伸縮自在の誘導灯
Document Type and Number:
Japanese Patent JP6929900
Kind Code:
B2
Abstract:
To provide a lightweight, extremely portable guide lamp with sufficient visibility, having a simple structure and an extendable/retractable (foldable) light-emitting part.SOLUTION: A guide lamp 1 comprises: a light source part 2 that also serves as a grip part; and a light-emitting part 3 mounted on the light source part 2 such that light from the light source part 2 is communicated. The light-emitting part 3 is formed of a combination of a plurality of luminous tubes 3a, 3b having a long and hollow pyramidal shape. Due to a tapered structure of the luminous tubes 3a, 3b, the luminous tube 3a on an upper step side and the luminous tube 3b on a lower step side are connected so as to enable retraction by being mutually housed in a nested state, as well as extension. In an extended state, an extended structure of the light-emitting part 3 is held by a bottom of the upper step-side luminous tube 3a and a top of the lower step-side luminous tube 3b being connected by fitting, thereby allowing the light-emitting part 3 to be extendable/retractable in an axial direction.SELECTED DRAWING: Figure 1
