Definitions

  • the present invention relates to an improvement of a locking device for locking a lid of an opening / closing object having a lid (or door) such as a building, cabinet, or container to a main body of the opening / closing object.
  • Patent Document 1 An example of a prior art of a locking device that locks the lid of an openable / closable object on the main body of the openable / closable object is disclosed in Japanese Utility Model Laid-Open No. 3-92279, which is disclosed in Patent Document 1.
  • a case 2 attached to the main body, a locking bolt (locking body) 9 movably disposed in the case 2, and a lid (opening / closing body) 1 disposed between the case 2 and the locking bolt 9 is mounted on the main body ( In a state of being closed by the fixed frame body 5, the locking bolt 9 is urged so as to protrude from the case 2, and the spring 1 locks the lid 1 so as not to separate from the main body 5.
  • This locking tool includes a key (handle bar) 10 for displacing the locking bolt 9 from the locking position to the unlocking position or from the unlocking position to the locking position against the urging force of the spring 7.
  • the key 10 includes a cam 14 for inserting the shaft rod into the case 2 and displacing the locking bolt 9 in the unlocking direction (see Patent Document 1).
  • this prior art locking device has a lid 1 attached to a lid 1 so that the key 10 can be stably rotated in the case 2 of the locking device. It was necessary to have a bearing cylinder (guide cylinder) 4 extending in the thickness direction and guiding and bearing the shaft rod of the key 10.
  • the locking device according to the prior art can be effectively used for an opening / closing object having a thin lid, although the lid 1 can be effectively applied to an opening / closing object having a thick lid. This is difficult, and requires a key rotation support means on the lid side, resulting in a complicated structure.
  • the problem to be solved by the present invention can be effectively applied to an opening / closing object having a thin lid (or door), and provides a locking device that does not require a key support means on the lid side. It is in.
  • the problem-solving means of the present invention includes a locking case attached to either a lid (or door) or a main body of an opening / closing object, a locking bolt disposed in the locking case so as to be movable back and forth, and the locking bolt to the locking case.
  • the present invention provides a locking device characterized in that it has shaft flanges above and below the cam, and the upper and lower shaft flanges are rotatably held by a support portion of the locking case.
  • the support portion that supports the upper and lower shaft flange portions of the key can be provided at an arbitrary position such as an intermediate wall of the lock case.
  • these support portions are provided in the lock case. It is preferable to be provided on the upper and lower walls.
  • the locking bolt may have a key through-hole through which the shaft shaft portion of the key passes.
  • the key through-hole interferes with the advancement and retraction of the locking bolt. In order to avoid this, it is preferable to use a long hole.
  • the support portion that supports the upper shaft flange portion may be formed continuously with a cam through hole through which the cam of the key passes.
  • the key for locking and unlocking the locking tool is not supported by the opening / closing object, but is supported by the locking case of the locking tool, so that the key can be rotated in a stable state as in the prior art. It is not necessary to maintain a sufficient thickness on the lid of the opening / closing object so that the opening / closing object can be easily applied to an opening / closing object having a thin lid. Since there is no need to provide a supporting structure, the opening / closing object is not required to have a complicated structure, and can be applied to an opening / closing object of an appropriate form.

Abstract

Dispositif de verrouillage comportant : un boîtier de verrouillage fixé au couvercle d'un coffret ; un pêne de verrouillage disposé dans le boîtier de verrouillage et mobile dans les sens avançant et reculant ; un ressort qui sollicite le pêne de verrouillage de telle façon que le pêne de verrouillage dépasse de l'intérieur du boîtier de verrouillage et verrouille ainsi le couvercle de telle façon que le couvercle ne puisse pas être séparé du corps principal du coffret ; et une clé comprenant une came servant à déplacer le pêne de verrouillage d'une position de verrouillage à une position de déverrouillage contre la force de sollicitation du ressort. Le boîtier de verrouillage est fixé de façon à exposer le boîtier de verrouillage sur la surface extérieure du couvercle. La clé comporte une partie d'axe située au-dessus et au-dessous de la came et est guidée en rotation dans un trou d'appui pratiqué dans les parois supérieure et inférieure du boîtier de verrouillage, la clé étant par conséquent soutenue par le dispositif de verrouillage au lieu d'être soutenue par le couvercle du coffret.
