[First Embodiment]
First, in the embodiment of the present invention, a toilet seat according to the first embodiment (hereinafter referred to as “this embodiment”) will be described.
<Composition of toilet seat>
FIG. 1 is a cross-sectional view schematically showing a toilet seat according to the present embodiment.
FIG. 1 shows a cross section taken along line AA of the toilet seat 100 shown in FIG. 4, for example.

  As shown in FIG. 1, a toilet seat 100 includes a toilet seat upper plate 1 having a seating surface 1f on which a person sits, a toilet seat lower plate 2 joined to the toilet seat upper plate 1 to form a bottom surface 2b, and the toilet seat upper plate 1 and the toilet seat. A heater unit 4 provided in a toilet seat hollow portion 3 formed of a lower plate 2 and attached to a back portion 1b of the toilet seat upper plate 1. The heater unit 4 includes a conductor and can warm the seating surface 1f by energization.

A side wall portion 5 and a side wall portion 9 are provided at the lower end of the edge portion 13. The side wall 5 and the side wall 9 are provided on the inner peripheral side and the outer peripheral side of the toilet seat 100.

  The side wall portion 9 is adjacent to the toilet seat hollow portion 3. The side wall part 5 is a convex part extending downward from the side wall part 9. Further, the side wall portion 5 is located outside the toilet seat 100 with respect to the side wall portion 9. That is, the side wall part 5 is located farther than the side wall part 9 when viewed from the toilet seat hollow part 3.

  The toilet seat lower plate 2 has an edge 14 in the horizontal direction. And the side wall part 6 and the side wall part 10 are provided in the upper end of the edge part 14. As shown in FIG. The side wall 6 and the side wall 10 are provided on the inner peripheral side and the outer peripheral side of the toilet seat 100.

  The side wall portion 10 is adjacent to the toilet seat hollow portion 3. The side wall part 10 is a convex part extending upward from the side wall part 6. Further, the side wall portion 6 is located outside the toilet seat 100. That is, the side wall part 6 is located farther than the side wall part 10 when viewed from the toilet seat hollow part 3.

FIG. 2 is a cross-sectional view illustrating a welded portion of the toilet seat according to the embodiment of the present invention.
In the following, one of the outer peripheral side and the inner peripheral side of the toilet seat 100 will be described, but the same description can be applied to the outer peripheral side and the inner peripheral side of the other.

The toilet seat 100 is adjacent to the first welded portion 7 in which the side wall portion 5 of the toilet seat upper plate 1 and the side wall portion 6 of the toilet seat lower plate 2 are welded, and the first welded portion 7 via the space portion 8. It has the 2nd welding part 11 by which the side wall part 9 of the board 1 and the side wall part 10 of the toilet seat lower board 2 were welded. The side wall 5 of the toilet seat upper plate 1 and the side wall 6 of the toilet seat lower plate 2 have a cutting surface 12 in which a part of the first welded portion 7 is cut.
The toilet seat upper plate 1 and the toilet seat lower plate 2 may be connected by a method (for example, adhesion) other than welding.

The side wall part 5 has a side surface 150 and a side surface 121. The side surface 121 is bent from the side surface 150 and is provided below the side surface 150.
Further, the side wall portion 6 has a side surface 160 and a side surface 122. The side surface 122 is bent from the side surface 160 and is provided above the side surface 160.
The cutting surface 12 is formed by the side surface 121 and the side surface 122. That is, the side surface 121 and the side surface 122 are connected, for example, without a step, and the side surface 122 is positioned on the extension of the side surface 121.

