Abstract
Abstract of the Disclosure A boot comprises a pair of closure flaps in opposed relationship and defining an opening therebetween, at least a portion of each flap near the bottom ends thereof having lace receiving projections integral with the flaps, and a bridge member joining the projections but defining lane receiving openings between the projections, the remainder of the flaps being provided with at least one lane receiving lug on each flap thereof, the lug having a flange defining a lace receiving seat about the lug. The boot is made of plastics material.
Description
The present invention relates to boots, and more particularly, to an improved lacing for boots of the type used for skates or ski boots, e-tc.
Boots used on skates conventionally use eyelets pierced through the edge of the flaps which are normally laced together to tighten the boot against one's foot. Such lacing systems, especially on skate boots ~most ski boots now use buckle systems) have always been less than satisfactory since the skate boots must be laced firmly on the foot, and as the boot is being laced, the portions of the lace which have been tightened should not be permitted to loosen. Furthermore, in the construction of a skate boot, the provision of the eyelets requires manual labour and actually riveting the eyelets in the holes provided in the edge of the flap. The arnount of manual labour required to manufacture boots for skates today puts countries which have a relatively high cos-t of labour at a disadvantage with countries having a low cost of labour, that is, in the manufacture of such boots.
In recent years, the skate boot industry has been evolving into new materials, and the plastics skate boot has become more and more popular. The plastics skate boot, which is made in two parts, an upper and a lower, can be injection molded, and the labour associated with the construction of such boots is decreased compared to the manufacture of a conventional leather boot. However, plastics skate boots still employ the use of conventional eyelets and laces for securing the boot to one's foot. Of course, the time and manual labour required to provide the eyelets in the flaps of the boot is still considerable.
Furthermore, one still has the disadvantages of the conventional lacing systems using eyelets, especially since the lace crosses over underneath the flap as it comes out of and goes into an eyelet, increasing the amount of resistance to being further tightened as the boot is being lacedO
-1- ~
Attempts have been made to overcome the disadvantages inherent with conventional lacesj and an example i5 i~ strated in Canadian Patent 1,001,843, issued December 21, 1976, Anthony Puchnarewicz, inventor. In this paten-t, loops are provided stitched to the edge of a flap for allowing the lace to pas,s therethrough. However, the loops of this patents protrude beyond the flap and, therefore, the opening must be relatively wide since the loops would collide agaînst each other if the flaps extended conventionally. To widen the opening between the flaps detracts from the overall rigidity needed for the boot construction, particularly along the side walls there~f.
Further, special loc~king devices are necessary at the uppermost limit of the flaps to provide the locking of the lace since the loops must be spaced apart and do not appear to provide sufficient friction to allow the laces to be tightened gradually.
It is an aim of the present invention to provide an improved skate which is molded out of plastics material and has lacing devices integrally molded with the flap of the molded plastics skate. It is a further aim of the present invention to provide improved lacing devices ~or boots~
A construction in accordance with the present invention includes a boot comprising a pair of opposed flaps defining an opening therebetween, each flap thereof having spaced-apart lace receiving projections integral with the flap, and each projection having a flange defining a lace receiving seat about the projection.
Stated more specifically the invention includes a boot made of molded plastics ma-terial having a pair of opposed closure Flaps defining an opening therebetween. Each flap has spaced-apart projections molded integral with the flap and each projection has a stem portion. The stem has rounded surfaces defining at least three sides and the cross-sectional dimensions of the ste~ being such as to al.Low smooth sliding of the lace about the stem in an upper flange extends about at least the three sides of the stem defining a lace receiving seat about the projection. The flange extends outwardly an extent greater than the thickne~s of a boot lace and is sufficient to retain a complete loop of :Lacing from slipping off the projection and allowing the lacing to be anchored thereon.
In a more specific embodim~nt, the flanges on adjacent projections on each flap near the bottom are joined forming a bridge and openings between the projections for passing the lace.
Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illust:ration, a preferred embodiment

Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illust:ration, a preferred embodiment
- 2 ~ _ ',i )' thereof, and in which:
Figure 1 is an elevational view of a skate boot embodying the present invention, Figure 2 is a fragmentary elevational view of a detail of the boot in Figure 1, Figure 3 is a fragmentary plan ~iew of the detail of Figure 2, Figure 4 is a fragmentary cross-sectional view along line 4-4 of Figure l; and Figure 5 is a fragmentary cross-sectional view along line 5-5 of Figure 1.
Referring now to the drawings, Figure 1 shows a typical molded skate boot 10 having a lower 12 and an anklet or upper 14 which is hinged to the lower 12. The skate boot 10 is molded in two parts, that is, the lower is molded with the flaps 18 and 20 and a toe 16, while the upper 14 is molded separately.
Suitable hinge devices are provided in the area of the ankle (not shown) for hinging the upper to the lower. Each of the flaps 18 and 20 are provided with lacing devices which are integrally molded to the lower in the area of the flaps. The lacing devices of the present invention include two portionsO The first portion in the lower part of the flaps 18 and 20 near the toe 16 includes, for instance, a pair of projections 22, 24 on flap 18, and 22a, 24a on flap 20. All of the elements on flap 20 are identical to the elements on flap 18, and the numerals corres-ponding to those elemen-ts have the added subscript "a". Only the elements on flap 18 will be described for the purposes of clarity. The projections 2? and 24 are spaced apart and subtend a bridge 26 which extends along the tops of the projections 22 and 24 and terminates in abutment members 30 and 32 which are also in the form of raised projections from the flap 18~ For purposes of enhancing the appearance of the boot, the projections .~
forming the abutments 30 and 32 slope gradually and merge in the side wall of the skate boot.
