본 고안은 입승식(立乘式) 지게차의 발판쿠션장치에 관한 것으로, 더욱 상세하게로는 기체의 바닥판과 발판사이에 소정의 탄성재를 매개하여 기체 주행중 지면으로부터 전달되는 진동을 이 탄성재에서 흡수하도록 한 입승식 지게차의 발판쿠션장치에 관한 것이다.The present invention relates to a foot cushion device of a lift type forklift truck, and more particularly, to the vibration material transmitted from the ground during the driving of the aircraft by a predetermined elastic material between the base plate and the foot plate of the body. It relates to a step cushion device of a forklift forklift to absorb in the.

종래 입승식 전동지게차의 발판은 제1도에 도시한 바와 같이, 통고무타이어(11)에 의해 지지된 기체(12)의 바닥판(13)상에 고정장착되어 있는 것이 일반적이었다. 즉 발판(14)과 바닥판(13)의 복수개소에 접시머리볼트(15)를 박아서 양자를 밀착고정하였다.As shown in FIG. 1, the footrest of the conventional passenger electric forklift is fixedly mounted on the bottom plate 13 of the base 12 supported by the tong rubber tire 11. That is, the plate head bolt 15 was put in the several places of the footrest 14 and the bottom plate 13, and both were fixed closely.

그러나, 이와 같은 종래의 구조는, 기체(12) 주행중 지면으로부터 전해지는 진동이 전혀 완충되지 못한채 통고무타이어(11)와 바닥판(13)을 통해 발판(14)까지 그대로 전달되는 단점이 있었다. 따라서, 이 발판(14)위에 선자세로 작업하여야 하는 작업자는 반복적인 진동과 미세한 충격으로 매우 쉽게 피로감을 느끼게 되며, 이러한 작업이 장시간 계속되면 관절부위에 무리가 가해져서 결국 관절염, 디스크 등의 직업병까지 유발하게 되는 폐단이 있었다.However, such a conventional structure has a disadvantage that the vibration transmitted from the ground while traveling the body 12 is not buffered at all and is transmitted as it is to the scaffold 14 through the tong rubber tire 11 and the bottom plate 13. Therefore, the worker who has to work on the scaffolding 14 on the scaffold 14 feels fatigue very easily by repeated vibration and minute shock, and if such work is continued for a long time, the joints are exerted and finally, occupational diseases such as arthritis and discs. There was a defect caused by.

특히, 고르지 않은 지반위에서 작업하게 되거나, 지게차의 주행이 동범위가 비교적 넓은 작업환경하에서 작업하게 되는 경우, 이와 같은 문제점은 더욱 심각하게 대두되었다.In particular, when working on uneven ground, or when the forklift is working in a relatively wide working environment, such a problem is more serious.

상술한 바와 같이 종래의 문제점을 감안하여 이루어진 본 고안은, 지게차 주행시 지면으로부터 발판에 전달되는 진동을 완충흡수하여 작업능률을 향상시키고 운전자를 각종 직업병으로부터 보호하는 입승식 지게차의 발판쿠션장치를 제공하는 데에 그 목적을 둔다.The present invention made in view of the conventional problems as described above, to provide a foot cushion device of a lift-type forklift truck that absorbs vibration transmitted from the ground to the scaffold when driving the forklift to improve work efficiency and protect the driver from various occupational diseases. The purpose is to

상술한 목적을 달성하기 위하여 본 고안의 발판쿠션장치는, 기체의 바닥판상에 발판이 지지되는 입승식 지게차에 적용되며, 상기 바닥판과 발판사이에 설치되는 복수개의 탄성재와, 상기 탄성재를 정위치에 고정하며 상기 바닥판에 대한 상기 발판의 횡방향이동을 억제하는 위치고정수단으로 구성됨을 특징으로 한다.In order to achieve the above object, the scaffolding device of the present invention is applied to a lift-type forklift truck on which a scaffold is supported on a bottom plate of a body, and a plurality of elastic members installed between the bottom plate and the scaffold, and the elastic material. It is characterized in that it is composed of a position fixing means for fixing in the fixed position to suppress the lateral movement of the footrest relative to the bottom plate.

이하, 첨부한 도면을 참조하여 본 고안의 바람직한 실시예에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

제2도는 본 고안의 일실시예에 의한 발판쿠션장치를 나타내고 있는데, 통고무타이어(11)에 의에 지지된 기체(12)의 바닥판(13)의 복수개소에 습동공(1, 1')의 위치와 대응되도록 복수개의 습동부재(2, 2')가 장착된다. 이 습동부재(2, 2')는 바닥판(13)에 대해 발판(14)의 횡방향 이동을 억제하게 된다. 그리고, 이 습동부재(2, 2')와 습동공(1, 1')사이에는 코일스프링(3, 3')이 설치되며, 이 코일스프링(3, 3')에 의해 전술한 발판(14)은 바닥판(11)으로부터 소정거리만큼 부상된 채 탄력적으로 지지된다.2 shows a scaffold cushioning apparatus according to an embodiment of the present invention, wherein the sliding holes 1, 1 'are provided at a plurality of locations of the bottom plate 13 of the base 12 supported by the tong rubber tire 11. A plurality of sliding members (2, 2 ') is mounted to correspond to the position of. These sliding members 2 and 2 'suppress the lateral movement of the footrest 14 with respect to the bottom plate 13. Coil springs 3 and 3 'are installed between the sliding members 2 and 2' and the sliding holes 1 and 1 ', and the above-described footholds are formed by the coil springs 3 and 3'. 14 is elastically supported while being raised from the bottom plate 11 by a predetermined distance.

