Abstract

To facilitate climbing into and out of a truck cabin it is known to arrange various kinds of foldable or retractable steps below a cabin door. Thereby the steps can be more or less mutually displaced from the vertical in a staircase-like manner so that the driver may climb the steps with less strain to the arms. However, as the adjacent front wheel of a truck occupies space below the rear portion of the door, the steps have to be located quite near the front of the cabin, so that the forwardly hinged open door will be an obstruction to the driver’s way up to the cabin, forcing the driver to lean backward and hold on to the cabin by the arms in order not to lose balance. According to the invention, means are provided for moving the retractable step not only laterally but also lengthwise to the cabin. Thereby, when the cabin door is open, the step may occupy also the space laterally outside the adjacent front wheel of the truck. The driver is then with small effort able to climb up into the cabin without interfering with the open cabin door.

Retractable step for a vehicle

To facilitate climbing into and out of a truck cabin it is known to arrange various kinds of foldable or retractable steps below a cabin door. Thereby the steps can be more or less mutually displaced from the vertical in a staircase-like manner so that the driver/passenger may climb the steps with less strain to the arms. However, as the adjacent front wheel of a truck occupies space below the rear portion of the door, the steps have to be located quite near the front of the cabin, so that the forwardly hinged open door will be an obstruction to the driver’s way up to the cabin, forcing the driver to lean backward and hold on to the cabin by the arms in order not to lose balance.

An object of the invention is therefore to provide a retractable step that will allow the driver to climb more effortlessly into and out of the cabin. According to the invention, means are provided for moving the retractable step not only laterally but also lengthwise to the cabin. Thereby, when the cabin door is open, the step may occupy also the space laterally outside the adjacent front wheel of the truck. The driver is then with small effort able to climb up into the cabin without interfering with the open cabin door.

 

FIG.1 is a cutaway view from above of a truck cabin 30 provided with a retractable step 10 according to the invention. In this embodiment, step 10 is connected to the truck body 32 by a pair of links 12, 18. One end 14, 20 of each link 12, 18 is rotatably supported at...
