Claim 14:
15. A telescopically extendable truck bed shell, consisting of:
a truck including a truck bed, said truck bed having side rails;
a shield assembly including shields telescopically connected which are slidably mounted to said truck bed by means of bearings, said shields having a proximal shield which is fixed with respect to the rest of the shields, said shields having a distal shield which includes a door, the shields have an extended configuration and a contracted configuration, each of the shields have two lateral sides and a top side;
a transmission assembly including a motor, threaded rods, said bearings, and housings, wherein said motor is electrically powered and remotely controlled, the housings are elongated members that enclose the threaded rods, each of the housings has a slot that leaves a portion of the threaded rod exposed, the bearings receive the housings and interact with the threaded rods through said slot of each housing by means of racks, the bearings are linear bearings that moves along said housing when said threaded rod rotates, the motor transmits motion to the threaded rods by means of shafts and transmission gears, wherein said threaded rods are mounted on said truck bed above said side rails, wherein a bottom portion of said bearings is slidable mounted to said side rails, wherein a central portion of said bearings are slidable attached to said threaded rods, wherein a top portion of each of said bearings is fixed to a corresponding shield of said shields, wherein said motor is actuated to force the threaded rod to slide the bearings along its length to retract or extend the shields; and
an actuation assembly including a remote controller a receiver and a driver, the remote controller includes buttons, a transmitter and a battery, each of the buttons have a predetermined function that is wirelessly transmitted by said transmitter, the battery provides electrical energy to said transmitter, the remote controller is configured to permit a user to remotely extend or contract said shields, the receiver may receive a signal that comes from the transmitter, wherein said signal carries predetermined instructions, the receiver is electrically connected to the driver, the driver is electrically connected to the motor, the driver changes a direction in which the motion is delivered by the motor, said direction is dictated by the remote controller.
