제동을 위한 브레이크는 바퀴의 주위에 지지대를 설치하고, 고정시 지지대를 지면에 접촉되도록 하는 구조가 있고, 승강하는 지지대가 바퀴를 눌러 구름운동을 저지하는 구조가 있다.The brake for braking has a structure in which a support is installed around the wheel, and the support is brought into contact with the ground when fixed, and the lifting support is configured to prevent rolling by pressing the wheel.

상기 중 지지대를 지면에 접촉시키는 경우는 제동력이 불안하여 지지대를 바퀴보다 더 내려 바퀴가 지면에서 떨어지도록 하는 경우가 있는데 이 경우에는 많은 힘이 소요되는 문제점이 있다. 그리고 지지대를 바퀴에 접촉시켜 바퀴의 구름운동을 저지하는 경우는 작동하기가 매우 불편한 점이 있었다.When the support is in contact with the ground, the braking force is unstable, so that the support lower than the wheel may fall off the ground in this case there is a problem that takes a lot of force. In addition, there was a very inconvenient point of operation when the support was contacted with the wheels to prevent rolling motion of the wheels.

본 발명의 목적은 용이하게 바퀴를 고정하고, 고정된 상태가 확실하게 유지되는 구조를 제공함에 있다. 따라서 본 발명은 바퀴를 압지하여 고정시키는 압지레버와, 압지레버를 작동시키는 작동레버로 구성되고, 상기의 압지레버는 탄성력을 가짐으로써 제동력과 작동에 있어 매우 편리함을 제공하도록 함에 있다.An object of the present invention is to provide a structure in which the wheel is easily fixed and the fixed state is reliably maintained. Therefore, the present invention is composed of a pressure lever for pressing and fixing the wheel, and an operating lever for operating the pressure lever, the pressure lever is to provide a very convenient in braking force and operation by having an elastic force.

캐스터는 대차의 저면에 고정되는 플랜지와, 상기 플랜지의 하부에 베어링에 의해 회동되게 설치된 축지부(14)와, 상기 축지부(14)에 설치된 바퀴(1)로 구성되고, 상기 베어링의 중심과 바퀴(1)의 중심은 수직면에 대하여 일정 간격 이격된 구조이다.The caster is composed of a flange fixed to the bottom of the trolley, a bottom support portion 14 pivotally installed by a bearing in the lower portion of the flange, and a wheel (1) provided on the support portion 14, the center of the bearing and The center of the wheel 1 is a structure spaced apart at regular intervals with respect to the vertical plane.

본 발명에 의한 캐스터용 브레이크는 바퀴(1)의 회전축 양측에 일단부가 고정된 한쌍의 측부브라켓(2); 상기의 측부브라켓(2)의 타단부에 양측이 고정되고, 레버홈(3)이 형성된 상부브라켓(4); ∨형상으로 절곡되어 양측 단부가 고정단부(5)와 해제단부(6)로 형성되고, 절곡부의 양측에 형성된 삽입홈(7)에 의해 작동돌기(8)가 형성되며, 해제단부(6)가 상기 레버홈(3)에 끼워진 작동레버(9); 일측에는 탄성압지판(10)의 양측에 각각 돌기작동판(11)이 일정 간격 이격되게 형성되고, 상기 돌기작동판(11)의 끝단부는 상부로 절곡되어 단부돌기(12)가 형성되며, 상기 탄성압지판(10)은 돌기작동판(11)이 형성하는 면에서 이격되게 아래로 절곡되고, 타측은 상부브라켓(4)의 저면에 고정되며, 상기 두개의 돌기작동판(11)이 작동레 버(9)의 양측 삽입홈(7)에 각각 삽입되고, 단부돌기(12)가 작동돌기(8)에 걸치도록 설치된 압지레버(13);를 포함하여 구성됨을 특징으로 한다.The caster brake according to the present invention includes a pair of side brackets 2 having one end fixed to both sides of the rotation shaft of the wheel 1; An upper bracket (4) having both sides fixed to the other end of the side bracket (2) and having a lever groove (3); It is bent in a U-shape so that both ends are formed with a fixed end portion 5 and a release end portion 6, and an actuating projection 8 is formed by insertion grooves 7 formed at both sides of the bent portion, and the release end portion 6 is An actuating lever 9 fitted into the lever groove 3; On one side, each of the projection operation plate 11 is formed on both sides of the elastic pressure plate 10 to be spaced apart a predetermined interval, the end of the projection operation plate 11 is bent upwards to form an end projection 12, the The elastic pressure-sensitive plate 10 is bent downward to be spaced apart from the surface formed by the projection operation plate 11, the other side is fixed to the bottom of the upper bracket (4), the two projection operation plate 11 is the operating lever It is inserted into both sides of the insertion groove (7) of the burr (9), the end projection 12 is provided with a pressure lever (13) installed so as to span the working projection (8);

