  • In-line roller skate frame
    Patent number: 6142490
    Abstract: Improved support and adjustment of the frame on the boot are obtained by providing mounting brackets that extend transversely outwardly and beyond the underlying side walls between which the roller wheels are mounted and that contain transverse mounting slots whose transverse extents are at least as great as the spacing distance between the underlying side walls. Improved parallelism of the axles is obtained by providing diametrically opposed lobes in a mounting hole in one of the side walls at each wheel mount and by providing the corresponding axle head with a complementary shape fitting to that portion of the mounting hole containing the lobes. A tool for installing and removing the wheels from the frame is also disclosed.

  • Portable awning
    Patent number: 4805655
    Abstract: Portable awning apparatus for temporary attachment to uprights such as tree trunks or the like. The awning apparatus includes a triangular frame having a pair of side members which enclose a tree trunk, and an end member spaced outwardly from the tree trunk. A support member interconnects the two side members at a selectively adjustable distance from the apex of the triangular frame, thereby accommodating tree trunks of different sizes and permitting adjustable tilt of the awning on the tree trunk. A flexible cover extends backwardly from the end member and secures to the tree. The entire awning folds to a relatively compact and easily carryable package when not in use.
