Description

BACKGROUND

In many sports and other activities, the ability to provide a target is of paramount importance for learning and training. For example, many devices exist that provide a target against or through which a person can throw a ball. Many of these devices, however, do not provide a target zone that is positioned and suspended in a particular location in free space, and which yield for an object that makes contact with the device so that the target zone maintains its shape and position.
For instance, many target devices will change the trajectory of an object if contact is made. As such, these devices really cannot provide a true and effective target zone of desired dimensions, which can be used in realistic situations of the associated sport or activity. What is needed is an apparatus and system for providing a target zone in free space and which can be employed in realistic sports situations.

SUMMARY

An apparatus and method for providing a target zone for an object in motion is disclosed. In one aspect, an apparatus includes an inelastic strand that defines a perimeter of a zone, and at least two elastic strands. Each elastic strand is connected to a point along the inelastic strand, such that when biased outward from the inelastic strand, the at least two elastic strands form the zone into a predetermined shape.
In another aspect, a system for providing a target zone for an object in motion includes an inelastic strand that defines a perimeter of a zone, and at least two elastic strands. Each elastic strand is connected to a point along the inelastic strand, such that when biased outward from the inelastic strand, the at least two elastic strands form the zone into a predetermined shape. The system further includes a support having an attachment mechanism to which the at least two elastic strands can be connected to suspend the zone at a predetermined height.
The support can include two support structures. Each support structures may be formed as a post connected to a base for placement on a substantially planar surface. The post can be telescopically arranged to a particular desired height.
In yet another aspect, a method for providing a target zone for an object in motion, includes defining a perimeter of a zone with an inelastic strand, and connecting at least two elastic strands to respective points along the inelastic strand, such that when biased outward from the inelastic strand, the at least two elastic strands form the zone into a predetermined shape.
The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

