Description

July 26, 1938. J. M. CAUGHEY SPRING CUSHION Filed Oct. 13, 1937 ATTORNEYS.
Patented July 26, 1938 UNITED STATES PATENT OFFICE SPRING CUSHION Application October 13, 1937, Serial No. 168,717
6 Claims.
This invention relates to a spring cushion.
This invention particularly. concerns the securing together of the bottom plate, the unit spring assembly and bottom frame of a spring cushion 5 and relates to a novel clip which not only secures these members together but also serves as a support for the peripheral portions of the bottom plate.
In the drawing:
10 Fig. 1 is a top plan view of a spring cushion with parts broken away to show the various members of the spring cushion assembly.
Fig. 2 is a section along the line 22 of Fig. 1.
Fig. 3 is an enlarged detail vertical section 15 through the bottom frame showing the clip in elevation before the clip has been bent down to secure the bottom frame, bottom plate and unit spring assembly together.
Fig. 4 is an enlarged detail similar to Fig. 3
but showing the clip in final position securing the bottom frame, bottom plate and unit spring assembly together.
Figs. 5 and 6 are vertical sections through the frame showing modified forms of the clip as- 25 sembly.
Referring more particularly to the drawing the spring cushion assembly comprises a bottom frame I defining an opening 2, a bottom closure plate 3 which closes the opening 2, a unit spring 30 assembly generally designated 4, and a cover 5 of trimming fabric, leather, or other suitable material for concealing the spring assembly and frame. The spring assembly 4 is assembled as a unit in the well-known manner before it is mount- 35 ed upon the bottom plate and frame.
The unit spring assembly 4 comprises a plurality of coil springs 6 which have their top convolutions connected together by the usual cross stay wires I. The bottom walls of the springs 4O are connected by the metal strips 8 of channel cross section which are clamped on to the bottom convolutions of the springs. The unit spring assembly 4 is also provided with the usual top frame 9 which is connected to the outside coil 45 springs 6 of the assembly. This unit spring assembly is old and well-known in the art.
The bottom plate 3 is preferably made from fiber board and has a slightly smaller perimeter than the inside perimeter of the frame I so that 50 it can fit within the frame I. The sheet metal frame I preferably is of J cross section. The lower inside edge of the frame I is provided with an inwardly turned lip Ill. The opening defined v by the frame I is bridged by the spaced slats II 55 which are fixed at each end to the frame.
The bottom closure plate 3 rests upon, and is supported by, the spaced slats II. It is proposed to use a plurality of clip members not only for supporting certain portions of the plate 3 but also for securing the plate 3, bottom frame I and 5 unit spring assembly 4 together.
This clip is generally referenced I2 and is shown in section in Fig. 3. The clip I2 is made from an initially flat strip of metal having a lower portion I3 of J section which corresponds 10 in shape and fits within the J frame I and is retained against vertical upward movement by the overhanging lip Ill. The clip I2 has an intermediate return bent portion I4 which serves as a seat upon which the plate 3 rests and is supported. The clips I2 are inserted in the sides I5 of the J frame i between the slats I I and along the ends I6 which run parallel to the outer slats II. It is evident that the portions of the plate 3 along the end I6 of the frame are supported along the edge by the clips I2 and the portions of the plate 3 along the sides I5 and between the slats II are also supported along the edge by clips [2.
Since the J frame I preferably is initially formed with the inwardly turned lip In, to interengage the clip I2 with the frame I, the end I I of the clip I2 is first inserted behind the lip III of the frame I and the clip thereafter tilted or swung into the position shown in Fig. 3 so that it is nested within the J frame I and the interengage ment of the end ll of the clip and the inwardly turned lip ID of the frame prevents the clip I2 from being drawn vertically upwardly of the frame.
After the clips I2 have been inserted in the frame I, the bottom plate 3 is then positioned upon the slats II and the seats I4. The unit spring assembly 4 is next positioned upon the bot tom plate 3 and thereafter the upper end I8 of each clip I2 is turned inwardly of the frame I and downwardly toward the seat I4 which securely clamps the plate 3 and unit spring assembly 4 against the seat I4. Thereafter the cover 5 is applied to the spring cushion assembly and frame I in any well-known manner.
A modified form of the bottom frame is shown in Fig. 5. Here the bottom frame 20 is of J section but the inwardly turned bead I0 is omitted. Therefore in this construction the clip I2 is welded to the frame I as at 2|. Except for these differences the bottom plate 3, unit spring assembly and frame are secured together by the clip I2 in the same fashion as above described.
In Fig. 6 the bottom frame 20 is of J section the same as that shown in Fig. 5. In this form of the invention the clip 22 comprises a strip of metal in the form of an L which is welded to the frame 20 as at 23. The shorter leg 24 of the clip serves as a seat for the bottom plate 3 in a fashion similar to the seat M of the principal form of the invention. The longer leg 25, similarly to the portion l8 of the clip I2, is turned downwardly over the unit spring assembly thus clamping the spring assembly and bottom plate 3 together and between the bent down leg 25 and the seat 24.
