The air flow director 100 (hereinafter invention) is a structure that is configured for use with an HVAC system. The invention 100 is configured for use with a grille 161 associated with the HVAC system. The grille 161 is a commercially available HVAC component that is commonly referred to as a grille 161 or a register. The grille 161 is an openwork barrier that is place upon a vent. Specifically, the invention 100 is a device that attaches to the grille 161 for the purpose of changing the direction of the flow of air that is discharged through the grille 161. The invention 100 attaches directly to the grille 161. The invention 100 changes the direction of the air flow through the grille 161 in a traverse direction and a lateral direction.

The invention 100 comprises a lateral rotation 121 around a lateral axis of rotation 122 and a traverse rotation 123 around a traverse axis of rotation 124. The lateral rotation 121 does not require the invention 100 to be disconnected from the grille 161. The traverse rotation 123 does not require the invention 100 to be disconnected from the grille 161. The rotation of the invention 100 around the lateral axis of rotation 122 adjusts a lateral deflection angle 153 of the air flow. The rotation of the invention 100 around the traverse axis of rotation 124 adjusts a traverse deflection angle 150 of the air flow. The invention 100 comprises a first triangular panel 101, a second triangular panel 102, a deflection panel 103, and a fastener 104. The first triangular panel 101 and the second triangular panel 102, are attached to the deflection panel 103. The fastener 104 attaches the deflection panel 103 to the grille 161.

Within this disclosure, a wall 163 refers to a vertical surface within which the grille 161 has been installed. It is explicitly acknowledged that a grille 161 can be used with a floor-mounted vent. However, the specification and claims of this disclosure will hereinafter implicitly assume that the grille 161 is mounted in a vertical wall 163. This assumption is made for the purposes of simplicity and for clarity of exposition of the disclosure is not intended to limit the scope of the appended claims. Those skilled in the art will recognize that the innovations described in this disclosure can be readily modified to accommodate a grille 161 mounted in a horizontal surface, such as a floor or a ceiling with a minimum of modification and experimentation.

Within this disclosure, a bar 164 refers to shaft structures that are used to form the openwork of the grille 161.

Within this disclosure, an air flow vector 162 is a hypothetical vector that describes the movement of air flow out of the invention 100. Specifically the air flow vector 162 describes the direction of movement of the center mass of the airflow discharged from the invention 100. The air flow vector 162 is further defined with the traverse deflection angle 150 and the lateral deflection angle 153. The traverse deflection angle 150 is defined as the cant between the surface of the wall 163 and the air flow vector 162. The lateral deflection angle 153 is defined as the cant between the geometric projection of the air flow vector 162 on the wall 163 and a hypothetical reference line 155, generally taken to be a vertical line, formed within the plane of the wall 163 that passes through the center of the grille 161. The air flow vector 162, the traverse deflection angle 150 and the lateral deflection angle 153 are used as a directional reference throughout this disclosure. The invention 100 provides for the adjustment of the traverse deflection angle 150 and the lateral deflection angle 153 such that the air flow vector 162 of the airflow discharged from the invention 100 can be controlled.

The first triangular panel 101 is a solid plate structure that is formed in the shape of a scalene triangle. The second triangular panel 102 is a solid plate structure that is formed in the shape of a scalene triangle. The first triangular panel 101 and the second triangular panel 102 have identical form factors. The first triangular panel 101 is further defined with a first edge 131, a second edge 132, and a third edge 133. The second triangular panel 102 is further defined with a fourth edge 134, a fifth edge 135, and a sixth edge 136. The first triangular panel 101 is identical to the second triangular panel 102.

The first triangular panel 101 and the second triangular panel 102 are both further defined with a primary traverse deflection angle 151, a secondary traverse deflection angle 152, and a pivot angle 154.

The primary traverse deflection angle 151 of the first triangular panel 101 is the angle formed by the intersection of the second edge 132 and the third edge 133 of the first triangular panel 101. The primary transverse deflection angle 151 of the second triangular panel 102 is the angle formed by the intersection of the fifth edge 135 and the sixth edge 136 of the second triangular panel 102.

The secondary traverse deflection angle 152 of the first triangular panel 101 is the angle formed by the intersection of the first edge 131 and the third edge 133 of the first triangular panel 101. The secondary traverse deflection angle 152 of the second triangular panel 102 is the angle formed by the intersection of the fourth edge 134 and the sixth edge 136 of the second triangular panel 102.

The pivot angle 154 of the first triangular panel 101 is the angle formed by the intersection of the first edge 131 and the second edge 132 of the first triangular panel 101. The pivot angle 154 of the second triangular panel 102 is the angle formed by the intersection of the fourth edge 134 and the fifth edge 135 of the second triangular panel 102.

The deflection panel 103 is a solid plate structure that is formed in the shape of a rectangular block. The deflection panel 103 is further defined with a seventh edge 137, an eighth edge 138, a ninth edge 139, and a tenth edge 140.

The fastener 104 is a device that attaches the invention 100 to the grille 161. The fastener 104 comprises a spring 110, a hook 113, and a flange 114. The spring 110 is further defined with a first end 111 and a second end 112.

