Housing structure and object using the same
A housing structure for wheeled equipment includes a housing with top, bottom, and side portions. Multiple wheeled supports are mounted on the bottom portion to enable movement of the housing. A grip is positioned on the top portion or upper side portion of the housing for manual grasping during tilting operations. A footstep is located at the bottom portion between two rear wheeled supports on the side opposite the advancing direction. The footstep is positioned forward of the center axis of the rear wheels' diameters relative to the housing's advancing direction. This arrangement allows an operator to step on the footstep while gripping the upper portion to tilt the housing backward, with the rear wheel contact points serving as pivot points during the tilting operation.
1 . A housing structure comprising:
a housing including a top portion and a bottom portion with at least a side portion surrounded by a plane;
a plurality of movable supporters that are provided on the bottom portion of the housing and support the housing via a plurality of wheels capable of moving the housing, two wheels of the plurality of wheels being positioned on a side of the housing opposite to a predetermined advancing direction of the housing, being separated from each other in a width direction intersecting the predetermined advancing direction, and providing pivot points when the housing is tilted;
a grip provided on the top portion or at an upper half portion of the side portion of the housing and being capable of being gripped with a hand of an operator when the housing is tilted; and
a footstep that is provided at the bottom portion of the housing between two movable supporters located on the side opposite to the predetermined advancing direction of the housing and on which a foot of the operator is able to be hooked when the housing is tilted,
wherein the footstep is arranged on an advancing direction side of the housing with respect to center positions of diameters of wheels of the two movable supporters as a boundary and no portion of the footstep is arranged rearward of the center positions of diameters of wheels of the two movable supporters relative to the predetermined advancing direction.
2 . The housing structure according to claim 1 ,

3 . The housing structure according to claim 2 ,
wherein, in the footstep, a member constituting the footstep portion is fixed to a bottom frame constituting the bottom portion of the housing.
4 . The housing structure according to claim 1 ,
wherein the footstep is covered with a detachable covering when not in use, and the covering is removed when in use.
5 . The housing structure according to claim 4 ,
wherein the footstep also serves as an attachment portion to which an overturning-prevention support part is attached.
6 . The housing structure according to claim 1 ,
wherein the footstep is arranged on the advancing direction side of the housing so as to include the center positions of the diameters of the wheels of the two movable supporters.
7 . The housing structure according to claim 6 ,
wherein the footstep is provided between the center positions of the diameters of the wheels of the two movable supporters and the bottom portion of the housing.
8 . The housing structure according to claim 1 ,
wherein the grip is provided so as not to protrude outward from the side portion of the housing.
9 . The housing structure according to claim 8 ,
wherein the grip also serves as a supporter that is provided on the top portion of the housing and supports a reading unit that reads a target to be read placed on the top portion of the housing.
