Description




TECHNICAL FIELD




This invention relates to footwear and methods of constructing footwear.




BACKGROUND




A variety of constructions for making footwear are used by the footwear industry. For the most part, each footwear construction has characteristics that make it particularly well suited for durability, comfort, and ease of production. Typically, in an effort to improve efficient manufacturing and the aesthetic appeal of the footwear, a number of different assembly methods can be used.




SUMMARY




In a general aspect of the invention, a method for constructing footwear includes forming an upper assembly, providing an outsole including a recessed region and a groove region formed around a periphery of the outsole, and attaching the upper assembly to the outsole. Forming the upper assembly includes providing a gasket, a fitted upper including a vamp attached to a socklining, and attaching the fitted upper to the gasket.




In embodiments of the invention, one or more of the following features may also be included. The method also includes close-seaming the gasket around a perimeter of the socklining.




In certain embodiments, the method includes providing a groove molded around an outsole peripheral region, and pushing a lower edge of an Opanka stitched gasket into the groove.




As yet another feature, the method includes covering the outsole with a wrapper, the wrapper covering an outsole heel region and an outsole front region.




Further, the method comprises adhesively attaching a cushioning layer within the recessed region of the outsole.




As another feature, the method includes sewing the upper assembly to the outsole by using an Opanka stitch series as well as stitching the gasket using the Opanka stitch series to an outsole perimeter rim, thus forming a double seam Opanka stitch series. The sewing can be hand-made.




Moreover, the method includes pushing an upper edge of the wrapper into the groove, joining a lower edge of the Opanka stitched impression gasket.




According to another aspect of the invention, a footwear includes an upper assembly and an outsole including a recessed region and a groove region formed around a periphery of the outsole. The outsole is attached to the upper assembly. The upper assembly includes a gasket and a fitted upper including a vamp attached to a socklining, and the fitted upper attached to the gasket.




In embodiments of the invention, one or more of the following features may also be included. The gasket is close-seamed around a perimeter of the socklining, and a groove molded is provided around an outsole peripheral region. A lower edge of an Opanka stitched gasket is inserted into the groove.




In certain embodiments, the outsole is covered with a wrapper. The wrapper can cover an outsole heel region and an outsole front region.




As another feature, a cushioning layer is adhesively attached within the recessed region of the outsole.




As yet another feature, a heel is provided in the outsole. Moreover, the upper assembly of the footwear is sewed to the outsole by using Opanka stitch series and the impression gasket is stitched to an outsole perimeter using the Opanka stitch series.




In addition, an upper edge of the wrapper is inserted into the groove joining a lower edge of the Opanka stitched impression gasket.




As another feature, the upper assembly of the footwear is made of leather and the outsole is made of polyurethane. The gasket can be made of the same material as the upper assembly. As another feature, a walking surface layer having a notch line across in an outsole peripheral region is provided with the notch line accommodating the wrapper around an outsole heel region and an outsole front region.




Embodiments may have one or more of the following advantages.




Among other advantages of making footwear using the above described method is that an outsole is configured to readily receive a completed upper assembly. Thus, the upper assembly can be simply and economically attached to the outsole. Another advantage of this method lies in providing a styled, durable, and lightweight footwear. Given a practical outsole to which an upper assembly can be readily attached and stitched to form an Opanka stitch series, the process efficiently streamlines footwear production and manufacturing.




Another advantage is that the process of attaching the upper assembly to the outsole provides durability and resistance to all the components of the footwear. Even with prolonged daily wear on abrasive walking surfaces, the outsole is less prone to deformation due to the flexibility, resilience, solid design, and strength of the outsole.




In addition, this method of making footwear inherently enhances the overall appearance of the footwear by permitting genuine hand-sewn seams in the form of double-seam Opanka stitch series provided around the entire periphery of the shoe. A fashionable style results not only from the various durable components but also from the superior look of their combined assembly. Another advantage of this footwear is the enhanced comfort provided by the cushioning layer of the outsole and the flexible design of the outsole, which significantly reduces foot and leg muscle fatigue.




Moreover, the pre-engineered apertures in the impression gasket provided for forming the hand-sewn seams ensure accuracy of seaming and wrapping locations as required for improved fitting qualities.




