Abstract

A multi joint slider device may include a center slider arranged at a center in a length direction thereof, the center slider having at least one roller, a front slider arranged in front of the center slider connected thereto with a first joint to enable relative rotation, the front slider having at least one roller, and a rear slider arranged in rear of the center slider connected thereto with a second joint to enable relative rotation, the rear slider having at least one roller, thereby permitting smooth rolling and sliding on the rail having a curved portion.

First claim

What is claimed is:

1. A multi joint slider device comprising:
a center slider arranged at a center in a length direction thereof, the center slider having at least one roller;
a front slider arranged in front of the center slider connected to the front slider with a first joint to enable relative rotation therebetween, the front slider having at least one roller;
a rear slider arranged in rear of the center slider connected to the rear slider with a second joint to enable relative rotation therebetween, the rear slider having at least one roller; and
a rail having a center rail arranged at middle in a height direction thereof, an upper side rail arranged over the center rail in the height direction, and a lower side rail arranged under the center rail in the height direction,
wherein the center slider, the front slider, and the rear slider are slidably engaged to the rail.

2. The multi joint slider device of claim 1 , wherein the center rail, the upper side rail and the lower side rail are formed as one unit.

3. The multi joint slider device of claim 2 , wherein the center rail, the upper side rail and the lower side rail have a channel-shaped cross sections continuous in the length direction thereof, respectively.

4. The multi joint slider device of claim 3 ,
wherein the center rail has an opening to which openings of the upper side rail, and the lower side rail are arranged perpendicular, and
wherein the openings of the upper side rail and the lower side rail are formed to face each other.

5. The multi joint slider device of claim 1 , wherein the rail has a curved portion with a curve at a predetermined portion thereof in the length direction.

6. The multi joint slider device of claim 1 , wherein the center slider includes;
a center slider body,
two upper side rail rollers rotatably coupled to an upper side of the center slider body to be inserted in the upper side rail for rolling, and
two lower side rail rollers rotatably coupled to a lower side of the center slider body to be inserted in the lower side rail for rolling.

7. The multi joint slider device of claim 6 , wherein the center slider body includes;
a support wall portion formed extendedly vertically in an up and down direction;
an upper flange formed bent and extended from an upper edge of the support wall portion perpendicular thereto; and
a lower flange formed bent and extended from a lower edge of the support wall portion perpendicular thereto,
wherein two first assembly holes are formed in an upper side of the support wall portion along a longitudinal direction of the multi joint slider device at a predetermined distance, to mount the two upper side rail rollers thereto rotatably, and
wherein two first assembly holes are formed in a lower side of the support wall portion along the longitudinal direction of the multi joint slider device at a predetermined distance, to mount the two lower side rail rollers thereto, rotatably.

8. The multi joint slider device of claim 7 , wherein one end of an arm having a sliding component mounted thereto is inserted between the upper flange and the lower flange and rotatably secured with an assembly pin.

9. The multi joint slider device of claim 8 ,
wherein the support wall portion has assembly flanges formed on both sides of the upper side and the lower side projected in the longitudinal direction of the multi joint slider device, respectively,
wherein the front slider includes a front slider body that has an assembly flange formed on a rear side thereof,
wherein the rear slider includes a rear slider body that has an assembly flange formed on a front side thereof,
wherein the assembly flange of the front slider body is inserted between the two upper and lower assembly flanges of the center slider body, and secured with a first assembly pin to form the first joint, and
wherein the assembly flange of the rear slider body is inserted between the upper and lower assembly flanges of the center slider body, and secured with a second assembly pin to form the second joint.

10. The multi joint slider device of claim 9 ,
wherein the front slider body has a first assembly boss formed on one side thereof as one unit therewith projected to a side direction, and
wherein a center rail roller is inserted into the first assembly boss to be rotatably mounted.

11. The multi joint slider device of claim 10 ,
wherein a second assembly boss is formed adjacent to the first assembly boss as one unit therewith projected upward,
wherein an upper side rail support roller is rotatably assembled to an upper side of the second assembly boss to be inserted in the upper side rail and supported thereby, and
wherein a lower rail support roller is rotatably assembled to a lower side of the second assembly boss to be inserted in the lower side rail and supported thereby.

12. The multi joint slider device of claim 9 ,
wherein the rear slider body has a first assembly boss formed on one side thereof as one unit therewith projected in a side direction, and
wherein a center rail roller is rotatably mounted to the first assembly boss for inserting in the center rail for rolling.

13. The multi joint slider device of claim 12 ,
wherein a substantially “T” shaped assembly groove is formed in a portion adjacent to the first assembly boss in a vertical direction,
wherein a plurality of fastening holes are formed in a bottom of the assembly groove in communication therewith,
wherein an adjuster block is inserted in the assembly groove and fastened through the fastening holes, and
wherein an adjuster roller is assembled to, and rotatably supported by the adjuster block for being in contact with an upper side of the upper side rail to support the upper side rail.

14. The multi joint slider device of claim 13 ,
wherein the rear slider body has a second assembly boss formed on a rear side thereof extended vertically,
wherein an upper side rail support roller is rotatably assembled to the upper side of the second assembly boss for being inserted in the upper side rail for rolling, and
wherein a lower side rail support roller is rotatably assembled to the lower side of the second assembly boss for being inserted in the lower side rail for rolling.
