Description

FIELD OF THE INVENTION

The present invention relates to systems and methods for manually supporting and transporting loads. More particularly, the present invention relates to load bearing garments and associated garment systems for supporting and transporting weighted articles or loads, and protecting a wearer from the environment.

BACKGROUND OF THE INVENTION

The need or desire to manually carry items from one point to another, remains, for most, an often encountered issue. Although the size and weight of a number of electronic devices, such as notebook computers and PDAs, have been reduced, manually transporting such devices still remains an issue for many.

As is well known, briefcases are often employed to manually transport articles from one point to another. Briefcases can, however, be very expensive and, in many instances, too bulky for everyday use.

On a smooth, even surface, such as an airport terminal, wheeled bags or carrying cases can also be used to transport articles (or loads). On uneven terrain, however, wheeled bags are difficult to maneuver and, in many instances, ineffective.

A further drawback and disadvantage of briefcases and wheeled bags is that such carrying devices must be carried or pulled by hand.

Various apparatus and garments have thus been employed to manually support and transport weighted articles, while not detracting from the freedom of hand and arm movement. The apparatus and garments include, for example, utility vests, backpacks and wearable garments, such a jacket.

As is well known in the art, the primary objective of most wearable garments, such as a jacket or vest, is to provide protection from the environment for the user or wearer. The wearable garments do, however, typically include one or more packets for carrying miscellaneous items. The size and load bearing capacity of the pockets are, unfortunately, quite limited.

Backpacks also have several drawbacks and disadvantages. A major disadvantage with all backpacks is that, the backpacks provide minimal, if any, protection from the environment when worn. Thus in inclement weather, e.g., cold or wet, a coat or jacket is typically required to provide protection from the environment.

Further, it is very difficult, if not impossible, to control the load placement and distribution with most commercially available backpacks; particularly, the larger capacity backpacks. Moreover, some users also have a tendency to throw their backpack over one shoulder, which can, and in many instances will, result in orthopedic and muscle pain and injury.

Additionally, when standing still, the static force exerted by the backpack (and load therein) on the body is simply equal to the weight of the backpack and its contents. However, peak forces exerted on the body can increase dramatically to as much as 2-fold greater than the static force when one starts to walk or run while wearing the backpack. This increase is due to the requisite alternate deceleration and reacceleration of the load, which must track the vertical movement of the hips on every step. These high, and sometimes jarring, peak forces are transferred to the joints and connecting musculature, resulting in orthopedic and muscle pain and injury.

It would thus be desirable to provide wearable garments and associated garment systems that are adapted to effectively support and transport loads, and protect a wearer from the environment.

It is therefore an object of the present invention to provide ergonomic load bearing wearable garments and associated garment systems that are adapted to support and transport loads, and provide protection from the environment, while not detracting from the freedom of hand and arm movement.

It is another object of the present invention to provide ergonomic load bearing and energy absorbing wearable garments and associated garment systems that are adapted to support and transport loads, and provide protection from the environment, while not detracting from the freedom of hand and arm movement.

SUMMARY OF THE INVENTION

The present invention is directed to ergonomic load bearing wearable garments and associated garment systems that are adapted to support and transport loads, and provide protection from the environment, while not detracting from the freedom of hand and arm movement. In some embodiments of the invention, the wearable garments also include means for dissipating energy or load peaks.

In one embodiment of the invention, the load bearing wearable garments generally comprise a garment adapted and configured to cover at least a portion of a user's upper torso, the garment including at least one rear pocket adapted to receive at least one article therein, and an integral load bearing system adapted to support weighted articles contained in said pocket and redistribute forces resulting therefrom.

In some embodiments, the load bearing system includes at least first and second cooperating pairs of internal straps.

In some embodiments, the load bearing system includes first and second internal straps.

In some embodiments, the load bearing system includes energy absorbing means for reducing peak forces transferred to said user's body.

