Benefits of technology
"The present invention provides a speed reduction mechanism to a strap supporting post with a winding mechanism for automatically winding a strap. The mechanism includes a rotary member and a stationary member. The rotary member has rubbing bars that are pivoted towards the middle part by tension springs. Centrifugal force will act on the rubbing bars when the winding mechanism functions after the strap has been released from stretched position. The rubbing bars are pivoted towards the stationary member when speed of rotation of the winding mechanism is so high that the centrifugal force is greater than force of the tension springs, thus slowing down rotation of the winding mechanism, and preventing a connecting element from swing too fast too hurt people, which is joined to the free end of the strap."
Problems solved by technology
Consequently, the connecting element 43 will hit the tube-shaped part 44 very hard, and causes loud noise.
And, the connecting element 43 is likely to swing fast, and hits and hurts people near to the post.

A speed reduction mechanism is provided to a strap supporting post having a winding mechanism capable of automatically winding a strap around it; the reduction mechanism includes a rotary member turnable together with the winding mechanism, and a stationary member secured to on top of the post; the rotary member has rubbing bars pivoted to a middle part thereof; the rubbing bars are biased towards the middle part by tension springs; centrifugal force will act on the rubbing bars when the winding mechanism rotates after the strap has been released from stretched position; the rubbing bars are pivoted towards the stationary member when speed of rotation of the winding mechanism is so high that the centrifugal force is greater than force of the tension springs, thus slowing down rotation of the winding mechanism, and preventing the free end of the strap from swing too fast.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a strap supporting post capable of automatically making a strap wound therearound, more particularly one, which is equipped with a reduction mechanism so that the strap won't be wound back around the post too rapidly by the winding mechanism after it has been stretched for use. [0003] 2. Brief Description of the Prior Art [0004] Referring to FIGS. 5, and 6, a conventional strap supporting post 4 is comprised of a post part 41, and a winding member, and has a strap 42 connected thereto. The post part 41 can stand on the ground, and has several securing bars 48 equidistantly spaced on an outer side of an upper end thereof. The winding member is arranged on top of the post part 41, and includes a tube-shaped part 44, a shaft 46, and a return spring 45. The strap 42 is secured to an outer side of the tube-shaped part 44 at a first end, and has a connecting element 43 connected to a secon...
