[Prior art]
2. Description of the Related Art Conventionally, for example, a cart or a forklift vehicle as a boarding / exiting vehicle is generally used for unloading work or loading work of a truck bed as a transport vehicle. Since the truck bed has a floor height of about 1 m higher than the road surface, a slope having a gentle slope is installed to eliminate the level difference of about 1 m. The carts and forklift trucks run on the slope of the slope, and the floor surface gets on and off the truck bed from the road surface to perform unloading work and loading work.
In addition, when, for example, an automobile as a boarding / exiting vehicle is put on or taken down from a truck bed as a transport vehicle, the truck bed is at a position where the floor height inside the truck bed is about 1 m higher than the road surface. A slope having a gentle slope is installed in order to eliminate a level difference of about 1 m, and for example, an automobile as a boarding / alighting vehicle is put on or off using this slope.
In addition, sick people are not able to get on and off while sitting in a wheelchair, for example, as a boarding vehicle, because there are steps when getting on and off a car as a transport vehicle, for example, while getting off the wheelchair and receiving assistance from an assistant Getting on and off.

In order to be able to get off from now on, the lower surface directly touching the road surface is formed so that there is almost no step by inclining upward and obliquely upward.
[0027]
The front frame 21b of the rear panel 2 that partially overlaps the rear frame 21c of the front panel 2 in an inclined state is formed with concave locking grooves 26 facing each other. By inserting locking members (not shown) into the opposing locking grooves 26, the panels 2 can be moved in the contracting direction due to vibrations of the getting on and off vehicles when the telescopic sliding slope 1 for transport vehicles is used. Stop.
[0028]
An entry / exit part b of the transport vehicle a, for example, in the truck, below the rear end side of the truck bed that lifts and lowers the load, a panel 2 that contracts when the telescopic slide type slope 1 for transport vehicle is not in use is superposed vertically. A storage unit 3 is provided for storing in a state. The storage unit 3 includes a pedestal 31 on which the panel 2 that is vertically stacked is placed, and a plurality of suspension girders 32 that suspend and support the pedestal 31 at the lower part on the rear end side of the truck bed.
[0029]
The elevating device 4 is configured such that the rear end of the last-stage panel 2-6, which is the uppermost end of the telescopic sliding slope 1 for transport vehicles, on the pedestal 31 of the storage unit 3 reaches the height of the access portion b on the upper side of the storage unit 3. This is a device that raises and lowers the rear end of the last panel 2-6 at the height of the entrance / exit part b to the receiving base 31 of the storage part 3 below the entry / exit part b, and comprises an arm 41 and a cylinder device 42. The
[0030]
One end of the arm 41 is connected to the main body of the transport vehicle a above the storage unit 3 so as to be rotatable up and down by a pivot pin 41a, and the tip side thereof is turned up and down by a pivot pin 41b on the side surface of the last panel 2-6. It is connected rotatably. Further, the arm 41 is bent toward the extending direction of the panel 2 at two locations from one end side to the tip end side.
[0031]
The last panel 2-6 is moved up and down by forward and reverse rotation of the arm 41. That is, in the drawing, the arm 41 rotates clockwise around the pivot pin 41a, thereby raising the last panel 2-6 and rotating counterclockwise around the pivot pin 41a. The last panel 2-6 is lowered.
[0032]
The cylinder device 42 is a drive source that rotates the arm 41 forward and backward about the pivot pin 41a by expansion and contraction of the piston 42a, and the arm of the bent portion where the tip of the expandable piston 42a is closer to the pivot pin 41a. 41 is connected to a pin 41b so as to be rotatable up and down. The cylinder device 42 is disposed substantially horizontally above the storage portion 3, and the piston 42 a is disposed so as to expand and contract in the extending direction of the panel 2. The base end side opposite to the piston 42a is connected to the main body of the transport vehicle a by a connecting pin 42c so as to be rotatable up and down.
