Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening device in a building room, and more particularly to an opening device having a compact opening / closing mechanism.

[0002]

2. Description of the Related Art Conventionally, a pivot hinge or a hinge mechanism has been used as an opening / closing mechanism for an indoor door. For example, Japanese Patent No. 2780962 discloses a pivot hinge as shown in FIG. In FIG.
The door body 74 is attached to the frame body 75 via an upper pivot hinge 70 and a lower pivot hinge (not shown). The upper pivot hinge 70 has a vertical axis 71 and an axis 7
1, and two horizontal members 72 and 73 having horizontal planes that are parallel to each other and are rotatably provided. The upper surface of the horizontal member 72 is attached to the lower surface of the upper frame of the frame body 75, and the lower surface of the horizontal member 73 is attached to the upper end surface of the door body 74. Then, by rotating the horizontal member 73 around the shaft 71 with respect to the horizontal member 72 fixed to the frame body 75, the opening / closing operation of the door body 74 with respect to the frame body 75 is realized.

On the other hand, for example, Japanese Patent Application Laid-Open No. 11-107609 discloses an example of a hinge mechanism as shown in FIG. In FIG. 12, the door body 88 is attached to the frame body 89 via an upper hinge mechanism 80a and a lower hinge mechanism 80b. In FIG. 12, the hinge mechanism 80
In order to clearly show a and 80b, the upper and lower parts are enlarged and displayed, and the central part is omitted. In the following description of the hinge mechanism of FIG. 12, when distinguishing between the upper and lower hinge mechanisms, “a” and “b” are added after the reference sign, and when it is not necessary, “a” and “b” are added after the reference sign. ] And “b” are not added.

In FIG. 12, a hinge mechanism 80 includes a vertical shaft 81, and vertical parts 82 and 8 each having a vertical shaft 81 and two vertical surfaces which are rotatably provided around the shaft 81 and which are vertically arranged.
3 and 3. Then, one surface side of the vertical portion 82 is a side end surface of the door body 88, and one surface side of the other vertical portion 83 is a frame body 89.
It is attached to the vertical frame of. Then, by rotating the vertical portion 82 around the shaft 81 with respect to the vertical portion 83 fixed to the frame body 89, the opening / closing operation of the door body 88 with respect to the frame body 89 is realized. Further, in this hinge mechanism, the vertical portion 83 is composed of two plane plates arranged on the front side and the back side of the paper, and the positional relationship between these two plane plates is adjusted by adjusting screws 84 to 86. By relatively changing the positions of the frame 89 and the door 88, the positions of the frame 89 and the door 88 in the left-right direction and the front / back direction with respect to the opening surface can be finely adjusted. Further, the shaft 81b of the lower hinge mechanism 80b
The tip of the adjusting screw 87 that has a common axis with the axis of
By finely adjusting the positions of the frame body 89 and the door body 88 in the vertical direction, it is possible to bring them into contact with the upper end portion of 1b and rotate the adjusting screw 87 to move the vertical direction.

[0005]

However, since the pivot hinge has a structure in which two members having parallel horizontal planes rotate about a vertical axis, the above-mentioned two members are inevitable on the open side of the door body. There was a problem that it protrudes so as to project, which becomes a constraint on the design of the indoor opening. In particular, when the door body is to be rotated by 180 °, there is a problem in that the overhanging length has to be increased considerably. Also,
Due to its structure, the pivot hinge makes it difficult to incorporate an adjustment mechanism that finely adjusts the relative positional relationship between the frame body and the door body,
There is also a problem that a relatively large-scale installation work is required when actually performing fine adjustment.

On the other hand, since the hinge mechanism requires two planes in the vertical direction, the shaft has to be long in the vertical direction, and the tubular shaft support portion is long even when the door is closed. There was a problem that it became conspicuous and became a design constraint here.

In addition, in recent westernized houses, high-rise condominiums, etc., there is a demand for a compact size opening / closing mechanism that is inconspicuous in harmony with a modern design door body.

Therefore, the present invention provides an adjusting mechanism that is compact in size and is inconspicuous, can rotate 180 ° without providing a large overhanging portion, and finely adjusts the relative position between the door body and the frame body. It is an object of the present invention to provide an opening device provided with an opening / closing mechanism that is provided inside and is less likely to be a constraint in design.

[0009]

The present invention will be described below. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated forms.

A first aspect of the present invention is an opening device including a frame body (1) and a door body (2) attached to the frame body so as to be openable and closable via an opening / closing mechanism (3, 4). In, the opening / closing mechanism is attached to the frame body and rotates around a fixed hinge (3b, 4b) having a horizontal surface at least in part and a vertical axis passing through a point in the horizontal surface of the fixed hinge. And a rotating portion (3a, 4a) having a vertical surface,
The opening device (10) is characterized in that the door body is attached to the rotating part to solve the above problems.

