Abstract

PURPOSE: To perform double opening with no trouble also to eliminate unnecessarily moving to a opening/closing position, by connecting each central part of a body and a cover by a toggle mechanism, to equally generate cover opening force by a tension spring in an operating direction of right/left opening. CONSTITUTION: In a condition that a tension spring 10 is provided in an outer side of an L-shaped lever 7 from a position (dead point) of pivotally supporting pin 8, a link 9 is suppressed so as to turn in a direction of opening a cover 2, that is, in the counterclockwise direction till stopping by a stopper 15, to open the cover 2. From this opened condition, when an opening side of the cover 2 is pressed down, the tension spring 10 is overlapped with the position (dead point) of the pivotally supporting pin 8, and force in a direction of opening the cover 2 by the tension spring 10 is decreased to 0, to finally superpose the cover 2 on a body 1. In the case of opening a left side of the cover 2, when lifted the left side of the cover 2 against the tension spring 10 from a closed condition, after the tension spring 10 passes through the dead point, force acts in a direction of opening the cover 2, to open the cover 2 from the left side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-openable roof box, and more particularly to a double-openable roof box mounted on the roof of a vehicle.

[0002]

2. Description of the Related Art As an openable / closable roof box that can be placed on the roof of an automobile, for example, Japanese Unexamined Patent Publication No.
The one shown in Japanese Patent No. 189248 and the one shown in FIG. 8 are known.

In FIG. 8, 1 is a roof box body, 2 is a cover, and 3 is a damper.
A base portion 4 of which is rotatably supported on the left side of the body 1,
The tip of the movable rod 5 is pivotally supported on the right side of the cover 2,
The pressing force of the damper 3 causes the cover 2 to tilt upward with one end of the body 1 as a base point and open.

[0004]

However, in the conventional roof box shown in FIG. 8, for example, the movable rod 5 of the damper 3 is always provided when the cover 2 is closed.
As a result, a force acts on the cover 2 in the direction A, which is a substantially lateral direction, as shown in FIG.
The above-mentioned force is applied to the surroundings, which may cause damage to this part due to fatigue.

Further, when the cover 2 is open, FIG.
As shown in (1), the force is always acting in the B direction, which is the substantially upward direction, and when closing the cover 2, it is necessary to overcome this force and push down the cover 2, which is inconvenient.

Further, in such a conventional roof box, there is only one opening / closing direction (opening / closing portion), and for example, a roof box having an opening / closing portion on the passenger side is restricted by the height of the roof of the parking lot. If you install this on the driver's side,
There is the inconvenience that you cannot open and close from the driver's side.

Therefore, the cover 2 is moved from the closed state of FIG. 9 to that of FIG.
When the cover 2 is opened on the opposite side, that is, on the left side, the fulcrum of rotation of the cover 2 is different from that on the right side.
As indicated by 0, the force exerted by the damper 3 is in the direction indicated by C, which is diagonally upward. Due to the force in the C direction, the cover 2 is displaced to the right when it is raised, and therefore, when the cover 2 is subsequently closed, it does not match the body 1.

The present invention eliminates the above drawbacks.

[0009]

A double-openable roof box according to the present invention comprises a body, a cover, and a toggle mechanism for connecting a central portion of the body and a central portion of the cover.

The toggle mechanism includes a lever having a pivotal support portion at both ends and an intermediate pivotal portion deviated from a line connecting the pivotal end portions, and a link having one end rotatably pivotally supported at the intermediate pivotal support portion of the lever. , A tension spring having one end connected to this link and the other end connected to one of both end pivotal support portions of the lever, and the other end of the lever both end pivotal support portion is provided at a central portion of one of the body and the cover. The link is rotatably supported, and the other end of the link is rotatably supported on the center portion of the other one of the body and the cover.

The lever has a stopper, which prevents the link from rotating in the restraining direction by the tension spring.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, a toggle mechanism 6 is provided between the central upper portion of the body 1 and the central lower portion of the cover.
To connect.

