Title: Woven chair

Description:
BACKGROUND OF THE INVENTION  
      This invention relates in general to the field of furniture constructed with structural frames and woven materials, and more particularly, to furniture constructed with frames featuring elements adapted to permit the woven material to remain in a tight configuration, even after extended use. The frame of the present invention also includes features permitting the woven material to completely cover the frame, and not leave gaps in the woven material where the frame may be exposed.  
      Natural wicker has been used in the manufacture of furniture, baskets, and other articles for many centuries. Natural wicker articles are conventionally manufactured from the twigs or branches of various plants. The twigs and branches are first soaked in water to make them pliable, then woven to form an article which holds form once the twigs and branches are permitted to dry. Furniture manufactured from wicker offers great comfort due to wicker&#39;s natural compliancy. Further, wicker is light weight and reasonably strong, making it especially suited for manufacture of furniture.  
      The popularity of wicker furniture continues to increase. The casual, informal appearance of wicker has made it especially popular for use in enclosed porches and other informal settings in homes, hotels, and other establishments. Natural wicker, however, has had limited use in the outdoor furniture market, including patio furniture, pool furniture, and the like. This disfavor is partially due to natural wicker&#39;s tendency to soften and weaken when wet, as the natural material regains some of its pliancy. In addition, after being moistened, natural wicker is more susceptible to rotting and promoting mildew growth than many other natural and synthetic furniture materials.  
      Woven wicker typically comprises a warp yarn, i.e., a yarn running straight through the woven material between a frame to provide support and a weft yarn, i.e., a yarn used as a filler material that is woven around the warp yarn. Numerous styles of weave are used in the manufacture of wicker furniture. The various styles of weave result in different looks, feels, strengths, and weights of the finished woven product. In a simple weave pattern, the warp yarns are spaced apart and arranged parallel to each other. The weft yarns are then woven over and under the warp yarns in an alternating pattern. Adjacent weft yarns pass on opposite sides of a given warp yarn. Variations of this pattern, such as passing the weft yarn over two adjacent warp yarns, are also known in the art.  
      Various synthetic yarns have now been introduced to manufacture wicker-like furniture. As in the case of natural wicker, the synthetic yarns are woven into a woven material of warp and weft weaves within a structural frame. Typically, the structural frame is manufactured from various metals or alloys thereof. Such synthetic materials may be more environmentally stable than typical natural wicker. Given the stable characteristics of the synthetic materials used, such furniture featuring synthetic yarns have found popularity in the-outdoor furniture market, including patio furniture, pool furniture, and the like. The synthetic yarn woven material has also been found popular for indoor use.  
      Notwithstanding this newfound popularity, it has been found that the conventional weave patterns utilized for manufacturing furniture, and particularly chairs, tend to become loosened over time. This slackening of the weave material is aesthetically unpleasing, as the previously consistent overall look of the article may be compromised. In severe cases, the slackening of the weave material may adversely affect the structural integrity of the article of furniture by leaving large gaps in the weave pattern.  
      In the case of woven chairs, the seat portion is particularly susceptible to such slackening as the weight of individuals utilizing the chairs may stretch the synthetic warp and weft material over the course of repetitive use. Even if the warp and weft material&#39;s actual length remains constant, conventional frames and weaving techniques may cause the material to work its way tighter and tighter around the frame, thus loosening the interior portions of the weave. In addition, conventional frames and weave patterns typically leave gaps in the weave where the frame is exposed. These gaps are considered unsightly and tend to increase in size through use of the article.  
      The present invention has arisen to solve the need for a furniture, frame which supports a weave system having features that prevent the weave system from slackening, and which creates and overall more aesthetically appealing article of furniture by, for example, completely covering the frame and not leaving any sizeable gaps.  
     SUMMARY OF THE INVENTION  
      The present invention overcomes the shortcomings of the prior art by providing, in various combinations, a woven chair having a novel frame and novel weave system, which substantially hides the frame from view and limits slackening of the weave pattern.

     DETAILED DESCRIPTION  
      In the following are described the preferred embodiments of the woven chair in accordance with the present invention. In describing the embodiments illustrated in the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. Where like elements have been depicted in multiple embodiments, identical reference numerals have been used in the multiple embodiments for ease of understanding.  
