Abstract
ABSTRACT OF THE DISCLOSURE
A pair of floats and cross members are normally carried upon or in a house trailer or the towing vehicle. When it is desired to erect the floating assembly, for example, for a suitable boat launching site, a cross member is provided which spans the rear of the floats and two longitudinal members extend from the rear cross member, to the ground or supporting surface between and adjacent the front ends of the floats. The floats preferably should be located so that approximately two-thirds of their length is in the water with the front ends of the floats on the ground. The trailer is then backed up between the floats with the rear bumper of the trailer sliding up the ramps formed by the longitudinally extending members. When in position, the front of the trailer is disconnected from the car or truck and is elevated by the conventional jacking member, to a substantially level position whereupon the two longitudinal members are removed and placed between the floats and under the frame of the trailer, transversely, thus supporting the trailer between the floats with the underside of the trailer substantially level with the upper sides of the floats. Front and rear decking is then engaged across the floats of the front and rear of the trailer and an outboard motor may be used to give propulsion to the floating assembly which is then slid fully clear of the launching site into the water.

Description
~o9o~9 ~ACKGROUND OF THE INVENTION
This invention relates to new and useful improvements in floating assemblies for house trailers and the like.
S While amphibious vehicles have been known, nevertheless it is not feasible to adapt a conventional house trailer or the like, to a vehicle which can be pulled along the highway, or alternatively, can be launched and used as a boat or the like ma~ly because of the 8' width restrictions on the highways.
Also it i8 extremely difficult to completely seal the underside of a trailer and to provide sufficient flotation in the conventional construction. Further-more, it is difficult to supply a source of power to such a vehicle without having an inboard engine assembly or the equivalent. -SUMMARY OF THE INVENTION
The present invention over comes these di~advantages by providing a flotation assembly which can be carried either within or upon the house trailer or within or upon the vehicle towing same.
It can then readily be assembled on a supporting surface such as a boat launching ramp, beach, or dock whereupon the trailer can be engaged within the flotation assembly by the towing vehicle and can be supported by the flotation assembly readily and easily.
One aspect of the invention consists of a method of mounting a house trailer and the like upon a pontoon assembly which includes a pair of spaced and parallel pontoons, a rear transverse ..
lO90~g member extending between said pontoons at least two longitudinally extending members pivotally secured by one end thereof to said rear transverse member and extending forwardly and downwardly between said pontoons, said method comprising the steps of backing the trailer between said pontoons at the front end thereof, engaging the rear bumper of said trailer with said longitudinally extending members whereby said longitudinally extending members act as ramps to elevate the rear end of said trailer as it is backed between said pontoons, then elevating the front of said trailer removing the longitudinally extended members and using them as transverse members across said pontoons, then lowering the front of the trailer onto said transverse members and detachably clamping said trailer to said pontoon assembly.
Another aspect of the invention consists o a floating assembly for house trailers and the like which are detachably connectable to a towing vehicle and include a transverse rear bumper and a forwardly extending front hitch assembly for detachable connection to said towing vehicle; said floating assembly including a pair of pontoon components, means detachably secured to adjacent the rear ends of said pontoon components in a spaced and parallel relationship when assembled, longitudinally extending ramp means, detachably pivoted by one end thereof to said means spanning said pontoon components and extending forwardly between said pontoon components when in a trailer ramp-ing position, and movable from a trailer ramping lQ~O~9 pOSition when said pontoon components are upon a solid supporting surface, and a trailer supporting position and vice-versa, said longitudinally extending ramp members being movable to a transverse position across said pontoons and constituting means detachably secured between said pontoon components towards the f ront ends thereof and spanning said pontoon components, and means to detachably secure said ramp means to said last mentioned means, by the other ends of said ramp means, when said ramp means are in the trailer supporting position.
Another aspect of the invention consists of a fLotation assembly as hereinbefore defined, which can be decked in for and aft of the trailer to provide ~-~
a complete deck to this pontoon assembly and which furthermore can utilize a conventional outboard motor on the rear side thereof, for propulsion purposes.
A yet further aspect of the invention consists of an assembly which is easily assembled and disassemblea and carried either by the trailer or by the towing vehicle.
