Anti-lift system, floor part, scaffold, and use

An Anti-lift system for a floor part for a scaffold, comprising:

• an end piece configured to form a longitudinal end of a floor part for a scaffold, provided with one or more hook elements with which the floor part at the longitudinal end can be hooked to a transverse ledger of the scaffold so as to be supported on that transverse ledger, wherein the hook elements define a ledger receiving space for the transverse ledger, in which ledger receiving space the transverse ledger is received when the floor part is hooked with the hook elements to the transverse ledger;
• and
• a stiff bolt couplable with the end piece, which in coupled condition is movable relative to the end piece along a bolt movement path between a releasing position and a locking position, wherein the bolt in the locking position extends along the ledger receiving space to block movement of a received transverse ledger out of the ledger receiving space, wherein the bolt in the releasing position extends less or not along the ledger receiving space to release movement of the received transverse ledger out of the ledger receiving space,
• wherein the anti-lift system is configured to have the bolt in coupled condition automatically move to the locking position when the bolt is between the locking position and the releasing position, at least when the transverse ledger is received in the ledger receiving space,
• wherein the anti-lift system further comprises a resistance element which is configured to provide a resilient resistance to counteract movement of the coupled bolt from the releasing position to the locking position so as to at least selectively stabilize the releasing position, wherein the resilient resistance can be overcome when the bolt is actively moved to the locking position by a user with a hand or a foot, wherein the resistance element comprises a leaf spring,
• wherein the bolt extends between a blocking end and an operating end, wherein the blocking end in the coupled condition is movable along the ledger receiving space by moving the bolt along the bolt movement path between the locking position and the releasing position,
• wherein the operating end in the coupled condition is at and/or above an upper side of the end piece so as to be accessible at that upper side for operation, both in the locking position and in the releasing position,
• wherein, in the coupled condition, both in the locking position and in the releasing position, the bolt extends between the blocking end and the operating end through an opening formed in the end piece at the upper side of the end piece,
• wherein the resistance element is fixedly connected with the bolt and configured for engagement with the end piece,
• wherein the resilient resistance to counteract movement of the coupled bolt from the releasing position to the locking position is provided by resilient engagement of a first portion of the resistance element with the end piece at the opening,
• wherein the resistance element is furthermore configured, in the coupled condition, to counteract uncoupling of the bolt with respect to the end piece by upward abutment of a second portion of the resistance element against the end piece, and
• wherein, both during the resilient engagement of the first portion with the end piece and during the abutment of the second portion against the end piece, the resistance element extends through the opening such that the first portion and the second portion are on mutually opposite sides of the opening.
