[Bathroom chair]
With reference to FIGS. 1-8, the structure of the chair 1 for bathrooms is demonstrated. The front / rear / left / right direction of the bathroom chair 1 is defined as the front / rear / left / right direction when seated.
The bathroom chair 1 is a chair-like structure including a seat surface 10 and legs 20 that support the seat surface 10. The bathroom chair 1 has a bilaterally symmetrical shape with the center in the left-right direction as the center.
As a material constituting the bathroom chair 1, any material that can withstand use in the bathroom can be used. Examples thereof include plastic materials such as polypropylene and ABS resin, and wooden materials such as straw and cedar.

The seat surface 10 is a top plate surface constituting a part of the bathroom chair 1 and is a flat plate-like portion formed in a substantially rectangular shape in plan view. The seat surface 10 has a thickness that can secure a strength that can withstand the use of the bathroom chair 1.
When using the bathroom chair 1, the user sits on the seat surface 10. Therefore, the seat surface 10 is in close contact with the user's buttocks, the back of the thigh, the waistline, and the like.

A backrest 11 is formed at the rear end of the seating surface 10. The backrest 11 is formed in a shape that protrudes upward from the seating surface 10 and gradually warps toward the rear end. That is, the seat surface 10 has a shape in which the back is warped in the side view by the backrest 11. Thus, the stability when seated can be improved by forming the backrest 11 on the seating surface 10.
Further, the rear end portion of the seating surface 10 is formed in a loosely curved shape from the central portion to both side end portions so that the central portion is located most rearward in plan view. Thus, by having a curved shape at the rear end portion of the seating surface 10, it is possible to follow the shape of the waistline and improve the fit when seated.

The leg 20 is configured as a bottom part of the bathroom chair 1, that is, a grounding part with the floor, and is configured as a support part that receives a load applied to the seating surface 10. Rubber (not shown) is disposed at the ground contact portion between the leg 20 and the floor, and consideration is given so as not to damage the floor surface by absorbing the impact applied to the bathroom chair 1.
The leg 20 is formed as a substantially rectangular tube-shaped portion corresponding to the shape of the seating surface 10. The leg 20 of the present embodiment is configured as a cylindrical wall surface extending downward from the periphery of the seat surface 10.

As shown in FIG. 2, drainage and ventilation openings 21 and 21 are provided on the side surfaces of the legs 20. Further, as shown in FIG. 3, a drainage / ventilation opening 22 is similarly provided on the front surface of the leg 20. These openings 21 and 22 are provided inside the legs 20 for discharging water flowing into the inner periphery of the legs 20 to the outside during bathing and when the bathroom chair 1 is left in the bathroom after bathing. An opening for ventilation through the air.
In this way, by providing an opening that communicates the inside and the outside on the outer surface of the leg 20, air permeability inside the leg 20 formed in a cylindrical shape can be ensured. Note that any two openings at the bottom of the outer surface of the leg 20 may be provided as long as sufficient air permeability can be secured.

The openings 21 and 21 provided on the side surface of the leg 20 are provided on the bottom surface side of the bathroom chair 1 and are formed in a substantially right triangle shape in a side view. More specifically, the opening 21 is constituted by a vertical cutout located on the front side of the bathroom chair 1 and an oblique cutout that inclines downward from the upper end toward the rear.

Therefore, a sense of stability and a feeling of use at the time of sitting can be improved.

  The leg 20 may have any shape that can withstand the use of the bathroom chair 1, that is, a shape that can support the seating surface 10 with sufficient strength, and may be formed in a column shape extending in the vertical direction. As described above, when a shape other than the cylindrical shape is adopted, it is not necessary to provide the drainage / ventilation openings 21 and 22, and the recess 23 only needs to be provided on the front end surface of the seat surface 10.

[Locking hole]
As shown in FIG. 4, the seating surface 10 is provided with a locking hole 30.
The locking hole 30 is provided penetrating in the thickness direction (vertical direction) of the seat surface 10. The locking hole 30 is a through hole having a shape that is long in the left-right direction and a predetermined width in the front-rear direction. More specifically, the locking hole 30 includes a front end side 31 and a rear end side 32 that linearly extend in the left-right direction, and both ends in the left-right direction of the rear end side 32 toward both ends in the left-right direction of the front end side 31. It is delimited by the extended arc sides 33 and 33.

The front end side 31 is a straight side extending in the left-right direction in the front-rear center portion of the seating surface 10 and has a length of about one-half to three-fourths of the length of the seating surface 10 in the left-right direction. Provided.
The rear end side 32 is a straight side provided in the left-right direction behind the front end side 31 by a predetermined distance, and is about one-third to two-thirds of the length of the seating surface 10 in the left-right direction. Provided in length.
That is, the extension length of the rear end side 32 is set to be shorter than the extension length of the front end side 31, and the both side ends of the rear end side 32 and the both side ends of the front end side 31 are arcuate. The sides 33 and 33 are connected.

