Abstract
An expandable shoe and last board are disclosed. For the shoe, a front outer assembly and a rear outer assembly are attached to a flexible, expandable segment. An adjustable inner assembly has a manually urgable control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe. A visualization window may be used to provide a view port to the inner assembly to see the adjustment of a shoe dimension.
Claims24
An expandable shoe, comprising:
- a front outer assembly;
- a rear outer assembly;
- an expandable segment attached to the front and rear outer assemblies to define a shoe outer shell wherein the expandable segment extends at least partially along each side of the outer shell and transversely across the bottom of the outer shell;
- and
- an adjustable inner assembly, disposed within the outer shell and attached to the front and rear outer assembly, the inner assembly having 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 and to thereby adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe.

An expandable shoe, comprising:
- a front outer assembly;
- a rear outer assembly;
- an expandable segment attached to the front and rear outer assemblies to define a shoe outer shell wherein the flexible segment extends at least partially along each side of the outer shell and transversely across the bottom of the outer shell;
- and
- an adjustable inner assembly, disposed within the outer shell and attached to the front and rear outer assembly, the inner assembly having a control to adjust a dimension of the inner assembly and thereby a corresponding dimension of the shoe wherein the inner assembly includes
- a first board portion and a second board portion, each shaped for relative movement with respect to the other;
- and
- a manual adjustment assembly having a portion thereof manually accessible from the outer shell and another portion thereof engageable with an engagement member fixed to one of the first and second board portions, wherein the engagement member is translationally movable to at least one of two states, in which a first state allows the first and second board portions to be moved relative to each other to adjust a dimension of the shoe and wherein the second state inhibits such movement.

An adjustable last board, comprising:
- a first portion and a second portion, each shaped for relative movement with respect to the other;
- and
- a manual adjustment assembly having a portion thereof shaped for manual engagement thereof and another portion thereof engageable with an engagement member that is fixed to one of the first and second portions, wherein the engagement member is translationally movable to one of at least two states, in which a first state allows the first and second portions to be moved relative to each other and wherein the second state inhibits such movement;
- wherein one of the first and second board portions includes a toothed segment and wherein the manual adjustment assembly includes a rod segment shaped for manual engagement thereof;
- a toothed member and a deformable member in a biasing relationship to position the toothed member into a lock state with the toothed segment when the deformable member is in a relaxed state and into an unlocked state when the deformable member is in a deformed state.
2 more elements
An expandable shoe, comprising:
- an outer shell;
- and
- an adjustable inner assembly, disposed within the outer shell, the inner assembly forming a last board having
- a first board portion and a second board portion, each shaped for relative movement with respect to the other;
- and
- a manual adjustment assembly having a portion thereof manually accessible from the outer shell and another portion thereof engageable with an engagement member fixed to one of the first and second board portions, wherein the engagement member is translationally urgable to at least one of two states, in which a first state allows the first and second board portions to be moved relative to each other to adjust a dimension of the shoe and wherein the second state inhibits such movement;
- wherein one of the first and second board portions includes a toothed segment and wherein the manual adjustment assembly includes
- a rod segment manually accessible from the outer shell;
- toothed member and a deformable member in a biasing relationship to position the toothed member into a lock state with the toothed segment when the deformable member is in a relaxed state and into an unlocked state when the deformable member is in a deformed state.
