The present invention relates to a level device and a method for displaying leveling, and more particularly, to a level with multiple displaying units for displaying detail data.
A conventional level generally includes a frame with a plurality of level vials connected thereto and each vial receives liquid therein and a bubble formed in the liquid so that the users check the position of the bubble to adjust the objects. Nevertheless, it requires experience to check the position of the bubble, especially for checking an inclined surface. Furthermore, the bubble is not stable and could divide into multiple tiny bubbles which confuse the users to read. Some electronic level devices are developed and display the data by digits which include a range of tolerance.
U.S. Pat. No. 5,594,669, issued on Jan. 14, 1997 discloses an electronic ievel which utilizes two sensors located perpendicular to each other to check two joint surfaces of an object. Digits are displayed on the cruciform scales. However, the electronic level is suitable for leveling two orthogonal surfaces and is not suitable if the two surfaces of the object are not orthogonal to each other. Furthermore, the electronic level cannot display the direction that the surface inclines.
The present invention intends to provide a level and a method for displaying leveling, wherein multiple display units are involved and can be reset for different modes.
The present invention relates to a level includes a display screen with a central area which is located at a center of a cruciform of two groups of horizontal display units and two groups vertical display units and a control portion, and a control portion which includes a mode button (MODE), a reset button (MEMO/SET), a calibration button (CAL) and an alarm set button (SP). A plurality of display bars are located on two sides of each group of horizontal units and arrow-head-shaped horizontal indications are located at two respective remote ends away from the central area of the horizontal display units. The display screen further includes a memory area (Memory), an alarm set area (SP), a calibration area (CAL), a resolution area (Resol), a pitching area (Pitch), and a rolling area (Roll).
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.
Referring to
As shown in
The display screen 20 has a memory area 270 (Memory), an alarm set area 27i (SP), a calibration area 272 (CAL), a resolution area 273 (Resol), a pitching area 274 (Pitch), and a rolling area 275 (Roll). Some portions are displayed by digits or words, such as digits 280 being displayed resolution area 273 (Resol), digits 281 for displaying the pitch and digits 282 for displaying the rolling.
The control portion 30 has a mode button 31 (MODE), a reset button 32 (MEMO/SET), a calibration button 33 (CAL) and an alarm set button 34 (SP).
Referring to
Start 41: switch the power on;
Proceeding the memory 42: the device utilizing the previous memory if no button is pressed, the memory area 270 (Memory) being on;
Setting modes 43: the mode button 31 (MODE) being pressed to set a mode;
Reset 44: pressing the reset button 32 (MEMO/SET) to delete the previous memory and setting the desired mode, or pressing the reset button 32 (MEMO/SET) without using the mode button 31 (MODE) to set zero to the device, the calibration area 272 (CAL) being on, or shutting the power down;
Setting the alarm 45: pressing the alarm set button 34 (SP) to control the alarm in the device and the alarm set area 271 (SP) being on.
The mode setting includes one-dimension mode 46 and two-dimension node 47. The one-dimension mode 46 displays the horizontal display units 22, the display bars 24, the arrow-head-shaped horizontal indications 25 and digits 282 for displaying the rolling. As shown in
The two-dimension mode 47 displays the horizontal display units 22, the vertical display unit 23, surface horizontal indications 26, the pitching area 274 (Pitch), the rolling area 275 (Roll) and digits 281 of the rolling. This data includes two groups of information with three digits for convenience of reference for the users. As shown in
Setting alarm 48: the types or volume of audio of the alarm can be set;
Setting resolution 49: setting resolution of the display screen 20 by pressing the mode button 31 (MODE) and the reset button 32 (MEMO/SET). The digits 280 show the values that to be checked in the resolution area 273 (Resol). This allows the users to check the range to be checked so as to meet different requirements.
The result in the display screen 20 is easily read by displays and the level 12 suggests the directions to be adjusted. By using the resolution setting, the result shows the information of the inclination of the surface to be checked and is helpful to the users to adjust. The alarm allows the level 12 to remind the users about the situations that the surfaces to be checked.
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.
