[0005]

FIG. 1 shows a state in which a hinge to which the present invention is applied is attached to a frame and a door. FIGS. It is shown for each of the two hinges B, which are two hinges, and for each of the closed and open states of the door. Also, FIG.
5 shows an example of the structure of the hinge. The structure of the hinge of the present invention will be described with reference to these drawings.

The A hinge 1 includes a first fixed blade 11 attached to the frame 100, a first rotating blade 12 attached to the door 200, a first intermediate blade 13 therebetween, the first fixed blade 11 and the first intermediate blade. A first frame-side shaft 14 for rotatably connecting the blade 13 and a first door-side shaft 15 for rotatably connecting the first intermediate blade 13 and the first rotary blade 12 are provided.

As shown in FIG. 1B, the B hinge 2 is attached at a position different from the position where the A hinge 1 is attached, for example, at a position vertically separated from the A hinge 1 and a frame 100.
The second fixed blade 21 attached to the door 200, the second rotating blade 22 attached to the door 200, the second intermediate blade 23 therebetween, and the second connecting the second fixed blade 21 and the second intermediate blade 23 rotatably. Frame side shaft 24, second intermediate blade 23 and second
A second door-side shaft 25 and the like that rotatably couple the rotary blade 22 to a position different from the first door-side shaft 15 in an arrow X direction that is a thickness direction of the door 200 are provided. FIG.
In (a), since the respective blades 21 and 22 are located above and below the A-th blade, the reference numerals are shown in parentheses.

A hinge 1 and B hinge 2 have screw holes 16 for attaching to frame 100 and door 200, respectively.
And 17 and 26 and 27 (FIG. 4,
5). FIG. 1B shows an example in which one hinge A is attached to the center and two hinges B are attached to the upper and lower sides of the hinge. However, each hinge may be installed in the opposite state. Good. Also, in this example, the A hinge 1 and the B hinge 2 are configured separately, but, for example, the respective fixed blades 11 and 21 are integrated, and both hinges are set as AB hinges to form one piece. It can be something. In this case, AB hinges are attached to, for example, two upper and lower portions of a frame and a door like ordinary hinges.

The first and second frame side shafts 14 and 24 are
It is provided such that a position distant from the one surface 201 in the X direction, that is, a center of each of the surfaces 201 is, for example, a position of O ₁ and O ₂ shown in FIG. This position is, as described below,
This is a position where the door 200 can be rotated on a fixed track by the first and second rotating blades 12 and 22. In FIG. 1, the position of the door 200 rotated by 90 ° in this manner is indicated by a two-dot chain line.

FIG. 6 shows a method of determining the positions of the first frame side shaft 14 and the second frame side shaft 24 when the door 200 is opened and closed as shown in FIG. 1, and the coaxial 14 determined by this method. , 2
The first door-side shaft 15 and the second door-side shaft 2 rotated by 4
5 shows the center trajectory. Then, the axis represents the initial position of the 15 and 25 as the center P _0, Q ₀ respectively show an intermediate position of the following Pi, Qi appropriate intervals partly as. These represent the trajectories of the centers of the shafts 15 and 25, and the movement of the door end surface slightly away from them.

As long as P ₀ and Q ₀ are located apart from each other, as shown in FIG. 1, in this embodiment, the cylindrical portions of the first and second rotating blades 12 and 22 The position is within the range of. However, it may be a position slightly closer to the inside or a position outside the thickness of the door. In this example, the door 200 is in a state of being in contact with the surface of the wall 300 on which the frame 100 is mounted when rotated by 90 °. In this state, the protrusion from the wall surface of the door is the same as the thickness T of the door and is minimized, and the width B of the opening when the door is opened can be maximized. However, when the hinge of the present invention is applied to various existing frames and doors, the door may be set slightly away from the wall surface.

As shown, when the door 200 rotates 90 °,
P ₁ to P _0, Q ₀ indicating the initial position indicates the final position _0, Q
It becomes _{1 0} . When these positional relationships are determined, the center O ₁ ,
O ₂ is first a bisector P of the line segment P ₀ −P _10.
And Q ₀ −Q ₁₀ on the bisector Q. As a result, when P ₀ and Q ₀ are rotated about O ₁ and O ₂ , their final positions necessarily reach P ₁₀ and Q ₁₀ .

