L6] INVENTOR. j LOYD a. L/VA UDA/S T BY EMV/J d/ l qi United States Patent 3,242,898 DEVICE FOR WALKING 0N WATER Loyd Joseph Livaudais, 1325 North Parkway, Memphis, Tenn. Filed Aug. 5, 1965, Ser. No. 482,019 12 Claims. (Cl. 115-26) This is a continuation-in-part of my prior application Serial Number 75,222 filed June 15, 1964. The invention relates to a device for use in walking on water. In particular, the present invention relates to that type of device which includes a pair of side-by-side floating members respectively attached to the feet of the user.

Heretofore, there have been various attempts to provide devices for walking on water, but in general these prior devices have lacked two important factors, namely control and minimum friction. Many of the previous devices had large and unwieldy floats or pontoons, and complicated and heavy mechanisms for connecting the floats or pontoons, which made such devices difficult to walk with and control the direction of movement. Also, many of these previous devices had unstable characteristics and caused undue strain on the persons ankles and feet due to the twisting action of the devices. It is believed that the lack of widespread commercial success of previous devices is primarily due to the above-mentioned factors. The present invention is directed towards overcoming the above-mentioned and other disadvantages in prior devices by providing a water walker which operates on the pendulum truss principle.

Thus, one of the objects of the present invention is to provide a device for walking on water that comprises a rigid frame, a split type boat (a pair of side-by-side closely spaced narrow boats, as opposed to previous floats and pontoons), and pendulum truss means movably interconnecting said rigid frame respectively with said narrow boats.

A further object is to provide such a device that is highly stable and requires a minimum of effort for its operation so that any person, old or young, can safely and easily operate this device for various purposes, such as fishing and other water sports. A

A further object is to provide such a device that is provided with improved means for directional control.

A further object is to provide such a device including means for selectively changing the direction of movement to forward or rearward directions.

A further object is to provide a modified form of such a device that can be used on either ice or water.

A further object is generally to improve the design and construction of devices for walking on water, ice or the like.

The means by which the foregoing and other objects of the present invention are accomplished and the manner of their accomplishment will be readily understood from the following specification upon reference to the accompanying drawings, in which:

FIG. 1 is a perspective view of the device of the present invention shown with the user in a standing position.

Referring now to the drawings in which the various parts are indicated by numerals, the device 11 of the present invention comprises, in general, a rigid and generally fore and aft extending frame 13, a pair of sideby-side closely spaced

narrow boats

15, 17 disposed in parallel relationship with each other and with frame 13, a pair of forward pendulum truss assemblies 19, 21, and a pair of rearward pendulum truss assemblies 23, 25.

Referring now in more detail to the various parts, the

boats

15, 17 are, in effect, a split-type boat which together preferably have an overall width comparable to a full width boat and thus together have the same stable safety characteristics as any skiff or dory of comparable size.

Boats

15, 17 are substantially identical, and the following description of boat 15 should suffice for both:

Boat 15 includes a substantially flat bottom 27, a substantially vertically extending outer side 29, a substantially vertically extending inner side 31, a bow 33, a stern 35, and substantially U-shaped members 37 fixedly mounted on the interior of the boat adjacent the bow and stem thereof to add rigidity to the boat.

Sides

29, 31 respectively depend below bottom 27 for portions as at 39, 41, which can serve as runners if the device is to be used on ice or the like, and to which are pivotally mounted a plurality of paddles 43 for pivot about transverse axes as by means of the transverse rods 45 to which the paddles are attached and which respectively extend through apertures in the depending portions 39, 41. Paddles 43 are spaced longitudinally along the bottom of boat 15. A plurality of stops 47, which are preferably constructed of rubber or the like, are fixedly mounted on depending portions 39, 41 forwardly of paddles 43 to limit clockwise pivot of the paddles, as viewed in FIG. 4, to a depending forward position, as shown in this figure.

It will be understood that the paddles 43 are free topivot counterclockwise from said forward position to rearwardly inclined positions, and the purpose of which will be better understood in the description of the operation of the device 11 to follow later in the specification.