The spring 110 is a readily and commercially available tension spring that is formed in the shape of a tube. The span of the spring 115 is selected such that the spring 110 is under tension when the invention 100 is attached to the grille 161. The span of the spring 115 refers to the distance between the first end 111 of the spring 110 and the second end 112 of the spring 110. A measurement of the span of the spring 115 is taken when: 1) the spring 110 is in its relaxed shape; and, 2) the center axis of the spring 110 forms a straight line. In the first potential embodiment of the disclosure, the spring 110 is a bungee cord.

The hook 113 is a readily and commercially hardware item that attaches the first end 111 of the spring 110 to the grille 161. The flange 114 is a readily and commercially hardware item that attaches the second end 112 of the spring 110 to the deflection panel 103.

The third edge 133 of the first triangular panel 101 attaches to the tenth edge 140 of the deflection panel 103. The sixth edge 136 of the second triangular panel 102 attaches to the eighth edge 138 of the deflection panel 103. The flange 114 attaches the second end 112 of the spring 110 to the deflection panel 103. The hook 113 attaches to the first end 111 of the spring 110.

The first triangular panel 101 attaches to the deflection panel 103 such that the first triangular panel 101 forms a right angle with the deflection panel 103. The second triangular panel 102 attaches to the deflection panel 103 such that the second triangular panel 102 forms a right angle with the deflection panel 103. The second triangular panel 102 is parallel to the first triangular panel 101 and projects away from the deflection panel 103 in the same direction as the first triangular panel 101.

The invention 100 attaches to the grille 161 using an arrangement selected from the group consisting of a first arrangement and a second arrangement.

In the first arrangement, the second edge 132, the fifth edge 135, and the ninth edge 139 are placed flush against the wall 163. The invention 100 attaches to the grille 161 using the hook 113 attached to the first end 111 of the spring 110. When the hook 113 is hooked around a bar 164 of the grille 161, the spring 110 is placed under tension. The counter force that prevents the spring 110 from returning to its relaxed state is transmitted through the invention 100 to the second edge 132, the fifth edge 135, and the ninth edge 139 such that the second edge 132, the fifth edge 135, and the ninth edge 139 are held flush against the wall 163. The air flowing through the grille 161 deflects against the deflection panel 103 before exiting the invention 100 in the direction of the air flow vector 162. Using the first arrangement, the traverse deflection angle 150 formed by this deflection is equal to the primary traverse deflection angle 151 of both the first triangular panel 101 and the second triangular panel 102.

In the second arrangement, the first edge 131, the fourth edge 134, and the seventh edge 137 are placed flush against the wall 163. The invention 100 attaches to the grille 161 using the hook 113 attached to the first end 111 of the spring 110. When the hook 113 is hooked around a bar 164 of the grille 161, the spring 110 is placed under tension. The counter force that prevents the spring 110 from returning to its relaxed state is transmitted through the invention 100 to the first edge 131, the fourth edge 134, and the seventh edge 137 such that the first edge 131, the fourth edge 134, and the seventh edge 137 are held flush against the wall 163. The air flowing through the grille 161 deflects against the deflection panel 103 before exiting the invention 100 in the direction of the air flow vector 162. Using the second arrangement, the traverse deflection angle 150 formed by this deflection is equal to the secondary traverse deflection angle 152 of both the first triangular panel 101 and the second triangular panel 102.

In both the first arrangement and the second arrangement, the apex of the pivot angle 154 of the first triangular panel 101 and the apex of the pivot angle 154 of the second triangular panel 102 will be in contact with the wall 163.

The traverse deflection angle 150 is adjusted by changing between the first arrangement and the second arrangement of attaching the invention 100 to the grille 161. The change between the first arrangement and the second arrangement does not require that the hook 113 be unattached from the grille 161.

To switch between the first arrangement and the second arrangement requires a traverse rotation 123 of the invention 100 around the traverse axis of rotation 124. The traverse rotation 123 refers to a rotation of the invention 100 within a plane of rotation that is: 1) perpendicular to the plane of rotation of the lateral rotation 121; and, 2) that contains the hypothetical reference line 155 that is used to determine the lateral deflection angle 153. The traverse axis of rotation 124 refers to the axis of rotation around which a traverse rotation 123 of the invention 100 is made. The traverse axis of rotation 124 is a line that is formed between the apex of the pivot angle 154 of the first triangular panel 101 and the apex of the pivot angle 154 of the second triangular panel 102. Once the rotation is complete, the invention 100 is placed in its final position by sliding the invention 100 along the wall 163.

The lateral deflection angle 153 is adjusted through a lateral rotation 121 of the invention 100 around the lateral axis of rotation 122 after the invention 100 has been attached to the grille 161 and slid into position. The term lateral rotation 121 refers to a rotation of the invention 100 within a plane of rotation that is parallel to or aligned with the plane formed by the wall 163. The lateral axis of rotation 122 refers to the axis of rotation around which a lateral rotation 121 of the invention 100 is made. The lateral axis of rotation 122 is a line that projects perpendicularly away from the wall 163. The lateral axis of rotation 122 is aligned with the center axis of the spring 110. It is expected that the lateral rotation 121 of the invention 100 around the lateral axis of rotation 122 will cause a torque within the spring 110. However, the lateral rotation 121 of the invention 100 does not require that the hook 113 be unattached from the grille 161.
