Abstract

A caster protection structure protects a caster provided at a base of a housing and used for transporting the housing in a movable manner, and includes a frame member that is provided at the base of the housing, serves as a part of a frame constituting the base of the housing, and extends in a predetermined direction. A longitudinal end position of the frame member is disposed in an outer region located beyond an outer lateral edge position of the caster.

First claim

What is claimed is:

1. A caster protection structure that protects a caster provided at a base of a housing and used for transporting the housing in a movable manner, the caster protection structure comprising:
a frame member that is provided at the base of the housing, serves as a part of a frame constituting the base of the housing, and extends in a predetermined direction, wherein the predetermined direction extends along at least one of outer side surfaces of the housing, and the predetermined direction comprising a diagonal direction,
wherein the frame member comprises a flat plate, a U-shaped cutout provided on an upper edge of the flat plate, and a bent portion provided on a lower edge of the flat plate,
wherein a longitudinal end position of the frame member is disposed in an outer region located beyond an outer lateral edge position of the caster.

2. The caster protection structure according to claim 1 ,
wherein the longitudinal end position of the frame member is disposed outward relative to the outer lateral edge position of the caster.

3. The caster protection structure according to claim 2 ,
wherein a longitudinal end of the frame member is disposed with a distance from the caster such that the longitudinal end is non-contactable with the caster when the caster rotates in any direction.

4. The caster protection structure according to claim 1 ,
wherein a longitudinal end of the frame member is disposed with a distance from the caster such that the longitudinal end is non-contactable with the caster when the caster rotates in any direction.

5. The caster protection structure according to claim 1 ,
wherein the frame member is provided along one edge of the base of the housing and is located at an outer side of the caster with respect to a direction intersecting a longitudinal direction of the frame member.

6. The caster protection structure according to claim 1 ,
wherein the caster includes a plurality of casters provided at corners of the base of the housing, and
wherein the base of the housing has a recess that is recessed downward in a region between the casters, and
wherein the U-shaped cutout surrounds the recess and the frame member extends in a longitudinal direction.

7. The caster protection structure according to claim 1 ,
wherein the caster includes a plurality of casters that are provided at opposite corners on one edge of the base of the housing and that are protected by opposite longitudinal ends of the frame member.

8. The caster protection structure according to claim 1 ,
wherein a lower end position of a longitudinal end of the frame member is disposed in a lower region below a center position of the caster.

9. The caster protection structure according to claim 8 ,
wherein the lower end position of the longitudinal end of the frame member is disposed downward relative to the center position of the caster.

10. A housing structure comprising:
a housing;
a caster that is provided at a base of a housing and that is used for transporting the housing in a movable manner; and
a caster protector that has a frame member extending in a predetermined direction and serving as a part of a frame constituting the base of the housing, wherein the predetermined direction extends along at least one of outer side surfaces of the housing, and the predetermined direction comprising a diagonal direction,
wherein the frame member comprises a flat plate, a U-shaped cutout provided on an upper edge of the flat plate, and a bent portion provided on a lower edge of the flat plate,
wherein a longitudinal end position of the frame member is disposed in an outer region located beyond an outer lateral edge position of the caster.

11. An article comprising:
the housing structure according to claim 10 ; and
various types of article components that are mounted in the housing structure.

12. A caster protection structure that is provided at a base of a housing and that protects a caster used for transporting the housing in a movable manner, the caster protection structure comprising:
frame means serving as a part of a frame constituting the base of the housing, the frame means being provided at the base of the housing and extending in a predetermined direction, wherein the predetermined direction extends along at least one of outer side surfaces of the housing, and the predetermined direction comprising a diagonal direction,
wherein the frame means comprises a flat plate, a U-shaped cutout provided on an upper edge of the flat plate, and a bent portion provided on a lower edge of the flat plate,
wherein a longitudinal end position of the frame means is disposed in an outer region located beyond an outer lateral edge position of the caster.
