1. Field of the Invention
This invention relates to lightweight, portable, rapid setup, hunting ground blinds and methods.
2. Description of Prior Art
There is often a need to conceal oneself when hunting. Hunters often conceal themselves in various hunting ground blinds to avoid being detected by their prey.
In the past, quite complex, heavy structures have been built or constructed for concealment. Hunters have built permanent hunting blinds. Complex blind structures have been carried into the great outdoors.
The following ground blinds or tents are known in the art:
There are also a number of very old patents relating to tents with hinged shafts, such as U.S. Pat. No. 1,502,898, Berg, filed Jan. 12, 1924, or umbrella tents, such as U.S. Pat. No. 1,649,219, Goldberg, filed Mar. 23, 1927. U.S. Pat. No. 74,933, Palmer, issued Feb. 25, 1868, disclosed an inverse umbrella-type frame deployed by a rope external to the enclosure. U.S. Pat. No. 3,794,054, Watts, issued Feb. 26, 1974, disclosed an inverse umbrella tent.
The use of such devices has several disadvantages such as being heavy, bulky, noisy, expensive, and complicated to assemble or use. The frames are relatively weak or fail to adequately tighten the skin. There is a need for a simple, lightweight, compact, portable, rapid setup, hunting ground blind.
In the field of lightweight, portable, outdoor hunting ground blinds, there is a long felt need to have skins extremely tight to avoid detectable movement and noise. Numerous blind designs have attempted to provide the desired skin tightness but have failed without using complex, heavy frames that require significant time and athleticism to set up. Those that are lightweight and fast, such as conventional umbrella designs, fail to put enough force into the frame to provide the desired result. Further, because many blind products have promised, but have failed to deliver, cover skins that remain substantially motionless in windy conditions encountered while hunting, consumers are skeptical. To be successful a product must also stay taut when shaken by potential buyers on the trade show floor or in dealers' show rooms.
The arm muscles (biceps and triceps) of the human body are relatively weak compared to other muscle groups such as the legs, abdomen, back, and shoulders. This is especially true when arms are extended away from the body above the shoulders as is required to deploy conventional umbrella type blinds. Such blinds are set up with the frame expanded in an upright position and the operator either a) pushing up from inside with one hand while pulling a pull cord or shaft down with the other hand, or b) pushing down from outside with one hand while pulling a pull cord up with the other hand while standing beside the structure. For example, see the art cited in U.S. Pat. No. 6,354,316, Chen. Neither of these conventional methods takes advantage of the strongest muscles groups in the body to provide the skin tightening force.
In a horizontal, seated row position, for example as used in Olympic rowing, all of the large muscle groups of the body, including legs, abdomen, back, shoulder, and arms, are used to apply the force through the body between the feet and the hands. A typical outdoorsman can apply up to about 75 pounds of force in the seated row position, with an average of about 40 pounds over the full stroke. A six-foot human body has up to about 45 inches of range of motion in the seated row position (and about up to 65 inches if the arms are extended beyond the head).
Work or energy is measured in foot-pounds. When an operator applies an average of 45 pounds of force over a distance of 3.5 feet (i.e. 42 inches) about 157 foot-pounds of energy is applied. About the same amount of energy could also be stored by applying 57 pounds of force over a distance of 2.75 feet (i.e. 33 inches).
Hunters often have a need to quickly set up a hunting ground blind.
What is needed is a method of setting up a blind where the full muscle strength of the human body from hands to feet can be used to quickly provide the skin tightening force to a lightweight, portable blind. Further, what is needed is a hunting ground blind that can be quickly deployed to provide concealment.
Accordingly, it is an objective of the present invention to provide an easy to use, simple, lightweight, compact, portable, quiet, rapid setup, hunting ground blind, which can additionally be rapidly set up using the large muscle groups of the full human body resulting in tight cover skin. The system includes novel frames, and novel covers, designed specially for hunting.
Objects and Advantages
Accordingly, beside the objects and advantages described above, and in the parent applications, some additional objects and advantages of the present invention are:
In the drawings, closely related figures have the same number but different alphabetic suffixes.
cord—a flexible, and possibly elastic, filament including but not limited to a fiber, thread, string, rope, twine, wire, cable, yarn, thong, tendon, or line.
shaft—a supporting member in construction including but not limited to any solid or hollow, round or rectangular bar, beam, pole, rod, spar, or tube composed of wood, plastic, metal, or composite material.
The present invention comprises an easy to use, simple, lightweight, compact, quick setup hunting ground blind and methods for construction and use. A method of the present invention allows for 360-degree concealment.
The present invention is also directed to various structures and methods for skin tightening for hunting ground blinds. Novel frame structures are used to stretch and thereby tighten the skin of a hunting ground blind. Various solutions to this problem are provided. Various prior attempts to provide lightweight portable blinds with cover skins that remain tight in blustery, hunting conditions have failed because the structure is too weak and/or the set up method does not allow a human operator to apply a sufficient force to the skin tightening mechanism. The present invention includes novel structures and methods that allow the large muscle groups of the full human body to apply a skin stretching force to set up a hunting ground blind with previously unrealized results.
The cover cap 1631 is connected to the skirt 2010 along the corners with corner sections 686 (a-d). The corner sections 686 provide for taut skin.
This embodiment also shows the novel use vertical guylines 1912. Unlike
As discussed above, there is a need for embodiments of hunting ground blinds that can be set up rapidly and standalone in a variety of configurations.
