$2 2570 lzurom United States Patent ADJUSTABLE SHOE Anton Seurbom, Chicago, Ill.

Application April 23, 1953, Serial No. 350,660

11 Claims. (Cl. 36--2.5)

This invention relates to shoe constructions, and more particularly to adjustable shoes.

My invention is concerned primarily with shoes adapted for use by manikins. It is well known that the feet'of manikins are stiff and therefore it is difficult, if not impossible, to fit ordinary shoes over them. Moreover, it has been very difiicult for a single decorator to put shoes on a manikin operating by himself in a confined store window area. For this reason, shoes once placed on a Inanikin are usually left on, regardless of the change in season or the attire of the manikin. Needless to say, shoes left on a manikin are subject to deterioration due to overexposure to sunlight and gradually lose their attractive appearance.

it is therefore an object of my invention to provide a shoe that can be more readily fitted to a manikins foot than any heretofore known.

As a rule there is no standard foot size for manikins, and therefore it is necessary to provide shoes of different sizes for them. This requires the stocking of various sizes of shoes which is an item of considerable expense .in the upkeep of a manikin.

it is an object of my invention to provide a shoe that 'will fit any size of foot, thereby eliminating the purchasing of different size shoes for each manikin.

I have noted that one of the difiiculties of placing shoes on manikins is that the type of shoes now used or shown in the prior art requires the use of two hands and even then is difiicult to manage. My invention eliminates this difficulty by providing a simple locking device that requires the use of only one hand of the decorator.

.ln manikin shoes it is unnecessary to have the shoe fit perfectly, but it is of the utmost importance that the shoe appear to fit perfectly. I have found that a manikin shoe .appears to fit perfectly if it fits tightly across the instep or arch of the foot. Accordingly, an object of my invention is to provide a manikin shoe that fits perfectly across the {instep or arch, thereby giving the appearance of a per- ;fect fit.

It is a further object of my invention to provide shoes .for manikins that may be easily assembled by a single decorator working in a confined area.

It is a further object of my invention to provide shoes that may be very economically constructed.

It is also contemplated to provide shoes of diiferent .colors and adapted for different types of attire and proper for each season.

The present invention lends itself to a simple arrangement whereby the toe section of the shoe is adjustable laterally, thereby providing for a perfect fit across the instep of the manikin, and for longitudinal association between the toe and heel sections whereby the heel is 'bayonetted into the toe section and secured against longitudinal displacement.

In my invention I contemplate securing the parts tosgether by the use of a dead center locking device which facilitates rapid one hand assembly of a shoe on the foot .of a manikin.

2,734,284 Patented Feb. 14, 1956 ice My invention is adapted to any type of shoe, including low heels, high heels, boudoir slippers, mules, elevator soles, etc.

The foregoing and other objects will be more apparent from the following detailed description when considered in connection with the accompanying drawings, wherein:

Fig. l is a perspective view of the shoe construction contemplated by the present invention;

Fig. 2 is a fragmentary top plan view showing the means whereby longitudinal and lateral adjustment of the shoe construction is made possible;

Fig. 3 is a sectional view taken along the line 3--3 of Fig. 2;

Fig. 4 is an exploded perspective view of my invention;

Fig. 5 is a fragmentary sectional view taken along the line 55 of Fig. 2, and showing the shoe assembled;

Fig. 6 shows an alternative clamping means for securing the parts against longitudinal and lateral displacement.

Referring now to the drawings .more in detail, wherein like numerals have been employed to designate similar parts throughout the figures, it will be seen that my shoe construction consists of a heel covering member or quarter portion 8 and a toe or toe-covering member or portion 10. The heel and toe portions may be made of any suitable material such as leather, cloth, plastic, papier mache, or artificial leather. The sole i2 is sewn, glued, or otherwise attached to the toe portion it), and a heel elevation member 14 is affixed to the heel covering portion 8 by any suitable means such as sewing, gluing, stapling or nailing. Between the heel elevation member 14 and the heel covering portion 8 is an insole l6 affixed to the heel portion and heel elevation member by any suitable means.

in my invention, the toe portion 10 and the heel portion 8 are made separately and are assembled on the foot 18 of a manikin by bayonetting them together. The heel and toe portions are secured against longitudinal displacement by a fastening means 20.

