Definitions
- This invention relates to a new and improved sanitary shoe wrapper. More particularly, the invention relates to a wrapper fitting around the shoe of the wearer for sanitary and safety precautions primarily for use in hospitals, industrial and commercial installations, and the like, wherein the problem of contamination of the atmosphere or the floor from dirt on shoes is to be avoided. Conversely the wrapping may protect the shoes from the atmosphere or dirt on the floor.
- the wrapper is made either Wholly or partially of electrically conductive material and is further so constructed as to provide for contact of a portion of the conductive material with the skin of the wearer. In this manner, charges of static electricity may be grounded to reduce danger of explosion.
- the wrapping is disposable so that it may be used once, or a few times, and discarded.
- An important use of the present invention is to provide a wrapping for the shoes of surgeons and other hospital operating room personnel. For the purpose of maintaining cleanliness in the operating room, it is desirable that dirt on the shoes be prevented from reaching the patient, a function which the wrapper of the present invention performs effectively. Another problem in such use is to prevent charges of static electricity from igniting anesthetic and other explosive atmospheres which may be present in the operating room.
- the present invention provides a means for skin contact of the surgeon, and a further means for grounding the contact to the floor. It will be understood that some industrial and commercial installations have similar problems, such as where there are explosive materials, such as paint, pharmaceuticals, and the like.
- Show window dressers conventionally remove the shoes, or place a covering over the shoes, so that the floor of the show-window is not marked by dirt on the shoes of the dresser.
- the present invention provides a wrapper to accomplish the same result.
- the present invention provides a simple wrapping for the shoe as distinguished from prior coverings, the wrap ping being uniquely designed.
- a further feature of the invention is the fact that its simple construction does not require separate wrapping for right and left feet, but a single wrapping will fit either foot. Additionally, the device is adjustable for size of the shoe over vavery wide range, thereby reducing the in- United States Patent Patented Aug. 22, 1967 ventory or stock of wrappings which must be maintained to fit different shoe sizes.
- a further advantage of the invention is the fact that it is so constructed that it can be applied to the shoe conveniently with little time or effort consumed.
- the construction of the device is such that unskilled users cannot through misapplication of the device fasten the same on the shoe in an improper manner.
- Another feature of the invention is the fact that it is possible to use very low cost material in certain versions of the device with the result that the wrapping is inexpensive and is disposable.
- Still another feature of the invention is the fact that its manufacture is economical in use of material by reason of inter-fitting of the patterns in a web of material and the manufacture of the completed device may be to a large extent automated.

- FIG. 17 is a fragmentary perspective view of the heel portion partially broken away to reveal construction.
- the present invention provides a wrapping of a sanitary or non-contaminating nature of simple and inexpensive construction.
- the body of the device may be formed of a wide variety of materials.
- Non-woven materials such as paper or yarn-reinforced cellulose material, and nonwoven fabrics are particularly suitable for the present invention, such materials being received from their manufacturer in webs or rolls of extended widths and lengths from which a plurality of blanks may be interfitted with economy of material.
- Cloth such as light canvas, muslin, or almost any fabric may be used to construct the device.
- Plastics may be used, depending upon the end use of the wrapper.
- the entire device may -be formed of a conductive material.
- a strip is sewn, glued, stapled or otherwise attached to the wrapping and is formed of a conductive material.
- a preferred conductive material is a conductive polyolefin of a thickness of two to three mils, one such product being known as valostat manufactured by Custom Materials, Inc. of Chelrnsford, Mass. Aluminum foil tape is also suitable.
- blank 11 has forwardly converging front edges 12 meeting at a point 13 at the front. Edges 12 extend about half the length of the blank 4. Rearwardly thereof are substantially parallel rearward extending side edges 14. Oblique rear edges 16 extend inward from the rearward ends of sides 14 to a central rear tongue 17, formed with parallel rearward extending side edges 18 and a rear end 19.
- the blank 11, illustrated in FIG. 1, is particularly advantageous because of its economical use of material.
