Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an oil collection tray. The
same oil collection trays can be piled up and taken out with ease
to decrease the volume for transportation and to lower the
cost.
[0003] 2. Description of the Prior Art
[0004] FIG. 5 through FIG. 8 and FIG. 5-A are to show a
conventional oil collection tray A. As shown in FIG. 5 and FIG.
5-A, the middle section of the tray body Al of the oil collection
tray A has a datum line A0. The outer diameter of the portion above
the datum line A0 is larger than that of the portion below the
datum line A0, so that a striding face A10 is formed at the
position of the datum line A0. The portion above the striding face
A10 is called as a large tray body A101, and the portion below the
striding face A10 is called as a small tray body A102. The outer
diameter of the small tray body A102 is about equal to the inner
diameter of the large tray body A101. The oil collection tray A has
an oil nozzle A2 at one side thereof. The oil nozzle A2
communicates with the inside of the oil collection tray A.
Referring to FIG. 6 and FIG. 7, a number of the conventional oil
collection trays A are piled up, the small tray body A102 of the
upper oil collection tray A is placed into the large tray body A101
of the lower oil collection tray A. The striding face A10 of the
upper oil collection tray A is placed on top of the flange All of
the lower oil collection tray A. As shown in FIG. 8, the oil
collection trays are piled up to reduce the volume for
transportation. The conventional oil collection tray has the
problems as below.
[0005] 1. The height of the small tray body below the striding face
is less than that of the large tray body for piling the oil
collection trays. If the height of the small tray body below the
striding face is greater than that of the large tray body, the
upper tray body can't be placed into the lower tray body smoothly
because the air inside the lower tray body causes a resistance to
the upper tray body, as shown in FIG. 6. That's the reason why the
height of the small tray body is less than that of large tray body.
When piling the oil collection trays, the small tray body has less
resistance to exclude the air with ease so that the small tray body
of the upper oil collection tray can be placed into the large tray
body of the lower oil collection tray and blocked by the striding
face, as shown in FIG. 7. The number of the piled oil collection
trays is limited. This increases the volume and the cost, as shown
in FIG. 8.
[0006] 2. When piling the conventional oil collection trays, the
same oil collection trays cannot be positioned in the same
direction as shown in FIG. 7 and the piled oil collection trays may
be turned. The oil nozzles of the oil collection trays cannot be
positioned at the same perpendicular line so the oil collection
trays are untidy and disordered. The space cannot be used
effectively. Besides, the protruding oil nozzles occupy a lot of
space.
[0007] Accordingly, the inventor of the present invention has
devoted himself based on his many years of practical experiences to
solve these problems.
SUMMARY OF THE INVENTION
[0008] The primary object of the present invention is to provide an
oil collection tray. The oil collection tray comprises a flange and
a tray body which is inclined inward. The tray body has an inner
wall which is inclined inward. The tray body has a plurality of
spaced vertical recesses formed on an outer wall thereof and a
plurality of protruding ribs formed on the inner wall thereof
corresponding in position to the vertical recesses. When a number
of oil collection trays are piled up, the tray body of the upper
oil collection tray is placed into the tray body of the lower oil
collection tray. The tray body of the upper oil collection tray
extrudes the air O inside the tray body of the lower oil collection
tray. The air O is expelled from the gaps defined between the
protruding ribs of the tray body of the lower oil collection tray
and the vertical recesses of the tray body of the upper oil
collection tray until the vertical recesses of the tray body of the
upper oil collection tray mate with the protruding ribs of the tray
body of the lower oil collection tray. The flange of the upper oil
collection tray is located on top of the flange of the lower oil
collection tray. In this way, the same oil collection trays can be
piled up with ease to decrease the volume for transportation and to
lower the cost.
[0009] The outer wall of the tray body of the oil collection tray
is formed with the plurality of vertical recesses, and the inner
wall of the tray body of the oil collection tray is formed with the
plurality of protruding ribs corresponding in shape to the vertical
recesses. When the oil collection trays are piled up, the vertical
recesses of the tray body of the upper oil collection tray will
mate with the protruding ribs of the tray body of the lower oil
collection tray. The oil collection trays in the same specification
can be piled up. Through the protruding ribs of the tray body of
the lower oil collection tray to engage with the vertical recesses
of the tray body of the upper oil collection tray, the piled oil
collection trays can be positioned in the same direction. The oil
nozzles of the oil collection trays are positioned in the same
perpendicular line, so that the oil collection trays can be piled
orderly and stored easily to decrease the storage space.
[0010] The vertical recesses of the tray body of the oil collection
tray extend to the bottom of the oil collection tray to form
L-shaped recesses. When the tray body of the upper oil collection
tray is placed into the tray body of the lower oil collection tray,
the air O will be expelled from the L-shaped recesses to expel the
air smoothly.