FIG. 1 shows an embodiment of an apparatus 100 for providing a target zone for an object in motion. The apparatus 100 includes an inelastic strand 102 that forms a perimeter of a zone 101. The inelastic strand 102 can be any string, cord, rope, thread or twine that has a minimal amount of elasticity, and can be formed of any natural or synthetic textile materials. In one exemplary embodiment, the inelastic strand 102 is formed of nylon twine.
The apparatus 100 further includes at least two elastic strands 104, and preferably at least four elastic strands 104. Each elastic strand is connected to a point 103 along the inelastic strand 102, such that, when the at least two elastic strands 104 are stretched outward from the inelastic strand 102 in a direction parallel to a central axis of each elastic strand 104, the zone 101 is formed into a shape 106 of predetermined dimensions. Each elastic strand 104 can be any string, cord, rope, thread or twine that has elasticity. Most or all of the energy of an object that grazes or touches the inelastic strand 102 is absorbed by the elasticity of one or more of the elastic strands 104 such that the trajectory of the object is not materially impeded.
The shape 106 is preferably rectangular, to provide a rectangular target space 101, but can also be triangular or any other polygonal shape. In an embodiment, the dimensions of the shape 106 in a rectangular form range from 10 to 30 inches in height by 10 to 30 inches in width. In a preferred exemplary embodiment, the dimensions of the shape 106 in a rectangular form are around 24 inches in height by around 17 inches in width, to correspond approximately with a baseball strike zone. The baseball strike zone is that area over home plate, the upper limit of which is a horizontal line at the midpoint between the top of a batter's shoulders and the top of the batter's uniform pants, and the lower level is a line at the hollow beneath the batter's knee cap. The baseball strike zone is determined from the batter's stance as the batter is prepared to swing at a pitched ball, which the apparatus 100 allows in a realistic practice scenario.
In an exemplary embodiment, the dimensions of the zone 101 are configurable to allow dimensions of any size. In this example, the connection point of at least one elastic strand 104 can be moved or changed to change the associated dimensions of the shape 106 of the zone 101. In an exemplary embodiment, the inelastic strand 102 has a color that is different from the color of the elastic strands 104. Preferably, the color of the inelastic strand 102 contrasts with the color of the elastic strands 104 in order for the inelastic strand 102 to stand out while being suspended in the shape 106 of the zone 101.
As depicted in FIG. 2, the apparatus 100 can be integrated into a system 110 that includes a support structure 112 to which one or more of the elastic strands 104 can be attached to suspend the inelastic strand 102 in the shape 106 of the zone 101. In a preferred embodiment, support structure 112 includes two supports 113, and the system 110 includes four elastic strands 104 connected in pairs to the two supports 113.
In an exemplary embodiment, each support 112 includes a post 116 connected to and secured in an upright position by a base 114. The post 116 can be telescopic, i.e. formed of two or more telescoping pieces, for adjustment to any range of height. The base 114 is sufficiently heavy and of sufficient size to inhibit substantial bending of the post 116 when the apparatus 100 is suspended in a target-providing mode. The base 114 and/or post 116 can be made of wood, plastic, or metal, or any other suitably rigid and/or heavy supportive material.
Each post 116 can include at least one hook, eye bolt, strap, aperture, or other connecting mechanism to which at least one elastic strand 104 can attach. The arrangement and connection between the support 112 and at least one elastic strand 104 provides the desired length, position and/or tension of the elastic strand 104. In an embodiment, the post 116 includes a retraction mechanism to allow the elastic strand 104 to be extendable from the post 116. Alternatively, the elastic strand 104 can be wound around or unwound from the post 116 to a desired length or tension.
FIGS. 3A and 3B show several examples of a mechanism for attaching an elastic strand 104 to a support structure, such as a fence, a wall, a post, or the support 112. The elastic strand 104 can be attached to a hook 120, as shown in FIG. 3A, or to a velcro™ strap 112, as shown in FIG. 3B.
FIGS. 4A and 4B show several examples of a mechanism for connecting an elastic strand 104 to a point 103 of an inelastic strand 102. As illustrated in FIG. 4A, the inelastic strand 102 can be looped and secured at the point 103 to define a comer to which the elastic strand 104 can be attached. As illustrated in FIG. 4B, the elastic strand 104 can be connected to the inelastic strand 102 by a knot at the point 103. Other mechanisms for connecting the elastic strand 104 to the inelastic strand 102 can also be used.
FIG. 5 shows an alternative embodiment of a system 200 that includes an apparatus 202 for providing a target zone in free space, coupled to two support structures 204. The apparatus 202 includes four elastic strands 206 formed of an inelastic cord that is formed into a corkscrew form, where the loops of the corkscrew are biased to converge but which will yield to expand apart when the strand 206 is stretched or when an object impacts with the strand 206. Each elastic strand 206 is coupled at one end to a spring-loaded clip 208 that has at least one first aperture 209 that can be opened and closed, and which is closed in a default position by a spring in the clip 208.
Each elastic strand 206 is coupled at an opposite end to an inelastic strand 210 that is formed into a shape 211 of predetermined dimensions. The shape 211 is preferably rectangular, but can also be triangular or any other polygonal shape. In an alternative preferred embodiment, the dimensions of the shape 211 can be adjustable to correspond with a baseball strike zone, substantially as described above. The inelastic strand 210 has a color that is different from the color of the elastic strands 206. Preferably, the color of the inelastic strand 210 contrasts with the color of the elastic strands 206.
The apparatus 202 can be connected to a fence, a post, a wall or any other stationary structure. Alternatively, the system 200 also includes two support structures 204 to which the apparatus 202 can be connected. Each support structure 204 includes a base 220 for being placed on a substantially planar surface, and an adjustable post comprising a lower post member 222 and an upper post member 224 that is slidably mated with the lower post member 222. In an embodiment, the lower post member 222 and the upper post member 224 are cylindrical, and the upper post member 224 fits within the lower post member 222 in a telescoping arrangement. One or more holes 228 are provided in the lower post member 222 to receive a depressible pin (not shown) in the upper post member 224 to secure the post members in an arrangement for a desired height that is selectable from two or more predetermined height arrangements.
The upper post members 224 include an attachment mechanism 226 to which an elastic strand 206 of the apparatus 202 can be coupled. An attachment mechanism 226 can also be provided by the lower post member 222 or even on the base 220. In an exemplary embodiment, the attachment mechanism is an eye bolt, but can also be a ring, a hook, or other attachment device.
FIG. 6 illustrates one example of a spring-loaded clip 208 having at least one first aperture 209 that can be opened and closed. The clip 208 may also include a second aperture 230 for attaching to an interface 232 connected to the elastic strand 206. In one embodiment, the second aperture 230 is closed, and adapted to rotate relative to the rest of the clip 208.
Although a few embodiments have been described in detail above, other modifications are possible. Other embodiments may be within the scope of the following claims.
