Embodiments relate generally to protective sports equipment and more particularly to protective field screens.
Protective field screens are often used in ball sports, such as baseball, football, golf, soccer or lacrosse, to protect individuals and equipment from being struck by balls. In the sport of baseball, for example, a “pitching screen” may be placed between a pitcher and a batter to protect the pitcher from balls struck by the batter. Similar types of protective field screens can be placed in front of other players or equipment to protect them from balls or other objects.
Protective field screens can enhance safety of persons and equipment. Unfortunately, existing protective field screens have shortcomings. For example, protective field screens are typically formed of netting strung about a frame, and, although the netting may absorb impacts of balls that strike the net, balls that strike the frame may damage the frame or deflect off the frame and strike persons or equipment.
Provided are embodiments of a protective field screen (or “field screen”) having in impact absorption system (or “dampening system”). In some embodiments, the dampening system includes one or more resilient members disposed between a base frame (e.g., a lower frame portion of the field screen that rest on the ground or other supporting surface) and screen frame (e.g., an upper frame portion of the field screen that supports a protective netting). For example, the screen frame may be coupled to the base frame by way of resilient members. In such an embodiment, the resilient members may deform to facilitate movement (e.g., pivoting) of the screen frame (and the protective netting) relative to the base frame. The movement may provide dampening that enhances the field screen's ability to absorb impacts, which can, in turn, enhance durability and protection offered by the field screen. For example, with regard to durability, the enhanced dampening of impacts to the frame may inhibit denting, cracking or breaking of the frame. With regard to protection, the enhanced dampening of impacts to the frame (or the protective netting) may help to absorb the energy of a moving (or “flying”) ball such that the ball stops and “falls down” to a foot of the field screen or deflects off the field screen at a relatively low speed.

Provided are embodiments of a protective field screen (or “field screen”) having in impact absorption system (or “dampening system”). In some embodiments, the dampening system includes one or more resilient members disposed between a base frame (e.g., a lower frame portion of the field screen that rest on the ground or other supporting surface) and screen frame (e.g., an upper frame portion of the field screen that supports a protective netting). For example, the screen frame may be coupled to the base frame by way of resilient members. In such an embodiment, the resilient members may deform to facilitate movement (e.g., pivoting) of the screen frame (and the protective netting) relative to the base frame. The movement may provide dampening that enhances the field screen's ability to absorb impacts, which can, in turn, enhance durability and protection offered by the field screen. For example, with regard to durability, the enhanced dampening of impacts to the frame may inhibit denting, cracking or breaking of the frame. With regard to protection, the enhanced dampening of impacts to the frame (or the protective netting) may help to absorb the energy of a moving (or “flying”) ball such the ball stops and “falls down” to a foot of the field screen or deflects off the field screen at a relatively low speed.
The body relative directions referred to here are intended to provide an understanding of the relative locations of components of the field screen 100. In accordance with the coordinate system axes illustrated in the figures (unless indicated otherwise), “left” may refer to the positive “x” direction, “right” may refer to the negative “x” direction, “front” (or “forward”) may refer to the positive “y” direction, “back” (or “rearward”) may refer to the negative “y” direction, “up” (or “upward”) may refer to the positive “z” direction (e.g., away from the ground), and “down” (or “downward”) may refer to the negative “z” direction (e.g., toward the ground). “Lateral” may refer to orientation or movement in the x direction. “Longitudinal” may refer to orientation or movement in the y-direction. “Vertical” may refer to orientation or movement in the z-direction.
