Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a point-of-sale (POS)
system and, more particularly, to a POS system with a display
viewing angle adjustment device capable of adjusting a viewing
angle of a display of the POS system with a more flexible
range.
2. Description of the Related Art
[0002] To keep abreast with technological progress, cash registers
back in early days with tiny display and primitive sale amount
counting and receipt printing functions have been advanced to
latest POS systems integrating touch screen, printer and a
multitude of functions in handling transactions and inventory of
merchandise as a whole, thereby boosting convenience of retail
vendors or store clerks in keeping track of inventory and
transactions of merchandise at all times.
[0003] With reference to FIG. 6, a conventional POS system includes
a base 90, a support arm 91 and a touch screen 92 pivotally mounted
on the support arm 91. Because there is no enough space between the
touch screen 92 and the base 90 for freely tilting the touch screen
92, the touch screen tends to hit the base 90, especially upon
downward tilt of the touch screen, and is allowed for limited
tilting angle adjustment. However, due to the differences in
operator's height and/or operation environment, when a store clerk
or a retail vendor is accessing customer pickup information or
merchandise information and is also squatting to vendor to view the
information on the display of the POS system while remaining in a
squatting position because of the limited tilting range of the
touch screen 92.
SUMMARY OF THE INVENTION
[0004] An objective of the present invention is to provide a
point-of-sale (POS) system with a display viewing angle adjustment
device allowing to conveniently adjust the display viewing angle of
a display of the POS system.
[0005] To achieve the foregoing objective, the POS system with a
display viewing angle adjustment device includes a screen, a fixing
plate, a support plate and a base.
[0006] The screen has a rear cover.
[0007] The fixing plate is securely mounted on the rear cover of
the screen and has two slide slots formed through the fixing
plate.
[0008] The support plate is mounted between the rear cover of the
screen and the fixing plate and has two side legs respectively
formed on and protruding rearwards from a left edge and a right
edge of the support plate and slidably mounted through the
respective slide slots of the fixing plate to be movable within the
respective slide slots in a downward or upward direction.
[0009] The base has a support arm pivotally connected with the side
legs of the support plate.
[0010] According to the foregoing structure, when users intend to
increase an adjustment range of display viewing angle of the
screen, a measure using the support plate and the support arm to
support the screen allows the screen to be further moved up through
the slid slots. Such measure can increase movement space between
the screen and the base and the adjustment range of display viewing
angle as well. The combination of the fixing plate and the support
plate increases the range of display viewing angle and therefore
renders operational convenience to users in operation of the POS
system.
[0011] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0018] With reference to FIGS. 1 and 2, a point-of-sale (POS)
system with a display viewing angle adjustment device in accordance
with the present invention includes a screen 10, a fixing plate 20,
a support plate 30 and a base 40. The fixing plate 20 is securely
mounted on a rear cover 11 of the screen 10. The support plate 30
is mounted between the rear cover 11 of the screen 10 and the
fixing plate 20. The base 40 has a support arm 41 pivotally
connected with the support plate 30.The screen 10 may be a touch
screen.
[0019] With reference to FIGS. 2 and 3, the fixing plate 20 has two
slide slots 21, a pivot seat 22, a recess 23, resilient element 24,
a first positioning hole 25, and an adjustment switch 26. The two
slide slots 21 are parallelly and vertically formed through the
fixing plate 20. The pivot seat 22 is mounted on a rear surface of
the fixing plate 20 and is located between the two slide slots 21.
The recess 23 is formed in the rear surface of the fixing plate 20
and is located above the recess 23 and between the two slide slots
21. The resilient element 24 is inserted into the recess 23. The
first positioning hole 25 is formed through the fixing plate 20 and
is located below the pivot seat 22 and between the two slide slots
21. The adjustment switch 26 is elongated in a vertical direction,
is pivotally mounted on the pivot seat 22, and has a pivoting
portion 261, a pressing portion 262 and a positioning protrusion
263. The pivoting portion 261 is formed on a rear surface of the
adjustment switch 26 and is located between a top end and a bottom
end of the adjustment switch 26. A pin 50 is mounted through the
pivoting portion 261 and the pivot seat 22 of the fixing plate 20
for the adjustment switch 26 to be pivotable with respect to the
pivot seat 22. The pressing portion 262 is formed on the top end of
the adjustment switch 26, and corresponds to the recess 23 of the
fixing plate 20. The positioning protrusion 263 is formed on a
front surface of the adjustment switch 26, is located at the bottom
end of the adjustment switch 26, and corresponds to the first
positioning hole 25 of the fixing plate 20. Before the pressing
portion 262 is pressed, the positioning protrusion 263 is kept in
the first positioning hole 25. When the pressing portion 262 is
pressed, the pressing portion 262 is inserted into the recess 23
and compresses the resilient element 24 while the positioning
protrusion 263 escapes from the first positioning hole 25. After
the pressing portion 262 is released, the elastic restoring force
of the resilient element 24 ejects the pressing portion 262 and the
positioning protrusion 263 returns to the first positioning hole
25. In the present embodiment, the resilient element 24 is a
spring.
