FIG. 1: is the front view (a) and side view (b) of a door by one Embodiment (Example 1) of this invention, FIG. 2 is the principal part expanded side view. As shown in the figure, the door-end side panel 2 and the door-end side panel 3 each formed in a rectangular shape in plan view are configured as a folding door 1 in which the connecting member 4 is rotatably connected (openable and closable). In the door, an upper handle 5 and a lower handle 6 for opening and closing operations are respectively attached to both side surfaces near the non-connected end (closed side end) of the door-end side panel 2. Although not shown, the folding door 1 is installed on an opening frame configured as a three-way frame including an upper frame and left and right vertical frames on the floor surface, and the door-end side panel 2 is a left vertical frame of the opening frame. The upper end on the side is suspended from the upper frame, and the door-side panel 3 is suspended from the upper frame at the upper end on the right vertical frame side. The connecting member 4 that connects the door-end side panel 2 and the door-end side panel 3, the suspension means for suspending the door-end side panel 2 and the door-end side panel 3 on the upper frame, and the like are well-known, and Since it is not directly related to the subject matter of the present invention, detailed description is omitted.

The upper handle 5 is provided at the same height position as the handle provided on the conventional door, that is, approximately at the center in the height direction of the door 1 so that an adult can easily stand and operate. On the other hand, the lower handle 6 is provided near the floor surface, preferably at a height position where at least a lower end portion 64 of the lower handle 6 hits a foot support (footrest) of the wheelchair.

The upper handle 5 includes a handle member 51 and a fixing member 52 that fixes the handle member 51 to the door. The lower handle 6 has the same configuration, and includes a handle member 61 and a fixing member 62 that fixes the handle member 61 to the door. In this embodiment, fixing portions (upper end portions 53, 63) are provided at the upper ends of the handle members 51, 61 to fix the handle members 51, 61 to both side surfaces of the door-end side panel 2 of the folding door 1, and the fixing portions. Is curved away from the panel surface to ensure the rotation stroke of the grip members 51 and 61.

When both the upper handle 5 and the lower handle 6 are pushed so as to approach the panel surface, the latch 7 provided on the closed end of the door-end side panel 2 is released to open the door. It is configured as a push lever type handle. Further, the latch of the door can be released even when either the upper handle 5 or the lower handle 6 is pushed.

An example of the latch release means for releasing the latch by pushing the upper handle 5 or the lower handle 6 is shown in FIG. As is well known, the latch 7 is always biased in a protruding direction by a biasing means (not shown) provided in the latch mechanism 8, and when the door-end side panel 2 is in a closed state, In the left vertical frame, the door engaging side panel 2 is maintained in a closed state by engaging with a latch engaging recess (not shown) formed at a corresponding height position. A latch releasing means is provided so that the latch 7 can be released by pushing either the lower handle 6 or the lower handle 6. Hereinafter, the latch mechanism 8 and the latch release means will be described with reference to FIG.

FIG. 3 is an exploded side view (a) and an attached side view (b) showing the handle structure. The handle structure is common to the upper handle 5 and the lower handle 6, and the structure of the upper handle 5 is shown in FIG. In the handle member 51, a fitting piece 55 is integrally formed on the inner surface side of the upper end portion 53, and a latch operation rod 56 protrudes from the fitting piece 55. The fitting piece 55 is accommodated in the fitting hole 57 of the fixing member 52 fixed to the panel surface near the closed side end of the door-end side panel 2 at a predetermined height position, and is pinned in the pin holes 58 (58a, 58b). (Not shown) is attached so that a slight rotation is allowed in the fitting hole 57 around the pin. In this attached state, the latch operation bar 56 passes through the fitting hole 57 of the fixing member 52 and protrudes into the thickness of the door-end side panel 2. On the latch mechanism fitting portion 56a, a moving member 81 that can move up and down within the panel thickness is placed. In such a configuration, when the handle member 51 of the handle 5 is pushed, the fitting piece 55 fitted in the fitting recess 57 rotates about the pins (pin holes 58a, 58b) in the clockwise direction in the drawing, so that the latch release is performed. The moving member 81 placed on the latch mechanism fitting portion 56a on the upper surface of the latch operation rod 56 serving as means is moved upward. In such a configuration, when the handle member 51 of the upper handle 5 is pushed toward the panel surface, the fitting piece 55 fitted in the fitting hole 57 is clockwise in the drawing with the pins (pin holes 58a, 58b) as the center. Since it rotates, the latch operation rod 56 moves upward, and the biasing means of the latch mechanism 8 is loosened via the moving member 81 of the latch mechanism 8 placed on the latch mechanism fitting portion 56a on the upper surface thereof. The latch 7 is released from the latch engaging recess. Thereby, the door-end side panel 2 can be opened via the connecting member 4. Such latch mechanism 8 and latch release means are well known and are not directly related to the subject matter of the present invention, and therefore will not be described in detail. Further, another latch mechanism / latch release means may be employed.

