Benefits of technology
[0012] The objective of the invention is to offer a bridle device for a surfboard, provided with a flexible rope having its lower end connected with an engage member which has the upper side formed with an arc-shaped projecting surface. A rope-fitting holder is threadably combined with a connecting base provided in a preset portion of a board body. The rope-fitting holder is formed with a center hollow having its upper and lower end respectively formed with a small-diameter and a large-diameter hole, and the small diameter hole has its inner wall formed with an arc-shaped recessed surface. The flexible rope has its lower end and its engage member inserted in the rope fitting holder respectively through the small-diameter and the large-diameter hole, letting the arc-shaped projecting surface of the engage member closely contact with the arc-shaped recessed surface in the inner wall of the small-diameter hole. Thus, the flexible rope and the rope fitting holder can interact to perform three-dimensional (3-D) turning of 360 degrees, having secure combination between the bridle and the board body and enabling the bridle to turn for 360 degrees smoothly and stably.
Problems solved by technology
The tube base 12 of the board body 10 is tied together with the metal rotary head 22 by the nylon rope 25, increasing cost in material and labor, influencing integral beauty and rendering the nylon rope 25 liable to loosen off due to improper tying.

Embodiment Construction
[0022] A preferred embodiment of a bridle device for a surfboard in the present invention, as shown in FIGS. 3 and 4, includes a board body 30 and a bridle 40 combined together.
[0023] The board body 30 has a connecting base 32 installed in a preset portion for connecting and fixing the bridle 40 and a vertical combining hole 31 with a proper shape bored between the topside and the bottom side.
[0024] The bridle 40 consists of a hand strap 41, a flexible rope 42, two engage members 43, a rope holding base 44 and a rope fitting base 45.
[0025] The connecting base 32, as shown in FIG. 5, is composed of a tube base 33 and rod base 34. The tube base 33 is formed with a connecting stud 331 in a lower portion and a flange 332 in an upper end. The tube base 33 further has its upper portion bored with a female-threaded hole 333 with a large diameter and a small female-threaded hole 334 in its lower portion communicating with the large female-threaded hole 333, which has its upper outer circ...

A bridle device for a surfboard includes a flexible rope having its lower end connected with an engage member with an arc-shaped projecting surface. A rope-fitting holder is threadably combined with a connecting base of a board body, having a center hollow. The center hollow has its upper and lower end respectively formed with a small-diameter and a large-diameter hole, the small-diameter hole having its inner wall formed with an arc-shaped recessed surface. The flexible rope has its lower end and its engage member inserted in the rope fitting holder respectively through the small-diameter and the large-diameter hole, letting the arc-shaped projecting surface of the engage member push against the arc-shaped recessed surface in the inner wall of the small-diameter hole. Thus, the flexible rope and the rope-fitting holder can interact to perform three-dimensional turning of 360 degrees.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a bridle device for a surfboard, particularly to one simple and secure in structure, easy to be produced and able to perform three-dimensional turning of 360 degrees smoothly. [0003] 2. Description of the Prior Art [0004] A conventional surfboard, as shown in FIGS. 1 and 2, includes a board body 10 and a bridle 20. The board body 10 has a section inserted therein with a connecting base 13 consisting of a rod base 11 a and tube base 12 and respectively secured on the lower and the upper side of the board body 10. The tube base 12 is provided with a tying hole 121 at the topside. [0005] The bridle 20 is formed with a flexible rope 21 having each end provided with a metal rotary head 22 and a metal rotary base 23, and the metal rotary head 22 is restricted to turn axially with the rotary base 23. The rotary base 23 and the end of the bridle 20 are wrapped with thermoplastic cover 24 molded int...
