Description

[Detailed Description of the Invention] The present invention relates to orthogonal portions (intersections) of hanger rails that are running tracks for movable wall hanging wheels (hereinafter referred to as hanging wheels).
The present invention relates to a traveling control device for a suspended vehicle that has a high degree of freedom in controlling the traveling direction and allows the suspended vehicle to run smoothly.

Conventionally, this type of suspension wheel was manufactured by, for example, the Japanese Patent Application Publication No. 58
The one disclosed in Publication No. -185881 is known.

The suspension wheel disclosed in the above publication will be explained based on FIGS. 1a and 1b. The same figure shows the running state of the hanging wheel (the state where the hanging wheel approaches the part perpendicular to the hanger rail).

In the figure, reference numeral 1 is the suspension main body, which has a vertical ground motion wall suspension shaft 2 (a shaft for suspending the movable wall downward) below the center, and two vertical wheels 3a on each of the four sides, front, back, left, and right. , 3a, 3b, 3b, 3c, 3c, 3
d and 3d rotatably. Reference numeral 4 denotes a hanger rail installed on the ceiling, which intersects perpendicularly at the intersection shown in the figure.

However, these hanger rails are shown in Figure 1a.
It shows a state cut along the central horizontal plane, and shows the running plate 4a at the bottom, but the actual one is the first one.
As shown in Figure b, the lower running plates 4a, 4
a, a vertical side wall 4b following this, a horizontal upper wall 4c connecting the side walls at the upper end, and a guide rail 4 continuously provided in the longitudinal direction at the center of the lower surface of the upper wall 4c.
The vertical wheels 3a, 3b, 3c, and 3d contact the upper surface (running surface) of the running plate 4a, so that the hanging wheel main body 1
runs on a hanger rail with a moving wall suspended.

Reference numeral 5 denotes a groove formed on the upper surface of the running plate 4a, which is continuous in the rail axis direction and has an arc-shaped cross section, for example, as indicated by the arrow X.
This is to prevent the vertical wheels 3a to 3b located perpendicular to the running direction shown by and the upper surface of the running plate 4a from contacting and interfering with each other when the hanging wheel main body 1 is running.

Four guide rollers 6 are provided on the upper surface of the suspension wheel body 1.
a, 6b, 6c, and 6d are arranged at regular intervals, and as shown in the figure, they contact the left and right sides of the guide rail 4d through a minute gap, and the hanging wheel main body 1 is guided by the guide rail 4d. and maintain a straight line.

Then, when the hanging wheel main body 1 moves straight in the direction of the arrow X, for example, and approaches the orthogonal part shown in the first figure, the front wheel 3a of the wheels 3a and 3b perpendicular to the running direction moves to the cut E ( The suspension shaft 2 passes over the groove, and the load applied to the suspension shaft 2 causes the suspension wheel body 1 to tilt. If the hanging wheel continues to move forward, there will be a break E.
The wheel 3a that fell off collides with the running plate and gives an impact to the hanging vehicle and the moving wall. When the hanging wheel moves further forward and reaches the center of the orthogonal part of the hanger rail as shown in FIG. Fits in, thereby all vertical wheels 3a
3d to 3d fit into the arcuate grooves 5 in the longitudinal and lateral directions, and the movement of the hanging wheel is temporarily stopped.

Therefore, if a force is applied to the suspended wheel main body 1 in any direction in the front, back, left, or right direction at this central position, the suspended wheel main body 1 will begin to move in that direction, making it possible to change the running direction to any desired direction.

However, as mentioned above, such hanging wheels can freely change the direction of travel, making them extremely practical, and the suspension force is strong as they receive the load from a large number of vertical wheels. As a result, all the vertical wheels of the hanging wheel fit into the groove 5 at the center of the orthogonal part of the hanging wheel, and as a result, the hanging wheel tries to start anew from this stopped state (the state where the entire hanging wheel has sunk by the depth of the groove 5). In this case, the vertical wheels in the traveling direction must escape from the groove 5 and ride on the upper surface (running surface) of the running plate 4a. The depth of this groove 5 is determined by the vertical wheel 3 that is perpendicular to the traveling direction of the hanging wheel, which swings slightly from side to side while traveling straight.
a, 3b need to have a fairly deep radius so as not to interfere with the top surface of the running plate 4a, and since the vertical load acting on one hanging wheel usually ranges from several hundred kg to several tons, the vertical wheels are In order to overcome the groove 5 and escape, it becomes a very large resistance.

