Description

K. K. CUNDlFF TAPE-TYPE BED SPRINGS Filed May 23, 1966 Kw 0d TD m u C K 1 m M Y 7 B 3 M ps0)? RNEYS United States Patent 3,346,891 TAPE-TYPE BED SPRINGS Kenneth K. Cundilf, 3545 E. 21st Place, Tulsa, Okla. 74114 Filed May 23, 1966, Ser. No. 551,993 3 Claims. (Cl. -220) ABSTRACT 0F THE DISCLOSURE Tape-type bed springs comprise a sheet metal frame having a downwardly concave inwardly extending upper flange in which a plurality of slots are formed by tongues of the sheet metal, the tongues extending downwardly outwardly and being downwardly concave. The frame has an inwardly extending lower horizontal flange to which the ends of the tapes are secured, the tapes passing through the slots and encountering no sharp edges because of the rounded tongues and flanges.
The present invention relates to tape-type bed springs, that is, to bed springs in which a plurality of tapes are stretched between opposite sides of a bed frame so as to provide yieldable support for the body of the user.
It is an object of the present invention to provide tapetype bed springs which will impose desirably little wear on the tapes.
Another object of the present invention is the provision of tape-type bed springs in which the frame has great rigidity.
Still another object of the present invention is the provision of tape-type bed springs in which the tension of the tapes can be readily adjusted.
The invention also contemplates the provision of tapetype bed springs in which individual tapes can be quickly and easily removed and replaced when they become worn.
Finally, it is an object of the present invention to provide tape-type bed springs which will be relatively simple and inexpensive to manufacture, light in weight, easy to assemble and adjust, and rugged and durable in use.
Other objects and advantages of the present invention will become apparent from a consideration of the following description, taken in connection with the accompanying drawing, in which:
FIGURE 1 is a perspective view of bed springs according to the present invention;
FIGURE 2 is a side cross-sectional view of the springs of FIG. 1;
FIGURE 3 is an enlarged fragmentary view of a portion of FIG. 2; and
FIGURE 4 is a fragmentary perspective view of a tapeaccommodating portion of the frame.
Referring now to the drawing in greater detail, there are shown bed springs according to the present invention, comprising a rectangular sheet metal frame 1 supported on legs 3. Frame 1 is characterized by relatively long sides 5 and relatively short ends 7; although it will be understood that of course the sides and ends can all be of the same length.
The sides and ends are characterized by upright webs 9 which terminate downwardly in horizontally inwardly extending lower portions 11, which in turn terminate inwardly in upright flanges 13. Upper portions 15 are spaced above lower portions 11, and are integral with the upper portion of upright web 9, and are arcuate and downwardly concave. Each upper portion 15 terminates inwardly in an edge portion 17 that is downwardly inclined and in fact is downwardly concave. Web 9 and lower portion 11 and flange 13 and upper portion 15 and edge portion 17 are all integral and of sheet metal.
Struck or otherwise partially severed from the sheet metal of upper portion 15 is a downwardly inclined tongue 19 which is also downwardly concave. The formation of tongue 19 leaves an opening 21. The upper sur- 5 face of tongue 19 is accordingly convex and smoothly rounded, as is also the upper surface of edge portion 15. The tongues 19 on opposite sides of the frame extend away from each other.
Frame 1 is crisscrossed by a plurality of flat tapes 23 of woven textile material or other flexible but relatively inextensible material. Tapes 23 are horizontal and extend between opposite sides of the frame. Those extending between the ends of the frame are of course perpendicular to those extending between the sides of the frame.
Tapes 23 are disposed generally at the top of the frame and provide a supportive upper surface to the frame for the purpose of supporting the body of the user.
Each tape 23 has rings 25 secured to opposite ends thereof, as best seen in FIGS. 3 and 4. A tension spring 27 is hooked through each ring at its upper end and at its lower end through the eye of a bolt 29. Each bolt 29 extends vertically through lower portion 11 of frame 1 and is screw threaded adjacent its lower end for the reception of a knurled adjusting nut 31 which is disposed 25 on and acts against the underside of lower portion 11 of frame 1.
Braces 33 in the form of upright webs extend between and are secured to opposite sides of frame 1 for the purpose of rigidifying the frame and to resist the forces imposed on the frame by tapes 23. Braces 33 are positioned on the upper edges of flanges 13.
In use, the tapes are threaded through openings 21 and assembled and tensioned by means of springs 27 and bolts 29 and nuts 31. The tension on the tapes is individually adjustable by manipulation of nut 31, so that tapes that support the heavier portions of the body can be drawn tighter and those that support the lighter portions of the body can remain looser, thereby to improve the posture of the person using the bed springs. Alternatively, all the tapes can be drawn quite tight, so as to provide maximum support.
It will also be observed that replacement of an individual tape when it becomes worn is quite easy, as it is necessary only to release the associated bolt by unscrewing its nut 31, after which the ring 25 can be unhooked from spring 27 and the tape unthreaded from its position and replaced with a new tape.
It is quite important to note also that the configuration of tongue 19 and edge portion 17 minimizes wear on the tapes at the same time that it provides a very simple and easily manufactured construction. The edge portion 17 and tongue 19 are both downwardly concave, so that as the tape changes direction about tongue 19, there is a minimum of stress concentration and hence a minimum of wear on the tape.
In view of the foregoing disclosure, therefore, it will be evident that all of the initially recited objects of the present invention have been achieved.
Although the present invention has been described and illustrated in connection with a preferred embodiment, it is to be understood that modifications and variations may be resorted to without departing from the spirit of the invention, as those skilled in this art will readily understand. Such modifications and variations are considered to be within the purview and scope of the present invention as defined by the appended claims.
Having described my invention, I claim:
1. Tape-type bed springs comprising a sheet metal frame having upright sheet metal sides that terminate upwardly in sheet metal upper portions that extend inwardly and then downwardly, and a plurality of flexible tapes extending between and secured to opposite sides 3 of the frame, said upper portions of the frame having openings therethrough for the reception of end portions of the tapes, each opening being provided by tongues of the sheet metal of the frame partially severed from the frame and bent to provide convexly curved surfaces about which the tapes change direction, the tongues on one side of the frame extending away from the tongues on the other side of the frame, the tongues being bent downwardly from their unsevered position so that they extend below the contour of the said upper portions of the sheet metal frame.
2. Bed springs as claimed in claim 1, said downwardly extending portions of said upper portions of the sheet metal frame being downwardly concave.
3. Bed springs as claimed in claim 1, said upright sides of said sheet metal frame terminating downwardly in inwardly extending flanges, and means securing the end portions of the tapes to said inwardly extending flanges.
