1. Field of the Invention.

[0006] ^r Fh is invention relates generally to a triune quick release assembly and connection golf club system, and more particularly, a quick release golf club with an improved assembly, disassembly and connection between the club shaft to allow the golfer to effortlessly change the club grip and/or club head.

2. Description of the Related Art.

[0007] Golf is a popular game played worldwide by professionals and amateurs. It requires a great deal of concentration and precision. Since its inception, golf equipment manufacturing has evolved into a highly technical field. The two main pieces of equipment needed are a golf club and a golf ball. The golf club is probably the most important piece of equipment needed to master the game. A club consists of three components; the head, the shaft, and the grip. The head of the club, also called the "wood" or "iron" is located at the bottom of the shaft and the grip is located at the top. Today, most heads are made using advanced materials such as titanium, graphite, and zirconia. With so many technological capabilities, there are a number golf component parts available today. There are also multiple club variations such as in the loft angle, lie angle, offset features, and weighting.

[0008] Club heads can be combined with different shafts based on flex or kick points for example. Considering the available variations in shafts and club heads, there are literally hundreds of different club head/shaft combinations available to the golfer. A club fitter can assist the golfer with the best comhination for his swing characteristics and needs. Traditional golf heads were permanently mounted to shafts using cements or adhesives. Therefore, to enable a golfer to test a variety of head/shaft combinations, the golfer had to carry several combinations of clubs, which are heavy and take up a lot of space.

[0009] The rules of golf require players to utilize fourteen (14) clubs during the game. However, carrying this number of standard clubs can be cumbersome. Customization of golf clubs will always be a compelling need for a golfer regardless of his skill level. Golfers need to make a quick decision as to what type of iron they are going to use for the next shot. There is a definite need for a golfer to be able to use the shaft he is most comfortable with and quickly change the iron/wood or grip based on his preference, in addition, golfers have a limited time to make the next shot and often times the pins and release tools of prior golf clubs are difficult to align and lock thereby causing delay. Some release tools require several minutes to align, insert, and lock which may cause frustration for the golfer, thereby causing him to lose his concentration for the next shot.

[0010] With the game of golf becoming more and more popular each year, golfers of any skill level will demand a customized full set of clubs that are easily transportable, yet offer the same functionality as a weighty and cumbersome traditional 14-bag set. Standard clubs, however, cannot fit in the overhead compartments on airplanes. Therefore, the traveling golfer would benefit from a compact carrying case which holds a standard shaft (driver), a standard putter, two grips: one for the driver and one for the putter; and preference as to the number of woods, irons, and wedges to form a complete set.

[001 1] Notwithstanding, in an already crowded field of golf clubs with quick release heads and grips, there exists a continuing need for a new and improved golf club assembly and disassembly to easily and quickly change the desired head and grip, while offering travel portability.

[0012] it is therefore desirable to provide a quick release golf club with an improved assembly, disassembly and connection with the club shaft to allow the golfer to effortlessly change the club grip and/or club head.

[0013] It is further desirable to provide a triune quick release assembly and connection golf club system that does not utilize pins, screws or release tools like the latest clubs on the market, because such adaptations are not necessarily as "quick" as claimed.

[0014] It is still further desirable to provide a triune quick release assembly and connection golf club system that is invaluable to the business traveler who desires to use personal yet portable elubs when he travels, because the weight and bulk of common design standard golf bags along with a full set of clubs are extremely cumbersome when navigating through airports.

[0015] Other advantages and features of the invention will be apparent from the following description and from the claims.

[0045] In general, the invention is directed to a triune quick release assembly and connection golf club system 10 having an improved assembly, disassembly and connection between a club shaft 12 and a club grip 14 and/or a club head 16 that allows a golfer to quickly and easily change the club grip 14 and/or the club head 16. The triune quick release assembly and connection golf club system 10 is illustrated throughout the figures with the club head 16 as an iron, but is not so limited, and can also be constructed with a wood club head or with a putter club head. The triune quick release assembly and connection golf club system 10 includes a quick, release connection 18 between the club shaft 12 and the club grip 14, and also includes a quick release connection 20 between the club shaft 12 and the c!ub head 16.

