DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
FIG. 1 is a perspective view illustrating the front surface of a terminal in accordance with one exemplary embodiment, and FIG. 2 is a perspective view illustrating the rear surface of the terminal in accordance with an exemplary embodiment.
As shown in FIGS. 1 and 2, a terminal 1 in accordance with this exemplary embodiment includes a display main body 10 displaying an image, a support 20 supporting the display main body 10, and a base 30 combined with the lower portion of the support 20. A controller, such as a circuit board, may be located in the base 30. In response to a device including a controller, the device is defined as a terminal, and in response to a device not including a controller, the device is defined as a display device.
The terminal 1 may be used as a cloud computing terminal which is connected to a server (not shown), may perform various tasks, and may store the performed tasks in the server (not shown). In this case, pieces of information physically located at different positions of respective terminals may be stored in the server (not shown), and thus these pieces of information may be integrated and managed.
The display main body 10 is combined with one side of the support 20, and the other side of the support 20 is combined with the base 30. The support 20 may include a head part 21 combined with the display main body 10.
The support 20 may include a height adjustment so as to adjust the height of the support 20. The height adjustment may be in a first state, i.e., a combined state in which the height of the support 20 is fixed, and in a second state, i.e., a released state in which the height of the support 20 is adjustable. A locking mechanism 40 configured to fix the height of the support 20 may be combined with one side of the support 20. This will be described later.
Further, a safety pin 50 may be combined with one side of the support 20. The safety pin 50 prevents sudden adjustment of the height of the terminal 1 when a user adjusts the height of the terminal 1. Since the safety pin 50, in addition to the locking mechanism 40, fixes the height of the support 20, the height of the support 20 may be adjusted by releasing the locking 40 after the locking 40 is combined with the support 20 and removing the safety pin 50. The safety pin 50 may prevent a safety accident which may be generated in an initial stage.
The base 30 may include an upper housing 31 and a lower housing 32. Port holes 33 with which plural ports (not shown) for operation of the controller within the base 30 and the display main body 10 are combined, may be located at one side of the base 30. A power cord combining hole, a local area network (LAN) cable combining hole, an USB combining hole, etc. may be provided as port holes 33. Although FIGS. 1 and 2 illustrate the port holes 33 as being provided on the rear surface of the lower housing 32, the position of the port holes 33 is not limited thereto.
FIG. 3 is an exploded perspective view of the base of the terminal in accordance with an exemplary embodiment.
The terminal 1, including the controller may include a circuit board 34 within the base 30. The circuit board 34 may be located between the upper housing 31 and the lower housing 32. A first hole 31a configured for combination with the support 20 is provided on the upper housing 31. A second hole 34a for combination with the support 20 is provided on the circuit board 34. The first hole 31a and the second hole 34a may be provided at corresponding positions. A combining part 32a with which the support 20 is combined may be provided on the lower housing 32. Thereby, the support 20 is combined with the combining part 32a via the first hole 31a and the second hole 34a. 
The combining part 32a may protrude in the inward direction of the base 30, in order to increase the rigidity of base 30 due to combination of the support 20 with the base 30. The support 20 may be combined with the lower housing 32 using combining members (not shown), such as screws, from a region under the lower housing 32.
The circuit board 34 serves as the controller. A device preventing the circuit board 34 from overheating may be provided on the circuit board 34. For example, a heat sink 35 preventing raising of the temperature of the circuit board 34 may be provided on the circuit board 34. Further, an air blower fan (not shown) configured to absorb heat from the circuit board 34 and then discharging the heat may be located on the lower housing 32. In order to allow the air blower fan (not shown) to absorb heat from the circuit board 34, a third hole 34b may be provided on the circuit board 34. Further, in order to allow the air blower fan (not shown) to discharge the absorbed heat, an air blowing hole 32b may be provided on the lower housing 32.
FIG. 4 is an exploded perspective view of the support in accordance with the embodiment of an exemplary present invention.
As shown in FIG. 4, the support 20 includes an outer tub 23, 24 and an inner tub 25. The outer tub 23, 24 includes a front outer tub part 24 serving as the front surface of the support 20, and a rear outer tub part 23 serving as the rear surface of the support 20. The outer tub 23 and 24 may surround at least a portion of the inner tub 25. That is, when the support 20 moves in the downward direction, and thus the length of the support unit 20 decreases, the outer tub 23, 24 may completely surround the inner tub 25, but when the support 20 moves in the upward direction and thus the length of the support 20 increases, the outer tub 23, 24 does not completely surround the inner tub 25. A combining panel 27 to combine the support 20 with the base 30 is combined with the lower end of the inner tub 25. The combining part 32a of the lower housing 32 and the combining panel 27 of the support 20 are combined with each other through fastening members (not shown).
A height adjustment configured to adjust the height of the support 20 may be located within the inner tub 25. The height adjustment may adjust the height of the support 20 using a gas cylinder (not shown). A cover member 26 may be located at the outside of the gas cylinder (not shown). The cover member 26 may be inserted into the inner tub 25 along grooves 26a formed on the surface of the cover member 26, and thus be moved in the downward direction or the upward direction. In order to guide movement of the cover member 26, ribs (not shown) having a shape which corresponds to the shape of the grooves 26a may be provided on the inner surface of the inner tub 25.
Accordingly, in response to a user desiring to move the display main body 10 in the downward direction, the gas cylinder (not shown) is compressed and the cover member 26 slides along the inner tub 25 in the downward direction. When the user stops movement of the display main body 10 at a desired position, the user may fix the support 20 using the locking mechanism 40.
