Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a golf swing practice club, in which it is possible to practice a swing swing while confirming whether or not the player is swinging in the correct form by checking the trajectory of the light without actually hitting the ball. It relates to a golf swing trainer with an improved structure.

[0002]

[Prior Art]

 Conventionally, the practice of swinging without actually hitting the ball on the head of the golf club has been to practice the swing of a normal golf club or a golf swing practice device that has a light emitting part at the tip and grip of the club shaft. There is a way to practice practicing using. In this golf swing practice club, as shown in FIG. 11, a light emitting portion 52 such as a light bulb is coupled to a tip portion 51a of a shaft 51, and a light emitting portion 53 is also formed in a grip portion 51b to form a hollow portion. Electric power is supplied from a battery built in the shaft 51, and a switch structure 54 arranged at an appropriate position of the shaft 51 is operated to turn on or off the light sources of the light emitting units 52 and 53. Then, according to the golf swing practice device configured as described above, as shown in FIG. 12, the light emitting portions 52 formed in the tip portion 51a, that is, the tip portion 51a corresponding to the club head portion and the grip portion 51b, Since the trajectory of light is generated by 53, it is possible to know from the trajectory of the light whether or not the practitioner is swinging the club accurately.

[0003]

[Problems to be solved by the device]

 However, in the conventional golf swing practice device, since the socket of the light bulb that becomes the light emitting portion 52 is press-fitted and fixed to the tip portion 51a of the thin shaft 51 and the grip portion 51b, centrifugal force during the swing is applied. There is a problem that the light emitting portion 52 on the side of the tip portion 51a is easily dropped from the shaft 51 and is very dangerous. In addition, since the switch structure 54 is provided on the outer peripheral portion of the thin shaft 51 and the circuit structure is configured, the manufacturing workability is poor, and especially when the wiring to the light emitting portions 52 and 53 is repeated practicing swinging. It had a problem that it was inferiorly broken and was prone to failure.

The present invention has been made in view of the above problems, and has a simple structure in which a light emitting portion and a switch structure are integrated, does not fall off the shaft, and is easy to assemble. It is intended to provide an excellent golf swing trainer.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a golf swing training device according to the present invention is a golf swing training device having a light emitting part formed on a grip side and a tip side of a shaft, respectively. A light source is housed at one end of a cylindrical housing containing circuit components such as a printed circuit board, and the other side is screwed and connected to the shaft. The operation part is exposed and covered with a cover member.The light emitting part on the tip side accommodates the light source at one end of a cylindrical housing containing circuit components such as a printed board and the other. Side is screwed to the shaft, and the light source can be turned on or off by operating the switch of the light emitting section on the grip side. It is an effect.

[0006]

[Action]

 According to the above configuration, since the housing containing the light source serving as the light emitting portion is screwed and connected to the shaft, even if a centrifugal force is applied to the housing when practicing swing, the housing can be easily separated from the shaft. It does not fall out. In addition, since the housing is formed by integrating the switch structure and the light source, the light emitting part and the switch structure can be easily assembled to the shaft, and when the housing is screwed and connected to the shaft. Electrical connection can be easily made only by bringing the electrode of the switch structure into contact with the electrode of the battery built in the shaft.

In addition, a substantially rectangular notch 25 (see FIG. 6) is formed on the side surface of the shaft 1 at a position where the electrodes C1 and C2 of two or more batteries C, C ... Inserted therein are located. is there. A switch plate 26 made of an insulating material is removably fitted into the shaft 1 through the notch 25 to separate the electrodes C1 and C2 of the two batteries C and C which are connected to each other in an ON state from each other. It is configured to maintain the OFF state. Reference numeral 27 is a cylindrical housing. The structure of the housing 27 is substantially the same as that of the first embodiment, and the light source 5 such as a light emitting diode is housed at one end thereof, and the circuit component 8 such as a printed board and the electrode 18 are formed inside. It has a partition plate 17 and a built-in register.