      The woven chair of the present invention improves on the prior art by providing for a woven chair that is configured to prevent the woven material from slackening, and is configured to provide a tight nearly gapless weave that hides the frame.  
      A perspective view of a partially completed woven chair is shown in  FIG. 1 . As shown, the woven chair  100  may comprise a frame  102  covered with woven material  104 , as is conventionally known in the art. It will be appreciated that the woven chair depicted in  FIG. 1  is only partially complete, with the woven material consisting of both weft and warp weaves on the finished side  106  and only warp weaves on the unfinished side  108 . As shown on the finished side, the woven chair  100  is bounded by a finished edge  110 . As will be discussed, the use of a frame  102  comprising multiple parallel bars permits the finished edge to be weaved to a very tight configuration, with very few visible gaps.  
       FIG. 2  depicts a cut-away view of the finished side  106  of woven chair  100  depicting a detail of finished edge  110  in accordance with certain aspects of the present invention. The woven material  104  comprises warp yarn  112  and weft yarn  114  weaved together. The warp yarn  112  is typically a yarn running straight through the woven material between a frame  102  to provide support while the weft yarn  114  is used as a filler material that is woven around the warp yarn. The warp yarns  112  are typically woven first, with the weft yarns  114  then woven over and under the warp yarns in an alternating pattern. Adjacent weft yarns  114  pass on opposite sides of a given warp yarn  112 . Variations of this pattern may also be utilized.  
      It will be appreciated that the woven material  104  of  FIG. 2  is tight and completely full, such that only very small gaps  116  are formed. This tight weave is achieved, as will be discussed, through the novel use of a frame  102  having multiple parallel bars. In the prior art, such frames were not known.  
      For example,  FIG. 3  depicts a cut-away view of the finished side  106 ′ of a woven chair  100 ′ as known in the prior art. In this example, and although not shown, the frame includes only a single bar. Because of this frame configuration, the weft yarn  114 ′ must be woven around the finished edge  110 ′ without any warp yarn  112 ′, leaving large gaps  116 ′. The large gaps  116 ′ are not only unsightly, but also tend to permit the woven material  104 ′ to sag over time. This compromises the structural integrity of the woven chair  100 ′, and is undesirable.  
       FIG. 4  depicts a cut-away view of the finished side  106 ″ of a woven chair  100 ″ in accordance with one aspect of the present invention. In this example, and although not shown, the frame includes two parallel bars. Owing to this frame configuration, the weft yarn  114 ″ may be woven around both bars at the finished edge  110 ″ to pull the weft yarn tighter than may be achieved with a single bar. This contributes to a reduction in the size of the gaps over the single bar prior art woven chair  100 ′, shown in  FIG. 3 . Notwithstanding, the use of a two bar frame still prevents the weaving of a warp yarn in the finished edge  110 ″ area, thus allowing some gaps  116 ″ in the woven material  104 ″. As such, it will be appreciated that the three bar configuration is the most preferred embodiment of the present invention.  
      Shown in  FIG. 5  is a frame  102  constructed in accordance with the aforementioned and preferred three bar arrangement. As shown, the frame  102  includes a main frame  120  at the exterior-most limits. The main frame  102  comprises a first end bar  122  and second end bar  124 , each spanning between opposed first and second side bars  126 ,  128 . Each of the bars forming the main frame  120  are preferably cylindrical, with a consistent diameter. The bars are preferably formed from metal or alloys thereof, with the connections between bars preferably being welded. Other materials may also be utilized, as discussed below.  
      Offset from the first end bar  122 , and spanning between the first side bar  126  and second side bar  128 , is a first end secondary bar  130 . Similarly, offset from the second end bar  124 , and spanning between the first side bar  126  and second side bar  128  is a second end secondary bar  132 . The first end secondary bar  130  and second end secondary bar  124  are preferably formed from the same material as the bars of the main frame  120  and may be connected thereto by the same connection means used to connect the bars of the main frame. Similarly, the first end secondary bar  130  and second end secondary bar  132  are preferably cylindrical, although preferably with a diameter of less than that of the bars of the main frame  120 .  
