The various embodiments of the present invention relate generally to heavy bags and equipment carriers, and more particularly, to golf bags with an adjustable handle for balancing a loaded golf bag, making the loaded golf bag easier to transport.
Most sports and athletic activities require a variety of equipment. This equipment is often times carried by athletes to and from the site where activities take place. Equipment is often heavy and bulky, requiring some form of transporter to carry conveniently. For example, golfers typically use golf bags to store and transport golf clubs and other golfing equipment.
As most golfers know, playing golf requires numerous clubs because each club has different hitting characteristics and an assortment of quality golfing equipment. Rather than carrying a full set of golf clubs by hand, golf bags enable golfers to easily transport golf clubs and golf equipment while playing golf. Golf bags also allow golfers to store their equipment in one place and easily transport their golf equipment when traveling. Indeed, most golfers utilize golf bags to store golfing equipment such as golf balls, shoes, attire, and refreshments consumed by golfers when playing golf. While golf bags enable golfers to store many items, the weight from these items can cause golf bags to become heavy and difficult to transport by hand. In addition, the uneven mass distribution of the items stored in a golf bag may cause different portions of a golf bag to weigh more than other portions thereby making golf bags harder to transport.
The most common manner of carrying a golf bag is by lifting it by a handle located near the top of the bag. While these conventional golf bag handles enable golfers to carry loaded golf bags, there are drawbacks associated with them. One drawback is that these handles do not adjust to balance the load of a golf bag when carried. Many golfers who have carried golf bags have experienced the uneven weight of a loaded golf bag that makes carrying heavily loaded golf bags challenging. This can lead to various shoulder, arm, and back injuries, especially in golfers who may be elderly or those who have trouble carrying heavy golf bags. This problem has been recognized, but no adequate solution has been developed until now.
An example of conventional attempts to remedy this problem can be found, for example, in U.S. Patent Application Publication No. 2006/0249552 to Chang. Chang discloses a golf bag with an angled handle. The handle in Chang, however, is fixed to the body and incapable of adjusting to the different loads of the bag. Until now, there has remained a need for an adjustable golf bag handle that would allow a user to comfortably carry the bag.
The various embodiments of the present invention provide an equipment carrier with an adjustable handle that solves the above mentioned problems and others associated with conventional equipment carrier handles. The particular disclosed embodiments of the equipment carrier are directed to a golf bag. Other embodiments of the equipment carrier, however, can be used for carrying a variety of equipment, such as bats, hockey sticks, skis, etc. Various embodiments of the invention are to an adjustable handle for a golf bag. The handle advantageously adjusts and balances the load of a golf bag. In particular, the handle is designed such that it remains substantially parallel to the plane of the ground as the center of mass of the bag is balanced directly below the handle.
The exemplary embodiments of a golf bag comprise a body defining an interior and an exterior and a handle having a first portion and a second portion, the first portion in pivotal communication with the body, the second portion in retractable communication with the body.
These and other features as well as advantages, which characterize various exemplary embodiments of the present invention, will be apparent from a reading of the following detailed description and a review of the associated drawings.

Embodiments of the present invention provide a golf bag with an adjustable handle. The golf bag with an adjustable handle can comprise multiple parts or members that are pivotally and rotatably connected so the adjustable handle can move in response to the mass of a loaded golf bag. The adjustable handle enables golfers to easily manually transport a golf bag that may be loaded unevenly due to the uneven weight of golf clubs and positioning of storage compartments on a golf bag. A golf bag with an adjustable handle according to embodiments of the present invention can automatically adjust so that the mass of the golf bag is balanced about the handle of the golf bag. Thus, the embodiments of the present invention provide a golf bag that is easy to carry because the user does not have to worry about carrying an uneven golf bag. In addition, the embodiments of the present invention also assist in preventing injury from carrying unevenly weighted golf bags.
Physics and geometry determine the most comfortable, natural, and ergonomic manner for carrying objects using a handle. The exemplary position for carrying an object is with the arm straight at the user's side, grasping a handle substantially parallel to the plane of the ground, and the center of mass of the object directly below the handle. Such a position is not possible with traditional golf bags, because the handle is substantially parallel to and located near the top of the body of the bag, and the center of mass of a loaded bag is near the bottom. In practice, when a bottom heavy golf bag is picked up by a conventional handle, the body of the golf bag and consequently the handle are at a substantial angle to the plane of the ground. This puts strain on the wrist and requires the user to bend his/her elbow. The natural response is to attempt to level out the handle by twisting it, which moves the center of mass of the bag from directly below the handle, generating a moment of force about the handle. This creates great strain in the user's wrist and arm.
