Description

1. Field of the Invention
The present invention relates to devices used to manually lift and carry objects.
2. Description of Prior Art
Since time immemorial, man has had to lift and carry loads. This is usually done with the hands and arms, though heavier loads, in a pack, are sometimes supported by the back, which is stronger than the hands or arms. Absent the pack, however, man has usually had to use his hands and arms to lift and carry loads.
There have been attempts to help man use straps to carry loads (see, e.g. U.S. Pat. No. 2,718,988 to Potts, and U.S. Pat. No. 1,727,873). However, none known to the inventor have the advantages of the present invention, e.g. to optimally: divide between two hands the weight of an article being carried; cause each hand to act like a counterweight to the other; enable sharing loads between the hands, shoulders and especially the back of the user; enable the shifting of loads to the back, and by accomplishing the objects listed below.

OBJECTS OF THE INVENTION

It is a prime object of the present invention to provide an apparatus to assist in manually lifting and carrying objects.
It is another object of the present invention to provide an apparatus to assist in manually lifting and carrying objects which reduces the load and strain on the tendons and muscles of the arms of the user.
It is another object of the present invention to provide an apparatus to assist in manually lifting and carrying objects which transfers to the shoulders and back some of the load of an object being manually lifted or carried.
It is still another object of the present invention to provide an apparatus for aiding in lifting, carrying, and transporting stretchers or gurneys bearing medical patients.
In one embodiment, it is an object of the present invention to provide a “hands-free” capability for manually (e.g. without powered machines) lifting and carrying a load.
It is still another object of the present invention to provide an inexpensive lightweight, portable, easily stored apparatus to accomplish the foregoing and other objects.
It is still another object of the present invention to provide an apparatus, to accomplish the foregoing and other objects, which consists of a limited number of conventional elements which interact reliably and provide an apparatus having a long useful life.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1. illustrates the apparatus of the present invention (generally designated “A”) according to the present invention, as it would appear mounted on the user's body as viewed from the anterior (front) side. The apparatus comprises a first strap 10 and a second strap 12. Straps 10 and 12 are made of a substantially non-stretchable material such as KEVLAR® which is a product available from Dupont, of Wilmington, Del. As an alternative to straps, belts, chains, monofilament fishing lines, etc. or the like could be used.
Strap 10 has a first end 11 and a second end 13; the first end 11 is connected to first strap connector means 18. The second end 13 is connected to second strap connector means 28. Strap 10 has an anterior section 10A and a posterior section 10P.
Strap 12 has a first end 15 and a second end 17; the first end 15 is connected to second strap connector means 28; the second end 17 is connected to first strap connector means 18. Strap 12 has an anterior section 12A and a posterior section 12P. Straps 10 and 12 may be integral, continuous, sectional, or separate and interconnected.
As seen in FIGS. 1-2, 6-7 straps 10 and 12 are generally parallel as they traverse the anterior portion of the user's body, and cross each other as they traverse the posterior portion of the user's body. As seen in FIG. 2, straps 10 and 12 extend across the posterior of the user's body, each passing over a different one of the user's shoulders, preferably supported in part by shoulder pads 24, which are provided to cushion each shoulder. Straps 10 and 12 diagonally traverse the user's back, crossing at a crossover point 22 approximately along the user's spine. In one embodiment, the straps 10 and 12 are retained at crossover point 22 by one or more slots cut lengthwise in one of the straps, with the other strap being threaded through the one or more slots, as shown in FIGS. 2-3.
The first end 15 of strap 12 and the second end 13 of strap 10 are connected at first strap connector means 18. The first strap connector means 18 facilitates the connection of straps. It may take the form of a simple bracket through-bolted through two strap ends (as depicted in FIGS. 1-4) or, alternatively, of structure like a buckle or D-ring or other suitable structure, including, but not limited to, structures disclosed elsewhere herein and/or depicted in FIG. 5.
Likewise, the first end 11 of strap 10 and the second end 17 of strap 12 are connected at second strap connector means 28, The second strap connector means 28 facilitates the connection of straps. It may take the form of a simple bracket through-bolted through two strap ends (as depicted in FIGS. 1-4) or, alternatively, of structure like a buckle or D-ring or other suitable structure, including, but not limited to, structures disclosed elsewhere herein and/or depicted in FIG. 5.
Aside from the straps, strap connectors 18, 28 are each connected to a different one of two load engaging means 20, 30, respectively, as is best seen in FIGS. 3-4. The first load engaging means 20 may take the form of a patch of non-slip rubber-like material. This form, which also permits use of the palms and fingers (aided by the apparatus of the present invention) is useful when the object to be lifted or carried is of a nature such that it usually gripped in the palms and/or fingers. An example of such an object is a box full of books (such as seen in FIG. 7) or the handle of an ordinary medical stretcher (such as seen in FIG. 8), or a shovel (such as seen in FIG. 9). Alternative embodiments may use alternative load engaging means, e.g. a clip or hook 20′ or 30′ (such as seen in FIG. 6) to attach to the handle of a heavy equipment suitcase (such as seen in FIG. 6), or to any object having an opening or recess or suitable fitting for the clip or hook to engage to. Indeed, many mating connectors may be used, with one half serving as the load engaging means, and the other half attached to the object to be acted upon.
In one preferred embodiment, first load engaging means 20 is operably connected to strap connection means 16, and second load engaging means 30 is operably connected to apparatus strap connection means 26 (see, e.g., FIG. 6).
In one preferred embodiment, preferably located at or near strap connection means 18 is first means adapted to be engaged by at least one of a portion of one of the user's arms 16, e.g., the hand; preferably located at or near strap connection means 28 are second means adapted to be engaged by at least one of a portion of one of the user's arms 26, e.g., the hand.
In the embodiment illustrated in FIGS. 1-4, the first means adapted to be engaged by a portion of one of the user's arms 16 is a loop into which the four fingers of the hand are placed, with the thumb outside the loop. This permits the hands, fingers, palms, wrists, arms etc. to all be employed in the usual way to pick up the exemplary box, with the important difference that now the forces needed to lift and or hold the box are not just along the muscles and tendons of the arm, but also across the shoulders and back of the user (Of course, other structures than a hand loop could be used, e.g. a full or partial glove, a ring, a thumb loop, a forearm or wrist cuff, etc.)
FIG. 5 depicts an alternative embodiment of the apparatus of FIGS. 1-4 in which a D-Ring is the strap connector means 18, which may support the load engaging means 20 (or, in some cases, itself serve as the load engaging means 20).
FIG. 6 depicts the device according to FIG. 1 in which the load engaging means takes the form of a hook 20′ and a hook 30′, and is used to carry a heavy suitcase by the handle.
FIG. 7 depicts the device according to FIG. 1 in which a non-slip material is used as load engaging means 20, and is used (in conjunction with the user's supporting hand underneath) to help carry a heavy box.
FIG. 8 depicts the apparatus according to FIG. 1 being used to carry a medical stretcher. While only one stretcher bearer is using the apparatus according to the present invention, both stretcher bearers could use the it.
FIG. 9 depicts the apparatus of FIG. 1 being used to hold a shovel.
FIG. 10 depicts additional views of the apparatus of FIG. 1.
While only a limited number of preferred embodiments of the present invention have been disclosed for purposes of illustration, it is obvious that many variations and modifications could be made therein. It is intended to cover all of these variations and modifications which fall within the scope of the present invention as defined by the following claims.