[0046] Referring now to the figures of the drawings, wherein like numerals of reference designate like elements throughout the several views and initially to Figures 1 through 5, the quick release connection 18 between the club shaft 12 and the club grip 14 includes a shank 22 having a stem 24 protruding from a lower terminal end 26 of the club grip 14. The shank 22 includes an cylindrical insert 25 integrally fabricated within the lower terminal end 26 of the club grip 14, and the lower terminal end 26 of the club grip 14 includes an annular stop shoulder 28 intermediate of the stem 24 and the cylindrical insert 25. As exemplified in Figures 2 and 3, the stem 24 is a hexagonal stem, but is not so limited, and may be configured as any polygonal shape, such as a convex polygon, e.g., triangular, square, pentagonal, heptagonal, octagonal, p- gonal. or a star polygon, e.g., pentagram, heptagram, octagram, enneagrams, -agrams. A cylindrical fastener 30 having a partial internally threaded bore 32 is received about and slidably engaged with the lower terminal end 26 of the club grip 14. Similar to the biased retainer sleeve 140 illustrated in Figures 16 through 19, the cylindrical fastener 30 may be biased toward the quick release connection 18 using a biasing spring or other biasing mechanism 148 that is retained within the cylindrical fastener 30.

[0047] The quick release connection 18 between the club shaft 12 and the club grip 14 also includes a chuck 34 having an externally threaded portion 36 protruding from an upper terminal end 38 of the club shaft 52. The chuck 34 includes a cylindrical insert 40 integrally- fabricated within the upper terminal end 38 of the club shaft 12, and the lower terminal end 26 of the club grip 34 includes an annular shop shoulder 42. A retaining element 44 is integrally fabricated within an internal opening 46 of the externally threaded end 36 of the chuck 34, and as exemplified in Figures 2 and 3, the retaining element 44 has an interna! bore 48 with a polygonal shape matching that of the stem 24 of the shank 22.

[0048] As illustrated in Figure 3, in order to connect the club grip 14 to the club shaft 12 using the quick release connection 18, the protruding stem 24 of the shank 22 is inserted into the internal bore 48 of the chuck 34. The fastener 30 is biased and slid down the terminal end 26 of the grip 34, and the golfer may hand tighten the fastener 30 to the externally threaded end 36 of the chuck 34. The quick release connection 18 between the annular stop shoulder 28 on the lower terminal end 26 of the club grip 34, the fastener 30 and the externally threaded end 36 of the chuck 34 prevent separation of the club grip 14 with respect to the club shaft 12, while the mating polygonai configurations of the stem 24 and the interaai bore 48 of the chuck 34 prevent rotation and/or slippage of the club grip 14 with respect to the club shaft 12,

[0049] The quick release connection 20 between a lower terminal end 50 of the club shaft 12 and a hose! 52 of the club head 16 is exemplified in Figures 4 and 5. A chuck 54 is integrally fabricated within the lower terminal end 50 of the club shaft 12, and the chuck 54 includes an internal bore 56. The lower terminal end 50 of the club shaft 12 includes an annular stop shoulder 58, and a cylindrical fastener 60 having a partial internally threaded bore 62 is received about and slidabl engaged with the lower terminal end 50 of the club shaft 12. Similar to the embodiment illustrated in Figures 16 through 19, the cyiindricai fastener 60 may be biased toward the quick release connection 20 using a biasing spring or other biasing mechanism 148 that is retained within the cylindrical fastener 60. The hose! 52 is prefabricated with the club head 16 and with an integral shank 64 to form unitary club head, without any attachment or other fastener apertures therein. The shank 64 of the club head 16 includes an externally threaded portion 66. an annular stop shoulder 68 and a stem 70 protruding from the annular stop shoulder 68. As illustrated in Figures 4 and 5, the interna! bore 56 of the chuck 54 and the protruding stem 70 of the club head 16 are hexagonal, but the quick release connection 20 is not so limited, and like the quick release connection 18 discussed above, may be configured as any polygonal shape, such as a convex polygon, e.g., triangular, square, pentagonal, heptagonal, octagonal, p- gonal, or a star polygon, e.g., pentagram, heptagram, octagram, enneagrams, ; agrams.

[0050] As illustrated in Figure 5, in order to connect the club shaft 32 to the club head 16 using the quick release connection 20, the internal bore 56 of the chuck 54 seated about the protruding stem 70 of the unitary club head 16. Similarly to the quick release connection 18, the fastener 60 is biased and slid down the terminal end 50 of the shaft 12, and the fastener 60 is secured to the externally threaded portion 66 of the shank 64. The quick release connection 20 between the annular stop shoulder 58 on the lower terminal end 52 of the club shaft 12, the fastener 60 and the externally threaded portion 66 of the of the shank 64 prevent separation of the unitary club head 16 with respect to the club shaft 12, while the mating polygonal configurations of the stem 70 and the internal bore 56 of the chuck 54 prevent rotation and/or slippage of the club head 16 with respect to the club shaft 12.

