DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A jogging machine having a jogging platform adjustable and foldable structure comprises a base
1
, a jogging platform
2
, a wheel base
3
, a linear actuating device
4
and two pumps
5
.
The base
1
is laid flat on the floor and comprises a pair of side supports
11
to support a panel
12
on the top thereof. One of the side supports
11
has a hole
111
, and the lower portion of the base
1
is provided with a pair of rails
13
.
The jogging platform
2
has a motor
21
, a pulley
22
, and a plurality of ribs
23
crossly secured to the bottom thereof. Two L-shaped arms
24
are secured to the front end of the jogging platform
2
with one end
241
of each arm
24
pivoted to the jogging platform
2
and the other end
242
pivoted to the base
1
to connect the base
1
and the jogging platform
2
together. A stopper
25
is formed on one side of the jogging platform
2
, which has a spring
251
at the inward. When the jogging platform
2
is in a standing position, the stopper
25
will be located in the hole
111
of the side support
11
of the base
1
. The other end of the jogging platform
2
is provided with a pair of rollers
26
thereat. A pair of pins
271
is formed on the two sides of the jogging platform
2
above the arms
24
.
The wheel base
3
is located underneath the jogging platform
2
, and has one end
31
pivoted to the jogging platform
2
while the other end is provided with a pair of wheels
32
sliding onto the rails
13
of the base
1
, and further comprises a pair of lugs
33
at a center rod thereof.
The linear actuating device
4
is a spiral elevating device being secured to one of the ribs
23
of the jogging platform
2
and is activated by a motor
41
to spin a bolt
43
to move in and out within a tube
42
in a threaded manner. The tube
42
has one end pivoted to the lugs
33
of the wheel base
3
by means of a fastener
6
composed of a bolt
61
and a nut
62
to pull and push the wheel base
3
along the rails
13
of the base
1
.
The pumps
5
are secured on respective sides of the jogging platform
2
. Each pump
5
has a strut
51
with one end of the strut
51
secured to the bottom of the jogging platform
2
by means of a fastener
6
A composed of a bolt
61
A and a nut
62
A while the other end of the pump
5
is pivoted on the base
1
.
To assemble the present invention, the base
1
is placed on the ground, as shown in
FIGS. 2 and 3
, the front end of the jogging platform
2
is seated on the base
1
and pivoted with the front ends
241
of the two arms
24
to the base
1
. The rear end of the jogging platform
2
is supported by the rollers
26
on the ground. The wheel base
3
is also secured to the bottom of the jogging platform
2
close to the ends
241
of the arms
24
. The pins
27
, at this moment, are seated above the arms
24
, which also keep the jogging platform
2
at place when in a folding status. The linear actuating device
4
has the tube
42
pivoted to the lugs
33
at the center section of the wheel base
3
.
When the jogging platform
2
is lifted upward, as shown in
FIG. 4
, the linear actuating device
4
will pull the tube
42
reward, which links the wheels
32
of the wheel base
3
to slide along the rails
13
and the wheel base
3
moves upward, subsequently to support the jogging platform
2
, and whereas the rollers
26
will roll the jogging platform
2
to assist the upward movement of the jogging platform
2
. The upward movement pivots the jogging platform
2
and the ends
241
of the arms
24
with respect to the ends
242
of the arms
24
, which assists to lift up the jogging platform
2
. Upon the jogging platform
2
has reached to the position, the wheels
32
and the ends
242
of the arms
24
support the front end of the jogging platform
2
while the rollers
26
support the rear end of the jogging platform
2
. This design can hold the jogging platform
2
steady and can undertake more weight in a steady manner.
When the jogging platform
2
is collapsed vertically, as shown in
FIGS. 5 and 6
, the tube
42
of the linear actuating device
4
will stretch to its maximum length, thus the jogging platform
2
maintains a parallel position with respect to the base
1
. The strut
51
of each pump
5
will also stretch to its maximum length, at this moment, wherein the arms
24
also change to an upright position. The stopper
25
of the jogging platform
2
will be urged by the spring
251
to insert into the hole
111
of the base
1
, which also keeps the jogging platform
2
in an upright position.
To lay the jogging platform
2
flat, simply pull the stopper
25
to detach from the hole
111
, and the jogging platform
2
is free to put down, whereas the strut
51
of the pump
5
buffers the jogging platform
2
to lay in a slow movement.
