Description

Golf swing training device TECHNICAL FIELD

[0001] Golf swing training device BACKGROUND

[0002] Golf is to hit the ball by the body rotation and the body weight translation to the target, the swing of the body when rotating, will produce energy waste, make the hitting distance shorter, and the hitting is not solid, the body weight also needs to be translated to the target to hit the ball when rotating, the direction of the translation is wrong, the hitting direction is wrong. The swing plane also needs to be correct, if the swing plane is inside or outside, the curve ball will be produced. The club head needs to be released to concentrate the energy, so the ball can be hit far, so the swing action and the club plane have a great influence on the golf performance, but it is difficult to make a standard swing action, because it is difficult for the player to adjust the subtle action and the shaft position when hitting the ball with great force, and the action to be modified is often forgotten after training for a period of time, the coach needs to remind, which causes the waste of energy and the increase of the cost of learning golf, especially for some teenagers, it becomes more difficult and loses interest, a special device is needed to guide the body swing action and the swing plane, so that the learning action becomes easy, and the player can train himself, which reduces the burden of the coach and the cost of learning golf, but the existing golf swing training device has many deficiencies, such as only controlling the body action in a certain range, the shaft rotation is not accurate enough, and the action and the swing plane cannot be corrected in time during the swing, the action is often modified, and the hitting action changes again, the effect is not good, a training device is needed to accurately guide the body shaft rotation and the weight translation, guide the club swing plane position, and modify the action at the same time when hitting the ball, which improves the performance of the player. TECHNICAL PROBLEM

[0003] The existing device helps the golfer, but there are still some problems that are not perfect

[0004] Some devices only control the waist to move in a certain range of rail, cannot fix the body shaft angle, the body will swing when rotating, the hitting is not accurate, and the distance is short.

[0005] Some devices only fix the head to rotate, the head and the body weight cannot be translated, lack of body translation energy, and the hitting distance is short.

[0006] Some devices control the arm or the shaft to move in a ring plane, but the main power source, the trunk position action, cannot be guided and corrected, and the body shaft swings.

[0007] Some devices can only control one direction of the club upper shaft plane to prevent inside or outside, cannot prevent at the same time, and cannot control the accurate swing plane.

[0008] The existing device cannot control the body axis swing, correct the body center of gravity movement direction, guide the golfer to delay release, control the swing plane and the ball hitting training of five actions

[0009] The existing device cannot correct the full swing, the split swing, the cut swing and the push swing. Technical solutions

[0010] By fixing the head and waist on the U-shaped rack, the trunk rack assembly (Figure 7) 88 is formed, the angle and position of the trunk rack assembly (Figure 7) 88 are adjusted, the position and posture of the head, shoulder, waist and hip are fixed, the height and position of the trunk rack assembly (Figure 7) 88 are adjusted, the position and posture of the leg are fixed, and the body posture position can be accurately controlled.

[0011] The head fixator (Figure 5) and the waist fixator (Figure 6) are equipped with bearings, the centers of the bearings are coincided, as shown in (Figure 4) 89, the rotation axes of the head, shoulder, waist and hip are concentric, and the body swing is prevented.

[0012] The trunk rack assembly (Figure 7) 88 is equipped with four sliding bearings 15, 16, 21 and 22, the body center of gravity and the trunk rack assembly 88 can slide left and right together in the direction of hitting the ball, and the body rotation and translation in the target direction can be realized.

[0013] The upper rod guide is guided by two guide rails (Figure 14) 112, which can prevent the ball from being hit outside and prevent the ball from being hit inside.

[0014] The upper rod guide is placed in the middle of the upper rod track and the lower rod track (Figure 11), which can guide the upper rod and does not affect the lower rod, so as to force the golfer to delay release.

[0015] Because only the head and the waist are fixed by the fixing belt, the restriction on the body is small, so the body axis swing, the correction of the body center of gravity movement direction, the guidance of the golfer to delay release, the control of the swing plane and the ball hitting training can be realized.

[0016] Multiple adjustment knobs and telescopic rods are designed to adjust the full swing, split swing, cut swing and push swing, which is suitable for various heights and arm lengths. Beneficial effects

[0017] Because the head and the waist have a common fixed axis of rotation and do not swing, the energy loss is small, the power is easy to release, and the golfer hits the ball far.

[0018] The body rotation axis is fixed, the distance between the body and the ball is stable, and the golfer hits the ball accurately.

[0019] The trunk frame assembly (Fig. 7) 88 and the body center of gravity translate along the sliding bearings (Fig. 9) 21, 22, the target direction is locked, and the ball trajectory direction is accurate.

[0020] The swing plane is stable, and the golfer can avoid hitting left and right curves.

[0021] The release is delayed, the energy is concentrated, and the golfer's hitting distance is increased.

[0022] It is simple and easy to use, the action is fixed, and there is no need to understand the action, no need for a coach to remind, and the energy loss and the cost of learning golf of the golfer and the coach are reduced.

[0023] Multiple adjustment knobs and telescopic rods are designed to adjust the full swing, split swing, and push swing, and are suitable for various heights and arm lengths.

[0024] Children can easily learn, such as (Fig. 15) a 5-year-old child can train a beautiful swing action in a few months.

[0025] If the invention is mass-produced and used, more children and adolescents can easily learn golf, fall in love with the sport, enjoy it, and find a solution for enthusiasts who are troubled by swing actions, help athletes to achieve better results, and let more people participate in the healthy golf sport.