Another aspect of the invention consists of utilizing conventional house trailer or the like upon a flotation assembly so that it may be launched 2S upon a body of water whereupon the house trailer can act as living and sleeping quarters due to the provision of the services normally available to the occupants of a house trailer.
A further aspect of the invention consists 3G of a device which is simple in construction, economical in manufactureand otherwise well suited to the purpose lOgO~;~9 for which it is designed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement ana construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:-DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
. _ In detail, the floating or flotation assembly 11 consists of a pair of pontoons, each collectively designated 19 and preferably manufactured with a plurality of compartments 20 from glass fibre or the like and then skinned with a glass fibre outer shell 21 as shown, for example, in Figure 8.
The individual flotation compartments 21 may, if desired, be filed with a synthetic plastic foam 22 for additional flotation purposes or to prevent the ingreæs of water in the event that the outer skin i8 penetrated inadvertently.
In the present embodiment, each of the float components 19 is provided with a substantially planar -upper surface 23, a substantially vertical inner and outer side wall 24 and 24' respectively and a lower keel portion 25. If desired, a trimaran configuration may be given to the underside of the pontoon components.
A plurality of transversely extending apertures 26 are formed through the upper portion 22 of the pontoon components and are lined with sleeves 27 of glass fibre material or the like, for strengthening purposes.
In the present embodiment, a rear aperture 27A is provided, a front aperture 27B and a central aperture 27C.
Means are provided adjacent the rear of the pontoon components to maintain same in substantially ~; spaced and parallel relatlonship when assembled, said means taking the form of a rear frame member 28 which, in this embodiment, takes the form of an I-beam. How-ever, other configurations can be utilized.
10~0~i59 This rear transverse member is provided with angle member stops 29 transversely situated inboard of the ends 30 thereof and upon the upper and lower flanges 31 and 32 respectively, and the .
portions of the I-beams between these stops 29 and the outer ends 30, slidably engage through t~e rear apertures 27A in the pontoon components 19, thus maintaining at least the rear ends of the pontoon components in spaced and parallel relationship when ~;
assembled.
Means are provided to detachably secure the transversely extending frame member 28, in the desired position and in this embodiment, a small plate or nut 33 is secured to each end of the vertical web 34 of the member 28 and is provided with a screw threaded aperture 35 as clearly shown in Figure 7.
When inserted through the sleeve 27A, this plate 33 is situated substantially flush with the outer end of the sleeve 27A as shown in Figure 8, whereupon a plate 36 is engaged by screw threaded bolt 37 which in turn screw threadably engages the screw threaded aperture 35 in plate 33 thus clamping the assembly together at each end of the transverse frame member 28.
Means are provided to ramp the trailer into position between the pontoon assemblies 19, said means taking the form of a ramp assembly collectively designated 38.
In this embodiment, the ramp assembly includes two spaced and parallel I-beams 39 which are detachably pivotally secured to the front side of the rear 109~)~59 transverse frame member 28 and extend forwardly between the pontoon components when in the position shown in Figure 4.
One method of pivotally connecting the ramp S members to the rear transverse frame member 28, is shown in Figure 7 although it will be appreciated that any conventional pivotal connection can be used as desired.
A pair of tubes 40 are welded or otherwise secured to the front portion of the lower flange 32 of the member 28 and a central tube member 41 extends from the rear end 42 of the ramp member 39 and engages between the tube members 40 whereupon the pivot pin in the form of a nut and bolt assembly 43 may engage through the tubes 40 and 41 and pivotally connect the ramp members 39 to the transverse frame member 28 as described.
This pivotal connection of the ramp members 39 enables the ramp members to extend forwardly and downwardly between the pontoons and rest upon - the solid supporting surface 44 when the device is - being assembled. This portion is defined as the "trailer ramping positionn.
~owever, when in the trailer supporting ~5 position shown in Figure 5, these ramp members 39 are removed from the front transverse frame member and are slidably engaged through sleeves 27B and 27C in the pontoon components and secured in position by means of plate 36 and bolts 37 as hereinbefore described. Once these transverse frame members are in position, they may support the trailer as shown in Figure 5.
~O~ 5$~
Before describing the remainder of the structure it is believed desirable to explain the function of the invention to this point.
