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 10):
A pop-up wheel device for use in material handling equipment, the pop-up wheel device comprising:\n (a) a housing, the housing comprising a bottom wall, a side wall extending upwardly from said bottom wall, a flange extending outwardly from the top of the side wall, and an open top; (b) a cap, the cap being positioned on top of the housing and being secured to the flange of housing, the cap comprising an opening; (c) a piston, the piston being slidable within the housing between a lower position and an upper position; (d) a nipple, the nipple being mounted in the housing for use in transmitting fluid under pressure to and from said housing for use in sliding the piston between the lower position and the upper position; (e) a spring for biasing the piston towards the lower position; (f) a wheel mount, the wheel mount being seated on the piston; and (g) a wheel assembly, the wheel assembly being coupled to the wheel mount and comprising a contact wheel, the contact wheel being freely rotatable in one direction, wherein, when the piston is in the lower position, none of the contact wheel extends above the cap, and wherein, when the piston is in the upper position, a portion of the contact wheel extends above the cap.
