  • Publication number: 20120025480
    Abstract: Size-adjustable footwear includes a body in which first and second insoles are received, the insoles being nested together and one upon another with both extending to generally cover the length and width of the sole of the footwear body. A first insole has a re-entrant section for partially enclosing at least part of the periphery of the forefoot of a wearer and includes a first toe cap, and lateral and medial flanges integral with the first toe cap. The second upper insole includes a reentrantly shaped second toe cap and a heel cup in which a first longitudinal dimension, between the heel cup and the second toe cap, defines a first size, and a second longitudinal dimension, between the body heel and the first toe cap, defines a second size larger than the first size. A user may select footwear based on the smaller first size, and then remove the first and then the second insole to accommodate growth of the feet.

  • Publication number: 20020180169
    Abstract: A handle of a kick board is hingably connected to a chassis of a front truck of the kick board. The hinge connection consists of a lower connector fixed to the chassis and an upper connector fixed to a lower end of the handle. The connectors have co-operating vertical surfaces that constrain folding movement of the handle through a vertical plane and are held pivotably together by a sleeve pin. The hinge connection is locked by engaging a spring biassed plunger into a suitably formed vertical slot in the lower connector. The lock is released by raising the plunger by sliding a manually grippable sheath upwards along the handle so as to move a pin, that passes through the plunger, upwards.