When it is desired to mount the trailer 10 upon the floating or flotation assembly 11, the two pontoons 19 and the rear transverse frame member 28 are assembled as hereinbefore described and the longitudinally extendinq ramp members 39 are pivotally conn~ted by the rear ends thereof to this transverse rear frame member 28 so that they extend forwardly and downwardly between the pontoons in a position substantially as indicated in Figure 4. The pontoons are then launched rearwardly until approximately two-thirds of the length thereof is in the water.
The house trailer 10 is then backed up by the towing vehicle (not illustrated) with the rear end of the trailer 10 entering between the front ends l9A of the pontoons. This causes the transverse rear bumper 12 together with guide plates 12A, to engage the ramp members 39 so that as the trailer is backed between the pontoon components, the rear of the trailer is elevated by the ramping action of the members 39 upon the rear bumper 12. Theguide plates 12A are welded to and depend downwardly from the front side of the bumper and engage outer surfaces of the ramp members 19 thus guiding the trailer up the ramp.
Thetrailer is backed to the position shown in Figures 1, 4 and 5 so that the rear bumper is directly over member 28 whereupon the jack assembly 14 is engaged upon blocks 18 by rotation of handle 15 (or electrically if such a unit is provided). As soon as _g_ lU9~5~
the weight ofthe front of the trailer is taken , by the jacking assembly 14, the towing vehicle is disconnected and removed whereupon the jacking assembly is utilized to raise the trailer to the substantially horizontal position illustrated in Figure 4.
When the trailer has been positioned so that the rear bumper is directly over the rear transverse member 28 it is stopped by two bumper I0 guide plates 12A welded transversely to the front bottom edge of the trailer transverse bumper. These plates act as guides on the longitudinal members 39 as the trailer is backed up the ramp. When the trailer is against the stops the front end is elevated by the conventional jacking assembly 14. The longitudinal members 39 are removed by removing nut and bolt assembly 43. The longitudinal members now become tranqverse members and are engaged through the sleeves 27B and 27C of the ponto~ns and below the frame of the camper. The jacking assembly 14 is then reversed to elevate the stem 17 from the blocks 18 and to lower the trailer frame upon the transverse members 39.
~he trailer is then cla.mpe~ to the forward transverse member 39 and the rear transverse member 28 by NJ--bolt 48. These transverse members 39 and 28 are secured in the desired position by plates 36 and bolt 37.
It will be noted that the lower side 47 of the trailer is substantially level with the upper surface 22 of the pontoon components 19.
It is then desirable to clamp the trailer in position upon the frame members and in this connect-ion, reference should be made to Figure 11 in which a 109(~i59 "J" bolt 48 is used. This "J" bolt 48 is provided with a short leg 49 and an elongated screw threaded leg 50. The short leg engages around the lower flange 39A of the longitudinal frame member 39 and the S elongated screw threaded leg engages through an aperture 51 formed through the longitudinally extending frame member 52 of the trailer just inboard of the transverse bumper 12 which is attached to the rear ends of the frame members. A nut 54 then is engaged upon the leg 50 and clamps the "J" bolt in position thus holding the trailer firmly to the flotation or floating assembly.
A similar "J" bolt is used on the other side corner of the rear of the trailer and a similar lS assembly may be used adjacent the front of the trailer between the hitch 13 and the transverse front frame member 39.
Once clamped into position, the front and rear decking may be engaged upon the pontoon components and in this regard, reference should be made to s Figures 9 and 10 of the drawings.
A substantially rectangular deck panel 55 is provided with a transverse, substantially rectangular cross sectioned member 56 which is secured under the rear o the panel 55. The deck panel 55 is preferably made from plywood, but of course other materials can be used.
The cross beam S~ is provided with ends which extend beyond the sides 57 of the deck panel and these side edges 57 of the deck panel rest upon the upper surfaces of the pontoons as illustrated in Figure 9.
10~
~olts 58 or similar fastening means, extend throuqh the cross beam 56 and into screw threaded bolt receiving receptacles 59 are provided within the ends of the upper surfaces of the pontoon components 19.
The front edge 60 of the deck panel 55 preferably engages under the rear bumper 12 so that no gap is left at this point.
The front deck panel 61 is also a rectangular panel spanning between the under surfaces of the pontoon components 19 and also having a cross beam 62 similar to cross beam 56 hereinbefore described.
