    摘要： The security reversible key with an assigned cylinder (Z) has a blocking groove (BN) with a coded blocking depth (B1, B2, B3), which runs parallel to the axis of the key (x) from the tip of the key to at least the first position (P1) of a row of tumbler pins (A2) on the key. In the assigned cylinder, at least at the rearmost coding position (P1), a pair of tumbler pins corresponding to the blocking groove (BN) with a blocking tumbler pin (BZ) and an extended blocking counter pin (BG) are foreseen, whereby the blocking counter pin (BG) impinges on the cylinder housing (10), if the blocking groove is insufficiently deep and, with this, the complete insertion of a key with an insufficiently deep blocking groove is blocked by the pair of blocking tumbler pins. Simultaneously, the blocking tumbler pin (BZ) with the counter pin (BG) at the position (P1) also serves as coding tumbler pin. In the case of the locking system with security reversible keys for locking installations at least two areas are defined, In a first area (G1) several additional security elements and a blocking code function are provided while, in the second area (G2), a more simple basic coding are foreseen. With the first area (G1), an unequivocal segmentation into independent market areas (M1, M2, M3) is defined and, with this, a world-wide unique locking system with enhanced security and applicability is created.

    摘要： A safety latch construction is disclosed, of the type which has a rigid, pivoted slot-providing member secured to the doorframe, and a runner secured to the door having a T-shaped projection which engages the slot when the safety latch is operative, thereby limiting the amount of door opening movement. All of the parts are formed by stamping processes. No casting or machining is required. The doorframe member includes (a) a supporting member secured to the doorframe and having integral flanges providing pivot apertures, and (b) a pivoted member having an elongated slot formed between metal side bars which have projecting pivot pins and which are spaced at their pivoted ends, the resiliency of the side bars permitting the pivoted member to be readily assembled to the supporting member. An additional locking member provides a deadbolt feature.
