Appliances such as ovens, dryers, dishwashers, and the like typically include a pair of hinge receivers connected to a front wall or other part of an appliance body, and a door of the appliance is pivotally connected to the appliance body by a corresponding pair of hinges that are connected to the door and that are also engaged with the respective receivers. In certain applications and circumstances, it is desirable to adjust the operative position of the hinge (and door connected thereto) relative to the appliance body without repositioning a base of the hinge receiver relative to the body. This adjustment is sometimes accomplished by an “adjustable receiver” in which the base of the receiver is connected to the appliance body in a fixed location, and one or more internal hinge engagement or hinge mounting structure(s) of the receiver are selectively adjustable relative to the base of the receiver.
In one such system, the receiver base is mounted to a vertical front wall of an oven and the vertical position of the oven door is adjusted by selectively altering the vertical position of one or more horizontal mounting rivets or other hinge mounting structures connected to the receiver base using an adjustment screw that is manually rotated by a user in clockwise or counterclockwise directions. The adjustable screw is located adjacent the front wall of the appliance body, which necessitates opening the appliance door (and/or a drawer located beneath the door) at least partially in order to rotate the adjustment screw as needed to adjust the position of the door. This has been deemed suboptimal because it requires repeated opening and closing of the door to assess the progress of the door adjustable process. Additionally, when adjusting the oven door position downward, known receivers can stick or jamb since they operate by gravity and do not include any active mechanism for forcing the movable part of the assembly downward. As such, when stuck in position, these known receivers require jostling or removal of the door to allow gravity and/or user manual force to lower the movable inner part of the receiver to which the door is connected. Accordingly, a need has been identified for a new and improved adjustable hinge receiver that overcomes this deficiency while providing other benefits and advantages as set forth below.
In accordance with one aspect of the present disclosure, an adjustable appliance hinge receiver includes a base including spaced-apart first and second lateral walls. A slide body is slidably connected to the base and located between the lateral walls of the base. The slide body is adapted to slide relative to said base along an adjustment axis. At least one hinge mounting structure is connected to the slide body and adapted to be engaged by an associated hinge. An adjustment system includes a first inclined ramp connected to the slide body. The adjustment system includes an adjustment shaft extending between and rotatably supported by the first and second side walls of the base. The adjustment shaft is rotatable relative to said base about an axis of rotation. The adjustment system also includes an adjustment member engaged with the adjustment shaft and selectively movable axially along the axis of rotation in opposite first and second directions in response to rotational movement of the adjustment shaft about the axis of rotation in opposite first and second rotational directions such that rotation of the adjustment shaft in one of the first and second rotational directions causes the adjustment member to bear against the first ramp and induce sliding movement of the slide body relative to the base along said adjustment axis.
The door D pivots relative to the body B about a horizontal pivot axis X (
The appliance body B also includes left and right side walls LW,RW located on the left and right lateral sides of the body B, respectively. The left and right hinge assemblies LH,RH are connected respectively to left and right lateral sides of the door D and mate respectively with left and right adjustable hinge receivers LR,RR that are each adjustable receivers formed in accordance with the present development as described herein (although the illustrated embodiment includes both left and right adjustable hinge receivers LR,RR provided in accordance with the present development, only one adjustable receiver constructed in accordance with the present development needs to be included, and the other receiver can be a standard non-adjustable or adjustable receiver). The left and right hinge receivers LR,RR are connected to the body B and are respectively located adjacent the left and right side walls LW,RW and respectively adjacent the opposite left and right lateral sides of the chamber C.
