Description

[Technical Field]

[0001] The present invention relates to a fitting having a door body that is rotatably attached via hinges to a frame that is attached to a building. [Background technology]

[0002] Conventionally, fittings have been known in which a door body, placed inside a frame body provided in an opening of a building, is connected to the frame body by a hinge so that it can be opened and closed (see, for example, Patent Document 1). In this fitting, a frame-side slat that forms the hinge and has an axis that protrudes upward is attached directly to the visible surface of the vertical frame that forms the frame body.

[0003] [Patent Document 1] JP 2018-127861 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional building materials, the frame-side slats, which form the hinges and have an axis that protrudes upward, are attached directly to the visible surface of the vertical frame, so when a large external force acts on the door body when it is closed or open, the frame-side slats that support the door body may press the visible surface of the vertical frame in an out-of-plane direction, or a moment of rotation in an in-plane direction may act, which could cause the vertical frame to deform.

[0005] The present invention was made in consideration of such problems, and its purpose is to provide a fitting in which the vertical frame is less likely to deform even when an external force is applied from the door body via the hinge. [Means for solving the problem]

[0006] The main invention for achieving this objective is a fitting comprising a frame body to be attached to a building, and a door body that is rotatably attached to a vertical frame of the frame body via a hinge, wherein the hinge comprises a frame side member having a frame side panel portion fixed to a projected surface portion that forms a projected surface in the vertical frame, and an axle portion that is provided at the outside end of the frame side panel portion and has a rotation axis that extends upward, and a door body side member that is fixed to the door body and engages with the rotation axis to rotate, wherein the frame side panel portion is fixed to the vertical frame by clamping the projected surface portion together with a metal fixing plate that is fixed to the projected surface portion by a plurality of fixing devices that are arranged at intervals in the vertical direction, and the position of at least one of the plurality of fixing devices is at the same height as the tip of the axle portion or higher than the tip of the axle portion. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a fitting in which the vertical frame is less likely to deform even when an external force is applied from the door body via the hinge. [Brief explanation of the drawings]

[0009] Hereinafter, a fitting according to one embodiment of the present invention will be described with reference to the drawings. As an example of a fitting 1 according to this embodiment, as shown in Figure 1, we will explain a fitting 1 having a frame body 2 fixed to the building's framework to form an opening 1a, and a door 3 as a door body attached to the frame body 2 via hinges 4 so that it can be opened and closed freely.

[0010] As shown in Figure 1, the fitting 1 of this embodiment has a door 3 attached to the left vertical frame 20 constituting the frame body 2 via a hinge 4 so that it can be opened and closed freely. In the following explanation, when the fitting 1 attached to a building or the like is viewed from the inside of a room, the up-down direction is referred to as the up-down direction, the left-right direction is referred to as the left-right direction, and the depth direction, which is the direction from inside to outside, is referred to as the front direction. In addition, in the front direction, the side to which the door 3 moves when opening is referred to as the outside, and the opposite side, where a door stop is provided, is referred to as the inside. Furthermore, the side of the opening 1a on the inside of the frame body 2 is referred to as the inner circumferential side, and the outside of the frame body 2 opposite the opening 1a is referred to as the outer circumferential side.

[0011] As shown in Fig. 2, the vertical frame 20 is a composite frame material formed by engaging and joining a metal vertical frame 21 made of aluminum and placed on the exterior side in the projection direction with a resin vertical frame 22 made of synthetic resin and placed on the interior side in the projection direction. Both the metal vertical frame 21 and the resin vertical frame 22 are extruded shapes whose extrusion direction is in the up-down direction (longitudinal direction).

[0012] The metal vertical frame 21 has a substantially rectangular cross section that is long in the projection direction and has a projection surface 21b that penetrates in the vertical direction, and the door 3 forms a hollow portion 21a and is attached so as to be able to be opened and closed via hinges 4 to a projection surface portion 21c that forms the projection surface 21b on the inner periphery side that is the opening 1a formed by the frame body 2. The door 3 is attached to the metal vertical frame 21 by three hinges 4 that are appropriately spaced apart in the vertical direction. The following description will use the topmost hinge 4 as an example, but the other hinges 4 are similar.

[0013] As shown in Figure 3, each hinge 4 has a frame side member 40 that has a vertically extending pivot shaft 40a and is attached to the vertical metal frame 21, and a door side member 41 that is attached to the door 3. The frame side member 40 has a flat frame side plate portion 40b that faces and abuts against the visible surface 21b of the visible surface portion 21c, and a shaft portion 40c that is provided at the outside edge of the frame side plate portion 40b and has the pivot shaft 40a that extends upward. The frame side plate portion 40b has a countersunk insertion hole 40e through which a countersunk screw 6 for fixing to the vertical metal frame 21 is inserted.

[0014] The shaft portion 40c has a cylindrical shaft base 40d connected to the frame side plate portion 40b, and a rotating shaft 40a protruding upward from the shaft base 40d. The diameter of the rotating shaft 40a is smaller than the diameter of the shaft base 40d, and the rotating shaft 40a is formed coaxially with the shaft base 40d.

