Description

Field of the Invention

[0001] The current invention refers to a gas burner assembly, usually used in firing equipment based on gas burn, integrated by at least two bodies which, cooperate with each other, define a locking mechanism. Specifically, the current invention reveals an integrated gas burner assembly, preferably, simply by a base and a lid, in which said lid comprises an odd construction capable of compose a locking mechanism related to the base.

Background of the Invention

[0002] As is it broadly known, conventional firing equipment are basically built by firing tables in which are disposed burner assemblies by which flame is outputted that effectively promotes the desired firing process, in that said burners normally comprises a main body of base and a lid that, in a general way, helps on forming gantries for passage of an air-fuel mixture, whose intensity can be defined by the own equipment operator actuating the control handles of register, between a range determined by the burner project.

[0003] However said burner lids normally comprises pieces in form of plates or lids that are simply supported on the body of the burners without, however, foresee any type of fixing means to keep them permanently on the correct position during the utilization of the firing apparatus. Thus, despite the current marked be provided with several configurations of lids that can have their own support conditions plus male-female engaging, coupling with internal accommodation or similar forms, the same always keep free on the main body of the burners.

[0004] Therefore, a problem refers to transport logistics of the gas burners assemblies. This because during transport, normally by the highways, there is a need to keep the gas burner assemblies assembled so the pieces will not be damaged or misplaced. To avoid such problem, the current prior art comprises some specific techniques, which foresee, normally, using extra components, as for example, adhesive tapes, disposable templates, among others.

[0005] Another problem known by the specialists on the art refers to the assembling of the gas burner assemblies. This is because is indispensable that the lid and base, among other eventual components, should be mounted in perfectly harmony, at the risk of malfunctioning and failure to maintain the flame, after all, the incorrect assembling of this elements can unbalance the exit speed of the mixture by gantries, promoting known problems as "flame detachment" (the flame "detaches" from the burner, being, in extreme cases, extinct, generating thus gas not burned leakage), or "gathering flame" (the flame burns inside the burner body causing superheating of the piece and consequently damage due to piece softening or melting, making it useless permanently in the worst cases).

[0006] One solution that was developed trying to minimize such problem is found on document KR2004059675, that foresee using an over lid for the burner lid, which fix to itself with the aid of a connector that cooperates with the structure that can be the own tripod of the firing equipment. Thus, there are used several devices to avoid lid displacement related to the main body of the burner without, however, foresee any fixing means, effective and directly, the lid to the burner body revealing, however, a complex and costly solution.

[0007] Document JP200308512, in turn, describes a solution in which the burner body provides support elements similar to hooks intended to be coupled to the cover thereby to immobilize and simultaneously prevent access of liquids to the internal region of the firing apparatus. Despite having a primary purpose of sealing, this solution also prevents free travel of the lid, but also with a complex solution that relies on many small components for its execution, besides demanding a constructive complex process and assembly conditions and disassembly also extremely complex - including the cleaning procedures and maintenance of firing equipment.

[0008] Note, therefore, that the present state of the art lacks solutions to keep the burners lid of firing equipment fixedly coupled to its support structure so as to avoid unwanted movements and, moreover, allow safe use of firing equipment in locations subject to rocking and / or vibration, for example, trailers and watercraft. Therefore, it is necessary to develop solutions to secure the lids to the bodies of firing equipment burners in a direct, practical and effective, moreover, not demands the handling of various components for their assembly and can be mounted and disassembled simply to facilitate cleaning procedures that are often needed in this type of appliance.

[0009] Based on this scenario the invention in question arises.

Objects of the Invention

[0010] It is therefore one objective of the subject invention that the gas burner assembly is provided with a locking mechanism capable of ensure that the base and lid remain assembled without the need for additional components for any kind of transportation.

[0011] Another among the objectives of the invention is to disclose a lid for firing equipment burner that includes, in its very structure, the means to promote attachment to the burner body and simultaneously originate the gantries for output flames.

[0012] It is also an object of the invention to provide a burner assembly which enables safe use of firing equipment in places subject to vibration and / or motion as, for example, in trucks, and watercraft.

