Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a technology for a fishing wheel and a traveling rail A that hangs and moves a wall spring A (hereinafter referred to as a panel) of a movable partition, and particularly relates to a technique for a fishing wheel and a traveling rail A for moving a wall spring A (hereinafter referred to as a panel) of a movable partition, particularly in a direction perpendicular to the moving spring A. This relates to the technology of direction change.

Conventionally, a traveling bar 4AK fishing wheel with a C installed above the room was loaded, the stiffness C/<4A was lowered and set up, one spring A was moved, and Once the panels have been unraveled and set up, they are gathered in a corner of the room, and the front panels of the panels are placed next to each other and stacked one on top of the other.
When housing this spring A, the direction to the spring is changed by 90 degrees, and the fishing cart runs on two parallel travel rails A, front and rear, and curves at a gentle RII at the C1 intersection (branch point). There are two methods: a crooked traveling method using the running and hitting-h, and a cross traveling method in which the traveling rails are crossed at right angles.
In both methods, radial ball bearings of rolling balls are used as multiple wheels, but for bending travel, the wheels are used perpendicular to the fishing shaft, but for cross travel, [ Two wheels are used horizontally. latter t
J. This is the one in Figure 7 of the drawings, which is a horizontal two-wheeled fishing vehicle.
The former is a vertical two-wheeled vehicle. The present invention relates to a cross-travel method, and therefore the example shown in FIG. 7 will be treated as the prior art. This traveling rail A Gj '' has upper and lower two-layer wheel sheaths each housing the wheels of a horizontal two-wheeled fishing wheel, and one side of the opposing wheel bottoms is provided with a plate-shaped inclined surface and vertically staggered, and the lower end of the horizontal wheel. The part is supported on an inclined surface and rotated horizontally.

The fishing shaft that descends perpendicularly from the wheel can easily slide between the sliding grooves, which are the downward openings of the traveling rail h, and the opening of the sliding groove at the intersection of the traveling rail A. cross,
Even if the bottom of the wheel is cut off, a vertical two-wheeled vehicle has wheels on both sides of the sliding groove, and there is a risk that the wheel may fall into the sliding groove at an intersection when changing direction. Although various means are required, no additional means are required. Therefore, the technique shown in FIG. 7 is considered to be the most logical for cross travel where the travel rays A intersect at right angles.

However, its drawback is that it does not use radial ball bearing wheels like the vertical two-wheeled vehicle.
In other words, as mentioned above, only the lower end of the horizontal wheel is supported, and the weight of the suspended panel is supported unevenly, so even if the upper and lower wheel sheaths are supported alternately, the balance is not maintained. It collapses easily and it is difficult to keep the wheels at horizontal C. In addition, even when spring A is running straight, due to the structure described above, it tends to swing left and right, and when moving horizontally as shown in Figure 8, Gj, and as shown in Figure 9, the lower part protrudes and moves diagonally. Because of this, there are many failures in fishing wheels, including those with radial ball bearings.

Furthermore, at the cross section of the traveling rail A, the opening is wide because the sliding grooves normally intersect (Fig. 2).
. For this reason, the wheels of the horizontal two-wheel fishing cart are supported down a slope, and in addition, there is a step between the sloped wheel bottom and the flat wheel bottom, which makes cross running smoother. There is a drawback that it is impossible to prevent. The fact that the wheel sheath is formed in two layers also complicates the relationship between the cross section and the wheels, and most failures of fishing wheels occur at the cross section. Regarding the above-mentioned step, the slope of the slope is shaved to create a gentle step, but the installation work of the travel rail A at the cross section is extremely difficult.
In particular, there is a risk of weakening the strength of the running rail (strength of the cross section).

Furthermore, using radial ball bearings, which are normally used for vertical rotation, for horizontal rotation has a problem with the gravity bearing capacity of fishing wheels. 300Kg or more), the disadvantage is that the burden force is weak.

