Embodiment Construction

[0033] For the avoidance of doubt, the skilled artisan will appreciate that in this specification the terms "upward", "downward", "front", "rear", "upper", "lower", "width" etc. refer to Substitute the orientation of the parts as found in the example when installed for normal use as shown in the illustration.

[0034] Golf cart 2 in figure 1 shown in . The trolley 2 comprises a chassis 4 housing an electric motor, a gearbox and a rechargeable battery. These items are common to motorized carts and are not shown or described herein. An electric motor powers a pair of rear wheels 6a, 6b rotatably connected to the chassis 4 .

[0035] Extending forwardly from the chassis 4 is a subframe 8 carrying the front wheel assembly 10 and a lower bag support 12 securing the bottom portion of the golf bag in use. The subframe 8 is rotatably connected to the chassis 4 via a chassis rotatable connection 14 . The chassis rotatable link 14 can be locked in an extended configuration (such as...

Abstract

A collapsible trolley includes a main frame, a chassis (4) and at least two wheels (6a, 6b) rotationally coupled to chassis, wherein the main frame includes an upper frame portion (24), a middle frameportion (22) and a lower frame portion (20); a first end of the lower frame portion is coupled to the chassis; a first end of the upper frame portion carries a handle; the upper frame portion is coupled at its second end to a first end of middle frame portion via a first rotational coupling (32); the middle frame portion is coupled at a second end thereof to a second end of the lower frame portion via a second rotational coupling (34); the first rotational coupling includes a first lock arrangement and the second rotational couplings includes a second lock arrangement wherein each lock arrangement has a release configuration in which the rotational coupling is free to rotate and a locked configuration in which the rotational coupling is prevented from rotating; and the trolley further includes a lock release mechanism.

Description

technical field [0001] The present invention relates to a collapsible trolley, and in particular to a collapsible golf trolley. Background technique [0002] It is known to provide collapsible golf carts in a collapsed configuration for storage and transport and an unfolded or unfolded configuration in which the cart is capable of supporting a golf bag. [0003] It is desirable that the folded configuration be as small as possible. However, this typically requires multiple release mechanisms to allow the various components of the cart to rotate, fold and / or release from adjacent components. An example of such a cart is the Motocaddy TM M series trolleys. Such a cart requires five separate release mechanisms to allow the cart to be folded into a relatively compact storage configuration. [0004] Such a large number of release mechanisms can confuse the user as to folding their cart into its storage configuration or reversing the process to use the cart. Failure of one of...
