The connector may be connected by wire or wirelessly to a controller of a device to which the shelf is mounted such as a refrigerator 100 (shown referring to FIG. 1). One or more connectors may be associated with each shelf. For example, a first connector may provide a ground potential, a second connector may provide an alternating current/voltage or a direct current/voltage, and a third connector may provide a digital or analog data signal though a fewer or a greater number of connectors may be associated with each shelf. Power provided to the connector may be modulated, for example, using pulse width modulation to vary the amount of power, for example, to dim a light. Various voltage levels may be provided such as 12 volts (V), 24 V, etc.

Referring to FIG. 1, an illustrative device is shown in which a plurality of shelves 102 is mounted. FIG. 1 shows a front view of refrigerator 100 with open doors to show a portion of two interior spaces that include the plurality of shelves 102. The plurality of shelves 102 are mounted to a plurality of ladders 104 not all of which are visible. The plurality of ladders 104 may be mounted to one or more walls that define each interior space including a door 106 that may enclose the interior space. One or more ladders of the plurality of ladders 104 may be used to mount each shelf of the plurality of shelves 102. For example, a first left ladder (not shown) and a first right ladder 108 may be mounted to a first back wall 110 to extend vertically near a left edge and near a right edge of first back wall 110, respectively. A second left ladder 112 and a second right ladder (not shown) may be mounted to a second back wall 114 to extend vertically near a left edge and near a right edge of second back wall 114, respectively. A ladder may be mounted in other locations and to other walls that define the interior space. For example, in an alternative embodiment, the ladder may extend horizontally or in another direction. As another example, the ladder may be mounted at a center of the back wall or to a side wall. As yet another example, the ladder(s) may be mounted to door 106. A drawer or other storage space may further be mounted to the shelf. The shelf may be included in a heated or a cooled space or in a space at an ambient temperature. The cooled space, for example, may be a refrigerated space or a freezer space. One or more of the plurality of shelves 102 may extend a portion of a width and/or a depth of the interior space or an entire width and/or an entire depth of the interior space. One or more of the plurality of shelves 102 further may extend a portion of a width of door 106 or an entire width of door 106.

Referring to FIG. 2, a back right side view of a shelf 200 of the plurality of shelves 102 is shown in accordance with an illustrative embodiment. Shelf 200 includes a plate 202, a right brace 204 and a left brace 206. A greater or a fewer number of braces may be used in alternative embodiments. For example, an additional brace may be included to support a larger plate 202. As another example, a single center brace may be used with a different support system such as a molded platform on either side of plate 202. Items can be placed on plate 202. The objects (not shown) connected to receive the electrical signal may be mounted anywhere on or adjacent to shelf 200 including below shelf 200 and/or to a front of shelf 200. The components of shelf 200 may be formed of one or more materials, such as metal, glass, and/or plastic having a sufficient strength and rigidity to provide the illustrated and/or described function. For example, plate 202, a drawer, or other receptacle may be formed of one or more materials, such as metal, glass, and/or plastic having a sufficient strength and rigidity to support food items or other items stored in refrigerator 100.

Plate 202 is mounted to right brace 204 and left brace 206. Plate 202 may form a variety of shapes including a polygon, a circle, etc. of various sizes. In an illustrative embodiment, plate 202 is attached to right brace 204 and to left brace 206, for example, using an adhesive though in alternative embodiments other mounting mechanisms may be used or plate 202 may not be attached to right brace 204 and left brace 206. A drawer or other receptacle may be mounted to extend upward or downward from plate 202.

Right brace 204 may include a right support arm 208 and a right bracket 210. Left brace 206 may include a left support arm 212 and a left bracket 214. Left brace 206 may form a mirror image of right brace 204 relative to a vertical plane through a center of a space between right brace 204 and left brace 206. Right support arm 208 may have various shapes and dimensions. For example, a height of right support arm 208 may narrow towards a front of shelf 200 so that less material is used and so that right support arm 208 is less visible to a consumer though the height, a width, and the material are selected to be strong enough to support a weight of items placed on plate 202. Using various openings formed in first right ladder 108 and in the first left ladder, a position of shelf 200 can be adjusted within the interior space or on door 106 or shelf 200 can be removed from the interior space or from door 106.

In the illustrative embodiment, right brace 204 may include a right curved transition wall 218 formed between right support arm 208 and right bracket 210 to assist in alignment of right bracket 210 with the ladder to which shelf 200 is mounted on a right side.

