Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sauna.

[Conventional technology]

Recently, a home sauna as shown in FIG. 3 has been used. In this home sauna S, heating means (electric stove or the like) is provided in the bathroom 21, and a door 22 is provided at the entrance of the bathroom 21. The user opens and closes the door 22 to enter and exit.

The door 22 is an auto-close type. The hinges 23, 23 to which the door 22 is attached are hinges that act in the closing direction. The auto-close type is used because if it is not, the heat in the bathroom will escape to the outside while the door 22 is inadvertently left open.

[Problems to be solved by the device]

However, if the hinges 23, 23 that act in the closing direction are used, the speed at the time of closing becomes too fast and the usability is poor.

If one of the hinges 23 is changed to a hinge that acts in the opening direction, the door will close at an appropriate speed.
Is always in a state of unbalanced force applied up and down,
For this reason, the door 22 is twisted, and a gap is particularly likely to be formed on the side provided with the hinge that acts in the opening direction.

In view of the above circumstances, it is an object of the present invention to provide a sauna that has an appropriate speed at the time of closing the door and does not cause a twist or a gap.

[Means for Solving the Problems]

In order to solve the above problems, in the sauna of the present invention, a door is provided at the entrance / exit of the bathroom, and spring hinges that act on the elastic restoring force in the closing direction are attached to the upper and lower positions of the door, respectively, and the middle of the door is attached. A spring hinge is attached to the position so as to exert an elastic restoring force in the opening direction.

[Action]

In this sauna, the hinges acting in the closing direction are provided at the upper and lower positions, and the hinges acting in the opening direction are provided between them, so that the force applied to the door is balanced and the door is not distorted.

If there is a hinge that acts in the opening direction at the top and bottom of the door, there is nothing to stop the door in the opening direction, and the edges tend to warp, so there is a gap easily, but the hinge is in the middle position of the door, The upper and lower positions are hinges that act in the closing direction, so it is difficult to leave a gap.

The combined use of the hinge acting in the closing direction and the hinge acting in the opening direction allows the door to automatically close at an appropriate speed.

Moreover, since both the hinge acting in the opening direction and the hinge acting in the closing direction are spring hinges that act on the elastic restoring force, the basic structure is exactly the same, and the springs that change only the acting direction of the elastic restoring force. You can use hinges. Because of the structure of the spring hinge, it is easy to change the direction of action of the elastic restoring force. Therefore, even if two types of hinges having different directions of action are used, manufacturing is easy and the cost is low.

Furthermore, when the door is closed, the action force of the two spring hinges in the closing direction in the weakest state and the action force of the one spring hinge in the opening direction in the strongest state are relatively different from each other. Only a weak closing force is acting. Therefore, when opening the closed door, the door begins to open with a slight force.

When the door is fully open, the acting force of the two spring hinges in the closing direction is the maximum, and the acting force of the one spring hinge in the opening direction is the minimum, so that a large force acts on the door in the closing direction. , When the door is released, it immediately starts moving in the closing direction. However, when the door approaches the closed position, the force acting on the door in the closing direction sharply decreases due to the above-described action, so that near the closed position, the door gradually decreases the operation speed, and finally, You will exercise very slowly. That is,
The movement of the door or the opening of the door from the fully opened state is quick, and near the closed position, it is extremely gentle.

〔Example〕

Hereinafter, the sauna according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

1 (a) to 1 (c) show an embodiment of the sauna of the present invention.

The sauna S has an electric stove 2 as a heating means in the bathroom 1.
And an electric light (not shown) as a lighting means, and an automatic closing type door 3 at the entrance / exit. The door 3 is attached to the doorway by an upper hinge 4, a lower hinge 5 and a middle hinge 6. The door 3 is attached so that it can be opened and closed in an open manner.

The upper hinge 4 and the lower hinge 5 are hinges acting in the closing direction, and the middle hinge 6 is a hinge acting in the opening direction. Therefore, it has the above-mentioned utility. These hinges 4, 5, 6
Uses a spring hinge that utilizes elastic restoring force.

The spring hinge has a structure as shown in FIG. 2, for example.

The spring hinge H includes a tubular shaft portion 11. Coaxial section 11
Has two cylindrical portions 12 and 13. One of the cylinders is the rotating side, and the other cylinder is the fixed side.
Blades 15 and 16 are provided on the cylindrical portions 12 and 13, respectively. The holes 15a and 16a are for fixing.
Both cylindrical portions 12 and 13 are rotatably passed through a shaft 17. Both ends of the shaft 17 have insertion holes 12 respectively.
It is retained by the cylinder bases 12a and 13a when it comes out of b and 13b. A bearing mechanism 14 is provided at the abutting portion of the cylindrical portions 12 and 13. The barrel and blades are made of rust-resistant material such as aluminum and stainless steel.

On the other hand, the metal spring body 1 is provided in the inner space 11a of the tubular shaft portion 11.
8 are provided. The spring body 18 has ends 18a, 1
8b are fitted in the holes 12c and 13c, respectively.
Therefore, one end 18a is connected to the cylinder portion 12 and the other end 18b is connected to the cylinder portion 13, and the elastic restoring force when the spring body 18 is twisted exerts an action on the hinge H in the closing direction and the opening direction. To be made. When the door 18 is closed and the spring body 18 still has a twist, the door 18 can be opened or closed in the closed state.

This invention is not limited to the above embodiment. As the hinge, a hinge having a structure other than those exemplified above may be used.
The structure of the sauna is not limited to that illustrated.

[Effect of device]

In the sauna of this invention, the hinges acting in the closing direction are arranged at the upper and lower positions of the door, and the hinges acting in the opening direction are arranged at the middle position of the door, so that the door automatically moves at an appropriate speed. Closed, and the door is not twisted and there is no gap between the door and the doorway.

Moreover, as the above two types of hinges,
Since the spring hinge that applies the elastic restoring force is used, it is easy to change the acting direction of the elastic restoring force between the opening direction and the closing direction while keeping the basic structure the same, for example, the spring hinge and the oil damper. It is much easier to manufacture and cheaper than a structure with attached hinges.

In addition, it is quick to start closing from the fully open state,
Near the closed position, it will gradually close very gently. In addition, you need only apply a small amount of force to start opening the door. That is, at any stage of the closing start operation from the fully opened state, the final closing operation near the closed position, and the opening start operation from the closed position, an appropriate force is applied according to each stage, and the door is closed. Can be operated properly, which is extremely convenient for the sauna user.
