Abstract
An insertion and removal system in a plug-in unit includes a handle-extension slide element inserted freely into the lever part in an advanced or retracted direction to slide in a longitudinal direction of the lever part between an extension position extended from a length of the lever part at the maximum and a retracted position substantially corresponding to the length of the lever part and a locking element arranged on the handle-extension slide element and the front panel, the locking element for locking the handle-extension slide element being slidable to the retracted position on the front panel.
Claims13
An insertion and removal system in plug-in unit, comprising:
- a front panel arranged on a plug-in unit insertable into a sub-rack, the front panel covering an opening frame of the sub-rack when the plug-in unit is inserted into the sub-rack, said front panel having a projection positioned thereon;
- a handle element including
- a lever rotationally supported on an end of the front panel and rotationally operated in one of a direction of insertion and a direction of removal of the plug-in unit with respect to the sub-rack, and
- an engagement part for engaging with said projection positioned on the opening frame of the sub-rack for transferring a rotational force of the lever upon rotationally operating the lever towards the projection,
- a handle-extension slide element slidably mounted on the lever for being movable in a longitudinal direction of the lever between an extended position of the lever for extending the length of lever to a maximum and a retracted position for reducing the length of the lever;
- and
- a locking element positioned on the handle-extension slide element for engaging the projection on the front panel, the locking element locking the handle-extension slide element in position on the front panel in the retracted position of the lever.

An insertion and removal system in plug-in unit, comprising:
- a front panel arranged on a plug-in unit insertable into a sub-rack, the front panel covering an opening frame of the sub-rack when the plug-in unit is inserted into the sub-rack, said opening frame having a projection positioned thereon;
- a handle element including
- a lever rotationally supported on an end of the front panel and rotationally operated in one of a direction of insertion and a direction of removal of the plug-in unit with respect to the sub-rack, and
- an engagement part for engaging with said projection positioned on the opening frame of the sub-rack for transferring a rotational force of the lever upon rotationally operating the lever towards the projection,
- a handle-extension slide element slidably mounted on the lever for being movable in a longitudinal direction of the lever between an extended position of the lever for extending the length of lever to a maximum and a retracted position for reducing the length of the lever;
- and
- a locking element including an engagement recess formed in the lever for engaging the projection arranged on the front panel, the projection engaging with the engagement recess when the lever part is rotated toward the front panel side, for locking the lever part on the front panel by transferring a stress generated in the lever part to the engagement recess as a force for narrowing an opening diameter of the engagement recess and for locking the lever on the front panel.

- an engagement part for engaging with said projection positioned on the opening frame of the sub-rack for transferring a rotational force of the lever upon rotationally operating the lever towards the projection,
- a handle-extension rotation element rotationally supported on the lever for rotationally moving in a longitudinal direction of the lever part between an extended position of the lever upon extending the lever to maximum length and a retracted position of the lever;
- and
- a locking element positioned on the handle-extension rotation element and the front panel, the locking element locking the handle-extension rotation element, upon being rotationally moved to the retracted position, on the front panel.
