Description

[Detailed description of the invention] This invention is a mobile underfloor storage, more specifically, a mobile under-floor storage that allows the storage box to be moved along the guide rail by running casters installed in the storage box on the guide rail. Regarding under-floor storage.

In conventional mobile underfloor storage of this kind, guide rails having an L-shaped cross section, and L-shaped guide rails having an L-shaped edge having a surface perpendicular to the rail surface have been known. However, the L-shaped guide rails have a drawback that it is difficult to set the distance between the guide rails during installation. On the other hand, in the case of an L-shaped guide rail having a right-angled surface, since the right-angled surface is formed on the edge of the rail surface, the side surface of the caster will be bent due to deflection in a direction approximately perpendicular to the direction of movement that occurs when moving the storage box. This has the disadvantage that when it comes into contact with the caster, it acts as a resistance against the caster and brakes the movement of the storage box.

This idea forms an inclined surface that protrudes upward at an angle of 135° to 155° with respect to the rail surface along the edge of the rail surface, and between the guide rails, the outer side of the caster running on one guide rail is The above-mentioned drawbacks are eliminated by providing a movable underfloor storage facility characterized in that the casters running on the other guide rail are at a spacing that spans the slope when it comes into contact with a side surface that stands up from the other edge of the rail surface. The purpose is to

The following description will be made with reference to FIG. 1 showing a plan view of an embodiment of this invention, FIG. 2 showing a side sectional view, and FIGS. 3 and 4 showing a partially enlarged view of FIG. 2. 1
is the floor surface in a residence such as a kitchen or a hallway. 2
is an opening in the floor between the 3 joists and the 4 main drawers. Reference numeral 5 designates a guide rail made of galvanized steel, including a rail surface 6, a side surface 7 standing upright on the large pull side along the edge of the rail surface 6, and a side surface 7 located above the opening 2 side along the opposite edge of the rail surface 6. It has an inclined surface 8 formed to protrude toward. The inclined surface may be a flat surface or a slightly curved surface. The angle θ between the inclined surface 8 and the surface of the rail 6 is, as shown in FIG. 4, in the range of 130° to 155°, preferably approximately 150°. The inclined surface 8 and the rail surface 6 may be joined through a curved surface or directly, and the side surface 7 is connected to the rail surface 6.
It does not have to be formed over the entire length. The guide rail 5 is fixed to the upper part of each of the large drawers 4, 4 facing the opening 2, with the rail surface 6 facing upward, in two parallel strips, using screws or the like. 9 is a storage box made of FRP, high-density polyethylene, or polyethylene, 10 is a frame, 11 is a bearing, and 12 is a caster. The storage box 9 is removably supported around the upper edge by a substantially rectangular frame 10, and casters 12 are fixed to the sides of the storage box 9 through bearings 11 near the four corners of the frame 10. The storage box 9 may be provided with a lid, and a cushioning material may be fixed to the side of the caster 12.

Between the two parallel guide rails 5, 5, when the outside of the caster 12 running on one guide rail contacts the side surface 7, at least one of the casters 12 running on the other guide rail touches the slope 8. Such an interval is necessary. In other words, caster 1 running on the other guide rail
It is necessary that the interval is such that a part of the surface of the caster 2 runs on the slope 8 or the entire surface of the caster 12 runs on the slope 8.

Therefore, when moving the storage box 9, the casters 12 are moved along the guide rails 5.
During this movement, the caster 12 swings in the width direction of the rail surface in a direction substantially perpendicular to the traveling direction. However, in this invention, the distance between the guide rails 5 and 5 is such that when the outside of one caster comes into contact with the side surface 7, the caster on the opposite side of the storage box will touch the slope 8. When the other caster 12 swings outward, that is, to the side, the inside of the other caster 12 touches the inclined surface, which prevents it from swinging further in the same direction, and since the inclined surface has an inclination of 135° to 155°, the movement of the caster 12 is prevented. By applying the brakes, it is possible to avoid jerky operation, and the storage box moves straight forward smoothly. If θ is smaller than 135°, the inclined surface 8 acts as a brake on the caster in contact with it, and if it is larger than 155°, it is difficult to correct the swing of the caster to one side.

Furthermore, since the caster 12 is fixed to the side of the storage box 9, the height of the guide rail can be saved and the storage box can be easily attached and removed. Therefore, this invention provides a mobile underfloor storage that is easy to install and moves smoothly in a straight line.
