Embodiment Construction

[0061] with reference to the attached figure 1 and figure 2 , which provides a trolley frame for a trolley, indicated generally at 10, which is formed from a plurality of hollow tubular frame members. Each frame member is pivotally connected to the other and is made of a lightweight yet strong material. Such as figure 1 and figure 2 As shown, two parallel outermost frame members (hereinafter referred to as main frame members 12 ) extend in a first diagonal direction when the cart is in the open configuration. The main frame members 12 are spaced apart from each other so as to define a space therebetween in which a child receiving device, such as a seat or bassinet, may fit. The mechanism for assembling the child receiving device will be described in more detail below. The main frame member 12 may include two tubular sections 12a, 12b telescopically engaged such that the first section 12a is slidably received within the second section 12b. In this way, the main frame me...

Abstract

A foldable stroller (10) comprising a main frame (12) for supporting a child-receiving device; a rear wheel assembly coupled to the main frame (12), comprising an elongate support leg (20) carrying arear wheel (32) at a first end, and being pivotally coupled a second end to a first end of said main frame (12); a front wheel assembly comprising front wheels (28); a linear drive mechanism (25) foreffecting folding and unfolding of the stroller (10), upon actuation, said linear drive mechanism (25) comprising a linear actuator (24) coupled to a motor and selectively linearly movable by an actuation device (24); and a linkage assembly, coupled between the rear wheel assembly and the main frame (12), said linkage assembly comprising a first link arm (16) pivotally coupled to the support leg (20) at a position along its length and a second link arm (13) pivotally coupled to the main frame (12) at a position along its length, the first (16) and second (13) link arms being connected togetherby a pivotal joint (18); wherein the linear actuator (24) extends from the front wheel assembly to said pivotal point (18) between said first (16) and second (13) link arms and configured, upon actuation, to move in a direction away from the front wheel assembly to fold the stroller (10) and in a direction toward the front wheel assembly to unfold the stroller (10) for use.

Description

technical field [0001] The present invention relates to a foldable trolley. In particular, although not necessarily exclusively, the present invention relates to a collapsible cart with an automatic folding mechanism. The invention also relates to a collapsible bassinet for use in a collapsible trolley. Background technique [0002] Collapsible strollers are well known in the art, particularly when the user may be traveling, or when the stroller is not being used and thus stored away. Such carts typically include a manual mechanism that requires the user to manually complete several steps to transition the cart between a fully collapsed configuration and a fully unfolded configuration. Typically, such steps will require both hands of the user in order to complete successfully. This is inconvenient and frustrating for the user, especially if they also have young children who may get lost during the procedure or babies who need to be held. There is also a risk that the ste...
