10 Claims. (Cl. 155-106) This invention relates to articles of furniture and more particularly to articles of repose for supporting the body of a person, wherein a back-reset, seat and leg-rest are movable in a predetermined relationship relative to a support.
An object of the invention is to provide an article of repose of above described type with an advantageous mechanism for controlling the movements of the legrest in dependence on movements of the back-rest.
Another object of the invention is to improve on the construction of articles of repose as now ordinarily made.
Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanying drawings forming part of this specification, wherein:
Fig. 1 is a side elevational view of a reclining armchair according to the invention, a portion of a side wall being broken away,
Fig. 2 is a side elevational view of the reclining armchair of Fig. 1, wherein however the movable members of the chair are in a reclined position, 1
Fig. 3 is a side elevational view of another embodiment of an armchair according to the invention, a portion of a side wall being broken away,
Fig. 4 is a side elevational view of the armchair of Fig. 3, wherein however the movable members of the chair are in the reclined position,
Fig. 5 is a side elevationalview of a further embodiment of an armchair according to the invention, a portion of a side wall being broken away,
Fig. 6 is a side elevational view of the armchair of Fig. 5, wherein however the movable members of the chair are in the reclined position,
Fig. 7 is a side elevational view of still another embodiment of an armchair according to the invention, a portion of a side wall being broken away, and
Fig. 8 is a side elevational view of the armchair of Fig. 7, wherein however the movable members of the chair are in the reclined position.
Referring now to Figs. 1 and 2, 10 generally indicates a support having side walls 12 and 14 connected with each other in any suitable way.
A back-rest 16 and a seat 18 are swingably mounted on said support 10 at 20. The upper end of a first link or guiding link 22 is swingably mounted on a transverse rod 24 mounted on the support 10. The upper end of a second link or guiding link 26 is swingably mounted on a transverse rod 28 carried by the support 10. A bent bar 30 is pivoted to the lower ends of said links 22 and 26 at 32 and 34 respectively. The upper end of said bent bar 30 is rigidly connected with a board 36 extending across the chair. Said bent bar 30 and the board 36 rigid therewith form a third link or controlling link generally indicated by 38 of a linkage to be described hereinafter. The bent bar 30, the first link 22 States Patent 0 2,788,058 Fatented Apr. 9, 1957 and the second link 26 are arranged substantially in the center of the chair.
The upper end of another link or arm 40 (in some of the claims referred to as fifth link) is pivotally connected with the seat 18 at 42. Said link 40 having a slot 44 slidably engaged with a pivot 46 arranged on the link 38. The lower end of the link 40 is pivoted at 48 to one end of a link or bar 50 (in some of the claims referred to as fourth link), the other end of which is pivoted to an intermediate point of a leg-rest 52 at 54. The upper end of the leg-rest 52 is pivoted at 56 to the cross board 36 of the link 38.
The movements of the linkage 22, 26, 38, 40, 50, 52 described above are controlled in dependence on the movements of the back-rest 16 by means of a connecting link 58 pivoted to a lower extension of the back-rest 16 at 60 and to an intermediate point of the link 26 at 62.
On each side of the chair another connecting link 64 (only one being shown) is pivoted to a lug 66 of the cross board 36 at 68 and to the seat 18 at 70. The pivot 70 is well above the lower surface of the seat 18.
The connecting link 64 controls the movements of the seat 18 in dependence on the movements of the linkage 22, 26, 38, 40, 50, 52 and thus through the connecting link 58 in dependence on the movements of the back-rest 16. Y
Fig. 1 illustrates the movable members of the chair in the sitting position. Upon a rocking of the back-rest 16 about its pivot 20 the movable members of the chair are brought into the position shown in Fig. 2 by means of the linkage described above. In said reclined position of Fig. 2 the cross board 36 being propelled forwardly covers the space between the front end of the seat and the rear end of the leg-rest created by the forward propelling of the leg-rest.
Fig. 3 illustrates the sitting position of the movablemembers of the chair while Fig. 4 i1lustrates the extreme reclined position thereof.
According to the embodiment of a reclining armchair shown in Figs. 5 and 6, again the mechanism of the chair is substantially the same as that of the chair shown in Figs. 1 and 2. However according to Figs. 5 and 6 the second link 226 has a rearward extension 274 rigid therewith and the connecting link 258 being pivoted to the back-rest 216 at 260 is pivoted to said extension 274 of the link 226 at 276.
Fig. 5 illustrates the sitting position of the movable members of the chair and Fig. 6 illustrates the movable members of the chair in the extreme reclined position.
The embodiment of an armchair shown in Figs. 7 and 8 is with respect to its mechanism substantially similar to that shown in Figs. 1 and 2. However according to Figs. 7 and 8 the connecting link 364' is pivoted to the seat 318 at 370 at a point near to the lower surface of the seat 318. The other end of said connecting link 364 is pivoted at 378 to a bracket 380 arranged on the bar 330 forming a portion of the link 338.
The low arrangement of the pivot 370 eliminates damage to the upholstery by the connecting link 364 during relative movements by the said link and the seat.
Fig. 7 illustrates the movable members of the chair in the sitting position while Fig. 8 illustrates said members in the extreme reclined position.
Preferred embodiments of the invention have been described, but it is understood that this disclosure is for the purpose of illustration and that various changes in shape and proportion of parts, as well as the substitution of equivalent elements for those herein shown and de scribed may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
Suitable stops for limiting the sitting and extreme reclined positions may be provided on the chair and/or locking means may be arranged for holding the movable members of the chair in any desired position.
