DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flip-up type simple armrest which assists a Western-style toilet seat on a toilet seat and stands up.

[0002]

SUMMARY OF THE INVENTION The present invention relates to a seat for mounting a toilet seat, in which a plate material is placed on the rear portion of the upper surface of a Western-style toilet with the plate material mounting hole being superposed on the toilet seat mounting hole formed in the rear portion of the upper surface. The tip of the screw shaft provided on the hinge is inserted from above into the holes so that the plate is brought into close contact with the Western-style toilet, and the armrest is rotated by hinges for attaching armrests provided on the left and right ends of the plate. With such a configuration, when used, the armrest is lowered to the floor to assist in sitting on and rising from the toilet seat, and when not in use, the armrest is raised from the floor so as to stand by, so that the Western style toilet For those who need assistance in using it, it can be used with easy operation just lowering the armrest in the standby state to the floor, especially for people who need wheelchairs such as elderly wheelchairs. Therefore, the armchair can be easily transferred from the wheelchair to the toilet seat without being disturbed by the armrest, and can be used only by lowering the armrest in the standby state to the floor, while a person who does not need assistance can be in the standby state. In this configuration, a simple flip-up armrest having a novel structure in which the armrest does not become annoying is obtained.

Reference numeral 28 denotes a pin whose tip 28a is engaged with the recess k for preventing rotation. The pin 28 is screwed into a screw hole h provided in the coupling member 25 so that the tip 28a is inward. It protrudes from the peripheral surface 25a.

Reference numeral 30 denotes a screw portion f of the pin 26 at the center of the inner wall.
Is a hemispherical push button having a screw hole m to be screwed, and an annular groove n for attaching a spring on the outer periphery of the screw hole m.

The operation of the hinge 21 will be briefly described below. As shown in FIG. 4, when the leg 20 is lowered to the floor, the inside of the top g of the pin 26 screwed to the push button 30 is the spring t. The urging force abuts on the annular wall i of the through hole c of the stopper component member 24 and, for example, the protrusion j is fitted into one of the grooves b.
Is in the state shown by the solid line in FIG.

Next, when the push button 30 is depressed, the pin 26 is moved in the direction of the arrow indicated by V against the urging force of the spring t, and the tip 28a of the pin 28 is turned into the detent k for preventing rotation.
Slides while engaged with. That is, the top g of the pin 26 and the annular wall i of the stopper component 24 are separated from each other, and the projection j is shifted from the groove b to the groove a.

Subsequently, the leg 20 is rotated. in this case,
The leg 20 rotates inward about the axis e of the pin 26. During this time, the protrusion j slides in the groove a and reaches the other groove b ′, and when it is fitted in the groove b, the leg 20 is in the state shown by the two-dot chain line in FIG.

In FIGS. 1 and 2, reference numeral 40 denotes a spacer made of, for example, resin inserted between the nut 41 for the screw shaft 8 and the Western toilet 2, and reference numeral 42 denotes a spacer 40.
And a washer inserted between the nut 41.

Then, the plate 16 is placed on the upper rear portion A of the Western-style toilet 2 with the plate mounting hole 17 superimposed on the toilet seat mounting hole 3 formed in the rear upper portion A of the toilet bowl 2. The distal end of the screw shaft 8 provided on the hinge 9 is inserted from above into the holes 17 and 3 so that the plate 16 is in close contact with the Western style toilet 2, and the armrest mounting hinges 23 provided on the left and right ends of the flat plate 16. , 23 so that the armrest can be rotated, the armrest 18 can be lowered to the floor 4 as shown by the solid line in FIG. When not in use, the armrest 18 can be made to stand by with the armrest 18 raised from the floor 4 as shown by the two-dot chain line in FIG. 1. For those who need assistance in using the Western toilet 2,
The armchair 18 in the standby state can be used by an easy operation of lowering the armchair 18 to the floor 4, and particularly for a person who needs a wheelchair such as an elderly person in a wheelchair, the armchair 18 can easily move from the wheelchair to the toilet seat 5 without disturbing the wheelchair. Can be used and the armrest 18 in the standby state can be used simply by lowering it on the floor 4, but the armrest 18 does not become annoying in the standby state even for a person who does not need assistance. Further, since the push button 30 has a rounded shape, even if the push button 30 is operated in the same manner, the push button 30 can be easily operated without being caught as compared with, for example, a lever shape.

FIG. 5 shows a second embodiment of the flip-up type simple armrest body 1. In this embodiment, unlike the above embodiment, the legs are integrated. That is, the leg is constituted by the pair of vertical members 20a, 20a and the horizontal member 20b, and the horizontal member 20b is brought into contact with the floor 4, thereby preventing the armrest body 1 from being uneven.

FIG. 6 shows a third embodiment of the flip-up simple armrest body 1, which is different from the embodiment shown in FIG. 2 in that the armrest body 19 has a slip preventing function, for example, a rubber cushion or the like. It is that such a thing was attached. Furthermore, if a rubber cushion or the like subjected to antibacterial treatment or the like is attached to the armrest body 19, slip can be prevented, and
Good hygiene.

FIG. 7 shows a toilet seat having, for example, a frame housing a switch for washing with hot water or the like, which is interposed between the lower surface of the hinge for mounting the toilet seat and the upper rear portion of the Western style toilet by screwing. A fourth embodiment of the present invention in which the plate of the armrest is formed in a shape corresponding to the shape of the switch box is shown.

In FIG. 7, reference numeral 50 denotes a frame housing a switch for washing with hot water and the like. The flip-up type simple armrest body 1 includes a plate member 56 having a shape corresponding to the shape of the frame body 50, hinges 23 for attaching armrests provided on left and right ends 56 a, 56 a of the plate member 56, The armrest 58 is composed of armrests 58 and hinges 21 and 21 for attaching legs.
9 and legs 60. In this embodiment, the interval between the hinges 23 is longer than the interval between the hinges 21 by an amount corresponding to the length of the frame 50.

[0024]

As described above, the armrest is rotatably attached to the rear of the upper surface of the Western style toilet via the plate material,
When used, the armrest is lowered to the floor to assist in sitting and rising on the toilet seat, and when not in use, the armrest is configured to be able to stand by with the armrest raised from the floor. Compared to armrests that need to be fixed on the floor, for those who need assistance in using a Western-style toilet, especially those who need a wheelchair such as the elderly in a wheelchair, the armrest rises from the floor. This is advantageous in that the wheelchair can be easily transferred from the wheelchair to the toilet seat without being disturbed by the armrest, and can be easily transferred from the toilet seat to the wheelchair, and is inexpensive.
