In some embodiments, at least one chock opening 10 and raised chock opening rim 11 may extend from the chock flange 6. The chock openings 10 and chock opening rims 11 may impart friction between the wheel 47 (FIG. 8) of the vehicle 44 and the chock front panel 5 of the chock 2 when the chock 2 is wedged between the vehicle wheel 47 and the surface 50, as illustrated in FIG. 8.
As illustrated in FIGS. 2 and 3, the chock 2 may have a chock interior 14. A tether reel 16 may be mounted for rotation inside the chock interior 14 according to the knowledge of those skilled in the art. As illustrated in FIGS. 2 and 3, in some embodiments, the tether reel 16 may be mounted for rotation within a plane which is parallel or adjacent to the plane of the chock rear panel 4 of the chock 2. In some embodiments, the tether reel 16 may be mounted for rotation on the chock rear panel 4 according to the knowledge of those skilled in the art. In other embodiments, the tether reel 16 may be mounted in alternative orientations or positions in the chock interior 14.
As illustrated in FIGS. 4 and 5, in some embodiments, the tether reel 16 may have a conventional design with a pair of spaced-apart, parallel tether reel flanges 17. A cylindrical tether reel spool 18 may extend between the tether reel flanges 17. The chock tether 22 may be wound on the tether reel spool 18 between the tether reel flanges 17 of the tether reel 16. A tether reel axle 19 (FIG. 4) may mount the tether reel 16 for rotation within the chock interior 14 of the chock 2 according to the knowledge of those skilled in the art. As illustrated in FIG. 3, the chock tether 22 may extend from the tether reel 16 at least through the outside tether opening 8 in the chock side panel 3 of the chock 2. As illustrated in FIG. 1, a tether eyelet 23, having an eyelet opening 24, may terminate the unwound, extending or distal end of the chock tether 22 outside the chock interior 14 for purposes which will be hereinafter described. In some embodiments, the tether reel 16 may be spring-loaded according to the knowledge of those skilled in the art. As illustrated in FIGS. 3 and 4, a tether reel spring 20 may engage the tether reel 16. Accordingly, the tether reel 16 may normally tend to wind the chock tether 22 on the tether reel spool 18 of the tether reel 16. A non-limiting example of a tether reel 16 which is suitable for the apparatus 1 can be obtained from John Evans' Sons of Lansdale, Pa.
As further illustrated in FIGS. 2 and 3, in some embodiments, a reel box 26 having a box interior 31 may be provided in the chock interior 14 of the chock 2. The tether reel 16 may be mounted for rotation in the box interior 31 of the reel box 26 according to the knowledge of those skilled in the art. As illustrated in FIG. 2, the reel box 26 may include, for example and without limitation, a bottom box panel 27 which extends forwardly from a lower edge 4a of the chock rear panel 4 into the chock interior 14 and a front box panel 28 which extends between the bottom box panel 27 and the sloped chock front panel 5 of the chock 2. As further illustrated in FIG. 2, in some embodiments, the tether reel axle 19 may rotatably mount the tether reel 16 between the front box panel 28 of the reel box 26 and the chock rear panel 4 of the chock 2. As illustrated in FIG. 3, the reel box 26 may further include a pair of spaced-apart side box panels 29 which extend between the bottom box panel 27 of the reel box 26 and the chock front panel 5 of the chock 2. As further illustrated in FIG. 3, an inside tether opening 30 may extend through one of the side box panels 29 of the reel box 26. The inside tether opening 30 may be disposed in substantial alignment or registration with the outside tether opening 8 provided in the chock side panel 3 of the chock 2. Accordingly, the chock tether 22 may extend from the tether reel 16 through the inside tether opening 30 in the side box panel 29 of the reel box 26 and through the registering outside tether opening 8 in the chock side panel 3 of the chock 2, with the tether eyelet 23 (FIG. 1) terminating the chock tether 22 outside the chock interior 14. In alternative embodiments, the reel box 26 may be omitted or may have any of a variety of other shapes, designs and/or positions within the chock interior 14 which are consistent with the functional requirements of the chock deployment apparatus 1. The reel box 26 may be fabricated of aluminum, steel, composite materials, plastics such as polypropylene or high-density polyethylene, and/or other materials which are consistent with the functional requirements of the apparatus 1.
