[Stopper member 60]
FIG. 7 is a perspective view of the stopper member 60. FIG.
The stopper member (contact member) 60 has a stopper main body 61 and a pair of guide portions 62 . As shown in FIG. 5, the stopper member 60 is attached to the edge of the door body 20 inside the recessed groove 21 of the door body 20 . The stopper member 60 is made of an elastic member such as hard rubber. When the door body 20 moves to the open state, the stopper member 60 contacts the lower guide 40, decelerates the door body 20, and stops the door body 20 in the open state.

FIG. 8 is a front view of the stopper member 60 attached to the recessed groove 21. FIG.
The stopper main body 61 is formed in a substantially rectangular parallelepiped shape having a cavity inside. The stopper body 61 is arranged in the recessed groove 21 so as to be in contact with the end surface of the door tip side end portion, the bottom surface 21a, the right side surface 21b, and the left side surface 21c. A through hole 61h penetrating from an internal cavity is formed in the upper surface 61a of the stopper body 61 and the rear surface 61b, which is the surface in contact with the end surface of the end portion on the side of the door. The stopper main body 61 is attached to the door main body 20 with a bolt B passing through the through hole 61h.

As shown in FIG. 7, the stopper body 61 has a contact surface 61s with which the roller 43 contacts on a front surface 61c opposite to the back surface 61b. The abutment surface 61s has a curved surface shape in which the central portion of the abutment surface 61s is recessed toward the back surface 61b when viewed from the top surface 61a, and the outer peripheral surface 43a of the contacting roller 43 abuts thereon with almost no gap.

A pair of guide portions 62 (a guide portion 62A and a guide portion 62B) are formed in an elongated shape extending in the extension direction E from the stopper main body 61. As shown in FIG. The guide portion 62A and the guide portion 62B are arranged in the radial direction R, and a path 63 through which the base shaft portion 42 of the roller 43 passes is formed between the guide portion 62A and the guide portion 62B.

As shown in FIGS. 7 and 8, the guide portion 62A and the guide portion 62B are formed substantially line symmetrical with the path 63 interposed therebetween. The side surface of the guide portion 62A opposite to the path 63 is in contact with the right side surface 21b of the recessed groove 21. As shown in FIG. The side surface of the guide portion 62B opposite to the path 63 is in contact with the left side surface 21c of the recessed groove 21. As shown in FIG.

Each of the guide portion 62A and the guide portion 62B has a tip portion 62a, a guide portion 62b, a resistance applying portion 62c, and a contact portion 62d. The tip portion 62a, the guide portion 62b, the resistance applying portion 62c, and the contact portion 62d are formed continuously toward the stopper main body 61, and are formed such that the width in the radial direction R gradually increases. ing.

The distal end portion 62a is arranged at the distal end of the guide portion 62A and the guide portion 62B, and contacts the right side surface 21b and the left side surface 21c of the recessed groove 21 to generate frictional force. When the base shaft portion 42 of the roller 43 passes through the path 63, the tip portion 62a suppresses large movement of the guide portions 62A and 62B due to frictional force.

The guide portion 62b has an inclined surface 62f whose width in the radial direction R gradually increases toward the stopper body 61. As shown in FIG. The guide portion 62 b guides the base shaft portion 42 by the inclined surface 62 f so that the central axis C of the base shaft portion 42 approaches the center of the path 63 when the base shaft portion 42 passes through the path 63 .

FIG. 9 is a cross-sectional view of the pair of guide portions 62 when the rollers 43 pass.
The resistance imparting portion 62c imparts resistance to relative movement of the base shaft portion 42 with respect to the extension direction E. As shown in FIG. When the base shaft portion 42 passes through the path 63 , the resistance applying portion 62 c contacts the base shaft portion 42 and decelerates the base shaft portion 42 . The length in the radial direction R between the resistance applying portion 62c of the guide portion 62A and the resistance applying portion 62c of the guide portion 62B is shorter than the radial dimension of the base shaft portion . Therefore, as shown in FIG. 9, when the base shaft portion 42 passes between the resistance applying portions 62c, the resistance applying portions 62c are elastically deformed in the radial direction R. As shown in FIG. As a result, the resistance applying portion 62c suppresses the relative movement in the extending direction E of the base shaft portion 42 by the restoring force in the radial direction R.

