Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over CN 110499958 (CN 958) in view of EP 0682167 to Udo et al (Udo). PNG media_image1.png 438 621 media_image1.png Greyscale Regarding claims 1 and 8, CN 958 discloses a security system for locks. The lock is equipped with a bolt (5). The security system comprises a closed-door detector (11) configured to move linearly when activated by an external element, and an anti-tamper cam (20) configured to be situated either in a first non-locking position or in a second locking position, such that the anti-tamper cam is situated in a second locking position when the closed-door detector moves linearly by making contact with the external element, preventing the bolt from opening. The security system further comprises a locking element (27) configured to rotate around a second axis of articulation, the hinged locking element being provided with a locking portion configured in such a way that when the hinged locking element rotates around the second axis of articulation, said locking portion acts as a stop for the bolt, preventing the opening thereof. CN 958 fails to disclose that the locking element is hinged. CN 958 just discloses that the locking element rotates. PNG media_image2.png 387 625 media_image2.png Greyscale Udo teaches that it is well known in the art to provide a hinge (10) to a locking element (9) for rotatably support the element. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the locking element described by CN 958 with a hinge, as taught by Udo, in order to rotatably support the element. As to claim 2, CN 958 discloses that the anti-tamper cam (20) is configured to rotate around a first axis of articulation. PNG media_image3.png 441 471 media_image3.png Greyscale As to claim 3, CN 958 illustrates that the locking element is dimensioned to comply with the following geometric condition: H × L 2 > R × L 1 wherein: (H) is the distance within which the anti-tamper cam locks the bolt; (R) is the distance that the hinged locking element must travel to lock the bolt; (L1) is the distance between the first axis of articulation and the first point of contact of the anti-tamper cam and the bolt; and (L2) is the distance between the second axis of articulation and the first point of contact of the locking portion and the bolt. As seen above, R is smaller than H, and L1 is approximately the same as L2, so then CN 958 is configured to comply with the equation. Applicant is reminded that a change in the size or shape of a prior art device is a design consideration within the skill of the art. As to claim 4, CN 958 illustrates that the following geometric condition is also configured to meet: A>B wherein: (A) is the distance the bolt travels until it is locked by the hinged locking element; and (B) is the distance the bolt travels until it is locked by the anti-tamper cam. As to claim 5, CN 958 illustrates that the following geometric condition is also configured to meet: A × H × L 2 > R × B × L 1 . As to claim 6, CN 958 illustrates that the centre of gravity of the hinged locking element is situated outside the second axis of rotation (not in the axis). As to claim 7, Udo teaches that the locking element (9) is spring-loaded (spring 11).
