DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the present invention is a collapsible foldable drying rack 10, which includes opposed scissors frame members 12 and 14, which are connected to each other by a plurality of dowel rods 16.
The scissors frame members 12 and 14 are formed from a plurality of arms, which are connected at their midpoints and their distal ends. More particularly, as shown with frame member 12, first and second arms 28a and 30b are rotatably connected at a midpoint by a connector 34a such as a nut and bolt, as shown, or a rivet or pin. The distal ends 36a and 38a of arms 28a and 30a respectively are then connected to the lower ends 40a and 42a of arms 44a and 46a by connectors 47a and 49a. Arms 44a and 46a are, in turn, rotatably connected at their midpoint by a connector 48a, and rotatably connected to frame members 50a and 52a by connectors 54a and 56a.
Arms 50a and 52a are connected at their midpoint by connector 58a. Arm 52a is connected to a horizontal top arm 60a by a fastener 64a. Arm 60a attaches to the upper end 62a of arm 50a by a fastener 64a.
In this embodiment, the fastener 64a is simply a strap. Other types of removable fasteners or latches can be used. The strap or latch when connected to the upper end 62a of arm 50a holds the frame in an extended position, as shown in FIG. 1.
Likewise, frame member 14 includes first and second arms 28b and 30b, which are rotatably connected by a connector 34b, such as a nut and bolt or rivet shown in FIG. 3. The upper ends 36b and 38b of arms 28b and 30b are then connected to the lower ends 40b and 42b of arms 44b and 46b. Arms 44b and 46b are, in turn, rotatably connected at their midpoint by a connector 48b shown in FIG. 3 and rotatably connected to arms 50b and 52b.
Finally, the arms 50b and 52b are connected at their midpoint by a connector 58b also shown in FIG. 3. Arms 52b is connected to a horizontal top arm 60b by connector 61b. Arm 60b attaches to the upper end 62b of arm 50b. As shown, this connection is made with a strap or latch 64b, which attaches to the upper end 62b of arm 50b.
Opposite ends of the dowel rods 16 are attached to the scissors frame 12 and 14 by three separate sized brackets, a large bracket 70, a medium bracket 72, and a small bracket 74. As shown in FIG. 8, the brackets 70, 72 and 74 have a generally rectangular frame 76 with holes 78 adapted to allow a pin not shown to pass through and attach a dowel rod (or square rod if desired) 16 to the bracket and permit the rod to rotate into an open portion 80 of the respective bracket. The brackets can be any shape as long as they allow the rod to rotate. The brackets are simply attached to the scissors frame with one of the fasteners that hold the arms of the scissor frame member together. As shown, the screw extends through hole 84 and through overlapping arms. In order to keep the bracket from rotating itself relative to the frame, the surface of the arm includes a small hole not shown. A boss 86 in the back side 88 of the brackets 70-74 locate in the hole. The fastener, in combination with the boss, prevents the brackets from rotating. This can also be accomplished using an extra pin or by counter sinking the bracket into the arm.
As can be seen, the brackets 70, 72, and 74 are located on inside surfaces 90 and 92 of arms 30a, 44a, and 52a of frame member 12, and 30b, 44b and 52b on frame member 14. The orientation of the brackets on opposite frame members 12 and 14 is reversed to allow rotation of the dowel rods in opposite directions. Thus, as shown in FIG. 3, the dowel rods attached to frame member 12 rotate in the direction of arrows 94, and the dowel rods in right frame member 14 rotate in the direction of arrows 96.
As can be seen in FIG. 3, the large brackets 70 have a length 98 equal to the length of the medium-sized brackets 72, plus at least the diameter of the dowel rod. Likewise, the medium-sized brackets 72 have a length equal to the length of the small bracket 74, plus at least the diameter of the dowel rod, so that when the frame members 12 and 14 fold over, as shown in FIG. 4, adjacent dowel rods will rest on each other. Thus, the length of the brackets prevents interference of the adjacent dowel rods as the rack is folded.
As shown in FIGS. 1 and 3, the brackets 70, 72 and 74 on frame 12 are complementary to the brackets on the opposite frame 14. In other words, if a large bracket 70 is used on one end of a dowel, the small bracket 74 will be used on the opposite end of that dowel. If a medium-sized bracket 72 is used on one end of a dowel, a medium-sized bracket 72 will also be used on the opposite end of the dowel. Thus, the total length of each of the dowels and their attached brackets is the same.
Dowel 100 extends between horizontal arms 60a and 60b and dowel 102 extends between arms 50a and 50b. In order to provide the required length, spacers 104 equal to the width of one frame member are fixed between the frame member 50a, 50b, and 60a, 60b and the respective bracket. This is required because all of the other dowels attach to inner arms of frame members 12 and 14, whereas the dowel rods 100 and 102 attach to the outer arms of frame members. Alternately larger brackets can be used in place of the brackets and spacer.
Thus, rack 10 folds in two directions. It will collapse downwardly as shown by arrow 110, and will fold 90 degrees as shown by arrows 94 and 96, into the structure shown in FIG. 4. To assemble the device, one simple unfolds the frame member in the direction opposite arrows 94 and 96 to provide the structure shown in FIG. 2. This is then lifted up and straps 64a and 64b are positioned over the ends 62a and 62b of frame members 50a and 50b, holding the structure in position.
Thus, the present invention provides a rack which both collapses and folds, reducing its overall size, reducing shipping space using less display space at a store and less storage space at home.
This has been a description of the present invention along with the preferred method of practicing the present invention. However, the invention itself should only be defined by the appended claims WHEREIN WE CLAIM:
