Signal pillar
First Claim
Patent Images
1. A signal pillar comprising:
- a plurality of signal elements (2, 2'"'"') which are essentially identical in design and which have connection means (13, 13'"'"') for connecting the signal elements (2, 2'"'"') one on top of the other,wherein each signal element (2, 2'"'"') includes an optical or audible signal transmitter (9), a hollow component (6) for holding the signal transmitter (9), and electrical connecting elements (12) which serve to supply the signal elements (2, 2'"'"') with power individually, andwherein the electrical connecting elements (12) are constructed as wires which each have a generally U-shaped connecting bridge (27) at a first end and a bent connecting leg (31) at a second end, the connecting bridge (27) of one of the signal elements interacting with the connecting leg (31) of an adjacent signal element in a frictional and resiliently sprung fashion when two adjacent signal elements (2, 2'"'"') are connected.

Abstract
A signal pillar includes a plurality of signal elements (2, 2'"'"') which are identical in their design and are arranged one on top of the other. In order to achieve simple and effective mechanical and electrical connection, a bayonet closure arrangement (13) is provided between the signal elements (2, 2'"'"') and an electrical connection base (3), and connection between respectively adjacent components are made by connecting wires having L-shaped legs (31) and U-shaped connecting bridges (27).

17. A signal pillar, comprising:
-
a plurality of signal elements (2, 2'"'"') which are essentially identical in design and which have connection means (13, 13'"'"') for connecting the signal elements (2, 2'"'"') one on top of the other as a result of relative rotation through an angle α
1,wherein each signal element (2, 2'"'"') includes an optical or audible signal transmitter (9), a hollow component (6) for holding the signal transmitter (9), and electrical connecting elements (12) which serve to supply the signal elements (2, 2'"'"') with power individually, wherein the electrical connecting elements (12) are constructed as wires which each have a generally U-shaped connecting bridge (27) at a first end and a bent connecting leg (31) at a second end, the connecting bridge (27) of one of the signal elements interacting with the connecting leg (31) of an adjacent signal element in a frictional and resiliently sprung manner when two adjacent signal elements (2, 2'"'"') are connected, wherein the U-shaped connecting bridge (27) has a pair of outer legs (29,
26), andwherein, when relative rotation through the angle α
1 is being carried out during connection of adjacent signal elements (2, 2'"'"'), the U-shaped connecting bridge (27) comes to rest with both its outer legs against the connecting leg (31) in a frictional fashion. - View Dependent Claims (18, 19)

20. A signal pillar, comprising:
-
a first signal element which includes a first hollow housing having upper and lower ends, a first lamp mounted in the first housing, a plurality of first electrical connecting elements, the first electrical connecting elements having upper and lower end portions, and means for connecting the first lamp to at least some of the first electrical connecting elements; and a second signal element which includes a second hollow housing having upper and lower ends, a second lamp mounted in the second housing, a plurality of second electrical connecting elements, the second electrical connection elements having upper and lower end portions, and means for connecting the second lamp to at least some of the second electrical connecting elements, wherein the upper end of the first housing and the lower end of the second housing having means for connecting the housings when they are rotated relative to one another from an initial position to a final position, the upper end portions of the first electrical connecting elements and the lower end portions of the second electrical connecting elements being moved relative to one another during rotation of the housings and being pressed against one another when the housings are in their final position. - View Dependent Claims (21, 22, 23, 24)