One side of the support 20 may be extended to the head part 21 with which the display main body 10 is combined. The head part 21 may include a front panel 21a, a rear panel 21c, and a guide panel 21b with which the support 20 is combined. The guide panel 21b may be combined with the front panel 21a, and then, the rear panel 21c may be combined with the front panel 21a through fastening members 22. Since the guide panel 21b protrudes upward from the rear panel 21c, the support 20 may be combined with the guide panel 21b after combination of the rear panel 21c with the front panel 21a. 
The locking mechanism 40 configured to fix the support 20, may be located at one side of the support 20. The locking mechanism 40 may include a locking body part 41 combined with the support 20, and an operation member 42 combined with the locking body part 41 and fixing the locking mechanism 40. The locking mechanism 40 will be described later. A movable part 25a may be located at a portion of the inner tub 25 contacting the locking mechanism 40. In more detail, the movable part 25a is located at a portion of the inner tub 25 contacting the operation member 42, and in accordance with one exemplary embodiment, the movable part 25a is formed by cutting a portion of the surface of the inner tub 25 and may thus have a some degree of movability.
FIG. 5 is a view which illustrates the locking mechanism in the combined state in accordance with an exemplary embodiment, FIG. 6 is a view which illustrates the locking mechanism in the released state in accordance with an exemplary embodiment, FIG. 7 is a cross-sectional view which illustrates the locking mechanism in the combined state in accordance with an exemplary embodiment, and FIG. 8 is a cross-sectional view which illustrates the locking mechanism in the released state in accordance with an exemplary embodiment.
As shown in FIGS. 5 to 8, the locking body part 41 is provided in a ring shape and thus that the support 20 is inserted into the ring-shaped locking body part 41, but the shape of the locking body part 41 is not limited thereto. At least a portion of the locking body part 41 with which the operation member 42 is combined may include an opening 41a (FIG. 6). The opening 41a allows the operation member 42 to press the inner tub 25 with which the locking body part 41 is combined. Since the locking mechanism 40 is combined with one side of the inner tub 25 and the movable part 25a is provided on the surface of the inner tub 25 at the position at which the locking 40 is located, the locking 40 may fix the height adjustment by effectively pressing the gas cylinder (not shown) within the inner tub 25.
The movable part 25a may be provided by cutting the surface of the inner tub 25. Since the movable part 25a is formed by cutting a designated portion of the surface of the inner tub 25, the movable part 25a may have more than a designated degree of movability. Further, an elastic member 25b may be located at the inside of the movable part 25a. The elastic member 25b provided at the inside of the movable part 25a presses the gas cylinder (not shown) located within the inner tub 25 when the locking mechanism 40 fixes the support 20, and movement of the gas cylinder (not shown) may be stopped due to friction between the gas cylinder (not shown) and the elastic member 25b. Further, the elastic member 25b may absorb shock due to contact with the gas cylinder (not shown). The elastic member 25b may be formed of a flexible material, for example, rubber.
The locking mechanism 40 may include the operation member 42 operated by a user to fix the height adjustment. The operation member 42 may be hinged to the locking body part 41 so as to be rotated relative to the locking body part 41. The locking body part 41 includes hinge combining parts 43 with which the operation member 42 is combined, and the hinge combining parts 43 and a fastening hole 42c of the operation member 42 are combined through a rotary pin 44.
The operation member 42 includes a first operation part 42a combined with the surface of the locking body part 41, and a second operation part 42b combined with the surface of the inner tub 25. The second operation part 42b may be provided in a shape, a portion of which is protruded, and such a shape serves to guide pressing of the inner tub 25. The second operation part 42b may press one side of the movable part 25a provided on the surface of the inner tub 25, and the elastic member 25b located on the other side of the movable part 25a may press the gas cylinder (not shown).
FIG. 9 is a perspective view which illustrates the rear surface of a terminal in accordance with another exemplary embodiment, and FIG. 10 is an enlarged view of a fixing mechanism in accordance with an exemplary embodiment.
As shown in FIGS. 9 and 10, a terminal 100 in accordance with this exemplary embodiment may further include a fixing mechanism 60. Hereinafter, some parts in this embodiment which are substantially the same as those in the previous exemplary embodiment shown in FIGS. 1 to 8 are denoted by the same reference numerals even though they are depicted in different drawings, and a detailed description thereof will thus be omitted because it is considered to be unnecessary. A connection member (not shown) connecting the display main body 10 and the base 30 may be provided, and the fixing mechanism 60 serves to fix such a connection member (not shown).
The fixing mechanism 60 may include a fixing unit body part 61 combined with the support 20, and a holder part 62 extended from the fixing body part 61 to fix the connection member (not shown). The fixing body part 61 may be provided in a ring shape, and may thus be combined with the support 20 such that the support 20 is inserted into the ring-shaped fixing body part 61. The holder part 62 is extended from the fixing body part 61. The holder part 62 may be separated from the fixing body part 61 by a designated interval. Therefore, the connection member (not shown) may be inserted into a receiving part 63 provided between the holder part 62 and the fixing body part 61. In order to receive various connection members (not shown) having different thicknesses, the fixing mechanism 60 may be formed of a flexible material. Thereby, the connection member (not shown) which may sag between the display main body 10 and the base 30 is arranged properly, and thus user convenience may be improved In addition, the terminal 100 may have a pleasing external appearance to a user.
As is apparent from the above description, a display device and a terminal having the same in accordance with an exemplary embodiment may increase combining forces between a support and a base and may use the same support and base in main bodies having various sizes, thus simplifying the manufacturing process and reducing the cost of parts and assembly.
Although a few exemplary embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
