Description

CROSS REFERENCE

The present application is a division of U.S. application Ser. No. 13/053,494 filed on Mar. 22, 2011.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to a multi-layer decorating element and, more particularly, to a multi-layer decorating element for decorating materials such like shoes or bags.
2. Description of the Related Art
Shoes have been specialized and improved for years. Currently, shoe manufacturers and designers provide specialized shoes for many activities, such as, for example, running shoes, tennis shoes, cycling shoes, walking shoes, cross-trainers, and the like. These shoes can be designed to respond to particular pressures and hot spots for the assumed usage.
U.S. Pat. No. 7,832,123 shows a set of shoes for use by members of a team. The shoes allow for a uniform appearance in a team environment by way of substantially similar uppers, while providing individualized performance specifications, with respect to support and breathability, for each upper. The substantially similar appearance of the upper may be due to material overlays, stitch patterns, color scheme and/or perforations and may be based on team criteria. The uppers are materially different from each other due to internal or external supports, material types and/or breathability.
Presently, the construction of a shoe upper requires a substantial amount of manual labor. While the production of a sole of a modern sport shoe can be automated to a great extent, the stitching of the different materials of the upper still requires a significant amount of manual labor.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, the main purpose is to provide a method for producing a multi-layer decorating element which includes the steps of (a) providing a base, a first plate, a second plate and an adhesive layer; (b) stacking the first and second plates onto one of the base and the adhesive layer; (c) stacking the other of the base and the adhesive layer onto one of the base and the adhesive layer to form a stacked array; (d) hot pressing the stacked array; and (e) removing the adhesive layer.
An advantage of the method for producing the multi-layer decorating element according to the present invention is that the first and second plates are connected with each other by hot pressing rather than stitching, thereby allowing the multilayer decorating element to be processed accurately, conveniently and in a cost-saving manner.
Other advantages and features of the present invention will become apparent from the following description referring to the drawings.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be described through detailed illustration of three embodiments referring to the drawings.
Referring to FIGS. 1 and 2, there is shown a multi-layer decorating element according to a first embodiment of the present invention. The multi-layer decorating element is adapted for coupling with an upper of the shoe (as shown in FIG. 1) or with an outer surface of a bag. The multi-layer decorating element comprises a base 10, a first plate 21 and a second plate 22 both connected to the base 10.
Referring to FIG. 3, a method for producing the multi-layer decorating element includes the steps of: (a) providing a base, a first plate, a second plate and an adhesive layer; (b) stacking the first and second plates onto one of the base and the adhesive layer; (c) stacking the other of the base and the adhesive layer onto one of the base and the adhesive layer to form a stacked array; (d) hot pressing the stacked array; and (e) removing the adhesive layer.
Referring to FIGS. 4 and 5, each of the base 10, the first plate 21 and the second plate 22 is cut to a required shape, respectively. The base 10 may be constructed of cloth or leather.
The first plate 21 may be constructed of thermoplastic polyurethane (TPU) or polyurethane (PU). The first plate 21 includes a proximal side, a distal side opposite from the proximal side and a hot melt glue layer 211 provided on the proximal side thereof in which the hot melt glue layer 211 has a release liner 9 in releasable contact therewith. The second plate 22 may be constructed of thermoplastic polyurethane (TPU) or polyurethane (PU). The second plate 22 includes a proximal side, a distal side opposite from the proximal side and a hot melt glue layer 221 provided on the proximal side thereof in which the hot melt glue layer 221 has a release liner 9 in releasable contact therewith. The adhesive layer 30 is easy to stick on and to remove from the base 10, and the first and second plates 21 and 22, even through the adhesive layer 30 is hot pressed.
Referring to FIGS. 6 and 7, the first plate 21 is stacked onto a surface of the base 10 with the release liner 9 detached, and the second plate 22 is stacked onto the first plate 21 with the release liner 9 detached. In a preferred form, each of the base 10, the first and the second plates 21 and 22 are disposed to a fixture (not shown), sequentially. The hot melt glue layer 211 of the first plate 21 is connected to the surface of the base 10 and the hot melt glue layer 221 of the second plate 22 is connected to the distal side of the first plate 21. Preferably, a periphery of the second plate 22 extends outside a periphery of the first plate 21. Hence, the second plate 22 has a first section directly disposed to the first plate 21 and a second section directly disposed to the base 10.