There are two options for overcoming this situation. One is changing the center of mass of the golf bag and another is adjusting the handle. Changing the center of mass would be highly impractical, if not impossible, since the center of mass depends on the weight, shape, and position of the objects loaded in the bag. Changing the angle of the handle in relation to the body of the bag in response to different loads is feasible, and is accomplished by the various embodiments of the present invention.
Various exemplary embodiments of the invention are directed to a golf bag with an adjustable handle. Such exemplary embodiments provide a comfortable and ergonomic means for carrying a golf bag. The handle preferably remains substantially parallel to the plane of the ground and balances the load of the bag evenly in the user's hand. At the same time, the center of mass of the loaded golf bag can be balanced directly below the handle. This advantageously provides an optimal carrying arrangement that does not place stress on the wrist, arm, or elbow, and enables a natural carrying position.
According to some exemplary embodiments, when a golfer picks up a bag with an adjustable handle, the top of the handle pivots and the bottom of the handle extends away from the bag. This changes the angle between the handle and the body of the bag. Further, the center of mass of the bag will naturally fall directly below the handle due to handle configuration. As a result, the optimal carrying position will be achieved with the handle substantially parallel to the ground and the center of mass of the golf bag directly below the handle.
In an exemplary embodiment, a golf bag comprises a body defining an interior and an exterior, and a handle having a first portion and a second portion. An attachment member is in communication with the first portion of the handle and the body at a first attachment point. A retractable member is in communication with the second portion of the handle and the body at a second attachment point. The first portion may pivot or rotate about the attachment member relative to the body. The second portion may move away from and toward the body, with the assistance of the retractable member.
Referring now to the figures,
A handle 30 is provided for picking up the golf bag 10. The handle 30 comprises a first portion 31 and a second portion 32. The handle 30 is preferably contoured to fit comfortably in the user's hand. The handle 30 is preferably rigid or semi-rigid and constructed from metal, plastic, rubber, or other suitable materials so that it does not bend or deform in the user's hand under the weight of the bag. The handle 30 preferably is wrapped or covered with a foam, leather, rubber, fabric, or other padded material to improve carrying comfort.
An attachment member 40 is in communication with the first portion 31 and the body 20 at a first attachment point 41. The first attachment point 41 is preferably at or near the top region of the body 20. The first portion 31 preferably pivots or rotates about the attachment member 40. The attachment member 40 is preferably affixed to the exterior surface or the frame of the bag 10 at the first attachment point 41. In other contemplated embodiments, the attachment member is integral with either the handle 30 or the body 20. In further contemplated embodiments, the attachment member 40 may be omitted and the first portion 31 may communicate directly with the first attachment point 41.
A retracting member 50 is in communication with the second portion 32 and the body 20 at a second attachment point 51. The second attachment point 51 is preferably spaced apart from the first attachment point 41. It can be located at any of a plurality of points on the exterior or interior of the body 20, below the first attachment point 41. The illustrated location of the second attachment point 51 is exemplary and not meant to be limiting. The retracting member 50 is preferably elastic. The elasticity of the retracting member 50 enables retractable communication between the second portion 32 and the body 20. Retractable communication can mean, but is not limited to, the second portion 32 extending away from the body 20 as the handle 30 is grasped, and retracting proximate to the body 20 as the handle 30 is released as the retracting member 50 decreases in length or contracts. In other contemplated embodiments, the retracting member 50 can be rigid and coupled to a spring, a winding reel, or other mechanism capable or retracting a strap.
According to an exemplary embodiment, the handle 30 can adjust relative to the body 20. The handle 30 adjusts by moving between two preferable positions: the retracted position and the extended position. When the bag 10 is at rest (i.e., not being carried) the handle 30 is in the retracted position.
When the bag 10 is being carried the handle 30 can be in the extended position.
When the bag 10 is set down and the handle 30 returns to a resting state, the retracting member 50 decreases in length and the second portion 32 is retracted back to a position proximate to the body 20. In this manner, the handle 30 transitions between an extended position and a retracted position.
