Description

The present invention relates to a door.

Conventionally, doors incorporating electric locks in the upper part and the lower part of the handle have been known (see Non-Patent Document 1). Such doors are usually locked and unlocked by operating the buttons on the remote control, but in the event of a power outage due to a disaster such as an earthquake or fire, the cover covering the electric lock is removed and the electric lock is provided. You can lock and unlock by inserting the key into the keyhole.
In this way, conventional doors are troublesome because the cover must be removed and then the key must be inserted in the event of a power failure, and the cover must be tied to the pedestal of the handle so that the removed cover is not lost. Therefore, the cost was increasing.

(A) is a front view of the cover, (b) is the same plan view, (c) is the same side view, (d) is the same rear view, and (e) is a sectional view taken along the line AA.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show an embodiment of the door of the present invention. This door is a front door, and as shown in FIG. 4, it is attached to a door frame (not shown) installed at the opening of the skeleton so as to open to the outside by a hinge 9. An outdoor side handle 1 and an indoor side handle 10 are attached to the outdoor side surface and the indoor side surface on the door end side of the door, respectively.

As shown in FIG. 3, the outdoor handle 1 includes an upper and lower pedestals 3, 3 and a handle 4 attached across the upper and lower pedestals 3, 3 and an upper portion of the upper pedestal 3 and a lower portion of the lower pedestal 3. It has covers 5 and 5 attached to each of them, and has a vertically symmetrical arch shape.
The indoor handle 10 has upper and lower pedestals 11 and 11 and a straight rod-shaped handle 12 attached across the upper and lower pedestals 11 and 11.

This door can be attached to the upper position and the lower position of the outdoor handle 1 by selecting either the manual lock 13 or the electric lock 14.
FIG. 1 shows a case where the manual lock 13 is attached. The manual lock 13 has a lock case 15a attached to the inside of the door, a cylinder 2a attached to the outdoor side, and a thumb turn 16a attached to the indoor side.
The lock case 15a includes a dead bolt (not shown) that appears and disappears from the door end of the door, and a drive mechanism that drives the dead bolt.
The cylinder 2a moves the drive mechanism in the lock case 15a by inserting the key 18 into the keyhole 17 (see FIG. 3) and turning it so that the dead bolt appears and disappears. As shown in FIG. 1, the cylinder 2a has a cylindrical shape in which a portion protruding to the outdoor side of the door is reduced in diameter toward the front side. A phosphorescent portion 19 (see FIG. 3) is provided around the keyhole 17, which makes it easy to insert the key 18 into the keyhole 17 even when it is dark.
The thumb turn 16a moves the drive mechanism in the lock case 15a by turning the knob 20 with a finger to make the dead bolt appear and disappear.

The pedestal 3 of the outdoor handle 1 is made of resin, and as shown in FIG. 1, has cylinder peep holes 6 through which the cylinder 2a can be seen in the upper part of the upper pedestal 3 and the lower part of the lower pedestal 3. There is.
The cover 5 is also made of resin and is attached to the outdoor side of the upper part of the upper pedestal 3 and the lower part of the lower pedestal 3 as shown in FIG. The cover 5 is inclined so that the front surface 7 is continuous with the front surface 21 of the handle 4. As shown in FIGS. 1 and 5, the cover 5 is formed with a key insertion hole 8 for inserting the key 18, and the key insertion hole 8 has a mortar shape whose diameter increases toward the front side. The bottom diameter d of the key insertion hole 8 is smaller than the diameter D of the front end of the cylinder 2a, and the front surface 7 of the cover 5 is inclined. Therefore, the upper cover 5 is used for key insertion. The inner peripheral surface of the hole 8 extends forward on the lower side as compared with the upper side, and the opening of the key insertion hole 8 can be seen from above (see FIG. 5B). The inner peripheral surface of No. 8 extends forward on the upper side as compared with the lower side, and the opening of the key insertion hole 8 can be seen from below. Further, the cover 5 has claws 22 protruding toward the indoor side at the upper part (lower part in the lower cover) and the left and right side portions, and these claws 22 are locked to the pedestal 3 from the outdoor side. Then, it can be detachably attached to the pedestal 3.

