L-SCREEN FOR PROTECTING A PITCHER
An L-screen for protecting a pitcher during batting practice is disclosed. The L-screen may include a plurality of panel frames configured to be interrelated with one another so as to form an L-shape. A solid protection panel may be mounted within each of the panel frames. The protection panel may be transparent so as to provide an unobstructed view through the protection panel and may have adequate strength to withstand the impact of a baseball hit by a batter. Additionally, the L-screen may include support structure mounted to and configured to support the L-screen.
The present invention relates generally to an L-screen for protecting a pitcher during batting practice and particularly to an L-screen with transparent panels configured to withstand the impact of a baseball hit by a batter while providing an unobstructed view through the L-screen.
BACKGROUND OF THE INVENTIONBaseball players take batting practice to prepare for a game or to simply develop or improve their swing. During batting practice, a pitcher typically stands on or near the pitcher's mound and throws multiple pitches to a batter, with each pitch generally being delivered at a reduced speed to allow the batter to make solid contact with the ball. As a result, the pitcher is highly susceptible to being struck by a low line drive hit in the direction of the pitcher's mound. Accordingly, it is common for a pitcher pitching batting practice to stand behind a protection screen, often configured as an L-shaped device and referred to as an “L-screen.” Known L-screens typically include an L-shaped frame with netting secured within or around the frame to deflect balls hit towards the pitcher. As is generally understood, the “L-shape” of the L-screen allows the pitcher to pitch over a horizontal or short portion of the L-screen while standing behind a vertical or tall portion for protection
In many instances, the coach of a baseball team may pitch batting practice. As such, it is essential that the coach have an unobstructed view of the batter so that the coach can properly instruct the batter with regard to his/her stance or swing. Additionally, it also important that the batter taking batting practice have an unobstructed view of the pitcher. For example, being able to carefully view the pitcher's throwing motion can enable the batter to improve his/her timing and reaction as the pitch is delivered.
Regarding both of the scenarios described above, it has been found by the present inventors that the netting in a conventional L-screen provides a coach pitching batting practice with a less-than-optimal view of the batter and provides a batter taking batting practice with a less than optimal view of the pitcher. As such, player instruction, as well as player self-improvement, can be significantly hindered. Moreover, it has also been found that the netting used in L-screens often fails to provide adequate protection for a pitcher. For example, portions of the netting can tear, which may create openings in the netting large enough for a baseball to penetrate. Additionally, the netting may deteriorate over time, which can result in failure of the netting and place the pitcher in danger of being harmed by a hit baseball passing through the L-screen.
Accordingly, there is a need for an L-screen that provides both adequate protection for the pitcher and an unobstructed view through the L-screen.

A full and enabling disclosure of the present invention, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures, in which:
Reference now will be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the present invention, not by way of limitation. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the present invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
In accordance with an aspect of the present invention, an L-screen is provided for protecting a pitcher during batting practice. Thus, the L-screen is very durable, being capable of withstanding the impact of a baseball hit by a batter. The L-screen according to the present invention also enhances the ability of a coach to instruct his players during batting practice. In particular, the protection panels mounted within the L-screen are transparent so as to provide an unobstructed view through the L-screen. Additionally, the L-screen may be designed to be lightweight, thereby making the L-screen extremely portable. Further, the L-screen may be collapsible or foldable into a relatively compact size. As such, the L-screen can be stored in numerous locations, such as in the trunk of a car or in an equipment locker at a baseball facility.
Referring to the drawings,
Generally, the panel frames 12,14,16 may be configured to be interrelated with one another so as to form the shape of a capital “L.” In a preferred embodiment, shown in
It should be appreciated that the L-screen 10 may include any suitable retaining mechanism configured to maintain the panel frames 12,14,16 in the open position. In one embodiment, shown in
Further, one of ordinary skill in the art should appreciate that the panel frames 12,14,16 may be rotatably attached to one another by any suitable means. Generally, any attachment mechanism that allows rotational, folding or pivotal motion between the adjacent panel frames 12,14,16 may be utilized within the scope of the present invention. In the illustrated embodiment, hinges 26 are secured between the panel frames 12,14,16 to provide rotational attachment.
Additionally, it should be appreciated that all of the panel frames 12,14,16 need not be rotatably attached to one another. In alternative embodiments, shown in
Referring to
In yet another embodiment, all of the panel frames 12,14,16 may be removably attached to one another. For example, the panel frames 12,14,16 may be configured to be secured together to form the “L-shaped” L-screen 10 and also configured to be disassembled into a plurality of separate components. In such an embodiment, attachment brackets 82, retaining pins 58, or any other suitable attachment means may be used to removably attach the panel frames 12,14,16 together.
One of ordinary skill in the art should appreciate that the panel frames 12,14,16 may be formed from various materials. For example, the panel frames 12,14,14 may be formed from various metals, such as steel or aluminum. Alternatively, the panel frames 12,14,16 may be formed from various plastics, such as PVC, various composite materials, such as fiberglass or carbon fiber, or generally any other suitable material. Additionally, the cross-section of the panel frames 12,14,16 may have any suitable geometry. For example, the panel frames 12,14,16 may have a circular, oval, square, rectangular, triangular, trapezoidal or other similar shaped cross-section. Further, the cross-section of each panel frame 12,14,16 may be hollow, solid, partially solid, or the like.