- a plurality of blanks 11a may be placed with side edges 14 adjacent and with points 13, all in the. same direction. Inter-fitting between points 13 of blanks 11a are the corresponding points of blanks 11b, which are in reverse direction.
- Blanks 11c on the opposite end of blanks 11a are turned in the same direction as blanks 111), but tongues 17 of these blanks are staggered between tongues 17 of blanks 11a. Only small trapezoidal pieces 20 between tongues 17 are scrap.
- the number of blanks which may be cut from a web of material is only dependent upon the width and length of the web, only a fragment thereof being shown in FIG. 2.
- the individual blanks may be cut from the web by various means. Die cutting is one means of forming the individual blanks. Alternatively, layers of webs may be cut, as well understood in the garment industry. The waste of material in this arrangement of the blank is quite insignificant.
- a narrow tape 21 may be sewn to the blank 11, extending longitudinally of the blank from a point adjacent the end 13 medially of the blank to the heel portion 17, and extending beyond end 19 in a tongue 22 of extended length.
- the material of which the tape 21 is formed has heretofore been described.
- the tape may be applied to blank 11 by means of stitching 23, as illustrated, or may be applied by various adhesives, or staples or other attachment, or may be heat adhering.
- Ties 26 are applied to the blank 11, extending generally transversely of the blank. In the form shown in FIGS. 3 and 4, ties 26 are secured only at the center of the bottom of the wrapping.
- ties 26 are adhered to the blank partially up the sides by means of stitching '7, glue, stapling, or other means of attachment.
- the ties 26 are of extended length so that they may be knotted to hold the wrapping on the shoe when it is in use (FIG. 4).
- Assembly of the wrapping to form the heel portion 31 may be accomplished by gluing adjacent edges 16 and 18 together in a seam 32, or by means of stitching or other attachment means, thereby providing a box-like heel of a width substantially equal to that of tongue 17.
- the device With the completion of this operation, the device is in shape for shipment from the factory. It may be folded for compactness, or pluralities of wrappings may be nested together.
- the heel 33 of the shoe is positioned nesting into the heel 31 of the wrapping.
- the point 13 is folded up over the instep of the shoe, the distance which the point is folded back being determined by the length of the shoe 34- of the wearer.
- the sides 36 on either side making up the fullness of blank 11 are folded over, one side over the other.
- Ties 26 are brought together and formed in a knot 37 over the instep.
- the sides 36 may be folded inwardly first and tip 13 folded back and held on by ties 26.
- the extended length of conductive material 22 may be tucked into the upper end 38 of the sock of the wearer to establish skin contact of the tab 39 on the end of the conductive tape. Since the tape 21 extends down the back of the heel 31 to the bottom of the wrapping, electrical contact with the floor is achieved.
- the device may be installed rapidly and likewise removed rapidly.
- the shoes of the wearer are covered so that dirt on the shoes does not contaminate the surrounding atmosphere or floor covering. Alternatively, if the surrounding atmosphere is contaminated, the shoes are not contaminated. Where conductive material is used, the body of the wearer is grounded.
- the device After use, the device may be discarded if its cost is not a prime consideration. However, where the device is constructed in a substantial manner, it may be reused and even laundered between uses.
- blank 41 has forwardly converging front edges 42 meeting at a front point 43. Edges 42 extend about half the length of the blank and the front point is approximately an equilateral triangle. Side edges 44 are about parallel to each other. Rear end 49 is square and of a width about two-thirds the overall width of the blank and about three times the eventual heel width. Each corner is formed with perpendicular longitudinal and transverse cuts 46, 48 of equal length. How pluralities of blanks interfit to conserve material is illustrated in FIG. 6. Only square pieces 50 are scrap.
- Narrow longitudinally extending conductive tape 51 is adhered, glued, sewn, stapled or otherwise attached to blank 41 as by stitching 53, preferably commencing at a point spaced back from point 43 and continuing beyond end 49 in an extended tongue 52.
- Transverse tape ties 56 are preferably formed of a unitary piece of material under tape 51 and tacked by tacks 57 of glue or stitching partially up the sides, so that the extended lengths of ties are conveniently at hand when the covering is to be tied in place.
