Description

This disclosure relates to building materials.

Conventional mounting structures for heat-foamed materials (mounting components) to building materials include a structure in which the heat-foamed material is placed in a holder portion of a shaped member and secured by caulking, and a structure in which the heat-foamed material is secured to the shaped member with screws (see, for example, Patent Document 1).

JP 2014-109107 A

In structures where the heated foam material is placed on the holder part of the extrusion and secured by caulking, the material can only be secured by caulking near the longitudinal end of the holder part, which limits the installation location of the heated foam material. Furthermore, in structures where the heated foam material is secured to the extrusion by screws, the screws press down on the heated foam material, which can result in deformation or damage to the heated foam material.

The purpose of this disclosure is to provide a fixture with a mounting structure for mounting parts that does not require fastening by caulking and can prevent damage to the mounting parts.

The present disclosure relates to a fixture comprising a fastening member, an attachment part having a fastening member insertion hole with a diameter equal to or larger than the head of the fastening member, and an attachment part to which the attachment part is attached and having a movement restriction part that restricts movement of the attachment part in a first direction and a second direction intersecting the first direction, wherein movement of the attachment part in a third direction different from the first direction and the second direction is restricted by the fastening member inserted into the fastening member insertion hole.

FIG. 10 is a perspective view showing a state in which a screw is inserted into a screw insertion hole of the heated foam material.

The following describes a vertical sliding window 1 as a fixture according to an embodiment of the present disclosure. In the following description, the projection direction is the direction along the depth of the fixture, with the back side in Figure 1 being referred to as the exterior side X1 and the front side being referred to as the interior side X2. The surface along the projection direction may be referred to as the projection surface. The projection direction is the direction along the face of the window surface of the vertical sliding window 1. The surface along the projection direction may be referred to as the projection surface.

As shown in Figures 1 to 3, the vertical sliding window 1 comprises a frame 2 attached to an opening in a building frame, a shoji screen 3 fitted inside the frame 2, a screen door 4, an operator handle 5, a locking mechanism 6, and a heated foam material 71 attached by a heated foam material mounting structure 7. The frame 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of vertical frames 23, 24 into a rectangular shape.

As shown in Figures 2 and 3, the upper frame 21, lower frame 22, and vertical frames 23 and 24 each have a metal frame 211, 221, 231, and 241, and a resin cover 212, 222, 232, and 242.

Metal frames 211, 221, 231, and 241 are installed to cover the visible surface of the opening in the building frame on the exterior side X1. Resin covers 212, 222, 232, and 242 are installed on the inner periphery of the metal frames 211, 221, 231, and 241 on the interior side X2 of the metal frames 211, 221, 231, and 241. The periphery of the screen door 4, which is placed on the interior side X2 of the shoji screen 3, is attached to the inner periphery of the resin covers 212, 222, 232, and 242.

The shoji screen 3 is positioned on the inner periphery of the frame body 2 so that it can be opened and closed. The shoji screen 3 is constructed by fitting a glass panel 35, made of one or more glass plates, inside a rectangular frame body consisting of an upper frame 31, a lower frame 32, and left and right vertical frames 33, 34.

The operator handle 5 is attached to the lower frame 22 of the frame body 2. The operator handle 5 transmits rotational force to the shoji screen 3 via the operating arm 51, thereby allowing the shoji screen 3 to be opened or closed.

As shown in Figures 1 and 2, a pair of stays 36 are provided above and below the shoji screen 3 to support the opening and closing movement of the shoji screen 3. One stay 36 spans between the upper frame 31 and the upper frame 21, and the other stay 36 spans between the lower frame 32 and the lower frame 22.

As shown in Figures 1 and 3, the locking mechanism 6 is mounted on the vertical frame 23 of the frame body 2. As shown in Figure 3, the locking mechanism 6 restricts the opening and closing of the shoji screen 3 by engaging a locking plate 61 extending in the indoor/outdoor direction with a locking pin 62 attached to the vertical frame 33.

As shown in Figures 4 to 6, the heated foam material 71 is attached to the vertical frame 23 by the heated foam material attachment structure 7. The heated foam material attachment structure 7 includes the heated foam material 71 (attachment part), an attachment holder 72 (attachment portion), and a screw 78 (fastening member).

