Abstract
A decorative twisted spiral garland includes one or more continuous webs of material, each arranged in a series of flattened, generally helical coils about a longitudinal axis, with the coils extending generally transversely of the axis and having a predetermined pitch longitudinally of the axis, and a pair of wires extending generally parallel to the axis outside of the coils and respectively along opposite sides of the coils, the wires being twisted together along the axis so that the coils are pinched together along the axis and twisted about the axis. The actual shape of the garland depends upon the amount of twist imparted to the wires and coils. One or more filaments may also be disposed along the axis inside the coils and twisted together with the wires and the coils.
Description




BACKGROUND OF THE INVENTION




The present invention relates to decorative garlands of the type commonly used for decorating Christmas trees, wreaths, and the like, and which may be suspended from ceilings, attached to walls and used as decorations in connection with other objects and structures.




Prior garlands have been made of a variety of types of materials and in a variety of different shapes and designs. Many such garlands are formed by twisting or rotating together materials which have been preprocessed in a specialized way, such as cutting to predetermined shapes or the like, such preprocessing adding considerably to the expense of the garland. Other garlands, formed of readily available raw materials which have not been preprocessed, have resulted in garlands which either have a tight rope-like design or otherwise present a non-unique appearance.




SUMMARY OF THE INVENTION




It is a general object of the invention to provide an improved decorative garland which avoids the disadvantages of prior garlands, while affording additional structural and operational advantages.




An important feature of the invention is the provision of a decorative garland which can be formed of readily commercially available materials, without any preprocessing of the materials.




Another feature of the invention is the provision of a garland of the type set forth, which is of relatively simple and economical construction.




Another feature of the invention is the provision of a garland of the type set forth, which presents a unique decorative appearance.




In connection with the foregoing feature, a further feature of the invention is the provision of a garland of the type set forth which has a twisted configuration, and which can be formed in a variety of significantly different finished appearances by variation of the amount of twist imparted to the garland.




Certain ones of these and other features of the invention may be attained by providing a decorative garland comprising: a pair of elongated core wires twisted together along a longitudinal axis, and a continuous web of material arranged in a series of consecutive portions extending longitudinally of the web, with each portion inclined with respect to the axis at a predetermined acute angle, each portion having an inner end disposed adjacent to the axis and an outer end spaced radially from the axis, the web being disposed between the wires at each of the inner ends, each web portion having a leading side edge with the leading side edges of alternate portions being spaced apart a predetermined distance along the axis.




Other features of the invention may be attained by providing a decorative garland of the type set forth, wherein the continuous web of material is arranged in a series of consecutive, longitudinal folds, with each fold including a longitudinal reach and a bend, with each reach extending generally transversely of the axis and having a leading side edge, the leading side edges of alternate reaches being spaced apart a predetermined distance along the axis, the web extending between the wires at alternate bends.




Still other features of the invention may be attained by providing a decorative garland of the type set forth, wherein the continuous web of material is arranged in a series of flattened, generally helical coils about the longitudinal axis, with the coils extending generally transversely of the axis and having a predetermined pitch longitudinally of the axis, the wires extending outside of the coils and respectively along opposite sides of the coils, so that the twisting of the wires causes the coils to be pinched together between the wires at the axis and twisted about the axis to form coil halves, such that each coil half is spaced rotationally about the axis at a predetermined angle from adjacent coil halves.




The invention consists of certain novel features and a combination of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the details may be made without departing from the spirit, or sacrificing any of the advantages of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, there is illustrated a decorative spiral garland, generally designated by the numeral


10


, constructed in accordance with a first embodiment of the present invention. The garland


10


may be formed on a machine like that disclosed in copending U.S. application Ser. No. 09/447,038 filed Nov. 19, 1999 filed on even date herewith and entitled “Method and Apparatus for Making Spiral Garland,” the disclosure of which is incorporated herein by reference, but could also be formed by other apparatus or by hand. Referring to

FIG. 2

, there is illustrated a pair of threaded rods


11


and


12


which are rotatable about their axes and form a part of the machine of the aforementioned copending application for forming the garland


10


, illustrated herein to assist in understanding the method by which the garland


10


is formed, thereby to better understand its construction. The garland


10


is made up of a pair of core wires


13


and


14


, a pair of filaments


15


and


16


and two continuous ribbon webs


20


and


30


. Preferably, the webs


20


and


30


respectively have different visually distinguishable characteristics, indicated in the drawings by the stippling of the web


30


, which characteristic could be color, texture, print design, or any of a number of other characteristics. Preferably, the webs


20


and


30


have the same width W.




