The addition of fashionable accessories to the rings 14, 16, 18 significantly increases the user's likelihood of wearing the grip 10 because it decreases the possibility that others will notice that the grip is an aid, and thereby it seeks to prevent any embarrassment caused by its use.

The anchor 40 of the adaptive grip 10 is positionable along the vertical stem 20 of the finger grip 12. The anchor 40 integrally couples the clasping mechanism 80 to the finger grip 12. The position of the clasping mechanism 80 is adjustable by the anchor 40 which provides the user with a comfortable and easy to use grip 10. The anchor 40 adjusts the clasping mechanism 80 both circumferentially around and laterally along the vertical stem 20. The anchor 40 allows the clasping mechanism 80 a great amount of freedom in positioning, such that the user is able attain the maximum level of comfort which using the grip 10. Specifically, the anchor 40 provides the clasping mechanism 80 the ability to be positioned at a plurality of different intervals either closer to or further away from the vertical stem 20.

FIG. 1A is an exploded view of the anchor 40. Here, the substantially cylindrical anchor 40 is positioned perpendicularly to and along the vertical stem 20. As show, the anchor 40 has a top surface 42, a bottom surface 44, and a first vertical channel 46 that extends from the top surface 42 through to the bottom surface 44. The first vertical channel 46 of the anchor 40 is substantially cylindrical and secures a portion of the substantially cylindrical vertical stem 20 therein. The anchor 40 however is still capable of moving freely along the vertical stem 20, when not secured by a fastener.

The anchor 40 is further comprised of a front portion 48, a back portion 50, and a substantially cylindrical horizontal channel 52 extending from the front portion 48 to the back portion 50. The front portion 48 of the horizontal channel 52 of the anchor 40 accepts the clasping mechanism 80 therein. Additionally, the front portion 48 of the anchor 40 has a second vertical channel 58 extending perpendicularly from the horizontal channel 52 to the bottom surface 44 of the anchor 40. The second vertical channel 58 accepts a fastener therein, preferably a second thumb screw 60, or other like fastener. The second thumb screw 60 fastens the clasping mechanism 80 in a selected position within the channel 58. As discussed below, the shaft 92 of the clasping mechanism 80 is accepted into the horizontal channel 52. The clasping mechanism 80 has the freedom to move within the channel 52, by means of the shaft 92, until fastened; and can therefore be positioned close to or further from the vertical stem 20 depending on the amount of space the user and task requires.

Specifically, by loosening the second thumb screw 60, the shaft 92 of the clasping mechanism 80 is positionable either closer to the vertical stem 20 or further from the vertical stem 20. Once the clasping mechanism 80 is in a comfortable location for use, the user tightens the second thumb screw 60 which actuates the shaft 92 of the clasping mechanism 80 to firmly juxtapose the front portion 48 of the horizontal channel 52 and secure the clasping mechanism 80 therein.

The back portion 50 of the horizontal channel 52 of the anchor 40 accepts a first thumb screw 56, or other like fastener, to adjust the position of the anchor 40 along the vertical stem 20. By loosening the first thumb screw 56, the anchor 40 is able to slide upwardly or downwardly along the vertical stem 20. The anchor 40 also provides the clasping mechanism 80 the ability to swivel around the vertical stem 20 so that the adaptive grip 10 is suitable for right-handed or left-handed users. Similarly, once the anchor 40 is in a suitable position, the user tightens the first thumb screw 56 and actuates the vertical stem 20 to firmly juxtapose the vertical channel 46 and secure the vertical stem 20 within anchor 40.

FIG. 2 illustrates the clasping mechanism 80 of the adaptive grip 10. The clasping mechanism 80 includes a clip 82 for selectively grasping an object. The clip 82 is comprised of a first branch 83 and a second branch 87. Both branches 83, 87 have a plurality of curved teeth 84 and a first end 86. The first and second branches 83, 87 are elongated in shape and coupled together at the first ends 86 by a hinge 91. The hinge 91 enables the clip 82 to toggle between a close position 22 (shown in FIG. 2A) and an open position 24 (shown in FIG. 2B). The first branch 83 has a first lateral edge 85 from which the curved teeth 84 extend laterally towards the second branch 87. Similarly, the second branch has a second lateral edge 88 from which the curved teeth 84 extend laterally and curve towards the first branch 83.

In the close position 22, the curved teeth 84 of the first branch 83 are interlocked with the curved teeth 84 of the second branch 87 for firmly grasping the desired object in a suitable position for use. In the open position 24, the curved teeth 84 of both branches 83, 87 are separated from one another and allow the clip 82 to receive the desired object. In addition, the curved teeth 84 of the first branch 83 and second branch 87 contain a rubber-lining to prevent the object from slipping.

