BORDER STABILIZERS Filed Aug. 26, 1960 2 Sheets-Sheet 2 r i- INVENTOR.

p MA rm 1 I 5 A TIOPNEY United States Patent Q York Filed Aug. 26, 1960, Ser. No. 52,269 10 Claims. (Cl. 351) This invention relates to border stabilizers for mattresses, upholstered items, and the like, and is related to stabilizers of the class illustrated in United States Letters Patent No. 2,509,831, issued May 30, 1950, and constitutes a continuation-in-part of applications for Patent Serial Nos. 767,655 and 835,263, filed October 16, 1958, and August 21, 1959, both now abandoned.

Among the objects of the present invention it is aimed to provide a stabilizer of the c ass illustrated in United States Letters Patent No. 2,509,831 in which the laterally extending ends are characterized by circular loops forming the supports or abutments for the ends of a heli2al spring to supplement the yieldable resistance to vertical compression by yieldable resistance to longitudinal tension thereby to counteract torsional strains, that is re sistance to torsional strains, and minimize the tendency to bulging.

These and other features, capabilities, and advantages of the present invention will appear from the snbjoined detailed description of specific embodiments thereof illustrated in the accompanying drawings in which:

FIG. 1 is a fragmental perspective of a mattress equipped with the improved stabilizer made according to'the invention discolsed in United States Letters Patent No. 2,509,831.

FIG. 2 is an enlarged side elevation of the stabilizer aiishown in FIG. 1.

FIG. 3 is a section on the line 3-3 of FIG. 2.

FIG. 4 is an enlarged side elevation of a stabilizer made according to a second embodiment of the invention.

FIG. 5 is a plan view of the embodiment shown in FIG. 4.

FIG. 6 is a fragmental enlarged perspective of one end of the stabilizer shown in FIG. 4.

FIG. 7 is a section on the line 77 of FIG. 6.

FIG. 8 is an enlarged fragmental perspective of a third embodiment showing one end of the stabilizer.

FIG. 9 is a section on the line 9-9 of FIG. 8.

FIG. 10 is a side elevation of a stabilizer on a smaller scale than that shown in FIG. 4 of a fourth embodiment of the invention.

In the embodiment illustrated in FIGS. 1, 2 and 3, the stablizer 1 made according to the invention disclosed in United States Letters Patent No. 2,509,831 consists essentially of upper and lower abutments, outwardly extending extensions between said abutments and inwardly extending loops formed in the outer ends of the outwardly extending extensions. More specifically, the stabilizer 1 composed of a yieldable material such as wire or narrow fiat stock is provided with two outwardly extending pairs of

inclined sides

2, 3 and 4, 5, constituting outwardly extending extensions, connected to one another by the

circular loops

6 and 7 respectively constituting inwardly positioned abutmeuts such as the inwardly extending loops formed at the outer ends of said outwardly extending extensions. The lower

inclined sides

3 and 5 are connected by the lower horizontally extending side 8 constituting the lower abutment which is connected by the helical connecting spring 9 to the lower border wire 10 and the upper inclined sides 2 and 4 terminate in the upper sides 11 and 12, constituting an upper abutment, which overlap and are connected to one 3,022,521 Patented Feb. 27, 1962 another by any suitable means such as the twists 13 and 14 and then connected by the helical connecting wire 15 to the upper border wire 16 of the mattress frame.

The

sides

11, 2, 3, 8, 5, 4 and 12, constituting'an endless unit, and

loops

6 and 7 are part of a single resilient wire. A transverse bracing extension such as the second helical spring 17 is provided with

hook formations

18 and 19 at its ends which engage the

loops

6 and 7 respectively and maintain the

loops

6 and 7 at a predetermined tension relative to one another determined by the cooperation of the elasticity in the spring wire of the unit 1 and the elasticity in the helical spring 17. The spring 17 therebyin turn facilitates adjusting the tension in the stabilizer either by eliminating the helical spring 17 and relying only on the rhomboid construction 1 or twisting the helix of the spring 17 more or less according to the tension required.

Excellent results have been achieved when the wire constituting the unit 1 illustrated in FIGS. 1, 2 and 3, is No. 13 gauge, of about 0.0915" in diameter and when the wire of the helical spring 17 is composed of wire No. 17 gauge of about .052" in diameter and the wire constituting the unit 1 is elliptical in shape having either a major axis of 0.120" and a minor axis of 0.080" or a major axis of 0.146" and a minor axis of 0.073", as disclosed in copending application for Patent Serial No.

