Description

[Technical Field]

[0001] The present invention relates to a reinforcement structure for a profile having a profile forming a hollow portion, a reinforcing member disposed in the hollow portion, and an accessory fixed to the profile and the reinforcing member. [Background technology]

[0002] For example, in fittings such as sliding windows, an accessory called a friction stay is installed between the frame and the shoji screen. The frame and the shoji screen are joined on all four sides by shaped members. Reinforcements are installed in the hollow parts of the shaped members, and the accessory is sometimes fixed to the shaped members and reinforcements.

[0003] In Patent Document 1, a first reinforcing wall and a second reinforcing wall of a square U-shaped reinforcing member face the inner and outer peripheral projection walls of the extrusion. The inner peripheral projection wall of the extrusion and the first reinforcing wall of the reinforcing member are fixed with a first screw, and the friction stay is fixed to the outer peripheral projection wall and the second reinforcing wall with a second screw. The first reinforcing wall and the second reinforcing wall of the reinforcing member are formed with first screw holes and second screw holes corresponding to the first screw and the second screw.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-076261 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above structure, due to the influence of factors such as shape errors in the reinforcing material, when the inner projection wall and the first reinforcing wall are fixed with the first screw, the second screw hole in the second reinforcing wall may be misaligned with the screw insertion hole in the outer projection wall, making it difficult to screw in the second screw, and this may make it difficult to fix the friction stay.

[0006] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a reinforcement structure for a profile that allows accessory parts to be easily fixed to the profile and reinforcing material. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the object, the reinforcement structure of the present invention for a profile includes a profile forming a hollow portion, a reinforcing member disposed in the hollow portion, an accessory fixed to the profile and the reinforcing member, a positioning tool for positioning the reinforcing member relative to the profile, and a fastener for fastening the accessory to the profile and the reinforcing member, wherein the hollow portion is formed by a wall portion including a first hollow wall and a second hollow wall facing each other, and the reinforcing member is disposed in the hollow portion and faces the first hollow wall. The present invention is characterized in that the first reinforcing wall faces the first hollow wall and the second reinforcing wall faces the second hollow wall, wherein the first reinforcing wall is provided with an attachment portion for attaching the positioning tool, the first hollow wall is provided with a first hole through which the positioning tool is inserted, the second reinforcing wall is provided with a fixing portion for fixing the fixing tool, and the second hollow wall is provided with a second hole at a position corresponding to the fixing portion through which a portion of the fixing tool is inserted, and the portion of the positioning tool is arranged with a gap within a range surrounded by the inner surface of the first hole. [Effects of the Invention]

[0008] In the reinforcement structure for extruded profiles of the present invention, if a manufacturing error occurs in the reinforcement material, the first hole is larger than a part of the positioning device, so the reinforcement material can be slightly displaced and the position of the second hole and the fixing part can be adjusted, making it possible to easily fix accessories to the extruded profile and reinforcement material.

DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a reinforcement structure for a profile according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments.

[0011] For convenience, the terms "prospect direction" and "prospect wall" may be used below. The prospect direction (the direction indicated by arrow Z in the diagram) is the indoor / outdoor direction along the depth of the fixture. Surfaces and walls along the prospect direction may be called prospect surfaces and prospect walls. The prospect direction is the direction perpendicular to the prospect direction (the direction indicated by arrow Y in the diagram) for items that extend horizontally, such as upper frames, lower frames, upper stiles, and lower stiles, and the direction perpendicular to the prospect direction (the direction indicated by arrow X in the diagram) for items that extend vertically, such as vertical frames and vertical stiles. Surfaces and walls along the prospect direction may be called prospect surfaces and prospect walls.

[0012] FIG. 1 is a view of a fitting 11 including a reinforcement structure 10 for a shaped member according to an embodiment of the present invention, as seen from the inside of a room. FIG. 2 is a vertical cross-sectional view of the fitting 11. FIG. 3 is a horizontal cross-sectional view of the fitting 11. The fitting 11 is a vertical sliding window, and has a frame 12 installed in an opening in a building, and a shoji screen 14 installed on the inner periphery of the frame 12. The shoji screen 14 can be opened and closed toward the outside of the room relative to the frame 12. In this embodiment, the left side in FIG. 1 is used as the reference side, and the right side opens and closes. The reinforcement structure 10 for a shaped member can also be applied to fittings other than sliding windows.

