Description

[Technical field]

[0001] The present invention relates to a hinge mounting structure and method. [Background technology]

[0002] A hinge generally consists of a first member and a second member (these members are called, for example, blades) that are connected to each other so that they can rotate freely. The first member is fixed to an opening / closing body such as a door body, while the second member is fixed to the main body, so that the opening / closing body can be attached to the main body so that it can be opened and closed.

[0003] There are several types of mounting methods for the hinge to the frame, and for example, there is one in which the second member, a blade, is fixed to the surface of the frame, and another type in which the second member, a blade, is inserted into a hole formed in the frame and fixed (see Patent Document 1). In the latter type, when the opening through which the door body opens and closes is formed from a hollow metal frame, a notch is typically formed in a predetermined position of the vertical frame on the end side of the frame, and the blade is inserted into the notch and fixed inside the frame.

[0004] In the latter type, when the door body is attached to an opening connecting the indoors and the outdoors and is exposed to rain and wind in a fully closed position, water may seep into the vertical frame through the gap (clearance) between the notch formed in the vertical frame and the panel inserted into said notch, and then pass through the hollow part of the vertical frame and further into the interior of the building.

[0005] One method of waterproofing the hinge mounting structure is to fill the inside of the vertical frame with sealant. However, the space available for filling the sealant is narrow, and it is difficult to visually check the state of the sealant filling during work, making the work difficult and the waterproofing effect insufficient. [Patent Document 1] JP 5-179857 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a hinge mounting structure and method which provides a sufficient waterproofing effect and is easy to work with in a hinge of the type in which the hinge blades are inserted into a frame body. [Means for solving the problem]

[0007] The technical means adopted in the present invention are: In a hinge mounting structure in which the hinge blades are inserted into insertion holes formed in a frame body and fixed inside the frame body, A cover is provided inside the frame body so as to form an enclosed space surrounding an insertion portion of the blade located inside the frame body, The enclosed space is filled with a filler, and the filler closes a gap between the surface of the blade and the insertion hole from inside the frame body. This is a hinge mounting structure. The enclosed space is connected to the gap, but even if water seeps in through the gap, the water remains within the enclosed space filled with the filler, preventing water from seeping into the frame body as much as possible.

[0008] In one embodiment, the filling material is a foamed material, and an injection portion for injecting the foamed material into the enclosed space is formed in the portion that forms the enclosed space, and the enclosed space is filled with the foamed filling material. In one embodiment, the injection portion is a notch or a hole formed in the cover.

[0009] In one embodiment, the cover has at least an upper surface facing above the upper surface of the insertion site, a lower surface facing the lower surface of the insertion site, and a bottom surface facing the tip surface of the insertion site, The cover, together with a portion of the frame body and the fixed member of the insertion site located within the frame body, forms the enclosed space.

[0010] In one embodiment, the insertion hole is formed on a front surface of the frame, The fixed member fixed to an inner surface of a projection portion extending from the projection surface forms one side surface of the enclosed space, An outer projected edge extends from the projected surface opposite the projected portion, The cover has a side formed on the bottom side, and the tip of the side and the tip of the outer projected edge abut each other, forming the other side portion of the enclosed space from the side and the outer projected edge of the cover.

[0011] The technical means adopted in the present invention are: A method for mounting a hinge in which the hinge blades are inserted into insertion holes formed in a frame and fixed inside the frame, providing a cover inside the frame so as to form an enclosed space surrounding an insertion portion of the blade to be inserted into the frame; a step of inserting a hinge blade through the insertion hole and positioning an insertion portion in the enclosed space; filling the enclosed space with a filler; The hinge mounting method comprises:

[0012] In one embodiment, the filler is a foam material; An injection part for injecting a foaming material into the enclosed space is formed in a portion that forms the enclosed space, By injecting the foaming material from the injection portion, the injected foaming material foams and seals the enclosed space. In one embodiment, the injection portion is a notch or a hole formed in the cover.

