Description
FIELD OF THE INVENTION

The present invention generally relates to golf bags having a dual shoulder strap assembly wherein a first strap is fitted over one shoulder and a second strap is fitted over the other shoulder in order to desirably distribute the weight of the bag amongst both shoulders of a person carrying the bag.


BACKGROUND OF THE INVENTION

Both professional and recreational golfers use their golf bags for many different purposes today. The bags are normally designed to carry clubs and balls, and accessories such as head covers, towels, hats, umbrellas, and golf tees. Many golf courses require that golfers walk the entire course and carry their own bags. Thus, the golfer is constantly placing the bag over his/her shoulders, removing the bag from their shoulders, and placing the bag down or standing-up the bag using a support leg mechanism on the bag. The golfer is also constantly removing and placing different clubs in the bag depending upon the shot being made. Thus, the golf bag needs to be durable, relatively lightweight, and comfortable to carry.


Many golf bags have a two strap system so the golfer can bear the weight of the bag on both shoulders. The first strap fits over a person’s first shoulder and the second strap fits over the second shoulder. These dual straps tend to help improve the weight distribution of the bag and less weight stress is placed on each shoulder. The person carrying the bag tends to have better balance while walking with the bag because of this improved weight distribution.


However, two strap systems can have some drawbacks. For example, the golfer may easily place the first strap over the first shoulder, but then have difficulty finding and swinging the second strap over the second shoulder. The golfer may have to twist their back and arms at odd angles in order to swing the second shoulder strap over their second shoulder. This turning and twisting can lead to back and arm injuries. Additionally, once the two-strap system is mounted about the golfer’s shoulders, a golfer can have difficulty keeping the bag distributed across the golfer’s back sufficiently to maintain an even gate while progressing along the terrain of the course.


Thus, golf bag manufacturers continue to develop improved dual shoulder strap assemblies which better facilitate both mounting of the straps about the golfer’s shoulders as well as achieving and maintaining excellent distribution of the bag’s weight across the golfer’s back on the course. Such improved golf bags, if meanwhile durable, possessing high mechanical strength, and producible cost effectively within existing golf bag manufacturing processes, would be particularly useful and desirable. The current golf bag of the invention addresses and solves these needs.

DETAILED DESCRIPTION OF THE INVENTION

Advantageously, a golf bag of the invention includes a dual shoulder strap assembly which enables and facilitates mounting of both straps about the golfer’s shoulders as well as improves continued distribution of the bag’s weight across the golfer’s back on the course and is meanwhile durable, possesses high mechanical strength, and is producible cost effectively within existing golf bag manufacturing processes. Collectively, FIG. 1A, FIG. 1B, and FIG. 1C depict rear perspective views of a person carrying a golf bag incorporating a dual shoulder strap assembly according to three different constructions, and FIG. 1D depicts a frontal perspective views thereof. Golfer 1 carries golf bag 2 which comprises elongated tubular body 4 for holding golf clubs; as well as a dual shoulder strap assembly 6 that includes (i) a first strap 8, having a first end 10 and a second end 12; (ii) a second strap 14, having a first end 10 and a second end 12; and (iii) a bridge member 16 having a first end 18 and a second end 20.


Elongated tubular body 4 of golf bag 2 has a closed end 3 and an opposing open end 5, into which golf clubs 7 can be inserted into open end 5 of tubular body 4 (which has a cavity that is bordered by side walls (not shown)) of golf bag 2 such that, usually, golf club heads 9 with head covers 11 project from open end 5. The sidewall forming the cavity (not shown) within elongated tubular body 4 may include pockets and rings, and other compartments for golf balls, and accessories such as towels, hats, gloves, golf tees, beverages, and the like.


Elongated tubular body 4 can be made of any suitable textile material including leather, and woven/non-woven fabrics. Also, golf bag 2 may include a carrying handle and support leg assembly. The same or different fabric materials can be used to construct the elongated tubular body 4, such as lightweight, high-strength fabrics and/or plastics. For example, woven fabrics made of nylon, polypropylene, or polyester, can be used. Elastic webbing made of spandex or rubber fabric material also can be used. The webbing normally is relatively thin and has minimal or no padding. Plastic, metal, composite, or other suitable material may be used as well.


In turn, FIG. 2A, FIG. 2B, and FIG. 2C are enlarged/close-up views of the dual shoulder strap assemblies 6 depicted collectively in FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 1D respectively.


In each of these figures, bridge member 16 is disposed between and connecting the second ends 12 of first strap 8 and second strap 14 undetachably/unremovably/fixedly. Bridge member 16 is preferably formed from fabrics and/or compositions that are entirely or at least partially flexible, expandable, stretchable or otherwise pliable such as spandex or a rubber-containing fabric material. However, it is also envisioned that non-flexible fabrics and/or compositions may also be suitable materials for bridge member 16 such as an undetachable, non-removably attached plastic.


