DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a door checker of a vehicle to which a rolling motion and a sliding motion according to the present invention are applied will be described in detail with reference to the accompanying drawings.

A door checker of a vehicle to which a rolling motion and a sliding motion according to the present invention is applied includes a checker arm (10) having one side connected to a vehicle body and having a plurality of convex portions (11) and a concave portion (12) alternately formed, The door checker includes a roller (23) installed to be elastically supported on the checker arm (10) and rolling on the checker arm (10), the roller (23) being rotatably installed inside the door checker A carrier 22 which is installed so as to be resiliently supported by the arms so as to be respectively disposed on the upper and lower portions of the checker arm 10 and a roller 22 which is rotatably supported by the roller 23 while the roller 23 passes through the recess 12 The roller 23 and the concave portion 12 are spaced apart from each other without contacting the checker arm 10 and the slide 22 is slid in a state in which the carrier 22 and the checker arm 10 are in contact with each other, Means.

A checker arm 10 is provided on the vehicle body side and a carrier 22 is provided on the door side and a roller 23 is provided inside the carrier 22 to rotate in close contact with the checker arm 10.

One end of the checker arm 10 is fastened to the vehicle body at one end, and the plurality of protrusions 11 and the recesses 12 are alternately formed.

The convex portion 11 and the concave portion 12 may be formed in the entire section of the checker arm 10 but may be formed in a certain section so as to be relatively movable with respect to the roller 23 when the door is opened to some extent May be formed. That is, the convex portion 11 and the concave portion 12 may not be formed in the portion of the checker arm 10 adjacent to the vehicle body, but may be formed in the remaining portion.

The number of the stages at which the door can be temporarily stopped when the door is opened may be set according to the number of the convex portion 11 and the concave portion 12 formed. For example, if the concave portions 12 are formed in three, the door can be set in three stages until the door is opened to the maximum.

The carrier 22 is installed in an elastically supported state inside the housing 21 formed on the door and is disposed on the upper and lower portions of the checker arm 10, respectively.

A spring 24 is provided between the carrier 22 and the housing 21 to elastically support the carrier 22 toward the checker arm 10.

In addition, rollers 23 that rotate in contact with the checker arm 10 are provided inside the carrier 22, respectively. Since the carrier 22 is elastically supported by the spring 24, the carrier 22 and the roller 23 are elastically supported by the spring 24 integrally. The roller (23) rotates relative to the checker arm (10) when the door is opened, thereby giving a sense of relief when the door is opened.

The present invention prevents the roller 23 from contacting the checker arm 10 while the roller 23 passes through the recess 12 and prevents the contact between the carrier 22 and the checker arm 10 10 are brought into direct contact and friction with each other.

The slip means may be a protrusion 13 formed on the checker arm 10 and a contact surface 22a formed on the carrier 22.

The projecting portion 13 is formed on the side surface of the checker arm 10. The protruding portions 13 are preferably formed on both side surfaces of the checker arm 10. The protrusion 13 is formed in a predetermined length only in a section where the recess 12 is formed in the checker arm 10 and the height of the protrusion 13 along the longitudinal direction of the checker arm 10 .

A contact surface 22a is formed in the carrier 22 and is formed to abut the projection 13 while the roller 23 passes through the recess 12. The contact surface 22a is formed at an end of a portion extending from the side surface of the carrier 22 toward the upper surface or the lower surface of the protrusion 13. [ That is, in the carrier 22 disposed on the checker arm 10, the contact surface 22a is formed at an end of a portion extending downward toward the upper surface of the protrusion 13, and the checker arm 10 The contact surface 22a is formed at an end portion of the carrier 22 extending upward toward the lower surface of the protrusion 13. [

The interval between the contact surfaces 22a of the carrier 22 disposed at the upper portion and the lower portion of the checker arm 10 is minimized while the roller 23 passes through the concave portion 12, Is the same as the height of the projecting portion 13.

The distance between the contact surfaces 22a is narrower than the distance between the rollers 23 in the carrier 22 disposed at the top and bottom of the checker arm 10. [

In addition, the inner surface of the carrier 22 on which the contact surface 22a is formed may contact both side surfaces of the checker arm 10 to prevent the carrier 22 from flowing to the left and right. Accordingly, a separate guide for preventing lateral movement of the checker arm 10 becomes unnecessary.

The operation of the door checker of the vehicle to which the rolling motion and the sliding motion according to the present invention having the above-described configuration are applied will be described.

Fig. 10 shows the operation of the door checker of a vehicle to which the rolling motion and the sliding motion according to the present invention are applied.

10 (a), the roller 23 is located in the convex portion 11, so that the roller 23 and the checker arm 10 contact each other to cause the roller 23 to roll.

10 (b), the roller 23 is positioned between the convex portion 11 and the concave portion 12, and when the door is opened (in the direction indicated by the black arrow) The roller 23 performs rolling motion.

As the opening of the door further proceeds, the roller 23 is positioned in the recess 12, as shown in Fig. 10 (c). At this time, the roller (23) is prevented from being in direct contact with the checker arm (10) by the sliding means. That is, the contact surface 22a contacts the upper surface and the lower surface of the protrusion 13, respectively, so that the carrier 22 and the checker arm 10 slide in place of the rolling motion.

(See (d) of FIG. 10) while the roller 23 passes through the concave portion, the sliding movement is performed instead of the rolling motion, and since the carrier 22 is elastically supported by the spring 24, So that the door is prevented from being swayed. That is, since the rolling motion of the roller 23 is eliminated, the roller 23 is positioned in the concave portion 12, so that occurrence of the swaying will not occur.

10 (e), the roller 23 passes through the concave portion 12 and comes into contact with the checker arm 10 again to start rolling motion, and as shown in FIG. 10 (f), and is positioned at the top of the convex portion 11 of the next stage.

The roller 23 and the carrier 22 are alternately brought into contact with the checker arm 10 during the opening of the door so that the rolling motion and the sliding motion are alternately performed, It is possible to prevent stumbling.

In addition, while the door is closed, the door is prevented from being swayed by the same principle.
