ABSTRACT
A relatively low cost injection moulded ice skating boot in which a relatively rigid outer boot is moulded around the upper peripheral flanges of a conventional prefabricated skate blade support assembly, so as to form a lightweight one piece outer skate boot with integral skate blade support assembly.
A relatively low cost injection moulded ice skating boot in which a relatively rigid outer boot is moulded around the upper peripheral flanges of a conventional prefabricated skate blade support assembly, so as to form a lightweight one piece outer skate boot with integral skate blade support assembly.
Description
~09706~
This invention relates to ice skating boots and more particularly to thermoplasti.c injection moulded ice skating boots.
Ice skat~ng boots have traditionally been made of leather although in recent years manufacturers have turned to relatively r~gid in~ection moulded therm.oplastic outer boots, with a soft flexible and resilient inner boot lining to provide comfort and fit, in order to reduce ~aterial and labour costs.
The skate blade is generally affixed to the sole of the boot, whether leather or plasti.c, by means of rivets or screws. This not only requires considerable skilled labour but also entails the risk that the skate will become loose or even detached from the boot, requiring that the boot be repaired and the blade replaced. It has been suggested that a skate blade may be affixed in a longitudinally extending plastic member wh.ich is then affixed in the boot by injection moulding of flexible and wear resistant thermoplastic material therearound. Attention ~s directed to Canadian Patent 1,026,781, issued February 21, 1978 to Lu~gi ~ghemo for an ice skating boot comprising a boot 20 upper and boot sole having a downwardly projecting longitudin-ally extending ~ember wherein a sk~ting blade is embedded and anchored by means of projections or recesses at its upper part, the periphery of the sole extending upwardly to encompass the lower part of a foot when the boot is in use, the upwardly extend~ng part being enclosed on the outside by the boot upper and the longitudinally extending member having transverse holes, the upper ends of which are covered by the boot upper. While the ~ghemo solut;on to the problem solves, in large measure, the problems of skate attachment and prevention of skate . . . . . .
.
~097061 detachment, problems still remain in that provision of a special boot sole having a downwardly projecting longitudin-ally extending member requires the use of special and very expensive dies in order to produce the specialized shape required and furthermore, as there is a considerable over-lapping of material between the sole and the upper, the boot is relatively heavy and requires considerably more material than is believed necessary.
It is an object of the present invention, therefore, to provide a relatively low cost, injection moulded plastics material skate boot having a skate blade and support therefor integrally moulded therewith, which is light in weight and which employs a standard skate blade and support assembly designed for conventional rivet or screw attachment to a skate boot. Provision of additional and expensive dies to produce the skate support member is thereby avoided and a simple, secure lightweight boot may be produced in a single moulding operation.
Thus, by one aspect of this invention there is provided an ice skating boot comprising an integrally moulded, relatively stiff plastics material boot upper and sole~ and a prefabricated, rigid, downwardly projecting and longitudinally extending blade support member having a skating blade rigidly secured along a lower marginal edge thereof; said support member being firmly embedded, along an upper marginal edge thereof in said sole during moulding thereof.
The invention will be described in more detail here-inafter with reference to the accompanying drawings in which:
Figure 1 is a side elevational view of a blade affixed in its longitudinal extending member according to the 1~97061 prior art;
Figure 2 is a side elevational view of a blade affixed in an injection moulded longitudinal member in standard manner for use in the present invention;
Figure 3 is a side sectional view of a boot with integrally moulded blade according to the present invention;
Figure 4 is a sectional view taken along the plane IV-IV of Figure 3;
Figure 5 is a sectional view taken along the plane V-V of Figure 3;
~igure 6 is a sectional view taken along the plane VI-VI of Figure 3; and Figure 7 is a plan view taken along the plane VII-VII of Figure 3.
Figure 1 shows a thermoplastic boot sole 1 having a downwardly projecting longitudinally extending member 2 with a skate blade 3 embedded therein, according to the Aghemo Canadian Patent 1,026,781 referred to above. In order to produce a boot sole 1 which extends upwardly to encompass the .lower part of the foot, it will be appreciated that a large ~ series of relatively complex moulds is required in order to : accommodate both left and right feet in all standard foot sizes, even though the skate 3 may only be made in 2 or 3 different sizes. In order to mould an upper over the sole 1 a second series of moulds is also required, and it will be appreciated that this represents a very considerable investment in mould inventory.

The support assembly 5 has generally V-shaped ho:Llow fore and aft sections, 6 and 7 respectively, having peripheral flanges 8 and 9 provided with a plurality of holes 16 (Figure 7) for insertion of rivets or screws to attach the assembly to the sole of a prefabricated boot of either the conventional leather or more modern injectionmoulded variety.
It will be understood, however, that the specific shape of the assembly 5 is not critical to the present invention in that alternative materials and forms of assembly 5 may be employed.
Figure 3 shows an injection moulded boot of the present invention in which a relatively stiff, but slightly flex-ible, plastics material boot 10 is injection moulded around the peripheral flanges 8 and 9 of the skate assembly 5 of Figure 2.
The boot 10 includes an upper 11, which may be provided with eyelet holes 12 and be of any convenient vertical height, and a sole portion 13. Sole 13 is, of course, continuous around the instep portion as shown in Figure 6 but at the toe and heel (fore and aft portions) the sole is moulded around the peripheral flanges 8, 9 of the skate assembly 5, as seen most clearly in Figures 4 and 5, while leaving the V-shaped hollow sections 14, 15 free of material. The hot plastia material flows into and through the holes in the peripheral flanges 8,9 and thereby effects a secure mounting or anchoragq for the skate assembly. The hot plastic material is prevented from entering the spaces 14, 15 by means of contoured bosses (not shown) provided on the inner core or male portion of the 109706~
injection mould. It will be appreciated that standard male moulds may be employed in the productlon of the boots of the present invention and the contoured bosses merely secured thereto as required. It is not, therefore, necessary to provide an extra series of male moulds especially for production of the present boots in plants which may be producing boots of various other designs and models.
Upon removal of boots of the present invention from the mould it will be appreciated that the sole 13 has a pair of cavities 14, 15 therein. These cavities are desirable to reduce weight and limit the quantity of plastics material required but of course they must be at least partially covered prior to insertion of the now conventional soft flexible inner liner (not shown). The covering may be effected by insertion of a relatively rigid, flat inner sole covering either the entire sole area or a portion thereof over the cavities. In the alternative, a lightweight rigid plastic foam shape or prefabricated lattice frame may be inserted in the cavities in order to support the inner liner when placed in position.
While thermoplastic materials are preferred in boots of the present invention, it will be appreciated that modern injection ; moulding technology also contemplates the use of thermosetting plastics material which could equally well be used in the boot9 of the present invention.