[0011] The vertical recesses of the tray body of the oil collection
tray have a tapered shape and the protruding ribs also have a
tapered shape corresponding in shape to the vertical recesses, so
that the tapered protruding ribs of the tray body of the lower oil
collection tray can mate with the tapered vertical recesses of the
tray body of the upper oil collection tray with ease to provide an
alignment effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Embodiments of the present invention will now be described,
by way of example only, with reference to the accompanying
drawings.
[0023] As shown in FIG. 1 to FIG. 4 and FIG. 1-A, an oil collection
tray 1 of the present invention comprises a flange 11 and a tray
body 12 which is inclined inward. The tray body 12 has an inner
wall which is inclined inward. The tray body 12 has a plurality of
spaced vertical recesses 121 formed on an outer wall thereof and a
plurality of protruding ribs 122 formed on the inner wall thereof
corresponding in position to the vertical recesses 121. As shown in
FIG. 2 and FIG. 3, when a number of oil collection trays 1 are
piled up, the tray body 12 of the upper oil collection tray 1 is
placed into the tray body 12 of the lower oil collection tray 1.
The tray body 12 of the upper oil collection tray 1 extrudes the
air O inside the tray body 12 of the lower oil collection tray 1.
The air O is expelled from the gaps defined between the protruding
ribs 122 of the tray body 12 of the lower oil collection tray 1 and
the vertical recesses 121 of the tray body 12 of the upper oil
collection tray 1 until the vertical recesses 121 of the tray body
12 of the upper oil collection tray 1 mate with the protruding ribs
122 of the tray body 12 of the lower oil collection tray 1. The
flange 11 of the upper oil collection tray 1 is located on top of
the flange 11 of the lower oil collection tray 1. In this way, the
same oil collection trays 1 can be piled up with ease to decrease
the volume for transportation and to lower the cost, as shown in
FIG. 4.
[0024] As shown in FIG. 3 and FIG. 4, the outer wall of the tray
body 12 of the oil collection tray 1 is formed with the plurality
of vertical recesses 121, and the inner wall of the tray body 12 of
the oil collection tray 1 is formed with the plurality of
protruding ribs 122 corresponding in shape to the vertical recesses
121. When the oil collection trays 1 are piled up, the vertical
recesses 121 of the tray body 12 of the upper oil collection tray 1
will mate with the protruding ribs 122 of the tray body 12 of the
lower oil collection tray 1. The oil collection trays 1 in the same
specification can be piled as desired, as shown in FIG. 3 and FIG.
4. Through the protruding ribs 122 of the tray body 12 of the lower
oil collection tray 1 to engage with the vertical recesses 121 of
the tray body 12 of the upper oil collection tray 1, the piled oil
collection trays 1 can be positioned in the same direction. The oil
nozzles 13 of the oil collection trays 1 are positioned in the same
perpendicular line X, as shown in FIG. 3 and FIG. 4, so that the
oil collection trays 3 can be piled orderly and stored easily to
decrease the storage space.
[0025] As shown in FIG. 3, the vertical recesses 121 of the tray
body 12 of the oil collection tray 1 extend to the bottom of the
oil collection tray 1 to form L-shaped recesses 1211. When the tray
body 12 of the upper oil collection tray 1 is placed into the tray
body 12 of the lower oil collection tray 1, the air O will be
expelled from the L-shaped recesses 121 to expel the air
smoothly.
[0026] Referring to FIG. 1 to FIG. 4, the vertical recesses 121 of
the tray body 12 of the oil collection tray 1 have a tapered shape
and the protruding ribs 122 also have a tapered shape corresponding
in shape to the vertical recesses 121, so that the tapered
protruding ribs 122 of the tray body 12 of the lower oil collection
tray 1 can mate with the tapered vertical recesses 121 of the tray
body 12 of the upper oil collection tray 1 with ease to provide an
alignment effect.
[0027] FIG. 4 and FIG. 8 show a comparison between the oil
collection tray 1 of the present invention (as shown in FIG. 1) and
the conventional oil collection tray A (as shown in FIG. 5). As
shown in FIG. 4, the number of the piled oil collection trays 1 of
the present invention is three and the height is H1. As shown in
FIG. 8, the number of the conventional oil collection trays A is
two and the height is H2. The height H1 is about equal to the
height H2. Thus, at the same height, the number of the oil
collection trays 1 of the present invention is greater than the
number of conventional oil collection trays A. In other words, at
the same number, the height of the oil collection trays 1 of the
present invention is less than the height of conventional oil
collection trays A. The oil collection trays of present invention
can be piled up with ease to decrease the volume for transportation
and to lower the cost
[0028] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
