Description

Technical Field

[0001] The present invention belongs to the technical field of windsurfing boards, and in particular relates to a universal joint structure of a windsurfing board. Background Art

[0002] Influenced by social changes and people's increasingly affluent lives, people are paying more and more attention to leisure sports. Taiwan, China, has rich and diverse coastal terrain and geological landscapes, and clear waters and a good ecological environment have become an important cornerstone for the development of marine water sports in Taiwan, China. In recent years, water sports have evolved from simple water play and swimming to more self-challenging and stimulating surfing and windsurfing. As for windsurfing, a sail is erected on a pedal board using a universal joint. Players stand on the pedal board with their feet and drive against the wind by controlling the direction of the sail. Because of its high sports controllability and entertainment, it is deeply loved by water sports enthusiasts.

[0003] The universal joint of a general windsurfing board is used to allow the sail erected on the pedal float to rotate freely and withstand angle changes, so that players can more flexibly operate the sail to turn, perform skills and manipulate the windsurfing board to improve the fun and performance of surfing. However, the universal joint is often stuck or unable to rotate due to the entry of sand, dirt or other foreign matter in the sea water, and it may also become loose during use, resulting in unstable or unsmooth rotation of the windsurfing board sail. In addition, long-term use and wave impacts can easily cause the universal joint to wear, break or damage, thereby affecting the effectiveness of windsurfing board operation and the safety of exercise. Therefore, the universal joint needs to be maintained regularly, and when problems are found, it needs to be disassembled and maintained immediately.

[0004] The existing universal joint design of windsurfing boards is mainly based on metal ball bearings or springs in the sleeve, which is not only expensive, but also has a certain limit on the angle of rotation and swing. It is also easy to be damaged due to the friction between metal parts of the same hardness. Moreover, it is easy to break due to impact. However, since it is covered in the sleeve, it is not easy to be discovered by the user, which causes troubles in subsequent use. In addition, since it is difficult and time-consuming to disassemble and assemble, it forms a barrier for beginners to enter the field of water sports. Therefore, there is a need for improvement.

[0005] In view of the above shortcomings and needs, the inventor believes that further corrections are necessary. Therefore, with many years of experience in related technologies and product design and manufacturing, he has conducted research and creation on the above shortcomings and actively sought solutions. After continuous efforts in research and trial production, he finally successfully developed a universal joint structure for windsurfing boards, thereby overcoming the troubles and inconveniences caused by the poor design of universal joints of existing windsurfing boards. Summary of the invention

[0006] The main purpose of the present invention is to provide a windsurfing board universal joint structure, by which it is possible to directly identify whether it is broken from the outside, and it can be easily and conveniently disassembled and replaced quickly to improve its practicality.

[0007] Another main purpose of the present invention is to provide a windsurfing board universal joint structure, which can reduce the use of metal parts, not only making the angle of rotation and swinging more flexible, but also reducing the phenomenon of damage caused by mutual wear of parts, and further effectively reducing costs.

[0008] Based on this, the present invention mainly achieves the above-mentioned purpose and its effect through the following technical means, which include: it is applied to a windsurfing board, and a sail is erected on a pedal float. The universal joint is composed of a rubber column and joint seats respectively arranged at both ends of the rubber column;

[0009] The rubber column is a rod-shaped body made of strong rubber, and the rubber column has a long-axis middle column. The rubber column has a mounting head with a larger diameter formed at both ends of the middle column.

[0010] The joint seat is an annular bundle formed by a mounting base frame and a covering frame which are relatively covered, wherein the middle section of the mounting base frame has a first semicircular mounting cavity corresponding to the mounting head and a first semicircular bundle cavity corresponding to the middle column, and the covering frame has a second semicircular mounting cavity corresponding to the first semicircular mounting cavity and a second semicircular bundle cavity corresponding to the first semicircular bundle cavity, so that the mounting base frame and the covering frame can cover the mounting head of the rubber column and the adjacent middle column when they are relatively covered.

