Problem Statement

  • Conventional ceiling fan coupling arrangements easily support the weight of an average person during hanging., posing a serious risk for self-harm and suicide
  • This vulnerability highlights a critical safety concern, necessitating the development of reliable safety device that effectively addresses the risk of hanging from ceiling fans, ensuring enhanced security and prevention measures.

Technology

  • The present invention discloses a  safety device to prevent overload of a suspension arrangement of a ceiling fan, main components  are:

  • While installing, the top mount tube is attached securely to the ceiling using a bolt through the said  diametrical hole
  • The  bottom mount tube is configured to be placed within the top mount tube , a top portion of the bottom mount tube having a plurality of slits forming a flared portion
  • The said series of slits engages with the tapered portion of the top mount tube for a secure fit
  • These slits allow for controlled deformation of the tube under excessive load conditions
  • Upon application of a load above a threshold value, the slits are configured to close and allow the bottom mount tube to pass through the bottom portion of the top mount tube, thereby disengaging the suspension arrangement.
  • The threshold value above which the slits are configured to close is 25kg.
  • The top mount tube and bottom mount tube are further connected using a metal wire which prevents the ceiling fan from falling after the suspension arrangement disengages.

Key Features/ Value Proposition

Technical Perspective:

  • The said safety device prevents overload of a suspension arrangement of a ceiling fan
  • The arrangement of slits and the flare is configured such that the flare elastically deforms to release the bottom mount tube from the top mount tube.
  • After the device releases due to application of a load above the threshold value, it is easy to reassemble to restore the safety coupling.

User Perspective:

  • The said safety device provides means for safe coupling of a ceiling fan without the need for complex and expensive arrangements such as springs.
  • The release arrangement is also highly reliable because of its simplicity, and inexpensive
  • The safety wire prevents accidents due to falling of the fan.
