Abstract
ABSTRACT
The following specification discloses:
a reclining chair having a seat and backrest attached and forwardly moveable together with relation to the chair frame into an upright or a reclining posture. Each side of the frame has a lever action mechanism pivotable attached between the chair frame and the seat. A forward lever of the action is of greater length than a rearward lever and each lever inclines slightly backwards when said chair is in the upright position and inclines substantially forwardly when the chair is in the reclining position thereby allowing the backrest and seat to be moved forward and outward without any backward movement thereby allowing the chair to rest against a wall in either position.

Description
4~3 :
BACKGROUND OF THE INVENTION
The present invention relates to reclining chairs moveable into upright or reclining positions. In particular the invention relates to reclining chairs wherein the seat is attached to a frame where both sides of the chair are provided with a linkage mechanism to raise a foot rest member with the movement of the seat.
The conventional recliner chair has the two normal positions: (1) a sitting position and (2) a reclining position. The back rest of the chair in the sitting position is in a more upright position than it is in the so-called reclining position, while in the reclining posit-ion the back moves backwards and lower than in the sitting position.
There is the known disadvantage in the above chairs in that when they are changed into the reclining position from the sitting position, the back rest swings backwards and creates a heavy imbal-ance point. Since it is known that the mechanisms used have wide overloading characteristics backwards, the chair will have a tend-ency to tip over.
Another disadvantage of known chairs is that they require relative-ly more space for construction depth than the usual armchair.
With the conventional type of recliner chair, the back of the chair should not be placed against the wall in the upright position since the back rest moves backward when the whole chair is reclined. The chair must be moved away from the wall leaving sufficient space for the back of the chair to swing backwards to effect changing the chair from the sitting position to the reclining position.
It is therefore an object of the present invention to provide a reclining chair which alleviates the beforementioned disadvantages.

An extension arm 15 is provided link 37 above the pivot point 10 and a bar 16 is pivotably attached to the upper end of arm 15. The bar 16 extends to the front of the chair 31. By means of the known scissor action, designated numeral 17 in the drawings, lever bar 16 is connected for a cranking action between arm 15 and a footrest 18.
Forward movement of lever 37 pushes out the footrest 18 and backward movement of lever 37 pulls the footrest into storage beneath the chair seat as shown.
When the chair 31 is pushed forward, by either external forces or by means of the occupant pulling on the armrests while seated in the chair, while simultaneously pushing with his butt against seat 35 and back 36, links 37 and 38 will be cranked into the positions of fig.
2 and 4, to provide a reclining mode for the chair, with link 37 resting and held against further forward movement by stop 1~.
During the above action the footrest 18 will swing out to its -upwardly facing position.
The footrest could also be used to put the device in reclining mode by a pull force exerted externally on it.
If there are no armrests extending upward of the frame on which an occupant can exert a pull or push force to change the mode of the chair he can change the mode merely by the force-push of his body on the seat and back members 35,36, with if necessary a push from his feet on the floor.
A lightweight occupant or child may not be able to counterbalance the chair to change its mode while being an occupant therein, therefore, a textile belt or the like can be attached to either side of the seat to assist the occupant to exert the upsetting force to change the mode.
An alternative type of backrest is shown in figure 3 and 4 where a fixed headrest 20 is provided with the frame armrest part being carried upward to connect with it (dotted line 22) to give a stable and immoveable posture to the rear of the chair where it sits against a wall.
- 1~'1 3~
When the chair o~ figures 3 and 4 is reclined as shown in fig.4 a gap is created between the headrest 20 and the back 36. To cover the gap a textile cover 21 is attached over it to be tight as in ~;
fig. 4 in the reclining position and folding into the gap in the sitting position as shown in fig. 3.
MODE OF OPERATION
As discussed above, the chair can be operated by an occupant with-out the necessity of using external forces levers handles or other means provided his weight-mass is adequate to counterbalance the locking action of the link mechanisms which are either forwardly locked or rearwardly locked by the stops 19,14 respectively. The unsubstantial rearward inclination of levers 37,38 hold the chair in the sitting position until the occupant merely shifts his weight to push the seat up and pull the back down. When settled in the reclin-ing position the seat is unable to be easily reverted to sitting pos-ition until the occupant either uses his weight to counterbalance it backwardly or pulls on the arms to effect the shift of forces, because of the over-centre lock required and created by the links 37,38. The degree of overcentre locking of the rear link is seen to be very small since the mass weight of the occupant is greatest there where the upward movement of the link 37 is most easily resisted ( to retain the position) or most easily effected (by shifting weight to change position).
By having the chair only move forwardly of the frame when in use and with relation to a fixed position of the frame, the chair of the invention can be set substantially against a wall, where desired, unlike the known chairs requiring a space behind ~or manoeuvring.
During the above action the footrest 18 will swing out to its -upwardly facing position.
The footrest could also be used to put the device in reclining mode by a pull force exerted externally on it.
If there are no armrests extending upward of the frame on which an occupant can exert a pull or push force to change the mode of the chair he can change the mode merely by the force-push of his body on the seat and back members 35,36, with if necessary a push from his feet on the floor.
A lightweight occupant or child may not be able to counterbalance the chair to change its mode while being an occupant therein, therefore, a textile belt or the like can be attached to either side of the seat to assist the occupant to exert the upsetting force to change the mode.
An alternative type of backrest is shown in figure 3 and 4 where a fixed headrest 20 is provided with the frame armrest part being carried upward to connect with it (dotted line 22) to give a stable and immoveable posture to the rear of the chair where it sits against a wall.
- 1~'1 3~
When the chair o~ figures 3 and 4 is reclined as shown in fig.4 a gap is created between the headrest 20 and the back 36. To cover the gap a textile cover 21 is attached over it to be tight as in ~;
fig. 4 in the reclining position and folding into the gap in the sitting position as shown in fig. 3.
MODE OF OPERATION
As discussed above, the chair can be operated by an occupant with-out the necessity of using external forces levers handles or other means provided his weight-mass is adequate to counterbalance the locking action of the link mechanisms which are either forwardly locked or rearwardly locked by the stops 19,14 respectively. The unsubstantial rearward inclination of levers 37,38 hold the chair in the sitting position until the occupant merely shifts his weight to push the seat up and pull the back down. When settled in the reclin-ing position the seat is unable to be easily reverted to sitting pos-ition until the occupant either uses his weight to counterbalance it backwardly or pulls on the arms to effect the shift of forces, because of the over-centre lock required and created by the links 37,38. The degree of overcentre locking of the rear link is seen to be very small since the mass weight of the occupant is greatest there where the upward movement of the link 37 is most easily resisted ( to retain the position) or most easily effected (by shifting weight to change position).
By having the chair only move forwardly of the frame when in use and with relation to a fixed position of the frame, the chair of the invention can be set substantially against a wall, where desired, unlike the known chairs requiring a space behind ~or manoeuvring.
