DETAILED DESCRIPTION
Example mounted light and fan units disclosed herein for use vehicle loading docks include both a light and a fan. While cargo is being transferred to or from the cargo bay of a vehicle parked at the dock, the light illuminates the cargo bay while the fan ventilates it. In some examples, a fan axis of the fan's impeller can be changed selectively to horizontal and vertical orientations. Some examples of the mounted light and fan include an articulated arm mounted to a building wall by way of a bracket that is vertically adjustable. In some examples, a curved frame couples the articulated arm to the fan's housing, wherein the frame serves as a conduit for electrical wiring extending between the light and a controller. Some examples of the mounted light and fan include dual-grip handlebars for aiming the fan and the light.
FIGS. 1-3 show an example mounted light and fan apparatus 10 secured to a building structure 12 (e.g., a wall, a doorframe, a bollard, a post, etc.) at a vehicle loading dock 14. The example apparatus 10 includes a fan 16 for ventilating an interior cargo bay 20 of a vehicle 22 (e.g., a truck, a trailer, etc.) parked at dock 14. Further, the example apparatus 10 includes a light 18 for illuminating the interior cargo bay 20 of the vehicle 22.
In the illustrated example, the dock 14 includes a building 24, a wall 26 with a doorway 28, a driveway or approach 30 leading to the doorway 28, a door 32, an elevated floor 34 of the building 24, a dock leveler 36 having an adjustable deck 38 and an extendible lip 40, and a vehicle restraint 42. Opening the door 32 of the dock 14 and a rear door 44 of the vehicle 22 enables cargo to be transferred between the building 24 and the vehicle's cargo bay 20. To aid loading and unloading operations, the dock leveler 36 provides a bridge between the dock floor 34 and the vehicle 22 across which the cargo can be transferred between the vehicle 22 and the building 24 while the vehicle restraint 42 helps secure the vehicle 22 at the dock 14. During the loading and/or unloading process(es), the mounted light and fan apparatus 10 helps illuminate and ventilate the vehicle's cargo bay 20 while reducing (e.g., minimizing) obstruction to movement through the doorway 28.
Details and alternatives of the mounted light and fan apparatus 10 are shown in FIGS. 4-20. Some examples of the apparatus 10 comprise a mounting bracket 46, a fan and light unit 48 (FIG. 11), and an articulated arm 50. The mounting bracket 46 is secured to a building structure 12. The fan and light unit 48 comprises a fan 16, a light 18, and a frame 52 coupled to both the fan 16 and the light 18. The fan and light unit 48 is also referred to herein as an illuminating fan assembly. The articulated arm 50 connects the fan and light unit 48 to the mounting bracket 46 to provide an adjustable support means for selectively positioning and aiming the fan and light unit 48. In some examples, the fan 16 and the light 18 are attached to the frame 52 to point in substantially the same direction (e.g., within 5 degrees of one another). In other examples, the light 18 may point in a direction that is offset relative to the direction in which the fan 16 is pointing. In some examples, the relatively direction of the fan 16 and the light 18 may be user-adjustable. In other examples, both the fan 16 and the light 18 are rigidly affixed to the frame so that the relative direction of the fan 16 and the light 18 is fixed. That is, in some examples, the fan 16 and the light 18 may be held in fixed relationship relative to one another.