In the following description of the heated foam material mounting structure 7, the indoor-outdoor direction in which the outdoor-side restricting portion 76 and the indoor-side restricting portion 77 of the mounting holder 72 are aligned is referred to as the indoor-outdoor direction D1 (first direction). The thickness direction of the heated foam material 71 through which the screw 78 passes is referred to as the thickness direction D2 (second direction). The thickness direction D2 of the heated foam material 71 is perpendicular to (intersects with) the indoor-outdoor direction D1. The up-down direction of the vertical frame 23 through which the outdoor-side restricting portion 76 and the indoor-side restricting portion 77 of the mounting holder 72 extend is referred to as the up-down direction D3 (third direction). The up-down direction D3 is perpendicular to (intersects with) the indoor-outdoor direction D1 and the thickness direction D2 of the heated foam material 71.

As shown in Figures 4 to 6, the heated foam material 71 is formed in a plate shape and is attached to a mounting holder 72 provided on the vertical frame 23 of the frame body 2. The heated foam material 71 has a screw insertion hole 711 (fastening member insertion hole) with a diameter R1 that is equal to or greater than the diameter R2 of the head 781 of the screw 78. The screw insertion hole 711 penetrates the heated foam material 71 in the thickness direction D2.

The mounting holder 72 includes a base plate 73 that is formed from part of the vertical frame 23 and extends in the vertical direction D3, and an outdoor-side restricting portion 76 and an indoor-side restricting portion 77 that serve as movement restricting portions provided on the projected surface 731 on the inner periphery of the base plate 73. The projected surface 731 on the inner periphery of the base plate 73 forms part of the projected surface 23a of the vertical frame 23.

A screw fixing hole 732 is formed in the projecting surface 731 of the base plate portion 73. A screw 78 inserted into the screw insertion hole 711 of the heated foam material 71 is fastened into this screw fixing hole 732.

The outdoor-side restricting portion 76 and the indoor-side restricting portion 77 restrict movement of the heated foam material 71 placed on the mounting holder 72 in the indoor-outdoor direction D1 (first direction) and in the thickness direction D2 (second direction) of the heated foam material 71. The outdoor-side restricting portion 76 and the indoor-side restricting portion 77 are arranged opposite each other on either side of the heated foam material 71 in the indoor-outdoor direction D1.

The outdoor regulating part 76 is located on the outdoor side X1. The outdoor regulating part 76 has an L-shaped regulating part 761 with an L-shaped cross section, an outdoor protruding piece 762, and a tip protrusion 763.

The L-shaped restricting portion 761 has an outdoor-side movement restricting portion 761a (first-direction movement restricting portion) that rises from the projected surface 731 on the inner periphery of the base portion 73, and a thickness-direction movement restricting portion 761b (second-direction movement restricting portion) that protrudes from the tip of the outdoor-side movement restricting portion 761a toward the indoor-side restricting portion 77. The outdoor-side protruding piece 762 protrudes toward the outdoor side X1 from just before the tip of the outdoor-side movement restricting portion 761a in the protruding direction. The tip projection 763 protrudes from the tip of the thickness-direction movement restricting portion 761b of the L-shaped restricting portion 761 toward the heated foam material 71.

The indoor side restricting portion 77 is located on the indoor side X2. The indoor side restricting portion 77 has an L-shaped restricting portion 771 with an L-shaped cross section and a tip protrusion 773.

The L-shaped restricting portion 771 has an indoor-side movement restricting portion 771a (first-direction movement restricting portion) that rises from the projected surface 731 on the inner periphery of the base portion 73, and a thickness-direction movement restricting portion 771b (second-direction movement restricting portion) that protrudes from the tip of the indoor-side movement restricting portion 771a toward the outdoor-side restricting portion 76. The tip protrusion 773 protrudes from the tip of the thickness-direction movement restricting portion 771b of the L-shaped restricting portion 761 toward the heated foam material 71.

The outdoor movement restricting portion 761a and the indoor movement restricting portion 771a are arranged opposite each other on either side of the heated foam material 71 in the indoor/outdoor direction. As a result, the outdoor movement restricting portion 761a and the indoor movement restricting portion 771a restrict movement of the heated foam material 71 in the indoor/outdoor direction D1 (first direction).

The thickness direction movement restricting portions 761b, 771b are positioned so that both ends of the heated foaming material 71 in the indoor/outdoor direction D1 are sandwiched between them and the base portion 73. As a result, the thickness direction movement restricting portions 761b, 771b restrict movement of the heated foaming material 71 in the thickness direction D2 (second direction).

