A portable gas burner in which the base is comprised of a hollow disk-like shell and a plurality of sector plates detachably fastened to one another and to the periphery of the disk-like shell by screws; the reflector is comprised of a reflector disk and a plurality of sector plates detachably fastened to one another and to the periphery of the reflector disk by screw rods and wing nuts, which screw rods being respectively formed integral with the sector plates of the reflector.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a portable gas burner and, more specifically, to such a portable gas burner, which has a detachable reflector and a detachable base.





FIG. 9

shows a portable gas burner according to the prior art. This structure of gas burner


3


comprises a base


33


, a burner body


31


supported on the base


33


, and a reflector


32


suspended above the burner body


31


. This structure of portable gas burner is functional, however it still has drawbacks. In order to effectively reflect the light and heat downwards from the burner body


31


and to support the portable gas burner stably on a flat surface, the reflector


32


and the base


33


must have a broad area (diameter). However, because the base


33


and the reflector


32


are not detachable, the portable gas burner occupies much storage space when not in use or during its delivery.




SUMMARY OF THE INVENTION




The present invention has been accomplished to provide a portable gas burner, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide a portable gas burner, which has a detachable reflector and a detachable base. It is another object of the present invention to provide a detachable base and a detachable reflector for a portable gas burner that are inexpensive to manufacture. It is still another object of the present invention to provide a detachable reflector and a detachable base for a portable gas burner that have a strong structural strength. According to one aspect of the present invention, the base for the portable gas burner is comprised of a hollow disk-like shell and a plurality of sector plates detachably fastened to one another and to the periphery of the disk-like shell by screws. According to another aspect of the present invention, the reflector for the portable gas burner is comprised of a reflector disk and a plurality of sector plates detachably fastened to one another and to the periphery of the reflector disk by screw rods and wing nuts, which screw rods being respectively formed integral with the sector plates of the reflector. According to still another aspect of the present invention, the sector plates of the reflector each have a scrolled outer end portion and reinforcing ribs to reinforce the structural strength.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1 and 2

, a portable gas burner is shown having a base


2


, which supports the portable gas burner stably on a flat surface, and a reflector


1


, which reflects light and light from the burner unit of the portable gas burner downwards. The reflector


1


and the base


2


are detachable.




Referring to FIGS. from


3


through


5


and

FIGS. 1 and 2

again, the reflector


1


comprises a reflector disk


11


, and a reflector rim R


1


mounted around the reflector disk


11


. The reflector disk


11


has a plurality of mounting holes


111


equiangularly spaced around the border thereof. The reflector rim R


1


is comprised of a plurality of sector plates


12


, each sector plate


12


having a plurality of upright mounting screws


121


and mounting holes


122


. By means of inserting the respective upright mounting screws


121


into the respective mounting holes


111


and


122


and then threading respective wing nuts


123


onto the upright mounting screws


121


, the sector plates


12


and the reflector disk


11


are fixedly fastened together.




Referring to

FIGS. 6 and 7

, the base


2


is comprised of a hollow, disk-like shell


21


, and a rim R


2


mounted around the disk-like shell


21


. The disk-like shell


21


has a plurality of screw holes


211


equiangularly spaced around the periphery. The rim R


2


is comprised of a plurality of sector plates


22


, each sector plate


22


having an upward mounting flange


221


and a plurality of screw holes


222


. Screws


223


are respectively fastened to the screw holes


222


and


211


to fixedly secure the sector plates


22


to one another and to the disk-like shell


21


, keeping the sector plates


22


partially overlapped on one another and the upward mounting flange


221


connected to the periphery of the disk-like shell


21


.




Referring to

FIGS. 3 and 5

again, the sector plates


12


of the reflector


1


each have a scrolled outer end portion


124


and reinforcing ribs


125


that reinforce the structural strength of the respective sector plate


12


.




Referring to

FIG. 7

, the disk-like shell


21


of the base


2


has a scrolled outer end portion


212


.




Referring to

FIG. 8

, the diameter of the base


2


is increased from D


1


(the diameter of the disk-like shell


21


) to D


2


when the sector plates


22


installed.




As indicated above, the reflector


1


and the base


2


are detachable. The parts of the reflector


1


and the base


2


are detached from one another and packed in a box to minimize space occupation during the delivery from the factory to the distributor. Because the reflector


1


and the base


2


are respectively formed of a number of parts, the small parts of the reflector


1


and the base


2


are easy to manufacture. When assembled, the broad supporting area of the base


2


supports the portable gas burner stably on a flat surface, and the reflector


1


provides a broad reflecting surface to reflect light and heat from the burner unit of the portable gas burner to a broad area.




A prototype of portable gas burner with detachable reflector and base has been constructed with the features of the annexed drawings of FIGS.


1


˜


8


. The portable gas burner with detachable reflector and base functions smoothly to provide all of the features discussed earlier.




Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