When the door D is in the closed position as shown, the left and right hinge receivers LR,RR are covered by the door D. In contrast to known adjustable receivers, however, the adjustable receivers LR,RR provided according to the present invention are accessible and operable to adjust the vertical position of the door D (for a door D that pivots about a horizontal pivot axis X) when the door D is in its closed position (or when the door is in an opened position) through access openings AO (
The left and right hinge assemblies LH,RH are conventional and can be provided in any of a variety of well-known designs that are adapted to mate the left and right adjustable receivers LR,RR, respectively. As described below, the adjustable receivers LR,RR can be modified slightly in different embodiments so as to be configured to mate with different styles of known hinge assemblies LH,RH. Also, the left and right adjustable receivers are described below with primary reference to the right adjustable receiver RR. The left adjustable receiver LR can have the identical structure as the right adjustable receiver RR provided that the lead screw 34 (described below) is oriented in an opposite direction for input of torque thereto via opening AO as required to rotate the lead screw 34 to adjust the receiver LR. Alternatively, the left adjustable receiver LR can be provided as a mirror image of the right adjustable receiver RR or is otherwise correspondingly structured.
It can be seen in
The front wall 16 includes an access opening 16s such as a slot, notch, aperture, or other void that opens therethrough and into the space S10. The front wall access opening 16s is adapted to receive a mounting arm MA of the hinge assembly RH such that the mounting arm MA extends into the space S10 between the side/lateral walls 12,14 as required for the hinge assembly RH to be operably connected to mounting structures of the adjustable receiver RR as described further below. In one embodiment, the base 10 comprise a one-piece metal structure such as a stamped steel structure, but other metallic and/or non-metallic (e.g., polymeric) materials and other forming methods can be used to construct the base 10.
As best seen in the exploded view of
In the illustrated embodiment, the inner slide member 20 comprises first and second parallel, spaced-apart side walls 22,24 connected to each other by a front wall 26 such that the inner slide member 20 comprises an open space S20 located between the side walls 22,24 and front wall 26. The inner slide member 20 thus defines a U-shaped cross-section. The front wall 26 of the inner slide member 20 is abutted with or otherwise arranged adjacent the front wall 16 of the base 10 and includes an opening 26s defined therein such as a slot, notch, aperture, or other void that opens therethrough and into the space S20. When the inner slide member 20 is operatively connected to the base 10 and nested in the space S10 between the base lateral walls 12,14, the opening 26s in the front wall 26 of the inner slide member 20 is at least partially aligned or registered with the opening 16s in the front wall 16 of the base 10, and the first side wall, second side wall, and front wall 22, 24, 26 of the inner slide member 20 lie respectively adjacent and slidably abut the first lateral wall, second lateral wall, and front wall 12, 14, 16 of the base 10. In one embodiment, the inner slide member 20 comprise a one-piece metal structure such as a stamped steel structure, but other metallic and/or non-metallic (e.g., polymeric) materials and other forming methods can be used to construct the inner slide member 20.
As noted above and as shown in
In the illustrated embodiment, the mounting arm MA of the hinge assembly RH includes an optional pivoting latch L that is selectively manually pivotable into the illustrated operative position to engage the second mounting structure MT2 to operatively capture the mounting arm MA to the adjustable receiver after the first and third mounting structures MT1,MT3 are engaged by respective slots MS1,MS3 of the mounting arm MA. The latch L thus prevents inadvertent separation of the mounting arm MA (and hinge assembly RH) from the adjustable receiver RR by preventing the slots MS1,MS3 from being disengaged from the respective mounting structures MT1,MT3 of the adjustable receiver RR. It should be noted that the base 10 includes a first (lower) end 10a and an opposite second (upper) end 10b, wherein the mounting structures MT are located closer to the first end 10a of the base 10 as compared to the second end 10b of the base 10. The latch L is optional and can be omitted such as on hinges where there is no reversal of force that would tend to dislodge the mounting arm MA from the slide member 20. Alternatively, a screw, fastener, clip, and/or other secondary attachment device can be used to directly or indirectly connect the mounting arm MA to the slide member 20.
Referring again to
In the illustrated embodiment, the lateral walls 12,14 of the base 10 each include first (lower) and second (upper) clearance openings CO1,CO2 that allow for installation of the first and second mounting structures MT1,MT2 after the inner slide member 20 is installed in the space S10 between the lateral walls 12,14 of the base 10. The first and second clearance openings CO1,CO2 are each elongated at least along the adjustment axis AX or otherwise enlarged to allow for movement of the projecting ends of the first and second mounting structures MT1,MT2 during movement of the inner slide member 20 relative to the base 10 in the first and second directions D1,D2. In the embodiment shown herein, the clearance openings CO1,CO2 are conformed and dimensioned to limit movement of the first and second mounting structures MT1,MT2 therein in any direction except along the adjustment axis AX to further control and limit the path of movement of the inner slide member 20 relative to the base 10 and to further strengthen the assembly of the inner slide member 20 to the base 10 to resist any forces that might tend to urge the inner slide member 20 away from the front wall 16 of the base 10.