[0013] In one embodiment, the cover has at least an upper surface facing above the upper surface of the insertion site, a lower surface facing the lower surface of the insertion site, and a bottom surface facing the tip surface of the insertion site, The cover, together with a portion of the frame body and the fixed member of the insertion site located within the frame body, forms the enclosed space. Effect of the Invention

[0014] In the present invention, a cover is provided inside the frame body so as to form an enclosed space surrounding the insertion portion of the blade located inside the frame body, and a filler material fills the enclosed space to seal the gap between the surface portion of the blade and the insertion hole from inside the frame body, thereby preventing water from entering the inside of the frame body as much as possible. In the present invention, a cover is provided inside the frame body so as to form an enclosed space surrounding the insertion site of the hinge blade to be inserted into the frame body, so that a water-stopping structure can be formed simply by injecting filler during the hinge installation process, resulting in good workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] 1 is a front view of a door device in a fully closed position as seen from the outdoor side, and the door device comprises a vertical rectangular door body 1 and a door frame consisting of an upper frame 2, a trailing edge vertical frame 3, a front edge vertical frame 4, and a lower frame 5. The door device is a hinged door, and the trailing edge side portion of the door body 1 is rotatably attached to the trailing edge vertical frame 3 by a hinge 6. The door body 1 in this embodiment is a large door body, but the size of the door body 1 is not limited.

[0017] The hinge 6 is composed of a first slat 60 fixed to the trailing edge portion of the outdoor side surface portion 1' of the door body 1, a second slat 61 inserted into the trailing edge vertical frame 3 and fixed therein, and a shaft portion 62 to which the base ends of the first slat 60 and the second slat 61 are rotatably attached. In the illustrated embodiment, three hinges 6 are provided along the height of the door body 1, but the number of hinges 6 is not limited. In this embodiment, a support member 7 extending in the height direction along the trailing edge vertical frame 3 is provided inside the trailing edge vertical frame 3, and the second slat 61 of the hinge 6 is fixed to the support member 7 inside the trailing edge vertical frame 3.

[0018] The trailing edge vertical frame 3 is a long member extending in the opening height direction, and as shown in Fig. 5, has a narrow first visible surface 30 facing the outside and a wide second visible surface 31 facing the inside, and the visible portion of the trailing edge vertical frame 3 consists of a first visible surface 32 on the first visible surface 30 side, a second visible surface 33 on the second visible surface 31 side, and an intermediate visible surface 34 forming a step portion between the first visible surface 32 and the second visible surface 33. The first visible surface 30 is formed with a first outer visible edge 35 extending opposite the first visible surface 32, and the second visible surface 31 is formed with a second outer visible edge 36 extending opposite the second visible surface 33.

[0019] The first visible surface 30 of the end-of-door vertical frame 3 has an insertion hole 300 into which the second blade 61 of the hinge 6 is inserted at a position corresponding to the mounting position (upper end portion, lower end portion, midway portion) of the hinge 6. The insertion hole 300 has a shape corresponding to the cross-sectional shape of the second blade 61 of the hinge 6, and in this embodiment, the cross-sectional shapes of the insertion hole 300 and the second blade 61 are vertically rectangular. The area (height dimension, width dimension) of the insertion hole 300 is slightly larger than the cross-sectional area (longitudinal dimension, transverse dimension) of the second blade 61, and when the second blade 61 is inserted into the insertion hole 300, there is a slight gap (clearance) C between the surface portion of the second blade 61 (four peripheral surfaces consisting of the left side surface portion 610, the right side surface portion 611, the upper end surface 612, and the lower end surface 613) and the edge of the insertion hole 300 (FIG. 7). Incidentally, "left" and "right" refer to "left" and "right" when viewed from the insertion direction of the second leaf 61 of the hinge 6 (the direction of the arrow in FIG. 5).

[0020] When the second leaf 61 of the hinge 6 is inserted into the trailing edge vertical frame 3 through the insertion hole 300 formed in the first visible surface 30, the left side surface 610, the right side surface 611, the upper end surface 612, and the lower end surface 613, excluding their respective base end portions (sides closer to the shaft portion 62), and the tip surface 614, are insertion portions located within the trailing edge vertical frame 3.

[0021] As shown in Fig. 1, the support member 7 is an elongated member extending in the opening height direction, and as shown in Fig. 5, etc., has an L-shaped cross section with a projection portion 70 extending in the projection direction (indoor / outdoor direction) and a projection portion 71 extending in the projection direction. The projection portion 70 of the support member 7 has a projection dimension larger than the first projection surface 32 of the tail-end vertical frame 3, and is fixed (welded) in a state in which the tip of the projection portion 70 is close to or abuts the inner surface of the first projection surface 30 and the first surface 700 on one side of the projection portion 70 is abutted against the inner surface of the first projection surface 32, and the base end side of the projection portion 70 faces the second projection surface 33, and the projection portion 71 extends to the outside of the tail-end vertical frame 3 through the space between the first outer projection edge 35 and the second outer projection edge 36. It should be noted that the dimensions of the projected portion 70 and the visible portion 71 of the support member 7 shown in the figures are merely examples, and for example, the projected dimension of the projected portion 70 of the support member 7 may be smaller than the first projected surface 32 of the trailing edge vertical frame 3, or the visible portion 71 of the support member 7 may have a dimension that fits within the leading edge vertical frame 3. In addition, the shape of the support member 7 shown in the figures is merely an example, and the shape of the support member 7 is not limited to an L-shape in cross section.

