(explanation of toilet seat lifting action)
Fig. 6 (a) and (b) are to be illustrated in the movable link that is applicable in the portable seat lifting device of the present invention, carries the toilet seat unit to be in the key diagram of upper/lower positions state and the key diagram that movable link is in uppermost position in fig-ure.In addition, the section of the A-A ' line of Fig. 6 (a) and (b) and Fig. 2 (a) is suitable.
This routine portable seat lifting device 1 is to be installed at the upper part that fixed head 2 is fixed on toilet seat body 11 (with reference to Fig. 1) and with toilet seat unit 10 above the movable platen 6 under 60 the state to use.
Shown in Fig. 6 (a), clean to wait beginning before, toilet seat 12 be positioned at toilet seat body 11 above, toilet seat unit 10 and movable platen 6 are in 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, has the function of the 1st brake 91.Like this, at this upper/lower positions, utilize the engaging power of the 1st brake 91, the braking torque of stepping motor 7 and the deadweight of toilet seat unit 10, toilet seat unit 10 can not rise arbitrarily.In addition, under this state, potentiometer 14 output makes toilet seat unit 10 be in the information of upper/lower positions.
From then under the state, when wanting to allow toilet seat unit 10 float in order to begin to clean, if the switch motion of stipulating, then stepping motor 7 rotates towards positive direction with the step number or the official hour of regulation.The result is the power that rotatablely moves of stepping motor 7, transmits to output pinion 80 by deceleration wheels 70, and shown in Fig. 6 (b), output pinion 80 rises right side slide block 51 by tooth bar 53.Can remove the engaging of the 1st brake 91 thus, left slider 52, movable platen 6 and toilet seat unit 10 rise with right side slide block 51 one.
The toilet seat unit 12 that ought to rise and drive, at the appointed time or regulation step number when driving, also following phenomenon can appear, promptly, when the no show uppermost position in fig-ure, in the way of rising, stop because of certain 1 former thereby toilet seat unit 10, though the generation of this bad phenomenon can not sent card sound by the 2nd brake 92 yet and is learnt, and also can detect by the output valve of potentiometer 14.Like this, when this bad phenomenon produces, according to carrying out reporting of this information by the testing result of potentiometer 14.In addition, feed back to the driving loop (not shown) of stepping motor 7 by the output with potentiometer 14, the disposal that can reset to the action of stepping motor 7 etc. is so that action thereafter no longer begins.
On the other hand, when cleaning finished to want to allow toilet seat unit 10 descend, under the state shown in Fig. 6 (b), if the switch motion that puts rules into practice, then stepping motor 7 carried out counter-rotating with the step number or the official hour of regulation.The result is that the power that rotatablely moves of stepping motor 7 is transmitted to output pinion 80 by deceleration wheels 70, and shown in Fig. 6 (a), output pinion 80 descends right side slide block 51 by tooth bar 53.Can remove the engaging of the 2nd brake 92 thus, left slider 52, movable platen 6 and toilet seat unit 10 descend with right side slide block 51.
And, toilet seat unit 10 descends the back till the engaging of carrying out the 1st brake 91, stepping motor 7 is stopped, during this period, the small-diameter gear 82 of output wheel 8 makes sensor gear 15 counter-rotatings, because of the output of potentiometer 14 changes, so the situation that can be from this output toilet seat unit 10 be dropped to assigned position detects.In addition, drop to assigned position, can report by the card sound that the 1st brake 91 sends for toilet seat unit 10.
The toilet seat unit 12 that ought to descend and drive, at the appointed time or regulation step number when driving, also following phenomenon can appear, promptly, when upper/lower positions of no show, in the way that descends, stop because of certain 1 former thereby toilet seat unit 10, though the generation of this bad phenomenon can not sent card sound by the 1st brake 91 yet and is learnt, can detect by the output valve of potentiometer 14 yet.Like this, when this bad phenomenon produces, according to carrying out reporting of this information by the testing result of potentiometer 14.In addition, feed back to the drive circuit (not shown) of stepping motor 7 by the output with potentiometer 14, the disposal that can reset to the action of stepping motor 7 etc. is so that action thereafter no longer begins.
(utilizing the down maneuver of manual toilet seat unit)
In this routine portable seat lifting device 1, after clean finishing, the toilet seat unit 10 that is in uppermost position in fig-ure can be with manually dropping to upper/lower positions.In this occasion, or not toilet seat unit 10 is not pressed by people's power to stepping motor 7 power supplies.
