Description

Jan. 3, 1967 M. PEARLSTINE FURNI TURE Filed Feb. 14, 1964 INVENTOR. MORTON PEARLST/NE ATTORNEY United States Patent 3,295,590 FURNITURE Morton Pearlstine, Bala-Cynwyd, Pa., assignor to Bunting Company, Inc., Philadelphia, Pa., a corporation of Pennsylvania Filed Feb. 14, 1964, Ser. No. 344,925 6 Claims. (Cl. 160-327) This invention relates to an article of furniture. More particularly it relates to an article of furniture, although made of materials other than fabric, is constructed to give the feel of fabric when in use.

It is often desirable to construct the seat and back portion of furniture from material other than fa'bric. Materials such as metal and plastic have the advantages of being more durable and easier to maintain. This is particularly important in outdoor furniture which may be exposed to the weather. Heretofore, while such materials have been used to overcome the disadvantages of fabric, they have failed to duplicate the feel and inherent comfort of fabric.

It has been found that furniture can be constructed using materials other than fabric, and yet such furniture will have the feel and inherent comfort of fabric. Thus, the present invention overcomes the major disadvantage of the prior art. The present invention solves the problem of prior art by providing flexible slat members, shaped and attached to the furniture frame in a novel manner. In particular, each flexible slat member is shaped and fastened to its supporting frame in such a manner that, except for its side edges and the point where it is fastened, it stands away from the frame when no load is applied to it. When, however, a load is applied to it, such as a person sitting on the furniture, it gives and bends around the frame. The result is that the person using the furniture is given the feeling that he would have if the material were fa'bric.

It is an object of this invention to provide a novel article of furniture.

It is another object of this invention to provide a novel article of furniture using materials other than fabric yet giving the feel of fabric to the user.

It is yet another object of this invention to provide an article of furniture constructed in a novel manner of materials other than fabric, yet retaining the feel and inherent comfort of fabric.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 1 is a perspective view of a chair constructed in accordance with this invention.

FIGURE 2 is a cross sectional view taken along the line 22 of FIGURE 1, showing a slat in its unloaded position.

FIGURE 3 is the same as FIGURE 2, showing the slat in its loaded position.

FIGURE 4 is a view taken along the line 4-4 of FIG- URE 1, showing the slat in its unloaded position.

Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIGURE 1 a chair generally designated as 10. Although chair has been chosen as the embodiment in which to describe the invention, it is obvious that the invention is not limited to this specific embodiment.

The chair shown in FIGURE 1 is collapsible. It comprises

legs

12, 14, 16 and 18,

arms

20 and 22, seat frame 24, and back frame 26.

Legs

12 and 14 are formed from a continuous piece of tubing bent in a U-shape. Legs 3,295,590 Patented Jan. 3, 1967 16 and 18 are fonmed in the same manner. Leg 14 is pivotably joined to leg 16 and arm 22 by conventional means 28, such as threaded fasteners or rivets.

Legs

12 and 14 and arm 20 are similarly pivotably joined by conventional means 30. Each of

arms

20 and 22 is pivotably joined to back frame 26 at 32 and 34 by means which may be the same as used for joining the legs to the arms. Curved

plates

36 and 38 are riveted or otherwise fastened to the lower portion of

legs

12 and 14. The bottom part of

curved plates

36 and 38 is cylindrical, and

tips

40 and 42, made of rubber, plastic or other slide resistant material, are fitted thereon to prevent the chair from sliding. Rod 44 extends horizontally between

legs

16 and 18 to provide lateral support therefor.

Back frame 26 is formed from a continuous piece of U-shaped tubing, and as such it comprises

parallel frame members

46, 48 and cross member 50, Seat frame 24 is constructed in the same manner as back frame 26, and comprises parallel frame members 52, 54 and cross member 56.

Parallel frame members

46 and 52 are pivotably joined at 66 and 68 to triangular plates 58 and 60 spaced on either side of said parallel frame members. Parallel frame members 48 and 54 are pivotably joined to spaced

triangular plates

62 and 64 at and 72 in the same manner as

parallel frame members

46 and 52. The means used to join said parallel frame members to said triangular plates may be rivets, threaded fasteners or other conventional means.

Parallel frame members 52 and 54 are pivotably joined to the inside of

legs

14 and 12, respectively, by means of either threaded fasteners or rivets 74 and 76.

Washers

78 and 80 may "be provided between said legs and said parallel frame members, Rod 82 is parallel to cross members 50 and 56 and extends through and beyond

triangular plates

58 and 62. Said rod 82 is prevented from moving longitudinally in said triangular plates by crimping or other conventional means. As shown in FIGURE 1, when chair 10 is in its open position, rod 82 rests against

legs

16 and 18, and thereby supports the 4 back of seat frame 24 and the bottom of back frame 26.

To form the seat and back of chair 10 flexible spaced slats 84 are provided. Said slats are made of a strong flexible material such as steel tempered to provide a spring-like action. Other strong flexible materials, of course, may be used. Bent tabs 86 depend from both sides of slats 84 and are provided with holes 88 through which fasteners 90 extend, such as rivets 90.

Referring now to FIGURES 2 and 4 where the detailed structure of the connection between slat 84 and parallel frame member 52 is shown, it can be seen that in its unloaded position slat 84 stands away from the frame structure. As shown in FIGURE 4, slat 84 is curved about its longitudinal axis, and makes contact with the top of frame member 52 only at its edges. Bent tab 86 is equidistant from the edges of slat 84 and makes contact with parallel frame member 52 only in the area of hole 88. As shown, hole 88 is larger than the body portion of fastener 90. Thus, tab 86 is loosely held in contact with parallel frame member 52. It should 'be noted that although tab 86 is free to move in the vertical plane, it has no freedom of movement in the horizontal plane.

FIGURE 3 shows the position assumed by slat 84 and tab 86 after a load, represented by the arrow, has been applied to it. The load would in the usual case be the body of a person sitting in chair 10'. The effect of the load is twofold. First, it forces the slat 84 flat and across its width against parallel frame member 52. Second, slat 84 bends around parallel frame member 52 such that it makes contact with it over an arcuate angle of 90 or greater,

From the foregoing, it is apparent that slats 84 give or bend in two right angular directions. This give is exclusive of any small flexure in the parallel frame members. The give simulates the action of fabric under load, and to the person sitting in chair feels as if he is sitting on fabric.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.

I claim:
