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 "visible surface of the vertical frame" means the front portion of the vertical frame.

[0009] <First embodiment> FIG. 1 shows a fitting device equipped with an example of a fitting frame reinforcement according to the present invention. This fitting device 1 comprises a fitting frame 10 that is attached to the inner edge of an opening in a building frame, and an opening / closing body 20 that rotates to open and close inside this fitting frame 1, and constitutes a hinged door device. In this fitting device 1, fitting frame reinforcements 30 are attached to the upper right corner and the upper left corner of the fitting frame 10, respectively.

[0010] The fitting frame 10 is configured to have an inverted concave shape when viewed from the front, and is made up of vertical frames 11, 11 erected at an interval on the left and right, and an upper frame 12 connecting the upper ends of these vertical frames 11, 11. The lower immovable surface F of this fitting frame 10 is the floor surface in the illustrated example, but it may also be a bottom frame or a door sill that connects the lower ends of the vertical frames 11, 11.

[0011] The vertical frame 11 and the upper frame 12 are each a long member made of hard metal. The vertical frame 11 has a convex frame-like cross section extending vertically in an elongated shape. The upper frame 12 has a rectangular frame-like cross section that is continuous and elongated in the left-right width direction. The end of the upper frame 12 is formed in a concave shape, and this concave portion fits into a convex portion on the outer surface of the upper frame 12 (see Figs. 1 and 5).

[0012] The convex portion of the vertical frame 11 is continuous in the vertical direction, and below the upper frame 12, it functions as a door-stop surface that receives the opening / closing body 20 when closed.

[0013] The vertical frame 11 and the upper frame 12 protrude an appropriate amount toward the front from the structural wall surface A on which the fitting device 1 is to be installed. For example, according to Fig. 3, the vertical frame 11 protrudes toward the front from the structural wall surface A by a protrusion dimension x1.

[0014] The sight surface 11b of the vertical frame 11 is located closer to the viewer than the surface 12a of the upper frame 12 which is approximately parallel to the sight surface 11b (see FIG. 3). That is, the vertical frame 11 has a rounded convex curved surface 11a at the front corner in its cross section, and this convex curved surface 11a protrudes toward the front side from the surface 12a of the upper frame 12. Therefore, a step x2 is formed between the visible surface 11b of the vertical frame 11 and the surface 12a of the upper frame 12.

[0015] The opening / closing body 20 is made up of two metal outer plates spaced apart in the thickness direction and supported by framework or core material between them, and is configured in the shape of a rectangular plate that fits inside the frame of the door and window frame 10. One end of this opening / closing body 20 in the width direction is supported by one vertical frame 11 via a hinge (not shown), and the other end forms a hinged door that can be rotated to open and close. According to FIG. 1, the opening / closing body 20 is opened by rotating in one direction (toward the rear in FIG. 1) and is closed by rotating in the other direction (toward the front in FIG. 1). The opening / closing body 20 in the closed state is close to or in contact with a convex portion (door stop portion) on the inner side of the vertical frame 11. In the figure, reference numeral 21 denotes a handle for operating the opening / closing body 20 to open or close it.

[0016] The fitting frame reinforcement 30 reinforces the connection between the vertical frame 11 and the top frame 12 of the fitting frame 10. This fitting frame reinforcement 30 is fastened and fixed by a plurality of fasteners 13 to the surface of the fitting frame 10 on the side not in the rotation range of the opening / closing body 20 (the front side surface in FIG. 1).

[0017] This door frame reinforcement 30 integrally comprises a vertical piece 31 which is overlapped and fastened to the visible surface 11b of the vertical frame 11, a horizontal piece 32 which is overlapped and fastened to the surface 12a of the upper frame 12 which is approximately parallel to the visible surface 11b, and an inclined piece 33 which diagonally connects the vertical piece 31 and the horizontal piece 32 (see Figure 2). This building frame reinforcement 30 is formed from a hard material having appropriate strength, and is formed, for example, by pressing or bending a hard metal plate into a triangular shape when viewed from the front, having a vertical piece 31, a horizontal piece 32, and an inclined piece 33 integrally formed therewith.

