Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing structure for a bathroom folding door, and more particularly to an opening / closing structure capable of reducing the frictional resistance between a folding door shoji and a waterproof member when the folding door is opened and closed.

[0002]

2. Description of the Related Art In general houses, folding doors are widely used at present as being suitable for entrance doors of bathrooms because of their small amount of projection in the expected direction when opened compared to other opening and closing doors. I have. This bathroom folding door basically includes a pair of folding door sashes that frame upper and lower frames and left and right vertical frames in a frame body that frames upper and lower frames and left and right vertical frames.

Here, in the bathroom folding door, it is necessary to take sufficient waterproofing measures so that water from the bathroom does not enter the dressing room through the gap between the folding door shoji and the frame. Conventionally used as such a waterproofing measure, a bead material made of a soft resin is attached along the four circumferences of the frame, and when the folding door is closed, the frame of the folding door shoji is beaded. It is to be pressed against the material.

[0004]

However, the conventional open / close structure of a bathroom folding door has the following problems. First, when opening and closing the Orito Shoji, the frame of the Shoji slidingly contacts the bead material, and there is a problem that the sliding of the Shoji cannot be performed smoothly due to the resistance. That is, with the opening and closing of the folding door shoji, the vertical frame of the fixed side shoji turns and slides on the bead material, and the frame of the movable side shoji moves along the frame while rotating and moves along the bead material. Sliding contact occurred before and after the movement, which was a large load for opening and closing. Further, the sliding contact between the bead material and the frame body causes the bead material to be worn and deformed, and the watertightness when the folding door is closed tends to become insufficient in a short period of time. In addition, the sliding contact between the bead material and the frame may generate a noise, which may discomfort the user.

Further, in order to avoid the load at the time of opening and closing as described above, wear of the bead material, and noise, a bathroom folding door using a brush-like mohair material instead of the bead material has also been proposed. Since the material is less watertight than the bead material and is expensive, it is not preferable, and there has been a demand for a bathroom folding door which can solve the above-mentioned problem while using the bead material.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a bathroom folding door opening / closing structure capable of reducing frictional resistance between a waterproof member such as a bead material and a frame when opening / closing a folding door shoji. It is intended to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1 and 2 are a vertical sectional view and a horizontal sectional view of a bathroom folding door to which an embodiment of the present invention is applied. FIG. 3 is a cross-sectional view of the folding door shoji in an open state, and FIG. 4 is an exploded perspective view of the folding door shoji. In each of these figures, the bathroom folding door has a pair of folding door shojis 10 and 11 housed in a frame material composed of upper and lower frames 1 and 2 and left and right vertical frames 3 and 3 installed at an entrance opening 40 of the bathroom. Things.

A pair of folding door screens 10 and 11 are connected to a connecting frame 12.
Are rotatably connected to each other. One of the left and right ends of the folding door shojis 10 and 11 is rotatably supported by the upper and lower frames 1 and 2 at a pivot point P (hereinafter, this side is referred to as a fixed side shoji), and the other end is an upper and lower frame. The upper and lower frames 1 and 2 are freely rotatable while being guided by the upper and lower frames 1 and 2 (hereinafter, this side is referred to as a movable side shoji). As a result, the two Orito Shojis 10, 11
It is folded into two around the connecting frame 12, and the entrance opening 4
0 can be released. The operation of opening the folding door shoji is performed by pulling the handle 6 attached to the movable shoji 11 from the bathroom 41 side and pushing the movable shoji 11 itself from the undressing room 42 side.

As can be seen particularly clearly from the exploded view of the Orito shoji shown in FIG. 4, the fixed side shoji 10 and the movable side shoji 11 are respectively separated from the upper and lower stiles 13 and 14, the abutting vertical stile 15 and the outer vertical stile 16 respectively. An acrylic panel material 17 is placed in a frame material. The panel member 17 has its peripheral end portion formed by vertically and vertically and vertically and horizontally framed frames 13, 14, 15 and 1.
6 is fixed by being housed together with a bead material 19 in a panel mounting groove 18 formed in 6. The attachment of the panel member 17 to the frame member is performed in the following procedure. That is, the bead member 19 is slid from the end into the panel mounting groove 18 of each of the upper and lower frames and the left and right vertical frames 13, 14, 15, and 16 to be inserted. Upper frame 13, vertical frame 15, lower frame 1
4 and the vertical frame 16 are connected in an L-shape, and a panel material 17 is pressed into one of the panel mounting grooves 18. Next, the panel mounting groove 18 of the other frame is connected to the panel material 17.
And press-fit into the remaining sides to connect the two L-shaped frames to complete the installation. According to such a structure, mounting of the bead material is easy, and the design is improved because the bead material is not exposed. In conventional bathroom folding doors, bead materials were attached after mounting panel materials on the frame, or Grechan was wound on the panel and then fixed to the frame, but these methods required skills and lacked designability. In the latter method, a wide panel mounting groove is required, so that these disadvantages are improved.

