A bolt engages with and extends through the nut to have an end thereof engaging and abutting an end of the operation sleeve, whereby rotation of the bolt with respect to the nut seat applies a pushing force to the rotation sleeve, which in turn causes the curved frame to rotate, bringing the roller into engagement with the ground and further adjusting the distance between the ground and the stove bottom. | 02-18-2010 |
20100216080 | LIGHT-SPOT-INDICATION GAS RANGE SWITCH DEVICE - A light-spot-indication gas range switch device includes a switch knob seat to which an LED is mounted. A cam ring is fixed to a rotary shaft of a gas valve in such a way that a bulge section of an outer circumference of the cam ring corresponds to a rotation range within which a rotary switch knob opens the gas valve and a truncated section of the outer circumference corresponds to a location where the gas valve is closed. The micro-switch support bracket supports a micro-switch and is arranged in such a way that a switching tab of the micro-switch engages the outer circumference of the cam ring. When the rotary switch knob is turned to set up a range flame, the micro-switch is triggered and the LED is powered by an electrical source to give off light indicating the turning on of the gas range switch device. | 08-26-2010 |
