BACKGROUND
[0002] Many people prefer to observe or hunt large game animals
from the vantage point provided by an elevated platform in a high
tree. Such vantage points provide the opportunity to hunt and
observe wildlife while avoiding detection by big-game animals
roaming through the general vicinity of the platform-bearing
tree.
[0003] Climbing treestands are frequently used by hunters to ascend
tree trunks and provide an elevated platform on which to support
their weight during hunting. A climbing treestand is both a
climbing aid and, eventually, a platform supporting the climber in
the tree. These treestands typically rely on a cable or strap that
extends around a tree trunk to support the weight of the hunter
during ascension and subsequent hunting operations. It is common
for some climbing tree stands to include a top piece, upon which
the hunter may sit, and a bottom piece, configured to receive one
or both of the hunter's legs. The top and bottom pieces are used to
ascend a tree trunk using what is known as the "sit and stand"
technique.
[0004] In the "sit and stand" technique, a user alternately rests
his or her weight on one of the pieces while raising the other
piece with respect to the tree trunk. Thus, when the hunter's
weight is on the top piece and the bottom piece is being raised
with respect to the trunk, the hunter is sitting. Conversely, when
the hunter's weight is on the bottom piece and the top piece is
being raised with respect to the tree trunk, the hunter is
standing. Climbing tree stands are generally more versatile and
less dangerous than fixed tree stands, and consequentially enjoy
widespread usage by many large game hunters.

DETAILED DESCRIPTION
[0027] Notwithstanding the many benefits associated with climbing
treestands, users of climbing treestands available in the art often
encounter problematic situations. For example, tree trunks tend to
taper in diameter, becoming narrower as a climber ascends.
Typically climbing treestands include cables configured to extend
around the trunk of a tree. These cables are difficult to adjust or
may not be adjustable at all. Without adjusting the cable, the user
has very little control over the pitch of the climbing treestand,
which may vary substantially due to the change in tree trunk
diameter upon ascension of the tree.
[0028] An additional problem often encountered by users of climbing
treestands is that of encountering branches in a tree trunk upon
ascension of the tree. Generally, climbing treestands have only one
cable extending around the tree trunk, and therefore the maneuver
of dismounting and disassembling the treestand in order to move
around the branch may be unsafe. Typically treestand users faced
with this problem cut the branch off of the trunk, which in turn
causes damage to the tree, may cause a hazard on the forest floor,
and may startle or notify game of a hunter's presence.
[0029] To address the issues mentioned above, the present
specification describes a climbing treestand having a belt or cable
configured to extend around the diameter of a tree trunk. The belt
or cable is connected to the climbing treestand by at least one
connection mechanism. The connection mechanism allows for adjusting
the length of the portion of the belt or cable that extends around
the tree trunk, thus providing enhanced pitch control to a user.
The present specification further describes an example of a
climbing treestand having a first and second belt or cable on the
foot or platform section, configured to extend around a tree trunk.
The plurality of belts or cables allows for a user to safely
maneuver the treestand around branches and other obstacles
protruding from the tree trunk. The specification also addresses
portability issues by describing wheels, collapsible arms, straps
to carry the apparatus as a backpack, carrying bags, extendable
frames, and a telescoping handle.
[0030] In the following description, for purposes of explanation,
numerous specific details are set forth in order to provide a
thorough understanding of the present systems and methods. It will
be apparent, however, to one skilled in the art that the present
systems and methods may be practiced without these specific
details. Reference in the specification to "an embodiment," "an
example" or similar language means that a particular feature,
structure, or characteristic described in connection with the
embodiment or example is included in at least that one embodiment,
but not necessarily in other embodiments. The various instances of
the phrase "in one embodiment" or similar phrases in various places
in the specification are not necessarily all referring to the same
embodiment.
[0031] The principles disclosed herein will now be discussed with
respect to exemplary climbing treestand apparatus and systems for
climbing trees.
