Description
- 1. Field of the Invention
- The invention relates generally to a personal load suspension system, and more particularly to a suspender system configured to bear a load from a tool belt.
- 2. Background Art
- The use of personal suspender systems (“suspenders”) in conjunction with belts and back supports has increased in recent years as employers and tradesmen have realized that such systems help distribute, balance, and secure heavy loads, thereby lessening the incidence and severity of work-related accidents. Often tool belts may be utilized to bear relatively heavy loads, which may include tools, fasteners, and other implements of a user's trade. In addition to the hazard posed by such objects to the user should the belt shift or become unstable, there is also the issue of back strain due to the weight involved, balancing of the load, movement of the user, and a myriad of other factors.
- More recently, belt and back support combinations have become more commonplace, with the back support helping to minimize back injuries and stabilize a wearer, while also more securely supporting the tool belt. Additionally, suspenders are being connected to such systems to help distribute loads from the waist to the shoulders. While these changes represent important steps in the lessening of back-related injuries, traditional combinations of traditional-style suspenders with traditional tool belt systems still leave much to be desired in terms of comfort, flexibility, safety, and effectiveness. For example, traditional suspender configurations may become easily displaced from a desired orientation on a user's shoulder, resulting in possible injury, or damage to the contents of the tool belt. Furthermore, traditional suspender systems have not been well-designed to accommodate the heavier loads and changing job demands that exist in certain labor-intensive trades. Accordingly, a need exists for a load suspension system having increased comfort and flexibility, while maintaining ease of use.
- In one embodiment, a load suspension system is disclosed, having a plurality of straps for operative connecting to a load to be borne by a user. The straps typically will include connection points for operatively connecting to a load, and may also include accessory attachment points for retaining desired accessories. At least one stretch element is incorporated into the load suspension system, to provide a degree of shock absorption to the system. The elasticity of such a stretch element may be limited by a range limiter, comprising a relatively inelastic material, and traversing a stretch element such as to define a maximal stretch length.
- In one embodiment, a method for manufacturing a load suspension system is disclosed, comprising the steps of providing a plurality of straps, operatively connecting such straps via a central section, and incorporating at least one stretch element and at least one pad section into select straps. In one embodiment, the method further comprises operatively connecting reversible attachment points to select straps to reversibly connect to a load.
- Other aspects and advantages of the invention will be apparent from the following description and the appended claims.

FIG. 1 is a front view one embodiment of a load suspension system. -
FIG. 2 shows one embodiment of a load suspension system in use. -
FIG. 3 is a rear view of one embodiment of a load suspension system. -
FIG. 4 is a rear view of one embodiment of a load suspension system in use. -
FIG. 5 is a top view of one embodiment of a load suspension system. - As shown in
FIG. 1 , one embodiment of the invention comprises aload suspension system 1 having a pair offront straps 2, each of which comprises first and second stretch elements 4, and apad section 6 disposed between each of the first and second stretch elements 4. Thepad section 6 is disposed such that it will rest substantially upon a user's shoulder when theload suspension system 1 is worn by the user. Acentral section 8 operatively connects to an upper end of each of thefront straps 2, and is also operatively connected to an upper end of at least onerear strap 3. - The
pad section 6 may comprise any material or combination thereof known in the art to provide comfort to a user in a load-bearing application. In one embodiment, thepad section 6 comprises a resilient foam selected to provide a desired degree of comfort and durability. In one embodiment, the resilient foam of thepad section 6 is encased in a fabric, to advantageously protect the foam and to maintain a desired shape of thepad section 6. In one embodiment, when a fabric is used with the foam, the fabric will operatively connect to one or more adjoining components of the load suspension system, thereby maintaining the position of the foam relative to such components. In one embodiment, the fabric is breathable, to better permit passage of air into and through thepad section 6, advantageously providing ventilation to a user's shoulder beneath thepad section 6, and/or more effective evaporation of sweat or other moisture that may permeate thepad section 6. - In one embodiment, the
pad section 6 comprises a gel component. The gel component may be of any type known in the art. In one embodiment, the gel component comprises adiscreet gel insert 7 disposed in a predetermined location within thepad section 6. In one embodiment, thepad 6 section is configured to be relatively inelastic relative to the elasticity of the stretch elements 4. - Various configurations described herein advantageously provide shock-absorption with respect to a suspended load operatively connected to the
