[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sash lower frame structure for a door car suitable for use as a partition for bathrooms, entrances, living rooms, and the like.

[0002]

[Prior Art]

 In the past, Japanese Utility Model Publication No. 1-20466 discloses a device for a doorway part of a bathroom in which a sash on the lower frame of the doorway is flat so that the user can enter and leave the bathroom in a wheelchair. This entrance / exit is a flat entrance / exit bottom frame, with the upper edges of the protrusions, such as the lower guide rails on which the doors are placed, provided at the same height as the floor. Then, if the lower frame of the entrance / exit is set at the same height as the floor, it is necessary to prevent water from flowing out from the bathroom side. For this reason, in the conventional device, the lower guide rail has a drain hole.

[0003]

[Problems to be solved by the device]

 However, in the conventional entrance / exit structure, the lower guide rail on which the door roller is placed and the inclined piece supporting the lower guide rail are integrally formed. It is necessary to open the hole. As a result, the strength of the lower guide rail may decrease due to the opening of the water drain hole. In addition, the work of opening and closing the water draining hole is troublesome, and a drainage hole that is drilled on the side surface of the ridge such as a rail does not provide a sufficient drainage effect, and it always slips out into the lower guide rail. There were also sanitary issues such as the accumulation of uncut water.

Therefore, the present invention has been devised to solve the above-mentioned problems, and construction work is easy, structural strength is excellent, and drainage in a groove formed in the sash lower frame is performed. The purpose of the present invention is to provide a sash lower frame structure for door cars that has good properties.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention is a guide projecting downward from a side surface of a door roller P2 on an upper surface of an upper frame body 1 having a flat mounting surface portion on which the door roller P2 rotates on the ground. A guide groove portion 1A for inserting the piece P1 is provided. Then, a water drain hole 1B is opened on the bottom surface of the guide groove portion 1A. On the other hand, a lower frame body 2 on which the upper frame body 1 is installed is provided. The lower frame 2 is provided with an inclined middle plate 2A, and a drain port 2D communicating with the drain hole 1B is provided on the side plate along the upper surface of the middle plate 2A. To do.

[0006]

[Action]

 According to this invention, since the upper frame 1 and the lower frame 2 can be freely combined, the drain hole 2D is formed afterward when the lower frame sash is installed. Then, the water flowing in from the recess 1A of the upper frame 1 is returned to the bathroom or the like through the drain hole 2D.

The recess 1A is for inserting the insertion plate P1 of the hanging door P, and the drain plate P2 provided on the insertion plate P1 prevents the water from flowing out of the bathroom.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. This invention sash lower frame structure is composed of an upper frame body 1, a lower frame body 2, and a guide piece P1 projecting downward from the side surface of the door roller P2. The upper frame 1 has a flat mounting surface portion on which the door roller P2 rotates about the ground, and is mounted and fixed on the lower frame 2.

The upper frame 1 is, for example, in order to allow a physically handicapped person to enter and leave a bathroom in a wheelchair, a lower frame of an entrance / exit is provided on a floor part such as a slatted room inside the bathroom or a floor surface outside the bathroom. It is provided so that the height of the sash is uniform. Further, the upper frame 1 has a guide groove portion 1A into which the insertion plate P1 at the lower end of the sliding door P 1 is inserted, and a drain hole 1B is opened at the bottom portion of the guide groove portion 1A. Therefore, when the water in the bathroom is scattered, the insertion plate P1 of the sliding door P prevents the water from flowing out, and the water flowing from the insertion plate P1 into the guide groove portion 1A passes from the water drain hole 1B to the middle plate 2A, It is returned to the inside of the bathroom from the drain hole 2D. Although the upper frame body 1 shown in FIG. 1 has one guide groove portion 1A, a plurality of guide groove portions 1A may be formed (see FIG. 3). At this time, when one sliding door P is used for the sash in which the plurality of guide groove portions 1A are formed, there is an advantage that the unused guide groove portion 1A acts as drainage. The drainage hole 1B opened in the guide groove portion 1A can be formed in a long hole shape, for example, to enhance the drainage effect.

The lower frame body 2 is placed on the frame Q, and the upper frame body 1 is placed and fixed on the upper portion of the lower frame body 2. The combined structure of the upper frame body 1 and the lower frame body 2 is, for example, a structure in which the upper end of the support plate 2B of the lower frame body 2 and the upper frame body 1 are slidably fitted together, as in the illustrated connecting portion 3. Although it is predetermined, other connecting means may be used, and the point is that the upper frame body 1 and the lower frame body 2 can be combined and integrated when the lower frame sash is installed. Further, the lower frame 2 is provided with an intermediate plate 2A having an inclination in which water flows in the bathroom or the like. The middle plate 2A extends laterally and is inclined, and side plates are provided along the upper surface of the middle plate 2A. In the figure, a drainage hole 2D is opened in the plate surface of the reinforcing plate 2C and one side plate of the lower frame body 2 (see FIG. 1).

The guide pieces P1 of the sliding door P are provided at appropriate positions on a draining plate made of thin aluminum or the like provided in a strip shape along the longitudinal direction of the guide groove portion 1A. A guide cap P3 made of plastic or the like is attached to the tip of the guide piece P1 inserted in the guide groove portion 1A in order to suppress rattling when the door roller P2 is opened and closed.

Then, a ridge-shaped closing member P4 is provided at a portion of the sliding door P that abuts on the upright W, and a contact plate T is provided on a side surface of the upright W on which the sliding door P abuts. At both ends of the contact plate body T, rubber cushioning bodies U protruding in the sliding door P direction are provided. This prevents water from leaking from the side surface of the sliding door P, and is safe even if a finger is accidentally pinched between the sliding door P and the contact plate T.

Although the tile R is used in the drawing on the bathroom side, it is also possible to use a drainboard. Further, the sash lower frame structure of the present invention can be used not only as a bathroom but also as a partition from the entrance or living room to the garden.

[0014]

[Effect of the device]

 The present invention achieves the original purpose by being configured as described above. That is, a guide groove portion 1A for inserting the guide piece P1 protruding downward from the side surface of the door roller P2 is provided on the upper surface of the upper frame 1 having a flat mounting surface portion for the door roller P2 to rotate on the ground, and the bottom surface of this guide groove portion 1A. The lower frame 2 is provided with a drainage hole 1B, and the lower frame 2 is provided with an inclined middle plate 2A. The drainage port 2D communicating with this drainage hole 1B is provided on the upper face of the middle plate 2A. By providing it on the side plate along with, the drainage property in the recess formed in the sash lower frame was improved. Further, even if the water drain hole 1B is opened in the guide groove portion 1A of the upper frame body 1, sufficient strength can be obtained by combining the lower frame body 2 under the upper frame body 1.

Moreover, since the upper frame body 1 is installed on the lower frame body 2, there is an advantage that construction work can be performed extremely easily.

As described above, according to the present invention, the construction work is easy, the structural strength is excellent, and the drainage property in the groove formed in the sash lower frame is good, which is a practical advantage. It has various various effects.
