Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame structure of a partition door in a general house or the like, and more particularly, to install a partition door such as a sliding door, a folding door or an opening door installed in a bathroom opening in a watertight manner. Regarding the lower frame structure of bathroom doors.

[0002]

2. Description of the Related Art There are three types of partition doors in general houses: sliding doors, folding doors, and open doors. These doors are configured so that a frame body composed of left and right vertical frames and upper and lower frames is fixed to an opening of a partition in the building, and is housed in the frame body. In the conventional bathroom door, the shape of the lower frame is such that the bathroom side of the lower frame upper surface is lowered and the dressing room side is raised so that the water accumulated on the lower frame upper surface flows down to the bathroom side. Also, the lower frame structure is a sliding door, folding door,
It was different depending on the type of partition door such as opening. For example, in the case of a sliding door, a rail or a groove for guiding the lower end of the door which is opened and closed in the longitudinal direction of the lower frame is provided on the lower surface of the lower frame on the bathroom side. And the watertightness inside and outside the bathroom is
It was ensured by fitting the lower end of the door into the rail or groove. Further, in the case of a folding door, a groove for guiding the lower end of one vertical frame moving in the longitudinal direction of the lower frame is provided on the lower surface of the upper surface of the lower frame on the bathroom side. The watertightness inside and outside the bathroom is ensured by providing a tight member between the side surface of the dressing room of the lower frame of the door and the vertical surface of the upper surface of the lower frame which stands up on the side of the dressing room. Further, in the case of opening the door, the rails or grooves provided in the case of the sliding door and the folding door are unnecessary, and the lower surface of the lower frame on the bathroom side is flat. The watertightness inside and outside the bathroom is ensured by providing a tight material between the side surface of the dressing room of the lower frame of the door and the vertical surface of the upper surface of the lower frame that stands up on the side of the dressing room, as in the case of the folding door. 5 is a vertical cross-sectional view showing an example of a conventional folding door type partition door used in a bathroom. The partition door in FIG. 5 is attached to a substantially rectangular opening C formed in the boundary wall between the bathroom A and the dressing room B, and the folding door is housed in a frame body consisting of left and right vertical frames and upper and lower frames. It In addition, the upper surface of the lower frame 101 is raised stepwise from the bathroom A to the dressing room B so that the accumulated water flows to the bathroom A side. A single tight member 103 is provided between the side surface of the lower frame 102 and the surface of the lower frame 101 standing on the dressing room B side to ensure water tightness inside and outside the bathroom.

[0003]

The upper surface of the lower frame of the conventional bathroom partition door is low on the bathroom side and high on the dressing room side so that water can flow to the bathroom side. Therefore, there is a step on the upper surface of the lower frame, and this step has to be straddled when a person goes in and out of the bathroom. Moreover, in the conventional lower frame structure,
It is not possible to use the same lower frame member because the structure for guiding the door track or the structure for ensuring watertightness inside and outside the bathroom differs depending on the type of door such as sliding door, folding door, and opening door. Therefore, since the lower frame material is manufactured, stocked, and assembled separately for each type of door, an increase in cost is inevitable. In view of the above problems, the present invention eliminates the step on the upper surface of the lower frame so that it becomes easy when a person goes in and out, and the same lower frame member is used even if the types of doors such as sliding doors, folding doors, and opening doors are different. The present invention provides a lower frame structure for a bathroom door that can be used and has excellent drainage and watertightness.

[0004]

In order to solve the above problems, in the lower frame structure of the bathroom door of the present invention, it is mounted in a frame member having an upper frame having a track and a lower frame having a guide groove. Partitioning doors such as sliding doors, folding doors, and open doors can be installed in a watertight manner, and rising pieces whose upper part is a horizontal surface are formed on the lower frame, and drainage grooves are formed on the lower frame and rising pieces. And, the auxiliary lower frame whose upper part is a horizontal surface is formed on the bathroom side, and the guide groove of the lower frame is formed between the auxiliary lower frame and the rising piece. The horizontal surface of the upper part of the auxiliary lower frame is installed at almost the same height as the inner edge of the lower frame, and the two tight members attached to the lower end surface of the partition door come into contact with the lower frame in a watertight manner. It is designed to provide a double watertight structure. Further, in a preferred embodiment of this aspect, a backflow preventing sealing material is provided substantially horizontally from the auxiliary lower frame toward the rising piece.

