Description

  The present invention relates to a bathtub, and more specifically, a bather is formed with one shallow side in the longitudinal direction so that the bather can use for half-body bathing, and the bottom is a shallow bottom with a shallow bottom and a deep bottom adjacent to the shallow bottom. It is related with the bathtub currently formed in the deep bottom part.

Conventionally, this type of bathtub is usually formed so that four legs are provided at the deep bottom portion, and one leg is added at the center of the lower surface of the shallow bottom portion and is supported by five legs.
Conventionally, as described in Patent Document 1, for example, there is a bathtub in which a pair of support members are provided on the lower surface of the shallow bottom portion and the shallow bottom portion is supported by two legs.

By the way, in the case of this kind of bathtub, if the shallow bottom part is supported by one leg and the five-legged structure is combined with the deep bottom part, it is difficult to level out because the number of legs increases compared to four legs. In addition, the cost is inevitable.
Moreover, when the number of legs increases, the plane location required for the waterproofing pan for bathtub mounting increases, and it is necessary to form many flat parts of a waterproofing pan. Moreover, at present, the position of the legs of this kind of stool with a stool is generally asymmetric in the LR specification (specification form in which the stool is on the left side or the right side during installation). In other words, the position of the legs of this kind of stool with a stool is asymmetric when the elevation of the bathtub is viewed from the longitudinal direction. Therefore, in these respects as well, the increase in the number of legs has led to an increase in the cost of equipment around the bathtub, and there is a disadvantage that the drainage flow is changed and the drainage cannot be performed in an orderly manner.
In the case of this kind of bathtub, the length of the leg that supports the shallow bottom is usually long. Therefore, if the two legs are simply provided at the shallow bottom as in the bathtub according to Patent Document 1, the standing state and the standing posture of the legs are unstable, and the vibration resistance against shaking along the longitudinal direction of the bathtub is weak. There was a problem of becoming.
JP 2002-112911 A

The present invention has been proposed in view of such conventional situations.
Therefore, the technical problem to be solved by the present invention is to stabilize the support and reduce the cost in the bathtub with a stool, and to share and share the waterproof pan for installing the bathtub even when the LR specifications are different. Providing a bathtub formed to improve vibration resistance by reducing the cost and ordering the flow of drainage, and stabilizing and solidifying the standing state of the legs that support the shallow bottom. It is in.

The present invention employs the following technical means in order to solve the above problems.
That is, according to the present invention, as shown in FIG. 1 and the like, one side in the longitudinal direction of the bathtub is formed shallow, the bottom 1 has a shallow bottom 2 and a deep deep bottom 3 adjacent to the shallow 2. The leg 4 supporting the shallow bottom portion 2 is positioned at an angle formed by the vertical surface 8 between the shallow bottom portion 2 and the deep bottom portion 3 and the lower surface of the shallow bottom portion 2. The position of the center of gravity on the ground contact surface of the leg 7 that supports the deep bottom 3 is provided on the lower surface of the shallow bottom 2, and the length of the edge of the bathtub is divided into two equal parts when viewed from the flat side. The rib 4 is provided at a position symmetrical to the center of gravity of the ground contact surface of the leg 4 that supports the shallow bottom portion 2 via the center line L, and is connected to the bottom surface 1 and is connected to the shallow bottom portion 2 and the deep bottom portion 3 for reinforcement. 5, and a leg 4 that supports the shallow bottom portion 2 is fixed to the rib 5 (Claim 1).
In the present invention, the number and form of the legs 4 and 7 and the form of the ribs 5 are arbitrary.