  With this configuration, the weld seat welded portion is provided with two welded portions, the first welded portion 7 and the second welded portion 11. The first welded portion 7 is formed with a cutting surface 12 cut by cutting. The two welded portions of the first welded portion 7 and the second welded portion 11 can secure the bonding force between the toilet seat upper plate 1 and the toilet seat lower plate 2, and when the user is seated on the toilet seat 100. The strength of the toilet seat 100 that can support the load applied to the toilet seat 100 can be ensured. Further, by providing the first welding portion 7 with the cutting surface 12, it is possible to provide a toilet seat having no gap at the joint portion between the toilet seat upper plate 1 and the toilet seat lower plate 2. By providing the cutting surface 12, the joint between the toilet seat upper plate 1 and the toilet seat lower plate 2 becomes less conspicuous, and the design can be improved.

  For example, in a toilet seat having only one welded portion, if a cutting surface is provided in the welded portion in order to improve the design, it is conceivable that the joining area is reduced by cutting and the joining strength is lowered. On the other hand, in the toilet seat 100 according to the present embodiment, even if the first welded portion 7 is provided with the cutting surface 12 in order to improve the design, the second welded portion 11 is provided to ensure a bonding area. The joint strength of the entire toilet seat can be ensured.

  Further, in the vertical direction, the distance from the seating surface 1 f to the first welded portion 7 is longer than the distance from the bottom surface 2 b to the first welded portion 7. That is, the 1st welding part 7 is located in the downward direction and the outer side of the toilet seat 100, and the cutting surface 12 is also located in the downward direction similarly. Since the cutting surface 12 is positioned below the toilet seat 100, the cutting surface 12 is positioned at a position that is difficult for the user to see, and the cutting surface is difficult to be visually recognized by the user. That is, it is possible to provide a toilet seat that is more aesthetically pleasing.

  Further, the second welded portion 11 is located above and inside the first welded portion 7. When the first welded portion 7 is located on the upper side and the inner side, the second welded portion 11 is likely to receive mainly the load applied to the toilet seat upper plate 1 when the user sits on the toilet seat.

  For example, when the height of the first welded portion 7 and the height of the second welded portion 11 are different from each other, the load applied to the toilet seat upper plate 1 when the user is seated on the toilet seat 100 is mainly used as the second welded portion. 11 can be easily received. For example, the ratio of the load applied to the second welded portion 11 by adjusting the height of the step between the side wall 6 and the side wall 10 and the height of the step between the side wall 5 and the side wall 9. Can be adjusted. At this time, the beauty of the toilet seat 100 can be improved as described above by providing the first welded portion 7 below and outside the toilet seat 100 as in this embodiment.

  Although the load of the whole toilet seat is received by the two welded portions of the first welded portion 7 and the second welded portion 11, mainly the first welded portion 7 has a design surface, the second welded portion 11 has a strength surface, Each has a function to improve.

  FIG. 3 is a cross-sectional view schematically showing the area of the welded portion of the toilet seat according to the first embodiment of the present invention.

  As shown in FIG. 3, the bonding area of the second welded portion 11 is larger than that of the first welded portion 7. For example, the width W2 along the left-right direction of the second welded portion 11 is wider than the width W1 along the left-right direction of the first welded portion 7.

  As described above, the second welded portion 11 has a function of improving the strength surface. By making the bonding area of the second welding part 11 larger than the bonding area of the first welding part 7, the bonding force of the second welding part 11 can be made stronger than the bonding force of the first welding part 7. Thereby, the joining force of the toilet seat upper board 1 and the toilet seat lower board 2 can be improved.

  FIG. 4 is a perspective view schematically illustrating the distribution in the toilet seat circumferential direction of the welded portion of the toilet seat according to the first embodiment of the present invention.

4, the 1st welding part 7 and the 2nd welding part 11 of the inner peripheral side of the toilet seat 100 are shown in figure.
As shown in FIG. 4, in the toilet seat circumferential direction, the first welded portion 7 is provided over the entire region in the circumferential direction. On the other hand, the second welded portion 11 is partially provided in the toilet seat circumferential direction.

  As described above, since the first welded portion 7 has a function of improving the design surface, by providing the first welded portion over the entire region in the toilet seat circumferential direction, high designability can be ensured over the entire region in the circumferential direction.

