Description

[Detailed description of the invention] (Industrial application field) This invention is a fishing wheel device in which a movable partition wall panel (hereinafter referred to as a panel) is hung on a traveling rail by a fishing wheel and moved (traveled). It relates to the technology of a two-layer horizontal wheel fishing wheel using horizontal wheels in two layers, upper and lower, and its running rail, and also to intersection rails formed by crossing the running rails at right angles to each other, and especially its three-way intersection. Regarding rails.

(Prior art) Conventionally, for the installation and movement of panels, a wheel was used in which both open ends of a rail material with a U-shape with a downward opening in cross section were bent inward at right angles, leaving a sliding groove in the center of the end. A running rail with a bottom is laid on the ceiling, and the wheels of the fishing wheel, which rotate in a vertical plane like the wheels of a cart, are placed inside the running rail (wheel sheath) and placed on the bottom of the wheel, and the fishing shaft is slid. A fishing wheel device with vertical wheels that hangs from the chassis in a groove and connects the upper end surface of the panel to a fishing shaft, and a fishing wheel device with horizontal wheels that attaches a horizontal wheel directly to the fishing shaft and further connects the panel to the fishing shaft. There is.

In the latter type of horizontal wheel fishing wheel device, there are two types of fishing wheels: one in which the horizontal wheels are arranged in two layers, upper and lower, and one in which the horizontal wheels are arranged in a single layer and placed on two wheels on the left and right. The wheel bottom has a triangular cross section and is inclined toward the sliding groove.

The present invention relates to the latter type of horizontal wheel fishing wheel device, and also relates to one in which the horizontal wheels are arranged in two layers, upper and lower. Now, this generally relates to fishing wheel devices in general, but the technology for changing the direction of panels by crossing traveling rails is still considered insufficient.

Changing the direction involves moving panels to create new partitions or eliminate them.
This is done by moving panels along running rails, and is considered indispensable especially in Japan compared to Europe and America.

Now, most fishing carts cannot easily proceed at intersections of running rails where direction changes are made. This is because at the intersection of the running rails, the wheel bottoms are cut off due to the intersection of the sliding grooves, and the wheel sheaths of the running rails, which had accommodated the fishing wheel almost to their full length, become enlarged at the intersections. It is. As a result, the function of the regulating walls that restricted the left and right movement of the fishing wheel is lost, and the fishing wheel suddenly becomes unstable.

In a horizontal wheel fishing wheel device, at an intersection, the horizontal wheels reach the center of the intersection by slightly descending on the inclined surface of the bottom of the wheel that supports them. However, even though it descends slightly, in order for the fishing cart to pass through the intersection, the horizontal wheels must rise, albeit slightly, and for this reason, particularly heavy panels are installed. In this case, they were to face great difficulties. This caused an even more serious situation in the case of fishing carts with double-layered wheels. That is, unlike in the case of a single-layer four-wheel horizontal wheel fishing cart, the wheel soles are staggered in the upper and lower wheel sheaths, and at an intersection the wheel soles are located at one corner of the upper or lower wheel sheath (of a three-way intersection). This is because a cut-off portion occurs at the two corners (in the case of a four-way intersection) and the horizontal wheels are unevenly obstructed.

For this reason, the applicant eliminated the shape of the wheel bottom of the running rail from an inclined surface with a triangular cross-section, and changed it to one with a flat upper surface and a narrow width of 2 to 3 mm, so that the running rail intersects at right angles. In the intersection rail, a protruding wheel bottom is formed that protrudes toward the intersection, and this is an epoch-making problem solved in a two-layer horizontal wheel fishing wheel device. This is a new idea for the intersection rail.

