Description

FIELD OF THE INVENTION

The invention relates generally to a backpack for carrying golf clubs, and more particularly to, a golf club backpack that may be worn by a person that may be worn in transit and on the golf course.

BACKGROUND OF THE INVENTION

Traditional bags for carrying sports equipment are bulky and heavy. For instance, golf bags may be utilized for carrying golf clubs and golf accessories. A golf bag may also be used to store golf clubs and accessories in between golf sessions, for example, either in the trunk or in a separate location, for example, a garage. A golf bag may also be utilized to protect the sporting equipment during transport, for example, as checked in baggage on a plane. A golf bag may also be carried or transported around the golf course, for example, on a golf cart or carried during play.

However, some golfers desire to travel to, and from, the golf course, using mode of transportation other than an automobile or truck, such as a motorcycle or bicycle. Traditional golf bags are generally too heavy and bulky to be transported on a motorcycle. Furthermore, in a traditional golf bags, the golf clubs are generally carried upright or vertical in a single tube-shaped container. Such an arrangement is generally too long to be carried or transported on a motorcycle or bicycle.

The present invention is aimed at one or more of the problems identified above.

With reference to FIGS. 6D-6G, the first and second lever linkages 102D, 102F pass through apertures 82 in the middle member 28B of the frame 28 of the first cartridge 18. A first key aperture 83 is located on an outer surface of the middle member 28B (FIG. 6E). The first lever linkage 102D is positioned within the first key aperture 83 and coupled thereto via a friction fit, fastener, and/or adhesive. The second axle 102E passes through an aperture 84 within one side of the middle member 30B of the frame 30 of the second cartridge 20. A second key aperture 85 is located on an inner surface of the middle member 30B (FIG. 6G). The second lever linkage 102F is positioned within the second key aperture 85 and coupled thereto via a friction fit, fastener, and/or adhesive.

In the latched position the first and second cartridges 18, 20 are vertical. In this position the spring mechanism 104 is compressed with stored energy. Once unlatched, the spring mechanism 104 extends, which causes the symmetrical linkage 102 to move. The motion of the extension is damped to a controlled velocity. The movement of the symmetrical linkage 104 rotates the first and second axles 102C, 102E in opposite directions resulting in rotation of the first and second cartridges 18, 20. As the spring mechanism 104 extends and the axles 102C, 102E turns, the first and second cartridges 18, 20 are deployed to the riding or cross positions and the spring mechanism 104 is in a fully extended state.

With reference to FIG. 6C, the spring mechanism 104 has a first end 104A and a second end 104B. The first end 104A is coupled to the base 12. A bearing 108 connected to the second end 104B of the spring mechanism 104 allows the second end 104B to move relative to the base 12. The symmetrical linkage 102 further includes a pair of rotational linkages 110, 112 coupled to the second end 104B of the spring mechanism. Each of the rotational linkages 110, 112 are connected to one of the first and second axles 102C, 102E. As the spring mechanism 104 expands and retracts, the rotational linkages 110, 112 impart rotational movement to the respective axle 102C, 102E.

In one aspect of the present invention, the spring mechanism 104 maintains some load on the first and second cartridges 18, 20 maintaining the first and second cartridges 18, 20 in the cross position. In motion or use, if the rider encounters a large bump, the spring mechanism 104 will act as a damper and allow the first and second cartridges 18, 20 to rotate slightly, helping to absorb any shock loading and minimize transfer of shock-load to the rider.

In one embodiment, the spring mechanism 104 may be a gas spring. However, it should be noted that other types of mechanisms may be used, including, but not limited to clock springs, extension springs, compression springs, rotary dampers, etc. . . .

In some embodiments, the unfolding and latching mechanism 100 is a push-push latch. In other words, when the user pushes the first and second cartridges 18, 20 towards the upright positions, the unfolding and latching mechanism 100 latches. To unlatch, the user may simply push again, slightly over center, and then the first and second cartridges will deploy. The latch may be built within the gas spring. However, it should be noted that other types of push-push latches could be utilized.

Fourth Embodiment

With reference to FIGS. 7A-7C, in which like parts are numbered the same as in the first embodiment, a backpack 10 configured to carry sporting equipment, such as a golf clubs, according to a fourth embodiment is shown. The backpack 10 of the fourth embodiment includes an unfolding and latching mechanism 100 similar to the unfolding and latching mechanism 100 of the third embodiment. The unfolding and latching mechanism 100 includes a symmetrical linkage 102 with first and second axles 102C, 102E with first and second lever linkages 102D, 102F that operate in a similar manner (see FIGS. 7B-7E) (although arranged or positioned 180 degrees) and a spring mechanism 104.

As shown, the unfolding and latching mechanism 100 of the fourth embodiment includes a rip-cord style deployment mechanism 114. With reference to FIGS. 7B-7C, the unfolding and latching mechanism 100 is shown in a stowed state, which corresponds to the vertical positions of the first and second cartridges 18, 20. The spring mechanism 104 is configured to bias the symmetrical linkage 102 towards the stowed state. A deployment mechanism 114 includes a pull handle 116, a detent mechanism 118, and a control cable 120. The pull handle 116 and the detent mechanism 118 may be affixed to the shoulder strap of the harness 14. The pull handle 116 has two positions: an extended position (see FIG. 7E) and a retracted position (see FIG. 7C). The pull handle 116 is connected to one end of the cable 120.

The control cable 120 operates a slider 122, which in turn is affixed to the symmetrical linkage 102. As discussed above, the symmetrical linkage 102 drives the first and second axles 102C, 102E in opposite rotational directions. To move the first and second cartridges 18, 20 from the upright positions to the cross positions, the pull handle 116 is pulled from the stowed position to the extended position resulting in movement of the symmetrical linkage 102 thereby causing the first and second axles 102C, 102E and the first and second cartridges 18, 20 to rotate towards the cross position.

A damper may be utilized in parallel with the spring mechanism 104 to control the motion velocity. In the retracted position, the pull handle 116 is closest to the rider's back, the control cable 120 is relaxed, the spring mechanism 104 is extended, and the cartridges 18, 20 are in the deployed or cross positions for riding. The spring mechanism 104 maintains some load on the cartridges 18, 20, keeping them in the cross position. If the rider encounters a large bump, the spring mechanism may allow the cartridges 18, 20 to rotate slightly, helping to absorb any shock loading and minimize transfer of shock-load to the rider.

To move the cartridges 18, 20 into the vertical position, the rider grasps the pull handle and pulls towards their chest, extending the cable and nesting the handle into its outer detent (see FIG. 7E). This motion compresses the spring mechanism 104, and the result is that the cartridges are latched into their vertical positions for playing golf.

In one aspect. The spring mechanism 104 of the fourth embodiment includes a compression spring. However, there are numerous types of spring/damper arrangements that could be utilized (such as a clock spring, extension spring, rotary, gas spring, damper, etc).

The foregoing invention has been described in accordance with the relevant legal standards, thus the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and fall within the scope of the invention.
