[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing body and an opening / closing body device provided in an opening of a building, and can be used for a fireproof hinged door such as an entrance door, a fireproof sliding door, and the like.

[0002]

BACKGROUND ART Vent holes are provided in front doors of buildings to ensure air permeability. In addition, entrance doors are required to meet the disaster prevention standards stipulated by building laws in order to prevent smoke from advancing in the event of a fire and to prevent the spread of fire. For this reason, in Japanese Utility Model Publication No. 4-49357, a closing plate is rotatably arranged near the ventilation port, and normally, the closing plate is held at an open position apart from the ventilation port by a thermal fuse so that The ventilation is secured, and when the temperature inside or outside the entrance rises due to a fire or the like, the closing plate urged by a spring closes and turns by melting the temperature fuse so that the ventilation port is closed. Has become.

[0003]

According to this prior art, the closing plate serves as a blocking member for blocking the vent when the temperature rises in the event of a fire or the like, preventing smoke from advancing inside or outside the entrance through the vent, and preventing spread of fire. This blocking structure is a complicated structure in which a spring-biased closing plate is rotatably arranged inside the entrance door, and this closing plate is held in an open position by a thermal fuse. Therefore, there is a problem that a plurality of types of members are required, and it takes time to manufacture.

An object of the present invention is to provide an opening / closing body such as a front door, which can simplify the structure by constructing the structure for blocking the vent hole with a small number of members.

Another object of the present invention is to provide a structure in which, when an opening such as a doorway of an entrance is closed by an opening / closing body such as an entrance door, the structure for closing the opening can be constituted by a small number of members. An object of the present invention is to provide an opening / closing body device that can be simplified.

[0006]

The opening / closing body according to the present invention comprises:
It is an opening and closing body that can be opened and closed in the opening of the building,
Opening and closing having a vent for communicating spaces on both sides of the opening when the opening is closed, and a blocking member for blocking the vent when the temperature of at least one of the spaces rises In the body, the blocking member is a heat-deformable member that is deformed by heating and blocks the vent hole.

According to the present invention, since the blocking member is a heat-deformable member that deforms when heated to block the vent, the block itself blocks the vent when heated, thus It is not necessary to combine a plurality of types of members in order to form a structure that blocks the ventilation port, the types of members can be reduced, the structure can be simplified, and the cost can be reduced.

The heat-deformable member may be any material as long as it deforms when heated and closes the vent hole, for example, a foaming resin, a shape memory alloy, or a heat-expandable gas. It may be a balloon.

When the heat-deformable member is a foamable resin,
This foamable resin is arranged in the vicinity of the vent, and when at least one of the spaces on both sides of the opening closed by the opening / closing body rises in temperature, the foamable resin expands and expands to block the vent. If so, the number of the foamable resin may be one or plural.

However, if two foaming resins are provided and these foaming resins are arranged on both sides of the vent hole, the two foaming resins foam and expand from both sides of the vent hole to be connected to each other when the temperature rises. Therefore, the reliable blocking of the vent hole can be realized with a small number of foaming resins.

The location of the foamable resin is arbitrary as long as it is a location near the vent hole where the vent hole can be closed by foam expansion when the temperature rises. However, the foam resin is a member constituting the opening / closing body. It is more preferable to dispose the surface member facing at least one of the spaces on both sides of the opening closed by the opening / closing member, either directly or indirectly through a surface intermediate member. .

By arranging the foamable resin in this way, when the temperature of the space rises due to the occurrence of a fire or the like, the heat at this time can be transferred to the foamable resin in a large amount and reliably by surface contact. The foaming and expansion of the foamable resin can be effectively performed, and the ventilation port can be reliably blocked.

Further, a horizontal component is provided on the opening / closing body,
When a ventilation port is formed in this component and the ventilation direction is the vertical direction, it is preferable to arrange the foamable resin on the upper part of the horizontal component.

In this case, the horizontal component portion having the vent hole is also used as a foamable resin arranging portion for placing and placing the foamable resin on the opening / closing body. Since it is not necessary to specially provide the arrangement portion, the simplification of the structure of the opening / closing body can be achieved.

In the above, the opening / closing body may be any as long as it is openably / closably provided in the opening of the building and has a vent, for example, it may be an opening door such as an entrance door or an interior door, or a sliding door. It may be a shutter, a shutter curtain of a shutter for a building, or an opening / closing body provided at the entrance of a building like these,
For example, it may be a shoji of a small window for ventilation provided on the wall of the building.

In the case where the opening / closing body is a swing door or a sliding door, the ventilation structure with the ventilation port has a lower portion through which air flows through the lower surface of the door, the inside of the door, and the ventilation means such as a louver device provided on one surface of the door. It may be of an air intake structure, or may be of an upper air intake structure in which air circulates through ventilation means such as a louver device provided on the upper surface of the door and inside the door, and on one surface of the door, or At least one of the left and right end surfaces, the inside of the door, and a ventilation system such as a louver provided on one surface of the door may have a side intake structure in which air flows, and further, both surfaces of the door may be used. A ventilation means may be provided in the air intake structure, and air may be circulated through one of the ventilation means, the inside of the door, and the other ventilation means.

