Description

  The present invention relates to a sliding door including a door plate that moves in parallel so as to move back and forth between a predetermined reference surface and a traveling surface parallel to the reference surface.

  A door plate that translates between a predetermined reference surface and a traveling surface parallel to the reference surface, and a sliding door that can be closed so that the door plates are flush with each other by combining a plurality of such door plates. Is conventionally known (for example, Patent Document 1). However, the sliding door according to Patent Document 1 has a problem that the effective height of the entrance of the sliding door is lowered by a guide rail attached to the ceiling surface and the floor surface to guide the door plate, and the room is barrier-free. There was a problem that could not be made. Then, the sliding door which solved these problems is developed (for example, patent documents 2).

  As shown in FIG. 13, the sliding door 1 according to Patent Document 2 includes a linear rail 2 having a substantially “U” -shaped cross section attached to the ceiling surface X, a runner 3 that travels inside the rail 2, and The door plate 4 is suspended from the runner 3, and the runner 3 and the door plate 4 are connected via a rotation link 5. Therefore, when the rotation link 5 rotates, the door plate 4 can move in parallel so as to go back and forth between a predetermined reference surface and a traveling surface parallel to the reference surface.

However, the door plate 4 is suspended in a “cantilever” state by the runner 3 via the rotation link 5 extending in the horizontal direction, and the weight of the door plate 4 is applied to the rotation link 5 as a bending moment. For this reason, when the door plate 4 is heavy, the rotation link 5 is bent and the smooth movement of the door plate 4 is obstructed, and there is a possibility that the sliding door 1 cannot be opened and closed. Further, since there is no member that restricts the movement of the door plate 4 at the lower part of the door plate 4, there is a problem that the door plate 4 undesirably swings with the upper end as a fulcrum.

  The present invention has been developed in view of such problems of the prior art. Therefore, a main problem of the present invention is to provide a sliding door provided with a door plate that moves smoothly even if it is heavy, while maintaining an indoor barrier-free state, without undesirably swinging.

  According to the first aspect of the present invention, the upper guide rail 12 attached to the ceiling surface A, the lower guide member 16 attached to the floor B, and the upper guide rail 12 while being guided by the lower guide member 16 The sliding door 10 includes a door plate 14 that travels along the door plate 14. The door plate 14 is attached to the plate-like door plate main body 20 and the upper end portion of the door plate main body 20, and is suspended from the upper guide rail 12 so as to freely run. It has a lower member 21 and a lower guide groove 22 that is provided at the lower end of the door plate body 20 and receives the lower guide member 16 so as to be relatively movable. The upper guide rail 12 has a predetermined reference surface K. A traveling unit 18 that travels the door plate 14 on a traveling surface S parallel to the traveling surface S, and a parallel moving unit 19 that translates the door plate 14 so as to move back and forth between the reference surface K and the traveling surface S. The lower guide member 16 is provided in the fixed portion 27 fixed to the floor B, the rotary arm 32 rotatably attached to the fixed portion 27, and the rotary arm 32, and is received in the lower guide groove 22. The sliding door 10 has a guide pin 34 that is rotated and the turning arm 32 is rotated following the parallel movement of the door plate 14.

  According to the present invention, the upper guide rail 12 has the parallel moving part 19 that translates the door plate 14, so that the sliding door 10 can move the door plate 14 even without the pivot link like the sliding door 1 according to Patent Document 2. Since it can move in parallel, the door plate 14 can be suspended vertically downward from the upper guide rail 12. At this time, the weight of the door plate 14 acts only as a stress that pulls the upper guide rail 12 vertically downward. Further, the lower guide groove 22 provided on the lower end surface of the door plate 14 movably receives the guide pin 34 of the lower guide member 16 attached to the floor surface B, and the rotating arm 32 follows the movement of the door plate 14. By rotating, the movement of the lower end portion of the door plate 14 is always restricted by the lower guide member 16. Furthermore, since the long lower guide groove 22 is provided in the lower end surface of the door plate 14, the lower guide member 16 does not need to be a long member.

