Description

[0001] The present invention relates to a hybrid golf club measuring apparatus,

The present invention relates to a golf club measuring apparatus, and more particularly, to a hybrid golf club measuring apparatus capable of precisely and easily measuring the length, swing weight, total weight, and frequency of a golf club using one combined type measuring apparatus will be.

In order to fit a golf club to each user's body, a fitting device is required. Most of these fitting equipments are manual, lack accuracy, and measure each characteristic such as frequency, spine, swing weight, total weight and club length The fittings of the golf clubs are required to be purchased separately for the whole fitting of the golf clubs in the fitting shop. In addition, all of these equipments must be purchased, There is a time consuming problem.

Each of the above measuring devices will be briefly described. First, the frequency measuring device is a device for indicating the strength of the shaft in terms of frequency. After fixing the butt and the grip portion of the club, shake the top and bottom to shake the shaft for one minute Which is essential for club fitting work.

These frequency measuring devices are classified into passive type and automatic type, and there are laser type and infrared type sensor depending on the measurement type.

In the passive measuring device, it is necessary to press the club part with a constant force rather than the accuracy of the sensor, and it is an accurate measurement. However, there is a disadvantage in that the accuracy is changed according to the measuring person because the degree of turning the lever for fixing the grip part is different for each person to measure. Also, in case of hydraulic type, there are many peripherals whose pressing accuracy is constant, accuracy of measurement is more accurate than that of manual lever type, use of air compressor causes noise, and measurement error is caused by how hard the head is pressed. do.

In addition, the laser-type measuring device is the only one of Golfsmith of the United States, and the laser method does not have a great advantage other than the infrared ray sensor is not influenced by the sunlight.

Next, the swing weight and total weight measuring device is a device for measuring the total weight of the golf club and the weight (balance) of the club felt on the wrist, that is, the swing weight when gripping the grip. For example, When used, the balance (K) can be obtained as 14 × F when the club is held at a point 14 inches from the grip end of the club and the club applies a balancing force to the end of the grip. Then, the K value is classified into A to F from the light side, and the classification of each major classification is further divided into 10 to 0 to 9, and the weight of the club felt on the wrist, for example, is indicated by E4 when the grip is gripped. Based on this indication, the user can select an optimum balance of golf clubs according to his / her power.

The above-mentioned swing weight and total weight measuring apparatus are mainly made of an analog measuring apparatus in which human readings are measured by reading a scale, and in some fitting industries, there is also a case where a digital balance is converted and used by itself. But it has a disadvantage of large measurement error due to reading by the observer.

On the other hand, since the length of the club is generally measured with a naked eye using a steel ruler or the like, there is also a disadvantage in that there is a large error in each measure.
