Description

[Detailed Description of the Invention] The present invention relates to a door panel that can reduce the labor of on-site construction and help stabilize quality by incorporating switches, electric appliances, etc. in advance.

Conventionally, electrical appliances such as lighting fixtures and electric fans that are used when entering and exiting a room are operated by operating a switch before entering the room, or by operating a switch after entering the room, so they are operated separately from the opening and closing operations of the door. Not only does it require a switch operation, which is time-consuming, but it also tends to lead to wasted power due to forgetting to turn it off.

In order to solve these problems, the inventors of the present invention proposed Japanese Patent Application Laid-Open No. 58-207463 (Patent Publication No. 1-1-1)
50749), Patent Application No. 93753 (Sho 57-93753)
No. 209823) etc., by making it possible to open and close an electric circuit through an electrical appliance in conjunction with the opening/closing operation of the door using an operating body such as a lock handle or grip provided on the door. We proposed a door device that automates the turning on and off of fixtures. However, when these switches, electric appliances, etc. are installed on-site, the construction efficiency is poor and the quality tends to be unstable.

The object of the present invention is to provide a door panel that can solve the above-mentioned problems by pre-installing switches, electric appliances, etc., and one embodiment thereof will be described below with reference to the drawings.

In the figure, the door panel 1 of the present invention has an opening 1

, a switch 5 that opens and closes an electric circuit EC through an electric appliance E such as a lighting fixture L and an electric fan F by opening and closing the door D using the operating bodies 3 and 4 of a lock 23 provided on the door D; The above-mentioned electric appliance E is integrated in advance. Further, in this embodiment, a push button switch 6 and an outlet 7 are further assembled. The door panel 1 divides the interior of the house into a space R1, which is a hallway, etc., and a space R2, which is a kitchen, a washroom, etc., and forms an entrance/exit part of the house. Further, the door D forms an inward opening door that opens toward the space R2.

The peripheral frame 2 has an upper frame member 1 between the vertical frame members 9 and 10.
1. A lower frame member 12 is spanned, and a hanging wall 13 is provided below the upper frame member 11, and the opening 14 that is opened and closed by a door D is formed below the hanging wall 13.

The vertical frame member 9 is provided with a door stop 16 on the surface facing the opening 14, and the door D is pivotally connected to the other vertical frame member 10, and the vertical frame members 9 and 10 are provided with grooves on their backs. 19 are formed vertically. Also, upper frame material 1
1 has a U-shaped cross section with a groove portion open at the top, and the groove portion is a partition plate 21 provided with a through hole 20;

An air outlet 22 is closed in a protruding portion of the bottom plate and the hanging wall 13 that protrudes toward the space R2.

The switch 5, as shown in detail in FIG.
The operating end of the lock 23 provided on the door D is directed toward the locking hole 20 into which the lock rod 24 is fitted, and is fixed within the groove 19.

Further, the lighting fixture L is attached to the front and back sides of the upper frame member 11, the push button switch 6 is installed above the switch 5 and on the vertical frame member 9 in this example, and the outlet 7 is installed below the vertical frame member 10. are respectively incorporated into the side faces facing the indoor space R2.

Such a switch 5, lighting fixture L, etc. are integrated into one body during construction or the like. Further, the lighting fixture L, the electric appliance E such as the electric fan F, the switch 5, and the like form an electric appliance circuit EC illustrated in FIG. 4, for example.

Note that the push button switch 6 can open and close the entire electrical circuit EC, and the outlet 7 is connected in parallel to the upstream side of the switch 6. The lighting fixture L is connected in series with a light-sensing switch Sa that prevents it from turning on when it is bright, and the electric fan F is connected in series with a slow-acting switch Sb. Wiring connections can also be completed at a factory, or integrated using crimp terminals and ring sleeves to the extent that wiring can be easily completed prior to construction.

Further, as shown in FIG. 2, the door panel 1 is installed by opening the upper frame material 11 onto the ceiling board 8, and
By connecting a duct T to the electric fan F, fresh air is discharged into the room from the air outlet 22.

The switch 5 is turned on and off in accordance with the movement of the lock lever 24 of the lock 23 using the operating bodies 3 and 4 when the door D is opened and closed.

In this embodiment, as shown in FIGS. 5 to 8, the lock 23 has the lock rod 24 in the opening position B, in which the door D can be opened by retracting the lock rod 24, and in the fully protruding position A. The switch 5 can be locked even in the incompletely extended position C, and the switch 5 is operated only in the fully extended position A.

The lock 23 includes the lock rod 24, a spring 25 that urges the lock rod to the fully extended position A, first and second operating bodies 3 and 4, and a spring 25 that biases the lock rod 24 to the fully extended position A. It is provided with a locking tool 26 for locking.

The lock rod 24 has a piece 30 at a position away from the tip.
At the same time, a protrusion 31 is provided at the rear end, and the lock lever 24 is biased forward by the spring 25 provided at the rear, so that the locking lever 24 is normally positioned so that the contact piece 30 is on the back side of the front 32. It can be located at the fully protruding position A where it abuts. Furthermore, the locking rod 24 is moved between this fully protruding position A and the opening position where the tip of the locking rod 24 moves back and approaches the front surface of the front 32 by operating the first and second operating bodies 3 and 4, allowing the door to be opened. It is housed so that it can reciprocate between it and B.