[0005]

[Operation] A drainage groove formed by the lower frame and the rising piece,
The guide groove between the auxiliary lower frame and the rising piece has a function of causing the water accumulated on the upper surface of the lower frame to flow back to the bathroom side. In the case of a sliding door or a folding door, the guide groove also has a function of guiding a movement of the door by fitting a guide piece provided at the lower end of the partition door. Since the horizontal surface above the rising piece and the horizontal surface above the auxiliary lower frame and the upper surface of the inner edge of the lower frame are installed at approximately the same height, the lower frame is used when a person passes through the inside and outside of the partition door. It makes it easy to get in and out without getting on it. or,
The double-tight material attached to the lower end surface of the partition door water-tightly contacts the horizontal surface of the rising piece and the upper horizontal surface of the auxiliary lower frame to provide a double water-tight structure for the lower frame. Even if water is violently sprayed from above, the water does not flow down into the guide groove between the first tight material and the second tight material and does not enter the dressing room side. Furthermore, when a large amount of water is poured into the washing area in the bathroom by installing a backflow prevention seal material almost horizontally from the auxiliary bottom frame toward the rising piece, and the water flows back from the drain hole provided in the bottom frame. However, since water is blocked by the backflow prevention sealing material, it does not blow out from the upper portion of the lower frame.

In this way, the guide piece 84 is attached to the lower side so as to slide in the guide groove 50a of the lower frame 50. The vertical frames 72c and 72d in the middle part are
It is foldably supported by a support member 80 provided between them.

Next, when the door is pulled toward the bathroom A side, the folding door 7
0 folds at the support member 80, and half of the folding door 70 rotates about the rotation axis. A hanging door pulley 88 attached to the other half of the folding door 70 rolls on the guide rail 40a, and a guide piece 84 slides in a guide groove 50a provided in the lower frame 50. In such a bathroom door,
The present invention is characterized by the shape of the lower frame portion, the drainage structure, the watertight structure with the door, and the like. On the upper part of the lower frame 50, an auxiliary lower frame 52 is formed on the bathroom A side, an indoor edge 56 is formed on the dressing room B side, and a rising piece 54 is formed between them. The auxiliary lower frame 52, the interior edge 56, and the rising piece 54 have horizontal planes of substantially the same height at the top. The space between the auxiliary lower frame 52 and the rising piece 54 is
The guide groove 50a that guides the track of the guide piece 84, and the space formed between the rising piece 54 and the portion that rises toward the indoor edge 56 of the lower frame 50 becomes the drain groove 50b that drains water.

As described above, the lower frame 50 is the auxiliary lower frame 52.
Since the upper surface, the upper surface of the rising piece 54 and the upper surface of the indoor edge 56 have substantially the same height and no step, the lower frame can be used as a footrest when a person goes in and out of the room. Further, if a sludge having substantially the same height as the upper surface of the auxiliary lower frame 52 is laid on the side of the bathroom A, the floor from the changing room B to the upper surface of the sludge becomes a substantially flat surface, which further enhances the safety and the wheelchair. Even the person who uses it can enter the bathroom A as it is. As best shown in FIG. 3, a drain hole 50 c is provided in the lower portion of the auxiliary lower frame 52, and the drain hole 5 c is also provided in the lower portion of the rising piece 54.
0d is provided. Therefore, even when a person passes through the lower frame 50 with a wet body and water drips, the water dripping on the upper surface of the lower frame 50 flows down into the guide groove 50a or the drain groove 50b, and the drain hole 5 is formed.
It quickly flows out to the bathroom A side through 0c and 50d. The auxiliary lower frame 52 is provided separately from the lower frame 50 (first embodiment of FIG. 1), but forms the drain hole 50c as shown in FIG. You may provide integrally by a lower piece. Two tight members 82, 82 are provided on the lower end surface of the lower frame 72f. When the folding door 70 is closed, these two tight members 82, 82 are
The tight surface 52a (horizontal surface) provided on the upper surface of the auxiliary lower frame 52 and the tight surface 5 provided on the upper surface of the rising piece 54.
Double contact with 4a (horizontal plane) in a watertight manner. As a result, even if the water strongly blown to the lower end of the partition door invades from between the tight material 82 on the bathroom A side and the tight surface 52a, the intruded water is blocked by the tight material 82 on the dressing room B side. It flows down into the guide groove 50a. The two tight members 82, 82 are preferably made of an elastic material such as rubber.

