BACKGROUND OF THE INVENTION
(a)Field of the Invention
The invention relates to a cord storage device for mouse, and more
particularly, to a cord storage device capable of collecting and releasing a
cord of a mouse as well as forming an integral with the mouse body
thereof.
(b) Description of the Prior Art
Referring to the inventor's prior invention disclosed in the US Patent
No. 6434,24981. Earphone wire Winding Box with Coaxial and Dual
Wheels, the invention overcomes the problem of poor contact between
conductive terminal of circuits and circuit structure of an electric appliance
as described in the aforesaid invention. Two turning wheels, one large
and one small, are provided in the inventor's prior invention, wherein a
signal wire is stored on wheel breadths of the large and small turning
wheels, through which one conductive terminal of the signal wire is kept
fixed, so that sliding movements are not required for electrically
connecting a conductive element thereof with circuit elements at an
interior of the electric appliance.
The inventor's prior invention is indeed quite useful; however, to further
-1-

implement the invention in various other applications, the technique using
coaxial and dual wheels shall be put to use in mouse structures.
SUMMARY OF THE INVENTION
Therefore, the primary object of the invention is to provide a cord
storage device for mouse, wherein a plurality of wheels having different or
equal diameters are utilized for storing a mouse cord at wheel breadths
thereof, as well as being capable of winding and releasing the mouse
cord.
Another object of the invention is to provide a cord storage device for
mouse, wherein large and small turning wheels thereof and an axis portion
thereof are disposed at an interior of an independent base thereof, so as
to wind or release the mouse cord into or out of the base. In addition, a
surface of the base also provides placement of the mouse in order to be
readily portable.
The other object of the invention is to provide a cord storage device for
mouse, wherein two turning wheels having different diameters, and an
axis portion thereof are disposed in an accommodating room of the mouse
body, so as to collected or release the cord into or out of the mouse body.

7.
According to the aforesaid primary characteristics, wherein a side wall

4.
According to the aforesaid primary and secondary characteristics,
excellences of the invention shall be described in the following examples.
EXAMPLES
1. Referring to FIG. 5 and 6, the large and small turning wheels are both
flexibly connected to the same axis portion 30, and hence the small
turning wheel 20 also rotates one revolution when the large turning wheel
10 turns one revolution. For one revolution made by the large turning
wheel 10, the outer cord 522 being released from (or winded into) the
large storage wheel 15 equals to ~ x D, where D is the diameter of the
large turning wheel 10; similarly, for one revolution made by the small
turning wheel 20, the inner cord 521 released from (or winded into) the
small storage groove 25 equals to ~ x d, where d is the diameter of the
small turning wheel 20. As a result, when the large and small turning
CA 02434817 2003-07-09
wheels 10 and 20 rotate using a same axis, the ratio of lengths of cord
released (or winded) equals to the ratio of diameters of the large and small
turning wheels 10 and 20; that is, D: d. In a preferred embodiment of the
invention, the ratio of diameters of the large and small turning wheels 10
and 20 is 6: 1. Suppose the outer cord 522 is released when the mouse
body 50 is pulled out by a user, the inner cord 521 having an attached plug
55 is released along as well. Provided that the outer cord 522 being
released is 50cm for the usage of the mouse body 50, the inner cord 521
released from the small storage groove 25 via the guiding orifice 44 is
8.3cm, so that the plug 55 connected to the outer end of the inner cord
521 may be plugged to a power connector port of an electric appliance 90
as shown in FIGS. 10 and 11. Therefore, when the mouse body 50 is
pulled out and displaced, excessive displacement between the plug 55
and the base 40 is not incurred. During cord winding, the spring 80
imposes a contraction effect on the large and small turning wheels 10 and
20, and thus the inner and outer cords 521 and 522 are winded back into
the large and small storage grooves 15 and 25. Wherein, a rear end of
the plug 55 is stopped at the stop portion 431 that provides a positioning
effect when the plug 55 is being restored back into the base 40 as shown
in FIGS.S and 7.
_8_
CA 02434817 2003-07-09
2. Referring to FIGS. 2 and 3, inner sides of arched edges 45 are
provided with slanting flanges 451 for the mouse body 50 to fasten to a
surface 401 in a downward direction. A periphery 51 of the mouse body
50 is butted against the flanges 451 such that the arched edges 45 are
deformed outwardly with elasticity, thereby effectively mounting and
positioning the mouse body 50 onto the surface 401 and combining the
mouse body 50 with the base 40 into one body for easy storage and
carrying. To use the structure, only the mouse body 50 needs to be
pulled out from the base 40 in an upward direction, then forces imposed
by the flanges 451 are disappeared and the arched edges 45 are
elastically repositioned.
3. Referring to FIG. 8 showing another embodiment according to the
invention, the large and small turning wheels 10 and 20 are disposed in
the accommodating room 42 located at the interior of the mouse body 50,
and thus the independent base 40 may be eliminated in this embodiment.
When the outer cord 522 is released, the large and small turning wheels
10 and 20 rotate coaxially regarding the axis portion 30 as a rotation axis
thereof. At this point, the ratio of the diameters of the large and small
turning wheels 10 and 20 may be increased (10: 1, for example); the
larger the ratio is, the shorter the length of the inner cord 521 released
_g_
CA 02434817 2003-07-09
becomes, and therefore the length of the inner cord 521 is extremely short.
Also, the conductive terminal 57 of the inner cord 521 may be a fixed
connector port, and the inner cord 521 is in a lax state in the small storage
groove 25 during cord releasing without making a mess in the
accommodating room 42 (as shown in F1G. 9).
4. Referring to FIG. 7 the large and small turning wheels 10 and 20 may
also be designed as having same diameters (1: 1 ) for adapting to various
operating environments or special requirements, and hence the lengths of
the inner and outer cords 521 and 522 are equal to each other when being
released. FIG. 10 shows a planar view illustrating the inner cord 42 in the
base 40 being connected to a power socket of the electric appliance 90.
Referring to FIG. 11, when the mouse body 50 according to the invention
is pulled out, the length of the outer cord 522 drawn from the base 40 is
comparatively large and the inner cord 521 drawn is extremely small.
Referring to FIG. 4, the invention may also provide at least one USB
connector port 49 at one side of the base 40 for plugging a USB plug 491
when necessary.
It is of course to be understood that the embodiment described herein is
merely illustrative of the principles of the invention and that a wide variety
of modifications thereto may be effected by persons skilled in the art
-10-

without departing from the spirit and scope of the invention as set forth in
the following claims.
