Device for locking cross bar of roof carrier for vehicle}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle roof carrier, and more particularly, to a vehicle cross carrier locking device for a vehicle roof carrier having a structure capable of maximizing the amount of movement of the cable while reducing the rotation radius of the member required for the movement of the locking pin for locking the cross bar on the rail. It is about.

In general, a roof carrier is mounted on an upper part of a roof panel of a vehicle in order to solve the inconvenience of storing a luggage or an object due to a narrow space of a vehicle interior space. Allow other cargoes to be loaded.

The roof carrier having this function includes rails installed in the longitudinal direction of the vehicle on both sides of the roof panel, and two cross bars locked to both rails across the roof panel. By sliding this crossbar along the rail, the user can adjust the distance between the crossbars according to the size of the cargo.

The structure and function of the loop carrier will be described with reference to FIG.

The roof carrier 10 is mounted on the roof panel P of the vehicle. The roof carrier 10 is provided between the pair of rails 21 and 22 and the rails 21 and 22 that are respectively installed in the first direction (that is, the longitudinal direction of the vehicle) on both sides of the roof panel P of the vehicle. It includes two cross bars 11, 12 disposed perpendicular to the rail and both ends of which are movably coupled to both rails 21, 22, respectively.

The cross bars 11 and 12 are slid along the size of the cargo on both rails 21 and 22, so that the spacing between the cross bars 11 and 12 is adjusted. In order to lock the moved cross bars 11 and 12 to the rails 21 and 22, a locking device is mounted at the end of each cross bar 11 and 12.

FIG. 2 is a perspective view showing a general locking device mounted on each cross bar (eg, 11), and for convenience the cross bar is not shown. Meanwhile, as shown in FIG. 2, the locking device includes first and second locking modules 100 and 200 which are respectively installed in both ends of the cross bar 11, but in the following description, first locking. Only the configuration of the module 200 will be described by way of example.

The first locking module 100 rotates (rotates) the base 110 fixed in the housing (not shown) fixed to the tip of the cross bar (11 in FIG. 1), both vertical posts 112 of the base 110. ) The rotatable member 120, the locking pin assembly 130 installed in the rotatable member 120 so as to be horizontally movable, and the cable 300 wound around the locking pin assembly 130.

Meanwhile, the locking pin assembly 130 includes a horizontal guide rod 133 fixed to the rear end of the base 110 and a pulley receiving member through which one end of the guide rod 133 penetrates and moves along the guide rod 133. 135, a pulley 132 rotatably mounted in the pulley receiving member 135 and a horizontal locking pin 131 fixed to the tip of the pulley receiving member 135.

The cable 300 described above is fixed to the lower end of the rotating member 120 in the state wound around the pulley (132). In addition, the other end of the cable 300 is wound on the locking pin assembly of the second locking module 200 symmetrically mounted to the other end of the cross bar 11, the end of which is the lower end of the rotating member. Is fixed to.

In order to move the cross bar (eg, 11) having the locking device of this structure along the rails 21, 22, a first locking module (not shown) is first mounted on one end of the cross bar 11. The rotating member 120 is rotated (in the direction of the arrow in FIG. 2) by using a lever (not shown, but fixed to the top of the rotating member 120) of 100.

As the rotation member 120 rotates, the cable 300 is pulled, and the pulley 132 and the pulley receiving member 135 of the locking pin assembly 130 on which the cable 300 is wound are horizontal guide rods 133. Retreat along. In this process, the locking pin 131 constituting the locking pin assembly 130 is separated from the opening of the corresponding rail (eg, 21 in FIG. 1).

At this time, the spring 134 located in the guide rod 133 is compressed between the pulley receiving member 135 and the inner surface of the base 110.

Meanwhile, while the cable 300 is pulled, the locking pin of the second locking module 200 mounted on the other end of the cross bar 11 also retracts to correspond to another rail (for example, FIG. 1). 22) Depart from the opening.

