Description

The present disclosure relates to a manufacturing method for a shoji screen and an assembly set for the shoji screen .

Conventionally, a composite structure has been known in which a panel is placed inside a metal frame body with a resin frame material attached to the indoor side of the metal frame (see, for example, Patent Document 1). Such a screen has excellent heat insulation and moisture resistance due to the resin frame material.

JP 2019-203383 A

The frame has a groove for accommodating the end of the panel. The depth of this groove can vary depending on the type of shoji screen. For this reason, in conventional shoji screen structures, it is necessary to prepare metal frame materials and resin frame materials with shapes that correspond to the depth of the groove for accommodating the panel, for each type of shoji screen, which results in a problem of a large number of parts.

The inventor therefore discovered the problem of providing a shoji screen that can reduce the number of parts by forming panel-accommodating grooves of different depths using common parts.

The shoji screen disclosed herein comprises a frame body formed by assembling an upper frame, a lower frame, and a pair of vertical frames, and a panel material placed inside the frame body, and at least one of the upper frame, the lower frame, and the pair of vertical frames is composed of a metal frame material placed on the outside of the room and a resin frame material placed on the inside of the room, and has a panel material housing groove that houses the side end of the panel material, the bottom surface of the panel material housing groove is formed across the metal frame material and the resin frame material, and the visible distance between the side end of the panel material and the innermost end inside the panel material housing groove that faces the side end of the panel material differs between the metal frame material and the resin frame material.

This is a front view of a sliding window with two shoji panels as seen from inside the room. 2 is a longitudinal sectional view taken along line AA in FIG. 1. 2 is a cross-sectional view taken along line BB in FIG. 1. This is an enlarged cross-sectional view of the vertical frame of a shoji screen. A cross-sectional view showing an enlarged view of a vertical frame when the depth of the panel accommodating groove is different. A cross-sectional view showing an enlarged vertical frame of a shoji screen according to another embodiment.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. Figures 1, 2, and 3 show a sliding window 1. The sliding window 1 is constructed by fitting an inner screen 3A arranged on the indoor side, an outer screen 3B arranged on the outdoor side, and a screen door 4 arranged further on the outdoor side of the outer screen 3B, inside a rectangular frame body 2 formed of an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24, so that they can move left and right.

In each diagram, X1 is the exterior side of the sliding window 1, and X2 is the interior side of the sliding window 1. The indoor/outdoor direction along X1-X2 is the projection direction of the sliding window 1. In the sliding window 1, the surface that is arranged along the projection direction is called the projection surface. The direction indicated by X3 is perpendicular to the indoor/outdoor direction, and indicates the projection direction of the sliding window 1.

As shown in Figures 1 and 2, the inner screen 3A has a panel 35 made of two pieces of glass stacked with a spacer between them on the inside of a frame body 30A made of a rectangular frame consisting of an upper frame 31A, a lower frame 32A, a vertical frame on the door front side 33A, and an inner meeting frame 34A, which is a vertical frame on the door rear side. The outer screen 3B has a panel 35 made of two pieces of glass stacked with a spacer between them on the inside of a frame body 30B made of a rectangular frame consisting of an upper frame 31B, a lower frame 32B, a vertical frame on the door front side 33B, and an outer meeting frame 34B, which is a vertical frame on the door rear side.

The inner screen 3A is engaged with the interior rails 211, 221 provided on the upper frame 21 and the lower frame 22, respectively, so that it can move left and right. The lower frame 32A of the inner screen 3A is provided with a door roller 36 that moves along the interior rails 211, 221. The outer screen 3B is engaged with the exterior rails 212, 222 provided on the upper frame 21 and the lower frame 22, respectively, so that it can move left and right. The lower frame 32B of the outer screen 3B is provided with a door roller 36 that moves along the exterior rails 212, 222.

As shown in Figures 2 and 3, the upper frames 31A, 31B, lower frames 32A, 32B, vertical frames 33A, 33B, and inner and outer meeting frames 34A, 34B of the inner and outer screens 3A, 3B each have a composite structure in which resin frames 312, 322, 332, 342 are attached to the indoor side of metal frames 311, 321, 331, 341. This gives the inner screen 3A and outer screen 3B excellent insulation and moisture resistance.

