GROUND BASED PORTABLE SEAT
A ground based portable seat which is capable of elevating the user up and off the ground and provides for a variable seating position independently or in combination with an object on terrain of varying slopes and undulating surfaces. A frame structure includes first and second generally U-shaped frame members pivotally attached to each other at their open ends and with a sling member suspended between the distal lateral closed ends. The sling member is shorter than a length that allows the pivotal connections to be opened to a pivot angle of 180 degrees magnitude. Placing the two pivotal connections on the ground for use of the seat, makes two point contact with the ground as a base. A third, stabilizing point of ground contact is provided by the user's foot.
This application claims the benefit of U.S. Provisional Patent Application No. 60/779,976, filed Mar. 7, 2006 by Gausman.
TECHNICAL FIELD OF THE INVENTIONThe present invention relates generally to a ground based portable seat. In particular, the invention relates to a ground based portable seat that is adapted for use independently or in combination with an object. In particular, the invention relates to a ground based portable seat that is adapted for use independently or in combination with an object on terrain of varying profile and slope.
BACKGROUND OF INVENTIONIn sporting activities such as hunting, bird watching, field studies or the like it is desirable for a person to find a location to sit and observe their surroundings. While observing the surroundings it is important to blend in with the surroundings and not stand out. In particular, the outline or silhouette of the body should be broken up or minimized. One way this is achieved is by standing or sitting in close proximal relation to an object such as a tree, rock, fence post, hay bale or the like. Specific to the activity of hunting, this close proximal relation to an object provides for the additional safety benefit of protecting the hunter from an errant shot or a shot at unidentified game from behind.
Specific to the activity of hunting, there are essentially two main observation perspectives, namely elevated structures such as a tree stand or from the ground. In the past, a variety of types of tree stands have been available to and used by hunters. Hunters may choose not to utilize such tree stands for a number of reasons, including the hunter's physical condition, the cumbersome weight of tree stands, the hunter's fear of heights, the potential for accidental falls, or the hunter's age. Ground-based hunters are faced with problems such as finding a suitable place to sit and the weight of ground based seats. Although portable ground-based seats exist, none are capable of providing the hunter with the ability to sit comfortably in close proximal relationship to an object such as a tree, rock, fence post, wall or the like due to the fixed relationship between the seat surface and the ground. Further, in the past many portable ground-based seats have been unnecessarily heavy and/or otherwise difficult to carry and required separate support structures to maintain the hunter in a fixed seated position.
In particular to the close proximal relationship to a tree the variability of the “root radius” has not been overcome. Root radius is defined as the geometry created by the relationship of ground and a tree that is adjacent and contiguous to where the two meet. This geometry contains the ground segment, the tree segment and the radius of the root there between. The combinations that result are numerous and range from acute to obtuse angles between the ground and tree segments with large and small root radius. Additionally, the ground located in the root radius region is capable of being undulated and not conducive to a line contact as required by prior seats for stability.
Prior seats required a separate structural member attached to both the seat portion and back portion to prevent rotation of the back portion away from the seat portion. This structure limited the seat to a single angle between the seat portion and back portion and thus limited the ability of the user to adjust their position.
Further to the activity of hunting is the transportation of gear into the field. In particular, on route to the final destination it is advantageous to carry gear such as additional clothing items that are to be worn once arriving at the final destination. This enables the hunter to maintain a lower body temperature and perspire less. Once at the final destination the gear that was carried is dry and free of perspiration.
Further to the activity of hunting is the safe transportation of game out of the field. In particular, game can be a turkey, coyote, or similar sized harvested game animal.
Separate to the act of hunting are activities where sitting on the ground or other surface with or without the aid of a support structure. In particular these activities can take place outdoors and include such spectator events as watching a concert, baseball game, soccer game, and the like. Additionally these activities can take place indoors as well and include such events as watching TV, playing board games, and the like.
Accordingly, it is desirable and advantageous to provide a portable ground-based seat which is adapted for use in close proximal relation to an object. It also is desirable and advantageous to provide a portable ground-based seat which is lightweight and easily carried.
An object of the present invention is to provide a portable ground-based seat which may be utilized in close proximal relation to an object which may itself be on terrain that is flat or steep sloped, as well as terrains having slopes there between.
Another objective of the invention is to provide a portable ground-based seat which may be utilized independent of an object on substantially flat terrain.
Another object of the present invention is to provide a portable ground-based seat which includes a sling structure and support means for enabling the user to adjust their position in the seat.
Yet another object of the present invention is to provide a portable ground-based seat which is convenient to carry and can be set up in a short amount of time.
Yet another object of the present invention is to provide a portable ground-based seat which is convenient to carry and can be used to haul other items such as game or gear.
