SPACERMESH STRUCTURE FOR SHOEMAKING
Abstract
A spacermesh structure is provided for shoemaking, wherein an
intermediate intensive texture enclosed by an upper and a lower
mesh-texture layer of a conventional typical sandwich structure is
substituted by an intermediate layer having a plurality of
supporting lumps woven thereon and aligned in one direction or in
both the vertical and the horizontal directions staggeringly, and a
plurality of reinforcement supporting girders is laid in some empty
lanes in the intermediate layer for structure reinforcement, which,
the girders, may be ropes, flexible bands, foam plastic strips,
plastic strips, spring coils, metallic bars, etc.

Claims
What is claimed is:
1. A spacermesh structure for shoemaking, comprising: an upper
mesh-texture layer; a lower mesh-texture layer; and an intermediate
layer having a plurality of supporting lumps woven thereon and
aligned in one direction or in both the vertical and the horizontal
directions staggeringly, wherein a plurality of reinforcement
supporting girders is laid in reserved empty lanes in the
intermediate layer for structure reinforcement, which, the
supporting girder, is rope, flexible band, foam plastic strip,
plastic strip, spring coil, or metallic bar.
Description
FIELD OF THE INVENTION
[0001] This invention relates to a spacermesh structure for
shoemaking, wherein an intermediate intensive texture enclosed by
an upper and a lower mesh-texture layer of a typical conventional
sandwich structure is substituted by an intermediate layer having a
plurality of supporting lumps woven thereon and aligned in a single
direction or in both the vertical and the horizontal directions
staggeringly and a plurality of reinforcement supporting girders is
laid in some empty lanes in the intermediate layer for structure
reinforcement, which, the girders, may be ropes, flexible bands,
foam plastic strips, plastic strips, spring coils, metallic bars,
etc.
BACKGROUND OF THE INVENTION
[0002] The conventional spacermesh structure for shoemaking is
usually composed of an upper and a lower mesh-texture layer as well
as an air-permeable and flexible intermediate intensive texture.
Nevertheless, with more or less insufficient strength, poor
plasticity and durability, and larger deformation, such a structure
is thus compressed in its applicable field to some extent in
despite of supplementary efforts.
[0003] In view of abovesaid imperfection, after years of constant
efforts in research, the inventor of this invention has
consequently developed an improved mechanism pertaining to the
subject matter to be described below.
SUMMARY OF THE INVENTION
[0004] The primary object of this invention is to provide a
spacermesh structure for shoemaking, wherein an intermediate
intensive texture of a conventional typical sandwich structure is
substituted by an intermediate layer having a plurality of
supporting lumps woven thereon and aligned in one direction or in
both the vertical and the horizontal directions staggeringly and a
plurality of reinforcement supporting girders is laid in some empty
lanes in the intermediate layer for structure reinforcement, which,
the girders, may be ropes, flexible bands, foam plastic strips,
plastic strips, spring coils, metallic bars, etc.
[0005] For more detailed information regarding advantages or
features of this invention, at least an example of preferred
embodiment will be elucidated below with reference to the annexed
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The related drawings in connection with the detailed
description of this invention, which is to be made later, are
described briefly as follows, in which:
[0007] FIG. 1 shows a conventional spacermesh structure for
shoemaking;
[0008] FIG. 2 is an exploded view of the conventional spacermesh
structure;
[0009] FIG. 3 shows an embodiment of the conventional spacermesh
structure;
[0010] FIG. 4 is a cutaway sectional view of a reinforced
spacermesh structure of this invention; and
[0011] FIG. 5 is a schematic view of an embodiment of this
invention.
DETAILED DESCRIPTION OF THE INVENTION
[0012] As illustrated in FIGS. 1 and 2, a conventional spacermesh
structure (1) for shoemaking usually comprises an upper
mesh-texture layer (11), an intermediate intensive texture layer
(12), and a lower mesh-texture layer (13) to form a kind of soft
shoe stuff with excellent air-permeability. However, a sandwich
structure like this is particularly insufficient in structural
strength and weak in wrapping fitness that it would deform too much
to keep itself in place accordingly.
[0013] For improvement, as indicated in FIG. 3, a relatively
stronger plastic strip (15) or something the like is applied on the
vamp for reinforcement, which, as a matter of fact, doesn't avail
very much.
[0014] Now, referring to FIG. 4--a reinforced spacermesh structure
of this invention, the framework (2) contains an upper mesh-texture
layer (21), a lower mesh-texture layer (23), and an intermediate
layer (22) having a reinforcement zone (24) with empty lanes to
establish a spacermesh structure with excellent air-permeability
and flexibility. A plurality of supporting lumps is aligned in a
single direction or two perpendicular directions staggeringly in
the intermediate layer (22), wherein a plurality of reinforcement
supporting girders (25) is laid in the empty lanes of the
reinforcement zone (24); and the supporting girders (25) may be
ropes, flexible bands, foam plastic strips, etc.
[0015] In an embodiment of this invention shown in FIG. 5, the
reinforced spacermesh structure (2) is applied for shoemaking in
form of a front segment (26), a middle segment (27), and a rear
segment (28) of vamp for consolidating the shoe structure and
holding the vamp in due place.
[0016] In the above described, at least one preferred embodiment
has been described in detail with reference to the drawings
annexed, and it is apparent that numerous variations or
modifications may be made without departing from the true spirit
and scope thereof, as set forth in the claims below.
