Device for displaying the acceleration of a power vehicle

Behind a power vague ago propelled motorist has been more or Veniger no way to turn off the acceleration of its Kraftvagens with some accuracy to that of driving in front of him Xraftvagens to maintain the required safety distance especially at higher acceleration of the two power vague, overtaking presumably not is intended. This is because the motorist driving behind a motor vehicle cannot, for example, already recognize the reduction in the acceleration of the motor vehicle driving in front of him at the point in time at which the reduction in acceleration occurs, in particular at higher acceleration. This applies in particular to the case in which the reduction in acceleration is abrupt, for example in the case of one equipped with an engine brake. Load power wager, errolgi by actuating the engine brake

On the contrary, he was only aware of the reduction in slowing down _; when the distance between the two vehicles is shortened. Since the shortening of the distance takes place very quickly at higher acceleration, the driver behind the vehicle in front is often forced to brake his vehicle. If he does not recognize the shortening of the distance in time, there is also the risk of colliding with the vehicle driving in front of him. Motorists who drive cautiously manage to reduce the acceleration by pressing the footbrake at short intervals in order to make the following motorist aware of the reduction in acceleration by illuminating the stop lights. Just as the driver behind a motor vehicle cannot recognize the reduction in the acceleration of the vehicle in front at a higher acceleration at the time the reduction in acceleration occurs, so he can often not see the acceleration of the motor vehicle in front of him already at the time of the

Recognize the occurrence of acceleration, ir is thereby not being able to accelerate his car immediately after entering the Acceleration of the motor vehicle driving in front of it to adjust its acceleration if he endeavors to maintain the distance between the two vehicles.

It is the object of the invention to provide an inside or at a suitable location at the rear of a motor vehicle To create an easily attachable device on the outside, which is behind the one equipped with the device Motor vehicle allows driving motorists to both maintain and change the The acceleration of the vehicle driving in front of him can be easily recognized, namely the Change in acceleration at the time the change occurs. The device according to the invention is characterized by an in an end face with an elongated, Window-like cut-out housing, vertically pivotable, made of transparent Material existing, at least frontally curved elongated hollow body, the

brought into equilibrium by a weight is and its curved part on the outside in three extending approximately in the axial direction, differently colored fields is divided.

According to a proposal of the invention, the fields are evenly colored, with the middle field tapers towards one end of the hollow body.

According to another proposal of the invention, the outer fields of the hollow body are to the shaded evenly or stepwise towards the middle field.

In the drawing, the device for displaying the acceleration of a motor vehicle is in one embodiment of the invention. It shows:

The device shown in the drawing consists of a housing 1 made of non-transparent material, which has an elongated, window-like cutout 2. Kit 3 is an elongated hollow body made of transparent material, which is pivotable in the interior of the housing ι about transverse pin 4 with the interposition of ball bearings 5. A weight 6 is arranged in the hollow body 3, by means of which the hollow body 3 is brought back into the equilibrium position. The hollow body Γ is arched and open on the back. The curved part of the hollow body 3 is on the outside divided into three fields 7 _f S, 9 which extend approximately in the axial direction and which are different but uniform, ie colored so that each color of a field is the same throughout. In the exemplary embodiment shown in the drawing, one field is colored yellow, the middle field is colored black and the adjacent field is colored green. That

The middle field tapers towards one end of the hollow body 3. In the housing 1 is furthermore a light source labeled Io is arranged, the rays of which enter the interior of the hollow body 3 fall and lighten this one. The light source Io can come from the battery, for example of the motor vehicle are fed. 11 with a return spring is referred to, which with its one 3nde on the outer wall of the hollow body 3 and at its other end on the inner wall of the housing 1 is attached. The device can be attached to the rear of the vehicle for the driver of the rear attached to the motor vehicle equipped with the device in a clearly visible place will. It can also be inside the vehicle near the rear window, for example on the Storage can be arranged between the rear seat and rear window.

The mode of operation of the device is as follows.

With constant acceleration of the with the invention Device equipped motor vehicle is in the window-like cutout 2 of the housing 1 the device only the black field of the hollow body 3 is visible. The one behind the with

Motorists equipped with the device are able to determine that the acceleration of the motor vehicle in front of them is constant. When the acceleration is reduced, due to the inertia of the weight 6, the hollow body 3 pivots in the counterclockwise direction, whereby the yellow field of the hollow body 3 is visible in the window-like cutout 2 of the housing 1 in addition to the black field, in a size that corresponds to the degree corresponds to the reduction in acceleration (Fig.5). If, on the other hand, the acceleration is increased, the hollow body pivots clockwise so that the green field of the hollow body 3 is visible in the window-like cutout 2 next to the black field, also in a size that corresponds to the degree of magnification of the acceleration. The decrease as well as the increase in the acceleration can of course also assume such a value that the black field in the window-like section 2 is no longer and only the yellow or green field sicVitbd.- ", Inf ^ lcre der Au ^ ¹ " Bl 1 ur, τ ".es

Hollow body 3 through the light source Io is the Change in acceleration even in the dark in the window-like section 2 of the Hollow body 3 clearly visible. If the absolute acceleration is reduced accordingly, it swings the hollow body 3 by the weight 6 with the support of the return spring 11 again : n Direction of the starting position until the latter is reached with constant acceleration.

If necessary, the hollow body 3 can with a damping device are provided to about occurring jerky movements of the hollow body 3 prevented.
