Description

[Detailed description of the invention] This invention consists of a lock body and a receiving plate, and can open and close electrical circuits connected to lighting equipment etc. with ease of operation, and by providing a buffer material on the receiving plate, the lock can be easily opened and closed. This invention relates to a door device that reduces impact and prevents damage.

Conventionally, when entering and exiting a room, for example, lights are turned on by operating a switch before entering the room, or by operating a switch after entering the room. A separate switch operation is required from the opening/closing operation of the door, 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. It also has drawbacks such as being time consuming to operate.

As a solution to some of these drawbacks, by always biasing the door toward the open side and closing the door,
There are lights that turn on by automatically closing an electric circuit, and lights that turn on automatically when the door opens, eliminating the inconvenience of operating a switch in a dark room.However, lights that leave the door open all the time improve the appearance of the residence. Also, if the door lights up when the door is opened, the door is likely to be left open, and the lighting will remain on at that time, resulting in a waste of power, similar to the above-mentioned case of forgetting to turn it off.

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, lighting of lighting equipment, etc. We proposed a device that can be automated. This proposal also discloses that in order to ensure that the lights turn on and off as the door opens and closes, a blocking part that protrudes when the door opens and prevents the door from closing is provided. Because it collides with the receiving plate, the impact force tends to cause unreasonable action on the blocking part and the receiving plate.
There was a risk that it would be damaged.

The present invention aims to provide a door device that can solve this problem, and one embodiment thereof will be described below with reference to the drawings.

In Figures 1 to 4, the door device 1 of the present invention includes a lock body 1a attached to the free end of a swinging door D, and a receiving plate 1b attached to a vertical frame member F of a wall W facing the lock body 1a. , and the door D has a first,

a and 4a are biased toward the pulling side.

Therefore, by pulling down and rotating the first operating body 3, the first
The lever 19 presses the pin 14 to move the lock rod 11 from the protruding 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.

Also, by the second operating body 4, the first operating body 3
The lock rod 11 can be moved from the protruding position A to the retracted position B independently of the above, 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 first control tool 30 is attached to the support shaft 17 that supports the second lever 20 of the second operating body 4 .
The first control device 30 is, for example, a snap switch such as a rotary switch or a pull switch, and is a changeover switch that repeats ON and OFF every time. Also, by being interposed on the support shaft 17, each time the handle 4a rotates in conjunction with the second operating body 4,
Repeat ON and OFF operations alternately as described above.

The receiving plate 1b has, as shown in FIGS. 3a and 3b,
Approximately T with a narrow protruding piece 41 integrally provided on the base 40
The blocking portion 27 is attached to the base 40 of the board.
A locking hole 42 into which the screw can be inserted is bored. Also, protruding piece 4
A narrow bent portion 45 that is bent at right angles is provided at the tip of the projecting piece 41, and the buffer member 47 is attached to the tip of the protruding piece 41. The buffer member 47 is made of an elastic material such as rubber and has a cylindrical shape, and is provided with an L-shaped groove 49 from the lower surface to the vicinity of the upper end into which the bent portion 45 can be inserted together with the tip of the protruding piece 41. The buffer member 47 is fixed by fitting the receiving plate 1b into the groove 49 and using an adhesive or the like.

The receiving plate 1b is attached to the vertical frame member F by positioning the 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 buffer material 47.

In addition, the locking hole 42 is a hole 3 recessed in the vertical frame material F.

5 to 8 show that the first and second Another embodiment of the invention is shown in which the controls 30, 34 can be integrated as a control 35 consisting of, for example, one microswitch.

The lock body 1a operates the lock rod 11 by operating the second operating body 4 of the first and second operating bodies 3 and 4.
It can be locked at the incompletely protruding position C.

The control tool 35, like the first control tool 30 shown in FIGS. 1 to 4, is installed in the locking hole 36 with its operating end 37 facing the lock rod 11, and is not operated at the protruding position A. While the end 37 is pressed against the locking rod 11,
At the incomplete protrusion position C, they are separated.