      Also offset from the first end bar  122 , and spanning between the first side bar  126  and second side bar  128 , is a first end tertiary bar  134 . The first end tertiary bar  134  is preferably mounted between the first end bar  122  and first end secondary bar  130 . Similarly, offset from the second end bar  124 , and spanning between the first side bar  126  and second side bar  128  is a second end tertiary bar  136 . The second end tertiary bar is preferably mounted between the second end bar  124  and the second end secondary bar  132 . The first end tertiary bar  134  and second end tertiary bar  136  are also preferably cylindrical, with a diameter sized between that of the end bars  122 ,  124  and secondary bars  130 ,  132 .  
      Although the tertiary bars  134 ,  136  span the first side bar  126  and second side bar  128 , and may be attached to the side bars by the same connection means used to connect the bars of the main frame, the tertiary bars may also be attached to the first end bar  122  and second end bar  124  by filler bars  138 . Preferably, four such filler bars are utilized, although the total number may vary. The fillers bars are typically also cylindrical, and may be of a diameter similar to that of the tertiary bars  134 ,  136 .  
      As further shown in  FIG. 5 , the frame  102  may comprise a back area  140  and a seat area  142 , to form the back and seat portions of the finished woven chair  100 . As in a conventional chair, the back area  140  is configured to be a generally vertical plane in the finished product with the seat area  142  being a generally horizontal plane. A person may therefore sit upon the seat area  142  while resting their back against the back area  140 . It will be appreciated, therefore, that the first side bar  126  and second side bar  128  may be configured in curvilinear fashion to bend into a generally L-shaped composition to help form the seat area  142  and back area  140 , as best shown in  FIG. 1 .  
      It is also shown in  FIG. 5  that the back area  140  and seat area  142  may be separated by a rear support strut  144  spanning between the second side bar  128  and first side bar  126 . The rear support strut  144  is preferably formed from the same material as the bars of the main frame  120  and may be connected thereto by the same connection means used to connect the bars of the main frame, preferably welding in the case of metallic bars. Further, the rear support strut  144  may be formed to approximately the same diameter as the bars of the main frame  120 . One function of the rear support strut  144  is to provide for structural support of the frame  102 , and not necessarily to have woven materials woven directly thereto.  
      The frame  102  may also comprise a front support strut  146  extending between the first side bar  126  and second side bar  128 , toward the front of the seat area  142  near the second end bar  124 . The front support strut  146  may be formed to approximately the same diameter as the bars of the main frame and  120  and the rear support strut  144 . In addition, the front support strut is preferably formed from the same material as the bars of the main frame  120  and may be connected thereto by the same connection means used to connect the bars of the main frame, preferably welding in the case metallic bars. The front support strut  146  is typically utilized as a structural support for the main frame  120 , but may also be used to support other bars.  
      Such bars include a seat area first side secondary bar  148 . The seat area first side secondary bar  148  may extend between the front support strut  146  and the first side bar  126 . Preferably, the seat area first side secondary bar  148  extends generally parallel to the first side bar  126 , and attaches thereto in the back area  140 , after bending toward the first side bar  126  in the general vicinity of the rear support strut  144 . The seat area first side secondary bar  148  may also be connected to the first side bar  126  by one or more filler bars  138 .  
      Similarly, a seat area second side secondary bar  150  may extend between the front support strut  146  and the second side bar  128 . Preferably, the seat area second side secondary bar  150  extends generally parallel to the second side bar  128 , and attaches thereto in the back area  140  after bending toward the second side bar  128  in the general vicinity of the rear support strut  144 . The seat area second side secondary bar  150  may also be connected to the second side bar  128  by one or more filler bars  138 .  
      In addition to the seat area first side secondary bar  148  and the seat area second side secondary bar  150 , a back area first side secondary bar  152  and a back area second side secondary bar  152  may extend parallel to the fist side bar  126  and second side bar  128 , respectively. In this regard, the back area first side secondary bar  152  may connect to the first side bar  126  in the back area  140 , and then bend to extend parallel to the first side bar until the back area first side secondary bar culminates at a connection with the first end secondary bar  130 . The back area second side secondary bar  154  may connect to the second side bar  128  in the back area  140 , and then bend to extend parallel to the second side bar until the back area second side secondary bar culminates at a connection with the first end secondary bar  130 . The back area first side secondary bar  152  and the back area second side secondary bar  154  may also be connected to the first side bar  126  and second side bar  128 , respectively, by one or more filler bars  138 .  