[0013] In summary, it is an object of the present invention to provide a burner assembly for a firing equipment providing greater security for the use and handling of firing equipment, especially for facilitating the assembly process and disassembly requires the lid on the body of the burner for cleaning and prevent unwanted displacement of the covers burners while using the equipment or during transport.

Detailed Description of the Invention

[0022] The present invention relates to a burner assembly for firing equipment, generally comprises at least two bodies capable of detachably cooperative association with each other, and laid still a locking means defined by the cooperative interaction between said two bodies.

[0023] Due to this constructive concept, all of the goals of the subject invention are achieved, comprising a preferred embodiment illustrated in Figures 1 to 6.

[0024] According to these figures, it is noted that the gas burner assembly is essentially formed by two bodies, which are indicated by reference numerals 1 and 2.

[0025] According to the preferred embodiment illustrated in figures 1 to 6, the body 1 comprises a burner assembly base and the body 2 comprises the lid of the burner assembly. Of course, this condition is not exhaustive and may even be reversed.

[0026] The body 1 comprises a surrounding wall 11 closed at one end by a plate 12, which comprises conventional means (not shown) for fastening on a firing table and a an opening intake 15 of fuel gas and air and fuel mixture coming from any source. The surrounding wall 11 of said body 1 further comprises at least one rib 13 and / or at least one groove 14, preferably surrounding both.

[0027] The body 2 comprises a plate 21 which perpendicularly project multiple adjacent walls 22, which are spaced from each other by slits 26 (vertical spaces). At the most, each of said adjacent end walls 22 has an end 23 directed toward the center of the plate 21.

[0028] Moreover, said body 2 further comprises two regions capable of deformation by the application of external force, one of these regions (indicated by reference 24) comprises a central plate 21, and the other of these regions (indicated by reference 25) comprises its own adjacent walls 22 spaced apart.

[0029] Due to the existence of two regions 24 and 25 capable of deforming by the application of external force, the body 2 is able to assume two stable positions, which are best shown in Figures 7.1 and 7.2.

[0030] In Figure 7.1, the body 2 is in a position of "disengagement", which is achieved through the application of an external force F1 in the region 24 subject to deformation (central plate 21) from the body 2 . In Figure 7.2, the body 2 is in a "locking" position, which is achieved through the application of an external force F2 in the region 25 subject to deformation (own adjacent walls 22) of the body 2.

[0031] In summary, the major difference between the position of "disengaging" and "engaging" refers to the virtual diameter defined by end edges 23 of adjacent walls 22. In the position "disengaging" the diameter is slightly larger than the diameter of the plate 21, while the position of "engaging" the diameter is slightly larger than the diameter of the plate 21. This allows the body 2, by assuming two stable positions among them and cooperating when the body 1, performs as a latch means, after all, one of the stable positions culminates in the groove between said bodies 1 and 2, while the other stable position culminates in the disengagement between said bodies 1 and 2.

[0032] Thus, the mere application of an external force (F1 or F2) in the body 2 proper region (regions 24 and 25 capable of deformation) provides the engagement or disengagement between the bodies 1 and 2 which define the burner assembly gas now revealed.

[0033] Occasionally, it is noted that the application of an external force F1 in the region 24 capable of body 2 deforming results in the disengagement position between said bodies 1 and 2 and the application of an external force F2 in the region 25 capable of deformation body 2 results in locking position between said bodies 1 and 2.

[0034] The aforementioned end points 23 of adjacent walls 22 are specifically dedicated to the cooperative action with the rib 13 and / or groove 14 of the surrounding wall 11, so that the engaging position between said bodies 1 and 2, the ends 23 of the adjacent end walls 22 are housed in the groove 14 of the surrounding wall 11, preventing relative movement of existing (axial and / or longitudinal) between said bodies 1 and 2.

[0035] Of course, the gas burner assembly disclosed herein comprises three gantries.

[0036] According to the embodiment illustrated in figures 1 to 6, the said gantries 3 are arranged in the body 2 and, more specifically, two slits 26 of the body.

[0037] Alternatively (not shown), the said gantries 3 may be arranged in other areas of the body 2, the body 1 (preferably, the surrounding wall 11), or between the body 1 and the body 2.

[0038] Finally, it is worth noting that although it was only cited one preferred embodiment, the scope of the invention in question is broader, being limited solely by the claims and possible equivalent means.
