ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a handle of a rotisserie, more particularly one that can be easily removed from, and connected to, a rotary element of the rotisserie.
2. Brief Description of the Prior Art
Referring to
FIG. 5
, a conventional barbecue oven has a support frame
10
, a platform
11
disposed on top of the support frame
10
, and a rotisserie positioned on the platform
11
. The platform
11
includes a left smooth area
12
for the users to process and cut foods thereon, a middle roasting area
13
for roasting foods with, and a right cooking area
14
next to the roasting area
13
for heating foods with. The rotisserie consists of a frame
15
securely disposed next to a rear edge of the roasting area
13
, a rotary support
16
, and a handle
18
; the rotary support
16
has forks
17
at two ends thereof for fixing foods to be roasted to the support
16
; the frame
15
is formed with two opposing gaps
151
; two ends of the rotary support
16
can be passed into the gaps
151
so that the rotary support
16
can be turned on the frame
15
. The handle
18
is detachably joined to a right tail end of the rotary support
16
for operating the support
16
with.
The handle
18
is removed from the support
16
so that it will not become an obstacle when the users are cooking foods on the cooking area
14
.
Referring to
FIG. 6
, the handle
18
has a metallic tube
181
fitted therein, which is formed with screw threads on an inner side, while the tail end of the support
16
is formed with screw threads
161
on an outer side; thus, the handle
18
can be joined to the support
16
by means of screwing the metallic tube
181
around the threaded tail end of the support
16
, and can be removed from the support
16
when it is turned relative to the support
16
in the loosening direction.
However, the above rotisserie is found to have disadvantages as followings:
1. The users have to turn the rotary support frequently on the course of using the barbecue oven therefore they have to make the handle connected to, and then separate from, the rotary support
16
frequently. Consequently, the installation and removal of the handle
18
causes the user relatively much labor and time because the user have to hold the rotary support
16
, and the handle
18
with her left and right hands respectively while she is screwing the handle
18
off the support
16
.
2. The user might get burned when she is trying to make the rotary support
16
stay still to screw the handle
18
off the support
16
because she has to hold the rotary support with one hand, and because the rotary support is very hot on the course of roasting meat with the rotisserie.
SUMMARY OF THE INVENTION
It is a main object of the present invention to provide a handle to a rotisserie, which can be easily removed from, and connected to, a rotary support of the rotisserie.
The rotary support has an annular trench at a tail end while the handle has a middle hole at a first section, and several through holes extending from the outer side to communicate with the middle hole. Beads are each movably fitted in one of the through holes of the handle, and a spring-biased tube is passed around the handle so as to force the beads to project into the middle hole with an inner side of a first section of the tube. The tube has an annular slope on an inner side of an end portion, which is next to the first section thereof. The rotary support is closely inserted into the middle hole with the beads engaging the annular trench to prevent the handle from separating from the rotary support. When the tube is slid so that the annular slope thereof faces the beads, the beads are allowed to move out of the annular trench, and in turns, the handle can be separated from the support.
