The present invention relates generally to a climbing apparatus and system for climbing columnar structures such as poles, trees and masts.
Climbing tree stands, pole-climbing shoes and climbing stick systems are known in the art. These systems and apparatus are used to assist in ascending and descending columnar structures in a variety of recreational and industrial applications. Pole-climbing shoes, for instance, are frequently utilized in the climbing of utility poles, masts and palm trees; while climbing tree stands and climbing sticks are routinely used by hunters, photographers and bird watchers. Generally, these systems are intended to allow their users to reach desired heights in a safe and rapid manner to hunt, observe, provide maintenance, and the like.
While climbing tree stands have been in existence for some time, it is believed they can have certain shortcomings. For example, climbing tree stands can be cumbersome, difficult to attach to the tree, and can require complicated climbing motions. During operation, the user generally raises and lowers the tree stands by alternating engagement of upper and lower frame members along the tree, for example, as shown and described in U.S. Pat. Nos. 3,955,645, 4,969,538 and 7,802,654. Because climbing tree stands typically have greater mass and greater overall dimensions than other types of climbing apparatus, they can be more difficult to pack and carry to and from remote climbing sites. The complexity of climbing tree stands can also limit their practical maneuverability along trees, which can have varying diameters along their length, can be divided along their length, can extend at an angle, and can have projections such as branches. Still further, the complicated climbing motions can require a user to either repeatedly take a seated position or support themselves with their upper body while they move the lower frame member. Due at least in part to the above-described disadvantages, the use of climbing tree stands can be tiresome and provide for slow movement along a tree.
Pole-climbing shoes are also believed to have drawbacks. Generally, pole-climbing shoes have a harness that attaches to or around a shoe, and a serrated gripping device, such as shown and described in U.S. Pat. Nos. 857,430, 3,078,951, 3,726,360, 5,249,644 and 5,417,306, and India Pat. No. 299,829. Users can move upward or downward along the columnar structure in an alternating stepwise manner. In most of these systems, a fastening loop is located around the columnar structure which the user can hold and move during each step. The gripping devices engage the sides of the columnar structure as the user steps upwardly or downwardly. However, it is believed pole-climbing shoes can be unstable, limited in use to certain diameters of columnar structures, and the harness and gripping device can be difficult to attach and remove from both the shoes and columnar structure. Furthermore, pole-climbing shoes often only have one area of contact with the columnar structure for a given side of the structure during the climbing process, which can create safety issues if the shoe does not properly grip the underlying structure. Additionally, some pole-climbing shoes, like those shown in India Pat. No. 299,829, utilize complicated climbing mechanisms which coordinate the user's foot position along the frame to the circumference of a spring rope that encircles the tree during climbing. Such climbing mechanisms can be noisy during use and may complicate attachment to the columnar structure.
It is also believed that climbing stick systems have certain drawbacks. As shown for example in U.S. Pat. Nos. 5,040,635, 7,163,082, 9,512,675 and 10,301,873, climbing stick systems typically include a frame with rungs and one or more loops which fasten the frame to the side of the columnar structure. The climbing sticks are typically fixed to the columnar structure in adjacent vertical relation to one another and remain connected for the duration of use. There can likewise be issues with the sticks properly gripping the columnar structure, and the weight of the sticks can limit the number of sticks transported along the structure and thereby limit the maximum height that can be achieved.
As such, it is believed there still exists a need for a climbing apparatus and climbing system that can be used for the quick and stable ascent and descent of varying and various columnar structures, while being easily and quietly transported, used, attached and detached, and which addresses at least some of the foregoing issues.
A climbing apparatus and system are provided for climbing columnar structures such as poles, trees and masts. The system and apparatus are easily and quietly transported, attached, used, and detached from the structure. A single climbing apparatus can be used in conjunction with a tree saddle, rock climbing harness, or similar apparatus, to ascend or descend columnar structures in an incremental fashion. A pair of the climbing apparatus can be used in coordination in a system, to ascend or descend a columnar structure in a simple stepwise fashion. The climbing apparatus or system provides for the stable navigation of columnar structures while being simply and easily attached, and while also enabling the user to easily bypass projections, such as branches, along the columnar structure.
