Bridle device for a surfboard

Abstract

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.

1 . A bridle device for a surfboard comprising a board body and a bridle, said board body having a connecting base in a preset portion, said bridle formed with a flexible rope, said flexible rope having its opposite ends respectively connected with said connecting base and a hand strap: and characterized by, 
 A rope fitting holder formed with a through center hollow, said center hollow having its upper end formed with a small-diameter hole for the lower end of said flexible rope to be inserted therethrough, said small-diameter hole having its inner wall formed with an arc-shaped recessed surface: and    An engage member connected with the lower end of said flexible rope after said flexible rope is inserted through said small-diameter hole of said rope fitting holder, said engage member having its upper inner side formed with an arc-shaped projecting surface, said arc-shaped projecting surface closely pushing against said arc-shaped recessed surface in the inner wall of said small-diameter hole of said rope fitting holder, said flexible rope able to perform three-dimensional turning of 360 degrees by interaction of said engage member and rope fitting holder.    
   
   
       2 . The bridle device for a surfboard as claimed in  claim 1 , wherein said flexible rope has its upper end connected with an engage member having its lower end formed with an arc-shaped projecting surface, and a tubular rope holding base is formed with a through center hollow having its opposite ends respectively formed with a large-diameter hole and a small-diameter hole, said small-diameter hole having its inner wall formed with an arc-shaped recessed surface, said flexible rope having its upper end inserted through said small-diameter hole, said engage member at the upper end of said flexible rope deposited in said rope holding base through said large-diameter hole, said engage member having said arc-shaped projecting surface closely pushing against said arc-shaped recessed surface in the inner wall of said small-diameter hole, said rope holding base having two symmetrical portions of its outer wall respectively bored with a position slot, a band inserted through said position slots after said rope holding base is wrapped in a preset portion of said hand strap, said band having its opposite ends sewed firmly with said hand strap, said hand strap able to perform three-dimensional turning of 360 degrees by interaction of said rope holding base and said engage member.  
   
   
       3 . The bridle device for a surfboard as claimed in  claim 1 , wherein said engage member is a sphere having a semi-spherical bottom shell and a semi-spherical top cap fitted together, said bottom shell having its outer circumference formed with an arc-shaped projecting surface, said bottom shell bored with a through hole in the center, said flexible rope having its end thermo-fused and formed with a comparatively large head after inserted through said through hole of said bottom shell, said large head at the end of said flexible rope engaged with the inner side of said through hole of said bottom shell.  
   
   
       4 . The bridle device for a surfboard as claimed in  claim 1 , wherein said rope fitting holder has its lower portion formed with a threaded tube having its outer circumference formed with male threads and its upper end extending outer diametrically and forming a comparatively large brim, said threaded tube and said brim formed with a through center hollow, said through hollow portion having its upper end formed with a comparatively small hole and its lower portion formed with a comparatively large hole, said board connecting base comprising a tube base and a rod base threadably combined together, said tube base formed with a connecting stud and a flange formed in an upper portion, and tube base also having its upper end bored with a large female-threaded hole in the center and a small female-threaded hole in said connecting stud, sail small female-threaded hole communicating with said large female-threaded hole, said large female-threaded hole having its outer circumference bored with a position recess, said rope fitting holder threadably connected with said tube base by screwing said male threads of said threaded tube with said large female-threaded hole of said tube base, said brim of said rope fitting holder received in said position recess of said tube base, said rod base formed with a male-threaded shank, said threaded shank having its lower end extending outward diametrically and a flange at its lower end, said flange bored with a groove, said connecting stud of said tube base threadably connected with said threaded shank of said rod base and inserted in a through combining hole bored vertically in a preset portion of said board body, said flange of said tube base and said flange of said rod base respectively and firmly pushing against the upper and the lower side of said board body.