First shelf connector 500 and second shelf connector 502 further may include a greater or a fewer fastener aperture walls.

A wire 900 may extend from connection housing 700 below wire cover 702. In the illustrative embodiment, wire 900 extends to a front edge of plate 202 of shelf 200 though wire 900 can extend to any location on, in, or adjacent to shelf 200. Wire 900 may be an insulated wire made of various conductive materials and gauge sizes based on the object(s) connected to receive the electric signal.

Referring to FIG. 10, a left side transparent view of first shelf connector 500 is shown in accordance with an illustrative embodiment. Wire 900 is electrically connected at a first end 1000 to a second internal wire 1002. Second internal wire 1002 is mounted within first shelf connector 500 and is electrically connected at a first end 1004 to first end 1000 of wire 900 and at a second end 1006 to contact pad 712. Second internal wire 1002 may be an insulated wire made of various conductive materials and gauge sizes. In an alternative embodiment, a solid conductor component may replace second internal wire 1002 to electrically connect first end 1000 of wire 900 to contact pad 712. First end 1000 of wire 900 further may contact second internal wire 1002 at other locations within or adjacent to first shelf connector 500. For example the solid conductor component may electrically contact wire 900 external to first shelf connector 500. Contact pad 712 is mounted horizontally to a lower edge of a hook formed by connection housing 700 and provides an electrical contact point for the electrical signal provided to/from shelf 200.

When first shelf connector 500 is mounted to right bracket 210, a first fastener 708 is inserted into third fastener aperture wall 704 and into first fastener aperture wall 310, which are aligned. Similarly, a second fastener 710 is inserted into fourth fastener aperture wall 706 and into second fastener aperture wall 312, which are aligned. Other mounting mechanisms as well as various fasteners, such as screws or rivets, may be used to mount first shelf connector 500 to right bracket 210. Head portion 300 of right bracket 210 covers a left side of connection housing 700 of first shelf connector 500. In the illustrative embodiment, wire 900 is curved adjacent curved transition wall 218 and extends beneath support wall 216 so that wire 900 is not readily visible and not easily snagged on items stored on or around shelf 200.

The components of first shelf connector 500 may be formed of one or more materials, such as metal, glass, and/or plastic having a sufficient strength and rigidity to provide the illustrated and/or described function. For example, connection housing 700 and wire cover 702 may be formed of a single continuous piece of insulating material using a molding process. Contact pad 712 may be formed of an electrically conductive material that is sized and shaped based on an electrical contact to which contact pad 712 is joined when shelf 200 is mounted to the ladder.

A second wire 1204 may extend from second connection housing 1100 below second wire cover 1102. In the illustrative embodiment, second wire 1204 extends to the front edge of plate 202 of shelf 200 though second wire 1204 can extend to any location on, in, or adjacent to shelf 200. Similar to wire 900, second wire 1204 is electrically connected at a first end (not shown) to second contact pad 1104 that is mounted horizontally to a lower edge of a hook formed by second connection housing 1100. Second contact pad 1104 provides a second electrical contact point for a second electrical signal provided to/from shelf 200. In an illustrative embodiment, second wire 1204 and wire 900 provide power to a device to which second wire 1204 and wire 900 are connected at second ends opposite the first ends. For example, one of wire 900 and second wire 1204 may provide a ground potential while the other provides a positive voltage/current. In alternative embodiments, either or both of wire 900 and second wire 1204 may provide a data signal.

When second shelf connector 502 is mounted to right bracket 210, first fastener 708 is inserted into third fastener aperture wall 704 (when first shelf connector 500 is also mounted to right bracket 210), into first fastener aperture wall 310, and into fifth fastener aperture wall 1200, which are aligned. Similarly, second fastener 710 is inserted into fourth fastener aperture wall 706, into second fastener aperture wall 312, and into sixth fastener aperture wall 1202, which are aligned. In the illustrative embodiment, second wire 1204 is curved adjacent curved transition wall 218 and extends beneath support wall 216 so that second wire 1204 is not readily visible and not easily snagged on items stored on or around shelf 200. In the illustrative embodiment, hook head contact surface 306 of right bracket 210 is positioned between contact pad 712 of first shelf connector 500 and second contact pad 1104 of second shelf connector 502 when both first shelf connector 500 and second shelf connector 502 are mounted to right bracket 210.

