1. Field of the Invention
The invention relates to structural components of household products, and in particular to structural components made from metal for providing strength to the products without adding bulk to the products and/or for providing an improved aesthetic appearance to the products.
2. Description of the Prior Art
There are countless household products such as those used in a kitchen, a bathroom or elsewhere in living quarters, which are made using structural components. The products vary from supporting devices such as hooks or other devices from which objects are hung or otherwise suspended, containers and other storage devices, devices for holding cleaning implements and kitchen utensils, various types of paper holders, bathroom implements of all sorts, mechanical office devices, kitchen devices of all types, etc. It is important that these devices are consistently strong, that they do not sway, that they remain stable when in use and enable objects with which they are used to remain stable, and that the devices are generally easily mobile and not so heavy as to preclude easy movement of the devices, and it is also desirable that the products are aesthetic. Many of the products are partly or entirely formed of metal rods or wires which are usually cylinders that are circular in cross section. Many of these products have stems, hooks, rims, reinforcing bands and the like, and these are often cylindrical or made of sheet metal.
This situation was addressed in U.S. patent application Ser. No. 12/006,835 filed Jan. 7, 2008, which is incorporated herein by reference. The present invention addresses the same issues.
SUMMARY OF THE INVENTIONAn important object of the invention is to provide structural components such as rods or wires which are neither cylinders nor parallelepipeds (and lack throughout their length circular or rectangular cross-sections, respectively), and have aesthetic shapes while providing strength to the products in which they are incorporated.
An object of the present invention is to provide an improved, strong and aesthetically appearing structural component for household products.
Another object is to provide an improved, elongated structural component for household products which are sturdy, aesthetic in appearance and have a discontinuous cross section. (As used herein, a discontinuous cross section of an elongated product means a cross section taken at right angles to the longitudinal axis of the elongated product, the outline or perimeter cross section being composed of at least one of the following characteristics: a combination of at least one curve and at least one straight line; a combination of straight lines which do not form a convex polygon (all of the interior angles are less than 180°, so all of the vertices point “outwardly” away from the center); a combination of curves with at least one of the curves curving in a different direction from at least one of the other curve or curves; or a combination of at least two curves which meet at at least one corner, i.e., at least one generally sharply curved intersection.)
It is an object of the present invention to provide utilitarian products having structural components, and in particular utilitarian products having structural components which provide strength and stability to the products while having an aesthetic appearance.
Another object of the present invention is to provide household products made of structural components which are described above, and which products are strong, stable and not so heavy or bulky by reason of the structural components as to preclude easy mobility of the products, and which are aesthetic in appearance.
It is still a further object of the present invention to provide a utilitarian product at least partially made from metal components which is strong, stable and attractive.
Still a further object is the provision of a household product made of components rendering the product sturdy, stable and mobile, and which can be produced using economical methods of manufacture.
These and other objects will become apparent from the description of the preferred embodiments of the invention to follow and from the appended claims.
The foregoing objects are achieved according to a preferred embodiment of the invention by the provision of an elongated structural component having a discontinuous cross section, and household products made with such a structural component. According to one preferred embodiment, the structural component has an elongated structural component including three curved sections merging at sharp corners. It is composed of a flattened, multi-curved (along its longitudinal axis) metal rod or wire showing in cross section (or having a profile) of two curvilinear end portions on opposite sides of a curvilinear central portion. (The term “rod or wire” as used herein relates to the size of the structural component—a rod design is of a larger size than a wire, although the invention is not restricted by size. The terms “wire” and “rod” may be used interchangeably.) The end portions have opposing, oppositely-curved walls connected respectively by one of a pair of oppositely-curved end walls. The oppositely-curved walls are connected by a generally curved end wall to form part of an oval in cross section, and each of said end-positioned ovals is on opposite sides of the curvilinear central portion. The curvilinear central portion has oppositely-curved sections; the oppositely-curved sections merge with the oppositely-curved sections of the end portions to give the appearance of three merged ovals intersecting at sharp corners, the curved sections having linearly-spaced axes connected by a major axial line, and a uniform minor diameter perpendicular to the major axial line. The merged ovals make the multi-curved metal rod flattened (the major axis is longer than the minor diameter). The multi-curved rod or wire has opposing relatively wide surfaces perpendicular to the minor diameter and the respectively curved end walls form relatively narrow surfaces. The invention includes household products incorporating the foregoing flattened, multi-curved metal rod or wire.
