Description

[Detailed Description of the Invention] The present invention relates to a door device that can open and close an electric circuit, making it convenient to turn on and off lights, and by attaching a pilot lamp, it is possible to visually check whether the lights are on or off indoors from the outside.

Conventionally, when entering and exiting a room, lighting fixtures, for example, are turned on by operating a switch before entering the room, or by operating a switch after entering the room, but in both cases, the door must be turned on to turn on and off. A switch operation separate from the opening/closing operation is required, which is time-consuming, and it is easy to waste electricity by forgetting to turn it off.Furthermore, if the light is turned on after entering the room, it is necessary to enter the dark room when the door is opened, making it difficult to operate the switch. There are also drawbacks, such as the time it takes.

The inventors of the present invention have submitted the patent application No. 57-93753.
-209823), by providing operating bodies on both sides of the door and making it possible to close the electrical circuit by closing the operating body located on the side through which the door passes through, lighting fixtures, etc. can be turned on. We proposed a device that can be automated.

This device can be lit by a clearly located operating body, thus making its lighting operation easy. However, unlike a switch, this type of light is turned on and off simply by using an operating body, so
Unlike conventional devices that have an external light on/off switch, the lighting status inside the room cannot be visually confirmed from the outside depending on the switch position.

The object of the present invention is to provide a door device that can solve the above-mentioned problems by providing a pilot lamp, and one embodiment thereof will be described below with reference to the drawings.

In Figures 1 to 3, the door device of the present invention includes a lock body 1a attached to the tip of a swinging door D, a control tool 34 attached to an opening frame F, and a lighting device L for room lighting.
and a pilot lamp that indicates whether it is on or off.
Includes PL. Further, first and second operating bodies 3 and 4 are arranged on both sides of the door D.

The door D opens and closes an opening provided in a wall W that partitions the inside of the building into two spaces R1 and R2, and the door D is formed as a single-swing door that opens toward the space R2. In this embodiment, the space R1 is, for example, a hallway, and the space R2 is a room where the lights are normally turned off, such as a washroom, bathroom, or storage room. Further, the vertical frame material F forms the wall W together with other frame materials surrounding the opening.

The first and second operating bodies 3 and 4 include handles 3a and 4a that protrude from the lock body 1a and are located on the door edge side of the door D and are rotatably attached to both sides of the door D. , and the lock body 7 is, as illustrated in FIG.
A lock rod 11 biased forward by a spring 10 is housed in the case 9. This lock rod 11 has a protruding position A where a contact piece 12 formed from the tip abuts against the front 13 of the case 9, and a protruding position A where the front 13 is in contact with the front 13.
The door D can be moved between the retracted position B, where the door D can be opened by substantially retracting therein, and the protruding position A can be moved in the free state by being biased by the spring 10. There is.

Also, the lock rod 11 has pins 14 symmetrically on both sides thereof.
15, and the upper ends of the first and second levers 19 and 20 connected to the support shafts 16 and 17 of the first and second operating bodies 3 and 4 are exposed in front of the pins 14 and 15, respectively. Let it happen. First and second levers 19, 20
is, when the handles 3a and 4a are located horizontally, the pin 1
The handles 3a, 4a are held substantially vertically in front of the handles 4, 15, and are urged toward the pulling side by appropriate spring means (not shown).

Therefore, by pulling down and rotating the first operating body 3, the first
The lever 19 presses the pin 14 and the lock lever 11 is moved from the extended position A to the retracted position B. Also, operation body 3
When the user releases the lock lever 11, the lock lever 11 is moved to the protruding position A by the spring 10.

Note that since the support shafts 16 and 17 are separated, while the first lever 19 is operating, the second lever 20
stands still.

Furthermore, the second operating body 4 also allows the first operating body 3 to
The lock rod 11 can be moved from the protruding position A to the retracted position B independently of this, and the lock rod 11 can be returned to the protruding position A by the spring 10.

Further, the lock rod 11 has a rectangular shaft shape with both sides of the protruding portion that protrudes from the case 9 at the protruding position A having planes parallel to the longitudinal direction of the lock rod 11.

Thereby, the protruding portion forms a blocking portion 27 that protrudes from the case 9 and prevents the door D from being closed when the door D is closed. The blocking portion 27 is the tip of the lock rod 11, so that the first and second operating bodies 3,
By pressing down in step 4, it retreats to the retracted position B.

A changeover switch 30 is attached to the support shaft 17 that supports the second lever 20 of the second operating body 4.

The changeover switch 30 is a snap switch such as a rotary switch or a pull switch, and is turned ON and OFF each time. Also, the support shaft 1
As described above, each time the handle 4a rotates in conjunction with the second operating body 4,
Repeats ON and OFF operations alternately.