In this way, in the conventional moving panel cross traveling device,
There are many points of dissatisfaction, and it is thought that it is difficult to sufficiently eliminate the shortcomings by mere improvement, but in this invention,
Separate the wheels of the radial ball bearings, devise a conical and rigid rotating ring, and set the warp on the same plane and sandwich the sliding groove.
The structure of the running rail has a simple shape with a layer of wheel sheaths, and the number of contact points between the wheel bottom and the rotating wheel has been increased to four, making the fishing trolley stable while traveling. In addition, in preparation for the downward movement of the contact point at the cross section, the problem was solved by supporting the tip of the rotating wheel of the downward conical body by providing a guide bottom.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. A cross traveling device for a moving spring A according to the present invention includes a fishing wheel 1 made of a hard material such as metal and a traveling rail A2 (FIG. 1). As seen in FIG. 5, the fishing wheel 1 has a main body 3, which is a small part in the shape of a flat regular rectangular prism, with a fishing shaft hole 5 in the center of which a fishing shaft 4 is inserted vertically extending from the top surface to the bottom surface with a circular cross section. Penetrate and open. The upper end of this fishing shaft hole 5 may be further notched and the flat cylindrical C may be enlarged slightly to form a circle 6.

The main body 6 is further provided with four axle holes 8 having a circular cross section and extending vertically from the top surface to the bottom surface with the circular surface 6 as the center. , the axis 7, which is the center point of the circle, is located on the diagonal of the square cross section of the main body 3, and is located at a symmetrical position with respect to the fishing axis hole 5. The lower end of the axle hole 8 is further expanded and cut into a slightly larger flat cylindrical shape to form a bearing surface 9.

On the other hand, a conical wheel 12 has a cylindrical axle 11 projecting at right angles from the center of the upper surface of a downward conical body 10 with a gently rounded tip. The axle 10J1 said axle 68
It is of a size that can be inserted into the axle hole 8, and is slightly longer than the vertical length of the axle hole 8.

A rolling ball 1 is placed on the upper surface of the cone body 10 of this conical wheel 12.
A radial ball bearing 14 with 6 oriented vertically is arranged horizontally, and the axle 11 of the conical wheel 12 is placed C upward and inserted into the axle hole 8 from the lower surface of the main body 3, respectively. In this case, radial ball bearing 144! The axle 11 is housed in the bearing surface 9 of the main body 3, and the tip of the axle 11 slightly protrudes upward (FIG. 3).

This tip is fixed with a clip washer 15, and the conical wheel 12.12.12.12 is rotatably fixed to the main body 3.

The conical wheel rotates in the horizontal direction C.

On the other hand, a flat cylindrical head 17 is provided on the distal end surface of the cylindrical body 10.
Bring the fishing shaft 4, which is sized to fit inside the circumference 6, into the fishing shaft hole 5C on the upper surface of the main body 3, insert it into the fishing shaft hole 5 with the circular body 16 first, and protrude from the lower surface. and bring the head 17 into contact with the upper surface (FIGS. 1 and 4). When the main body 3 has the same amount 6, the head 17 fits inside the circular plate 6.

In this state, the fishing shaft 4 is rotatably attached to the main body 3.

The above is the structure of the fishing wheel 1. Figure 4 shows the fishing wheel 1.
This is a view from below.

Next, in the traveling rail A21rJ, an oblong member with a cross-section of a mouth-shaped opening facing downward, both open ends of the mouth-shape are made to protrude horizontally inward at right angles into the small part to form the wheel bottom 18.18. ing. Furthermore, the open end of the wheel bottom 18 is made to protrude outward at a right angle. protrusion length +i, said conical wheel 12
The length shall be equal to the height of the cone 10. Furthermore, the open tip of the protruding portion is made to protrude inward at right angles, leaving the sliding groove 19 in which the fishing shaft 4 slides in the center and laterally of the opening of the U-shaped cross section of the oblong member. This is referred to as the guide protrusion 20.20. The hollow portion inside the traveling rail 42 in this state is defined as the wheel sheath 21.

Wheels? : C. The fishing wheel 1 is made to be large enough to accommodate the fishing wheel 1, with a little space left above.

The above is the structure of the traveling lane A2.

Next, how to use the present invention will be explained with reference to FIGS. 1, 2, and 6.

