Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a support with a locking
device, and more particularly to a support with a locking device
for a barbecue, with which it is easy to adjust the height of a
barbecue grill cover to control the temperature.
[0003] 2. Description of the Related Art
[0004] A barbecue has a gas burner, a grill and a cover. The cover
is mounted over the grill to concentrate the heat and accelerate
the cooking process.
[0005] However, the cover can only be completely opened or
completely closed. Hence, when cooking, the grill is either
completely exposed or completely covered such that it is difficult
to control the temperature.
[0006] Therefore, the invention provides a support with a locking
device for a barbecue grill cover to mitigate or obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide a
support with a locking device for a barbecue grill cover with which
is easy to adjust the height of the cover to control the
temperature.
[0008] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is a partial operational perspective view of a
support with a locking device for a barbecue grill cover in
accordance with the present invention;
[0010] FIG. 2 is a perspective view of the support with a locking
device for a barbecue grill cover in FIG. 1;
[0011] FIG. 3 is an exploded perspective view of the support with a
locking device for a barbecue grill cover in FIG. 1;
[0012] FIG. 4 is an operational side view of the support with a
locking device for a barbecue grill cover in FIG. 1; and
[0013] FIG. 5 is a partial operational side view of the support
with a locking device for a barbecue grill cover in FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] With reference to FIG. 1, a barbecue has a body (10), a gas
burner (not shown) mounted in the body (10), a grill (12) mounted
on a top of the body (10), and a cover (15) pivotally mounted on a
top end of the body (10). The grill (12) is substantially
rectangular, has four sides and a frame (11) formed around the four
sides of the grill (12). A support with a locking device (20) is
mounted on the frame (11) at a front end of the grill (12). The
grill (12) is covered with the cover (15), which can be pivoted
along a rear end of the grill (12).
[0015] With further reference to FIGS. 2-3, the locking device (20)
has an upright base plate (21), a horizontal adjusting plate (22),
a locking plate (23), and a spring (24).
[0016] The base plate (21) has a bracket (211) mounted on a lower
sidewall thereof. A channel (210) is formed between the bracket
(211) and the lower sidewall of the base plate (21). The channel
(210) faces downward and has two open ends. Multiple parallel slots
(212) are transversely defined in the base plate (212).
[0017] The adjusting plate (22) has a handle (221) mounted at a
first end thereof and an up-turned end (222) formed at a second end
thereof. A slit (220) is defined transversely in a middle portion
of the adjusting plate (22) and has a larger width than the base
plate (21). Two ears (223) are respectively formed at two opposite
sides of the adjusting plate (22) and extend upwards. Corresponding
through holes are defined in each ear (223). A pin (224) is
inserted through the through holes in the ears (223).
[0018] The locking plate (23) has a V-shaped cross section forming
two wings. A first wing has a bent locking tab (230) formed at a
free end and a second wing has a bent thumb tab (231) formed at a
free end.
[0019] In assembly, the base plate (21) is inserted into the slit
(220) of the adjusting plate (22) so that the adjusting plate (22)
can be moved longitudinally along the base plate (21). The locking
plate (23) is mounted on the adjusting plate (22) between the ears
(223). The pin (224) is inserted into the through holes of the ears
(223) over the locking plate (23) so that the locking plate (23)
can pivot about the pin (224). The spring (24) is mounted between
the adjusting plate (22) and the thumb tab (231) to bias the
locking plate (23). The locking tab (230) is inserted into and
securely connected to a slot (212).
[0020] In another embodiment, the spring (24) can be mounted
between the adjusting plate (22) and the wing of the locking plate
(23) with the locking tab (230) thereby the wing is pulled downward
by the spring.
[0021] With reference to FIGS. 1 and 4, the support with a locking
device (20) is mounted on front end of the grill (12) with the
frame (11) received in the channel (211). When the cover (15) is
open, a front end of the cover (15) can be placed on an upper
surface of the adjusting plate (22), which can be positioned at a
desired height.
[0022] With further reference to FIG. 5, when the thumb tab (231)
is pressed downward the locking tab (230) separates from the slot
(212). The adjusting plate (22) can then be moved upwards or
downwards to a desired height. Then the pressure is released from
the thumb tab (231) and the locking tab (230) is inserted into
another slot (212) by a resilient force of the spring (24). Thus,
the cover (15) can be kept open at a desired height relative to the
grill (12) easily and conveniently.
[0023] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only. Changes may be made in the details, especially
in matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