At this moment, though the decline of right side slide block 51 is by tooth bar 53, be passed to stepping motor 7 by output pinion 80 and deceleration wheels 70 again, in this example, because of the motor as drive source is a stepping motor 7, so can cause imbalance in stepping motor 7.And, in this example, motor as drive source is a stepping motor 7, connect by deceleration wheels 70 between 80 from stepping motor 7 to output pinion, so when manually making toilet seat unit 10 declines, the load of the braking torque of stepping motor 7 and deceleration wheels 70 has the effect as appropriate drag, so toilet seat unit 10 slowly descends.
In the occasion of the down maneuver of the toilet seat unit 10 that this utilization is manually carried out, toilet seat unit 10 drops to assigned position and also can report by the card sound that is sent by the 1st brake 91.In addition, owing to also can detect, therefore, can report the information that toilet seat unit 10 normally descends according to the output result of potentiometer 14 by the output of potentiometer 14.
(effect that this is routine)
As mentioned above, in this routine portable seat lifting device 1, owing to drive source as driving mechanism 5, used the stepping motor 7 that causes imbalance easily, so different,, then prevent easily and move in case applied excessive power during electronic action with the occasion of using the DC motor.Again owing to adopt stepping motor 7 as drive source, and connecting by deceleration wheels 70 between 80 from stepping motor 7 to output pinion, therefore when manually making 10 declines of toilet seat unit, the load of the braking torque of stepping motor 7 and deceleration wheels 70 is worked as suitable drag.Like this, when the toilet seat unit 10 that floats manually descends in usefulness, because of toilet seat unit 10 slowly descends, thus can not damage toilet seat 12 and toilet seat body 11 even do not dispose buffer gear yet, and fool proof.In addition, even applied excessive power mistakenly, also the rotor imbalance ground because of stepping motor dallies, so can not damage driving mechanism, and, even error ground sandwiches hand etc. between fixed component and the movable link, also can under the state that is not subjected to heavy load, stop, so fool proof.Like this, both can improve the ease of use of portable seat lifting device 1, can not need buffer gear again, correspondingly realize the miniaturization and the cost degradation of portable seat lifting device 1.
In this example, because the potentiometer 14 that has used the action to sensor gear 15 to detect, can monitor the position of toilet seat unit 10, therefore when this lifting action does not normally carry out, can make this information and report and then take suitable disposal.Like this, the lifting that can avoid toilet seat unit 10 is washing and cleaning operation under the halted state etc. on the way, so can trouble-savingly take place.
In addition, use the sensor gear 15 of rotating with movable platen 6 interlocks, potentiometer detects the rotation of sensor gear 15.Therefore, can be reliably to the position of movable platen 6, promptly, the position of toilet seat unit 10 detects.And, if adopt potentiometer 14, then only need the rotation of its rotation section and sensor gear 15 one to get final product, therefore, the position of toilet seat unit 10 can be carried out with low-cost configuration.In addition, if adopt sensor gear 15, then the lifting distance with movable platen 6 (toilet seat unit 10) irrespectively only rotates on the regulation position, so configurable in little space.
In addition, sensor gear 15, at movable platen 6 (toilet seat unit 10) from upper/lower positions to the rotation of carrying out between the rising stage of uppermost position in fig-ure less than 1 rotation, so need only the angle position of detecting sensor gear 15, can detect the position in the full moving range of movable platen 6.
In this routine portable seat lifting device 1, the drive source owing to as driving mechanism 5 has used the stepping motor 7 that causes imbalance easily, thus different with the occasion of using the DC motor, even do not apply big power, also can be with toilet seat unit 10 is descended.Again owing to adopt stepping motor 7 as drive source, and connecting by deceleration wheels 70 between 80 from stepping motor 7 to output pinion, therefore when manually making 10 declines of toilet seat unit, the load of the braking torque of stepping motor 7 and deceleration wheels 70 is worked as suitable drag.Like this, when the toilet seat unit 10 that floats manually descends in usefulness, because of toilet seat unit 10 slowly descends, thus can not damage toilet seat 12 and toilet seat body 11 even do not dispose buffer gear yet, and fool proof.In addition, even applied excessive power mistakenly, also the rotor imbalance ground because of stepping motor 7 dallies, so can not damage driving mechanism 5, and, even error ground sandwiches hand etc. between fixed component and the movable link, also can under the state that is not subjected to heavy load, stop, so fool proof.Like this, both can improve the ease of use of portable seat lifting device 1, can not need buffer gear again, correspondingly realize the miniaturization and the cost degradation of portable seat lifting device 1.
