COLLAPSIBLE LIGHT

摘要

A collapsible lighting device has a main body surrounded by a collar whose position is adjustable along the longitudinal axis of the main body. Pivotally connected or hinged legs are attached to the collar and to the main body with struts. When the collar is on one position, the legs deploy outward from the main body to the extent permitted by the struts, thereby allowing the legs to support the collapsible lighting device upright. A lamp head is attached to a member which telescope from the main body. When deployed, the lamp head can be switched on to provide illumination. When the collar is another position, the legs are drawn in toward the main body to form a cylindrical shape. The lam head can be positioned so that when the telescoping member is retracted into the main body, the collar surrounds the exterior of the lamp head, thus protecting the lamp head for transport. The overall cylindrical shape of the lighting device in the collapsed position facilitates transport, for example using a strap to carry the device on one's back.

主权项

1. A collapsible lighting device comprising:
a main body having a cylindrical configuration; a telescoping member adjustable within said main body; a lamp head connected to said telescoping member by a pivoting connection; an electrical connection between said lamp head and a power source; a collar surrounding said main body, said collar being adjustable to a first collar position relative to said main body when said portable lighting device is in a deployed position, and to a second collar position relative to said main body when said collapsible lighting device is in a collapsed position; and at least one leg pivotally connected to said collar and to said main body to support said main body in a generally vertical orientation when said collar is in said first collar position; wherein said telescoping member has a longitudinal axis along which said telescoping member is adjustable in length, said pivoting connection between said lamp head and said telescoping member comprises an offset hinge having an axis of rotation that is laterally offset from the longitudinal axis of said telescoping member.