Furthermore, the footwear has a smoother, finished interior without requiring a platform. Accordingly, a wearer's foot rests on the socklining which rests on the cushioning layer, thereby creating optimum comfort conditions.




The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION




Referring now to the figures in which identical elements are numbered identically throughout, a description of the embodiments of the present invention will now be provided.




A dress-type sandal footwear


10


is described with respect to

FIGS. 1-7

. Footwear


10


is constructed by joining an upper assembly


50


to an outsole


12


. The upper assembly


50


includes a fitted upper


15


formed by a vamp


2


attached to a socklining


4


, preferably by machine-sewing, forming an internal spacing


8


where a wearer's foot is inserted. The upper assembly


50


further includes an impression gasket


6


that is combined with the fitted upper


15


and the socklining


4


.




Referring to

FIG. 1

, the vamp


2


covers the upper region of a wearer's foot and toes. The vamp


2


can have various types of designs and constructions (e.g., close-toe design or open-toe design). The vamp


2


can also include ornamental features. In this embodiment, the vamp


2


includes a vamp strap


5


that is held by a strap holder


7


. The vamp strap


5


includes a perimeter border stitching


11


to prevent loose threads and give the footwear


10


a styled clean appearance. Aesthetic decoration is provided so that the footwear


10


can have a distinctive appeal. In addition, vamp slits


3


are formed which not only provide a stylish and attractive quality but also help ventilate the wearer's foot especially when the wearer is barefoot. The vamp


2


, in this embodiment, incorporates a toe box design so that the internal spacing


8


especially in the toe region (not shown) provides roomier spacing for accommodating the wearer's toes. This way, the wearer can prevent various toe ailments and also easily place or remove the footwear


10


from her feet. Moreover, the vamp


2


may also include an inner liner


9


to cover an interior wall of the vamp


2


for aesthetic as well as practical purposes such as absorbing moisture when the footwear


10


is again worn barefoot. Thus, in general, the shape and design of the vamp


2


increases comfort by providing a roomier and more relaxed fit.




Referring to

FIG. 2

in particular, the upper surface


44


of the socklining


4


is shown stitched to the impression gasket


6


. The vamp


2


is shown attached to the socklining


4


by a close-seam


48


, i.e., forming a line of junction by sewing together two pieces of material along their margins and hiding the stitching by reversing, along the socklining perimeter


17


extending the region corresponding to the internal spacing


8


of the footwear


10


. In this embodiment, the socklining


4


includes a padding to provide cushioning and support to the wearer's foot. The socklining


4


is made up of two components: a socklining skeleton


34


and a socklining base


36


. The socklining base


36


includes a larger surface area than the socklining skeleton


34


. The socklining skeleton


34


is superimposed on the socklining base


36


and then machine sewed, thereby forming a socklining seam


38


. The socklining skeleton


34


includes an arch support


40


. The arch support


40


as well as the socklining skeleton


34


have air apertures


25


to increase the porosity of the already porous socklining


4


for foot ventilation, drying, and comfort. The socklining


4


includes an ornamental label


42


for brand recognition. The socklining


4


is made of any suitable material. In some embodiments, the socklining


4


is decoratively quilted to provide an aesthetically pleasing look to the interior surface of the footwear


10


.




Still referring to

FIG. 2

, once the socklining


4


is joined to the vamp


2


, a fitted upper


15


is formed. The fitted upper


15


is attached to the impression gasket


6


along the socklining perimeter


17


by a close-seam operation. In this embodiment, the impression gasket


6


is formed by two “U-shaped” parts, a first part


6




c


covers a front portion of the impression gasket


6


and a second part


6




d


covers a rear portion of the impression gasket


6


. Both parts


6




c


and


6




d


include perforation for the Opanka stitching, as described further below. The impression gasket


6


includes a series of interior perforation


54


and a corresponding series of perimeter perforation


56


preformed in the impression gasket


6


in preparation for the Opanka stitch


14


. Further, the impression gasket


6


includes overlap ends


28


formed by an assembly-line production of this component at the manufacturing level.




