BRIEF SUMMARY
TECHNICAL FIELD AND BACKGROUND ART
This invention relates to a shoe construction of the kind described in U.S. Pat. No. 4,196,485 in which a heel comprises a plurality of pins the upper ends of which are attached to the sole of the shoe.
In the arrangements disclosed in the above patent, the upper ends of the pins are fixed to an attachment plate which is secured to the lower surface of the heel portion of the shoe sole.
Such arrangements are eminently suitable for use with shoes having a sole moulded of plastics material, particularly nylon, but are unsatisfactory for use with soles of leather. The object of the present invention is to provide a means for attaching such pins to a leather sole, particularly a laminated leather sole.
DISCLOSURE OF INVENTION
The present invention broadly resides in a shoe sole and heel construction whereby a heel comprising a plurality of pins each having an enlarged head at the upper end thereof may be attached to a sole member, characterised in that each pin is attached to the sole member by means of a socket having a cavity therein for the reception of said enlarged head, said cavity opening to the outer face of said socket by a first passage accommodating the shank of said pin and being of a cross-section smaller than said head, said cavity opening to an inner face of the socket by a second passage through which said shank and said head may be passed to locate said head within said cavity, and means fastening said socket to said sole.
Preferably the screw fastening means comprises a screw fastening device passing through the sole member for engagement with a threaded portion of the cavity.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates in side elevation a shoe embodying the present invention.
FIG. 2 is an end elevation of the shoe illustrated in FIG. 1.
FIG. 3 is a detailed cross-section of the pin fastening arrangement employed in the shoe of FIG. 1.
FIG. 4 shows a pin fastening arrangement in accordance with the present invention, applied to a shoe having a synthetic sole.
BEST MODE OF CARRYING OUT THE INVENTION
The shoe illustrated in FIGS. 1 to 3 comprises a laminated leather sole consisting of a lower laminate 10 and an upper laminate 11. The heel of the shoe comprises a plurality of pins 12 each having an enlarged head 13, only one of these pins and its associated fastening elements being illustrated in the fragmentary cross-section view of FIG. 3. Each pin 12 is fixed to the shoe sole by the location of its head 13 within a cavity 14 in a pin head socket 15. This pin head socket is provided with a generally hemispherical outer surface and a passage 16 through which the pin extends, the passage 16 providing a small clearance for the diameter of the pin.
The pin head socket 15 engages the outer surface of the lower sole laminate 10 by means of a flange 17, and is provided with a portion 18 which extends within a circular aperture 19 in the lower sole laminate. Within this portion 18 the side wall of the cylindrical cavity 14 is threaded for engagement with a counter-sink headed screw 20.
Between the sole laminates 10 and 11 there is located a metal tongue 21 fixed to the laminates by adhesive. This tongue extends over the major portion of the length of the sole to impart a desired degree of stiffness to the sole. The tongue 21 is provided with a counter-sunk aperture 22 for reception of the head of the screw 20. Between the lower end of the screw 20 and the end 13 of the pin 12, there is provided a pad 23 of deformable material.
The illustrated structure is assembled by passing the heel pins 12, lower end first, through the cavity 14 and the passageway 16 and fixing the lower ends of the pins in the lower heel member 24 with the aid of a suitable jig. A deformable pad 23 is then placed within each pin head socket cavity and each socket is assembled with the lower sole laminate 10 and the metal tongue 21 by means of the screw 20. As each screw 20 is driven home the pin head socket 15 is drawn tightly against the lower surface of the lower sole laminat