That is, in the conventional three-way intersection rail according to the invention, the upper and lower wheel bottoms alternately intersect with the center line of the intersection toward the bending side, as shown in FIG. The same technology used to stagger the top and bottom of the fishing cart's running rails has also been applied to the rails at three-way intersections. However, as shown in Figure 8, the intersection rail of a three-way intersection constitutes the outer periphery of a ceiling installed vertically and horizontally, or when a suspended panel is accommodated in one corner as shown in Figure 7. In the case of forming the outer periphery of the former, as the wheels move along the outer periphery, the horizontal wheels will change the direction of rotation and rotate in the opposite direction as they come into contact with the bottoms of the wheels that are alternated up and down at each three-way intersection. . In the latter case, as shown in FIG. 7, the accommodating portions cannot be unified to one side as they are, but as shown in the left and right side views of FIG. 5, the accommodating portions are on opposite sides. The present invention is a new invention regarding the outer circumferential portion and the housing portion of the above-mentioned invention.

(Structure of the present invention) The present invention has two to two layers of horizontal wheels on the upper surface of the bottom of the running rail that accommodates the fishing wheel with two-layer horizontal wheels.
The top or bottom of the upper or lower In either one of the wheel sheaths, on the straight-ahead side, the restriction wall and the wheel bottom are connected to each other to form a straight line, and from the wheel bottom at the joint (center of the intersection), towards both corners on the bending side. The protruding wheel bottom protrudes above the wheel holder projection, and on the bending side, a regulating wall and the wheel bottom are provided from either one of the corners toward the bending direction, and on the other wheel sheath, on the straight-ahead side, the wheel holder protrusion On the bending side, a restriction wall and a wheel bottom are provided on the side parallel to the straight-ahead side, and a restriction wall and a wheel bottom are provided on the side opposite to the side where the protruding wheel bottom is provided in the first wheel sheath. The bottom is extended in the bending direction, and the protruding wheel bottoms are made to protrude from the wheel bottoms at both corners to form a three-way intersection rail, eliminating the alternating upper and lower opposition of the wheel bottoms on the straight side. .

(Example) In order to explain the present invention in detail, the same will be described below with reference to the accompanying drawings.

FIG. 1 shows a running rail 1 and a fishing wheel 2 with two-layer horizontal wheels.

The running rail 1 is a U-shaped elongated member 3 with a downward opening in cross section, with both open ends oriented inwardly at right angles.
Leaving a sliding groove 5 on which the fishing shaft 4 of the two-layer horizontal wheeled fishing wheel 2 slides in the center of the tip, the wheel holder protrusion 6 is made to protrude from the center of the left and right sides 7, 7 of the U-shape. Similarly to the above, the sliding groove 5 is left at the front center at right angles inward, and the wheel receiver protrusion 6 is made to protrude to form upper and lower two-layer wheel sheaths 8,8. Furthermore, on a pair of wheel support protrusions 6 that are arranged vertically in an alternating manner, a wheel bottom 9 and a small wall body rising from the upper surface 10 of the wheel bottom 9 on the side 7 side are arranged inwardly at right angles from the side 7. The regulating wall 11 is made to protrude integrally. The upper surface 1 of the wheel bottom 9
0 should be flat with a small width of 2 to 3 mm.

The two-layer horizontal wheel fishing wheel 2 is made by horizontally fixing two upper and lower horizontal wheels 12, 12 to the fishing shaft 4 in a vertical state, and as shown in FIG. Almost completely accommodated in the cross section of 1,
The lower end surface 13 of the horizontal wheel 12 is placed on the upper surface 10 of the wheel bottom 9 of the traveling rail 1, the side end surface 14 thereof is brought close to the regulating wall 11, and when traveling, it rotates due to surface friction between the lower end surface 13 and the upper surface 10, It advances with the side end surface 14 along the regulating wall 11.

The three-way intersection rail 15 of the present invention has a shape in which the traveling rails 1, 1 intersect with each other at right angles, and the wheel receiving protrusions 6, 6 are connected to each other to form a three-way intersection.

In the above state, on the straight-ahead side 16 of either the upper or lower wheel sheath 8 (lower wheel sheath 8 in FIG. 3), there is a restriction wall 11 and a wheel bottom 9.
are joined at the intersection 17 in a butt-like manner, and the wheel bottom 9 is extended and provided on the joined wheel receiver protrusion 6,
Wheel bottoms 21a, 21a are formed in a straight or curved shape to project from the wheel bottom 9 at the center 18 of the intersection 17 toward both corners 20, 20 located across the sliding groove 5. Further, on the bending side 19, the regulating wall 11 and the wheel bottom 9 are provided integrally extending from the corner 20 on either the left or right side toward the bending direction on the wheel support protrusion 6, and the corner of the wheel bottom 9 is provided. A protruding wheel bottom 21b is integrally protruded from the corner 20 toward the protruding tip portion 22 of the combined wheel receiver protrusions 6,6.

