Description
June 15, 1943;
Filed Nov. 16, 1942 9 I. a 12 11/ 10 15 1 ym 1 H 1 Fig.5. 16 3 .Fjtg.4. F 9'.6.
WlZiamE'l same substantially at right angles to thelongitudinal rows of springs M to insure the mattress or seat being yieldably maintained in proper position at the ends thereof.
Each spring is positioned so that its upper bowed free end 20 normally overlaps the spring in front of it so that when a spring is depressed, it engages the front spring in the manner as shown in dotted lines in Figure 2 to limit the downward movement of the bowed portion thereof. Due to the inherent resiliency of the springs, when the pressure is released, they will return to their normal overlapped position. Thus, simple and efficient means are provided for insuring the continued use of the resilient supporting structure without weakening the resiliency of the springs or distorting them beyond their elastic limits.
Various means may be provided for maintaining the springs M in a fixed position on the frame. As shown in Figures 4 and 5, this means comprises forming the upper surface of each of the longitudinal members II with rabbeted grooves or recesses 21 having a vertical wall 28 for receiving the complementary vertical wall I6 of the triangular base l5 and an inclined notched wall 29 which receives the complementary inclined side I! of the base, so that the bottom [8 of the spring may securely fit within the groove 21. Dowel pins 29 may extend into suitable aligned openings 30 (Figure 5) formed in the base and the member II to assist in securing the springs 14 to the frame. A suitable adhesive may also be applied to the walls of the groove 21 for further assisting in maintaining the springs in a fixed position. Cross beams 3| secured to the upper surface of the members H by screws 32 may be arranged to bear against the vertical side l6 of the base l5 so as to constitute a stop or abutment for maintaining the springs l4 and their associated parts in a fixed position on the frame.
The modification shown in Figure 6 is substantially the same as that shown in Figure 4 with the exception that the cross beam 3| is omitted and the groove 33 is slightly deeper than the groove 21 so that the vertical wall I6 of the triangular base l5 and the inclinedwall l1 firmly engage and abut the corresponding shaped sides of the walls of the groove 33 to maintain the bowed spring 'I 4 securely in position on the member II. A dowel pin 34 may also be arranged to extend through suitable aligned openings in the base [5 and the member H to hold the spring in place.
Thus, it will be seen that a spring frame assembly is provided for supporting bed mattresses, seats, and the like, and which insures the mattress being yieldably maintained at all times in,
proper'position, and which constitutes a comfortable support that will not lose its resiliency when subjected to constant usage.
It will be understood that the forms of the invention shown are merely illustrative of preferred embodiments and that such changes may be made without departing from the spirit of the invention as come within the scope of .the following claims.