[0033]
In the cylinder device 42, when the piston 42a extends, the arm 41 rotates clockwise around the pivot pin 41a to raise the last stage panel 2-6, and when the piston 42a contracts, the arm 41 pivots. The last panel 2-6 is lowered by rotating counterclockwise around the pin 41a.
[0034]
Next, the operation based on the configuration of the embodiment of the invention will be described below.
When using the telescopic slide-type slope 1 for a transport vehicle, a method of raising the panels 2 in the storage section 3 to the height of the entrance / exit b of the transport vehicle a and then pulling out and extending the panel 2; There is a method in which the overlapping panels 2 in 3 are pulled out and extended, and then the last panel 2-6 is raised to the height of the entrance / exit b of the transport vehicle a.
[0035]
In the case of the method of raising each panel 2 which overlaps initially, the raising / lowering apparatus 4 is operated and the piston 42a of the cylinder apparatus 42 which is shrink | contracted is expanded. The extending piston 42a presses the arm 41, the tip of which is pin-connected, in the extending direction of the panel 2. The pressed arm 41 rotates clockwise around the pivot pin 41a. The last stage panel 2-6 at the lowest position of each overlapping panel 2 is connected to the tip of the arm 41 that rotates clockwise, and the tip of the arm 41 is moved to the lower position when the arm 41 rotates clockwise. Ascend to the upper position.
[0036]
The overlapping panels 2 are connected to the tip of the ascending arm 41 via the last panel 2-6, whereby the overlapping panels 2 are raised to the height of the entrance / exit b of the transport vehicle a. And if the last panel 2-6 of the lowest position of each panel 2 to pile up raises to the height of the entrance / exit part b of the transport vehicle a, expansion | extension of the piston 42a of the cylinder apparatus 42 will be stopped.
[0037]
After the elevating device 4 stops, when the foremost panel 2-1 at the uppermost position of each overlapping panel 2 is pulled out, the foremost panel 2-1 moves forward diagonally forward due to its own weight, and then the foremost panel 2- The next panel 2-2 following 1 is pulled out, and then pulled out by the same operation one after another. When the panel 2-5 is pulled out from the last panel 2-6 and reaches the maximum extension state, the first panel The tip of 2-1 contacts the road surface.
[0038]
During the operation of pulling out each panel 2, the panels 2 that are in a contracted state overlap with each other, and the engagement pins 24 inserted and engaged in the left and right slide guides 23 are relatively extended while being guided in the slide guides 23. In order to move in the direction, each panel 2 is withdrawn to Sooms. When the engaging pin 24 reaches the end in the extension direction, the end becomes a stopper, so that the panel 2 comes to the maximum extension state without coming off by coming into contact with and stopping.
[0039]
When each panel 2 is pulled out, the column 25 housed in each panel 2 is rotated downward about the connecting pin 25a at the upper end by removing a locking pin (not shown) that stops this, The lower end of the support column 25 is grounded on the road surface and supports the slope 1 that is in the most extended state.
[0040]
On the other hand, in the case of the method of pulling out the panel 2 first, when the foremost panel 2-1 at the uppermost position of the overlapping panels 2 in the storage unit 3 is pulled out, the foremost panel 2-1 has its own weight. As a result, the next panel 2-2 following the front panel 2-1 is pulled out, and the next panel 2-2 is pulled out one after another by the same operation, and the panel 2 from the last panel 2-6 is pulled out. When −5 is pulled out and is in the most extended state, the tip of the foremost panel 2-1 contacts the road surface.
[0041]
During the operation of pulling out each panel 2, the panels 2 that are in a contracted state overlap with each other, and the engagement pins 24 inserted and engaged in the left and right slide guides 23 are relatively extended while being guided in the slide guides 23. In order to move in the direction, each panel 2 is withdrawn to Sooms. When the engaging pin 24 reaches the end in the extension direction, the end becomes a stopper, so that the panel 2 comes to the maximum extension state without coming off by coming into contact with and stopping.
