BRIEF SUMMARY
FOLDING LOUNGE CHAIR
The present invention relates to a lounge chair capable of being folded to a reduced and compact form, simple to use and easy to carry.
PREVIOUS TECHNIQUE
The folding of a lounge chair is traditionally done by folding the lower portion over the middle one and the upper portion over the two previous portions. Thus, the patent U.S. Pat. No. 4,773,708 describes a folding lounge chair with a frame composed of two parallel longitudinal elements, each of which is provided with two hinges located at each end of the central portion forming the seat, to which are hinged folding legs.
The upper and lower portions located on each side of the seat are composed in one single piece by the longitudinal elements and a support bar at each end. Each of these portions includes a fabric stretched between the two longitudinal elements. The reduction of the volume according to this technique is limited to the size of the seat, because the support bars and the folding legs prevent the longitudinal elements from being brought together.
SUMMARY OF THE INVENTION
The lounge chair, according to the invention, remedies these inconveniences, thanks to a folding device allowing the folding lengthwise and a transversal reduction to give the chair a compact configuration, easy to carry. The lounge chair, according to the invention, is the type that is formed by a frame that has parallel longitudinal elements each of which is provided with two hinges defining a central portion forming the seat to which are jointed folding legs, an upper portion and a lower portion, each of which includes a fabric stretched between the longitudinal elements, the frame including also at least two supporting crossbars arranged at its extremities, the folding legs are mounted at each end of the seat on joints fastened to the respective hinges, these joints allowing the legs once folded to be juxtaposed in pairs, the supporting bars are provided with a joint allowing them to lie alongside the longitudinal elements, to allow them to be brought together on folding, and the placing of the slack fabrics which then lie outside the structure. The lounge chair, in accordance with the invention, comprises locking devices for locking and stabilizing the chair when it is fully unfolded and ready for use.
In accordance with a first form of realization, each crossbar is provided at one end with a joint to the longitudinal element, or the respective leg, as well as with a locking device at each end. The said locking device has a pin activated by a button located on the side of each longitudinal element, and on the side of each leg opposite to the one that has the pin. The fabrics are fastened to one of the longitudinal elements on the same side of the frontal frame for each of them, and received through the other longitudinal element. Preferably each fabric is introduced inside a slot present in the structure of the element parallel to the one where it is fastened. Each support bar is provided with a canal in which is inserted the head of a bolt fastened to each leg and each longitudinal structure, this canal ends in an arc on the side of the joint to the support bar. The two longitudinal elements are provided on the outer side of their lower and upper portion, with a recess so that the two crossbars, once folded, locate themselves in it, and a compact block is realized. Each fabric is provided at its free end with a strong rod equipped with a ring in its middle, which locks itself against the slots when opening the longitudinal structures, thus the closing of these structures takes effect by a traction exerted on these rings. A shoulder strap fastened to the folded lounge chair allowing to secure the fabrics encircling the lounge chair thanks to a strip with spikes and facilitates its transportation. The invention foresees also an automatic rolling up device with springs located inside the longitudinal element intended to receive the fabrics.
In accordance with a second form of realization, the folding crosslegs are cruciform, provided with a fr
