DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the term "finding direction" refers to the width direction of the frame 10 (the left-right direction in FIG. 1). Also, the term "prospect direction" refers to the direction of the frame thickness (the left-right direction in FIG. 6) that is approximately perpendicular to the "finding direction". Moreover, the "opening width direction" refers to the lateral width direction of the opening 10a that is opened and closed by the opening / closing body 15, and in this embodiment, is the same direction as the "finding direction." Moreover, the term “inside the frame” refers to the inside of the frame body 10 , and the term “outside the frame” refers to the outside of the frame body 10 . In addition, the "frame thickness direction" means the thickness direction of the frame body 10, which is the same direction as the projection direction in this embodiment.

[0009] <First embodiment> FIG. 1 shows an example of a fitting device 1 to which a fitting frame connecting structure A according to the present invention is applied. The fitting device 1 is a door device including a rectangular frame body 10 and an opening / closing body 15 that rotates within the frame body 10 to open and close. This fitting device 1 connects a frame 10 to the surrounding building material 20 by a fitting frame connecting structure A.

[0010] The frame body 10 is configured as a rectangular frame having an opening 10a (see Figure 2) in the center, and consists of left and right side frame members 11, 12, an upper frame member 13 connected between the upper ends of these side frame members 11, 12, and a lower frame member 14 (sometimes called a door frame) connected between the lower ends of the side frame members 11, 12.

[0011] The side frame members 11, 12, the upper frame member 13 and the lower frame member 14 are formed from metal materials (e.g., iron, stainless steel, aluminum alloy, etc.) that have excellent strength and corrosion resistance, and are welded together in advance at a factory or the like to form the rectangular frame body 10.

[0012] The side frame member 11 has two inward pieces 11a, 11a facing inward from both sides in the frame thickness direction on the outer side of the frame, and is formed in a generally C-shaped cross section with an opening between these inward pieces 11a, 11a (see FIG. 3). The generally C-shaped cross section of the side frame member 11 continues in an elongated shape in the vertical direction. The side frame member 12 is configured symmetrically to the side frame member 11, and like the side frame member 11, has two inward pieces 12a, 12a. The upper frame member 13 is a member having the same cross-sectional shape as the side frame members 11 and is used horizontally, with an opening between the two inward pieces 13a, 13a.

[0013] An opening / closing body 15 is attached inside the frame body 10 so as to be openable and closable (see FIG. 1). According to the illustrated example, the opening / closing body 15 is a door that rotates with its tail portion pivotally supported on one of the side frame members 12. Reference numeral 16 in the drawing denotes a hinge that supports the opening / closing body 15 rotatably.

[0014] The building frame connecting structure A comprises a foundation member 30 fixed to the frame 10, and a connecting member 40 that connects this foundation member 30 to the building material 20 (see FIG. 3).

[0015] The foundation member 30 is a roughly rectangular plate-shaped member extending at an angle to the projection direction so as to span between the two inward pieces 11a, 11a (12a, 12a or 13a, 13a) of each side frame member 11, 12 or the upper frame member 13. For example, as shown in FIG. 6, in each of the vertical side frame members 11 (or 12), the base member 30 is inclined so that one end side in the longitudinal direction is located lower than the other end side. The base member 30 is made of a metal material (such as iron, stainless steel, or aluminum alloy) that is strong and resistant to corrosion.

[0016] Each base member 30 is provided with an inclined long hole 31 inclined with respect to the projection direction (see FIG. 6). This inclined long hole 31 is located between both inward pieces 11a, 11a (12a, 12a or 13a, 13a) of each side frame member 11, 12 or upper frame member 13. The inclination angle α of this inclined long hole 31 is about 30 degrees with respect to the front direction (the left-right direction in FIG. 7).

[0017] With respect to two foundation members 30, 30 adjacent to each other in the circumferential direction of the frame body 10, the inclined long hole 31 of one foundation member 30 and the inclined long hole 31 of the other foundation member 30 are inclined in opposite directions to each other (see FIG. 6).

[0018] One end side and the other end side of the base member 30 are fixed integrally to the inner surface (rear surface) of the inward piece 11a, 12a or 13a, respectively. This fixing means may be welding, but it is also possible to use screws, rivets, etc.