[0018] The vertical piece portion 31 is a portion that overlaps and fits onto the visible surface 11b of the vertical frame 11 in the vertical direction. The vertical piece 31 is formed with a concave cross section that fits into the vertical frame 11, and its bent portion on the outside of the frame serves as a frame outside positioning piece 31a (positioning portion) that positions the visible surface 11b in the extension direction (the width direction in the example of FIG. 3). The frame outside positioning piece 31a contacts and overlaps with the surface of the vertical frame 11 on the outside of the frame.

[0019] The internal width W of this vertical piece 31 is set to be large so that a plurality of types of vertical pieces 31 having different width dimensions w can be fitted together (see FIG. 3). The vertical piece 31 fits into the vertical frame 11 with a gap s in the width direction between it and the inner side surface of the vertical frame 11. Therefore, the vertical piece 31 can be fitted into a vertical frame having a width dimension larger than that of the vertical frame 11 in the illustrated example, as long as the width dimension does not exceed the internal width W. Furthermore, even if the internal width W of the vertical piece 31 varies due to manufacturing errors or the like, the gap s can function as an appropriate play dimension, allowing the vertical piece 31 to fit satisfactorily with the vertical frame 11.

[0020] In the vertical piece 31, a plurality of fastening holes 31b through which fasteners 13 (for example, bolts, screws, rivets, etc.) are inserted are provided in a plate-like portion overlapping the facing surface 11b of the vertical frame 11. The fasteners 13 inserted into the fastening holes 31b are screwed into the vertical frame 11 and tightened.

[0021] The horizontal piece 32 is a plate-shaped portion that overlaps the front portion of the upper frame 12 in the width direction. A plurality of fastening holes 32b for inserting fasteners 13 are provided at intervals in the width direction in this horizontal piece portion 32. The fasteners 13 inserted into the fastening holes 32b are screwed into the upper frame 12 and tightened.

[0022] The inclined piece portion 33 is a triangular plate-shaped portion that connects the vertical piece portion 31 and the horizontal piece portion 32 (see FIG. 2). The inclined piece portion 33 is provided with a high-strength portion 33 a having a bending strength greater than those of the vertical piece portion 31 and the horizontal piece portion 32 .

[0023] The high-strength portion 33a is a rib that extends from the vertical frame 11 to the upper frame 12 and protrudes toward the front side. The high-strength portion 33a has a mountain-shaped cross section shown in FIG.

[0024] Therefore, according to the door frame reinforcement 30 configured as described above and the door device 1 equipped with this door frame reinforcement 30, the door frame reinforcement 30 can suppress deformation of the door frame 10 due to earthquakes, etc., and ultimately prevent malfunction of the opening and closing body 20 due to deformation of the door frame 10.

[0025] Furthermore, the fixture frame reinforcement 30 having the above-mentioned configuration can be easily attached to the fixture frame 10 of an existing fixture device 1, thereby contributing to increasing the strength of the existing fixture frame 10. In particular, according to a preferred example of this embodiment, since the internal width W of the vertical piece 31 is set to be relatively large, the vertical piece 31 can be fitted to various types of vertical pieces 31 having different width dimensions.

[0026] <Second embodiment> The above-mentioned fitting frame reinforcement 30 can be replaced with a fitting frame reinforcement 30' shown in FIG. The fixture frame reinforcement 30' is obtained by adding a frame outer positioning piece 32a to the fixture frame reinforcement 30 described above as a positioning portion for positioning the fixture frame 10 in the extension direction of the visible surface.

[0027] The frame outer positioning piece 32a is formed by bending the upper side of the vertical piece 31 toward the rear, and overlaps the upper frame 12 from the frame outer side (from above in FIG. 6). That is, the horizontal piece 32 contacts from the front surface of the upper frame 12 to the upper surface of the upper frame 12 so as to have an L-shaped cross section.

[0028] Therefore, with the above configuration, the door frame reinforcement 30' can be positioned in the vertical and horizontal directions relative to the door frame 10 by the frame outer positioning pieces 31a, 32a, and the door frame 10 can be effectively reinforced by this door frame reinforcement 30'.

[0029] <Third embodiment> A fitting frame reinforcement 30'' shown in Figs. 7 and 8 is obtained by removing the frame outer positioning piece 32a from the fitting frame reinforcement 30 described above and providing frame inner positioning pieces 31c, 32c.

