Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition panel that divides an indoor space into an appropriate size by pulling out or folding and storing a large number of connected panels.

0002

2. Description of the Related Art An example of a partition panel composed of a large number of foldably connected panels will be described with reference to FIGS. 14 and 15. In the partition panel shown in FIG. It is rotatably connected to the side edges of adjacent panels 1 over the entire length in the vertical direction by synthetic resin or aluminum long hinges 2, and each panel 1 is movable relative to the hanger rail 4 by a runner 3 at one end of its upper edge. The guide shaft 5 provided at one end of the lower edge is supported in a guide groove 6 provided in the floor surface. And Figure 14
As shown in the figure, when each panel 1 is pulled out between the wall surfaces 7 along the hanger rail 4, one end of the upper and lower edges of each panel is supported by the hanger rail 4 and the guide groove 6, making it possible to partition the indoor space. As shown in Fig. 15, when each panel 1 is folded up by pushing the front end side of the connected panels toward the wall surface 7 on the rear end side of the panel along the hanger rail 4, the partitioned indoor space is opened. be done.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned partition panels, each panel is only connected by long hinges 2, so when each panel 1 is pulled out along the hanger rail 4, each panel 1 is difficult to form in a completely straight line, and when each panel 1 is folded, it is difficult to rotate each panel 1 at right angles to the hanger rail 4 so that they are completely overlapped. Undesirable.

Furthermore, since the runner 3 is provided at one end of the upper edge of the panel 1, when each panel 1 is folded as shown in FIG. 15, the center of gravity of each panel is not located below the hanger rail 4. Therefore, unless the lower end of the panel 1 is supported by the guide shaft 5 in the guide groove 6, each panel 1
is suspended and supported from the hanger rail 4 in an inclined state. Therefore, the guide shaft 5 and a guide groove 6 for supporting the guide shaft 5 are required, and in order to install such a partition panel, it is necessary to process the floor surface and provide the guide groove 6. The time work becomes complicated.

[0005] Therefore, if each panel is suspended and supported by a runner at the longitudinal center of its upper edge, the center of gravity of each panel will be located below the hanger rail whether the panel is pulled out or folded. The guide shaft 5 and the guide groove 6 can be omitted, and the hinge is equipped with a biasing force that biases each panel into a state in which the panels are connected in a straight line or in a state in which they are rotated at right angles to the hanger rail and folded. The above problem can be solved by connecting each panel, but even if you try to fold each panel by pushing the panel at the front end, the biasing force of the hinge makes it difficult to fold the panels sequentially from the rear end side. Convolution operation becomes complicated.

[0006]An object of the present invention is to make it possible to reliably pull out each panel in a straight line along a hanger rail when pulling out a panel, and to ensure that each panel can be folded in a direction perpendicular to the hanger rail when folded. A partition panel that improves the aesthetic appearance, simplifies installation work by eliminating the need for floor processing during design, and allows panels to be easily folded by pushing the front end panel in the panel folding direction along the hanger rail. is to provide.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention rotatably connects a plurality of intermediate panels with a long hinge attached to the entire length of the side edge in the width direction of the intermediate panel. Each panel can be connected in a range from a straight line state to a state in which they are folded one by one in parallel, and one rear end panel with a width half of the intermediate panel is attached to the rear end of the plurality of connected intermediate panels. Connected with a long hinge in the same way as the middle panel,
The rear end of the upper edge of the rear end panel and the longitudinal center of the upper edges of the plurality of intermediate panels are suspended and supported so as to be rotatable in the horizontal direction by a runner movably supported by a hanger rail, and each of the panels is A biasing force is provided between two adjacent panels to cause the panels to rotate either in a linearly connected state or in a parallel folded state depending on the rotation angle between both panels. A hinge is attached to the rear end panel, and when the rear end panel is moved to a panel storing position at one end of the hanger rail, the rear end panel is rotated in a direction perpendicular to the hanger rail to fold each panel. The configuration includes a starting device that starts the operation.

[0008]

[Operation] With the above means, each panel is stably maintained by the biasing hinge either in a straight line along the hanger rail or in a folded state by folding each panel parallel to each other. When folding up panels that have been pulled out, apply operating force to the front panel to move each panel toward the storage position, and the activation device will rotate the rear panel in a direction perpendicular to the hanger rail. , based on the rotation of the rear end panel, the panels connected to the rear end panel are sequentially rotated and folded.

