1. Field of the Invention
The present invention relates to a golf bag stand system, and more particularly to a golf bag stand system that stably supports a golf bag in a standing position and that retracts in such a way as to limit and reduce entanglements with other objects such as a golfer's legs when the golf bag is picked up from the standing position.
2. Background and Related Art
Golf bag stand systems are known in the art. These stand systems provide a convenient way for golfers to access contents of golf bags prior to, during, or after a round of golf. Some golf bag stand systems are particularly designed for use by golfers who carry their bags during a round of golf. In such instances, golfers must frequently put down their bags, select and access a golf club or other golf accessory, strike a golf ball, return the golf club (and any accessories used), and then pick up their bags. Additionally, the golfers must carry their golf bags between shots, and typically desire to do so comfortably.
Therefore, retractable golf bag stand systems have been devised that provide a mechanism to support the golf bag and provide access to golf clubs and accessories when a golf bag is set down, and that retract so as not to interfere with carrying the golf bag when the golf bag is picked up. Typical existing retractable golf bag stand systems include a pair of substantially straight legs made of tubular steel, fiberglass, or some other material. The two legs are hingedly attached at or near the top of the golf bag and are typically biased in some way so as to remain close to the golf bag in a retracted position. A push-up plate or other similar device is typically attached at the base of the golf bag so as to be pushed upward when the golf bag is set down in an angled position, or when the golf bag is set down in a vertical position and is subsequently tipped toward an angled standing position. One or more rods or other force-translating members transfers force from the push-up plate to the pair of legs so as to overcome the biasing force holding the legs close to the golf bag, thereby deploying the legs into a bag-supporting position, as is well known in the art.
Existing golf bag stand systems have significant problems. For example, some systems deploy the two legs into a position whereby the two legs are too close to the central axis of the golf bag. In other words, such systems do not provide enough separation between the two legs during deployment to provide a stable support for the golf bag. As may be readily appreciated, the base of the golf bag and the two legs provide a three-point support for the golf bag. When the two legs do not adequately separate during deployment, the golf bag is not adequately supported against a side-to-side tipping motion or force. This means that golfers using such bags may frequently tip the bag over when attempting to retrieve a club or other golf accessory or when attempting to return a club or other golf accessory. The problem is exacerbated on uneven terrain, where it may be difficult to obtain a stable placement of the golf bag.
To overcome these difficulties, some existing golf bag stand systems deploy the pair of legs in a wider stance. This provides more stable support of the golf bag, but such support comes at a cost. Because the legs deploy to a wider-apart position, such systems commonly result in more entanglement issues when the stand system is deployed and especially when the golf bag is picked up from the standing position. Specifically, to pick up a golf bag from a standing position, the golfer typically approaches the golf bag from the side and grasps one or more handles or carry straps of the golf bag and then lifts the golf bag. This action removes pressure from the push-up plate, and the biasing force on the legs causes them to retract. However, the golfer's legs are commonly in the path of the widely-deployed and now-retracting stand system legs. The retracting legs therefore often strike the legs of the golfer picking up the bag. As may be appreciated, golfers commonly do not like the experience of being struck by the retracting legs. Additionally, when the stand system legs strike the golfer's legs, the stand system legs are not able to fully retract and the bag cannot be comfortably carried until the golfer repositions the golf bag to allow the legs to fully retract and then repositions the golf bag again to a comfortable carrying position.
It is not desirable or practical to expect a golfer to simply pick up the golf bag while standing farther to the side of the golf bag to avoid entanglement issues, as this places much greater strain on the golfer's back and muscles. However, golfers who use such bags commonly do this, often from an unconscious adaptation to avoid entanglements, placing themselves at greater risk for injury or muscle fatigue.
During an 18-hole round of golf, a par-level golfer may expect to set down his or her golf bag into the standing position and to pick up his or her golf bag from a standing position a minimum of approximately 54 times. Additional times where it may become desirable or necessary to set down and pick up the golf bag may include times when a golfer is waiting for a playing partner to take a golf shot, or when waiting for other golfers in front of the golfer to complete a hole or move along. As most golfers who carry their own bags are not par golfers, most golfers will set down and pick up their bags significantly more often. The problems with existing stand systems are therefore exacerbated by the frequency with which such problems are encountered. Either the golfer must be careful in placing, accessing, and picking up an unstable bag, or the golfer must put up with repeated potential entanglement situations.
Implementation of the invention provides a golf bag stand system whereby the legs of the stand system deploy in an arcuate path. The arcuate path permits the legs of the golf bag stand system to be widely deployed to support the golf bag, while minimizing entanglement issues during deployment and retraction of the legs of the stand system. This is achieved because the arcuate deployment keeps the legs closer to the center line of the bag during a greater period of the deployment/retraction, with the sideward/outward movement of the legs occurring at the end of leg deployment and at the beginning of leg retraction. This may be achieved by hingedly connecting the legs to the golf bag whereby each hinged connection of the legs to the golf bag has an axis of rotation that is inclined toward the center of the golf bag when the golf bag is in an upright vertical position. The legs of the golf bag include a bend or jog that permits the inclined axis of rotation while keeping the legs close to the golf bag when in the retracted position.
