LIGHTED CHILD'S SNOWSHOE

PRIORITY CLAIM

This application claims priority to U.S. Patent Application No. 13/647,226, filed October 8, 2012, which is hereby fully incorporated herein by reference.

FIELD OF THE INVENTION

The invention relates generally to snowshoes. More particularly, the invention relates to snowshoes especially designed to be worn by young children.

BACKGROUND OF THE INVENTION It is well known that young children enjoy participating in adult activities with their parents and other family members to the extent that they are capable to appropriately participate. One outdoor activity that is appealing to young children is that of snowshoeing. Because of young children's light weight and their less developed physical skills, snowshoes for very young children are made differently from snowshoes for adults or older children. In particular, the snowshoes can be smaller because of the lower weight of the children and, quite often, they are made in such a way to provide additional entertainment value to the children. Snowshoes that are made in a form to resemble animal tracks are known and are produced by the owners of the present patent application.

During the winter, days are shorter and more of the hours when one might engage in outdoor recreation with children are during darkness. It is also well known that some children have a certain degree of fear of darkness but are less fearful in the presence of some sort artificial illumination.

However, presently available children's snowshoes that are molded from plastic leave room for improvement. SUMMARY OF THE INVENTION

A lighted child's snowshoe, according to an example embodiment of the invention, generally includes a deck, a toe panel, a lighting module and a snowshoe binding. The deck may be shaped to generally resemble an animal track or foot. The lighting module includes at least one electrically illuminated light source such as an LED.

The deck according to an example embodiment of the invention generally includes a toe portion and a heel portion, each having a top and a bottom. When viewed from above, the lighted child's snowshoe generally includes footbed and a paw portion. The footbed is centrally located and has a generally oval shape, somewhat wider at the front of the snowshoe than at the rear of the snowshoe. The footbed presents binding mount holes and heel grips thereon.

The paw portion extends generally outward from the footbed to some degree in all directions and presents an extended heel, side extensions and forward extending toes. Extending forwardly, outwardly from the toes are claws and claw reinforcements.

According to an example embodiment, claws include a first claw, a second claw, a third claw and a fourth claw. Each claw presents a light emitting diode, (LED) pocket. Claw reinforcements extend outwardly on each side of each claw and extend back to each respective toe. The paw portion also presents toe ovals including a first toe oval, a second toe oval, a third toe oval and a fourth toe oval.

When viewed from the bottom, the deck generally presents a toe portion and a heel portion.

The bottom of the toe portion generally presents a light module enclosure, a longitudinal rib, a transverse rib and a surrounding toe perimeter wall.

When viewed from the bottom, the heel portion generally presents the footbed wall and the heel perimeter wall. The footbed wall further includes footbed wall pegs extending downwardly therefrom. The heel perimeter wall generally presents heel perimeter wall pegs extending downwardly therefrom. The toe panel is a generally flat structure that is securable to the toe portion of the bottom side of the snowshoe deck. The toe panel, when placed together with the toe portion of the bottom of the main deck, bounds an enclosure. The toe panel generally includes a plate presenting toe grips including first toe grip, second toe grip, third toe grip and a fourth toe grip. The toe grips are presented on an outer side of the plate. The inner side of the plate presents LED supports including a first LED support, a second LED support, a third LED support and a fourth LED support. The inner surface of the toe panel also presents engagement members. The present invention also includes a lighting module including a battery, an impact activated switch or pressure activated switch, LEDs and leads. The LED's according to an example embodiment of the invention includes four LEDs, for example, including a first red LED, a blue LED, a green LED and a second red LED. According to the present example embodiment of the invention, the lighting module also includes long leads, short leads and continuity leads. Long leads in this example embodiment extend to the first and second red LED's while the short leads extend to blue and green LEDs. Continuity leads are of unequal lengths and have a small portion of stripped wire at the end and are present to prevent continuity of the lighting module until it is installed in the snowshoe to prevent depletion of the battery prior to sale. The continuity leads are coupled and insulated during final assembly.

