[0039] Referring now to the drawings, and more particularly to FIGS. 1-7, shown therein is an exemplary embodiment of an appliance door holder 10 constructed in accordance with the inventive concepts disclosed and claimed herein. The appliance door holder 10 has a generally F-shaped body 12 with a spine 14, a first arm 16 extending from a first end 18 of the spine 14, a second arm 20 extending from the spine 14 in the same direction as the first arm 16, and a foot 22 at a second end 24 of the spine 14. A proximal portion 26 of the spine 14 extends between the first arm 16 and second arm 20, and a distal portion 28 of the spine 14 extends between the second arm 20 and the foot 22. As shown in FIG. 7, the first and second arms 16 and 20, respectively, are spaced to receive a door rim 30 of an appliance 32. The foot 22 includes at least one magnet 34 for magnetically attaching to a body 36 or an opening sidewall 38 of the appliance 32.

[0040] In one embodiment, the first arm 16 and the second arm 20 extend in a direction perpendicular to the proximal portion 26 of the spine 14.

[0041] In one embodiment, a distal end 40 of the first arm 16 includes a lip 42 extending inwardly. In use, the lip 42 can be placed to wrap about the door rim 30 to better secure the appliance door 44.

[0042] In one embodiment, the distal portion 28 of the spine 14 angles inwardly from the proximal portion 26 of the spine 14. Many front loaded washing machines, for example, are designed such that the opening sidewall 38 angles from the front exterior 46 of the appliance 32 toward the inner washing chamber 48. The degree of inward angle of the distal portion 28 can be made to approximate or generally follow the angle of the opening sidewall 38 of the appliance 32. While the angle does not need to match exactly, the presence of an angle assists in placement of the appliance door holder 10 and stability of the door holder 10 once placed on the appliance 32 to hold the appliance door 44 in a slightly open position.

[0043] In one embodiment, the at least one magnet 34 is positioned on or near an outer edge 50 of the foot 22. Such placement allows the at least one magnet 34 to magnetically attach to an angled opening sidewall 38.

[0044] In one embodiment, the at least one magnet 34 is positioned on a distal end 52 of the foot 22. Such placement allows the at least one magnet 34 to magnetically attach to an opening edge 54 of the appliance 32.

[0045] In yet another embodiment, a magnet is present at both positions, i.e., at least one magnet 34 is positioned on or near the outer edge 50 of the foot 22 and at least one magnet 34 is positioned on the distal end 52 of the foot 22.

[0046] The at least one magnet 34 can be on an exterior surface 56 of the foot 22, within the foot but partially exposed on the exterior surface 56 of the foot 22, or completely enclosed within the foot 22. Marring or scratching of the appliance surface can be lessened or minimized enclosing the at least one magnet 34 within the foot 22.

[0047] In one exemplary embodiment, the appliance door holder 10 is constructed of two pieces: a base 58 and a lid 60. FIG. 8 and FIG. 9 show multiple views of the base 58 and the lid 60, respectively. A first magnet (not shown) is positioned within containment walls 62 in the base 58. A second magnet is positioned within containment walls 62 in the base 58. To assist in alignment of the base 58 and lid 60, positioning pins 64 and 64 are arranged such that positioning pins 64 in the base 58 comprise an orifice for receiving positioning pins 64 in the lid. The base 58 is attached to the lid 60 using clip components 64 and 64 to achieve a snap fit.

[0048] The one or more magnets 34 can be made of ceramic ferrite, rare earths, and other materials known to those skilled in the art. For example, suitable permanent magnetic materials include strontium ferrite, samarium cobalt, neodymium iron boride, alnico (aluminum, nickel, cobalt). The magnet shape can be a rectangular bar, round bar, disc(s), and the like.

[0049] The appliance door holder 10 can be made of plastic, wood, natural and synthetic rubber, composites, combinations thereof, or other material(s) compatible with the appliance 32. In one embodiment, the appliance door holder 10 is formed of a thermoplastic. Nonlimiting examples of suitable thermoplastics include acrylic, polyethylene, polypropylene, polystyrene, and polyvinyl chloride.

[0050] In one embodiment, the appliance door holder 10 can be made from a thermosetting polymer. Nonlimiting examples of thermosetting polymers include acrylic resins, epoxy, polyurethane, and the like.

[0051] In one embodiment, the appliance door holder 10 is formed of a flexible material. This allows the appliance door holder 10 to deform and recover without breaking when, for example, a person pushes against the appliance door while the appliance door holder 10 is in place. Polymeric materials used for the flexible plastic appliance door holder 10, include but are not limited to, polyolefins, polyesters, polyamides (NYLON) and poly(tetrafluoroethylene) (TEFLON).

[0052] The appliance door holder 10 can be manufactured using processes such as injection molding, press molding, generative fabrication process, and the like.

[0053] In one embodiment, the appliance door holder 10 is manufactured using a generative fabrication process. Examples of suitable generative fabrication processes include, but are not limited to, stereolithography, fused layer modeling, layer laminate manufacturing, 3-D printing, and laser sintering. In one embodiment, the generative fabrication process utilized is 3-D printing.

