Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, there are cases where a large building structure is made of wood, and a large shutter device such as a weight shutter is installed on the wooden structure. In such a case, a relatively heavy guide rail is fixed to the wooden structure by a fixing tool such as a screw or a bolt. However, in the conventional fixing mode using a fixing tool, the fixing tool such as a screw or a bolt is screwed substantially perpendicular to the surface of the structure, and there is a risk of coming off against a strong external force, and there is room for improvement. Also, in the event of a fire, the heat from the fire is transmitted to the fixing tool, and the fixing portion of the fixing tool in the wooden structure may be thermally deteriorated, resulting in loosening or falling off of the fixing tool.

[0005] An object of the present invention is to provide a fixture that firmly fixes a component constituting an opening / closing device to a wooden structure and stably and reliably installs the opening / closing device.

Means for Solving the Problems

[0006] In view of such problems, one aspect of the present invention has the following configuration. A fixture for fixing a component of an opening / closing device that opens and closes an opening to an attachment surface of a wooden housing, the fixture comprising: a fastening member having a shaft portion that can be screwed into the wooden housing and a head portion provided at the rear end of the shaft portion; and a receiving seat for receiving the head portion of the fastening member, wherein the receiving seat has an inclined portion disposed in an inclined manner with respect to the upper surface of the component and a rising portion connected to one edge of the inclined portion and extending substantially perpendicular to the upper surface of the component, a first insertion hole penetrating substantially perpendicular to the upper surface of the inclined portion is formed in the inclined portion, the shaft portion of the fastening member is inserted through and guided by the first insertion hole, and the component is fixed to the wooden housing by screwing in an inclined state with respect to the attachment surface of the wooden housing.

Advantages of the Invention

[0007] Since the present invention is configured as described above, a component constituting an opening / closing device can be firmly fixed to a wooden housing, and the opening / closing device can be installed stably and reliably. Further, even if flames or heat due to a fire act on the outer surface of the wooden housing where the fastening member is fastened, loosening or falling off of the fastening member can be suppressed.

Embodiments for Carrying Out the Invention

[0009] Next, embodiments according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a front schematic view showing an opening / closing device to which the fixing structure of the opening / closing device according to the present invention is applied, FIG. 2 is a longitudinal sectional schematic view taken along line (II)-(II) of FIG. 1, and FIG. 3 is an example (fixing structure of a guide rail) of the fixing structure of the opening / closing device according to the present invention, which is a cross-sectional schematic view taken along line (III)-(III) of FIG. 1.

[0010] In this specification, the "width direction of the opening / closing body" means a direction substantially orthogonal to the opening / closing direction of the opening / closing body and not the thickness direction of the opening / closing body. Further, the "inner side in the width direction of the opening / closing body" means the direction side facing inward of the opening / closing body along the width direction of the opening / closing body. For example, with reference to the guide rail 40A on the right side in FIG. 1, the inner side in the width direction of the opening / closing body is the left direction side. Further, the "outer side in the width direction of the opening / closing body" means the direction side facing outward of the opening / closing body along the width direction of the opening / closing body. For example, with reference to the guide rail 40A on the right side in FIG. 1, the outer side in the width direction of the opening / closing body is the right direction side.

[0011] (First Embodiment) The opening / closing device 1 includes an opening / closing body 10 that closes in a manner of partitioning a space, a storage unit 20 that feeds out the opening / closing body 10 in the closing direction or stores it in the opening direction, and a guide rail 40A that guides the opening / closing body 10 in the closing direction and the opening direction.

[0012] The wooden building X is a large building mainly made of wood. This wooden building X includes a wooden base x1 and a fire-resistant member x2 that covers the wooden base x1 (see FIGS. 2 and 3).

[0013] The wooden base x1 is a wooden building material that constitutes the basic framework of the wooden structure X. For example, it is a square-columnar piece of wood that constitutes a pillar or a beam, or a flat structural plywood that constitutes a wall surface, etc. In the illustrated example, the wooden base x1 is erected from the floor surface below the opening / closing device 1 to the ceiling part 2 above the opening / closing device 1.

[0014] The fire-resistant member x2 is a plate-shaped building material having fire resistance and heat insulation properties (for example, a gypsum board, a calcium silicate board, etc.), and is provided by being stacked singly (single-layer structure) or plurally (multi-layer structure: two sheets according to the illustrated example) on the surface of the wooden base x1.

[0015] The opening / closing body 10 is formed by connecting a plurality of slats formed by bending a horizontally long substantially rectangular metal plate so as to rotate up and down, and may be referred to as a slat shutter curtain. As another example of this opening / closing body 10, a mode made of a flexible sheet, a mode made of a plurality of panels, a mode in which a plurality of pipes are arranged at intervals in the vertical direction, a mode in which slats, flexible sheets, panels, pipes, etc. are appropriately combined, etc. are possible.

[0016] The storage part 20 includes a winding shaft 21 for winding and unwinding the opening / closing body 10, shaft support brackets 30, 30 that support the winding shaft 21 at both ends thereof, a winding shaft case 23 that covers the periphery of the winding shaft 21 and the opening / closing body 10 wound around the winding shaft 21, an opening / closing machine 24 that is a drive source for driving the winding shaft 21 to rotate, a support base frame 25 that supports the shaft support brackets 30, 30, etc. (see FIGS. 1 and 2).

[0017] The winding shaft 21 is configured in a long cylindrical shape extending in the width direction of the opening / closing body and is rotatably supported. This winding shaft 21 may be configured in a mode in which a winding body is rotatably supported via a bearing on the outer periphery of a non-rotatable fixed shaft, or a mode in which a shaft portion integrated with the winding body is rotatably supported via a bearing with respect to the shaft support bracket 30, etc.

