Definitions

  • the present invention relates to a lifting and carrying device to be worn by a person, and more particularly, to a lifting and carrying device utilizing guided straps for conveying a load.
  • lifting devices include various straps and pads that place the burden on the neck or shoulders. Some of these devices require a counterbalancing effect in order to perform properly.
  • One example is a strap that is placed around the back of the neck with both ends extending down the front of the body, with a load, such as a bag, applied to each end.
  • Another example is a strap that is hung over one shoulder with a load on the front and another load hung from the back.
  • These schemes require that the first load is substantially equal to the second load, in order to ease carrying and maintain balance. Although they do take the burden off of the hands and arms, they, however, do not promote a balanced configuration and do not provide adequate control over the load. For instance, the straps can easily slide off the shoulder or neck, requiring constant attention and adjustment. Also, since the user determines the placement of the strap on the neck or shoulder, the strap may be placed in a position that is not ergonomically correct, possibly causing injury or undue stress.
  • GB 2,224,193 to Bridge shows one such device in Fig. 4 where a strap hoops about the torso horizontally, buckling in the front, with two vertical straps, each covering one shoulder.
  • the vertical straps act as a shoulder strap, being sewn to the front and back of the horizontal strap, and as a load bearing strap hanging below the horizontal strap.
  • the person is also free to place the straps over any part of the shoulder or neck, either in a correct or, unknowingly, in an incorrect manner.
  • the placement of the straps on the shoulder is also dictated by the sewn-in spacing between the vertical straps on the back portion of the horizontal strap. Even if adjustment is provided in the front, by use of the buckle, the back portion will dictate the placement of the vertical straps, either placed too widely for a person of small stature or too narrowly for a person of large stature.
  • a lifting and carrying device that can be worn by a person for conveying heavy or bulky loads without undue stress or imbalance. What is also needed is a device that is guided to an ergonomically correct and comfortable loading position on the shoulders. Additionally, what is needed is a device that distributes the load over a large surface area of the shoulders. Also, what is needed is a device that can be adjusted to permit use and easy load handling by persons with various lifting preferences.
  • the present invention is directed to a novel lifting apparatus donned by a person for conveying a heavy and/or bulky load easily and without undue strain in a hands-free manner.
  • the present invention also provides guidance to permit an ergonomically correct loading position on the shoulders.
  • the present invention also distributes the load to the shoulders over a large surface area.
  • the present invention provides adjustable load straps that can be selectively lengthened and/or locked in position.
  • an apparatus to be worn by a person with a body for carrying a load attached thereto, comprising a yoke with a right shoulder pad and a left shoulder pad with a connecting structure extending therebetween, a securing means connected to the yoke and together configured for secured strapping about at least a portion of the person's body in a donned configuration, and at least one load strap coupled to the yoke and having a means for attaching the load near at least one end, whereby the yoke is securely donned on the person such that the yoke substantially maintains a desired position under various loading conditions.
  • the yoke is one of the primary features that permits the distribution of the weight over the shoulder in a comfortable and ergonomic manner.
  • the yoke preferably is configured to be worn across the shoulders, covering the shoulders and extending between the shoulders across the back.
  • a U-shaped cutout may be provided to be complementary received by the neck, although various shapes and designs are contemplated in the design of the yoke of the present invention.
  • the yoke is preferably padded to provide additional comfort and stress relief and to substantially distribute the load of the load strap lying over it.
  • the securing means serves to stabilize the yoke in a desired position on the person, such as an ergonomically correct position.
  • the yoke and the securing means act together to securely strap the yoke in position.
  • the securing means is preferably one or more straps that connect to the yoke, wrap about a portion of the body such as the torso, one or both of the arms, or the torso and one or both of the arms. It is preferred that this securing does not wrap just about the neck, which could produce a choking action when tightly strapped or in a loaded configuration. It is important to provide secure strapping that holds the yoke in place, without causing discomfort to the user.
  • the securing means can have one or more removable securing means, such as a clasp, side squeeze buckle, clip, and the like, to allow the person to don or remove the apparatus.
  • removable securing means such as a clasp, side squeeze buckle, clip, and the like
  • Various points and means of adjustment can be provided, such as slip-lock buckles and the like to allow the wearer to adjust the fit. It is preferred that the securing means be adjustable such that a snug fit can be obtained, since it is this snugness that substantially prevents movement of the yoke relative to the person.
