Description

    BACKGROUND OF THE INVENTION
  • This invention relates generally to articles of furniture, and more particularly, to foldable chairs that are adjustable to accommodate being used on varying terrain.
  • Spectators at outdoor events, such as sporting events, fireworks displays, and/or beachgoers, often use portable, foldable lawn furniture for seating during their time at such locations. At such locations, seating is commonly placed on grassy areas, beaches, or other terrain that may not be flat. Depending on the terrain of the ground, it may be difficult to set the furniture in a position that provides comfort to the user.
  • To accommodate uneven or sloped ground, at least some known portable furniture includes an adjustment mechanism that facilitates keeping the seat of the chair roughly parallel relative to the horizontal and to the ground upon which the chair is situated. For example, U.S. Pat. No. 5,494,333 to Wilson describes a chair which includes three or four adjustable legs. However, the number of adjustment positions is fixed, such that sloped terrain usage may be limited. Other known adjustable chairs include individually adjustable legs that are not adjustable by a seated user. In addition, other known adjustable chairs include adjustment mechanisms that are fairly complicated assemblies that are difficult to use and/or assemble, that are costly, that are positioned such that they limit an amount of folding of the chair for storage, and/or that must be manually readjusted each time the location of the chair is changed. Moreover, depending on the materials used in fabricating the adjustment mechanisms, over time the tolerances between moving components may loosen, thus reducing the effectiveness of such mechanisms.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 1 is a perspective view of an exemplary foldable chair 10 in an open position 12. FIG. 2 is side view of chair 10 in a closed or storage position 14. FIG. 3 is an enlarged view of a portion of chair 10. In an alternative embodiment, chair 10 includes a pair of rocker rails. Moreover, as one of ordinary skill in the art will appreciate, the present invention may be adapted for use with a plurality of different chairs and other furniture without departing from its scope. As such, the present invention is not limited to any particular article of furniture.
  • As best seen in FIG. 1, chair 10 includes a plurality of jointed members 20 that are pivotally coupled together with respect to each other. Specifically, in the exemplary embodiment, chair 10 includes a pair of rear side frame members 22 and a pair of forward side frame members 30. In the exemplary embodiment, the rear side frame members 22 are substantially identical, and, as described in more detail below, are oriented in a mirrored relationship with respect to each other. Similarly, in the exemplary embodiment, the forward side frame members 30 are substantially identical, and, as described in more detail below, are oriented in a mirrored relationship with respect to each other.
  • In the exemplary embodiment, members 22 and members 30 are coupled together by a pair of arm-support members 36 and by a pair of adjustment members 38, as described in more detail below. Specifically, in the exemplary embodiment, each arm-support frame member 36 is pivotally coupled to each member 30 in proximity to an upper end 40 of each member 30, and to each member 22 in proximity to a mid-point region 42 of each member 22. As used herein, the term “midpoint region 42” refers to an area of each member 22 that is approximately midway between an upper end 46 and a lower end 48 of each member 22.
  • Members 22 are also coupled together in the exemplary embodiment by a lower structural support member 50 and by an upper structural support member 52. More specifically, in the exemplary embodiment, structural support member 50 is fixedly secured to each member 22 at the lower end 48 of each member 22, and structural support member 52 is coupled to each member 22 at the upper end 46 of each member 22. Members 50 and 52 provide structural support to members 22 and to chair 20. Moreover, because members 50 and 52 each have approximately the same length L1, in the exemplary embodiment, members 50 and 52 facilitate maintaining members 22 in position relative to chair 20. Alternatively, members 50 and 52 may be fabricated with different lengths L1. Specifically, in the exemplary embodiment, members 22 are coupled to members 50 and 52 at approximately the same relative location with respect to the length L1 of members 50 and 52, such that members 50 and 52 facilitate maintaining members 22 in a spaced-apart mirrored orientation, wherein the members 22 are substantially parallel to each other and are substantially perpendicular to each member 50 and 52.
  • Similar to members 22, members 30 are coupled together in the exemplary embodiment by a lower structural support member 60 and by an upper structural support member 62. More specifically, in the exemplary embodiment, structural support member 60 is fixedly secured to each member 30 adjacent a lower end 64 of each member 30, and structural support member 62 is coupled to each member 30 adjacent the upper end 40 of each member 30. Members 60 and 62 provide structural support to members 30 and to chair 20. Moreover, because members 60 and 62 each have the same length L2, in the exemplary embodiment, members 60 and 62 facilitate maintaining members 30 in position relative to chair 20. Alternatively, members 60 and 62 may be fabricated with different lengths L2. Specifically, in the exemplary embodiment, members 30 are each coupled to members 60 and 62 at approximately the same relative location with respect to the length L1 of members 60 and 62, such that members 60 and 62 facilitate maintaining members 30 in a spaced-apart mirrored orientation, wherein the members 30 are substantially parallel to each other and are substantially perpendicular to each member 60 and 62.
  • In the exemplary embodiment, members 60 and 62 also facilitate maintaining members 30 in proper alignment and orientation with respect to members 22. More specifically, in the exemplary embodiment, members 30 and members 22 are oriented substantially parallel to each other and such that each member 30 is spaced a distance D1 outward from each respective member 22. Distance D1 is measured between an outer surface 70 of each respective member 22 to an inner surface 72 of each respective member 30.