Above the room, there is a running rail 2.2. .
The fishing shaft 4 is suspended between the sliding grooves 19, and the cone 10.1 is attached to the protrusion 22.22.22.22 of the wheel bottom 18.
0.10, + The ONS part is supported, and the tip of the cone 10 is slightly lifted from the guide bottom 20 (in the example, kl
L 2 mm) installed and two fishing wheels 1.1 fishing shaft 4
．． The tip of #4 is rotatably connected to the upper end surface of spring A25, so that spring #A25 is hooked onto traveling rail A2. Regarding the movement of the fishing equipment pa4A25, the traveling lane A2.2. , , the conical wheels 12 of the fishing wheel 1.1, +2 . , , are rotated on the protrusion 22 of the wheel bottom 18 to travel. In the cross travel at the cross section 24 intersecting at right angles to the travel lane A2.2, the conical wheel 12 of the fishing wheel 1 is moved onto its protrusion 22.22 to the wheel bottom +8, +8 in the changing direction, as in straight travel. At the same time, the tip of the cone 10 of the C fishing wheel 1 is rotated to the guide bottom 20° 20.2 of the traveling ray A2 at the cross portion 24.
It is supported at a ratio of 0:20 to achieve cross travel.

According to the present invention, all the drawbacks observed in the horizontal two-wheeled fishing wheel 25 and the two-layer (with inclined surface) traveling rail A'' 26 of the conventional examples are eliminated. That is, it has a flat and stable shape. In its own body 3, this A ball bearing 14 can function sufficiently to rotate the conical wheel 12, even if it is not used in its original use.

The two conical wheels 12 are opposed to each other with a sliding groove 19 in between, and the main body 3 fits within the width of the running rail 2 C1, so that running and fishing within the rail 2 are not possible. The aforementioned rocking of the car 1 does not occur at all.

In the present invention, the radial A ball bearing 14 is not used as a rotating wheel, and the gravitational force borne by the horizontal two-wheel fishing wheel 25 is several times that of the horizontal two-wheeled fishing wheel 25 for the fishing installation and movement of the fishing wheel 23.

When the fishing wheel 1 travels straight C on the traveling ray A2, the slope of the conical body 10, which is the rotating wheel portion of the conical wheel 12, contacts the - point along the line of the protrusion 22 of the traveling ray A2. Since the rotation progresses while rotating, there is little friction, and stable and smooth running can be achieved due to the guidance of the right-angled protrusion 22. At the cross section 24 of the running rail A2.2, the opening of the running rail 42 is widened due to the intersection of the sliding grooves 19, so that the contact slope of the conical wheel 12 that comes into contact with the protrusion 22 of the wheel bottom 18 increases. For example, it shows a drop of about 1 to 2 mm.

In the conventional horizontal two-wheeled fishing wheel 25, the above-mentioned inclined surface 27
When the radial ball bearing ring 28 descends with a creaking sound, the cross portion 24 swings back and forth, left, right, up and down, and it is difficult to maintain the wheel horizontally. In the above-mentioned lowering of the fishing wheel NJ and the conical body 10, the rounded tip of the conical body 10 is supported by the guide bottom 20 of the running rail 2, so that the above-mentioned trouble of the cross portion 24 does not occur.

Furthermore, as seen in FIGS. 2 and 6, a conical wheel 12.
12, I2.12 is also in a state where it can directly face and be tangential to the wheel bottom 18.18 in the traveling direction (notch direction) at the cross portion 24, and is extremely suitable for cross traveling by folding at a right angle. It is a flight. Moreover, in the present invention, the wheel bottom 184'
J is a flat protruding surface, and a difference in level due to the intersection of the first inclined surface 27 and the flat surface 2B does not occur in the cross portion 24 as in the two-layer traveling rail A26.

For this reason, the swaying when going up or down a slope,
In particular, no thrust force (Fig. 9) to be applied to the spring A23 is required.

In the present invention, the lower part of the spring A23 does not protrude or swing at all during the lateral movement of the pawl 23 (FIGS. 8 and 9).

The traveling rail A2 of the present invention has a simple structure as described above, and since the wheel bottom 18 does not have an inclined surface 27 or a special shape, it is easy to butt and join the ends at the cross section 24. , without any difficulty. As seen in FIGS. 2 and 6, the orthogonal formation of one wheel sole 18, 18 with a continuous flat surface is easily accomplished.

Therefore, the structures of the fishing wheel 1 and the traveling rail A2 are reasonably solid, and there is little chance of an accident due to breakdown or the like.

As described above, the present invention is based on a novel idea, brings about outstanding effects, and has high industrial applicability.