[0018] The take-up shaft case 23 is formed in a long shape with a longitudinal cross-section such as a substantially U-shape or an arc shape continuous in the opening / closing width direction. This take-up shaft case 23 is fixed to the support base frame 25 so as to cover the periphery of the take-up shaft 21 and the opening / closing body 10 wound around the take-up shaft 21 from the front side (left side according to FIG. 2).

[0019] The opening / closing machine 24 is composed of an electric motor, gears, etc. This opening / closing machine 24 is supported by one of the shaft support brackets 30 (right side according to FIG. 1), and its rotational force is transmitted to the take-up shaft 21 by a chain, sprocket, etc. (not shown).

[0020] The support base frame 25 is integrally configured to have a long connecting portion 25a that connects the left and right shaft support brackets 30, 30 at their lower end sides by connecting a plurality of long rigid members (for example, various steel materials such as angle steel and channel steel), and a support portion 25b that supports a substantially central portion in the lateral width direction of the connecting portion 25a and is fixed to the rear wooden structure X. In FIG. 1, an example in which one support portion 25b is arranged in the lateral width direction of the connecting portion 25a is shown, but the number of installed support portions 25b arranged may be plural.

[0021] The left and right shaft support brackets 30, 30 and the support portion 25b are immovably fixed to the wooden structure X by fixing tools M1 such as screws, bolts, and anchor members.

[0022] The guide rail 40A is a long member continuous in the vertical direction at both end sides in the width direction of the opening / closing body 10. This guide rail 40A is fixed to the finding surface Xa (mounting surface) of the wooden structure X so as to guide the width direction end portion of the opening / closing body 10 in the opening / closing direction.

[0023] (Structure of the guide rail) Hereinafter, the specific structure of the guide rail 40A will be described. FIG. 4 is an explanatory diagram showing an example of the fixed structure of the opening / closing device according to the present invention disassembled into components. Specifically, the installation structure for installing the guide rail 40A on the wooden structure X is shown.

[0024] As shown in FIGS. 3 and 4, the guide rail 40A as a component of the opening / closing device 1 includes a rail body 41 having a hollow cross-sectional L shape that protrudes forward from the finding surface Xa (mounting surface) of the wooden housing X and bends the tip side inward in the width direction of the opening / closing body (left side according to FIG. 3), a base member 42 for fixing the rail body 41 to the finding surface Xa of the wooden housing X, and a reinforcing member 43 disposed in the rail body 41 to reinforce the rail body 41, which are integrally provided. These rail body 41, base member 42, and reinforcing member 43 are each formed of a hard metal material (for example, steel, stainless steel, aluminum alloy, etc.).

[0025] As shown in FIG. 4, the base member 42 has a substantially concave cross section having a plate-shaped portion 42a as a mounting portion in contact with the finding surface Xa (mounting surface) of the wooden housing X, and protruding pieces 42b, 42b protruding forward from both left and right end portions of the plate-shaped portion 42a, which is continuously long in the vertical direction. This base member 42 is fixed to the finding surface Xa of the wooden housing X by a fastener M1 inserted through the plate-shaped portion 42a.

[0026] The rail body 41 integrally has a guide portion 41a that surrounds the widthwise end portion of the opening / closing body 10 in a concave cross section and guides it in the vertical direction, and a support portion 41b that protrudes forward from the finding surface Xa of the wooden housing X and supports the guide portion 41a. This rail body 41 overlaps the rear end portion of the support portion 41b with both protruding pieces 42b, 42b of the base member 42 fixed in advance. The overlapping portion is integrally joined by a fastener (not shown) inserted therethrough (for example, a screw, a bolt, a rivet, etc.). And a closed space S is formed in the support portion 41b (see FIG. 3).

[0027] Also, the surface on the inner side in the width direction of the opening / closing body of the guide rail 40A (left side according to FIG. 3) is covered with a fire-resistant member x3 made of the same building material as the fire-resistant member x2. Note that a fire-resistant member may also be arranged on the surface on the outer side in the width direction of the opening / closing body of the guide rail 40A (right side according to FIG. 3).

[0028] Further, the lower end of the guide rail 40A is fixed to a lower stationary part (e.g., the floor surface, the lower frame, the sliding door sill, etc.) via a bracket or the like (not shown). Also, the upper end is fixed to an upper stationary part (e.g., the ceiling part 2, the steel materials on the ceiling side, the beam materials, etc.) via a bracket or the like (not shown).

[0029] In addition, as another example of the guide rail 40A, it is possible to adopt a mode in which it is formed into a hollow column shape from a plurality of members other than the illustrated example, a mode in which it is formed into an integral hollow tubular shape, and the like.

[0030] (Installation of the guide rail) Next, a specific structure related to the installation of the guide rail 40A will be described with reference to the drawings. FIG. 5 is a schematic view showing an example of a fixture (receptacle) in the fixing structure of the guide rail 40A, FIG. 5(a) is a side schematic view of the receptacle, and FIG. 5(b) is a rear schematic view of the receptacle as viewed from the back side. FIG. 6 is a perspective schematic view of the receptacle shown in FIG. 5 as viewed from the front side, and FIG. 6(b) is a perspective schematic view showing another example (modified example) of the receptacle. FIG. 7 is a side schematic view for explaining examples of a plurality of receptacles with different inclination angles with respect to the receptacle.

[0031] The guide rail 40A is attached to the wooden structure X using fixtures such as the fastener M1 and the receptacle 50. [Fastener] The fastener M1 is a shaft portion having a screw portion m11 on the tip side and a screwing member (e.g., a screw or a bolt) having a head m12 on the rear end side, and a plurality of them are provided at intervals in the vertical direction. This fastener M1 is driven obliquely into the finding surface Xa of the wooden structure X via the receptacle 50. The screw portion m11 (shaft portion) of the fastener M1 penetrates the receptacle 50 and the base member 42 and is screwed in an inclined state with respect to the finding surface xa (mounting surface) of the wooden structure X.

