Abstract
A sock construction that substantially prevents wrinkling and bunching of the sock within the shoe. The sock construction includes a multiplicity of strategically located gripping dots disposed on the interior surface of the sock which effectively resist slippage of the sock relative to the user's foot. The gripping dots are strategically positioned so as not to restrict blood flow to the foot and so as not to inhibit normal blood circulation within the foot.
Description
- This is a Divisional Application of co-pending U.S. Ser. No. 11/187,088 filed Jul. 22, 2005.
- 1. Field of the Invention
- The present invention relates generally to socks and methods for making same. More particularly, the invention concerns an improved gripping sock having a friction-gripping surface consisting of a multiplicity of closely positioned gripping dots provided on the interior surface of the foot portion of the sock.
- 2. Discussion of the Prior Art
- A variety of different types of socks have been produced in the past from various materials, including natural and synthetic yarns. Styles of prior art socks include dress socks, socks for casual wear, athletic socks and special-purpose socks for special activities.
- As a general rule, socks are made by knitting using circular knitting machines. Such machines typically knit a tubular fabric structure using a multiplicity of closely controlled latch needles and sinkers on a length of yarn. One form of prior art circular knitting machine is commercially available from the Lonati Company, S.P.A. of Brescia, Italy. In this machine the knitting action and stitch density is controlled by a program of instructions installed in a microprocessor.
- Prior art socks are generally knitted with a rim surrounding an opening at the leg portion and an opening at the toe portion. The toe opening of a machine knit sock is typically closed in a separate operation performed on one of several different types of commercially available automatic sewing machines.
- The interaction between the sock and the wearer's foot can have a profound impact on the comfort and well-being of the user. For example, a wrinkle or a bunching of the stock within the shoe will, over time, likely cause friction and skin shear which, in turn, can cause blisters, ulcers or other debilitating conditions. This result can be particularly severe with persons having poor circulation, such as persons suffering with diabetes and certain other types of physical disabilities.
- Experience has shown that unless both the sock and the shoe fit nearly perfectly, wrinkling and bunching of the sock within the shoe is generally unavoidable. It is this problem that the present invention seeks to overcome by providing a novel sock and the method of making same that will substantially prevent unwanted wrinkling and bunching of the wearer's sock within the shoe, even during periods of prolonged walking and exercise.
- It is an object of the present invention to provide a novel sock construction that substantially prevents wrinkling and bunching of the sock within the shoe. More particularly, it is an object of the invention to provide a sock construction which includes a multiplicity of strategically located gripping dots disposed on the interior surface of the sock which effectively resist slippage of the sock relative to the user's foot.
- A further important object of the present invention is to provide a sock of the aforementioned character that effectively prevents slippage of the sock relative to the user's foot without restricting blood flow to the foot and without inhibiting normal blood circulation within the foot.
- Another object of the invention is to provide a novel method for efficiently and cost effectively producing socks of the character described in the preceding paragraphs.
- Another object of the invention is to provide a stretchable sock of the aforementioned character and the method of making the sock wherein the sock is provided with a multiplicity of gripping dots spaced such that the stretch quality of the sock is not restricted by the excessive coverage of the knit fabric by the grip-dots.
- In accordance with these and other objects, the present invention concerns a sock comprising an open top, seamless fabric receptacle that extends downwardly to a closed toe end. The receptacle includes a tapered toe section that projects from the toe end and is configured to receive the toes of the wearer, a tubular generally straight-leg section that is adjacent the leg end and is dimensioned to receive at least a portion of the leg of the wearer, and a tubular, generally straight-foot section extending between the leg section and toe section. The toe, foot and leg sections of the receptacle can be knitted of a common, high-stretch yarn and are preferably configured to cause the yarn to stretch when the sock is donned. In one embodiment of the invention, the yarn comprises multiple core spun strands, each of which includes an elastomeric core and an outer sheath of substantially non-elastic fibers. This construction provides a highly stretchable, form-fitting sock that is free of seams.

