Description
BACKGROUND OF THE INVENTION
This invention relates generally to improvements in awning control
apparatus, and, more particularly, but not by way of limitation, to
awning control apparatus for connection to a support structure
having a motor supported in a portion of the awning shaft connected
to roll and unroll the awning about a shaft.
DESCRIPTION OF THE PRIOR ART
In the past, various support devices have been developed for
supporting an awning in a fully extended position, in a horizontal
plane generally above the ground. Some of these support devices
have been adapted to be utilized in cooperation with various
support structures.
In the past, these supports have generally comprised a plurality of
support legs, which were secured to one end of the awning and
supported in the ground. The end of the awning opposite the end
thereof secured to the support legs was generally attached to the
support structure. In this type of support apparatus, it was
generally necessary to disconnect the awning from the support legs,
remove the support legs to a remote storing location, and roll the
awning in some manner to be storingly supported on the support
structure. In some instances, the awning was completely
disconnected from the support structure, rolled and then
stored.
SUMMARY OF THE INVENTION
An object of the invention is to provide an awning control
apparatus for supporting an awning in an extended position relative
to a support structure which is economical in construction and
operation.
Another object of the invention is to provide an awning control
apparatus wherein the drive means not only provides the driving
impetus to roll and unroll the awning, but also provides the
driving impetus to move the support connection to a stored and an
operating position, respectively.
A further object of the invention is to provide an awning control
apparatus wherein the awning is rolled and unrolled about a shaft
in a more uniform and efficient manner.
A an further object of the invention is to provide an awning
control apparatus which can be economically and efficiently
supported on a camper-type trailer or mobile home support
structure.
One other object of the invention is to provide a drive means for
an awning control assembly which is substantially protected from
the elements during the operation thereof.
Other objects and advantages of the invention will be evident from
the following detailed description when read in conjunction with
the accompanying drawings which illustrate one preferred embodiment
of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings in general, and to FIG. 1 in particular,
shown therein and designated by the general reference numeral 10 is
an awning control apparatus which is connected to a support
structure 12, or, more particularly, connected to a camper-trailer
12. The awning control apparatus 10 is constructed to move an
awning 14 to a stored position and to an extended, assembled
position, and to support the awning in these positions. The awning
control apparatus 10 includes a support assembly 16, which is
connected to the awning 14 via a shaft 18, and to the support
structure 12 such that the awning control apparatus 10, including
the support assembly 16, is pivoted to a stored position and an
operating position as the awning 14 is rolled and unrolled,
respectively, about the shaft 18, in a manner to be described in
detail below.
The awning 14 is constructed of a relatively flexible material and
has a roll end 20 and a support end 22. The roll end 20 is
securedly connected to the shaft 18 via a plurality of rivets 24,
as shown more clearly in FIG. 3.
The support end 22 of the awning 14 is connected to the support
structure 12 via a bar 26. In one form, the support end 22 of the
awning 14 is removably secured to the support structure 12 and, in
this form, the bar 26 includes a hollow portion extending axially
therethrough and an axially extending elongated slot which
intersects the hollow portion of the bar 26 and extends between the
opposite ends of the bar. In this embodiment of the invention, a
portion of the awning 14, generally near the support end 22
thereof, is rolled over a stranded, rope-like member and secured
thereabout to form a ridge extending generally along the support
end 22 of the awning 14. The ridged portion of the awning 14,
formed by the rope-like member, is sized to be removably and
slidably disposed within the hollow portion of the bar 26, in a
manner described in detail in the applicants' copending
application, Ser. No. 108,880, filed Jan. 22, 1971.
The awning control apparatus 10 also includes a drive assembly 28,
which is secured to a portion of the shaft 18, to rotate the shaft
18 in a storing direction 30, as shown more clearly in FIG. 2, to
storingly roll the awning 14 about the shaft 18. The drive assembly
28 is also constructed to rotate the shaft 18 in a releasing
direction 32 to releasingly unroll the awning 14 from the shaft 18.
It will be apparent from the foregoing and from the detailed
description below, that since the roll end 20 of the awning 14 is
secured to the shaft 18 via the rivets 24, the storing direction 30
and the releasing direction 32 are, more particularly, relative
directions. The shaft 18 can thus be rotated clockwise or
counterclockwise to storingly roll the awning 14 thereabout, the
releasing direction of rotation in either event being generally
opposite the storing direction of rotation.
