Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suspension vehicle having a moving wall that is suspended from a ceiling rail to move.

[0002]

[Prior art]

 The moving wall can be suspended from a suspension vehicle that runs on the ceiling rail and moved, and it can be arranged and fixed at a predetermined place to partition a large space. Here, there are various types of suspension vehicles, and a two-layer horizontal wheel type suspension vehicle is used for a relatively lightweight moving wall. Two horizontal wheels are provided at predetermined intervals on suspension bolts. It is rotatably attached and configured. On the other hand, a vertical wheel type suspension vehicle is used for the moving wall for heavy weight, and the suspension vehicle has a plurality of wheels pivotally supported on the side surface of a rectangular block forming a hexahedron.

The present invention is intended for the above-mentioned vertical wheel type suspension vehicle. However, since the suspension vehicle may suspend a moving wall of heavy weight, the suspension vehicle itself must have high strength. For this reason, the square block used is a cast product or a cut product of steel material, and is considerably heavy in weight. Therefore, it is inconvenient to handle and the cost is also high. On the other hand, a vertical wheel type suspension vehicle runs on the traveling surface of the ceiling rail, but a guide wheel is attached to the upper end of the suspension vehicle so that it does not come off from the traveling surface, and the suspension wheel slides in the guide groove It is fitted. However, since this guide wheel is made of metal, it produces a metallic noise when the suspension vehicle moves, which is annoying.

[0004]

[Problems to be solved by the present invention]

 As described above, the conventional suspension vehicle has the above problems. The problems to be solved by the present invention are these problems, and to provide a suspension vehicle that is light and durable without reducing strength and rigidity, and that does not generate metallic noise when traveling.

[0005]

[Means for Solving the Problems]

 The suspension vehicle according to the present invention comprises a rectangular block, which is the main body of the suspension vehicle, using a metal plate material. That is, the plate material is bent to form a box shape, adjacent side pieces are welded to each other, and ribs are provided inside the box shape body for reinforcement. A suspension bolt is attached to the center of the upper piece, and wheels are rotatably supported on the side pieces. Further, although a guide projects from the upper piece, the surface of the guide is made of resin. Here, the number of wheels attached to the side piece is not limited, and the attachment structure of the suspension bolts and the number of guides are also arbitrary, and are determined according to the specifications of the suspension vehicle. The usage of the suspension vehicle is the same as in the conventional method. The suspension vehicle is run on the traveling surface of the ceiling rail, the above suspension bolt is hung downward from the guide groove of the ceiling rail, and the moving wall is suspended from the suspension bolt. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 is an embodiment showing a suspension vehicle for a mobile wall according to the present invention. In the figure, 1 is a suspension vehicle main body, 2 is a wheel, 3 is a guide, and 4 is a suspension bolt. The basic form of the suspension vehicle is the same as the conventional one, and two wheels 2 and 2 are attached to each side surface of the suspension vehicle main body 1 so as to be rotatable. The guides 3, 3 ... Project from the upper surface of the suspension vehicle main body 1, and the suspension bolts 4 are attached to the suspension vehicle main body 1 and hang downward. Of course, a bearing 5 is interposed between the suspension bolt 4 and the upper surface 6 so that the suspension bolt 4 can rotate. In this embodiment, a dry bearing is used as the bearing 5.

By the way, the suspension vehicle main body 1 is not a conventional cast product or a steel cutting component, but is a box-shaped block body formed by bending a metal plate material, and has four side pieces 7, 7 on its four sides. , And the wheels 2, 2, ... Are attached to the side pieces 7, 7. FIG. 2 shows the bottom surface of the suspension vehicle. Both side edges of the side pieces 7, 7 formed by bending work contact each other, and the corners are welded. That is, the strength and rigidity of the box-shaped block body can be greatly improved by welding the side pieces 7, 7 ...

Further, in order to increase the strength of the suspension vehicle main body 1, ribs 8, 8 ... Are welded inside the side pieces 7, 7. The ribs 8, 8, ... Shown in FIG. 2 are arranged so as to be slanted across the adjacent side pieces 7, 7, but the arrangement of the ribs 8, 8, ... Is arbitrary. For example, a cross-shaped rib parallel to each side piece 7, 7 ... May be used.

The suspension vehicle main body 1 shown in FIGS. 1 and 2 is a box-shaped block body formed by bending a protruding piece of a cross-shaped plate material, and thereafter, each side piece 7, 7, ... Although it is welded and fixed, some distortion occurs due to welding. Of course, the shaft hole for attaching the wheel may be machined after welding, but in order to reduce the welded portion as much as possible, the box-shaped block body can be molded by drawing.

As described above, the guides 3, 3 ... Stand upright on the upper surface of the suspension vehicle main body 1 configured as a box-shaped block body, but the guide 3 has the metal shaft core 9 as the upper piece 10. It is fixed to. A hole is penetrated through a predetermined portion of the upper piece 10, and a leg 11 of the shaft core 9 is fitted into the hole and caulked. A resin guide wheel 12 is fitted on the shaft core 9, and the guide wheel 12 can rotate about the shaft core 9. A flange 13 is formed on the upper end of the shaft core 9, so that the guide wheel 12 does not come off from the shaft core 9. Here, the guide 3 may be fixed to the shaft core 9 without rotating. As described above, the suspension vehicle according to the present invention is one in which the suspension vehicle main body is made of a metal plate material, and the following effects can be obtained.

[0011]

[Effect of device]

 Since the suspension vehicle of the present invention is made of a metal plate material for the suspension vehicle main body, it is easier to fabricate and the manufacturing cost is lower than when cutting conventional cast products or steel materials. Of course, it is lightweight and convenient to handle. Also, although the suspension car body is a box-shaped block body made of a plate material, the ribs are provided inside the suspension car body, so that the strength and rigidity are high, and there is no deterioration compared to conventional suspension car bodies. On the other hand, since at least the outer circumference of the guide standing on the upper surface of the suspension car body is made of resin, no metallic noise is produced when traveling on the ceiling rail, and the moving wall can be moved quietly.