In a preferred embodiment, it may be desirable to choose a lightweight panel frame material with a cross-section designed to minimize the overall weight of the panel frames 12,14,16. As such, the L-screen 10 may be easily transported and stored between uses. For instance, in one embodiment, the L-screen 10 may have a total weight of less than about 50 pounds, such as less than about 40 pounds or less than about 25 pounds. It should be appreciated, however, that the weight of the L-screen 10 is not entirely dependent on the panel frames 12,14,16, and thus, the total weight may vary depending on the weight of other L-screen components, such as the protection panels 18.
Referring to
Further, as has been generally described above, a preferred L-screen includes three panel frames 12,14,16. However, it should be appreciated that, in alternative embodiments, the L-screen 10 may include any number of panel frames, For example, the L-screen 10 may only include two panel frames. In such an embodiment, one frame may form the tall, vertical section of the “L-shape” and another may form the shorter section, or vice versa. In still another embodiment, the L-screen 10 may include more than three panel frames, such as four, six or eight panel frames.
The L-screen of the present invention also includes a protection panel 18 mounted within each panel frame 12,14,16. In general, each protection panel 18 may include a solid, continuous plate of clear or transparent material. As such, the protection panels 18 provide an unobstructed view through the L-screen 10. This transparency is desirable to provide complete protection for a pitcher during batting practice. For instance, a fully transparent protection panel 18 can ensure that the pitcher has a clear view of the baseball immediately before and after it is hit by a batter. As such, the pitcher may possess the greatest amount of time possible to react to a line-drive hit back towards the pitcher's mound. For example, the unobstructed view of the transparent protection panel 18 may give a pitcher sufficient reaction time to ensure that his/her throwing arm and/or other body parts are safely behind the L-screen 10 prior to a hit baseball reaching the pitcher's location.
Moreover, a clear or transparent protection panel 18 can also maximize the effectiveness of player instruction. For example, as described above, it is often the case that the coach of a baseball team pitches batting practice to enable the entire team to take batting practice without the necessity of switching pitchers. Additionally, coaches often meet with players one-on-one to provide individualized batting practice and, thus, may be required to pitch out of necessity. In both scenarios, the coach will typically give his/her players instruction related to their batting stance, swing, timing, or the like. Thus, it may be particularly desirable for a coach to have the fully unobstructed view provided by the transparent protection panels 18 of the present invention to permit the coach to render the most effective instruction for his/her players.
Various transparent materials may be used within the scope of the present invention to form the protection panels 18. In general, the material chosen for the protection panels must be capable of withstanding the impact of a baseball hit by a batter. In other words, the material chosen must have adequate strength to withstand the force of a baseball hit by a baseball bat. Thus, it should be appreciated that the protection panels 18 may be formed from various high impact plastic or polymer materials. In a preferred embodiment, each protection panel 18 may be formed from a solid, transparent plate of polycarbonate. In alternative embodiments, the protection panels 18 may be formed from solid, transparent plates of polyvinyl chloride (PVC), acrylic, polyethylene terephthalate glycol (PETG) or any other suitable material so long as the desired characteristics according to the current invention are present.
It should be readily appreciated that the required thickness needed to enable a protection panel 18 to have adequate strength to withstand the impact of a baseball hit by a batter will generally vary depending on the panel material chosen. Additionally, the thickness of the protection panel 18 may vary depending on the desired weight of the L-screen 10. In particular, as indicated above, it may be preferable that the L-screen 10 be relatively lightweight so that it can be easily transported to and from a baseball field. Thus, in one embodiment, the thickness of the protection panel 18 may be less than about 1 in., such as less than about 0.5 in., or less than about 0.25 in. In a preferred embodiment, it has been found that an approximately 0.1875 in. thick polycarbonate plate can provide a lightweight protection panel 18 that has adequate strength to withstand the impact of a baseball hit by a batter. One of ordinary skill in the art should also appreciate that the rigidity of the protection panels 18 may vary depending on the material chosen. For example, the protection panel 18 may be formed from a rigid or a semi-rigid transparent material.
Moreover, as shown in the illustrated embodiments, the protection panels 18 may be rectangular in shape to generally fit within the rectangular shaped panel frames 12,14,16. However, it should be appreciated that the protection panels 18 may have any suitable shape depending generally on the configuration and shape of the panel frames 12,14,16. For instance, if the panel frames 12,14,16 are designed so as to be circular or triangular in shape, it may be desirable to have circular or triangular shaped protection panels 18, respectively, to fit within the frames 12,14,16 and provide sufficient protection for the pitcher.
Each protection panel 18 may be mounted within a panel frame 12,14,16 by any suitable means. In one embodiment, a plurality of mounting brackets 32 may extend inwardly from each panel frame 12,14,16 to permit the protection panels 18 to be secured within the frames 12,14,16. For example, as shown in
Various other mounting configurations may be used within the scope of the present invention to mount the protection panels 18 within the panel frames 12,14,16. For example, as shown in

In one embodiment, the support legs 36 may be configured so that the mountings posts 40 are not centered on the laterally extending base 38, thereby creating an offset construction in each leg 36. Such an offset construction may provide even further stability for the L-screen 10 when the screen is in an upright, vertical open position. Thus, as shown in
Additionally, it should be appreciated that each leg 36 may include one or more downwardly extending elements 46, such as a spike, stake or the like. Accordingly, as illustrated in
As described previously, the panel frames 12,14,16 of the present invention may be movable or rotatable from an open “L-shaped” position to a closed “compact” position. Particularly, in one embodiment, the panel frames 12,14,16 may be configured to be folded or rotated together into a very compact structure (
To improve the portability of the L-screen 10, the L-screen may also include a locking mechanism 48 configured to lock the panel frames 12, 14, 16 into the closed position.