[0009]

[Example] An example embodying this invention is shown below in Figure 1.
~Explained according to FIG. 13. Note that parts corresponding to those in the conventional example will be described with the same numbers. As shown in FIG. 1, the partition panel consists of an odd number of intermediate panels 1 of the same width whose widthwise side edges are connected by long hinges 2.
At the rear end, there is a rear end panel 1a that is half the width of the middle panel 1.
are similarly connected by a long hinge 2, and at the front end of the intermediate panel 1 there is a front end panel 1b having approximately the same width as the rear end panel 1a, and an operation panel 1c narrower than the front end panel 1b. connected. The center part of the upper edge of the operation panel 1c in the width direction is suspended and supported by a hanger rail 4 via a runner 3, the front end panel 1b is not provided with a runner 3, and the three intermediate panels 1 are provided with a center part in the width direction. Only the middle panel 1 is suspended and supported from the hanger rail 4 by a runner 3 at the center of its upper edge in the width direction, and the rear end panel 1a is suspended and supported from the hanger rail 4 via the runner 3 at the rear end of its upper edge. There is. Therefore, every other intermediate panel 1 and rear end panel 1a are suspended and supported from the operation panel 1c by the runners 3, and these panels 1 and 1a can be rotated horizontally with respect to the hanger rail 4 by each runner 3. Supported. Note that only the operation panel 1c is provided with a guide shaft (not shown) protruding into the hanger rail 4 at the rear end of its upper edge, and is movable and rotatable along the hanger rail 4 by the guide shaft and the runner 3. It is supported irrevocably. A handle 11 is provided at the center in the vertical direction of the operation panel 1c, and each panel 1 can be pulled out and folded using the handle 11.

At the upper end of each long hinge 2, the front and rear panels connected by the long hinge 2 are maintained in a straight line along the hanger rail 4, or rotated at right angles to the hanger rail 4. Biasing hinge 1 with a biasing force to maintain
2 is attached. The structure of the biasing hinge 12 is shown in FIGS.
Explaining according to FIG. 8, as shown in FIG. 6, the base ends of a pair of attachment arms 14a and 14b are rotatably supported on the pedestal 13 at different pivot points X1 and X2, respectively. coincides with the rotation fulcrum of the long hinge 2, and the tapping screw 15 is screwed into the through hole provided at the rotation fulcrum of the base 13 and the through hole provided at the rotation fulcrum of the long hinge 2. The hinge 2 and the base 13 are fixed. Further, the mounting arms 14a, 14b are fixed to the upper edges of the panels 1, 1a, 1b, 1c connected by the long hinge 2.

Each of the mounting arms 14a, 14b is formed into a substantially cylindrical shape, and a pivot 16a, 16b is fitted into the mounting arm 14a, 14b so as to be retractable. A movable folding surface 17 is formed and the mounting arms 14a, 1
A coil spring 19 is disposed between the base ends of the pivots 16a, 16b in the mounting arms 14a, 14b and spring receivers 18 provided in the mounting arms 14a, 14b. The folding surfaces 17 of the pivots 16a and 16b are pressed against the cam surface 20 of the base 13 by the urging force of the coil spring 19 with the spring receiver 18 as a fulcrum.

The cam surface 20 rotates from a state in which the mounting arms 14a, 14b are positioned in a straight line as shown in FIG. 6 to a state in which the mounting arms 14a, 14b are located in parallel as shown in FIG. A cam ridge 20a exists in the intermediate position, and the folding surface 17
When getting over 0a, install the mounting arms 14a and 14b.
Since the distance between the rotation centers X1, X2 and the folding surface 17 is expanded, the pivots 16a, 16b are
It is pushed into the mounting arms 14a, 14b against the urging force of 9.

Further, the folding surface 17 and the cam surface 20 are formed when the mounting arms 14a and 14b are positioned in a straight line as shown in FIG.
4a and 14b are configured to be stably held in a parallel position. That is, when the mounting arms 14a and 14b are positioned in a straight line, the biasing force of the coil spring 19 is applied to the cam surface 20 and the folding surface 17.
The attachment arms 14a, 14b are configured so that the center of action F that acts on the rotary arm 14a, 14b is located on the cam crest 20a side from the center line L of the rotating arms 14a, 14b,
Furthermore, even when the mounting arms 14a and 14b are positioned in parallel as shown in FIG. It is meant to be retained.

A rotation regulating piece 21 is formed at one end of the folding surface 17 and projects in a direction along the center line L of the mounting arms 14a, 14b. A protrusion 22 is formed to prevent rotation of the mounting arms 14a, 14b in a direction opposite to the rotational direction. Further, a locking pin 23 that protrudes upward is attached between the protrusions 22 of the pedestal 13, and the locking pin 23 is arranged so that the mounting arms 14a, 14b are linear and each panel is linearly aligned along the hanger rail 4. When the hanger rail 4 is pulled out as shown in Figures 4 and 5,
It is provided at a position abutting the lower opening groove side surface 4a.

