    • The invention relates to a hand pliers for assembly purposes, more particularly for the assembly of pipe connections at pipe systems, the pliers comprised of two limbs which are rotatably connected to one another via a first link joint (1) and which by means of this link joint (1) are divided into an assembly limb and a handle limb (2,3), wherein the first handle limb (3) is divided into an off-handle lever (14) and into a handle-near lever (15) and wherein these two levers (14, 15) are rotatably connected to one another by means of a bolt (16) via a second link joint, wherein a tension wheel (17) and a ratchet wheel (18) with external toothing (27) connected torsionally proof to it are pivotably arranged on the bolt side by side (16) in axial direction, and wherein the tension wheel (17) engages into a tension means (20) that connects both handle limbs (2,3) to one another, and wherein a spring-loaded dog ratchet (25) is arranged at the handle-near lever (15), the dog ratchet engaging into the ratchet wheel (18) in such a manner that when the handle-near lever (15) makes a latching movement the ratchet wheel (18) and the tension wheel (17) execute a rotation that causes the closing of the pliers, with a spring-loaded arrest ratchet (30) being provided for which also engages in the ratchet wheel (18) and permits a rotation of the ratchet wheel (18) on closing the pliers, but which prevents its rotation in the opposite direction. It is the object of the present invention to provide a hand pliers whose arrest ratchet can be released even if subjected to great assembly forces. To solve this task the invention proposes a switch (33) by the actuation of which the direction of the spring loading of the arrest ratchet (30) is reversible in such a manner that the actuation of the switch (33) takes the effect that the engagement of the arrest ratchet (30) into the ratchet wheel (18) is abolished.

    • The headlight apparatus has at least one headlight unit which includes several headlight subunits (20;40;60; 61;70;90). A base low beam which illuminates a base region in front of the vehicle is produced by at least one of the headlight subunits (20;40) in such a way as to fulfill the basic minimum requirements for a low beam. Additional headlight subunits (60;61;70;90) are connectable to the headlight subunit (20;40) producing the base low beam. At least one of the headlight subunits (20;70) is constructed according to the projection principle and has a reflector, a light source and, following the reflector, a lens and a diaphragm. At least one of the headlight subunits (40;60;61) is constructed according to a reflection principle and has a reflector, a light source and, if necessary, a light permeable disk with optical elements in it. A concentrated or focused light beam is produced by the headlight unit or units (20;70) constructed according to the projection principle while a horizontally scattered light beam is provided by the headlight subunit or subunits constructed according to the reflection principle.
    • 头灯装置具有至少一个头灯单元,其包括若干头灯子单元(20; 40; 60; 61; 70; 90)。 由前照灯子单元(20; 40)中的至少一个产生照明车辆前方的基部区域的基底近光灯,以满足对近光束的基本最小要求。 附加的前灯子单元(60; 61; 70; 90)可连接到产生基极的低光束的头灯子单元(20; 40)。 根据投影原理构造头灯子单元(20; 70)中的至少一个,并且具有反射器,光源以及跟随反射器的透镜和隔膜。 根据反射原理构造头灯子单元(40; 60; 61)中的至少一个,并且具有反射器,光源和必要时具有光学元件的透光盘。 根据投影原理构造的大灯单元或单元(20; 70)产生集中或聚焦的光束,而由前照灯子单元或根据反射原理构造的子单元提供水平散射光束。

    • The headlight has a reflector (10) and a light source (12) which is arranged in a lamp carrier (22), which can be pivoted in relation to the reflector (10) about a horizontal axis (30) between a position for low beam and a position for high beam by means of an actuator (42). Starting from the position for low beam, the light source (12) is moved as a result of the pivoting movement about the axis (30), together with the lamp carrier (22), both in the direction of the optical axis (11) of the reflector (10) towards its vertex and also vertically downward in relation to the optical axis (11). Starting from the low beam reflected by the reflector (10) in the case of the arrangement of the light source (12) in its low beam position, the result achieved is both a concentration of the light beam reflected by the reflector (10) and an elevation of the light beam, so that an effective high beam is generated by means of which the remote region in front of the vehicle is illuminated with a high illumination intensity.
