DETAILED DESCRIPTION OF THE INVENTION

(19) According to various embodiments, the present invention provides an adjustable hanger assembly. The assembly includes a slider, a slider base, and a spring. The slider comprises a top end, a bottom end, a front wall extending from the top end to the bottom end, and a back wall extending from the top end to the bottom end. A plurality of teeth, for example, from about ten to about 20, are provided protruding from the back wall toward the front wall. Each of the teeth extends downwardly at an angle and terminates in a distal edge. The teeth are arranged adjacent to one another such that the distal edges of the teeth are parallel to one another. The slider base comprises one or more fasteners for securing the spring. The slider base has a top end, a bottom end, a groove for slidingly engaging the slider, a base front wall at least partially defining the groove, and at least one catch tooth protruding from the base front wall into the groove. The catch tooth is angled upwardly toward the base top end terminating in a distal catch end. The catch tooth forms a catch groove between the distal catch end and the base front wall. The spring is fastened to the slider base by the fasteners. In some embodiments, the slider base can comprise a plurality of catch teeth and the slider can comprise just one tooth or more. The slider, slider base, or both, can be provided with tabs or locking tabs to prevent the slider from being extended too high or too low with respect to the slider base.

(20) In operation, the slider is slidingly engaged in the slider base. The spring is configured to urge the plurality of teeth of the slider into engagement with the at least one catch tooth. The slider is configured to be biased by the spring. The slider is configured to be pushed against the spring to deform the spring, in the groove, and to enable the slider to move up and down in the groove while the plurality of the teeth of the slider are disengaged from the at least one catch tooth. Different teeth of the plurality of teeth can engage the at least one catch tooth and thus the height of the slider can be adjusted with respect to the slider base. Alternative configurations are also within the realm of the present invention and include such differences as having a plurality of catch teeth and only a single tooth on the slider. The relative height, when mounted on a wall, of the slider with respect to the slider base, can therefore be adjusted.

(21) According to various embodiments of the present invention, the slider base can have a back wall and the back wall can have an inner surface and an outer surface. The inner surface can partially define the groove of the slider base. The outer surface can comprise one or more horizontal rails extending therefrom. The adjustable hanger assembly can also comprise a mounting bracket configured to be fixedly secured to a wall and comprising one or more horizontal receiving grooves for receiving the one or more horizontal rails. With such an arrangement, the slider and slider base can be adjusted horizontally, with respect to the mounting bracket. The horizontal rails can have a cross-section and the horizontal receiving grooves can have a corresponding cross-section that is complementary to and configured to receive the horizontal rails. The horizontal rails can have a substantial circular cross-section, an inverted triangular cross-section, an inverted trapezoidal cross-section, or the like. The slider front wall can include a hanger formed on the outer surface. The hanger can be in the form of a post, a pivotable post, a pin, a knob, a hook, a double hook, combinations thereof, or the like.

(22) The hanger can be in the form of an at least partially round protrusion extending from the slider front wall. The round protrusion can have a shoulder, for example, at a distal end thereof. Between the shoulder and the slider front wall a hanger groove can be defined, for example, between the shoulder of the hanger and the front wall of the slider. In some embodiments, the hanger assembly can further comprise a hook plate. The hook plate can comprise an outer surface, an inner surface, a top end, a bottom end, and a hook mounted or otherwise secured or formed as part of the outer surface. The bottom end of the hook plate can include a clip, for example, to engage a recess in the slider. The inner surface of the hook plate can include a recess for accommodating a hanger, if a hanger exists on the slider. The inner surface of the hook plate can include one or more additional recesses, for example, a recess to accommodate a plurality of gripping ridges formed on the outer surface of the slider. In some embodiments, the slider can be flat on a front surface thereof, such that it does not include a hanger, and the inner surface of the hook plate can therefore be flat and need not include a recess for accommodating a hanger.