The opening frame F is provided with a receiving plate 1b. Receiving plate 1b
is a substantially T-shaped plate with a narrow protruding piece integrally provided at the base, and a locking hole 42 into which the blocking portion 27 can be inserted is bored at the base. Also, a cushioning material 47 is attached to the tip of the protruding piece. The buffer material 47 is made of an elastic material such as rubber and has a cylindrical shape. Further, the receiving plate 1b is attached to the vertical frame member F by positioning a buffer material 47 on the side edge facing the door D to be closed. This allows the protruding blocking portion 27 to abut against the cushioning material 47.

In addition, the locking hole 42 is a hole 3 recessed in the vertical frame material F.
6, and a control device 34 made of, for example, a micro switch is housed in the hole 36 with the operating end 35 extending from the receiving tube 37 facing outward. The changeover switch 30 and the control device 34 are connected to an electric circuit E shown in FIG.
Further, electric appliances 32 such as a room illumination lamp L, a pilot lamp PL, a ventilation fan F, and a heater H are connected in parallel to the electric circuit E. Thereby, the pilot lamp PL can indicate whether other electric appliances 32 such as the lighting fixture L are turned on or off.
Note that the lighting fixture L is arranged in one space R2 such as the hand-washing room, and is also equipped with a pilot lamp.
PL is the other space R1, which is the entry side of the vertical frame material F.
It is installed in the recess provided on the side. Therefore, by turning on the changeover switch 30 and the control device 34, the relay R is turned on.
By activating the a contact (make contact) r, the electric appliance circuit E is closed, and the electric appliance 3
2 can be energized. Note that the electrical circuit E can be configured by using the changeover switch 30 and the control device 34 without using the relay R.
It can also be driven directly by. Control tool 3

is pressed and connected to the normally closed state, so that the electric appliance circuit E can be closed by retracting the lock 11, and when the lock 11 is released while the door is in the open state, the electric appliance circuit E can be closed. The circuit E can be kept open. In addition, 38 is a manual switch, M
is the main switch.

Next, the operation of the door device 1 will be explained. People are space R2
When the door is closed after exiting from the room to the space R1, the changeover switch 30 is in the OFF state, and the control tool 34 is pressed by the lock 11. Therefore, the electric appliance circuit E is opened, and the electric appliance 32 including the pilot lamp PL is turned off.

Next, when entering from space R1 to space R2,
Because the pilot lamp PL is off,
It can be visually confirmed that no one enters the space R2. Also, the handle 3a of the first operating body 3 is pulled down to move the lock rod 11 backward. When the door D is opened, the operating end 35 of the micro switch of the control device 34 is extended and turned ON, thereby closing the electrical circuit E and energizing the electrical appliance 32. While the door D is open, the control tool 34
It is opened and the electrical circuit E is kept closed.
Note that depending on the first operating body 3, the changeover switch 3
0 does not operate and is in the OFF state.

After opening the door D, the user enters the lit space R2. Further, after releasing the first operating body 3 and changing the grip to the second operating body 4 located on the space R2 side, that is, on the side through which the door D passes, the door D is closed using the handle 4a. As described above, in the free state, the tip of the lock rod 11, that is, the blocking portion 27 protrudes to the protruding position A and abuts against the cushioning material 47. In order to close the door, it is necessary to operate the second operating body 4 linked to the lock lever 11, and therefore, by blocking this operation, the operating part 27
Retracts to enable closing operation. Further, by this operation, the changeover switch 30 is turned on, and the electrical circuit E is maintained in a closed state. When the door D is closed, the lock 11 of the door D protrudes into the locking hole 36 to turn off the control device 34, but the changeover switch 30 connected in parallel thereto can maintain the lighting state of the electric appliance 32. Also, the pilot lamp PL lights up,

Next, when exiting, the changeover switch 30 is turned OFF by the next operation of the second operating body 4. However, the control device 34 is turned on due to the separation of the lock lever 11.
do. Therefore, the electrical circuit E is closed while the door is open when leaving the room. Note that the user leaves the space R1 and closes the door D while retracting the lock lever 11 using the first operating body 3.

Note that when closing, the presence of the blocking portion 27 prevents the first operating body 3 from closing.
is definitely manipulated. Also, the operation piece 2 due to forgetting to operate it
The buffer material 47 cushions the collision between the support plate 1b and the support plate 1b.

Furthermore, by releasing the hand from the first operating body 3, the lock rod 11 protrudes into the locking hole 36.
Both the changeover switch 30 and the control device 34 are OFF.
The electric appliance 32 is turned off by opening the electric appliance circuit E.

As mentioned above, the door device of the present invention can be turned on and off by moving the lock lever as the door is opened and closed, and the lighting equipment can be turned on and off. In addition, a pilot lamp is installed to indicate whether the lighting device is on or off, so by installing this lamp externally, the internal lighting status can be seen from the outside. Since it is installed on the vertical frame material in the space opposite to the side where the lighting device is installed, it is possible to easily check whether the light is on or not before operating the operating body, improving usability and making it easier to lock the lock. By making the protruding part into a square shaft shape, it functions as a blocking piece that prevents the door from closing.
To ensure reliable operation of inserting and removing the lock lever.
