- a rising seat shown i-a 1 is positioned on a chair 2 the top section of the seat 3 in a raised position being pivoted at itg front end on to the front 5 edge of the bottom section by a hinge pin comprising a round bar lying at least part way across the width of the two sections that preferably comprise two boards of rigid material padded with foam or other suitable filling material and kept in place by a piece of material stretched
- the rising seat 1 is kept firmly fixed to a t chair 2 by a tongue- shaped extension 8 attached to or being part of the bottom section 4 of the rising seat and the extension is
- short spikes 10 may be used that are fixed in the rising seat edge for inserting into * ta ⁇ upholstery of a comfortable chair for example such spikes preferably being made from rigid plastic as shown in FIG or hook and loop
- material may be used fixed to any surface/s of the rising seat and also the chair seat. Ideally the hook and loop material 11 is fixed to a strap 12 fixed to a chair where it can be tucked out of sight. To make the rising seat more stable it may be fixed to the chair or settee in place
- the bottom section of the rising seat shown can be made adjustable by having an adjust ⁇ able frame 13 for example that can be moved outwards into the sides and/ or back of the chair 2 in which it is resting. This adjustment facility that could be effectively utilised in
- a chair that might be otherwise too wide for the rising seat can instead be in the form of knobs 14 screwed into or out of the frame of the bottom section so thAt they can be wedged between the arms of a chair such knobs being attached to threaded bolts that can be screwed into bosses or lugs 15
- FIG 8 shows cushion 1 folded for carrying.
- the top section 3 of the rising seat shown as 1 may be lowered or folded or hinged down on to the bottom
- the hinge pin 5 also acts as a torsion bar that is circular and rests across the ends of either section of the riser seat. Any selected number of torsion springs 17 5. are pla ⁇ ed over the bar that is to say the main body of the spring so ooiled to leave ample room for contraction as weight if applied to the ends of the spring, one leg of each spring coming into contact at . least indirectly with the inner face of the top section and the other leg coming
- torsion spring 20. of the torsion spring is pointing is a cavity 18 of a shape that will allow the leg or legs of the spring to fall as the top section of the r si seat is lowered.
- the spring leg drops into the cavity the spring then has no surface agsinst which it can be pressed to give the spring
- the cavity 18 may be covered on the opposite sur-
- the spring leg can be covered by a dome-shaped cover 19 that can be placed either over the area where the spring leg would otherwise protrude or the whole of the
- top surface of the rising seat as seen can be covered and then upholstered over the hard surface of a larger dome-shaped cover.
- the method of neutralising the effect of the spring can also be used for adjusting the resilience of the top section of the rising seat either by having blind hole cavities of different depths that will decrease the tension of a spring by lengthening the distance between the end of the 5 leg or point of contact of a spring in relation to the top section or by neutralising totally the resilience of a selected number of springs of varying strengths, and posit ⁇ ioning only that spring or springs of a predetermined strength so that it/they become resilient only if its/their
- legs are positioned away from the cavities & onto a firm surface of the board around the said cavities.
- two springs would be used to raise the top section of the rising seat, such springs being joined together by a connecting wire or handle so that springs
- each set can be a different thickness and strength.
- Two sets 21 ⁇ 22 can be
- the board is lowered, the pressure of the board activating the resilience of the spring set 25 selected for the resilience needed to suit the weight of the user; the selection of the springs can either be numerical or by the thickness of the spring/s that could be calibrated to suit
- the spring can instead be located on the torsion bar 5 so that when the torsion bar or hinge pin, if also used as a hinge pin, on which the top section pivots on the bottom section, is moved one way or the ,other, it carries with it at least one
- 35* spring that can, with the two boards opened out and free of the pressure of the spring, lags.in that -opened out position, be located over a cavity, so that when the top section is lowered on to the bottom section no resilience is felt from that spring or set of springs in the cavities. Movement of the springs for adjustment or neutralising the tension can be assisted by small rollers 20 on the spring
- FIGS 10 & 11 legs as jhown in FIGS 10 & 11 if springs are near to boards.
- FIG 13 An alternative method of creating a neutral position that enables the top section to be lowered without resilience from the spring or springs is to move a separate torsion bar 26 on which the springs 17 would be located
- the strengthening of individual torsion springs can be made by raising the spring 17 by locating at least one leg of the spring either directly or perhaps indirectly on a wedgeshaped base 28 that is moveable on the board by ' a screw mechanism 29 that holds the wedge in position under
- the spring leg can be placed in a groove 23 as seen in FIGS 10, 11 and 13 to prevent slippage.
- the top section 3 nay be placed on a hinge 5 - ⁇ C 14 hinge being positioned two to four inches approximately away from the edge of the bottom section, that is to say the front edge, so that when the spring leg 17 5. travels through the cavity 18 the spring leg if in line or forming a large angle with its opposite leg will rest on the end of the bottom section when the top section is lowered freely without re ⁇ ilienoe from the spring, and will not jut out from the front of the 10. risng seat cushion.
- a spindle 3B may be inserted through a hole 39 in the frame and a knob 40 attached to the spindle. As the spindle is turned it drives a board/s 34 & 3 along the grooves 36. Ideally two grooves would be made 20. in the frame, the spindle being positioned between them.
- Attached to the spindle is hook and ' loop material 4 that adhers to hook and loop material 42 on each board, on the top of one board and under the board positioned over the spindle.
- the top board moves to 25. the right when the spindle is turned clockwise and the bottom board moves to the left, each board or an attachment thereto butting up against the inside face of the chair over the seating area thereby wedging the rising seat more firmly in position making it more ⁇ table on the chair.
- a 30. gear in the form of rack and pinion may be used instead of book and loop material. If a spring 44 is incorporated or ela ⁇ tic belting the board carrying the protrusions would be moved inwards against its resilience see FIG 16a Chair is shown as 2.
- Padding shown as 45 can be placed over the end of each board to ensure even pressure on each side of the chair and to protect the fabric cover and at the same height to compensate for the fact that one board will be higher than the other board if two boards are used, and a shaped moulding for example may be fixed to or be part of the board in 5. place of the padding, or spikes could be incorporated.
- the spring 17 may be placing on the torsion bar transversely, and spaced pro-
- trusions or blocks 6 on a sliding section 47 located under spring legs selected by the user or they may be so moved away from the spring legs altogether so that the spring legs are positioned over gaps between the blocks so that when the top section is lowered on to the bottom section
- the blocks & gaps may be incorporated on a fixed section and the spring legs placed on to the blocks or over the gaps between the
- section 3 can be lowered on to the bottom section *
- the gaps may be formed from cut-outs in a solid block that may be fixed to the inside face of one of the sections that is to say the top or bottom section or may be located to slide on one of the sections for positioning