Sock 24 comprises an open top, seamless fabric enclosure that extends downwardly to a closed toe end. The enclosure includes atapered toe section 24 c that projects from the toe end and is configured to receive the toes of the wearer, a tubular generally straight-leg section 24 d that is adjacent the leg end and is dimensioned to receive at least a portion of the leg of the wearer and a tubular, generally straight-foot section 24 e extending between the leg section and toe section. The foot section includes alower portion 24 f having an inner surface that engages the bottom portions of the user's foot. The toe, foot and leg sections of the enclosure are preferably knitted of a yarn that will permit stretching when the sock is donned. -
FIG. 3 is a generally perspective view of one form of asock support mandrel 26 used in connection with the performance of the first form of the method of the invention. As indicated inFIG. 3 ,mandrel 26 which comprises a portion of the apparatus of one form of the invention, includes an elongated, generally planaraluminum support member 28 having first andsecond ends intermediate ends planar portion 29 and a strategicallyshaped aperture 30 which defines a generally “V”-shapedsock capture element 32, the purpose of which will presently be described. Mandrel end 28 a is preferably tapered, while mandrel end 28 b comprises asegment 34 of reduced width. - In the performance of one form of the method of the invention, the turned inside-out starting sock shown in
FIG. 2 is stretched over the mandrel in the manner shown inFIGS. 5 and 6 with thecapture element 32 in gripping engagement with a capture area on the leg receiving portion of the sock. With this construction, the turned inside-out starting sock is securely held in position over the mandrel with the lower orsole portion 24 f of the foot receiving part of the starting sock being flattened and urged against the generallyplanar support portion 29 of the mandrel. When the starting sock is properly positioned over the mandrel in the manner shown inFIG. 5 of the drawings to form a first assemblage, the foot engaging portion of the first orinterior surface 24 b is exposed and is maintained in a substantially planar configuration. - Turning next to
FIG. 7 of the drawings, a generally perspective, diagrammatic view illustrating the emulsion deposition step of one form of the method of the invention is there shown. This step involves the use of a specially designed,apertured stencil 38 which also forms a part of the apparatus of the invention.Apertured stencil 38 which includes a central portion having a multiplicity of spaced-apartdot forming apertures 38 a, functions to permit the uniform deposition of a selected grip-dot forming emulsion on the foot engaging portion of theinterior surface 24 b of the sock. The grip-dot forming emulsion can be selected from a number of well known prior art curable emulsions including polymer emulsions, polyvinyl chloride emulsions and the like. - In the performance of the emulsion deposition step, the
apertured stencil 38 is positioned above thefirst assemblage 40 in the manner shown inFIG. 7 . Then, using a squeegee or the like (not shown), the selected emulsion, such as a liquid vinyl material, is forced through theapertures 38 a in a manner such that a multiplicity of spaced-apart, uncured grip-dots 42 are controllably deposited on the foot engaging portion of theinterior surface 24 b of the sock to form an uncured first precursor (seeFIG. 8 ). This done, the uncured grip-dots 42 are then controllably cured into yieldably deformable cured grip-dots 42 a. - This curing step is accomplished using a curing means for curing the emulsion, such as the
radiation emitting device 44 shown inFIG. 8 of the drawings.Device 44 functions to controllably cure the uncured grip-dots so as to form a first cured precursor. The radiation means can comprise either an irradiation device, such as thedevice 44 that produces infrared heat or depending on the formulation of the emulsion used to form the uncured grip-dots, it can comprise an irradiation device that produces ultraviolet light. When certain emulsions are used, the radiation means can also comprise a conventional heating means for controllably heating the uncured grip-dots. Radiation means appropriate for use in carrying out the method of the present invention are well known to those skilled in the art and are readily commercially available. It is to be understood that in practice the uncured first precursor could be positioned on a conveyor belt and passed beneath the radiation means in a manner to cure the uncured grip-dots 42. - Following the curing step, the first cured precursor thus formed is removed from the mandrel by disengaging the sock from the generally “V”-shaped gripping element and sliding the cured precursor over the end of the