[0030] The frame inner side positioning pieces 31c, 32c are provided on the upper corner side of the door / window frame 10 so as to overlap each other from the inside of the frame. More specifically, one of the frame inner positioning pieces 31c is formed as a convex piece that protrudes in the projection direction from the vertical piece portion 31 and contacts the inner surface of the vertical frame 11 in the vertical direction. The other frame inside positioning piece 32c is formed as a convex piece that protrudes in the projection direction from the horizontal piece portion 32 and contacts the lower surface of the upper frame 12 in the left-right direction.

[0031] According to the illustrated example, each frame inner positioning piece 31c (or 32c) is formed by making a concave cut in a front view in the plate-like portion of the door frame reinforcement 30 and bending the inner portion in the prospective direction. As another example of the frame inside positioning piece 31c (or 32c), a separate piece-like member may be fixed to the back surface of the fitting frame reinforcement 30 by welding or the like.

[0032] Therefore, according to the above configuration, the door frame reinforcement 30" can be positioned in the vertical and horizontal directions relative to the door frame 10 by the frame inner positioning pieces 31c, 32c, and the door frame reinforcement 30" can effectively reinforce the door frame 10.

[0033] <Third embodiment> The above-mentioned fitting frame reinforcement 30 can be replaced with a fitting frame reinforcement 30x shown in FIG. The door frame reinforcement 30x is the same as the door frame reinforcement 30 described above, except that the inclined piece 33 is replaced with an inclined piece 33'.

[0034] The inclined piece portion 33' is a portion that connects the upper side of the vertical piece portion 31 in the vertical direction (approximately the center in the illustrated example) and the portion that is wider in the horizontal direction than the horizontal piece portion 32 in the horizontal direction (approximately the center in the illustrated example), and is formed in a triangular shape that is smaller than the inclined piece portion 33 of the above-mentioned door frame reinforcement 30.

[0035] According to the fitting frame reinforcement 30x configured as described above, the amount of the space on the inner corner side where the vertical frame 11 and the top frame 12 intersect that is covered by the inclined piece portion 33' can be reduced. This reduces the possibility that an object passing through the frame will interfere with the inclined piece 33'.

[0036] <Modification> In the above embodiment, the vertical piece 31, the horizontal piece 32 and the inclined piece 33 are made into an integral member, but as another example, it is also possible to form a door frame reinforcement by integrally connecting the vertical piece 31, the horizontal piece 32 and the inclined piece 33, which are each separate.

[0037] In the above embodiment, the positioning parts for positioning the visible surface in the extension direction relative to the door frame 10 are configured as the frame outer positioning pieces 31a, 32a and the frame inner positioning pieces 31c, 32c. However, as another example of this positioning part, it may be configured so that a convex part provided on one of the door frame 10 and the door frame reinforcement 30 (30' or 30") is fitted into a concave part provided on the other.

[0038] In the above embodiment, the frame outer positioning piece or the frame inner positioning piece is provided for each door frame reinforcement, but as an example other than the illustrated example, it is also possible to provide both the frame outer positioning piece and the frame inner positioning piece for each door frame reinforcement.

[0039] In the above embodiment, the high-strength portion 33a is formed by bending a portion of the inclined piece portion 33. However, other examples of this high-strength portion include a portion in which a separate member is joined to the inclined piece portion 33, and a portion in which the plate thickness of the inclined piece portion 33 is increased.

[0040] In the above embodiment, the door frame reinforcement 30 (30' or 30") is attached to the door frame 10 in which the vertical frame 11 protrudes further forward than the upper frame 12. However, other examples of the door frame reinforcement include a mode in which it is attached to a door frame in which the upper frame protrudes further forward than the vertical frame, or a mode in which it is attached to a door frame in which the vertical frame and upper frame are approximately flush with each other.

[0041] In the above embodiment, the fixture frame reinforcement 30, 30' or 30" was provided on the fixture frame 10 of the fixture device 1, which is a hinged door, but the fixture frame reinforcement 30, 30' or 30" configured as described above can be attached to the fixture frame of a fixture device other than a hinged door, such as a sliding door, folding door, or balanced door, to reinforce the fixture frame. Furthermore, the above-mentioned fitting frame reinforcement 30, 30' or 30'' can also be attached to a window frame in a hinged door type window device or a sliding door type window device, etc., to reinforce the window frame.

[0042] 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.