      Each of the seat area first side secondary bar  148 , seat area second side secondary bar  150 , back area first side secondary bar  152 , and back area second side secondary bar  154  may be of a diameter similar to that of the first end tertiary bar  134  and second end tertiary bar  136 . Further, the seat area first side secondary bar  148 , seat area second side secondary bar  150 , back area first side secondary bar  152 , and back area second side secondary bar  154  are preferably formed from the same material as the bars of the main frame  120  and may be connected thereto and to the front support strut  146  or first end secondary bar  130 , as appropriate, by the same connection means used to connect the bars of the main frame, preferably welding in the case of metallic bars.  
      As also shown in  FIG. 5 , the frame  102  may include a plurality of attachment mechanisms from attaching the frame  102  to a base. In preferred embodiments, the attachment mechanisms are bosses  156 . Preferably, four total bosses are included, two in the back area  140  and two in the seat area  142 . The bosses may be welded to the first side bar  126  or second side bar  128 , and may include internally tapped threads (not shown). The bosses  156  may be utilized to attach the frame  102  to a chair base (not shown), such that the woven chair  100  may be completed. Bases appropriate for connection to the frame  102  are well known in the industry, and typically include a frame structure having four legs for stability.  
       FIG. 6  depicts a blow-up view of a portion of  FIG. 5 , showing the first end bar  122 , first end secondary bar  130 , and first end tertiary bar  134 , among other features of the frame  102 , in greater clarity. Although not necessarily to scale, in this view one may appreciate the relative diameters of the respective bars, and their general locations within the frame  102 .  
      In order to weave the warp yarn  112  and weft yarn  114  into woven material  104  covering the frame  102 , the practitioner may utilize any number of weaving patterns. An exemplary weaving pattern is disclosed herein as follows. Although the weave pattern discussed in the following begins at a location near the rear support strut  144 , it will be appreciated that the start point may be anywhere along the first side bar  126  or second side bar  128 . The weave pattern may also be stopped and restarted at various locations.  
      As shown in  FIG. 7 , depicting a blown-up view of the woven chair  100  in the area of the intersection of the first side bar  126  and rear support strut  144 , a practitioner P may tie a knot  158  around the seat area first side secondary bar  148  with warp yarn  112 . The practitioner P may then thread the warp yarn  112  under the first side bar  126 , as shown by arrow A in  FIG. 7 . Preferably, the warp yarn  112  is grouped in a set of three parallel strands, such that three strands are stitched simultaneously and directly adjacent to each other in a tight configuration. In other embodiments, a single strand or two strands may be utilized. In still other embodiments, greater than three strands may also be used.  
      Moving to  FIG. 8 , it is shown that the warp yarn  112  may then be brought over the first side bar  126  and seat area first side secondary bar  148  and across the seat area  142  of the woven chair  100  toward the second side bar  128  (not shown in  FIG. 8 ), along the direction indicated by arrow B.  
      As shown in  FIG. 9 , depicting a blown-up view of the woven chair  100  in the area of the intersection of the second side bar  128  and rear support strut  144 , the practitioner may then extend the warp yarn  112  over the second side bar  128  along arrow C. Once so extended, the warp yarn  112  may then be brought under the second side bar  128  and seat area second side secondary bar  150  toward the seat area  142  of the woven chair  100 . The warp yarn  112  may then be dropped down toward the second end bar (not shown in  FIG. 9 ) and brought back over the seat area second side secondary bar  150  and the second side bar  128  along arrow D, to the position shown in  FIG. 9 .  
      As shown in  FIG. 10 , depicting the same view as  FIG. 9 , the warp yarn  112  may be brought back under the second side bar  128  along arrow E toward the seat area  142 , and then brought up between the seat area second side secondary bar  150  and the second side bar  128 . The warp yarn  112  may then wrapped around the seat area second side secondary bar  150  one time and then brought under the seat area second side secondary bar and the second side bar  128  along arrow F to the position shown in  FIG. 10 .  
      The warp yarn  112  may then be brought over the second side bar  128  and second side secondary bar  150 , across the seat area  142 , to the first side bar  126 , where the weaving pattern is repeated bringing the warp yarn back to the second side bar  128 . The weaving pattern is again repeated leaving the yarn configuration shown in  FIG. 11 . It will be appreciated that wrapping of the warp yarn  112  around the seat area second side secondary bar  150  and the seat area first side secondary bar  148  as discussed offsets parallel groups of three strands of warp yarn such that a gap  116  is left for the later weaving of the weft yarn  114 , as will be discussed.  