[0015] The door side member 41 has a flat door side plate portion 41a that faces and abuts against the side surface 3a of the door 3, and a bearing portion 41c that is provided at the outside edge of the door side plate portion 41a and has a bearing hole 41b through which the rotation shaft 40a of the frame side member 40 is inserted. The door side plate portion 41a is provided with an insertion hole 41d through which a screw for fixing to the door 3 is inserted.

[0016] The bearing portion 41c is cylindrical with a closed upper end and connected to the door side plate portion 41a, and the bearing hole 41b is recessed upward with an open lower end, with its inner diameter slightly larger than the diameter of the rotating shaft 40a. The depth of the bearing hole 41b is deeper than the amount of upward protrusion of the rotating shaft 40a from the shaft base 40d.

[0017] The frame-side member 40 and the door-side member 41 are arranged such that the rotation shaft 40a of the frame-side member 40 is inserted into the bearing hole 41b of the door-side member 41, and the bearing portion 41c is placed on the shaft base portion 40d. At this time, the upper end 40g of the rotation shaft 40a is not in contact with the bearing portion 41c.

[0018] The door 3 to which the door side member 41 is attached is rotatably supported by the vertical frame 20 via the frame side member 40 by the door side member 41 rotating around the rotation axis 40a.

[0019] The door side panel portion 41a is directly screwed to the side surface 3a of the door 3, and the frame side panel portion 40b is provided in the hollow portion 21a and is fixed to a fixing plate 5 which is fixed to the visible surface portion 21c with a screw 7 as a fixing device, by a countersunk screw 6 inserted into the insertion hole 21d of the visible surface portion 21c.

[0020] The fixing plate 5 is, for example, a rectangular flat plate made of steel (hot-dip galvanized steel plate), and is arranged so that its longitudinal direction coincides with the longitudinal direction of the vertical metal frame 21. The fixing plate 5 has two screw holes 5a at both ends in the longitudinal direction, into which screws 7 are respectively screwed, and four screw holes 5b in the center in the longitudinal direction, into which countersunk screws 6 are screwed. The fixing plate 5 has a shape that is line-symmetrical with respect to a straight line that passes through the center in the longitudinal direction.

[0021] The fixing plate 5 is in contact with the visible surface portion 21c in the hollow portion 21a and is attached by screwing screws 7 inserted into two insertion holes 21d provided in the visible surface portion 21c. At this time, the four screw holes 5b provided in the fixing plate 5 and the four insertion holes 21e provided in the visible surface portion 21c overlap with each other.

[0022] The frame side member 40 is attached to the metal vertical frame 21 by inserting countersunk screws 6 into the four insertion holes 40e provided in the frame side plate portion 40b, respectively, and then threading them into the insertion holes 21e in the visible surface portion 21c and into the screw holes 5b provided in the fixing plate 5. That is, as shown in FIG. 2 , the visible surface portion 21c is sandwiched between the fixing plate 5 and the frame side plate portion 40b, and the countersunk screws 6 are threaded in to sandwich the frame side plate portion 40b between the fixing plate 5 and the frame side plate portion 40b, thereby attaching the frame side member 40 to the metal vertical frame 21.

[0023] 4, when the frame side member 40 is attached to the metal vertical frame 21, the upper screw 7 that secures the fixing plate 5 to the frame side plate portion 40b is positioned higher than the upper end 40g of the rotation shaft 40a of the frame side member 40, and the lower screw 7 is positioned lower than the lower end 40h of the shaft portion 40c of the frame side member 40. In addition, the interior-side edge 5c of the fixing plate 5 is positioned closer to the interior than the interior-side edge 40f of the frame side plate portion 40b.

[0024] According to the fitting 1 of this embodiment, in the hinge 4 that rotatably attaches the door 3, the frame side panel portion 40b that is fixed to the visible surface portion 21c of the vertical frame 20 is fixed with the metal fixing plate 5 by the countersunk screws 6 while sandwiching the visible surface portion 21c, so that the visible surface portion 21c is reinforced by the fixing plate 5. Therefore, it is possible to suppress deformation of the visible surface portion 21c due to external forces transmitted from the door 3 via the hinge 4.

[0025] Furthermore, external forces transmitted from the door 3 are transmitted to the frame 2 via the hinges 4. Therefore, when a moment acting in the in-plane direction of the door 3 occurs, the external force acts on the frame side plate 40b, centered on the engagement between the pivot shaft 40a and the door side member 41. Therefore, by arranging the screws 7 that secure the fixing plate 5, which sandwiches the projection surface 21c together with the frame side plate 40b, to the projection surface 21c at intervals in the vertical direction and positioning the upper screw 7 higher than the upper end 40g of the pivot shaft 40a, it is possible to suppress deformation of the projection surface 21c even when a moment acting in the in-plane direction of the frame side plate 40b is applied. This makes it possible to provide a fitting 1 in which the vertical frame 20 is less likely to deform even when an external force transmitted from the door 3 is applied.

