Heavy duty bracket for multi-level cantilever shelves

Abstract

A wall mounted shelf wherein a diagonal bracket can support an upper shelf, bar or beam several inches above the vertical wall bearing plate. A lower shelf, bar or beam can be hung from the upper shelf. A triangular platform comprises the diagonal bracket, the wall and a top shelf. The diagonal bracket transmits a large force vector into the vertical wall bearing plate as opposed to traditional knee braces that transmit a pivoting vector on the vertical wall bearing plate away from the wall. The result is a cost saving heavy duty shelving system using traditional lumber. An optional variable length diagonal bracket is disclosed. Another embodiment uses the same diagonal pair of brackets to store tires or other objects against the wall and eliminates the shelves and provides a chin up bar. Another embodiment replaces the lower shelf with a chin up bar between two diagonal brackets. Other embodiments include a tire storage mode, a lower bar used for hanging storage which replaces the lower shelf, and a (partially) removed lower shelf for hanging storage such as a bike rack.

DETAILED DESCRIPTION OF THE DRAWINGS

(23) Referring first to FIGS. 1, 2 wall bracket 1 is fabricated with 22 steel angle. They are designed for shelves to be a minimum of 24 deep, but can be deeper. They are designed for shelves, bars or beams to be a minimum of 18 tall, but can be taller. Install the wall brackets then construct the shelving, bars or beams with locally available building products including 24 lumber, plywood, threaded-rod, steel-pipe and associated fasteners and hardware.

(24) A vertical wall mounted bearing plate 2 has a wall mount segment 3 and a 90 degree stiffening segment 4. Holes 5 receive lag bolts 6 which fasten into studs if available. The diagonal strut 7 has a (nominal two inch) vertical segment 8 and (nominal two inch) horizontal segment 9. An L shaped hanger bracket 10 has a vertical segment 11 and a horizontal leg 12 with a hole 13. Welds are labeled W1, W2, W3, W4, W5. Wall mounted segment 3 may have two or three holes 5. Nominal dimensions include D1=27, D2=8, D3=2, D4=24, D5=32, D6=1, D7=3, D8=14, D9=18 minimum, D10=, D11=3. The top support beam (24) is labeled 20, and the optional lower support beam (24) is labeled 21. The outbound support beam (24) 22 is drilled to accept lag screw 231 through hole 24. The upper shelf 25 rests on support beams 20, 22. If the optional lower shelf 26 is added, then a drop rod 27 can be threaded through hole 24 bolted with nut & washer 28, threaded through support beam 22 and lower shelf 26, and threaded through support beam 29, and bolted with nut & washer 30. Lower shelf 26 is supported by lower support beam 21 and drop rod 27 and lower support beam 29.

(25) In FIGS. 3, 4 the shelf assembly 300 has three wall brackets 1 and is dimensioned as shown in FIGS. 2A, 2B. This alternate support for lower shelf 26 uses a second hole 301 for rod 27. A lag screw 23 threads up through hole 13 of horizontal leg 12. The embodiment of FIG. 2A does not require hole 301. In either case the height of the lower shelf below the upper shelf is selected by the user. This is also true for any lower shelves.

(26) In FIG. 5 shelf assembly 300 can support hundreds of pounds of weight. Hooks 555 can screw into lower support beam 21 and support hardware 556.

(27) Referring next to FIGS. 6,7,8A,8B,8C,8D an extendable bracket 600 has a leg B that supports the L shaped hanger bracket 10 that slides on the fixed Leg A that is welded to wall mounted bearing plate 2. Bolts 601 with nuts 602 lock Leg A to Leg B along selected holes A1-A4 in Leg B and holes B1-B4 in Leg B.

(28) Referring next to FIG. 9 the prior art Big Bear (BB) shelf bracket (U.S. Pat. No. 8,864,088) is shown with its shelves in dotted lines overlaid with the shelf bracket 1 shown in FIGS. 1,2 and shown in dotted lines in FIG. 9. The height DH is 7 from the top lag screws on the wall to the bottom of the L shaped hanger bracket 10. The BB height DBB is 5 from the top screw 7 on the wall to the bottom of hanging cutout 953. The 24's 22 and 952 are the same. The present invention has a top shelf fully supported depth of 24 inches versus the BB top shelf of 18 inches. The present invention lower shelf is also fully supported at 24 inches, having a variable height below the top shelf. The BB lower shelf is 9 inch depth and fixed in height down from the upper shelf. It also leaves a gap to the wall behind the lower shelf.

(29) The BB wall cutout 951 supports 24 950 only with a wood screw 950 S.

(30) The BB wall brace BBW has screw holes 958,959. The lower shelf lumber beam 957 is a 26 inch board. The lower shelf cutout for the 26 board is labeled 956. The lower shelf outboard cutout is labeled 954 to secure a standard 24 labeled 955. The fixed height lower shelf 26BB is nine inches deep.

(31) This embodiment eliminates the lag screws 231 of FIG. 2A. Instead the rod 27 passes through a hole 901 in the bottom leg 12 of the L shaped bracket 10 and then through the support beam 22. Nuts 902 secure both ends of the rod 27. Nominal dimensions are:

(64) Referring next to FIGS. 11-14 a multi-mode wall storage systems 1000 and 1600 are disclosed. Module 1004 on FIG. 14 maintains the upper plank 20 and a top shelf 25 and a plank 22 supported by the L brackets 10. The rods 27 support a crossbar 1010. This crossbar 1010 can be used as a hanging storage bar for bike 1011 or a chin up bar. The bike 1011 hangs from the pocket by the handlebar and sprocket 1012 as the handlebars are turned parallel the frame as shown.

(65) Module 1002 eliminates the top shelf to support tires T wedged against the wall W and the crossbar 1010. Not shown are smaller tires that could be stored in space S under shelf 25.

(66) Module 1003 does not need any planks at all. The crossbar 1015 is supported by the L brackets 10.

(67) Not shown could be a continuous two shelf module as shown in FIG. 3.

(68) FIG. 12 shows hole 360 in crossbar 1010. FIG. 13 shows crossbar 1015 having hole 360 with bolt 301 secured by nut 30. FIG. 14 shows the bike 1011 hanging between a wall plank 21 and crossbar 1010. The FIG. 14 system is labeled 1600 with new module 1004.

(69) Although the present invention has been described with reference to the disclosed embodiments, numerous modifications and variations can be made and still the result will come within the scope of the invention. No limitation with respect to the specific embodiments disclosed herein is intended or should be inferred. Each apparatus embodiment described herein has numerous equivalents.
