4 Claims. (Cl. -351) The present invention relates to a novel spring assembly, and more particularly to a novel mattress structure or the like.

Heretofore a conventional procedure of making mattresses or the like has included the steps of placing a sisal padding over a spring unit, then placing a cotton felt pad over the sisal and enveloping the assembled parts with ticking which includes top and bottom panels and a border strip. In order to provide increased stiffness or support at the corners of the mattress, it has been the practice for a workman to grasp a wad or handful of cotton felt and push it into a corner of the mattress and into engagement with the side of a corner spring prior to the assembly of the border strip of the ticking. The results obtained have not always been satisfactory since the workman frequently is not careful to obtain a correct and uniform amount of cotton for each wad. Furthermore, the cotton wad may not be properly placed in the first instance, and after the mattress has been in use, the cotton wad may become dislodged and displaced even if it was originally properly located by the workmen.

As will be understood, it is the conventional practice to preassemble handle members to the ticking border strip. Thus, unless the workman is careful to position initially the border strip in a proper mmner when sewing the strip to the top and bottom ticking panels, the handles at one side of the mattress will not be properly aligned with the handles at the opposite side of the mattress.

An important object of the present invention is 'to provide a novel mattress structure wherein all of the corners may be more uniformly and quickly formed in a manner which improves the support and appearance of the corner portions of the mattress and enables the mattress to be more economically produced.

A more specific object of the present invention is to provide a novel mattress structure wherein corner pads or blocks of resilient material may be precut or uniformly shaped and may be preassembled with the border strip of ticking material so that when the border strip is applied to the mattress structure, the blocks or pads will be properly positioned at the corners and permanently retained at the corners, which arrangement also facilitates proper lo cation of the handles carried by the border strip.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:

Fig. 1 is a fragmentary perspective view of a mattress structure incorporating the features of the present invention;

Fig. 2 is an enlarged fragmentary sectional view taken along line 22 in Fig. 1;

Fig. 3 is an enlarged fragmentary sectional view taken along line 3-3 in Fig. 1;

Fig. 4 is a fragmentary perspective view showing a portion of the border strip having a corner block or pad preassembled therewith in accordance with the present invention;

Fig. 5 is a fragmentary perspective view similar to Fig. 4 but showing a modified form of the present invention;

Fig. 6 is a fragmentary sectional view similar to Fig, 3 but showing a structure utilizing the embodiment of Fig.- 5; and

Fig. 7 is an enlarged fragmentary sectional view taken along line 77 in Fig. 4.

Referring now more specifically to the drawings wherein like parts are designated by the same numerals through out the various figures, a mattress structure 10 incorporating the features of the present invention is shown in Figs. 1 through 4. The mattress structure comprises a spring unit 12 made up from a plurality of coiled wire springs 14 arranged and retained in predetermined relationship in any known manner. Sisal pads 16 or other suitable insulator means cover opposite sides of the spring unit, and cotton felt pads 18 or the like cover the sisal pads. Top and bottom sheets of covering materials or ticking panels 29 and 22 are positioned over the felt pads 18, and a preassembled border strip assembly 24 described more in detail below has its upper and lower margins sewn or otherwise connected to the margins of the top and

bottom panels

20 and 22 as indicated at 26 and 28.

The border strip assembly 24 includes an elongated'strip 30 of ticking material or the like which is precut and sewn to provide it with the proper width and a predet'ei mined length which is suflicient to enable the strip to extend completely around the rectangular mattress structure only part of which is shown. A relatively'light strip 32 of padding material which is substantially coextensive with the strip 30 is sewn or otherwise secured to the strip I 30 so as to provide the fabric strip 30 with sufficient body to enhance the appearance of the finished mattress structure. In the embodiment of Figs. 1 through 4, four blocks 34 of resilient material, preferably foam rubber-like material, are secured to the strip 30 at predetermined intervals. While only one of the blocks 34 is shown, it will be understood that these blocks are spaced in accordance with the predetermined width and predetermined length of the spring unit 12 so that when the border strip'assembly is applied to the mattress structure, each of the blocks 34 will be located at a cornerof the mattress.

structure as shown in Figs. 1 and 3. Each block 34 is formed or cut to a predetermined height, width and thickness to provide the desired uniform resilient support and padding at the corners of the mattress structure. It is to be noted that with the border strip assembly 24 of the present invention, separate handling of the blocks 34 is eliminated during the mattress assembly process, and the blocks will be automatically properly positioned initially and retained in the proper positions during use of the mattress as a result of being permanently connected with the border strip 30. Another advantage arising from the ease and accuracy of locating the blocks 34 is that less material is required for the blocks since excess material need not be provided to compensate for improper positioning of the blocks or dislodgement of the blocks from their proper positions during use of the mattress.

The border strip assembly 24 also includes one or more handle members 36, only one of which is shown, secured to the strip 39. As will be understood, pairs of the handle members 36 may be secured to the strip 30 in accordance with known practices so that when the border strip assembly is applied to the mattress a pair of the handle members will be located at opposite sides or edges of the mattress. Heretofore, difliculty has been encountered in obtaining proper alignment of the handle members at one side of the mattress with the handle members at the opposite side of the mattress. However, with the border strip assembly 24 of the present invention such alignment of the handle members accom- Patented Mar. 8, 1960 plished easily and automatically when the blocks 34 are properly positioned against the corner Springs since the handle'members are located at predetermined intervals between the blocks; I p r Fig. 7 shows in. detail a; preferred means for securing the blocks 3 4 to the stripStF. More specifically, this means includes a perforated ventilator cap 38 overlying the strip 30' and having a flange 40 connected with a tubular rivetlike member 42 which extends through and is peened over a tightly compressed or pinched portion 44 of'the block 34-. However, it is to be understood that the blocks 34 may be secured to the border strip in various ways such as by sewing, clipping, gluing or the like.

While in the structure described above, only a single block 34 has been disclosed foreach corner of the mattress, it is to be understood that, if desired, a plurality of adjacent disposed blocks may be provided for each cornerof the mattress. Furthermore, Figs. 5- and 6 show a modifiedform of the present invention which is-similar to: the 'a'bove described structure asindicated'by theapplication of identical reference numerals withthe suffix a added to corresponding, elements, and wherein a the 'blocks'34a are preformed or curved. This structure further facilitates proper location'of the blocks with respect to the corner springs of the mattress and further insures the provision ofv properly supported and shaped corners of the mattress. While the preferred embodimentsof the presentiinvenv tionhave been shownand described herein, it isob-vious. that many structural details may be changed without departing from the spirit and scope of the appended claims.