FIG. 2 shows a case where the electric lock 14 is attached. The electric lock 14 has a lock case 15b attached to the inside of the door, a cylinder 2b attached to the outdoor side, and a thumb turn 16b attached to the indoor side.
The lock case 15b is provided with a dead bolt (not shown) that appears and disappears from the door end, an electromagnetic drive mechanism that drives the dead bolt, and a mechanical drive mechanism, and is electromagnetically operated by operating a button on a remote controller (not shown). The drive mechanism operates, and the dead bolt can be moved in and out.
The cylinder 2b moves the mechanical drive mechanism in the lock case 15b by inserting the key 18 into the keyhole 17 (see FIG. 3) and turning it in the event of a power failure, so that the dead bolt appears and disappears. Similar to the cylinder 2a in the case of the manual lock 13, the cylinder 2b has a cylindrical shape in which the portion protruding to the outdoor side of the door is reduced in diameter toward the front side, as shown in FIG. A phosphorescent portion 19 (see FIG. 3) is provided around the keyhole 17, which makes it easy to insert the key 18 into the keyhole 17 even when it is dark.
The thumb turn 16b moves the mechanical drive mechanism in the lock case 15b by turning the knob 20 with a finger to make the dead bolt appear and disappear.

As shown in FIGS. 1 and 2, this door has pedestals 3 and 3 of the outdoor handle 1 and handles 4 and covers 5 and 5 depending on whether the manual lock 13 is attached or the electric lock 14 is attached. It is also used for both purposes, so that the design is unified between the case where the manual lock 13 is attached and the case where the electric lock 14 is attached. As shown in FIG. 2, even when the electric lock 14 is attached, the cover 5 is formed with a key insertion hole 8 for inserting the key 18, so that the cylinder 2b can be used without removing the cover 5 even in the event of a power failure. The key 18 can be inserted into the keyhole 17 of the above to perform the locking / unlocking operation. In the cover 5, the diameter d at the bottom of the key insertion hole 8 is smaller than the diameter D at the front end of the cylinder 2b.

As described above, the door includes a handle (outdoor handle) 1 and cylinders 2a and 2b, the handle 1 has pedestals 3 and 3, handles 4 and covers 5 and 5, and the pedestal 3 has. , Cylinders 2a and 2b have a peep hole 6 for a cylinder, a cover 5 is attached to a pedestal 3, a front surface 7 is continuous with a front surface 21 of a handle 4, and a key for inserting a key 18 is inserted. Since the hole 8 is provided and the diameter d at the bottom of the key insertion hole 8 is smaller than the diameter D at the front end of the cylinders 2a and 2b, it is not necessary to remove the cover 5, and the key 18 can be attached to the cylinders 2a and 2b. When the key 18 is inserted into the key hole 17, the tip of the key 18 does not hit the corners of the front ends of the cylinders 2a and 2b, and the key 18 can be smoothly inserted into the key hole 17, so that the operability of the locking / unlocking operation is excellent. Further, since the cover 5 does not need to be removed, it is not necessary to connect it to the pedestal 3 with a string, and the cover 5 can be used for both the electric lock 14 and the manual lock 13, so that the cost can be reduced. Can be done.
The front surface 7 of the cover 5 is inclined, and the key insertion hole 8 for inserting the key 18 has a mortar shape that expands in diameter toward the front, so that the key hole 17 can be easily seen. It becomes easier to insert the key 18 into the 17.

The present invention is not limited to the embodiments described above. The specific shape and material of the pedestal, handle and cover can be changed as appropriate. In the embodiment, the handle is shared between the case where the manual lock is attached and the case where the electric lock is attached, but only the manual lock or the electric lock may be attached. The structure of the door itself is arbitrary.
