[0001] HINGE APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hinge apparatus, and more particularly, to a hinge apparatus capable of rotatably coupling a movable member to a support within a predetermined angle range.

Generally, the hinge device is a device for rotatably coupling a door such as a hinged door to a wall, a fixed frame, or the like. Such a hinge device is utilized in various fields such as construction, automobiles, and electronic products, and its structure is very diverse.

For example, as shown in FIG. 1, a so-called carriage on which a loading box is covered with a box-shaped cover is provided with a plurality of hinge apparatuses 20 for installing the loading door 10. The loader door 10 is rotatably installed at the edge of the box-shaped cover by a plurality of hinge devices 20 so as to be able to open and close the open rear of the box-shaped cover. The loader door 10 can be opened and closed by turning the opening portion of the box-shaped cover to the left and right by rotating the loader door 10 relative to the box-shaped cover by the hinge device 20. [ Such a loading door 10 can be locked with the loading box closed by a locking bar installed perpendicular to the ground.

The hinge unit 20 of the loading door 10 includes a fixing bracket 21 fixed to the box-shaped cover and a connecting piece 22 hinged to the fixing bracket 21 at one end and fixed to the loading door 10 at the other end. . The connecting piece 22 can be rotated with respect to the fixing bracket 21 with the hinge pin coupled to the fixing bracket 21 as a rotation center axis.

However, the conventional hinge device 20 is liable to be deformed during use for a long time, and the loader door 10 may be twisted to easily cause the door 10 to not be closed properly.

The hinge device 100 is used for rotatably coupling various types of movable bodies 200 such as a loading door of a truck to a supporting body 300 having various structures such as a supporting frame mounted on a truck.

The support bracket 110 has a base plate 111, a first post 116, and a second post 118. The support bracket 110 may be fixed to the support 300 through a fixing member 400 such as a bolt.

The base plate 111 is composed of a central portion 112 and a first wing portion 113 and a second wing portion 114. The center portion 112 is disposed between the first wing portion 113 and the second wing portion 114 and the first and second posts 116 and 118 are coupled to the center portion 112. The first wing portion 113 extends outward from one end of the center portion 112 so as to protrude laterally with respect to the outer surface of the first post 116. The second wing portion 114 extends outward from the other end of the middle portion 112 so as to protrude laterally with respect to the outer surface of the second post 118.

When the plurality of through holes 115 are eccentrically arranged on the base plate 111 and the base plate 111 is fixed to the support body 300 by the plurality of fixing members 400, It is possible to increase the supporting force of the supporting member 110. The movable member 200 can be more stably supported by the connecting member 130 by increasing the supporting force with respect to the connecting member 130 so that the phenomenon of the movable member 200 being twisted with respect to the supporting member 300 can be reduced, The stable operation of the movable body 200 can be induced. The number and arrangement of the through holes 115 are not limited to those illustrated and can be variously changed.

The first post 116 and the second post 118 of the support bracket 110 are disposed on one surface of the base plate 111 in an upright position. The first post 116 and the second post 118 may be fixed to the base plate 111 by welding or may be integrally formed with the base plate 111.

The second posts 118 are provided on the base plate 111 so as to extend in a curved shape from one side of the base plate 111 toward the upper side. That is, the second post 118 is formed in a gently curved shape so as to move away from the movable plate 200 while moving away from the base plate 111. The upper end of the second post 116 is located at a position deviating from the base plate 111 from the edge of the base plate 111 laterally.

The second shaft 118 is provided with a second shaft engagement hole 119. The second shaft engaging hole 119 is formed parallel to the first shaft engaging hole 117 at an upper end portion of the second post 118 which is laterally offset from the edge of the base plate 111. The direction in which the second shaft engagement hole 119 is formed is parallel to the base plate 111.

2 to 4, the support shaft 120 includes a first shaft engagement hole 117 and a second shaft engagement hole 117 respectively provided in the first post 116 and the second post 118 of the support bracket 110, And is disposed at a position deviating from the base plate 111 laterally from the edge of the base plate 111 by fitting into the engagement hole 119. The supporting shaft 120 is disposed in parallel with the base plate 111 and is coupled to the supporting bracket 110 to form a rotational center axis of the connecting member 130.

The support shaft 120 has a shaft body 121 and a head 123. The shaft body 121 is a portion to be inserted into the first shaft engagement hole 117 and the second shaft engagement hole 119 of the support bracket 110. At one side of the shaft body 121, a threaded portion 122 having a thread on the outer circumferential surface thereof is provided. The threaded portion 122 extends from one intermediate side of the shaft body 121 to one end of the shaft body 121. The head 123 is provided at the other end of the shaft body 121 so as to be wider than the outer diameter of the shaft body 121. The support shaft 120 is rotatably supported by the shaft body 121 such that the screw body 122 of the shaft body 121 is protruded to the outside of the first post 116 or the second post 118, The nut 125 may be screwed to the screw portion 122 so as to be coupled to the support bracket 110 while being inserted into the shaft coupling hole 117 and the second shaft coupling hole 119. [

The connection member 130 is rotatably coupled to the support bracket 110 through the support shaft 120 so as to be coupled to the movable body 200. The connecting member 130 includes a supporting bracket connecting portion 131, a movable body engaging portion 133, and a step connecting portion 135.

The support bracket connection portion 131 is rotatably coupled to the support bracket 110 through the support shaft 120. The movable body engaging portion 133 is engaged with the movable body 200. The movable body coupling portion 133 is provided with a plurality of through holes 134 into which the fixing member 400 for coupling with the movable body 200 can be inserted. The plurality of fixing members 400 are coupled to the movable body 200 through the plurality of through holes 134 so that the movable body coupling portion 133 can be firmly fixed to the movable body 200. [

One end of the step connection part 135 is connected to the support bracket connection part 131 and the movable body engagement part 133 is connected to the other end of the step connection part 135 so that the support bracket connection part 131 and the movable body engagement part 133 are stepped . Therefore, the connecting member 130 has a stepped structure which is bent several times as a whole. The step connection portion 135 includes a first connection portion 136 to be coupled to the support bracket connection portion 131 and a second connection portion 137 to be coupled to the movable body engagement portion 133. The first connection portion 136 is connected to the support bracket coupling portion 131 at an obtuse angle. The second connection part 137 is connected to the first connection part 136 at an obtuse angle and the movable connection part 133 is connected at an obtuse angle. Accordingly, the second connection portion 137 connects the movable member coupling portion 133 and the first connection portion 136 with a stepped connection therebetween.

In addition, the connecting member 130 further includes a reinforcing protrusion 138 for reinforcing the strength.