The shaft 18 is generally cylindrically shaped and has an opening
34 extending axially therethrough intersecting the opposite ends 36
and 38 of the shaft 18, as shown more clearly in FIG. 3. The
opening 34 is sized to receive a portion of the drive assembly 28,
in a manner and for reasons to be made more apparent below.
The drive assembly 28 includes a motor 40, having a motor housing
41 enclosing the various operating components thereof and a drive
shaft 42 journally extending through the housing 41 a predetermined
distance from one end of the motor 40. The motor 40 is connected to
a motor power source 44 via a cable 46. A motor control 48 is
interposed between the motor power source 44 and the motor 40, the
motor control 48 being positionable in a forward position, a
reverse position and an off position in one preferred operational
embodiment. The motor control 48 is constructed to establish
continuity between the motor 40 and the motor power source 44 in
the forward and the reverse positions thereof, and to interrupt
continuity therebetween in the off position thereof. The motor 40
is constructed to drivingly rotate the drive shaft 42 in one
direction substantially corresponding to the storing direction 30
when the motor control 48 is positioned in the forward position,
and to drivingly rotate the drive shaft 42 in an opposite direction
substantially corresponding to the releasing direction 32 when the
motor control 48 is positioned in the reverse position.
In one preferred form, the motor 40 is, more particularly, an
electric motor and is connected to a source of electrical energy
represented via the motor power source 44 by electrical conductors
comprising the cable 46. In this embodiment, the motor control 48
is a "forward-off-reverse" bi-polarity type of three-position
switch, for example, capable of establishing electrical continuity
between the motor 40 and the motor power source 44 in the forward
position of the motor control 48 with reverse polarity as compared
to the polarity of the motor power source 44 when connected to the
motor 40 in the reverse position of the motor control 48. Electric
motors having drive shafts and constructed to be operated via a
"forward-off-reverse" switch type of motor control interposed
between the motor and an electrical power source are well-known in
the art and a detailed description of the construction and the
operation of the motor, the drive shaft and the switch-type of
motor control is not required herein.
The motor 40 is disposed within the opening 34 of the shaft 18
generally near the end 36 of the shaft 18 and, more particularly,
the motor 40 is securedly connected to the shaft 18 via securing
bolts 50 threadably inserted through threaded apertures 52 formed
through the shaft 18, one end of each of the securing bolts 50
engaging the motor housing 41 and cooperating to secure the motor
40 in an assembled position connected to the shaft 18. The motor 40
is positioned near the end 36 of the shaft 18 such that, in an
assembled position, the drive shaft 42 extends axially a
predetermined distance beyond the end 36 of the shaft 18.
A circular cap 54, having a cap opening 56 formed through a central
portion thereof, is removably connected to the end 36 of the shaft
18, more particularly, the cap 54 has a flange 58 formed on the
outer periphery thereof extending a predetermined distance
generally perpendicularly therefrom and circumferentially
thereabout. The outer diameter of the cap 54 formed via the outer
peripheral surface of the flange 58 is slightly less than the inner
diameter of the axial opening 34 of the shaft 18. In an assembled
position, the flange 58 of the cap 54 is inserted a distance into
the opening 34 of the end 36 of the shaft 18 to a position wherein
the cap 54 is removably secured to the shaft 18 and the drive shaft
42 extends through the cap opening 56.
In one preferred embodiment, the flange 58 is sized to sealingly
engage the wall formed in the shaft 18 via the axial opening 34. In
this last-mentioned embodiment, the outer diameter of the cap 54
formed via the outer peripheral surface of the flange 58 is sized
to provide a "press fit" or the like, sealingly engaging the inner
peripheral surface formed via the axial opening 34 in the shaft 18,
for example.
A cylindrically shaped plug 60 is disposed within the axial opening
34 generally near the end 38 of the shaft 18. A shaft extension 62
is connected to one end of the plug 60 and extends a predetermined
distance axially from the central portion of the plug 60. In an
assembled condition, the plug 60 is disposed within the opening 34
and positioned therein such that the shaft extension 62 extends a
predetermined distance axially beyond the end 38 of the shaft 18.
