Description

[Technical Field]

[0001] The invention disclosed in this application relates to a fitting frame structure for fittings having a frame body and a shoji screen attached to the frame body so that the shoji screen opening and closing device is attached to the frame body. [Background technology]

[0002] In recent years, in order to save energy, there has been an increasing number of examples of installing highly insulating resin fittings in window openings in buildings. In this type of resin fittings, the frame material that makes up the perimeter of the window frame and the frame material that makes up the perimeter of the shoji screen are often made from extruded hard resin. Metal-resin composite sashes are also known, in which the outdoor portion of the window frame is made from aluminum alloy or the like, and the indoor portion is made from hard resin, with the two connected by a layer of insulating resin sandwiched between them.

[0003] When this type of resin fitting is, for example, a vertical sliding window, the operator handle used to open and close the shoji screen is usually installed on the bottom frame of the window frame. The installation location must be strong enough to reliably fix the base (base part) that rotatably holds the handle and firmly withstand the external forces that occur when opening and closing the window.

[0004] However, window frames made of resin are often formed by using extruded shapes with the same cross-sectional shape for the top frame, bottom frame, and left and right vertical frame members, which are joined at their four corners. Therefore, using a member with a large cross-sectional shape only for the bottom frame member to ensure the installation strength of the operator handle is uneconomical, and joining the four corners is also troublesome. Therefore, Patent Document 1 discloses a window frame structure in which a metal reinforcing member is attached to the resin bottom frame member to reinforce the installation location of the operator handle. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-113843 Summary of the Invention [Problem to be solved by the invention]

[0006] In the fitting frame structure disclosed in Patent Document 1, each frame member constituting the four periphery of a resin frame body has a frame main body portion arranged to face the outer periphery of a shoji screen, and an out-of-plane facing portion protruding from the frame main body portion toward the inside of the frame and facing the interior side of the shoji screen when it is closed. The out-of-plane facing portion has an out-of-plane facing hollow portion that communicates along the longitudinal direction, and a metal out-of-plane facing reinforcement member is disposed within the out-of-plane facing hollow portion. A metal mounting member for attaching an operator handle is attached to the inner periphery of the out-of-plane facing portion and is configured to be fixed to the out-of-plane facing reinforcement member with a screw member or the like.

[0007] By adopting this configuration, a metal mounting member located on the inner periphery of the out-of-plane facing portion is fixed to a metal out-of-plane facing reinforcing member located in the out-of-plane facing hollow portion of the frame material, thereby ensuring high strength at the installation location of the operator handle, and since each frame material is connected to form a flat surface when viewed from the indoor side, a desirable design is obtained.

[0008] However, in the conventional door and window frame structure, metal out-of-plane facing reinforcing members are inserted into the out-of-plane facing hollow sections formed so as to communicate along the longitudinal direction of the frame material, and metal mounting members are placed on the inner periphery of the out-of-plane facing hollow sections, and these two types of metal members are joined with screws, etc. Therefore, it is not easy to align the metal members placed inside and outside the frame material with each other, and the assembly work is time-consuming. In addition, the cross-sectional shapes of the two types of metal members are complex, so their manufacture is also costly.

[0009] The invention disclosed in this application was conceived to improve on this point, and aims to provide a fitting frame structure that, when installing an operator handle or other opening and closing device in a frame body formed of synthetic resin or the like, allows for easy assembly of reinforcing materials to reinforce the installation location with a simple component configuration and rational fit. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the invention disclosed in this application is a fitting comprising a frame body formed by framing a plurality of frame members, a shoji screen attached to the frame body and opened and closed on the outdoor side of the frame body, and an opening and closing device installed on the indoor side of at least one of the plurality of frame members, and employs the following configuration as a fitting frame structure in which a reinforcing material is attached to the visible surface on the inner side of the frame member on which the opening and closing device is installed.

[0011] [1] The reinforcing material is formed to a length that matches the opposing distance between a pair of intersecting frame materials that intersect the frame material on which the opening and closing device is installed and are respectively joined to both ends of the frame material, and screw receiving portions are provided on both end faces of the reinforcing material, so that both end faces of the reinforcing material are respectively abutted against the inner projected faces of the two intersecting frame materials, and by passing screws through the inner projected faces of the two intersecting frame materials from the outside of the frames of the two intersecting frame materials and fastening them to the screw receiving portions, the reinforcing material is fixed between the two intersecting frame materials while attached to the inner projected faces of the frame material on which the opening and closing device is installed, and the base portion of the opening and closing device is connected to the reinforcing material.

