Description

[Technical field]

[0001] The present invention relates to a fitting, and more particularly to a fitting configured so that the butt frames of two sliding screens that move on the same rail butt against each other to close. [Background technology]

[0002] Conventionally, there is known a fitting configured so that the butt frames of two shoji screens moving on the same rail butt against each other to close (see, for example, Patent Document 1). The fitting described in Patent Document 1 has a shape in which the butt frame of one shoji screen covers and swallows the outside of the butt frame of the other shoji screen. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3173161 Summary of the Invention [Problem to be solved by the invention]

[0004] When the fittings described in Patent Document 1 have a frame shape in which the butt frame of one shoji screen covers and swallows the outside of the butt frame of the other shoji screen, there is a risk of fingers getting caught between the butt frames when grasping the butt frame with the hand to open or close it.

[0005] Therefore, the object of the present invention is to provide a fitting that does not pose a risk of fingers getting pinched when opening and closing, even if the fitting has a frame shape in which the butt frame of one shoji screen covers and swallows the outside of the butt frame of the other shoji screen. [Means for solving the problem]

[0006] (1) The fitting according to the present invention is a fitting (for example, fitting 1 described later) having a first door (for example, door 5 described later) and a second door (for example, door 4 described later) that move on the same rail (for example, 221 described later), and is configured so that the first door and the second door are closed by butting their butt frames (for example, butt frames 53 and 43 described later), and the butt frame of the first door protrudes toward the interior side in the forward direction, and when the first door and the second door are closed, The second shoji screen has a frame covering portion (e.g., frame covering portion 533 described later) that is arranged to cover the indoor facing surface of the butt frame of the second shoji screen when the second shoji screen is opened (e.g., facing surface 43b described later), and a buffer member (e.g., buffer member 9 described later) is arranged at the location where the frame covering portion of the butt frame of the first shoji screen and the indoor facing surface of the butt frame of the second shoji screen face each other so as to be exposed at the door tip surface of the butt frame of the first shoji screen (e.g., door tip surface 533a described later).

[0007] (2) In the fitting described in (1), it is preferable that the cushioning member is attached to the butt frame side of the first shoji screen.

[0008] (3) In the fitting described in (1) or (2), it is preferable that the buffer member has a hollow portion (for example, hollow portion 93 described later). Effect of the Invention

[0009] According to the present invention, a fitting can be provided that prevents fingers from getting pinched when opening and closing, even if the butt frame of one shoji screen has a frame shape that covers and swallows the outside of the butt frame of the other shoji screen. [Brief description of the drawings]

[Figure 4] 2 is an enlarged cross-sectional view of a butt joint showing a state during opening and closing of a first screen in the fitting shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view showing one embodiment of a fitting according to the present invention, showing the fitting as seen from the indoor side. This fitting 1 is equipped with four shoji screens 3-6 inside a rectangular frame body 2 formed by an upper horizontal frame 21, a lower horizontal frame 22, and a pair of left and right vertical frames 23, 23. Fig. 1 shows a state in which these four shoji screens 3-6 are all closed. The fitting 1 is configured so that by closing the four shoji screens 3-6 in this way, the fitting 1 separates the indoor side from the outdoor side.

[0012] Of the four shoji screens 3 to 6, the two shoji screens 4 and 5 located in the middle are attached to the frame 2 so as to slide left and right on the same rail (not shown) formed on the upper horizontal frame 21 and the lower horizontal frame 22. The two shoji screens 3 and 6 located at both ends are attached to the frame 2 so as to slide left and right on the same rail (not shown) located parallel to the outdoor side of the rail on which the central shoji screens 4 and 5 slide.

[0013] This fitting 1 is closed by butting the shoji screens 3, 6 at both ends against the vertical frames 23, 23, respectively, and by butting the shoji screens 4, 5 arranged on the indoor side of these shoji screens 3, 6 together at the center of the fitting 1. In the closed state, an abutting portion 10 between the shoji screens 4 and 5 is formed in the center of the fitting 1. In this fitting 1, of the two shoji screens 4, 5 arranged in the center, the shoji screen 5 on one side (the right side in Fig. 1) corresponds to the first shoji screen of the present invention, and the shoji screen 4 on the other side (the left side in Fig. 1) corresponds to the second shoji screen of the present invention.

