August 26, 2014



By a News Reporter-Staff News Editor at China Weekly News -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor CHOU, Wen-San (Tainan City, TW), filed on January 21, 2014, was made available online on August 14, 2014.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "A manometer is also called pressure meter or pressure gauge. Currently, conventional manometers can be roughly classified into two categories as electronic type and mechanical type. The electronic manometer typically integrates a pressure sensor and related electronic components to measure and display pressure value measured for example as Taiwan (ROC) patent application in number of TW093124608. Most mechanical manometers are adapted from Bourdon gauge, which basically integrates a Bourdon tube, a pivot with a pivot pin, a lever, a sector gear with gear train, an indicator needle and a hair spring to measure and display pressure value measured for example as Taiwan (ROC) patent application in number of TW088203528. Other mechanical manometers are adapted from diaphragm gauge, which basically integrates a diaphragm, a sliding shaft, sliding cylinder, a helical wire, a spring and an indicator needle to measure and display pressure value measured for example as Taiwan (ROC) patent application in number of TW6510501. However, there are some drawbacks in foregoing conventional manometers. Firstly, for displaying pressure value measured, both of the electronic manometer and mechanical manometer involve too many components with complicated structure. Secondly, for air pressure in the manometer, there is no protective means to keep it in safety range.

"Having realized and addressed drawbacks aforesaid for conventional manometers, the applicant of the present invention works out a simple contrivance of the present invention to solve all the drawbacks aforesaid."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "Accordingly, the primary object of the present invention is to provide a manometer, which comprises a manometer body accommodating a plunger, a cap mount, a primary box spring and an auxiliary box spring. By means of the primary box spring and auxiliary box spring function as overall air pressure reflection in combination of coarse air pressure variation responded by the primary box spring and fine air pressure variation responded by the auxiliary box spring the value of the air pressure can be precisely measured.

"A further object of the present invention is to provide a manometer, which comprises a manometer body of transparent cylinder with an indicating scale with graduated markings of pressure units on the peripheral and an internal cylindrical cavity, a plunger with a tinted O-ring sleeved on an annular groove, a cap mount, a primary box spring and an auxiliary box spring. By means of the tinted O-ring sleeved on the annular groove of the plunger and the indicating scale with graduated markings of pressure units on the manometer body function as indication of air pressure measured, the user can easily read out the measured value of the air pressure.

"Another object of the present invention is to provide a manometer, which comprises a manometer body with a safety vent disposed on the peripheral of manometer body in a selective calibrated position preset by the requirement for the upper safety limit of the air pressure from input compressed air, a plunger with a tinted O-ring sleeved on an annular groove, a cap mount, a primary box spring and an auxiliary box spring. By means of the safety vent disposed on the peripheral of manometer body and the tinted O-ring sleeved on the annular groove of the plunger function as safety proactive means for input compressed air, when the air pressure of input compressed air exceeds the upper safety limit preset for the manometer body, the tinted O-ring sleeved on the annular groove of the plunger will pass the safety vent to let subsequent input compressed air discharge out of the manometer body via the safety vent to disable the movement of the plunger.

"The other object of the present invention is to provide a manometer, which comprises a manometer body with various docking means and anchoring means, a plunger with a tinted O-ring sleeved on an annular groove, a cap mount, a primary box spring and an auxiliary box spring so that it is easily jointed with external air compressor on a trailer, truck or other vehicles.

"The real structure and effects of the present invention for achieving foregoing objects are disclosed in the following preferred exemplary embodiments with related drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

"FIG. 1 is a perspective exploded schematic view showing the first exemplary preferred embodiment for a manometer of the present invention.

"FIG. 2 is a perspective assembled schematic view showing the first exemplary preferred embodiment for a manometer of the present invention.

"FIG. 3 is a cross sectional schematic view showing the first exemplary preferred embodiment for a manometer of the present invention sectioned along the longitudinal axis thereof.

"FIG. 4 is a cross sectional schematic view showing the first exemplary preferred embodiment in operation for a manometer of the present invention sectioned along the longitudinal axis thereof.

"FIG. 5 is an illustrative schematic view showing the first exemplary preferred embodiment for a manometer of the present invention combined with an air compressor.

"FIG. 6 is a schematic view showing the second exemplary preferred embodiment for a modified adaptor for a manometer of the present invention.

"FIG. 7 is a schematic view showing the third exemplary preferred embodiment for another modified adaptor for a manometer of the present invention."
