Installation of the bollard system according to the invention according of the invention will be described in greater detail with reference to FIGS. 1-3. In an exemplary embodiment of the invention, the bollard system according to the invention is installed in a ground 300 having a ground surface 310. In the embodiment shown in FIGS. 1-3, the ground 300 is formed of concrete material. In other embodiments, the ground 300 may be formed of soil, sand, or any other ground material commonly known. In further embodiments, the ground surface 310 may comprise a material different from the ground 300, for example, asphalt or pavers.
A user places the drill bit 240 of the mounting device 200 on the ground surface 310 with the longitudinal direction M aligned with an insertion direction I and, using a tool or manually, turns the drill bit 240 along a rotation direction R. The drill bit 240 displaces material of the ground surface 310 and ground 300 when rotated along the rotation direction R and moves along the insertion direction I, creating a bollard passageway 320 in the ground 300 as shown in FIGS. 2 and 3. The drill bit 240 is rotated and moved along the insertion direction I until, as shown in FIGS. 2 and 3, a bottom surface of the flange 230 abut the ground surface 310. The mounting device 200 is shown in a fully mounted position in the ground 300 in FIGS. 2 and 3.
In an exemplary embodiment of the invention, the pole 100 is then inserted into the mounting device 200. The pole 100 is moved along the insertion direction I and the insertion end 120 of the pole 100 is introduced into the pole receiving passageway 216 of the mounting device 200. The pole attachment device 130 engages the mounting attachment device 220 during insertion. In the embodiment shown in FIG. 2, the locking protrusions 132 are inserted into the protrusion receiving passageways 222 as the pole 100 moves along the insertion direction I. When the insertion end 120 of the pole 100 reaches the embedded end 214 of the mounting body 210 in the pole receiving passageway 216, a user turns the pole 100 along the rotation direction R, positioning each locking protrusion 132 in a portion of one protrusion receiving passageway 222 extending in the direction transverse to the longitudinal direction M.
In the fully inserted position of the pole 100 in the mounting device 200 shown in FIG. 2, to remove the pole 100, a user must first turn the pole 100 counter to the rotation direction R before moving the pole 100 counter to the insertion direction I. The locking protrusions 132 and protrusion receiving passageways 222 secure the pole 100 within the mounting device 200 and ensure that the pole 100 is not accidentally removed from the mounting device 200. The bollard system according to the invention is shown fully installed in the ground 300 in FIG. 2.
The bollard system according to the invention may be used in a variety of barrier applications. In an embodiment, the bollard system according to the invention is used to create a roadblock for a temporary road closure; in this embodiment, the ground 300 is commonly concrete, the pole 100 and mounting device 200 are formed of a metal material, and the pole 100 and mounting body 210 have a larger diameter. In another embodiment, the bollard system according to the invention is used to protect a curb or other road-adjacent element from, for example, a snow plow; in this embodiment, the ground 300 is commonly concrete, the mounting device 200 is formed of a metal material, the pole 100 is formed of a plastic material, and the pole 100 and mounting body 210 have a smaller diameter. In another embodiment, the bollard system according to the invention is used to create a pedestrian barrier at, for example, an outdoor festival; in this embodiment, the ground 300 is commonly soil, the pole 100 and mounting device 200 are formed of a plastic material, and the pole 100 and mounting body 210 have a smallest diameter. In any embodiment, a plurality of bollard system according to the inventions may be installed aligned to create an elongated barrier. One with ordinary skill in the art would understand that these embodiments are merely exemplary and other combinations of materials and sizes of the pole 100 and mounting device 200 may be used.
Whenever the user does not require the barrier protection of the bollard system according to the invention, the user may remove the pole 100 from the mounting device 200. As described above, the pole attachment device 130 is disengageable from the mounting attachment device 220; in the shown embodiment the user first turns the pole 100 counter to the rotation direction R before moving the pole 100 counter to the insertion direction I, moving the locking protrusions 132 along the protrusion receiving passageways 222. The pole 100 is thus removed from the mounting device 200, exposing the pole receiving passageway 216 as shown in FIG. 3.
In an embodiment of the invention, a plug 400, shown in FIG. 3, is insertable along the insertion direction I into the pole receiving passageway 216 of the fully mounted mounting device 200 when the pole 100 is removed and not in use. The plug 400 is a cylindrical member having a surface end 410 and an opposite embedded end 420 along a longitudinal direction G of the plug 400. The plug 400 may be formed from a metal, such as aluminum or steel, a plastic material, such as acrylonitrile butadiene styrene (ABS), or a resilient material such as rubber. The plug 400 is sized to fit the pole receiving passageway 216 and, when the plug 400 is inserted, the surface end 410 is flush with the flange 230. The plug 400 thus creates a continuous, planar surface with the flange 230 along the ground surface 310 to avoid disrupting movement over the ground surface 310 when the pole 100 is not inserted. The plug 400 is removable counter to the insertion direction I to permit the pole 100 to be re-inserted.
A bollard system according to the invention according to another embodiment of the invention is shown in FIG. 4. The bollard system according to the invention includes a pole 100′ and a mounting device 200′. Like reference numbers indicate like elements and only the differences with respect to the pole 100 and mounting device 200 shown in FIGS. 1-3 will be described in detail herein. In further embodiments, the features of the bollard system according to the invention shown in FIG. 4 and described herein are freely interchangeable and combinable with the features of the bollard system according to the invention shown in FIGS. 1-3.
In an embodiment of the invention, shown in FIG. 4, the pole attachment device 130 is a pole thread 134 extending circumferentially around the pole 100. The pole thread 134 extends from the insertion end 120 along part of a length of the pole 100′ in the longitudinal direction P. In the mounting device 200′ shown in FIG. 4, the mounting attachment device 220 is a mounting thread 224 extending circumferentially around an interior surface of the mounting body 210 from the surface end 212 to the embedded end 214 and facing the pole receiving passageway 216. The mounting device 200′ shown in FIG. 4 does not have a drill bit 240 and instead has a flat surface on the embedded end 214 of the mounting body 210.
The bollard system according to the invention shown in FIG. 4 is also installable in the ground 300. A user uses a commonly known, separate drill tool (not shown) to independently create the bollard passageway 320 prior to insertion of the mounting device 200′. The mounting device 200′ is then inserted into the bollard passageway 320 until the flange 230 abuts the ground surface 310. The pole 100′ is insertable into the mounting device 200′ by moving the pole 100′ along the insertion direction I and having the pole attachment device 130 engage the mounting attachment device 220. In the embodiment shown in FIG. 4, the pole thread 134 engages the mounting thread 224 and the pole 100′ is rotated along the rotation direction R to move the pole 100′ along the insertion direction I into the pole receiving passageway 216. The pole 100′ is fully inserted in the pole receiving passageway 216 when the insertion end 120 abuts the embedded end 214 and the pole thread 134 is engaged with the mounting thread 224. The pole 100′ is removable from the mounting device 200′ by rotating the pole 100′ counter to the rotation direction R and disengaging the pole thread 134 from the mounting thread 224. The plug 400 can be inserted into the mounting device 200′ similarly to the insertion of the plug 400 into the mounting device 200 described with reference to FIG. 3.
