Technical Field
[0001] The present disclosure relates to a transmission mechanism which can be assembled
to the gas cocks of the devices that are engaged in the ignition or combustion by
the liquefied petroleum gas (LPG) or natural gas (NG) source, without requiring any
additional piece.
[0002] In particular, the present disclosure relates to a transmission mechanism comprising
a switch-button shaft end which is dependent on the cock movement and which transmits
electrical energy to the ignition system by means of being mounted to the gas cocks
of all heating and cooking devices (household and industrial type furnaces, ovens,
combi boilers, etc.) operating with LPG and NG and having a manual or an electronic
control.
Prior Art
[0003] Nowadays, two types of switches, such as push-button and rotary switches, are used
in electronic or manually operated LPG or NG based heating and cooking devices (household
and industrial type furnaces, ovens, combi boilers, etc.), which provide electrical
energy to the ignition unit used for the burning of gas.
[0004] The push-button switches consist of a contact mechanism located in a body and a button
shaft to which said contact mechanism is actuated, and a piece(s) to move the vertical
movement of the button to the switch button, which is formed by the force exerted
on the gas cock shaft connected to the gas cock shaft. The most commonly used ones
of the said pieces and connections are the gasket-like structures which are mounted
on a channel opened to the gas cocks shaft. Another one is the model which is used
during mounting to a channel opened to the gas cock shaft, which does not use a gasket
or similar connection elements, and which works in a way that fixes the button shaft
to the cock shaft.
[0005] In the literature survey, the patent application numbered
TR 2001/00668 and titled as "An Electrical Switch for Gas Cocks" is found. The said invention regards an electrical switch for a lighter for gas
burners, which may be connected to a gas-supply cock, and its working principle. It
relates to the gas-supply cock of the invention having a maneuvering stem that is
free to slide and turn about its own axis within the gas-cock body to control gas
supply, the electrical switch, a shell that can be fixed to the gas-cock body to close
or to open the electrical circuit of the lighter, and that may be associated with
the second contact and close the second contact. However, due to the facts that it
is fixed to the button shaft and its movement is restricted, it has some drawbacks.
[0006] As a result, due to the above-mentioned drawbacks and the inadequacy of the existing
solutions, an improvement in the technical field has been required.
Brief Description of the Invention
[0007] The present disclosure relates to a transmission mechanism that meets the above-mentioned
requirements, eliminates all disadvantages and brings some additional advantages.
[0008] The main aim of the invention is to ensure the operation of the system without any
intermediary pieces between the gas cock and the switch. As a result, ease of installation
and price savings are provided.
[0009] Another aim of the invention is to present it to the user with simple and efficient
use.
[0010] Another aim of the invention is to present that the button shaft is not fixed to
the gas cock shaft, thereby providing unrestricted movement.
[0011] In order to fulfill the purposes described above, the invention is developed as a
transmission mechanism in which burning device comprising a gas cock combustion gas
is supplied, a switch providing ignition, a gas cook shaft which provides push movement
by force applied on it for ignition and a switch button shaft which provides the related
movement to be transferred to the switch, a gas cock shaft protrusion which is configured
on the gas cock shaft and enables the push movement applied on the gas cock shaft
to realize the contact so that the switch is actuated by the switch button shaft,
a switch button shaft end formed on the switch button shaft which provides contact
by transferring the push movement taken from the gas cock shaft through the gas cock
shaft protrusion without the need for fixing to mentioned gas cock shaft.

Detailed Description of the Invention
[0014] In this detailed description, the transmission mechanism is explained only for a
better understanding of the invention subject matter and without any restrictive effect.
[0015] Figure 1 shows the perspective view and assembly elements. The invention is developed
for the push-button switches models. The invention is, in its simplest form, a transmission
mechanism in which burning device comprising a gas cock (1) combustion gas is supplied,
a switch (2) providing ignition, a gas cook shaft (3) which provides push movement
by force applied on it for ignition and a switch button shaft (5) which provides the
related movement to be transferred to the switch (2), a gas cock shaft protrusion
(4) which is configured on the gas cock shaft (3) and enables the push movement applied
on the gas cock shaft (3) to realize the contact so that the switch is actuated by
the switch button shaft (5) and a switch button shaft end (6) formed on the switch
button shaft (5) which provides contact by transferring the push movement taken from
the gas cock shaft (3) through the gas cock shaft protrusion (4) without the need
for fixing to mentioned gas cock shaft (3).
[0016] The transmission mechanism of the invention's subject matter is mounted on the gas
cock (1). The switch (2) is connected to the body of the gas cock (1). The transmission
mechanism is comprising of a contact mechanism located in the said switch (2), switch
button shaft (5) in which enables movement of mentioned contact mechanism and the
pieces that are mounted on the gas cock shaft (3) which enables the button shaft (5)
to move and only the vertical movement of the gas cock shaft (3) is transferred to
the switch button shaft (5) in the push direction.
[0017] As shown in Figure 2, there is a gas cock shaft protrusion (4) positioned on the
gas cock shaft (3). The transmission of force in the vertical direction can be achieved
due to the distance of the switch button shaft end (6) to the gas cock shaft (3) is
being smaller than the length of the gas cock shaft protrusion (4). As a result of
the said mounting method, the movement of the gas cock shaft (3) on the vertical axis
is ensured only in the direction of the movement axis to contact the curved end of
switch button shaft end (6). Thus, the movement applied on the vertical axis is transmitted
to the switch (2) via the switch button shaft end (6) and is contacted with the contact
mechanism located in the switch (2), thereby igniting the gas.
[0018] The switch button shaft end (6), the gas cock shaft (3) which are contained by the
switch button shaft (5), and the gas cock shaft protrusion (4) are not fixed to each
other. The gas cock shaft (3) is independent of rotational motion. In the push direction
of the vertical movement, the gas cock shaft (3) is independent as the space between
the gas button shaft protrusion (4) and the curve end of the switch button shaft end
(6). The gas cock shaft (3) is moving along with the motion formed after the push
force in the vertical direction. The gas cock shaft (3) is completely independent
in the opposite direction of the vertical movement. In the transmission mechanism
of the invention, due to the fact that the switch button shaft (5) is not fixed to
the gas cock shaft (3), the unrestricted movement is provided. The switch button shaft
end (6) along with the switch button shaft (5) in which it is positioned on, is pushed
back to its initial position following the force applied after the ignition has been
disappeared. The element that provides this is the spring (7) within the switch (2).
The mentioned spring (7) is shown in Figure-3.
