[0003] As a conventional positioning mechanism of this kind, there are many mechanisms in which a lock member is protruded from the outer periphery of a partition wall by a compression spring and is engaged with a bracket of a luggage compartment wall so that the partition wall is always fixed. When the partition wall is moved, the lock member is retracted by operating a handle provided on the partition wall to be in an unlocked state, but a mechanism for holding the handle in this state and preventing return is required. .

[0004] Therefore, a handle that prevents return of the handle with a latch or a stopper pin, or that has a turnover structure is used.

[0005]

[Problems to be Solved by the Invention] However, in the case of using the conventional latch, it is difficult to operate the device because both hands need to be used. It is necessary to provide a complicated link mechanism and the like, the structure becomes complicated and large, and it is difficult to compactly store it in the partition wall.

An object of the present invention is to solve such a problem and to provide a compact positioning mechanism for a movable partition wall which is excellent in operability.

[0007]

To explain the structure of the present invention, a positioning mechanism for a movable partition wall W which partitions a luggage compartment of a luggage car and is movable to change the luggage compartment volume. A movable partition wall W provided with a handle 1 provided on the partition wall W and a lock member 8 provided at a predetermined location on the outer periphery of the movable partition wall W and engaged with or disengaged from the cargo room wall R by operating the handle 1 In the positioning mechanism described above, the handle 1 is rotatably provided on the support shaft 3, and the urging means 85 for urging the handle 1 in the direction in which the lock member 8 is engaged is provided. A cam member (4) is formed, which is formed rotatably by the support shaft (5), is urged to a fixed posture by the urging means (6), and has a tip projecting into the movement locus of the handle protrusion (11). And the above Han When rotational operation against the biasing force of Le 1, the cam member 4 is pushed by the convex portion 11 of the way of movement
When the handle 1 is tilted at a predetermined angle, the tip of the handle 1 is engaged to prevent the return rotation of the handle 1.
It is formed in.

[0008]

In the above configuration, in order to unlock the steering wheel, the handle 1 is rotated against the urging force. At this time, the cam member 4 is tilted by being pushed by the moving convex portion 11, and its tip engages with the concave portion 12 of the handle 1 at a predetermined angular position where the engagement between the lock member 8 and the cargo room wall R is released. .
As a result, the return rotation of the handle 1 is prevented, and the unlocked state is maintained.

When the handle 1 is further rotated against the urging force, the engagement between the cam member 4 and the concave portion 12 is released, and when the handle 1 is released at this point, the handle 1 is rotated back, and the lock member 8 is brought into contact with the cargo room wall R. Engage. When the handle 1 is rotated back, the moving convex portion 11 again pushes the tip of the cam member 4 to tilt it, but the tilting direction is reversed, so the concave portion 1
2 does not engage.

Thus, the lock and the unlock can be switched only by rotating the handle 1, and one-hand operation is possible, so that the operability is excellent. Further, since a complicated link mechanism or the like is not required, it is compactly stored in the partition wall W.

[0011]

FIG. 1 is a partial front view of a positioning mechanism provided in a partition wall, and FIG. 2 is a partial side view thereof. A long bracket plate 7 is disposed in the partition wall W in the horizontal direction, and the support shaft 3 of the handle 1 is rotatably fitted to a boss 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 inclined in the left and right (FIG. 1) directions in the locked state shown in the figure. The handle 1 as a whole is also inclined in the front-back (left-right in FIG. 2) direction,
The upper and lower ends of the partition wall 14 are exposed in openings W1 and W2 provided on the front and back of the partition W.

At an intermediate position between the upper and lower halves of the handle 1,
One ends of the lock bars 2A and 2B extend from lock members (described later) provided at left and right ends of the partition wall W, and are bent and rotatably locked in through holes in the handle plate surface (FIG. 3).

FIG. 4 shows the details of one of the lock members, and the other lock members have the same structure. The lock member 8 is a rod supported by the bracket W3 so as to be horizontally movable, and is protruded to the side of the partition wall W by a compression spring 85 provided between the locking piece 81 on the outer periphery thereof 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-shaped bracket R1 provided on the luggage compartment wall R.

A substantially V-shaped operating lever 82 is provided by abutting one end behind the locking piece 81. The operating lever 82 is pivotally supported at the center and has a connecting bracket 8 at the other end.
The lock bar 84 is connected by 3. Then
As shown by arrows in FIG. 4, when the lock member 8 is protruded and urged by the compression spring 85, the operation lever 82 is pressed.
Is urged to rotate clockwise, and the lock bar 84 is urged upward.

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 urged in the direction shown by the arrow in FIG. Similarly, since the lock bar 2B is also urged in the direction of the arrow by a compression spring provided on another lock member, a clockwise rotational force acts on the handle 1 and the stopper pin 72 provided on the bracket plate 7 And one side surface of the handle 1 is in contact with the handle 1 so as to be held in the illustrated position.

The central portion of the other side surface of the handle 1 protrudes in a mountain shape having a gentle hem to form a convex portion 11,
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 its tip close to the protruding portion 11. The cam member 4 has a substantially elliptical shape with a sharp tip, and the center of the cam member 4 is rotatable about a support shaft 5 provided on a bracket plate 7. It has been supported.

A coil spring 6 having one end 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 the urging force. The tip of the cam member 4 is located within a locus through which the protrusion 11 passes when the handle 1 is rotated in the unlocking direction (arrow in FIG. 1). The rotation of the handle 1 is possible until one side thereof abuts on another stopper pin 73 provided on the bracket plate 7 (a chain line in FIG. 1).

In the positioning mechanism having the above structure, FIG.
To change from the locked state shown in FIG. 5A to the unlocked state, as shown in FIG. 5B, the handle 1 is rotated counterclockwise against the urging force received from the lock bars 2A and 2B. When the projection 11 of the handle 1 abuts on 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 protruding end (FIG. 5C).
Thereby, the return rotation of the handle 1 is prevented, and in this state, the operation lever 82 is rotated counterclockwise through the lock bars 2A, 84 (FIG. 4), and the lock member 8 is retracted (FIG. 4). (Chain line) and unlock.

In order to cancel the unlocked state, when the handle is further rotated until the handle comes into contact with the stopper pin 73, the tip of the cam member 4 is disengaged from the concave portion 12 of the handle 1 and is again leveled by the urging force of the coil spring 6. Return to the posture (FIGS. 6A and 6B). Thereafter, when the handle 1 is released, the handle 1 is rotated clockwise by the urging force of the compression spring, and the cam member 4 whose tip abuts the moving convex portion 11 rotates counterclockwise, and the tip is moved upward. It tilts toward (FIG. 6 (c)). In this position, the tip of the cam member 4 does not engage with the concave portion 12, and the handle 1 returns and rotates until it comes into contact with the stopper pin 72 (FIG. 5).
(A)) The initial lock state is set.

Thus, the operability is excellent because the locked state and the unlocked state of the positioning mechanism can be switched by only rotating the handle 1 with one hand. 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 of the partition wall W, and the entire handle 1 is tilted in the front-rear direction. Since the grip portions 13 and 14 are located, the positioning mechanism can be operated from either side of the partition wall W, and the operability is more excellent.
