## Background
BACKGROUND
Apparatus and methods for lifting, transporting and relocating assembled non-penetrating anchors are shown and described.
Non-penetrating anchors 12 to provide fall protection for workers working at the edge of a roof or other fall hazards are in general use in industry. Generally, conventional anchors 12 include a plurality of individual weights 16 which are supported and carried by a frame 18 of any suitable type. Frame 18 includes suitable structure such as a ring 14 for attaching a safety lifeline thereto which in turn is connected to a harness worn by the worker. When moving conventional anchors 12 from one location to another, they need to be disassembled. After disassembling, all the component parts (as many as 20-30) need to be moved separately and then reassembled in the new location. Thus, a need exists for a unique carrier for lifting, transporting and relocating the assembled non-penetrating anchor 12 in one piece to a new location on the roof or other fall hazard.
SUMMARY
This need and other problems in the field of fall protection are solved by providing a carrier for lifting, transporting and relocating the assembled non-penetrating anchor in one piece to a new location. Particularly, a frame includes a rear bar and first and second carrier handles connected to the rear bar to define a plane. Wheels are rotatably connected to opposite ends of the rear bar and located outwardly of the first and second carrier handles. First and second abutments are secured to the rear bar intermediate the first and second carrier handles and extend downward for a substantial portion of the radius of the wheels. A swiveling hook is located intermediate the first and second carrier handles and above the plane and spaced in front of the rear bar and has an adjustable spacing from the plane. With the carrier handles not pivoted by the user, the ring of the assembled anchor can be received in the swiveling hook. The spacing of the swiveling hook can be adjusted, and the swiveling hook, the ring and the assembled anchor can be raised by pivoting the carrier handles about the rear bar.
The swiveling hook is pivotally connected to an adjuster clevis received in a tube having a handle nut threadably received thereon. The tube is intermediate the swiveling hook and the handle nut and is connected to a U-shaped support secured to the first and second carrier handles and extending therefrom to an elevation.
Each abutment includes a plate extending parallel to the carrier handles and extending from the rear bar for a substantial portion of the radius of the wheels. The rear bar extends through a hole in the plate and is fixed to a tab extending from the plate parallel to the rear bar and having a substantially shorter height.

DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
A carrier 10 includes a generally rectangular frame 24 including a rear bar 26, a front bar 28 extending generally parallel to but spaced from rear bar 26, and carrier handles 30 extending generally perpendicularly between rear and front bars 26 and 28, with rear and front bars 26 and 28 and carrier handles 30 defining a plane. Rear and front bars 26 and 28 are spaced greater than a length of the assembled anchor 12. In the form shown, front bar 28 is in the form of a channel having U-shaped cross sections, carrier handles 30 are tubular having circular cross sections, while rear bar 26 is in the form of a solid rod of solid circular cross sections. Posts 32 generally project perpendicularly from front bar 28 initially in the plane of bars 26 and 28 and carrier handles 30 and include grips 34 extending at an obtuse angle downwardly at the free ends. Posts 32 are located intermediate first and second carrier handles 30 and in a parallel spaced relation. Posts 32 and hand grips 34 are tubular with circular cross sections.
Wheels 40 are rotatably mounted to the opposite ends of rear bar 26 outwardly of carrier handles 30. Wheels 40 each have a radius, and the spacing between wheels 40 is greater than the spacing between first and second carrier handles 30 and greater than the width of the assembled anchor 12. First and second carrier handles 30 are intermediate wheels 40 and have a spacing greater than the width of the assembled anchor 12 but less than the spacing of wheels 40. One or more lift rings 42 can be provided on the bottom of front bar 28 and extending opposite to U-shaped support 50 and adapted to be connected to a hoist line for lifting carrier 10 onto the roof or other fall hazard.