Each climbing apparatus includes an elongated vertical member and at least two stabilizing V-shaped anchors attached along the length of the vertical member. The V-shaped anchors can have a series of serrated teeth to help grip the columnar structure and secure the climbing apparatus during use. A platform, which may be pivotally attached toward the lower end of the vertical member, includes a foot strap to retain the foot of the user. The pivotal attachment of the platform allows for the platform to rotate between a horizontal operating position and a vertical storage position, making the apparatus easy to pack and carry. Also, because the pivotal connection of the platform is in a fixed location along the vertical member, the climbing apparatus is relatively quiet during use. A fastening loop is located around the columnar structure during use and is adjustably and pivotally connected to the vertical member by a bracket located between the two V-shaped anchors. The bracket and fastening loop enhance the secure gripping effect of the V-shaped anchors while allowing for the quick and easy adjustment, attachment, and detachment of the climbing apparatus during the ascent or descent of columnar structures.
When used in a system, one of the climbing apparatus can have a platform attached to the vertical member at a greater distance from the fastening loop bracket than in the other climbing apparatus. This difference facilitates the rapid and easy ascent and descent by the user of the columnar structure by allowing the user to move one of the pairs of climbing apparatus relative to the other without having the fastening loops of each apparatus interfere. This versatility also assists transportation to and from the climbing site by providing a relatively lightweight system, without sacrificing the heights to which the user may achieve. These advantages can similarly be provided in a single climbing apparatus configuration given the relatively lightweight of the coordinating tree saddles, rock climbing harnesses, or similar apparatus used therewith.
During use, after the fastening loops of the system are located around the columnar structure, the user steps upon the respective platforms and is retained to the platforms by the foot straps. The user then alternatingly moves one climbing apparatus along the columnar structure, followed by the other. When ascending or descending the columnar structure, the fastening loop of a given climbing apparatus engages the rear side of the columnar structure. As the user shifts weight to the platform or as the climbing apparatus moves downwardly under its own weight, the fastening loop is pulled taught and pivots relative to the vertical member, which draws the vertical member towards the columnar structure, causing the anchors to firmly grip the columnar structure. This gripping effect caused by the pivoting of the fastening loop increases as more downward force is applied to the climbing apparatus. To climb, the user first shifts their weight to the platform of the leading climbing apparatus. The user can then pull the trailing climbing apparatus away from the columnar structure in a climbing motion and adjust the apparatus upwardly or downwardly as appropriate. The user then shifts weight to the platform of the trailing climbing apparatus causing the trailing climbing apparatus to grip the columnar structure. With the trailing climbing apparatus secured the user may then repeat the lifting and gripping process for the leading climbing apparatus. The alternating movement of the climbing system along the columnar structure by shifting weight to the platform of one apparatus, then lifting or lowering the other apparatus and shifting weight to its platform, can be repeated as needed until the desired height along the columnar structure is achieved. This climbing procedure may likewise be followed using a single climbing apparatus configuration, whereby the user alternately shifts their weight between and incrementally adjusts the location of the climbing apparatus and the coordinating tree saddle, rock climbing harness, or similar apparatus.
If a projection is encountered along the columnar structure, the user can quickly and easily detach the fastening loop of the climbing apparatus and re-attach the loop above or below the projection, while maintaining support on the other apparatus. Whenever the desired height is reached and if one or both platforms are sized appropriately the user may remove their feet from the strap or straps and take a seated position on the platform.
The present disclosure describes an embodiment of a climbing apparatus and system for climbing a columnar structure. The embodiment, parameters, and components described are included as examples and are not to be construed as limiting to the exact form shown. Appropriate modifications of the embodiment may be made, as should be apparent to those skilled in the art, without departing from the spirit or scope of the described embodiment. The embodiment disclosed illustrates a single climbing apparatus, or a climbing system including a pair of climbing apparatus that are used in a stepwise fashion. Individually or in a system, the climbing apparatus are used to climb various columnar structures such as poles, trees, masts, and the like.
