Summary of the Invention

Problems to be Solved by the Invention

[0004] However, according to the above prior art, there is a risk that the fastener may loosen or fall out due to aging deterioration or the like. In particular, in recent years, due to relaxation of regulations on large-scale buildings in the Building Standards Law, etc., the installation of heavy shutters at the openings of large wooden buildings has increased. In such cases, if a heavy guide rail or shutter box is fixed to a wooden base material or the like, the possibility of loosening or falling out of the fastener increases due to aging deterioration of the wood constituting the base material.

Means for Solving the Problems

[0005] In view of these challenges, one aspect of the present invention comprises the following configuration. An opening and closing device installation structure is provided in which an opening and closing device for opening and closing an opening is fixed to a wooden columnar base member provided on the side of the opening, wherein at least the surface on the visible side of the columnar base member is covered by a covering member that is more rigid than the columnar base member, and the opening and closing device is fixed to the columnar base member via the covering member. [Effects of the Invention]

[0006] As described above, the present invention is configured in such a way that it can improve the durability of the fastening portion of the opening and closing device. [Brief explanation of the drawing]

[Figure 8] Another example of the opening / closing device installation structure according to the present invention is shown, where (a) is a cross-sectional view of the main part and (b) is a longitudinal cross-sectional view of the main part. [Modes for carrying out the invention]

[0008] Next, embodiments of the present invention will be described in detail with reference to the drawings. In the following explanation, "visible surface" refers to the surface located on the front side when the opening a, which is opened and closed by the opening / closing device 10, is viewed from the front. Furthermore, "viewing surface" refers to the surface that extends towards the back of the opening a when the opening a, which is opened and closed by the opening / closing device 10, is viewed from the front.

[0009] <Opening / closing device installation structure A> The opening / closing device installation structure A shown in Figure 1 fixes the opening / closing device 10, which opens and closes the opening a, to wooden columnar base members 21 provided on the left and right sides of the opening a. At least a portion of the surface of each columnar base member 21 is covered by a covering member 40.

[0010] In a large wooden building, opening a is a rectangular opening in front view that penetrates the wall 20. The wall portion 20 surrounding this opening a is composed of columnar base members 21 erected on both the left and right sides of the opening a, wall material 22 that surrounds each columnar base member 21, and so on.

[0011] The columnar base member 21 is a rectangular columnar member made of wooden timber or the like, and is fixed immovably to the building on which the opening / closing device 10 is to be installed. This columnar base member 21 supports the wall material 22 from the inside and is sometimes referred to as a base material or the like.

[0012] The wall material 22 is, for example, a fire-resistant wall material such as gypsum board, and appropriately covers the surrounding area of ​​the columnar base member 21 (see Figure 2(a)). This wall material 22 is provided in a multi-layered structure (two layers in the illustrated example) from the viewpoint of improving fire resistance, but it can also be made in a single layer. Furthermore, between the front wall materials 22,22 and the back wall materials 22,22, if necessary, base materials, insulation materials, etc. (not shown) may be provided.

[0013] The opening / closing device 10 includes an opening / closing body 11 that opens and closes in the vertical direction along the opening a, a guide rail 12 that guides the end side in the lateral width direction of the opening / closing body 11 in the opening / closing direction, and a storage portion 13 that stores the opening / closing body 11 on the opening side (see FIG. 1), and is fixed to the columnar base member 21 via a covering member 40.

[0014] The opening / closing body 11 is formed by connecting a plurality of slats formed by bending a horizontally long substantially rectangular metal plate so as to rotate between adjacent slats in the vertical direction, and a seat plate member for abutting against an abutting target portion in the closing direction (for example, a floor surface, a ground surface, a frame member, etc.) is connected to the lower ends of these slats.

[0015] The guide rail 12 integrally includes a rail main body 12a that guides the end side in the lateral width direction of the opening / closing body 11 in the opening / closing direction, and a separate base member 12b connected to the rail main body 12a by a fastener 12c (for example, a screw or a bolt, etc.) (see FIG. 2). This guide rail 12 extends in the vertical direction along the surface on the finding surface side of the covering member 40 (the covering piece 41 on the finding surface side).