[0012] [2] The frame material on which the opening and closing device is installed is an extruded shape made of synthetic resin that has a frame main body portion that is positioned so as to face the outer periphery of the shoji screen when the shoji screen is closed, and an indoor side protruding portion that protrudes from the indoor side to the inside of the frame further than the closed position of the shoji screen in the frame main body portion and faces the visible surface of the frame body of the shoji screen when the shoji screen is closed, and the reinforcing material is attached to the visible surface on the inside of the frame at the indoor side protruding portion.

[0013] [3] The reinforcing material is a metal extruded profile having a groove-shaped cross-sectional shape that opens toward the outside, and the screw receiving portion is a screw hole formed at two corners of the groove-shaped cross-sectional shape.

[0014] [4] A synthetic resin cover material having an L-shaped cross section is placed over the indoor side and the frame side of the reinforcing material, and the opening and closing device is connected to the reinforcing material from the indoor side of the cover material, sandwiching the cover material between them. [Effects of the Invention]

[0015] The door frame structure constructed as described above allows for easy and strong attachment of reinforcing members to the frame members that make up the frame body, thanks to its simple member configuration and rational fit. By connecting the opening and closing device to the reinforcing members, the installation strength of the opening and closing device can be sufficiently ensured. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is an enlarged partial front view showing the lower frame portion of the vertical sliding window. [Figure 3] FIG. 2 is a partial vertical cross-sectional view showing the vertical sliding window with the intermediate portion of the AA cross section omitted. [Figure 4] FIG. 2 is a partial cross-sectional view showing the vertical sliding window with a portion of the BB cross section omitted. DETAILED DESCRIPTION OF THE INVENTION

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 4 show the main parts of a fitting that employs the fitting frame structure of the present invention.

[0018] A fitting 1 to which the invention disclosed in this application is applicable is basically configured to include a frame body 2 formed by framing multiple frame materials, a shoji screen 3 that is attached to the frame body 2 and opened and closed, and an opening and closing device 4 used to open and close the shoji screen 3. The fitting 1 shown as an example is a vertical sliding window in which the shoji screen 3, attached to the vertically long rectangular frame body 2 via a link mechanism (joint arm) 5, is opened and closed to the outdoor side by operating the opening and closing device (operator handle) 4 installed on the indoor side of the lower frame material.

[0019] The lower frame member 21, upper frame member 22, and left and right vertical frame members 23, 24 that make up the four sides of the frame body 2 are all manufactured by extrusion molding of synthetic resin material and have the same cross-sectional shape. In the illustrated embodiment, the four frame members are joined by butting together the ends cut at a 45-degree angle in a "stop" shape.

[0020] Similarly, the frame 31 surrounding the four sides of the shoji screen 3 is formed by joining frame materials with the same cross-sectional shape manufactured by extrusion molding of synthetic resin material. A face material 32 made of triple glass is fitted inside the frame 31. However, the invention disclosed in this application does not particularly limit the detailed configuration of the shoji screen 3.

[0021] In the opening and closing device 4, a base 42 that rotatably holds a handle 41 is attached to a metal reinforcing member 6 that is attached to the inner frame surface of the lower frame member 21. The essential part of the invention disclosed in this application is the structure in which the reinforcing member 6 is attached to the lower frame member 21, and this point will be explained in detail below.

[0022] In the following, when explaining the positional relationships of parts and components and the direction of operation, the up-down direction (height direction) and left-right direction (width direction) will be specified based on the state of the fitting 1 as seen from the indoor side (Figure 1). Also, the direction perpendicular to the opening surface of the fitting 1 will be referred to as the indoor-outdoor direction (depth direction), and the center side within the opening surface of the fitting 1 will be referred to as the inner side of the frame, and the outer periphery side (wall side) will be referred to as the outer side of the frame.

[0023] Each frame member (21 to 24) that constitutes the frame body 2 has a frame main body portion 201 that faces the outer periphery of the frame body 31 of the shoji screen 3 when the shoji screen 3 is closed, an outdoor side protrusion portion 202 that extends to the outdoor side of the frame main body portion 201 and protrudes outside the frame in a roughly stepped manner, and an indoor side protrusion portion 203 that protrudes from the indoor side to the inside of the frame further than the closed position of the shoji screen 3 in the frame main body portion 201 and faces the visible surface of the frame body 31 when the shoji screen 3 is closed.