Next, when P ₀ and Q ₀ are rotated about the centers O ₁ and O ₂ , respectively, the positions of O ₁ and O ₂ are selected so that the distance between them is maintained at an appropriate distance. I do. That is, for example, the center O ₁ is set to an appropriate position as shown in the drawing from the bisector P, and an arc locus R of the point P ₀ is drawn with the center O ₁ as a center. O ₂ is selected, and an arc locus S of the point Q ₀ is drawn with the O ₂ as a center. O ₂ is determined so that the locus S and the locus R do not cross each other more than the distance between P _{0 and} Q ₀ and do not intersect.

According to the hinges A and B with their respective axial positions determined in this way, the rotating blades and the door are located at the initial positions shown in FIGS. (B) is surely turned on a predetermined trajectory. In this case, since the positions of the center points O ₁ and O ₂ for determining the trajectory of the rotating blades are innumerable, the selection thereof is easy.

In this example, the position of the center O ₂ is set to a position close to the wall 300 on the bisector Q. In this case, P ₀ and Q ₀ are rotated earlier from the initial position. , Door 2
00 can be reliably avoided from contacting the free end side of the frame with the frame facing the free end side. However, this position is determined in accordance with the actual condition according to the dimensions of the door, the size of the gap between the door and the frame, and the like.

According to the hinge described above, the door is opened and closed as follows. For example, as shown in FIG.
With only the above, since the door 200 is supported by the fixed blade 11 via the two shafts 14 and 15, the degree of freedom of rotation of the door is increased and the trajectory thereof is not constant. However, according to the combination of A hinge 1 and B hinge 2, as shown in FIG. 6, O around the first link and O ₂ connecting the O ₁ -P ₀ around the O _{1 2} -Q the second link connecting _0, the spacing of the mutually rotating the P _0, Q ₀ which is constant over the rotating blade fixed to the end face of the door 200, P ₀ -Q
₀ means P ₁ −Q ₁ , P ₂ −Q ₂ , −−P ₅ , Q
_{5 ---- P 1 0, Q 1} 0 continue to rotate while taking a definite attitude and so on. Therefore, the end face of the door 200 constrained at the points P ₀ and Q ₀ via the rotating blades 11 and 21 also rotates on the determined orbit. As a result, the door 200 can be reliably turned and opened and closed on a predetermined fixed orbit.
In the fully opened position, the door surface 201 is arranged along the wall 300 so that the protrusion to the frontage of the door with the thickness T can be minimized.

[0017]

As described above, according to the present invention, the hinge is the first
The hinge is constituted by a combination of two types of hinges, a hinge and a second hinge, and each hinge is sequentially attached to a fixed blade-frame-side shaft-intermediate blade-door-side shaft-door attached to a frame. It consists of rotating blades, so that each hinge can be installed at a different position on the door, and each door side shaft is provided at a different position in the thickness direction of the door, so through these two types of hinges By attaching the door to the frame, the posture can be regulated to a fixed state.

Further, each frame-side shaft, which is a center when each door-side shaft rotates, is positioned at a position away from one surface of the door in the thickness direction, and the door is rotated with a fixed orbit by each rotating blade. Since the doors are provided in such a positional relationship as possible, the doors can be reliably opened and closed on a fixed track, and when the doors are fully opened, the doors can be displaced from the frame protruding from the wall and can be moved toward the wall surface.

The center position of such a frame-side axis is, for example,
First, the position of the target door at the time of opening is set, whereby the center position of the first door side axis and the second door side axis in the open and closed states of the door, that is, the first door side axis, The center of the first closed state and the center of the first open state and the center of the second closed state and the center of the second open state for the same second door-side axis are determined, and the center of the first closed state and the center of the first open state are determined. By selecting the bisector of the distance and the bisector of the distance between the center of the second closed state and the center of the second open state, selection is made on each of the bisectors. This selection is made so that when the center of each door-side axis is rotated about the center of each frame-side axis to draw an arc trajectory, the distance between the trajectories is appropriately maintained and the center of the door-side axis is From the closed state to the open state. There are countless such positions, and their selection is easy.

As a result, such a hinge makes it possible for the door to completely follow the wall. For example, even in a normal house, a wheelchair can pass through the frontage when the door is opened.