[0013] The shoji screen 14 is constructed by placing a panel 24 inside a frame body 22, which is formed by assembling a bottom frame 16, an top frame 18, and left and right vertical frames 20 around the entire perimeter. In this embodiment, the panel 24 is double-glazed. The panel 24 has three panes of glass and is slightly thicker than a panel with two panes. The frame body 12 is constructed by assembling a bottom frame 26, an top frame 28, and left and right vertical frames 30 around the entire perimeter. Each frame and frame material is an extruded material, each configured to have a substantially uniform cross-sectional shape along its entire length. In this embodiment, the frame materials are made of resin, and the frame material is made of a metal such as an aluminum alloy or a resin. An opening / closing handle 32 is provided at approximately the midpoint of the right side of the shoji screen 14 in Figure 1.

[0014] As shown in Figure 2, the bottom frame 16 and the top frame 18 are symmetrical from top to bottom, and the bottom frame 26 and the top frame 28 are symmetrical from top to bottom. In addition, friction stays 34, which are accessories, are provided between the bottom frame 16 and the bottom frame 26, and between the top frame 18 and the top frame 28. In this way, the building material 11 is essentially symmetrical from top to bottom, and the reinforcement structures 10 for the shaped member are provided on the top and bottom. In the following explanation, the reinforcement structure 10 for the shaped member relating to the bottom frame 16 will be mainly described, and as a modified example, the reinforcement structure 10A for the shaped member relating to the bottom frame 26 (see Figure 9) will also be described. The vertical frame 20 and vertical frame 30 are the same as the bottom frame 16 and bottom frame 26 (see Figure 3).

[0015] The shaped member reinforcement structure 10 includes a bottom frame 16, a friction stay 34, and a reinforcement member 36. The friction stay 34 is a link mechanism that allows the sliding movement of the shoji screen 14 relative to the frame body 12. The bottom frame 16 is roughly crank-shaped and includes an exterior hollow section 38, an interior hollow section 40, a central hollow section 42, and small hollow sections 44 and 46. The exterior hollow section 38 protrudes downward on the exterior side. The interior hollow section 40 protrudes upward on the interior side. The hollow section 44 is adjacent to the upper side of the exterior hollow section 38. The hollow section 46 is adjacent to the exterior side of the central hollow section 42. The central hollow section 42 is connected to the lower part of the interior hollow section 40 on the interior side and is connected to the hollow section 44 via the hollow section 46 on the exterior side. The central hollow portion 42 is configured by walls including an upper wall 42a (first hollow wall) and a lower wall 42b (second hollow wall). The upper wall 42a and the lower wall 42b have approximately the same projection width and are projection walls that face each other vertically.

[0016] The upper surface of the hollow portion 44 has a claw 48 that engages with the ridge 50. The ridge 50 and the indoor-side hollow portion 40 hold the edge of the panel 24. The ridge 50, the indoor-side hollow portion 40, the top wall 42a of the central hollow portion 42, and the top wall of the hollow portion 46 form a panel holding space 52 that holds the panel 24. The top wall 42a occupies most of the bottom wall of the panel holding space 52. The top wall 42a has an appropriately long projected width in accordance with the thickness of the panel 24, and the central hollow portion 42 has a horizontally elongated shape on the page of FIG. 2. In this embodiment, the aspect ratio of the central hollow portion 42 is approximately 1:2.

[0017] The lower frame 26 comprises a main hollow section 54, an exterior hollow section 56, a hollow section 58, and an interior facing section 60. The main hollow section 54 is the largest part of the lower frame 26 and is slightly oblong in the plane of FIG. 2. A pair of small protrusions 54a facing each other in the forward direction are formed in the main hollow section 54, and a reinforcing plate 62 is provided between the small protrusions 54a and the upper wall 54b. The reinforcing plate 62 is made of steel or the like. The hollow section 58 is a slightly smaller section adjacent to the exterior side of the main hollow section 54. The exterior hollow section 56 protrudes from the hollow section 58 to the exterior and has a gently sloping upper surface. The interior facing section 60 is composed of three hollow sections and protrudes upward from the interior side of the main hollow section 54.

