DETAILED DESCRIPTION OF EMBODIMENT(S) OF THE INVENTION
The present invention will now be described in connection with one or more embodiments thereof. The discussion of the embodiments is not intended to be limiting of the present invention. To the contrary, any discussion of embodiments is intended to exemplify the breadth and scope of the present invention. As should be apparent to those skilled in the art, variations and equivalents of the embodiment(s) described herein may be employed without departing from the scope of the present invention. Those variations and equivalents are intended to be encompassed by the scope of the present patent application.
With reference to FIG. 1, the present invention is directed to the construction of a wind spinner 10 that may be deployed in a garden or other suitable location. In FIG. 1, the wind spinner 10 is depicted generically, without any specific shape or form. This depiction is intentional, as the wind spinner 10 may be constructed from any shape and may be provided with any surface indicia without departing from the scope of the present invention.
Specifically, as illustrated in FIGS. 6-12, the wind spinner 10 may be fashioned into any shape. The embodiments illustrated in FIGS. 6-12 are merely exemplary of the enormous variety of embodiments that comprise the present invention.
With continued reference to FIG. 1, the wind spinner 10 is contemplated to be mounted atop a stake 12 that may have a pointed end 14 for insertion into the ground 16. As should be apparent to those skilled in the art, however, the wind spinner 10 need not be constructed to be inserted into the ground 16. It is contemplated that the wind spinner 10 may be constructed so that it may be affixed to any suitable surface, as required or as desired. For example, the wind spinner 10 may be mounted in a bracket attached to a fixed surface.
Separately, it is contemplated that the wind spinner 10 may be secured from above. For example, the wind spinner 10 may hang from an overhead surface. In this alternative contemplated embodiment, the wind spinner 10 may be suspended from a suspensory device such as a rod, string, rope, chain, and/or wire, which is attached to the point above the wind spinner 10. If so, the wind spinner 10 is contemplated to rotate about the suspensory device in the direction of the arrow 20 in the same manner that the wind spinner 10 rotates about the stake 12. In this embodiment, the axis of rotation is defined by the suspensory device and is referred to as a suspensory axis.
Whether the wind spinner 10 rotates about a stake axis 22 or a suspensory axis, the axis of rotation is referred to herein as the rotation axis 22. The rotation axis 22, therefore, contemplates either mode of securement of the wind spinner 10, whether from below or from above.
As illustrated in the embodiments shown in FIGS. 1-11, the wind spinner 10 includes a body 18 that is contemplated to be pivotally mounted atop the stake 12. As a result, the body 18 is expected to rotate about the stake 12 in the direction indicated by the arrow 20. The body 18 is contemplated to pivot about the stake 12 in either rotational direction, without any bias for one direction over the other. As may be apparent, the body 18 is contemplated to move, like a weather vane, in response to forces applied by any wind impingent thereon.
In another contemplated embodiment, the wind spinner 10 may be constructed so that it rotates in only one direction consistent with the arrow 20.
Two rotating arms 24, 26 are pivotally connected to the body 18 such that they rotate about an axis 28 perpendicular to the axis 22. The axis 28 is shown more clearly in FIG. 2. The arm 24 is contemplated to rotate in a counterclockwise direction as indicated by the arrow 30. The arm 26 is contemplated to rotate in a clockwise direction as indicated by the arrow 32.
As should be apparent from the foregoing, in the embodiment of the wind spinner 10 that is depicted in FIG. 1, the arm 24 is contemplated to be mounted so that it exhibits a rotation opposite to that of the arm 26. In other words, the arm 24 is contemplated to counter-rotate with respect to the arm 26. It is contemplated, however, that the arms 24, 26 may be arranged so that they rotate in the same direction. In other words, the arms 24, 26 may co-rotate with respect to one another.
Each arm 24, 26 is provided with two blades 34, one at each end. The blades 34 are angled and positioned such that the blades 34 act similar to the blades on a propeller for an aircraft. The movement (or blowing) of wind 56 provides the motive force to rotate the blades 34 in the predetermined direction of rotation 30, 32. It is for this reason that the axis 28 also is referred to herein as the blade axis 28.
It is noted that one aspect of the wind spinner 10 of the present invention contemplates that the arms 24, 26 are positioned on opposite sides of the body 18. With reference to FIG. 1, the arms 24 is in front of the body 18 and the arm 26 is behind the body 18.
It is another aspect of the present invention that each arm 24, 26 is provided with a pair of blades 34, one at each end of the arms 24, 26. In alternate embodiments, it is contemplated that a plurality of arms 24, 26 may support a plurality of blades 34 without departing from the scope of the present invention.