When the base shaft portion 42 passes through the path 63, the rollers 43 are arranged at positions that do not contact the pair of guide portions 62, as shown in FIG. Therefore, even when the base shaft portion 42 passes through the path 63, if the outer peripheral surface 43a of the roller 43 and the right side surface 21b and the left side surface 21c of the recessed groove 21 come into contact with each other, the roller 43 rotates, causing the roller 43 to rotate. and the recessed groove 21 are suitably reduced.

The contact portion 62d defines a relative movement range of the base shaft portion 42 with respect to the extension direction E. As shown in FIG. The contact portion 62d has a curved shape with which the outer peripheral surface of the base shaft portion 42 contacts with almost no gap. The base shaft portion 42 in contact with the contact portion 62d cannot move further toward the stopper main body 61 side.

[Operation of door device 1]
Next, the operation of the lower guide 40 when opening and closing the door device 1 will be described with reference to FIGS. 10 to 13. FIG.
The door body 20 automatically moves along the guide rail 10 and stops in a closed state even when the user does not apply force to the door body 20.例文帳に追加Next, the user applies force to the door body 20 to move the door body 20 along the guide rail 10 so that the door body 20 is in an open state. Immediately before the door body 20 is opened, the stopper member 60 attached to the door body 20 starts contacting the lower guide 40 .

FIG. 10 is a perspective view of the lower guide 40 in contact with the guide portion 62b. As the stopper body 61 approaches the lower guide 40, the inclined surface 62f of the guide portion 62b comes into contact with the base shaft portion 42, and the center of the path 63 approaches the central axis C of the base shaft portion .

FIG. 11 is a perspective view of the lower guide 40 in contact with the resistance applying portion 62c.
As the stopper body 61 further approaches the lower guide 40, the resistance applying portion 62c comes into contact with the base shaft portion . The resistance applying portion 62c is elastically deformed in the radial direction R, and suppresses relative movement in the extending direction E of the stopper member 60 with respect to the base shaft portion 42. As shown in FIG. As a result, the door body 20 decelerates.

FIG. 12 is a perspective view of the lower guide 40 in contact with the contact portion 62d.
The stopper body 61 further approaches the lower guide 40, the contact portion 62d contacts the base shaft portion 42, and the door body 20 stops in the open state. At this time, the outer peripheral surface 43a of the roller 43 also contacts the contact surface 61s of the stopper body 61 at the same time, so that the door body 20 can be stopped more reliably. Even if the user is a wheelchair user, the door body 20 is stopped in an open state and the user can safely enter the toilet booth 2.例文帳に追加

Since the base shaft portion 42 abuts against the abutting portion 62d while the resistance imparting portion 62c is sandwiched therebetween, the door main body 20 maintains the stopped state unless the user applies force. When the user moves the door body 20 along the guide rail 10 so that the door body 20 in the open state is closed, the stopper member 60 is separated from the lower guide 40 . The movement of the door main body 20 can be suppressed at a low speed until the base shaft portion 42 passes through the resistance applying portion 62c, thereby preventing the door main body 20 from suddenly starting to move.

According to the door device 1 of the present embodiment, the suspended door main body 20 can be reliably stopped in the open state. The stopper member 60 is mounted inside the recessed groove 21 of the door body 20, is not exposed to the outside, and can improve the appearance.

According to the door device 1 of the present embodiment, since the lower guide 40 has the roller 43 rotatable about the central axis C, the frictional force generated between the roller 43 and the recessed groove 21 can be suitably reduced. The opening and closing of the door main body 20 can be performed smoothly. Even if the door body 20 and the guide rail 10 are arc-shaped in plan view as in the present embodiment, the rollers 43 can smoothly open and close the door body 20 .

According to the door device 1 of the present embodiment, the function of decelerating and stopping the door body 20 can be exerted by simply attaching the stopper member 60 to the recessed groove 21 without changing the opening/closing range of the door body 20 . can.

According to the door device 1 of the present embodiment, it is easy to sufficiently secure the length in the extending direction E of the resistance applying portion 62c of the stopper member 60 . By ensuring a sufficient length in the extending direction E of the resistance applying portion 62c, the door body 20 can be reliably decelerated.
