Standard youth sports protective gear is usually scaled-down from adult protective gear. For example, a standard youth catcher's leg guard is sized from an adult catcher's leg guard. But young players (e.g., players ages 6-12) present a varying range of anthropometric measurements and qualities along with age-appropriate ergonomic limitations and performance demands, so standard youth sports protective gear is generally sized without proper regard for anatomical proportions and variances present across the youth demographic. Accordingly, standard youth sports protective gear is often bulky or awkward, which results in discomfort and poor performance or protection for the young player. This is true for youth leg protection. Standard youth leg guards typically have fixed, single-piece shin protectors, or narrow central shin protectors (sometimes with foam to protect the sides of the leg), that suffer from inadequate anatomical adaptability and protection.
Standard youth catcher's leg guards also use decades-old buckle designs that latch onto a loop or ring on a side of the leg guard. The unsecured nature of such a design is prone to disengagement during play if a player has not properly tightened the straps or if the player has placed the buckle hook backwards. Such a problem is more pronounced for younger players who may be less diligent about securing their gear.
Finally, standard youth catcher's leg guards have straps that are looped through metal D-rings at the opposite ends of the straps from the buckle ends, on the opposite side of the leg guard. After tightening such a strap, a player desiring to loosen the strap has to feed the strap back through the D-rings, which involves picking at the edges of the strap with a fingernail to create a slack loop, and then pulling at the buckle end. This is complicated and time-consuming for youth players, especially those who share protective gear that consequently must be adjusted often.
Accordingly, there is a lack of anatomically dynamic and ergonomic youth-centric protective gear for baseball or softball catchers and other players.
A leg guard includes an anterior shin protective panel positioned to cover at least a portion of a user's anterior shin region, a lateral protective panel positioned to cover at least a portion of the user's lateral lower leg region, and a medial protective panel positioned to cover at least a portion of the user's medial lower leg region. The panels are mounted on one or more flexible liners in a vertically segmented orientation to articulate with respect to one another. Additional protective panels may be included to protect a user's knee, thigh, or foot. A strap for a leg guard may include a buckle having a protrusion positioned to engage an elongated opening in the leg guard. The strap may bias the buckle into a tilted position, while raised surfaces near the elongated opening resist release or rotation of the buckle.
Other features and advantages will appear hereinafter. The features described above may be used separately or together, or in various combinations of one or more of them.
In the drawings, wherein the same reference number indicates the same element throughout the views:

Turning now to the drawings,
Each of the thigh portion 110, the knee and shin portion 120, and the foot portion 130 may have a backing or support liner, such as a thigh liner 115, knee and shin liner 125, and foot liner 135. The thigh liner 115 may be flexibly connected to the knee and shin liner 125 by a fabric or elastic joint 116 or by a stitched connection, or the thigh liner 115 may be integral with the knee and shin liner 125. The foot liner 135 may be flexibly connected to the knee and shin liner 125 in a generally similar fashion. In one embodiment, the liners 115, 125, or 135 may include ethylene-vinyl acetate (“EVA”) foam as padding, covered in a fabric mesh or polyurethane vinyl. In other embodiments, the liners 115, 125, or 135 may include other suitable materials or combinations of materials, such a rubber padding covered in a moisture-wicking material. The knee and shin liner 125 may be symmetrical or it may be longer on one side than the other. For example, the shin liner 125 may be longer on a side corresponding to an outer or lateral side of a user's leg than on an inner or medial side of the user's leg, as generally illustrated in
Each of the thigh portion 110, the knee and shin portion 120, and the foot portion 130 may have one or more stiff, rigid, or resilient protective panels positioned thereon. For example, the thigh portion 110 may include a thigh protective panel 150 mounted on the thigh liner 115 to provide protection for a user's lower thigh or upper knee. In some embodiments, the thigh protective panel 150 may be generally coextensive with the thigh liner 115, or it may be smaller or larger in other embodiments. Similarly, the foot portion 130 may include a foot protective panel 151 mounted on the foot liner 135 to provide protection for a user's ankle or upper foot. In some embodiments, the foot panel 151 may be generally coextensive with the foot liner 135, or it may be smaller or larger in other embodiments.
As illustrated in
A vertically segmented arrangement, for example, allows the leg guard 100 to easily wrap around varying leg circumferences and to adapt to differences in anatomical proportions and variance, particularly in the youth demographic, without providing a bulky or awkward fit or sacrificing protection. For example, in one embodiment, a central or anterior shin protective panel 152 may substantially coextend with a region of the knee and shin portion 120 adjacent to an anterior portion of a user's shin bone region. An outside or lateral protective panel 153 may be generally positioned on the knee and shin liner 125 to coextend with an outwardly or laterally facing portion of a user's lower leg. And an inner or medial protective panel 154 may be generally positioned on the knee and shin liner 125 to coextend with an inwardly or medially facing portion of a user's lower leg. Because the panels 152, 153, 154 are vertically segmented, they can articulate to provide a better fit to a user's leg without sacrificing protection and coverage.
A knee protective panel 155 may be positioned on the knee and shin liner 125 to generally coextend with a lower or inferior anterior portion of a user's knee or an upper or superior anterior portion of a user's shin. Similarly, the flexible knee and shin liner 125 may allow the knee protective panel 155 to articulate with respect to the other panels 152, 153, 154. In some embodiments, the knee and shin liner 125 may be formed from a plurality of articulating liner portions, for example, one portion supporting the knee protective panel 155 and one or more portions supporting the shin protective panels 152, 153, 154.