- diagonal folds 62 are formed on either side extending inward at about 45 from the intersection of cuts 46, 48, to a point 63.
- Longitudinal folds 64 extend rearward from point 63 to end 49 and transverse folds 66 from point 63 to side edge 44.
- the material is folded inward and overlapped as shown in FIGS. 7 and 8.
- Horizontal transverse stitching 67 across the top of the heel 61 holds the folds in assembled position, as best shown in FIG. 9.
- Longitudinally forwardly converging bends 68 extend from points 63 to point 42 and transverse bend 69 interconnects points 63 at the heel.
- a partial toe may be formed.
- short stretches of front edges 42 are joined together as by stitching 71, cement or glue, staples or other means of attachment.

- the toe is folded forward and the sides up and over and ties 56 applied substantially as shown in FIG. 4 of the preceding modification.
- Tongue 52 is tucked into the sock as previously explained.
- FIGS. 1 to 4 The materials of construction in the modification of FIGS. 1 to 4 are the same as for corresponding parts of the form described with reference to FIGS. to 10, as well as the further modification of FIGS. 11 to 14 which follows.
- blank 81 has forwardly converging front edges 82 meeting at front point 83.
- Side edges 84 converge rearwardly, but are close to parallel.
- Rear end 89 is square and of a width about one-half the maximum width of the blank but approximately three times the assembled heel width.
- Each corner is formed by a generally transverse but rearwardly slanted cut 88 extending inwardly from the back end of side 84 and a generally longitudinal but inward-rearward slanting cut 86 which interconnects end 89 and cut 88; cuts 86 and 88 are of about equal length.
- Conductive tape 81 is adhered, glued, sewn, stapled, or otherwise attached, to blank 81 as by stitching 93, preferably commencing at a point spaced back from point 83 and extending beyond end 89 in an extended tongue 92.
- Transverse tape ties 96 are formed of a unitary piece of material under tape 91 and tacked by glue at locations indicated by reference numeral 97 or adhered by other means, as in the preceding modification.
- FIGS. 12 and 13 the front edges of the sides are partially overlapped adjacent point 83 and held with adhesive 111.
- FIG. 14 illustrates a still further modification of the structure of FIGS. 11 to 131 Stitching 93 is eliminated and a wire staple 112 used to hold the folds in assembled position.
- Blank 121 has forwardly-converging front edges 122 meeting at a point 123 at the front. Edges 122 eX- tend about half the length of blank 121. Rearwardly thereof are slightly rearwardly-converging but substantially parallel rearwardly-extending side edges 124. Rear edges 1.26 extend obliquely, although almost transversely, inward to meet at the center. In this form of the invention, a tongue, corresponding to tongue 17 of FIG. 1, is not used. Hence the overall length of the blank is less than in previous forms described.
- Tape 127 is sewn, glued or otherwise adhered to blank 121 commencing at about the middle of the blank and extending rearwardly and projecting beyond the rearward edges 126 in an extended tab 128.
- tape 127 is sewn to blank 121 only about to position 129.
- Ties 131 consist of a single transverse length of material considerably wider than the blank which underlies tape 127 and is stitched or otherwise adhered to the blank by the same means as tape 127.
- Bar tacks 132 may be used, as in previous forms.
- the rearward corners 133 at the juncture of edges 124, 126 are folded diagonally inward toward the center of the blank along fold lines 134 so that the corners 133 slightly overlap at the center.
- Lines 134 intersect edges 124 about one-quarter of the length thereof rearward of intersection with edges 122 and cross immediately forward of the center of the rear end of the blank. Which corner 133 underlies the other is immaterial.
- the rear end of the blank is triangular having a rear apex at 136.
- the next step in assembly is to fold apex 136 forward along transverse fold line 137 which has a length equal to the eventual width of the heel.
- Stitching or other adhering of tape 127 rearward of position 129 is then completed and this operation secures folds 13 4, 137 in permanent relation.
- the wrapping is turned inside out, as shown in FIG. 16, so that apex 136 is inside rather than outside.
