DETAILED DESCRIPTION

(9) Referring to the drawings, some of the reference numerals are used to designate the same or corresponding parts through several of the embodiments and figures shown and described. Corresponding parts are denoted in different embodiments with the addition of lowercase letters. Variations of corresponding parts in form or function that are depicted in the figures are described. It will be understood that variations in the embodiments can generally be interchanged without deviating from the invention.

(10) Bollard collars equipped with barrier attachment elements, that fit over and/or around bollards, offer a cost-effective retrofit to existing bollards that lack attachment elements and thus allow attachment of barriers such as walls, nets, gates, etc., without having to replace the original bollards.

(11) FIG. 1 depicts a collar assembly for retrofitting a barrier 10 to one or more bollards 12. As shown, bollards 12 are short, thick posts having a vertical length and a width. Bollards 12 are typically cylindrical as shown in the figure but other cross-sectional dimensions are possible, including: round, rectangular, triangular, flower-shaped, tri-oval, hexagon, conical, or any other shape imaginable. Thus, with respect to the bollards disclosed herein, the present invention is not limited to any particular shape or dimensions. Bollards 12 themselves typically do not have any means to attach or secure barriers 10 short of tying a rope around the circumference of the bollard. FIG. 1 shows a barrier 10 retrofitted to the bollard 12 by mounting them to a plurality of collars 14. Each collar 14 is adapted to fit around each bollard 12.

(12) As best understood by comparing FIGS. 1, 2, and 2A, each collar 14 comprising two or more openings 16. The openings 16 are configured to receive a securing element 18 or a barrier mounting device 20. The securing elements 18 are configured to affix the collar 14 to the bollards 12. The number and configuration of securing elements 18 may vary by the specific embodiment, but in general enough securing elements 18 are used to sufficiently secure the collar 14 to the bollard 12.

(13) At least one barrier mounting device 20 is mounted to at least one of the openings 16. The barrier mounting devices 20 provide a means of attaching the barrier 10 to the bollards 12. The number and configuration of barrier mounting devices 20 may vary by the specific embodiment, but in general at least one is required to allow a barrier 10 to be mounted to a bollard 12.

(14) In FIGS. 1, 2, and 2A, the collar 14 shown comprises four openings which in FIG. 1 have three securing elements 18 and one barrier mounting device 20 which in these embodiments is an eye bolt. However, it is understood that the type of barrier mounting device 20 could be any device that a barrier 10 may connect to such as a hinge, a clip, a hook, a latch, a quick connect coupling, a carabiner, etc.

(15) FIG. 1 also shows that a plurality of collars 14 are arranged along the length of the bollard 12. The barrier 10 is attached to the barrier mounting device 20 of each collar 14. It is conceivable that a plurality of like barriers 10 may be strung between a series of bollards 10 in which case a single bollard 10 may be support two barriers 10 on either side. In such a configuration, each collar 14 would have two securing elements 18 with two barrier mounting devices 20. It will be understood that the combination of the number of openings 16, the number, type, configuration, and arrangement of securing elements 18 and barrier mounting devices 20 may be varied with the particular embodiment. In order to aid the mounting of securing elements 18 and barrier mounting devices 20, nuts may be bonded, fused, soldered, welded or otherwise attached to the openings 16.

(16) The type of barrier 10 may also be varied. FIG. 1 shows a barrier 10 that is net, but other types may be used such as meshes, solid barriers, or gates. In every case, so long as the barrier mounting device 20 is capable of receiving the barrier 10, the collar 14 should be able to support the barrier 10. It is conceivable that a bollard 10 may not be adjacent to another bollard but to a wall or other surface that is generally parallel to it. In such cases, the other side of the barrier may not mount to another bollard but to the wall or other surface.

(17) The collars 14 are typically manufactured out of materials strong enough to support the weight of the barriers 10 and in any case should be strong enough to serve the intended purpose of the barriers 10. The elements of the collar assembly may be manufactured out of steel, aluminum, plastic, or combinations thereof.

