Abstract

Mounting apparatus for an irradiation device, such as a sunlamp or the like, wherein a mounting bracket pivotally supported on a frame has an irradiation device operatively supported thereon and wherein a drive motor pivotally moves the mounting bracket relative to the frame. A connection mechanism interposed between the drive motor and the mounting bracket includes bearing recesses formed in the mounting bracket, a lifting nut having a pair of articulated pins engaging in the bearing recesses and a lifting spindle driven by the drive motor and having the lifting nut operatively mounted thereon. A mechanically actuated release lever engages the lifting spindle for moving the articulated pins out of engagement with the bearing recesses, and a spring interposed between the frame and the mounting bracket applies a spring biasing force pivotally urging the mounting bracket in a direction for lifting the mounting bracket when the articulated pins are moved out of engagement with the bearing recesses.

Claims

1. Mounting apparatus for an irradiation device, such as a sunlamp or the like, comprising:

frame means;

a mounting bracket pivotally supported on said frame means adapted to have an irradiation device, such as a sunlamp or the like, operatively supported thereon;

a drive motor for pivotally moving said mounting bracket relative to said frame means;

connection means interposed between said drive motor and said mounting bracket, said connection means comprising bearing recesses formed in said mounting bracket, a lifting nut having a pair of articulated pins engaging in said bearing recesses and a lifting spindle driven by said drive motor and having said lifting nut operatively mounted thereon;

a mechanically actuated release lever engaging said lifting spindle for moving said articulated pins out of engagement with said bearing recesses;

first spring means interposed between said frame means and said mounting bracket applying a spring biasing force pivotally urging said mounting bracket in a direction for lifting said mounting bracket when said articulated pins are moved out of engagement with said bearing recesses;

said bearing recesses being formed with locking slots directed vertically relative to the releasing movement of said articulated pins of said lifting nut, said articulated pins entering into said locking slots so as to stop under the influence of said first spring means insofar as said irradiation device is not mounted on said mounting bracket; and

second spring means acting on a pawl articulated at said mounting bracket when said irradiation device is mounted at said mounting bracket, in the lowered position of said irradiation device in such a way that said pawl is swivelable and moves said articulated pins of said lifting nut out of said locking slots in the releasing position.

2. Apparatus according to claim 1, wherein a stop member is provided defining the limit of the swiveling movement of said pawl, which swiveling movement is effected under the influence of said spring means in such a manner that said articulated pins of said lifting nut are located exactly in said release position.
