GRIPPING DEVICE

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 60/475,622 filed on June 4, 2003 which is incorporated herein by reference.

TECHNICAL FIELD

The present invention relates generally to a gripping device that removably binds onto a user's wrist and that is especially adapted to enable the user to grip onto an exercise device.

BACKGROUND OF THE INVENTION

It has long been known that for individuals who have limited mobility of their limbs, regular exercise can provide significant benefits. Such individuals, who may have suffered a spinal injury, stroke, multiple sclerosis (MS), muscular dystrophy (MD), or other similar injury or disorder that impairs mobility (either temporarily or permanently), may also find that their impairments can even present significant obstacles to exercising other relatively unaffected body parts.

Regular movement of all major body parts has been shown to be necessary to promote the comfort, health and general well-being of individuals suffering from such disabilities. A failure to do so can have painful, even unhealthful and dangerous consequences. For example, immobility tends to lead rapidly to stiffened and painful joints and tendons. In the longer term, atrophy of unused and underused muscles can occur. A greater susceptibility to the formation of blood clots has been demonstrated. Long-term immobility also leads to an overall deterioration of the cardiovascular system.

Docket No. RKE-107PCT 1 By way of contrast, when impaired limbs are regularly exercised (e.g., when subjected to repeated manual extensions by a physical therapist), joints tend to become more flexible, circulation is improved, the tendency to atrophy is reduced, the heart tends to work more efficiently, and the patient tends to experience less pain and discomfort. While the benefit of such exercise is indisputable, it can require considerable time and effort of both the afflicted individual and the assistant (therapist or volunteer).

The problem is that many types of exercise equipment require a user to hold onto the handles of the machine. For users that have an injury or disorder that impairs mobility (either temporarily or permanently) of their hands, they often can't hold onto the handles, and thus their impairment can present a significant obstacle to exercising.

SUMMARY OF THE INVENTION

According to the present invention, a gripping device that removably attaches onto a user's wrist to enable the user to grip onto a handle, comprises a wrist-wrapping, elongated belt portion having opposite ends and a gripping structure that extends outward from the plane of the belt portion.

Also according to the present invention, the elongated belt portion is generally formed from a flexible strip of material. The flexible strip of material is selected from a material selected from the group comprising leather, plastic or cloth. Further, according to the present invention, the gripping structure has a lower section, an upper section and a free end section. The gripping structure has a lower section encased in the belt portion.

Still further, according to the present invention, the upper end section has a centerline Ca-La disposed at an angle a of between 2 and 30 degrees with respect to a centerline C-L extending through the lower end section of the gripping structure.

Docket No. RKE-107PCT 2 Yet further, according to the present invention, the gripping structure is stiff and relatively rigid. The gripping structure component is formed of a material selected from the group comprising metal and plastic and can be adjusted to change the curvature between the upper section and the lower section.

Also according to the present invention, the free end section of the gripping device curves from and is of a unitary construction with upper section and has an end that generally extends in a direction towards the belt portion.

Still further, according to the present invention, the lower section is disposed or encased within the flexible strip of material forming the gripping device.

According to the present invention, there is disclosed a method of removably attaching a gripping device to a user's wrist to enable the user to grip onto a handle. The method comprises the steps of: providing a gripping structure having a wrist-wrapping, elongated belt portion with opposite ends and a gripping structure including a lower section, an upper section and a partially curved end section that extends outward from the plane of the belt portion; and placing the user's hand so that the one side of the belt portion of the gripping device rests against the user's wrist and the user's hand extends over the curved end portion.

Also according to the present invention, the method includes the steps of: wrapping a first end of the elongated belt portion around the back of the wrist of the user so that a first strip connecting gripping material is disposed directly on the back of the user's wrist opposite the palm of the hand; and wrapping a second opposite end of the elongated belt portion so that a second strip of connecting material overlaps the first strip and they are locked together.

Docket No. RKE-107PCT BRIEF DESCRIPTION OF THE DRAWINGS

Reference will be made in detail to preferred embodiments of the invention, examples of which may be illustrated in the accompanying drawing figures. The figures are intended to be illustrative, not limiting. Although the invention is generally described in the context of these preferred embodiments, it should be understood that it is not intended to limit the spirit and scope of the invention to these particular embodiments.

Certain elements in selected ones of the figures may be illustrated not-to- scale, for illustrative clarity. The cross-sectional views, if any, presented herein may be in the form of "slices", or "near-sighted" cross-sectional views, omitting certain background lines which would otherwise be visible in a true cross-sectional view, for illustrative clarity.