  • the load strap is configured to receive a load at one end, such as grocery bags and the like, and is configured to be attached to or otherwise supported by the yoke.
  • the yoke is designed to comfortably apply the load, transferred through the tension in the load strap, to the ergonomically correct position on the shoulders.
  • the combination of the load strap and the yoke is also configured to broadly distribute the load to prevent pinching or unreasonable concentration of the load on a narrow part of the shoulder.
  • the load straps be constructed of webbing for its wide distribution of load, however, other tensile members, such as rope, cable, fabric strips and such, can be used.
  • a load strap guide is positioned on at least one of the right shoulder pad and the left shoulder pad and being configured to maintain a desired alignment of the load strap.
  • the load strap is configured to extend from a first side of the person to a second side of the person, extending over at least one of the right shoulder pad and the left shoulder pad, being guided by the load strap guide.
  • the first side of the person can refer to either the anterior or the posterior of the person. Although always opposite to the first side, the second side can also be either the anterior or posterior.
  • the load strap guide can be any number of means that maintain the straps lateral position relative to the yoke, lateral movement being perpendicular to the length of the load strap.
  • the load strap guide can be one of a loop means, a rail means, and a hook-and-loop means.
  • the load strap can be removably attached to the yoke by a removable attachment means, such as a buckle means, a button means, a hook-and-loop means, and a snap means. Movement of the load strap parallel to the length of the strap may be prevented by fastening the load strap to the yoke.
  • a series of eyelets are spaced along the load strap are provided to selectively receive a mating fastener, such as a stud, a button and a hook, which is secured to the yoke.
  • the means for attaching the load to the load strap can be a loop, a hook means, a ring, a D-ring, a carabiner, or any other appropriate means. This means can be found at either the first end of the load strap or both the first and second ends of the load strap.
  • a securing means can be provided to removably affix a loose end of the load strap to the yoke, the securing means can be one of a buckle means, a button means, a hook-and-loop means, and a snap means. This may be provided to prevent a loose or unused load strap from swinging freely.
  • the hook and eyelet embodiment is similar to the cam lock embodiment in that they both permit the lengthwise movement of the load strap to permit the load strap to be lowered such that the load can be engaged with the means for attaching the load without lifting the load from the floor or table.
  • the person can then pull up the load strap to a desired elevated level and lock the load strap into position, using either the eyelets or cam lock. In the elevated position, the load can be guided and controlled more easily with the hands or arms.
  • the cam lock option is preferred due to its simplicity and ease of use.

  • the lifting apparatus 20 is comprised in this embodiment of a yoke 28 worn by a person on the body 22 with a strap or series of straps acting as a securing means 36 to secure the yoke 28 to the person to prevent substantial repositioning of the yoke 28.
  • the yoke 28 has a right shoulder pad 30 and a left shoulder pad 32 with a connecting structure 34 between the two.
  • the yoke is made of two sheets of material with cushioning sewn there between, such as foam, although other construction schemes are also permitted.
  • Attached to the yoke 28 are two load straps, the right load strap 42 and the left load strap 44. There could be any reasonable number of load straps attached to the yoke 28, such as one, two, three, or four load straps. For instance, if four load straps were attached, one possible arrangement is that two load straps could be attached to the anterior 46 side and two more could be attached to the posterior 48 side of the yoke.
  • the right load strap 42 and the left load strap 44 are slidably or adjustably attached to the yoke 28 through use of a fabric loop 58 on each side configured to insertably receive their respective load straps.
  • the loops 58 freely permit the lengthwise movement of the load straps, without permitting the straps to fall off the shoulder or reposition to an undesirable state.
  • the loops are positioned on the posterior 48, although other locations are conceived.
  • the left load strap 44 is inserted through the cam lock buckle 52 on the left side and then through the loop 58 on the left side.
  • the loops 58 and the cam lock buckles 52 act as load strap guides.
  • the cam lock additionally serves to lock the load strap in desired position, for instance when lifting or carrying the load.
  • the hook-and-loop pad 60 On the first end 68 of the load straps, in this embodiment, is a hook-and-loop pad 60, with a corresponding hook-and-loop pad 60 attached to the yoke 28, to permit the removable attachment of the first end 68 to the yoke 28 to prevent swinging of the end when free.
  • the hook-and-loop pair can be formed to connect any portion of the load straps, such as the first end 68 or the second end 70, to any portion of the yoke 28, such as the anterior 46 side or the posterior 48 side.