Other preferred embodiments are metal rods or wires having other profiles or cross sections and the household products that include these rods or wires. In another embodiment, a rod or wire is provided which is similar to the foregoing rod or wire, but essentially cut in half so that one surface in cross section is flat and the other surfaces in cross section are end portions which are parts of half ovals (or circles) merged into the opposite ends of a half of an oval. Another embodiment is a structural component whose cross section is in essence a pair of compressed ovals merged on the ends of a larger oval. The major axes of the compressed oval are perpendicular to the major axis of the central, larger oval. In the latter embodiment, the rod or wire is symmetrical about the perpendicular planes including the respective axes. Another embodiment is similar to the preceding embodiment, where the length-to-width ratio is increased. An embodiment similar to the preceding embodiments but having a higher length-to-width ratio is disclosed. An additional embodiment has a cross section similar to a figure eight, where the narrowest portions come close to each other, but do not intersect. There is another embodiment having a symmetrical cross section about perpendicular planes, which is composed of some regular and some irregular curves which merge together at curved intersections. Another one of the preferred embodiments is a rod or wire having a cross section having relatively long, opposing concave portions which are symmetrical about one axis, and relatively short, opposing convex portions connecting concave portions, which are symmetrical about an axis perpendicular to the foregoing one axis. In another embodiment, the cross section has flat side surfaces which are inclined from a position relatively close to the longitudinal axis to opposing regions relatively far from the axis. In the latter embodiment, there is symmetry about perpendicular planes extending through the respective axes. There is a similar embodiment where, in cross section, opposing straight side portions extend from a plane relatively far from an imaginary plane bisecting opposite flat ends of the rod or wire to a position closer to the imaginary plane, and then outwardly to the respective flat ends. According to another preferred embodiment, in its cross section, flat lines are inclined from opposing positions at the center of the rod or wire relatively far from the plane symmetrically dividing the rod or wire, to an opposing position relatively close to the foregoing plane, from which the respective lines are inclined to positions away from the plane to opposing end portions defined by flat lines. There is another preferred embodiment having opposing crenellated lines with intermittent opposing merlons. There is also another preferred embodiment where in cross section the rod or wire has the appearance of opposing sine waves. Still another preferred embodiment has a cross section with merged circles having longitudinal axes in a common plane. Another preferred embodiment which in essence is half if the embodiments discussed above, having in cross section opposing flattened ovals on opposite ends of an oval, where the respective major axes of the end portions are perpendicular to the major axis of the middle oval, except that in the present embodiment the back of the halves is flat. A further preferred embodiment is a rod or wire with a cross section in the nature of the letter “Y.”
The invention may take physical form in certain parts and arrangement of parts, the preferred embodiment of which will be described in detail in the specification and illustrated in the accompanying drawings which form a part hereof, and wherein:
The invention in its preferred form comprises a rod or wire, and implements made in whole or in part of the rod or wire, where the rod or wire has in cross section various perimeters or outlines which are discontinuous. These perimeters or outlines are created by different surfaces on the rod or wire. The perimeters are not circumferences (so the rod or wire is not cylindrical), nor rectangles nor squares (so the rod or wire is not a parallelepiped). The perimeters can consist only of a plurality of curves with at least two of the curves going in different directions than the rest of the curves, curves and straight lines or only straight lines with at least some of the straight lines going in different directions. The cross sections of the rods or wires according to the invention having the foregoing characteristics are referred to herein as “discontinuous cross sections.” The various implements discussed herein that incorporate the rods or wires with the discontinuous cross sections are generally kitchen and bathroom items. None of the intersections of different types of surfaces are sharp intersections having corners defined by lines, but rather are at least slightly curved to avoid stress concentrations and sharp edges at the respective intersections.
