[0009] An opening device according to one embodiment will be described with reference to the drawings, taking as an example an entrance door supported by hinges so as to be freely opened and closed on a frame body installed at an opening of a building. (Overall composition) The entrance door of this embodiment is an entrance door in which a door body 1 is supported via a plurality of hinges 8 so as to be freely opened and closed, as shown in FIG.

[0010] As shown in Figure 2(a), the hinge 8 supporting the front door has a pair of blades 81, 82 arranged above and below, and a connecting shaft 83 that connects the blades 81, 82 to each other so that they can rotate freely. The connecting shaft 83 is positioned on the outside of the room and the pair of blades 81, 82 are fixed to the door body 1 and frame 2, respectively, thereby supporting the door body 1 so that it can be opened freely to the outside of the room.

[0011] A pair of wings 81, 82 of the hinge 8 each have a wing portion 811, 821 fixed to the outer peripheral surface of the door body 1 or the inner peripheral surface of the frame body 2, and a bearing portion 812, 822 provided on one side of the wing portion 811, 821 and supported by a connecting shaft 83. The blade 82 arranged on the frame side has the blade portion 821 arranged on the inner surface of the frame body 2, and is connected to a back plate 92 arranged inside the frame body 2 by mounting screws b2, and is fixed to the inner surface of the frame body 2.

[0012] On the other hand, the blade 81 on the door body side of the hinge 8 has the blade portion 811 arranged on the outer peripheral surface of the hanging side of the door body 1, and is connected to a back plate 91 arranged on the inside of the door body 1 by a mounting screw b1, and is fixed to the door body 1.

[0013] If necessary, a hinge spacer 5 is sandwiched between the blade portion 811 of the blade 81 on the door body side of the hinge 8 and the outer peripheral surface of the door body 1, and by adjusting the distance between the hinge 8 and the door body 1, it is possible to install the door body 1 in an appropriate position. The hinge spacer 5 of this embodiment will be further described below.

[0014] (hinge spacer) In this embodiment, the blade 81 on the door body side of the hinge 8 has four screw holes formed in the blade portion 811 for passing through mounting screws. Specifically, as shown in FIG. 3(a), blade portion 811 of blade 81 has a total of four screw holes: screw holes 811a, 811b lined up vertically on the inside of the room when the door body 1 is viewed from the hanging side, and screw holes 811c, 811d lined up vertically on the outside of the room. The screw holes 811a, 811b lined up on the inside of the room are positioned higher than the screw holes 811c, 811d lined up on the outside of the room.

[0015] As shown in Figures 2(b) and 3(c), the blade 81 is fixed to the door body 1 by four mounting screws b11, b12, b13, and b14 passing through each of the screw holes 811a, 811b, 811c, and 811d, respectively, and screwing them into the back plate 91.

[0016] The hinge spacer 5 of this embodiment is made of a metal material such as steel, and as shown in Figure 3(b), is a rectangular plate-shaped member with three diagonal cuts 5a, 5b, 5c that are open at the bottom, and a handle portion 51 is provided at the upper part.

[0017] The diagonal cuts 5a, 5b, and 5c formed in the hinge spacer 5 have the same angle as the line connecting the screw hole 811b formed downward on the inside of the room and the screw hole 811c formed upward on the outside of the room in the blade 81 of the hinge 8, as shown in Figure 3(a).

[0018] As shown in Figure 3(c), when the hinge spacer 5 is clamped between the blade 81 and the outer peripheral surface of the door body 1, a mounting screw b12 that passes through a screw hole 811b formed downward on the inside of the hinge 8 of the blade 81 and a mounting screw b13 that passes through a screw hole 811c formed upward on the outside of the hinge 8 are fitted into a notch 5b formed in the middle. In addition, a mounting screw b11 that passes through a screw hole 811a formed above on the indoor side of the wing 81 of the hinge 8 is fitted into the notch 5a formed above, and a mounting screw b14 that passes through a screw hole 811d formed below on the outdoor side of the wing 81 of the hinge 8 is fitted into the notch 5c formed below.

[0019] Furthermore, as shown in Figures 3(b) and (c), when the hinge spacer 5 is clamped between the blade 81 and the outer peripheral surface of the door body 1, the handle portion 51 provided on the upper part protrudes from above the blade 81 of the hinge 8, and a hole 51c is provided in the handle portion 51. The hinge spacer 5 is formed such that the indoor side 51a and the outdoor side 51b of the handle portion 51 are at the same angle as the oblique cuts 5a, 5b, 5c formed in the hinge spacer 5.

[0020] (Door body installation procedure using hinge spacers) The procedure for installing a door body using a hinge spacer will be explained. The back plates 91, 92 are fixed to the door body 1 and the frame 2 in advance. Taking door body 1 as an example, a back plate 91 is placed on the inside of the hanging side of door body 1, and a screw b3 is inserted through the hanging side outer peripheral wall of door body 1 from the outer periphery side and screwed into back plate 91, thereby fixing back plate 91 to the inside of door body 1.

[0021] Next, the blades 82 of the hinge 8 are brought into contact with the inner peripheral surface of the frame 2, and the mounting screws b2 are passed through the screw holes of the blades 82 and screwed into the back plate 92, thereby fixing the blades 82 of the hinge 8 to the inner peripheral surface of the frame 2. Also, the blades 81 of the hinge 8 are brought into contact with the outer peripheral surface of the door body 1, and the mounting screws b11, b12, b13, and b14 are passed through the screw holes 811a, 811b, 811c, and 811d of the blades 81 and screwed into the back plate 91, thereby attaching the blades 81 of the hinge 8 to the outer peripheral surface of the door body 1.

