Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to ice fishing houses and more
particularly to collapsible ice fishing houses which are portable
in nature.
2. Description of the Prior Art
The concept of providing a shelter to protect ice fishermen from
the elements during harsh winter conditions is not new. Such
shelters come in many shapes and sizes and in the form of rigid or
collapsible structures which may be considered relatively permanent
or portable. With particular reference to structures of the
collapsible type employing walls of either rigid or flexible
materials, problems have arisen in that hardware permitting such
structures to collapse is often overly complicated or unable to
stand the rigors of use. Also, such hardware on many occasions must
be completely detached when the structure is collapsed with the
result that parts thereof may be lost or misplaced. In addition,
such collapsible structures, when constructed to accommodate a
number of fishermen, have resulted in devices which generally
present weight problems, which are difficult to erect or collapse
and which are prohibitively expensive. Examples of known prior art
U. S. patents showing devices of the above character are listed
below.

SUMMARY OF THE INVENTION
With the advent of the snowmobile, which is particularly adapted to
move such structures to desired locations, the need for a
collapsible shelter that is light in weight, relatively compact in
size (when in a storage-transport position) and able to accommodate
a number of persons in its erect operative position has been
recognized. The present invention provides such a collapsible ice
fishing house having a floor structure including a center section
and a pair of wing sections foldable from a planar position to a
storage-transport position. The floor structure supports a frame
from which a flexible enclosure is suspended. The frame includes
front and rear arch members which are connected together by
horizontal frame members to lie in spaced parallel vertical planes,
and vertical stabilizer elements extending between each of the arch
members and the center section of the floor structure. The arches
and vertical stabilizer elements are provided with hinge joints to
permit the arch members to collapse within the spaced parallel
vertical planes, and the vertical stabilizer elements to collapse
in a plane perpendicular to and therebetween the spaced parallel
vertical planes when the floor structure is folded to the
storage-transport position. Angular brace members are movable from
a position to maintain the fishing house in an erect operative
position, to a position to maintain the house in a
storage-transport position. Skid runners are secured to the center
section and wing sections of the floor structure to support the
floor structure in both the planar position and the
storage-transport position.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring initially to FIGS. 1 and 2, a collapsible ice fishing
house constructed in accordance with the present invention is
indicated generally by the numeral 15. Ice fishing house 15
comprises a sectioned floor structure 16 including a center section
17 and a pair of wing sections 18 hingedly connected to center
section 17 by hinges 19. The hinges 19 provide for pivotal
movements of the wing sections 18 from a position wherein the floor
structure 16 is disposed in a generally horizontal planar position
(see FIGS. 1 and 2) to a storage-transport position wherein the
wing sections 18 are disposed in generally parallel planes
generally perpendicular to the center section 17 (see FIG. 3).
Frame means, indicated generally by the numeral 20, are supported
by the floor structure 16 in a manner to provide means for
suspending a flexible enclosure 21. Flexible enclosure 21 is a
generally rectangular tent-like structure with a hip roof and is
suspended within the confines of the frame means 20 by means of a
plurality of tie members 22. An L-shaped opening 23, equipped with
a conventional zipper closure member, is formed in one of the side
walls of the flexible enclosure 21 to permit egress from and
ingress into the enclosure 21. As required by law, in the case of
angling for fish, a transparent window 24 is provided to admit
light into the interior of the enclosure 21. In cases where
darkness is required or permitted within the enclosure 21, such as
during the spearing of fish, an opaque flap (not shown) may be
provided to cover the window 24. In addition to the tie members 22,
anchoring strips 25 may be utilized to secure the base of the
flexible enclosure 21 to the floor structure 16. Also, as is usual
in structures of this type, I have provided a plurality of spaced
openings 26 for fishing through the floor structure 16. Each of the
openings 26 is positioned adjacent a different corner of the floor
structure 16.