Each of the protective panels 150, 151, 152, 153, 154, 155 may be made from a variety of suitable materials, including high-density polyethylene (“HDPE”), polypropylene (“PP”), or other plastic or metal materials that provide durable and resilient, rigid or semi-rigid, support and protection. And each of the panels may be formed to generally mimic the anatomical shape of the portion of the user's knee or leg coextending with a given panel. Accordingly, the protective panels 150, 151, 152, 153, 154, 155 provide sufficient structural rigidity and protection to the corresponding underlying portions of the user's leg while the liners 115, 125, 135 allow the leg guard 100 to conform to various shapes and sizes of the user's leg.
In some embodiments, one or more of the protective panels 150, 151, 152, 153, 154, 155 may have a raised surface, such as the illustrated raised surfaces 160, 161, 162, 163. The raised surfaces 160, 161, 162, 163 may be flat or angled surfaces to provide rigidity to the respective panels. In addition, some of the raised surfaces, such as the raised surface 162 on the anterior shin panel 152, and the raised surface 163 on the knee panel 155, may provide additional stability for the user if the user is postured such that these surfaces contact the ground. In yet other embodiments, the medial panel 154 may have indentations or trenches 164, 165 across the panel 154 that are shaped to accommodate the lower shin straps 142, 143 and to position the straps 142, 143 close to or below the surface of the medial panel 154 and to protect the straps 142, 143 from wear or abrasion.
In some embodiments, one or more of the protective panels 150, 151, 152, 153, 154, 155, or one or more of the liners 115, 125, 135, may further include vents to allow air to pass through the panels or the liners for cooling and drying the user's skin. For example, an intake vent 170 and an exhaust vent 175 on the anterior shin panel 152 may allow air to pass through an interior region of the leg guard 100 to cool and dry an underlying portion of the user's shin. Each vent may be indented or recessed into a panel.
The protective panels 150, 151, 152, 153, 154, 155 may be stitched to the liners 115, 125, 135 (for example, with the illustrated perimeter stitching 180). The panels may additionally or alternatively be riveted to the liners (such as with the illustrated rivets 185, for example). If stitched, each of the panels 150, 151, 152, 153, 154, 155 may have indentations, depressions, or walls 181 to position the stitching 180 below an exposed surface of the panels to protect the stitching 180 from wear or damage from abrasion. If riveted, the rivets 185 may also pass through the ends of the straps (e.g., 140, 141, 142, 143) to anchor the straps to the leg guard 100. In other embodiments, the panels may be attached to the liners in other ways, including with adhesive, for example.
The panels 150, 151, 152, 153, 154, 155 may include aesthetic curvature. For example, the shape of the panels, or the outline of the raised or indented surfaces or vents on the panels, may be designed to have an aggressive look or to otherwise be aesthetically pleasing.
In some embodiments, the straps 140, 141, 142, 143 may have buckles 190 that releasably engage elongated openings or slide-lock holes 195 in the protective panels, as further illustrated in
For example,
As shown in
The buckle 190 may engage with a slide-lock hole 195 (see
In operation, as illustrated in
The strap 142 may be wedged between the buckle 190 and the slide-lock area 610. In some embodiments, the strap 142 may be wedged between the strap-grabbing teeth 510 and the slide-lock area 610. When the strap 142 is wedged between the buckle 190 and the slide-lock area 610, there may be pressure between the buckle 190 and the slide-lock area 610 that causes the buckle 190 to tilt or bias toward the forward end 410. When the buckle 190 is tilted toward the forward end 410, the forward end 410 may be positioned generally lower than the raised surfaces 640 (e.g., as generally illustrated in
The raised surfaces 640 may be shaped or formed to help guide the protrusion 530 into the slide-lock hole 195 when a user is connecting the buckle 190 to the slide-lock hole 195 (to reduce the time required to don the guard 100, for example). The raised surfaces 640 may also resist or limit rotation of the buckle 190 about the hole 195 when it is connected to the slide-lock area 610. Accordingly, the leg guard 100 can be mounted to a user in a more secure and stable manner.
To detach a buckle 190 from a panel (i.e., 153) to remove the leg guard 100 from a user, the user pushes on the tail end 420 of the buckle 190 (e.g., inward toward the player's leg) to tilt the buckle 190 (e.g., about teeth 510) to raise the forward end 410 to generally release the buckle 190 from interference with the raised surfaces 640. When the forward end 410 is generally able to pass the raised surfaces 640, the user may push the buckle 190 out of the slide-lock hole 195. The tail end 420 may include an angular, textured, or otherwise grippy surface.
To tighten the strap 142, a user pulls on the strap end 430 (in the direction of the arrow 810 in
From the foregoing, it will be appreciated that specific embodiments of the disclosed technology have been described for purposes of illustration, but that various modifications may be made without deviating from the technology, and elements of certain embodiments may be interchanged with those of other embodiments. For example, in some embodiments, there may be more or fewer straps (such as straps 140, 141, 142, 143), slide-lock holes 195, or panels (e.g., 152), or there may be other suitable methods of affixing panels (e.g., 152) to underlying liners (e.g., 125). The slide-lock holes 195 need not be directly in the protective panels (e.g., 153), but they may be formed in intermediate metallic or plastic elements mounted to the protective panels, or they may be in other elements of a leg guard 100.
Further, while advantages associated with certain embodiments of the disclosed technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the technology. Accordingly, the disclosure and associated technology may encompass other embodiments not expressly shown or described herein, and the invention is not limited except as by the appended claims.
