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.
