FURNITURE SEATING SURFACE
A seating surface comprising: a perimeter rim surrounding an opening, a first cord spanning the opening, a second spanning the opening and arranged to cross over the first cord at a cord crossover location within the opening, a pebble having a first surface and a second surface axially opposed to the first surface. The pebble is axially sandwiched between the first and second cords at the cord crossover location such that the pebble is axially retained between the first and second cords.
The present invention relates to a furniture seating surface, where the seating surface is suspended by cords. The seating surface includes a rigid or semi-rigid “pebble” that is sandwiched between two spans of cord. Preferably, the seating surface is comprised of a plurality of such pebbles serving to create a comfortable seating surface that minimizes any sharp or concentrated contact loads against the user.
(2) Description of the Related ArtHeretofore, suspended seating surfaces have included cords stretched across an opening surrounded by a perimeter frame. These cords are commonly circular in cross section. The circular surface bears against the user to support his/her weight when seated. This circular surface effectively creates a narrow area of contact, which results in regions of high contact stress (i.e. “pressure point”) and discomfort for the user. In an effort to reduce this contact stress, some of these cord-based seating surfaces have increased the number of cords in a given area of seating surface. This only partially improves the comfort, while also significantly increasing the manual labor involved in manually “stringing” the seating surface.
Additionally, it is noted that the external surface of these cords serve to create the seating surface that contacts the user. These cords are commonly composed of thin fibers or filaments. These individual fibers commonly have low resistance to abrasion, which means that the cords will be abraded and degraded with use due to the constant movement of the user against the cord surface. Over time, this abrasion and fiber breakage significantly weakens the cords and also results in an unappealing “fuzzy” surface as these fibers are broken and splayed. As such, it is common for corded seating surfaces to be re-strung and restored.
SUMMARY OF THE INVENTIONWhile the seating surface of the present invention includes cords, there are also “pebbles” sandwiched between these cords. The cords are nested in channels of the pebble(s) such that the cord is recessed and protected by the pebble such that the surface of the pebble provides the primary region of contact between the user and the seating surface.
In accordance with the present invention, it has now been found that the forgoing objects and advantages may be readily obtained.
The surface area of the pebble may be designed in any size and/or configuration desired and may preferably include a broad and smooth surface area of contact with the user. In comparison with the narrow circular surface of the prior-art corded seating surface, the seating surface of these pebbles serves to significantly broaden and increase the area of contact, which correspondingly reduces the contact stress and results in increased comfort of the user, virtually eliminating the “pressure points” of conventional corded seating surfaces.
Further, the seating surface is preferably segmented into an array of these pebbles such that the individual pebbles are each suspended such that they may independently tilt and flex to create a conformable seating surface, for even greater comfort of the user.
Still further, since the pebbles may be constructed in a variety of materials and finishes, the pebbles may be designed to have extremely high durability and abrasion resistance for far greater longevity than corded seating surfaces.
Yet further, the array of pebbles may have a wide range of shapes, contours, materials, finishes, colors, etc. This provides the designer with a broad palette of aesthetic options for the seating surface. As such, the aesthetic potential for the present invention far exceeds that of a corded seating surface.
Further features of the present invention will become apparent from considering the drawings and ensuing description.
The present invention will be more readily understandable from a consideration of the accompanying exemplificative drawings, wherein:
The vertical axis 22 is shown here to extend in a vertical direction that is perpendicular to the horizontal seating surface 12 as shown, with a vertically upward direction 24a and a vertically downward direction 24b. The term “vertical” is used here to describe an alignment generally perpendicular to the generally horizontal seating surface 12 shown in
The term “pebble” is defined herein as a rigid or semi-rigid solid element that may be made from a variety of materials such as wood, stone, rubber, plastic, among others. Such a “pebble” need not necessarily be formed of stone or mineral material. It is preferred that the “pebble” has rounded or softened edges on surfaces that face the user to provide maximum user comfort. The “pebble” may have a variety of shapes and contours that may be desired for ergonomic and/or aesthetic purposes. It may be preferable that the “pebble” be a generally flat element having a lateral width 65 greater than its axial height 67 (as is shown in pebble 12) to have greater surface area in contact with the user, while minimizing the amount of crimp in the cord 18 when extending between adjacent pebbles. The pebbles described herein may also be considered as tiles and are shown here to preferably be arranged in a generally planar array.