Longitudinal axes 26, 28 and 30 lie in the same imaginary plane 38, and as shown in
Rod or wire 10 is symmetrical about imaginary plane 38. Imaginary plane 38 extends through axis 30 about a plane 40 perpendicular to plane 38 which includes axes 26, 28 and 30.
Multi-curved rod or wire 10 has a number of advantageous features. It can be manufactured using conventional extruding equipment with appropriately designed and manufactured dies. Rod or wire 10 is particularly strong, resisting bending by forces applied in the imaginary plane incorporating the parallel longitudinal axes of portions 12, 14 and 16. Rod or wire 10 can be bent using conventional metal bending equipment by forces applied transversely to the foregoing imaginary plane to many different configurations, and the bent rod is stiff enough to maintain those configurations—particularly if it is a tough metal such as stainless steel. Rod or wire 10, whether bent or unbent, can be bonded with other material in making desired products. If rod or wire 10 is made from stainless steel, it can be welded to other steel components to fabricate a desired product.
Rod or wire 10 has an aesthetic appearance. Its flattened, gently curved exterior provides a pleasing appearance having symmetry and suggesting strength. The curves on rod or wire 10 yield an aesthetically pleasing appearance when rod or wire 10 is straight or bent, and further provides an attractive appearance when used with other metallic or non-metallic pieces.
Various items incorporating a multi-curved flattened rod or wire made from metal are discussed below. Also as explained later, there are alternative rods or wires that are part of the present invention. These are various forms of housewares which are strong in use, effective in function and aesthetic in appearance.

Vertical support member 180 is a unitary piece made from rod or wire 10, having vertically-oriented, parallel stems 182 which are connected at their uppermost part by a curved connecting portion 184. The bottom of each stem 182 is an end piece 186 in the form of a “J,” which is attached respectively to support members 178 by an appropriate means, such as MIG welding. The bends of the various parts of vertical support member 180 are in a direction transverse to imaginary planes incorporating the axes of portions 12, 14 and 16 of rod 10 from which vertical support member 180 was made. The free ends of the “J”-shape portions 186 are attached by such means as MIG welding to support members 178 in order to hold vertical support member 180 in a vertical position. A set of branches 188 are disposed between each of stems 182 to which they are attached by an appropriate means, such as MIG welding. Each branch 188 is bowed slightly upwardly, having an upwardly bent main portion 190. The opposite free ends 192 of each of branches 188 are curved upwardly to form a gentle hook. Branches 188 are also made from rods 10 bent as described, with the flattened portions facing generally vertically as shown.
One or more mugs are hung by their respective handles which receive one of branches 188. It can be seen that a handle of each mug is slid over an end 192 of a branch 188 to hold mug M stationary and in place.
Utensil rest portion 210 interconnects sides 204 and is integral with the respective sides 204, and forms a resting location for the utensils. It can be seen that component 210 is twisted in several directions so that portions 12 and 14 are generally vertically disposed with respect to each other to provide a flat surface against which utensils can rest.
A circular wire ring 218, in the geometric form of a torus, is attached by an appropriate means, such as MIG welding, to the inside surfaces of sides 204 in a horizontal position when holder 200 is located on the horizontal ground base. A leg 219, also made from rod or wire 10, is attached such as by MIG welding to wire ring 218, and it has a foot 220 bent from the generally straight portion thereof, to which sphere 208 is attached such as by welding. An appropriate dish or bowl 221 having a rim 222 large enough to overhang ring 218 to suspend dish or bowl 221 from ring 218 is provided. Dish or bowl 221 can easily be removed from ring 218 so that it can be washed or otherwise cleansed. Dish or bowl 221 is preferably made from glass or an appropriately hard plastic.

Ring 232 is made from rod or wire 10 and has been bent by an angle of an appropriate amount, such as 25 interior degrees from the vertical, to provide a circular, resting edge for fruit bowl 230. The circular edge is defined by portion 12 of rod or wire 10 as shown. Upper ring 234 can either be horizontal so that the imaginary axis incorporating the axes of portions 12, 14 and 16 of rod or wire 10 is generally parallel to the horizontal ground or can be tilted to provide an imaginary flow surface into bowl 230.
