Description

  The present invention relates to a bathtub having a seat surface on which a person can sit.

  In recent years, bathtubs having a seat surface (stool) on which a person can sit down due to a step formed continuously from the bottom surface have become widespread (for example, Patent Document 1). Accordingly, a whole body bath can be performed if sitting on the bottom surface, and a half body bathing can be performed if sitting on the seat surface, so that the user can select a favorite bathing method without adjusting the amount of hot water in the bathtub. In addition, since the user can take a bath while sitting on the seating surface instead of being crouched on the bottom surface, the comfort can be improved.

  However, in the bathtub as described above, it is assumed that the load is biased toward the seat surface when the user sits on the seat surface. On the other hand, when the seat surface is provided in the bathtub by integral molding, the bottom surface of the bathtub is raised on the back side of the seat surface, and therefore cannot be supported at the same level (height) as the bottom surface. Then, the part with the seating surface is in a cantilever state, and it is assumed that if the weight is applied here, the part of the seating surface is bent or the entire bathtub is tilted. Therefore, in the bathtub of Patent Document 1, a columnar reinforcing member that supports the bathtub is provided at the lower part of the seating surface outside the bathtub and receives the load of the person when sitting on the seating surface.

JP 2008-212182 A

  However, if it is a columnar reinforcement member like patent document 1, since a plurality of members, such as a column and parts which attach it to a bathtub, are needed, it is high-cost and requires work for installation work. . Moreover, in the reinforcement member like patent document 1, since the junction part with a bathtub is only one upper surface of a reinforcement member, it is necessary to enlarge the upper end of a reinforcement member (it enlarges a junction area with a bathtub), and cost. Cause rise. For this reason, the development of a structure capable of increasing the bonding strength with a simple configuration has been desired.

  Furthermore, the support structure on the bathroom side is also affected. If the seating surface is not provided, the bottom surface of the bathtub can be supported in a well-balanced manner at two locations in the long side direction. However, if the reinforcing member is provided under the seating surface, it is necessary to support the reinforcing member under the seating surface in addition to the two locations on the bottom surface, so that a support structure at three locations is required on the bathroom side. Therefore, when mounting a bathtub on a frame, there is a problem that three frames are required.

  The present invention has been made in view of such a problem, and an object thereof is to provide a bathtub capable of reducing cost and simplifying the mounting operation and capable of increasing the bonding strength between the bathtub and the support member. .

  In order to solve the above problems, a typical configuration of a bathtub according to the present invention is a bathtub having a seat surface on which a person can sit, and a bottom surface of the bathtub and a stand standing from the bottom surface. The installation surface and the seat surface at a position higher than the bottom surface are integrally formed continuously, and extend from the back side of the seat surface to the vicinity of the bottom surface along the back side of the installation surface. A support member is provided.

  According to the said structure, the upper end surface of a supporting member supports a seat surface, and can prevent the inclination of a bathtub and the bending of a seat surface. The support member is joined along the back side of the standing surface, and the lower end of the support member extends near the bottom surface. If the lower end of the support member is supported, the load on the seat surface and the load on the entire bathtub are simultaneously supported. can do. Accordingly, the support structure on the bathroom side can be shared, and even if a seating surface is provided, it is not necessary to add a frame, and the cost can be reduced. Further, since the support member is along the back side of the standing surface, the bonding strength between the support member and the bathtub can be easily improved, and the shape and structure of the support member can be simplified. The cost of the member can also be reduced.

  The support member may extend further to the back side of the bottom surface. According to such a configuration, since the support member is arranged to extend to the back side of the bottom surface, the support member is simultaneously joined to the bottom surface and the seat surface of the bathtub. Therefore, it is possible to increase the bonding strength of the support member to the bathtub with a simple configuration as compared with the columnar reinforcing member, and the number of parts does not increase. Thereby, it is possible to reduce the cost and simplify the installation work.