The arc sides 33 and 33 are formed as a part of a great circle centered on a point located in front of the central portion of the seating surface 10. In other words, the arc sides 33 and 33 are formed as arcs cut out by points intersecting the front end side 31 and the rear end side 32 in a circle centered on a predetermined position.
The arc sides 33 and 33 do not have to be formed as strict arcs, and may have a curved shape close to an arc shape. For example, as shown in FIG. 8, the shape of the arc sides 33, 33 is a curved shape that smoothly connects both ends of the front end side 31 and the rear end side 32, thereby suppressing a decrease in strength of the locking hole 30. .

Here, the left and right lengths of the front end side 31 and the rear end side 32 and the interval between the front end side 31 and the rear end side 32 are matters that determine the opening area of the locking hole 30. Determine the area to be cut out. For this reason, it is preferable that these are set as appropriate in consideration of the strength of the seating surface 10, the function of the locking holes 30, and the like after securing the function of the locking holes 30 described later.
For example, in order to secure the function of the locking hole 30, the length of the front end side 31 and the rear end side 32 is preferably at least half of the length in the left-right direction of the seat surface 10. In order to ensure the strength, it is preferable to set the opening area as small as possible.

In addition, regarding the formation position of the locking hole 30 on the seating surface 10, in consideration of drainage on the seating surface 10, the locking hole 30 may be provided so as to include the position that is the lowest point of the seating surface 10. preferable.
For example, when the shape of the seating surface 10 is formed in a concave shape according to the shape of the buttock, the water accumulated on the upper surface of the seating surface 10 can be collected in the locking hole 30 by providing the locking hole 30 at the bottom. Good drainage can be realized.

[Combination of bathroom chair and basin]
The basin 2 can be combined with the bathroom chair 1 having the locking hole 30 configured as described above (see FIGS. 9 to 11).
The basin 2 is a circular basin having a general container shape, and has an edge 3 that extends outward from the peripheral edge of the opening of the container. The edge 3 is a portion that becomes a handle when the basin 2 is used, and is formed as a plane substantially parallel to the bottom of the basin 2.
As such a basin 2, a generally sold basin or a dedicated product for the bathroom chair 1 may be employed. As a dedicated product, for example, it may be a combination that takes into account the design (shape, color, pattern, etc.) of the bathroom chair 1 and the washbasin 2, or from a part of the edge 3 of the washbasin 2. A protrusion corresponding to the shape of the locking hole 30 may be formed to protrude.

Next, with reference to FIG.9 and FIG.10, description is given of the relationship between the washbasin 2 and the locking hole 30 of the bathroom chair 1 when the washbasin 2 is set to tilt forward of the bathroom chair 1. FIG. To do.
FIG. 9 is a reference diagram showing a state in which the bathroom chair 1 is used, and is a perspective view showing a state in which the basin 2 is set in a forward leaning posture. FIG. 10 is an enlarged perspective view showing an engaged state between the bathroom chair 1 and the basin 2. FIG. 10 (a) is a front perspective view and FIG. 10 (b) is a rear perspective view.

  As shown in FIG. 9, the washbasin 2 is engaged with the engagement hole 30 in a state where a part of the washbasin 2 is inserted into the bathroom chair 1 through the engagement hole 30. Set to 1. At this time, the basin 2 is set so as to be substantially bilaterally symmetric about the left and right central portion of the bathroom chair 1, but it is not necessary to be strictly bilaterally symmetric. It can be set at an arbitrary position according to the size / width, the size / thickness of the basin 2, and the like.

As shown in FIG. 10A, the front end side 31 of the locking hole 30 and the two points P1 and P2 of the edge 3 of the basin 2 are in contact with each other. As shown in FIG. 10B, the rear end side 32 of the locking hole 30 and the point P3 on the outer surface of the basin 2 are in contact with each other. In other words, the side of the basin 2 on the tilting direction side (front end side 31) and the basin 2 are in contact with each other at the edge 3 of the basin 2, so that they contact at two points, and the side opposite to the tilting direction (rear end) The side 32) and the basin 2 are in contact at one point.
Thus, the washbasin 2 is supported by the locking hole 30 by the three points of the two points P1 and P2 on the edge 3 of the washbasin 2 and the point P3 on the outer surface side. More specifically, a downward moment is applied to the points P1 and P2 due to the weight of the basin 2, and an upward moment is applied to the point P3, and the moments and points applied to these points P1 and P2 are applied. The basin 2 is engaged in a non-rotatable manner by balancing the moments applied to P3.
In this way, by inserting the edge 3 of the basin 2 from the front side with respect to the locking hole 30 with the opening of the basin 2 facing downward, in a forward inclined posture as shown in FIGS. Locking is possible.