(23) With reference now to the drawings, FIGS. 1A-7B shows an adjustable hanger assembly 10 according to various embodiments of the present invention. Assembly 10 includes a slider 20, a slider base 22, and a spring 24. Each of the components can comprise a metal material, a plastic material, or the like. Slider 20 includes a top end 26, a bottom end 28, a front wall 30 extending from top end 26 to bottom end 28, a back wall 32 extending from top end 26 to bottom end 28, and a plurality of teeth 34. The number of teeth can be any suitable amount, for example, one tooth, two teeth, three teeth, four teeth, five teeth, or more. The slider can have ten teeth or more. Each of teeth 34 protrudes from back wall 32 toward front wall 30 and extends downwardly at an angle. The angle can be one degree or more, five degrees or more, ten degrees or more, 89 degrees or less, 75 degrees or less, or within any suitable range, for example, from about 15 degrees to about 75 degrees, from about 30 degrees to about 60 degrees, or from about 40 degrees to about 50 degrees. The angle can be about or exactly 45 degrees. Each tooth 34 terminates in a distal edge 36. The plurality of teeth 34 can be arranged adjacent one another such that distal edges 36 are parallel to one another or otherwise have the same or a similar profile or edge shape.

(24) Slider base 22 can include one or more fasteners 40 for securing spring 24 to slider base 22. The fasteners can be or comprise bridges, arches, loops, punch-outs, slots, adhesive pads, a threaded connection, combinations thereof, and the like. Slider base 22 can have a base top end 42, a base bottom end 44, a groove 46 for slidingly engaging slider 20, a base front wall 48 at least partially defining groove 46, and at least one catch tooth 50 protruding from base front wall 48 into groove 46. Catch tooth 50 can be angled upwardly toward base top end 42, terminating in a distal catch end 52 forming a catch groove 54 between distal catch end 52 and base front wall 48. In some embodiments, slider 20 can have one or teeth and slider base 22 can have a plurality of catch teeth. Spring 24 can be fastened to slider base 22 by fasteners 4 as shown in FIG. 5A.

(25) The different components of assembly 10 can be provided together as a kit, for example, disassembled. In use slider 20 is slidingly engaged in groove 46 of slider base 22. Spring 24 is configured to urge the plurality of teeth 34 of slider 20 into engagement with catch tooth 50. Slider 20 can be configured to be biased by spring 24 and spring 24 can be formed of any suitable shape to provide such a biasing effect, for example, spring 24 can comprise a leaf spring. Slider 20 can be configured, along with groove 46, so that slider 20 is urged against spring 24. Spring 24 can thus be slightly deformed, for example, even when one or more of teeth 34 are engaged with catch tooth 50. To adjust the slider position relative to the slider base, the slider can be pushed toward the slider base, against the spring, to disengage the plurality of teeth 34 from catch tooth 50, then while maintaining the disengaged relation, slider 20 can be slid up or down within grove 46 of slider base 22. Once the applied pressure for urging slider 20 toward slider base 22 is released, the plurality of teeth 34 are then biased into engagement with catch tooth 50 and downward movement of slider 20 with respect to the slider base 22 is prevented. When slider base 22 is mounted to a wall, or engaged with a mounting bracket mounted on a wall, the relative height of the adjustable hanger assembly can be vertically adjusted. Vertical adjustment can be made with a single finger or thumb, without the need for tools. The spring only needs to provide very little biasing force as gravity also forces the slider teeth into engagement with the catch teeth. There is little if no need to press the slider in while moving the slide upwardly as a ratcheting effect occurs when slid upwardly and the teeth of the slider are not acting against the catch teeth. The assembly is free of, that is, does not include a structure interfering with up and down translation when the slider is depressed. Within the groove or channel formed in the slider base, the spring provides a floating effect against any structural interference. The spring can be provided separately and then installed in the slider base, or pre-connected to the slider base, for example, inserted into slots, riveted, welded, integrally-molded, or otherwise formed with, or as part of, the slider base. The spring can comprise a metal material, a plastic material, or the like. Other spring types such as coiled springs can be used. Deformable foams and plastics can be used, for example, elastically deformable closed-cell foams.