[0032] [Receptacle] The receiving seat 50 functions as guiding means for guiding the shaft portion m11 of the fastener M1 in an oblique direction with respect to the finding surface Xa (mounting surface) of the wooden structure X, and is configured such that the fastener M1 can be driven (screwed) obliquely into the finding surface Xa of the wooden structure X. This receiving seat 50 has, for example, as shown in FIGS. 4 to 6, a rising portion 51 extending substantially perpendicular to the plate-like portion 42a of the base member 42, a flat plate portion 53 (first abutting portion) extending along the plate-like portion of the base member 42, and an inclined portion 52 connected to one edge of the rising portion 51 and one edge of the flat plate portion 53, and is formed, for example, by bending a flat plate-shaped metal plate.

[0033] Note that the receiving seat 50 can also be composed of the rising portion 51 and the inclined portion 52, omitting the flat plate portion 53 (first abutting portion). In this case, the edge of the rising portion 51 and the edge of the inclined portion 52 will be arranged in contact with the plate-like portion 42a of the base member 42.

[0034] FIGS. 5 and 6(a) show a short receiving seat 50 configured to be able to insert one fastener M1. In the illustrated example, the inclined portion 52 has substantially the same vertical and horizontal dimensions and is formed substantially square in a front view. A screw hole 52a (first insertion hole) for inserting the screw portion m11 of the fastener M1 is formed substantially at the center of the inclined portion 52. The peripheral portion surrounding this screw hole 52a is configured to receive the head m12 of the fastener M1.

[0035] The screw hole 52a is substantially equal to the outer diameter of the screw portion m11 of the fastener M1 and is formed to penetrate substantially perpendicular to the surface of the inclined portion 52. The screw portion m11 of the fastener M1 will be inserted along this screw hole 52a, and as a result, the fastener M1 will be screwed obliquely with respect to the finding surface Xa of the wooden structure X. Therefore, the guide rail 40A can be firmly fixed to the wooden structure X (strongly fixed against external forces).

[0036] Further, as shown in Fig. 6(b), the receiving seat 50 may be configured as a long receiving seat 50' through which a plurality of fasteners M1 can be inserted. This long receiving seat 50' is configured as a long receiving seat whose length in the orthogonal direction orthogonal to the inclination direction of the inclined portion 52 is longer than the length in the inclination direction of the inclined portion 52.

[0037] A plurality of screw holes 52a (first insertion holes) are formed in the inclined portion 52 at a predetermined interval along the orthogonal direction orthogonal to the inclination direction of the inclined portion 52. This long receiving seat 50' is also formed with a rising portion 51, an inclined portion 52, and a flat plate portion 53 (first abutting portion) in the same manner as the above-described short receiving seat 50. The same components are denoted by the same reference numerals and redundant descriptions are omitted.

[0038] Also, as shown in Figs. 7(a) to 7(c), the inclination angles α of the inclined portion 52 with respect to the flat plate portion 53 (first abutting portion) in the receiving seats 50 and 50', specifically, the inclination angles α1, α2, and α3 of the inclined portion 52 with respect to the plane (or finding plane xa) of the flat plate portion 53 can be set to any angle (acute angle) at which the guide rail 40A can be firmly fixed to the wooden housing X (strongly fixed against external forces), and is not particularly limited. For example, by setting the inclination angle α to 10 to 30 degrees, the workability during the installation of the guide rail 40A (for example, when screwing in the fastener M1) can be improved. In the figure, the dashed-dotted line indicates the position of the shaft portion of the fastener M1 passing through the screw hole 52a (first insertion hole) formed in the inclined portion 52.

[0039] Also, as shown in Figs. 7(a) to 7(c), for example, when installing the guide rail 40A, if a plurality of receiving seats 50 with different inclination angles α (α1, α2, α3) are prepared, the receiving seat 50 can be selected according to the on-site situation, so the workability is improved. This receiving seat 50 can also be formed of a non-metallic material such as silicon or plastic having fire resistance and heat insulation properties.

[0040] (Construction method of guide rail) Next, an example of the construction method (construction procedure) of the guide rail 40A will be described.

[0041] <Step 1: Arrangement of the base member> First, the base member 42 of the guide rail 40A is arranged on the finding surface Xa (mounting surface) of the wooden structure X. In this case, the back surface of the plate-shaped portion 42a of the base member 42 is arranged so as to be in contact with the finding surface Xa of the wooden structure X.

[0042] <Step 2: Arrangement of the receiving seat> Next, the receiving seat 50 is arranged at a predetermined position of the base member 42. In this case, the receiving seat 50 can be easily positioned by bringing the outer surface of the rising portion 51 of the receiving seat 50 into contact with the inner surface of the projecting piece portion 42b on the other side of the base member 42. In this state, the inclined portion 52 of the receiving seat 50 is inclined with respect to the plate-shaped portion 42a of the base member 42.

[0043] Note that an adhesive or an adhesive material may be provided on the outer surface of the rising portion 51 and / or the flat plate portion 53 of the receiving seat 50 so that it can be temporarily attached to the base member 42. Also, the receiving seat 50 may be configured in a pre-bonded state at a predetermined position of the base member 42 before construction.

[0044] <Step 3: Fixing of the base member> Next, the fastener M1 is inserted through the receiving seat 50 and the base member 42 and screwed into the wooden structure X. In this case, since the screw hole 52a (first insertion hole) formed in the inclined portion 52 of the receiving seat 50 penetrates substantially perpendicular to the surface of the inclined portion 52, the screw portion m11 of the fastener M1 is guided and inserted along this screw hole 52a. As a result, the fastener M1 is driven in (screwed in) obliquely with respect to the finding surface Xa of the wooden structure X and screwed, so that the base member 42 is firmly fixed to the wooden base x1 of the wooden structure X, and thus, the guide rail 40A can be stably and reliably attached and fixed.

