  When the opening 30 for attachment is formed in the front wall part 33 and the back wall part 34 of the vertical gutter material 3, the rigidity of the vertical gutter material 3 will fall. FIG. 7A shows a horizontal cross-sectional view of a portion where the vertical opening 3 is not formed, and FIG. 7B shows that the vertical opening 3 is formed. The horizontal sectional view of a part is shown. As a decrease in the rigidity of the vertical saddle member 3, a decrease in the bending rigidity around the axis 8 in the front and back direction is particularly problematic. That is, as shown in FIG. 1, the sliding door 1 is pulled in the lateral direction by inserting a finger into the pulling member 4. At this time, a bending moment about the axis 8 in the front and back direction is generated in the vertical saddle member 3 whose upper and lower sides are fixed to the horizontal anchor member 7. Then, the bending of the vertical bar 3 with respect to this bending moment becomes a problem.

In the vertical saddle member 3 of the first embodiment, the front and back directions of the portion where the mounting opening 30 shown in FIG. 7A is not formed and the portion where the mounting opening 30 shown in FIG. 7B is formed. The sectional secondary moment I around the axis 8 and the section modulus Z are shown.

That is, in the first embodiment, as shown in FIG. 4A, the vertical dimension of the reinforcing member 5 is 200 (mm). In particular, the length of the reinforcing member 5 in the vertical direction is preferably as long as possible (for example, 260 (mm)) as long as it fits between the upper and lower fixing portions 44.

  In addition, when the pulling member 4a and the pulling member 4b are each independently attached to the attachment opening 30 of the vertical saddle member 3, the pulling member 4 does not need to be provided with the fixing portion 44. Further, the vertical dimension of the reinforcing member 5 does not have to be within the range that fits between the fixed portions 44, and may be equal to or greater than the vertical length of the attachment opening 30.

  As shown in FIG. 4 (a), screws 55 (see FIG. 1) are fixed to the side plate portion 52 and the side plate portion 53 with a predetermined distance (150 (mm) in the first embodiment) vertically. A screw hole 54 is formed. Further, the inner wall portion 31 and the outer wall portion 32 are formed with insertion holes 38 through which the screws 55 are inserted at positions corresponding to the screw holes 54.

  As shown in FIG. 4A, the reinforcing member 5 is fixed to the vertical gutter member 3 through an attachment opening 30. As shown in FIG. Then, the screw 55 is inserted from the outside into the insertion hole of the inner wall portion 31 and the insertion hole 38 of the outer wall portion 32, and is screwed into the screw hole 54 of the side plate portion 52 and the screw hole of the side plate portion 53. Is fixed to the vertical gutter 3.

As shown in FIG. 1, the closing member 39 is fitted into the recessed portion 37 of the outer wall portion 32 to close the recessed portion 37, and the insertion hole 38 and the screw 55 are hidden.

The cross-sectional secondary moment I around the axis 8 in the front and back direction of the reinforcing member 5 shown in FIG. 7C is about 8200 (mm ⁴ ). The section secondary moment I of the portion where the attachment opening 30 of the vertical member 3 to which the reinforcing member 5 is fixed is not formed is about 52100 (mm ⁴ ), and the section coefficient Z is about 2700 (mm ³ ). Yes. Thereby, it turns out that not only the fall of the bending rigidity of the vertical hook material 3 is suppressed, but the bending rigidity is improved rather than the part in which the opening 30 for attachment of the vertical hook material 3 is not formed.

  In the present invention, by providing the reinforcing member 5, a decrease in the bending rigidity of the vertical rod member 3 is suppressed, and bending (deflection) of the vertical rod member 3 when the sliding door 1 is pulled is suppressed. . Thereby, it becomes easy to open and close the sliding door 1, and the damage of the vertical gutter material 3 by the vertical gutter material 3 bending is suppressed. In particular, it is particularly effective in the vertical rod material 3 having a narrower width than the conventional one.

  The present invention can be applied not only to the sliding door 1 but also to general building tools such as windows, screen doors, rain doors, hinged doors, partitions that can slide along ceiling rails and floor rails.
