Abstract:
1. A stand for a machine, comprising: a mounting support for supporting the machine thereon, and having a plurality of legs; at least one wheel unit having a pivotal shaft and a wheel holder pivotally connected to one of the legs of the mounting support by the pivotal shaft and a wheel rotatably connected to the wheel holder, wherein the connection location of the wheel and the location of the pivotal shaft of the wheel holder are spaced apart; an actuating member pivotally connected at a first pivotal location thereof to the mounting support; at least one link having a first end pivotally connected to the wheel holder of the wheel unit, wherein the connection location of the first end of the link and the location of the pivotal shaft of the wheel holder are spaced apart, and a second end pivotally connected to the actuating member, wherein the connection location of the second end of the link and the first pivotal location of the actuating member are spaced apart, such that when the actuating member is pivoted, the wheel holder is pivoted by the link in order to move the wheel downward for engaging a supporting surface, thereby lifting the leg off of the supporting surface; and a locking mechanism having a first rod member with a first end pivotally connected to the mounting support, and a second rod member with first and second opposite ends respectively pivotally connected to a second end of the first rod member and pivotally connected with the actuating member such that when the first rod member is pivoted relative to the mounting support, the actuating member is forced to pivot relative to the mounting support by the second rod member.
