Hand exercisers
A hand exerciser includes a loop having a smooth outer periphery and a plurality of rings each having a hole so that the loop extends through the hole of each ring. An inner diameter of the hole of each ring is 1.5 times of an outer diameter of the loop so that the rings are rotatable relative to the loop. The user rotates the loop to keep the rotating rings maintained at a section and the vibration of the rings to the loop exercises the hand holding the loop.
The present invention relates to a hand exerciser having a loop with a plurality of rings rotatably mounted to the loop. The rings are rotated relative to the loop and are maintained at a position by rotating the loop.
BACKGROUND OF THE INVENTION A conventional hand exerciser is shown in
The present invention intends to provide a hand exerciser that the user has to rotate the loop and requires skill to keep the rings on their positions on the loop.
SUMMARY OF THE INVENTIONIn accordance with one aspect of the present invention, there is provided a hand exerciser which comprises a loop having a smooth outer periphery and extending through a hole in each of rings which are rotatable relative to the loop.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
As shown in
When the user rotates the loop 20, there is a frictional force “C” between the rings 30 and the loop 20 and the direction of the frictional force “C” is shown in
As shown in
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
Claims
1. A hand exerciser comprising:
- a loop having cross sections including a smooth outer periphery and an outer diameter; and
- a plurality of rings each having a hole defined therethrough, with the hole having an inner diameter generally equal to 1.5 times of the outer diameter of the cross sections of the loop, with the loop extending through the hole of each ring so that the rings are rotatable relative to the loop, with the hole of each ring contacting with the loon so as to shake or vibrate the loop and therefore exercising the hands holding the loop.
2 (canceled).
3. The hand exerciser as claimed in claim 1, wherein the plurality of rings each includes an outer periphery, wherein the hole through each of the rings is eccentrically defined relative to the outer periphery of the ring.
4. The hand exerciser as claimed in claim 1, wherein at least one of the rings has a polygonal outer periphery.
5. The hand exerciser as claimed in claim 3, wherein at least one of the rings has a polygonal outer periphery.
6. A hand exerciser comprising:
- a loop having cross sections including a smooth outer periphery; and
- a plurality of rings each having a hole defined therethrough, with the loop extending through the hole of each ring so that the rings are rotatable relative to the loop, wherein the plurality of rings each includes an outer periphery, wherein the hole through each of the rings is eccentrically defined relative to the outer periphery of the ring.
7. The hand exerciser as claimed in claim 6, wherein at least one of the rings has a polygonal outer periphery.
8. A hand exerciser comprising:
- a loop having cross sections including a smooth outer periphery, and
- a plurality of rings each having a hole defined therethrough, with the loop extending through the hole of each ring so that the rings are rotatable relative to the loop, wherein at least one of the rings has a polygonal outer periphery.