The opening / closing mechanism of the opening device of this aspect is, so to speak, a pivot hinge (horizontal member) attached to the frame body and a hinge (vertical member) attached to the door body around a vertical axis. It is rotatably attached to.
Therefore, since the horizontal member and the vertical member are combined in the orthogonal direction via the vertical axis, the size of the opening / closing mechanism as a whole can be made compact and the protruding portion from the opening can be minimized. You can

A second aspect of the present invention is an opening device comprising a frame body and a door body which is attached to the frame body so as to be openable and closable via the opening and closing mechanism. The opening and closing mechanism is attached to the frame body. A fixed hinge having a horizontal surface at least in part, and a rotating portion having a vertical surface that rotates around a vertical axis passing through a point in the horizontal surface of the fixed hinge,
The door body is attached to the rotating portion, and the opening / closing mechanism is further provided with an adjusting mechanism (28a, 28b, 29, 47, 48) capable of adjusting the relative position of the door body with respect to the frame body. The opening device is characterized in that

According to the opening device of this aspect, since the rotating part attached to the door side of the opening / closing mechanism can have a structure similar to that of the conventional hinge mechanism, this part is incorporated in the conventional hinge mechanism. It is possible to incorporate an adjusting mechanism similar to the adjusting mechanism used. Therefore, while realizing a compact size of the opening / closing mechanism, it is possible to easily adjust the delicate positional relationship between the frame body and the door body during construction immediately after construction.

A third aspect of the present invention is an opening provided with a frame body and a door body attached to the frame body so as to be openable and closable via an upper opening / closing mechanism (3) and a lower opening / closing mechanism (4). In the device, the upper opening mechanism and the lower opening mechanism are respectively
A fixed hinge that is attached to the frame body and has a horizontal surface at least in part, and a vertical surface that rotates around a vertical axis passing through one point in the horizontal surface of the fixed hinge and that has a door body. The lower opening / closing mechanism is provided with a rotating part to be mounted and a shaft (23, 55) sharing a vertical axis, and the shaft attached to either the fixed hinge or the rotating part is vertically inserted into the other. The fixed hinge and the rotating part are configured as possible, and the shaft attached to either the fixed hinge or the rotating part in the upper opening / closing mechanism can be fitted into the other from a substantially horizontal direction. A fixed hinge and a rotating portion are configured, and in a state where the door body is assembled to the frame body via the upper and lower opening / closing mechanisms, a vertical direction between the lower surface of the fixed hinge and the upper end surface of the rotating body in the upper opening / closing mechanism. The direction distance is It is an opening device according to claim is provided shorter than the fitting length of the shaft in the section opening and closing mechanism.

According to the opening device of this aspect, the door body is first locked to the frame body by the lower opening / closing mechanism, and then the door body is raised to fix the axis of the upper opening / closing mechanism in the horizontal direction by the fixed hinge or the rotation. The door body can be easily hung on the frame body by fitting the parts. Also, for example, when there is an object in the lower part and the door body climbs on it, the upper end surface of the rotating part of the upper opening / closing mechanism interferes with the lower surface of the fixed hinge before the shaft falls out in the lower opening / closing mechanism, and the movement is restricted. Therefore, the door body can be prevented from falling off the frame body.

A fourth aspect of the present invention is a frame body (1) and a door body (2) attached to the frame body so as to be openable and closable via an upper opening / closing mechanism (3) and a lower opening / closing mechanism (4). In the opening device (10) including the above, the upper opening / closing mechanism is attached to the upper frame of the frame body, and the upper fixed hinge (3b) is provided with a horizontal surface at least in part, and the horizontal surface of the upper fixed hinge. An upper rotating part (3a) having a vertical surface that rotates around a vertical axis passing through a point inside, and the lower opening / closing mechanism is attached to a vertical frame of the frame and at least partially horizontal. Fixed hinge (4b) having a flat surface, and a lower rotating portion (4a) having a vertical surface that rotates around a vertical axis passing through a point in the horizontal surface of the fixed hinge. ,
The door body is attached to the upper rotating portion and the lower rotating portion, and is an opening device.

According to the opening device of the fourth aspect, since the upper fixed hinge is attached to the upper frame, the upper fixed hinge can be formed of a member having a flat surface. Therefore, since the structure is simple, it is possible to reduce the labor and cost at the time of manufacturing. Moreover, since it is sufficient to consider only one plane when mounting, positioning can be facilitated. On the other hand, since the lower fixed hinge has a vertical surface that abuts on the vertical frame and a horizontal plane that is orthogonal to the vertical surface, it can be freely moved in the vertical direction by adjusting the contact position of the vertical surface on the vertical frame. The mounting position can be determined. In particular, such a structure is useful in forming a barrier-free opening.