Referring to FIG. 11, some examples of the fan and light unit 48 comprise the fan 16, the light 18, the frame 52, and one or more controllers 54 for the light 18 and/or the fan 16, a first handle 56 and a second handle 58. In some examples, the first handle 56 comprises a portion of or extends from the frame 52. In some examples, the second handle 58 comprises a portion of or extends from the housing of the fan 16. FIG. 16 shows an example user interface 60 of the controller 54. In this example, the user interface 60 is specific to operation of the light 18. Separate controls for operation of the fan 16 (e.g., FIG. 7, 9, 17, 19) may be provided via another user interface of the controller 54. In other examples, controls for the fan 16 may be provided via a user interface of a separate controller specific to the fan. Alternatively, the controller 54 may be used to operate either or both of the light 18 and the fan 16 to selectively power each component (e.g., the fan 16 and/or the light 18) on or off, increase/decrease power/intensity, enable automatic (sensor-controlled) output modulation, and/or set/start/stop a timer for changing a power state for one or both of the components. In some examples, the automatic output modulation enables the fan 16 and/or the light 18 to be controlled by one or more sensors (e.g., motion, ambient light, temperature, etc.). In some examples, the one or more sensors may be incorporated and/or integrated with the fan 16, the light 18, and/or the controller 54. Additionally or alternatively, the one or more sensors may be separate from but carried by the fan 16, the light 18, the controller 54, and/or the frame 52. Further, in some examples, one or more of the sensors may be spaced apart from the fan and light unit 48 but in communication with the fan 16, the light 18, and/or the controller 54. In some examples, the controller 54 powers off the fan 16 and/or the light 18 after a certain time period in which motion in the area proximate the unit 48 was not detected by a motion sensor. In other examples, the controller 54 powers on the fan 16 and/or the light 18 when motion in the area proximate the unit 48 is detected by a motion sensor. In some examples, the motion sensor is positioned to monitor the area toward which the fan 16 and the light 18 are pointed. Additionally or alternatively, the motion sensor is positioned to monitor an area other than in the direction that the fan 16 and the light 18 are pointing. Signals from various types of sensors could be used alone or in combination to control the fan 16 and/or the light 18 in different use cases and environmental scenarios.
In some examples, the frame 52 comprises a hollow bar or tubular conduit 62 with an internal channel through which an electrical wire 64 (represented by the dashed line in FIG. 11) runs between the controller 54 and the light 18. In some examples, the bar or conduit 62 is rigid to provide structural support for the other components of the fan and light unit 48. In the illustrated example, the conduit 62 has a generally square cross-section. However, other cross-sectional shapes (e.g., circular, rectangular, etc.) may alternatively be used. The electrical wire 64 is just one example of a controlling communication link 66 operatively connecting the controller 54 to the light 18 and/or the fan 16. In some examples, the tubular conduit 62 curves and/or bends about a fan axis 68 and, more generally, about a housing 72 of the fan to reduce (e.g., minimize) structural weight, enhance the unit's appearance, and/or to make it easier to feed the wire 64 through the conduit 62 during assembly. More particularly, in some examples, the frame 52 extends between the controller 54 and the light 18 with a bend such that the controller 54 is positioned proximate a backside of the fan 16 with the light 18 being positioned proximate (but spaced apart from) a top and/or side of the fan 16. In some examples, all three of the fan 16, the light 18, and the controller 54 are aligned within a common plane defined by the curve or bend in the conduit 62. Further, in some examples, the relative position of the fan 16, the light 18 and the controller 54 (due to the shape of the frame 52) generally corresponds to a right triangle with the fan 16 at the right angle of the triangle. In some examples, to enable this arrangement, the tubular conduit 62 curves approximately (e.g., within 5 degrees of) 90 degrees. In other examples, the frame 52 may be formed of straight pieces of conduit 62 connected at joints defining suitable angles (e.g., two pieces connected by a 90 degree joint, three pieces connected in series by two 135 degree joints, etc.). In some examples, additional wiring 70 for the fan 16 and/or the light 18 is strung external of the frame 52 and the articulated arm 50, as shown in FIG. 5. In some such examples, the controller 54 may be spaced apart from the fan and light unit 48.
In the illustrated examples, the fan 16 comprises a fan housing 72 containing a centrifugal impeller 74 (FIG. 1). The fan housing 72 defines a suction air inlet 76 and an air discharge outlet 78. An electric motor inside housing 72 rotates the impeller 74 about a fan axis 68 to force air 80 from the inlet 76, into the housing 72, out through the outlet 78 toward the direction the fan 16 is pointing (e.g., into the vehicle's cargo bay 20). The articulated arm 50 allows the fan 16 and the light 18 to be positioned and repositioned with respect to the structure to which it is mounted.