[0022] A first belt-like connecting plate 37 and a second belt-like connecting plate 38 are provided on the trailing edge vertical frame 3 so as to extend horizontally and face the projected portion (first projected surface 32, second projected surface 33) of the trailing edge vertical frame 3. Although one first belt-like connecting plate 37 and one second belt-like connecting plate 38 are shown in Fig. 3, a plurality of first belt-like connecting plates 37 and second belt-like connecting plates 38 are provided along the height direction of the trailing edge vertical frame 3.

[0023] The first belt-shaped connecting plate 37 according to this embodiment has bent pieces 370, 371 extending in different directions at the position where the hinge 6 is provided, and the bent piece 371 on the base end side is disposed so that the tip abuts against the second surface 701 of the projection portion 70 of the support member 7 and abuts against the bottom surface 82 (described later) of the cover 8, and the bent piece 370 on the tip side abuts against one surface of the projection portion 71 of the support member 7. At the position where the hinge 6 is not provided, the cover 8 is not provided, and the first belt-shaped connecting plate 37 does not have the bent piece 371 at one end, and the first belt-shaped connecting plate 37 extends to overlap the first outer projection edge 35 at one end and is connected to the first outer projection edge 35.

[0024] The second belt-shaped connecting plate 38 has a base end connected to the second outer projected edge 36, and a bent piece 380 integrally formed at the tip abuts against the other surface of the visible portion 71 of the support member 7. If the visible portion 71 of the support member 7 is small, one belt-shaped connecting plate may be used. In one embodiment, the trailing edge vertical frame 3 is fixed (welded) to the frame via the support member 7. The first belt-shaped connecting plate 37 and the second belt-shaped connecting plate 38 may be used auxiliary to fix the trailing edge vertical frame 3 to the frame.

[0025] The thickness of the projection portion 70 and the projection portion 71 of the support member 7 is thicker than the plate material forming the trailing edge vertical frame 3, and has the strength to support the weight of the large door body 1. With the first surface 700 on one side of the projection portion 70 in contact with the inner surface of the first projection surface 32, the second surface 701 on the other side of the projection portion 70 is located in such a position that the surface portion (left side surface portion 610) of the second blade 61 of the hinge 6 inserted from the insertion hole 300 of the trailing edge vertical frame 3 comes into sliding contact with the projection portion 70 of the support member 7, and the second blade 61 of the hinge 6 inserted inside the trailing edge vertical frame 3 is brought into contact with the projection portion 70 of the support member 7 and fixed with the screws 10 (8 pieces).

[0026] The area (height dimension, width dimension) of the insertion hole 300 is slightly larger than the cross-sectional area (longitudinal dimension, transverse dimension) of the second slat 61, and when the second slat 61 is inserted into the insertion hole 300, a slight gap C (see FIG. 7) exists between the surface portion of the second slat 61 (four peripheral surfaces consisting of a left side surface portion 610, a right side surface portion 611, an upper end surface 612, and a lower end surface 613) and the edge portion of the insertion hole 300. In this embodiment, in the mounting structure of the hinge 6, the enclosed space S around the insertion portion of the second slat 61 of the hinge 6 inserted into the trailing edge vertical frame 3 is blocked with a filler 9, thereby blocking the gap C from the inside of the trailing edge vertical frame 3. The filler 9 is preferably a foamable filler, and in this embodiment, urethane foam is used as the filler 9.

[0027] In this embodiment, a cover 8 is provided located inside the insertion hole 300 into which the second flap 61 of the hinge 6 of the trailing edge vertical frame 3 is inserted, and the cover 8 cooperates with a portion of the trailing edge vertical frame 3 (first visible surface 30, first outer projected edge 35) and a portion of the support member 7 (projected portion 70) to form an enclosed space S that surrounds the insertion portion of the second flap 61 of the hinge 6 inserted into the trailing edge vertical frame 3, and this enclosed space S is filled with urethane foam.

