SELF-ADJUSTING SYSTEM FOR JOINT PROTECTION
A self-adjusting system for joint protection comprising a joint protector pad aligned relative to a joint and disposable between an operative orientation and a spaced orientation in relation thereto. A first attachment assembly of at least one elongate strap connects the joint protector to a foot or hand of the wearer, and a second attachment assembly of an elongate strap(s) connecting the joint protector to a point near the torso of the wearer, such as a waistband or belt. In a spaced orientation when the joint is straight, the joint protector is spaced apart from the joint so as not to impede movement. In an operative orientation when the joint is flexed, the joint protector at least partially covers the joint, supporting and protecting it from the underlying surface. The strap(s) ensure the joint protector is automatically properly aligned in moving between the spaced and operative orientation.
1. Field of the Invention
The present invention relates generally to pads, and more specifically, to pads for covering joint(s) such as knee pads or elbow pads, to protect and cushion the same.
2. Description of the Related Art
Pads have been used for decades to cushion the joint of a wearer, such as a knee or elbow on which pressure may be placed during certain activities. For instance, knee pads are commonly used in construction and gardening, and other activities involving kneeling for a prolonged period of time, to reduce pain and alleviate pressure applied to the joint that could otherwise damage the joint. Knee and elbow pads also are employed during sporting activities, such as cycling and skating, to protect the joints from cuts, abrasions, and impact damage that often accompanies sports in which the joints may be scraped, bumped, or take the brunt of a fall. They often protect not just the skin, but the bone, cartilage, and ligaments of the joint as well.
For all their virtues, joint pads still suffer from some major drawbacks. Most joint pads have straps that wrap around the limb of a wearer, such as a leg in the case of a knee pad, to secure the pad in position relative to the protected joint. There are often straps on both sides of the joint, so that the pad does not drift from position during movement. To ensure the pad remains in position, however, these straps are often pulled tightly around the leg or arm of the wearer. This is not only uncomfortable for the wearer, pinching and squeezing the thigh, calf, or arm, but in extreme cases may impede circulation through the limb and affect dexterity. Moreover, straps wrapped around the leg or arm of the wearer will often rub against the skin, irritating and chafing the skin of the wearer the longer the pad is employed. Such irritation occurs whether the pad and straps are applied directly to the skin or over clothing. This irritation is often worse along compressed areas, such as the back of the knee or inner arm, since these areas are subject to increased pressure, higher temperatures, and perspiration during use, such as when the joint is flexed, which only aggravates the irritation. In extreme cases, the irritation and chafing may lead to blistering and even bleeding.
These disadvantages are compounded over time, such that while brief use may be tolerable, longer use such as for hours or even days, can have a debilitating effect and may not be tolerable at all. Indeed, the discomfort from irritation and chafing over prolonged use of a joint pad may eclipse the pain or pressure to the joint without the use of the pad, and some users will forgo use of a joint pad after a time as a result of these debilitating side effects.
Other known joint protection pads clip to clothing to secure the pad in place. These too, however, often wrap around and/or squeeze the attendant limb, thereby suffering the same drawbacks as discussed above. Moreover, the clips are subject to easily disengage when the pad is hit or impacted, and so are not effective in keeping the pad in position to properly cover and protect the joint.
Regardless of how joint protector pads are secured to a wearer, they all shift out of position over time during use, and must be repositioned. This often involves manually moving, shifting, or repositioning the pad and/or straps to return them to their original position. Such repositioning therefore requires the wearer to stop what they are doing to see to the pad and straps, interrupting their activity. Moreover, a shifted pad and/or strap distracts the wearer from their activity until repositioned, which can be significant amount of time until it is convenient to take a break. In some instances, such as in war or on patrol, waiting for a convenient time is not an option, nor is distraction.
It is therefore evident that a better form of joint protector pad is needed to properly protect the joint of a wearer without causing damage or irritation to the wearer. A pad that can be worn for long periods of time would also be beneficial, as would a pad that does not need to be repositioned periodically.
SUMMARY OF THE INVENTIONThe present invention is directed to a system for protecting a joint of a wearer, such as a hinge joint of a knee or elbow. The system provides a joint protector pad to protect, cushion, and/or support a joint in an operative orientation, when the joint is flexed or bent. In a spaced orientation, when the joint is straight, the joint protecting pad is spaced apart or free-floating from the joint, not attached or secured to the limb of the wearer. Rather than having straps that wrap around the leg or arm, the present system includes a set of straps that extend outwardly from the joint protector pad in opposite directions and attach to the wearer at the foot or arm, in one direction, and the torso in the opposite direction.
The joint protector pad is therefore always properly aligned so that when the joint is flexed, the protector pad goes directly into contact with the joint automatically. When the joint is straightened, the straps automatically pull the joint protector pad back into spaced aligned relation to the joint, without any need to manually manipulate the pad or straps. Accordingly, the joint protector pad is always ready and in proper alignment for protecting the joint, and yet is not inhibiting to the joint. The present system eliminates the need for strangulating straps to keep the joint in place, freeing the joint for increased movement without sacrificing protection, and saving the surrounding skin and tissue from irritation and damage. It is also self-adjusting, abolishing the need to manually reposition the pad or straps.