The rods


11


and


12


form a framework around which the webs


20


and


30


are wound, respectively forming flattened, helical coils


21


and


31


. The rotation and threading of the rods


11


and


12


is such as to advance the coils


21


and


31


to the right, as viewed in

FIG. 2

, new coils being added to the left of the figure. As can be seen, the coils


21


and


31


alternate, each having the same pitch P, which is approximately twice the web width W. In the illustrated embodiment there is a slight spacing between the coils, somewhat exaggerated in

FIG. 2

to facilitate distinguishing the coils, so that the pitch P is slightly greater than 2W. While in the preferred embodiment, the pitch P is not less than 2W, it could be less than 2W, so that the coils overlap each other, or significantly greater than 2W so that adjacent coils are spaced farther apart, but in those cases the appearance of the finished garland would be different.




To assist in understanding the construction of the garland


10


, a single “coil” of a ribbon web will be considered to be one 360° circuit around the rods


11


and


12


. In this regard, it will be noted that the wires


13


and


14


lie along a central axis “X” midway between the rods


11


and


12


and substantially parallel thereto. Thus, for example, a single coil


21


of the web


20


may be considered to start at the axis X, go beneath and around the rod


11


, over the rods


11


and


12


, around and under the rod


12


and back to the axis X, at which point the next coil begins. Thus, for example, referring to the first coil


21


of the web


20


, the coil has a lower outgoing portion or reach


22


(“outgoing” meaning radially outwardly from the axis X), a bend


23


around the rod


11


, an upper incoming portion or reach


24


(“incoming” meaning radially inwardly toward the axis X), a portion


25


at the axis X which will later become a bend, as will be explained more fully below, an upper outgoing portion or reach


26


, a bend


27


around the rod


12


, and a lower incoming portion or reach


28


. Similarly, the coil


31


of the web


30


has reaches


32


,


34


,


36


and


38


and bends


33


,


35


, and


37


.




The coils


21


and


31


, respectively, have leading side edges


29


and


39


in the direction of travel of coils along the rods


11


and


12


, i.e., to the right in FIG.


2


. Because of the helical nature of the coils, it will be appreciated that the leading side edges of adjacent coils of a web are spaced apart along the axis X by the distance of the pitch P. Thus, each of the reaches of a coil, e.g., reaches


24


and


26


of a coil


21


, has a longitudinal axis Y, which is inclined to the axis X at a predetermined acute angle A. This angle will vary with the pitch P of the coils which, in turn, will vary with the number of webs used in the garland. In this regard, in the embodiments illustrated herein, the garland is made up of two ribbon webs


20


,


30


. However, it will be appreciated that the principles of the invention are applicable to garlands utilizing only a single web, in which the case the pitch P will be substantially W. It would also be possible to utilize more that two ribbon webs. It will further be appreciated that the pitch P will vary with the amount of overlap, if any, and the amount of spacing, if any, of adjacent coils. If adjacent coils overlap or are spaced apart, the pitch P will not be an integral multiple of W.




As was mentioned above, the wires


13


and


14


are laid along the axis X, the wire


13


being above the coils


21


,


31


, and the wire


14


being beneath the coils. The filaments


15


,


16


, on the other hand, pass inside the coils


21


,


31


. The wires


13


,


14


are preferably formed of a suitable metal of a gauge preferably as small as possible in order to minimize cost and visibility in the finished product, but sufficiently large that it will retain its twisted configuration. The filaments


15


,


16


, could be monofilaments of a relatively clear plastic material to minimize visibility, or each could be formed of plural strands, such as a suitable yarn, if increased visibility is desired.