Further implementation of the invention provides a golf bag stand system whereby the legs of the stand system are automatically and securely retained in a fully-stowed position when the golf bag is being carried. This may be achieved by the use of magnets and the like to apply an attractive magnetic force between a portion of the golf bag and a portion of the legs of the stand system. Implementations of the invention are described below in conjunction with the attached drawings.
The objects and features of the present invention will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only typical embodiments of the invention and are, therefore, not to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
A description of embodiments of the present invention will now be given with reference to the Figures. It is expected that the present invention may take many other forms and shapes, hence the following disclosure is intended to be illustrative and not limiting, and the scope of the invention should be determined by reference to the appended claims.
Although the following description focuses on a golf bag stand system, it is envisioned that the embodiments of the invention may be advantageously applied to other bags and carrying devices. By way of example and not limitation, it is envisioned that embodiments of stand systems similar to those described below may be used with baseball bag and equipment bags, soft-sided and hard-sided musical instrument bags and cases, travel bags, including rolling travel bags, and any other carrying device where a user may find it convenient to have a stand system of the type described below. Therefore, in the description and claims, the word “bag” standing alone should be interpreted as embracing any and all types of bags and carrying devices.

Although not shown in the stylized representations of
The golf bag 10 may also include a stand system to permit a golfer to set the golf bag 10 down in an angled position to permit easy access and retrieval of golf clubs and other accessories from the golf bag 10. The stand system typically includes a pair of legs 14 connected to the golf bag at a pair of leg attachment points 16. Each leg 14 includes a proximal end attached to the golf bag 10 and a distal end that contacts the ground when the legs are deployed and the golf bag 10 set down. As is known in the art, each leg 14 may include several components or parts, including an attachment member that attaches to one of the attachment points 16, a long leg member attached at one end to the attachment member, and optionally a ground-contacting member attached at the opposite end of the long leg member. Each of the various members of the legs 14 may be made of various materials, including metal such as tubular steel, aluminum, titanium, or other alloys, plastic, fiberglass, composite materials, graphite, and/or carbon composites. Alternatively, two or more of the components of the legs 14 may be manufactured as unitary pieces. As is also known in the art, the stand system may include a push-up plate at the base of the golf bag 10 and one or more rods or force-translating members to transfer force from the push-up plate to the legs 14 to cause the legs 14 to deploy when the golf bag 10 is set down and/or tipped from a vertical position to an angled position.
As discussed above, the legs 14 may be attached to the golf bag 10 at the pair of leg attachment points 16. The leg attachment points 16 (and the corresponding attachment members of the legs 14) may take many differing shapes and may be made of similar materials to the various members of the legs 14. Typically, the leg attachment points 16 include some structure that is fixedly attached to a frame or other supporting structure of the golf bag 10, and the structure of the leg attachment points 16 typically provides a hinged-type connection between the leg attachment points 16 and the legs 14. Specifically, whatever the shape or structure of the leg attachment points 16 and the attachment members of the legs 14, each of the leg attachment points 16 will provide an axis of rotation 18. Each leg 14 connected to the golf bag 10 deploys and retracts by rotating about the axis of rotation 18 for that leg 14. In some instances, there may be some play allowed about the axis of rotation 18 in the connection between the leg 14 and the attachment point 18, but the bulk of the movement of the leg 14 during deployment and retraction of the leg 14 occurs by hinged or rotational movement around the axis of rotation 18.
Embodiments of the invention provide for wide-spaced deployment of the legs 14 while simultaneously reducing the problem of entanglement during deployment or retraction by modifying the axes of rotation 18 as may be seen in
The angle of inclination 20 may be of varying angles from horizontal (when the golf bag is in a vertically-disposed position) so as to achieve the advantages discussed herein, including angles of 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 60 degrees, 75 degrees and angles between these angles and ranges of angles including these angles. Because of the advantages discussed herein by providing the axes of rotation 18 with the angle of inclination 20, the axes of rotation 18 may be more close to parallel to each other (i.e. more obtuse to one another than in
As may be appreciated by reference to
As may be appreciated, any shape of the leg 14 that transitions between the leg attachment point 16 and the lower portion 30 is consistent with the embodiments of the invention. By way of example, reference is made to
Providing the axis of rotation 18 with the angle of inclination 20 and providing the leg 14 with a jog 26 or other shape as described herein alleviates the problems inherent in existing stand systems. Specifically, wide deployment of the legs 14 may be achieved with reduced entanglement issues. This is illustrated in
Thus, the structure described herein provides for a method of deploying and retracting the legs 14 of a golf bag stand system that includes providing the legs 14 in a retracted position proximate the golf bag 10, wherein the proximal ends of the legs 14 are attached to the golf bag 10 near an upper open end of the golf bag. The method further includes deploying the legs 14 into a deployed position, wherein the distal ends of the legs 14 are separated from each other to provide stable support of the golf bag, and wherein the legs 14 travel along the arcuate path 34. The method also includes retracting the legs 14 along the arcuate path 34. The method provides stability of the golf bag while reducing the risk of unwanted entanglements of the legs 14 during deployment or retraction.
