Description

[Detailed Description of the Invention] [Technical Field] By providing a lock that is held at a partially extended position between a fully extended position and a door opening position, and operating a control tool using this lock, For example, it is possible to turn on and off electric circuits that involve electrical appliances such as lighting fixtures placed inside or outside the room, simplifying operations such as turning on and off lights, and saving power. This invention relates to a locking device that prevents overheating, electrical leakage, etc. and contributes to safety.

[Background technology]

Conventionally, lighting fixtures, heaters, etc. are turned on when entering and exiting a room, either by operating a switch before entering the room, or by switching on after entering the room. However, in both cases, turning on and off the lights requires a separate switch operation from the opening/closing operation of the door, which is time-consuming.In addition, it is easy to waste electricity by forgetting to turn them off, and it is easy to forget to turn them off. In some cases, there are risks such as overheating and electrical leakage. Furthermore, those that turn on after entering the room have the disadvantage that they must be entered into the lip room when the tiles are released, making it time-consuming to operate the switch.

One way to solve this problem is to always bias the door to the open side and automatically turn on the electric circuit when the door is closed, so that the light turns on when the door is opened. There is a type that uses a self-FJ + small light for all three types, which eliminates the inconvenience of operating switches in a dark room, but one that leaves the door open all the time; The door is likely to be left open, and at that time the light remains on, resulting in wasted power and danger, as in the case of forgetting to turn it off.

On the other hand, various types of locks have been known in the past, such as so-called locking rods and monolocks, which have locking rods for final tightening, filling, etc. It reciprocates between the door position and the fully extended position, and can only be held in the fully extended position.

With such conventional lock devices that can only be held in the fully extended position, depending on the position of the lock lever, the state of the room being occupied and after leaving the room cannot be distinguished by the key itself, and the above-mentioned automatic lighting/extinguishing operation cannot be performed. The device that does this cannot be configured.

[Purpose of the invention]

The present invention has a lock that can be held in a partially extended position between a fully extended position and an open door position, and by operating a control device using the lock, electrical appliances such as lighting fixtures and fans can be controlled. The purpose of the present invention is to provide a lock device that can automatically turn on and off lights and facilitates switch operation.

[Disclosure of the invention]

Embodiments of the present invention will be described below in sequence based on the drawings.

1 to 6 show a basic embodiment of the present invention, and a lock device 1 includes a lock main body 2a and a receiving plate 2b that are attached to a door. The door opens the inside and outside of the building into two spaces R1,
A wall opening provided in a wall W that partitions R2 is opened and closed, and the door opens, for example, from space R1 to space R2 (formed as an inward swinging door. In this embodiment, space R1 is, for example, a hallway). Arrival space R2 is for the washroom, bathroom, storage room, etc.
'M is the room where the lights are turned off.

The lock body 2a includes first and second operating bodies 3.4 protruding from both sides of the door, and the first and second operating bodies 3.4 are connected to the handle 3.
b, 4b, and is rotatably mounted. As illustrated in FIG.
1 to its fully protruding position, where the abutting piece 12 formed from the tip of 1 protrudes until it abuts on the front 13,
Pull the lock rod 11 toward the front 13 side, and
The lock lever 11 is housed so that it can reciprocate between the opening position B and the opening position B, where the IPD can be opened by almost immersing the IPD.
For example, it can be locked even at the incompletely protruding position Hc between the open door position WB and the fully protruding position.

In this example, the lock body 2a can lock the lock rod 11 at the incompletely protruding position C by operating, for example, the second operating body 4 of the first and second operating bodies 3.4.

The receiving plate 2b into which the lock rod 11 is fitted is a substantially T-shaped plate,
A locking hole 17 is bored in its base, and a cylindrical buffer material 5 is attached to its tip. Note that the receiving plate 2b is attached to the vertical frame material F,
By attaching the cushioning material 5 to the open side of the door, when the protruding lock rod 11 engages with the cushioning material 5, it is buffered. In addition, the locking hole 17 communicates with a hole recessed in the vertical frame member F, and in the hole, a control tool S consisting of, for example, a one-swivel notch in each hole is inserted with its operating end Sa outward. The direction is conjunctival.