이와 같이 구성된 본 실시예의 발판쿠션장치는, 기체(12)주행시 지면으로부터 전해지는 진동과 충격이 이 코일스프링(3, 3')에서 대부분 흡수될 수 있으므로, 발판(14)까지 전해지는 진동을 극히 적으며, 설사 진동이 전해진다 하더라도 그 파형이 예리하지 않으므로, 인체에 주는 피해는 거의 없다.The footrest cushioning apparatus of the present embodiment configured as described above is extremely capable of absorbing vibrations transmitted to the footrest 14 since vibrations and impacts transmitted from the ground when the body 12 is driven can be absorbed in most of the coil springs 3 and 3 '. It is small and even if the vibration is transmitted, the waveform is not sharp, so there is little damage to the human body.

한편, 전술한 코일스프링(3, 3')의 탄성계수는 충분한 완충효과를 발휘할 수 있는 탄성계수와 적업자의 평균체중을 고려하여 선택되는 것이지만, 작업자의 체중이 과도하여, 코일스프링(3, 3')의 수축한도를 벗어나게 되는 경우, 바닥판(13)으로부터 발판(14)를 분리한 후, 이 코일스프링(3, 3')을 쉽게 교체할 수도 있다.On the other hand, the above-described elastic modulus of the coil spring (3, 3 ') is selected in consideration of the elastic modulus that can exhibit a sufficient buffering effect and the average weight of the worker, but the weight of the worker is excessive, the coil spring (3, In the case of moving out of the contraction limit of 3 '), the coil springs 3 and 3' may be easily replaced after separating the footrest 14 from the bottom plate 13.

제3도는 본 고안의 다른 실시예에 의한 발판쿠션장치를 나타내고 있는데 본 실시예는 발판(14)와 바닥판(13)사이에 고무등의 탄성체(4, 4')를 매개하여 이루어진다. 즉, 발판(14)저면에 복수개의 볼트축(5, 5')이 장착되며, 이 각각의 볼트축(5, 5')에 탄성체(4, 4')가 끼워지며, 볼트축(5, 5')하단부에 워셔(6, 6')와 너트가 체결된다. 이 탄성체(4, 4')의 대략 중간부 외주에는 안착홈(8, 8')이 형성되고, 바닥판(13)에는 전술한 안착홈(8, 8')의 외경과 거의 동일한 내경을 갖는 관통공(9, 9')이 형성됨에 의해, 이 탄성체(4, 4')가 바닥판(13)의 관통공(9, 9')을 통해 압입된 후, 전술한 안착홈(8, 8')에 걸려 지지된다. 발판(14) 저면에 장착된 전술한 볼트축(5, 5')으로 인해 바닥판(13)에 대한 발판(14)의 횡방향이동이 억제된다.3 shows a scaffold cushioning apparatus according to another embodiment of the present invention, which is performed between the scaffold 14 and the bottom plate 13 through an elastic body 4, 4 'such as rubber. That is, a plurality of bolt shafts 5 and 5 'are mounted on the bottom of the scaffold 14, and elastic bodies 4 and 4' are fitted to the bolt shafts 5 and 5 ', respectively. 5 ') the washers 6 and 6' and the nut are fastened to the lower end. The recesses 8 and 8 'are formed in the outer periphery of the substantially intermediate portion of the elastic bodies 4 and 4', and the bottom plate 13 has an inner diameter that is substantially the same as the outer diameter of the above-mentioned mounting grooves 8 and 8 '. By forming the through holes 9 and 9 ', the elastic bodies 4 and 4' are press-fitted through the through holes 9 and 9 'of the bottom plate 13, and then the above-mentioned mounting grooves 8 and 8 ') Is supported. The above-described bolt shafts 5 and 5 'mounted on the bottom of the footrest 14 suppress the lateral movement of the footrest 14 relative to the bottom plate 13.

본 실시예의 발판쿠션장치 역시, 기체(12)주행시 지면으로부터 전해지는 진동과 충격이 탄성체(4, 4')에서 대부분 흡수될 수 있다.In the footrest cushioning apparatus of the present embodiment, vibrations and shocks transmitted from the ground when the body 12 is driven can be mostly absorbed by the elastic bodies 4 and 4 '.

이상 설명한 바와 같이 본 고안은 지게차 주행시 지면으로부터 발판에 전달되는 진동과 충격을 완충흡수하여 작업자가 느끼는 피로를 덜어줌으로써 작업능률을 향상시키고 각종 직업병으로부터 보호할 수 있는 효과가 있다.As described above, the present invention absorbs vibrations and shocks transmitted from the ground to the scaffold when driving the forklift, thereby reducing the fatigue of the worker, thereby improving work efficiency and protecting against various occupational diseases.