Fruit bowl 230, like the other embodiments described herein, is preferably made from stainless steel plated with polished chrome. Of course, many other platings are possible.
A round utensil holder 250 is shown in
Attached to the underside of lower ring 252 is a set of three equiangularly placed spheres 260 which serve as support legs or feet for holder 250. Three spherical feet 260 are shown since these provide a stable support for holder 250. A mesh base 262, horizontal to the ground surface when the holder is resting on the ground surface, is attached along its periphery to the inner surface of ring 252. Mesh base 262 could be MIG welded to the inner surface of tower ring 252 or could sit on a circular shelf defined by an inwardly extending bent out shoulder of lower ring 252.
Utensil holder 250 is aesthetic, sturdy and easy to use. Utensils U are stood on base 262 and lean against rings 254 and 258.
Attached to unitary piece 272 is a stand 284. Stand 284 includes a pair of parallel legs 286, connected by an integral crosspiece 288 via a pair of corner portions 289. Legs 286 are attached, such as by MIG welding, to the rearward surface of unitary piece 272. Stand 284 is a unitary member and the forwardly facing flat surfaces face the rearward flat surfaces of unitary piece 272. Whereas the flat surfaces of feet 278 engage the ground surface, portion 12 of rod 10 of which stand 284 is made engages the ground. Each component of cookbook holder 270 is made from rod or wire 10, each component being bent as shown to provide a stable and attractive support for a cookbook.

Section 382 is bent far enough back from the longitudinal axis of circular base 372 to enable the stable hanging of a bunch of bananas B to be suspended from hook 390 without engaging banana support 380. Furthermore, section 382 is so curved as to render it stable whether or not a bunch of bananas is hung on it. This is because the center of gravity is within base 372.
Other than feet 374 and hook assembly 387, banana hanger 370 is made entirely from rod or wire 10. Banana hanger 370 is strong and sturdy in both function and appearance, and pleasing to observe. It can be fabricated using conventional manufacturing processes and techniques.
A suction basket 420 according to the invention is shown in
A suction cup-receiving member 446 for each suction cup comprises a cylindrical wire formed into a rectangular shape having a neck-receiving orifice therein and is welded to each of a pair of legs 432. Protrusion 444 of each of a pair of suction cups 442 is inserted through respective orifices 447 in each of members 446 to attach suction cups 442 to the remainder of suction basket 420.
The foregoing embodiments of the present invention each comprise a flattened multi-curved rod 10 composed basically of a pair of elliptic cylinders merged into opposite curved end portions of a larger elliptic cylinder, with their respective longitudinal axes being in a common plane. There are other rods or wires having different cross-sectional shapes, more particularly having other discontinuous cross sections, which are described below, and which could be used with the various products shown in
Referring to
As indicated earlier, rod or wire 510 is usually secured to a utilitarian product of which it forms a part, and if rod or wire 510 is either steel or chrome-plated steel attached to a metal member, MIG welding is oftentimes a good procedure for attaching rod or wire 510 to the utilitarian product. Rod or wire 510 is both strong and attractive in appearance. As was true with rod or wire 10 discussed above, rod or wire 510 is strong, able to resist bending forces applied transversely to it, and has a strong resistance to bending forces in a plane parallel to the common plane of axes 526, 528 and 530. Rod or wire 510 can have heights in its preferred form on the order of 0.36 inches, 0.625 inches or 0.80 inches, with the height-to-width preferred ration as mentioned earlier. Rod or wire 510 could be used in any of the implements shown in
Another rod or wire 560 is shown in
It should be noted that the various curved portions shown in FIGS. 19 and 19A-19C could be varied somewhat while maintaining the overall configuration of rod 560. This is shown, for example, in rod or wire 590 shown in
