Description

  The present invention relates to an opening device.

  Conventionally, in an opening device such as a door, there is a case where a plate-like cover material is disposed on the side of the frame that is found (see, for example, Patent Document 1). A frame body having a cover material is higher in design than a hollow frame because a screw or the like for fixing to the opening can be covered with the cover material.

JP 2014-55466 A

  By the way, a high flame barrier performance is required for an opening device such as a door. In the case of an opening device provided with a cover member, the cover member is exposed to the outside, so that it expands more easily than the frame main body in the event of a fire, so there is a gap between the cover member and the main body of the frame member. May occur and fall off the main body. If there is a gap between the cover material and the main body of the frame, or if the cover material falls off from the main body of the frame, the flame shielding performance of the opening device is reduced.

  The present invention has been made in view of the above problems, and provides an opening device having high design performance and high flame shielding performance since a cover material is arranged on the side of the vertical frame where the face is found. For the purpose.

  In order to achieve the above-described object, the present invention provides a left and right vertical frame (for example, a fixed vertical frame 23 on a hanging base side and a fixed vertical frame 24 on a door end side) and an upper and lower horizontal frame (for example, a fixed upper frame described below). 21 and an opening device (for example, a fixed frame body 20 described later) and a door body (for example, a door body 4 described later) fitted into the frame body. For example, an opening device 1 described later, and at least one of the left and right vertical frames and the upper and lower horizontal frames (for example, a fixed vertical frame 23 on the hanging side described later, a fixed vertical frame on the door end side). 24) has a frame main body (for example, fixed vertical frame main bodies 231 and 241 described later) and a cover material (for example, fixed vertical frame cover members 232 and 242 described later) for covering the finding surface of the frame main body. And the end of the frame body in the longitudinal direction is located outside the end of the cover material in the longitudinal direction. Providing an opening device disposed.

  In this invention, the edge part of the longitudinal direction of a frame main body is arrange | positioned rather than the edge part of the longitudinal direction of a cover material at a finding direction outer side. Thus, even if the cover material is heated and extended in the longitudinal direction in the event of a fire, there is a space that allows the cover material to extend between the end of the frame body and the end of the cover material. It becomes difficult to deform. If the deformation of the cover material is suppressed, a gap is generated between the cover material and the frame main body, and the cover material falls off from the frame main body, so that it is possible to suppress a decrease in the flame shielding property of the opening device. Therefore, according to the present invention, since the cover material is disposed, it is possible to provide an opening device having high design performance and high flame shielding performance.

  In addition, at least one of the left and right vertical frames and the upper and lower horizontal frames is a spacer (for example, a spacer 235 described later) that is in contact with a longitudinal end surface of the cover member at a longitudinal end portion of the frame body. 245), and the spacer is preferably configured to allow the cover material to stretch during heating.

  Moreover, it is preferable that the said spacer has the shape fitted to the shape of the edge part of the said frame main body, and is fitted and fixed to the edge part of the said frame main body.

  Moreover, it is preferable that the said spacer has a hole (for example, below-mentioned hole 245b, 245c) penetrated in the longitudinal direction of the said frame main body.

  ADVANTAGE OF THE INVENTION According to this invention, since the cover material is arrange | positioned at the finding surface side of a vertical frame, it can provide an opening apparatus with high flame-shielding performance while having high designability.

Indicates that Specifically, in the case of a vertical frame, the outer side in the direction of finding than the upper end portion means the upper side of the upper end portion, and the outer side of the finding direction than the lower end portion means the lower side of the lower end portion. means. In the case of a horizontal frame, the outer side in the direction of finding than the left end part means the left side of the left end part, and the outer side of the finding direction than the right end part means the right side of the right end part.

FIG. 8 is a plan view of the fixed vertical frame 24, and is a view in which the lid member 246 is removed from the fixed vertical frame 24 as viewed from the arrow Y in FIG. 5. FIG. 8 is an enlarged view of a portion of the fixed vertical frame 24 where the spacer 245 is disposed (attachment portion 241a).
As shown in FIG. 8, the fixed vertical frame cover member 242 is attached to the fixed vertical frame main body 241 (fixed metal vertical frame 243) by engaging the engaging portion 242b with the engaged portion 241b by snap fitting. .
Moreover, as shown in FIG. 8, it has the holes 245b and 245c formed by the inner part 245d. The holes 245b and 245c penetrate in the longitudinal direction of the fixed vertical frame main body 241 (FIG. 6).

