Abstract

The present invention provides a protective pad for the limbs of a person that is operable to connect to the clothing of the person to prevent slippage of the knee pad as the wearer moves. In some embodiments, the pad may be operable to be used for the elbows of the body. The protective pads include connector straps integrated into the side edges of the pads that are operable to wrap around the wearer's leg and connect to connectors on the opposite side edge of the knee pad. The protective pads may additionally have at least one anti-slip retention strap for connecting directly to the pants of the wearer.

Description

FIELD OF THE INVENTION

The present invention relates to protective pads worn on the body, such as kneepads, that are operable remain in proper position without constricting the motion of the wearer, and methods of using the same.

DISCUSSION OF THE BACKGROUND

Protective kneepads have been available for people to wear on their bodies, such as kneepads, elbow pads, shin pads, thigh pads, forearm pads, etc. The pads protect the limbs of the body from injury and provide comfort to the wearer. Some pads have straps that are connected to the edges of the pads and extend about the limb so as to have enough frictional contact to cling to the leg, arm, etc. Typically, the pads require upper and lower straps for connection to the limbs. For example, kneepads usually have upper straps to be wrapped from the upper portions of the kneepads around the legs above the knees and lower straps to be wrapped around the legs below the knees. If the straps are drawn tightly about the limb, they tend to hold the kneepad in place, but the tighter the straps the more constriction and discomfort there is about the limbs. This generates an undesirable constriction in the blood flow and discomfort to the wearer. Consequentially those who wear kneepads tend to attach the straps as loosely as possible in order to reduce the discomfort and as a result the kneepads have a propensity to slip out of position.
Also, when the wearer of kneepads is in the kneeling position, it is highly desirable to have the kneepads properly placed at the knee for maximum effect. However, when the wearer stands and the knee is straightened, the pants of the wearer become somewhat bunched above the kneepad, and there is some tendency of the kneepads to slip downwardly with the pants, to a position lower than the desired position. When the wearer returns to the kneeling position, the constriction of the straps tends to impede the lifting movement of the kneepads that is necessary to move the kneepads back up to the desired position at the knee. If the straps are tightly drawn to avoid downward movement of the kneepads when the wearer moves to the standing position, the pants of the wearer will remain bunched above the knee.

SUMMARY OF THE INVENTION

The present invention provides a protective pad for the limbs of a person that is operable to connect to the clothing of the person to prevent slippage of the knee pad as the wearer moves. In some embodiments, the pad may be operable to be used for the elbows of the body. The protective pads include connector straps integrated into the side edges of the pads that are operable to wrap around the wearer's leg and connect to connectors on the opposite side edge of the knee pad. The protective pads may additionally have at least one anti-slip retention strap for connecting directly to the pants of the wearer. The at least one anti-slip strap may extend from the upper edge of the pad and extend upward so that it can connect to the wearer's pants above the kneepad such that it will prevent the kneepad from slipping down the leg when the wearer stands, kneels, sits, and/or engages in other movements. The at least one anti-slip strap allows for the kneepad to be maintained such that the bottom portion of the pads generally tend to rest against the lower limb, such as the shin below the knee, whereas the upper portion of the pad extends to a point just above the kneecap. As a result, when the wearer of a kneepad is in the kneeling position, the upper portion of the kneepad will project outwardly under the knee, out toward the front of the wearer, thus providing cushioning for the kneecap, while the lower portion is beneath the knee, protecting the shin.
The kneepad may include a protective shell including a convex outer surface and a concave inner surface and lateral edges. The connector straps are integrated into one or both lateral edges of the protective shell and a connection hook, slot or other coupling device may be positioned on the opposite lateral edge of the kneepad to allow the connector straps to wrap around the back of the leg and connect to the opposite side of the kneepad. The connector straps may be integrated into the outside surface of the kneepads or the connector straps may be positioned on the inside surface of the kneepads. In some embodiments, the connector straps of the protective pad may be mounted to the pads at approximately one-half the height of the pads, such that the kneepads may be centered over the knee when it is donned. In some embodiments, the protective shell with an array of openings extending therethrough to allow air flow to allow air flow and drying of the underlying cloth and skin.
In some embodiments, the protective shell of the kneepad may be made of a rigid material such as thermoplastic urethane, polypropylene or various other rigid yet flexible materials. In some embodiments, the kneepad may include a layer of material softer than the protective shell is in contact with the inner surface of the protective shell to provide some padding and comfort for the wearer's leg, and reduce the likelihood of injury. The soft material may also include an array of openings that align with the openings in the protective shell. The layer of soft material may be made of various materials, such as foam rubber, various forms of soft plastics, such as thermoplastic elastomer, cotton batten, quilted cotton batten, other suitable materials, and combinations thereof (e.g., in a multilayer structure).
The at least one anti-slip strap may extend from the upper edge of the kneepad. The at least one anti-slip straps of the kneepads may be integrated into the kneepad at a location on the upper edge of the kneepad. The anti-slip strap may be fixedly connected to the upper edge of the kneepad, e.g., by adhesive, stitching, rivets, or other fixation elements. The anti-slip strap may have a length in a range of about two inches to about ten inches, and may have a clasp operative to reliably connect to the fabric of a pair of pants (e.g., denim, canvas, cotton, etc.). The clasp may be an alligator style clip, bulldog clip, and other strong spring-loaded clip. The clasp may include teeth in the distal edge of the of the clip to grasp the fabric of the pants. The strong clips provide firm connections between the kneepads and the pant legs, so that the kneepads tend to maintain a firm position at the knees of the wearer.
In some embodiments, the one anti-slip strap may be detachable from the kneepad. For example, a first end of the at least one anti-slip strap may have a locking connector operable to reversibly connect the first end of the strap to a receiver in an upper edge of the kneepad. The lockable connector may be a lockable carabiner clip, locking snap hooks, or other lockable clips. The anti-slip strap may have a second end with a clasp operative to reliably connect to the fabric of a pair of pants (e.g., denim, canvas, cotton, etc.). The clasp may be an alligator style clip, bulldog clip, and other strong spring-loaded clip. The clasp may include teeth in the distal edge of the of the clip to grasp the fabric of the pants.
In some embodiments, the kneepad may include a plurality of anti-slip straps to allow for additional support to the kneepad. The kneepad may include at least two anti-slip straps which provides two connection points with the wearer's pants to add stability. For example, the kneepad may include collateral left and right anti-slip straps allowing one to be attached to the right portion of a pant leg and the other to be attached to the left portion of the pant leg. Such an arrangement aids in preventing rotation of the kneepad around the leg as the wearer moves. In other embodiments, the kneepad may include three or more anti-slip straps.
The present invention provides a protective pad for the limbs of a person that connects to the clothing of the person, particularly when the person expects to encounter abrasion, impact, weight or other discomfort to the limb. The invention may be designed and used for the arms or legs of the body.
