Description

Foot pedal device

The present invention relates to a foot pedal device, and more particularly to a foot pedal device that is mounted on a carrier for stepping on an occupant's foot.

According to the present, the locomotives of the two-person locomotives are provided with pedals for the passengers to place on both sides of the locomotive rear seat, and the pedals can be folded and used for the pedals. At the same time, the foot pedal is pulled out from both sides of the vehicle body of the locomotive for use; therefore, in order to make the conventional pedals have better convenience in use and folding, the current operator Many improvements have been made to the conventional foot pedal.

Please refer to FIG. 1 , which is a foot pedal device 9 disclosed in the Patent No. I274005 of the Republic of China, the "Push-Opening Locomotive Rear Foot Pedal" patent. The conventional foot pedal device 9 is composed of a base. The seat 91 is mounted on the two sides of the vehicle body under the locomotive seat cushion. One side of the base 91 is provided with a recess 911, and is received in the recess 911 by a latching member 92, with a resilient member 921 The latching member 92 is pushed so that the latching member 92 can be latched on one of the positioning holes 931 of a pedal 93, so that the pedal 93 is fixed in position. The pedal 93 is pivotally connected to a pivot 912 of the base 91 by an assembly portion 932, and a torsion spring 94 and a swing arm 95 are sequentially mounted on the assembly portion 932 of the pedal 93; the torsion spring 94 is A cover plate 96 is disposed between the swing arms 95 for restraining and positioning the torsion spring 94 for providing the elastic force of the pedal 93 to elastically pivot. A positioning end 951 of the swing arm 95 is abutted against a protrusion 933 of the pedal 93. One positioning hole 952 of the swing arm 95 is pivotally connected to a pivoting member 971 of a cover body 97; Covering the base 91, thereby defining that the pedal 93 is pivotally located at the base 91 and the cover 97 In between, the swing arm 95 in the pedal 93 can be rotated with the internal movement of the pedal 93, thereby controlling the pedal 93 to assume a folded or unfolded state.

The above-described member assembly is completed to complete the conventional footrest device 9, such that when the pedal 93 is in the folded position, the latch member 92 is caught in the positioning hole 931 of the pedal 93, so that the pedal 93 The card fixing position; when the pedal 93 of the positioning state is pushed in the folding direction for pivoting, the swing arm 95 in the pedal 93 rotates with the internal movement of the pedal 93, thereby pushing the latch 92 upward. To release the click of the pedal 93, the pedal 93 is in an unfolded state. Accordingly, by the cooperation of the rotation of the swing arm 95 and the torsion spring 94, in the case where the pedal 93 itself is reversely operated, the pedal 93 in the positioned state can be automatically bounced.

However, when operating the above-described conventional footrest device 9, the user needs to turn the body to visually confirm where the conventional footrest device 9 is located in the locomotive body, so as to press against the appropriate operating position. The pop-up or retraction of the pedal 93 is controlled, so that it is still not convenient to use.

In addition, the Republic of China Announcement No. M336900 "Motorcycle Pedal", No. M329592 "Equipment for Automatically Pushing the Pedalboard", No. I294005 "Pushing Locomotive Pedal", No. M245139 Patent cases such as "Motorcycle Pedal Quick Assembly Mechanism", No. I243783 "Foot of the Locomotive" and No. M325967 "Equipment for Automatically Pushing the Pedal of the Pedestal" also have the same problem; therefore, The conventional foot pedal device does have to be improved.