Exemplary Apparatus
[0032] Referring now to FIG. 1, an exemplary top portion of a
climbing treestand apparatus (100) is shown. The climbing treestand
apparatus (100) includes a main frame (140) having a first end
(110) and a second end (115). The first end (110) is configured to
engage a tree, and includes components generally forming a "V"
shape permitting the first end (110) to engage tree trunks having a
wide range of diameters. A sort of padding (112) made of
substantially resilient material, such as polyurethane, may be
placed on the first end (110) situated so that it will be between
the main frame (140) and the tree for better grip and protection of
the tree trunk. The second end (115) is configured to support the
weight of a user. In this case, the main frame is configured to
support the user's weight by providing a seat (145) for the user to
sit on during and after climbing operations. The second end (115)
may also provide attachments for a safety harness for safety in the
case of a fall. According to one example, the attachment may
include a ring (150) attached to the seat (145) that is configured
to support the user's weight. A safety harness may be attached to
the ring (150) securing a user to the tree stand. According to
another example, the ring (150) may be attached to the underside of
the seat (145). According to another example, the ring (150) may be
attached at any secure point to connect to any safety harness worn
by a user. Said ring can be attached at any secure point to connect
to any safety restraint harness worn by operator.
[0033] The main frame (140) may be partially or substantially made
out of a lightweight, strong composite material. In other
embodiments, the main frame (140) may be made out of metal.
[0034] The main frame (140) has attached to it first and second
arms (120, 125) to which a double locking cinch system (170) may be
attached. In this embodiment, the double locking cinch system (170)
includes a first toothed belt (105), made of resilient material,
which is removably attached with a first set of ratchet mechanisms
(130, 135). The first set of ratchet mechanisms (130, 135) are
configured to allow the user to selectively alter the length of a
portion of the first toothed belt (105) that runs between the first
and second arms (130, 135) for example, while ascending or
descending a tree. This portion of the first toothed belt (105) is
configured to extend around the back side of the tree, opposite the
side engaged by the first end (110) of the main frame (340).
Specifically, the first set of ratchet assemblies of this example
permit the movement of the first toothed belt (105) through the
ratchet mechanism (130, 135) in a direction that shortens the
length of at least a portion of the first toothed belt (105)
configured to extend around a tree. The portion of the first
toothed belts (105) configured to extend around the tree may be
lengthened by depressing a ratchet pawl, as will be shown in more
detail in subsequent figures. In this example, the first toothed
belt (105) is positioned on a side of the tree opposite the main
frame (140).
[0035] Similarly, the double locking cinch system (170) may include
a second toothed belt (155), made of resilient material, that is
removably attached to the main frame (140) with a second set of
ratchet mechanisms (160, 165) configured to secure the climbing
tree stand to the tree. The second toothed belt (155) and second
set of ratchet mechanisms (160, 165) are configured to shorten a
portion of the length of the second toothed belt between the
ratchet mechanisms (160, 165). In this example, the second toothed
belt (155) is positioned on front side of the tree, that is the
same side engaged by the first end (110) of the main frame (340).
In this fashion the first toothed belt (105) and the second toothed
belt (155) together encompass the circumference of the trunk of the
tree. According to this example, after the first toothed belt (105)
has been adjusted to achieve the desired pitch, the second tooth
belt (155) may be adjusted to tighten around the trunk of the tree.
Doing so increases friction between the tree and the climbing tree
stand to more rigidly secure the device (100) to the tree and to
prevent slippage of the device when the operator has reached the
position desired. This increases the safety of the device (100) and
further reduces the environmental impact of the device on the
tree.
[0036] According to one example, the second toothed belt (155) and
the second set of ratchet mechanisms (160, 165) may be attached to
the first toothed belt (105) after the stand has been placed on the
tree. According to another example, the second set of ratchet
mechanisms (160, 165) may be attached to the first toothed belt
(105). In this example a portion of the second toothed belt (155)
is inserted into the ratchet mechanisms and tightened after the
stand has been placed on the tree and the desired position
reached.
