A SYSTEM AND A METHOD FOR AUTOMATICALLY TURNING OFF OF THE SUPPLY OF GAS OF A CYLINDER THROUGH A TIMED CONTROL MEANS

FIELD OF INVENTION

The present invention relates to a system for automatically turning off the supply of gas without employing electrical or electronic devices. More particularly, the present invention relates to a system and method of automatically turning off the supply of gas of a cylinder to the gas stove through a timed control means.

PRIOR ART OF THE INVENTION

Now a day's gas stove is a popular cooking appliance used in residential and commercial applications. Most of the gas stoves are not equipped with safety devices. At times, it is very difficult to remember to switch off the regulator connected to the gas stove when not in use. In these situations the LPG gas may leak and lead to cause fire hazards. Also, the consumption of the LPG gas is increasing these days and there is a need for reduction of the same. For the reason of public safety and regulating the usage of gas, it is necessary to provide a control device for controlling the use of gas and to provide security. Existing systems providing controls for the supply of gas include use of a thermoelectric safety shut-off valve requiring an electricity supply to operate controller. Another, device uses a gas grill with an automatic shut-off valve controlled by a dynamic activity sensor. This works when an activity sensor senses the activity with a motion detector to avoid fire hazard and/or wasting of fuel. The uses an adjustable timer to activate an automatic gas shut-off device to cut-off gas supply after no motion has been detected for a preselected time period. Also the adjustable time controlled valve can be turned on merely by turning a knob. A child could therefore inadvertently turn on the gas supply simply by turning a knob.

These systems use electrical and electronic components to controlling which is adding cost to the overall system. Such kind of systems has a risk of explosion due to gas leaks and is prone to linger, especially when using gas appliances and equipment even if the lock does not lock the valve in the middle of any inexperienced operation, such as the elderly or children.

Therefore there is a need to develop a timed control device providing an effective control, processing and avoiding danger of explosion or excess use of resources when the regulator of the cylinder is left open manually. This timed control device operated to automatically on/off the supply of gas to the gas stove when a pre-set time is reached.

For ease of understanding the invention and clarity a 'timed control means' is referred to herein as a 'timer', a 'cylindrical structure' is referred to herein as a 'cylinder' and a 'motor means with a springy element' is referred to herein as a 'spring motor' in the following description with reference to the drawings. Referring to FIG. 1, depicting a cross sectional view of a working model 100 of the system according to the present invention. The system comprises two main parts an I- shaped housing 102 and a cylinder 110 where an I-shaped housing 102 is connected to the shroud walls 144 of the cylinder 110. The housing 102 consists of three sections i.e. upper section 104, middle section 106 and bottom section 108 each employing elements for attaining the automatic off of the gas supply to the gas stove from the cylinder 110 enabling the safety of the consumers.

The upper section 104 of the housing 102 consists of a timer 114 which is connected to a drive wheel 112 through a rod as shown in the FIG. 1. When there is no gas supply, there is no operation of the timer 114 which does not employ any electrical and electronic devices for automatic off of the supply of gas from the cylinder 110 to the gas stove (not shown). The cylinder 110 comprises a tank 140 of longitudinal in shape accommodating gas such as LPG or LP gas and three shroud walls 144 supported with a circular ring 138 on the top of these shroud walls 144, where there is provided with a regulator 142 arrangement placed between the circular ring 138 and at the center of the three shroud walls 144 with a knob pin 136 is attached to the regulator 142.

The operation of the timer 114 starts only when the knob pin 136 of the regulator 142 is switched ON, the timer 114 starts counting the time till the pre-set time is reached to automatically OFF the gas supply. The drive wheel 112 placed on the top of the timer 114 is provided with a hollow space at its center to accommodate the string 116 provided in the middle section 106 of the housing 102, where one end of the string 116 is connected to the driving wheel 112 and the other end is connected to a switch 118 placed at the bottom of the middle section 106. The string 118 capable of rolling on to the hollow space provided at the center of the driving wheel 112.

The other end of the string 118 is connected to the a long pin 120 provided in the bottom section 108 of the housing 102, where the long pin 120 is further connected to a shaft 126 of the spring motor 128 which in turn connected to a gear wheel 122. Another support pin 124 arranged on the shaft 126 at the center of the gear wheel 122 supporting the movement and rotation of the gear wheel. The bottom section 108 also comprises of an extension plate 130 with holes on which U-shaped clamps 152 are inserted. Further the gear wheel 122 is connected to the knob pin 136 of the regulator 142 through a chain 134 that can be rolled on to the gear wheel 122 to turn OFF the knob pin 136 of the regulator 142 when rotated. The regulator 142 is firmly balanced in position by a C-clamp 146 with a holding pin 148 connected to the one of the shroud wall 144 of the cylinder 110 through nuts and bolts. The bottom end of the C-clamp 146 is further connected to the U-clamps 152 further fixed to the extension plate 130 of the housing 102 through Y-shaped bolts 150 to one of the shroud walls 144. When there is supply of gas through cylinder 110 by turning ON the knob pin 136 of the regulator 142, the timer 114 starts counting time till the pre-set time is reached. Then the string 116 placed in the middle section 106 is driven by the driving wheel 112 to roll on to it in the hollow space provided which will create a tension in the string 116. This action pulls the switch 118 towards the timer 114 and the long pin 120 which rests on the switch 118 goes downwards allowing the gear wheel 122 to rotate in the reverse direction. The chain 134 connected to the gear wheel 122 is made to pull completely in backward direction to turn OFF the knob pin 136 of the regulator 142. The gear wheel 122 is interconnected to the spring motor 128 through the shaft 126. The timer 114 used in the present system do not employ any electrical or electronic devices avoiding the additional cost to the system. The upper section 104, middle section 106 and the bottom section 108 of the housing 102 are arranged in a manner to form an I-shaped structure. Further, the arrangement of each element of the working model 100 as shown in the FIG. 1 is shown in the preceding drawings from FIG. 2 to FIG. 8.
