  • Patent number: 6883254
    Abstract: An improved expandable shoe and inner assembly are disclosed. The expandable shoe includes an outer shell and an adjustable inner assembly is disposed within the outer shell. The inner assembly has a first board portion and a second board portion in overlapping engagement with each other and a control to adjust the position of the first board portion relative to the second board portion. The control includes a locking mechanism shaped to engage and hold one of the first and second board portions, a biasing mechanism to bias the locking mechanism into engagement with one of the first and second board portions; and an urging member having a proximal portion external of the shoe outer shell and positioned and movable transversely to a longitudinal direction of the shoe and in transverse alignment with the locking mechanism.

  • Publication number: 20050060913
    Abstract: An expandable shoe includes an outer shell and an adjustable inner assembly disposed within the outer shell. The inner assembly has a control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe. The inner assembly includes a first sole portion, a second sole portion, and a manually urgable member. The manually urgable member has at least a portion of the member accessible from the outer shell, and in engageable and releasable communication with an engagement member, fixed to one of the first and second sole portions. When the urgable member is released from the fixed engagement member the first and second sole portions may be moved to adjust the dimension of the shoe and when the urgable member is in engagement with the fixed engagement member the first and second portions resist slidable movement relative to one another.

  • Patent number: 6817116
    Abstract: An expandable shoe includes an outer shell and an adjustable inner assembly disposed within the outer shell. The inner assembly has a control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe. A visualization window provides a view port to the inner assembly so that size markings on the inner assembly may be visible through the view port. The inner assembly includes first and second board portions, each shaped for relative movement with respect to the other, and a manually urgable member. When the urgable member is released from an engagement member fixed to one of the first and second board portions, the first and second board portions may be moved to adjust the shoe dimension and when the urgable member is in engagement with the fixed engagement member the first and second board portions resist movement relative to one another.

  • Publication number: 20020178617
    Abstract: An expandable shoe includes a front outer assembly and a rear outer assembly. A flexible, expandable segment is attached to the front and rear outer assemblies to define a shoe outer shell. The flexible segment extends at least partially along each side of the outer shell and transversely across the bottom of the outer shell. Within the outer shell an adjustable inner assembly is disposed and attached to the front and rear outer assembly. The inner assembly has a control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe. In one embodiment, a visualization window provides a view port to the inner assembly. The inner assembly may include size markings visible through the view port so that a size of the adjusted shoe may be determined as shoe size is adjusted. Under another embodiment, the inner assembly includes a first sole portion, a second sole portion, and a screw drive.