SUMMARY OF THE INVENTIONThe present invention contemplates an apparatus that provides for a comfortable ground based seat for use in close proximal relation to a stationary object, is light weight, sets up quickly and can be used as a means for hauling gear and game.
The invention provides in one aspect a ground-based seat.

BRIEF DESCRIPTION OF THE DRAWINGS
While the prior art has contemplated in some degree a ground based portable seat, said prior art known to the inventor has been limited in achieving the optimum seating position, contains additional and un-needed structure or is limited in where it can be used.
For example, U.S. Pat. No. 5,839,783 issued to Black, U.S. Pat. No. 1,625,106 issued to Sullivan, U.S. Pat. No. 1,963,708 issued to Marvin and U.S. Pat. No. 5,385,390 issued to Freeman all contemplate a portable ground based seat that places the occupant in a fixed relation to the ground, places the seat in line contact with the ground and includes additional structure not required in the present invention. The additional structure further limits the seating position of the user.
Further, another example of the prior art, depicted in
The long frame member 102 length is greater than or equal to the short frame member 104 length. In the instance the long frame member 102 is greater than the short frame member 104 the long frame member 102 is roughly the length of the torso on an average adult male while the short frame member 104 is roughly the length of thigh of an adult male. In the instance the long frame member 102 is equal in length to the short frame member 104 the long and short frame members 102 and 104 are roughly the length of thigh of an adult male. Long and short frame members 102 and 104 are preferably metallic with the metals of choice being aluminum for its lightweight or of galvanized steel such as electrical conduit for greater strength although heavier than the aluminum. As well, the preferred shape of first and second frame members is tubular, however, it can be appreciated that a variety of materials and shapes are possible in order to achieve the necessary support.
Supported by the frame members is a sling member 108. The sling member 108 is comprised of a sling lower region 110, a sling upper region 112 and a sling central region 114. The sling lower region 110 attaches to the short frame lateral end region 104c. The sling upper region 112 attaches to the long frame lateral end region 102c. The sling 108 is made of a flexible material such as fabric (e.g. canvas, cordura, cotton duck, nylon). The invention is functional and usable in this condition. The additional components now described enhance the practicality and durability of the invention.
Attached to the sling upper region 112 is an optional upper support strap 116. Optional upper support strap 116 attaches to the sling upper region 112 by sewing, gluing or the like. Optional upper support strap 116 is at its ends attached to the long frame member generally parallel sections 102a and 102b. Optional upper support strap 116 provides for centering the sling upper region 112, as well as supporting the long frame member generally parallel sections 102a and 102b by preventing outward displacement (spreading apart) when the user is seated.
Attached to the sling central region 114 is an optional central support strap 120. Optional central support strap 120 attaches to the sling member central region 114 by sewing, gluing or the like. Optional central support strap 120 is at its ends attached to the long frame member generally parallel sections 102a and 102b. Optional central support strap 120 provides for centering the sling central region 114, as well as supporting the long frame member generally parallel sections 102a and 102b by preventing outward displacement (spreading apart) when the user is seated.
Attached to the sling lower region 110 is an optional lower support strap 118. Optional lower support strap 118 attaches to the sling lower region 110 by sewing, gluing or the like. Optional lower support strap 118 is at its ends attached to the short frame member parallel sections 104a and 104b. Optional lower support strap 118 provides for centering the sling lower region 110, as well as supporting short frame member parallel sections 104a and 104b preventing outward displacement (spreading apart) when the user is seated.
It can be appreciated by one skilled in the art that the practical aspects of optional support straps 116, 118 and 120 are to keep the sling 108 centered on the long and short frame members 102 and 104, as well as supporting frame member generally parallel sections 102a and 102b, 104a and 104b by preventing outward displacement (spreading apart) when the user is seated. Of course, if a support strap 116, 118, 120 is rigid, then it would also prevent inward displacement of the frame member generally parallel sections 102a and 102b, 104a and 104b. As a result of using one or more flexible or rigid support straps 116, 118, 120, a heavier load can be supported by a light weight seat. As such, integrating these straps directly into the sling 108 is anticipated.
Located between hinges 106 is an optional ground strap 122. Optional ground strap 122 provides for the practical aspect of preventing the open ends 102′, 104′ at the pivotal connections 106 from being driven into soft ground under the weight of the user. All straps 116, 118, 120 and 122 are preferably made of a flexible material (e.g. nylon webbing, rope, canvas).
Located and affixed to sling upper region 112 is a transport strap 124. Transport strap 124 is attached at one end to the sling upper region 112 by sewing, gluing or the like. Transport strap 124 is attached at the opposite end to hinges 106. The practical aspects of this transport strap are to carry the seat and game or gear as appropriate.
