An expandable car jack includes a vehicle lifting assembly with an upper lifting member, a lower lifting member mechanically coupled to the upper lifting member, and a lifting mechanism capable of moving the upper lifting member to a plurality of raised height positions. A base is coupled to the vehicle lifting assembly and includes a first base support member, a second base support member, and a base support coupler that is operable to selectively couple the first base support member to the second base support member in at least a first coupling position and a second coupling position. The base support coupler selectively mechanically maintains a parallel alignment and a perpendicular alignment of the first base support member and the second base support member when the base support coupler is in the first coupling position, allows the first base support member and the second base support member to freely move between the parallel alignment and the perpendicular alignment when the base support coupler is in the second coupling position, and remains mechanically coupled to at least the first base support member in the first and second coupling positions so that the first base support member cannot move with respect to the second base support member without a mechanical alteration to the base support coupler prior to moving either the first base support member or the second base support member.

A transport assist equipment assists transport of an object. The transport assist equipment includes a plurality of mecanum wheels, a plurality of motors, a first sensor, and a controller. The plurality of mecanum wheels are attached to the object. The plurality of motors are respectively attached to the plurality of mecanum wheels, and configured to respectively drive the plurality of mecanum wheels. The first sensor detects a force applied to the object. The controller is electrically connected to the first sensor and controls the plurality of motors. The controller drives the plurality of mecanum wheels via the motors so as to propel the object along a direction in which the object receives the force, based on a detection signal of the first sensor.

A wheeled device for increasing the mobility of a snowmobile or ski-bound vehicle, wherein the wheeled device, having a cylindrical axle, is attached to the bolt on the interior of a sled ski underneath the snowmobile sled, which raises the skis off the ground and does not increase the snowmobile sled width. The wheeled device surrounds the interior sled ski bolts and nuts thereon and is tightened onto said bolts and nuts by way of a tightening wheel. The snowmobile is thus able to drive on the wheeled devices so that it can conveniently move from one location to another without damaging the bottom of the skis if on rough or unstable terrain.

This invention is directed to a kit of coolers that offers a number of improvements over the prior art. The coolers are modified to specifically accommodate frozen gel ice packs instead of ice cubes. Because there is no spill water, the coolers open with front-facing pull-out drawers. The coolers stack atop one another with interlocking parts. Easy transport is provided by a handle and wheels, which are attached to the bottom (main) bin. Internally, the cooler bins are compartmentalized horizontally or vertically with dividers. Hollow spaces within the walls and dividers of the bins accommodate frozen gel ice packs. Overall, the coolers are easier to pack and unpack, stack, load into a car, and transport on the ground than conventional ice chest coolers.

Material transport equipment includes first and second pairs of main wheels and first and second pairs of extension wheels rotatably attached to a frame. The main wheels have a diameter greater than the extension wheels and are spaced further apart than the extension wheels. The main wheels and the extension wheels are adapted to roll on the rails of a main section and of an extension, respectively, of an extension ladder. The equipment may be used as a hand truck for carrying a payload on ground wheels rolling on the ground. The apparatus may then be leaned to position main wheels of the apparatus onto rails of a main section of an extension ladder. Extension wheels on the apparatus move onto rails of the extension of the ladder as the apparatus moves up from the main section onto the extension using a rope or cable.

The present invention relates to a novel trolley coupling structure that allows coupling of base parts of trolleys aligned in the vertical or horizontal direction. The present invention provides a trolley coupling structure in which a first receiving recess part is provided in a base part of one trolley, a second receiving recess part is provided in a base part of another trolley, a locking member is pivotally attached to the first receiving recess part, a recess part body and a bent section are formed in the respective first and second receiving recess parts, and retaining of the locking member is achieved by constraining and locking a constraining piece part of the locking member at the bent section.

Robotic vehicle and use thereof for displacing a holder for goods, which is for instance loaded with goods, which vehicle can be operated in an empty position and a loaded position, comprising of (1) moving the robotic vehicle to a position under the holder in a first direction, wherein the robotic vehicle is in the empty position, wherein a holding means is countersunk in a body of the vehicle; (2) lifting the holder, wherein the robotic vehicle lifts the holder by performing a vertical movement of the holding means relative to the wheels of the vehicle, such that the holding means comes into contact with an underside of the holder, wherein the robotic vehicle transfers to the loaded position; (3) rotating driven wheels of the robotic vehicle from the first direction to the second direction without the body of the vehicle being rotated, and (4) displacing the robotic vehicle in the loaded position in a second direction, wherein the first and second direction enclose a mutual angle of between 60 and 120 degrees, preferably 75 and 105 degrees, more preferably 85 and 95 degrees, such as a substantially right angle.

A dolly for a water vessel is an apparatus that facilitates the transportation of a water vessel on land. The apparatus serves as a universal attachment for water vessels. The apparatus includes left brace assembly, a right brace assembly, a connector bar, a first roller assembly, and a second roller assembly. The left brace assembly and the right brace assembly attach onto a transom of a water vessel. The left brace assembly and the right brace assembly may be adjusted to accommodate transoms of varying heights. The connector bar mounts the left brace assembly with the right brace assembly, thereby positioning the first roller assembly and the second roller assembly. The first roller assembly and the second roller assembly uplift the water vessel and rolls the water vessel across the ground. The apparatus further includes a cradle mechanism which further supports a paddleboard or a kayak.

An improved movable decorative base assembly is provided that includes a receptacle having a bottom, at least one upstanding side wall forming a hollow interior and an open top. The base assembly includes a wheeled, base carriage on which the receptacle may be placed. The decorative base assembly further includes a pole receiver, which is carried by the base carriage and has a receiving hole for attaching a tube or other elongated body carrying a parasol canopy. The receiving hole of the pole receiver aligns with a through hole in the bottom of the receptacle, allowing the elongated body to extend through the receptacle and attach to the pole receiver, the assembly forming a unitary body which can be rolled on a floor or surface. The decorative base assembly allows safe, comfortable, and stable maneuvering, while alleviating physical strains otherwise felt by those utilizing alternative assemblies.

A mobility device for moving an object across a surface having a non-planar obstruction to allow movement of the object over the obstruction. The mobility device has a walking wheel assembly and an attachment mechanism. The walking wheel assembly has at least two wheels and an offset camshaft. The offset camshaft has a lobe associated with each wheel. The lobes are in a non-linear relationship such that one wheel is a leading wheel and one wheel is a trailing wheel. The offset camshaft allows the leading and trailing wheels to pivot upward and downward independent of each other. The attachment mechanism attaches the walking wheel assembly to the object. The mobility device can include a deflector assembly having a pair of deflector arms that are pivotally connected to a cam-axle which is attached to the offset camshaft to help guide the mobility device over non-planar areas.