Forward truss assembly 19 and rearward truss assembly 23 are associated with boat 15 and movably interconnect frame 13 respectively adjacent the forward and rearward ends thereof to boat 15. Likewise, forward truss assembly 21 and rearward truss assembly 25 are associated with boat 17 and movably interconnect frame 13 with boat 17. The truss assemblies 19, 21, 23 and 25 are substantially identical, and the following description of truss 9 assembly 23 and its connection with frame 13 and boat 15 should suffice for all:

A bearing 49 is mounted on frame 13 adjacent the rearward end thereof and pivotally receives the inturned upper end portion 51 of a depending arm 53 so that the arm is pivotable about an axis extending transversely of frame 13 and device 11. In other words, arm 53 is pivotable in a vertical plane extending fore and aft of the device 11 parallel to frame 13. Means is provided for pivotally attaching arm 53 adjacent the lower end thereof to boat 15, and this means is preferably similar to that construction usually found connecting a bicycle pedal and its associated lever. Thus, a pedal-like member 55 is pivotally mounted on an out-turned portion 57 adjacent the lower end of arm 53, and pedal-like member 55 is attached to bottom 27 as by means of the fastening assemblies 59 so that the pivot axis of the above-described connection of arm 53 with boat 15 extends transverse relative to boat 15 and device 11 in parallel relationship to the pivot axis of the arm with frame 13. Rearward truss assembly 23 preferably additionally comprises a brace rod 61 fixedly attached to arm 53 intermediate the upper and lower ends thereof as by the lug 63. Brace rod 61 extends outwardly and downwardly from arm 53 in an imaginary plane through the upper and lower pivot axes of arm 53 heretofore described. The lower end of brace rod 61 is out-turned as at portion 65 and pivotally attached to bottom 27 in transverse alignment and spaced outwardly from out-turned portion 57. The pivotal attachment of out-turned portion 65 is by any suitable means, such as the bearing 67 attached to bottom 27 as by means of fastening assemblies 69. It will be understood that the pivot axes of the lower end of arm 53 and the lower end of brace rod 61 coincide.

The

bearings

71, 73 and '75 respectively of

truss assembliesv

19, 21 and 25, which correspond to hearing 49 of truss assembly 23, are preferably arranged in the following manner: Bearing '73 is located just rearwardly of bearing 71 and mounted transversely on frame 13. Bearings 4-9 and 715 are mounted on frame 13- adja-cent the rearward end thereof with bearing 49 being just forward of bearing 75. Another arrangementor modified arrangement of the bearings is shown in FIG. 6, wherein it will be seen bearing 71 is located. just rearward-1y of bearing 73, and bearing 75 is located just forward of bearing 49.

From the foregoing it will be understood that

boats

15, 17 can swing in fore and aft movements relative to frame 13 and that the boats are restricted to this straight fore and aft movement in parallel relationship with each other and with the frame. Also, it should be noted that the only connection with the

boats

15, 17 of frame 13' is through the

truss assemblies

19, 21, 23 and 25. Frame 13, which is located between the

boats

15, 17, is elongatedfore and aft and is preferably narrow in its dimension which is transverse of device 11. Frame 13 is preferably of tube-like construction and preferably includes an upper member 77 and a lower member 79 rigidly interconnected by the pieces 81 to provide a, very light open frame construction. The forward and rearward ends of frame 13' extend above the upper edges of the boats15, 17, and the frame is preferably depressed adjacent the midi-portion thereof, as best seen in FIG. 4.

A forward rudder-assembly 83 is provided adjacent; the forward part of frame 13,. and a rearward rudder assembly 85 is preferably provided adjacent the rearward end; of the frame. Forward. and

rearward rudder assemblies

83,, 85 are substantially identical, and the following descrip.-. tion of rearward rudder assembly 85 and its, connection with frame 13 should suffice for both:

Rearward rudder assembly 85 includes a verticalrudder post 87 pivotally mounted from frame 13 for pivot about a vertical axis as by means of an upper bushing 89 attached to frame 13 adjacent the rearward end thereof and a lower bushing 91 supported from the frame by means of a diagonal brace 93. A rudder 95 i m n ed on. the ower end of rudder post 87 for turning movement with the rudder post. Rudder is preferably pivotally mounted from the rudder post as by means of a pin 97 extending through aligned apertures in the bifurcated lower end of the rudder post and through the upper end of the rudder. Rudder 95 is limited in its downward pivoting movement to the position shown in FIG. 4 by contact of the upper portion of the rudder with the portion of the rudder post 87 between the bifurcated lower end thereof, but the rudder is free to pivot upwardly, or counterclockwise as viewed in FIG. 4; as when an object is bit under water, or when traveling on ice. or the like, the rudder can pivot up into a position between depending portions 39, 41.

