DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be realized, and are not intended to limit the scope of the present invention.

[0019] <Embodiment 1> Fig. 1 shows a fixing device A (without a pusher member advanced) according to a first embodiment of the present invention, with Fig. 1(a) being a left side view, Fig. 1(b) being a front view transparently showing the internal structure, and Fig. 1(c) being a cross-sectional view taken along line XX in Fig. 1(b). Fig. 2 shows the same fixing device A (with a pusher member advanced) with Fig. 2(a) being a left side view, Fig. 2(b) being a front view, and Fig. 2(c) being a cross-sectional view). The fixing device A of this embodiment is a device for driving a pressure contact device for a partition panel in order to fix the movable partition panel when it is installed. a main body 1 including a motion conversion unit that converts a horizontal pressing force received by a lateral slide unit 12 into a vertical motion; a shaft 18 which is a connecting member connected to the motion conversion unit and extending in the vertical direction; a shaft 18 as a connecting member, a push-in member 14 detachably and rotatably connected thereto and advancing in a vertical direction; It is equipped with: The main body 1 is a housing part 11; a horizontal slide portion 12 movably attached to the housing portion 11 so as to be displaced in a horizontal direction; a vertical slide portion 13 movably attached to the housing portion 11 so as to be displaced in the vertical direction; a spring (first biasing means) S2 that generates a biasing force to resist the advancement of the push-in member 14; a rotating cam member 15 that is rotatably attached to the housing portion 11 and that, by its rotation, converts the horizontal displacement of the horizontal slide portion 12 into the vertical displacement of the vertical slide portion 13, thereby functioning as a motion conversion portion; a stopper 16 that restricts the rotation of the rotary cam member 15 from returning when the push-in member 14 is in the advanced state; a release member 17 that releases the restriction of the stopper 16 on the rotating cam member 15; It is equipped with:

[0020] The housing 11 is a box-shaped member that houses the various components. The housing 11 of this embodiment is made up of a box-shaped member 111 and a cover member 112. The box-shaped member 111 has: a guide groove that holds the lateral slide portion 12 so that it can slide horizontally and protrude from the side surface; a guide groove that holds the vertical slide portion 13 so that it can slide in the vertical direction; a guide groove that holds the lateral slide stopper portion 171 so that the lateral slide stopper portion 171 can slide horizontally and protrude from the side surface; Recesses are formed to hold the springs S2 and S3. The cover member 112 is a plate-like member, and is joined to the box-shaped member 111 (any joining method may be used, such as screwing) after the components described below are assembled to the box-shaped member 111. The housing 11 is also provided with shaft members or bearings that rotatably hold the rotary cam member 15 and the stopper 16, respectively. Here, the housing unit 11 is shown as a box-shaped member as an example, but the present invention is not limited to this, and the housing unit may be any member that can hold each member in an operable manner, such as a frame-shaped member.

[0021] The horizontal slide portion 12 is a member that is provided so as to be able to appear and disappear from one side surface of the housing portion 11 (the left side surface in FIG. 1(b)), and is a member that abuts against the rotating cam member 15 to rotate the rotating cam member 15. More specifically, as will be explained later, the horizontal slide portion 12 is provided so as to protrude from the surface where adjacent movable partition panels come into contact with each other, and when the adjacent movable partition panels come into contact with each other, the horizontal slide portion 12 is pushed and slides (pushed in), causing the rotating cam member 15 to rotate. Figure 1 shows the state in which the lateral slide portion 12 protrudes from the housing portion 11 and does not apply any rotational force to the rotating cam member 15, and Figure 2 shows the state in which the lateral slide portion 12 is pushed and slides, causing the rotating cam member 15 to rotate. The horizontal slide portion 12 has cam contact portions 121 on both sides (on both sides in the thickness direction, on the front side and rear side in front view (FIG. 1(b))), and the cam contact portions 121 rotate the rotating cam member 15. The tip portion of the cam contact portion 121 (the portion that comes into contact with the rotating cam member 15) is formed in a curved (round) shape, which ensures smooth contact and sliding with the rotating rotating cam member 15. Although the above-mentioned shape is used as an example here, the lateral sliding portion of the present invention is not limited to this, and the lateral sliding portion can be of any shape that can move when pressed and rotate the rotating cam member.

[0022] The rotating cam member 15 is rotatably attached to the housing portion 11, rotates when pressed by the horizontal slide portion 12, and presses the vertical slide portion 13 downward in accordance with this rotation. The rotating cam member 15 of this embodiment has two plate-like members with a basic fan shape on both sides (the front side and the back side in a front view (FIG. 1(b))) (see FIGS. 1(b) and (c)), and these two fan-shaped plate members are connected to each other by a shaft member. The shaft member is the rotation axis of the rotating cam member 15. FIG. 3 is an enlarged view of the vicinity of the location where the rotary cam member 15 is arranged in FIG. 1(b). The fan-shaped plate material of the rotating cam member 15 has a horizontal contact portion 151 that contacts the horizontal slide portion 12 on one radial side of the fan shape, and a vertical contact portion 152 that contacts the vertical slide portion 13 on the other radial side of the fan shape, and is configured to displace the vertical slide portion 13 vertically by the rotational force generated by the horizontal displacement of the horizontal slide portion 12. The vertical contact portion 152 is formed as a convex portion, and its tip portion (the portion that comes into contact with the vertical slide portion 13) is formed in a curved (round) shape, which ensures smooth contact and sliding of the rotating rotating cam member 15 against the vertical slide portion 13. An engaging recess 153 that engages with a stopper 16 described below is formed on the side of the lateral contact portion 151 of the sector-shaped plate material of the rotating cam member 15. While the above-mentioned shape is used as an example here, the rotating cam member of the present invention is not limited to this, and the rotating cam member can have any shape that allows the vertical sliding portion to be displaced in the vertical direction by the rotational force generated by the horizontal displacement of the lateral sliding portion. However, a fan shape is preferable because it reduces unintended interference with the operation of the stopper described below. The contact between the rotating cam member 15 and the horizontal slide portion 12 or the vertical slide portion 13 is not limited to direct contact with each other, but may be indirect contact via another member.

