Description

A kind of scalable footwear

Technical field

The present invention relates to a kind of scalable footwear.

Background technology

The shoes of producing at present all are the footwear of formulating various regular length sizes according to people's sole size; Like this for will produce the various footwear that are of different sizes; Many production equipments and operation have been increased; And people will remove to try to be fit to the footwear of own sole length size when buying footwear, inconvenience is arranged more, will buy the various footwear that are of different sizes as giving according to each individual sole length difference when the personnel of group are unified to join footware; And student and their the sole length of children of the stage of growth is constantly increased, the footwear of buying soon cause waste with regard to not wearing because size fixes; Also have, in the active procedure, you are more and more tighter through regular meeting's sensation shoes out of doors, and that is because the cause that your pin expands.At this moment, hope that very shoes can extend, therefore be necessary the existing fixedly footwear of size are improved.

Summary of the invention

Task of the present invention is to overcome the existing fixedly above-mentioned shortcoming of footwear of size, and a kind of scalable footwear are provided.The objective of the invention is to buy so existing: described scalable sole comprises sole and vamp; Sole comprises sheet under symmetrical sole sheet one sole of two plate shapes; Sole last slice, the adjuster of packing between sheet and the sole last slice under the sole, described adjuster are provided with regulates box, adjusting lever, push rod; One end of adjusting lever has and is prong, and opening part two outsides of prong are provided with tooth, and the corresponding box inboard of regulating box is provided with tooth bar; The tooth of opening part two outsides of prong meshes with the tooth of the inboard tooth bar of the box of regulating box, and the centre of prong is fluting, and the corresponding interior middle part of box of regulating box is provided with chute; Prong be recessed at chute above, be provided with a sliding convex head below the bar head of the groove width push rod of the wide fluting less than prong of the bar of push rod, regulate the box face and be provided with lid; Lid a chain for binding criminals nail is fixed in to be regulated on the box face; The front portion of sole sheet is provided with grooving, is provided with protruding one fixing plush copper in the grooving, and the rear portion of sole sheet is provided with the corresponding big or small groove of box of regulating; It between the rear portion of sole sheet and the front portion empty shape rhombus combination in telescopic more than two; In the inside one side of empty shape rhombus combination be provided with the corresponding wide groove of box adjusting lever bar of regulating, an end of adjusting lever is provided with the collar, the collar is inserted on the front portion of sole sheet establishes protruding fixedly plush copper in the grooving; And be fixed in the groove of grooving and rhombus combination, combine fixing behind the sole sheet glue of two plate shapes symmetry.

Compare with prior art; The adjuster of packing between sheet and the sole last slice under the scalable footwear sole of the present invention; Can freely adjust the length of scalable footwear, can formulate the footwear of various fixedly sizes according to people's sole size again in the production, and can unify to produce scalable footwear according to people's sole size; Thereby reduce production equipment and operation; Improved production efficiency, and people again need not remove to try footwear everywhere for can't buy the footwear that are fit to own sole length size when buying footwear, and the student in the stage of growing up and children they yet can not fix to wear and cause waste because of just buying soon footwear size.

The specific embodiment

Specific embodiment below in conjunction with accompanying drawing further specifies the present invention.(but not being limitation of the present invention).

Be the structural representation of a specific embodiment of the present invention shown in Fig. 1-6, like figure, scalable footwear of the present invention comprise sole 21 and vamp 22, and sole 21 comprises the sole sheet of two plate shapes symmetry; Sheet 1, sole last slice 24 under the sole, the adjuster 25 of packing between sheet 1 and the sole last slice 24 under the sole, described adjuster are provided with regulates box 4, adjusting lever 2, push rod 3; One end of adjusting lever has prong 5, and opening part two outsides of prong 5 are provided with tooth, and the corresponding box inboard of regulating box is provided with tooth bar 7; The tooth of opening part two outsides of prong meshes with the tooth of the inboard tooth bar of the box of regulating box, and the centre of prong is fluting 8, and the corresponding interior middle part of box of regulating box is provided with chute 9; The fluting 8 of prong is provided with a sliding convex head below the bar head of the groove width push rod of the wide fluting 8 less than prong 5 of the bar of push rod 3 on chute 9, sliding convex head embeds chute; Then push rod 3 can be advanced in the fluting 8 of prong along chute 9, regulates the box face and is provided with lid 10, with a chain for binding criminals nail secured adjusted box 4 and lid 10; The front portion of sole sheet is provided with grooving 11, establishes protruding fixedly plush copper 12 in the grooving, and the rear portion of sole sheet (being corresponding people's heel) is provided with the corresponding groove 14 of regulating the box size; So that regulating box is placed in one; Be empty shape rhombus combination 13 in telescopic more than two between the rear portion of the sole sheet of scalable footwear of the present invention and the front portion, the inside one side of interior empty shape rhombus combination is provided with the corresponding wide groove of box adjusting lever bar of regulating, like the groove on the sheet under the sole 15; One end of adjusting lever is provided with the collar 16; The collar is inserted in the fixedly plush copper 12 on the front portion of sole sheet, and is fixed in the groove of grooving and rhombus combination, and the sole sheet gummed of two plate shapes symmetry is fixing.

Vamp 22 can adopt the easy-to-draw buckle structure 23 that is prone to regulate degree of tightness.

During use; Push rod is detached the fluting of prong along chute; From footwear rhombus combination compressing adjusting lever prong, can make the tooth position of engagement displacement of adjusting lever prong and the inboard tooth bar of the box of regulating box, regulate after finishing with push rod push along chute in the fluting of prong and make the adjusting lever prong with the fixing no longer displacement in the tooth position of engagement of the inboard tooth bar of the box of regulating box the fixing length of footwear; Thereby make sole extending or shorten, scalable footwear.

Below only be practical implementation example of the present invention, all similar changes of doing according to above-mentioned design ought to belong to scope of the present invention.
