Further, the concave step portion 22 has a shape corresponding to the outer peripheral shape of the flange portion 17 of the case 14, and the flange member 20 in a state where the flange portion 17 of the case 14 is received by the concave step portion 22. It is set as the structure which controls the movement to the floor 4 surface area direction of the case 14 with respect to.

In the present embodiment, the concave step portion 22 has a shape corresponding to the flange portion 17 of the case 14. That is, the concave step portion 22 has a step wall surface that is in contact with or close to the outer peripheral side surface of the hook-shaped portion 17 and a tapered surface that is in contact with or close to the taper surface of the hook-shaped portion 17.
Further, in the illustrated example, the bottom surface of the flange portion 17 and the bottom surface of the flange member 20 are substantially flush with the concave step portion 22 in a state where the flange portion 17 of the case 14 is received in the concave step portion 22. Is formed. In addition, as the concave step portion 22, a flange-like portion (upper peripheral portion) 17 of the case 14 is brought into contact with a step bottom surface (tapered surface in the illustrated example) facing the lower surface side, and on the center side of the opening 21. It is good also as what the outer peripheral side surface of the bowl-shaped part (upper-end peripheral part) 17 of the case 14 contact | abuts or adjoins to the stepped wall surface which faces. For example, the step bottom may not be a tapered surface as described above, but may be a flat surface parallel to the floor 4. In addition, the lower surface of the hook-shaped portion 17 may be positioned above or below the lower surface of the flange member 20 in a state where the hook-shaped portion 17 of the case 14 is received in the concave stepped portion 22.

In the present embodiment, the flange member 20 is provided with a stopper insertion hole 25 through which the stopper 7 for fixing the flange member 20 to the floor 4 is inserted. The stopper insertion hole 25 is provided through the flange member 20 in the thickness direction. In the illustrated example, a plurality of (four in the illustrated example) fastener insertion holes 25 are provided in the vicinity of the periphery of the flange member 20 at substantially equal intervals along the circumferential direction. Further, in the illustrated example, a stopper insertion hole 25 in which the upper portion has a large diameter that serves as a head receiving recess of the stopper 7 is illustrated.
The flange member 20 may be formed of a metal material or the like.

The stopper 7 may be appropriately selected according to the floor 4 as an attachment target as described above. For example, a stopper for concrete that can obtain a relatively high holding force for the concrete as described above. It is good also as the tool 7. Such a fastener 7 includes, for example, an anchor plug provided with a female screw portion that is driven into a fastener hole formed in the floor 4 and a bolt that is screwed into the female screw portion. You may make it use the anchor bolt etc. for concrete that a plug expands and is fixed.
The stopper 7 having such an anchor plug may have a structure in which a diameter-expanded portion of the anchor plug is expanded by being driven into the stopper hole and fixed to the stopper hole, or A structure may be adopted in which a diameter-enlarged portion of the anchor plug is expanded and fixed to the stopper hole with the screwing of the bolt to the female thread portion of the anchor plug.
In the illustrated example, the number of the fastener insertion holes 25 is four. However, the number of the fastener insertion holes 25 is not limited, and an appropriate number is used from the viewpoint of fixing strength of the flange member 20 to the floor 4. The stopper insertion hole 25 may be provided in the flange member 20.

As a construction aspect of the sliding door guide device 1 having the above-described configuration, first, the accommodation hole 5 for accommodating the guide device main body 10 is formed in the floor 4 as shown in FIG. Since it is difficult to accurately form the accommodation hole 5 in the floor 4 as described above, the accommodation hole 5 may be formed to have a diameter slightly larger than the outer diameter of the case 14. The diameter of the receiving hole 5 may be smaller than the diameter of the flange member 20 and a diameter that allows the flange member 20 to be fixed to the floor 4. When the stopper insertion hole 25 of the stopper 7 is provided in the flange member 20 as in the present embodiment, the stopper insertion is performed in consideration of the fixing strength of the flange member 20 to the floor 4 by the stopper 7. The accommodation hole 5 may be formed so as to have a smaller diameter than the portion where the hole 25 is provided. In addition, the depth dimension of the accommodation hole 5 is larger than the dimension obtained by adding the thickness dimension of the elastic member 16 in the maximum compression state to the thickness dimension (vertical dimension) of the lower portion of the case 14, and It is good also as a dimension smaller than the dimension which added the thickness dimension of the elastic member 16 made into the natural state to the thickness dimension (vertical dimension) of the lower side part of case 14. FIG.
As described above, in this embodiment, since the elastic member 16 is provided in the case 14, the necessity to form the receiving hole 5 with high accuracy in the depth dimension is reduced, and the receiving hole 5 is formed deeper. You may make it do.
Next, the guide device main body 10 is accommodated in the accommodation hole 5 formed in the floor 4. Next, the flange member 20 is disposed so as to be pressed against the floor 4 from above so that the flange portion 17 of the case 14 is pressed from above, and the stopper 7 is inserted into the stopper insertion hole 25 of the flange member 20. The flange member 20 may be fixed to the floor 4.