The binding of the snowshoe according to the invention, is a generally conventional binding having a toe pocket, instep strap and a heel strap. The binding may also include a flex joint built therein and two screws for mounting.

Leads 186 as depicted, generally include two short leads 194, two long leads 196 and continuity leads 198. LEDs 188 are sized to be received into light emitting diode pockets 100. According to an example embodiment of the invention, LEDs 188 include two red LEDs 188, one blue LED 188 and one green LED 188. In the depicted embodiment, red LEDs 188 are coupled to long leads 196. Blue LEDs 188 and green LEDs 188 are coupled to short leads 194. Continuity leads 198 are of unequal length and include a short stripped area 200 near the ends thereof.

Referring to Fig. 16, binding 38 is generally conventional in nature and can be any binding presently known to those of ordinary skill in the art or any binding to become known in the future.

In operation, prior to sale and use, child's lighted snowshoe 30 is assembled by inserting lighting module 36 into deck 32 and securing toe panel 34 to deck 32. Toe panel 34 is aligned with toe portion 116. Prior to securing toe panel 34 to deck 32, lighting module 36 is inserted so that battery box 184 is positioned snuggly inside light module enclosure 22 with leads 186 extending outwardly through the gap between short front walls 132. LEDs 188 are inserted into light emitting diode pockets 100. LEDs 188 at the end of long leads 196 are inserted into first LED pocket and fourth LED pocket. LEDs 188 at the end of short leads 194 are inserted into second LED pocket 138 and third LED pocket 140. Stripped areas 200 of continuity leads 198 are electrically joined and may be sealed in an insulator if desired. Accordingly, switch 192, when activated, electrically couples battery 190 to LEDs 188 thus, causing illumination of LEDs 188. Thereafter, toe panel 34 is aligned with toe portion 1 16, so that alignment pegs 134 are received into alignment peg receivers 164. Leads 186 are arranged to pass through wire passages 168 and LED supports 166. Toe panel towers 162 are received within and adjacent to toe perimeter wall 126. Toe panel 134 may then be secured to deck 32 by, for example, a screw or screws or ultrasonic welding. Generally, for smaller volume manufacturing production, a screw is more appropriate. For larger volume production, ultrasonic welding may be utilized.

Snowshoe binding 38 is secured to deck 32 at binding mounting holes 58 generally by fasteners such as bolts and nuts.

In use, child's lighted snowshoe 30 is secured to the footwear of the child by the application of snowshoe binding 38 to the child's footwear. When the child walks or runs in child's lighted snowshoe 30, switch 192 is actuated by pressure or impact thus completing the circuit between battery 190 and LEDs 188 illuminating LEDs 188. Accordingly, child's lighted snowshoe 30 provides comforting illumination of the child as well as a certain degree of entertainment. Further, the presence of lighted LEDs 188 permits a parent or guardian to keep visual contact with the child during low illumination conditions. Further, because of the shape of child's lighted snowshoe which resembles an animal track, a child may be entertained by the fact that the tracks left behind in the snow look unusual and provide an opportunity for creative play with the tracks.

Heel grips 60 engage to a heel of the child's footwear to inhibit slippage of the heel relative to footbed 44 when the child's weight is on the heel. Footbed wall pegs 148, heel perimeter pegs 152 and toe grips 170 act as crampons to inhibit slippage of child's lighted snowshoe 30 relative of surfaces snowshoed on while being safe for young children in that the lack sharp edges. Footbed wall 144 and heel perimeter wall 146 sink into and engage snow and other formable materials to inhibit slippage of child's lighted snowshoe 30 relative to snow and the other formable materials.

While child's lighted snowshoe 30 has been described with reference to a snowshoe deck 32 resembles an animal track, it should be understood that should not be considered limiting. The shape of deck 32 may take other forms.

The present invention may be embodied in other specific forms without departing from the spirit of the essential attributes thereof; therefore, the illustrated embodiments should be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