A lever 99 is fixedly attached to rudder post 87 adjacent the upper end thereof and extends outwardly to either side thereof. A control rod 161 ispivotally attached at one end thereof to one end of lever 99, and the opposite end of the control rod is pivotally attached to the remote end of the corresponding lever 103 of forward rudder assembly 83, Anothercontrol rod 105 is pivotally mounted in the same manner to the other ends of levers 99, 1%. In other words, the control rods 1G1, 105 are crossed so that movement of lever 99 will cause a similar but op posite movement of the other lever 103, whereby the rudder 95 and the corresponding rudder 107 .of forward rudder assembly 8-3 will swing in opposite directions. The means for moving lever 99 preferably comprises a lever 109 pivotally mounted on frame 13 as at pivot point 111. Lever 109 has a handle 113 at one end thereof and is connected to a lever 114 fixedly mounted on rudder post 87 as by means of the link 115 respectively pivotally connected adjacent opposite ends to lever-s 169, 114.

A seat 117 is preferably mounted on the top of frame 13 adjacent the rearward end thereof so that the user A of the device 11 can sitdown if he so desires,

Feet attaching means such as

straps

119, 121 and heel. retainers 123, 125- are respectively attached to the

boats

15, 17 on the upper surfaces of bot-

toms

27, 127 for removably receiving the left and right feet of the user. A who takes a position straddling frame 13 with his left foot in boat 15 and his right foot in boat 17,, as best seen in FIG. 1. Then the user A causes the de vice 11 to move through the water by moving his legs back and forth in much the same manner as in walking, but, of course, his feet and

boats

15, 17 are not picked up but caused to slide back and forth on top of the water. It will be understood that, if desired, only one leg, instead of both legs, may be moved back and forth, in either of which cases the boats will be propelled forwardly. This propelling actionis illustrated in FIG. 3 wherein it will be seen that the right leg is moving boat 17 rearwardly, in which case the paddles 43; are depending downwardly and are urged against the stops 47 by the force of the water; and the boat 17 is caused to be pulled forwardly. The other leg, or left leg, is moving forwardly to pull boat 15 forwardly, in which case the paddles 43- pivot rearward-1y. Inother words, in this example shown in FIG. 3', the right leg is on a pulling stroke and the left leg is on a trailing or idling roke.- It will be understood that at all times the frame 13 floats free and moves upwardly and downwardly as the

truss assemblies

19, 21, 23 and 25 are moved back and forth. Thus, when the

truss assemblies

19, 21, 23. and 25 reach their mid-point, i.e., when they depend straight down fromthe frame 13, the frame will be at its highest point, and when the truss assemblies are at their extreme positions of, swing, the frame will be at its lowest point, Also, it will be understood that the action of frame 13 and the truss assemblies 19,. 21, 2'3- and 25 is similar to the movements of a person during walking, with the truss assemblies being equivalent to the persons legs and the frame being equivalent to the pelvis of the person. The pendulum established by the

truss assemblies

19, 21', 23' and 25 swinging from the,

frame 13 are of such a length that the mid-ordinant distance is very small, so that the device 11 requires a minimum amount of work to propel it. In other words, the only lifting work required is to lift the frame 13 the short upward distance as the truss assemblies travel towards the mid-point of their swing. In addition, since the

boats

15, 17 move back and forth in horizontal and parallel motions, a minimum amount of resistance to the water is encountered.

Referring now to the modified paddle 129 shown in FIG. 8, the paddle is provided with a plurality of depending points or spikes 131 along the bottom edge thereof, so that the points can dig into the ice and propel the boats forward, or the body portion 133 of the paddle 129 can serve to propel the device through the water in the manner heretofore described relative to the paddle 43.