The clasping mechanism 80 of the adaptive grip 10 contains a lever 90 for adjusting the clip 82. The lever 90 extends downwardly from the hinge 91 of the clip 82. The hinge 91 is integrally coupled to the lever 90 for toggling the clip 82 between the close and open positions 22, 24. Preferably, the user inserts their thumb through the bottom ring 18 and is capable of controlling the clip 82 from the close or open position 22, 24. By simply pulling the lever 90 towards the vertical stem 20 of the finger grip 12 the user is able to position the clip 82 in the open position 24. Similarly, by releasing the lever 90 the user is able to position the clip 82 around the desired object. Or alternatively, when no object is grasped, releasing the lever 90 will return the clip 82 to the close position 22.

The clip 82 is integrally coupled to the shaft 92 of the clasping mechanism 80. The shaft 92 extends downwardly from the clip 82 such that the clip 82 is preferably at a forty-five degree angle with the shaft 92. This positioning of the clip 82 allows the user to adjust the grasped object at the most comfortable position while in use. The shaft 92 removably couples within the anchor 40 by insertion into the front portion 48 of the horizontal channel 52 of the anchor 40.

FIG. 3 is an illustration of the preferred embodiment of the adaptive grip 10 in use, grasping a pen for aiding a right-handed user to write. In alternate embodiments, the invention is easily adapted for use by a left-handed user. Here, the first ring 14 accepts the user's right index finger 32 while the third ring 16 accepts the user's right middle finger 34. Additionally, the bottom ring 18 is positionable for inserting the user's right thumb 36. These are preferable finger placements for the using the grip 10 by a right handed user, however, the user may selectively alter the positioning to achieve a more comfortable grip.

When using the adaptive grip 10 for writing a note, the first step is to configure the adaptive grip 10 for holding a pen based on whether the user is utilizing their right or left hand. As discussed supra, for purposes of illustration only a right-handed user is selected. Next, the user loosens the first thumb screw 56 of the anchor 40 and adjusts the position of the anchor 40 around the vertical stem 20 to direct the clasping mechanism 80 to a suitable position. Such position would be different and likely the mirror opposite for a left-handed user than a right-handed user. For either a right-handed or left-handed user the clasping mechanism 80 is positioned such that the clip 82 is pointing away from the user's hand. The anchor 40 is rotatable around the vertical stem thereby providing versatility in the positioning of the clasping mechanism to allow the adaptive grip 10 proper fit for a right-handed or left-handed user.

Next, the user determines whether the anchor 40 or clasping mechanism 80 is best adjusted to fit the user's hand and needs of the specific task of writing a note. With the first thumb screw loosened, the user adjusts the anchor 40 upwardly or downwardly along the vertical stem 20, as desired. By loosening the second thumb screw 60, the user positions the clasping mechanism 80 either closer to or further from the finger grip 12 to achieve a comfortable hold. Preferably, the clasping mechanism 80 is positioned such that the user may reach the lever 90 of the clasping mechanism 80 using their thumb 36 to adjust the clip 82 as desired.

Once the desired positions of the clasping mechanism 80 and anchor 40 are achieved, the user tightens both the first thumb screw 56 and second thumb screw 60 and then inserts their fingers, discussed supra, into the designated rings 14, 16, and 18.

With the clip 82 in the closed position 22, the user, pulls the lever 90 of the clasping mechanism 80 towards the vertical stem 20 and causes the clip 82 to remain in the open position 24. The user places a ready to-use pen within the clip 82. The user then releases the lever 90 of the clasping mechanism 80 with their right thumb and causes the curved teeth 84 of the first and second branch, 83 and 87, of the clip 82 to firmly grasp the pen. The user is then able to use the pen to write a note by controlling the adaptive grip 10.

To release the pen, the user simply pulls the lever 90 of the clasping mechanism 80 with their right thumb, which causes the clip 82 to open from the close position 22 into the open position 24. Depending on the grip 10 orientation, the pen may naturally fall out of the curved teeth 84 or be removed by the user with their left hand. Finally, the user releases the lever 90 with their right thumb and the clip 82 is returned to the close position 22. The user is then free to remove their fingers from the rings 14, 16 and 18 and store the grip 10 for later use, or use the grip 10 to complete another task.

In conclusion, presented herein is an adaptive grip. The invention is illustrated by example in the drawing figures, and throughout the written description.
