  • the present invention relates to a collapsible trolley and in particular to a collapsible golf trolley. It is known to provide collapsible golf trolleys which have a collapsed configuration for storage and transportation and a non-collapsed or expanded configuration in which the trolley is able to support a golf bag.
  • MotocaddyTM M series of trolleys Such trolleys require five separate release mechanisms to permit the trolley to fold into a relatively compact storage configuration. Such a high number of release mechanisms can be confusing for a user to collapse their trolley into its storage configuration or to reverse the process to use the trolley. It also significantly increases the chance of product failure if one of the release mechanisms fails and it increases the production and assembly costs. It is therefore desired to provide a collapsible trolley which has a relatively compact collapsed configuration for storage and transportation, which is easier to operate, has a lower risk of product failure and/or reduced production and assembly costs.

Thus, the lock release mechanism may be located adjacent to the first or the second rotational coupling.