(18) The collars 14 shown in FIGS. 1, 2, and 2A are unitary pieces that can slide over bollards 12 that have no obstructions on them. However, there are instances where it is impossible to install such collars 14 due to space constraints or other impediments that may be mounted to or part of the bollard 12. In such instances, the embodiment of collar 10a shown in FIGS. 3 and 3A may be helpful. The collar 10a comprises multiple pieces that may be slipped around a bollard. In this embodiment, the collar 10a comprises two halves that have bolt holes 22a which are aligned together to receive fasteners 24a that hold the two halves of the collar 10a together. The type of fastener 24a is shown to be a bolt but other types of fasteners that can securely hold the collar 10a together may be used.

(19) This embodiment of collar 10a has the same number of openings 16a as with the earlier embodiments and depicts a barrier mounting device 20a that is an eyebolt. It will be understood that the combination of the number of openings 16a, the number, type, configuration, and arrangement of securing elements 18a and barrier mounting devices 20a may be varied by the particular embodiment. In order to aid the mounting of securing elements 18a and barrier mounting devices 20a, nuts may be bonded, fused, soldered, welded or otherwise attached to the openings 16a.

(20) The collars shown in FIGS. 1-3A have a circular cross-section. Generally, a collar with a circular cross-section is sufficient to fit around most bollard shapes—even those bollards which themselves are not circular in cross-section. So long as the securing elements can securely mount the collar to the bollard, the shape of the collar is immaterial. However, it is possible to have collars with other cross-sectional shapes. FIG. 4 shows a collar 10b that has a square cross-section. It will be understood that other cross-sectional configurations are also possible such as rectangles, triangles, and other shapes.

(21) This embodiment of collar 10b has the same number of openings 16b as with the earlier embodiments and depicts a barrier mounting device 20b that is a hook. It will be understood that the combination of the number of openings 16b, the number, type, configuration, and arrangement of securing elements 18b and barrier mounting devices 20b may be varied by the particular embodiment. In order to aid the mounting of securing elements 18b and barrier mounting devices 20b, nuts may be bonded, fused, soldered, welded or otherwise attached to the openings 16b.

(22) The collar shown in FIGS. 1-4 are generally sized to have a length that fits its openings in a single dimension, but it will be understood that the length of the collar could be larger. In the embodiment shown in FIG. 5, the collar 14c is extended to form a sleeve that encompasses the entire bollard 12c (as can be seen in the cut-away in the drawing). This configuration allows for sturdier and heavier barriers 10c to be mounted between bollards 12c. These collars 14c may also serve as aesthetic improvements to the bollards 12c they cover. If the bollards 12c are not structurally sound, the collars 14c could also provide structural support for bollards 12c. The collars 14c could also be bolted or otherwise secured directly to the ground with bolts 26c if additional security is required.

(23) As with earlier embodiments, securing elements 18c are installed in openings that run along the length of the collar 14c to secure each collar 14c to the bollard 12c inside it. The barrier mounting devices 20c may be sturdier than other embodiments and in FIG. 5, they comprise a hinge one collar 14c and a latch on the other. The barrier 10c in this embodiment that is mounted to the barrier mounting devices 20c is a gate that is sized to span the distance between the two adjacent bollards 12c.

(24) It will be understood that the combination of the number of openings 16c, the number, type, configuration, and arrangement of securing elements 18c and barrier mounting devices 20c may be varied by the particular embodiment. In order to aid the mounting of securing elements 18c and barrier mounting devices 20c, nuts may be bonded, fused, soldered, welded or otherwise attached to the openings 16c.

(25) This invention has been described with reference to several preferred embodiments. Many modifications and alterations will occur to others upon reading and understanding the preceding specification. It is intended that the invention be construed as including all such alterations and modifications in so far as they come within the scope of the appended claims or the equivalents of these claims.