  On the back side of the seating surface, an abutting portion whose angle with respect to the back side of the standing surface is substantially a right angle is formed, and the support member may abut on the abutting portion.

  According to such a configuration, the load applied from the seating surface can be stably received by the support member, and the force in the direction of separating the support member and the contact portion is extremely small. For this reason, the load resistance and durability of a support member can be improved. In addition, it may replace with the angle with respect to the back side of a standing surface, and you may form so that the angle with respect to the axial direction of a supporting member may become a substantially right angle.

  According to the present invention, while providing a seat surface at a position higher than the bottom surface, the supporting member is configured to be simple and have high bonding strength, so that the cost can be reduced and the mounting operation can be simplified. Can be provided.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

(First embodiment)
FIG. 1 is a diagram illustrating a bathtub 100 according to the first embodiment, FIG. 2 is a three-view diagram illustrating a support member, FIG. 3 is a plan view and a bottom view of the bathtub, and FIG. 4 is a bottom perspective view of the bathtub.

  As shown in FIG. 1, the bathtub 100 according to the first embodiment has a side surface 114 erected from the bottom surface 112, so that a so-called bathtub shape is formed. As shown in FIG. 3A, the bathtub 100 has a generally rectangular shape, and a seat surface 124 higher than the bottom surface 112 is provided at one end in the long side direction. A standing surface 122 stands from the bottom surface 112, and a seating surface 124 extends from the upper edge of the standing surface 122. That is, the bathtub 100 includes a bottom surface 112, a side surface 114, a standing surface 122, and a seat surface 124 that are integrally and continuously formed.

  By providing the seat surface 124 at a position higher than the bottom surface 112 in the bathtub 100 as described above, the user can take a bath while sitting on the seat surface 124, and comfort can be improved. In addition, the user can select a preferred bathing method without adjusting the amount of hot water because the user can take a half-body bath by sitting on the seat surface 124 and the whole body bath by sitting on the bottom surface 112.

  As shown in FIG. 1, FIG. 3 (b), and FIG. 4, a foot 132 is joined to the back side 112 a of the bottom surface of the bathtub 100 in the vicinity of one short side (opposite the seating surface 124). The foot 132 includes a placement foot 132a placed on the frame 104 and a positioning foot 132b thicker than the placement foot 132a. The positioning foot 132b is disposed closer to the center than the placement foot 132a. In the present embodiment, the placement foot 132a and the positioning foot 132b are both block-shaped. Then, by placing the placing foot 132 a on the frame 104, the positioning foot 132 b comes into contact with the side surface of the frame 104. Thereby, the movement to the longitudinal direction outer side (left direction of FIG. 1) of the bathtub 100 is suppressed. The mounting foot 132a and the positioning foot 132b are not necessarily separated from each other, and may be configured integrally.

  As shown in FIGS. 1 and 2, the support member 134 is disposed on the back surface 122 a of the standing surface so as to extend from the back surface 124 a of the seat surface to the vicinity of the bottom surface along the back side of the standing surface 122. The support member 134 is a block-shaped structural member. By making the block shape in this way, it is possible to simplify the mold and reduce its cost. The upper end surface 134e of the support member 134 is joined to the back side 124a of the seat surface. In the present embodiment, the bathtub-side surface 134f of the support member 134 is joined to the rear surface 122a of the standing surface. In FIG. 2, hatching indicates a joint surface with the bathtub 100. The bonding can be performed by an adhesive, but may be performed by welding or spray coating.

  Further, in the present embodiment, the support member 134 is placed on the frame 104. Therefore, since the support member 134 also functions as a mounting foot, it is not necessary to provide the mounting foot on the side on which the seat surface 124 is formed on the back side 112a of the bottom surface. Thereby, since such a mounting foot can be omitted, the cost and the number of processes can be reduced. A positioning leg 135 is provided in the vicinity of 134 on the back side of the bottom surface. Thereby, by placing the support member 134 on the frame 104, the movement of the bathtub 100 to the outside in the longitudinal direction (right direction in FIG. 1) is suppressed. That is, the installation stability can be improved by placing the foot 132 and the support member 134 on the frame 104.