[0019] The connecting member 40 crosses and overlaps the back side of the base member 30. The position of the connecting member 40 relative to the base member 30 can be adjusted in an oblique direction along the inclined elongated hole 31. The connecting member 40 has portions (bent pieces 41b, 41b) on one side and the other side in the intersecting direction (vertical direction according to FIG. 7) with respect to the foundation member 30 bent and joined to the building material 20. The amount of bending of the one side and the other side is appropriately adjusted according to the distance between the frame 10 and the building material 20, etc.

[0020] More specifically, the connecting member 40 is formed from a hard metal material and integrally has a main body portion 41 extending circumferentially around the frame body 10 intersecting the foundation member 30, and connecting portions 42, 42 which are connected to the building material 20 at one end and the other end of the main body portion 41.

[0021] The main body 41 is a long, generally plate-shaped member, and has a base piece 41a located at the center in the longitudinal direction, and bent piece portions 41b, 41b located on both sides of the base piece 41a.

[0022] The base piece portion 41a is formed in a flat plate shape overlapping in a cross shape on the back surface of the foundation member 30. A fastening receiving portion 41a1 (see FIG. 10) for fastening the fastener 50 is provided at the center side of the base piece portion 41a. Moreover, in the main body portion 41, folded portions 41a2, 41a2 that partially reduce bending strength are provided on both sides of the base piece portion 41a.

[0023] The fastener 50 is a shaft-shaped member (for example, a bolt or a screw) having a male threaded portion at the tip end and a head portion 51 at the rear end that can be rotated from one side in the projection direction. The head 51 of this fastener 50 is formed in a hexagonal column shape, and a cross hole for a screwdriver or a hexagonal hole for a hexagonal wrench is provided on an end face thereof as required. The tip side of the fastener 50 is inserted into the obliquely elongated hole 31 of the base member 30, and is screwed into the fastening portion 41a1 of the connecting member 40 and tightened.

[0024] The fastening portion 41a1 is a female screw hole into which the male screw portion of the fastener 50 can be screwed (see Figs. 8 to 10). The fastening portion 41a1 may be formed by providing a through hole of the main body 41 with a burring process and a female screw portion, or by fixing a weld nut to the back side of the through hole of the fastener 50.

[0025] The bent piece portion 41b is a plate-like portion that is bent from the base piece portion 41a toward the building material 20 at the bent portion 41a2.

[0026] The folding portion 41a2 is located at the boundary between the base piece portion 41a and the bent piece portion 41b, and enables the bent piece portion 41b to be bent relative to the main body portion 41. The folded portion 41a2 in the illustrated example has a through hole at the boundary, which makes it easy to fold the bent piece portion 41b relative to the main body portion 41.

[0027] In addition, the folding portion 41a2 may have a configuration in which the bending strength is partially reduced, i.e., the bending strength is reduced compared to the surrounding portions of the folding portion 41a2. Other examples of the folding portion 41a2 include a configuration in which a groove is provided at the boundary, a configuration in which notches are provided on both ends of the boundary, and a configuration in which the thickness of the boundary is reduced compared to other portions.

[0028] The connecting portion 42 is formed in a flat plate shape rising toward the wall side (the building material 20 side) at the tip side of the bent piece portion 41b. The connecting portion 42 is provided with a through hole 42a for inserting the fastener 61 therethrough. As the bent piece 41b is bent towards the building material 20, the joint portion 42 approaches the building material 20 and is joined to the connected member 21 fixed to the building material 20 by being overlapped thereon.

[0029] The building material 20 surrounds the periphery of the frame 10 and is fixed to the framework on which the fitting device 1 is to be installed. The building material 20 is a long member made of hard metal, and is formed from a long material having, for example, a channel steel shape, an angle shape, a rectangular column shape, or the like. A connected member 21 for connecting a joint portion 42 of a connecting member 40 is provided on the end face of this building material 20 on the inside of the frame.

[0030] The connected member 21 is a member that is continuous along the longitudinal direction of the building material 20 (the vertical direction in FIG. 8), and in the illustrated example, is formed in an L-shaped angle shape and is fixed to the end face of the building material 20 on the frame 10 side by fasteners 22 (for example, bolts, screws, rivets, etc.). This fixing means may be welding or another form.

[0031] The connected member 21 has a fastening piece 21a that protrudes from an end face of the building material 20 toward the frame body 10 (see FIG. 3). The fastening piece 21a is overlapped with the coupling portion 42 of the connecting member 40 and is fastened by a fastener 61.