On the straight-ahead side 16 of the other wheel sheath (the upper wheel sheath 8 in FIG. 2), the wheel receiver protrusions 6, 6 are continuous and are not provided with the wheel bottom 9 and the regulating wall 11.

Further, on the bending side 19, a regulating wall 11 and a wheel bottom 9 are provided on a side 23 parallel to the straight traveling side 16 so as to extend integrally above the wheel receiver projection 6, and the first wheel sheath 8 (lower part shown in FIG. 3) is provided. At the corner 20 on the opposite side of the wheel sheath 8) where the protruding wheel bottom 21b is provided, the regulating wall 11 and the wheel bottom 9 are extended in the bending direction and are integrally provided on the wheel receiver protrusion 6, and From the wheel bottoms 9, 9 of the wheel bottoms 20, 20, the wheel bottoms 2 project integrally with the projecting tips 22, 22 of the combined wheel receiver projecting parts 6, 6.
1b and 21b are made to protrude.

In addition, the protruding wheel bottoms 21a, 21b... align the top surfaces 10, 10 with the wheel bottom 9 connected thereto,
Align the tip with the wheel holder protrusion 6, and
4, 24... are shaved off diagonally toward the wheel receiver protrusion 6 to form tapered surfaces 25, 25... (FIG. 6). What is constructed as described above is the three-way intersection rail 15 of the present invention.

(Effects of the invention) Comparing the effects of the invention with the prior art described above, the invention shows that the horizontal wheels 12, 12 are supported by the wheel bottom 9 and the protruding wheel bottom 21 without being biased at the intersection 17 of the three-way intersection. However, in the conventional technology shown in FIG. 5, when the direction is changed to the turning side 19 at the intersection 17, the rotation direction of the horizontal wheel 12 does not change, whereas the direction of rotation of the horizontal wheel 12 does not change when changing direction to the turning side 19 at the intersection 17. 16 (and the parallel side 23), the direction of rotation of the horizontal wheels 12 changes (the horizontal wheels 12 temporarily stop rotating). On the other hand,
In the present invention shown in FIG. 4, the direction of rotation of the horizontal wheel 12 changes when changing direction from the right side of the figure to the bending side 19, but when the horizontal wheel 12 rotates on the straight side 16 (and the side 23 parallel to this), the horizontal wheel 12 changes direction. The direction of rotation of 12 remains unchanged.

For this reason, if the three-way intersection rails 15, 15, . . . of the present invention are arranged on the outer peripheral portion 27 in FIG.
Progress in the outer peripheral portion 27 can be made extremely smoothly. Also, the comparison is made when the accommodating portions 28 and 28 are used facing each other, and in contrast to the prior art shown in FIG. As shown in Figure 4, the left and right side views B are located on the same side, and the 7th
As can be seen in the figure, the receptacles 28, 28 can be formed on the same side, so that a tidy room can be provided in front. Note that the reference numeral 29 in the drawings indicates a panel.

In the present invention, the outer circumferential portion 27 is
Not only can it be used for the housing section 28, but it can also be used in conjunction with a conventional three-way intersection rail.
This contributes to making the movement of the panel 29 (installation and removal of partitions) by the traveling rail 1 more versatile and effective.

Note that the upper surface 10 of the wheel sole 9 and the protruding wheel sole 21 is made into a flat surface and the conventional triangular inclined wheel sole is abolished, but the horizontal wheel 12 is supported by a narrow portion of 2 to 3 mm on the upper surface 10. is stable, and even with surface friction, the rotation of the horizontal wheel 12 is as good as that of the conventional one, and is particularly superior to the heavy-duty panel 29.
