The upper pressure contact mechanism portion 11 housed in the top frame 37 is for causing the upper pressure contact body 6B to perform a recessing operation, and has a configuration in which the lower pressure contact mechanism portion 11 described above is turned upside down. .. Therefore, the description of the upper pressure contact mechanism portion 11 will be omitted by assigning the same reference numerals to the same or corresponding portions as the lower pressure contact mechanism portion 11.

In each of the partition panels 3 described above, when the upper pressure welding body 6B moves upward toward the ceiling surface Cea in an intersecting posture (FIGS. 3 to 5) in which the panel body 5 is not parallel to the ceiling rail 2. The upper movement prohibition element 18 that preferentially contacts the lower surface 2a of the ceiling rail 2 to prevent the pressure contact body 6B from contacting the ceiling surface Cea, and the bottom frame 35 are provided at two locations sandwiching the center in the longitudinal direction. It includes a grounding body 19.

As shown in FIGS. 15 and 17, the upper movement prohibiting element 18 has a width smaller than the width of the groove 21a of the ceiling rail 2 on both sides of the suspension rod in the upper pressure welding body 6B, and the upper end thereof is the upper end of the upper pressure welding body 6B.

The separation distance between the two protrusions 161 is set to a value that can come into contact with only the lower surface 2a of the ceiling rail 2 when the upper pressure contact body 6B moves upward.

Both grounding bodies 19 are attached to the bottom frame 35, respectively, as shown in FIGS. 9, 10, 12, and 14 to 17, and the lower end thereof is higher than the floor surface F and is in an immersive state. It is positioned so as to be lower than the lower end of the lower pressure welding body 6A. A passage window 71a for passing these grounding bodies 19 is formed on the bottom wall 71 of the lower pressure welding body 6A.

As shown in FIGS. 1 to 4 and 6, the door panel 4 is formed by a pair of glass plates 163 arranged at intervals in the thickness direction and a frame body interposed between the peripheral edges of the glass plates 163. It includes a 165, a frame body 165, and a peripheral member 167 that includes the peripheral edge of the glass plate 163.

The frame body 165 includes left and right standing frames 169 and 171, a bottom frame 173 that connects the lower ends of the standing frames 169 and 171 to each other, and a top frame 175 that connects the upper ends of the standing frames 169 and 171 to each other. The right upright frame 171 is hinged to the right fixed frame 1 via a hinge 177. Further, the left standing frame 169 holds a door lock mechanism 179 provided with a handle 181. A door frame 183 for receiving the rotating end of the door panel 4 is attached to the right edge of the partition panel 3 arranged on the far right side.

Next, the operation of this sliding wall will be described.

1 and 2 show a state in which all the partition panels 3 are arranged parallel to the ceiling rail 2 so as to be closely adjacent to each other and the door panel 4 is closed. In this state, the ridge 39a provided on the left standing frame 31 of the leftmost partition panel 3 fits into the recessed portion 1x provided on the left fixed frame 1, and the ridges of the adjacent partition panels 3 are fitted. The 39a and the recessed portion 47a are fitted to each other. Further, the pressure contact bodies 6A and 6B of each partition panel 3 project and are pressure-welded to the lower surface 2a and the floor surface F of the ceiling rail 2. Therefore, most of the space formed between the building walls W is partitioned by a transparent sliding wall SW composed of a glass plate 25. Even in this state, since the door panel 4 can be opened and closed, it is possible to freely enter and exit between the partitioned spaces.

When the sliding wall SW is set to the open state shown in FIGS. 3 and 4, the door panel 4 is first opened, and the operation unit 10 of the partition panel 3 located on the far right is operated to press-weld the partition panel 3. Immerse the bodies 6A and 6B. As a result, the partition panel 3 can be turned horizontally around a single suspension rod 67, and can be in an intersecting posture orthogonal to the ceiling rail 2, for example. After that, when the operation unit 10 provided on the right standing frame 33 of the next partition panel 3 is operated to immerse the pressure welding bodies 6A and 6B of the partition panel 3, the partition panel 3 is also placed in the crossing posture. Can be done. By repeating this operation, it is possible to realize an open state in which all the partition panels 3 are in an intersecting posture orthogonal to the ceiling rail 2. When it is desired to fix each partition panel 3 in the open state, each partition panel 3 may be operated to project the pressure welding bodies 6A and 6B. On the other hand, when it is desired to further move the partition panel 3 in the thickness direction from the open state and put it away in the vicinity of the building wall, each partition panel 3 may be moved while the pressure contact bodies 6A and 6B are immersed. FIG. 5 shows a retracted state in which each partition panel 3 is tidied up.

Next, the sinking operation of the pressure contact bodies 6A and 6B in each partition panel 3 will be described.

