2. Description of the Related Art A dropping device for a French drop according to the present invention is provided at the upper end of a rod which can be raised and lowered at both upper and lower ends of a child door of a parent door used as an entrance door or the like. It is for receiving a rod.

[0002]

2. Description of the Related Art As a front door, a parent-child door as shown in FIG. 15 has been widely known. The parent-child door is constructed by installing a parent door 6 and a child door 7 inside a door frame 5 surrounded by upper and lower horizontal frames 1 and 2 and left and right vertical frames 3 and 4. Of these, the parent door 6 is swingable on one vertical frame 4 (right side in FIG. 15) and the child door 7 is swingable on the other vertical frame 3 (left side in FIG. 15) by hinges 8 and 8, respectively. I support it.

In the case of such a parent-child door, the parent door 6 is normally used.
By opening and closing only, you can enter and exit from the entrance.
On the other hand, the child door 7 is opened only when it is necessary to widen the opening width of the entrance, such as when putting in and out a large luggage. For this reason, locking devices generally called French droppers are provided at both upper and lower ends of the child door 7 so that the child door 7 is not opened in normal times.

The French dropper comprises a vertically movable rod provided on the child door 7 side and a receiving hole provided on the horizontal frames 1 and 2. That is, as shown in FIGS. 16 and 17, a part of the horizontal frame 2 is provided with a receiving hole at a position facing the lower end of the French drop rod 9 provided on the child door 7 with the child door 7 closed. 1
0 is provided. The receiving hole 10 is formed by screwing and fixing a receiving member 12 as shown in FIGS. 19 to 21 inside a through hole 11 formed in the horizontal frame 2 as shown in FIG.

[0005] With the child door 7 closed, the rod 9 is lowered (in the case of dropping France provided at the lower end of the child door 7; it is raised when it is provided at the upper end). If it is made to enter the inside of the above-mentioned receiving device 12, the above-mentioned child door 7
Will not swing about the hinges 8,8.
In addition, the inconvenience of the child door 7 opening and closing when the parent door 6 opens and closes is eliminated.

[0006]

However, in the case of the conventional French drop receiving device configured as described above, in order to absorb an assembling error of the child door 7 inside the door frame 5, etc.
The width W of the receiving recess 13 of the receiving tool 12 is larger than the outer diameter D of the rod 9 (W> D). For this reason, even when the child door 7 is closed and locked, it is inevitable that the child door 7 slightly swings about the hinges 8 and 8. If the child door 7 swings slightly when opening and closing the main door 6, it is not preferable because the opening and closing operation of the main door 6 cannot be performed smoothly.

In order to prevent the child door 7 from swinging due to the above-mentioned causes, an adjusting piece is provided at one end in the width direction of the receiving recess 13 so as to be adjustable in position in the width direction. It is conceivable to adjust the width dimension of a portion of the receiving recess 13 into which the rod 9 can be inserted by using a piece. The operation of providing such an adjusting piece at the opening of the receiving recess 13 can be performed without trouble for the lower horizontal frame 2 without particularly devising the structure. That is, in a state where the adjustment piece is placed on the upper surface of the lower horizontal frame 2, the screw into which the adjustment piece is inserted from above is inserted into the horizontal frame 2.
By screwing into the screw hole provided on the side and further tightening, the work of fixing the adjusting piece can be performed. However, regarding the upper horizontal frame 1, the receiving recess 13 is opened downward, and it is necessary to screw a screw for fixing the adjustment piece to the horizontal frame 1 from below. It is necessary to devise a structure in order to carry out efficiently. In other words, the fixing work of tightening the screws while suppressing the adjustment pieces attached to the lower surface of the upper horizontal frame 1 from dropping is troublesome. For this reason, it is desired to realize a structure that does not need to consider the prevention of the adjustment piece from falling when the screw is tightened. The French drop receiving device of the present invention was devised in view of such circumstances.

[0008]

According to the present invention, there is provided a receiving device for dropping a french, which is formed in a part of the upper horizontal frame at a position where an upper end portion of a rod forming the french drop is opposed to the rod. It has a through hole that forms a hole, an adjusting piece mounted inside the through hole, and a screw for supporting and fixing the adjusting piece inside the through hole. The through holes are
The rod includes a receiving hole having a width larger than the outer diameter of the rod, and a notch formed at one end of the receiving hole in the width direction to allow the screw to pass therethrough. . The adjusting piece is formed by combining a main body and a nut. Of these, the main body holds a groove that allows portions existing on both sides of the cutout portion in a part of the horizontal frame to enter, and a nut that is provided at an intermediate portion in the thickness direction and that is screwed with the screw. A holder is provided, and a circular hole is provided for communicating the holder with the upper and lower surfaces of the main body. And the adjusting piece is a nut and the notch held in the holding portion of the main body in a state in which portions existing on both sides of the notch in a part of the horizontal frame enter the inside of the groove. By screwing and tightening the screw that inserted the circular hole, inside the above-mentioned through hole,
It is mounted so that a part of the through hole near one edge in the width direction is closed.

[0009]

In the case of the receiving device of the present invention constructed as described above, the adjusting piece is displaced in the width direction of the receiving hole at one side edge of the receiving hole, so that the adjusting piece and the adjusting piece are displaced. If the adjusting piece is fixed to the horizontal frame by adjusting the distance between the other side edge of the receiving hole and the screw, the rod will not rattle inside the receiving hole. Also, while fixing the adjustment piece to the receiving hole, after allowing the portions existing on both sides of the cutout part to enter inside the groove formed in this adjustment piece, a part of the horizontal frame,
Even if the user releases his / her hand from the adjusting piece, the adjusting piece does not fall. Therefore, when the screw is screwed into the nut and the work is further tightened, it is not necessary to add a hand to the adjusting piece in order to prevent the adjusting piece from dropping.