[0037] Prior art has described multiple belt attachments located at
the proximal portion near the front of the stand platform without a
ratchet mechanism. Thus it is not intuitively obvious to one
skilled in the art as the attachment at the front of the platform
would require the operator to face away from the tree to bend over
placing full weight on the front of the stand making it dangerous
and impossible to release the belt attachments. In this art the
operator remains in contact with and facing the tree placing his
weight on the back portion of the stand platform and in contact
with the hand portion of the device allowing weight to be taken off
the stand portion of the platform thus allowing the release and
operation of the ratchet mechanism. This mechanism describes art
not heretofore described in prior patent art In addition this
device describes a third belt attached to the upper belt which has
a second double ratchet mechanism which can be cinched closing the
space from the front of the tree as well as the back of the tree
allowing the belts to be securely attached to the tree in order to
prevent slippage of the device when the operator has reached the
position desired. This tightening mechanism has not been described
in prior art nor has the tightening opposite direction ratchet dual
belt mechanism. This ratchet mechanism is not solidly attached to
the tree stand or hand climber mechanism, but instead is attached
to the belts after the stand has been placed on the tree. These
mechanisms are also applicable in tree stands which are not self
climbing by design but rather those referred to as strap on
stands.
[0038] As will be apparent to one skilled in the art, there are
variations on the type of belt or cable that may be used in the
double locking cinch system (170) to hold the treestand apparatus
(100) and user against the trunk of the tree. For example, as an
alternate to the toothed belts (105, 155) and ratchet mechanisms
(130, 135, 160, 165), the first and second arms may receive a
synthetic or metal cable with spring activated compression grips.
The cable or belt used will be able to bear the weight of the
treestand and user. The cable or belt may also be made of resilient
material that will withstand the wear and tear of use in outdoor
environments, scraping against tree trunks, and frequent belt or
cable length adjustment.
[0039] The arms (120, 125) may be collapsible angular extensions of
the main frame (140). The arms (120, 125) may be attached to the
main frame by hinges or pins (127, 128) that allow the angular
rotation of the arms. A support weldment (121) forming a "V" shape
may be attached to the arms (120, 125) to support them in their
extended positions. The support weldment (121) may be attached to
the arms (120,125) by hinge like connectors or pins (123, 124) to
allow the rotation of the weldment (121) from collapsed to extended
positions. These hinges or pins (127, 128, 123, 124) may be
sufficiently strong to support the weight of an individual and
his/her gear. The weldment (121) may be removably attachable to the
main frame (140) by a connector (126) that receives a hole (122) in
the weldment and holds the arms (120, 125) in extended position.
The connector (126) may be, for example, a bolt and wing-nut
combination for quick removal and attachment.
[0040] The embodiment further comprises bolts (141) to attach to a
bottom portion of the treestand. The bolts (141) may be placed on
the main frame (140) with the threaded portion facing down or away
from the face where the arms (120, 125) are attached. As will be
apparent to one skilled in the art, the bolts (141) may be replaced
by other suitable connectors, such as pins or hooks. The attachment
of the treestands will be discussed later in further detail.
[0041] Referring now to FIG. 2, a perspective view of the exemplary
top portion (100) of the climbing treestand apparatus is shown. The
double locking cinch system (170) been left out for simplicity and
the arms (120, 125) are shown in extended position. In extended
position, the weldment support (121) is attached to the main frame
via the bolt (126) as previously discussed. The hinges or pins
(123, 124, 127, 128) that attach the arms to the weldment and main
frame create a triangle of support with the bolt attachment (126)
for rigidity in the extended position. The support weldment (121)
can be detached and rotated forward or backwards to allow the arms
(120, 125) to be collapsed. The arms (120, 125) are meant to be in
extended position when engaging a tree and collapsed position for
transport.