[0023] The vertical slide portion 13 is a member that is movably attached to the housing portion 11 so as to be displaceable in the vertical direction, and is pushed down as the rotating cam member 15 rotates. The vertical slide portion 13 has a flat portion on its upper surface that comes into contact with the vertical contact portion (protrusion) 152 of the rotating cam member 15. The shaft 18 is connected to the lower surface side of the vertical slide portion 13. A spring (first biasing means) S2 through which a shaft 18 is passed is provided between the vertical slide portion 13 and the housing portion 11, and the vertical slide portion 13 is biased upward by the spring S2 (as a result, the rotating cam member 15 and the horizontal slide portion 12 are also biased in a direction that causes the horizontal slide portion 12 to protrude). Although the above-mentioned shape is used as an example here, the vertical slide portion of the present invention is not limited to this, and the vertical slide portion can be of any shape that can push the push-in member downward when pressed by the rotating cam member.

[0024] The shaft 18, one end of which is connected to the vertical slide portion 13, extends to the outside of the housing portion 11 through an insertion hole (not shown) provided in the housing portion 11, and the other end is connected to the pushing member 14 in a detachable and rotatable or swingable manner. The shaft 18 has an engagement portion 181 at the other end (the side that engages with the push-in member). In this embodiment, the engagement portion 181 is formed as a pin member that functions as a rotation axis. The engagement portion 181, which is a pin member, is arranged so that its axial direction is perpendicular to the front and back surfaces of the partition panel (perpendicular to the plane of the paper in FIG. 1(b)) when the fixing device A is attached to the partition panel. Here, a shaft 18 (rod-shaped member) is used as an example of the connecting member, but the connecting member of the present invention is not limited to this, and the connecting member can have any shape that can connect the vertical sliding portion and the pushing member.

[0025] The pushing member 14 is connected to the shaft 18 and moves up and down in response to the vertical movement of the vertical sliding portion 13 . 5A and 5B are diagrams showing the pushing member 14, with FIG. 5A being a left side view, FIG. 5B being a front view shown transparently so that the internal structure can be seen, and FIG. 5C being a top view. The pusher member 14 of this embodiment is basically a rectangular cylindrical member having a bottom surface, and has a spring S1 disposed therein. The spring S1 is disposed between the bottom surface of the pusher member 14 and a piston member 141 disposed inside the pusher member 14 so as to be able to slide up and down, and the shaft 18 is detachably and rotatably connected to the piston member 141. As a result, as the shaft 18 advances downward, the pushing member 14 also moves downward, and even after the pushing member 14 comes into contact with another member and cannot move any further down (the pressing device described later comes into contact with the floor surface), the spring S1 contracts, allowing the shaft 18 (and the piston member 141) to be pushed further in while maintaining a compressive force. An opening 142 is formed on one side of the pushing member 14 (see FIG. 5(a)) to receive the shaft 18 and its engaging portion 181. The "one side" refers to the side from which the horizontal sliding portion 12 protrudes, and is the edge side when attached to a movable partition panel (the same applies below). In this embodiment, the opening 142 is an inverted T-shaped hole when viewed from the one side (FIG. 5(a)). The opening 142 communicates with a shaft insertion hole 143 formed on the upper surface of the pushing member 14 (the side facing the main body 1), allowing the shaft 18 to be attached and detached from the one side. The shaft insertion hole 143 on the upper surface of the pushing member 14 allows the shaft 18 to pass through when attached, but the engaging portion 181 is formed so that it cannot be inserted. Therefore, when the shaft 18 is attached to the pushing member 14 (as shown in FIG. 5), the shaft 18 cannot be removed from the pushing member 14 in the vertical direction. A guide groove 1411 that receives the shaft 18 and its engaging portion 181 is formed inside the piston member 141. The guide groove 1411 receives the shaft 18 and its engaging portion 181 from one side surface, and is formed as a groove (a groove that is approximately L-shaped (inverted L-shaped) in FIG. 4) that moves the shaft 18 and its engaging portion 181 in the horizontal direction (the direction along which the lateral slide portion 12 appears and disappears) to approximately the center of the piston member 141, and then moves the shaft 18 and its engaging portion 181 in the vertical direction from there. The guide groove 1411 forms an opening (an opening having an inverted T shape similar to the opening 142) on one side of the piston member 141 that receives the shaft 18 and its engagement portion 181. Also, a shaft insertion hole is formed on the upper surface side of the piston member 141 (the side facing the main body 1), and this shaft insertion hole faces and communicates with the shaft insertion hole 143 formed on the upper surface of the pushing member 14. The shaft insertion hole of the piston member 141 allows the shaft 18 to pass through in the attached state, but the engagement portion 181 is formed so that it cannot be inserted. Therefore, in the positional relationship in which the shaft 18 is attached to the piston member 141 (the state shown in FIGS. 1 and 2), the shaft 18 is configured to not come out of the piston member 141 in the vertical direction. As shown in FIG. 5(c), the shaft insertion hole 143 formed in the upper surface of the pushing member 14 is formed so as to extend beyond the shaft 18 (extending upward beyond the shaft 18 in FIG. 5(c)) in the positional relationship in which the shaft 18 is attached to the pushing member 14 (the state of FIG. 5). The shaft insertion hole formed in the upper surface of the piston member 141 is also formed so as to extend beyond the shaft 18. As shown in FIG. 5(b), a groove 1412 is formed in a tapered shape from the position in the upper surface of the piston member 141 where the shaft insertion hole extends beyond the shaft 18 toward the lower end of the inverted L-shaped guide groove 1411. These insertion holes and grooves function as relief portions to receive the shaft 18, which tilts relatively (performs a swiveling motion) when the pushing member 14 rotates. With the above configuration, when the shaft 18 is attached to the pushing member 14 (piston member 141) (as shown in Figures 1 and 2), the pushing member 14 is rotatable relative to the main body 1, and therefore "is equipped with a rotation mechanism that enables the pushing member to oscillate or rotate relative to the main body." The rotation mechanism is "composed of a rotation shaft member (engagement portion 181) formed on the connecting member (shaft 18) and a receiving portion (guide groove 1411) formed on the pushing member (piston member 141) that rotatably receives the rotation shaft member (engagement portion 181)." Furthermore, "the connecting member (shaft 18) has a pivot shaft member (engagement portion 181) at the bottom, and an opening 142 for receiving the pivot shaft member (engagement portion 181) is formed on the side (one side) of the pushing member facing the protruding direction." Although the pusher member has the above-mentioned shape, the pusher member of the present invention is not limited to this, and the pusher member may have any shape (e.g., cylindrical, etc.) that has the above-mentioned function. Similarly, the piston member may have any shape (e.g., columnar, etc.) that has the above-mentioned function.

