Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable wall that is suspended from the ceiling and moved and placed in order to freely partition a room, and in particular, the necessary amount of the movable wall hanger rail installed on the ceiling and the movable wall itself. The present invention relates to an extremely rational multi-degree-of-freedom moving wall that can significantly reduce the

Conventional movable walls have various limitations in their mobility due to their unique structure, in that they are transported by being suspended from hanger rails installed on the ceiling, and therefore, they have been used to increase the flexibility of room partitioning. This required many hanger rails and many types of special hanging wheels.

For example, in the layout diagram of the hanger rail shown in Figure 1, the hanger rail days, days,... are arranged orthogonally,
Hanging cars K, K, which only run straight, are run on hanger rails, and movable walls W, W,... are stored in one corner of the room.
Hang it and move it in the direction of arrow
This figure shows how the room is partitioned by the arrangement shown in Figure 2.

However, in this case, the movable wall only moves straight in a direction perpendicular to the wall surface and cannot change direction, so in order to place the movable wall at any position, a large number of hanger rails are required as shown in the figure. At the same time, a movable wall exclusively used in the vertical direction and a movable wall exclusively used in the horizontal direction is required, which increases the number of movable walls that are not always used, which is uneconomical. In addition, in the case of the layout shown in Fig. 2, there are branches S, S2, etc. on the hanger rail, and there are some suspension cars that hang movable walls W3, etc. that can only go straight at the branches S, etc. , one that curves at the branching point S and goes on the branching rail Hs, and one that curves at the branching point S but goes straight at the subsequent branching section S2. By doing so, the movable wall suspended by these hanging wheels can be guided to a free position. However, in this case as well, a single hanging wheel cannot move freely in any direction at a branch or orthogonal part of the hanger rail, so there is a limit to the spatial area in which a movable wall suspended from such a hanging wheel can move. Yes, if you try to place a movable wall in any location and facing any direction, you will inevitably have to prepare a large number of multiple types of movable walls, and you will also need a long hanger rail. Therefore, it is uneconomical. Furthermore, with such a movable wall, the range of movement of the movable wall is limited as described above, so the degree of freedom of partitioning is also significantly restricted. In addition, in order to eliminate the above-mentioned drawbacks, it is desirable that the hanging wheel be a so-called non-directional hanging wheel that can run in any direction, front, back, left, or right at the orthogonal or branching portions of the hanger rail.

Already known examples of such hanging wheels include:
A regular octagonal prism-shaped running body is provided with an annular groove that opens on the lower surface outside of the bolt insertion vertical hole provided in the center, and a plurality of rotations are radially arranged at equal intervals in the annular groove, At least the lower periphery of each rotor is mounted on a shaft so as to protrude from the lower opening □ of the annular groove, and the rotor is mounted radially at equal intervals on the upper side of each corner of the traveling body so as to be horizontally rotatable. In addition, at least the outer periphery of the wheels is urged to protrude from the upper surface of the traveling body, and a bolt with a thread carved into the lower side for suspending the sliding door is inserted into the bolt hole. There is a hanging wheel device for a sliding door that is inserted into the hanger rail so that it can rotate freely (see Tokusei No. 55-108579). The direction and the running direction of the hanging wheel are 45 degrees apart, so when you push the hanging wheel to start it, the hanging wheel rotates in the direction mentioned above, causing the hanging wheel to move in an unexpected direction and become unable to run. There was a problem. In addition, in order to increase the degree of freedom of the movable wall, it is necessary to make the movable wall relatively movable in the direction perpendicular to the hanger rail. A hanging door described in Japanese Patent No. 21247 is known.

However, in the case of this conventional door, one of the two hanging rods that hang the door is movable relative to the door, but the other is fixed to the door, so the door is connected to the hanger rail. Although it had the freedom to tilt, it did not have the freedom to actively move the door in a direction perpendicular to the hanger rail. The purpose of the present invention is to solve the above-mentioned disadvantages of conventional movable walls, such as limitations on the degree of freedom of partitions, uneconomical issues such as the length of hanger rails and the number of movable walls. In a movable wall for freely partitioning a room, the hanging wheels are suspended from hanging tools attached to two hanging wheels that run along a hanger rail laid in a shape, and are placed orthogonally to each other. a hanging wheel main body consisting of an upper main body and a lower main body each having four side walls, and a total of four upper vertical wheels each mounted eccentrically from the center line of the hanging odor rut on both sides of a pair of parallel upper side walls; A total of 4 pieces were installed on both sides of a pair of lower side walls perpendicular to the above upper side wall, eccentrically from the axial center line of the hanging fixture.
On the top surface of each of the upper and lower hanger rails on which these vertical wheels roll, there is a cutout groove in which the vertical wheels perpendicular to the running direction of the hanging wheel face each other through a gap. In addition, each of the two hanging tools has an idler wheel at its upper end that can move freely along the rail at the top of the moving wall, and each of the hanging tools can move through the idler wheel. The purpose of the present invention is to provide a multi-degree-of-freedom movable wall whose main feature is that the movable wall is movably suspended.