[0011] By this, the windsurfing board universal joint structure of the present invention can utilize the design that the mounting heads at both ends of the rubber column body are assembled with the mounting base frame and the covering frame of the joint seat, so that it can be directly identified from the outside whether the rubber column body is broken, and it can be easily and conveniently disassembled and assembled, and can be quickly replaced. At the same time, the use of metal parts can be reduced. Not only can the rotation and swing between the joint seat and the rubber column body of the universal joint be more flexible, but also the phenomenon of damage caused by mutual wear of parts can be reduced, which can further effectively reduce costs, greatly improve its practicality, and further realize its economic benefits.

[0012] The present invention further achieves the aforementioned objectives and effects by using the following technical means; such as:

[0013] The mounting heads at both ends of the rubber cylinder are formed with a convergent conical section on the opposite inner sides, and the first and second semicircular mounting cavities of the mounting base frame and the cover frame of the joint seat form opposite conical sections, so that each joint seat mounting assembly is arranged on the mounting heads at both ends of the rubber cylinder and can rotate axially freely.

[0014] The mounting base frame of the joint seat and the covering frame are respectively formed with an embedding hole and an embedding block on the relative contact surfaces of the covering, and the mounting base frame and the covering frame are jointly provided with a binding ring at the outer side of one end of the middle column corresponding to the rubber column body, which can be quickly disassembled and assembled.

[0015] The tie ring uses at least one locking piece to lock the mounting base frame and the covering frame, so that the mounting base frame and the covering frame of the joint seat can be stably covered on the mounting head of the rubber column.

[0016] A locking hole is formed in the middle of the mounting base frame of the universal joint corresponding to the joint seat of the pedaling floating board, and can be used to selectively lock the pedaling floating board with a locking piece.

[0017] A locking column is formed in the middle of the mounting base frame of the universal joint corresponding to the joint seat of the sail, and can be used for inserting the sail.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention is a universal joint structure for windsurfing boards. In the specific embodiments of the present invention and its components illustrated in the accompanying drawings, all references to front and back, left and right, top and bottom, upper and lower, and horizontal and vertical are only used for convenience of description and are not intended to limit the present invention or its components to any position or spatial direction. The dimensions specified in the drawings and the specification may be changed according to the design and requirements of the present invention without departing from the scope of the invention.

[0028] The structure of the universal joint of the windsurfing board of the present invention is as follows Figure 1 , Figure 2 As shown, it is applied to a windsurfing board, and the universal joint (10) is locked on a pedal board (50) by using a base (55), so that a sail (60) installed upright is inserted by using a truss vertical pipe seat (65), so that the sail (60) on the pedal board (50) can rotate freely and withstand angle changes, so that the player can operate the windsurfing board (50) against the wind by operating the direction of the sail (60);

[0029] And as Figures 2 to 5As shown in the figure, the detailed structure of the universal joint (10) is composed of a rubber column (11) and joint seats (20) respectively arranged at both ends of the rubber column (11). The rubber column (11) is a rod-shaped body made of strong rubber to withstand rotation and impact at different angles and has restoring elasticity. The rubber column (11) has a long-axis-shaped middle column (12), and the rubber column (11) is formed with a mounting head (13) with a larger diameter at both ends of the middle column (12), and the opposite inner sides of each mounting head (13) are respectively formed with a convergent tapered section (15) for each joint seat (20) to be installed and assembled;

