9 Claims.

This invention relates to spring foundations for upholstered furniture. It is particularly directed to an anchor or bracket for connecting an end of a zig-zag spring to the seat frame. This application is a continuation in part of application Serial No. 530,609, filed by applicant April 12, 1944, and now Patent No. 2,439,789, granted April 20, 1948.

An object of this invention is to provide a highly improved anchor attachable to the upper end of a wall of a seat frame and onto which one end of a zg-zag spring may be quickly and easily engaged, and which will prevent the spring from accidentally becoming disengaged.

Another object of this invention is to provide a bracket of the character described which may be made of stamped sheet metal, and which may be attached to a wall of a seat frame by a pair of nails or the like fastening means, and having a hooked portion to engage one legof a bent back end abutment loop of a zig-zag spring, and a portion to engage beneath the other leg of the abutment loop, the construction being such that the abutment loop may be easily engaged with the bracket after the bracket has been attached to the frame, by a hooking action.

Yet another object of this invention is to provide a bracket of the character described having a portion formed with openings to receive fastening means for attaching the bracket to the seat frame, an integral hook portion to engage with one leg of a bent back abutment end loop of a zig-zag spring, and a portion interposed between the other leg of the abutment loop and the top wall of the frame,'whereby to prevent said outer leg from contacting the frame.

Still another object of this invention is to provide a compact and durable spring anchor of the character described which shall be relativel inexpensive to manufacture, easy to attach to a seat frame, and which will firmly and securely anchor one end of a zig-zag spring to a seat frame, and which shall be practical and eificient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention,

Fig. 1 is an elevational view of a spring seat embodying the invention;

Fig. 2 is a partial top plan view thereof;

Fig. 3 is a partial perspective view showing one end of a spring clamp to a seat frame wall by a clamp embodying the invention;

Figs. 4, 5, 6 and '7 are views similar to Fig. 3 and illustrating modified forms of the invention.

Fig. 8 is a side elevational cross sectional view of a spring foundation embodying the invention, and provided with a spring edge construction;

Fig. 9 is a partial, top plan view thereof.

Fig. 10 is a perspective view of a spring employed in the spring edge construction in Figs.

8 and 9. L a I Fig. 11 is for a similar construction of Fig. 9 and illustrating a modified construction.

Referring now in detail to the drawing, Ill des ignates a spring foundation for upholstered- Each loop 20 comprises an end leg 2!, and a next to the end leg 22 connected thereto by a curved or semi-circular portion 23.

The bent back abutment loops ZEI of spring l2 are attached to the front and rear walls It and I1 respectively by the brackets l3, l4. Said brackets may be similar in construction if desired, or the rear bracket may be constructed as shown in my Patent No. 2,257,633, issued September 30, 1941.

Spring I 2'is connected to bracket I 3, in the manner shown in Fig. 3 Front bracket it may be made of stamped sheet metal and comprises a vertical wall 26 contacting the outer surface of frame wall l6. Wall 26 may be formed with a pairof through openings to'receive nails 28 or other fastening means driven into the frame. wall for attaching the clamp to the frame wall. Wall 26 extends to the upper end of the frame wall.

Extending from wall 26 is a horizontal hooked or channelled wall 29 contacting the upper surface of the frame wall [6. The channel wall 29 forms frame Wall Hi. If desired, wall may be curved downwardly and formed at its end with an upwardly curved lip 38a to confine arm 2| of the end loop.

It will be noted that the leg 22 of the abutment loop 28 is engaged within the channel 29a formed by the channel wall 29. Leg 2| of the abutment loop contacts the upper surface of bracket wall or portion 3|). It will be noted that the width of the bracket is less than the width of spring [2 so that the bracket can fit within the abutment loop 20. One end of the spring may be first connected to rear bracket J4. The other end may then be grasped by any suitable tool and hookingly engaged with bracket l3. The

connection of the front end of the spring with bracket I3 is therefore quick and easy. After it is connected it will not accidentally come out of the bracket. When pressure is applied to the spring as by a person sittin on the seat, leg 21 :will be forced downwardly on wall 30 which protects the wood frame wall from the .spring. The hook or channel ,29 firmly engages a'leg 22 of the abutment loop to anchor the spring to the frame.

In Fig. 4 there is shown a bracket illustrating a "modification, embodying the invention for anchoring one end of the spring l2 to a seat frame wall. Bracket 43 may be made of sheet metal and comprises a fiatnarrow wall 4| contactingthe top surface "in. of frame wall-l 6. Said wall 4| is formed adjacent the ends thereof with openings to receive nails or fastening means 42 driven downwardly into the-frame wall. liixtending from wall 4| is a channel wall 43 forming a hook or channel opening outwardly. Bent back from channel wall 43 is a wall inclined rearwardly and downwardly and contacting the top surface lie of frame wall 16. 'Wall '44 is formed with an upwardly curved lip 44a at its end to confine leg 2|. It will be noted that channel wall 43 as well as the part of wall 44 adjacent thereto are formed with notches or cutouts .45 at the opposite ends thereof, whereby said channel wall .and adjacent wall are narrower than wall M or the outer end of wall 44. This construction exposed the-nail holes and permits nails to be driven downwardly through said openings. Spring I2 is engaged with bracket in the same manner as it is engaged with clamp I3. Leg 22 is received within a channel formed by wall 43 and leg 2| contacts the top of wall '44.