[0016] The rail main body 12a is formed in a substantially concave cross-section that surrounds the end portion in the lateral width direction of the opening / closing body 11 with a hard metal material, and is continuously formed in a long shape in the vertical direction. \n

[0017] The base member 12b is formed in a long shape that is substantially the same length as the rail main body 12a and is continuous in the vertical direction with a hard metal material. The base member 12b in the illustrated example is formed in a concave cross-section, overlaps the covering member 40 with its bottom wall portion, and overlaps the rail main body 12a by protruding the side wall portions on both sides forward. A plurality of through holes 12b1 (see FIG. 3(b)) for loosely inserting the male member 31 and the female member 32 are provided at intervals in the vertical direction in the bottom wall portion. Further, through holes (specifically, female screw holes or pilot holes for tapping screws) for screwing the fastener 12c are provided in the side wall portions. This base member 12b is welded to the visible side covering piece 41 of the covering member 40 with the male member 31 and female member 32 inserted through the through hole 12b1 (see Figure 3(b)).

[0018] In addition, other means of fixing the base member 12b to the visible side covering piece 41 include joining the male member 31 and the female member 32, or fastening with fasteners (such as screws or rivets) not shown.

[0019] The rail body 12a is then attached to this base member 12b by fasteners 12c (see Figure 3). Furthermore, in the figure, reference numeral 12d denotes a reinforcing member that reinforces the rail body 12a, and is fixed within the rail body 12a by appropriate fixing means. The fixing means can be, for example, welding, adhesive, screw fastening, riveting, fitting, or a combination thereof. Note that this reinforcing member 12d can be omitted.

[0020] The storage section 13 consists of a winding shaft 13a that winds up and unwinds the opening / closing body 11, a storage case 13b that covers the winding shaft 13a, and an opening / closing mechanism (not shown) that drives the winding shaft 13a to rotate in the winding direction. The winding shaft 13a causes the opening / closing body 11 to close downwards or open upwards.

[0021] The covering member 40 is formed from a metal plate that is harder and more rigid than the columnar base member 21, so as to cover at least the surface of the columnar base member 21 on the visible side. The covering member 40 in the illustrated example is formed in a roughly U-shape (or, to put it another way, a roughly concave cross-section) from a covering piece 41 on the visible side of the columnar base member 21, a covering piece 42 on the hidden side of the columnar base member 21, and a covering piece 43 on the opposite side of the columnar base member 21 to the visible side, and is continuous from top to bottom so as to cover the columnar base member 21 from three sides. In the illustrated example, the covering member 40 is designed so that the length of the covering piece 43 on the side opposite the visible surface (the left-right direction in Figure 2(a)) is shorter than the length of the covering piece 41 on the visible surface side in the same direction, so that the exposed surface on the side opposite the visible surface of the columnar base member 21 supports the inner wall material 22.

[0022] The visible-side covering piece 41 and the non-visible-side covering piece 43 are each provided with through-holes 41a and 43a for inserting the male member 31 (see Figure 3(a)).

[0023] The vertical length of the covering member 40 is set to be a partial length relative to the total length of the columnar base member 21, and to include a plurality of male members 31, 31. As an alternative example, the length of the covering member 40 may be approximately equal to the length of the columnar base member 21.

[0024] The male member 31 is a bolt having a head on its rear end and a male threaded portion on its front end. Multiple bolts 31 are arranged at intervals in the vertical direction. Furthermore, the female member 32 has its inner circumferential threaded portion screwed onto the male threaded portion at the tip of each bolt 31. Furthermore, the male member 31 and the female member 32 can be any type that fits together in a male-female configuration for fastening; for example, a rivet and a rivet nut fastened to the rivet are also possible.

[0025] Each male member 31 is inserted through the wall portion 20 from the back side (in other words, the back side in the viewing direction) into the anti-visible surface covering piece 43, the columnar base member 21, and the visible surface covering piece 41. A female member 32 is then screwed onto and tightened to the tip of each male member 31.

[0026] The following describes the construction method for the above-mentioned opening / closing device installation structure A. First, the covering member 40 is fitted onto the columnar base member 21 from the side (opening a side) (see Figure 3(b)).

[0027] Next, a through hole 21a is formed in the columnar base member 21 so as to communicate with the insertion holes 41a and 43a of the visible-side covering piece 41 and the non-visible-side covering piece 43. This through hole 21a can be drilled using a general-purpose tool such as an electric drill.

[0028] Next, the base member 12b is welded to the visible surface side covering piece 41 of the covering member 40 so that the through hole 12b1 of the base member 12b and the insertion hole 41a of the visible surface side covering piece 41 are in communication.