In this example, owing to used the potentiometer 14 of detecting sensor gear 15 actions, the position of toilet seat unit 10 is monitored, therefore when this lifting action does not normally carry out, can make this information and report and then take suitable disposal.
When carrying out lifting action, because left side bearing portion 510 contacts on its full week with respect to left side guide shaft 41, right side bearing portion 520 contacts on fore-and-aft direction with respect to right side guide shaft 42, and therefore, the position of movable agency 9 is prescribed at fore-and-aft direction and horizontal both sides.
At this moment, but since left side bearing portion 520 at the state that transversely becomes contact separation with respect to left side guide shaft 42.That is, left side bearing portion 520 becomes contact condition or leaves state according to the posture of movable agency 9 in the horizontal.Like this, left side guide shaft 42 and the contact condition of left side bearing portion 520 can be followed by the posture of the movable agency 9 of right side guide shaft 41 and right side bearing portion 510 defineds and be changed.Thus, at each part and then in assembling procedure, even about guide shaft 41,42 and about the precision of the depth of parallelism, size, position of bearing portion 510,520 low slightly, do not apply undue power between guide shaft 41 and the right side bearing portion 510 and between left side guide shaft 42 and the left side bearing portion 520 to the right yet.In addition, even movable agency 9 has been applied the moment of torsion of direction all around, do not apply undue power between guide shaft 41 and the right side bearing portion 510 and between left side guide shaft 42 and the left side bearing portion 520 to the right yet.Like this, during 10 liftings of toilet seat unit, between right side guide shaft 41 and the right side bearing portion 510 and between left side guide shaft 42 and the left side bearing portion 520 phenomenon can not take place to be tangled, so the action of toilet seat unit 10 is smooth.
In addition, owing to have a internal diameter in left side bearing portion 520 lower lower parts 522 in the left side through hole 521, therefore left side guide shaft 42 can be restrained into required Min. with the contact portion of left side bearing portion 520 greater than left side guide shaft 42.The contact condition of left side guide shaft 42 and left side bearing portion 520 is followed easily by the posture of the movable agency 9 of right side guide shaft 41 and right side bearing portion 510 defineds and is changed, thereby makes the action of toilet seat unit 10 more smooth.
And,,,, restrain in a certain scope so can swing because the protuberance 525 of movable agency 9 one sides is collided with the vertical plane 22 of fixed component 2 even rearward swing the bottom in the left side of movable agency 9.Therefore, even for example cause the change of movable agency 9 centers of gravity because of the open and-shut mode of toilet seat 12 and toilet cover 13, big inclination can not take place in movable agency 9 yet.
Again owing to constitute driving mechanism 5 with electric up-down movable agency 9, thus the burden when cleaning water closet can be alleviated, and, can eliminate the obstacle sense when contacting with the preceding toilet seat unit 10 of cleaning.
Driving mechanism 5 passes to the driving force of the above-below direction of the right side slide block 51 that is formed with right side bearing portion 510 in the movable agency 9, greater than left side bearing portion 520.At this moment, right side bearing portion 510 has had the function as the benchmark of regulation movable agency 9 positions, therefore, transmits the output pinion 80 of the driving force of stepping motor 7 and can not throw off with the engagement of the tooth bar 53 of right side slide block 51.In addition, during with electric up-down movable agency 9, the contact condition of left side guide shaft 42 and left side bearing portion 520 is to follow by the posture of the movable agency 9 of right side guide shaft 41 and right side bearing portion 510 regulations to change, therefore can not apply undue power between right side guide shaft 41 and the right side bearing portion 510 and between left side guide shaft 42 and the left side bearing portion 520, so only need to use the stepping motor 7 that required minimal torque can take place to get final product.
In addition, in this routine portable seat lifting device 1, the drive source owing to as driving mechanism 5 has used the stepping motor 7 that causes imbalance easily, so different with the occasion of using the DC motor, even applied big power, the also available unit 10 that manually makes slowly descends.Again owing to adopt stepping motor 7 as drive source, and connecting by deceleration wheels 70 between 80 from stepping motor 7 to output pinion, therefore when manually making 10 declines of toilet seat unit, the load of the braking torque of stepping motor 7 and train of reduction gears 70 is worked as suitable drag.Like this, when the toilet seat unit 10 that floats manually descends in usefulness, because of toilet seat unit 10 slowly descends, thus can not damage toilet seat 12 and toilet seat body 11 even do not dispose buffer gear yet, and fool proof.In addition, even applied excessive power during electronic action, also the rotor imbalance ground because of stepping motor 7 dallies, so can not damage driving mechanism, and, even error ground sandwiches hand etc. between fixed head 2 and the movable platen 6, also can under the state that is not subjected to heavy load, stop, so fool proof.Like this, both can improve the ease of use of portable seat lifting device 1, can not need buffer gear again, correspondingly realize the miniaturization and the cost degradation of portable seat lifting device 1.