Specifically, the system includes a joint protector aligned with a joint to protect the same. The joint protector may be any type of protection or pad, and may include impact resistant material or frictional material on the outer surface, and cushioning material on the inner surface. A first attachment assembly including one or more straps extends from the joint protector to the extremity, such as a foot or hand, and attaches thereto, such as by loop and/or clips or other attachment member(s). A second attachment assembly includes one or more straps extending from an opposite side of the joint protector, securing at the torso of the wearer, such as at the waistband or belt loops. In at least one embodiment, the straps of the attachment assemblies are slightly elastic, such that they are taut even in the spaced orientation, but remain capable of stretching, such as in the operative orientation. Each strap is also adjustable to accommodate any size or height of the wearer.
These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.
For a fuller understanding of the nature of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:
Like reference numerals refer to like parts throughout the several views of the drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTThe present invention is directed to a system for protecting a joint of a wearer, such as a hinge joint of a knee or elbow. The system may be employed by a person during any activity in which joint protection is desired, or when potential damage to the joint from impact or pressure may occur. Examples include, but are not limited to: construction such as welding, roofing, and floor work; gardening; sports, such as skateboarding, cycling, and skiing; and military activities including patrols, transport, missions, operations, enemy engagement, and even battle.
The present system aligns a joint protector pad with the joint to be protected in a free-floating, uninhibited manner, such that the wearer has the same freedom of motion he or she would have were they not wearing the joint protector system. The limbs of the wearer are not squeezed, pinched, or constrained in any way. When the need arises to kneel or land on a knee or elbow, for example, the joint is flexed. As the joint flexes, and in the same amount of time it takes to perform this action, the system moves into an operative orientation to automatically position the joint protector to cover and protect the joint, without manual manipulation on the part of the wearer. As soon as the joint is straightened or extended, the joint protector pulls away from the joint and into a spaced orientation, once again not impeding limb movement, and is automatically aligned in spaced apart relation with the joint as before and without manual manipulation. Accordingly, the present system is a “self-adjusting” system.
Specifically, and as shown throughout the Figures, the present invention is a system 100 for protecting the joint of a wearer. Any joint may be protected by the present system, but in at least one embodiment the system is particularly useful in protecting joints, such as the knee or elbow, which flex by bending in one direction. To provide context to the invention, and for illustrative purposes only,
As shown throughout the Figures, the system 100 includes at least one joint protector 110, structured to accommodate a joint which it is to protect. For instance, the joint protector 110 may be any size or shape appropriate to receive, fit, cover and/or conform to the shape of various joints, such as knee or elbow. In a preferred embodiment, the joint protector 110 is a pad or other similar structure, and may be multi-use or for a dedicated purpose. One embodiment of a joint protector is shown in
In at least one embodiment, the joint protector 110 also includes an impact resistant portion(s) 112 disposed on an outer surface thereof, as shown in
In at least one embodiment, the joint protector 110 includes at least one cushioning portion 114 (not shown) disposed on an inner surface of the joint protector 110. The cushioning portion(s) 114 is structured to support the joint in a flexed position and to provide relief from pressure applied to the joint. For example, the cushioning portion(s) 114 can be particularly useful to provide a measure of comfort to the wearer when employing the system 100 over an extended or prolonged period of time, such as when kneeling for hours while gardening or laying down flooring. Accordingly, the cushioning portion(s) 114 is made of any material suitable for absorbing pressure, such as pliable, resilient, and/or conforming material, and may be soft to the touch as well. Non-limiting examples include gels, foams, batting, microbeads, cloth, etc. or combinations thereof.