The adhesive layer 30 is stacked onto the base 10 to form a stacked array. Preferably, the first and second plates 21 and 22 are sandwiched between the base 10 and the adhesive layer 30 and are fixed by the adhesive layer 30 such that the first and second plates 21 and 22 are prevented from moving with respect to the base 10.
Referring to FIGS. 8 and 9, simultaneously, the stacked array is detached from the fixture and is disposed in a hot press apparatus 40, in which the hot press apparatus 40 is of a preferred temperature, time and pressure. The stacked array is heated and is pressed by the hot press apparatus 40 such that the base 10 and the first and second plates 21 and 22 would be tightly connected with each other.
Referring to FIG. 10, while the adhesive layer 30 is removed from the base 10, the process of fabricating the multi-layer decorating element is finished.
The first and second plates 21 and 22 are connected with each other by hot pressing rather than stitching, thereby allowing the multilayer decorating element to be processed accurately, conveniently and in a cost-saving manner.
FIGS. 11 through 14 show a multi-layer decorating element in accordance with a second embodiment of the present invention. Parts of the multi-layer decorating element of the second embodiment corresponding to parts of the multi-layer decorating element of the first embodiment have the same reference numerals with the suffix “b”. The second embodiment is like the first embodiment except that contours of the first and second plates 21 b and 22 b of the second embodiment are different from that of the first embodiment. Preferably, the second plate 22 b has a thickness larger than that of the first plate 21 b so that a surface of the multi-layer decorating element is ridges and hills irregularly. Additionally, a periphery of the second plate 22 b is completely within a periphery of the first plate 21 b, hence, the second plate 22 b has a first section directly disposed to the first plate 21 b and a second section directly disposed to the base 10 b.
In a preferred form, each of the adhesive layer 30 b, the first and second plates 21 b and 22 b is disposed to a fixture (not shown), sequentially. The hot melt glue layer 211 b of the first plate 21 b is connected to the surface of the base 10 b and the hot melt glue layer 221 b of the second plate 22 b is connected to the distal side of the first plate 21 b.
The adhesive layer 30 b is stacked onto the base 10 b to form a stacked array. Preferably, the first and second plates 21 b and 22 b are sandwiched between the base 10 b and the adhesive layer 30 b and are fixed by the adhesive layer 30 b such that the first and second plates 21 b and 22 b are prevented from moving with respect to the base 10 b.
Then, the stacked array is detached from the fixture and is disposed in a hot press apparatus. The stacked array is heated and is pressed by the hot press apparatus such that the base 10 b and the first and second plates 21 b and 22 b would be tightly connected with each other.
FIGS. 15 through 17 show a multi-layer decorating element in accordance with a third embodiment of the present invention. Parts of the multi-layer decorating element of the third embodiment correspond to parts of the multi-layer decorating element of the first embodiment have the same reference numerals with the suffix “c”. The third embodiment is like the first embodiment except that a stacking sequence of the stacked array of the third embodiment is different from that of the first embodiment.
While stacking the first and second plates 21 c and 22 c onto the adhesive layer 30 c, the first plate 21 c is stacked onto a surface of the adhesive layer 30 c, then, the release liner 9 c thereof is detached. The second plate 22 c is stacked onto the first plate 21 c, then, the release liner 9 c thereof is detached. In a preferred form, each of the first and second plates 21 c and 22 c is disposed to a fixture (not shown), sequentially. The distal side of the first plate 21 c is connected to the surface of the adhesive layer 30 c and the distal side of the second plate 22 c is connected to the hot melt glue layer 211 c of the first plate 21 c. Preferably, a periphery of the second plate 22 c extends outside a periphery of the first plate 21 c.
The base 10 c is stacked onto the adhesive layer 30 c to form a stacked array. Preferably, the first and second plates 21 c and 22 c are sandwiched between the base 10 c and the adhesive layer 30 c and are fixed by the adhesive layer 30 c such that the first 21 c and second 22 c plates are prevented from moving with respect to the base 10 c. Additionally, the second plate 22 c has a first section directly connected to the first plate 21 c and a second section directly connected to the base 10 c.
The stacked array is detached from the fixture and is disposed in a hot press apparatus (not shown). Referring to FIGS. 18 and 19, while the adhesive layer 30 c is removed from the base 10 c, the process of fabricating the multi-layer decorating element is finished.
The present invention has been described through the illustration of the embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Hence, the embodiments shall not limit the scope of the present invention defined in the claims.