7, FIG. 11, FIG. 13A, FIGS. 14 and 15, show a state in which the pressure contact bodies 6A and 6B are immersed in the bottom frame 35 and the top frame 37, respectively. In this immersive state, the operation lever 91 of the operation unit 10 is held at the immersive position shown in FIG. 13 (a), and the pressure contact bodies 6A and 6B are separated from the lower surface 2a and the floor surface F of the ceiling rail 2. There is. When the operating lever 91 is rotated from this immersed state to the protruding position as shown in FIG. 13 (b), the upper and lower transmission rods 12 move in opposite directions, and the movement of the transmission rod 12 moves to the pressure contact mechanism portion 11. The corresponding pressure welding bodies 6A and 6B project by the action of the pressure welding mechanism portion 11. Here, the operation of the lower pressure welding mechanism portion 11 will be described as follows. When the operating lever 91 is rotated from the immersion position to the protruding position, the transmission rod 12 moves downward, and the movement of the transmission rod 12 is converted into the movement to the left of the connecting bar 14 by the second link mechanism 16. .. When the connecting bar 14 moves to the left, the movement of the connecting bar 14 is converted into a downward projecting motion of the pressure contact body 6A by the first link mechanism 15, and is provided at the lower end of the pressure contact body 6A. The close contact member 73 is pressed against the floor surface F. At this time, the connecting bar 14 moves from the predetermined initial position (S) to the predetermined end point position (T), but the pressure contact body 6A comes into contact with the floor surface F before the connecting bar 14 reaches the end point position (T). Is locked. Therefore, the movement of the connecting bar 14 after the pressure contact body 6A is pressure-contacted with the floor surface F is absorbed by the compression spring 103 of the motion absorbing mechanism 95. In other words, the pressure contact body 6A is elastically pressed against the floor surface F by the repulsive force of the compression spring 103. 10, 16 and 17 show a state in which the pressure contact body 6A is pressure-welded to the floor surface F.

The pressure welding mechanism portion 11 described above incorporates an assist mechanism 17, so that the operating force of the operating lever 91 of the operating portion 10 can be reduced. Specifically, when the operating lever 91 is in the immersion position, the connecting bar 14 is stopped at the initial position (S), and the rotating body 139 of the assist mechanism 17 is shown in FIG. 18A. It is held in a state. That is, the traction axis L0 of the tension spring 141 is located above the fulcrum 143, and the rotating body 139 is locked to one stop position (P) by the traction force of the tension spring 141, and the traction force of the tension spring 141. Is in a state that does not affect the connecting bar 14. When the operating lever 91 is rotated toward the protruding position from this state, the connecting bar 14 first moves to the left and the joint pin 159 presses the rotating body 139 in the clockwise direction. The rotating body 139 starts rotating clockwise from one stop position (P), and when the traction axis 0 of the tension spring 141 passes through the thought point (Q) shown in FIG. 18 (b), the traction force of the tension spring 141 Acts as a force that positively rotates the rotating body 139 in the clockwise direction. Therefore, the joint pin 159 is urged to the left in FIG. 18 by the rotating body 139 that actively rotates by the traction force of the tension spring 141, and the connecting bar 14 is pulled to the left. As a result, the operating force applied to the operating lever 91 is reduced. FIG. 18C shows a state in which the connecting bar 14 has moved to the left to the end point position (T). In this state, the rotation of the rotating body 139 is locked by a stopper (not shown), and the traction force of the tension spring 141. Does not act on the connecting bar 14.

The operation of the upper pressure welding mechanism portion 11 is based on the operation of the lower pressure welding mechanism portion 11 described above.

According to the structure of the sliding wall described above, since all the components of the pressure contact body driving means 7 are arranged along the frame body 9, the internal space of the partition panel 3 can be effectively used. That is, in this embodiment, the face plate 8 is mainly composed of the transparent glass plate 25, and the partition panel 3 is made transparent, but the components of the pressure welding body driving means 7 are arranged as described above. Then, the area of the glass plate 25 can be expanded without difficulty.

Further, the pressure contact mechanism portion 11 having many components is housed in the bottom frame 35 and the top frame 37, and the operation portion 10 provided on one of the standing frames (right standing frame 33) is attached to the standing frame 33 for transmission. Since the rod 12 transmits the pressure to each pressure contact mechanism portion 11, the space inside the frame body 9 can be opened without difficulty.

Since the pressure welding mechanism portion 11 includes the assist mechanism 17, the pressure welding bodies 6A and 6B can be reliably pressed against the floor surface F and the lower surface 2a of the ceiling rail 2 without requiring a large operating force, and workability can be achieved. Can be improved.

Then, the assist mechanism 17 devises the relative position between the rotating body 139 and the tension spring 141 so that the traction force of the tension spring 141 acts on the connecting bar 14 only during the operation. A clear effect of reducing the operating force can be obtained.

The present invention is not limited to the embodiments described above.

For example, the face plate is not limited to the one mainly composed of a transparent glass plate as in the above-described embodiment. When the present invention is applied when the face plate is mainly composed of an opaque plate material, the space between the face plates can be widened, so that the space is filled with a functional material to provide sound insulation and sound absorption. It becomes possible to easily add such performance.

In the above embodiment, the transmission rod is arranged along the inner side surface of the upright frame, and the transmission rod is hidden by the edge member provided on the face plate side, but the transmission rod is accommodated in the upright frame. May be good.

Of course, the configuration of the pressure contact mechanism portion is not limited to that according to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

Further, the invention according to claim 1 includes an invention not provided with an assist mechanism. Of course, when the assist mechanism is provided, its configuration is not limited to that according to the above-described embodiment.
