And Occupant Propelled Seesaw Patents (Class 472/4)
  • Patent number: 9468804
    Abstract: The present invention is a gimbled push-up bar assembly mounted upon a rotatable hinge, thereby providing instability in three dimensions for which a user will have to compensate in use. The bar may be locked into two dimensions by the use of a lock pin, or may freely move in all three dimensions. Handgrips are provided which are bent downwards to provide guards for a user's hands when in the free-motion configuration. The bar itself is removable from the hinge and stand assembly and may be used as a stable push-up bar assembly, resting on the guards.

  • Patent number: 8206275
    Abstract: A balance training device includes at least one supporting base and at least one plank member. The supporting base includes a plank connecting portion formed with a plank coupling groove that opens upwardly. The plank coupling groove includes a first groove section and a second groove section that intersects the first groove section. The plank member includes a plate portion and a rib structure disposed on a bottom face of the plate portion. The rib structure removably engages the plank coupling groove of the supporting base. The rib structure includes a first rib part to engage the first groove section and a second rib part to engage the second groove section.

  • Publication number: 20080234058
    Abstract: Play equipment that combines the movements of a teeter totter and a merry-go-round includes a support for suspending a riding assembly, a riding assembly upon which a rider is supported, such as upon which a rider sits or a rider hangs from, and a suspending means which suspends the riding assembly from the support for both rotational movement with respect to the support and up and down movement with respect to the support. The up and down movement may be achieved by pivotal movement or by swinging movement. The support of the invention may be adjustable to adjust the height of the riding assembly. When seats for the riders are provided, the seats may include restraining means, such as back and side rails to help keep the rider in the seat. The equipment can include a single beam providing a pair of oppositely extending arms as with a traditional teeter tooter, or can include additional beams or arms, such as four arms, to accommodate additional riders.

  • Patent number: 6811826
    Abstract: The coated multilayer structure comprising a polymeric base layer, a zero valent material barrier layer, and a top coat on the zero valent material barrier layer, the top coat comprising a soluble compound capable of reducing the permeability of the multilayer structure to gas or vapor. The zero valent material barrier layer can also enhance barrier to UV light. A method for enhancing the gas or vapor barrier properties or the UV light barrier properties of a multilayer polymeric/inorganic structure is also disclosed. According to one embodiment, Si coated polyethylene terephthalate containers are coated with a gas or vapor barrier enhancing top coat. A method for recycling containers coated with a zero valent material barrier layer is also disclosed.
