Lifting System for Bicycle Storage and Methods Using the Same

1. Field of the Invention

Generally, this invention relates to a bicycle storage system. Specifically, this invention relates to a bicycle storage device for use in an enclosure such as a storage house or a garage or the like to store a bicycle. This invention also relates to a method for storing a bicycle in a garage setting to clear the floor for its intended usage. The designs, requiring little garage area, are particularly suited for storing a bicycle in a tight garage.

2. Background of the Invention

With increasing number of bicycles in a family, storage of bicycles has become a problem. It is desirable to relieve the garage space or storage space in an enclosed garage house for the normal utility to which such structures are intended. It would be further desirable to provide storage means for one or more bicycle within a garage, but without, at the same time, utilizing floor space otherwise needed for the storage of automobiles.

A wide variety of bicycle storage devices have been designed and bicycle storage systems, or a bicycle lifting systems, are common in a market. Among them some are for a single storage of a bicycle while others are for the storage of plurality of bicycles. All the designs have a single purpose: i.e., to store a bicycle or bicycles in a free place above ground within an enclosure, such as a garage or a storage house or the like, so that a usable area in the enclosure can be cleared for automobiles and free access to and from the automobiles and/or for other storage purposes.

As far as the designs themselves, the available bicycle storage devices each have their individual advantages as disclosed in the prior art. A hoistable storage rack for bicycles as described in U.S. Pat. No. 3,924,751, utilizes a support bar having horizontally spaced bicycle hooks mounted to hold a bicycle or a pair of bicycles. The facilitating elements are pulley means. Another example of the previous type of invention is the ceiling cycle rack as described in U.S. Pat. No. 3,782,559. This rack includes a plate removably extended from the ceiling by a plurality of hooks and a pair of J-shaped hangers attached to the plate and laterally adjustable thereon to engage a bicycle frame. In other examples, the bicycle storage system in U.S. Pat. No. 3,872,972 uses a counterweight device and a cable system to lift a bicycle in a garage, while the multiple bicycle support system disclosed in a U.S. Pat. No. 3,907,113 employs a bicycle support mechanism, a couple of pulleys and a cable to complete the bicycle-lifting job in a garage. In general, these systems are operated mechanically and employ a number of pulley means and ago cables, and/or in combination of a support bar or a plate.

A new type of a bicycle storage system was described in U.S. Pat. No. 3,770,133 that was designed on the principle of a garage door opener. However, this is still a mechanical system. According to this invention, the bicycle rack is moved along a track by a cable trained from a winch thus lifting the bicycle and suspending the bicycle at the ceiling area.

Although the previous inventions discussed above have advantages, there also exist some disadvantages. Uses of a pure pulley system and the support bar or the plate may not be convenient for teenagers or elderly people when they try to lift and store the bicycles. The nature of using a pulley design and a cable requires constantly pulling the cable with both hands and thus may cause inconvenience if the users are the teenagers or the elderly. Sometimes accidents may occur if the cable is slipped away from their hands. The design for using a counterweight device is very nice but the system itself requires more materials than necessary and is very complicated for installation. Therefore, it may not be ideal for purposes of simplicity, convenience and inexpensiveness. The design on the principle of a garage door opener to operate a bicycle rack is a comparatively complicated system and may require extensive energy and labor to install.

Therefore, there is a long felt, but unsatisfied need for the invention while the needed implementing arts and elements had long been available. When a device such as a bicycle storage system is designed for use, it needs to satisfy the common requirements for, first of all, simplicity; second, convenience; third, safety; and fourth, easy installation. The problems existing in the field are the mechanical operability, complexity and unavailability of an appropriate electrically operable device. Substantial attempts by those skilled in the art to fill the need of mechanically operated system that is simple and easy and power operated system that is simple to use and easy to install have not been successful, possibly because of failure to understand the nature of problems.

