An overhead storage system for bicycles and objects that weigh approximately 40 to 50 pounds. The stored object is counter balanced by nitrogen gas spring cylinders so as to make the object virtually weightless to the user-operator. The object is stored flat or horizontally against the ceiling of a garage, porch or breezeway so as to be well above headspace and so that floor space is not taken up by the object. The user-operator pulls the stored object down with a cord similar in ease to pulling down a set of attic type stairs. A boom is pivotally connected to a ceiling mount. A first gas spring allows the stored object to move and rotate in an arc from the horizontal ceiling adjacent position to a vertical position approximately thirty inches from the floor. The boom has a lower telescoping tubular sections with a second lower gas spring holding the tubular sections together. The user-operator pulls down on handles connected to the lower tubular section which lowers the object to the floor. A latch locks the system to a down load position. The user-operator can take the object off peg supports on the system to be used. To return the object to a stored position, the above steps are repeated in reverse order. The nitrogen gas spring that causes the boom to rotate about the ceiling mount pivot is a 200 lbs force spring, while the nitrogen gas spring inside the boom that lifts the bicycle in the vertical direction is an 80 to 100 lb force spring. The compound action of the pulley/cable arrangement inside the boom delivers a useable force to lift the bicycle of one half of the nitrogen spring force or about 40 to 50 lbs.

[ What is claimed is:] [1.] An overhead storage lifting device for raising and lowering loads, comprising in combination:a bracket mounted to a ceiling;a single boom member having an upper portion and a lower portion, the single boom member being substantially L-shaped with the upper portion being substantially perpendicular to the lower portion and having a midportion therebetween, the midportion being pivotally attached to the bracket;support means on the lower portion of the boom supporting a frame thereon;a spring pivotally connected to both the upper portion of the boom member and to the bracket, wherein the spring has an expanded position which causes the upper portion of the boom member to pivot about the bracket and raise the frame from a vertical position to a horizontal storage position adjacent to the ceiling;a slidable sleeve connected to the lower portion of the boom member, the sleeve having a raised position with the frame raised above a floor and a lowered position with the frame adjacent to the floor, the support means being attached to the sleeve;a second spring within the lower portion of the boom member, the second spring having an upper end connected to the lower portion of the boom member, and a lower end, the second spring having a compressed position and an expanded position;an upper pulley being connected to the lower portion of the boom member adjacent to the upper end of the second spring;a lower pulley being connected to the lower end of the second spring; anda cable having one end fixed to the slidable sleeve, the cable passing over the upper pulley and passing over the lower pulley to a second end attached to the lower portion of the boom member, wherein the expanded position of the second spring allows the slidable sleeve to be in the raised position with the frame being above the floor, and the compressed position of the second spring allows the slidable sleeve to be in the lowered position with the frame adjacent to the floor.
