Description

  The present invention relates to a bathroom door installed at the entrance / exit of a bathroom unit room, and more particularly, to air circulation with the exterior of a bathroom at a face material holding portion of a two-fold door.

  Conventionally, a two-fold door is known as a door of a bathroom unit room. This type of folding door opens and closes when the door body slides with respect to the rails arranged on the door frame, and the door body is folded or unfolded around the central hinge. It has a structure.

  Such a double-folded door has an advantage that when the door is opened and closed, the protrusion length to the bathroom side is almost half compared to the swing door, so that the door does not get in the bathroom even when opened. In addition, the body frame and face material are made of lightweight materials, and the latch is released by a pushing operation (or pulling operation) with a slight force. There is also an advantage.

The following patent document discloses a structural example of a double-folded door of a bathroom unit room.
Japanese Patent Laid-Open No. 9-324584

  In recent years, however, the latching force of the double-folded door is weak as described above, which causes the phenomenon that the door opens naturally due to the airflow caused by the ventilation operation of the ventilation dryer installed in the bathroom and the atmospheric pressure difference between the inside and outside of the room. is doing.

  To solve this problem, methods such as increasing the latching force or increasing the louver area at the bottom of the door to improve the air flow to the outside are considered. If it is, opening and closing requires force, it becomes difficult to operate especially for elderly people, and if the louver area is increased, there is a problem that the waterproof effect is lowered.

  On the other hand, a method is also conceivable in which a gap is provided in the face material holding portion of the door or in the vicinity thereof to circulate air to the outside. In particular, some conventional two-fold doors have a locking member called a grating channel interposed between the ridge and the face material in order to hold and fix the door face material. A method of providing a gap around the periphery is also conceivable, but the U-shaped locking member and the locking member for holding one side of the face material have the purpose of improving airtightness and watertightness in the first place. It was not a structure capable of providing a large gap.

  The present invention has been proposed in view of such circumstances, and an object thereof is to provide a bathroom door having a face material holding structure that is not easily opened naturally by an air flow in the bathroom. is there.

  To achieve the above object, the bathroom door according to claim 1 forms a hollow between the dressing room side vertical wall portion and the bathroom side vertical wall portion, and holds the face material by the both side vertical wall portions. It is a bathroom door having a structure in which the face material holding member made to be attached to a bag, and the face material holding member has an opening formed in the dressing room side vertical wall portion and the bathroom side vertical wall portion, The air is circulated from the dressing room side to the bathroom side through these openings, and a check valve for preventing air flow opposite to the above is provided in the air flow passage.

  According to a second aspect of the present invention, the face material holding member is further formed with a water drain hole communicating from the hollow portion to the outside.

  In the third aspect, the check valve is provided in the opening of the bathroom side vertical wall portion, and the opening is normally closed and opened to the bathroom side when the wind pressure of the air flow from the dressing room side to the bathroom side acts. It is characterized by comprising a lid that can be used.

  According to a fourth aspect of the present invention, the check valve is made of an elastic sheet material attached to one side of the opening on the bathroom surface side.

  According to the bathroom door of Claims 1-4, the face material holding member for attaching to a bag and holding a face material was formed in the dressing room side vertical wall part and the bathroom side vertical wall part. Since it has an air flow passage that circulates air from the dressing room side to the bathroom side through the opening, and the flow passage is provided with a check valve for preventing air flow opposite to the above, the exterior of the bathroom The air can be effectively taken in, and the outflow of air and moisture can be prevented.

  Therefore, even when the ventilation dryer is operated, since the outside air enters, the difference in atmospheric pressure between the bathroom and the dressing room is reduced, and the door does not open due to airflow or wind pressure.

  Further, in a state where the ventilation dryer is not operated, the check valve structure can prevent the inflow of water into the face material holding member, and air does not flow out to the outside, so that the drying and heating effects are not deteriorated.

  In particular, if this face material holding member is used for an upper gutter that is not normally provided with a louver, the above-described effects can be effectively exhibited for a ventilation dryer installed on the ceiling.

  According to the second aspect, since the drain hole is formed in the face material holding member, the moisture that has entered the hollow portion of the face material holding member can be effectively discharged.

  In claim 3, the check valve is composed of an opening lid provided on the bathroom side vertical wall portion, and since this lid body is normally closed, it is effective for preventing water from entering the hollow portion, It is also very easy to install.