As shown in Figures 2 and 3, the screen 4, which is located on the outside of the outer screen 3B, is engaged so as to be movable in the left-right direction with the screen rails 213, 223, which are located on the outermost sides of the upper frame 21 and lower frame 22, respectively.

Next, we will explain the vertical frames 33A and 33B in more detail. Since the vertical frames 33A and 33B have substantially the same structure, we will explain the structure of the vertical frame 33A of the inner screen 3A below using Figure 4.

The metal frame material 331 of the vertical frame 33A is formed from a metal profile material having a hollow portion 3311 inside. The metal frame material 331 has an exterior wall portion 3312 on the outermost side of the room that protrudes inward in the viewing direction. The exterior wall portion 3312 extends over the entire length of the vertical frame 33A in the extension direction. The exterior wall portion 3312 covers the exterior side surface of the side end portion 35a of the panel 35 that is accommodated in the panel accommodation groove 333 described below.

The interior side surface 331a of the metal frame 331 is provided with an inner circumferential engaging portion 3313 and an outer circumferential engaging portion 3314 for engaging and attaching the resin frame 332. Both the inner circumferential engaging portion 3313 and the outer circumferential engaging portion 3314 have a hook shape and extend over the entire length of the vertical frame 33A in the extension direction.

The resin frame material 332 of the vertical frame 33A is formed from a resin molding material having an inner peripheral hollow portion 3321a and an outer peripheral hollow portion 3321b inside. The inner peripheral hollow portion 3321a and the outer peripheral hollow portion 3321b are arranged side by side in the front direction via a partition wall 3321c extending in the front direction. The resin frame material 332 has an interior wall portion 3322 that protrudes inward in the front direction at the interior side. The tip 3322a of the interior wall portion 3322 is bent toward the exterior side. The interior wall portion 3322 extends over the entire length of the vertical frame 33A in the extension direction. The interior wall portion 3322 covers the interior side of the side end portion 35a of the surface material 35 that is accommodated in the surface material accommodation groove 333 described below.

The exterior surface 332a of the resin frame 332 is provided with an inner engaging portion 3323 and an outer engaging portion 3324 that engage with the inner engaging portion 3313 and the outer engaging portion 3314 of the metal frame 331. The inner engaging portion 3323 and the outer engaging portion 3324 are both hook-shaped and extend over the entire length of the vertical frame 33A in the extension direction.

The distance in the visual direction between the inner circumferential engaging portion 3313 and the outer circumferential engaging portion 3314 of the metal frame material 331 is the same as the distance in the visual direction between the inner circumferential engaging portion 3323 and the outer circumferential engaging portion 3324 of the resin frame material 332. This distance is the same for multiple types of vertical frames with different depths of the panel housing groove 333, which will be described later. The metal frame material 331 and the resin frame material 332 are integrated by the inner circumferential engaging portions 3313, 3323 and the outer circumferential engaging portions 3314, 3324 engaging with each other.

By integrating the metal frame material 331 and the resin frame material 332, the inner hollow portion 3321a of the resin frame material 332 covers the inner engagement portion 3313 of the metal frame material 331 from the inside of the room, and the outer hollow portion 3321b of the resin frame material 332 covers the outer engagement portion 3314 of the metal frame material 331 from the inside of the room. Therefore, the resin frame material 332 covers almost the entire viewing direction of the metal frame material 331 from the inner engagement portion 3313 to the outer engagement portion 3314 of the metal frame material 331 from the inside of the room with the inner hollow portion 3321a and the outer hollow portion 3321b. This further improves the insulation performance of the vertical frame 33A.

When the metal frame material 331 and the resin frame material 332 are integrated, a panel accommodating groove 333 is formed in the vertical frame 33A between the exterior wall portion 3312 and the interior wall portion 3322 to accommodate the side end portion 35a of the panel material 35. The panel accommodating groove 333 is formed by the metal frame material 331 and the resin frame material 332. Therefore, the bottom surface 333a extending in the projection direction of the panel accommodating groove 333 is formed across the metal frame material 331 and the resin frame material 332. Specifically, the bottom surface 333a of the panel accommodating groove 333 is formed by the inner surface 331b of the metal frame material 331 that faces the panel accommodating groove 333, and the inner surface 332b of the resin frame material 332 that faces the panel accommodating groove 333.

