Abstract

PURPOSE:To improve the operability of traveling pedals by narrowing the lateral width of a backward pedal and deflecting it to one side as compared with a forward pedal. CONSTITUTION:The lateral width of the backward pedal 3 is narrowed as compared with the forward pedal 2 and the set position of the pedal 3 is deflected to one side. In the case of using the pedals 2, 3 as one pedal system, a driver's tiptoe 21 is put on the upper part of the pedal 2 and the heel is put on the upper part of the pedal 3 so that the pedal system can be operated by the movement of the ankle around a rocking spindle 1. In the case of using the pedals 2, 3 as two pedal systems, the heel 20 is put on a floor 11 and supported because the lateral width of the pedal 3 is narrowed, and when the tiptoe 21 is moved right and left in the up state, the tiptoe 21 is moved to the upper part of the pedal 2 or the upper part of the pedal 3, so that forward or backward movement can be accelerated by stepping on the pedal by the tiptoe 21 in each position. Consequently, the generation of operation delay or malfunction can be suppressed.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a traveling pedal for a moving vehicle. This invention allows you to operate the traveling pedal forward or backward by placing your heel on the floor and moving your toes to the forward or backward side of the traveling pedal to operate with only your toes, or by using your entire foot to move the traveling pedal forward or backward. f1 This relates to a device that is placed directly across the forward and reverse sides and is operated using the toes and heels. [Issues to be solved by the prior art and the invention w4] Conventional running pedals can be roughly divided into two types. One has a single pedal that swings back and forth, and the other has two forward and reverse petals in parallel. ^11 The one-piece rear-swinging pedal has all the petals and operating rondos from the petal in one piece, so it is inexpensive, but since the front and back operations are performed only by the movement of the ankle, if you are in a hurry, the operation will be difficult. It had the disadvantage of being prone to delays and operational errors. Also, the one with two forward and reverse pedals in one ML row is highly safe as you only need to step on the desired pedal, but it requires multiple pedals and operating rods from the multiple pedals. This was one of the causes of increased costs, and it was also difficult to repeat the forward and backward movements. [Means for Solving the Problems] This invention attempts to eliminate such problems with conventional devices, and has taken the following technical measures.
That is, in the front-rear driving type traveling pedal 4, which has a forward pedal 2 that accelerates forward by stepping forward and a reverse pedal 3 that increases backward speed by pressing the pedal to the rear, centering on the swing axis 1, the forward pedal 2, backward petal 3
The configuration of the traveling petal for a moving vehicle is characterized by a narrow width and an offset to one side. [Effects of the Invention] With the above-described configuration, the present invention provides the following technical effects. In other words, when using it as a single beta type, you can place your toes on the top of the forward pedal 2, place the base on the top of the reverse pedal 3, use the swing shaft 1 as the center of swing, and operate it by moving your ankle. When using the two-bevel type, the width of the backward pedal 3 is narrower than that of the forward pedal 2, so the heel is supported on the floor and the toe is raised using the heel as a fulcrum. When you swing left and right while the pedal is in the position, the toe will go either above the forward pedal 2 or towards -t; of the reverse pedal 3, so by pressing the toe in that position, you can increase the speed. [Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the component parts described in this example are intended to limit the scope of this invention to only those, unless otherwise specified. Rather, it is just an illustrative example.

The illustrated example shows an HST device 1rt5, which is a static pressure continuously variable transmission device, as the main transmission device of a moving vehicle 6 such as a tractor, and a front-rear rocking traveling pedal 4 that operates the HST device 5. This invention is incorporated into the above.

By swinging the trunnion shaft 7 shown in Fig. 2 back and forth, the IIST'JA device 5 can rotate the same rotation direction of the output shaft (not shown) in forward and reverse directions, as well as increase and decelerate the output shaft. This is what we do.

The running pedal 4 is an integral unit consisting of a wide forward pedal 2 provided at the front and a narrow reverse pedal 3 that projects rearward from the rear end of the forward pedal 2. A swing axis l is provided, and the pedals 2 and 3, which move forward and backward around this swing axis l, are operated by foot in the direction of the arrows ``A'' and ``Open''. Reference numeral 8 denotes a swinging arm, which integrally projects downward from the traveling petal 4. The lower end of this swinging arm 8 and a passive arm 9, which integrally projects from the trunnion shaft 7, are connected to each other. The lower end portion is interlocked and connected by an interlocking rod 10.

It is mounted and supported on top of 1. The mobile vehicle 6 shown in the figure has front and rear wheels 13 and 14 at the front and rear four corners of the body, and a drive shaft 15 of the rear wheel 14.

With respect to J, the reverse pedal 3 is deviated to the right by a dimension rBJ. Using this dimension rBJ, place the heel 20 of the foot on the floor 11-hi near the rear of this rBJ and point the toe 2l along the imaginary line "
When moving to the "C" or "2" state, simply stepping on the tip of the toe 21 moves the front and back pedals 2 and 3 as shown by the arrows in FIG.
The passive arm 9, which is integrated with the trunnion shaft 7, can be operated in the "A" or "A" direction via the interlocking rod 10.
