2. Description of Related Art
Military personnel, law enforcement officers, and other workers have traditionally carried most of the essential tools of their trade on their belts. Duty/tool belts, and the weight and shape of the equipment carried on them, not only cause discomfort and fatigue to the wearers wearing them, but over the years of the wearer's career often cause chronic physical problems, including serious back, leg, hip, and nerve ailments.
The duty/tool belt that provides the foundation on which the wearer's tools are supported has traditionally been a heavy, rigid, leather belt, with a large metal buckle. The better leather belts are made of two layers of leather, glued, and stitched tightly together, to increase the belt's stiffness for the purpose of supporting the items it must carry.
In order to provide some support for the weight of the equipment, duty/tool belts are often attached to the wearer's trousers belt beneath it by several “keepers” spaced at intervals around the belt. These keepers are leather or synthetic straps, typically ½″ to ¾″ wide, that are placed around both the duty/tool belt and the trousers belt beneath it, after which the keeper is fastened into a closed loop either with two metal snaps or with Velcro to hold the two belts together and thus restrict the duty/tool belt's movement on the user's waist.
Alternatively, duty/tool belts are sometimes made with hook-and-loop (“Velcro”) material on their underside, to attach them, without keepers, to a trousers belt faced with corresponding Velcro material.
The paramount purpose of the duty/tool belt is, of course, to allow the wearer to carry his or her most important items of equipment in a manner that will make them both secure, and readily accessible when needed.
As an example, a typical police officer's “duty belt,” as it is called, often supports from 10 to as much as 20 pounds or more of equipment, typically including a semi-automatic pistol in a heavily-constructed, rigid duty/tool holster, a magazine pouch with two spare pistol magazines containing 12-18 rounds of ammunition each, one or sometimes two pairs of handcuffs, a radio with batteries, a baton (solid or expandable), a flashlight, pepper spray, rubber gloves in a glove case, and possibly a Taser, spare Taser cartridges, a cell phone, a duty/tool knife with glass breaker and seat-belt cutter, a citation book (at least for the foot patrol wearer), keys, and other items.
The result of having a significant amount of equipment and/or weighty tools suspended or attached to a duty/tool belt is that all of the considerable weight of the duty/tool belt presses downward on the wearer's hips. Depending on the wearer's physique, physical condition, the material and construction of the belt itself, the equipment carried on it, and the nature of the wearer's job description, the heavy duty/tool belt presses down hard on the wearer's hips, and, as it does, it constricts the wearer's lower back and presses on sensitive nerves. Some wearers find their belts constantly sliding downward over their hips, requiring them to tug the belt back up again and again throughout their work day.
Tightening the belt in an attempt to keep it from sliding down increases the discomfort to the wearer's back, hips, and nerves. The tight belt sometimes causes equipment or equipment pouches to bite into the wearer's hip, or to aggravate the nerves running over the hip.
Typically, the military and law enforcement communities place a high value on tradition and radical changes in uniform design are slow in coming. Generally, the sharp, neat appearance of uniformed personnel and officers is of great importance, and even a minor deviation from the unit's or agency's dress code can subject the wearer to reprimand or discipline. In the past, at least some agencies were so insistent on the uniform appearance of their uniformed officers that they went so far as to require all officers to wear their holsters on the same side, regardless of whether the wearer was right-handed or left-handed.
While such an extreme demand for consistency may now be largely a thing of the past, it is evident that any major deviation from a traditional uniformed military, law enforcement, and other appearance, such as wearing externally-visible suspenders, an equipment vest, or a uniform shirt with equipment pouches sewn into it, would be unacceptable to most military, law enforcement, and other agencies, and thus would not offer a practical solution to the duty/tool belt's physical problems for the majority of wearers who suffer—or will sooner or later suffer—from physical problems as a result of wearing a traditional duty/tool belt.
The present invention relates generally to load bearing and/or suspension systems. In particular, the present invention relates to an ergonomic load bearing and/or suspension system.
