The heater has a base seat mounted with an isolation plate, a pair of semi-stacking male tubes with multiple corners and a screw nut with a circular press plate at the top end thereof, and the two ends of the isolation plate are connected to the bottom inner edge of the base seat for securing and the center of the isolation plate is provided with a recessed sunken seat which is engageable with the multiple corners of the male tubes, and the center of the sunken seat is provided with through hole for mounting with a pair of the semi-stacking male tubes and the external diameter of the male tubes is smaller than an umbrella hole on the table surface, and is engageable with a screw nut, thereby when the base seat is placed on the table, the male tube is inserted into the umbrella hole and the screw nut is mounted to the male tube from the bottom of the table and the bottom edge of the base seat and the circular press plate clip the edged wall of the umbrella hole so that the heater is secured to the table.

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention relates to a heater, and in particular, a heater for outdoor use which can be placed on an outdoor table or the like.

(b) Description of the Prior Art

An outdoor table10with a collapsible umbrella30, as shown inFIG. 1, is commonly found in garden or at picnic area. The table surface11has an umbrella30mounted into an umbrella hole20on the table surface11. In winter or on a cold weather, the umbrella30is replaced with a heater40, as shown inFIG. 2, which provides heat and illumination. The heater40is an upright structure with a lamp hood41at the top of the heater40. The bottom of the heater40is a base seat42connected to a tube51connected to a tank50containing LPG through the umbrella hole20. By triggering the ignition button43of the heater40, a flame is obtained at the mouth44of the heater40to provide warmth and illumination. Conventional heater40only has the base seat42to sit on the table surface and there is no other element to prevent the heater40from toppling. Accordingly, it is an object of the present invention to provide a heater for outdoors which can mitigate the above drawback.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention is to provide an improved structure of a heater for outdoor table having a base seat mounted with an isolation plate, a pair of semi-stacking male tubes with multiple corners and a screw nut with a circular press plate at the top end thereof, and the two ends of the isolation plate are connected to the bottom inner edge of the base seat for securing and the center of the isolation plate is provided with a recessed sunken seat which is engageable with the multiple corners of the male tubes, and the center of the sunken seat is provided with through hole for mounting with a pair of the semi-stacking male tubes and the external diameter of the male tubes is smaller than an umbrella hole on the table surface, and is engageable with a screw nut, thereby when the base seat is placed on the table, the male tube is inserted into the umbrella hole and the screw nut is mounted to the male tube from the bottom of the table and the bottom edge of the base seat and the circular press plate clip the edged wall of the umbrella hole so that the heater is secured to the table.

Yet another object of the present invention is to provide a heater for outdoor, wherein the surrounding of the screw nut is radially mounted with a plurality of rotating plates.

Still another object of the present invention is to provide a heater for outdoor, wherein a through hole is provided to the surrounding of the screw nut at appropriate position thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1is a perspective view of a table inserted with a collapsible umbrella.FIG. 2shows the heater to be mounted onto a table top. Referring toFIGS. 3 and 4, the heater has a base seat100having a bottom mounted with an isolation plate200, a pair of semi-stacking male tubes300,310with multiple corners301,311, and a screw nut400with a circular press plate401. The two ends of the isolation plate200are connected to the bottom inner edge of the base seat100for securing and the center of the isolation plate200is provided with a recessed sunken seat201. The sunken seat201is engageable with the corners301,311of the male tubes300,310. The center of the sunken seat201is provided with through hole202for mounting with a pair of the semi-stacking male tubes300,310. The external diameter of the male tubes300,310is smaller than the umbrella hole (not shown) on the table surface, and is engageable with the screw nut400. The external diameter of the circular press plate401of the screw nut400is larger than the umbrella hole and the surrounding of the screw nut400is mounted radially with a plurality of rotating plates402,403,404,405facilitating rotating with hands. Through holes406,407are provided to the rotating plates402,403,404,405. In addition, the surrounding of the base seat100is provided with a hole101covered with a fastening cap102to facilitate a hand to be inserted thereto to connect to a gas outlet tube51, or to place a male tubes300,310so that the corners301,311are placed to the sunken seat201.

As shown inFIG. 5, there is shown the structure of the semi-stacking male tubes300,310. The external diameter of the connector52of the gas outlet tube is larger than the tube hole of tubes300,310. The tubes300,310can be triggered halfway which can clip the gas outlet tube51into the hole of the tubes300,310. As shown inFIG. 6, the tubes300,310are stacked so that it can be slidably moved the gas outlet tube. As shown inFIG. 7, the base seat100is placed onto the table surface11of the table10and the male tubes300,310of the tube51is inserted into the umbrella hole20. The screw nut400is pressed against the male tubes300,310such that the bottom edge of the base seat and the circular press plate401clip to the edged wall of the umbrella hole. Thus, the heater of the present invention is secured to the table10. The lower holes406,407allow the tank containing LPG to be chained to the bottom of the table and the tank will not be toppled.
