Abstract
A move-in-company style joy stick comprising in a knob thereof a space of suitable size formed by a partition plate, a ball added with a weight, a horizontal grating and a vertical grating are placed in the space. The horizontal and vertical gratings are provided each with a coaxial roller respectively contact the ball in rotation at a position slightly lower than a horizontal central line of the ball. A supporting wheel is provided at a position having an equal angular distance to both the coaxial rollers. When the knob of the joy stick is shaken, a vertical central line of the ball added with the weight is always kept in its vertical position, hence the coaxial rollers are rubbed by the ball in rotation. In this way, the required amount of displacement of the horizontal and vertical gratings being shaken is obtained.
Description
BACKGROUND OF THE INVENTION
1. Field of the invention
The present invention is related to a move-in-company style joy stick, and especially to a move-in-company style joy stick of which internal elements move in company therewith and thereby amount of displacement in operation can be detected. In this way, the whole joy stick can get rid of limitation of the bottom receiving-seat.
2. Description of the Prior Art
A conventional joy stick used for a computer or a television game device mostly is provided at the central position of a bottom receiving-seat. By shaking of the joy stick, internal gratings in the bottom receiving-seat move relatively, in this way, the required amount of displacement in operation can be obtained. However, the joy stick must be combined in operation with the bottom receiving-seat, this makes much inconvenience. In order to make clear of the structure and functions of the conventional joy stick,
FIG. 1
is taken as a reference for explanation:
A conventional joy stick has a control rod
10
with a suitable length for holding by a user, the control rod
10
is provided near the central position of a bottom receiving-seat
11
. The bottom receiving-seat
11
is provided internally thereof with a horizontal grating
12
and a vertical grating
13
connected operationally with the control rod
10
. The horizontal grating
12
and the vertical grating
13
are mounted respectively in a detecting device
14
and a detecting device
15
. When the user moves the control rod
10
, the end
16
of the control rod
10
moves synchronically the gratings
12
and
13
, the detecting devices
14
,
15
can thereby detect the required amount of displacement in operation. And the joy stick can get the control function.
The main defect of such a conventional joy stick is that the control rod
10
for moving must be connected to the bottom receiving-seat
11
with a specified size. In order to prevent from instability induced by shaking and moving of the whole joy stick when force is applied in using, the bottom receiving-seat
11
must have quite a large bottom area. This makes the necessity of a larger volume of the bottom receiving-seat
11
. And if the user wants to control the joy stick at a farther distance or in a more comfortable posture, the control rod
10
shall be moved together with the bottom receiving-seat
11
as a whole, inconvenience results in such operation.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a move-in-company style joy stick, wherein, the knob of the move-in-company style joy stick is provided internally with a ball with a suitable size. The ball is added with a weight at the lower portion thereof. A horizontal grating and a vertical grating are provided therein and are provided respectively with a coaxial roller; these rollers contact the ball at the levels slightly lower than the horizontal central line of the ball. The ball with the added weight rubs the rollers in rotation when the joy stick is moved, thereby, the required amount of displacement in operation can be obtained. In this way, the whole joy stick itself is able of detect the required amount of displacement thereof. It can therefore operate independently and is out of limitation of requiring a bottom receiving-seat of large volume.
The present invention will be apparent in the novelty and other features thereof after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIG. 2
, a hollow knob
20
of the joy stick of the present invention is provided therein with a space of suitable size formed by a partition plate
21
for mounting therein a ball
30
added with a weight, and for mounting therein a horizontal grating
40
, a vertical grating
50
, a supporting wheel
60
and a releasing-proof device
70
.
Referring together to
FIGS. 3 and 4
, the horizontal grating
40
and the vertical grating
50
are provided with a coaxial roller
41
and a coaxial roller
51
respectively contacting the ball
30
. The ball
30
shown in
FIG. 3
is drawn with a horizontal central line
300
, while a horizontal central line c of the coaxial roller
41
and of the coaxial roller
51
is preferably at the position a distance “a” slightly lower than the horizontal central line
300
. The supporting wheel
60
is preferably provided at a position having an equal angular distance to both the coaxial roller
41
and the coaxial roller
51
, and is also on the horizontal central line c of the coaxial roller
41
and the coaxial roller
51
. A support
42
and a support
52
respectively of the coaxial roller
41
and the coaxial roller
51
as well as a support
62
of the supporting wheel
60
are all provided on the partition plate
21
.
As shown in
FIG. 3
,
5
, in the preferred embodiment of the present invention depicted therein, the ball
30
added with a weight is provided near the bottom thereof with a central through hole
31
. Above a bottom surface
33
of the central through hole
31
, there is the weight
35
of which the position is preferably lower than the horizontal central line c.
Referring together to
FIG. 2
,
6
and
7
, with the above stated structure of joy stick, no matter how the knob
20
of the joy stick moves, the ball
30
provided therein added with the weight
35
has a vertical central line
303
thereof always kept in its vertical position. While the coaxial roller
41
and the coaxial roller
51
displace in pursuance of moving of the knob
20
of the joy stick and are rubbed by the ball
30
in rotation. In this way, the horizontal grating
40
and the vertical grating
50
both are shaken to obtain the required amount of displacement. Thereby, moving or shaking of the joy stick can allow detection of the amount of displacement.
In order to get larger stability in operation of the whole joy stick, the central through hole
31
of the ball
30
is provided on the top thereof with a filler block
37
which is pressed by the releasing-proof device
70
. In cooperation with this filler block
37
, the releasing-proof device
70
is provided on the top of and integrally with the knob
20
of the joy stick with a cylinder
71
which has a spring
72
therein. An exposed small ball
73
is provided in front of the spring
72
for pressing the filler block
37
.
By the fact that the present invention can obtain the required amount of displacement during movement of itself, the joy stick needs only a very small bottom receiving-seat for electric connection. There is no more requirement of a bottom receiving-seat with a large volume; this can largely reduce the volume in manufacturing as well as in packaging. Besides, without limitation of requiring a bottom receiving-seat with a large volume, a user can operate the joy stick in any comfortable posture.
