Stanchion or Post with Low Profile Circular Base
Abstract
A post including a cylindrical weighted base with an end cap
having a threaded hole in the center. A low profile circular base
having a center threaded portion is attached to the post using the
threaded hole in the post end cap. The design is ideal for use in
spaces where handicapped access is required. The low profile
circular base allows for safe traverse from wheelchairs. The low
profile post may be easily disassembled without the use of tools by
simply unscrewing the weighted post tube from the circular
base.

FIELD OF THE INVENTION
[0006] The present invention relates to stanchions or posts used in
both indoor and outdoor environments. More specifically, the
present invention is a stanchion including an internal weighted
base with the bottom end having a center threaded hole for
attachment to a circular base. The circular base would be
approximately 1/4 inch thick so that wheelchairs could easily ride
over it if needed.
BACKGROUND OF THE INVENTION
[0007] A stanchion is a sturdy upright post that provides support
for various applications such as controlling the flow of people or
construction related applications such as road signs. Typically
these posts are of hollow tube construction so that the tops of the
posts can be fitted with cassette belts, lanyards, ropes, chains or
signs depending on the specific intended use of the post. Most
indoor posts are mounted on a weighted base that typically consists
of a disc shape weighing approximately fifteen pounds. Most outdoor
posts are mounted on a tripod stand and can include a threaded
center rod to anchor the post into the ground.
[0008] There are several problems with a post that is mounted on
either a weighted base or a tripod stand. First, the weighted base
or tripod stand is often a large diameter size such as between two
and four feet, and therefore posts having weighted bases or stands
take up a lot of space when they are in storage. Second, posts
having either weighted bases or tripod stands tend to degrade
quickly in their appearance by getting dinged or scratched from
close contact with other posts while in storage in a closet, shelf
or truck bed. Finally, since the weighted base or tripod stands are
typically attached to the post itself using small threaded
fasteners such as screws or locking pins, it is common for these
threaded fasteners to become easily lost or damaged over time by
dirt, debris or rust from environmental exposure at road
construction sites.
[0009] U.S. Pat. No. 9,863,165B1 issued to Hongthong solves the
aforementioned problems by providing a stanchion having an internal
weighted base with spring loaded retractable legs that can be used
in both indoor and outdoor applications. Hongthong's post allows
for efficient storage and allows the same number of posts to be
stored in a closet or shelf instead of a larger storage room. The
post is quick to setup without the need for tools. To deploy, a
locking tab is rotated to allow the legs to drop out the bottom
through slots at the base of the post.
[0010] Although the prior art post of Hongthong solves the
aforementioned problems inherent with prior art posts, the post
does not work well in situations where there is required to provide
access for handicapped people using wheelchairs. In wheelchair
accessible areas, the wheelchair cannot ride over the retractable
legs without risking tipping over of the wheelchair. To address
this deficiency, the present invention uses a low profile circular
base that screws into a threaded hole located at the bottom end of
the post. An internal cylindrical weight makes up for the low
profile base to provide stability.
SUMMARY OF THE INVENTION
[0011] It is a primary object of the present invention to provide a
post that has an internally contained weighted base with the bottom
end having a threaded hole at the center.
[0012] A second object of the present invention to provide a low
profile circular base with a center threaded portion to screw into
the threaded hole at the bottom end of the weighted post.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a perspective view of the low profile circular
base stanchion.
[0014] FIG. 2 is a top view of the low profile circular base
stanchion.
[0015] FIG. 3 is a cross sectional view of the low profile circular
base stanchion taken along line A-A of FIG. 2.
DETAILED DESCRIPTION OF THE INVENTION
[0016] FIG. 1 shows the low profile circular base stanchion 200. A
hollow tube 202 contains a cylindrical weight 203 which rests on
top of a bottom end 204. The bottom end has a center threaded hole
for attachment to a low profile circular base 205.
[0017] Referring next to FIG. 2, the top view of the low profile
circular base stanchion 200 is shown. The circular base 205 must be
of sufficient diameter to provide stability for the stanchion. A
recommended size of the circular base 205 would be 20 to 30 inches
in diameter. The center post tube 202 is typically between 4 to 6
inches in diameter.
[0018] Referring finally to FIG. 3, a cross sectional view of the
low profile circular base stanchion 200 is shown. The cylindrical
internal weight 203 would typically be made of steel or aluminum
and would have a typical length of 12 inches. The low profile
circular base 205 should have a maximum thickness of approximately
1/4 inch. The threaded hole size needs to be large enough to easily
attach the post to the low profile circular base and a recommended
size range would be 1/4 to 3/4 inch diameter with a coarse pitch
thread of 12 to 18 threads per inch.
