Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The field of this invention relates generally to human body seating and reclining structures and more particularly to a support structure that is to be included within such a seating and reclining device.




2. Description of the Related Art




Human seating and reclining structures have long been known. Commonly, chairs, sofas and recliners have a flat surface with a cushion that may be placed on the flat surface. It has also been known to construct surfaces out of web strips which are crossed with these web strips being supported by a rigid frame. On the web strips, there will generally be located a cushion.




A common disadvantage of any chair or recliner that has a solid surface is that it lacks air circulation. In hot and humid environments or on any day in which the temperature is elevated, the chair or recliner will cause the user to sweat because there is no air circulation. Also, a solid surface chair or recliner does not follow the contour of the body rather the contour of the human body must conform to the configuration of the chair or recliner. Inherently, this is uncomfortable. It would be far more comfortable if the chair, sofa or recliner deflected to conform to the shape of the body.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to construct a human body support structure that is to be used as a conventional chair, sofa or recliner. The human body support structure of the present invention provides for air circulation and also provides to comfortably support the body of the human by deflecting so the supporting surface conforms to the body of the human. Also, another feature of the present invention is that the human body support structure applies accupressure to the body of the human while the human is sitting or reclining within the chair, sofa or recliner.




A first main embodiment of the present invention utilizes a rigid frame that defines an enclosed space. A plurality of first cords is attached to the frame in a taut manner with these cords extending across the enclosed space. The first cords are located substantially parallel to each other. A plurality of pins are mounted on each first cord with each of the pins being elongated and having a longitudinal center axis. Each first cord passes transversely to its respective pin with the pins being oriented in a spaced-apart arrangement on each of the cords. A plurality of second cords is attached to the frame again in a taut manner. These second cords are also conducted through the pins with the second cords also being parallel to each other. The second cords are oriented substantially perpendicular to the first cords. A plurality of spacers are mounted on both the first cords and the second cords with each spacer being located on only a first cord or a second cord. Each spacer is located between a directly adjacent pair of pins with the spacers functioning to keep the spaced distance between the pins substantially constant. The human body is to be positioned against and supported by the pins with the pins deflecting from their originally established position due to the weight of the human body with the cords permitting this deflection. The longitudinal center axis of each of the pins is located substantially perpendicular to the human body.




A further embodiment of the present invention is where the first main embodiment is modified by the cords being stretchable.




A further embodiment of the present invention is where the first main embodiment is modified by the spacers being defined as being sleeves with either a first cord or a second cord passing through each of the sleeves.




A further embodiment of the present invention is where the first main embodiment is modified by the upper surface of each of the pins being rounded.




A further embodiment of the present invention is where the first main embodiment is modified by there being included a third set of cords which are located parallel to but spaced from the first cords.




A further embodiment of the present invention is where the first main embodiment is modified by there being a series of fourth cords which are also mounted on the pins with the fourth cords being located parallel to the second cords but spaced therefrom.




A second main embodiment of the present invention defines a human body support structure which comprises a rigid frame which defines an enclosed space. Mounted within the enclosed space and mounted on the frame is a crossed series of cords having thereon mounted a plurality of pins which are oriented in a parallel relationship. The upper surface of the pins provides a supporting surface for the body of the human.




A further embodiment of the present invention is where the second main embodiment is modified by the cords being stretchable.




A further embodiment of the present invention is where the second main embodiment is modified by there being spacers mounted on each cord with there being a separate spacer located between each directly adjacent pair of pins.




A further embodiment of the present invention is where the second main embodiment is modified by the upper end of the pins being rounded which is the surface of the pins that comes in direct contact with the body of the human user.

DETAILED DESCRIPTION OF THE INVENTION




Referring particularly to the drawings, there is shown in

FIG. 1

a chair


10


. The chair


10


has a seat


12


and a back


14


. A left side


16


and a right side


18


are located on opposite sides of the seat


12


and the back


14


and connect together seat frame


20


and back frame


22


. It can be seen by observing

FIG. 1

that the back


14


is located substantially perpendicular to the seat


12


. Although a chair


10


is shown in

FIG. 1

, it is to be understood that the subject matter of this invention could be incorporated in other types of human support structures, such as recliners, ottomans, sofas, chaise lounges, hammocks and any other type of structure that is designed for seating or reclining of a human. Typically, the structure of the present invention will be particularly useful in the construction of outdoor furniture, home furniture and office furniture. The seat frame


20


constitutes a rigid structure surrounding an enclosed space


24


. A similar enclosed space


24


is formed by the back frame


22


. Included within each enclosed space


24


is the human body support structure


26


of this invention.




Mounted between the members of the seat frame


20


or the back frame


22


are a series of first cords


28


. The first cords


28


are to be slightly stretchable, small in diameter, maybe no more than an eighth of an inch in diameter, and resemble a string. Each of the cords


28


is mounted in a taut relationship on their respective seat frame


20


or back frame


22


. Each of the first cords


28


are located evenly spaced apart. The number of the first cords


28


can be increased or decreased according to what is desired. It happens to be that the number selected is twelve in number. Each first cord


28


passes through a hole formed in a pin


30


. There are actually twelve in number of the pins


30


mounted on the each first cord


28


, and since there are eighteen in number of the first cords


28


located between the sides


16


and


18


, that means there will be a total number of two-hundred and sixteen pins


30


. There will be two-hundred and sixteen of the pins


30


located in both the seat


12


and the back


14


. However, in a recliner, sofa, hammock or chaise lounge, it is understood that there will almost assuredly be a greater number of pins


30


.




