Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Fig. 1 ~ 9, a kind of adjustable size footwear, it comprises:
Sole 1, described sole 1 has half sole 11, spring heel 12 and middle part of the side elastomer 13, and one end of middle part of the side elastomer 13 is connected with half sole 11, and the other end of middle part of the side elastomer 13 is connected with spring heel 12;
Adjuster 3, described adjuster 3 comprises leading portion convergence body 31, back segment cover box 32, control screw rod 33 and swiveling wheel 34, leading portion convergence body 31 is connected on half sole 11, back segment cover box 32 is connected on spring heel 12, and described leading portion convergence body 31 has and the screwed pipe controlling screw rod 33 threaded engagement, described control screw rod 33 is spacing on back segment cover box 32 rotationally, and controlling screw rod 33 is screwed in the screwed pipe of leading portion convergence body 31, to control screw rod 33 by screwing thus to drive leading portion convergence body 31 to move forward and backward relative to back segment cover box 32, described swiveling wheel 34 is fixedly connected with control screw rod 33, and be provided with between swiveling wheel 34 and back segment cover box 32 for limiting the anglec of rotation thus the position-limit mechanism of control half sole 11 distance of stretch out and draw back that control screw rod 33.
As shown in Figure 3, the rear portion of described leading portion convergence body 31 is plugged in back segment cover box 32, and leading portion convergence body 31 can overlap box 32 slide anteroposterior by back segment relatively.
As shown in Fig. 5,6,7, spacing draw-in groove 331 before and after described control screw rod 33 is provided with, spacing card 35 before and after being provided with in described back segment cover box 32, when controlling screw rod 33 and being in place on back segment cover box 32, the spacing card in described front and back 35 is stuck in the spacing draw-in groove 331 in front and back of control screw rod 33, thus makes control screw rod 33 spacing on back segment cover box 32 rotationally.
As shown in Fig. 5,6,8,9, the grab 341 that described position-limit mechanism comprises the front portion being arranged on swiveling wheel 34 and the spacing card 36 of the anglec of rotation be arranged on back segment cover box 32, spacing draw-in groove 361 is provided with in the spacing card of the described anglec of rotation 36, grab 341 is stuck in spacing draw-in groove 361, to be limited the anglec of rotation thus control half sole 11 distance of stretch out and draw back that control screw rod 33 by the restricted rotational movement of grab 341 in spacing draw-in groove 361.
Leading portion convergence body 31 of the present utility model and back segment cover box 32 first combine, then spacing for anglec of rotation card 36 is snapped in back segment cover box 32, then control screw rod 33 and be inserted in swiveling wheel 34, and then control screw rod 33 is rotated in the Centric solenoid modal coil of leading portion convergence body 31, the spacing draw-in groove in front and back 331 and the back segment that control screw rod 33 overlap the position consistency of installing the spacing card 35 in front and back in box, then spacing card 35 before and after snapping in, control screw rod 33 is only rotated in this position, cannot run, finally by swiveling wheel cap 7 on swing pinion 34 rear cover cabinet joint of adjuster 3 front and back.
As shown in Figure 1, it also comprises vamp 4 and middle base fabric 5, and the middle waist portions of vamp 4 and middle base fabric 5 is scalable fabric, vamp 4 together with middle base fabric 5 sewing after bond with sole 1 again.Middle base fabric 5 is divided into 3 sections, and front and rear sections does not have elasticity, and interlude material must be flexible, and three sections of combinations can not have stalk, otherwise impact dress.
As shown in Figure 2, described spring heel 12 has heel intermediate buffer layer 121 and heel flexible substrate 122, heel flexible substrate 122 is bonded in the bottom surface of heel intermediate buffer layer 121, half sole 11 has half sole intermediate buffer layer 111 and half sole flexible substrate 112, half sole flexible substrate 112 is bonded in the bottom surface of half sole intermediate buffer layer 111, and the two ends of described middle part of the side elastomer 13 bond with the front portion of heel intermediate buffer layer 121 and the rear portion of half sole intermediate buffer layer 111 respectively.
Described heel intermediate buffer layer 121 and/or half sole intermediate buffer layer 111 adopt EVA material to make.
Described heel flexible substrate 122 and/or half sole flexible substrate 112 adopt elastomeric material to make.
Adjustable size footwear also comprise shoe-pad.
Middle part of the side elastomer 13 is made up of elastic foldable material, and material must be scalablely have resilience, not easily breaks.
As shown in Figure 3, the rear end of described swiveling wheel 34 is also connected with swiveling wheel cap 7.
By first combination vamp 4 and middle base fabric 5, then sole 1 and whole vamp 4 combination forming, then vamp 4 is driven to extend the effect reaching whole adjusting size by regulating adjuster 3 to make sole extend.
Operation principle of the present utility model is as follows:
When people wears oneself common shoes code applicable, when shoe length direction having as felt a bit tight or loose, by the swiveling wheel 34 of rotary actuator 3, drive control screw rod 33 rotatable elongate of the inside, thus drive the vamp 4 of the whole middle part of the side and middle base fabric 5 and middle part of the side elastomer 13 and then extend or tighten up, thus reach the effect of fitting, particularly children are along with the Fast Growth of pin, and can adjust accordingly, these performances further, footwear when wearing can along with the microvariations of pin micro stretching long, thus more extensively improve comfortableness, on the time of dress, also can bring up to 1 number more for a long time simultaneously, also the durability of dress is just added.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