A guide groove 50 for guiding the above-mentioned door track.
The structure of a and the double seal structure of the tight members 82, 82 can be used as they are, regardless of the type of partition door such as a sliding door and an opening door other than the above folding door. As a result, the same member can be used for the lower frame 50 regardless of the type of door. For example, in the case of a sliding door as shown in FIG. 4A, if a guide piece that engages with the guide groove 50a of the lower frame 50 and two tight members 82, 82 are provided in the lower portion of the lower frame, the guide groove 50a can be provided. Acts as a guide when the sliding door opens and closes in the longitudinal direction of the lower frame. On the other hand, since the two tight members 82, 82 are in contact with the tight surfaces 52a, 54a to ensure watertightness as in the case of the folding door, the lower frame 50 is made of the same member as that used for the folding door. it can.

Further, in the case of the open door as shown in FIG. 4 (c), since the opening / closing direction of the door is a fan shape centering on the rotation axis provided on one of the left and right vertical frames, the folding door and the sliding door described above. In this case, the guide piece 84 provided on the lower portion of the lower frame is unnecessary, and the guide groove 50a of the lower frame 50 acts only as a drain groove.
Further, if two tight members 82, 82 are provided under the lower frame of the door, the two tight members 82, 82 contact the tight surfaces 52a, 54a as in the case of the folding door and the sliding door described above. It acts to ensure watertightness. Therefore, the lower frame 50
The same members as those used for the folding door and the sliding door can be used. Further, since the lower frame structure of the present invention has a common structure regardless of the type of sliding door, folding door, and opening door, there is an effect that it can be changed to another type of door even after the partition door is installed. For example, even after the folding door type partition door is installed as in the present embodiment, it is possible to change to an opening door in which the rotary shafts are attached only to the upper and lower limits on the rotary shaft side of the door. Further, in this embodiment, the guide groove 50
A backflow preventing sealing material 58 is provided below the a so as to project from the auxiliary lower frame 52 to the rising piece 54 side. The backflow preventing sealing material 58 allows a large amount of water to flow when cleaning the washing place in the bathroom A and the like, and when the water flows back from the drain hole 50c provided in the lower frame, the guide groove 50a and the drain groove 50b.
To prevent it from overflowing. The frame material, the frame material, and the like described above are formed by an aluminum extrusion mold material.

Next, an application example in which the lower frame structure of the present invention is used for a partition door other than a bathroom will be described. The partition door according to the present invention can make the upper surface of the lower frame substantially flat, has good water-tightness, and is excellent in drainage, so that it can be used in a toilet, a closet, or between a balcony and a room. Also suitable as a partition door. Further, since the double seal structure of the present invention has excellent inner and outer airtightness, if it is used for a door of a shoe box, furniture or the like, invasion of harmful insects can be easily prevented.

[0013]

Since the present invention is configured as described above, it has the following effects. The upper surface of the lower frame has a horizontal surface above the rising piece and an upper horizontal surface of the auxiliary lower frame, and the upper surface of the indoor edge of the lower frame is set at substantially the same height. In addition, it can be used as a foothold without straddling the lower frame to facilitate the entrance and exit of the room. It is especially suitable for the entry and exit of old people and children. Further, if a slatting board having substantially the same height as the upper surface of the auxiliary lower frame is laid on the bathroom side, the floor of the dressing room, the upper surface of the lower frame, and the upper surface of the inner edge become substantially flat, which further enhances safety. Drainage holes are provided in the lower part of the auxiliary lower frame and the lower part of the rising piece respectively, and even if water splashes on the upper surface of the lower frame, the water will flow down to the guide groove and the drainage hole and the bathroom will be released quickly. Because it is returned to the side, water is not accumulated on the lower frame for a long time and it is very clean. In the invention provided with the backflow prevention seal material, a large amount of water is flushed for cleaning the washing place in the bathroom, etc., and even when the water flows back from the drain holes provided in the lower frame,
Since water is blocked by the backflow prevention sealing material, there is no possibility that water will blow out from the lower frame and flow to the dressing room side.
Further, in the lower frame structure of the present invention, since the double seal structure is formed by the two tight materials, even if water is strongly blown to the lower end of the partition door, the water is the first tight material and the second tight material. It will not flow down into the guide groove between the material and enter the dressing room side. Further, in the lower frame structure of the present invention, the same watertight structure can be provided regardless of the type of the partition door such as a sliding door, a folding door, and an opening door, and the same guide groove is provided for each type of partition door. Therefore, the lower frame member can be used as a common component. Further, by this, when it is desired to change the type of the door after the partition door is installed, the lower frame member does not have to be replaced, and therefore the door can be easily replaced with a different type.
