Description

Technical Field

[0001] The present invention relates to a fixture in which a facing material is housed inside a frame body formed by joining a vertical frame and a horizontal frame.

Background Art

[0002] Conventionally, fixtures such as shoji in which a facing material is housed inside a frame made of a frame body formed by joining a vertical frame and a horizontal frame are known. For example, in Patent Document 1, a shoji constituting a sliding window has an upper frame, a lower frame, a meeting frame, and a door end frame framed in a square frame shape to form a frame body, and a multilayer glass is housed inside the frame body. The upper frame and the lower frame of this shoji are framed and fixed by abutting both ends against the meeting frame and the door end frame. A sealer having water absorption is attached to the surface facing the lower frame side of the vertical frame where the end portion on the door end side of the lower frame is joined. And it is said that rainwater that has entered the outdoor side of the door end frame is blocked from moving to the indoor side by filling the gap at the joint between the meeting frame, the door end frame, and the lower frame with a sealer.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Although the gap of the above conventional fixture is filled with a sealer interposed at the joint between the meeting frame, the door end frame, and the lower frame, rainwater and the like that have entered the frame body from the joint between the end portion of the upper frame and the meeting frame and the door end frame are likely to enter the indoor side by passing through the vertical frame, and there is a problem that there is a risk of water leakage into the room through a slight gap or the like.

[0005] The present invention has been made in view of the above conventional problems, and an object thereof is to provide a fixture having higher watertightness.

Means for Solving the Problems

[0006] The main invention for achieving this objective is a joinery in which a facing material is housed inside a frame formed by joining vertical and horizontal frames, wherein the vertical and horizontal frames each have a receiving groove for accommodating the peripheral end of the facing material, a visible surface forming the bottom of the receiving groove, and a restricting projection provided along the longitudinal direction that protrudes from the visible surface into the frame and restricts the movement of water that has entered from the outside into the inside, the restricting projection being provided at a position opposite to the outer peripheral end surface of the facing material, and a drainage hole is provided on the visible surface of the horizontal frame positioned below the facing material, on the outside side of the restricting projection. Other features of the present invention will be made clearer by description in this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide building components with superior watertightness. [Brief explanation of the drawing]

[Figure 2] This is a cross-sectional view of a building component that is an embodiment of the present invention. [Figure 3] This diagram shows the sealing member provided between the vertical frame and the upper and lower frames. [Figure 4] This is an enlarged view of section A in Figure 1. [Figure 5] This is an enlarged view of section B in Figure 2. [Figure 6] This is a perspective view showing the vertical and lower frames in their joined state. [Figure 7] This is an enlarged view of section C in Figure 3. [Modes for carrying out the invention]

[0009] The following description of a building component according to one embodiment of the present invention will be made with reference to the drawings. As an example of the joinery in this embodiment, we will describe a sliding window joinery 1 equipped with an inner sash 2 and an outer sash 3, as shown in Figures 1 and 2.

[0010] In the following explanation, when viewing the door 1 installed in a building, etc., from the interior side, the vertical direction is referred to as the vertical direction, the horizontal direction as the left-right direction, and the depth direction (interior-exterior direction) as the depth direction. Even for each part of the door 1, and even for each component of the door 1 in its individual state, the direction will be specified and explained in terms of the vertical direction, left-right direction, and depth direction when installed in a building, etc.

[0011] As shown in Figures 1 and 2, the joinery 1 includes a window frame 4 that is attached to the building to form an opening, and an inner sash 2 and an outer sash 3 that are supported by the window frame 4 and can slide in the left-right direction.

[0012] The inner sash 2 and the outer sash 3 each have a rectangular double-glazed glass panel 5 as a facing material, and frame bodies 6 and 7 that house the periphery of the double-glazed glass panel 5 and are framed in a rectangular shape. The frame bodies 6 and 7 each have upper frame bodies 61 and 71 and lower frame bodies 62 and 72 as horizontal frames located above and below the double-glazed glass panel 5, and vertical frame bodies 63 and 73 as vertical frames located on the left and right sides.

[0013] The upper frames 61 and 71 are interposed and joined between the upper ends of the vertical frames 63 and 73, which are spaced apart in the left-right direction, and the lower frames 62 and 72 are interposed and joined between the lower ends of the vertical frames 63 and 73. Since the structure of the part that holds the double-glazed glass 5 is the same in the frame body 6 of the inner sash 2 and the frame body 7 of the outer sash 3, the structure of the part that holds the double-glazed glass 5 will be explained here using the inner sash 2 as an example.

