DETAILED DESCRIPTION
Referring to FIGS. 01:01 and 01:02, a mounting device used for suspending a cabinet door to be painted comprises a rotatable hub (Part “A”), a collar part (Part “B”), a support rod (Part “C”), one or more O-rings (Part “D”), a cover portion (Part “E”) and a support rod sleeve (Part “F”). Part A is displayed in the unlocked position/orientation (0°). Parts A and B are displayed separately for purpose of clarity. In an illustrative embodiment, parts A and B are selective laser sintering (SLS) 3D printed as a captive set, yet free to rotate independently of one another. In the illustrative embodiment of FIG. 01:02, one of two O-rings (Part D) is depicted.
The rotatable hub A comprises one or more internal raised dimples 0030 to provide for a friction fit when the support rod C (also referred to herein as a “handle”) is inserted into opening 0040 (also referred to herein as a “handle slot”). In illustrative embodiments, during manufacturing of the rotatable hub A, material adjacent the opening 0040 (e.g., pockets of material) is removed to facilitate insertion of support rod C into opening 0040 and also save material and/or three-dimensional (3D) printing costs.
Rotatable hub A further includes two notches 0050 on opposite sides of the rotatable hub A to receive corresponding tabs 0010 on an inside surface of cover portion E. The mating (e.g., interlocking) of the notches 0050 and the tabs 0010 secures the cover portion E, which functions as a paint shield, to the rotatable hub A. In order to remove the cover portion E from the rotatable hub A, the cover portion E can be squeezed in a horizontal direction to release the tabs 0010 from the notches 0050 and lifted vertically off of the rotatable hub A. Horizontal and vertically in this instance assume a particular orientation of the cover portion E and rotatable hub A. It is to be understood that the orientation may vary, in which case, horizontal and vertical designations may need to be changed to suit a current orientation of the mounting device. The cover portion E comprises a rectangular opening 0020, which corresponds to the rectangular opening 0040 in the rotatable hub A to receive the support rod C therethrough when the openings 0020 and 0040 are aligned. Although depicted a rectangular, the openings 0020 and 0040 are not necessarily limited to a rectangular shape, and may comprise a different shape (e.g., square) to accommodate a support rod C also having a shape other than rectangular.
Referring to FIGS. 02:01 to 02:06, a cabinet door (e.g., kitchen cabinet door) comprises a hinge hole such as, for example, an industry standard 35 mm diameter hinge hole commonly associated with what is referred to as a European hinge or “cup” hinge (see FIG. 02:01). The mounting device comprising the rotatable hub A and the collar portion B is inserted into the hinge hole as shown in FIG. 02:02. The collar part B comprises one or more grooves 0120 to receive and secure respective O-rings D in place. As can be seen more clearly in FIGS. 04:01 and 04:03, the grooves 0120 include multiple raised portions (e.g., “ribs”) to create a sine wave-like distortion of the O-rings D. The O-rings D resist torque and increase friction when the mounting device is secured in the hinge hole. In a non-limiting illustrative embodiment, the O-rings D comprise square-profile oil resistant buna-O-rings by McMaster Carr part number #4061t13, which can be installed on the collar part B by an end user.
Referring back to FIGS. 02:01 to 02:06, and to FIGS. 05:03, 05:04 and 06:02, in order to secure the mounting device in the hinge hole, the rotatable hub A is rotated a designated number of degrees (e.g., 90 degrees), wherein rotating the rotatable hub A causes respective ones of a plurality of portions 0150 protruding from the rotatable hub A to press against respective ones of a plurality of ramp portions 0160 on an interior surface of the collar part B and exert a force on the collar part B which increases a dimension (e.g., diameter or width) of the collar part B so that the collar part B is tightly fitted in the hinge hole. As can be seen, for example, in FIGS. 05:03 and 05:04, the ramp portions 0160 comprise wall portions of the collar part B which incrementally increase in thickness on an interior side of the collar part B and in a direction of rotation of the rotatable hub A. As can be seen in FIGS. 05:03 and 05:04, each of the ramp portions 0160 begins at a first stepped portion S1, and ends at a second stepped portion S2. The first stepped portion S1 is smaller (e.g., having less thickness) than the second stepped portion S2, which has a greater thickness than the first stepped portion S1. As can be seen in FIGS. 05:03 and 05:04, the protruding portions 0150 comprise areas (e.g., lobes) of increased diameter of the rotatable hub A. Each of the protruding portions 0150 start/end at stepped portions S3 and S4. In an illustrative embodiment, as can be seen in FIGS. 05:03 and 05:04, when in the unlocked position (e.g., 0°), the rotatable hub is prevented from rotating in one direction (e.g., clockwise or counterclockwise depending on view) by engagement of second stepped portions S2 on the ramp portions 0160 with stepped portions S4 on the protruding portions 0150.