The embodiments of the invention also provide for a method for attaching the legs 14 of a golf bag stand system to a golf bag so that the distal ends of the legs 14 will deploy and retract in the arcuate path 32. The method includes providing a leg attachment point 16 on the golf bag 10 near the upper end of the golf bag 10 and providing legs 14 having a lower portion 30 configured to rest along the sides of the golf bag 10 when the legs 14 are in a retracted position. The method also includes attaching the legs 14 to the leg attachment points 16 so that each of the legs 14 is hingedly attached to the golf bag whereby each leg 14 rotates about the angle of rotation 18 at the leg attachment point 16 and whereby the angle of rotation 18 is inclined toward the vertical plane of symmetry an angle of between 15 and 75 degrees from horizontal when the golf bag 10 is in a vertical position. The embodiments of the invention embrace any other method of attaching the legs 14 to the golf bag 10 so that the legs 14 will travel in the arcuate path 32, including systems of gears.
One of skill in the art will readily appreciate that the exact arcuate path 32 of the legs 14 during deployment may be varied by varying the angle of inclination 20, the distance between the leg attachment points 16, and the angle between the axes of rotation 18 of the leg attachment points 16 when viewed along the vertical axis of the golf bag 10 (e.g., compare
One of skill in the art will also readily appreciate that any form of connection of the legs 14 at the leg attachment points 16 that provides the axes of rotation 18 and substantially hinged or rotational movement of the legs 14 about the axes of rotation 18 will fall within the embodiments of the invention. By way of example and not limitation, the axis of rotation 18 may be provided by a rod on either of the leg 14 or the leg attachment point 16 and a corresponding slot, hole, receiver, clamp, or other member on the other of the leg 14 and the leg attachment point 16. Alternatively, both the leg attachment point 14 and the proximal end of the leg 14 may be provided with a hole that receives a separate rod or rivet that provides the axis of rotation 18. In other embodiments, a separate hinge may be provided and attached to both the leg attachment point 16 and the leg 14 to provide the axis of rotation 18. Any such method or other known method of providing a connection having the axis of rotation 18 may be used. It is preferred that the method or mechanism so used be light and durable to allow the golf bag 10 to be carried and to be used without breakage for an extended period of time.
At least some embodiments of the invention also address problems with the legs 14 of the golf bag 10 dangling, bouncing, or having some other movement from the fully-retracted or stowed position, as commonly occurs in existing golf bag stand systems. In existing systems, when the legs are in their stowed position and the golf bag is being carried, the bag is typically carried in a somewhat horizontal position with the legs facing downward. In this position, the golfer's walking motion causes cyclical up-and-down motion and force to be applied to the golf bag and legs. This may cause the legs to move from their fully-stowed position, causing a risk of entanglement, a risk of the partially-deployed legs hitting the golfer carrying the golf bag, and risks of noise and vibration.
Some embodiments of the invention prevent or reduce this problem by automatically securing the legs 14 to the body of the golf bag 10 when the legs 14 are in the fully-retracted or stowed position. This may be provided by a means for securing the stowed legs 14 to the bag. One means for securing the stowed legs 14 to the golf bag 10 is illustrated in
As may be appreciated, when the legs 14 are retracted into a position that is stowed or nearly stowed, the magnetically-interacting portions apply a force to the legs 14, causing the legs 14 to more fully move into the fully stowed or retracted position. The magnetic force will also keep the legs 14 in the fully-retracted/fully-stowed position, thereby avoiding the aforementioned problems that may be encountered with unrestrained stowed legs 14. The strength of the magnets, and thereby the attractive magnetic force may be varied or chosen so as to automatically and securely stow the legs 14 in the fully-stowed position, without requiring that undue force be applied to the legs 14 to deploy the legs.
In embodiments where the bracket 34 is attached to the one or more push rods 36, it will be appreciated that when the golf bag 10 is set down or tipped so as to apply force to the push-up plate, it will cause a vertical (as viewed in
In some embodiments, the magnets 38 or other magnetically-interacting portion(s) may be disposed on a back surface or inside of the bracket 34 away from view. Although such a disposition may require stronger magnets to achieve the same magnetic force, the result may be visually appealing.
In other embodiments, the magnets 38 may be directly attached to an internal or external frame of the golf bag 10. In still other embodiments, the magnets 38 may be sewn, glued, or stitched into the material of the golf bag 10 or into a pocket made in the material of the golf bag 10 at an appropriate location so as to provide the attractive magnetic force. The vertical placement of the bracket 34, magnets 38 without a bracket 34, or other magnetically-interacting portions may be varied for aesthetic or functional purposes and remain within the scope of the described embodiments of the invention.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