The screw 78 is inserted into the screw insertion hole 711 of the heated foam material 71 placed on the mounting holder 72 and fastened to the screw fixing hole 732 of the base plate portion 73. By positioning the head 781 of the screw 78 inside the screw insertion hole 711 of the heated foam material 71, the head 781 of the screw 78 becomes caught in the screw insertion hole 711 of the heated foam material 71, thereby restricting movement of the heated foam material 71 in the up-down direction D3 (third direction). Note that Figure 5 shows a state in which the head 781 of the screw 78 is not caught in the screw insertion hole 711.

The procedure for attaching the heated foam material 71 to the mounting holder 72 in the heated foam material mounting structure 7 configured as described above will now be described.

First, as shown in Figure 7, the heated foam material 71 is placed on the mounting holder 72. In this state, the movement of the heated foam material 71 in the indoor/outdoor direction D1 (first direction) and the thickness direction D2 of the heated foam material 71 (second direction) is restricted by the L-shaped restricting portions 761, 771 of the outdoor restricting portion 76 and the indoor restricting portion 77.

Next, the screw 78 is inserted into the screw insertion hole 711 of the heat-foaming material 71 and tightened into the screw fixing hole 732 of the base plate 73. This positions the head 781 of the screw 78 inside the screw insertion hole 711 of the heat-foaming material 71.

As a result, the head 781 of the screw 78 becomes caught in the screw insertion hole 711 of the heated foaming material 71, restricting movement of the heated foaming material 71 in the vertical direction D3 (third direction). That is, the outdoor restricting portion 76 and the indoor restricting portion 77 restrict movement of the heated foaming material 71 in the indoor-outdoor direction D1 (first direction) and in the thickness direction D2 (second direction) of the heated foaming material 71, and the head 781 of the screw 78 restricts movement in the vertical direction D3 (third direction).

This embodiment provides the following advantages. The vertical sliding window 1 of this embodiment includes a screw 78, a heated foaming material 71 having a screw insertion hole 711 with a diameter R2 or greater of the head 781 of the screw 78, and a mounting holder 72 to which the heated foaming material 71 is attached and which has an outdoor-side restricting portion 76 and an indoor-side restricting portion 77 that restrict movement of the heated foaming material 71 in the indoor-outdoor direction D1 and the thickness direction D2 of the heated foaming material 71. Movement of the heated foaming material 71 in the indoor-outdoor direction D1 and in the up-down direction D3, which is different from the thickness direction D2 of the heated foaming material 71, is restricted by the screw 78 inserted into the screw insertion hole 711.

As a result, the outdoor regulating portion 76 and the indoor regulating portion 77 regulate movement of the heated foam material 71 in the indoor-outdoor direction D1 and in the thickness direction D2 of the heated foam material 71, and the screws 78 regulate movement of the heated foam material 71 in the up-down direction D3, eliminating the need to fix the heated foam material 71 by crimping, as was previously required. This avoids the need for complicated crimping work and places no restrictions on the installation position of the heated foam material 71. Furthermore, because the heated foam material 71 is not pressed down by screws, deformation and damage to the heated foam material 71 can be prevented.

Furthermore, the screw insertion hole 711 in the heat-foaming material 71 is equal to or larger than the diameter R2 of the head 781 of the screw 78. Therefore, when attaching the heat-foaming material 71, the screw 78 can be inserted into the screw insertion hole 711, which is equal to or larger than the diameter R2 of the head 781, eliminating the need to precisely position the screw 78. This improves production efficiency. Furthermore, because the heat-foaming material 71 has the screw insertion hole 711, which is equal to or larger than the diameter R2 of the head 781 of the screw 78, the screw fixing hole 732 is exposed and can be visually confirmed even when the heat-foaming material 71 is placed on the mounting holder 72, making the fastening work easier.

In addition, in this embodiment, the outdoor-side regulating portion 76 and the indoor-side regulating portion 77 are configured to include L-shaped regulating portions 761, 771, each with an L-shaped cross section, that are arranged opposite each other with the heated foam material 71 in between. This allows for a simple configuration to more reliably regulate movement of the heated foam material 71 in the indoor-outdoor direction D1 and the thickness direction D2.
