Figure 3 is a side view showing the overall configuration of the skate for moving cargo according to the invention.

Referring to FIG. 3, the skate is integrally higher than the skate body 10 at one end of the skate body 10 and the skate body 10 that is long in the longitudinal direction in which a space is provided therein, and a space is provided therein. It includes a skate head 12 formed in the upper and lower openings. Inside the skate body 10, a plurality of lifting rollers 24a and movable rollers 24b are sequentially provided with an operation link 20 mounted thereon. In addition, the cam 30 is pivotally mounted in the skate head 12 via the pivot shaft P1, and one side of the cam 30 is connected to the front end of the operation link 20. Accordingly, the actuating link 20 moves in the longitudinal direction in connection with this by the pivoting operation of the cam 30, thereby lifting the skate body 10 and the skate head 12 from the track surface.

Furthermore, a plurality of protruding cams 14 having inclined portions and flat portions are provided on the upper surface of the skate body 10 at equal intervals. The lifting roller 24a of the operation link 20 is adjacent to the protruding cam 14. Accordingly, when the operation link 20 moves in the longitudinal direction according to the pivoting motion of the cam 30, the lifting roller 24a moves along the inclined portion of the protruding cam 14 to reach the flat portion. Accordingly, the actuating link 20 protrudes below the skate body 20 by the height of the protruding cam 14 so that the movable roller 24b of the actuating link 20 is grounded to the track bottom and the skate body 10. ) And the head 12 are lifted by the height difference.

According to an embodiment of the present invention, the hollow guide cap 16 having an inclined portion and a flat portion is provided at equal intervals on the inner surface of the skate body 10 between the protruding cams 14. The movable pin 26 is installed at equal intervals in the operation link 20 at a position corresponding to the guide cap 16, and the movable pin 26 is located inside the guide cap 16. Accordingly, the actuating link 20 from the skate body 10 is not detached, while the movable pin 26 moves upward along the inner wall of the guide cap 16 when the actuating link 20 is axially operated as described above. Or to move up and down to guide the lifting and lowering of the operation link (20).

Preferably, the outer peripheral surface 160 of the flat portion of the guide cap 16 is located on the same line as the bottom surface 100 of the skate body 10. Accordingly, the guide cap 16 is the skate body 10 in accordance with the axial movement of the operation link 20 while preventing the departure of the operation link 20 via the movable pin 26 located therein. And the lifting height of the skate head 12 can be secured to the maximum.

On the other hand, Figure 4 is an enlarged view of the skate head portion of the skate according to the invention.

Referring to FIG. 4, the present invention further includes a stopper 40 hinged to the other end of the cam 30 pivotably fastened in the skate head 12 through the movable shaft P2. The stopper 40 is normally positioned inside the skate head and protrudes out of the lower end of the skate head 12 according to the pivoting motion of the cam 30. Specifically, the skate head on the rotational track T1 of the movable shaft P2 on the basis of the pivot shaft P1 when the cam 30 is rotated counterclockwise with respect to the pivot shaft P1. 12) The support shaft (P3) is formed on one inner side. Therefore, when the cam 30 is rotated counterclockwise with respect to the pivot axis P1, the skate body and the skate head as described above by the operation of the operation link 20 associated with the pivot motion of the cam 30. Is lifted. At the same time, as shown in (b) of FIG. 4, one side of the stopper 40 is supported by the support shaft P3 and the other side protrudes to the lower end of the skate head 12 to form a safety device.

The safety device by the stopper, when the skate body and the head are lifted and slides in the track by the movable roller, forms a reaction force by foreign matter such as stepped stones or gravel formed higher than the bottom of the track and is supported by the cam while being supported by the support shaft. It serves to return the cam to its original position by transferring the clockwise swing reaction force, which will be described in more detail with reference to the operation of the present invention described below.

The important consideration here is that the protruding distance L1 of the stopper, which protrudes to the skate head bottom by the cam pivot, protrudes to the skate body bottom by the cam pivot and contacts the track bottom. It is to be formed at least short compared to the protrusion distance (L2) of the movable roller. This is because the stopper protruding to the lower part of the skate when the movable roller of the operation link moves in contact with the bottom of the track according to the pivot movement of the cam keeps a gap with the bottom of the track so that the smoothness of the skating is achieved. This is to induce sliding.

