The present disclosure relates generally to a portable ice shelter with an expandable fishing area.
Ice fishing is a popular winter past time in northern climates. Ice fishing is the activity of catching fish through an opening in the ice on a frozen body of water such as a lake, river, or pond. Ice houses, also known as ice shanties in some locations, are small shelters that are used to protect an ice angler from the elements including wind and blowing snow.
Various portable ice shelter mounted on sleds are disclosed in U.S. Pat. Nos. 4,239,247, 6,397,870 and U.S. Patent Publication No. US2006/0238005. These portable ice shelters can be easily moved by the anglers and quickly set-up at different locations. For example, U.S. Pat. No. 6,397,870 discloses a portable ice fishing shelter with a central fishing hole formed in the hull. The central fishing hole provides a relatively small fishing area and limits the usable space within the hull.
U.S. Patent Publication No. US2006/0238005 discloses an ice fishing sled with a conventional canopy that extends outside the perimeter of the sled to surround the available fishing area. Once the canopy is deployed the fishing area is fixed.
The present portable ice shelter includes at least one frame member that can be expanded to increase the size of the fishing area available to the user. At least the bottom frame member can be modified to increase the width and surface area of the fishing area.
In one embodiment the portable ice shelter includes a base with a bottom wall and side walls that form an upper perimeter. At least one frame bracket is mounted to the base. A chair is located in the base comprising a user orientation directed toward a fishing area. A plurality of folding frame members is pivotally attached to the frame bracket. The folding frame members are moveable between a transport configuration and a deployed configuration configured to support a canopy covering. A bottom frame member is moveable between the transport configuration and a deployed configuration. The bottom frame member extends beyond the upper perimeter of the base in the deployed configuration to surround a first fishing area with a first width generally perpendicular to the user orientation. At least one joint on the bottom frame member is configured to modify the bottom frame member to a second fishing area with a second width at least 40% greater than the first width. The second fishing area is greater than the first fishing area. A canopy covering extends over the folding frame members and the bottom frame member to substantially surround the base and the first and second fishing areas.
The bottom frame member is optionally pivotally attached to the frame brackets. Articulating hinges preferably attach the bottom frame member to the frame brackets. In another embodiment, the bottom frame member is detached from the base in the deployed configuration.
The at least one joint can be selected from one or more of a hinge, a telescopic joint, an overlapping joint, a ball joint, or a separable joint. In one embodiment, the bottom frame member includes a pair of frame members pivotally attached to a pair of frame brackets, hinges attached to distal ends of the tubes, and a pair of L-shaped frame members with proximal ends attached to the hinges and a joint connecting distal ends. The hinges preferably restrict motion of the frame members relative to the L-shaped frame members to a single plane. At least one locking mechanism is provided to secure the bottom frame member relative to the frame brackets.
The second fishing area is preferably at least 20 percent greater than the first fishing area. In another embodiment, the second fishing area is at least 30 percent greater than the first fishing area.
A chair collapsible is releasably attached to the base. The chair is preferably completely below the upper perimeter when in the collapsed configuration. The chair includes attachment clips oriented at an upward angle relative to horizontal. The attachment clips are configured to engage and disengage with the base only when the chair is oriented at the same angle.
The present disclosure is also directed to a method of deploying a portable ice shelter. The method includes pivotally moving a plurality of folding frame members attached to a base by frame brackets between a transport configuration generally located along an upper perimeter of the base and a deployed configuration configured to support a canopy covering. A bottom frame member is located beyond the upper perimeter of the base in the deployed configuration to surround a first fishing area with a first width generally perpendicular to a user orientation. The bottom frame member is modified to an expanded configuration that surrounds a second fishing area with a second width at least 40% greater than the first width. A canopy covering is positioned over the folding frame members and the bottom frame member in the deployed configuration to substantially surround the base and the first and second fishing areas.
In the description which follows, like parts or elements are marked throughout the specification and drawings with the same reference numerals, respectively. The drawing figures are not necessarily to scale and certain features may be shown in somewhat generalized or schematic form in the interest of clarity and conciseness.
The base 58 is preferably a water tight hull that is designed to keep the occupant afloat in the event of a catastrophic ice failure. In one embodiment, the base 58 is a molded structure with a nominal wall thickness in a range of about 0.20 inches to about 0.10 inches.
The folding chair 54 is illustrated in a collapsed configuration 72. The folding chair 54 is preferably located in the recess 66 completely below the reinforced upper perimeter 64 when in the collapsed configuration 72. The remainder of the recess 66 can be used to store additional gear during transport. The folding chair 54 includes a user orientation 55 generally directed at fishing area 104.
The folding canopy assembly 56 includes a plurality of folding frame members 74A, 74B, 74C (“74”) pivotally attached to frame brackets 76. The frame brackets 76 are attached to the base 58 proximate rear edge 78. Although the frame members 74 are illustrated as generally rectangular, a variety of other shapes are possible (See e.g.,
As best illustrated in
The frame brackets 76 restrict movement of the folding frame members 74 to rotation around respective pivot axes 82 between transport configuration 52 (see
By contrast, bottom frame member 86 is coupled to the frame bracket 76 by articulating hinges 88 that provides two degrees of freedom. The articulating hinges 88 are preferably attached to outer surfaces of the plates 80B. The articulating hinges 88 rotate around pivot axes 90 that are generally parallel to pivot axes 82. Secondary pivot axes 92 permits tubes 94 to rotate outward in a plane containing the pivot axes 90. The tubes 94 are permitted to move in a plane that is generally perpendicular to the planes in which the vertical portions 74V of the frame members 74 move.