Next, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings starting from FIG.

Here, FIG. 3 is a front view of a step-type hanging wheel, which is an example of a non-directional hanging wheel that can be used for a movable wall, which is an embodiment of the present invention, and FIGS. 4 and 5 are a top view of the same hanging wheel. Figure, left side view, and Figure 6 are perspective views showing the behavior of the two-stage hanging wheel at the orthogonal part of the hanger rail. In these figures, the suspension body 1 has a structure in which an upper body 3 and a lower body 4 are integrally connected by a narrow central body 2. A hanging shaft 5, which is a kind of hanging shaft, which connects the hanging wheel main body 1 and its downward moving wall (not shown) is fixed to the hanging wheel main body 1, or can be rotatable. Two vertical wheels 7, 7, 7', 7' that can run on the same plane are rotatably attached to the left and right side walls 6, 6' of the upper body 3, and each vertical wheel is suspended. Distance e with respect to the center line 8 passing through the axis 5
, is eccentric. Also, the front and rear side walls 9, 9' of the lower body 4
is perpendicular to the left and right side walls 6, 6', and each of the front and rear side walls 9
, 9' each have two rotatable vertical wheels 10, 10 and 10', 10', each of which can run on the same plane. Therefore, the running direction of the vertical wheels 7, 7, 7', 7' and the running direction of the vertical wheels 10, 10, 10', 10' are perpendicular to each other. Also, vertical wheels 10, 10, attached to the lower body 4,
and 10', 10' are also eccentric by a distance e2 with respect to a center line 8' perpendicular to the center line 8 of the hanging shaft. One or more horizontal guides 12 are attached to the upper surface 11 of the hanging wheel body 1 as required. This guide rail 12 interferes with a vertical guide rail 14 provided as needed at the upper center of the hanger rail 13 to regulate the traveling direction of the hanging vehicle and to stabilize the traveling state. Next, the hanger rail on which the above hanging wheel runs will be explained.

The hanger rail 13 includes left and right side walls 16, 16' connected by an upper plate 15, left and right upper rails 17, 17' protruding inward from the left and right side walls 16, 16', left and right lower rails 18, 18, and a ceiling. H-beam 1 installed on the back
9, a mounting plate 21 for mounting the hanger rail 13 with a mounting piece 20 having a U-shaped cross section and a wedge plate 20'.
It is constructed by integrally having. The above upper rail 17,
17 constitutes the running surface of the upper vertical wheels 7, 7' of the hanging wheel;
Cut 2 in the upper left rail 17, 17 due to the running of the hanging wheel
2 through which the central body 2 of the hanging wheel passes.

The lower rails 18, 18 are the lower vertical wheels 10, 1 of the hanging wheel.
The cut 23 between the left and right lower rails 18, 18 is a portion through which the hanging shaft 5 passes. The distance 1 between the upper surface 24 of the upper rail 17 and the upper surface of the lower rail 18 is equal to the distance between the lower surface 25 of the upper vertical wheel 7 and the lower surface of the lower vertical wheel 16. The upper rails 17, 17 and the lower rails 18, 18 each have an arcuate cutout 26 with a depth d of about lm/m on the top surface of their respective tips.
26 and 27,27. Therefore, when the upper vertical wheels 7, 7' are in rolling contact with the upper rails 17, 17 as shown in the first figure and the hanging wheel is running in a direction perpendicular to the plane of the drawing, the lower vertical wheels 10, 10' exists above the arc-shaped notches 27, 27, and there is a gap between them corresponding to the depth d of the notches, so that the lower vertical wheels 10, 10' and the lower rails 18, 18 This allows for smooth running without contact or interference. Next, the traveling operation and the switching operation of the traveling direction of this suspended vehicle will be explained.

