PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention

FIELD OF INVENTION
This invention relates to a novel safety arrangement for Iron
BACKGROUND OF INVENTION
The ironing process is to remove wrinkles on the cloth after washing with the help of iron device. The ironing is basically pressing the cloth against an iron device heated with a prescribed temperature depend on the cloth to be pressed. The conventional iron devices have features like steaming while ironing, automatic power cut-off after a particular time, when the iron reaches a particular temperature range. During the process of ironing, there are instances that power goes off or the user gets attention for a different action and forgets to switch off the device. This is dangerous in terms of overheating the iron and hence catching fire with the cloth being overheated continuously unattended. In the prior art, there are various devices available such as keeping the iron over a stand made of non-conducting or insulating material manually. The Japanese patent 9075600 discloses an invention having a motor fan for cooling purpose to be activated during the standby mode and hence the covering part is cooled. This conventional ironing dangers have not been addressed so far. However, the typical problem of unattended iron during ironing, in the midst of power off, and subsequent power on, has not been addressed. The present invention discloses an arrangement provided with the iron device to overcome the problem associated with the prior art.
OBJECTS OF INVENTION
An object of the invention is to provide a novel feature on the iron so as to protect both the cloth overheating and subsequent burning as well as the preventing of catching fire.


Another object of the invention is to provide a safety feature in the iron, which will prevent direct contact of iron with that of the cloth being ironed, when it is unattended for a reasonable prescribed time.
Another object of the invention is to provide a servo motor controlled elliptical wheel which will act on the temperature range sensor input, to prevent the overheating of the cloth.
Another object of the invention is to provide a timer based control to the elliptical wheel to prevent direct contact of the iron to the cloth being ironed.
Another object of the invention is to provide a servo motor control which will work based on the input signal received from temperature sensor or timer or any other means.
Another object of the invention is to provide an elliptical wheel which will rotate to a prescribed degree so that the extended off-set radius circle comes into contact with the cloth being ironed or over the surface being ironed, so as to prevent a direct contact with these by the over heating iron.
Another object of the invention is to provide a non-contacting heating surface of the iron by positing the iron with elliptical wheel and rear end non-ironing surface which will stand on its own.


Another object of the invention is to provide an iron with a undercut and a leg having
a radius surface which will facilitate the iron to move for a shorter distance without
friction.
DETAILED DESCRIPTION OF THE INVENTION
This invention addresses the requirement of non-contacting of heating iron to that of cloth being ironed. An elliptical wheel having its centre offset with a prescribed distance so that when it rotates to an amount equal to the offset centre distance, the iron will start elevating itself from the surface or the cloth thereby preventing the direct contact of the iron. The elliptical off-centred wheel is operated by a servo motor mounted inside the iron. The servo motor rotated to a particular prescribed degree upon receiving signal from inputs. The inputs received may be from temperature sensor control or the timer control or any other means. The temperature sensor activates the servomotor when it exceeds a particular temperature. The iron may also be activated by timer for which time can be set manually and upon reaching the time, this will feed input signal to the servo motor.
Upon receiving the signal, the elliptical wheel rotates so that the off-centre wheel rotates thereby moves the iron to a reasonable distance forward as well as elevates the iron from the direct contact of the cloth or the surface. For this purpose, it is also designed to have the rear end of the iron where an undercut and a small leg is provided and the leg will have a concave round surface finish. This feature prevents the overheating iron being in direct contact with the cloth when it is unattended or when the power resumes in the absence of the user.


In accordance to the present invention, a novel feature on the iron is provided to protect the cloth overheating and subsequent burning as well as the preventing of catching fire.
In accordance to the present invention, a safety feature in the iron is provided to prevent direct contact of iron with that of the cloth being ironed, when it is unattended for a reasonable prescribed time.
In accordance to the present invention, a servo motor is provided to control elliptical wheel which will act on the temperature range sensor input, to prevent the overheating of the cloth.
In accordance to the present invention, a timer is provided to control the elliptical wheel to prevent direct contact of the iron to the cloth being ironed.
In accordance to the present invention, a servo motor control is provide to work based on the input signal received from temperature sensor or timer or any other means.
In accordance to the present invention, an elliptical wheel is to provided to rotate to a prescribed degree so that the extended off-set radius circle comes into contact with the cloth being ironed or over the surface being ironed, so as to prevent a direct contact with these by the over heating iron.


In accordance to the present invention, a non-contacting heating surface of the iron is positioned with the help of an elliptical wheel and rear end non-ironing surface which will stand on its own.
In accordance to the present invention, the rear end of the iron is provided with a undercut and a leg having a radius surface which will facilitate the iron to move for a shorter distance without friction.