Each half arch cover shafts 1512 comprise half an arch. As shown, for example, in
The pull cord 1536 preferably is attached at one end to a pull handle 1535.
The free ends of each of the half arch cover shafts 1512 each have an end piece means for attaching the fast setup frame 1534 to a quiet cover 1646 (not shown). The end piece means are shown as end pieces 1782.
A separation shaft 943 is connected to the lower plate 946. The half arch cover shafts 1512 (a-d) connect to plate anchors 948 (a-d) respectively on the upper plate 946. The top portion of upper plate 946 also serves as the foot attaching means 1790. A pull cord 1536 runs through the separation shaft 943 in the lower plate 946 and a plate conduit 927 in the upper plate 945.
By pulling the lower plate 946 toward the upper plate 945 using the pull cord 1536, the separation shaft 943 is guided through the bottom of the upper plate 946 into the plate conduit 927 and inserted up to the point where the separation shaft stop 947 meets the bottom of the upper plate 946. The separation shaft tip 944 is rounded to facilitate entry into the plate conduit 927.
The embodiment of the dockless mechanism in
When the blind is initially being spread, the shaft plate 958 connection provides an advantageous lateral force to cause the fast setup frame 1534 to start to open. The tightness and mechanical area of the connection is especially helpful when the fast setup frame 1534 is in the horizontal position as required by the method shown in
The shaft plate 958 and the stretcher shaft 954 connection provides a second advantageous force to the fast setup frame 1534, at point where the separation shaft tip 944 enters the plate conduit 927, to help ensure proper alignment. Further, when the frame is fully set up, it continues to provide stabilizing forces and strength within the fast setup frame 1534 to limit motion and breakage.
The operator 400 pulls most of the pull cord 1536 inside the blind, and tips the blind horizontally to slightly below knee level. The operator 400, for example, stands on a dominate right foot, holds the quiet cover 1646 with the left hand, and kicks the separation shaft tip 944 with the left foot. When the stored energy is released, the blind will automatically jump forward under the left arm of the operator 400 where the now collapsed blind also can be grasped in front of the body with the right hand. The operator 400 can immediately move the blind to a new location. The blind can be collapsed in about 3 seconds.
For long-term transportation, the fast setup frame 1534 can be folded to about half the length of the half arch cover shaft 1512 (a-d) to collapse into a narrow bundle.
The quiet cover 1646 comprises:
The following components of the fast setup frame 1534 (shown in greater detail in
The ground blind is shown with the inverted-T window half open with the open section in a window roll 1672.
In each corner, end piece 1782 is held by a corner pocket 1653. The corner pocket 1653 can be sewn on one or two sides and adjustable with hook and loop fasteners or other fasteners. Alternatively, end pieces 1782 could comprise hooks or slots for attaching to corner loops of cord.
Other cover 1540 embodiments (not shown) could also be used.
The quiet cover 1646 comprises:
The following components of the fast setup frame 1534 (shown in greater detail in
The ground blind is shown with the inverted-T window.
In each corner, end piece 1782 is held by a corner pocket 1653.
An embodiment of a see-through panel 1922 is shown as a fixed shoot-through panel 1642 attached inside each wall covering the area shared by each cover window (such as 1612b).
If a fourth wall does not have a cover window (such as 1612b), some cost could be saved by having no windows or doors, or by having only small windows.
The embodiments shown could also be produced in different sizes. Some could be designed to comfortably hold two people with room for video equipment. Other embodiments could be designed for a single person with a lower profile and less windows. Such embodiments would further reduce weight and cost.
Inverted-T Window
The inverted-T windows allow the top of the blind to be fully opened, or configured in a waterfowl configuration.
Skin Tightening
The novel means of tightening the skin of the present invention provides methods and means for tightening the skin on the sides of a blind cover to reduce movement and flutter in the wind. The means of the present invention include cover shafts that are stretched to cause a constant outward pressure on the sides of the cover. This is done with lower cost, lighter weight, and easier to use structures.
Simple
The present invention is simple to make and use. Each component is easily made. The present invention requires little time to attach and to set up.
The fast setup frame can be quickly set up to provide rapid concealment.
Easy to Use
The present invention is easy to use.
Lightweight
The present invention comprises a few simple parts that can easily be constructed of lightweight materials. Being lightweight is important for those who have to carry gear into the outdoors.
Compact
The embodiments of the hunting ground blind are compact. When collapsed and folded, the frame and cover are rolled together in relatively small bundles. This is advantageous for both storage and carrying.
Portable
The hunting ground blind is lightweight and compact allowing it to be carried long distances into the outdoors and to be used in a variety of locations.
Quiet
The skin tightening features reduce noise from wind movement or flutter.
The novel use of guylines to secure and move windows eliminate the need for zippers or hook and loop fasteners providing for quiet window or opening operation during wildlife observation.
Lower Cost, Longer Reliability
The present invention provides a number of novel features that reduce the complexity and cost of manufacture and that increase the reliability of the parts.
Accordingly, the reader will see that the present invention provides an easy to use, simple, lightweight, compact, portable, quiet, fast setup hunting ground blind.
While the above descriptions contain several specifics these should not be construed as limitations on the scope of the invention, but rather as examples of some of the preferred embodiments thereof. Many other variations are possible. The variations could be used without departing from the scope and spirit of the novel features of the present invention.
Accordingly, the scope of the invention should be determined not by the illustrated embodiments, but by the appended claims and their legal equivalents.
