Benefits of technology
[0010] Accordingly, the present invention is conceived to solve the aforementioned problems. It is an object of the present invention to provide an apparatus for measuring golf club swing speed wherein a transmitting device for transmitting an optical signal and a receiving device for receiving the optical signal are separately installed and can be easily installed and used in accordance with a variety of user's necessity and installation positions.
Problems solved by technology
However, the related art apparatus for measuring golf club swing speed has several problems.
First, in a case where a means for measuring golf club swing speed is included in a golf club itself, there is inconvenience in that a user should possess a golf club mounted with such a means.
In particular, if the practice golf club is different from a golf club used in an actual golf game in the field in view of their weights, structures or the like, there may be a problem in that its swing feeling is different from that of a club used in the field.
Second, in a case where golf club swing speed is measured using additional sensors which are not installed in the golf club, it is inconvenient or impossible to measure swing speed due to their installation positions and structures.
For example, since the reflection angle of the signal is not uniform in a structure in which a signal is vertically transmitted from the ground and the signal reflected from the club head of the golf club is then sensed, it is very difficult to sense the reflected signal and it is also highly possible for the structure to erroneously operate.
Further, since the apparatus for measuring swing speed is large and used in a fixed mode in a structure in which an optical signal transmitted from a sensor installed on the ground is blocked by a golf club, it is difficult to adjust the installation position when the apparatus is installed.
Thus, it is inconvenient to actually use the apparatus.
That is, since an apparatus using a related art sensor is configured such that a sensor is physically fixed, there are problems in that a user can use the apparatus at a fixed place and it is very inconvenient to install and use the apparatus.
Accordingly, the apparatus is not practical.
Furthermore, in case of an apparatus in which signal transmitting and receiving parts are integrally formed with each other, a portion adjacent to a hitting point may be easily damaged and a position where a golf ball is actually placed cannot be changed.
Therefore, the apparatus cannot be properly employed in a variety of user's practice circumstances.

Embodiment Construction
[0025] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0026] Referring to FIG. 1, an apparatus 10 for measuring golf club swing speed (hereinafter, referred to as “swing speed measuring apparatus”) comprises a transmitting device 21 and a receiving device 22. The transmitting and receiving devices 21 and 22 are separately installed in the swing speed measuring apparatus 10. The transmitting device 21 sends a plurality of optical signals 4 and 5, and the receiving device 22 receives the optical signals 4 and 5.
[0027] A user 1 can install the swing speed measuring apparatus 10 and measure the If club swing speed at any time and place. That is, if the user swings a golf club 2, the head of the golf club passes between the transmitting and receiving devices 21 and 22. Then, the receiving device 22 senses a state where the optical signals 4 and 5 are blocked by the club head, and the swing speed is aut...

The present invention relates to an apparatus for measuring golf club swing speed. The swing speed measuring apparatus automatically indicates golf club swing speed by detecting a state where optical signals, such as infrared rays, output from a transmitting device thereof are blocked by a golf club. To this end, a receiving device of the swing speed measuring apparatus calculates the golf club swing speed by dividing a distance between the optical signals by a time interval taken between when the optical signals are blocked, and outputs the calculated swing speed. In particular, the transmitting and receiving devices are manufactured as separate devices. The present invention is configured such that a meaningless swing motion such as a case where a user slowly swings the golf club around the ball to take a proper stance or posture can be excluded and an actual swing motion can be distinguished accordingly.
Description
CROSS-REFERENCE TO RELATED APPLICATION(S) [0001] The present application claims priority from Korean Patent Application No. 2004-55680 filed on Jul. 16, 2004. [0002] 1. Field of the Invention [0003] The present invention relates to an apparatus for measuring golf club swing speed, and more particularly, to an apparatus for measuring golf club swing speed wherein a transmitting device for transmitting an optical signal and a receiving device for receiving the optical signal are separately installed and golf club swing speed can be automatically displayed by detecting a state where the optical signal such as an infrared ray signal is blocked by a golf club. [0004] 2. Description of the Prior Art [0005] As golf has become popular, a number of apparatuses capable of allowing a golfer to simply practice playing golf have been developed. Among these apparatuses, there is an apparatus for correcting golfer's swing posture or an apparatus for measuring swing speed and then notifying the spe...
