Description
- This application claims priority to U.S. Provisional Patent Application No. 61/614,732, filed on Mar. 23, 2012, which is incorporated herein in its entirety.
- A conventional hand grasping apparatus (e.g., a hand exercising device) can include an element (e.g., a handle) that can be pulled by fingers. Typically, the finger handle has a fixed surface and thus does not roll/rotate. That is, the contact surface between the finger handle and the fingers remains static. When a user grabs the handle using his/her fingers and closes their hand, the fingers naturally tend to curl and a friction force (e.g., the horizontal Ff as illustrated in
FIG. 1 ) can occur between the finger handle and the inner surface of the fingers. For example,FIG. 1 demonstrates a horizontal friction force Ff between the fingers and the finger handle when the hand closes. The friction force can cause discomfort and even pain to a user's metacarpophylangeal (MCP) joint and wrist since it may force the user to rotate his wrist as well as the MCP joint while curling his fingers. The discomfort and pain can aggravate when the finger curling motion is repeated and/or when a heavy load is carried. - In accordance with the disclosed subject matter, devices are described for apparatuses with rolling contact handles.

It will be apparent to one skilled in the art, however, that the disclosed subject matter may be practiced without such specific details, and that certain features, which are well known in the art, are not described in detail in order to avoid complication of the disclosed subject matter. In addition, it will be understood that the embodiments described below are only examples, and that it is contemplated that there are other systems and methods that are within the scope of the disclosed subject matter.
- Embodiments of the disclosed subject matter can provide features for a more comfortable apparatus for hand exercising, such as grip strength training for users with unimpaired hand function or as a tool during the course of physical therapy for user with impaired hand function. An apparatus for hand exercising can have a rolling contact handle which rolls along the inside surface of the fingers. The rolling contact handle can eliminate or reduce the shear friction force between a user's fingers and a finger handle.
FIG. 2 illustrates a finger curling situation when the finger handle (or its surface) rolls or rotates. Unlike in the situation illustrated inFIG. 1 , the horizontal friction force between the finger handle and the fingers is largely eliminated when the finger handle rotates/rolls as the fingers curl. The elimination of the horizontal friction force can alleviate the force against the MCP joint and the wrist and allow the fingers to curl naturally and freely towards the palm, making hand closing motions more comfortable. This type of grasp can sometimes be referred to as a “Rolling Contact” grasp in hand biomechanics, similarly to the interaction when turning a nut onto a screw. The Rolling Contact (RC) Handle can allow the user to exert higher forces when exercise grasping in a safer and more comfortable manner. As described in details later in this document, embodiments of the disclosed subject matter can also provide features for a more effective apparatus for hand exercising. An apparatus for hand exercising can have a rolling contact handle which can provide individual support for each individual finger. The individualized finger support can allow exercising or motion of individual fingers. The apparatus for hand exercising can also allow customization of the individual finger support to meet various exercising needs and goals. -