[0042] Referring now to FIG. 3, an exemplary bottom portion of a
climbing treestand apparatus (300) is shown. The climbing treestand
apparatus (300) includes a main frame (340) having a first end
(310) and a second end (315). The first end (310) is configured to
engage a tree, and includes a "V" shape and padding (312), similar
to that of the embodiment shown in FIG. 1. Furthermore, the second
end (315) of the main frame (340) is configured to support a user's
weight by providing foot straps (365) to attach the user's feet to
the main frame (340) and allow the user to stand on the main frame
(340).
[0043] The main frame (340) may be made of some sort of metal or
substantially or partially fabricated from a lightweight, strong
composite material to provide versatility in transporting the
climbing treestand apparatus (300).
[0044] The exemplary bottom portion of the climbing treestand
apparatus includes a pair of belts or cables. Specifically in FIG.
3, the apparatus (300) includes first and second toothed belts
(305, 307) made of resilient material, both of which are removably
attached to first and second arms (330, 335) of the main frame
(340), with ratchet mechanisms similar to those discussed in
relation to FIG. 1. The ratchet mechanisms, or equivalent
attachment mechanisms, allow the user to selectively alter the
length of the portion of the first and second toothed belts (305,
307) between the first and second arms (330, 335) of the main frame
(340). These portions of the toothed belts (305, 307) are
configured to extend around the tree engaged by the first end (310)
of the main frame (340).
[0045] The toothed belts (305, 307) may be independently
adjustable. One of the toothed belts (305, 307) may be disengaged
from the main frame (340) while another of the toothed belts (305,
307) maintains its position extending around the tree trunk and
attached to the main frame (340) allowing the treestand to remain
secured to the tree while one of the belts is not attached.
[0046] Again, as discussed in relation to FIG. 1, alternate belts
or cables along with alternate attachment mechanisms may also be
used in place of the depicted toothed belts (305, 307) and ratchet
mechanisms.
[0047] The exemplary treestand apparatus (300) further includes
wheels (345, 350) that may be used to conveniently transport the
treestand apparatus (300) on the ground. In one embodiment, the
wheels (345, 350) may be used in conjunction with a pop-up handle,
similar to those used with many suitcases. A pop-up handle may be
mounted, for example, on the underside of the main frame (340).
[0048] In this embodiment, the arms are collapsible in a similar
manner to that shown in FIG. 1. The apparatus includes a support
weldment (331) with a hole (332) that can be received by a
connector (336) when the arms (330, 335) are in extended
position.
[0049] The embodiment further comprises threaded holes (341) to
receive the bolts (141, FIG. 1) from the top portion of the
treestand. The top (100, FIG. 1) and bottom (300, FIG. 3) portions
of the treestand may be attached for portability as will be
displayed in a later drawing. Once again, a variation on the
threaded holes (341) may be used depending on the connecting
mechanism used to attach the tree stands. For example, if hooks or
pins were used on the top portion (100, FIG. 1), corresponding
hooks or holes may be used on the bottom portion (300).
[0050] Referring now to FIG. 4, a perspective view is shown of the
bottom portion of the treestand apparatus (300) of FIG. 3. The
toothed belts (305, 307, FIG. 3), or comparable cables or belts,
are left out for simplicity. The arms (330, 335) are shown in
extended position with the support weldment (331) attached to the
main frame via the connector (336). The arms (330, 335) are
attached to the main frame (340) and support weldment (331) by
hinges or pins (405, 406, 407). The last hinge or pin connecting
the support to one of the arms (330) is not in view.
[0051] The first and second arms (330, 335) are shown to include
housings (410, 415, 420, 425) for the ratchet assemblies by which
the toothed belts (305, 307, FIG. 3) are attached to the first and
second arms (330, 335). If alternate belts or cables are used,
assemblies used for the attachment of the said belts or cables may
be placed in a similar location, with attachments located ideally
proximal to the tree.
[0052] With reference to toothed belts and ratchet assemblies, and
as will be similar to other cable or belt configurations, the
ratchet assemblies permit the free movement of the toothed belts
(305, 307 of FIG. 3) through the ratchet housings (410, 415, 420,
425) in one direction and prevent movement of the toothed belts
(305, 307, FIG. 3) in a second, opposite direction. Movement by the
toothed belts (305, 307, FIG. 3) in the second, opposite direction
may be accomplished by pressing the lever, cam, or pawl of the
ratchet assembly concurrent to the movement.
