And the screw hole 7i of the second concave groove 7d of the mat receiving member 3 are communicated with each other and screwed into the mat receiving member 3, so that the attachment 5 and the mat receiving member 3 are fixed to the floor F. On the other hand, the height of the inclined portion 5b is lower than the height of the upper surface portion 8a of the first deviation prevention portion, because the end portion on the side of the rail body 2 is located above the central portion in the prospective direction of the contact inclined surface 5f. ing. Further, although the tip portion 5h of the inclined portion 5b on the rail body 2 side hangs downward, it does not abut on the contact inclined surface 5f, and an opening portion 5i is formed. A space S3 is formed between the abutting portion 5a and the inclined portion 5b, and when the attachment 5 is attached, the outer edge portion 4e of the small mat 4A in the prospective direction is provided from the opening 5i to the space S3. A small mat 4A is laid by letting it enter. The mat 4 is prevented from being displaced by the attachment 5, but the details of the displacement prevention mechanism will be described separately in the section about the mat 4.

The mat 4 is a flat and flexible mat for a rectangular entrance that is long in the finding direction, and is a pile-shaped base cloth 4a that can remove stains on the sole and the base cloth. It is composed of a backing portion 4b on the back surface of 4a and an edge portion 4c on which the backing portion 4b extends from the four circumferences of the base cloth 4a. The mat 4 selectively selects a small mat 4A having a short prospective direction and a large mat 4B having a long prospective direction according to the size of the space for installing the floor-standing guide rail 1. It can be laid on the mat receiving member 3. In the present embodiment, the outdoor mat 4 has a thickness of about 14 mm and is made of polyvinyl chloride resin, whereas the indoor mat 4 has a thickness of about 10 mm and the base cloth 4a is nylon. The backing portion 4b is made of nitrile rubber. By using these materials, the frictional force between the backing portion 4b and the laying surface 7f becomes large, and the misalignment of the mat 4 is prevented. It goes without saying that the mat 4 is indoors and outdoors and the height and material must be different, and the material and thickness of the mat 4 can be changed as appropriate according to the purpose. Is. Further, the mat 4 does not necessarily have to have the above configuration, and may, for example, have no backing portion 4b or edge portion 4c, and is not limited to the material described above. Absent.

Here, when the rail body side edge portion 4d, which is the rail body 2 side edge portion 4c, is inserted into the space S2 of the first slip prevention portion 8, the side surface portion of the base cloth 4a on the rail body 2 side becomes the first. The end portion of the slip prevention portion 8 is adjusted so as to come into contact with the outer surface of the tip portion 8b in the prospective direction. That is, the length of the rail body side edge portion 4d is equal to or less than the length of the upper surface portion 8a of the first displacement prevention portion. As a result, when the mat 4 is laid, the side surface portion of the base cloth 4a comes into contact with the tip end portion 8b of the first displacement prevention portion 8, so that the mat 4 is prevented from being displaced toward the rail body 2 side as much as possible. You will be able to do it. Further, even if the mat 4 is slightly displaced toward the rail body 2, the tip end portion of the rail body side edge portion 4d will come into contact with the second side surface portion 6c of the rail body receiving portion 6, so that the position will be significantly increased. There is no deviation. Further, since the rail body side edge portion 4d is inserted into the space S2, it is prevented that the mat 4 is rolled up due to being caught by the rail body side edge portion 4d during passage.

As another mechanism for preventing misalignment, as shown in FIG. 4A, the space S2 including the end portion of the base cloth 4a is allowed to enter and is prevented from coming off by the tip portion 8b of the first misalignment prevention portion 8. May be. Further, as shown in FIG. 4B, a notch 4f may be provided at the upper end of the base cloth 4a, and the tip 8b of the first misalignment prevention portion 8 may be locked to the notch 4f. ..

When the mat 4 is a small mat 4A, the small mat 4A is laid by inserting the outer edge portion 4e of the small mat 4A in the prospective direction into the space S3 of the attachment 5. In this case, the prevention of misalignment by the attachment 5 is substantially the same as that of the first misalignment prevention portion, and when the outer edge portion 4e in the prospective direction is inserted into the space S3 of the attachment 5, the attachment 5 side of the base cloth 4a The end of the side surface of the inclined portion 5b is adjusted so as to come into contact with the side surface of the tip portion 5h of the inclined portion 5b on the side of the rail body 2.

