  A first guide rail 81 and a second guide rail 82 are disposed between the two linear travel rails 7 and 7 (see FIGS. 1 and 13B). The first guide rail 81 includes a first straight guide portion 811 and a first arc guide portion 812, as shown in FIGS. The second guide rail 82 includes a second linear guide 821 and a second arc guide portion 822.

  As shown in FIG. 4B, the first guide rail 81 has a substantially inverted gate shape in cross section, and rising side portions 81b are formed on both sides in the width direction of the bottom surface portion 81a. Similarly, the second guide rail 82 has a substantially inverted gate shape in cross section, and rising side portions 82b are formed on both sides in the width direction of the bottom surface portion 82a. The interval width W between the compatible upward side portions 81b and 81b of the first guide rail 81 is slightly wider than the diameter D of the first driven roller 413 so that there is play on both sides in the diameter direction. ing. Similarly, the gap width W between the compatible upward side portions 82b and 82b of the second guide rail 82 is slightly wider than the diameter D of the second driven roller 423 so that there is play [ 4B and 8B].

  The first arc guide portion 812 of the first guide rail 81 corresponds to the first arc through hole 13 formed in the main plate 11 of the traveling body A, and has the same radius of curvature Ra. The second arc guide portion 822 corresponds to the second arc through hole 14 formed in the main plate 11 of the traveling body A, and has the same curvature radius Rb. When the radius center of the curvature radius Ra of the first arc guide portion 812 is Qa, the center angle of the first arc guide portion 812 is a right angle. Similarly, if the radius center of the curvature radius Rb of the second arc guide portion 822 is Qb, the center angle of the second arc guide portion 822 is a right angle (see FIGS. 8 to 11).

  Further, the radius of curvature Rb of the second arcuate guide portion 822 is formed larger than the radius of curvature Ra of the first arcuate guide portion 812. That is, the curvature radius Rb> the curvature radius Ra. As a result, the swinging motion of the first swinging arm portion 31 and the second swinging arm portion 32 changes, and the sliding plate portion 6 is inclined with respect to the traveling base 1 from the sliding door mounting end portion 1c. Can protrude (or jump out), in other words, appear and disappear.

  In addition, the second arc guide portion 822 may be formed in a range where the center angle is an acute angle, that is, the angle is less than 90 degrees. That is, assuming that a portion where the second arc guide portion 822 is connected to the second linear guide portion 821 is a starting point of the second arc guide portion 822 and a radius center Qb of the radius of curvature Ra is the second arc guide portion 822 from the starting point. The position of the end portion 822a is set so that the angle is less than 90 degrees.

  In the first guide rail 81 and the second guide rail 82, the first linear guide portion 811 and the second linear guide portion 821 are arranged in parallel with the linear traveling rail 7 (see FIG. 13B). . The first straight guide portion 811 and the second straight guide portion 821 are adjacent to each other in a substantially contact state. The first arc guide portion 812 and the second arc guide portion 822 are positioned at a predetermined interval so that the first driven shaft 41 and the second driven shaft 42 can move while maintaining the interval L. is doing.

  The first guide rail 81 and the second guide rail 82 are attached to the top 100 a of the cabinet 100. Specifically, the top portion 100a is mounted so as to be parallel to the opening surface 100c of the cabinet 100. The first guide rail 81 and the second guide rail 82 have the same shape in the longitudinal direction, and have a symmetrical shape. The second guide rail 82 is mounted closer to the opening surface 100c. The first guide rail 81 is mounted on the inner side of the top portion 100a.

  The first straight guide portion 811 and the second straight guide portion 821 are arranged in parallel. The first straight guide portion 811 and the second straight guide portion 821 are in contact with or close to each other. Further, two linear traveling rails 7 and 7 are arranged on the top 100a of the cabinet 100 so as to surround the first guide rail 81 and the second guide rail 82 in the width direction.

  Next, the opening / closing operation of the sliding door 200 will be described. First, the traveling body A is configured such that the traveling wheel portion 15 is reciprocally movable in the linear direction by the two linear traveling rails 7. The first driven roller 413 of the first driven shaft 41 mounted on the traveling base 1 of the traveling body A is loosely inserted into the first guide rail 81, and the second driven roller 423 of the second driven shaft 42 is inserted. It is loosely inserted in the second guide rail 82 (see FIG. 1).

  In a state where the sliding door 200 is closed with respect to the cabinet 100, the traveling body A is located at the terminal portion of the linear traveling rail 7. The first driven shaft 41 is positioned at the terminal end 812 a of the first arc guide portion 812 of the first guide rail 81, and the second driven shaft 42 is connected to the second arc guide portion 822 of the second guide rail 82. It is located at the end portion 822a (see FIG. 8). In particular, since the second swing arm portion 32 is elastically biased by the elastic member 51 in a direction in which the second swing arm portion 32 is always in a collapsed state, the second swing arm portion 32 pivots on the second swing arm portion 32 when the sliding door 200 is in the closed state. The second driven shaft 42 that is connected to the support tends to stay at the position of the terminal end portion 822 a of the second arcuate guide portion 822.

