            <link>http://www.freepatentsonline.com/7677995.html</link>
            <description><![CDATA[An expandable arrow broadhead used for releasable attachment to one end of a hollow arrow shaft. The broadhead includes a sliding shaft with a pointed tip and tip base having two or more of cutting blades mounted thereon. Each of the blades includes an outer cutting edge and an inner edge with a beveled cam surface and locking notch therein. A portion of the sliding shaft is slidably received inside a hollow collar. The collar is attached to a sliding shaft housing. The sliding shaft housing is attached to an arrow shaft insert. The arrow shaft insert is adapted for receipt inside one end of the arrow shaft. In a retracted position, the blades are disposed next to and parallel to the length of the sliding shaft. When the pointed tip engages a target, the sliding shaft moves inwardly and rearwardly sliding inside the collar and inside a sliding shaft bore hole in the sliding shaft housing. As the sliding shaft moves rearwardly, the beveled cam surface of the blades engages a portion of the collar, which moves the blades outwardly with locking notch securing the blades in an extended position.]]></description>

            <title><![CDATA[Tennis backboard]]></title>
            <link>http://www.freepatentsonline.com/7677993.html</link>
            <description><![CDATA[The invention provides a new tennis backboard design. The backboard includes a firm backing layer underlying a soft deadening layer. The rebound of a tennis ball from the backboard is reduced as compared to rebound from a rigid hard-surface backboard. This allows a player to stand fairly close to the backboard, which reduces misses. The player can stand fairly close and hit balls hard against the backboard. Because the rebound is reduced, the ball simply bounces back softly and easily to the player, allowing the player to hit hard again from a fairly short distance. Thus, long rallies without missing are easily achieved. Since the bounce is reduced, the player can stand closer to the backboard, and therefore the backboard can be smaller than conventional backboards without the player missing the backboard. This allows the backboard to be light, portable, and easily stored. Because of the addition of a soft deadening layer, the firm backing layer of the backboard can also be thin and made of lighter and weaker material than a conventional backboard, reducing the weight of the backboard.]]></description>

            <description><![CDATA[A baseball bat swing trainer attaches to a baseball bat and is configured to train a batter to maintain a level swing. The baseball bat swing trainer is attachable to a horizontal structure that is over the head of the batter and to a baseball bat. The baseball bat swing trainer includes a single-unit line controller, a line, and a baseball bat coupling connected to the line. The line controller is configured to vary and fix a working length of line defined as extending from the line controller to the baseball bat. The line may be varied in length, a working length, in order to accommodate different size batters. The line controller is configured to keep and release excess line. The coupling is secured onto the baseball bat at a location taken from a handle of the baseball bat that is approximately 50% of an overall length of the baseball bat.]]></description>

            <description><![CDATA[A golf club stand to prevent the forgetting of spare clubs by standing them upright in a noticeable position when they are carried to a shot but are not used. The club stand folds into a compact configuration resembling a golf club for convenient carrying in a gold bag when not in use. The device generally comprises a shaft with a grip-handle similar to that of a golf club, and a sharp point at the distal end of the shaft to allow the club to be inserted into the ground. In addition, a dual-pivot arm is secured to the upper end of the shaft for supporting the handle(s) of one or more golf clubs. The ends of the dual-pivot arm are formed as cradles and may be pivoted into a transverse in-line position relative to the shaft. When the shaft is inserted vertically into the ground and the cradle ends of the pivot arm are horizontally disposed, a plurality of clubs may be supported by the club stand, the head of each club resting on the ground and the handle of all clubs supported by the transverse arm in one of the cradle ends. This keeps the clubs off the ground and highly visible. When they are standing upright in plain view they are harder to overlook and forget.]]></description>

            <description><![CDATA[A cue stick includes a shaft, a solid force-transmitting pipe, a butt, and a wooden fitting portion. This shaft includes a tip, a solid portion, a hollow portion and a connecting portion. This solid force-transmitting pipe contains an inner space. The butt connects with the shaft. The wooden fitting portion fills in the inner space. The density of the wooden fitting portion is between 80% and 120% of the density of the solid portion. So, the weight and size are nearly same as the ones of a traditional solid wood cue stick. The total weight of the cue stick is proper. Its internal force transmission is evenly distributed. Plus, the feedback feeling for striking the cue ball is excellent.]]></description>