Furthermore, on the vertical frame material F, there is a bi-Nissan solar lamp P on the outdoor side.
L is attached. As shown in Fig. 3, the control device S and the switch SO are connected in parallel to an electric circuit EC that connects a pilot lamp PL2 lighting device, a ventilation fan F, a heating device H, and other electric appliances E, and their operation activates a relay R. When activated, the electric circuit EC is turned on, and the electric appliance connected to the contact R can be energized. In addition, the electric circuit EC is a relay R
It is also possible to directly drive the controller S without using the controller. The control tool S is moved to the fully extended position of the lock rod 11, and the end Sa is pressed to switch between ON and OFF, and the microswitch is connected to the normally closed state, so that the lock rod 1 is turned on. When the electric circuit 1)C is turned ON by reversing the electric circuit 1), and the gate position △ is at the incompletely protruding position C, the lock 11 is engaged, thereby maintaining the ON state of the electric circuit 1). Depending on the circuit conditions, it is natural that the connection can be made such that it is turned off by contact with the lock rod 11.

Further, the locking rod 11 has a protrusion 21 at its f end with a sloped lower surface for use in locking. The locking rod 11 has grooves extending rearward from the back of the contact piece 12 on both sides, and the guide groove 22 is closed by closing the cough groove with a presser piece.
23 is formed. The guide grooves 22 and 23 have carefully constructed bodies 3.
The upper ends of the first lever 19 and the second lever 20 attached to the support shafts 3a and 4a of No. 4 are inserted. 1st lever 1.9
, ff52 (7) The levers 20 and 20 each have boss portions 29 and 30 having square holes concentrically drilled at their bases, and the boss portions 29 have boss portions 29 and 30 that are arranged so that when the first lever 19 is in the forward tilted reference state, , a locking groove 31 is recessed in a position facing rearward. The boss portion 30 is formed with a clutch groove 32 that increases in depth in the direction of inclination of the second lever 20.
2 houses a club/seven pin 35 using, for example, a cylindrical pin, which also comes into contact with the inner surface of the claw mold 34 that fits into the boss portion 30. The pawl type 34 includes a pawl portion 40 having a locking surface 39 extending radially on the forward-inclined side of the second lever 20.
Form at 0 degree pisoji. Further, the back surface of the claw portion 40 is formed into a plane 41 extending from the tip of the claw portion 40 to the root portion. A substantially U-shaped spring piece 42 attached to the lower part of the front 13 of the case 14 comes into contact with the flat surface 41, and is locked by the locking surface 39 to rotate an angle exceeding 60 degrees, for example, an angle of 75 degrees. At this time, by pressing the claw portion 40, the flat surface 41 and the spring piece 42 can be rotated by 15 degrees, which is the angular difference, up to any rotation of 60 degrees where they come into contact with each other. A gear 46 is integrally formed on the claw mold 34. The gear 46 meshes with a pinion 47 that is pivotally supported on both sides of the back of the case 14, and the number of teeth of the pinion 47 is set at a ratio of 1:1.5 compared to the gear 4G. It can rotate by 90 degrees for every (g) 0 degree rotation of the gear 46. A cam 50 is integrally formed with the pinion 47. The cam 50 has a substantially elliptical shape, and its long axis and short axis are positioned vertically or horizontally every 60 degrees of rotation of the claw mold 34. A follower 52 is attached to the cam 50 so as to be vertically slidable on a support piece 51 extending from the back plate of the case 14.
The lower end abuts the cam surface. The follower 52 is the locking rod 1
1, and is biased downward by a spring. The cam 50 further causes a locking piece 55 to follow. The locking piece 55 is a rectangular plate having a hole in which the cam 50 is rotatably inserted, and is biased forward by a spring 56 inserted between the locking piece 55 and the back plate of the case 14. While the back surface of the hole comes into sliding contact with the cam 50, when the back surface comes into contact with the cam surface on the short axis side of the cam 50, the locking piece 55 moves forward, and the protruding piece 57 provided at its tip engages the locking piece 57. The first lever 19 can be locked by fitting into the stop groove 31 . The first and second levers 19.20 are biased forward in a forward tilting direction by springs, and are normally stopped at their reference positions having clearances 22a, 23a between them and the guide grooves 22.23. Note that the first and second
In the reference position, the levers 19, 20 of
Hold b horizontally.

