ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application entitled Monitor Having Rotary Type Control Box earlier filed in the Korean Industrial Property Office on May 17, 1999, and there duly assigned Serial No. 99-17652 by that Office.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a rotary type control box for a monitor. In particular, the present invention relates to a rotary type control box for a monitor which is rotatably installed at a front surface of a monitor, thereby preventing any interference while accessing the function keys.
2. Description of the Background Art
Conventional monitors include function buttons to control the display properties such as vertical hold, horizontal hold and power. The location of such function buttons has been a problem. Too many function buttons in the front section of a monitor may be convenient, however, aesthetically unappealing. Furthermore, accidentally hitting one of the important function buttons may cause the monitor to display poorly. To selectively hide such buttons, different methods have been used.
For example, Yau (U.S. Pat. No. 5,623,393, Monitor control panel mounting structrue, Apr. 22, 1997) concerns a monitor control panel mounting structure which includes a control panel pivoted to the housing of a monitor. In the Yau patent, the function button structure protrudes when the function buttons are accessed. There may be interference with objects near the monitor's control panel when accessing the function keys.
Lee (U.S. Pat. No. 5,925,860, Rotary control device, and electronic apparatus using it, Jul. 20, 1999) concerns a rotary control device and an electronic apparatus in which it is used. The switches are disposed along the flat circumference of the switch plate. Only a portion of the switch plate is seen at one time. As the cylindrical switch plate is rotated, different function keys are exposed. Lee's patent does not allow a user to view all the function keys at one time. Rotation of the switch plate is necessary. The small space given for function key entry makes it difficult for users with large or arthritic fingers.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a rotary type control box for a monitor which is capable of preventing any interference with certain objects near a monitor. A rotary type control box having various function keys and mounted on a front surface of the monitor is not protruding to the outside of the front casing when operating the function keys and therefore not interfering with any external objects near the monitor.
It is another object of the present invention to provide a monitor having a rotary type control box which is capable of decreasing the number of parts of the control box. The decreased number of parts will decrease the fabrication and maintenance cost.
It is another object of the invention to provide dust protection for the function keys and the internal monitor components.
It is another object of the invention to provide an ease of use coupled with an ability to hide or show the function keys for aesthetics.
To achieve the above described objects, there is provided a rotary type control box for a monitor which includes a rotary type control box rotatably engaging the front casing and having the function buttons formed at an outer surface of the rotary type control box. A boss is formed on an outer surface of the control box at a side opposite to the function buttons for hiding the interior of the monitor for thereby enhancing an outer look of the monitor. Furthermore, there is a stopper formed at the front casing and contacting with the boss when rotating the control box for limiting a rotation of the control box at a certain angle.
In the present invention, the cross-section of the rotary type control box is circular. Pivot pins are protruding from both surfaces of the rotary type control box and are rotatably inserted into an engaging groove of the front casing and are rotatable in the clockwise and counterclockwise directions.
The present invention's rotary design prevents any monitor parts from protruding. Therefore, the control box does not interfere with any external items. The present invention also has a limited set of parts, therefore reducing fabrication and maintenance cost. The rotating design protects the function keys from dust. Furthermore, the exposure of the internal parts of the monitor is prevented by a boss on the control box. The present invention is easy to use in that all the key functions are aligned and shown at the same time. The area used to pressing the function keys is the same as if they were mounted directly to the front casing of the monitor. Users are not limited by their finger size or dexterity. The rotational design allows a user to aesthetically hide the function keys when needed or show all of the keys when needed.
Additional advantages, objects and features of the invention will become more apparent from the description which follows.