Referring to

FIG. 3

, an under surface


46


of the socklining


4


having the impression gasket


6


attached to the socklining


4


is illustrated. Various components of the upper assembly


50


are joined by the closed seam


48


and a vamp seam


49


. In particular, the socklining base


36


and the socklining skeleton


34


(

FIG. 2

) are close seamed with the fitted upper


15


, and the first part


6




c


and second part


6




d


of the impression gasket


6


are close seamed thus forming the close seam


48


. The impression gasket


6


is also joined to the socklining base


36


in the close seam


48


. Although this embodiment only uses one close seam


48


, other embodiments may include more than one stitch series, preferably provided by a machine stitching operation, for attaching the various components of the fitted upper


15


. In addition, the vamp seam


49


joins the vamp


2


to the socklining


4


, and the socklining seam


38


joins the socklining base


36


to the socklining skeleton


34


.

FIG. 3

also shows the ornamental label


42


stitched with a seam


43


to the socklining base


34


.




The outsole


12


of the footwear


10


will now be described. Returning to

FIG. 1

, the outsole


12


is illustrated including a heel


16


, a wrapper


18


, a walking surface layer


20


, and non-skid bumps


22


. The outsole


12


is described in more detail with respect to

FIG. 4

below.




Referring to

FIG. 4

, the outsole


12


includes an upper surface


74


, having a recessed region


78


bordered by an outsole perimeter rim


70


. The recessed region


78


includes outsole cavities


72


for reducing the weight of the outsole


12


and providing added elasticity to the completed footwear


10


. The outsole perimeter rim


70


includes outsole stitching holes


60


along the entire area of the outsole perimeter rim


70


.




The recessed region


78


accommodates a cushioning layer


58


, preferably made of foam material such as polyurethane. The cushioning layer


58


is positioned over the entire area of the recessed region


78


. The softness and shock-absorbent qualities of the polyurethane can be varied from application to application by using a variety of well-known techniques, such as adjusting the type and proportionate amount of reactants. In addition, the softness and shock-absorbent qualities of the foam can be varied by adjusting the volume of foam deposited in the recessed region


78


.




The cushioning layer


58


includes reduced edges and is preferably about 3-5 mm in thickness. The cushioning layer


58


provides shock-absorption and gives the support needed to provide soft cushioning and long term comfort. The cushioning layer


58


is bound tightly to the recessed region


78


and the under surface


46


of the socklining


4


using an adhesive and is further held securely in place by the Opanka stitch series


14


. Preferably, the cushioning layer


58


is shaped in conformity with the recessed region


78


and spaced about ¼ inch from the outsole perimeter rim


70


of the outsole


12


.




The outsole


12


provides a flexible and durable structure for the footwear


10


. Accordingly, for its construction, the outsole


12


is preferably made of polyurethane although it may be produced using any suitable material having similar characteristics. Lightweight plastic materials may be used. The outsole


12


is also preferably designed to provide a styled silhouette making the footwear


10


aesthetically desirable as well as extremely comfortable.




The outsole


12


includes the heel


16


covered by a wrapper


18


. The characteristics of the heel


16


are best described with respect to

FIG. 5

where the outsole


12


includes, in large part, an outsole heel region


82


.




Referring now to

FIG. 5

, a side view of the outsole


12


is shown with only an outsole front region


87


covered with the wrapper


18


(area


66


) and with the remaining outsole heel region


82


(area


68


) not covered by the wrapper


18


, for illustration purposes only. Outsole perimeter rim


70


of

FIG. 4

becomes the outsole upper side strip


84


. A groove


80


is formed between the outsole upper side strip


84


and the outsole heel region


82


. The groove


80


is molded around an outsole upper peripheral region


62


and extends along the entire peripheral region


62


.




The outsole heel region


82


includes outsole side heel areas


83




a


and


83




b,


shaping the heel


16


like a wedge, thicker at the heel end and tapered to a thin edge at the front end of the footwear


10


, i.e., the front region


87


.




In the area


68


where the outsole


12


is not covered by the wrapper


18


, the groove


80


is shown as illustrated in

FIG. 4

, which is used in the operation that forms the double seam Opanka stitch


14


.




In contrast, when the outsole


12


is covered by the wrapper


18


, a forward region


30


and a rearward region


32


of the wrapper


18


covers the outsole front region


87


and the side heel areas


83




a


and


83




b,


respectively. When the wrapper


18


covers the outsole


12


, the notch line


24


serves to guide the placement of the wrapper


18


around the outsole


12


, beginning and finishing this wrapping process at the overlap ends


26


. The notch line


24


is positioned in a lower peripheral region


64


immediately above the walking surface layer


20


. The walking surface layer


20


has a downward tapered configuration ending at an under surface


76


. The under surface


76


includes non-skid bumps


22


that provide traction against slippery walking floors or surfaces.




