A pair of left and right rubber members 122 are disposed. This rubber member 122 is an easily deformable member that constitutes the lower end portion of the shoji 10 together with the lower frame member 12 and is formed of an elastic body. In this embodiment, the rubber member 122 is provided. However, in the present invention, the rubber member 122 may be formed of a soft material.

  In such a shoji 10, the door wheels 44 and 54 constituting the first door wheel unit 40 and the second door wheel unit 50 are respectively placed on the upper rail 5, and the first engagement unit 20, the shaft member 41, and the like are pressed by the compression coil spring KB. Are engaged, and the second engagement unit 30 and the shaft member 51 are engaged with each other, so that the rubber member 122 is suspended from the floor surface 6 by the urging force of the compression coil spring KB. It is in a state separated from. When each door wheel 44, 54 rolls on the upper rail 5, the shoji 10 can be opened and closed along the extending direction of the upper rail 5, that is, the front-rear direction. In addition, the code | symbol 7 in FIG. 6 is the bracing member provided in the floor surface 6. FIG. This bracing member 7 enters the lower end groove portion 121 of the lower frame member 12 and restricts the shoji 10 from being displaced along the left-right direction during opening / closing movement.

  A plurality of guide members (two in the illustrated example) are provided, and have a first guide portion 60 and a second guide portion 70. Each of the first guide part 60 and the second guide part 70 is made of, for example, a resin material.

  The first guide portion 60 is arranged such that a part of the first guide portion 60 protrudes downward from the upper rail 5 by being partially inserted into the front end portion of the upper rail 5 from the front side. A first inclined surface 61 that is inclined downward toward the front from the rear end portion is formed at the lower portion of the first guide portion 60, and a first holding recess is formed on the front side of the first inclined surface 61. 62 is formed.

  The first inclined surface 61 is a surface that is in sliding contact with the top 22a of the first protrusion 22 when the shoji 10 is opened and closed. The first holding recess 62 is provided so as to open downward in a first horizontal surface 63 continuous with the first inclined surface 61. This first holding recess 62 closes the opening 1 when the shoji 10 is closed and moved to the closed position, that is, the vertical frame member 13 on the left side of the shoji 10 abuts against the front wall 3. In this case, the top portion 22a of the first projection 22 is allowed to enter and the shoji 10 is held in the closed position.

  The second guide portion 70 is disposed at a location on the rear side of the upper rail 5 with respect to the first guide portion 60 so that the lower portion protrudes downward from the upper rail 5 with screws. A second inclined surface 71 is formed in the lower portion of the second guide portion 70 so as to be inclined downward as it goes forward from the rear end portion. A second holding recess is formed on the front side of the second inclined surface 71. 72 is formed.

  The second inclined surface 71 is a surface that is in sliding contact with the top 32a of the second protrusion 32 when the shoji 10 is opened and closed. More specifically, the second inclined surface 71 is a case where the shoji 10 is opened and closed, and when the top portion 22a of the first projecting portion 22 is in sliding contact with the first inclined surface 61, the top portion of the second projecting portion 32. 32a is a surface in sliding contact with 32a.

  The second holding recess 72 is provided so as to open downward in a second horizontal plane 73 continuous with the second inclined surface 71. The second holding recess 72 is formed when the shoji 10 is closed and closed at the closed position, that is, when the top portion 22a of the first protrusion 22 enters the first holding recess 62. The entrance of the top portion 32a is allowed and the shoji 10 is held in the closed state at the closed position.

  As described above, the second guide portion 70 is in contact with the second protrusion portion 32 when the first guide portion 60 is in contact with the first protrusion portion 22, and the first protrusion portion is in the first holding recess 62 of the first guide portion 60. When the top portion 22 a of 22 enters, the second holding recess 72 is disposed at a position where the top portion 32 a of the second protrusion 32 can enter.

  Further, as shown in FIG. 6, the second guide portion 70 is formed with a passage groove portion 74 that opens downward. The left and right width of the passage groove 74 is smaller than the left and right width of the second protrusion 32 and larger than the left and right width of the first protrusion 22, and the first protrusion when the shoji 10 is opened and closed. The part 22 is allowed to pass.

  In the joinery having the above-described configuration, when the shoji 10 is in a state where the opening 1 as shown in FIG. 3 is opened, the first protrusion 22 and the second protrusion 32 are located at any location. Further, the shoji 10 is biased upward by the compression coil spring KB and the lower end portion is separated from the floor surface 6. When the shoji 10 is closed and moved forward, the top 22a of the first protrusion 22 abuts on the first inclined surface 61 of the first guide 60, and the top 32a of the second protrusion 32 is the second guide. It abuts on the second inclined surface 71 of the portion 70.

  Thus, when the shoji 10 is closed and moved from the state in which the top 22a of the first protrusion 22 abuts on the first inclined surface 61 and the top 32a of the second protrusion 32 abuts on the second inclined surface 71, As shown in FIG. 7, the top 22a of the first protrusion 22 is in sliding contact with the first inclined surface 61, and the top 32a of the second protrusion 32 is in sliding contact with the second inclined surface 71. Due to the inclination of the surface 61 and the second inclined surface 71, the shoji 10 descends against the urging force of the compression coil spring KB.

  Then, as the shoji 10 is closed, the top 22a of the first protrusion 22 contacts the lowermost portion of the first inclined surface 61, and the top 32a of the second protrusion 32 contacts the lowermost surface of the second inclined surface 71. Then, the shoji 10 is in the most lowered state, and the rubber member 122 of the lower frame member 12 is slightly elastically deformed by contact with the floor surface 6.