[0018] A seal 64 is provided between the upper protruding piece 58a of the hollow portion 58 and the lower end of the exterior hollow portion 38. A seal 66 is provided between the upper end of the interior facing portion 60 and the lower end of the interior hollow portion 40. An accessory space 68 is formed between the upper wall 54b of the main hollow portion 54 and the lower wall 42b of the central hollow portion 42, in which the friction stays 34 are arranged with almost no gap between them. When the shoji screen 14 is closed, the accessory space 68 is sealed by the seals 64, 66. The friction stay 34 has its upper member 34a fixed to the lower wall 42b and reinforcing member 36 by screws (fixing devices) 70, and its lower member 34b fixed to the upper wall 42a and reinforcing plate 62 by screws 72.

[0019] Fig. 4 is a vertical cross-sectional view of the central hollow portion 42 and the reinforcing member 36. Fig. 5 is a plan view of the screw insertion holes 76 and the screws 78. Note that Figs. 4, 6, 7, 8, and 9 are cross-sectional views of the YZ plane perpendicular to the extension direction (X direction) of the lower frame 16, and in each figure, the in-plane direction of the upper wall 42a and the lower wall 42b corresponds to the front direction (Z direction), and the direction perpendicular to the plane corresponds to the front direction (Y direction).

[0020] The reinforcing member 36 is disposed within the central hollow portion 42 over substantially the entire length of the bottom frame 16 (see FIG. 1 ) and has a rectangular U-shape (including a rectangular J-shape) consisting of a first reinforcing wall 36a, a second reinforcing wall 36b, and a third reinforcing wall 36c. The first reinforcing wall 36a forms the upper visible wall, the second reinforcing wall 36b forms the lower visible wall, and the third reinforcing wall 36c is a visible wall connecting the exterior ends of the first reinforcing wall 36a and the second reinforcing wall 36b. The first reinforcing wall 36a faces the upper wall 42a, and the second reinforcing wall 36b faces the lower wall 42b. In this application, the visible width of the first reinforcing wall 36a is approximately half that of the second reinforcing wall 36b. The reinforcing member 36 is formed by bending the first reinforcing wall 36a and the third reinforcing wall 36c, and the third reinforcing wall 36c and the second reinforcing wall 36b at right angles. The reinforcing member 36 may be an extruded member or the like. The reinforcing member 36 is made of steel or the like, and reinforces the resin bottom frame 16. The reinforcing member 36 has two bent portions, making it very strong.

[0021] A female screw hole (mounting portion) 74 is formed in the first reinforcing wall 36a. A screw insertion hole (first hole) 76 is formed in the upper wall 42a at a position corresponding to the screw hole 74, and a screw (positioning tool) 78 is attached by passing through the screw insertion hole 76 and threading into the screw hole 74. By design, the screw hole 74 and the screw insertion hole 76 are concentric.

[0022] The screw insertion hole 76 has a diameter slightly larger than the head (part) 78a of the screw 78. In other words, the head 78a is disposed with a gap G within an area 80 surrounded by the inner circumferential surface of the screw insertion hole 76. The gap G basically exists in all directions, but FIG. 5 illustrates the gap G in the X and Z directions. In FIG. 4, the area 80 is indicated by a dotted background. In this embodiment, the screw 78 is an M4 size countersunk head screw, with the diameter of the head 78a being approximately 6 mm and the diameter of the screw insertion hole 76 being approximately 8 mm. Furthermore, if the diameter of the head 78a is 7 mm, the diameter of the screw insertion hole 76 is approximately 9 mm. In other words, in this embodiment, when the head 78a and the screw insertion hole 76 are concentrically aligned, the gap G is approximately 1 mm for each.

