SPORTS TARGET DEVICE FEATURING ELASTIC RETURN MECHANISM

Abstract

A target assembly that is configured to withstand high-velocity impact from a projectile. These configurations may comprise elastic members, or “bungee” cords, that generate elastic forces to return the target assembly to its orientation prior to impact. The bungee cords are less likely to undergo inelastic deformation; so these components afford the target assembly with longer life or longevity under heavy duty cycles.

DETAILED DESCRIPTION

[0012] Excellence in athletics is due in large part to practice. Athletes spend countless hours at home or at practice facilities to hone their skills. Often, they perform repetitive drills to develop proper mechanics or muscle memory that translates into success in game play. Many products are available to assist in this endeavor. These products may include targets to improve shot or pass accuracy. In use, athletes throw or direct a projectile, like a ball or puck, over-and-over again at the targets.

[0013] Targets and target assemblies according to this disclosure may find use in these products. These targets employ a design that permits movement between an initial orientation and an impacted orientation. The design incorporates a return mechanism that repeatedly returns the target to its initial position, though, even after multiple high-velocity impacts. This mechanism may leverage elastic or spring-like devices for this purpose. These devices may react (e.g., deform) to movement of the target from its initial orientation. The deformation may generate elastic or spring forces that act in opposition to the direction of movement and return the target to its initial orientation Other embodiments are within the scope of the subject matter herein.

[0014] FIG. 1 depicts a perspective view from the front an example of a target 100. This example is shown in position on a rigid member 102, typically a stiff, metal rod or tube made from steel or aluminum. This tube may incorporate into a frame that can attach to a sports goal. The target 100 may have an impact body 104 that bears impact from the projectile. The impact body 104 may have several parts (e.g., a first part 106 and a second part 108). The parts 106, 108 may affix to one another with adhesive or fasteners, like screws or bolts. The first part 106 may embody a flat or thin panel that is square or circular, although other shapes may suffice as well. Material(s) for the flat panel 106 should have properties to withstand high-velocity impacts. Stiff foam or rubber may work for this purpose, but other materials (alone or in combination or composite) may work so long as they don't shatter or break at impact. The second part 108 may embody a rigid strip that attaches on a forward or impact face of the foam panel 106, which is effective to reinforce the foam panel 106. Plastics, like ABS (or Acrylonitrile Butadiene Styrene), may be useful for this purpose. The plastic strip 108 may cover only a portion of the surface area of the impact face of the foam panel 106. In one implementation, it may extend along all or part of an edge on the foam panel 106. This edge may reside proximate the frame member 102 with the target 100 resident on the frame. As shown, the plastic strip 108 may extend over the edge so part of it overlaps with the frame member 102.

[0015] As also shown, lateral openings 110 may penetrate through one or both parts 106, 108. The openings 110 may embody through-holes with centers that closely align with one another on a lateral plane P. The holes 110 may be spaced laterally apart from one another across the impact face of the parts 106, 108 as well. This example has two sets of holes (A, B), one each on either side of the centerline CL of the parts 106, 108. But the device may benefit from more or less of the holes 110 as desired. In one implementation, the holes 110 may receive tension members 112 to create a tension pre-load that biases the impact body 104 in a first or initial orientation (shown here in FIG. 1).

[0016] FIG. 2 depicts an elevation view of an example of the tension members 112. This example includes an elastic cord 114. Preference may be given to materials for the elastic cords 112 that can elongate in response to movement of the impact body 104 and then return to their original length. These materials may include “bungee” or shock cord, or like elastic materials (e.g., rubber). The bungee cord 114 may include an elongate body 116 that terminates at a pair of ends 118, each with a crimped ring 120 disposed thereon. When assembled into the tension member 112, the elongate body 116 may fold (in half) to insert into a retaining member 122, for example, a flat washer or ring made of metal or hard plastic. This arrangement forms a closed loop 124 because the flat washer 122 may have an inner diameter that retains the crimped rings 118 on one side. Dimensions for the inner diameter can maintain this location of the crimped rings 118 when pulling or loading the closed loop 124 (as indicated by the arrow L).

