DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a heated toilet seat that is attached to a Western-style toilet bowl and provides warmth to the surface of the seat when the user is sitting on it.

2. Description of the Related Art Conventionally, this type of heated toilet seat is disclosed in, for example, Japanese Patent Application Laid-open No. 58-1574.
As shown in Publication No. 20, FIG. 4 and its A
The structure was as shown in Figure 5, which shows an enlarged view of the area.

That is, it is composed of a toilet seat 2 that has a heater 1 inside, and a main body 4 that has a control device 3 inside that controls the temperature of the heater 1, and the heater 1 and the control device 3 are electrically connected by a lead wire 5. There is. The lead wire 6 is a four-core electric wire with double insulation coating, and is wired to pass through the center of the rotation axis θ that rotatably supports the toilet seat 2 and the main body 4, and one is wired inside the toilet seat 2. is fixed to the fixing member 7, and the other is fixed to the main body 4.
It is connected to the control device 3 inside. The rotation shaft 6 is the toilet seat 2
A spring 10 that has a substantially cylindrical body with a buckle portion 8 at the side end, and whose end is supported by a rib 9 formed integrally with the toilet seat 2.
The buckle portion 8 is pressed and attached. O-rings 11 and 12 are attached to the holes through which the rotating shaft 6 passes through the toilet seat 2 and the main body 4, respectively, to prevent the intrusion of toilet, water, etc. 13 is a power cord that supplies power to the control device 3, and 13' is a temperature control switch connected to the control device 3.

Problems to be Solved by the Invention However, with such a configuration, when wiring the lead wire 6 through the rotating shaft 6, first connect the rotating shaft 6 to the toilet seat 2.
This can only be done after it has been installed. Toilet seat 2
When the lead wire 5 is wired through the shaft 6 with the rotation shaft 6 attached, the lead wire 6 may come into contact with the rib 9 or the spring 10, making it difficult to pass through and resulting in very poor workability.

Also, the hole through which the rotating shaft 6 passes through the toilet seat 2 and the main body 4 is
Although the IJ rings 11 and 12 are attached, there is a large gap between the rotating shaft 6 and the through hole of the toilet seat 2, and the gap between the rotating shaft 6 and the through hole of the main body 4. An impactful shearing force was applied to the rotating shaft 6 at two through holes in the toilet seat 2 and the main body 4, and the rotating shaft 6 was sometimes damaged at an early stage.

Further, although the spring 10 is used to fix the rotating shaft 6, the structure is complicated and the ease of assembly is poor.

In addition, the lip 9 may be damaged due to impact or the spring 10 may deteriorate and break due to ammonia gas, etc. In this case, the force to press the rotation shaft 6 is lost, and the rotation shaft 6
may come off and damage the lead wire 6. Rotation axis 6
Even if the removal does not reach the point where it falls, if the load on the spring 10 is reduced, when the toilet seat 2 is rotated, there is a possibility that the rotating shaft 6 will not rotate and the O-ring 110 will rotate. be.

In that case, since the lead wire 6 is fixed to the toilet seat 2 by the fixing member 7, the lead wire 5 rotates at the same time as the toilet seat 2, and there is a possibility that the lead wire 5 contacts with the inner surface of the rotating shaft 6 and becomes disconnected.

Therefore, the present invention is intended to solve this problem.

Means for Solving the Problems and Means of the present invention for solving the above-mentioned problems is to pass the lead wire connecting the heater of the toilet seat and the control device provided in the main body through the rotating shaft, and to It is press-fitted into the toilet seat from the outside in a restrictive manner.

For production The effect of this technical means is as follows.

That is, after passing the lead wire through the rotating shaft, the rotating shaft can be press-fitted and fixed from the outside of the toilet seat, so the workability of wiring the lead wire is very good.

Since the rotating shaft is press-fitted into the toilet seat, there is no gap between the rotating shaft and the rotating shaft insertion hole of the toilet seat, so when the user sits on the toilet seat,
Shocking shearing force is not applied to the rotating shaft. That is, it is possible to provide a rotating shaft with high durability.

In addition, the rotating shaft is simply press-fitted into the toilet seat compared to a fixed one, so the structure is simple and easy to assemble.

In addition, since the rotation axis is securely fixed to the toilet seat,
The rotating shaft does not come off, and when the toilet seat is rotated, the toilet seat, rotating shaft, and lead wire all rotate at the same angle at the same time, so the lead wire will not be damaged or worn out.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 is an exploded perspective view of a heated toilet seat according to an embodiment, and 14 is a toilet seat in which a heater 15 is disposed and which generates heat from the surface when a user sits on it. 16 is a main body, and a base 17 and a case 18 constitute an outer shell. On the top surface of the base 17, there is a control device 19 that controls energization of the heater 15 and keeps the surface temperature of the toilet seat 14 constant according to input from a temperature sensor (not shown) installed inside the toilet seat 14. It has been added. A rotating shaft 20 and a rotating shaft 21 are provided at both rear ends of the toilet seat 14, and the rotating shaft 21 is formed integrally with the toilet seat 14. The rotation shaft 2o stands up integrally from the base 17, and is fitted into a U-groove portion of a fixed wall 22 having a U-groove on its upper surface, and is rotatably fixed by screwing a mounting bracket 23 from above. Similarly, the rotating shaft 21 is rotatably inserted into a horizontal hole in a fixed wall 24 that stands up integrally from the base 17 and has a horizontal hole on the side surface. Reference numeral 25 denotes a toilet lid that covers the surface of the toilet seat 14 when not in use, and has a pair of hinge parts 26 and 26' having cut-out bearing holes, and is fitted onto the rotation shaft 20 and the rotation shaft 21. has been done. That is, the toilet seat 14 and the toilet lid 26 are independently rotatably supported by the main body 16 by the rotation shaft 20 and the rotation shaft 21.
Only the toilet seat 14 and the toilet seat 26 can be rotated and propped up before sitting on the toilet, and the toilet seat 14 and the toilet seat 26 can be propped up at the same time when the toilet is for men. Reference numeral 27 denotes four lead wires led from the terminal of the heater 16 and the terminal of the temperature sensor inside the toilet seat 14, and electrically connected to the control device 19 by a connector, passing through the center of the rotating shaft 20. They are wired.