The plug 60 is secured within the shaft 18 via a securing bolt 64
threadably inserted through a threaded aperture 65 formed through a
portion of the shaft 18 and intersecting the opening 34 generally
near the end 38 of the shaft 18. The securing bolt 64 engages the
shaft 18 and the plug 60 securing the plug 60 in an assembled
position connected to the shaft 18.
The support assembly 16 includes a pair of support connectors 66
and 68 (the support connectors 66 and 68 sometimes being referred
to below as the first support connector 66 and the second support
connector 68). The drive shaft 42 of the motor 40 is secured to the
support connector 66 and the shaft extension 62 is journally
connected to the support connector 68. Thus, in a driven position
of the motor 40 when the motor control 48 is positioned in the
forward or the reverse position, torque is applied at the drive
shaft 42 via the motor 40 causing the motor 40 to rotate relative
to the support connector 66 since the drive shaft 42 is secured to
the support connector 66. The rotation of the motor 40 is imparted
to the shaft 18 due to the connection between the shaft 18 and the
motor 40 provided via the securing bolts 50, the end 38 of the
shaft 18 being journally connected to the support connector 68 via
the shaft extension 62 journally connected to the support connector
68. The direction of rotation of the shaft 18 is controlled via the
position of the motor control 48 in a manner described before.
The support connectors 66 and 68 are each constructed similarly and
each support connector 66 and 68 includes a rod member 70, having
one end thereof pivotally connected to a portion of the support
structure 12 via a rod member pin 72 journally connected to and
supported by a flange member 74 and a hollow base member 76, each
base member 76 having a portion telescoped about a portion of one
of the rod members 70. Each base member 76 is, more particularly,
telescoped about the end of one of the rod members 70, opposite the
end of the rod member 70 pivotally connected to the support
structure 12, the rod members 70 each being telescoped in a portion
of the hollow portion of one of the base members 76. The rod member
70 and the base member 76 of each support connector 66 and 68 are
each constructed such that the base members 76 can be telescoped
about one of the rod members 70 in a generally downwardly direction
78 and in a generally upwardly direction 80, for reasons which will
be made more apparent below.
The support assembly 16 also includes a pair of screw members 82,
each screw member 82 having a portion threadedly insertable through
one of a plurality of threaded openings 83 formed in the base
members 76. The openings 83 are spaced along each base member 76
and the screw members 82 are sized such that each screw member 82
is removably insertable through one of the openings 83 in the base
members 76 to a position wherein a portion of each screw member 82
intersects the hollow portion of one of the base members 76. The
screw members 82 are, more particularly, positioned with the hollow
portions of the base members 76 such that a portion of each screw
member 76 engages an adjacent portion of one of the rod members 70
limiting the movement of the rod members 70 in a direction 80 and
securing each rod member 70 in a predetermined telescoped position
within one of the base members 76, the predetermined telescoped
position being selectively adjustable by inserting the screw
members 82 in selected openings 83, for reasons which will be made
more apparent below.
A stop 84 is disposed within the hollow portion of each of the base
members 76, each stop 84 being sized and positioned within one of
the base members 76 such that a lower portion thereof engages the
end of one of the rod members 70 telescoped in the base members 76
limiting the movement of each rod member 70 in a direction 80 and
positioning each rod member 70 in a storing position within one of
the base members 76, for reasons to be made more apparent
below.
The support assembly 16 also includes a pair of brace members 86.
One end of each brace member 86 is pivotally connected to a portion
of the support structure 12 via a pin 88 and a flange 90, each
flange 90 being secured to the support structure 12. The end of
each brace member 86, opposite the end thereof which is pivotally
secured to the support structure 12, is removably connected to one
of the support connectors 66 and 68 and, more particularly, to one
of the base members 76. Each brace member 86 is pivotable to a
bracing position, as shown in FIGS. 1 and 2, with respect to the
support connectors 66 and 68 to prevent the rotation of the support
connectors 66 and 68 in a direction generally toward the support
structure 12, for reasons to be made more apparent below.
A member 92 is removably secured to the end of each brace member
86, opposite the end thereof which is pivotally secured to the
support structure 12. In one form, each member 92 is constructed of
an elastomeric material to reduce sliding friction between each
member 92 and the base member 76 in engagement therewith.
