  The present invention relates to an opening device. In detail, it is related with the opening part apparatus which has the outstanding fire prevention performance.

  In recent years, there has been a demand for further improvement in fire prevention performance for an opening device housed in an opening formed on a wall of a building. For example, in order to improve fire prevention performance, a sliding window is disclosed in which a heating foam material as a refractory material is attached to the door end side of a door sliding door of a shoji (see, for example, Patent Document 1).

JP 2012-136927 A

  However, a steady rest for preventing rattling of the shoji is attached to the side of the shoji door. For this reason, in the case where the heating foam material is attached at a position where the steady rest is attached, it is necessary to newly make a portion to which the heating foam material is attached, such as by cutting out the steady rest.

  Moreover, when attaching a heating foam material to the door-end side of a door-end fence over the upper and lower sides, a heating foam material is affixed avoiding the attachment site | part of a steady rest. Therefore, when the foamed foam material at the part to which the steady rest is attached is peeled off due to deterioration over time, its performance cannot be exhibited in the event of a fire.

  This invention is made | formed in view of the above, The objective is to provide the opening part apparatus which can exhibit the outstanding fire prevention performance even after aged.

  In order to achieve the above object, the present invention uses an upper frame (for example, an upper frame 100 described later), a lower frame (for example, a lower frame 200 described later), and left and right vertical frames (for example, vertical frames 300 and 400 described later). An opening device (for example, a pulling member described later) including a framed frame (for example, a window frame 10 described later) and a shoji (for example, inner pouch 20 and outer pouch 30 described later) accommodated in the frame. A fireproof material (for example, a heating foam material 72a to be described later) is provided on the inner wall surface of at least one of the fences constituting the shoji (for example, door toe walls 24 and 33 to be described later). 71a), and a support portion (for example, support portions 72c and 71c described later) for supporting the refractory material is provided at a position facing the refractory material. .

In the present invention, a refractory material is provided on the inner wall surface of at least one of the cages constituting the shoji. Moreover, the support part which supports a refractory material is provided in the position facing a refractory material.
Thereby, since a refractory material can be supported by the support part provided in the position which opposes a refractory material, even after aging, a fireproof material does not drop out but can exhibit outstanding fireproof performance.

  It is preferable that a steady rest (for example, below-mentioned intermediate steady rest members 62 and 65) is locked to the support portion.

In this invention, the steady rest is locked to the support portion that supports the refractory material.
Thereby, a refractory material can be provided between the inner wall surface of the bag and the support portion at the part where the steady rest is attached. That is, conventionally, when attaching a refractory material at a position where the steady rest is attached, it has been necessary to make a new part for attaching the refractory material by cutting out the steady rest. By using the support part of the material, it is not necessary.

In this invention, a support part is provided in the extension part extended to the outer side in the direction of finding a collar.
Here, a steady rest is usually provided on the outer side in the direction in which the bag is found. Therefore, according to the present invention, the above-described effects are reliably exhibited.

  The upper end portion of the extension portion is in contact with guide rails (for example, guide rails 112 for inner cervical children and guide rails 113 for outer limbs described later) formed on upper rods (for example, upper rods 21, 31 described later). An upper steady rest (for example, upper steady rest members 51 and 52 which will be described later) is provided, and a guide rail formed on a lower collar (for example, lower collars 22 and 32 which will be described later) at the lower end of the extending portion. (For example, the below-mentioned inner rail guide rail 218 and the outer rail guide rail 219 described below are provided with lower steady rests (for example, below-mentioned lower steady rest members 53 and 54). It is preferable that the movement in the vertical direction is restricted by the stopper and the lower swing stopper and is fixed to the heel.

In the present invention, an upper steady rest is provided at the upper end of the extending portion, and a lower steady rest is provided at the lower end of the extending portion. In addition, the upper and lower steady rests regulate the movement of the refractory material in the vertical direction, thereby fixing the refractory material to the eaves.
Thereby, the refractory material provided between the inner wall surface of the bag and the support portion can be fixed by the upper steady rest and the bottom steady rest. Therefore, according to the present invention, it is possible to more reliably avoid the refractory material from falling off after aging, and to exhibit more excellent fire prevention performance.

  The extension portion includes an indoor extension portion (for example, a metal door toe extension portion 331d described later) extending from the indoor side end portion of the fence and a house extending from the outdoor side end portion of the fence. An outer extension portion (for example, a metal door toe extension portion 331c described later), and the steady rest is a buffer member engagement piece (for example, a buffer member engagement) provided in the outdoor side extension portion. It is preferable to fit between the piece 331g), a locking piece (for example, a locking piece 71d described later) provided in the indoor-side extension part, and the support part.

In this invention, the steady rest is fitted between the buffer member engaging piece provided on the outdoor side extending portion, the locking piece provided on the indoor side extending portion, and the support portion.
As a result, the steady rest can be securely fixed in the cage, and in the event of a fire, when the refractory material provided adjacent to the steady rest via the support portion foams, the steady rest is placed outside by the foamed refractory material. And the fitting is released. That is, according to the present invention, since the foaming of the refractory material is not hindered, more excellent fireproof performance can be exhibited.

  The extension portion includes an indoor extension portion (for example, a metal door toe extension portion 331d described later) extending from the indoor side end portion of the fence and a house extending from the outdoor side end portion of the fence. And a resin member (for example, a resin door toe main body 332a to be described later) on the distal end side of the indoor side extension. The steady rest is fitted between the buffer member engaging piece (for example, the buffer member engaging piece 331g) provided in the outdoor-side extension part, the resin member, and the support part. It is preferable to do.

In this invention, the steady rest is fitted between the buffer member engaging piece provided in the outdoor side extending portion, the resin member provided on the distal end side of the indoor side extending portion, and the support portion.
As a result, the steady rest can be securely fixed in the cage, and in the event of a fire, when the refractory material provided adjacent to the steady rest via the support portion foams, the steady rest is placed outside by the foamed refractory material. And the fitting is released. That is, according to the present invention, since the foaming of the refractory material is not hindered, more excellent fireproof performance can be exhibited.

  The refractory material is preferably provided continuously from one end to the other end of the basket.

In this invention, a refractory material is provided continuously from one end to the other end of the bag.
Thereby, at the time of fire occurrence, the gap between the frame and the shoji can be sufficiently filled with the refractory material, and the intrusion of flame can be suppressed. Therefore, according to the present invention, further excellent fire prevention performance can be obtained.
Further, according to the present invention, since the refractory material is continuously provided from one end to the other end of the bag, for example, compared to the case where a plurality of refractory materials are provided so as to avoid the steady state as in the prior art, the number of parts and The number of parts mounting man-hours can be reduced.