According to an exemplary embodiment, when the bag 10 is carried, the handle 10 is in an extended position.
In an exemplary embodiment the attachment member 40 may be a strap 90. An exemplary embodiment of the bag 10 with a strap 90 is illustrated in
Other contemplated embodiments may not employ a strap as an attachment member 40. For example, the attachment member 40 may be a block formed from plastic, metal, rubber, or another material. The attachment member 40 may pass through a first slot 100. In further embodiments, the first slot 100 may be located on the attachment member 40. In such embodiments, the first portion 31 pass through the first slot 100. In the contemplated exemplary embodiments, the communication between the first portion 31 and the attachment member 40 is pivotal.
In an exemplary embodiment, the attachment member 40 can be a set of brackets as illustrated in
The distal ends 141 ″ and 142″ of brackets 141, 142 are attached to the first portion 31. Preferably, the distal ends 141″, 142″ of the brackets 141, 142 and the first portion 31 comprise coaxially aligned bores. Through these bores a pin, bolt, screw, or other attachment member may pass. The brackets 141, 142 and the first portion are rotatably coupled. As a user lifts the bag 10, the first portion 31 and distal ends 141″, 142″ of the brackets 141, 142 rotate relative to each other. Preferably substantially simultaneously, the proximate ends of the brackets 141, 142 rotate relative to the body 20.
In a resting position, the brackets 141, 142 are preferably attached to the body at points above the first portion 31. As a result, rotation of the brackets 141, 142 causes the handle 30 to move away from the body as well as vertically relative to the body axis 60. This enables for improved adjustment of the handle under different load conditions of the bag 10.
In an exemplary embodiment of the invention, the retractable member 50 is a retracting strap 120. The exemplary embodiment comprising the retracting strap 120 is illustrated in
In other contemplated embodiments, the retracting strap may comprise a hole or opening though which the second portion 32 passes and attaches. Other contemplated embodiments include integrating the retracting strap 120 with a portion of the handle 30. For example, if the handle 30 is formed of rubber, the retracting strap may be bonded within the strap. Embodiments are contemplated wherein the handle 30 and retracting strap 120 are pivotally connected or rigidly affixed to each other.
In an exemplary embodiment, the retracting member 50 is coupled to the bottom portion of the interior of the body 20. As illustrated in
In an exemplary embodiment, the retracting member 50 connects to an elastic member 51. In some embodiments, elastic member 51 may be sewn to the retracting member 50. In other embodiments, the elastic member 51 may pass through a loop formed by the bottom end of the retracting member 50. In other contemplated embodiments, the elastic member 51 may connect to the retracting member 50 using a buckle, clasp, ring, or other suitable fastening or connecting element. The elastic member 51 is preferably constructed form an elastic material, such as a bungee cord. The elastic member may be constructed of rubber, rubber over layed with fabric or material, cotton or nylon blended with a stretchable fabric, or another suitable material. The elastic member 51 preferably comprises two legs 52 and 53. The legs 52, 53 preferably attach to different point located at or near the bottom region of the interior of the body 20.
In other contemplated embodiments, the retracting member 50 connects directly to the interior of the body 20. For example, the bottom section of the retracting member 50 preferably splits into a first segment and a second segment, both of which connect to the frame or interior of the body at separate points. In other contemplated embodiments the retracting member 50 does not split into two segments and connects to the interior of the body at a single point. It is also contemplated that the retracting member connects to the interior of the body 20 at any point between the aperture 130 and the bottom of the body 20.
A handle is provided and the top of the handle is preferably pivotally connected to the attachment member 230. The handle is preferably contoured to ergonomically fit the user's hand. The handle preferably may be constructed from metal, plastic, leather, nylon, or another suitable material. The handle is preferably wrapped or padded with foam, leather, fabric, or another suitable cushioning material. The bottom of the handle is retractably attached to body such that the bottom of the handle can extend away from the body and be pulled back to the body 240.
A retracting member is preferably attached to the bottom of the handle and to a point on the body. The retracting member is preferably elastic. The retracting member is passed through an aperture on the body into the interior of the body and connected to at least one point inside the body 250. The retracting member may comprise two segments. The upper segment may be elastic and connect to the bottom portion of the handle. Lower segment may be inelastic or rigid and comprise two leg portions. Each of the leg portions is may preferably be attached at different points on the interior of the body.
