Patent ID: 8226058

Claim:
A saddle mounting device comprising: a support member having a mounting portion formed thereon and extending from one end thereof, the mounting portion configuring into an arc shape, the mounting portion having an elongated groove defined therein; a lower base fixedly connected with the support member and located above a top of the mounting portion, the lower base having a through hole defined therein, the lower base having two guiding flanges formed thereon and diametrically located around the through hole, each guiding flange having a guiding surface disposed on a top thereof, two gaps respectively defined between the two guiding flanges, the lower base having two first engaging grooves defined in a top thereof and respectively located at two opposite sides thereof; an upper base movably connected with the lower base and located above the top of the lower base, the upper base having a screw hole defined therein and extending therethrough, the upper base having two sliding rods formed thereon and extending from a bottom thereof, the two sliding rods respectively corresponding to the two guiding surfaces of the two guiding flanges, such that each sliding rod slides along the corresponding guiding surface of the guiding flange and is guided into the corresponding gap, the upper base having two second engaging grooves defined in the bottom thereof and respectively located at two opposite sides thereof for corresponding to the two first engaging grooves; a fastener passing through the elongated groove of the mounting portion and the through hole of the lower base and screwed in the screw hole, the upper base simultaneously rotatably moved relative to the lower base by a rotation of the fastener; and a coil spring compressibly sleeving on the fastener and disposed between the lower base and the upper base, one of the two guiding flanges having a channel defined therein, the coil spring having a distal end engagedly received in the channel, the other distal end of the coil spring abutting between two sliding rods, the coil spring providing a resilient force to restore the upper base when the upper base releasing from the lower base; wherein when the fastener is rotated to simultaneously drive the upper base to rotate, each sliding rod slides along the corresponding guiding surface and is guided into the corresponding gap, the two sliding rods respectively restricted within the two gaps, the fastener rotated to drive the upper base to axially move toward the lower base, the two first engaging grooves of the lower base and the two second engaging grooves of the upper base adapt to respectively securely receive two rails of a saddle.
