FIELD OF THE INVENTION
The present invention relates generally to the field of ladders and devices for ladders. More particularly, the present invention relates to a protective ladder guard for hunting stands to prevent unauthorized persons from ascending the ladder to reach the hunting stand platform in the owner's absence.
BACKGROUND OF THE INVENTION
The use of ladder hunting stands, which provide an elevated platform above the ground while hunting wild game animals, is well documented. There are numerous commercially available ladder tree stands, tri-pod stands, elevated modular stands, automated game feeder systems and the like, which provide access to an elevated platform or enclosure relative to the ground, using an integral ladder for climbing. While tree stand manufacturers produce a wide variety of ladder stands, they do not provide devices designed to prevent unauthorized persons from climbing the ladder to reach the hunting platform in the owner's absence. Such a device would prevent trespassing, the poaching of wild game animals, and the theft or vandalism of the tree stand or the tree stand accessories. As a result, demand exists for a simple, portable, convenient, inexpensive protective device, designed to prevent unauthorized persons from ascending the ladder to reach a hunting platform above.
The unauthorized climbing of ladder hunting stands is a problem many hunters face. This unwelcome behavior may often result in the theft of the hunting stand, hunting stand accessories or other valuable personal property, and facilitates the poaching of wild game animals. Many tri-pod, elevated modular stands and automated game feeder systems have further refinements of value also posing a risk of theft or vandalism. The aftermath of such trespassing activity continues to be a source of great frustration to honest and ethical hunters.
Ladder guards, which deter unauthorized ladder climbing are well known. U.S. Pat. No. 7,793,759 to Aiken, U.S. Pat. No. 7,717,231 to Horton, U.S. Pat. No. 5,441,126 to Orrick, U.S. Pat. No. 4,126,206 to Becnel, and U.S. Pat. No. 3,968,857 to Bryan are examples representing endeavors to block access to a plurality of rungs to prevent unauthorized climbing of ladders. While such devices and methods suit their intended purpose well for use with commercial ladders, step ladders, swimming pool ladders and the like, or for ladders of a type permanently secured to tall buildings, radio towers, storage tanks and the like, they are not satisfactory for use with modern ladder hunting stands, and do not effectively solve many specific problems faced by hunters.
One solution, the Vital-Security™ slide/lock by Vital Zone™, requires permanent structural modifications be made to the lower bottom two sections from the original tree stand ladder, which incorporate a set of sleeves and hinges now integral to the intersecting ladder columns, locking pin mechanisms and padlocks. In use, both hinge mechanisms are first unlocked and then the protective sleeves are raised to allow the bottom section of the ladder to be folded upward to connect with a receiver housing integral to the next uppermost section of the ladder, allowing the hinge mechanism to be secured using a locking pin, and then be finally secured using a padlock. To lower the ladder section and return it to ground level, the process is reversed, thus allowing access to the ladder.
Another solution, manufactured by Primal Vantage™, requires permanent replacement of the lower bottom section from the original tree stand ladder, with a new section of ladder, having a removable square framed insert having two rungs welded horizontally inside the frame, requiring four long threaded bolts to be passed through the column from the outside and secured into four threaded receiver holes integral to the square framed insert. To prevent climbing the ladder, the four long bolts must be removed and retained for later use, the insert section must be removed, and transported to and from the hunting stand each time. The process is reversed to reinstall the section, thereby allowing access to the ladder.
Many hunters reject such solutions because of the many potential safety problems and mechanical difficulties encountered while attempting to retrofit a ladder hunting stand that has already been installed. In the case of ladder tree stands, the ladder supplied by the manufacturer is an integral component of the product's design, thus any post installation modifications could affect the tree stand's structural integrity. Once connected and installed, each section of the ladder serves to support the next section sequentially supporting the ladder structure and the tree stand platform. Removing a section of the ladder is risky and difficult post installation due to the difficulty of separating the reverse interconnecting sections, and compounded by the total combined weight of downward forces being applied by the mass of the ladder and tree stand platform. Any attempt to remove the ladder or to rotate a section of the ladder out of the way could negate the structural support element designed for the ladder thus affecting platform sturdiness, allowing other ladder sections to separate or allowing the hunting platform itself to shift position on the tree. Undermining the safety and stability of the tree stand platform in this manner could lead to a potentially unsafe or dangerous situation, especially if the ladder or platform becomes loosened or dislodged from the tree while in use. Should an unfortunate accident or injury occur, the hunter also bears risk of liability should an insurance claim ensue. Potential remedies could also be found limited simply because structural modifications were made to the tree stand after purchase.