As will readily be appreciated by one having ordinary skill in the art, the ergonomic load bearing wearable garments and associated garment systems of the invention provide numerous advantages compared to prior art methods and systems for manually supporting and transporting weighted articles (or loads). Among the advantages are the following:

• • The provision of ergonomic load bearing wearable garments and associated garment systems that significantly enhance the load bearing capability of the wearable garments.
  • The provision of ergonomic load bearing wearable garments and associated garment systems that provide protection from the environment.
  • The provision of ergonomic load bearing wearable garments and associated garment systems that facilitate proper anatomical distribution of exerted forces resulting from weighted article(s) disposed in or on the garments.
  • The provision of ergonomic load bearing wearable garments and associated garment systems that facilitate proper posture by a user.
  • The provision of ergonomic load bearing wearable garments and associated garment systems that include energy absorbing means that reduces peak forces transferred to the body.
  • The provision of ergonomic load bearing wearable garments and associated garment systems that substantially reduce the risk of orthopedic and muscle pain and injury from forces exerted on the body by weighted article(s) carried in or on the garments.

In some embodiments, the wearable garments include an inner liner, which similarly can be constructed of various conventional materials/fabrics and combinations thereof, such as wool, Polyester®, Acrylic®, cotton, Nylon®, silk, etc.

As will readily be appreciated by one having ordinary skill in the art, the wearable garments of the invention can thus be constructed to provide optimum comfort and protection from the environment.

The ergonomic reinforced or load bearing wearable garments and associated garment systems of the invention will now be described in detail. Since the load bearing and energy absorbing systems of the invention can be employed with any of the aforementioned wearable garments, in the interest of brevity and minimization of any risk of obscuring the features and concepts of the invention, the load bearing wearable garments and associated garment systems of the invention will be illustrated and described in connection with only one wearable garment, the vest (or iVest™) shown in FIGS. 1-3.

Referring now to FIGS. 9-12, there is shown one embodiment of a load bearing garment of the invention. Referring first to FIGS. 9 and 10A, the illustrated load bearing system includes a pair of front 40 and a pair of rear 42 straps having strap engagement means disposed on the ends 41, 43 thereof.

In a preferred embodiment of the invention, the front 40 and rear 42 straps can comprise various widths and thickness; provided, each strap 40, 42 has a tensile or yield strength of at least 20 MPa. The straps 40, 42 can thus be constructed of various conventional fabric materials, such as Nylon®, fiber reinforced cloths, etc. In a preferred embodiment, the straps 40, 42 are constructed of Nylon®.

According to the invention, the front straps 40 are securely engaged to the interior surface of the front panel 12 by conventional means. In some embodiments, the first (or top) ends 45 of each strap 40 is sewn or stitched to the interior surface of the front panel 12 (see FIG. 10A).

Referring to FIG. 10B, in some embodiment of the invention, the interior surface of the front panel 12 includes strap adjustment means for adjusting the horizontal placement of the first ends 45 of the front straps 40. In some embodiments, the adjustment means comprises a plurality of female snaps 48 of a snap system (that are disposed in desired horizontal positions), which are adapted to receive a male snap 49 disposed on each end 45 of the front straps 40.

In a preferred embodiment, the rear straps 42 are similarly securely engaged to the interior surface of the rear panel 16 by conventional means. In some embodiments, the first ends of the straps 47 are also sewn or stitched to the interior surface of the rear panel 16 (see FIG. 9).

In a preferred embodiment, the straps 40, 42 include strap engagement means adapted to removably secure the second or loose ends 41, 43 of straps 40, 42. According to the invention, various conventional strap engagement means can be employed within the scope of the invention to facilitate secure, yet removable, engagement of straps 40, 42.

In a preferred embodiment, the strap engagement means comprises an adjustable male/female clip assembly, such as the clip assembly 50 shown in FIG. 11. As illustrated in FIG. 11, the clip assembly 50 includes a male end 52 that is adjustably engaged to one end of a strap, in this instance ends 43 of rear straps 42. The clip assembly 50 further includes a female end 54 that is securely engaged to one end of the mating strap, in this instance ends 41 front straps 40.

As is well known in the art, the female end 54 of the assembly 50 is designed and adapted to receive the male end 52 therein, whereby the male end 52 and, hence, strap 42 engaged thereto, are removably secured to the female end 54 and, hence, strap 40 engaged thereto (see FIG. 12).