In some examples, the articulated arm 50 comprises a proximal arm 82 pivotally coupled to a distal arm 84. The proximal arm 82 is coupled to the mounting bracket 46, and the distal arm 84 is coupled to the fan and light unit 48 via the frame 52. The articulation of arm 50 is accomplished by way of several pivotal connections. In some examples such as that shown in FIG. 6, multiple ones of the pivotal axes of these connections are generally parallel (e.g., parallel to within 5 degrees) to one another. For example, a first pivotal connection 86, defining a first axis 88 (generally vertical in the illustrated example), couples the proximal arm 82 to the mounting bracket 46 such that proximal arm 82 is pivotal about the first axis 88 relative to the mounting bracket 46. A second pivotal connection 90, defining a second axis 92 (generally vertical in the illustrated example), couples the distal arm 84 to the proximal arm 82 such that the distal arm 84 is pivotal relative to the proximal arm 82 about the second axis 92. A third pivotal connection 94, defining a third axis 96 (generally vertical in the illustrated example), couples a positioning bracket 97 to the distal arm 84 such that positioning bracket 97 is pivotal relative to the distal arm 84 about the third axis 96. As shown in the illustrated example, the proximal arm 82 and the distal arm 84 include elongate beams that connected at their ends. Therefore, the proximal arm 82 and the distal arm 84 extend in elongate directions that are substantially perpendicular to the first, second, and third axes 88, 92, 96. A fourth pivotal connection 98 defining a fourth axis 100 (generally horizontal in the illustrated example) couples the fan and light unit 48 via the frame 52 to the positioning bracket 97 along the third axis 96 below the third pivotal connection 94. Thus, in the illustrated example, the fourth axis 100 is substantially (e.g., within 5 degrees) perpendicular to the first, second, and third axes 88, 92, 96. As a result, the fan and light unit 48 (including the frame 52) is independently positional pivotally about the third axis 96 and the fourth axis 100, the third and fourth axes 96, 100 intersecting. In some examples, the tightness of the bolts and/or other hardware at the respective pivotal connections 86, 90, 94, 98 controls the freedom with which the components of the articulated arm 50 rotate relative to one another. That is, when the bolts and/or other hardware is relatively loose, the components may easily rotate relative to one another. By contrast, when the bolts are tightened, rotation at the pivotal connections may be significantly reduced and substantially prevented (at least by manual force).
Although the actual construction details of the articulated arm 50 may vary, some examples of the proximal arm 82 comprises an upper beam 102 and a lower beam 104, wherein the distal arm 84 is interposed between the upper and lower beams 102, 104 at the second pivotal connection 90, and both the upper and lower beams 102, 104 are coupled to the mounting bracket 46 via the first pivotal connection 86. In some examples, one or more spacers 105 are positioned at intermediate position(s) along the proximal arm 82 between the upper and lower beams 102 to provide support the proximal arm 82. To provide the distal arm 84 with additional support, some examples of the articulated arm 50 include a diagonal tensile brace 106 having one end 108 connected to the proximal arm 82 and an opposite end 108 connected to the distal arm 84. The illustrated example shows the diagonal tensile brace 106 having a central portion 110 that lies at an incline, i.e., the central portion 110 is displaced out of parallel alignment with both the proximal arm 82 and the distal arm 84.
In some examples, the distal arm 84 comprises a base segment 112 and an extension segment 114. In some examples, the base segment 112 is coupled to the proximal arm 82 via the second pivotal connection 90, the extension segment 114 is coupled to the frame 52 via the third pivotal connection 94 and the fourth pivotal connection 98, and the extension segment 114 is telescopically coupled to the base segment 112. The telescopic connection makes it possible to readily adjust the length of the distal arm 84. In some examples, the particular length at which the extension 114 extends out from the base segment 112 is fixed via a bolt 115 extending through both the base segment 112 and the extension 114 at the distal end 108 of the tensile brace 106. In some examples, the extension 114 includes a series of spaced apart holes distributed along its length through which the bolt 115 may extend to maintain the extension 114 at a fixed telescopic position relative to the base segment 112.
