Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a caster mounting member that is interposed between a caster and a mounted body of the caster and can change a height and a pitch of mounting holes.
[0002]
[Prior art]
The mounting of the caster to the mounted body is predetermined by the position of the mounting hole drilled in the mounting base plate fixed on the pivot shaft of the caster.
However, when the pitch of the mounting holes of the mounted body is different from the pitch of the mounting holes of the casters, the casters cannot be mounted.
Further, when it is desired to set the height of the mounted body after the caster is attached to a predetermined height, if the height of the caster is low, the caster cannot be used.
In particular, when installation (grounding) means such as adjusters and stoppers are attached to the mounted body, and these are changed to casters, the pitch of the mounting holes is different, and the grounding surface of the mounted body is different. Since the height is different from the conventional one, it is necessary to manufacture casters according to those sizes, and there is a drawback that it cannot be easily changed to a general-purpose caster.

In short, the attachment of a mounting hole or the like on the top surface formed on the same surface of the first protrusion and the second protrusion. It suffices if a portion is formed, and similarly, a constraining portion such as the first and second constraining pieces may be formed on the bottom surface or the central base wall portion.
Moreover, in the said Example, although the case where the pitch of the attaching part (hole) of a mounting baseboard differs from the pitch of the attaching part (hole) of a caster attachment member was demonstrated to the example, it may be the same pitch. In that case, it can be used to increase the mounting height of the casters.
In other words, it goes without saying that various design changes can be made without departing from the scope of the present invention.
[0028]
【The invention's effect】
Since the present invention is configured as described above, when the pitch of the mounting holes and the mounting height are different between the mounted object and the caster, the caster mounting member is placed between the caster and the mounted object. By interposing, the caster can be attached to the attached object without producing a new caster, and the convenience is extremely high.