Referring initially to
The following climbing apparatus 110 includes an elongated vertical member 115, a platform 120, and a fastening loop 125. A rigid, horizontally extending V-shaped upper anchor 130 and V-shaped lower anchor 135 are connected toward opposite ends of the vertical member 115. The flexible fastening loop 125 is releasably and pivotally connected to the vertical member 115 and configured to encircle a columnar structure 140 during use.
Each of the upper and lower anchors 130 and 135 is preferably formed from a metal strip with serrated teeth 145, and fixed to the vertical member 115, with the upper one of the anchors 130 located toward an upper end of the vertical member 115, and the lower one of the anchors 135 located toward a lower end of the vertical member 115. The anchors 130 and 135 are attached to the vertical member 115 with an upper anchor fastener 150 and a lower anchor fastener 155, which for example, can be a bolt, weld or rivet, or another appropriate device for securely fixing the anchor to the vertical member 115. As indicated above, each of the anchors 130 and 135 has a V-shaped configuration with the arms of the anchor projecting outwardly, away from the vertical member 115 along one side thereof, in order to receive a portion of the columnar structure 140 and increase the lateral stability of a given climbing apparatus 105 or 110 during use.
The fastening loop 125 is adjustably and pivotally attached to the vertical member 115 at a location between the upper and lower anchors 130 and 135. The fastening loop 125 is preferably connected on the upper half of the vertical member 115, for example near the upper anchor 130, by a bracket assembly, indicated generally at 160. The bracket assembly 160 adjustably fixes the fastening loop 125 within a pair of bracket housings 165 and 170, with each distal end of the fastening loop 125 being received within a respective housing. The bracket housings 165 and 170 are pivotally connected by a bracket housing fastener 175 and 180, respectively, such as by a pin or bolt, to a central, V-shaped bracket mount 185, located towards the upper end of the vertical member 115, but below upper anchor fastener 150. The bracket mount 185 is likewise fixedly secured to the vertical member 115 such as by fastener 190, e.g., a bolt, weld or rivet.
The fastening loop 125 is preferably made of a flexible material, for example, an elastomeric polymer or strip of strong fabric or rubber. Referring now to
The left bracket housing 165 can have a pivot pin or bolt 175 projecting outwardly and substantially perpendicularly from the inner-face 220 of the housing 165, while the right bracket housing 170 similarly has a pivot pin or bolt 180 projecting outwardly and substantially perpendicularly from the inner-face 225 of the right bracket housing 170. Referring now also to
Each bracket mount 185 has a pair of rotational limiting pins. Namely, a rotational limiting pin 230 on the left end of the mounting bracket 185 is located so as to limit the rotation of the left bracket housing 165; while a rotational limiting pin 235 on the right end of the mounting bracket 185 is located so as to limit the rotation of the right bracket housing 170. In particular, the pair of rotational limiting pins 230 and 235 are located to allow the bracket housing 170, and hence the fastening loop 125, to rotate from an upwardly angled position (
Referring again to
As shown in
Although the leading climbing apparatus 105 and the following climbing apparatus 110 can be the same, in one embodiment there are certain differences provided between them in order to facilitate the climbing process. Specifically, as seen in
As mentioned above, and as shown in
The user 275 can then raise the climbing apparatus 110 along the columnar structure 140 and pass the fastening loop 125 around the columnar structure 140 and through the other bracket housing 170. Following a similar alignment process as discussed above, the user 275 then passes the fastening loop 125 through the right bracket housing 170 with the bracket housing groove fastener 215 removed. The user 275 then aligns the fastening loop 125 so that the right bracket housing groove fastener 215 can then be inserted in the right bracket housing 170 to engage with the series of grooves 195 of the fastening loop 125, shown in
While securing the second end of the fastening loop 125 using the above process, the user 275 may adjust the length of the fastening loop 125 between the pair of bracket housings 165 and 170. The fastening loop is adjusted so that when the fastening loop 125 is oriented substantially perpendicular to the elongated vertical member 115 as seen in
