Claims
Having thus described the invention, what I claim as new and desire
to secure by Letters Patent of the United States is:
1. A skate shoe which may be alternately fitted with either two or
four roller skate wheels or with an ice skate blade comprising
A shoe, a sole plate fastened to the underside of the shoe which is
formed as an open channel member together with a set of attachable
roller skate wheels and an attachable ice blade assembly that may
be interchangeably fastened to the channel member,
Said channel member formed with a flat plate section of the general
width of the shoe that is mounted adjacent the underside of the
shoe with a flange section integrally joined to each of the opposed
lateral sides of the flat plate section, said flange sections each
bent at an acute angle to the said flat plate section, with each
said flange section bent at its free end to form a support wall
section that lies in a plane perpendicular to the plane of the flat
plate section, said support wall sections being spaced apart by a
relatively uniform distance and fitted with mounting holes through
which the axles of skate wheels or bolts fastening the attachable
ice blade assembly may be mounted,
said flange sections joined together by a support bar spaced from
the flat plate section, oriented with the bar axis generally
parallel to the plane of the said flat plate section, which support
bar serves to maintain the flange sections and attached support
walls in a fixed spaced relation to each other.
2. The combination as recited in claim 1 in which a block fastened
to an ice skate blade is fastened between the walls of the channel
member.
3. The combination as recited in claim 1 in which two roller skate
wheels each rotatably mounted on an individual axle are each
fastened by their axles between the walls of the channel
member.
4. The combination as recited in claim 1 in which four roller skate
wheels, each pair of which are rotatably fastened to an individual
axle are mounted by their axles to the channel member so that each
wheel is located externally of the channel member, together with a
spacer mounted on each axle located between the walls of the
channel member.
Description
SUMMARY OF THE INVENTION:
My invention relates to a skate shoe which can alternately serve as
ice skate, a two-wheel roller skate or a four-wheel roller skate.
The frame of the skate shoe accepts an ice skate blade adapter or
an adapter mechanism which forms either a four or two wheel roller
skate.
BRIEF DESCRIPTION OF THE DRAWING:
The objects and features of the invention may be understood with
reference to the following detailed description of an illustrative
embodiment of the invention, taken together with the accompanying
drawings in which:
FIG. 1 illustrates a perspective view of the invention employed as
a two wheel roller skate;
FIG. 2 illustrates a front view of the invention in the form of a
two-wheel skate;
FIG. 3 illustrates a side view of the invention in the form of a
two-wheel skate;
FIG. 4 illustrates a front view of the invention in the form of a
four-wheel skate; and
FIG. 5 illustrates a front view of the ice blade adapter.
DESCRIPTION OF THE PREFERRED EMBODIMENT:
Turning now descriptively to the drawings, in which similar
reference characters denote similar elements throughout the several
views, FIGS. 1-3 show the skate 10 adapted to serve as a two-wheel
roller skate. A skate shoe 11 is fastened to a sole plate 13
integrally fitted with a center channel flange member 14. Flange
member 14 is of the general configuration of an inverted U-section
with the opposing walls 15 joined together by reinforcement strip
30, and the free ends 16 of the flange member 14 lying in parallel
planes.
Two axles 18 in the form of bolts fasten the two wheels 17 of the
skate between channel walls 16 through aligned holes in the bracket
14.
As shown in FIG. 4, the skate 10 may be readily fitted with four
skate wheels 17, with each pair of skate wheels 17 mounted on a
bolt axle 25 fitted with a spacer 20 which rides between channel
walls 16 and two spacers 23, each of which is located between a
skate wheel 17 and a channel wall 16.
Alternately all wheels 17 may be removed and an ice blade adapter
27 bolted between walls 16 of channel member 14 as shown in FIG. 5.
Adapter 27 is fitted with lateral holes 29 which align with the
attachment holes of channel member 14 and is in the shape of a
block 28 of rectangular cross-section to which a projecting ice
skate blade 31 is permanently fastened.
Since obvious changes may be made in the specific embodiment of the
invention described herein, such modifications being within the
spirit and scope of the invention claimed, it is indicated that all
matter contained herein is intended as illustrative and not as
limiting in scope.
