Description

[Technical field]

[0001] The present invention relates to a training device for use in golf club swing training. [Background technology]

[0002] In order to improve golf scores, various training devices have been developed and are being used, in addition to training the swing of a golf club, driving ranges, and increasing the number of rounds played on the course.

[0003] For example, Patent Document 1 discloses a golf swing training device in which, when the grip of a golf swing mechanism is gripped and a swing is made, the rotation of the grip in an arc is transmitted via a power transmission shaft to which a swing arm fixing holder is fastened as a rotation of a weight arm fixing holder, which fixes a weight arm, about its axis, and the weight of the weight arm acts as an effective load for cultivating swing power, and the golf swing mechanism comprises a straight slide arm, a grip connected to the slide arm, a straight swing arm connected to the head base end of the power transmission shaft, and a sliding member, the slide arm and the swing arm have a common longitudinal direction and are disposed adjacent to each other via the sliding member, and the slide arm slides via the sliding member in the longitudinal direction of the swing arm and along the swing plane in response to the arc movement of the grip along the swing plane from the setup state with the grip gripped to the finish of a golf swing.

[0004] It is said that the use of this device has the following effects: (1) It can strengthen the muscles needed for a golf swing, such as the abdominal muscles, back muscles, side torso muscles, and arm strength. (2) It allows repeated practice of swinging without rising from a leaning forward posture during the swing, and it also allows for muscle training required to maintain a leaning forward posture, stabilizing the swing axis.

[0005] However, the training device disclosed therein is a stationary type, requires a certain amount of space for installation, has a complex structure and has a large number of parts, and there is thought to be room for improvement in terms of cost.

[0006] Patent Document 2 also discloses a golf swing training tool having a shaft made of a flexible material, both ends of the shaft being grip parts to be held with both hands, each grip part being fitted with a grip member, one grip part being heavier than the other grip part, the shaft being made of a flexible material having a cylindrical space, the cylindrical space being filled with a powdered weight member, the heavier grip part being equipped with a metal tubular socket with a bottom that is fitted to one end of the shaft with a predetermined space from the end face, a weight member filled in the space of the tubular socket, and a grip member fitted to the outer periphery of the tubular socket, the total length of which is set so that the shaft crosses the back diagonally at the top position and the finish position of the backswing when a golf swing is performed, and the grip part at the tip can be wrapped around the armpit. The effects obtained by using this training tool are described as being able to master the correct swing and rhythm, and strengthening the muscles necessary for swinging.

[0007] However, the training device disclosed therein has a structure in which powdered weights are sealed in a cylindrical space, and therefore the weight of the weight is limited to a certain range, and the effect is also limited to this range, so it is considered that there is room for improvement.

[0008] [Patent Document 1] Patent No. 5578645 [Patent Document 2] Patent No. 3913740 Summary of the Invention [Problem to be solved by the invention]

[0009] SUMMARY OF THE PRESENT DISCLOSURE In view of the above problems, the present invention provides a golf training device that does not require an installation space, is not limited to a place where it can be used, and is simple and effective. [Means for solving the problem]

[0010] The present inventors have intensively studied the structure of a training device that allows a golf club to be practiced while under load, and as a result have arrived at the present invention.

[0011] In order to solve the above problems, one embodiment of the golf training device of the present invention has a running track shape formed by integrating two straight sections and two semicircular sections, and is characterized by having a handle portion that can be held in the palm of the hand and pinched between the thumb and fingers on one of the straight sections, a rod-shaped member that is joined to the other straight section at an angle of 30° to 60° to the longitudinal direction of the other straight section and has a stopper at its tip, a weight whose overall length is shorter than that of the rod-shaped member and has a through hole at approximately the center that can be loosely fitted into the rod-shaped member, and a compression spring arranged around the rod-shaped member between the weight and the stopper.

[0012] Furthermore, a golf training device according to one aspect of the present invention is characterized in that it has a dummy shaft attached to the handle portion so as to extend in the direction of the side where the stopper is disposed. Effect of the Invention

[0013] The golf training device of the present invention is used by holding a running track-shaped handle with both hands and swinging a golf club, but since it is equipped with a detachable weight, it can be swung with a load on the body. In addition, since the weight moves toward the stopper when the golf training device is swung, the centrifugal force of the golf training device is increased, and training is provided to improve the ability to properly control the swing trajectory of the club.

