ABSTRACT:
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to folding furniture, and more particularly to an inclined back support arrangement for folding furniture which provides the user of the folding furniture with an inclined back support.
2. Description of Related Arts
Referring to
FIG. 1
of the drawing, a conventional foldable chair comprises a foldable chair frame A
1
constructed by metal tubes and a seat fabric B
1
. The foldable chair frame A
1
comprises a plurality of construction tubes A
11
to construct a back frame A
2
and a seat frame A
3
for supporting the fabric seat B
1
. The seat frame A
1
comprises a front pair, a back pair and two side pairs of the construction tubes, wherein each pair of the construction tubes are pivotally connected together where they cross so that the chair frame A
1
can be easily unfolded to provide a rigid cross-support for use and be folded up for storage.
Because such a conventional foldable chair can be quickly and easily unfolded for use and folded into a compact for carriage, a user can carry the foldable chair to everywhere such as campground or beach. However, the back frame A
2
of the conventional foldable chair merely comprises a pair of elongated construction tubes A
21
vertically connected to the seat frame A
3
for supporting a back support portion B
11
of the fabric seat B
1
in an upright manner.
Accordingly, the user of such conventional upright foldable chair is forced to sit upright on the chair. In other words, none of the conventional folding chair provides an inclined back support that enables the user to inclinedly lay his or her back thereon comfortably.
Moreover, most people trend to sit down with their back inclined backwards; therefore most of the furniture chairs are designed to have an inclined back. However, such upright back frame A
2
of the conventional folding chair fails to well support the inclined back of the user.
SUMMARY OF THE PRESENT INVENTION
A main object of the present invention is to provide an inclined back support arrangement specifically incorporated with folding furniture, which can well support a user's back so that the user is capable of lying on the folding furniture naturally and comfortably.
Another object of the present invention is to provide an inclined back support arrangement for folding furniture which can be quickly and easily folded into a compact unit for carriage and storage and unfolded for use.
Another object of the present invention is to provide an inclined back support arrangement for folding furniture, which inclination is adjustable, that is the slope of the back frame can be adjusted to fittingly support the user's back.
Another object of the present invention is to provide an inclined back support arrangement for folding furniture, which enables the back frame to be inclinedly supported without altering or complicating the back frame and seat frame structure.
Another object of the present invention is to provide an inclined back support arrangement for folding furniture, which can even reinforce the structure of the seat frame and enhance the seat frame's weight supporting ability.
Another object of the present invention is to provide an inclined back support arrangement for folding furniture, wherein the weight of the user applied on the seat frame and the back frame will further ensure the construction of the inclined back support arrangement.
Accordingly, in order to accomplish the above objects, the present invention provides a folding furniture, comprising a seat frame and a back frame constructed to support a fabric seat thereon.
The seat frame comprising two side leg frames and a construction leg frame foldably supported between the two side leg frames. Each of the side leg frames comprises a front side crossed leg and a rear side crossed leg pivotally connected together where they cross, a front frame joint pivotally connected to a top end of the rear side crossed leg, and a back frame joint pivotally connected to a top end of the front side crossed leg. The back frame comprises a pair of back frame legs slidably passing through the two back frame joints respectively.
The folding furniture further comprises an inclined back support arrangement which comprises a pair of back support coupling means for pivotally coupling two bottom ends of the two back frame legs with two lower portions of the two rear side crossed legs of the seat frame respectively, so as to inclinedly support the two back frame legs in position.
Whereby, by varying the coupling position of the two rear side crossed legs with the two bottom ends of the two back frame legs can adjust the inclination of the two back frame legs of the back frame.