[0053] Specifically, the ratchet assemblies of this embodiment
permit the movement of the toothed belts (305, 307, FIG. 3) through
the ratchet housings (410, 415, 420, 425) in a direction that
shortens the length of at least one of the portions of the toothed
belts (305, 307, FIG. 3) configured to extend around a tree. The
portions of the toothed belts (305, 307, FIG. 3) configured to
extend around the tree may be lengthened only by depressing a
ratchet pawl, as will be shown in more detail in subsequent
figures.
[0054] Referring now to FIG. 4a, a perspective view is shown of an
exemplary bottom portion of the climbing tree stand (300) of FIG.
3. The toothed belts (305, 307, FIG. 3), or comparable cables or
belts, are left out for simplicity. In this example, a portion of
the second end (315) is extendable beyond the main frame (340).
This enables the frame to be collapsed for transportation and
extended when mounted on a tree. According to this example, the
frame of the second end (315) inserts into the main frame at a
joint (430, 432). The second end (315) includes a number of
adjustment holes (440) with corresponding adjustment holes (442) in
the main frame. The adjustment holes (440, 442) allow for the
selection of the length that the second end (315) extends beyond
the main frame (340). A locking connector (450) secures the second
end (315) to the main frame (340) when the adjustment holes (440,
442) are aligned. As will be apparent to one skilled in the art,
there are variations on the type of locking connector (450) that
may be used to secure the second end (315) to the main frame (340).
Examples of locking connectors include, but are not limited to, a
nut and bolt, bolt and cotter pin, and a spring-loaded pin.
[0055] FIG. 5 is an illustration of an exemplary first end (510) of
FIG. 1, used to secure the climbing tree stand to the tree. Certain
elements, including the support weldment (121) have been left out
for simplicity. The first end (510) includes arm components (512,
514) generally forming a "V" shape permitting the first end (510)
to engage generally circular tree trunks having a wide range of
diameters. Attached to the arm components (512, 514) are a pair of
band supports (516, 518) which may rotate. The band supports (516,
518) permit the first end (510) to engage tree trunks having a wide
range of diameters. The band supports (516, 518) may be attached to
the arm components (512, 514) by hinges or pins (520, 522) that
allow angular rotation of the band supports. A band (524) made of
substantially resilient material, such as polyurethane, may be
coupled to the band supports (516, 518) so that it will be between
the band supports and the tree for better grip and protection of
the tree trunk. The first end (510) may be used to secure the top
portion (FIG. 1, 100), and the bottom portion (FIG. 3, 300) to the
tree.
[0056] FIG. 6 is an illustration of an exemplary first end (610)
used to secure the climbing tree stand to the tree. Certain
elements, including the support weldment (121) have been left out
for simplicity. The first end (610) includes arm components (512,
514). Attached to the arm components (512, 514) are a pair of
support braces (612, 614) which may rotate. The support braces
(612, 614) may be attached to the arm components (512, 514) by
hinges or pins (616, 618) that allow angular rotation of the
support braces. Connected to the support braces (612, 614) are a
pair of band supports (516, 518) which may rotate. Similarly the
band supports (516, 518) may be attached to the support braces
(612, 614) by hinges or pins (620, 622) that allow angular rotation
of the band supports. The support braces (612, 614) and the band
supports (516, 518) permit the first end (610) to engage tree
trunks having a wide range of diameters. The first end (610) also
includes the band (524). The first end (610) may be used to secure
the top portion (FIG. 1, 100), and the bottom portion (FIG. 3, 300)
of the climbing tree stand to the tree.
