A sporting article having moveable weight members of various weight values that may be positioned along a guide in various configurations, for example, transversally, longitudinally and/or diagonally, at various positions and angles on the sporting article so that the user may properly adjust the weight distribution of the sporting article to perform a desired shot or improve maneuverability.
The present application claims the benefits of U.S. provisional patent application No. 60/780,344 filed Mar. 9, 2006, which is hereby incorporated by reference.
TECHNICAL FIELDThe present invention relates to a sporting article with an adjustable weight configuration. More specifically, the present invention relates to a golf club head with an adjustable weight configuration.
BACKGROUNDWhen practicing sports, the weight balance of a sporting article may have an impact on the performance of the user, be the sporting article be a golf club, racket, a hockey stick, a ski, etc.
For example, when swinging a golf club at a golf ball, some golfers have a swing such that the heel portion of the golf club head tends to move faster than the toe portion. This results in the heel portion arriving ahead of the toe portion at impact, causing the impact surface to be misoriented. This is what is commonly referred to as a “slice”. Conversely, some golfers have a swing such that the toe portion of the golf club head tends to move faster than the heel portion. This results in the toe portion arriving ahead of the heel portion at impact, causing the impact surface to be misoriented. This is what is commonly referred to as a “hook”.
Thus, golf club heads are configured in a variety of geometries in order to move the weight of the golf club head to points that enhance stability, i.e. more weight at either the heel or toe portion slows down that portion during the swing. These points differ from one model of golf club to another.
While common golf clubs operate satisfactorily, most of the weighted golf club heads suffer from the limitation that their weight distribution cannot be readily altered to customize the golf club to the needs of a particular golfer. Other sporting articles suffer from
SUMMARYThe present invention relates a sporting article comprising at least one body portion providing a guide, the at least one body portion defining a generally longitudinal length, a generally transversal length and a generally diagonal length thereof, the guide comprising at least two guide sections, and at least one moveable weight member for being moveably engaged to the guide. Each of the guide sections providing for selectively moving the moveable weight member along at least one of the generally longitudinal, generally transversal and generally diagonal lengths of the at least one body portion.
The present invention also relates to a sporting article comprising a guide channel formed within at least one body portion of the sporting article and at least one moveable weight member for being moveably engaged within the guide channel. The moveable weight member comprises an external element for being positioned externally relative to the guide channel, an internal element for being positioned within the guide channel and an intermediate element for mounting the external and internal elements thereon near opposite ends thereof. When mounting the moveable weight member to the guide channel, selective actuation of the intermediate element provides for moving the external and internal elements closer to one another along the intermediate element causing the external and internal elements to respectively frictionally abut an external surface the body portion and an internal surface of the guide channel thereby locking the moveable weight member at a given position along the guide channel.
The present invention further relates to a sporting article comprising a guide provided on at least one body portion of the sporting article, positioning indicators being provided on the at least one body portion along the guide and at least one moveable weight member for being moveably mounted to the guide. The moveable weight member being configured to be lockingly positioned at a desired position indicated by a given positioning indicators along the guide.

The weight member comprising an external element for being positioned externally relative to the guide channel, an internal element for being positioned within the guide channel and an intermediate element for mounting the external and internal elements thereon near opposite ends thereof. When engaging the weight member to the guide channel, selective actuation of the intermediate element provides for moving the external and internal elements closer to one another along the intermediate element causing the external and internal elements to respectively frictionally abut an external surface the body portion and an internal surface of the guide channel thereby locking the weight member at a given position along the guide channel.
Non-limitative illustrative embodiments of the Invention will now be described by way of examples only with reference to the accompanying drawings, in which:
Generally stated, the illustrative embodiments of the present invention provide sporting articles for users of all calibers; from amateur to professional. The present invention allows the user to adjust the weight distribution of the sporting article in order to customize it to his or her particular needs. Moveable weight members of various weight values may be positioned along a guide in various configurations, for example, transversally, longitudinally and/or diagonally, at various positions and angles on the sporting article so that the user may properly adjust the weight distribution of the sporting article to perform a desired shot or improve maneuverability.
