  • Patent number: 10638865
    Abstract: A carpet stretching assembly includes a carpet stretcher that has a strike plate, a gripper and a tube extending therebetween. The carpet stretcher is positionable on a floor having the gripper engaging carpet on the floor and having the strike plate horizontally oriented for striking with a knee. The tube has a first portion that is slidably coupled to a second portion such that the tube has an adjustable length. A tube shock absorber is positioned within the tube and the tube shock absorber biases the strike plate away from the gripper. The tube shock absorber absorbs impact energy from the striker shock absorbers. Moreover, the tube shock absorber transfers the impact energy from the striker shock absorbers into the gripper. In this way the tube shock absorber enhances stretching the carpet when the strike plate is struck.

  • Patent number: 7320490
    Abstract: An impact handle for a shovel and other tools to assist the user or laborer in digging and/or moving material such as dirt or snow, or other compacted materials. An impact handle with a shovel attachment would have similar physical features as generic shovels on the market today. However, the impact handle includes an impact generator within the handle. As a user or operator applies his/her foot-pressure on the foot actuator located at the top of the scoop or blade, the impact generator using electro-magnetic principles produces impulses of 1 to 10 hertz of downward blows. These impulses reduce the effort required by the operator to force the tool scoop or blade to penetrate the material being excavated. The impact handle dramatically reduces time required to complete hand excavation projects. The impact handle can also be used, but is not limited to, to reduce the time required for chiseling, scraping, prying, nail pulling and carpet-stretching.

  • Patent number: 7246834
    Abstract: The cushion pad structure of the carpet installation tool comprises a rubber covering layer, a rubber foam body and an assembly board. The foam body is disposed in the covering layer. The foam body comprises a thrust face, which has a plurality of the first holes with at least a predetermined depth. The thrust face is designed so that a technician's knee or heel receives less reaction force from the impulse imparted due to the plurality of the first holes and softened hardness. Under the impulse force, the hardness of the advance gradually cushioning structure increases its hardness slowly and generates a maximum hardness at a proper position that may be experimentally determined, efficiently transferring the maximum impulse force to the carpet installation tool. The carpet installation tool therefore provides protection for the technician's knee and ankle joints, and efficiently transfers the impulse force.
