S pt 20, 1971 WRIST CONTROL DEVICE Filed June 50, 1969 United States Patent ce 3,606,342 WRIST CONTROL DEVICE Stanley E. Alhertson, Jr., 34037 Burton Lane, Livonia, Mich. 48154 Filed June 30, 1969, Ser. No. 837,663 Int. Cl. A63b 69/36 US. Cl. 273-189R 21 Claims ABSTRACT OF THE DISCLOSURE A wrist control device including a hand member having at least a portion thereof being frusto-conical and an arm member pivotally connected to the hand member. A plate is pivotally connected to the top surface of the hand member, and a first strap means is connected to the plate so that the device may be utilized on either the right or left hand. A second strap means is connected at one end to the top surface of the hand member and extends about the opposite side and through a slot in the hand member and then back about the opposite side to a second end. The first and second strap means are respectively removably connected to the respective members and each have coacting means at the respective ends thereof for releasably connecting the ends of the respective strap means together. A cushioning material is disposed on the under surfaces of the respective members.

This invention relates to a wrist control device which may be worn by the participants of various sports such as golf and bowling. The wrist control device of the instant invention is used in sports where the movement between the forearm and the hand should be limited to movement about an axis substantially normal to the back of the hand or wrist and passing through the wrist joint.

Various devices have been provided in the prior art for controlling the articulation between the hand and forearm. One such device is shown in United States Pat. 3,235,258 for use by bowlers. This prior art device includes a pair of straps which extend about the forearm for attaching a plate to the forearm and an arcuate member extending from the plate for engaging the back of the hand. The arcuate member is, however, attached to the back of the hand and, therefore, the back of the hand may move inwardly and away from the arcuate member, the arcuate member limiting movement of the hand only in an outward direction. Another prior art wrist control device is disclosed in US. Pat. 3,350,100. This device includes two members pivotally connected together and being substantially straight or in the same plane. The hand member has a glove attached thereto and strap means are associated with the arm member for attaching arm member to the forearm. When a participant in a sport, such as golf, grasps a game element such as a golf club, the hand position approaches that of forming a fist whereby the back of the hand moves out of the plane of the top of forearm. Thus, this prior art device wherein the arm and hand members are straight allows for no such movement in the hand and, therefore, does not limit the articulation between the hand and the forearm to that of the most desired character.

Accordingly, it is an object and feature of this invention to provide a wrist control device including arm and hand members pivotally connected together with the hand member being of the configuration to limit such articulation in the desired manner while providing for the proper position of the hand relative to the forearm and which device may be utilized with either a r1ght or left hand.

Other objects and attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following 3,606,342 Patented Sept. 20, 1971 detailed description when considered in connection with the accompanying drawings wherein:

'FIG. 1 is a perspective view of the preferred embodiment of the instant invention shown disposed on a left hand;

FIG. 2 is a plan view of the preferred embodiment;

FIG. 3 is a cross-sectional view taken substantially along line 33 of FIG. 2; and

FIG. 4 is a view taken substantially along line 4-4 of FIG. 3.

Referring now to the drawings wherein like numerals indicate like or corresponding parts throughout the several views, a preferred embodiment of the wrist control device of the instant invention is generally shown at 10.

The device 10 includes a band member generally indicated at 12 for engaging the back of the hand 13. The device 10 also includes an arm member generally indicated at 14 for engaging the top of the arm 15 above the wrist 16. The device 10 also includes pivot means, generally indicated at 18, pivotally connecting the arm and hand members 12 and 14 together for pivotal movement relative to one another only about an axis which is generally normal to and above the wrist when the device 10 is placed upon the wrist as illustrated in FIG. 1.

The device 10 also includes means generally indicated at for attaching the arm member 14 to the arm 15 and means generally indicated at 22 for attaching the band member 12 to the hand 13.

