In addition, stepping motor 7 imbalances, on one side the magnet rotary body 75 of stepping motor 7 to the W direction rotate at a high speed, toilet seat assembly 10 descends on one side, the idle torque of the ratchet mechanism 79 when toilet seat assembly 10 arrives upper/lower positions (below be called " idle torque upward ") constitutes than the little state of idle torque downwards.This is idle torque upward, owing to be configured to not produce the state of damage for the driving mechanism 5 of train of reduction gears 70 and slide block 51 etc., so occasion that stops at toilet seat assembly 10, the driving mechanism 5 of train of reduction gears 70 and slide block 51 etc. is not applied undue load yet, can prevent the damage of driving mechanism.
[explanation of the lifting action of toilet seat]
Fig. 5 (a) and (b) be in using portable seat lifting device of the present invention, the expression movable link that carried the toilet seat assembly is positioned at the key diagram of upper/lower positions state and the key diagram that movable link is positioned at uppermost position in fig-ure.In addition, the section of the A-A ' line of Fig. 5 (a) and (b) and Fig. 2 (a) is suitable.Fig. 6 is the ideograph for the wiring relation of the stepping motor of having used portable seat lifting device use of the present invention, the bifilar winding of expression.Fig. 7 is the table that the excitation of utilizing the one pole energising to carry out when having used the stepping motor that uses in the portable seat lifting device of the present invention and make the toilet seat assembly carry out lifting is described in proper order usefulness, (A) being the excitation order that 2 phase excitations carry out of utilizing when the toilet seat assembly is risen, (B) is the excitation order of utilizing 1-2 phase excitation to carry out when the toilet seat assembly is descended.
The portable seat lifting device 1 of this form is fixed on the upper surface portion of closet body 11 (with reference to Fig. 1) with fixed head 2, on the other hand, uses under the state of the upper surface 60 that toilet seat assembly 10 is installed in movable platen 6.
Beginning before cleaning waits, shown in Fig. 5 (a), toilet seat 12 is positioned at the upper surface of closet body 11, and toilet seat assembly 10 and movable platen 6 are positioned at upper/lower positions.Under this state, the leading section of fastened component 95 engages with the downside recess 97 of the vertical plane 22 of fixed head 2, plays the function as the 1st block 91.Therefore, at this upper/lower positions, the engaging power on the 1st block 91 is utilized the braking moment of stepping motor 7 and the deadweight of toilet seat assembly 10, and toilet seat assembly 10 can carefully rise.Again, under this state, potentiometer 14 output toilet seat assemblies 10 are positioned at the information of upper/lower positions.
From this state, when wanting to make toilet seat assembly 10 to lift in order to begin cleaning, if the switch motion of stipulating, then stepping motor 7 utilizes 2 phase excitations to rotate to positive direction with number of steps or the official hour of stipulating.Its result, the power that rotatablely moves of stepping motor 7 is transmitted to output pinion 80 by train of reduction gears 70, and shown in Fig. 5 (b), output pinion 80 rises right side slide block 51 by tooth bar 53.Therefore, the engaging on the 1st block 91 is disengaged, and left slider 52, movable platen 6 and toilet seat assembly 10 just rise integratedly with right side slide block 51.
And 92 places engage to the 2nd block, and after toilet seat assembly 10 rose, stepping motor 7 stopped.During so far, the pinion 82 of output gear 8 makes sensor gear 15 rotation, because the output of potentiometer 14 changes, so can detect the situation that toilet seat assembly 10 rises to assigned position from this output.Again, toilet seat assembly 10 rises to the situation behind the assigned position, can take sound with the card that takes place at the 2nd block 92 places and report.And, stop at toilet seat assembly 10 under the state of uppermost position in fig-ure, utilize the engaging power on the 2nd block 92 and the braking moment of stepping motor 7, toilet seat assembly 10 can not fall because of deadweight.
In addition, for 2 phase excitations when toilet seat assembly 10 is risen, constitute 1 cycle (360 degree) with 48 step pitches, its excitation order becomes the state shown in Fig. 7 (A).Promptly, as shown in Figure 6, utilize control device 83, to become drive coil 77a, the d of the common terminal of 77b makes+, terminal e and c are made-, at drive coil 77a, the A of 77b flows through the 1st step pitch of electric current mutually mutually on (winding wire for the B phase flows through electric current to opposite direction) simultaneously with B (-), the d that will become common terminal makes+, terminal c and b are made-, at drive coil 77a, the B (-) of 77b flows through the 2nd step pitch of electric current mutually mutually on (winding wire for the A phase flows through electric current to opposite direction) simultaneously with A (-), the d that will become common terminal makes+, terminal b and a are made-, at drive coil 77a, the A (-) of 77b goes up the 3rd step pitch that flows through electric current simultaneously mutually with B mutually, the d that will become common terminal makes+, terminal a and e are made-, at drive coil 77a, the B of 77b goes up the 4th step pitch that flows through electric current simultaneously mutually with A mutually, becomes the state that carries out the input corresponding with the 1st～the 4th step pitch repeatedly.