Carrier 10 further includes a swiveling hook 20 for engaging with and receiving ring 14 of anchor 12 and located intermediate first and second carrier handles 30 and spaced from rear bar 26. Suitable provisions movably support swiveling hook 20 relative to frame 24 to provide an adjustable spacing from the plane defined by rear and front bars 26 and 28 and carrier handles 30. In the form shown, a generally U-shaped support 50 is secured to first and second carrier handles 30 and extends from frame 24 intermediate bars 26 and 28 to an elevation opposite abutments 60 and the roof or other fall hazard and greater than the height of the assembled anchor 12. Particularly, support 50 includes a beam 50a extending generally parallel to and spaced from bars 26 and 28 and secured to carrier handles 30 by first and second braces 50b extending generally perpendicularly from the opposite ends of beam 50a. In the form shown, beam 50a and braces 50b are tubular having rectangular cross sections. A tube 52 is secured to beam 50a generally centrally between braces 50b and generally parallel thereto. Swiveling hook 20 is pivotally secured to an adjuster clevis 54, with a handle nut 22 threadly received on adjuster clevis 54 and located on the opposite side of tube 52 than swiveling hook 20. Swiveling hook 20 is located at the height of the assembled anchor 12 and in particular ring 14 thereof when first and second carrier handles 30 are in a normal position not pivoted by a user with grips 34 abutting the roof or other fall hazard upon which wheels 40 are located. First and second carrier handles 30 are pivotable about rear bar 26 from the normal position to a moving position, raising swiveling hook 20 relative to rear bar 26 opposite to abutments 60 and the roof or other fall hazard.
First and second abutments 60 are secured to rear bar 26 inside and adjacent to carrier handles 30 and extend toward but spaced from the roof or other fall hazard. In particular, abutments 60 extend for a distance from rear bar 26 which is a substantial portion of the radius of wheels 40 such as over 50% of the radius of wheels 40 and specifically less than the radius of wheels 40 so as not to engage the roof or other fall hazard on which wheels 40 are located but sufficient to present an obstacle to prevent the assembled anchor 12 from moving therebeyond. In the form shown, each abutment 60 includes a plate 60a extending parallel to first and second carrier handles 30, extending from rear bar 26, and having a plate height perpendicular to rear bar 26 for the substantial portion of the radius of wheels 40. A tab 60b extends generally perpendicular from plate 60a and parallel to rear bar 26. Tab 60a has a height perpendicular to rear bar 26 substantially shorter than the height of plate 60 and specifically about double the cross section of rear bar 26. A hole 60c extends through plate 60a adjacent to tab 60b, with rear bar 26 extending through hole 60c and fixed to tab 60b. 
For the sake of explanation, it will be assumed that carrier 10 is spaced from anchor 12 and is resting upon a roof or other fall hazard such as being supported by wheels 40. The user steps between posts 32 and grasps grips 34 with his hands and pivots frame 24 about rear bar 26 extending along the rotation axis of wheels 40. Posts 32 and carrier handles 30 act as a lever in providing a mechanical advantage. With carrier 10 pivoted such that grips 34 are elevated, carrier 10 is positioned over an assembled non-penetrating anchor 12 and pulled back over the anchor 12 until swiveling hook 20 engages the ring 14 of the anchor 12. Carrier handles 30 are lowered until grips 34 rest upon the roof or other fall hazard. Then, the operator turns handle nut 22 on top of carrier 10 to lift the assembled anchor 12 off the roof or other fall hazard. The operator can then lift carrier handles 30 of the carrier 10 and move the assembled anchor 12 to a new location. In the event that the hooked assembled anchor 12 should rotate about an axis defined by adjuster clevis 54, the assembled anchor 12 will abut against one abutment 60 which will stop the assembled anchor 12 from rotating. After positioning the assembled anchor 12 where it needs to be, the operator lowers the carrier handles 30 until grips 34 rest upon the roof or other fall hazard, walks over to handle nut 22 on top of carrier 10 and turns handle nut 22 to lower the assembled anchor 12 back down on the roof or other fall hazard. The operator then moves carrier 10 forward to disengage swiveling hook 20 from ring 14 and moves the unloaded carrier 10 off to the side.
Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
