Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable wall suspension vehicle for moving a movable wall used as a room partition while hanging on the ceiling, and for transporting and placing the movable wall at an arbitrary position. The present invention relates to a highly practical movable wall hanger that can run without impact on orthogonal parts of hanger rails laid in a matrix and can freely change the running direction.

In order to transport the movable wall to any desired position and freely partition the room, hanger rails, which are the travel locus of the hanging wheels, must be laid vertically and horizontally on the ceiling. If the hanger rails are laid vertically and horizontally, the hanger rails will inevitably intersect, causing various problems in that area.

One of them is that such intersections require a cut in the hanger rail through which the shaft of the hanger that suspends the moving wall from the hanging wheel passes, but when passing through the intersection, the wheels of the hanging wheel pass through this cut. The problem is that it falls off and applies a large impact to the moving wall, damaging the moving wall, the hanging wheel, and even the hanger rail.

In addition, the running direction of the movable wall suspension must be changed at this intersection, but conventional equipment requires a rotary device that rotates the entire intersection, a complicated branching rail, and a control device for the running direction. In addition, various types of suspension wheels were required, such as one for turning and one for straight travel, making it difficult to control travel as needed.

The present invention relates to a special movable wall hanging wheel that solves all the problems inherent in the conventional hanging wheels as described above. Two vertical wheels are disposed on each of the front, rear, left, and right side walls of the hanging wheel body, and the vertical wheels are eccentric to the left and right from a central plane that passes through the axis of the movable wall hanging shaft and is perpendicular to each side wall, The purpose of the present invention is to provide a hanging wheel for a movable wall, characterized in that one vertical auxiliary wheel eccentric to one side from the central plane is attached to the intermediate portion of both vertical wheels provided on each of the side walls.

Next, embodiments embodying the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a perspective view of a movable wall hanging wheel according to an embodiment of the present invention, and FIG. 2 is a front view of the hanging wheel including a hanger rail showing the running state of the hanging wheel (the side view is the same as the front view). Figure 3 is a plan view showing the running state of the hanging vehicle at the orthogonal part of the hanger rail;
FIG. 4 is a side view showing the running state of the hanging vehicle at the orthogonal section of the hanger rail.

In Figures 1 to 3, (1) is the suspension wheel body, and the third
As is clear from the plan view shown in the figure, there are hanger rails (3) on the front and rear surfaces (2a) (2b) and the left and right sides (2C) (2d), which have a right quadrilateral cross section and are orthogonal to each other.
Two vertical wheels rolling on a running surface (4) are rotatably mounted. The hanging wheel main body (1) has a hanging shaft (5) in the vertical direction for hanging the movable wall in the center thereof, and the hanging shaft is connected to a vertical hole (69) bored in the center of the hanging wheel main body. is inserted into the vertical hole (6), and its head (7) is inserted into the vertical hole (6).
), and is prevented from coming off upward by a lid (9) screwed onto the top of the step. It is designed to be able to rotate freely around its axis, but not to move in the vertical direction.

The two vertical wheels attached to each side are each attached at a position offset from the center of the hanging shaft by a certain distance. For example, as shown in FIG. ) from the central plane (12A) perpendicular to
) are installed so that they do not interfere with each other. This eccentric heat resistance (l) is caused by the arcuate grooves (13a) bored in the running distances (4a) and (4b) of the hanger rail by the vertical wheels (10a) and (10b) in the running state shown in FIG. The value is such that it is placed directly above (13b). The same goes for the two vertical wheels attached to the other sides of the hanging wheel body (1), that is, the rear and left and right sides, and the two vertical wheels are attached to the center surface (12A) and (12A), respectively.
It is rotatably mounted at a position eccentrically equidistant from 2B).

