Detailed Description

It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices illustrated in the attached drawings, and described in the specification are simply exemplary embodiments of the inventive concepts disclosed and defined herein. Thus, unless otherwise expressly stated, specific guide paths, directions or other physical characteristics referred to by the various embodiments disclosed should not be considered limiting.

The length-adjustable pedal 100 and the pedal mechanism 1000 according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1-3 respectively show schematic perspective views of a pedal mechanism 1000 according to a non-limiting embodiment of the present invention, viewed from different angles.

As shown, the example pedal mechanism 1000 may include pedal 100, pedal spindle 200, and pedal cover 300 arranged in pairs, wherein the pedal spindle 200 is pivotally supported on the pedal cover 300, and the pedal 100 is able to pivot about the pedal spindle 200.

Fig. 4-5 respectively show schematic perspective views of a pedal mechanism 1000 according to a non-limiting embodiment of the present invention, viewed from different angles, wherein the pedal cover 300 and other unrelated structures have been removed to better illustrate the structure of a pedal 100 according to the present invention.

As shown, the pedal 100 may include: a first pedal half 10 in the form of a rear pedal, a second pedal half 20 in the form of a front pedal, and a pedal adjusting mechanism 30, wherein the second pedal half 20 has a shape complementary to the first pedal half 10 in order to form the outer contour of the complete pedal 10. The first pedal half 10 is attached to the pedal spindle 200 to pivot or swing back and forth about the pedal spindle 200. In addition, optionally, the first pedal half 10 and the second pedal half 20 may further each comprise a pedal baffle extending upward from the upper surface of the pedal body at the front end and the rear end, so that the pedal 100 better receives the foot of an operator, such as a pilot, so as to better operate the pedal 100 with the foot and to save the effort of the person required for the operation.

The first pedal half 10 and the second pedal half 20 can be made of any material known in the art by any manufacturing method, as long as they are capable of being form-fitted together to form the complete pedal 100. However, in an alternative embodiment, the first pedal half 10 and the second pedal half 20 may not form the complete contour of the pedal 100, but only a partial contour thereof, without affecting the pedal function, for the purpose of saving material, reducing weight, etc.

With continued reference to fig. 4-5, the example pedal adjustment mechanism 30 may include a first guide 31 attached to the first pedal half 10, a second guide 32 attached to the second pedal half 20, and a locking mechanism 33. As shown, the first guide portion 31 may be in the form of a slide groove, and the second guide portion 32 may be in the form of a slide rail, so that the second guide portion 32 can be fitted into the first guide portion 31 to be reciprocally moved in the length direction of the pedal 100 with respect to the first guide portion 31. The locking mechanism 33 may be used to lock the position of the second guide portion 32 relative to the first guide portion 31.

In accordance with a preferred embodiment of the present invention and as a non-limiting example, the pedal adjusting mechanism 30 can further include an actuating mechanism 34 and a transmission mechanism 35 driven by the actuating mechanism 34, and the transmission mechanism 35 is drivingly connected to the locking mechanism 33 to selectively lock or unlock the locking mechanism 33. In the example shown in the drawings, the actuating mechanism 34 is shown in the form of a handle 340 (which will be described in more detail later), i.e. the transmission 35 is driven by the pilot manually pulling the handle 340. In alternative embodiments, the actuating mechanism 34 may be in other configurations, such as in the form of an electric motor, to automatically drive the transmission 35 such that the locking mechanism 33 is selectively locked or unlocked, i.e., released when the length of the step pedal 100 needs to be adjusted, and locked at an initial state and when adjusted to a desired length.

According to a preferred embodiment of the present invention and as a non-limiting example, the locking mechanism 33 comprises a pin 331 attached to the first guide portion 31 and a plurality of card slots 332 attached to the second guide portion 32, wherein the pin 331 is adapted to fit into any one of the plurality of card slots 332, and wherein the transmission mechanism 35 is connected to the pin 331 of the locking mechanism 33. A specific configuration of the plurality of card slots 332 is shown in fig. 6, and as shown, the card slots 332 may be in the form of concave semicircular grooves with side walls having a slope. A plurality of notches 332 can be provided on the slide rail of the second pedal half 20, for example, with adjacent notches 332 being adjacent to each other and closely spaced such that when the pin 331 is between two notches 332, the pin 331 can automatically slide into the adjacent notch 332 along the slope of the sidewall of the notch 332 to prevent the pedal from failing to lock in a predetermined position and failing to cause an accident. The pin 331 may be any pin known in the art, such as a cylindrical pin, a square pin, etc., but is preferably a cylindrical pin having a size corresponding to the recess of the card slot 332, and having a conical insertion end to more conveniently fit into the card slot 332.

