Embodiment Construction

[0022] Correspondingly, figure 1 A cross-sectional view of a pointing device A for an automobile is shown. Built on a plate 1 , for example as a support element, it also comprises a double pointer drive 2 for driving the two concentrically arranged pointers 4 and 5 . The pointer 5 is designed as a low pointer and is located behind the dial 3 in a plan view looking at the indicating device A. As shown in FIG.

[0023] In order to make the position of the low pointer visible, an illuminating body 11.1 is arranged on the low pointer in such a way that it can move with it. According to the invention, a permanently arranged light guide body 10 . 1 is provided for the input of light 18 generated by a light source 7 designed as a light emitting diode (LED). The input of the light rays 18 generated by the light-emitting diodes 7 takes place at a fixedly arranged light input surface 10 . 10 formed on the light guide body 10 .

[0024] In order to be able to achieve as uniform a lig...

Abstract

The device (A) has a dial-plate (3), and an indicator (5) arranged in a plane, which lies behind the dial-plate. An illuminant (11.1) is arranged at the indicator, and another illuminant (10.1) is provided for transmission of light from a fixed light source (7) such as LED. The illuminant (10.1) is fixedly arranged for supplying light into the illuminant (11.1), and is provided with a fixedly positioned light-coupling surface (10.10). A recess is provided for rotatable mounting of a section comprising the light-coupling surface.

Description

technical field [0001] The invention relates to an indicating device. Background technique [0002] From an unpublished application of the same applicant, an indicating device for motor vehicles is known, which comprises two pointers which are pivotably arranged in different planes, wherein at least one pointer is arranged between the front pointer and the rear pointer A dial such that the rear hands are at least partially covered by the dial, and the indicating device has an illuminating body assigned to the rear hands. The lighting device is a light source that can be switched to an active state, placed on the "lower pointer" and has corresponding conductive leads. Both the expense of providing leads for supplying the light source and the contact when assembling a low-lying pointer are considered disadvantageous. [0003] Furthermore, DE 102 22 503 A1 describes a pointer with a light guide in which a uniform illumination of the indicator disc is provided. The light is f...