  The invention described in claim 2 is the sliding door 10 described in claim 1, “It is provided with two door plates 14, and the rotating arm 32 is rotatably attached to the fixed portion 27 at the center thereof. And guide pins 34 are provided at both ends thereof.

  According to the present invention, since the two door plates 14 are connected via the rotating arm 32, one door plate 14 is moved so that one of the two door plates 14 is housed in one lower guide groove 22 so as to be able to run. The guide pin 34 moves, the turning arm 32 turns, and the other guide pin 34 also moves. Thereby, the other door plate 14 having the other lower guide groove 22 that accommodates the other guide pin 34 also moves.

  According to the third aspect of the present invention, in the sliding door 10 according to the first or second aspect, “the lower guide member 16 is configured such that the rotating arm 32 positioned at the start and end points of the rotation undesirably rotates. It is characterized by comprising a rotation preventing member 38 for preventing.

  According to the present invention, the rotation arms 32 positioned at the start point and the end point that rotate with respect to the fixed portion 27 do not undesirably rotate.

  According to the present invention, the weight of the door plate acts only as a stress that pulls the upper guide rail vertically downward. Smooth movement is not hindered. Further, since the movement of the lower end of the door plate is always restricted by the lower guide member, the door plate does not undesirably swing around the hanging member as a fulcrum. Furthermore, since it is not necessary to make the lower guide member long, the lower guide member can be reduced in size, so that the lower guide member can be attached to the floor without causing a barrier-free obstacle.

  Moreover, according to the invention which concerns on Claim 2, when one door board is moved, since the other door board will also move, even if it is a case where the board thickness of a door board is thick, the reference plane to which a door board moves, and a running surface, The space required for installing the sliding door can be reduced by minimizing the distance.

  Furthermore, according to the invention which concerns on Claim 3, since the rotation arm located in the starting point and end point of rotation does not rotate undesirably, a doorplate does not translate undesirably.

  The present invention will be described below with reference to the drawings. FIG. 1A is a front view showing a sliding door 10 according to the present invention, and FIG. 2A is a side view showing the sliding door 10 according to the present invention.

  The upper guide rail 12 is a long member having a substantially “U” -shaped cross section, and is attached to the ceiling surface A. As shown in FIG. 3, the upper guide rail 12 has an opening with a “U” -shaped cross section so that a suspension wheel 21 (described later) attached to the door plate 14 can travel inside the “U” -shaped cross section. It is attached to the ceiling surface A via the upper frame 17 with the part facing downward. Further, as shown in FIG. 4, the upper guide rail 12 includes a linear traveling unit 18 that travels the door plate 14 on a traveling surface S parallel to a predetermined reference surface K, a reference surface K, and a traveling surface S. There are two parallel moving parts 19 which are curved parts that translate the door plate 14 so as to move between the two. The parallel moving unit 19 is provided at a substantially central portion of the traveling unit 18 and one end of the traveling unit 18. In this embodiment, when the two upper guide rails 12 are combined, when the sliding door 10 is closed, the two door plates 14 are positioned on the reference plane K and are flush with each other, and the sliding door 10 is opened. The door plate 14 can be translated to the traveling surface S so that the two door plates 14 do not interfere with each other. In addition, a decorative curtain E for blinding the upper guide rail 12 is attached to the side surface of the upper guide rail 12 (see FIG. 2A).

  The door plate 14 includes a door plate main body 20 that partitions the opening D of the sliding door 10, a suspension wheel 21 that is attached to the upper end surface of the door plate main body 20, and a lower guide provided on the lower end surface of the door plate main body 20. And a groove 22. In addition, the sliding door 10 which concerns on a present Example is provided with the 1st door plate 14a and the 2nd door plate 14b.

  The suspension vehicle 21 is a member for suspending the door plate 14 vertically downward from the upper guide rail 12 and includes two wheels 23 that travel inside the upper guide rail 12 as shown in FIG. It is attached to the door plate 14 via a shaft 24 so as to be rotatable. In the present embodiment, two suspension wheels 21 are attached to both ends of the upper end surface of the door plate 14 with respect to one door plate 14.

  As shown in FIG. 2 (b), the lower guide groove 22 is fitted with a long lower guide rail 26 having a substantially “U” -shaped cross section in a concave groove 25 carved in the lower end surface of the door plate 14. Formed. Note that a contact portion F is formed at one end of the lower guide groove 22 to contact a guide pin 34 described later when the door plate 14 is on the reference plane K (see FIG. 1B). Further, a groove provided on the lower end surface of the door plate 14 may be used as the lower guide groove 22 as it is.

  As shown in FIG. 5, the lower guide member 16 includes a fixed portion 27, a rotating arm shaft 28, two stoppers 30, two rotating arms 32, and two guide pins 34. It is attached to the floor B and used.

  The fixing portion 27 is a plate material fixed to the floor surface B, and is provided with two attachment holes 35 for inserting screws (not shown) for fixing to the floor surface B.

  The rotating arm shaft 28 is a round bar extending upward from the central portion of the fixed portion 27. Two rotating arms 32 and two washers 36 are alternately fitted on the outer periphery of the rotating arm shaft 28.

  The stopper 30 is a member formed by bending a plate material into an “L” shape. In this embodiment, the two stoppers 30 are attached to the corners of the fixed portion 27. As a result, the rotation arm 32 abuts against the stopper 30 and the movement is restricted, and the rotation arm 32 rotates about the rotation arm shaft 28 within a range of 90 °. The rotation angle of the rotation arm 32 is not limited to 90 °, and can be set as appropriate according to the positional relationship between the lower guide groove 22 and the lower guide member 16. Further, three stoppers 38, which are round magnets having the same thickness as the stopper 30, are attached to one stopper 30.

  The rotating arm 32 is a plate material having both ends processed into an arc shape, a rotating arm shaft insertion hole (not shown) is provided at one end, and a guide pin mounting hole ( (Not shown) is provided. Then, by inserting the turning arm shaft 28 into the turning arm shaft insertion hole, the turning arm 32 is rotatably attached to the turning arm shaft 28 and the guide pin is attached to the guide pin attachment hole. 34 is attached. In this embodiment, in order to make the other end portions of the two rotating arms 32 have the same height from the fixed portion 27, a bending portion 39 is provided on one rotating arm 32.

  The guide pin 34 is a member attached to the other end portion of the rotating arm 32 and is movably received in the lower guide groove 22, and includes a guide roller shaft 40 and a guide roller 42.

  The guide roller shaft 40 is a round bar inserted through the guide pin mounting hole of the rotation arm 32 in order to rotatably mount the guide roller 42 to the rotation arm 32.

  The guide roller 42 is a columnar member that is rotatably attached to the rotating arm 32 and is accommodated in the lower guide groove 22.

  By being configured as described above, as shown in FIG. 6, the lower guide member 16 has a state in which the rotating arm 32 is in a single character (a) in the horizontal direction, and one of the rotating arms 32 is rotated by 90 °. The rotated state 32 can be transformed into a single character state (c) in the vertical direction by rotating the rotated state 32 by 90 ° from the state (b) and the state shown in FIG. .

  The usage method of the sliding door 10 which concerns on a present Example is demonstrated based on FIG.

  FIG. 7A shows a state in which the sliding door 10 is closed. At this time, the two rotating arms 32 of the lower guide member 16 are in a single character in the horizontal direction in the figure, and the two door plates 14a and 14b are positioned on the reference plane K and are flush with each other. It has become. (Hereafter, the position of the door plate 14 at this time will be described as a “closed position”.) From this state, when the first door plate 14a (the door plate on the right side in the figure) is pushed upward in the figure, The door plate 14 a is guided by the upper guide rail 12 and moves to the traveling portion 18 of the upper guide rail 12. (Hereafter, the position of the first door plate 14a at this time will be referred to as “traveling position”.) At this time, the guide pin 34 is engaged with the left end portion of the lower guide groove 22 in the drawing, so that the first As the door plate 14 a moves, the guide roller 42 of the guide pin 34 is pressed against the lower guide groove 22. As a result, the rotation arm 32 rotates about the rotation arm shaft 28 as a fulcrum. When the turning arm 32 is turned 90 ° from the position shown in FIG. 7A, the state shown in FIG. 7B is reached, and the first door plate 14a does not interfere with the second door plate 14b even if it moves laterally. It has moved to. In this state, the rotation arm 32 cannot be rotated 90 ° or more by the stopper 30, so that the first door plate 14 a is not undesirably shifted from the “travel position”.

  Subsequently, when the first door plate 14a is slid in the left direction in the drawing along the “travel position” of the upper guide rail 12, the lower guide groove 22 of the first door plate 14a moves along the guide pin 34. Then, the state shown in FIG. This state is a state in which the sliding door 10 according to the present embodiment is completely opened. Therefore, the lower guide groove 22 is always guided by the guide pin 34 of the lower guide member 16 while the first door plate 14a is moved from the “closed position” to the “travel position” and while the “travel position” is moved laterally. Therefore, the first door plate 14a does not swing around the suspension wheel 21 as a fulcrum. Moreover, since there is no obstacle to traffic on the floor surface B of the opening D, barrier-free can be realized.

  In this embodiment, since the two rotating arms 32 are provided, the second door plate 14b is moved, as shown in FIG. A state having an opening D on the left side in the drawing can also be formed.

  In this embodiment, since the magnet is attached to the stopper 30 of the lower guide member 16 as the rotation preventing member 38, the rotation arm 32 is rotated when the rotation arm 32 is in contact with the stopper 30. It is sucked by the movement preventing member 38. For this reason, the stopper 30 and the rotating arm 32 are not separated from each other until a certain amount of force is applied, and the door plate 14 does not move undesirably even if it is beaten by wind or the like.

  Further, the number of rotating arms 32 is not limited to the above-described embodiment, and as shown in FIG. 8, the number of rotating arms 32 is one, guide pins 34 are provided at both ends of the rotating arm 32, and Even if the rotation arm shaft 28 is inserted into a rotation arm shaft insertion hole (not shown) provided in the central portion of the rotation arm 32 and the rotation arm 32 is attached to the fixed portion 27 so as to be rotatable. Good. By using the lower guide member 16 having such a rotating arm 32, as shown in FIG. 9, in the state (a) in which the sliding door 10 is closed, the lower guide groove 22 with which one guide pin 34a is engaged is formed. By moving one of the door plates 14a from the “closed position” to the “traveling position”, the other guide pin 34b rotates, and the guide roller 42b of the other guide pin 34b moves the side wall of the lower guide groove 22 corresponding thereto. The other door plate 14b is moved from the “closed position” to the “traveling position” (b). Therefore, as in the case where “the door plate 14 is thick and the distance from the rotary arm shaft 28 to the guide pin 34 is short”, only one door plate 14a is moved from the “closed position” to the “traveling position”. In the case where the door plates 14 interfere with each other, if one door plate 14a moves from the “closed position” to the “traveling position”, the other door plate 14b also moves from the “closed position” to the “traveling position”. (C) can be avoided.

  In the present embodiment, the suspension vehicle 21 having the two wheels 23 is used as the suspension member 21, but the suspension vehicle 21 is not limited to the suspension vehicle 21, and the door plate body 20 is suspended and moved to the upper guide rail 12. If it can be guided freely, instead of this, for example, as shown in FIG. 14 may be suspended. Further, the shape of the upper guide rail 12 is not limited to the “U” shape, and any shape that guides the door plate 14 in cooperation with the suspension member 21 may be used. For example, as the shape of the upper guide rail 12 corresponding to the suspension wheel 21 configured by the one wheel 23 described above, the shape shown in FIG.

  Further, the shape of the lower guide groove 22 is not limited to the shape of the present embodiment, and any shape that can prevent the swing of the door plate 14 in cooperation with the lower guide member 16 may be used. Further, the number of door plates 14 is not limited to two, and may be one or three or more.

  In addition, as for the material of each member, stainless steel or aluminum is used as long as it satisfies the necessary strength except that the material of the rotating arm 32 needs to have magnetism when the magnet is used as the rotation preventing member 38. A metal such as ABS, a synthetic resin such as ABS resin, and FRP can be used.

  Furthermore, in this embodiment, the rotation preventing member 38 made of a magnet is used, but instead of this, a mechanism as shown in FIGS. 11 and 12 may be used.
