  In this case, since the carriage and the partition are the same length in the width direction, it is assumed that the sliding door gate secured its independence and opening / closing stability by supporting the carriage so that the entire width of the sliding door gate is placed. However, in order to open a closed sliding door on the back side, it is necessary to place a hand on a tilting pole from the back side of the partition, avoiding the trolley at the door end, so that the forward bending is unstable. It is necessary to push the sliding door to the door pocket side, and in order to close the opened sliding door, avoid the carriage so that the foot does not hit the carriage, and similarly put the holding column in the forward bent state. It is necessary to draw it toward the side, and the opening and closing operation is unstable and tends to be complicated. Since sliding doors are generally formed as heavy objects, it is often necessary to apply force to open and close the side doors, and when closed, there is a danger that the carriage will be stepped on when opening and closing due to inertia acting on the sliding doors. For a wheelchair user without helping a person, the sliding door can be pushed and pulled by placing the hand on the sloping pole while the wheelchair user is sitting on the wheelchair. It is virtually impossible to open and close the gate.

  The present invention has been made in view of such circumstances, and the problem to be solved is that a wheelchair user can independently open and close the door horizontally so that the door can be safely and easily accessed. The purpose is to provide sliding doors that can be opened and closed independently.

  In accordance with the above-described problems, the present invention is a cantilever with a width of about a fraction of the width of the sliding gate door facing the door tip side, for example, by the wide sliding door gate formed as a heavy object. Even if the trolley and holding column on the door end side are not installed so as to protrude, if the trolley and holding column are installed in the remaining width, which is still wide, the independence of the sliding door gate and the stability of opening and closing are impaired. Focusing on the fact that there is no possibility that it will be broken, by placing a wheelchair entry space that can approach the back of the front door of the sliding door, without a carriage and a holding post on the back of the sliding door gate, A wheelchair user enters the wheelchair entry space, and closes and pulls the handle safely and easily in a stable position close to the handle installed on the front frame of the front partition. When you can open and close In addition, the front and rear rails on which the carriage travels in the wheelchair entry space are made non-existent. On the other hand, the above-mentioned handle is arranged in the middle of the front and rear sides of the door frame. In addition, the width of the wheelchair access space is arranged so as not to impair the independence of the sliding door and the stability of opening and closing. A sliding door gate that allows a wheelchair user to open and close independently by operating a pull handle installed in the vertical frame on the door side for opening and closing, a front frame, a rear frame, and a plurality of The frame is shortened by the length of the frame extension by installing a frame extension having a cross frame and extending in series on the front frame toward the door end. A carriage that moves on a pair of front and rear rails by a roller installed on the front frame and the rear frame, with a cross frame on the door-end side disposed between the front end of the rear frame and the middle in the width direction of the front frame; The front frame has the same length as the front frame standing and fixed over the entire length of the front frame as a lower frame, and includes the front end of the rear frame and the intermediate position in the width direction of the front partition. A holding column fixed between the rear frame and the vertical frame arranged on the front partition, and on the door frame side of the door frame side and the door side of the locking column and on the back of the frame extension of the front partition A wheelchair entry space having a flat L-shape is formed for lateral opening and closing by wheelchair entry, and the width of the wheelchair entry space from the door-side vertical frame is about 1 m of 0.8 m or more. On the other hand, when the sliding door gate is closed, the pair of front and rear rails are installed from the position of the roller on the door side to the door pocket side when the sliding door is closed, and the pair of front and rear rails are not placed below the wheelchair entry space. It is a sliding door gate for wheelchair users to open / close independently, characterized in that it is installed in the upper and lower middle positions with the handle for opening / closing operation of the wheelchair user on both front and back sides of the vertical frame on the door side. Is a means for solving the above problems as a gist of the invention.

  Since the present invention is configured as described above, by disposing a wheelchair entry space that can approach the back of the front door of the sliding door, with no carriage and holding column installed on the back of the door front side of the sliding door. , A wheelchair user enters the wheelchair entry space, and closes and pulls the handle safely and easily in a stable position close to the handle installed on the vertical frame on the door side of the front partition. The front and rear rails where the carriage travels in the wheelchair entry space are made non-existent, and the handle is arranged at the upper and lower middle positions on both the front and rear sides of the door frame. It is possible to open and close both sides of the sliding door gate of the user alone, and to impair the independence of the sliding door and the stability of opening and closing, even if the width of the wheelchair access space is arranged. It is possible to provide sliding doors gates of wheelchair users alone open and out for that as no.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a sliding door that allows a wheelchair user to open and close independently by operating a handle installed in a door-side vertical frame for opening and closing the wheelchair user. The sliding door A includes a front frame 21, a rear frame 23, and a plurality of cross frames 24 disposed therebetween, and a frame extension portion 22 that extends in series to the front frame 21 toward the door end side. The rear frame 23 is shortened by the length of the frame extension 22, and the door-side crossing frame between the shortened rear-frame-side front end of the rear frame 23 and the middle of the front frame in the width direction is installed. 24, a carriage 2 that runs on a pair of front and rear rails 1 by rollers 3 installed on the front frame 21 and the rear frame 23; A series of front partition bodies 4 having the same length as the front frame 21 standing and fixed over the entire length thereof, the rear frame 23 including the front end of the rear frame 23 and the intermediate position in the width direction of the front partition body 4 A holding column 45 fixed between the vertical frame 42 arranged on the front partition 4 and a door extension side of the door frame side and the door column side surface of the holding column 45 and a frame extension of the front partition 4 A wheelchair entry space 5 having a flat L-shape is formed on the back surface of the wheelchair 22 for lateral opening and closing by wheelchair entry, and the width from the door-side vertical frame 42 in the wheelchair entry space 5 is 1 m of 0.8 m or more. On the other hand, when the sliding door gate is closed, the pair of front and rear rails are installed from the position of the roller 3 on the door side to the door pocket side when the sliding door is closed, and the pair of front and rear rails 1 are placed in the wheelchair entry space. And the absence in the lower of the scan 5 and is as that with the tab 43 for opening and closing operation of the wheelchair users around both sides of the door end side vertical frame 42 is placed in the vertical middle position. At this time, the sliding door A is configured such that the carriage 2 is made of steel, and the front partition 4 and the holding pillar 45 are made of aluminum, respectively. For example, the sliding door A is installed at a wide doorway in a public facility or factory.