  In claim 4, since the check valve is made of an elastic sheet material attached to one side of the opening on the bathroom surface side, the check valve can be configured simply using its elastic deformation and restoring elasticity. And can be attached more easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 3 is a front view of the bathroom door of the present invention as viewed from the bathroom side.

  A door frame 20 and a two-fold door body 10 are disposed in a door opening (not shown) of a bathroom unit room (not shown). The door frame 20 includes door upper and lower frames 21 and 21 and door left and right frames 22 and 22, and is connected and fixed to a building floor (not shown), a building wall (not shown), and the like.

  On the other hand, the door frame portion which is the double-folded door main body 10 is composed of an upper rod 1, a lower rod 6, a vertical rod 4, and an intermediate beam 5 made of aluminum, an aluminum alloy, or a resin. Then, a semi-transparent resin face material 3 is supported and fixed to the surface area surrounded by these ridges 1, 4 and 6 via a face material holding member 2 or other face material holding member described later. Is done. A gallery 8 for intake or exhaust is attached below the lower rod 6. Reference numeral 9 denotes a door opening operation puller.

  In addition, a hinge portion 7 is provided inside the central vertical shaft 4 so that it can be bent right and left from the center of the door body 10.

  FIG. 1 is a longitudinal sectional view of a main part of a bathroom door according to the present invention, in which (a) is a sectional view taken along the line AA in FIG. 3, and (b) is an enlarged view of a portion X in (a). FIG. 2 is a perspective view showing the appearance of the face material holding member 2.

  A rail body 21a is formed on the door upper frame 21 along the longitudinal direction, and the door pulleys 10a formed at the upper and lower ends of the left and right ends of the two-fold door body 10 can slide along the rail body 21a. (The rail structure diagram in the lower part is omitted). One of the left and right ends is hinged (not shown) connected to either the door left or the right frame 22, 22 or in the vicinity thereof, and the other end is installed so that it can be slid open.

  In addition, a latch portion 10b configured to include a spring (not shown) for stopping when the door is closed is formed at the upper center of the double-folded door main body 10, and the door main body 10 is closed. The latch portion 10b is sometimes locked to the rail body 21a, and the lock is released when the door body 10 is opened. The latch structure may be a magnetized structure using permanent magnets.

  That is, by pulling the handle 9 on the bathroom B side toward the bathroom B side or pressing the vicinity of the hinge portion 7 from the dressing room A side, the latch is released, and the door portion 10a moves the rail body 21a, and the hinge portion 7 , The door body 10 is folded and the door opening is opened.

  As described above, the face material 3 is held and fixed to the surface area surrounded by the flanges 1, 4, and 6 via the face material holding member 2 and the like. It is fixed via the holding member 2.

  An opening 1a for inserting the face material holding member 2 is formed at the lower end of the upper collar 1, and it is bent from the dressing room side vertical wall 1A and the bathroom side vertical wall 1B to the lower end opening 1a. Inwardly hooked locking portions 1b and 1b for locking the face material holding member 2 are formed.

  On the other hand, the face material holding member 2 is a hollow material made of aluminum, an aluminum alloy, a resin, etc., and along the longitudinal direction, the base material 2h constituting the bottom part has a face material insertion port 2e and a lower part of the inner wall. A pair of elastically deformable face material deterring parts 2g and 2g arranged opposite to each other with a space slightly smaller than the thickness of the face material 3 are formed on the upper side of the vertical wall parts on both sides, and are outwardly hooked main body locking parts 2f along the longitudinal direction. 2f is formed, and the width between the outer edges of the locking portions 2f and 2f is slightly larger than the width between the inner edges of the locking portions 1b and 1b.

  When the face material holding member 2 is attached to the opening 1 a of the upper collar 1, the main body locking portions 2 f and 2 f of the face material holding member 2 are pressed and elastically deformed by the locking portions 1 b and 1 b of the upper collar 1. When the main body locking portions 2f and 2f pass through and enter the upper collar 1, the locking portions 1b and 1b and the main body locking portions 2f and 2f are engaged with each other, and the face material holding member 2 is mounted and held.

  Further, when the face material 3 is attached to the face material holding member 2, the face material 3 is inserted from the face material insertion port 2e, and the face material deterring portions 2g and 2g are inserted into the hollow portion while being elastically deformed. . When the face material 3 is inserted to a predetermined position, both side surfaces of the face material are pressed by the elastic force of the face material deterring portions 2g and 2g and are held without rattling.

