Definitions
- the present invention relates, in general, to equipment for playing the game of billiards and more specifically relates to billiard cues and billiard cue assemblies.
- a billiard cue is used to strike a ball.
- a billiard cue is a tapered rod having a tip at one end for striking a ball, and a butt end at the opposite end.
- the half of the tapered rod adjoining the butt end is typically called the butt, while the half of the tapered rod adjoining the tip is typically called the shaft.
- the shaft and butt portion are detachable.
- the billiard cue is typically held at a haft portion close to the butt end.
- the taper provided to the rod is typically a positive taper. That is, the thickness of the billiard cue will gradually diminish moving away from the butt end towards the tip. At some segments of the rod, the length may remain constant. For example, it is common for billiard cues to have a positive taper along the butt and at that portion of the shaft that is closer to the butt, and to have a portion of the shaft closer to the tip that is of substantially constant thickness.
- a user will typically hold the cue along a haft portion adjoining the butt end of the cue, and will provide a bridge for a shaft of the cue using the other hand.
- the user then moves the billiard cue in a direction substantially parallel to the longitudinal dimension of the cue, to strike the cue ball into the other balls.
- the user sights along the cue to the bridge hand to aim the shot.
- a cue that impedes the gripping hand from moving forward on the haft portion of the cue, and thus permits a user to hold the cue with a lighter touch is desirable, as is a cue that helps a user to consistently place the gripping hand at the same point along the length of the cue.

Abstract
A billiard cue is provided comprising an elongate rod having a ball striking tip at a first end thereof, and a haft portion extending along one-third of the length of the rod from the second end thereof. The haft portion is wider than the tip and has a first tapered section narrowing toward the second end. In use in striking a ball, the cue may be held at a position along the haft portion closer to the second end than an associated widest part of the first tapered section.
Description
- The present invention relates, in general, to equipment for playing the game of billiards and more specifically relates to billiard cues and billiard cue assemblies.
- In billiards (which, as used below, is intended to refer to all billiards games, including snooker, pool and carom), a billiard cue is used to strike a ball. A billiard cue is a tapered rod having a tip at one end for striking a ball, and a butt end at the opposite end. The half of the tapered rod adjoining the butt end is typically called the butt, while the half of the tapered rod adjoining the tip is typically called the shaft. Often, the shaft and butt portion are detachable. In use in striking a ball, the billiard cue is typically held at a haft portion close to the butt end.
- The taper provided to the rod is typically a positive taper. That is, the thickness of the billiard cue will gradually diminish moving away from the butt end towards the tip. At some segments of the rod, the length may remain constant. For example, it is common for billiard cues to have a positive taper along the butt and at that portion of the shaft that is closer to the butt, and to have a portion of the shaft closer to the tip that is of substantially constant thickness.
- To use the billiard cue, a user will typically hold the cue along a haft portion adjoining the butt end of the cue, and will provide a bridge for a shaft of the cue using the other hand. The user then moves the billiard cue in a direction substantially parallel to the longitudinal dimension of the cue, to strike the cue ball into the other balls. The user sights along the cue to the bridge hand to aim the shot.
- When the cue strikes the cue ball, there will be some jarring of the cue as momentum is transferred to the cue ball. This jarring is increased for break shots or for shots that are delivered off the side of the billiard table, which must be delivered with great force, but also with great accuracy. This jarring may cause the user's hand to slip forwardly on the haft portion, possibly causing the shot to go astray.
- It is also important that a user be able to consistently place their hand on the same place on the cue, as placement of the hand on different positions on the cue will add an additional variable that may affect any shot that is made. Specifically, the position of the hand on the cue will affect the elbow and arm position. In billiards, precision and accuracy are absolutely crucial. Thus, it is important, that a player consistently adopt a consistent position in order to provide the muscle memory required for this precision and accuracy. Professionals can often tell where their hand is on a cue. However, less experienced players will often vary their hand position without realizing it.
- Accordingly, a cue that impedes the gripping hand from moving forward on the haft portion of the cue, and thus permits a user to hold the cue with a lighter touch, is desirable, as is a cue that helps a user to consistently place the gripping hand at the same point along the length of the cue.
- An object of an aspect of the present invention is to provide an improved billiard cue that addresses these points, obviating or mitigating the problems of known cues.
- In accordance with an aspect of the present invention, there is provided a billiard cue. The billiard cue comprises an elongate rod having a ball striking tip at a first end thereof, and a haft portion extending along one-third of the length of the rod from the second end thereof. The haft portion is wider than the tip and has a first tapered section narrowing toward the second end. In use in striking a ball, the cue may be held at a position along the haft portion closer to the second end than an associated widest part of the first tapered section.
