The ball retainer 72 has a length that is approximately twice the width dimension of the slide support member 5 in the opening / closing direction, and the ball retainer 72 is fixed to the fixed rail corresponding to the movement of a half of the movement distance of the moving rail 74. It is formed in a substantially one-half of the length of the opening and closing direction of the width dimension of 71.
[0019]
The second slide rail 8 is fixed to the horizontal mounting wall 62 and fixed to the horizontal mounting wall 62 in a transversely substantially C-shaped fixed rail 81, and is slidably disposed on the fixed rail 81 via a ball retainer 82, a ball 83,. The width of the moving rail 84 in the opening / closing direction is approximately twice as long as the width of the sliding support member 5 to which the support fitting 4 is connected. The ball retainer 82 is formed to have a length that is approximately one half of the width dimension in the opening / closing direction of the fixed rail 71 in response to the movement of one half of the movement distance of the moving rail 84. ing.
[0020]
That is, the first slide rail 7 the second slide rail 8 is the same shape, each of the balls 73 ..., because the direction 83 ··· are located has a strength stronger structure does not occur with backlash By integrating the respective moving rails 74 , 84 and the first mounting portion 54 and the second mounting portion 55 of the slide support member 5, the load of the second door 3 is supported by the first slide rail, Even if a load in the front and back direction is generated on the slide support member 5, the second slide rail 8 disposed in the horizontal direction receives the load, so that the second suspended rail 5 is suspended from the slide support member 5 via the support fitting 4. The swing in the front and back direction that occurs when the door 2 is opened and closed is minimized.
In the embodiment, the second slide rail 8 is disposed horizontally, but the direction in which the second door 3 is prevented from shaking in and out, that is, the slide support member 5 is centered on the first slide rail 7. It is more effective if it is provided in a horizontal direction slightly tilted from the horizontal along the rotating direction.
[0021]
The opening / closing auxiliary member 9 is directed to the upper end of the link mounting seat 91 that protrudes upwardly from the upper surface of the central portion in the opening / closing direction of the upper horizontal wall 64 of the fixing member 6 toward the closing side when the folding door 100 is closed. A first link 92 having a first pivot point 901 whose end is pivoted in a substantially horizontal posture, and one end pivoted to the other end of the first link 92, and the other end is the back surface of the slide support member 5. A second link 94 having a second pivot point 902 pivotally supported by a lower link mounting seat 93 provided on the side, and disposed between the first link 92 and the second link 94, The first biasing body 95 (a bow-shaped leaf spring, compression spring, torsion coil spring, etc.) that constantly biases the two links 94 in the opening direction, and between the closed end of the fixing member 6 and the slide support member 5 And always urge the second door in the closing direction, and the first urging body 95 Second urging member is set weaker than the force 96 (constant force spring is desirable.) Is constructed from.
[0022]
Since the opening / closing auxiliary member 9 is configured as described above, in the fully closed position of the second door 3, the second pivot point 902 is located on the closed side of the first pivot point 901, and the first biasing body. 95 always urges the first link 92 and the second link 94 to open, so that the first urging body 95 always urges the second door 3 to maintain the fully closed position, and The 2 biasing bodies 96 also always bias the second door 3 in the direction in which the second door 3 is closed, and the fully closed posture is always maintained.
From this state, when the second door 3 is opened against the urging forces of the first and second urging bodies 95 and 96, the second pivot point 902 is moved to the first position as the slide support member 5 moves. While moving away from the first pivot point 901, the second pivot point 902 is positioned below the first pivot point 901. (State shown in phantom line in FIG. 7).
In this state, the urging force of the first urging body 96 is loaded downward, and when the second urging body 96 is not present, the second door 3 is stopped while being opened.
[0023]
Further, when the second door 3 is opened against the urging force of the second urging body 96, the first urging body starts from the moment when the second pivot point 902 is located on the open side of the first pivot point 901. The urging force 95 is formed stronger than the urging force of the second urging body 96 and is further urged so that the distance between the first pivot stop point 901 and the second pivot stop point 902 is increased. Even if no opening force is applied in the opening direction, the door automatically moves in the opening direction, and the folding door 100 is in the opening posture and the state is maintained.
