Description

  The present invention relates to a shoji and joinery.

  The joinery is provided with a shoji fold composed of a metal ridge portion on the outdoor side and a resin ridge portion on the indoor side. In this type of shoji, the metal cage part that touches the outdoor air is not exposed indoors, and the heat transfer rate from the metal cage part to the resin cage part is small, so the outdoor temperature is lower than the indoor temperature, for example. In addition, there is no possibility of causing problems such as the occurrence of condensation on the exposed portion of the bag interior (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2006-145503

  In the above-mentioned shoji, the heat insulation can be further improved by increasing the ratio of the resin ridge portion. However, there are cases where a part of the shoji paper bag contains a component for constituting the joinery. For example, in a sliding window shoji equipped with a door, it is necessary that the metal fence portion on the lower side of the lower side has a width (a dimension along the depth direction of the joinery) that can accommodate the door.

  In response to such a requirement, it is possible to provide a shoji that takes heat insulation into consideration by configuring the width of the lower reed so that the door can be accommodated, and configuring the reed to be smaller than this. That is, since the entire ridge can be configured to have the same width by changing the width of the resin ridge portion, the width of the metal ridge portion is set to a different width between the horizontal ridge and the vertical ridge as necessary. It is possible.

  By the way, in the shoji configured as described above, the width of the horizontal metal fence portion is larger than that of the vertical metal fence portion. The edge of the metal ridge portion in the horizontal ridge protrudes from the metal ridge portion. As described above, the horizontal metal hook portion protruding from the vertical hook is covered with the resin hook portion, so that there is no problem during normal use. However, if the resin cage part melts or burns out in the event of a fire, etc., there is a risk that the mouth of the metal cage part on the side will be exposed to the outside and become a through-hole for the flame. In this case, it is not always preferable. In addition, the above-mentioned problem does not occur only when the width of the metal ridge portion in the horizontal plane is larger than the width of the metal ridge portion in the vertical plane. That is, the width of the vertical metal hook part is larger than that of the horizontal metal hook part, and the same problem may occur even in a shoji that has vertical hooks between the horizontal hooks.

  In view of the above circumstances, an object of the present invention is to provide a shoji and a fitting capable of improving heat insulation without impairing fire resistance.

A shoji configured to have a dimension along the prospective direction larger than the metal heel portion of the metal heel portion, and projecting from the locating surface of the metal heel portion in the first directional heel in the fore edge of the metal heel portion in the second directional heel It is characterized by comprising a metal blocking member that covers.

  According to this invention, since the small edge of the metal ridge part in the second direction ridge is covered by the blocking member, the small edge does not become a through-hole even if the resin ridge part is melted or burned out. There is no risk of impairing fire resistance.

  Further, according to the present invention, in the above-described shoji, the blocking member has a flat plate shape and is disposed on a prospective surface facing the small edge of the second direction ridge in the metal ridge portion of the first direction ridge. It is characterized by.

  According to the present invention, since the blocking member can be disposed between the metal rod portion of the first direction rod and the metal rod portion of the second direction rod, it is advantageous in terms of mounting strength.

  According to the present invention, in the above-described shoji, the blocking member is bent from a mounting plate portion disposed along a prospective surface of the metal rod portion in the first direction rod and an edge portion of the mounting plate portion. It has a cover plate portion that extends and covers the edge of the metal ridge portion in the second direction ridge.

  According to this invention, since the blocking member can be attached after connecting the metal hook portion of the first direction hook and the metal hook portion of the second direction hook, the small edge of the metal hook portion in the second direction hook can be surely secured. It becomes possible to cover.

  Further, in the shoji described above, the present invention is configured such that the first direction ridge constitutes a vertical fold extending along the top and bottom, and the metal ridge portion of the second fold is disposed below. A door wheel is provided.

This is advantageous in terms of mounting strength. However, in the present invention, it is not always necessary to apply a flat plate as the blocking member 60. For example, a blocking member having an L-shaped cross section can be applied as in a modification described below. is there.

(Modification)
7, 8 and 9 show shojis 20A and 20B which are modifications of the present invention. The shojis 20A and 20B exemplified here are applied as sliding windows as in the embodiment, and only the shape of the blocking member is different from the embodiment. Hereinafter, the configuration of the blocking member will be described in detail, and the same configurations as those in the embodiment will be denoted by the same reference numerals and detailed description thereof will be omitted.

  As is apparent from the figure, the blocking member 160 of the modified example has a thin plate shape formed of a metal having a melting point higher than that of the aluminum alloy constituting the metal cage portion 22Aa or the like, for example, stainless steel. The mounting plate portion 161 and the cover plate portion 162 are provided. The attachment plate portion 161 is a flat plate-like portion attached to a finding surface facing the interior of the metal rod portions 22Aa and 22Ba in the vertical rods 22A and 22B serving as the door tips. The cover plate portion 162 is a flat plate-like portion that extends from the edge portion of the mounting plate portion 161 toward the room side at a substantially right angle, and faces the interior of the metal rod portions 22Aa and 22Ba in the vertical rods 22A and 22B. It is comprised in the dimension which can cover the fore edge with respect to the metal collar parts 24Aa, 25Aa, 24Ba, 25Ba of the horizontal collars 24A, 25A, 24B, 25B protruding from the finding surface. The blocking member 160 is attached by screws to a finding surface of the metal rod portions 22Aa and 22Ba facing the room through the attachment plate portion 161.

On the other hand, since the blocking member 160 is disposed so as to cover the forehead, the resin ridge portions 22Ab, 22Bb, 24Ab, 25Ab, 24Bb, 25Bb are melted or burned out in the event of a fire or the like. Even in such a case, the state covered with the blocking member 160 is maintained. Thereby, for example, even if combustible gas is generated from the door roller 30 in a high temperature state, it does not leak into the indoor side, and the outer wall portion 26 which is the outdoor side of the metal cage portions 25Aa and 25Ba is melted. However, the small opening does not become a through hole for the flame, which is extremely advantageous in terms of fire resistance.

  Furthermore, according to the modification, it is possible to attach the blocking member 160 even after connecting the vertical rods 22A, 22B and the horizontal rods 24A, 25A, 24B, 25B. Therefore, the edge of the metal flange portions 24Aa, 25Aa, 24Ba, and 25Ba in the horizontal flanges 24A, 25A, 24B, and 25B can be more reliably covered by the cover plate portion 162 of the blocking member 160.

  In addition, in embodiment and the modification which were mentioned above, although shoji 20A and 20B applied to a sliding window are illustrated, this invention is not necessarily restricted to this, A metal cage | basket part of an outdoor side and indoor side It is possible to apply it to others as long as it has a resin ridge portion. In this case, the structure of the horizontal frames 11 and 12 and the vertical frames 13 and 14 which comprise the frame 10 is not restricted to the thing of embodiment. For example, the horizontal frame may be integrally formed of a metal such as an aluminum alloy, as in the vertical frame, or may be a composite type configured of a metal frame portion and a resin frame portion as in the case of the heel. good. Note that the horizontal frame and the vertical frame do not have to have different configurations, and may have the same configuration.

  Moreover, the dimension along the prospective direction of the metal rod portions 24Aa, 25Aa, 24Ba, and 25Ba in the horizontal rods 24A, 25A, 24B, and 25B is larger than the metal rod portions 22Aa and 22Ba in the vertical rods 22A and 22B as the door tips. Although the shoji 20A and 20B are illustrated, this invention is not limited to this, It applies also to the shoji whose dimension along the prospective direction of the metal coffin part in a vertical coffin is large with respect to the metal coffin part of a horizontal coffin.