Between the sides


16


and


18


, there are mounted a plurality of second cords


32


. The second cords


32


are all identical and again the same as the first cords


28


. The second cords


32


are located in a perpendicularly oriented relationship relative to the first cords


28


. The second cords


32


also pass through a series of the pins


30


with it being understood that each cord


32


will pass through eighteen in number of the pins


30


while each cord


28


only passes through twelve in number of the pins


30


within the embodiment of the invention shown in FIG.


1


.




There are also eighteen in number of third cords


34


. The third cords


34


are located parallel to the first cords


28


. Each third cord


34


is spaced about one and one-quarter inch from the first cord


28


. Each third cord


34


also passes through a hole in each of the pins


30


with it being understood that each third cord


34


will be conducted through twelve in number of the pins


30


.




Also mounted through a hole in each of the pins


30


is a fourth cord


36


with the fourth cords


36


also being identical in construction to the first cords


28


. The fourth cords


36


are located parallel to each other and are located parallel to the second cords


32


and are spaced about one and one-quarter inch from each second cord


32


. Each of the fourth cords


36


will also be conducted through eighteen in number of the pins


30


.




Each of the pins


30


has a rounded upper end


38


. When there is no human resting against the structure


26


, the pins


30


are in the position shown in

FIG. 2

with the rounded upper end


38


all being located on a plane


40


. However, when the human places his or her body against the rounded upper ends


38


, the entire series of pins


30


will deflect, as shown in

FIG. 3

, with the human body being defined as line


42


. The deflection of the pins


30


will be permitted by the stretching of the cords


28


,


32


,


34


and


36


. The spacing between the pins


30


is maintained essentially constant by the using of spacers


44


. Each spacer


44


constitutes a sleeve with each of the cords


28


,


32


,


34


and


36


being conducted through a series of the spacers


44


with there being a spacer


44


between each directly adjacent pair of pins


30


. The function of the spacers


44


is to keep the pins


30


spaced about three-eighths of an inch to one-half of an inch apart. The spacers


44


are shown to be a separate part from the pins


30


. However, it is considered to be within the scope of this invention that the spacers


44


could actually be incorporated to be part of the pins


30


.




It is to be understood that when the weight of the human body is placed against the rounded upper ends


38


of the pins


30


, as is shown in

FIG. 3

, the pins


30


do not deflect. Each pin


30


remains the same size. The pins


30


deflect within the structure


26


which is permitted by the stretchiness of the cords


28


,


32


,


34


, and


36


.




It is to be noted that when the weight of the human body is placed against the rounded upper ends


38


, as is shown in

FIG. 3

, the pins


30


will actually pivot so that the longitudinal center axis


46


of each pin


30


will be located substantially perpendicular to the body surface represented by line


42


. This perpendicular arrangement is desired as this is most comfortable to the user. Also, it is therapeutic in that the pins


30


function to apply accupressure to the user which may help to relieve soreness in muscles.




Because each pin


30


is supported on four different cords,


28


,


32


,


34


and


36


, each of the pins


30


will function to twist as weight is applied to the plane


40


so as to maintain a perpendicular relationship with respect to the surface


42


. Without the use of the four different cords, this twisting of each of the pins


30


would be difficult to accomplish. The length of each of the spacers


44


is deemed to be a matter of choice. However, in most instances the spacers


44


will be between one-fourth and one-half inch in length.




Referring particularly to

FIGS. 5 and 6

, there is shown a modified form of constructional arrangement between the pins


48


and the spacers


50


. Each pin


48


has a plurality of bosses


52


which protrude from the sidewall of its respective pin


48


. Each boss


52


is located at a hole


54


that is formed within the pin


48


. It is to be understood that each pin


48


will have eight in number of the bosses


52


. Each spacer


50


has a through hole


56


. At the end of each spacer


50


forms an annular chamfered edge


58


. Each chamfered edge


58


is to matingly engage with an annular inclined surface


60


formed interiorly of each boss


52


. The structural arrangement between the pins and spacers in

FIGS. 5-6

versus

FIGS. 1-4

is that the pins


48


and spacers


50


are interconnected by the chamfered edges


58


and their respective annular inclined surfaces


60


, wherein

FIGS. 1-4

there is no such connection but just an abutting relationship. In

FIGS. 5-6

, there still is used the first cords


28


, second cords


32


, third cords


34


and fourth cords


36


in the same arrangement as was previously discussed in

FIGS. 1-4

.




Each of the pins


48


has a smoothly contoured tip


62


which is a little bit more flat than in

FIGS. 1-4

. The tips


62


provide a slightly greater flat surface area of contact than the rounded upper ends


38


which may prove to be more comfortable to a user.