[0041] The body trunk swing posture is controlled by the head controller (Figure 5) and the waist controller (Figure 6) controlling the binding of the waist controller. The head controller (Figure 5) fixes the head with the helmet 94 fixed with the belt 95 and the buckle 96, the helmet 94 is connected with the bearing 93 in the center of the helmet 94, and the bearing 93 is connected with the head connecting rod 92 inside. The waist controller (Figure 6) locks the waist with the waist belt 82 locked with the buckle 83, connects the C-shaped waist controller support 81, avoids the rod from hitting the hips, and is designed in a C shape. The C-shaped waist controller support 81 is connected with the bearing 84, and the bearing 84 is connected with the waist connecting rod 85 inside the ring. The bearing 93 allows the head and shoulders to rotate freely along the central axis of the bearing, and the bearing 84 allows the waist and hips to rotate freely along the central axis of the bearing.

[0042] The central axis of the head controller bearing (Figure 4) 93 and the central axis of the waist controller bearing (Figure 4) 84 coincide as the body axis rotation line (Figure 4) 89. The central axis 89 is not perpendicular to the trunk control support 18, but has an angle of about 10 degrees, which is the same as the angle of the spine when the rod is retracted. In this way, the rotation axis of the head, the rotation axis of the shoulder, the rotation axis of the waist, and the rotation axis of the hip all coincide with the central axis 89, which is the rotation axis of the trunk. This axis is controlled by the head controller and the waist controller, so it will not shake during the swing.

[0043] The link between the head controller (Figure 5) and the waist controller (Figure 6) is fixed by the trunk fixing support (Figure 4) 18, 31. Together they form the red part of the U-shaped trunk fixing assembly (Figure 7) 88. The upper trunk control support 18 is inserted into the lower trunk control support 31, locked by the screw locking switch 32, the head controller connecting rod 92 is inserted into the sleeve 17, locked by the screw locking switch 19, and the waist controller connecting rod 85 is inserted into the sleeve 29, locked by the screw locking switch 30. Adjust the length of the head controller connecting rod 92 and the waist controller connecting rod 85 into the sleeve to fit any height of the player, and lock the height position of the head, shoulder and hip after locking the lock knob. The height position of the hips is determined, and the posture of the legs is also determined at the same time.

[0044] The U-shaped body fixing assembly 88 can slide in the sliding shafts (Figure 7) 15, 16, 21, 22 in the direction of the hitting direction. The sliding bearings 22, 21 are connected to the sliding bearing connecting rods 23, 24 respectively, and the sliding bearing connecting rods 23, 24 are inserted into the sleeves 27, 25 respectively, and the sleeves 27, 25 are fixed on the bottom plate 20 and locked by the screw locks 28, 26. The sliding bearings 16, 15 are connected to the sliding bearing connecting rods 11, 8 respectively, and the sliding bearing connecting rods 11, 8 are inserted into the sleeves 9, 7 respectively and locked by the screw locks 10, 6. Adjusting the length of the four sliding bearing connecting rods 23, 24, 11, 8 inserted into the sleeves can accurately control the angle of the torso, and the positions of the head, shoulder and hip are fixed.

[0045] The sleeves 9, 7 are connected to the hinges 11, 1 respectively, and the hinges serve to adjust the change of the angle of the support. The hinges 11, 1 are fixed on the bottom plate 20, and the sleeves 9, 7 are connected to the rotating shafts 14, 5, and the rotating shafts 14, 5 adjust the height of the rods 4, 14 respectively. The rods 4, 14 are inserted into the sleeves 2, 13 respectively and locked by the screw locks 3, 12. The rods serve to support after adjusting the angle of the support. Adding a connecting rod structure between the sliding bearing connecting rods 11, 8 and the sleeves 9, 7 makes the structure more stable, as shown in (Figure 15), there are two horizontal rods to fix the support rods.

[0046] As shown in (Figure 10), it is the swing of the famous athlete McRory. There is a gap between his upper swing trajectory in blue and lower swing trajectory in red. This is because the club head has the largest radius of rotation when swinging up, so the upper swing trajectory in blue is far away from the body. When swinging down, the arms and the shaft keep 90 degrees to delay the release, so the club head is closer to the body, and the lower swing trajectory is closer to the body. There is a gap between the upper swing trajectory in blue and the lower swing trajectory in red, and we use this gap to make a device to guide the upper swing path, as shown in (Figure 11). When swinging up, the club head first passes through the shaft guide to guide the direction of the upper swing, and the position of the upper swing apex is correct. The fixed line between the upper swing apex and the golf ball is the lower swing line, so the whole swing plane is determined. If there is no delay release when swinging down, the lower swing trajectory will be far away from the body, and the club head will hit the shaft guide, forcing the player to delay the release. Of course, the training club and the guide are made of rubber material to prevent hitting.

[0047] The guide is formed by two closed tracks and adjusting the direction of the upper swing shaft, as shown in (Figure 14). The upper swing guide (Figure 14) is formed by closed tracks to form upper holes 111, lower holes 110 and middle gaps 112, which are interconnected. When swinging up, the club head first passes through the 110 holes, and the shaft swings in the 112 gap, and then the club head goes out from the upper 111 holes. Because the 112 gap is narrow, the upper swing trajectory is fixed, preventing inside-out and outside-in.

[0048] As (Figure 13) guide rail 59 is connected to the rotating shaft 58, the rotating shaft 58 is connected to the adjusting rod 57, the adjusting rod 57 is inserted into the sleeve 55 and locked by the screw locking switch 56, the handle 54 and the screw rod 60 nut 64 jointly lock the sleeve 55 on the base 51, the handle 53 and the screw rod 61 nut 62 jointly adjust and lock the rail 52 on the base 51. The length of the adjusting rod 57 inserted into the sleeve 55 can adjust the angle of the guide rod to adapt to players of various heights, and can also adjust to adapt to the swing plane of various wood clubs and various iron clubs. The screw rods 60, 61 move in the rail groove of the base 51 to adjust the front and rear position of the swing plane to adapt to the arm length of the player.
