【Example】

 FIG. 1 shows a partial front view of the positioning mechanism provided in the partition wall, and FIG. 2 shows a side view of that portion. A horizontally long bracket plate 7 is arranged in the partition wall W, and a support shaft 3 of the handle 1 is rotatably fitted to a boss metal fitting 71 provided at the center thereof. The handle 1 has a long plate shape, the center of which is fixed to the support shaft 3, and is tilted in the left-right direction (FIG. 1) in the locked state shown in the drawing. The handle 1 is entirely inclined in the front-rear direction (left and right in FIG. 2), and the upper and lower ends of the handle parts 13 and 14 are exposed in the openings W1 and W2 provided above and below the partition wall W. There is.

At the middle position between the upper and lower halves of the handle 1, one end of each lock bar 2A, 2B comes from a later-described lock member provided at the left and right ends of the partition wall W, and the handle bar surface is bent and bent. Is rotatably locked in the through hole (Fig. 3).

FIG. 4 shows details of one of the lock members, and the other lock members have the same structure. The lock member 8 is a rod body which is supported by a bracket W3 so as to be horizontally movable. The lock member 8 is made to project to the side of the partition wall W by a compression vane 85 provided between the locking piece 81 on the outer periphery of the bracket W3 and the wall of the bracket W3. As a result, it is in a locked state by penetratingly engaging with the locking hole of the mountain bracket R1 provided on the luggage compartment wall R.

A substantially V-shaped operation lever 82 is provided by abutting one end behind the locking piece 81. The operation lever 82 is pivotally supported at the center, and the other end is connected by a connecting fitting 83. The lock bar 84 is connected. Then, as shown by the arrows in FIG. 4, when the compression spring 85 biases the lock member 8 to project, the operation lever 82 is biased in the clockwise direction and the lock bar 84 is biased upward. To be done.

The lock bar 84 is connected to the lock bar 2A extending in the horizontal direction via an intermediate link (not shown), and the lock bar 2A is biased in the direction shown by the arrow in FIG. Similarly, since the lock bar 2B is also urged in the direction of the arrow in the figure by the compression spring provided in the other lock member, a clockwise rotational force acts on the handle 1 and the stopper provided on the bracket plate 7 One side of the handle 1 contacts the pin 72 and is held in the posture shown in the figure.

The center portion of the other side surface of the handle 1 is a convex portion 11 protruding in a mountain shape having a gentle hem, and the upper half of the protruding end of the convex portion 11 is a rectangular concave portion 12. A cam member 4 is provided with the tip close to the convex portion 11 described above, and the cam member 4 has a substantially elliptical shape with the pointed tip, and its center is rotated around a spindle 5 provided on the bracket plate 7. It is rotatably supported.

A coil spring 6, one end of which is fixed to a locking pin 74 of the bracket plate 7, is connected to the base end of the cam member 4, and the cam member 4 is maintained in a horizontal posture by its urging force. The tip end of the cam member 4 is located within the locus through which the convex portion 11 passes when the handle 1 is rotated in the unlock direction (arrow in FIG. 1). The handle 1 can be rotated until one side thereof comes into contact with another stopper pin 73 provided on the bracket plate 7 (a chain line in FIG. 1).

In the positioning mechanism having the above structure, when the locked state shown in FIG. 5A is changed to the unlocked state, the urging force received from the lock bars 2A and 2B by the handle 1 as shown in FIG. 5B. Rotate counterclockwise against. When the convex portion 11 of the handle 1 comes into contact with the tip of the cam member 4 during the rotation operation, the cam member 4 rotates clockwise against the urging force of the coil spring 6 and tilts the tip downward. When the handle 1 is further rotated, the sharp tip of the cam member 4 rides over the convex portion 11 and engages with the concave portion 12 formed in the upper half of the projecting end (FIG. 5 (c)). As a result, the return rotation of the handle 1 is blocked, and in this state, the operating lever 82 is rotated counterclockwise via the lock bars 2A and 84 (Fig. 4), and the lock member 8 is retracted (Fig. 4). Chain line), unlocked.

In order to cancel the unlocked state, when the handle is further rotated until it comes into contact with the stopper pin 73, the tip of the cam member 4 is disengaged from the recessed portion 12 of the handle 1 and the coil spring 6 urges it to level again. Return to the posture (FIGS. 6A and 6B). After that, when the handle 1 is released, it rotates back by the urging force of the compression spring in the clockwise direction, and the cam member 4 whose tip abuts the moving convex portion 11 rotates counterclockwise and the tip moves upward. It tilts toward (FIG.6 (c)). In this posture, the tip of the cam member 4 does not engage with the concave portion 12, and the handle 1 rotates back until it comes into contact with the stopper pin 72 (FIG. 5 (a)) to be in the initial locked state.

Thus, since the locking state and the unlocking state of the positioning mechanism can be switched only by rotating the handle 1 with one hand, the operability is excellent. Further, since a complicated link mechanism or the like is not used, it is compactly stored in the partition wall W.

In this embodiment, openings W1 and W2 are provided on the front and back sides of the partition wall W, and the entire handle 1 is inclined in the front-rear direction so that the handle 1 is vertically moved to the front side in each of the openings W1 and W2. Since the grip portions 13 and 14 at the ends are positioned, the positioning mechanism can be operated from either side of the partition wall W, and the operability is further excellent.