Meanwhile, elongated tubular body 4 of FIG. 1A, FIG. 1B, FIG. 1C and FIG. 1D is configured to be detachably adjoined/connected to first ends 10 and second ends 12 of each of first strap 8 and second strap 14 at connection mechanisms 13 and 15, respectively.


It is envisioned that first ends 10 and second ends 12 may be adjoined to elongated tubular body 4 either directly, or alternatively, indirectly by, for example, connecting straps 17 which are preferably undetachably/unremovably/fixedly attached to/adjoined with/to first ends 10 and second ends 12 yet detachably/removably attached/tethered to/adjoined with elongated tubular body 4 via attaching mechanisms 19 such as but not limited to sliders or other buckles, clips, clasps, hubs, pivots, eyehooks, loops, ties/knots, tri-glide clip, slide piece, or adjusting member that allows the shoulder strap to be adjusted lengthwise. Connecting straps 17 preferably have adjustable lengths.


In some embodiments, in lieu of attaching mechanisms 19, a bridge member such as bridge member 16 may be used to adjoin first ends 10 and second ends 12 to elongated tubular body 4 undetachably at both ends of each of straps 17. Any suitably shaped/constructed flexible or non-flexible or at least partially flexible bridge member may be used to adjoin first ends 10 and second ends 12 to elongated tubular body 4.


In one embodiment, as is represented in the cross-section of first strap 8 of FIG. 5, first strap 8 (as well as second strap 14, not shown) may be constructed so that sheath 22 is adjacent to support member 24 (illustrated in FIG. 3), which in turn is adjacent to gripping member 25 (having an underside with surface texturing 26 thereon in a predetermined pattern 27 such as also depicted in FIG. 4); wherein sheath 22 has a length Ls; support member 24 has a length Lsu; and gripping member 25 has a length Lg; wherein Lg<Lsu<Ls such that each strap (first strap 8/second strap 14) has a predetermined radius Rp. This construction can facilitate and improve how a strap 8 conforms to the wearer’s shoulder. In a specific embodiment, surface texturing 26 in a predetermined pattern 27 may be formed of a rubber-based material.


In another embodiment, each strap comprises a sheath that encloses a support member which has a contour that is configured to be enclosed by the sheath. In this embodiment, the support member(s) are preferably flexible, curved, lightweight and relatively flat when not flexed or otherwise bent.


In one embodiment, bridge member 16, first strap 8 and the second strap 14 are coupled horizontally within shoulder strap assembly 6 such as in FIG. 1A. In another embodiment, bridge member 16, first strap 8 and second strap 14 are coupled vertically within shoulder strap assembly 6 such as in FIG. 1B and FIG. 1C. Other constructions are likewise envisioned, for example, wherein bridge member 16, first strap 8 and second strap 14 are coupled diagonally within shoulder strap assembly 6.


As used herein, the phrase “coupled vertically” means that the intersection of the first end 18 (of bridge member 16) and the second end 12 (of first strap 8) is vertically aligned with the intersection of the second end 20 (of bridge member 16) and the second end 12 (of second strap 14). Meanwhile, as used herein, the phrase “coupled horizontally” means that the intersection of the first end 18 (of bridge member 16) and the second end 12 (of first strap 8) is horizontally aligned with the intersection of the second end 20 (of bridge member 16) and the second end 12 (of second strap 14).


In one embodiment, first strap 8 and second strap 14 are each flexibly adjoined to elongated tubular body 4; and first strap 8 is flexibly adjoined to second strap 14.


In one particular embodiment, shoulder strap assembly 6 is configured such that second strap 14 has a shape that is a reflection of the shape of first strap 8. In another particular embodiment, shoulder strap assembly 6 is configured such that second strap 14 has a shape that is a partial reflection of the shape of first strap 8.


In yet another embodiment, shoulder strap assembly 6 is configured such that second strap 14 has a shape that is a translation of the shape of first strap 8. In still another embodiment, shoulder strap assembly 6 is configured such that second strap 14 has a shape that is a partial translation of the shape of first strap 8.


In alternative embodiments, first strap 8 has a shape that differs partially or in its entirety from the shape of second strap 14.


In particular embodiments, first strap 8 is shorter than second strap 14, which can facilitate a golfer’s mounting and/or dismounting of the golf bag assembly by permitting one or more ends of first strap 8 to be released/disconnected from elongated body 4 before releasing one or more ends of second strap 14 so that the golf bag assembly can be slidably removed perhaps without even disconnecting second strap 14 from elongated body 4.