The screen frame system 102 may be a structure that provides a physical barrier that is operable to absorb impacts of sports balls and other objects. In some embodiments, the screen frame system 102 includes a screen frame 110 and a protective screen 112. In some embodiments, the screen frame 110 defines an opening 114 (e.g., a rectangular opening) and the protective screen 112 spans some or all of the opening 114. During use, the protective screen 112 may inhibit sports balls or other object frame passing through the area defined by the opening 114. For example, referring to
In some embodiments, the protective screen 112 includes a netting. For example, the protective screen 112 may be a flexible mesh style netting formed of nylon high density polyethylene (HDPE), rubber, or the like. The protective screen 112 may be secured to the screen frame 110, for example, by way of clips or similar fasteners. During use, the protective screen 112 may, for example, absorb the impacts of sports balls or other objects to inhibit the balls from hitting a person or other object protected by the field screen 100.
In some embodiments, the screen frame 110 is a rigid structure that supports the protective screen 112. For example, the screen frame 110 may be formed of one or more rigid screen frame members 120 that define an opening 114 and are capable of supporting a protective screen 112 that spans some or all of the opening 114. For example, in the illustrated embodiment, the screen frame 110 includes a screen frame upper member 122 (e.g., formed of individual screen frame upper members 122a-122d fastened to one another), a screen frame lower member 124 (e.g., formed of individual right and left screen frame lower members 124a and 124b), and screen frame arm members 128 (e.g., right and left screen frame arm members 128a and 128b). In some embodiments, the members of the screen frame 110 are formed of round or square tubing. For example, each of the screen frame members 120 may be formed of 1.5 inch×1.5 inch steel square tubing. In some embodiments, the respective members of the screen frame 110 are coupled to one another by way of welds or fasteners.
In some embodiments, the screen frame upper members 122 and the screen frame lower members 124 define the opening 114 that is covered by the protective screen 112. For example, in the illustrated embodiment, the screen frame upper member 122 and the screen frame lower member 124, together, define the rectangular shaped opening 114 that extends laterally and vertically (e.g., in the x-z plane) and that is covered by the protective screen 112.
In some embodiments, the screen frame arm members 128 facilitate coupling of the screen frame system 102 to the frame dampening system 106. For example, in the illustrated embodiment, each of the screen frame arm members 128 are coupled to a lower portion of the screen frame 110 and are oriented transverse to the planar opening 114 (e.g., oriented in the y direction) such that they define respective screen frame arms 128 (e.g., right and left screen frame arms 128a and 128b) that extend longitudinally from the lower portion of the screen frame 110, in front of the opening 114 and the protective screen 112 (e.g., in the positive y direction) and behind the opening 114 and the protective screen 112 (e.g., in the negative y direction). As described here, in some embodiments, resilient members of the frame dampening system 106 are disposed between the screen frame arm members 128 and complementary portions of the base frame system 104 to facilitate movement of the screen frame system 102 relative to the base frame system 104.
The base frame system 104 may be a structure that supports positioning of the screen frame system 102 above a supporting surface (e.g., above the ground). In some embodiments, the base frame system 104 includes base frame feet 140 (e.g., right and left base frame feet 140a and 140b). In some embodiments, the base frame feet 140 are rigid structures that are operable to support the screen frame 110 in a desired (e.g., upright/vertical) positon. For example, the base frame feet 140 may support the screen frame 110 in the illustrated upright/vertical positon that includes the upper portion of the screen frame 110 disposed in the x-z plane.
In some embodiments, the base frame feet 140 extend transverse to the screen frame 110 to support the screen frame 110 in an upright/vertical positon. For example, in the illustrated embodiments, each of the base frame feet 140 are located directly under the respective screen frame arms 128 and are oriented transverse to the planar opening 114 (e.g., oriented in the y direction) such that they define respective base frame feet 140 (e.g., right and left base frame feet 140a and 140b) that extend longitudinally in front of the opening 114 and the protective screen 112 (e.g., in the positive y direction) and behind the opening 114 and the protective screen 112 (e.g., in the negative y direction). The arrangement of the base frame feet 140 in front of and behind the screen frame 110 may facilitate holding of the screen frame 110 in a desired (e.g., upright/vertical) positon and inhibit the screen frame 110 from falling forward or backward while not in use or in the event the screen frame 110 is struck by a ball or other object.
