A gardening working vehicle structure including a vehicle frame, two wheels, and a seat frame. The vehicle frame is provided with two wheels to move the vehicle frame horizontally. The vehicle frame has a seat tube extending outward. A retractable rod is adjustably mounted in the seat tube and has an annular stop flange to support a seat frame which has a horizontal support portion, and a vertical backrest portion. The support portion is provided with a mounting tube which is rested on the stop flange of the retractable rod, so that the seat frame may be rotated on the retractable rod freely.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a gardening working vehicle structure, and more particularly to a gardening working vehicle structure having a seat frame whose height may be adjusted so as to fit users of different statures, thereby enhancing the versatility of the gardening working vehicle structure.
2. Description of the Related Art
Usually, a gardener may be seated on a chair, a stool or the like to proceed the gardening work during a long period of time. However, the height of the stool is fixed and cannot be adjusted, so that the stool cannot fit users of different statures, thereby causing inconvenience to users of larger statures. In addition, when the user wishes to move to another position in the garden, he has to stand up and move the stool to the destined position, thereby causing inconvenience to the user. Further, the user may put on a sunshade cap whose sunshade effect is very poor, so that the user easily feels uncomfortable when working under the sunshine.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a gardening working vehicle structure having a seat frame whose height may be adjusted so as to fit users of different statures, thereby enhancing the versatility of the gardening working vehicle structure.
Another objective of the present invention is to provide a gardening working vehicle structure having a seat frame that may be rotated on the retractable rod freely, so that the user may turn around freely to take his tool or article, thereby greatly increasing convenience of work.
A further objective of the present invention is to provide a gardening working vehicle structure having a seat frame that may be provided with a support tube so that a support rod of a sunshade umbrella may be inserted into the support tube of the seat frame, thereby providing a sunshade effect to the user during work.
In accordance with the present invention, there is provided a gardening working vehicle structure, comprising a vehicle frame, two wheels, and a seat frame, wherein:
the vehicle frame has two ends each respectively provided with a wheel that may be rotated to move the vehicle frame horizontally, the vehicle frame has a top face provided with a seat tube extending outward, a retractable rod is adjustably mounted in the seat tube of the vehicle frame, a quick release set is mounted on an outer periphery of a top portion of the seat tube of the vehicle frame for clamping and releasing the retractable rod, the retractable rod is formed with an annular stop flange for supporting a seat frame;
the seat frame is mounted on the retractable rod, and has a first section formed with a horizontal support portion, and a second section formed with a vertical backrest portion, the support portion of the seat frame is provided with a mounting tube which is mounted on a top portion of the retractable rod and rested on the stop flange of the retractable rod, so that the seat frame may be rotated on the retractable rod freely.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to
FIGS. 1 and 2
, a gardening working vehicle structure
1
in accordance with a preferred embodiment of the present invention comprises a vehicle frame
10
, two wheels
20
, and a seat frame
50
.
The vehicle frame
10
has two ends respectively provided with two opposite pivot portions
11
each formed with a pivot hole
110
. Two wheels
20
are provided, and each of the two wheels
20
is rotatably mounted between two opposite pivot portions
11
of the vehicle frame
10
, so that the vehicle frame
10
may be moved horizontally. Each of the two wheels
20
has a center provided with a shaft whose two ends are mounted in the pivot holes
110
of the pivot portions
11
of the vehicle frame
10
, so that the two wheels
20
may be rotatably mounted between the two ends of the vehicle frame
10
. The vehicle frame
10
has a top face provided with a seat tube
12
extending outward.
A quick release set
30
is mounted on a top portion of the seat tube
12
. The quick release set
30
includes a clamping tube
31
mounted on an outer periphery of the seat tube
12
, and a snapping member
32
mounted on the clamping tube
31
for clamping the clamping tube
31
on the seat tube
12
.
A retractable rod
40
is adjustably mounted on the seat tube
12
, and has a first end formed with a first insertion portion
41
inserted into the seat tube
12
of the vehicle frame
10
, and has a second end formed with a second insertion portion
42
. The retractable rod
40
is formed with an annular stop flange
43
located between the first insertion portion
41
and the second insertion portion
42
.
The seat frame
50
is mounted on the retractable rod
40
, and includes a tube body
51
that is bent into an inverted U-shaped frame. The tube body
51
of the seat frame
50
has a first section formed with a horizontal support portion
52
, and a second section formed with a vertical backrest portion
53
. A seat pad
60
is secured on the support portion
52
. A backrest pad
61
is secured on a first side of the backrest portion
53
, and a support tube
530
is secured on a second side of the backrest portion
53
of the seat frame
50
.
A base plate
520
is secured on the support portion
52
of the tube body
51
of the seat frame
50
, and is provided with a mounting tube
521
which is mounted on an outer periphery of the second insertion portion
42
of the retractable rod
40
, so that the bottom of the mounting tube
521
of the base plate
520
of the seat frame
50
is rested on the stop flange
43
of the retractable rod
40
.
A positioning pin
44
is extended through an upper portion of the second insertion portion
42
of the retractable rod
40
, and is rested on a top face of the base plate
520
of the seat frame
50
, so that the mounting tube
521
of the base plate
520
of the seat frame
50
is retained between the stop flange
43
of the retractable rod
40
and the positioning pin
44
as shown in FIG.
5
. Thus, the seat frame
50
may be rotated freely on the retractable rod
40
.
As shown in
FIG. 3
, the user may be seated on the seat pad
60
of the seat frame
50
, and may move the gardening working vehicle structure
1
freely by his feet, so that the user may be seated on the gardening working vehicle structure
1
to move to any position in the garden freely and easily, without having to stand up, thereby facilitating the user proceeding the gardening work.
As shown in
FIG. 4
, the mounting tube
521
of the base plate
520
of the seat frame
50
is rotatably mounted on the second insertion portion
42
of the retractable rod
40
, so that the seat frame
50
may be rotated on the retractable rod
40
freely. Thus, the user may turn around freely to take his tool or article, thereby greatly increasing convenience of work.
As shown in
FIG. 5
, the first insertion portion
41
of the retractable rod
40
is adjustably mounted in the seat tube
12
of the vehicle frame
10
by the quick release set
30
, so that the first insertion portion
41
of the retractable rod
40
may be moved upward and downward to adjust the height of the seat frame
50
so as to fit users of different statures, thereby enhancing the versatility of the gardening working vehicle structure
1
.
As shown in
FIG. 6
, a support rod
71
of a sunshade umbrella
70
may be inserted into the support tube
530
of the backrest portion
53
of the seat frame
50
, thereby providing a sunshade effect to the user during work.
Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
