BACKGROUND OF THE INVENTION:
(a) Field of the Invention
[0001] The present invention relates to an auxiliary skate blade for attachment to a skate
blade already secured to a skate boot, and preferably, but not exclusively, to an
auxiliary ice skate blade which is substantially longer than the blade which is secured
to the boot.
(b) Description of Prior Art
[0002] It is known to affix auxiliary devices over an ice skate blade to permit the ice
skate to be converted into a shoe lower surface whereby one can walk with the skate
blade on floor surfaces or other surfaces without damage to the surface. Also, ski
type runner attachment devices are known for securement to the skate blade support
to convert the skate blade into a ski surface for displacing oneself on snow.
SUMMARY OF THE INVENTION:
[0003] The present invention relates to a novel auxiliary skate blade which is attachable
to a skate blade already secured to a boot to convert the skate into a different type
of skate such as a racing type skate which is popularly utilized as a skate for excursions
on lengthy ice surfaces.
[0004] A feature of the present invention is to provide an auxiliary skate blade which is
easily securable and detachable to a skate blade secured to a skate boot.
[0005] Another feature of the present invention is to provide an auxiliary ice skate blade
which is light, compact, and easily transportable, economical to manufacture, and
easy to use.
[0006] According to the above features, from a broad aspect, the present invention provides
an auxiliary ice skate blade for attachment to a skate blade secured to a skate boot.
The auxiliary skate blade comprises a narrow elongated blade having an ice contacting
edge and an upper elongated slot in a blade receiving upper part thereof for receiving
at least a lower edge portion of the skate blade secured to the skate boot. Fastening
means is provided to rigidly retain the skate blade of the boot in the slot.
BRIEF DESCRIPTION OF THE DRAWINGS:
[0007] The preferred embodiment of the present invention will now be described with reference
to the accompanying drawings in which:
FIGURE 1 is a side view of a conventional skate showing the auxiliary ice skate blade
secured to the blade thereof,
FIGURE 2 is a front view with the auxiliary ice skate blade, and the skate blade secured
to the boot shown in cross-section, and
FIGURE 3 is an enlarged cross-section view of the auxiliary skate blade showing how
it is attached to a skate blade of a conventional skate.
DESCRIPTION OF PREFERRED EMBODIMENTS:
[0008] Referring now to the drawings, and particularly to Figure 1, there is shown an ice
skate 10 comprising a boot 11 to which an ice skate blade 12 is secured by a blade
support structure 13. The auxiliary ice skate blade 14 of the present invention is
herein shown secured to the skate blade 12. The auxiliary skate blade comprises essentially
a narrow elongated blade 15 having an ice contacting edge 16 and an attachment means
17 in an upper part of the blade 15 for detachable securement to the skate blade 12.
[0009] As herein shown, the auxiliary skate blade 14 is substantially longer than the ice
skate blade 12 which is secured to the boot 11 whereby to convert the standard type
of hockey ice skate 10 to a racing type skate. The substantially longer length of
the auxiliary-blade permits one to-attain higher speeds when skating and is less tiring
and therefore desirable for long skating excursions.
[0010] Referring now additionally to Figures 2 and 3, there is shown the construction of
the attachment means 17. It is constituted by a blade support member 18 which may
be formed integral with the narrow elongated blade 15. However, as herein shown, the
blade support member 18 is constituted by a molded piece formed of rigid-material,
such as rigid plastics, aluminum or other suitable materials. The blade support member
18 has a lower blade retention slot 19 for receiving the narrow elongated blade 15
therein. Suitable means is provided to secure the blade 15 within the retention slot
19 and it may be constituted by the use of adhesives, or. fasteners extending through
the lower part of the support member 18 and the upper part of the blade 15, as is
well known in the art.
[0011] An upper elongated slot 20 is provided in the upper part of the support member 18
and extends in axial alignment with the blade 15 whereby to receive at least a lower
edge portion of the skate blade 12 which is secured to the skate boot 11. Fastening
means 21, herein constituted by two or more spaced apart screw-type fasteners 22,
are provided in a side wall 23 of the upper part of the blade support member 18 adjacent
the slot 20. The screw-type fasteners 22 have a threaded shaft portion 24 in threaded
engagement with respective threaded bore 25 extending through the side wall 23. The
free end of the threaded shaft 24 constitutes a clamping surface 26. The other end
of the threaded shaft portion 24 is provided with a finger gripping outer end 27 to
impart rotation and torque to the fastener whereby the clamping surface 26 of each
fastener will apply a retention axial force against the side face 27' of the blade
12 which is positioned in the slot 20 to clamp the blade 12 between the inner side
wall 28 of the slot 20 and the clamping surfaces 26. Thus, the blade 12 is rigidly
and immovably secured in the slot 20.
[0012] It is within the ambit of the present invention to provide any obvious modifications
of the embodiment described herein, provided such modifications fall within the scope
of the appended claims. For example, the inner side wall 28 of the slot 20 may have
a rough surface texture or be provided with small vertical ribs therein to provide
better friction retention with the side face of the skate.blade positioned thereagainst.
Also, the fasteners 21 may be of a different construction than screw-type and could
be, for example, wedge clamps. Also, the auxiliary blade need not be longer than the
' conventional blade secured to the skate boot and could serve for the purpose of
providing a sharp lower edge to the skate blade secured to the boot when that latter
blade contacting edge becomes worn.
