A carrying device is provided that includes a load compartment configured to accommodate a load; at least one wheel rotatably coupled to the load compartment and configured to roll along a ground; a shaft attached to the load compartment; and a coupling element attached the shaft. The coupling element is configured to couple the carrying device to a person in a manner that allows towing of the carrying device by the person. Additional versions of the carrying device and a system including the same are also disclosed.

A wheel pack assembly includes a pack portion wearable by a user and a wheeled portion removably coupled to the pack portion. The pack portion includes a support frame coupled to a rear surface thereof. The support frame includes articulating arms and stabilizing elements. The wheel portion includes a frame and a first wheel set coupled to the frame and disposed at a location spaced apart from a rear end of the wheeled portion. The frame includes a first portion and a second portion that are joined together at a bend and such that the second portion defines a transport bed of the assembly.

A cart is disclosed which is capable of being wheeled to a vehicle and mounted thereon through a mount secure coupling attached to the cart and a secure receiver attached to the vehicle. Upon secure attachment to the vehicle, the carts undercarriage assembly including wheels are capable of being retracted into the top deck assembly of the cart. Therefore, the vehicle maintains clearance from the road even after the cart is attached. Upon reaching a destination, the undercarriage of the cart is lowered and the cart is detached from the vehicle. The cart is then able to be wheeled away. The cart allows for transportation of loads without the need for the operator to actually carry either the load or the cart at any stage from start to finish or perform any additional steps to safe and securely attach the cart to the vehicle.

A wheel pack assembly includes a pack portion wearable by a user, a wheeled portion removably coupled to the pack portion, and a power assist system. The pack portion includes a first interfit element. The wheeled portion includes a frame, a second interfit element coupled to frame and configured to removably couple with the first interfit element of the pack portion, and a first wheel set coupled to the frame and disposed at a location spaced apart from a rear end of the wheeled portion. The power assist system includes a motor mechanically coupled to the first wheel set, at least one sensor coupled to the at least one of the first interfit element and the second interfit element, and a controller configured to operate the motor based on feedback from the at least one sensor.

A handle configured to be mounted on a pole (e.g., of an IV stand). The handle includes a handle grip having first and second ends with a central section therebetween. The central section is lower than the first and second ends. The handle grip is configured to be gripped by a user at a location between the central section and one of the first and second ends. The handle grip may include first and second sections that each extend upwardly from a central section. The first section is configured to be gripped at a natural grip angle by the user's a right hand and the second section is configured to be gripped at the natural grip angle by the user's a left hand. The handle may include a connector portion configured to be mounted to the pole and connected to the handle grip.

A pull-behind carriage has an auxiliary wheel mounted on a reconfigurable drawbar. When the pull-behind carriage is converted to a push carriage, the drawbar is folded so that the auxiliary wheel is positioned on the ground to act as an extra, supporting wheel. Joints in the drawbar are palm operated and can be rotated without continuing to hold the joint. The drawbar may also serve to move the axle of the main wheels backwards when the carriage is converted from the pull-behind mode to the push mode.

An apparatus and method for towing a load behind a person is disclosed which reduces or dampens the effect of human movement on the load and vice versa. Further, the apparatus and method reduce or dampen the impact and vibrations resulting from traveling over a surface. In one embodiment, the apparatus and method is comprised of a harness for a person to wear, a carriage, and a bow connecting the harness and the carriage.

An article of manufacture for a universal push bar to create a hygienically safe shopping cart according to the present invention is disclosed. The universal push bar is made of a main push bar having a first end and a second end, a pair of support members having an upper end coupled to the main push, a first support member coupled about the first end of the main push bar and a second support member coupled about the second end of the main push bar, and a pair of claiming mechanisms coupled to each lower end of the pair of support members, the pair of claiming mechanisms having a pair of opposing claiming surfaces configured to attach the clamping mechanisms to a shopping cart handle.

A handle assembly for exerting forces on a vehicle is disclosed. The handle assembly includes a handle, a handle housing, an optional vehicle mounting plate, and a single latching mechanism. The handle has a first support post and a second support post. The first support post has a first end, the second support post has a second end, and the first end is operably coupled with the second end. The handle housing has a first sleeve and a second sleeve. The first sleeve receives the first support post and the second sleeve receives the second support post. The vehicle mounting plate can be attached to the first sleeve and the second sleeve, and mounts the handle onto the vehicle. The single latching mechanism is operably coupled with the handle housing and is capable of releasably engaging at least the first sleeve and the second sleeve.

A harness for pulling a carriage by a person is attached to a pulling assembly, which includes a rigid drawbar coupled to the carriage and a cantilevered member coupled to the forward end of the drawbar and to the harness. The cantilevered member partially isolates cyclical motion of the person from the drawbar, and may be a spring, a sprung rigid member or a rigid member controlled by an electronic servo.
