[Industrial applications]

 This invention is a timer-integrated closure that automatically locks the valve or stopper by using it on a valve or stopper of a gas table, bath water heater, bath water, oil stove equipment, etc. for a limited time. It relates to the device.

[0002]

[Prior art]

 The conventional capping device using a mainspring timer is complicated, and there is concern about its function and safety in terms of technology, so it is rarely used at present. Also, most of them are limited to each device, and few are available for each device. In addition, many timers are not integrated with valves and stoppers, which requires a large space, making it difficult to install with equipment with limited space or water taps that do not have space. The one with the automatic capping mechanism was complicated and the structure was troublesome. At present, a timer is often used for switches in electrical equipment, but in order to attach an electrical timer to something other than electrical equipment, it is necessary to use batteries, household power supplies, etc. It becomes an obstacle when it becomes necessary, and it causes pollution because it accelerates the consumption of energy. Furthermore, it is unsuitable for water taps.

[0003]

[Problems to be solved by the device]

 Except for its drawbacks, the present invention uses an energy-saving and pollution-free spring spring, an automatic capping device with a cooking timer for gas tables, a timer automatic capping device for bath taps and gas water heaters, a timer automatic extinguishing device for oil stoves, etc. , An attempt to develop a timer-integrated automatic capping device.

[0004]

[Means for Solving the Problems]

 The structure will be described mainly for the case of a gas table with counterclockwise opening and clockwise opening and a full opening angle of 130 degrees. (A) The knob 2 is pushed into one end of the convex shape of the pipe shaft 1 and the memory plate is inserted. 3, the spring spring 4, the gear 5, the roller washer 6 are provided in this order, and the gear 7 is attached to the other end. (B) Base plates 8, 9 and 10 are provided on the outside of the mainspring 4, between the gear 5 and the roller washer 6, and at various parts on the outer side of the roller washer 6 and fixed by the pipe columns 11, 12 and 13. (C) The valve shaft 14 is pushed into the pipe shaft 1, the knob 15 is attached to one end of the convex shape, and the gear 16 having teeth at the opening angle is provided between the gear 7 and the base plate 10. (D) The base plate 8 of the timer portion is provided with double gears 17, 18, and 19, a connecting rod 20 and a reversing plate 21, which are connected to the gear 5 in order, and they are attached by columns. A spring spring 22 is provided on the column of the reversing plate 21. (E) The stopper mechanism is provided with a movable C-shaped roller guide 23 with one end for guiding the roller washer 6 on the base plate 9, and a spring 28 and a C-shaped roller for safety on the other end. A leaf spring 33 is provided on a part of the base plate 9 outside the guide 23. Further, a stopper pin 29 for keeping the C-shaped roller guide 23 open and springs 30, 31, 32 of the stopper mechanism are provided. The projecting and retracting operations of the stopper pin 29 are performed by the repulsive force of the springs 31 and 32 by pressing or releasing the spring 30 for the stopper pin by the projection of the roller washer 6. (F) The base plate 10 is provided with a gear 24 connected to the gear 16. Further, a gear 25 is provided which is connected to the gear 7 and the gear 24 and is inclined and separated when the C-shaped roller guide 23 is opened and closed. (G) When changing the rotation direction, the gear 16 connected to the gear 24 is slightly separated, and the gear 26 connected to both is provided. (H) For push-plug devices, a gear 27 with a straight screw bearing having teeth at the opening angle is provided instead of the gear 16 provided on the valve shaft 14.

[0005]

[Action]

