[0005]

According to the present invention, the following effects can be obtained by the above-described configuration. According to the first aspect of the present invention, since the guide groove is covered with the flexible cover, dirt, dust, and the like hardly accumulate in the guide groove, and the appearance is improved as if there is no guide groove. You can do it. Ma
The wheel is placed on the inclined receiving surface via the flexible cover
In other words, the flexible covering acts as a cushioning material
Open and close the sliding door smoothly and quietly
You can do it. Further, a hanging member connected to the flexible cover is provided.
The flexible covering is removed simply by fitting the lower fitting ridge into the fitting groove.
The hanging fitting ridges
You can remove the flexible covering just by pulling it out of
Therefore, it is easy to replace the flexible cover. The invention of claim 2
According to this, in a state where the sliding door is completely deviated to either the left or right, the mounting position of the wheel with respect to the sliding door can be adjusted so that the wheel rests only on the flexible cover on the side on which the sliding door is deviated. For example, in a state where the sliding door is biased to the right or left, the entire flexible cover on which the sliding door is not placed, that is, the flexible cover of a portion that is easily visible is in a horizontal state, so that the appearance is good. According to the invention of claim 3,
If the sliding door is completely offset to either the left or right and the mounting position of the wheel with respect to the sliding door is adjusted so that the wheel rests only on the flexible cover on the side where the sliding door is offset, the sliding door can be moved. In the state where the flexible cover is shifted to the right or left, the flexible cover on the side opposite to the center of the flexible cover and the side opposite to the sliding door, that is, the flexible cover on the easily visible portion is in a horizontal state, so that the appearance is improved. Good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings based on two embodiments. In these examples, the same members are denoted by the same reference numerals.

Embodiment 1 (see FIGS. 1 to 5) In Embodiment 1, the front side of FIG.
The back means the back side, the left means the left side in FIG. 1, and the right means the right side in the figure.

The sliding door device 1 has a frame 2 and two front and rear sliding doors 3.

The frame 2 comprises a pair of left and right vertical frame members 6 made of an extruded aluminum member, and a pair of front and rear lower rails 7 made of an aluminum extruded member and the like, which extend below the vertical frame members 6. And a pair of front and rear upper rails 8 made of an extruded aluminum member and the like, which are passed over the vertical frame member 6.

A guide groove 11 is formed along the lower rail 7 and a pair of front and rear inclined receiving surfaces 12 are formed in front and rear portions of the guide groove 11 and are inclined downward toward the center in the front-rear direction. . A flange fitting portion 13 is formed between the inclined receiving surfaces 12. The fitting groove 1 is formed along the guide groove 11 at the front and rear edges of the guide groove 11 of the lower rail 7.
4, a narrow portion (a narrow portion narrower than the inner portion) is formed near the upper portion of the fitting groove 14.
In addition, a hanging, less flexible or inflexible fitting ridge 18 continuously provided on a pair of front and rear flexible coverings 17 long in the left-right direction is detachable in a forcedly fitted state. It is fitted in. When no force is applied to the front and rear flexible coverings 17, the free edges are opposed to each other so that the flexible coverings 17 are horizontal with their elasticity and cover the guide groove 11 almost or completely. The flexible cover 17 attached to one lower rail 7 is divided at the center in the left-right direction or substantially at the center. The reason will be described later.

Concave portions 21 which are open downward are formed in the lower left and right portions of the sliding door 3, and a door wheel 22 is housed and mounted in these concave portions 21. The door roller 22 has a metal casing 23 and a synthetic resin wheel 24 rotatably provided on the casing 23 so that an axis thereof is directed in the front-rear direction. The wheel 24 has a flexible cover on a flange portion 24a which is located at the center in the front-rear direction and which fits into the flange portion fitting portion 13 and an inclined receiving surface 12 of the lower rail 7 provided on the front and rear portions of the flange portion 24a. 17 from above. When the wheel 24, more specifically, the flange portion 24 a is placed on the flexible cover 17, the flexible cover 17
In this state, the front and rear widths are set so as not to protrude (expose greatly) toward the flange fitting portion 13 in this state. As is clear from this description,
The left and right portions of the flexible cover 17 near the wheel 24 are the wheels 24.
It is in a state of being depressed toward the side. By the way, as described above, since the flexible cover 17 is divided at the center or substantially the center in the left-right direction, when the sliding door 3 is completely deviated to either the left or right, the sliding cover 3 The flexible shroud 17 that has become free, i.e., has no or little under the sliding door 3, is horizontal. In a state where the sliding door 3 is completely deviated to one of the left and right sides, the mounting position of the wheel 24 with respect to the sliding door 3 is adjusted so that the wheel 24 is placed only on the flexible cover 17 on the side where the sliding door 3 is deviated. Have been.

A guide groove 28 is formed on the upper rail 8 along the upper rail 8, and a roller 29 provided on the upper right and left sides of the sliding door 3 so that the axis thereof is directed vertically is fitted into the guide groove 28. Have been.

Second Embodiment (See FIG. 6) In this second embodiment, the front means the lower side of FIG. 6, the rear means the upper side of the figure, the left means the left side of FIG. 6, and the right means the same. Refers to the right side of the figure. The front and rear flexible covers 17 are cut off at a position offset left and right by a predetermined length α with respect to the center position A in the left-right direction as a boundary, and divided into a left portion 17a, a center portion 17b, and a right portion 17c. I have. Then, in a state where the sliding door 3 is completely deviated to either the left or the right, the wheel 24 on the center side is prevented from resting on the center portion 17b. With such a configuration, when the sliding door 3 is completely deviated to either the left or right, the central portion 17b of the flexible cover 17 released from the wheels 24 of the sliding door 3 and the side opposite to the sliding door 3 Part of the flexible cover 17 (left part 17)
a or the right portion 17c) is in a horizontal state.

[0014]

[Modifications and the like] Modifications and the like will be described below. (1) The wheel 24 is merely a short columnar shape, and the front and rear peripheral corners are inclined from the flexible cover 17 on the inclined receiving surface 12.
It may be something like that described in. (2) The upper rail 8 includes a Kamoi. (3) The upper portion of the sliding door 3 may be directly fitted into the guide groove 28 of the upper rail 8 without the roller 29.
