DETAILED DESCRIPTION
An adjustable bracket or graphic holder is for use in mounting a graphic panel to a top of a display unit. Often, in a retail store, display units, such as gondola display units, are positioned adjacent to each other to form an aisle. Because the floor on which the display units is supported may be uneven and/or tops of the display units may be uneven relative to each other, mounting graphic panels across multiple display units can make the graphic panels appear crooked or out of alignment. The adjustable bracket or graphic holder described in detail below provides a base having an upper flange for coupling to a back side of a graphic panel and a lower flange having an opening. A hardware assembly or fastener located within the opening in the lower flange includes a magnet that is magnetically coupled to the top of a gondola display unit. The hardware assembly or fastener is rotatable within the opening in the lower flange to adjust a height of the graphic panel relative to the floor on which the display unit is supported.
FIG. 1 is a perspective view of an adjustable bracket or graphic holder 100. FIG. 2 is an exploded perspective view of adjustable bracket or graphic panel holder 100. The front, the back, the right side (the left side being a mirror image), the top and the bottom of assembled adjustable bracket or graphic panel holder 100 are illustrated in FIGS. 3-7. Adjustable bracket or graphic holder 100 includes a hardware assembly or fastener 108 and a base or main body 102 having an upper support portion or upper flange 104 and a lower support portion or lower flange 106. Upper support portion or upper flange 104 is configured to be mounted to a graphic or graphic panel, such as graphic or graphic panel 160 illustrated in FIGS. 9-15. As illustrated in FIGS. 1-7 coupled to lower support portion or lower flange 106 is hardware assembly or fastener 108.
Upper flange 104 includes opposing side edges 110 and 112 and an upper edge 114. Lower flange 106 includes opposing side edges 116 and 118 and a front edge 120. Upper flange 104 and lower flange 106 are coupled together by a bend 122 and are oriented substantially normal to each other. In addition, not only are side edges 110, 112, 116 and 118 substantially perpendicular to bend 122, side edge 110 of upper flange 104 is in linear alignment with side edge 116 of lower flange 106 and side edge 112 of upper flange 104 is in linear alignment with side edge 118 of lower flange 106. In addition, upper edge 114 of upper flange 104 is substantially parallel with front edge 120 of lower flange 106.
As illustrated in more detail in the exploded perspective view of FIG. 2, lower flange 106 includes an aperture or opening 124 that extends from a top surface 105 to a bottom surface 107. Aperture or opening 124 is located substantially in the center of lower flange 106. In other words, the center of opening 124 is located at a midpoint relative to front edge 120 and located at a midpoint relative to side edges 116 and 118. Base or main body 102 further includes a nut 140 illustrated in FIGS. 2-5. Nut 140 is fixedly secured to bottom surface 107 of lower flange 106 and includes a threaded hole 141 (shown in FIG. 2) that aligns with aperture or opening 124 in lower flange 106. Nut 140 provides aperture or opening 124 with a threaded interior.
Fastener 108 includes a rod or stud 126, a magnetic foot 128 and a handle 134. In one embodiment and as illustrated in FIG. 8, rod or stud 126 is bored and includes a threaded exterior 130, a threaded interior 132, a first end or a proximal end 136 and a second end or distal end 138. Handle 134 is fixedly attached to first end or proximal end 136 of rod 126. As illustrated in FIG. 7, magnetic foot 128 includes a housing 142 and a magnet 144. Housing 142 surrounds and is attached to a portion of magnet 144 so that only one side of magnet 144 is exposed to the environment. Magnet 144 is capable of producing a permanent magnetic field. For example, magnet 144 can be formed of a ferromagnetic or ferromagnetic material that retains its own magnetization and can respond to other magnetic fields. In general, a permanent magnet is made of some type of metallic material that work is applied to in order to magnetize it. Further, housing 142 and magnet 144 include holes (hidden from view) that align with each other and received a threaded screw 146 as illustrated in FIGS. 2 and 7.
As illustrated in FIGS. 1-7, bored rod or stud 126 is located within aperture or opening 124 of lower flange 106 and threaded exterior 130 of bored rod or stud 126 rotatably mates with aperture or opening 124 using threaded hole 141 of nut 140. Threaded interior 132 of bored rod or stud 126 fixedly mates with magnetic foot 128 using threaded screw 146. As such and as illustrated in FIGS. 1 and 2-7, handle 134 is located above lower flange 106, rod or stud 126 rides in or is rotatable within threaded hole 141 of nut 140 and distal end 138 of rod or stud 126 abuts a top surface 143 of housing 142 of magnetic foot 128. Housing 142 and therefore magnetic foot 128 and magnet 144 are located below lower flange 106 and below nut 140.