As shown in FIG. 1, hinge members (hereinafter, upper hinge 30 and lower hinge 35) are attached to the outside of the movable side shoji 11, ie, above and below the vertical frame 16 near the vertical frame. Have been. The upper hinge 30 and the lower hinge 35 rotatably and slidably support the movable side shoji 11 with respect to the frame material. Grooves for loosely engaging with guide rails 1a, 2a formed on the upper and lower frames 1, 2, respectively, on the rotation shafts 31, 36 of the upper hinge 30 and the lower hinge 35 rotatably supported on the movable side shoji 11. 31a, 36a
Are formed. The rotating shafts 31 and 36 are movable side shoji 1
This allows the shoji to move along the frame while allowing one rotation. Although not shown in the drawing, the vertical hinge 16 outside the fixed side shoji 10 is also provided with an upper hinge and a lower hinge. The basic structure of the upper hinge and the lower hinge on the outer side of the vertical frame 16 of the fixed-side sash 10 is the same as that of the upper hinge 30 and the lower hinge 35 described above. 2 is fixed at point P in FIG. Therefore, when the fixed-side sash (shoji) 10 is opened and closed, only rotation by the rotation shaft is permitted. The specific configuration of each hinge member will be described later.

On the side of the undressing room 42 side of the upper and lower frames 1 and 2 and the left and right vertical frames 3 and 3, contact pieces 4 rising inward are provided.
Are formed so as to be continuous on four rounds. And the bathroom side surface of the contact piece 4, that is, the folding door shoji 1 in the closed state.
A tight member 5 as a waterproof member is attached to a surface adjacent to 0 and 11. In a state in which the fixed-side sash 10 and the movable-side sash 11 are closed, the side walls of these sashes, that is, the upper and lower frames 13 and 14 and the outer vertical frame 16
It is pressed against the tight material 5. This prevents water from the bathroom from entering the undressing room. In the present embodiment, the tight material 5 uses a bead material,
The same bead material 19 used in Orito Shoji can be used. As shown in FIGS. 1 and 4, latches 20 are provided on the upper and lower portions of the connecting frame 12. The upper latch 20 is embedded in the connecting frame 12 as shown in FIG. 4, and when the folding door is closed, it resiliently engages with the guide rail 1a shown in FIG. 1, while the lower latch 20 is As shown in FIGS. 1 and 4, it is attached to the side of the connecting frame 12 on the undressing room side, and when the folding door is closed, it resiliently engages with the contact piece 4 of the lower frame 2 shown in FIG. The pressure contact of the folding door to the tight material 5 is maintained.

FIG. 5 is a simplified and enlarged view of the fixed side sash 10 attached to the frame material, that is, the vertical frame 16 side. It should be noted that the vertical frame 16 side of the movable side shoji 11 has the same configuration. As shown in the figure, the outer surface of the vertical frame 16 facing the vertical frame 3 is formed in a semicircular cross section. In the figure, the center point of the semicircle on the outer surface is shown as a point O. The tight material 5 attached to the frame material, as shown in FIG.
6 and the upper and lower frames 13 and 14.

In the present invention, the fixed-side sash (shoji) 10 is configured to rotate about a fulcrum P that is shifted from the point O. Here, the fulcrum P is located closer to the vertical frame 3 than the point O and away from the tight material 5 (direction closer to the bathroom 41) when the fixed side sash 10 is closed in FIG. I have. As is clear from the figure, the point on the semicircle farthest from the fulcrum P, that is, the point on the outer surface of the vertical frame 16 is the point Q at which the tight material 5 contacts at the time of the figure, and All other points in the shape are
It is located near. Therefore, when the Orito shoji is opened and the vertical frame 16 of the fixed side shoji 10 rotates about the fulcrum P,
A region A of the vertical frame 16 facing the tight material 5 with the rotation.
Passes closer to the bathroom 41 than the position of the tight material 5.
Therefore, as the folding door shoji is opened, the pressing force of the vertical frame 16 against the tight material 5 decreases (it becomes zero when the folding door is completely separated from the tight material 5), and the opening and closing of the folding door becomes smooth.

With respect to the pivot point, the movable side shoji 11 has the same configuration as described above. In the movable side shoji 11, the pivot point moves along the frame member as it is opened and closed, but the positional relationship between the tight member 5 and the vertical frame 16 is the same as that described above. Therefore, the side surface of the vertical frame 16 gradually moves away from the tight material 5 during the rotation, and the resistance due to the rubbing with the tight material 5 during the rotation becomes small.