Referring back to

FIGS. 1 and 4

, the wrapper


18


and the impression gasket


6


join at the groove


80


provided the wrapper


18


covers the outsole


12


. In particular, a lower edge


6




b


of the Opanka-stitched impression gasket


6


is tucked within or inserted into the groove


80


. As the wrapper


18


covers the outsole


12


, the lower edge


6




b


is joined by an upper edge


85


of the wrapper


18


which runs along the upper peripheral region


62


of the outsole


12


. In other words, the upper edge


85


of the wrapper


18


is inserted into the groove


80


thereby meeting with the lower edge


6




b


of the impression gasket


6


. This ‘tucking’ operation which produces a high quality dress-type shoe like the footwear


10


will be further described below in connection with a description of its construction process.




Furthermore, in this embodiment, the wrap


18


that covers the outsole


12


and the upper assembly


50


are made of the same material (e.g., leather). This way, footwear


10


has a coherent, pleasing look. The footwear


10


can be made from several different types of leather. An inner lining


9


(shown in

FIG. 2

) may also be made of a thinner, more absorbent, and breathable type of leather, or polyester. Although leather is preferably the material of choice for quality dress type sandals like the footwear


10


, a suitable material with good qualities, i.e., light-weight, tear resistant, durable, and stylish, can be used. For example, high quality stitched-in textile made of strong fiber material, can be used for the construction of the upper assembly


50


and the wrap


18


.




The double seam operation will now be described with respect to

FIG. 6

which shows an upper surface


86


of the footwear


10


. The upper Opanka stitch series


14




a


attach the impression gasket


6


to the outsole


12


, namely, the outsole perimeter rim


70


, through the interior perforation


54


of the gasket


6


. The upper Opanka stitch series


14




a


is best illustrated in the schematic side view of the footwear


10


provided in FIG.


1


. In a complementary manner, the upper Opanka stitch series


14




a


is accompanied by a side Opanka stitch series


14




b,


thus creating the ‘double seam’ sophisticated styled look characteristic of this embodiment.




Referring to

FIG. 7

, an under surface


76


of the footwear


10


is illustrated. The under surface


76


shows the tapered, curved configuration of the heel


16


. The outsole side heel areas


83




a


and


83




b


are clearly shown in relation to a heel back edge


89


. The under surface


76


includes, most importantly, the walking surface layer


20


having non-skid bumps


22


in a pattern of small circular dots. Such a pattern has both practical and aesthetic considerations. The walking surface layer


20


is preferably made of molded polyurethane and ensures that the contact between the ground and the walking surface is uniformly distributed so that the footwear


10


can be worn for prolonged periods. Moreover, the non-skid bumps


22


provide heel support, lift, and protection from slippery surfaces providing improved traction and safety. In addition, the heel back edge


89


and the outsole side heel areas


83




a


and


83




b


are designed to create the appearance of a highly styled heel


16


.




The construction method for this embodiment will now be described in conjunction with the accompanying figures.




In preparation for constructing the footwear


10


, the vamp


2


is cut, stitched, and finished. Ornamental details are provided in the vamp


2


if desired.




The components of the socklining


4


are also assembled, cut, and stitched. In particular, the socklining skeleton


34


is stitched to the socklining base


36


forming the socklining seam


38


. If desired, the ornamental label


42


is now affixed to the socklining base


36


in the upper surface


44


. Then, the vamp seam


49


joins the vamp


2


to the socklining


4


. The attachment of the socklining


4


to the vamp


2


can be performed as in a California construction thereby providing the fitted upper


15


.




Next, the impression gasket


6


is stitched to the socklining


4


to form the close seam


48


along the entire socklining perimeter


17


, preferably by a sewing operation. During this process, care is taken to ensure that the overlap ends


28


of the impression gasket effectively cover the entire socklining perimeter


17


. This way, the impression gasket


6


is close-seamed following the curves around the socklining perimeter


4


, which will accurately conform to the shape of the outsole upper peripheral region


62


, and specifically, the outsole perimeter rim


70


. This completes the manufacture of the upper assembly


50


.