The biasing hinge 12 as described above is attached to the upper end of the long hinge 2 between each panel, and the direction of attachment thereof coincides with the rotating direction of the long hinge 2, and the biasing hinge 12 is attached to the upper end of the long hinge 2 between each panel. Biasing hinges 12 are attached to each other so as to rotate in opposite directions. The rear end panel 1a can be arranged in two different ways, from when each panel 1, 1a, 1b, 1c is pulled out in a straight line between the wall surfaces as shown in FIG. 2, to when each panel 1, 1a, 1b, 1c is folded as shown in FIG. The rear end moves in the direction along the hanger rail 4. That is, as shown in FIG. 13, a hinge rod 24 is attached to the lower rear end of the rear end panel 1a, and the tip of the hinge rod 24 is supported by a hinge receiver 25 attached to the lower end of an adjustment frame 29, which will be described later. There is. The hinge receiver 25 has a long hole 26 formed in the direction along the hanger rail 4, and the tip of the hinge rod 24 is inserted into the long hole 26, so that the hinge rod 24 can move within the range of the long hole 26. Rotatably supported. Therefore, the rear end panel 1a is movable along the hanger rail 4 with a stroke defined by the elongated hole 26. The hinge rod 24 is a coil spring 28 whose fulcrum is a mounting bracket 27 provided at the lower end of the rear end panel 1a.
The flange 24a provided near the tip of the hinge rod 24 is always urged downward by the urging force of the hinge receiver 2.
5, and its tip portion protrudes further into the elongated hole 26 than the flange 24a.

At the top of the hinge receiver 25, there is an adjustment frame 2 for closing the gap between the wall surface 7 and the rear end panel 1a.
9 is attached to the wall surface 7. The adjustment frame 29 is shown in Figure 12.
As shown in FIG.
It is comprised of a rotating piece 31 that is rotatably supported by the user and a torsion coil spring 32 for rotating the rotating piece 31 back to its original position. One piece of the fixed piece 30 is fixed to the wall surface 7, and a shaft portion 33 is formed at the edge of the one piece. A fitting portion 34 formed at one end of the rotating piece 31 is rotatably fitted to the shaft portion 33, and one end of the torsion coil spring 32 is fixed to the fixed piece 31. The other end is fixed to the rotating piece 31, and as shown in FIG. 12, the rotating piece 31 and the fixed piece 30 are always at right angles due to the urging force of a torsion coil spring 32 with the fixed piece 30 as a fulcrum. is maintained. Therefore, the adjusting frame 29 is always maintained in a groove shape, and the rotating piece 31 can also be rotated in the direction of arrow B shown in FIG. 12 against the biasing force of the torsion coil spring 32.

When each panel is pulled out in a straight line between the wall surfaces 7 as shown in FIG. to prevent a gap from forming between the wall surface 7 and the rear end panel 1a,
As shown in FIG. 3, when each panel is folded, the rear end panel 1a rotates while moving into the adjustment frame 29 along the long hole 26 of the hinge receiver 25, so the rear end panel 1a
When pressed, the rotating piece 31 is rotated outward.

As shown in FIG. 9, the base end of a kicking arm 36 is fixed to a hanging shaft 35 of the runner 3 that supports the rear end panel 1a. The kicking arm 36 projects horizontally from the hanging shaft 35, and a case 37 covering the kicking arm 36 is fixed to the hanger rail 4. When each panel is pulled out linearly between the wall surfaces 7 as shown in FIG. 2, the kicking arm 36 protrudes diagonally rearward and is separated from the inner surface of the case 37, as shown in FIG. Adjust the rear end panel 1a from the stile 2
9, the kicking arm 36 comes into contact with the inner surface of the case 37, as shown by the chain line in FIG. 10, and the rear end panel 1a begins to rotate about the hanging shaft 35.

In this way, the rear end panel 1a is rotated, and the folding surfaces 17 of the pivots 16a, 16b of the biasing hinge 12 connected between the rear end panel 1a and the intermediate panel 1 connected thereto are rotated. After getting over the cam ridge 20a, the rear end panel 1a and the intermediate panel 1 connected to the rear end panel 1a are automatically folded into a parallel state as shown in FIG. When the panel 1 is rotated, the subsequently connected intermediate panel 1 is automatically rotated and folded. Therefore, the kicking arm 36 acts as a starting device for starting the rotational movement of each panel.

Next, the operation of the partition panel constructed as described above will be explained. Now, when each panel is pulled out between the wall surfaces 7 as shown in FIG. 29 is located on the opening side. In addition, in this state, the biasing hinge 1 at the upper end of each long hinge 2
As shown in FIG. 5, the locking pins 23 provided on the hanger rails 2 abut against the lower side surface 4a of the hanger rail 4 to prevent each biasing hinge 12 from rotating in a direction opposite to the normal rotation direction. .