To reduce (e.g., minimize) obstruction by the unit 48 of traffic between the vehicle cargo bay 20, through the doorway 28, and into the building 24 (i.e., the traffic way), and/or to reduce (e.g., minimize) obstruction by traffic (i.e., forklifts, loads, dock workers) of the air stream(s) and light beam(s) produced by the unit 48, the fan and light unit 48 may be positioned near the upper corner of the doorway 28. With the articulated arm 50 (including positioning bracket 97) providing various degrees of adjustable freedom and length, a dockworker may use the first handle 56 to easily position the fan and light unit 48 relative to the building structure 12, the doorway 28, the vehicle 22, and/or traffic way associated with the dock between various use positions and various stored positions. In some examples, the first handle 56 may also be used to aim the fan 16, and associated air stream(s), and the light 18, and associated light beam(s), relative to the building structure 12, the doorway 28, the vehicle 22, and/or traffic way associated with the dock. To increase (e.g., maximize) the elevation of the fan 16 and the light 18 with respect to the dock floor 34 while keeping the unit 48 within a dockworker's reach, the first handle 56 may be positioned or located at or near the lower edge of the unit 48 (i.e., lower than the fan axis 68 (e.g., a midpoint of the fan 16), the controller 54, and/or the light 18). In some examples, the elevation of the controller 54 is positioned below that of the light 18 to increase (e.g., maximize) the elevation of the light 18 in order to reduce (e.g., minimize) obstruction of the light shining into the cargo bay 20 while keeping the controller 54 within reach of the dockworker. The first handle 56 may be of a shape that enables ergonomic positioning of the unit 48. In the illustrated example, the first handle 56 is in the form of a handlebar with two handgrips 116 (generally perpendicular to the third axis 96 and generally parallel to the fourth axis 100) to make it easier for the dockworker to position and aim the fan 16 and the light 18. In some examples, the first handle 56 is an integral feature of the frame 52. Some examples of the fan and light unit 48 include the second handle 58 with a handgrip generally perpendicular to those of the first handle 56, which provides a dockworker with more options for gripping to position and aim the fan and light unit 48. In some examples, the second handle 58 is an integral feature of the fan housing 72. In operation, a dockworker can grasp some combination of the handgrips 116 and the second handle 58 simultaneously (e.g., one hand on the first handle 56 and the other hand on second handle 58) to position the fan and apply a rotational moment about the axis 96 to aim the fan 16 and the light 18 horizontally (e.g., when the third axis 96 is oriented vertically) and about the axis 100 to aim the fan 16 and the light 18 vertically (e.g., when the fourth axis 100 is oriented horizontally).
Referring to FIGS. 12-15, some examples of the apparatus 10 have an adjustable mounting bracket 46′ comprising a track 118 and a track follower 120 that render the articulated arm 50 and the fan and light unit 48 movable along the track 118 relative to the structure 12 to which the bracket 46′ is mounted. In some examples, the track extends in a direction that is substantially parallel (e.g., within 5 degrees) to the first axis 88 and, therefore, substantially perpendicular (e.g., within 5 degrees) to the direction in which the proximal arm 82 extends from the bracket 46′. As a result, when the adjustable mounting bracket 46′ is mounted to the structure 12 with the track 118 extending vertically, the articulated arm 50 extends horizontally with the fan and light unit 48 being enabled to be selectively raised (vertically) for additional clearance underneath the unit 48 or lowered to an elevation more suitable for positioning and/or ventilating and/or illuminating the vehicle's cargo bay 20 and then being maintained in that vertical position until being subsequently and selectively raised or lowered. In some examples, the wall mounting bracket 46′ is adjustable by way of an actuator 122 such as, for example, a crank-up screw jack 124 manually powered by a crank 126, a motorized linear actuator, a powered cylinder, a spring and/or various combinations thereof, etc.
