Definitions

  • This invention has been designed for gas burners working with flame.
  • This tap serves the function of cutting the flow of gas automatically and prevents serious dangers in the event that the flame goes off or the flame is interrupted. It provides additional security for furnaces or similar burning systems having a standard simple system. Basically, transforms the vertical movement given ahead to horizontal movement. During the forward movement of the axle (1), the axle (1) shall also be performing a rotational movement and the gas that is taken in with the gas tap through the entry connection (2) is given to the back pipe connection (3).
  • This tap functions as an opening and closing valve within the burning system. When the faucet is examined from above ( Figure 2 ) the fact that the tap is of "Y" type saves space.
  • the tap works with the same principle as in other furnaces used on the kitchen bench with security function.
  • the system in this invention also functions in the same principle as in other security furnaces used on kitchen benches.
  • the systems functions with the transformation of the movement given in a vertical manner to horizontal and in these systems transmission of a movement with 90° has been taken as a basis.
  • the movement of the system is quite complex and there is a difficulty of manufacturing for the components.
  • the tap is quite heavier and larger than others that have similar features. This also increases the weight, size and cost of the furnace.
  • the patent with no DE19616797 registered in the name IMIT SPA (IT) is concerning safety type gas cock to be used in flame gas furnace.
  • This invention is rather complex in structure. Two pieces sheet inside is joined and placed into cock body. After placing it into cock body, the cock body is closed with a stopper. However, in our invention, it is not required to do it.
  • Such sheet parts placed into safety gas cock mentioned in this patent with no DE19616797 increase the size and weight of cook too much. In our invention, such size and weight is smaller and lighter in comparison with the mentioned DE19616797 .
  • a pushing knob (6) has been designed as an accessory, which shall be fixed to the cover of the tap (4) in order for it to complete the circuit to a micro-switch (5).
  • a micro-switch (5) can be inserted on this tap and it has been designed in a manner to be used in this way ( Figure 2 ).
  • thermo-magnet electro-magnet
  • point or surface contact has been achieved between the pin (8) inside the body (7) and the guiding pin (9) that guides it and in this manner; it is made possible that the action is transferred from horizontal to vertical during the point of press to the axle (1).
  • the tip angle (10) of the first part of the guiding pin (9a) is between 70° and 130°. This provides an opportunity for the guiding pin (9) to move more when wanted.
  • the axle (1) provides an opportunity to increase or decrease the movement of the (tap control handle) forward and backwards and different knobs or switch models to be used.
  • Another new feature of the invention is the fact that their standard height has been decreased from 40 mm to 30 mm. In this invention, the height could be pulled even further down up to 22-27 mm. This provides an opportunity to construct thinner furnaces and stoves that can be used on kitchen benches. This height is the distance from the lowest point of the body (21) until the highest point (22).
  • Another benefit of the invention is that it is more compact as a consequence of its geometric shape.
  • the design that resembles the letter "Y" when looked from above ( Figure 2 ) is made of a gas entrance connection (2), a gas exit (3) and an arm (15) incorporating a thermo-magnetic valve (14) in itself.
  • the fact that this shape can be changed provides an opportunity for more different designs to be made in this product.
  • the arm (15) incorporating the thermo-magnet in its structure can be placed in any direction in manner that it shall be max ⁇ 90° to the axis of A-A.
  • the gas exit mouth (3) can also be located in a position that is in harmony with the angular specifications given above.
  • the ability to make connections in different manners in this respect shall also provide opportunities for stoves and furnaces to be made with new designs and shapes.
  • the way of operation of the going out security tap of the invention is in this manner; the axle (1) is moved forward and a vertical movement is achieved in the pushing pin (8) along with the axle. During the vertical movement, the pushing pin hits the guiding pin (9) and forces the guiding pin(9) to horizontal movement. Since the system is a closed circuit the guiding pin (9), presses the thermo magnetic valve(14) and provides an opportunity for the gas transfer channel (11) to be opened. While the axle(1) is in the front position, it makes the conic male (12) assembled inside the body (7) revolve along with the axle(1).
  • the gas that passes through the gas transfer channel (11) passed through the clover shaped wings (13) fixed firmly on the guiding pin(9) and fills inside the male (12) and the gas is transferred into the gas exit(3) along with a revolving movement.
  • the gas sent from the exit to the burning system starts burning with the electricity signal sent to the sparking plug in the back system from the switch.
  • the low electrical voltage produced by the thermo element connected to the system causes the thermo magnet to be pulled off and the system to operate.
  • the electrical current coming to the thermo magnet will be interrupted and hence the gas shall be shut off and the system will turn itself off.
  • the guiding pin(9) shall be set free.
  • the forward movement of the guiding pin (9) shall be through the help of the pin (8) and its backward movement shall be with the own spring of the thermo magnet. There is no need to direct the movement with additional parts or systems.
  • the shape of the claw does not impose any restriction. Shapes that shall provide an opportunity for sufficient amount of gas may be used. The important thing is to provide the function of bedding (11) and sufficient gas passage at the same time.
  • the micro-switch(5) can be assembled easily through the claws (34) on the cover that has been designed and thanks to the design of the cover(4), it does not allow any false assembling, coming out or turning.
  • the direction for opening gas is counter clockwise and the direction of closing the gas is clockwise.
  • This revolving angle can be adjusted for a value between 0° and 260°.
  • the angles that are used as a standard are 0°-160° and 0°-210°. Checking the flame will be easier for higher revolving angles.
  • the tap When turned clockwise, the tap shall be closed at 0°.
  • the direction of turning is provided through the help of the claws (16) inside the cover (4).
  • the cover When the cover is placed in a reversed manner, it shall prevent the axle(1) from turning and shall not allow the gas to pass. This has been taken into consideration during the design of the cover(4) and the cover(4) has been designed in such a manner that assembling it wrong is impossible.
  • the magnet record cover (45) and the record (20) may show differentiations depending on the magnet choice of the user.
  • the system also provides an opportunity for the use of the electro magnet as well depending on technological developments.
  • the channel (43) inside the male (12) can be closed and an opportunity can be provided for the tap to have a security going out feature by taking out the pin (8), guiding pin (9), plastic gasket (18) and the stamp (36).
  • the body (7) may be made of brass or any other material or an alloy of metals of equivalent value that is resistant to heat and gas.
  • the weight of the body (7) has been designed to be much lighter than its equivalents. The equivalents are on the average 100 grams and this weight has been decreased to 60 grams in this design.
  • the angle between the A-axis and the axle(1) in the tap body (7) with a security going out feature for stoves or furnaces used on the kitchen benches is 90° in all other models. However, in this invention referred to, this angle has been characterized to be between 70° and 110°. When this arm is around 70° and 110°, the angle of the pin with number (9) shall change and hence, the angle of the pin should also be changed depending on the position of the angle of the arm(15).
  • the inner part of the body has been designed in a hollow manner and has been manufactured in a single piece.
  • Said body comprises the gas entry(2) of the body and the gas exit (3) both in the same plane, the arm (40) with the axle and other components tied to it which is 90° perpendicular to these two entries and exits that realizes the pushing-revolving-gas passage functions as well as the arms that are 45° to the gas entry and gas exit and also incorporating a thermo-magnetic valve (14).
  • the angle of 45° has been chosen in a manner that shall allow the system to be in the most compact form possible. With this angle, it has become quite smaller than its equivalents.
  • the fact that the body is small has made the system lighter. Furthermore, the body that is small also provides ease of manufacturing.