[0045] Note that a washer may be provided between the head m12 of the fastener M1 and the receiving seat 50 so that the fastener M1 is screwed in. Further, an insertion hole through which the threaded portion m11 is inserted may be formed in the plate-shaped portion 42a of the base member 42 by a general-purpose tool such as an electric drill during construction.

[0046] <Step 4: Installation of the Rail Body> Next, the rail body 41 is attached to the base member 42 fixedly attached to the finding surface Xa of the wooden structure X. The rear end portion of the rail body 41 is overlapped with the respective protruding pieces 42b, 42b of the base member 42 and integrally joined by a fastener (for example, a screw, a bolt, a rivet, etc.) not shown. Thereby, a closed space S (air layer) defined by the rail body 41 and the base member 42 is formed in the guide rail 40A (see FIG. 3).

[0047] <Step 5: Arrangement of the Fire-Resistant Member> Next, the fire-resistant member x3 is arranged on the surface inside the opening / closing body width direction of the guide rail 40A. In this case, the fire-resistant member x3 can be attached and fixed to the guide rail 40A by fixing means (not shown) such as screws or bolts, or a heat-resistant / fire-resistant adhesive or adhesive material.

[0048] According to the above configuration, in the construction of the guide rail 40A, the fastener M1 is driven obliquely (screwed) into the wooden base x1 of the wooden structure X with respect to the finding surface Xa of the wooden structure X via the receiving seat 50, so that the pull-out resistance of the fastener M1 is improved. Therefore, the guide rail 40A can be firmly fixed to the wooden structure X (strongly fixed against an external force), and it is possible to suppress the fastener M1 from falling off or the pivot bracket 30 from coming off due to the falling off of the fastener M1 during a fire.

[0049] Even when the base member 42 is disposed at a position shifted left and right in the width direction of the wooden base x1, since the fastener M1 is screwed in an inclined state with respect to the finding surface Xa (mounting surface) of the wooden structure X, the screw portion m11 of the fastener M1 can be screwed toward the central portion of the wooden base x1. Therefore, for example, as shown in FIG. 3, when the narrow guide rail 40A is disposed on the wooden base x1, the base member 42 of the guide rail 40A may be disposed at a position shifted left and right in the width direction of the wooden base x1 (FIG. 3 shows an example disposed to the left with respect to the wooden base x1). However, since the screw portion m11 of the fastener M1 can be screwed toward the central portion of the wooden base x1 via the receiving seat 50, when the fastener M1 is screwed in, it is possible to prevent the fastener M1 from splitting the wooden base x1, and the base member 42 can be firmly fixed to the wooden structure X.

[0050] Further, in the present embodiment, since a part of the head m12 and the shaft portion of the fastener M1 is located in the closed space S (air layer) of the guide rail 40A, when heat is received from the outside of the guide rail 40A due to a fire, the heat can be blocked from being transmitted to the fastener M1 by this space S (air layer). Therefore, it is also possible to prevent the wooden structure X from being thermally deteriorated (damaged) around the screw portion m11 of the fastener M1.

[0051] (Second Embodiment) Next, another embodiment of the fixing structure of the opening / closing device according to the present invention will be described. FIG. 8 is a schematic cross-sectional view along the line (IV)-(IV) of FIG. 1, showing another example (fixing structure of the shaft support bracket) of the fixing structure of the opening / closing device according to the present invention. FIG. 9 is a perspective schematic view of the shaft support bracket shown in FIG. 8, and FIG. 10 is a perspective schematic view showing a state in which a fastener is attached to the shaft support bracket shown in FIG. 9. Further, FIG. 11(a) is a plan schematic view of the shaft support bracket shown in FIG. 10, FIG. 11(b) is a side schematic view of the shaft support bracket shown in FIG. 10, and FIG. 11(c) is a front schematic view of the shaft support bracket shown in FIG. 10.

[0052] (Installation of Shaft Support Bracket) As shown in Fig. 8, a pair of left and right pivot brackets 30 as components of the opening and closing device 1 are fixed to the locating surface Xa (mounting surface) of the wooden structure X by a fastener M1 inserted through the mounting portion 33 of the pivot bracket 30. As shown in Fig. 9, each pivot bracket 30 includes, for example, a flat support body 31, upper and lower flange portions 32, 32 bent outward in the left-right direction from the upper and lower edges of the support body 31, and a mounting portion 33 bent inward in the left-right direction from the rear edge of the support body 31. Each pivot bracket 30 is integrally formed, for example, by bending a flat metal plate or welding each part.

[0053] Although Figs. 8 and 9 show the pivot bracket 30 arranged on one side (right side) in the left-right direction of the shutter device 1, the pivot bracket 30 arranged on the other side (left side) in the left-right direction is also configured in the same way (symmetrical structure).

[0054] As shown in Fig. 9, a notch 31a for inserting the shaft portion 21a of the winding shaft 21 is formed in the support body 31 of the pivot bracket 30. This notch 31a is formed so as to form a recess opening forward of the pivot bracket 30. The shaft portion 21a of the winding shaft 21 is rotatably supported in this notch 31a via a bearing member (not shown) fixed inside the pivot bracket 30 with a fastener such as a screw.

[0055] The mounting portion 33 of the pivot bracket 30 forms a mounting portion for the wooden structure X and is attached and fixed to the wooden structure X using the fastener M1. The mounting portion 33 has a substantially rectangular shape (substantially rectangular shape) in a front view, and a central insertion hole 33a for inserting the fastener M1 is formed substantially at the center in the vertical direction. This central insertion hole 33a is formed to penetrate substantially perpendicular to the surface of the mounting portion 33. The fastener M1 inserted through this central insertion hole 33a is driven (screwed) and screwed in a substantially perpendicular state (orthogonal state) with respect to the locating surface Xa of the wooden structure X.