  As shown in FIG. 1, the face material holding member 2 is provided with openings 2a and 2b in the dressing room side vertical wall portion 2A and the bathroom side vertical wall portion 2B. As shown in FIG. 2, a plurality of the openings 2 a and 2 b are provided along the longitudinal direction of the face material holding member 2, and the positional relationship between the openings 2 a and 2 b is for water stoppage on the dressing room A side. It is desirable to open the openings 2a and 2b so that they do not face each other, that is, shifted vertically and horizontally as shown in the figure. Since FIG. 2 is a perspective view as seen from the bathroom B side, only one opening 2a is provided in the dressing room side vertical wall 2A. Further, in the vertical relationship, it is desirable that the opening 2b on the bathroom B side is located at a lower position than the opening 2a on the dressing room A side.

  In addition, check valves 2c1 and 2c2 that prevent air from flowing from the bathroom B side to the dressing room A side are provided at appropriate positions in the air flow passage C formed by the openings 2a and 2b. That is, the check valve 2c1 provided in the opening 2b of the bathroom-side vertical wall 2B is attached to the lower piece side of the opening 2b and is configured as a lid that closes the opening 2b when there is no air flow (FIG. 2). On the other hand, the check valve 2c2 provided in the hollow portion is attached to the inner wall of the bathroom side vertical wall portion 2B of the face material holding member 2, and air flows in the direction of the arrow in FIG. In order to sometimes open and prevent the backflow, it is always attached so as to close the space formed between the inner wall and the face material 3. Note that only one of the check valves 2c1 and 2c2 may be installed. Moreover, an installation location is not limited to said location.

  The check valves 2c1 and 2c2 are preferably made of an elastic sheet material such as lightweight rubber, but are not limited thereto. If an elastic sheet material is used, a check valve can be easily configured using its elastic deformation and restoring elasticity.

  According to the above configuration, when a pressure difference occurs indoors or outdoors such as when an air flow is generated by operating a ventilation dryer (not shown) in the bathroom B, the bathroom from the dressing room A side is used. The wind pressure due to the air flow to the B side acts, so the check valve 2c2 in the hollow part opens, and the upper side of the check valve 2c1 provided in the opening 2b of the bathroom side vertical wall part 2b falls to the bathroom B side. The opening 2b is opened, and air flows from the dressing room A side to the bathroom B side through the air flow path C from the opening 2a to the opening 2b.

  On the contrary, when the ventilation dryer does not operate and the air flow does not occur, the opening 2b is closed by the check valve 2c1 attached to the opening 2b, and the air flow passage C is kept closed. Even if the opening 2b is opened and air flows in, the air flow passage C is blocked by the check valve 2c2.

  That is, such an air flow passage C with a check valve allows only air flow from the dressing room A side to the bathroom B side, and prevents the reverse air flow. As a result, even if the ventilation dryer is operated in the bathroom B, the two-fold door 10 can be prevented from being naturally opened by the wind pressure. Further, the check valves 2c1 and 2c2 can prevent water from flowing into the face material holding member 2, and since air does not flow out to the dressing room A side, the drying and heating effects are not reduced.

  Further, the face material holding member 2 is formed with a plurality of drain holes 2d, 2d,... In the right place near the upper part of the base part 2h on the bathroom B side (see FIG. 2). reference).

  Thus, since the drain hole 2d is provided, even if water enters from the openings 2a and 2b, it can be discharged to the bathroom B side.

  In the above embodiment, the example of the face material holding member 2 disposed on the upper rod 1 is shown. However, the air with check valve as described above is attached to the face material holding member mounted on the lower rod 6 and the vertical rod 4. A flow passage may be provided. For example, you may provide this face material holding member 2 in the lower part of a door as a substitute of a louver.

  Since the ventilation dryer is often installed on the ceiling in the bathroom B, and the wind pressure often acts on the upper part of the door, the face material holding member 2 for the upper lid 1 is provided with a check valve as described above. It is more effective to provide an air flow passage.

  Moreover, although the said Example has shown the thing of a two-fold door, said face material holding member is employ | adopted for the bathroom door of another system, and it replaces or adds to a louver for normal ventilation. It can also be used.

It is a principal part longitudinal cross-sectional view of the bathroom door of this invention, (a) is sectional drawing of the AA line of FIG. 3, (b) is an enlarged view of the X section of (a). It is a perspective view of a face material holding member. It is the front view seen from the bathroom side of the bathroom door of this invention.