[0032] The fastener 61 is a screw having a drill bit on the tip side, and may be called a tapping screw with a drill or the like. The fastener 61 is inserted into the through hole 42a (see FIG. 8) of the coupling portion 42, and is screwed onto the fastening piece portion 21a of the connected member 21 and tightened.

[0033] Between the frame 10 and the building material 20 configured as described above, an operating space S is provided for rotating the head 51 of the fastener 50 with a tool T1 (see FIG. 3).

[0034] Tool T1 is a tool for rotating head 51 of fastener 50 to one side in the projection direction (indoor or outdoor side). For example, if head 51 of fastener 50 is a hexagonal head, tool T1 may be a spanner or box wrench that fits into head 51 of fastener 50. Also, if head 51 of fastener 50 has a hexagonal hole, tool T1 may be a hexagonal wrench that fits into the hexagonal hole.

[0035] 3, reference numeral 23 denotes a wall portion that covers the building material 20 and the operation space S from both sides in the prospective direction. This wall portion 23 is made of, for example, gypsum board, plywood, other panel materials, decorative boards, or the like.

[0036] In addition, in FIG. 8, reference symbol T2 denotes a bending tool for bending the bent pieces 41b, 41b on both sides of the connecting member 40 toward the building material 20. This bending tool T2 is an L-shaped shaft member, and has at one end thereof a fitting portion that fits in a concave-convex manner with the bending piece portion 41b of the connecting member 40, and the other end thereof serves as a rotation operation portion for rotation operation. For example, the bending tool described in Patent Document 2 can be used as this bending tool T2.

[0037] <Installation procedure> Next, a procedure for installing the fitting device 1 in an opening in the framework of a building or the like will be described in detail. The building material 20 is immovably fixed to a building frame or the like on which the fitting device 1 is to be installed by, for example, welding, screwing, riveting, or the like. A connected member 21 is fastened to this building material 20 by a fastener 22 (see FIG. 3).

[0038] The foundation member 30 is fixed integrally to the side frame members 11, 12 and the upper frame member 13 of the frame body 10 before the frame body 10 is inserted inside the left, right and upper building materials 20 (for example, during the manufacturing stage in a factory or when the frame body 10 is delivered to the site, etc.).

[0039] Thereafter, the connecting member 40 is joined to the base member 30 . In more detail, the connecting member 40 is crossed over the base member 30 on the back side (see FIG. 4(a)), the fastener 50 is inserted into the inclined long hole 31 of the base member 30, the male threaded portion of the fastener 50 is screwed into the fastened portion 41a1 of the connecting member 40, and the fastener 50 is rotated with the tool T1 to temporarily tighten (see FIG. 3). Before installing the frame body 10 inside the rectangular building material 20, the fasteners 50 may be temporarily fastened with a screwdriver or the like.

[0040] Next, using a bending tool T2, the bent pieces 41b, 41b on both sides of the connecting member 40 are each bent toward the building material 20, and the joining portion 42 at the tip side of each bent piece 41b is overlapped with the fastening piece portion 21a of the connected member 21 (see Figures 4(b), 8 and 9).

[0041] Then, this overlapping portion is joined by a fastener 61 (see FIG. 5(c) and FIG. 9). The fastener 61 is formed by drilling a hole in the fastening piece 21a with a drill bit on the tip side, and then screwing the fastener 61 into the hole and tightening it. Thereafter, the temporarily fastened fastener 50 is fully fastened by the tool T1.

[0042] The above-mentioned work is carried out for each of the multiple door and window frame body connecting structures A (see FIG. 2) provided around the frame body 10. Then, by these works, the frame body 10 is fixed immovably to the building material 20.

[0043] Therefore, according to the above-described configuration of the door frame body connecting structure A, the fastening device 50 is inserted into the inclined long hole 31 and this fastening device 50 is fastened to the connecting member 40, thereby preventing the frame body 10 from shifting in the expected direction along the horizontal direction or rattling during or after the above-described installation work. In other words, if the inclined long hole 31 were a horizontal long hole with no inclination, there would be a risk that the frame body 10 would shift horizontally or wobble during the installation work described above, but according to the present invention, this can be prevented. In particular, in a preferred example of this embodiment, for the door frame body connecting structures A, A adjacent to each other in the circumferential direction of the frame body 10, the inclination direction of one of the inclined long holes 31 is reversed to the inclination direction of the other inclined long hole 31 (see Figure 6), thereby effectively suppressing the above-mentioned deviation in the expected direction and rattling.

