发明名称 Ground mounted appliance with leg joint
摘要 A leg for an outdoors appliance, such as a batting aid having a tethered ball, a basketball hoop assembly, a tennis net, or a table. The leg has upper and lower sections connected by a coil spring. A sleeve driven into the ground receives the leg to a sufficient depth of penetration that the spring is also received within the sleeve. The appliance is thus rigidly supported in the sleeve. The leg, or legs in the case of appliances requiring more than one leg, is manually withdrawn from the sleeve to expose the spring. The spring provides a flexible joint, and the appliance can be inclined toward the ground when the spring has been moved out of the sleeve. This enables service to the item atop the leg or legs. Illustratively, should the tether of the batting aid become wound around the horizontal post to which it is attached, it is easily reached when the appliance is manually inclined. The appliance is readily removed from the sleeve for seasonal storage, and is readily reerected. The sleeve has a cap for safety and to prevent clogging when not in use. The cap may be formed to have a shallow recess, so that the sleeve serves as a golf hole.