The provision of the projections 22 and 24 covered by the bridge 26 allows the lace L to be passed about the projec-tions 22 and 24 as well as 22a and 24a in the normal lacing fashion of crossing over the laces with reasonable ease, and at the same time, retaining the lace to the boot. If all of the projections 22 and 24 were similar to the lugs 34 as will be described further, the lace could easily fall from -the boot 10 when the lacing has been unsecured. In the present case, the laces L will be retained on the boot by the bridge 26.
The flaps 18 and 20 are also provided with opposed lugs 34 and 34a. The lug 34 as well as lugs 38 and 42, are of rela-tively sirnilar constructlon as shown in Figures 4 and 5.
~Iowever, the lu~ 34, which lncludes a Elange 36, is :integral wlth the flap 20 while the lugs 38 and 42 are integral with the edge of the upper 14. Each of the lugs 34, 38 and 42 include rounded surfaces, such as shown at 41 in Figure 5. This rounded surface is on the side of the lug 38 which would be in contact with the lace as it passes behind. The flange 36 of lug 34, or as shown in Figure 5, flange 40 of lug 38, defines a seat for receiving the lace L and prevents the lace from flipping over the lug 38 as it is being tightened. The lugs 34, 38 and 42 are similar to metal hook devices presently on certain high boot skates, such as figure skates. However, the diameter of the curved portions 41 of these lugs is large enough that the lace slides reasonably well about the lug without having the reverse fold anchoring action of the smaller diameter metal hooksL
It is known that in lacing a skate it is important that the lower portion of the flaps 18 and 20 be tightly laced and retain the tension while the laces are wrapped a~out the various lugs 34, 38 and 42.
The projections 22 and 24, including bridge 26, can be made such that the bridge 26 is low enough to provide a suit-able amount of friction against the lace and that as the lace is tightened, it will tend -to retain the lc~ce in tha-t positionO
On the other hand, for other types of boots, the opening between the bridge 26 and the flap 18 can he slightly greater to allow easier sliding of the lace L.
Figure 1 is an elevational view of a skate boot embodying the present invention, Figure 2 is a fragmentary elevational view of a detail of the boot in Figure 1, Figure 3 is a fragmentary plan ~iew of the detail of Figure 2, Figure 4 is a fragmentary cross-sectional view along line 4-4 of Figure l; and Figure 5 is a fragmentary cross-sectional view along line 5-5 of Figure 1.
Referring now to the drawings, Figure 1 shows a typical molded skate boot 10 having a lower 12 and an anklet or upper 14 which is hinged to the lower 12. The skate boot 10 is molded in two parts, that is, the lower is molded with the flaps 18 and 20 and a toe 16, while the upper 14 is molded separately.
Suitable hinge devices are provided in the area of the ankle (not shown) for hinging the upper to the lower. Each of the flaps 18 and 20 are provided with lacing devices which are integrally molded to the lower in the area of the flaps. The lacing devices of the present invention include two portionsO The first portion in the lower part of the flaps 18 and 20 near the toe 16 includes, for instance, a pair of projections 22, 24 on flap 18, and 22a, 24a on flap 20. All of the elements on flap 20 are identical to the elements on flap 18, and the numerals corres-ponding to those elemen-ts have the added subscript "a". Only the elements on flap 18 will be described for the purposes of clarity. The projections 2? and 24 are spaced apart and subtend a bridge 26 which extends along the tops of the projections 22 and 24 and terminates in abutment members 30 and 32 which are also in the form of raised projections from the flap 18~ For purposes of enhancing the appearance of the boot, the projections .~
forming the abutments 30 and 32 slope gradually and merge in the side wall of the skate boot.
The provision of the projections 22 and 24 covered by the bridge 26 allows the lace L to be passed about the projec-tions 22 and 24 as well as 22a and 24a in the normal lacing fashion of crossing over the laces with reasonable ease, and at the same time, retaining the lace to the boot. If all of the projections 22 and 24 were similar to the lugs 34 as will be described further, the lace could easily fall from -the boot 10 when the lacing has been unsecured. In the present case, the laces L will be retained on the boot by the bridge 26.
The flaps 18 and 20 are also provided with opposed lugs 34 and 34a. The lug 34 as well as lugs 38 and 42, are of rela-tively sirnilar constructlon as shown in Figures 4 and 5.
~Iowever, the lu~ 34, which lncludes a Elange 36, is :integral wlth the flap 20 while the lugs 38 and 42 are integral with the edge of the upper 14. Each of the lugs 34, 38 and 42 include rounded surfaces, such as shown at 41 in Figure 5. This rounded surface is on the side of the lug 38 which would be in contact with the lace as it passes behind. The flange 36 of lug 34, or as shown in Figure 5, flange 40 of lug 38, defines a seat for receiving the lace L and prevents the lace from flipping over the lug 38 as it is being tightened. The lugs 34, 38 and 42 are similar to metal hook devices presently on certain high boot skates, such as figure skates. However, the diameter of the curved portions 41 of these lugs is large enough that the lace slides reasonably well about the lug without having the reverse fold anchoring action of the smaller diameter metal hooksL
It is known that in lacing a skate it is important that the lower portion of the flaps 18 and 20 be tightly laced and retain the tension while the laces are wrapped a~out the various lugs 34, 38 and 42.
The projections 22 and 24, including bridge 26, can be made such that the bridge 26 is low enough to provide a suit-able amount of friction against the lace and that as the lace is tightened, it will tend -to retain the lc~ce in tha-t positionO
On the other hand, for other types of boots, the opening between the bridge 26 and the flap 18 can he slightly greater to allow easier sliding of the lace L.
