The present invention relates to a method of making articles, and in particular to a method of applying graphics to an article.
Methods of customizing an article of footwear have been previously proposed. Abrams et al. (U.S. Pat. No. 7,166,249) is directed to an in-mold decorating process. Abrams teaches a method of applying a sheet with a printed graphic to a mold in order to create a molded product that includes the printed graphic. Abrams teaches a method that allows for the in-mold decoration of deep dimensional and three dimensional molded parts.
Abrams teaches an embodiment for applying an image to a molded duck decoy. First, left and right photographic images of the duck are produced using distortion printing to compress the image in designated areas. The sheet is then coated using screen printing techniques. The printed and coated sheet is then vacuum formed to the dimensions of a duck decoy causing the distortion printed areas to assume normal color and proportion. The vacuum formed printed sheet is cut into left and right view pieces which are then placed in the appropriate cavities of a blow mold and molded with polyethylene. When the mold is opened two halves of a duck decoy having a photographic quality image are removed and mated to form a finished decoy.
A method of customizing an article is disclosed. In one aspect, the invention provides a method of applying a graphic to an article, comprising the steps of: filling an inflatable member with fluid; associating the article with the inflatable member; associating the graphic with a surface of the article; pressing a deformable membrane against a portion of the article so that the deformable membrane conforms to the surface; heating the deformable membrane; and thereby transferring the graphic to the surface.
In another aspect, the invention provides a method of using a graphic transfer assembly, comprising the steps of: attaching an inflatable member to the graphic transfer assembly; inflating the inflatable member to a first size; associating a first article with the inflatable member, the first article having the first size; transferring a first graphic to a portion of the first article using the graphic transfer assembly; removing the first article from the inflatable member; inflating the inflatable member to a second size, the second size being different from the first size; associating a second article with the inflatable member, the second article having the second size; and transferring a second graphic to a portion of the second article using the graphic transfer assembly.
In another aspect, the invention provides a graphic transfer assembly, comprising: a base portion configured to support the graphic transfer assembly; a first moveable portion including a first deformable membrane and a second moveable portion including a second deformable membrane; an actuator configured to control the first moveable portion and the second moveable portion between an open position and a closed position; a support assembly configured to attach an inflatable member to the base portion; the support assembly including a first fluid port configured to fill an interior chamber of the inflatable member with fluid; the support assembly also including a second fluid port, the second fluid port configured to apply a vacuum between the first deformable membrane and the second deformable membrane; the actuator configured to control the first moveable portion and the second moveable portion; and wherein the first deformable membrane and the second deformable membrane are configured to conform to a portion of an article and thereby transfer a graphic to the article.

In another embodiment, for example, support member 3150 can be configured with a column-like geometry having a circular cross-sectional shape.
Generally, support member 3150 may be attached to inflatable member 3100 in any manner. In some embodiments, support member 3150 may be fixedly attached to inflatable member 3100. In other embodiments, support member 3150 may be removably attached to inflatable member 3100. In an exemplary embodiment, support member 3150 may be fixedly attached to inflatable member 3100 using support plates.
In some embodiments, inflatable member 3100 may include first support plate 3161 and second support plate 3162. In some cases, first support plate 3161 may be disposed on an external surface of top portion 3122 of inflatable member 3100. In addition, second support plate 3162 may be disposed on an internal surface of top portion 3122. In other words, second support plate 3162 may be disposed within interior chamber 3190 of inflatable member 3100. Furthermore, first support plate 3161 may be joined with second support plate 3162 using one or more fasteners that are further inserted through top portion 3122. In other words, top portion 3122 is sandwiched between first support plate 3161 and second support plate 3162, which allows first support plate 3161 and second support plate 3162 to be anchored in place with respect to top portion 3122.
In some embodiments, inflatable member 3100 may include third support plate 3163 and fourth support plate 3164.

In an exemplary embodiment, support member 3150 extends between support plates on top portion 3122 and bottom portion 3120. In particular, first end 3151 of support member 3150 is joined with second support plate 3162. Also, second end 3152 of support plate 3150 is joined with fourth support plate 3164. With this arrangement, support member 3150 may be held fixedly in place between top portion 3122 and bottom portion 3120.
In different embodiments, the geometries of one or more support plates can vary. In one embodiment, first support plate 3161 and second support plate 3162 can have substantially circular shapes. In some cases, the circular shapes for first support plate 3161 and second support plate 3162 correspond approximately to the shape of top portion 3122. In addition, in one embodiment, third support plate 3163 and fourth support plate 3164 can have elongated shapes with rounded end portions. In some cases, the shapes of third support plate 3163 and fourth support plate 3164 can correspond approximately to the shape of bottom portion 3120. In other embodiments, however, each support plate can have any other type of shape.
Although four support plates are used in the current embodiment, in other embodiments more or less than four support plates can be used. For example, in another embodiment, a first support plate may be disposed on a bottom portion of an inflatable member and a second support plate may be disposed on a top portion of an inflatable member. In some cases, the first support plate can be fastened directly to the bottom portion and the second support plate can be fastened directly to the top portion, rather than using a sandwiching arrangement as discussed above. Furthermore, in this alternative arrangement, the support member can be connected to the first support plate and the second support plate. Additionally, in still other embodiments, additional support plates can be provided on different portions of an inflatable member, including lateral side portions and/or medial side portions.