It is a fundamental aspect of the invention that the wires


13


and


14


are twisted together along the axis X. In the event that the garland is formed on the machine disclosed in the aforementioned copending application, the wires


13


,


14


would be held at a location to the right of

FIG. 2

, while a twisting force would be applied to the wires at the left of

FIG. 2

, this force preferably being applied in the direction of the arrow in

FIG. 2

, although it could be applied in either direction. Since the coils


21


and


31


of the ribbon webs are disposed between the wires


13


,


14


, the twisting of the wires together also tends to twist the web coils. In the machine of the copending application, the twisting of the web coils is restrained by the rods


11


,


12


, until the coils come off the ends of the rods but, by the use of other apparatus, the twisting of the web coils could occur substantially simultaneously with the twisting of the wires. Preferably, the filaments


15


,


16


, are also held together with the wires at the right-hand holding point, so that the twisting serves to draw the filaments


15


,


16


in toward the axis X and twist them together with the wires


13


,


14


.




In order to understand what happens to the web coils as the wires are twisted, it is helpful to think of the web coils


21


,


31


as being, respectively, divided into half coils or loops


40


,


50


. For example one half coil or loop


40


of a coil


21


of the web


20


would include the reaches


22


and


24


and the intervening bend


23


, while the other half coil or loop would comprise the reaches


26


and


28


and the intervening bend


27


. In general, as the twisting progresses, the loops of a coil, in addition to rotating about the axis X, are folded toward each other about the axis X, forming the bends


25


,


35


. As will be explained more fully below, ultimately, if twisting is continued long enough, the loops will be folded completely together so that they are back-to-back, e.g., with the reach


24


contacting the reach


26


, etc. In the resulting arrangement, each web may be viewed as made up of a series of consecutive folds back and forth between the axis X and a line radially spaced from the axis X. Each reach of a web has inner (at the axis X) and outer ends, respectively joined by bends to adjacent reaches, so that each web is formed of a series of consecutive folds, wherein each “fold” may be viewed as a reach and a bend which joins it to the next fold. For example, the web


20


includes a first fold having reach


22


and bend


23


, a second fold having reach


24


and bend


25


, a third fold having reach


26


and bend


27


, a fourth fold having reach


28


and the next bend


25


, and so forth.




As the wires


13


,


14


are twisted together, the reaches


24


and


26


along the tops of the coils


21


fold toward each other around the wire


13


and, similarly, the reaches


34


and


36


of the web


30


fold toward each other around the wire


13


. Simultaneously, the reach


28


of one coil


21


and the reach


22


of the next coil


21


along the bottoms of the coils fold toward each other around the wire


14


. Similarly, the reaches


38


of the web


30


fold toward the reaches


32


of the next coils


31


around the wire


14


. As this folding occurs, it can be seen that each bend


25


in the web


20


will be in engagement back-to-back with a bend


35


of the web


30


, forming a line of engagement along the axis X, with the filaments


15


and


16


lying respectively on opposite sides of this line of engagement to facilitate in the creasing of the folds at the axis X.




Referring to

FIG. 3

, there is illustrated an embodiment of garland


10


A which results after twisting of the wires


13


,


14


through a predetermined number of twists, which number may vary depending upon the distance between the point at which the wires


13


,


14


are held and the point at which the twisting force is imparted thereto. In the garland


10


A consecutive loops


40


of the web


20


are rotationally spaced from each other about the axis X by a twist angle B, while consecutive loops


50


of the web


30


are similarly spaced. In the garland


10


A, the angle B is substantially 90°, so that four consecutive loops


40


A,


40


B,


40


C and


40


D of the web


20


are arranged in a four-armed cross or star configuration, as are consecutive loops


50


A,


50


B,


50


C and


50


D of the web


30


. Loops with the same letter suffix are axially aligned with each other so that the final garland


10


A has a star or cross configuration. Furthermore, it can be seen that each loop


40


of the web


20


extends radially in a direction diametrically opposite a loop


50


of the web


30


. For example loops


50


A and


40


C extend in opposite directions, loops


50


B and


40


D extend in opposite in opposite directions, and so forth. It can also be seen that alternate reaches of each web have leading side edges spaced apart at the axis X by a distance approximately equal to the web width W. For example the leading side edges


29


of reaches


22


and


26


are spaced apart at the axis X by a distance approximately equal to the width W. The spacing would be less or greater than W to the extent that there is any overlap or spacing of the webs.




If twisting is continued a predetermined number of twists beyond the configuration illustrated in

FIG. 3

, there will result another embodiment of the garland, designated by the numeral


10


B, and illustrated in FIG.