Another rod or wire 610 is shown in FIGS. 22 and 22A-22C. These are perspective, cross-sectional, top and side views, respectively. Rod 610 is symmetrical in configuration and has two relatively enlarged end portions 612 and 614 on opposite sides of a narrow portion 616. Rod 610 can be described as having a cross section in the form of a figure “8” but without the opposite sides crossing each other but rather coming close together at narrow portion 616 and then proceeding outwardly toward the opposite end. End portions 612 and 614 are partly cylindrical in nature and give the appearance of having been stretched out apart from the narrow portion 616. Each of the curves in rod 610 is smooth and continuous, and has a graceful appearance. The cross section is discontinuous because the curves go in different directions. End portions 612 and 614 have longitudinal central axes 626 and 628, as does central portion 616 at axis 630, all of which are in a common plane 634 as shown in
The use of rod 610 and the manner of attachment to the utilitarian product are basically the same as those for rods 10, 510, 560, 580 and 590. As shown in
FIGS. 23 and 23A-23C disclose another rod or wire 660 composed of various curved portions. Rod or wire 660 has central axis 662, opposing enlarged portions having respective longitudinal axes 664, 665, and opposing end enlarged portions having longitudinal axes 666, 667, respectively. A plane 668 shown in
Rod or wire 660 has (as shown in
Rod or wire 660 is sturdy and aesthetically pleasing, and can be used in many utilitarian pieces to add strength to them and/or to make the rod or wire 660 more attractive. The cross section has a discontinuous cross section because the curves go in different directions. The cross section of rod or wire 660 can be described as having a central waist 673 which gently bulges outwardly to wide portions 675, from which it gently contracts inwardly to a narrow waist 677, and to wide sections 679 having semi-circles 681 between portions 679.
Another rod or wire 700 is shown in
Rod or wire 700 can be incorporated in many utilitarian household items, adding strength and beauty to them. If made of metal, they can be welded to other metal parts. They can be bent and twisted as can other rods or wires discussed herein.
FIGS. 25 and 25A-C illustrate another rod or wire 730 according to the invention in perspective, cross-sectional, top and side views, which like the rods or wires disclosed herein can be used in various inventive utilitarian products. Rod or wire 730 is composed of various straight portions which converge at round portions. The description as follows considers rod or wire 730 as shown in the figures having top and bottom portions and side portions. Rod or wire 730 has a central longitudinal axis 732, a vertical plane 738 (as rod or wire 730 is oriented in
Referring next to
Rod or wire 760 can be bent or twisted as noted with the other rods or wires discussed herein as inventive embodiments of the invention and can be used with inventive utilitarian products to which they add strength and/or attractiveness. Rod or wire 760 has a discontinuous cross section as a result of the straight lines going in different directions and to the presence of straight lines and curves.
Another embodiment of the wire or rod according to the invention 800 is shown in
Wire or rod 800 has an inclined flat surface 812 which runs between a curved transition surface 814 located relatively far from vertical central axis 806 to a curved surface 816, which is relatively close to vertical curved axis 806. Another flat surface 818 is inclined from curved portion 816 to a curved portion 820 which is relatively far from vertical axis 806 than is curved portion 816. Curved portion 820 serves as a merging surface between inclined flat surface 818 and an inclined flat surface 822, the latter being symmetrical with flat surface 818. Flat surface 822 proceeds to a curved transition portion 824 which is symmetrical with curved portion 816 about horizontal plane 804. An inclined flat surface 826, symmetrical with flat surface 812 extends from curved surface 824 to a curved surface 828 which serves as a transition between flat bottom surface 810 and flat surface 826.
Wire or rod 800 can be seen to be composed of identical symmetrical portions 803 and 805 which are symmetrical about horizontal central plane 804 and vertical central axis 806. The surfaces on the right side of vertical axis 806 are symmetrical with the surface on the right side of vertical plane 806, and are given the same numbers with a prime (“′”) designation. Rod or wire 800 has a discontinuous cross section because it is composed of straight lines going in different directions, and because it is composed of straight lines and curves. Rod or wire 800 has the advantages discussed with respect to the other inventive rods or wires disclosed herein, in that it is strong, can be bent to form many items and is attractive to view.
