CONSTRUCTIVE IMPROVEMENT TO AN ANTI -THEFT LOCK DEVICE APPLIED TO AUTOMOBILE TRUNKS

摘要

A constructive improvement to an anti-theft lock device applied to automobile trunks, whose innovative solution implies a new anti-theft lock (1) , applicable both to common trunk locks and to trunk locks having electric assembly elements, wherein said improvement provides greater productivity during the assembly of said item, in addition to providing greater reliability to the anti-theft safety system, and this is achieved thanks to a constructive concept wherein the anti-theft lock item (1) comprises a clench ring element (A) , sealing joint (B) , lock cylinder element (C) and fastening clinch element (D) . The clench ring element (A) comprises a hollowed latch area (Al) , an upper latch element (A2) and a lower latch element (A3) , also having a relief lock (A4) , in addition to structural grooves (A5) . In turn, the fastening clinch element (D) has upper (Dl) and lower (D2) latch ends, having an inflexion segment (D3) in its middle section, and both these elements are fitted into the lock cylinder element (C) . Once assembled, the anti-theft lock item (1) prevents the access of tools (4) to the bracing element (F) , thanks to the formation of a height barrier (Hl) , also generating a width (H2) which eliminates assembly gaps.