- In accordance with a second aspect of the present invention, there is provided a butt of a billiard cue assembly for attachment to a shaft of the billiard cue assembly to form a billiard cue. The shaft has a ball striking tip at one end thereof and an attachment means at the opposite end thereof. The butt comprises a mating attachment means at one end thereof for attachment to the attachment means of the shaft to attach the shaft and the butt together; a second end at the other end thereof; and, a haft portion extending along two-thirds of the length of the butt from the second end thereof. The haft portion is wider than the tip and has a first tapered section narrowing toward the second end. In use in striking a ball, the cue may be held at a position along the haft portion closer to the second end than an associated widest part of the first tapered section.
- In accordance with a third aspect of the present invention, there is provided grip for attachment to a butt of a billiard cue. The billiard cue has a ball striking tip at a first end thereof, and a haft portion extending along one-third of the length of the cue from a second end thereof. The grip is adapted for mounting on the cue and comprises an inner surface adapted to retain the grip on the haft portion when the grip is mounted on the cue; and, an outer surface providing a first tapered section narrowing toward the second end of the cue when the grip is mounted thereon. When the grip is mounted on such a cue, the cue may, in use in striking a ball, be held by the grip at a position on the grip closer to the second end than an associated widest part of the first tapered section of the grip.

billiard cue 30 is formed by ashaft 38 and abutt 36. As is conventional, thebutt 36 includes a threadedprotrusion 40 that is dimensioned to fit within a mating threaded aperture (not shown) of theshaft 38. Theshaft 38 has atip 32 for striking a cue ball at one end and the threaded aperture at anopposite end 42. Thebutt 36 has abutt end 34 at one end and the threadedprotrusion 40 at the other. When thebutt 36 andshaft 38 are joined together, abilliard cue 30 similar to that shown in FIG. 1A is formed. A portion A that includes thebutt end 34 of thebutt 36 of FIG. 1B embodies the invention. - Referring to FIGS. 2 and 3, the portion A of the
billiard cue 30 of FIG. 1A and the portion A of thebutt 36 of FIG. 1B is illustrated in a side view and an oblique view respectively. - Referring to FIG. 4, the portion A of the
butt 36 of FIGS. 1A and 1B is illustrated in an enlarged side view. From the side view, it is apparent that the diameter of thebutt 36 is less at section C-C, than it is at either section B-B or section D-D on either side of section C-C. That is, there is a positive taper from section B-B to section C-C, as the thickness of thebutt 36 diminishes moving forward from thebutt end 34, and there is a reverse taper from section C-C to section D-D as the thickness of thebutt 36 increases moving away from thebutt end 34. From section D-D to section E-E, there is a positive taper as the thickness of thebutt 36 diminishes moving forward from thebutt end 34. From section A-A to section B-B, there is a negative taper as the thickness of the butt increases moving forward from thebutt end 34. This geometry is also apparent from FIGS. 5 to 9 that illustrate the sections marked in FIG. 4. - Referring to FIG. 5, the butt of FIG. 4 is illustrated in a sectional view along the line A-A of FIG. 4. A diameter of the
butt 36 at section A-A is marked D1 on FIG. 5. Referring to FIG. 6, thebutt 36 of FIG. 4 is shown in a sectional view taken along the line B-B of FIG. 4. The diameter of thebutt 36 at section B-B is marked D2 on FIG. 6. Referring to FIG. 7, thebutt 36 of FIG. 4 is shown in a sectional view along the line C-C of FIG. 4. The diameter of thebutt 36 at this point is marked D3. Referring to FIG. 8, thebutt 36 is shown in a sectional view along the line D-D of FIG. 4. At line D-D, thebutt 36 has a diameter D4. Referring to FIG. 9, thebutt 36 of thebilliard cue 30 is shown in a sectional view along the line E-E of FIG. 4. The diameter of thebutt 36 at line E-E of FIG. 4 is designated D5. - According to the embodiment of the invention shown in FIGS. 1 through 9, the diameter of the
butt 36 gradually increases from diameter D1 at section A-A adjoining thebutt end 34 to diameter D2 at section B-B. Moving from section B-B away from thebutt end 34, the diameter of thebutt 36 gradually diminishes to the smaller diameter D3 at section C-C. Continuing in the same direction, the diameter of thebutt 36 then gradually increases to the diameter D4 at section D-D, and then again gradually diminishes to the smaller diameter D5 at section E-E. Thus, there is a reverse taper from larger diameter D2 at section B-B to smaller diameter D1 at section A-A, a positive taper from smaller diameter D3 at section C-C to larger diameter D2 at section B-B, a reverse taper from larger diameter D4 at section D-D to a smaller diameter D3 at section C-C, and a positive taper from smaller diameter D5 at section E-E to larger diameter D4 at section D-D. - Preferably, as shown in FIG. 4, the slope of the
