This invention provides an elbow-area and knee-area protector that fits over a person's arms and legs, for protection during contact and collision sporting activities.
Contact and collision sports involve any sport in which physical contact between players is an accepted type of play. In collision sports (i.e. boxing, wrestling, cage-fighting, hockey, football, lacrosse, and rodeo), athletes purposely hit or collide with each other or with inanimate objects (including the ground) with great force. In contact sports (i.e. basketball, volleyball and soccer), athletes make contact with each other or inanimate objects but usually with less force than in collision sports. Due to the risk of injury associated with contact and collision sports, protective equipment is often encouraged and even required.
Cage-fighting is a type of mixed martial arts, where two individuals fight in a cage, and it involves extreme and violent combat. In sports like cagefighting, it is common for the athlete to use striking and grappling techniques. Striking techniques involve punching, elbowing, kicking, and kneeing while grappling techniques involve sweeps, takedowns, throws, cinch holding, pin holding, and submission holding. Therefore, it is imperative that the elbows and arms, and knees and legs, be protected in order to prevent injury.
The elbow and knee are synovial hinge joints susceptible of injury which need to be protected. But presently available protection for the elbow and knee can be restrictive of movement, which diminishes a person's performance during contact and collision sporting activities. The act of bending the elbow and the knee requires the olecranon or tip of the elbow, and the patella or knee cap, to thrust outward in relation to the rest of the arm or leg. Presently available protection tends to restrict that outward thrust, which prevents optimum movement of the whole body and prevents optimum use of the arms and legs and elbows and knees for offensive and defensive purposes.
Lohman, U.S. Pat. No. 5,887,277, discloses a protective pad for the elbow formed from a layer of flexible, resilient padding material having a width and length. The length of the padded material is divided into forward and rearward sections by a line, which extends across the padding material's width. The forward section overlays the forearm and the rearward section overlays the user's upper arm. A hole is formed in the padded material and receives the user's elbow when the padded material is secured to the arm. A strap is coupled to the layered padding material and is used to secure the padding material to the user's elbow.
The prior art uses solid, continuous blocks or layers of padding, held in place with straps, to protect the elbow or knee from impact, but such pads are not only restrictive of movement, they also tend to slip out of place as the joints are moved, which can leave the joint unprotected or can further restrict movement. A problem with this typical elbow pad model is that it easily becomes dislocated and slides out of place.
Besides protecting the elbows and the knees, it is desirable to also protect the arms and the legs where they meet to form the elbows and knees. Those areas are used both offensively and defensively, and need the same protection as the elbows and knees themselves. But extension of padding to those areas restricts movement even more than just padding the joint itself.
Because the elbows and knees, and the adjacent parts of the arms and legs, are used both offensively and defensively, the protection provided should either enhance, or at least not diminish, the offensive in favor of the defensive. For example, a large amount of highly shock-absorbing padding might be very effective protection for the elbows and knees of the person throwing the punch, but the effect on the person receiving the punch is diminished to the equivalent of being hit very hard with a pillow. Cage-fighting becomes pillow-fighting.
There is a need for a more flexible and durable way of protecting the elbow-and-knee area which fits securely but comfortably and remains secure during contact and collision sporting activities while providing shock absorption and protection from injury without limiting the offensive and defensive uses of the elbows and knees.
The present invention provides an articulated tripartite elbow-and-knee-area protector and method for protecting a person's elbow-and-knee areas from injury during contact and collision sporting activities, without restricting movement and without limiting the offensive and defensive uses of the elbows and knees.
The present invention solves several existing problems of too much restriction, limitation, and discomfort, and too little protection of the elbow-and-knee areas, in contact and collision sporting activities, and of defensive protection that limits the offensive use and effectiveness of elbows and knees.

Referring to
Attached to the flexible sleeve 10 as shown are the joint pad unit 20, the distal pad unit 30, and the proximal pad unit 40. The three pad units are separate and are designed to fit over or under the other as shown. Each pad unit is made of open-cell foam, closed-cell foam, neoprene, or similar material. Preferably, layers of different materials are used in order to obtain the optimal shock-absorbing qualities plus the optimal durability and outer-surface qualities.