이와 같은 구조를 가진 본 발명은 도 1과 같은 상태로 되어 있고, 도 4와 도 5에 도시된 바와 같이 바퀴(1)를 고정하거나 해제하는 역할을 하게 된다.The present invention having such a structure is in a state as shown in FIG. 1, and serves to fix or release the wheel 1 as shown in FIGS. 4 and 5.

우선 축지부(14)와 측부브라켓(2)은 바퀴(1)의 회전축으로 연결되고, 또한 움직이지 않게 고정되어 있다. 즉 도 6에 도시된 바와 같이 바퀴(1) 회전축 부근의 축지부(14)에는 하나 이상의 고정공(15)이 형성되고, 측부브라켓(2)의 상기 고정공(15) 부분에는 고정돌기(16)가 형성되어, 상기의 고정공(15)과 고정돌기(16)의 결합으로 바퀴가 고정되는 구조이다.First, the bearing portion 14 and the side brackets 2 are connected to the rotating shaft of the wheel 1 and are fixed in a stationary manner. That is, as shown in FIG. 6, at least one fixing hole 15 is formed in the shaft portion 14 near the rotation axis of the wheel 1, and the fixing protrusion 16 is formed at the portion of the fixing hole 15 of the side bracket 2. ) Is formed, the wheel is fixed by the combination of the fixing hole 15 and the fixing protrusion 16.

브레이크의 기능을 제공하기 위한 설치 구조의 프레임은 한쌍의 측부브라켓(2)과, 이의 상부에 체결된 상부브라켓(4)이다.The frame of the installation structure for providing the function of the brake is a pair of side brackets 2 and an upper bracket 4 fastened to the upper portion thereof.

바퀴(1)의 고정은 압지레버(13)의 탄성압지판(10)이 바퀴(1)에 강하게 접촉됨으로써 달성된다. 이러한 압지력은 작동레버(9)에 의해 발생되고, 압지레버(13)의 탄성력에 의해 그 기능이 더욱 안정적으로 확보된다.The fixing of the wheel 1 is achieved by the strong contact of the elastic pressure plate 10 of the push lever 13 with the wheel 1. This holding force is generated by the operating lever 9, and its function is more stably secured by the elastic force of the pressing lever 13.

도 4와 같은 상태에서 바퀴(1)를 고정하고자 할 경우에는, 작동레버(9)의 일측 단부인 고정단부(5)를 누르면 된다. 작동레버(9)의 절곡부에는 작동돌기(8)가 양측에 돌출되어 있으므로, 이것이 압지레버(13)의 돌기작동판(11)의 단부에 형성된 단부돌기(12)에 걸려 회동의 축이 된다.When the wheel 1 is to be fixed in the state as shown in FIG. 4, the fixed end 5, which is one end of the operating lever 9, is pressed. Since the actuating projections 8 protrude on both sides at the bent portion of the actuating lever 9, they are caught by the end projections 12 formed at the end of the protruding actuating plate 11 of the pressing lever 13 to become an axis of rotation. .