Referring now to the modified stop arrangement shown in FIG. 7 for providing rearward as well as forward motion of the device 11, the remainder of the device, not shown, is the same as in the preferred embodiment. In FIG. 7 it will be understood that bottom 135 corresponds to bottom 27 of the preferred embodiment, and depending portion 137 corresponds to depending portion 39 of the preferred embodiment. The mechanism for only one boat is shown in FIG. 7, but it will be understood that both of the boats preferably have this mechanism. The paddles 139 are pivotally mounted as at pivot points 141 in the same manner as the pivotal mounting of paddles 43 in the preferred embodiment. However, the paddles 139 are preferably enlarged as at 143. For purposes of clarity, it should be noted that in FIG. 7 the bow of the boat represented is to the left, as viewed in this figure, and the stern of the boat is to the right. For each paddle 139 there is a forward stop 145 and a rearward stop 147. Means are provided for selectively moving the forward stops 145 into place forwardly of enlarged portions 143 and the rearward stops 147 into inoperative positions, as shown in solid lines in FIG. 7, to provide a forward movement of the boat, and to move the forward stops 145 into an inoperative position and the rearward stops into operative positions behind the enlarged portions 143, as shown in broken lines in this figure, to provide rearward movement of the boat. Forward stops 145 are respectively mounted on the ends of levers 149, and rearward stops 147 are respectively mounted on the ends of levers 151, with the levers being pivotally mounted as at pivot points 153 and with arms 155 rigidly attached to the

levers

149, 151. The upper ends of arms 155 are movably interconnected by means of a link 157 which is pivoted to the respective arms adjacent the upper ends thereof as at pivot points 159. From the foregoing it will be understood that when link 157 is moved forwardly, the arms 155 will be rotated counterclockwise and cause pivot of

levers

149, 151 to move the levers into the broken line position, and rearward movement of link 157 will carry the

levers

149, 151 into the solid line position. Also, it will be understood that, on the forward arm 155, it is only necessary to have lever 149 and, on the rearward arm, it is only necessary to have the lever 151; but for the intermediate arms 155, both

levers

149, 151 are provided, and they are joined together adjacent the inner ends thereof where they are attached to the arms.

Referring now to the second embodiment of the in vention, that is, the embodiment indicated by numeral 161 and illustrated in FIGS. 9 through 12, the second embodiment comprises, in general, a rigid and generally fore and aft extending frame 163, a pair of side-by-side

narrow boats

165, 167 disposed in parallel relationship with each other and with frame 163, a pair of forward

pendulum truss assemblies

169, 171 and a pair of rearward

pendulum truss assemblies

173, 175. Pair of

boats

165, 167 are similar to

boats

15, 17 of the first described 6 embodiment except that

boats

165, 167 preferably are pontoon like and have sealingly secured

top boards

177, 179 respectively.

Second embodiment 161 includes bridge structure rigidly interconnecting

boats

165, 167 and such structure includes forwardly and rearwardly

disposed cross members

181, 183 and a center member 185.

Cross members

181, 183 are fixedly secured respectively to the forward and rearward end portions of top boards of 177, 179 of

boats

165, 167 and rigidly join the boats in parallel and substantially rectangular configuration. Center member 185 is fixedly secured respectively to the under surfaces of

cross-members

181, 183 and is disposed medianally of

boats

165, 167. Center member 185 preferably is T-shaped in cross section and formed of two board like

members

187, 189. The oppositely disposed end portions respectively of member 187 are fixedly secured to the medianally disposed undersurfaces of

cross members

181, 183. The construction or relative arrangement of

boats

165, 167 and the bridge structure of the craft is such that the respective bottom surfaces 191, 193 of

boats

165, 167 are preferably co-planar with bottom edge surface 195 of cross member vertical member 189.

Frame 163 is rigidly supported from center member by a pair of

upstanding post members

197, 199. Flanged base portions 201, 293 of the respective post members are fixedly secured respectively to the forward and rearward portion of center member 185 and support the respective post members. 'Frame member 163 is fixedly supported from

post members

197, 199 with the upper end portions respectively of the post members fixedly secured respectively in

sockets

205, 207 of the frame member.