  • In the exemplary embodiment, because members 22 are coupled a distance D1 from members 30, rear side frame members 22 are not coupled directly to front side frame members 30, but rather members 22 and members 30 are each pivotally coupled to arm-support member 36 and to adjustment members 38, as described in more detail below. As such, members 22 and members 30 may move, relative to each other, without contacting each other. More specifically, each rear side frame member 22 is rotatably coupled to an aft end 80 of each arm-support member 36 at a pivot point 82 and is also rotatably coupled to a forward end 84 of each adjustment member 38 at a pivot point 86. Moreover in the exemplary embodiment, each front side frame member 30 is rotatably coupled to a forward end 90 of each arm-support member 36 at a pivot point 92 and is slidably and rotably coupled at an adjustment coupler point 93, as described in more detail below, located adjacent an aft end 94 of each adjustment member 38.
  • In the exemplary embodiment, a seat 100 fabricated from a sheet of flexible material, such as a cloth material, is suspended from chair 10. Specifically, an upper end 102 of seat 100 is suspended from upper structural support member 52, and a lower end 104 of seat 100 is suspended from lower structural support member 62. More specifically, in the exemplary embodiment, each seat end 102 and 104 is folded about its respective structural support member 52 and 62, and is then coupled to itself, such as through a sewing process. Alternatively, seat 100 may be coupled to each support member 52 and 62 using any coupling method that enables seat 100 to function as described herein. Moreover, seat 100 may be fabricated from any material that enables chair 10 to function as described herein. In the exemplary embodiment, seat 100 is suspended between a pair of arm rests 110 that are each coupled to a respective arm-support member 36.
  • As best illustrated in FIG. 3, each front side frame member 30 is slidably and rotably coupled at an adjustment coupler point 93 that is located adjacent to an aft end 94 of each adjustment member 38. More specifically, in the exemplary embodiment, each adjustment member 38 includes a coupling slot 120 formed therein that extends from an outer surface 122 to an inner surface 124 of each member 38. In the exemplary embodiment, each slot 120 is substantially linear and is formed with a substantially constant height h1 that extends along the full length L3 of each slot 120. Slot length L3 is measured in the exemplary embodiment between opposed ends 125 and 127 of slot 120. Moreover, in the exemplary embodiment, each slot 120 is substantially centered within each respective member 38. In an alternative embodiment, slot 120 may have any non-linear shape, such as, but not limited to, a stepped shape, that enables chair 10 to function as described herein. Moreover, in an alternative embodiment, each slot 120 may be defined at any location within each member 38. In another alternative embodiment, a plurality of slots 120 may be defined within each member 38.
  • In the exemplary embodiment, member 22 is rotatably coupled to each arm-support member 36, at pivot point 82, and to each adjustment member 38, at pivot point 86, with a mechanical faster 130. Moreover in the exemplary embodiment, each front side frame member 30 is coupled to each arm-support member 36, at pivot point 92, and to each adjustment member 38, at adjustment coupler point 93, with mechanical fastener assemblies 130. For example, in the exemplary embodiment, mechanical fastener assemblies 130 include rounded bolt heads 132 and washer/nuts 134. Alternatively, any other suitable fastener mechanism that enables chair 10 to function as described herein may be used.
  • In particular, as best illustrated in FIG. 3, with respect to adjustment coupler point 93, the bolts 132 are inserted through slots 120 such that the rounded heads 136 of the bolts 132 are adjacent the inner surface 124 of each member 38. Moreover, because each bolt head 136 has a diameter D2 that is larger than slot height h1, bolts 132 are prevented from sliding through slot 120. Bolts 132 are then maintained in slidable contact within slots 120 by nuts 134. Specifically, with respect to coupler point 93, when adjustment member 38 is moved, each bolt 132, when secured within slot 120, is slidable between the opposed ends 125 and 127 of slot 120, and chair members 22 and 30 are rotatably coupled at each pivot point 82, 92, 86, 93, and 94, about each fastener assembly 130.
  • During use, when a user is seated on chair 10, in a location of substantially even terrain, the bolts 132 within each adjustment slot 120 typically remain generally centered within each slot 120 with respect to the length L3 of slot 120. Moreover, in such a seated orientation, when the user selectively shifts their weight forward and aft, the adjustment slots 120 facilitate imparting a rocking chair motion to chair 10. Alternatively, when a user is using chair 10 on a location of sloped or non-even terrain, slots 120 facilitate “leveling” chair 10. Specifically, slots 120 may enable the lower ends 48 of members 22 to be supported at an terrain elevation that is lower than the elevation of the terrain supporting the lower ends 64 of members 30, or vice-versa, without causing the relative orientation of seat 100 to be significantly altered as compared to when chair 10 is used on substantially level terrain. As a result, the tendency of chair 10 to be inadvertently tipped over by a seated user is facilitated to be reduced in comparison to chairs not including such adjustment members 38.
  • When chair 10 is folded for storage into folded position 14, slots 120 facilitate enabling members 22 and 30 to be positioned substantially parallel to each other, such that each member 30 is radially inward from each member 22. As such, slots 120 facilitate chair 10 being folded into a substantially “flatter” storage position 14 than is generally possible with other sling style foldable chairs. Moreover, during folding for storage into position 14, structural support member 52 facilitates preventing the over-rotation of member 30 with respect to member 22.
  • Exemplary embodiments of foldable furniture including adjustment slots are described in detail above. The adjustment slots described herein are not limited for use with the chair described herein, but rather, the adjustment slots can be utilized independently and separately from other chair components described herein. Moreover, the invention is not limited to the embodiments of the chair described above in detail. Rather, the present invention may be used with other variations of foldable furniture within the spirit and scope of the claims.
  • While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
