Application October 12, ism-serum);-seems 1 Glaim. it (01. 155-416;)

The invention relates to a four point swing suspension device for chairs, swings, or the like.

The primary object of the invention is the provision of a device of this character, wherein the seat in a couch chair or swing can be suspended at four points so that it can have rocking or oscillating motion when occupied, thereby giving comfort to the user and eliminates any mechanical adjustment to enable a change in posture during occupancy by such user while seated.

Another object of the invention is the provision of a device of this character, wherein the assembly thereof can be built into a chair, couch, swing or the like, and enables a swing or rocking motion thereto without excessive exertion on the part of a user of the same.

A further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and eiiicient in operation, strong, durable, readily and easily operated, possessed of few parts, thus economical in repairs, novel in construction, unique in the assembly of the parts thereof, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure l is a side view of a chair, partly broken away, and showing the device constructed in accordance with the invention applied thereto or installed therewith.

Figure 2 is a front elevation of the same.

Figure 3 is a sectional view taken on the line 3--3 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1 looking in the direction of the arrows.

Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure 4 looking in the direction of the arrows.

Figure 6 is a sectional view taken on the line 6-5 of Figure 7 looking in the direction of the arrows.

Figure 7 is a sectional view taken on the line 'I--l' of Figure 6 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A desig- 2 nates generally a couch, involving, a framework forming ahottom orubase ID, a back wall ll, side or end walls 12, and supporting feet or legs 13, respectively, all being united in any suitable manner, and may be of any approved construction.

Within the framework of the couch A is movably arranged a seat section 14, and a back section l5 connected to the latter at its rear by hinges I6 of any selected type. Arranged beneath the seat section I 4 are cross struts H, which are spaced from each other; fore and aft thereof, and extending beyond opposite sides of the same to provide hanger terminals [8. Fitted to these terminals l8 are connecting loops #9 to which are loosely engaged the lower ends of 7 suspension straps 20, these at their upper ends are loosely connected to loops 2| which are fastened in the under faces of the top rails 22 of the side walls 12, so that the seat section M has a four point suspension mounting within the framework of the couch A.

To the side rails 23 of the back section 16 at opposite sides thereof by pivots 24 are connected swinging or drag links 25, only one of the same being shown in Figures 1, 6 and '7' of the drawings, and each link is hinged at 26 to the under face of the top rail 22 next thereto of the side wall l2, so that when the seat section I is moved back and forth the back section I6 rocks therewith. Each link 25 is aft of the four point suspension of the seat section, as will appear in Figure 1 0f the drawings.

Connected to the fore cross strut I! of the seat section [4 is a tensioning spring 21, which is also connected to the frame work at a central location thereof, and this spring counters the forward motion of such seat section in the swinging action of the same.

The four point suspension device, as before described, can be installed within a chair, swing or other like article of furniture, and in the occupancy gives comfort to a user.

What is claimed is:

In a swinging suspension seat, the combination which comprises a pair of spaced parallel substantially rectangular shaped vertically positioned side frames having horizontally disposed upper rails and with the frames connected at the rear, a pair of spaced parallel horizontally disposed forward and rear cross struts positioned above the lower edges of the frames and extended between the said side frames, a seat carried on the said struts, vertically positioned suspension straps extended between the ends of the rear strut and upper rails of the said side frames, inclined suspension straps extended from the ends of the forward strut upwardly and rearwardly to the upper rails of the said side frames, U-shaped loops positioned longitudinally of the seat mounted on the ends of the struts and upper rails of the side frames to which the ends of the said suspension straps are pivotally connected whereby the seat carried by the struts swings with a free movement, said seat having hinge elements extended upwardly atthe rear, a back hinged to the hinge elements of the seat and extended upwardly and rearwardly therefrom, horizontally disposed links positioned between the back of the seat and side frames with the rear, ends of, the

links pivotally connected to the back of the seat and the forward ends thereof pivotally connected to the upper rails of the said side frames, and a JAROME BENSON.