  Thereafter, the top 22a of the first projection 22 is brought into sliding contact with the first horizontal surface 63 and the top 32a of the second projection 32 is brought into sliding contact with the second horizontal surface 73 by the closing movement of the shoji 10, and the shoji 10 is further moved to the closed position. When reaching, as shown in FIG. 8, the top 22a of the first protrusion 22 enters the first holding recess 62 by the biasing force of the compression coil spring KB, and the top 32a of the second protrusion 32 is attached to the compression coil spring KB. The force enters the second holding recess 72 and the shoji 10 is held in a state in which the opening 1 is closed. At this time, the rubber member 122 of the lower frame member 12 is in contact with the floor surface 6.

  On the other hand, when the shoji 10 that is held in the state in which the opening 1 is closed is moved rearward, the following occurs. By the opening movement of the shoji 10, the top 22 a of the first projection 22 is detached from the first holding recess 62, and the top 32 a of the second projection 32 is detached from the second holding recess 72. When the top 22a of the first projection 22 is in sliding contact with the first inclined surface 61 and the top 32a of the second projection 32 is in sliding contact with the second inclined surface 71 as the shoji 10 is opened, the shoji 10 is The rubber member 122 of the lower frame member 12 is separated from the floor surface 6 by being raised by being biased by the compression coil spring KB.

  After that, when the shoji 10 is opened, the first projecting portion 22 is separated from the first guide portion 60, and when the second projecting portion 32 is separated from the second guide portion 70, the shoji 10 is raised most by the compression coil spring KB. It is urged to the state, and it moves to open backward in such a raised state. With this opening movement, even if the first protrusion 22 reaches the second guide part 70, there is no possibility that the first protrusion 22 will interfere with the second guide part 70 by passing through the passage groove 74 of the second guide part 70.

  As described above, according to the joinery that is an embodiment of the present invention, the shoji 10 is opened and closed in a state where the rubber member 122 is separated from the floor surface 6 by being biased upward by the compression coil spring KB. The first guide portion 60 is in contact with the top portion 22a of the first projection portion 22 provided on the shoji 10 that is closed, and the second guide portion 70 of the second projection portion 32 provided on the shoji 10 is provided. Since the shoji 10 is lowered against the urging force of the compression coil spring KB by coming into contact with the top portion 32a and the rubber member 122 is in contact with the floor surface 6, the upper rail 5 itself is uneven. In addition, when the shoji 10 is closed at the closing position, there is no possibility that, for example, a toe of a child or the like enters the floor surface 6. Therefore, it is possible to reduce the cost while preventing a finger or the like from entering between the shoji 10 closed at the closing position and the floor surface 6.

  According to the joinery, when the shoji 10 is closed at the closing position, the top portion 22a of the first projection 22 enters the first holding recess 62, and the top 32a of the second projection 32 is the second holding recess. Since it is made to approach 72, the shoji 10 can be satisfactorily held in a state where it is closed at the closed position.

  According to the joinery described above, the rubber member 122 is provided on the lower frame member 12 of the shoji 10, so that the portion that can contact the floor surface 6 at the lower end of the shoji 10 is configured by the rubber member 122. When the shoji 10 is closed at the closing position, it is possible to increase the frictional resistance with the floor surface 6 and to prevent the shoji 10 from fluttering due to wind or the like. In addition, it is possible to prevent injuries caused by hitting the toes or the like when the shoji 10 is opened and closed.

  According to the joinery, since the passage groove portion 74 that allows the first projection portion 22 to pass is formed in the second guide portion 70, the first projection portion 22 and the second guide portion 70 are There is no possibility of interference, and the opening / closing movement of the shoji 10 can be performed satisfactorily.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the above-described embodiment, when the shoji 10 is closed at the closing position, the shoji 10 closes the opening 1. However, in the present invention, the shoji closes a part of the opening. Therefore, the opening may be closed by closing each of the plurality of shojis at a predetermined closing position.

  In the above-described embodiment, the guide member is configured by the first guide portion 60 and the second guide portion 70. However, in the present invention, the guide member may be a single member or a plurality of guide members. Is not particularly limited, but the number is preferably the same as the number of protrusions provided on the shoji.

  In the embodiment described above, the compression coil spring KB, which is the urging means, is provided so as to wind the shaft members 41, 51. However, in the present invention, the urging means is provided in any form. It doesn't matter. For example, as in the present embodiment, the present invention is not limited to the state in which the lower end portion of the shoji 10 is separated from the floor surface by being biased upward by the biasing means such as the compression coil spring KB. In this case, a tension coil spring may be used as the biasing means. In this way, when the tension coil spring is used as the urging means, one end of the tension coil spring may be connected to the locking plate (42, 52) and the other end connected to the door unit (40, 50). 10) is suspended from a tension coil spring, and the downward movement of the shoji (10) is restricted in a state where the tension coil spring is stretched to some extent, and further from that state, the shoji (10) is further guided by the guide members (first guide portion 60, second guide). By being pushed down by the guide part 70), the spring further extends and the lower end of the shoji (10) comes into contact with the floor surface (6).

  In the embodiment described above, the first projecting portion 22 and the second projecting portion 32 have been described as the abutting portions in contact with the guide members (the first guide portion 60 and the second guide portion 70). The contact portion is not limited to a shape protruding upward like the protrusions 22 and 32, and may be realized by, for example, a corner portion of the shoji (10).

  In the above-described embodiment, when the shoji 10 is closed at the closing position, the lower end portion (rubber member 122) of the shoji 10 is in contact with the floor surface 6, but in the present invention, the shoji (10 ) Is closed at the closed position, the separation distance between the lower end of the shoji (10) and the floor surface (6) may be smaller than the separation distance when the shoji (10) is opened and closed. .