By pushing down the handle 3b of the first operating body 3, the lock main body 2a moves the first lever 19 in the guide groove 22, and then pushes and pulls the rear end of the guide groove 22, thereby moving the lock rod 11. From the fully protruding position where the contact piece 12 contacts the front 13,
The tip of the lock rod 11 is located near the front 13 and can freely reciprocate (as shown in FIG. 4) up to the opening position B where the door can be opened. In this state, when the operating body 3 is released, the lock rod 11 protrudes to the fully extended position. Therefore, in this state, when closing, the lock rod 11 collides with the periphery of the wall opening, making it impossible to close the door. A lock rod 11 with parallel parts constitutes a blocking piece 6 that prevents the door from closing.

In addition, when entering the space R2, the lock lever 11 is pulled using the first operating body 3 (thereby, the lock lever 11 moves away from the control tool S and closes the electric open circuit EC. During the movement of the locking rod 11, the second lever 20 moves in the guide groove 2.
It is stopped within the play gap 23a of No. 3. Next, by operating the second operating body 4 on the side through which it passed for closing, the second lever 20 is tilted backward. The second lever 20 has a guide groove 23
At the same time as the lock lever 11 is moved back by contacting the rear end, the pawl mold 34 is rotated in the same direction via the thalassodie pin 35. When the pawl mold 34 rotates 60 degrees, it climbs over one pawl 40, and due to the engagement between the gear 46 and the pinion 47, the cam 50 is rotated 90 degrees with its long axis perpendicularly, and the second lever 20 is rotated 60 degrees. For example, by rotating the lock rod 1 by 75 degrees as shown in FIG.
1 retreats to its open door position B. Note that at the 75 degree position, the claw portion 40 is urged in the reverse direction by the spring piece 42, and accordingly, as the lever 20 is reversed, it correctly returns to the 60 degree position where the spring piece 42 and the flat surface 41 come into contact. In addition, during the return, the follower 5 is pushed up by the cam 50.
2 functions as a locking tool 7 that locks the protrusion 21 of the lock rod 11 and holds the lock rod 11 in its incompletely protruding position C as shown in FIG. Also, a locking piece 5 that slides into contact with the short shaft side of the cam 50
The protruding piece 57 of No. 5 engages with the locking groove 31 and restrains the first operating body 3. Therefore, the lock LTII moves away from the control device S, closes the electric circuit EC, and lights up the electric appliance E. Furthermore, by operating the second operating body 4 in the same manner when leaving the room, the cam 50
is rotated by 90 degrees, and therefore, by pushing down the follower 52 and retracting the locking piece 55, the lock rod 11 can be projected to its fully extended position, and the first operating body 3 can be opened. As a result, when leaving the room, the door can be closed using the gAl operating body 3, and when the door is closed, the lock rod 11 is extended to the fully extended position, the control tool S is pushed, the electric circuits F and C are opened, and the light is turned off, for example.

