Ar;laege_«it_motion flashing device

Especially for cyclists and pedestrians, being seen in the dark is extremely important in order to avoid accidents. The situation is particularly dangerous when crossing streets or when turning/merging as a cyclist, as the change of direction is usually not illuminated.

Flashing devices that are permanently mounted on bicycles, for example, are susceptible to interference and require a lot of money and material. Furthermore, the devices are often overlooked because they are not mounted far enough out.

The purpose of the device according to the invention is to eliminate the aforementioned disadvantages.

The modern arm lamp with motion flashing device basically consists of a housing with a reflective light cap. The housing has retaining contours for attaching elastic straps so that the device can be fixed to the arm of a cyclist/pedestrian. The housing contains a light bulb, power supply contact plates and the battery/batteries. The special feature is that in addition to the on/off option, a sliding switch is integrated, which is moved locally by arm movements - as a result of an inclined plane - and closes or opens two switching contacts depending on the arm position. The control of the circuit created by the switch contact connection, i.e. the flashing, can either be done by moving the macaw up and down several times, or a flashing light bulb can be integrated, so that the arm is only raised once and the flashing is then done automatically by the light bulb. The light is switched off by lowering the arm.

Of course, it is also possible for the battery/batteries themselves to be used as a sliding switch. A weight pendulum with a circular movement can also create the switching contact connection. Another advantage is that with this arm lamp, no push button has to be pressed for the switching process, i.e. the user does not need to use his hands for the switching process.

The device is explained with reference to Figures I to III.

Fig. I: Arm lamp with integrated sliding switch Fig.II: Arm lamp with battery as sliding switch Fig.III: Sliding switch control by means of a tilted plane

According to Fig. I, the reflection cap (2) with the incandescent cap (11), the batteries (j) and (4) and the bulb (5) are firmly arranged in the housing (i). The current is guided by the contact spring plates (6), (7) and (8), whereby the contact spring plates (7/8) are simultaneously battery terminal plates. The ends of the contact spring plates (7) and (8) are guided outwards approximately parallel. If the arm is raised by the user (see Fig. III), the sliding switch slide (9) slides downwards due to its own weight and connects the contact spring plates (7/8) - i.e. the bulb lights up. When the arm is lowered - see Fig. III - the sliding switch slide again slides into the starting position due to its own weight. Due to the spring action of the contact springs (7/8), these also return to their initial position, ie the contact is open and the bulb does not light up. By raising and lowering the arm several times, an individual oil-link effect is achieved. The slide switch can also be pushed to permanent contact or off using the locking button (10).

According to Fig.II, the reflection cap (22) and the light bulb (23) are also fixedly arranged in the housing (21).

A flexible contact ( rlk) connects the light bulb (23) to the upper contact on the battery ( ²⁵ ). The ^battery (25) is also a power supply. If the battery is lifted by the user's arm, the battery slides down on its tip and rests against the contact ( ^ü £) with the fingers, which lights up the light bulb. The flashing function works at Fi r, . I be sore. The relay output can also be set to On or Off using the control button (26) .

Claims (1)

Jürgen P. Dambroth MdSCh ₁ Ing. Protection claims Arm lamp with flashing device characterized by the fact that in a housing with battery/batteries and light bulb, in addition to the on/off switch, there is a sliding switch which, due to its own weight, automatically closes or opens a circuit when the arm is moved. Device according to claim 1, characterized in that the battery/batteries is/are sliding switch slides. Device according to claim 1-2, characterized in that a flexible contact element connects the light bulb and a terminal of the battery. Device according to claims 1-3, characterized in that the contact between the light bulb and the battery is made by a compression spring, the spring constant of the compression spring being such that the spring is slightly compressed by the pressure of the battery. Device according to claim 1, characterized in that the flashing effect is produced by a flashing bulb. Device according to claim 1-5, characterized in that the arm lamp is surrounded by a light cap in the area of the light bulb.
