THE DETAILED DESCRIPTION OF THE INVENTION

In this detailed explanation, the invented subject matter is explained with figures in order to make the subject more understandable without forming any restrictive effect. As can be seen in Figure 1, the cooker (10) which the subject matter invention is applied comprises at least one burner (15) which is a gaseous heating element and at least one spark plug (17) positioned preferably near each burner (15) in order for the gas coming from the burner (15) to be flamed. In a representative embodiment of the invention, said cooker (10) can be selected as any kind of gaseous oven stove and stove having at least one burner or oven which is in mixed type comprising electrical, induction or other heating elements which is combined with this burner. With reference to Figure 2, in a representative application of the invention, the gas transmission system in the interior components of the cooker (10) comprises a main gas pipe (11) and/or gas collector pipe (13). At the end of the gas transmission system, there is at least one burner (15) where the burning process is realized where the gas coming from the pipes (11, 13) burns. In order to realize the burning process, an ignition system is needed. In a representative embodiment of the invention, the ignition system comprises at least one spark plug (17) and at least one lighter transformer (19) which provides a spark for the spark plug. In a representative embodiment, said lighter transformer (19) is mounted to a direct gas pipe (11) and/or gas collector (13) by means of a holder (20) comprising a clamping part (22). In the fixing system in the interior components of the lighter transformer (19) of the subject matter representative embodiment, said clamping part (22) can be realized so as to be coupled to the desired point on the gas collector (13) and/or main gas pipe by means of a novel improved separate holder (20) on the lighter transformer (19). Figure 3 is the lateral view of the holder (20) used in a representative embodiment of the invention. This holder (20) comprises preferably a clamping part (22) and preferably a fixing surface (21). The clamping part (22) and the fixing surface (21) can be produced in different structures providing the subject matter technical solution. In a preferred embodiment of the subject matter invention, said clamping system (22) is in the form of two jaw members (23) positioned preferably mutually. Again in a preferred application of the subject matter invention, said jaw members (23) have a preferably semi-circular form and because of the two jaw members (23) facing one another formed in this form, the gas pipes (11, 13) are grabbed and the holder (20) holds the gas pipes (11, 13). In order to fix the holder (20) to the lighter transformer (19), a fixing surface is formed on the holder (19). This fixing surface is fixed on the lighter transformer (19) and the holder (20) is fixed to any desired place on the gas pipe (11) and/or gas collector pipe (13) as coupled to the lighter transformer (19) because of the clamping part (22). This holder (20) coupled to the subject matter lighter transformer (19) can easily be fixed to the other cooker (10) interior component parts close to the burner because of the pipe like geometry of the interior components of the holder. In Figure 4, preferably a plurality of jaw members (23) which belongs to the clamping part (22) in a representative application of the invention are positioned along a monobloc fixing surface (21) with a lighter transformer (19) in a preferably traverse form. The jaw members (23) positioned in this way increase the holding capability. Figure 5 and 6 illustrate the clamp (24) embodiment forming the clamping part (22) in another alternative application of the invention. This clamp (24) preferably has a form so as to completely encircle the part it clamps preferably to the gas pipes (11, 13). The part where the arms of the clamp (24) combine is fixed by means of preferably at least one pin (25) so that it will not move when it is not dismantled. In the clamped (24) system which is mounted, the movement of the lighter transformer (19) is restricted and preferably two mutual holes are opened on the projection at the end of the clamp (24). The clamp (24) is secured onto the pipes (11, 13) firmly by means of the pin (25) passed through this hole so as to ensure securing. In Figure 7 and Figure 8, in a representative embodiment of the invention, in the application where the holder (20) and the lighter transformer (19) are separate two pieces, during the fixing of the holder (20) to the lighter transformer (19), the preferred applications of these two pieces in a dismantled form are given. In a representative application given in Figure 7, there are at least two latches (26) positioned preferably at least parallel to each other in order to fix the holder (20) to the lighter transformer (19). The holder (20) is fixed to the lighter transformer (19) by being squeezed by means of these latches (26) on the lighter transformer (19). In Figure 8, in another representative application of the invention, the coupling formed for the fixing of the holder (20) and the lighter transformer (19) to each other is in the form of at least one latch (27) and preferably two mutual latch arms (27) formed preferably on the holder (20). There is at least one and preferably two fixing projections (28) squeezed to said latch arm (27) on the lighter transformer. In Figure 9, in a representative embodiment of the invention, the mounted form of the lighter transformer (19) and the holder (20) to each other preferably by means of a latch arm (26) is seen. In another representative application of the invention, the holder (20) and the lighter transformer (19) are all in one piece and one side of the lighter transformer (19) forms itself the fixing surface (21) of the holder (20) and the clamping part comprises the clamping part having preferably the jaw member (23) and/or clamp (24) form formed on this side of the transformer (19). The clamping part (22) can have a flexible or rigid structure and it is preferably made of flexible material. As can be seen in Figure 10, in a representative application of the invention, the clamping part (22) can have forms such as square, triangle, hexagon and oval.
The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