[0024] The frame body 201 and the outdoor projection 202 are provided with a plurality of hollow spaces communicating in the longitudinal direction of the material, and a plurality of partition walls separating them. However, the invention disclosed in this application does not particularly limit the detailed shapes of the hollow spaces and partition walls. On the indoor-facing surface of the frame body 201, a partition piece 204 that covers the abutment point with the frame material 7 is provided to protrude toward the indoor side.

[0025] In the illustrated embodiment, the indoor-side projection 203 has a hollow, substantially square cross section and is formed integrally with the frame main body 201, with its indoor-side visible surface 203a continuing to the indoor-side visible surface 201a of the frame main body 201. The indoor-side visible surface 203a of the indoor-side projection 203 protrudes slightly inward of the frame beyond the frame-side visible surface 203b. In addition, near the connection between the frame-side visible surface 203b of the indoor-side projection 203 and the outdoor-side visible surface 203c, a lipped groove 203d that opens to the outdoors is formed, and a water-stopping material 205 that seals the gap with the shoji screen 3 is fitted into this groove 203d.

[0026] The reinforcing member 6 is, for example, an extruded member made of an aluminum alloy or other metal material. The reinforcing member 6 in the illustrated embodiment is a member in which a bottom surface portion 61, an upright surface portion 62, and a top surface portion 63 are continuous to form a groove-shaped (C-shaped) cross section. Screw holes (tapping holes) 64 with a substantially C-shaped cross section are formed in two corners of the groove-shaped cross section, and these screw holes 64 form the "screw receiving portion" described in the claims.

[0027] The reinforcing material 6 is placed on the indoor side protruding portion 203 with its bottom surface 61 overlapping the frame-inside visible surface 203b of the indoor side protruding portion 203 of the lower frame material 21, its upright surface 62 aligned with the protruding portion of the indoor side visible surface 203a of the indoor side protruding portion 203, and its groove-shaped opening facing the outdoors. In this state, the bottom surface 61 of the reinforcing material 6 may be temporarily fixed to the frame-inside visible surface 203b of the indoor side protruding portion 203 with adhesive or double-sided tape.

[0028] The reinforcing material 6 is cut so that its length (left-right width as viewed from the indoor side) matches the opposing distance (strictly speaking, the opposing distance between the frame-inside visible faces 203b, excluding the protrusion height of the indoor-side visible faces 203a of the left and right vertical frame members 23, 24) of a pair of vertical frame members 23, 24 (the "intersecting frame members" described in the claims) that intersect the bottom frame member 21 and are joined to both left and right ends of the bottom frame member 21. Then, both end faces of the reinforcing material 6 abut against the frame-inside visible faces 203b of the indoor-side protruding portions 203 of the left and right vertical frame members 23, 24, respectively.

[0029] The left and right vertical frame members 23, 24 have screw insertion holes 206 formed therein that penetrate from the outside of the frame main body 201 to the frame-inside projecting surface 203b of the indoor-side projecting portion 203. Screws 65 are inserted into the screw insertion holes 206 from the outside of the frame and fastened to the screw holes 64 of the reinforcing member 6. In this way, the reinforcing member 6 is fixed between the left and right vertical frame members 23, 24 while attached to the frame-inside projecting surface 203b of the indoor-side projecting portion 203 of the lower frame member 21.

[0030] Furthermore, a synthetic resin cover material 8 having a substantially L-shaped cross section is placed over the upright surface portion 62 and top surface portion 63 of the reinforcing material 6. The cover material 8 of the illustrated embodiment is formed so that the upper edge of a hanging piece portion 81 that covers the upright surface portion 62 of the reinforcing material 6 protrudes slightly further inward than the horizontal piece portion 82 that covers the top surface portion 63 of the reinforcing material 6. The lower edge of the hanging piece portion 81 is positioned so that it is sandwiched between the protruding portion of the indoor-side visible surface 203a of the indoor-side projection portion 203 of the lower frame member 21 and the upright surface portion 62 of the reinforcing material 6. Furthermore, a hook-shaped claw edge 83 that protrudes downward is formed on the outdoor-side side edge of the horizontal piece portion 82, and this claw edge 83 engages with the outdoor-side side edge of the top surface portion 63 of the reinforcing material 6.

