Manufacturing method for an ice skate blade
Abstract
The present invention relates to the manufacturing method of an
ice skate blade. The blade originally shaped as cylinder is
processed by a rolling machine and gradually being rolled into a
blade with thinner upper portion and wider lower portion. A
plurality of through holes with equi-distance in between are
provided on the upper portion of the blade which is curved upward
at both ends. Finally, a layer of light and rigid polymeric resin
material is provided for covering the upper portion of the blade to
complete the blade having upper and lower matching sections.

Claims
1. An ice skate blade comprising: a blade holder and a blade,
wherein said blade is manufactured by gradually process an
originally cylinder shaped steel blade into a rolling machine with
multi sectional process; upper portion of said blade is clipped and
rolled into slightly thinner width at the first section and then
clipped tighter and rolled into much thinner but suitable width in
the following rolling sections to form a blade with wider lower
portion and thinner upper portion; a plurality of through holes are
provided on the upper portion of said blade with suitable spaced
equi-distance in between and said blade is curved upward at both
ends; and thinner upper portion of said blade with through holes
thereon is covered with a layer of light and rigid polymeric resin
material forming said blade having upper and lower sections.
2. An ice skate blade according to claim 1, wherein said through
holes on upper portion of said blade could also be replaced with a
plurality of protrusions with suitably spaced equi-distance in
between.
Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an ice skate blade, more
particularly to the manufacture method of the blade with being
gradually rolling pressed by a rolling machine.
[0003] 2. Description of Related Invention
[0004] Referring to FIG. 1 of the drawing, a conventional skate
blade of which the steel blade (1) is originally cut off into shape
by machine increases the weight of the blade.
[0005] As for FIGS. 2 and 3 of the drawing, the U.S. Pat. No.
6,761,363 issued on Jul. 13, 2004 to Richard J. Fask et al, an
improvement structure of the blade is described, wherein the blade
(4) is initially milled into shape and two elongated thinner sides
(2) of the blade (4) are forming by milling machine. Further,
through holes are formed and finally the blade (4) is covered by a
layer of polymeric resin material (3) for reducing the weight of
the whole blade. However, the method of material replacement still
suffers from some disadvantages as follows.
[0006] Firstly, it consumes much more time to form two elongated
thinner sides (2) of the blade (4) by milling machine after the
blade (4) is milled into shape, especially the milling process
could only be practiced uni-laterally at one time which means it
would take twice the time to complete the process.
[0007] Secondly, the milling process needs to be practiced after
the blade (4) is cut into shape which means that a large amount of
material would be cut off causing much waste of the material and
the cost.
[0008] Thirdly, the elongated thinner sides (2) are formed by
removing a large amount of steel material and such process would
harm the nature of the steel material and lessen the rigidity of
the blade (4)
SUMMARY OF THE PRESENT INVENTION
[0009] In view of the foregoing disadvantages, the present
invention relates to an ice skate blade, wherein the blade of the
preferred embodiment is molded by multi sectional gradual process
by rolling pressing machine to form the blade into a structure of
wider lower portion and thinner upper portion. A plurality of
through holes are formed by machine and then the blade is curved
upward at both ends. Further, the blade is covered by a layer of
light and rigid polymeric resin material to reduce the whole
weight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] Referring to FIGS. 4-8 of the drawings, the present
invention includes a blade holder (50) and a blade (40), wherein
the blade is formed by processing an originally cylinder shaped
blade (10) by a rolling machine (30) as shown in FIG. 4. With multi
sectional process of rolling molding, upper portion of the cylinder
shaped blade (10) is clipped and rolled slightly into thinner width
at the first section, and then clipped tighter and rolled into much
thinner but suitable width in the following rolling sections to
form a blade with wider lower portion and thinner upper portion. A
plurality of through holes (101) with suitable spaced equi-distance
in between are provided on the thinner upper portion of the blade
(10) which is curved upward at both ends. A layer of light and
rigid polymeric resin material (20) is used for covering the
thinner upper portion of the blade (10) to form the blade (10) with
upper and lower sections.
[0019] Referring to FIG. 8, the example of preferred embodiment of
the present invention, wherein the through holes (101) on the
thinner upper portion of the blade (10) can also be replaced with a
plurality of protrusions (112) with suitable spaced equi-distance
in between. The advantages of the present invention are as
following:
[0020] Firstly, the blade (10) is molded by the rolling machine
(30) with faster speed. Preferably, the upper portion of the blade
(10) is rolled into thinner width by gradually passing the roller
machine (30) until a wider lower and thinner upper portion are
formed.
[0021] Secondly, the blade (10) which is originally shaped as
cylinder steel is directly processed into the rolling machine (30)
without being milled by machine so as to prevent wasting material
and fastening the manufacturing process.
[0022] Thirdly, the blade (10) is formed by the rolling machine
(30) without being manufactured by the milling machine and no steel
material would be milled causing waste so as to preserve the
original nature of the steel.
[0023] Fourthly, a layer of polymeric resin material (20) is
provided for covering the thinner upper portion of the blade (10)
so as to greatly reduce the weight of the whole blade (10).