In some embodiments, inflatable member 3100 can include provisions for engaging with graphic transfer assembly 3000. In some embodiments, inflatable member 3100 can include stem 3130 for engaging with last post 3010. In some cases, stem 3130 can be associated with fluid port 3132, which is in fluid communication with interior chamber 3190 of inflatable member 3100. In other embodiments, however, inflatable member 3100 may not include a stem. In another embodiment, for example, a fluid port can be disposed on first support plate 3161 or directly on top portion 3122.
Generally, stem 3130 can be joined to inflatable member 3100 in any manner. In some cases, stem 3130 can be joined to inflatable member 3100 using an adhesive. In other cases, stem 3130 can be attached to inflatable member 3100 using fasteners. In other embodiments, stem 3130 may be integrally formed with a support plate. In an exemplary embodiment, step 3130 may be integrally formed with first support plate 3161 of inflatable member 3100.
In some embodiments, stem 3130 can include fluid port 3132 that is in fluid communication with interior chamber 3190 of inflatable member 3100. Generally, fluid port 3132 can be any type of port known in the art for controlling the flow of fluid between two regions. In some embodiments, fluid port 3132 may be associated with one or more air valves. For example, in one embodiment, fluid port 3132 may include a one way valve that helps to prevent fluid from leaving interior chamber 3190 but allows air to enter interior chamber 3190. In other embodiments, any other provisions known in the art for controlling the flow of fluids into or out of an inflatable device can be used.
In some embodiments, support member 3150 can include fluid port set 3155. Generally, fluid port set 3155 can comprise any number of fluid ports. In some cases, fluid port set 3155 can comprise at least five fluid ports. In other cases, fluid port set 3155 can comprise more than five fluid ports. In still other cases, fluid port set 3155 can comprise less than five fluid ports. In an exemplary embodiment, fluid port set 3155 can comprise a plurality of ports disposed on each sidewall of support member 3150.
In some cases, fluid port set 3155 may be in fluid communication with fluid port 3132. An exemplary arrangement is discussed in detail below. In other cases, however, fluid port set 3155 may not be in fluid communication with fluid port 3132.
In some embodiments, last post 3010 can include provisions for connecting with inflatable member 3100. In some embodiments, last post 3010 can include socket 3012. In some cases, socket 3012 may be a quick disconnect socket that is configured to automatically control fluid flow. Socket 3012 may also be in fluid communication with central tube 3018 of second fluid line 3062. With this arrangement, stem 3130 of inflatable member 3100 may be inserted into socket 3012 to provide fluid communication between fluid pump 3052 and inflatable member 3100.
Last stem 3010 may include provisions for supplying a vacuum between first deformable membrane 3032 and second deformable membrane 3034 (see
The arrangements illustrated and discussed in the current embodiment for first fluid line 3061 and second fluid line 3062 are only intended to be exemplary. In other embodiments, other arrangements can be provided for directing fluid between a fluid pump and an inflatable member as well as for providing a vacuum between deformable membranes. For example, while first fluid line 3061 comprises two tubes at last post 3010 in the current embodiment, in other embodiments, this portion of fluid line 3061 may be associated with more than two tubes, or only a single tube. Likewise, while second fluid line 3062 comprises a single central tube in the current embodiment, other embodiments can be associated with additional tubes.
Referring to
As illustrated in the current embodiment, some portions of stem 3130 may extend through first support plate 3161 and second support plate 3162. This arrangement may allow air to travel from fluid port 3032 into central channel 3180 of support member 3150. In other embodiments, however, stem 3130 may not extend through first support plate 3161 and/or second support plate 3162. Instead, for example, central holes or cavities of first support plate 3161 and/or second support plate 3162 can provide for fluid communication between stem 3130 and central channel 3180.
At this point, a vacuum may be applied between first deformable membrane 3032 and second deformable membrane 3034. In particular, air disposed between first deformable membrane 3032 and second deformable membrane 3034 may be evacuated using first fluid line 3061 that is connected to vacuum pump 3050. In particular, air trapped between first deformable membrane 3032 and second deformable membrane 3034 may be pulled through first vacuum port 3015 and second vacuum port 3017 down first tube 3014 and second tube 3016, respectively, of first fluid line 3061. Eventually, as a substantial entirety of the air is evacuated, first deformable membrane 3032 and second deformable membrane 3034 may be pulled tightly against the outer surface of article of footwear 3200. In particular, first deformable membrane 3032 and second deformable membrane 3034 may conform to curved portions of article of footwear 3200. Furthermore, graphic 3210 may be pressed against curved portion 3212 of article of footwear 3200 using second deformable membrane 3034.