One vertical auxiliary wheel is rotatably attached to each of the front, rear, left, and right side walls of the hanging wheel main body (1) at the intermediate portion of the left and right vertical wheels. That is, as shown in Fig. 3, each vertical subwheel (33a) (33b) (33c) (33d) is installed in a position that does not interfere with the vertical wheels on both sides, and the flat surface is sunken from the front and rear sides (2a) (2b). (2a') (2b'
) The vertical secondary wheels (33a) (33b) attached to
The left and right side surfaces (2c) and (2d) are installed at positions eccentric to the left and right by a distance (l1) from the center plane (12A), respectively.
) The vertical subwheels (33c) and (33d) attached to the planes (2c') and (2d') depressed from the central plane (12
They are installed at eccentric positions front and rear by a distance of (l1) from B). The mounting heights of these eight vertical wheels and four vertical sub-wheels are determined so that they all run on the same plane as shown in FIG. Therefore, as shown in Figure 2, the vertical carriages (1Oc) and (10d) installed on the left stone side (2c) and (2d)
The running surfaces (4a) and (4a) of the hanger rail are on the same plane.
41b) when traveling in a direction perpendicular to the paper surface,
Vertical wheels (10) provided on the front and rear sides (2a) and (2b)
a) and (10b) are located directly above the arcuate grooves (13a) and (13b) bored in the running surface (4a) and the mosquito fin (4b), and are perpendicular to the bottoms of these grooves (13a) and (13b). Since there are gaps (14a) and (14b) between the wheels (10a) and (10a) that correspond to the depth of the grooves, there is a gap between the vertical wheels (10a) and (10a) and the hanger rail. Interference is avoided, and the movable wall main body (1) runs smoothly in a direction perpendicular to the plane of the paper by means of vertical wheels (1Oc) and (10d) provided on the left and right side walls. In addition, in this state, the vertical secondary wheels (33c) and (33d) provided on the left and right side surfaces (2c') and (2d') of the movable wall main body also touch the running surface (
4a) and (4b), but the front and rear surfaces (2a'
) and (2b') vertical subwheels (33a) and (3
3b) is the running direction of the hanger rail (4a) and (
4b), which is the passing part of the hanging shaft (5), and is suspended in the air, so interference with the hanger rail is avoided. Does not prevent the moving wall from running smoothly.

The hanger rail (3) has the aforementioned running directions (4a) and (4b) and the side walls (15a) and (15) connected thereto.
b) and an upper wall (16) connecting both side walls at the upper part.
), and the cross section as a whole has a substantially C-shape as shown in FIG. At the center of the lower surface of the upper wall (16), a guide wall (17) that is integral with the upper wall is formed continuously in the longitudinal direction, and a rotatable guide wall (17) that is arranged in a square shape on the upper surface (18) of the hanging wheel body is formed. Horizontal wheel (19a) (19
b) (19c) and (19d) are arranged so as to sandwich the guide wall (17) and come into contact with the guide wall (17) through a slight gap.

The side walls (15a) and (15) of the hanger rail (3)
b) is bent (20) in the left-right direction as shown in FIG.
) and (21b) with vertical wheels (1Oc) and (10d)
are inserted into the upper surfaces (22) and (22) of the recesses (21a) and (21b) in the running state shown in the figure.
) and the upper surfaces of the vertical wheels (1Oc) and (10d), there are slight gaps (23) and (23).

Therefore, even if a force in a direction perpendicular to the plane of the paper in FIG. ) and prevents the hanging wheel from moving up, preventing the moving wall from tilting and stabilizing its running condition. Also, when a rotational force is applied to the moving wall in the left-right direction as shown by the arrows, the vertical wheel on the side that is trying to lift due to this force will
By coming into contact with the upper surface of the concave portion and preventing it from floating up, and at the same time, the horizontal wheels (19a) and the like also come into contact with the guide wall (17), thereby preventing the hanging wheel from tilting in the left-right direction and allowing the movable wall to run stably. Secured.

Next, the running state of the hanging wheel will be explained.

When this suspended vehicle travels in the front-back direction as described above,
The front and rear vertical wheels (10a) and (10b) have circular grooves (
13a) and (13b), there is no contact with the running surfaces (4a) and (4b), and the left and right vertical wheels (10c) and (10d) are in rolling contact with the running surfaces (4a) and (4b). Run smoothly. Similarly, when the hanging wheel runs in the left and right direction, the front and rear vertical wheels (10a) and (10
b) is in rolling contact with the running surface of the hanger rail in the left and right direction, and runs in a state where the left and right vertical wheels are separated from the running surface due to the presence of an arc state in the left and right direction of force. At that time, the running surface (4a
) and (4b).
), a hanging shaft (5) is pushed through without contact, and a movable wall (not shown) suspended from this hanging shaft moves along the hanger rail as the hanging wheel travels. Horizontal wheel (1
9a) (19b), etc., as described above, the guide wall (17
) and rotates while in contact with this guide wall to maintain the straight running state of the movable wall.

