BACKGROUND OF THE INVENTION
[0001] The present invention relates to improvements to the conventional umbrellas as well
as to the beach umbrellas.
[0002] The conventional umbrellas, so far used for protecting against rain, as they are
closed have their wetted portions directed outwardly with a consequent discomfort
for the umbrella bearing user. Moreover the known umbrellas are devoid of a sufficiently
large resting base effective to permit the umbrella to support itself vertically,and
require resting means, such as an umbrella stand.
SUMMARY OF THE INVENTION
[0003] Thus,the main object ef the present invention is to provide an umbrella,both of the
conventional impermeable type and of the beach type, comprising a supported covering
cloth, which, in the opened condition thereof resembles to the known umbrellas, but,
in the closed condition thereof,has the wetted cloth directed inwardly.
[0004] Another object of the present invention is to provide such an umbrella effective
to support itself autonomously, without the need of any umbrella stand.
[0005] According to one aspect of the present invention the aforesaid objects are achieved
by an umbrella comprising a central rod ending,at one end thereof, with a handle and,
at the other end thereof,with a ferrule,a covering cloth and ribs for supporting said
covering cloth as well as further coupling ribs,a sliding member mounted on said central
rod,characterized in that said covering cloth supporting ribs have one end thereof
hinged to said sliding member and the other end thereof rigid with the cloth covering
periphery and in that said coupling ribs have a fixed end pivoted to one end of said
central rod and the other end thereof coupled, by means of a hinge member, to said
covering cloth supporting rib.
[0006] According to another aspect of the present invention,which is particularly effective
for umbrellas provided with a rigid covering cloth,the umbrella further comprises
auxiliary coupling means effective to couple one end of the sliding member to the
supporting ribs, which auxiliary coupling means engage with said supporting ribs by
an engagement means. Said engagement means is effective to exercise a force at the
contact point between said auxiliary coupling means and supporting ribs in such a
way that said supporting ribs can assume a suitable arrangement during the umbrella
opening operation.
[0007] According to another aspect of the present invention,said auxiliary coupling means
consist of ribs,and the engagement means consists of a cord,rope or the like effective
to be inserted,in a zig-zag arrangement,between said ribs and provided for possibly
engaging, by means of a knot member,each said supporting rib with the corresponding
auxiliary rib.
[0008] A preferred embodiment of the present invention provides that the covering cloth
supporting ribs are slightly bent at the coupling zone thereof to said sliding member
on the central rod to facilitate the sliding off of water on the umbrella cloth as
the umbrella is in its open condition.
[0009] A further preferred embodiment of the present invention provides that the supporting
ribs,and possibly the auxiliary coupling ribs,which are located outwardly as the umbrella
is in its closed condition,are completely or partially closed by a further cloth layer,this
cloth being located in the inside of the umbrella as the latter is open.
[0010] A further embodiment of the present invention provides that each supporting rib and
auxiliary coupling rib are engaged in pairs by means of a loop or binding member.
[0011] A particular embodiment of the present invention provides that the coupling means
consists of a cord, rope or rib inserted into a hole formed at a suitable position
through the supporting rib.
[0012] Another embodiment of the present invention provides that the closed umbrella is
provided with a resting base consisting of the ends of the ribs projecting from the
umbrella ferrule,which base is sufficient to support the umbrella in a vertical position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] A first embodiment of the umbrella according to the present invention will be described
hereinafter with reference to figs.1,2,3 and 4.This embodiment is particularly effective
for umbrellas having a thin cloth.
[0015] Fig.l illustrates the umbrella in its open condition.It is formed by a sliding member
10 mounted on the umbrella central rod 14,and it is used in the conventional way.
[0016] In place of the sliding member it is possible to use any other known device for opening
or closing umbrellas,such as spring devices.
[0017] The central rod 14,at one end thereof, bears the ferrule 13 and, at the other end
thereof, it is provided with the handle 15. The covering cloth supporting ribs are
of two types:a first type ll for supporting said covering cloth and a second type
12 for coupling.The supporting rib 11 is hinged at one end thereof to the sliding
member 10 and, at the other end thereor,is rigid with the covering cloth periphery.