4


. In this embodiment, the adjacent loops of each web have continued to rotate about the axis X and have continued to fold closer to each other so that the angle B between adjacent loops of a web is now approximately 45°. Consecutive loops


40


A through


40


E and


50


A through


50


E are designated in the drawing. In this configuration, the consecutive loops of each web, if viewed from an end of the garland, would define generally an eight-armed star. It is also now more recognizable that the consecutive loops of each web define a helix or spiral about the axis X, the loops


40


forming a helix


45


and the loops


50


forming a helix


55


, so that the garland


10


B has a generally double-helix arrangement of web loops. Each loop


40


of web


20


continues to extend in a diametrically opposite direction from a loop


50


of web


30


.




If twisting of the wires


13


,


14


continues for a further predetermined number of twists beyond the configuration of FIG.


4


, there will result the garland


10


of

FIG. 1

, also illustrated in FIG.


5


. In the garland


10


adjacent loops of each web have been folded completely against each other, so that the angle B has become substantially zero. Thus, for example, the loop


40


B of the web


20


is disposed in abutting back-to-back engagement with both the preceding loop


40


A and the following loop


40


C. Similarly, loop


50


B is in abutting, back-to-back engagement with the preceding loop


50


A and the following loop


50


C of the web


30


. As is best seen in

FIG. 1

, the helices


45


and


55


, respectively formed by the loops of the web


20


and the loops of the web


30


, have become tighter and more clearly defined.




The garland


10


is the most preferred embodiment, both because of this pleasing aesthetic appeal, and because of the fact that, by reason of the adjacent loops of each web being folded against each other, the wires


13


,


14


are concealed. The filaments


15


,


16


will, however, remain visible, assuming they are formed of a material designed to enhance visibility. In the garlands


10


A and


10


B of

FIGS. 3 and 4

, on the other hand, because adjacent loops of each web are still spaced from each other, the wires


13


and


14


are visible, which is normally less aesthetically desirable.




If twisting is continued a further predetermined number of twists beyond the configuration of

FIG. 5

there will result a garland


10


C, having the configuration illustrated in FIG.


6


. The garland


10


C differs from the garland


10


in that the helices


45


and


55


have essentially “unwound” or flattened out, so that all of the loops


40


and


50


lie generally parallel to a common plane, with all of the loops


40


of the web


20


on the one side of the axis X and all of the loops


50


of the web


30


on the opposite side of the axis X.




It will be appreciated that the amount of twist imparted to the garland is infinitely variable, but other variations are not illustrated, since they would not differ substantially in appearance from one of the illustrated embodiments. Furthermore, while in the preferred embodiment two filaments


15


,


16


are utilized, the filaments are not essential and, if desired, either a single filament could be used or the filaments could be eliminated entirely.




As was indicated above, a garland in accordance with the present invention could be formed by utilizing a single ribbon web. Referring to the embodiment of

FIG. 1

, for example, a single-web garland could be formed which is very similar to the garland


10


, except that one of the helices


45


or


55


would be eliminated. In such a single-web garland, there would be no need for two filaments and, therefore, either a single filament or no filament would be used. Variety could be introduced into a single-web garland by, for example, utilizing a ribbon web which has different visual characteristics on its opposite sides.




As was also indicated above, a garland in accordance with the present invention can be formed by utilizing more than two ribbon webs. In that case, the coils of the several webs would be arranged sequentially, and, if they are arranged side by side, with no overlap or spacing, the coils of each web would have a pitch substantially equal to NW, where N is the number of ribbon webs.




The foregoing description has assumed that, in garlands incorporating more than one ribbon web, each web has the same width. However, this need not be the case. Furthermore, the foregoing discussion has assumed that, in plural-web garlands, the webs would not completely overlap, but that also is not essential. For example, a narrow web could be wound directly on top of a wider web, resulting in a single-helix garland, as in the case of a single web, but with a striped effect, assuming the webs are visually distinguishable from each other, the nature of the striping depending upon where along the width of the wide web the narrow web is positioned.




From the foregoing, it can be seen that there has been provided an improved decorative garland which is of simple and economical construction, being formed of readily available commercial materials with no preprocessing, having a unique, aesthetically appealing appearance, which is capable of wide variation by varying a single parameter of the formation method.




While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. The actual scope of the invention is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
