BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to improvements in support apparatus for covers and, more particularly, but not by way of limitation, to an awning control apparatus for connection to a support structure.
2. 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 drilling impetus to roll and unroll the awning, but also provides the driving impetus to move the support connectors 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 still further object of the invention is to provide an awning control apparatus wherein the support connectors provide rigid support for the awning, yet wherein each support connector is readily adjustable to a storing position and to an operating position.
One other object of the invention is to provide an awning control apparatus which can be economically and efficiently supported on a camper-type trailer support structure.
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 the various embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
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-type 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 14 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 removably and securedly connected to the support structure 12 via a bar 26, as shown more clearly in FIGS. 5 and 6. As shown in FIGS. 4 and 5, the bar 26 has a hollow portion 28 formed therethrough, and an elongated slot 30 which intersects the hollow portion of the bar 26 and extends between the opposite ends of the bar 26.
As shown more clearly in FIG. 5, a portion of the awning 14, generally near support end 22 thereof, is rolled over a stranded, rope-like member 32 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 32, is sized to be removably and slidably disposed in the hollow portion 28 of the bar 26. The slot 30 of the bar 26 has a width smaller than the diameter of the hollow portion 28, and is sized such that, in an assembled position, as shown in FIGS. 5 and 6, the awning 14 extends generally through the slot 30. In this position, the ridged portion of the awning 14 formed by the rope-like member 32 engages a portion of the bar 26 generally adjacent the slot 30, the bar 26 thereby securedly connecting the awning 14 to the support structure 12.
The awning control apparatus 10 also includes a drive assembly 34, which is connected to the shaft 18, to rotate the shaft 18 in a storing direction 36, as shown more clearly in FIG. 2, to storingly roll the awning 14 about the shaft 18. The drive assembly 34 is also constructed to rotate the shaft 18 in a releasing direction 38 to releasingly unroll the awning 14 from the shaft 18. It will be apparent to those skilled in the art 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, the storing direction 36 and the releasing direction 38 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 drive assembly 34, as shown more clearly in FIGS. 2 and 3, includes a driven gear 40 which is securedly connected to one end of the shaft 18 and, more particularly, securedly connected to a shaft extension 42 which is partially disposed in the hollow portion of the shaft 18 and secured therein by a pin 34. As shown in FIG. 3, another shaft extension 42 is secured in the opposite end of the shaft 18 by another pin 34, a portion of each shaft extension 42 is bearingly connected to a support connector 46.
As shown more clearly in FIGS. 2 and 3, an endless chain drive 48 is connected to the driven gear 40 and to a drive gear 50 which is rotatingly supported on a portion of one of the support connectors 46 via a gear shaft 52, which is securedly connected to a portion of one of the connectors 46. The chain drive 48 thus provides the interconnection between the driven gear 40 and the drive gear 50.
As shown more clearly in FIG. 3, a portion of the gear shaft 52 extends beyond the driven gear 50, and a hand wrench assembly 54 is removably and securedly connected thereto. The hand wrench assembly 54 is connected to the drive gear 50 such that an operator can rotate the drive gear 50 by gripping and rotatingly turning the hand wrench assembly 54. The rotating motion of the drive gear 50 is translated to the driven gear 40 via the chain drive 48, the shaft 18 being thus rotated by imparting rotating motion to the hand wrench assembly 54.
As mentioned before, the awning control apparatus 10 includes a pair of support connectors 46 and, as shown more clearly in FIG. 2, each support connector 46 includes a hollow base member 56 having one end thereof pivotally connected to a portion of the support structure 12 via a pin 58, as shown in detail in FIG. 8. The pin 58 is connected to a portion of the support structure 12 via a pair of L-shaped flange members 60.
As shown in FIG. 2, each support connector 46 also includes a rod member 62, having a portion thereof telescoped in a portion of the hollow portion of the base member 56, through one end of the base member 56, opposite the end of thereof which is pivotally connected to the support structure 12. The base member 56 and the rod member 62 are each constructed such that the rod member 62 can be telescoped in a generally downwardly direction 64 and in a generally upwardly direction 66 within the hollow portion of the base member 56, for reasons which will be made more apparent below.
As shown more clearly in FIG. 9, the support assembly 16 also includes a pair of screw members 68, each screw member 68 being threaded through a portion of one of the base members 56. The screw members 68 are sized such that each screw member 68 can be threaded through one of the base members 56, to a position wherein a portion of each screw member 68 intersects the hollow portion of one of the base members 56 and engages an adjacent portion of one of the rod members 62 to secure that rod member 62 in predetermined telescoped positions within the base member 56, for reasons which will be made more apparent below.
