Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The French drop hole device according to the present invention receives rods that can be raised and lowered at both upper and lower ends of a child door among parent and child doors used as entrance doors and the like.

[0002]

[Prior Art]

 Conventionally, a parent-child door as shown in FIG. 15 is widely known as an entrance door. This parent-child door is constructed by building 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 main door 6 is swingable on one (right side in FIG. 15) vertical frame 4 and the child door 7 is on the other (left side in FIG. 15) vertical frame 3 by hinges 8 and 8, respectively. It is supported.

In the case of such a parent-child door, when only the parent door 6 is normally opened / closed, the entrance / exit can be carried out, and when a large luggage is put in / out, it is necessary to widen the opening width of the entrance. Only, the child door 7 is opened. For this reason, a locking device generally called a French drop is provided at both upper and lower ends of the child door 7 so that the child door 7 is not normally opened.

The French dropper is composed of a vertically movable rod provided on the child door 7 side and receiving holes provided on the horizontal frames 1 and 2. That is, as shown in FIGS. 16 to 17, a part of the horizontal frame 2 is located 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. 10 is provided. The receiving hole 10 is constructed by screwing and fixing a receiving tool 12 as shown in FIGS. 19 to 21 inside a through hole 11 formed in the horizontal frame 2 as shown in FIG.

The lower end of the rod 9 is lowered by lowering the rod 9 with the child door 7 closed (when dropping the flange provided at the lower end of the child door 7; ascending when provided at the upper end). If the portion is inserted into the inside of the receiving member 12, the child door 7 will not swing around the hinges 8 and 8, and the child door 7 will open and close when the parent door 6 is opened and closed. Disappears.

[0006]

[Problems to be solved by the device]

 However, in the case of the conventional French hole receiving device configured as described above, the width dimension of the receiving recess 13 of the receiving tool 12 is absorbed in order to absorb the assembling error of the child door 7 inside the door frame 5. W was larger than the outer diameter dimension D of the rod 9 (W> D). Therefore, even when the child door 7 is closed and locked, it is inevitable that the child door 7 slightly swings around the hinges 8 and 8.

If the child door 7 swings slightly when the parent door 6 is opened and closed, the operation of opening and closing the parent door 6 cannot be performed smoothly, which is not preferable.

The French drop hole device of the present invention was devised in view of such circumstances.

[0009]

[Means for Solving the Problems]

 The receiving device of the French dropping device of the present invention has a width dimension larger than the outer diameter of the lifting rod constituting the French dropping device, and the receiving hole formed in the horizontal frame and the one side edge in the width direction of the receiving hole. , An adjusting piece mounted displaceably in the width direction, and a screw for fixing the adjusting piece to the lateral frame.

[0010]

[Action]

 In the case of the French dropping hole device of the present invention configured as described above, the adjusting piece and the receiving hole are moved by displacing the adjusting piece in the width direction of the receiving hole at one side edge of the receiving hole. If the adjusting piece is fixed to the horizontal frame by tightening the screw after adjusting the distance from the other side edge, the rod will not rattle inside the receiving hole.

[0011]

【Example】

 1 to 5 show a hole receiving device provided in a lower horizontal frame 2 as a first embodiment of the present invention. As in the conventional case described above, the horizontal frame 2 is formed with a through hole 11 as shown in FIG. 18, and inside the through hole 11, a receiving device as shown in FIGS. 12 is fixed with screws. The width W of the receiving recess 13 that forms the receiving hole that is formed in the receiving member 12 and that receives the lower end of the rod 9 that forms the drop of France is larger than the outer diameter D of the rod 9. The same as in the case of the conventional structure described above.

Further, in the hole receiving device of the present invention, the adjusting piece 14 made of synthetic resin is screwed and fixed to the upper surface of the receiving recess 13. The adjusting piece 14 has a U-shape as a whole by connecting one ends of the pair of left and right supporting portions 15 and 15 with the adjusting portion 16 so that the central portion of each of the supporting portions 15 and 15 is The elongated holes 17, 17 are formed to be long in the width direction of the receiving recess 13.