With reference also to the rear views of
The inclined adjustment channel AC defined between the first and second ramps R1,R2 includes a first or low side or low end ACL and a second or high side or high end ACH. The first/low end ACL of the adjustment channel AC is located closer to the hinge mounting structures MT (MT1,MT2,MT3) (i.e., located closer to the first end 20a of the slide member 20) because it is defined between the respective first or low ends of the ramps R1,R2 that are located closer to the hinge mounting structures MT (MT1,MT2,MT3) (i.e., located closer to the first end 20a of the slide member 20) as compared to their respective opposite ends. Correspondingly, the second/high end ACH of the adjustment channel AC is located closer to the second slide fastener SF2 (i.e., closer to the opposite, second end 20b of the slide member 20 that is spaced from the first end 20a of the slide member 20 and spaced from the hinge mounting structures MT) because it is defined between the respective second or high ends of the ramps R1,R2 that are located farther away from the hinge mounting structures MT (MT1,MT2,MT3) (i.e., located closer to the second end 20b of the slide member 20) as compared to the opposite ends of the ramps R1,R2. An adjustment member 36 or at least a part thereof is closely received in the adjustment channel AC between and operably engaged with the first and second ramps R1,R2 and its position relative to the first (low) and second (high) ends ACL,ACH of the adjustment channel AC, as controlled by the adjustment system 30, determines the axial location of the inner slide member 20 relative to the base 10 along the adjustment axis AX.
With continuing reference to
In the illustrated embodiment, the adjustment system 30 further comprises a cam adjustment system comprising a rotatable adjustment shaft or adjustment screw such as lead screw 34 and the adjustment member 36 that is threadably engaged with the adjustment screw/lead screw 34. More particularly, in the illustrated embodiment, the lead screw 34 comprises a helically threaded shaft that extends along an axis of rotation RX through the lateral walls 12,14 of the base 10 and through the space S10 between the first and second lateral walls 12,14 of the base 10. Alternatively, the lead screw or other adjustment shaft comprises a cam profile or other projection(s) that extend around the axis of rotation RX. The lead screw 34 also extends along the axis of rotation RX through the side walls 22,24 of the slide member 20 and through the space S20 of the slide member 20. The lead screw 34 is rotatably supported by (but not threadably engaged with) the first and second lateral walls 12,14 of the base 10. The lead screw 34 extends through enlarged first and second slots, notches, or openings W22,W24 (
The lead screw 34 extends along and is rotatable about the axis of rotation RX. In the illustrated embodiment, the lead screw 34 comprises a bolt 35 including a threaded shank 35s, a driving head 35h, and a nut 35n threaded or otherwise secured on the shank 35s. The head 35h defines a hexagonal or other non-circular shape suitable for rotating the bolt about its axis of rotation RX by a wrench or other tool engaged with the head 35h. The head 35 can alternatively or additionally include a slot, recess, or other internal drive structure such as a Torx, hexagonal (hex), Phillips, slot, and/or other internal drive structure 35d (
The adjustment member 36 is threadably engaged with the lead screw 34 (with the threaded shank 35s of the bolt 35 in the illustrated embodiment) and located in the space S20 between the side walls 22,24 of the inner slide member 20 in the adjustment channel AC adjacent the first and second ramps R1,R2 such that rotation of the lead screw 34 in a first (counter-clockwise) direction about its axis of rotation RX relative to the adjustment member 36 causes axial linear translation of the adjustment member 36 in the adjustment channel AC along the axis of rotation RX of the lead screw 34 in a first direction toward the first side wall 22 of the slide member 20 (toward the high end ACH of the adjustment channel AC in the illustrated embodiment) and such that rotation of the lead screw 34 in a second (clockwise) direction that is opposite the first direction relative to the adjustment member 36 causes linear translation of the adjustment member 36 in the adjustment channel AC along the axis of rotation of the lead screw 34 in an opposite, second direction toward