Description
OBJECT OF THE INVENTION
[0001] The present invention relates to a folding umbrella which
can be carried for the user hold on the back.
FIELD OF THE INVENTION
[0002] This invention is applicable within the industry dedicated
to the manufacture of umbrellas and parasols, specifically in the
auxiliary industry of umbrellas with folding handles.
BACKGROUND OF THE INVENTION
[0003] It is common that umbrellas, with or without folding handle,
have certain inconveniences to users, as having to be carried with
one hand, make impossible the use of both hands at once. It must be
taken into account that people in wheelchairs, crutches or people
who push strollers need two hands free for the handling, and in
case of rain, this gives rise a problematic situation for these
people.
[0004] It's known in this sector of the industry some models which
not contribute to the state of the art the novel features proposed
by the present invention. Thus, the document ES281276Y describes an
umbrella, which parabola has and elliptical shape, with a greater
horizontal width, with the possibility of use by two people at the
same time with certain comfort. The elliptical parabola-type
umbrellas present the disadvantage of occupying a large space,
causing embarrassing situation. The document U0217628 proposes an
umbrella with non-automatic folding handle with cumbersome use. The
umbrellas with non-automatic folding handle require time enough for
its opening, being wet thus the user in the rain. The document
ES216848 informs about an umbrella of extensible handle which,
although smaller when folded, must be carried manually. Also, the
document U0124048 describes the opening and closing of an
automatic-shape umbrella but manual handling. The document U0184756
describes an umbrella with articulated rods, which can be opened in
different ways and at different angles, but its use is complicated
and present the disadvantage that its opening is too long, time
enough for the user receives the effect of the rain. Analogously,
the document ES 2223398 T3 relates to the joint of the rods and a
peculiar form for its extension. The document ES1039207 U describes
a design of ovoid-shape umbrella, of questionable advantage over
standard umbrellas, and furthermore presents a large occupation of
space.
[0005] Further, all these documented systems of umbrellas presents
against the proposed invention the disadvantage of the need of
being carried by the user using the hands, giving rise various
inconveniencies, e.g. situations of neglect and above all, have
always one hand occupied.
[0006] There are documents that describe umbrellas which are
transported attached to backpacks, but they are still umbrellas
with conventional opening, and they present the problem that in
order to open them, it must be get ride of the backpack.
Furthermore, the central axis of the umbrella is not the same of
the user and, thereby, does not accomplish correctly its protective
function.
DESCRIPTION OF THE INVENTION
[0007] The invention described in this specification provides
answers to the above issues and consisting of an umbrella with a
mechanical system for opening whose utility can be many varied,
having the advantage that both the opening and the closing of the
umbrella is made with one hand. The entire set is housed in a cover
to which can be joined a harness or can be adapted to be carried in
a backpack. The umbrella can be opened or closed without the need
of removing said harness of backpack, only with a simple arm
movement. In case of rain, the umbrella is carried open, hold to
the back and without using the hands.
[0008] The invention is formed by a structure of tubes and guides,
and by actuating and movement elements, which deploy and fold the
rods of the umbrella.
[0009] The structure consist of a pair of parallel tubes, which are
referred to as internal tubes, which are linked in parallel and
severally at the bottom of a bottom plate and at its centre by a
middle plate. The cover has attached inside a pair of parallel
grooved tubes, which are referred to as guides, to which are
adjusted the internal tubes and by which can slide. The sliding of
the internal tubes out of the cover is limited by a stop or stop
element placed inside the cover. Said internal tubes are connected
by joints to another pair of tubes, which are referred to as
oscillating arm. The oscillating arm can carry a long piece, which
is referred to as arm guide. The oscillating arm is connected by a
joint to a body formed by a pair of guides, one upper and other
lower, and also by a mechanical-type connection for deployment of
rods that, preferably, will be gear teeth. Some will be fixed on
the oscillating arm, and others will be in the body and rotate
freely. The upper guide of the body and the lower guide of the body
are separated by a certain distance. The end of the body opposite
to the union with the oscillating arm has a pulling device, which
will be the element that is held with the hand in order to open and
close the umbrella. The part of the body which has the pulling
device, it will be considered as front of the body and the part
that is joined to the oscillating arm, as rear part of the
body.
[0010] When the structure is deployed, this is out of the cover and
is fasten thereto by the part of the internal tubes which is inside
the cover when these have been reached their top.
[0011] In this situation, the oscillating arm will be in aligned
position with the internal tubes, and the body will form an
approximate angle of 90.degree. regarding to the oscillating arm.
When the structure is deployed, the set is inside the cover, the
oscillating arm is folded over the internal tubes and the body is
folded over the oscillating arm.
