Claims. (Cl. 219-39) This invention relates to fan or ventilator units which are adapted for flush mounting in room ceilings. The invention is directed to novel means for demountably suspending a fan and motor assembly from an outer housing which is permanently installed in a recess in the ceiling of a room.

A typical ceiling fan consists essentially of an outer box-like housing, an electric motor and fan disposed within the housing, and a grill or ventilator cover disposed over the face of the fan and housing. A typical unit in which such elements are utilized in conjunction with an air heater and an electric light is shown in Joseph R. Corbett 'co-pending patent application, Serial No. 210,422, filed February 10, 1-951, for Ceiling Heater and Ventilator.

Whether or not the fan unit happens to have associated with it,.a heater, an electric light, or both, as shown in the aforesaid patent application, conventional practice in the installation of the equipment involves, first, the insertion of the housing into an appropriate aperture or space above the ceiling level, between the building joists. To facilitate such installation, it is highly desirable :if :not requisite that the fan motor and associated elements be removable as a unitary assembly from the housing. This .is especially desirable in new building construction where installation of the housing precedes the plastering and finishing of the ceiling, which operations might result in damage to the working elements. Thus, the fan unit is ordinarily made separable from the housing, and the electrical connection to the fan is completed after the housing has been permanently mounted within its recess.

For the sake of safety and appearance, the electrical connection to the fan is completed within the confines of the housing so that the wiring is fully protected and is ultimately excluded from view. this electrical connection, it has heretofore been necessary that the electrician or his helper manually lift and hold the fan and motor assembly in an elevated position adjacent and below the housing while the wires are being attached, or :to :rig a temporary rope sling or scalfold for-supporting the fan assembly. After the electrical-connections arecornpleted thefanand motor assembly is lifted bodily into place within the housing where it is fastened by meansof appropriate bolts.

Supporting the fan assembly at \ceiling height adjacent but outside the housing is obviously a tiring and cum- 'brous task. Moreover, it is necessary :not only when the unit is originally installed but also whenever the fan is to be cleaned or repaired. It is frequently desirable for the householder to have access to the fan blades and the housing interior in order that-accumulations .of dust, grease or grime may be removed. In :that :event, the fan assembly may be loosened from the housing, but it is necessary for someone to hold it .in an elevated position. It the fan assembly is allowed to be suspended by the electric wires, damage to them is almost certain to occur because of the weight of the assembly.

The principal objective of the present invention has been to provide a novel support for a fan assembly which permits it .to .besuspended in an out of the way position either while the electrician performs the connection of the wires of the fan unit to the household circuit, or while the fan assembly and housing interior are being cleaned or repaired.

A further objective .of .the .inventionhas :been to provide a hinge :support from which the fan assembly may :In order to complete the housing.

be suspended but which, in turn, is capable of exerting a binding force upon its parts during normal usage of the fan so as to prevent any rattling of the parts when the fan is operating.

Briefly, the structure of the invention which provides these functions includes a bracket secured to the housing, and a hanger joined to the fan assembly which engage one another to form a hinge by means of which the fan assembly may be supported or suspended from In the preferred embodiment the bracket includes a portion projecting outwardly from the housing wall and having an aperture formed therein. The hanger is provided with an angulated tang receivable githin this aperture to form a pivoted connection, or

mge.

To suspend the fan from the housing the electrician lifts the assembly until the tang is disposed above the bracket and then lowers it until the tang slips into place in the bracket aperture. The assembly can thus be suspended by means of the hinge until the wiring is completed, after which the assembly is rotated upwardly about the hinge into a nested position within the housing. The fan assembly is supported in the nested position by the hinge and one or more mounting feet secured to the assembly and bolted to cooperating members of the housing.

The hinge thus provides a simple means for orienting the assembly with the housing so that each of the feet on the assembly will be properly aligned with its corresponding element of the housing, and the lead-in wires for the fan motor will be disposed opposite the outlet box. In the preferred embodiment, the bracket is secured to the housing near the junction box and the hanger is mounted adjacent to the lead-in wires of the fan assembly so that when the hanger and bracket are brought into engagement the lead-in wires are automatically positioned beneath the outlet box, ready for connection to the house wires. After the connections are completed, any excess wire can be pushed into the junction box and consequently only a minimum length of wire is used to connect the fan motor, heating coil, and light bulb, if any; and the air passageways within the housing are left free from obstruction.

In addition to the construction just described the hinge is arranged to prevent, in a simple way, vibration or chattering of the ,fan assembly after it has been installed in the housing and the fan is in operation. For this purpose, the bracket is provided with an angulated binding segment and the hanger tang is configurated to form a cooperating foot so that when the fan assembly is swung upwardly about the hinge into the nested position there is a binding action between the binding segment and the tang foot providing a firm mounting for the assembly even if some of the bolts fastening the mounting feet to the housing should become loosened.

These and other objects and advantages of the present invention will be apparent from a further consideration of the following detailed description of the drawings in which a typical embodiment of the invention is disclosed.

In the drawings:

Figure 1 is a side elevational view, partly in section and partially broken away, of the fan assembly and housing showing the manner in which the fan assembly resides within the housing.