Each of the base frame feet 140 may be formed of one or more rigid base frame members 142 that define a footing that is capable of supporting the screen frame 110 in a desired positon. For example, in the illustrated embodiments of
The longitudinal extension of the base frame members 142 in front of and behind the laterally oriented screen frame 110 may facilitate holding of the screen frame 110 in a desired positon, such as the generally upright/vertical (or “standing”) position, and inhibit the screen frame 110 from falling forward or backward in the event the screen frame 110 is struck by a ball or other object. The lateral extension of the wing members 146 from the base frame foot members 144 may inhibit each of the base frame feet 140 from “rolling over” sideways (e.g., rotating about a longitudinal axis of the associated base frame foot member 144), such as during assembly of the field screen 100 while the base frame feet 140 are not held in positon by the screen frame 110, and may enhance the general support and stability of the base frame foot members 144 and the assembled field screen 100. As described here, in some embodiments, resilient members 150 of the frame dampening system 106 are disposed between base frame foot members 144 and complementary portions of the screen frame system 102 to facilitate movement of the screen frame system 102 relative to the base frame system 104.
The frame dampening system 106 may facilitate movement (e.g., pivoting) of the screen frame system 102 relative to the base frame system 104. In some embodiments, the frame dampening system 106 includes one or more resilient members 150 that are disposed between the screen frame system 102 and the base frame system 104. Each resilient member 150 may be coupled to a portion of the screen frame system 102 and a complementary portion of the base frame system 104 such that the screen frame system 102 is coupled to the base frame system 104 by way of the resilient members 150. For example, one or more resilient members 150 may be disposed between (and be coupled to) some or all of the following pairs of frame portions: (1) a front portion 152 of the right screen frame arm 128a and a front portion 154 of the base frame foot member 144 of the right base frame foot 140a; (2) a front portion 152 of the left screen frame arm 128b and a front portion 154 of the base frame foot member 144 of the left base frame foot 140b; (3) a back portion 156 of the right screen frame arm 128a and a back portion 158 of the base frame foot member 144 of the right base frame foot 140a; and (4) a back portion 156 of the left screen frame arm 128b and a back portion 158 of the base frame foot member 144 of the left base frame foot 140b.
For example, referring to the detailed view of
During use, the resilient members 150 may provide a restoring force in response to being deformed. For example, in the event the front portion 152 of the right screen frame arm 128a moves upward/away from the front portion 154 of the base frame foot member 144 of the right base frame foot 140a (as indicated by arrow 170), the “front-right” resilient member 150 may be placed in tension and, in turn, generate a restoring force (as indicated by arrow 172) that pulls the front portion 152 of the right screen frame arm 128a downward/toward the front portion 154 of the base frame foot member 144 of the right base frame foot 140a. In the event the back portion 156 of the right screen frame arm 128a moves downward/toward the back portion 158 of the base frame foot member 144 of the right base frame foot 140a (as indicated by arrow 174), the “back-right” resilient member 150 may be placed in compression and, in turn, generate a restoring force (as indicated by arrow 176) that pushes the back portion 156 of the right screen frame arm 128a upward/away from the front portion 154 of the base frame foot member 144 of the right base frame foot 140a. Accordingly, in some embodiments, the front and back resilient members 150 act in coordination to facilitate and regulate movement (e.g., pivoting) of the screen frame 110 relative to the base frame system 104 and to provide a restoring force that urges (or “biases”) the screen frame 110 to return to a given position. As an example, in the event the screen frame 110 is held in a standing position (e.g., a generally vertical/upright orientation, as shown) and a ball or other object traveling in the direction of arrow 180 (e.g., in the negative y direction) strikes the front side of the screen frame system 102 (e.g., a front side of the screen frame 110 or a front side of the protective screen 112), the impact may generate a force/torque on the screen frame (as indicated by arrow 182) that causes