Abstract:
A high-loop bracket has a handle portion that allows a user to manipulate a hose support portion that supports an electric dishwasher&#39;s discharge hose into a position that easily forms a high rise loop. The high rise loop is fixed against a sink base cabinet by securing an easy to reach mount portion of the high-loop bracket. Preferably, the high-loop bracket is formed from a single sheet of stainless steel that is bent to create the various portions of the bracket.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    To prevent sink water from flowing into a dishwasher, a portion of a dishwasher&#39;s discharge hose needs to be higher than the highest level of water in a sink basin that shares a drain with the dishwasher. Some discharge hoses are connected to anti-siphon devices that mount above countertop level, but these devices make a mess when they fail. Commonly, dishwasher discharge hoses are provided with a high rise loop by attaching a bracket near the top of a kitchen&#39;s sink base cabinet before a sink is installed. It is often nearly impossible to remove such a bracket without removing the sink, so changing the hose or trying to loosen the hose to be able to pull out a dishwasher becomes challenging. There is a need for an easy method to position and remove a high rise loop for a dishwasher&#39;s discharge hose. 
       SUMMARY OF THE INVENTION 
       [0002]    The preferred embodiment of the present invention uses a stainless steel bracket characterized by a handle portion having a hose support portion on one end and a cabinet mount portion on the other end. When this high-loop bracket is installed, a high rise loop is formed in a discharge hose supported by the hose support portion, preferably as high as possible between a sink basin and a wall of a sink base cabinet. The discharge hose is passed through the hose support portion, and then the handle portion is used to manipulate the discharge hose to create and position a high rise loop in a desired position. Once positioned, the mount portion is secured to the sink base cabinet using one or more fasteners, preferably screws. Unlike common hose brackets, the relatively long handle portion causes the mounting means to be adequately spaced below the high rise loop such that the mounting means is visible and easily accessible below the sink basin. With easy access to the mount portion, a common screwdriver is employed to screw the mount portion to the sink base cabinet. Alternative hose support portions and mounting means will be discussed, but all high-loop brackets will include a handle portion that makes it easy to create and position a high rise loop.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0034]    This detailed description will describe a high-loop bracket  10  from the top down, followed by its installation. Generally, as shown in the various figures, the high-loop bracket has a hose support portion  14  above a handle portion  22  and a mount portion  24 . In the most preferred embodiment, such as is shown in  FIGS. 1-5 , the high-loop bracket is made from a single piece of stainless steel that is cut, folded and bent to shape so that it is strong and reliable for at least the life of a dishwasher. Other rigid materials, such as plastic or aluminum, could be used to mold or form a high-loop bracket. When metal is used, folded edges  26  in the handle portion should reduce the risk of sharp edges cutting people or surroundings while adding strength to the high-loop bracket. Alternate embodiments of the present invention will follow the description of the preferred embodiment and its installation. Where reference numbers in one figure are the same as another figure, those reference numbers carry substantially the same meaning. Preferred sizes, materials and methods of attachment will be discussed, but these preferences are not intended to exclude other suitable or functionally equivalent sizes, materials or methods of attachment. 
         [0035]    As shown in  FIGS. 1-3 , the top of the preferred high-loop bracket  10  has a hose support portion  14  characterized by a hose aperture  12 . An outer diameter of the hose support portion will be determined by the type and thickness of the material used to make the high-loop bracket. The preferred hose support portion is made from approximately 1 mm thick stainless steel (such as 22 gauge) that is die cut to have about a 60 mm outer diameter. An inner diameter of the hose support portion, which effectively defines the hose aperture, is large enough, such as about 40 mm, for an electric dishwashing machine&#39;s waste water discharge hose  30  to pass through the hose aperture far enough so that approximately a mid-section of the hose can be supported. When a high-loop bracket is constructed from metal, a guard  16  is preferably installed around an inner diameter of the hose support portion such that there are no sharp edges around the hose aperture that could wear or cut a discharge hose. One such guard is a length of u-shaped plastic or rubber that is pressed around an inside edge of the hose support portion, with the ends of the guard meeting at a split  18 . Alternatively, the guard could be tape, foam or other non-abrasive material. 