[0028] As shown in FIG. 8, the cover 8 according to this embodiment is made up of an upper surface 80 and a lower surface 81 that are rectangular in plan view, a bottom surface 82 that extends in the height direction so as to connect one end (i.e., one short side) of the upper surface 80 and the lower surface 81 in the longitudinal direction, and a side surface 83 that extends in the height direction so as to connect the bottom side parts of one long side of the upper surface 80 and the lower surface 81, and the end of the bottom surface 82 and the end of the side surface 83 abut against each other to form a corner. Two notches 84 are formed at the tip side of the side surface 83, one above the other. As will be described later, the notches 84 form an injection part 84' for the filler, and the part and the number of notches 84 are not limited, and it is sufficient that one or more notches 84 are formed on any surface of the cover 8.

[0029] The cover 8 is attached to the inside of the trailing edge side vertical frame 3 with its top surface 80 and bottom surface 81 horizontal and its bottom surface 82 and side surfaces 83 vertical, with the bottom surface 82 being the visible surface and the side surfaces 83 being the visible surfaces. The cover 8 is fixed to the trailing edge side vertical frame 3, for example, by welding a portion of the trailing edge side vertical frame 3 or a contact portion with the support member 7. The side of the cover 8 farther from the bottom surface 82 is defined as the front.

[0030] 2 to 4 and 6, the height dimension of cover 8 is greater than the height dimension of insertion hole 300, with upper surface 80 positioned above the upper edge of insertion hole 300 and lower surface 81 positioned below the lower edge of insertion hole 300. The front end portion (the other short side) of upper surface 80 is adjacent to or abuts against the inner surface of first visible surface 30, and the front end portion (the other short side) of lower surface 81 is adjacent to or abuts against the inner surface of first visible surface 30.

[0031] The width dimension of the cover 8 (the width dimension of the upper surface 80, the lower surface 81, and the bottom surface 82) is approximately the same as the dimension between the second surface 701 of the projection portion 70 of the support member 7 and the inner surface of the first outer projection edge 35 of the trailing edge vertical frame 3, and the cover 8 is positioned in a portion of the internal space of the trailing edge vertical frame 3 that corresponds to the insertion hole 300 and includes the space between the second surface 701 of the projection portion 70 of the support member 70 and the inner surface of the first outer projection edge 35.

[0032] The projected dimensions of cover 8 are larger than the projected dimensions of the first outer projected edge 35, one short side of the upper surface 80 of cover 8, one short side of the lower surface 81, and the bottom surface 82 of cover 8 are located closer to the second visible surface 31 than the tip of the first outer projected edge 35, the tip of the side surface 83 of cover 8 abuts the tip of the first outer projected edge 35, and the first outer projected edge 35 and the side surface 83 of cover 8 are integral and form a side portion facing the projected portion 70 of the support member 7.

[0033] In this way, an enclosed space S surrounding the insertion portion of the second flap 61 of the hinge 6 is formed by the inner surface of the first visible surface 30 of the trailing edge vertical frame 3, the inner surface of the first outer projected edge 35, the second surface 701 of the projected portion 70 of the support member 7, and the upper surface 80, lower surface 81, bottom surface 82, and side surface 83 of the cover 8. In other words, the front portion of the enclosed space S is formed by the first visible surface 30, the upper surface portion is formed by the upper surface 80 of the cover 8, the lower surface portion is formed by the lower surface 81 of the cover 8, one side surface portion is formed by the projected portion 70 of the support member 7, the other side surface portion is formed by the first outer projected edge 35 and the side surface 83 of the cover 8, and the rear surface portion is formed by the bottom surface 82 of the cover 8. The surrounding space S communicates with a gap C between the surfaces of the second panel 61 (left side surface 610, right side surface 611, upper end surface 612, lower end surface 613) and the edge of the insertion hole 300.

[0034] When the second leaf 61 of the hinge 6 is inserted through the insertion hole 300 formed in the first visible surface 30 of the trailing edge vertical frame 3, one side portion of the insertion portion (portion 610' of the left side portion 610) abuts against the second surface 701 of the projected portion 70 of the support member 7 and is fixed by the screw 10, the other side portion of the insertion portion (portion 611' of the right side portion 611) faces, at a distance, the side portion consisting of the inner surface of the first outer projected edge 35 and the side surface 83 of the cover 8, the upper end surface of the insertion portion (portion 612' of the upper end surface 612) faces, at a distance, the upper surface 80 of the cover 8, the lower end surface of the insertion portion (portion 613' of the lower end surface 613) faces, at a distance, the lower surface 81 of the cover 8, and the tip surface 614 of the insertion portion faces, at a distance, the bottom surface 82 of the cover 8.