In order to alleviate the discomfort, fatigue, and chronic physical problems suffered by many military personnel, law enforcement officers, and others as the result of the weight of their equipment laden duty/tool belts pressing on their hips, nerves, and lower backs, the present invention relates to a suspender system that transfers at least some of the duty/tool belt's weight to the wearer's shoulders, relieving weight and pressure on the wearer's lower back and hips.
Load Bearing and/or Suspension System
In various exemplary, non-limiting embodiments, the load bearing and/or suspension system comprises an over-the-shirt system, which incorporates a visible or partially visible suspenders load bearing and/or suspension system. Alternatively, the load bearing and/or suspension system of the present invention comprises an under-the-shirt system, which comprises a non-visible or only minimally visible, non-suspender load bearing and/or suspension systems.
Patrol “Shirt” Embodiment
In various exemplary, non-limiting embodiments, a shirt, or other overgarment, is formed so as to accommodate the load bearing and/or suspension system instead of actually being the load bearing and/or suspension system. The shirt or overgarment provides a more traditional appearance with non-traditional materials and construction. The shirt or other overgarment may also be formed so as to accommodate conventional or concealed soft armor.
In various additional exemplary, non-limiting embodiments, the load bearing and/or suspension system is applied the shirt or overgarment itself and/or to externally worn hard or soft armor.
In various additional exemplary, non-limiting embodiments, the load bearing and/or suspension system is applied external tactical armor/vests.
A typical shirt or other overgarment may be retrofitted to accommodate the load bearing and/or suspension system of the present invention. For example, an existing duty shirt may be modified to include iron-on patches and cut opening. Thus, a wearer may take a current in-use shirt and make a simply alteration to employ this new system.
In certain exemplary, non-limiting embodiments, the system duty shirt may be modified to incorporate longer zipper access to reach in for adjusting the adjustment dial. In certain exemplary, non-limiting embodiments, the shirt or other overgarment may include a substantially flat interior pocket in this opening where a wearer could keep important personal items, such as, for example, identification cards.
It should be appreciated that the shirt or overgarment itself may have ballistic properties.
Vest Embodiment
In certain exemplary, non-limiting embodiments, the overgarment may comprise a vest, either a tactical-type vest or an external vest. The vest may optionally include a zippered front as well as certain side protection and fitted patterning.
Alternatively, the vest may be constructed so as to provide increased flexibility for a custom fit. In still other exemplary, non-limiting embodiments, the vest can combine a zippered front with a degree of modular dexterity.
Adjustment Dial
In various exemplary, non-limiting embodiments, an adjustment dial is positioned within the load bearing and/or suspension system in order to allow the system to be adjusted for each individual wearer. While an adjustment dial may be utilized, any device capable of retracting appropriate section(s) of the load bearing and/or suspension system may be utilized.
The adjustment dial may be manually manipulated to extend or retract portions of the load bearing and/or suspension system. Alternatively, the adjustment dial may allow for auto-retraction and/or tensioning of the components of the load bearing and/or suspension system.
In various exemplary, non-limiting embodiments, the adjustment dial, or other retracting device, is attached or coupled to a suspender-type portion of the load bearing and/or suspension system. Alternatively, the adjustment dial, or other retracting device, maybe attached coupled to a belt portion of the load bearing and/or suspension system.
Duty Trouser
In various exemplary, non-limiting embodiments, improvements are made to a pair of trousers as well. In various exemplary, non-limiting embodiments, the trousers and body a traditional appearance, but allow for improved performance. In other exemplary, non-limiting embodiments, the appearance of the trousers is modified to provide for even better performance.
Duty/Tool Belt
In various exemplary, non-limiting embodiments, improvements are made to a duty/tool belt. While maintaining a relatively traditional appearance, the improved the duty/tool belt is constructed using extremely non-traditional elements and/or components.
In various exemplary, non-limiting embodiments, the duty/tool belt includes an overmolded portion. The overmolded portion may be included along at least an area of the upper and/or lower edge of the belt, in an area proximate the right and left hip bone areas of a wearer.
