Safety strap apparatus to protect a super single truck rim from damage during a tire blowout

Abstract

A safety strap apparatus for use with a vehicle's super single tire to protect a rim of the tire from damage during a tire blowout is provided. The super single tire and rim are coupled to an axle mechanically coupled to a frame of the vehicle by a shock absorber. The safety strap apparatus includes a strap assembly having a first elongated strap coupled to a second elongated strap, the strap assembly having a left end portion having an overlapped portion with end portions of the first and second elongated straps and a right end portion including another end portion of the first elongated strap, the left and right end portions being coupled together to create a loop. The loop is disposed around top and bottom portions of the shock absorber. Tension in the strap assembly supports the rim above the ground during the tire blowout.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

(8) As depicted in FIGS. 1-3, safety strap apparatus 10 is configured for use with a vehicle such as a commercial truck (not shown) to protect tire 14 and rim 16 from damage during a tire blowout. In use, safety strap apparatus 10 is disposed around upper and lower portions of shock absorber 12, which is coupled to tire axle 28 and truck frame 36 by mounting brackets 22 and mechanical fasteners such as bolts. Tire 14 is preferably a super single tire used for trucks. However, safety strap apparatus 10 may be beneficial for use with alternative types of tires known in the field.

(9) As depicted in FIG. 1, safety strap apparatus 10 comprises a strap assembly comprising first elongated strap 30 and second elongated strap 32, which are both preferably made from heavy-duty nylon. However, other high-strength polymers or materials known in the field may be used. First and second elongated straps 30, 32 are aligned and coupled together by primary stitching members 26 such that a left end portion of the strap assembly comprises end portions of first and second elongated straps 30, 32 and a right end portion of the strap assembly comprises another end portion of first elongated strap 30. In one embodiment, primary stitching members 26 are oriented generally parallel to each other and located proximate opposing side edges of first and second elongated straps 30, 32. In one embodiment, a pair of primary stitching members 26 is located proximate each side edge of first and second elongated straps 30, 32. Primary stitching members 26 are preferably made from commercial grade thread.

(10) The left and right portions of the strap assembly are coupled together by end stitching members 24 to create a loop. End stitching members 24 are preferably made from commercial grade thread. In a preferred embodiment, end stitching members 24 comprise a plurality of stitching members oriented generally parallel to each other and evenly spaced throughout a width of the left and right end portions of the strap assembly. This configuration of straps and stitching members enhance the strength of first and second elongated straps 30, 32 to withstand a weight load of at least 12,400 lbs.

(11) In certain embodiments, safety strap apparatus 10 is approximately 27″ long, 2½″ wide and ⅜″ thick. However, it shall be appreciated that dimensions of safety strap apparatus 10 may vary to accommodate different sized trucks, tires and/or rims.

(12) In operation, shock absorber 12 is removed from mounting brackets 22 by removing the mechanical fasteners. Safety strap apparatus 10 is disposed around the top and bottom portions of shock absorber 12. Shock absorber 12 is then secured to mounting brackets 22 by the mechanical fasteners. As depicted in FIGS. 2 and 4, safety strap apparatus 10 is depicted in the assembled configuration. During a tire blowout, shock absorber 12 extends vertically, which causes tire axle 28 to drop down. However, as depicted in FIGS. 3 and 5, tension in safety strap apparatus 10 limits the extension of shock absorber 12 and prevents further downward movement of tire axle 28, which maintains gap 20 between rim 16 and ground 18. This action permits safety strap apparatus 10 to support rim 16 above ground 18. As a result, significant damage to rim 16 and tire 14 is prevented or minimized.

(13) FIG. 6 depicts an alternative embodiment of safety strap apparatus 10, which comprises the same materials as discussed in other embodiments. In one embodiment, safety strap apparatus 10 comprises a pair of elongated straps aligned together and coupled by stitching (not shown). Each end of the pair of elongated straps comprises an opening configured to receive bolt 34. Bolts 34 secure safety strap apparatus 10 directly to mounting brackets 22, which secure shock absorber 12 in place. In one embodiment, each opening in the pair of elongated straps is reinforced with a metal eyelet (not shown). The alternative safety strap apparatus 10 limits the extension of shock absorber 12 during a tire blowout, which supports rim 16 above ground 18.

(14) It shall be appreciated that the components of safety strap apparatus 10 described in several embodiments herein may comprise any alternative known materials in the field and be of any color, size and/or dimensions. It shall be appreciated that the components of safety strap apparatus 10 described herein may be manufactured and assembled using any known techniques in the field.

(15) Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
