Abstract
A joint for panels in a kitchen range hood. One panel edge is folded under itself to provide an intermediate flange that is flush with the underside of the first panel edge. The edge of another panel formed as a step including an extension that underlies the intermediate piece. The flange and the extension are secured together, preferably by welding, using a broad flat electrode on the first panel and a point electrode on the extension. The weld is thereby preferentially formed between the flange and the extension so as to avoid visible weld marks on the top of the first panel.

TITLE OF INVENTION
PANEL JOINT FOR KITCHEN RANGE HOOD
FIELD OF THE INVENTION
This invention relates to kitchen range hoods. In particular, this invention relates to the fabrication of joints between the panels of the body of a kitchen range io hood.
BACKGROUND OF THE INVENTION
The body of a kitchen range hood typically comprises a top panel, two side is panels, a rear panel and a bottom panel to accommodate one or more air intakes and fan grills. The panels are generally joined at their edges by welding.
Welds in range hoods may be visible or invisible. An example of a visible weld on a panel joint in a range hood is provided in Fig. 2. The lap joint construction is 2o more clearly illustrated in Fig. 5. The edge of a side panel 12 is made to extend inwardly to provide a horizontal portion to overlay the edge of the top panel 14.
The overlapping edges are then welded together, typically resulting in visible welds 13 as illustrated in Fig. 2. The lap joint also results in an exposed, sharp edge 28 which can result in injury to workmen or users.
One approach that avoids sharp edges is illustrated in Fig. 3. The edge of side panel 12 is provided with a downward extension 16. The edge of top panel 14 is similarly provided with a downward extension 18. Extension 18 is made longer than extension 16. Extension 18 is then folded over and back onto extension 16.
~. i,r,~. 1~.1 The extension assembly is then folded onto itself against the underside of the top surface. This approach provides a flush joint without sharp edges, but is mechanically difficult to achieve.
s Fig. 4 illustrates a prior art form of flange-butt joint (sometimes called an edge flange joint) wherein an edge of side panel 12 is bent inward and includes a downward extension or flange 20. An edge of top panel 14 is bent downward to provide a corresponding extension or flange 22. Extensions 20 and 22 are then welded together, one side of the welding tool being accommodated by the gap 21 io between the main vertical surface of side panel 12 and extension 20. This approach provides a relatively flush seam without sharp edges. However, the gap 21 between the main surface of side panel 12 and extension 20 tends to be small, making it difficult to clean splatter or debris from the weld area. In addition, the cleaning process is made hazardous by the sharp edges of is extensions 20 and 22, particularly when such cleaning is done by hand.
Yet another prior art approach is illustrated in Fig. 6. This is a modified lap joint wherein one of the overlapping edges is doglegged to provide a flusher seam.
The depth of the dogleg is chosen to match the thickness of top panel 14 which ao is then seated in a step formed by the dogleg. The two surfaces are then welded together. This arrangement usually results in a visible weld on the top outer surface 31 of the joint. There also remains an undesirable sharp edge 30.
It is therefore an object of this invention to provide a construction and method of Zs fabricating a joint for the panels of a kitchen range hood that allows the weld to be substantially hidden whole also avoiding the sharp edges on the outer surface of the joint.