According to a preferred embodiment of the invention and as a non-limiting example, the first pedal half 10 may further comprise a limiting groove 11, which limiting groove 11 may cooperate with, for example, a stop 212 on the second pedal half 20 to limit the maximum displacement of the second pedal half 20 with respect to the first pedal half 10, so as to limit the maximum effective length of the pedal 10, for example, to limit this effective length in the range of 22 cm to 32 cm, preferably in the range of 24 cm to 30 cm, so as to reduce the distance that needs to be adjusted/moved as little as possible while ensuring accommodation of the feet of the pilot (including the shoes worn by the pilot).

According to a preferred embodiment of the present invention and as a non-limiting example, the second pedal half 20 may further comprise a return mechanism 21, the return mechanism 21 being able to be accommodated in the limiting groove 11 and exerting a return force on the first pedal half 10 and the second pedal half 20 moving towards each other. By means of this restoring force, the first pedal half 10 and the second pedal half 20 are always pulled against each other to adapt to the passive adjustment of the feet of the pilot. In an alternative embodiment, the return mechanism may apply a return force to the first pedal half 10 and the second pedal half 20 away from each other. At this time, the pilot needs to push the second pedal half 20 towards the first pedal half 10 at each adjustment to adjust the pedal 10 to the proper length range.

Preferably and with continued reference to fig. 5 and 6, the example return mechanism 21 may comprise a guide bar 210 and a tension spring 211 disposed around the guide bar 210, wherein one end of the tension spring 211 is attached to the first pedal half 10 and the other end of the tension spring 211 is attached to the second pedal half 20.

In accordance with another preferred embodiment of the present invention and as shown in detail in fig. 7-8, the actuating mechanism 34 may include a handle 340 and a handle mount 341, and the transmission mechanism 35 includes a first cable 351, one end of the first cable 351 being attached to the handle 340 and the other end of the first cable 351 being attached to the locking mechanism 33 such that a change in position of the handle 340 relative to the handle mount 341 causes the first cable 351 to selectively lock or unlock the locking mechanism 33. For example, movement of the handle 340 relative to the handle mount 341 in the axial direction locks or unlocks the locking mechanism 33, for example by means of a not shown elastic return element (tension and compression spring, etc.). In an alternative embodiment, movement of the handle 340 relative to the handle mount 341 in a circumferential direction locks or unlocks the locking mechanism 33

Fig. 9-12 show schematic views of adjusting the length of the footrest 100 in the preferred embodiment. In fig. 9, the lock mechanism 33 is in the locked state, and the pedal 100 is in the initial state. In fig. 10, the locking mechanism 33 is released by pulling the handle 340, thereby moving the pin 331 away from the catch 332. In fig. 11, the lock mechanism 33 is in a released state, and the second guide portion 32 can slide on the first guide portion 31. At this point, a user, for example a pilot, can manually adjust the position of the second pedal half 20 using both feet so that the length of the pedal 100 exactly matches the length of his feet. In fig. 12, the handle 340 is pushed back into the handle mount 341, so that the first cable 351 is retracted by a not-shown returning means, thereby reinserting the pin 331 into the card slot 332, that is, the locking mechanism 33 is returned to the locked state. At this time, the step pedal 100 is locked at the adjusted length, thereby completing one length adjustment of the step pedal. The above operation steps may be repeated when another pilot needs to adjust the length of the foot pedals 100.

According to another preferred embodiment of the present invention and as shown in detail in fig. 13-16, the transmission mechanism 35 may further include a second cable 352, and the second cable 352 is drivingly connected to the second guide portion 32 to adjust the position of the second guide portion 32 relative to the first guide portion 31. In a preferred embodiment, movement of the handle 340 relative to the handle mount 341 in the circumferential direction drives the second guide portion 32 to reciprocate relative to the first guide portion 31, for example by means of a resilient return element (torsion spring or the like), not shown. Preferably, a scale mark corresponding to the length of the step pedal 100 may be provided on the handle mount 341 to more conveniently and quickly adjust the step pedal 100 to a predetermined length. In an alternative embodiment not shown, movement of the handle 340 in the axial direction relative to the handle mount 341 drives the second guide portion 32 to reciprocate relative to the first guide portion 31.

Fig. 17-18 respectively show schematic perspective views of an actuation mechanism 34 from different angles, according to another non-limiting embodiment of the present invention. The actuation mechanism 34 is structurally different from the actuation mechanism 34 shown in the previous figures, but again includes a handle 340 and a handle mount 341.

