DETAILED DESCRIPTION
[0016] As show in Fig. 1, a removable speed bump 10 is mounted on pavement 1. The pavement 1 may be any surface on which vehicles are driven. The speed bump 10 has a top surface 12 and a bottom surface 14 in contact with the pavement 1. The removable speed bump 10 also has anchor holes 16 which are exposed on both the top surface 12 and bottom surface 14. The removable speed bump 10 has ends 18 which form the ends of the speed bump 10.
[0017] Figs.2 and 3 show a front view and side view of the removable speed bump 10 of Fig. 1. The speed bump 2 has a total length, designated LT in Fig. 2 of between 1.0 and 10.0 feet, for example 6 feet. The speed bump 10 has a height, designated Hs in Fig.3 of between 1.0 and 4.0 inches, for example 2.5 inches. The outline of anchor assembly 20 is shown in Figs.2 and 3. A removable assembly 20 of the present invention fastens the removable speed bump 10 to the pavement 1. Anchor holes 16 have a center to center spacing along the length of the speed bump designated as LA in Fig. 2. LA may between 1.5 and 3.0 feet, for example 2.0.
[0018] Fig. 4 shows a cross section of the removable speed bump 10 along one of the anchor holes 16. Anchor hole 16 has a diameter shown as DA of between 0.50 and 0.75 inch, for example 0.625 inch. A countersunk portion 17 is located at the transition from anchor hole 16 to top surface 18. The countersunk portion 17 has a substantially flat bottom surface and a diameter identified as Dc in Fig. 4 that is greater than the diameter DA- DC is between 1.25 and 1.50 inches, for example 1.375 inches. Bore holes 2 in pavement 1 are spaced and arranged so that they are substantially aligned with anchor hole 16. The bore holes 2 in pavement 1 have a diameter identified as DB in Fig. 4 of between 0.50 and 0.75 inch, for example 0.625 inch.
[0019] Details of a removable anchor system 20 are shown in the embodiment illustrated in Fig.4. The anchor system 20 includes a bolt 24 running through the anchor hole 16, washer 26 sits flush in countersunk portion 17 and bolt head 24a rests upon washer 26. An expander 22 is positioned in bore hole 2. In the embodiment shown in Fig.4, a drop in style of anchor is used. The anchor system 20 has an expander 22 positioned within the bore 2. The expander 22 has expansion slots 28. The expansion slots 28 allow the lower portion of the expander 22 to have a slight inward taper so that it may be inserted into bore hole 2. Once positioned within the bore the expander 22 can be set in place. The expander is set by inserting the expander disc 30 into the expander and striking the expander disc 30 with a setting tool (not shown) and hammer (not shown). The force applied by this action slides expander disc 30 down into the expander 22 the expansion slots 28 open and the diameter of the expander 22 increases so that is come into pressing engagement with the diameter of the bore DB and becomes locked or set into the bore 2. The bolt 24 may then be inserted through the anchor hole 16. A distal end of the bolt 24 has a threaded portion 24b which has male threads. This threaded portion 24b is inserted into the expander 22. The expander 22 has female threads which receive the bolt. A cap 50 may be placed in the countersunk portion 17 to cover the bolt head and provide a finished look and protect the bolt head 24a of the removable speed bump 10. It should be appreciated that most standard concrete anchors can be used in this application. A drop in type of anchor is illustrated in Fig.4, but other anchors may be used. For example, wedge anchors and sleeve anchors may be used.
[0020] In another embodiment of the present invention shown in Fig. 5, a vehicle impediments in the form of removable parking blocks 40 fastened to the pavement 1 are shown. The removable parking blocks 40 have parking block anchor holes 46. Dimensions of the removable parking blocks 40 and spacing of the parking block anchor holes 46 may be similar to the above-mentioned dimensions of the removable speed bump. However, the removable parking blocks 40 are substantially shaped to deter vehicle traffic while a removable speed bump 10 is shaped to allow vehicles to pass over the speed bump at a slow speed. The parking block has a parking block bottom surface 44, parking block sides 49 and parking block upper surfaces 48.
[0021] The removable parking block 40 may be held in place with a removable anchor system 20 as shown in Fig. 6. Dimensions of the parking block anchor holes 46 are substantially the same as those mentioned above for the anchor holes 16 of the removable speed bump 10 mentioned above. A parking block anchor hole 46 with a parking block countersunk portion 47 extends from an uppermost parking block top surface 40 to the parking block bottom surface 44. The removable parking block 40 may be fastened to the pavement 1 in a similar fashion as described for the removable speed bump 10. Shown in the embodiment in Fig. 6 is a removable anchor system 20 having an expander 22 set in a bore 2 in the pavement 1 with an expander disc 30. The bolt 24 is inserted through washer 26 which seats in parking block countersunk portion 47. A threaded distal end of the bolt 24 screws into female threads of the expander 22 to fasten the removable parking block 40 to the pavement 1. A cap 50 may be placed in the countersunk portion 17 to cover the bolt.
[0022] As mentioned above one benefit of having removable vehicle impediments, such as removable speed bumps 10 or removable parking blocks 40, is the ability to remove the impediments during winter months so snow plowing can be performed unobstructed. In one embodiment of the present invention shown in Fig. 7, removing the bolt 24 allows the speed bump 10 or parking block 40 to be removed and stored for the winter. A plug 60 can then be inserted into expander 22. The plug 60 may be adapted to fit other anchors which may be used. The plug 60 will keep dirt and other debris from filling expander 22 during the winter months and allow for easy re-installation of the removable speed bump 10 or removable parking block 40 when permitted.
[0023] Whereas particular embodiments of this invention have been described above for purposes of illustration, it will be evident to those skilled in the art that numerous variations of the details of the present invention maybe made without departing from the invention as defined in the appended claims.
