The present disclosure relates generally to the field of hunting, wildlife viewing, and climbing and in particular to an apparatus, system, and method for safely climbing to a higher location.
None
A climbing apparatus is often used in hunting to aid in achieve a higher vertical position for better visibility, improved concealability, and improved target angles. The climbing apparatus is typically used to aid a person in scaling a vertical member such as a tree or pole. Three typical versions of a climbing apparatus include a hang-on tree stand (also referred to as hang-on platform style), a climbing tree stand, and a tripod. Existing hang-on tree stands, although suitable for most trees and can be small and compact, have risky two-handed set up and generally do not offer a harnessed climbing/setup which makes them unsafe. A standard climbing tree stand allows for ground level set up and increased height capacity, however, they typically require a certain type of tree with limited or no branches, do not function well when trees taper, and tend to be bulky. A tripod style tree stand requires timely set up, are at a fixed height and usually not very portable.
Current devices offering portability are often bulky and lack an integrated solution. Hang-on platform styles require separate large climbing sticks that were not necessarily made to work together. During climbing and assembling of the climbing sticks the climber's ability to secure themselves in case of a fall is limited and complicated if possible at all. Further the platform must be affixed at an elevated level with limited use of the hands. This usually requires the climber to leave the platform on the ground while ascending with a tow line. Once at the desired position the climber retrieves the platform via the tow line while holding on with one hand. Altogether this is a complicated, physical, and time consuming task which is further complicated during low light installation periods.
Climbing stands are bulky and require an ideal vertical member therefore limiting the number of available trees. This member cannot have any horizontal members, such as branches, between the ground and the desired position. A cross section of the tree is preferred to be consistent or have very little taper from bottom to top. This is because it is difficult to adjust the gripping system safely once elevated. It is also advantageous to have a relatively smooth and robust surface on the vertical member. Finding the right tree is therefore difficult. These types of stands cannot be left unattended where security is a concern and it is not possible to leave them elevated to reduce the chance of theft.

For purposes of summarizing the disclosure, certain aspects, advantages, and novel features of the disclosure have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one embodiment of the disclosure. Thus, the disclosure may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the disclosure which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present disclosure will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments and method(s) of use for the present disclosure constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present disclosure will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
The present disclosure provides for a system and a climbing apparatus used to aid a person in scaling a vertical member or climbing structure such as a tree or pole. In an example, the climbing apparatus is comprised of a multi-piece mast and trolley system. The mast can be broken down into a plurality of detachable mast segments that stack and secure to each other to allow for a vertical accent. The trolley then follows and securely slides up the mast. In an example, the trolley portion is modular and load bearing. The trolley should be made operable to support multiple embodiments to be used individually or as a system. The trolley or set of trolleys should be constructed to support a user (i.e., a climber), a handle, a supporting rail (shooting rail), a seating assembly, and/or platform to support a climber. The trolley can have an integrated or separately adapted guide feature to keep the trolley restricted to following a mast. The trolley can include mechanical or electro-mechanical braking, binding, or latching function to control the ascent or decent of the climber. The system often includes at least one upper trolley and at least one lower trolley. The upper trolley can also support attachment of a climbing harness and/or repelling gear. A platform trolley can further be provided to give support to broken down mast sections and/or gear. The mast segments can be taken apart to allow for folding to create a compact shape for easy packing and handling. Further attachments are equipped to accommodate shoulder and hip straps for back packing comfort. In yet another form of the present disclosure, a platform, handle, and/or supporting rail trolley are provided that can be equipped with a padded seat for added comfort and/or convenience.
In this example, the mast includes a plurality of mast segments that can be disassembled and compact easily together to promote packing convenience. Mast segments are typically elongated metallic, alloy, and/or plastic/composite members that define by various cross sections for supporting the trolley. Two detachable mast segments can be combined by inserting a reduced cross section end, also referred to as a tapered end, of one mast portion into a standard cross section end of a second mast portion. This forms mating ends with a male and female end portions sized and shaped to provide a stackable mast segment. This can be repeated until a desired climbing height is reached and thus forming a climbable mast. Each mast segment has a support piece for attachment to a vertical member or climbing object existing at the standard cross section end. Optionally, a singular hole opposite of the support piece can be used as a fail-safe preventing trolley travel past a final portion.
In an example of operating the climbing apparatus of the present disclosure for hunting or climbing a tree, the detachable mast segments offer a benefit. Having detachable and sometimes shorter mast segments to form an elongated vertical mast allows for climbing of a variety of trees including ones considered “imperfect” of varying diameter and straightness. This allows for a tree selection that offers other advantages like better concealment or hiding.
The present disclosure provides for using a hand trolley and platform trolley together along the mast. This allows for a climber to scale a vertical member, such as tree or otherwise. The platform is adapted to support the climber's weight while the hand trolley is advanced along the mast. The hand trolley supports the weight of the climber (and any belongings carried by the climber) while the platform trolley is advanced upward. In a further example, the apparatus can be designed for self-advancement through the utilization of an electro-mechanical system.