Further, in these air intake structures, for the opening / closing body having a plurality of vent holes through which air passes in order, of these vent holes, for example, only the vent holes close to the space are made of foaming resin or the like. The heat deformable member may be used for blocking, or all the vent holes may be blocked by the heat deformable member.

Further, regarding the opening / closing body provided with a ventilation hole through which air passes in order and a ventilation means such as a louver device, not only the ventilation hole is blocked by a heat-deformable member such as a foaming resin, but ventilation is performed. The ventilating means may also be shut off by providing the means with a shutoff means such as a temperature fuse for shutting off the ventilating means when the temperature rises.

The opening / closing body device according to the present invention comprises an opening provided in a building and an opening / closing body arranged to be openable / closable in the opening. The opening / closing body closes the opening. In the opening / closing body device in which a gap is formed between the facing portion facing the opening / closing body in the member forming the opening and the opening / closing body, at least one of the facing portion and the opening / closing body, A heat-deformable member that is deformed by heating and closes the gap is arranged.

According to this opening / closing body device, even if a gap is formed when the opening of the building is closed by the opening / closing body, when the temperature rises due to fire or the like, the gap is closed due to the deformation of the heat deformable member. Since this gap can be achieved only by disposing the heat-deformable member on at least one of the facing portion of the opening and the opening / closing body, the number of types of members used is reduced and the structure is simplified. Can be realized.

Also in this opening / closing device, the heat-deformable member may be any one as long as it deforms when heated and closes the gap, for example, a foaming resin or a shape memory alloy, or A balloon containing a heat-expandable gas may be used.

However, when the heat-deformable member is made of a foamable resin, advantages such as easy handling and reliable adhesion to a partner can be obtained.

Further, the opening / closing body in this opening / closing body device is also
It may be a hinged door such as an entrance door or an interior door, a sliding door, a rain door, a shutter curtain of a shutter for a building, or an opening / closing body provided at an entrance of a building, for example, on a wall of a building. It may be a shoji with a small window for ventilation provided.

The member forming the opening and having the facing portion facing the opening / closing body may be any member depending on the types of the opening / closing body and the opening, for example, a frame member, or a rail. But it's okay.

Further, in both the opening / closing body and the opening / closing body apparatus according to the present invention, the opening of the building in which the opening / closing body is arranged to be openable / closable has an upper end lower than the ceiling such as an entrance / exit of the entrance. It may also be one that has an upper end that is the same height as the ceiling or a lower end that is the same height as the floor, such as the boundary of the fire-blocking compartment that blocks the adjacent fire-blocking compartments inside the building with the disaster prevention shutter that is an opening / closing body You can use any

Further, the present invention can be applied when the member forming the opening / closing body and the opening is made of any material such as metal or wood, and the kind of the material is not limited. .

A portion of the indoor side surface member 6 corresponding to this opening portion is also opened, and the louver device 4 is arranged in this opening portion, and the louver device 4 is formed to include a front plate 9 and a back plate 10. The upper and lower end portions of the surface plate 9 are joined to the peripheral portions of the opening of the indoor side surface member 6 corresponding to the downward bent portions 8D and the upward bent portions 8E of the ventilation frame 8. The back plate 10 is arranged on the back side of the front plate 9 so as to be slidable left and right by a guide member 11, and the back plate 10 has a long hole formed in the left and right sides of the front plate 9 as shown in FIG. Since the knob 13 which penetrates 12 and protrudes to the indoor side is connected, this knob 1
The back plate 10 can be moved left and right with respect to the front plate 9 by the operation of 3.

As shown in FIG. 2, longitudinal ventilation holes 14 and 15 are formed in the front plate 9 and the rear plate 10,
A plurality of these ventilation holes 14 and 15 are provided at intervals in the left-right direction, and when the back plate 10 is moved left and right by the knob 13 to match the ventilation holes 14 and 15, ventilation can be performed by the louver device 4. When the holes 14 and 15 are displaced, the louver device 4 is closed.

The lower frame 5 of the entrance door 1 has a stepped lower surface portion 5A, and a ventilation hole 16 is formed in this lower surface portion 5A, and a ventilation hole 17 is also formed in the lower surface portion 8B of the ventilation frame 8. Are formed. Therefore, in the entrance door 1, air flows through the lower surface of the entrance door 1, the inside of the ventilation frame 8 which is the inside of the entrance door 1, and the louver device 4 provided on the indoor side surface of the entrance door 1. By doing so, a lower intake structure that allows ventilation between the outdoor space S1 and the indoor space S2 is formed.

As shown in FIG. 3, the lower frame 5
