DETAILED DESCRIPTION OF THE INVENTION

(21) 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.

(22) 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.

(23) 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 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.

(24) 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, and FIGS. 1C, and 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.

(25) 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.

(26) 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/ajoined with/to first ends 10 and second ends 12 yet detachably/removably attached/tethered to/ajoined 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.

(27) 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.

(28) 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, 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 L.sub.s; support member 24 has a length L.sub.su; and gripping member 25 has a length L.sub.g; wherein L.sub.g<L.sub.su<L.sub.s such that each strap (first strap 8/second strap 14) has a predetermined radius R.sub.p. 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.

(29) 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.

(30) 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.

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

(32) 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.

(33) 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.

(34) 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.

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

(36) 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.

(37) 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.

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

(39) 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.

(40) 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-wovens, 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.

(41) 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.

(42) 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.

(43) 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. All patents, publications, test procedures, and other references cited herein, including priority documents, are fully incorporated by reference to the extent such disclosure is not inconsistent with this invention and for all jurisdictions in which such incorporation is permitted. It is understood that the compositions, golf ball components, and finished golf balls described and illustrated herein represent only some embodiments of the invention. It is appreciated by those skilled in the art that various changes and additions can be made to compositions and products without departing from the spirit and scope of this invention. It is intended that all such embodiments be covered by the appended claims.
