PURPOSE
[0001] This request for Invention Patent is for an improved deckchair that provides various
advantages as regards the function for which it is intended, to be explained later
on, apart from others inherent to its organization and constitution.
HISTORY
[0002] At present and as a reference to the state-of-the-art, mention should be made that
deckchairs of the type described are known, consisting of a framework that includes
two basic parts, one permanent consisting of the feet and the bed, and the other which
is movable and associated to the former consisting of an adjustable back with position
handles on each side.
[0003] The deckchairs of which the present state-of-the-art is composed have certain structural
and functional inconveniences.
[0004] Amongst these, mention should be made of the means that provide the optional adjustment
for tilting the back until a flat angle is formed. At present, these means generally
consist in an articulated bridge provided on both sides with a series of teeth that
form a series of attachments on a crosspiece. These means have the inconvenience that
when the user sits on the deckchair the canvas tightens and causes the back to rise.
[0005] Likewise, there is a structural inconvenience which arises from the shape of the
supports of the deckchair, in the form of two "V"-shaped parts that have an angular
and symmetric opening on the sides which cause one or another end of the deckchair
to rise when the user does not sit in the middle of it.
[0006] A structural and functional inconvenience is caused by the adjustable back when one
sits on the deckchair lowered and coplanar with the bed. In this position the upper
side of the back rests on the transversal side of the frame or framework of the bed,
with the risk of jamming the fingers of the user causing injury.
DESCRIPTION OF THE INVENTION
[0007] The improved deckchair, purpose of this invention, introduces improvements in the
manufacture of stackable deckchairs, that advantageously resolve the inconveniences
mentioned briefly in the above paragraph.
[0008] Said deckchair is built according to a light but resistant structure based on reinforcements,
ergonomic and stackable, with blunt and no sharp edges, consisting of three consistent
parts in a monobloc chassis with reinforcements, a back and an adjustable support
frame of the back, in such a way that the back has been placed in the completely vertical
position and its adjustable support frame in the completely horizontal position with
the result that both are trapped if an effort is made to extract either one in any
other position.
[0009] The adjustable support system of the back consists in an articulated frame that establishes
a series of attachments in corresponding housing in the form of "lock eye" made on
the chassis of the deckchair. These attachments facilitate blocking of the back thus
avoiding it being raised, usually when the user sits on the deckchair and causes the
canvas to be tightened.
[0010] Likewise, the deckchair has asymmetric "V" legs with truncated vertices and provided
with synthetic resin nonskid support wedges that affect the stability of the deckchair
and prevent unbalancing when the weight of the user is not centered.
[0011] Furthermore, the risks of accident such as jamming the fingers between the folding
back and the frame of the deckchair are eliminated by providing a back with butts
which, in the folded position of the back, rest on the frame of the deckchair providing
room between both so that the fingers cannot be jammed between the back and the chassis
of the deckchair.
[0012] Finally, apart from the mentioned advantages, the invention provides other substantial
improvements in the general idea of the frame of the deckchair that facilitate mounting
the canvas, its tautening and retautening by means of hooks that are joined to the
canvas with clinches, although this could also be done with buttonholes; shaping the
surface of the bed with a highly resistant transpirable and electro-welded fabric,
manufactured with high tensile strength polyester thread, plasticized and resistant
to ultraviolet rays, in various colors and which serves as a support for any serigraphed
logo; manufacture of the frame in metallic materials such as iron, aluminum and others,
as well as synthetic resin; and the obtaining of an alternative surface of the bed
and back based on small planks in various colors and easily replaced.
[0013] To complement the description which follows and in order to help with a better understanding
of its characteristics, this descriptive report includes a set of drawings the figures
of which represent the most significant details of the invention in an illustrative
but not limiting way.

DESCRIPTION OF A PREFERRED PERFORMANCE
[0029] In view of the figures indicated above and in accordance with the numbering used,
a preferred although not limited performance of the invention can be seen. This consists
of a stackable deckchair, composed of an ergonomic structure with 5 blunt and no sharp
edges and includes a monobloc chassis -1- with reinforcements, a foldable back -2-
and an adjustable support frame -3- of the back, with joints that make the positioning
of the back completely vertical, whilst the positioning of the adjustable support
frame is completely horizontal (figure 14), so that neither can be extracted in any
other position.
[0030] The chassis -1- constitutes the supports -4- and -5- of the deckchair. These have
an angular, asymmetric "V" shape so that their sides form a different angle of incidence
on the floor, with said "V" shapes truncated in their vertices according to the straight
sections -6- and -7-, provided with synthetic resin nonskid support wedges (figure
8), thus avoiding raising or sliding of the chassis by one or another of its ends
when the weight of the user is not centered.
[0031] The adjustable support frame -3- of the back -2- is located behind the latter and
provided with a series of projections -9- that establish a series of attachments on
some orifices -10- in the form of "lock eye" suitably made on the chassis -1- for
the purpose of optionally graduating the slant of the back until forming a completely
folded position. This has the peculiarity that said orifices -10- in "lock eye" facilitate
blocking the back in order to prevent it from accidentally raising due to tightening
of the canvas when, for example, the user sits on the deckchair.
[0032] Likewise, and for this purpose, the back -2- in its joining with the adjustable support
frame -3- has a butt -11-that is received under pressure in a housing -12- of the
chassis -1- of the deckchair, thus facilitating blocking of the back -2- when this
is completely folded on the chassis -1-, as indicated in figure 2 and in detail in
figure 12.
[0033] The deckchair is provided with a safety system to prevent damage usually caused when
the fingers of the user become jammed between the chassis -1- and the foldable back
-2- of the deckchair, consisting in butts -13- placed under the area in front of the
back -2-. These, in the folded position of the back, rest on the chassis -1- of the
deckchair and leave a safety space between the chassis and folded back, as shown in
figure 2 and in detail in figure 11.
[0034] The support surface of the deckchair can be composed of successive small interchangeable
planks -14- with elastic projections -15- that are connected under pressure in housing
arranged along the profile of the chassis -1- of the deckchair, as indicated in figures
6 and 10, or by a material -16-consisting of a transpirable fabric made of plasticized
polyester resistant to ultraviolet rays that includes an antifungus protection and
prevents the stains caused by humidity.
[0035] This fabric is made by thermo-welding, thus preventing it from being torn, and offers
easy cleaning and a high degree of comfort and recovery, thanks to a securing system
on the chassis -1- of the deckchair composed of buttonholes or hooks-17- joined to
the fabric with clinches, attached to elastic cords -18- which are arranged in zigzag
around stubs -19-projecting out from the profile of the chassis -1- of the deckchair
(figure 5), allowing perfect tautening of the fabric as indicated in figures 7, 9a
and 9b.
[0036] Furthermore, the edge of the fabric adapts perfectly to the profile of the deckchair
chassis, as indicated in figure 7, due to the fact that grooves of a horseshoe shape
have been provided in order to suitably house the canvas around the legs of the deckchair.
