Description
FIELD OF THE INVENTION
[0001] The present invention relates to a positioning device used
on a rack, and more particularly, to a positioning device for more
securely position equipment unit on the rack.
BACKGROUND OF THE INVENTION
[0002] Generally, there are multiple equipment units such as
servos, cased computers and electronic appliances connected to a
rack so as to save space. In order to allow each of the equipment
units to be pulled from the rack for convenience of maintenance,
each equipment unit is cooperated with two slide assemblies or
support frames on two sides thereof so that the equipment units can
be retracted in the rack and positioned by the slide assemblies or
support frames.
[0003] The conventional way for positioning the equipment units is
to use lugs on the front board and the lugs have holes or bolts to
connect the rack to prevent the equipment units from dropping out
from the rack.
[0004] However, some of the equipment units are heavy so that when
they are transported, the lugs on the front board connected between
the rack and the front end of the servo is not strong and secure.
Similarly, the racks cannot bear vibration when in use.
SUMMARY OF THE INVENTION
[0005] The present invention intends to provide a positioning
device used on a rack which securely connects the equipment unit to
the rack in a frequent vibration environment.
[0006] The present invention relates to a positioning device which
comprises a first board having a first positioning portion
extending therefrom and a first hole is defined through the first
positioning portion. A second board is located corresponding to the
first board and has a second positioning portion which is located
corresponding to the first positioning portion. The second
positioning portion is bent from the second board and has a second
hole. A connection portion is connected to the first and second
boards. A hook extends from one of the first board, the second
board and the connection portion.
[0007] Preferably, the first positioning portion is substantially
perpendicular to the first board and the second positioning portion
is substantially perpendicular to the second board.
[0008] Preferably, the first board has an extension portion
extending from a top thereof.
[0009] Preferably, the extension portion is substantially
perpendicular to the first board.
[0010] Preferably, the hook is a U-shaped hook.
[0011] Preferably, the hook extends from a conjunction of the first
board, the second board and the connection portion.
[0012] 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, a preferred embodiment in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] Referring to FIGS. 1 and 2, the positioning device 10 of the
present invention comprises a first board 12, a second board 14
located corresponding to the first board 12, a connection portion
16 connected to the first and second boards 14, 16, and a hook 18
extending from one of the first board 12, the second board 14 and
the connection portion 16. Preferably, the hook 18 extends from a
conjunction of the first board 12, the second board 14 and the
connection portion 16, and the hook 18 is a U-shaped hook. The
first board 12 has a first positioning portion 20 extending
therefrom and a first hole 22 is defined through the first
positioning portion 20. The second board 14 has a second
positioning portion 24 which is located corresponding to the first
positioning portion 20. The second positioning portion 24 is bent
from the second board 14 and has a second hole 26. The first
positioning portion 20 is substantially perpendicular to the first
board 12 and the second positioning portion 24 is substantially
perpendicular to the second board 14.
[0023] FIGS. 3 and 4 show an equipment unit 28, two vertical
support columns 30 on the rear side of a rack, and two support
frames 32 connected between the equipment unit 28 and the two
vertical support columns 30. The support frames 32 have two
connection boards 34 which face to each other and support the
bottom of the equipment unit 28. Each of the vertical support
columns 30 has multiple installation holes 36 and each support
frame 32 has at least two pins 38 and a stop member 40. The pins 38
are inserted through the installation holes 36 of the vertical
support columns 30 so as to hang the support frames 32. The stop
members 40 contact the vertical support columns 30 so that the pins
38 are not separated from the installation holes 36. There are
threaded holes 42 defined in the support frames 32 and located at
the alignment lines to the pins 38. Referring to FIG. 5, the
equipment unit 28 has a side wall 44 which protrudes from the rear
side of the equipment unit 28 and is located adjacent to the
vertical support column 30.
[0024] FIGS. 6 and 7 show that the positioning device 10 is
connected between the equipment unit 28 and the vertical support
column 30, wherein the hook 18 of the positioning device 10 hooks
the side wall 44 of the equipment device 28. The first board 12,
the second board 14 and the connection portion 16 substantially
contact the side of the equipment unit 28. The first and second
positioning portions 20, 24 are located corresponding to two of the
installation holes 36 of the vertical support column 30. The first
positioning portion 20 is connected to one of the installation
holes 36 by a locking unit, and the locking unit includes a first
bolt 46 and a threaded part 48. The first bolt 46 extends through
the first hole 22 of the first positioning portion 20 and is
connected to the threaded part 48.
[0025] The second positioning portion 24 is connected to the
threaded hole 42 of the support frame 32 by a second bolt 50
inserting through the second hole 26 of the second positioning
portion 24. By the engagement of the hook 18 of the positioning
device 10 and the side wall 44 of the equipment unit 28, the
equipment unit 28 is prevented from shaking.
[0026] FIGS. 8 and 9 show that the first board 12 has an extension
portion 52 extending from a top thereof and the extension portion
52 contacts the top of the equipment unit 28 so that the equipment
unit 28 is securely clamped between the extension portion 52 of the
positioning device 10 and the connection board 34 of the support
frame 32 as shown in FIG. 3. The equipment unit 28 is securely
connected relative to the vertical support column 30. In a
preferable embodiment, the extension portion 52 is substantially
perpendicular to the first board 12 of the positioning device
10.
[0027] The equipment unit 28 is securely connected to the rack by
the positioning device 10 and ensured to be firmly secured in the
rack during a frequent vibration environment.
[0028] While we have shown and described the embodiment 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 of the present invention.