The present disclosure provides for a portable and collapsible climbing system, assembly, and apparatus operable to assist in reaching a higher vantage point which is useful and advantageous for sports like hunting. In one example, a climbing apparatus 10 includes a mast 11 adjustably connected to a stand platform 15 and a hand trolley 13. Mast 11 extends upwardly from a base level, typically the ground. Mast 11 is fabricated from material strong enough to support a platform assembly 15, a user of apparatus 10 (i.e., a climber), and any equipment carried by the user. A total weight of a user, equipment, and the platform assembly may exceed 200 lbs. and in some circumstances, the total weight exceeds 300 lbs. Mast 11 can be fabricated from a material selected from the group consisting of metal (steel, steel alloys, aluminum, aluminum alloys, etc.), plastic, composite materials, and the like.
Mast 11 is formed of detachable mast segments 12 that connect vertically in a relatively linear progression upwardly. Segments 12 can be fixed, as shown in
As shown in
In this example, mast 11 is formed of a plurality of mast segments 12 defining a length of about 24 inches. Each segment 12 is stacked on top of an adjacent segment 12 through a tapered connection 23 inserted into the opening formed at upper end 12A.
Apparatus 10 further includes at least one trolley 13 operable for moving up and down along mast 11. Trolley 13, as shown in
As shown in
Climbing apparatus 10 further includes a platform assembly 15 having a platform 16 connected to a seat 17 through a frame 19. In one form, frame 19 can be an H-frame for added stability and support or a single post 19A as shown in
Assembly 15 further includes a lower trolley 18 that effectively functions like upper trolley 13 having the same components such as a handle, a brake mechanism, and brake body connected to the mast 11. The lower trolley 18 is mounted to the H-frame and positioned between the support posts that form the H-frame.
During climbing, a user can secure their feet (virtual feet 20) to platform 16 by placing their feet 20 under the strap 21 and facing the mast 11. The user can manually raise handle 14 upwardly by disengaging the brake mechanism 28 of upper trolley 13 and sliding it upward along mast 11. When the trolley 13 stops either through braking action or by engaging the catch 33 into the travel hole 25, the user can then pull platform assembly 15 upward by temporarily holding their weight on trolley 13 with their hands and pulling the platform assembly 15 with their feet 20 until the platform locks into place on mast 11. This action is then repeated until a desired height along mast 11 is reached. The mast segments 12 are then added one by one as the user ascends upwardly. This process is reversed for coming down the mast 11. In this example, the upper trolley 13 and lower trolley 18 function independently with respect to each other and thus allow a degree of freedom for the user. Moreover, each time a mast segment 12 is added, a strap (not shown) can be used to secure mast 11 to the climbing object T. The apparatus 10 further allows for the user to secure their body to the mast 11 through a safety harness (not shown) connected to one or both trolleys.
Referring to
Referring to
In the example of
In yet a further example, a harness attachment point 47 is shown positioned above the saddle 40 thus allowing for securing a user harness (not shown) to the mast 11. The harness attachment point 47 is mounted to another trolley to further allow for independent movement up mast 11. This embodiment shows that a plurality of trolleys can be utilized to move up and down the mast 11 for added climbing features and customization of apparatus 10.
In yet another example, as shown in
Ladder mast segment 112 includes a pair of parallel and spaced apart squared rails 119 that extend upward and are connected by a plurality of horizontal bridge segments 121. The ladder trolley assembly 113 includes a ladder catch handle 114 and an optional tilt bracket 115. A catch 116 is provided to engage the bridge segment 121 as the trolley 113 moves upward along the mast segment 112. Ladder mast segment 112 further includes a spacer 120 for abutting against tree or another object. The ladder trolley assembly 113 defines a squared bracket portion that engages around the rails 119. A space is formed to allow for movement up and down over the spacer 120 when moving from one segment 112 to the next. Lower section 112A is reduced in size and/or tapered to mate with and securely next and engage with an opposite upper section of an adjacent mast segment 112 thus allowing for vertical stacking.
Rectangular latch segment 212 defines a rectangular cross section forming an opening for receiving a latch type trolley assembly 213 Latch trolley includes a squared handle 214 and a latch connector feature 215. The latch connector feature 215 is spring loaded by latch spring 216 that forces the latch connector features to extend outwardly and into the plurality of latch holes 225 positioned along the outer rails 219 of the latch segment 212. The latch features 215 include a ramped surface to recess inward against the spring when actuated by the handle so trolley 213 can move upward along mast segment 212. When the feature 215 is aligned with a hole 225, the force of the spring 216 causes the features to extend and protrude outwardly engaging and locking into the rails 219. A catch 217 allows for the features 215 to be retained to lower trolley 213 down the mast segment 212. Pulling up on the catch 217 releases the latch 215 to protrude outwardly engaging and locking into the rails 219. Mast segment 212 further includes a hinged connection 190 and 191 positioned at opposite ends that mate with an adjacent mast segment 212 to securely engage with an opposite hinged connection 190 and 191 of the adjacent mast segment 212 thus allowing for vertical stacking.
The various examples of a climbing apparatus, system, and method of the present disclosure provides for several advantages over existing products including but not limited to:
It is important to note that various combinations of the disclosed features and components are contemplated and within the scope of the present disclosure. For example, a plurality of trolleys can be included in an example climbing apparatus 10 for the climbing of a plurality of components including a harness attachment point, a seat or saddle, a platform or other components. Each trolley can be independent from any other trolley or ganged together or any combination thereof and can be powered by a motor or manually. Moreover, each trolley can include a different brake mechanism from any other trolley.
It should be noted that the steps described in the method of use can be carried out in many different orders according to user preference. The use of “step of” should not be interpreted as “step for”, in the claims herein and is not intended to invoke the provisions of 35 U.S.C. § 112(f).