[0057] Referring now to FIG. 7, an exemplary attachment mechanism
(700) that is used to attach a belt or cable to the treestand arms
(335, 330 FIGS. 3 and 120, 125 FIG. 1) is shown. The attachment
mechanism (700) may also be used in the double locking cinch system
(170, FIG. 1) to attach the top portion (100) to a tree, and to
stabilize the tree stand to a tree through the second toothed belt
(155, FIG. 1). As described above, the double locking cinch system
(170, FIG. 1) includes first and second toothed belts (105, 155,
FIG. 1) that when fed through a first and second set of ratchet
mechanisms (130, 135, 160, 165, FIG. 1) respectively allow the
second toothed belt around the front of the tree to remain slack
while climbing, while the second toothed belt encircling the back
side of the tree may freely move up and down the trunk of the tree.
Once a desired position has been reached, the second toothed belt
may be tightened against the front side of the tree. This mechanism
is not simply a circular belt but instead two different belts each
fed through the double belt ratchet mechanism allowing the forward
belt around the front of the tree closest to the operator to remain
slack while climbing, while the belt encircling the back side of
the tree away from the operator to move freely up and down the tree
using the sit and stand climbing technique to place weight on or
off the stand in a wedging fashion. The forward belt will have the
slack removed by the ratchet mechanism by manual engagement by the
operator when secure attachment to the tree is desirable. The
attachment mechanism (700) includes a housing (710), a pawl (705),
a pivot pin (715), a spring (725), and a spring pin (720). The
spring (725) has one end in contact with the ratchet housing (710)
and another end that engages the pawl (705). The following figures
will give specific details regarding attachment mechanisms for
different belt or cable types.
[0058] A belt or cable may be fed through the housing (710) where
it is engaged by the spring-loaded pawl (705) and restricted. An
outer end of the pawl (705) provides a lever which may be depressed
by the user to disengage the pawl (705) from the toothed belt (305,
FIG. 3) and permit the toothed belt (305, FIG. 3) unrestrained
movement in either direction through the housing (710). As used in
the double locking cinch system, two attachment mechanisms (700)
are employed, each facing a different direction. In this fashion,
one attachment mechanism may be used to attach the climbing tree
stand to a tree. The second attachment mechanism may then be
tightened against the tree, offering a more secure attachment of
the climbing tree stand to the tree.
[0059] The ratchet mechanism (700) depicted in this embodiment has
internal and external portions which allow easy inspection and
replacement of the parts of the ratchet mechanism.
[0060] Referring now to FIG. 8, a side view of an attachment
assembly (800) that is configured to engage toothed belts is shown.
The attachment assembly (800) for toothed belts will also be
referred to as a ratchet assembly. The ratchet assembly (800) is
shown in conjunction with a toothed belt (305). The housing (710,
FIG. 7) and spring elements (720, 725, FIG. 7) have been removed to
better illustrate the interaction between the ratchet pawl (805)
and a toothed belt (305).
[0061] The pawl (805) has a recess (810) designed to engage
individual teeth (815) of the toothed belt (305). The geometries of
the teeth (815) and the pawl (805) are such that movement of the
toothed belt (305) to the right is possible. The spring-loaded pawl
(805) locks the toothed belt (305) into position by preventing it
from moving to the left as long as the pawl (805) has engaged one
of the teeth (815). When a leftward motion of the toothed belt is
desired, the pawl (705) must be disengaged by rotating it
counterclockwise about the pivot pin (715). This rotation may be
accomplished by depressing the top of pawl (805).
[0062] Referring now to FIG. 9, a side view of an attachment
assembly (900) that is configured to engage a non-toothed belt or
cable is shown. The attachment assembly (900) for a non-toothed
belt or cable will also be referred to as a compression grip
assembly. The compression grip assembly (900) is shown in
conjunction with a non-toothed belt or cable (910). The housing
(710, FIG. 7) and spring elements (720, 725, FIG. 7) have been
removed to better illustrate the interaction between the
compression grip pawl (905) and a non-toothed belt or cable
(910).
[0063] The geometry of the pawl (905) is such that movement of the
belt or cable (900) to the right is possible. That is, if the belt
or cable (910) is pulled to the right, the friction between the
pawl (905) and the belt or cable (910) will reduce the compression
of the belt or cable (910) and allow the right-ward movement.
