Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a wooden door frame in which an electric lock for locking and unlocking the door is mounted inside the door frame which serves as the door stop. be.

[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. However, it is necessary to position the cover plate when attaching and detaching the cover plate to the door frame for inspection or repair of wiring.

[Purpose of invention]

The present invention has been devised in view of the above points, and its main purpose is to facilitate the positioning of the cover plate attachment position.

[Disclosure of invention]

In the present invention, a push button hole that matches the cross-sectional shape of the push button is formed in the cover plate in correspondence with the push button for unlocking the electric lock that protrudes from the fixed position of the door stop frame,
A structure is disclosed in which the attachment position of the cover plate to the door frame is determined by inserting a push button into the push button hole.

Embodiments of the present invention will be described below 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 electrical drive is attached to a door frame 2 which serves as a door stop, and a groove 4 in which the wiring drawn out from the electric lock 3 is housed is provided on the interior side of the door frame 2. The groove 4 is covered by a wooden cover plate 5 which is formed and detachably attached to the indoor surface of the door frame 2. The push button 6 for unlocking the lock 3 protrudes, and the cover plate 5
A push button hole 7 having a cross-sectional shape substantially equal to the push button 6 is formed in correspondence with the push button 6, and by inserting the push button 6 into the push button hole 7, the cover plate 5 can be positioned with respect to the door stop frame 2. It is what is done.
This embodiment shows an example in which the door stop frame 2 is mullioned.

The door frame 1 is made of wood, and a door (not shown) is pivotally attached to one stile (not shown).
As shown in Figure 1, there are two mullions on the door stop side.
is provided. The upper end of the mullion 2 reaches a middle stile 12 installed between both vertical stiles 11 of the door frame 1. Also, mullion 2
Between the stile 11 on one side and the upper stile 13, the middle stile 1
4. The lower deck 15 is installed. 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. The thumb turn 20 to be performed is attached. The electric lock 3 is operated electrically except for mechanically locking and unlocking with the thumb turn 20, and a power source for the electric lock 3 and wiring (not shown) for sending control signals are drawn out. The wiring is carried out in a groove 4 formed to run vertically on the indoor side of mullion 2.
and is pulled out upward from the electric lock 3. A wooden cover plate 5 covering substantially the entire surface of the mullion 2 is removably attached to the indoor surface of the mullion 2 with a plurality of wood screws 21. Further, a through hole 19 is formed in the cover plate 5 in correspondence with the thumb turn 20. A push button 6 for unlocking the electric lock 3 is fixed to the mullion 2 on the indoor side at a position above the electric lock 3.
As shown in FIG. 2, this push button 6 is provided on the outdoor side of the mullion 2, and when a code number is input, the electric lock 3 is activated.
It is linked to a switch (not shown) built into the numeric keypad unit 18 that unlocks the door. Corresponding to the push button 6, a push button hole 7 that matches the cross-sectional shape of the push button 6 is provided through the cover plate 5. However, if the cover plate 5 is attached to the mullion 2 so that the push button 6 is inserted into the push button hole 7, the attachment position of the cover plate 5 can be easily determined. Wiring is drawn out from the numeric keypad unit 18 and placed in the groove 4. 7 in the figure is a door stop. The wiring housed in the groove 4 reaches the upper end of the mullion 2 and is connected to a terminal block (not shown) housed in a cavity 22 formed in the upper frame 13. The terminal block connects the electric lock 3 and push button 6, and also connects these to a power line (not shown). That is, all the wiring of devices related to the electric lock 3 mounted on the door frame 1 is once gathered in a terminal block, and is connected to each other there. A cover plate 26 covering substantially the entire surface of the upper deck 13 on the indoor side is detachably attached with wood screws 27. This prevents the terminal block from being exposed and all wiring is concentrated on the terminal block, making repairs and inspections easier. A commercial power supply superimposed with a control signal for locking and unlocking the electric lock 3 is supplied to the power line drawn out from the door frame 1, so that the electric lock 3 can be opened and closed even at a location away from the door frame 1. There is. A stainless steel hakama 28 is attached to the lower edge of the door frame 1.
is attached, and at a portion of the hakama 28 corresponding to the mullions 2, the hakama 28 protrudes toward the indoor side, and a stepped portion 29 is formed by the upper end surface of the hakama 28 and the mullions 2. The lower end of the cover plate 5 is placed on the stepped portion 29, and the cover plate 5 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 5 is installed in a manner that floats upward by that much, and the cover plate 5
This has the advantage that the step on the floor does not get in the way when attaching and detaching. In addition, since the hakama 28 is made of stainless steel, it will not corrode, and prevents the wooden door frame 1 from coming into direct contact with the concrete floor surface, which easily absorbs moisture. This prevents corrosion.

[Effect of idea]

As mentioned above, the present invention fixes an electric lock/unlock push button in a fixed position of a door frame in a manner that projects toward the indoor side, and a cover plate that is detachably attached to the inner surface of the door frame. A push button hole with a shape that approximately matches the cross-sectional shape of the push button is drilled corresponding to this push button, so when attaching the cover plate to the door stop frame, you can simply insert the push button into the push button hole. This has the advantage that the mounting position of the cover plate can be easily determined.
