[0003] 2. Description of the Related Art

[0004] Due to higher income resulted from flourishing economy, golf is no longer a luxury sport in recent years. It is widely known that a good golfer needs sophisticated ball-striking skills. For a golf beginner, in addition to practice swings at a driving range, he may hire a coach to improve his skills faster. However, it is expensive to hire a coach. Further, a suitable coach might not always be available. Thus, it is indeed expected by golf lovers to see a mechanical device that is able to instruct golfers and enhance their skill. The current golf instruction machines usually take a passive approach to correct swing postures but not an active approach to teach students proper sequences of motions. Therefore, what could be achieved from these lessons is very limited. Based on many years experience in related fields, the inventor has been persistently devoted to researches and experiments and finally proposes the present invention to provide an improved mechanical golf instruction device and promote the learning efficiency thereof.

[0005] The primary objective of the present invention is to provide an active golf instruction system, which is easy to operate and able to give correct instructions of golf.

[0006] The active golf instruction system of the present invention comprises a first main unit, a second main unit and a computer. The first main unit further comprises three lifting mechanisms and three sliding mechanisms respectively connected to the lifting mechanisms, wherein positioning shafts are respectively installed in the sliding mechanisms and protrude outward from the first main unit. The second main unit further comprises a rotating wheel and a fastening unit installed on the rotating wheel. The first main unit and the second main unit are arranged oppositely, and a student stands in between the first main unit and the second main unit. The computer controls the positioning shafts to contact the head, shoulders, waist and knees of the student according to the height, weight, etc., of the student. A golf club is placed on the fastening unit of the second main unit. Then, the sliding mechanisms and the rotating wheel respectively rotate by appropriate degrees to provide a proper golf swing lesson.

[0007] In one embodiment of the present invention, the lifting mechanism has a mechanical device clamped by two racks. The mechanical device has a motor. A shaft of the motor meshes with two gears. The two gears mesh with the two racks. Then, forwarding or reversing rotation of the motor drives the two gears and enables the mechanical device to ascend or descend along the two racks.

[0008] In one embodiment of the present invention, the sliding mechanism is pivotally coupled to the lifting mechanism. The sliding mechanism has two box units at two ends thereof. Each box unit has a motor. Then, forwarding or reversing rotation of the motor drives the box unit to move leftward or rightward along the sliding mechanism.

[0009] In one embodiment of the present invention, each box unit has two arc-shape plates mutually crossing. Each arc-shape plate has a slot. Each of the positioning shafts penetrates the slots of two mutually-crossing arc-shape plates to obtain degrees of rotational freedom and rotate by various degrees of angles.

[0010] In one embodiment of the present invention, the rotating wheel of the second main unit is pivotally coupled to a motor and driven to rotate by the motor. The fastening unit is a clamping device made of soft material and used to clamp the head of a golf club.

[0018] Referring to FIGS. 1 to 6. The active golf instruction system of the present invention comprises the first main unit 1 and the second main unit 2. The first main unit 1 further comprises a top shaft 11, three lifting mechanisms 3 and three sliding mechanisms 4 respectively connected to the lifting mechanisms 3, wherein positioning shafts 5 are respectively installed in the sliding mechanisms 4 and protrude outward from the first main unit 1. The second main unit 2 further comprises a rotating wheel 21, a fastening unit 22 installed on the rotating wheel 21, and a computer 6 as shown in FIG. 1 and FIG. 6.

[0019] As shown in FIG. 2, the lifting mechanism 3 has a mechanical device 32 clamped by two racks 31. The mechanical device 32 has a motor 33. A shaft 34 of the motor 33 meshes with two gears 35. The two gears 35 mesh with the two racks 31. Then, forward or reverse rotation of the motor 33 drives the two gears 35 and enables the mechanical device 32 to ascend or descend along the two racks 31.