In this way, the locking pins 131 of the locking modules 100 and 200 mounted at both ends of the cross bar 11 are separated from the openings of the corresponding rails 21 and 22 so that the user can move the cross bar to the rails 21, 22. You can move along 22).

On the other hand, if the locking pin 131 of the locking module 100 corresponds to another opening of the rail 21, the pulley receiving member is provided by the restoring force of the compressed spring 134, which is mounted on the outer circumferential surface of the guide rod 133. 135 moves toward the rail 21, so that the locking pin 131 is inserted into the opening formed in the rail 21. As a result, both ends of the cross bar 11 are fixed to the rails 21 and 22.

The cross bar locking device having such a structure and function has the following problems.

The rotating member 120 rotatably installed on the base 110 to pull the cable 300 includes a horizontal lower member 121 having a predetermined length, and at the tip of the lower member 121, the cable ( The end of 300 is fixed.

The moving length of the locking pin 131 is proportional to the length of the lower member 121, so that the rotating member is sufficiently moved to sufficiently move the locking pin 131 of the first module 100 and the second locking module 200. The horizontal lower member 121 of 120 should have a sufficient length.

When the rotating member 120 is rotated through a lever (not shown) fixed to the upper end of the rotating member 120, the rotation radius of the lower member 121 having a long length is large, and thus, the rotating member ( The lower portion of the 120 should be provided with sufficient space for the rotation of the lower member 121.

Due to the size of the rotating member 120, the diameter of the housing (which is fixed to the cross bars 11 and 12) on which the locking modules 100 and 200 are mounted is increased. On the other hand, instead of increasing the diameter of the housing, an opening of a predetermined area can be formed in the lower portion of the housing, so that the lower member 121 of the rotating member 120 is not affected by rotation by this opening. However, in such a structure, a separate cover member must be mounted to protect the rotating member 120 exposed to the outside through the opening.

Accordingly, the present invention has been made in order to solve the problems occurring in the locking device for locking the cross bar of the loop carrier to the rail as described above, while reducing the size of the locking module to secure the stroke of the member for moving the cable cable And a cross bar locking device capable of sufficiently moving the locking pin to which the cable is fixed.

And a lever, an upper pulley and a lower pulley extending at a height difference between the two support pieces and the support pieces rotatably installed in the frame of the locking pin assembly extending from one end of the lever.

Here, both ends of the cable are fixed to the locking pins of the frame front end of each locking pin assembly in contact with the upper surface of the upper pulley and the lower pulley of each locking module to rotate the lever and the support piece of the rotating member. Both pulleys pull both ends of the cable in opposite directions to move the frame of the locking pin assembly of each locking module in the opposite direction to release the locking pins from the openings of the rail and compress the compression springs.

On the other hand, the cross-bar locking device according to the present invention is fixed to both ends of the cross bar, and further includes a housing in which each locking module is mounted therein, the opening is formed in the housing for the rotation of the lever.

Two locking pins can be separated from the opening of each rail.

In this way, since two end portions of the cable are moved by the two pulleys, the length of the extension piece of the rotating member provided with the pulley can be minimized.

In addition, it is possible to minimize the diameter of the housing in which the locking module is mounted, that is, the thickness (height) of both ends of the cross bars, by the extension piece and the pulley of such a structure, and it is not necessary to install the openings in the housing and the cross bar.

It is preferable to install toward the (), wherein the cable 800 is in contact with the upper surface of the upper pulley (413-1) and the lower surface of the lower pulley (413-2).

The function of the cross bar locking device according to the present invention composed of the above members will be described with reference to FIGS. 3, 4 and 5A and 5B.

FIG. 5A is a cross-sectional view of a cross bar equipped with a locking device composed of a first module and a second module having the structure shown in FIGS. 3 and 4, and the housing 900 fixed to both ends of the cross bar 700. The state in which the first and second locking modules 400 and 500 are mounted in the inside is shown.