[0030] The joint seat (20) is a ring-shaped body that is relatively covered by a mounting base frame (21) and a covering frame (25), wherein the middle section of the mounting base frame (21) has a first semicircular mounting cavity (22) corresponding to the mounting head (13) and the conical section (15) and a first semicircular beam cavity (23) corresponding to the middle column (12), and the covering frame (25) has a second semicircular mounting cavity (26) corresponding to the first semicircular mounting cavity (22) and a second semicircular beam cavity (23) corresponding to the first semicircular beam cavity (24). 7), so that when the mounting base frame (21) and the covering frame (25) are relatively covered, the first and second semicircular mounting cavities (22, 26) can cover the mounting head (13) at one end of the rubber column (11), and the first and second semicircular beam cavities (23, 27) can cover the outer edge of the middle column (12) of the rubber column (11), so that the joint seat (20) can be restricted on the mounting head (13) of the rubber column (11) and can rotate freely in the axial direction. Furthermore, the mounting base frame (21) of the joint seat (20) 1) and the cover frame (25) are respectively formed with an embedding hole (24) and an embedding block (28) that can be relatively embedded on the relative contact surface of the cover frame (25), and the installation base frame (21) and the cover frame (25) are commonly bound with a binding ring (30) at the outer side of one end of the center column (12), and the binding ring (30) uses at least one locking piece (31) to lock the installation base frame (21) and the cover frame (25), so that the installation base frame (21) and the cover frame (25) of the joint seat (20) can be firmly covered on the rubber column body ( 11), and a locking hole (291) is formed in the middle of a mounting base frame (21) of a joint seat (20) of the treading floating board (50) in the universal joint (10), which can be selectively locked on the treading floating board (50) by a locking piece, and a locking column (292) is formed in the middle of a mounting base frame (21) of a joint seat (20) of the sail (60) in the universal joint (10), which can be inserted into a truss vertical pipe seat (65) of the sail (60);

[0031] Thereby, a windsurfing board universal joint structure can be constructed which is easy to assemble and disassemble and can be externally identified as to whether it is broken.

[0032] The windsurfing board universal joint structure of the present invention is as follows in actual operation: Figure 1 , Figure 2 and Figure 5 As shown, in operation, the joint seat (20) at one end of the universal joint (10) is used to be locked on the pedal board (50) by using the base (55), and the joint seat (20) at one end of the locking column (292) in the universal joint (10) can be plugged into the truss vertical pipe seat (65) of the sail (60). In this way, the head (13) installed at both ends of the rubber column (11) of the universal joint (10) and the joint seat (20) can be pivotally connected to provide free rotation of the sail (60) on the pedal board (50). At the same time, the rubber column (11) can be used to withstand angle changes and impacts, so that the player can operate the windsurfing board (50) against the wind by operating the direction of the sail (60);

[0033] Furthermore, since the universal joint (10) uses the joint seat (20) to cover the relative mounting head (13) of the rubber column (11), since it is a contact between a hard material and a soft material, usually only the rubber column (11) will be worn, thereby extending the service life of other parts. Moreover, the rubber column (11) is exposed, so the player can directly identify whether the rubber column (11) is broken or damaged from the outside, and when it needs to be replaced, it only needs to remove the joint seat. By removing the collar (30) of the joint seat (20), the cover frame (25) of the joint seat (20) can be removed, and the rubber column (11) can be quickly separated and taken out, and then a new rubber column (11) can be inserted, and the cover frame (25) can be re-covered and the collar (30) can be locked to complete the replacement, without disassembling the installation base frame (21) of the joint seat (20) connected to the pedal float (50) and the sail (60). The operation is extremely convenient and fast, and even beginners can get started immediately.

[0034] As can be seen from the above description, the windsurfing board universal joint structure of the present invention can utilize the design that the mounting heads (13) at both ends of the rubber column body (11) are covered and assembled with the mounting base frame (21) and the covering frame (25) of the joint seat (20), so that it can be directly identified from the outside whether the rubber column body (11) is broken, and it can be easily and conveniently disassembled and replaced quickly, and at the same time, the use of metal parts can be reduced, which not only makes the rotation and swing between the joint seat (20) of the universal joint (10) and the rubber column body (11) more flexible, but also reduces the phenomenon of damage caused by mutual wear of parts, further effectively reduces costs and improves its practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