[0044] Furthermore, if the fastener 50 is loosened during or after the installation work, the position of the frame body 10 can be adjusted in the prospective direction by the amount of play between the fastener 50 and the oblique elongated hole 31.

[0045] <Second embodiment> Next, another example of the door frame body connecting structure according to the present invention will be described. In addition, since the embodiment described below is a modified version of the above-mentioned door frame body connecting structure A, the modified parts will mainly be described in detail, and parts that function in a similar manner will be given the same symbols and redundant explanations will be omitted.

[0046] The door frame body connecting structure B shown in Fig. 11 is door frame body connecting structure A. By replacing the connecting member 40 with a connecting member 40' and replacing the connected member 21 with a connected member 21', the foundation member 30 is integrated with a joint portion 42' that protrudes toward the building material 20 side (wall side), and the building material 20 is integrated with a fastening piece portion 21a' so as to be located on the expected direction side of the joint portion 42'. In addition, the fitting frame connecting structure B joins the joint portion 42' and the fastening piece portion 21a' with an adjustment screw 81 that can be rotated.

[0047] The connecting member 40' has the connecting portion 42 of the connecting member 40 replaced with a connecting portion 42'. The connecting portion 42' is a plate-like portion that protrudes toward the building material 20 and extends in the vertical direction, and an adjustment screw 81 is inserted through the connecting portion 42' so as to be freely rotatable.

[0048] The adjustment screw 81 has a male thread at the tip end and a head at the rear end, the head being provided with a cross recess or a hexagonal recess so as to be rotatable. The male thread of the adjustment screw 81 passes through the coupling part 42', and a retaining ring 82 is attached to the passing part. Therefore, the adjustment screw 81 is rotatable relative to the coupling part 42', and is held by the head and the retaining ring 82 so as not to move in either direction.

[0049] The connected member 21' is obtained by replacing the fastening piece portion 21a of the connected member 21 with a fastening piece portion 21a'. The fastening piece 21a' is formed in a plate shape that protrudes toward the foundation member 30 (the door / window fixture side) and is generally parallel to the coupling part 42' in the vertical direction. The fastening piece 21a' is provided with a female screw part 21a1' for passing the adjustment screw 81 through and screwing into it.

[0050] According to the illustrated example, the female screw portion 21a1' is composed of a through hole and a weld nut concentric with the through hole. As another example of the fastening piece portion 21a', a female screw hole can be provided directly in a plate-like portion.

[0051] An adjustment screw 81 is screwed into the female screw portion 21a1'. A fixing nut 83 is screwed into the tip end of the adjustment screw 81 and tightened.

[0052] Therefore, according to the fitting frame connecting structure B shown in Fig. 11, even after the connecting member 40' is fixed to the connected member 21', if the fixing nut 83 is loosened and the adjustment screw 81 is rotated with a specified tool T3 such as a screwdriver or hexagonal wrench, the frame 10 can be moved in the projection direction according to the amount of rotation. In other words, the position of the frame 10 in the projection direction can be easily adjusted. The position adjustment by the above work is performed for each of the upper and lower joints 42', 42'. After these position adjustments, the fixing nuts 83 are tightened to fix the frame 10.

[0053] <Modification> According to the above embodiment, the foundation member 30 is fixed to the frame body 10 on the fitting side, and this foundation member 30 is connected to the building material 20 on the wall side by the connecting member 40. However, as another example, it is also possible to fix the foundation member 30 to the building material 20 on the wall side, and connect this foundation member 30 to the frame body 10 on the fitting side by the connecting member 40.

[0054] According to the above embodiment, the base member 30 is formed in an elongated shape inclined along the longitudinal direction of the inclined long hole 31, but as another example, it is also possible to have an aspect in which only the inclined long hole 31 is inclined without inclining the base member 30.

[0055] In the example shown in FIG. 11, an adjustment screw 81 is provided on the foundation member 30 side, and a female screw portion 21a1' is provided on the building material 20 side. However, as another example, it is also possible to provide the female screw portion on the foundation member 30 side, and an adjustment screw that screws into this female screw portion on the building material 20 side, thereby making it possible to have the opposite configuration.

[0056] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without departing from the gist of the present invention.
