When washing water, rain water, etc. accumulate in the guide groove 2, it is sucked by a mop or the like. Or, waiting for natural evaporation. In addition, dirt, dust and the like enter the guide groove together with rainwater and accumulate.

[0003]

However, the guide grooves 2
The drainage work of sucking washing water and rainwater collected in a mop, etc., is not annoying, and it is necessary to wait for spontaneous evaporation.However, when rainwater contains dirt and dust, this can cause bacteria. The culture medium is scattered due to bacterial growth, and is transplanted from one step to another when the worker walks, thereby impairing hygiene.

Further, when dirt, dust, and the like are gradually taken out of the guide groove 2 without being taken out from the guide groove 2, the dirt, dust, etc. are guided each time the guide rod 4 moves through the guide groove 2 by opening and closing the sliding door 1. Extruded from groove 2 and soiled floor.
Further, accumulated dirt, dust and the like adhere to the inner wall of the guide groove 2, and the guide rod 4 of the sliding door cannot move smoothly in the guide groove, which hinders the opening and closing of the sliding door 1.

Further, since drainage by natural evaporation requires a long time, when the material of the guide groove 2 is a metal such as iron, rust is easily generated, and the opening and closing of the sliding door 1 is not smooth. Therefore, the durability of the guide groove 2 is reduced.

An object of the present invention is to solve such a problem of the prior art, and an object of the present invention is to provide a simple guide groove for a sliding door which can smoothly drain the guide groove.

[0007]

To achieve the above object, the present invention provides a hanger provided to open and close an opening in a room.
A guide groove on the floor side of the sliding door, and a groove continuously interposed in the guide groove, having a width substantially equal to the width of the guide groove, and connected to the side wall of the guide groove in a flush manner. A circle having a diameter larger than the width, which is connected to an introduction portion and a groove opening is provided below the groove introduction portion.
It is composed of a groove body having a shape cross section, the groove inlet portion
And the inner wall surface of the groove body has a smooth surface structure, and the groove body
Is inclined from the upstream side to the downstream side in the longitudinal direction of the groove body and
It has a discharge port at the flow end .

[0008]

In the above construction, washing water, rainwater, etc., flowing into the guide groove fall from the groove introduction portion into the groove main body through the groove opening, and are drained outward.

A groove main body 13 (FIG. 2) which is connected and has a pipe section having a gentle slope as shown in FIG. 1 and having a diameter larger than the width of the gap between the side walls 5 (FIG. 2).
And an elbow 14 (FIG. 4) provided at the downstream end of the groove main body 13. The drain groove 3 is made of stainless steel to have a smooth surface structure.

[0013] As shown in FIG.
The side walls (vertical walls) 15 opposing each other at the same interval as the side walls 5 of the original guide groove 2 also serve as upper and lower heights of the side walls 5 of the original guide groove 2 at the upstream end. At the downstream end, it is longer than the depth of the side wall 5 of the guide groove 2 (FIG. 4). The change in the depth of the groove introduction portion 11 from the upstream side to the downstream side corresponds to the gradient of the groove main body 13 where the downstream side becomes lower , and gradually increases from the upstream side to the downstream side. A horizontal portion may be provided at the upper end of the groove introduction portion 11, that is, the side wall portion 15, to be flush with the floor surface. When increasing or decreasing the height of the groove introducing portion 11 or increasing the overall height, it can be adjusted by adding another plate-like pair.

The groove main body 13 is formed in a pipe shape having a diameter larger than the gap width of the groove introduction portion 11, and an opening 12 having the same width as the gap width is formed above the groove main body 13 in the axial direction.
Has been established. The groove main body 13 is connected to the groove introduction portion 11
The cross-sectional shape is larger than the gap width of
A lot of water, rainwater, dirt, dust, etc.
11 and flow into the groove body 13
The water cannot be discharged into the water basin and flows backward to the guide groove 2 or clogs
And the lower part of the groove body 13 is curved
