Abstract:
1. A device for detachably securing a dust filter bag in dust aspirating equipment, the equipment having a bag wall, comprising a flange part of rigid material seated externally on the bag wall and having a passage opening aligned with an inlet opening in the bag wall, and an adapter plate of rigid material, which is able to be secured to the dust aspirating equipment and is able to be detachably connected with the flange part by means of a plug and detent joint, the adapter plate having a through opening which in the connected state is flush with the passage opening in the flange part and together with said passage opening in the flange part constituting a flow opening and an annular seal effective in the connected state between the adapter plate and the flange part for peripherally sealing off the through opening from the outside, wherein the flange part radially outside the annular seal in a position inclined away from the adapter plate, is able to be plugged to the adapter plate and in the plugged state is connected with the adapter plate so that the flange part is able to be pivoted toward the adapter plate into a position of use connected by detent means with the adapter plate and arranged coaxially in relation to the adapter plate, in which position a sealing face on the flange part or of the adapter plate is held against the annular seal arranged on the adapter plate or, respectively, the flange part, wherein for pivotal mounting of the plugged on flange part at least one pivot axle part is arranged on the flange part or on the adapter plate such pivot axle part being provided with a female socket on the adapter plate or, respectively, on the flange part, wherein with the pivot axle part arranged on the flange part the pivot axle part, in the plugged state, fits behind a support part on the adapter plate and delimiting the female socket, arranged on the adapter plate, in a direction away from the adapter plate, or wherein with the pivot axle part arranged on the adapter plate the socket part is formed by a hooked suspending part on the flange part, which in the plugged on condition fits behind the pivot axle part on the side facing the adapter plate, and wherein a detent member is mounted in a moving manner on the adapter plate or on the flange part, such member fitting, in the position of use, behind a detent projection with detent engagement, such projection being arranged on the flange part or, respectively, on the adapter plate.