The bottom frame member 86 of the present disclosure, however, can be reconfigured from a compact configuration 123 (see
Opposite ends of the L-shaped frame members 108 are attached to distal ends 112 of the tubes 94 by hinges 114. The hinges 114 preferably restrict movement of the L-shaped frame members 108 relative to the tubes 94 to a single plane to prevent the frame member 86 from twisting or becoming unmanageable.
The frame members 74, 86 can be made from a variety of plastic materials or metals such as aluminum, aluminum alloys, titanium and titanium alloys, and other suitable materials known in the art. The frame members 74, 86 can have any suitable cross-sectional configuration to provide strength and minimal weight. For example, the poles can have a circular, square, diamond, or a hexagonal cross-section.
As illustrated in
The hinges 114 and secondary pivot axes 92 preferably restrict expansion of the bottom frame member 86 to a single plane, again to prevent twisting. In one embodiment, the width 119 increases from between about 30 inches to about 50 inches, or an increase of about 67%. The expanded fishing area 106 also has a width 120 that is at least 40% greater, and preferably at least 50% greater than the width 119 of the fishing area 104.
The tubes 94 rotate outward relative to the frame bracket 76 in the range of about 15 degrees to about 30 degrees. The resulting expanded fishing area 106 is preferably more than about 20 percent greater than the fishing area 104. In another embodiment, the fishing area 106 is more than about 25 percent, or more than about 30 percent greater than the fishing area 104.
It will be appreciated that it is possible to include a plurality of joints and hinges on the bottom frame member 86. The five-sided fishing area 106 could include six or more sides, and can be symmetrical or asymmetrical. The trade-off for adding more joints 110, 114 is the increased chance that the bottom frame member 86 will twist or become unmanageable. Another consideration is that the canopy covering 100 (see

In one embodiment, one or more joints/hinges 121′ are provided to permit the folding frame members 74′ to be configured in either a compressed configuration or an expanded configuration. In another embodiment, the frame members 74′ are fixed in the expanded configuration. Any of the joints disclosed herein can be used with the frame members 74′ of the present embodiment.
In one embodiment, the bottom frame member 86″ is pivotally attached to the frame brackets 76″. Once in the deployed configuration 84″ the bottom frame bracket 86″ is detached and permitted to rest on the ice as illustrated. In another embodiment, the bottom frame member 86″ is only attached to the canopy cover 100 and not to the frame brackets 76″. The canopy cover 100 supports the bottom frame member 86″ during deployment.
One or more joints/hinges 121″ are optionally provided to permit the bottom frame members 86″ to be configured in either a compressed configuration or an expanded configuration. In another embodiment, the bottom frame members 86″ is fixed in the expanded configuration. Any of the joints disclosed herein can be used with the bottom frame member 86″ of the present embodiment.

In operation, the canopy covering 100 is attached to the frame members 74, 86. As the user moves the bottom frame member 86 from the transport configuration 52 to the deployed configuration 84 the other frame members 74 are automatically deployed. Once the bottom frame member 86 is in a generally vertical position (see e.g.,