In this example, because the potentiometer 14 that has used the action to sensor gear 15 to detect, can monitor the position of toilet seat unit 10, therefore when this lifting action does not normally carry out, can make this information and report and then take suitable disposal.
(other embodiment)
The foregoing description is that the action by 14 pairs of sensor gear 15 of potentiometer detects the structure that monitors 10 positions, toilet seat unit, but also can detect the position that monitors toilet seat unit 10 by certain 1 rotary angle position to the reduction gearing 71,72,73 that constitutes deceleration wheels 70.In this occasion,,, can realize cost degradation and miniaturization so can reduce the part number because of 1 one in a plurality of gears of sensor gear and formation deceleration wheels 70 constitutes.In addition, also can obtain the right side slide block 51 that lifting drives above-below direction the position or from output pinion 80 rotations, obtain the positional information of toilet seat 12.And, in the foregoing description, monitor for the position of toilet seat unit 10 to be to use potentiometer 14, but also can monitor the position of toilet seat unit 10 by the sensor of Hall IC etc.
In addition, in the foregoing description, right side bearing portion 510 is the complete all contacting structure with right side guide shaft 41, but also with respect to 41 contacting structure on fore-and-aft direction and left and right directions of right side guide shaft.In addition, for right side bearing portion 510, also can be only in 2 positions and right side guide shaft 41 contacting structure of the axis direction of right side guide shaft 41.
In sum, among the present invention, owing to constituted the driving mechanism that the movable link that the toilet seat unit is installed is risen and drives with electronic, the burden in the time of therefore can alleviating the water closet cleaning, and, can eliminate with clean before the toilet seat unit contact and the obstacle sense that causes.Owing to can detect, therefore can detect and take place to stop in certain way of causing unusually again by the lifting position of position detecting device to movable link.Thereby can make the disposal of action removing of reporting or take thereafter etc. to this unusual information has taken place.Like this, can avoid the washing and cleaning operation under the halted state on the way, so can trouble-savingly take place.
In addition, among the present invention, owing to constitute the driving mechanism that the movable link that the toilet seat unit is installed is carried out lifting with electronic, thus can alleviate burden when cleaning water closet, and, can eliminate the obstacle sense when contacting with the preceding toilet seat unit of cleaning.That the DC motor of high pulling torque takes place is different owing to producing reverse current with when counter-rotating again, the stepping motor that has adopted rotor idle running when reversing and caused imbalance is as the drive source of driving mechanism, so do not need big power when manually making the toilet seat unit decline operation of floating.Again owing to used the drive source of stepping motor as driving mechanism, therefore when manually making the toilet seat unit decline operation of floating, the braking torque of stepping motor works as drag.Like this, when the toilet seat unit that floats descends, because of the toilet seat unit slowly descends, so also can not damage toilet seat and toilet seat body even do not dispose buffer gear.In addition, even applied excessive power mistakenly, also the rotor imbalance ground because of stepping motor dallies, so can not damage driving mechanism, and, even error ground sandwiches hand etc. between fixed component and the movable link, also can under the state that is not subjected to heavy load, stop, so fool proof.Like this, both can improve the ease of use of portable seat lifting device, can not need buffer gear again, correspondingly realize the miniaturization and the cost degradation of portable seat lifting device.
Among the present invention,, become contact condition or leave state according to the posture of movable agency because the 2nd bearing portion in the horizontal.Like this, the contact condition of the 2nd guide shaft and the 2nd bearing portion can be followed by the posture of the movable agency of the 1st guide shaft and the 1st bearing portion defined and be changed.Thus, even the precision of the depth of parallelism of guide shaft and dead eye, size, position is low slightly, can be to applying undue power between the 1st guide shaft and the 1st bearing portion and between the 2nd guide shaft and the 2nd bearing portion yet.In addition, even movable agency has been applied the moment of torsion of direction all around, can be to applying undue power between the 1st guide shaft and the 1st bearing portion and between the 2nd guide shaft and the 2nd bearing portion yet.Like this, during the lifting of toilet seat unit, between the 1st guide shaft and the 1st dead eye and between the 2nd guide shaft and the 2nd dead eye phenomenon can not take place to be tangled, so the action of toilet seat unit is smooth.