[0020] The fixing plate 20 has four corners with one through hole
formed through each corner. The rear cover 11 of the screen 10 has
four threaded holes formed in the rear cover 11 and corresponding
to the four respective through holes of the fixing plate 20. Four
bolts are respectively mounted through the fixing plate 20 and
mounted in the rear cover 11 of the screen 10 to fasten the fixing
plate 20 on the rear cover 11 of the screen 10.
[0021] The support plate 30 has two side legs 31 and a second
positioning hole 32. The two side legs 31 are respectively formed
on and protrude rearwards from a left bottom edge and a right
bottom edge of the support plate 30, are respectively and slidably
mounted through the slide slots 21 of the fixing plate 20 to be
movable within the respective slide slots 21 in a downward or
upward direction, and are pivotally connected with two opposite
portions of a top end of the support arm 41 of the base 40, such
that the screen 10 is supported by the support plate 30 and the
support arm 41 and can be moved up and down along the two slide
slots 21. The second positioning hole 32 is formed through the
support plate 30 and corresponds to the first positioning hole 25
of the fixing plate 20.
[0022] The fixing plate 20 further has multiple slotted holes
vertically formed through the fixing plate 20. The support plate 30
also has multiple threaded holes corresponding to the respective
slotted holes of the fixing plate 20, such that multiple bolts can
be sequentially mounted through the respective slotted holes of the
fixing plate 20 and mounted in the respective threaded holes of the
support plate 30 for the support plate 30 to be held between the
screen 10 and the fixing plate 20 and to be movable in downward and
upward direction with respect to the fixing plate 20.
[0023] With reference to FIG. 3, the support arm 41 further has a
pivoting member 42 mounted inside the top end of the support arm
41. The pivoting member 42 is cylindrical and has two leg rests 421
respectively formed on and protruding outwards from a left end face
and a right end face of the pivoting member 42. In the present
embodiment, each side leg 31 has a guide slot 33 formed in a free
end of the side leg 31, corresponding to one of the leg rests 421,
and pivotally connected to the leg rest 421. The pivoting member 42
further has multiple threaded holes formed in the left end face and
the right end face of the pivoting member 42. Each side leg 31 also
has multiple threaded holes formed through the side leg 31 and
corresponding to the multiple threaded holes on one of the left end
face and the right end face of the pivoting member 42. Multiple
bolts can be sequentially mounted through the respective threaded
holes on the side legs 31 of the support plate 30 and the
respective threaded holes on the left end face and the right end
face of the pivoting member 42 to respectively fasten the side legs
31 on the left end face and the right end face of the pivoting
member 42, such that the screen 10 can be securely connected with
the pivoting member 42 upon being tilted.
[0024] With reference to FIGS. 4 and 5, operation of the POS system
is described as follows. When the screen 10 is adjusted and lifted
up to an upper limit point along a vertical direction, the
positioning protrusion 263 of the adjustment switch 26 engages the
first positioning hole 25 of the fixing plate 20 and the second
positioning hole 32 of the support plate 30. When the screen 10 is
adjusted and lowered to a lower limit point along the vertical
direction, the positioning protrusion 263 of the adjustment switch
26 of the adjustment switch 26 engages the first positioning hole
25 of the fixing plate 20 and abuts against a lower edge of the
support plate 30. Therefore, when moved up or down to the upper
limit point or the lower limit point, the screen 10 can be fixed at
the position.
[0025] When users intend to adjust viewing angle of the screen 10,
supposing that the screen 10 is intended to tilt in a downward
direction, the screen 10 needs to be lifted up in the vertical
direction first. First of all, the pressing portion 262 of the
adjustment switch 26 is pressed to compress the resilient element
24. The positioning protrusion 263 of the adjustment switch 26
disengages from the first positioning hole 25 of the fixing plate
20 and the lower edge of the support plate 30 and the screen 10 can
be lifted up until the screen 10 reaches the upper limit point.
Meanwhile, the second positioning hole 32 of the support plate 30
is aligned with the first positioning hole 25 of the fixing plate
20. After the pressing portion 262 of the adjustment switch 26 is
released, the elastic restoring force of the resilient element 24
brings the positioning protrusion 263 back to the first positioning
hole 25 of the fixing plate 20 and the second positioning hole 32
of the support plate 30, thereby securing the screen 10 fixed at
the adjusted viewing angle and ruling out the chance of sliding
movement.
[0026] Because a movement space between the screen 10 and the base
40 is available after users lift up the screen vertically, the
movement space allows the screen 10 to tilt down. Given the
foregoing structure and operation, tilting angle of the screen
becomes more flexible and the range of viewing angle of the screen
can be further increased.
[0027] 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 detail, 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.