At this point of the process, the outsole


12


is ready to be attached to the upper assembly


50


. The outsole


12


is molded using an appropriate polyurethane mold to form the recessed region


78


; the outsole perimeter rim


70


which includes the outsole holes


60


for the Opanka stitch series; the groove


80


; the notch line


24


; the walking surface layer


20


; and the non-skid bumps


22


. Prior to attaching the outsole


12


to the upper assembly


50


, the cushioning layer


58


is adhesively attached to the under surface


46


of the socklining


4


as well as to the recessed region


78


of the outsole


12


.




Thereafter, the interior perforation


54


and the perimeter perforation


56


of the impression gasket


6


in conjunction with the outsole holes


60


form the double seam Opanka stitch series


14


. Consequently, the Opanka stitch series


14


join the upper assembly


50


to the outsole


12


. The resulting double seam operation is described in greater detail below.




The impression gasket


6


is aligned above the outsole perimeter rim


70


so that the interior perforation


54


are aligned above the series of outsole holes


60


. In particular, the double seam


14


is formed by creating an upper Opanka stitch series


14




a


by passing a suitable and durable thread through the interior perforation


54


and the outsole holes


60


and also creating a side Opanka stitch series


14




b


by passing preferably the same thread through the perimeter perforation


56


. This double seam


14


operation generates a rounded edge


6




a


and the lower edge


6




b


of the impression gasket


6


as shown in FIG.


1


. Moreover, the rounded edge


6




a


forms the upper side strip


84


as illustrated in FIG.


5


.




Subsequently, the lower edge


6




b


is tucked inside the groove


80


forming a neatly packed upper assembly


50


joined to the outsole


12


.




In this embodiment, the wrapper


18


is provided to cover the outsole


12


, in particular, the outsole heel region


82


, i.e., the outsole side heel areas


83




a


and


83




b,


the outsole front region


87


, and the heel back edge


89


. The forward region


30


of the wrapper


18


is cut to accurately fit the thinner width shape of the outsole front region


87


and similarly the rearward region


32


of the wrapper


18


is cut to fit the shape of the outsole heel region


82


. As the wrapper


18


is prepared to cover the outsole


12


, the notch line


24


guides the close-fit placement of the wrapper


18


, specifically, in the outsole lower peripheral region


64


. The wrapper


18


is aligned with and wrapped around the outsole


12


, from one of the overlapping ends


26


to another, both of which are then glued together when they meet so that no loose pieces of the overlap ends


26


will be formed. The notch line


24


allows the wrapper


18


to present a smooth and stylish look for the entire footwear


10


by providing a structural separation layer between the walking surface layer


20


and the outsole


12


which is covered by the wrapper


18


.




Finally, in this embodiment, as the wrapper


18


covers the outsole


12


, the upper edge


85


of the wrapper


18


which runs around the upper peripheral region


62


of the outsole


12


is tucked in or inserted into the groove


80


. That is, the upper edge


85


of the wrapper


18


joins the lower edge


6




b


of the impression gasket


6


inside the groove


80


. Accordingly, the groove


80


securely holds the upper edge


85


of the wrapper and the lower edge


6




b


of the impression gasket


6


folded in. The result is a ‘tight’, well-formed design without any unsecured or loose parts. Although the wrapper


18


is provided in this particular embodiment, outsole


12


can be used without any covers such as the wrapper


18


. The completed footwear is shown in FIG.


1


.




In another embodiment as shown in

FIG. 8

, a footwear


10




a


is provided having a flat outsole


12




a


attached to an upper assembly


50




a


by an Opanka stitch series


14


. An impression gasket


6




e


is provided extending the length of the footwear


10




a.


The impression gasket


6




e


includes two “U-shaped” parts. A first part


6




f


covers a front portion of the impression gasket


6


and a second part


6




g


covers a rear portion of the impression gasket


6


. Both parts


6




f


and


6




g


include perforation for the Opanka stitching. In another embodiment as shown in

FIG. 9

, a heel


16




b


is in the form of an open heel type with an outsole


12




b


shaped accordingly.




Although the invention, preferably relates to casual sandals, other fields of application are entirely within the scope of the invention, especially in the broad sector of footwear manufacturing.
