The support frame 8 has a pivot portion 12 which is rotatably engaged with the support groove 7, a pair of side wall portions 13 and 13 which rise from both front and rear ends of the pivot portion 12, and both side wall portions 13 and 13. 1
3 is composed of a top wall portion 14 that connects the upper ends of the three and a central wall portion 15 that is apart from the top wall portion 14 downwardly and that connects the three side walls 13, 13 and the pivot portion 12 together. A clamp member 9 is supported on the upper portions of both side wall portions 13 and 13 via a pivot pin 16 so as to be swingable in the left-right direction of the vehicle. The clamp member 9 is formed in a bell crank shape in which a pair of long and short arms 9 a and 9 b extend in a right angle direction from a base portion supported by the pivot pin 16.
a is opposed to the inner side surface of the central wall 15 of the support frame 8, and the short arm 9
b is arranged so as to face the lower surface of the luggage carrier frame 3 inserted inside the top wall portion 14.

When the long arm 9a is swung in the direction away from the central wall portion 15, the short arm 9b escapes below the luggage carrier frame 3, and the long arm 9a is swung toward the central wall portion 15 side. For example, the short arm 9b pushes up the luggage carrier frame 3 and clamps it against the top wall portion 14.

The cam mechanism 10 includes a lock lever 17 having a pair of front and rear bosses 17a, 17a at its base end, a pair of cams 18, 18 integrally connected to the outer ends of both bosses 17a, 17a, and a boss. Cam shaft 19 rotatably fitted to 17a, 17a, and long arm 9a and both bosses 17 through penetrating holes 20 and 21 of said long arm 9a and central wall portion 15.
and a connecting bolt 22 (see FIG. 5) that adjustably connects the cam shaft 19 between a and 17a. The lock lever 17 has an unlock position A (see FIG. 7A) that tilts outward of the support frame 8 and a lock position B (see FIGS. 3 and 7C) that stands up in the support frame 8. Between the camshaft 19
The lever 17 rotates around, and the protruding portion 17b from the free end of the lever 17 contacts the outer surface of the support frame 8 so that the lever 17 does not rotate beyond the lock position B. There is.

The cam 18 has an unlocking surface 18a and a locking surface 18 which face the outer surface of the central wall portion 15 in correspondence with the unlocking position A and the locking position B of the lock lever 17, respectively.
b. Thus, the unlock surface 18a is attached to the cam shaft 1
The lock surface 18b is formed so that the distance from the center of the cam shaft 9 is relatively short, and the distance from the center of the cam shaft 19 is relatively long.

The central wall portion 15 of the support frame 8 is provided on both cam surfaces 1
The lock lever 17 is provided with a window portion 23 (see FIG. 4) that has a protruding portion 15a that is inserted between 8 and 18, and that avoids interference with the protruding portion 15a. A nut 24 is embedded in the inner surface of the protruding portion 15a, and the support frame 8 is attached by a mounting bolt 25 with a knob 25a that is screwed into the nut 24.
A holding plate 26 for fixing the to the roof R is held.
The holding plate 26 has a long hole 23 through which the mounting bolt 25 penetrates.
An inclined portion 26a which is bent in order to hold the central wall portion 15 of the support frame 8 from its upper outer edge,
It has a hook portion 26b which is engaged with the side edge portion of the roof R in the upper and lower sides.

Next, the operation of this embodiment will be described. When mounting the roof carrier 1 of the present invention, first, as shown in FIG. 7A, with the lock lever 17 tilted to the unlock position A, the left and right support units 2 are set to the fixed positions of the roof R. Install. Since the cam 18 makes the unlock surface 18a face the central wall portion 15, the clamp member 9 swings the short arm 9b downward to support the support frame 8
The distance between the top wall portion 14 and the top wall portion 14 is increased. Therefore, the top wall 1
The carrier frame 3 is inserted between 4 and the short arm 9b.

Next, as shown in FIGS. 7B and 7C, when the lock lever 17 is rotated to the lock position B, the cam 18 integrated with the lock lever 17 is also rotated around the cam shaft 19 to lock the lock. Since the surface 18b is pressed against the central wall portion 15 of the support frame 8, the cam 18 pulls the connecting bolt 22 via the cam shaft 19 by its reaction, so that the long arm 9a of the clamp member 9 causes the central wall portion of the support frame 8 to move. Attracted to the 15 side,
Along with this, the short arm 9b swings upward and presses the platform frame 3 against the top wall portion 14 of the support frame 8. In this way, the luggage carrier frame 3 can be clamped between the top wall portion 14 and the short arm 9b by a one-touch operation of simply rotating the lock lever 17 to the lock position B, and the rotation torque of the lock lever 17 is determined by the cam. Since it is sequentially amplified and transmitted to 18, the long arm 9a, and the short arm 9b, a strong holding force can be exerted on the platform arm 3.
The clamping force can be adjusted in advance by the screwing amount of the connecting bolt 22 into the cam shaft 19.

Next, as shown in FIG. 3, the inclined portion 26a of the holding plate 26 having the hook portion 26b engaged with the side edge portion of the roof R is pressed against the outer edge of the central wall portion 15 of the support frame 8, The support unit 2 can be fixed to the roof R by screwing the mounting bolt 25 inserted through the elongated hole 27 into the nut 24 of the central wall portion 15 and tightening the same. Moreover, the pressing plate 26 can prevent the lock lever 17 from moving to the unlock position A.

In the above embodiment, various design changes can be made without departing from the gist of the present invention. For example, a locking device can be attached to the holding plate 26 or the mounting bolt 25.

[0017]

As described above, according to the present invention, the support frame is provided with the lock lever for rotating between the unlock position and the lock position, and the clamp member is rotated with the rotation of the lock lever to the lock position. Since the cam that operates the lock lever to the clamping position with respect to the carrier frame is connected to the lock lever, the clamp member can be operated by a one-touch operation of simply rotating the lock lever to the lock position. Can be reliably sandwiched by the support frame.