In addition, in the case of a movable wall, in order to move it, it is not possible to directly push the hanging wheel stored in the ceiling, but rather by pushing the movable wall hanging from the hanging wheel. If the resistance due to the groove 5 is large, it may become practically impossible to move the hanging wheel from the orthogonal part of the hanger rail.

Therefore, it is an object of the present invention to create a smooth running condition so that the hanging wheel can cross the cut in the hanger rail without receiving impact even at the center of the orthogonal part of the hanger rail, and can start with a small force. The gist of this is to install a plurality of vertical wheels on each of the four sides of the suspension wheel body, which has a substantially right-angled hexahedral shape, at a height that touches the same horizontal plane, and to install a plurality of vertical wheels on the axis of the suspension wheel body. A single auxiliary wheel is attached around the axis of the vertical axis, and includes a horizontal and annular ball receiving member and a plurality of balls that roll in contact with the lower surface of the ball receiving member in an annular manner. , 4 of the orthogonal part of the hanger rail having a running surface forming a running track of the vertical wheels.
A running auxiliary plate having the same height as the running surface is attached to the corner, and an arcuate groove in which a vertical wheel perpendicular to the running direction is loosely fitted is formed on the upper surface of the running auxiliary plate, and The present invention provides a traveling control device for a movable wall hanging wheel, in which flat support plates, which are in direct contact with the plurality of balls and form the traveling surface of the auxiliary wheels, are attached above the four corners.

Next, a second example embodying the present invention will be described.
This will be explained with reference to the accompanying drawings below.

The vertical auxiliary wheels 15a to 15d are mounted symmetrically in the front and rear, at a height that allows them to come into contact with the running surface 17 of the hanger rail 16, which is the same horizontal plane.

As shown in FIG. 5, a hanging shaft 18, which is an example of a vertical shaft, is fitted onto the vertical center axis of the hanging wheel main body 10. As shown in FIG. This hanging shaft 18 has a bolt part 19 carved at the lower end for hanging the movable wall, and the upper end of the hanging shaft 18 when the hanging wheel main body 10 approaches the orthogonal part of the hanger rail 16, which will be described later. , auxiliary wheels 20 for supporting the load acting on the suspension wheel body 10
is installed.

That is, a vertical female thread 21 is formed at the center of the upper end of the hanging shaft 18, and a bolt member 23 having a male thread 22 is screwed into this female thread 21. A sleeve 25 is fixed to the tip of the hanging shaft 18 by the head 24 . On the lower surface of the flange-shaped head 24,
The upper surface of an annular ball receiving member 26 centered on the axis position of the hanging shaft 18 comes into contact with the lower part of the ball receiving member 26.
A plurality of balls 27 are rotatably attached to the lower surface of the ball receiving member 26 by a retainer 28, and the balls 27 contact the lower surface of the retainer 26 in an annular manner.
By sandwiching the lower surface of the inner ring 8 between the flange-shaped head 24 and the protrusion 29 of the sleeve 25, the upper part of the hanging shaft 18 is held with the ball 27 in rolling contact with the lower surface of the ball receiving member 26. can be attached to. A thrust bearing-shaped auxiliary wheel 20 is constituted by the ball 27, the ball receiving member 26, and the like. As this auxiliary wheel 20, for example, a commercially available thrust bearing can be used.

Further, the hanging shaft 18 has horizontal wheels 30 rotatably provided at the lower part of the hanging wheel main body 10. This wheel 30 is connected to the hanger rail 16 as shown in FIG.
A groove 3 is a cut in the hanger rail for the hanging shaft 18 to pass between the left and right running surfaces 17, 17.
1 and comes into contact with the side walls 32, 32 of the groove 31, thereby preventing the hanging wheel main body 10 from tilting in the left-right direction.

Furthermore, horizontal guide wheels 33 are rotatably attached to each corner of the upper surface of the hanging wheel main body 10, and these guide wheels 33 contact the guide wall 34 of the hanger rail 16 by rolling. , the hanging wheel body 10 can travel straight along the hanger rail 16.

The above-mentioned hanger rail 16 has a top plate part 35 having a roughly C-shaped cross section as shown in FIG. 2 and is to be attached to a structural member in the attic, and a connecting part 36 connected diagonally downward from the left and right ends of the top plate part 35, as shown in FIG. Each connecting part 36, 3
6 connected to the vertical guide wall 34,3
4, and the running surface 1 forming the running track of the vertical wheels 12a to 12d and the vertical auxiliary wheels 15a to 15d.
Left and right running plates 37, 37 having 7 on the upper surface, and side walls 38, 3 for connecting the running plates 37 and the connecting portion 36 and accommodating the vertical wheels 12a to 12d.
8, and side walls 32, 32 of the groove 31, which is provided at each end of the running plates 37, 37 and forms a guide wall for the wheel 30.