In the illustrative embodiment, sliding wall 1520 may form a U-shape that extends around connector body 1506 on three sides and may include a right arm 1544, a front arm 1546, and a left arm 1548. In the illustrative embodiment, sliding wall 1520 includes right blocking aperture walls 1522, left blocking aperture walls 1524, right aperture walls 1526, and left aperture walls 1528. The right blocking aperture walls 1522 and the right aperture walls 1526 are formed through right arm 1544, and the left blocking aperture walls 1524 and the left aperture walls 1528 are formed through left arm 1548. In an alternative embodiment, sliding wall 1520 may not have a U-shape and may be comprised of two walls that separately slide along the right and the left sides of connector body 1506. In the illustrative embodiment, each of the right blocking aperture walls 1522, left blocking aperture walls 1524, right aperture walls 1526, and left aperture walls 1528 include a pair of walls to correspond with the number of right mounting pins 1502 and left mounting pins 1504 that correspond with a number of right ladder connector aperture walls 1308 and left ladder connector aperture walls 1310 at each vertical location.

Connector base 1507 may include a front base wall 1542, a right base wall 1543, and a left base wall 1800 that form a U-shape. A right plurality of tabs 1530 extend up from right base wall 1543 of connector base 1507. A left plurality of tabs 1532 extend up from left base wall 1800 of connector base 1507. A right tab 1538 extends up from a right side of front base wall 1542 of connector base 1507. A left tab 1540 extends up from a left side of front base wall 1542 of connector base 1507.

A right plurality of protrusions 1550 may extend outward from a right side of connector body 1506. The right plurality of protrusions 1550 and the right plurality of tabs 1530 form a first channel within which right arm 1544 of sliding wall 1520 is configured to slide. A left plurality of protrusions 1552 extends outward from a left side of connector body 1506. The left plurality of protrusions 1552 and the left plurality of tabs 1532 form a second channel within which left arm 1548 of sliding wall 1520 is configured to slide.

Right tab 1538, left tab 1540, the right plurality of protrusions 1550, the right plurality of tabs 1530, the left plurality of protrusions 1552, and the left plurality of tabs 1532 mount sliding wall 1520 to connector body 1506 and connector base 1507 while allowing sliding wall 1520 to slide in a horizontal direction to align right blocking aperture walls 1522 and left blocking aperture walls 1524 with right mounting pins 1502 and left mounting pins 1504, respectively, or to align right aperture walls 1526 and left aperture walls 1528 with right mounting pins 1502 and left mounting pins 1504, respectively. Right mounting pins 1502 and left mounting pins 1504 may be spring loaded to be depressed when aligned with right blocking aperture walls 1522 and left blocking aperture walls 1524, respectively, and to be extended when aligned with right aperture walls 1526 and left aperture walls 1528, respectively.

When ladder connector 1500 is mounted to first right ladder 108, front arm 1546 is pressed against a back surface of front wall 1300 of first right ladder 108 aligning right aperture walls 1526 and left aperture walls 1528 with right mounting pins 1502 and left mounting pins 1504, respectively. Right mounting pins 1502 align with and are inserted into a pair of right ladder connector aperture walls 1308, and left mounting pins 1504 align with and are inserted into a pair of left ladder connector aperture walls 1310 to mount ladder connector 1500 to first right ladder 108.

A right compression tab 1554 extends outward from a back portion of right base wall 1543 of connector base 1507. A left compression tab 1802 extends outward from a back portion of left base wall 1800 of connector base 1507. When ladder connector 1500 is mounted to first right ladder 108, right compression tab 1554 presses against an inner surface of right side wall 1302 of first right ladder 108, and left compression tab 1802 presses against an inner surface of left side wall 1304 of first right ladder 108 to further hold ladder connector 1500 in place on first right ladder 108.

When ladder connector 1500 is not mounted to first right ladder 108, right mounting pins 1502 align with and are partially inserted into a pair of right blocking aperture walls 1522, and left mounting pins 1504 align with and are partially inserted into a pair of left blocking aperture walls 1524 to allow ladder connector 1500 to be inserted into first right ladder 108. When ladder connector 1500 is not mounted to first right ladder 108, the partial insertion of right mounting pins 1502 into the pair of right blocking aperture walls 1522 and the partial insertion of left mounting pins 1504 into the pair of left blocking aperture walls 1524 holds sliding wall 1520 in the blocked position until front arm 1546 is pressed against the back surface of front wall 1300 of first right ladder 108 to slide sliding wall 1520 horizontally toward connector body 1506. Again, when sliding wall 1520 is slid horizontally toward connector body 1506, right mounting pins 1502 align with and are inserted into a pair of right ladder connector aperture walls 1308 by action of springs, and left mounting pins 1504 align with and are inserted into a pair of left ladder connector aperture walls 1310 by action of springs to mount ladder connector 1500 to first right ladder 108.

Again, right spring-loaded contact pin 1508 and left spring-loaded contact pin 1510 are positioned to align with contact pad 712 and with second contact pad 1104, respectively, when right bracket 210 is mounted to first right ladder 108. Right spring-loaded contact pin 1508 and left spring-loaded contact pin 1510 are mounted to slide up and down within right cone 1512 and left cone 1514, respectively, when weight is applied to a respective spring-loaded contact pin. Illustrative spring-loaded contact pins are those offered by PRECI-DIP SA of Delémont, Switzerland. Each spring-loaded contact pin may be designed such that it operates in a specific working range to prolong a life of the pin, is plated to prevent corrosion build up, and/or is designed to operate in the conditions to which the interior space of the device is exposed such as the interior space of a freezer, of a wine closet, and/or of refrigerator 100.

Connector base 1507 may further include a center base wall 1904, a right base platform 1906, and a left base platform 1908. Center base wall 1904 extends away from front base wall 1542 generally parallel to and approximately centered between right base wall 1543 and left base wall 1800. Right base platform 1906 extends downward to define a first wire channel between right base wall 1543 and right base platform 1906, through right solder post 1900, and between right base platform 1906 and center base wall 1904. Right wire 1534 is wound within the first wire channel. Left base platform 1908 extends downward to define a second wire channel between left base wall 1800 and left base platform 1908, through left solder post 1902, and between left base platform 1908 and center base wall 1904. Left wire 1536 is wound within the second wire channel. A plurality of protrusions 1910 may extend outward from right base wall 1543, from either side of center base wall 1904, from left base wall 1800, from either side of right base platform 1906, and/or from either side of left base platform 1908 to assist in holding right wire 1534 and left wire 1536 wound around right base platform 1906 and left base platform 1908, respectively.

In the illustrative embodiments of FIGS. 15 and 17 to 21, ladder connector 1500 includes left and right elements because ladder connector 1500 is designed to mate with both first shelf connector 500 and second shelf connector 502. For example, ladder connector 1500 includes both right spring-loaded contact pin 1508 and left spring-loaded contact pin 1510.

Referring to FIG. 30, first shelf connector 500 and second shelf connector 502 are mounted on ladder connector 1500 with first right ladder 108 removed in accordance with an illustrative embodiment. In an alternative embodiment, first shelf connector 500 and/or second shelf connector 502 may be similarly positioned for mounting on second ladder connector 1600. Ladder connector 1500 is mounted to first right ladder 108 by inserting head portion 300 of right bracket 210 into the shelf bracket aperture wall of the plurality of shelf bracket aperture walls 1306. Ladder mounting surface 308 rests on a bottom surface of the shelf bracket aperture wall and second contact pad 1104 of second shelf connector 502 contacts left spring-loaded contact pin 1510 while foot contact surface 316 will abut a top surface of the second shelf bracket aperture wall that is below the shelf bracket aperture wall when mounting of second shelf connector 502 to ladder connector 1500 is complete.

There may be a wiping action on right spring-loaded contact pin 1508 and/or left spring-loaded contact pin 1510 when mounting first shelf connector 500 and/or second shelf connector 502 to ladder connector 1500 or to second ladder connector 1600 to ensure better contact surface conditions for lower contact resistance and to remove possible corrosion that may have built up. Use of spring-loaded contact pins such as right spring-loaded contact pin 1508 and left spring-loaded contact pin 1510 keeps a voltage of the electrical signals applied to contact pad 712 and to second contact pad 1104 isolated from each other and from the interior components of the device such as refrigerator 100. Additionally, neither shelf bracket 210 nor the ladder need to be energized as compared to existing systems. By isolating the bus voltages from each other, all metal interiors, cold plate, ladders, sidewalls, etc. can be used instead of plastic components to provide the insulation.

Referring to FIG. 31, a block diagram of a refrigerator controller 3100 is shown in accordance with an illustrative embodiment for refrigerator 100.
