SPRING CLIP Filed Dec. 22, 1959 Patented July 1, 1941 SPRING CLIP Harold Greenhill, Chicago, Ill.

Application December 22, 1939, Serial No. 310,501

11 Claims.

The invention relates generally to fastening devices, and more particularly to fastening devices for securing coil springs to one another or to a border wire or the like.

The invention has among its objects the production of a fastening means of the kind described which is simple in construction, efficient, durable, and very inexpensive.

Another object of the invention is the production of a fastening device which may be secured to the spring coils in one operation without the use of tools or the like.

Another object of the invention is the construction of such a device which may be constructed to secure either one or a pair of springs to a border or intermediate wire or bar.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described and more particularly pointed out in the appended claims.

In the drawing wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a top plan view of a portion of a coil spring andborder wire fastened together by a device made in accordance with the present invention;

Fig. 2 is a View of the devicein inverted position; Fig. 3 is an end elevational view of the device;

Fig. 4 is a top plan view similar to. Fig. 1 of thedevice constructed to secure two spring coils to an. intermediate wire or tape;

Fig. 5 is a perspective view similar to Fig. 2, showing the device illustrated in Fig. 4 in an inverted position;

Fig. 6 is a sectional view taken approximately on the line li6 of Fig. 5 with the device in its normal position; and

Fig. 7 is an end elevational view similar to Fig. 3 of the clip in its normal position.

The present invention is intended to be primarily used for fastening spring coils such as those used, for example, in mattresses, box springs, or the like, to connecting border or intermediate elements, the construction shown in Figs. 1 through 3 being intended for use in securing a single spring coil to a border strip or the like, while the construction shown in Figs. 4 through 7 is intended for use in securing a pair of coils together or to an intermediate connecting strip. In both constructions, however, the same principles of the invention are utilized.

Referring to the construction illustrated in Figs. 1 through 3, l represents the upper or end loop of coil spring similar to that used in inner spring mattresses or box springs, which is secured to the fiat wire strip 2 by the fastening member or clip designated generally by the numeral 3. The clip 3 comprises a base member or portion 5 positioned on one side of the strip 2. Extending transversely to the base portion along opposite longitudinal edges thereof are

side portions

5 and 6, respectively, these side portions in the construction shown in the drawings being constructed from the same piece of material forming the base portion 4 by bending such material along substantially parallel lines. The portion 5 is bent inwardly adjacent its free edge to partially overlie the base portion 4 and strip 2, as shown at l, the extreme ends 8 being positioned relatively close to the strip 2, while the. intermediate or central portion 9 is spaced a greater distance therefrom to provide a recess or pocket i i. The other side portion 6 is provided with projections or ears I2 adjacent the ends thereof, as shown particularly in Figs. 2 and 3. The loop I of the spring coil is positioned adjacent the face of the strip 2 opposite the base portion 4 with the portion l of the loop positioned in the pocket H, as shown. The projections or ears H on the side portion 6 engage the loop I of the coil, thereby securely locking the strip 2 and spring to one another.

The clip, spring coil and strip are assembled as follows:

The clip is placed upon the strip as shown in Fig. 3, this being readily accomplished by passing the strip between the side walls 5 and ii of the clip. The portion l of the spring is then positioned adjacent the pocket H in approximately the position shown in dotted lines in Fig. 3, after which the loop is rotated into the position shown in Fig. 3, the loop being spread adjacent the projections 82 by laterally compressing the loop towards the portion 1' thereof as indicated by the arrow, which will thereby allow the loop to clear the projections. Upon expansion of the loop into its normal position, the projections [2 will engage and at least partially overlie the loop, thus locking the same to the clip and the strip. It might be mentioned that while the elements will be securely held in place, if desired, either or both of the

side portions

5 or 6 could be deformed inwardly towards the strip by means of a suitable tool, thereby providing additional securement. However, as previously stated, one of the advantages of the present construction is that such deforming is not required, although if desired, it may be performed. The elements as illustrated will securely fasten and maintain the parts in locked relation.

The construction shown in Figs. 4 through 7 embodies the general construction shown in Figs. 1 through 3, but is provided with additional means for securing the second coil. Referring to Figs. 5, 6, and '7, in the device designated generally by the numeral E3, the base M- corresponds to the base 3 illustrated in Figs. 1 and 3. Similarly, the side member i5 corresponds to the side portion 5, the two side portions !6 to the side portions 6, and projections 22 to the projections l2. The portion I of the spring is engaged with the portion 5, with projections 22 overlying the loop, thereby locking it to the strip in the same manner as the clip 3. The base portion It of the clip i3 is also provided with a pair of additional side members l5 adapted to engage the loop 2! of the second spring coil, while disposed intermediate the two side portions 16 is a side member l6 adapted to engage the loop 2| on the side of the wire forming the same opposite the side members !5'. Both the members I5 and Iii are curved to overlie the loop, and as the member Hi is on the opposite side of the wire from the members E5, the loop member will be securely held in place therebetween. The loop I, clip l3, and the strip 23 are assembled in the same manner as described for the construction shown in Figs. 1 through 3. In connecting the loop 2! with the clip, the portion 2! of the loop is engaged with the intermediate side member Hi, the loop being positioned approximately as shown in dotted lines in Fig. 6. The loop is then compressed on opposite sides of the clip as indicated by the arrows in Fig, 4 until the same will clear the portions l5 when the loop is rotated from the position shown in dotted lines to the actual position shown in Fig. 6. When the loop is released, it will assume the position shown in Fig. 5 and be securely locked to the intermediate wire strip 23.

It will be noted from the above description that I have provided a device for securing single or double spring coils to a border or intermediate wire strip, in which the coil may be readily secured to the strip without use of tools, etc., to deform the device. In the present device, the coils or wire strip may be assembled merely by interlocking them with the clip.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit and scope of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described or uses mentioned.