[0026] The stopper 16 is rotatably attached to the housing 11, and is swingable between a restricting position (the state in FIG. 2) where the rotation of the rotating cam member 15 is restricted from returning, and a non-restricting position (the state in FIG. 1). The stopper 16 of this embodiment is basically a plate-shaped member (rod-shaped when viewed from the front (FIG. 1(b))) and is rotatably attached to the rotation shaft above the center when viewed from the front. As a result, in a free state, it is configured to face vertically due to its own weight. The upper side of the rotation axis of the stopper 16 constitutes an upper convex portion (engagement portion) 161 (see FIG. 3), and the lower side constitutes a cam engagement portion 162. The upper protrusion 161 comes into contact with an engaging projection 1711 of the lateral slide stopper portion 171, which will be described below, and when the lateral slide stopper portion 171 is in the protruding position, the stopper 16 is rotated to the restriction release position (the state shown in FIG. 1(b)). The tip (upper portion) of the upper protrusion 161 is formed in an arc shape when viewed from the front (FIG. 3), which allows for smooth engagement with the lateral slide stopper portion 171, which will be described below. As shown in FIG. 2(b), when the stopper 16 is in the vertical position (restricted position), the cam engaging portion 162 engages with the engaging recess 153 of the rotating cam member 15, and restricts the rotating cam member 15 from rotating back. Although the stopper of the present invention is exemplified by the above-mentioned shape, the stopper of the present invention is not limited to this, and the stopper can have any shape that has the above-mentioned function.

