  In addition, the above is an example of the installation method of the floor-standing guide rail 1, and the attachment order of each member can be appropriately changed as long as it can be attached. Moreover, although this embodiment renovates the existing hinged door to the sliding door, it is not limited to this, and a new sliding door can be similarly provided and used.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is the same as the first embodiment except that the structures of the rail receiving part 51 and the first deviation preventing part 52 are different. Therefore, the points other than the rail receiving part 51 and the first deviation preventing part 52 are the same. Description of is omitted. Further, as in the first embodiment, the mat receiving members 3 are provided on both sides in the prospective direction with respect to the rail body 2, and the basic structure is symmetrical, so the configuration of the mat receiving member 3 on the outdoor side is the same. I will explain.

  The rail receiving portion 51 in the second embodiment is suspended from the corresponding contact portion 51a and an inverted L-shaped contact portion 51a that contacts the lower end of the second side surface portion 2d of the rail body 2 and the lower side surface of the rail groove 2e. The bottom surface 51b is in contact with the floor surface F, and the second side surface portion 2d side of the rail body 2 is supported thereby. And the support surface 52a of the 1st deviation | shift prevention part 52 is extended in the prospective direction outer side of the contact part 51a.

  The first slip prevention portion 52 includes a support surface 52a extending horizontally from the floor F toward the outside in the prospective direction from the contact portion 51a of the rail receiving portion 51, and a rotation provided on an upper portion of the support surface 52a. A support member 53; a pressing member 54 that is rotatably fitted to the rotation support member 53; and a leaf spring 55 that bridges and biases the rotation support member 53 and the pressing member 54. . The pressing member 54 is urged in the rotational direction by the leaf spring 55, and has a posture of pressing the mat 4 against the support surface 52a at a thought point (dead point) and a posture of releasing the mat 4. It is energized to transform. Moreover, the 1st ditch | groove 7b is continuously provided in the prospective direction outer end part of the support surface 52a. Therefore, the laying surface 7f in the second embodiment is composed of the support surface 52a, the first inclined surface 7c, and the second inclined surface 7e that are on the outer side in the prospective direction than the rotation support portion 53.

  More specifically, the rotation support portion 53 is provided with a leaf spring support portion 53b having an opening portion 53a opened in a reverse C shape in a side view on the outer side in the prospective direction, and on the opposite side thereof. A rotation center portion 53c that is substantially circular in a side view is provided. On the other hand, when the mat 4 is pressed, the pressing member 54 is flat with the floor F, and the height from the floor F is substantially the same as the height of the upper surface portion 2c of the rail body 2, and the prospective direction rail body of the flat portion 54a. An inverted C-shaped fitting portion 54b that is provided on the second side and opens toward the outside in the prospective direction, projects downward from the prospective outer end portion of the flat surface portion 54a, and the tip portion is folded outward in the prospective direction. And a curved pressing portion 54c. The fitting part 54 b is rotatably fitted to the turning center part 53 c of the turning support part 53. On the prospective direction rail body 2 side of the pressing portion 54c, a leaf spring locking portion 54d that is notched in a substantially letter shape and that locks the end portion of the leaf spring 55 is provided. As will be described later, the tip of the pressing portion 54c is configured to press the rail body side edge portion 4d of the mat 4 laid on the support surface 52a by pressing by the leaf spring 55. Here, the flat surface portion 54a of the pressing member 54 is a surface that is continuous with the upper surface portion 2c of the rail body 2 in the pressing posture, and the support surface 52a of the laying surface 7f is lowered in a stepped manner with respect to the upper surface portion 2c. .

  The leaf spring 55 has one end portion 55 a in the prospective direction supported by the leaf spring support portion 53 b of the rotation support portion 53, while the other end portion 55 b is locked by the leaf spring locking portion 54 d of the pressing member 54. The rotation support portion 53 and the pressing member 54 are bridged and urged in an upwardly convex arcuate state. When the pressing member 54 rotates, the end portion 55a on the rotation support portion 53 side moves along the inverted C-shape of the leaf spring support portion 53b. At this time, the end portion 55a of the leaf spring 55 on the rotation support portion 53 side is an inverted C-shape of the opening 53a in the leaf spring support portion 53b when the leaf spring locking portion 54d of the pressing member 54 rotates downward. It moves upward along the shape and moves downward when it rotates in the opposite direction. By doing so, the urging direction of the pressing member 54 by the leaf spring 55 is switched to the upper side and the lower side with respect to the thought point (dead point). Therefore, in the pressing posture of the mat 4, the pressing member 54. , The pressing member 54 is biased downward by the leaf spring 55, and the rail body side edge 4d of the mat 4 on which the tip of the pressing portion 54c is laid is supported on the support surface 52a. (See FIG. 10A). On the other hand, when the position of the mat 4 is adjusted or the mat 4 is removed, the pressing member 54 is urged upward by the leaf spring 55 by rotating the pressing member 54 beyond the thought point. As a result, the state where the pressing of the mat 4 is released is maintained (see FIG. 10B).

  As described above, in the second embodiment, when the mat 4 is laid on the laying surface 7f, the rail body side edge portion 4d is laid so as to be positioned below the pressing portion 54c. By doing so, the mat 4 is pressed against the pressing portion 54c by the urging of the leaf spring 55, so that the displacement of the mat 4 can be better prevented. In addition, you may make it press the base fabric 4a of the mat 4 with the press part 54c as a site | part pressed down according to the thickness, material, etc. of a mat. Moreover, you may make it contact | abut the prospective direction outer side front-end | tip part of the plane part 54a with the side surface of the base fabric 4a like 1st Embodiment.

