Description
BACKGROUND OF THE DISCLOSURE
Technical Field

The present disclosure relates to a saddle, and more particularly to the structure of a bicycle saddle.


Description of the Related Art

Bicycle is one of the favorite transportation means with highly convenient, energy-free, pollution-free sports and leisure functions. With the rise of leisure atmosphere in recent years, people pay more and more attention to the quality of leisure life, and bicycle has gradually become more popular and widely used nowadays.


When we ride a bicycle, a saddle is mainly provided to support our body weight. With reference to FIG. 10 for a conventional bicycle saddle, the saddle comes with a tapered cushion body 80, amount 81 disposed at the front of the bottom of the saddle, two rail supports 82 disposed at the rear of the bottom of the saddle, and a seat rail90 formed by bending a metal rod, which is installed between the mount 81 and the two rail supports 82. The seat rail 90 has a U-shape turning part 91 and two (left and right) support arms 92 extending backwardly from the turning part 91, and the turning part 91 is plugged into and combined with the mount 81 of the cushion body 80, and the rear ends of the two support arms 92 are plugged into and combined with the two rail supports 82 of the cushion body 80 respectively.


However, the conventional bicycle saddle has the following drawbacks. Although a rider can have basic elasticity while riding by means of stuffing a material such as foam or silicone into the cushion body 80, there is no other structural design provided for buffer and shock absorbance. What is more, both sides of the cushion body 80 are combined with the two support arms 92 of the seat rail 90 directly, and the overall elasticity and buffering effect of the saddle are limited, thus causing discomfort. More importantly, the seat rail 90 is assembled with the cushion body 80 by force insertion, thus making the installation and disassembly difficult and the bonding strength between the seat rail 90 and the cushion body 80 is low, and failing to provide a comfortable and secured saddle.


SUMMARY OF THE DISCLOSURE

The present disclosure provides aseat rail locking structure of a saddle, which includes: a cushion body having a fixing part disposed at the front end of the bottom of the cushion body, and two elastic elements disposed on two sides of the rear end of the bottom of the cushion body respectively, and each elastic element having a through hole formed at the center of the elastic element; a connecting base, having a combining part disposed at each of the two ends of the combining part, and the two combining parts being attached to the bottom ends of the two elastic elements respectively, and each of the two combining parts having a combining hole formed at the center thereof and a locking unit being passed through the combining holes of the two combining parts and the through holes of the two elastic elements and locked to the two sides of the rear end of the bottom of the cushion body separately, and the connecting base having an insert slot formed at a middle section of the front of the connecting base, and the connecting base further having a positioning hole formed at a middle position of the top of the connecting base and communicating with the insert slot; a seat rail, having a turning part disposed at the front end of the seat rail, and a support arm extending backwardly from two ends of the turning part separately, and each of the two support arms having a clamped section connected to an inwardly extended bend section, and the turning part being combined and fixed to the fixing part of the cushion body, and the clamped section and the bend section disposed at the rear ends of the two support arms being plugged into the insert slot of the connecting base; a stopper, socketed into the insert slot of the connecting base, for stopping and fixing the bend sections of the two support arms of the seat rail, and clamping and limiting the clamped sections of the two support arms of the seat rail, and the stopper having a snapping hole formed at a middle position of the stopper; and a fastener, inserted into the positioning hole of the connecting base and the snapping hole of the stopper, for combining and fixing the stopper with the connecting base.


It is a primary objective of this disclosure to provide a simple installation/disassembly of the seat rail with the cushion body and enhance the bonding strength between the seat rail and the cushion body.


Another objective of this disclosure is to provide two elastic elements between the connecting base and the cushion body, and a stopper in the insert slot of the connecting base in order to enhance the buffer and shock absorbent effect and improve the riding comfort of the bicycle saddle.

The cushion body 10 includes a fixing part 11 disposed at the front of the bottom of the cushion body 10, and two elastic elements 12 disposed on two sides of the rear of the bottom of the cushion body 10 respectively, and the two elastic elements 12 are in a hollow cylindrical form and made of a polyurethane material with a shock-absorbing effect, and the center of each elastic element 12 is formed with a through hole 121.


Each of the two sides of the connecting base 20 is provided with a combining part 21, and the two combining parts 21 are attached to the bottom ends of the two elastic elements 12 respectively, and the centers of the two combining parts 21 are formed with a combining hole 211, and a locking unit 212 is passed through the combining holes 211 of the two combining parts 21 and thethrough holes 121 of the two elastic elements 12 and locked to two sides of the rear of the bottom of the cushion body 10, so that the two elastic elements 12 are clamped between two sides of the rear of the bottom the cushion body 10 and the two combining parts 21of the connecting base 20, and the middle section of the front of the connecting base 20 is provided with a horizontal long insert slot 22, and the middle positon of the top of the connecting base 20 is formed with a positioning hole 23 which is communicated with the insert slot 22, and the positioning hole 23 is substantially hollow T-shaped, and the middle position of the bottom inside the insert slot 22 is provided with a sliding rib 221, and the middle position inside the insert slot 22 and far away from the opening of the insert slot 22 is provided with a positioning bump 222.


A turning part 31 is disposed at the front end of the seat rail 30, and a support arm 32 is extended backwardly from each of the two ends of the turning part 31, and each of the two support arms 32 has a clamped section 321 connected to an inwardly extended bend section 322, and the turning part 31 is combined and fixed to the fixing part 11 of the cushion body 10, and the clamped section 321 and the bend section 322 at the rear ends of the two support arms 32 are plugged into the insert slot 22 of the connecting base 20.


The stopper 40 is socketed into the insert slot 22 of the connecting base 20 and provided for stopping and fixing the bend sections 322 of the two support arms 32 of the seat rail 30 and clamping and limiting the clamped sections 321 of the two support arms 32 of the seat rail 30, and a snapping hole 41 is formed at a middle position of the stopper 40, and an elastic groove 42 is formed on two (left and right) sides of the snapping hole 41 separately, and a sliding groove 43 is formed at a middle position of the bottom of the stopper 40. The sliding groove 43 is slidably mounted onto sliding rib 221 of the connecting base 20, and two limit protrusions 44 are disposed at a middle position of the rear side of the stopper 40, plugged between the bend sections 322 of the two support arms 32 of the seat rail 30, and sheathed on two sides of the positioning bump 222 of the connecting base 20 respectively.


The fastener 50 is plugged into the positioning hole 23 of the connecting base 20 and the snapping hole 41 of the stopper 40, and the fastener 50 includes a positioning part 51 with a shape corresponding to the shape of the positioning hole 23 and a snapping part 52 with a shape corresponding to the shape of the snapping hole 41.
