4 Claims.
This invention relates to a bed spring of an improved construction.
An object of this invention is to produce a more comfortable and luxurious bottom for mattresses and the like.
A further object is to attain ease of manufacture and assembly of the various elements of the construction. l
A further object is to construct a spring in which a minimum of material may be used.
Other objects of my present invention will be apparent to those skilled in the art from the following description and appended claims.
In the drawings accompanying the description,
Fig. 1 is a top view of a portion of my novel spring mattress. Since both ends and both sides of the spring are identical only a portion of the entire mattress is shown,
Fig. 2 is a side view of the structure as viewed from the bottom of Fig. 1,
Fig. 3 is an end view of the mattress as viewed from the right of Fig. l,
Fig. 4 is a horizontal section taken immediately above the lower set of springs as indicated by the line 4*-4 of Fig. 2,
Fig. 5 is an enlarged vertical section taken on line 4 4 of Fig. 2, n
Fig. 6 is an enlarged vertical section taken on line 6-6 of Fig. 4,
Fig. 'l is a sectional View on of the specic means of attaching the cross connecting springs to the springs in the top deck of the structure.
The preferred embodiment of my invention is illustrated in the drawings. A rectangular frame is provided consisting of side bars 1 formed preferably of angle iron and a plurality of cross bars 2 each cross bar being formed of a flat metal strip fastened at its ends 3 to the side bars 1 by a rivet 4. The cross bars 2 are equally spaced and serve to support the spring structure.
The spring structure consists primarily of a lower deck of spiral springs 5 of the well known singlecone shape, relatively few in number and van upper deck of spiral springs 6 of the same shape and relatively large in number. The springs 5 are made of fairly heavy wire, while the springs 6 are made of thinner wire.
The springs 5 in the lower deck are equally spaced and arranged in longitudinal and transverse rows, each transverse row being mounted on one of the cross bars 2. Each spring 5 of one of the longitudinal rows is fastened to a cross bar 2 by a wire 'l being looped about the an enlarged scaleV lower coil of each spring 5 and around its associ-` ated bar 2 in the manner as shown in Fig. 2. The wire 7 extends the length of the frame and secures each spring 5 of that particular longitudinal row to its respective cross bar 2 in the manner illustrated. Each longitudinal row of springs 5 is likewise secured to the cross bars 2 by a wire 7.
The top coils of the springs 5 in the lower deck are joined by the connecting elements 8 aligned at approximately 45 degrees from the major axis of the construction. These connecting elements 8 do not cross the tops of the springs 5 but simply extend across the space between these springs and are attached to the springs 5 as will be described below. The elements 8 may be made either of flat or round wire. 1t will be seen that Vthe elements V8 occur in pairs which cross each other at their mid points. These elements may be joined at these points 8 by some suitable fastening means.
VA border frame 9 is provided for the lower deck of springs and is attached to the top coils of the springs 5 on the outside of the structure by wires 10 which are looped around the border frame 9 and the top coil oi each spring 5 on the outside of the lower deck. Usually one wire 10 is provided for each side of the construction.
Each spring 5 supports four smaller springs 6. Each one of these springs 6 is attached to a spring 5 at equally spaced points around the top coil thereof. The point of attachment in each case is at the point where one of the connecting elements 8 is attached to the spring 5 and for theoutside row of springs 6 at points diametrically opposed to where said elements 8 are attached except for the springs adjacent each corner spring. These spring-s are attachedat points degrees removed from the points named. This particular rela# tionship` may be more Aclearly understood from the showing in Fig. 4 of the drawings.
The lower coil of each spring 6 on the inside of the structure is attached to the upper coil of each spring 5 by the connecting elements 8 being looped through the lower coil of the spring 6 and around the wire of the top coil of spring 5 as shown in Fig. 5.
The lower coil of each spring 6 on the outer edge of the structure except that of the corner spring is attached to its respective spring 5 by wires 1l each wire 11 being used to fasten two adjacent springs 5 to their respective springs 5. Each end of the wire ll is looped around the lower coil of spring 6 and the wire of the top coil of spring 5 as indicated in Fig. 5. The mid portion 0f each wire l1 lies parallel to the sides of the border' frame 9 and is kept in position by the wire passing above and below said wire 11 as indicated in Fig. 4. Each corner spring 6 is attached to its spring 5 by a single wire 13 which may be of flat or round wire, this wire being looped around the lower coil of spring 6 and the wire of the top coil of spring 5.
It is contemplated that for the fastening means referred to viz members '7, 8, 11 and 13 either flat or round wires may be used. Thus it will be noted that the bottom coil of each spring 5 and 6 in theV entire spring construction is fastened to its support in exactly the same manner. This lgreatly simplilies the assembly of the structure.
The arrangement shown affords a particularly simple means or attaching both the connecting elements 8 and the springs 6 to the top coils of springs 5. Thus, each support foreach coil 6 is formed of but two parts viz a wire of the top coil of spring 5 and the wire or connecting element 8. Since these elements 8 are not a-continuous strip across the entire structure but are discontinuous, extending merely across the space between the springs 5, the top coils of springs 5 are permitted to flex freely in any direction from their normal plane.
The upper border frame 12 is provided for the upper deck of springs 6. This border frame is attached to the top Vcoils of the springs 6 on the outside of the structure by a wire 14 being looped around the frame 9 and the top coil of each spring 6 as indicated in Fig. 1. Usually one wire la is rovided for each side of the spring construction.
It will be noted that the arrangement of the springs in both the lower and upper decks is such as to present points of attachment for the border frames at the corners of the construction as well as at the sides and ends.
The top coils of the springs 6 are joined by helical springs 15. Springs 15 are merely illustrated schematically in Fig. 1. In detail, they consist of the structure illustrated in Fig. 7. These springs 15 are likewise aligned at 45 degrees to the major axis of the construction. They are attached to the top coil of each spring 6 and extend across the space between these coils. These springs 15 likewise occur in pairs which cross each other at these mid points.
The springs 15 are attached to the springs 6 in the manner illustrated in Fig. 7. A clip 16 is provided for each spring 15 on the respective springs 6. This clip is made of spring material and is provided with ratchet-shaped shoulders'l?. These shoulders 17 are spaced so as to conform Y.lith the pitch of the coils of the helical spring 15. The extension 18 of the clip 16 embraces the wire of the top coil of spring A6 and is retained on spring 6 in this manner. To attach the springs 15 they are simply pushed into place. The two sides of the clip 16 yield suihciently to allow the successive coils of the spring 1'5 to pass over the shoulders 17. The top coil of spring 6 acts as a stop for the coil 15. The coils of the spring 15 engage behind the shoulders 17 making it necessary to rotate the spring 15 in the proper direction in order to remove it from the clip 16. Thus the springs 15 are easily andsecurely attached to the springs 6.
1t will be noted that in the arrangement shown the top coils of springs 6 overlap the borders of the top coils ci the lower springs 5 so as 'to close up the surface of the spring work very completely. This results in a very comfortable and desirable construction.
Various changes may be made in this embodiment o my invention as will be apparent to those skilled in the art within the scope of the appended claims.
What I claim is:l
1. A spring construction including a lower deck of spiral springs, said springs being arranged in spaced longitudinal and transverse rows, connecting elements connecting the top coil of each spring with the top coil of each adjacent spring aligned at substantially 45 degrees to said longitudinal and transverse rows, said connecting elements extending only across the space between said springs, an upper deck of spiral springs, one of the springs of said upperfdeck being supported on each top coil of the springs in said lower deck at each point where said connecting elements are attached to said top coils and connecting members between the top coils of said upper deck of spiral springs.
