Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to rollers for hanging exhibits, etc.
In particular, this invention relates to a roller for hanging exhibits, etc., which can freely change direction at the intersection of support rails arranged on a ceiling surface.

[Conventional technology and issues to be solved]

A roller for hanging an exhibit or the like has a pair of left and right rolling elements, which are supported and guided by support rails.

On the other hand, with the diversification of display methods, the support rails arranged on the ceiling are not only arranged in parallel, but may also be arranged in an intersecting manner.

In the case of rails with such intersections, conventional rollers have the disadvantage of not being able to change direction by 90 degrees at the intersections, making it impossible to meet the diverse needs of display methods.

Therefore, the object of this invention is to provide a roller for hanging exhibits, etc., which can change direction at the intersection.

[Means to solve the problem]

In order to solve the above problems, this invention has a boss part protruding from the lower surface of the board, and bearing pieces integral with the board are provided protrudingly at a predetermined interval at quarter positions on the side surface of the boss part. Two pairs of rolling elements are mounted between the boss part and each bearing piece by two pairs of shafts whose axes are perpendicular to each other, and the lower surface of each rolling element is made to protrude downward from the lower surface of the bearing piece and the boss part, and It has a configuration in which a hanging mounting shaft is provided at the center of the lower surface of the boss portion.

[Effect]

During normal running, a pair of left and right rolling elements are in charge of support and rotation, but at intersections, a pair of front and rear rolling elements, located 90 degrees apart, are in charge of support and rotation.

〔Example〕

FIG. 1 shows an embodiment of this invention, in which a substrate 1 is formed of metal, and a rectangular boss portion 2 is provided protruding from the center of the lower surface of the substrate 1. Bearing pieces 3 are protruded from each side surface of the boss portion 2 at regular intervals.

A rolling element 4 made of a roller bearing is interposed between each side surface of the boss portion 2 and each bearing piece 3, and a screw 5 inserted from the outside of the bearing piece 3 is passed through the rolling element 4. Insert the tip of the screw 5 into the boss part 2.
Fixed to. The axes of these screws 5 are
Orthogonal at the center of. Further, the lower surface of each rolling element 4 projects slightly downward from the lower end surfaces of the boss portion 2 and the bearing piece 3 (see FIGS. 1 and 2).

Further, a hanging mounting shaft 6 made of a threaded rod is fixed to the center of the lower surface of the boss portion 2.

A hanging tool 7 as shown in FIG. 3, for example, is attached to the mounting shaft 6, and an exhibit 10 or the like is hung from the hanging tool 7.

FIG. 4 shows the intersection of the support rails 8. The support rail 8 is channel-shaped, and the left and right rolling elements 4 are mounted on support portions 9 that protrude inward from the lower ends of both side walls, and are rolled thereon.

At the intersection, if a force is applied in a different 90 degree direction without changing the orientation of the substrate 1,
The pair of front and rear rolling elements 4 move onto the support portion 9 of the support rail 8 in that direction.

[Effect of idea]

As mentioned above, this invention has two pairs of rolling elements arranged on the front and rear and left and right sides supported by two pairs of shafts whose axes are perpendicular to each other, so that they can move not only in a straight line but also freely at intersections. , the direction can be changed freely by simply changing the direction of force application by 90 degrees. Therefore, according to this invention, exhibits, etc. can be moved freely through the intersection.