[0014] The shoji screen 4 has glass G housed inside a rectangular frame formed by an upper frame 41 and a lower frame 42 each extending horizontally, a butt frame 43 which is a vertical frame extending vertically on the door end side (right side in Fig. 1) of the shoji screen 4, and a vertical frame 44 which extends vertically on the door trailing edge side (left side in Fig. 1) of the shoji screen 4. The shoji screen 5 has glass G housed inside a rectangular frame formed by an upper frame 51 and a lower frame 52 each extending horizontally, a butt frame 53 which is a vertical frame extending vertically on the door end side (left side in Fig. 1) of the shoji screen 5, and a vertical frame 54 which extends vertically on the door trailing edge side (right side in Fig. 1). The butt frame 43 of the shoji screen 4 in Fig. 1 is hidden by the butt frame 53 of the shoji screen 5, which will be described in detail later, and is not visible. The central shoji screens 4 and 5 are closed by butting their respective butt frames 43, 53 together, and the butt frames 43, 53 butted together in the center form an butt section 10.

[0015] The shoji screens 3 and 6 house glass G inside a rectangular frame formed by upper frames 31 and 61 and lower frames 32 and 62 that extend horizontally, and vertical frames 33, 34, 63 and 64 that extend vertically. In Fig. 1, the vertical frame 33 arranged on the door end side of the shoji screen 3 (right side in Fig. 1) is hidden by the vertical frame 44 of the shoji screen 4 and cannot be seen. Also, the vertical frame 63 arranged on the door end side of the shoji screen 6 (left side in Fig. 1) is hidden by the vertical frame 54 of the shoji screen 5 and cannot be seen. On the indoor and outdoor sides of the vertical frames 34 and 64 of the shoji screens 3 and 6, respectively, handles 35 and 65 for opening and closing are recessed along the extension direction of the vertical frames 34 and 64 (up and down direction in Fig. 1).

[0016] Crescent locks 7, 7 are attached to the vertical middle of the fitting 1, spanning the shoji screens 3 and 4, and the shoji screens 5 and 6, respectively. In addition, auxiliary locking mechanisms 8, 8 are attached to the bottom frames 32, 62 of the shoji screens 3, 6, respectively, for locking the shoji screens 4 and 5.

[0017] Next, the general shape of the shoji screens 4 and 5 and the opening and closing operation of the shoji screen 5 will be described with reference to Fig. 2. Fig. 2 is a schematic diagram for explaining the opening and closing operation of the fitting 1, and shows the shoji screens 3 to 6 in a plan view. In Fig. 2, the illustration of the two rails along which the shoji screens 3 to 6 slide is omitted. The butt frame 43 arranged on the door end side of the shoji screen 4 is formed in a shape that protrudes toward the outdoor side in the projection direction (the indoor / outdoor direction, the up-down direction in Fig. 2). Specifically, the butt frame 43 protrudes in a substantially vertical direction toward the outdoor side, and the protruding portion is formed in a shape displaced toward the shoji screen 5 so as to cover the outdoor-side visible surface 53b (see Fig. 3) of the butt frame 53 of the shoji screen 5.

[0018] The vertical frame 44 on the end side of the shoji screen 4 is formed in a shape that protrudes toward the indoor side in the front direction. Specifically, the vertical frame 44 protrudes in a substantially vertical direction toward the indoor side, opposite to the butt frame 43. This vertical frame 44 is positioned so as to overlap the vertical frame 33 of the shoji screen 3, thereby concealing the vertical frame 33 of the shoji screen 3 from the indoor side.

[0019] On the other hand, the butt frame 53 arranged on the door end side of the shoji screen 5 is formed in a shape that protrudes toward the indoor side in the front direction, opposite to the butt frame 43 of the shoji screen 4. Specifically, the butt frame 53 protrudes so as to protrude in a substantially vertical direction toward the indoor side, and the protruding portion is formed in a shape displaced toward the shoji screen 4 so as to cover the indoor side visible surface 43b (see FIG. 3) of the butt frame 43 of the shoji screen 4.

[0020] The vertical frame 54 on the end side of the shoji screen 5 is also formed in a shape that protrudes toward the indoor side in the front direction, similar to the butt frame 53. Specifically, the vertical frame 54 protrudes so as to protrude in a substantially vertical direction toward the indoor side, similar to the butt frame 53. The vertical frame 54 of the shoji screen 5 is positioned so as to overlap the vertical frame 63 of the shoji screen 6, thereby covering and concealing the vertical frame 63 of the shoji screen 6 from the indoor side.