The lock rod 11 has a contact piece 55 at a position away from the tip, and a locking protrusion 56 whose lower back surface is sloped is provided at the rear end. The lock rod 11 has two positions: a protruding position A in which the lock rod 11 is inside the flat case 57 and the abutment piece 55 abuts against the back surface of the front 58, and a closed position B in which the lock rod 11 is retracted and substantially recessed into the front 58 to open the door.
It is installed so that it can be reciprocated between. Also lock rod 1
1 can be moved by being urged toward the protruding side by a spring at the rear end, and can be located at the protruding position A in a free state. Also, on both sides of the lock rod 11, there is a groove extending rearward from the back of the piece 55, and the groove is connected to the side piece 55.
9, the guide grooves 61, 62 are closed.
is formed. The upper ends of the first lever 19 and the second lever 20 are inserted into the guide grooves 61 and 62. Both the first lever 19 and the second lever 20 have boss parts 69 and 67 in which square holes 66 and 67 are formed concentrically at their bases, respectively. , a locking groove 71 is recessed in a position facing rearward in the standard state of forward leaning. The boss portion 70 is formed with a clutch groove 72 that increases in depth in the rearward direction of the second lever 20.
The clutch groove 72 accommodates a clutch pin 75 using a cylindrical pin that comes into contact with the inner surface of a ratchet wheel 74 that fits into the boss portion 70. The ratchet wheel 74 has a second
A claw portion 80 having a locking surface 79 extending in the radial direction is formed on the forward-inclined side of the lever 20 at a pitch of 60 degrees. Note that the back surface of the claw portion 80 is formed into a plane 81 extending from the tip of the claw portion 80 to the root portion. A substantially U-shaped spring piece 82 below the front 58 of the case 57 comes into contact with the flat surface 81 and is locked by the locking surface 79 to prevent the flat surface 81 from being reversed every 60 degrees. 60 again
When rotating an angle exceeding 75 degrees, for example,
By pressing the claw portion 80, the flat surface 81 and the spring piece 82 can be rotated by 15 degrees, which is the angular difference, to a 60 degree rotation position where they abut.

A gear 84 is integrally formed on the ratchet wheel 74. The gear 84 meshes with a pinion 85 that is pivotally supported on both sides of the back of the case 57.
Since the number of teeth is 1:1.5 compared to the gear 84, it is possible to rotate 90 degrees for every 60 degree rotation of the gear 84. A cam 87 is integrally formed with the pinion 85. The cam 87 has a substantially elliptical shape, and its major axis and minor axis can be positioned vertically or horizontally each time the ratchet wheel 74 rotates 60 degrees. Also, a range α that is about 20 degrees from the long axis in the opposite direction to the rotational direction of the cam 87 (shown in Fig. 7)
is formed into an arc whose radius is its center.

The lower end of a follower 90, which is vertically and slidably attached to a support piece 89 extending from the back plate of the case 57, comes into contact with the cam surface of the cam 87. The follower 90 is urged downward by a spring 91.

The cam 87 further causes the locking piece 97 to follow. The locking piece 97 is a rectangular plate provided with a hole 99 in which the cam 87 is rotatably inserted,
Spring 103 inserted between the case 57 and the back plate
is urged forward, and the back surface of the hole 99 comes into sliding contact with the cam 87. When this back surface comes into contact with the cam surface on the short shaft side of the cam 87, the locking piece 97 moves forward.
The protruding piece 102 provided at the tip of the locking groove 71
The first lever 19 can be locked.

The first and second operating bodies 3 and 4 have handles 3a and 4a, and square shafts 3b and 4b protruding from the center thereof are fitted into the square holes 66 and 67, respectively. Also, the first and second levers 19 and 20 are operated by springs 105 and 106.
It is urged in the forward tilting direction and normally stops at its reference position with clearances 61a and 62a between the guide grooves 61 and 62 at the front. Note that the first and second levers are 1
9 and 20 hold their handles 3a and 4a horizontally in the reference position.

