  • Patent number: 4993156
    Abstract: A spoon or other like hand held implement or utensil comprises a spoon bowl (10) or other load carrying formation fixed to an inner stem (12) which also carries a pendulum weight (22). The inner stem rotates freely within a hollow outer stem (24) which is held in the user's hand and which preferably encloses the weight. In this way the spoon or the like can be used in a self-levelling mode; when the bowl is loaded and with the handle stem held horizontally or approaching horizontal the load will be retained despite any lack of mobility or skill or the part of the user (e.g. a blind or disabled person or young child) or disturbance e.g. when used on a moving ship or vehicle. A brake or other locking device (30,32) can be selectively applied to prevent said rotation and the device may also serve to open the outer stem when shifted to another position.
