Field of the Invention The present invention relates to a fan system for mounting blade iron blocks and blades, and more particularly to a system for vibration isolation of ^=. Blades and Drive Motors for Ceiling Fans [Prior Art] There are many different types of fans today, such as ceiling fans, table fans, floor-to-ceiling fans, and fans used in conjunction with mechanical equipment. Most of these fans include blades and blade mounts or blade irons that connect the blades to the motor. Electric ceiling fans usually have a fixed outer casing 7 mounted from the ceiling (four): up. In operation, the motor rotates in the form of a blade mount or blade iron: an annular array of individual extensions. Each blade iron block is combined with a blade mounted thereto. = Mounting the sling iron to the motor blade to the blade iron by having the mounting screw (4) pass through the hole in the blade and into the threaded hole in the blade iron. The leaf ceiling fan then transmits the noise caused by the motor, because the area and degree of the blade are large, the blade tends to act as a resonance or sound transmission device, and thus tends to transmit the noise, vibration, etc. received by the blade from the drive motor to The air motor drive motor itself is relatively quiet, but when used to drive the ceiling fan blades, the irritating noise can be transmitted to the circumferential ring via the blades. Thus, for example, caused by a slightly loose stator lamination Noise is fixed, the singer, the gossip that produces the gossip is relatively unpleasant and unobtrusive, and sometimes can be transmitted through the motor structure, through the blade mounting box or to 139379.doc 200949079. Similarly, 'and become aroused' arrives at the leaf > ι itself, and produces annoyingly high noise rotor vibrations or arm sounds as well as pumping noise that may be augmented by the blades. See 'There is still a need for a feather that limits the transmission of noise to the rotating blades'. Thus, the present invention is primarily directed to providing such a ceiling fan system. SUMMARY OF THE INVENTION In a preferred form of the invention, a fan includes: an electric motor; an annular array of blade iron blocks; and a ceiling fan blade that is combined with each of the blade iron segments of the blade array. Each blade iron block has at least one mounting aperture therein and a resilient grommet ring positioned within the mounting aperture. Each of the blade iron segments in the array of blade iron pieces is transferred to the other two of the array of blade iron blocks that are placed opposite each other. [Embodiment] Referring next to the drawings, a ceiling fan 1 is shown having an electric motor 13 connected to a power source by a wire not shown. Motor 13 includes a bottom mounting plate 14 that is consuming to the rotor for rotation during operation of the motor. The motor bottom mounting plate 14 has an annular array of threaded mounting holes 19. The ceiling fan also includes an annular array of blade iron blocks 16 coupled to the mounting plate 14 each having a blade 17 mounted thereto in a conventional manner. Eight per blade iron has a motor mounting flange 21 that is configured to interface with the bottom mounting plate 14 (four) of the motor 13. Each of the mounting flanges (4) has a recess or recess 23 extending from the bottom surface 24 and the inner surface 25, an end tongue 26, and an end recess 27 configured to receive the end tongue 26. . The end groove portion 27 includes an alignment pin 28 and a threaded mounting hole 29. End tongue % 139379.doc 200949079 匕任. 蚵平川川, which is configured to accommodate the groove portion alignment pin 28; and a cone hole 31 that is aligned with the mounting hole 29. The threaded mounting screw 32 passes through the tongue-shaped 4 taper hole 31 and is screwed into the groove portion mounting hole 29. Thus, each mounting flange 21 is flanked by its two oppositely disposed and adjacent mounting flanges η, with the tongue and groove portions providing limited movement therebetween. The recess 23 extends from the bottom < the face 24 a distance less than the total thickness of the mounting flange and thus leaves a relatively thin portion 35 of the flange. The recess 23 also includes a semi-circular inwardly directed aperture or slot 38 that blocks the inner surface rim 25 at the relatively narrow throat 39. The slot 38 is generally aligned with the threaded mounting (four) of the bottom mounting plate 14. The resilient suspension member in the form of a rubber grommet 40 is configured to be generally received in a concave π plus, and in particular, on a thinner portion 35 within the (4) 38. The grommet 40 has a generally cuboid shape and has an inner gap opening 42 extending axially therethrough. The side walls of the grommet 40 are provided with relatively outwardly open recesses 44 that are proportioned to accommodate installation at the slots 38 when the grommet is pressed into position and secured in the recess 23 Flange points • 35. When the grommet is so secured, a portion of the grommet extends partially below the recess 23, but the axial thickness of the grommet 40 is such that the portion extending into the recess is completely contained within the recess. Another portion of the grommet 40 extends over the upper surface of the mounting flange when the grommet is inserted. The narrower throat 39 tends to hold the grommet in place. The opening 42 in the grommet is adapted to receive a threaded headed thread 5 turns, the thread 50 being partially threaded only at its outer end 52. The threads are intended to be received in one of the mounting holes 19 of the mounting plate 14. The bolt 5〇 extends into the mounting plate to only reach a predetermined depth defined by the depth of the thread 52, and when the screw 139379.doc 200949079 椿50 is inserted through the grommet opening 42, the mounting flange 21 is suspended from the thread The enlarged head 51 is below the mounting plate. Preferably, the grommet ring 4 is not in direct contact with the mounting plate 14. The grommet 40, together with the thread 50, provides a means for suspending the blade iron 16 from the motor mounting plate 14, thereby eliminating metal to metal contact. The entire weight of the fan blade 17 and the blade iron block 16 is carried on the thread 5 by elastic coupling defined by the grommet ring 4'. The enlarged head 51 of the thread is received adjacent the outer surface of the adjacent grommet 40, and thus the weight of the blade iron and the blade is typically transmitted to the head of the thread via the grommet 40. The connected blade iron block and the locked grommet 40 are free to slide up and down slightly on the threaded thread. The purpose of the slight axial freedom of movement is to provide complete isolation of the blade iron block from the mounting plate 14. It should be understood that the present invention provides an elastic attachment between the blade iron block 16 and the motor mounting plate 14 that is free of any metal to metal contact. Any vibration in the motor will tend to be absorbed in the grommet 4〇, effectively isolating the blade Η from the direct transmission of this vibration. It should be understood that the invention is not intended to be limited to ceiling fans and is equally applicable to all types of fans. It should also be understood that the invention is not limited to a certain number of blades or blade iron. Thus, it can be seen that a ceiling fan is provided which isolates motor noise and vibration in the fan. Although the present invention has been described in detail with reference to the preferred embodiments of the present invention, it is understood that modifications and modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims Many modifications, additions, and deletions, additions, and deletions.
