Definitions

  • This invention relates to a versatile flexible fan mount for mounting a fan or other device on a chassis, and more particularly, for example, to such a mount for electronic and other equipment where a fan is used to ventilate a heat producing structure, such as a computer or the like.
  • such a device may be mounted by means of bolts or other fasteners for connecting a frame to a panel or chassis to which it must be connected.
  • the frame and chassis vary within limited dimensions from manufacturer to manufacture, and a variety of sizes is usually required for installation.
  • rigid mounting of the device on the chassis can result in making the fan or other device inoperable or causing it to short, particularly if the mount is fabricated from conductive material, such as metal.
  • conventional devices require time and effort to assemble, since many comprises two pieces which must be connected during installation, and that requires extra effort and cost in assembling such devices on a chassis, as well as a the necessity of maintaining a variety of parts and parts inventory.
  • a flexible mounting device is provided.
  • This device is not only flexible, but it also has a structure which can accommodate chassis and frame holes of varying sizes, and where the fan or other device is intended to be mounted in various positions relative to the chassis on which it is mounted.
  • the instant device also is fast and easy to install, and a variety of parts inventory is not required to accommodate variations in mounting requirements.
  • a mounting device embodying the present invention comprises a resilient stud, preferably fabricated from silicone rubber or the like, which is of a durometer permitting it to be extended or stretched for entry into apertures on a frame and chassis.
  • the stud has a number of axially arranged enlarged undulations or ribs which can be drawn into the apertures when the mounting device is stretched and when relaxed can effectively hold the fan or the like in place.
  • Mounts for fans and similar devices must meet critical acoustic and vibration standards. These mounts must be used in such a way that no adverse vibration is caused to the fan or the like and its mounting panels, and the flexible mount embodying the present invention meets such standard and does not cause unwelcome vibration or sound problems.
  • the mount embodying the present invention also comprises electrical insulating material, so that undesirable shorting between the mount and its housing is not possible.
  • the novel mounting device embodying the invention has a break-away end and a medial portion with an enlarged section having a diameter greater than the chassis aperture into which it is inserted, which permits the end adjacent to its panel to be broken away from the stud to provide a neat end for the installation after the fan frame or similar member has been secured to the chassis.
  • This arrangement also provides a spacer between he chassis and the frame or housing for resiliently and securely mounting the fan or other device on the chassis.
  • Another object is to provide a shaft-like novel mounting device with axially extending enlarged undulations.
  • Another object is to provide a .novel mounting device which can be stretched, inserted into and secured in corresponding apertures in a chassis and frame.
  • Another object is to provide a novel mounting device for a fan or the like which has a break away head on a shaft which can be removed so the mounting device installation is attractive.
  • Another object is to provide a novel mounting device which has integral spacer means for securing a member such as a fan spaced apart from the chassis.
  • Another object is to provide a novel fan mount which has a shoulder adapted to prevent contact between a frame and the panel to which it is mounted.
  • Another object is to provide a novel mounting device which has a break-away grip usable for easy manipulation of the mounting device into a frame or housing and chassis and which is adapted for severing from the mounting device after it has been installed in connecting the frame or housing to its chassis.
  • Another object is to provide a novel mounting device which is easy to manufacture and use and efficient to install and use.
  • Figure 1 is a perspective view of one embodiment of the mounting device showing the connection of a fan frame to its chassis by means of the novel mounting device embodying the invention.
  • Figure 2 is a side elevational view of the mounting device shown in Figure 1.
  • Figure 3 is an end view of the mounting device shown in Figures 1 and 2.
  • Figure 4 is a detailed sectional view of the enlarged undulations on the mounting device embodying the present invention
  • FIG. 5 is a perspective view of another embodiment of the mounting device showing the connecting of a fan frame to its chassis by means of the novel mounting device embodying the invention.
  • Figure 6 is a perspective view on a fan frame connected to its chassis showing the novel mounting device in place, with one such mounting device having its break away grip connected and another grip severed from the mounting device.
  • Figure 7 is a side elevational view of the mounting device shown in Figures 5 and 6.
  • Figure 8 is a detailed sectional view of the break away grip for the modified mounting device. Description of Preferred Embodiments
  • a typical frame F is attached to a chassis or panel C by means of a mounting device 10 embodying the present invention.
  • the frame F and the panel C have corresponding apertures Al and A2 for receiving the mounting device 10.
  • the frame F may contain a fan B which is subject to vibration and requires a resilient mounting system.
  • the mounting device 10 is preferably molded from silicone rubber and is longitudinally stretchable.
  • This mounting device 10 is preferably formed with a series of enlarged axial spaced undulations 11 having a diameter greater than the apertures Al and A2 of the frame F and chassis C, and a shaft 12 of the mounting device 10 is substantially the diameter of these apertures Al and A2.
  • the forward face 14 of these undulations 11 is preferably tapered toward the shaft 12, and the mounting device 10 is stretchable sufficiently to permit the undulations when stretched to pass through the apertures Al and A2, but when relaxed to grip the walls W surrounding the apertures.
  • the end of mounting device 10 remote from the shaft 12 preferably comprises an axially arranged enlarged disc 15 which has a diameter greater than the shaft 12, and which is spaced apart from an enlarged head 16, which has a diameter greater than the disc 15.
  • This arrangement permits the head 16 to fit against one side of the chassis C and the other side to be spaced apart and abutted by the disc 15.
  • the modified mounting device 20 is similar to the mounting device 10, except it has a break away grip 27 formed on its head 26.
  • the grip 27 and its head 26 are connected by a web 28, which when bent will sever from the head, leaving a neat appearance of the installation.
  • the remote end of the shaft 22 of this embodiment may be rounded at 29 to permit its easy insertion into the apertures Al and A2.
  • each enlarged undulation 11 is substantially perpendicular to the shaft 12 or 22.