Therefore, for example, in the state shown in FIG. 2, when the hanging wheel main body 10 runs straight along the hanger rail 16, the vertical wheels 12 parallel to the running direction
c, 12d and vertical auxiliary wheels 15c, 15d are in rolling contact with the running surfaces 17, 17 of the running plates 37, 37, and the load applied to the hanging wheel body 10 via the hanging shaft 18 is supported by these six wheels. The vertical wheels 12a, 12b and the vertical auxiliary wheels 15a, 15b, which are perpendicular to the running direction, are all located on the groove 31 and away from the running surface 17. Therefore, the vertical wheels and vertical auxiliary wheels that are perpendicular to the running direction do not interfere with the hanger rail 16, and the hanging wheel main body 10 can smoothly run in the direction perpendicular to the plane of the paper in FIG. 2. The wheels 30 contact the side walls 32 of the grooves 31 as described above to prevent the hanging wheel main body 10 from tilting in the direction parallel to the paper surface of FIG.
4 and guides the hanging wheel body 10 to run straight along the hanger rail.

Next, the structure of the orthogonal part of the hanger rail and the running state of the hanging wheel in this part will be explained with reference to the drawings from FIG. 7 onwards.

As shown in FIG. 8, the hanger rails 16 are orthogonally connected in a cross shape around a top plate 39 attached to a structure in the attic. Bolt hole 40
is for inserting bolts for attaching the hanger rail into the top plate 39. Moreover, on the top plate 39,
Auxiliary rail 41 divided into four parts (Fig. 7,
A large number of bolt holes 42 are formed for attaching (see Figure 0), and auxiliary rails 41 are attached to the lower surface of the top plate 39 symmetrically in the front and back.

At each corner of the top plate 39, a mounting portion 45 is formed to attach a travel aid plate mounting block 44 for supporting the travel aid plate 43 shown in FIG. A bolt hole 46 for screwing the block 44 is provided.

As shown in FIGS. 7 and 10, the auxiliary rail 41 is provided with a horizontal upper plate 47 in the shape of a regular square plate that directly contacts the top plate 39, and a lower part of the upper plate 47. a support plate 48 parallel to 47;
It is composed of a vertical connecting member 49 having an L-shaped cross section that connects the upper plate 47 and the support plate 48, and a guide piece 50 that forms the lower end of the connecting member 49 and projects downward from the support plate 48. The upper plate 47 covers the lower surface of the top plate 39 almost without any gaps, as shown in FIG.
As shown in FIG. 10, the suspension shaft 18
They are arranged at regular intervals so that cross-shaped grooves 51 are formed so that the cross-shaped grooves 51 can be passed through without contacting.

The traveling aid plate 43 is fixed to the four orthogonal corners of the hanger rail 16 like the support plate 48, but is fixed to the lower end portion of the traveling aid plate mounting block 44 by bolts 52. In the installed state, the upper surface of the travel auxiliary plate 43 is installed at a height that is on the same plane as the travel surface 17 of the hanger rail, and its tip 53 is located at a height where the upper surface of the travel auxiliary plate 43 forms the same surface as the travel surface 17 of the hanger rail 16. Since it protrudes in the direction of the groove 31' between the auxiliary plates 43, there is a possibility that the upper surface of the traveling auxiliary plate 43 and the lower end surface of the vertical wheel 12a perpendicular to the running direction of the hanging wheel traveling straight ahead may interfere with each other. Therefore, the running auxiliary plate 43
A groove 54 having an arcuate cross section and an appropriate depth is formed in the upper surface of the hanging wheel in the running direction of the hanging wheel.

Further, the installation height of the support plate 48 is such that the vertical wheels 12 are attached to the hanger rail 16 as shown in FIG.
When the ball 27 is rolling on the running surface 17 of the support plate 43 or the upper surface of the running auxiliary plate 43, the ball 27 does not come into contact with the upper surface of the support plate 48, and the height is such that a slight gap of, for example, 1 mm is created between the two. The hanging wheel main body 10 approaches the orthogonal part of the hanger rail 16, and the vertical wheels parallel to the running direction are aligned with the groove 54.
When the ball 27 enters the inside or passes over the groove 31' between the left and right traveling auxiliary plates 43, the ball 27 comes into contact with the upper surface of the support plate 48, and the load of the moving wall is supported by the support plate 48. It is configured as follows. The state in which the vertical wheel has thus fallen into groove 31' or groove 54 and ball 27 is in contact with the upper surface of support plate 48 is shown on the right side of FIG. 6 and in FIG. At this time, the depressed vertical wheel and groove 54
The height of the travel auxiliary plate 43 and the depth of the groove 54 are adjusted so that there is a gap of about 0.5 mm between the two.