load suspension system 1, while maintaining stability of the load on a user's shoulders by minimizing displacement of thepad section 6. Typical loads include, but are not limited to, tool belts, tools, and tool pouches. - Stretch elements 4 may comprise any material or combination of materials known in the art. In one embodiment, a stretch element 4 may comprise multiple subcomponents, each having similar or varying degrees of elasticity, to provide a desired balance of elasticity and support to the
load suspension system 1. In such an embodiment, the stretch element 4 may comprise a central elastic element and a peripheral elastic element. In one embodiment, abinding component 9 may operatively connect along a periphery of multiple components to provide reinforcement of the operative connections therebetween. Thebinding component 9 may also function as a peripheral elastic element, as described above with respect to the stretch elements 4. - In one embodiment, a relatively short length of binding
component 9 is operatively connected to a relatively longer periphery of various other components, thereby achieving a desired curvature in such components. For example, in such a configuration where a length of webbing is bunched along its periphery and stitched to a shorter length of bindingcomponent 9, the result will be a rippling or folding effect on the webbing, causing it to bunch along its periphery, thereby forming a concave cross-section in the webbing. Thebinding component 9 may comprise, but is not limited to, binding tape. Such a configuration advantageously imparts a curvature to the webbing, which may more comfortably conform to the contours of a user's body. - In one embodiment, the
load suspension system 1 includes at least one reinforcingelement 12 disposed substantially parallel to the longitudinal axis of thepad section 6. The reinforcingelement 12 will operatively connect to a first location on thefront strap 2, above thepad section 6, and to a second location on thefront strap 2, below thepad section 6. The reinforcingelement 12 may pass through thepad section 6, or along any outer surface thereof. The reinforcingelement 12 may also operatively connect to one or more locations along the length of thepad section 6. In one embodiment, the reinforcing element operatively connects to a resilient foam and/or a gel insert disposed in thepad section 6. A reinforcingelement 12 advantageously provides a redundant connection should a load-bearing component of thepad section 6 fail, due to e.g., heavy loads, or wear. A reinforcingelement 12 may also advantageously limit any elasticity of thepad section 6. - In one embodiment, the
load suspension system 1 includes at least one stabilizingelement 14 configured to reversibly connect each of the pair offront straps 2. Typically, any such stabilizingelement 14 will be disposed such that it may traverse a front surface of a user's body when theload suspension system 1 is in use. The stabilizingelement 14 will typically comprise two strap segments reversibly connectable via abuckle 16 or similar component. The stabilizingelement 14 may also have an adjustable length, permitting adjustment of fit to a user's size and comfort. Such a configuration advantageously provides an increased stability and/or customized fit to theload suspension system 1. - In one embodiment, each
front strap 2 includes at least onerange limiter 10 oriented substantially parallel to the longitudinal axis of the operatively connectedfront strap 2, and traversing at least one stretch element 4. Typically, therange limiter 10 will be operatively connected to theload suspension system 1 such that therange limiter 10 will have a predetermined amount of slack along at least a portion of its length when one or more underlying stretch elements 4 are in an un-stretched configuration. Eachrange limiter 10 will have a limited elasticity, typically substantially below that of the stretch element 4, such that therange limiter 10 will define a maximum stretch range of the stretch element 4. Eachrange limiter 10 will operatively connect to afront strap 2 at locations above and below its associated stretch element 4. - In one embodiment, the
range limiter 10 may have an adjustable length, or may be attachable at multiple locations along the length of thefront strap 2, so as to provide a user-selectable maximum stretch range for the operatively connected stretch element 4.Range limiter 10 configurations may include hook-and-loop components, or any other components known in that art to permit user adjustment of length and/or connection point. In one embodiment, therange limiter 10 is operatively connected directly to, or continuous with, a reinforcingelement 12 traversing thepad section 6. - As shown in the embodiment of
FIG. 2 , in use, upper ends of thefront straps 2 will extend over a user's shoulders to meet at an operatively connected central section 8 (not visible inFIG. 2 ), typically disposed behind a user's neck and/or adjacent an upper portion of a user's back.Pad sections 6 rest atop the user's shoulders, and a stabilizingelement 14, if present, will typically be disposed across a user's chest. A lower end of eachfront strap 2 will typically include areversible connector 18 for operatively connecting to a load such as atool belt 20. Eachfront strap 2 may also include anadjuster 22 slideably disposed along a length of thefront strap 2. Theadjuster 22 may be of any type known in the art, including, but not limited to, a slide buckle. Theadjuster 22 advantageously allows a user to adjust the length of thefront strap 2 for increased comfort, improved fit, and/or to adjust for varying loads on theload suspension system 1. - In one embodiment, one or more
