Abstract
A clubhead measuring gauge comprises a fixed base capable of rotating and adjusting its position along a circumference and fixing a protractor; an adjustable measuring base for mounting the protractor and allowing the protractor to shift its position in an increasing or decreasing angle; and an assistant measuring base having a standard side. All of the foregoing components are coupled to a base having a flat horizontal surface. By means of the protractor of the adjustable measuring base, the face angle of golfclubs can be adjusted to match the measuring angle of the measurement, and thus reducing the error and improving precision. Further, the fixed base is rotated to the left or right to attach the sole of the golfclub with the horizontal surface of the base for the measurement of the angles of golfclubs.
Description
- The present invention relates to a measuring gauge that can improve the precision of the angles measured for clubheads (for woods or irons), and more particularly to a measuring gauge that uses an adjustable measuring base to collocate with an assistant measuring base to measure the lie angle, slope, face angle, and gravity angle of golfclubs with different specifications and sizes than can improve the precision of measurements and reduce errors.
- Most of the present methods used for measuring the angles of golfclubs generally require a tester to hold the golfclub by hand and press the striking face of the clubhead against the measuring gauge, and then the tester determines the angles of the striking face by experience and visual inspection. Such traditional methods of measuring the angles of a striking face of golfclubs can achieve the intended purpose, but the following shortcomings are still found in its practice:
- 1. Since all testers rely on their personal experience to measure angles of a striking face golfclub (regardless woods or irons) in longitudinal and transversal directions and such test is carried out to measure roughly by visual inspection, therefore the measurement and process are not accurate or precise.
- 2. Such a method takes much time and effort for the test, and may even cause defections (since the golfclub is held by hand it is not easy to it steady, therefore, errors in measuring the striking face may occur. As a result, such inaccurate methods cannot achieve the intended effect.
- 3. It is inevitable to have an inaccurate measurement of club angles by visual inspection. Thus, it will affect the striking effect of a golfclub in practice, or even ruin the reputation of the manufacturer.
- In view of the foregoing shortcomings of the prior art, the inventor of the present invention overcame the shortcomings by developing the measuring gauge in accordance with the invention. The features and advantages of this invention are given below:
- 1. The invention uses an adjustable measuring base and an assistant measuring base together to measure angles such as the face angle, lie angle, gravity angle, and sole angle, etc of golfclubs to improve the precision of measurement and maintain quality standards.
- 2. The protractor used in the assistant measuring base of the invention can move along a circumference and align with the groove line of the striking face to improve the precision of measurement and lower the error rate.
- 3. The base for fixing clubheads according to the present invention adopts a screw rod as the axle center, so that the base can rotate left or right along the circumference, and the under side of the clubhead base is parallel to the horizontal base before measuring the angle in order to obtain a more accurate measurement.
- 4. In the measurement according to the invention, the angle measured by the protractor is adjusted to the angle of the measuring clubhead to achieve a corresponding angle measurement, and thus reduce errors.
- The primary objective of the present invention is to overcome the aforementioned shortcomings by providing a clubhead measuring gauge.
