Description

[Detailed description of the invention] [Technical field] The present invention is a wooden door in which an electric lock for locking and unlocking the door is installed in the door frame of the wooden door frame. It's about frames.

[Background technology]

Generally, when attaching an electric lock to a door frame, if the door frame is made of wood, the wiring drawn out from the electric lock will be exposed outside the door frame, spoiling the beauty of the door frame. For this reason, the present invention discloses a structure in which a recessed groove for accommodating the wiring is formed in the door stop frame on which the electric lock is attached, and this recessed groove is covered with a cover plate. By the way, the electric lock is provided with a thumb turn for mechanically locking and unlocking the electric lock, and it is required that the electric lock be attached in such a manner that this thumb turn is exposed on the indoor side of the door frame. However, it is possible to treat the door stop stile and the cover plate as one body and have the thumb turn protrude from the surface of the cover plate as in the past, that is, the thumb turn plate provided on the indoor side of the electric lock and the cylinder plate provided on the outdoor side. If an electric lock is installed in such a way that the doorstop stile and cover plate are held together at the same time, the thumb turn plate must be removed when attaching or detaching the cover plate to inspect wiring, etc., which is inconvenient. Another problem is that if the thumb turn protrudes toward the indoor side, clothes or the like can easily be caught on it.

[Purpose of invention]

The present invention was developed in view of the above-mentioned problems, and its main purpose is to independently fix the cover plate and electric lock so that the cover plate can be used as an electric lock. The purpose is to make it easier to inspect and repair wiring, etc. by making it possible to attach and detach it independently, and to make it easier to inspect and repair wiring, etc. Another purpose is to make it so that the thumb turn does not protrude into the room, making it easier to attach clothes to the thumb turn. The purpose is to prevent the thumb turn from being damaged by being hooked or by objects hitting the thumb turn.

[Disclosure of invention]

In this invention, a recessed groove for storing the wiring drawn out from the electric lock is formed in the doorstop frame, a cover plate that covers the groove is detachably attached to the doorstop frame, and the electric lock is attached to the doorstop frame. fixed,
A structure is disclosed in which the thumb turn of the electric lock is housed in a through hole formed in the cover plate in a manner that it does not protrude from the surface of the cover plate, so that the cover plate can be attached and detached independently of the electric lock.

Hereinafter, embodiments of the present invention will be described based on the drawings. A wooden door frame equipped with an electric lock according to the present invention basically has a door frame 1 in a wooden door frame 1.
An electric lock 3 for locking and unlocking the door by electric drive is attached to a door stop frame 2 that serves as a door stop, and a recessed groove 5 in which a wiring 4 drawn out from the electric lock 3 is housed on the interior side of the door stop frame 2. is formed, and the groove 5 is covered by a wooden cover plate 6 which is detachably attached to the indoor surface of the door frame 2, and the electric lock 3 is mechanically applied. A thumb turn 7 for locking protrudes from the indoor side surface of the door frame 2, and the thumb turn 7 is inserted into a through hole 8 formed in the cover plate 6 corresponding to the thumb turn 7 in a manner that does not protrude from the indoor surface of the cover plate 6. It contains 7. In this embodiment, an example is shown in which the doorstop frame 2 is a mullion.