However, the geometry of the pawl (905) inhibits the movement of
the cable or belt (910) to the left. The spring-loaded pawl (905)
along with friction between the pawl (905) and belt or cable (910)
locks the belt or cable (910) into position by preventing it from
moving to the left as long as the pawl (905) sufficiently
compresses the belt or cable (910). When a leftward motion of the
belt or cable (910) is desired, the pawl (905) must be disengaged
by rotating it counterclockwise about the pivot pin (715). This
rotation may be accomplished by depressing the top of pawl
(905).
[0064] Referring now to FIG. 10, the treestand (1000) consists of
the top (100) and bottom (300) portions of the treestand. Both
portions (100, 300) of the treestand are collapsed and attached for
portability. The dotted lines are used to distinguish each portion
of the tree stand (100, 300). The bottom portion of the treestand
in this view comprises the mainframe (340), an arm (330), the
support weldment (331), and a wheel (345). The top portion (100) in
this view comprises the main frame (140), the arm (120), the
support weldment (121), and attachment bolts (141). Using the
attachment bolts (141) and the receiving bolt holes (341, FIG. 3),
the portions are attached firmly together. The collapsibility and
attachment of the frames allows for easy portability of the
treestand.
[0065] Referring now to FIG. 11, an exemplary climbing treestand
apparatus (300) is shown mounted on the back of a user (1105) with
shoulder straps (1110, 1115).
[0066] Referring now to FIG. 12, the exemplary climbing treestand
(1000) is shown pulled by a user (1205). The attached climbing
treestand apparatus (1000) may be rolled on wheels (350) behind a
user (1005) holding onto the main frame (340, FIG. 3) of the bottom
portion (300) of the treestand. Although not shown in this figure,
an extendable handle similar to that used on luggage may also be
included. Luggage bags (not shown) may also be attached to the
stand (1000) in which the stand may be placed and carried or
checked as a piece of airline luggage. Additional bags may also be
incorporated onto the stand such as a detachable fanny pack, or
pouches for holding needed items while ascending, descending, or
waiting for game in the stand.
Exemplary System
[0067] FIGS. 13-17 illustrate an exemplary system (1300) for
climbing a tree (1305) in various stages of ascending a tree. The
system (1300) includes first and second climbing treestand
apparatus (100, 300). Each climbing treestand apparatus (100, 300)
has a main frame and extending arms.
[0068] The first climbing treestand apparatus (100) is configured
to support a user's weight with the user sitting thereon, and has a
double locking cinch system (170). Included in the double locking
cinch system is a first toothed belt (105) attached to the
extending arms at two points with ratchet mechanisms. A portion of
the toothed belt (105) extends around the back side of the tree
(1105) thereby securing the apparatus (100) to the tree. The second
tooth belt (155) attached to the extending arms at two points with
other ratchet mechanism. A portion of the second toothed belt (155)
extends around the front side of the tree opposite the portion
surrounded by the first toothed belt. With the first toothed belt
(105) adjusted as desired, the second toothed belt (155) tightens
against the tree to further secure the climbing treestand apparatus
(100) to the tree. In this arrangement the first toothed belt (105)
may be released to pass around the back of the tree and over any
limbs which are encountered during the ascent or descent of the
tree. In this arrangement the second of the two belts can be
released to pass around the back of a tree and over any limbs which
are encountered during the ascent or descent of the tree. After the
second belt is passed around the tree and over an obstacle such as
a limb, the first belt is released until the operator has cleared
the obstacle. The second belt is then reattached and secured to
allow a double belt system to continue the climb and thus be ready
for the repeat of the process when another obstacle is encountered.