butt 36 resulting from its changing thickness changes without any discontinuity. Thus, on each side of the sections D-D, C-C, and B-B the slope of thebutt 36 gradually becomes zero such that there is no abrupt discontinuous change in the slope of the butt surface. Instead, the slope of thebutt 36 between sections D-D and C-C smoothly merges into the slope of thebutt 36 between sections C-C and B-B. Preferably, as shown in FIG. 4, there is an elongated constant diameter section around section C-C to facilitate gripping. - In using a
billiard cue 30 having thebutt 36 of FIG. 4, a user would hold thebutt 36 at a haft portion between sections B-B and D-D. The thickness of thebutt 36 between the sections C-C and D-D increases towards thetip 32, such that the resulting slope will tend to resist the user's hand slipping forward on thebutt 36. This slope will also serve as a non-visual aid to the user placing his or her hand, as the change in thickness of thebutt 36 will provide a sensation to the user that is directly proportional to the distance of the hand along thebutt 36. At the same time, however, due to the smooth surface provided, the slope of thebutt 36 will not adversely affect the aesthetic appearance of thebutt 36, nor will it provide any rough surfaces that may catch on obstructions to ruin a shot. - Referring to FIG. 10A, a
billiard cue 60 in accordance with a third preferred embodiment of the invention is illustrated in a side view. The billiard cue is formed by a tapered rod having atip 62 for striking a cue ball at one end and abutt end 64 opposite thetip 62. The billiard cue includes abutt 66 and ashaft 68. A portion A that includes thebutt end 64 of thebilliard cue 60 embodies the invention. - Referring to FIG. 10B, a
billiard cue assembly 61 in accordance with a fourth preferred embodiment of the invention is illustrated in a side view. In the description that follows, the same reference numerals are used to designate analogous elements of thebilliard cue 60 of FIG. 10A and thebilliard cue assembly 61 of FIG. 10B. Abilliard cue 60 is formed from theassembly 61 by joining ashaft 68 and abutt 66. Theshaft 68 has atip 62 for striking a cue ball at one end and a threaded aperture (not shown) at anopposite end 72. Thebutt 66 has abutt end 64 atone end and a threadedprotrusion 70 at the other. As is conventional, the threadedprotrusion 70 is dimensioned to fit within the mating threaded aperture of theshaft 68 to attach thebutt 66 andshaft 68 together. When thebutt 66 andshaft 68 are joined together, a billiard cue similar to that shown in FIG. 1 OA is formed. A portion A that includes thebutt end 64 of thebutt 66 of FIG. 10B embodies the invention. - Referring to FIGS. 11 and 12, the portion A of the
billiard cue 60 of FIG. 10A and the portion A of thebutt 66 of FIG. 10B is illustrated in a side view and an enlarged side view respectively. Referring to FIG. 13, thebutt 66 of FIG. 12 is illustrated in a sectional view along the line A-A of FIG. 12. A diameter of thebutt 66 at section A-A is marked DA on FIG. 13. Referring to FIG. 14, thebutt 66 of FIG. 12 is shown in a sectional view taken along the line B-B of FIG. 12. The diameter of thebutt 66 at section B-B is marked DB on FIG. 14. Referring to FIG. 15, thebutt 66 of FIG. 12 is shown in a sectional view along the line C-C of FIG. 12. The diameter of thebutt 66 at this point is marked DC. Referring to FIG. 16, thebutt 66 is shown in a sectional view along the line D-D of FIG. 12. At line D-D, thebutt 66 has a diameter DD. Referring to FIG. 17, thebutt 66 of FIG. 12 is shown in a sectional view along the line E-E of FIG. 12. The diameter of thebutt 66 at line E-E of FIG. 12 is designated DE. Referring to FIG. 18, thebutt 66 of FIG. 12 is shown in a sectional view along the line F-F of FIG. 12. The diameter of thebutt 66 at line F-F of FIG. 12 is designated DF. Referring to FIG. 19, thebutt 66 of FIG. 12 is shown in a sectional view along the line G-G of FIG. 12. The diameter of thebutt 66 at line G-G of FIG. 12 is designated DG. Referring to FIG. 20, thebutt 66 of FIG. 12 is shown in a sectional view along the line H-H of FIG. 12. The diameter of thebutt 66 at line H-H of FIG. 12 is designated DH. - According to the embodiment of the invention shown in FIGS. 10 through 20, the diameter of the