Because magnetic foot 128 is fixedly attached to threaded interior 132 of bored rod or stud 126 and because handle 134 is fixedly attached to proximal end 136 of rod or stud 126, magnetic foot 128 including housing 142 and magnet 144 as well as handle 134 are all simultaneously rotatable within aperture or opening 124 and threaded hole 141 of nut 140. Therefore, when handle 134, rod or stud 126 and magnetic foot 128 are rotated within opening 124 and threaded hole 141 of nut 140, a relative distance between magnetic foot 128 and base 102 is adjustable. For example, when handle 134 is rotated in a clockwise direction 133 (FIG. 6), a distance 146 (FIGS. 3 and 5) between bottom surface 107 of lower flange 106 and top surface 143 of magnetic foot 128 increases to thereby adjust graphic or graphic panel 160 (to which upper flange 104 is mounted) upwardly. In another example, when handle 134 is rotated in a counterclockwise direction 135 (FIG. 6), distance 146 between bottom surface 107 of lower flange 106 and top surface 143 of magnetic foot 128 decreases to thereby adjust graphic or graphic panel 160 (to which upper flange 104 is mounted) downwardly.
Furthermore, upper flange 104 of base 102 includes a pair of upper ears 148a and 148b and a pair of lower ears 150a and 150b. The pair of upper ears 148a and 148b are spaced apart from the pair of lower ears 150a and 150b. Upper ear 148a extends outwardly from side edge 110 of upper flange 104 a distance 149a (FIG. 3) and upper ear 148b extends outwardly from side edge 112 of upper flange 104 a distance 149b (FIG. 3). Lower ear 150a extends outwardly from side edge 110 of upper flange 104 a distance 151a (FIG. 3) and lower ear 150b extends outwardly from side edge 112 of upper flange 104 a distance 151b (FIG. 3). Distances 149a and 149b are substantially identical and distance 151a and 151b are substantially identical. In addition, distances 151a and 151b are greater than or larger than distances 149a and 149b. 
FIG. 9 is a perspective view of adjustable bracket or graphic holder 100 being mounted to a back side 162 of a portion of a graphic or graphic panel 160. Mounted to back side 162 of graphic or graphic panel 160 are a pair of channel members 164a and 164b. Together channel members 164a and 164b form a channel 166 for receiving upper flange 104 of main body 102 of adjustable bracket or graphic holder 100. In particular, upper flange 104 is inserted into channel 166 by sliding upper flange 104 in a direction 167 such that channel member 164a engages side edge 110 of upper flange 104 and channel member 164b engages side edge 112 of upper flange 104.
FIG. 10 illustrates multiple of adjustable bracket or graphic holder 100 being coupled to back side 162 of graphic or graphic panel 160. As illustrated, graphic or graphic holder 160 includes a top edge 168, a bottom edge 169 and a pair of opposing side edges 170 and 171. A plurality of substantially identical adjustable brackets or graphic holders 100, 100′ and 100′′ are each inserted into one of a plurality of spaced apart and substantially identical channels 166, 166′ and 166′′. Channel 166 includes channel members 164a and 164b, channel 166′ includes channel members 164a′ and 164b′ and channel 166′′ includes channel members 164a′′ and 164b′′. As illustrated, each upper flange 104, 104′ and 104′′ of each substantially identical adjustable bracket 100, 100′ and 100′′ is inserted into a corresponding channel 166, 166′ and 166′′ by sliding upper flange 104, 104′ and 104′′ in a direction 167, 167′ and 167′′ such that each channel member 164a, 164a′ and 164a′′engages a side edge, such as side edge 110 and side edge 110′ (the corresponding side edge on upper flange 104′′ is hidden from view) and each channel member 164b, 164b′ and 164b′′ engages an opposing side edge, such as side edge 112 and side edge 112′ (the corresponding side edge on upper flange 104′′ is hidden from view). After each upper flange 104, 104′ and 104′′ is inserted and received by each channel 166, 166′ and 166′′, upper ears, such as upper ears 148a′, 148b′, 148a′′ and 148b′′ (the corresponding upper ears on upper flange 104 are hidden from view) as well as lower ears, such as lower ears 150a, 150b, 150a′, 150b′, 150a′′ and 150b′′prevent each substantially identical adjustable bracket 100, 100′ and 100′′ from sliding out of its corresponding channel 166, 166′ and 166′′.
FIG. 11 illustrates a front view and therefore a front side 163 of graphic or graphic panel 160 being mounted to a display unit 202 according to one embodiment. As illustrated in FIGS. 11 and 10, graphic panel 160 extends across the entire width of display unit 202.
