The operation of the first embodiment of the mobile pallet described above will now be described.

Figure 3 is a front sectional view showing a coupling structure of the mobile pallet of the present invention, Figure 4 is a functional sectional view showing the action of the mobile pallet of the present invention.

First, FIG. 3 illustrates a state in which the stopper 140 is released, and as shown in the drawing, in a state in which the ball caster 130 is fixed to the lower plate 122 of the connection member 120, the connection member. The pressing plate 143 of the stopper 140 is disposed above the lower plate 122 of the 120, and the support plate 141 is disposed below the lower plate 122.

The pressing plate 143 and the support plate 141 of the stopper 140 are fixed by a connecting bar 144 passing through the through hole 124 of the lower plate 122, and the length of the connecting bar 144 is lower. Since it is set longer than the thickness of 122, the stopper 140 will be in the state which can be raised and lowered on the lower board 122. As shown in FIG.

At this time, the elastic member 125 is disposed in the seating groove formed on the upper inner circumferential surface of the through hole 124. Since the elastic member 125 is elastically supporting the pressing plate 143 in the upward direction while the lower end is supported on the lower plate 122 side and the upper end is supported on the pressing plate 143, the lever 150 is In the state of rotation in the unlocking direction, the stopper 140 moves upward and is spaced apart from the bottom surface.

As described above, the stopper 140 installed on the lower plate 122 in a liftable manner is provided at the center of the support plate 141 in a state in which the support plate 141 contacts the bottom surface in a state of moving downward. The ball of the ball caster 130 protrudes through the through hole 142 to be in contact with the bottom surface. Therefore, it becomes possible to make the ball caster 130 selectively contact the bottom surface as the stopper 140 moves up and down.

That is, as shown in the figure, the lever 150 disposed between the upper plate 121 of the connecting member 120 and the pressing plate 143, the rotating portion 151 is rotatable to the bottom surface of the upper plate 121. In the installed state, the eccentric pressure cam 152 provided on one side of the rotating part 151 is provided to selectively press the pressing plate 143 in the fixed direction, and in the state of lifting the handle 153 in the upward direction The pressing force of the pressure cam 152 is released.

Subsequently, in the state where the pressing force against the stopper 140 is released, the stopper 140 moves upward by the elastic force of the elastic member 125, and in this process, the ball caster 130 installed on the lower plate 122 is moved. Since it is exposed through the through hole 142 of the support plate 141 to be in contact with the bottom surface, the pallet can be moved smoothly, which improves the convenience of movement.

On the other hand, if you want to limit the movement of the pallet, as shown in Figure 4, when moving the knob 153 of the lever 150 to the downward direction, the lever 150 is rotated about the pivot 151, the eccentric The pressure cam 152 presses the support plate 141 of the stopper 140 located above the lower plate 122 in the fixed direction.

At this time, since the support plate 141 is connected to the support plate 141 disposed below the lower plate 122 through the connection bar 144, the support plate 141 is lowered together with the pressure plate 143. In the state in which the lever 150 is completely pressed in the fixed direction, the support plate 141 contacts the bottom surface to limit the rolling motion of the ball caster 130.

On the other hand, the pressing cam 152, the critical point for the fixing is located in the area between the fixed position and the release position of the lever 150, it is prevented that the lever 150 is arbitrarily switched to the fixed or unlocking side.

Meanwhile, in the present embodiment, for example, the elastic member 125 is in the form of a coil spring that surrounds the outer circumferential surface of the connecting bar 144, but the lower plate 122 and the pressing plate 143 of the connecting member 120 are described. It will also be possible to apply a leaf spring for elastically supporting the stopper 140 in the release direction.

The scope of the present invention is not limited to the above-described embodiment, but may be embodied in various forms of embodiments within the scope of the appended claims. Without departing from the gist of the invention claimed in the claims, it is intended that any person skilled in the art to which the present invention pertains falls within the scope of the claims described in the present invention to various extents which can be modified.