When the movable wall approaches the orthogonal part of the hanger rail shown in Fig. 4, the vertical wheel (10a1) on the front side in the running direction, indicated by the arrow (35) as shown in the figure, first hits the cut rI of the running surface.
The vertical wheels (33a) and (33b) attached between the front and rear vertical wheels (10a1) and (10d2) are in the running direction (4x
) and receives the load applied to the central suspension shaft (5), the front vertical wheel (10a1) maintains the running state without falling into the cut (34). As the hanging wheel moves further forward, the front vertical secondary wheel (33a) approaches the cut (34), but since the vertical secondary wheel (33b) is provided at a position eccentric to the rear of the central plane (12A), at this point However, the vertical secondary wheel (33b) is on the running surface, and the suspension shaft (5
), the tilting of the hanging wheel itself is continuously prevented. When the rear vertical secondary wheel (33b) approaches the cut (34), the front vertical wheel (1
0a1) crosses the cut (34) and crosses the cut (34).
(5) on the front end of the running surface (4y) on the opposite side while holding the
At this point, the load of the moving wall is completely supported by the vertical wheels (10a1) and (10a2), and the tilting of the hanging wheel body is prevented.

In this way, as the suspended wheel main body further moves forward, both vertical wheels enter the arcuate grooves (13a) and (13b), and the traveling of the suspended wheel temporarily stops. Vertical wheels like this (10a1)
and (10a2) are circular arc grooves (13b) and (13a
), the entire hanging wheel body sinks downward by the depth of the arc-shaped groove (13), and therefore the left and right hanger rails, which had previously been lifted from the hanger rail by the depth of the arc-shaped groove, The vertical wheels (10c) and (10d) also come into contact with the longitudinal grooves (13c) and (13d), and all eight vertical wheels contact the bottom of the arcuate groove, so the hanging wheel body It is supported by vertical wheels. The state in which all the vertical wheels have entered the arc-shaped girdle is the state in which the hanging wheel has arrived at the orthogonal part of the hanger rail as shown in FIGS. 1 and 3. Therefore,
Next, even if force is applied to the moving wall in either the left-right direction or the front-back direction, the hanging wheel body will start traveling in the direction of that force, and it can change direction in any direction. . The hanging wheel, which has started traveling from the state shown in FIG. 3, undergoes an operation completely opposite to that shown in FIG. 4, and then starts traveling straight in the direction of the hanger rail to which the force is applied.

In a further improved structure of the above embodiment, a disk-shaped thrust washer (25) made of synthetic resin with a low coefficient of friction is fixed on the lower surface (24) of the suspension wheel body around the suspension shaft (5). will be established. In the running condition shown in Fig. 2, the lower surface (36) of this thrust washer (25) and the running surface (4)
There is a slight gap (4) between them. This gap (
26) and the depth (δ) of the arc-shaped groove (13) are set to be the same or so that the depth (δ) of the arc-shaped groove (13) is slightly wider than the gap (26).

When such a thrust washer (25) is used, the running state at the orthogonal section is as follows:
and (10a2) arcuate grooves (13a) and (13b)
Before or at the same time, the lower surface (35) of the thrust washer (25) is inserted into the running surface (4x) and (4y
) and receives the load of the moving wall while sliding on the running surface, thereby preventing the suspension wheel from tilting due to unbalanced loads and alleviating the impact caused by the vertical wheel moving into the arcuate groove.

As described above, the present invention has a movable wall hanging shaft vertically attached to the center of the hanging wheel main body, two vertical wheels arranged on each of the front, rear, left and right side walls of the hanging wheel main body, and the vertical wheels are connected to the In addition to passing through the axis of the movable wall hanging shaft and eccentric to the left and right from a plane perpendicular to each side wall, there is also a vertical sub-wheel located in the middle of both vertical wheels provided on each side wall, which is eccentric to one side of the central plane. Since this mobile wall hanging vehicle is characterized by having wheels attached to it, when passing through the orthogonal part of the hanger rail, the wheel may fall off at the break in the rail and give a strong impact to the moving wall, etc. Moreover, after stopping at the perpendicular part of the hanger rail, the hanging wheel can easily change its direction of travel in any direction, allowing it to freely turn left, right, and go straight instead of only changing direction in one direction as in the past. The present invention provides an extremely economical and practical suspension wheel that is flexible, does not require expensive equipment such as a rotary device, and is extremely economical and practical.
