During the assembly, the first end portion 108 is inserted through the lower opening 88 of the mounting plate 72, and is thus rotatably supported. The retaining ring 84 is inserted into the snap-ring groove 112 to retain the lower cam arm 76 in rotatable attachment with, ie, it is rotatably coupled with the mounting plate 72. After the final fixing of the chassis Connected 14 to the door 12, the mounting portion 114 of the interior operator 66 is received in an aperture 116 of the hollow axial arrow 106, and fixed and secured thereto by fixed screws 118a, 118b. The configuration of the outer operator 18 and inner operator 66 is such that the lower cam arm 76 can rotate about its rotational axis Z2 by a corresponding rotation of the inner operator 66, but the lower cam arm 76 is not operable through the driving portion 48 of the outer handle 46 of the outer operator 18. The sliding plate 78 has a first end 120, a second end 122, and an inner region 124 located between the first end 120 and the second end 122. A pair of upper cam arm coupling elements 128a, 128b is located at the first end 120 of the slide plate 78. A pair of lower cam arm coupling elements 130a, 130b is located at the second end 122 of the cam plate. Slip 78.

The spring retention housing 134b includes an elongated cavity 136b defined by a spring retaining wall 138b, and has a spring engaging surface 140b. During the assembly of the connected chassis 14, the sliding plate 78 is placed between the guide channels 90a, 90b of the mounting plate 72, so that the guide rails 132a, 132b are in respective sliding engagement with the guide channels. guide 90a, 90b. Referring to Figures 1, 3a and 4, the elongated cavity 136a defined by the spring retaining wall 138a of the skid plate 78 cooperates with the mounting plate 72 to define an elongate spring retention chamber 144a that provides restraint lateral and lateral support of the compression spring 80a, for example, in the plane of the directions X and Z. The compression spring 80a is placed in the elongate spring retention chamber 144a, and the longitudinal ends of the compression spring 80a are placed between the spring coupling element 92a of the mounting plate 72 and spring engagement surface 140a of the spring retaining housing 134a of the slide plate 78, which thus provide longitudinal retention of the compression spring 80a, by example, in the Y direction. As shown in FIGS. 3A-3D, the longitudinal range of the compression spring 80a is encompassed by the elongate spring retention 144a, although a portion of the spring retention housing 134a is shown fragmented to show the containment of spring 80a. In addition, the elongated cavity 136b defined by the spring retaining wall 138b of the slide plate 78 cooperates with the mounting plate 72 to define an elongate spring retention chamber 144b that provides lateral containment and lateral support of the compression spring 80b , for example, in the plane of the directions X and Z.

As shown in FIGS. 3A-3D, the longitudinal range of the compression spring 80b is encompassed by the elongate spring retention chamber 144b, although a portion of spring tension housing 134b is shown separately to show the contents of spring 80b. Figure 3A is a front view of interconnected chassis 14 with each of the slide plate 78 and the lower cam arm 76 in a rest position, with the upper cam arm I74, and correspondingly with the return piece 64, in an unlocked position. The unlocked position corresponds to the position in which the dead pin of the dead pin assembly 20 (see Figure 1) is retracted. With this arrangement, each of the compression springs 80a, 80b deflects downwardly the coupling elements of the cam arm 130a, 130b of the slide plate 78 in engagement with the cam surfaces 105a, 105b of the lower cam arm 76. , thus defining the respective rest positions of the lower cam arm 76 and the slide plate 78, when no rotational force is applied to the inner operator 66 (see also figure 1). Figure 3B is a front view of the interconnected chassis 14 with the upper cam arm 74 in a locked position, which occurs, for example, when the return piece 64 or the drive element 58 of the lock assembly of the dead pin 19 rotates approximately 90 degrees. The locked position corresponds to a position in which the dead pin of the dead pin assembly 20 (see Figure 1) is extended to engage the knock of the door structure (not shown). With this arrangement, each of the compression springs 80a, 80b continues to deflect the coupling elements of the lower cam arm 130a, 130b from the slide plates 78 in engagement with the cam surfaces 105a, 105b of the lower cam arm 76. Figure 3C is a front view of the interconnected chassis 14, in which rotation of the lower cam arm 76 causes the slide plate 78 to engage and rotate the upper cam arm 74 from the locked position (see Figure 3B) ) to the unlocked position (see figure 3A). More specifically, also referring to Figure 1, a rotation in the counterclockwise direction of the inner operator 66 around the axis of rotation Z2 results in a corresponding rotation of the lower cam arm 76, which in turn causes the vertical displacement of the slide plate 78 in the Y direction, with the cam lobe 104 of the lower cam arm 76 lifting the slide plate 78 while continuing with the cam surface engagement 105a with the cam link coupling element lower 130a of the sliding plate 78. In turn, the coupling element of the upper cam arm 128b engages with cam lobe 94 of the upper cam arm 74, resulting in the rotation of the upper cam arm 74 around the axis of rotation Z1. Likewise, a clockwise rotation of the lower operator 66 around the axis of rotation Z2 results in a corresponding rotation of the lower cam arm 76, which in turn causes the vertical displacement of the sliding plate. 78 in the Y direction, with the cam lobe 104 of the lower cam arm 76 lifting the slide plate 78 with the continuation of the engagement of the cam surface 105b with the coupling member of the lower cam arm 130b of the cam plate. Slip 78. Turn, the coupling element of the upper cam arm 128b engages with the cam lobe 94 of the upper cam arm 74, resulting in an upper cam arm rotation 74 about the axis of rotation Z1. Figure 3D is a front view of the interconnected chassis 14 with the slide plate 74 having the upper cam arm 74 rotated in the unlocked position, as a continuation of the operation described above with respect to Figure 3C. The unlocked position of Figure 3D is achieved from the locked position of Figure 3B when the lower cam arm 76 has rotated at about 45 degrees, by means of the corresponding drive rotation of the inner operator 66.

When the rotational force of the inferred operator 66 is removed, each of the slide plate 78 and the lower cam arm 76 return to the rest position shown in Figure 3A, and the upper cam arm 74 and the corresponding return piece 64, remain in the unlocked position. Although this invention has been described with respect to one embodiment, the present invention may also be modified within the spirit and scope of this description. Therefore, this application is intended to cover any variation, use or adaptation of the invention using its general principles. Also, this application intends to cover said deviations from the present description as long as they are within the practice known or accustomed in the art to which this invention pertains and which are within the limits of the following claims.
