When the left side accelerator pedal 5 is trodden in, the roller 7 will rotate in contact with the automobile side accelerator peral AP which will be smoothly operated.
The proces of fitting and removing the embodiment apparatus by the above formation to and from an automobile shall be explained in the following. In the solid line state in FIG. 7, the cover member 2 is fitted to the base 1 fitted to the driving seat floor surface of the automobile, that is, the left side accelerator apparatus body is fitted to the automobile. In this case, as in FIGS. 1 and 4, the engaging pins 16 of the cover member 2 are engaged with the left side engaging holes 15 of the base 1 and the engaging pins 20 on the shielding plate fitting bracket 9 side are engaged with the right side engaging holes 14 of the base 1 through the inserting holes 17 of the cover member 2 so that the cover member 2 may be positively fitted and fixed to the base 1. At this time, the engaging pins 20 of the bracket 9 engaged with the right side engaging holes 14 will be energized in the leftward direction by the spring 22 so that the engaging pins 20 may be prevented from being pulled out of the right side engaging holes 14 and the left side accelerator apparatus body (cover member 2) may be prevented from dropping.
On the other hand, in the operation of removing the apparatus body from the automobile side (base 1), as shown in FIGS. 6 and 7, the shielding plate 10 is pulled in the rightward direction so as to be displaced to the two-point chain line position in FIG. 7, the engaging pins 20 of the shielding plate fitting bracket 9 are disengaged from the right side engaging holes 14, further, as in FIG. 8, the apparatus body is lifted on the right side and the engaging pins 16 of the left side cover member 2 are disengaged from the left side engaging holes 15.
In fitting the left side accelerator apparatus body to the automobile, it is fitted in the order reverse to the above mentioned order. That is to say, the shielding plate 10 of the apparatus body is pulled in the rightward direction while the engaging pins 16 of the left side cover member 2 are being engaged with the left side engaging holes 15 of the base 1, the shielding plate 10 of the apparatus body is pulled in the rightward direction, the cover member 2 is fitted to the base 1 as it is and the shielding plate 10 is returned to the original position so that the engaging pins 20 of the bracket 9 may be engaged with the right side engaging holes 14 and the apparatus body may be fitted to the automobile.
In the case of the above fitting, when the right side arm 6 is extended and contracted by adjusting the position of connecting the first arm part 31 and second arm part 32 by using the screws 35 and adjusting slots 34A and 34B so that the roller 7 fitted to the right side arm 6 at the tip may contact the automobile side accelerator pedal, the optimum contact position of the roller 7 and the automobile side accelerator pedal AP will be found and the first and second arm parts 31 and 32 will be screwed and fixed. In case the left side accelerator user sits on the driving seat and treads in the left side accelerator pedal 5 with the left foot, so that the left side accelerator may be in the optimum position in which it is easy to use, the arm 4 fitting position and angle with respect to the main shaft 3 will be adjusted by the holding member 24 at the lower end of the left side pedal arm 4 and the arm 4 will be fixed in the optimum lateral (right and left) direction position and fitting angle by using the screw 25. Further, by selecting either of the pin inserting holes 27A and 27B of the pedal fitting bracket 26 integral with the left side accelerator pedal 5, the bracket 26 will be fitted to the left side pedal arm 4 through a pin to adjust the height.
The general operation of the above mentioned embodiment shall be explained in the following. In case the cover member 2 having the left side accelerator apparatus body is fitted to the base 1 and a person physically handicapped in the right lower limb operates the accelerator by the left side accelerator pedal 5, the left side accelerator pedal 5 fitted to the left side pedal arm 4 at the tip will be made to fall on the floor surface side so that, as shown by the imaginary line in FIG. 3, the right arm side roller 7 may contact the automobile side accelerator pedal AP and the left side accelerator pedal 5 will be trodden in with the left foot so that the main shaft 3 to which the left pedal arm 4 is fixed may rotate, as operatively connected with it, the right side arm 6 secured to the main shaft 3 at the right end may rotate in the same direction as of the left side pedal arm, the roller 7 at the tip of the right side arm 6 may push down and operate the automobile side accelerator pedal AP and, as a result, the automobile will be accelerated the same as in the case that the ordinary accelerator pedal is trodden in. Also, the automobile side accelerator is prevented by the shielding plate 10 from being operated irrespective of the left side accelerator operation by any force (such as the contact with the right foot or the fall of an object.
On the other hand, as in the case that the ordinary driver operates the accelerator with the right foot, in case the left side accelerator is not used, as described above, the left side accelerator apparatus body (cover member 2) will be removed from the automobile (base 1) and the ordinary accelerating operation will be made. This removal can be made by one touch without using a tool.
According to the formation of the above embodiment, there can be obtained a left side accelerator apparatus for physically handicapped persons which can be fitted and removed by one touch operation, in which an automobile accelerating operation can be made with the left foot and which can be removed and can be stored in another place so as not to be in the way of the ordinary accelerating and braking operations when it is not used. The conventional left side accelerator apparatus is different in the fitting position and the dimensions of the respective parts depending on the kind of the fitted automobile and has had to be made for each kind of the automobile. However, in the apparatus shown in the embodiment of the present invention, the fitting position of the base 1 to be fitted to the driving seat floor surface and the position of the roller 7 in contact with the automobile side accelerator pedal can be so easily adjusted that the difference in the shape of the driving seat floor surface and in the position of the already provided accelerator pedal depending on the kind of the automobile can be well coped with without modifying the automobile body and the style when fitted is good. Further, the fitting position and angle of the left side pedal arm 4 and the height of the left side accelerator pedal 5 can be so easily adjusted that the size of the foot of the left side accelerator user and the using position can be freely coped with.
FIG. 9 shows another embodiment of the present invention. In this case, in the fitting part 2A of the cover member 2 fitted to the base 1, and engaging tongue piece 40 as a left side engaging member is integrally formed and, in the shielding plate fitting bracket 9, an engaging tongue piece 41 as a right side engaging member is integrally formed. Recesses (incisions) 42 and 43 in which the engaging tongue pieces 40 and 41 can be respectively freely fitted are formed on the base 1 side. The other formations are the same as of the above described embodiment.
By the way, in the above mentioned respective embodiments, six screw fitting holes are provided in the base 1 but may be changed to be in any position and number in response to the driving seat floor surface of the kind of the automobile to which the apparatus is to be fitted. Two sets of pin inserting holes are provided in the left side accelerator pedal 5 but may be changed to be in any number in response to the pedal height adjusting position.
As explained above, in the left side accelerator apparatus according to the present invention, when the left side accelerator pedal is lowered on the floor surface and is trodden in with the left foot, the same as in the case of treading in the ordinary accelerator pedal, the accelerator will be able to be operated. Also, the apparatus can be fitted and removed by a simple one touch operation without using any tool. Further, the apparatus as fitted is prevented by a fitted spring from dropping and is therefore safe. In case the ordinary driver operates the accelerator by using the automobile side accelerator pedal, in the conventional left side accelerator apparatus, the apparatus housed on the floor surface will interfere with the foot and it has been necessary to be nervous in operating the brake. However, in the present invention, the left side accelerator apparatus body can be removed from the automobile and therefore the ordinary accelerating operation and braking operation will not be influenced. Further, the automobile side accelerator pedal and right side arm are shielded on the front side by the shielding plate and therefore the automobile side accelerator can be prevented from operating irrespective of the left side accelerator operation by any force (such as the contact with the right foot or the drop of an object).