[0021] When opening and closing the shoji screen 5 from inside the house, the butt frame 53 of the shoji screen 5 that protrudes inside the house is grasped by hand and slid in the direction of the outlined arrow. In other words, the sliding movement of the shoji screen 5 is performed by grasping the butt frame 53 by hand.

[0022] Next, a more specific configuration of the butt frames 43, 53 of the shoji screens 4, 5 will be described with reference to Fig. 3. Fig. 3 is an enlarged cross-sectional view of the butt portion 10 between the shoji screens 4 and 5 in the fitting 1 shown in Fig. 1. In Fig. 3, the shoji screens 4 and 5 are arranged so as to be slidable on the same rail 221.

[0023] The butt frame 43 of the shoji screen 4 is extruded from a metal material such as aluminum, and houses three pieces of glass G spaced apart by spacers S, via a gasket 4a. The butt face 43a of the butt frame 43 (the face that butts against the shoji screen 5) has an integral standing wall 431 that rises almost vertically toward the shoji screen 5. The visible face 43b on the indoor side of the butt frame 43 is covered with a resin cover 432. This gives the shoji screen 4 excellent heat insulation.

[0024] The butt frame 43 has an integral frame covering portion 433 that protrudes toward the outdoor side. The frame covering portion 433 is formed along the extension direction of the butt frame 43 (the up-down direction in FIG. 1). The frame covering portion 433 integrally comprises a first wall portion 433a which rises approximately perpendicular to the surface of the glass G of the shoji screen 4 (the outdoor side surface of the glass G), a second wall portion 433b which bends from the outdoor side end of the first wall portion 433a toward the shoji screen 5 side and extends approximately parallel to the surface of the glass G of the shoji screen 4, a third wall portion 433c which bends from the end of the second wall portion 433b toward the shoji screen 5 side and extends approximately parallel to the first wall portion 433a, and a fourth wall portion 433d which extends from the end of the third wall portion 433c toward the butt surface 43a, and is formed into an approximately rectangular cross section.

[0025] The surface of the second wall portion 433b forms the outdoor facing surface of the butt frame 43 and the frame covering portion 433. This second wall portion 433b protrudes further toward the shoji 5 side than the butt face 43a of the butt frame 43. The second wall portion 433b extends farther toward the shoji 5 side than the butt face 43a, and substantially covers and conceals the entire outdoor facing surface 53b of the butt frame 53 of the shoji 5. As a result, the outdoor side of the butt frame 43 is displaced toward the shoji 5 side. Therefore, when the fitting 1 is observed from the outdoor side, the width of the butt portion 10 is substantially narrow, being only the width of the facing surface of the butt frame 43 of the shoji 4 (the width of the second wall portion 433b), improving the design of the fitting 1.

[0026] On the other hand, the butt frame 53 of the shoji screen 5 also houses three pieces of glass G spaced apart by spacers S, via a gasket 5a. The outdoor-side facing surface 53b of the butt frame 53 extends further toward the shoji screen 4 than the butt face 53a, and overlaps with the standing wall portion 431 formed on the butt face 53a of the butt frame 43 of the shoji screen 4. A first airtight material 531 is attached to the tip of the extended facing surface 53b, sealing the space between it and the standing wall portion 431.

[0027] Furthermore, the butt frame 53 has a frame covering part 533 that protrudes toward the indoor side at the indoor end of the butt surface 53a via a bridge part 532 for heat insulation. The frame covering part 533 is connected to the bridge part 532 and is composed of a frame covering part main body 534 that is integrally extruded from a metal material such as aluminum, and a resin cover 535 that covers the outside of the frame covering part main body 534.

[0028] The frame covering portion main body 534 is integrally formed with a first wall portion 534a which rises approximately perpendicular to the surface of the glass G of the shoji screen 5 (the indoor surface of the glass G), a second wall portion 534b which bends from the outdoor end of the first wall portion 534a toward the shoji screen 4 side and extends approximately parallel to the surface of the glass G of the shoji screen 5, a third wall portion 534c which bends from the shoji screen 4 side end of the second wall portion 534b toward the outdoor side and extends approximately parallel to the first wall portion 534a, a fourth wall portion 534d which bends from the outdoor end of the third wall portion 534c toward the shoji screen 5 side and extends approximately parallel to the second wall portion 534b, and a fifth wall portion 534e which bends from the shoji screen 5 side end of the fourth wall portion 534d toward the outdoor side and is connected to the bridge portion 532.