tensioning of the “front-right” resilient member 150 (as indicated by arrow 170) and compression of the “back-right” resilient member 150 (as indicated by arrow 174). As a result, the “front-right” resilient member 150 (now in tension) may generate a restoring force (as indicated by arrow 172) that pulls the front portion 152 of the right screen frame arm 128a downward/toward the front portion 154 of the base frame foot member 144 of the right base frame foot 140a, and the “back-right” resilient member 150 (now in compression) may generate a restoring force (as indicated by arrow 176) that pushes the back portion 156 of the right screen frame arm 128a upward/away from the back portion 158 of the base frame foot member 144 of the right base frame foot 140a. The resulting deformation (e.g., the elongation and compression) of the resilient members 150 may cause the screen frame 110 (and the protective screen 112) to pivot (or “tilt”) backward relative to the base frame system 104. The movement may include pivoting movement of the screen frame 110 (and the protective screen 112) about a lateral oriented pivot axis 184 (e.g., an axis oriented in the x direction) (as indicated by arrow 186). In some embodiments, the deformation may include an element of horizontal shear that causes longitudinal movement of the screen frame 110 (and the protective screen 112) (e.g., in the negative y direction) (as indicated by arrow 188) relative to the base frame system 104. Further, the restoring forces provided by the deformation of the resilient members 150 may urge (or “bias”) the screen frame 110 (and the protective screen 112) back to the vertical/upright orientation.
In some embodiments, the screen frame arms 128 include stop members 190 that are configured to limit movement of the screen frame 110 (and the protective screen 112). For example, a stop members 190 may include a member that extend downward from a respective screen frame arm 128 and that is positioned to engage a complementary portion of the base frame foot member 144 to limit movement of the screen frame 110 (and the protective screen 112) relative to the base frame system 104.
In some embodiments, the resilient members 150 are longitudinally offset from one another by a distance (D1) in the range of about 6-24 inches (e.g., D1 may be about 12 inches) (see, e.g.,
Although a right side of the field screen 100 is depicted and described with regard to
Embodiments may employ alternative components to those described with regard to
In some embodiments, the described base frame feet 140 employ one or more recesses into which the resilient members 150 are disposed and mounted. For example,
In some embodiments, the recesses 200 provide for a lower surface of a resilient member 200 being disposed below an upper surface of the base frame feet 140. For example, in the illustrated embodiments of
Similar to the other described embodiments (and as illustrated in
In some embodiments, the resilient members are located at positions similar those described with regard to other embodiments (e.g., D1 is equal to or about 12 inches, D2 and/or D3 are equal to or about 6 inches), and the feet 144 may be similarly sized (e.g., L1 is equal to or about 54 inches). In some embodiments, the cutouts 206 have a length (D4) that is about the same or greater than the length (L2) of the resilient member 150 (e.g., D4 is equal to or about 2.25 inches) and the cutouts 206 have a width (D5) that is about the same or greater than the major external diameter (Dmaj) of the resilient member 150 (e.g., D5 is equal to or about 3 inches) (see, e.g., FIG. 5D). In some embodiments, the rectangular tubing 201 may have a height (H) of about 0.5-2 inches (e.g., H is equal to or about 1 inch), a width (W) of about 2-4 inches (e.g., W is equal to or about 3 inches) and a wall thickness (t) equal to or about 0.08 inches (see, e.g.,
Although a right side of the field screen 100 is depicted and described with regard to
As used throughout this application, the word “may” is used in a permissive sense (e.g., meaning having the potential to), rather than the mandatory sense (e.g., meaning must). The words “include,” “including,” and “includes” mean including, but not limited to. As used throughout this application, the singular forms “a”, “an,” and “the” include plural referents unless the content clearly indicates otherwise. Thus, for example, reference to “an element” may include a combination of two or more elements. As used throughout this application, the term “or” is used in an inclusive sense, unless indicated otherwise. That is, a description of an element including A, B or C may refer to the element including A, B, and C, A and B, A and C, B and C, or A, B and C.
