  • Publication number: 20200101347
    Abstract: An exercise machine. The machine comprises a frame with front and rear upper support beams. Guide rails span between the two support beams and are connected thereto. Right and left handles are configured to slide back and forth along the length of the guide rails between the front and rear support beams. During operation of the machine, a user grabs the handles and moves them back and forth in a swinging motion that mimics traversing a set of monkey bars. The guide rails may be arranged in a non-parallel configuration to provide a more natural path for the user's hands during operation and to reduce unwanted stress on the user's shoulders by limiting handle movement along the path to accommodate a more comfortable range of motion.

  • Patent number: 7094185
    Abstract: A self-spotting system for free weights enables the constructive use of such free weights without the need for a spotter. Using a free weight holder sliding along a rail, an adjacent free weight support provides and determines the lowermost travel of the associated free weight. In alternative embodiments, a parallelogram design for the free weight holder is set forth as well as a handle system which may optionally incorporate free weights and allow the use of the self-spotting system for single weights in conjunction with weights coupled to the handle system by a line or cable. Additionally, weight bar restraining and locking systems are set forth which provide secure means by which weightlifting bars can be secured into place, lowering the risk of slippage, dropping and the associated injury and damage that may occur when weights slip or fall.

  • Publication number: 20050209070
    Abstract: A self-spotting free weight device wherein the free weights are retained by arms which are pivotal in the horizontal plane of the arm and wherein the supporting arms are also pivotally supported from a support structure such that they move in a plane perpendicular to the plane in which the free weights may be moved.

  • Publication number: 20030134721
    Abstract: An exercise machine provides self spotting for free weights while providing full range motion for the available articulation associated with the free weight. A basic framework provides structure on which a self-spotting mechanism can be slidably attached. Rearwardly-extending arm or arms coupled with articulating engagement of a free weight holder allows the free weights to enjoy a wide range of motion. A horizontal stop provides a rest, abutment, or stop upon which the free weight holders may rest in order to perform self-spotting for the weightlifter. In alternative embodiments of the free weight holders, rearwardly-extending members may either be rigidly affixed to a free weight engager or telescope within the free weight engager itself. In an alternative embodiment of the self-spotting system of the present invention, rear opposing arms may form part of the articulating member allowing forward and backward lateral travel of the free weights.

  • Patent number: 6276990
    Abstract: A unique table saw having a roller mounted table operatively associated with a roller mounted carriage operatively secured to a supporting frame which allows the table and associated carriage to move outwardly from the supporting frame to allow the cutting of larger workpieces than could ordinarily be accomplished on the ordinary, conventional table saw.

  • Patent number: 6199694
    Abstract: A paint brush protection device in the form of a sheath is configured for containing the bristles and the ferrule portion of a paint brush, for keeping the bristles in proper shape and alignment. The sheath has a bristle-holding portion with an expansible bottom opening for receiving a paint brush in a handle-first orientation, and a ferrule-holding portion with an expansible top opening for allowing the handle to extend outwardly from the sheath, and for allowing the paint brush positioned within the sheath to be removed therefrom. The sheath includes front and rear sheath halves that are joined together along their sides for a portion of the length below the top opening. The part of the sheath where the sheath halves are joined together forms the ferrule-holding portion of the sheath. Between the ferrule-holding portion and the bottom opening, the sheath halves are unjoined and are resiliently separable from each other to allow the expansion of the bottom opening to receive a paint brush.

  • Patent number: 6080041
    Abstract: A saw with a compact frame that permits the cutting of large workpieces and that can be repeatedly operated repeatedly without requiring manual activation of an on/off switch. A special pivoting support arm pivots outwardly away from a motor assembly to allow the cutting of large workpieces while allowing the size of the saw to remain relatively compact and portable. An automatic power switch mechanism also is provided to automatically turn on the saw motor upon the placement of a workpiece adjacent to the saw blade. The saw table can be slid beyond the frame for the cutting of large workpieces.