[00 1 ] Turning now to Figures 6 through 1 1 illustrating another example of the inventive triune quick release assembly and connection golf club system 10 having an improved assembly, disassembly and connection between the club shaft 12 and the club grip 34 and/or the club head 16. The quick release connection 18 between the club shaft 12 and the club grip 34 includes the shank 22 having the stem 24 protruding from the lower terminal end 26 of the club grip 1 . The shank 22 includes the cylindrical insert 25 integrally fabricated within the lower terminal end 26 of the club grip 14. The stem 24 illustrated in Figures 7 through 9 includes longitudinal axial channels 72A and 72B, each respectively terminating with lateral axial channels 74A and 74B,

[0052] The quick release connection 18 between the club shaft 12 and the club grip 14 also includes opposed detents 76A and 768 integrally fabricated and protruding within the upper terminal end 38 of the club shaft 12. The upper terminal end 38 of the club shaft 12 also includes a biasing mechanism 78 comprised of a spring or other biasing device 80 sandwiched between an upper slidable disc 82 and a lower fixed disc 84.

[0053] As illustrated in Figure 9, in order to connect the club shaft 12 to the club grip 14 using the quick release connection 1 8, the golfer aligns the longitudinal axial channels 72A and 72B of the stem 24 with the detents 76 A and 76B within the upper terminal end 38 of the club shaft 12. The stem 24 of the shank 22 is then inserted into the upper terminal end 38 of the club shaft 12 until a terminal end of the stem 24 engages the upper slidab!e disc 82 of the biasing mechanism 78. The golfer continues this insertion until the spring 80 is compressed against the fixed disc 84, and then rotates the club shaft 12 and/or the club grip 14 in order to slide the detents 76A and 76B from the longitudinal axial channels 72A and 72B into the lateral axial channels 74A and 74B.

[0054] The quick release connection 20 between the lower terminal end 50 of the club shaft 12 and the hosel 52 of the club head 16 is exemplified in Figures 10 and 1 1. The hosel 52 is prefabricated with the club head 16 to form the integral shank 64 as a unitary piece. The shank 64 of the club head 1 includes the annular stop shoulder 68 and the stem 70 protruding from the annular stop shoulder 68. The stem 70 of the unitary club head 16 includes longitudinal axial channels 86A and 86B, each respectively terminating with lateral axial channels 88A and 88B. Similar to the upper terminal end 38 of the club shaft 12, opposed detents 90A and 90B integrally are fabricated and protrude within the lower terminal end 50 of the club shaft 12. In addition, a biasing mechanism 92 is secured within the lower terminal end 50, and includes spring or other biasing device 94 sandwiched between a lower slidable disc 96 and an upper fixed disc 98.

[0055] In order to connect the club shaft 12 to the club head 16 using the quick release connection 20, the golfer aligns the longitudinal axial channels 86A and 86B of the stem 70 with the detents 90A and 90B within the lower terminal end 50 of the club shaft 12 and then inserted into the lower terminal end 50 until a terminal end of the stem 70 engages the lower slidable disc 96 of the biasing mechanism 92. The golfer continues this insertio until the spring 94 is compressed against the fixed disc 98 and the lower terminal end 50 of the club shaft 12 engages the stop shoulder 68 of the unitary club head 16. The golfer then rotates the club shaft 12 and/or the club head 16 in order to slide the detents 90 A and 90B from the longitudinal axial channels 86A and 86B into the lateral axial channels 88A and 88B,

[0056] Referring now to Figures 12 through 15, the quick release connection 18 between the club shaft 12 and the club grip 14 includes the shank 22 having the stem 24 protruding from the lower terminal end 26 of the club grip 14. The shank 22 includes the cylindrical insert 25 integrally fabricated within the lower terminal end 26 of the club grip 14. The stem 24 illustrated in Figures 13 and 14 includes longitudinal helical channels 100A and lOOB, each respectively terminating with the lateral axial channels 74A and 74B. The quick release connection 18 also includes the opposed detents 76A and 76B integrally fabricated and protruding within the upper terminal end 38 of the club shaft 12. The upper terminal end 38 of the club shaft 12 also includes the biasing mechanism 78 comprised of the spring or other biasing device 80 sandwiched between the upper siidable disc 82 and the lower fixed disc 84. As also shown in Figures 13 and 14, the quick release connection 18 includes a secondary fastener 102 secured to the lower terminal end 26 of the club grip 14. As exemplified, the secondary fastener 102 is a thumb-actuated latch 104 downwardly biased by a spring 106 mounted within the lower terminal end 26 of the club grip 14. The latch 104 also includes a protruding bayonet 108 that is received within a bayonet receptacle 1 10 in the upper terminal end 38 of the club shaft 12.

