This will be described in detail. As shown in FIGS. 5 and 6, a long hole in the front-rear direction is formed in the intermediate portion of the stopper piece 31.
36 is formed. A flanged retaining member 37 is attached to the long hole 36 from below.
Of the retaining member 37 and the fixing member 30
Then, the stopper piece 31 is attached to the lower surface of the fixing member 30 so as to be slidable back and forth.

Further, an inclined piece portion 31a bent upward by a predetermined angle θ is formed at the rear end portion of the stopper piece 31.
The predetermined angle θ is set to about 20 ° to 40 °. Further, a hanging piece 31b having a through hole in the front-rear direction is formed at the front end portion of the stopper piece 31. The manual operation lever 33 slides forward and backward relative to the stopper piece 31.
And a vertical rod portion 33b having a grip member 34 attached to its tip.
And. Nut members 39, 39 are screwed to the rear end of the front-rear rod 33a.

At the front end of the fixing member 30, a manual operation lever 33

Through. Further, holding pieces 38, 38 having through-holes through which the front-rear direction rod portion 33a of the manual operation lever 33 is slidably inserted and swingable right and left are fixed to the back surface of the fixing member 30.

Further, the front-back direction rod portion 33a and the stopper piece 31
Between the first and the second elastically urging the stopper piece 31 backward.
A spring member 35 is provided. The first spring member 35 is composed of a compression spring, and its rear end portion abuts on the front surface of the hanging piece 31b of the stopper piece 31, and its front end portion abuts on a stopper member 41 attached to the intermediate portion of the front-back direction rod portion 33a.

Further, when the stopper piece 31 is separated from the lateral bar 32, the stopper piece 31 slides forward between the front and rear levers 33a and the stopper piece 31 by operating the manual operation lever 33. A second spring member 40 is provided which absorbs the difference between the stationary stopper piece 31 and the movement of the manually operated lever 33 in the locked state where the stopper piece 31 is in contact with the lateral bar 32 (see FIGS. 10 and 10). 9).

The second spring member 40 is composed of a compression spring like the first spring member 35. The front end portion of the second spring member 40 is pressed against the rear surface of the hanging piece 31b of the stopper piece 31, and the rear end portion is It is pressed against the nut member 39 at the rear end of the longitudinal rod 33a.

Further (returning to FIG. 5 and FIG. 6), the manual operation lever 33 is provided between the front-back direction rod portion 33a and the frontmost holding piece 38.
Is provided with a third spring member 42 for elastically biasing forward. The third spring member 42 is composed of a tension spring, and its front end has a holding piece 38.
And the rear end is locked to the locking piece 43 attached to the front-back direction rod portion 33a.

Then, in order to sit down on this apparatus, as shown in FIG.
As shown in FIG. 1, the toilet seat 1 is seated on the toilet seat 1 in a state where the toilet seat 1 is in the forward and downwardly raised position. At this time, 1.3 × H
Due to the relationship of ≦ H ′ ≦ 1.7 × H, the toilet seat 1 is located at a position slightly lower than the buttocks of the standing person, so that the buttocks contact the toilet seat 1 only by slightly lowering the waist.

If the user sits on the toilet seat 1 as it is, the gas spring 3 is gradually shortened by the weight and the toilet seat 1 is lowered. An orifice is provided inside the gas spring 3 for slowing the expansion / contraction speed of the gas spring 3. As a result, even when a person with a large weight is seated, the toilet seat 1 slowly descends and is safe.

As described above, the toilet seat 1 descends and the toilet seat 1
Just before the horizontal position of the lock mechanism, as shown in FIG.
The lower surface of the inclined piece portion 31 a of the stopper piece 31 of 28 comes into contact with the upper edge of the horizontal bar 32. At this time, the vertical rod portion 33b of the operating lever 33 is inclined to either the left or right side and is locked in the notch at the rear portion of the T-shaped slit portion 30a. After that, the stopper piece 31 slides forward while the lower surface of the inclined piece portion 31a slides on the upper edge of the horizontal bar 32, and the rear edge of the inclined piece portion 31a is brought to the front surface of the horizontal bar 32 as shown by an imaginary line. It descends while sliding.

After that, when the inclined piece portion 31a of the stopper piece 31 gets over the lateral bar 32, the stopper piece 31 slides backward by the elastic biasing force of the first spring member 35, and the inclined piece portion 31a.
Protrudes rearward from the horizontal bar 32.

Thus, as shown in FIG. 3, the toilet seat 1 is in the horizontal descending position. At this time, even if the physically handicapped person adjusts the sitting posture and floats his / her waist, the base end portion of the inclined piece portion 31a of the stopper piece 31 comes into contact with the lower end edge of the horizontal bar 32 from below as shown in FIG. Since it is in the locked state, it is possible to prevent the toilet seat 1 from rising further and it is safe. Further, due to the inclination of the inclined piece portion 31a, the frictional force when the inclined piece portion 31a is slid forward becomes extremely large.

Therefore, as shown in FIG. 9, the operating lever 33
Even if the sliding member is slid forward, the elastic biasing force of the second spring member 40 is smaller than the frictional force, and the stopper piece 31 does not slide forward, so that the locked state can be maintained.
It is even safer. When no one is seated in the horizontal state of the toilet seat 1, even if the operation lever 33 is slid forward, the locked state can be maintained in the same manner as described above, and the safety is extremely high.