In an illustrative embodiment, a small amount of lubricant (e.g., petroleum jelly) is initially applied to surfaces of the protruding portions 0150 and ramp portions 0160. Lubricant can be used for an initial “break-in,” period and handle (support rod C) is temporarily used to aid with locking. Once the “break-in” period is completed, use of the handle may not be necessary.
Increasing the dimension of the collar part B causes the O-rings D disposed around the exterior side of the collar part B to contact an inside wall of the hinge hole. The mounting device (e.g., diameter or width of the collar part B) is dimensioned to be insertable into and removeable from a hinge hole in a cabinet door when the rotatable hub A is in a first position without the respective ones of the plurality of protruding portions 0150 pressing against the respective ones of the plurality of ramp portions 0160. The mounting device (e.g., diameter or width of the collar part B) is dimensioned to be secured in the hinge hole in the cabinet door when the rotatable hub A is in a second position where the respective ones of the plurality of protruding portions 0150 are pressing against the respective ones of the plurality of ramp portions 0160. The protruding portions 0150 (also referred to herein as “lobes”) on the rotatable hub A are configured to apply a predetermined linear force on the plurality of ramp portions 0160, which is, for example, applied in a direction parallel to an edge of the cabinet door when fully engaged (e.g., upon 90° rotation) (sec FIG. 03:03). The plurality of ramp portions 0160 receive the force applied by the plurality of protruding portions 0150, which is transmitted the O-rings D, binding the mounting device to the hinge hole wall. Referring, for example, to FIGS. 01:01, 04:03, 05:03, 05:04, 06:02-06:04 and 08:06, the collar part B comprises one or more relief slots 0130 to permit the increase of the dimension of the collar part when the force is exerted on the collar part B. The collar part B is formed from a flexible material to enable the increase in dimension of the collar part B so that the collar part B is wedged in the hinge hole as a result of the O-rings D contacting the wall of the hinge hole at multiple points of contact.
In a non-limiting illustrative embodiment, the collar part B comprises nylon (PA12) and is 3D selective laser sintering (SLS) printed. In addition, in a non-limiting illustrative embodiment, the rotatable hub A, cover portion E and support rod sleeve F also comprise nylon (PA12) and are 3D SLS printed. Referring to FIGS. 01:01, 03:03, 04:01, 04:03, 04:04, 05:01, 05:02, 07:01, 07:02, 07:04 and 07:05, the rotatable hub A includes a groove 0080 to facilitate 3D printing of the rotatable hub A and collar part B to meet and/or exceed 3D printing loose shell minimum required tolerances. Referring to FIGS. 01:02, 03:03, 04:02, 04:04, 06:01, 07:03, 07:02, 07:06 and 15:09, the rotatable hub A further includes hollowed out portions or voids 0170 where applicable for material stability, to save material and/or lower printing costs. In FIGS. 07:03 and 7:04, rotatable hub A (part A) is depicted in the unlocked position(0°) and in FIGS. 07:01-07:06, collar part B is not shown.
The rotatable hub A is rotated the designated number of degrees with respect to the collar part B until respective ones of the one or more first stop portions 0090 on the rotatable hub part engage with respective ones of the one or more second stop portions 0100 on the collar part B and stop rotation of the rotatable hub part A. In an illustrative embodiment, referring to FIGS. 01:01, 06:03 and 06:04, the first stop portions 0090 include two stepped portions (e.g., “bump stops”) on an exterior side of the rotatable hub A to prevent over rotation of the rotatable hub A beyond the designated number of degrees (e.g., 90°) when the rotatable hub A is turned to a locked position where the first stop portions 0090 make contact with the second stop portions 0100. In an illustrative embodiment, referring to FIGS. 01:01, 06:03 and 06:04, the second stop portions 0100 include two stepped portions (e.g., “bump stops”) on an interior side of the collar part B to prevent over rotation of the rotatable hub A beyond the designated number of degrees (e.g., 90°) when the rotatable hub A is turned to the locked position where the first stop portions 0090 make contact with the second stop portions 0100. In the locked position, the mounting device is secured in the hinge hole.
