    Abstract: A tool holder system for conveniently supporting one or more tools upon a pegboard structure or a wall. The tool holder system includes a support structure having a plurality of receiver openings formed for receiving a tool, a plurality of recessed portions formed into a rear portion of the support structure, a plurality of fastener slots for securing the support structure to a wall, and a clip member formed to catchably engage within said recessed portions for securing the support structure to a pegboard. The clip member is comprised of a body, an upper hook and a lower hook wherein the hooks catchably engage apertures within the pegboard. The lower hook includes a lip for catchably engaging one of the apertures within the pegboard thereby preventing accidental removal of the clip member. Each clip member further includes an upper slot for receiving a portion of the support structure and a lower slot for receiving a lower cross member within the recessed portions.

  • Patent number: 6286777
    Abstract: An extension cord storage and dispensing system for conveniently dispensing, accumulating and storing various lengths of one or more extension cords without significant entanglement occurring. The inventive device includes a frame having a first end, a middle portion and a second end, the frame includes a first spool and a second spool, a U-shaped cutout extending into a side of the frame, a handle attached to the frame opposite of the U-shaped cutout, and a pair of knobs rotatably attached to the first end and the second end of the frame. The pair of knobs are held by the user while the frame freely rotates upon the knobs thereby allowing the extension cord or other elongated object to be easily dispensed. When accumulating the extension cord after utilization, the user positions the inner portion of their elbow within the U-shaped cutout and grasps the handle with their hand thereby providing adequate leverage for the user while winding the extension cord about one of the spools.

  • Patent number: 6142405
    Abstract: An extension cord storage and dispensing system for conveniently storing and dispensing an elongated extension cord of various lengths without entanglement and without requiring the unwrapping of the entire length of extension cord to effectively utilize both ends. The inventive device includes a second spool, a first spool and a handle. The second spool and the first spool preferably have a flat profile for convenient storage. The first spool receives a longer length of the extension cord while the second spool receives a shorter length of the extension cord that is commonly needed thereby separating the shorter length of the extension cord constantly dispensed and stored from the longer length. The first spool comprises a support base, and a vertical frame having a pair of opposing side members receiving the longer portion of the extension cord or other elongated object. The second spool comprises a first arm and a second arm.

  • Patent number: 5566934
    Abstract: A baseball trainer includes a target apparatus set at a predetermined distance from a practicing ballplayer. The target apparatus includes a plurality of panels for indicating a "strike" or a "ball" which indication is communicated to a microcomputer in a console adjacent to the practicing player. The target apparatus is associated with an adjacent catching apparatus and ball return apparatus for returning the ball to the player. The player pitches from a pitching rubber which includes a switch for providing a start signal when the player shifts the weight off of his back foot at the instant the ball is pitched toward the target apparatus. The start time, together with a stop time generated by the "strike" or "ball" panels, can be used by the microcomputer to generate an elapsed time which together with the known distance is used to calculate the speed of the pitch and which is then audibly reported to the practicing player.
