发明名称 Torsion spring mount for suspended ceiling panels
摘要 The present invention provides an improved frame clip arranged and constructed to be easily field-mounted and/or reconfigured on a panel frame such as those used to form suspended ceilings. By allowing the installation of the frame clips to be deferred until the panels are being installed, the frame clip permits the panels to be shipped without frame clips and/or attachment hardware, such as torsion springs, installed, thereby reducing the likelihood of shipping damage.