In addition, as shown in FIG. 4 and the like, the present invention is formed such that one side in the longitudinal direction of the bathtub is shallow, the bottom 1 has a shallow bottom 2 and a deep deep bottom 3 adjacent to the shallow 2. And a reinforcing rib 5 is provided on the bottom surface 1 so as to be connected to the shallow bottom portion 2 and the deep bottom portion 3, and the rib 5 is vertically disposed between the shallow bottom portion 2 and the deep bottom portion 3. The position corresponding to the angle formed by the surface 8 and the lower surface of the shallow bottom portion 2 is extended downward, and the extended portion is grounded and formed on the leg 4 that supports the shallow bottom portion 2. The center of gravity of the leg 7 that supports 3 on the ground contact surface supports the shallow bottom 2 via a center line L that divides the length of the edge of the bathtub into left and right when the bathtub is viewed horizontally from the plane. 4 is provided at a position symmetrical to the position of the center of gravity on the ground contact surface (claim 2).
In the case of the present invention, not only the bottom surface 1 can be reinforced by the rib 5 but also the rib 5 has a function of supporting the shallow bottom portion 2, so that it is not necessary to provide a special leg for the shallow bottom portion 2. Can be reduced.

Further, in the case of the present invention, it is preferable that the rib 5a located in the shallow bottom portion 2 is formed in a substantially triangular shape when viewed in the longitudinal longitudinal section of the bathtub .
Because, according to this, the rib 5 is formed in a triangular fin shape over the vertical surface 8 at the boundary between the shallow bottom portion 2 and the deep bottom portion 3 and the lower surface of the shallow bottom portion 2, and it is possible to save the forming material while obtaining high reinforcing strength. Because.

Further, in the case of the present invention, it is preferable that the ribs 5a located on the shallow bottom portion 2 are formed in a pair of parallel plates .
This is because the strength can be increased without increasing the thickness of the rib 5 and the leg 4 can be firmly attached with the leg 4 supporting the shallow bottom portion 2 interposed therebetween.

In the present invention, it is preferable that the rib 5 is integrally formed with the bottom surface 1 (Claim 4 ).
This is because the strength can be increased and the distortion and deformation of the bottom surface 1 can be reliably prevented as compared with the case where the rib 5 is retrofitted to the bottom surface 1 using an adhesive or the like.

In this way, the bathtub is formed such that one side in the longitudinal direction of the bathtub is shallow, and the bottom surface is formed into a shallow bottom portion and a deep deep bottom portion adjacent to the shallow bottom portion. The legs supporting the shallow bottom are positioned on the corner formed by the vertical surface between the shallow bottom and the deep bottom and the lower surface of the shallow bottom, and provided on the lower surface of the shallow bottom to support the deep bottom. The position of the center of gravity on the ground contact surface is symmetrical to the position of the center of gravity on the ground contact surface of the leg that supports the shallow bottom through a center line that bisects the length of the edge of the bathtub when viewed horizontally from the plane. In addition, the ribs for reinforcement are provided on the bottom surface so as to be connected to the shallow bottom portion and the deep bottom portion, and the legs supporting the shallow bottom portion are fixed to the ribs.
Therefore, according to this invention, the bathtub with a stool of the stable state can be provided, suppressing cost.
In addition, the present invention can provide a bathtub having the same leg position regardless of whether the position of the shallow bottom portion (stool portion) is on the left or right side. Therefore, according to this, even when the LR specifications are different, the waterproof pan on which the bathtub is placed can be shared and shared, and there is no loss, and the cost of this type of waterproof pan can be reduced. Moreover, according to this, the flow of waste water can be made the same by LR specification, and the flow of waste water can be ordered.
Further, according to the present invention, as described above, the legs supporting the shallow bottom portion are provided on the lower surface of the shallow bottom portion, positioned at the corner formed by the vertical surface between the shallow bottom portion and the deep bottom portion and the lower surface of the shallow bottom portion. Therefore, according to this, the leg which supports a shallow bottom part can be provided firmly and stably, and the vibration resistance with respect to the shake and vibration along the longitudinal direction of a bathtub can be improved.
Further, according to the present invention, not only the bottom surface can be reinforced by the rib, but also the load can be efficiently transmitted to the leg supporting the shallow bottom portion via the rib, and the fixed state of the leg supporting the shallow bottom portion can be firmly fixed.

Hereinafter, the best mode for carrying out the present invention will be described.
