[Problems to be solved by the present invention] However, in a ventilator in which a ventilation port provided on the outdoor wall of the lower frame is opened and closed by a slide plate, the cut surface of the vented hole is the outdoor side when undressing. It is not allowed to be exposed to the room etc. and damage the appearance, but due to the hot air from the bottom, the condensation water generated around the ventilation opening and the glass surface on the outside of the room flows down or the impact when opening and closing the folding door is directly exposed There is a drawback that it scatters and deteriorates flooring materials such as a dressing room.

The present invention was devised to eliminate the above-mentioned drawbacks, and is intended to ventilate a room by opening and closing the ventilation port, but the cutting surface of the vent hole with holes is an outdoor room such as a dressing room. It is an object of the present invention to provide a ventilator for a folding door, which can have a good appearance without being exposed to the outside, and in which condensed water does not directly flow to the outside of the room or splash to the dressing room side.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the technical means taken by the present invention is as follows:
An opening that is continuous in the left-right direction is formed so as to have a rising portion that extends upward from the bottom surface of the lower frame, and an inclined water droplet guide surface is provided at the upper end side of the opening toward the bottom surface of the lower frame. On the other hand, a slide with a plurality of ventilation holes formed at a predetermined interval on the bottom of the lower frame to form a ventilation circulation path communicating with the inside and outside of the bathroom, and a ventilation hole corresponding to the ventilation hole formed on the bottom surface. A plate is slidably provided, and a desired portion of the bathroom-side end edge of the slide plate is extended upward along the lower-frame fitting surface to form a mounting seat, and the bathroom-side lower frame facing the mounting seat is formed. A guide groove having a predetermined length in the left-right direction is formed on the found surface, and a ventilation knob for slidingly adjusting the slide plate between the ventilation position and the closed position is provided on the mounting seat through the guide groove. It is what

[Advantage of the Invention] Therefore, according to the present invention, by sliding the slide plate, the ventilation opening formed in the bottom surface of the lower frame is opened and closed to adjust the ventilation circulation path communicating with the inside and outside of the room, and the inside of the room can be freely adjusted. Can be ventilated.

And, since the outdoor surface of the lower frame is provided with only a continuous opening in the left-right direction that forms a rising part that extends upward from the bottom surface of the lower frame, the cutting surface at the time of drilling is the dressing room. It is not exposed to the like, and the appearance can be improved. In addition, the slide plate provided on the bottom of the lower frame slides to open and close the ventilation opening, and ventilation is interrupted at the position of the bottom, so when not ventilating, hot air from the bathroom, etc. will enter the lower frame and condense water. It is possible to reduce the occurrence of water drops as much as possible.Only the left and right openings are provided on the outside of the lower frame, and the inclined water droplet guide surface extends toward the bottom of the lower frame at the upper end side. Since it is provided, it is possible to prevent the dew condensation water attached to the outdoor glass surface from directly flowing down to the outdoor side and being scattered to the undressing room on the outdoor side when the folding door is opened and closed. In addition, since the rising surface that extends upward from the bottom surface of the lower frame is formed on the bathroom outside facing surface of the lower frame that is provided with an opening, water droplets will not be generated even when the slide plate is in the closed position. It does not flow into the changing room.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Reference numeral 1 denotes a folding door installed at an entrance / exit of a bathroom, etc., which is constituted by door bodies 2 and 3 which are rotatably connected to each other. It is designed to open and close. 6 is a roller that rolls on the upper guide rail 4, and 7 is a sliding member that engages with the lower guide rail 5.

Reference numeral 8 denotes a lower frame that forms the lower end of the folding door 1. The outdoor frame surface 9 of the lower frame 8 is integrally formed in a horizontally long shape so as to have a rising portion 9a extending above the lower frame bottom surface 11. The formed opening 10 in the left-right direction is provided toward the dressing room and the like.
An inclined water droplet guide surface 12 extends toward the lower frame bottom surface 11 on the upper end side of the. On the other hand, on the bottom surface 11 of the lower frame 8 facing the bathroom or the like, a plurality of ventilation openings 13, 13 ... Are continuously formed at predetermined intervals, and the folding door 1 is closed and undressed with the bathroom side. A ventilation distribution path A communicating with the room side is formed.