The present invention has some advantages over the prior art. The electrical operation in one of the preferred embodiments greatly advanced the bicycle storage system. It is simple to use, and suitable for any persons, especially those teenagers and elderly. Use of a reel or reels in the present invention is more mechanically advantageous than other means such as a pulley or pulleys exclusively. The lifting components such as the straps do not merely pass through the reel or reels but wind around the reel or reels for easy storage and operation. Thus, it requires less operating space than what the prior art requires and is simple to install. Application of a crank in another preferred embodiment of this invention has added a safety feature to the system and makes it easier to operate. Until the present invention, the bicycle storage systems in the art have not employed such a reel or reels. Such an electrical operating unit has not yet appeared in the art and thus has greatly improved the efficiency and advanced designs of the traditional bicycle storage system. The design of a reel in combination with a spring successfully balanced the bicycle weight and thus the system only employs an inexpensive motor with minimum power supply to fulfill the function. In addition, this system can be inexpensively manufactured and easily installed.

Accordingly, one object of the present invention is to provide a novel, easily operable bicycle storage system using a reel combined with a supporting pivoting element and a cable. Use of such a reel is novel and simple for any bicycle storage system as aforementioned. The present designs are for arranging a bicycle with a view toward utmost simplicity in construction and efficiency in operation and for storing the bicycles off the floor so as to require a minimum amount of floor space in the garage setting.

Another object of this invention is to provide a novel electrical operation for this bicycle storage system. A motor is required to operate the system electrically. The motor may be connected to the reel directly or indirectly and a control unit is also included for simplified operation. Use of a motor in combination with a reel greatly improved the bicycle storage system.

Still another object of this invention is to provide a safely operable mechanical bicycle system that is convenient for any people of different ages. The crank feature for manual operation and the on-off switch function for electrical operation fulfill some aspects of the safety design. The system may be also operated by a remote control unit. In this case, a sensor may be incorporated to the motor to sense a remote signal and thus to control the motor.

Naturally, further objects and advantages of the invention will be readily disclosed throughout other areas of the specification, the drawings and claims.

The basic concepts of the present invention may be embodied in many different ways. The minimum requirement of one embodiment of the bicycle storage system is a reel, a supporting pivoting element, both pivotingly fixed somewhere on the ceiling of an enclosure such as a storage house or a garage or the like by any means of commonly available pivoting elements such as screws or axels, and two straps mechanically connected to the reel.

As can be seen from the drawings and in combination with the specification, the basic concepts of the present invention are illustrated hereby in detail to show some of the preferred embodiments of the present invention. It should be understood that, by providing the drawings, the inventor by no means wants to limit the scope of his invention in any manner.

FIG. 1 shows one embodiment of the present invention in a garage setting. A bicycle (1) is lifted and stored over an automobile by the bicycle storage system (2). This bicycle storage system is operated by an operating unit and this operating unit may be an electrical unit, as illustrated in FIG. 1 and detailed in FIG. 2.

As shown in FIG. 2, the electrical unit may comprise a motor housing (3) to hold a motor (4, shown in FIG. 3). The motor (4) may be controlled by a control unit such as a hanging switch (5). Power is supplied from a power source to operate the motor as expected and the hanging switch can have both the "UP" and "DOWN" commands and, when neither of the two commands are given, a power shutoff mechanism automatically keeps the system in a power off mode. A stretching cord (6) may be attached to the hanging switch to uphold the hanging switch. The system may be also operated by a remote control unit (not shown). In this case, a sensor may be incorporated to the motor to sense a remote signal and thus to control the motor.

As detailed in FIGS. 3 and 5, the motor (4) may be connected to a reel (7) to drive the reel. In one configuration the motor (4) may share the same axle (8) with the reel (7) in a concentric way, thus the motor will drive the reel directly. In another configuration, the motor may be connected with the reel via a circular driving belt (28). Thus, the motor drives the reel indirectly. The reel may be mechanically combined to a first strap (9) and a second strap (10). The first and second straps wind around the reel in either a counterclockwise or a clockwise direction and may also be mechanically combined between themselves. The reel in one configuration may have only one track on it and, in another configuration, the reel may contain two tracks. In the later case, the reel is called a dual reel and the first track (11) may be occupied by the first strap and the second track (12) by the second strap. In one preferred embodiment, at least the first strap may be distantly extended to pass through or over a pivoting element (13) such as a pulley before reaching a bicycle. This design greatly facilitates the movement of the bicycle. For installation convenience, a single unit design may be achieved by simply providing a supporting frame that can hold the motor in the motor housing, the reel and the pivoting element together. In this embodiment, the supporting frame may be designed to serve as a supporting arm (14) to hold the reel and the pivoting element and to facilitate the strap movement. The supporting element can be perpendicular to the reel. For a clear explanation hereon this supporting arm now is defined as the first supporting arm.