[0056] Further, at each upper and lower end of the mounting portion 33, as seating portions, an upper receiving seat 34 and a lower receiving seat 35 are formed by raising a part thereof. The upper receiving seat 34 extends obliquely upward at a predetermined angle (acute angle) with respect to the upper surface of the mounting portion 33. Also, the lower receiving seat 35 extends obliquely downward at a predetermined angle (acute angle) with respect to the upper surface of the mounting portion 33.

[0057] The upper receiving seat 34 and the lower receiving seat 35 can be formed, for example, by forming slits (notches) such as substantially V-shaped, substantially U-shaped, substantially arc-shaped, substantially C-shaped, etc. in a part of the mounting portion 33, and raising the portion surrounded by this slit (notch) to have a predetermined inclination angle.

[0058] The inclination angles of the upper surfaces of the upper receiving seat 34 and the lower receiving seat 35 with respect to the mounting portion 33 (the inclination angles with respect to the upper surface of the mounting portion 33 and the inclination angles with respect to the finding surface Xa) can be set to any angle (acute angle) that can firmly fix the pivot bracket 30 to the wooden housing X (strongly fixed against external forces), and although not particularly limited, for example, by setting it to 10 to 30 degrees, the workability during the installation of the pivot bracket 30 (for example, when screwing in the fastener M1) can be improved.

[0059] At approximately the center of the upper receiving seat 34 and the lower receiving seat 35, an upper insertion hole 34a and a lower insertion hole 35a for inserting the fastener M1 are respectively formed, and the peripheral portion surrounding these insertion holes 34a, 35a (the first insertion holes) is configured to receive the head m12 of the fastener M1. Since these insertion holes 34a, 35a are substantially equal to the outer diameter of the threaded portion m11 of the fastener M1 and penetrate substantially perpendicularly to the surfaces of the respective receiving seats 34, 35, the threaded portion m11 of the fastener M1 will be inserted along these insertion holes 34a, 35a. As a result, the fastener M1 is driven in (screwed in) obliquely with respect to the finding surface Xa of the wooden housing X and screwed together.

[0060] That is, the fastener M1 inserted into the upper insertion hole 34a of the upper seat 34 is driven obliquely upward with respect to the finding surface Xa of the wooden structure X. Specifically, as shown in FIGS. 11(b) and (c), it is inclined upward at an acute inclination angle β1 with respect to the horizontal plane H passing through the head m12, and is inclined upward at an acute inclination angle β2 with respect to the vertical plane V passing through the head m12 and then driven in.

[0061] Also, the fastener M1 inserted into the lower insertion hole 35a of the lower seat 35 is driven obliquely downward with respect to the finding surface Xa of the wooden structure X. Specifically, as shown in FIGS. 11(b) and (c), it is inclined downward at an acute inclination angle β1 with respect to the horizontal plane H passing through the head m12, and is inclined downward at an acute inclination angle β2 with respect to the vertical plane V passing through the head m12 and then driven in. Therefore, the pivot bracket 30 can be firmly fixed to the wooden structure X (strongly fixed against external forces).

[0062] When attaching the pivot bracket 30 to the wooden structure X, the pivot bracket 30 is arranged on the finding surface Xa (attachment surface) of the wooden structure X (the attachment portion 33 is abutted), and the fastener M1 is inserted into the respective insertion holes 33a, 34a, 35a formed in the attachment portion 33 of the pivot bracket 30 and then screwed in. In this case, for example, first insert the fastener M1 into the central insertion hole 33a (second insertion hole) formed approximately at the center in the vertical direction of the attachment portion 33 and lightly screw it into the wooden structure X. Then, the pivot bracket 30 can be rotated around the fastener M1 inserted into the central insertion hole 33a to easily adjust the attachment position.

[0063] Next, after the attachment position of the pivot bracket 30 is determined, tighten the fastener M1 that was lightly screwed in, and insert and screw the fastener M1 into the insertion holes 34a, 35a (second insertion holes) formed in the upper and lower seats 34. Thereby, the pivot bracket 30 is firmly fixed to the wooden structure X.

[0064] According to the above configuration, the fastener M1 inserted into the central insertion hole 33a (second insertion hole) of the support bracket 30 is screwed in a state substantially perpendicular to the finding surface Xa of the wooden structure X, and the fastener M1 inserted into the upper insertion hole 34a (first insertion hole) is screwed obliquely upward with respect to the finding surface Xa of the wooden structure X, and the fastener M1 inserted into the lower insertion hole 35a (first insertion hole) is screwed obliquely downward with respect to the finding surface Xa of the wooden structure X. Since the driving directions of the respective fasteners M1 are different, the support bracket 30 can be firmly fixed to the wooden structure X (strongly fixed against external forces), and during a fire, it is possible to suppress the fastener M1 from falling off or the support bracket 30 from becoming detached due to the falling off of the fastener M1.

[0065] (Modification example) Next, a modification example of the above embodiment will be described. Since the modification example described below is a modification of a part of the configuration of the above embodiment, mainly the modified part will be described, and the same components will be denoted by the same reference numerals and redundant descriptions will be omitted.

[0066] [Modification example 1] FIG. 12 shows a schematic cross-sectional view showing a modification example (modification example 1) of the above embodiment 2. This modification example 1 is configured by partially changing the arrangement mode of the wooden base x1 in the above embodiment 2 (see FIG. 8) and the structure of the mounting portion 33 of the support bracket 30.

[0067] Specifically, a plurality (two in the illustrated example) of wooden bases x1 of the wooden structure X are provided, and the support bracket 30' is configured to be attached and fixed to the wooden structure X via a receiving seat 50' provided on the upper surface of the mounting portion 33' of the support bracket 30'.

