'5 Claims. (Cl. 155106) This invention relates to chairs and pertains particularly to reclining chairs having .a leg rest which moves into position to support the legs as the chair moves into reclining position.
It is an object of the invention to provide a reclining chair of the type described which is extremely simple in construction and which is relatively inexpensive to manufacture.
Other objects and advantages of the invention will appear hereinafter.
A preferred embodiment of the invention selected for purposes of illustration is shown in the accompanying drawings, in which,
Figure l is a side elevation of a chair embodying the invention, one side frame of the chair being broken away, the chair being shown in upright position.
Figure 2 is a similar view showing the chair in reclining position.
Figure 3 is an enlarged perspective view, showing in detail the manner in which the leg rest is connected to the seat, the chair being shown in upright position.
Figure 4 is a section on the line 4-4 of Figure 1.
Figure 5 is a partial side elevation showing a modified form of sliding support for the rear portion of the seat.
Figure 6 is a section on the line 6--6 of Figure 5.
Referring to the drawings, and particularly to Figures 1 to 4 thereof, the chair comprises a base comprising two spaced side frames 1 and 2 which may be rigidly connected together in any suitable manner, as by the connecting frames 3, 3a. The side frames may be of any suitable construction, wood or metal, and may be upholstered or not, as desired.
Located between the side frames 1 and 2 and supported thereon is a reclining seat unit comprising a seat 4 and a backrest 5. The seat and backrest may be of any suitable construction, wood or metal, and may be upholstered or not, as desired. As shown, the seat is of conventional upholstered construction having side frames 6 and 7 and connecting frame 8 supporting upholstered cushion 9. The side frames 6 and 7 extend parallel to the frames 1 and 2 but are spaced inwardly therefrom.
The rear portion of the seat unit is mounted on the side frames for translational, reciprocating movement with respect thereto. Thus, in the form shown in Figures 1 to 4, a pair of tracks 11 are rigidly mounted on the side frames 1 and 2 in position to engage the rollers 33 and 34 mounted on brackets 31 and 32 connected to frames 6 and 7. The tracks 11 are provided with upturned flanges 17 at the ends thereof to limit the translational movement of the seat unit thereon.
The leg rest 21 is also of any suitable construction, either upholstered or not, as desired. In the embodiment illustrated, the leg rest is upholstered and includes side frames 22, to each of which is rigidly secured one of the ends of one of the L-shaped levers 24, the other ends of which are pivotally connected to the actuating links 37. The other ends of links 37 are pivotally connected to the side frames 6 and 7 by pivot pins 38. At points intermediate the ends of the levers 24, they are pivotally connected to the side frames 1 and 2 by means of bolts 28. Thus, the leg rest is mounted on fixed pivots 28 on the side frames, and whenever the seat unit is moved with respect to the base unit, the leg rest, through the actuating links 37, will be caused to swing on the fixed pivots as indicated in Figure 2.
In the upright position of the chair as illustrated in Figure l, the leg rest is in its retracted position beneath the seat. In this position the leg rest is almost entirely concealed by the side frames and the seat, and permits unobstructed access to and from the seat when one is sitting down or arising from the seat. Whenever one sitting in the chair exerts backward pressure against the seat unit, as by pressing forwardly against the side frames, the seat unit will move backwardly on the tracks 11, as indicated in Figure 2. In doing so the backward movement of the seat unit, acting through the links 37, will cause the levers 24 and 25 to swing on their fixed pivots 28 and 29, thus causingthe leg rest to swing to the position shown in Figure 2. In the embodiment illustrated the leg rest swings through an arc of about to to bring the leg rest almost to horizontal position in front of the seat unit in position to support the users legs. If, now, when the chair is thus in reclining position, it is desired to resume upright position, it is only necessary to exert slight downward pressure on the leg rest, accompanied, if desired, by backward pressure against the side frames 1 and 2 to cause the leg rest to swing under the seat.
Brackets 31 and 32 carrying the rollers 33 and 34 which engage the tracks 11 and 12 extend below the tracks and are provided with studs 35 and 36 which engage the under surfaces of the tracks in order to lock the seat unit to the base so that they will not separate if, for example, the chair is lifted by the seat unit.
The seat unit is also connected to the side frames 1 and 2 through links 41 which are pivotally connected to the side frames by bolts 42 and to the seat frames by studs 43 on brackets 44-. If desired, stops 45 and 45a may be secured to the side frames 1 and 2 in position to limit the motion of the links 41.
As shown in Figures 5 and 6, the support for the rear portion of the seat unit may be modified by securing the tracks 4-6 to the seat frames, as shown, and mounting rollers 47 on the side frames of the base. By making the tracks a part of a bracket 48 having a C-shaped flange 4-9 thereon, the seat unit may be locked to the base as previously described.
It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.
I claim as my invention:
1. A reclining chair comprising a base unit having opposed, spaced side frames, a seat unit located between said side frames, means for mounting said seat unit on said base unit for translational movement with respect thereto, aleg rest located between said side frames and mounted on fixed pivots on said side frames, and means connecting said leg rest to said seat unit to cause said leg rest to swing on its fixed pivots as said seat unit moves with respect to said base unit, said means comprising a pair of levers and a pair of actuating links, each of said levers having one end rigidly connected to one side of said leg rest and its other end pivotally connected to one end of one of said actuating links, with the other end of said actuating link pivotally connected to the same side of said seat unit, said links being movable with respect to said seat unit and in which said fixed pivots extend through an intermediate portion of said lever.
2. A reclining chair as claimed in claim 1 in which the pivotal connections of said links to said levers and to said seat unit lie above said fixed pivots and said leg rest lies below said fixed pivots.
3. A reclining chair as claimed in claim 1 in which the pivotal connections of said links to said levers and to said seat unit lie above said fixed pivots and said leg rest lies below said fixed pivots, and in which said leg rest, at one limit of its pivotal movement, is located entirely beneath said seat unit, and at the other limit of its pivotal movement is located in substantially horizontal position in front of said seat unit.
4. A reclining chair as claimed in claim 1 in which said leg rest, at one limit of its pivotal movement, is located entirely beneath said seat unit, and at the other limit of its pivotal movement is located in substantially horizontal position in front of said seat unit.
5. A reclining chair comprising a base unit having opposed, spaced side frames, a seat unit located between said side frames, means for mounting said seat unit on said base unit for translational movement with respect thereto, a leg rest located between said side frames, and
means connecting said leg rest to said seat unit comprising a pair of levers, each of said levers having one end rigidly connected to one side of said leg rest and having an intermediate point pivotally mounted on one of said side frames, and a pair of actuating links, each of said actuating links having one end connected to the other end of one of said levers and the other end pivotally connected to said seat unit, said links being movable with respect to said seat unit.
