DETAILED DESCRIPTION

Referring to FIG. 1, an apparatus according to a first embodiment of the invention is shown generally at 10. A body 20 connects a forearm engaging surface 30 and an upper arm contacting surface 40. For clarity, both the forearm engaging surface 30 and the upper arm contacting surface 40 are on the underside of the first embodiment of the invention and hence not visible in FIG. 1. The body 20 operates best when it is made from a rigid and/or stiff material as well as lightweight material. Absolute rigidity and/or stiffness is not required and some flexibility in the material may aid comfort for a golfer, however, the body 20 must not flex appreciably due to gravity. Further, lightweight materials are not required, but may improve the comfort of the device when being used by the golfer. Preferred materials include, but are not limited to, plastics and polycarbonate materials. Spaces 50, when present, are defined by the body 20 and are operable to receive a webbing or other attachment mechanism so as to secure the embodiment to an arm of the golfer.

Referring to FIG. 2, a line 60 defines a middle section of the body 20 and the lines 70 indicate the area of the upper arm contacting surface 40. For clarity, FIG. 2 is a top view of the first embodiment of the invention and hence the upper arm contacting surface is not visible in FIG. 2.

Referring to FIG. 3, an upper arm contacting surface plane 80 is represented by a dotted line, which plane is perpendicular to the surface of the page. In one embodiment, when the embodiment is oriented as shown in FIG. 3, the upper arm contacting surface plane 80 may be defined by a horizontal plane that extends between lines 70 (see FIG. 2) and comprises those lines together with the lowest point of the embodiment. In the same embodiment, when the embodiment is oriented as shown in FIG. 3, a forearm engaging surface plane 90 may be defined by a horizontal plane, perpendicular to the surface of the page, that comprises both the line 60 (see FIG. 2) and a portion of the forearm engaging surface 30 that exists at line 60, which portion is shown in FIG. 4 at point 100. As the embodiment is rotated, so does the upper arm contacting surface plane 80 and the forearm engaging surface plane 90 rotate similarly. These two planes 80 and 90 are maintained at a fixed position relative to each other by the body 20. Generally, the two planes 80 and 90 are maintained at a fixed distance that is selected from a range of from about 0.5 inches to about 2.0 inches. In some embodiments, the two planes 80 and 90 are maintained at a distance of from about 0.5 inches to about 2 inches. In other embodiments, the two planes 80 and 90 are maintained at a distance of from about 0.5 inches to about 1.5 inches from each other. In other embodiments, the two planes 80 and 90 are maintained at a distance of from about 1.0 inch to about 2.0 inches from each other. In other embodiments, the two planes 80 and 90 are maintained at a distance of from about 0.8 inches to about 1.3 inches from each other. In other embodiments still, the two planes 80 and 90 are maintained at a distance of from about 0.9 inches to about 1.1 inches from each other. In other embodiments still, the two planes 80 and 90 are maintained at a distance of about 1 inch from each other.

The shape of the body 20 is not of particular importance provided that the planes 80 and 90 are kept within the fixed relative distances from each other as described herein. It is convenient if the body is kept smaller so that there is less likelihood of the invention interfering with the golfer in a manner that is not related to making the golfer aware of the straightening and/or bending of the leading arm of the golfer. A gradual, sloping shape of the body 20 that generally follows the contour of the golfer's arm is often a convenient shape for the body 20, but it is not absolutely necessary. Another convenient shape for the body is a generally curved shape, but it is not absolutely necessary. The body 20 may be angular and/or irregularly shaped, if desired, so long as planes 80 and 90 are kept spatially relative to each other as described above.

Further, the shape of the body 20 with respect to the forearm engaging surface 30 is also not critical. Often it is convenient to have the body 20 shaped so that it generally follows the contour of the golfer's arm, as shown in FIG. 4. In some embodiments, the body 20 may be flat on both sides. In some embodiments, the body 20 may be flat on the top side and curved on the underside where the forearm engaging surface 30 is. In some embodiments, the body 20 may be flat on both sides. In some embodiments, the body 20 may be curved on both sides.

In some embodiments, the forearm engaging surface 30 may be shaped to enhance contact between the forearm of the golfer and the forearm engaging surface 30. This may be achieved by making the forearm engaging surface 30 generally concave or having a rounded shape that generally follows the curve of the golfer's arm with respect to the circumference of the forearm of the golfer. With respect to the longitudinal direction of the forearm engaging surface 30 (i.e. the direction which is generally in line with the bones of the forearm of the golfer when the embodiment is worn by the golfer), the shape is generally linear so that as the elbow joint of the golfer is bent or straightened, the forearm of the golfer is able to impart a force to the forearm engaging surface 30, such that the upper arm contacting surface 40 is moved via a translation of the force from the forearm of the golfer.

The upper arm contacting surface 40 may be shaped to enhance comfort when contacting the upper arm of the golfer or may be flat. In some embodiments, the upper arm contacting surface 40 is a rounded surface.

