The present disclosure relates to an assembly having a handle integrated into a front panel of door or drawer.
2. Field of the Related Art
Typical foodservice door or drawer assemblies require additional components to achieve a “handle” for opening, closing, or generally changing the position of the door or drawer. These handles can vary from simple plastic or other non-steel components snapped into a door or drawer front panel or others purchased or formed and secured to the door or drawer front panel by mechanical fasteners or welding.
Typical handles in the food service industry have recesses, corners, coves, or similar crevasses to clean. Silicone may be required to close these areas and over time re-applying silicone is required. Commonly, this is neglected or forgotten about and does not happen, so food particles become lodged in the areas. Over time, these food particles begin to decompose and create sanitary risks.
Typical handle designs are vulnerable to a high probability of breakage. For example, carts that are pushed through a restaurant kitchen can collide with protruding handles or crush flush plastic handles.
Additionally, some handle designs provide a less than adequate gripping capability. Handle position, i.e., height above the floor, as well as depth of gripping area are both causes for this. Doors with handles of less gripping capability may require an “eagle claw” gripping method to open a door. Exposed door gaskets in this gripping area are frequently damaged, or at minimum soiled and require additional cleaning.
Accordingly, there is a need for a handle which overcomes the deficiencies of conventional handle designs.
The present disclosure provides an assembly having a handle integrated into a front panel or door which eliminates the need for additional parts and purchased components. Because the front panel and handle are one integrated piece, there is nothing to be exposed to the dangers of a busy kitchen, such as injury to a person or damage to the handle.
The present disclosure provides an assembly having a handle integrated into a front panel which makes cleaning easier and eliminates the possibility of food particles and other debris from becoming lodged in seams and crevices. Cleaning the front panel and handle becomes much easier from a user maintenance standpoint, especially when used in busy environments with high levels of activity.
The present disclosure provides an assembly having a flat continuous front surface which can be easily wiped clean and a “U” shaped continuous trough which is open at both ends and easily wipeable. Both areas can utilize the same type of restaurant equipment cleaner.
The present disclosure provides an assembly having a handle integrated into a front panel with a recessed gripping area suitable for any person, no matter the person's size because a comfortable grip location can be found anywhere along the entire length of the integrated door/drawer handle.
Wet foam insulation leakage, which is a manufacturing complication, is lessened by the assembly of the present disclosure. Eliminating seams in the front assembly eliminate possible areas for foam to escape during the insulation process. Leaked wet foam adheres and hardens to the front exterior and requires additional time for removal.
The present disclosure also provides for a rear closed hem of the handle that affords gasket protection. The gasket is further protected from hands as well as protection from foreign matter spilled or spattered on the front of the hem. As used herein, a hem is the result of folding metal back on itself. Hemming is a bending operation that bends and folds an edge of sheet metal back upon itself. Hemming conceals the sharp edge of sheet metal.
The present disclosure provides for an integrated door/drawer and handle that is symmetrical about either a horizontal or vertical axis. Thus, the door/drawer is capable of being mounted to a fixture such that it can be opened left, right, up, or down.
An assembly having a handle integrated into a front panel of door or drawer is constructed from a single piece of sheet metal and has a front panel, a handle, a trough, and a gasket barrier. The handle is formed by a tear drop hem. The gasket barrier is formed by a closed hem. The trough is formed by the area between the handle and the gasket barrier.
Referring to the drawings and, in particular,
Assembly 10 is formed from a single sheet of metal. Assembly 10 has a front panel 12, a handle 14, a trough 16, and a gasket barrier 18. Front panel 12 is flat.
Handle 14 has a front surface 20, a rear surface 22, and is formed by a tear drop hem 24, creating opening 26. Surface 20 is coplanar and thus flush with front panel 12. Surface 22 contacts the rear of front panel 12 at a bend 30.
Trough 16 is generally “U” shaped and formed between handle 14 and gasket barrier 18, by bends 30 and 40. Trough 16 is has a surface 34 extending from bend 30 and away from front panel 12.
