canopy 20 can be controlled primarily by the movement of thearms 22. Eacharm 22 includes adistal end 22 a and aproximal end 22 b. For example, the distal ends 22 a of thearms 22 may be connected to thefront cover 18 such that, as thearms 22 extend or retract, thecanopy 20 is unwound or wound about the roller. As shown inFIG. 2 , theproximal end 22 b of eacharm 22 may be connected to ashoulder 34 that can be mounted on therack 14 and that allows the orientation of thearms 22 to be adjusted in a variety of ways as will be described below. It may be possible to connect only some of the proximal ends 22 b of thearms 22 to therack 14 using theshoulder 34 described herein. Therack 14 may include a rail 28 (FIG. 2 ) and theshoulder 34 may be affixed at any location along therail 28. Therack 14 may also provide achannel 15 in which thearms 22 can be placed in a stowed position of theawning 10. - As shown in
FIG. 3 , theshoulder 34 may include ajunction portion 36, abracket portion 38 and abase portion 40 which may be assembled to one another with screws or the like. It must be noted that other embodiments of theshoulder 34 may not include all of thejunction portion 36, thebracket portion 38 and thebase portion 40. - The
junction portion 36 may provide ahinge 42 at one of its longitudinal ends for connecting theproximal end 22 b of thearm 22 and thearm 22 may thus be rotatable about athird axis 44 that is substantially upright but slightly tilted from vertical. Moreover, thejunction portion 36 of theshoulder 34 may be rotatably adjustable so as to allow the pitch of thearms 22 to be adjusted. In this regard, a front interface of thebracket portion 38 may include a firstcurved surface 46 while a rear interface of thejunction portion 36 may include a secondcurved surface 48 that is shaped to correspond to the firstcurved surface 46. The firstcurved surface 46 may be a cylindrical concave surface while the secondcurved surface 48 may be a cylindrical convex surface. One of the firstcurved surface 46 and the secondcurved surface 48 may include one or more elongate beads 50 (FIG. 7A ) while the other of the firstcurved surface 46 and the secondcurved surface 48 may include a set ofgrooves 52 in which theelongate beads 50 can fit (FIG. 3 ). As shown inFIG. 6 , depending on the groove orgrooves 52 in which the elongate bead orbeads 50 are located in, the orientation of thejunction portion 36 relative to thebracket portion 38 will differ and rotatable adjustment of thejunction portion 36 with respect to thebracket portion 38 becomes possible. The embodiment ofFIG. 4 includes twoelongate beads 50 and fourgrooves 52 thus allowing thejunction portion 36 to assume three orientations about thebracket portion 38. Although not shown, an alternative embodiment of thejunction portion 36 including oneelongate bead 50 and four ormore grooves 52 would allow thejunction portion 36 to assume four or more orientations about thebracket portion 38. - The term “rotatable” is meant to describe that an object can be moved around an axis from a first point located at a given distance from the axis to a second point at the same distance from the axis and that the object moves through all points between the first point and the second point located at the same distance from the axis in order to move from the first point to the second point. The term “rotatably adjustable”, “rotatably adjusted” or “rotatable adjustment” is meant to describe that an object can be moved around an axis from a first point located at a given distance from the axis to a second point at the same distance from the axis but that the object does not move through all points between the first point and the second point located at the same distance from the axis in order to move from the first point to the second point.
- The
junction portion 36 can be described as being movable or rotatably adjustable because, at the different orientations assumed by thejunction portion 36, thejunction portion 36 is located at equal distances from a first axis 54 (FIG. 6 ) extending longitudinally about thejunction portion 36. However, thejunction portion 36 is not rotatable about thefirst axis 54 because such movement is not possible with abead 50 inside one of thegrooves 52. - The
shoulder 34 is provided with a mechanism to allow thejunction portion 36 to remain at an assumed orientation. As shown inFIGS. 7A-7B , theshoulder 34 may include arecess 56 on its front interface opposite the secondcurved surface 48 and afastening component 58 that can be inserted therein. For example, therecess 56 may be substantially semi-cylindrical and thefastening component 58 may include a curvedrear surface 59 a and a flatfront surface 59 b (FIGS. 7A-7B ). The inner perimeter of therecess 56 may correspond in shape to the outer perimeter of thefastening component 58 and thefastening component 58 may be perimetrically dimensioned to be at least partially insertable inside therecess 56. In this embodiment, the perimeter of thefastening component 58 is rectangular and at least the two longer edges of the rectangular perimeter of thefastening component 58 are in contact with the inner surfaces of therecess 56 when thefastening component 58 is secured to thejunction portion 36. Moreover, thefastening component 58 may