Powered Boots

Abstract

Electric Powered Boots are a new compact and rugged motorized multi-terrain micro-vehicle for individual powersports, mobility for ground troops, or anyone who has difficulty in walking or running. For use on snow, sand, asphalt, hard dirt, or mud, electric powered boots elevate the prior teachings of motorized surf boots of U.S. Pat. No. 5,643,029 to the next level of fit, form, and function, by adding novel features and components in an innovative packaging arrangement that provides increased safety, functionality, and ergonomics during use on land.

DETAILED DESCRIPTION OF THE DRAWINGS

[0020] In an embodiment of the invention that may be used in snow or sand, as shown in FIGS. 1-4 as reference numeral 200, and their sub-parts, the pair of boards employed are illustrated by the reference numeral 10, as being of predetermined length, width, thickness, and overall shape in accordance with the size and weight of the rider 15. The boards 10 are constructed of any suitable materials or combinations thereof.

[0021] The pair of boards 10 provide individual platforms, one for each leg of the rider 15 to stand on. On the tops of the boards 10 there other strategically placed components to aid the rider in controlling the pair of boards, including the boots, or foot braces 12, the Chassis to Connect Motorized Surf Boots of U.S. patent Ser. No. 17/237,960, referenced by numeral 70, and also the Retractable Handlebars for use on Motorized Surf Boots of U.S. patent Ser. No. 17/238,144 referenced by numeral 80. Also positioned on the top sides of each of the pair of boards are electronics compartments 100, in which are house electronics which operate electric motors 30 described later herein.

[0022] On the bottom side of the boards 10, are attached longitudinally placed bearing assemblies 40, which ride on a shaft 41, that is mounted to a shaft mounting block 42. The purpose of components 40-43 or other suitable components is for; while standing on the pair of boards, the rider will have the ability to impart a roll angle to the boards, by combining foot action within the foot braces 12 and leveraging the handlebars 80, rotate the boards off the horizontal to either side as desired. Additionally, by use of the chassis 70, the boards will remain at a fixed distance to each other and parallel, and share the same angle of rotation, so that when the powered boots 200 are being ridden, the rider will be able to lean or “carve” into turns.

[0023] The pair of longitudinal bearing components 40-42 and/or other suitable components in which to facilitate a roll angle imparted to the pair of boards is each also connected respectively to each of a pair of carriages 50. The pair of carriages 50 rides smoothly over the pair of track assemblies 20 by use of multiple shock absorbers 60, which are connected from the sides of the carriages 50, downwards to the side panels 28. Additionally, extending down on each side from the carriage 50 to the side panels 28 are linear motion bearings 62 to prevent forward or rearward shifting of the carriage 50 with respect to the track assembly 20 as the shock absorbers perform their function. Mounted to the top side of each carriage 50 are batteries 120 which primarily provide the energy to power the electric motors 30. The batteries 120 may also provide power to various other optional features that can be easily fitted onto the Powered Boots including lights, horns, music, mobile phones, among others. The pair of carriages 50 are constructed of any suitable materials or combination thereof.

[0024] The track assemblies 20 may consist of various configurations as is well known to those skilled in the art of assembling track systems. The track assemblies shown in FIGS. 1-4 are of the full track type. FIG. 4 shows an expanded view of one possible configuration for the track assembly where there is a bottom frame 25, where electric motors 30 are housed and attached by screws 32 or other suitable means. The electric motors 30 drive a belt 31, which turns a drive gear 33. Said drive gear 33 has internal splines in its bore, which mates with the drive shaft 29 which also has splines along its length. Also, with splines in their bore are drive wheels 21 which are positioned along the drive shaft 29, on either side of the drive gear 33. Once assembled through the drive wheels 21, drive gear 33, and thrust bearings 91, the drive shaft 29 is inserted through holes in each of the side panels 28, where, on the outside includes a welded-on bush 98, to add roller bearing 92, washer 93, and axle nut 94. Additionally shaft 39 can be inserted through a nose roller 38 and in like manner pass through thrust bearings 91 and side panels 28, and held in place by roller bearings 92, washer 93, and nut 94. In this case however, a loose bush 97 is employed, which when used in conjunction with a threaded block 96 which is welded to the side panels 28, and the tension adjustment bolt 95, which once threaded through block 96, will contact bush 97, thus will provide a tensioning mechanism after the continuous track 90 is fitted. Next, the top frame 26 can be assembled and attached to both the lower frame 25 and side panels 28 with the upper screws 27 or other suitable attachment scheme. Rollers 22 can be added to both the lower frame 25 and the upper frame 26. The rollers 22 will perform as additional guides for the track 90, especially towards the bottom, where the track 90 interfaces with the terrain. The number of rollers 22 employed, may vary, according to the many various sizes of powered boots that can manufactured according the teaching described herein. The final component to complete the track assembly 20 is to add the continuous track 90, which is typically made from a rugged rubber or woven material that is fitted around all the wheels 21 and rollers 22. The continuous track 90 will be seen to include a pattern of holes or other suitable features, that when the track is properly tensioned with the tensioning bolts 95, mate with the protrusions on the drive wheels 21, in order to keep the track 90 rotating at the same rate as the drive wheels 21 and prevent the track 90 from slipping. Additionally, there will be seen longitudinally along the center of the inside surface of the track 90, teeth that protrude inward, so that when the track 90 is installed and properly tensioned, prevents the track from shifting from side to side.

[0025] While the above discusses an assembly arrangement for a full continuous track, it should be readily appreciated that a half-track could be described just the same, whereby a set of skis may occupy the forward portion of the apparatus of the powered boots 200. Additionally, it should be also appreciated that the track assemblies 20 described herein may be configured to not include the continuous track 90, but only ride on the large drive wheels 21, where the drive wheels 21 may include a typical tire tread for use on asphalt or hard dirt.

[0026] In the many track 20 configurations possible, without deviating from the scope of the teaching herein, an alternative position for the electric motors 30 may be employed by nestling them inside of the drive wheels 21 as is possible with commonly known electric hub motors.

[0027] While there have been described what are considered to be a preferred configuration of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. For at least such reason, therefore, resort should be had to the claims appended hereto for a true understanding of the scope of the invention.
