## Title
Stackable, modular barricade

## Abstract

A modular, movable, barricade which has, along its bottom edge, a one or more of supporting feet configured to allow stacking during storage and/or transport. Individual, similar barricade modules may be easily assembled into customized configurations for use by complementary attachment means along the side edges. After use, an assembled customized configuration may be easily disassembled into individual barricade modules by detaching the attachment means. The modules may then be stacked for storage and/or transport until further use.

This application claims the benefit of United States Provisional application Ser. No. 62/126,149, filed Feb. 27, 2015, and whose contents are incorporated by reference herein in their entirety.


FIELD OF THE INVENTION
Embodiments of the present invention include movable barricades, and more specifically, modular, movable barricades.
BACKGROUND OF THE INVENTION
A common method of creating barricaded spaces or crowd control is by the use of movable barricades.
Movable barricades are used in a wide variety of applications. Some examples are:
Parks
Parking
Restaurant
Street Fairs
Carnivals
Construction Sites
Police Activities
Ski Resorts
Private Pools
Sports
Universities
Military
Concerts
Airports
Stadiums
Golf
Parties
Camps
Rental Companies
Malls
Casinos
Convention Centers
Theaters
Zoos; and
Other Events.
The barricades are often modular units, which can be configured as needed for each use. Typically, multiple barrier units are set up as needed and then moved away and stored until the next use.
In the prior art, such barricades are usually made of metal. However, metal barricades are heavy, hard to maneuver and set up, tend to rust/corrode, and take up a lot of space to store between uses.
Thus, it is desired to have a method and system for creating barricaded spaces or crowd control which overcome these prior art limitations.

DESCRIPTION OF THE INVENTION
Embodiments of this invention comprise a modular movable barricade 1. (In this Specification, the embodiment is referred to interchangeably as a “barricade”, a “module”, or a “unit”.) For one embodiment, typical dimensions of the barricade 1 may be approximately 78 inches long, 39.5 inches high, and 2 inches deep (excluding the unit's “feet”); however, for specific applications, the barricade unit 1 may have, and would preferably have, dimensions chosen for that specific application.
Preferably, the barricade 1 is made of plastic. Plastic allows for a more economical and lighter unit compared to a metal construction. Also, the plastic is preferably recyclable, such as polypropylene. This choice of plastic addresses ecological and environmental concerns about using the barricade modules 1.
Each barricade module 1 has built-in connecting mechanism components 2, 3 for connecting to other identical or very similar barricade modules 1. Along one side of the module 1 is a grabbing mechanism 2; on the opposite side of the module is a receiving mechanism 3. The grabbing mechanism 2 of one module 1 is connectable to the receiving mechanism 3 of an adjacent module 1, preferably by “snapping” it into place. Alternatively, the connecting mechanism components 2, 3 may be held together by a suitably shaped pin inserted into and between them. This connection method allows for rapidly, and flexibly creating barricaded areas to meet the users' needs.
Along the underside of the barricade module 1 are “feet” 4, 5 which extend generally perpendicularly from the body of the module 1. Each foot 4, 5 angles away and downward from the underside of the barricade 1. The feet 4, 5 have a cross section in which the top surface is complementary (opposite) to the bottom surface. For example, the feet 4, 5 may be flat, have an arc-shaped cross section, or a trapezoidal-shaped cross section.
These feet 4, 5 support and maintain the module 1 in a vertical position during use. These feet 4, 5 are integral to the module and are also preferably made of plastic. Preferably, the feet 4, 5 are created along with the creation of the module 1, for example, by a molding process. Thus, the entire module 1 has a single piece construction for additional strength.
The feet 4, 5 are arranged in pairs. In each pair, one foot 4 extends outward from the body of the module 1 in one direction and the other foot 5 extends outward from the body of the module 1 in the opposite direction.
By way of example only, for one embodiment, the feet 4, 5 are preferably tapered with a maximum width (at the connection to the body of the module 1) of approximately 4 inches. The span from the tip of one foot 4 to the tip of the other foot 5 in the pair is approximately 20 inches; however, for specific applications, the barricade unit 1 may have, and would preferably have, feet 4, 5 with dimension chosen for that specific application.
The feet 4, 5 in each pair are preferably placed in a staggered arrangement. Further, the feet 4, 5 in each pair are preferably shaped so that the “front” foot 4b of a second module 1b can be placed under the corresponding “front” foot 4a of a first module 1a while at the same time, the “back” foot 5b of that second module 1b can be placed over the corresponding “back” foot 5a of that first module 1a (see FIGS. 17 and 18). Thus, the combination of stagger and shape allow multiple modules 1a, 1b to be stacked closely together during transport and storage.
Preferably, there are two sets of feet 4, 5 for each module 1, located closer to the ends of the module 1 than to each other. However, other numbers and arrangement of pairs of feet 4, 5 may be chosen for specific applications.
In another embodiment of this invention, the barricades 1 may be customized, during or after manufacture, with one or more colors and/or with information desired by the user. Also, signs may be attached to the barricades 1 in varying colors and/or with such information. Examples of such information include without limitation:
name
trademark
logo
website
sponsors
supporters; and
advertisers.
Individual modules 1 may be mixed and matched with different colors and such information.
In use, barrier modules 1 as needed are taken from storage and connected together in a desired arrangement. During use, the modules 1 may be easily separated and reconnected in another desired arrangement. When the need for the barricade arrangement is complete, the modules 1 are separated, stacked together, and stored compactly.
Stacking is accomplished by placing the “front” foot 4b of a second module 1b under the corresponding “front” foot 4a of a first module 1a while at the same time, placing the “back” foot 5b of that second module 1b over the corresponding “back” foot 5a of that first module 1a and pushing the two modules 1a, 1b together (see FIG. 17). Stacking continues by placing the “front” foot 4c of a third module 1c under the corresponding “front” foot 4b of that second module 1b while at the same time, placing the “back” foot 5c of that third module 1c over the corresponding “back” foot 5b of that second module 1b and pushing that third module 1c next to the first and second modules 1a, 1b. This process is repeated until all desired modules 1 are stacked and closely positioned together. Thus, combination of stagger and shape of the feet allows multiple modules 1 to be stacked closely together during transport and storage.
Thus, this invention overcomes the limitations of the prior art barricades with a functionally designed modular barricade 1 which is durable, lightweight, strong, versatile, easy to store, easy to handle, does not rust, pleasing in appearance, customizable, and ecologically/environmentally sensitive. The modules 1 preferably have one-piece construction allowing for stronger units 1 with no weak points. Further, the modules 1 are quick interlocking units. Finally, the modules 1 are stackable for compact storage.
Therefore, although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
