Abstract
A support post and safety fence assembly in which the post has a telescoping inner and outer tube and is supported on a threaded internal shaft coupled to a floor engaging end and ceiling engaging end preferably formed with claws that have a number of sharp penetrating points for firm engagement with a support surface. In one embodiment, a gravity lock assembly is provided for fixing the relative position of the inner and outer tubes. Dynamic adjustability of the support post is provided by internal compression springs.
Claims7
A support post for a safety fence assembly, the post having
- a floor engaging end,
- a shaft coupled at one end to said floor engaging end and having a free end which is threaded along at least a portion of its length,
- a first longitudinally extending tube having an internal nut for threaded engagement with said shaft,
- a second longitudinally extending tube adapted for sliding telescoping engagement with said first tube;
- and
- a ceiling engaging end coupled to said second tube, the first tube having a series of longitudinally spaced apertures for receiving a lock to fix the relative position of said first and second telescoping tubes, said first tube defining an outer tube and said second tube defining an inner tube,
- the inner tube having a pendulum lock pivoted to an operatively lower end of a pendulum stem slidingly received in the inner tube, the pendulum lock being adapted to locate in a selected one of said apertures in the outer tube to fix the relative position of the telescoping inner and outer tubes.
In combination, a plurality of support posts and a plurality of fence panels forming a safety fence assembly, each post having
- a floor engaging end,
- a shaft fixed at one end to said floor engaging end and having a free end which is threaded along at least a portion of its length,
- a first longitudinally extending tube having an internal nut for threaded engagement with said shaft,
- a second longitudinally extending tube adapted for sliding telescoping engagement with said first tube;
- and
- a ceiling engaging end coupled to said second tube;
- and
- each fence panel having a rectangular frame including a pair of spaced oppositely disposed upright members and a fence lock rotatably coupled at one end to at least one of said upright members, the fence lock having a free end which is bent so that when the free end is rotated away from the upright member, the free end is adapted to capture a support post between the fence lock and the associated fence panel by sliding the fence panel.
