## Title
Construction site fence panel foot boot

## Abstract

A construction site fence, or barrier foot plate base unit or foot cover attachment for separating the barrier from traffic and to guide traffic. The base unit attaches a traffic delineator thereon top of the base unit. Also, the base unit may include a pad that is tapered away from the construction site barrier panel foot, creating a gentle sloping ramp, including a combination of the sloping ramp and the delineator mount.

## Background
TECHNICAL FIELD
The invention relates to a construction site fence, or barrier, foot plate base unit or “boot”, and more specifically to a construction site fence panel foot cover attachment for separating the fence from traffic and to guide traffic so as to safely allow local traffic such as foot traffic and additionally to allow wheelchairs and scooters to travel safely over the foot.
BACKGROUND OF THE INVENTION
A construction site often requires a fence to help protect the site from materials being stolen or to keep traffic at a distance from the site or to prevent accidence such as people falling into an excavation.
Once a fence is installed around a construction site or along a construction site road frontage, there is a potential for traffic that is unfamiliar with the new barrier to come into contact with the fence or the fence panel feet. The typical construction site fence has panels that are roughly 7 feet tall by 10 feet long. The bottom corners of the panels are placed over a fence panel foot, where the foot allows additional panels to be attached and supports them vertically. The outermost part of the is “foot” is generally the furthest point away from the fence panel bottom and is subject to contact by close moving automobiles and or foot traffic, especially when the fence panels are erected on or near a sidewalk or walkway adjacent a street or a road.
To make pedestrians and drivers aware of the barrier it is beneficial to stand traffic delineators adjacent to the periphery of the fence so that traffic can easily see the temporary barrier. The most common approach currently in use is to place a traffic delineator, usually having a rubber base, next to or on top of the fence foot. Sitting on the fence foot allows the traffic delineator to often sit unlevel and the delineator can be easily knocked or moved out of position, or possibly stolen.
The present invention provides a construction site barrier foot plate base where the base can be readily attached to a traffic delineator without any major changes to a standard traffic delineator or any changes to the fence panel foot, and the base can be subsequently removed from the fence panel foot easily once the construction site fence is removed after site completion.
In a second embodiment of the present invention a construction site fence panel foot plate is covered by a gradually sloping base.
The gradually sloping base is readily attached to a fence panel foot plate as well without any changes to the fence panel foot plate and can also be subsequently removed from the fence panel foot when the construction site fence is removed after site completion.
In a third embodiment of the present invention it is sometimes an advantage to combine the sloping base unit as just mentioned with the ability to attach a traffic delineator as with the base unit as previously mentioned.
Accordingly, it is an object of the present invention to provide a construction site fence boot or base unit that easily attaches to a fence panel foot plate.
Another object of the present invention is to provide improved guidance for automobile traffic to help prevent contact with the fence panel by providing a secure attachment of a highly visible traffic delineator.
Yet another object of the present invention is to provide protection for pedestrian, wheelchair or scooter traffic from contacting the fence panel foot.
Still another object of the present invention is to provide for cleaner, neater look around the construction site fence.
A further object of the present invention is to provide a construction site fence panel foot base with added visibility.
The construction site fence foot plate base unit of the present invention has other objects and features of advantage which will become apparent from and are set forth in more detail in the accompanying drawings and following details.
DISCLOSURE OF THE INVENTION
The construction site fence panel foot base unit of the present invention is designed to cover the outward protruding fence foot plate, and comprises briefly, a base unit that includes a traffic delineator mount that longitudinally extends up from the base. The base unit attaches to the fence foot plate through an aperture, where the aperture slides over the fence panel foot plate. The unit includes a fastener which may be of various types. The fastener generally projects downward into the inside of the aperture so as to contact the fence panel foot plate when applied.
The base unit attaches various types of traffic delineators to the top of the base unit, usually by a bolt or other fastener running through the top portion of the base unit so that the delineator is attached to stand vertically from the top of the base unit. The delineator is generally a high visibility reflective component which are readily available through many industrial suppliers.
The base unit can also be attached in various other ways such as clamping or tying, such as with nylon ratchet straps or wiring in place.
In another embodiment of the present invention, the construction site fence panel foot base unit of the present invention is designed to cover the fence foot plate with a gradually sloping pad, and comprises briefly, a base unit having an aperture that slides over the fence foot plate. This base unit is generally made of plastic or rubber and tapers away from the top over the aperture to the edges of the unit. The base unit would reach out at least a few inches from the foot plate to provide a gentle slope or ramp area.
This style of “boot” provides a means for foot traffic, wheelchairs and scooters, to ride up over the boot eliminating potential tripping by pedestrians, and bumping by these smaller vehicle wheels, in the area of normal foot and pedestrian type traffic.
This aspect of the boot may include a high visibility reflective surface around it's perimeter.
As well, this type of boot can also be attached to the foot plate in various ways such as bolting, clamping or tying, such as with nylon ratchet straps or wiring in place.
In a third embodiment of the present invention, the two types of base units are combined so as to provide a more visible and further effective base unit that can be used in an area where all types of traffic can be expected. This base unit has a traffic delineator mount attached near the center of the pad of the base unit, where the delineator mount protrudes above the pad and includes a bolt hole through the delineator mount in the same manner to attach any commercially available traffic delineator.
As well, this type of boot can also be attached to the foot plate in various ways such as bolting, clamping or tying, such as with nylon ratchet straps or wiring in place.
Also, a “puzzle” screw head, or a non-standard key on a tamperproof set screw used on the base unit fastener(s) can further prevent stolen base units and traffic delineators.