(26) According to various embodiments, slider base 22 can have a base back wall 56 having an inner surface 58 and an outer surface 60. Inner surface 58 can define or partially define groove 46. Outer surface 60 can comprise one or more horizontal rails 62 extending therefrom. Adjustable hanger assembly 10 can further comprise a mounting bracket 64 configured to be fixedly secured to a wall, for example, by adhesive, pressure sensitive adhesive, double-sided tape, a hook and loop fastener combination, screws, screw and anchor combinations, spiral anchors, bolts, molly bolts, nails, or the like. Mounting bracket 64 can comprise one or more horizontal receiving grooves 66 for receiving horizontal rails 62 of slider base 22. Horizontal receiving grooves 66 can be of a cross-sectional shape configured to accommodate and receive horizontal rails 62, for example, of a complimentary shape. Each of horizontal rails 62 can have the same or different cross-sectional shape as one or more other horizontal rails 62. Each horizontal rail 62 can have an inverted trapezoidal cross-sectional shape as shown in FIGS. 1B-1E and 5B-7B. Other cross-sectional shapes of horizontal rails 62 and horizontal receiving grooves 66 can be used, for example, round cross-sections, inverted triangular cross-sections, and the like.

(27) According to various embodiments, slider front wall 30 can have an outer surface 31 and a hanger 25 formed on outer surface 31. Hanger 25 can be or comprise a hook, a post, a pivotable post, a knob, combinations thereof, and the like. Hanger 25 can be in the form of an at least partially round protrusion extending from the slider front wall and defining a hanger groove 27.

(28) FIG. 2A illustrates a use for adjustable hanger assembly 10 as a hat hanger. FIG. 2B illustrates the use of four adjustable hanger assemblies for hanging four frames, spaced apart, where fine adjustments in both vertical and horizontal directions might be desired.

(29) FIG. 3 shows an embodiment of an adjustable hanger assembly 12 that differs from assembly 10 in that no mounting bracket is used with the assembly. In the embodiment shown in FIG. 3, slider base 22 is mounted directly onto a wall 41, for example, by adhesive, pressure sensitive adhesive, double-sided tape, a hook and loop fastener combination, screws, screw and anchor combinations, spiral anchors, bolts, molly bolts, nails, or the like.

(30) FIG. 4 shows mounting bracket 64, alone, mounted on a wall 41 by two screws 70. The beveled opening of the screw through-holes and beveled nature of the screw heads enable the screws to be set such that they are flush with the facing surface of mounting bracket 64. Horizontal receiving grooves 66 are shown having inverted trapezoidal cross-sections.

(31) FIGS. 5A and 5B show slider base 22 in greater detail. Fasteners 40 are shown in the form of bridges, spring 24 is shown as a leaf spring, and the opposing ends of leaf spring 24 are tucked under the respective bridges to fasten leaf spring 24 to slider base 22. In FIG. 5A mounting bracket 64 has been omitted but mounting bracket 64 is shown in FIG. 5B as is the complimentary, inverted trapezoidal, relationship between horizontal rails 62 and horizontal receiving grooves 66.

(32) FIG. 6 shows slider 20 engaged in slider base 22, in partial cross-section. With reference also to FIG. 1E, slider 20 can be accommodated in, and captured in, groove 46 of slider base 22, with front wall 30 of slider 20 outside of groove 46 and back wall 32 of slider 20 inside groove 46. Back wall 32 of slider 20 can comprise two columns of teeth, one on the left-hand side and the other on the right-hand side. The two columns of teeth can be separated by a solid center 72 that connects back wall 32 to front wall 30 of slider 20. Solid center 72 of slider 20 can slip the front opening of slider base 22, which opens into groove 46. Front wall 48 of slider base 22 comprises left and right portions separated by a gap that is wide enough to accommodate solid center 72 of slider 20. As such, a design such as a carriage captured on a rail is provided, preventing lateral or horizontal movement of the slider with respect to the slider base. Furthermore, a stop feature 33 is provided at the top of slider 20 (FIGS. 1C-1D), in the form of a top wall, to prevent slider 20 from falling through and out of slider base 22. A catch 35 can also be provided at or near bottom end 28 to prevent slider 20 from being slid out of the top of groove 46 and slider base 22.

(33) FIGS. 7A and 7B show how slider base 22 can be moved horizontally with respect to mounting bracket 64 and illustrates how horizontal rails 62 of slider base 22 move within horizontal receiving grooves 66 of mounting bracket 64. One or both of horizontal rails 62 and horizontal receiving grooves 66 can be provided with notches, ridges, bumps, or other features so that a specific horizontal orientation can be achieved and maintained. Such features are shown in the top horizontal receiving groove 66 shown in FIG. 7B; corresponding complimentary features can be provided on the top horizontal rail 62.