On the other hand, want occasion that toilet seat assembly 10 is descended after cleaning finishes, when the switch motion of stipulating from the state shown in Fig. 5 (b), stepping motor 7 utilizes 1-2 phase excitation to be rotated to opposite direction with the step pitch number or the official hour of regulation.Its result, the rotary driving force of stepping motor 7 transmits to output pinion 80 by train of reduction gears 70, and shown in Fig. 5 (a), output pinion 80 descends right side slide block 51 by tooth bar 53.Therefore, the engaging on the 2nd block 92 is disengaged, and left slider 52, movable platen 6 and toilet seat assembly 10 just descend integratedly with right side slide block 51.
And till the engaging of carrying out the 1st block 91 places, after toilet seat assembly 10 descended, stepping motor 7 stopped.During so far, the pinion 82 of output gear 8 makes sensor gear 15 carry out reverse rotation, because the output of potentiometer 14 changes, so can detect the situation that toilet seat assembly 10 drops to the position of regulation from its output.Again, toilet seat assembly 10 drops to the situation behind the position of regulation, can take sound with the card that takes place at the 1st block 91 places and report.
In addition, for the 1-2 phase excitation when toilet seat assembly 10 is descended, constitute 1 cycle (360 degree) with 96 step pitches, its excitation order becomes the state shown in Fig. 7 (B).Promptly, as shown in Figure 6, utilize control device 83, to become drive coil 77a, the d of the common terminal of 77b makes+, terminal a is made-, the 1st step pitch in the B of drive coil 77b phase upper reaches overcurrent, the d that will become common terminal makes+, terminal a and b are made-, at drive coil 77a, the B of 77b goes up the 2nd step pitch that flows through electric current simultaneously mutually with A (-) mutually, the d that will become common terminal makes+, terminal b is made-, the 3rd step pitch in the A of drive coil 77a (-) phase upper reaches overcurrent, the d that will become common terminal makes+, terminal b and c are made-, at drive coil 77a, the A (-) of 77b goes up the 4th step pitch that flows through electric current simultaneously mutually with B (-) mutually, the d that will become common terminal makes+, terminal c is made-, the 5th step pitch in the B of drive coil 77b (-) phase upper reaches overcurrent, the d that will become common terminal makes+, terminal c and e are made-, at drive coil 77a, the B (-) of 77b goes up the 6th step pitch that flows through electric current simultaneously mutually with A mutually, the d that will become common terminal makes+, terminal e is made-, in the 7th step pitch of the A of drive coil 77a phase upper reaches overcurrent, the d that will become common terminal makes+, terminal e and a are made-, go up the 8th step pitch that flows through electric current simultaneously mutually with B (-) mutually at A, become the state that carries out the input corresponding repeatedly with the 1st～the 8th step pitch.
[action specification of ratchet mechanism]
In this form, the occasion making toilet seat assembly 10 come-ups makes magnet rotary body 75 be rotated to the V direction shown in Fig. 4 (a).Therefore, the 75f of the wall portion side butt of the circumferencial direction of the claw 74d of pinion rotary body 74 and the 75e of tooth portion and pinion rotary body 74 are followed magnet rotary body 75 ground and are rotated.Here, when toilet seat assembly 10 is applied the undue load of descent direction, as mentioned above, because the idle torque downwards of ratchet mechanism 79 is bigger than the opposite direction imbalance torque of stepping motor 7, thus the rotor imbalance, on one side to the W direction rotate at a high speed, one side toilet seat assembly 10 drops to closet body 11.
Soon, when toilet seat assembly 10 arrives upper/lower positions, stop at the upper surface of closet body 11.With this, ratchet rotary body 74 also stops.On the other hand owing on magnet rotary body 75, acting on the inertia force of the W direction that produces because of rotation at a high speed, so magnet rotary body 75 rotate to the W direction, its result, shown in Fig. 4 (a), the 75g of the wall portion side butt of claw 74d and the 75e of tooth portion.
Under the state of claw 74d and the 75g of wall portion butt, inertia further acts on the magnet rotary body 75, when the torque based on this inertia force become than ratchet mechanism 79 idle torque is big upward the time, magnet rotary body 75 begin idle running.
On the other hand, the occasion in that toilet seat assembly 10 is descended makes magnet rotary body 75 be rotated to the W direction shown in Fig. 4 (a).Therefore, the 75g of the wall portion side butt of the circumferencial direction of the claw 74d of pinion rotary body 74 and the 75e of tooth portion and pinion rotary body 74 are followed magnet rotary body 75 ground and are rotated.Here, when toilet seat assembly 10 is applied the undue load of descent direction, as mentioned above, because the idle torque downwards of ratchet mechanism 79 is bigger than the suitable direction imbalance torque of stepping motor 7, so rotor imbalance, rotate at a high speed to the W direction and drop to upper/lower positions on one side on one side, but when the torque based on the inertia force of magnet rotary body 75 become than ratchet mechanism 79 idle torque is big upward the time, magnet rotary body 75 similarly begins idle running with above-mentioned.
