Speed hump device

Abstract

A speed hump device for discouraging vehicles form exceeding a designed threshold speed is disclosed. The speed hump device mainly comprises: a housing device, whose figure is like a box, having a housing room therein and a opening thereon; a hump device with a hump member and a arc-shaped member pivoted on the housing device by a first pivot, the hump member can be rotated in and out the housing room from the opening about the first pivot; a transmission device including a gear set, a transmitting mechanism and a abutment member, wherein the arc-shaped member is engaged with one gear of the gear set; a rebound device used to push the hump member out the housing device when no extra force presses on the hump member. When a car passing through the speed hump device with a slow speed, e.g., below a threshold speed, the abutment member will be put down and the hump member can be depressed in the housing room by the wheels of the car, hence the hump member as a jolt will disappear and the car will traverse smoothly; on the contrary, if the speed of the car is over the threshold speed, the hump member will be still in the position out the housing room that a jolt will occur to cause a impact effect to the car. Additionally, the hump member of the speed hump device will have an impedimental effect to a car goes against the traffic flow direction. Moreover, it does not consume any additional energy to drive the speed hump device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a speed hump device, and more particularly to a speed hump device for discouraging motor vehicles form exceeding a demanded threshold speed. [0003] 2. Description of the Prior Art [0004] One such known traditional speed hump 100, as shown in FIG. 1, is a so-called “sleeping policeman” including one or more raised portions as humps extending across, usually fully across, the “controlled” road or traffic surface. By the sufficient height of the raised portions, the traditional speed hump 100 causes noticeable impact or jolt effect to cars or other motor vehicles. In general, although different traditional speed humps could be designed to any kind of figure and made of different materials, they have all motor vehicles run thereon suffered a uncomfortable impact effect weather the speed of the motor vehicles are fast or slow, and that is real a torment to a diver who obey the traffic rul...

AI Technical Summary

Benefits of technology

[0007] It is one of objectives of the present invention to provide a speed hump device which can improve the disadvantages of the traditional speed hump devices.

[0008] It is another one of objectives of the present invention to provide a speed hump device which can automatically determine weather let a motor vehicle get a smooth road surface or not according to the speed of the motor vehicle passing through thereon.

[0009] It is another one of objectives of the present invention to provide a speed hump device that can be pre-set a demanded threshold speed thereof and if a speed of a motor vehicle passing through thereon is over the demanded threshold speed, the speed hump device will cause an impact effect to the motor vehicle, otherwise, if the speed is below the demanded threshold speed, let the motor vehicle go through smoothly.

[0010] It is another one of objectives of the present invention to provide a speed hump device that has a impact effect to a motor vehicle whose speed is faster than a certain speed and an impedimental effect to a motor vehicle whose going direction against the traffic flow direction, and moreover it does not need to consume any additional energy to drive the speed hump device.

Problems solved by technology

In general, although different traditional speed humps could be designed to any kind of figure and made of different materials, they have all motor vehicles run thereon suffered a uncomfortable impact effect weather the speed of the motor vehicles are fast or slow, and that is real a torment to a diver who obey the traffic rule and drive slowly, specially, slower than a demanded threshold speed, further, that also causes harm to the motor vehicles.

Therefore, the traditional speed hump 100 is not suitable for most traffic roads.

However, the traditional traffic hump 200 could not be used to be a speed hump, as the traditional speed hump 100 shown in FIG. 1, since the sharp figure of the traditional traffic hump 200 will cause serious harm to a running car.

Due to the disadvantages of the traditional speed humps mentioned above, it needs to provide a speed hump device which can automatically determine weather let a motor vehicle get a smooth road surface or not according to its speed.

For example, when the speed of a running car is over a demanded threshold speed, the hump member of the provided speed hump device would be in the position above the road surface and that causes an uncomfortable impact or jolt effect to the running car; and when the speed is below the demanded threshold speed, the hump member will be depressed into alignment with the road surface by the wheels of the running car and the uncomfortable impact or jolt effect will disappear, then the running car traverses the road smoothly.

Besides, the provided speed hump device has an impedimental effect to the motor vehicles whose going direction against the traffic flow direction.