mandrel 26. As depicted inFIG. 9 of the drawings, the first precursor uniquely includes a multiplicity ofgripping dots 42 a which are strategically located on the lower foot portion of the sock which is normally in engagement with the foot of the user when the sock is turned inside out and donned by the user. As previously mentioned, after the sock is donned by the user, the strategically located grippingdots 42 a function to effectively prevent slippage of the sock, relative to the user's foot, thereby avoiding blisters and uncomfortable bunching of the sock within the user's shoe. - Turning now to
FIG. 10 , an alternate form of three-dimensionalsock support mandrel 50 is there shown for use in connection with the performance of a second, alternate form of the method of the invention. As indicated inFIG. 10 ,mandrel 50, which comprises a part of the apparatus of one form of the invention, includes a generallycylindrical portion 52 for receiving the tubular, generally straight-leg section 24 d of the starting sock and abase portion 54 connected to the generally cylindrical portion.Base portion 54 includes a sock supporting, generallyplanar portion 56 for supportinglower portion 24 f of the starting sock. - In the performance of the alternate form of the method of the invention, the turned inside-out starting sock shown in
FIG. 2 is stretched over themandrel 50 in the manner shown inFIGS. 11 and 12 . With this construction, the turned inside-out starting sock is securely held in position over the mandrel with the lower orsole portion 24 f of the foot receiving part of the starting sock being flattened and urged against the generallyplanar support portion 56 of the mandrel. When the starting sock is properly positioned over the mandrel in the manner shown inFIG. 11 of the drawings to form a first assemblage, the foot engaging portion of the first orinterior surface 24 b of the sock is exposed and is maintained in a substantially planar configuration. - Turning to
FIG. 11 of the drawings, a generally perspective diagrammatic view illustrating the emulsion deposition step of this alternate form of the method of the invention is there shown. This step involves the use of a specially designed,apertured stencil 58 which also forms a part of the apparatus of the invention.Apertured stencil 58 which includes a central portion having a multiplicity of spaced-apartdot forming apertures 58 a, functions to permit the uniform deposition of a selected grip-dot-forming emulsion on the foot engaging portion of theinterior surface 24 b of the sock. As before, the grip-dot forming emulsion can be selected from a number of well known prior art curable emulsions including polymer emulsions, polyvinyl chloride emulsions and the like. - In the performance of the emulsion deposition step of this alternate form of the invention, the
apertured stencil 58 is positioned above thefirst assemblage 60 in the manner shown inFIG. 11 . Then, using a squeegee or the like (not shown), the selected emulsion such as a polymer emulsion, is forced through theapertures 58 a in a manner such that a multiplicity of spaced-apart, uncured grip-dots 62 are controllably deposited on the foot engaging portion of theinterior surface 24 b of the sock to form an uncured first precursor (seeFIG. 12 ). This done, the uncured grip-dots 62 are then controllably cured into yieldably deformable, rubber-like cured grip-dots 62 a. This curing step is accomplished in the manner previously described using a curing means for curing the emulsion, such as theradiation emitting device 44 shown inFIG. 12 of the drawings, to cure the uncured grip-dots in a manner to form a first curedprecursor 63. - Following the curing step, the first cured precursor thus formed is removed from the
mandrel 50. As depicted inFIG. 13 of the drawings, thefirst precursor 63 uniquely includes a multiplicity ofgripping dots 62 a which are strategically located on the lower foot portion of the sock which is normally in engagement with the foot of the user when the sock is turned inside-out in the manner shown inFIG. 14 and subsequently donned by the user. After the sock is donned by the user the strategically located grippingdots 62 a function to effectively prevent slippage of the sock relative to the user's foot. - Referring now to