  The pair of front and rear rails 1 are made of, for example, inverted L-shaped steel and are embedded in the ground surface so that the upper rail surface is substantially level with the ground surface, and the carriage 2 intersects with the front and rear frames 21 and 23. The rollers 3 are framed by the rollers 24, and the rollers 3 installed downward at a plurality of longitudinal positions of the front and rear frames 21 and 23 of the carriage 2 are placed on the rail surfaces of the pair of front and rear rails 1 to cover the rollers 3. Thus, the L-shaped guide plate 31 installed so as to face the front and rear is hooked and engaged with each rail, particularly the lower surface of the rail surface, and the front and rear guide plates 31 hold the pair of front and rear rails 1 from the outside. By holding it, the roller 3 of the carriage 2 can travel stably on the rail 1 without being derailed.

  The front partition 4 is erected and fixed on the front frame 21 of the carriage 2 so as to form a vertical partition surface so as to serve as a lower frame. For example, the long upper frame 41, both ends in the width direction, A grid partition comprising a plurality of intermediate vertical frames 42 and a number of vertical bars 44 arranged between the vertical frames 42 with the upper and lower ends fixed to the upper frame 41 and the front frame 21, In the example, the front partition 4 is provided with a handle 43 on which the wheelchair user performs the opening / closing operation, respectively, at the door-end side vertical frame 42, particularly at an intermediate position between the front and rear surfaces.

  The holding column 45 is fixed, for example, in an inverted shape, so as to steeply incline upward from the carriage 2 and gently incline from the rear frame 23 of the carriage 2 to the intermediate vertical frame 42 in the front partition 4. For example, the inclination angle from the carriage 2 is about 70 to 80 degrees.

  At this time, the carriage 2 and the holding pillar 45 are arranged from the intermediate position in the width direction near the door side excluding the door edge part of the sliding door A to the door side, and the door part of the front partition 4 is arranged. A wheelchair entry space 5 for wheelchair entry is formed on the back of the front part 4 of the front partition 4 by floating and supporting in a cantilevered manner. At this time, the wheelchair entry space 5 is provided on the door end side. The width from the vertical frame 42 is 90 ± 10 cm.

  In other words, the wheelchair entry space 5 in this example is about 80 cm, for example, so as to have the preferred minimum width dimension. For this reason, the carriage 2 is directed in the 80 cm width direction from the position of the front side frame 42 of the front partition 4. It is arranged toward the door pocket side so as to have the same width as the remaining width of the front partition 4 from the intermediate position in the width direction close to the door tip side toward the door pocket side. 21 is provided with a frame extension 22 having the same length as the front partition 4 for mounting the front partition 4, and the rear frame 23 is made shorter than this, and the intersection frame 24 closest to the door-end is formed at the tip of the rear frame 23. Is arranged so as to be bridged between the front frame 21 and the end of the carriage 2 is closed, and the door post 43 on the most end side is located on the cross frame 24 of the carriage 2. Like the cart 2 and forward It is placed between the door leading end side vertical frame 42 of Setsutai 4.

  Further, at this time, the pair of front and rear rails 1 in this example are installed from the position of the roller 3 on the side of the door installed on the carriage 2 to the door pocket side when the sliding door A is closed, thereby partially The rail 1 is not present below the open space 5 so that the floor surface of the portion continuously forms a flat surface.

  The sliding door A for single wheelchair user opening / closing, formed as described above, has a rear end of the door tip portion, that is, a cross frame 24 at the front end of the door tip side and a door tip side surface of the holding column 45 and a frame extension portion. Since the wheelchair access space 5 without the carriage 2 and the holding post 45 is formed on the back of the front partition 4 on 22, a flower bed, hedge, fence, fence, etc. are installed on the door side with a single-drawer Even when the wheelchair is in the wheelchair access space 5, the user pulls in the wheelchair entrance space 5, approaches the puller 43 of the door-end side vertical frame 42, and performs the horizontal pulling operation of the sliding door A in a stable posture safely and easily. In the case of double pulling, the wheelchair entry space 5 having a double width is formed between the sliding doors A, so that the opening / closing operation can be performed more easily. In addition, a cantilever-like floating support portion corresponding to the width of the wheelchair entry space of 5 widths is formed on the door end side of the sliding door A, but the sliding door A itself is wide as a heavy object. The floating support portion does not impair the independence of the sliding door A and the stability of opening and closing. Furthermore, in this example, when there is no rail 1 in the wheelchair entry space 5 as described above, the rail 1 becomes a wheelchair passage obstacle when the sliding door A is opened and opened at the door tip. The possibility can be eliminated.

  The illustrated example is as described above, but a specific pair of front and rear rails, sliding door gates, its bogie, front partition, holding column, wheelchair entry space, specific shape, structure, material, width dimension, relationship between these, Additions to can be made in various forms as long as they do not contradict the gist of the invention.

It is a front view of a sliding door. It is a longitudinal cross-sectional view of a sliding door. It is a top view of a sliding door. It is a bottom view of the cart part of a sliding door gate.