include a set offirst holes 58 a and thejunction portion 36 may include a set ofsecond holes 36 a. Both thefirst holes 58 a and thesecond holes 36 a may be through holes. A set offirst screws 60 may be inserted through thefirst holes 58 a and thesecond holes 36 a and intoblind holes 62 formed on the firstcurved surface 46. Thesecond holes 36 a have elongate cross-section and are oriented to extend transversely about the elongate bead 50 (FIG. 7A ) and thefirst screws 60 are insertable along any part of thesecond holes 36 a. As a result, the orientation of thejunction portion 36 can be rotatably adjusted about thefirst axis 54 when thefirst screws 60 are loosened and thejunction portion 36 can be secured against thebracket portion 38 by tightening the first screws 60. The rotatable adjustment of thejunction portion 36 can change the pitch angle of thearms 22 when theawning 10 is extended. - Furthermore, the
shoulder 34 may be mounted to therail 28 through thebase portion 40 and the location of theshoulder 34 may be altered along therail 28 by sliding, for example. A rear interface of thebase portion 40 may be shaped correspondingly with therail 28 such that thebase portion 40 can be secured to therail 28. In this embodiment, the rear interface of thebase portion 40 includes a part with a C-shapedcross-section 64 that can grip and move along the rail 28 (FIG. 6 ). Thebase portion 40 may include throughholes 40 a (FIG. 5 ) at its bottom such that the location of thebase portion 40 can be fixed by way ofscrews 41 that can press against therail 28 once inserted fully (FIG. 6 ). - As shown in
FIG. 6 , thebracket portion 38 may be supported from underneath by thebase portion 40. Thebase portion 40 may include a front interface with a stepped configuration and thebracket portion 38 may include a rear interface with a steppedconfiguration 66 a corresponding to the steppedconfiguration 66 b of thebase portion 40 such that thebracket portion 38 can rest on thebase portion 40 and be supported from underneath. Moreover, thebracket portion 38 may be configured to be rotatably adjustable about thebase portion 40. For example, thebracket portion 38 may include a set of through holes extending through thebracket portion 38. These through holes may include athird hole 38 a with a circular cross-section and afourth hole 38 b with an elongate cross-section (FIG. 4 ). Thethird hole 38 a may be located on the opposite end of thehinge 42. A set ofsecond screws 66 may be inserted through thethird hole 38 a and thefourth hole 38 b and intoblind holes 68 formed on thebase portion 40 to secure thebracket portion 38 about thebase portion 40. Both thethird hole 38 a and thefourth hole 38 b may include a recess portion 38 c (FIG. 4 ) in which the head of thesecond screws 66 can be inserted. At the bottom of each of the recess portions 38 c, aflange 38 d (FIG. 4 ) against which the head of thesecond screw 66 can abut may be provided. When thesecond screws 66 in thethird hole 38 a and thefourth hole 38 b are loosened, thebracket portion 38 can rotate about asecond axis 70 extending through thethird hole 38 a while the unfilled part of thefourth hole 38 b, due to its elongate cross-section, may allow thebracket portion 38 to be rotatably adjusted about thebase portion 40. In this embodiment, thesecond axis 70 is substantially horizontal and is oriented to be perpendicular to the plane of interface of thebase portion 40 and thebracket portion 38. Thescrews 66 in the third andfourth holes bracket portion 38 is rotatably adjusted. The adjustment of thebracket portion 38 about thesecond axis 70 can be conducted by an adjustment feature provided at the bottom of thebase portion 40. The adjustment feature may include an adjustment hole 72 (FIG. 5 ) and an adjustment screw 74 (FIG. 3 ) inserted therein. Theadjustment hole 72 may be a threaded through hole. The end of theadjustment screw 74 opposite its head may be configured to push against a point that is located longitudinally midway on thebracket portion 38 such that tightening of thescrew 66 pushes thebracket portion 38 upward thereby resulting in counterclockwise rotation of thebracket portion 38 inFIG. 4 . Alternatively, loosening of thescrew 66 brings the intermediate part of thebracket portion 38 downward thereby resulting in clockwise rotation of thebracket portion 38 inFIG. 4 . Of course, theadjustment screw 74 would be easier to operate when thesecond screws 66 are loosened. - The above-described features of the
shoulder 34 allow the orientation of thearm 22 to be adjusted in a variety of ways. Rotatable adjustment of theshoulder 34 about thefirst axis 54 allows the pitch of thearm 22 to be adjusted in an extended state of thearm 22. Moreover, in the embodiment described herein, it is possible that the full retraction of thearm 22 does not bring the entirety of thearm 22 in a completely horizontal state so as to allow stowing of thearm 22 within thechannel 15 provided in therack 14 and this start to occur after extended use of thearm 22. In such a situation, it is necessary to re-orient thearm 22 to be horizontal and the ability to rotatably adjust thearm 22 about thesecond axis 70 can help resolve such an issue. - It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the claimed invention.