The duty/tool belt may be constructed so as to include at least some interfacing loops for the harness structure to support the belt. Alternatively, interfacing loops may be appropriately secured around a more traditional duty/tool belt.
Holsters
In various exemplary, non-limiting embodiments, the load bearing and/or suspension system includes a holster or other pouch or carrier. The holster, pouch, or carrier allows for improved positioning, carrying angles, and/or carry heights. In various exemplary, non-limiting embodiments, the holster, pouch, or carrier is able to be attached or coupled to certain elements of the load bearing and/or suspension system of the present invention.
Support Equipment
In various exemplary, non-limiting embodiments, certain methods of attachment are provided for proper utilization of the load bearing and/or suspension system.
Thus, the load bearing and/or suspension system can be a stand-alone system; can be worn over a shirt, a shirt-like overgarment, and/or vest; can be formed as an integral part of a shirt, a shirt-like overgarment, and/or vest; and/or can be part of a combined body armor carrier and load bearing and/or suspension system.
Velcro Strap Adjustable Version.
In various exemplary embodiments, a Velcro adjustable version of the load bearing and/or suspension system is similar to the adjustment dial version, except that instead of the adjustment dial, the system utilizes Velcro-controlled gross adjustments in the nylon straps that pass down from the right and left shoulder harnesses, combined with plastic adjustment buckles that permit the straps to be shortened or lengthened several inches to allow fine adjustments to be made by accessing the strap ends through the slots in the modified uniform shirts.
In various exemplary embodiments, the plastic buckles are quickly detachable by the user, by means of a glove-compatible pinch-to-release design. The simplicity and less mechanical nature of the Velcro strap adjustable system can be more reliable in extended field use and under adverse conditions.
It should be appreciated that with either the adjustment dial or the Velcro adjustment system, the user has the option of determining how much of the duty/tool belt's weight he or she transfers off the hips and waist, and onto the shoulders. Slack in the load bearing and/or suspension system will leave all or almost all of the weight and pressure on the user's hips and waist, while a tight load bearing and/or suspension system can transfer virtually all of the duty/tool belt's weight to the user's shoulders. Individual users may prefer to adjust the ratio based on their own comfort, physical condition, or the nature of activity in which they are engaged. Analogizing the load bearing and/or suspension system to a backpack with shoulder straps and a hip belt, the user may also wish to tighten and loosen the load bearing and/or suspension system from time to time during the day, to give either his shoulders or his hips a rest by temporarily transferring more of the weight to the other part of his body.
While traditional uniform-style shirts can easily and inexpensively be modified to permit the use of the load bearing and/or suspension system, the load bearing and/or suspension system can also be used with unconventional uniform shirts, such as bike patrol shirts and golf-type shirts. Other types of shirts can be modified to permit the use of load bearing and/or suspension system of this design as well.
Accordingly, various exemplary, non-limiting embodiments of this invention separately provide a load bearing and/or suspension system of improved design.

The exemplary, non-limiting embodiments of this invention will be described in detail, with reference to the following figures, wherein like reference numerals refer to like parts throughout the several views, and wherein:
For simplicity and clarification, the design factors and operating principles of the load bearing suspension system according to this invention are explained with reference to various exemplary, non-limiting embodiments of a load bearing suspension system according to this invention. The basic explanation of the design factors and operating principles of the load bearing suspension system is applicable for the understanding, design, implementation, and operation of the load bearing suspension system of this invention.
It should also be appreciated that the “load bearing and/or suspension system”, “suspender”, and “non-suspender” are used for basic explanation and understanding of the operation of the systems, methods, and apparatuses of this invention. Therefore, the “load bearing and/or suspension system”, “suspender”, and “non-suspender” are not to be construed as limiting the systems, methods, and apparatuses of this invention.
Turning now to the drawing Figs.,
Unfortunately, exposed suspenders ofttimes have a sloppy or non-conventional appearance. Exposed suspenders are also troubled by the possibility of their catching on things and thereby entangling the wearer.