Fig. 19-20 each show a schematic partial cross-sectional view of the actuation mechanism 34 shown in fig. 17. As shown, the handle 340 is a generally T-shaped mechanism including an upper generally horizontal portion to which the first cable 351 is attached and a generally vertical portion inserted into the handle mount 341, and the generally horizontal portion of the handle 340 may have a hole for a finger to catch, for example, so that the handle 340 can be easily pulled out with a single finger, thereby putting the locking mechanism 33 in a released state by means of the first cable 351.

With continued reference to fig. 20 and by way of non-limiting example, the actuation mechanism 34 further includes a pivot member 342 housed in the handle mount 341, the pivot member 342 including an upper generally vertical cylindrical portion and a lower disc-shaped capstan, wherein a guide slot 342A is provided in the cylindrical portion, and a second cable 352 may be attached to the capstan so as to be windable thereabout. In addition, as shown in the drawing, a guide block 340A is provided at a lower end of the substantially vertical portion of the handle 340 so that the guide block 340A can freely slide up and down in the guide groove 342A. With this structure, the handle 340 can freely move up and down relative to the pivoting member 342, and the rotational movement of the handle 340 will bring the pivoting member 342 to rotate together. When the handle 340 is pulled upward in this way, the lock mechanism 33 is released by the first cable 351, and the length of the pedal 100 can be adjusted by the second cable 352 by continuing to rotate the handle 340.

With continued reference to fig. 20 and by way of non-limiting example, the actuation mechanism 34 further comprises a tension spring 343 and a torsion spring 344 housed in the handle mount 341, the tension spring 343 being able to act as a return spring for the handle 340, so that the handle 340 retracts to an initial position in the handle mount 341 once the pilot releases the handle 340, in order to put the locking mechanism 33 in a locked state.

Fig. 21-22 show details of a portion of the actuation mechanism 34 including the pivot member 342 and the torsion spring 344. As shown, the torsion spring 344 may act as a return spring for the pivot piece 342, so that the second cable 352 always transmits a pulling force pulling the first pedal half 10 and the second pedal half 20 against each other.

While the present invention has been described with respect to fig. 17-22 for a preferred embodiment of the actuator mechanism 34, it should be understood that those skilled in the art can envision other alternative configurations so long as they can control both the first cable 351 and the second cable 352 of the transmission mechanism 35 as desired.

Preferably, the actuation mechanism 34 may also include an automatic adjustment mechanism, which may include, for example, a motor (e.g., an electric motor) drivingly attached to the first cable 351 and/or the second cable 352 to tighten or loosen the first cable 351 and/or the second cable 352 and a corresponding sensor (e.g., a position sensor) that may be used to detect whether the foot pedal 100 has been adjusted into position. This schematic regulation control block diagram is shown in fig. 17. At this time, a corresponding control button may be provided at the handle mount 341 to control the operation of the motor. For example, when the button is pressed, in case the locking mechanism 33 has been released (e.g. by pulling out the handle 340 or, likewise, by the motor driving the first cable 351 to release the locking mechanism 33), the motor starts to operate to bring the second cable 352 to drive the second guide part 32 to move relative to the first guide part 31, i.e. to move the second pedal half 20, and when moved to the appropriate position, the button is released and the length adjustment of the pedal 100 is completed.

In embodiments where the motor is attached to both the first cable 351 and the second cable 352, the motor may also be connected to a central control unit within the nacelle to more conveniently adjust the length of the foot pedal 100 on the human machine interface. In a further embodiment, the motor may be controlled by an ID tag corresponding to the pilot, such that upon recognition of the ID tag, the motor is activated to automatically adjust the length of the foot pedals 100 so that their length corresponds to a preset length of the pilot's feet.

It should be understood that the above description of the foot pedal 100 according to a non-limiting embodiment of the present invention can be equally applied to the left and right foot pedals of the foot pedal mechanism 1000. And preferably, the pedal adjusting mechanism 30 enables the left and right pedals to be operated in linkage, i.e., the lengths of the left and right pedals are adjusted in real time and synchronously. However, in alternative embodiments, the left foot pedal and the right foot pedal may be controlled independently to accommodate particular needs that may exist.

As used herein, two components that are "drivingly connected" may be used to mean that the two components are connected together and that one component is enabled to drive or actuate the other component. In addition, the terms "first" or "second", etc. used to indicate the order are only for making the concept of the present invention shown in the preferred embodiments better understood by those skilled in the art, and are not used to limit the present invention.
