The present invention relates to treestands. People, especially hunters, wish to be able to observe and monitor wildlife without interfering in the wildlife's behavior. For hunters this means allowing the wildlife, i.e., game animals, to venture close enough to the hunter so that the hunter can target the animal without the animal detecting the hunter and leaving the area. For others, for example photographers or bird watchers, this means remaining hidden so that the wildlife behaves in its natural manner.
Treestands are used by people to remain relatively unnoticed by wildlife. Treestands are used to position a person above the ground and out of an animal's line of sight and smell. However, many of the treestands available today can thwart the goals of the hunter or wildlife observer. They tend to be heavy, making them both difficult to transport and install in a tree. Further, when used, they can contribute to the user being detected by an animal by contributing to an unacceptably high noise level. This noise level is caused, in part at least, by the treestand standing platform being composed substantially of metal.
What is needed in the art are treestands that are easier to transport and that do not cause unnecessary noise when used.
The present invention provides treestands that solve the problems associated with prior art treestands in that they are lighter and in that they minimize the generation of noise when used. The treestands of the present invention are novel and non-obvious over the prior art.
In one aspect, the treestands of the present invention comprise a standing platform. The standing platform of the treestand of the present invention comprises a support platform for supporting a user, the support platform comprising a resilient and flexible material (e.g., a fabric) that is under tension. The tension can be provided by any means but in a preferred embodiment, the tension is provided by cables or cords (collectively referred to herein as “cord material”) that are laced through the edge of the resilient and flexible material, around a frame, and drawn tight. The tension on the resilient and flexible material is high enough that the fabric provides a firm platform for standing on. The resilient and flexible material may be removably attached to the frame.
In this regard, the standing platform of the treestand of the present invention comprises a support platform for supporting a user and a means for attaching the standing platform to a tree. The standing platform comprises a frame, the frame being comprised of, for example, a light weight material such as one or more of aluminum, carbon fiber, titanium or wood. The frame can be of any suitable shape. In one aspect of the invention, the frame is essentially rectangular shaped with rounded corners. When rectangular, the frame is comprised of a front frame member, a rear frame member and a first and second side frame members, collectively referred to herein as frame members. The frame may also be considered rectangular with one or more of the front, rear or side frame members bowed or curved in the plane of the standing platform. In one embodiment, the standing platform specifically excludes non-flexible members positioned between and/or attached to the frame members in the plane of the frame and between the frame members.
The support platform may comprise the resilient and flexible material of the present invention, which may be suspended between the frame members of the standing platform with a plurality of attachment points. In one embodiment, the attachment points comprise one or more cords laced through the edge of the resilient and flexible material and around the frame members, the cord material being passed alternately from the frame members and the flexible material at the attachment points. In another embodiment, the resilient and flexible material is attached by loop and hook fastener. In another embodiment, the resilient and flexible material may be extended over the frame members thereby providing for opposite ends of the flexible and resilient material to be opposingly oriented to each other under the plane of the support platform. In this aspect of the invention, the resilient and flexible material is laced with one or more cords through the edge of the resilient and flexible material under the plane of the standing platform. The cord may be threaded through grommets on the resilient and flexible material.
In some embodiments, the resilient and flexible material of the support platform may comprise areas of reduced flexibility (but still flexible), such as flexible stiffening members, overlapping layers of fabric or areas of thicker fabric. In one embodiment, the support platform specifically excludes non-flexible members. In another embodiment, support platform specifically excludes non-flexible members that attach to or touch at least one frame member. In the context of the present invention, any grommets and area of reduced flexibility used with the resilient and flexible material do not constitute non-flexible support platform members.
In one embodiment, the standing platform and the support platform of the present invention collectively can support a user weighing up to 200 lbs., 250 lbs., 300 lbs. or 350 lbs.