The operation and the advantage of the present invention will be apparent from the embodiments described below.

It is possible to prevent the portion 3a from falling off the fixed hinge 3b (see FIG. 3B).

As described above, in the upper opening / closing mechanism 3, the fixed plate 32 of the fixed hinge 3b is attached to the upper frame of the frame body 1, and the rotating portion 3a is attached to the side end surface of the door body 2. Therefore, the fixed hinge 3b and the rotating portion 3a are in a positional relationship of being respectively arranged on two orthogonal planes.
Therefore, the size of the entire opening / closing mechanism can be made compact, and the overhanging length in the horizontal direction can be kept small. Further, since the structure of the rotating portion 3a attached to the door body 2 is basically the same as that of the conventional hinge mechanism, the door body position fine adjustment mechanism applicable to the conventional hinge mechanism can be applied as it is. .

Since the fixing plate 32 is mounted on the upper frame, it is only necessary to form a flat plate into a predetermined shape, and there is an advantage that it is easy to process and does not require much labor. It is also possible to configure this so that it can be attached to the vertical frame.
In this case, the fixing plate has a shape including two planes folded at right angles. Therefore, it takes more time to process as compared with the case of attaching to the upper frame. However, there is an advantage that the mounting position can be freely determined on the vertical frame.

FIG. 4 shows the rotating portion 4a of the lower opening / closing mechanism 4,
FIG. 5 is a diagram showing the fixed hinges 4b of the lower opening / closing mechanism 4, respectively.

The door body mounting portion 42 is mounted on the connecting portion 44 via an adjusting mechanism, and the door body mounting portion 42 is mounted on the door body 2. Fine adjustment of the relative positions of the connecting portion 44 and the door mounting portion 42 in the left-right direction and the front / back direction is performed by an adjusting mechanism. These configurations are the same as those of the upper opening / closing mechanism 3 and have already been described, so description thereof will be omitted here.

In FIG. 5, (a) shows a fixed hinge 4b.
And (b) are front views, respectively. The fixed hinge 4b includes a hinge main body 50 and a shaft 55 attached to the hinge main body 50. The hinge body 50 is
A vertical portion 51 formed by a vertical surface, and a horizontal portion 5 formed to extend in the horizontal direction from the lower end of the vertical portion 51.
2 and. A vertical axis 5 is provided at one end of the horizontal portion 52.
5 is attached so as to vertically pass through the horizontal portion 52. The diameter of the shaft 55 is slightly smaller than the inner diameter of the fitting hole 49 of the rotating portion 4a. The shaft 55 is the horizontal portion 52.
The hinge main body 50 and the shaft 55 are integrally formed. A disc-shaped receiving member 56 made of a material having solid lubricity is provided around the shaft 55 on the upper surface of the horizontal portion 52.

[0058]

As described above, according to the opening device of the first aspect, since the horizontal member and the vertical member are combined in the orthogonal direction via the vertical axis, the opening / closing mechanism as a whole is opened. The size can be made compact, and the protruding portion from the opening can be minimized.

Further, according to the opening device of the second aspect, since the rotating portion attached to the door side of the opening / closing mechanism can have a structure similar to that of the conventional hinge mechanism, the hinge mechanism of the related art is provided at this portion. It is possible to incorporate an adjustment mechanism similar to that incorporated in the. Therefore, while realizing a compact size of the opening / closing mechanism, it is possible to easily adjust the delicate positional relationship between the frame body and the door body during construction immediately after construction.

According to the opening device of the third aspect, the door body is first locked to the frame body by the lower opening / closing mechanism, and then the door body is raised to horizontally fix the axis of the upper opening / closing mechanism by a hinge or a hinge. The door can be easily hung on the frame by fitting the moving part. Also, for example, there is an object at the bottom,
When the door body rides on it, the upper end surface of the rotating part of the upper opening / closing mechanism interferes with the lower surface of the fixed hinge to restrict the movement of the door before the shaft falls out of the lower opening / closing mechanism. It can be prevented from falling out.

Further, according to the opening device of claim 4,
Since the upper fixed hinge is attached to the upper frame, the upper fixed hinge can be configured by a flat member. Therefore, since the structure is simple, it is possible to reduce the labor and cost at the time of manufacturing. Moreover, since it is sufficient to consider only one plane when mounting, positioning can be facilitated. On the other hand, since the lower fixed hinge has a vertical surface that abuts on the vertical frame and a horizontal plane that is orthogonal to the vertical surface, the lower fixed hinge can be freely moved in the vertical direction by adjusting the contact position of the vertical surface on the vertical frame. The mounting position can be determined. In particular, such a structure is useful in forming a barrier-free opening.