 (B) Since the present invention has such a structure, the C-shaped roller guide 23 is closed by the notch for closing operation of the roller washer 6 when not in use as shown in FIG. Connected with. Further, since the valve shaft 14 has completed the closing operation, the gear 16 that is always connected to the gear 24 for opening the counterclockwise opening or the gear 26 for opening the clockwise rotation has completed the toothed portion of the opening angle. Then, the connecting portion becomes a toothless portion. Therefore, even if the pipe shaft 1 of the timer is being closed, the valve shaft 14 is already in the completely closed state, and the operation is ended to wait for the operation of the pipe shaft 1 to be ended. However, when trying to open the valve shaft 14 in order to use the rotary opening / closing device from this state, the toothed portion of the gear 16 meshes with the gear 24 or 26, and the pipe shaft 1 works together with the timer. Since the operation of the valve shaft 14 is suppressed by being connected to the pipe shaft 1 and the mainspring 4 of the above, and a halfway opening of the roller washer 6 within the notch for the closing operation of the roller washer, the closing mechanism works. It becomes a safety device. Further, if the roller washer 6 is forcibly opened beyond the notch for closing operation, the timer is set. At this time, the C-shaped roller guide 23 is pushed open and the gear 25 inclines and is disconnected from the gear 7, so that the valve shaft 14 becomes free. Therefore, if the gas table does not ignite well, the valve shaft 14 can be manually closed by the knob 15 of the valve shaft. In the case of a push-plug device, the gear 16 functions similarly, but the gear 16 needs to be replaced with a gear 27 having a linear screw bearing. (B) When using the device, rotate the knob 2 of the timer to the free point as shown in Fig. 2B, the pipe shaft 1 will rotate, and the roller washer 6 that interlocks with it will push open the C-shaped roller guide 23, and The gear 25 interlocking with it is tilted and separated from the gear 7, leaving the valve shaft 14 free, and the stopper pin 29 protruding to keep the C-shaped roller guide 23 open. (C) Therefore, as shown in c of FIG. 2, the valve shaft 14 can be put into a free state and the opening and closing of the valve can be manually operated freely. Therefore, when the timer is not necessary, the knob 15 pushed into the tip of the valve shaft 14 can be manually operated in all cases. (D) When the timer is set as shown in FIG. 2, the stopper bar 30 is released, and the stopper pin 29 is submerged in the base plate 9. (E) Therefore, as shown in E of FIG. 2, when the guide time of the C-shaped roller guide 23 reaches the incision point for the closing operation of the roller washer 6 after the set time of the timer ends, the C-shaped corogite 23 is freely closed. Then, the gear 25 is connected to the gears 7 and 24. At this time, due to the closing movement of the C-shaped roller guide 23, the double gear 18, which is indirectly connected to the gear 5 of the timer mechanism, is tilted and opened, the clock function of the timer is stopped, and the mainspring 4 is released, and the pipe shaft. 1 and the valve shaft 14, the gear 5, the roller washer 6, the gear 7, and the gear 16 or 27 that are interlocked with them rotate at a stroke to perform the closing operation. (F) When the timer is operated, the gear 18 is tilted by the opening and closing movement of the C-shaped roller guide 23, or it is connected to or separated from the adjacent gear 19 by being perpendicular to the base plates 8 and 9. The mainspring 4 is released, or is suppressed when the timer function starts, and stops and operates. (G) As the spring spring 4 of the timer section is released, each mechanism operates to rotate or linearly move the valve shaft 14 to operate the capping mechanism. However, when the valve shaft 14 is completely capped, the gear 16 or 27 The meshing part with the gear 24 or 26 connected to it becomes a toothless part, and even if the pipe shaft 1 of the timer is in operation, the gear 24 or 26 idles and only the pipe shaft 1 rotates to the end point. Therefore, even when the timings of the pipe shaft 1 and the valve shaft 14 of the timer do not meet, they always function without any problem, and the opening angle can be freely selected when using the device. (H) Since the gear 24 changes the rotation of the gear 16 connected to it, it becomes an automatic capping device for the counterclockwise opening device, and when the gear 24 and the gear 16 are slightly separated and the gear 26 connecting them is provided, the gear 24 rotates again. Instead, it becomes an automatic capping device for clockwise opening caps. (I) Further, when the gear 16 provided on the valve shaft 14 is replaced with a gear 27 with a straight-traveling screw bearing, an automatic capping device for a push plug is obtained.

[0006]

【Example】

 In implementation, (a) When the gear 16 provided on the rotary on-off valve shaft 14 is replaced with a gear 27 with a screw bearing for straight travel, an automatic capping timer for a push plug device that operates straight ahead is provided. (B) When the gear 24 connected to the gear 16 is slightly separated and the gear 26 connected to each of them is provided, an automatic capping timer for a clockwise uncapping device is provided. (C) By changing the diameter of the gears 7 and 16 or 27 and the angle of the toothless portion, the rotation angle and the straight movement width of the valve shaft 14 can be changed as necessary. . (D) The base plates 8, 9 and 10 and the base plates 8, 9 and 10 and the knobs 2 and 15, the valve shaft 14 and the pipe shaft 1 can be attached to the base plate 8, 9 and 10 by changing the structures and dimensions of the base plates 8, 9 and 10. You can put it on either. (E) The spring 28 for closing the C-shaped roller guide 23 may be omitted, and only the leaf spring 33 may be used. Further, a brake for stopping the reversal phenomenon of the valve shaft 14 for preventing gear noise at the time of the closing operation, a music box for notifying the end may be provided.