Frame means 20, now to be described in greater detail, includes
front and rear arch members 27, 28 each disposed adjacent
respective front and rear edges of the floor structure 16. Each of
the arch members 27, 28 comprises a plurality of arch portions
having upright or erect operative positions (see FIGS. 1 and 2) and
collapsed storage-transport positions (see FIGS. 3, 4 and 5). As
seen particularly in FIGS. 1 and 2, the plurality of arch portions
forming the front and rear arch members 27, 28 include upwardly
inclined rafter elements 29 and laterally spaced vertical support
elements 30 having opposite end portions which are joined to form
peak and haunch joints 31, 32 respectively. Horizontal frame
members 33 extend between and join the arch members 27, 28 at the
peak and haunch joints 31, 32 respectively, to support the arch
members in spaced generally parallel vertical planes lying inwardly
of respective front and rear edges of the floor structure 16.
A vertical stabilizer element 34, comprising a plurality of
stabilizer portions 35, extends between each arch member 27, 28 and
the center section 17 of the floor structure 16. The uppermost
stabilizer portion 35 is rigidly attached to and depends from the
peak 31 for a reason which will become apparent hereinafter.
Hinge means connecting the arch portions of front and rear arches
27, 28 and the stabilizer portions 35 of stabilizer elements 34, to
permit collapsing movements of each of the arch members 27, 28 in
its respective vertical plane and each of the stabilizer elements
34 in a plane perpendicular to and extending between the vertical
planes of the arch members 27, 28, include hinge members 36, 37,
38, and intermediate hinge members 39. As shown, hinge members 36
join rafter members 29 to form the peaks 31. Hinge members 37 join
rafter members 29 and vertical support elements 30 to form the
haunch joints 32. Hinge members 38 join the vertical supports 30
and vertical stabilizer element 35 to the floor structure 16. The
intermediate hinge members 39 join opposite end portions of the
rafter members 29, vertical support members 30 and lower vertical
stabilizer portions 35. For the purpose of providing a maximum
degree of stability to the hinge members 36-38 and the intermediate
hinge members 39 during all phases of collapsing movements of the
arch members 27, 28 and stabilizer elements 34, each of the hinge
members 36-38 and the intermediate hinge members 39 is formed to
include spaced guide plates 40 disposed on opposite sides of
respective rafter elements 29, vertical support elements 30 and
stabilizer elements 34. Each pair of guide plates 40 is rigidly
affixed to a common element while a pivot pin 41 carried by the
adjacent element is journaled in the pair of guide plates for
pivotal movements of the other element therebetween. Thus, as can
be seen from FIGS. 7, 8 the pairs of guide plates 40 may be shaped
to guide the other element through a given amount of travel of the
other element between the plates 40 from 0.degree. to 180.degree.
without damage to the pivot joint in spite of lateral forces
exerted thereon for various reasons.
In view of the multiple hinged connections of the various parts of
the frame means 20, it is necessary to provide means for
maintaining the arch members 27, 28 in their upright operative
positions as well as the floor structure 16 in its horizontal
planar position illustrated in FIGS. 1 and 2. For this purpose I
provided angularly disposed brace members 42, each of which extends
from one of the vertical support elements 30 to a respective wing
section 18 intermediate the arch members 27, 28, and angularly
disposed brace members 43 which each extend from a vertical support
element 30 to the center section 17. FIG. 9 illustrates a typical
connection of an end of the angularly disposed brace member 42, 43
to a respective element. In addition to the angular brace members
42, 43 I provide angular brace members 44 which extend between each
of the stabilizer elements 34 and its respective rafter element 29
to support the rafters 29 in the position shown in FIGS. 1 and 2.
FIG. 6 illustrates a typical ball hinge connection of the angular
brace members 44 to their respective elements. As can be seen from
the FIGS. 1 and 2, the particular placement of the angular braces
42-44 provides for a relatively rigid supporting frame means 20 and
floor structure 16 capable of supporting the flexible enclosure 21
in spite of adverse weather conditions, such as high winds or heavy
snowfall, which occur frequently during the winter months. As seen
particularly in FIG. 1 of the drawings, the vertical stabilizer
elements 34 each include a central hinge portion, having
intermediate hinge 39 thereon, disposed interiorly of the flexible
enclosure. This arrangement provides additional support to the
front and rear walls of the flexible enclosure 21 during windy
conditions as well as permitting collapsing movements of the
stabilizer elements 34 in their respective planes during collapsing
movements of the frame means 20, as will be described
hereinafter.
