Further, on the upper surface of both end portions of the load member 39 described above, stop portions 60, 60 for restricting the maximum displacement when the load member 39 swings up and down around the connecting member 58 are projected. The compression spring 59 made of a coil spring is wound around the stop portion 60. Here, the stopper 60 is formed integrally with the upper portion of the guide member 44 and protrudes upward from the hole 61 formed in the upper surface of the load member 39 described above.

  Further, anti-vibration rubber is used as the connecting member 58, and a space is formed between the upper surface of the load member 39 and the upper surface of the recessed groove portion 20 of the panel body 9 via the anti-vibration rubber. The connecting member 58 has a structure in which metal mounting plates 63, 63 are firmly fixed to the upper and lower surfaces of the rubber main body 62, and the mounting plates 63, 63 are connected to the upper surface of the load member 39 and the panel main body 9 described above. Are attached to the upper surface of the concave groove 20 by screwing. Since the connecting member 58 is elastically deformable, the panel main body 9 can swing up and down with respect to the loading member 39, and one end of the panel main body 9 is elastically biased upward by the compression spring 59. The connecting member 58 may be a pivotable hinge. Here, the load member 39 and the baseboard member 40 are inclined according to the unevenness of the floor surface F, and the panel main body 9 is set in a vertical posture, but the minimum swing necessary for that is allowed, Further, the height of the stopper 60 is set so as to limit unnecessary swinging during movement of the movable panel 1.

  As shown in FIG. 16 (a), when the baseboard member 40 is raised, the baseboard member 40 is accommodated in the concave groove portion 20 of the lower frame 13, and the compatible upper plates 64 and 64 are disposed in the vertical direction. It is located in the slit grooves 25, 25 of the frame 11. Further, the protruding end portion of the baseboard member 40 is provided with a hard synthetic resin contact member 65 having the same end shape as the outer shape of the packing 10. Further, the engaging grooves 22 and 22 on the inner surfaces of the lower ends of the vertical plates 19 and 19 of the lower frame 13 are provided with sliders 66 and 66 slidably contacting the outer surface of the baseboard member 40 to prevent back and forth rattling. Yes.

  Then, when the movable panel 1 is moved along the guide rail 4 and the abutting member 65 of the projecting portion of the baseboard member 40 collides with the side wall of the wall surface W or other preceding movable panel 1, A lateral external force is applied so that the baseboard member 40 is pushed relatively below the panel body 9 by the impact force. Actually, the baseboard member 40 is stopped and restricted in movement, but a relative lateral external force acts by the inertial force of the panel body 9. Accordingly, as the roller 46 rolls downward on the inclined guide surface 45, the baseboard member 40 is lowered, and after the baseboard member 40 contacts the floor surface F, the roller base member 40 is placed on the roller 46. When the inclined guide surface 45 rises and raises the panel main body 9 and finally reaches the position where the lowermost recess 53 is engaged with the roller 46, the baseboard member 40 is positioned immediately below the panel main body 9. Become. As a result, the rolling wheels 2,... Float up and the baseboard member 40 comes into pressure contact with the floor surface F to enter a movement restricted state (see FIG. 16B).

  Here, in the movement restricted state where the baseboard member 40 is in pressure contact with the floor surface F and located directly below the panel body 9, the roller 46 is engaged in a metastable state with the concave portion 53 at the bottom of the inclined guide surface 45. In addition, the elastic biasing force of the tension coil spring 49 acts in a direction in which the panel main body 9 is retracted, that is, the concave portion 53 acts in a direction away from the roller 46, so that it is difficult to say that it is stable. . In particular, since the movable panel 1 located in the direction changing portion 4A is only supported by the guide roller 3 at the center of the upper end, there is a risk of rotating or shifting in the front-rear and left-right directions.

  Therefore, as shown in FIGS. 12 to 14, the cross-sectional shape of the packing 10 is devised so that the packings 10, 10 on the side ends of the adjacent moving panels 1, 1 are concavo-convexly fitted, and the moving panel 1 The stopper 8 which latches to the said floor F is provided in the lower end part of the rear side of this movement direction. Here, the packing 10 is symmetrical with respect to the center line, and has a shape in which the unevenness on the front side and the unevenness on the back side are engaged with each other. Accordingly, the packings 10 and 10 attached to both the left and right sides of the movable panel 1 are mounted in the same direction so as to be vertically slidably engaged with the locking pieces 17 and 17 of the vertical frame 11.