As shown more clearly in FIGS. 2 and 3, a stop 70 is secured to a portion of each rod member 62. Each stop 70 is sized and positioned such that a lower portion thereof engages the end of one of the base members 56, opposite the end of the base member 56 which is pivotally secured to the support structure 12, to limitingly position each rod member 62 in a storing position within one of the base members 56, for reasons which will be made more apparent below.
As shown in FIG. 2, the support assembly 16 also includes a pair of brace members 72 (only one of the base members being shown in FIG. 2). Each brace member 72 has one end which is pivotally connected to a portion of the support structure 12 via a pin 74 and an L-shaped flange 76, each flange 76 being secured to the support structure 12, as shown more clearly in FIGS. 4 and 6. The end of each brace member 72, opposite the end thereof which is pivotally secured to the support structure 12, is removably connected to one of the support connectors 46 and, more particularly, to one of the base members 56. Each brace member 72 is pivotably to a bracing position, as shown in FIGS. 2, 9 and 10, with respect to one of the support connectors 46, to prevent the rotation of the support connectors 46 in a direction generally toward the support structure 12, for reasons which will be made more apparent below.
As shown more clearly in FIGS. 9 and 10, a C-shaped member 78 is removably secured to the end of each brace member 72, opposite the end thereof which is pivotally secured to the support structure 12, via a fastener 80. In one form, each C-shaped member 78 may be constructed of an elastomeric material to reduce sliding friction between each C-shaped member 78 and the base member 56 in engagement therewith.
As shown in FIGS. 1 and 2, and as shown more clearly in FIG. 7, the awning control apparatus 10 also includes a pair of C-shaped flanges 86, each C-shaped flange 86 being secured to a portion of the support structure 12 and positioned thereon to receive one of the brace members 72 and one of the support connectors 46, in one position of each brace member 72 and each support connector 46. The support assembly 16 is constructed and positioned on the support structure 12, such that each brace member 72 and each support connector 46 can be pivoted in a direction generally toward the support structure 16 to a stored position (shown in dashed-lines in FIG. 2), wherein each base member 72 and each support connector 46 is disposed generally adjacent the support structure 12 and removably disposed in one of the C-shaped flanges 86. Each brace member 72 and each support connector 46 is secured in a stored position within one of the C-shaped flanges 86 by a pin 88.
Operation of FIGS. 1 through 10
The awning control apparatus 10, described in detail above, is constructed to controllingly and uniformly unroll the awning 14 from 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 about the shaft 18 and to move the awning control apparatus 10 to a stored position, the operator will initially disengage each brace member 72 from the support connectors 76, and pivot each brace member 72 in a general direction 90 toward the support structure 12, to a position wherein each brace member 72 is disposed generally adjacent the support structure 12. The operator will then disengage each screw member 68 from the respective rod member 62 in engagement therewith, and telescope each rod member 62 in a generally downwardly direction 64, to a position wherein the stop 70 connected to each rod member 62 limitingly engages one of the base members 56, thereby positioning each support connector 48 in a position to be storingly disposed with respect to the support structure 12.
The operator will then secure the hand wrench assembly 54 to the end of the gear shaft 52, opposite the end thereof rotatingly disposed through one of the rod members 62. The operator will then rotate the hand wrench assembly 54 in a direction of rotation causing the shaft 18 to be rotated in a storing direction 36.
As the shaft 18 is rotated in a storing direction 36, the awning 14 will be storingly rolled about the shaft 18, thereby moving the shaft 18 and pivotally moving each support connector 46 in a general direction 92, generally toward the support structure 12. In the extended position of the awning 14, as shown in FIGS. 1 and 2, each support connector 46 is disposed such that the natural gravitational forces tend to pivot each support connector 46 in a general direction 94. The pivotal movement of each support connector 46 in a general direction 94 is limited by the awning 14 which is secured to the support structure 12 and to the shaft 18.
The pivotal tendency of each support connector 46 in the general direction 94 causes the weight of each support connector 46 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 taught 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.