Hereinafter will be described in more detail the operation and effect of the present invention configured as described above.

5 is a view showing an operating state according to an embodiment of the present invention, (a) is a side configuration diagram showing the state before the lifting of the skate (b) is a side configuration diagram showing the skate after lifting.

5, the cam 30 is formed with a fastening hole 32 to fasten the operation bar. Accordingly, when the operating bar B is fastened with the fastening hole 32 and the operating bar B is pulled (counterclockwise in the drawing), the pivoting motion of the cam 30 with respect to the pivot axis P1 is pivoted. In connection with the cam 30 and the actuated link 20 is pushed to one side in the longitudinal direction (left to right in the drawing). At the same time, the lifting roller 24a reaches the flat portion while moving along the inclined portion of the protruding cam 14. In addition, the movable pin 26 which is fastened to the actuating link 20 guides the ascending and descending of the actuating link 20 while moving upward or downward along the inner wall of the guide cap 16. Accordingly, the skate body 10 and the head 12 are elevated by the height of the protruding cam 14 while the movable roller 24b is grounded to the bottom of the track as shown in FIG. 5 (b).

In this state, the roller can be slid along the track due to the rolling motion of the movable roller grounded to the floor, thereby carrying the heavy cargo on the skate in place.

Here, the outer peripheral surface 160 of the flat portion of the guide cap 16 is located at least on the same line within the range that does not protrude to the bottom surface 100 of the skate body 10. Accordingly, the guide cap 16 is the skate body 10 in accordance with the axial movement of the operation link 20 while preventing the departure of the operation link 20 via the movable pin 26 located therein. And it is possible to ensure the maximum lifting distance of the skate head 12.

Furthermore, the stopper 40 protrudes below the skate head 12 together with the pivoting motion of the cam 30 to form a safety device. Specifically, when the cam 30 rotates in a counterclockwise direction as described above with the pivot axis P1 as the point, the stopper 40 moves downwards under the skate head 12 as shown in FIG. Extrude At the same time, the connecting portion of the cam 30 and the stopper 40 by the movable shaft P2 is supported by the support shaft P3.

In this state, when an external force due to moving inertia is applied at one end of the stopper 40 as shown in FIG. 6 (see arrow direction) when a skate or gravel formed higher than the track bottom surface is caught during the movement of the skate, the other end of the stopper 40 is stopped. Since it is supported by the support shaft P3, it transfers clockwise swing reaction force to the cam 30 as a base. Accordingly, the cam 30 is returned to the inside of the skate head 12 while rotating the pivot shaft P1 clockwise again to the point due to the swing swing force, and at the same time, the operation link 20 associated with the cam 30 is also used. The skate body 10 and the skate head 12 are lowered and grounded with the track bottom while moving in the opposite direction as described above (left in the drawing; see a broken line) by the height of the protruding cam. Thus, the skate in motion can be stopped momentarily.

Therefore, while the skate head portion being moved is in contact with the step formed at the front end of the track to prevent skewing, the skate head portion can be lowered and the movement can be stopped so that the operation for returning the operation bar to the original position is not required. In addition, even if foreign matters, such as gravel, are stuck inside the track, the foreign material contacts the stopper and brakes by lowering the skates as described above. Therefore, it is not possible to operate the skates forcibly even if the foreign matter is sandwiched between the tracks and the skates. To prevent it.

As described above, according to the inventors of the present invention cargo movement skate, the lifting height of the skate body which is lifted while being grounded to the track by the guide cap and the operating piece can be further improved, and the skate in motion due to the stopper provided in the skate Can be stopped instantaneously to further improve the stability of the device, thereby improving the reliability of the product.

What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, without departing from the gist of the present invention as claimed in the following utility model registration claims. Anyone with ordinary knowledge in the field of the present invention will have the technical spirit of the present invention to the extent that various modifications can be made.