[0022] Thereafter, the door body 1 is attached to the frame 2, and the door body 1 is supported by the hinges 8 on the inner periphery of the frame 2 so as to be capable of being opened and closed freely. If the position of the door body 1 relative to the frame 2 is misaligned in the left-right direction, a hinge spacer 5 is appropriately inserted between the outer peripheral surface of the door body 1 and the blades 81 of the hinge 8 to adjust the position of the door body 1.

[0023] Specifically, the mounting screws b11, b12, b13, and b14 that secure the blades 81 of the hinge 8 to the back plate 91 are loosened to form a gap between the blades 81 and the outer circumferential surface of the door body 1. At the same time, the screw b3 that secures the back plate 91 to the door body 1 is loosened to form a gap between the head of the screw b3 and the door body 1. As shown in Figures 2(b) and 3(a) and (c), the blade 81 of the hinge 8 has a hole 811e formed between the lower screw hole 811b on the inside of the room and the upper screw hole 811c on the outside of the room. When the blade 81 is fixed to the outer peripheral surface of the door body 1, this allows the head of the screw b3 fixing the back plate 91 to escape and at the same time makes it possible to operate the screw b3 from the outer peripheral side via the hole 811e.

[0024] Next, as shown in FIG. 4, an appropriate number of hinge spacers 5 are inserted into the gap formed between the blades 81 and the outer peripheral surface of the door body 1, and the inserted hinge spacers 5 are removed to adjust the position of the door body 1 relative to the frame 2. In the hinge spacer 5 of this embodiment, the notches 5a, 5b, and 5c are formed at an angle so that they go downward as they go from the outside of the room to the inside of the room, so that the mounting screws b11, b12, b13, and b14 and the screw b3 for fixing the back plate 91 can be inserted into the gap from above the outside of the blade 81 while fitting them into the notches 5a, 5b, and 5c, and the hinge spacer 5 can be inserted or removed without interfering with the bearing portion 812 of the hinge 8.

[0025] After inserting an appropriate number of hinge spacers 5 into the gap between the blade 81 and the outer peripheral surface of the door body 1, the installation of the door body 1 is completed by tightening the mounting screws b11, b12, b13, b14 and the screw b3 for fixing the back plate 91.

[0026] (Effects of the opening device of the embodiment) In the front door of this embodiment, by sandwiching a hinge spacer 5 between the door body 1 and the blades 81 of the hinge 8, any misalignment of the door body 1 caused by distortion of the building or dimensional errors can be corrected with a simple operation, thereby improving workability.

[0027] In the front door of this embodiment, the notches 5a, 5b, 5c provided in the hinge spacer 5 are formed by diagonal notches 5a, 5b, 5c that open downward. Therefore, when the hinge spacer 5 is clamped between the door body 1 and the wing 81 of the hinge 8, it can be inserted from above the wing 81 of the hinge 8 so that the mounting screws b11, b12, b13, b14 that secure the hinge 8 can be fitted into the notches 5a, 5b, 5c. Therefore, when the hinge spacer 5 is inserted, it does not interfere with components on the indoor or outdoor side of the hinge 8, making installation easy.

[0028] In the front door of this embodiment, a handle portion 51 is provided above the hinge spacer 5, protruding from the blade 81 of the hinge 8, and the indoor side 51a and the outdoor side 51b of the handle portion 51 are formed on sides having an inclination angle similar to the inclination angles of the notches 5a, 5b, and 5c. Therefore, as shown in Figure 5(a), the removal direction x1 of the hinge spacer 5 can be inferred from the indoor side 51a and the outdoor side 51b of the handle portion 51 when it is clamped between the door body 1 and the blade 81 of the hinge 8. As shown in Figure 5(b), when replacing the hinge spacer 5, the handle portion 51 can be picked up by hand and smoothly removed in the removal direction x1. It can also be used to reaffirm that the hinge spacer 5 is inserted at an angle during installation, improving ease of installation.

[0029] In the hinge spacer 5 of this embodiment, a hole 51c is formed in the handle portion 51 protruding from the wing 81 of the hinge 8, so that the hinge spacer 5 can be removed by hooking a tool such as a screwdriver into the hole 51c.

[0030] The hinge spacers 5 may be attached by inserting or removing them from below the hinges 8 as appropriate. Specifically, as shown in Figures 6 and 7, the hinge spacer 5 may be inserted from the lower side on the indoor side of the door body 1 toward the upper side on the outdoor side. By inserting or removing the hinge spacer 5 from below, the hinge spacer 5 can be inserted relatively easily even for large doors by operating from below. Incidentally, the same hinge spacer 5 can be used, and since there is no significant difference in structure between the hinge 8 and the hinge spacer 5, the same reference numerals are used in Figs. 6 and 7, and detailed description thereof will be omitted.

[0031] (Other embodiments) As shown in FIG. 8(a), the hinge spacer 5 may be formed of a plate material in which two hinge spacers 5 having the same shape as in the previous embodiment are arranged in line symmetry and connected by a thin portion 52. By bending the two hinge spacers 5 at the thin-walled portion 52, a hinge spacer 5 having twice the thickness can be formed, and by cutting at the thin-walled portion 52, two hinge spacers 5, 5 can be manufactured.

[0032] In addition, as shown in FIG. 8(a), the left and right sides 51d, 51e of the hole 51c provided in the handle portion 51 may be angled at the same angle as the notches 5a, 5b, 5c to indicate the removal direction of the hinge spacer 5. Furthermore, as shown in FIG. 8(b), the hinge spacer 5 may be provided with an arrow 53 at the same angle as the notches 5a, 5b, and 5c on the handle portion 51 to indicate the removal direction of the hinge spacer 5, and the configuration for indicating the removal direction provided on the handle portion 51 is not limited in any way. In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
