Application September 24, 1936, Serial No. 102,296
14 Claims.
The main objects of this invention are:
First, to provide in a spring structure an improved base structure which is very rigid, facilitates the mounting of the springs and also the attachment of the upholstery.
Second, to provide a structure having these advantages which eliminates the necessity for the use of special tools in applying the upholstery and one which permits rapid application of the upholstery by unskilled workmen.
Third, to provide a structure of this type in which the upholstery may be readily removed and reapplied as occasion may require.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
Preferred embodiments of the invention are shown in the accompanying drawings, in which:
Fig. 1 is a fragmentary view partially in elevation and partially in vertical section of a structure embodying the features of the invention.
Fig. 2 is a fragmentary plan view of the spring assembly or unit, parts of the spring being indicated by dotted lines and others shown conventionally in full lines.
Fig. 3 is a fragmentary view in horizontal section on line 3-3 of Fig. 1. V
Fig. 4 is a fragmentary bottom perspective view of the border frame.
Fig. 5 is a fragmentary perspective view illustrating the relation of the border frame members and the spring supporting grid.
Fig. 6 is a fragmentary perspective view of a slightly modified form or embodiment of the border frame.
Fig. '7 is a fragmentary perspective view illustrating another modification or embodiment.
Referring to the .drawings, reference numeral I indicates generally the border frame made up of side members 2, 2 and end members 3, 3. The embodiment illustrated is substantially of rectangular cross section, the form shown being for convenience in illustration but it will be understood that in practice the frames are shaped to meet the particular requirements.
In this embodiment, the side and end members are formed separately and joined by corner irons 4 which are secured by means of spot welds 5. These border or frame members are formed of strips of sheet metal folded or conformed longitudinally to provide a rounded bight 6 preferably enclosing a reinforcing rod or wire 1. The arms above the bight are disposed side by side provide an upstanding web 8. The inner arm terminates in a horizontally disposed flange or ledge 9 having tongues iii struck downwardly therefrom, these tongues being preferably A'- shaped to provide an eye for piercing the uphclstery as will be described. The outer arm of folded strip terminates in an outwardly offset inwardly facing spring supporting channel 5 l which is spaced from the bottom bight 6 of the frame so that it may be engaged with a plier-like tool to clamp the upper flange of the channel l2 upon bottom coil of a spring l3 as is shown at it in the drawings.
To support the body springs and to brace and make the frame rigid, I provide cross bars 15 which are lapped upon and welded to the flange or ledge 9 at l6, and. I also provide a spring supporting grid of crossed wires I1 and IS, the ends of these grid wires being lapped uponand welded to the flange or ledge 9 as indicated at IS. The springs are secured to this grid by means of clips indicated at 29.
In the embodiment shown in Fig. 6, the upholstery securing members 24 are turned downwardly and designed to clamp the bead or edge of the upholstery skirt against the web portion of the frame. I
In the embodiment of myinvention shown in Fig. '7, the strip is folded to provide a double thickness spring receiving channel 25, the supporting ledge 2% extending from this channel, the other edge of the strip being conformed to provide an outwardly facing upholstery securing channel 2's, the Shirt 25 of the upholstery being arranged therein and secured by clamping the flange 29 of the channel upon the skirt as is indicated at 38. This also provides an effective means for securing the upholstery, rendering the upholstery operation practical with the use of unskilled labor, and the structure is very rigid so that it withstands severe usage and is suitable for heavy work.
I have illustrated and described embodiments of my invention which I consider very practical. I have not attempted to illustrate or describe certain other embodiments or adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
