CHAIR WITH A CURVILINEAR FRAME

Abstract

A chair with a curvilinear frame includes two vertically aligned curvilinear tubular side frame members facing each other, a horizontally aligned seat attached to each side frame members by two screws inserted through side member screw hole in each side member and into seat screw holes said seat's right side and left side, and a generally vertically aligned back attached to each side frame members by two screws inserted through side member screw hole in each side member and into back screw holes said back's right side and left side.

Claims

1. A chair with a curvilinear frame comprising: a. two vertically aligned curvilinear tubular side frame members, b. a horizontally aligned seat attached to each side frame members by two screws inserted through side member screw holes in each side member and into seat screw holes said seat's right side and left side, and c. a generally vertically aligned back attached to each side frame members by two screws inserted through side member screw hole in each side member and into back screw holes said back's right side and left side.

2. The chair according to claim 1 where said side frame members are comprised of high strength aluminum tubing.

3. The chair according to claim 1 wherein the two curvilinear tubular side frame members are facing each other.

DETAILED DESCRIPTION

Description—Preferred Embodiment

[0045] FIG. 1 shows a perspective view of the preferred embodiment of the present invention. Side frames 10 are attached to back 30 by screws 40 in side frame screw holes 1I and to seat 20 by seat screw holes 21. For clarity side frame screw holes 11 and seat screw holes 21 are omitted from the embodiment of FIG. 21. Side frames 10 each include an arm section 101, back section 102, leg section 103, and base section 104, all of which are curved. FIG. 2 is a left-side perspective of the present invention. FIG. 3 is top plan view of the present invention. FIG. 4 is a bottom plan of the present invention. FIG. 5 is a front elevation view of the present invention. FIG. 6 is a rear elevation view of the present invention. FIG. 7 is a cross-sectional view of the chair with a curvilinear frame taken along line 1-1 in FIG. 1. FIG. 8 is a cross-sectional view of the chair with a curvilinear frame taken along line 2-2 in FIG. 1.

[0046] Key Points:

(1) Preferred material is high strength aluminum freedom tubing formed by a single-stroke tube-bending technology. Other construction materials possible.
(2) Lightweight, flexible, strong, seating parts. Interchangeable with back.
(3) Seating and back material: bespoke weave, produced with 3D CNC knitting technology—breathable. Long-lasting seating support.
(4) Two component parts. Extreme simplicity. Easy to store, ship. Interchangeability means fewer supply-chain problems.
(5) Side-frame members similarly configured.
(6) Seat and back members identically configured and interchangeable.
(7) Unique configuration of side frame members allows for upward or downward movement of the seat while maintaining the same arm/seat relationship regardless of back or seat movement.
(8) Single-stroke forming process allows for a transition from small to large radius bends without the need for any straight section or runs.
(9) Curvilinear sections—continuously curving—no straight sections—no angular bends.
(10) Delivers comfort and adapts to the user's movements as the seat and back flex.
(11) The use of aluminum side support frames (e.g., side frames 10) provides aesthetic beauty in a lightweight minimalist design.

Operation—Preferred Embodiment

[0047] A user may sit on seat 20 and enjoy freedom of movement in all direction as side frames 10 move with the user.

Conclusion, Ramifications, and Scope

[0048] The present invention as described herein has been designed to address the problems found in the prior art. Accordingly, the objects and advantages of the present invention are: [0049] (1) To provide a chair having only two one-piece tubular frame elements. To provide a chair having only two one-piece tubular frame elements that have no linear (straight-line) runs. [0050] (2) To provide a chair having only two one-piece tubular frame elements with curvilinear runs. [0051] (3) To provide a chair that can be easily disassembled and shipped as four separate parts (two side frame members and two interchangeable seat/back elements. [0052] (4) To provide a chair having a seat cushion and a back cushion that are identical parts and thereby interchangeable, less expensive to manufacture, and easier to store or ship. [0053] (5) To provide a chair with side/back frames that are identical parts and thereby interchangeable, less expensive to manufacture, and easier to store or ship. [0054] (6) To provide a chair that allows the back to move independently of the seat without the use of additional springs or mechanical devices. [0055] (7) To provide a chair that allows the user to safely move in three dimensions while changing position or simply rocking the chair. This includes leaning backwards or forward, rocking backwards or forward, twisting from side-to-side, and flexing the seat upwards or downward.