By pushing down the handle 3a of the first operating body 3, the first lever 19 moves freely in the guide groove 61 and then presses the rear end of the guide groove 61, causing the lock lever 11 to move.
is moved from its protruding position A, where the contact piece 55 contacts the front 58, to its retracted position B, where the tip of the lock rod 11 is located near the front 58 and the door can be opened (as shown in FIG. 6). When the operating body 3 is released, the lock rod 11 is urged by the spring and protrudes to the protruding position A. Note that the tip of the lock rod 11 is
Similarly to the embodiment shown in FIG. 4, a blocking portion 27 having a square shaft shape is formed.

Note that by pulling the lock lever 11 using the first operating body 3, the lock lever 11 is separated from the control tool 35 and the electric circuit 33 is closed. Note that while the lock rod 11 is being moved by the first lever 19, the second lever 20 is stationary. Next, for closing, the second lever 20 is tilted backward by operating the second operating body 4 on the pass-through side. The second lever 20 comes into contact with the rear end of the guide groove 62 and moves the lock rod 11 backward. At the same time, the ratchet wheel 74 is rotated in the same direction via the clutch pin 75. The 60 degree rotation of the ratchet wheel 74 causes the cam 87 to pass over one of the pawls 80, and due to the engagement between the gear 84 and the pinion 85, the cam 87 is rotated 90 degrees perpendicularly to its long axis. Further, by rotating the second lever 20 through the 60 degree position and, for example, 75 degrees as shown in FIG. 6, the lock rod 11 is retracted to the retracted position B. In addition, at the 75 degree position, the claw part 80
is urged in the reverse direction by the spring piece 82,
Accordingly, as the lever 20 is reversed by the spring 106, the clutch pin 75 is released, and as a result, the lever 20 correctly returns to the 60 degree position where the spring piece 82 and the flat surface 81 come into contact. During the return, the follower 90 pushed up by the cam 87 touches the protrusion 5 of the lock rod 11.
6 is engaged, and the lock rod 11 is held in its incompletely protruding position C as shown in FIG. Also, the protruding piece 102 of the locking piece 97 that slides on the short shaft side of the cam 87 is in the locking groove 71.
, and restrains the first operating body 3. This restriction prevents new persons from entering space R2. Also, the lock lever 11 separates from the control tool 35, closes the electric circuit 33, and turns on the electric appliance 32. Furthermore, when leaving the room, the second
By operating the operating body 4, the cam 87 is
It rotates 90 degrees, thus pushing down the follower 90 and retracting the locking piece 97. Thereby, the lock rod 11 can be projected to the projecting position A by the spring.
This allows the first operating body 3 to be released. As a result, when leaving the room, the door can be closed using the first operating body 3, and when the door is closed, the lock rod 11 is projected by the spring to the projecting position A, and the control tool 35 is pushed, the electric circuit 33 is opened, and the light is turned off.

In this manner, in this example, when the long axis of the cam 87 is located in the horizontal direction, the lock rod 11 can be moved from the protruding position A to the retracted position B by operating the first operating body 3. The lock rod 11 can be locked at the incompletely protruding position C by operating the second operating body 4, and the second operating body 4
By repeating this operation, the cam 87 can be rotated every 90 degrees. Therefore, the lock rod 11 can reciprocate by alternately repeating strokes between the protruding position A and the retracted position B, and between the incompletely protruding position C and the retracted position B. Therefore, the electric circuit 33 can be controlled using one control tool 35 in the same manner as in the embodiments shown in FIGS. 1-4.

As mentioned above, the door device of this study can open and close electric circuits by operating the operating body associated with opening and closing the door, making it convenient to turn on and off lights in the room. In addition, the light can be turned on only when necessary, preventing forgetting to turn it off, and eliminating the feeling of anxiety when entering a dark room. In addition, by providing a blocking part that prevents the door from closing at the protruding position, it is essential that the blocking part is moved back by operating the operating body, and since the electric circuit is opened and closed by operating this essential operating body, the electrical The opening and closing operation of the circuit is ensured. Further, the buffering material of the receiving plate alleviates the impact caused by the collision with the blocking portion and prevents damage thereto.