[0027] The release member 17 releases the restriction of the stopper 16 on the rotating cam member 15, and includes a lateral slide stopper portion 171 movably attached to the housing portion 11 so as to be displaced horizontally, and a spring (second biasing means) S3 that biases the lateral slide stopper portion 171. As will be explained later, the lateral slide stopper portion 171 is arranged in the same manner as the lateral slide portion 12 so that it protrudes from the surface where adjacent movable partition panels come into contact with each other, and when adjacent movable partition panels come into contact with each other, the lateral slide stopper portion 171 is pushed and slides. Figure 1(b) shows a state in which the lateral slide stopper portion 171 protrudes from the housing portion 11 and does not restrict rotation of the rotating cam member 15, and Figure 2(b) shows a state in which the lateral slide stopper portion 171 is pressed and slides, restricting rotation of the rotating cam member 15. As can be seen from FIG. 1( b ), the amount of protrusion of the lateral slide stopper portion 171 is configured to be smaller than the amount of protrusion of the lateral slide portion 12 . The horizontal slide stopper portion 171 is basically a rectangular pillar-shaped member, and has an engagement protrusion 1711 (see FIG. 3) formed at a position facing the stopper 16. When the horizontal slide stopper portion 171 is in the protruding position, the engagement protrusion 1711 engages with an upper convex portion (engagement portion) 161 of the stopper 16, causing the stopper 16 to rotate to the release position. As the horizontal slide stopper portion 171 is pushed in, the engagement of the engagement protrusion 1711 with the upper convex portion 161 is released, and as a result, the stopper 16 faces vertically (moves to the restriction position) due to its own weight. The spring (second biasing means) S3 is provided between the housing 11 and the horizontal slide stopper portion 171 and biases the horizontal slide stopper portion 171 in a direction that causes it to protrude. The elastic force of the spring S3 is smaller than the elastic force of the springs S1 and S2. More specifically, the movable partition panel is configured so that it does not move with the elastic force of the four springs S3. Two fixing devices A are provided, one above the other, on the contact surface between the movable partition panels. That is, fixing devices A are provided at the top and bottom of each of the side surfaces that are both ends in the moving direction of the movable partition panel. Therefore, when adjacent movable partition panels come into contact with each other, the four horizontal slide stopper portions 171 are pressed in. At this time, the four horizontal slide stopper portions 171 are forced to return due to the elastic force of each spring S3, preventing the movable partition panel from moving. This means that "the movable partition panel is configured so that it does not move with the elastic force of the four springs S3." As described above, the release member 17 is configured so that "when the lateral slide stopper portion is slid against the biasing force of the second biasing means, the stopper is positioned at the restricted position, and when the lateral slide stopper portion is slid by the biasing force, the stopper is positioned at the unrestricted position." Although the above configuration is used as an example here, the release member 17 of the present invention is not limited to this, and the release member 17 can have any configuration that has the above function.

[0028] A series of operations of the fixing device A having the above configuration will be outlined below. When the left side of the fixing device A in Figure 1(b) (the left side is used here for convenience of explanation, and depending on the installation situation of the fixing device A, it could be any direction such as the right side, top, or bottom) comes into contact with another component (specifically, the adjacent movable partition panel), first the horizontal sliding portion 12 is pushed in. As the horizontal slide portion 12 is pushed in, the rotary cam member 15 rotates, causing the vertical slide portion 13 and the pushing member 14 to advance downward. As the slide further advances, the lateral slide stopper portion 171 begins to be pushed in. As the lateral slide stopper portion 171 is pushed in, the engagement of the engagement protrusion 1711 of the lateral slide stopper portion 171 with the upper convex portion 161 of the stopper 16 is released, and the stopper 16 comes into a state of following (leaning against) the arc of the fan shape of the rotating cam member 15. At this time, because the rotating cam member 15 is fan-shaped, unintended interference with the rotation of the rotating cam member 15 due to contact of the stopper 16 is prevented. When the horizontal sliding portion 12 is pushed in completely (when it comes into close contact with the adjacent movable partition panel), the vertical sliding portion 13 and the pushing member 14 reach their most advanced positions. Also, the cam engaging portion 162 of the stopper 16 engages with the engaging recess 153 of the rotating cam member 15 (the state shown in FIG. 2(b)). This restricts the rotation of the rotating cam member from returning, and therefore restricts the force with which the horizontal sliding portion 12 is pushed back by the springs S1 and S2 (and the coil spring S4). In this manner, the fixing operation by the fixing device A is carried out.

[0029] Next, as a release operation for the fixed state, when the adjacent movable partition panel begins to move, the horizontal slide stopper portion 171 first begins to slide due to the biasing force of the spring S3. At this stage, the stopper 16 is in the restricted position, so the rotating cam member 15 cannot rotate, and therefore the horizontal slide portion 12, the vertical slide portion 13, and the push-in member 14 do not move at this stage either. As the lateral slide stopper portion 171 slides, the engaging projection 1711 of the lateral slide stopper portion 171 engages with the upper projection 161 of the stopper 16, rotating the stopper 16 to the release position, causing the rotating cam member 15 to rotate due to the biasing force of springs S1 and S2, and accompanying this, the lateral slide portion 12 also slides in the protruding direction. In addition, the vertical slide portion 13 and the pushing member 14 also move upward due to the biasing force of springs S1 and S2. When the adjacent movable partition panels move away from each other, the state shown in Figure 1 is restored. In this manner, the fixing device A performs the fixing release operation.

[0030] As described above, according to the fixing device A of this embodiment, the fixing and releasing operations are automatically performed as the movable partition panel moves, so that no separate operation for fixing or releasing the panel is required. Furthermore, according to the fixing device A of this embodiment, the use of a rotating cam member allows the device to be made smaller. The device of Patent Document 1 uses a first sliding member with an inclined guide hole 11c, which tends to increase the dimension in the left-right direction (the sliding direction of the first sliding member) when viewed from the front. In addition, the rod portion 33 protruding upward increases the dimension in the up-down direction (it is necessary to secure space around the rod portion 33 so as not to obstruct the operation of the rod portion 33 protruding upward). In contrast to this, the fixing device A of this embodiment uses a rotating cam member, which allows the device to be made smaller.

[0031] Furthermore, according to the fixing device A of this embodiment, as shown in FIG. 4, the shaft 18 (connecting member) is detachable from the pushing member 14, and is configured so that the shaft 18 (connecting member) can be removed from the pushing member 14 on one side (the protruding direction in which the lateral sliding portion protrudes from the main body portion). 4 and 7, the main body 1 can be removed from the edge of the partition panel (the side surfaces on both sides in the moving direction of the panel). This improves the workability of replacing the fixing device (main body) when the mechanism of the fixing device (main body) breaks down.