- the heel forms along parallel folds 138 transverse to fold 137 and said folds continue longitudinaly along the bottom in folds 139.
- a sanitary and protective covering wrapping for a conventional shoe inserted in said wrapping comprising an elongated body of a single layer of highly flexible, paperlike, foldable and disposable material, having front edges converging forward toward a point at the front, substantially longitudinal side edges and a heel portion at the rear of lesser width than the distance between said side edges, said body shaped to conform generally to the shape of the sole, heel, toe, instep and sides of said conventional shoe and formed with sole, side and back portions, said side and back portions erected upright relative to said sole portion to define a heel pocket at one end to receive the heel of said conventional shoe, means permanently securing said back to said sides to maintain said heel pocket, said body having a longitudinally extending toe forming portion at the end opposite said heel pocket, said toe forming portion flexible to enable said toe forming portion to be drawn up over the instep of the wearer to seat said heel in said heel pocket and then to conform said wrapping snugly to the length of said shoe and means on said body engaging the drawn up part of said toe

SANITARY SHOE-WRAPPER Filed April 13, 1964 4 Sheets-Sheet 4 INVENTORS JOSEPH SARA CEN/ HAROLD Z/MMON ATTOENE Y Calif.
Filed Apr. 13, 1964, Ser. No. 359,356 10 (Iiaims. (Cl. 317-2) This invention relates to a new and improved sanitary shoe wrapper. More particularly, the invention relates to a wrapper fitting around the shoe of the wearer for sanitary and safety precautions primarily for use in hospitals, industrial and commercial installations, and the like, wherein the problem of contamination of the atmosphere or the floor from dirt on shoes is to be avoided. Conversely the wrapping may protect the shoes from the atmosphere or dirt on the floor.
In a preferred embodiment of the present invention, the wrapper is made either Wholly or partially of electrically conductive material and is further so constructed as to provide for contact of a portion of the conductive material with the skin of the wearer. In this manner, charges of static electricity may be grounded to reduce danger of explosion.
In a still another preferred embodiment of the invention, the wrapping is disposable so that it may be used once, or a few times, and discarded.
An important use of the present invention is to provide a wrapping for the shoes of surgeons and other hospital operating room personnel. For the purpose of maintaining cleanliness in the operating room, it is desirable that dirt on the shoes be prevented from reaching the patient, a function which the wrapper of the present invention performs effectively. Another problem in such use is to prevent charges of static electricity from igniting anesthetic and other explosive atmospheres which may be present in the operating room. The present invention provides a means for skin contact of the surgeon, and a further means for grounding the contact to the floor. It will be understood that some industrial and commercial installations have similar problems, such as where there are explosive materials, such as paint, pharmaceuticals, and the like.
Show window dressers conventionally remove the shoes, or place a covering over the shoes, so that the floor of the show-window is not marked by dirt on the shoes of the dresser. The present invention provides a wrapper to accomplish the same result.
Heretofore, most devices for the foregoing purposes have been of a slipper, shoe or boot-shape, in that they are formed with more or less conventional heels and toes. The present invention is not conventional in the formation of the toe, which simplifies manufacture and makes the device less expensive.
By reason of the low expense in manufacturing the present invention, which is occasioned at least in part by the elimination of conventional heels and toes, there is provided a low priced protective covering for the shoe. Thus the present invention provides a simple wrapping for the shoe as distinguished from prior coverings, the wrap ping being uniquely designed.
Because of the simplicity of design and low cost of manufacture, it is possible to provide an efficient conductive or non-conductive wrapping for the shoes of great value which can be made so cheaply as to be disposable, thereby eliminating the laundry or cleaning problems of prior devices for the same purposes.
A further feature of the invention is the fact that its simple construction does not require separate wrapping for right and left feet, but a single wrapping will fit either foot. Additionally, the device is adjustable for size of the shoe over vavery wide range, thereby reducing the in- United States Patent Patented Aug. 22, 1967 ventory or stock of wrappings which must be maintained to fit different shoe sizes.