From this state, when holding the handle 11 and applying an operating force to the operation panel 1c in the direction of the arrow C in FIG. Move in the direction of arrow C. Then, the tip of the kicking arm 36 provided on the rear end panel 1a comes into contact with the inner surface of the case 37, and the rear end panel 1a is rotated as shown in FIG. The biasing hinge 12 between the panel 1 is rotated,
As the intermediate panel 1 rotates, the biasing hinge 12 that connects the subsequent intermediate panel 1 begins to rotate. and,
Furthermore, when each panel is moved in the same direction via the operation panel 1c, the biasing hinge 1 located at a position close to the rear end panel 1a
Starting from 2, the folding surfaces 17 of the pivots 16a and 16b pass over the cam ridges 20a of the cam surface 20, and each panel is rotated until it is perpendicular to the hanger rail 4, and then the operation is performed as shown in FIG. Each panel 1, 1a, 1b except panel 1c is folded so as to be perpendicular to the hanger rail 4.

At this time, the rear end panel 1a has its hinge rod 24 inserted into the elongated hole 2 of the hinge receiver 25, as shown by the chain line in FIG.
Since the adjusting frame 29 of 6 is located at the back side and is rotated in a direction perpendicular to the hanger rail 4 at this position, the rotating piece 31 is located on the side of the rear end panel 1a as shown in FIG. It is pressed and rotated outward. On the other hand, when pulling out each folded panel, operate panel 1 from the state shown in Figure 3.
If c is moved in the direction of arrow D along the hanger rail 4, the front end panel 1b connected to the operation panel 1c will be sequentially rotated and moved in the direction along the hanger rail 4, and eventually each panel will move as shown in FIG. It is drawn out linearly along the hanger rail 4. In this state, the locking pins 23 of each biasing hinge 12 come into contact with the lower side surface 4a of the hanger rail 4, as shown in FIG.

As described above, in this partition panel, each panel is suspended and supported from the hanger rail 4 by the runner 3 at the middle part of its upper edge in the width direction, so that each panel can be in a pulled out state or a folded state. In either state, the center of gravity of each panel is located below the hanger rail 4. Therefore, it is not necessary to provide a guide groove on the floor surface to support the lower end of the panel 4, and the installation work becomes easy.

Furthermore, since every other panel in the intermediate panel 1 is suspended and supported by the runners 3, the friction between the runners 3 and the hanger rail 4 is reduced, and folding and pulling operations can be performed with a slight operating force. It can be carried out. Each panel is connected by a long hinge 2 and a biasing hinge 12, so the biasing hinge 12 allows the panels to be bent so that the scissor angle between the panels connected by each long hinge 2 is less than a certain angle. For example, pivots 16a and 16b are attached to the same biasing hinge 12.
The folding surface 17 of the biasing hinge 1 passes over the cam ridge 20a.
The panels connected at each long hinge 2 are automatically rotated so that they are in a parallel state, that is, perpendicular to the hanger rail 4, and the scissor angle between the panels connected at each long hinge 2 is a certain angle or more. When stretched, the folding surfaces 17 pass over the cam ridges 20 in the opposite direction and each panel is automatically rotated until it is in a straight line along the hanger rail 4. Therefore, each panel can be folded in a direction perpendicular to the hanger rail 4 to reduce storage space, and each panel can be pulled out in a straight line along the hanger rail 4, resulting in an aesthetically pleasing design. Partition panels can be configured.

[0025] Also, a kick-out arm 3 is provided on the rear end panel 1a.
6 is provided, and the rear end panel 1 can be opened by operating the operation panel 1c.
If a is moved into the adjustment frame 29, the kicking arm 36
When the rear end panel 1a comes into contact with the inner surface of the case 37 and is rotated, the rear end panel 1a is rotated, and a trigger for rotation is given to the biasing hinge 12 that connects the rear end panel 1a and the intermediate panel 1 connected thereto. Based on that opportunity, the rear end panel 1a
Since the panels are sequentially rotated in the folding direction from the biasing hinge 12 located close to , each panel can be easily folded by simply moving the operation panel 1c along the hanger rail 4.

[0026]

Effects of the Invention As detailed above, the present invention makes it possible to reliably pull out each panel in a straight line along the hanger rail when pulling out the panels, and to ensure that each panel is pulled out in a direction perpendicular to the hanger rail when folded. It is foldable to improve the aesthetic appearance, simplifies the installation work by eliminating the need to process the floor surface during design, and allows the panel to be folded by pushing the front end panel along the hanger rail in the panel folding direction. To provide an excellent effect of providing a partition panel that can be easily manufactured.