[0032] Furthermore, according to the fixing device A of this embodiment, a rotation mechanism is provided that enables the pushing member to rotate relative to the main body, thereby reducing the load between the members during the opening and closing operation of the movable partition panel described below (Embodiment 2).

[0033] <Embodiment 2> Next, as a second embodiment, a movable partition panel equipped with the fixing device A of the first embodiment will be outlined. Fig. 6 is a front view showing the internal structure of a movable partition panel 2 according to a second embodiment of the present invention in a transparent manner so that it can be seen. Fig. 7 shows the location where the fixing device A is installed on the lower side of the movable partition panel 2 of this embodiment (when the pushing member is not advanced), with Fig. 7(a) being a left side view and Fig. 7(b) being a front view showing a part of the internal structure in a transparent manner so that it can be seen. Fig. 8 also shows the location where the fixing device A is installed on the lower side of the movable partition panel 2 (Fig. 8(a) being a left side view and Fig. 8(b) being a front view), showing the state in which the pushing member has advanced. Fig. 9 shows the positional relationship of the fixing device A with respect to the vertical frame member 24 of the movable partition panel 2 of this embodiment, with Fig. 9(a) being a front view showing the location where the fixing device A is installed on the lower side of the movable partition panel 2, and Fig. 9(b) being a horizontal cross-sectional view of the same location.

[0034] Movable partition panel 2 is A panel body 21; A fixing device A disposed inside the panel body 21; a pressure welding device 22 that is provided so as to be movable in a vertical direction relative to the panel body 21 and is driven by a fixing device A; a hoist 23 provided on the upper part of the panel body 21; Frame members (vertical frame members 24, horizontal frame members 25) provided inside the panel body 21; The panel body 21 is provided with a sound absorbing material (or sound insulating material) 26 (represented as a mesh in FIGS. 6 and 9).

[0035] FIG. 10 is a diagram showing an outline of a movable partition 100 using the movable partition panel 2. As shown in FIG. The movable partition panel 2 is slidably suspended by a running rail 3 installed on the ceiling. The running rails 3 of the movable partition 100, the hoist 23 that is mounted so as to be able to run on the running rails 3, and the configuration of the panel body 21 can be any configuration, so explanations will be omitted here.

[0036] As shown in FIGS. 7 and 8, a pressure welding device 22 is provided at the lower end of the movable partition panel 2 so as to be retractable relative to the panel body 21. The pressure welding device 22 includes two vertically arranged wall plates 221 , a bottom surface 222 , and legs 223 . The wall panel 221 and the bottom surface 222 are basically plate-shaped members, and the legs 223 are formed of pressure-welded rubber. The wall panel 221, the bottom surface 222, and the legs 223 have width dimensions that are approximately the same as the width of the movable partition panel 2 (in the left-right direction when viewed from the front (FIG. 7(b))), and therefore, when the pressure-welding device 22 advances, the gap below the movable partition panel 2 is closed when viewed from the front. A similar pressure welding device 22 is also disposed on the upper side of the movable partition panel 2 (see FIG. 6), and therefore, when the upper pressure welding device 22 advances, the gap above the movable partition panel 2 is closed. Here, the above-mentioned configuration is used as an example of the pressure welding device 22, but the pressure welding device of the present invention is not limited to this, and the pressure welding device can be configured in any way that is movable so as to be displaced vertically relative to the panel body and can come into contact with the floor surface, etc.

[0037] A frame member is provided inside the panel main body 21 as a reinforcing member, and in the panel main body 21 of this embodiment, the frame member is formed by joining together vertical frame members 24 provided at both ends in the width direction (left and right direction when viewed from the front (Figure 6)) and horizontal frame members 25 provided at the top, bottom, and middle. As shown in FIG. 9(b), the vertical frame member 24 has both side surface portions 241 and a connecting portion 242 that connects the both side surface portions 241 together. The vertical frame member 24 is basically a member that extends in the vertical direction with the same cross-sectional shape, but at the location where the fixing device A is installed, an opening is provided in the connection portion 242 through which the main body portion 1 of the fixing device A can be inserted.

