Abstract
Braking of independently-movable pivotable members is carried out by independent one-way clutch mechanisms which provide minimal braking force to the pivotable members in the vicinity of the limit points of their pivotable movement, and provide optimal braking force in a middle range of pivotable movement. The braking mechanism provided may operate on one or both of the pivotable members at the same time, each of the independent clutch mechanisms providing suitable braking force to compensate for the mass of the respective pivotable members.
Claims19
A speed governor for a device having at least first and second pivotable members which are pivotably movable independently of each other the speed governor comprising:
- first and second rotatable members which are rotatable independently of each other in response to respective pivotable movement of said first and second pivotable members;
- a gear train for increasing a speed of rotation of each of said first and second rotatable members and having a plurality of stages including a final stage;
- brake means, mounted on said final stage of said gear train, for braking said pivotable movements of said pivotable members;
- and
- first and second independent one-way clutches, each provided between a respective one of said first and second rotatable members and said brake means;
- and
- a common structure, provided from a driven side of each of said clutches to said brake means so that said brake means applies braking force to either of said first and second pivotable members when one of said first and second pivotable members is moved in a first direction, and to both of said first and second pivotable members when both of said pivotable members are moved in said first direction.
A speed governor for a toilet said toilet having a toilet seat and a toilet lid, said speed governor comprising:
- first and second independent shafts supported in a casing and projecting outwardly from said casing, said first and second shafts being connected respectively to said toilet seat and said toilet lid;
- means, contained within said casing, for increasing a speed of rotation of said first and second shafts;
- brake means, contained within said casing and connected to said speed increasing means, for decreasing a speed of rotation of said first and second shafts;
- and
- first and second independent one-way transmission clutches, each provided between a respective one of said first and second shafts and said brake means, so that each of said clutches is operable in response to the operation of a shaft corresponding thereto.
A speed governor for a toilet having first and second pivotable members each rotatable about an axis of rotation, the speed governor comprising:
- a first input shaft rotatable about said axis of rotation and connected to said first pivotable member;
- a second input shaft rotatable about said first input shaft and connected to said second pivotable member;
- a driven rotatable member rotatable about said axis of rotation;
- a first one-way transmission clutch provided between said first input shaft and said driven rotatable member, said first clutch transmitting a rotation of said first input shaft to said driven rotatable member when said first input shaft is rotated in a first direction, transmission of said rotation of said first input shaft to said driven rotatable member by said first clutch being prevented when said first input shaft is rotated in a second direction opposite said first direction;
- a second one-way transmission clutch provided between said second input shaft and said driven rotatable member, said second clutch transmitting a rotation of said second input shaft to said driven rotatable member when said second input shaft is rotated in a first direction, transmission of said rotation of said second input shaft to said driven rotatable member by said second clutch being prevented when said second input shaft is rotated in a second direction;
- and
- brake means, connected to said driven rotatable member, for braking said driven rotatable member when said driven rotatable member is rotated, so as to brake a rotation of the one of said first and second input shafts rotating said rotatable member.
A speed governor for a toilet having a reciprocally pivotable member, said speed governor comprising:
- an input shaft coupled substantially integrally to said reciprocally pivotable member;
- brake means, responsive to an angular movement of said input shaft, for braking said angular movement of said input shaft
- a one-way transmission clutch, provided between said brake means and said input shaft, for transmitting said angular movement of said input shaft to said brake means when said input shaft is angularly moved in a first direction, transmission of said angular movement of said input shaft to said brake means being prevented when said input shaft is angularly moved in a second direction opposite to said first direction;
- and
- brake release means, provided between said input shaft and said brake means, for releasing an operation of said brake means at a final stage of said angular movement of said input shaft in said first direction.