FIGS. 6 to 9 show the vertical frame 16 of the movable shoji 11.
FIG. 4 is a view showing an upper hinge attached to the, and shows a plan view, a front view, a side view, and a longitudinal sectional view, respectively. In each of these drawings, the upper hinge 30 includes a housing 32 fitted to the upper end of the vertical frame 16 and a rotating shaft 31. As shown in FIG. 9, the lower part of the rotating shaft 31 is rotatably housed in a circular hole 32 a of the housing 32, and the upper part protrudes from the upper part of the vertical frame 16. A groove 31a is cut at the upper end of the rotating shaft 31, and loosely engages with the guide rail 1a of the upper frame. A coil spring 33 is provided at a lower portion of the rotating shaft 31, and when the rotating shaft 31 is pressed from above, the upper portion thereof becomes a circular hole 3.
It retreats into 2a. This facilitates the attachment of the movable side shoji 11 to the guide rail 1a. At the upper end of the rotating shaft 31, an engaging claw 31b for the housing 32 side is formed in order to prevent it from coming off.

The housing 32 has a semicircular cross section substantially corresponding to the outer surface of the vertical frame 16, and is fitted into the vertical frame 16 without any gap. As is clear from FIG. 6, the circular holes 32a are arranged offset from the center line. This position is formed so that the center thereof corresponds to the position of the point P in FIG. 5 when the upper hinge 30 is attached to the vertical frame 16. By eccentricizing the position of the circular hole 32a of the housing 32, it is possible to mount an eccentric sliding door sash without adding a special device to the vertical frame.

FIGS. 10 to 13 are views showing a lower hinge attached to the vertical frame 16 of the movable side shoji 11, and show a front view, a bottom view, a side view and a vertical sectional view, respectively.
In each of these figures, the lower hinge 35 is constituted by a housing 37 fitted to the lower end of the vertical frame 16 and a rotating shaft 36. As shown in FIG. 13, the upper part of the rotating shaft 36 is
7 is rotatably accommodated in the circular hole 37a, and its lower part protrudes from the lower part of the vertical frame 16. A groove 36a is cut at the lower end of the rotating shaft 36, and loosely engages with the guide rail 2a of the lower frame. At the upper end of the rotating shaft 36, an engagement claw 36b for the housing 37 side is formed in order to prevent the pivot shaft 36 from coming off.

The casing 37 has substantially the same outer shape as the cross-sectional shape of the vertical frame 16, similarly to the casing 32, and is fitted into the vertical frame 16 without any gap. The position of the circular hole 37 a is arranged at a position corresponding to that of the upper hinge 30.

The structure of the upper hinge and the lower hinge provided on the fixed-side sash (shoji) 10 is as follows.
Except for having a configuration that cannot move with respect to 2a, it is basically the same as the upper hinge 30 and the lower hinge 35 of the movable-side sash 11 described above, and a description thereof will be omitted.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be embodied in various forms within the scope of the technical idea.

[0025]

As described above, according to the first aspect of the present invention, all or any part of the upper and lower frames and the left and right vertical frames are provided on the surface adjacent to the folding door shoji in the closed state. A waterproof member is provided, and the vertical stairs at the left and right ends of the folding door shoji,
In a state where the folding door shoji is closed, an outer surface having a substantially semicircular cross section is formed facing the vertical frame, and the folding door shoji is rotatable and / or slidable with respect to the upper and lower frames at upper and lower ends thereof. The hinge member, the hinge member, the rotation fulcrum with respect to the upper and lower frames, the center of the semicircle of the outer surface of the vertical frame, eccentric to the vertical frame side in the closed state of the folding door shoji. As a result, when the folding door is opened and closed, the vertical frame is positioned away from the waterproof member, and the frictional resistance between the folding door and the waterproof member during opening and closing can be extremely reduced. Opening and closing can be performed smoothly with a small force. Further, by reducing the friction between the waterproof member and the shoji, wear and deformation of the waterproof member can be minimized, and the watertightness of the waterproof member can be maintained for a long time. Further, since the friction against the waterproof member is small, an inexpensive and highly water-tight bead material can be used as the waterproof member as in the present invention described in claim 3.

According to a second aspect of the present invention, the hinge member is provided with a housing having a semicircular side surface substantially corresponding to the outer surface of the vertical frame, and the hinge member is eccentric with respect to the center of the semicircle of the housing. The eccentric structure can be achieved without adding any special measures to the vertical frame side by using a rotating shaft that is rotatably arranged at the specified position. A bathroom folding door with low frictional resistance between members can be configured very easily.
