Definitions

  • This invention relates to shelving for refrigerators and similar appliances. More particularly, the present invention further relates to slide brackets for storage bins, drawers, pans, or other sliding members which are commonly used with refrigerator shelving.
  • Refrigerator shelving has evolved from fixed wire racks or even adjustable racks supported by simple brackets or pegs projecting from the interior walls of a refrigerator compartment, to the complex shelving units now widely available and commonly used in refrigerators. This evolution has been spurred by competitive refrigerator vendors seeking to make their products more adaptable and convenient to the needs and uses of each consumer. The result is numerous task or function specific shelf assemblies of varying width and comprising a variety of slidable drawers, storage bins, pans, etc. which are typically mounted under the shelf panel.
  • the commonly known refrigerator shelf assembly is also typically task-specific.
  • a shelf assembly directed to supporting articles thereon is not readily convertible to the added task of providing under shelf sliding storage with a bin or drawer for example.
  • a shelf assembly directed to providing a sliding member under the shelf panel is also not commonly adaptable to the singular task of providing only a shelf. While the sliding member may often times be removed and set aside, the slides themselves which support the sliding member under the shelf panel are typically an integral part of the shelf assembly and may not be easily removed, but must remain, typically projecting downward from the shelf assembly and interfering with items stored on adjacent shelving, below the subject shelf panel.
  • the present invention addresses this evolution of expense and complexity and seeks to provide a uniquely simple refrigerator shelf assembly having versatility to easily overcome or at lease mitigate these problems.
  • a shelf assembly suitable for a refrigerator, the assembly comprising: a shelf panel having a front edge and a back edge; a front rim extending along (or across) at least a portion of the front edge and having a portion below the shelf panel that is provided with a front slide attachment means; a back rim extending across at least a portion of the back edge and having a portion below the shelf that is provided with a back slide attachments means; and the shelf assembly being adapted for receiving and supporting a sliding member in sliding engagement under the shelf panel, the slide being removably secured to both the front and back attachment means.
  • the front rim and/or back rim will extend below the shelf panel. They may define, respectively, at least one front slide receptacle and at least one back slide receptacle. It will be appreciated that preferred embodiments for each attachment means is suitably a receptacle, such as a recess.
  • the slide can preferably be removably coupled with the front slide receptacle and the back slide receptacle, in preferred embodiments.
  • the shelf assembly is preferably provided with at least one slide.
  • the slide will suitably be adapted for receiving, supporting and allowing sliding motion of one or more sliding members.
  • Sliding members include storage bins, drawers, pans or other suitable container capable of containing or supporting one or more items that are intended to be kept in the refrigerator.
  • the or each slide (one may be sufficient but in some situations a plurality will be preferred, suitably a pair) can be removably secured in a number of different positions which may allow the accommodation of different sliding members which may be of different widths.
  • the or each slide may be positioned at a particular distance apart to allow a certain sliding member to be accommodated. The flexibility of movement of the slides allows sliding members of varying width to be used with the shelf assembly invention.
  • each front and rear (or back) attachment means may take the form of, in conjunction with the slide, male and female co-operating members. It is preferred, although it is not essential that the slide is provided with one or more male members while suitable co-operating female members are provided on the shelf assembly, usually in the front and/or back rim, as appropriate.
  • the male members may take the form of bosses, protrusions or other suitable projections, while the female member may be in the form of a groove, channel, recess, receptacle or aperture suitable for receiving the male member.
  • the or each slide has: an elongate body portion with an opposing front and back (or rear) ends; a front attachment member (e.g. a male member) adapted for releasable engagement with the front slide attachment means (or front slide receptacle) projecting from a front end; and a back attachment member (e.g. a female member) adapted for releasable engagement with the back slide attachment means (e.g. the back slide receptacle) projecting from the back end.
  • a front attachment member e.g. a male member
  • back slide attachment means e.g. the back slide receptacle
  • the front attachment means suitably comprises a recess in the front rim, such as having an open side facing towards the back edge.
  • the back attachments means suitably comprises a recess, such as in the back rim, preferably having an open side facing towards the front edge.
  • Each front and back attachment members preferably have a generally rectangular shape in cross-section and each front and back slide attachment means may have a corresponding rectangular shape in cross-section.
  • attachment member and slide receptacle shapes in cross-section are wider than they are thick, that is to say with the width positioned generally parallel with the shelf panel.
  • the back slide attachment means preferably has a retainer for retaining the back attachment member in it.
  • the shelf panel is tempered glass and each of the front rim and back rim comprises a resinous plastics material. For aesthetic reasons it is sometimes preferred that at least one of the front and back rims is flush with a top surface of the shelf panel.
  • the shelf assembly further comprises at least a pair of shelf brackets for supporting the shelf panel. These brackets may be adapted for attachment inside the refrigerator.
  • the shelf assembly may be provided with a perimeter rim which incorporates the front and back rims.
