Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improvement of a safety grip installed on the inner wall surface of a bathtub.

(Prior art and its problems) Conventionally, safety grips have been installed on the inner wall of bathtubs, but conventional safety grips are made of metal and installed at the upper part of the bathtub wall. Particularly in winter, the safety grip is cold to the touch when taking a bath, and there is a problem in that the safety grip does not function satisfactorily.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide a bathtub equipped with a safety grip that can be used satisfactorily even in winter. , the gist of which is a safety grip installed on the upper part of the inner wall surface of a bathtub, in which a lower part forms a heat absorption part,
At least the heat radiating part of the heat pipe whose upper part forms the heat radiating part is incorporated, and the heat absorbing part of the heat pipe is disposed below the hot water level in the bathtub.

(Function) A heat pipe is built into the safety grip installed in the bathtub, and this heat pipe consists of a heat absorption part at the bottom and a heat radiation part at the top. By placing it below the water level of the bathtub,
The heat absorbing part of the heat pipe is heated by the temperature of the hot water, and the fluorocarbon gas sealed in the heat pipe is vaporized, and heat is emitted in the heat radiating part.The heat emitted from the heat radiating part warms the safety grip, so the safety grip - The grip is kept at an appropriate temperature, so when you touch the safety grip in winter, you do not feel cold, and you can use the safety grip well.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 4 show a first embodiment, and in the figures, a safety grip 2 installed in an inclined manner in the upper part of the inner wall surface of the bathtub 1 near the handrail portion 1a is made of, for example, cast metal. It is made of metal, and is formed into a substantially U-shape by support parts 2a, 2a protruding from the wall surface of the bathtub 1, and a grip part 2b that can be held by the bather with his or her hand. In this example, a hollow hole 3 is formed in the grip portion 2b of the safety grip 2 in the longitudinal direction, and the lower end of the hollow hole 3 becomes a through hole 3a communicating with the outside. The structure is such that a cap screw 5 can be screwed into this through hole 3a.
Therefore, the heat pipe 4 is passed through the hollow hole 3.
The heat pipe 4 can be installed in the hollow hole 3 by inserting it from the side a, and then the filler B is filled around the heat pipe 4 from the through hole 3a side to fix the heat pipe 4, and the heat pipe 4 is fixed in the through hole 3a. By screwing the cap screw 5 into the handle 2b, the heat pipe 4 can be arranged in a concealed manner.

The heat pipe 4 is formed of a hollow tube such as aluminum, stainless steel, or copper, and has fluorocarbon gas sealed inside, and the lower end of the heat pipe 4 is a heat absorbing tube filled with liquefied fluorocarbon gas. The upper end part serves as a heat radiating part from which the vaporized fluorocarbon gas radiates heat from the heat absorbing part.

In this example, since the safety grip 2 has a considerable length in the vertical direction, the lower end of the safety grip 2 is placed below the water level in the bathtub 1, for example. If this is done, when the bathtub 1 is filled with hot water, the lower part of the safety grip 2 will be immersed in the hot water, and the hot water will heat the heat absorbing part at the lower part of the heat pipe 4. The fluorocarbon gas absorbs heat and evaporates, and the heat can be transferred to the upper heat dissipation section, that is, the upper part of the safety grip 2, and the safety grip 2 is well heated by the heat pipe 4. be done. Therefore, if the lower end of the safety grip 2 is in contact with the hot water surface, the entire safety grip 2 will be well heated, and the bather can use the safety grip 2 in winter. Even when the grip part 2b is touched with the hand, the grip part 2b is maintained at an appropriate temperature, so that the grip part 2b does not feel cold and can be used in a good condition.

As the filler B, a resin having good thermal conductivity can be used. For example, a resin mixed with metal powder or the like can be used in order to improve the thermal conductivity.

Next, FIGS. 5 and 6 show modified examples of the safety grip.

That is, the safety grip 12 shown in FIG.
It is fixedly installed through a hole, and is formed to have a short length in the vertical direction.

In such a safety grip 12, as shown in FIG. heat absorbing part 14b at the lower end of the heat pipe 14.
If the heat pipe 14 is extended and installed on the back side of the bathtub 1, when the bathtub 1 is filled with hot water, the heat pipe 14
The heat absorbing part 14b is heated and the heat dissipating part 14a at the upper end is heated.
Since heat is transferred to the safety grip 12
The grip 12 can be heated well, and the safety grip 12 can be kept at an appropriate temperature in winter or the like.

Incidentally, in order to increase the heat retention effect of the safety grip 12, it is preferable to arrange a large number of fins 15 around the heat radiation part 14a at the upper end of the heat pipe 14.

(Effect of the invention) The safety grip for a bathtub of the present invention incorporates at least the heat radiating part of a heat pipe whose lower part forms a heat absorbing part and whose upper part forms a heat radiating part. The heat absorbing part is located below the hot water level in the bathtub.
The heat of the hot water filling the bathtub is effectively transferred to the safety grip via the heat pipe, and the safety grip is kept at an appropriate temperature, making the safety grip feel cold in winter. It has the effect of improving the function of the safety grip by presenting a good condition of use without causing any damage.