[0068] The mounting portion 33' of the support bracket 30' is formed in a substantially flat plate shape, and a plurality of receiving seats 50' formed in the same manner as the receiving seat 50 shown in FIG. 5 are spaced apart and arranged on the upper surface of this mounting portion 33'. The receiving seat 50' has the same structure as the short receiving seat 50 shown in FIGS. 5 and 6(a), and includes a rising portion 51, an inclined portion 52, and a flat plate portion 53 (the first contact portion). The difference in structure is that a screw hole (not shown) for inserting the screw portion m11 of the fastener M1 is formed substantially in the center of the flat plate portion 53 and penetrates substantially perpendicular to the surface of the flat plate portion 53, with a diameter substantially equal to the outer diameter of the screw portion m11 of the fastener M1.

[0069] Also, the length from the outer surface of the rising portion 51 of the receiving seat 50' to the end surface of the flat plate portion 53 is formed to be substantially the same as or smaller than the finding direction length (the left-right direction length in FIG. 12) of the mounting portion 33' of the pivot bracket 30'. Therefore, when the rising portion 51 of the receiving seat 50' is arranged in contact with the support body 31 of the pivot bracket 30', the receiving seat 50' is arranged so as to fit without protruding from the mounting portion 33'.

[0070] According to this Modification 1, the fastener M1 inserted through the insertion hole (not shown) formed in the flat plate portion 53 of the receiving seat 50' is driven (screwed) in a substantially perpendicular state with respect to the finding surface Xa of the wooden structure X as shown in FIG. 12 and is screwed. Also, the fastener M1 inserted through the insertion hole (not shown) formed in the inclined portion 52 of the receiving seat 50' is driven (screwed) obliquely with respect to the finding surface Xa of the wooden structure X and is screwed.

[0071] Therefore, also in this Modification 1, the pivot bracket 30 can be firmly fixed to the wooden structure X (strongly fixed against external forces), so that during a fire, it is possible to prevent the fastener M1 from falling off or the pivot bracket 30' from becoming detached due to the falling off of the fastener M1.

[0072] [Modification 2] FIG. 13 shows a schematic cross-sectional view showing a modification (Modification 2) of the above-described Embodiment 1. This Modification 2 is configured by partially changing the structure for fixing the base member 42 of the guide rail 40A in the above-described Embodiment 1 (see FIG. 3).

[0073] Specifically, similar to the above-described Embodiment 1, the fastener M1 (shown by the solid line in FIG. 13) is driven (screwed) obliquely into the finding surface Xa of the wooden structure X via the receiving seat 50 and screwed into the wooden base x1 of the wooden structure X. Further, the screw portion m11 of the fastener M1 (shown by the dotted line in FIG. 13) is inserted into a screw hole (not shown) formed in the plate-shaped portion 42a of the base member 42 and penetrating substantially vertically, and screwed in a substantially vertical state with respect to the finding surface Xa of the wooden structure X. In this case, a plurality of receiving seats 50 are arranged at predetermined intervals along the longitudinal direction of the base member 42, and the fastener M1 may be inserted and screwed into the screw holes (not shown) formed in each receiving seat 50 and the screw holes (not shown) formed in the portion of the plate-shaped portion 42a located between the receiving seats 50.

[0074] According to this Modification 2, the fastener M1 inserted into the insertion hole (not shown) formed in the plate-shaped portion 42a of the base member 42 is driven and screwed in a substantially vertical state with respect to the finding surface Xa of the wooden structure X, and the fastener M1 inserted into the insertion hole (not shown) formed in the inclined portion 52 of the receiving seat 50 is driven and screwed obliquely with respect to the finding surface Xa of the wooden structure X.

[0075] Therefore, also in this Modification 2, the guide rail 40B can be firmly fixed to the wooden structure X (strongly fixed against external forces), so that it is possible to suppress the fastener M1 from falling off or the guide rail 40B from coming off due to the fall of the fastener M1 during a fire.

[0076] [Modification 3] FIG. 14 shows a schematic cross-sectional view showing a modification (Modification 3) of the above-described Embodiment 1. This Modification 3 is configured to fix the base member 42 to the finding surface Xa of the wooden structure X without using the receiving seat 50 of the above-described Embodiment 1 (see FIG. 3).

[0077] Specifically, the plate-like portion 42a of the base member 42 of the guide rail 40C forms a substantially flat plate-like (flat) contact portion that contacts the finding surface Xa of the wooden structure. A plurality of insertion holes (not shown) are formed in the plate-like portion 42a at predetermined intervals in the longitudinal direction of the base member 42 (the vertical direction in FIGS. 1 and 2). These insertion holes include a first insertion hole (not shown) drilled obliquely from one surface of the plate-like portion 42a toward the other surface with respect to the plate-like portion 42a, and a second insertion hole (not shown) drilled substantially perpendicularly from one surface of the plate-like portion 42a toward the other surface with respect to the plate-like portion 42a.

[0078] In addition, in FIG. 14, the fastener M1 inserted and guided along the first insertion hole is shown by a dotted line, and the fastener M1 inserted and guided along the second insertion hole is shown by a solid line. Also, this guide rail 40C is formed wider than the guide rail 40A (see FIG. 3) of the above-described embodiment.

[0079] Since the first insertion hole functions as a guiding means for guiding the shaft portion of the fastener M1 (dotted line in FIG. 14) in an oblique direction with respect to the finding surface Xa (mounting surface) of the wooden structure X, the shaft portion of the fastener M1 is inserted and guided along the first insertion hole, and thus is driven (screwed) obliquely with respect to the finding surface Xa (mounting surface) of the wooden structure X and screwed into the wooden base x1 of the wooden structure X.

[0080] Also, since the second insertion hole is drilled substantially perpendicularly from one surface of the finding surface Xa (mounting surface) of the wooden structure X toward the other surface with respect to the finding surface Xa (mounting surface), the fastener M1 (solid line in FIG. 14) inserted and guided along the second insertion hole is driven in a substantially perpendicular state with respect to the finding surface Xa (mounting surface) of the wooden structure X and screwed into the wooden base x1 of the wooden structure X.