  • the perimeter rim may thus circumscribe the shelf assembly and may also project above (a top surface of) the panel to define a spill dam, in order that any liquid disposed or spilled upon (the top surface of) the panel may be contained by the perimeter rim.
  • the shelf panel, the front rim, the back rim (or the perimeter rim where present) and the or each shelf brackets (when present) are one piece.
  • the back slide receptacle preferably includes a retainer for resisting uncoupling of the slide from the back slide receptacle.
  • a shelf assembly for a refrigerator comprising: a one piece shelf member having a shelf panel, a front rim and a back rim; the shelf member having a front edge and a back edge; the front rim extending across at least a portion of the front edge, extending below the shelf panel, and defining at least one front slide receptacle; the back rim extending across at least a portion of the back edge, extending below the shelf panel, and defining at least one back slide receptacle; and at least one slide for receiving and supporting a separate member in sliding engagement under the shelf panel, the slide being removably coupled with the front slide receptacle and the back slide receptacles.
  • this may incorporate not only each of the front and back rims, but also at least a pair of shelf brackets (for supporting the shelf member).
  • the invention thus also extends to a shelf assembly for a refrigerator having a shelf panel, a front rim extending below the shelf panel, a back rim extending below the shelf panel, the assembly having one or more slides, the or each slide comprising: and elongate member adapted for releasable coupling with each of the front rim and back rim; means defining a co-operating front slide receptacle in the front rim for releasably coupling with the elongate member; and means defining a co-operating back slide receptacle in the back rim for releasably coupling with the elongate member.
  • the rim comprises a mouldable material and may be made using a mould.
  • a second aspect of the invention relates to a refrigerator provided with one or more shelf assemblies in accordance with the first aspect.
  • refrigerator encompasses chambers or containers in which food, drink or other edible substances are to be cooled or to be kept cool, and includes freezers.
  • Other features and characteristics of the second aspect are as for the first aspect mutatis mutandis.
  • the present invention provides a simplified snap-in slide unit for enhanced versatility of a refrigerator shelf assembly.
  • the shelf assembly includes a shelf panel with a front rim portion extending across at least a portion of a front edge of the panel and extending below the panel wherein a front slide receptacle is defined and with a back rim portion extending across at least a portion of a back edge of the panel and extending below the panel wherein a back slide receptacle is defined.
  • the slide can be removably coupled with the front and back slide receptacles, suitably for receiving and supporting a bin or other sliding member under the shelf panel.
  • the slide has an elongate body portion with a front attachment member projecting from a front end of the elongate body and with a back attachment member projecting from an opposing back end of the elongate body.
  • the front and back slide receptacles are defined by a recess in each of the front and back rims of the shelf assembly, respectively.
  • the front slide receptacle may have an open side toward the back edge of the shelf panel and the back slide receptacle can have an open side toward the front edge of the panel.
  • the shelf assembly is moulded in one piece.
  • the present invention may provide a simplified shelf assembly with a snap-in slide.
  • Versatility of the shelf assembly can be enhanced by the ease with which the slide may be provided to the shelf support a sliding member under the shelf and the ease of removing the slide.
  • One or more slides may be present: a pair of slides for supporting a slide member may be uniformly spaced for use of standard width slide members, regardless of the shelf assembly width. If a plurality of slide receptacles are provided, then the position of the slide member relative to the shelf assembly may also be easily adjusted.
  • the use of a slide can also reduce manufacturing costs.
  • the slide may be conveniently moulded in a one-step process.
  • the slide may also be well-suited to use with a shelf having a moulded rim and is especially suited for use with a one-piece, moulded shelf assembly.
  • Such a slide arrangement may further suppress costs by reducing inventory requirements of shelf assemblies to meet a variety of needs.
  • a refrigerator shelf assembly 10 comprises a generally planar shelf member 12, metal support brackets 14 and 16 and a moulded, resinous perimeter rim 18. Shelf assembly 10 is preferably cantilevered forward by brackets 14 and 16 from the rear wall 20 of a refrigerator.

  • the relative position of clip 410 will determine the extension of shelf member 112.
  • Clip 410 is preferably bent from a strap of steel or formed from other resilient material so that the clip 410 will deform when forced past the cross brace and will resume its original configuration once past the cross brace.
  • Clip 410 is preferably removably mounted to the perimeter rim 118 by a screw 414 so that it can be removed rather than requiring that it be forced past the cross brace during assembly and disassembly of the shelf assembly 110.
  • the shelf assembly can be removed from tracks 44 and disassembled.
  • a fourth embodiment of a shelf stop is shown in Figs. 18 to 20 and comprises a detent 510 pressed out of the side 178 of at least one of the slide rails 168 and 170 and a corresponding groove or channel 512 cut or moulded into the side of the corresponding slide guide 164 and 166.
  • the relative position of detent 510 and the relative position and length of channel 512 will control the extension of shelf member 112.
  • the brackets with slide rails 168 and 170 are assembled to shelf 112 such that detent 510 is received in channel 512 prior to mounting the entire assembly in tracks 44.