Referring now to FIGS. 13-16, there are shown additional embodiments of load bearing garments of the invention. Referring first to FIGS. 13 and 14, the load bearing system in this embodiment includes continuous straps; preferably, right and left continuous straps 60, 62.

In some embodiments of the invention, the straps 60, 62 are stitched to the interior surface of the front and rear garment panels 12, 16 (as shown in FIGS. 13 and 14). In some embodiments, the stitching is continuous, i.e. extends from the front 12 to rear panel 16.

Referring now to FIGS. 15 and 16, in the illustrated embodiment, the garment 10a includes left and right reinforced strap pockets (or guides) 68a, 68b. According to the invention, each pocket 68a, 68b is sized and positioned to receive a respective one of the straps 60, 62 therein and guide the strap (i.e. 60 or 62) therethrough.

According to the invention, each strap also includes conventional strap engagement means to secure the first end of each strap 60, 62 to the opposite end thereof. In a preferred embodiment, each strap 60, 62 similarly includes the adjustable male/female clip assembly 50 shown in FIG. 11.

As illustrated in FIGS. 13 and 15, in some embodiments, the female end 54 of the clip assembly 50 is securely engaged to a first end 64 of each strap 60, 62. As illustrated in FIGS. 15 and 16, the male end 52 of the assembly 50 is adjustably secured to the second or opposite end 66 of each strap 60, 62.

Referring now to FIGS. 17 and 18, when the load bearing garments of the invention are appropriately adjusted and worn by the user 100, the engaged straps 40, 42 and 60, 62 are preferably disposed under the arm proximate the juncture of the arm and chest (i.e. arm pit) of the user, whereby any load exerted by an article or articles in the pocket 18 is supported and appropriately positioned by the engaged straps 40, 42 and 60, 62. According to the invention, the engaged straps 40, 42 and 60, 62 can support in the range of 20-80% of the load exerted by an article or articles in the pocket 18 (and/or pocket 24 and/or any additional pocket), depending on the adjustment of the straps 40, 42 or 60, 62. Thus, a balanced load bearing garment, i.e., 50% of the exerted load borne by the load bearing system, 50% of the exerted load borne by the garment, can be readily achieved by virtue of the load bearing systems of the invention.

As will be appreciated by one having ordinary skill in the art, the load bearing wearable garments and associated garment systems of the invention thus significantly enhance the load bearing capability of the wearable garments. The load bearing garment systems also facilitate proper anatomical distribution of exerted forces resulting from weighted article(s) in the rear pocket(s) and thereby proper/desired posture by a user.

In some embodiments of the invention, the load bearing garment systems of the invention also include energy absorbing means. As stated above, when standing still, the static force exerted on the body by weighted article(s) in the rear pocket(s) is simply equal to the weight of the garment and the pocket contents. However, peak forces exerted on the body can increase dramatically to as much as 2-fold greater than the static force when one starts to walk or run while wearing the garment. These high, and sometimes jarring, peak forces are transferred to the joints and connecting musculature, and can result in orthopedic and muscle pain and injury.

To substantially reduce or alleviate such peak forces, in some embodiments of the invention, at least one pair of the paired straps 40, 42 includes a compliant section that is adapted to absorb and, hence, reduce the peak forces transferred to the body. In some embodiments, each of the front straps 40 includes compliant section.

Referring now to FIG. 19, in some embodiments, each strap 40 comprises a two piece strap, having a first section 70 comprising one of the aforementioned fabric materials and a second section 72 comprising a compliant material. According to the invention, the compliant material can comprise various compliant (or stretchable) materials, such as Neoprene®.

In further envisioned embodiments of the invention, each strap 40 comprises a compliant material, whereby the entire strap 40 is compliant.

In yet another envisioned embodiment, each of the continuous straps 60, 62 comprises a two-piece strap; a first section comprising one of the aforementioned fabric materials, and a second section comprising a compliant material.

As will readily be appreciated by one having ordinary skill in the art, the ergonomic load bearing wearable garments and associated garment systems of the invention provide numerous advantages compared to prior art methods and systems for manually supporting and transporting weighted articles (or loads). Among the advantages are the following:

• • The provision of ergonomic load bearing wearable garments and associated garment systems that significantly enhance the load bearing capability of the wearable garments.