When the awning 14 has been storingly rolled about the shaft 18, each support connector 46 and the shaft 18 will have been pivoted in a general direction 92 to a stored position, generally adjacent the support structure 12, as shown in dashed-lines in FIG. 2. In this position, each brace member 72 is interposed between one of the support connectors 46 and the supported structure 12, and each brace member 72 and each support connector 46 is so disposed on one of the C-shaped flanges 86, as shown in FIGS. 2 and 7. The pins 88 are then each inserted through each C-shaped flange 86, to secure the brace members 72 and the support connectors 46 in a stored position.
To position the awning 14 in the extended position as shown in FIGS. 1 and 2, the operator will initially remove each pin 88 from the C-shaped flanges 86, and connect the hand wrench assembly 54 about the gear shaft 52, in a manner as described above. The operator will rotate the hand wrench assembly 54 in a direction causing the shaft 18 to be rotated in a releasing direction 38, thereby releasingly unrolling the awning 14 from the shaft 18.
As the awning 14 is releasingly unrolled from the shaft 18, each support connector 46 and the shaft 18 connected thereto will be pivoted in a direction 94, to a position wherein the awning 14 is completely unrolled from the shaft 18 and in a fully extended position, similar to the position of the awning 14 as shown in FIGS. 1 and 2. The operator will then telescope each rod member 62 in a general direction 66, to a position wherein the awning 14 is extended in a generally horizontal plane above the ground as shown in FIGS. 1 and 2. The screw members 68 are then threaded through each of the base members 56, to secure each rod member 62 in an assembled position with respect to each base member 56.
Each brace member 72 is then pivoted in a general direction 96, to a position wherein each C-shaped engaging member 78 engages a portion of one of the base members 56, thereby preventing the pivotal movement of each base member 56 in a general direction 92, as mentioned before.
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 position relative to the support structure 12.
Embodiment of FIGS. 11 and 12
The awning control apparatus 10a, shown in FIGS. 11 and 12, is constructed similar to the awning control apparatus 10, described before, the salient difference being that the awning control apparatus 10a includes a modified drive assembly 34a. More particularly, the drive assembly 34a includes an electric motor 100 which is gearingly connected to one of the shaft extensions 42 via a gear box 102. As shown in FIGS. 11 and 12, the motor 100 is secured to one of the rod members 62 and supported in an assembled position thereby.
In this embodiment of the invention, the motor controls (not shown) can be remotely disposed with respect to the drive assembly 34a, and thus the awning control apparatus 10a can be operated from a remote position in a manner reducing the amount of physical exertion expended by the operator in moving the awning 14 to a storingly rolled or an extended position, as described before.
Operation of FIGS. 11 and 12
The awning control apparatus 10a, shown in FIGS. 11 and 12, will operate substantially the same as the awning control apparatus 10, described before. The salient difference with respect to the operation of the awning control apparatus 10a will be that the driving impetus to rotate the shaft 18 in a storing direction 36 or a releasing direction 38 is the motor by themotor 100. Since the motor 100 rotates at relatively constant speed, the utilization of the motor 100 will result, not only in an increase in efficiency of operation, but also will substantially increase the uniformity with which the awning 14 is storingly rolled or unrolled about the shaft 18. It should also be noted that the motor 100 can be easily stopped to position the awning 14 at various intermediate positions between the stored position and the extended position thereof, if desired in some applications.
Embodiment of FIGS. 13 and 14
The awning control apparatus 10b, shown in FIGS. 13 and 14, is constructed similar to the awning control apparatus 10, described before, the salient difference being that the awning control apparatus 10b includes a modified drive assembly 34b. The drive assembly 34b, more particularly, includes an adapter 104 which is secured to one of the shaft extensions 42, as shown more clearly in FIG. 13. The adapter 104 is constructed to removably receive the hand wrench assembly 54, in a manner similar to that described before with respect to the awning control apparatus 10.
Operation of FIGS. 13 and 14
The awning control apparatus 10b, shown in FIGS. 13 and 14, will operate substantially the same as the awning control apparatus 10, described before, the salient difference being that the driving impetus to rotate the shaft 18 is provided by a modified drive assembly 34b. More particularly, the hand wrench assembly 54 is directly connected to the shaft 18 via the adapter 104 and the shaft extension 42, thereby eliminating the need for providing the gears and chain drives, similar to the gears and chain drives of the drive assembly 34, described before. The awning control apparatus 10b can thus be constructed in a less costly manner and may be desirable in some applications, particularly smaller sizes of the awning control apparatus.
Changes may be made in the construction and arrangement of the parts or the elements of the various embodiments as dieclosed herein without departing from the spirit and the scope of the invention as defined in the following claims.