Although the structure of the lower handle 6 is not shown, it is the same as the structure of the upper handle 5 shown in FIG. 3, and the reference numerals of the respective parts are the reference numerals 10 assigned to the respective parts of the upper handle 5 shown in FIG. The number of the place is changed from “6” to “5”. That is, the sign of the handle member of the lower handle 6 is 61, and its upper end 63 is fixed to the panel surface near the closed side end of the door-end side panel 2 via the fixing member 52 at a position near the floor surface. The latch mechanism 8 is rotated about the pin inserted into the pin hole 68 (68a, 68b) when it is pushed toward the surface, and is rotated in the clockwise direction in the figure and placed on the latch mechanism fitting portion 66a of the latch operation rod 66. The moving member 82 is moved upward.

Referring to FIG. 4, when the latch operating rod 56 moves upward as described above, the latch 7 is released from the latch engaging recess via the known latch mechanism 8, and the door tip is connected via the connecting member 4. The side panel 2 can be opened. Although this series of operations has been described as being executed when the upper handle 5 is pushed, the moving member 81 moved by the latch operation bar 56 of the upper handle 5 and the latch operation bar 66 of the lower handle 6. The moving member 82 that moves is connected to the tip of the moving member 82 via pins 83 and 84 and a connecting member 85. Therefore, when the lower handle 6 is pushed and the moving member 82 moves upward, the moving member 81 also moves upward via these, the latch 7 is released, and the door can be opened. When the connecting member 85 moves up and down, the moving members 81 and 82 connected to the upper and lower ends of the connecting member 85 rotate relative to the connecting member 85, so that the movement at the time of interlocking is made smooth. Therefore, the moving members 81 and 82 are rotatably connected to the upper and lower ends of the connecting member 85 by pins 83 and 84, respectively.

According to this configuration, the handle member 51 of the upper handle 5 is installed at a height position where an adult can easily stand and operate the handle, and the handle member 61 of the lower handle 6 has a lower end 64 close to the floor surface, preferably It extends to the position where the foot support (footrest) of the wheelchair hits, and when the upper handle 5 is pushed, the latch is released directly, and when the lower handle 6 is pushed, the latch is released via the above-mentioned interlocking mechanism. It is formed to be able to. Moreover, since both the handles 5 and 6 are push lever types, they can be opened by pushing with a part of the body or with a wheelchair. Therefore, it can be opened easily not only by healthy people but also by short children and wheelchair users, and especially for wheelchair users who are handicapped, they can perform any operation to open the door. Instead, by moving forward with the wheelchair, the handle member lower end portion 64 of the lower handle 6 can be pushed and opened by the foot support (footrest) of the wheelchair.

The connecting member in the latch releasing means for releasing the latch by pushing the upper handle 5 or the lower handle 6 is a plate-like or rod-like rigid member (wood, metal, hard synthetic resin as shown in FIG. 4 as the connecting member 85). May be used instead of a wire-like or belt-like connecting member 86 as shown in FIG. According to this configuration, the moving member 81 and the moving member 82 are connected by the wire-shaped or belt-shaped connecting member 86 capable of traveling on the predetermined traveling path defined by the pulleys 87 (87a to 87d), and the lower handle When the moving member 82 is moved upward by pushing 6, the moving member 81 is also simultaneously moved upward via the connecting member 86, so that the latch 7 is released. As shown in FIG. 5B, the connecting member 86 and the pulley 87 may be embedded and fixed from the closed side end of the door-end side panel 2 in a unit that is previously accommodated in the case 88. Since the configuration excluding the connecting member and the members related thereto is the same as that shown in FIG. 4, the description thereof is omitted.

Although the latch release means has been described with reference to FIGS. 4 and 5, the latch release means is not limited to these, and the latch 7 can be engaged even when either the upper handle 5 or the lower handle 6 is pressed. Other configurations may be adopted as long as they can be released. Various interlocking mechanisms that interlock the movements of the two members have been proposed, and any one of them can be arbitrarily selected and employed in the present invention.

FIG. 6 is a side view of an attached state showing another example of a handle shape that can be employed in the door of the present invention and a preferred fixing mode thereof, but the basic configuration is the same as the handles 5 and 6 in the embodiment described above. The same or corresponding members / elements are denoted by the same reference numerals, and descriptions thereof are omitted. The difference from the above-described embodiment is the shape and configuration of the handles 5 and 6. In the above-described embodiment, the portions of the handle members 51 and 616 that are directed downward from the fixing portions (upper end portions 53 and 63) are separated from the panel surface. In the embodiment shown in FIG. 6, the grip members 51 and 61 are formed so as to extend linearly, while the rotation strokes of the handle members 51 and 61 are secured. . In this case, in order to ensure a stroke in which the handle members 51 and 61 rotate during the opening operation, the fitting pieces 55 and 65 and the fixing members 52 and 62 are slightly lengthened to form the linear handle member 51. , 61 and the panel surface are provided with a certain distance.