[0026] Furthermore, the interior-side edge 5c of the fixing plate 5 is located closer to the interior than the interior-side edge 40f of the frame side plate portion 40b of the attached hinge 4, so even if an external force acts on the door 3 and the interior-side edge 40f of the frame side plate portion 40b acts to press the visible surface portion 21c towards the fixing plate 5, the fixing plate 5 will prevent deformation such as pushing in the visible surface portion 21c. This makes it possible to provide a fitting 1 equipped with a vertical frame 20 that is less likely to deform.

[0027] Furthermore, the position of at least one of the two screws 7 that secure the fixing plate 5 to the visible surface 21c is lower than the lower end 40h of the shaft 40c, so the fixing plate 5 to which the frame side plate 40b of the hinge 4 is secured is secured by two screws 7 that are widely spaced apart above and below. This further reduces in-plane rotation of the fixing plate 5 and the frame side plate 40b, making it possible to further suppress deformation of the visible surface 21c due to external forces transmitted from the door 3.

[0028] In the above embodiment, an example was described in which the center of the upper screw 7 that fixes the fixing plate 5 to the frame side plate portion 40b is located above the upper end 40g of the pivot shaft 40a, but the position of the upper screw 7 may be at the same height as or higher than the upper end 40g of the pivot shaft 40a. Also, the position of the upper screw 7 may not be at the center of the screw 7, but may be such that the lower end of the head of the screw 7 is at the same height as or higher than the upper end 40g of the pivot shaft 40a.

[0029] In the above embodiment, an example in which the fixing plate 5 is fixed to the frame side plate portion 40b with two screws 7 has been described, but this is not limiting. For example, the fixing plate 5 may be fixed with three or more screws 7, as long as at least one of the screws 7 is positioned higher than the upper end 40g of the rotation shaft 40a. In this case, it is more preferable that at least one of the multiple screws 7 is positioned lower than the lower end 40h of the shaft portion 40c.

[0030] In the above embodiment, an example was described in which the frame body 2 to which the door 3 is attached via hinges 4 is framed by a composite frame material in which a metal vertical frame 21 and a resin vertical frame 22 are engaged and joined together, but the frame material that makes up the frame body is not limited to a composite frame material and may be a frame body made of a single member such as metal or resin.

[0031] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. The present embodiment includes at least the following inventions.

[0032] A fixture comprising a frame body to be attached to a building, and a door body rotatably attached to a vertical frame of the frame body via a hinge, wherein the hinge comprises a frame side member having a frame side panel portion fixed to a projected surface portion of the vertical frame that forms a projected surface, and an axle portion provided at the outside end of the frame side panel portion and having a rotation axis extending upward, and a door body side member fixed to the door body and engaging with the rotation axis to rotate, wherein the frame side panel portion is fixed to the vertical frame by clamping the projected surface portion together with a metal fixing plate fixed to the projected surface portion by a plurality of fixing devices arranged at intervals in the vertical direction, and the position of at least one of the plurality of fixing devices is at the same height as or higher than the tip of the axle portion.

[0033] In this type of fixture, in the hinge that rotatably attaches the door body, the frame side panel that is fixed to the projected surface of the vertical frame clamps the projected surface together with the metal fixing plate and is fixed with a fixing device, so the projected surface is reinforced by the fixing plate, making it possible to suppress deformation of the projected surface due to external forces transmitted from the door body.

[0034] Furthermore, external forces transmitted from the door body are transmitted to the frame body via the hinge. Therefore, when a moment acting in the in-plane direction of the door body is generated, the external force acts on the frame side plate portion, centered on the engagement part between the pivot shaft and the door body side member. For this reason, by arranging multiple fasteners at intervals in the vertical direction to fasten the fixing plate, which sandwiches the projection surface portion together with the frame side plate portion, to the projection surface portion, and by positioning one of them at the same height as the tip of the pivot shaft or higher than the tip of the pivot shaft, it is possible to suppress deformation of the projection surface portion even when a moment acting in the in-plane direction of the door body is applied. This makes it possible to provide a fitting whose vertical frame is less likely to deform even when an external force transmitted from the door body via the hinge is applied.

[0035] Such a fixture is characterized in that the interior side edge of the fixing plate is located closer to the interior side than the interior side edge of the frame side plate portion.

[0036] With this type of fitting, the interior edge of the fixed plate is positioned closer to the interior than the interior edge of the frame side plate of the attached hinge, so even if an external force acts on the door body and the interior side of the frame side plate acts to press the visible surface toward the fixed plate, the fixed plate will prevent the visible surface from being pushed in. This makes it possible to provide fittings with vertical frames that are less likely to deform.

[0037] Such a fixture is characterized in that the position of at least one of the plurality of fasteners is lower than the lower end of the shaft portion.

[0038] In this type of fitting, at least one of the multiple fasteners that secure the fixing plate to the recessed surface is positioned lower than the bottom end of the shaft, so the fixing plate to which the hinge frame side plate is fixed is secured by two fasteners that are widely spaced above and below. This further reduces in-plane rotation of the fixing plate and frame side plate, making it possible to further reduce deformation of the recessed surface due to external forces transmitted from the door body.