When the metal frame material 331 and the resin frame material 332 are integrated, the position of the tip 3312a of the exterior wall portion 3312 of the metal frame material 331 and the position of the tip 3322a in the protruding direction of the interior wall portion 3322 of the resin frame material 332 coincide with the front direction. However, the depth of the surface material accommodation groove 333 along the front direction differs between the metal frame material 331 and the resin frame material 332. Specifically, the inner surface 331b of the metal frame material 331 protrudes inward in the front direction compared to the inner surface 332b of the resin frame material 332. Therefore, the depth D1 from the position of the tip 3312a of the exterior wall portion 3312 to the inner surface 331b of the metal frame material 331 is smaller than the depth D2 from the position of the tip 3322a in the protruding direction of the interior wall portion 3322 to the inner surface 332b of the resin frame material 332.

In this embodiment, the inner surface 331b of the metal frame material 331 and the inner surface 332b of the resin frame material 332 are each flat, so that the inner surface 331b of the metal frame material 331 is the innermost end of the metal frame material 331 at the bottom surface 333a of the panel housing groove 333, and the inner surface 332b of the resin frame material 332 is the innermost end of the resin frame material 332 at the bottom surface 333a of the panel housing groove 333. Therefore, in this vertical frame 33A, the distance in the visible direction between the side end 35a of the panel material 35 and the innermost end facing the side end 35a of the panel material 35 inside the panel housing groove 333 is different between the metal frame material 331 and the resin frame material 332. As a result, a step 333b formed by the metal frame material 331 is formed on the bottom surface 333a of the panel housing groove 333 between the inner surface 331b of the metal frame material 331 and the inner surface 332b of the resin frame material 332.

The side end 35a of the panel 35 can only be inserted into the panel accommodating groove 333 up to the position of the inner surface 331b of the metal frame material 331. Therefore, the depth D1 in the panel accommodating groove 333 is the effective depth of the panel accommodating groove 333, and the depth D2 is the maximum depth of the panel accommodating groove 333. The panel accommodating groove 333 of the vertical frame 33A shown in FIG. 4 can accommodate the side end 35a of the panel 35 up to the effective depth D1. However, because the panel accommodating groove 333 has a maximum depth D2, the step 333b can function as a margin for adjusting the depth of the panel accommodating groove 333. This allows the vertical frame 33A to be provided with a panel receiving groove 333 having an effective depth D1 = D2 by changing the metal frame 331 to a metal frame 331 with a greater depth D1, specifically, a metal frame 331 with a depth D1 equal to the depth D2, without changing the resin frame 332.

Figure 5 shows a vertical frame 33A in the case where a metal frame 331 having a depth D1 equal to the depth D2 of the resin frame 332 is used without changing the resin frame 332 for the metal frame 331 of the vertical frame 33A shown in Figure 4. In the vertical frame 33A shown in Figure 5, when the metal frame 331 and the resin frame 332 are integrated, the position of the tip 3312a of the exterior wall portion 3312 of the metal frame 331 and the position of the tip 3322a in the protruding direction of the interior wall portion 3322 of the resin frame 332 coincide with the expected direction. The distance between the inner circumference side engagement portion 3313 and the outer circumference side engagement portion 3314 of the metal frame 331 shown in Figure 5 is the same as that of the metal frame 331 shown in Figure 4. That is, the positional relationship between the tips 3312a, 3322a, the inner engaging parts 3313, 3323, and the outer engaging parts 3314, 3324 in the vertical frame 33A shown in FIG. 5 is the same as in the case of the vertical frame 33A shown in FIG. 4.