Therefore, when the hanging wheel body 10 is running on the straight part of the hanger rail 16 as shown in the left half of FIG. 6, the balls 27 do not come into contact with the upper surface of the support plate 48 as described above, There is a slight gap between the two, and when the hanging wheel body 10 eventually reaches the center of the orthogonal part of the hanger rail, it rolls on the upper surface of the running auxiliary plate 43, which is on the same surface as the running surface 17 of the hanger rail. vertical wheels 12
c and 12d fall slightly into the groove 54, and as the hanging wheel main body 10 descends, the ball 27 is pushed into the support plate 4.
The load of the movable wall applied to the suspension wheel main body 10 is supported by the auxiliary wheels 20 . At this time, the vertical wheels 12c and 12 that fit into the groove 54
d and the groove 54, there is a slight gap as shown in the right half of FIG.
Due to this slight fall of the vertical wheels 12a, all the vertical wheels fall into the grooves 54, and resistance is applied to their movement in the front, back, left and right directions, and the operator is able to confirm that the hanging wheel main body 10 has come to the center of the orthogonal part. can be sensed. In this way, when the hanging wheel body 10 reaches the center of the orthogonal part of the hanger rail 16, the hanging wheel which had been unable to move in the direction perpendicular to the running direction due to the contact between the guide piece 50 and the guide ring 33. The main body 10 includes a guide wheel 33
However, since it is released from the contact state with the guide piece 50 at the center of the orthogonal part, it is in a state where it can run in any direction, front, back, left, or right, and the operator can push the hanging wheel main body in any direction. At this time, the vertical wheels will cross over the grooves 54 of the travel auxiliary plate 43,
Although the operator feels some resistance, most of the load of the moving wall is acting on the support plate 48 via the balls 27 as described above, and the vertical wheels 12 do not completely fit into the grooves 54. Therefore, it is possible to escape from the groove 54 extremely easily, and the inconvenience of the vertical wheel falling into the groove 31' between the auxiliary running plates 43, 43 and giving an impact to the suspended vehicle is avoided. Ru.

As described above, the present invention has a plurality of vertical wheels attached to each of the four sides of a suspension wheel body having a substantially right-angled hexahedral shape at a height that touches the same horizontal plane, and an axis of a vertical shaft provided at the axis of the suspension wheel body. A single auxiliary wheel is attached around the core, and includes a horizontal and annular ball receiving member and a plurality of balls that roll in contact with the lower surface of the ball receiving member in an annular manner;
Attaching running auxiliary plates having the same surface height as the running surface to the four corners of the orthogonal part of the hanger rail having a running surface that forms the running track of the vertical wheels, and attaching running auxiliary plates perpendicular to the running direction to the upper surface of the running auxiliary plates. Traveling control of a hanging wheel for a movable wall, characterized in that an arcuate groove into which a wheel is loosely fitted is formed, and flat support bodies forming a running surface of the auxiliary wheels are attached above the four corners of the orthogonal part. Because it is a device, the vertical wheels at the orthogonal part of the hanger rail can maintain an extremely smooth running condition without falling into the cut (groove) of the hanger rail, and can freely move in any direction. The degree of freedom in transporting and arranging the movable wall is improved at once.

In addition, as a suspension means for a hanging vehicle, there is a method that uses only the auxiliary wheels used in the embodiment of the present invention and does not use vertical wheels. The load of the entire moving wall will be applied to the training wheels, but if you constantly apply a high load to the training wheels, which are not suitable for high loads because they are originally point contacts, the training wheels may wear out prematurely or cause noise. It is not practical for heavy loads because it is large and may damage the hanger rail. In this respect, as described above, in the present invention, the vertical wheels support the high load of the moving wall when the wall is normally placed, fixed, or traveling straight, and the auxiliary wheels temporarily support the load only when the wall comes to the orthogonal part of the hanger rail. Because it is supported, damage to the auxiliary wheels is almost never a problem, and the hanger rails do not wear out, so inexpensive aluminum hanger rails can be used, which increases durability and
This control device is extremely practical in terms of both cost and cost.
