Description

[Detailed Description of the Invention] The present invention relates to a brake pedal tread structure for a power carrier.

Conventionally, power transport vehicles have two brake pedals on the left and right.
By separately interlocking and interlocking the left and right running wheels, the left and right running wheels are configured to be able to apply the brakes individually.Furthermore, the left and right brake pedals are placed close to each other, and the left and right brake pedals are connected to each other. It was possible to apply the brakes to both the left and right running wheels by pressing the treadle at the same time, but it was difficult to apply equal force to the left and right treadles, and if the pedals were pressed unevenly, When the transport vehicle stopped, it caused shaking, which was dangerous.

In the present invention, in the left and right brake pedals that are installed in parallel adjacent to the driver's seat of a power transport vehicle, an independent stepping surface is formed on the upper surface of the inclined left and right tread plates of the left and right brake pedals, and the left and right tread plates are A left lower half and a right upper half which are narrower than the tread are formed on the upper and lower edges of each side end adjacent to each other; are disposed flush with each other and staggered in the vertical direction to form simultaneous stepping surfaces on the lower left half and right upper half, and the simultaneous stepping surfaces are recessed to allow simultaneous stepping. The present invention provides a brake pedal tread structure for a power transport vehicle, characterized in that a step is provided between a surface and a single depression surface.

The embodiment of the present invention will be explained in detail based on the drawings.
indicates a power transport vehicle, and transport vehicle A has vehicle body 1.
It consists of a dump type loading platform 3 connected to the rear of the vehicle body 1 via a coupling device 2, and the vehicle body 1 has a driver's seat section 5 on the right side of the fuselage frame 4, and a prime mover section 6 on the rear left side. A front running wheel 7 is arranged below the body frame 4, and a large number of running wheels 9 are arranged below the cargo platform 3 via a chain case 8.

The right half of the fuselage frame 4 is bent and inclined forward and downward from a position above the front running wheel 7, and is bent horizontally from the front end position of the front running wheel 7, thereby providing front and rear horizontal surfaces 10 and 11. A driver's seat 12 is arranged in the center of the rear horizontal surface 11, a handle 14 is rotatably protruded from the center of the front horizontal surface 10 via a dash board 13, and a Two vertical long holes 15, 16
, and left and right brake pedals 17 and 18 project through the elongated holes 15 and 16.

The left and right brake pedals 17, 18 each consist of arm portions 19, 20 and footboards 21, 22, and the base ends of the arm portions 19, 20 are rotatably pivoted to tie rods provided below the fuselage frame 4. The arm portions 19, 20 are curved upwardly in the front from the pivot portion, and tread plates 21, 22 are connected to the upper end thereof in a slanted state upwardly in the front. When the arm parts 19, 20 are rotated forward against the bias of the springs provided at the base ends of each, the intermediate parts of the arm parts 19, 20 slide in the elongated holes 15, 16. The arm part 1 is configured to be used for brake operation, and when the brake operation is released, the arm part 1
9 and 20 are the same long holes 15 and 20 due to the bias of the spring.
In order to maintain the original state by rotating backward while sliding in the brake pedals 16, the present invention forms independent depression surfaces on the upper surfaces of the inclined left and right footplates 21 and 22 of the left and right brake pedals 17 and 18. ing.

Further, the upper and lower edges of the mutually adjacent side ends of the left and right footboards 21 and 22 are provided with a left side lower half 24-1 and a right side upper half 2 which are narrower than the footboards.
5-1, and the left lower half 24-1 and the right upper half 25-1 are arranged flush and staggered in the vertical direction, and the left lower half 24-1
1 and the upper right half 25-1, there is a simultaneous stepping surface 27.
is formed.

Furthermore, the simultaneous stepping surface 27 is recessed to provide a step between the simultaneous stepping surface 27 and the single stepping surface.

This example will be explained in detail below.

The left footboard 21 is made up of a left half 23 and a right half 24 of an oblong plate serving as a single stepping surface.The right half 24 is bent forward into an L-shaped planar shape, and the upper right half is bent forward. Lower right half 24 with a rectangular cutout
-1, and the right footboard 22 is composed of a left half 25 and a right half 26 of an oblong board serving as an independent stepping surface, and the left half 25 is folded forward into an L-shaped planar shape. At the same time, the left lower half is cut into a rectangular shape to form a left upper half 25-1, and the left upper half 25-1 and the right lower half 24-1 are arranged on the same plane. Simultaneously step on the top and bottom surfaces 2
7, and a recessed space 28 is formed on the driver's seat 12 side by the right half 24 and the left half 25.

In addition, the simultaneous stepping surface 27 is the operator's foot B.
The arm part 1 is formed in the center of the right side of the left half part 23 located on the left side.
The upper end of the arm part 20 is connected to the upper end of the arm part 9, and the upper end of the arm part 20 is connected to the left center of the right half part 26 located on the right side, and when the simultaneous stepping surface 27 is activated, the left and right brakes are configured to work together. This is what we are doing.

The embodiment of the present invention is constructed as described above, and when steering the moving power carrier A, the operator, seated in the driver's seat 12, operates the steering wheel 14. The same operation is performed, and when performing turning steering, for example, when turning to the right, the right brake pedal 18 is used.
The brake is actuated by depressing through the right half of the treadle 26, and at the same time, the handlebar 14 is rotated to the right. Conversely, when turning the handle 14 to the left, the left brake pedal 17 is depressed through the left half of the treadle. Part 2
5 and turn the handle 14 to the left.
When stopping the foot, place the upper half of the sole of the foot B in the central recessed space 28, and simultaneously step on the surface 27.
When you step on the same side 27, the left brake pedal 17
Since the lower right half part 24-1 connected to the right brake pedal 18 and the upper left half part 25-1 connected to the right brake pedal 18 are located on the same plane, the left and right brake pedals 17 and 18 Brakes can be applied by applying uniform force,
Therefore, it is possible to perform a smooth stopping operation.

According to the present invention, the tread plates of the left and right brake pedals are bent to provide a simultaneous depression surface forming a recessed space in the center, so that the operator can position the upper half of the sole in the recessed space. By simultaneously depressing the depressing surfaces, the left and right brake pedals can be applied equally, and the same operation can be performed quickly and reliably.