For military or law enforcement personnel, exposed suspenders have an inherent risk that an attacker could use the exposed suspenders straps as a means by which to grab and manhandle the wearer during an altercation.
In response to some of these concerns, some of these exposed suspenders were designed to attach to a duty/tool belt with breakaway keepers that unsnapped when a certain amount of force is applied to the keepers. Unfortunately, this can result in the keepers regularly unsnapping during routine use.
In order to overcome these and other disadvantages of known suspender systems, the present invention, as illustrated in
In various exemplary embodiments, the belt 110 is substantially rigid. The belt 110 includes a belt padding element 116 that extends around a lower portion of the belt, at least along a portion of the belt 110 that will be located over a wearer's hips. In various exemplary embodiments, the belt padding element 116 includes a rolled, molded edge of the belt. The belt padding element 116, if included, provides a degree of padding to provide a measure of comfort to the wearer.
The belt 110 also includes belt attachment means 112 that generally extend from or are embedded within the belt 110.
The harness 130 comprises a fabric, webbing, mesh, or reinforced fiber material that is flexible enough to drape over the shoulders of the wearer, and strong enough to support at least a portion of a load while in tension. Each end of the harness 130 terminates in a harness attachment means 132.
The belt attachment means 112 and the harness attachment means 132 include corresponding mating attachment means, such as, for example, amish buttons, male/female snap-release buckles, Velcro or other hook-and-loop fasteners, a corresponding button and buttonhole, mating snaps, hook-and-eye closures, or other fastening means for removably interlacing or attaching the belt attachment means 112 to the harness attachment means 132.
The undergarment 150 may comprise an undershirt, T-shirt, or vest. In various exemplary embodiments, the undergarment 150 may have certain ballistic properties. As illustrated, undergarment 150 is intended to be worn under the harness 130.
The overgarment or shirt 170 is intended to be worn over a predominant portion of the harness 130, but tucked under or into the belt 110 so as to at least partially conceal or hide the harness 130 under the shirt 170. In order for the harness attachment means 132 to be able to engage the belt attachment means 112, one or more apertures 172 are formed through the shirt 170. In various exemplary embodiments, the aperture's 172 are formed proximate the location of the belt attachment means 112. It should be appreciated that the closer the location of the apertures 172 to the belt attachment means 112, the less of the harness 130 that becomes visible outside of the shirt 170.
In various exemplary embodiments, the apertures 172 include grommets, stitching, or other reinforcement around their perimeter.
By incorporating apertures 172 in the shirt 170, when the load bearing and/or suspension system 100 is worn, the belt 110 can be worn in a traditional fashion, over the wearer's pants and shirt 170, while the harness 130 can be worn under the shirt 170. The harness attachment means 132 are able to pass through the apertures 172 in order to connect or attach to the belt attachment means 112.
Thus, the harness 130 is able to be releasably connected or coupled to the belt 110 such that the load of the belt 110 can be shared between the belt 110 and the harness 130, and thus be distributed between the wearer's hips and shoulders.
It should be appreciated that

In various exemplary embodiments, the load bearing and/or suspension system 300 includes a padded harness 330 passing over each of the user's shoulders, similar in design to a handgun shoulder holster harness. A nylon strap with Velcro adjustment, or a circular plastic “X” juncture, connects the two shoulder sections behind the user's neck, between the shoulder blades. Each shoulder section passes over the front and rear of the shoulder, and joins below the user's armpit, where the front and rear straps connect to a nylon pad.
The nylon pad holds a knob-shaped dial-type, adjustment dial 335, by means of which the user can lengthen or shorten a loop of vinyl covered steel wire 333 by turning the adjustment dial 335. Attached to the bottom end of the dial-adjustable portion of cable 333, on the user's right and left sides, are harness attachment means 332 that attach to belt attachment means 312. The harness attachment means 332 on each side passes through the aperture 372 in the shirt 370, to allow the harness attachment means 332 to attached to the belt attachment means 312 and provide support to the belt 310 at a point approximately even with the side-seam of the wearer's uniform trousers.
As illustrated in
