TECHNICAL FIELD
The present invention concerns the rotary push button switch system for all types of gas-burning stoves and heaters, including ovens and cookers, which is used in accompany with gas-cocks and applies electricity energy to ignition system.
In particular way, the invention refers to a rotary push button switch system, which is used on gas-cocks to create arc-form sparks with up-and-down linear movement to ignite the gas, which activates lighting, fan, or another ignition element within the stove-oven by rotational movement, and which enables on-off operation with two separate energy systems.
Current State of Art
All types of gas-burning stoves, cookers, and similar products need a heat-arc energy to ignite the gas and create flame when gas-flow to system is initiated by moving gas-cock shaft. There are ignition transformers used to obtain this energy. Contacts, which come into active-contact with the effect of rotation or linear movement of gas-cock shaft and provide supply voltage for the said ignition transformers, and push or rotary switch systems, which provide electric current to create an arc-shaped spark, are used.
In the current state of art, the push or rotary switch systems are activated by downward or rotational movement of gas-cock shaft to allow electric current to the ignition transformer when gas flow to the system starts, which use the spark generated by transformer only for the purpose of igniting the supplied gas. In order to activate other electronic or mechanical applications such as lighting, fans, etc in the rotary or push type switch systems connected to the gas-cock shaft to ignite the gas in gas-burning cookers and heaters, various sensors such as thermocouple, buzzer, and complicated circuit boards for such sensors should be used, which will increase the cost. For this reason, in addition to the increase in part costs during the manufacturing phase, additional control and production processes are also needed, which implies huge production costs. In the current state of art, much felt the need for a rotary push button switch system that enables to eliminate this situation.
As a result, existence of above-mentioned problems and inadequacy of existing solutions made it necessary to make an improvement in the relevant technical field.

DETAILED DESCRIPTION OF EMBODIMENTS
Preferred alternatives of the rotary push button switch system are explained in this detailed description only for a better understanding of the subject and without posing any limiting effect.
FIG. 1a represents various separate components that, when assembled, constitute rotary push button switch system in accordance with the invention. With reference to FIG. 1a, rotary push button switch system, in its most basic form, comprises a body (10) connected to the gas cock shaft; a hub (20), which moves up-and-down in conjunction with linear movement of gas-cock shaft in the center of body (10) and by being positioned on the lugs (22) extending downwards from the bottom and ensures ignition of gas through contact of the washer contact terminal (40) onto push contact terminal-1 (50) and push contact terminal-2 (60) inside body (10) with the thrust applied onto washer contact terminal (40) by means of a spring (30) and which, at the same time, also ensures operation of lighting, fan or other ignition element inside the furnace-cooker through the contact of flexible rotary contact terminal (80) inside the body (10) to the rotary contact terminal (70) connected to the lighting, fan or other ignition element inside the oven-cooker by means of the cam (21) in the upper part of the gas-cock shaft.
The body (10) constitutes main structure of the rotary push button switch system, which is the subject matter of the invention. There are slots (11) formed on inner surface of the body (10), cable conduits (12) formed on it (10), and locating lugs (13) extending downwards on its lower surface.
The hub (20), which rotates or moves up-and-down linearly in order to control operating regime depending on the movement of the gas-cock shaft of the rotary push button switch system, is positioned in the center of the body (10).
As seen in FIG. 2a and FIG. 2b, there is a semicircular intrusion-shaped cam (21) on the upper part of the hub (20), lugs (22) extending downwards from the lower part of the hub (20), and a protrusion (23) extending upwards on it (20). As seen in FIG. 3, a cylindrical spring (30) and a circular washer contact terminal (40) are positioned on these lugs (22). The spring (30) applies thrust onto washer contact terminal (40) and ensures the washer contact terminal (40) to rest on the lugs.
As seen in FIG. 4 and FIG. 5, push contact terminal-1 (50) and push contact terminal-2 (60) are placed reciprocally in the slots (11) formed inside the body (10). Said push contact terminal-1 (50) and push contact terminal-2 (60) are interconnected via the cables placed in the cable conduits (12) formed on the body (10) and ensures initiation of electric current to ignite the gas via contact of washer contact terminal (40) driven by up-and-down linear movement of the hub (20). The washer contact terminal (40), which moves downwards by being driven by the linear movement of the hub (20) in conjunction with linear movement of the gas-cock shaft, presses evenly on the push contact terminal-1 (50) and the push contact terminal-2 (60) thanks to its circular form.
As seen in FIG. 6, the rotary contact terminal (70) and flexible rotary contact terminal (80) which contacts rotary contact terminal (70) are located in the slots (11) formed reciprocally in the body (10) for the operation of lighting, fan or other ignition element inside the furnace-stove.
The rotary contact terminal (70) is connected to the lighting, fan or other ignition element inside the furnace-oven via the cables placed in the cable conduits (12) formed on the body (10). The rotary flexible contact terminal (80), on the other hand, is connected with the cables placed in the cable conduits (12) formed on the body (10) in order to transmit electric current for the operation of the lighting, fan or other ignition element in the furnace-stove and it flexes by the thrust applied by the cam (21) on the hub (20) with rotational movement of the hub (20) and contacts rotary contact terminal (70) as seen in FIG. 7 and ensures transmission of electric current.
As can be seen in FIG. 8 and FIG. 9, a cover (90) suitable to the outer form of the body (10) and which encloses its entire circumference is put on the body (10) in order to prevent entry of dust and water into the body (10). As seen in FIG. 10, an intrusion (91) is formed on the inner surface of the cover (90) in accordance with the form of protrusion (23) on the hub (20). Thus, when the cover (90) is closed on the body (10), the protrusion (23) on the hub (20) is positioned in the intrusion (91) on the inner surface of the cover (90) and entry of dust is prevented by providing a sealing between the hub (20) and the cover (90).
The body (10) is fixed to the gas-cock by locking it by means of locating lugs (13) extending downwards on its lower surface.
The operating principle of rotary push button switch system seen in FIG. 11 is as follows; When pressed on the gas-cock shaft the hub (20) seen in FIG. 12a moves linearly downwards inside the body (10). In the rotary push button switch system, the washer contact terminal (40) which rests on the lugs (22) underneath the hub (20) by means of a spring (30) contacts on the push contact terminal-1 (50) and push contact terminal-2 (60) as seen in FIG. 12b and ensures ignition of gas with the gas flow by starting arc formation process.
With the rotation of the gas-cock shaft, the cam (21) in the upper part of the hub (20) applies a thrust onto rotary flexible contact terminal (80), which, in turn, flexes and contacts with rotary contact terminal (70). When electric current is transmitted to rotary contact terminal (70), the lighting, fan or other ignition element in the furnace-cooker is ensured to operate.
