Description
2185~2 '_ TITLE OF THE INVENTION
Snowshoe.
FIELD OF THE INVENTION
The present invention pertains to an improved snowshoe.
More particularly, the present invention pertains to a snowshoe wherein the boot-supporting portion has a novel construction.
BACKGROUND OF THE INVENTION
There exists a wide variety of snowshoes, many of which employ wooden frames, others employing metal frames. Similarly, the webbing used in many snowshoes consists of a network of wooden strands of rawhide or, in some cases, of synthetic polymeric material. Examples of such snowshoes may be found described in: US Patent 2,699,613 issued January 18,1955 to Peterson; US Patent 4,271,609 issued June 9,1981 to Merrifield; Canadian Patent no. 993,468 issued July 20, 1976 to Prater; and Canadian Patent no.1,074,356 issued March 25,1980 to Gros-Louis.
Some snowshoes have deckings which are molded entirely of a relatively rigid plastics material. Examples of such snowshoes may be found described in: US Patent no. 4,045,889 issued September 6,1977 to Woolworth; US Patent no. 3,638,333 issued February 1,1972 to Sprandel;
US Patent no.3,299,541 issued January 24,1967 to Snyder; and US Patent no. 5,014,450 issued May 14, 1991 to McGrath. Most of the snowshoes constructed of a solid piece of rigid material become extremely heavy whenever packed snow or ice snow fills the various openings formed in the snowshoe to provide lightness.

US Patent no.3,299,541 issued January 24,1967 to Snyder; and US Patent no. 5,014,450 issued May 14, 1991 to McGrath. Most of the snowshoes constructed of a solid piece of rigid material become extremely heavy whenever packed snow or ice snow fills the various openings formed in the snowshoe to provide lightness.
2 5 It has been found also that molded plastic snowshoes in which the openings are filled with ice or snow are very slippery during use. Also, -whenever a part of a plastic snowshoe is damaged or broken, the entire snowshoe needs to be replaced. Concerning manufacturing, a mold is required for each type of snowshoe, which is a costly operation.

DESCRIPTION OF PREFERRED EMBODIEMENTS
Referring to figures 1 and 2, there is shown a foot covered with a boot or shoe 10 mounted in a harness 12, in a pivoted position relative to a snowshoe 14. The harness includes a pair of straps 15 and 16. The snowshoe 14 has a structural frame consisting of a peripheral frame 18 including two longitudinal side portions 20 and 22. The construction of this 20 structural frame is conventional and will not be described in detail; it can be said that it is pfeferably made of wood, but a metal frame could also be used.
The structural frame also includes two longitudinally-spaced cross-members 24 and 26 that divide the snowshoe in three sections, i.e. a front section which is slightly upturned, an intermediate section and a rear section.
The front section displays a hole-bearing decking 28 while the rear section displays a hole-bearing decking 32, both of which may consist 218585~
-of a resin-impregnated fabric or a laminate structure of leather and plastic:
it may also be a conventional webbed decking. In the embodiment illustrated in the drawings, an arrangement of plastic filament ties 34 and metallic eyelets 36 is used to secure the deckings 28 and 32 to the 5 peripheral frame and cross-members of the snowshoe.
The present invention pertains to the mounting of a plate 40 in the intermediate section of the snowshoe. This plate is formed of plastics material which may be a blend of polyethylene and polypropylene. It comprises a main rectangular area 42 from the front part of which projects o a pair of transversely spaced extensions 44 and 46. This plate includes a series of holes 47 along its periphery, i.e. in the rectangular area as well as in the two front extensions 44 and 46. A plurality of ties 48 secures the plate to the longitudinal side portions 20 and 22 of the frame as well as to the cross-members 24 and 26.
As can be seen in figures 3 and 4, the peripheral holes 47 each have a thicker annular reinforcement 50 on the top side to protect the peripheral plate in the areas where the ties exert a pulling force on the plate.
The front part of the plate comprises a series of openings 52, 54, 56 and 58 to permit the passage of straps 15 therethrough. Each 2 o opening has a reinforcement border area 52a, 54a, 56a and 58a on its under side, again to protect the plate against the stress exerted by the straps.
The front edge 59 of the plate is also subject to great stress.
Hence, there is provided a series of reinforcing ribs 60, 62, 64, 66, 68, 70 and 72 on the under side that extend rearwardly from the front edge. The stress exerted in this area is due to the weight of the user as well as the pivotal movements exerted by the boot during walking.
218~8~2 -In order to provide traction to the snowshoe, a series of cleats or spikes 74 are randomly disposed on and integral with the bottom face of the plate. One form of a cleat is illustrated and consists of a conical downward projection having an X shape when seen in top view. Also s providing traction is a transverse rib 75 located rearwardly of the front edge 59.
To provide friction to the heel of the boot, a series of small conical protuberances 76 are disposed on the top face of the plate.
The plate is made of a plastics material that has a certain 10 flexibility so that it may slightly deform under impact but return to its original shape thereafter.
Although the invention has been described above with respect to one specific form, it will be evident to a person skilled in the art that it may be refined and modified in various ways. It is therefore wished to be lS understood that the present invention should not be limited in interpretation, except by the terms of the following claims.