28 is a cam body integrally formed at the end of the rotating shaft 20;
When the toilet seat 14 is propped up, the base 1 on the lower surface of the cam body 20
It has the purpose of assisting the toilet seat 14 to stand on its own by being in pressure contact with the spring plate 29 attached to the toilet seat 7 . Reference numeral 30 is an adjustment volume for adjusting the surface temperature of the toilet seat 14, and is mechanically connected to a knob 32 inserted through a side hole 31 in the side of the case 18 and operated by the user. 33 is control device 1
This is a power cord for supplying power to the base 17, and the cord outlet portion 34 is fitted into the base 17. 34 is a protective cover, and the above-mentioned control device 19. Mounting bracket 23. Lead wire 27, cam body 20. Spring plate 29. Adjustment volume 3

FIG. 2 is a cross-sectional view of FIG. 1 in an assembled state, cut in the axial direction of the rotation axis 2°. The rotation shaft 20 is press-fitted into the toilet seat 14, and as shown in the perspective view of FIG. It is an integrally molded product consisting of a portion 36, a rotationally fixed portion 37 to the base 17, and a cam body 28, and is made of a material with high wear resistance such as polyacetal resin. Pressure insertion part 3
A claw-like protrusion 39 is provided on the lower surface of the toilet seat 6. When the rotating shaft 20 is press-fitted into the toilet seat 14, a claw-like protrusion 39 is engaged with the wall 38 of the toilet seat 14 to prevent the rotating shaft 2o from being removed. The pressure insertion part 36 is inserted into the toilet seat 1
However, the external dimensions of the press-insertion part 36 are equal to or slightly smaller than the dimensions of the press-fit hole of the ear part 40, and after press-fitting, there is almost no play in the rotation shaft 2o. do not have. Further, since the shape of the press-fitting portion 35 is non-circular, when the toilet seat 14 is rotated, the rotation shaft 20 reliably rotates at the same angle as the toilet seat 14, and the rotation shaft 2o rotates at the same angle as the toilet seat 14. It is designed so that it does not rotate relative to the other direction.

41 is a circular rib provided in the circumferential direction, and the rotation axis 20
This is a water drainer that prevents water etc. from entering the main body 16 through the water. The lip 41 is in contact with the mounting member 23 and the rotation shaft 2
It also has the purpose of preventing movement of the o in the axial direction. A lead hole 42 passes through the center of the rotating shaft 20, and a seed wire 27 is wired through the lead hole 42. 4
3 is a tube for bundling the lead wires 27 inside the lead hole 42.

As described above, according to the configuration of this embodiment, the work of penetrating the lead wire 27 to the rotating shaft 2o is to first connect the lead wire 27 led from one terminal of the heater 15 and the temperature sensor to the ear portion 40 of the toilet seat 14. After exposing the rotating shaft 20 to the outside through the press-fit hole, bundle the lead wires 27 and pass them through the lead hole 42 of the rotating shaft 20, and then insert the rotating shaft 2o into the press-fit hole of the ear 4o of the toilet seat 14. It only needs to be press-fitted, and since there are no obstructions when passing the lead wire 27 through, the penetration work can be carried out smoothly.

In addition, since the press-fitting part 36 of the rotating shaft 20 and the press-fitting hole of the ear part 4o are fixed with almost no play, even if the user sits on the toilet seat 14, an impactful shearing force is applied to the rotating shaft 20. The rotating shaft 20 is highly durable.

Since the rotary shaft 2o can be fixed simply by press-fitting, it is very easy to assemble.

The rotating shaft 2Q is still fixed to the toilet seat 14 so that it cannot rotate, so when the toilet seat 14 is rotated, the toilet seat 14, the rotating shaft 2o, and the lead wire 27 are surely rotated at the same angle. The lead wires will not be damaged or worn out.

Further, according to this embodiment, since the rotation shaft 20 is made of a material with high wear resistance, the rotation of the toilet seat 14 is smooth and the durability can be further improved.

Effects of the Invention In the present invention, the lead wire connecting the heater of the toilet seat and the control device is passed through the rotating shaft, and the rotating shaft is press-fitted into the toilet seat from the outside in a restrictive manner. It has a great effect.

That is, after the lead wire is wired through the rotating shaft, the rotating shaft can be fixed to the toilet seat, so the workability is very good.

In addition, simply by press-fitting the rotating shaft into the toilet seat, it is securely fixed without wobbling, so the configuration is simple and easy to assemble, and even if you sit on the toilet seat, no impactful shearing force is applied to the rotating shaft. There is no. Therefore, the durability of the rotating shaft is extremely high.

In addition, since the rotating shaft does not rotate relative to the toilet seat, when the toilet seat is rotated, the toilet seat, rotating shaft, and lead wire all rotate at the same angle, and the lead at the through-wiring part rotates at the same angle. This can prevent wire wear and damage.
