A. Field of the Invention
This relates to loading docks or freight loading docks in which cargo or material must be transported from a truck or trailer to a warehouse or other facility. This device will protect the dock area as well as protect the trailer from unnecessary and unneeded damage during the unloading process.
B. Prior Art
There are other references to loading docks with adjustable bumpers. An example of the prior art can be found at Von Bose U.S. Pat. No. 3,933,111. Another example of an adjustable safety bumper is Ledford, U.S. Pat. No. 6,764,116. This is an adjustable safety bumper.
The device which is described in the current application protects the dock area by employing a bumper system on a loading dock. None of the bumpers in the prior art are similar to the structure that is in use for this particular application.
Bumpers by their very nature are designed to absorb impact. This is to prevent damage to a particular area or a particular item and are commonly used to protect the item from damage.
The current application is attached to the top of the loading dock in a warehouse. In operation the device remains flashing with the loading dock. The bumper area would extend outward from the front of the dock a predetermined distance. A series of holes for the bumper material would be used to attach the bumper material.
The device will be hinged so that the bumper can be rotated approximately two hundred and seventy degrees, if desired.
A series of plates provide strength to the sides as well as the top of the device. Additionally, on the top surface pipes are welded to a vertical hinge plate, which provides additional strength.
It is an object of this device to have an item, which will protect the area of a loading dock but also be allowed to rotate to expose the dock area, if desired.
This device 5 will be installed on the front 12 of a loading dock 12. It will rest so that a pre-determined area of the device will rest on the front of the dock 12 and extend outward from the loading dock.
It will extend a pre-determined distance from the dock 12 and have a pre-determined shape. The first end will be comprised of a vertical hinge plate 21 and a loading dock plate 10 which are secured to the loading dock 12 and a second end, which has a bumper surface 35 that will extend outward from the loading dock. A loading dock plate 10 also is employed to secure the device to the top of the loading dock.
The bumper surface 35 will be mounted to a front plate 30 through a series of mounting holes 40 for the bumper 35 on the front plate 30. It is anticipated that the means of attachment for the bumper 35 will be a bolt 42 and nut 43 combination.
A hinge 20 with a hinge pin 25 will be positioned on the first end of the device, which is secured to the front of the loading dock 12.
The vertical hinge plate 21 is welded to the front of the dock 12 and the use of the hinge 20 and hinge pin 25 will allow the device to rotate upwards as depicted in
On the top surface will be the horizontal hinge plate 15, which is inserted underneath and secured to a top closure plate 32 and the respective side plates 27. The front plate 30 is formed as part of the top closure plate 32. FIGS. 3,7 The top closure plate 32 will most likely be attached to the horizontal hinge plate 15 and side plates 27 by welding. In the middle of the device will be a middle gusset plate 26. The middle gusset plate 26 is necessary in order to provide strength to the device and will probably be secured to the underside of the top closure 32 plate by welding. Side plates 27 are installed to form the structure of the device.
It is anticipated that because this device is in a freight loading or docking system that it will subjected to extreme loads and strength considerations are paramount. The choice of material for the plates and hinge mechanism is likely to be steel.
