Definitions

  • the present invention relates to an insertion type buckle comprised of a female member and a male member, wherein the female member and the male member can be locked or sealed with a locking device or the like when the female member and the male member are engaged with each other by insertion.
  • a conventional insertion type buckle in which a male member is inserted into a female member has been widely used as a joint device for opening/closing an opening of a bag such as a nap sack or a binding device of a fastening belt for fastening commodities or traveler's bags.
  • this buckle allows users to engage/disengage the female member and male member easily, anyone can release the engagement so that there is a fear that if a bag having this buckle is left without owner's attention, somebody may release the engagement and steal its content or commodities from the bag.
  • a buckle which is structured to be locked so that the male member inserted into the female member may not be removed, has been well known.
  • a buckle which is disclosed in Japanese Utility Model Publication No.HEI7-46166 and shown in Fig. 34.
  • a locking cover 110 to guide engaging/disengaging operation is disposed slidably in a pressing plate 121 which is provided on a housing 103 of the female member 101 and can be pressed in order to release the engagement with a male member 102.
  • This locking cover 110 accommodates a rotor 112 which revolves eccentrically and slides the locking cover 110 back and forth when a key 111 is inserted and revolved into the rotor 112.
  • the pressing plate 121 cannot be pressed, and when the locking cover 110 is retreated, the pressing plate 121 can be pressed.
  • the engaging piece of the male member 102 releases engagement with an elastic engaging piece 101a of the female member 101 so that the male member 102 can be removed from the housing 103 of the female member 101.
  • said buckle 100 is a buckle in which, the locking cover 110 is mounted slidably through the rotor 112 on the pressing plate 121 of the housing of the female member 101. Therefore, the structure of the buckle 100 is very complicated and a large number of parts are required. Moreover, the special key 111 is necessary, thus an existing locking device such as a padlock or a cylinder lock cannot be used as the locking device of this buckle. Therefore, there is a problem that the cost of the buckle may be high.
  • UK patent publication No.2266337 discloses a buckle as shown in Fig. 35.
  • This buckle 120 engages when right and left inserting leg portions 122a of a male member 112 are inserted into a housing 121a of a female member 121.