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. Further, the present embodiment is obtained by remodeling an existing hinged door into a sliding door, but the present invention is not limited to this, and a newly installed sliding door can be similarly provided and used.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 10. The second embodiment is the same as the first embodiment except that the structures of the rail receiving portion 51 and the first slip prevention portion 52 are different. Therefore, points other than the rail receiving portion 51 and the first slip prevention portion 52. The description of the above will be 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 thereof is symmetrical. I will explain it.

The rail receiving portion 51 in the second embodiment has an inverted L-shaped contact portion 51a that abuts on the lower end of the second side surface portion 2d of the rail body 2 and the lower side surface on the rail groove 2e side, and hangs down from the corresponding contact portion 51a.

A support surface 52a of the first displacement prevention portion 52 extends outside the contact portion 51a in the prospective direction.

The first displacement prevention portion 52 includes a support surface 52a extending horizontally from the contact portion 51a of the rail receiving portion 51 toward the outside in the prospective direction with the floor F, and rotation provided on the upper portion of the support surface 52a. A support portion 53, a pressing member 54 rotatably fitted to the rotation support portion 53, and a leaf spring 55 for bridging and urging the rotation support portion 53 and the pressing member 54 are provided. .. Then, the pressing member 54 is urged in the rotation direction by the leaf spring 55, but the posture of pressing the mat 4 against the support surface 52a and the posture of releasing the mat 4 with the thought point (dead point) as a boundary. It is urged to transform into. Further, a first concave groove 7b is continuously provided at the outer end of the support surface 52a in the prospective direction. Therefore, the laying surface 7f in the second embodiment includes a support surface 52a outside the rotation support portion 53 in the prospective direction, a first inclined surface 7c, and a second inclined surface 7e.

More specifically, the rotation support portion 53 is provided with a leaf spring support portion 53b having an opening portion 53a that opens in an inverted C shape in the side view on the outside in the prospective direction, while the rotation support portion 53 is provided on the opposite side. A substantially circular rotation center portion 53c is provided on the side surface. On the other hand, the pressing member 54 has a flat surface portion 54a that is horizontal to the floor F when the mat 4 is pressed and whose height from the floor F is substantially the same as the height of the upper surface portion 2c of the rail body 2, and a rail body in the prospective direction of the flat surface portion 54a. An inverted C-shaped fitting portion 54b provided on two sides and opened outward in the prospective direction, and a flat surface portion 54a projecting downward from the outer end portion in the prospective direction, and the tip portion is folded outward in the prospective direction. It is composed of a curved pressing portion 54c. The fitting portion 54b is rotatably fitted to the rotation center portion 53c of the rotation support portion 53. A leaf spring locking portion 54d is provided on the side of the rail body 2 in the prospective direction of the pressing portion 54c, which is notched in a substantially square shape and locks the end portion of the leaf spring 55. Then, as will be described later, the tip portion of the pressing portion 54c is configured to press the rail body side edge portion 4d of the laid mat 4 against the support surface 52a by the urging by the leaf spring 55. Here, the flat surface portion 54a of the pressing member 54 is a surface 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 stepped lower than the upper surface portion 2c. ..

In the leaf spring 55, one end 55a in the prospective direction is supported by the leaf spring support 53b of the rotation support 53, while the other end 55b is locked by the leaf spring locking portion 54d of the pressing member 54. The rotation support portion 53 and the pressing member 54 are bridged and urged in an upwardly convex arc shape. Then, 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 has an inverted C shape of the opening portion 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 leaf spring 55 on the pressing member 54 is switched upward and downward with the thought point (dead point) as the boundary. Therefore, in the pressing posture of the mat 4, the pressing member 54 The pressing member 54 is urged 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 by the support surface 52a.

On the other hand, when adjusting the position of the mat 4 or removing the mat 4, the pressing member 54 is urged upward by the leaf spring 55 by rotating the pressing member 54 upward beyond the thought point. As a result, the state in which the mat 4 is released from being pressed is maintained (see FIG. 10B).

Then, 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 located 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 misalignment of the mat 4 can be better prevented. The base cloth 4a of the mat 4 may be pressed by the pressing portion 54c as a portion to be pressed, depending on the thickness and material of the mat. Further, as in the first embodiment, the outer tip portion of the flat surface portion 54a in the prospective direction may be brought into contact with the side surface of the base cloth 4a.

