Abstract

A hand exerciser includes a hollow sphere (10) composed of two halves (11, 12) and four openings (111, 121) are defined through the hollow sphere. A
frame (20) is fixedly received in the sphere and two handle disks (50) are rotatably connected to two opposite ends of the frame. Two massage disks (40) are rotatably connected to the other two opposite ends of the frame. The two handle disks and the two massage disks are rotatably engaged with the four openings of the sphere.
A
weight (60) is fixed to one of the two halves.

Description

~~Tf~Tf~~~E ~A~)D E~E~C~s~
The present invention relates to a hand exerciser that has a hollow sphere in which a weight is eccentrically connected. The sphere includes two handle disks and massage disks for hands to hold.
Conventional exercising devices are bulky and heavy, and include complicated structure which usually means a high cost. People usually cannot afford to buy different types of exercising devices and besides., there is no space for storage of these exercising devices. For those people work in offices, it is important to exercise their hand muscles because of operating computers for a long period of time.
Unfortunately, in the present market, no proper exercising device is provided for the exercise of hands.
The present invention intends to provide a hand exerciser that is in a shape of sphere and can be rotatably held by hand. A weight is eccentrieally installed in the sphere so that when rotating the sphere the muscles of hands can be exercised.
In accordance with one aspect of the present invention, there is provided a hand exerciser which comprises a hollow sphere composed of two halves each of which has four openings. A frame is fixedly received in the sphere and connected to the two halves. Two handle disks and two massage disks are respectively and rotatably connected to four ends of the frame, and are: rotatably engaged with the four openings of the sphere. A weight is fixed to one of the t~Jo halves.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings.

IN 'TIIE I)IZA~VINGS
Fig. 1 is an exploded view to show the hand exerciser of the present invention;
Fig. 2 is a perspective view to show the hand exerciser of the present invention;
Fig. 3 shows two hands holding the handle disks of the hand exerciser of the present invention;
Fig. 4 shows two palms pressing on the concave surfaces of the handle disks of the hand exerciser of th.e present invention;
Fig. 5 shows two hands pressing the massage disks of the hand exerciser of the present invention, and Fig. 6 is a cross sectional view to show the a~and exerciser of the present invention.
Referring to Figs. 1, 2 and 6, the hand exerciser of the present invention comprises a hollow sphere 10 which is composed of two halves 11, 12 and four openings 111, 121 are defined through an edge of the two halves 11, 12. Each of the halves 11, 12 has four connection tubes 112, 122 extending from an inner periphery thereof so that bolts 123 extend through the half 12, the connection tubes 122, and 112, and are engaged with nuts 113 which is received in holes 110 defined through the half 11.
A frame 20 is fixedly received in the sphere 10 by the bolts 123 which extend through four corners of the frame 20 when connecting the two halves 11, 12.
The frame 20 includes two pairs of opposite ends which are threaded ends 21.

Further referring to Fig. 4, two handle disks 50 each have a concave surface 501 and a hole 503 is defined through the concave surface 501. Each of the threaded ends 21 of the frame 20 is mounted with two bearings 22 and extends through the hole and engaged with a nut 504. A cap 505 is then mounted to the distal end of the each of the threaded ends 21 to cover the threaded ends 21. .~ handle 502 is connected to the handle disk 50 so as to define a space between the concave surface 501 and the handle 502. The two handle disks 50 are rotatable relative to the frame 20 and the sphere 10.
Two massage disks 40 are rotatably connected to the other two opposite threaded ends 21 of the frame 20. Two bearings 22 are mounted to each of the two threaded ends 21 which extend through a hole 402 in each of the massage disks and is engaged with a nut 403. A cap 404 is then mounted to the distal end of the each of the threaded ends 21 to cover the threaded ends 21. The massage disks each include a convex surface 401 and a plurality of bosses 405 extend from the convex surface 401. The two massage disks 40 are then rotatable relative to the frame 20 and the sphere 10. The two handle disks 50 and the two massage disks are rotatably engaged with the four openings 111, 112 of the sphere 10.
As shown in Fig. 3, the half 12 includes two tubes 123 extending from an inner periphery thereof and a weight 60 is fixed to the. two tubes 123 by bolts. The weight 60 makes the sphere 10 be easily rotated when rotating the sphere 10.
Referring to Figs. 3 and 4, the hands of the user may hold the handles 502 to rotate in opposite direction to exercise the waists. The palms may also to compress on the concave surfaces 501 to rotate the handle disks 50. Referring to Fig.

5, the two hands may also compress on the massage disks 40 to rotate the massage disks 40 in opposite directions.