      This stitching pattern may be repeated continuously until the entire seat area  142  and back area  140  are stitched with warp yarn  112 . A partially stitched woven chair  100  is shown in  FIG. 12 . Throughout this repetitious stitch pattern, it will be appreciated that the warp yarn  112  need not be a continuous strand. Rather, as lengths of warp yarn  112  reach their limits, the length may be glued or tied to one of the first side bar  126  or second side bar  128 , and another strand started just adjacent thereto. In addition, as previously discussed, the warp yarn  112  weaving pattern may begin at various chair locations.  
      Once the entire chair is stitched with warp yarn  112 , stitching of the weft yarn  114  to create the woven material  104  of the woven chair  100  may begin. As shown in  FIG. 13 , the weft yarn  114  may be woven in a direction perpendicular to the warp yarn  112 , over and under the warp yarns in an alternating pattern. Adjacent weft yarns  114  may therefore pass on opposite sides of a given warp yarn  112  in a tight configuration to leave very small gaps  116 . Preferably, the gaps are small enough that one may not readily see the bars underneath, including the first side bar  126  and seat area first side secondary bar  148 , identified in  FIG. 12  with dashed lines for clarity.  
      To create the woven material  104  of the woven chair  100  referenced above, stitching of the weft yarns  114  may begin at the first end bar  122 , as shown in  FIG. 14 . In this regard, the weft yarn  114  may be glued to the first end bar  122  at an end  115  of the weft yarn. Suitable glues include those glues identified above as being appropriate for the warp yarn  112 .  
      The weft yarn  114  may then be brought over the first end bar  122  along arrow G and then behind the backside of the first end bar to the first end secondary bar  130 . The weft yarn  114  may then be brought over the first end secondary bar  130  along arrow H and threaded under the first end tertiary bar  134  and adjacent the first end bar  122  along arrow I to the position shown in  FIG. 14 .  
      Once in the position shown in  FIG. 14 , the weft yarn  114  may then be brought toward the back area  140  of the chair over the first end tertiary bar  134  along arrow J. The weft yarn  114  may then be brought under the first end secondary bar  130  along arrow K and back over the first end bar  122  toward the back area  140  along arrow L, as shown in  FIG. 15 .  
      Once facing the direction of the back area  140  following this procedure, the weft yarn  114  may be threaded between the warp yarns  112  and through the entire back area and seat area  142  until reaching the vicinity of the second end bar  124 , where the pattern is repeated such that the weft yarn is stitched around the second end bar  124 , second end secondary bar  132 , and second end tertiary bar  136 . After repeating the pattern, the weft yarn may then be brought back up toward the first end bar  122 , by again weaving between the warp yarns  112  through the seat area  142  and back area  140 . It will be appreciated that multiple passes of this pattern will fill in the frame  102  of the woven chair  100 , to create the woven material  104 .  
      Preferably, when weaving the weft yarn  114 , successive passes are brought directly adjacent the previously threaded pass, such that the weft yarn being threaded is tight against the woven material  104 .  
       FIG. 16  depicts a detail of a corner of the frame  102 , where the first end bar  122  meets the first side bar  126 . It will be appreciated that in order to create a smooth finish to the woven material  104 , the weft yarn  114  brought up to the first end bar  122  along the first side bar  126  may be trimmed at an end  160  and tucked under adjacent weft yarn, such that the ends  160  are hidden from view.  
      Although the bars of frame  102  have been described as being formed from metals or alloys thereof with welded ends, it will be appreciated that various other materials and suitable connections may be utilized. For example, the bars may be formed from structurally appropriate plastics with glued, chemical welded, or mechanically secured end connections. Various other more exotic materials may also be utilized, such as composites including fiberglass or carbon fiber. Combinations of these materials may also be utilized to take advantage of the strengths of each. For example, a fiberglass bar may be laminated and joined with metallic ends, such that the metallic ends may then be welded whereas fiberglass cannot.  
      The weft and warp yarns are typically synthetic, as known in the industry.