[0029] The through-hole 12b1 in the base member 12b may be pre-drilled in a factory or elsewhere, or it may be drilled on-site when aligning the guide rail 12.

[0030] Next, the rail body 12a is fitted onto the base member 12b. Then, the rail body 12a and the base member 12b are joined together by the fastener 12c (see Figure 3).

[0031] Then, the exposed portions around the columnar base member 21 and the covering member 40 are covered by the wall material 22. Furthermore, the inner wall material 22 on the rear side is provided with a through-hole 22a to allow the head of the male member 31 to pass through.

[0032] Therefore, according to the opening / closing device installation structure A and its construction method described above, the columnar base member 21 can be reinforced with the covering member 40, thereby improving the durability of the fastening portion of the guide rail 12. For this reason, even if the wooden columnar base member 21 deteriorates, a decrease in the strength of the fastening portion can be prevented.

[0033] <Switching device installation structure B> In the opening / closing device installation structure B shown in Figure 4, the storage section 13, which is a part of the opening / closing device 10, is fixed to the columnar base member 21 via a covering member 40. This opening / closing device installation structure B is configured in which the guide rail 12 is replaced with a storage case 13b in the opening / closing device installation structure A described above.

[0034] The storage case 13b is formed in a horizontally elongated rectangular shape to house the winding shaft 13a that has the opening / closing body 11 wound up, and has mounting brackets 13b1 (see Figure 4) that protrude in the depth direction on its left and right ends, respectively. Each mounting bracket 13b1 is bent at its protruding end into an inverted L-shape in cross-section, and a through hole is provided in this bent portion for inserting the male member 31.

[0035] The male member 31, which penetrates the covering member 40 and the columnar base member 21, has its tip inserted into the mounting bracket 13b1. The female member 32 is then screwed onto the tip of the male member 31 and tightened.

[0036] Therefore, even in the opening / closing device installation structure B, it is possible to prevent a decrease in strength and improve durability of the fastening portion of the relatively heavy storage section 13.

[0037] <Switching device installation structure C> The opening / closing device installation structure C shown in Figure 5 replaces the covering member 40 with a covering member 40' in the opening / closing device installation structure A. It is equipped with a columnar reinforcing member 50 that is in contact with the covering member 40' in the vertical direction, and the opening / closing device 10 is joined to this columnar reinforcing member 50.

[0038] The covering member 40' is formed in a roughly U-shape (or, to put it another way, roughly concave in cross-section) that covers the columnar base member 21 from the front to the back, by a covering piece 41' on the front side that covers the front side of the columnar base member 21, a covering piece 42' on the back side that covers the front side of the columnar base member 21, and a covering piece 43' on the opposite side that covers the front side of the columnar base member 21 (see Figure 5(a)).

[0039] This covering member 40' covers the columnar base member 21 in an elongated manner in the vertical direction. Preferably, the vertical length of this covering member 40' is set to be approximately equal to the vertical length of the columnar base member 21.

[0040] The covering piece 41' on the visible side and the covering piece 43' on the opposite side of the visible side are each provided with a through-hole for inserting the male member 31 and fastening it to the columnar base member 21.

[0041] The male member 31 is inserted through the visible side covering piece 41', the columnar base member 21, and the non-visible side covering piece 43'. The female member 32 is screwed onto and tightened to the tip of the male member 31.

[0042] The columnar reinforcing member 50 is formed in a hollow rectangular column shape using a material that is harder and more rigid than the columnar base member 21 (for example, a hard metal material). The vertical length of this columnar reinforcing member 50 is set to be equal to or greater than the vertical length of the guide rail 12, and preferably to be approximately the same length as the columnar base member 21. This columnar reinforcing member 50 is welded to the surface of the visible side covering piece 42' of the covering member 40'.

[0043] In this opening / closing device installation structure C, the guide rail 12 is aligned and then welded to the visible surface of the columnar reinforcing member 50.

[0044] Furthermore, the means for fixing the columnar reinforcing member 50 to the covering member 40' and the means for fixing the guide rail 12 to the columnar reinforcing member 50 can be other than welding, such as screwing, riveting, or fitting. Furthermore, in the figure, reference numeral 22' indicates a decorative panel that covers the exposed portion of the columnar reinforcing member 50, and it can be omitted.

