The present invention relates to sports equipment, and in particular to a leg guard for a baseball or softball catcher.
Baseball and softball catchers are positioned behind home plate and perform many important functions during a game, from calling plays and protecting the plate to catching the ball thrown by the pitcher. Due to impacts from pitches, sometimes in excess of 90 mph, and home plate crashes with other players, the bodies of catchers are regularly exposed to physical trauma.
One particular physical injury that catchers are especially prone to is knee injuries. Due to the crouching position catchers assume behind home plate, catchers commonly injure their knees. For instance, the crouching position exposes the inner legs of a catcher to impacts from pitches. Because of this exposure, the inner side portions of a catcher's knees are often struck by the ball. Collisions at home plate from opposing team players trying to score also often result in slides that impact or injure the catcher's lower legs and knees. These types of injuries can seriously hinder the catcher's ability to perform vital functions during the game.
Current leg guards exist that provide some protection to the knee, thigh, and shin areas. Existing leg guards typically include a triple kneecap design, where three separate protective paddings come together to cover and protect the knee. For example, U.S. Pat. No. 4,692,946 to Jurga describes a triple kneecap design where a pair of flexible straps is utilized to secure the knee guard, first thigh guard, and second thigh guard to each other. The leg guards usually include additional protective padding to protect the thigh and shin portions of the leg. However, existing triple kneecap designs do not provide sufficient protection for the inner side portions of a catcher's knees.
In addition, catcher's leg guards are attached around the legs utilizing elastic connecting straps that rely on squeezing the leg guards against the wearer's leg to keep the leg guard in place. Because there is nothing outside of the friction between the straps/leg guards and the leg/uniform of the wearer to counteract the vertically downward force of gravity, it is common for leg guards to sag in use especially when the user goes from the crouched position to the standing position and back. For example, a catcher's blocking motions for stopping wild pitches requires that the catcher drop quickly onto their knees from the crouching position and just as quickly either reassume the crouching position or stand upright to throw out any potential base stealers. In doing so, the pads of the catcher's leg guard often become misaligned and mispositioned. When a catcher assumes the crouching position, the leg guard slides down the leg of the catcher about 3 inches. However, when the catcher reassumes a standing upright position from the crouching position, the leg guard does not slide back up into place to protect the thigh. Not only can this be distracting to the catcher, but it also requires the wearer to constantly pull up on the leg guards to reposition and align them on the leg of the wearer.
Further, to try and accommodate this shifting of the leg guard due to the movement of the wearer, current leg guards connect the knee plate and the thigh plate with connectors, such as flexible elastic straps or braided straps, that can only hold the knee plate and thigh plate in the proper position when under tension, i.e., the straps are pulled on from one or both ends. When compression is applied by the weight of the thigh plate on top of the knee plate, i.e., the straps are pressed on from one or both ends, the flexible nature of the straps is not able to apply any force to keep the knee plate and thigh plate separated. This results in the thigh plate and knee plate coming closer together and ultimately leads to the unwanted sagging of the leg guards and resulting in the entire leg guard not fitting properly.
To attempt to accommodate this issue, U.S. Pat. Nos. 10,293,241 and 11,058,939 to Rodrick et al,. each of which are expressly incorporated herein by reference in their entirety for all purposes, disclose a leg guard for a catcher in which the portion of the leg guard covering the thigh and the portion of the leg guard covering the knee are interconnected by a pair of hinge arms integrally formed with the thigh portion. The hinge arms are rotatably connected to the knee portion to rotate with regard to the knee portion when the catcher bends his or her knee. The hinge arms are formed of the same material as the cover plate of the thigh portion and thus do not stretch, bend or flex, thereby maintaining the position of the knee portion relative to the thigh portion during use of the leg guard.
However, while able to maintain the position of the portions of the leg guard over the knee of the wearer during use, the rigid nature of the hinge arms significantly reduces the flexibility of the leg guard with regard to any non-linear movement of the leg of the catcher, e.g. and twisting or lateral movement. This can impair the movement of the wearer and thus there still remains a need for a leg guard that more adequately protects the catcher's knees and allows catchers to freely and quickly move to or through different stances without having to re-position the pads of the leg guard.
