<p>The panel section (6) is positioned by springs when installed, pressing its upper edge against the front edge of the cover (3) for the machine casing. Each spring is arrange in a sleeve (19) and acts against a stud (12). The sleeve has a spring pressing against the free end of the stud, against the direction of insertion, and acting against the cover as described. The spring is formed on the sleeve, in unitary construction. On the side opposite the insertion opening, the sleeve has a plate which can move axially. A spring connected to the sleeve presses the plate against the free end of the stud. The spring is designed as a tension spring. It is wavy, in the shape of a number of connected S-sections. It is housed in a side recess of the sleeve. There are two such recesses, each containing a similar spring. The sleeve has a further spring pressing the stud horizontally towards the interior of the casing. This spring is a C-section cut from the sleeve casing and acting as a leaf spring. It presses against the front edge of the opening (18) in the folded edge (13) of the front wall (2) hence causing the inward horizontal force acting on the sleeve with stud inserted.</p> |