The spacer 245 has a shape that fits into the shape of the end of the fixed vertical frame main body 241 (attachment portion 241a), and is fitted into the end of the fixed vertical frame main body 241 and fixed. Specifically, the tip of the extension part 241d of the attachment part 241a is sandwiched from the direction of finding by the pair of extension parts 245e of the spacer 245. In addition, the spacer 245 fitted to the end of the fixed vertical frame main body 241 has the extended portion 245e in contact with the bent portion 241f in the prospective direction, and does not move away from the outdoor side.
The outer end portion of the spacer 245 in the direction in which the inner portion 245d is found contacts the notch portion 241c and the longitudinal direction of the fixed vertical frame main body 241 (direction perpendicular to the paper surface of FIG. 8).

Next, the procedure for assembling and attaching the fixed frame 20 will be briefly described.
First, spacers 235 and 245 are fitted and attached to upper and lower ends of the fixed vertical frame bodies 231 and 241 from the longitudinal direction of the fixed vertical frame bodies 231 and 241. At this time, the notches 231c and 241c are formed in the fixed vertical frame main bodies 231 and 241 so that the spacers 235 and 245 can be easily positioned.
Subsequently, the lid member 246 is arranged and fixed with a screw 247 as a fastening member.

The fixed upper frame cover member 212, the fixed lower frame cover member 222, and the fixed vertical frame cover members 232 and 242 are not assembled, and the screws 151, 152, 153 are inserted into the openings formed in the building. Attach and fix at 154 (FIGS. 3 and 4).
Finally, after attaching the fixed vertical frame cover members 232 and 242, the fixed upper frame cover member 212 and the fixed lower frame cover member 222 are attached.

According to this embodiment, the following effects are produced.
In the present embodiment, the end portions in the longitudinal direction of the fixed vertical frame main bodies 231 and 241 are arranged on the outer side in the finding direction than the end portions in the longitudinal direction of the fixed vertical frame cover members 232 and 242. That is, in this embodiment, the length of the fixed vertical frame main bodies 231 and 241 in the longitudinal direction (height direction) of the fixed vertical frame cover members 232 and 242 is shorter than that of the fixed vertical frame main bodies 231 and 241.
As a result, even if the fixed vertical frame cover members 232 and 242 are heated and extend in the longitudinal direction (height direction) during a fire, the ends of the fixed vertical frame main bodies 231 and 241 and the fixed vertical frame cover members 232 and 242 Since there is a space allowing the extension of the fixed vertical frame cover members 232 and 242 between the ends, the fixed vertical frame cover members 232 and 242 are difficult to deform. If the deformation of the fixed vertical frame cover members 232 and 242 is suppressed, a gap is generated between the fixed vertical frame cover members 232 and 242 and the fixed vertical frame main bodies 231 and 241 so that the fixed vertical frame cover members 232 and 242 are fixed vertically. By dropping from the frame main bodies 231 and 241, it is possible to prevent the flame shielding properties of the opening device from being lowered. Therefore, according to the present embodiment, since the fixed vertical frame cover members 232 and 242 are arranged, it is possible to provide the opening device 1 having high design performance and high flame shielding performance.

Further, in the present embodiment, the fixed vertical frame 23 on the hanging side and the fixed vertical frame 24 on the door end side are in contact with the longitudinal end surfaces of the fixed vertical frame cover members 232 and 242 at the longitudinal end portions. 235,245. In addition, the spacers 235 and 245 are configured to allow the spacers 235 and 245 to extend during heating.
Thereby, the positioning in the longitudinal direction (height direction) of the fixed vertical frame main bodies 231 and 241 of the fixed vertical frame cover members 232 and 242 can be easily performed without reducing the flame shielding properties of the opening device 1. .

Further, in this embodiment, the spacers 235 and 245 have a shape that fits into the shape of the ends of the fixed vertical frame main bodies 231 and 241, and are fitted and fixed to the ends of the fixed vertical frame main bodies 231 and 241.
Thus, the spacers 235 and 245 can be fitted and positioned on the ends of the fixed vertical frame bodies 231 and 241 alone without being pressed by the lid member 246 and screwed. Therefore, the opening device 1 has high workability.

In the present embodiment, the spacers 235 and 245 have holes 245b and 245c that penetrate the fixed vertical frame bodies 231 and 241 in the longitudinal direction.
Thereby, the holes 245b and 245c serve as drain holes. Therefore, the opening device 1 is less likely to collect water in the frame body even during rain, and can suppress corrosion of the resin.
