Description
Background of the Invention
1. Field of the Invention
The present invention relates to portable folding furniture and, more particularly, to a portable folding lounger having a strong elastic breathable fitted fabric conver and being structured to comfortably support a tall and robust person.
2. Description of the Prior Art
A seat or chair structure that supports some type of pad or covering has been appreciated in prior art. Such a pad or covering is often of a canvas or a synthetic material which may become soiled and after exposure to the sun may fade or become hot. A prior art lounger having a canvas covering is described, for example, in U.S. Pat. No. 4,921,301 issued May 1, 1990 to R. Jalaine Haynes. Another lounger having a canvas or plastic covering is shown in U.S. Pat. No. 4,892,353 issued Jan. 9, 1990 to Dan J. Goddard.
Methods of enhancing the comfort of a longer are known. It is common practice to drape a towel or blanket over the chair for comfort and convenience of the user. The towel or blanket absorbs tanning oils and lotions and protects the user from the hot surface of the covering. The disadvantage of the towel or blanket is that the towel or blanket is subject to shifting. Accordingly, the user must continually readjust or reposition the same to make certain that it covers the surface beneath the user. A mat would be an alternative to a towel or blanket. For instance, U.S. Pat. No. 4,979,735 issued Dec. 25, 1990 to Robert L. Nathans et al. discloses a mat positioned upon a lounge chair. The mat is comprised of a plurality of parallel channels being fabricated of a flexible vinyl plastic. A continuous flow of water is circulated through each channel to facilitate cooling a person using the lounge chair.
Another lounger which provides a cooling effect is described in U.S. Pat. No. 4,141,585 issued Feb. 27, 1979 to Wynona Blackman. Blackman teaches a folding cooling lounge chair having a plurality of vented chambers, each adapted to receive a coolant therein. A fan is employed to create air flow through the chambers, forcing air through the vents to cool a person off.
A variety of lounge chairs have been described and various methods have been devised to keep the user of lounge chairs cool, however, a lounge chair which is covered with a fabric having a composition with a low coefficient of absorption would absorb less radiant heat when exposed to the sunlight and, in turn, remain cooler and provide greater comfort for the user. Moreover, a woven fabric having a large number infinitesimal interstices would be exceptionally breathable and moisture absorbent and thus, provide a cooler, more comfortable lounge chair.
Prior art shows that lounge chair structures have also gone through a metamorphic change evolving into the present day conventional lounge chair. Structures of this type are generally illustrated, for example, in U.S. Pat. No. 4,508,384 issued Apr. 2, 1985 to Lawrence E. Castelot et al. Castelot illustrates a footrest frame and a backrest frame, each of which are foldable to a posture adjacent the top surface of a seat frame. Similarly, the legs are foldable to a position adjacent the bottom surface of the seat frame, thus providing a chair that is foldable into a small compass. An alternative frame structure is shown in U.S. Pat. No. 5,061,011 issued Oct. 29, 1991 to Robert H. Miller. Miller discloses a chaise lounger having a seat, a back, and a lounge member which is removably connectable to the seat such that it extends forward of the seat. Stabilizing bars connected between the front legs and the lounge member provide supplemental support. One issue identified with seat and chair structures which has yet to be addressed is the discomfort associated with being seated in the same. A disadvantage of conventional chairs is that the frame is typically low to the ground. The present inventor has found that a need exists for a chair which may vary in height, a chair which may be in the form of a lounger in which all of the components are contained therein and which may be readily folded for storage and transportation.
