Abstract:
A customizable multiple adjustment and multiple position seating apparatus or chair with independently adjustable front and rear seat height or elevation and front to rear seat slope; adjustable seat length or distance from the front of the seat to the rise of the backrest; and 180° pivoting/reclining backrest. Height of the front of the seat is adjustable from flat near the ground to armrest elevation. The rear of the seat, independent from front adjustments, is adjustable from near ground level to just below armrest level. Independent adjustability allows the seat to be positioned at multiple elevations and incline angles. Numerous backrest recline angle settings are obtainable throughout the 180° pivotability as well as numerous seat lengths. The backrest pivots to a forward position to become a handle for wheelbarrow-like mobility and the apparatus can be further rotated vertically and rested on the backend for a smaller storage profile.

Description:
BACKGROUND 
       [0001]    Numerous types, styles, and configurations of seating apparatuses or chairs are known in the prior art, including many variations of adjustable components. Adjustability in the prior art focuses mostly on reclinable backrests, foldability, or adjustable leg length. The much sought-after adjustability is intended to create a chair with improved customizability and increased comfort. For maximum comfort and customizability for the broadest range of users, a seating apparatus is needed that is significantly adjustable on multiple planes and axes including both the seat and backrest. A seating apparatus or chair is needed with adjustable seat slope, adjustable seat height, adjustable backrest reclinability, and adjustable distance between the front of the seat and the backrest junction. 
       SUMMARY 
       [0002]    One embodiment of the multi-adjustable multi-position seating apparatus includes a frame, an adjustable multi-position seat, and an adjustable multi-position backrest. 
         [0003]    The seat is slidably and pivotally mounted within the frame in both the front and rear of the seat. The front of the seat can be adjusted to numerous elevations from the bottom of the frame to the top. The rear of the seat can also be adjusted to numerous elevations from the bottom of the frame to nearly the top. The slope of the seat, the drop from front to rear, can be adjusted from a steep Adirondack chair style incline to a level position or even a decline from rear to front. 
         [0004]    The backrest is slidably and pivotally mounted at its bottom to and above the seat while the upper reclinable adjustability is secured by a slidable mechanism along the vertical length of the backrest and selectable notches along the top of the frame. The distance between the front of the seat to the point where the backrest rises vertically away from the seat can be slidably adjusted forward or backward to comfortably fit the length of a user&#39;s legs. The backrest can also be positioned in multiple vertical or reclined angles by selecting the desired position and sliding the reclining adjustment mechanism into the corresponding notch along the top of the frame. 
         [0005]    In one aspect of the chair, adjustment and subsequent stabilization of the front and back of the seat and the bottom of the backrest is accomplished with adjustment guide-latch-pivot assemblies slidably engaged on guide bars. Stabilization is achieved by spring-loaded pin latches on the guide-latch-pivots mounted on the guide bars which contain multiple holes along the length. An engaged latch is disengaged by pulling on the pin and compressing the spring retracting the pin from the hole, then adjustment is made by sliding the guide-latch-pivot along the guide bar. When the preferred position is reached, the pin is released and the spring causes the pin to enter the corresponding bore in the bar. The front and rear of the seat and the bottom of the backrest are pivotally connected to the guide-latch-pivots by rods inserted into tube-like connections which facilitate easy incline changes during height adjustments. 
         [0006]    For moving, transport, or storage, the apparatus can be adjusted to the lower settings on both the front and rear, the reclining adjustment mechanism disengaged from the top of the frame, and the backrest rotated all the way forward until it contacts the seat near the ground in a mostly flat position along the ground or surface. The reclining adjustment mechanism engages stops on the front of the frame and the top of the backrest then is used as a handle to raise the front of the frame whereby wheels located on the back of the frame come in contact with the ground or surface in a wheelbarrow-like configuration. The front of the chair can be raised further until the frame is rotated into a fully vertical position where it is rested on frame mounted propstands and the wheels in a mostly level vertical position. 
       Advantages 
       [0007]    Accordingly, several advantages of one or more aspects are to provide a seating apparatus or chair with the adjustability to be customized to fit almost any person of most any size, that allows the seat height and slope to be adjusted to fit most any sitter&#39;s desired comfort position, that allows the backrest to be adjusted to change the seat length to fit the sitter&#39;s leg length, that the backrest reclining angle can be adjusted to numerous desired angles, and that allows the chair to be easily moved or stored in an upright position. 
