  • the angular orientation of the shaft connector 64 relative to the bracket 62 can be adjusted without dissembling any parts of the mount 60 .
  • a pivot kit 80 is also installed between the door leaf 71 and the door frame 72 .
  • the pivot kit 80 comprises a pivot mount 82 concealedly mounted in the bottom side of the door leaf 71 , and a pivot 84 concealedly mounted in the bottom inner side of the door frame 72 and pivotally connected with the pivot mount 82 .
  • the axis of the pivot 84 is in alignment with the axis of the turnable shaft 54 of the door closer 50 in a line, such that the door leaf 72 is double-swingable about the axis of the turnable shaft 54 upon receiving an external pull or push force thereon.
  • the fixation casing 52 When the door leaf 71 receives an external force for clockwise or counterclockwise swinging the door leaf 71, the fixation casing 52 will turn along with the door leaf 71 about the shaft 54 because the turnable shaft 54 is now motionless relative to the door frame 72 , resulting in that the sector gear portion 542 of the turnable shaft 54 will be engaged with one of the linear gear portions 564 of the driven member 56 to drive the driven member 56 to move towards the driven position P2 and compress the spring member 58 . As soon as the external force is released form the door leaf 71 , the spring rebound force of the spring member 58 will forcedly move the driven member 56 back to the initial position P2, which means that the door leaf 71 will reversely swing about the shaft 54 back to its initial, force free position.
  • the driven member 56 has two face-to-face linear gear portions 564 , no matter the door leaf 71 is swung clockwise or counterclockwise the driving sector gear portion 542 of the shaft 54 will be definitely engaged with one of the linear gear portions 564 to make the door leaf 71 be double-swingable and then returnable back to its initial, force free position.
  • the door closer kit 40 of the present invention adopts the locating device 68 to adjust the angular orientation of the door leaf 71 relative to the door frame 72; therefore, the door closer is not limited to the linear gear driven type as the above embodiment described.
  • the door closer can be of any kind as long as it can be concealedly mounted in the door frame and has a turnable shaft connectable with the shaft connector of the mount.