[0020] As shown in FIG. 3 and FIG. 4, the sliding mechanism 4 is pivotally coupled to the lifting mechanism 3. The sliding mechanism 4 is an arc-shape rod and has two box units 41 at two ends thereof. Each box unit 41 has a motor 411. Then, forward or reverse rotation of the motor 411 drives the box unit 41 to move leftward or rightward along the sliding mechanism 4. Each box unit 41 has two arc-shape plates 42 mutually crossing. Each arc-shape plate has 42 and a slot 421. Each of the positioning shafts 5 penetrates the slots 421 of two mutually-crossing arc-shape plates 42 to obtain degrees of rotational freedom and rotate by various degrees of angles.

[0021] Air bags 51 are installed on tips of the positioning shafts 5.

[0022] The rotating wheel 21 of the second main unit 2 is pivotally coupled to a motor 23 and driven to rotate by the motor 23. The fastening unit 22 is a clamping device made of soft material and used to clamp the head of a golf club.

[0023] The first main unit 1 and the second main unit 2 are arranged oppositely, and a student stands in between the first main unit 1 and the second main unit 2. The computer 6 controls the top shaft 11 and the positioning shafts 5 to contact the head, shoulders, waist and knees of the student according to the height, weight, etc., of the student. A golf club is placed on the fastening unit 22 of the second main unit 2. Then, the sliding mechanisms 4 and the rotating wheel 21 respectively rotate by appropriate degrees to provide a proper golf swing lesson.

[0024] Referring to FIGS. 5 to 8. In the application, the first main unit 1 and the second main unit 2 are arranged oppositely, and a student stands in between the first main unit 1 and the second main unit 2. First, the height, weight, etc., of the student are input into the computer 6. According to the data, the program in the computer 6 instructs the lifting mechanisms 3 of the first main unit 1 to control the altitudes of the top shaft II and the positioning shafts 5 to make the inflated air bags 51 respectively contact the head, shoulders, waist, knees, etc., of the student. A golf club 7 held by the student is placed on the fastening unit 22 of the second main unit 2. The instruction program in the computer 6 controls the box units 41 to take arc-shape displacements of appropriate degrees along the sliding mechanisms 4. The positioning shafts 5 drive shoulders, waist, knees, etc., of the student to take rotational motions. At the same time, the computer 6 instructs the motor 23 of the second main unit 2 to drive the rotating wheel 21 to rotate, and the rotating wheel 21 further takes the golf club 7 to move. Then, a proper swing instruction is thus formed by the golf club motion conducted by the second main unit 2 and the body region motions conducted by the first main unit 1.

[0025] Referring to FIG. 9, in the application, the positioning shafts 5 of the first main unit 1 can lead the related body regions to perform a correct swing motion. The computer 6 can regulate the speeds of the positioning shafts 5 to correct the postures of the related body regions step by step. Thereby, the student will learn a correct swing motion finally.

[0026] In conclusion, the present invention proposes an active golf instruction system, which comprises a plurality of positioning shafts and a rotating wheel, and which cooperates with a computer program to undertake golf training, whereby the swing exercise becomes more convenient, and the effectiveness thereof is promoted. The present invention at least has the following advantages:

• [0027] 1. Best swing postures for different swing speeds have been saved in the computer;
• [0028] 2. After the user inputs the intended swing training, the present invention will actively take the head, shoulders, waist, knees, and wrists to exercise the related postures and motions repeatedly, whereby the muscles can memorize the correct swing postures and motions;
• [0029] 3. The present invention overcomes the conventional problem that the training equipments available on the market today still require users to practice swing autonomously with the speeds, angles and postures of the swing motions lacking consistency and correctness, which results in vague or incorrect muscle memory; and
• [0030] 4. The present invention is particularly suitable for a golf beginner because it can make the muscles of the beginner memorize the most correct postures and motions from the very beginning of learning golf.

[0031] Further, the present invention is also suitable for a profession player. When a profession player has a bias in his motions, he can use the present invention to exercise repeatedly until he restores the standard motions.

[0032] From the above description, it is known that the present invention possesses novelty and non-obviousness and meets the condition for a patent. Thus, the Inventor files the application for a patent. It will be appreciated if the patent is approved fast.