PANEL JOINT FOR KITCHEN RANGE HOOD
FIELD OF THE INVENTION
This invention relates to kitchen range hoods. In particular, this invention relates to the fabrication of joints between the panels of the body of a kitchen range io hood.
BACKGROUND OF THE INVENTION
The body of a kitchen range hood typically comprises a top panel, two side is panels, a rear panel and a bottom panel to accommodate one or more air intakes and fan grills. The panels are generally joined at their edges by welding.
Welds in range hoods may be visible or invisible. An example of a visible weld on a panel joint in a range hood is provided in Fig. 2. The lap joint construction is 2o more clearly illustrated in Fig. 5. The edge of a side panel 12 is made to extend inwardly to provide a horizontal portion to overlay the edge of the top panel 14.
The overlapping edges are then welded together, typically resulting in visible welds 13 as illustrated in Fig. 2. The lap joint also results in an exposed, sharp edge 28 which can result in injury to workmen or users.
One approach that avoids sharp edges is illustrated in Fig. 3. The edge of side panel 12 is provided with a downward extension 16. The edge of top panel 14 is similarly provided with a downward extension 18. Extension 18 is made longer than extension 16. Extension 18 is then folded over and back onto extension 16.
~. i,r,~. 1~.1 The extension assembly is then folded onto itself against the underside of the top surface. This approach provides a flush joint without sharp edges, but is mechanically difficult to achieve.
s Fig. 4 illustrates a prior art form of flange-butt joint (sometimes called an edge flange joint) wherein an edge of side panel 12 is bent inward and includes a downward extension or flange 20. An edge of top panel 14 is bent downward to provide a corresponding extension or flange 22. Extensions 20 and 22 are then welded together, one side of the welding tool being accommodated by the gap 21 io between the main vertical surface of side panel 12 and extension 20. This approach provides a relatively flush seam without sharp edges. However, the gap 21 between the main surface of side panel 12 and extension 20 tends to be small, making it difficult to clean splatter or debris from the weld area. In addition, the cleaning process is made hazardous by the sharp edges of is extensions 20 and 22, particularly when such cleaning is done by hand.
Yet another prior art approach is illustrated in Fig. 6. This is a modified lap joint wherein one of the overlapping edges is doglegged to provide a flusher seam.
The depth of the dogleg is chosen to match the thickness of top panel 14 which ao is then seated in a step formed by the dogleg. The two surfaces are then welded together. This arrangement usually results in a visible weld on the top outer surface 31 of the joint. There also remains an undesirable sharp edge 30.

Fig. 2 is a perspective view of a prior art joint between a side panel and a top panel of a range hood;

is DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Fig. 7, the body of a kitchen range hood includes a side panel 12.
Side panel 12 is provided with an inwardly extending portion 15, which may be at a 90 degree angle or, as illustrated in Fig. 7, in a gradual curve terminating in a ao horizontal portion 17.
A downwardly defined step or dogleg includes a downwardly extending portion 30 and a horizontal, inwardly extending portion 32 extending from the end of downward extension 30 at a right angle. The depth of the step, i.e. the extent of Zs downwardly extending portion 30, is about twice the thickness of top panel 14.
Top panel 14 includes a main panel portion having a top surface 17 and an underside 19. The edge of top panel 14 is bent under itself as at 34 to create a flange 36. The bent edge of top panel 14 is then seated in the step created by i a,:
extensions 30 and 32. Flange 36 rests flush with extension 32 in face to face abutment, and the bent edge also abuts extension 30.
The joint may be constructed by first providing the mating flange-butt s arrangement of Fig. 4 but without welding the flanges together. They are then bent (preferably inwardly) to provide the structure of Fig. 7. The joint is then preferably pressed or crimped so as to ensure secure contact across the joint.
This consists of a simpler mechanical manipulation than that required for the fabrication of the prior art joint of Fig. 3. The joint is then ready for welding.
io It will be appreciated that this structure results in the absence of any sharp edges on the top surface of the joint. In the welding process, this arrangement of seam also provides an additional layer (flange 36) of thickness as compared to the prior art lap joint of Fig. 5 or of Fig. 6. This extra layer 36 enhances the ability is to produce a hidden weld on the top surface of the joint, particularly when also using the method of welding the joint according to the invention.
The welding of the joint according to the invention is performed by a form of spot welding. Referring to Fig. 8, a broad, flat electrode 38 is used for the top surface ao 37 of the joint, namely the portion of the main panel surface that overlies flange 36, while a point electrode 40 is used on the bottom (hidden) surface of the joint.
The use of a broad flat electrode on the top surface acts to distribute the current across the surface of the joint. Conversely, the point electrode concentrates the current. As a result, the weld is concentrated near the point electrode, between Zs extension 32 and intermediate layer or flange 36, with minimal welding between the top surface 37 and extension 36.
The result is a relatively invisible weld mark on the outside or top portion of the joint and a solid but hidden weld between extensions 32 and 36. This i.;r; ', construction also allows easy access for the two components of the weld tool while eliminating any sharp edges at the top of the joint and minimizing the obstruction caused by any sharp edges on the inside of the joint.
s While the preferred embodiment of the invention contemplates folding over the edge of the top panel and seating it in a step formed by a side panel edge, the arrangement may be reversed wherein the edge of the side panel is folded over and seated in a step formed by the edge of the top panel.
io The above description has been intended to illustrate the preferred and alternative embodiments of the invention. It will be appreciated that modifications and adaptations to such embodiments may be practiced without departing from the scope of the invention, such scope being most properly defined by reference to this specification as a whole and to the following claims.
