Description
[0001] This application claims priority from German application No.
DE 202015001957.9 filed on Mar. 13, 2015, the disclosure of which
is incorporated herein by reference.
TECHNICAL FIELD
[0002] The invention relates to a sun and weather protection
device, particularly a parasol and further roof constructions.
BACKGROUND OF THE INVENTION
[0003] In addition to other parasol constructions, parasols
configured as a support rod with cross struts are known, for
example from CH 314813 (Albert Glatz), CH 395446 (Karl Strotz) and
CH 501798 (Albert Glatz).
[0004] The advantages of these sail-shaped parasols are, amongst
others, their rectangular shape and the adaptability to the
position of the sun. A disadvantage is the complicated mounting of
the separate fabric sheets onto the support rod. A particularly
disadvantageous aspect is that adjustment of the roof to follow the
variable path of the sun which depends on location, season and time
of the day in accordance with prior art requires releasing and
fixing again a plurality of locking devices. Also disadvantageous
is that in some cases the clamping action of the locking devices
according to the prior art is weak. In DE 24 30 234 A1 there is
disclosed a hinge connection having only a single clamping screw. A
disadvantage of the hinge connection of DE 24 30 234 A1 is the weak
clamping action and the multipiece configuration of the hinge
parts.
SUMMARY OF THE INVENTION
[0005] Therefore, the object of the present invention is to
eliminate the above mentioned weak points of the prior art and,
accordingly, to achieve the advantages of having fewer individual
parts, a stronger clamping force and an operation which is as easy
as possible and requiring only a single operating element (e.g. a
clamping screw) for all adjustment directions.
[0006] The object of the invention is achieved with a sun and
weather protection device, particularly a parasol, with a standing
rod, a support rod and a flexible protecting surface. The proposed
sun and weather protection device comprises two hinge halves with
closed gripper clamps and a toothed rotating disk plus a clamping
bolt and a clamping handle.
[0007] In this manner, all of the directions of movement can be
fixed and released again with a single clamping handle, the
clamping action is stronger and the mounting task and the number of
components are reduced.
[0008] As to what concerns stability, it is advantageous if the
gripper clamp can be is closed with an insertable clamping wing. To
ensure full flexibility of the sun and weather protection device it
is of further advantage if the support rod is slidingly movable in
its axial direction when the clamping screw is released. It is
advantageous if the rotating disks for adjusting the angle between
the standing rod and the support rod comprise mutually engaging
indentations so as to achieve a form-locking connection.
Alternatively, the rotating disks for adjusting the angle between
the standing rod and the support rod can also be conically
shaped--in order to establish a force-fitting connection.
[0009] Advantageously, the support rod and also the standing rod
are configured with tubular shapes. In order to increase stability
the support rod--as well as the standing rod--can have an outer
cross section deviating at least sectionwise from a circular outer
cross section, with one hinge part comprising in its gripper clamp
part adaptor elements to said outer cross section. For this
purpose, oval or polygonal outer cross sections with or without
rounded corners are advantageous. But it is also possible to use a
support rod--as well as a standing rod--comprising at least
sectionwise a longitudinal groove, in which case at least one hinge
part comprises, in its gripper clamp part, adaptor elements for the
longitudinal groove. To provide for a height adjustment of the sun
and weather protection device, the standing rod can comprise at
least two telescopically sliding profiles.
[0010] To increase the stability and to improve the operation,
mutually overlapping centering sleeves can be arranged around the
center of the rotating disks.
[0011] The aforementioned elements as well as those claimed and
described in the following exemplary embodiments, to be used
according to the invention, are not subject to any particular
conditions by way of exclusion in terms of their size, shape, use
of material and technical design, with the result that the
selection criteria known in the respective field of application can
be used without restrictions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] The parasol shown in FIGS. 1 to 3 and denoted as a whole as
2 comprises a standing rod 4 which in the present exemplary
embodiment comprises two pipe parts 6 and 8 that are telescopically
sliding into each other and which can locked and released with a
first attachment device 9 provided with a first clamping handle
10.
[0021] At the upper end of the upper pipe part 8 there is arranged
a hinge 20 according to a preferred exemplary embodiment of the
present invention. Moreover, the parasol of FIG. 1 comprises a
support rod 22 which is depicted for the case of a horizontal
orientation and which is also arranged at the hinge 20.