As illustrated in FIG. 2, the wind spinner 10 is contemplated to include a stake pivot 44 that is mounted atop the stake 12. The stake pivot 44 permits the body 18 of the wind spinner 10 to rotate in the direction of the arrow 20, as discussed above. The construction of the stake pivot 44 is not critical to the operation of the present invention. Accordingly, further details concerning the construction of the stake pivot 44 are not provided herein.
A blade rod 46 extends through the stake pivot 44. The blade rod 46 extends outwardly from the stake pivot to the two arms 24, 26. The blade rod 46 supports the arms 24, 26 and defines the blade axis 28. As noted above, the arms 24, 26 rotate around the axis 28 in the directions of the arrows 30, 32.
A first blade pivot 48 and a second blade pivot 50 are disposed adjacent to either end of the blade rod 46. The blade pivots 48, 50 permit the arms 24, 26 to rotate around the blade rod 46 in the directions of the arrows 30, 32, as discussed above. So that the arms 24, 26 are retained on the blade rod 46, a first end cap 52 and a second end cap 54 are placed on the ends of the blade rod 46, as illustrated.
As should be apparent, the caps 52, 54 are not required to practice the present invention. The ends of the blade rod 46 may be fashioned such that the caps 52, 54 are not needed to retain the rods 36, 38 thereon.
It is noted that the rods 36, 38 may be unitary structures. In another contemplated embodiment, the rods 36, 38 may comprise two separate rods that connect to the blade pivots 48, 50. The exact construction of the rods 36, 38 is not critical to the construction of the wind spinner 10 of the present invention, as should be apparent to those skilled in the art.
As shown in FIG. 2, the rods 36, 38 provide the framework for the blades 34. As illustrated, the rods 36, 38 connect to the blade pivots 48, 50 at approximately a midpoint along the rods 36, 38. This assures that the rods 36, 38 are suitably balanced to facilitate rotation in the wind 56.
As noted above, the blades 34 are contemplated to respond to the wind 56. As such, the blades 34 are contemplated to be mounted on the rods 36, 38 so that the blades 34 are angled to the winds 56. In other words, the blades 34 are contemplated to be mounted to the rods 36, 38 at an angle. As a result, when the wind 56 blows, the blades 34 cause the arms 24, 26 to rotate.
So that the blades 34 retain their shape and angular orientation, the blades 34 incorporate a blade support 58 therein. The blade support 58 is contemplated to extend across the blades 34 and maintain the blades 34 in a suitable orientation (or angle of incidence) with respect to the wind 56 so that the blades 34 are animated by the wind 56.
FIG. 3 is an elevational, front view of one of the blades 34 on the arms 24, 26 of the wind spinner 10 of the present invention. The fabric 40 covering the blade 34 is shown in dotted line format. The blade support 58 is shown in larger detail in this view.
The blade support 58 is contemplated to extend across the blade 34 from one lateral side to the other. As such, the blade support 58 is contemplated to help maintain the blade 34 in a suitable angle and orientation during the operational lifetime of the wind spinner 10.
It is contemplated that the blade support 58 will be made from a suitable rigid material such as plastic. As should be apparent to those skilled in the art, however, any other suitable material may be employed without departing from the scope of the present invention. For example, the blade support may be made from metal, composite materials, etc.
The blade support 58 is contemplated to have a central portion 60, through which the rod 36 passes. Two wing elements 62 extend outwardly from the central portion 60, one from each side of the central portion 60. The wing elements 62 provide rigid stability to the construction of the blade 34 so that the blade 34 maintains a suitable angle and orientation for the operational lifetime of the wind spinner 10.
FIG. 4 is a cross-sectional view of the blade 34 illustrated in FIG. 3. The cross-section is taken along the line 4-4 in FIG. 3.
As illustrated in FIG. 4, the blade support 58 includes the central portion 60 through which the rod 36 passes. In the illustrated embodiment, the rod 36 has a square cross-section as does the opening through the central portion 60. The square cross-section of the rod 36 is intended to simplify manufacture of the wind spinner 10 of the present invention. Specifically, the rod 36 is contemplated to be mounted in the first blade pivot 48 at an angle such that, when the blade 34 is inserted through the rod 36, the blade 34 is at the correct angle and orientation.
FIG. 4 also illustrates one additional aspect of the blade 34 of the present invention. Specifically, the shell of the blade 34 includes two layers. The outer layer is the fabric layer 40, as discussed above. While the fabric layer 40 may have sufficient rigidity to be employed by itself as the covering for the blade 34, it is contemplated that the fabric 40 may benefit from a reinforcing layer of plastic 64 thereunder. As such, in the embodiment illustrated in FIG. 4, the surface of the blade 34 includes an outer fabric layer 40 and an inner plastic layer 64.
