  Golf club head recessUSPTO Application #: 20070117646Title: Golf club head recess Abstract: A recess for a golf club head providing the opportunity for better shots as torque and/or twisting is reduced between the hosel and the golf club head's center of mass. At the point where the hosel of a golf club connects to the golf club head, a recess may be provided that reduces the distance between the interconnection as well as the center of mass of the golf club head. The connection is then sunk into the golf club head to a certain degree thereby eliminating the common distance that occurs when the hosel is merely attached to the top of a golf club head. By reducing torque and/or twisting, shots with a golf club head having a recess may be more predictable, reliable, leading to a better golf game. Additionally, a flared golf club hosel is disclosed.

BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to golf clubs and more particularly to golf club heads with designs aimed at minimizing or limiting torque about the shaft of the golf club. [0004] 2. Description of the Related Art [0005] The game of golf is well known in the art and is played by thousands if not millions, of people each year. The game of golf generally consists of a long stretch of ground with a hole at one at end and the player starting his or her game for the hole at the other. By means of driving a small ball with a club, both accuracy and power are important features of the game as the ultimate goal is to get the ball in the hole. [0006] While simple in explanation, the actual mechanics of game are very complex due to, among other things, skeleto-muscular structure of the human body and the fact that is very difficult (both physically and mentally) to always be at the top of one's game. Good players are generally those who have control over the flight of the ball once it has left the face of club, although all control over the ball is delivered by the golfer at the split second impact time the ball is actually in contact with the club face. [0007] Reliability of shots is generally dependent upon the reliability of swing. Consequently, much focus and attention is given to the golfer's golf swing. [0008] One of the difficulties in striking the golf ball is the fact that the swing path of the golf club head generally is not aligned with the golf club shaft. Further, the center of mass of the golf club head is not aligned with the golf club shaft. Additional reasons for difficulties may be due to simple anatomical dispositions with respect to the human skeleton-muscular system. [0009] Generally, in a golf club, the shaft extends downwardly from the grip and enters the golf club head through the hosel. The hosel is generally located at the top of the heel of the golf club head. The golf club head then extends through the center and over to the toe of the golf club head with the golf club face acting as the striking surface, the golf ball preferably striking the face in its center. [0010] Due to this offset nature of the golf club shaft axis with respect to the center of mass of the golf club head, there is an inherent torque about the golf club shaft. This torque arises from the distance between the axis of the golf club shaft and center of mass of the golf club head. This torque also depends upon how and where the golf ball impacts the golf club head. For example, if the golf ball strikes the golf club face near the toe there will be greater torque than if it strikes the golf club face near the heel. [0011] Many attempts in the past have been made to address or minimize this torque as such torque will affect the golf shot, more probably than not in a detrimental rather than an advantageous manner. As a result, it is a problem that remains to be solved in the game of golf and one that may be addressed in several manners. The art remains to be developed with respect to such systems that seek to minimize the torque about the golf club shaft when the golf club is struck. SUMMARY OF THE INVENTION [0012] In view of the foregoing disadvantages inherent in the known types of golf club and golf club heads now present in the prior art, the present invention provides a new golf club head construction that results in a new golf club wherein the same can be implemented for reducing the torque experienced around the golf club shaft when striking the golf ball. [0013] The general purpose of the present invention, which will be described subsequently in greater detail below, is to provide a new golf club head design in construction that has many advantages of prior golf club heads and many novel features that result in a new torque reducing golf club head which is not anticipated, rendered obvious, suggested, taught, or even implied by any of the prior art golf club heads, either alone or in any combination thereof. [0014] In order to provide lower torques about the golf club shaft, a recess is present at the point where the hosel transitions into the golf club head. This recess brings the connection between the hosel and golf club head closer to the center of gravity of the golf club head and indeed lowers it with respect to a top surface of the golf club head. [0015] The recess may be curved in one or two dimensions, i.e., respectively, like a curved warped flat board that keeps its flatness even though its ends are curved towards one another or somewhat like a canoe that is curved both along its length and its width (alternatively, somewhat like a elongated bowl that is curved both its length and width). [0016] Hosels fitting into such a recess may be of generally of any character including flared, cylindrical, or the like. The recess may be configured to match the hosel. That recess may take several shapes and configurations limited only by the imagination. [0017] In one embodiment of the present invention, a golf club head with a ball-striking surface and a body coupled to the striking surface rearwardly thereof has a recess adapted to receive a hosel. The recess descends into the golf club head to thereby lower the connection of a hosel with the golf club head with respect to an upper surface of the golf club head. [0018] In another embodiment of the present invention, a golf club head has a ball-striking surface adapted to strike a golf ball and a body coupled to the ball-striking surface generally rearwardly thereof. One of either or both the ball-striking surface and the body may define the recess. The recess is adapted to receive a hosel therein such that the recess provides a connection with the hosel that generally reduces a distance between the hosel connection and a center of mass of the golf club head to correspondingly reduce torque and/or twisting of the golf club head about the connection when the golf club head strikes the golf ball. [0019] In another embodiment, a golf club head has a ball-striking surface adapted to strike a golf ball and a body coupled to the ball-striking surface generally rearwardly thereof. At least one of either or both the ball-striking surface and the body defines the recess and the recess adapted to receive a hosel therein. The recess may have a surface curved in one dimension (like a board) or curved in two dimensions (like a boat). For the first type (like a board), the recess may be curved along a first direction generally parallel or similar in direction to a long axis of the golf club head present along a toe and heel of the golf club head. For the second type (like a boat), the recess may be generally curved along a first direction generally parallel or similar in direction to a long axis of the golf club head present along a toe and heel of the golf club head and may be curved in a second direction generally perpendicular or similar in direction to perpendicular to the long axis of the golf club head. The hosel may selected from flared hosels and cylindrical hosels and the golf club head selected from driver heads, iron heads, and putter heads. In this way, the recess provides a connection with the hosel that generally reduces a distance between that connection and a center of mass of the golf club head to correspondingly reduce torque and/or twisting of the golf club head about the connection when the golf club head strikes the golf ball. BRIEF DESCRIPTION OF THE DRAWINGS [0020] FIG. 1 is a rear, left side, and elevational view of one embodiment of the recess of the present invention, the hosel golf club head (in the form of a putter) is shown in phantom.