[0029] Of these, the second wall portion 534b protrudes further toward the shoji 4 side than the abutment surface 53a of the butt frame 53. The second wall portion 534b extends largely parallel to the surface of the glass G toward the shoji 4 side, and substantially covers and conceals almost the entirety of the resin cover 432 that constitutes the outdoor-facing visible surface 43b of the butt frame 43 of the shoji 4. This gives the butt frame 53 a shape that is displaced toward the shoji 4 side. The resin cover 535 of the butt frame 53 covers the outside (indoor side) of the first wall portion 534a, the second wall portion 534b, and the third wall portion 534c. Therefore, when the fitting 1 is observed from the indoor side, the width of the butt joint 10 is narrow, as shown in Fig. 1, substantially the width of the visible surface of the butt frame 53 of the shoji screen 5 (the indoor surface of the resin cover 535), improving the design of the fitting 1. In addition, by having the resin cover 535, the shoji screen 5 has excellent heat insulation properties.

[0030] A second airtight material 536 is housed in the abutting surface 53a of the abutting frame 53, and seals the gap between the abutting surfaces 43a, 53a of the abutting frames 43, 53.

[0031] A large space 100 is provided between the fourth wall portion 534d and the resin cover 432 of the butt frame 43 of the shoji screen 4. This space 100 is provided at a location where the frame covering portion 533 of the butt frame 53 of the shoji screen 5 faces the indoor-side visible surface 43b of the butt frame 43 of the shoji screen 4. Specifically, this space 100 is large enough for a finger to be inserted when gripping the frame covering portion 533 when opening or closing the shoji screen 5.

[0032] A buffer member 9 made of an elastic material such as rubber is provided in this space 100. The buffer member 9 in this embodiment is attached to the outdoor surface of the fourth wall portion 534d of the frame covering portion 533 so as to protrude toward the indoor surface 43b of the butt frame 43. The buffer member 9 extends approximately parallel to the door tip surface 533a arranged on the shoji 4 side of the frame covering portion 533, and has a side portion 91 arranged approximately flush with the door tip surface 533a. Therefore, the buffer member 9 is arranged in the space 100 so as to be exposed on the door tip surface 533a toward the shoji 4 side (left side in FIG. 3). Since the side portion 91 is approximately flush with the door tip surface 533a, it functions to block the space 100 when the shoji 4 and 5 are closed, as shown in FIG. 3. Therefore, there is no risk of impairing the design of the butt portion 10 from the indoor side.

[0033] 3, the cushioning member 9 has an integral protruding piece 92 that comes into contact with the indoor-side visible surface 43b (resin cover 432) of the butt frame 43 when the screens 4, 5 are closed. This allows the cushioning member 9 to function as a third airtight material that seals the gap with the indoor-side visible surface 43b of the butt frame 43.

[0034] Furthermore, the cushioning member 9 has a hollow portion 93. Therefore, the cushioning member 9 has excellent shape retention due to the air in the hollow portion 93, and does not impair the design, and when an external force is applied, the hollow portion 93 (air) is compressed, so that the cushioning member 9 can be deformed with appropriate elasticity (cushioning properties).

[0035] As shown in FIG. 4, when the butt frame 53 of the shoji screen 5 having the buffer member 9 is grasped by hand to open or close the screen, the fingertips come into contact with the side surface 91 of the buffer member 9. At this time, the buffer member 9 allows the opening / closing operator to easily recognize that the fingertips are resting on the side surface 91 of the buffer member 9 (not in a position where the fingers will be pinched). Therefore, when the shoji screens 4, 5 are closed while grasping the butt frame 53, it is possible to prevent the fingers from being pinched between the butt frame 53 and the visible surface 43b on the indoor side of the shoji screen 4. In addition, even if the fingers of the opening / closing operator come too close to the visible surface 43b on the indoor side of the shoji screen 4, the buffer member 9 easily elastically deforms, so there is no risk of hurting the fingers, and operability is improved.

[0036] The cushioning member 9 may be attached to the visible surface 43b on the indoor side of the shoji screen 4; however, when attached to the butt frame 53 side of the shoji screen 5 as shown in this embodiment, the cushioning member 9 is not exposed to the indoor side when the shoji screen 4 or 5 is opened, and is not directly visible from the indoor side, thereby further improving the design of the fixture 1.

[0037] The sliding screens 3 and 6 arranged at both ends of the fitting 1 shown in Fig. 1 may be immovably fixed to the frame 2. Furthermore, the number of sliding screens of the fitting 1 in the present invention is not limited to four, and it is sufficient that at least two sliding screens are butted together to be closed.