         [0036]    As shown in  FIGS. 1-3 , the hose support portion  14  is connected to the handle portion  22  of the high-loop bracket  10  by a bend  20 . Preferably, the entire high-loop bracket is made from a single sheet of stainless steel, so the bend is made for the purpose of providing a flat mounting surface that causes a discharge hose to run along a cabinet wall. The preferred bend will make about a 90 degree turn so that a plane defined by the handle portion is substantially perpendicular to a plane defined by the hose aperture. When twisting the sheet metal to form the bend, it is preferred that a tangent of an outer diameter of the hose support portion lies approximately in the plane defined by the handle portion so that a discharge hose can be positioned close to a wall of a base cabinet without interfering with the ability to mount the high-loop bracket. 
         [0037]    The handle portion  22  of the high-loop bracket  10  shown in  FIGS. 1-3  is at least partially continuous with the bend  20 . To allow for enough material to make the folded edge  26 , the initial width of the sheet metal that is part of the handle portion is much wider than the sheet metal at the bend. The preferred width of sheet metal is about 20 mm, with the each folded edge on either side of the width consuming about 3 mm of the sheet metal. The folded edges should be flattened against the handle portion to reduce exposure of any sharp edges. If desired, a plastic coating or cover can be placed over the handle portion. The overall length of the handle portion in  FIGS. 1-3  is about 13 cm, but it could be much longer to accommodate deeper sink basins, such as 30 cm or longer. The free end of the handle portion can be finished so that it is smooth and rounded. 
         [0038]    Near an end of the handle portion  22 , opposite the hose support portion  14 , is a mount portion  24 . The mount portion shown in the preferred embodiment is preferably characterized by holes in the handle portion that are sized for common wood screws. The holes shown have about a 4 mm diameter. One or more of the holes can be selected for use at the time the high-loop bracket is installed. A separate holder could be secured to a base cabinet to accept the mount portion, such as by snapping or sliding into place, which might be preferred if the high-loop bracket is constructed of plastic. 
         [0039]    To install the preferred high-loop bracket  10 , a discharge hose  30  is passed through the hose support portion  14 , as shown in  FIG. 4 . If desired, a hot water supply hose for a dishwasher can be passed through the hose support portion at this time. An installer then grasps the handle portion  22  of the high-loop bracket with their hand  50  and manipulates the high-loop bracket until a desired high rise loop  32  is formed in the discharge hose in a desired position. The high-loop bracket is preferably pushed upward until the hose support portion is near or abuts a countertop  42 . Grasping just the handle portion  22  of the high-loop bracket will allow an installer to blindly manipulate the discharge hose between a sink base cabinet  40  and a sink basin  44  until a high rise loop  32  is formed in the discharge hose. As shown in  FIG. 5 , the mount portion is secured against a wall of the sink base cabinet. A piece of double sided foam tape (not shown) can be used to temporarily position the handle portion against the cabinet. A screw is used to secure the mount portion to the cabinet; and additional screws can be used as deemed necessary. The discharge hose is connected to a garbage disposal  46  in the normal way. 
         [0040]      FIGS. 6-8  show an alternate embodiment of the high-loop bracket  10  of the present invention. Rather than bending the handle portion  22  by about ninety degrees where it meets the hose support portion  14 , the sheet metal is simply curled back on itself to form the hose support portion. Rivets or spot welds  48  can be used to fix the curled end of the hose support portion. The curled end  28  effectively meets the handle portion without any twisting so that forming the high-loop bracket is a relatively simple process. The installation of the high-loop bracket shown in  FIGS. 6-8  is the same as for the preferred embodiment. If desired, the folded edges  26  can be extended into the hose support portion so that they are continuous all the way to the curled end. 
         [0041]      FIGS. 9 and 10  show another alternate embodiment of the high-loop bracket  10  of the present invention. Sheet metal is stamped to form the piece shown in  FIG. 9 , including a slot  52  and hook  54 . The sheet metal is folded and then rolled until the curled end is close enough to the slot such that the hook can be pushed into the slot to form the hose support portion  14 . The hook may be bent to keep it from slipping out of the slot. The hook could be unhooked, if desired, to allow the discharge hose to be inserted into the hose support portion, and then the hook may be reinserted into the slot. 
         [0042]    The various embodiments of the present invention can be molded or formed from plastic rather than from sheet metal. One skilled in the art will adjust the thickness of the plastic to achieve a desired strength. Similarly, any folded edges and bends desired in a metal construction can be eliminated to allow for known equivalent structures and processes when making a part out of plastic. As already mentioned, it may be beneficial to make a plastic high-loop bracket as multiple piece parts that are assembled during installation, such as by snapping or sliding parts of the high-loop bracket together. 
         [0043]    While a preferred form of the invention has been shown and described, it will be realized that alterations and modifications may be made thereto without departing from the scope of the following claims.