butt 66 gradually increases from diameter DA adjoining thebutt end 64 to diameter DB at section B-B, and again increases from section B-B to the diameter DC at section C-C. Moving from section C-C to section D-D, the diameter of thebutt 66 is unchanged. Moving from section D-D to section E-E, the diameter of thebutt 66 diminishes slightly to DE. Moving from section E-E to section F-F, the diameter of thebutt 66 diminishes more markedly to diameter DF. Moving from section F-F to section G-G, the diameter diminishes only very slightly to diameter DG and continues to diminish moving to section H-H to a smaller diameter DH. To summarize, DA is less than DB, DB is less than DC, DC is equal to DD, while DD is greater than DE, DE is greater than DF, DF is greater than DG and DG is greater than DH. - According to a specific implementation of the third and fourth embodiments of the invention, DA equals 0.929 inches, DB equals 1.10 inches, DC equals 1.129 inches, DD equals 1.129 inches, DE equals 1.126 inches, DF equals 1.104 inches, DG equals 1.099 inches and DH equals 1.060 inches. According to this specific implementation, the distance between section A-A and section B-B is four inches. This is also the distance separating section B-B and section C-C, section E-E and section F-F, section F-F and section G-G, and section G-G and section H-H. The distance separating section C-C and section D-D, and separating section D-D and section E-E is two inches. As will be apparent from reviewing these example dimensions, the slope of the surface of the
butt 66 can be quite small. However, the invention may readily be implemented by providing much greater slopes along the surface of thebutt 66 at portion A. - As will be apparent from FIGS. 11 and 12, the slope of the
butt 66 resulting from its changing thickness changes without any discontinuity. Thus, around sections C-C and D-D, the slope of thebutt 66 gradually becomes zero such that there is no abrupt discontinuous change in the slope of the butt surface. Instead, the slope of thebutt 66 around sections C-C and D-D smoothly merges. - In using a
billiard cue 60 having thebutt 66 of FIG. 11 or 12 to strike a cue ball, a user would hold thebutt 66 at a haft portion between section C-C and section A-A. The slope of thebutt 66 between these sections increases towards thetip 62, such that this slope will tend to resist the user's hand slipping forward on thebutt 66. This slope will also serve as a non-visual aid to the user placing his or her hand, as the changing thickness of thebutt 66 will provide a sensation to the user that is directly proportional to the distance of the hand along thebutt 66. At the same time, due to the slope of thebutt 66 being smooth and continuous, the aesthetic appearance of thebutt 66 is not adversely affected. Further, no rough surface is provided that may catch on obstructions to ruin a shot. - Referring to FIG. 21, there is illustrated in a side view, a
billiard cue 130 having agrip 131 attached thereto in accordance with a fifth embodiment of the invention.Billiard cue 130 comprises atip 132 for striking a cue ball at one end, abutt end 134 opposite thetip 132, abutt 136 and ashaft 138. Thegrip 131 is mounted on a portion A of thebutt 136 that includes thebutt end 134. Thegrip 131 may also be mounted on a butt of a billiard cue assembly. - Referring to FIG. 22, the portion A of the
butt 136 of FIG. 21 having thegrip 131 mounted thereon is illustrated in a sectional view taken along the length of thebutt 136. Thegrip 131 is generally tube-shaped. Thegrip 131 includes aninner surface 140 and anouter surface 142. Theinner surface 140 is designed to retain thegrip 131 on a haft portion of thebutt 136. The thickness of thegrip 131 varies over its length such that theouter surface 142 provides a series of tapered sections along the haft portion of thecue 130 when thegrip 131 is mounted thereon. - As can be seen from FIG. 22, the
grip 131 is thicker at sections D-D and B-B, then it is at sections E-E, C-C and A-A. This provides thecue 130 with a negative taper from section A-A to section B-B, as the combined thickness of thebutt 136 andgrip 131 increases moving forward from thebutt end 134. Then, from section B-B to section C-C, there is a positive taper as the combined thickness of thebutt 136 and thegrip 131 decreases moving forward from thebutt end 134. From section C-C to section D-D, there is again a negative taper as the combined thickness of thegrip 131 and thebutt 136 increases moving forward from thebutt end 134. Finally, from section D-D to section E-E, there is again a positive taper as the combined thickness of thebutt 136 andgrip 131 diminishes moving forward from thebutt end 134. Thegrip 131 ends just after section E-E. - Preferably, the slope provided by the changing combined thickness of the
butt 136 and thegrip 131 changes without any discontinuity. Thus, on each side of sections D-D, C-C and B-B, the slope of anouter surface 142 of thegrip 131 gradually becomes zero such that there is no abrupt discontinuous change in this slope. Instead the slope of theouter surface 142 between sections D-D and C-C smoothly merges into the slope of theouter surface 142 between sections C-C and B-B. Preferably, as shown in FIG. 22, theouter surface 142 of thegrip 131 provides an elongated constant diameter section around section C-C to facilitate gripping. - In using a
