Abstract
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.

Description
This invention relates to bicycles, and in particular to a device for lifting forty to fifty pound objects such as bicycles from a vertical standing position to a horizontal position adjacent to a ceiling for storage.
Background and Prior Art
Bicycles have had a growing popularity in recent years. When not used bicycles take up valuable floor surface storage space. Bicycles left standing over a long period of time have additional problems such as the rubber tires tend to flatten out over time. Furthermore, these floor standing bicycles can become hazards to persons trying to maneuver about them.
Proposed solutions have been made over the years to store bicycles. For example, hooks with screwable ends have been used to allow the bicycles to be suspended by their wheel rims from ceilings. See for example: U.S. Pat. No. 5,460,274 to Kramer. Similarly, overhead ceiling attached racks also rely on suspending bicycles by their wheel rims. See U.S. Pat. No. 1,232,501 to Colen. A main problem with these hook/rack systems is that the user has to physically lift the bicycle above their head in order to mount the wheel rims onto the hooks/racks. The natural weight of the bicycle itself is a problem to both lift and maneuver. Furthermore, some high ceilings would make it near impossible to both mount the hooks/racks, and maneuver the bicycle wheel rims onto the hooks/racks. Still furthermore, some bicycles with "quick release" wheels have resulted in the bicycle disengaging from the wheel itself. Still furthermore, some light alloy weight bicycle wheel rims are not strong enough to support the weight of the entire bicycle.
Other proposed solutions have incorporated mechanical pulleys and winches. See for example U.S. Pat. No. 5,354,035 to Helgren; and U.S. Pat. No. 5,474,189 to Peterson. However, both systems generally rely on the user pulling a cord and/or using a spring loaded arm to lift the bicycle. The user would be restricted to certain weight limitations on the bicycles by both methods. And the user has to still physically lift and/or lower the weight of the bicycle in these systems.
Still other proposed solutions have relied on wall and ceiling mounted tracks. See U.S. Pat. No. 3,770,133 to Kolker; and U.S. Pat. No. 5,183,162 to Ritzenthaler. However, these devices generally need electrically driven garage-door type motors that require costly electrical power to operate. These track mounted devices take up valuable wall storage space. Furthermore, the wall and ceiling track systems require extensive wall and ceiling assembly and set-up, and would appear to be expensive to manufacture, and sell, making these devices undesirable to average users.
Thus, the need exists for a solution to the above problems.
Summary of the Invention
The first objective of the present invention is to provide an overhead storage device for bicycles in which the user does not have to physically raise or lower the weight of the bicycle.
The second object of this invention is to provide an overhead storage device for bicycles that can be easy to mount on a ceiling.
The third object of the present invention is to provide an overhead storage device for bicycles which does not require an outside power supply such as an electric motor.
The fourth object of this invention is to provide an overhead storage device for bicycles that raises the bicycle from a vertical ground based position to a horizontal position adjacent to a ceiling.
The fifth object of this invention is to provide an overhead storage device for bicycles that does not require wall mounts and thus does not take up wall space.
The sixth object of this invention is to provide an overhead storage device for bicycles that does not lift the bicycle by their rim(s).
A preferred embodiment of the overhead storage lifting device for a bicycle includes a longitudinal boom having an upper end and a lower end, a support means on the lower end of the boom for supporting a bicycle frame, a mount attached to a ceiling and connected to the upper end of the boom, and an upper gas spring cylinder which causes the boom to pivot about the ceiling mount and raise the bicycle from a vertical standing position to a horizontal storage position adjacent to the ceiling. The boom can have a slidable support having an extended position where both wheels of the bicycle are adjacent to a floor, and a retracted position where both the bicycles wheels are vertically raised above the floor and locked in place by a latch. A second gas spring cylinder can be used to move the slidable support from the retracted position to the vertically raised position. The vertically raised raised position can be approximately one to approximately three feet above the floor. Pegs, which can be variably positioned on arms on the slidable support hold the frame of the bicycle. A pull cord is used to move the boom from the horizontal storage position to the vertical standing position.
Further objects and advantages of this invention will be apparent from the following detailed description of a presently preferred embodiment which is illustrated schematically in the accompanying drawings.

A pivot connection 13 attached to an end of an upper gas spring cylinder 10 and has an inwardly directed biased piston 15 with an opposite end 17 pivotally connected to the upper angled boom member 110 of boom 100. Pin 335 allows boom 100 to move in an arc in the direction of arrow X and pivot about pin 335.
FIG. 5A is an enlarged cross-sectional view of the lower gas spring 250 and boom 100 of the overhead storage system 1 of the preceding figures. FIG. 5B is a view of the lower gas spring 250 and tubular member 120 of FIG. 5A along arrow C. Referring to FIGS. 5A-5B, boom 100 includes tubular member 120, a telescoping sliding tube assembly 200 which moves up in the direction of arrow Y1 while lower cylinder 250 moves downward about piston 255 (as seen in FIG. 5A) where the piston rod 255 is a fifteen inch stroke, so that the cylinder 250 moves and travels downward approximately 30 inches. Lower cylinder 250 and piston 255 can be an approximately 80 to approximately 100 lb force nitrogen gas spring cylinder, with the piston 255 normally biased inside cylinder 250. 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.
Referring to FIGS. 5A-5B, telescoping tubular slide assembly 200 includes a hollow cylinder sleeve 210 which moves up and down about longitudinal tubular member 120. Sleeve 210 has an open U-shaped back 212 and opposing rectangular handles 214, 216 attached to the outer sides of sleeve 210 by screw and bolt fasteners 215, 217, respectively. A bent latch lever 218 having one end connected by a bolt fastener 217 to sleeve 210 has an opposite bent tip end 219 which fits within a through-holes 209, 129 which is in both the sleeve 210 and in the outer wall of tubular member 120, respectively. Side plate 220 connects across the lower portion of the U-shaped back opening 212, with a perpendicular plate 222 with a fixed nut 224, having a threaded rod 232 fixed to the end of a cable 235 which passes through a through-hole 127 in the back of tubular member 120. Cable 235 passes around an upper pulley 242 having an axle 243 attached to a clevis 244 which is stationary and fixed to the interior of tubular member 120 by axle 243. Stationary clevis 244 provides an anchor mounting for the non-rod end of gas spring 250. Cable 235 passes down the interior of tubular member 120 and passes around a lower pulley 142 having an axle 143 attached to a clevis 144 attached to the cylinder rod 255 of gas spring 250 and moves up and down with the cylinder rod movement inside 120.
