Abstract
The invention concerns a foldable trolley for supporting apparatus such as computers, photocopiers or other office of medical equipment while being serviced. A foldable trolley has a base having two sides each having at a top thereof a support member, connecting members connecting the sides so that they can be moved towards and away from one another, wheel members on which the trolley base is mounted, and a detachable trolley top adapted in a horizontal working position to bridge and be supported on the support members when the trolley sides are spaced apart, and in a storage position to be suspended at one side of the folded trolley base. The top has disengageable engagement members for engaging with the support members to retain it in its working position, and the engagement members and support members are engageable and disengageable from one another by a combination of relative sideways translational movement with the top at an acute angle to the horizontal and rotational movement between that angled position and a horizontal position.
