Description

The present invention relates to a sliding wall having a partition panel movable along a ceiling rail.

As this type of sliding wall, a plurality of partition panels are movably suspended and supported on the ceiling rail, and the partition panels are positioned between a use position arranged parallel to the ceiling rail and a predetermined standby position. There is known a device that can be slid between them (see Patent Document 1, for example).

In such a sliding wall, in order to ensure safety and sound insulation at the position where it is used, pressure contact bodies are provided at the upper and lower ends of the panel body suspended on the ceiling rail so that they can be pushed back. Various types have been developed in which these pressing members protrude at the position of use and are pressed against the lower surface of the ceiling rail and the floor surface facing each other.

By the way, the panel main body of such a partition panel is a hollow body in which a frame is arranged on the periphery of parallel face plates, and the inner space thereof, that is, the inner space formed between the face plates surrounded by the frames contains the components of the pressing member driving means for causing the upper and lower pressing members to project and retract.

Therefore, even if there is a desire to make the face plate a transparent glass plate to make the panel body translucent, or to fill the space between the face plates with a functional material to improve sound insulation and sound absorption, There is a problem that it is difficult to meet the demand because the component parts of the pressure contact body driving means arranged in the space become a hindrance.

For this reason, with respect to the pressure contact mechanism 11 above, the same or corresponding portions as those of the pressure contact mechanism 11 below are denoted by the same reference numerals, and descriptions thereof are omitted.

Each of the partition panels 3 described above is used when the upper press-contact member 6B moves upward toward the ceiling surface Cea in the intersecting posture (FIGS. 3 to 5) in which the panel main body 5 is not parallel to the ceiling rail 2. 18, which preferentially comes into contact with the lower surface 2a of the ceiling rail 2 to inhibit contact of the pressure contact body 6B with the ceiling surface Cea, and the bottom frame 35 at two locations across the longitudinal center of the bottom frame 35.

It is fixed to the top wall 81 so as to sandwich it. The separation distance between both projections 161 is set to a value that allows the upper pressing body 6B to contact only the lower surface 2a of the ceiling rail 2 when it moves upward.

As shown in FIGS. 9, 10, 12 and 14 to 17, both grounding bodies 19 are attached to the bottom frame 35, respectively, and their lower ends are higher than the floor surface F and in the immersed state. It is positioned so as to be lower than the lower end of the pressure contact body 6A on the lower side. The bottom wall 71 of the lower press-contact body 6A is formed with a passage window 71a for allowing the grounding bodies 19 to pass therethrough.

As shown in FIGS. 1 to 4 and 6, the door panel 4 includes a pair of glass plates 163 spaced apart in the thickness direction and a frame interposed between the peripheral edges of the glass plates 163. 165 , and a peripheral edge member 167 that holds the frame 165 and 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 connecting the lower ends of the standing frames 169 and 171, and a top frame 175 connecting the upper ends of the standing frames 169 and 171. The right standing frame 171 is hinged to the right stationary frame 1 via hinges 177 . A door lock mechanism 179 having a handle 181 is held on the left standing frame 169 . A door frame 183 for receiving the pivot end of the door panel 4 is attached to the right edge of the rightmost partition panel 3 .

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

1 and 2 show a state in which all the partition panels 3 are arranged parallel to the ceiling rail 2 and 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 recess 1x provided on the left fixed frame 1, and the ridge 39a of the adjacent partition panel 3 is fitted. 39a and recessed portion 47a are fitted together. Also, the press-contact members 6A and 6B of each partition panel 3 protrude and are press-contacted with the lower surface 2a of the ceiling rail 2 and the floor surface F. As shown in FIG. Therefore, most of the spaces formed between the building walls W are partitioned by transparent sliding walls SW composed of glass plates 25 . Since the door panel 4 can be opened and closed even in this state, it is possible to freely enter and exit the partitioned space.

3 and 4, first, the door panel 4 is opened, and the operation part 10 of the rightmost partition panel 3 is operated to pressure-contact the partition panel 3. The bodies 6A and 6B are immersed. As a result, the partition panel 3 can be turned horizontally around the single suspension rod 67, and can take a crossed posture orthogonal to the ceiling rail 2, for example. After that, when the operation part 10 provided on the right upright frame 33 of the next partition panel 3 is operated to retract the press-contact members 6A and 6B of the partition panel 3, this partition panel 3 is also in the crossed posture. can be done. By repeating this operation, it is possible to realize an open state in which all partition panels 3 are in a crossed posture perpendicular to the ceiling rails 2 . When it is desired to fix each partition panel 3 in the open state, each partition panel 3 is operated to protrude the press contact members 6A and 6B. On the other hand, when it is desired to move the partition panel 3 further in the thickness direction from the open state and put it away near the building wall, each partition panel 3 can be moved while the pressure contact members 6A and 6B are retracted. FIG. 5 shows the retracted state in which the partition panels 3 are put away.