The coupling rib 12 has its fixed end pivoted to one end of the central rod 14, whereas
the other end thereof is coupled to the supporting rib 11 by means of the hinge 20.
[0018] Fig.2 illustrates the umbrella during the opening operation(according to the direction
of the arrows A) or closing operation (according to the direction of the arrows B).
The hinge 20 is effective to permit mutual rotation of the ribs 11 and 12 with the
cloth, being generally wetted,bent or folded inwardly.
[0019] The supporting ribs 11 coupled to the sliding member 10 are slightly bent as indicated
at lla in fig.4.This arrangement has been selected in order to provide an evenly convex
outside surface for the umbrella.
[0020] Fig.3a illustrates the umbrella in its closed condition,in which the covering cloth
30 is bent in the inside of the umbrella. On the outside of said covering cloth 30
may be provided the cloth 40 effective to completely or partially cover the ribs 11,which
cloth 40 has not been shown in the other figures for simplicity.
[0021] As the umbrella is in its closed condition, it may be rested on the ground.Infact
the ends of the ribs ll,indicated at l6,form a circle about the ferrule 13,as it is
illustrated in fig.3b.
[0022] The resting area of this assembly is accordingly a large one and it is sufficient
to hold the umbrella in an upright position,without the need of any umbrella stand.
Thus the double object is achieved of not leaving the wetted cloth exposed which would
be susceptible of wetting the user.
[0023] Fig.4 illustrates a second embodiment of the sliding member 10,represented by an
enlarged sectional view,which is provided with a slot 25.This sliding member is further
provided with such a large base effective to allow for the ribs 11 to be located near
the rod 14,as the umbrella is closed, as it is illustrated in fig.3a.
[0024] Figs.5 illustrates a second embodiment of the present invention. This embodiment
is particularly useful as the umbrella covering cloth 30 is of a rigid type susceptible
to hinder the umbrella opening, and more specifically,to prevent the umbrella outside
surface to assume its convex shape as the umbrella is open.ln this embodiment the
umbrella is provided with auxiliary ribs 42 rigid,at one end thereof,with one end
of the sliding member 43 therefrom the supporting ribs 11 extend.Said sliding member
43 is provided,above the base 28, with a second portion 46 either coupled or not to
said base 28, from the end 27 whereof said auciliary ribs 42 extend. These latter
are provided with a looped end 44 which is inserted into the supporting rib 11 and
locked by the hinge 20. Each auxiliary rib 42 is coupled to the corresponding supporting
rib 11 by an engagement means, consisting of a cord or rope 41 which is inserted,in
a zig-zag arrangement, between the ribs 42 and 11 and which is also effective to couple,
by a knot, two corresponding ribs of the auxiliary type 4,2 and the supporting type
11. This rope 41 is loose as the umbrella is closed but,as it is opened,said rope
is stretched in such a way as to exercise a force at the contact point 50 between
the rope 41 and the auxiliary rib 42 and related supporting rib 11. This force aids
the opening of the umbrella.
[0025] Furthermore, the outside surface of the umbrella is evenly convex.
[0026] A variation of this embodiment provides that the supporting ribs 11 and auxiliary
ribs 42 are coupled in pairs through suitable size ring or loop members.
[0027] The auxiliary rib 42 may also be inserted into a hole 51 formed through the rib and
suitably reinforced. Alternatively, in place of the rib 42 it is possible to use a
cord or wire made of any suitable not deformable material,and indicated at 45. This
variation is illustrated in fig.6.Said cord 45, through said hole 51 provides a force
which is useful for opening the umbrella.
[0028] As it has been thereinabove mentioned,this second embodiment provides for the use,in
addition to the means of the first embodiment,of auxiliary coupling means and engagement
means for the supporting ribs 11,in order to facilitate the opening of the umbrella
as this latter is made of a rigid material. The first embodiment,on the other hand,
is particularly effective for umbrellas provided with a rather thin covering cloth
and it provided a particular light umbrella.