None of the above patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

Detailed Description of the Preferred Embodiments
The present invention a lounger 10a. The lounger 10a, as shown in FIG. 1, is comprised of a frame 12a and a fabric cover 14a. The frame 12a includes a seat section 16a supported by front and rear U-shaped legs 18a. A back rest 22a and a foot rest 24a are pivotally attached to a rear and front portion of the seat section 16a, respectively. The front leg 18a and the foot rest 24a are each independently engagable with left and right front positioning gears 26a located proximate the front portion of the seat section 16a. The rear leg 18a and the back rest 22a are each independently engagable with left and right rear positioning gears 26a located proximate the rear portion of the seat section 16a. The positioning gears 26a are of the conventional type currently known in the prior art. The frame 12a is fabricated of a strong, durable light weight material, preferably a tubular metal, such as aluminum tubing. Unlike conventional loungers, the present invention should be dimensioned and configured to accommodate a large and/or robust person. The overall dimensions of the present inventions should preferably be six feet four inches in length, three feet in width, and at least one and one half feet high. The preferred length of the frame 12a can be achieved with a foot rest section 24a and a head rest section 22a each being two feet in length and a seat section 16a being two feet four inches in length. The fabric cover 14a is a mixture of nylon yarn and spandex fiber. The nylon yarn is preferably Supplex brand nylon manufactured by E. I. Du Pont De Nemours and Company of the United States and the spandex fiber is preferably Lycra brand spandex also manufactured by E. I. Du Pont De Nemours and Company. A mixture of eighty-six percent of nylon yarn and fourteen percent of spandex fiber provides a strong support which is both breathable and moisture absorbent. This fabric composition provides a cool comfortable fabric cover 14a. When a predetermined weight or thickness of the fabric is employed, the fabric cover 14 a can support a large or robust user (not shown).
The unitary fabric cover 14a is designed to stretch tightly over the frame such that fabric cover 14a covers all three sections of lounger 10a, i.e., the back rest 22a, the seat section 16a and the foot rest 24a.
FIG. 2 is an alternative embodiment of the lounger 10b. The frame 12b of this alternative embodiment is similar to the aforementioned frame 14a. However, this frame 12b incorporates front and rear legs 18b which telescopically or slidably engagable with the positioning gears 26b to provide a means to vary the elevation of the frame 12b to a height of up to one and one half feet or more. Additionally, laterally disposed cross-members 30 are integral with each of the legs 18b to enhance the structural integrity of the legs 18b and, in turn, of the frame 10b.
FIG. 3 shows one method of engaging and disengaging the legs 18b. The particular assembly utilizes a pin 32 attached to each end of each leg 18b. The pins 32 are each normally biased inward into and through an aperture 34. This is accomplished through the use of a spring 36 carried by the pin 32. A plurality of holes 38 are provided in an elongated member 40 which extends from each of the positioning gears 26b. The elevation of the frame 10b is adjusted simply by independently withdrawing the pin 32 from the leg 18b clear of the holes 38 in the elongated member 40 and by slidably adjusting the elongated member 40 within the leg 18b, thus varying the hole 38 which aligns with the pin 32. Once the elongated member 40 has been adjusted to the desired length, the pin 32 may be releases to engage with the hole 38 nearest the pin 32. The legs 18a may be removed entirely, simply by withdrawing the pins 32 and holding the pins 32 in this withdrawn posture until the respective elongated members 40 are each slidably disengaged from the respective ends of the legs 18a.
Referring back to FIG. 2, the unitary fabric cover 14b may be removable. A fastener 42 is provided preferably at the forward end of the foot section 24b of the fabric cover 14b. The fabric cover 14b may be removed by unfastening the fastener 42 and by removing the legs 18a in the above prescribed manner. Having accomplished this, the fabric cover 14b may be slipped off the frame 12b in the direction A. This enables the fabric cover 14b to be machined washed. Alternatively, the fastener 42 may be eliminated if at least one lateral opening 44 is provided either between the seat section 16b and the back rest section 22b or between the seat section 16b and the foot rest section 24b. This enables the frame 12b to ingress into and egress from the fabric cover 14b merely by manipulating the frame 14b.
Also shown in FIG. 2 is a supplemental support 46 which may be permanently or removably attached to the seat section 16b. The support 46 may be fabricated of the same material as the cover 14b or may be a webbed nylon strap, similar to that used for automobile safety belts. The fabric cover 14b may cover both the front and the back side of the frame 12b, concealing the support 46 therein. This support 46 ensures that the lounger 10b will sustain a large robust user.
FIG. 4 shows the directions in which the legs 18a,18b the back rest section 22a,22b, and the foot rest section 24a,24b may be manipulated or may move relative to the seat section 16a,16b. The legs 18a,18b are foldable toward each other and toward the seat section in the direction B. The legs 18a,18b are further pivotal away from each other in the direction C and are engagable in a locking position. The foot rest section and the back rest section are foldable toward each other and toward the seat section in the direction D, are further pivotal away from each other in the direction E, and are engagable in a plurality of locking positions through the movement in the direction D.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
