The second gear train set comprises aninput gear 52, aduplex gear 54 and theoutput gear 56, each of which have an axis that extends parallel to the axis of themotor shaft 12. Theinput gear 52 is connected to theoutput shaft 44 b of the planetary gear by a dead joint (interference or press fit) to rotate with it. Theduplex gear 54 comprises afirst meshing part 54 a and a secondmeshing part 54 b; the first meshingpart 54 a meshes with theinput gear 52 and the second meshingpart 54 b meshes with theoutput gear 56. The tooth number of thefirst meshing part 54 a is more than the tooth number of the second meshingpart 54 b such that the output gear rotates more slowly than the output shaft. Theinput gear 52, theduplex gear 54 and theoutput gear 56 are all housed in thesecond case part 94. Thelid 96 is fixed to the open ends of thefirst case part 92 and thesecond case part 94. - Referring to
FIGS. 5 to 7 , two opening devices are assembled to abase 100 of a toilet seat assembly. Thebase 100 comprises two mountingparts 102 having, at a center thereof, a containinghole 104. The coupling part 110 (seeFIG. 7 ) of the seat and cover of the toilet is located between the two mountingparts 102 of thebase 100. The two opening devices are fitted to the base 100 from below by the mountingbases 922, that is, screws passes through theholes 924 in the mountingbases 922 and are screwed in to screw holes in thebase 100. Thesecond case part 94 extends from the bottom side of the base 100 upward into the containinghole 104 and, when thecoupling part 110 of the seat or cover is placed between the two mountingparts 102 and after thecoupling hole 112 of thecoupling part 110 is aligned with the through hole of theoutput gear 56, theoutput axle 70 is passed through the thoughhole 962 of thelid 96 from the containinghole 104 and inserted into thecoupling hole 112 of the seat or the cover after passing through the through hole 94 a of thesecond case part 94 via the through hole of theoutput gear 56. The outer surface of theoutput axle 70 is a cylinder shape with two diagonally opposite flat portions extending in the axial direction and the shapes of the mounting hole of theoutput gear 56 and thecoupling hole 112 of the seat or the cover is adapted to mate with the shape of the cross section of theoutput axle 70, so that when theoutput gear 56 rotates, theoutput axle 70 and the seat or cover will also rotate with it. Theoutput axle 70 is thus arranged to be slidably received in the hole in the output gear and in thecoupling hole 112 but is form locked or keyed to cause the output gear and the cover or sear to pivotably rotate or move with it. - A
torsion spring 120 is fixed to theoutput axle 70 by a socket joint. One end (not shown) of the spring is fixed to thebase 100 and theother end 122 is fixed to theoutput axle 70. When the cover or seat of the toilet is located at a setting angle such as 70 degrees, thetorsion spring 120 is in a relaxed o free state. When the cover or seat is located at a position more than or less than the setting angle, thetorsion spring 120 will be in a deformation state, having the tendency to resiliently push the cover or seat back to the setting angle. It is to be understood that theother end 122 of thetorsion spring 120 can also be fixed to the cover or seat of the toilet. - In use, the
motor shaft 12 drives theoutput axle 70 to rotate via the first and second gear train sets 30, 50, so as to drive the cover or seat between first and second positions. When the micro processor determines that the opening angle of the cover or seat has reached a predetermined desired angle, such as 110 degrees, by processing the signal produced by theposition sensor 16, the power to the motor is turned off, so themotor shaft 12 stops rotating and the cover or seat stops at the desired position. - In the opening device of the present invention, the
output axle 70 can be freely assembled to the case or disassembled from the case without disassembling the case. Before the cover or seat of the toilet is assembled to thebase 100 of the toilet, theoutput axle 70 can be conveniently dissembled from the opening device for the convenience of aligning the coupling part of the cover or the seat between the two mountingparts 102 of thebase 100. After the coupling part of the cover or seat is correctly aligned between the two mountingparts 102 of thebase 100, theoutput axle 70 is passed through the throughhole 962 of thelid 96 from the containinghole 104 and inserted into thecoupling hole 112 of the seat or cover after passing through the through hole 94 a of thesecond case part 94 via the mounting hole of theoutput gear 56. Thus, the opening device of the present invention is suitable for use whether the coupling part of the seat or cover needs to be assembled inside the opening device or needs to be assembled outside the opening device. As the secondgear train set 50 is a parallel axes gear set which extends in a direction transverse to the axis of themotor shaft 12, theoutput axle 70 is spaced from but parallel to of themotor shaft 12. - Although the invention is described with reference to one or more preferred embodiments, it should be appreciated by those skilled in the art that various modifications are possible. Therefore, the scope of the invention is to be determined by reference to the claims that follow.
- In the description and claims of the present application, each of the verbs “comprise”, “include”, “contain” and “have” and variations thereof, are used in an inclusive sense, to specify the presence of the stated item but not to exclude the presence of additional items.
