Abstract
A switch assembly for a barbecue grill includes two pipes with a connection tube integrally connected between the two pipes. The two pipes and the connection tube are made by way of casting so as to be a one-piece member. 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.
Description
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.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is an exploded view to show a conventional switch assembly of a barbecue grill,
FIG. 2
is an exploded view to show a switch assembly of a barbecue grill of the present invention;
FIG. 3
is a plan view to show the switch assembly of the present invention, and
FIG. 4
is a perspective view of the switch assembly of a barbecue grill of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 2
to
4
, the switch assembly for a barbecue grill in accordance with the present invention comprises two pipes
21
,
22
with a connection tube
23
integrally connected between the two pipes
21
,
22
. The two pipes
21
,
22
, the connection tube
23
and an extension tube
20
extending from the connection tube
23
are made by way of casting so as to be a one-piece member. The connection tube
23
has a groove
24
defined in a top thereof and the groove
24
communicates with the two pipes
21
,
22
. A slit
26
is defined in a top edge of the top of the connection tube
23
so that a seal ring
42
is engaged with the slit
26
.
A cap
32
is connected to the top of the connection tube
23
to seal the groove
24
. Four first lugs
25
extend from two sides of the connection tube
23
and the cap
32
has four second lugs
30
and each second lug
30
having a hole
33
. The second lugs
30
are connected to the first lugs
25
by extending bolts
40
through washers
41
, the holes
33
in the second lugs
30
and threadedly engaged with the first lugs
25
.
The position relationship between the two pipes
21
,
22
and the connection tube
23
can be precisely maintained as desired because they are made infegrally by way of casting.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
Claims
- 1. A switch assembly for a barbecue grill, comprising:two pipes with a connection tube integrally connected between said two pipes, said connection tube having a groove defined in a top thereof and said groove communicating with said two pipes, a slit defined in a top edge of said top of said connection tube and a seal ring engaged with said slit, four first lugs extending from two sides of said connection tube, and a cap having four second lugs and each second lug having a hole, said second lugs connected to said first lugs by bolts extending through said holes in said second lugs and threadedly engaged with said first lugs to seal said top of said groove.