DESCRIPTION OF PREFERRED EMBODIEMENTS
Referring to figures 1 and 2, there is shown a foot covered with a boot or shoe 10 mounted in a harness 12, in a pivoted position relative to a snowshoe 14. The harness includes a pair of straps 15 and 16. The snowshoe 14 has a structural frame consisting of a peripheral frame 18 including two longitudinal side portions 20 and 22. The construction of this 20 structural frame is conventional and will not be described in detail; it can be said that it is pfeferably made of wood, but a metal frame could also be used.
The structural frame also includes two longitudinally-spaced cross-members 24 and 26 that divide the snowshoe in three sections, i.e. a front section which is slightly upturned, an intermediate section and a rear section.
The front section displays a hole-bearing decking 28 while the rear section displays a hole-bearing decking 32, both of which may consist 218585~
-of a resin-impregnated fabric or a laminate structure of leather and plastic:
it may also be a conventional webbed decking. In the embodiment illustrated in the drawings, an arrangement of plastic filament ties 34 and metallic eyelets 36 is used to secure the deckings 28 and 32 to the 5 peripheral frame and cross-members of the snowshoe.
The present invention pertains to the mounting of a plate 40 in the intermediate section of the snowshoe. This plate is formed of plastics material which may be a blend of polyethylene and polypropylene. It comprises a main rectangular area 42 from the front part of which projects o a pair of transversely spaced extensions 44 and 46. This plate includes a series of holes 47 along its periphery, i.e. in the rectangular area as well as in the two front extensions 44 and 46. A plurality of ties 48 secures the plate to the longitudinal side portions 20 and 22 of the frame as well as to the cross-members 24 and 26.
As can be seen in figures 3 and 4, the peripheral holes 47 each have a thicker annular reinforcement 50 on the top side to protect the peripheral plate in the areas where the ties exert a pulling force on the plate.
The front part of the plate comprises a series of openings 52, 54, 56 and 58 to permit the passage of straps 15 therethrough. Each 2 o opening has a reinforcement border area 52a, 54a, 56a and 58a on its under side, again to protect the plate against the stress exerted by the straps.
The front edge 59 of the plate is also subject to great stress.
Hence, there is provided a series of reinforcing ribs 60, 62, 64, 66, 68, 70 and 72 on the under side that extend rearwardly from the front edge. The stress exerted in this area is due to the weight of the user as well as the pivotal movements exerted by the boot during walking.
218~8~2 -In order to provide traction to the snowshoe, a series of cleats or spikes 74 are randomly disposed on and integral with the bottom face of the plate. One form of a cleat is illustrated and consists of a conical downward projection having an X shape when seen in top view. Also s providing traction is a transverse rib 75 located rearwardly of the front edge 59.
To provide friction to the heel of the boot, a series of small conical protuberances 76 are disposed on the top face of the plate.
The plate is made of a plastics material that has a certain 10 flexibility so that it may slightly deform under impact but return to its original shape thereafter.
Although the invention has been described above with respect to one specific form, it will be evident to a person skilled in the art that it may be refined and modified in various ways. It is therefore wished to be lS understood that the present invention should not be limited in interpretation, except by the terms of the following claims.
