BED SPRING Filed April 9, 1956 i .22(27 H4 T27 A United States Patent BED SPRING Louis Elliott Frey, Los Angeles, Calif,

Application April 9,1956, Serial No. 577,047 A6 claims. (c1. s-zas) This invention relates to a bed structure.

At the present time, a bed customarily includes a coil or box spring with a mattress loosely disposed above it. The bed covers, including sheets, blankets, bedspreads, etc., extend across the top of the mattress with their lower ends being tucked between the mattress and spring at the foot of the bed. v

The end portions of these articles of bed covering when tucked between the mattress and spring cause a lumpiness at the foot of the bed which makes it impossible to achieve a neat and tailored appearance.

It is an object of my invention to provide a new and improved bed structure which automatically eliminates any lumpiness or unsightly appearance which results from tucking in the covers in the normal manner. This lumpiness usually occurs particularly at theV corners of the bed where the sides and ends of the bed coverings overlap. This results in several thicknesses of bed coverings, which displace the mattress upwardly from the spring` In essence, my invention contemplates a bed structure having means to receive and accommodate the ends of the bed coverings between the mattress and spring without affecting the positioning of the mattress and without adversely affecting the appearance and comfort of the bed. In the preferred embodiment of my invention, such means comprises forming the portion of the spring adjacent the foot of the bed in such a manner that space is provided to accommodate the ends of the bed coverings without their becoming bunched up and deforming the top surface of the bed. e

It is accordingly an object of my invention to provide a novel bed or spring construction having all of the advantages and benets of the constructionset forth above. It is a further object of my invention to provide such a bed structure which is substantially as economical to manufacture as a conventional bed structure and which is far more satisfactory in performance. n

While my bed structure is capable of universal use,'it is believed to be particularly useful in hotels, where maids are careless in making beds, andin studio couches and sofa beds, which become unsightly and uncomfortable fordaytime use due to the bed covering ends which are disposed between the spring and mattress.

My invention also comprises such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawings a preferred embodiment of my invention, it should be understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawings,

Fig. 1 is a side elevational view of a bed, with the foot portion broken away to show my bed spring construction in use;

Fig. 2 is an enlarged perspective view of one corner of the foot portion of the spring;

Fig. 3 is a top plan view of the foot portion of the Spring;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3, with the bed coverings shown in dotted lines.

A preferred embodiment which has been selected to illustrate my invention comprises a coil spring unit 10 without cover, the major portion of which is constructed in a substantially yconventional manner. The spring 10 is substantially rectangular in shape and includes a plurality of inverted helical coils 11 which extend Vin'rows across the spring 10. The lower ends of the coils 11 are attached to a base which includes a substantially rectan-V gularbase frame 12 and a plurality of transverse sup porting members 13. The upper ends of the coils 11 are attached to each other by aV plurality of diagonally extending coil springs 14 or other equivalent tying members.

The spring 10 is customarily mounted on a bed frame 15 having a roller 16 beneath each corner thereof. A mattress 17 is disposed above the spring 10, Vwith a pillow 18 and a plurality of bed coverings 19 including sheets and blankets disposed above the mattress. A bedspread 20 extends over the bed coverings 19 and pillow 18.

The spring 10 is provided with a conventional substantially rectangular top frame 21 which extends around the edge of the spring. The novel features of this embodiment of my invention lie in the construction of the portion of the spring 10 adjacent the foot of the bed.

Adjacent the foot portion of the spring 10 I provide a sub-frame 22, which is substantially rectangular in shape. The sub-frame 22 comprises a pair of parallel sides 23 and 24, a cross piece 25 and a pair of pivot portions 26. The pivot portions 26 extend parallel'and directly adjacent to the end of the frame 21 which extends along the foot of the bed. A pair of clamps 27 extend around the pivot portions 26 and the eud of the frame 21 to pivotally attach the sub-frame 22 to the frame 21.

The sides 23 and 24 of the sub-frame 22 extend di-` ends of the frame 21 and also extends adjacent and parA allel to the cross piece 25 of the sub-frame 22.

4A plurality of tie cords 28 are attached at their upper ends to the sub-frame 22 and at their lower ends to the base 12 or supporting members 13. The tie cords 28 hold -the ysub-frame 22 in a slightly depressed position against the pressure of the coils 11, so that the cross piece 25 of the sub-frame 22 is normally depressed beneath the cross bar 21d. p

It will be noted that the coils-11 which are enclosed ,I within the sub-frame 22 are attached thereto, while the coils enclosedwithin the remainder of the yframe 21 areA attached toit and'to'the cross bar 21a. In this regard, the rows of coils 11 have been designated alphabetically. It will be noted that one side of row A is attached to the foot portion of the frame 21, while the opposite side of row A is connected to row B. The end 'coils of rows B and C are connected to the sides 23 and 24 of the subframe 22. The other side of the coils of row B is connected to row C, while the opposite side of row C is connected to the cross piece 25 of the sub-frame 22. The coils of row D are connected on one side to the cross piece 21a and on the other side to the coils of row E. The remainder of the coils are attached to the frame 21 and to each other in the conventional manner.

In use, since the cross piece 25 is normally held in a depressed position with respect to the frame 21, a recess Patented May 6, 1958` is provided in the box spring inwardly from the foot thereof, which recess becomes gradually deeper from the foot of the bed toward the cross piece 25. This recess is adapted to receive and accommodate the ends of the bed coverings, including the portions which are tucked in from the tfoot of the bed 'and overlapping portions which are tucked in from both sides of the bed adjacent to the foot. All of these coverings canbe accommodated without causing the foot portion of the mattress 17 to rbe disturbed from its position.

It will be noted that the top line of the spring is unaffected, since the frame 21 is constructed in the same manner as in a `conventional spring. When the bed is viewed from the side, the appearance is thus identical with that of a conventional bed and the recess for receiving the bed coverings is not visible.