(34) A particular advantage of the present invention is the ability of the hanger to be raised to a height that is above the height of the slider base and above the height of the mounting bracket. The slider base, mounting bracket, or both, can have respective top edges, and the top of the slider, including the top of the hanger, can extend above the top surface of the slider base, mounting bracket, or both. With such a feature, no part of the assembly shows behind a frame or behind many an object hung by the assembly. The extension of the hanger above the slider base top edge and above the mounting bracket top edge can be seen at least in FIGS. 1A-1D, 2A-3, and 6-7B.

(35) With reference to FIGS. 8A-8E, adjustable hanger assembly 10 can further comprise a hook plate 80 comprising an outer surface 81, an inner surface 83, a plate top end 85, and a plate bottom end 87. Outer surface 81 can comprise a hook 82. Plate bottom end 87 can comprise a clip 88. Inner surface 83 can comprise a first recess 84 for accommodating hanger 25 of slider 20. In some embodiments, outer surface 31 of slider front wall 30 further comprises one or more horizontally arranged ridges 38 protruding therefrom, for example, to assist in gripping and sliding slider 20, and inner surface 83 of hook plate 80 can comprise a second recess 86 for accommodating horizontally arranged ridges 38. Slider 20 can include a clip notch 90 as shown in FIG. 8E, for example, in plate bottom end 87, to accommodate clip 88 of hook plate 80.

(36) In some embodiments, slider 20 can be free of, that is, not include, a hanger, such as depicted in FIG. 8E. In such embodiments, hook plate inner surface 83 does not need to be provided with an opening, hole, or first recess to accommodate a hanger. As shown in FIG. 8C, however, first recess 84 for accommodating hanger 25 of a slider can include a catch edge 94 for catching the top edge of hanger 25. Together with clip 88 and clip notch 90, catch edge 94 can prevent hook plate 80 from dislodging from slider 20.

(37) FIGS. 9A-9C show another embodiment of a slider 920 that includes a pivotable post 922 that can be pivoted to extend from the front face of slider 920, for example, at an upwardly extending angle. The angle can be any suitable upward angle such as one degree or more, five degrees or more, ten degrees or more, 89 degrees or less, 75 degrees or less, or within any suitable range, for example, from about 15 degrees to about 75 degrees, from about 30 degrees to about 60 degrees, or from about 40 degrees to about 50 degrees. The angle can be about or exactly 45 degrees. Pivotable post 922 can fold into a post recess 924 built into the front wall of slider 920. Pivotable post 922 can pivot about a pivot pin 926 and post recess 924 can be provided with a pivot pin recess (not shown) into which pivot pin 926 can be snapped or otherwise pivotably mounted.

(38) FIGS. 10A and 10B show another embodiment of a base slider 122 that can be screwed or otherwise mounted directly onto a wall. Screws 134 and 136 can be used to mount the base slider to a wall 141. Base slider 122 can be provided with through-holes through the back wall thereof to accommodate screws 134. Either or both of the through-holes and screws can be bevelled to provide a flush mounting. The spring has been removed from base slider 122 for the sake of simplicity, and to reveal a levelling feature 144 (FIG. 10B). Leveling feature 144 can comprise, for example, a level comprising an air bubble captured in a graduated liquid vessel. A hanging plumb line (not shown) can instead be attached to or otherwise provided with or on the slider base so that it can be mounted perfectly straight up-and-down.

(39) FIGS. 11A and 11B are front views of a mounting bracket 264, according to various embodiments of the present invention, that includes yet another leveling feature. Mounting bracket 264 has a recess or opening 284 and a dangling plumb line 280 in the form of a string of beads, such as hollow metal beads. Plumb line 280 can be secured at a top, first bead 282, to the top of recess 284 and can be of such a length as to dangle freely, unobstructed, within recess 284. Plumb line 280 can be lined-up with, i.e., aligned, with a level mark 286 that can comprise an etched groove, cut, indicia, or other marking to show where mounting bracket is vertically aligned.
