Abstract:
A ceiling fan includes a motor, a bracket unit connected fixedly on the motor and including a plurality of angularly spaced-apart blade-installation members, a plurality of blades and a mounting unit. Each blade has a locking segment registered with a respective one of the blade-installation members and a covering wing registered with a respective one of the blade-installation members. The locking segment and the covering wing of each of the blades are registered with two adjacent ones of the blade-installation members. The mounting unit includes a plurality of fastener sets, each securing the locking segment of a respective blade to a corresponding blade-installation member, and having a bottom end that is covered by a corresponding covering wing.
Abstract:
A canopy assembly includes a bracket, a canopy, a plurality of screws, two biasing members and an annular decorative ring. The canopy has two locking sections and two installation sections. Each of the installation sections has a limit wall and an abutment wall connected to the limit wall and cooperating with the limit wall to define an installation groove. Each of the biasing members includes an elastic plate engaging a respective one of the installation grooves and a protrusion formed on the elastic plate. The annular decorative ring covers the screws and has two engaging segments. Each of the engaging segments is formed with a groove engaged with the protrusion of a respective one of the biasing members.
Abstract:
A detachable blade and support assembly for a ceiling fan includes a support having an insert groove, a blade having an insert end portion inserted into the insert groove and having two retaining grooves formed respectively formed in two opposite side surfaces, and a mounting unit connecting the blade to the support. The mounting unit includes two side resilient members disposed on the support and having engaging portions engaging respectively and fittingly the retaining grooves in the support to retain releaseably the insert end portion of the blade in the insert groove in the support, a centrifugal resilient member for preventing the engaging portions of the side resilient members from movement in the retaining grooves in the blade.

Abstract:
A DVD navigation system comprises a plurality of navigation modules and a utility. Each navigation module comprises a check function determining data correctness of tables corresponding to the respective navigation modules. Each navigation module generates a read table request. The utility receives the read table request, reads at least one table identified by the read table request from at least one IFO file in a file system, and checks data correctness of the table by using the check function. If the data of the table is incorrect, the utility reads the table from at least one backup file of the IFO file in the file system, and transmits the data to the navigation module for decoding.
