A modular roller device to facilitate horizontal displacement of objects and materials, including large, heavy, or bulky objects and materials comprising a frame constructed of at least one formed rod, a first rolling member rotatably mounted to a first support arm, and a second rolling member rotatably mounted to a second support arm, wherein the first rolling member may be arranged in a generally parallel orientation relative to the second rolling member. The frame may comprise at least one extending section, and the opposing first and second support arms may be coupled thereto. The at least one extending section may comprise a longitudinally extending section and/or a diagonally extending section. The modular roller device may further comprise at least one secondary extending section. The modularly roller devices can be further combined to a form a system to facilitate the horizontal displacement of objects and materials.

A transportation assembly structured and configured to facilitate the storage, transportation, and use (e.g., viewing) of a television or other display device is presented herein. The transportation assembly includes a positioning assembly structured to movably mount or support the display device to a main body. In particular, the positioning assembly includes a linear actuator as well as guide rails to selectively position the display device between a raised position and a lowered position. A plurality of collapsible legs are provided to allow the assembly to be either transported on wheels while the legs are extended or placed into a vehicle while the legs are collapsed.

A navigation system uses a dead reckoning method to estimate an object's present position relative to one or more prior positions. In some embodiments, the dead reckoning method determines a change in position from the object's heading and speed during an elapsed time interval. In embodiments suitable for use with wheeled objects, the dead reckoning method determines the change in position by measuring the heading and the amount of wheel rotation. Some or all of the components of the navigation system may be disposed within a wheel, such as a wheel of a shopping cart.

A telescoping cart apparatus and method consists of a carrier configured to include receptacles for carrying cleaning materials. A carry handle is connected with the carrier where the carry handle is connected across the middle of the carrier. A divider is connected beneath the carry handle and is connected with the carrier such that the divider creates two separate sections of the carrier. Telescoping support legs are connected with the carrier where the telescoping support legs are adjustable from a retracted position within the carrier to an extended position outside of the carrier. An extendable adjustment handle is connected with the carrier. A button in the carry handle where the button is connected with the telescoping support legs for adjusting the positions of the telescoping support legs and wheels connected with the telescoping support legs.

Herein is disclosed a dolly for carrying a heavy object by means of a car with a trailer hitch. The dolly includes a rigid frame adapted to securely hold an object on a front face of the rigid frame. Left and right parallel pneumatic wheels are positioned on a left and right sides the rigid frame, respectively and extending perpendicularly away from the rigid frame opposite a platform. Each of the pneumatic wheels is highway rated. Each of the pneumatic wheels has a hub rotatably mounted to the rigid frame by a flange member projecting perpendicularly from the rigid frame, the flange members positioning the hubs away from the rigid frame such that the hubs are at least several inches from a back face of the rigid frame. The dolly also includes a retractable boom having a trailer hitch coupling on a distal end. The retractable boom is selectively movable between a retracted and extended position. Finally, the dolly includes a lock for releasably locking the retractable boom in its extended position.

A Wheeled Cart which can be connected in the same manner as the car's own wheel, allowing, upon removal of the car wheel, the positioning of the Wheeled Cart with the same screws or the same nuts, without needing to make any adaptations; the idea was to develop a device that adapts to the different configurations of wheel fastening on wheel holders, according to how it is designed on the wheel holder, which is why a very important point that is taken into account is that the chassis or main body must regulate the layout or configuration of the holes, as well as the diameter of the wheel to be replaced, the objective is to enable movement of the car when the latter cannot do so with its wheels, which is why the device is designed based on two bodies named chassis facing each other, with a common central connection part, one superior part named superior end and one inferior part named inferior end, which accommodates a 360 directional wheel and a third connecting element between the chassis, which affixes the position of the latter with the purpose of securing it; and the device is characterized by the fact that its Body which we name Chassis is comprised of two parts connected in the central area of each of the parts by means of a bolt bushing, and which we will hereinafter name Central Part, and from this Central Part a formation extends to each part of the chassis, in a symmetrical manner, generating what we shall name Superior Ends and the other Inferior Ends; each of the latter accommodates a wheel with its corresponding fork and 360 pivotal axis; and in turn each Superior End has on its extremities through-holes of a greater dimension than that of the adjustment screws for the wheels of the car and of a lesser dimension than the diameter of the nut of that screw or screw head; in turn, between each of the Superior Ends and the Central Part of each part of the body of the chassis there is a screw with a wing nut fixed to the upper body of the chassis, with a component named bridge located between both screws and affixed by the wing nuts, with a through-hole in its central part of the same diameter as the through-holes at the extremities of each of the Superior Ends and this bridge has an oval orifice instead of a circular orifice in the connection with each screw by means of a wing nut.

An apparatus for interconnecting a hand truck or dolly to a vehicle receiver or hitch while hauling a heavy load. The apparatus includes a base, an extendable lever arm and a separable intermediary glide. The base couples with the hand truck, the lever arm is extendable from the base, and the intermediary glide interconnects the lever arm to a receiver attached to a vehicle.
