Boot with hinged upper

A hinged boot comprising:

• a vamp shell having an attachment section,
• an upper shell having an attachment section which overlaps the vamp attachment section,
• hinge means protected from external adverse conditions for interconnecting the attachment sections to allow pivoting forward and rearward movement and sideways rocking movement of the upper shell relative to the vamp shell, the protected hinge means including
• a slide frame located between the vamp section and the upper section, the frame having a slide aperture,
• a pivot pin having an enlarged head of greater cross-section than the slide aperture and an extending neck of smaller cross-section than the slide aperture and extending therethrough,
• means connecting the slide frame to one of the attachment sections with the overlapping upper shell extending down over and covering the slide frame, and
• means connecting the pivot pin to the other of the attachment sections.

A hinged boot comprising:

• an upper shell formed of a relatively rigid plastic material,
• a vamp shell formed of a relatively rigid plastic material,
• hinge means interconnecting the upper shell to the vamp shell for pivotal forward and rearward movement of the upper shell,
• a replaceable sole formed of a relatively resilient material and having a base with a surrounding lip, and
• adhesive means forming a rupturable seal for connecting at least the lip of the replaceable sole to the vamp shell.

A hinged boot comprising:

• a vamp shell having an attachment section,
• an upper shell having an attachment section,
• one of the attachment sections having an elongated depression therein of a length greater than its width,
• a slide frame fixedly attached to said one of the attachment sections and having an elongated slot aligned with the elongated depression so that the length of the elongated slot is parallel with the length of the elongated depression,
• a pivot pin having an enlarged head slidably captured by the frame within the elongated depression and a reduced neck extending through the elongated slot to allow the pivot pin to move longitudinally within the elongated slot, and
• means connecting the neck of the pivot pin to the other of the attachment sections to allow pivoting forward and rearward movement and sideways rocking movement of the upper shell relative to the vamp shell.

A hinged boot comprising:

• a vamp shell having an attachment section,
• an upper shell having an attachment section,
• hinge means interconnecting the attachment sections to allow pivoting forward and rearward movement and sideways rocking movement of the shells, including
• a pivot pin connected to one of the attachment sections and having an enlarged head and a neck of smaller cross-section extending therefrom, and
• a slide frame fixedly attached to the other of the attachment section and having a slide aperture of greater extent in all directions than the cross-section of the extending neck and of lesser extent in at least one direction than the extent of the enlarged head to cause the pivot pin to float in the slide frame and have no fixed axis.
