Elastic hand and digit exercise device
A hand and digit exercise device having a core section of elastic material surrounding and defining an open space, a plurality of elastic finger loops separate from and disposed about said core section and sized to receive digits of a hand and an elastic connection arm extending between each of said finger loops and said core section whereby said finger loops are attached to said core section at various location around the open space in the core section.
The invention broadly relates to devices for exercising hands and their digits (fingers).
People who use their hands for prolonged periods on repetitive tasks, such as operating computers, writing, etc., can develop repetitive stress injuries (RSI). A form of therapy that has been used to combat RSI comprises stretching a conventional thick rubber band between two or more fingers and repeatedly spreading the fingers against the tension of the rubber band. However, a rubber band is difficult to use because its simple loop provides limited options for exercises. A simple rubber band also tends to slip from its initial position when the digits are repeatedly spread apart.
BRIEF SUMMARY OF THE INVENTIONThe present invention comprises a finger exercise device having a core section of elastic material surrounding and defining an open space, a plurality of elastic finger loops separate from and disposed about the core section and sized to receive digits of a hand and an elastic connection arm extending between each of the finger loops and the core section whereby the finger loops are attached to the core section.
While described by its component parts, the present invention is most advantageously formed into a single unified piece of elastomeric material by a molding process, as is well known in the art.
The exercise device of the present invention permits a variety of different exercises to be performed using two or more digits of a hand whereby a multiplicity of hand and digit maladies can be addressed with a single device by repeatedly spreading apart the digits in the finger loops against the tension of the loops, arms and core. The core can be cylindrical in shape with a varying height wherein opposing ends of the core are wider than the intermediate portions for improved grip and comfort on inserted digits.
The foregoing and other embodiments, features and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
A plurality of elastic finger loops 14 are separate from and disposed about the core section 12 and sized to receive a digit of a hand. An elastic connection arm 16 extends between each finger loop 14 and core section 12 whereby the finger loops 14 are attached to the core section 12. In one embodiment, the connecting arms 16 have a generally rectangular cross-section (see
In its relaxed condition (no forces applied to it), core section 12 has a generally cylindrical shape with a generally circular cross-section.
As best illustrated in
The relaxed state of the finger loops 14 is generally elliptical, which permits the loops 14 to secure digits of varying sizes and, at the same time, prevent the loops 14 from sliding off of the initial position on the digits while exercises are being performed. The sections 14a of the loops 14 distal from the core section 12 are of greater height than the sections 14b closer to connecting arm 16, whereby digits inserted into the loops 14 have a comfortable location at which to apply pressure during exercises.
A pull tab 17 can be advantageously secured to the outboard end of each finger loop 14 to assist in placing the loop over a digit or removing it therefrom.
In the embodiment of
The configuration of finger loops about the core section 12 as described above provides a device which, when fit over the digits of one hand, exercises certain portions of the hand when the digits of the hand are separated against the tension of the various components of the device 11. A different spacing of the finger loops 14 about the core section 12 would provide a different exercise for a hand. A simple exercise for any two digits of a hand is provided by the core section 12 which is sufficiently elastic to permit two digits inserted in the space 13 to be separated against tension of the core section 12 and thereby perform an exercise function.
The amount of force required to conduct any exercise performed with the device 11 is a function of the elasticity of the materials used for each component, as well as the size of the core section 12. By adjusting these variables, those skilled in the art are able to provide a device 11 which best matches the needs of an individual hand and its malady.
Referring to
The core section 15 is a right cylinder of uniform height.
Referring to
The connecting arms 20 attaching each finger loop 23, 24, 27, 28 and 29 to core section 22 have a generally circular cross-section (see
Referring to
Referring to
By providing a core section having an internal open space, together with individual connecting arms between the finger loops and core section, as has been described in connection with each of the embodiments, the forces applied on these components, and thus on the digits being exercised, are more evenly distributed, producing a better exercise and reducing the failure rate of components of the device.
Of course, various changes, modifications and alterations in the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof. As such, it is intended that the present invention only be limited by the terms of the appended claims.