[0012] The actuating and movement elements are arranged to deploy
the rods of the umbrella at the moment in which the structure is
get out of the cover. A group of rods is joined to the body by a
fixed rotary union, and three sliders which slip along the body by
rotary union. Two sliders are located in the upper guide of the
body, and a third, in the lower guide. The movement of these rods
will be both rotation and translational. The displacement of two of
the sliders, one located in the upper guide of the body and the
other located in the lower guide, is achieved by a cable to which
the sliders are joined. The cable forms a closed circuit and is
placed along the body and the oscillating arm, preferably along the
arm guide. The slider located in the front part of the upper guide
is moved due to the displacement of the other slider located in the
upper guide. At the end of the oscillating arm, which is joined to
the internal tubes, and at each end of the body there is a series
of pulleys which help to the displacement of the cable. The ends of
said cable are joined to a movable part, referred to as arm slider.
The oscillating arm can have an arm guide along which would be
moved the arm slider. Tie-rods connect the arm slider with the
middle plate. Another pair of rods is joined to a rotating element
in the rear part of the body, preferably to the gear teeth of the
body.
[0013] When the structure is deployed, the arm slider makes that
the cable pulls the sliders of the body, causing that the sliders
located in the upper guide of the body are displaced toward the
front part of the body, and that the slider located in the lower
guide is displaced toward the rear part of the body. This causes
that the rods of the umbrella attached to sliders, are opened and
spread. The rotating movement of the body when is deployed, makes
that the rods attached in its rear part turn approximately
200.degree. and then they are deploy. The rotating movement of
these rods is transmitted preferably by means of gear teeth. When
the umbrella is open, said rods turn in a near vertical plane to
the floor, and the rods attached to the sliders turn and are
deployed, in a horizontal plane to the body. When the structure is
folded, the sliders are moved in opposite direction to the earlier,
which causes that the rods attached to that are closed and
gathered. The rods attached to the rear part of the body are
gathered turning in opposite direction to the opening.
[0014] In order to ease the opening of the umbrella, the body
carries the pulling device in the front of the body. When the
umbrella is closed, and therefore is inside the cover, the pulling
device stick up slightly in order to can hold it with comfort. Once
the umbrella is placed on the back, when the pulling device is
powered up, the deployment of the structure is generated, whose
final movement is completed when the rods are completely deployed,
leaving the umbrella open. When close the umbrella is desired, the
pulling device is pushed back and the structure is deployed, being
closed the umbrella and being leaving housed inside the cover. In
order to ease the fold and keeping of position of the structure
when it is deployed, in the part of union between the internal
tubes and the oscillating arm are placed springs misaligned
regarding to the vertical.
[0015] Once the umbrella is opened, the design of the structure
makes that the umbrella is positioned so as protect completely to
the user.
[0016] Also the invention has the possibility of can be coupled to
backrests for wheelchairs or strollers, it can be used not only as
umbrella but also as parasol.
[0017] The features and advantages of the invention will become
clearly apparent from the detailed description that follows in a
preferred form of embodiment, given only by way of illustrative and
non-limiting example, with reference to the accompanying
figures.

PREFERRED EMBODIMENT OF THE INVENTION
[0027] The detailed description of a preferred embodiment of the
invention is going to be carried out hereinafter with the help of
the accompanying drawings, through of which are used the same
numerical references for designate the equal to similar parts, and
takes into account the explanation exposed of the invention.
[0028] In the FIG. 1, it can be seen a schematic lateral view of
the cover (1) and its content. The umbrella is folded inside,
sticking up the pulling device (8) in the upper opening of the
cover (1). The guides (2), internal tubes (3), oscillating arm (4)
and body (5) are observed. The internal tubes (3) are joined to the
oscillating arm (4) by joint with pins (6) and, in turn, the
oscillating arm (4) is joined to the body (5) by joint with the pin
(7).
[0029] In the FIG. 2, it can be seen the development of the
position of the structure in a middle step of the opening or
closing process of umbrella. The internal tubes (3) has been
displaced vertically being slide along the guides (2), and both the
oscillating arm (4) and the body (5) are in a deployment position
in case of opening of the umbrella, or folded in case of closing of
the umbrella.
[0030] In the FIG. 3, it shows the position that keeps the
structure completely deployed.
[0031] In the FIG. 4, it can be seen a schematic perspective view
of the structure and the mechanism in deployed position. The
internal tubes (3) have been displaced along the guides (2) until
de stop (10) and they are attached severally by the bottom plate
(9) and the middle plate (11). The stop (10) delimits the advance
of the internal tubes (3) when makes contact with the bottom plate
(9). The internal tubes (3) are joined to the oscillating arm (4)
by pins (6). The oscillating arm (4) is joined to the body (5) by
the pin (7). In the front part of the body (5), the pulling device
(8) is observed. The movement among the oscillating arm (4) and the
body (5) transmits movement to the teeth of the mobile gear (13)
through a fixed gear (12). The upper guide of the body (5) carries
two top sliders (19, and 20) and the lower guide carries a bottom
slider (21). The sliders (19, 20 and 21) are moved along the body
(5), and said movement is provided by a cable (15) to which are
connected the top slider (20) and the bottom slider (21). The ends
of the cable (15) are connected by an arm slider (16). The cable
(15) is placed along the body (5) and an arm guide (14) which forms
part of the oscillating arm (4). The arm slider (16) is displaced
along the arm guide (14). Tie-rods (17) connect the arm slider (16)
with the middle plate (11). The end of the arm guide (14) of the
oscillating arm (4) holds a pulley (18).