In another preferred embodiment, the second strap (10) may also be distantly extended to pass a second pivoting element (15) such as a pulley, as illustrated in FIG. 3. Similarly, a second supporting arm (16) may be added perpendicularly to the reel so that the system may be configured to have the reel in the central region and the first and the second supporting arms located on each side the reel. The first and second pivoting elements can be each located on the distal ends of the supporting arms.

Two bicycle connectors may be needed in each of the above aforementioned designs. The bicycle connectors may be a pair of slings (17 and 18) and may be mechanically connected to the first and second straps separately. The first sling (17) may be connected to a bicycle handle (19) and the second sling (18) to a bicycle seat (20), or vice versa.

The single-piece bicycle storage system can be fixed to the garage ceiling (21, shown in FIG. 2) by any means that a person of ordinary skill will readily utilize. Thus, the system is permanently fixed on the garage ceiling and the bicycle can be lifted above the floor so that the floor space can be cleared for its intended use.

In still another preferred embodiment of the present invention, this device can also be operated by a mechanical unit in addition to its electrical operability. As can be readily understood, to accomplish the mechanical design, an assistant reel (22) as seen in FIG. 4, in replacement of the motor, may be needed. The assistant reel may be fixed on the same axle as the reel (7) in a concentric fashion. Thus, when the assistant reel turns around, so does the reel (7) in the same orientation as that of the assistant reel. A third strap (23), mechanically fixed to the assistant reel, may be wound around the assistant reel and serve as a pulling strap. The winding direction of the third strap may be configured so that, when the bicycle is released from the storage position to the floor, the third step winds around the assistant reel. Opposite to this motion, when the third strap is pulled from the assistant reel, the bicycle is lifted up to a storage position. The second end of the pulling strap may be mechanically fixed to a mechanical crank (24) or other retention element and may be facilitated by a pulley means (25). A retention unit (not shown) may be part of the crank to hold the pulling strap (23) after a bicycle is lifted to a designated elevation above the floor. Both the crank (24) and the pulley means (25) may be fixed on a garage wall (26).

In still another preferred embodiment of the present invention, a second reel (not shown) may be geared to the first reel to jointly lift the bicycle. In this configuration, the first strap may be mechanically attached to and be wound around the first reel in one direction, i.e., either a counterclockwise or a clockwise direction; the second strap mechanically attached to and wound around the second reel in a direction opposite to that of the first strap. This system may be operated by either an electrical unit or a mechanical unit. The motor or the assistant reel only needs to be arranged to connect to the first or the second reel.

In still another preferred embodiment of the present invention, an elastical element may be combined onto the reel, the dual reel or, in a two-reel setting, both the reels, to offset some of the bicycle weight. The elastical element may contain a spring (27). In one-reel configuration, the spring may be mechanically combined to the reel; in a two-reel configuration, a first spring may be combined to the first reel and the a second spring to the second reel. In one preferred embodiment, the springs may be a compression spring, a torsion spring, or some type of biasing element.

The foregoing discussion and the claims which follow describe the preferred embodiments of the present invention. Particularly with respect to the claims, it should be obvious and understood that changes may be made without departing from its essence. In this regard, it is intended that such changes would still fall within the scope of the present invention. It simply is not practical to describe and claim all possible revisions to the present invention which may be accomplished. To the extent such revisions utilize the essence of the present invention, each would naturally fall within the breadth of protection encompassed by this patent. This is particularly true for the present invention since its basic concepts and understandings are fundamental in nature and can be broadly applied. The claims cover not only the apparatus as disclosed in this invention but also the methods on which the invention is based.
