DE9301120U1 - Bollards can be tilted on all sides - Google Patents

Description

The invention relates to a barrier post that can be tilted on all sides and has the features according to the generic term of the main claim.

Bollards of this type are used to block off traffic areas. They consist of a pipe on a foundation anchored to the ground and held in a vertical position. The connection between the pipe and the foundation is such that when a vehicle hits the pipe, i.e. when high forces are generated, it tilts to the side at an angle. This tilting contributes to traffic safety because it uses up forces and reduces the impact.

! The object of the invention is to further equip a barrier post of the type in question with regard to traffic safety.

This problem is solved by a barrier post with the j features according to the main claim. The subclaims contain alternative embodiments of this solution or preferred structural designs thereof.

With such a barrier post, an acoustic or optical signal is triggered at the same time as the inclination, which can be heard in the surrounding area. Since the impact of a vehicle on the post can result in an accident, the signal sounds an alarm so that bystanders are alerted and can provide first aid.

In its simplest design, the post can be a metal tube, which is electrically conductive, with a circular cross-section. In a further design, the tube can also have any cross-section and be made of a different material, such as plastic, if a circular metal bushing is inserted in the area of the pendulum. 10

In the following, embodiments of the invention are described with reference to the accompanying drawings:

Fig. 1 shows a section through the upper part of a barrier post according to the invention in vertical position;

Fig. 2 shows a figure corresponding to Figure I ₁ but with an inclined post;

Fig. 3 is a section through a post of a ^5 variant of Figure 1, where the tube of the

post is vertical;

Fig. 4 shows the pipe according to Figure 3 in an inclined position.

In a barrier post according to the invention, a metal tube 10 stands vertically on a foundation (not shown) anchored to the ground. In the upper area of the metal tube 10, an installation space 12 is separated by a metal plate 11. The installation space accommodates a signal horn 14, a battery 15 suitable for operating the signal horn, an electronic switching element 16 and electrical cables 18 for electrically connecting these parts.

On the bottom of the plate 11, a metal pendulum is suspended centrally, which can swing in all directions, so that the weight of the pendulum can strike the inside of the metal pipe wall when the pipe is inclined, as shown in Figure 2.

The inclination of the pipe occurs when a vehicle has hit the pipe with great force. The connection between the pipe and the foundation allows such an inclined setting. The circuit of the electric lines 18 is arranged in such a way that it is interrupted in the vertical position according to Figure 1, but that it is closed when the pendulum 17 is in the inclined position according to Figure 2.

jQ touches the pipe wall, so that the signal horn 14 receives power and is put into operation. The electronic switching element 16 in the circuit interrupts this again after a set time. The installation room 12 is covered by a roof 13,

■where the roof is spaced away from the pipe wall so that nothing stands in the way of the sound of the signal horn. In the embodiment according to Figures 3 and 4, the installation space in the pipe is completely covered with a cover on which a flashing light 21 is installed.

2Q This flashing light is included in the circuit shown in Figure 1 and and is activated when the post is tilted as shown in Figure 4 when the pendulum strikes.

In a further embodiment of the invention, the connection between the pipe and the foundation is

set so that even a light touch of the pipe causes an inclination and the pendulum hits the pipe wall or an inserted metal sleeve with a smaller diameter, so that OQ is given a signal even with a light touch. In this version, the barrier post can be set up where the driver is to be given an indication when he ^has reached the correct position, for example in a garage or on a fenced-off parking area.