The distal pad unit 30 and the proximal pad unit 40 are flat, oblong pads adapted to protect portions of the forearm and upper arm, or shin and lower thigh. In a preferred embodiment, the distal pad unit 30 and proximal pad unit 40 are approximately one-quarter to three-eighths of an inch thick, and are sized to fit the areas adjacent to the joint as shown. Distal pad units 30 of length 6-to-8 inches for the forearm and 8-to-10 inches for the shin, and proximal pad units 40 of length 4-to-6 inches for the upper arm and 6-to-8 inches for the lower thigh, would fit the average person properly.
The joint pad unit 20 has a sectional shape something like a mushroom, as shown. The size of the joint pad unit 20 is sufficient to provide the functions and the functional areas disclosed here. For average use, an outer-surface area of 2.5-to-3 square inches, and a thickness at the thickest point of 1-to-2 inches is appropriate.
The distal pad unit 30 and the proximal pad unit 40 have outer surfaces 6 and the joint pad unit 20 has an outer surface 7. The surfaces can be made of the same or of different materials. The outer surfaces 6, 7 should be durable and should be appropriate for both offensive and defensive use of the protected joint area. The outer surface should not be too soft, because that would limit offensive effectiveness, but should not be so hard or sharp as to become in itself a weapon. The outer surfaces can either be the normal surface of the outer layer of padding 2 as shown in
The three pad units 20, 30, 40 are permanently affixed to the flexible sleeve 10 with a glue, epoxy, or similar method, with the entire inner surface of each pad being affixed to the flexible sleeve. At the attachment areas 11 the sleeves lose their flexibility because the flexible material is glued to more rigid pad units. Unattached areas 12 are provided between the three pad units and therefore between the three attachment areas 11. The unattached areas 12 retain their flexibility and ability to be bent, and, in combination with other elements disclosed herein, form articulations among the three pad units.
Referring additionally to
The joint pad unit 20 has a convex top 21 forming a thickest part generally in the middle of the joint pad unit. The sides of the joint pad unit which are oriented toward the distal pad unit 30 and the proximal pad unit 40 each have an overhanging extended portion 22 and an undercut retracted portion 23 forming void spaces adapted to accommodate the distal pad unit 30 and the proximal pad unit 40 as shown. The joint pad unit 20 has a concave bottom 24 which is smaller than the rest of the joint pad unit by the size of the two undercut retracted portions 23.
In use, along the line of the attachment areas 11 of the distal pad unit 30, joint pad unit 20, and proximal pad unit 40 the otherwise flexible sleeve 10 can only bend at the two unattached articulation areas 12 because the attachment areas 11 are resistant to bending. Therefore, the only area that can be pushed out by a bending elbow or knee is the concave bottom 24 of the joint pad unit. The concave bottom 24 provides additional space for the elbow or knee. Together, the concavity of the bottom and its being the only area that will bend not only accommodate the bending joint, but also serve to reposition the articulated tripartite elbow-and-knee-area protector into the correct position every time the joint is bent.
In use, when the elbow or knee are bent, the outward thrusting of the olecranon or tip of the elbow, and of the patella or knee cap, will push the concave bottom 24 of the joint pad unit away in a direction essentially perpendicular to the former line of the straight arm or leg. The same bending action will also rotate the distal pad unit 30 and the proximal pad units 40 in opposite directions down and away from the former line of the straight limb. The undercut retracted portions 23 of the the joint pad unit 20 provides freedom for the rotation, and the lifting action of the joint pad unit provides additional space. The overhanging extended portion 22 of the joint pad unit extends essentially to the positions of the distal and proximal pad units 30, 40 when the limb is bent, and therefore avoids creating any gap in the protected area. When the limb is straightened again, the three pad units return to their interleaved positions.
Many changes and modifications can be made in the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.