the second side wall 24 of the inner slide member 20 (toward the low end ACL of the adjustment channel AC in the illustrated embodiment). Movement of the adjustment member 36 toward the high end ACH of the adjustment channel AC (toward the first side wall 22 of the slide member 20) causes the adjustment member 36 to bear against the ramp R2 and urge the slide member 20 downward toward the first end 10a of the base 10. Movement of the adjustment member 36 in the opposite direction toward the low end ACL of the adjustment channel AC (toward the second side wall 24 of the slide member 24) causes the adjustment member 36 to bear against the upper ramp R1 and urge the slide member 20 upward toward the second end 10b of the base 10. Furthermore, the axis of rotation RX of the lead screw 34 is beneficially oriented parallel to the first and second mount axis MX1,MX2 to overcome some of the above-noted deficiencies of prior adjustable hinge receiver designs. In the case where the lead screw 34 comprises a cam profile rather than a helical thread, the adjustment member 36 is engaged with the cam profile according to a cam-follower relationship whereby rotation of the lead screw 34 about its axis of rotation RX in opposite first and second rotational directions (clockwise/counter-clockwise) induces axial movement of the adjustment member 36 along the axis of rotation RX in corresponding first and second axial directions, respectively. In general terms, as used herein the terms “adjustment screw,” “adjustment shaft,” or “lead screw” are each intended to encompass any rotational shaft that is mechanically engaged with the adjustment member 36 such that rotation of the shaft 34 about its axis of rotation RX in opposite first and second rotational directions induces axial movement of the adjustment member 36 along the axis of rotation RX in corresponding first and second axial directions, respectively.
The second, lower ramp R2 can optionally be omitted from the ramp structure R in which case the slide member 20 moves downward toward the first end 10a of the base 10 by force of gravity when the adjustment member 36 moves toward the first side wall 22 of the slide member 20, but it is desirable to include the second/lower ramp R2 so that the adjustment member 36 actively forces the slide member 20 downward when the adjustment system 30 is operated to move the adjustment member 36 in the first direction toward the first slide wall 22 of the slide member 20 rather than relying on gravity to move the slide member 20 downward, since a gravity operated system is more likely to stick or jamb due to the natural rotational torque applied to the slide member 20 from the weight of the door D, or if out of alignment or obstructed.
The lead screw 34 and adjustment member 36 can be either right-hand threaded (as shown) or left-hand threaded as desired to select the directions of rotation (clockwise or counter-clockwise) that induce the first and second directions of linear translation of the adjustment member 36 between the slide member side walls 22,24.
The adjustment member 36 is shown herein as a rectangular plate structure but can alternatively be provided in any desired shape, size, and structure such as a nut, block, winged structure or other member that is threaded onto the lead screw 34. In addition to being threadably engaged with the lead screw 34, the adjustment member 36 slidably supported in the space S20 and prevented from rotating with the lead screw 34 relative to the slide member 20 and base 10 by a or support arm or support shaft 38 such as a rod, pin, or rail that extends through or that is otherwise slidably engaged with the adjustment member 36. The support arm/shaft 38 is arranged parallel to the axis of rotation RX and is arranged parallel to and spaced-apart from the lead screw 34. The adjustment member 36 is slidably supported on the support shaft 38 for movement on the support shaft toward and away from the side walls 22,24 of the slide member 20. As shown herein, the adjustment member 36 includes an aperture 36a (
The ramps R1,R2 can alternatively be inclined in the opposite direction to that shown herein, for example, to provide a left adjustable receiver LR. As noted above, the left adjustable receiver LR can also be provided by simply reversing the orientation of the lead screw 34 (bolt 35) and nut 35n so that the head 35h lies adjacent the first side wall 12 of the base 10 instead of the second side wall 14 of the base 10 as shown in