[0045] Therefore, according to the opening / closing device installation structure C shown in Figure 5, the columnar base member 21 can be reinforced vertically by the covering member 40' and the columnar reinforcing member 50, thereby further improving the durability of the fastening portion of the opening / closing device 10.

[0046] <Switching device installation structure D> The opening / closing device installation structure D shown in Figure 6 is the same as the opening / closing device installation structure C described above, but with the guide rail 12 replaced by a storage case 13b, and the storage section 13 is fixed to the columnar base member 21 via a columnar reinforcing member 50 and a covering member 40'.

[0047] The mounting bracket 13b1 of the storage case 13b is fixed to the visible surface of the columnar reinforcing member 50 by appropriate fixing means (for example, welding, screwing, riveting, fitting, etc.).

[0048] Therefore, according to the opening and closing device installation structure D, it is possible to prevent a decrease in strength and improve durability of the fastening portion of the relatively heavy storage section 13.

[0049] <Opening / closing device installation structure E> In the opening / closing device installation structure E shown in Figure 7, the columnar reinforcing member 50 is joined to the covering member 40 via a connecting piece 60, as in the opening / closing device installation structure D described above.

[0050] The joining piece 60 is an angle-shaped member having one piece portion 61 and the other piece portion 62, and has a substantially L-shaped cross-section that is continuous in the vertical direction. The vertical length of this connecting piece 60 is set to be approximately equal to the vertical length of the columnar reinforcing member 50, for example.

[0051] In the opening / closing device installation structure E, the columnar base member 21 is provided with a covering member 40, a male member 31, a female member 32, etc., in the same manner as in the opening / closing device installation structure A, etc.

[0052] The joining piece 60 is joined to the visible side covering piece 41 of the covering member 40 by the male member 31 and the female member 32. Specifically, the male member 31 penetrates the covering member 40 and the columnar base member 21 from the back side of the wall portion 20, and further penetrates one piece 61 of the joining piece 60. The female member 32 is screwed onto and tightened to the tip side of the male member 31.

[0053] A columnar reinforcing member 50 is welded to the other portion 62 of the joining piece 60 in the vertical direction. A guide rail 12 is positioned and welded to the front surface of the columnar reinforcing member 50.

[0054] Therefore, according to the opening / closing device installation structure E shown in Figure 7, the columnar base member 21 can be reinforced with the covering member 40, the female member 32, etc., and consequently, the durability of the fastening portion of the opening / closing device 10 can be effectively improved.

[0055] Furthermore, the means for joining the connecting piece 60 to the columnar reinforcing member 50, and the means for joining the connecting piece 60 to the columnar reinforcing member 50, can be configured in ways other than welding, such as fastening with screws or rivets, or fitting together. Furthermore, as an example other than the illustrated example, it is also possible to provide multiple short connecting pieces 60, which are shorter than the columnar reinforcing member 50, at intervals in the vertical direction, and to connect the columnar reinforcing member 50 to these multiple connecting pieces 60.

[0056] <Switching device installation structure F> The opening / closing device installation structure F shown in Figure 8 is the same as the opening / closing device installation structure E described above, but with the guide rail 12 replaced by a storage case 13b, and the storage section 13 is fixed to the columnar base member 21 via a columnar reinforcing member 50, a connecting piece 60, and a covering member 40.

[0057] The mounting bracket 13b1 of the storage case 13b is fixed to the columnar reinforcing member 50, which is integral with the covering member 40, by a suitable fastening means (for example, welding, screwing, riveting, fitting, etc.) via a connecting piece 60.

[0058] Therefore, the opening and closing device installation structure F prevents a decrease in strength at the fastening portion of the relatively heavy storage section 13, thereby improving durability.

[0059] <Variation> According to the above embodiment, as a preferred example, three sides of the columnar base member 21 are covered with the covering member 40 (or 40'), but the covering member 40 can be configured to partially or completely cover at least the surface of the columnar base member 21 on the visible side. In other words, other examples of this covering member 40 include covering only the visible surface of the columnar base member 21, covering only two surfaces including the visible surface of the columnar base member 21, and covering all four surfaces of the columnar base member 21. Furthermore, another example of the covering member 40 is that it can cover only a portion of the surface on the visible side of the columnar base member 21 through which the male member 31 penetrates.

[0060] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without altering the essence of the invention.
