Accordingly, stability can be improved.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a movable partition wall panel (hereinafter referred to as a moving panel) that is suspended and travels (moves) by a suspension wheel, and technology for the suspension wheel, and further relates to a technology for a hanging wheel using a radial ball bearing. Related to wheel technology.

BACKGROUND ART A movable panel is moved along a running rail installed toward the ceiling, and by being moved, it can be guided to a panel storage area or used for setting up a new partition.

For this purpose, the upper end surface of the panel is rotatably fixed to the hanging shaft of the hanging wheel, and in most cases, a two-layer hanging wheel is attached to the front and back of the upper end surface, and the wheels of the hanging wheel are placed on the wheel bottom of the traveling rail. A hanging ring is hung vertically between the sliding grooves in the lower central opening of the travel rail, and the panel is suspended to form a movable panel.

For the wheels of the suspension wheel, building rotating wheels such as radial ball bearings or thrust ball bearings are used, which provide smooth running and have sufficient bearing capacity to bear the weight of the moving panel.

Of these, the rotating wheels for buildings with radial ball bearings are vertical wheels that rotate in the same direction as the hanging shaft of the hanging wheel, and vertical wheels that rotate at right angles to the hanging shaft.
Used as a horizontal wheel that rotates horizontally. A vertical wheel is a U-shaped horizontally elongated member with a downward facing frontage in vertical section, and the wheel bottom is horizontally projected from the side to the sliding groove. The horizontal wheel runs on a horizontal wheel bottom or a triangular wheel bottom inclined in the direction of the longitudinal sliding groove, while rotating like a helicopter rotor.

A horizontal wheel does not rotate unless a part or point of the lower end surface of the wheel is supported on the wheel bottom.

For this reason, the hanging wheel is provided with horizontal wheels in two layers, upper and lower, in order to maintain balance, and the running rail is provided with wheel bottoms of the above-mentioned shape in alternating upper and lower layers.

The present invention is a suspension wheel for a movable panel that uses this radial ball bearing rotating wheel for buildings as a horizontal wheel.

The movable panel is a panel with a height extending from above the floor to near the ceiling, and even the lightest one has a weight of over 100 kg. The suspension wheels used for moving panels, and therefore the building wheels, must be able to withstand this weight. Conventional hanging wheel devices (e.g. Utility Model Publication No. 53-24288)
(numbers, etc.) are shown in Figure 4 (b) of the attached drawings. The radial ball bearing rotary wheel for buildings used in Figure 4 (B) of the drawings has a very strong bearing force when used as a vertical wheel, as shown in Figure 4 (A).
It has a bearing force of 40 kg, but when used as a horizontal wheel, it only has a bearing force of 24 kg. In addition, since a horizontal wheel is used that is likely to cause balls (steel balls) to deviate from the ball hole even when used as a vertical wheel, ball deviation failures are extremely likely to occur.

On the other hand, rotating wheels for buildings with thrust ball bearings (No. 4 donkey in the drawing)
has a strong bearing force against vertical loads, and those with the same diameter have a bearing force of 1 or more. The applicant previously proposed a suspension wheel (patent application 1986-27) using this thrust ball bearing as a rotating wheel for buildings.
This is a composite thrust ball bearing created by combining the original No. 5692), and has a bearing force of 2.7 tons with the same diameter.

Therefore, all the drawbacks of the above-mentioned horizontal wheel suspension wheel that uses a radial ball bearing as the building rotation wheel can be solved by using this composite thrust ball bearing as the building rotation wheel. However, this suspension wheel with a horizontal wheel as a rotating wheel for buildings with a composite thrust ball bearing is a combination of thrust ball bearings as described above, and in addition, a suspension wheel with horizontal wheels has two layers, upper and lower. Therefore, the wheel sheaths for the traveling rails and intersection rails that house the wheels are of high volume.

Therefore, there is a tendency to increase the rail shape and weight. However, it is natural that the shape of the running rail etc. will be large for a heavy panel that exceeds 100 kg, and this is not considered a problem. Hanging wheels that use thrust ball bearings as rotating wheels for buildings have had a feeling of being inadequate.

The present invention is aimed at medium-sized panels in which movable panels are most commonly used, so it was developed through trial and error, apart from the rotating wheels for buildings using composite thrust ball bearings.

That is, efforts have been made to make the hanging wheel using the radial ball bearing shown in FIG. 4(b) as the rotating wheel for buildings more stable and to increase the load bearing capacity.

The first way to increase the bearing force is to increase the shape of the ball. However, this also increases the size of the hanging wheel and increases the cost. Therefore, there is a solution to increase the number of balls. However, with the conventional method, it has been impossible to insert a large number of balls into the ring hole.

That is, as shown in FIG. 6(a) of the drawings, first, one end of the outer ring part and the inner ring part are brought into contact with each other to create a wide space,
Insert the ball into this hole, return the outer ring part to a concentric circle with the inner ring part, and place the ball in the hole part.It is best to insert 7 balls as shown in the same figure (b). This is because balls that cannot fit into the wide space between the outer ring part and the inner ring part are excluded.

DISCLOSURE OF THE INVENTION In the building rotating wheel of the present invention, in the radial ball bearing,
The inner walls of the outer ring part and the inner ring part, which are the casing, are formed with deep concave grooves for ball holes provided with -striped notches,
In addition to preventing the ball from deviating, the inner ring part is divided into upper and lower halves.
It is possible to place the ball on the inside of the ball hole.