  FIG. 5 is a diagram for explaining a frame. As shown in FIG. 5, the bathtub 100 according to this embodiment is placed on a frame 104 connected to a wash floor 102 that constitutes a bathroom wash wash (not shown). The frame 104 is an approximately L-shaped structural member, and is supported by inserting one end of a beam portion 104a on which the bathtub 100 is placed into the wash floor 102, and a leg portion 104b at the other end of the beam portion 104a. It hangs down to the floor of the bathroom. With such a structure, the structure of the frame 104 is simplified and lightened, and positioning is facilitated.

  In this embodiment, the bathtub 100 is placed on the frame 104. However, the present invention is not limited to this, and the bathtub 100 may be placed directly on the floor of the bathroom, or a waterproof pan (not shown). A bathtub side floor) may be installed and placed thereon.

  According to the above configuration, since the support member 134 supports the back side 124a of the seat surface, the support member 134 can receive the load when the user is seated on the seat surface 124. Therefore, it is possible to prevent the seat surface 124 from being bent and to prevent the bathtub 100 from tilting.

  Here, since the support member 134 is joined to both the back side 124a of the seating surface and the back side 122a of the standing surface, the support member 134 can be configured with respect to the bathtub 100 with a simple configuration as compared to the support member having a pillar shape. Bonding strength can be increased. Therefore, the number of parts does not increase, and the cost can be reduced and the mounting work can be simplified.

  Further, in the present embodiment, as shown in the enlarged view in a circle of FIG. 1, the angle θ with respect to the rear side 122a of the standing surface is substantially perpendicular to the portion where the upper end surface 134e of the support member 134 abuts on the rear side 124a of the seating surface. A contact portion 124b is formed. In addition, instead of the angle with respect to the rear side 122a of the standing surface, the angle with respect to the axial direction of the support member 134 may be formed to be substantially a right angle. When the support member 134 is along the back side 122a of the standing surface, these are substantially synonymous.

  Thereby, since the load applied from the seating surface 124 can be stably received by the support member 134, the force in the direction of separating the support member 134 and the contact portion 124b is extremely small. Therefore, the load resistance and durability of the support member 134 can be increased.

  FIG. 6 is a diagram for explaining the configuration of the contact portion 124b. FIG. 6A shows a configuration similar to that in FIG. 1, and the contact portion 124 b is formed so as to rise above the extension line L (one-dot chain line) on the back side 124 a of the seat surface. In FIG. 6B, the abutting portion 124 b is formed so that the side far from the standing surface 122 is raised from the extension line L and the near side is recessed from the extension line L. In FIG. 6C, the entire contact portion 124 b is formed so as to be recessed from the extension line L. Thus, the contact portion 124b only needs to have an angle θ with respect to the back side 122a of the standing surface substantially perpendicular, and the positional relationship with the back side 124a of the seating surface does not matter. In the present embodiment, the contact portion 124b is illustrated as a simple plane, but it may be formed in a concavo-convex shape so as to mesh with the upper end surface 134e of the support member 134.

  As described above, according to the bathtub 100 according to the first embodiment, the upper end surface 134e of the support member 134 supports the seat surface 124, whereby the inclination of the bathtub 100 and the deflection of the seat surface 124 can be prevented. . The support member 134 is joined along the rear side 122a of the standing surface, and the lower end thereof extends in the vicinity of the bottom surface 112. Thus, if the lower end of the support member 134 is supported, the load on the seat surface 124 and the bathtub 100 total loads can be supported simultaneously. Therefore, the support structure on the bathroom side can be made common, and even if the seating surface 124 is provided, it is not necessary to add the frame 104, and the cost can be reduced. Further, since the support member 134 is along the rear side 122a of the standing surface, the bonding strength between the support member 134 and the bathtub 100 can be easily improved, and the shape and structure of the support member 134 can be simplified. Therefore, the cost of the support member 134 can be reduced.

