_tailed Description of the Invention Fig.2 shows a pedal for an automobile of the present invention having a controller for controlling the radius of gyration of a pedal plate 42. The controller is constructed so -that a slot 91' is formed on a pedal lever member 91 rotatably `~ ~ -supported to the frame of an automobile, and an extension lever 75, in which a slot 75' is formed corresponding to slot 91' of pedal Iever member 91, is formed on pedal plate 42.
; Pedal lever member 91 and extension lever 75 are placed so as to oppose each other at a predetermined position and are fixed ~; together with a fastening member via the slots. Here, the ~ fastening member is comprised of a bolt 100 and a nut 101 ~ ;
;~ 20 coupled to slots 91' and 75', as shown in Fig.2.
; In order to prevent extension lever 75 from slipping on pedal lever member 91, as shown in Fig.3, protrusions 91~ and 75" are formed on the contact surfaces of pedal lever member 91 and extension member 75. -~-~25 Fig.4 shows another embodiment of the controller of the present invention.
Referring to Fig.4, a pedal lever member rotatably ''~': ' ' Z~3037~ ~ ~
:.. ` :"'~' supported to the ~rame of an automobile is construct~d so that a circular rod 90 is formed with a female screw 92. An ~ -. ..
extension rod 79 with a male screw 78 is provided on pedal plate 42 which tle driver's ~oot touches, so as to be coupled ~
with circular rod 90. Here, if pedal plate 42 rotates, the ~ ~;
radius of gyration of pedal plate 42 is varied as extension rod 79 is screwed into or unscrewed from circular rod 90.
Meanwhile, a nut 72 is coupled to extension rod 79 so as to prevent extension rcd 79 from unfastening on circular rod 90. Extension rod 79 is located at a position of circular rod - ;~
90 by rotating extension rod 79, and nut 72 is tightened to be in contact with the end of circular rod 90. The loosening of extension rod 79 is prevented due to the fastening force of ~;
nut 72. After pedal plate 42 is controlled to have a ~
15 ~ predetermined radius of gyration, the controlled state is ~ ~ `
stably maintained by the coupling of nut 72.
Fig.5 shows still another embodiment of the controller.
Referring to Fig.5, a slot 201 is formed on the side of a ~ -pedal levér~member 200 rotatably supported to the frame of 20~ automobile. A plurality of protrusions 202 are formed on the top of the pedal lever member. A hollow lever 211 having a coupllng hole 217 to which pedal lever member 200 is connected, is extended from a pedal plate 210 which the - driver's foot touches. Holes 216, 212 and 213 respectively communicating with coupling hole 217 are formed on the top and either side of pedal lever member 200. A leaf spring 220 resiliently coming into contact with protrusions 202 is -~
coupled to hole 216. Insertion holes 214 and 215 to which a ~'~' 2~30379 leaf spring 220 is c~upled are ,ormed on the opposit walls o~
hole 216. In the sta'e in which hollow lever 211 is coupled to fixed pedal lever member 200, when hollow lever 211 moves, leaf spring 220 is elastically displaced while in contact with protrusions 202. Here, hollow lever 211 can stop temporarily at a predetermined position of pedal lever member 200.
Therefore, hollow lever 211 can be fastened with bolt 218 and nut 219 in the state in which hollow lever 211 stops stably at a desired position.
The above-explained pedal of the present invention has the following operation effects. Extension lever 75 is placed at an appropriate position on pedal lever member 91 and are fixed by bolt 100 and nut 101 so that the driver can operate pedal plate 42 when the distance between the driver and the ~lS steerlng wheel or dashboard is appropriately controlled according to the leg length of the driver. Under these circumstances, it is easy ~or the driver to observe the forward and rear areas and convenient to operate the dashboard instrumentation while driving.
: , .
~20 Meanwhile, a pedal-length controller of the present invention is constructed as follows. ~-~
~-~ Referring to Fig.6, the controller comprises a pedal lever member 11 rotatably supported to the frame of an automobile, a pedal plate 12 fixed thereto, an auxiliary pedal -member 30 to be connected to pedal plate 12, and connection means for connecting pedal plate 12 and auxiliary pedal member -- 30. - -~
The conne~tion means comprises a coupling member 21 2~3~379 ~:
conn~cted to pedal piate 12, a fastening member such as a bolt 60 and nut 61 for fixing auxiliary pedal member 30 to coupling member 21. A connection lever 22 in which a slot 23 is formed is extendedly formed on coupling member 21. Auxiliary pedal member 30 has a control lever 31 in which a slot 33 is formed corresponding to connection lever 22, and an operation plate 32 fixed to control lever 31.
Here, coupling member 21 is shaped such that pedal plate 12 is received thereinto, as shown in Fig.6. A slit 24 into which pedal lever member 11 is inserted is formed thereon as -shown in Fig.7. The coupling member 21 is fixed;to pedal plate 12 with bolt and nut 51 as shown in Figs.6 and 7.
As shown in Fig.8, connection member 121 can be -constructed to have a plate 128 fixed to the end of connection ; -15 ~ lever 122 and an additional auxiliary plate 129 so as to be -~
. ~
directly fastened to pedal plate 112 with bolt 150 and nut - 151. This ~wo-piece connection member is easier to manufacture than the aforementioned connection member of Figs.5 and 6.
As shown in Fig.9, through-holes 25 and 35 through which bolt 60 passes may be formed on connection lever 22 and . ";
control lever 31 at predetermined intervals. This allows auxiliary pedal member 30 to be appropriately fixed at connection member 20. In this case, in which through-holes 25 ; A,.'', ~'.'' and 35 are formed along connection lever 22 and control lever 31 so that they may be fastened with bolt 60, a potentially ~ - `
.
hazardous situation during driving can be prevented since `~ control lever 31 is supported to connection lever 22 by bolt ;~
60 even when bolt 60 becomes partially unfastened.

lever 22 (122) and control lever 31 (131) so as to prevent ; control lever 31 and 131 fastened with bolt 60 ard nu~ 61 from sliding on connection lever 22 and 122. -Meanwhile, protrusions 32', as shown in Fig.11, are formed on operation plate 32 of auxiliary pedal member 30 so that when the driver operates operation plate 32, his or her foot does not slide thereon.
~10 Fig.12 is an exploded perspective view of another embodiment of the pedal-length controller of the present invention. Reference numeral 260 is a connection portion coupled to a pedal plate 250. Protrusions 261 are formed on ~ -~
the top of a connection lever 265 extended from connection portion 260. A hollow lever 271 to which connection lever 265 ~- is coupled is extended from an auxiliary pedal member 270. A
leaf spring 280 in contact with protrusions 261 are coupled to the top of lever 271. This embodiment is similar to that of Fig.5, whose operation will not be described.

Further, the height of auxiliary pedal member 30 can be controlled in accordance with the angle of the driver' 5 legs 10 at which driving is performed most comfortably for a given driver.
As described above, the present invention has the following advantages: first, automobile operation can be ~; -performed at a position where a driver is able to observe `~
~1~ 15 forward and rear areas at the same time, by controlling the radius of gyration of the auxiliary pedal member; second, the ~ -radius of gyration of the auxiliary pedal member can be
Meanwhile, if the driver undertakes to drive with driver's seat 3 pushed too far back for the length of his or her legs, the driver operates the pedals with his or her legs `~
overly extended, which quickens leg fatigue during long trips.
In an attempt to remedy this situation, drivers often fix driver's seat 3 at a position forward enough so that the pedal is easy to operate, and then leans the seat back 4 in order to -increase the distance between his or her upper body and the ~ - - -;