In one embodiment of the present invention, the support platform may further comprise a reversibly removable cover for the standing platform that covers or substantially covers the frame, the resilient and flexible material and the cord(s). The cover may be used, for example, to keep the frame and resilient and flexible material clean and/or to provide camouflaging. The cover may be padded or unpadded. The cover may be washable.
The treestand of the present invention may also comprise a seating platform located above the standing platform. The seating platform may be constructed in the same manner as the standing platform, if desired, with a seat and, optionally, back support, one or both made of resilient and flexible material placed under tension. This design will provide for a further reduction in weight and provide for a quieter treestand. However, since the user will not be standing or stepping on the seating platform, the need for noise reduction is not as great as with the standing platform. In another embodiment, the seating platform may be a comfortable hanging seat.
The treestand of the present invention further comprises a means for attaching the treestand to a tree. The present invention is not limited by the means used for attaching the treestand to a tree. Many such methods and devices are known to one of ordinary skill in the art and are incorporated herein. For example, such means include, but are not limited to, one or more of clamps, straps and spikes (e.g., points or barbs) and one or more suitable tensioning devices such as ratchets and turnbuckles, as are known in the art. The treestand of the present invention may have one attachment device or a separate attachment device for each of the standing platform and seating platform. Further, stabilizers such as spikes may be used to stabilize the platform to the tree.
In yet another aspect of the treestand of the present invention, the treestand may be collapsible or foldable for ease of transport or storage. In yet another aspect of the present invention, the seating platform may be attached to, reversibly removable from or separate from the standing platform.
The invention will now be described in further detail and as exemplified by the figures.
Various embodiments of the invention will now be explained in greater detail. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention as claimed. Any discussion of certain embodiments or features serves to illustrate certain exemplary aspects of the invention. The invention is not limited to the embodiments specifically discussed herein.
Unless otherwise indicated, all numbers such as those expressing temperatures, weight percent, concentrations, time periods, dimensions, and values for certain parameters used in the specification and claims are to be understood as being modified in all instances by the term “about,” unless clearly stated otherwise. It should also be understood that the precise numerical values and ranges used in the specification and claims form additional embodiments of the invention.
The present invention may be understood more readily by reference to the following detailed description of the invention taken in connection with the accompanying drawing figures, which form a part of this disclosure. It is to be understood that this invention is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed invention. Accordingly, unless explicitly stated otherwise, the descriptions relate to one or more embodiments and should not be construed to limit the embodiments as a whole. This is true regardless of whether or not the disclosure states that a feature is related to “a,” “the,” “one,” “one or more,” “some,” or “various” embodiments. Instead, the proper scope of the embodiments is defined by the appended claims. Further, stating that a feature may exist indicates that the feature may exist in one or more embodiments.
Also, as used in the specification including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value and all values between, regardless as to if they have been explicitly identified. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment.
In this disclosure, the terms “include,” “including,” “comprise,” “comprising,” “contain,” “containing,” “have,” and “having” when used after a device, set or a system, mean an open inclusion and do not exclude addition of other, non-enumerated, members to the set or to the system. Further, unless stated otherwise or deducted otherwise from the context, the conjunction “or,” if used, is not exclusive, but is instead inclusive to mean and/or. Moreover, if these terms are used, a subset of a set may include one or more than one, up to and including all members of the set.
The phrase “consisting of” excludes any element, step or ingredient not specified in the claim. The phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps and materials or steps that do not materially affect the basic and novel characteristics of the claimed invention. It is clear from this specification which elements do and do not materially affect the basic and novel characteristics of the claimed invention. Further, any elements recited in a dependent claim, even though further limiting, are not considered to be essential to the elements recited in the identified independent claim. The present disclosure contemplates embodiments of the invention compositions and methods corresponding to the scope of each of these phrases. Thus, a composition or method comprising recited elements or steps contemplates particular embodiments in which the composition or method consists essentially of or consists of those elements or steps.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods and materials are now described.
The present invention is for treestands for wildlife observation that reduce noise generation when used and are lighter thereby easing transport and installation, as is evident from the description.
