As shown in FIG. 4, the weight member 18 is formed by fixing weights 19 on both sides of an elongated plate-shaped body 18a, and running wheels 20 are provided at both front and rear ends of the plate-shaped body, and the weight members 18 are fallen on both sides. A roller 21 is provided for holding the roller 21 in such a manner that it does not move. The traveling wheel 20 rides on the sliding door guide rail section 16 as shown in FIG. 2, and the roller 21 is in rolling contact with the inner surface of the weight guide rail 15. Therefore, when the weight guide rail 15 is inclined, the weight member 18 is movable along the longitudinal direction of the weight guide rail 15 according to the inclination. The weight guide rail 15 is horizontal if the weights on both sides are balanced with the support shaft 14 interposed therebetween. However, the fulcrum is slightly moved toward the sliding door side when the fulcrum is opened, and the weight guide rail 15 It is set so as to swing in the direction of a downward slope toward the closing side. The balance may be adjusted by changing the weight of the weight member 18 or the position of the support fitting 13.

Next, the weight member 18 and the sliding door 2 are connected via a connecting arm 22. The connecting arm 22 is set obliquely so as to correspond to a change in the distance between the weight member 18 and the sliding door 2.

According to the above configuration, after the sliding door 2 is opened along the sliding door rail 5 (the state shown in FIG. 1) and the force is released, the weight guide rail 15 is inclined downward toward the closing side of the sliding door 2 (see FIG. 1). 1 (indicated by a dotted line in FIG. 1), the weight member 18 moves in the closing direction of the sliding door 2. Since the sliding door 2 is connected to the weight member 18 via the connecting arm 22, the sliding door 2 also moves in the closing direction together with the weight member 18 and automatically closes.

Next, an operating rod 24 is connected to an end of the weight guide rail 15 via a connecting rod 23. The operating rod 24 is provided along the vertical frame 1b of the opening edge frame 1, and is arranged so as to be vertically movable from outside. As shown in FIG. 5, a concave groove 25 is formed in the longitudinal direction of the inner surface of the vertical frame 1b, and an operating rod housing frame 26 is fixed on the concave groove 25. The operating rod housing frame 26 includes a housing frame main body 26a fixed to the recessed groove 25 with screws and a housing frame cover 26b detachable from the operating rod housing frame 26, and a hollow portion for housing the operating rod 24 therein. 27 are formed. A decorative frame 26a corresponding to the housing frame cover 26 is attached to the opposite vertical frame 1b. A bellows-shaped buffer member 10 (see FIGS. 1 and 3) is provided at the free end of the connecting rod 23.

An operating handle 28 (operating means) shown in FIGS. 6 to 8 is provided movably in the vertical direction along the housing frame 26 at a position slightly lower than the middle of the housing frame main body 26a. The handle 28 is formed by connecting two left and right handle members 28a by a connecting plate 28b. As shown in FIG. 7, a notch 29 corresponding to the moving range of the handle 28 is formed in the housing frame cover 26b, and the handle 28 is stored so as to be able to move inside the notch 29. A pair of left and right guide rollers 30 are provided above and below the handle 28, respectively, and each guide roller 30 is arranged to be rollable along both side edges 31 of the housing frame main body 26a. In addition, a locking piece 32 whose tip protrudes downward is provided inside the handle 28. On the other hand, when the operating rod 24 reaches the lower moving end, the locking bracket 33 is locked to the locking piece 32 on the housing frame body 26a.
Has been fixed.

The operating rod 24 is connected to a handle 28 via a pulley mechanism. That is, the fixing bracket 38 on the upper part of the handle 28 and the operating rod 24 are connected via the rope 34. The rope 34 is hung on a pulley 35 (see FIGS. 5 and 6) which is fixed in the housing frame 26. A guide roller 36 is attached to the lower end of the operating rod 24. Correspondingly, a stopper 37 that can be engaged with the guide roller 36 at a lower moving end is fixed to the housing frame 26.

In the above configuration, the handle 28 is
9, the guide roller 30 is lowered while rolling along the housing frame main body 26a as shown in FIG. 9, but since the rope 34 is suspended by the pulley 35, the operating rod 24 moves upward. I do. Thereby, one end of the weight guide rail 15 rises as shown in FIG. 1 and swings so as to have a downward slope toward the opening side of the sliding door 2.
Moves according to the above gradient. Since the sliding door 2 is connected to the weight member 18 via the connecting arm 22, the sliding door 2 moves in the opening direction together with the weight member 18, and the sliding door 2 is opened. When the handle 28 is moved to the lowermost end, the locking pieces 32 are locked by the locking hardware 33, and the open state of the sliding door 2 is maintained. The locking mechanism employs a known mechanism, and is configured to be in a holding state when the locking piece 32 is pressed against the locking bracket 33, and to be in a released state when a force is again applied in the pressing direction.

When the locking piece 32 and the locking fitting 33 are released, the weight guide rail 15 swings so as to naturally descend toward the closing side of the sliding door 2 due to the weight balance on both sides of the support shaft 14. (See the dotted line in FIG. 1). For this reason, the sliding door 2 automatically closes and operates together with the weight member 18. At the same time, the handle 28 returns upward. The weight member 18
The end of hits the cushioning member 10 at the moving end at the time of opening and closing, and the shock is reduced. The guide roller 36 at the lower end of the operating rod 24 engages with the stopper 37 at the lower moving end as shown in FIG.

As described above, the sliding door 2 can be automatically closed without directly touching the sliding door 2.
Since it is easier to lower the operation of 8 than to raise it, the operability is particularly excellent when operating from a wheelchair.

The above-mentioned opening / closing mechanism has a construction in which the sliding door 2 automatically closes after the opening operation. On the contrary, the sliding door 2 is automatically opened and operated only when the sliding door is closed. You may.

Alternatively, the support bracket 13 may be arranged at the center of the sliding door rail 5 so that the weight guide rail 15 is balanced, and the opening and closing operations may be performed at the time of opening and closing.

Further, the operating rod 24 and the handle 28 need only be connected via a pulley mechanism, and are not limited to the above-mentioned constant pulley mechanism. For example, as shown in FIG. 26, and may be connected to a moving pulley 39 fixed to the lower end of the operating rod 24 via a moving pulley mechanism wound around a constant pulley of the housing frame 26.

Further, in the above embodiment, the single sliding door type sliding door is shown, but the arrangement of the sliding door is not limited to this.

Of course, a sliding door (not shown) is used for the sliding door 2.
And the sliding door 2 may be opened and closed directly.