accessory fasteners 24 may be operatively connected at one or more locations on theload suspension system 1. Anaccessory fastener 24 may comprise a webbing loop, pouch, snap-hook, or any other element known in the art for retaining a desired accessory. - As shown in
FIG. 3 , one embodiment of theload suspension system 1 comprises at least onerear strap 3. A single rear strap configuration (not shown) will typically include a single strap operatively connected to a location on thecentral section 8 furthest from the operative connection points of thefront straps 2, such that it will be substantially centered on a user's back when worn. - In an alternative embodiment, a pair or any plurality of
rear straps 3 are operatively connected to thecentral section 8. In one embodiment, a pair ofrear straps 3, comprise a continuation of thefront straps 2 configured to pass through thecentral section 8. - One or
more adjusters 22 may be disposed on each of the rear straps 3. Each of therear straps 3 will typically terminate in an operative connection to areversible connector 18 for operatively connecting to a load, such as a tool belt, tool pouch, and/or any other type of belt or apparel known in the art. - In one embodiment, a retaining
loop 26, or similar connector may be disposed at a central location of thecentral section 8. Such a retainingloop 26 advantageously provides a centralized attachment point for easily storing theload suspension system 1 in a storage location. In one embodiment, the retainingloop 26 andsuspension system 1 may be configured to provide a predetermined degree of fall protection to a user. For example, a line may be connected to the retainingloop 26 to help stabilize the user when used in an environment with hazardous footing. However, the use of theload suspension system 1 as a fall protection device may require additional components, beyond the current scope of the instant application. - As shown in the embodiment of
FIG. 4 , the load suspension system will typically be worn such that thepad sections 6 rest upon a user's shoulders, and thecentral section 8, is disposed behind the user's neck, typically over the midline of the user's back. In one embodiment, thecentral section 8 will include agel component 28. Thegel component 28 advantageously provides additional cushioning, resulting in increased comfort to the user.Reversible connectors 18 operatively connected to therear straps 3 are reversibly connectable to a load at one or more locations along the user's back and/or sides. - As shown in
FIG. 5 , in one embodiment, each of thefront straps 2 will have a curved configuration. Such curvature will typically be defined by a greater angle relative to a centerline C nearer thecentral section 8, and a lesser angle relative to a centerline C as thefront strap 2 extends away from thecentral section 8. A curved configuration of thefront strap 2 advantageously provides increased comfort to a user by providing sufficient clearance for neck movement, yet providing a substantially vertical orientation at its distal end (when worn) to operatively connect a load to be suspended by theload suspension system 1. For purposes of describing the angle of curvature, the term “centerline” means an imaginary line bisecting thecentral section 8 and passing between thefront straps 2, in the same plane, and equidistant to each. In one embodiment, each of thefront straps 2 will be configured to curve both inwardly and outwardly, along their length, relative to thecentral section 8. - The various components of the
load suspension system 1 may comprise any material or combination thereof known in the art. In one embodiment, the components will include elastic and relatively inelastic webbing. The various components of embodiments of the invention may comprise any shape and/or size that does not render such embodiments non-functional in the manner described. For example, in one embodiment, thecentral section 8 will comprise an ovoid shape. In one embodiment, construction and assembly of theload suspension system 1 comprises the stitching of the various components to other operatively connected components in a predetermined manner. Construction and assembly techniques may comprise any such techniques known in the art. - In one embodiment, any combination of a
front strap 2,rear strap 3,range limiter 10 and reinforcingelement 12, may be formed of a single continuous element, typically a fabric webbing. The continuous element may pass through, under, or over an operatively connectedcentral section 8, and/orpad section 6. In one embodiment, a plurality offront straps 2 and/or a plurality ofrear straps 3, may each comprise a single continuous element. Typically, such a continuous element will operative connect at a non-midpoint location thereof to thecentral section 8 of theload suspension system 1. Stretch elements 4, and associated components such asrange limiters 10, may also be disposed along one or morerear straps 3. - As used herein, references to “front” strap and “rear” strap are relative to the
central section 8. For example, a portion of afront strap 2 may extend over a user's shoulder to operatively connect to acentral section 8 disposed on the user's back. Accordingly, the terms “front” and “rear” when referring to a component of theload suspension system 1 are terms of convenience and differentiation, and should not be construed as locational limitations relative to a user's body. Similarly, the terms “upper” and “lower” when referring to a strap or similar component, are terms of relational convenience, typically referencing elements that are proximal to (upper) and distal from (lower) acentral section 8. - While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the invention should be limited only by the attached claims.
