Application April 25, 1938, SerialNo. 204,018 r 4. Claims. (o 5.252)
The present invention relates to an improved spring construction particularly designed to be utilized in beds.
It is among the objects of the present invention to provide an inexpensive bedspring construction which will be durable, comfortable and will be balanced against distortion in any direction, even though the spring be unevenly loaded at different parts thereof.
Another object is to provide a bedspring with an improved stabilized construction which will eliminate lateral displacement of the upper portion of the spring without causing undue stress upon the lower spring structure and without twisting or disarrangement tending to break or rupture or cause damage to the spring construction as a whole, even though the spring be substantially unbalanced in'its loading.
Other objects will be obvious or'will appear during the course of the following specification. In accomplishing the above objects it has been found most satisfactory to provide a relatively rigid. lower frame of subs'tantialj'strength with 0 cross braces to support the bottom of the main vertical coil springs. The centrally positioned main coil springs are preferably provided with a lattice-like platform or frame whichis clamped between the closed coils thereof. This plat-- form is preferably connected by elongated small diameter coil springs to the bottoms or lower portions of the peripheral main vertical coil springs. The upper frame is more rigid than the center intermediate frame, but less rigid than the bottom frame.
To the upper frame are conn cted the outside edges of the top coils or rungs of the main coil springs, the top rungs preferably beingv in the plane of the upper frame. v
The top or upper frame is preferablystabilized against the lateral displacement by aplurality of downwardly and inwardly inclined stabilizer bar elements which have a four-point diagonal resilient suspension substantially in the plane of the lowermost frame.
In the preferred construction, the lowermost end of the inclined stabilizer is bent into a horizontal plane and is positioned in the plane of the lowermost frame. This bent end is con- 5 nected by four diagonally extending coil springs to the lower rung or coil of the intermediate main coil springs. I
In the drawings which illustrate one of the various possible embodiments according to the 55 present invention, but. to which the. present invention is by no means restricted, since many variations, alterations/and modifications might all be made within the spirit and scope thereof:
' Fig. 1 is a top plan view of the spring construction with the spring being considerably *5- shortened longitudinally and laterally to enable a more compact showing,
Fig. 2 is: a side sectional View upon the line 2-2 of Fig. 1, Fig.3 is a fragmentary bottom view upon 10 the line 3-3 of Fig. 2, Fig. 4 is a transverse sectional view upon the line 4-4 of Fig. 1 taken through the longitudinal axis of the spring.
Referringto the drawings, the spring consists 15 of a lower or bottom rigid frame A, a less rigid upper or top frame B and an intermediate strip metal lattice frame or platform C. The main large'diameter vertical coil springs D connect these frames and. support the upper frame B and the intermediate frame C from the lower frame A.
The stabilizers E are connected between the upper frame B and the lower frame A. The stabilizers E are resiliently attached to the bottoms of the main coil springs D and they preventlateral displacement of the upper frame B.
' The lower frame A consists of a rectangular bar element H] of angular cross section, as best shown in Figs. 2 and 4. The bar [0 is riveted so 7 at B by the vertical flanges II to the upturned ends l5 of the cross members 12. The cross members I2 are bent horizontally at l4 adjacent the frame l0. v The intermediate portions "5 of the cross members l2 are twisted at l'l into a vertical plane, and these vertical portions 16 at l8 receive and are connected to the lowermost rungs or coils IQ of the intermediate coil springs D. The lower rungs 20 of the peripheral coil springs F restupon the horizontal portions !4 of said cross memberslZ.
The upper portions of the vertical cross member I6 are also recessed at 2| (see' Fig. 4) to receive the upturned portions 22 of the crossing wires 23. These wires 23 are substantially in the plane of the lower frame A and they are attached at their looped end portions 24 to the vertical flange ll of the rectangular element Ill.
The wires 23 support the peripheral coil springs F, along the end by the upturned portions 25 projecting inside of the lowermost coils 26, as shownin Fig. 4'. Between the lowermost coil 26 and the upturned 10 1125 along theshort sides of the frame A extend the transverse wires 21 to form a permanent connection. The transverse wires 21 are connected at the ends of the structure A to the vertical flanges l l by loops (not shown) which are similar to those indicated at 24 in Fig. 4.
The longitudinal wires 28 along the long sides of the frames A, as best shown in Figs..2 and 3, have down-turned loops 29, which extend below the horizontal portions [4 of the cross members l2 and engage the edges thereof. The wires 28 on each side of the loops 29 extend over the lower rungs 20 of the peripheral main springs F and lock them in position upon said cross members I 2.
The middle coils 30 of the main coil springs D are brought closer together so as to clamp the intermediate lattice frame C in position. The lattice frame is formed of the crossing strips 3| and 32, the strips 3| having elevated portions 33 to receive the longitudinal elements 3| inside of the closed coils 30 of the intermediate springs D.
The ends of the strips 3| and 32 are respectively connected by means of the downwardly extending elongated small diameter coil springs 34 and 35 to the lower rungs or coils 36 and 31 adjacent to, but removed from, the lowermost rungs of the peripheral springs F.
By including the springs 34 and 35 extending downwardly from the intermediate lattice platform C, it has been found that the lower por tion of the bedspring is stabilized and will most readily resist the downwardly applied deforming stresses without loss of comfort, with the upper portion of the bedspring above the lattice C being under relatively less tension than the lower portion below the lattice 0. Moreover the load upon the stabilizers E is considerably lessened.
The upper frame B consists of a rectangular ring 38 less rigid than the bottom frame B. The rectangular ring 38 is tied at 39 to the sides or edges of the uppermost coils 40 of the peripheral coil springs F, preferably at points at least 90 away from. the points 4| where the springs F are tied together at their uppermost rungs or coils. The top coils 40 of said coil springs B are connected to the intermediate springs D by the crossing diagonal springs 42, which are connected or interlaced together at 43. It will be noted that the peripheral coil springs F are devoid of direct connection to each other, while the various intermediate springs D are not only connected to each other bythe crossing diagonals 42, but are also connected to the peripheral springs F.
It will be noted by referring to Fig. 1 that the bottom frame by reason of the cross beams l2 and the cross wires 21 and 28 will form a series of squares, which coincide with the squares formed by the intermediate lattice C.
It has been found that to obtain maximum stabilization, the lower horizontally-bent ends 44 of the stabilizers E should be centrally located in said squares 45 removed from the frame A by the distance of about one or two squares 45. The lower flattened ends 44 are preferably provided with the holes 46 which receive the inner ends of the coil springs 41, which at their exterior ends are connected to the lowermost rungs l8 of the intermediate coil springs D.
The stabilizers E as shown have vertically extending portions 48, diagonal extending portions 49 and they terminate in a loop 50 which may be rigidly or pivotally connected to the frame B.
Many other changes could be effected in the particular features of bedspring construction designed, and in methods of operation set forth, and in specific details thereof, without substantially departing from the invention intended to be defined in the claims, the specific description here-in merely serving to illustrate certain elements by which, in one embodiment, the spirit of the invention may be eifectuated.
