Abstract
A locking device for supporting members for a mobile machine, which supporting members are arranged on a chassis or load-bearing frame and can be extended, pivoted or telescoped from a retracted transport position into a deployed working position, has a locking bolt which can be displaced between a locked position and an unlocked position in a guide sleeve which is fixed to the frame and is arranged transversely with respect to the pulling-out direction of the supporting member, which locking bolt is prestressed in the direction of the locked position under the action of a spring, has an actuating member which displaces the locking bolt between the locked position and the unlocked position, and has a latching and guiding member for the locking bolt, which latching and guiding member is arranged rigidly on the supporting member, wherein the latching and guiding member has a guiding curve which pushes the locking bolt into a release slope, and wherein the locking bolt can be moved in the release slope automatically into the locked position thereof. In order for it to be possible to perform arresting of the supporting members in defined positions in the case of limited spatial conditions and only partially extended supporting members, the latching and guiding member extends between a first latching position for the locking bolt in the region of the retracted transport position of the supporting member and a second latching position for the locking bolt in the region of the completely extended, pivoted-out or telescoped working position of the supporting member, and the latching and guiding member has at least one further latching position between the first and second latching position.