[0081] Also in this modification 3, since the guide rail 40C as a component of the opening / closing device 1 can be firmly fixed to the wooden structure X (strongly fixed against external forces), it is possible to suppress the fastener M1 from falling off or the guide rail 40C from coming off due to the falling off of the fastener M1 during a fire.

[0082] [Modification Example 4] FIG. 15 is a schematic cross-sectional view showing another example (the fixing structure of the guide rail) of the fixing structure of the opening / closing device according to the present invention. In this fixing structure, a guide rail 40D is installed on the prospective surface Xb (mounting surface) of the opening of the wooden housing X. The guide rail 40D constitutes an opening / closing device (not shown) in substantially the same manner as in the above-described embodiment, and guides the widthwise end portions of the opening / closing body 10 drawn out from the upper storage portion 20 in the vertical direction while surrounding them in a concave shape.

[0083] The guide rail 40D is composed of a rail main body 41 protruding from the prospective surface Xb of the wooden housing X toward the inner side in the width direction of the opening / closing body (left side according to FIG. 15), and a base member 42 for fixing the rail main body 41 to the prospective surface Xb.

[0084] The rail main body 41 of the guide rail 40D integrally has a guide portion 41a for guiding the opening / closing body 10 in the vertical direction, and a support portion 41b protruding from the prospective surface Xb of the wooden housing X toward the inner side in the width direction of the opening / closing body to support the guide portion 41a, and is continuously formed in a long shape extending in the vertical direction. The support portion 41b of the guide rail 40D forms an air layer S closed together with the base member 42.

[0085] The rail main body 41 of the guide rail 40D is integrally joined to the previously fixed base member 42 by overlapping the inner surface of the support portion 41b and using a fixing tool (for example, a screw, a bolt, a rivet, etc.) not shown. Note that the upper end side and the lower end side of the guide rail 40D are respectively fixed to immovable portions. Further, the outer surfaces of the front and rear of the guide rail 40D may be configured to be covered with a single-layer or multi-layer refractory member x2.

[0086] The base member 42 has a substantially concave cross section having a plate-like portion 42a in contact with the prospective surface Xb of the wooden housing X, and protruding pieces 42b, 42b protruding from both end portions in the prospective direction of the plate-like portion 42a toward the inner side in the width direction of the opening / closing body (left side according to FIG. 15), and is continuously formed in a long shape extending in the vertical direction. The base member 42 is fixedly attached to the prospective surface Xb of the wooden structure X by a fastener M1 via a receiving seat 60 as guiding means.

[0087] The receiving seat 60 functions as guiding means for guiding the shaft portion m11 of the fastener M1 in an inclined direction with respect to the prospective surface Xb (mounting surface) of the wooden structure X, and is configured to drive the fastener M1 obliquely into the prospective surface Xb of the wooden structure X. This receiving seat 60 has, for example, as shown in FIGS. 16(a), (b) and 17(a), a rising portion 61 extending substantially perpendicularly to the plate-like portion 42a of the base member 42, a first flat plate portion 63 (first abutting portion) extending along the plate-like portion 42a of the base member 42, an inclined portion 62 connected to one end edge of the rising portion 61 and one end edge of the first flat plate portion 63, and a second flat plate portion 64 (second abutting portion) extending along the plate-like portion 42a of the base member 42 and connected to the other end edge of the rising portion 61, and is formed, for example, by bending a flat plate-shaped metal plate.

[0088] FIGS. 16(a), (b) and 17(a) show a short receiving seat 60 configured to be able to insert one fastener M1. In the illustrated example, the inclined portion 62 is set such that the vertical and horizontal dimensions are substantially the same, and is formed in a substantially square shape when viewed from the front. A screw hole 62a for inserting the screw portion m11 of the fastener M1 is formed substantially at the center of the inclined portion 62. The peripheral portion surrounding this screw hole 62a is configured to receive the head m12 of the fastener M1.

[0089] The screw hole 62a is substantially equal to the outer diameter of the screw portion m11 of the fastener M1 and is formed to penetrate substantially perpendicularly to the surface of the inclined portion 62. The screw portion m11 of the fastener M1 is inserted along this screw hole 62a, and as a result, the fastener M1 is driven (screwed) obliquely into the prospective surface Xb of the wooden structure X.

[0090] For example, when a plurality of receiving seats 60 are arranged at predetermined intervals along the longitudinal direction of the base member 42, as shown in FIGS. 15(a) and 15(b), by arranging the inclined portions 62 of adjacent receiving seats 60 to incline in different directions from each other, the fasteners M1 can be driven (screwed) in different directions respectively. Therefore, the guide rail 40A can be firmly fixed to the wooden housing X (strongly fixed against external forces).

[0091] Further, in this receiving seat 60, a rising portion 61 and an inclined portion 62 are located between a first flat plate portion 63 (first abutting portion) and a second flat plate portion 64 (second abutting portion), and the first flat plate portion 63 and the second flat plate portion 64 can be surface - contacted with the upper surface of the plate - like portion 42a of the base member 42 and stably installed, improving the workability during the installation of the guide rail 40D.

[0092] Also, as shown in FIG. 17(b), the receiving seat 60 may be configured as a long - shaped receiving seat 60' through which a plurality of fasteners M1 can be inserted. This long - shaped receiving seat 60' is configured as a long - shaped receiving seat in which the length in the orthogonal direction orthogonal to the inclination direction of the inclined portion 62 is longer than the length in the inclination direction of the inclined portion 62.

[0093] A plurality of screw holes 62a (first insertion holes) are formed at predetermined intervals along the orthogonal direction orthogonal to the inclination direction of the inclined portion 62 in the inclined portion 62. Note that this long - shaped receiving seat 60' also has a rising portion 61, an inclined portion 62, a first flat plate portion 63, and a second flat plate portion 64 formed in the same manner as the above - described short - shaped receiving seat 60, and the same components are denoted by the same reference numerals and redundant descriptions are omitted.