Gasket barrier 18 has a front side 42 formed at bend 40 and rear side 46. Gasket barrier 18 extends from a bend 40 and is formed by a closed hem 44. Front side 42 and rear side 46 are generally parallel.
In a closed position, i.e. the door or drawer assembly being shut, gasket barrier 18 forms a seal with gasket 60.
Surface 34 is generally perpendicular to front panel 12.
Gasket barrier 18 can be parallel to front panel 12.
Handle 14 can have a texture (not shown), preferably on surface 22. Advantageously, a textured surface increases gripability and reduces slippage of a user's hand(s) when the handle is wet or moist.
The texture can be formed of a series of ridges that are preferably parallel to the length of tear drop hem 24. Alternatively, the texture can be ridges perpendicular to the length of tear drop hem 24 or cross hatched ridges. The texture can also be a sandpaper-like texture.
Texturizing, or applying the texture can be achieved by grinding, etching, laser, and the like.
The texture can be etched onto the surface of the metal. Alternatively, handle 14 can have a textured strip adhered to the interior of the handle. Such a strip can be, for example plastic, or metal. The strip is preferably waterproof and/or resistant to movement or dislocation once applied to the interior of the handle. The material for the textured strip is optionally anti-microbial to reduce the transmission of bacteria among users and prevent bacteria and fungus from growing on the surface and/or spreading to other surfaces.
Handle 14 is between 0.25 and 2 inches wide, or at least large enough for a user to grip the handle. Front side 42 of gasket barrier 18 is dimensioned between 0.75 and 3 inches, preferable between 1 and 1.3 inches, and most preferably about 1.15 inches. Surface 20 and rear side 46 are spaced apart by between 1 and 3 inches, preferably between 1.5 and 2 inches, and most preferably about 1.75 inches.
In a preferred embodiment, handle 14 is uniform in cross-section and extends substantially the length of the door/drawer.
A method for forming Assembly 10 is as follows. A single sheet of metal is selected. A first bending forms tear drop hem 24 with surface 20 coplanar to front panel 12 and a surface 22, yielding front panel 12 and handle 14. A second bending at bend 30 creates surface 34. An outside surface of bend 30 can contact an inside surface of front panel 12. A third bending at bend 40 creates surface 42, yielding trough 16. A fourth bending forms closed hem 44, yielding gasket barrier 18 and surface 46.
Referring to
Assembly 10 can be made of steel, stainless steel, aluminum, copper, zinc, or the like. Assembly 10 should be made of a material that is easy to keep clean and sanitary.
Advantageously, using stainless steel is generally low maintenance and will prevent assembly 10 from readily corroding, rusting, or staining from water over time. Stainless steel is generally highly resistant to acids and bases. Further, stainless steel is a relatively poor conductor of electricity.
Stainless steel can be easily cleaned with a soft cloth and water, mild detergent, and even glass cleaner.
The steel gauge of assembly 10 can be 8-28 gauge, while most preferably 22 gauge.
As shown in
Referring now to
The integrated door/drawer and handle of the present disclosure can be adapted to fit a typical cabinet construction and can be used in a side by side double door arrangement. For example, in a closed position, the gasket barrier of each door forms a boundary or is substantially adjacent with the other. The handles meet each other in the center of the cabinet. Thus the doors can swing and create a single opening.
Referring now to
Preferably, border 90 has at least a first and second fixed member 91 and 92, each with a first and second front face 95 and 96.
Front panel 12 can fit flush between first and second fixed members 95 and 96, while a countertop surface 98 extends over the opening in a frontward direction. Thus, the front of the cabinet, i.e., the first front face, second front face, and front panel, is in a single plane with a gap 99 between the handle and the second front face, allowing a user to grip the handle. The gasket barrier 18 rests flush with the second fixed member.
The techniques described herein are exemplary, and should not be construed as implying any particular limitation on the present disclosure. It should be understood that various alternatives, combinations, and modifications could be devised by those skilled in the art from the present disclosure. For example, steps associated with the processes or methods described herein can be performed in any order, unless otherwise specified or dictated by the steps themselves. The present disclosure is intended to embrace all such alternatives, modifications, and variances that fall within the scope of the appended claims.