Referring to
Furthermore, in this particular example the illustrated golf club head 100 is that of a driver. However, it is to be understood that the adjustable weight configuration may be applied to any other type of golf club head such as, for example, irons, wedges (pitching (pw), gap (gw), sand (sw), lobe (lw)) or a putter, made of whatever type of material.
The first moveable weight member 40 is generally displaced along the transversal guide section 22, which runs on the rear portion 18 of the golf club head 100 from its toe portion 14 to its heel portion 15, while the second moveable weight member 50 is generally displaced along the longitudinal guide section 24, which runs on the rear portion 18 of the golf club head 100 from its crown portion 12 to its sole portion 13. It is to be understood, however, that both moveable weight members 40 and 50 may be displaced along either or both the transversal guide section 22 and the longitudinal guide section 24.
The moveable weight members 40 and 50 typically weigh between 0.2 g and 1.0 g. However, it is to be understood that the weight value of the moveable weight members 40, 50 are given as examples only; other weight values may be used depending on the desired weight distribution, the type of club, gender and size of the golfer, etc. It is further to be understood that the weight values may also vary depending on the type of sporting article and its intended use.
Referring to
The first moveable weight member 40 includes an external element 40a, an intermediate element in the form of a locking element 41, which includes a head portion 43, a threaded body 45 and a blocking portion 47, and an internal element 49. The threaded body 45 operatively engages the internal element 49, which has a complementary thread pattern. The blocking portion 47 ensuring that the internal element 49 remains operatively connected to the locking element 41.
The first moveable weight member 40 may be engaged to the golf club head 100 by inserting the internal element 49 into the transversal guide section 22, which forms a channel within the golf club head 100, through an opening 26 which is located near the heel portion 15, the locking element 41 protruding from a slot 22a in the transversal guide section 22 such that the external element 40a rests on the outer surface 10 of the golf club head 100. It is to be understood that the opening 26 may be located at the toe portion 14, along the longitudinal guide section 24 or may be absent altogether in an alternative embodiment were the moveable weight members 40 and 50 are not removable.
Although not illustrated, it is to be understood that the second moveable weight member 50 may be described in a similar fashion as the first moveable weight member 40. Furthermore, the second moveable weight member 50 may be engaged to the transversal 22 and longitudinal 24 guide sections in a fashion similar to the first moveable weight member 40.
LockingRotating the head portion 43 of the locking element 41 in a first direction results in the external element 40a and the internal element 49 moving towards each other. The size of the external 40a and internal 49 elements being greater than the slot 22a of the transversal guide section 22, the external 40a and internal 49 elements respectively frictionally abut the outer surface 10 of the golf club head 100 and part of the internal surface 22b of the transversal guide section 22, thereby locking the first moveable weight member 40 at a given position along the transversal guide section 22, as best seen in
Advantageously, the geometry of the internal element 49 may be such as to be complementary to the geometry of the transversal guide section 22 so as to maximize the contact between the internal element 49 and part of the internal surface 22b of the transversal guide section 22.
UnlockingRotating the head portion 43 of the locking element 41 in a second opposite direction results in the external element 40a and the internal element 49 moving away from each other, thus unlocking the first moveable weight member 40 and allowing for a space 19 to be created between the external element 40a and the outer surface 10 of the golf club head 100 so that the first moveable weight member 40 may be moved along the transversal guide section 22, as best seen in
It is also to be understood that other locking means may be used in order to secure the moveable weight member 40 in a desired position and to release it in order to modify the weight configuration of the sporting article.
Although the above description makes reference to the transversal guide section 22, it is further to be understood that it may similarly apply to the longitudinal guide section 24 (or even a diagonal guide section in an alternative embodiment).
Referring to
The moveable weight members 40 and 50 may also include transversal and/or longitudinal position indicators. In the illustrated embodiment the first moveable weight member 40 includes a transversal 42 and longitudinal 44 position indicator while the second moveable weight member 50 includes a longitudinal position indicator 34. Complementary transversal 32 and longitudinal 34 position markers may also be provided on the golf club head 100 so that a golfer may remember the position of the moveable weight members 40 and 50 in a desired weight configuration. Furthermore, the user may wish to use various weight configurations depending on the desired effect or shot.
It is to be understood that in the case of alternative embodiments having diagonal guide sections, the moveable weight members 40 and 50 may also include diagonal position indicators (not shown).
