixture 40 from moving toward the outdoors and from moving in the in-plane direction.

Furthermore, in this example, since the indoor side surfaces of the pair of arm sections 42 and 43 are brought into contact (surface contact) with the outdoor side surfaces of the heated foam materials 8a and 8b, the pair of arm sections 42 and 43 , 43 and the outdoor side surfaces of the heated foamed materials 8a and 8b, it is possible to suppress the heated foamed material fixture 40 from moving in the in-plane direction.

Further, since the lower plate part 45 constituting the mounting part 41 is configured in a flat plate shape, and the upper surface of the lower plate part 45 is brought into surface contact with the lower surface of the lower overhanging plate part 22, the lower plate part The frictional force acting between the upper surface of 45 and the lower surface of lower overhang plate portion 22 can be increased. Therefore, it is possible to effectively suppress movement of the heated foaming material fixture 40 in the in-plane direction.

[Second example of embodiment]
A second example of the embodiment will be described using FIGS. 7 and 8.
In this example, only the shape of the heated foaming material fixture 40a is changed from the structure of the first example of the embodiment. Specifically, the shape of a pair of arm portions 42a and 43a constituting the heated foaming material fixture 40a is changed.

Among the pair of arm parts 42a and 43a, one of the arm parts 42a, which is disposed lower, is configured in a flat plate shape, and in a free state, the arm part 42a extends downward from the indoor end of the lower plate part 45. It extends in the direction towards the indoor side. Therefore, one arm portion 42a extends in a direction closer to the mounting surface 20 as it goes toward the distal end side, and the included angle α with the lower plate portion 45 is an obtuse angle. The lower end of one arm 42a is located closest to the indoor side. In the illustrated example, the included angle α between one arm portion 42a and the lower plate portion 45 is about 95 degrees.

Among the pair of arm parts 42a and 43a, the other arm part 43a disposed above is configured in a flat plate shape, and in a free state, the arm part 43a extends upwardly from the indoor end of the upper plate part 44. It extends in the direction towards the indoor side. Therefore, the other arm portion 43a extends in a direction closer to the pressed surface 25 as it goes toward the distal end side, and the included angle β with the upper plate portion 44 is an obtuse angle. The upper end of the other arm 43a is located closest to the indoor side. In the illustrated example, the included angle β between the other arm portion 43a and the upper plate portion 44 is approximately 115 degrees.

In the case of this example as well, with the attachment part 41 attached to the lower overhanging plate part 22, one arm part 42a attaches the heated foamed material 8a to the mounting surface 20 by the thickness of the heated foamed material 8a. restrain in the direction. In this way, when the heated foaming material 8a is held down by one arm 42a, the attachment part 41 (connecting part 46) does not move toward the outdoors due to the engagement between the bent part 47 and the bent part 24b. As shown in FIG. 8, one arm portion 42a receives a reaction force from the heated foaming material 8a and is elastically deformed in a direction that reduces the included angle α with the lower plate portion 45. As shown in FIG.

Further, with the attachment portion 41 attached to the lower overhang plate portion 22, the other arm portion 43a presses the pressed surface 25 via the heated foam material 8b. That is, also in this example, the other arm portion 43a presses the heated foamed material 8b against the pressed surface 25 in the thickness direction of the heated foamed material 8b. In this way, when the heating foam material 8b is held down by the other arm 43a, the attachment part 41 (connecting part 46) does not move toward the outdoors due to the engagement between the bent part 47 and the bent part 24b. As shown in FIG. 8, the other arm portion 43a receives a reaction force from the heated foaming material 8b and is elastically deformed in a direction that reduces the included angle β with the upper plate portion 44.

In this example, the upper surface of the lower plate section 45 can be elastically pressed against the lower surface of the lower overhanging plate section 22 by using the force that elastically deforms the one arm section 42a. Further, the lower surface of the upper plate portion 44 (lower end portion of the bent portion 47) is elastically pressed against the upper surface of the lower overhang plate portion 22 by using the force that elastically deforms the other arm portion 43a. Can be done. That is, the lower overhanging plate part 22 can be elastically held in the thickness direction (vertical direction) by the upper plate part 44 and the lower plate part 45 that constitute the attachment part 41.

In this example having the above configuration, one arm 42a can elastically press the heated foam material 8a, and the other arm 43a can elastically press the heated foam material 8b. be able to. As a result, the pair of arms 42a, 43a can increase the force with which the heated foaming materials 8a, 8b are held down, so that it is possible to effectively prevent the heating foaming materials 8a, 8b from falling off before foaming. Furthermore, the frictional force that acts between the indoor side surface of one arm 42a and the outdoor side surface of the heated foam material 8a, and the frictional force that acts between the indoor side surface of the other arm section 43a and the outdoor side surface of the heated foam material 8b. It is possible to increase the frictional force that acts between the two. Therefore, it is possible to more effectively suppress movement of the heated foaming material fixture 40a in the in-plane direction.

Furthermore, since the lower overhanging plate part 22 can be elastically held between the upper plate part 44 and the lower plate part 45 that constitute the mounting part 41, it is possible to prevent the heated foam material fixture 40a from moving outdoors. It is also possible to suppress the movement of the heated foaming material fixture 40a in the in-plane direction.
Other configurations and effects are the same as in the first example of the embodiment.