  Further, when the sliding door 200 is completely closed, the first swing arm portion 31 and the second swing arm portion 32 are in a fallen state. Even in this case, the second swing arm portion 32 is slightly inclined toward the sliding door mounting end portion 1 c side with respect to the longitudinal direction line of the traveling base 1. Further, the first driven shaft 41 and the second driven shaft 42 are always spaced by the first pivot 61 and the second pivot 62 of the slide plate 6.

  When the sliding door 200 is opened from this state, the sliding door 200 is first rotated so that the second driven roller 423 of the second driven shaft 42 becomes a swing center at the terminal portion 822a of the second arcuate guide portion 822. It opens like a door (see FIG. 9). In this way, the first driven roller 413 of the first driven shaft 41 draws an arc trajectory having the radius L as the radius, with the second driven shaft 42 as the center of oscillation, in the first arc guide portion 812. To move.

  As described above, the first driven roller 413 is movable in the width direction of the first arc guide portion 812 as well, because the first arc guide portion 812 is more compatible than the diameter D of the first driven roller 413. This is because the interval between the side portions 81b and 81b is widened (see FIG. 4B), and when the sliding door 200 is slightly inclined and moves to some extent with the interval L as the swing radius. The first driven roller 413 abuts on one rising side portion 81b of the first arc guide portion 812 and moves toward the first linear guide portion 811 along the first arc guide portion 812 ( At this time, the traveling body A starts to move in the linear direction along the rail 7 for linear traveling.

  Since the first driven shaft 41 and the second driven shaft 42 move together so as to always maintain the distance L, the second driven roller 423 together with the second driven shaft 42 follows the second arc guide portion 822. Then, it moves toward the second linear guide portion 821. When the first driven shaft 41 reaches the boundary between the first arc guide portion 812 and the first linear guide portion 811, the sliding door 200 is separated from the opening surface 100 c of the cabinet 100 by the maximum interval Kmax, And it is set so that it may become a parallel state (refer FIG. 11). In this state, the sliding door 200 moves in the door opening direction together with the traveling body A.

  The sliding door 200 moves in parallel with the opening surface 100c of the cabinet 100 and is separated from the maximum distance Kmax with the traveling body A. Therefore, as shown in FIG. The sliding door 200 can be moved so as to overlap the surface side of the sliding door 200 in the closed state, and the opening operation is completed. When the sliding door 200 in the open state is closed, the traveling body A moves again toward the closing side of the linear traveling rail 7, and the first driven shaft 41 and the second driven shaft 42 are moved to the first arc guide portion 812. And it moves along the 2nd circular arc guide part 822, and it will be in a closed state.

  At this time, since the second swing arm portion 32 is elastically biased by the elastic member 51 so as to fall, the first arc guide portion 812 and the second arc are not required by human power. The first driven roller 413 and the second driven roller 423 move to the guide portion 822 toward the respective terminal portions 812a and 822a, and the sliding door 200 can be automatically closed.

  Further, at least one of the first driven shaft 41 and the second driven shaft 42 is mounted with an auxiliary guide wheel 43 that rotates on a vertical surface, and the auxiliary guide wheel 43 is connected to the main plate 11 of the traveling body A. It is in contact with the back side. Furthermore, a second auxiliary wheel 44 may be attached. The second auxiliary wheel 44 is mounted on the main plate 11 and in the vicinity of the first arc through hole 13. The second auxiliary wheel 44 has a second guide wheel 442 mounted on top of a columnar portion 441. The second guide wheel 442 supports the slide plate portion 6 together with the auxiliary guide wheel 43 so as to maintain a horizontal shape from the back surface side.

  Furthermore, as shown in FIGS. 1 and 2, sliding door cushions 9 are mounted at the door closing side end 1b of the traveling body A and at the corners of the sliding door mounting end 1c. The sliding door cushion 9 serves to alleviate impacts such as a collision at an end in the moving operation of the sliding door 200. The sliding door cushioning device 9 is provided with a hook member that moves while buffering the elastic biasing force by releasing the temporary stop state, and the locked portion mounted on the cabinet 100 side and the hook member are locked. Thus, the temporarily stopped state of the hook member is released, and the traveling body A can move with the door closing side end 1b as the head. The sliding door cushion 9 serves to make the opening of the sliding door 200 more reliable.

  Further, only the first guide rail 81 and the second guide rail 82 are mounted on the back side of the bottom 100b of the cabinet 100, and the linear travel rail 7 is not mounted (see FIG. 13C). In addition, a horizontal bracket is attached to the lower end portion of the sliding door 200, and a first driven roller 413 and a second driven roller 423 are attached, move together with the traveling body A above the sliding door 200, and move together with the slide plate portion 6 to the cabinet. The outside and the inside of 100 can be protruded (projected out). FIG. 12 is provided with the sliding door 200 symmetrically with respect to the cabinet 100, and each traveling body A has a structure that is arbitrarily opposite. FIG. 12B is a schematic view showing a state in which the two sliding doors 200 are both closed. An imaginary line indicates that one sliding door 200 opens so as to overlap the other closed sliding door 200.