Support means for supporting the floor structure 16 in the
horizontal planar position of FIGS. 1 and 2 or in the
storage-transport position of FIGS. 3-5 includes a pair of skid
runners 45, one each secured to the center section 17 adjacent the
hinge connection 19, and a skid runner 46 secured to each of the
wing sections 18 spaced from the hinge connection 19 of a
respective wing section 18. All of the skid runners 45-46 extend
parallel to each other and to the pivot axes of the hinge
connections 19 of the wing sections 18. A short tongue element 47
is provided at the front edge of the center section 17 for
connection to a snowmobile or the like, not shown. On many
occasions, as when fishing is poor at one location, it may be
desirable to move the erect structure of FIGS. 1 and 2 to another
location. Inasmuch as the floor structure 16 is supported by the
skid runners 45, 46 it is a simple matter for one to connect a
snowmobile to the tongue element 47 and tow the ice fishing house
15 to a relatively close new location without collapsing the house.
Should the new location be some distance away or should it be
desired to store the ice fishing house 15, it is also a relatively
simple matter to collapse the house 15 from the erect operative
position of FIGS. 1 and 2 to the storage-transport position shown
in FIGS. 3-5 as will be described immediately hereinafter.
Referring to the diagrammatic views of FIGS. 10A-10G, the
sequential steps of collapsing the floor structure 16 and frame 20
from the upright operative position of FIGS. 1 and 2 to the
storage-transport position of FIGS. 3-5 are as follows. First, one
end of each of the angular brace members 42, 43 and 44 is detached
(such as shown in FIGS. 6 and 9) to permit the front and rear arch
members 27, 28 to collapse inwardly from the position shown in FIG.
10A to the position shown in FIG. 10B wherein the partially
collapsed arches are supported by the stabilizer members 34 in
their respective vertical planes. Next, the vertical stabilizer
members 34 are collapsed inwardly toward each other so as to lie in
a vertical plane perpendicular to and extending between the
vertical planes of the arch members 27, 28 (see FIGS. 10C, 10E and
10G). From FIGS. 10A-10G, it can be seen that while these
collapsing movements of the frame 20 are occurring, the folding
portions of the arch members 27, 28 assume generally symmetrical
positions on opposite sides of the stabilizer members 34. Thus, a
minimum of twisting or torque forces are applied to the hinged
members 36-38 and intermediate hinged members 39 in spite of the
fact that only a single person may be imparting collapsing
movements of the frame means 20. After the stabilizer members 34
have been moved to the position illustrated in FIG. 10G, the floor
structure 16 and frame means 20 assume the dotted line position of
FIG. 10D wherein the floor structure 16 is still in a generally
horizontal planar condition. Thereafter, it is a simple matter to
complete the folding of the ice fishing house to its
storage-transport position by moving first one of the wing elements
18 from the dotted line to the full line position position of FIG.
10D and connecting the angular brace member 43 associated therewith
in the manner shown in FIG. 3, and thereafter moving the other wing
section 18 from the dotted to the full line position of FIG. 10D
and securing the angular brace members 43 associated therewith in
the manner shown in FIG. 3. Finally, the brace members 42
associated with each of the wing sections 18 are secured to
auxiliary pin elements 48 projecting from the edge of the wing
sections 18 at the corners thereof removed from the hinged
connections 19 (see FIGS. 4, 5). As can be seen particularly in
FIGS. 3-5, the groups of angular brace members 42, 43 are connected
in X fashion to provide a storage-transport position in which all
the folding parts of the ice fishing house 15 are rigidly
maintained in position without loss or damage to them caused by
undue forces exerted on them during transport movements
thereof.
While a specific embodiment of a collapsible fish house is
illustrated and described, it should be understood that further
modifications and improvements will occur to those skilled in the
art. I desire it to be understood, therefore, that this invention
is not limited to the particular structure shown, and I intend in
the appended claims to cover all modifications which do not depart
from the spirit and scope of this invention.