A further advantage of the invention is the fact that it is so constructed that it can be applied to the shoe conveniently with little time or effort consumed. The construction of the device is such that unskilled users cannot through misapplication of the device fasten the same on the shoe in an improper manner.
Another feature of the invention is the fact that it is possible to use very low cost material in certain versions of the device with the result that the wrapping is inexpensive and is disposable.
Still another feature of the invention is the fact that its manufacture is economical in use of material by reason of inter-fitting of the patterns in a web of material and the manufacture of the completed device may be to a large extent automated.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.
In the drawings:
FIG. 1 is a plan view of a blank or pattern for the device, in accordance with the invention.

FIG. 17 is a fragmentary perspective view of the heel portion partially broken away to reveal construction.
The present invention provides a wrapping of a sanitary or non-contaminating nature of simple and inexpensive construction. The body of the device may be formed of a wide variety of materials. Non-woven materials, such as paper or yarn-reinforced cellulose material, and nonwoven fabrics are particularly suitable for the present invention, such materials being received from their manufacturer in webs or rolls of extended widths and lengths from which a plurality of blanks may be interfitted with economy of material. Cloth, such as light canvas, muslin, or almost any fabric may be used to construct the device.
Plastics may be used, depending upon the end use of the wrapper.
In many of the installations, as has heretofore been explained, where such coverings may be used, it is desirable to ground the wearer to the floor. For such purpose, the entire device may -be formed of a conductive material. Alternatively, as shown in the accompanying drawings, a strip is sewn, glued, stapled or otherwise attached to the wrapping and is formed of a conductive material. A preferred conductive material is a conductive polyolefin of a thickness of two to three mils, one such product being known as valostat manufactured by Custom Materials, Inc. of Chelrnsford, Mass. Aluminum foil tape is also suitable.
Turning to the accompanying drawings in the form shown in FIGS. 1 to 4, blank 11 has forwardly converging front edges 12 meeting at a point 13 at the front. Edges 12 extend about half the length of the blank 4. Rearwardly thereof are substantially parallel rearward extending side edges 14. Oblique rear edges 16 extend inward from the rearward ends of sides 14 to a central rear tongue 17, formed with parallel rearward extending side edges 18 and a rear end 19. The blank 11, illustrated in FIG. 1, is particularly advantageous because of its economical use of material. As best shown in FIG. 2, a plurality of blanks 11a may be placed with side edges 14 adjacent and with points 13, all in the. same direction. Inter-fitting between points 13 of blanks 11a are the corresponding points of blanks 11b, which are in reverse direction. Blanks 11c on the opposite end of blanks 11a are turned in the same direction as blanks 111), but tongues 17 of these blanks are staggered between tongues 17 of blanks 11a. Only small trapezoidal pieces 20 between tongues 17 are scrap. The number of blanks which may be cut from a web of material is only dependent upon the width and length of the web, only a fragment thereof being shown in FIG. 2. The individual blanks may be cut from the web by various means. Die cutting is one means of forming the individual blanks. Alternatively, layers of webs may be cut, as well understood in the garment industry. The waste of material in this arrangement of the blank is quite insignificant.
Where conductivity is of importance, as in end uses where an explosive atmosphere prevails, a narrow tape 21 may be sewn to the blank 11, extending longitudinally of the blank from a point adjacent the end 13 medially of the blank to the heel portion 17, and extending beyond end 19 in a tongue 22 of extended length. The material of which the tape 21 is formed has heretofore been described. The tape may be applied to blank 11 by means of stitching 23, as illustrated, or may be applied by various adhesives, or staples or other attachment, or may be heat adhering. Ties 26 are applied to the blank 11, extending generally transversely of the blank. In the form shown in FIGS. 3 and 4, ties 26 are secured only at the center of the bottom of the wrapping. In other modifications, ties 26 are adhered to the blank partially up the sides by means of stitching '7, glue, stapling, or other means of attachment. The ties 26 are of extended length so that they may be knotted to hold the wrapping on the shoe when it is in use (FIG. 4).