[0017] FIG. 3 depicts an elevation view of the backside of the target 100 of FIG. 1. The closed loop 124 may insert through the holes 110 from the backside of the foam panel 106. The flat washer 122 acts as a stop so that the closed loop 124 can stretch to extend or wrap over the frame member 102 from the front side to the backside of the foam panel 106. In one implementation, the closed loop 124 can loop around the flat washer 122. This arrangement creates the tension pre-load in each of the tension members 112. The pre-load may correspond with the length of the bungee cords 114 and the location of the holes 110 relative to the frame member 102, among other factors.

[0018] As noted above, the impact body 104 may be configured to change orientation relative to the frame member 102 in response to impact from the projectile. These configurations may use a joint 126 to couple the impact body 104 to the frame member 102. The joint 126 may embody devices that provide sufficient degrees-of-freedom to allow for movement of the impact body 104 relative to the frame member 102. The device here has one degree-of-freedom for the impact body 104 to effectively “swing” relative to the frame member 102. In one implementation, the device may use a hinge 128 with several components, like a pin joint 130 that connects corresponding leaves 132, one each that mounts to the frame member 102 and the backside of the foam panel 106 (with fasteners F.sub.1 and F.sub.2). The pin joint 130 stabilizes the impact body 104 so that it does not twist or turn in response to “off-center” contact by the projectile.

[0019] FIG. 4 depicts an elevation view of another example of the retaining member 122. This example may embody a ball 134 (typically metal or plastic) with a central opening 136, for example, a counter-bored through-hole. Ends 118 of the elongate body 116 may be knotted and reside in the counter-bore. This arrangement also forms a closed loop 124 as the knotted ends 118 prevent the elongate body 116 from pulling out of the ball 134 under load L (FIG. 2). When assembled, the closed loop 124 engages with the ball 134 on the backside of the foam panel 106.

[0020] FIG. 5 depicts a plan view of the top of the target 100 of FIG. 1. The target 100 is shown in a second or impacted orientation that might result from impact by the projectile. In use, movement of the impact body 104 to the impacted orientation may stretch the bungee cords 114, generating an internal elastic force (or elasticity) that returns the impact body 104 to its initial orientation. The plastic strip 108 may serve several roles as well. First, it may press against the closed loop 124 (at C) to increase the elastic force. It may also prevent “over-rotation” of the impact body 104, contacting the frame member 102 to ensure that the impact body 104 resides in its initial orientation (FIG. 1), which is essentially planar with the outwardly facing surface of the frame member 102. Further, the plastic strip 108 may protect the hinge 128 from impact by the projectile to avoid damage from high-velocity shots.

[0021] The target 100 may benefit from a sensing mechanism 138 that can register the change in orientation. The sensing mechanism 138 may embody devices that do not require contact between sensor and emitter. These non-contact devices may deploy various modalities, including optical, ultrasonic, or magnetics; however, other types of sensors may be useful as well. In one implementation, the device may include a magnetic sensor 140 (on the frame member 102) that detects proximity of a magnetic field from a magnet 142 (on the foam panel 106). Movement of the impact body 104 from the initial orientation (FIG. 1) to the impacted orientation may separate the magnet 142 from the sensor 140 enough to break continuity in the magnetic sensor 140 (or cause some other response as desired or designed).

[0022] FIG. 6 depicts a perspective view of one application of the target 100 of FIG. 1. This application includes a large frame 144 with a number of frame members 102. The frame 144 may fit onto a lacrosse goal or hockey goal, but dimensions may vary as desired. As discussed herein, the frame 144 accommodates several of the targets 100, disposed on the frame members 102. The tension members 112 maintain each of the targets 100 in their initial orientation. Impact by the projectile on the individual targets 100 will cause it to move to its impacted orientation. The tension members 112 will return the impacted target 100 back to its initial orientation almost immediately thereafter.

[0023] In view of the foregoing, the embodiments herein are meant to withstand long-term high-velocity impacts from projectiles, like hockey pucks, lacrosse balls, and baseballs. The resilient, elastic return mechanism is useful because it does not undergo inelastic deformation, which may over-time adversely affect springs (e.g., wound coil springs). This improvement results in a target (or target assembly) with better longevity. This feature can reduce costs and labor for manufacturers because these targets are less likely to require repair or replacement parts, if at all.
