  • Publication number: 20120231935
    Abstract: A pegboard substrate is provided having holes on a surface thereof. The holes of the pegboard are configured to receive a plurality of components that interchangeably fit into the pegboard substrate to form a stretching station. The plurality of components may include pegs directly received in the holes and a seat, a handle, or a platform connected to at least one peg. The pegboard substrate together with the plurality of components received by the holes forms a modular stretching station for an individual to stretch any number of body parts to warm-up muscles prior to engaging in a physical activity. The pegboard substrate may be large enough to accommodate several stretching stations thereby forming a circuit such that a group of individuals can use the apparatus to stretch simultaneously. Add-on items may be provided including: vending machines, informational or marketing displays, trash cans, hand wipe dispensers, and the like.

  • Patent number: 4909298
    Abstract: A safety device including first and second members is attached to the pull cords for window coverings to prevent children from strangling when the children play with the pull cords. Detents on first surfaces of the first and second members couple the first and second members in detachable relationship at the first surfaces upon the exertion of forces against the members in directions transverse to such first surfaces. The first member is retained by one of the cords at a position laterally displaced in a first direction from the first surfaces and the second member is retained by the other cord at a position laterally displaced from the first surfaces in a second direction opposite to the first direction. Such retentions are provided at second surfaces transverse to, and displaced from, the first surfaces. The second surfaces are shaped relative to each other to provide for the detachment of the first and second members at the first surfaces upon the exertion of forces in the direction of the first surfaces.
