Abstract
A foldable device includes a pivot seat, at least one leg rod unit including a leg rod that extends through the pivot seat, and a limiting member that is mounted to the leg rod, at least one connecting member pivoted to the leg rod and having a connecting segment, and a pivot unit including at least one biasing member. When the at least one connecting member is substantially collinear with the leg rod, the at least one connecting member is, under exertion of an external force, movable relative to the leg rod to a limiting position. When the external force is released, the at least one connecting member is biased by a resilient force of the at least one biasing member to move relative to the leg rod from the limiting position to a releasing position.
Claims6
A foldable device comprising:
- a pivot seat;
- at least one leg rod unit including
- a leg rod that extends through said pivot seat, and that has an upper segment above said pivot seat, and
- a limiting member that has a securing portion mounted to said upper segment, and a limiting portion extending upwardly from said securing portion and cooperating with said upper segment to define a receiving space therebetween;
- at least one connecting member having a connecting segment that is pivotally connected to said upper segment of said leg rod of said at least one leg rod unit, and an end segment that is opposite to said connecting segment;
- and
- a pivot unit including at least one biasing member that is connected between said upper segment of said leg rod of said at least one leg rod unit and said connecting segment of said at least one connecting member for resiliently biasing said connecting segment away from said upper segment;
- wherein, when said at least one connecting member is pivoted relative to said leg rod of said at least one leg rod unit until said at least one connecting member is substantially collinear with said leg rod and said end segment of said at least one connecting member is away from said leg rod, said at least one connecting member is, under exertion of an external force, movable relative to said leg rod to a limiting position, where said connecting segment of said at least one connecting member engages a bottom end of said receiving space of said at least one leg rod unit such that pivot movement of said at least one connecting member toward said leg rod is blocked by said limiting member of said at least one leg rod unit;
- and
- wherein, when the external force is released, said at least one connecting member is biased by a resilient force of said at least one biasing member to move relative to said leg rod from the limiting position to a releasing position, where said connecting segment is disengaged from said bottom end of said receiving space such that the pivot movement of said at least one connecting member toward said leg rod is permitted.
