Abstract
There is provided a collapsible barrel-shaped barricade which telescopes within itself for compact storage. Particularly, a solid and heavy base is provided for stability and a series of telescoping ring members are mounted thereon; the lowest ring being mounted to the base and upper rings being concentric with the lower ring. The concentric rings are arranged to interlock by placement of a tab from an inner ring into a horizontal slot on the inside of an outer ring. This interlock operates to hold the rings in an extended position when the barricade is in use.
Claims7
A barricade apparatus comprising:
- a base member having a first ring member affixed thereto;
- a plurality of upper ring members concentric with said first ring member whereon adjacent ring members overlap, thereby defining an inner and outer ring member;
- and
- means for interlocking adjacent ring members comprising,
- a plurality of tabs extending from the outer periphery of said inner ring members proximate the overlapped edges thereof, and
- a plurality of spaced horizontally oriented slots defined on the inner periphery of said outer ring members proximate the overlapping edges thereof, said slots being arranged to exhibit openings between said slots to allow vertical entry of said tab members therein, and wherein said slots are arranged to receive said tab members upon relative horizontal rotation of said adjacent ring members;
- whereby adjacent ring members are interlocked by first positioning said ring members such that said tab members are located within said openings between said slots and aligned with said slots, and then rotating said ring members to move said tab members into said slots.
