Description
BRIEF DESCRIPTION
Snowshoes have conventionally been bulky items, usually made of a
hardwood frame and a thong lacing. While generally suitable for
their intended use for providing over snow mobility, they are not
always conveniently stored or carried. Thus, while cross-country
winter hikers, for example, may find it necessary or desirable to
carry snowshoes, they may also find it uncomfortable or difficult
to carry them because of their size. Also, with the increasing
popularity of snowmobiles, there has been an increase in the number
of stranded snowmobile riders who are forced to hike to safety or
help whenever their snowmobile breaks down. Snowshoes are
frequently needed by the stranded operators of broken-down
snowmobiles but they have seldom been available when needed in the
past, since there has not heretofore been available a snowshoe that
could be readily carried on the machine. Conventional snowshoes
have just been too large and bulky for convenient storage in the
small compartment space that may be available and are "in the way"
if merely attached to the exterior of the machine.
In U.S. Pat. No. 3,484,958, there is shown a foldable snowshoe that
folds to a compact condition, and this may be suitable for many
purposes. However, the use of folding joints is not always
satisfactory from a strength standpoint and it is not always
possible to have a taut mesh support unless some means are provided
to stretch the mesh.
It is a principal object of the present invention to provide a
breakdown or collapsible snowshoe that is light-in-weight, easily
assembled to provide a taut webbing support surface for use and
disassembled for compact transporting or storage.
Other objects are to provide such a collapsible snowshoe that is
unusually sturdy and yet that is made of readily available
materials and that can be economically constructed.
SUMMARY OF THE INVENTION
Principal features of the invention include a sectional tubular
frame, a net webbing arranged to be tautly stretched across the
frame and means arranged to releasably lock the sections of the
frame together for use while at the same time stretching the
webbing.
Other objects and features of the invention will become apparent
from the following detailed description and claims, together with
the accompanying drawing,
THE DRAWING
In the drawing:
FIG. 1 is a top plan view of one embodiment of an assembled
snowshoe of the invention;
FIG. 2, an exploded perspective view of the snowshoe of FIG. 1,
showing how it is disassembled, and how the foot harness is
affixed;
FIG. 3, a top plan view of another embodiment of the invention;
and
FIG. 4, an enlarged, fragmentary, perspective view showing an
anchor member portion of the snowshoe of FIG. 3.
DETAILED DESCRIPTION
Referring now to the drawing:
In the illustrated embodiment of the invention shown in FIGS. 1 and
2, the snowshoe, shown generally at 10, includes a tail section 11,
a center section 12 that has a foot harness 13 thereon, and a front
section 14. As illustrated, the front, central and rear sections
are of essentially the same length such that they can be
superimposed over one another for placement in a storage and
carrying bag, not shown. As so arranged, the snowshoe is a compact
unit that can be easily stored or carried.
The center section serves as the support area to carry the weight
of a wearer of the snowshoe and it must be strong enough to support
the weight placed thereon. This section includes a pair of spaced,
tubular siderails 15 and 16 that are connected intermediate their
lengths by rigid crossbars 17-19. The crossbars thus provide a
platform on which a user's foot may rest and to which the foot
harness 13 may be secured.
The foot harness includes a toe piece 20 that is adapted to be
secured to the forward crossbar 17 by rivets 21 and that folds back
over the toe of a user's shoe and ties using a string 22 laced
between the ends of the toe piece. Ankle straps 23 and 24 extend
rearwardly of the toe piece and are held separated by a heel piece
25 that slides on the ankle straps and that is adapted to fit
behind a user's foot. The ankle straps then come forward over the
top of the foot to be tied at the front thereof. While this harness
has proven very effective, it should be apparent that other harness
constructions can be used. The harness can be made of leather,
vinyls, reinforced neoprene or any other suitable material or
combination of materials.
Tubular coupling sections 26 and 29 extend from the rear of the
side rails 15 and 16, respectively, to provide telescoping coupling
means for the tail section 11 and similar tubular coupling sections
27 and 28 extend from the front of the siderails to provide means
for coupling the front section 14.
The tail section comprises a generally V-shaped tubular body member
30, the ends 30a and 30b of which are adapted to telescope into the
coupling sections 26 and 29. The coupling sections are bent to be
in alignment and receive the ends 30a and 30b.
The ends of member 30 are weaved through the sides of a net mesh or
webbing 31 that is shaped to stretch tautly across the member.