[0038] The push-in member 14 of the fixing device A is attached to the insulation displacement device 22 by being screwed onto the bottom surface 222 of the insulation displacement device 22 from the bottom side (see FIGS. 7 and 8). The main body 1 of the fixing device A has an attachment portion 19 for screwing the main body 1 to the connection portion 242 of the vertical frame member 24. The attachment portion 19 is "an attachment portion for attachment to a movable partition panel, and is an attachment portion that contacts one side of the movable partition panel (vertical frame member) (the small edge side of the movable partition panel, the side where the horizontal sliding portion protrudes from the main body)." As described above, the connection portion 242 of the vertical frame member 24 is provided with an opening through which the main body 1 of the fixing device A can be inserted. When the main body 1 is inserted into the opening from one side, The mounting portion 19 is configured to contact the connecting portion 242 around the opening from one side, and the main body 1 is attached to the movable partition panel 2 by screwing the mounting portion 19 to the connecting portion 242. Note that Figure 9(b) shows screwing of the mounting portion 19 on the upper side, with the screw located approximately in the center in the thickness direction of the movable partition panel 2, but on the lower side, the screw is screwed in at a position offset from the center in the thickness direction. The shaft 18 is located in the center in the thickness direction on the lower side, and if the screw were located in the center in the thickness direction, the shaft 18 would get in the way of access to the screw, so this prevents this. The connection structure between the main body 1 and the push-in member 14 is the same as that described in the first embodiment. The fixing device A is installed inside the movable partition panel 2 so that the horizontal slide portion 12 and the horizontal slide stopper portion 171 protrude from the side surface of the movable partition panel 2, as shown in FIG. 7(b). The fixing devices A are provided near the lower and upper ends of each of the side surfaces at both ends in the width direction (left and right direction when viewed from the front (Figure 6)) of the movable partition panel 2. In other words, four fixing devices A are basically provided per movable partition panel 2 (see Figure 6). Here, an example has been given in which the main body 1 of the fixing device A is attached to the vertical frame member 24, but the present invention is not limited to this, and the main body of the fixing device may be attached to a member that the movable partition panel appropriately has (for example, a member dedicated to attaching the main body of the fixing device).

[0039] A series of operations of the movable partition panel 2 having the above configuration will be outlined below. Note that while the fixing device and pressure welding device on the lower left side will be described here, the same concept (left-right symmetry or top-bottom symmetry) also applies to the right and upper sides. As shown in FIG. 10, when the movable partition panels 2 are moved for installation, adjacent movable partition panels 2 come into contact with each other. This contact, as explained in the first embodiment, drives the fixing device A to advance the pushing member 14 downward, which also advances downward the pressure contact device 22. When the adjacent movable partition panels 2 are brought into close contact with each other, the pressure contact device 22 comes into contact with (is pressed against) the floor surface FL as shown in Figure 8, and the fixing operation by the fixing device A is also completed. At this time, as explained in the first embodiment, due to the locking by the stopper 16, the biasing force of the springs S1 and S2 does not act to push out the horizontal sliding portion 12. Furthermore, as mentioned above, the elastic force of the spring S3 is set to be an elastic force that does not allow the movable partition panel 2 to move, and therefore the movable partition panel 2 is not moved by the horizontal sliding stopper portion 171. Therefore, when the movable partition panel 2 is released from the hand, the movable partition panel 2 will not move due to being pushed by the horizontal sliding portion 12 or the horizontal sliding stopper portion 171, and this provides excellent operability.

[0040] When removing (storing) the movable partition panel 2, the movable partition panel 2 is pulled and moved, thereby releasing the contact between adjacent movable partition panels 2. As a result, as described in the first embodiment, the fixing device A is driven and the pushing member 14 moves upward, which also causes the pressure contact device 22 to move away from the floor surface FL and return to the stored state shown in FIG.

[0041] As described above, according to the movable partition panel 2 of this embodiment, by using the fixing device A, the fixing and unlocking operations are performed automatically as the movable partition panel moves, so no separate operations are required for fixing or unlocking.

[0042] According to the movable partition panel 2 of this embodiment, the shaft 18 (connecting member) of the fixing device A is configured so that it can be removed from the pushing member 14 on one side (the protruding direction in which the horizontal sliding portion protrudes from the main body portion), and the mounting portion 19 for attaching the main body portion 1 of the fixing device A to the vertical frame member 24 is configured so that it contacts the vertical frame member 24 from one side. This allows the main body 1 to be removed from the edge of the partition panel (the side surfaces on both sides in the direction of panel movement), improving the workability of replacing the fixing device (main body) in the event of a malfunction in the mechanism of the fixing device (main body).

[0043] Furthermore, according to the movable partition panel 2 of this embodiment, as described in embodiment 1, it is equipped with a rotation mechanism that enables the pushing member 14 to rotate relative to the main body 1, thereby reducing the load between the members when the movable partition panel 2 is opened or closed. FIG. 11 is a diagram showing a state in which the pushing member 14 of the fixing device A on one side of the movable partition panel 2 is advanced, and the pushing member 14 of the fixing device A on the other side is not advanced. As can be understood from the above description of operation, when one side of the movable partition panel 2 is in contact with the adjacent movable partition panel and the other side is not in contact with the adjacent movable partition panel, as shown in FIG. 11, the pushing member 14 of the fixing device A on one side is advanced, and the pushing member 14 of the fixing device A on the other side is not advanced. In other words, the pressure welding device 22 is inclined. When the pressure welding device 22 is inclined, the pushing member 14 fixed to it is also inclined relative to the vertical. Meanwhile, since the orientation of the main body 1 fixed to the panel main body 21 remains vertical, the orientation of the pushing member 14 relative to the main body 1 changes. In contrast, according to the movable partition panel 2 of this embodiment, as described in the first embodiment, the pushing member 14 is provided with a rotation mechanism that enables the pushing member 14 to rotate relative to the main body 1, and therefore the two can rotate relative to each other to absorb any changes in the orientation of the pushing member 14 relative to the main body 1. Therefore, when the movable partition panel 2 is opened or closed, the load applied between the members is reduced.