Referring, for example, to FIGS. 01:01, 02:02-02:05, 03:03, 04:01-04:04, 05:01, 05:02, 06:01, 07:04, 07:05 and 08:01-08:03, rotatable hub A further includes one or more notches 0060 that act as visual cues as to fully locked status during and/or after 90° rotation of part rotatable hub A. Respective ones of the notches 0060 align with respective ones of the notches 0070 on collar part B, which also act as visual cues as to fully locked status during and/or after 90° rotation of rotatable hub A.
Referring, for example, to FIGS. 01:01, 02:05, 03:03, 04:01-04:03, 05:01, 05:02, 06:01, 08:01-08:05 and 09:02, the cover portion E comprises two internal slots 0140 to receive raised tabs 0110 of the collar part B when the mating of the notches 0050 and the tabs 0010 secures the cover portion E to the rotatable hub A. As result, rotatable hub A and collar part B are prevented from unlocking from each other. The two raised tabs 0110 act: (1) as visual alignment guides (tabs parallel to door edge); (2) as installation tool engagement points; and (3) as cover portion E interlocking points. In FIGS. 04:01-04:04 and 05:01-05:04, the mounting device is depicted in the unlocked position(0°) and Part E and O-rings D are not shown. In FIGS. 06:01-06:04, the mounting device is depicted in the unlocked position(0°) and Part E is not shown. In FIGS. 08:01-08:06, rotatable hub A is not shown.
Referring to FIGS. 01:01, 01:02, 03:01, 03:02, 09:01-09:06 and 15:01-15:09, the rotatable hub A and the cover portion E each comprise openings (e.g., holes) 0040 and 0020, which when aligned are configured to receive the support rod C. A support rod sleeve F is formed around part of the support rod C and a latching element 0180 is disposed on top of the cover portion E. The latching element, which is pre-tensioned, includes a latch hook 0190 which engages with a recess 0200 in the support rod sleeve F to secure the support rod C. In an illustrative embodiment, support rod C can be further secured to support rod sleeve F through a “press-fit” type of installation. In FIGS. 09:01-09:06, cover portion E is shown when the mounting device is in a locked position.
Referring to FIGS. 03:05-03:07, the support rod C extends from the mounting device and is configured to connect to a support rack so that a cabinet door to which the mounting device is secured can be supported from the support rack in a cantilevered configuration. More specifically, in FIG. 03:05, the support rack is a drying rack configured to hold multiple cabinet doors, and in FIGS. 3:06-3:07, the support rack is a spray rack configured to hold one cabinet door to be painted. As can be seen in FIGS. 03:05-03:07, the cabinet doors can be supported by two mounting devices and two corresponding support rods C, which are attached between two offset horizontal members of a support rack. The drying rack includes multiple pairs of offset horizontal members mounted on front and rear sides of vertical members, while the spray rack includes one pair of offset horizontal members. The front face of the cabinet doors can face upward or downward (compare FIGS. 03:06 and 03:07) when mounted on the spray rack via the support rods C depending on which side is to be painted. In illustrative embodiments, the support rod C comprises a ¼″×½″×12″ cold rolled steel handle.
Referring to FIGS. 10:01 and 10:02, a mounting device a mounting device used for suspending a cabinet drawer to be painted comprises a hub (Part “AA”), a support rod (Part “CC”); a cover portion (Part “EE”) and a support rod sleeve (Part “FF”). The hub AA comprises one or more internal raised dimples 0030′ to provide for a friction fit when the support rod CC (also referred to herein as a “handle”) is inserted into opening 0040′ (also referred to herein as a “handle slot”). In illustrative embodiments, during manufacturing of the hub AA, material adjacent the opening 0040′ (e.g., pockets of material) is removed to facilitate insertion of support rod CC into opening 0040′ and also save material and/or 3D printing costs. Part FF may be the same as Part F.
