  • Patent number: 6955069
    Abstract: In the handle assembly, a combination lock (6) is disposed adjacent to a cylinder lock (13) in the handle (2). A locking plate (11) is interlocked with a rotor (8) of the lock (13), and it engages with a shoulder (15) of a receiver lever (16), which is a intermediate actuating member, so that the door handle (2) is held in its folded position. When the combination lock (6) is held in its unlocked condition and the handle (2) is pulled, the receiver lever (16) is swung upward by the locking plate (11) to release the handle (2) from the body (1). Each of the predetermined mark of each of the marked dial discs (4) for unlocking is detected by turning each of the marked dial discs (4) until the resetting member (72) is brought into engagement with each of the detecting grooves (71).

  • Patent number: 6755063
    Abstract: In a side bar cylinder lock with a variable key code, plug (6) engages within casing (1) at two opposite portions in preventing plug (6) from rotating in locking state. This improves the lock in resistance to attack. Plug (6) has holes (8) each receiving a tumbler plate (11) and variable tumbler (14) side by side therein. When plug (6) is rotated to have a bulged portion (21) of said bar holder (19) abut against concave portion (2) of casing (1), spring (25) forces end portion (26) of plate (11) to enter receiving hole (9) of plug (6), and forces a bulged portion (21) of holder (19) to engage with concave portion (2) of casing (1), whereby engaging portion (13) of plate (11) is disengaged from an engaged portion (15) of variable tumbler (14). After such disengagement, variable tumbler (14) is rotated through an angle to change the key code to a new one.