766,598 filed on October 10, 1958, and executed on or about October 9, 1959, by Gustav Drews, now abandoned.

With regard to adjustment by means of the helical spring 17, attention is called to'the fact that when the wire of the unit 1 is composed of high carbon steel wire No. 13 gauge of about 0.0915 in diameter and in size approximates 8" from the inner periphery of loop 6 to the inner periphery of the loop 7 of about 10%" from the outer periphery of the loop 6 to the outer periphery of the loop 7 and about 5 /2" from the outer periphery of the sides 11 and 12 to the outer periphery of the side 8, and the helical spring 17 in its free unstretched extent is about 8" in length, the diameter of the helix about /2" and the Wire is composed of high carbon steel of about No. 17 gauge of about 0.052" in diameter, that then the load will be increased from two pounds to two and three-quarter pounds when the helix of the wire 17 is given two turns as contrasted to its free unstretched condition.

The embodiment shown in FIGS. 4, 5, 6 and 7 differs in part from the embodiment shown in FIGS. 1, 2 and 3 in that the ends of the outer wire 20 are not positioned adjacent to one of the border wires such as the

border wires

10 and 16 but are formed into

circular loops

21 and 22 which are disposed adjacent to one another clear of, and intermediate, the

border wires

23 and 24 where they are connected to one another by any suitable means such as the rivet 25 of this embodiment or the clip 26 of the embodiment shown in FIGS. 8 and 9.

Furthermore, the stabilizer 27 of the embodiments of FIGS. 4 to 7 inclusive instead of being six-sided is substantially oval or elliptical with the intermediate substan tially

straight areas

28 and 29 of the wire 20 presenting a single wire for connection to the

border wires

23 and 24 respectively by the

helical wires

30 and 31 respectively. With this construction the diameter of the helices of the

wires

30 and 31 may be reduced materially, snugly to connect the

portions

28 and 29 of the wire 20 to the

border wires

23 and 24 and thus prevent any unnecessary movement and consequent rattling between the wire 20 and the

border wires

23 and 24 when the mattress is compressed during use.

In the embodiment shown in FIG. 10, the wire 32 is bent to form a six-sided unit such as disclosed in FIGS. 1, 2 and 3 but retaining the advantage of presenting a 3 single wire area to the

border wires

33 and 34 and also the further advantage that the crimping of the ends of the wire 32 is obviated, the rivet 25 of FIG. 6 or the clip 26 of FIG. 8 taking the place of the crimping thereby materially reducing the cost of manufacture without 1mpairing the efiiciency of the unit.

The

loops

21 and 22 of the embodiment illustrated in FIGS. 5 and 6 are disposed at one end of the elliptical stabilizer 27 with the wire 20 formed into a loop 35 at the other end of the stabilizer to enable the helical intermediate spring 36 to be connected at one end to the rivet 25 connecting the two

loops

21 and 22 to one another, and at its other end to the loop 35 both within the elliptical conformation of the wire 20.

In the embodiment shown in FIG. 10, the rivet 37 18 shown as connecting together the small loops at the left end of the unit 32 to one another, such as the

small loops

21 and 22 of the embodiment shown in FIG. 5 and the loop 38 shown at the other end of the unit 32 to enable the helical tension spring 39 to be connected at one end to the rivet 37 and at the other end to the loop 38.

With the embodiment illustrated in FIGS. 4 to 7 inclusive the rivet 25 and loop 35 of course present the advantage of enabling the ends of the helical spring 36 to be connected inside of the elliptical formation of the wire 20. The clips 26 of the embodiment illustrated in FIGS. 8 and 9 present the added advantage that one end of the helical spring 40 may be connected directly to the

loops

21 and 22 of the wire 20 and thereby not encircle an additional thickness such as the rivet 25 of the embodiment illustrated in FIGS. 4 to 7 inclusive thereby reducing the width of the unit at this point to a minimum.

The elliptical formation of the wire 20 in the embodiment illustrated in FIGS. 4 to 7 inclusive thus has two outwardly protruding extensions intermediate the

border wires

23 and 24 in which extensions are formed the inwardly

protruding loops

21, 22 and 35 and the six-sided unit 1 illustrated in FIGS. 1 to 3 inclusive consists of two outwardly protruding extensions between the border wires 16 and having inwardly protruding

loops

6 and 7 extending from the middle of each extension.

It is obvious that various changes and modifications. may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
