It is preferable that the fixing plate 350 fixed by the fixing plate assembly hole of the leaf spring and the bolt is fixed to the pedestal 360 and the bolt again. The pedestal 360 and the fixing plate 350 may be configured in one piece, but the reason for being fixed with the bolts is to facilitate the detachment in order to enable the pedestal 360 to be used for various purposes.

12 is a partial section view illustrating the coupling process of the leaf spring and the guide roller and the peripheral elements in the lifter using the leaf spring according to the preferred embodiment of the present invention.

 As shown in Figure 12

Three leaf springs 100 are provided, each positioned at 120 degrees. Then, the projections and grooves of each leaf spring face each other at a position of 120 degrees in the longitudinal direction. The leaf spring is rolled in a round shape by a leaf spring winder at the lower portion of each leaf spring, The leaf spring is raised or lowered by the worm gear groove 170 by the rotation. At this time, while the guide roller 340 is pressing the leaf spring to be raised or lowered by the worm gear, the protrusion and the groove of the leaf spring are combined and dismantled. The protrusions and the grooves are smoothly combined, which causes the leaf springs to change from horizontal to vertical or from vertical to horizontal to form a triangular prism or disappear .

On the other hand, when each leaf spring forms a column shape by the worm gear and guide roller, the leaf spring is unrolled or dried at the lower end of the leaf spring, which induces the direction in which the leaf spring is released or dried, and the leaf spring is minimal. It is preferable to install the leaf spring guide roller 410 to be maintained in the space, which is preferable to occupy as little space as possible without limiting the leaf spring or damage to the spring characteristics due to the nature of the leaf spring. . The method can be configured in many ways.

In addition, it is preferable that two or more guide rollers are provided for each leaf spring, and the position of the guide roller is preferably located in the middle of the worm gear. The reason for this is to assist the transverse load (lateral load) of the entire triangular prism when the leaf spring is partially or entirely triangular in shape, and the protrusions and grooves of the leaf spring are always It is intended to help combine in position. That is, the leaf spring is primarily supported in the vertical direction by the gear groove of the worm gear, and is supported by the guide roller in the horizontal direction. In addition, the guide roller 340, the leaf spring guide roller 410, etc. It is preferable to install a bearing 412, etc. at both ends in order to maximize the performance of each,

The leaf spring winder 400 is preferably composed of the leaf spring guide roller 410, guide roller 340, bearing 412, support 414.

As you can see from the main road,

The maximum height in the vertical direction of the lifter using the leaf spring may rise in the vertical direction at the same height as the number of turns (the number of turns) wound on the leaf spring winder 400.

When the leaf spring is lowered in the vertical direction by the rotation of the worm gear 320, the leaf spring 100 passing through the guide roller 340 is wound by the leaf spring guide roller 410 without causing the leaf spring to deviate from the track. At this time, the leaf spring guide roller 410 is not subjected to the load in the vertical direction received from the column-shaped leaf spring, and because only the role of inducing the leaf spring to be wound well, it is safe to use a round bar to reduce the installation space. It is preferable that both edges of the leaf spring guide roller form a jaw so that the leaf spring does not depart from the track. In addition, even though the leaf spring wound on the leaf spring winder almost comes out as a triangular prism, the minimum number of turns wound on the leaf spring winder is preferably wound two or more times, which is caused by the leaf spring guide roller. It's the minimum winding to be aligned. In addition, the winding end of the leaf spring is treated with a round shape of the clock-like shape of the clock, it is preferable to reduce the friction between the leaf springs when the leaf spring is wound.

In addition, it is preferable to install bearings 412 at both edges of the guide roller 340 and the leaf spring guide roller 410 so that the leaf spring is smoothly wound when the leaf spring is wound or released by the leaf spring winder. This makes it possible to smooth the movement of the leaf spring and to suppress the noise at the same time as the leaf spring moves up and down.

The leaf spring winder 400 as described above is preferably installed by the support 414 as shown in Figure 14, the support may be configured in various shapes.

15 is an explanatory diagram showing the operation of the driving unit 300 and the power transmission unit 310 according to an embodiment of the present invention.

As shown in this figure, the drive unit binds the spindle portion of the drive unit 300 in the vertical direction to the bottom plate 200 on the upper side of the bottom plate 200 so that the spindle of the drive unit is located in the bottom direction of the bottom plate 200. desirable. This is to make full use of the space remaining naturally in the horizontal direction in the installation space of the leaf spring winder, and since the head of the drive unit is attached toward the bottom of the base plate 200, it minimizes the appearance height of the lifter and provides stable power transmission. This is to be arranged to reduce the size by minimizing the outer size of the lifter.

In addition, the power transmission unit 310 between the drive unit 300 and the worm gear 320 is preferably used timing timing to prevent the generation of maneuverability, noise, etc., but it may be safe to use a chain, a V-belt or the like depending on the use environment.
