BACKGROUND OF THE INVENTION1. Field of the Invention
This invention generally relates to security delimiters, and more particularly, to portable extensible and collapsible barriers or security gates that can be used both outdoors and indoors to barricade or delineate a secure area.
2. Description of Related Art
Conventional barricades are well known and have been in use for a number of years. Regrettably, most conventional barricades suffer from obvious disadvantages in that they are not standalone, portable, and extensible, cannot be deployed with ease, and cannot be concatenated to increase a span or coverage of a delineated secure area. In addition, conventional barricades are not adjustably expansible to a desired span to adjustably delineate a specific desired secure area.
Accordingly, in light of the current state of the art and the drawbacks to current conventional barricades mentioned above, a need exists for a standalone security delimiter that would be portable and extensible, would expand or collapse to a desired span, would be interconnected, and easily deployed to quickly secure a desired area.

The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed and or utilized.
The present invention provides a security delimiter that is comprised of a standalone, portable, and extensible lattice structure that includes a plurality of towers that are adjustably linked, and able to adjustably expand to a desired linear span to secure an area.
As further illustrated, the multiplicity of portable towers 102, 104, 130 and 132 are comprised of a series of towers, with a tower of the series of towers movably coupled with a next, subsequent adjacent tower of the series of towers. The series of towers are comprised of a first set of towers 102 and second set of towers 104, with a tower of the first set of towers 102 juxtaposed and movably coupled with a next, subsequent adjacent tower of the second set of towers 104. One of the first set of towers 102 and the second set of towers 104 includes wheels 120, and at least one tower 130 and 132 also includes a wheel lock 101.
The multiplicity of portable towers 102, 104, 130 and 132 are comprised of a top piece, a first lateral piece coupled with a first distal end of the top piece, a second lateral piece coupled with a second distal end of the top piece, a first leg coupled with the first lateral piece, and a second leg coupled with the second lateral piece. More specifically, the multiplicity of towers 102, 104, 130, and 132 of the security delimiter 100 are comprised of a top semi-circular piece 106 that may optionally include a solar panel 150 for generation of electricity, which may be used to light a sign such as a “STOP” or “NO ENTRY” light signals. The towers 102, 104, 130, and 132 further include a first lateral piece 110 coupled with one of a first distal end and a second distal end of the top piece 106, and a second lateral piece 118 coupled with another of the second distal end and the first distal end of the top piece 106.

The first lateral piece 110 and the second lateral piece 118 are comprised of an elongated, vertically oriented elements that are positioned transverse the reciprocating span axis 190, with a top distal ends thereof coupled with the top piece 106 and a bottom distal ends thereof coupled with one of the first leg and the second leg 112. As further illustrated in
As further illustrated, the linking structure 205 is comprised of a series of crossing, pivoted levers joined together. A first set of levers 136 having a first connection point pivotally coupled with a wheel axel 122, and a second set of levers 137 having second connection point pivotally coupled with a bottom axel 124. The first set of levers 136 and the second set of levers 137 are pivotally interconnected at pivot connection points 202, including pivotal connections with the top axel 160. As illustrated, the first set of levers 136 and the second set of levers 137 are pivotally interconnected via horizontally oriented pivot interconnections 202, forming the linking structure, configured somewhat similar to a typical lazy tong structure. Both of the “return” levers 134 for the first tower 130 and the “return” lever 137A for the second tower 132 are shorter in length than the remaining levers, otherwise, they are similar with similar connections.
As further illustrated, the first set of levers 136 have a substantially mid-connection point 202 pivotally coupled with an oppositely oriented, laterally adjacent second set of levers 137, and with a tower of the multiplicity of towers via the top-axel 160, forming a lazy tong linking structure. The opposite distal ends of the top-axel 160 are inserted within the set of slits 138, which are positioned at the inner bottom distal ends of the first lateral section 110 and the second lateral section 118, oriented transverse the reciprocating span axis 190 of the security delimiter 100, enabling a vertical movement, transverse the reciprocating span axis 190 of the lattice structure.

As illustrated in
In general, the height 2006 of the security delimiter 2000 is made longer than the height of the security delimiters mentioned above. This means that both the frame and the link structures are longer to reach the desired height. Given the greater height 2006, the security delimiter 2000 is provided with greater width span 2008, greater number of levers 2034 connected for each tower, a tower base 2020, and wheels 120 positioned at the very distal ends 2020 (at the exterior side) of the towers for increased stability (prevents security delimiter 2000 from being toppled). The security delimiter 2000 further provides lifts 2024, which when used, enable the wheels 120 of the entire unit to be raised off the ground, making the security delimiter 2000 stationary, when needed.
