The slide-type three-stage rail according to the present invention is a device for slidingly moving a movable body, such as a display rack or a drawer with a load, which is relatively heavy and difficult to move by manpower, and a metal block is not directly contacted in the process of moving the movable body. In other words, the movable body can be drawn in and out more smoothly, and the internal configuration is simple, so that it is easy to manufacture and maintain, and has the greatest durability.

The slide-type three-stage rail according to the present invention can be mounted in a vertical direction when mounted in a drawer or the like and placed in a horizontal direction when mounted in a factory floor or the like. In the present invention, a description will be given based on the case where the slide-type three-stage rail is erected and mounted in a vertical direction.

The slide-type three-stage rail according to the present invention is coupled to a fixed body, a fixed block 100 provided with two or more upper fixed rollers and two or more lower fixed rollers, and an upper end contacting the upper fixed roller 110 The lower end is mounted to contact the lower fixed roller 120, the first movable block 200 is slidable in the front-rear direction, the second movable block 300 coupled to the movable body, and the upper end of the upper movable roller 210 And a guide block 400 fixedly coupled to the second moving block 300 so as to be in contact with the lower moving roller 220.

At this time, two or more upper fixed rollers 110 and two or more lower fixed rollers 120 are provided on the side of the fixed block 100 toward the first moving block 200, and the fixed of the first moving block 200 On the opposite side of the block 100, that is, on the side facing the second moving block 300, two or more upper moving rollers 210 and two or more lower moving rollers 220 are provided. Therefore, the first moving block 200 is transferred in the front-rear direction while maintaining contact with only the upper fixed roller 110 and the lower fixed roller 120, but does not directly contact the fixed block 100, and moves secondly. The block 300 is also transferred in the front-rear direction while maintaining contact with only the upper moving roller 210 and the lower moving roller 220, and does not directly contact the first moving block 200.

On the other hand, the fixed block 100 and the first moving block 200 and the second moving block 300 are made of metal so as to have a rigidity of a certain level or higher, and the rollers 110, 120, 210 mentioned above , 220) is made of synthetic resin with a certain level of elasticity to reduce friction, vibration, and noise. Therefore, when the first moving block 200 and the second moving block 300 are transferred to the front and rear, each block 100, 200, 300, 400 made of metal has rollers 110, 120, 210 having elasticity, 220), there is an advantage in that no noise or vibration is generated due to friction between metal members.

Here, the fixed body may mean a specific object or a place such as a floor of a factory or exhibition hall mounted to fix the slide-type three-stage rail, and the movable body means a movable body mounted on the slide-type three-stage rail and slide-moved. can do. For example, when mounted on furniture, the fixture may be a furniture body and a movable body may mean a drawer of furniture, and in the case of an exhibition hall or a factory, the fixture may mean a floor or the top of a specific object. The moving object may mean a heavy object (such as a car or an exhibition) or a display stand for moving the slide.

Specifically, when the three-stage rail is mounted on the furniture, a pair of fixed blocks 100 coupled to the left and right inner walls of a space in which a drawer is drawn in the furniture body, and an upper end contacting the upper fixed roller 110, The first moving block 200 is slidable in the front-rear direction, the second moving block 300 coupled to the left and right outer walls of the drawer, and the upper end moving upwards so that the lower end is mounted to contact the lower fixed roller 120. It may be applied as a guide block 400 that is fixedly coupled to the second moving block 300 so as to contact the roller 210 and the lower end to contact the lower moving roller 220,

When applied to an exhibition hall or a factory, the fixed body is a floor of a specific place, the mobile body is a weight object having a certain weight, the fixed block is coupled to the floor, and the mobile block is on the lower surface of the heavy object. It can have a combined configuration.

The slide-type three-stage rail according to the present invention has an advantage that blocks are not moved up and down in the process of moving the moving body, since blocks moving during the movement of the moving body are configured to slide between rollers arranged up and down. In this case, the two or more lower fixed rollers 120 are the two or more upper fixed rollers 110 so that the rollers arranged up and down can stably hold the upper and lower ends of the first moving block 200 and the guide block 400. It is preferred that each of the two or more lower moving rollers 220 is located in the vertically lower position, and the two or more lower moving rollers 210 are disposed in the vertical lower direction of each of the two or more upper moving rollers 210.

Meanwhile, if the contact area between the upper end of the first moving block 200 and the upper fixed roller 110 and the contact area between the lower end of the first moving block 200 and the lower fixed roller 120 increase, the fixed roller ( Since the rolling friction of 110 and 120) increases, the frictional force when moving the moving object increases. Likewise, even when the contact area between the upper end of the guide block 400 and the upper moving roller 210 and the contact area between the lower end of the guide block 400 and the lower moving roller 220 are wide, the moving rollers 210 and 220 There is a problem that the rolling friction increases, and it takes a large force to move the moving object.

In order to solve the above problems, the slide-type three-stage rail according to the present invention has an arc shape in which a cross section of a portion in contact with the upper fixed roller 110 is convex upward on the upper end of the first moving block 200. A first upper rail 202 having a first lower rail 204 having a circular arc shape in which a cross section of a portion in contact with the lower fixed roller 120 is convex downward at a lower end of the first moving block 200. ) Is preferably provided. Likewise, at the upper end of the guide block 400, a second upper rail 402 having a circular arc shape with a convex upward cross-section of the portion in contact with the upper moving roller 210 is provided, and the guide block 400 At the lower end, it is preferable that the second lower rail 404 has a circular arc shape with a convex downward cross section of the portion in contact with the lower moving roller 220.

In the slide-type three-stage rail according to the present invention, the outer circumferential surfaces of the rollers 110, 120, 210, and 220 may be concave to solve this problem. That is, the upper fixed roller 110 has a concave surface in contact with the first upper rail 202, and the lower fixed roller 120 has a concave surface in contact with the first lower rail 204. The upper moving roller 210 has a surface in contact with the second upper rail 402 is concave, and the lower moving roller 220 is in contact with the second lower rail 404 It can be formed concavely.

When the outer circumferential surfaces of the respective rollers 110, 120, 210, and 220 are concave, the rails 202, 204, 402, even if an external force is applied to the moving body in the process of sliding the moving object by the user, Since the 404s do not deviate from the outer circumferential surfaces of the respective rollers 110, 120, 210, 220, it is possible to effectively prevent the problem of the moving body shaking in the width direction.

The slide-type three-stage rail according to the present invention is provided with a plurality of stoppers to limit the withdrawal and withdrawal distances of the first moving block 200 and the second moving block 300.

In other words, the upper fixed roller 110 and the lower fixed roller 120 that extend in the vertical direction from the front end of the first moving block 200 and are located at the front when the first moving block 200 moves as far back as possible. ) Is provided with a pair of first front stoppers 230 that are respectively in contact with each other, and extend in the vertical direction from the rear end of the first moving block 200 to move the first moving block 200 forward as much as possible.
