It is not intended that the technical spirit and scope of the invention be limited.
도 2 내지 도 5에 도시된 본 발명의 일 실시예에 의한 각도 가변조절이 가능한 건설기계용 보조 페달은,2 to 5, the auxiliary pedal for a construction machine capable of variable angle control according to an embodiment of the present invention,
건설기계의 주행 페달 좌,우측에 위치하도록 운전실캡의 바텀플레이트에 장착되는 보조 페달에 있어서,In the auxiliary pedal mounted on the bottom plate of the cab cap so as to be located to the left and right of the traveling pedal of the construction machine,
운전실캡의 바텀플레이트(10) 상에 장착되며, 호 형상을 이루어 상하방향으로 반복형성되는 걸림홈(11)이 일측에 구비되는 하부 풋레스트(lower foot rest)(12)와,A lower foot rest 12 mounted on the bottom plate 10 of the cab cap and having a locking groove 11 formed in an arc shape and repeatedly formed in a vertical direction;
힌지(13)에 의해 하부 풋레스트(12)의 타측에 회동가능하게 연결되며, 걸림홈(11)에 결합되는 위치에 따라 보조 페달(14)의 각도를 가변 조절하는 조절간(15)이 바닥면에 구비되는 상부 풋레스트(upper foot rest)(16)로서 이뤄진다.The hinge 13 is rotatably connected to the other side of the lower footrest 12, and an adjustment interval 15 for variably adjusting the angle of the auxiliary pedal 14 according to the position coupled to the locking groove 11 is provided. It consists of an upper foot rest 16 provided on the face.
이때 바람직하게는, 전술한 상부 풋레스트(16)의 조절간(15)은In this case, preferably, the adjustment period 15 of the upper footrest 16 described above is
걸림홈(11) 형상과 대응되는 형상의 걸림턱(17)이 구비되는 판 형상의 탄성부재로 이뤄진다.It consists of a plate-shaped elastic member is provided with a locking step 17 of the shape corresponding to the shape of the locking groove (11).
전술한 걸림홈(11)은 기어이빨 형상으로 형성된다.The aforementioned locking groove 11 is formed in a gear tooth shape.
전술한 조절간(15)의 상단을 하부 풋레스트(12)의 바닥면에 돌출형성되어 걸림홈(11)과 대향되는 안착면(18)에 고정하되, 조절간(15)의 하단은 자유단으로서 안착면(18)에 밀착되어 지지된다.The upper end of the control section 15 is formed to protrude on the bottom surface of the lower footrest 12 to be fixed to the seating surface 18 facing the locking groove 11, the lower end of the control section 15 is a free end As a result, it is held in close contact with the seating surface 18.
전술한 보조 페달(14)은 예각 범위내에서 각도 가변 조절된다.The above-described auxiliary pedal 14 is angularly adjustable in the acute range.
이하에서, 본 발명의 일 실시예에 의한 각도 가변조절이 가능한 건설기계용 보조 페달의 사용예를 첨부도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings an example of the use of the auxiliary pedal for the construction machine capable of variable angle control according to an embodiment of the present invention.
도 2 및 도 3에서와 같이, 운전실캡의 바텀플레이트(10) 위에 하부 풋레스트(12)를 장착하되, 힌지(13)에 의해 하부 풋레스트(12)에 대해 상부 풋레스트(16)를 회동가능하게 연결한다. 이때 하부 풋레스트(12)의 호 형상을 이루는 걸림홈(11)에 이와 대응되게 형성된 상부 풋레스트(16)의 조절간(15)이 결합된다. 즉 조절간(15)은 힌지(13)를 중심축으로 원운동을 하게 되므로, 조절간(15)의 걸림턱(17)이 걸림홈(11)을 따라 상,하 방향으로 이동될 수 있다.2 and 3, the lower footrest 12 is mounted on the bottom plate 10 of the cab cap, and the upper footrest 16 is pivoted with respect to the lower footrest 12 by the hinge 13. Connect as much as possible. At this time, the control section 15 of the upper footrest 16 formed to correspond to the engaging groove 11 forming the arc of the lower footrest 12 is coupled. That is, since the adjustment section 15 is circular motion about the hinge 13, the locking step 17 of the adjustment section 15 can be moved in the up and down directions along the locking groove 11.