[0024]
Next, when the second door 3 is closed against the urging force of the first urging body 95 from the open position of the folding door 100, the second pivot point 902 is moved with the movement of the slide support member 5. Moves to the closing side while reducing the distance from the first pivot point 901, and the second pivot point 902 is eventually located below the first pivot point 901. In this state, the urging force of the first urging body 96 is loaded downward, and when the second urging body 96 is not present, the second door 3 is stopped while being opened.
[0025]
Furthermore, when the second door 3 is closed together with the urging force of the second urging body 96, the first urging body 95 is urged from the moment when the second pivot point 902 is located on the closed side of the first pivot point 901. Since the force is biased so that the distance between the first pivot point 901 and the second pivot point 902 is increased, the slide support member 5 exerts a closing force in the closing direction together with the biasing force of the second biasing body 96. Even if it is not loaded, it automatically moves in the closing direction, and the folding door 10 is in the closed posture and the state is maintained.
[0026]
That is, the folding door 100 is automatically closed from the time when the second pivot point 902 is positioned on the closed side of the first pivot point 901, and the second pivot point 902 is opened on the open side of the first pivot point 901. Since the folding door 100 is automatically opened from the time when it is positioned in the position, it is easy to pass by a wheelchair and is easy to use.
In the embodiment, the second urging body 96 is provided. However, the above function is sufficiently exhibited even if the second urging body 96 is not provided.
However, when only the first biasing body 95 is used, when the second door 3 is fully closed, the slide support member 5 hardly moves to the closed side, and the support bracket 4 and the second door 3 are fully closed. Therefore, if the urging force of the first urging body 95 is increased in order to make sure that the first urging body 95 is fully closed, the folding door 100 is suddenly opened in the middle of opening, and an impact sound is generated when fully opened. (There is no particular problem when using it.)
[0027]
If the urging force of the first urging body 95 is weakened to eliminate the impact sound, there is a possibility that the folding door 100 cannot be fully closed automatically when the folding door 100 is closed. In order to increase the degree of perfection, a second biasing body 96 that constantly biases the second door 3 in the closing direction is provided, and the biasing force of the second biasing body 96 is applied to the biasing force of the first biasing body 95. Thus, by automatically closing the folding door 100 and setting the urging force of the second urging body 96 slightly weaker than the urging force of the first urging body 95, the urging force in the opening direction from the middle of opening. To prevent the impact sound that is generated when it is fully opened.
[0028]
In the opening / closing auxiliary member 9 of the embodiment, the first urging body 95 is disposed between the first link 92 and the second link 94, and the second urging body 96 is disposed between the fixing member 6 and the slide support member 5. Basically, the opening / closing auxiliary member 9 has a first pivot point 901 whose one end is pivoted to the fixing member 6 and a second pivot point which is pivoted to the second door 3 side. The second pivot point 902 is located on the closed side of the first pivot point 901 in the closed position of the folding door 100, and the second pivot point 902 is in the middle of opening the folding door 100. The point 902 is provided so as to be positioned on the open side of the first pivot point 901, while the distance between the first pivot point 901 and the second pivot point 902 is always biased in a direction in which the distance is increased. That's fine.
[0029]
That is, instead of the first link 92, the second link 93, and the first biasing body 95, a torsion coil spring or a gas spring is used, with one end at the first pivot point 901 and the other end at the second pivot. The object of the present invention can be achieved even with a structure that pivots to the stop point 902.
Further, in the above embodiment, since a compression spring is used for the first biasing body 95, one end of the mandrel is connected to the second link 94 in order to prevent the compression spring from becoming arcuate when the second door 3 is moved. However, the other end may be disposed in the compression spring so as to be rotatable and slidable on the first link 92.
[0030]
In the rammer panel 10, an upward locking protrusion (not shown) formed at the upper end is locked inside the upper frame 12 of the three-sided frame 1, and both opening and closing side ends are the inner surfaces of the opening and closing side vertical frames 11 and 11. On the side, it is detachably mounted by screwing to a luma mounting seat (not shown) that protrudes in the opening / closing direction.
[0031]