[0014] The upper frame 61, lower frame 62, and vertical frames 63 of the frame body 6 are all formed integrally by locking the indoor frame members 61B, 62B, 63B located on the indoor side to the outdoor frame members 61A, 62A, 63A located on the outdoor side. The outdoor frame members 61A, 62A, 63A are extruded members made of aluminum, and the indoor frame members 61B, 62B, 63B are extruded members made of synthetic resin.

[0015] Each of the outdoor frame members 61A, 62A, 63A has accommodation grooves 61C, 62C, 63C for accommodating the peripheral end portions 5A of the multilayer glass 5 on the inner peripheral side in a state of being joined to the frame body 6 in a rectangular shape.

[0016] As shown in FIGS. 1, 4, and 5, each of the accommodation grooves 61C, 62C, 63C has prospective surface portions 61D, 62D, 63D forming the bottom of the groove and the prospective surface, outdoor wall portions 61E, 62E, 63E extending from the outdoor edges of the prospective surface portions on the inner peripheral side, and indoor wall portions 61F, 62F, 63F extending from the indoor edges of the prospective surface portions on the inner peripheral side.

[0017] On the prospective surface portion of the lower frame 62D, at a substantially central position in the prospective direction and at a position facing the outer peripheral end face 5B of the multilayer glass 5 accommodated in the accommodation groove 62C, a regulating projection 62G is provided which projects inward along the longitudinal direction of the lower frame 62. The regulating projection 62G has an extension piece 62H extending outward on the inner peripheral end. The prospective surface portion 62D has a low surface portion 62K which is slightly on the outdoor side of the regulating projection 62G and has a lower height on the indoor side.

[0018] At a substantially central position in the prospective direction of the low surface portion 62K, a screw engaging portion 62I for screwing a screw for joining the lower frame 62 and the vertical frame 63 is provided along the longitudinal direction of the lower frame 62, and the screw engaging portion 62I is provided so as to project upward from the low surface portion 62K. Further, as shown in FIGS. 6 and 7, a drain hole 62J for discharging water that has entered the low surface portion 62K is provided in the low surface portion 62K.

[0019] The drain holes 62J are provided at two locations at appropriate intervals in the longitudinal direction of the lower frame 62. At the locations where the drain holes 62J are provided, a part of the lower surface portion 62K and the screw-threaded engagement portion 62I is cut away. Also, at the position where the drain hole 62J is provided in the longitudinal direction of the lower frame 62, the regulating projection 62G is also cut away. In the present embodiment, an example in which the drain holes 62J are provided at two locations has been described, but the drain holes are not limited to two locations and may be provided as appropriate.

[0020] On the prospective surface portion 63D of the vertical frame 63, as shown in FIG. 5, at approximately the center in the prospective direction, a regulating projection 63G is provided along the longitudinal direction of the vertical frame 63 and protruding inward. The regulating projection 63G has an extension piece 63H extending outward on the outdoor side at the end on the inner peripheral side.

[0021] At the inner peripheral-side end of the outdoor wall portion 63E of the vertical frame 63, a fin portion 63I is provided that slightly protrudes inward and whose indoor-side end extends to the outer peripheral side. At the inner peripheral-side edge of the indoor wall portion 63F of the vertical frame 63, a hook piece 63J provided on the indoor frame member 63B is locked.

[0022] The distance between the outdoor wall portion 63E and the indoor wall portion 63F of the vertical frame 63 is formed to be approximately equal to the width from the outdoor surface of the outdoor wall portions 61E, 62E of the upper frame 61 and the lower frame 62 to the indoor surface of the indoor wall portions 61F, 62F. The ends in the longitudinal direction of the upper frame 61 and the lower frame 62 are inserted and joined between the outdoor wall portion 63E and the indoor wall portion 63F of the left and right vertical frames 63.

[0023] As shown in FIG. 6, the vertical frame 63 has the fin portion 63I at the portion where the upper frame 61 and the lower frame 62 are inserted in the outdoor wall portion 63E and the hook piece 63J locked to the indoor wall portion 63F cut away. For this reason, when the vertical frame 63 is joined to the upper frame 61 and the lower frame 62, the outdoor wall portion 63E of the vertical frame 63 faces and abuts against the outdoor wall portions 61E of the upper frame 61 and 62E of the lower frame 62, and the indoor wall portion 63F of the vertical frame 63 faces and abuts against the indoor wall portions 61F of the upper frame 61 and 62F of the lower frame 62. Incidentally, in FIG. 6, the cut-away portions of the fin portion 63I and the hook piece 63J are shown on the upper end side of the vertical frame 63, but the same applies to the lower end side.

