The suspension wheels 41c and 41c are supported freely. The shaft portion 41a is configured not to move in the width direction with respect to the door body 11.

  The shaft portion 41a supports the door body 11 via a bearing or the like so as to rotate during the opening / closing operation.

The support bracket 41b fastens the shaft 41a to the lower side and supports the suspension wheel 41c to rotate along the opening width direction on the upper side.
The support bracket 41 b is formed of a magnetic metal material, and functions as an attracted body that is magnetically attracted by the magnetic attracting body 43.
As another example of the attracted body, the support bracket 41b itself is configured as a magnet that attracts the magnetic attracting body 43, or the portion of the support bracket 41b facing the magnetic attracting body 43 is magnetically attracted. It is good also as a structure etc. which provided the magnet so that the body 43 might attract | suck.

  The suspension wheel 41c is supported by the support bracket 41b so as to roll along the width direction of the opening, and according to the illustrated preferred example, the number of arrangements is two, but it is one or three or more. Is also possible.

  The guide rail 42 is formed so as to receive the suspension wheel 41 c from the lower side across the width direction of the opening, and is fixed to the upper frame portion 23.

Further, the magnetic attracting body 43 is a so-called permanent magnet, is disposed so as to face the end of the support bracket 41b on the door-end direction side, and is fixed to the upper frame portion 23, which is an immobile portion, via the bracket 43a. Has been.
And the elastic body 43b (refer FIG. 3) is being fixed to the edge part by the side of the support bracket 41b in this magnetic attraction body 43 so that it may contact | abut by the support bracket 41b.

According to an example shown in FIG. 3, the bracket 43a has a substantially L-shaped shape, and has a long hole 43a1 in the width direction of the opening in its fastening piece, and a fastening tool (for example, inserted through the long hole 43a1) Screws, screws, rivets, etc.).
Therefore, according to the bracket 43a, the position in the opening width direction is finely adjusted by the long hole 43a1 so that the elastic body 43b sucks the support bracket 41b when the door body 11 is substantially fully closed. Can do.

According to a preferred example of the present embodiment, the elastic body 43b is made of rubber, an elastic synthetic resin material, or the like.
In addition, this elastic body 43b should just be arrange | positioned so that it may be pinched | interposed between the magnetic attraction body 43 and the support bracket 41b (to-be-attracted body) when the door body 11 is substantially fully closed. The structure fixed to the support bracket 41b side may be sufficient.

  Further, reference numeral 44 in FIG. 2 denotes a contacted portion that is contacted by the support bracket 41b when the door body 11 is substantially fully opened. The contacted portion 44 receives an impact at the time of contact. A buffer material such as an elastic body is fixed to the contact surface so as to relax.

Next, the effect of the opening / closing door device 1 having the above-described configuration will be described in detail.
When the folding door 10 is closed from the fully opened state, it is urged in the closing rotation direction by the urging mechanism of the urging buffer mechanism 32. Therefore, when the operator performs a relatively light closing operation, FIG. As shown by the dotted line, the closing operation is performed.

  When the door-side door 11 approaches the door-side vertical frame portion 21, the support bracket 41b (subject to be attracted) is attracted by the magnetic attracting body 43, so that the urging force by the urging mechanism is weakened. Even if the damper mechanism of the biasing buffer mechanism 32 acts too strongly or the like, and the closing operation of the door body 11 is decelerated, the door body 11 is substantially fully closed by the attractive force of the magnetic attracting body 43. Can be closed up to.

  In addition, the inertial force of the door body 11 can prevent the door body 11 from passing through the fully closed position that is substantially linear with the door body 12 due to the attractive force of the magnetic attracting body 43. Even if the body 11 passes through the fully closed position, the door body 11 that has passed through can be returned to the fully closed position by the attractive force of the magnetic attracting body 43.

  Further, when the door body 11 is in the substantially fully closed position, the magnetic attracting body 43 and the movement support portion 41 (subject to be attracted) abut via the elastic body 43b. In addition, impact and the like can be reduced.