Another inventive rod or wire 860 is shown in perspective form in

Another embodiment similar to those shown in
The rod or wire 980 is shown on an inventive shower hook 1000 made from rod or wire 980, shown in FIGS. 33 and 33A-33D. As explained above and with particular eference to
Shower hook 1000 is shaped like an “S” as shown in
Shower rod-receiving loop 1004 has a free end portion 1008 which wraps slightly around the space within loop 1004 to help prevent shower hook 1000 from slipping off a shower rod. Arms 982 and 984 have rod-engaging surfaces 996, 998 for engaging a curved curtain rod on opposite sides of the curtain rod to hold the shower hook 1000 stable on the rod. Arm 986 adds rigidity to rod or wire 980 to assist in preventing unwanted bending of hook 1000.
The sizes of different parts of shower hook 1000 can vary for many reasons. Some of the dimensions which are preferred are an overall height H of 3.09 inches, a depth D of 2.24 inches, and an opening O between end portion 1004 and a straight portion 110 extending between shower curtain-receiving part 1002 and shower rod-receiving loop 1004, in the amount of 1.06 inches. Sphere 1006 has a diameter d of 0.50 inches.
Rod or wire 980 is strong, aesthetic and can be used for many products used in many different places, particularly in bathrooms, kitchens and households generally. Rods or wires 980 can be the only components of the products incorporating a rod or wire 980 or can be used with other components made, for example, from plastic, glass, ceramic, metal and natural materials such as different varieties of wood. Rod or wire 980 is very strong when made from steel, which could be finished such as by being chrome plated.
Rod or wire 980 has a discontinuous cross section. Rod or wire 980 in cross section has both curves and straight lines, and the curves go in different directions.
The invention further includes other types of rods or wires used for making many types of products, such as those shown in
Another rod or wire 1050 according to the invention is shown in FIGS. 35 and 35A-35C. Rod or wire 1050 has generally flat or slightly outwardly curved top and bottom surfaces 1052 and 1054, respectively (as shown in the drawings), and opposite, slightly outwardly-curved side surfaces 1056 and 1058. Side surfaces 1056 and 1058 merge with top and bottom surfaces 1052 and 1054, respectively, at curved surfaces 1060, 1062, 1064 and 1068. A series of rows 1070 and 1072 of equally-shaped indentations 1074 and 1076 are disposed on side surface 1056, and a series of rows 1078 and 1080 of indentations 1082 and 1084 on side surface 1058. The respective indentations 1074, 1076, 1082 and 1084 in each of rows 1070 and 1072, 1078 and 1080 are equally shaped, and the respective indentations 1074 and 1076 in the respective rows 1070 and 1072 are in alignment with indentations 1082 and 1084 in rows 1078 and 1080. Indentations 1074, 1076, 1082 and 1084 provide an attractive appearance to rod or wire 1050 and, in some instances, may be useful in providing surfaces for traction to enable grasping of rod or wire 1050 in some instances.
A still further rod or wire 1090 is shown in FIGS. 36 and 36A-36C. Rod or wire 1090 is a medium dimpled, profiled wire having enlarged upper and lower portions 1092 and 1094 (as viewed in the drawings), symmetrically disposed about a central portion 1096. Central portion 1096 has opposing sides 1098 and 1100, and extending along the respective sides 1098 and 1100 are respective rows of equidistant dimples 1101. This configuration renders rod or wire 1090 both useful and attractive. It can be used in the same general manner as have been the other rods or wires discussed in this application.
Turning to FIGS. 37 and 37A-37C, a medium-wide rib profile rod or wire 1110 is shown. Rod or wire 1100 has on one side an enlarged top and bottom portion 1102 and 1104 (as shown in the drawings), respectively, and an intermediate portion 1106 disposed between upper and lower portions 1102 and 1104, respectively. Rod or wire 1110 has a flat back portion 1108. Upper and lower portions 1102 and 1104, respectively, merge into central portion 1106 with curved portions 1109 and 1111. Upper and lower portions 1102 and 1104, respectively, have curved back portions 1114 and 1116 which merge into back portion 1108. A series of outwardly extending ribs 1118 extend along the front portion 1106 and provide both an attractive appearance and a strengthening feature to rod or wire 1110. Ribs 1118 are identical, and their upper portions and lower portions are in alignment with their adjacent side portions touching each other.