[0024] As shown in Figure 6, sheet-like sealing members 8 and 9 are interposed between the visible surface 63D of the vertical frame 63 and the end faces 62L of the upper frame 61 and lower frame 62. These are joined by screws that enter from the outer circumference of the vertical frame 63 in the left-right direction and are screwed into the threaded portions 61I and 62I of the upper frame 61 and lower frame 62. When the screws are tightened, the sealing members 8 and 9 interposed between the visible surface 63D and the end faces 62L of the upper frame 61 and lower frame 62 are compressed by the end faces 62L of the upper frame 61 and lower frame 62. Note that in the drawing, only the end face 62L of the lower frame 62 is shown, and the end face of the upper frame 61 is omitted from the illustration.

[0025] The sealing members 8 and 9 are made of synthetic resin, such as rubber sheets, and are sized to slightly extend beyond the outer circumference of the end faces 62L of the upper and lower frames 61 and 62. As shown in Figures 6 and 7, the sealing members 8 and 9 are attached to the visible surface portion 63D of the outdoor frame material 63A of the vertical frame 63 by removing the restrictive protrusions 63G in the area facing the end faces 62L of the upper and lower frames 61 and 62, thereby creating a flat visible surface across its entire width, using adhesive or double-sided tape.

[0026] The sealing member 9, which is adhered to the lower side of the vertical frame 63, has a horizontal portion 9D that forms a horizontal surface at a higher position than the portion 9C of the visible surface 62D of the lower frame 62 that faces the end 62L of the outdoor wall portion 62E, between the portion 9A of the lower frame 62 that faces the end 62L of the outdoor wall portion 62E and the portion 9B of the indoor wall portion 62F, and an inclined portion 9E that is provided connected to the outdoor side of the horizontal portion 9D and whose height decreases toward the outdoor side from the horizontal portion 9D. The inclined portion 9E is provided on the outdoor side of the restricting projection 62G of the lower frame 62 in the visible direction, and the outdoor end 9F is located on the outdoor side of the indoor edge 62M of the drain hole 62J.

[0027] In this embodiment, when rain is blown in from the outside, rainwater may seep into the door 1 at the joint between the upper frame 61 and the vertical frame 63, through gaps in the area where the outdoor wall portion 63E of the vertical frame 63 and the outdoor wall portion 61E of the upper frame 61 abut. In this case, even if the infiltrated rainwater seeps along the outdoor wall portion 61E of the upper frame 61 and reaches the visible surface portion 63D of the vertical frame 63, the visible surface portion 63D of the vertical frame 63 is provided with a restricting projection 63G, so the movement toward the indoor side is restricted by the restricting projection 63G, making it difficult for the rainwater to seep into the interior.

[0028] Furthermore, since the restricting projection 63G has an extended piece 63H extending outwards at its inner circumference end, the extended piece 63H acts as a water barrier, making it possible to more reliably suppress rainwater from entering the interior.

[0029] In this case, since the restrictive projection 63G of the vertical frame 63 and the restrictive projection 62G of the lower frame 62, which is located below the double-glazed glass 5, are positioned at approximately the same location in the depth direction, it is possible to easily guide rainwater and other liquids that have been retained on the outdoor side by restricting their intrusion into the indoor side with the restrictive projection 63G of the vertical frame 63 to the outdoor side with the restrictive projection 62G of the lower frame 62.

[0030] Furthermore, since a drain hole 62J is provided on the visible surface portion 62D of the bottom frame 62 located below the double-glazed glass 5, rainwater and the like that are restricted by the restrictive protrusion 62G and kept on the outdoor side of the restrictive protrusion 62G can be discharged through the drain hole 62J without entering the interior. This makes it possible to provide a building component 1 with superior watertightness.

[0031] Furthermore, the upper end of the sealing member 9, which is sandwiched between the lower frame 62 and the visible surface portion 63D of the vertical frame 63 to which the lower frame 62L is joined, is provided with an inclined portion 9E that is lower from the indoor side to the outdoor side than the position of the drain hole 62J in the visible direction. This makes it possible to easily guide rainwater and the like that that has traveled along the vertical frame 63 to the upper end of the sealing member 9 towards the drain hole 62J side by the inclined portion 9E.

[0032] In the above embodiment, a sliding window fitting 1 was used as an example, but the fitting can be any fitting having a structure in which a facing material is housed inside a frame made by joining vertical and horizontal frames, such as a casement window, a sliding window, or a fixed window. Also, although the inner sash 2 of fitting 1 was used as an example, it can be an outer sash or a frame that constitutes a fixed window. Furthermore, the frame is not limited to the frame of a sash, but can be a window frame.

[0033] In the above embodiment, an example was described in which the frame is formed from a composite material having aluminum profiles and synthetic resin profiles. However, the material of the frame can be aluminum only, synthetic resin only, or wood, or any other material that can constitute the frame. Furthermore, although the above embodiment describes an example in which the inner sash 2 and outer sash 3 are equipped with double-glazed glass 5 as the facing material, it is not limited to this, and for example, single-pane glass may also be used, or any facing material whose peripheral edges are housed in a frame to partition the interior and exterior.

[0034] The above embodiments are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.

[0035] This embodiment discloses the joinery described in (1) to (4) below. (1) A joinery in which a facing material is housed inside a frame formed by joining vertical and horizontal frames, wherein the vertical frame and the horizontal frame each have a receiving groove for accommodating the peripheral end of the facing material, a visible surface forming the bottom of the receiving groove, and a restricting projection provided along the longitudinal direction that protrudes from the visible surface into the frame and restricts the movement of water that has entered from the outside into the inside, wherein the restricting projection is provided at a position opposite to the outer peripheral end surface of the facing material, and a drainage hole is provided on the visible surface of the horizontal frame located below the facing material, on the side of the restricting projection that is on the outside.

[0036] In the joinery described in (1), the vertical and horizontal frames have a regulating projection that extends along the longitudinal direction and protrudes inward from the regulating projection to restrict the movement of water to the indoor side, on the bottom of the receiving groove that accommodates the peripheral end of the facing material. Since the regulating projection is located opposite the outer peripheral end surface of the facing material that separates the indoor and outdoor areas, rainwater that has entered the frame on the outdoor side of the facing material on the upper side of the vertical frame is restricted from moving to the indoor side by the regulating projection.

[0037] Furthermore, since drainage holes are provided on the visible surface of the horizontal frame positioned below the panel, on the outdoor side of the restricting projection, rainwater and other liquids that are restricted by the restricting projection and kept on the outdoor side can be discharged through the drainage holes without entering the interior. This makes it possible to provide building components with superior watertightness.

[0038] (2) The joinery described in (1) is characterized in that the restricting projection has an extension piece that extends outward from the inner circumference end.

[0039] In the joinery described in (2), the restricting projection has an extended piece that extends outward from the inner circumference end, so even if rainwater that has penetrated into the frame from the outside through the facing material runs down the restricting projection, the extended piece can prevent it from penetrating into the interior. Therefore, it is possible to provide joinery with even better watertightness.

[0040] (3) In the joinery described in (1) or (2), the restricting projection of the vertical frame and the restricting projection of the horizontal frame located on the lower side of the facing material are arranged in substantially the same position in the depth direction.

[0041] In the joinery described in (3), the restrictive projections of the vertical frame and the restrictive projections of the horizontal frame located on the lower side of the panel are positioned at approximately the same location in the depth direction. Therefore, the restrictive projections of the vertical frame restrict rainwater and other water that has been retained on the outside side by preventing intrusion into the interior can be easily guided to the exterior side of the restrictive projections of the lower horizontal frame.

[0042] (4) In the joinery described in any of (1) to (3), the horizontal frame positioned below the surface material is joined to the vertical frame by sandwiching a sheet-like sealing member between its end and the surface portion of the vertical frame, The upper surface of the sealing member is characterized by having a sloping portion that becomes lower from the indoor side to the outdoor side.

[0043] In the joinery described in (4), the upper surface of the sheet-like sealing member sandwiched between the end of the horizontal frame and the visible surface of the vertical frame to which it is joined has a sloping portion that slopes downward from the indoor side to the outdoor side. This makes it possible to easily draw rainwater and the like that that has traveled down the vertical frame to the upper surface of the sealing member to the outdoor side by the sloping portion. As a result, rainwater and the like that that has traveled down the vertical frame to the upper surface of the sealing member can also be discharged through the drainage hole.