Further, when the suspension door guide device 1 is constructed in this way, the position of the lifting body 11 may be adjusted so as to be positioned at the center of the groove width direction of the guide groove 3 of the suspension door 2.
As an aspect of such position adjustment, for example, the case 14 may be accommodated in the accommodation hole 5 and the position adjustment may be performed in a state where the flange member 20 is temporarily fixed to the floor 4. In this case, the flange member 20 may be permanently fixed to the floor 4 after adjusting the position of the elevating body 11. Further, when the elastic member 16 is provided at the bottom of the case 14 as in the present embodiment, the elevating body 11 is raised in a state where the case 14 is accommodated in the accommodation hole 5 and the flange member 20 is fixed to the floor 4. The position of the elevating body 11 may be adjusted by pushing the case 14 so that the elastic member 16 is elastically deformed. Further, when adjusting the position of the elevating body 11 in this way, the case 14 itself may be rotated with respect to the accommodation hole 5. Alternatively, when the case 14 is constituted by an inner case and an outer case, the position of the elevating body 11 may be adjusted by rotating the inner case with respect to the outer case.

In other words, the sliding door guide device 1 includes the flange member 20 that is fixed to the floor 4 so as to hold the upper end peripheral portion (the bowl-shaped portion) 17 of the case 14 from above and to cover the accommodation hole 5. The suspension door guide device 1 can be firmly attached to the floor 4 where it is difficult to accurately form the accommodation hole 5 of the case 14. That is, for example, in the case where the accommodation hole 5 is formed in the floor 4 made of concrete, the floor 4 made of tile finish, the floor 4 in which a thin floor material is stuck on the concrete base, or the like. It becomes difficult to form with high accuracy. In the present embodiment, since the flange member 20 is provided to be fixed to the floor 4 so as to hold the bowl-shaped portion 17 of the case 14 from above and to cover the accommodation hole 5, the diameter dimension of the accommodation hole 5 is the case. Even in the case where the outer peripheral diameter is formed larger than the outer diameter of the case 14, the case 14 can be firmly fixed by the flange member 20. In addition, it is possible to reduce the necessity of accurately forming the diameter of the accommodation hole 5 so as to be a diameter corresponding to the outer diameter of the case 14.

  In the present embodiment, the elastic member 16 is provided on the bottom of the case 14 so as to be elastically contacted with the inner bottom surface 6 of the receiving hole 5 and press the flanged portion 17 of the case 14 against the lower surface side of the flange member 20. . Accordingly, the case 14 is pressed against the lower surface side of the flange member 20 by the elastic member 16, so that the backlash of the case 14 accommodated in the accommodation hole 5 can be suppressed. Further, even when the inner bottom surface 6 of the accommodation hole 5 is uneven or the depth of the accommodation hole 5 is too deep, the case 14 is pushed upward by the elastic member 16, Since the upper peripheral edge portion (saddle-shaped portion) 17 of the 14 is pressed against the lower surface side of the flange member 20, the case 14 can be stably accommodated.

Moreover, in this embodiment, since the elastic member 16 is fixedly provided in the bottom part of the case 14, handling property and workability can be improved.
Instead of the embodiment in which the elastic member 16 is fixedly provided on the case 14 as described above, the elastic member 16 is separated from the case 14. For example, an adhesive or It may be fixed by an adhesive or the like. Or the elastic member 16 is good also as what is accommodated in the accommodation hole 5 formed in the floor | bed 4 at the time of construction. Further, such an elastic member 20 may not be provided.

  Further, in the present embodiment, the flange portion 17 is provided on the upper end periphery of the case 14, and the lower surface side opening periphery portion 22 of the flange member 20 is in contact with the flange portion 17. Thereby, for example, compared with the case where the flange portion 17 is not provided on the upper end periphery of the case 14, the flange portion 17 is connected to the flange portion 17 while reducing the diameter of the lower portion of the case 14 that houses the lifting body 11. The case 14 can be stably fixed by bringing the lower surface side opening peripheral edge portion 22 of the member 20 into contact.

  Further, in the present embodiment, the flange portion 17 is provided over the entire periphery of the upper end periphery of the case 14, and the lower surface side opening peripheral edge portion 22 of the flange member 20 is applied to the flange portion 17 over the entire periphery.

Can be fixed to.

  Moreover, in this embodiment, the concave step part 22 which receives the upper end peripheral part (saddle-shaped part) 17 of the case 14 is provided in the lower surface side opening peripheral part 22 of the flange member 20 over the perimeter. Therefore, the bowl-shaped portion 17 of the case 14 can be received by the concave stepped portion 22 of the flange member 20, and the movement of the case 14 in the direction of the floor 4 surface area can be restricted. Further, since the concave step portion 22 for receiving the flange portion 17 is provided as described above, the upper surface of the periphery of the opening 21 of the flange member 20 and the case 14 can be secured while the thickness of the flange member 20 can be relatively secured. The step with respect to the upper surface can be reduced.

  In the present embodiment, the flange member 20 is provided with the stopper insertion hole 25 through which the stopper 7 for fixing the flange member 20 to the floor 4 is inserted. The flange member 20 can be firmly fixed to the floor 4 by the tool 7. In addition, without providing such a fastener insertion hole 25, for example, the flange member 20 may be fixed by an adhesive or the like, or a fastener hole is appropriately formed at a construction site or the like. Also good.