As described above, the basin 2 can be combined with the locking hole 30 of the bathroom chair 1 by a simple operation of inserting the basin 2 into the locking hole 30.
In addition, since the circular shape of the basin 2 corresponds to the arc shape of the arc sides 33 and 33 of the locking hole 30, a point for supporting the basin 2 may also be present on the arc sides 33 and 33. The stability of the basin 2 set on the bathroom chair 1 can be improved. In particular, it is effective when a large basin is adopted as the basin 2.
Furthermore, by providing the arc sides 33 and 33 at the side end of the locking hole 30, the basin 2 can be engaged with the locking hole 30 in a state along the circular shape of the basin 2. Thereby, the latching hole 30 can be made into a required minimum opening area, and the strength reduction of the seat surface 10 can be suppressed.
Thus, when the basin 2 is inserted into the locking hole 30, the circular shape of the basin 2 is inserted along the arc sides 33 and 33 of the locking hole 30, so that it is physically and visually visible. Even natural settings are possible.

Since the seating surface 10 of the bathroom chair 1 is provided with the locking hole 30, the water accumulated in the seating surface 10 flows downward through the locking hole 30. In other words, the locking hole 30 has a function as a conventional draining hole.
In addition, by setting the bathroom chair 1 with the opening of the basin 2 facing upside down, the water remaining in the basin 2 flows down through the locking holes 30, thereby draining the basin 2. While improving, the retention of the water | moisture content in the contact part of the washbasin 2 and the bathroom chair 1 can be prevented.
As a result, after using the bathroom chair 1 and the basin 2 (after bathing), by setting the basin 2 on the bathroom chair 1, good drainage is realized, and in the bathroom chair 1 and basin 2 Mold generation can be suppressed. Moreover, the bathroom chair 1 and the wash basin 2 can be stored integrally, and space saving in the bathroom, a tidy appearance, and a clean feeling can be realized.

[Another form of combination of bathroom chair and basin]
Further, as shown in FIG. 11, the basin 2 can be set in the bathroom chair 1 by inserting the basin 2 into the locking hole 30 in the opposite direction to the posture shown in FIGS. 9 and 10. is there. That is, in addition to the forward leaning posture, the washbasin 2 can be set on the bathroom chair 1 in the backward leaning posture.
In this case as well, the basin 2 is locked by the front end side 31 and the rear end side 32 of the locking hole 30, and the basin 2 is set to the bathroom chair 1 in a tilted posture, as in the operation shown in FIG. . At this time, the basin 2 is inserted from the rear side into the locking hole 30 of the bathroom chair 1 with the opening facing downward.
In this embodiment, as shown in FIG. 11, when the basin 2 is set on the bathroom chair 1 in a backward tilted posture, when the force from above is applied to the basin 2, the edge 3 of the basin 2 is Since it can move forward along the arc sides 33 and 33, the force applied to the seating surface 10 (particularly the locking hole 30) can be dispersed, and the strength is not impaired.

In the embodiment described above, the front basin 31 and the rear side of the locking hole 30 are used to insert the basin 2 from the front side and the rear side of the bathroom chair 1 and set the basin 2 in the forward tilt posture and the rear tilt posture. The end side 32 is a straight line extending in the left-right direction.
However, when the insertion direction of the basin 2, that is, the tilting direction is limited to either the forward tilt or the rear tilt, the side opposite to the tilted side (side that contacts the outer surface of the basin 2) It is good also as a structure which increases a contact point with the washbasin 2 by forming in a curved shape or a bending shape suitably. Thus, the washbasin 2 can be more stably latched by increasing a contact point.

[Another Embodiment of Locking Hole]
In the above embodiment, the configuration in which either the forward tilting posture or the rearward tilting posture can be selected as the installation posture of the basin 2 with respect to the locking hole 30 is shown. As shown, the entire locking hole 30 may be formed in an arc shape.
At this time, the arc shape of the locking hole 30 is preferably a shape corresponding to the circular shape of the basin 2. In consideration of the operation of inserting the washbasin 2 into the locking hole 30, it is preferable to set the diameter of the arc on the rear end side to be larger than the diameter of the arc on the front end side.

[Preferred Embodiment of Locking Hole]
As shown in FIG. 13, it is preferable that ribs 35 are provided downward from the peripheral edge of the locking hole 30. The rib 35 is provided so as to protrude downward from the inner surface of the seat surface 10. The rib 35 functions as a reinforcing portion that supplements the strength of a part of the seat surface 10 cut out by the locking hole 30.
In addition, it is preferable that the rib 35 is provided in the perimeter part of the latching hole 30 from a viewpoint as a reinforcement member, and it may protrude from the inner surface of the seat surface 10 in sufficient downward direction. preferable. Further, the rib 35 may be formed as an inclined surface according to the inclination of the basin 2.

  In addition, although it is preferable to provide the locking hole 30 in the seat surface 10 from the viewpoint of appearance aesthetics and strength, it may be provided in the leg 20. In this case as well, it is preferably formed so that the basin 2 can be set upside down and formed as a locking hole having a shape corresponding to the shape of the basin 2.

  In the embodiment described above, the planar shape of the seating surface 10 and the planar view shape of the legs 20 are substantially rectangular, but the present invention is not limited to this, and may be an elliptical shape, a circular shape, or the like. By providing, it is possible to implement the present invention.