         [0008]    Advantages include:
       Front of seat is adjustable up and down;   Rear of seat is adjustable up and down;   Entire seat height is adjustable up and down while also maintaining the same slope orientation;   Seat slope is adjustable from a steep Adirondack chair style slope with rear of seat near ground level and front of seat at normal comfortable height to a flat orientation or even a decline from rear to front;   Entire backrest is adjustable forward or backward shortening or lengthening the length of the seat or the distance between the front of the seat and the point where the backrest rises vertically away from the seat;   Vertical angle or recline angle of the backrest is pivotal and adjustable of a 180° radius from a horizontal state or lounge-chair-like rearwardly recline to a forward position parallel to the angle of the seat, even a flat state at near ground level;   Backrest pivotally transforms to a wheelbarrow-like handle for lifting the front of the seating apparatus in order to engage the rear facing wheels to the ground or surface for rolling or transport.   Seat and backrest both adjust to a forward position in order to facilitate rotating the front of the seating apparatus upward 90° and onto its rear end to accommodate a smaller profile storage posture;   Every conceivable adjustability a chair can possess on the two basic elements of a chair, the seat and the backrest, is disclosed in one embodiment of the seating apparatus.

       Operation 
       [0160]    Referring to  FIGS. 1 ,  4 ,  5 ,  6 ,  8 , and  9 , operation of one embodiment of a multi-adjustable multi-position seating apparatus is as follows: 
         [0161]    To adjust the front of seat  50  height, user simultaneously pulls on rings  43 - 4  and  45 - 4  retracting pin plungers  43 - 2  and  45 - 2  from holes in guidebars  26  and  28 . Guide-latch-pivots  42  and  44  are then free to move up or down guidebars  26  and  28 . User moves front of seat to desired location, releases rings  43 - 2  and  45 - 2  allowing pin plungers  43 - 2  and  45 - 2  to enter corresponding holes in guidebars  26  and  28  thereby stabilizing front of seat  50  height location. 
         [0162]    To adjust the rear of seat  50  height, user pulls on rings  47 - 4  and  49 - 4  retracting pin plungers  47 - 2  and  49 - 2  from holes in guidebars  38  and  40 . Guide-latch-pivots  46  and  48  are then free to move up or down guidebars  38  and  40 . User moves back of seat to desired location, releases rings  47 - 4  and  49 - 4  allowing pin plungers  47 - 2  and  49 - 2  to enter corresponding holes in guidebars  38  and  40  thereby stabilizing rear of seat  50  height location. 
         [0163]    To adjust the front/rear location of the bottom of backrest  100 , or the distance from the front of seat  50  to the bottom of backrest  100 , user pulls on rings  91 - 4  and  93 - 4  retracting pin plungers  91 - 2  and  93 - 2  from bores in guidebars  86  and  88 . Guide-latch-pivots  90  and  92  are then free to move forward or backward on guidebars  86  and  88 . User moves bottom of backrest to desired location, releases rings  91 - 4  and  93 - 4  allowing pin plungers  91 - 2  and  93 - 2  to enter corresponding holes in bars  86  and  88  thereby stabilizing the bottom of backrest  100 . 
         [0164]    To adjust the reclining angle of backrest  100 , slide  104  is pulled upward raising rod  104 - 1  clear of notched-rail-bars  20 - 20  and  20 - 21 . Backrest is moved to desired angle and slide  104  is released to allow rod  104 - 1  to rest against the corresponding lug or figure on notched-rail-bars  20 - 20  and  20 - 21 . 
         [0165]    To transport, both front and rear of seat  50  are placed in the lower settings using the above described method, then slide  104  is pulled upward sufficiently to allow backrest  100  to be rotated forward until it is parallel to seat  50 . Slide  104  is moved to allow rod  104 - 1  to rest under and against catches  20 - 2  and  20 - 4 . Handle  100 - 3  is lifted thereby lifting the front of the apparatus off of the surface or ground leaving only wheels  20 - 9  and  20 - 11  in contact with the surface or ground resulting in the seating apparatus taking on a wheelbarrow-like orientation. The handle can continue to be raised higher tilting the apparatus over onto the rear until propstands  20 - 7 - and  20 - 8  contact the surface or ground and the apparatus will be in a stabilized vertical position. 