In this way, in this embodiment, the electric circuits F and C can be turned on by operating the second operating body 4 on the pass-through side of the door. Since the easily recognizable operating body 4 can be used, lighting of the room can be done without any trouble. In addition, the electric circuit EC that normally supplies electricity to the electric appliance E in the space R2 can be shut off, and by turning on the lamp only when necessary, it achieves a power saving effect and prevents the danger of electric leakage and overheating due to forgetting to turn it off. Furthermore, since the electric circuit ECfc can be turned on when the door is opened and maintained in the ON state while the door is open, operability is improved by eliminating the feeling of anxiety when entering a dark room. Further, by providing the blocking piece 6, the closing of the door (2) and the closing operation of the electric circuit EC are ensured. Furthermore, when switch SO is operated, electric circuits F and C can be forcibly turned on, and electric appliance E can be turned on regardless of whether anyone enters or leaves the room. Therefore, even if several people enter the room at once and leave the room randomly, the light can be turned on by the switch SO as long as there are people entering the room. Further, the lighting state of the pilot lamp PL in the room R2 can be visually confirmed from outside, and the operation of the control tool S can be confirmed.

7 to 11 show still other embodiments of the present invention using different box locks 2a.

The lock rod 11 has a guide groove 22 which forms a contact piece 12 by notching the front lower edge and extends in the longitudinal direction. Push pieces 61.73 provided at the tips of the first and second levers 19.20 are inserted into the guide groove 22. First lever 19
is fixed to the boss portion 29 and has an arcuate protrusion 81 on the outer edge of its back. The lever 20 of Clause 2 is rotatably attached to the boss part 30, and is provided with an arc notch groove 84 into which a retaining piece 82 protruding from the boss part 30 can be inserted with a dowel. ing. The rear surface of the notched groove 84 contacts the front-striking retaining piece 82 at the reference position where the second lever 20 is tilted forward. The lever 20 of Bunsetsu 2 is provided with a locking part 25 having a relatively small protruding length on the rear surface and out of phase with the protruding part 81 in the counterclockwise direction at 43 in the figure. Further, the case 14 is provided with a locking tool 7 made of a plate body 7a that is biased forward by a spring. As shown in FIG. 10, the locking tool 7 engages with the locking portion 25 when the second lever 20 is tilted backward, and can maintain the stool state thereafter. Furthermore, the cough locking device 7 can slide into contact with the first lever 19 and is moved back by the protrusion 81 and separated from the locking portion 25 .

An inclined surface 82a is provided inside the engagement piece 82, and when the inclined surface 8'2a rotates counterclockwise,
The lock pin 89 provided in the case 14 is moved. As the lock pin 89 moves, it fits into a locking hole 90 provided in the first lever 19, and the first lever 19 can be locked in its forward tilted state.

Therefore, by operating the first operating body 3 that fits into the boss portion 29 and moving the first lever 19 1&, the push piece 6
1 presses the rear surface of the guide groove 22 and moves the lock 11 to the fully extended position iA.
9 to the open door position B (as shown in FIG. 9). Moreover, the control tool S can be turned on by opening the door. Also, by operating the second lever 20 on the side through which it has passed, the engagement piece 82 tilts the second lever 20 backward, and the locking tool 7 engages the locking portion 25 as shown in FIG. Can be held in a backward tilted position.

As a result, the lock lever 11 is locked in the incompletely protruding position C, and the control tool S continues ONL. Note that even if the second lever 20 is repeatedly operated, the same state is maintained. Note that since the notch groove 84 is provided, only the second operating body 4 can be returned to the standard state. Note that in this state, by rotating the second operating body 4 counterclockwise beyond the reference state, the lock pin 89 can lock the first operating body 3 as described above. In addition, when exiting, after operating the second operating body 4 to open the door, by operating the first operating body 3, the protrusion 81 causes the locking tool 7 to retreat as shown in FIG. It is separated from the locking part S1. As a result, the levers 19 and 20 of the first FA2 can return to their original states, and the lock rod 11 returns to its fully extended position, allowing the control tool S to be turned off. In this embodiment, even if the second operating body 4 is operated repeatedly, the lock rod 11 can be maintained at the incompletely protruding position B. Therefore, it is possible to prevent the lock rod 11 from alternately reciprocating between the fully extended position and the incompletely extended position iWc by repeatedly operating the second lever 20, as in the embodiment described above.