[0014] In this case, if the weight moves suddenly, it may lead to injuries to the shoulders, elbows, or wrists, so in the golf training equipment of the present invention, a compression spring is placed between the stopper and the weight, which prevents the movement of the weight from causing impact on the body. [Brief description of the drawings]

[0015] [Figure 1] 1A and 1B are diagrams showing an example of a golf training device according to the present invention, in which FIG. 1(a) is a plan view and FIG. 1(b) is a front view. [Diagram 2] 2(a) is an example of a male thread provided on the rod-shaped member, and FIG. 2(b) is an example of a female thread provided on the handle. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows an example of a golf training device according to the present invention, in which Fig. 1(a) is a plan view and Fig. 1(b) is a front view.

[0017] The example shown here has a running track-shaped handle 1 that is an integral part of a straight line with a thickness of about 28 mm and a length of about 130 mm, and a semicircular part with an inner diameter of about 43 mm and an outer diameter of about 100 mm. When using the tool, the upper side in FIG. 1(b) is held by wrapping the straight part with the palms of both hands, forming a finger loop 2. If you are right-handed, you hold the left side in the figure with your left hand and the right side with your right hand. In FIG. 1(a), the state of holding the tool with both hands is shown by dashed lines. The material that constitutes the handle 1 is not particularly limited, but since mechanical strength is required, it is preferable to use a metal such as aluminum or iron.

[0018] 1(b), a dummy shaft 3 is attached via a dummy shaft locking means 4 to the right of the upper straight section, allowing the player to master a proper swing. As the dummy shaft locking means 4, a female screw provided in the handle portion 1 and a screw that screws into the female screw can be used, but is not limited thereto.

[0020] Also, a rod-shaped member 7a is joined to the lower straight portion in FIG. 1(b) in a direction forming an angle θ as shown in the figure, and a weight 5 having a through hole (not shown) at the approximately center is loosely fitted so as to be slidable along the rod-shaped member 7a. FIG. 2 is a diagram showing a joint structure between a handle portion and a rod-shaped member in one example of a golf training device according to the present invention. FIG. 2(a) shows an example in which a male screw 8b is provided on the rod-shaped member 7c and a female screw is provided on the handle member 1a, and FIG. 2(b) shows an example in which a rod-shaped member 7d is inserted into a bottomed hole 10 provided on the handle portion 1b, and a set screw 11 is screwed into the female screw provided on the handle portion 1b to fix the rod-shaped member 7d. With such a structure, by making the rod-shaped member 7a detachable, it becomes possible to replace the weight 5, and a weight of an appropriate weight can be used. The angle θ in the example shown here is approximately 45°. The angle θ is preferably 30° to 60°.

[0021] As described above, a stopper 7b is provided at the end of the rod-shaped member 7a opposite to the handle member 1 side, and a compression spring 6 is disposed between the weight 5 and the stopper 7b to reduce the impact caused by the movement of the weight during the swing. A rubber O-ring is disposed at the contact point between the handle portion 1 and the weight 5, which reduces the impact caused by the collision between the handle portion 1 and the weight 5 when the weight 5 returns to its original position.

[0022] An example of the effect of the golf training device of the present invention is that by starting the swing from a forward leaning posture, feeling the weight of this device, and then using the spine as an axis to rotate the shoulders and pelvis to bounce the weight transfer to the right foot side (for right-handed people) at the top position of the backswing, and then repeatedly practicing the weight transfer to the finish position of the swing, the muscle strength required for the swing is strengthened, and the swing axis and swing trajectory are learned by the body with the best rotation and trajectory due to the weight of this device. Note that the swing at this time is the basic swing of golf.

[0023] As described above, according to the present invention, it is possible to provide a golf training device that is not limited to a specific place of use and has a simple structure. The present invention is not limited to the above-described embodiment, and it goes without saying that the present invention includes any design changes that are conceivable to a person having ordinary knowledge in the field of the present invention, including various modifications and alterations, as long as they do not deviate from the gist of the present invention.
