<p>A foot pump comprises a base member and an operating member pivotally connected to the base member. A piston-and-cylinder assembly is connected between the members. In use the user depresses the operating member with his or her foot, thereby causing air to be compressed in and expelled from said assembly. A return spring returns the operating member to its raised position. The base and operating members have complementary pivot pin and hook means which are hooked together to form the pivotal connection between the members. The members are preferably made as unitary plastics mouldings, the pivot pin and hook means being resiliently clipped together.</p> |