In order to stand up after finishing the toilet in the seated state shown in FIG. 3, the vertical rod 33b is erected vertically and the operating lever 33 is slid forward as shown in FIG. 10 and FIG. Let At this time, since the inclined piece portion 31a of the stopper piece 31 is below the lower end edge of the horizontal bar 32, the stopper piece 31 is pushed forward by the elastic urging force of the second spring member 40, and the inclined piece portion 31a is pushed forward. 31a moves forward of the horizontal bar 32 and is in a released state.

In this released state, when a weak person lifts his / her waist, the toilet seat 1 is raised to the forward downward tilted rising position (shown in FIG. 2) with only a light force due to the push-up force of the gas spring 3. . The orifice of the gas spring 3 raises the toilet seat 1 slowly, which is safe.

Furthermore, the above 1.3 × H ≦ H ′ ≦ 1.7.
Due to the relationship of × H, the toilet seat 1 rises to a sufficiently high position, so that the buttocks can be pushed up to a position close to the standing state. Therefore, even a physically handicapped person can easily stand up by himself.

If 1.3.times.H> H ', the toilet seat 1 does not rise to a sufficiently high position, and relatively large force must be applied when sitting and standing up, which is not suitable for a physically handicapped person. Also, H '> 1.7 x H
Then, since the toilet seat 1 rises to an excessively high position, the buttocks cannot be applied to the toilet seat 1 when sitting, or the whole body of a weak person may float when standing up, which is dangerous. .

Further, the toilet seat 1 is connected by the unequal-sided quadrangular link 8.
Since the whole is pushed forward and upward, the buttocks of the weak can be pushed forward and upward, and it is easier to stand up.

Before standing up, pull the operating lever 33 of the lock mechanism 28 rearward to incline the vertical rod portion 33b and move it to the T position.
It is preferable to engage with the notch at the rear of the V-shaped slit portion 30a (see FIGS. 5 and 6). By doing so, when the next person sits down, the locking mechanism 28 is automatically locked, as described with reference to FIGS. 7 to 9.

Further, since the difference in elastic force of the gas spring 3 due to the difference in expansion and contraction stroke width is small, the pushing force is almost constant regardless of the height position of the toilet seat 1, and even a person with a light weight can surely sit down. At the same time, even a heavier person can push the buttocks up to a position close to the standing state.

Further, referring to FIGS. 1 to 4, a pivotal position adjusting tool.
The fastening piece 20 and the pivotal support member 22 can be removed from the fixing plate 17 by unscrewing the 14 fastening screws 23 and removing them from the pivotal support member 22. Then, the locking projection 18 of the tightening piece 20 is fitted into the other locking hole 16 of the fixing plate 17, and the tightening piece is tightened with the tightening screw 23.
If the 20 and the pivot member 22 are attached to the fixing plate 17, the position of the pivot 24 at the lower end of the gas spring 3 can be changed.

As a result, the force for pushing up the toilet seat 1 can be adjusted. That is, if the position of the pivotal portion 24 at the lower end of the gas spring 3 is slanted upward, the gradient of the gas spring 3 becomes smaller and the pushing force also becomes smaller. Further, if the position of the pivotal connection portion 24 at the lower end of the gas spring 3 is slanted downward, the gradient of the gas spring 3 increases and the pushing force also increases. Therefore, the most convenient push-up force can be obtained according to the weight of the user.

Further, in this toilet device, since there is no obstacle such as a pillar at the front end of the support frame 2, there is an advantage that even if it is installed in a small toilet, it does not interfere with the entry and exit of a weak person.

Although two gas springs 3 and 3 on the left and right are provided in the illustrated example, it is possible to omit either one of them.

Next, FIGS. 12 to 15 show a structure in which the connecting portion 44 between the front link rod 11 of the unequal-sided four-bar link 8 of the support frame 2 and the toilet seat mounting portion 12 above it is configured to be extendable. Show.

Further, in the horizontal lowered position of the toilet seat, the front link rod 11 and the vertical portion 12a of the toilet seat mounting portion 12 are arranged in a vertical posture. The other structures are the same as those in FIGS.

As shown in FIGS. 12 and 13, however, if the two short tubular members 45, 45 are fitted onto the inner pipe portion 11b, the vertical lengths of the front link rod 11 and the toilet seat mounting portion 12 are increased. Is the maximum, and the minimum height dimension H ″ of the front end portion 1a of the toilet seat 1 from the floor surface F in the lowered position is the largest value.

Further, as shown in FIG. 14, the inner pipe portion 11b
If one short cylinder 45 is fitted on the outside, the vertical lengths of the front link rod 11 and the toilet seat mounting portion 12 become intermediate values, and the minimum length from the floor surface F of the front end portion 1a of the toilet seat 1 in the lowered position. The height dimension H ″ is also an intermediate value.

Further, as shown in FIG. 14, the inner pipe portion 11
If the vertical portion 12a of the toilet seat mounting portion 12 is directly externally fitted to the b without the short tubular body 45 being externally fitted, the vertical lengths of the front link rod 11 and the toilet seat mounting portion 12 become the minimum value, and the vertical position at the lowered position The minimum height dimension H ″ of the front end portion 1a of the toilet seat 1 from the floor surface F is the smallest value.

As described above, the minimum height dimension H ″ of the front end portion 1a of the toilet seat 1 from the floor surface F can be adjusted in three steps. In addition, there is an advantage that the height adjustment is easy and the toilet seat 1 is not displaced back and forth even if the height is adjusted.

It should be noted that the number of the short tubular members 45 may be 3 to 5 as desired. If so, the minimum height dimension H ″ is 4 to
It can be adjusted in 6 steps.

Next, FIGS. 16 and 17 show a gas spring 3 which can be locked at an arbitrary expansion / contraction stroke position. Specifically, the cylinder portion 3 of the gas spring 3