[0035] In the side surface portion formed by the abutment of the tip of the side surface 83 of the cover 8 and the tip of the first outer projected edge 35, a filler injection part 84' is formed by a notch 84 formed in the side surface 83 (see Figs. 3 and 6). By injecting urethane foam into the space using a urethane foam spray 9' from the injection part 84', the space around the insertion part of the second leaf 61 of the hinge 6 is filled and closed by the filler 9 made of urethane foamed in the space, and the gap C is closed from the inside of the trailing edge vertical frame 3 (see Fig. 7). The foamed urethane may enter the gap C. The part where the filler injection part 84' is formed is not limited. For example, a hole formed in the upper surface 80 or the lower surface 81 of the cover 8 may be used as the injection part. Alternatively, a notch formed in a part of the trailing edge vertical frame 3 (for example, the first outer projected edge 35) may be used as the injection part.

[0036] The process for attaching the hinge 6 according to this embodiment is as follows. (A) Inside the trailing edge vertical frame 3, a cover 8 is provided so as to form an enclosed space S surrounding the insertion portion of the second flap 61 of the hinge 6 inserted from the insertion hole 300 of the first visible surface 30 of the trailing edge vertical frame 3. The enclosed space S according to this embodiment is formed by the first visible surface 30 (front surface), the upper surface 80 (upper surface portion) of the cover 8, the lower surface 81 (lower surface portion) of the cover 8, the projection portion 70 (side surface portion) of the support member 7, the first outer projection edge 35 and the side surface 83 (side surface portion) of the cover 8, and the bottom surface 82 (rear surface portion) of the cover 8.

[0037] (a) The second leaf 61 of the hinge 6 is inserted into the insertion hole 300 of the first visible surface 30 of the trailing edge vertical frame 3 and inserted into the interior of the trailing edge vertical frame 3. (c) One side surface portion 610' of the insertion portion of the second flap 61 of the hinge 6 inserted into the inside of the trailing edge vertical frame 3 is abutted against the projected portion 70 of the support member 7 and fixed with the screw 10. The periphery of the insertion portion of the second flap 61 of the hinge 6 is surrounded by an enclosed space S. More specifically, the other side surface portion (portion 611' of the right side surface portion 611) of the insertion portion of the second flap 61 of the hinge 6 faces, at a distance, a side surface portion consisting of the inner surface of the first outer projected edge 35 and the side surface 83 of the cover 8, the upper end surface (portion 612' of the upper end surface 612) of the insertion portion faces, at a distance, the upper end surface (portion 613' of the lower end surface 613) of the insertion portion faces, at a distance, the lower end surface of the insertion portion faces, at a distance, the lower surface 81 of the cover 8, and the tip surface 614 of the insertion portion faces, at a distance, the bottom surface 82 of the cover 8.

[0038] (d) Urethane foam is injected from injection portion 84' formed in the side portion consisting of the inner surface of first outer projected edge 35 and side surface 83 of cover 8. At this time, in order to prevent the urethane foam from spilling out of first visible surface 30 from gap C between the surface portion of second panel 61 and the edge of insertion hole 300, gap C may be blocked with masking tape. (E) The urethane foam injected into the enclosed space S foams, filling the enclosed space S surrounding the insertion portion of the second slat 61 with the urethane foam. The enclosed space S is a relatively narrow space, but the injected urethane foam foams within the enclosed space S, so that the space can be filled satisfactorily with the urethane foam. The urethane foam filling the enclosed space S closes the gap C between the surface of the second slat 61 and the edge of the insertion hole 300 from the inside of the trailing edge vertical frame 3.

[0039] In this embodiment, the cover 8 is attached to a predetermined portion of the trailing edge vertical frame 3 in a factory, the second slat 61 of the hinge 6 is inserted through the insertion hole 300 of the first visible surface 30 of the trailing edge vertical frame 3, and fixed to the projection portion 70 of the support member 7 with the screw 10, and urethane foam is injected through the injection portion 84' to obtain a waterproof structure. In the method for mounting the hinge 6 according to this embodiment, the waterproof structure can be formed simply by injecting urethane foam during the process of mounting the hinge 6, and the workability is good. In addition, the urethane foam filled to surround the insertion portion of the second slat 61 of the hinge 6 is soft, so it does not interfere with the replacement of the hinge 6.