(Second Embodiment)
FIG. 7 is a diagram illustrating a bathtub according to the second embodiment, FIG. 8 is a five-side view illustrating a support member, and FIG. 9 is a bottom perspective view of the bathtub. In addition, about the element substantially the same as that of the bathtub 100 of 1st Embodiment, or the same element, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The support member 134 included in the bathtub 100 of the first embodiment is joined to the back side 124a of the seating surface and the back side 122a of the standing surface in a block shape, whereas the support member 234 included in the bathtub 200 of the second embodiment is In addition to the back surface 124a of the seating surface and the back surface 122a of the standing surface, it is joined to the back surface 112a of the bottom surface.

  Specifically, as shown in FIGS. 7, 8, and 9, the support member 234 is disposed on the back side 122 a of the standing surface so as to extend from the back side 124 a of the seating surface to the back side 112 a of the bottom surface. The support member 234 is a generally L-shaped structural member, and includes a column portion 234a disposed along the back side 122a of the standing surface and a beam portion 234b disposed along the back side 112a of the bottom surface. Yes. The upper end surface 234e of the column portion 234a is joined to the back side 124a of the seating surface. The upper surface of the beam portion 234b is joined to the back side 112a of the bottom surface. In the present embodiment, the bathtub-side surface 234f of the column portion 234a is joined to the rear surface 122a of the standing surface. In FIG. 8, hatching indicates a joint surface with the bathtub 200. Similar to the support member 134 of the first embodiment, the bonding may be performed by an adhesive, or may be performed by welding or spray coating.

  On the bottom surface of the beam portion 234 b, a placement surface 234 c placed on the frame 104 and a convex portion 234 d that contacts the side surface of the frame 104 are formed. The convex portion 234d is disposed on the center side of the bathtub 100 with respect to the placement surface 234c, and the placement surface 234c is placed on the frame 104, thereby moving the bathtub 100 outward in the longitudinal direction (right direction in FIG. 1). Is suppressed. That is, the installation stability can be improved by placing the foot 132 and the support member 234 on the frame 104.

  When the support member 234 is configured by the column portion 234a and the beam portion 234b as in the present embodiment, the column portion 234a of the support member 234 supports the back side 124a of the seating surface. Thereby, the support member 234 can receive the load when the user is seated on the seating surface 124. Therefore, the support member 234 can also prevent the seat surface 124 from being bent and prevent the bathtub 200 from tilting.

  Here, since both ends of the support member 234 are joined to both the back side 112a of the bottom surface and the back side 124a of the seating surface, the support member 234 can be attached to the bathtub 100 with a simple configuration as compared to the support member having a pillar shape. Bonding strength can be increased. Therefore, the number of parts does not increase, and the cost can be reduced and the mounting work can be simplified.

  Further, according to the above configuration, the support member 234 is arranged to extend from the back surface 124 a of the seat surface to the back surface 112 a of the bottom surface, so that the support member 234 can be applied to the load on the seat surface 124 and the bottom surface 112 (bathtub) by one frame 104. The whole load is supported at the same time. In other words, two frames of the seating surface 124 and the bottom surface 112 can be received by one frame 104. Thereby, the support structure on the bathroom side can be made common, and even if the seating surface 124 is provided, it is not necessary to add the frame 104, and an increase in cost can be suppressed.

  As described above, according to the bathtub 200 according to the present embodiment, the load on the seating surface 124 and the bottom surface 112 (the entire bathtub) can be simultaneously supported by the support member 234. For this reason, there is no need to provide a conventional strut-shaped reinforcing member under the seating surface 124, which makes it possible to reduce costs and simplify the mounting operation. Further, the support member 234 is disposed up to the back side 112a of the bottom surface and is also joined to the back side 112a of the bottom surface, so that the joining strength can be further improved.

  Needless to say, the present invention is not limited to the above embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be applied to a bathtub having a seat surface on which a person can sit.