[0031] The base 42 of the opening / closing device 4 is connected to the upright surface 62 of the reinforcing member 6 attached to the bottom frame member 21 from the indoor side of the cover member 8, sandwiching the cover member 8 therebetween, with screws 43 or the like. This type of door frame structure allows the reinforcing member 6 to be attached to the bottom frame member 21 with a simple installation procedure that does not require the time and effort of inserting and aligning a separate member into the hollow portion of the bottom frame member 21. The reinforcing member 6 is sandwiched between the left and right vertical frame members 23, 24 that intersect with the bottom frame member 21, and both ends of the reinforcing member 6 are fastened to the left and right vertical frame members 23, 24 with screws. Connecting the base 42 of the opening / closing device 4 to the reinforcing member 6 ensures sufficient installation strength for the opening / closing device 4. Furthermore, this door frame structure ensures that no screws or other mounting members or irregularities are visible on the outer surfaces of the bottom frame member 21, the reinforcing member 6, or the cover member 8, resulting in a pleasing appearance.

[0032] The link mechanism 5, which opens and closes the shoji screen 3 in conjunction with the operation of the opening / closing device 4, is connected to the base 42 through appropriately shaped openings (not shown) formed in the upright surface 62 of the reinforcing member 6 and the hanging piece 81 of the cover member 8. The outdoor end of the link mechanism 5 is connected to the lower frame member 311 that constitutes the lower edge of the frame body 31 of the shoji screen 3. In the illustrated embodiment, a metal frame reinforcement member 33 having a substantially L-shaped cross section is inserted into the hollow portion of the lower frame member 311, and the frame reinforcement member 33 is fastened to the lower frame member 311 with screws so as to align with the bottom surface of the hollow portion and the inner surface of the indoor side. The end of the link mechanism 5 is then connected to the frame reinforcement member 33 from the indoor side with screws or the like. However, the invention disclosed in this application is not limited to the illustrated embodiment in terms of the cross-sectional shape of the frame reinforcement member 33, the manner of attachment to the frame body 31, the manner of connection to the link mechanism 5, etc.

[0033] Furthermore, the technical scope of the invention disclosed herein should not be construed as being limited by the exemplified embodiments, but should be construed conceptually based on the claims. The names of elements used in the claims and the specification are for convenience in making the invention easier to understand specifically, and the names do not unnecessarily limit the concepts or properties of the elements. When implementing the invention disclosed herein, the detailed shape, dimensions, structure, materials, quantity, combination with other elements, relative positional relationship, etc. of elements not specifically specified in the claims may be modified as appropriate within the scope of obtaining effects substantially equivalent to or greater than those of the exemplified embodiments.

[0034] For example, although the invention disclosed in this application was conceived to partially reinforce a synthetic resin frame formed by frame members made of extruded shapes with the same cross-sectional shape on all four sides, it can also be applied to a frame in which the cross-sectional shape of some frame members differs from that of the other frame members, or to a frame formed by assembling frame members that are not extruded shapes.Furthermore, it can also be applied to partially reinforce a frame in which some or all of the frame members are made of metal material, wood material, etc.

[0035] Furthermore, the corners of the frame where two frame members are connected at right angles are not limited to the "stop" form shown in the example, but may also be joined in a "win-lose" form where the end face of one frame member abuts the side face of the other frame member. In this case, the frame member on which the opening and closing device is installed becomes the lose side (the side where the end face abuts the side face of the intersecting frame member).

[0036] Furthermore, the invention disclosed in this application is not limited to fittings that are rectangular when viewed from the front, but can also be applied to fittings in which the upper edge of the frame and shoji screen are semicircular or arc-shaped. Also, the invention can be applied not only to fittings for single windows, but also to fittings for horizontally connected windows and fittings for vertically stepped windows.

[0037] The reinforcing material can also be replaced with a material other than an extruded profile. When using a material other than an extruded profile, a screw receiving portion can be provided by joining or inserting an end plate with screw holes into the end face of the reinforcing material. Furthermore, the reinforcing material can be not only made of metal, but also of high-strength resin material or a composite material in which a metal material and a resin material are integrally molded in advance.

[0038] The type of opening and closing device is not limited to the illustrated operator handle, and any appropriate opening and closing device can be applied depending on the opening and closing method of the shoji screen. The connection form between the opening and closing device and the frame material on which the opening and closing device is installed can also be changed appropriately depending on the opening and closing method of the shoji screen, the type of opening and closing device, the installation location of the opening and closing device, etc. [Industrial Applicability]

[0039] The invention disclosed in this application can be widely used in fitting frames in which the frame body is partially reinforced to install other devices. [Explanation of symbols]
