1. Field of the Invention

The present invention relates generally to tools of precision measurement, and more particularly to an outside micrometer which accurately and precisely measures either the length, the width, the height, or the diameter of an object. The invention measures any combination of the above. This invention allows a user to make measurements much faster as compared with a wide variety of outside micrometers that are on the market today. The conventional outside micrometers on the market today utilize a rotary thread spindle system whereby the measurement output is decreased. Due to the complex design of the conventional outside micrometers on the market today, it is not easy to take quick and accurate measurements. And therefore, the measuring efficiency has been low.

2. Brief Description of the Related Art

The field of measurements and specifically to micrometers as used by such persons as drafters, contractors, artisans, architects machinists, etc. are used on a daily basis. Tools for providing accurate measurements of outside lengths, widths, diameters, and heights are absolutely necessary for the completion of jobs in these industries.

Contractors, machinists and architects however, must carry a large amount of other tools and supplies with them during jobs to perform necessary tasks. Any of these persons would be enabled to perform their duties more efficiently if measurements are done more rapidly with increased accuracy, thereby lessening fatigue and thereby increasing work quality.

What is needed in the art is a micrometer that allows a user to make measurements much faster and more accurately as compared with a wide variety of outside micrometers that are on the market today. The present invention satisfies those needs.

The present invention relates generally to tools of precision measurements, and more particularly to an outside micrometer which accurately and precisely measures either the length, the width, the height, or the diameter of an object. The invention measures any combination of the above. This invention allows user to make measurement much faster as compared with a wide variety of outside micrometers that are on the market today. The conventional outside micrometers on the market today utilize a rotary thread spindle system whereby the measurement output is decreased. Due to the complex design of the conventional outside micrometers on the market today, it is not easy to take quick and accurate measurements. And therefore, the measuring efficiency has been low.

The disadvantages and limitation of the conventional outside micrometers are overcome by the present invention. With this invention, a user can measure an object much more quickly than any conventional outside micrometer. At the same time, the present invention measures work without loss of accuracy. The present invention incorporates the use of linear spindle motion thereby enabling a much faster and more precise travel from the distance of one end to the distance of the second end of the work being measured as compared with conventional rotary thread spindle motion micrometers that exist on the market today.

The conventional outside micrometers existing on the market also utilize a linear sensor digital gauge, whereby the measuring range is limited to a range between fifteen and twenty millimeters. The present invention incorporates a rotary motion sensor capable of increased measurement speeds of up to ten times that of the conventional outside micrometers. Additionally, the measuring range of the present invention is much greater, and is capable of measuring in the range of up to between zero and 200 millimeters.

Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. Referring to the drawing figures, like reference numerals designate identical or corresponding elements throughout the several figures.

According to principles of the present invention, the present invention accurately and precisely measures either the length, the width, the height, or the diameter of an object—or any combination of the above. This invention allows a user to make measurement much faster as compared with a wide variety of outside micrometers that are on the market today. The conventional outside micrometers on the market today utilize a rotary thread spindle system whereby the measurement output is decreased. Due to the complex design of the conventional outside micrometers on the market today, it is not easy to take quick and accurate measurements. And therefore, the measuring efficiency has been low.

Still other objects, features, and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of embodiments constructed in accordance therewith, taken in conjunction with the accompanying drawings.

The present invention includes the following main parts: Electronic processing and digital display unit ( 5 ), Linear motion digital sensor/scale ( 8 ), Digital/linear scale receiving sensor ( 6 ), Micrometer body ( 20 ), Linear spindle ( 10 ), Micrometer anvil ( 19 ), Spindle retract spring ( 12 ), Linear motion digital sensor/scale base ( 11 ), a Spindle control unit includes ( 1 , 2 , 3 , 4 , 7 , 22 ), and a Spindle linear movement unit includes ( 9 , 10 , 11 , 12 , 13 ).

In a stationary position, by the force created by Spindle retract spring ( 12 ), the Linear spindle ( 10 ) is forced to move to the left, which forces the Linear spindle ( 10 ) and Micrometer anvil ( 19 ) to move close to each other.

By operating the spindle control unit, the Linear spindle ( 10 ) will move to the right which moves away from Micrometer anvil ( 19 ). At the same time, with the movement of the Spindle linear movement unit, Linear motion digital sensor ( 8 ) also moves together with the Spindle linear movement unit. Digital scale receiving sensor ( 6 ) collects data and forwards the data to Electronic processing and digital display unit ( 5 ). Data is then calculated by the Electronic processing and digital display unit ( 5 ), and displays it as readable numerical date.

Thimble handle motion barrel ( 4 ) is mounted on the Micrometer body ( 20 ). The Spindle control unit includes: Thimble handle screw ( 1 ), Thimble handle ( 2 ), Thimble handle motion barrel cover ( 3 ), Thimble handle motion barrel ( 4 ), Thimble handle shift bar ( 22 ), Gearing System ( 23 ), and Thimble handle retractable spring ( 7 ). Thimble handle ( 2 ) and Thimble handle shift bar ( 22 ) and Gearing System ( 23 ), are fixed on and connected by Thimble handle motion barrel cover ( 3 ). Thimble handle motion barrel ( 4 ) is at inside of Thimble handle motion barrel cover ( 3 ). The motion created by the Thimble handle ( 2 ) will make rotary movement on Thimble handle motion barrel ( 4 ). At the same time, the rotary movement of Thimble handle motion barrel ( 4 ) will make Thimble handle shift bar ( 22 ) rotate. Thimble handle retractable spring ( 7 ) is connected to the Thimble handle shift bar ( 22 ), Gearing System ( 23 ), and Linear motion digital scale base ( 11 ). The movement of Thimble handle shift bar ( 22 ) moves Thimble handle retractable spring ( 7 ), and therefore moves the Linear motion digital scale base ( 11 ). The rear part of the Linear spindle ( 10 ) is mounted inside the Linear motion digital scale sensor base ( 11 ). And, Linear motion digital sensor ( 8 ) is mounted on the surface of the Linear motion digital scale sensor base ( 11 ) face toward the Electronic processing and digital display unit ( 5 ). Therefore, with the movement of Linear motion digital scale sensor base ( 11 ), both the Linear spindle ( 10 ) and Linear motion digital sensor ( 8 ) move together to the same direction. Digital scale receiving sensor ( 6 ) collects data and forwards the data to Electronic processing and digital display unit ( 5 ). Data is then calculated by the Electronic processing and digital display unit ( 5 ), and displays it as readable numerical date. When the Thimble handle ( 2 ) is set free, the force created by Spindle retract spring ( 12 ) will move the Linear spindle to its stationary position.

The front portion of the Linear spindle 10 will move through Spindle guide track ( 9 ). A slot on the Linear motion digital scale sensor base ( 11 ) will move through Spindle guide pin ( 14 ). Both the Spindle guide track ( 9 ) and Spindle guide pin ( 14 ) assure the Linear spindle ( 10 ) travel through a linear straight line.

While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.

It will be appreciated by those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restricted. The scope of the invention described by the foregoing includes all changes that come within the meaning, range and equivalence thereof and is intended to be embraced therein.