[0044] Furthermore, since the movable partition panel 2 of this embodiment has the fixing device A of the first embodiment which is formed compactly and fits within the vertical frame 24, the assembly process can be simplified. As shown in FIG. 6, the movable partition panel 2 has a sound absorbing material 26 provided over the entire surface inside the panel body 21 in order to enhance the soundproofing effect. For example, the device disclosed in Patent Document 1 uses a first slide member with an inclined guide hole 11c, and also requires a second slide member as a mechanism for locking the sliding of the first slide member and an auxiliary pressing member arranged in series with the second slide member. This tends to increase the dimension in the left-right direction (the sliding direction of the first slide member) when viewed from the front. Therefore, it is difficult to fit this within the dimensions of the vertical frame members, and as a result, the fixing device protrudes inward beyond the vertical frame members. This requires forming a recess in the sound-absorbing material to avoid the protruding portion of the fixing device (i.e., increasing the number of processing steps). On the other hand, according to the movable partition panel 2 of this embodiment, as can be seen from Figures 6 and 9(a), "the dimension of the main body of the fixing device in the direction along the protruding direction of the horizontal sliding portion is smaller than or approximately the same as the dimension of the vertical frame member in the direction along the protruding direction of the horizontal sliding portion," in other words, "the fixing device is provided inside the panel body so as to be in contact with the end face, which is the side face at both ends of the panel body in the moving direction, and the face of the fixing device located opposite the end face is located closer to the end face than the end of the vertical frame member opposite the end face, or in approximately the same position," so there is no need to form a recess in the sound-absorbing material (i.e., no additional processing is required), and the assembly process can be simplified.

[0045] In the embodiment, an example is given in which the rotating cam member has a rotation locking function using a stopper, which is highly convenient as described above, but the present invention is not limited to this, and the rotation locking function may not be present. 12 shows a fixing device as an example of a fixing device without a rotation lock function. The same components as those of fixing device A of embodiment 1 are given the same reference numerals, and the description thereof will be omitted here. Although the box-shaped member 111', vertical slide portion 13', and rotating cam member 15' of the fixing device in Figure 12 differ in shape from the box-shaped member 111, vertical slide portion 13, and rotating cam member 15 of the fixing device A in embodiment 1, the basic concept is the same, so explanation here will be omitted. The spring S5 is a member that biases the horizontal slide portion 12' in the protruding direction. Since the biasing force of the spring S2 and the like is transmitted to the horizontal slide portion 12' via the rotating cam member 15', the spring S5 can be omitted in the same way as the spring S4. The fixing device in Figure 12 does not have a stopper, and therefore cannot achieve the function of a stopper as described above. However, in some cases, for example, if the weight of the movable partition panel is large or the friction between the pressure contact device and the floor surface is large, it may be possible to prevent the movable partition panel from moving even if the user releases their hand from the movable partition panel, even without a stopper. In addition, in Figure 12, there is no detachable structure for the pushing member or a rotation mechanism for the pushing member relative to the main body, but even in a fixing device that does not have the rotation lock function of Figure 12, either or both of the detachable structure for the pushing member and the rotation mechanism may be applied.

[0046] Furthermore, with regard to the vertical slide portion, an inclined surface (in Figure 1(b) the upper surface of the vertical slide portion 13 is inclined so that the left side is higher and the right side is lower) may be provided on the upper surface that comes into contact with the rotating cam member, thereby adjusting (optimizing) the pushing action (speed) of the pushing member. The downward movement of the vertical contact portion (protrusion) 152 of the rotating cam member 15 (i.e., the amount of pressing of the pusher member 14) is large at the beginning of rotation (FIGS. 1(b) and 3) and becomes smaller at the end of rotation (FIG. 2(b)). This is because the rotating cam member 15 performs circular motion, and the direction of movement (tangential direction) of the vertical contact portion (protrusion) 152 is nearly vertical at the beginning of rotation, whereas the direction of movement (tangential direction) of the vertical contact portion (protrusion) 152 becomes closer to horizontal at the end of rotation. This is preferable because it allows the pressing speed to be increased at the beginning of rotation when the pusher member 14 is not in contact with the floor surface, and the pressing speed to be decreased (instead, the pressing driving force to be increased) at the end of rotation when the pusher member 14 is in contact with the floor surface and applies further pressing force. However, it is undesirable that the pressing amount (speed) at the end of rotation becomes excessively low. Therefore, an inclined surface may be formed on the upper surface of the vertical slide portion 13 to convert the horizontal movement component of the vertical contact portion (convex portion) 152 into a vertical movement component of the vertical slide portion 13, thereby adjusting (optimizing) the pushing operation (speed) of the pushing member 14. The inclination angle of the inclined surface formed on the upper surface of the vertical sliding part may be determined as appropriate (taking into consideration the relationship with other configurations such as spring force) so that the pushing action (speed) of the pushing member in the function described above is appropriate, and as a result, it may be non-inclined, as in the fixing device described in embodiment 1. Furthermore, the inclined surface formed on the upper surface of the vertical sliding part is not limited to a single planar inclination, but may be a shape in which multiple planes are connected (where the inclination angle changes stepwise), or a curved surface (where the inclination angle changes continuously), etc. In addition, in this embodiment, the portion of the rotating cam member that comes into contact with the vertical slide portion is formed as a convex portion (vertical contact portion), but the present invention is not limited to this, and for example, the portion of the rotating cam member that comes into contact with the vertical slide portion may be formed into a horizontal or inclined flat shape, a curved shape, a spherical shape, etc. (an appropriate shape may be selected as appropriate in combination with the selection of the shape of the upper surface of the vertical slide portion).

