Bearing for at least one supporting roller of a carriage, which supporting roller is supported on at least one bearing surface, comprising at least one axle device which can be rotated about at least one rotational axis, at least one rocker which is connected to the axle device such that it is reliably driven, wherein, at an end which lies opposite the axle device, the rocker has at least one first connecting device for connecting the rocker to the supporting roller, at least one spring device which is arranged mechanically between the axle device and/or the rocker on one side and at least one holding device on the other side, wherein a force which forces the supporting roller onto the bearing surface can be built up on the axle device and the rocker by means of the spring device, and at least one damping device, by means of which a rotational movement of the axle device about the rotational axis can be damped, characterized in that the spring device and the damping device are configured in one piece at least in regions by way of at least one torsion spring element which is of rubber-elastic configuration at least in regions.

A device for transporting children. The transportation device includes a base and sidewalls extending therefrom, forming an interior volume. Wheels extend from a lower side of the base and a foldable seat is affixed to at least one sidewall. A pair of doors are hingedly attached to opposing sidewalls, which allow a child ingress and egress from the transportation device. The folding seat allows the transportation device to include an increased capacity to hold objects when not in use by the child.

A foldable or collapsible cart can be oriented in several different configurations to accommodate different loads and transport requirements. In one configuration, the cart may be folded for direct load the back of a vehicle. In another configuration, the cart can operate in lowboy or dolly mode. In another configuration the cart may be used as a hand truck.

The present disclosure relates to a wheel mechanism and a child carrier. The wheel mechanism includes a wheel quick-release mechanism and/or a wheel orientation mechanism. The wheel quick-release mechanism detachably installs the wheel seat onto the frame, and includes a connecting rod having an end connected with the frame and the other end provided with a snapping portion; a receiving hole arranged in the wheel seat for receiving the connecting rod; an inserting channel arranged in the wheel seat and communicated with the receiving hole; an operating member movably arranged in the inserting channel; and a spring. The wheel orientation mechanism orients a wheel seat with respect to a frame and includes an orientating portion on the frame; a receiving slot arranged in the wheel seat corresponding to the orientating portion; and an oriented-locking element interposed into the receiving slot and sliding between a released position and a locked position.

The present invention provides a medical device comprising: a main body; and two or more fixed casters and at least one floating caster, which are connected to a bottom portion of said main body and support said main body, wherein said floating caster is capable of floating in the vertical direction relative to said main body.

A hand truck that includes a carriage, and an elongated frame that connects to a front side of the carriage and is configured to pivot in relation to the carriage. The hand truck also includes a stabilizer plate configured to extend outward from the front side of the carriage to stabilize the hand truck as the elongated frame pivots in relation to the carriage, and to retract inward toward the front side of the carriage.

A suspension system includes a main pivot housing, a swing arm housing, a linkage assembly, and a resilient component. The main pivot housing is disposed on a lower end of a leg of a stroller. An accommodating space is formed inside the main pivot housing. The swing arm housing is pivoted to a side of the main pivot housing. A wheel of the stroller is pivoted to the swing arm housing. The linkage assembly is movably disposed in the accommodating space. The resilient component is disposed between the linkage assembly and a bracket of the stroller. The swing arm housing can be forced to drive the linkage assembly to pivot relative to the main pivot housing for compressing the resilient component, so as to absorb a shock load.

Provided herein is an infant wagon having improved convenience of use, wherein the infant wagon includes a front frame, a rear frame, a support frame, side frames, a front handle frame, and a rear handle frame, and is configured such that the axial distance between front wheels and rear wheels thereof is reduced, whereby it is possible to reduce the burden applied to the arms of a caregiver when the infant wagon is moved or when the direction of the infant wagon is changed, such that the radius of rotation of the infant wagon is reduced, whereby it is possible to easily change the direction of the infant wagon, such that, when the infant wagon is pushed from the rear thereof to move the infant wagon.