In one embodiment, together graphic panel 160 and the plurality of adjustable brackets 100, 100′ and 100′′ provide a graphic panel assembly 300. FIG. 12 illustrates another graphic panel 160′ being mounted to a display unit 204 using multiple of the adjustable bracket described above. Display unit 204 is located adjacent a side of display unit 202. Together graphic panels 160 and 160′ and the multiple of the adjustable bracket 100 mounted to graphic panels 160 and 160′ provide a graphic panel assembly 400. FIG. 13 is a front view of yet another graphic panel 160′′ mounted to a display unit 206 using multiple the adjustable bracket 100 described above. Display unit 206 is located adjacent an opposite side of display unit 202 from display unit 204. Together, graphic panels 160, 160′ and 160′′ and the multiple of adjustable bracket 100 mounted to graphic panels 160, 160′ and 160′′ provide graphic panel assembly 500.
When properly assembled and as illustrated in FIG. 13, graphic panels 160, 160′ and 160′′ all should have substantially identical heights 172, 172′ and 172′′ relative to a floor on which display units 202, 204 and 206 are supported. However, each of graphic panels 160, 160′ and 160′′ can include different widths 174, 174′ and 174′′. In particular, the widths 174, 174′ and 174′′ of each graphic panel 160, 160′ and 160′′ correspond with a width of the display unit to which the graphic panel is mounted. In addition, when properly assembled, top edges 168, 168′ and 168′′ should all be in alignment with each other and bottom edges 169, 169′ and 169′′ should all be in alignment with each other. Because display units 202, 204 and 206 are supported by what may be uneven floor and/or tops of the gondola display units 202, 204 and 206 may themselves be uneven, mounting graphic panels across multiple gondola display units can make the graphic panels appear crooked or out of alignment. To align top edges 168, 168′ and 168′′ and bottom edges 169, 169′ and 169′′, each of the plurality of adjustable brackets or graphic holders 100 that are mounted to and supporting graphic panels 160, 160′ and 160′′ need to be adjusted so as to achieve graphic panel uniformity.
FIG. 14 illustrates a top view of a portion of graphic panel assembly 400 including a portion of graphic panels 160 and 160′, a portion of display units 202 and 204 and a plurality of adjustable brackets or graphic holders 100′ and 100′ for retaining and positioning graphic panels 160 and 160′ on top of gondola display units 202 and 204. Although adjustable bracket 100′ was previously illustrated in FIG. 10 as being inserted into and received by channel 160′ and is substantially identical to the adjustable bracket 100 described above, adjustable bracket 100′′′ was not previously illustrated. However, it should be understood that adjustable bracket 100′′′ is also substantially identical to adjustable bracket 100 described above.
FIG. 15 is a section view taken through the line indicated in FIG. 13. As illustrated in FIG. 15, each magnetic foot 128 and therefore magnet 144 of each adjustable bracket is magnetically coupled to a top rail 208 of each display unit, including display unit 202. Therefore, the magnets in the plurality of adjustable brackets of graphic panel assembly 500 are magnetically coupled to tops of the plurality of adjacent gondola display units 202, 204 and 206.
To adjust the height 172, 172′ and 172′′ of each graphic panel 160, 160′ and 160′′ across its width 174, 174′ and 174′′ to thereby align top edges 168, 168′ and 168′′ as well as align bottom edges 169, 169′ and 169′′, fasteners 108 of each adjustable bracket 100 are rotated to increase or decrease the relative distance 146 (FIG. 3) between bottom surface 107 of lower flange 106 and top surface 143 of magnetic housing 128. By rotating handle 134 of each fastener 108 in a clockwise direction 133 (FIG. 6), the adjustable bracket 100 effectively raises a portion of the top edge and a portion of the bottom edge of the graphic panel that is directly above and directly below where adjustable bracket 100 is mounted. By rotating handle 134 of each fastener 108 in a counterclockwise direction 135 (FIG. 6), the adjustable bracket 100 effectively lowers a portion of the top edge and a portion of the bottom edge of the graphic that is directly above and directly below where adjustable bracket 100 is mounted.
A method of adjusting height 172 of graphic panel 160 includes inserting upper flange 104 of a main body 102 of adjustable bracket 100 into a channel 166 that is coupled to a back side 162 of graphic panel 160. Adjustable bracket 100 is magnetically coupled to a top of a top rail 208 of display unit 202. Handle 334 of fastener 108 that is located in aperture or opening 124 of lower flange 106 is rotated in one of a clockwise direction 133 or a counterclockwise direction 135 to adjust height 174 of graphic panel 160. Height 174 is a height of top edge 168 of graphic panel 160 relative to a floor on which display unit 202 is supported.