The inner plastic layer 64 is contemplated to be made from a transparent plastic or other suitable material. Being transparent, the inner plastic layer 64 should not alter the exterior appearance of the wind spinner 10, even when subjected to strong sunlight conditions. While a transparent plastic is contemplated for the plastic layer 64, any suitable alternative may be employed without departing from the scope of the present invention.
As also illustrated in FIG. 4, the stitching 42 for the blade 34 is contemplated to pass through the fabric layer 40 and the plastic layer 64 on both sides of the blade 34, thereby securing the sides of the blade 34 to one another. The stitching 42 also is contemplated to pass through the wing elements 62, as shown in FIG. 4. As such, the various structures that form the blade 34 are secured to one another.
FIG. 5 is a cross-sectional view similar to the view provided in FIG. 4. FIG. 5, however, presents a variation of the embodiment illustrated in FIG. 4.
FIG. 5 presents an embodiment of the blade 34 where the central portion 60 is attached to the wing portions 62 in an offset arrangement. In addition, the opening through which the rod 36 passes is disposed at an angle to the exterior surface of the central portion 60. The angular displacement establishes an angle Φ that is suitable to establish an angle of incidence for the wind 56.
As should be apparent, in the embodiment illustrated in FIG. 4, the angle of incidence Φ to the blade 34 is established by the angle of the opening through the first blade pivot 48. In the embodiment illustrated in FIG. 5, the angle of incidence to the blade 34 is established by the angle Φ in the central portion 60.
While FIGS. 4 and 5 illustrate two embodiments for the blades 34 on the wind spinner 10 of the present invention, other variations may be employed without deviating from the scope of the present invention.
FIGS. 6-12 illustrate several additional embodiments of the wind spinner 10 of the present invention.
In particular, FIG. 6 illustrates a second embodiment of a wind spinner 66 according to the present invention. The wind spinner 66 is designed to appear as a kayaker rowing his kayak. As such, the blades 34 of the wind spinner 66 are shaped to appear like the paddle portions of oars for the kayak.
FIG. 7 illustrates a third embodiment of a wind spinner 68 according to the present invention. This embodiment is a stylized depiction of Uncle Sam. For this wind spinner 68, the arms of Uncle Sam are the blades 23 that rotate in the wind 56.
FIG. 8 is an illustration of a fourth embodiment of a wind spinner 70 according to the present invention. In this embodiment, the body 18 of the wind spinner is in the shape of a hummingbird. The wings of the hummingbird are the blades 34 that move in response to the wind 56.
FIG. 9 is an illustration of a fifth embodiment of a wind spinner 72 according to the present invention. Here, the wind spinner 72 is intended to appear like a running dachshund or other small dog. The legs of the dachshund are the blades 34. In this embodiment, there are two sets of blades 34, rather than a single set. As such, it is noted that the present invention is contemplated to encompass any number of separate sets of blades 34 as may be required or desired.
FIG. 10 is an illustration of a sixth embodiment of a wind spinner 74 according to the present invention. Here, the body 18 of the wind spinner 74 is shaped to resemble a sailboat. The blades 34 are shaped to resemble dolphins frolicking around the sailboat.
FIG. 11 is an illustration of a seventh embodiment of a wind spinner 76 according to the present invention. Here, the body 18 is shaped to resemble a martini. The blades 34 are shaped to resemble olives spinning around the martini glass.
FIG. 12 is an illustration of an eighth embodiment of a wind spinner 78 according to the present invention. Here, the body 18 has been reduced to a minimal form. Specifically, the body 18 is formed as a simple connector. While the body 18 rotates, it is contemplated that the body may not rotate, such that rotational motion is defined by the blade pivot 48.
While not shown, the blade reinforcements 58 are located within the blades 34 as in prior embodiments.
In addition, two or more helical embellishments 80 hang from the blades 34. The helical embellishments 80 may be rigid, semi-rigid, or flexible, as required or as desired. In an alternative embodiment, the helical embellishments may be straight ribbons that hang from the blades 34, exhibiting a helical shape only after activation of the wind spinner 78 by the wind 56.
It is noted that the wind spinner 78 shown in FIG. 12 is contemplated to hang from a point above the wind spinner 78. As illustrated, the wind spinner 78 is contemplated to hang from a suspensory device 82, as shown. The wind spinner 78 rotates around the axis 22. The blades 34 are disposed such that the wind 56 causes the spinner 78 to rotate, as discussed in connection with other embodiments.
As should be apparent from FIGS. 6-12, there are innumerable variations of the present invention that may be employed by those skilled in the art without departing from the scope of the present invention.
As noted above, the embodiment(s) described herein are intended to be exemplary of the wide breadth of the present invention. Variations and equivalents of the described embodiment(s) are intended to be encompassed by the present invention, as if described herein.