The traveling in the direction of the arrow x shown in FIG. 4 is as described above, with the upper vertical wheels moving on the upper rail and the lower vertical wheels floating on the rail surface. On the other hand, when the hanging wheel runs in the direction of the arrow Y perpendicular to this, the hanger rail 1 in the direction of the arrow
The lower vertical wheels 10, 1 run on the lower rail 18 of the hanger rail 13' in the direction of arrow Y, which is laid orthogonally to
It travels by rolling 0'. In this case, the upper vertical wheels 7, 7' are floating from the upper rail 17 with a gap d of about lm/m due to the notch 26,
It does not pose a hindrance to driving. FIG. 3 shows such a situation. FIG. 6 shows a state in which the two-stage hanging wheel approaches the perpendicular portions of the hanger rails 13, 13'.

Here, the solid line indicates the lower rail, and the two-dot chain line indicates the upper rail. For example, consider a case where a hanging wheel is traveling in the direction of arrow A and approaches orthogonal section B of the hanger rail. As shown in the figure, when the hanging wheel is in front of the orthogonal part, the lower vertical wheels 10, 10, 10', 10' are rolling on the lower rail 18, and the upper vertical wheels 7, 7 are rolling on the lower rail 18.
, 7', 7' are floating from the upper rail 17. When the hanging wheel reaches the center of the orthogonal part B shown in the figure, the lower vertical wheel 1
0, 10, 10', and 10' fit into the notch 27 of the lower rail 18 all at once, and each hanging wheel body descends by about lm/m. When the entire hanging wheel descends by about lm/m, the upper vertical wheels 7, 7, 7', 7, which had been floating until then,
' also comes into contact with the arcuate notch 26 of the upper rail 17.

In this way, the hanging wheel falls into the notches on all four sides at the center of the orthogonal part B, so it comes to a complete stop and enters a stable state in which it will not move in any direction unless a slightly larger force is applied.At the same time, all vertical wheels Since it comes into contact with the hanger rail, it is possible to advance in any direction, front and back, left and right, by pushing the moving wall with a slightly larger force. The fact that the hanging wheel automatically stops at the center of the orthogonal section means that the hanging wheel can always run in the center of any hanger rail, regardless of whether the hanging wheel subsequently moves forward, backward, left or right. This is an extremely important function for mobile wall hanging wheels. Next, a device for attaching a hanging tool to a movable wall used in the present invention will be explained with reference to the attached drawings from FIG. 7 onwards.

Here, FIG. 7 is a perspective view of both floating suspension vehicles, which is an example of the above-mentioned mounting device. The upper rail, upper vertical wheels, etc. in Figure 7 are omitted from illustration. In these figures, 31, 31 are lower rails of the hanger rail, on which hanging wheels 33, 33 equipped with lower vertical wheels 32 run. Each of the hanging wheels 33, 33 has an idler wheel 35, 35 connected to the lower part thereof through a hanging shaft 34, which is a type of hanging tool.
are connected. Therefore, each of the lower rails 31, 31 has a central opening 36, 36 through which the hanging shaft 34, 34 passes. The idlers 35, 35 are each attached to the lower part of a rail 37 attached to the upper part of the movable wall 4, and the wheels 38 provided on the sides of the wheels 38 displace the lower surface 39 of the rail 37, so that the idlers 35, 35 runs along the lower surface 39 of the rail. On the lower surface 39 of the rail, a hanging shaft 34,
Guide holes 40, 40 through which 34 passes are bored,
Horizontal direction control wheel 41 provided on the top surface of each hanging wheel 33, 33
This direction control hole 40 or 401 is equipped with iron. That is, the direction control wheel 41 prevents inclination between the moving wall and the hanging shaft by interfering with the guide hole 40.
Therefore, when the idler vehicle runs along the rail, the direction control wheel 41 comes into contact with the end 42 or 43 of the guide hole 40, so that the idler vehicle stops traveling. The directions are equal, and the distance Lo from one right end 42 or left end 43 to the other right end 42 or left end 43 is equal to the center-to-center distance of the lower rails 31, 31. Therefore, even in the suspended state shown in FIG. 7, since the movable wall 4 is suspended from the hanging wheels 33, 33 via the idler wheels 35, 35, if a force is applied to the movable wall 4 in the direction of the arrow 44, The moving wall moves freely in that direction, and the amount of protrusion L of the moving wall from the hanger rail is
4 can be changed, so even if the distance between the hanger rail and the wall of the room varies, it can be adjusted accordingly.

