[explanation of the lifting action of toilet seat]
Fig. 5 (a) and (b) be in the portable seat lifting device that the present invention is suitable for, 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.
The portable seat lifting device 1 of this form is fixed on the upper part of closet body 11 (with reference to Fig. 1) with fixed head 2, on the other hand, uses under toilet seat assembly 10 being installed in above the movable platen 6 60 state.
Beginning before cleaning waits, shown in Fig. 5 (a), toilet seat 12 be positioned at closet body 11 above, 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.In addition, 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 rotates to positive direction with the number of steps or the official hour of regulation.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 before the 2nd block 92 places engaged, after toilet seat assembly 10 rose, stepping motor 7 stopped.During this period, 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.In addition, toilet seat assembly 10 rises to this situation of 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.
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 is rotated to opposite direction with the number of steps or the official hour of regulation.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 (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 before the 1st block 91 places engaged, after toilet seat assembly 10 descended, stepping motor 7 stopped.During this period, 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.In addition, toilet seat assembly 10 drops to this situation of the position of regulation, can take sound with the card that takes place at the 1st block 91 places and report.
[action specification of ratchet mechanism]
In this form, when the direction that whether is driving irrespectively, descending to toilet seat assembly 10 in the driving process to certain positive and negative 1 direction with stepping motor 7 has applied overladen occasion, utilize ratchet mechanism 79 can disconnect being connected of stepping motor 7 and toilet seat assembly 10.Promptly, in this form, in the occasion that toilet seat assembly 10 is lifted, because magnet rotary body 75 is rotated to the V direction shown in Fig. 4 (a), so the 75f of the wall portion side butt of the claw 74d of pinion rotary body 74 and the circumferencial direction of the 75e of tooth portion, pinion rotary body 74 is followed magnet rotary body 75 and is rotated.Here, when toilet seat assembly 10 being applied load, the butt increased pressure of the 75f of wall portion of claw 74d and the 75e of tooth portion.Though keep both engagings can reach the maximum butt pressure that can keep both to engage always, but occasion in this form, because it is big to utilize the transferable duty ratio of driving force of stepping motor 7 to utilize ratchet mechanism 79 to disconnect the overload of transmitting, so before the stepping motor imbalance, surpass the maximum butt pressure of the engaging that can keep both.Its result, to the pawl arm 74c deflection to the inside that the V direction extends, claw 75d crosses over the wall 75f of portion.Promptly, when the overload that applies to toilet seat assembly 10 more than the maximum butt pressure, the ratchet mechanism 79 that is located between pinion rotary body 74 and the magnet rotary body 75 works, the rotation of magnet rotary body 75 continues to carry out, pinion rotary body 74 can not be followed the rotation of magnet rotary body 75, and disconnection stepping motor 7 is connected with toilet seat assembly 10.
[effect of this form]
As mentioned above, in the portable seat lifting device 1 of this form, owing to constituted the driving mechanism 5 that makes movable platen 6 that toilet seat assembly 10 is installed rise and descend in electronic mode, 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.In addition, ratchet mechanism 79, when making movable platen 6 rise or descend, because the overload that the direction that descends for movable platen 6 applies, make the disconnection that is connected of stepping motor 7 and movable platen 6, so in the time of on being sitting in toilet seat 12, carried out making the occasion of the switching manipulation that toilet seat assembly 10 rises mistakenly, or in the process that toilet seat assembly 10 rises or descends, applied the occasion that is sitting in excessive power such on the toilet seat 12 mistakenly, can prevent the damage of driving mechanism 5.
In addition, because it is big to utilize the transferable duty ratio of driving force of stepping motor 7 to utilize ratchet mechanism 79 to disconnect the overload of transmitting, so can use the stepping motor 7 that can transmit the load bigger than overload.Therefore, can reduce the gear of train of reduction gears 70, perhaps can improve the actuating speed of movable platen 6 by reducing gear.In addition, because ratchet mechanism 79 worked before magnet rotary body 75 imbalance, so can prevent the unfavorable condition of damages such as engagement disengagement between the gear of the train of reduction gears 70 of carrying out the inertia force of the magnet rotary body 75 of rotation at a high speed because of overload causes imbalance, being caused or hypodontia.
[other example]
In addition, the toilet seat assembly 10 of above-mentioned example is to use the structure of the automatic decline of stepping motor 7, but also can be with toilet seat assembly 10 is descended.That is, in above-mentioned example, be connected with train of reduction gears 70 between stepping motor 7 and the output pinion 80.Therefore, using the occasion that toilet seat assembly 10 is descended, load with the corresponding generation of the speed reducing ratio of train of reduction gears 70, because the braking moment with stepping motor 7 has appropriate resistance sense, toilet seat assembly 10 is descended lentamente, collide with big power and closet body 11 so can prevent toilet seat assembly 10.Therefore, even buffer gear is not set, can not damage toilet seat assembly 10 and closet body 11 yet.
In addition, the ratchet mechanism 79 of above-mentioned example, when making movable platen 6 rise or descend, the overload that applies for the direction that descends to movable platen 6, adopted the structure that disconnects that is connected that makes stepping motor 7 and movable platen 6, and when movable platen 6 being risen or descend,, also can adopt the structure that is connected disconnection that makes stepping motor 7 and movable platen 6 for the overload that the direction that rises to movable platen 6 applies.At this moment, as above-mentioned example, when the direction that toilet seat assembly 10 is descended applies overload, constituted the occasion of rotating to the W direction at pinion rotary body 74, pawl arm 74c just need give prominence to the W direction on the contrary with Fig. 4 (a) and be shaped.Make such structure, in the process that makes toilet seat assembly 10 rise or descend,, can prevent the damage of driving mechanism when applying the occasion of toilet seat 12 being lifted excessive like that power mistakenly.
In addition, ratchet mechanism 79, when making movable platen 6 rise or descend, apply the overladen both sides of ascent direction for the overload that applies descent direction to movable platen 6 with to movable platen 6, also can adopt the structure that disconnects that is connected that makes stepping motor 7 and movable platen 6.For example, the occasion that realizes at the ratchet mechanism 79 that utilizes above-mentioned example, the 75g of wall portion by making the 75e of tooth portion and the inclined-plane of the 75f of wall portion form the inclined-plane of the inclination opposite with circumferencial direction, for the overload that applies ascent direction to movable platen 6, claw 74d are kept out of the way to the inside.Its result applies the overladen both sides of ascent direction for the overload that applies descent direction to movable platen 6 with to movable platen 6, stepping motor 7 and being connected of movable platen 6 can both be disconnected.
