Description

  The present invention relates to a shoji and joinery, and more particularly to a shoji and joinery provided with three or more face materials.

  2. Description of the Related Art Conventionally, in joinery provided at a position that separates an indoor space from an outdoor space, a multi-layered surface material composed of a plurality of face materials is applied in order to improve heat insulation between the indoor space and the outdoor space. In this type of joinery, a heat insulating space is formed between the glass plates, so that heat can be prevented from entering and exiting through the face material portion. In recent years, in order to further improve the heat insulating properties, joinery using three or more glass plates as the face material of the shoji is also provided. According to such a joinery, the heat insulation space of a plurality of layers is interposed between the room and the outside, so that the effect of suppressing the heat entering and exiting through the face material portion becomes more remarkable (for example, Patent Document 1 and Patent Document 2).

German Patent Application Publication No. 102009012202 JP 2002-61459 A

  By the way, it is necessary to provide eaves members on the four sides of the face material of the shoji so that it can be supported by the opening frame. The eaves member is formed of a metal such as aluminum or a resin, but is a portion that is disposed facing both the room and the outdoors. For this reason, even in a joinery using double glazing as the face material, the eaves member may become a heat bridge and affect heat insulation. In the above-described Patent Document 1 and Patent Document 2, a glass plate positioned outside the outdoor side is also described so as to cover the finding surface facing the outdoor side of the flange member. However, even in such a joinery, since there is heat exchange between the glass plate and the eaves member, the glass plate and the eaves member eventually become a heat bridge, and the heat insulation cannot be improved.

  In order to solve the above-mentioned problem, it is conceivable to provide a flange member on the surface of the face material located on the indoor side. However, when the eaves member is provided on the surface of the face material that is a double-glazed glass, the dimension along the prospective direction of the shoji is greatly increased. In particular, parts such as a handle and a locking device are often provided on the eaves member located at the door tip. For this reason, about the eaves member located in a door tip, the dimension along a prospective direction is often set largely, and it becomes a factor which increases the dimension along the prospective direction of a shoji.

  In view of the above circumstances, an object of the present invention is to provide a shoji and joinery that can further improve the heat insulation without greatly increasing the dimension along the prospective direction.

In order to achieve the above object, the shoji according to the present invention has a rectangular shape having the same outer dimensions, and is joined in a state in which a heat insulating space is secured between each other by interposing a spacer member at the periphery. The first and second face materials and a rectangular member having an outer dimension smaller than that of the first face material, and at least one side end face is located on the same plane, the spacer member on the peripheral portion And a third face material joined to the first face material in a state in which a heat insulating space is secured between the first face material and an end face of the third face material. On the other hand, with respect to the peripheral edge portion from which the end face of the first face member protrudes , the collar member covers only the surface of the first face member, the end face of the third face member, and the surface of the third face member. It is characterized by joining.

  According to this invention, since the heat insulation space is provided on the surface of the eaves member, the heat entering and exiting through the eaves member can be suppressed, and the heat insulation can be improved. In addition, since the flange portion is provided on the surface of the first face member for the peripheral edge portion where the end face of the first face member protrudes from the end face of the third face member, the first face member and the third face member are provided. The dimension along the prospective direction can be reduced by the amount of the heat insulating space secured between the face material and the increase in the dimension along the prospective direction of the shoji can be suppressed.

  According to the present invention, in the above-described shoji, the first face member is joined so that at least an end face located at a door end protrudes beyond the third face member.

  According to this invention, at least at the door end of the shoji, the dimension along the expected direction can be reduced by the amount of the heat insulation space secured between the first face material and the third face material.

  Further, according to the present invention, in the above-described shoji, the first face material has a rectangular shape whose vertical and horizontal dimensions are larger than those of the third face material, and is adjacent to the end face and the door tip located at the door tip. The two end faces are joined so as to protrude from the third face material.

  According to the present invention, the flange member is joined to the surface of the first face member at the three peripheral edges excluding the door butt, and between each of the first face member and the third face member. Therefore, the dimension along the prospective direction can be reduced by the amount of the heat insulation space secured.

  Moreover, the joinery which concerns on this invention was comprised using the shoji in any one of the above-mentioned.

  Also in this invention, since the heat insulation space is provided on the surface of the eaves member, the heat entering and exiting through the eaves member can be suppressed, and the heat insulation can be improved. In addition, since at least the door of the shoji is provided with a flange member on the surface of the first face member, the direction of the heat insulation space secured between the first face member and the third face member is the expected direction. Therefore, it is possible to reduce the dimension along the prospective direction of the shoji.

  According to the present invention, since the heat insulating space is provided on the surface of the eaves member, the heat entering and exiting through the eaves member can be suppressed, and the heat insulation can be improved. In addition, since at least the door of the shoji is provided with a flange member on the surface of the first face member, the direction of the heat insulation space secured between the first face member and the third face member is the expected direction. Therefore, it is possible to reduce the dimension along the prospective direction of the shoji. Furthermore, the first face material, the second face material, and the third face material can be easily assembled on the basis of the end face in the manufacturing process because the end face of the door bottom is located on the same plane. It becomes.