14 is a slide plate disposed on the bottom surface 11 of the lower frame 8,
Ventilation holes 15, 15 ... Corresponding to the ventilation holes 13, 13 ... Are formed in the slide plate 14, and rising portions 14a, 14b standing on both sides of the sliding plate 14 are raised portions 9a on the undressing room side. It is guided between the facing surface 16 on the bathroom side and the facing surface 16 on the bathroom side and is slidable left and right. The rising portion 14a on the bathroom side is further bent and extended upward, and a mounting seat 19 having a mounting hole 18 for the ventilation knob 17 is integrally formed at the upper end portion thereof.

The ventilation knob 17 has a knob body 20 as shown in FIG.
Locking pawls 21 and 21 are formed on the back side of the projection so as to face each other, and the locking pawls 21 and 21 are inserted into the guide groove 22 provided on the mounting surface 16 from the bathroom side and press-fitted into the mounting hole 18. The ventilation knob 17 is attached and fixed to the attachment seat 19 by being locked. When the ventilation knob 17 is moved along the guide groove 22, the sliding ventilation hole 15 of the slide plate 14 overlaps with the ventilation hole 13 of the bottom surface 11, and the ventilation hole 15 of the ventilation hole 13 is overlapped. The ventilator can be freely opened and closed in the closed state in the middle.

In the above structure, when the bathroom is ventilated with the folding door 1 closed, the slide plate 14 having the vent hole 15 slides on the bottom surface 11 only by operating the ventilation knob 17 from the bathroom side. Since the ventilation port 13 can be opened and closed to adjust the ventilation flow path A that connects the bathroom side and the dressing room side, the bathroom can always be in a comfortable ventilation state.

Further, since only the opening 10 continuous in the left-right direction is formed on the lower frame facing surface 9 on the outside of the room, the cutting surface by the hole processing is the same as the conventional one having a plurality of ventilation openings. It is not exposed to the side and the appearance can be improved. On the other hand, when the bathroom is not ventilated, the slide plate 14 with the ventilation port 13 closed shuts off water vapor or the like from the bathroom at the position of the bottom surface 11, so that the water vapor or the like enters the lower frame 8 to generate dew condensation water. The opening 10 on the undressing room side is integrally formed in the left-right direction, and an inclined water droplet guide surface 12 extends toward the lower frame bottom surface 11 at the upper end side thereof. Since the condensed water attached to the outdoor glass surface directly flows down to the outdoor side, and even when the folding door 1 is opened or closed, water droplets do not splash from the opening 10 to the changing room and enter the flooring etc. , It flows down along the water drop guide surface 12 and is discharged to the bathroom side as it is.

Further, the ventilation knob 17 having the locking claws 21, 21 can be securely mounted by simply press-fitting and locking it in the mounting hole 18 without using a tightening tool such as a special screw, etc. It is possible to simplify the assembly work of the device.

And a slanted water drop guide surface extends toward the bottom surface of the lower frame at the upper end of the opening, while a plurality of ventilation openings are formed at predetermined intervals on the bottom surface of the lower frame. A slide plate with a ventilation hole communicating with the inside and outside of the bathroom is formed slidably on the bottom surface, and a ventilation hole corresponding to the ventilation hole is provided on the bottom surface of the slide plate. A slide seat is formed by extending upward along the siding face to form a mounting seat, and a lower groove siding face on the bathroom side facing the mounting seat is formed with a guide groove having a predetermined length in the left-right direction. A ventilation knob for slidingly adjusting the ventilation position and the closing position is provided on the mounting seat through the guide groove. Therefore, by simply sliding the slide plate, it is possible to freely open and close the ventilation circulation path that communicates with the inside and outside of the room to create the optimal ventilation state in the bathroom etc. Since the opening of is open continuously in the left-right direction and the rising part that extends upward from the bottom of the lower frame is formed, the cut surface due to hole processing etc. is not exposed in the dressing room etc. , The appearance can be good. Moreover, since the slide plate that slides the ventilation port provided on the bottom of the lower frame opens and closes, when not ventilating, water vapor etc. is blocked at the bottom position to minimize the formation of condensed water in the lower frame. Moreover, only the left and right openings are provided on the outdoor side of the lower frame, and an inclined water drop guide surface that allows water drops to flow toward the bottom surface of the lower frame is provided on the upper end side. Condensation water adhering to the glass surface of the outdoor side does not flow directly to the outdoor side or splash to the undressing room on the outdoor side when the folding door is opened and closed. It is possible to prevent the deterioration of the product. Also, since the ventilation knob is located on the bathroom side facing surface of the lower frame of the folding door, it is easy to operate, and since the ventilation knob is provided on the slide plate via the guide groove, The sliding position can be easily adjusted by adjusting the left and right lengths to a predetermined dimension to regulate the left and right sliding of the slide plate.