The adjustment piece 14 as described above includes the screws 19, 19 which are inserted through the elongated holes 17, 17 and the circular holes 18, 18 (see FIGS. 19 to 20) at both ends of the receiving member 12 and the horizontal frame 2. It is supported on the upper surface of the horizontal frame 2 by being screwed into the circular holes 32, 32 (see FIG. 18) formed in the. With the adjustment piece 14 thus supported on the upper surface of the horizontal frame 2, the adjustment portion 16 of the adjustment piece 14 has a widthwise one side edge portion (the lower edge portion in FIG. It is located on the left side edge in FIG.

Since the French drop receiving device of the present invention is constructed as described above, the adjusting portion 16 is provided at one side edge of the receiving recess 13 in the width direction of the receiving recess 13 (upper and lower sides in FIG. 1). Direction, the horizontal direction in FIG. 2), it is possible to prevent the rod 9 from rattling inside the receiving recess 13.

That is, with the pair of screws 19 and 19 loosened, the adjustment piece 14 is adjusted so that the width of the receiving recess 13 is within the range in which the screws 19 and 19 can be displaced inside the elongated holes 17 and 17. By displacing in the direction, the distance d between the inner edge 16a of the adjusting portion 16 and the other edge of the receiving recess 13 (the upper edge of FIG. 1, the right edge of FIG. 2) can be adjusted.

Therefore, after adjusting the distance d to such an extent that the rod 9 does not rattle, the screws 19 and 19 are tightened, and the adjusting piece 14 is fixed to the horizontal frame 2 together with the receiving tool 12. Thus, the rod 9 will not rattle inside the receiving recess 13.

It should be noted that in order to prevent the position of the adjusting piece 14 from being displaced after the adjustment, the lower surface of the adjusting piece 14 and the upper surface of the receiving member 12 are formed with fine irregularities which can be engaged with each other, or Can also be coated with adhesive on both sides.

Next, FIGS. 6 to 14 show a hole receiving device provided in the upper horizontal frame 1 as a second embodiment of the present invention. A receiving hole for receiving the rod 9 is formed in a part of the horizontal frame 1 at a position where the upper end of the French drop rod 9 provided at the upper end of the child door 7 faces when the child door 7 is closed. Therefore, the through hole 20 as shown in FIG. 8 is formed. The through hole 20, into which the rod 9 can freely enter, has a receiving hole portion 21 having a width dimension W larger than the outer diameter dimension D of the rod 9 and a screw 2 for supporting and fixing an adjusting piece 22 described below. 3 and a U-shaped notch 24 that can be inserted therethrough.

The adjustment piece 22 for preventing the rod 9 from rattling inside the receiving hole portion 21 is composed of a main body 25 as shown in FIGS. 9 to 12 and a nut 26 as shown in FIGS. 13 to 14. Then, the nut 26 is assembled in the holding portion 27 of the main body 25. The holding portion 27 and the upper and lower surfaces of the main body 25 are communicated with each other by circular holes 30 and 30, respectively, so that the screw 23 can be screwed into the nut 26. Further, in the groove portion 28 of the main body 25, portions 29, 29 existing on both sides of the cutout portion 24, which are a part of the lateral frame 1, can enter. That is, the height dimension T of the groove portion 28 is larger than the thickness dimension t of a portion of the lateral frame 1 where the through hole 20 is formed (T> t).

When the adjusting piece 22 configured as described above is attached to the horizontal frame 1, first, the screw 23 is screwed into the nut 26 fitted in the holding portion 27 from the lower side of the main body 25. The distance L between the upper surface of the head 31 of the screw 23 and the lower surface of the main body 25 is slightly larger than the thickness dimension t of the horizontal frame 1 (L> t) (shown by a chain line in FIG. 7). Then, the screw 23 is inserted into the cutout portion 24 of the through hole 20.

In this state (the state in which the screw 23 is not tightened), the adjustment piece 22 is displaceable in the width direction of the through hole 20 (vertical direction in FIG. 6, horizontal direction in FIGS. 7 to 8). Therefore, by displacing the adjusting piece 22 in the width direction, the distance d ′ (FIG. 6) between the side surface of the adjusting piece 22 and the end edge of the receiving hole portion 21 is adjusted so that the rod 9 does not rattle. Then, the screw 23 is tightened, and the portions 29, 29 are strongly sandwiched between the upper surface of the head 31 of the screw 23 and the lower surface of the main body 25. As a result, the adjusting piece 22 is fixed to the horizontal frame 1, and the rod 9 is prevented from rattling inside the receiving hole portion 21.