  • the hook-and-loop 60 is to permit the tucking away of any free ends of the load strap. This tucking away of loose straps is also helpful when donning the apparatus, preventing the hooking of straps by the arms and hands.
  • each carabiner 66 Hung on each carabiner 66 is a load 26, such as a grocery bag. It is often a desire for the person to adjust the height of the hanging load 26 relative to the shoulders, for comfort and control. So, to permit this, the cam lock buckles 52 can be opened to permit the sliding of the load straps, and then closed and locked when the correct hanging height has been obtained. This is especially advantageous when attaching and detaching the load 26.
  • the cam lock buckle 52 when attaching the load 26, the cam lock buckle 52 can be unlocked and the load strap is pulled down by the second end 70, to permit extra length for reaching to and attaching the load.
  • the load strap can be pulled by the first end 68 to lift the load 26 to a manageable height, where it will not excessively swing and can be easily handled and controlled. At this height, or any height for that matter, the cam lock buckle 52 can be again locked.
  • a carabiner 66 and D-ring 64 are shown as means for attaching a load 26, other means can be used, such as a hook or loop at the end of the strap.
  • the securing means 36 there are two straps, a vertical securing strap 38 and a horizontal securing strap 40.
  • the vertical securing strap 38 is attached by one end to the connecting structure 34 of the yoke 28, and by the other to the center of the horizontal securing strap 40.
  • the horizontal securing strap 40 extends across the back and each end under the respective arm of the person to connect ultimately with the yoke 28 on the anterior 46 side. In this arrangement, both arms are completely encircled by the yoke 28 and the straps of the securing means 36, to prevent slippage of the yoke 28 and repositioning.
  • Adjustment means such as slip-lock buckle may be provided to permit adjustment of the vertical securing strap 38 and the horizontal securing strap 40.
  • the horizontal securing strap 40 can connect to the yoke through a side squeeze buckle 72 at each end to permit the quick release and removal of the apparatus 20.
  • the securing means 36 may additionally be constructed integrally to the yoke 28, such as cutting the yoke 28 and securing means 36 from the same material, cloth or similar.
  • the single piece unit would wrap about the body in a similar manner to the described embodiments, connecting and adjusting at appropriate points. Additionally, packs or pockets may be formed on the yoke 28 and/or securing means 36 to store items within the apparatus 20.
  • FIGs. 2A-B an alternate embodiment of the present invention can be seen.
  • This embodiment is similar in many respects to the embodiment of Figs. IA-B, such as the structure and form of the yoke 28 and securing means 36.
  • the difference lies in the load straps 42 and 44 and their connection to the yoke 28.
  • a load 26 at both the first end 68 and the second end 70 of the load straps 42 and 44, shown here as a D-ring 64 and carabiner 66.
  • a load 26 can be hung from both the anterior 46 and posterior 48.
  • the loops 58 allow the substantially free sliding of the load straps relative to the yoke 28.
  • a slip lock buckle 74 can be used for adjusting the load straps.
  • Figs. 3 A-B show yet another alternate embodiment that is similar in some respects to the primary embodiment of Fig. 1.
  • This embodiment has a loop 58 sewn into each of the right shoulder pad 30 and the left shoulder pad 32. with the load straps 42 and 44 inserted there though.
  • Near the first end 68 of the load straps is an aligned series of eyelets 56 that are configured to selectively receive the stud or hook 54 fixed to the yoke 28. In this way, multiple heights can be chosen for the load 26 hanging on the posterior 48.
  • Another preferred embodiment is shown in Figs. 4A-B. Again, this embodiment is very similar to the embodiment illustrated in Figs.
  • the locking cam buckle 52 feature is advantageous because it eliminates the need to create a balanced load situation, where the anterior 46 load must match the weight of the posterior 48 load. Instead, any loading scheme is possible, such as no load on the anterior 46 and a heavy load 26 on the posterior 48 side.
  • the cam lock buckle 53 essentially serves to isolate the tensions created by the anterior 46 load 26 and the posterior 48 load 26 at the lock. Basically, a second load 26 is not required to counterbalance the first load 26.
  • Figs. 5A-B show yet another alternate embodiment of the present invention.
  • the load straps 42 and 44 lying over the shoulder, as is shown in the previous embodiments, they are shown directly sewn to the posterior 48 side of the yoke 28.
  • the load straps are not adjustable relative to the yoke 28, although slip lock buckles may be provided to permit the adjustment of the length of the straps.
