Fall prevention device and image forming apparatus
First Claim
1. A fall prevention device configured to prevent an installation object from falling over by supporting a leg member including a base portion and a shaft portion when an installation surface oscillates, the base portion being in contact with the installation surface, the shaft portion connecting the base portion and a bottom portion of the installation object to each other and having a diameter that is smaller than a diameter of the base portion, the fall prevention device comprising:
- a support member provided on the installation surface;
a first restricting member provided on the support member and comprising a first restricting body portion disposed above an upper surface of the base portion, the first restricting body portion comprising a first shaft-penetrating portion through which the shaft portion penetrates;
a second restricting member disposed above the first restricting member, and comprising a second shaft-penetrating portion through which the shaft portion penetrates; and
an adjustable member attached to the shaft portion,wherein a top surface of the first restricting member does not contact to a bottom surface of the second restricting member at a position near the first shaft-penetrating porting of the first restricting member and the second shaft-penetrating portion of the second restricting member, andwherein a gap disposed between the second shaft-penetrating portion and the adjustable member along an extending direction of the installation surface is smaller than a gap disposed between the first shaft-penetrating portion and the shaft portion.

Abstract
Provided is a fall prevention device that prevents an installation object from falling over by supporting a leg member including a base portion and a shaft portion when an installation surface oscillates. The fall prevention device includes a support portion supported by the installation surface, a first restricting portion supported by the support portion, correspondingly disposed above an upper surface of a base portion, and having a first shaft-penetrating portion through which a shaft portion penetrates, and a second restricting portion disposed above the first restricting portion at a bottom-portion-side end portion of the shaft portion. The second restricting portion has a second shaft-penetrating portion through which the shaft portion penetrates. A gap that is smaller than a gap between the first shaft-penetrating portion and the shaft portion is formed between the second shaft-penetrating portion and the end portion of the shaft portion.

8. A fall prevention device configured to prevent an installation object from falling over by supporting a leg member including a base portion and a shaft portion when an installation surface oscillates, the base portion being in contact with the installation surface, the shaft portion connecting the base portion and a bottom portion of the installation object to each other and having a diameter that is smaller than a diameter of the base portion, the fall prevention device comprising:
-
a support member provided on the installation surface; a first restricting member provided on the support member and comprising a first restricting body portion disposed above an upper surface of the base portion, the first restricting body portion comprising a first shaft-penetrating portion through which the shaft portion penetrates, a width of the first shaft-penetrating portion being smaller than a width of the base portion; a second restricting member disposed above the first restricting member, and comprising a second shaft-penetrating portion through which the shaft portion penetrates; and an adjustable member attached to the shaft portion, wherein a top surface of the first restricting member does not contact to a bottom surface of the second restricting member at a position near the first shaft-penetrating porting of the first restricting member and the second shaft-penetrating portion of the second restricting member, and a gap disposed between the second shaft-penetrating portion and the adjustable member along an extending direction of the installation surface is smaller than a gap disposed between the first shaft-penetrating portion and the shaft portion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 16, 18)