In the first embodiment of the present invention configured as described above, 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 The steady rest 101i is inserted into the rail groove 2e that is long in the finding direction of the rail body 2, whereby the door body 101 is guided in the finding direction and the runout in the prospective direction is prevented. It has become. Then, the mat receiving members 3 are continuously provided on both sides of the rail body 2 in the prospective direction, and the inclined portion 7 of the mat receiving member 3 has the horizontal plane 7a, the first inclined surface 7c, in order from the prospective direction rail body 2 side. A laying surface 7f composed of a second inclined surface 7e is provided, and a 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 the mat, which is easy to get dirty, because it removes dirt and the like from the shoes, and it is excellent in maintainability. In addition, since a commercially available mat can be laid, it is highly versatile. At this time, the horizontal surface 7a, which is the end of the laying surface 7f on the side of the rail body 2, is the upper surface of the rail receiving portion 6 and the upper surface of the first slip prevention portion 8 which are continuous surfaces with the upper surface portion 2c of the rail body 2. The height is stepped lower than that of the portion 8a. Therefore, even when the mat 4 is laid, the amount of protrusion of the laid mat 4 upward is reduced by the amount of the step, and the height of the entire floor-standing guide rail 1 is not increased, so that the mat 4 can pass through. It does not interfere.

Moreover, the mat receiving member 3 is provided with the 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 The misalignment of the mat 4 is prevented by abutting the side surface of the rail body side with the tip end portion 8b of the first misalignment prevention portion 8. Therefore, it is possible to reduce the number of maintenance operations for adjusting the misalignment of the mat due to a large number of passages.

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

On the other hand, when the small mat 4A is laid, an attachment 5 is provided at the outer end of the floor-standing guide rail 1 in the prospective direction as a second slip prevention portion, and the outer edge 4e of the small mat 4A in the prospective direction is the attachment 5. The mat 4 is prevented from being displaced by entering the space S3 of the mat 4 and the side surface of the base cloth 4a of the mat 4 in contact with the tip portion 5h of the attachment 5. Therefore, it is possible to reduce the number of maintenance operations for adjusting the misalignment of the mat due to a large number of passages.

Further, when the small mat 4A is laid, since the attachment 5 is detachably attached to the attachment receiving portion 9, it is possible to replace the end portion where the problem of scratches and deformation is likely to occur simply by replacing the attachment 5. It can be done, maintenance work is easy, and replacement cost is low. The height of the attachment 5 on the rail body 2 side is higher than that of the laying surface 7f, the height is lower toward the outside in the prospective direction, and the outer end in the prospective direction is an inclined portion inclined so as to be substantially the same height as the floor. Since it is equipped with 5b, consideration is given to prevent passers-by, luggage, etc. from being caught as the outer end of the floor-standing guide rail in the prospective direction.

Further, in the second embodiment of the present invention, as the first displacement prevention portion, the pressing member 54 that presses the mat 4 against the laying surface 7f or releases the mat 4 by rotation, and the pressing member 54. A leaf spring 55 whose end is interposed between the rotation support portion 53 in which the fitting portion 54b is rotatably supported by the rotation center portion 53c and the pressing member 54 and the rotation support portion 53. And have. The leaf spring 55 has an inverted C shape of the leaf spring support portion 53b when the leaf spring locking portion 54d of the pressing member 54 rotates downward at the end portion 55a of the leaf spring 55 on the rotation support portion 53 side. Since it moves upward along the shape and moves downward when it rotates in the opposite direction, the pressing member 54 is changed into a posture of pressing the mat 4 and a posture of opening the mat at the boundary of the thought point. It is supposed to be urged. Therefore, the mat 4 is pressed against the pressing portion 54c by the urging of the leaf spring 55, so that the misalignment of the mat 4 can be better prevented, while the mat 4 is removed or the position is adjusted. Occasionally, by rotating the pressing member 54 upward beyond the thought point, the open state of the mat 4 is maintained, so that the work becomes easier.

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 slip prevention portion 8. At this time, the laying surface 7f is lowered in a stepped manner 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 so that the upper surface portion 2c and the second side surface portion 2d of the rail body 2 have the same structure as the first displacement prevention portion 8 in the above-described first embodiment. It may be the one to do.

The present invention can be used in the field relating to a floor-standing guide rail which is arranged in the lower part of the door body and guides the opening and closing of the opening by moving the door body.
