A stroller apparatus includes a front and a rear leg, a side handrail respectively connected pivotally with the front and rear legs, a handle pivotally connected with the side handrail, a seat support frame including a side bar located below the side handrail and pivotally connected with the front leg and the handle, a first seat detachably installable on the side handrail facing rearward at a first position adjacent to the handle, and a second seat detachably installable on the side bar facing rearward at a second position, the second position being located below the first position and adjacent to the handle.

The present invention relates to a releasably attached standing or level platform device for attachment to a wheeled shopping cart. The device has a generally level surface or trolley extension that releasably hooks onto a bottom of a shopping cart using a pair of hooks. The hooks are positioned at terminal ends of a rectangular U-shape arm that is attached to a telescoping arm. The U-shape arm is configured to be adjustable in width and the telescoping arm adjusts the height of the standing or level platform device. In use, a child stands on a top surface, and the wheels of the device track the movements of the wheels of the shopping cart thereby enabling the child to ride along with the wheeled cart without walking or without sitting in the wheeled shopping cart.

The disclosure provides a noise reduction structure comprising a stroller frame, a supporting frame connected to the stroller frame, and a wheel mounted on the supporting frame, the supporting frame receive a force so that the wheel contacts a supporting surface to slide; and an elastic resetting member is arranged between the supporting frame and the stroller frame, the resetting member always has a tendency to bring the supporting frame to reset. The noise reduction structure of the disclosure has a simple structure and is suitable for baby strollers or hand carts. By additionally arranging a resetting member between the supporting frame and the stroller frame, the supporting frame always has a resetting tendency, that is, when the supporting frame is unloaded, the resetting member may suspend the wheel, so as to avoid noise caused by friction between the wheel and the supporting surface.

An infant stroller apparatus includes a stroller frame having a leg frame, a stand platform pivotally connected with the leg frame about a pivot axis, and a spring connected with the leg frame. The stand platform is connected with a caster assembly disposed rearward relative to the pivot axis. The spring is configured to bias the stand platform in a direction for displacing the caster assembly downward. In some embodiment, the infant stroller apparatus can include a brake assembly operable to lift the caster assembly of the stand platform in a braking state.

A standing platform for an industrial truck includes a spring arrangement abutting the platform when subject to a weight. A first spring section with a soft characteristic is initially deformed under load, and after a predetermined spring path of the first spring section, a second spring section with a harder spring characteristic is deformable. A sensor detects deformation of the first spring section for generating a release signal. The platform can be folded on a horizontal shaft including a lever arm arranged on a side of the shaft opposite the platform, and abuts the spring arrangement from below which is supported on the truck frame. The first spring section is arranged between a seat for the first spring section and a spacer supported on the second spring section. The spacer acts on the second spring section when the first spring section is initially deformed under a load upon the platform.

A step-stool system that is connected to a shopping cart. The step-stool system includes a platform that has a stowed position and a deployed position. When the platform is in the deployed position, a person may stand on the platform to reach items on higher shelves in a store. When the platform is in the stowed position, the shopping cart can nest with other shopping carts.

A vehicle coupling system includes a first vehicle, a second vehicle, and a tow bar. The first vehicle includes a drive motor configured to propel the first vehicle and a lifting implement configured to support a product for movement. The second vehicle includes a lifting implement configured to support the product for movement. The tow bar is coupled to the first vehicle at a first end of the tow bar and coupled to the second vehicle at a second end of the tow bar opposite the first end. Responsive to the drive motor propelling the first vehicle, the tow bar exerts a force on the second vehicle to maintain a space between the second vehicle and the first vehicle.

A vehicle includes a chassis, a frame, a tractive element, a drive motor, and a cart interface. The cart interface includes a base frame coupled to the frame assembly of the vehicle, and a first and second pin assembly. The first and second pin assembly each include first pin configured to engage a cart and a actuator configured to raise the pin relative to the frame. The first pin assembly also includes a first linear actuator configured to bias the first pin relative to the first linear actuator and to permit relative movement between the first pin and first linear actuator. The cart interface includes a first actuator to reposition the first pin independently of the second pin and is configured to hold the pin in either of a lowered position, a raised position above a lowered position and an intermediate position between the raised and lowered positions.

A vehicle includes a frame, a drivetrain coupled to the frame, a base assembly coupled to the frame, and a lifting implement coupled to and supported on the base assembly. The lifting implement includes a platform, a cradle rotatably coupled to and supported on the platform so that the cradle, a scissor assembly coupled between the platform and the base assembly, and a lift actuator coupled between the base assembly and the scissor assembly. The lift actuator is configured to selectively raise the cradle relative to the base assembly. The lift actuator is a multi-stage telescoping actuator that includes a base stage, an intermediate stage, and an outer stage. The base stage is coupled to the base assembly, the outer stage is coupled to the scissor assembly, and the intermediate stage is arranged between the base stage and the outer stage.

A cart includes a chassis including one or more frame members, one or more casters, a first channel and a second channel coupled to the chassis, the first channel defining a longitudinal axis and the second channel defining a lateral axis. The first channel and the second channel each include a pair of guides each including a first portion and a second portion and a flat member coupling the guide to the frame members. The first portions extend substantially parallel to one another. The second portions are angled to increase a distance between the second portions as the second portions extend away from the first portions.
