Description

FIELD OF THE INVENTION

This invention relates to ice skates, and more particularly to an ice skate assembly. The invention is directed to an improved runner holder and replaceable ice skate runner and tightening mechanism therefore.

BACKGROUND

It is well known to form ice skate assemblies with a provision for the replacement of the runner, also known as the runner.

Commonly, such assemblies comprise a runner holder commonly moulded from a thermoplastic material, having a groove there along within which the runner is received. In accordance with one proposal, the runner is locked to the runner holder by two or more threaded fastener means that pass transversely through the runner and runner holder at longitudinally spaced apart intervals. This arrangement is advantageous in that it permits the rapid replacement of the runner by the use of two very simple tools.

In accordance with the second proposal, the runner is locked to the runner holder by two or more threaded fastener means which pass upwardly through the runner holder. This second means of locking the runner to the runner holder is the choice of many persons, as it permits the runner to be strongly bias into contact with the runner holder. A deficiency in the above-described arrangement is that the replacement of the runner usually necessitates demounting the assembly from the footwear such as to gain access to the threaded fastening means for the release thereof.

Another deficiency in the above-described arrangements is the requirement of using two or more fastener means. The use of two or more fastener means renders the change of a runner cumbersome as well as requiring a longer time to replace a runner.

Consequently there is a need in the industry to provide a runner that can easily be locked to and removed from the runner holder.

In a specific example, the recess 102 is a pivot member as shown in FIG. 4 securely mounted on the wall of the elongated frame 21 . The pivot member may be an integral part of the elongated frame 21 or a separate component mounted on the elongated frame 21 .

FIG. 3 shows a side elevation view of an ice skate runner 30 . In a specific example of the invention, the ice skate runner 30 is a narrow steel strip extending along the length of runner holder 20 . The ice skate runner comprises a lower ice contacting edge 75 , an upper edge 76 generally opposed to the lower edge 75 . The upper edge is adapted to be received by the groove 28 of the moulded runner holder 20 . The ice skate runner has a projection 31 at one end configured to engage the recess 102 of the runner holder 20 . In a specific example, the projection 31 is a hooked portion 31 suitable to engage the pivot member 102 of the moulded runner holder 20 . The ice skate runner has a fastener aperture 78 remote from said runner projection 31 adapted to generally align with the bore 33 of the runner holder 20 . The fastener aperture 78 is generally elliptical in configuration and is suitable for receiving the fastener 32 there through.

As shown in FIG. 4 , when the ice skate runner 30 is positioned with the upper edge 76 in the groove 28 of the runner holder 20 and the runner projection 31 is engaged with the recess 102 of the moulded runner holder 20 , the fastener aperture 78 is essentially aligned with the bore 33 of the runner holder 20 .

The ice skate runner is sharpened on its lower ice contacting edge 75 and provided with protrusions 400 on its upper side 76 . In a specific example of the invention, the ice skate runner has a curved profile, which is accentuated near its extremities 70 and 71 . The ice skate runner 30 is inserted into the longitudinal groove 28 of the runner holder and secured to frame 21 with runner protection 31 , which engages onto recess 102 defining pivot point 74 and front fastener 32 (shown in FIG. 1 ), which locks fastener aperture 78 to frame 21 .

As a variant, the upper edge 76 of the ice skate runner 30 includes a plurality of longitudinally spaced apart protrusions 400 , the protrusions 400 being adapted to stabilise the ice skate runner in the groove 28 of the runner holder 20 . In a specific example, the walls of the runner holder 20 are provided with a plurality of cavities adapted to engage with the protrusions of the ice skate runner.

In a specific example, fastener 100 passes transversely through the fastener aperture 78 of the ice skate runner 30 and the bore 33 of the moulded runner holder 20 . Fastener 100 is adapted to exert a force on the ice skate runner such that the runner projection 31 is engaged on the recess 102 of the runner holder 20 .

Advantageously, fastener 32 allows the ice skate runner 30 to be secured to the runner holder by a sole attachment means.

FIG. 5 b and 5 c show transversal sectional view of the ice skate runner and runner holder assembly. In a first embodiment shown in FIG. 5 b, the fastener 32 includes a threaded nut 200 and a threaded bolt 100 . The threaded nut 200 is imbedded in a wall 206 of the runner holder 20 and the bolt 100 is adapted in operation to pass through the fastener aperture 78 and the bore 33 in the runner holder 20 and be fixedly secured in the nut 200 . In this configuration, the nut 200 may be inserted subsequently to the moulding of the runner holder. A variant, the nut 200 is separate from the runner holder and is secured to the runner holder by the action of the bolt 100 .

In a second embodiment shown in figure 5 c, the threaded nut 202 is imbedded in a wall 206 of the runner holder 20 and the bolt 100 is adapted to pass through the fastener aperture 78 and the bore 33 in the runner holder 20 and be fixedly secured in the nut 202 .

For the purpose of illustration, the force exerted on the ice skate runner is drawn in FIGS. 4 and 5 a as forces 106 and 208 in the planes defined by components 104 108 and 210 104 respectively. The longitudinal component 108 allows the projection 31 to be securely engaged to recess 102 and puts the ice skate runner under tension. The upward component 104 is operative to secure the upper edge 76 of the ice skate runner 30 within the groove 28 of the runner holder 20 . The transverse component 210 is operative to secure the ice skate runner 30 to the wall of the runner holder 20 .

Advantageously, when the fastener with a tapered head passes through the fastener aperture 78 and the bore 33 and is secured in the nut, the tapered head, as shown in FIGS. 4 and 5 a, produces forces 106 and 208 on the runner 30 thereby securing the runner 30 to the runner holder 20 under tension by securely engaging the runner projection 31 and the recess 102 .

Advantageously, the use of a generally elliptical fastener aperture 78 in conjunction with a tapered head allows the tapered head to produce an upward force on the runner 30 thereby securing the runner 30 to the runner holder 20 under tension.

The runner holder comprises an inner wall 204 and an outer wall 206 defining an inner side and an outer side of the ice skate runner 30 . Preferably, but not essentially, the fastener is positioned such that the head of the bolt is on the inner wall 204 the runner holder when in operation. Advantageously, positioning the fastener on the inner wall 204 of the runner holder allows a person wearing skates having the runner holder assembly to conveniently replace the runner 30 without removing the ice skates.

Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, variations and refinements are possible without departing from the spirit of the invention. Therefore, the scope of the invention should be limited only by the appended claims and their equivalents.