[0057] In order to connect the club shaft 12 to the club grip 14 using the quick release connection 18 shown in Figures 13 and 14, the golfer aligns the longitudinal helical channels 100A and 100B of the stem 24 with the detents 76A and 76B within the upper terminal end 38 of the club shaft 12. The stem 24 of the shank 22 is then inserted into the upper terminal end 38 of the club shaft 12, and the latch 104 of the secondary fastener 102 is retracted. The club shaft 12 and/or the club grip 14 are rotated until a terminal end of the stem 24 engages the upper siidable disc 82 of the biasing mechanism 78. The golfer continues this rotational insertion until, the spring 80 is compressed against the fixed disc 84, and then rotates the club shaft 12 and/or the club grip 14 in order to slide the detents 76A and 76B from the longitudinal helical channels 500A and 1O0B into the lateral axial channels 74A and 74B. The golfer then disengages the latch 104 and the bayonet protrusion 108 of the secondary fastener 102 slides within the bayonet receptacle within the upper terminal end 38 of the shaft 12. The detents 76A and 76 B are forced by the biasing mechanism 78 to engage with the lateral axial channels 74A and 74B of the quick release connection 18 in order prevent separation of the club grip 14 with respect to the club shaft 12, while the secondary fastener 102 further prevents rotation and/or slippage of the club grip 14 with respect to the club shaft 12.

[0058] The quick release connection 20 between the lower terminal end 50 of the club shaft 32 and the hose! 52 of the club head 16 is exemplified in Figures 15. The lower terminal end 50 of the club shaft 12. includes the annular stop shoulder 58, and the cylindrical fastener 60 having the partial internally threaded bore 62 is received about and slidably engaged with the lower terminal end 50 of the club shaft 12. The cylindrical fastener 60 may be biased toward the quick release connection 20 using a biasing spring or other biasing mechanism 148 that is retained within the cylindrical fastener 60. The hosel 52 is prefabricated with the club head 16 to form the integral shank 64 as a unitary piece. The shank 64 of the club head 16 includes the externally threaded portion 66, the annular stop shoulder 68 and the stem 70 protruding from the annular stop shoulder 68. The stem 70 of the unitary club head 16 includes longitudinal axial channels 86Λ and 86B or longitudinal helical channels 100A and 100B. each respectively terminating with lateral axial channels 88A and 88B. The opposed detents 90A and 90B integrally are fabricated and protrude within the lower terminal end 50 of the club shaft 12. In addition, the biasing mechanism 92 is secured within the lower terminal end 50, and includes the spring or other biasing device 94 sandwiched between the lower slidable disc 96 and the upper fixed disc 98.

[0059] In order to connect the club shaft 12 to the club head 16 using the quick release connection 20 illustrated in Figure 15, the golfer aligns the longitudinal axial channels 86A and 86B or longitudinal helical channels 100A and 100B of the stem 70 with the detents 90A and 9GB within the lower terminal end 50 of the club shaft 12 and then inserts the stem 70 into the lower terminal end 50 until a terminal end of the stem 70 engages the lower slidable disc 96 of the biasing mechanism 92. The golfer continues this insertion until the spring 94 is compressed against the fixed disc 98 and the lower terminal end 50 of the club shaft 12 engages the stop shoulder 68 of the unitary club head 16. The golfer then rotates the club shaft 12 and/or the club head 16 in order to slide the detents 90A and 90B from the longitudinal axial channels 86A and 86B or longitudinal helical channels 100A and 100B into the lateral axial channels 88A and 8SB. The biased fastener 60 moves down the terminal end 50 of the shaft 12, and the fastener 60 is attached to the externally threaded portion 66 of the shank 64.

