Accordingly, the holder (S) can be moved in a stable sense.

Even when the cradle S is slid upwards as opposed to the downward movement force of the cradle S as described above, the mobile unit 20 is moved upward by the first and second bearings 21 and 22. In conjunction with the smooth movement, one side 31a of the elastic body 31 is guided in the helical direction by the guide groove 33 of the deceleration pulley 32, so that the moment torque is constantly reduced or kept constant. Accordingly, the upward movement of the holder (S) can also be made stable.

On the other hand, as shown in Figure 3, the other side 31b of the elastic body 31 is preferably provided with a tension control lever 34 for adjusting the tension of the elastic body 31. The tension control lever 34 is provided on the outside of the body unit 10 so as to adjust the tension in conjunction with the load of the predetermined article mounted on the holder (S) is operated by the operator. At this time, when adjusting the tension of the elastic body 31 by the tension control lever 34, the load display portion 34a for displaying the load to the outside of the body unit 10 for the convenience of the operator to the body unit 10 It is good to be prepared.

The tension control lever 34 is connected to the other side 31b of the elastic body 31 using the timing belt 35 as shown in FIG. 3, or the elastic body (34) through the bevel gear 36 as shown in FIG. 4. 31 may be connected to the other side 31b. In addition, as shown in FIG. 5, a modification in which the tension control lever 34 is directly connected to the other side 31b of the elastic body 31 is possible.

Referring to Figure 6, the cradle support device 100 according to another embodiment of the present invention is shown. The cradle support device 100 according to another embodiment of the present invention is similar to the cradle support device 1 according to the embodiment described with reference to FIGS. 1 to 5, the body unit 10, the mobile unit 20, and Control unit 130 is included. Here, according to another embodiment of the present invention, in that the control unit 130 includes the first and second elastic bodies 131, 132, flat pulley 133 and helical pulley 134, It differs from one embodiment. That is, the body unit 10 and the mobile unit 20 has the same configuration in one embodiment. Accordingly, detailed configurations of the body unit 10 and the mobile unit 20 are similar to those of the exemplary embodiment described with reference to FIGS. 1 to 5, and thus, detailed descriptions thereof will be omitted. In addition, as the mobile unit 20 moves in a state of supporting the holder S, the mobile unit 20 and the holder S are displayed together in the FIGS. 6 and 7.

The first elastic body 131 is connected to the mobile unit 20 and one side (131a), the other side (131b) is a tension spring fixed to the body unit (10). Similarly, the second elastic body 132 also has one side 132a is connected to the mobile unit 20, the other side 132b is a tension spring is connected to the body unit 10. The first and second elastic bodies 131 and 132 are arranged side by side parallel to each other, the elastic force is variable by the movement of the mobile unit 20 is connected to the cradle (S).

The flat pulley 133 and the helical pulley 134 are provided in parallel between one side 131a and 132a of the first and second elastic bodies 131 and 132 and the mobile unit 20, respectively, and rotate in both directions. do. At this time, the flat pulley 133 is provided as a general pulley, the helical pulley 134, like the deceleration pulley 32 described in one embodiment, based on the central axis 134a in conjunction with the movement of the cradle (S). One side 132a of the second elastic body 132 is moved forward or backward in the spiral direction. Accordingly, the helical pulley 134 is also provided with a guide groove 135 for guiding one side 132a of the second elastic body 132 in a spiral direction.

In addition, the other side (131b) of the first elastic body 131 is connected to the tension control lever 136 provided on the outside of the body unit 10 so that the tension is adjusted in conjunction with the load of the article mounted on the cradle. . The tension control lever 136 is a load indicating the load mounted on the cradle to the outside of the body unit in conjunction with the adjustment by the tension control lever 136 as in the embodiment described above with reference to FIG. The display unit 34a may be provided. In addition, although not shown in detail, the tension control lever 136 according to another embodiment also, as shown in FIGS. 3 to 5, the other side 131b and the timing belt 35 or bevel of the first elastic body 131. It may be connected via gear 36 or may be directly connected.

Cradle support device 100 according to another embodiment of the present invention having the configuration as described above, as shown in Figure 7, in conjunction with the mobile unit 20 connected to the cradle (S) is lowered in the downward direction, The first and second elastic bodies 131 and 132 extend in the longitudinal direction. As a result, even if the force applied to the mobile unit 20 to move the cradle S is increased, the first and second elastic bodies 131 and 132, the flat pulley 133, and the helical pulley of the parallel structure are increased. The mobile unit 20 can be moved in a stable manner by (133) (134). At this time, when the downward movement of the mobile unit 20 in the flat pulley 133, the moment torque is constantly increased as the first elastic body 131 is increased, the helical pulley 134, which is a deceleration pulley, has a constant moment torque Is reduced. Here, the increase force applied to the flat pulley 133 and the decrease force applied to the helical pulley 134 are in equilibrium with each other.

More specifically, as shown in FIG. 6, when the repulsive force applied to the first and helical pulleys 133 and 134 at the starting point of the mobile unit 20 is 5 kg and 10 kg, respectively, the sum of the repulsive force is 15 kg. As shown in FIG. 7, the repulsive force applied to the first and helical pulleys 133 and 134 in the lowered state of the mobile unit 20 is 10 kg and 5 kg, respectively, and the sum of the repulsive force is 15 kg. That is, as the mobile unit 20 descends, the flat pulley 133 increases the repulsive force by 5 kg, and the repulsive force of the helical pulley 134 decreases by 5 kg.

For reference, in contrast to FIG. 7, even when the mobile unit 20 connected to the holder S is elevated upwards, the first and second elastic bodies 131 and 132 and the flat pulley 133 and the parallel structure are provided. The helical pulleys 133 and 134 can move the mobile unit 20 with a sense of stability. At this time, when the upward movement of the mobile unit 20 in the flat pulley 133, the moment torque is constantly reduced as the first elastic body 131 is compressed, and the helical pulley 134, which is a deceleration pulley, has a constant moment torque Is increased. Here, the reduction force applied to the flat pulley 133 and the increase force applied to the helical pulley 134 are in equilibrium with each other.

On the other hand, the position where the flat pulley 133 and the helical pulley 134 is installed in the body unit 10 is not limited to the illustration of Figs. That is, as shown in FIG. 8, the flat pulley 133 ′ and the helical pulley 134 ′ are arranged side by side under the body unit 10, and connected to the first and second elastic bodies 131 ′ and 132. ') Is also possible to the embodiment is disposed on the side of the body unit 10 so that the installation direction is guided by the plurality of rollers (R) to face the holder (S). At this time, the pair of connecting members 140 connected to the flat pulley 133 'and the helical pulley 134' is connected to the cradle S, thereby providing a controlled moving force. For reference, the connecting member 140 is also guided in the installation direction by the roller (R).

In addition, the flat pulley 133 ′ and the helical pulley 134 ′ may be connected to each other by one rotation shaft 137 and rotated as shown in FIG. 9. In addition, as shown in FIG. 10, another modification is possible in which the flat pulley 133 ″ and the helical pulley 134 ″ are formed in one body. In this case, the flat pulley 133 "and the helical pulley 134" are formed in one body, and are connected to the cradle S by using one connection member 140 '.