A pair of footboards 269, 211 are disposed respectively on opposite sides of center member 185. Forwardly disposed pair of

pendulum truss assemblies

169, 171 and rearwardly disposed pair of pendulum truss assemblies 173, interconnect respectively footboards 299, 211 with frame member 163. The respective truss assemblies are substantially identical and the following description of truss assembly 173 and its connection with frame 163 and footboard 2119 will also sufiice for

truss assemblies

169, 171 and 175:

A bearing 213 is mounted in frame 163 adjacent the rearward end portion thereof and pivotally receives the inturned upper end portion 215 of depending arm 217 so that the arm is pivotable about the axis extending transversely of the frame of device 161. Means is provided for pivotally attaching arm 217 adjacent the lower end thereof to footboard 209 and this means is preferably similar to the construction described in the first embodiment. Thus, a pedal-like member 219 is pivotally mounted on outturned portion 221 adjacent the lower end of arm 217 and member 219 is fixedly attached to the upper surface of footboard 209 by suitable fastener means.

Truss assemblies

169, 171, 173 and 175 thus respectively pendantly mount footboards 269, 211 from frame member 163 so that the footboards can be made to swing back and forth, and are restricted to parallel movement relative to each other.

A plurality of paddles 2 23, 225 are pivotally mounted respectively along the under surfaces of

footboards

209, 211. Transversely extending

rods

227, 229 respectively pivotally mount

paddles

223, 225 from the respective footboards. Each paddle is attached to a respective footboard in like manner, and the following description of the attachment of a paddle 223 to footboard 299 illustrated in FIG. 12 will suffice for all:

Footboard 299 is provided with a rectangular aperture 231 transversely medianally disposed in the footboard and extending therethrough, and a pair of oppositely disposed socket openings 233 extending coaxially and inwardly respectively from the opposite disposed edges of footboard 209. Paddle 223 includes a medianally disposed hinge portion having an aperture 235, a main body portion 237 and an upwardly disposed tab portion 239. Paddle 223 is pivotally secured with rod 227 extending through aperture 235 and with the oppositely disposed end portions of the rod being back-turned and secured respectively in socket Openings 233. Pivotally secured, as such, the forward movement of main body portion 237 or the clockwise rotation (as viewed in FIG. of paddle 223 is limited by tab part 239' abuttingly engaging the rearwardly disposed surface 241 of aperture 231. Tab portion 239 thus functions in a manner similar to stops 47 as described in the first embodiment and causes the

respective paddles

223, 225 to function in like manner as paddles 43.

Feet attaching straps

243, 245 and heel retaining

members

247, 249 are respectively fitted on footboards 2G9, 211 for re ceiving respectively the right and left foot of the user.

A seat 251 is mounted on frame member 163 intermediate the ends thereof and handle bars 253 are mounted on the frame member adjacent the forward end thereof.

In using embodiment 161, the user preferably sits on seat 251 with the main body support being thereon and while holding handle bars 253, he moves his feet back and forth to cause the footboards 299, 211 to swing in arcs and to propel the device through the water by the action of the

paddles

223, 225. It will be understood that the paddles during the rearward or power strokes will be in the depending position shown in solid lines in FIG. 10 and during the forward or return strokes will be in the broken line positions. In embodiment 161, the directional control of the device may be accomplished by varying the force or effort applied to one footboard relative to the other footboard. That is, should the user desire to direct the craft toward the right, he would apply or exert greater effort with his left leg and greater effort on footboard Conversely, should he desire to move toward the left he would apply a greater effort on footboard 211. However, if desired, steering mechanism, as for example, like that shown in embodiment 11, may be incorporated into embodiment 161.

A desirable feature of embodiment 161 resides in the fact that when this embodiment is in use, the

respective paddles

223, 225 are not completely submerged in the water. Referring to FIG. 10, it will be noted that the water surface (indicated S) is substantially at the midportion of each paddle and the water level is substantially below the undersurface of the respective footboard. Such a construction reduces considerably the resistance or the amount of drag of the craft as it moves through the water.

Although the invention has been described in some detail by way of illustration and example for purposes of clarity or understanding, it is to be understood that it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of this invention as hereinafter claimed.
