Furthermore, the connection comprises a means (12) for locking/unlocking the handlebar relative to frame (2) and/or to a driven wheel (3) from a locking position where handlebar (20) is attached to frame (2) and/or to driven wheel (3), this locked position of handlebar (20) enabling electric propulsion system (1) to be moved by means of handlebar (20), to an unlocking position enabling at least free motion of handlebar (20) relative to frame (2) and/or driven wheel (3).

A linkage for interconnecting material handling equipment of a convoy is provided. The linkage comprises a rod having first and second opposite ends, a first pivot joint between the first end and the second end, the first pivot joint having a first pivot axis extending transversely to a longitudinal axis of the rod. A biasing member is secured to the rod and deformable upon rotation of the first pivot joint about the first pivot axis. The biasing member resists at least partially to the rotation of the first pivot joint about the first pivot axis. A first coupling and a second coupling are respectively pivotally mounted to the first end and the second end of the rod for rotation about respective pivot axes transverse to both the longitudinal axis of the rod and the first pivot axis.

Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

The invention relates to a removable electric propulsion system (1) for a rolling object, propulsion system (1) comprising a frame (2) provided with at least one wheel (3) driven by an electric machine (10), and at least one non-driven wheel (4), and means (5) for coupling propulsion system (1) to the rolling object. In addition, coupling means (5) comprise means for gripping and lifting at least one wheel of the rolling object. Besides, propulsion system (1) comprises a seating device with a seat (51) and a backrest (50), and this seating device is foldable between a deployed position allowing a user to sit and a folded position.

The invention also relates to a method for deploying/folding the seating device of electric propulsion system (1).

In some implementations, a utility cart includes (a) a cargo hold having a cargo bed; (b) an assembly having a wheel arm having a first catch, a handle arm having a second catch, and a wheel; the wheel arm and handle arm coupled together at an angle and adjacent a pivot point; the wheel rotatably coupled to a distal end of the wheel arm; (c) a locking mechanism and a spring member, the locking mechanism having a first locking pin and a second locking pin; and (d) a plurality of bearing wheels disposed below a bottom surface of the cargo bed.

A convertible, all-terrain gear cart convertible between modes of manual propulsion, trailering, and support by a motor vehicle. A control arm with a trailer hitch connector permits trailering or manual propulsion and is pivotally coupled to a first end of a cargo bin, and a vehicle engaging member to permit support and transport by a motor vehicle projects from the second end of the cargo bin. Detachable, all-terrain wheels with lateral axes of rotation are retained at a mid-portion of the cargo bin. Cargo retention and roll bars are removably coupled to the cargo bin, and a retractable support leg can cooperate with the wheels to stabilize the gear cart. The vehicle engaging member can comprise a receiver with a mitered end forming a shelf that can be rested on a rigid tongue of a trailer hitch adapter to permit levering of the gear cart relative to a vehicle.

A motorized scooter cart system is a system that enables a user to comfortably move around while transporting objects or people. The system may include a scooter deck, at least one scooter wheel, a linkage arm, at least one seat assembly, a handlebar assembly, and a pushcart. The scooter deck is designed to support the weight of the user so that the user can freely maneuver the pushcart. The at least one scooter wheel provides the translational force necessary to move the present invention. The linkage arm enables the coupling of the scooter deck to the pushcart. The linkage arm also facilitates the maneuvering of the pushcart. The at least one seat assembly enables the user to comfortably seat while maneuvering the pushcart.
