This report presents the results for the enumeration of topologies of LVCB mechanisms and their associated DL-Reduced families. A DL-Reduced family is obtained by deleting bodies DL and fB and their connections and is useful for separating the main mechanism, including handle (H) and contacts carrier (CC), from the delatching mechanism. Graphs and sketches of the mechanisms are included in electronic format and are labelled using two ways. The first way assumes that the mechanism has a traditional delatching  submechanism where two bodies DL and LL are put in contact and then separated, a body fB between them emulated the DOF of the contact. The second way assumes that fB is also the body with the delatching function (DL) and the mechanism remains connected even when delatching. The body called rod (R) was also identified as the body connected to the handle. In some cases, the functionality of the LL or R can be superposed. Edges are assumed to be all of the revolute type and they are not labelled for the sake of clarity. The families of subatlases Ia and IIa have practical interest because the designer can add the delatching mechanism after designing the main parts (containing O, H, and CC). Families Ib and IIb are provided for classification purposes because the addition of the delatching bodies is not trivial (Informe CIMEC 171 realizado dentro del SAT UNL 537362, Contrato 2009-447-01).
