Abstract
A foldable tool stand includes a base frame, a platform pivotally and slidingly connected to the base frame at a first side, a leg support having a top end pivotally connected to the base frame, a pair of links pivotally coupled between a second side of the platform and the base frame, a driving member pivotally connected to the links, and a follower set pivotally connected to the base frame. The driving member and follower set interact to selectively lock the foldable tool stand in either an extended supporting position, where the second side of the platform is spaced from the base frame, or a collapsed position, where the second side of the platform lies adjacent to the base frame.
Claims20
A foldable tool stand, comprising:
- a base frame having a pair of first and second pivot holders positioned thereon;
- a platform having first and second opposed sides, the first side of the platform slidingly and pivotally connected to the base frame;
- a pair of links respectively pivotally coupled between the second side of the platform and the second pivot holders of the base frame;
- a leg support having a top side thereof pivotally connected to the first pivot holders of the base frame;
- a driving device pivotally coupled with the links to the second pivot holders of the base frame;
- at least one follower set having a pivot shaft inserted through a second pivot holder of the base frame, and a follower member pivotally connected to the pivot shaft;
- the follower member having a first locating portion, and the driving device having a second locating portion;
- and
- wherein the driving device is movable relative to the base frame between
- a) an extended position, where the second locating portion of the driving device is engaged with the first locating portion of the follower member so that the second side of the platform is maintained in an extended position spaced from the base frame, and
- b) a collapsed position, where the second locating portion of the driving device is disengaged from the first locating portion of the follower member so that the links are pivotable so that the first side of the platform slides along the base frame and the second side of the platform is moved to a collapsed position adjacent to the base frame.
A foldable tool stand, comprising:
- a base frame having a pair of first and second pivot holders positioned thereon;
- a platform having first and second opposed sides, the first side of the platform slidingly and pivotally connected to the base frame;
- a pair of links respectively pivotally coupled between the second side of the platform and the second pivot holders of the base frame;
- a leg support having two legs respectively having top sides pivotally connected to the respective first pivot holders of the base frame
- a driving device having two side bars respectively pivotally coupled at top ends thereof with the respective links to the second pivot holders of the base frame;
- a pair of follower sets each having a pivot shaft inserted through the respective second pivot holders of the base frame, and a follower member pivotally connected to the pivot shaft;
- the follower members each having a first locating portion, and the driving device having two second locating portions;
- and
- wherein the driving device is movable relative to the base frame between
- a) an extended position, where the second locating portions of the driving device are engaged with the first locating portions of the follower members so that the second side of the platform is maintained in an extended position spaced from the base frame, and
- b) a collapsed position, where the second locating portions of the driving device are disengaged from the first locating portions of the follower members so that the links are pivotable so that the first side of the platform slides along the base frame and the second side of the platform is moved to a collapsed position adjacent to the base frame.