[0Ό60] Turning now to Figures 16 through 39, the triune quick release assembly and connection golf club system 10 is illustrated as a suitable quick release connection 18 between the club shaft 12 and the club grip 14 or quick release connection 20 between the club shaft 12 and the club head 16. The stem 24 protrudes from the lower terminal end 26 of the c!ub grip 14, the upper terminal end 38 of the club shaft 12, and/or from the hosel 52 of the club head 16. As exemplified in Figures 16 through 19, the stem 24 is a hexagonal stem, but is not so limited, and may be configured as any polygonal shape, such as a convex polygon, e.g., triangular, square, pentagonal, heptagonal, octagonal, / gonal. or a star polygon, e.g., pentagram, heptagram. octagram, enneagrams, />-agrams. The cylindrical fastener 30 has the partial internally threaded bore 32 and is received about and slidab!y engaged with the stem 24. The stem 24 terminates in an elongate plug body i 12 having an annular channel 1 34 and an annular stop shoulder 1 16. As illustrated in Figure 17, but not by way of limitation, the plug body 1 12 is a generally cylindrical body having opposed planar side faces 1 18 and opposed arcuate upper and lower faces 120. The channel 1 14 intersects both the side faces 1 18 and the upper and lower faces 120 of the plug body 1 1 .

[0061 ] A plug retaining chuck 122 i integrally fabricated to the lower terminal end 26 of the club grip 14, the upper terminal end 38 of the club shaft 12, and/or the lower terminal end 50 of the club shaft 12. The plug retaining chuck 122 is configured to receive the elongate plug body 1 32 within an axial bore 124, which as illustrated, but not by way of limitation, also includes opposed planar side faces 326 and opposed arcuate upper and lower faces 128. The plug retaining chuck 122 includes an annular stop shoulder 330 positioned adjacent to the lower terminal end 26 of the c!ub grip 14, the upper terminal end 38 of the club shaft 52, and/or the lower terminal end 50 of the club shaft 12. The plug retaining chuck 122 also includes a terminal externally threaded portion 132 and a plurality of bearing bores 134. The plug retaining chuck 122 also includes an annular retainer groove 136 for receipt of a retaining ring 338.

[0062] A biased retainer sleeve 140 is slidably engaged about the plug retaining element 322. The biased retainer sleeve 140 includes an axial bore 142 having radially aligned bearing retainers 144 for receipt of bail thrust bearings 150, which reduce friction and maximize torque. The biased retainer sleeve 140 also includes a biasing spring retaining portion 345 that terminates with an annular spring stop shoulder 146. A biasing spring or other biasing mechanism 148 is retained within the biasing spring retaining portion 145, and the biasing spring 348 is positioned intermediate of the annular spring stop shoulder 146 of the biased retainer sleeve 140 and the annular stop shoulder 130 of the plug retaining element 122.

[0063] The triune quick release assembly and connection golf club system 10 constructed as exemplified in Figures 16 through 19 enables the golfer to quickly pull the biased retainer sleeve 140 to release the stem of the club head 16 or the ciub grip 14. To connect the club head 16 or the club grip 14 to the club shaft 12, the golfer merely pulls back the biased retainer sleeve 140, inserts the elongate plug body 3 12 into the plug retaining element 120, and releases the biased retainer sleeve 140. The biasing spring 140 pushes the biased retainer sleeve 140 forward, and the ball thrust bearings 150 move from the bearing retainers 144 into the annular channel 1 14 of the elongate plug body 1 12 at the terminal end of the stem 24. The golfer may then further lock the desired component in place using the retaining ring 138 and/or securing the fastener 30 to the plug retaining element 122.

[0064] The triune quick release assembly and connection golf club system 10 provides an improved interchangeable club head 16 with the quick release connection 20 comprised of a prefabricated mold of the shank 22 that allows a simple downward push, twist and lock inside the chuck 64 at the end of the club shaft 12 and/or the ciub grip 14. Likewise, the interchangeable club grip 14 may include the prefabricated mold of the shank 22 at the lower terminal end 26 to receive the club shaft 12. In addition, the club shaft 12 may include a prefabricated mold of the shank 22 at the upper terminal end 38 of the club shaft 12 and the lower terminal end 50 of the club shaft 12 to receive the club grip 14 and club head 14, respectively. Therefore, the triune quick release assembly and connection golf club system 10 can be constructed using a prefabricated molded shank 22 for the club head 16, the club grip 14, and/or a prefabricated moided shank 22 for the lower terminal end 26 and the upper terminal end 38 of the c!ub shaft 12. Regardless of the manufacturing configuration, the triune quick release assembly and connection golf club system 10 includes at least two (2) quick release connections: the quick release connection 18 between the ciub shaft 12 and the club grip 14, and the quick release connection between the ciub shaft 12 and the club head 16.

[0065] A further aspect of the triune quick release assembly and connection golf club system 10 relates to marketing, selling, manufacturing, or utilizing one or more components of the golf club system 10 as a kit including a travel bag.
