Abstract

We offer a footbath device that prioritizes convenience, allowing users to easily operate the hot water storage and drainage functions, enabling them to enjoy a footbath while showering. [Solution] A footbath is configured such that a chair section 1 for sitting and a bathtub section 2 for using the feet can be connected. The chair section has a raised section above the seating surface and a leg section 4 below the seating surface. The bathtub section has a foot insertion section 6. One side facing the chair section is cut off above the seating surface, and below the seating surface, it has an opening and closing door that closes when the chair section and the bathtub section are connected. The opening and closing door serves as a connecting part when connecting the chair section and the bathtub section, with a connecting protrusion at the upper end of the bathtub section and a connecting recess at the upper end of the chair section.

Description

Technical Field

[0001] The present invention relates to a foot bath device that enables simple operation of hot water storage and drainage, allows a person sitting on a chair to take a shower bath, and can be converted into a foot bath by immersing a hot water tank closely attached to the chair part, which can be used not only by healthy people but also by those who need to be closely attached to the chair part.

Background Art

[0002] From examples where shower baths other than bathing are increasing and shower baths are recommended not only for healthy people but also for those who avoid bathing, a hot water tank that allows a person sitting on a chair to immerse up to the waist and knees is provided, enabling simple operation of hot water storage and drainage by oneself or with assistance in a timely manner, converting the shower bath into a foot bath, and allowing immersion in the hot water tank that is made into a joined body closely attached to the chair.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The applicant is the one who received the prior art. Document 1 describes a seated shower bath, and the footbath using the water tub that is pulled out from under the chair and used to immerse the lower legs is problematic because, after use, the chair and water tub are not raised up to the waist and above the knees, and sitting in Document 1 lacks stability, limiting the footbath to the lower legs. In Document 2, sitting on the seat involves straddling a raised edge, which is burdensome for the operation of storing and replacing the water using a drain plate attached to the front side wall. To address the problems in an integrated bathroom, this application aims to solve the problems by placing the feet in the water tub, which is raised in the same way as the chair, and filling it with water using the shower bath while keeping it in close contact with the chair, and adjusting the water storage and drainage to convert the shower bath into a footbath. [Means for solving the problem]

[0006] A footbath device configured to connect a seating chair and a footbath bath, wherein the seating chair has a raised upper edge on the seating surface and legs at the bottom of the seating surface, and the heights of the three sides excluding the footrest area, which is at the same height as the seating surface, are raised to match, the footbath bath is placed opposite the seating chair, and connecting recesses and connecting protrusions are attached to the raised ends of both, and a discharge door is provided that closes by fitting into the tightly joined surface of the seating chair and the footbath bath, and when the tightness is released the discharge door opens to drain the water, the seating chair and the footbath bath are joined together, the connecting recess has a circular part when viewed from the side, and the connecting protrusion fits into the circular part when viewed from the side, and the connecting recess and the connecting protrusion are joined in a loose fit. [Effects of the Invention]

[0007] As described above, in a shower bath where one can soak their feet while seated, the connecting recess is attached to the upper end of the raised part of the chair with legs, forming a contact surface with the seating front. The bathtub section, which has a footrest at the same height as the seat of the chair, is also raised on three sides, and a drain is positioned in the center of the footrest of the bathtub section, facing the raised part of the chair section at a uniform height. The connecting recess and connecting protrusion are attached and inserted at each end of the raised part, and the connecting surface of the bathtub section, into which the connecting protrusion inserted into the recess of the chair section is inserted, is equipped with a self-opening and closing drain door, thereby realizing a foot bath that allows one to soak their feet while showering. [Brief explanation of the drawing]

[0008] [Figure 1] A perspective view of the chair section and the bathtub section before joining them together. [Figure 2] Enlarged view of the joint recess in the chair section and the joint protrusion in the bathtub section. [Figure 3] A plan view of the bathtub section, which is in close contact with the seat of the chair. [Figure 4] Side cross-sectional view of the chair section and the bathtub section. [Modes for carrying out the invention]

[0009] The device consists of a raised chair section that the user sits on, a footrest section with a seat height that matches the height of the chair section, and a bathtub section that is joined to the chair section. The joint recess attached to the upper edge of the chair section and the joint protrusion at the upper edge of the raised bathtub section are fitted into the recess that serves as the receiver for the chair section. When the bathtub section is moved parallel to the floor, the joint is released and at the same time, a discharge door provided on the bottom contact surface of the joint opens, allowing the stored water to be discharged. By repeating the process of refilling the bathtub, the device becomes a footbath that allows users to soak their feet in a footbath instead of taking a shower. Furthermore, if wheels are attached to the legs of the chair section, it can also be used as a simple wheelchair by gripping the rear of the seat.

[0010] In this footbath, the chair and the bathtub are joined together. The chair and the bathtub are joined together, and the circular protrusions are inserted into the joint recesses on both sides of the raised ends of the chair, excluding the footrest, by parallel movement to connect them and create a tight seal. The bottom of the bathtub opens with water pressure when the seal is released while the top remains connected, allowing the water to drain. The bottom closes when the chair and the bathtub are reconnected, allowing the bathtub to continue filling with water. When the bottom moves without leaving the floor, the circular protrusions that are connected to the joint protrusions rotate with the movement of the bottom, causing the circular part to descend and loosely fit into the recess. The chair and the bathtub are in close contact to fill with water, and when the seal is released, the discharge door is released and the water drains, allowing the footbath to be used. [Examples]

[0011] An embodiment is described below in accordance with the attached drawings. The chair portion 1 has a raised section around the waist of the seat surface where the user sits, and the chair portion 1 has legs formed below the seat surface. The joint recess (a) of the chair portion 1 is positioned at the upper edge of the chair portion 1, and the joint protrusion (b) is fitted into the joint at the upper edge of the hot water tank portion 2. As the bottom of the contact surface 3 of the hot water tank portion 2 is released, the discharge door 7 is opened and the hot water is drained. A drain section for reducing the amount of stored hot water is also provided. The hot water tank portion 2, which is in close contact with the chair portion 1, is filled with hot water for showering, the stored water is drained, and the bathtub is re-closed to store hot water, and the draining of the hot water tank is repeated to provide a footbath that can be used for immersion.