Next, the protruding and retracting motion of the pressure contact members 6A and 6B in each partition panel 3 will be described.

FIGS. 7, 11, 13(a), 14 and 15 show the state in which the pressure contact bodies 6A and 6B are retracted into the bottom frame 35 and the top frame 37, respectively. In this retracted state, the operating lever 91 of the operating section 10 is held at the retracted position shown in FIG. there is When the operation lever 91 is rotated from this recessed state to the projecting position as shown in FIG. , and the corresponding pressure bodies 6A and 6B project due to the action of the pressure contact mechanism 11. As shown in FIG. Here, the operation of the lower pressing mechanism 11 will be described as follows. When the operation lever 91 is rotated from the retracted position to the projected position, the transmission rod 12 moves downward, and the movement of the transmission rod 12 is converted by the second link mechanism 16 into leftward movement of the connecting bar 14 . . When the connecting bar 14 moves to the left, the movement of the connecting bar 14 is converted by the first link mechanism 15 into downward projecting movement of the pressure body 6A. The 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 terminal position (T), but the pressure contact body 6A contacts the floor surface F before the connecting bar 14 reaches the terminal position (T). locked. Therefore, the amount of movement of the connecting bar 14 after the pressure contact member 6A is pressed against the floor surface F is absorbed by the compression spring 103 of the motion absorbing mechanism 95 being compressed. In other words, the pressure body 6A is elastically pressed against the floor surface F by the repulsive force of the compression spring 103. As shown in FIG. 10, 16 and 17 show the state in which the pressure member 6A is pressed against the floor surface F. FIG.

The pressure contact mechanism portion 11 described above incorporates the assist mechanism 17 so that the operating force of the operation lever 91 of the operation portion 10 can be reduced. Specifically, when the operating lever 91 is at the retracted 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. 18(a). maintained 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 at one stop position (P) by the traction force of the tension spring 141. is in a state where it does not affect the connecting bar 14 . When the operating lever 91 is rotated toward the projecting position from this state, the connecting bar 14 first moves to the left and the joint pin 159 presses the rotating body 139 clockwise. Rotating body 139 starts rotating clockwise from one stop position (P), and when traction axis 0 of tension spring 141 passes through point (Q) shown in FIG. acts as a force to positively rotate the rotor 139 in the clockwise direction. Therefore, the joint pin 159 is urged leftward in FIG. 18 by the rotating body 139 which is positively rotated by the pulling force of the tension spring 141, and the connecting bar 14 is pulled leftward. As a result, the operating force applied to the operating lever 91 is reduced. (c) of FIG. 18 shows a state in which the connecting bar 14 has moved to the left until it reaches the terminal position (T). does not act on the connecting bar 14.

The operation of the upper pressure contact mechanism portion 11 conforms to the operation of the lower pressure contact mechanism portion 11 described above.

According to the structure of the sliding wall described above, all the components of the pressing member driving means 7 are arranged along the frame member 9, so that the internal space of the partition panel 3 can be effectively utilized. That is, in this embodiment, the face plate 8 is mainly composed of a transparent glass plate 25, and the partition panel 3 is made translucent. Then, the area of the glass plate 25 can be expanded without difficulty.

In addition, the pressure contact mechanism 11, which has many components, is housed in the bottom frame 35 and the top frame 37, and the operation part 10 provided on one of the erecting frames (right erecting frame 33) is attached to the erecting frame 33 for transmission. Since the force is transmitted to each pressure contact mechanism 11 by the rod 12, the space inside the frame 9 can be opened without difficulty.

Since the pressure contact mechanism portion 11 is provided with the assist mechanism 17, the pressure contact 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. can be improved.

By devising the relative positions of the rotating body 139 and the tension spring 141, the assist mechanism 17 applies the pulling force of the tension spring 141 to the connecting bar 14 only during the operation. A clear operating force reduction effect can be obtained.