Some examples of the apparatus 10 include a fan and light unit 48 with a different orientation of the fan 16 with respect to the light 18 and/or the frame 52. For example, the fan 16 can be set at a horizontal orientation with the fan axis 68 being substantially horizontal with the discharge outlet 78 positioned so as to be at the top of fan 16, as shown in FIGS. 6-10, or a vertical orientation with the fan axis 68 being substantially vertical with the discharge outlet 78 positioned so as to be to the side of fan 16, as shown in FIGS. 17-20. To achieve this, some examples of the apparatus 10 have a frame plate 130 (FIG. 11) on the frame 52 and a mating mounting surface 128 on the fan housing 72. In some examples, the controller 54 is positioned adjacent and/or attached to the frame plate 130 on an opposite side to the fan 16. Bolt hole patterns 131 in the frame plate 130 and corresponding holes in the mounting surface 128 are symmetrical such that the frame plate 130 can be attached to the mounting surface 128 selectively in a first orientation (e.g., FIGS. 6-10) and a second orientation (FIGS. 17-20). In some examples, the pattern of holes 131 is positioned so as to surround the controller 54 that is also attached to the frame plate 130. As most easily seen in FIG. 17, the alternate mounting arrangements for the unit 48 enables the unit 48 to be positioned relative to the building structure 12, the doorway 28, the vehicle 22, and/or traffic way associated with the dock such that a reduced (e.g., minimal) portion of the apparatus 10 (particularly, the outlet 78 of the fan 16) extends into or near the traffic way while still ventilating and illuminating the cargo bay 20. That is, as shown in the illustrated examples, the outlet 78 of the fan 16 extends across substantially the full width of the fan 16 when oriented upright (e.g., as shown most clearly in FIG. 9) such that the entire fan housing 72 would need to be within the doorway 28 and/or traffic way to enable the entire outlet 78 to be exposed to the cargo bay 20 of the vehicle 22. By contrast, when the fan 16 is oriented on its side with the outlet 78 oriented vertically to one side (e.g., as shown in FIG. 17) a considerable portion of the fan housing 72 may be positioned outside of the doorway 28 and/or the traffic way if the light 18 is positioned directly adjacent the edge of the doorway 28 (e.g., just inside the door jamb) while still enabling the entire outlet 78 to be exposed to the cargo bay 20 of the vehicle 22.
In the examples shown in FIGS. 19 and 20, a vertical single handgrip handle 55 extends down from the frame 52 (perpendicular to the second handle 58 of the 90 degree rotated fan) replacing the horizontal handlebar-style handle 56. In operation, a dockworker can grasp the handles 55, 58 simultaneously (e.g., one hand on the single handgrip handle 55 and the other hand on the second handle 58) to position the fan 16 and apply a rotational moment about the axis 96 to aim the fan 16 and the light 18 horizontally (e.g., when the third axis 96 is oriented vertically) and about the axis 100 to aim the fan 16 and the light 18 vertically (e.g., when the fourth axis 100 is oriented horizontally).
In addition to being able to mount the fan 16 horizontally or vertically, it should be noted that in some examples, such as the examples shown in FIGS. 19 and 20, the fan 16 can be flipped over 180 degrees about a horizontal axis. FIG. 20, for instance, shows the fan 16 being mounted 180-degrees from its orientation shown in FIG. 19. Being able to mount the fan 16 in either position can be advantageous depending on whether the mounting bracket 46 or 46′ is mounted on the right or left side of the doorway 28.
As mentioned above, the hollow bar or tubular conduit 62 of the frame 52 may have different cross-sectional shapes and/or have different types of bends along its length between the controller 54 and the light 18. Several different examples are shown in FIGS. 21-26. In particular, FIG. 21 illustrates the frame 52 with the example conduit 62 having a square cross-section and a curved bend. FIG. 22 illustrates the frame 52 with the example conduit 62 having a round cross-section and a curved bend. FIG. 23 illustrates the frame 52 with the example conduit 62 having a square cross-section and an approximately 90 degree bend. FIG. 24 illustrates the frame 52 with the example conduit 62 having a round cross-section and an approximately 90 degree bend. FIG. 25 illustrates the frame 52 with the example conduit 62 having a square cross-section and two approximately 135 degree bends. FIG. 26 illustrates the frame 52 with the example conduit 62 having a round cross-section and two approximately 135 degree bends.
