ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a switch assembly for a barbecue grill and the switch assembly includes two pipes with a connection tube connected therebetween. The switch assembly is made as a one-piece member.
BACKGROUND OF THE INVENTION
A conventional switch assembly is shown in FIG.
1
and generally includes two pipes
11
,
12
with a connection tube
10
connected between the two pipes
11
,
12
. Each pipe
11
/
12
has a threaded fitting
111
extending therefrom and the connection tube
10
has two threaded holes in two ends thereof so that the two pipes
11
,
12
are respectively connected to the connection tube
10
by threading the two threaded fittings
111
with the two threaded holes. When connecting the pipes
11
,
12
to the connection tube
10
, the pipes
11
,
12
are rotated to fasten the engagement of the threaded fittings
111
with the threaded holes. It is to be noted that each of the two pipes
11
,
12
has an inclined section
110
/
120
for being connected to other parts. Nevertheless, because the two pipes
11
,
12
have to be rotated to be connected to the connection tube
10
so that a distance “D” between the two inclined sections
110
,
120
could not be maintained. Furthermore, a pre-determined angle “A” that each pipe
11
/
12
is supposed to be could not maintained because of the threading engagement. It takes a lot of time to respectively connect the pipes
11
,
12
to the connection tube
10
for assemblers.
The present invention intends to provide a switch assembly for a barbecue grill wherein the pipes and the connection tube are made to be a one-piece member so that the distance “D” and the angle “A” can be precisely maintained.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a switch assembly for a barbecue grill and comprising two pipes with a connection tube integrally connected between the two pipes. The connection tube has a groove defined in a top thereof and the groove communicates with the two pipes. A cap is connected to the top of the connection tube to seal the groove.
The object of the present invention is to provide an integrally made switch assembly for a barbecue grill so that the position relationship between the pipes and the connection tube can be precisely maintained.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
