Embodiment Construction

[0032] Reference is now made to the drawings in general, but to the figure 1 , figure 2 and image 3 , a wheeled conveyor device 10 comprising a chassis 12 having a first base member 12a extending in a substantially horizontal plane HP and a longitudinal axis X on which a plurality of wheels 14, 16, 18, 20 lie Around this longitudinal axis X is mounted a suspension system generally designated 22 . Suspension system 22 includes one or more front arms 24a and 24b extending from front portion 12f of chassis 12 in a generally forward direction F and outward O, and each wheel is included herein at its distal end 24d, 24e The caster arrangements 14, 16 are discussed in more detail below. Arms 24a, 24b are each mounted for substantially vertical pivotal movement V about axis A-A or B-B, as image 3 As best shown in , each axis extends at an acute angle with respect to the longitudinal axis X and, in one arrangement, preferably also extends in or parallel to the horizontal plane ...

Abstract

The present invention provides a wheeled conveyance 10 having a chassis 12 having a first base member (12a) and having a longitudinal axis X, a plurality of wheels (14, 16, 18, 20) and a suspension system (22) between one or more of the plurality of wheels (14, 16, 18, 20) and the chassis (12), wherein said suspension system (22) has on or more front arms (24a, 24b) extending in a generally forward (F) and outward direction (O) and being mounted to the chassis (12) for substantially vertical movement about a pivot axis A-A or B-B which extends at an acute angle of alpha relative to longitudinal axis X. The arrangement is more able to absorb shock and more stable than arrangements of the prior art.

Description

technical field [0001] The present invention relates to a chassis with a high mobility suspension system, and in particular to such a chassis and suspension system as can be used, for example, on a children's trolley or the like. Background technique [0002] It is known to provide wheelbarrows and the like with suspension systems to assist the wheelbarrows to pass smoothly over uneven terrain and obstacles such as curbs and steps. An example of a trolley with long suspension arms is shown in GB2470094 which, while providing a potential solution to the problems mentioned above, transmits a display through the suspension in such a way that the suspension is experienced by the occupants of the trolley. The resulting torque reaction. Additionally, when the cart needs to be tilted in an urban environment (such as for a tall barricade), the pressure on the cart arms must lift the rear suspension before the front wheels lift off the ground. This softness is unattractive to many ...
