'7 Claims. (Cl. 36-"71) l This invention relates to arch support devices, and more particularly to arch supporting inserts for shoes, slippers or other footwear.
A main object of the invention is to provide a novel and improved arch support device for shoes or other footwear which is very simple in structure, easy to install and adjustable over a wide range of shoe sizes and shapes.
. A further object ofthe invention is to provide an improved arch supporting device which is inexpensive to manufacture,-provides an efficient and comfortable arch supporting action, and which may be installed either during the fabrication of shoes or in completed shoes.
Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein: r
Figure 1 is a topplan view, partly in crosssection, of a shoe provided with an arch supporting device according to the present invention.
Figure 2 is a vertical longitudinal cross-sectional view of the shoe of Figure 1 but showing a modification of the arch supporting structure.
Figure 3 is an enlarged verticaltransverse detail cross-sectional view taken through the sole portion of the shoe of Figure 2.
Figure 4 is a perspective deta'ilview of one of the arch supporting springs employed in the structure of Figure 1.
Figure5 is a perspective detail view of another arch'supporting spring employed in the: structure of Figure 1.
Figure 6 is a perspective detail view of a spring holding bracket employed in the structure of Figure 1.
Figure 7 is other spring holding bracket structure of Figure 2.
Referring to the drawings, H designates a shoe having a bottom sole portion l2 and a superimposed sole portion l3. Secured on bottom sole portion 12 and extending over the shank portion of the shoe are a pair of arched metal springs l4 and I5, each spring being located adjacent a side of the shoe. The forward ends of the springs are received in respective holding brackets l6, l6 fastened to bottom sole portion l2, each bracket [6 comprising a plurality of tabs H for securing it to said bottom sole portion, and a box-like recess portion l8 for receiving the end of an arch spring. One of the brackets I6 is shown in inverted position in Figure 6.
overlying and secured to the rearward ends a perspective detail view of anemployed in the "plate I9. Spring of the arched springs l4 and I5 is a metal heel I4 is formed at its rear end with an inwardly directed portion 20 having an elongated notch 2|. Spring I5 is formed at its rear end with an inwardly directed portion 22 having an elongated notch 23. The rear ends of springs l4 and I5 are secured by respective rivets 24 and 25 joining the respective elements 20 and 22 to the heel plate l9, said rivets passing through the respective notches 2| and 23. The heel plate I9 is secured to bottom sole portion l2 by a rivet 26.
Where the shape of the shoe requires the rear ends of springs l4 and l5 to be closer together than as shown in Figure 1, the rivets 24 and 25 may be omitted and the elements 20 and 22 overlapped with the rivet 26 passing through the aligned notches 2i and 23. The elements 20 and 22 are preferably bevelled so that they may be overlapped and still lie in the same plane.
To reinforce the securement of elements 20 and 22 when theyare overlapped, a bracket 21 is employed having tabs 28, 28 adapted to be se-r cured to heel plate l9, and having a channelshaped intermediate portion 29 adapted to receive the overlapped elements 20 and 22.- The rivet 26 then passes through an opening 30 provided in channel portion 29.
The upper sole portion I3 is superimposed over the springs l4 and I5 and is suitably recessed to accommodate the brackets l6, l6. Said upper sole portion l3 preferably extends rearwardly into overlying relationship with the heel plate l9 so-that the rivet heads 26, 24 and 25 are covered thereby.
In adapting the invention to a completed shoe, the heel of the shoe is removed and an extra bottom sole member is employed, said extra bottom sole corresponding in function to the bottom sole [2. The original bottom sole then corresponds to upper sole member l3 in Figure 2. The extra bottom sole then carries the arched springs and a heel plate such as i9 is secured inside the shoe to the ends 20 and 22 of the springs by rivets, as above described, the rivets passing through the leather at the heel portion of the shoe to engage in the notches 2| and 23 in the alternative manners described above. The extra bottom sole member is then fastened to the original bottom of the shoe by stitching or other suitable means and the heel is replaced.
The arch springs l4 and I5 are fabricated from suitable spring metal such as a bronze alloy containing phosphorus or the like.
While certain specific embodiments of an arch supporting structure for shoes have been disinwardlydirected por-tio rear ends T,Of,.\S@idn1af spring elements to said heel plate.
