Foam pads 105, 106, fabric 101, and working fabric 108 are secured between button head 107H and flange 107F. Pawl 107P engages teeth/ridges 107R on the shaft 107 and prevents rightward extraction of button head 107H when viewing FIG. 1A. Stop 107S limits the depth of insertion of the shaft 107 into flange 107F.

(21) FIG. 1D is a schematic cross-sectional view 100D of upper wooden support 111U, lower wooden support 111L, staples 111J affixed to the upper wooden support 111U and the lower wooden support 111L, string 107W affixed by the staples 111J to the upper wooden support 111U and lower wooden support 111L. FIG. 1D also illustrates frame member 112. FIG. 1E is a schematic cross-sectional view 100E similar to FIG. 1A shown with the structure of FIG. 1D. FIG. 1E illustrates string 107W restraining flange 107F against rightward movement and securing the flange with respect to the chair frame member 112 and the upper wooden support 111U and the lower wooden support 111L.

(22) FIG. 1B is a cross-sectional view 100B taken along the lines 1B-1B of FIG. 1. FIG. 1C is a perspective view 100C of a portion of the chair structure illustrating upper wooden supports 111U and lower wooden supports 111L FIG. 1B illustrates backing fabric 108 and several flanges 107F. Each flange 107F includes openings 107Z in button locking member 107F and thread holes 107T. Openings 107Z include walls 107Y which allow easy insertion of string 107W into thread holes 107T. Openings 107Z communicate with thread holes 107T. Holes 107T are used to secure string 107W as illustrated in FIGS. 1C, 1D and 1E. Shapes other than holes may be used to secure strings 107W. Strings 107W position the flanges 107W and the tufts 104 as desired and secure the button head 107H, the shaft 107, and the flange 107F with respect to the frame members 112, 111U, and 111L. Optionally, springs may be added in strategic locations of the chair structure.

(23) Pawl housing 107K is shaped to allow pad 107P room to move in response to the incoming ridges 107R of the ratchet portion of the shaft 107. Rail 107L is illustrated in FIGS. 3 and 3A.

(24) FIG. 3 is a perspective view 300 of the button head 107H and the shaft 107 extending therefrom. Depressions 107D are illustrated in FIG. 3 and they enable better gripping of the shaft 107 as it is pulled through passageway 121 shown in FIG. 1A. FIG. 3A is a perspective view 300A of the button head 107H and the shaft 107 extending therefrom.

(25) The insertion depth of the button head 107H is controlled by protrusion 107S on shaft 107. As shaft 107 is inserted in flange 107F, the insertion continues until protrusion 107S engages backing fabric 108 and flange 107F. Then string 107W is installed in and through openings 107Z and thread holes 107T in the flange. String 107W is then secured by staples 111J as illustrated in FIGS. 1D and 1E and tension is applied as required. FIG. 1F is a skeleton schematic view without the pads/cushions 105, 106 shown.

(26) As the ridges 107R of the shaft enter the pawl housing 107K, pawl 107P moves into gap 107G to allow clearance of the ridges 107R. Pressure is applied to the head portion 107H as the ridges 107R of the shaft 107 are inserted into the pawl 107P. It is necessary to apply pressure to the button head 107H because the foam pads/cushions 105, 106 are compressed by the button head 107H and the flange 107F thereby offering some resistance to the insertion of the shaft 107 into the pawl. Preferably the flange 107F, the centrally located pawl housing 107K and the pawl 107P are made of plastic. Alternatively, the flange 107F, the pawl housing 107K and the pawl could be made of metal. Similarly, the shaft 107 and the ratchet portion of the shaft having ridges 107R could also be made of metal.

(27) FIG. 3B is a top view 300B of the button head 107H and the shaft 107 extending therefrom. FIG. 3C is an end view 300C of the button head 107H and the shaft 107 extending therefrom. FIG. 3D is a cross sectional view 300D taken along the lines 3D-3D of FIG. 3B. Button head 107H may be of any color.

(28) Alternatively, a cap 180 may be placed over the plastic head 107H. Cap 180 may have a fabric cover 101 secured to the cap and the fabric cover may match the fabric used over the chair/furniture. Fabric cover 101 may be affixed to the cap 180 by a variety of means including by adhesive means or by cinching the fabric cover 101 to the cap 180. Cap 180 may be adhered to the head 107H through adhesive means. Alternatively, cap 180 may include first groove 181, second groove 182, and third groove 183 which interfit with first tapered ridge 351, second tapered ridge 352, and third tapered ridge 353, respectively, of the plastic head 107H. Thus the cap 180 and head 107H are secured together as illustrated in FIGS. 3E and 3F. FIG. 3E is a cross-sectional view 300E of the cap 180 with fabric 101 thereover which is attached to the button head 107H. Also see, FIGS. 1A and 1E which illustrate cap 180 and fabric cover 101 residing over the button head 107H.

(29) FIGS. 1A and 1E illustrate cap 180 and fabric cover 101 residing over the button head 107H.

(30) Referring to FIGS. 1E, 2D and 3D, ridges 107R reside on both the upper and lower sides of the shaft 107 enabling easy insertion of shaft 107 into the locking member without regard to orientation of the shaft before inserting the shaft into pawl 107P.

(31) FIG. 2 is a perspective view 200 of the button locking member 107F. Channel 107C is illustrated in FIG. 2.