FIGS. 15 and 16 , still another form ofsock support mandrel 66 is there shown for use in connection with the performance of a third, alternate form of the method of the invention. As indicated in the drawings,mandrel 66 which also comprises a part of the apparatus of the invention, comprises a substantially rigid,aluminum mandrel 66 which has the general shape of a human foot but is somewhat larger than the size of a normal human foot.Mandrel 66 has a first, generallyplanar surface 66 a and a second, spaced-apart generally planar, opposingsurface 66 b.Mandrel 66 here includes anupper portion 68 for receiving the tubular, generally straight-leg section 24 d of the starting sock and a lower portion for receiving and supporting thelower portion 24 f of the starting sock. - In the performance of the alternate form of the method of the invention, the turned inside-out starting sock shown in
FIG. 2 is stretched over themandrel 66 in the manner shown inFIGS. 15 and 16 . With this construction, the turned inside-out starting sock is securely held in position over the mandrel with both sides of the lower orsole portion 24 f of the foot receiving part of the starting sock flattened and urged against the sides of the generallyplanar support portion 68 of the mandrel. When the starting sock is properly positioned over the mandrel in the manner shown inFIGS. 15 and 16 of the drawings to form afirst assemblage 69, the foot engaging portion of the first orinterior surface 24 b of the sock is exposed and is maintained in a substantially planar configuration. - Turning to
FIG. 17 of the drawings, a generally perspective diagrammatic view illustrating the emulsion deposition step of this latest form of the method of the invention is there shown. This step involves the use of a specially designed,apertured stencil 70 which also forms a part of the apparatus of the invention.Apertured stencil 70 which includes a central portion having a multiplicity of spaced-apartdot forming apertures 70 a, functions to permit the uniform deposition of a selected grip-dot-forming emulsion on the foot engaging portion of theinterior surface 24 b of the sock. As before, the grip-dot forming emulsion can be selected from a number of well known prior art curable emulsions including polymer emulsions, polyvinyl chloride emulsions and the like. - In the performance of the emulsion deposition step of this latest form of the invention, the
apertured stencil 70 is positioned above thefirst assemblage 72 in the manner shown inFIG. 17 . Then, using a squeegee or the like (not shown), the selected emulsion such as a polymer emulsion is forced through theapertures 70 a in a manner such that a multiplicity of spaced-apart, uncured grip-dots 74 are controllably deposited on one side of the foot engaging portion of theinterior surface 24 b of the sock to form an uncured first precursor (seeFIG. 18 ). This done, the uncured grip-dots 74 are then controllably cured into yieldably deformable, rubber-like cured grip-dots similar to the previously described grip-dots 62 a (FIG. 18 ). This curing step is accomplished in the manner previously described using a curing means for curing the emulsion, such as theradiation emitting device 76 shown inFIG. 18 of the drawings, to cure the uncured grip-dots and to form a first curedprecursor 79. - Following this first curing step,
assemblage 69 is turned over in the manner depicted inFIG. 19 to expose the second opposite side of the first precursor. This done, theapertured stencil 70 is positioned above the turned overassemblage 79 in the manner shown inFIG. 19 . Then, using a squeegee or the like (not shown), the selected emulsion such as a polymer emulsion, is forced through theapertures 70 a in a manner such that a multiplicity of spaced-apart, uncured grip-dots 74 are controllably deposited on the second side of the foot engaging portion of theinterior surface 24 b of the sock to form an uncured second precursor (seeFIG. 20 ). This done, the uncured grip-dots 74 are then controllably cured into yieldably deformable, rubber-like cured grip-dots similar to the previously described grip-dots 62 a (FIG. 18 ). This curing step is accomplished in the manner previously described using a curing means for curing the emulsion such as theradiation emitting device 76 shown inFIG. 20 of the drawings, to cure the uncured grip-dots and to form a second cured precursor. - Following the second curing step, the second cured precursor thus formed is removed from the
mandrel 66. The second precursor formed by depositing grip-dots on both sides of theinterior surface 24 b of the foot engaging portion of the sock 63 (seeFIG. 13 ) uniquely includes a multiplicity of gripping dots which are strategically located on the lower foot portion of the sock which is normally in engagement with the foot of the user when the sock is turned inside-out from that shown inFIG. 20 and subsequently donned by the user. After the sock is donned by the user, the strategically located gripping dots once again function to effectively prevent slippage of the sock relative to the user's foot. - Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