Referring again to FIGS. 6-8 of the drawings, in typical application of the chock deployment apparatus 1, the chock mount bracket 34 is attached to the vehicle 44. In some applications, the vehicle 44 may include a flatbed trailer having a vehicle frame 45 and vehicle wheels 47 (one of which is illustrated), each of which may be covered with a wheel well 46. In other applications, the vehicle 44 may include a flatbed truck or other type of vehicle or movable. The chock mount bracket 34 may include a pair of parallel, spaced-apart bracket arms 35. A spanning bracket segment 36 may extend between the bracket arms 35. A pair of bracket mount flanges 37 may terminate the respective bracket arms 35. The bracket mount flanges 37 may be attached to the vehicle frame 45 of the vehicle 44 via a pair of bracket mount bolts 38, for example and without limitation.
In some applications, the tether eyelet 23 which terminates the chock tether 22 may be secured between one of the bracket mount flanges 37 of the chock mount bracket 34 and the vehicle frame 45 of the vehicle 44. Thus, the bracket mount bolt 38 may be extended through a bolt opening (not illustrated) in the bracket mount flange 37 and then through the registering eyelet opening 24 (FIG. 1) of the tether eyelet 23, and then extended or threaded into a corresponding registering bolt opening (not illustrated) in the vehicle frame 45, and may be secured with a nut (not illustrated).
As illustrated in FIGS. 6 and 7, when not in use, the chock 2 may be deployed in a storage configuration in which it is stowed in the chock mount bracket 34. Accordingly, the chock 2 may initially be oriented in an inverted position above the chock mount bracket 34 with the chock flange 6 extending downwardly toward the surface 50 (FIGS. 6-8). The chock 2 may then be lowered through and nested in the chock mount bracket 34 with the chock rear panel 4 of the chock 2 facing upwardly. Thus, the chock front panel 5 may engage the upper edge of the spanning bracket segment 36 of the chock mount bracket 34 such that the chock 2 is cradled in the chock mount bracket 34, as illustrated in FIGS. 6 and 7.
When use of the chock 2 is desired to prevent the wheels 47 of the vehicle 44 from inadvertently rolling and the vehicle 44 from moving on the surface 50, such as when the vehicle 44 is parked, the chock 2 may be lifted from the chock mount bracket 34, pulled away from the chock mount bracket 34 and placed or wedged between the vehicle wheel 47 and the surface 50, as illustrated in FIG. 8. The chock 2 is typically placed on the side which is down slope from the vehicle wheel 47. As the chock 2 is lifted from the chock mount bracket 34 and pulled away from the vehicle 44 toward the vehicle wheel 47, the chock tether 22 may unwind from the tether reel 16 as the tether reel 16 typically rotates in the reel box 26 inside the chock interior 14 of the chock 2 and the chock tether 22 extends out from the chock 2 through the inside tether opening 30 (FIG. 3) in the side box panel 29 of the reel box 26 and the aligned outside tether opening 8 in the chock side panel 3 of the chock 2. The chock 2 may be oriented such that the chock side panels 3 and the chock rear panel 4 rest on the surface 50 and the vehicle wheel 47 of the vehicle 44 engages the chock front panel 5. Thus, the chock 2 remains wedged in place between the vehicle wheel 47 and the surface 50 to prevent inadvertent movement of the vehicle 44 on the surface 50. In some applications, the chock opening rims 11 which protrude from the chock front panel 5 of the chock 2 may impart friction against the vehicle wheel 47 to prevent the vehicle wheel 47 from slipping against the chock 2. The chock 2 may remain tethered or attached to the vehicle 44 through the chock tether 22, which may prevent or minimize the likelihood of loss, misplacement or theft of the chock 2.
When transport of the vehicle 44 is subsequently desired, the chock 2 is removed from between the vehicle wheel 47 and the surface 50 and stowed back in the chock mount bracket 34, as illustrated in FIGS. 6 and 7. As it is lifted from the surface 50 into proximity to the chock mount bracket 34, the chock tether 22 may be wound on the tether reel 16 as it is retracted through the outside tether opening 8 and the inside tether opening 30. Therefore, the chock 2 remains tethered to the vehicle 44 through the chock tether 22 and ensures that the chock 2 is available when needed.
While illustrative embodiments of the disclosure have been described above, it will be recognized and understood that various modifications can be made and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the disclosure.