Referring now to Fig. 4, it will be seen that the sole 12 is made of two layers of material, 22 and 24. Any suitable material may be used, such as leather, cardboard, plastic, papier mache, or artificial leather. The layer 24 comprises the outer sole of the toe portion and layer 22 comprises the insole of the toe portion. These portions are secured together as at 26 by sewing, gluing, stapling or nailing.

It will be noted that the outer sole 24 is provided with an opening having transverse edges 28 and 30 at the be ginning of the instep, and these transverse edges extend from the outer extremities of the shoe to points 32 and 34. From the points 32 and 34 the opening in the outer sole is provided with longitudinal edges 35 and 37 to form a strap portion 36. The strap is apertured at 38 for a purpose to be presently described.

The insole portion 22 overlies the outer sole 24 and the toe covering member ill is sewn or otherwise attached therebetween. The insole portion 22 is provided with a transverse edge 40 which is parallel to and spaced a bit forwardly of the transverse edges 28 and 30 of the outersole 24.

Extending from the insole in the direction of the heel are transverse adjustable arms 42 and 44. These arms are made of any suitable stiff material, suchras cardboard, leather or artificial leather. The outer marginal portions of arms 42 and 44 correspond to the outer configuration of the shoe. The inner margin of the arm 42, starting at the outer extremity of edge 40, is provided with a diagonal edge 45 extending toward the center of the shoe, which may be at an angle of approximately forty-five degrees to the outer margin. Diagonal edge 46 forms the next section of the inner margin and extends towards the outer margin forming an angle which may be approximately ninety degrees with diagonal edge 45. A

third diagonal edge 48 is provided which extends inwardly from the outer end of edge 46, this edge forming an angle which may be approximately ninety degrees with diagonal edge 46. The final edge 50 of arm 42 extends from the extremity of edge 48 in a curve back to the outer margin of the shoe. Ann 42 is further provided with a rectangular hole 52. This elongated rectangular hole 52 is placed at an angle which may be approximately forty degrees to edge 48, and runs between edge 43 and edge 50. As is shown in Fig. 4, arm 44 is formed in a manner similar to arm 42 and is provided with rectangular hole 53.

The toe cap portion is glued, sewn, or otherwise attached to the top surface of arms 42 and 44.

The purpose of the various edges is to permit the trans verse adjustment of the toe portion of the shoe, thereby permitting convenient application of the toe portion to the foot of a manikin, and thereafter adjusting the arms 42 and 44 to give a perfect fit of the shoe in the region of the manikins instep.

As will appear presently, the elongated rectangular openings cooperate with other parts to secure the arms 42 and 44 against lateral displacement.

Referring now to the heel portion, the heel insole 54 has an outer margin corresponding to the configuration of the heel. The heel insole covers the area over the heel elevation member 14, and the leather or fabric covering the foot is sewn, glued, or otherwise attached between the insole 54 and the heel elevation member 14.

The portion of the heel insole 54 over the instep 56 is provided with transverse edges 58 and 6t). Edges 62 and 64 extend toward the heel section and are disposed at an angle which may be approximately one hundred degrees to edges 58 and 60. Edges 66 and 68 extend from the ends of edges 62 and 64 and form an angle which may be approximately one hundred and twenty degrees therewith. Edges 66 and 68 extend clear to the margin of the shoe and as Will be seen allow a bending of the heel fabric 8 to conform with the shape of a manikin foot. Finally, edges 70 and 72 are provided to complete the inner margin of the heel insole 54. Edges 70 and 72 describe an angle which may be approximately fortyfive degrees with edges 66 and 68. It is to be noted that edges 62 and 64 are substantially parallel when the heel is aflixed to the foot of a manikin, but this position may be varied depending on the size of the manikins foot. Having described the edges in the instep or shank portion 56 specifically, the areas so described may be referred to more generally as projections in the form of tabs or arms 74 and 76, whose function will presently be described.

The assembly of the heel and toe sections is effected by the use of a washer 78 and a fastener locking device 80. The fastener locking device 80 is composed of a piece of sheet metal 84 bent intermediate its ends, with a hole 86 on one end 87 adjacent the bend, and a cut out portion 88 on the other end 89 adjacent the bend. A cotter pin 90 is inserted over the bend with one arm of the cotter pin extending through the aperture 86 and the other through the cut away portion 88.