[0022] In FIG. 4 there is shown the hinge 20 which receives, on the
one hand, the standing rod 4, namely the upper pipe part 8 of the
standing rod, and, on the other hand, the support rod 22, both of
which are slidable when the clamping handle 40 is released and both
of which are locked when the clamping handle 40 of the hinge 20 is
locked. Basically the hinge 20 of this exemplary embodiment
comprises four functions which are all enabled when the clamping
handle 40 is released and which all are prevented when the clamping
handle 40 is locked, namely. The rotatability A of the standing rod
4 about the hinge 20, the slidability B of the support rod 22 in
the hinge 20, the rotatability C of the support rod 22 about its
own axis in the hinge 20 and also the rotatability D of the support
rod 22 about the standing rod 4--in the exemplary embodiment by
means of form-fitting indentations in two rotating disks 42 and 44
in the locked state. In an alternative exemplary embodiment--which
is not shown separately the locking of the rotatability of the
support rod 22 against the standing rod 4 is provided in a
force-fitting manner preferably by having the rotating disks 42 and
44 for adjusting the angle between the standing rod 4 and the
support rod 22 to be conically shaped. In a further alternative
exemplary embodiment--which is not shown separately--the locking of
the rotatability of the support rod 22 against the standing rod 4
is provided as a mixed form- and force-fitting type by having the
rotating disks 42 and 44 configured with a roughened surface.
[0023] Due to the fact that in the proposed embodiment the hinge is
configured with two hinge halves with closed gripper clamps and
with two toothed rotating disks 42, 44 or in the above mentioned
alternative embodiment, with conical or roughened-surface rotating
disks, respectively - and further with clamping bolts 46 and a
clamping handle 40, all of the directions of movement can be fixed
and released again with a single clamping handle 40. The clamping
action is stronger and the mounting task and the number of
components are reduced. In the present exemplary embodiment, the
hinge 40 thus comprises substantially two hinge halves in the form
of rotating disks 42 and 44 with integrated gripper clamps 43, 45
and a clamping bolt 46. In the exemplary embodiment shown, the
support rod 22 as well as the standing rod 4 have a circular outer
cross section. In alternative exemplary embodiments, the support
rod 22 and/or the standing rod 4 have an outer cross section
deviating therefrom. To nonetheless provide for rotatability of the
support rod 22 or the standing rod 4, the respective hinge part
comprises. In its gripper clamp part, adaptor elements to said
outer cross section. For this purpose, one can use an outer cross
section that is at least sectionwise oval or a polygonal outer
cross section with or without rounded corners, or a support rod
and/or standing rod can be inserted which comprises at least
sectionwise a longitudinal groove. In the exemplary embodiment as
shown in FIG. 5, mutually overlapping centering sleeves 48 and 49
are arranged around the center of the rotating disks 42 and 44.
[0024] At both ends of the support rod 22, there are short support
struts 24, 24a articulately attached opposite to each other with
one end thereof, and with the other end thereof connected to hinges
in the central part of long tensioning struts 26, 26a. The long
tensioning struts 26, 26a are articulately connected at one end
thereof with slides 28 running on the support rod 22, whereas at
the outer ends of the tensioning struts 26, 26a there are attached
the corners 30, 30a of the flexible protecting surface 32. The two
slides 28 which are slidable in opposite directions and are
equipped with a spring-loaded tilting lever 29 having claws that
engage into a catch when the roof is open. Upon actuating the
tilting lever 29, the sliders 28 are again released and can be
slidingly pushed back. This arrangement of the struts 24, 24a, 26,
26a have the effect that the ends of the tensioning struts 26, 26a,
which are connected with the corners 30, 30a of the protecting
surface 32, move almost perpendicularly and linearly with respect
to the support rod 22 and that the protecting surface 32 is brought
to a parallel folding 33, thus allowing for unimpeded operation of
the hinge 20 also when the roof is closed. Advantageously, the long
tensioning struts 26,26a are arranged in such manner that in their
folded position the outer ends thereof are arranged in a recessed
position relative to the ends of the support rod 22, so as to avoid
excessive stretching of the protecting surface 32 upon opening or
closing operation.
[0025] In the exemplary embodiment shown, the protecting surface 32
comprises corners 30, 30a, the corners 30, 30a of the protecting
surface 32 being rotatably mounted at the ends of the struts. The
support rod 22 comprises guiding grooves 34 for preventing twisting
of the slides 28. In the guiding grooves 34 of the support rod 22
there are arranged stopper pawls 35 for the end position of the
slides 28. For opening and closing, a tilting lever 29 with claws
29a provided with a spring is arranged in each of the slides 28
which holds the open tensioning struts 26, 26a in position by
engaging with a counter catch at the support rod 22. The long
tensioning struts 26, 26a are provided with spring-loaded
extensions for compensating tension. The outer ends of the long
tensioning struts 26, 26a in their closed position are arranged in
a recessed position relative to the ends 22a of the support rod so
as to avoid an excessive stretching of parts of the protecting
surface 32. In the present exemplary embodiment, the struts are
provided with spreading springs (alternatively: with spacers).
Moreover, the protecting surface 32 comprises additional
attachments 25 to the support rod 22 at one or both sides of the
adjusting hinge, the support rod being provided in each case with a
protection ring 25a.