In Fig. 5 there is shown a bracket 58 illustrating another form of the invention. Bracket is also made of .sheet metal and comprises a front wall 5| formed with openings for nails 28,- and contacting the front surface of the :frame wall l6. Extending from wall 5| ,is a bent back curved channel wall 52 from which there extends an inwardly and downwardly inclined well 5.3. Bracket 59 is similar to bracket I13 except that wall 153 is formed with a pair of parallel slits 5.5, and the metal between the slits is pressed upwardly to form a than 56. Leg 2| of the abutment loop 20 extends between the strap 56 and wall 53.. .Leg22 of the abutment 100D engages the channel wall or hook 52.

In Fig. 6 there is shown a bracket 60 similar to bracket 50 except that the wall 53 thereof is formed with slits and the metal between said slits is pressed downwardly to form a strap 6|. Leg 2| of the abutment loop then passes beneath wall 53 and between said wall .and the strap 61 as clearly illustrated in the drawing.

In Fig. I? there is shown a bracket 10 for anchoring one end of the spring l2 to a frame wall l6. Bracket 10 comprises a front wall H contacting the outer surface of the frame wall and formed with openings to receive nails or other fastening means 28 for attaching the bracket to the frame wall. Extending from the upper end of wall H and resting on the upper surface of the frame Wall is a horizontal hook or channel wall 12. Extending from the channel wall '12 in an inward and horizontal direction is a wall M. Extending from the rear end of wall 14 is an upwardly inclined wall 15. Wall 14 is formed adjacent each of the side edges thereof with a pair of horizontal slits 16 forming tabs 11 bent downwardly and contacting the upper surface of the frame wall.

It will be noted that the tabs i1 are adjacent the upwardly bent wall 15. Leg 2| of the end abutment loop of the spring l2 contacts the top of wall I4 and abuts against wall l5. Leg 22 of the abutment loop engages within the channel or hook 'l3 formed-by wall or hook'ls as with the other brackets.

Referring now to Figs. 8, 9, and 10, there is shown a spring foundation or spring seat construction 10a, comprising a seat frame I! having sidewalls l5, a front wall [6, and a rear wall I Mounted on front and rear walls are zig-zag springs I2 attached to the frame by means of brackets such as shown in Figs. 3 to 7 of the drawing.

It will be noted that the springs |2, as shown in Fig. 19, are similarin construction, so that the loops pointing in one direction are in alignment, whereas the loops 8| pointing in an opposite direction, are also in alignment.

Mounted on each pair of adjacent springs I2 is acantilever spring .83. Spring 83 comprises a pair of legs 84 and 85, interconnected by an interconnectin portion 86.

Spring .83 is made of a single piece of wire. The leg 84 is shorter than leg 85. At the outer end of leg 84 is an outwardly bent hook 81. At the outer end of leg .85 is an outwardly bent hook 88. The manner of mounting spring 83 on a pair of adjacent springs 12 is illustrated in Figs. 8 and 9 in the drawings.

.As shown in the drawings, leg 84 passes beneath a pair of adjacent runs 89 of one spring 12, and the hook 81 engages a next adjacent loop 8| disposed on the outer side of spring l2. Leg 84 therefore rests on a run 90 of spring |2 adjacent to the runs '89'beneath which said leg passes.

Leg passes beneath a pair of adjacent runs 9| of the next adjacent spring l2 and the hook 88 engages a loop 92 of said spring 12. The leg 85 is longer than leg .84 and hook 88 engages a loop further along the spring than the loop which is engaged by book 81. Leg 85 rests upon run 9310f spring 12 next adjacent to the runs 9!.

Interconnecting portion 36 is located between the springs l2, as shown in Fig.9 of the drawing. The legs 84 and 85 may be normally substantially parallel and opened up when engaged with the springs -|2.

The springs 83 may be interconnected by an edge wire '95 having end legs 96 formed with hooks 9'5. engaging the end springs l2. Edge wire 93 is attached to springs 83 by clips 93a. It will thus be noted that each sprin 33 acts as a cantilever spring and is supported on a pair of adjacent springs i2, thereby providing a highly proficient spring edge construction.

In Fig. 11 there is shown a spring seat construction Nib, likewise comprising a frame I l on which are mounted a plurality of zig-zag springs I2, supported on the ends thereof by brackets such as shown in Figs. 3 to '7 of the drawing.

It will be noted that each pair'of adjacent springs [2 are symmetrically disposed to one another, so that the inwardly extending loops of the adjacent springs are in alignment with each other, and outwardly pointing loops of adjacent springs are likewise in alignment with each other.

Supported on each pair of adjacent springs I2 is a cantilever spring we. Spring I90 comprises a pair of similar symmetrically disposed legs IDI, interconnected at adjacent ends by a portion I02. At the ends of legs lfll are outwardly extending hooks N13.

The legs iii! are of similar length and the hooks its engage aligned outwardly pointing loops of the spring. Each leg IGI likewise passes beneath a pair of adjacent runs I06 of the zigzag springs, and is supported by an adjacent run H37.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustractive and not in a limiting sense.