Further, even when there are notches 27L and 27R for lowering and temporarily stopping the suspension wheels 2Z and 2Z on the rail as shown in FIG. 8, both suspension shafts 34a can be moved freely by the idler wheels. Even if the movable wall approaches the orthogonal parts 30L and 30R of the hanger rail from the right side, both hanging cars will always be shifted to the right or left side, The interval between parallel hanger rails is always equal to the interval Lo between the orthogonal parts 30L and 30R, and the direction can be changed immediately upon reaching the orthogonal part.
This will be explained with reference to the figures. FIG. 9 is a plan view showing how the movable wall according to the present invention is being transported in an exhibition hall or the like. In order to arrange the movable walls in the exhibition hall with the layout shown in the figure, the movable walls Wa are moved from the movable wall storage 45 along the hanger rails Ha, Ha and carried out to the exhibition hall 46. If the movable wall is to be moved in that position, it is possible to move the movable wall in the direction of the arrow 47 as shown in Wb, but if the hanging wheel approaches the orthogonal parts 48, 49, etc. of the hanger rail, The moving wall is W
When the hanging wheel is brought to the positions c and Wd, the traveling direction of the hanging wheel can be changed by 90 degrees and it can be made to travel in the direction of the arrow 50 as shown by We and Wf. In addition, in order to change the direction at right angles to the moving wall Wg and run in the direction of arrow 50, use the hanger rail H.
It is necessary to change the direction as shown by the arrow 51 at the orthogonal portions 48, 49, etc. of a. To make this change of direction,
The hanging shaft fixed to the hanging wheel must be movable with respect to the moving wall, but since the hanging shaft and the moving wall are connected by the idler wheels 35, 35 as described above, the direction can be changed without any problem. It is. Also, even if the distance between the hanger rail and the side wall of the room -L3 is large as shown in the figure, if the hanging shaft and the movable wall are movably connected via the idler as described above, Even if the size of . Furthermore, the moving wall is W
It is possible to arrange the hanging shaft at an arbitrary angle with respect to the hanger rail as shown in h or Wi, and this is also an effect of connecting the hanging shaft to the movable wall via the idler. In this way, the movable wall according to the present invention can change direction in any direction at any orthogonal part, so it can be transported to any location. Multiple hanger rails Hb, H in the horizontal direction
If B, . In a movable wall for freely partitioning a room, the above-mentioned hanging wheels are suspended, transported, and placed via hanging tools attached to two hanging wheels that run along a hanger rail installed perpendicular to the ceiling. The main body of the hanging wheel consists of an upper body and a lower body each having four orthogonal side walls, and a total of four upper perpendicular hanging tools are attached to both sides of a pair of parallel upper side walls eccentrically from the center line of the bag. The wheels and a pair of lower side walls perpendicular to the upper side wall are mounted eccentrically from the shaft center line of the hanging tool, totaling 4.
On the top surface of each of the upper and lower hanger rails on which these vertical wheels roll, there is a cutout groove in which the vertical wheels perpendicular to the running direction of the hanging wheel face each other through a gap. In addition, each of the two hanging tools has an idler wheel at its upper end that can run freely along the rail at the top of the moving wall, and each of the hanging tools moves via this idler wheel. Since it is a multi-degree-of-freedom movable wall characterized by hanging the wall movably, it is necessary to use hanger rails in either the vertical direction or the horizontal direction, as shown in the example of the layout diagram shown in Fig. 9. The number of hanger rails can be significantly reduced, for example to only two, and there is no need to lay the hanger rails vertically and horizontally in the shape of the base as in the past, so the number of hanger rails can be reduced and the installation work can be omitted. Furthermore, instead of preparing a large number of moving walls with limited running trajectories using a large number of special hanging wheels as in the past, it is possible to select a moving wall in any position using one type of hanging wheel. This has succeeded in dramatically reducing the number of partitions and doubling the degree of freedom in partitioning.

In addition, in the present invention, two vertical wheels are provided on each side wall of the rectangular hanging wheel main body as an optimal example of a so-called omnidirectional hanging wheel that can move forward, backward, left, and right at the orthogonal part of the hanger rail. A notch is provided on the top surface of the hanger rail to prevent the vertical wheels perpendicular to the running direction from interfering with the hanger rail, so the hanger rotates at the right angle of the hanger rail and travels like a conventional omnidirectional hanging wheel. There is no drawback such as the inability to control the direction, the traveling direction is controlled extremely accurately, and the two hanging tools that hang the moving wall are both movable relative to the moving wall, so it is different from the conventional hanging wheel. Compared to a case where one hanging shell is fixed to a movable wall, the degree of freedom of movement relative to the hanger rail is further improved, so the degree of freedom of the movable wall is dramatically improved compared to conventional devices. It will improve.
