On arrowband 30, shell 12 and inner liner 22, punch 32 then.In case punching, hole 32 reinforcement by metal rivet 34 or any appropriate device, this is known in footwear art.
Then tongue portion 24 and toe-cap 14 are connected on the shell 12.In a non-restrictive example, toe-cap 14 and flap 24 be just assembling in advance before being installed on the shell 12.Flap 24 is connected on the toe-cap 14 and upwards extends back from toe-cap and is used to hide the instep of pin F.The leading edge of flap 24 can be sewn directly on the toe-cap 14 or can optional mode well known in the prior art fix.Toe-cap 14 can be sewn onto by the both sides with toe-cap 14 on the sidepiece 40,42 and be fixed on the shell 12.
Shoe tree can insert in the cavity of shell 12 to finish the manufacturing of boots.Shoe tree makes shell 12 keep its shape when skirt section 56,58 folds and couples together.Shown in Fig. 4 and 6, skirt section 56,58 can couple together by the suture 59 of center line along the longitudinal.As indicated previously, skirt section 56,58 can couple together by the multitude of different ways that does not deviate from main idea of the present invention, for example by gluing, heat bonding, rolling, slide fastener, order and close and projection/groove device.In case coupling together securely, skirt section 56,58 obtained its final form to form sole 60 and footwear boots, can grind with part smooth footwear boots lower surface slightly and a smooth surface is provided sole 60, can pass through adhesive, rivet, screw, nail or any erecting device well known in the prior art at this surface upper tool post 16 and install.The outsole of an outsole 31 as shown in Figure 4 can be connected on the sole 60, and knife rest 16 is installed on the outsole 31 then rather than directly is installed on the sole 60.As indicated previously, if being rigidity of a selectable unit (SU) and sole 60, outsole 31 enough can no longer need.
Alternatively, the insole of an insole 29 as shown in Figure 4 can be located at 56,58 inboards, skirt section.As indicated previously, insole 29 is selectable unit (SU)s.In case finish the assembling of top footwear boots, just top footwear boots be placed upside down on a shoe tree machine.At first along its neighboring in the applying glue of the bottom surface of insole 29.Skirt section 56,58 is then on the bottom surface that folds into insole 29 on the shoe tree.In case folding, skirt section 56,58 has formed sole 60, and sole 60 bonds on the insole by the viscose glue that applies on the bottom surface of insole 29 in advance.Further with skirt section 56,58 along insole 29 peg, stitching or bonding necessary mechanical grasp to be provided and to allow viscose glue to be arranged on suitably between sole 60 and the insole 29.In case sole 60 is connected on the insole 29 securely and the footwear boots have obtained its net shape, can carry out slight grinding with the lower surface of the smooth footwear boots of part and a smooth surface is provided to sole 60, outsole 31 or knife rest 16 can pass through adhesive, rivet, screw, nail or any other erecting devices well known in the prior art and install on this surface.
A footwear bed 28 can insert in the shell 12 so that be placed on the sole 60 that is formed by two skirt sections 56,58.In this way, footwear bed 28 has hidden the seam of two skirt section 56,58 intersections, and perhaps under the situation of shell 70, footwear bed 28 has hidden the seam of a skirt section 84 and a sidepiece intersection.
Footwear bed 28 has a upper surface 120 and a gasket walls 122.This upper surface 120 is used for admitting the foot plate surface PS of pin F, and this gasket walls 122 projects upwards from this upper surface, is used for part to hold heel H and extend to the center line of pin F.
Be to be understood that, footwear boots 10 can comprise roller bearing chassis, the roller bearing chassis that is installed on the outsole 31 that hides sole 60 on the bottom surface that is installed to sole 60, perhaps one be installed on the sole 60, be used to walk, trek, the outsole of pleasure trip on foot, cross-country skiing, rugby, basketball or football.
Should not explain the description of embodiment above, because other variant, changes and improvements are possible in main idea of the present invention and scope in restrictive mode.Scope of the present invention is limited by attached claim and equivalent thereof.