[0047] In the embodiment, the motion converter that converts the horizontal pressure applied to the horizontal slide part into vertical motion is configured by a rotating cam member, thereby achieving a compact device. However, in terms of improving the ease of replacement of the fixing device described above (for which the main body is detachably attached to the end face of the partition panel) and the detachable structure and rotating mechanism of the pusher member for reducing the load between components, the motion converter of the present invention is not limited to a rotating cam member, and any mechanism that can "convert the horizontal pressure applied to the slide part into vertical motion" may be adopted. However, in the fixing device shown in Patent Document 1, a rod member 31 protruding upward is essential due to the structure of the mechanism for driving the pressure contact device, whereas the use of the rotating cam member described in the embodiment makes it possible to reduce the structure protruding outside the housing. This reduces the problem of the structure protruding outside the housing interfering with other components of the partition panel, making it difficult to remove the main body part from the partition panel, and improves the ease of removing the main body part from the edge side of the partition panel.The adoption of a rotating cam member therefore further improves the ease of replacing the fixing device described above, making it more preferable.

[0048] In the embodiment, the rotation mechanism that enables rotation of the pushing member 14 relative to the main body 1 is configured at the joint between the connecting member (shaft) and the pushing member, but the present invention is not limited to this. For example, the rotation mechanism may be configured at the joint between the connecting member and the vertical slide part, or the rotating mechanism may be configured in the connecting member itself by providing the connecting member with a joint mechanism (which may have multiple joints), or a combination of these may be used. In addition, in the embodiment, the rotation mechanism is exemplified as being composed of a rotation shaft member (pin member) and a receiving portion (groove) that rotatably receives it, but the present invention is not limited to this, and the rotation mechanism may use any mechanism that allows the pushing member to rotate relative to the main body portion, such as using a ball joint. In addition, it may be possible to allow not only rotational movement around a fixed axis or point but also swinging about an axis or central point. Figure 13 shows an example of a rotation mechanism that allows swinging of the rotation axis, with Figure 13(a) being a left side view (showing only the pushing member 14''') and Figure 13(b) being a front view (showing the state in which the shaft 18 and the pushing member 14''' have been removed). The pushing member 14''' shown in Figure 13 has a guide groove 1411''' that receives the shaft 18 and its engaging portion 181, which is formed wide so that the shaft 18 and its engaging portion 181 can be loosely fitted in the width direction of the movable partition panel (the left-right direction when viewed from the front (Figure 13(b)) to be movable (swingable). As a result, in addition to the rotational movement around the engagement portion 181 (pin member), the engagement portion 181, which serves as the axis of this rotational movement, can move in the width direction of the movable partition panel, and can more flexibly follow changes in the relative posture of the pushing member to the main body portion caused by the tilting of the aforementioned pressure welding device 22, thereby more effectively reducing the load generated between the parts.

[0049] In the embodiment, the receiving portion (groove) that rotatably receives the pivot shaft member is inverted L-shaped when viewed from the front, so that when the connecting member (shaft) is attached to the push-in member, it moves horizontally and then downward, but the present invention is not limited to this. The receiving portion (groove) that rotatably receives the pivot shaft member may be any that can rotatably and detachably receive the pivot shaft member (detachable from the fore-edge side), and may, for example, simply receive the pivot shaft member horizontally. In addition, the opening that serves as the entrance to the receiving portion (groove) that rotatably receives the pivot shaft member may be made larger than the receiving portion (groove) and tapered, thereby improving workability when attaching the connecting member to the pushing member.

[0050] In the embodiment, an example is given of a device that has both a detachable structure for the pushing member and a rotation mechanism for the pushing member relative to the main body, but the present invention is not limited to this and may have only one of the detachable structure or the rotation mechanism.

[0051] In the embodiment, the stopper 16 rotates to a vertical position (restricted position) due to its own weight, but the present invention is not limited to this. For example, a biasing means such as a spring that biases the stopper to rotate to the restricted position may be provided. Furthermore, a protrusion that engages with the stopper when the lateral slide stopper portion is pushed in and operates to rotate the stopper to the restricted position may be provided (for example, a protrusion similar to the engaging protrusion 1711 of the lateral slide stopper portion 171 that engages with the upper convex portion 161 when the lateral slide stopper portion 171 is pushed in and rotates the stopper 16 to the restricted position).

[0052] In the embodiment, the lateral slide portion and the lateral slide stopper portion protrude from the side surface, but the present invention is not limited to this. For example, the lateral slide portion and / or the lateral slide stopper portion may be provided so as not to protrude from the side surface (for example, provided flush with the side surface so that they can be pushed inward from there), and a protrusion or the like may be provided on the contacting side (the adjacent movable partition panel 2) to push the lateral slide portion and the lateral slide stopper portion inward.

[0053] In the embodiment, an example is given in which the shaft 18 is connected to the vertical slide portion 13 (the shaft 18 and the vertical slide portion 13 are separate), but the present invention is not limited to this, and the shaft (connecting member) may be configured integrally with the vertical slide portion.
