DOUBLE BLADED ICE SKATE
An ice skate having a low profile, dual blade assembly. The blade assembly is affixed to the sole of a boot, and each blade is positioned symmetrically about the center line of the boot, and separated by a lateral distance which is sufficient to avoid a build up of ice/snow between the blades. The blade assembly has a short vertical profile in order to provide a low center of gravity, for example, in the range of forty to sixty percent of the conventional vertical profile.
This disclosure relates to the construction of an ice skate, and in particular, a unique construction having a double blade assembly that is useful for training beginning ice skaters.
A problem for beginning ice skaters is a lack of balance and stability while learning how to skate using a conventional single-bladed ice skate, whether for figure skating or for ice hockey. Others have recognized this problem and offered solutions.
For example, U.S. Pat. No. 2,764,417 discloses several embodiments of ice skates with multiple blades to provide increased stabilization. Each embodiment includes a main central blade, with a pair of stabilizing blades disposed on both sides of the central blade. U.S. Pat. No. 2,920,897 discloses an adjustable attachment to provide auxiliary runners on both sides of the central blade, and likewise, U.S. Pat. No. 3,120,397 discloses an attachment to provide auxiliary runners on both sides of the central blade. U.S. Pat. No. 2,867,445 discloses an attachment to provide a single auxiliary runner disposed to the inside of the central blade (i.e. under the inside portion of the foot).
U.S. Pat. No. 3,199,883 discloses a double bladed skate, wherein each blade is attached to the boot by a complicated bracket assembly. U.S. Pat. No. 4,407,522 discloses a double-bladed attachment device that is clamped onto an existing boot to provide auxiliary runners on either side of the main blade.
Despite these various solutions, it remains desirable to find a simple design that provides a blade arrangement that is comfortable and easy to use for the beginning ice skater.
This disclosure describes a unique blade construction for an ice skating boot, wherein a pair of blades is affixed to the boot in a manner that provides a low center of gravity. This double blade arrangement is particularly useful to provide increased stability for the beginning skater and thereby ease the process of learning to skate.
The heel platform 24 is preferably a rigid flat piece of steel having mounting holes 25, and similarly, the toe platform 26 is a rigid flat piece of steel having mounting holes 27. The mounting holes 25, 27 are provided so that the blade assembly 20 can be fastened by screws (not shown) into the bottom of boot 10. Other known attachment methods could also be used, for example, pop rivets, or alternatively, the platforms 24, 26 could be integrally molded as part of the boot, like a hockey style boot, as further discussed below.
Note that the heel platform 24 and toe platform 26 are welded between the stanchions 22 of blades 21, rather than on top of the stanchions, in order to minimize the vertical profile of the blades. In fact, when compared to a conventional skate, rather than changing the vertical geometry of the blade itself, the present embodiment achieves a lower profile by having shorter stanchions.

Different boot sizes will generally not require different values of H and W. However, it is possible that a very small child's size could benefit from a slight reduction in the value of W, and likewise, that a very large adult size could benefit from a slight increase in the value of W, which would also lead to larger heel and toe platforms.

In general, those skilled in the art to which this disclosure relates will recognize that many changes in construction and materials as well as widely differing embodiments will suggest themselves without departing from the spirit and essential characteristics of this disclosure. Accordingly, the disclosures and descriptions herein are intended to be illustrative only, and not limiting, of the scope of the invention, which is set forth in the claims.
Claims
1. An ice skate, comprising:
- a boot having a sole;
- a blade assembly coupled to the sole of the boot, including a pair of blades each positioned symmetrically about a longitudinal center line of the boot, said blade assembly having a short vertical profile in order to provide a low center of gravity.
2. An ice skate as in claim 1, wherein the vertical profile is approximately half that of a conventional ice skate.
3. An ice skate as in claim 1, wherein the vertical profile is reduced by approximately forty to sixty percent compared to a conventional ice skate.
4. An ice skate as in claim 1, wherein the vertical profile is approximately two to three centimeters.
5. An ice skate as in claim 1, wherein the pair of blades is separated by a lateral distance which is sufficient to avoid a build-up of ice/snow between the blades.
6. An ice skate as in claim 5, wherein the lateral distance is a few centimeters.
7. An ice skate as in claim 5, wherein the lateral distance is approximately 3.6 centimeters.
8. An ice skate as in claim 1, the blade assembly further comprising a toe platform and a heel platform, wherein the blades are rigidly affixed to the toe and heel platforms, and the toe and heel platforms are fastened to the boot.
9. An ice skate as in claim 1, wherein the blade assembly is integrally formed with the boot.
10. An ice skate, comprising:
- a boot having a sole;
- a blade assembly coupled to the sole of the boot, said blade assembly comprising a toe platform, a heel platform, and a pair of blades affixed to the toe and heel platforms, wherein each blade is positioned symmetrically about a longitudinal center line of the boot, said blade assembly having a short vertical profile in order to provide a low center of gravity.
11. An ice skate as in claim 10, wherein the blade assembly is affixed to the toe and heel platforms by at least two stanchions, said stanchions being sized to provide said short vertical profile.
12. An ice skate, comprising:
- a blade assembly integrally molded with a boot, said blade assembly including a pair of blades each positioned symmetrically about a longitudinal center line of the boot, said blade assembly having a short vertical profile in order to provide a low center of gravity, wherein the pair of blades is separated by a lateral distance which is sufficient to avoid a build-up of ice/snow between the blades.