[0023] A plurality of screws 78 and screw insertion holes 76 may be provided along the X direction. Depending on the specifications, the heads 78a may protrude slightly from the upper surface of the top wall 42a. In this embodiment, the heads 78a and screw insertion holes 76 are circular, but they may have other shapes. In this embodiment, the first assembly means (e.g., a robot) that performs the screwing work of the screws 78 works from the inner peripheral visible surface of the lower frame 16, and therefore the screw holes 74 are provided in the first reinforcing wall 36a and the screw insertion holes 76 are provided in the top wall 42a.

[0024] The second reinforcing wall 36b of the reinforcing member 36 is provided with a female screw hole (fixing portion) 82 into which the screw 70 is threaded. The screw hole 82 is a fixing portion that fixes the screw 70 as a fixing device. The screw hole 82 is provided in the second reinforcing wall 36b slightly toward the interior of the room and in a position that does not face the first reinforcing wall 36a.

[0025] The lower wall 42b is provided with screw insertion holes (second holes) 84 at positions corresponding to the screw holes 82. The screw insertion holes 84 have a smaller diameter than the heads 70a of the screws 70 (see FIG. 6). The male threads of the screws 70 are inserted into the screw insertion holes 84, and the heads 70a press against the periphery of the screws 70 via the upper member 34a, thereby fixing the friction stay 34 to the second reinforcing wall 36b and the lower wall 42b. The number of screws 70 and screw insertion holes 84 depends on the specifications of the friction stay 34. In this embodiment, the second assembly means (e.g., a worker) who performs the screwing operation of the screws 70 works from the visible surface on the outer periphery of the lower frame 16, and therefore the screw holes 82 are provided in the second reinforcing wall 36b and the screw insertion holes 84 are provided in the lower wall 42b.

[0026] As shown in Fig. 4, the front-facing length W1 of the reinforcing member 36 is smaller than the front-facing length W2 of the central hollow portion 42, with the difference being ΔW (ΔW1 + ΔW2 in Fig. 4). The front-facing length H1 of the reinforcing member 36 is smaller than the front-facing length H2 of the central hollow portion 42, with the difference being ΔH. In this way, the reinforcing member 36 is slightly smaller than the central hollow portion 42, making it easier to insert the reinforcing member 36 into the central hollow portion 42. The total width of the gap G between the head 78a and the screw insertion hole 76 (G x 2 in Fig. 5) is set to be equal to or less than the total width (ΔW1 + ΔW2) of the front-facing differences ΔW1 and ΔW2 between the reinforcing member 36 and the central hollow portion 42.

[0027] Figure 6 is an exploded view of the reinforcement structure 10 for extrusions. In assembling this part of the fitting 11, the first step is to insert the reinforcement member 36 into the central hollow portion 42. Although the reinforcement member 36 is fairly long, its projected length and visible length are slightly smaller than those of the central hollow portion 42, allowing for smooth insertion.

[0028] In the second step, the male thread of the screw 78 is inserted into the screw insertion hole 76 and screwed into the screw hole 74. The head 76a of the screw 78 is then positioned within an area 80 defined by the inner circumferential surface of the screw insertion hole 76, and the reinforcing member 36 is allowed to move slightly, though its movement in the longitudinal direction (X direction) and the longitudinal direction (Z direction) is limited. Thus, the screw 78 does not completely fix the reinforcing member 36 to the central hollow portion 42, but acts as a positioning tool to prevent large displacement. This positioning function prevents the reinforcing member 36 from falling out or shifting significantly, even when the lower frame 16 is moved between assembly steps. The screw hole 74 has a smaller diameter than the screw insertion hole 76 and is fully exposed in a plan view, facilitating the screwing operation using a first assembly means such as a robot.

[0029] Next, in the third step, the screws 70 are inserted into the screw insertion holes 84 from the lower member 34b of the friction stay 34 and screwed into the screw holes 82. The heads 70a of the screws 70 press against the periphery of the screw insertion holes 84 via the upper member 34a, thereby fixing the friction stay 34 to the lower frame 16 and the reinforcing member 36. Depending on the assembly conditions, the lower member 34b of the friction stay 34 may be fixed to the lower frame 26 in advance.