In the guide grooves on both sides of the lock lever 24, a first lever 33 is connected to the first operating body 3, and a second lever 33 is connected to the first operating body 3 and a second operating body 4 located on the center line of the circumference. Each upper end of the second lever 34 is inserted. The first lever 33 and the second lever 34 both have boss portions 35 and 36 at their bases, and the boss portion 35 has boss portions 35 and 36 that face rearward when the first lever 33 is in the forward tilted reference state. A locking groove 37 is recessed at the position.

A ratchet wheel 40 is loosely engaged with the boss portion 36,
The first lever 34 has a pin 41 therebetween.
A clutch 42 is provided that locks the two together only when the two are tilted backward.

The ratchet wheel 40 has a pawl portion having a locking surface 43 on the forward-inclined side of the second lever 34 at a pitch of 60 degrees. Further, a spring piece 45 below the front 32 comes into contact with the locking surface 43, and by locking the locking surface 43, rotation is made every 60 degrees and its reversal is prevented. Further, when rotated by more than 60 degrees, for example, 75 degrees, the claw portion can be pressed to reverse the rotation to a 60 degree rotation position where the back surface and the spring piece come into close contact.

A gear 46 is integrally formed on the ratchet wheel 40. The gear 46 meshes with a pinion 47 on the back of the case, and the pinion 47 rotates 90 degrees for every 60 degree rotation of the gear 46.
Can be rotated by degrees. A cam 50 is attached to the pinion 47.
are integrally formed.

The cam 50 has a substantially elliptical shape, and its major axis and minor axis can be positioned vertically or horizontally at every 60 degrees of the ratchet wheel 40. The lower end of a locking tool 26, which is a rod-shaped follower mounted vertically and movable up and down and biased downward by a spring, is in sliding contact with the cam 50, and further drives a locking piece 53. The lock piece 53
is a rectangular plate in which the cam 50 is rotatably housed, and when the short shaft side of the plate comes into contact with the cam 50, the locking piece 53 moves forward, and the protruding piece 54 at the tip of the plate moves forward.
is fitted into the locking groove 37, and the first lever 3
3, that is, the first operating body 3 can be locked. The operating bodies 3 and 4 are fitted into and fixed to the boss portions 35 and 36, and the first and second levers 33 and 34 are urged forward in a forward tilting direction by springs.

Therefore, when the first operating body 3 is pushed down to open the door D when entering the space R2 from the space R1, the first lever 33 pushes the rear end of the guide groove, and the lock lever 24 can be freely reciprocated between the fully extended position A and the opening position B where the door can be opened (as shown in FIG. 6). By pulling the lock lever 24 using the operating body 3, the lock lever 24 moves away from the switch 5, turning on the switch 5, closing the electric circuit EC and energizing it. By releasing the first operating body 3 when entering the room, the lock lever 24 is positioned at the fully extended position A by the spring 25.

Next, the second lever 34 is moved backward by operating the second operating body 4 on the side through which the door D was passed through to close it, that is, on the space R2 side. The second lever 34 is
The lock lever 24 is moved back by contacting the rear end of the guide groove, and at the same time, the ratchet wheel 40 is rotated in the same direction via the clutch 42. Every 60 degrees of rotation of the ratchet wheel 40, it passes over one pawl, and the cam 50 rotates about 90 degrees approximately perpendicularly to its long axis. Furthermore, the second lever 34 is
By passing through the 60 degree position and rotating, for example, 75 degrees as shown in FIG. 7, the lock rod 24 is retracted to its opening position B. In the state shown in FIG. 7, the spring piece 45 and the locking surface 43 are separated and brought into close contact with each other as the second lever 34 returns, thereby correctly rotating the ratchet wheel 40 by 60 degrees.

Note that while the lock rod 24 is retracting, the locking tool 26 pushed up by the cam 50 locks the protrusion 31 of the lock rod 24, and as shown in FIG. Hold at protruding position C.

Note that the lock piece 53 that slides into contact with the short shaft side of the cam 50
The protruding piece 54 engages with the locking groove 37 and restrains the operating body 3.

The lock 24 therefore leaves the switch 5 and continues to close the electrical circuit EC. Furthermore, when leaving the room, by operating the second operating body 4 in the same manner, the cam 50
is rotated 90 degrees, so that the catch 26 is lowered. Also, by retracting the lock piece 53, the lock rod 2
4 to its full protrusion position A, and at the same time
The operating body 3 is opened.

As a result, when leaving the room, the door can be closed using the operating body 3, and when the door is closed, the lock rod 24 is projected to the fully extended position A by the spring 25, and the switch 5 is pushed. As a result, the electric circuit EC is opened and, for example, the light is turned off, and the switch 5 is automatically turned on and off by opening and closing the door D of the operating bodies 3 and 4, thereby opening and closing the electric circuit EC.

As mentioned above, the door panel of the present invention turns on the electric circuit that includes the electric appliance by opening and closing the door.
The turn-off switch, electrical appliances, lock, etc. are integrated into one unit, and most of the assembly work can be done at the factory, and the door panel can be installed on site using only simple work using crimp terminals, ring sleeves, etc. After installation, the construction can be completed with only external wiring, which improves the efficiency of on-site work and stabilizes the quality of assembly. Furthermore, since the electric circuit can be opened and closed by operating the operating body without using a key or the like, it is convenient to open and close the door.
