This invention concerns transport of ice shanties. It is common for ice shanties to be towed out across the surface of frozen lakes to sites where fishing through ice is to take place using a snowmobile or ATV, as considerable distances can be involved on larger lakes. A convenient form of ice shanty involves a molded plastic base shaped as a small hull with an attached tent frame opened for shelter while fishing seated on the seat in the hull.
The hull may be hauled using a snowmobile or ATV as the towing vehicle, or may simply be manually pulled by the user using a pull rope. Snowmobiles and ATV's are quite costly and bulky to trailer.
Manual transport is slow and laborious especially disadvantageous when any great distances are involved. It is the object of the present invention to provide low cost, compact equipment for powered transport of an ice shanty across a snow or ice surface.
The above recited object as well as other objects which will be appreciated upon a reading of the following specification and claims are achieved by a simplified tracked propulsion device combined with a fishing shelter base the propulsion comprised of a frame mounted track drive and an engine mounted on the frame drivingly connected to the track drive as with a transmission belt to power the same.
In one embodiment, a pair of skis are mounted below a forward end of the frame, and the frame is large enough to accommodate an ice shanty base-hull placed thereon. The skis are pivotably moved by a handle bar type steering member to allow steering of the device.
In another embodiment, the base-hull is mounted to a tracked propulsion device by a pivotal connection allowing articulation between the propulsion device and base-hull by rotation of a connected steering member connected to the propulsion device to achieve a steering compatibility.
In one version of this embodiment the hull trails the propulsion device and is steered by a U-shaped steering member connected to the propulsion device frame and projecting back over the base-hull.
In another version, the base-hull is disposed ahead of the propulsion device and a tiller type steering member is used to pivot the propulsion device and steer the same.
In both embodiments, the user is seated in the base-hull when underway and holds the steering member projecting from the propulsion device and over the base-hull when seated therein in both versions of the second embodiment.
In the following detailed description, certain specific terminology will be employed for the sake of clarity and a particular embodiment described in accordance with the requirements of 35 USC 112, but it is to be understood that the same is not intended to be limiting and should not be so construed inasmuch as the invention is capable of taking many forms and variations within the scope of the appended claims.
Referring to the drawings, and particularly
An upwardly and rearwardly extending steering member 20 is mounted to the frame 12, preferably able to be telescoped to be collapsible as seen in
The steering member 20 is drivingly connected to both of a pair of arms 22 and pivot pins 23 via tie rods 24 pivotably connected with quick release connection to a swing plate 26 coupled to the steering member 20. This enables swinging of the skis 18 to provide a steering capability.
The engine 14 drives a belt 28 (could also be a chain) circulated around first sheave 30 fixed to a cross shaft 32. A smaller diameter sheave 34 is also fixed to the cross shaft around which a second belt 36 is circulated to achieve a reduction drive to a sheave 38 mounted on a track drive shaft 40 rotatable on a track mounting structure 12A affixed to the frame 12.
A pair of re-circulating drive tracks 42 are driven thereby around idler sprockets 44 at the rear of the frame 12 supported on hangers 46. The tracks 42 are conventional commercially available components which each have a series of spaced cleats 45 affixed along a flexible belt to effectively obtain traction on ice and snow. A single larger track could also be used instead.
The frame provides a support platform to the rear of the engine 14 and steering member 20 on which a fishing shelter base hull 50 can be placed as seen in
The shelter base-hull 50 is provided with a pivoting seat 54 mounted to be slidably adjustable side-to-side on a mounting bar 56 which bar 56 can be shifted forward when driving on guide bars 57 to position the seat 54 forward.
The user is seated on the seat 54 when transporting the shelter base-hull 50 out to a fishing site. The bows and covering are collapsed and stowed in the base-hull 50 at that time.
After arrival and flipping up and over of the bows 52-1-4 and stretching out the fabric cover 54, the user can be seated within the enclosure facing one side of the base-hull 50 to conveniently enable fishing through a hole in the ice on one side as shown in
The propulsion device 10A includes a shorter frame 12A including an upper platform 58 supporting a small gasoline engine 14A driving a belt 28A which drives a sheave 30A fixed on a track drive shaft 40A. The drive shaft 40A drives two track sprockets 60 affixed thereto which causes respective spaced apart tracks 42A to be re-circulated about idler sprockets 44A as in the above described embodiment.
The base-hull 50 is pivotably attached to the frame 12A by a pair of rods 62 each attached to one front corner of the base-hull 50 and converging to a quick release pivot connection 64 on the platform 58 at their other ends.
A U-shaped steering frame member 66 comprised of spaced apart tubes 68 connected at one end to each rear corner of the frame upper platform 58 and connected together at their upper end by a common cross tube 70.
Engine controls 72 such as a throttle may be mounted to the cross tube 70 for convenience. A user can operate the device 10A while seated in the seat 54 mounted to the cross bar 56.
A user seated in the base-hull 50 can pivot the propulsion device 10A using the steering frame 66 to thereby achieve steering. The pivot connection 64 allows articulation between the base-hull 50 and the propulsion device 10A.