Hub AA further includes two notches 0050′ on opposite sides of the hub AA to receive corresponding tabs 0010′ on an inside surface of cover portion EE. The mating (e.g., interlocking) of the notches 0050′ and the tabs 0010′ secures the cover portion EE, which functions as a paint shield, to the hub AA. In order to remove the cover portion EE from the hub AA, the cover portion EE can be squeezed in a horizontal direction to release the tabs 0010′ from the notches 0050′ and lifted vertically off of the hub AA. Horizontal and vertically in this instance assume a particular orientation of the cover portion EE and hub AA. It is to be understood that the orientation may vary, in which case, horizontal and vertical designations may need to be changed to suit a current orientation of the mounting device. The cover portion EE comprises a rectangular opening 0020′, which corresponds to the rectangular opening 0040′ in the hub AA to receive the support rod CC therethrough when the openings 0020′ and 0040′ are aligned. Although depicted as rectangular, the openings 0020′ and 0040′ are not necessarily limited to a rectangular shape, and may comprise a different shape (e.g., square) to accommodate a support rod CC also having a shape other than rectangular.
Referring to FIGS. 11:01 to 11:07, the hub AA (also referred to herein as a “base portion”) is secured to a cabinet drawer via one or more fasteners (e.g., screws). For example, in a non-limiting illustrative embodiment, the one or more fasteners comprise pan head wood screw(s) where the screw length is less than the total depth of hub AA combined with the drawer thickness. The fasteners are driven through holes 0260 (e.g., 4.75 mm diameter holes). In a non-limiting illustrative embodiment, the hub AA, cover portion EE and support rod sleeve FF comprise nylon (PA12) and are 3D SLS printed. Referring to FIGS. 10:02, 11:03, 12:03 and 12:06, the hub AA further include hollowed out portions or voids 0070′ where applicable for material stability, to save material and/or lower printing costs. Referring to FIGS. 10:01, 10:02, 11:03, 12:01, 12:02 and 12:06, the hub AA comprises an offset 0280 to eliminate paint “bridging” between hub AA and the cabinet drawer. In one or more embodiments, the offset is 1 mm high×1.5 mm wide. Referring, for example, to FIGS. 10:01 and 14:03, the cover portion EE comprises tabs 0290 to keep cover portion EE centered and tabs 0010′ interlocked with notches 0050′.
Referring to FIGS. 10:01, 10:02, 11:02, 11:03, 13:01-13:03 and 14:01-14:05, the hub part AA and the cover portion EE each comprise openings (e.g., holes) 0040′ and 0020′, which when aligned are configured to receive the support rod CC. A support rod sleeve FF is formed around part of the support rod CC and a latching element 0180′ is disposed on top of the cover portion EE. The latching element 0180′, which is pre-tensioned, includes a latch hook 0190′ which engages with a recess 0200′ in the support rod sleeve FF to secure the support rod CC. Referring to FIGS. 11:02 and 11:05-11:07, the support rod CC extends from the mounting device and is configured to connect to a support rack so that a cabinet drawer to which the mounting device is secured can be supported from the support rack in a cantilevered configuration. More specifically, in FIG. 11:05, the support rack is a drying rack configured to hold multiple cabinet drawers, and in FIGS. 11:06-11:07, the support rack is a spray rack configured to hold one cabinet drawer to be painted. As can be seen in FIGS. 11:05-11:07, the cabinet drawers can be supported by two mounting devices and two corresponding support rods CC, which are attached between two offset horizontal members of a support rack. The drying rack includes multiple pairs of offset horizontal members mounted one front and rear sides of vertical members, while the spray rack includes one pair of offset horizontal members. The front face of the cabinet drawers can face upward or downward (compare FIGS. 11:06 and 11:07) when mounted on the spray rack via the support rods CC, depending on which side of the drawer is to be painted. In illustrative embodiments, the support rod CC comprises a ¼″×½″×12″ cold rolled steel handle.
In the description above, various materials, dimensions and processing parameters for different elements are provided. Unless otherwise noted, such materials are given by way of example only and embodiments are not limited solely to the specific examples given.
