DETAILED DESCRIPTION OF THE INVENTION
Example embodiments that incorporate one or more aspects of the present invention are described and illustrated in the drawings. These illustrated examples are not intended to be a limitation on the present invention. For example, one or more aspects of the present invention can be utilized in other embodiments and even other types of devices.
FIG. 1 shows an example embodiment of the present invention in which an air moving apparatus 2 is mounted to an air distribution box 4. In this embodiment, the air moving apparatus 2 is a centrifugal fan that is powered by a motor (not shown) rotating fan blades (not shown) housed within the fan. In a centrifugal fan, an air outlet 6 from which air exits is often rectangular in shape (FIG. 2). However, a different type of air moving apparatus 2, such as an axial fan, may be used and the air outlet 6 may have various shapes, such as a circle (FIG. 6A). In FIG. 1, a mounting plate 8 connects the air moving apparatus 2 to the air distribution box 4 at the air outlet 6 in a manner to be described later.
Although FIG. 1 shows an air moving apparatus 2 and an air distribution box 4, the present invention relates to the connection of a variety of air channeling apparatuses and that present invention is not limited to the connection illustrated in this embodiment. The term “air channeling apparatus” is defined to encompass air directing devices such as distribution boxes, duct tubes, duct rings, plenum attachments or adapters, air moving apparatuses such as centrifugal fans or axial fans, and any other means for transmitting, directing or moving air in a desired manner. Moreover, the present invention has broad applicability in various environments where air is transmitted, directed or moved including, but not limited to, housing applications, commercial applications, recreational vehicles, mobile homes or nautical vehicles.
FIG. 2 shows the air moving apparatus 2 and the mounting plate 8 of the present invention in a detached state. The air moving apparatus 2 has an outward projecting flange 10 around the air outlet 6. The flange 10 generally has a shape similar to that of the air outlet 6 but need not do so. The flange 10 generally has a number of apertures 12 for fastening the air outlet 6 of the air moving apparatus 2 with other air channeling apparatuses via screws. However, such fastening apertures 12 are not used if the present invention is implemented. When the mounting plate 8 is connected with an air channeling apparatus other than an air moving apparatus with a flange, the air channeling apparatus will be equipped with a structure similar to the flange 10 of the air outlet 6.
As shown in FIGS. 3A-3B and 4A-4C, the mounting plate 8 is a substantially flat element with an opening 14 that extends through the mounting plate 8 and allows air to flow through from one air channeling apparatus to another so that they are in air communication with one another. The shape and dimensions of the opening 14 are such that the opening 14 will not act as a hindrance to the air flow. Thus, the opening 14 will ideally be at least as large as the air outlet 6 of the air moving apparatus 2. However, the present invention encompasses situations where the opening 14 is smaller than the air outlet 6. The mounting plate 8 will generally be made of material, such as various types of steel, able to withstand a range of temperatures in which air channeling apparatuses operate.
As shown in FIG. 3B, the mounting plate 8 has a first side 16 and a second side 18. In this embodiment, the first side 16 is substantially flat being free of any projections and the mounting plate 8 is mounted to air channeling apparatuses through welding, gluing, screwing, riveting or other means on the first side 16.
As shown in FIGS. 4A-4C, along certain portions of a periphery 20 of the opening 14 of the mounting plate 8, alignment tabs 22 project from the second side 18 in order to help align the air outlet 6 of the air moving apparatus 2 with the opening 14 of the mounting plate 8. Thus, when assembled, the alignment tabs 22 will project into the air outlet 6 in order to ensure a close fitting with the periphery 24 of the air outlet 6 (FIG. 5A) and to prevent possible slippage between the flange 10 and the second side 18 of the mounting plate 8 after connection. In this embodiment, the alignment tabs 22 will restrict horizontal movement of the mounting plate 8 with respect to the air outlet 6. The alignment tabs 22 may project from different portions of the periphery 20 of the opening 14 and the restriction of movement will vary accordingly. It would also be possible for the alignment tabs 22 to substantially encircle the opening 14 as shown in FIG. 6B.
As shown in FIGS. 3A-3B, 4A-4C and 5B, the mounting plate 8 also includes a first rail 40 that projects on the second side 18 so that it can capture a portion of the flange 10 of the air moving apparatus 2. In this embodiment, an elongate bracket 42 has an upwardly bent projecting surface that acts as the first rail 40 and, when the bracket 42 is fastened to the bottom of the mounting plate 8 with screws, it creates a first capture area 46 in the form of a channel. In this manner, the first capture area 46 can receive a bottom portion of the flange 10. As shown in FIG. 3C, the width of the first capture area 46 of the first rail 40 can be configured to be smaller than the thickness of the flange 10 so that the flange 10 will be tightly gripped by the first rail 40. A lip 48 of the first rail 40 is bent away from the mounting plate 8 to accommodate entry of the flange 10 into the first capture area 46. If the first rail 40 is made of material having a resilient characteristic, it can help accommodate multiple connection and disconnection of air channeling apparatuses. The gripping mechanism can be accomplished in various ways such as by configuring the first rail 40 to be at a slight incline from a parallel position relative to the second side 18 of the mounting plate 8. The first rail 40 can be formed by using brackets 42 of various shapes, such as one forming a capture area 46 through a U-shaped cross section. When the first rail 40 is embodied in a bracket 42 fastened to the mounting plate 8, the bracket 42 will include fastening apertures 50 for screws. The first rail 40 can instead be created by welding, gluing or fastening a separate part, such as the bracket 42, or may be an integral part of the mounting plate 8 created by molding or other material processing methods. In the latter cases, the bracket 42 as shown in this embodiment will not be used.
