A variety of sports training devices have been developed to enhance athlete performance. Many sports require specific skills and abilities and a variety of training devices have been used to facilitate drills and practice exercises that facilitate developing such skills and abilities.
The game of hockey requires accurate passing between players. It is useful for a player to develop the ability to deliver accurate passes and to competently handle passes provided to that player. One type of device that has been proposed to facilitate passing drills includes rubber band-like straps supported at two ends to provide a spring-like surface against which a hockey puck may be directed and subsequently received from.
While these devices may be of some use, they suffer from various drawbacks and limitations. For example, the rubber band-like straps typically do not mimic the behavior of a passed puck during real game situations. Additionally, there tends to be a limited area where the puck needs to impact the strap or the rebounding effect is significantly different. For example, near the ends of the strap much less of a rebound effect occurs compared to when the puck impacts the center of the strap. This difference in rebound behavior can be annoying and hinder the progress of passing drills.
Another skill that is required in the game of hockey is for a goaltender to be able to react to puck deflections and so-called one-timer shots immediately after the puck has been passed between opposing players. When players are not available for conducting such drills for a goaltender, goaltending coaches have tried to use the dasher boards as a surface against which to deflect the puck toward the goaltender in a fashion that mimics a deflection or one-timer shot during a game situation. The rigid dasher board provides a surface from which the puck can rebound but the behavior does not simulate real game conditions.
An illustrative example embodiment of an ice hockey puck rebounder includes a rigid base with ends that establish a base width. The rigid base includes side faces between the ends that establish a base length that is greater than the width. The side faces of the base have a height that is less than the length. At least one resilient member has a first surface secured to at least one of the side faces of the base. The resilient member has a thickness in a direction parallel to the base width between the first surface and a second surface facing in an opposite direction from the first surface. The resilient member is received against and supported by the side face of the base along its entire length. The resilient member has a durometer between 50 and 60. The second surface presents a rebound surface for being contacted by an ice hockey puck. The resilient member consistently, resiliently deflects an ice hockey puck away from the resilient member.
An illustrative example method of making a rebound device includes establishing a base. The base is powder coated and then some of the coating on at least a portion of at least one side face is roughened. An adhesive enhancer is applied to the roughened portion. The applied enhancer is then roughened to disrupt the outer layer or surface of the adhesive enhancer. An adhesive is then applied to at least one of the roughened portion or the resilient member. The resilient member is then secured to the roughened portion of the base by the adhesive.
The various features and advantages of at least one disclosed embodiment will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.
The device 20 includes at least one resilient member 40 that is secured to a side face 28 of the base 22. The illustrated example includes a resilient member 40 on each of the side faces 28. The resilient members 40 have a thickness T in a direction parallel to the width W as visible in
The second side 44 presents a rebound surface for resiliently deflecting an object away from the device 20.
As can be appreciated from
The resilient members 40 in the illustrated embodiment comprise a rubber-based material. Natural rubber or gum rubber is used for some embodiments. A durometer of approximately 55 provides a desirable rebound effect. Durometers between 48 and 60 are useful. Depending on the selected material, a resilient member 40 having a durometer of 45 or less may be too soft and may not provide a sufficient snap-back effect when a puck rebounds off the resilient member. Additionally, a softer resilient member may tend to break down too quickly especially with regular or continuous use. A durometer over 60 tends to leave the resilient members 40 too rigid so that a desired rebound effect is not easily or consistently achieved. In an example embodiment, the material chosen for the resilient members comprises a commercially available rubber having a 55 durometer rating. Some commercially available rubber materials having a 55 durometer rating tend to have an actual durometer between 50 and 60.
The resilient members 40 also have a first height H1 that is less than a second height H2 of the side faces 28 as shown in
One feature of the illustrated embodiment is that the end faces 26 include a plurality of teeth 54 that resist movement of the base 22 relative to the ice surface upon which the device 20 is placed. The teeth 54 in this example include some oriented at a first oblique angle relative to the width dimension of the base 22 and others at a second, different oblique angle relative to the width dimension. Differently oriented teeth facilitate a stable placement of the device 20 on the ice. The teeth 54 and the mass of the device 20 are effective at keeping the device 20 in a desired position and orientation on the ice throughout most drills for many different skill levels of play.
Another embodiment does not include teeth on the underside of the base 22. Instead, a plurality of rubber or polymer pads are secured to the bottom 32 of the base 22. The pads resist movement of the device along a floor surface to maintain a desired placement of the device 20. Such pads can also protect a floor surface against damage that otherwise might result from contact with the metal base 22.
Another feature of the example embodiment is that the end faces 26 each include at least one opening 56 (best seen in
The illustrated device 20 also includes a handle 58 that is secured to the top face 30. The handle 58 facilitates carrying the device 20 to a desired location and placing it in a selected orientation on the ice.
An adhesive enhancer is applied to the roughened portion(s) at 66. After the adhesive enhancer is applied, it is roughened at 68 to at least slightly roughen the outer layer or outer surface of the enhancer without removing all of the enhancer. At 70, adhesive is applied to at least one of the prepared portion of the side face(s) 28 and the first side(s) 42 of a resilient member 40. The final step represented at 72 in
The adhesive in one example embodiment comprises a urethane two-part epoxy adhesive. One such adhesive is known as Lord 7542 Urethane Adhesive and is commercially available from Lord Corporation. The adhesive enhancer in one example is a pretreat rubber adhesive enhancer available from Lord Corporation.