In one particular embodiment of a golf bag of the invention, shoulder strap assembly 6 comprises first strap 8 and second strap 14; wherein a first section of each strap is configured to be adjacent the wearer’s front or chest area; a second section of each strap is configured to be adjacent or rest upon a shoulder of the wearer; and a third section of each strap is configured to be adjacent wearer’s back; and wherein third section has a curve such that an upper portion of the third section extends vertically with respect to both the strap assembly and the wearer and a lower portion of the third section extends horizontally with respect to both the strap assembly and the wearer. It is envisioned that the lengths of each of the first, second and third sections can be pre-selected and coordinated considering torso measurement ranges for wearers or be customized according to match a particular wearer’s torso measurements.


As emphasized on first strap 8 in FIG. 2A, first strap 8 and second strap 14 may each have (i) a concave radius rcc extending from first end 10 to approximate a second end 12; and (ii) a convex radius rcv at second end 12; wherein rcc>rcn.


It is envisioned that any of the constructions/shaped/contours of first strap 8 and second strap 14 discussed herein may be reversed, which may be of particular use for example when considering whether a person is left-handed or right-handed.


Any portion of shoulder straps 8 and 14 can have a cushioned portion made of any suitable material including, but not limited to, foams, natural and synthetic leathers, natural and synthetic rubbers, woven and non-woven materials, and natural and synthetic fabrics. Foamed materials are particularly preferred for constructing the cushioned portions. These foamed materials have good stability and yet are also sufficiently flexible to make the cushioned portions comfortable when resting on the shoulders. These foamed materials can have a relatively soft durometer, for example, the hardness can be in the range of about 10 to about 80 Shore A. Another hardness scale (Asker®C) can be used to measure the indentation hardness of the foams, soft rubbers, elastomers or other materials, and the Asker C hardness is normally in the range of 25 to 75.


In general, foam compositions are made by forming gas bubbles in a polymer mixture using a foaming (blowing) agent. As the bubbles form, the mixture expands and forms a foam composition having either an open or closed cellular structure. Many foams contain both open and closed cells. Various thermoplastic and thermoset materials may be used in forming the foam compositions as discussed further below. In one preferred embodiment, a polyurethane foam composition is used to form the foam material. In another embodiment, ethylene vinyl acetate (EVA) foams are used. In a particularly preferred embodiment, a high-stretch, high-recovery foam material referred to as AriaPrene™, and available from Tiong Long Corp. can be used. This foam material is hypo-allergenic, lightweight, non-toxic, and decomposable.


Other thermoplastic elastomers that can be used in accordance with this invention include polyester-polyether block copolymers such as Hytrel® resins, available from DuPont. These block copolymers are available in different grades and contain hard (crystalline) segments of polybutylene terephthalate and soft (amorphous) segments based on long-chain polyether glycols. Polyether-amide block copolymers, which are commonly known as Pebax® resins, and are available from Arkema, Inc. (Columbs, France), also may be used. Other suitable thermoplastic polymers include, but are not limited to, polyurethanes, polyureas, silicones, ethylene acid copolymer ionomers, polyesters, polyolefins, polyamides, polyamide-ethers, polyamide-esters; fluoropolymers, polystyrenes, polyvinyl chlorides, polycarbonates, polyethers, and polyimides including homopolymers, copolymers, and modified polymers and blends thereof.


Natural and synthetic rubber materials also may be used. Suitable rubber materials include, but are not limited to, polybutadiene, polyisoprene, ethylene propylene rubber (“EPR”), ethylene-propylene-diene (“EPDM”) rubber, styrene-butadiene rubber, styrenic block copolymer rubbers (such as “SI”, “SIS”, “SB”, “SBS”, “SIBS”, “SEBS”, “SEPS” and the like, where “S” is styrene, “I” is isobutylene, “E” is ethylene, “P” is propylene, and “B” is butadiene), polyalkenamers such as, for example, polyoctenamer, butyl rubber, halobutyl rubber, polystyrene elastomers, polyethylene elastomers, polyurethane elastomers, polyurea elastomers, metallocene-catalyzed elastomers and plastomers, copolymers of isobutylene and p-alkylstyrene, halogenated copolymers of isobutylene and p-alkylstyrene, copolymers of butadiene with acrylonitrile, polychloroprene, alkyl acrylate rubber, chlorinated isoprene rubber, acrylonitrile chlorinated isoprene rubber, and blends of two or more thereof.


When numerical lower limits and numerical upper limits are set forth herein, it is contemplated that any combination of these values may be used. Other than in the operating examples, or unless otherwise expressly specified, all of the numerical ranges, amounts, values and percentages such as those for amounts of materials and others in the specification may be read as if prefaced by the word “about” even though the term “about” may not expressly appear with the value, amount or range. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention.