FIGS. 3A, 4A and 4C also shows a clamp member 68 that has a first end 62 and a second end 64 and that is pivotally connected at the first end 62 to an edge of the mounting plate 8. In this embodiment, as shown in FIGS. 4B and 4C, the clamp member 68 is an elongate bracket 66 with a downwardly projecting surface that acts as a second rail 60 and creates second capture area 70. The second rail 60, similarly to the first rail 40, receives a portion of the flange 10 of the air moving apparatus 2 and can be configured to tightly grip a portion of the flange 10. A pin can be inserted at the first end 62 to pivotally connect the clamp member 60 to the mounting plate. However, various pivoting mechanisms can be used. As shown in FIGS. 4A-4C, the clamp member 68 rests on a portion of the flange 10 of the air moving apparatus 2 and a portion of the mounting plate 8 when the clamp member 68 is pivoted and the second end 64 becomes secured to the mounting plate 8. The second end 64 can be secured through any kind of locking device, such as a locking pin. A locking device that can secure the clamp member 68 without a tool will make installation more convenient. Moreover, the clamp member 68 need not be secured to the mounting plate 8 at the second end 64 and, for example, a middle portion of the clamp member 68 can be fastened to the mounting plate 8 instead.
In this embodiment, the first rail 40 and the second rail 60 will restrict vertical movement after the clamp member 68 is secured to the mounting plate 8. However, depending on the relative shape and position of the first rail 40 and the second rail 60, the manner in which the movement of the flange 10 is restricted by the rails 40, 60 will vary. Alternatively, it is possible for the first and second rails 40, 60 to restrict horizontal movement while the alignment tabs 22 restrict vertical movement. It would also be possible for the first and second rails 40, 60 to restrict movement in a first direction while the alignment tabs 22 restrict movement in a second direction orthogonal to the first direction in which neither the first direction nor the second direction is vertical or horizontal. An example of such an embodiment would be if the alignment tabs 22 and the rails 40, 60 were substantially L-shaped and were located in diagonally opposite corners of the opening 14 and the mounting plate 8 respectively. If the shapes of the flange 10 and the mounting plate 2 were different, the location and geometry of the alignment tabs 22 and the first and second rails 40, 60 will change accordingly. FIG. 6A is such an example.
For this embodiment, the connection of air channeling apparatuses using the mounting plate 8 of the present invention is accomplished by first mounting the first side 16 of the mounting plate 8 onto an air channeling apparatus, such as an air distribution box, to which another air channeling apparatus, such as an air moving apparatus, must connect. Then, a portion of the flange 10 of the air moving apparatus 2 is inserted into the first rail 40 while aligning the air outlet 6 of the air moving apparatus 2 to the alignment tabs 22 of the mounting plate 8 (FIG. 5A). Once the flange 10 of air moving apparatus 2 rests against the second side 18 of the mounting plate 8, the clamp member 68 is rotated to rest against the mounting plate 8 and the flange 10 (FIGS. 1 and 5B). Then, the second end 64 of the clamp member 68 is secured to the mounting plate 8 to hold the flange 10 of the air moving apparatus 2 in place against the mounting plate 8.
In a different embodiment of the invention, it would be possible to have a mounting plate assembly in which the first end 62 of the clamp member 68 is not pre-attached through a pivoting connection to the mounting plate 8 and in which the first and second ends 62, 64 of the clamp member 68 are secured during connection of the air channeling apparatuses.
FIG. 7 shows yet another embodiment of the present invention in which the alignment tabs 22 and the rails 40, 60 exist on or adjacent to the flange 10 of the air moving apparatus 2. The air moving apparatus 2 can be brought into air communication with an air channeling apparatus through the alignment tabs 22 and the rails 40, 60 in the same manner as described above.
The present invention allows the air channeling apparatuses to be connected without the use of tools and without the trouble of having to hold the apparatuses for an extended period of time. Another advantage of the present invention is that it provides an alternative means of connecting air channeling apparatuses where the connection has become impossible due to defects in the apertures.
The invention has been described with reference to the example embodiments described above. Modifications and alterations will occur to others upon a reading and understanding of this specification. Examples embodiments incorporating one or more aspects of the invention are intended to include all such modifications and alterations insofar as they come within the scope of the appended claims.