따라서 작동레버(9)의 고정단부(5)를 계속 누르게 되면, 작동돌기(8)가 도 5에 도시된 바와 같이 입설되면서 작동이 멈추게 된다. 즉 작동돌기(8)에 의하여 압지레버(13)의 탄성압지판(10)이 바퀴(1)에 가압되어 바퀴(1)를 고정하게 된다. Therefore, when the fixed end 5 of the operation lever 9 is continuously pressed, the operation projection 8 is entered as shown in FIG. 5 and the operation is stopped. That is, the elastic pressure plate 10 of the push lever 13 is pressed by the wheel 1 by the actuating protrusion 8 to fix the wheel 1.

상기의 압지레버(13)는 상부브라켓(4)에 고정되어 있으므로, 이를 기점으로 하여 탄성력 있게 휘어지고, 특히 탄성압지판(10)이 돌기작동판(11)의 면보다 아래로 이격되게 절곡된 구조를 가짐으로써 이 또한 탄성압지판(10)의 탄성력을 부여하게 된다.Since the push lever 13 is fixed to the upper bracket 4, it is elastically bent from the starting point, and in particular, the elastic pressure plate 10 is bent so as to be spaced apart from the surface of the projection operating plate 11 below. By having this also gives the elastic force of the elastic pressure plate (10).

이와 같이 작동레버(9)의 간단한 작동으로 탄성압지판(10)이 바퀴(1)를 고정하게 되고, 압지레버(13)의 돌기작동판(11) 및 탄성압지판(10)의 탄성력이 작동레버(9)의 작동을 원활하게 해 줄 뿐만 아니라 고정 후에도 탄성력이 해제되려는 힘을 수용하여 쉽게 고정이 해제되지 않도록 하는 역할을 하게 된다.In this way, the elastic pressure plate 10 is fixed to the wheel 1 by the simple operation of the operating lever 9, the elastic force of the projection operating plate 11 and the elastic pressure plate 10 of the pressure lever 13 is operated. Not only facilitates the operation of the lever (9) but also serves to prevent the easy release by receiving the force to release the elastic force after fixing.

그리고 탄성압지판(10)의 바퀴(1)의 접촉부에는 다수개의 돌기가 형성되어 미그러짐을 방지하는 실시예도 가능하다.In addition, an embodiment in which a plurality of protrusions are formed at a contact portion of the wheel 1 of the elastic pressure plate 10 to prevent slippage is also possible.

바퀴(1)의 고정상태를 해제하고자 하는 경우는, 작동레버(9)의 해제단부(6)를 밀어주면 된다. 작동레버(9)의 양측 단부는 절곡되어 고정단부(5)와 해제단부(6)로 형성되어 있고, 고정단부(5)를 눌러 바퀴(1)를 고정한 상태에서는 해제단부(6)가 일어 서 있는 상태가 된다.In order to release the fixed state of the wheel 1, the release end 6 of the operation lever 9 may be pushed. Both ends of the actuating lever 9 are bent to form a fixed end 5 and a release end 6, and the release end 6 stands up while the fixed end 5 is fixed to the wheel 1 by pressing the fixed end 5. It is in a state.

따라서 해제하고자 할 경우에는 일어선 해제단부(6)를 밀어 주면, 압지레버(13)를 밀어 주고 있던 작동돌기(8)가 누워지게 되면서 압지레버(13)는 그 자체의 탄성력으로 원위치되면서 바퀴(1)에서 떨어지게 된다.Therefore, if you want to release the pushed up the release end (6), the operation projection (8) that was pushing the push lever 13 is laid while the push lever (13) is in its own elastic force to the original position of the wheel ( Fall from 1).

이와 같이 본 발명은 탄성력 있는 압지레버(13)를 작동레버(9)로써 간단하게 조작하여 캐스터의 바퀴(1)를 용이하게 고정하거나 해제할 수 있어, 다양한 용도로 사용되는 캐스트의 안정성이 확보되고, 해제가 쉽게 풀리는 문제를 해소하여 안전사고 등을 방지할 수 있게 된다.As described above, the present invention can easily fix or release the caster wheel 1 by simply operating the elastic force holding lever 13 as the operation lever 9, thereby securing the stability of the cast used for various purposes. In addition, it is possible to prevent safety accidents by solving the problem of easy release.