The structure, operation, and advantages of the present preferred embodiment of the invention will become further apparent upon consideration of the following description taken in conjunction with the accompanying figures, wherein:

Figure 1 is a top view of the gripping device of the present invention;

Figure 2 is a bottom view of the gripping device of the present invention;

Figure 3 is a side view of the gripping device of the present invention; and

Figure 4 is a three-dimensional view of the gripping device partially attached to the wrist of a user.

DETAILED DESCRIPTION OF THE INVENTION Referring to Figure 1, there is shown a top view of the gripping device 10. The gripping device 10 includes a wrist-wrapping, elongated belt portion 12 having opposite ends 14, 16, and a gripping structure 18

Docket No. RKE-107PCT 4 that extends outward, as shown in Figures 1 and 2, from the plane of the belt portion 12. The belt portion 12 is generally formed from two strips of flexible strip of material, such as for example, leather, plastic or cloth. The gripping structure 18 has a lower section 18a, an upper section 18b and a free end section 18c. The lower end section 18a can be encased between the two strips of material forming the belt portion 12.

As shown in Figure 3, the upper end section 18b has a centerline Ca-La disposed at an angle a of between about 2 degrees and 30 degrees and preferably about 15 degrees and 25 degrees with respect to the centerline C-L extending through the lower end section 18a of gripping structure 18. Typically, the gripping structure or component 18 is stiff and relatively rigid. The upper section 18b projects upward from belt portion 12 and has a free end section 18c that curves and is of a unitary construction with upper section 18b. The free end section 18c has a tip 24 that points in a direction towards the elongated belt portion 12 of the gripping device 10. While the curvature of the gripping component forms a generally semi-circular shape, the shape could be more or less semicircular depending on the preference of the user or the shape of the handle to which it is engaged. Typically, the gripping component 18 is constructed of a metal insert disposed or encased within the two strips of flexible material of the gripping device 10. When the gripping structure 18 is formed of a metal insert, it can be adjusted to change the curvature between the upper section 18b and the lower end section 18a or the angle between the free end 18c and the upper section 18b to accommodate different shaped or sized hands or different shaped or sized exercise handles. Typically, the radius of curvature r is approximately V inch to 1 inch and preferably about % of an inch. While the gripping component 18 can be formed with a metal insert, it is also within the terms of the invention to form it of a rigid material such as plastic, and either cover it or allow it to protrude outward from the belt portion 12 of the gripping device 10.

Docket No. RKE-107PCT 5 Referring again back to Figure 1, which shows one side 27 of the gripping device 10, there are disposed two strips 25 and 26 of a gripping material, such as for example Velcro-type gripping material. On the opposite side 29 of the gripping device 10, as shown in Figure 2, there are two additional strips 28, 30 of Velcro-type gripping material.

To attach the gripping device 10 onto a person's hand 30, as shown in Figure 4, first the person places their hand so that the one side 27 of the belt portion 12 of the gripping device 10 rests against the user's wrist and the hand 31 extends over the curved end portion 18c of the gripping device. Then, the end 16 of the elongated belt portion 12 is wrapped around the back of the wrist of the user so that the strip 28 of connecting gripping material is disposed directly on the back of the user's wrist opposite the palm of the hand. Next, the other end 14 of the elongated belt portion 12 is wrapped so that the strip 25 of connecting gripping material overlaps the strip 28 of connecting material and they are locked together. To more firmly secure the gripping device 10 to the wrist, the rest of the of the elongated belt portion 12 is wrapped around the portion of the gripping device 10 that is already secured to the user's wrist so that the strip 26 of gripping material overlies and is removably affixed to the strip 30 of gripping material.

In use, a person with a hand that is very stiff or immobile can attach gripping device 10 onto the handle of a machine such as exercise devices and thereby be able to operate the machines.

Although the invention has been shown and described with respect to a certain preferred embodiment or embodiments, certain equivalent alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification and the annexed drawings. In particular regard to the various functions performed by the above described components, the terms (including a reference to a "means") used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the

Docket No. RKE-107PCT 6 specified function of the described component (i.e., that is functionally equivalent), even though not structurally equivalent to the disclosed structure which performs the function in the herein illustrated exemplary embodiments of the invention. In addition, while a particular feature of the invention may have been disclosed with respect to only one of several embodiments, such feature may be combined with one or more features of the other embodiments as may be desired and advantageous for any given or particular application.