In some embodiments, the joint protector 110 also includes at least one frictional portion 116 disposed on a surface of the joint protector 110, and are structured to increase friction between the joint protector 110 and a supporting surface 10 or joint of the wearer. For instance, as shown in
The joint protector 110 is disposable in aligned relation to the joint 12. When the joint 12 is fully extended, as in a spaced orientation depicted in
The system 100 of the present invention also includes a first attachment assembly 120 connected to one side of the joint protector 110, and a second attachment assembly 130 connected to a different, preferably opposite side of the joint protector 110, as shown throughout the Figures. More in particular, the first attachment assembly 120 comprises at least one strap 122 connecting to the joint protector 110 at its proximal end 124. As depicted in the embodiment of
As noted previously, the first attachment assembly 120 includes at least one strap 122. In some embodiments, as in
The first attachment assembly 120 secures at the distal end 126 directly to the body of the wearer, such as feet or hands, or may secure to items of apparel such as clothing, boots, gloves, sleeves, pants, or other item being worn by the wearer at a position that is disposed at, near, or in the close vicinity of the limb extremity of the wearer. For example, in at least one embodiment the distal end 126 of the first attachment assembly 120 is structured and disposable in at least partially surrounding or encircling relation to a limb extremity, such as a foot or hand, or portion thereof. By way of example,
In some embodiments, such as shown in
Similarly, the second attachment assembly 130 comprises at least one strap 132 and connects to the joint protector 110 at a proximal end 134. In at least one embodiment, the second attachment assembly 130 includes a plurality of straps 132. For instance, in the embodiment of
The second attachment assembly 130, and strap(s) 132 thereof, extend from their attachment at the proximal end 134 at the joint protector 110 to a distal end 136 which is securable at or near the torso of the wearer. As used herein, torso refers to the trunk of a subject, which excludes the arms, legs, and head, and is also not part of the claimed invention. Accordingly, in at least one embodiment the second attachment assembly 130 secures to the waist of the wearer, such as depicted in
The second attachment assembly 130 may also include at least one attachment member 128, as previously described, disposed at a distal end 136 of each strap(s) 132 to secure the strap(s) 132 directly to the body of the wearer, or to items of apparel such as clothing, shirts, pants, waistband, belt loop, belt, jacket or other item being worn by the wearer at a position that is disposed at, near, or in the vicinity the torso of the wearer. By way of example,
As is evident from the Figures, the straps 122, 132 are elongate so as to extend from the joint protector 110 to the distal end 126, 136 located at a foot, hand, or torso of the wearer, respectively. Moreover, the straps 122, 132 do not wrap around and tighten down onto a limb of the wearer, such as a leg or arm, as straps in currently known knee and elbow pads do. Accordingly, because the straps 122, 132 follow along one face or side of a limb (as shown in
In addition, in at least one embodiment the straps 122, 132 are made of an at least partially elastic material capable of slight stretching. Accordingly, when the system 100 is disposed in a spaced orientation, as shown in
Moreover, the straps 122, 132 are also sufficiently resilient such that as soon as the impacting force is no longer applied, the straps 122, 132 quickly return to their original position, along with the attached joint protector 110. Similarly, the resilient characteristic of the straps 122, 132 enable them and the connected joint protector 110 to automatically fall back into aligned relation to the joint when moving between an operative and spaced orientation, and vice versa. Accordingly, the straps 122, 132 may be of any material suitable for providing taut, accurate positioning yet flexibility and resiliency. Examples include, but are not limited to, textiles, woven textiles, natural or synthetic materials, blends, elastics, rubber, polymer-based materials, bungee type materials, and combinations thereof, and may be fortified with chemical or material agents such as to increase strength, resiliency, elasticity, resistance to the elements such as water, etc. Due in part to the elasticity and resiliency of the straps 122, 132 and the positioning and connection of the straps 122, 132 with the joint protector 110 and attachment to the wearer, the present system 100 is referred to as a “self-adjusting” system, requiring no manual manipulation or adjustment once it is initially placed and attached to the wearer.
Moreover, each of the straps 122, 132 is adjustable in length independently of the other straps 122, 132 so as to accommodate any of a range of sizes of a wearer. For example, the straps 122, 132 are adjustable so that the system 100 may be used by a person of any height, including short people (such as under five feet tall) and tall people (such as over six feet tall). The system 100 may also be used by children or adults. The length of each strap 122, 132 may be adjusted by sliding, Velcro®, hooks, buttons, snaps, tying, and any other suitable means of lengthening or shortening. The straps 122 are also separately adjustable from the straps 132, to accommodate for varying lengths of limbs in a wearer.
In at least one embodiment, the system 100 also includes a limb protector disposed adjacent to the joint protector 110 and disposable in aligned relation to at least a portion of a limb of the wearer, so as to protect the portion of the limb in a manner similar to the joint protector 110. For example, the limb protector is disposable in covering relation to a portion of a thigh, shin, forearm, upper arm, or other portion of a limb adjacent to the joint being protected by the instant system 100. In one embodiment, the limb protector is an extension of the joint protector 110, and may be considered the same structure. In other embodiments, the limb protector is adjacent but connected to the joint protector 110, and may be hingedly connected thereto so as to allow for movement and flexion of the joint.
The present invention is amenable to various configurations. For instance, in some embodiments multiple systems 100 may be used in tandem, on different joints, such as a separate system 100 on each knee or each elbow. In at least one of these tandem embodiments, such as when one system 100 is employed over one elbow and another system 100′ is employed over the other elbow, the first attachment assembly 120 of each system 100, 100′ secures at or near the respective hand of the wearer, and the distal end 136 of the second attachment assembly 130 of one system 100 secures to the distal end 136′ of the second attachment assembly 130′ of the second system 100′. Accordingly, the distal ends 136, 136′ of the second attachment systems 130, 130′ meet and connect to each other at the back or shoulders of the person, even if they do not also attach to the person. In embodiments covering the knees, the distal ends 126, 126′ of the second attachment assemblies 120, 120′ may meet and connect at the shoulders, chest, or behind the neck. In still other embodiments, a single system 100 includes two joint protectors 110, each having its own first attachment assembly 120 to connect to the foot or hand, but sharing a common second attachment assembly 130, which may stretch over the back, shoulders, neck, or other part of the wearer.
Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
Now that the invention has been described,