The door frame 1 is made of wood, and a door (not shown) is pivotally attached to one stile (not shown).
A mullion 2 is provided on the doorstop side of the door. mullion 2
The upper end reaches a middle stile 12 installed between both vertical stiles 11 of the door frame 1. Furthermore, an upper rail 13, a middle rail 14, and a lower rail 15 are interposed between the mullion 2 and one of the stiles 11. In the figure, 16 is the upper stile. The mullion 2 has a built-in electric lock 3 that locks and unlocks the door by electric drive, and a mechanical lock and unlocker for the electric lock 3 is installed on the indoor side of the mullion 2 at a position corresponding to the electric lock 3. Thumb turn 7 is attached. As shown in FIGS. 3 to 5, the electric lock 3 is installed in a mounting hole 20 penetrated through the mullion 2. A method in which the opening edge of the mounting hole 20 is sandwiched between a cylinder plate 18 disposed at the tip of the cylinder 19 provided in the mounting hole 20 and a thumb turn plate 17 disposed on the indoor side of the mounting hole 20. It is fixed at vertical position 2. The cylinder plate 18 and the thumb turn plate 17 are connected from the indoor side by a drawing screw 9 that is screwed into a boss 10 formed on the cylinder plate 18 through the thumb turn plate 17. Here, since the length of the drawing screw 9 is slightly shorter than the thickness of the mullion 2, the tightening operation is relatively easy. The electric lock 3 is electrically operated except for being mechanically locked and unlocked by the thumb turn 7 or the cylinder 19, and a wiring 4 for transmitting power and control signals for the electric lock 3 is drawn out. The wiring 4 is housed in a groove 5 formed in the indoor side surface of the mullion 2 so as to run vertically, and is pulled out upward from the electric lock 3. A wooden cover plate 6 covering substantially the entire surface of the mullion 2 is removably attached to the indoor surface of the mullion 2 with a plurality of screws 21. A through hole 8 is formed in the cover plate 6 in correspondence with the thumb turn 7. The through hole 8 is formed in the shape of a mortar whose diameter gradually decreases in the opposite direction from the indoor opening end, and the thumb turn 7 can freely rotate within the through hole 8. The thickness of the cover plate 6 is set to be equal to or slightly larger than the amount of protrusion of the thumb turn 7 from the mullion 2, so that the thumb turn 7 does not protrude outward beyond the indoor surface of the cover plate 6. Further, a notch 26 is formed on the back surface of the cover plate 6, and the thumb turn plate 17 is formed with a cutout 26.
is accommodated in the recess 26, so that the head of the draw screw 9 is covered by the cover plate 6. 27 in the figure is a door stop. A push button mounting hole 22 is formed in the cover plate 6 at a position above the electric lock 3, and an operation push button 23 for locking and unlocking the electric lock 3 is mounted therein. The wiring 4 drawn out from the operation push button 23 is also accommodated in the groove 5. The wiring 4 housed in the groove 5 reaches the upper end of the mullion 2 and is connected to a terminal block 24 housed in the upper frame 13. At the terminal block 24, as shown in FIG. 2, the electric lock 3 and the operation push button 23 are connected, and these are also connected to the power line 25.

The terminal block 24 is housed in a recess 29 provided on the indoor side surface of the upper deck 13, and a cover plate 30 covering almost the entire surface of the upper deck 13 on the indoor side is detachably attached to a wooden screw 31. It is attached with. This prevents the terminal block 24 from being exposed and all the wiring 4 to be concentrated on the terminal block 24, making repairs and inspections easier. A power supply line 25 drawn out from the door frame 1 is supplied with commercial power on which a control signal is superimposed for locking and unlocking the electric lock 3.
The electric lock 3 can be opened and closed even at a location away from the door frame 1. A stainless steel hakama 32 is attached to the lower edge of the door frame 1, and at a portion of the hakama 32 corresponding to the mullion 2, the hakama 32 protrudes toward the indoor side, and a stepped portion 33 formed by the upper end surface of the hakama 32 and the mullion 2 is formed. is formed. The lower end of the cover plate 6 is placed on the stepped portion 33, and the cover plate 6 is attached to the mullion 2 in this state. Therefore, even if the concrete floor surface is higher on the indoor side, the cover plate 6 can be installed with the cover plate 6 floating upwards, and the level difference in the floor surface will not get in the way when the cover plate 6 is attached or removed. It has the advantage of Also, Hakama 32
Since it is made of stainless steel, it will not corrode, and it prevents the wooden door frame 1 from coming into direct contact with the concrete floor surface, which easily absorbs moisture, and prevents the wooden door frame 1 from corroding due to moisture. prevent this from happening.

[Summary of the idea]

As described above, in the present invention, the thumb turn of the electric lock is housed in the through hole drilled in the cover plate in a manner that it does not protrude beyond the indoor surface of the cover plate, so that it is possible to hang clothes on the thumb turn. This has the advantage that damage to the thumb turn caused by hitting the thumb turn with an object can be prevented. In addition, since the electric lock is fixed to the door frame separately from the cover plate, when the cover plate is attached or removed, only the cover plate can be attached or removed from the door frame independently of the electric lock, making it easier to inspect wiring etc. It is something. Furthermore, as shown in the embodiment, when the electric lock is mounted with a mullion sandwiched between the cylinder plate and the thumbturn plate, the length of the drawing screw can be made relatively short; This facilitates handling when tightening the draw screw.