[0054] Referring now to FIGS. 10-15, shown therein is another exemplary embodiment of an appliance door holder 10a constructed in accordance with the inventive concepts disclosed and claimed herein. The appliance door holder 10a has a generally F-shaped body 12a with a spine 14a, a first arm 16a extending from a first end 18a of the spine 14a, a second arm 20a extending from the spine 14a in the same direction as the first arm 16a, and a foot 22a at a second end 24a of the spine 14a. A proximal portion 26a of the spine 14a extends between the first arm 16a and second arm 20a, and a distal portion 28a of the spine 14a extends between the second arm 20a and the foot 22a. As with the previously described appliance door holder 10 shown in FIG. 7, the first and second arms 16a and 20a, respectively, are spaced to receive a door rim 30 of an appliance 32. The first arm 16a has a length sufficient to extend across the door rim 30 of the appliance 32. The foot 22a includes at least one magnet 34a (FIG. 15) for magnetically attaching to a body 36 or an opening sidewall 38 of the appliance 32.

[0055] In one embodiment, the first arm 16a and the second arm 20a extend in a direction perpendicular to the proximal portion 26a of the spine 14a.

[0056] In one embodiment, a distal end 40a of the first arm 16a includes a catch 68 extending generally inwardly toward the foot. The catch 68 can be triangular extending inwardly and back toward the first arm 16a to form a loop. The triangular catch 68 can include a lip 42a and an opening or eye 70. In use, the lip 42a can be placed to catch the door rim 30 to secure the appliance door 44 between the first arm 16a and the second arm 20a. The eye 70 allows a user to easily grasp the appliance door holder 10a with a single finger, or it can be purely ornamental.

[0057] In one embodiment, a leg 72 extends from a distal end 74 of the second arm 20a to the foot 22a, thereby forming a triangular handle 76 with an opening 78.

[0058] The at least one magnet 34a can be positioned at a distal end 52a of the foot 22a. In one embodiment, placement of multiple magnets 34a, for example four magnets as shown in FIG. 15, on or adjacent a surface 80 of the distal end 52a of the foot 22a, provides a large magnetic surface for attaching to the opening sidewall 38 of the appliance 32.

[0059] The at least one magnet 34a can be on an exterior of the surface 80 of the foot 22a, within the foot but partially exposed on the exterior of surface 80 of the foot 22a, or completely enclosed within the foot 22a. Marring or scratching of the appliance surface can be lessened or minimized by enclosing the at least one magnet 34a within the foot 22a.

[0060] Referring now to FIGS. 17 and 18, in one exemplary embodiment, the appliance door holder 10a is constructed of two main pieces, a base 58a and a lid 60a, as well as a cap 82, a triangular loop piece 84, and a triangular handle piece 86. Magnets 34a are positioned within the cap 82 using a magnet containment wall 62a which is held in place within foot grooves 88 in the base 58a and the lid 60a. To assist in alignment of the base 58a and triangular loop piece 84, positioning pins 64a are arranged such that positioning pins 64a in the base 58 are received by orifices in positioning pins 64a in the lid 60 and the triangular loop piece 84. The base 58 is attached to the lid 60 using clip components 66 and 66 to achieve a snap fit.

[0061] The one or more magnets 34a can be made of ceramic ferrite, rare earths, and other materials known to those skilled in the art. For example, suitable permanent magnetic materials include strontium ferrite, samarium cobalt, neodymium iron boride, alnico (aluminum, nickel, cobalt). The magnet shape can be a rectangular bar, round bar, disc(s), and the like.

[0062] The appliance door holder 10a can be made of plastic, wood, natural and synthetic rubber, composites, combinations thereof, or other material(s) compatible with the appliance 32. In one embodiment, the appliance door holder 10a is formed of a thermoplastic. Nonlimiting examples of suitable thermoplastics include acrylic, polyethylene, polypropylene, polystyrene, and polyvinyl chloride.

[0063] In one embodiment, the appliance door holder 10a can be made from a thermosetting polymer. Nonlimiting examples of thermosetting polymers include acrylic resins, epoxy, polyurethane, and the like.

[0064] In one embodiment, the appliance door holder 10a is formed of a flexible material. This allows the appliance door holder 10a to deform and recover without breaking when, for example, a person pushes against the appliance door while the appliance door holder 10a is in place. Polymeric materials used for the flexible plastic appliance door holder 10a, include but are not limited to, polyolefins, polyesters, polyam ides (NYLON), and poly(tetrafluoroethylene) (TEFLON).

[0065] In one embodiment, the base 58a and lid 60a of the appliance door holder 10a are formed of a material that is different from the material used to form the triangular loop piece 84 and the triangular handle piece 86. Since portions of the triangular loop piece 84 and the triangular handle piece 86 will contact the appliance door 40, in one embodiment the triangular loop piece 84 and the triangular handle piece 86 are made of a softer and more flexible material than the base 58a and lid 60a of the appliance door holder 10a.

[0066] The appliance door holder 10a can be manufactured using processes such as injection molding, press molding, generative fabrication process, and the like.

[0067] In one embodiment, the appliance door holder 10a is manufactured using a generative fabrication process. Examples of suitable generative fabrication processes include, but are not limited to, stereolithography, fused layer modeling, layer laminate manufacturing, 3-D printing, and laser sintering. In one embodiment, the generative fabrication process utilized is 3-D printing.