billiard cue 130 having agrip 131 mounted thereon, a user would hold thebutt 136 via thegrip 131 at the haft portion between sections B-B and D-D. The combined thickness of thebutt 136 andgrip 131 between the sections C-C and D-D increases towards thetip 132 such that the resulting slope will tend to resist the user's hand slipping forward on thebutt 136. This slope will also serve as a non-visual aid to the user placing his or her hand, as the change in combined thickness of thebutt 136 andgrip 131 will provide a sensation to the user that is directly proportional to the distance of the hand along thebutt 136. At the same time, however, due to the smooth surface provided, the slope of theouter surface 142 of thegrip 131 will not adversely affect the aesthetic appearance of thebutt 136. Further, rough surfaces that may catch on obstructions to ruin a shot are minimized. - Referring to FIG. 23, a
billiard cue 160 having agrip 161 in accordance with the sixth embodiment of the invention is shown in a side view. Thebilliard cue 160 comprises atip 162 for striking a cue ball at one end, abutt end 164 opposite thetip 162, abutt 166 and ashaft 168. Theshaft 166 includes a haft portion at which thebutt 166 is gripped to make a shot. In FIG. 23, thegrip 161 is shown mounted on the haft portion of thebutt 166 at a portion A of thebutt 166. - Referring to FIG. 24, the portion A of the
butt 166 is shown in a sectional view taken along the length of thebutt 166. Thebutt 166, at the haft portion included in portion A, has thegrip 161 mounted thereon. As with thegrip 131 of FIGS. 21 and 22, thegrip 161 of FIGS. 23 and 24 is generally tubular in shape. Thegrip 161 includes anouter surface 172 and aninner surface 170. When mounted on thebutt 166, theinner surface 170 is adapted to retain thegrip 161 on the haft portion. Thegrip 161 varies in thickness along its length, such that when thegrip 161 is mounted on thecue 160, theouter surface 172 provides tapered sections along the length of thebutt 166 that are different from the taper of thebutt 166. - From the side view, it is apparent that the combined thickness of the
butt 166 andgrip 161 increases from section A-A to section B-B, and increases again from section B-B to section C-C. From section C-C to section D-D, the combined thickness of thebutt 166 andgrip 161 is substantially constant. Moving from section D-D to section E-E, the combined thickness of thebutt 166 andgrip 161 diminishes slightly. Moving from section E-E to section F-F, the combined thickness of thebutt 166 andgrip 161 diminishes more markedly. Moving from section F-F to section G-G and from section G-G to section H-H, the combined thickness of thegrip 161 andbutt 166 continues to diminish. Thegrip 161 ends just after section H-H. - As will be apparent from FIGS. 23 and 24, the slope of the
outer surface 172 of thegrip 161 resulting from its changing thickness as well as the changing thickness of thebutt 166, changes without any discontinuity. Thus, around sections C-C and D-D, the slope of theouter surface 172 of thegrip 161 gradually becomes zero such that there is no abrupt discontinuous change in the slope of theouter surface 172. Instead, the slope of theouter surface 172 around sections C-C and D-D smoothly changes direction. - In use, the
grip 161 is mounted on thebutt 166 of thecue 160. This may be done in a variety of different ways. First, thetubular grip 161 may be slid over thecue 160 from an end thereof. Alternatively, thegrip 161 could be wrapped around thebutt 166 and then secured in place. Alternatively, thegrip 161 may be sprayed on thebutt 166. - In using a
conventional billiard cue 160 having thegrip 161 mounted on thebutt 166 of thecue 160, a user will hold thegrip 161 at a haft portion of thebutt 166 between sections C-C and A-A. The slope of theouter surface 172 between these sections increases towards thetip 162, such that this slope will tend to resist the user's hand slipping forward on thebutt 166. The slope will also serve as a non-visual aid to the user placing his or her hand, as the changing thickness of thebutt 166 will provide a sensation to the user that is directly proportional to the distance of the hand along thebutt 166. At the same time, as a result of the slope of theouter surface 172 being smooth and continuous, the aesthetic appearance of thebutt 166 is not adversely affected. Further, rough surfaces that may catch on obstructions though on a shot are minimized. - Other variations and modifications of the invention are possible within the sphere and scope of the invention as defined by the claims appended hereto.