Next, another example of the opening / closing door device according to the present invention will be described. In addition, in the door apparatus shown below, about the location substantially the same as the said door apparatus 1, the detailed description which overlaps is abbreviate | omitted by attaching | subjecting the same code | symbol.
In the open / close door device 2 shown in FIG. 5, the elastic body 43b is omitted from the movement support portion 41 in the open / close door device 1, and the magnetic attracting body 43 and the support bracket 41b (subject to be sucked) are substantially completely closed. When closed, a gap s is placed so as to attract in the width direction of the opening.
More specifically, the magnetic attracting body 43 is separated by a gap s from the support bracket 41b when the door body 11 is in the fully closed position by adjusting the fixing position of the support bracket 41b in the opening width direction. Are arranged to be.
The gap s is such that the magnetic attracting body 43 and the support bracket 41b (object to be attracted) do not come into contact with each other, and the attracting force of the magnetic attracting body 43 sufficiently acts on the support bracket 41b when approaching. It is set appropriately.

  Thus, according to the opening / closing door device 2 shown in FIG. 5, substantially the same as the opening / closing door device 1, it is possible to prevent the door body 11 from being stopped at the fully closed position. When fully closed, it is possible to prevent contact noise, impact, and the like from being generated by the magnetic attracting body 43 and the support bracket 41b.

  In addition, according to the opening / closing door device 2 of the illustrated example, the elastic body 43b is omitted, but the magnetic attracting body 43, the support bracket 41b, In order to prevent the contact between the elastic body 43b and the support bracket 41b, the gap s may be secured.

  Further, the opening / closing door device 3 shown in FIG. 6 replaces the opening / closing door device 1 by replacing the magnetic attracting body 43, the bracket 43a, and the elastic body 43b with the engaged portion 45 and the bracket 46, and the support bracket 41b. The engaging portion 41d is provided.

The engaging part 41d is a roller supported so as to roll in the opening width direction with respect to the support bracket 41b.
In the illustrated example, the engaging portion 41d is a rotatable roller as a preferred example, but it is also possible to omit the roller and slide the engaging portion 45 to engage with the engaged portion 45. .

The engaged portion 45 is made of a metal material that can be elastically bent (for example, a metal material for a spring), and its proximal end is fixed to the upper frame portion 23 via the bracket 46, and This is a substantially plate-like member with the tip end projecting toward the engaging portion 41d.
More specifically, the engaged portion 45 has an engagement assisting inclined surface 45a that facilitates the engagement of the engaging portion 41d on the distal end side, and is more than the engagement assisting inclined surface 45a. A pull-in inclined surface 45b for pulling the engaging portion 41d in the engaging direction is formed on the base end side. According to the illustrated example, the pulling inclined surface 45b is formed in a substantially reverse letter shape.
The engaged portion 45 positions the intersection of the auxiliary assist inclined surface 45a and the retracted inclined surface 45b below the outer peripheral surface of the engaging portion 41d, and the door body 11 is in the fully closed position. When approaching, the engagement portion 41d passes over the intersection so as to pass.

Thus, according to the open / close door device 3 shown in FIG. 6, when the door body 11 closes due to the closing operation, the engaging portion 41 d is guided to the engaging auxiliary inclined surface 45 a and the engaged portion 45. Further, the engaging portion 41d is pulled in the engaging direction along the pulling inclined surface 45b by the elastic force of the engaged portion 45.
Therefore, the door body 11 at the time of the closing operation can be moved and stopped by the action of the engaging portion 41d and the engaged portion 45 from slightly before the substantially fully closed state until it is fully closed.
In addition, what is necessary is just to elastically deform the to-be-engaged part 45 by the operation | movement contrary to the above, when opening the door body 11. FIG.

  In addition, the open / close door device 4 shown in FIG. 7 adds an engaging portion 41e to the support bracket 41b with respect to the open / close door device 1, and the magnetic attracting body 43, the bracket 43a, and the elastic body 43b to the engaged portion 47. And it is set as the structure substituted to the bracket 48. FIG.

According to the illustrated example, the engaging portion 41 e is formed in a substantially rhombus shape that protrudes from the support bracket 41 b toward the engaged portion 47.
The engaged portion 47 is formed in a substantially frame shape sandwiching the engaging portion 41 e with an elastically deformable metal material, and supports a roller 47 a rotatably at each of both end portions thereof. It is fixed to the upper frame part 23 which is a stationary part.
Note that the engaged portion 47 may be configured such that the roller 47a is omitted and the engaging portion 41e is slid and engaged.

Thus, according to the opening / closing door device 4 shown in FIG. 7, when the door body 11 is closed, the engaging portion 41e elastically expands both the rollers 47a, 47a of the engaged portion 47. 47a is inserted and engaged.
Therefore, it can prevent that the door body 11 used as the substantially fully closed state does not stop.
In addition, what is necessary is just to elastically deform the to-be-engaged part 47 by the operation | movement contrary to the above, when opening the door body 11. FIG.