Figure 2 is a bottom elevational view of the fan assembly and housing.

Figure 3 is an enlarged bottom elevational view of the fan assembly mounting hinge.

Figure 4 is a cross sectional view taken along line 44 of Figure 3.

Figure 5 is a view similar to Figure 4 showing the hinge with the fan assembly in the dropped position.

Figure 6 is a side elevational view of the housing with the fan assembly in a dropped position, the housing being partially broken away to show the electrical connection of the fan assembly lead-in wires to the house wiring system.

Figure 7 is a side elevational viewof the fan installed in the ceiling.

As shown in Figures 1 and 2, one type of ceiling fan with which the mounting means of the present invention may be used comprises an outer housing 10, which is adapted to fit into a recess in the ceiling of a bathroom, dressing room, or the like, and a fan assembly 11, mounted within the housing by means of hinge 13 and cooperating feet 14 and 15. Fan assembly 11, includes fan motor 16, a plurality of arms 50 and fan blades 51 rotated by the motor, a divider shell 17 and, in one preferred embodiment, a light 18, and an electric resistance heating coil 52. A grill 19 is carried by shell 17 and provides an attractive cover for the air discharge opening 20.

In the installed or nested position, the fan assembly 11 resides .within the outer housing and is supported by means of hinge 13 and one or a plurality of feet 14 and cooperating elements 15 which are respectively riveted or otherwise secured to shell 17 and the outer housing 10. The fan assembly also includes lead-in wires 21 for the fan motor, heating resistance and electric lamp. These wires are joined as at 22 to wires 23 of the house wiring circuit which are brought into the housing through openings 24 in junction box 25 which is mounted on the outer housing wall. Cover plate 26 is secured to the inner surface of the housing wall as by bolts 27 to complete l the enclosure of box 25.

As shown in Figures 3, 4 and 5, the hinge 13 com-' prises a bracket 28 which is riveted or otherwise secured to the outer housing 10, and a hanger 30, similarly secured to the fan assembly 11. Bracket 28 is preferably constituted by a strip of metal configurated to form a base segment 31 which resides against the housing, a projecting segment 32 which extends outwardly from the housing wall, and an angulated segment 33 which depends from the end of projecting segment 32. An aperture 34 is provided in projecting segment 32 for receiving tang 35 formed on hanger 30.

Hanger preferably includes an attaching web 36 which is riveted or otherwise secured to a member of the fan assembly such as shell 17, and an extending web 37 which engages bracket 28. A tang 35, struck from the extending web 37 is adapted for insertion in aperture 34 formed in bracket 28. Tang is generally L shaped, but the foot 38 of the L constitutes a binding surface for engagement with edge 39 of bracket 28 when the fan assembly is rotated into the nested position. Thus, the relative angulation of the foot 38 of the tang 35 and the depending segment 33 of the bracket are such that when the fan assembly 11 is swung upwardly into the nested position shown in Figure 1, edge 39 bears against foot 38 urging the assembly counter-clockwise downwardly into the dropped position. When the fan assembly is in the nested position the feet 14 secured to shell are disposed above the cooperating feet 15 of the housing 10, consequently, even if the bolts securing these feet together should become loosened, the fan assembly will not vibrate or chatter when the fan is in operation since the two sets of feet reside in pressure engagement with one another. On the other hand, the fan assembly readily may be demounted from the housing by removal of the tank 35 from aperture 34 thus separating the hinge elements from one another.

To install a heater in the ceiling, the outer housing 10 is secured to suitable structural members such as cross headers 40, by means of screws 41 which pass through suitable apertures provided in mounting lugs 42. Next wires 23 of the house wiring circuit are brought into the junction box 25 through aperture 24, as shown in Figure 6. The fan asssembly is then lifted to the ceiling and tang 35 is inserted in aperture 34 of bracket 28 to form a pivotal connection for suspending the assembly. The bracket and foot are preferably secured respectively to the housing and shell of the fan assembly in such a manner that the lead-in Wires emerge from the assembly at a point beneath the outlet box so that short lead-in wires readily may be joined to the house circuit wires as at 22. Thus the air passageways within the housing are not cluttered with wires but are left free to permit a maximum volume of air flow.

After the electrical connections have been made, cover plate 26 is slid along the wires to a position in abutment with the inner wall of housing 10, covering the junction box. It is secured in this position as by screws or bolts 27. The fan assembly is then rotated upwardly about the hinge 13 until feet 14 reside above, and rest upon, feet 15 of the housing. Bolts 43 are then inserted through appropriate apertures in the feet 14 and elements 15'to secure the assembly in place. Finally a louver 44 is secured in place over the air inlet opening as by bolts 45 which engage the louver and mounting lugs 46.

When the housing interior and fan assembly require cleaning or repair the louver may be removed by loosening bolts 45. Next bolts 43 joining feet 14 and elements 15 are loosened and the fan hinge 13 permits assembly to be rotated downwardly into a dropped position below the housing. In the dropped position the interior of the housing and the various parts of the fan assembly are readily accessible and any parts needing replacement can be removed without the necessity of completely disconnecting the fan assembly from the house wiring circuit.-