In addition, the suspension wheel of the movable panel is made by making the outer ring part of the rotating wheel for buildings larger than the inner ring part, and attaching it as a horizontal wheel to the hanging shaft in two layers, upper and lower.

BEST MODE FOR CARRYING OUT THE INVENTION In order to explain the present invention in more detail, examples will be described below with reference to the drawings.

A hanging wheel (hereinafter referred to as a hanging wheel) l of a movable panel according to the present invention is shown in FIG. 1, and a horizontal building rotary wheel 2 used therein is shown in FIGS. 2 and 5.

First, for the sake of convenience, the building rotating wheel 2 will be described.In the building rotating wheel 2, the balls 4, 4, which are steel balls in the radial ball bearing 3, are attached to the outer ring part 6, which is the casing of the bearing, as shown in the figure. In the opposing inner walls of the inner ring part 6, the ball holes 7 are arranged in a pie shape so as to be freely rotatable without coming into contact with each other, without coming into contact with each other. (Figure 6).

In the conventional radial ball bearing 3 shown in FIG.

As mentioned above, a wide space 8 is created between the outer ring part 5 and the inner ring part 6, seven balls 4.4 are placed there, and the outer ring part 5 is placed concentrically with the inner ring part 6. While returning the ball 4.
4... are arranged at equal intervals within the ball hole part 7.7, and the balls 4.4... are connected vertically with a retainer 9.9 to prevent them from deviating from the ball hole part 7.7. . The ball hole portion 7 of this conventional radial ball bearing 3 has a shallow notch in the concave groove of the curved surface, and when the ball hole portion 7 cannot withstand the weight load or is forced to travel quickly, the ball 4. 4...Despite the fixation by the retainer 9, there was a risk that the ball would deviate from the ball hole portion 7, but in the present invention, the curved surface of the ball hole portion 7 in the outer ring portion 5 and the inner ring portion 6 is fixed. The notch of the concave groove is deeper than that of the conventional one.

The balls 4, 4, . . . are rotatably fixed by the outer ring portion 5 and the inner ring portion 6 without using the retainer 9, without being easily dislodged.

Moreover, in this case, if both the outer ring part 5 and the inner ring part 6 are integral, it is impossible to insert the balls 4, 4, and so on into the ball hole part 7 as described above. In the present invention, as shown in FIG. 2, the inner ring part 6 is divided into upper and lower halves, and a casing is first formed by the downward ring part 10 and the outer ring part 5, and the balls 4,4... After arranging and filling the balls into the ball hole part 7 in one pie as described above, the upward ring part 11 is attached. The completed product is shown in Figure 5.

The above are the structure and effects of the building rotating wheel 2 according to the second aspect of the present invention.

Next, the suspension wheel l of the first aspect of the present invention will be described. As shown in FIGS. 1 and 2, the suspension wheel 1 is characterized in that the outer ring portion 5 of the building rotating ring 2 is formed larger than the inner ring portion 6. The hanging wheel 1 is a building rotary wheel 2.2 arranged on a hanging shaft 12 as horizontal wheels in two layers, upper and lower, and fixed rotatably.

As shown in FIG. 3, the hanging wheel 1
3, or a wheel sheath 14 of a general-shaped intersection rail (not shown) in which these rails are crossed at right angles in a cross shape.

The running rail 13 is a U-shaped horizontally elongated member with a downward frontage in its longitudinal section, and extends vertically inward from its side portion 15 at right angles, leaving a sliding groove 16 in the center in which the hanging shaft 12 slides. Triangular wheel bottoms 17° 17, which are inclined in the direction of the sliding groove in the longitudinal section, are protruded in two layers and alternately.

The wheel bottom 17 does not need to have such a triangular shape in longitudinal section and may have a simple horizontal shape. It is supported by the wheel bottom 17 having a triangular longitudinal section, or supported by the horizontal wheel bottom 17 at a part of the lower end surface portion 18 of the outer ring portion 5 . and wheel bottom 17.
17, the hanging shaft 12 is held vertically between the sliding grooves 16 by being supported vertically alternately, and the hanging wheel 1 maintains its balance. The movable panel 19 has a hanging wheel 10 and a hanging shaft 12 rotatably connected to the upper end surface 20 at two positions in the front and back or at the center, and the hanging wheel 1, l is rotatably connected in the wheel sheath 14 of the traveling rail 13. Installed and suspended. The movable panel 13 is moved by rotating the building rotary wheel 22 on the wheel bottom 17 as described above. The same applies to intersection rails that are approximately the same shape as the running rails.

In the rotating wheel 2 for buildings of the present invention, the radial ball bearing 3 has a bearing force of 350 kg, instead of the 24 kg described above. Also, the ball 4.4 via the retainer 9
It eliminates the inadequacy and complexity of fixing... and has a simple yet more solid structure.

Furthermore, by using the building rotating wheel 2.2, the suspension wheel 1 of the present invention can be used for a medium-weight panel (500 kg), which was the objective.
We have created a device that can sufficiently withstand the weight burden of approximately In other words, even one hanging wheel has a load of 700 kg. In addition, by making the outer ring portion 5 larger than the shape of the inner ring portion 6, that is, the outer ring portion 5 of the overcrowded radial ball bearing 3, it can be used as a reinforcing means to cope with friction with the wheel bottom 17. It has been effective.

Industrial Applicability The building rotating wheel 2 of the present invention is used not only for the hanging wheel 1, but also for rotating building turntables, rotating furniture, rotating walls, etc. The panel 19 can be used not only as a lightweight panel but also as a heavy panel with a large structure, and has extremely high industrial applicability.
