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 19):
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, the piston comprising a bottom wall, a lower side wall extending upwardly from the bottom wall, a shelf extending outwardly from a top of the lower side wall, and an upper side wall extending upwardly from an outer periphery of the shelf; (d) a seal, the seal being fitted around the lower side wall of the piston and engaging the side wall of the housing to create an air-tight chamber between the piston and the housing; (e) 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; (f) a spring for biasing the piston towards the lower position; (g) a wheel mount, the wheel mount comprising a first member and a second member, the first member being seated on the bottom wall of the piston and comprising a bottom, a side, a top, and a cavity extending downwardly from the top, the second member being inserted over a portion of the first member and comprising a top wall, a side wall extending downwardly from the top wall, a peripheral flange extending outwardly from a bottom of the side wall, and an open bottom, the peripheral flange of the second member being seated on the shelf of the piston; and (h) a wheel assembly, the wheel assembly comprising an axle and a contact wheel, the axle being disposed within the cavity of the first member of the wheel mount, the contact wheel being freely rotatable in one direction on the axle, a portion of the contact wheel extending above the wheel mount, 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.