This system has not been described in prior art. It is not
intuitively obvious to one skilled in the art as no prior art has
described the necessity of a double belt and ratchet mechanism to
overcome the above described obstacles encountered during the
related activities. In addition this device has a belt attachment
at the base of the stand platform which engages contact with the
tree. The double swivel belt attachment allows a more secure grip
to the tree without damaging the tree. Other prior art has
described metal teeth and solidly attached rubber posts. These
damage the trees and do not allow the cradling action of the belt
to securely adhere to the tree without damage to the tree.
[0069] The second climbing treestand apparatus (300) is configured
to support the user's weight with the user standing thereon. The
second apparatus (300) has two toothed belts (305, 307), which,
similar to the first apparatus (100), are each attached to the arms
of the second apparatus at two points with ratchet mechanisms. A
portion of each of the toothed belts (305, 307) extends around the
tree (1305).
[0070] The exemplary system (1300) is configured to allow a user to
climb the tree (1305) using the "sit and stand" technique, in which
the first and second apparatus (100, 300) serve to alternately
ascend or descend the tree trunk and provide support for the weight
of the user. This and other similar techniques are known in the
art. The user is not shown in the figures for clarity.
[0071] Referring now to FIG. 13, the system (1300) is shown
ascending the tree (1305) with a branch (1310) as a potential
obstacle to the system (1300). To continue ascending the tree
(1305), the first or upper climbing treestand apparatus (100) must
be manipulated around the branch (1310). To do so, the toothed belt
(105) may be disengaged from the main frame using the ratchet
mechanism. While the second apparatus (300) supports the user's
weight, the first apparatus (100) may then be secured to the tree
above the branch (1310) and the toothed belt (105) reattached to
the main frame with the ratchet mechanism.
[0072] Referring now to FIG. 14, the system (1300) is shown with
the first apparatus (100) above the branch (1310), and one of the
toothed belts (307) of the second apparatus (300) disengaged. The
toothed belt (307) may be disengaged from the arm using the ratchet
mechanism. Once disengaged, the loose toothed belt (307) may be
manipulated over the branch (1310) and reengaged into the main
frame, while maintaining a constant anchor to the tree (1305) from
the other toothed belt (305) of the second apparatus (300).
[0073] Referring now to FIG. 15, the system (1300) is shown with
the first climbing treestand apparatus (100) and one of the toothed
belts (307) of the second climbing treestand above the branch
(1310). The second belt (305) is still engaged and attached below
the branch.
[0074] Referring now to FIG. 16, the system (1300) is shown with
the toothed belt (305) that was beneath the branch (1310)
disengaged from the main frame, while the second climbing treestand
apparatus (300) is being supported by the engaged toothed belt
(307) above the branch (1310).
[0075] Referring now to FIG. 17, the system (1300) is shown with
all of the toothed belts (105, 155, 305, 307) connected to their
corresponding treestand climbing apparatus (100, 300) above the
branch (1310). Using ratchet mechanisms in conjunction with toothed
belts (105, 305, 307) the treestand apparatus (100, 300) may be
successfully and safely manipulated around obstacles such as
branches (1310).
Exemplary Methods
[0076] Referring now to FIG. 18, an exemplary method (1800) of
climbing a tree is shown. The method (1800) includes the step of
providing (step 1805) a tree-climbing system, as described in
relation to FIG. 13. A user's feet are then coupled (step 1810) to
the tree-climbing system. The user then ascends (step 1815) the
tree, compensating (step 1820) for a diminishing tree trunk
diameter by using two attachment mechanisms to shorten the length
of the belts or cables extending around the tree.
[0077] Referring now to FIG. 19, another method (1900) of climbing
a tree is shown. The method includes the step of providing (step
1905) a tree-climbing system as described in relation to FIG. 13. A
user's feet are coupled (step 1910) to the system, and the user
then ascends (step 1915) the tree, alternately disengaging (step
1920) the belts or cables to manipulate the system around an
obstacle in the tree.
[0078] The preceding description has been presented only to
illustrate and describe embodiments and examples of the principles
described. This description is not intended to be exhaustive or to
limit these principles to any precise form disclosed. Many
modifications and variations are possible in light of the above
teaching.