Another problem encountered is that these solutions require several time consuming, intricate, multi-step tasks, which must be completed with a certain degree of precision, and which must be performed safely every time the hunter enters or leaves the area. In addition, it is highly desirable to occupy the hunting stand well before sunrise and depart the area after sunset, thereby increasing the difficulty in performance of these tasks in darkness, thus reducing the safety margin required to perform such tasks. In addition, maintaining total quiet of the surrounding area is also an essential element for successful game hunting. It is doubtful these tasks can be accomplished consistently, quickly, and safely in the dark, without making unwanted metallic noises, which undoubtedly will disturb the wild game animals in the surrounding area. In the case of tri-pod hunting stands or elevated modular houses, the problem encountered is that attempting to retrofit the ladder is likely not a practical solution, because the entire ladder is typically welded to and centered over a main support beam of the tri-pod frame or modular structure. Thus, the presence and positioning of the support beam prevents structural modifications and interferes with retrofitting activity.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for preventing access to ladder hunting stands, which solves the aforementioned problems, protects the private property of hunters and prevents poaching of wild game animals.
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of ladder guards.
Aspects of the present invention relate to a hunting ladder guard for hunting ladder stands, tri-pod stands, modular hunting stands and the like.
In related aspects, the hunting ladder guard provides a simple yet effective protective ladder guard device to prevent unauthorized persons from ascending the ladder to reach the hunting stand platform in the owner's absence, thereby preventing trespassing, theft, vandalism and poaching of wild game animals.
In related aspects, the hunting ladder guard is designed to secure most hunting ladder stands and tri-pod ladder stand designs.
In an aspect, a hunting ladder guard, can include:
- a. a ladder guard plate, further including
- i. a plate hook, which is connected to an upper end of the ladder guard plate; is configured as an inward protruding hook that attaches on to an upper rung of a hunting ladder;
- ii. two or more bracket apertures; and
- b. a bracket;
- such that a lower end of the ladder guard can be attached to a lower rung, and the bracket inserted through two consecutive bracket apertures, which are positioned such that an upper leg of the bracket reaches behind and over the lower rung, and a lower leg of the bracket reaches behind and under the lower rung, such that a padlock can be inserted through padlock apertures in the upper and lower legs of the bracket, thereby locking the ladder guard plate in place on the hunting ladder.
In another aspect, a ladder guard to prevent access to a ladder, can include:
- a. a ladder guard plate, further including:
- i. a plate hook, which can be connected to an upper end of the ladder guard plate, such that the plate hook is configured as an inward protruding hook that attaches to a rung of the ladder; and
- ii. at least one plate aperture;
- b. at least one bolt;
- c. a stabilizer bracket, further including:
- i. a connector plate, further including:
- at least one connector plate aperture;
- wherein the connector plate can be connected to a lower end of the ladder guard plate with the at least one bolt, which can be bolted in place through the at least one plate aperture and the at least one connector plate aperture;
- ii. an upper flange portion, which is connected to the connector plate;
- iii. a lower flange portion, which is connected to the connector plate; and
- iv. an upper flange extension, further including:
- an upper flange extension aperture;
- wherein the upper flange extension is connected to the upper flange portion; and
- v. a lower flange extension, further comprising:
- a lower flange extension aperture,
- wherein the lower flange extension is connected to the lower flange portion;
- wherein the upper end of the ladder guard plate is configured to be attached to an upper rung of the ladder using the plate hook; and
- the lower end of the ladder guard plate is configured to be attached to a lower rung of the ladder, such that the upper flange portion is above the lower rung and the lower flange portion is below the lower rung;
- such that the upper and lower flange extensions extend behind the lower rung;
- such that the stabilizer bracket is configured to allow a padlock to be inserted through the upper flange extension aperture and the lower flange extension aperture, thereby locking the stabilizer bracket in place around the lower rung, and thereby locking the lower end of the ladder guard in place, attached to the lower rung.
In related aspects, the hunting ladder guard can be designed to be inexpensive, lightweight, sturdy, weatherproof, convenient, easy to transport, and easy to use. In further related aspects, it can reduce risk of potential serious injury by not requiring a hunter to retro fit, disassemble or reassemble the ladder stand sections because the ladder or hunting platform is never retracted, replaced or moved, and thus does not undermine the hunting stand structural integrity.
In other related aspects, the hunting ladder guard requires no special tools, or installation or removal of nuts and bolts, and complex repetitive installation and removal tasks are reduced to a minimum.
In other related aspects, the hunting ladder guard allows hunters to quickly and quietly unlock the device with a minimum of effort, while standing on the ground, while working in darkness and without disturbing nearby game animals, place the accessory on the ground while hunting, and quickly, easily and quietly reinstall and secure the device before departing the area. Further, in related aspects, because many hunting stands are often located in extremely remote locations, the hunting ladder guard can provide year round protection, should a hunter decide to leave the hunting stand in place during the off-season as a proactive measure or be used to address potential liability concerns, especially when the hunting stand is located on private property.
There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.