  As shown in FIGS. 3 to 5, 19, and 20, the stopper 8 is made of metal at the lower end of a hard synthetic resin main body 67 that has the same cross-sectional shape as the outer cross-sectional shape of the packing 10. A pin 68 is protruded, and vertical grooves 69, 69 formed on both sides of the main body 67 are slidably engaged with the distal bent portions 70, 70 of the pair of locking pieces 17, 17 of the vertical frame 11, The main body 67 is lowered to drop the pin 68 into an engagement hole 71 formed in advance at a predetermined position on the floor surface F so as to be engaged. Here, the position where the stopper 8 is provided is ensured by shortening the lower end of the packing 10, and when the stopper 8 is raised, the outer appearance is united with the packing 10. Further, the stopper 8 is prevented from descending by its own weight due to the frictional force between the longitudinal grooves 69 and 69 and the bent end portions 70 and 70 of the locking pieces 17 and 17.

  Further, a concave portion 72 for hooking a finger is formed in the upper and lower intermediate portions on the outer surface of the main body portion 67 of the stopper 8 to improve operability. Similarly to the packing 10, since the trapezoidal protrusion 73 is provided at the center of the main body 67, the end of the protrusion 73 is surely provided even if the depth of the recess 72 is shallow. You can hang your finger on. Further, a bulging portion 74 that stops against the lower end of the vertical frame 11 is formed at the lower end portion of the main body portion 67. The pin 68 is inserted from below into a circular hole 75 formed at the center of the lower end of the main body 67, and communicates with the circular hole 75 from a recess 76 formed on the back side of the protrusion 73 of the main body 67. A screw 78 passed through the through hole 77 is screwed into the pin 68 and fixed.

  The main body 67 of the stopper 8 of the movable panel 1 arranged in series in advance is in contact with the abutting member 65 at the distal end of the baseboard member 40 of the subsequent movable panel 1 and the main body 67. Although the contact member 65 is displaced downward with the contact member 65 being in contact with each other, since it is made of a hard synthetic resin and is excellent in slidability, a smooth sliding operation can be realized.

  In the case where the movable panel 1 is moved along the guide rail 4 and stored from the state where the rolling base member 40 is pressed against the floor surface F and the rolling wheels 2 are lifted (movement restricted state). First, the stopper 8 is lifted to remove the pin 68 from the engagement hole 71 of the floor surface F, and pulling it by holding the side portion of the panel body 9, thereby disengaging the lowermost concave portion 53 from the roller 46. The panel body 9 is lowered by the weight of the panel body 9 and the rolling wheels 2,... Are grounded to the floor surface F, and the baseboard member 40 is moved up and moved by the elastic biasing force of the tension coil spring 49. It becomes a state.

  Next, the smoother 7 provided at the upper end portion on the front side in the movement direction of the movable panel 1 will be described with reference to FIGS. 3, 4 and 7. As described above, since the inclined step 4C is provided at the boundary between the direction changing portion 4A and the series holding portion 4B of the guide rail 4, the movement panel 1 is moved from the direction changing portion 4A to the series holding portion 4B. The smoother 7 is provided so that smooth movement can be performed.

  The smoother 7 has a Z-shaped mounting bracket 79 fixed to the end of the upper frame 12 of the upper frame 12 of the panel main body 9 in the moving direction, and a rotation axis perpendicular to the upper piece 80 of the mounting bracket 79. A pair of rollers 81 are provided in the concave groove 20 so that a part thereof protrudes from the side end of the panel body 9 in the moving direction. The distance between the outer sides of the rollers 81 and 81 is set to be equal to or slightly narrower than the distance between the hanging plates 27 and 27 of the guide rail 4. Then, when the movable panel 1 is moved from the direction changing portion 4A to the series holding portion 4B, the rollers 81, 81 first come into contact with both the hanging plates 27, 27 of the series holding portion 4B corresponding to the inclined step 4C. Then, the rollers 81 and 81 are guided between the both hanging plates 27 and 27. After that, since both hanging plates 27, 27 of the series holding portion 4B are located in the recessed groove portion 20 of the upper frame 12, the sliders 34, 34 provided on the inner surfaces of the upper ends of the two vertical plates 19, 19 are both suspended plates. Since the guides are in sliding contact with the outer surfaces of 27 and 27, they move smoothly in a straight line.

  In this embodiment, the pair of rollers 81 and 81 are provided, but the number of rollers may be one, or a slider may be used instead of the rollers. In either case where a single roller is provided or a slider is provided, a part of the roller comes from the side end of the panel main body 9 so as to come into contact with both hanging plates 27, 27 of the series holding portion 4B first. It needs to protrude in the moving direction.