The support assembly 16 also includes a pair of C-shaped flanges
94, each flange 94 being secured to a portion of the support
structure 12 and positioned thereon to receive one of the brace
members 86 and one of the support connectors 66 and 68, in one
position of each brace member 86 and each support connector 66 and
68. The support assembly 16 is constructed and positioned on the
support structure 12 such that each brace member 86 and each of the
support connectors 66 and 68 can be pivoted in a direction
generally toward the support structure 12 to a stored position
(shown in dashed-lines in FIG. 2), wherein each brace member 86 and
each of the support connectors 66 and 68 is disposed generally
adjacent the support structure 12 and removably disposed in one of
the C-shaped flanges 94. Each brace member 86 and each of the
support connectors 66 and 68 is secured in a stored position within
one of the C-shaped flanges 94 by a pin 96.
As shown more clearly in FIG. 3, a block 98 is disposed and secured
within the hollow portion of each base member 76 and disposed
generally near the ends thereof, opposite the end telescopingly
receiving one of the rod members 70. An opening 100 is formed
through each block 98 and, in an assembled position, each opening
100 is aligned with an opening 102 formed through each of the base
members 76.
The shaft extension 62, more particularly, journally extends
through the opening 102 in the base member 76 of the support
connector 68 and through the opening 100 formed through the block
98 secured within the base member 76 of the support connector 68.
The end of the shaft extension 62, opposite the end connected to
the plug 60, extends a distance beyond the base member 76 and a nut
104 is secured thereon, the nut 104 engaging the base member 76 and
retaining the shaft extension 62 in an assembled position journally
extending through the openings 100 and 102.
The drive shaft 42, more particularly, journally extends through
the opening 102 in the base member 76 of the support connector 66
and through the opening 100 formed through the block 98 secured
within the base member 76 of the support connector 66. The end of
the drive shaft 42, opposite the end extending from the motor
housing 41, also extends through a portion of an opening 106 formed

constructed to controllingly and uniformly unroll the awning 14
from about the shaft 18, to an extended or operating position, as
shown in FIGS. 1 and 2, and to securedly support the awning 14 in
that position. The awning control apparatus 10 also controllingly
and uniformly rolls the awning 14 about the shaft 18, to a position
wherein the awning control apparatus 10 is securedly supported in a
stored position (as shown in dashed-lines in FIG. 2).
To storingly roll the awning 14 about the shaft 18 and to move the
awning control apparatus 10 to a stored position, the operator will
initially disengage each brace member 86 from the support
connectors 66 and 68, and pivot each brace member 86 in a general
direction 114 toward the support structure 12, to a position
wherein each brace member 86 is disposed generally adjacent the
support structure 12 and within the flange members of the C-shaped
flanges 94. The operator will then disengage each screw member 82
from the respective rod member 70 in engagement therewith, and
telescope each base member 76 in a generally downwardly direction
78 to a position wherein each of the stops 84 limitingly engage the
end of one of the rod members 70, thereby positioning each of the
support connectors 66 and 68 in a position to be storingly disposed
with respect to the support structure 12.
The motor control 48 is then positioned in the forward position
establishing continuity between the motor 40 and the motor power
source 44 and positioning the motor 40 in a first driven position.
In the first driven position of the motor 40, torque is applied at
the drive shaft 42 in a direction causing the motor 40 and the
shaft 18 connected thereto to be rotated in a storing direction 30
via the interconnections between the motor 40 and the shaft 18 and
between the drive shaft 42 and the support connector 66.
As the shaft 18 is rotated in a storing direction 30, the awning 14
will be storingly rolled about the shaft 18 thereby pivotally
moving the shaft 18 and each of the support connectors 66 and 68 in
a general direction 116 toward the support structure 12. In the
extended position of the awning 14, each of the support connectors
66 and 68 and the shaft 18 are disposed such that the natural
gravitational forces tend to pivot the shaft 18 and each of the
support connectors 66 and 68 in a general direction 118, the weight
of the motor 40 supported within the shaft 18 augmenting the
pivotal movement in the direction 118. The pivotal movement of each
support connector 66 and 68 and the shaft 18 in a general direction
118 is limited by the awning 14 which is secured to the support
structure 12 and the shaft 18.
