Description

Expandable-and-contractable shoe

(1) technical field:

The utility model relates to expandable-and-contractable shoe.Belong to human life need part, individual or household goods branch, the big class of footwear, the feature of footwear by International Patent Classification (IPC) (IPC) division; The parts group of footwear is with as feature big group of shape or purposes, the little technical group field of footwear of adjustable length or size.Classification number is A43B3/26.

(2) background technology:

At present, existing and once had about with shape or purposes big group as feature, the technology of the footwear of adjustable length or size was all done very fruitful effort to the demand of expandable-and-contractable shoe, also once designed many outstanding technical schemes.As being declared by Tao He of the Decree of Patent Office of China in 1996, Granted publication number is CN2235215Y, and China Patent No. (ZL) is: No. 95233560.3 utility model title is the utility model patent of " ordering footwear certainly ", the technical scheme that is adopted.With as feature big group of shape or purposes, the footwear technical elements of adjustable length or size is a routine of great value invention, and it has solved the problem of ordering footwear certainly effectively.But still have some deficits, the footwear yardage before it also is difficult to solve is fixed the problem that can not arbitrarily stretch.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of expandable-and-contractable shoe.Fix the problem that arbitrarily to stretch to solve former footwear yardage.

The purpose of this utility model is achieved in that the expandable-and-contractable shoe of this utility model.Mainly by preceding vamp, upper of a shoe, telescopic band, rear vamp, preceding sole, press nail, back sole, snap-fastener constitute.It press nail, snap-fastener by selecting for use on the market.Its preceding vamp is common vamp shape, uses cloth material, through making processing and manufacturing.Its upper of a shoe, telescopic band are elongate in shape, use the ox-hide material, through cutting out processing and manufacturing.Its rear vamp is barrel-shaped shape, uses cloth material, through making processing and manufacturing.Its preceding sole, back sole are the elliptical piece shapes, use elastomeric material, through moulding processing and manufacturing.The back-end location of vamp constituted the conjuncted structure of Y word shape before upper of a shoe adopted method of sewing to be connected, and function has been firm effect.The back-end location of vamp constituted the conjuncted structure of elongate in shape before telescopic band adopted method of sewing to be connected, and function has been the degree of tightness effect.Snap-fastener adopts embedding grammar to be installed in the medium position of telescopic band, constitutes the conjuncted structure of elongate in shape, and function has been fixedly length effect.The inner position of vamp constituted the conjuncted structure of a shape before rear vamp adopted contact method to be installed in, and function has been steady pin effect.The lower position of vamp constituted the conjuncted structure of slippers shape before preceding sole adopted method of sewing to be connected, and function has been the protection pad effect.Back sole adopts method of sewing to be connected the lower position of rear vamp, constitutes the conjuncted structure of shoe-shaped shape, and function has been the protection pad effect.Press the nail employing and press the medium position that is installed in preceding sole into method, constitute conjuncted structure, function has been a fixation.So just realized the purpose of this utility model.

The advantage of utility model: the utility model and original with shape or purposes big group as feature, the footwear technology of adjustable length or size has been compared an advantage and improvement;

The first, because the utility model has designed sole and vamp after decomposing in technical scheme, so can freely transfer the length of footwear; Thereby the footwear yardage before just more effectively having solved is fixed the problem that can not arbitrarily stretch.

(4) description of drawings:

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the overall structure schematic diagram of expandable-and-contractable shoe of the present utility model;

The numbering of parts explanation in the schematic diagram: vamp 2 uppers of a shoe 3 telescopic bands 4 rear vamps 5 preceding soles 6 are pressed nail 7 back sole 8 snap-fasteners before 1

(5) specific embodiment:

In the optimum implementation of expandable-and-contractable shoe of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:

Its static structure: as shown in the figure, expandable-and-contractable shoe of the present utility model.Mainly by preceding vamp 1, upper of a shoe 2, telescopic band 3, rear vamp 4, preceding sole 5, press nail 6, back sole 7, snap-fastener 8 constitute.The back-end location of vamp 1 constituted the conjuncted structure of Y word shape before upper of a shoe 2 adopted method of sewing to be connected, and function has been firm effect.The back-end location of vamp 1 constituted the conjuncted structure of elongate in shape before telescopic band 3 adopted method of sewing to be connected, and function has been the degree of tightness effect.Snap-fastener 8 adopts embedding grammar to be installed in the medium position of telescopic band 3, constitutes the conjuncted structure of elongate in shape, and function has been fixedly length effect.The inner position of vamp 1 constituted the conjuncted structure of a shape before rear vamp 4 adopted contact method to be installed in, and function has been steady pin effect.The lower position of vamp 1 constituted the conjuncted structure of slippers shape before preceding sole 5 adopted method of sewing to be connected, and function has been the protection pad effect.Back sole 7 adopts method of sewing to be connected the lower position of rear vamp 4, constitutes the conjuncted structure of shoe-shaped shape, and function has been the protection pad effect.Press nail 6 employings and press the medium position that is installed in preceding sole 5 into method, constitute conjuncted structure, function has been a fixation.

Its dynamic structure: in force:

According to mechanics principle, its preceding sole 5 acts on back sole 7 by pressing nail 6, thereby finishes the task of adjusting.According to mechanics principle, its snap-fastener 8 acts on snap-fastener 8 by telescopic band 3, thereby finishes fixing task.So just realized the purpose of this utility model.Thereby the footwear yardage before just having solved is fixed the problem that can not arbitrarily stretch.

Below by using method, the utility model is done more detailed description:

The expandable-and-contractable shoe of this utility model is work like this:

In use, when need are regulated length, transfer to and press nail 6 and untie snap-fastener 8 and just can regulate on demand, according to mechanics principle, its preceding sole 5 is by sole 7 after pressing nail 6 and acting on, thereby finishes the task of adjusting.According to mechanics principle, its snap-fastener 8 acts on snap-fastener 8 by telescopic band 3, thereby finishes fixing task.

Realize that preferred plan of the present utility model is is material with the cloth, utilize the basic equipment of leather shoes factory, take to produce by batch in batches, the demand with the supply daily life so just can realize practical value of the present utility model and economic worth better.