[0030] Figure 7 is a vertical cross-sectional view of the central hollow portion 42 and the reinforcement member 36 when there is a manufacturing error in the reinforcement member 36. In the reinforcement member 36, the screw hole 74 is on the upper side, while the screw hole 82 is on the lower side, and they are somewhat spaced apart along the angular U-shape. Furthermore, because the reinforcement member 36 includes two bent portions, there is a concern that manufacturing errors may occur in the relative positions and angles. Figure 7 shows an example in which there is an angle error in the bent portion of the reinforcement member 36.

[0031] Even if a manufacturing error occurs in the reinforcing member 36, in the reinforcing structure 10 for a profile member according to this embodiment, the screw insertion hole 76 has a diameter slightly larger than the head portion 78a, allowing the reinforcing member 36 to be slightly displaced in the projection direction and longitudinal direction, making it possible to adjust the screw hole 82 and the screw insertion hole 84 to be concentric. Furthermore, if the axis of the screw hole 74 is slightly deviated from the projection direction (see FIG. 7), the head portion 78a will only be slightly tilted within the range 80, which will not affect the adjustment of the positions of the screw hole 82 and the screw insertion hole 84. In this way, in the reinforcing structure 10 for a profile member according to this embodiment, the positions of the screw hole 82 and the screw insertion hole 84 can be adjusted, allowing the second assembly means, such as a worker, to easily fix the friction stay 34 to the bottom frame 16 and the reinforcing member 36.

[0032] Because the projection length W1 of the reinforcing member 36 is smaller than the projection length W2 of the central hollow portion 42, it is easy to adjust the position in the projection direction. The reinforcing member 36 has a projection movement margin equal to the difference ΔW between the lengths W1 and W2. Therefore, it is not effective to set the gap between the head 78a and the screw insertion hole 76 (G×2 in FIG. 5) larger than this. In other words, it is reasonable to set the width of the gap between the head 78a and the screw insertion hole 76 to ΔW or less in the projection direction. Because the head 78a and the screw insertion hole 76 are circular, it is preferable to set the gap to a similar value in the longitudinal direction.

[0033] Although the length H1 of the reinforcing member 36 in the view direction is smaller than the length H2 of the central hollow portion 42 in the view direction, the first reinforcing wall 36a is not fixed to the upper wall 42a, so the reinforcing member 36 does not float, and the second reinforcing wall 36b is seated on the lower wall 42b and securely fixed by the screws 70. Because the length H1 is smaller than H2, even if the two bent portions of the reinforcing member 36 are not exactly at right angles (see FIG. 7), the first reinforcing wall 36a does not come into contact with the upper wall 42a or only lightly comes into contact with it, so excessive force is not applied to the reinforcing member 36, and there is almost no effect on the position adjustment of the screw holes 82 and the screw insertion holes 84.

[0034] 8 is a longitudinal cross-sectional view of the central hollow portion 42 and a reinforcing member 36A according to a modified example. While the reinforcing member 36 described above has a rectangular U-shape, the reinforcing member 36A has a closed rectangular shape and includes a third reinforcing wall 36c and a fourth reinforcing wall 36d that connect the ends of the first reinforcing wall 36a and the second reinforcing wall 36b. The first reinforcing wall 36a in this example is longer than the first reinforcing wall 36a in the reinforcing member 36 described above, and the ends of the first reinforcing wall 36a and the fourth reinforcing wall 36d abut against each other. While the reinforcing member 36 described above can be manufactured inexpensively, the reinforcing member 36A has higher strength.

[0035] 9 is a vertical cross-sectional view of a reinforcement structure 10A for a shaped member in which a reinforcement member 90 is applied to the main hollow portion 54 of the lower frame 26. The reinforcement member 90 is applied to the main hollow portion 54 in place of the reinforcing plate 62 described above and has a rectangular U-shape. However, it is larger than the reinforcement member 36 described above and is upside down to correspond to the main hollow portion 54. The reinforcement member 90, first reinforcing wall 90a, second reinforcing wall 90b, third reinforcing wall 90c, screw 92, head portion 92a, screw hole 94, screw insertion hole 96, screw 72, screw hole 98, and screw insertion hole 100 in the reinforcement structure 10A for a shaped member correspond to the reinforcement member 36, first reinforcing wall 36a, second reinforcing wall 36b, third reinforcing wall 36c, screw 78, head portion 78a, screw hole 74, screw insertion hole 76, screw hole 82, screw 70, screw hole 82, and screw insertion hole 84 in the above embodiment (see FIGS. 2 and 4). The upper wall 42a and the lower wall 42b in FIG. 9 correspond to the lower wall 54c and the upper wall 54b.