The pivotal tendency of each support connector 66 and 68 in the
general direction 118 causes the weight of each support connector
66 and 68 and weight of the shaft 18 to pull the awning 14 in a
direction generally away from the support structure 12, thereby
maintaining the awning 14 taut as the awning 14 is storingly rolled
about the shaft 18. In this manner, the awning 14 is rolled about
the shaft 18 in a more efficient and uniform manner. The motor
control 48, in one embodiment, may be of a variable speed type so
that the operator may regulate the speed with which the awning 14
is rolled and unrolled from about the shaft 18, however, in the
preferred embodiment, the motor 40 rotates the shaft 18 at a
relatively constant speed, the utilization of the motor 40
resulting not only in an increase in efficiency of operation, but
also substantially increasing the uniformity with which the awning
14 is storingly rolled or releasingly unrolled about the shaft
18.
It should also be noted that the motor 40 can be easily stopped to
position the awning 14 at various intermediate positions between
the extended position and the stored position thereof utilizing the
motor control 48, if desired, in some applications. In one
embodiment, the motor control 48 is remotely disposed with respect
to the motor 40 and the shaft 18 for operating the awning control
apparatus 10 from a remote position such as by locating the motor
control 48 inside the support structure 12 or on the exterior side
wall of the support structure 12 near the awning control apparatus
10, for example.
When the awning 14 has been storingly rolled about the shaft 18,
each of the support connectors 66 and 68 and the shaft 18 will have
been pivoted in a general direction 116 to a stored position,
generally adjacent the support structure 12, as shown in
dashed-lines in FIG. 2. In the storing position, each brace member
86 is interposed between one of the support connectors 66 and 68
and the support structure 12, and each brace member 86 and support
connectors 66 and 68 are so disposed in one of the C-shaped flanges
94, as shown in dashed-lines in FIG. 2. The pins 96 are then each
inserted through each flange 94 to secure the brace members 86 and
the support connectors 66 and 68 in a stored position.
To position the awning in the extended position as shown in FIGS. 1
and 2, the operator will initially remove each pin 96 from each
C-shaped flange 94 and position the motor control 48 in the reverse
position establishing continuity between the motor 40 and the motor
power source 44 positioning the motor 40 in a second driven
position. In the second driven position of the motor 40, torque is
applied at the drive shaft 42 in a direction causing the motor 40
and the shaft 18 connected thereto to be rotated in a releasing
direction 32 via the interconnections between the motor 40 and the
shaft 18 and between the drive shaft 42 and the support connector
66.
As the awning 14 is releasingly unrolled from the shaft 18, each
support connector 66 and 68 and the shaft 18 connected thereto will
be pivoted in a general direction 118, to a position wherein the
awning 14 is completely unrolled from the shaft 18 in the fully
extended position. As previously noted, the motor controls 48 may
interrupt continuity between the motor 40 and the power source 44
at any desired position of the awning 14 between the stored
position and the extended position, the natural gravitational
forces tending to pull the support connectors 66 and 68 and the
shaft 18 in a general direction 118 maintaining the awning 14
taut.
When the awning 14 has been unrolled to a predetermined, selected
position, the operator will then telescopingly extend each base
member 76 in a general direction 80, to a position wherein the
awning 14 is extended in a generally horizontal plane above the
ground, as shown in FIGS. 1 and 2. Each of the screw members 82 are
then threaded through one of the openings 83 in the base members 76
and positioned to securingly engage one of the rod members 70
securing each of the rod members 70 in an assembled position with
respect to one of the base members 76.
Each of the brace members 86 is then pivoted in a general direction
120 to a position wherein each member 92 engages a portion of one
of the base members 76, thereby preventing the pivotal movement of
the support connectors 66 and 68 and the shaft 18 in a general
direction 116 and securing the support assembly 16 in an assembled
position.
It will be apparent from the foregoing to those skilled in the art,
that the awning control apparatus 10, described above, is
constructed to uniformly roll and unroll the awning 14 in a more
efficient manner. The various components and assemblies of the
awning control apparatus 10 are constructed to cooperate in such a
manner that, as the awning 14 is moved to a rolled and an unrolled
position, each component and assembly is constructed and positioned
to be quickly, conveniently and efficiently secured in a stored or
extended position relative to the support structure 12. It should
also be noted that, since the motor 40 is enclosed via the shaft 18
and the cap 54, the motor 40 is substantially protected from the
elements during the operation of the awning control apparatus
10.
Changes may be made in the construction and arrangement of the
parts or elements of the embodiment as disclosed herein without
departing from the spirit and the scope of the invention as defined
in the following claims.
