Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating pedal for operating brakes, clutches, etc. in various machines and devices including construction machines.

This type of operation pedal generally has the following features, as shown in FIG.
It consists of a tread force transmission means consisting of a tread 1, an L-shaped lever 2, etc., and is attached to one end of the lever 2 with a pin 3, and a split pin or an E-ring is attached to both ends of the pin 30 to form a tread. 1 is constructed to prevent it from coming off from the lever 2. By moving the above-mentioned treadle 1 in the direction of the arrow, the pedal force transmitting means using the lever 2 are actuated as shown by the arrows, and actuated parts (not shown) such as brakes and clutches are operated.

The operability of such an operating pedal is greatly influenced by the position of the tread plate 1, the arrangement interval of the tread plate 1, etc.

However, in the conventional operation pedal, a pair of mounting plate parts 4, 4 are provided on the back surface 5 of the footboard 1 with an interval that allows a part of the lever 2 to be inserted into the pair of mounting plate parts 4, 4. Since there are nine bottle through holes, the lever 2 of the treadle 1
There is only one fixed mounting position. For this reason, if it is necessary to increase or decrease the number of operating pedals in the same machine or device due to a change in the target work of the machine or device, the position of the treadle 1 or the interval between the treadles 1 may be changed and adjusted. As a result, nine problems arise in which the operability of the operating pedal is adversely affected.

For example, when it is necessary to add one new set of operating pedals to the two existing sets of operating pedals shown in Figure 1,
As illustrated in Fig. 2, if there is a margin between the two sets of existing operation pedals (shown by solid lines), there is a certain amount of space between the two sets of existing operation pedals (indicated by the solid line). ) can be newly established. Further, as illustrated in FIG. 3, if there is not enough space between the two sets of existing operating pedals, it will be placed outside (on the right side in FIG. 3) of the two sets of existing operating pedals. However, since the conventional operation pedal company, nail JP Sho S8-51323 (2) mounting position of the footboard 1 to the lever 2 is fixed, it is necessary to add a new operation pedal to the two existing operation pedal sets as described above. If these five footboards 1 are added, it is not possible to adjust the mounting positions and intervals of the five treadboards 1, and therefore, the operability cannot be improved, and conversely, the Wj problem has a negative effect on the operability.

In view of the above-mentioned points, the present invention aims to provide an operating pedal that can adjust the mounting position and interval of the footboard.

In the present invention, at least three or more mounting portions for connecting the pedal force transmitting means and the bottle are arranged in parallel on the treadboard at appropriate intervals, and one pin through hole is formed in each of the three or more mounting portions on the same axis.
A set or two or more sets are opened, and the mounting position of the tread to the tread force transmission means is configured to be variable in the direction in which the mounting parts are arranged side by side, or in the direction in which the mounting parts are arranged side by side and in the direction in which two or more sets of pin through holes are opened. It is characterized by what it did.
