This disclosure relates generally to an elevation apparatus and, more specifically, to an elevation apparatus for raising a connection line, such as a refrigerator water supply line, a gas supply line, or an electrical power cord.
Household refrigerators having an automatic icemaker include a fitting in the back for a water supply line. The water supply line typically is not included with the purchase of the refrigerator, it is incumbent upon the homeowner or installer to purchase and install the water connection line. As a result, local hardware stores offer many different types of supply lines in various price ranges, such as crosslinked polyethylene (PEX), braided stainless steel, or copper. The supply lines are sold in various lengths, typically from 5-8 feet. Often, consumers purchase the least expensive type of supply line, which is ¼″ PEX tubing.
When installed, the water connection line has several feet of slack or extra length to allow the refrigerator to be pulled out away from the wall without having to disconnect the supply line. When the refrigerator is pushed back in, the extra length of supply line, which is typically coiled on the floor, may interfere with the rollers. The supply line may be pinched, kinked, cracked, abraded, or otherwise damaged.
The damage to the supply line may result in a leak, either immediately or at some point in the future. Leakage from the water connection line can be dangerous because the water supply is pressurized, and therefore the leakage will continue until the water supply is shut off. A small leak could go undetected for weeks, and could cause hundreds or even thousands of dollars of damage to the floor, sub-floor, floor joists, and structural beams.
Embodiments of the present invention solve the problem caused by the motion of a piece of equipment interfering with its connection line.
In accordance with one aspect of the disclosure, an elevation apparatus can be used to raise and retain a connection line connected between a piece of moveable equipment and a stationary structure. The connection line has a first end configured to couple with the piece of moveable equipment, and an opposing second end configured to couple with a supply fitting. The elevation apparatus includes a resilient band having a first end and an opposing second end. The first end of the resilient band can be affixed to a mid-span portion of the connection line, and the second end can be stretched and affixed to an object at a height sufficient to impart a first tensioned length to the resilient band, such that the mid-span portion of the band elevates to a first vertical distance. The elevation apparatus further includes a hook configured to be attached to the object and secure the second end of the resilient band.
In one embodiment, the connection line is a refrigerator water supply line connected at the first end to a water supply fitting on the refrigerator, and connected at the second end to a water supply fitting at the stationary structure.
In another embodiment, the connection line is an electrical power cord connected at the first end to the piece of moveable equipment, and configured at the second end to plug into a wall socket.
In other embodiments, the second end of the resilient band can be affixed to the stationary structure, or to the piece of moveable equipment.
In yet another embodiment, lateral movement of the piece of equipment from a first position away from the stationary structure to a second position towards the stationary structure stretches the resilient band to a second tensioned length.
In one embodiment, the resilient band comprises neoprene rubber having a stretch ratio of at least 180%.
In one example, the neoprene rubber has a width in a range between approximately ⅛-inch and ½-inch.
In another example, the neoprene rubber has a textured surface to provide better grip with the connection line.
In accordance with another aspect of the disclosure, an elevation apparatus includes a connection line having a first end configured to connect to a fitting on a piece of moveable equipment, and an opposing second end configured to connect to a stationary supply source. The elevation apparatus further includes a resilient band having a first end and an opposing second end. The first end can be affixed to a mid-span portion of the connection line, and the second end can be stretched and affixed to an object at a height sufficient to impart a first tensioned length to the resilient band, such that the mid-span portion of the band elevates to a first vertical distance.
In accordance with yet another aspect of the disclosure, an elevation apparatus elevates an electrical power cord on a piece of equipment that is moveable from a first position away from a stationary structure, to a second position towards the stationary structure. The elevation apparatus includes a resilient band having a first end and an opposing second end. The first end can be coupled to a mid-span portion of the electrical power cord, and the second end can be coupled to the piece of equipment at a distance sufficient to impart a first tensioned length to the resilient band, such that the mid-span portion of the electrical power cord elevates to a first vertical distance.
In one embodiment, movement of the piece of equipment from the first position to the second position elevates the mid-span portion of the flexible supply line to a second, higher vertical distance.
The features described herein can be better understood with reference to the drawings described below. The drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the invention. In the drawings, like numerals are used to indicate like parts throughout the various views.
Embodiments of the present invention solve the problem caused by a piece of moveable equipment interfering with its connection line. For example,
Typically, the refrigerator 102 is installed in between countertop cabinets, pantries, walls, or the like, resulting in limited access to the back side of the refrigerator. For this reason, refrigerator 102 includes roller elements 108 to permit the refrigerator to be easily moved away from the wall 106. The refrigerator 102 further includes a supply fitting 110 adapted to receive a water connection line 112 that is connected to a household water source. In one example, the supply fitting 110 is a ¼-inch compression fitting.
Experiments conducted by the inventor have demonstrated that the water connection line 112 may be any type of line commercially-available for the intended purpose. The connection line 112 may be flexible or rigid. Examples of flexible line include, but are not limited to, polyethylene, cross-linked polyethylene (PEX), or braided hose comprising a braided stainless steel outer sheathing with inner nylon-reinforced vinyl tubing. Examples of rigid line include, but are not limited to, ¼-inch copper tubing. The length of the water connection line 112 will vary depending upon the specific installation, as explained below, but in general a longer hose is useful, for example in the range of 8-10 feet. A first end 114 of the water connection line 112 connects to the supply fitting 110 on the refrigerator, and an opposing second end 116 connects to a water supply fitting 118 on the wall 106. In the illustrated example, the water supply fitting 118 is a quarter-turn shutoff valve. The valve 118 may be connected to copper tubing 120 that taps off a cold-water supply line elsewhere in the home (not shown).
The disclosed elevation apparatus 100 includes a resilient band 122 configured to keep the water connection line 112 elevated off the floor 104 and prevent the line from interfering with the movement of the refrigerator 102. In one example, the resilient band 122 may be formed from a highly-engineered elastomer material, such as neoprene. A first end 124 of the resilient band 122 is secured to a mid-span portion 126 of the water connection line 112 and an opposing second end 128 of the resilient band 122 is secured to an upper portion of the refrigerator 102, at a height above first end 124.
In one example, shown in
The inventor of the present invention experimented with numerous resilient band 122 configurations, such as ⅛- or ¼-inch diameter bungee cord. However, bungee cord tended to slip along the connection line 112, which could potentially prevent the connection line 112 from lifting properly. Furthermore, when the connection line 112 was metal braided hose, the slippage caused the bungee cord to abrade, which could eventually result in a failure of the resilient band. A preferred material selection for the resilient band 122 is neoprene rubber, having a width W in a range between approximately ⅛-inch and ½-inch, a thickness of approximately 1/16-inch, a length of approximately 3 feet, and a stretch ratio of at least 180%. The resilient band 122 may further include a textured surface 133 to provide a better grip with the connection line 112. In one example, the neoprene rubber may include a block or diamond surface texture 133.

One of the improvements of the disclosed elevation apparatus is that it prevents costly water damage when moving a refrigerator. The refrigerator can be pushed into place against the wall without having to check and make sure the roller elements are not interfering with the water supply line. This is particularly helpful because the pushing operation is a ‘blind’ operation; the person pushing the refrigerator cannot see the floor behind it.
Some advantages of the disclosed elevation apparatus are that it is a low cost solution that can be easily installed without the need to hire a professional plumber.