Assembly of the wrapping to form the heel portion 31 may be accomplished by gluing adjacent edges 16 and 18 together in a seam 32, or by means of stitching or other attachment means, thereby providing a box-like heel of a width substantially equal to that of tongue 17. With the completion of this operation, the device is in shape for shipment from the factory. It may be folded for compactness, or pluralities of wrappings may be nested together.
In use, the heel 33 of the shoe is positioned nesting into the heel 31 of the wrapping. The point 13 is folded up over the instep of the shoe, the distance which the point is folded back being determined by the length of the shoe 34- of the wearer. Thereupon, the sides 36 on either side making up the fullness of blank 11 are folded over, one side over the other. Ties 26 are brought together and formed in a knot 37 over the instep. Although the foregoing sequence is preferable, nevertheless, it is apparent that the sides 36 may be folded inwardly first and tip 13 folded back and held on by ties 26. The extended length of conductive material 22 may be tucked into the upper end 38 of the sock of the wearer to establish skin contact of the tab 39 on the end of the conductive tape. Since the tape 21 extends down the back of the heel 31 to the bottom of the wrapping, electrical contact with the floor is achieved.
It is apparent from the foregoing description, that the device may be installed rapidly and likewise removed rapidly. The shoes of the wearer are covered so that dirt on the shoes does not contaminate the surrounding atmosphere or floor covering. Alternatively, if the surrounding atmosphere is contaminated, the shoes are not contaminated. Where conductive material is used, the body of the wearer is grounded.
After use, the device may be discarded if its cost is not a prime consideration. However, where the device is constructed in a substantial manner, it may be reused and even laundered between uses.
In the form of the invention shown in FIGS. 5 to 9, blank 41 has forwardly converging front edges 42 meeting at a front point 43. Edges 42 extend about half the length of the blank and the front point is approximately an equilateral triangle. Side edges 44 are about parallel to each other. Rear end 49 is square and of a width about two-thirds the overall width of the blank and about three times the eventual heel width. Each corner is formed with perpendicular longitudinal and transverse cuts 46, 48 of equal length. How pluralities of blanks interfit to conserve material is illustrated in FIG. 6. Only square pieces 50 are scrap.
Narrow longitudinally extending conductive tape 51 is adhered, glued, sewn, stapled or otherwise attached to blank 41 as by stitching 53, preferably commencing at a point spaced back from point 43 and continuing beyond end 49 in an extended tongue 52. Transverse tape ties 56 are preferably formed of a unitary piece of material under tape 51 and tacked by tacks 57 of glue or stitching partially up the sides, so that the extended lengths of ties are conveniently at hand when the covering is to be tied in place.
In assembling the wrapping to form heel 61, diagonal folds 62 are formed on either side extending inward at about 45 from the intersection of cuts 46, 48, to a point 63. Longitudinal folds 64 extend rearward from point 63 to end 49 and transverse folds 66 from point 63 to side edge 44. The material is folded inward and overlapped as shown in FIGS. 7 and 8. Horizontal transverse stitching 67 across the top of the heel 61 holds the folds in assembled position, as best shown in FIG. 9. Longitudinally forwardly converging bends 68 extend from points 63 to point 42 and transverse bend 69 interconnects points 63 at the heel.
As an optional feature of the invention, to facilitate insertion of the toe of the shoe in the wrapper, a partial toe may be formed. Thus in FIG. 8a, short stretches of front edges 42 are joined together as by stitching 71, cement or glue, staples or other means of attachment.
As shown in FIG. 10, front edges 42 are partially overlapped and a transverse tack 72 applied to hold the toe together. Tack 72 may likewise be by stitching, gluing, stapling, or other means of attachment.
In either of the forms of FIGS. 8 and 10, the shoe toe is first inserted and then the heel. The toe is folded forward and the sides up and over and ties 56 applied substantially as shown in FIG. 4 of the preceding modification. Tongue 52 is tucked into the sock as previously explained.
The materials of construction in the modification of FIGS. 1 to 4 are the same as for corresponding parts of the form described with reference to FIGS. to 10, as well as the further modification of FIGS. 11 to 14 which follows.