As detailed in
It is noted that, in the plan view of
As particularly shown in
Next, the pebbles 16 may each be inserted in between the warp span 19a and weft span 19b at respective crossover locations 36 such that the upper of the two spans is nested in the top channel 44 and the lower of the two spans is nested in the bottom channel 46 as particularly shown in
The nesting between warp spans 19a and weft spans 19b in their respective top channels 44 and bottom channels 46 serve to align and laterally key the pebbles 16 to both the warp spans 19a and weft spans 19b. This keyed engagement serves to limit lateral displacement of the pebbles 16 in both the warp direction 30 and weft direction 32 and to laterally stabilize the entire seating surface 12 within the perimeter rim 20. Additionally, the pebbles 16 and their floor surfaces 45 and 47 are vertically captured and sandwiched between the warp spans 19a and weft spans 19b, thus limiting any vertical displacement therebetween. Crossover locations 36 are also laterally aligned with crossover locations 52.
The warp spans 19a and weft spans 19b may be considered as tensile elements that are suspended across the perimeter rim 20. The cord 18 is preferably flexible enough to provide some resilience to these spans, thus providing a small degree of elastic stretch and deflection under load so that the seating surface 12 may conform to the contours of the user for optimum user comfort while seated on the stool 10. Since the pebbles 16 are laterally locked and axially sandwiched within the grid 59, the pebbles 16 will follow any vertical displacement of the cord 18 under the user. As such the seating surface 12 will correspondingly conform and match (to some degree) to the contours of the user.
As particularly shown in
If the user were to sit directly on the grid 59 without the pebbles 16 inserted, the narrow surface area of the bare cord 18 results in high contact stress against the user and would impinge and jab the user, resulting in a relatively uncomfortable seating experience for the user. However, with the inclusion of the pebbles 16 as shown in
It is noted that the pebbles 16 also provide a pleasing aesthetic appearance to the seating surface 12, which is a prominent visual aspect to the stool 10. In comparison with the grid 59 alone, the pebbles add a visual interest and significant aesthetic enhancement to the stool 10. Furthermore, the array of pebbles 16 of the seating surface 12 provide a graphical canvas that may take on many forms.

While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as exemplifications of embodiments thereof. For example:
The stool 10 is a simple seating typology and is representative of a wider range of seating furniture types, such as chairs, benches, lounges, settees, sofas, and the like. The present invention may be utilized to provide a seating surface in applications that include the wider range of seating furniture types.
Further, this arrangement, where pebbles are sandwiched between crossed cords may be utilized in alternate applications extending well beyond seating furniture typologies. One such alternate application may include visual screens, where the seating surface may be aligned to span vertically to provide a screen or a room divider.
The configuration and arrangement of pebbles, cord(s), and perimeter rim may have a wide range of possible options and the instant description describes but a few of the myriad of potential options. For example, the pebble may alternatively have a wide variety of sizes, shapes and forms, such as those with convex or concave surfaces, textured or configured surfaces, a wide range of perimeter outlines, among others. The channels may be deeper or shallower than the respective cord nested therein, may be aligned or non-aligned with the span of the respective cord nested therein, and may have any imaginable contour, among other qualities and features. Further, the pebble may include any number of channels to receive any number of respective cords. For example, the pebble may include three or more channels to receive three or more respective cords nested therein. Alternatively, the pebble may not include a channel to receive the cord, with the cord simply contacting and/or wrapped against the exterior surface of the pebble.
The cord may be connected to the perimeter rim by a wide variety of alternate means known in industry. For example, the cord may be threaded through vertical holes in the perimeter rim; and/or may be nested in channels of the perimeter rim; and/or may be wrapped around the perimeter rim; and/or may be directly anchored in the perimeter rim.
It is to be understood that the invention is not limited to the illustrations described and shown herein, which are deemed to be merely illustrative of the best modes of carrying out the invention, and which are susceptible of modification of form, size, arrangement of parts and details of operation. The invention rather is intended to encompass all such modifications that are within its spirit and scope as defined by the claims.