Substantially all of the parts of my invention having been described, there remains to be described the manner in which they are assembled. The assembly of the parts is best shown in Fig. 2 wherein they are shown in assembled relationship. The parts are first loosely assembled by partially bayonetting the projections in the form of tabs or arms 74 and 76 of the heel portion beneath the washer 78 in the toe assembly. The arms 42 and 44 of the toe assembly are spread laterally to permit easy access of the heel portion into a position in which inserts 74 and 76 underlie washer 78.

As shown in Figs. 2, 3 and 5, cotter pin 90 is first passed through the hole 38 in the strap 36, and then passes through the elongated rectangular slot 52.01; arm 42. Arm 42 is placed over arm 44 in such a manner that they overlap, and the cotter pin is then inserted into the elongated rectangular slot 53 of arm 44. At this point in the assembly, the washer 78 is loosely fitted over the cotter pin 9:) and the arms of the cotter pin are spread. It should be noted that the arms of the cotter pin are not spread in such a manner as to tightly hold the elements together, but loosely so as to permit free movement of the arms 42 and 44 relative to the strap 36, and to provide for the assembly of projections in the form of tabs or arms 74 and 76 therewith.

The loosely assembled shoe is then placed over the foot 18 of a manikin. To complete the assembly, the heel portion is further longitudinally bayonetted into the toe portion until a perfect longitudinal fitting is obtained. At this point the projections in the form of tabs or arms 74 and 7e are pressed inwardly, thereby obtaining a snug fit over the heel and upper instep portion of the manikin. The arms 42 and 44 of the toe portion are then pressed inwardly, as provided for by the elongated rectangular apertures 52 and 53, to obtain a perfect fit of the shoe over the toe and lower instep portion. The shoe is now perfectly fitted, or appears to be perfectly fitted to the foot of the manikin, and there remains only the securing of the parts in such a manner as to prevent longitudinal and lateral movement of the parts so assembled.

Referring to Fig. 5, the securing of the parts against longitudinal and transverse movement is accomplished by swinging the free end 37 of the fastener locking device 80 from the dash line position of Fig. 5 past dead center to the full line position, thereby bringing the end 89 into contact with the shoe and pressing the parts together. The free end 3'7 is swung through an are which may be approximately one hundred and sixty degrees, and the end 39 is thereby moved over the sole until the cut away portion 88 is slightly beyond dead center of the aperture 38 and the locking completed.

Fig. 6 shows another form of fastening or locking device which may be used with my invention. Washers 92 and 94 are placed on the outer and inner sides of the layers to be locked together. Washer 96 is a spring steel convex washer superimposed over the lower Washer 94. A handle 98 is apertured near one end thereof, and cut out at the extreme end thereof, leaving a bar of metal between the aperture and cut out end portion. A resilient metal strap 99 is positioned in such a way that one arm passes through the aperture in the handle and the other arm passes through the cut out portion. Both arms of the metal strap are then passed through the washers and separated as at 100, 102, 104 and 106.

The bends and N2 in metal strap 99 provide the locking function in the device and the ends 1&4 and 106 are spread for the purpose of clearing the arch of the manikins foot. The device is locked by moving one end of the handle 98 through an are, thereby spreading the arms of the metal strap 99, and forcing the other end of the handle against the convex spring steel washer 96, which action presses the work pieces together. When the handle engaging the washer 96 passes dead center the spring is released and the device is locked.

Having described the parts and operation of my invention it will be seen that it provides a means for longitudinal and transverse adjustment of a shoe to fit any foot and to provide a perfect fit thereon.

The dead center locking device of my invention provides for rapid one hand assembling of a shoe on the foot of a manikin. A decorator working by himself in a confined area can readily assemble the shoe with one hand.

My shoe is economical to produce and can be made from a variety of materials.

My invention is also adapted for shoes in which there is a toe portion and sole portion only, such as mules and boudoir slippers.

While I have described a specific constructional embodiment of my invention, it is obvious that desired changes in the shape and material of the parts and in their relative arrangement may be made to suit the requirements of different shoe designs and uses within the spirit and scope of my invention.