In the form shown in FIGS. 11 to 14, blank 81 has forwardly converging front edges 82 meeting at front point 83. Side edges 84 converge rearwardly, but are close to parallel. Rear end 89 is square and of a width about one-half the maximum width of the blank but approximately three times the assembled heel width. Each corner is formed by a generally transverse but rearwardly slanted cut 88 extending inwardly from the back end of side 84 and a generally longitudinal but inward-rearward slanting cut 86 which interconnects end 89 and cut 88; cuts 86 and 88 are of about equal length.
Conductive tape 81 is adhered, glued, sewn, stapled, or otherwise attached, to blank 81 as by stitching 93, preferably commencing at a point spaced back from point 83 and extending beyond end 89 in an extended tongue 92. Transverse tape ties 96 are formed of a unitary piece of material under tape 91 and tacked by glue at locations indicated by reference numeral 97 or adhered by other means, as in the preceding modification.
Assembly of the wrapping is generally similar to the modification of FIG. 5. However, folds 104, 186, 102 are folded to the outside of the heel rather than the inside. Further, edges 96, 98 are relatively close to the centerline of the heel and only slightly displaced from the side edges of tape 92. Hence stitching 93 not only holds tape 92 in place on the blank, but also holds the folds forming the heel in assembled condition. It will be understood, however, that instead of stitching 93 other fastening means may be used, as has been previously explained. This eliminates the need for stitching similar to reference numeral 67 in FIG. 9.
In FIGS. 12 and 13, the front edges of the sides are partially overlapped adjacent point 83 and held with adhesive 111.
Use of the device is similar to the preceding modification.
FIG. 14 illustrates a still further modification of the structure of FIGS. 11 to 131 Stitching 93 is eliminated and a wire staple 112 used to hold the folds in assembled position.
In the modification of FIGS. 15-17 the formation of the heel is somewhat changed over previous modifications. Blank 121 has forwardly-converging front edges 122 meeting at a point 123 at the front. Edges 122 eX- tend about half the length of blank 121. Rearwardly thereof are slightly rearwardly-converging but substantially parallel rearwardly-extending side edges 124. Rear edges 1.26 extend obliquely, although almost transversely, inward to meet at the center. In this form of the invention, a tongue, corresponding to tongue 17 of FIG. 1, is not used. Hence the overall length of the blank is less than in previous forms described.
Tape 127 is sewn, glued or otherwise adhered to blank 121 commencing at about the middle of the blank and extending rearwardly and projecting beyond the rearward edges 126 in an extended tab 128. In the preliminary assembly step shown in solid lines in FIG. 15, tape 127 is sewn to blank 121 only about to position 129. Ties 131 consist of a single transverse length of material considerably wider than the blank which underlies tape 127 and is stitched or otherwise adhered to the blank by the same means as tape 127. Bar tacks 132 may be used, as in previous forms.
The rearward corners 133 at the juncture of edges 124, 126 are folded diagonally inward toward the center of the blank along fold lines 134 so that the corners 133 slightly overlap at the center. Lines 134 intersect edges 124 about one-quarter of the length thereof rearward of intersection with edges 122 and cross immediately forward of the center of the rear end of the blank. Which corner 133 underlies the other is immaterial. Upon completion of the first two folds the rear end of the blank is triangular having a rear apex at 136. The next step in assembly is to fold apex 136 forward along transverse fold line 137 which has a length equal to the eventual width of the heel. Stitching or other adhering of tape 127 rearward of position 129 is then completed and this operation secures folds 13 4, 137 in permanent relation. Preferably the wrapping is turned inside out, as shown in FIG. 16, so that apex 136 is inside rather than outside. The heel forms along parallel folds 138 transverse to fold 137 and said folds continue longitudinaly along the bottom in folds 139.
The materials of construction, means for joining the parts and application of the device are essentially the same as in prior forms described.
Although the foregoing invention has been described in some detail, by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be practiced within the spirit of the invention and scope of the appended claims.
