Description

This utility model relates to a door opening tool used when a door handle, latch or front case (case in which a latch is stored) of a Western-style hinged door breaks down or is damaged.

When the door handle or front case or latch of a Western-style hinged door breaks or breaks, if the door of the room where the Western-style hinged door is installed is one Western-style hinged door, it will be confined in the room, and if there are multiple doors in the room, Although it is not confined, there arises a disadvantage that the hinged door cannot be used.

In order to solve such a problem, Patent Document 1 describes a technique in which a door handle for a Western-style hinged door, a latch, or a door opener to be used when a front case or a latch fails or is damaged is incorporated in the front case in advance. Yes. Since the opening device described in Patent Document 1 incorporates a door opening device in the front case in advance, the door can be easily opened when the door handle of the Western-style hinged door or the front case or the latch breaks down or is damaged. .

However, the method of incorporating the door opening device in the front case in advance has the disadvantage that the structure is complicated and expensive. In addition, in the existing Western type door that does not include the door opening device, the front case, latch, It is necessary to update many mechanisms including, and there is a disadvantage that it becomes more expensive. In addition, there is a drawback in that there is a risk of erroneous operation of the opening device incorporated during normal door opening and closing.

Embodiments for carrying out the present invention will be described below with reference to the drawings. 1 and 2 are a side view and a front view, respectively, of Embodiment 1 of the present invention.

As shown in FIGS. 1 and 2, the first embodiment of the present invention includes a first support portion 1 made of a cylindrical rod-like rigid body material having a diameter of 3 mm or less, and a diameter of 3 mm or less at one end of the first support portion 1. The first opening function part A2 and the first opening function part A2 are provided with a cylindrical rod-like rigid body material having a length of 5 mm to 20 mm and an angle of 85 to 95 degrees with the first support part. A cylindrical rod-like rigid body material having a diameter of 3 mm or less at the end opposite to the support part, and having a length of 20 to 30 mm, the first opening function part within a plane including the first support part and the first opening function part A2 A first opening function part B3 installed so as to be within a range of an angle of 85 degrees to 95 degrees with A2, and a first opening function part 6 including the first opening function part A2 and the first opening function part B3. Yes. 1 and 2, the first support part 1 has a cross section larger than the diameter of the first support part 1 installed at the end opposite to the first opening function part 6 and is fixed to the first support part 1. The grip part 4 is provided. The grip part 4 bends a part of the end opposite to the first opening function part 6 of the first support part 1, inserts the grip part into the end part of the first support part 1 like the grip fixing part 5. If the grip part 4 is fixed by bending and the grip part 4 is rotated, the first support part 1 and the first opening function part 6 are also rotated. Although the grip fixing portion 5 is provided here, other methods such as a method of bonding the grip portion 4 to the first support portion 1 with an adhesive may be used, or the grip portion 4 may not be provided.

On the other hand, generally, a Western type door, a latch, etc. are as shown in the structural diagram of the doorknob / latch shown in FIG. In FIG. 5, the door knob 15 is installed on the door 21. By rotating the door knob 15, the shaft 14 rotates, the latch case inner ring 13 portion rotates, and the latch case inner cam 12 moves to the latch case inner ring 13 portion. The latch case cam 12, the latch spring 11, and the latch 10 are pulled toward the door 21, and the latch 10 is stored in the door 21. When the door knob 15 is released, the door knob 15 returns to the original state by the action of the lever handle spring 16, the latch spring 11 pushes the latch 10, fits in the latch receiver 18, and the door 21 is closed. Further, as shown in FIG. 5, the door frame 19 is provided with a door door stop 20, and the door 21 is prevented from further rotating by the door door contact 20.

Since the door door stopper 20 is installed in this way, as an embodiment of the present invention, when the door opening tool is operated from the door door stopper 20 side, the door opening tool is operated from the opposite side of the door door stopper 20. When the door opening tool is used, a difference occurs in the door opening tool, and the first embodiment shown in FIGS.

  FIG. 6 is a diagram showing a usage example of the first embodiment showing a method of opening the door using the door opening tool of the first embodiment shown in FIGS.

In the door opening tool of the first embodiment, the first opening function part (consisting of the first function part A and the first function part B) is inserted into the gap between the door 21 and the door door contact 20 in FIG. The one support portion 1 is rotated so as to be nearly perpendicular to the door 21, and the first opening function portion B3 is brought into contact with the latch 10. If the first support part 1 is moved in the direction of the door knob 15 while the first opening function part B3 is in contact with the latch 10, the latch 10 comes out of the latch receiver 18 and the door can be opened.

As described above, the door opening device according to the first embodiment has the first opening function portion that is bent at a substantially right angle in one plane, so that even if there is a door door stop 20, it acts on the latch 10 to open the door. can do. Unlike the case where the latch is locked, the latch portion can be moved with a small force and can be easily opened with the door opening tool of the first embodiment.

3 and 4 are a side view and a front view, respectively, of the second embodiment of the present invention.
As shown in FIGS. 3 and 4, the second embodiment of the present invention includes a second support portion made of a cylindrical rod-like rigid body material having a diameter of 3 mm or less, and a cylinder having a diameter of 3 mm or less at one end of the second support portion. Although it has a second S-shaped opening function portion in which two arcs having a radius of 5 mm to 8 mm and an arc length of 8 mm to 10 mm are combined in an S shape with a rod-like rigid body material, it is not necessarily an S shape. However, a grip may be provided.

The second embodiment shown in FIGS. 3 and 4 is a door opening tool that is operated from the opposite side of the door door 20. FIG. 7 is a diagram showing a usage example of the second embodiment showing a method of opening the door using the door opening tool of the second embodiment shown in FIGS.

In the door opening tool of the second embodiment, the second opening S-shaped function part 8 is inserted into the gap on the opposite side of the door stop 20 of the door 21 and the door frame 19 of FIG. The second S-shaped opening function unit 8 is brought into contact with the latch 10 so as to be perpendicular to the door frame 19. When the second support portion 7 is moved forward while the second opening S-shaped function portion is in contact with the latch 10, the latch 10 comes out of the latch receiver 18, and the door can be opened.

As described above, the door opening device of the second embodiment has the second S-shaped opening function portion that is bent substantially at right angles within one plane, so that the failure of the latch occurs from the opposite side of the door contact 20 of the door 21 and the door frame 19. Unlike when the door is locked, the latch portion can be moved with a small force and can be opened with the door opening tool of the second embodiment.
