Description

  The present invention relates to a sliding door device that can be easily held and opened and closed when a person with reduced mobility opens and closes the sliding door.

  FIG. 10 shows a conventional general sliding door (A), and a handle (H) is attached to the door end side of the sliding door (A). The shape of the handle (chi) is generally U-shaped, and the grip portion (re) extends in the vertical direction at a position separated from the sliding door surface by a certain space. A person can grasp the appropriate position of the grip (re) and pull the sliding door (a) to open. And if it is a semi-automatic sliding door device, the opened sliding door (I) can be closed alone.

  By the way, high-precision aluminum upper rails are used in recent sliding door devices, resin materials such as polyacetal having excellent wear resistance are used for the rollers of suspension cars, and high-performance radial bearings are built in. The door can be opened and closed with a light force of about 1 kg. However, it is not easy for an elderly person or a handicapped person to open and close the sliding door by holding the handle (chi). In particular, the operation of opening and closing the sliding door is difficult for a physically handicapped person in a wheelchair.

FIG. 11 shows a case where a conventional sliding door (A) having a generally U-shaped handle (H) is opened. In the figure, the person operating is a disabled person (nu) and is in a wheelchair (le).
In (a), a disabled person (nu) in a wheelchair (le) can pull the sliding door (ii) by grasping the handle (chi). In this case, the sliding door (ii) is about 1 / Up to about 2 can be opened. That is, it is possible to pull the handle (chi) to the dotted line position with the grip (re).

  Therefore, after that, as shown in (b), the wheelchair (le) must be retracted and pulled again as shown in (c). From the fully open entrance (e) to (d) You will enter the wheelchair. As described above, in the sliding door (A) provided with the generally U-shaped handle (H) shown in FIG. 10, the wheelchair (LE) must be moved backward when the sliding door (A) is pulled about 1/2. Therefore, going in and out is troublesome and takes time.

  In addition, as shown in FIG. 12, if a sliding door (I) is provided at the corner of the room, the disabled person (N) on the wheelchair (LE) The problem that the hand is out of reach occurs. That is, the tip of the wheelchair (le) hits the wall surface, and the wheelchair (le) cannot be moved forward. Therefore, it is necessary to get out of the wheelchair (le) and grasp the handle (chi), which may cause the balance of the body to be lost, which is very dangerous.

Therefore, the applicant has developed a sliding door equipped with a handle that can easily open and close the sliding door even if it is a physically handicapped person in a wheelchair. Japanese Patent Application Laid-Open No. 2006-152633 discloses a “sliding door handle and a sliding door provided with the handle” provided with a main grip portion extending in the vertical direction parallel to the sliding door surface on the door tip side, and the door with respect to the main grip portion. An auxiliary grip portion extending in the vertical direction is provided in parallel on the bottom side. Therefore, the sliding door can be fully opened by changing to the main gripping portion when the auxiliary gripping portion is first opened by about ½.
"Sliding door handle and sliding door provided with the handle" according to JP-A-2006-152633

  Thus, by devising the shape of the handle, it becomes easy for the handicapped person who is on the wheelchair to open and close the sliding door. However, some people with physical disabilities cannot hold the handle firmly because their hands are inconvenient. Even if the shape of the handle is devised, there is no meaning for a seriously disabled person. The problem to be solved by the present invention is this problem, and provides a sliding door device that can be opened and closed safely without firmly grasping the handle.

  The handle for a sliding door according to the present invention has a generally rectangular shape with a curved corner portion, and has a main grip portion extending in the vertical direction on the door end side and an auxiliary grip portion extending in the vertical direction on the door bottom side. The upper end of the auxiliary grip is connected by an upper grip that extends horizontally, and the lower end of the main grip and the auxiliary grip is connected by a lower grip that extends horizontally. And the arm is provided in the upper-lower-end part located in the main grip part side of this handle | steering-wheel, and it attaches to a sliding door via this arm.

  The main grip portion is formed to extend in a vertical direction leaving a predetermined space from the sliding door surface, and the auxiliary grip portion is also parallel to the sliding door surface. In the present invention, a large space is provided between the handle and the panel surface of the sliding door. A handicapped person can place a fist between the auxiliary grip and the panel surface, lock the fist on the auxiliary grip and pull the sliding door, and when the sliding door opens and is stored in the door pocket In addition, the space is such that the fist does not get caught between the door pocket panel and the sliding door frame standing at the door entrance.

  In the present invention, the size of the space is set to 50 mm or more. Here, the sliding door device has a type having a door pocket, and a type having a door pocket panel only on one side, but the door pocket panel or the sliding door frame and handle in a state where the sliding door faces the door pocket panel opened. The space formed between the auxiliary grip portion is set to 50 mm or more.

  Since the handle of the present invention comprises a main grip part, an auxiliary grip part, and a general rectangle composed of an upper grip part and a lower grip part, a physically handicapped person who rides on a wheelchair does not move the position of the wheelchair, At first, the sliding door can be opened to some extent with the auxiliary gripping portion, and then the sliding door can be opened by changing to the main gripping portion. Therefore, the sliding door can be fully opened easily without moving the wheelchair and can be quickly entered from the entrance.

  Even when a sliding door is installed in the corner of the room, it is possible to pull the sliding door by grasping the auxiliary gripping portion without riding out in a state of riding in a wheelchair. An elderly person who walks with a cane can open by placing a hand on the upper grip portion of the generally rectangular handle, and each person can hold an appropriate part of the handle. Further, since the auxiliary grip portion of the handle forms a space of 50 mm or more between the door pocket panel surface and the sliding door frame, a hand can be put into this space. Therefore, even if the auxiliary grip portion is not firmly gripped, the sliding door can be opened by hooking the fist on the auxiliary grip portion, and at this time, the hand is not caught between the door pocket panel and the sliding door frame.

  FIG. 1 is an embodiment showing a sliding door 1 according to the present invention. The sliding door 1 is composed of a vertically long rectangular panel. A suspension car (not shown) is attached to both sides of the upper end, and the sliding door 1 is suspended from an upper rail (not shown) via the suspension car. A handle 2 is attached to both sides or one side of the sliding door 1, and a person can hold the handle 2 to open the sliding door 1.
