Application October 14, 1947, Serial No. 779,698

1 Claim.

This invention relates to a chair bottom retainer that is especially designed to be used with chair bottoms that are constructed by weaving strips of suitable material or a single piece of material.

At the present time, chair bottoms that are woven from strips of material are woven so that there is an upper and a lower layer of the material. This requires more material than is usually required to provide the sealing surface and, therefore, provides a more expensive chair bottom.

An object of the invention, therefore, is to provide a bottom retainer that will securely retain a chair bottom on the chair and wherein the bottom is only made of one layer of woven material or a single layer of material.

The device thus produces a chair that is less expensive to manufacture, will save time and material in the manufacture thereof, and once completed, will provide a bottom that is substantially stronger than the bottoms that are constructed or woven at the present time.

With the above and other objects and advantages in View, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which:

Figure 1 is a bottom plan view of an embodiment of the invention in place to retain a chair bottom, the legs of the chair being shown in section on the line II of Figure 2;

Figure 2 is a sectional view on the line 2--2 of Figure 1;

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

Figure 4 is a detailed sectional perspective view of a corner of the bottom retaining means;

Figure 5 is a detailed sectional perspective view of a modified bottom retaining means.

Referring more in detail to the drawing, the reference numeral I is used to designate a chair comprising four legs which, being of similar design, will be designated by the numeral l I. In the usual construction of chairs of this nature,

the legs are formed by cross rods or rungs, and I these rungs are grouped in pairs in the same horizontal plane through two sides with one group lying in aplane lower than the other group. In the drawing, the group lying in the upper horizontal' plane will be designated by the numerals I2 and, I2; while the group lying in the lower horizontal plane will be designated by the numerals I 3 and I3 respectively.

This construction is conventional, but must be fully explained to show the conformation of the device embodying the invention to these groups lying in their respective planes.

The chair bottom I4 is applied to the cross rods or rungs by turning the ends of the chair back upon themselves over the cross rods and rungs.

The bottom will, of necessity, have to have the cutouts I in the four corners thereof, pass over the tops of the legs I I.

The bottom retaining means embodying the invention comprises a metal frame I6 having an inwardly inclined marginal edge depending flange H which, engaged by screws I 8 that enter the legs I I, retain the frame in bottom retaining position, as shown in Figure 1. Since the cross rods or rungs lie in different horizontal planes, the sides of the frame must be positioned in different planes to retain the bottom in position. To provide this structure, the sides I9 of the frame l6 are curved upwardly at their ends at 2|] to place the sides 2| of the frame I6 in a higher horizontal plane than the plane in which lie the sides I9. Thus when the frame is positioned as in Figure 1, the different planes of the sides of the frame will cause the sides to bind the bottom I4 on the cross rods or rungs, and firmly retain the bottom in place.

In Figure 5, there is shown a modified form of the invention, which comprises a wooden frame 22 of substantially the same overall size as the frame It, but, constructed of strips of wood. The frame 22 will have

sides

23 and 24 respectively, which are mortised at their ends as at 25 to place the sides 24 in a lower horizontal plane than'are the sides 23. The edges of the sides are inwardly bevelled as at 26 to conform to the cover as do the inwardly inclined flanges of the frame I6. The mortise 25 provides the means for positioning the sides in different planes, as does the curve 29 of the frame I6.

It is believed that the manner in which the frames are used and their construction will be apparent to those skilled in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination of partsmay be resorted to, provided they fall within thespirit of the invention and the scope of the appended claim.

Having, thus described the invention, what is as new and desired to be secured by ltette Patent is: A c lr bottom retaining means ofthe c acter;.-'d escribed, comprising a frame havin .two sides thereof lying in a different horizontafplane 3 from the opposite sides thereof, means at the ends of the sides for placing the sides in the dilferent planes, and said frame is made of a single piece of strip metal, the sides having inwardly inclined marginal edges and the means for placing the sides in different planes, comprising an upwardly inclined curve formed at the ends of the sides lying in the lower plane.