  • a fifth embodiment of a shelf stop is shown in Figs. 21 to 23 and comprises a detent 610 projecting from the end of a flexible finger 612 formed in at least one of the slide rails 168 and 170 and a notch 614 cut or moulded into the side of the corresponding slide guide 164 and 166. Again, the relative positioning of the detent and notch will determine the extension of shelf member 112.

  • a plurality of cooperating front and back slide receptacles 846, 852 may also be provided along each of front rim portion and back rim portion 824, 826, respectively, so that slides 828 may be positioned along the length of front and back rim portions 824 and 826.
  • a slide member (not shown) supported by slides 828 may selectively be positioned along the width of the shelf assembly 820, and slide members of various widths may be accommodated.
  • Slide 828 is an elongate member with opposing front and back ends 864 and 866, respectively (Fig 30).
  • a tab 868 extends from front end 864 and forms a front attachment member having a generally rectangular cross-sectional shape corresponding to front slide receptacle 846.
  • a back tab 870 extends from back end 866, forming a back attachment member having a generally rectangular cross-sectional shape corresponding to back slide receptacle 852.
  • a body portion of slide 828 is defined by a generally vertically oriented plate portion 872 and a pair of vertically spaced rails 874 and 876 projecting generally perpendicularly to vertical plate 872 and in the same general direction from one side of vertical plate 872 (Fig. 34).
  • Vertical plate 872 and the rails 874, 876 define an open-sided, open-ended slide track 878 for receiving and supporting a cooperating slide member 880 of a storage bin, drawer, pan, or other separate member for use in the refrigerator.
  • Rail 876 includes downwardly curved ends so that the supported slide member, bin, or drawer can more easily be slid into place.
  • the upper rail 874 merges with front and back tabs 868 and 870 at each of the ends 864, 866 of slide 828, respectively.
  • slide 828 is symmetrical end to end and eliminates the need for left- and right-hand counter parts.
  • a slide 828 is easily installed by positioning the front and back tabs 868, 870 of slide 828 parallel to, adjacent, and under shelf panel 822, inserting front tab 868 into a front slide receptacle 846, and swinging back tab 870 through open side 858, past retainer 860, and into a corresponding back slide receptacle 852. As back tab 870 is swung past retainer 860, slide 828 snaps into place generally parallel with bracket 830. Slide 828 is simply removed by reversing the installation steps. Since slide 828 is preferably symmetrical end to end so that left-hand and right-hand side slides are not necessary, an identical unit may be installed in either a left-hand or right-hand position.
  • a fourth embodiment of a shelf assembly 920 is shown in Fig. 35 and includes a shelf panel 922, a front rim portion 924, a back rim portion 926 and a pair of slides 828.
  • Shelf assembly 920 is preferably used as a bottom refrigerator shelf and may be positioned in a cooperating recess 930 provided at the bottom of a refrigerator as shown in Fig. 35, or may be supported by other methods commonly known in the refrigerator shelf field.
  • Shelf assembly 920 is most preferably moulded in one piece from a mouldable material as discussed above.
  • a perimeter rim 942 including front portion 924 and back portion 926, may be moulded to project above a top surface of shelf panel 922 to form a spill dam.
  • the rim is moulded flush with the top surface of shelf panel 922 as shown in Figure 35.
  • the perimeter rim 942 includes at least a lower portion 944 which extends below shelf panel 922.
  • shelf assembly 920 also has front slide receptacles 946 and back slide receptacles 952 defined in front rim portion 924 and back rim portion 926, respectively, for releasably coupling with slide 828.
  • FIG. 37 A fifth embodiment of a shelf assembly 950 is shown in Figure 37.
  • Shelf assembly 950 includes a shelf panel 952, a front rim 954, and a back rim 956. Shelf assembly 950 may be used as a bottom refrigerator shelf and supported by a variety of methods in a bottom shelf position, including a cooperating recess 930 provided at the bottom of a refrigerator as shown in Fig. 37 for example.
  • Shelf panel 952 is preferably optically clear tempered glass or other light-transmitting material to enhance light distribution through the refrigerator compartment.
  • Shelf panel 952 has a perimeter edge 958 which is preferably encapsulated by a perimeter rim 960 (Fig. 38) .
  • Rim 960 incorporates front rim 954 and back rim 956 and is moulded around perimeter edge 958 of shelf panel 952. Shelf panel 952 is held in position within a mould during assembly while a mouldable material is injected and flows into the mould around perimeter edge 958 as discussed previously in greater detail. Rim 960 is moulded to extend above shelf panel 952, specifically to form a spill dam for containing spills which may occur upon shelf member 950 (Figs. 37 and 38).
  • Rim 960 includes a lower portion 962 which extends below shelf panel 952.
  • Shelf assembly 950 also includes front slide receptacles 846 and back slide receptacles 852 defined in front rim 954 and back rim 956, respectively, for releasably coupling with slide 828 as previously discussed in greater detail regarding shelf assembly 820.