According to one exemplary embodiment of the present disclosure, a leg guard is provided with a spined splint that connects the knee plate with the thigh plate. The splint is made of a material and shaped in a way that allows the splint to hold tension like a rope, to hold compression like a support beam, to bend in one plane like a single hinge through the full range of the knee joint, and to twist slightly and to create and maintain a consistent separation distance between the knee plate and the thigh plate while the leg guard including the splint is being worn.
According to another exemplary embodiment of the disclosure, a leg guard includes a first guard, a second guard, and a connector secured between the first guard and the second guard, wherein the connector is formed of a material that is flexible but resistant to stretching and compression forces.
Other objectives, features, benefits and advantages of the present invention will be apparent from this summary and its descriptions of certain embodiments of such formulations and compositions, and will be readily apparent to those skilled in the art having knowledge of the synthetic techniques described therewith. Such objectives, features, benefits and advantages will be apparent from the above as taken into conjunction with the accompanying examples, data, and all reasonable inferences to be drawn therefrom.
The drawings illustrate the best mode currently contemplated of practicing the present invention.

As best shown in
The splint connector 50 is formed to be able to maintain its shape when placed under compression or tension forces, such that the splint connector 50 will not appreciably stretch or contract/compress when these forces are exerted on the splint connector 50, but that allows the splint connector 50 to hold tension like a rope, to hold compression like a support beam, to bend in one plane like a single hinge through the full range of the knee joint, and to twist slightly and to create and maintain a consistent separation distance between the knee plate and the thigh plate while the leg guard including the splint is being worn such that the splint 50 can bend and/or flex and/or twist, thereby accommodating the natural movements of the leg of the user wearing the leg guard 100 without restricting movement, including twisting or lateral movement of the thigh relative to the lower leg and/or knee, unlike the restrictive hinges utilized in prior art leg guards such that those in the '241 and '939 patents. This attribute of the splint connector 50 can be provided directly by the material selected to form the splint connector 50, and/or by a separate component of the construction for the splint connector 50 that is added to the connector 50. Suitable materials that the splint connector 50 can be formed of include various polymers including one or more thermoplastic polymers, such as acrylonitrile butadiene styrene (ABS), a flexible ABS, a high density polyethylene (HDPE) or a low-density polyethylene (LDPE), and combinations thereof, among others. This material enables the upper portion 52 and the lower portion 54 to be affixed to the adjacent thigh guard 10 and knee guard 6, respectively, using any suitable means through the flexibility of the material, while maintaining the structural integrity or compressibility of the material. The inclusion of the strips 58, 60 between each of the upper portion 52 and lower portion 54 and the central portion 56 lessens the rigidity of the connector 50 at the locations of the strips 58, 60, providing enhanced flexibility and twisting of the connector 50 at those points. As the locations of the strips 58, 60 are generally aligned with the upper end of the knee guard 8 and the lower end of the thigh guard 10, the strips 58, 60 allow for flexing and limited twisting of the knee guard 6 relative to the thigh guard 10
In another exemplary embodiment the splint connector 50 can include one or more spines 62, as shown in
In any embodiment, the placement of the splint connector 50 extending between the knee guard 6 and the thigh guard 10, and beneath the extended knee guard 8, enables the splint connector 50 to flex and/or twist, to allow the knee guard 6 and thigh guard 10 to move with regard to one another when the wearer move between a standing position and a crouching position. However, the material forming the connector 50 also prevents compression of the connector 50, preventing the length of the splint connector 50 between the knee guard 6 and the thigh guard 10 to be altered as a result of the forces exerted on the splint connector 50. This function of the splint connector 50 maintains a consistent separation between the knee guard 6 and the thigh guard 10 throughout the movement of the leg guard 100 while enabling the wearer to freely move the knee joint through its full range of motion as well as to accommodate for limited twisting motion of the upper and/or lower portions of the leg relative to the knee joint. This is more clearly illustrated in
In alternative embodiments, the splint connector 50 can be positioned between other adjacent individual or multiple pairs of guards 2, 4, 6, 8, 10 forming the leg guard 100, and can be employed as the sole connector between one or more adjacent pairs of guards 2, 4, 6, 8, 10 forming the leg guard 100, or can extend the length of the leg guard 100 as a single connection between each adjacent pair of guards 2, 4, 6, 8, 10. Further, the splint connector 50 can be formed with a sufficient thickness and/or a cushion or padding layer (not shown) thereon to enable the splint connector 50 to function as or replace one or more cushion pads 12, 16, 22, 26, 30, 34 of the leg guard 100.