[Third example of embodiment]
A third example of the embodiment will be described using FIGS. 9 and 10.
In this example, only the shape of the heated foaming material fixture 40b is further changed from the structure of the second example of the embodiment. Specifically, the heated foaming material fixture 40b includes a folded portion 48 folded back toward the outdoors at the tip of one arm portion 42a disposed below.

The folded portion 48 has a flat plate shape, and extends downward from the lower end of one arm portion 42a in a direction toward the outdoor side. Therefore, the folded portion 48 extends in a direction away from the mounting surface 20 as it goes toward the distal end side, and the included angle γ with one arm portion 42a is an obtuse angle. In the illustrated example, the included angle γ between the folded portion 48 and one arm portion 42a is approximately 110 degrees.

In this example, the outdoor lower frame substrate part 15 constituting the lower frame 5 is covered with a lower frame cover 49 made of metal such as stainless steel, and the lower frame cover 49 is ) is elastically pressed down from above. However, when carrying out the present invention, the tip of the folded portion may not be in contact with the upper surface of the outdoor lower frame substrate portion 15, or may not be in contact with the lower frame cover 49 (leaving a gap between it and other members). It is also possible to adopt a configuration (provided).

In this example having the above configuration, the tip of the folded part 48 that is folded back toward the outdoors from the tip of one arm 42a is brought into contact with the surface of the lower frame cover 49, so that the heating The foam fixture 40b can be prevented from moving toward the outdoors and in the in-plane direction. Furthermore, movement of the lower frame cover 49 with respect to the lower frame 5 can also be suppressed. In this example, the folded portion 48 is provided only on one arm portion 42a. However, when carrying out the present invention, the folded portion can be provided only on the other arm portion 43a, or may be provided on both one arm portion 42a and the other arm portion 43a. As shown by the broken line in FIG. 10, when the folded part 48 is provided on the other arm part 43a, the folded part 48 extends in a direction away from the pressed surface 25 toward the distal end, and The included angle between the arm portion 43a and the arm portion 43a is an obtuse angle.
The other configurations and effects are the same as the first and second examples of the embodiment.

[Fourth example of embodiment]
A fourth example of the embodiment will be described using FIG. 11.
In this example, a heated foamed material fixture 40c having almost the same shape as the heated foamed material fixture 40b according to the third example of the embodiment is used. This embodiment differs from the third embodiment in that only the heated foaming material 8a is suppressed.

In this example, no heated foaming material is provided inside the locking groove 11b provided in the lower frame holding piece 16. For this reason, in this example, the upper plate part 44a constituting the attachment part 41a is extended indoors, and the other arm part 43a disposed above directly contacts the pressed surface 25 without using the heated foam material. It's pressing.

In this example having the above configuration, the heated foam material fixture 40c moves in the in-plane direction by utilizing the frictional force that acts between the indoor side surface of the other arm portion 43a and the pressed surface 25. It is possible to prevent this from happening.
Other configurations and effects are the same as those in the first, second, and third embodiments.

[Fifth example of embodiment]
A fifth example of the embodiment will be described using FIGS. 12 and 13.
In this example, the shape of the heated foaming material fixture 40d is further changed from the structure of the third example of the embodiment. Specifically, in the heated foaming material attachment tool 40d, the upper plate portion 44b constituting the attachment portion 41b is formed into a flat plate shape. Therefore, the upper plate portion 44b does not include a bent portion (engaging portion) that engages with the lower projecting plate portion 22a.

Further, the lower projecting plate portion 22a provided on the lower frame holding piece 16a is formed into a flat plate shape. For this reason, the lower overhanging plate portion 22a does not have a bent portion at the outdoor end portion that engages with the heating foam attachment 40d.

In this example having the above-described configuration, heating is performed only by elastically sandwiching the lower projecting plate portion 22a in the vertical direction between the upper plate portion 44b and the lower plate portion 45 that constitute the mounting portion 41b. The foam fixture 40d is prevented from moving toward the outdoors (falling off) with respect to the lower overhang plate portion 22a.

In this example, not only the lower plate part 45 but also the upper plate part 44b is configured in a flat plate shape, and the lower surface of the upper plate part 44b is brought into surface contact with the upper surface of the lower overhanging plate part 22a. Therefore, it is possible to ensure a large frictional force acting between the lower surface of the upper plate portion 44b and the upper surface of the lower projecting plate portion 22a. Therefore, even when the bent portion (engaging portion) is omitted from the upper plate portion 44b, movement of the heated foaming material attachment tool 40d toward the outdoors can be sufficiently suppressed.
Other configurations and effects are the same as those in the first, second, and third embodiments.

The structures of the embodiments can be combined as appropriate, as long as no contradiction occurs.

Further, when a folded-back portion is provided at the tip of one arm, the shape of the pushed-back portion is not limited to a flat plate shape, and other shapes may be adopted. In addition, when the other arm presses the pressed surface via another member, other members other than the heat-foamed material (for example, a spacer) may be employed as the other member. Further, when carrying out the present invention, it is not an essential requirement to attach the heated foam material to the surface to be attached (or the surface to be pressed) using an adhesive.

Furthermore, when carrying out the present invention, when providing an engaging part in the mounting part constituting the heated foam fixture, it is not limited to the upper plate part, but can also be provided in the lower plate part or other parts. . Furthermore, the shape of the engaging portion is not limited to the bent shape shown in each example of the embodiment, and other shapes may be adopted as long as the movement (falling off) of the heated foam material fixture can be prevented. Can be done.