The hand and arm members 12 and 14 are plate-like members and may be made of such materials as metal or plastic. The hand member 12 has an undersurface with at least a portion 24 which slants upwardly in a direction away from the pivot means 18. The undersurface 24 is arcuate transversely of the direction in which the hand member 12 slants upwardly. More specifically, the undersurface of the hand member 12 is generally frusto-conical, as best illustrated in FIG. 3. The hand member 12 is generally pear shaped when viewed in plan, as illustrated in FIG. 2. The small portion of the hand member 12 is indicated at 26. The arm member 14 is generally rectangular with a projection 28 extending from one end thereof as viewed in plan. The small portion 26 of the hand member 12 overlaps the projection 28 of the arm member 14 and the pivot means 18 pivotally interconnects the projection 28 and the small portion 26.

A first cushioning means 30 is secured to the undersurface of the arm member 14 and a second cushioning means 32 is secured to the undersurface 24 of the hand member 12. The cushioning means 30 and 32 are made of resilient foam or pad-like material. The arm member 14 has a slot 34 extending along one extremity thereof, the purpose of which will be set forth hereinafter, and the cushioning means 30 covers all of the undersurface of the arm member 14 except that portion containing the slot 34, which is best illustrated in FIG. 4. The cushioning means 32 covers all of the undersurface of the hand member 12 except the small portion 26 thereof.

The means 22 for attaching the hand member 12 to the hand 13 includes a plate 36, which is pivotally attached to the hand member 12 by the rivet 38, and a first strap means 40. Strap means is connected to the plate 36 by a plurality of pairs of coacting snap-together elements 42. Each pair of the elements 42 comprise a male and female element which may be snapped together and detached from one another. The longitudinal axis of a strap means 40 may be disposed, because of the pivotal attachment of the plate 36, at various angles relative to the direction in which the hand member 12 slants so that the device 10 may be attached to either a right or left hand. As illustrated in FIG. 1, the plate 36 is at an angle to the longitudinal axis of the device 10 and would be disposed at a substantially equal but opposite angle when the device is secured to a right hand. Positioning means 44, as shown in FIG. 1, coacts between the plate 36 and the hand member 12 for retaining the plate member 36 in one of the left or right-hand positions. The positioning means 44 preferably comprises a protrusion from either the plate 36 or the hand member 12 and a detent in the opposite member with the hand member 12 having two of either the protrusion or the detent. The protrusion or detent shown at 44 in FIG. 1 would engage the plate 36 when the plate 36 is moved to the position to accommodate a right hand.

The arm member, as alluded to above, is elongated and is arcuate in a direction transversely to its longitudinal axis. The arm member contains the slot 34 which extends therethrough adjacent one extremity. The means for attaching the arm member 14 to the arm comprises a second strap means 46. A first end of the strap means 46 is connected to the arm member 14 by coacting snap-together elements 42. similar to those previously described in regard to the strap means 40. The first end of the strap means is disposed adjacent the slot 34 and extends across the upper surface of the arm member 14 and away from the slot and around the opposite side of the arm member so as to go about the arm 15 and through the slot 34 and then back around the opposite side of the arm member 14 so as to go about the arm to a second end 48'.

Opposite ends of the first and second strap means 40 and 46 include coacting means for releasably connecting the ends of each strap means together. More specifically, the coacting means associated with each strap means comprises a pair of interengageable fastener strips including strips having a cloth-like base with a plurality of flexible loops extending therefrom and strips 52 having a cloth-like base with a plurality of flexible hooks extending therefrom and engageable With the loops on the strips '50. One of the strips 50 or 52 are attached at one end of the respective strap means and on one side thereof while the other of the strips 50 or 52 are attached to the other end of the strap means but on the opposite side thereof. Such hook and loop strips are well known in the art and are more specifically described in US. Pat. 3,009,235.

The pivot means 18 comprises a first washer 54 on the undersurface of the projection 28 of the arm member 14. Also included is a second washer 56 on the upper surface of the small portion 26 of the hand member 12. An organic polymeric washer 58 is disposed between the projection 28 and the small portion 26.
