The field to which the following disclosure generally relates includes pickup trucks and more particularly, may include pickup trucks with bed caps or other structures attached over the pickup's bed.
Many pickup truck owners attach covers, caps, campers, protective liners, or other structures over the pickup's bed for a variety of purposes. The typical manner of attaching such a structure includes drilling through the bed rail and extending bolts through the resulting holes and through aligning holes in the structure. This provides a suitable method of securing the structure to the pickup, but results in rough holes through the pickup rails that may become undesirable if the structure is removed.
Another method of attaching a structure over a pickup's bed involves the use of clamps. The damps secure the structure to the bed rail and avoid the need to drill holes. However, clamps do not provide direct interference against relative sliding between the bed rail and the structure but instead rely on friction and the pressure applied by the clamp. As a result, the damps may effect localized denting where they apply pressure to the bed rails. These localized dents may also become undesirable if the structure is removed from the bed.
A number of variations as described herein may include a product and a method for securing a structure to a pickup truck in a damage-free way. The pickup may have a bed rail with a stake pocket that has walls. An anchor may have an expandable section, with a fastener extending through the expandable section. The anchor may be positioned into the stake pocket. A structure having a mounting flange with a hole in the mounting flange may be positioned onto the bed rail so that the fastener extends through the hole. The fastener may be secured to compress the expandable section and simultaneously clamp the mounting flange to the bed rail. The structure may be secured on the bed rail by forcing the expandable section against the walls of the stake pocket and capturing the mounting flange against the bed rail with the fastener.
According to a number of other variations described herein a method may include the steps of providing a pickup truck having a bed rail that has a stake pocket with walls. The stake pocket may provide an opening through the bed rail. An anchor assembly may be provided that may be configured to secure a structure to the bed rail. The anchor assembly may have an elastic element that may have an opening. A bolt with threads may be positioned through the opening so that the threads extend out of the elastic element. The anchor assembly may be positioned in the stake pocket so that the threads extend out of the stake pocket. The structure may be positioned onto the bed rail so that the bolt extends through an opening in the structure. A fastener may be applied to the bolt threads and tightened, expanding the elastic element against the walls of the stake pocket and securing structure to the bed rail.
In a number of other variations described herein a product may be defined for securing a structure to a pickup bed. A bed rail may have a stake pocket with walls. The stake pocket may present an opening through the bed rail. An anchor assembly may be positioned in the stake pocket and may be configured to secure the structure to the bed rail. The anchor assembly may have an elastic element that defines an opening. A bolt may be disposed within and may extend through the opening so that the bolt extends out of the elastic element and the stake pocket. The structure may be positioned on the bed rail so that the bolt extends through a hole in the structure. A fastener may be coupled with the bolt. The elastic element may be compressed by the bolt and expanded against the walls of the stake pocket, securing the structure to the bed rail.
Other illustrative variations within the scope of the invention will become apparent from the illustration and the detailed description provided herein. It should be understood that the illustration, the detailed description and any specific examples, while disclosing variations within the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Select examples of variations within the scope of the invention will become more fully understood from the detailed description and the accompanying drawing, wherein:
The FIGURE is a schematic cross sectional illustration of part of a vehicle's bed rail with an anchoring structure according to a number of variations.
The following description of the variations is merely illustrative in nature and is in no way intended to limit the scope of the invention, its application, or uses.
The use of pickup trucks may include a number of purpose built structures that are placed over the bed of the pickup. The structure may be a cap with a low profile that provides a means of securing the contents of the bed, or may be a cap that has a height about the height of the cab of the pickup, or may be a camper that extends above the height of the cab, or may be yet another structure that secures articles or protects the bed from wear or from the weather. For some structures, rather than extending upward, the structure may extend over the bed rail and downward into the bed of the pickup. For the variety of structures, there exists a need to secure the structure to the pickup. According to a number of variations,
The box 14 may include an outer wall 15 with an outward facing styling surface 16, and an inner box wall 18. A bed rail 20 may be formed between the outer wall 15 and the box wall 18 presenting a relatively flat horizontal surface that extends along the sides of the pickup's box. The bed rail 20 may be provided with a number of stake pockets 22. Stake pockets may be provided for inserting the stakes of a stake and rail structure for accommodating loads that are taller than the pickup bed itself. The stake pocket 22 may have four side walls 24 and a bottom 26, and may exhibit an opening 28 that presents itself through the bed rail 20.
An anchor assembly 30 may be inserted into the stake pocket 22 and may include an elastic element 32, able to resume its normal shape spontaneously after distortion. The elastic element 32 may be sized to closely fit within the walls 24 of the stake pocket 22 so that friction will hold it in a vertical position against its own weight when inserted. The elastic element 32 may also have a longitudinal opening 33 that extends completely through its body, and at least a section of the elastic element 32 may be expandable. Anchor assembly 30 may include an upper compression plate 34 and a lower compression plate 36, each being rigid and sized to fit within the stake pocket 22 with clearance, and each having a central hole 37, 38. A bolt 40 may have an enlarged head 41 or may be otherwise engaged with the lower compression plate 36. The bolt 40 may extend through the hole 38 of lower compression plate 36, the longitudinal opening 33 of elastic element 32, and the hole 37 of the upper compression plate 34. A fastener in the form of a nut 42 may be attached to the bolt 40. By tightening the nut 42, the compression plates 34, 36 are forced toward one another compressing the elastic element 32. As elastic element 32 is compressed it may be urged to expand laterally, pressing against the walls 24 of the stake pocket 22, securing the anchor assembly 30 in place.
To secure the structure 12 on the pickup box 14 the anchor assembly 30 may be inserted into the stake pocket 22 with the threaded end of bolt 40 extending upward above the bed rail 20. The anchor assembly 30 may be inserted so that the upper compression plate 34 is approximately level with the bed rail 20 and then the nut 42 may be removed. Optionally, prior to insertion of the anchor assembly 30, a resilient plate 44 having an aperture or opening that has a diameter smaller than the diameter of the bolt 40 may be applied over the bolt 40 on top of, and adjacent to, the upper compression plate 34. The resilient plate 44 may provide protection for the upper surface of the bed rail 20 and may help hold the anchor assembly 30 and/or bolt 40 in its vertical position in the stake pocket 22 during positioning of the structure 12.
The mounting flange 11 of the structure 12 may be provided with a number of sized holes or openings 46 corresponding to the number of anchors to be used. Once the anchors are in position in the stake pockets and the nuts are removed, the structure 12 may be positioned and lowered into place with the bolt 40 extending through the opening 46. Once in position, the nut may be placed back on the bolt 40 and tightened. As nut 42 is attached and tightened, lower compression plate 36 is pulled toward upper compression plate 34 compressing the elastic element 32 in the vertical direction and forcing it to expand in the lateral directions. This forces the elastic element 32 against the walls 24 of the stake pocket 22 and secures the structure 12 to the pickup box 14. Since the bolt 40 extends through the opening 46 in mounting flange 11, the bolt 40 directly interferes with lateral movement of the structure 12 relative to the bed rail 20. The potential for movement may be minimized by providing minimal clearance between the opening 46 and the bolt 40 where the diameter of the opening is only slightly larger than the diameter of the bolt.
