Collapsible snow grooming device

Abstract

A collapsible snow groomer designed to be provided as a partial kit where the buyer purchases two runners separately. Along with the runners the kit comprises all materials necessary to assemble a snow groomer for use on personal snow trails. The collapsible snow grooming device of the present invention includes and comprises: a tubular front spreader, two L-angle cross blades, a square central joiner tube, four angle grooming blades and all required fasteners. All grooming hardware members are thus strategically attached to one edge of each runner and to each other at one edge, thereby allowing to flip the whole assembly over to drag it where grooming is not desired.

1 . A collapsible snow grooming device comprising:
 i. two side runners,   ii. a structural beam,   iii. a front tie bar,   iv. a central blade spreader,   v. a rear blade spreader,   vi. two gathering blades,   vii. two dispersing blades,   viii. a towing tongue, and   ix. an anti-jolt hitch.   
   
   
       2 . The collapsible snow grooming device of  claim 1  wherein the runners are reversible from top to bottom. 
   
   
       3 . The collapsible snow grooming device of  claim 1  wherein the structural beam is a tubular square form having predrilled perforations to ease alignment of mating components. 
   
   
       4 . The collapsible snow grooming device of  claim 1  wherein the front tie bar is located at mid-height of the runners so as to enable similar towing attitude when device is rotated on its back. 
   
   
       5 . The collapsible snow grooming device of  claim 1  wherein the central blade spreader has an “L” shaped cross-section and that the mouth of the “L” is directed downwardly and frontwardly. 
   
   
       6 . The collapsible snow grooming device of  claim 1  wherein the rear blade spreader has an “L” shaped cross-section and that the mouth of the “L” is directed downwardly and frontwardly. 
   
   
       7 . The collapsible snow grooming device of  claim 1  wherein the two gathering blades have an “L” shaped cross-section and that the mouth of the “L” is directed downwardly and frontwardly, and are disposed in a “V” formation where the mouth of the “V” faces forward. 
   
   
       8 . The collapsible snow grooming device of  claim 1  wherein the dispersion blades have an “L” shaped cross-section and that the mouth of the “L” is directed downwardly and frontwardly, and are disposed in a “V” formation where the mouth of the “V” faces rearward. 
   
   
       9 . The collapsible snow grooming device of  claim 1  wherein all hardware components can pack into a relatively small package so as to reduce shipping size thus cost. 
   
   
       10 . The collapsible snow grooming device of  claim 1  wherein the whole assembly may be rotated 180 degrees on a lengthwise axis so as to simply towing the device and disengage grooming members from the trail below. 
   
   
       11 . The collapsible snow grooming device of  claim 1  wherein the tongue is adapted with an anti-jolt hitch further comprising a joiner plate having two angular rearwardly extending flanged each having at least one perforation so as to accept one or more fasteners for the securement of both tongue members along with the tie bar, a central perforation traversing the joiner plate allowing the traverse of a shock bolt on which a resilient spring is adapted over the front and rear portions of said bolt at each side of said joiner plate, and the shock bolt is threadedly engages to a clevis where said clevis is retained onto a machine's hitch by means of a retainer pin. 
   
   
       12 . The collapsible snow grooming device of  claim 1  wherein said device, when towed over particular material, manages said material where the gathering blades cut down high points and amass same material toward the center region of the device, filling any voids in the material at the central region of the device, and the dispersion blades further cut down material and disperse same material toward the outer region of the device, filling any voids in the material at the outer region of the device. 
   
   
       13 . The collapsible snow grooming device of  claim 1  wherein the hardware components, excluding the runners, are provided to the user in kit form thereby substantially reducing the total cost to the user.
