Patent ID: 7661776

Claim:
A fastening arrangement for detachably fastening a component to a frame part, the arrangement comprising: a frame part; a component; a means for pivoting pivotable to the frame part and arranged to turn about a pivoting axis between a normal position and a release position, a locking means comprising at least one centre pin provided in the means for pivoting, and at least one recess provided in the component and to receive the centre pin at least partly, the centre pin being movable in an opening direction away from the recess and in a closing direction toward the recess, the directions being mutually opposite and substantially parallel to the pivoting axis of the means for pivoting, the centre pin having an opening position whereby the centre pin is arranged to be outside the recess and a locking position whereby the centre pin is arranged to be within the recess, the centre pin being located substantially coaxially with the pivoting axis of the means for pivoting and having a free end which is bevelled and cooperates with the component such that when the component is pushed towards a position arranged in the frame part, the component co-operates with said free end of the centre pin moving the centre pin in the opening direction until the centre pin reaches the opening position which allows the component to be pushed into the position arranged in the frame part, the locking means further comprising return means arranged to bias the centre pin into the locking position if the centre pin is deflected from the locking position, such that when the means for pivoting is in its normal position, inserting the component into the position arranged in the frame part causes the component to be locked into the frame part; means for opening the locking comprise a cam surface provided in the means for pivoting, and a cam surface provided in the frame part, the cam surfaces being arranged to co-operate with each other to move the centre pin in the opening direction when the means for pivoting is pivoted from the normal position in the direction of the release position such that turning the means for pivoting from its normal position to its release position moves the centre pin from the locking position to the opening position thereby releasing the locking of the component in relation to the frame part and allowing the component to be detached from the frame part.