With the following climbing apparatus 110 attached to the columnar structure 140, the user 275 can then repeat the attachment process for the leading climbing apparatus 105, ensuring that the fastening loop 125 of the leading climbing apparatus 105 is located around the columnar structure 140 above the fastening loop 125 of the following climbing apparatus 110, such that the pair of fastening loops 125 are fastened separately around the columnar structure 140 and are not inter-twined. As should be appreciated, the order of attaching each of the climbing apparatus 105 and 110 can be reversed as desired so that the leading climbing apparatus 105 is first secured to the columnar structure 140 followed then by the following climbing apparatus 110. In any event, with the climbing system 100 attached to the columnar structure 140, as seen in the configuration shown in
As shown in
After the following climbing apparatus 110 is moved vertically, the user 275 may use their hand(s) to hold the fastening loop 125 or bracket housing(s) 165 or 170, in order to manually tilt the far end of the fastening loop 125 upwards, at an angle to the vertical member 115. As the user 275 shifts weight to the following climbing apparatus 110, the fastening loop 125 re-engages the rear side of the columnar structure 140 with enough resistance to completely rotate the fastening loop 125 upwards as shown at
The cycle of shifting weight away from a climbing apparatus, lifting or lowering the leg and moving the climbing apparatus away from and along the columnar structure, engaging the fastening loop at a different height, and shifting weight back to the climbing apparatus to pivot the fastening loop upwardly to produce a gripping effect between the climbing apparatus and the columnar structure, can be repeated alternatively between each climbing apparatus until the desired height is reached.
Likewise, this climbing procedure may be followed by a single climbing apparatus when used in conjunction with e.g., a tree saddle, rock climbing harness, or similar apparatus, except that in those configurations the user alternately shifts their weight between and incrementally adjusts the location of the climbing apparatus and the coordinating tree saddle, rock climbing harness, or similar apparatus.
If a climbing apparatus encounters a branch or other obstacle when ascending or descending the columnar structure, the climbing apparatus may be used to circumvent the obstruction. To do so with the climbing system, the user may first bear their weight on one apparatus so that the non-weight bearing apparatus can safely have one end of its fastening loop disengaged from its bracket housing. Similarly, in single climbing apparatus configurations the user may first bear their weight on the tree saddle, rock climbing harness, or similar apparatus being utilized so that the non-weight bearing apparatus can safely have one end of its fastening loop disengaged from its bracket housing. Regardless of the configuration being used, this temporarily opens the fastening loop so the apparatus can be moved past the obstacle at which point the fastening loop can then be re-engaged within its bracket to close the loop. When the desired height along the columnar structure is reached, the gripping effect simply produced by the rotation of the fastening loop that in turn draws the anchors into the columnar structure, provides a stable platform for the user to operate from (e.g., hunt, bird watch, photograph, etc.). If the platforms are appropriately sized, one or both of the platforms can be used as a temporary seat once the desired height has been reached.
As such, as described above, a climbing apparatus is provided which can be used to quickly and safely ascend and descend columnar structures such as masts, trees, or poles, while being easily and quietly transported, attached, used, and detached. The climbing apparatus can be used in a climbing system wherein a pair of the apparatus are used in a simple stepwise fashion. The climbing apparatus or climbing system provides for the stable navigation of columnar structures while being simply and easily attached, and while also enabling the user to easily bypass projections, such as branches or cross-braces along the columnar structure.
The principles, preferred embodiments, and modes of operation of the present invention have been described in the foregoing specification. The invention, which is intended to be protected herein should not, however, be construed as limited to the particular form described as it is to be illustrative rather than restrictive. Variations and changes may be made by those skilled in the art without departing from the scope and spirit of the invention as set forth in the appended claims.