It is also attached to the upper surfaces of the pontoon components adjacent the front ends thereof, by means of bolts 63 in a manner similar to that hereinbefore described. This front deck component also maintains the front ends of the pontoons in the spaced and parallel relationship desired.
The rear edge 64 of the front deck panel 61 terminates adjacent the front of the trailer hitch component 13 and fill in panels 65 may be secured to the front edge 64 by straps 66 or equivalent means and also these fill in panels rest upon the upper surface of the pontoons 19.
The rear beam 56 reinforced by the attachment of the panel 55 thereto, may be used to support a conventional outboard motor shown schematically in Figure 1 by reference character 66 thus providing propulsion to the assembly once it is launched.
The front and rear deck panels 55 and 61 together with the relatively wide upper surfaces 22 of the pontoons provide adequate walking space around lO9V~;59 the trailer which of course can be used in the conventional manner once the assembly has been launched on the beach or dock upon which it has been assembled, and it will also be observed that the S underside of the trailer is kept clear of the water with only perhaps the underside of the lower portion of the wheels becoming wet thus -preventing any undesirable effects of water upon the trailer.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims :~
without departing from such spirit and scope, it is intended that all matter contained in the :
accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

When inserted through the sleeve 27A, this plate 33 is situated substantially flush with the outer end of the sleeve 27A as shown in Figure 8, whereupon a plate 36 is engaged by screw threaded bolt 37 which in turn screw threadably engages the screw threaded aperture 35 in plate 33 thus clamping the assembly together at each end of the transverse frame member 28.
Means are provided to ramp the trailer into position between the pontoon assemblies 19, said means taking the form of a ramp assembly collectively designated 38.
In this embodiment, the ramp assembly includes two spaced and parallel I-beams 39 which are detachably pivotally secured to the front side of the rear 109~)~59 transverse frame member 28 and extend forwardly between the pontoon components when in the position shown in Figure 4.
One method of pivotally connecting the ramp S members to the rear transverse frame member 28, is shown in Figure 7 although it will be appreciated that any conventional pivotal connection can be used as desired.
A pair of tubes 40 are welded or otherwise secured to the front portion of the lower flange 32 of the member 28 and a central tube member 41 extends from the rear end 42 of the ramp member 39 and engages between the tube members 40 whereupon the pivot pin in the form of a nut and bolt assembly 43 may engage through the tubes 40 and 41 and pivotally connect the ramp members 39 to the transverse frame member 28 as described.
This pivotal connection of the ramp members 39 enables the ramp members to extend forwardly and downwardly between the pontoons and rest upon - the solid supporting surface 44 when the device is - being assembled. This portion is defined as the "trailer ramping positionn.
~owever, when in the trailer supporting ~5 position shown in Figure 5, these ramp members 39 are removed from the front transverse frame member and are slidably engaged through sleeves 27B and 27C in the pontoon components and secured in position by means of plate 36 and bolts 37 as hereinbefore described. Once these transverse frame members are in position, they may support the trailer as shown in Figure 5.
~O~ 5$~
Before describing the remainder of the structure it is believed desirable to explain the function of the invention to this point.
When it is desired to mount the trailer 10 upon the floating or flotation assembly 11, the two pontoons 19 and the rear transverse frame member 28 are assembled as hereinbefore described and the longitudinally extendinq ramp members 39 are pivotally conn~ted by the rear ends thereof to this transverse rear frame member 28 so that they extend forwardly and downwardly between the pontoons in a position substantially as indicated in Figure 4. The pontoons are then launched rearwardly until approximately two-thirds of the length thereof is in the water.
The house trailer 10 is then backed up by the towing vehicle (not illustrated) with the rear end of the trailer 10 entering between the front ends l9A of the pontoons. This causes the transverse rear bumper 12 together with guide plates 12A, to engage the ramp members 39 so that as the trailer is backed between the pontoon components, the rear of the trailer is elevated by the ramping action of the members 39 upon the rear bumper 12. Theguide plates 12A are welded to and depend downwardly from the front side of the bumper and engage outer surfaces of the ramp members 19 thus guiding the trailer up the ramp.
Thetrailer is backed to the position shown in Figures 1, 4 and 5 so that the rear bumper is directly over member 28 whereupon the jack assembly 14 is engaged upon blocks 18 by rotation of handle 15 (or electrically if such a unit is provided). As soon as _g_ lU9~5~
the weight ofthe front of the trailer is taken , by the jacking assembly 14, the towing vehicle is disconnected and removed whereupon the jacking assembly is utilized to raise the trailer to the substantially horizontal position illustrated in Figure 4.
