Abstract:
A pop-up wheel device for use in material handling equipment. In one embodiment, the pop-up wheel device includes a housing, which is a can of generally track-shaped transverse cross-section. A nipple is mounted in the housing bottom to permit fluid under pressure to pass to and from the interior of the housing. A cap, which includes a central opening, is positioned over and is secured to the housing. A piston is slidably mounted within the housing between a lower position and an upper position. A seal is fitted around a lower portion of the piston and creates an air-tight chamber between the piston and the housing. A spring biases the piston towards the lower position. A wheel that is freely rotatable in one direction is coupled to the piston using a wheel mount. The wheel may be removed from the wheel mount without removing the cap from the housing.

Claim (Index 15):
The pop-up wheel device as claimed in  claim 10  wherein the piston comprises a bottom wall, a lower side wall extending from the bottom wall, a shelf extending from the lower side wall, an upper side wall extending from the shelf, and an open top, wherein, when viewed from above, the upper side wall is longer and wider than the lower side wall, with the shelf extending generally horizontally between the top of the lower side wall and the bottom of the upper side wall, and wherein the bottom wall slopes upwardly and then curves slightly downwardly as one moves inwardly from a periphery of the bottom wall, thereby defining a track-shaped recess spaced inwardly from the periphery of the bottom wall.