In different embodiments, the materials used for different portions of an inflatable member can vary. In some cases, a body portion, which is configured to expand or otherwise elastically deform, can be made of a substantially elastic material or any other type of material, such as the materials disclosed above. In addition, a support member can be made of any material. In some cases, a support member can be made of a substantially rigid material including, but not limited to, metal, a rigid plastic, wood as well as any other substantially rigid material. In other cases, a support member may comprise a material that is substantially elastic and capable of deforming with an inflatable member. Furthermore, support plates used with an inflatable member can be made of materials having any rigidity. In some cases, support plates can be made of a substantially rigid material including, but not limited to, metal, plastic, wood or other rigid materials. In other cases, however, support plates can be made of any other kind of material. In an exemplary embodiment, a support member and one or more support plates used with an inflatable member can be made of a substantially rigid material, such as a material comprising metal, in order to provide a substantially rigid frame for the inflatable member. Also, by using substantially rigid materials, the durability of a support member and/or support plates can be increased so that an inflatable member can be used for extended periods of time before replacement. This can help to protect against premature wear caused by the use of the inflatable member in creating multiple sizes of footwear, which increases the time of use over traditional lasts that are used for creating a single size of footwear.
A graphic transfer assembly can include provisions for reducing the number of lasts required to apply graphics to articles of various sizes. In some cases, a graphic transfer assembly can be associated with a last with a variable size. In an exemplary embodiment, a graphic transfer assembly can be associated with an inflatable member with a variable size.
Referring to
In some embodiments, each article of a set of articles may be associated with a corresponding last of a similar size. In other embodiments, a single last may be used for articles of two or more different sizes. In an exemplary embodiment, set of articles 2900 may be associated with inflatable member 2920. In particular, inflatable member 2920 may be configured to inflate to various sizes that are configured to fit articles of a predetermined size. For example, in this embodiment, inflatable member 2920 may be configured to inflate to first size 2922 that is configured to fit third article 2903. In addition, inflatable member 2920 may be configured to inflate to second size 2924 that is configured to fit second article 2902. Also, inflatable member 2920 may be configured to inflate to third size 2926 that is configured fit first article 2901. With this arrangement, a single inflatable member can be used to provide support to articles of varying sizes for the purposes of applying a graphic to the article.
It will be understood that in different embodiments an inflatable member can be associated with varying ranges of shoe sizes. For example, in one embodiment, an inflatable member can be configured to accommodate any article with a size in the range between size 7 and size 8. In another embodiment, an inflatable member can be configured to accommodate any article with a size in the range between size 7 and size 9. In still another embodiment, an inflatable member can be configured to accommodate any article with a size in the range between size 5 and size 9. The ranges discussed here are only intended to be exemplary and in different embodiments an inflatable member can be used with articles of any standard or non-standard sizes.
In some cases, the material comprising an inflatable member can vary to accommodate different degrees of stretching. For example, in embodiments where an inflatable member may be used with a wide range of sizes, the inflatable member may be made of a substantially elastic material that is capable of expanding over several article sizes. However, in embodiments where an inflatable member may only be used with a narrow range of sizes, the inflatable member can be made of materials with a lower elasticity since the inflatable member may only undergo slight expansion.
Using a single inflatable member for articles of varying sizes can help reduce manufacturing costs over systems that require the use of a distinct last for each distinct article size. As an example, an embodiment using inflatable members that are configured to vary between a predetermined whole size and the next half size can substantially reduce the overall number of lasts required to operate a graphic transfer assembly by almost half. In particular, where a traditional last system would require distinct lasts for sizes 5, 5½, 6, 6½, 7, 7½, 8, 8½, 9, 9½, 10 and 10½, which is a total of 12 lasts, using inflatable members capable of expanding by half a size could reduce the total number of lasts used to 6, since each whole and next half size could be associated with a single inflatable member. Furthermore, in embodiments where an inflatable member is capable of expanding through a larger range of sizes, the number of lasts required to operate a graphic transfer assembly can be further reduced.
In addition to reducing manufacturing costs due to a decreased number of lasts required to operate a graphic transfer assembly, using an inflatable member can also help reduce manufacturing costs by increasing the efficiency of the graphic transfer assembly. In particular, in some cases, the size of an inflatable member can be varied in a shorter period of time than the time required to remove one last of a particular size and attach another last of a different size. This arrangement may help reduce the time required to apply graphics to articles of varying sizes.
An inflatable member used with a graphic transfer assembly can include provisions for providing varying types of rigidity. In some cases, an inflatable member can include a first portion having a first rigidity and a second portion having a second rigidity that is different from the first rigidity.
In some cases, inflatable member 2950 can be inserted into article 2980 in a partially deflated state. Since intermediate portion 2956 is less rigid than first side portion 2952 and second side portion 2954, first side portion 2952 and second side portion 2954 may be disposed closer together as intermediate portion 2956 elastically compresses. This arrangement may help inflatable member 2950 insert more easily into article 2980.
After inflatable member 2950 has been fully inserted into article 2980, inflatable member 2950 may be fully inflated. In particular, intermediate portion 2956 may be configured to elastically expand to allow first side portion 2952 and second side portion 2954 to be pressed along the interior side walls of article 2980. With this arrangement, first side portion 2952 and second side portion 2954 may provide substantially rigid support for applying any graphics to the sides of article 2980 using a graphic transfer assembly.
While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
