The door plate 22 is composed of a sound insulation door plate or the like, and the door plate 22 incorporates an opening / closing material 26 for opening and closing the vent 24, and the toilet room 21 is ventilated at a high place (not shown). There is an exhaust port for
As shown in FIG. 7B, when the opening / closing material 26 is raised and the vent 24 is opened, the air in the adjacent chamber 23 is drawn into the toilet room 21 through the vent 24 and exhausted to the outside through the vent. As shown in FIG. 6B, the opening / closing material 26 is lowered and the vent 24 is closed, so that a sound insulation state is formed.

  Then, as shown in FIG. 7 (b), when the closed door plate 22 is opened and closed in a ventilated state where the vent 24 is open, the vent 24 is opened as shown in FIG. 6 (b). When the door plate 22 is opened and closed by closing with the opening / closing material 26, the vent 24 is opened and a ventilation state is formed as shown in FIG. Has been made.

  As a mechanism for realizing this, the following mechanism using the knock mechanism 1 is employed.

  That is, as shown in FIGS. 6 to 8, of the left and right side frames of the door frame, the inner surface of the side frame 28 on the side where the door plate 22 is pivotally attached by the hinge 27 has the hinge 27. A hole 29 is formed by machining at a position away from the rotation center position O, and the cylinder 3 of the knock mechanism 1 is directed in a direction perpendicular to the inner surface of the side frame 28 in the hole 29.

So that the hole 29 is concealed by the collar portion 8c, and the processing depth of the hole 29 may be set to be equal to or greater than the length of the cylinder 3, so that the construction can be easily performed. Has been made.

  Also, on the side surface portion of the door plate 22 on the pivot attachment side, a switch rod 30 as a switch body is directed in a direction orthogonal to the side surface portion, corresponding to the position of the pushing operation body 2 of the knock mechanism body 1. The second spring 31 is provided so as to be able to advance and retreat in this direction and to protrude outward, and has an urging force larger than the urging force of the first spring 9 provided in the knock mechanism 1. It is held in the forward projecting position.

The switch rod 30 uses an opening / closing member 26 that opens and closes the vent 24 as a device that is subjected to switching control of the operating state, and when the switch rod 30 protrudes outward by a transmission mechanism 32 incorporated in the door plate 22. When the opening / closing material 26 is raised and the vent 24 is held open, the switch rod 30 is pushed toward the inner side of the door plate 22 against the urging force of the second spring 31. When retreating, the opening / closing material 26 is lowered to close the vent 24.

  As a result, the door plate 22 is closed, the push-motion moving body 2 of the knock mechanism body 1 is pushed by the switch rod 30 and retreats beyond the retreat prevention position, and the switch rod 30 is held at the advanced position and the vent 24 is opened. When the door plate 22 is opened and closed in the open state, the switch rod 30 is attached to the second spring 31 by preventing the push-motion moving body 2 of the knock mechanism body 1 from retreating at the retraction prevention position. The vent 24 is closed by the opening / closing material 26 against the force and is held at the retracted position. When the door plate 22 is opened and closed from this state, the push-motion moving body 2 of the knock mechanism 1 is moved. By allowing the retraction beyond the retreat prevention position, a series of operations in which the switch rod 30 is advanced by the urging force of the second spring 31 and held in the advanced position and the vent 24 is opened is repeated. Mouth 2 There are adapted to be opened and closed switching control by opening and closing member 26.

  Further, in this embodiment, as shown in FIG. 3B, the tip 30a of the switch rod 30 has a convex spherical shape as a convex arc shape, and the tip 2a of the push-motion moving body 2 of the knock mechanism 1 is It has a concave spherical shape as a concave arc shape, and one of the convex spherical tip portion 30a and the concave spherical tip portion 2a pushes the other to perform the advancing and retreating operation as described above. Yes.

  This is because, in the opening / closing operation of the door plate 22, in the process in which one of the pushing motion body 2 of the knock mechanism 1 and the switch rod 30 pushes the other, their axial directions change relatively. The convex spherical tip surface 30a and the concave spherical tip surface 2a allow the pushing motion body 2 and the switch rod 30 to be pushed in the pushing process. This is to realize a smooth switching control operation of the opening / closing material 26 by making it stable and smooth.

  According to the above-mentioned toilet ventilation sound insulation structure, the door plate 22 of the toilet is properly closed so that the door plate 22 can be opened and entered for the toilet in the ventilation state. When the plate 22 is closed, the open vent 24 is closed and a sound insulation state is formed, and the action sound does not leak outside. After the action is finished, the door plate 22 is opened, and the door plate 22 is opened. When closed, the closed vent 24 is opened and a ventilation state is formed. For example, even when a man urinates, the toilet can be reliably sound-insulated, However, leakage into the adjacent chamber 23 through the vent 24 can be prevented.

  In addition, since such a structure is realized by using the knock mechanism body 1 having the above-described configuration, the knock mechanism body can be easily manufactured with a simple structure, and the door side frame 28 can be manufactured. Can be easily applied, and a smooth switching control operation of the opening / closing member 26 can be realized.

  In addition, a door plate called an inner surface portion of the side frame 28 on the side where the door plate 22 of the left and right side frames of the door frame is pivotally attached by a hinge 27 and a side surface portion of the door plate 22 on the pivot attachment side. Since the knock mechanism body 1 and the switch rod 30 are incorporated focusing on the portion that undergoes relative displacement in accordance with the opening / closing operation of the door 22, the switching control of the opening / closing member 26 that is linked to the opening / closing operation of the door plate 22 is realized. In addition, the knock mechanism 1 and the switch rod 30 can be concealed between the surface portions in a state where the door plate 22 is closed, so that the appearance of the joinery is improved. it can.