In addition, in FIG. 5A, the locking pins 424 of the first and second locking modules 400 and 500 are inserted into the openings formed in the respective rails 601 and 602, that is, the cross bars 700 have both rails ( The locked state at 601 and 602 is shown.

When attempting to move the cross bar 700 along both rails 601, 602, the user corresponds to the lever 411 of the rotating member 410 constituting either locking module (eg 400). It is pulled toward the rail 601, ie in the direction of the arrow shown in FIG. 5A. At this time, the opening 901 is formed in the upper end of the housing 900, the lever 411 can be smoothly rotated.

As the lever 411 rotates, the support piece 412 accommodated in the frame 421 of the locking pin assembly 420 rotates about the shaft 412-1, thus extending the extensions 414-1 and 414-. The upper pulley 413-1 and the lower pulley 413-2 mounted to the support piece 412 through 2) also rotate in the same direction.

The lower pulley 413-2 located below the support piece 412 rotates and pulls the left side of the cable 800 toward the shaft 412-1, so that the locking pin with the end of the cable 800 fixed thereto. The frame 412 of the assembly 420 moves to the opposite side of the corresponding rail 601. As a result, the locking pin 424 fixed to the end of the frame 412 is disengaged from the opening 601-1 formed in the rail 601 (state of the left part of FIG. 5B).

At this time, the moving length of the locking pin 424 is the linear moving distance (L2 in FIG. 5B) of the lower pulley 413-2.

At the same time, the upper pulley 413-1 mounted to the center portion of the support piece 412 rotates and pulls the right side of the cable 800 toward the shaft 412-1. Thus, the frame of the locking pin assembly of the second locking module 500, to which the end of the cable 800 is fixed, moves to the opposite side of the corresponding rail 602. As a result, the locking pin fixed to the end of the frame is released from the opening 602-1 of the rail 602 (state of the right part of FIG. 5B).

By leaving the openings 601-1 and 602-1 of 601 and 602, the cross bar 700 can move along the rails 601 and 602 by an external force applied thereto.

On the other hand, when the frame 421 of the first locking module 400 moves toward the support member 430, the guide rod 425 fixed to the rear end of the frame 421 is the rear casing 433 of the support member 430 It is fully inserted into the second space portion formed therein, so that the compression spring 427 located on the outer circumferential surface of the guide rod 425 is between the rear end surface of the frame 421 and the inner wall constituting the second space portion in the rear casing 433. Is compressed.

This process is similarly performed in the second locking module 500.

After moving the cross bar 700 to adjust the spacing between the cross bars, if both ends of the cross bar 700 correspond to the new openings of the rails 601 and 602, the first locking module 400 rotated. The external force applied to the lever 411 is removed.

In this state, the restoring force of the compression spring 427 compressed by the guide rod 425 inserted into the second space in the rear casing 433 of the supporting member 430 is the frame 421 of the locking pin assembly 420. ), Thus the frame 421 moves towards the corresponding rail 601. Thus, the locking pin 424 at the tip of the frame 421 is inserted into a new opening of the rail 601.

The movement of the locking pin proceeds in the same manner as in the second locking module 500, so that the cross bar 700 is locked to the rails 601 and 602.

On the other hand, the movement of the frame 421 of the locking pin assembly 420 by the rotation of the lever 411 of the rotating member 410 (that is, the locking pin 424 from the opening 601-1 of the rail 601). At the time of movement of the frame 421 by the restoring force of the compression spring 427 (that is, insertion of the locking pin 424 into the opening 601-1 of the rail 601), the rotation member 410 moves. Maintain the original position.

That is, the guide slot 422 formed horizontally on both sidewalls of the frame 421 of the locking pin assembly 420 extends vertically from both sides of the support piece 414 of the rotating member 410. The rotating member 410 may be maintained even when the frame 421 is moved by the rotation of the lever 411 and the restoring force of the compression spring 427.
