[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
In this description, “front” refers to the front side of FIG. 1, “back” refers to the back side, “left” refers to the left side of FIG. 1, and “right” refers to the right side of FIG.
[0007]
The sliding door frame 1 is transferred to a pair of left and right vertical frame members 3 and mutually opposing surfaces (the lower right surface of the left vertical frame member 3 and the lower left surface of the right vertical frame member 3) at the lower ends of the vertical frame members 3. The sill 4 is provided, and the duck 5 passed to the mutually opposing surfaces at the upper end of the vertical frame member 3. A pair of front and rear sliding doors (not shown) is guided in a left-right movable manner by a pair of front and rear sliding door guide grooves (not shown) of the sill 4 and a pair of front and rear sliding door guide grooves 9 (see FIG. 3) of the Kamoi 5. .
[0008]
A door punching groove 11 for fitting the end portion of the closed sliding door is formed in the vertical frame member 3 over the entire length.
[0009]
As shown in FIGS. 2 and 3, a pair of front and rear female screw cylinders 13 is provided at the right end of the Kamoi 5. The female screw cylinder 13 is formed with a screw hole 13a whose axis is directed in the left-right direction.
[0010]
The right end of the front female screw cylinder 13 is fitted into a screw insertion hole 14 that protrudes into the door-skin groove 11 and penetrates in the left-right direction formed in the vertical frame member 3. On the other hand, the right end portion of the rear female screw cylinder 13 is fitted in the screw insertion hole 14. In short, the right vertical frame member 3 has the above-described configuration because the door scraping groove 11 is formed only on the front side.
[0011]
A screw 15 is screwed into the female screw cylinder 13 from the outside of the vertical frame member 3 through a screw insertion hole 14. With such a configuration, the upper portion of the right vertical frame member 3 and the right end portion of the Kamoi 5 are connected.
[0012]
A closing member 19 is fitted in a gap 18 formed by the end surface of the head 5 and the inner peripheral surface of the door-skin groove 11. The closing member 19 has a female screw cylinder holding piece 20 having a pair of front and rear elasticity with a predetermined interval in the front-rear direction at the front part. Further, when the closing member 19 is rotated 180 degrees in the vertical direction so as to replace the front and rear, or when rotated 180 degrees in the horizontal direction so as to replace the front and rear, the closing member 19 performs the same function as the female screw cylinder holding piece 20. A pair of elastic female screw cylinder holding pieces 21 is provided at the rear part. As is apparent from FIG. 3, the rear side of the female screw cylinder holding piece 20 and the front side of the female screw cylinder holding piece 21 are connected to each other. The internal thread cylinder holding pieces 20 and 21 are formed with claws 22 that prevent the internal thread cylinder 13 from being detached after the internal thread cylinder 13 is held. That is, the pair of front and rear claws 22 facing each other with a gap slightly shorter than the diameter of the female screw cylinder 13 is positioned between the female screw cylinder 13 and then the female screw cylinder 13 is placed between the claws 22 on the closing member 19. When a force of a predetermined value or more in the passing direction is applied, it passes through the female screw cylinder 13 and then returns to its original state by the elasticity of itself and the female screw cylinder holding pieces 20, 21. The holding pieces 20 and 21 are prevented from coming off.
[0013]
The closing member 19 includes a vertical plate-shaped main body 19a and an edge rib 19a, but may be a simple plate. Further, the front-rear width of the closing member 19 is equal to the front-rear width of the door punching groove 11, the thickness in the left-right direction of the closing member 19 is equal to the depth of the door punching groove 11, and the height of the closing member 19 (the female screw cylinder holding). The overall height including the holding piece 20 is equal to the height between the upper surface of the sliding door guide groove 9 and the upper surface of the duck 5.
[0014]
After fitting the closing member 19 into the door-skin groove 11 of the vertical frame member 3 so that the front and rear female screw cylinder holding pieces 20 are opposed to the front female screw cylinder 13, Thus, the closing member 19 can be inserted and fixed in the gap 18 by moving to the female screw cylinder 13 side and holding the female screw cylinder 13 by the female screw cylinder holding piece 20.
In addition, after attaching the closing member 19 to the female screw cylinder 13 using the female screw cylinder holding piece 20, the vertical frame member 3 and the head 5 are abutted, and then the screw 15 is screwed into the female screw cylinder 13. It is clarified that this is the principle of assembly work.
[0015]
Since the connection structure between the left part of the head 5 and the left vertical frame member 3 is the same as that of the right part of the head 5 and the right vertical member 3, the illustration is omitted. Needless to say, the left vertical frame member 3 has a door punching groove 11 at the rear.
[0016]
4 and 5 show a connection state between the right portion of the sill 4 and the right vertical frame member 3. Since the structure is clear from FIG. 4 and FIG. 5, detailed description is omitted.
[0017]
Since the connection structure between the left part of the sill 4 and the left vertical frame member 3 is the same as that of the right part of the sill 4 and the right vertical frame member 3, the illustration is omitted.