  On the other hand, the second welding portion 11 can be partially provided in the circumferential direction of the toilet seat to reduce the welding pressure when the toilet seat upper plate 1 and the toilet seat lower plate 2 are welded. That is, by reducing the distribution area of the second welded portion 11, the toilet seat 100 can be reliably welded by a simple molding method.

  FIG. 5 is a perspective view showing the distribution in the toilet seat circumferential direction of the welded portion of another toilet seat according to the first embodiment of the present invention.

  Also in FIG. 5, the 1st welding part 7 and the 2nd welding part 11 of the inner peripheral side of the toilet seat 100 are shown in figure. Moreover, the 1st welding part 7 is provided over the whole area | region of the circumferential direction. On the other hand, the second welded portion 11 is partially provided in the circumferential direction of the toilet seat 100.

  Furthermore, in the example of FIG. 5, the second welded portion 11 is provided more behind the toilet seat 100 than the front of the toilet seat 100 with respect to the center C <b> 1 in the front-rear direction of the toilet seat 100. .

The second welded portion 11 is often provided behind the toilet seat where a load is easily applied when the user is seated on the toilet seat. The load applied to the toilet seat can be supported efficiently.
[Example]
Next, in the embodiment of the present invention, an example of toilet seat cutting will be described.

  FIG. 6 is a cross-sectional view illustrating an example of cutting the welded portion of the toilet seat according to the first embodiment of the present invention. FIG. 6 shows a state of the toilet seat according to the first embodiment before cutting.

  When the side wall part 5 of the toilet seat upper plate 1 and the side wall part 6 of the toilet seat lower plate 2 are joined by welding, burrs are generated at the time of welding, and the welding burr 17 is transferred to the outside of the first welding part 7 and the space part 8. Exposed.

  If the welding burr 17 is exposed to the outside of the first welding part 7 in particular, the user may be injured by touching the welding burr 17 when opening or closing the toilet seat 100 or when sitting. Further, if the welding burr 17 is exposed to the outside of the first welding part 7, the design of the toilet seat 100 is impaired, and it is necessary to remove these welding burr 17.

  As shown in FIG. 7, in order to remove the welding burr 17 exposed to the outside of the first welding part 7, cutting is performed with the processing tool 18.

  In order to perform cutting with the processing tool 18, the first welded portion 7 in which the side wall portion 5 of the toilet seat upper plate 1 and the side wall portion 6 of the toilet seat lower plate 2 are joined, and exposed to the outside of the first welded portion 7. A cutting surface 12 is formed on the first welded portion 7 by bringing the machining tool into contact with the welded burr 17 vertically and performing cutting.

  When the contact of the processing tool 18 varies, the width of the cutting surface 12 may also vary. In order to reduce the variation in the width of the cutting surface 12, the angle (inclination) between the side wall 5 of the toilet seat upper plate 1 and the side wall 6 of the toilet seat lower plate 2 may be set.

  As the angle between the side wall portion 5 of the toilet seat upper plate 1 and the side wall portion 6 of the toilet seat lower plate 2 rises, the variation in the width of the cutting surface 12 increases, and as the angle decreases, the width of the cutting surface 12 varies. Becomes smaller.

  Further, by setting the angle of the side wall portion 5 of the toilet seat upper plate 1 and the side wall portion 6 of the toilet seat lower plate 2 to an angle that is not conspicuous in design adjacent to the vertical angle that is the angle of the cutting surface 12 of the toilet seat, A toilet seat with a more beautiful appearance can be provided.

  Therefore, the angle between the side wall portion 5 of the toilet seat upper plate 1 and the side wall portion 6 of the toilet seat lower plate 2 is set so as to reduce the variation in the cutting width, and adjacent to the vertical angle that is the angle of the cutting surface 12 of the toilet seat. By making the angle inconspicuous in design, it is possible to provide a toilet seat with an excellent aesthetic appearance.