When the trailer has been positioned so that the rear bumper is directly over the rear transverse member 28 it is stopped by two bumper I0 guide plates 12A welded transversely to the front bottom edge of the trailer transverse bumper. These plates act as guides on the longitudinal members 39 as the trailer is backed up the ramp. When the trailer is against the stops the front end is elevated by the conventional jacking assembly 14. The longitudinal members 39 are removed by removing nut and bolt assembly 43. The longitudinal members now become tranqverse members and are engaged through the sleeves 27B and 27C of the ponto~ns and below the frame of the camper. The jacking assembly 14 is then reversed to elevate the stem 17 from the blocks 18 and to lower the trailer frame upon the transverse members 39.
~he trailer is then cla.mpe~ to the forward transverse member 39 and the rear transverse member 28 by NJ--bolt 48. These transverse members 39 and 28 are secured in the desired position by plates 36 and bolt 37.
It will be noted that the lower side 47 of the trailer is substantially level with the upper surface 22 of the pontoon components 19.
It is then desirable to clamp the trailer in position upon the frame members and in this connect-ion, reference should be made to Figure 11 in which a 109(~i59 "J" bolt 48 is used. This "J" bolt 48 is provided with a short leg 49 and an elongated screw threaded leg 50. The short leg engages around the lower flange 39A of the longitudinal frame member 39 and the S elongated screw threaded leg engages through an aperture 51 formed through the longitudinally extending frame member 52 of the trailer just inboard of the transverse bumper 12 which is attached to the rear ends of the frame members. A nut 54 then is engaged upon the leg 50 and clamps the "J" bolt in position thus holding the trailer firmly to the flotation or floating assembly.
A similar "J" bolt is used on the other side corner of the rear of the trailer and a similar lS assembly may be used adjacent the front of the trailer between the hitch 13 and the transverse front frame member 39.
Once clamped into position, the front and rear decking may be engaged upon the pontoon components and in this regard, reference should be made to s Figures 9 and 10 of the drawings.
A substantially rectangular deck panel 55 is provided with a transverse, substantially rectangular cross sectioned member 56 which is secured under the rear o the panel 55. The deck panel 55 is preferably made from plywood, but of course other materials can be used.
The cross beam S~ is provided with ends which extend beyond the sides 57 of the deck panel and these side edges 57 of the deck panel rest upon the upper surfaces of the pontoons as illustrated in Figure 9.
10~
~olts 58 or similar fastening means, extend throuqh the cross beam 56 and into screw threaded bolt receiving receptacles 59 are provided within the ends of the upper surfaces of the pontoon components 19.
The front edge 60 of the deck panel 55 preferably engages under the rear bumper 12 so that no gap is left at this point.
The front deck panel 61 is also a rectangular panel spanning between the under surfaces of the pontoon components 19 and also having a cross beam 62 similar to cross beam 56 hereinbefore described.
It is also attached to the upper surfaces of the pontoon components adjacent the front ends thereof, by means of bolts 63 in a manner similar to that hereinbefore described. This front deck component also maintains the front ends of the pontoons in the spaced and parallel relationship desired.
The rear edge 64 of the front deck panel 61 terminates adjacent the front of the trailer hitch component 13 and fill in panels 65 may be secured to the front edge 64 by straps 66 or equivalent means and also these fill in panels rest upon the upper surface of the pontoons 19.
The rear beam 56 reinforced by the attachment of the panel 55 thereto, may be used to support a conventional outboard motor shown schematically in Figure 1 by reference character 66 thus providing propulsion to the assembly once it is launched.
The front and rear deck panels 55 and 61 together with the relatively wide upper surfaces 22 of the pontoons provide adequate walking space around lO9V~;59 the trailer which of course can be used in the conventional manner once the assembly has been launched on the beach or dock upon which it has been assembled, and it will also be observed that the S underside of the trailer is kept clear of the water with only perhaps the underside of the lower portion of the wheels becoming wet thus -preventing any undesirable effects of water upon the trailer.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims :~
without departing from such spirit and scope, it is intended that all matter contained in the :
accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
