Definitions
- a mechanical latch unit for a main drive unit with a permanently coupled four bar latch mechanism within a housing with a first link with a base end connected with the housing via a first joint and with a top end connected with the first end of a second link via a second joint, with a third joint to connect the second end of the second link with the second end of a third link, whereby the first end of the third link interconnects with a trip unit and a pivot centre of the third link is connected with the housing via a fourth joint, whereby the second joint, the third joint and the fourth joint approximately are lying in one line and whereby the load of the traction link of the main drive unit is applied to the top end of the first link next to the second joint with defined deviation rectangular to this line in direction to the first joint.
- Figure 4 shows in a side view the frontal area of the latch unit
- Figure 5 shows the relevant links and joints of the latch unit
- Figure 6 shows the relevant links and joints of the latch unit in the form of a line drawing.
- Figure 3 shows a three-dimensional view of the latch unit 1. Unlike Figure 2 this Figure 3 shows a closed housing 9 with both housing plates 10 (consisting of sheet metal components 11 , 12). Further the external interface bolts 110, 111 , the end stop bolt 70, the main lever 20 with the axle 26, and the catch main roller 30 are shown as well as a slot 13, the release links 40, 50, the integration block 90, the actuator unit 100 with the actuator coil 101 and the swivel anchor 102.
- Figure 4 shows in a side view the frontal area of the latch unit 1.
- the housing 9 with the housing plates 10, the external interface bolts 110, 111 and the end stop bolt 70 are shown as well as the main lever 20 with the axle 26 and the catch main roller 30, the release links 40, 50 with the joints 35, 45 and the bearing 55 just as the actuator unit 100 with the actuator coil 101 , the swivel anchor 102 and the actuator trip lever 60.
- the contact main roller 30 catches load and distributes it within main lever 20 which is made out of sheet metal layers.
- the main portion of the load is directly transferred into the housing 9 via the main lever 20 (also called catch link) and the main bearing 25.
- an additional load sleeve can be introduced between main lever 20 and main bearing 25.
- the main bearing 25 transfers the load via a standard precision parallel bolt forming the main axles into the housing 9. Throughout the whole linkage chain either roller bearings or friction sleeve bearings can be introduced.