[0036] In the reinforcement structure 10A for the shaped member, the head 92a has a smaller diameter than the screw insertion hole 96, so the position of the reinforcement member 90 can be adjusted and the friction stay 34 can be easily fixed with the screw 72. In this way, the present invention is applicable to shaped members that form part of the frame or stile in the fitting 11, and is also applicable to the vertical frame 20 and the vertical frame 30.

[0037] In the above-mentioned reinforcement structures 10, 10A for extrusions, the positioning and fixing of the accessory parts to the recessed wall of the hollow section of the extrusion is performed using screws in the recessed direction, but the positioning and fixing of the accessory parts to the recessed wall may also be performed using screws in the recessed direction. The friction stay 34 to be fixed is classified as an opening / closing part, but other opening / closing parts as accessory parts include safety stoppers. In addition, locking parts as accessory parts include cremone locks and lock receiving parts, and further reinforcing parts as accessory parts include parts to prevent glass from falling out. Hinges can also be considered accessory parts. In addition to screws, fixing and positioning devices include rivets.

[0038] The present invention is not limited to the above-described embodiment, and can of course be freely modified within the scope of the gist of the present invention.

[0039] The reinforcement structure for a shaped member in this embodiment is a reinforcement structure for a shaped member having a shaped member that forms a hollow portion, a reinforcing material that is placed in the hollow portion, an accessory part that is fixed to the shaped member and the reinforcing material, a positioning device that positions the reinforcing material relative to the shaped member, and a fixing device that fixes the accessory part to the shaped member and the reinforcing material, wherein the hollow portion is formed by wall portions including opposing first and second hollow walls, the reinforcing material includes a first reinforcing wall that faces the first hollow wall and a second reinforcing wall that faces the second hollow wall, the first reinforcing wall is provided with a fixing portion for attaching the positioning device, the first hollow wall is provided with a first hole through which the positioning device is inserted, the second reinforcing wall is provided with a fixing portion for fixing the fixing device, and the second hollow wall is provided with a second hole through which a portion of the fixing device is inserted at a position corresponding to the fixing portion, and a portion of the positioning device is arranged with a gap within a range surrounded by the inner surface of the first hole.

[0040] In this type of reinforcement structure for extrusions, if there is a manufacturing error in the reinforcement, the first hole is larger than part of the positioning device, so the reinforcement can be slightly displaced and the position of the second hole and the fixing part can be adjusted, making it easy to fix accessories to the extrusion and reinforcement.

[0041] In a cross section perpendicular to the extending direction of the profile, the length of the reinforcing material in a direction perpendicular to the surface of the first hollow wall and the second hollow wall may be smaller than that of the hollow portion. Also, in a cross section perpendicular to the extending direction of the profile, the length of the reinforcing material in an in-plane direction of the first hollow wall and the second hollow wall may be smaller than that of the hollow portion. This makes it easier to insert the reinforcing material into the hollow portion.

[0042] It is reasonable that the width of the gap between the part of the positioning tool and the first hole is equal to or less than the width of the gap in the in-plane direction between the reinforcing material and the hollow portion.

[0043] The positioning tool may be a screw, the head of which is within a range surrounded by the inner circumferential surface of the first hole.

[0044] When the first hole and the portion of the positioning tool located within the area surrounded by the inner circumferential surface of the first hole are each circular, there is no directivity in a particular direction.

[0045] The reinforcing material may be an angular U-shape having a third reinforcing wall connecting one end of each of the first reinforcing wall and the second reinforcing wall, or a rectangle having a third reinforcing wall and a fourth reinforcing wall connecting both ends of the first reinforcing wall and the second reinforcing wall.

[0046] The profile may form part of a frame or a stile in a building fixture.

[0047] The fixing portion may be a female screw hole. [Explanation of symbols]