  In the first embodiment of the present invention configured as described, when the door body 101 opens and closes the opening O by driving the automatic door drive mechanism 105, the guided portion 101h at the lower end of the door body 101 is opened. The steady rest 101i is inserted into the rail groove 2e that is long in the direction of finding the rail body 2, thereby guiding the door 101 in the direction of finding and preventing the shake in the expected direction. It has become. And the mat | matte receiving member 3 is continuously provided in the prospective direction both sides of the rail body 2, and the horizontal surface 7a, the 1st inclined surface 7c, in order from the prospective direction rail body 2 side to the inclination part 7 of the mat | matte receiving member 3. A laying surface 7f including the second inclined surface 7e is provided, and the mat 4 is detachably laid on the laying surface 7f. Since the mat 4 is detachably laid in this way, it is easy to clean and replace a mat that is easily soiled to remove dirt and the like of shoes, and is excellent in maintainability. Moreover, since a commercially available mat can be laid, versatility is high. At this time, the horizontal surface 7a that is the end of the laying surface 7f on the rail body 2 side is an upper surface portion 6a of the rail receiving portion 6 that is a surface continuous with the upper surface portion 2c of the rail body 2 and the upper surface of the first deviation preventing portion 8. The height is lower stepwise than the portion 8a. For this reason, even when the mat 4 is laid, the laid mat 4 has a small amount of protrusion upward by the level difference, and the overall height of the floor-standing guide rail 1 does not increase, and the Does not hinder.

  In addition, the mat receiving member 3 is provided with a first slip prevention portion 8 so that the rail body side edge portion 4d of the mat 4 enters the space S2 of the first slip prevention portion 8 and the base cloth 4a of the mat 4 is provided. The rail body side surface is in contact with the front end portion 8b of the first displacement prevention portion 8, so that the displacement of the mat 4 is prevented. For this reason, the frequency | count of the maintenance operation | work which adjusts the position shift of the mat | matte accompanying many traffic can be reduced.

  Further, when the large mat 4B is laid, the outside in the prospective direction of the large mat 4B is laid on the floor F beyond the prospective outer end portion of the inclined portion 7. In this way, when the floor-standing guide rail 1 is provided in a place with a large space, the large mat 4B can be laid, and the inclined portion 7 has the first inclined surface 7c and the second inclined surface 7e. Therefore, the large mat 4B is laid on the floor F along the slope, and consideration is given so as not to scoop when passing.

  On the other hand, when laying the small mat 4A, the attachment 5 is provided at the prospective outer end of the floor-standing guide rail 1 as the second slip prevention portion, and the prospective outer edge 4e of the small mat 4A is the attachment 5. In addition to entering the space S3, the attachment side surface of the base cloth 4a of the mat 4 abuts against the tip 5h of the attachment 5, thereby preventing the mat 4 from being displaced. For this reason, the frequency | count of the maintenance operation | work which adjusts the position shift of the mat | matte accompanying many traffic can be reduced.

  Further, when the small mat 4A is laid, the attachment 5 is detachably attached to the attachment receiving portion 9, so that the end portion that is likely to cause scratches or deformation can be replaced simply by replacing the attachment 5. The maintenance work is easy and the replacement cost is low. The attachment 5 has a slanted portion whose height on the rail body 2 side is higher than the laying surface 7f, the height is lower toward the outer side in the prospective direction, and the outer end portion in the prospective direction is substantially the same height as the floor. Since 5b is provided, it is considered that a passerby, a luggage, etc. are not caught as a prospective direction outer side edge part of a floor-standing guide rail.

  Further, in the second embodiment of the present invention, as the first deviation prevention portion, the pressing member 54 that presses the mat 4 against the laying surface 7f by rotation or releases the mat 4, and the pressing member 54 A rotation support portion 53 in which the fitting portion 54b is rotatably supported by the rotation center portion 53c, and a leaf spring 55 in which an end portion is interposed between the pressing member 54 and the rotation support portion 53. And. The leaf spring 55 has an end portion 55a on the rotation support portion 53 side of the leaf spring 55. When the leaf spring locking portion 54d of the pressing member 54 is rotated downward, the leaf spring support portion 53b has an inverted C-shape. Since it moves upward along the shape and moves downward when it rotates in the opposite direction, the pressing member 54 is changed so that it changes into a posture that presses the mat 4 and a posture that opens the mat at the boundary of the thought point. It comes to be energized. For this reason, since the mat 4 is pressed against the pressing portion 54c by the bias of the leaf spring 55, the mat 4 can be better prevented from being displaced, while the mat 4 is removed or the position is adjusted. In some cases, by rotating the pressing member 54 upward beyond the thought point, the released state of the mat 4 is maintained, so that the work is facilitated.

  Needless to say, the present invention is not limited to the above-described embodiment. For example, as a simpler configuration, the mat receiving member 3 may not be provided with, for example, the rail receiving portion 6 and the first deviation preventing portion 8. At this time, the laying surface 7f is lowered stepwise with respect to the upper surface portion 6c of the rail, but the horizontal surface 7a of the laying surface 7f may be brought into contact with the second side surface portion 2d of the rail body 2, The mat 4 is prevented from being displaced by being inserted into the space 1 and having the upper surface portion 2c and the second side surface portion 2d of the rail body 2 having the same structure as the first displacement preventing portion 8 in the first embodiment described above. It is good also as what to do.
