DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.

[0036] With reference to FIGS. 4-7, a saddle chair 1 according to a preferred embodiment of the present invention at least comprises: a first seat 11 and a second seat 12.

[0037] The first seat 11 includes a first connection sheet 111 connected with a bottom of the first seat 11 and an elongated orifice 112 defined on the first connection sheet 111.

[0038] The second seat 12 includes a second connection sheet 121 connected with a bottom of the second seat 12 and a through orifice 122 defined on the second connection sheet 121.

[0039] A fixing member 2 is mounted on the first connection sheet 111, and the fixing member 2 includes a slide slot 21 defined on a top thereof and having a slidable face 211 formed on a bottom of the slide slot 21, a receiving orifice 22 defined on a center of the slidable face 211, and a chute 212 extending downward from the slidable face 211.

[0040] A drive member 3 is inserted through the receiving orifice 22, the elongated orifice 112, and the through orifice 122 to connect with a retainer 4 which is connected with a bottom of the second connection sheet 121.

[0041] The retainer 4 includes a contacting face 41 formed on a top thereof and contacting with the bottom of the second connection sheet 121.

[0042] Two screw bolts 5 are inserted through the retainer 4 upward to screw with a bottom of the drive member 3.

[0043] A control bolt 6 is screwed with a threaded orifice 31 of the drive member 3 and includes at least one recess 61 defined on the control bolt 6.

[0044] At least one engagement block 7 is fitted on the at least one recess 61 of the control bolt 6 respectively, and each of the at least one engagement block 7 includes a screw 71 inserted into each of the at least one recess 61 and received in the slide slot 21. Each engagement block 7 further includes a forcing edge 72 formed on a bottom thereof and sliding between the slidable face 211 and the chute 212, when the control bolt 6 is rotated to move along the threaded orifice 31, as shown in FIGS. 4-7.

[0045] The chute 212 corresponds to a front side of the drive member 3 and has a tilted face 213 defined on a front end of the chute 212 and extending reward to the receiving orifice 22. The control bolt 6 has two recesses 61 corresponding to the front side and a rear side of the drive member 3 respectively, and when two engagement blocks 7 are fitted into the two recesses 61 of the control bolt 6 individually, two pressing faces 73 on two bottoms of the two engagement blocks 7 are tilted respectively, i.e., two front sides of the two pressing faces 73 are higher than two rear sides of the two pressing faces 73 individually, and two forcing edges 72 are formed on the two rear sides of the two pressing faces 73 respectively, as illustrated in FIG. 4.

[0046] The drive member 3 further includes two threaded orifices 32 defined in a bottom thereof, and the retainer 4 further includes two coupling orifices 42 defined thereon and corresponding to the two threaded orifices 32 respectively, wherein the two screw bolts 5 are inserted through the coupling orifices 42 of the retainer 4 upward to screw with the two threaded orifices 32 of the drive member 3 respectively, thus fixing the retainer 4 on the bottom of the drive member 3, as shown in FIG. 4.

[0047] In operation, the control bolt 6 is applied to control the two engagement blocks 7 to slide forward or rearward along the slide slot 21, and the two forcing edges 72 force on the slidable face 211 to press the fixing member 2 to contact with the first connection sheet 111 by mating with the contacting face 41 of the retainer 4 and the second connection sheet 121, thus fixing the first seat 11 and the second seat 12, as shown in FIGS. 5-7.

[0048] The control bolt 6 is rotated to control a front engagement block 7 of the two engagement blocks 7 to slide along the slide slot 21 so that the forcing edge 72 of the front engagement block 7 moves to the chute 212, and a rear engagement block 7 of the two engagement blocks 7 slides along the slide slot 21 so that the forcing edge 72 of the rear engagement block 7 removes from the chute 212 and the forcing edge 72 of the front engagement block 7 moves into the chute 212, hence a distance among the fixing member 2, the second connection sheet 121, and the retainer 4 is increased, thus releasing the first connection sheet 111. In the meantime, the first connection sheet 111 moves along the elongated orifice 112 to swing the first seat 11 to a desired position. Thereafter, the two forcing edges 72 of the two engagement blocks 7 are moved on the slidable face 211 so that the retainer 4 and the second connection sheet 121 are pulled upward to fix the first connection sheet 111, as illustrated in FIGS. 8 and 9. Referring to FIG. 8, the retainer 4 is pulled to retain the first connection sheet 111.

[0049] Thereby, the control bolt 6 controls the two engagement blocks 7 to move along the slide slot 21 so that the two forcing edges 72 are moved on the slidable face 211 to pull the retainer 4 upward, and the retainer 4 retains the first connection sheet 111. Alternatively, the control bolt 6 controls the two engagement blocks 7 to remove from the chute 212 along the slide slot 21 so as to increases the distance among the fixing member 2, the retainer 4, and the second connection sheet 121, thus releasing the first connection sheet 111 by moving the two engagement blocks 7 along the slide slot 21.

[0050] While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