[0042]
When each panel 2 is pulled out, the column 25 accommodated in each panel 2 is rotated downward about the connecting pin 25a at the upper end by removing a locking pin (not shown) that has stopped this, Although the lower end of the support column 25 is in contact with the road surface, since the slope 1 in the most extended state does not reach a predetermined inclination height, the lower end of each support column 25 contacts the road surface in an inclined state.
[0043]
After each panel 2 is pulled out and reaches its maximum extension state, the lifting device 4 is operated to extend the piston 42a of the contracting cylinder device 42. The extending piston 42a presses the arm 41, the tip of which is pin-connected, in the extending direction of the panel 2. The pressed arm 41 rotates clockwise around the pivot pin 41a. The last stage panel 2-6 at the uppermost end position in the most extended state is connected to the tip end of the arm 41 that rotates clockwise, and when the arm 41 rotates clockwise, the tip end of the arm 41 is moved from the lower position. Ascend to the upper position.
[0044]
Thereby, the last stage panel 2-6 of the uppermost end position of the most extended state raises to the height of the entrance / exit part b of the transport vehicle a. If it raises to the height of the entrance / exit part b, expansion | extension of the piston 42a of the cylinder apparatus 42 will be stopped. Further, when the last panel 2-6 at the uppermost end position in the most extended state rises to the height of the entrance / exit b of the transport vehicle a, each tilted column 25 is in a vertical state and its lower end is grounded to the road surface. Supports slope 1.
[0045]
In this way, each panel 2 stored in the storage section 3 on the lower side of the entrance / exit part b of the transport vehicle a is pulled out, and a predetermined gentle gap is provided between the entrance / exit part b of the transport vehicle a and the road surface. A slope 1 having a slope is formed. For example, a forklift truck as an getting-on / off vehicle travels on the slope 1 and uses the slope 1 to unload the cargo from, for example, a truck bed as the transport vehicle a, or to load the truck on the truck bed.
[0046]
When the most extended slope 1 is stored again in the storage part 3 below the entrance / exit part b of the transport vehicle a, the lifting / lowering device 4 is actuated to reach the last of the entrance / exit part b of the transport vehicle a. Lower the step panel 2-6 to the height of the storage unit 3. Further, each column 25 is rotated upward about the connecting pin 25a at the upper end to be accommodated in the panel 2. Each of the stored struts 25 is stopped by a locking pin (not shown) so as not to come out downward.
[0047]
The elevating device 4 is operated to contract the piston 42a of the extending cylinder device 42. The contracting piston 42a pulls back the arm 41, the tip of which is pin-connected, in the contracting direction of the panel 2. The retracted arm 41 rotates counterclockwise around the pivot pin 41a.
[0048]
The last stage panel 2-6 at the highest end position in the most extended state is connected to the tip of the arm 41 that rotates counterclockwise, and the tip of the arm 41 moves upward as the arm 41 rotates counterclockwise. Lowers from position to lower position. Thereby, the last stage panel 2-6 of the uppermost end position of the most extended state falls to the height of the storage part 3 below the entrance / exit part b of the transport vehicle a. When lowered to the height of the storage unit 3, the contraction of the piston 42a of the cylinder device 42 is stopped.
[0049]
After the lifting device 4 is stopped, the front frame 21b of the foremost panel 2-1 is pressed toward the transport vehicle a. The pressed front panel 2-1 is retracted and accommodated in the adjacent rear panel 2-2, and the front panel 2-1 is superimposed on the panel 2-2. When the foremost panel 2-1 is stored in the rear panel 2-2, the overlapping panel 2-1 and panel 2-2 are retracted and stored in the rear panel 2-3, and the panel 2- The panel 2-1 and the panel 2-2 are superimposed on the 3.
[0050]
Thereafter, the same operation is performed, and after the panels 2-1,... 2-5 are stacked and stored in the last panel 2-6, The panel 2 is stored.
[0051]