[effect of this form]
As mentioned above, in the portable seat lifting device 1 of this form, owing to constitute the driving mechanism 5 that makes movable platen 6 that toilet seat assembly 10 has been installed rise and descend with electronic, so when is cleaned in the depth below closet body 11 and toilet seat 12, do not need toilet seat assembly 10 up to be lifted or down pushed away with hand.Therefore, can alleviate burden when Western water closet cleaned.
Again, control device 83, littler owing to constituting than opposite direction driving torque along the direction driving torque, so be equivalent to, can make suitable direction imbalance torque approach to lack of proper care torque in the other direction in the other direction along the amount of direction driving torque with respect to the torque reduction of lacking of proper care.Therefore, can not cause that driving mechanism 5 damages in the overload that when the overladen direction that makes stepping motor 7 imbalances drives stepping motor 7, applies, and, be equivalent to along the amount of direction imbalance torque with respect to the torque reduction of lacking of proper care in the other direction, the desirable strength of driving mechanism 5 can be suppressed to less, so can wait the miniaturization that realizes driving mechanism 5 by the slimming that makes part.
In addition, occasion in this form, owing to make the needs of the rising or falling speed unanimity of toilet seat assembly 10, the frequency of the driving pulse by will making the stepping motor 7 that toilet seat assembly 10 descends makes 2 times of frequency of the driving pulse that makes the stepping motor 7 that toilet seat assembly 10 rises, and can make the actuating speed of stepping motor 7 consistent on both direction.Like this, occasion in the actuating speed that makes stepping motor 7 unanimity on both direction, actuating speed in any case, all because the driving torque that is produced by 2 phase excitations is bigger than the driving torque that is produced by 1-2 phase excitation all the time, thus with the frequency-independent ground of driving pulse, can make along direction driving torque ratio opposite direction driving torque little.
[other example]
In the occasion of above-mentioned example, when toilet seat assembly 10 is risen and when toilet seat assembly 10 is descended excitation mode is changed, but not necessarily only limit to the change of excitation mode.That is,, also can use various driving methods as long as it is littler than opposite direction driving torque that suitable direction driving torque is become.For example, magnitude of voltage or according to the apply electric current of limiter mode to coil 8 also can constitute the little state when toilet seat assembly 10 is risen of becoming when toilet seat assembly 10 is descended.But, littler than opposite direction driving torque in the occasion of this example in order to make along the direction driving torque, just need to increase some hardware component.
Again,, when toilet seat assembly 10 is risen, use 2 phase excitations, when toilet seat assembly 10 is descended, use 1-2 phase excitation, but not necessarily be limited to such excitation mode in the occasion of above-mentioned example.That is,, also can use various excitation modes as long as it is littler than opposite direction driving torque that suitable direction driving torque is become.For example, when toilet seat assembly 10 is risen, use 2 phase excitations, when toilet seat assembly 10 is descended, also can use 1 phase excitation.Again, also can when toilet seat assembly 10 is risen, use 1-2 phase excitation, when toilet seat assembly 10 is descended, use 1 phase excitation.
And, in above-mentioned example, the frequency that frequency identical, the driving pulse when toilet seat assembly 10 will be descended that excitation mode by will make 10 liftings of toilet seat assembly the time makes makes the driving pulse when toilet seat assembly 10 is risen is big, also can constitute to make along the direction driving torque than the little state of driving torque in the other direction.In addition, in the different occasion of the frequency that makes driving pulse, not necessarily need excitation mode is made identical, even suitably make up excitation mode and driving frequency also passable.
In addition, occasion at above-mentioned example, when being risen, uses by toilet seat assembly 10 2 phase excitations, when being descended, uses by toilet seat assembly 10 1-2 phase excitation, and, 2 times of the frequency of the driving pulse the when frequency of the driving pulse when toilet seat assembly 10 will be descended makes toilet seat assembly 10 is risen make the actuating speed of stepping motor 7 consistent on both direction, but not necessarily need to make actuating speed consistent on both direction, as long as, also actuating speed suitably can be changed becoming in the scope littler than opposite direction driving torque along the direction driving torque.
Promptly, utilize 2 phase excitations different with the excitation mode of 1-2 phase excitation, when toilet seat assembly 10 is risen and when toilet seat assembly 10 is descended, the frequency of the driving pulse of stepping motor 7 is identical occasion, because the actuating speed of the stepping motor 7 that is produced by 1-2 phase excitation becomes 1/2 times of actuating speed of the stepping motor 7 that is produced by 2 phase excitations, so make according to the frequency of driving pulse the driving torque that produces by 1-2 phase excitation with by the 2 driving torque counter-rotatings that produce of excitation mutually, take place along the direction driving torque than the big reversal development of opposite direction driving torque.Therefore, as long as in the scope that this reversal development does not take place, also can the actuating speed of stepping motor 7 suitably be changed.