An anchor member 32 has its center portion 32a weaved through the
mesh 31 and has its end 32b and 32c bent to form hooks. The hooks
are somewhat resilient and fit over rear crossbar 19 of center
section 12, thereby holding the tail section and center section
securely together and tautly stretching the mesh 31.
Front section 14 has a generally U-shaped frame member 38, turned
up adjacent the web of the U, onto which is weaved a net mesh 35.
The mesh is stretched tightly between the legs of the U-shaped
member and another anchor member 36 has its center portion 36a
weaved through the mesh and its ends 36b and 36c bent to form hooks
that will engage the front crossbar 17 of the center section 12
when the front section and the center section are coupled together.
The engagement of the hooks with the front crossbar insures taut
stretching of the mesh 35.
To assemble the snowshoe of the embodiment of FIGS. 1 and 2, it is
only necessary to couple the tail and front sections 10 and 11 to
the center section 12. This is done by telescoping the ends 30a and
30b of body member 30 of the tail section into coupling sections 26
and 29, respectively; sliding the mesh 31 along the body member 30
and onto the coupling sections and siderails 15 and 16 of the
center section before hooking the ends of anchor member 32 over
rear crossbar 19. The ends of the U-shaped frame member 38 of the
front section are inserted into coupling sections 27 and 28, the
mesh 35 is pulled along the U-shaped frame member and the ends of
anchor member 36 are hooked over front crossbar 17.
To disassemble the snowshoe, it is only necessary to release the
anchor members and pull the front and tail sections from the center
section.
In FIGS. 3 and 4, there is shown a slightly modified embodiment of
the invention. In this embodiment, the tail center and front
sections 11, 12 and 14 of the snowshoe 10' are the same as
previously described, except for the manner in which the mesh is
affixed.
As best seen in FIG. 3, the ends of body member 30 of the tail
section are woven through a mesh 40, in the same manner as the mesh
31, previously described, but the mesh 40 is not adapted to move
onto the center section. Instead, a guide rod 42 is woven through
the mesh and rings 43 are provided at each end of the guide rod and
around the ends of member 30. The rings thus serve as guides as the
mesh is stretched, all as will be hereafter disclosed in more
detail.
Another mesh 44 is woven onto the siderails 15 and 16 of the center
section, passes beneath the rear crossbar 19 and is anchored to the
center crossbar 18 by an anchor 44' that is woven through the mesh
and that has its ends looped around the center crossbar. A guide
rod 45 is then woven through the opposite end of the mesh 44 and
rings 46 on the ends of the guide rod 45 extend around siderails 15
and 16 to slide thereon as the mesh 44 is stretched taut.
An adjustable strap 47 is passed around guide rod 45 and a hook 48,
carried thereby is adapted to engage the guide rod 42, when the
tail section and the center section are coupled together. The strap
46 is then drawn up tight to hold the sections together and the
mesh taut.
Still another guide rod 49 is woven through the mesh 50, that is
woven onto the U-shaped member 38, and rings 51 on the ends of the
rod 49 extend around the legs of member 38 and slide thereon.
A pair of spaced-apart, adjustable straps 52 and 53 are then passed
around the front crossbar and the hooks 54 and 55 carried by the
straps are adapted to engage the rod 48, when the front section 14
and center section 12 are coupled. When the hooks 54 and 55 have
been so engaged, the straps 52 and 53 are shortened in conventional
manner, to hold the sections together and the mesh 50 taut.
The foot harness of the embodiment of FIG. 3 includes an
adjustable, laced toe piece 57, riveted or otherwise fixed to the
front crossbar 17, and an adjustable heel strap 56, extending
rearwardly of the toe piece and having a buckle thereon whereby the
heel strap can be adjusted.
The snowshoe 10' can be disassembled by releasing the tension on
the straps 47, 52 and 53, releasing the hooks 48, 54 and 55 from
the guide rods 42 and 49, and by pulling ends 30a and 30b of the
tail section and the ends of U-shaped member 34 from the coupling
sections 25 and 26 and 27 and 28, respectively.
To assemble the snowshoe 10', a reverse procedure is followed.
While the snowshoe has been here shown and described as being made
up of three sections, it should be apparent that more or fewer such
sections could be used and that the desired size of the compacted
package will determine the size of the shoe and the number of
sections utilized. The arrangement shown has proven very
satisfactory for most uses however.
Although a preferred form of my invention has been herein
disclosed, it is to be understood that variations are possible and
are anticipated as coming within the scope of the following
claims.
