Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dropping device used for a door.

BACKGROUND ART Conventionally, a drop-in device has been commonly used as a means for identifying one side of a double-hung door to the floor or the like for the purpose of performing operations.

However, such a drop-in device has a structure in which an insertion bolt provided on the door body so as to be slidable in the vertical direction is inserted into a recessed receiver formed on the floor surface, etc. As a result, the bottom of the hole in the receiver is aligned upwards, and the insertion bolt is not fully inserted, making it impossible to securely secure the lever, and the receiver cannot function as a drop-in device. This is particularly noticeable in gates that are exposed to wind and rain. However, since the opening of the receiver is narrow, it is difficult to remove dust that has accumulated at the bottom.

The present invention has been made in view of this point, and is such that when the drop-in device is slid downward and the lower end thereof is dropped into the receiving section, the receiving device is inserted into the receiving section. By using a drop-in device that has a mechanism for removing dust accumulated on the holder, when dropping the difference 1 to 1-piece bolt into the receiver part, it is possible to simultaneously remove the dust accumulated in the receiver part, The object of the present invention is to provide a dropping device that eliminates the above-mentioned drawbacks.

The present invention will be described in detail below based on embodiments shown in the drawings.

Figures 1 and 2 show an embodiment of the present invention, in which the lower end of the insertion bolt body 1 is installed in a door body (not shown) so as to be able to slide downward. A bearing 2 is fixedly attached, and a protrusion 3 is formed at the tip of the bearing 2. A drill 4 is fitted with a circumferential groove 5 formed at the rear of the bearing 2, and is pivoted so as to be rotatable in the horizontal direction. has been done. And the door body (
A bearing 8 that fits into the blade groove 7 of the drill 4 is attached to the lower end metal fitting 6 (not shown).

Note that reference numeral 9 indicates a receiver installed on the floor or the like (not shown).

In order to use the dropping device having the configuration shown in this embodiment, the state shown in FIG.
In other words, while the insert bolt body 1 is slid upward and engaged, the engagement of the insert bolt body 1 with the door (not shown) is released, and the insert bolt 1' is moved as shown in FIG. All you have to do is slide the main body 1 downward. When the insert bolt body 1 is slid downward, the drill 4 pivoted to the lower end of the insert bolt body 1 also slides downward, but at the same time, the bearing 8 is fitted into the blade groove 7 of the drill 4. Drill 4
rotates horizontally. Therefore, if dust or the like has accumulated in the receiver part 9, it can be removed by drilling with the drill 4. In particular, in such an embodiment, the protrusion 3 is formed at the tip of the drill 4, so that drilling is easy and sufficient, and for example, at the gate R etc., the deposits are exposed to the wind and solidified. In such cases, -C also has no functional decline. Then, by sliding the insert bolt body 1 again in the -E direction, the drill 4 rotates in the opposite direction and returns to the state shown in FIG. 1, and the door is released from the fixed state.

In addition, FIGS. 3 to 5 show other embodiments of the present invention, and -C in this embodiment represents a door body (not shown).
A pair of protrusions 10 are protruded from the lower end of the insertion bolt body 1 which is attached so as to be slidable in the vertical direction, and a shovel 11 having a substantially width-like shape as a whole is inserted into the lower end fitting 6 near its center. It is pivotally connected to the bolt body 1 by a shaft 12 at an offset position. And the fan-shaped side plates 1 of the shovel 11:
3 has an elongated hole 14 bored in the radial direction, and the above-mentioned protrusion is provided as a plaything in the elongated hole 14.

The method of using the dropping device having the structure shown in this embodiment is to slide the insert bolt body l downward from the state shown in FIG. 4, as in the previous embodiment. At this time, the protrusion 10 protruding from the lower end of the insert bolt body 1 is loosely fitted into the elongated hole 14 formed in the side plates 13 of the shovel 11, so that a connecting effect is produced, and the shovel 11 has a shaft 12. The receiver rotates around the center, and as shown in FIGS. 5 and 6, the receiver protrudes into the portion 9, and the insertion is completed. At this time, the dust accumulated on the receiver section 9 is removed by the rotation of the shovel 11. Then, when the insert bolt body 1 is slid upward again, the threaded bell rotates in the opposite direction and returns to the state -\ shown in FIG. 4.

Since the present invention is constructed as described above, even if dust or the like accumulates on the receiver during use or when not in use, the insertion bolt can be dropped into the receiver in the same way as a conventional dropping device. It has the various effects of a shade, with the ability to remove dust and other particles from the tray simply by pushing it in, and at the same time, it has the function of fixing the door to the floor, similar to a regular drop-in device.
