Apparatus for detachably mounting electrical assembly units to supporting panels

An apparatus for detachably mounting an electrical assembly unit to a panel, comprising:

• a supporting frame adapted to be attached to said panel prior to the mounting of the electrical assembly unit;
• a manipulating rod provided rotatably in said supporting frame and extending in the direction along which said unit is mounted or removed;
• pressing means mounted on said manipulating rod movably axially of said rod upon rotation thereof;
• and
• engaging means fixedly provided on said electrical assembly unit in a position to be engaged by said pressing means,
• said manipulating rod being so arranged that the rotation thereof causes movement of said pressing means to bear pressingly against said engaging means, whereby said electrical assembly unit is forcefully moved either to a mounted or clamped position or to a detached position in dependence upon the direction of rotation of said rod, said rod having a head which projects outwardly from said supporting frame, said head serving as a means for receiving a manipulating tool for rotating said rod and at the same time as an indexing means in cooperation with a hole formed in said electrical assembling unit to facilitate the positioning of said unit when said unit is to be mounted.

An apparatus for detachably mounting an electrical assembly unit to a panel, comprising:

• a supporting frame adapted to be attached to said panel prior to the mounting of the electrical assembly unit;
• a manipulating lead screw provided rotatably in said supporting frame and extending in the direction along which said unit is mounted or removed;
• pressing means including a nut portion threadedly mounted on said manipulating lead screw movably axially of said lead screw upon rotation thereof and at least one projecting portion laterally extending from said nut portion;
• engaging means fixedly provided on said electrical assembly unit in a position to be engaged by said projecting portion of said pressing means;
• said nut portion being threadedly mounted on said lead screw so tightly that said nut is enabled to rotate together with said lead screw to such an angular position that said projecting portion is adapted to bear against said engaging means;
• and
• said manipulating lead screw being so arranged that the rotation thereof causes movement of said projecting portion of said pressing means to bear pressingly against said engaging means, whereby said electrical assembly nut is forcefully moved either to a mounted or clamped position or to a detached position in dependence upon the direction of rotation of said lead screw.

An apparatus for detachably mounting an electrical assembly unit to a panel, comprising:

• a supporting frame adapted to be attached to said panel prior to the mounting of said electrical assembly unit;
• a partly outer threaded manipulating rod mounted threadedly in said supporting frame so as to be axially displaced upon rotation thereof in the direction along which said electrical assembly unit is mounted or removed;
• pressing means mounted on said manipulating rod axially unmovably relative to said rod;
• engaging means fixedly provided on said electrical assembly unit in a position to be engaged by said pressing means;
• and
• said manipulating rod being so arranged that the rotation and therefore the displacement thereof causes movement of said pressing means to bear pressingly against said engaging means, whereby said electrical assembly unit is forcefully moved either to a mounted or clamped position or to a detached position in dependence upon the direction of rotation of said rod.