Since D1 = D2 in the vertical frame 33A shown in FIG. 5, no step is formed on the bottom surface 333a of the panel accommodating groove 333 of the vertical frame 33A shown in FIG. 5. Therefore, the panel accommodating groove 333 of the vertical frame 33A shown in FIG. 5 has an effective depth = maximum depth. This allows the vertical frame 33A to have a panel accommodating groove 333 with a greater effective depth than the vertical frame 33A shown in FIG. 4. Since the resin panel material 332 is the same as the resin panel material 332 used in the vertical frame 33A shown in FIG. 4, there is no need to prepare a newly formed resin panel material 332. Therefore, the number of parts required to construct the vertical frame 33A shown in FIG. 5 is reduced.

The vertical frame 33A of this embodiment has inner circumferential engaging portions 3313, 3323 and outer circumferential engaging portions 3314, 3324 that engage with each other across the interior side surface 331a of the metal frame material 331 and the exterior side surface 332a of the resin frame material 332. The distance in the visible direction between the inner circumferential engaging portions 3313, 3323 and the outer circumferential engaging portions 3314, 3324 is the same for multiple types of vertical frames with different depths of the surface material accommodation grooves 333. This allows the metal frame material 331 and the resin frame material 332 to be engaged together even when constructing vertical frames 33A with surface material accommodation grooves 333 of different depths.

The metal frame material 331 of this embodiment has an exterior wall portion 3312 that covers the exterior side of the side end portion 35a of the panel material 35 housed in the panel material housing groove 333, and the resin frame material 332 has an interior wall portion 3322 that covers the interior side of the side end portion 35a of the panel material 35 housed in the panel material housing groove 333. The position of the tip 3312a of the exterior wall portion 3312 and the position of the tip 3322a of the interior wall portion 3322 are aligned in the projection direction. Therefore, when the vertical frame 33A is viewed along the projection direction, the positions of the tips 3312a, 3322a of the exterior wall portion 3312 and the interior wall portion 3322 are aligned, so that the appearance of the shoji screen 3A is not impaired.

In the above embodiment, when changing the effective depth of the panel accommodating groove 333 of the vertical frame 33A, the resin panel material 332 is kept in common and only the metal panel material 331 is changed. However, when changing the effective depth of the panel accommodating groove 333 of the vertical frame 33A, the metal panel material 331 may be kept in common and only the resin panel material 332 may be changed.

Figure 6 shows a vertical frame 33A in which the metal frame 331 is used in common and only the resin frame 332 is changed when changing the effective depth of the surface material accommodation groove 333 of the vertical frame 33A. In this vertical frame 33A, the inner surface 332b of the resin frame 332 protrudes inward in the viewing direction compared to the inner surface 331b of the metal frame 331. Therefore, the depth D1 from the position of the tip 3312a of the exterior wall portion 3312 to the inner surface 331b of the metal frame 331 is greater than the depth D2 from the position of the tip 3322a in the protruding direction of the interior wall portion 3322 to the inner surface 332b of the resin frame 332. As a result, a step 333b that functions as a depth adjustment margin is formed on the bottom surface 333a of the surface material accommodation groove 333. This step 333b is formed by the resin frame material 332.

In the panel accommodating groove 333 of the vertical frame 33A shown in Figure 6, depth D1 is the maximum depth and depth D2 is the effective depth. Therefore, by changing the resin frame 332 to a resin frame with a larger depth D2, specifically, as shown in Figure 5, a resin frame 332 with a depth D2 equal to depth D1, without changing the metal frame 331, it is possible to provide the panel accommodating groove 333 in the vertical frame 33A with an effective depth D1 = D2. In this case, because the metal frame 331 is common, the number of parts required to construct the vertical frame 33A is reduced.

In the above embodiment, the vertical frame 33A on the door end side of the inner screen 3A has been described as an example, but the above configuration can also be applied to the vertical frame 33B on the door end side of the outer screen 3B. Furthermore, although not shown, the above configuration can also be applied to the upper frames 31A, 31B and lower frames 32A, 32B that make up the frame bodies 30A, 30B of the inner screen 3A and the outer screen 3B, in addition to the vertical frames 33A, 33B.

In the above embodiment, a sliding window 1 having an inner screen 3A and an outer screen 3B has been described as an example, but the above configuration can also be applied to, for example, the vertical frame of a sliding window.