도 2, 도 4 및 도 5에서와 같이, 운전시 운전자의 신체적인 조건에 맞는 각도를 유지하도록 보조 페달(14)의 각도를 가변 조절할 수 있다. 상부 풋레스트(16)의 앞쪽(운전석시트로부터 멀리 떨어진 쪽을 말함)을 파지하여 상방향으로 들어올림에 따라, 상부 풋레스트(16)는 힌지(13)를 중심축으로 반시계방향으로 회동하게 된다.As shown in FIGS. 2, 4 and 5, the angle of the auxiliary pedal 14 may be variably adjusted to maintain the angle that matches the physical condition of the driver during driving. As the front of the upper footrest 16 is lifted upwards by grasping the front side of the upper seat restrained from the driver's seat, the upper footrest 16 rotates the hinge 13 counterclockwise about its central axis. do.
즉 상부 풋레스트(16)의 조절간(15)은 힌지(13)를 중심축으로 원운동함에 따라, 하부 풋레스트(12)의 걸림홈(11)을 따라 미끄러져 상방향으로 이동하게 된다. 따라서 운전시(주행장치가 정지된 상태에서 작업장치 또는 선회장치를 구동시키는 상태를 말함) 운전자의 신체적인 조건에 맞도록 소정각도로 회동된 상부 풋레스트(16) 위에 운전자 발을 올려놓게 됨에 따라 안정된 운전자세를 확보할 수 있게 된다.That is, as the adjustment section 15 of the upper footrest 16 circularly moves around the hinge 13 as the central axis, the adjustment section 15 slides along the locking groove 11 of the lower footrest 12 to move upward. Therefore, the driver's foot is placed on the upper footrest 16 rotated at a predetermined angle to meet the physical condition of the driver during driving (that is, driving the work device or the turning device while the driving device is stopped). A stable driver's tax can be secured.
도 2 및 도 5에서와 같이, 전술한 바와 같이 힌지(13)를 중심축으로 원운동하는 상부 풋레스트(16)의 조절간(15)이 탄성력을 갖는 판 형상의 탄성부재로 이뤄져 있다. 즉 상부 풋레스트(16)의 안착면(18)에 일단이 고정되고 타단이 자유단으로 지지된 조절간(15)이 스프링을 역할을 하게 된다(도 5에 점섬으로 표기됨). 따라서 탄성부재로 이뤄진 조절간(15)이 상부 풋레스트(16) 상면쪽으로 가해지는 충격을 흡수하게 된다. 이로 인해 상부 풋레스트(16) 위에 운전자 발을 올려놓을 경우, 운전자의 발목 및 무릎의 관절에 전달되는 충격을 감소시켜 준다.2 and 5, as described above, the adjusting section 15 of the upper footrest 16 circularly moving around the hinge 13 is made of a plate-shaped elastic member having elastic force. That is, the control section 15 having one end fixed to the seating surface 18 of the upper footrest 16 and the other end supported by the free end acts as a spring (indicated by a point island in FIG. 5). Therefore, the control section 15 made of an elastic member absorbs the shock applied to the upper surface of the upper footrest 16. This reduces the impact transmitted to the joints of the driver's ankle and knee when the driver's foot is placed on the upper footrest 16.
전술한 바와 같은 본 발명의 일 실시예에 의한 각도 가변조절이 가능한 건설기계용 보조 페달에 의하면, 운전시 운전자의 신체적인 조건에 맞도록 보조 페달의 각도를 조절하여 발을 올려놓음에 따라 최적의 운전자세 확보로 피로감을 줄일수 있다. 장시간동안 운전하는 운전자의 발목 또는 무릎의 관절을 보호할 수 있다. 보조 페달의 각도를 운전자 편의에 맞도록 조절함에 따라 다양한 각도의 시야를 확보할 수 있다.According to the auxiliary pedal for a construction machine capable of variable angle control according to an embodiment of the present invention as described above, by adjusting the angle of the auxiliary pedal to fit the physical conditions of the driver during driving, the optimum according to the foot You can reduce fatigue by securing a driver's tax. It protects the ankle or knee joint of the driver who drives for a long time. By adjusting the angle of the auxiliary pedals to suit the driver's comfort, it is possible to obtain various angles of view.
