Abstract
A swing machine includes a casing having a sliding member movably engaged with a rail and the sliding member is driven by a block eccentrically connected to an output shaft of a motor. A support member is connected to a top of the sliding member. A first protrusion extends from a side of the sliding member and a limitation member located in the casing has a wave-shaped slot in which the second protrusion is movably engaged.
Description
FIELD OF THE INVENTION
The present invention relates to a swing machine having a wave-shaped slot such that the support member moves in various directions.
BACKGROUND OF THE INVENTION
A conventional swing machine is shown in FIG.
7
and includes a motor
71
whose output shaft
711
is eccentrically connected to a block
72
. A sliding member
73
is movably engaged with two rods
74
and the block
72
has a protrusion
722
which is engaged with the sliding member
73
. A support member
75
is connected to the sliding member
73
so that when the motor
71
is in operation, the block
72
drives the sliding member
73
to move in a horizontal direction. A use may put his/her feet on the support member
75
and the muscles of the feet can be relaxed by the swing of the support member
75
. However, the way of swing does not change and is boring for the users so that the market expects new generation of the swing machine that may generate various ways of swing to effectively relax the muscles of the feet of users.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a swing machine which comprises a casing having a motor received therein. A block is eccentrically connected to an output shaft of the motor and a first protrusion extends from a side of the block. A rail is located in the casing and has a groove. A sliding member is slidably engaged with the groove and has a slot in which the first protrusion of the block is movably engaged. A second protrusion extends from a side of the sliding member and a top of the sliding member is connected to a support member. A limitation member is located in the casing and has a wave-shaped slot in which the second protrusion is movably engaged.
The primary object of the present invention is to provide a swing machine wherein the support member is moved in various ways and directions.
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
FIG. 1
is a perspective view to show the swing machine of the present invention;
FIG. 2
is an exploded view to show the rail, the sliding member and the limitation member of the swing machine of the present invention;
FIG. 3
is a side view to show the swing machine of the present invention;
FIGS. 4
to
6
show the three positions of the second protrusion in the wave-shaped slot, and
FIG. 7
shows a side view of a conventional swing machine.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1
to
4
, the swing machine of the present invention comprises a casing and a motor
1
is received in the casing. A block
2
is eccentrically connected to an output shaft
11
of the motor
1
and a first protrusion
22
extends from a side of the block
2
.
Two posts
6
are located in the casing and a rail
4
is mounted between the two posts
6
by mounting two rings
41
on two ends of the rail
4
to the two posts
6
. A groove
42
is defined in the rail
4
. A sliding member
3
has a flange
31
extending from a lower end of the sliding member
3
and the flange
31
is slidably engaged with the groove
42
in the rail
4
. A support member
34
is connected to a top of the sliding member
3
and includes two recesses
341
so that two feet of the users can be put in the two recesses
341
. A slot
32
is defined in a side of the sliding member
3
so that the first protrusion
22
of the block
2
is movably engaged. A second protrusion
33
extends from the other side of the sliding member
3
.
A limitation member
5
has two rings
51
mounted to the two posts
6
and has a slot which includes a section of wave-shaped slot
52
. The second protrusion
33
is movably engaged in the slot in the limitation
5
.
As shown in
FIGS. 4
to
6
, when the motor
1
is rotated, the block
2
drives the sliding member
3
moves in a horizontal direction as performed by the conventional swing machine. When the second protrusion
33
enters in the wave-shaped slot
52
, the sliding member
3
generates an up-and-sown movement and when the second protrusion
33
leaves from the wave-shaped slot
52
the support member
34
moves in horizontal direction. By the limitation member
5
, the support member
34
may move in different ways and directions.
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 swing machine comprising:a casing having a motor with a block eccentrically connected to an output shaft of the motor, a first protrusion extending from a side of the block; a rail located in the casing and having a groove defined therein, a sliding member slidably engaged with the groove and having a slot in which the first protrusion of the block is movably engaged, a second protrusion extending from a side of the sliding member and a top of the sliding member connected to a support member, and a limitation member located in the casing and having a wave-shaped slot in which the second protrusion is movably engaged.
- 2. The swing machine as claimed in claim 1 further comprising two posts located in the casing and the rail and the limitation member each having two rings on two ends thereof so as to be mounted to the two posts.
- 3. The swing machine as claimed in claim 1 further comprising a flange extending from a lower end of the sliding member and the flange slidably engaged with the groove in the rail.
