  • Patent number: 11046480
    Abstract: This disclosure relates to portable storage boxes, also called job boxes, that may be adapted for use on construction sites. Existing boxes are typically too large and heavy to move by just one person without additional equipment. Existing storage boxes are difficult to maneuver in tight spaces. This invention allows a job box to be broken down into three sub-assemblies of roughly equal size. The individual sub-assemblies are easier to carry since they are compact and can be held close to the body when the user is in a standing position. The individual sub-assemblies stack well against each other allowing the storage box to be stored and transported in a more space efficient way than present art unitary assembly storage boxes.

  • Patent number: 10188897
    Abstract: Handles for use in exercise apparatus and in lifting apparatus are provided. The handles have an elongated handle body with a top head, a bottom head, and a central bore extending along a longitudinal axis. A top pulley is coupled to the top head and is rotatable around a top axis that is substantially perpendicular to the longitudinal axis. A bottom pulley is coupled to the bottom head and is rotatable around a bottom axis that is substantially perpendicular to the longitudinal axis. At least one secondary pulley is associated with at least one of the top pulley and the bottom pulley. A cord is disposed on a circumferential surface of the top pulley, the cord passing through the central bore and being disposed on a circumferential surface of the bottom pulley, so that when the handle body is moved, the top and bottom pulleys rotate to allow the cord to travel smoothly through the central bore.