[0032] In the FIG. 5 the body (5) is observed in more detail. The
union among the oscillating arm (4) and the body (5) is carried out
with the pin (7). The fixed gear (12) which is located in the
oscillating arm (4), makes that the mobile gear (13) located in the
body (5) is moved both in the folded and in the deployed. The upper
guide of the body (5) has two top sliders (19, and 20) which are
moved along the body, and the lower guide a bottom slider (21)
which is also moved along the body (5). The top sliders (19 and 20)
are also slide along a stop-guide (22) which helps to the
coordination of its movements and is fixed to the body (5) at its
ends. When the umbrella is opened, the cable (15) causes that the
rear top slider (20) is displaced in direction of the pulling
device (8), and the bottom slider (21) in the opposite direction.
When the umbrella is closed, the cable (15) makes that the rear top
slider (20) be displaced in the opposite direction to the pulling
device (8), and the bottom slider (21), in the direction of the
pulling device (8). The right coordination of these movements is
fundamental for the deployment and folded of the umbrella.
[0033] In the FIG. 6, it can be seen the spring (23), which helps
to keep the right position of the oscillating arm (4) regarding to
the internal tubes (3). When the umbrella is opened, the spring
helps to maintain the position. When the umbrella is being closed,
the spring helps to the fold. The spring (23) is misaligned
regarding to the rotation axis.
[0034] In the FIG. 7, it can be seen the run that makes the cable
(15). The set of pulleys (18, 24, 25, and 26), both at the end of
the arm guide (14) and in each end of the body (5), helps to avoid
the friction en the cable (15). The front top slider (19) is not
connected to the cable.
[0035] In the following FIGS. 8, 9, and 10, the deployment of the
rods of the sliders (19, 20, and 21) is showed. Both in the fold
and in the deployment, all rods are moved synchronously.
[0036] In the FIG. 8, it is show the relation among the
displacement of the rear top slider (20) along the body (5) and the
opening or closing of the rods (27), and how that displacement
transmits movement to the rods (27), which are attached to the rear
top slider (20) through a rotating point, and to the body (5)
through a fixed rotating point. In the deployment, the rear top
slider (20) moves toward to the pulling device (8) and the rods
(27) are deployed. In the fold, the rear top slider (20) moves back
in opposite direction to the pulling device (8) and the rods (27)
are folded.
[0037] In the FIG. 9, it is shown the relation among the
displacement of the bottom slider (21) along the body (5) and the
opening or closing of the rods (28), and how that displacement
transmits movement to the rods (28), which are attached to the
bottom slider (21) through a rotating point, and to the body (5)
through a fixed rotating point. In the deployment, the bottom
slider (21) moves in opposite direction to the pulling device (8)
and the rods (28) are deployed. In the fold, the bottom slider (21)
moves back in opposite direction to the pulling device (8) and the
rods (28) are folded.
[0038] In the FIG. 10 it is shown the relation among the
displacement of the top sliders (19, and 20) along the body (5) and
the opening or closing of the rods (29), and how that displacement
transmits movement to the rods (29), which are attached to the top
sliders (19, and 20) through rotating points. In the deployment,
both top sliders (19, and 20) moves in direction to the pulling
device (8). The front top slider (19) moves until a final stop of
run. The rear top slider (20) continues with the advance and the
rods (29) are deployed. In the fold, the top sliders (19, and 20)
moves back in opposite direction to the pulling device (8).
[0039] The front top slider (19) moves back until a final stop of
run and the rear top slider (20) continues with the backward
movement, making that the rods (29) are folded.
[0040] The FIGS. 11, 12, 13, and 14 show the movement of the rear
rods (30), which is carried out preferably by means of a teeth of a
mobile gear (13).
[0041] The FIG. 11 shows, in a top view, the rear rods (30) in
folded position hold to the teeth of the mobile gear (13), located
in the rear part of the body (5).
[0042] The FIG. 12 shows, in a top view, the rear rods (30) in
deployed position due to the rotation of the teeth of the mobile
gear (13), located in the body (5). The opening angle is produced
due the tension of the cloth of the umbrella.
[0043] The FIG. 13 shows a side view of the oscillating arm (4) and
the body (5) in folded-position. The fixed gear teeth (12) of the
oscillating arm (4) are in contact with the teeth of the mobile
gear (13) of the body (5). The rear rods (30) are mounted on the
body (5) and are held to the mobile gear (13).