[0094] [Modification Example 5] FIG. 18 is a schematic perspective view showing another example (Modification Example 5) of a fixture (receiving seat) in the fixing structure according to the present invention. The receiving seat 70 constituting the fixture of Modification Example 5 has a plurality of inclined portions 72 (72A, 72B, 72C), and these inclined portions 72 (72A, 72B, 72C) are integrally formed by being connected in plurality at predetermined intervals in the orthogonal direction orthogonal to the inclination direction of the inclined portion.

[0095] Specifically, rising portions 71 (71A, 71B, 71C) that extend substantially perpendicularly to the upper surface of the plate-like portion 42a of the guide rails 40A, 40B, 40D and the upper surface of the mounting portion 33 of the pivot bracket 30' are respectively connected to one end edge of the plurality of inclined portions 72 (72A, 72B, 72C), and each short receiving seat is formed by each inclined portion 72 and each rising portion 71.

[0096] And each of the single-scale receiving seats is connected and integrated in a state of being separated by a predetermined interval in a direction orthogonal to the inclination direction of the inclined portion 72, and in a state where adjacent inclined portions are inclined in different directions (alternately) so as to form a receiving seat 70. Each of the short receiving seats can be connected and integrated, for example, by a pair of flat plate portions 73, 74 extending in a direction orthogonal to the inclination direction of the inclined portion 72. In the illustrated example, the three short receiving seats are arranged alternately in the order of the inclined portion 72A inclined to the lower left side, the inclined portion 72B inclined to the lower right side, and the inclined portion 72C inclined to the lower left side, and are connected and integrated in a manner sandwiched between the pair of flat plate portions 73, 74.

[0097] Also, screw holes 72Aa, 72Ba, 72Cc (first insertion holes) that are substantially equal to the outer diameter of the screw portion m11 of the fastener M1 and penetrate substantially perpendicularly to the surfaces of the inclined portions 72A, 72B, 72C are respectively formed at substantially the central portions of the inclined portions 72A, 72B, 72C of each short receiving seat, and are configured to drive (screw in) the fastener M1 obliquely and threadedly engage with the mounting surface (the finding surface Xa, the prospective surface Xb) of the wooden housing X.

[0098] Also, the pair of flat plate portions 73, 74 extend along the upper surfaces of the plate-like portions 42a of the guide rails 40A, 40B, 40D and the upper surface of the mounting portion 33 of the pivot bracket 30', and function as abutting portions that can abut against the upper surfaces.

[0099] Note that the number of each short receiving seat arranged on the receiving seat 70 is not limited to the above example and can be set to any number. Also, each short receiving seat is arranged in a state of being sandwiched between a pair of flat plate portions 73 and 74, but it is not limited to such a structure. For example, it may be configured to be connected only by one of the pair of flat plate portions 73 and 74.

[0100] Also in the fixture of this modification 5, the constituent members of the opening / closing device (such as guide rails and shaft support brackets) can be firmly fixed to the wooden housing X (strongly fixed against external forces). Therefore, during a fire, it is possible to suppress the detachment of the fastener M1 or the detachment of the constituent members of the opening / closing device due to the detachment of the fastener M1.

[0101] Further, the receiving seat 70 has each short receiving seat positioned between a pair of flat plate portions 73 and 74, and the pair of flat plate portions 73 and 74 can be installed stably with surface contact at the installation position. Therefore, the workability during the installation of the opening / closing device is improved.

[0102] Note that the receiving seat 70 arranges a plurality of short receiving seats such that the inclined portions of adjacent short receiving seats are inclined in different directions from each other (arranged alternately). However, it is also possible to configure by arranging the plurality of short receiving seats such that the inclined portions of each short receiving seat are inclined in the same direction.

[0103] Note that the present invention is not limited to the above-described specific configuration and can be appropriately changed without changing the gist of the present invention.

[0104] For example, in Modification 1 shown in FIG. 12, the support bracket 30' is configured to be attached and fixed to the wooden structure X via a receiving seat 50' installed on the upper surface of the attachment portion 33' of the support bracket 30'. However, it may be configured to fix the attachment portion 33' to the finding surface Xa of the wooden structure X without using this receiving seat 50'. In this case, similar to Modification 3 shown in FIG. 14, the attachment portion 33' may include a first insertion hole drilled obliquely from one side surface of the attachment portion 33' toward the other side surface, and a second insertion hole drilled substantially perpendicularly from one side surface of the attachment portion 33' toward the other side surface.

[0105] Also, for example, in Modification 3 shown in FIG. 14, first insertion holes and second insertion holes are formed in the plate-like portion 42a of the base member 42 of the guide rail 40C at predetermined intervals along its longitudinal direction. However, this first insertion hole may be formed in the raised portions (upper receiving seat 34, lower receiving seat 35) as shown in FIGS. 9 to 11. In this case, a raised portion raised at a predetermined angle along the longitudinal direction of the plate-like portion 42a is formed, and a first insertion hole drilled substantially perpendicularly from one side surface of the raised portion toward the other side surface is provided in this raised portion. Also, a second insertion hole drilled substantially perpendicularly may be provided in a portion other than the raised portion.

[0106] Also, in the embodiment shown in FIG. 9, the upper receiving seat 34 and the lower receiving seat 35 as seat portions are formed by forming slits (notches) such as substantially V-shaped, substantially U-shaped, substantially arc-shaped, and substantially C-shaped in a part of the attachment portion 33, and raising the portion surrounded by this slit (notch) to a predetermined inclination angle. However, the present invention is not limited to this configuration. For example, the seat portion may be formed as a convex portion having an inclined portion (seat surface) inclined at a predetermined angle with respect to the upper surface of the attachment portion 33 by drawing (press working).

[0107] Also, although the above-described embodiments and modifications have been described as the fixing structure and fixture of the guide rail and the support bracket constituting the opening and closing device, they are applicable as the fixing structure and fixture of any constituent member constituting the opening and closing device.