  Here, although the smoother 7 is not necessary for the movable panel 1 positioned in the direction changing portion 4A of the guide rail 4 and aligned in series, the above-described closing member 37 is necessary. The closing member 37 will be described in more detail with reference to FIGS. 9 to 11 and FIGS. The closing member 37 is a die having a substantially U-shaped cross section that is opened downward, has the same outer shape as the hanging plates 27 and 27 of the guide rail 4, and has a groove in the upper frame 12 of the panel body 9. Both end portions are held in a fixed position in 20 so as to be movable up and down, and elastically biased upward. That is, the reference members 82 and 82 made of L-shaped metal fittings are attached to both end portions of the concave groove portion 20, and the reference members are attached to both end portions in the groove portion of the closing member 37 by the holding members 83 and 83. The members 82 and 82 are surrounded from the outside, and the movement of the closing member 37 is limited only in the vertical direction. A compression coil spring 84 is interposed between the bottom surface of the recessed groove portion 20 of the upper frame 12 and the upper surface of the closing member 37 and supported by the reference member 82 and the holding member 83.

  Specifically, the reference member 82 has a horizontal plate 82A and a vertical plate 82B that are screwed into the groove 20 of the upper frame 12, and the lower portion of the compression coil spring 84 is positioned on the horizontal plate 82A. An opening 82C is formed, and a pair of left and right screw holes 82D and 82D are appropriately provided in the upper part of the vertical plate 82B. The holding member 83 includes a horizontal plate 83A screwed to the upper surface plate of the closing member 37 and a vertical plate 83B having a U-shaped cross section for slidably receiving the vertical plate 82B of the reference member 82. A protruding piece 83C that engages with the upper portion of the compression coil spring 84 is formed downward at the end of 83A, and a vertically long oblong hole is formed in the vertical plate 82B at the same interval as the screw holes 82D and 82D of the reference member 82. 83D and 83D are appropriately formed. The vertical plate 82B of the reference member 82 is received in the concave groove of the vertical plate 83B of the holding member 83, and the lower portion of the compression coil spring 84 is located in the opening 82C of the reference member 82, and the upper portion Is interposed in a state of engaging with the protruding piece 83C of the holding member 83, and elastically biases the closing member 37 upward.

  Since the closing member 37 is elastically urged upward at the upper end portion of the moving panel 1 located in the direction changing portion 4A of the guide rail 4, the moving panel 1 can be used in any state and on the floor surface. Even if F is uneven, the contact members 38, 38 provided along both side edges of the upper end of the closing member 37 are pressed against the lower surfaces of the sliding pieces 28, 28 of the direction changing portion 4 </ b> A to close the gap. Can do. In the state where the contact members 38 and 38 are in contact with the lower surfaces of the sliding pieces 28 and 28, screws 85 passed from the outside through the long holes 83 </ b> D and 83 </ b> D of the holding member 83 are screw holes 82 </ b> D of the reference member 82. , 82D, and the vertical plate 82B and the vertical plate 83B are fixed to fix the position of the closing member 37. As a matter of course, as shown in FIGS. 9 and 11, an opening 86 through which the rotation shaft 29 of the guide roller 3 can be inserted is formed in the upper surface plate of the closing member 37.

  Here, in the movement restriction state where the baseboard member 40 is lowered and pressed against the floor F, the panel body 9 is slightly raised by the amount of the rolling wheels 2,. Since it can be moved up and down and elastically biased upward, the displacement can be absorbed, and the contact members 38 and 38 can always be brought into contact with the lower surfaces of the sliding pieces 28 and 28 of the guide rail 4.

  Next, based on FIG.2 and FIG.14, the structure of the said opening-and-closing panel 6 is demonstrated easily. The structure of the open / close panel 6 is such that, in the movable panel 1 including the closing member 37, a closing member 87 similar to the closing member 37 can be adjusted up and down in the recessed groove portion 20 of the lower frame 13 instead of the lift mechanism 5. Provided. Here, the vertical adjustment mechanism of the closing member 87 is performed by tightening the reference members 82 and 82 and the holding members 83 and 83 with screws 85. In the opening / closing panel 6, a horizontal beam 88 is used instead of the horizontal beam 14. The shape of the horizontal crosspiece 88 when viewed obliquely from above is the same as that of the horizontal crosspiece 14. However, a groove portion opened downward is formed on the lower surface on both sides of the groove portion 23 so that the groove portion can be used as a handle.

  In addition, slide buttons 89 are provided on the front and back surfaces of the vertical frame 11 on the front and back sides of the vertical frame 11 on the free end side of the open / close panel 6, and the upper end of the operating rod 90 passed through the vertical frame 11 is disposed on the slide button. In addition, the lower end of the operation rod 90 can be projected and retracted from the lower end of the vertical frame 11. Then, with the open / close panel 6 closed in series with the other movable panel 1, the slide button 89 is lowered, and the lower end of the operation rod 90 is projected downward to be formed in advance on the floor F. The closed state is maintained by engaging the engagement hole 71.

  Further, the door-end packings 91 and 91 are fitted to the vertical frames 11 and 11 in the same manner as described above at the free end side of the open / close panel 6 and the corresponding end of the movable panel 1 on the end side.