In other embodiments, the upper arm contacting surface 40 together with a portion of the body 20 may be covered by an extender. The extender may be made of rubber or any other suitable material, such as malleable plastic with a texture or shape which can be felt on the back of the arm. The extender may be shaped similarly to the portion of the body 20 that maintains the fixed relative distance between planes 80 and 90. When an extender is present, the upper arm contacting surface 40, is covered by the extender and is replaced by an upper arm contacting surface on the extender. Use of the extender makes it possible for the golfer to change the relative distance between planes 80 and 90.

The body 20, with surfaces 30 and 40, must be attached to the forearm of the golfer in order to be operated. The body 20 may be attached to the forearm of the golfer by an attachment means. A suitable attachment means will be an attachment device that secures the forearm engaging surface 30 to the forearm of the golfer at a portion of the forearm that is just beneath the elbow and is generally closer to the ulna bone than the radius bone so that forearm engaging surface is positioned on the underside of the forearm if the palm is facing upwards and the arm is straight and extended. The precise location of the body on the forearm is not absolutely critical and some moderate movement of the device on the forearm is suitable for comfortable use of the invention, though less movement is preferable. Suitable attachments means include, but are not limited to: i) at least one space defined by the body operable to receive a webbing; ii) two spaces defined by the body, each space operable to receive a webbing; and iii) an article of clothing, such as a shirt, a sweater, a jacket, a glove or a tube of material.

In embodiments comprising at least one space, or two spaces, defined by the body, the space(s) operable to receive a webbing, the webbing may pass though the space(s) and around at least a portion of the body 20 so that it is then able to secure the body 20 to the webbing and the webbing may then be wrapped around the forearm of the golfer to secure both the webbing and the body 20 to the forearm of the golfer at the position described above. The webbing may be adjustable such that it is operable to wrap around forearms of different sizes.

In some embodiments, the body 20 may be secured to the golfer by an article of clothing, such as a tight fitting shirt, sweater, jacket, or extra long glove. The article of clothing may be modified to comprise additional attachment devices for securing the body 20 to the article of clothing. Further, the article of clothing may be a customized sleeve of material that slips on over the golfer's arm and comprises the body 20 as an integrated part of the sleeve of material. In some embodiments, the article of clothing may conceal the invention from view and hence interfere with the direct connection of the surfaces 30 and 40 with the skin of the golfer. Such interference will not prevent use of the invention as described herein and some embodiments may be used over top of an article of clothing such as, but not limited to, a shirt, sweater or jacket, which article of clothing may or may not be specially adapted for use with the present invention.

When an embodiment of the invention is attached to the forearm of the golfer, as described above, the body 20 will be positioned such that the forearm engaging surface 30 is in constant engagement with the forearm of the golfer, regardless of the position of the golfer's arm. If the arm to which the embodiment is attached is bent at the elbow, the upper arm contacting surface 40 will not contact the upper arm (of the same arm) of the golfer. If the arm is straight (e.g. there is no bend in the elbow present), then the upper arm contacting surface 40 is in contact with the upper arm of the golfer and the golfer is able to feel the upper arm contacting surface 40 on their upper arm. When the golfer bends their arm at the elbow from a straight position to a bent position, then the upper arm contacting surface 40 is moved away from the upper arm of the golfer by the body 20. The more bending that occurs at the elbow, the farther away the upper arm contacting surface 40 is moved from the upper arm of the golfer. When the golfer straightens their elbow joint from a bent position to a straight position, the body 20 will move the upper arm contacting surface 40 closer to the upper arm of the golfer until the arm is straight and when the arm is straight, the upper arm contacting surface 40 will be in contact with the golfer's upper arm. This contact with the golfer's upper arm serves to remind the golfer that their arm is straight. Further, the golfer is able to sense a lift-off of the upper arm engaging surface 40 from the back of the upper arm when the elbow joint of the golfer is moved from a straight position to a bent position. The upper arm is sensitive and the golfer may be able to notice a change in pressure when the device is moved from a strong connection with the upper arm, which occurs with a very straight elbow joint, to a weaker connection with the upper arm, which occurs with a generally straight and/or almost straight elbow joint, to no connection with the upper arm, which occurs with a bent elbow joint.

In other embodiments, when the extender is covering the upper arm contacting surface 40 with a portion of the body 20, the extender is operable to permit the user to adjust the relative distance between the planes 80 and 90. This variability permits the device to accommodate more arm sizes and shapes. The extender may be made from a material that facilitates different amounts of pressure to be applied to the back of the arm so as to provide more or less comfort and/or pressure to the back of the arm when the arm is bare, or to apply more pressure in order to facilitate the wearing of clothing that may lessen or impede the golfer's ability to sense the upper arm contacting surface 40. The extender may have a variety of different textures to make the comfort of the pressure on the back of the golfer's upper arm more enjoyable. These properties of the extender relate to the upper arm contacting surface on the extender and the extender covering the upper arm contacting surface 40. The extender may also be adapted to be able to be inserted onto the body 20 such that it extends the body 20 by a particular, fixed distance or such that it can be used to extend the body 20 by a variable distance to be determined by the golfer.
