This invention relates to a snow-shoe consisting of a frame,
a sùpport surface arranged withln the frame and a clamping-
means for a shoe. - -
In order to make possible walking in snow it is previouslyknown to use snow-shoes. These have a relatively big support
surface to distribute the carrier t S weight and to prevent in
this way sinking in snow.
Known snow-shoes are often clumsy and require a special gait,
which is quite different ~rom a natural one. Rach snow-shoe
must bave a sur~iciently big support surface to distribute
the carrier~s whole weight, as the latter only rests on one
snow-shoe in walking. Often known snow-shoes prevent a natural
motion of the root in walking as the snow-shoe consists of
a rigid frame with an intermediate support sur~ace.
This invention provides a snow-shoe allowing an almost natural
gait at the same time as it will be possible to carry out work~;
with the snow-shoe clamped to the shoe, e.g. in a~crouched

position. By the present invention a snow-shoe is obtained,
which is simple, light, simple to manufacture and permits a
natural gait. According to the present invention this is
achieved by the snow-shoe obtaining the characteristic
features defined in the claims.
In accordance with one aspect, the invention relates
to a snow-shoe comprising a snow-shoe frame having a support
surface adopted to suppoxt said frame on a snow surface and
fastening means for fastening the snow-shoe to a shoe at a
position between the opposite ends of the frame, said frame
comprising front and rear portions having mutually adjacent
ends positioned below said means and which are interconnected
by elastic means for holding said ends against separation and
resiliently biased so as to normally hold said portions in
alignment with each other and elastically permitting said
portions to angularly deflect relative to each other so as to
substantially conform to bending of a shoe fixed to the snow-
shoe by said fastening means.
The elastic means may comprise rod-shaped elastic
bodies inserted and fixed in recesses in the mutually adjacent
ends of the front and rear portions of the frame.
The invention will be described in connection with an
illustrative example shown, wherein
Fig. 1 is a perspective view of a snow-shoe according
to the invention with a clamped shoe in a horizontal (not
articulated) position and wherein Fig. 2 is a perspective view
of the articulation of the snow-shoe.
The snow-shoe consists of a rear frame portion 1 and a
front fram~ portion 2, whose front part 2A is upwardly directed
3~ to some extent. Articulated elements 3 are disposed between the
front and the rear frame portion and are rigidly connected with

these. A support surface 4 is arranged at the frame portions
and consists perferably of a flexible material to which snow
adheres or sticks with difficulty. A clamping means 5 of a
shoe 6 is arranged on the upper side of the snow-shoe and can
consist of known lace means and clamping means of footwear.
Anti-skid means 7 r 8 are preferably arranged at the
frame portion.

As the articulation Or the snow-shoe is arranged ln connection
~with or on the same level as the articulation of the foot
immediately in front of the arch of the foot, a substantially
natural gait is possible. The articulation does not influence
injuriously the supporting capacity of the snow-shoe, either,
as the articulation, the posltion shown in Fig. 2, is only
`ukilized when a relativeiy small portion of the total body
weight rests on the angularly bent snow~shoe in walking. By
providing the snow-shoe with a relatively large longitudinal
extension a natural gait is also made possible, and therefore
reduced stresses will arise on thighs and sinews than is the
case with existing snow-shoes, which require a gait with the
legs wide apart. The articulation of the snow-shoe also
simplifies works when standing on the knees, e.g. in timber-
cutting, and does not prevent by its design, either, that work
is carried oUt with e.g. a power saw. The risk has then been
eliminated that the snow-shoe is damaged as its rear frame
portion has beèn given a longer extension in comparison with
the front one, which does not bring any impaired supporting
capacity.
The invention is not restricted to the illustrative example
shown, but modifications can be made within the scope of the
following patent claims.