         [0166]      FIG. 4  shows the routes of travel of all of the moveable, adjustable, pivotable components of one embodiment of a multi-adjustable multi-position seating apparatus. The front of seat  50  pivots centered off of the rear mounting rod  50 - 3  and guide-latch-pivots  46  and  48 . The rear of seat  50  pivots centered off of the front mounting rod  50 - 2  and guide-latch-pivots  42  and  44 . Seat  50  can travel in a straight up or down direction by releasing guide-latch-pivots  42 ,  44 ,  46 , and  48  simultaneously. Guidebars  26  and  28  pivot in a rearward or frontward direction depending on the incline of seat  50 . The orientation of seat  50  shows guidebars  26  and  28  pivoted a few degrees off of 90° vertical. The bottom of backrest  100  moves in a forward or backward direction along guidebars  86  and  88 . The top of backrest  100  can travel a radius of almost 180° from a step recline toward the back to horizontal parallel to seat  50 . 
       ALTERNATIVE EMBODIMENTS 
       [0167]    While the above description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of one embodiment. Many other variations and modifications are possible. 
         [0168]    For example, the structural material that the apparatus is constructed of could be any number of shapes, styles, or configurations. Similarly, the material that the apparatus is constructed of could be any number of materials such as carbon steel, stainless steel, aluminum, plastic, wood, etc. While the drawings appear to show the seating apparatus as likely an outdoor chair, the apparatus could be covered or configured as indoor furniture. 
         [0169]    Additional alternative embodiments include: The size of the apparatus or any or all of the components could be increased or decreased. The apparatus could be configured as a flat lounge type chair with a longer seat and/or an alternative mounting structure at the bottom of the backrest and/or back of the seat configuration. One or more of the adjustability capabilities could be eliminated. One or more of the pivot points could be eliminated, for example the bottom of the backrest pivot point or the rear of the seat pivot point. The notched-rail-bars could be configured or constructed any number of ways and configurations of fingers, slots, cut-outs, etc. 
         [0170]    While the drawings show dual points of adjustment at each fulcrum, the apparatus could be configured to have a single or multiple adjustment devices to adjust any of the fulcrums. The apparatus could be configured for adjustability while the user is seated. The pivoting configuration could be accomplished using bearings instead of rods and sleeves. Bearings could be applied to aid any of the sliding components. The apparatus could be configured as a glider or swing with the addition of glider or swing accessories. The seat height adjustments could be accomplished via other means including screws with threaded guides, ratchets with grooved bars, mechanisms similar to traditional bumper jacks, electric motors, etc. The backrest reclining angle could be stabilized with any number of alternative mechanisms or configurations, many can be learned in a search of the prior art. The ornamental or aesthetic design of the apparatus could be configured in any number of styles or designs. Any number of mechanical, stylistic, ornamental, or other add-ons could be added to the apparatus. The seat, backrest, and armrest coverings or surfacing could be any number of alternative materials or substances. 
         [0171]    With respect to the above numerous possible alternative embodiments, it is obvious that numerous modifications, omissions, substitutions, arrangements, and changes could become obvious to those skilled in the art; therefore, the seating apparatus cannot be limited to the exact embodiment, description, configuration, construction, or operation shown. 
       CONCLUSION, RAMIFICATIONS, AND SCOPE 
       [0172]    The foregoing is considered an illustration of the principles of one embodiment of a multi-adjustable multi-position seating apparatus or chair with an independently adjustable and customizable seat height and incline along with a fully adjustable seat length and backrest reclining angle. At least one embodiment offers a seating apparatus or chair with the adjustability to be customized to fit almost any person of most any size, that allows the seat height and slope to be adjusted to fit most any sitter&#39;s desired comfort position, that allows the backrest to be adjusted to change the seat length to fit the leg length and reclining angle desired, and that allows the chair to be easily moved or stored in an upright position. 
         [0173]    It is obvious that many variations, changes, and modifications are possible without departing from the scope of the apparatus. Accordingly, the scope should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