The toggle mechanism 6 includes an L-shaped lever 7
A link 9 extending outward from the L-shaped lever 7, one end of which is rotatably supported by a bent base portion of the L-shaped lever 7 via a pivot pin 8; And a tension spring 10 having one end connected to one end and the other end connected to one end of the L-shaped lever 7, and one end rotatably pivoted to the other end of the L-shaped lever 7 via a pivot pin 11. The lower connecting rod 12 supported, the upper connecting rod 14 whose one end is rotatably supported by the other end of the link 9 via a pivot pin 13, and the link 9 further from the position shown in FIG. It is constituted by a stopper 15 provided on the L-shaped lever 7 in order to prevent the tension spring 10 from rotating in a pulling direction, that is, a counterclockwise direction, and the other end of the lower connecting rod 12 is connected to the body. 1 is fixed to the upper center portion of the cover 1, and the other end of the upper connecting rod 14 is attached to the center of the cover 2. Allowed to secured to the part.

Since the roof box capable of opening according to the present invention has the above-mentioned structure, the tension spring 10 has the L-shaped lever 7 from the position (dead point) of the pivot pin 8 at the bent base of the L-shaped lever 7. When the link 9 is on the outer side of the cover 7, the link 9 is constantly restrained from rotating in the direction of opening the cover 2, that is, counterclockwise until it is stopped by the stopper 15, and the cover 2 opens. However, in the state shown in FIG. 1 in which the right side of the cover 2 is open, the link 9 engages with the stopper 15, so that the link 9 does not rotate counterclockwise any more even if it is pulled by the tension spring 10. .

From this open state, if the opening side of the cover 2 is pushed down against the opening force of the tension spring 10, the L-shaped lever 7 and the link 9 are positioned at the relational position of the tension spring 10 as shown in FIG. It comes to overlap with the position (dead point) of the pivot pin 8, and in this state, the force of the tension spring 10 in the direction to open the cover 2 becomes zero.

When the cover 2 is further pushed down, the tension spring 10 is located inside the L-shaped lever 7 beyond the position (dead point) of the pivot pin 8 as shown in FIG.
In this state, the tension spring 10 applies a downward force to the cover 2 in the direction of closing the cover 2, so that the cover 2 is attached to the body 1
Will be overlaid.

When the left side of the cover 2 is opened, if the left side of the cover 2 is lifted against the tension spring 10 from the closed state shown in FIG. 3, the tension spring 10 will pass the dead point as shown in FIG. After that, the cover 2 acts to open the cover 2 and the cover 2 opens from the left side.

When the cover 2 is closed, the same process as above is performed.

In another embodiment of the present invention, as shown in FIG. 5, upper ends of both ends of the body 1 and lower ends of both ends of the cover 2 are connected by one and the other engaging members 16, respectively.
When one side of the cover 2 is opened, one engaging member 16
The engagement is released, and the cover 2 can be rotated by using the other engagement member 16 as a fulcrum to open and close.

As shown in FIGS. 6 and 7, the engaging member 16 is rotatably supported by one of the body 1 and the cover 2, for example, one end upper portion of the body 1 via a pivot pin 17. A key rod 18 whose upper surface is curved in an arc shape, an operation handle 19 which is connected to the key rod 18 and extends horizontally to the outside of the body 1, and to restrain the key rod 18 in a vertically standing key stop position. Spring 20, a horizontally extending latching rod 21 projecting from the lower end of one end of the cover 2 so as to engage with the upper end key portion of the key rod 18, and this rod 21 serves as the upper end key portion of the key rod 18. And a side wall 22 projecting from the body 1 so as to form a receiver for supporting this from below in an engaged state.

In the above embodiment, for example, when the right side of the cover 2 is opened as shown in FIG. 5, the operating handle 19 of the right engaging member 16 is lifted against the spring 20 as shown in FIG. The rod 18 is rotated counterclockwise in FIG. 7 around the pivot pin 17 to release the engagement with the latch rod 21 and the right end of the cover 2 is lifted, so that the cover 2 is provided at the lower left end thereof. Hook rod 21 of the other engaging member 16
Is supported by the support of the side wall 22, so that it rotates about the latch rod 21.

Similarly, when the left side of the cover 2 is opened, the left side can be opened in the same manner as above by operating the operation handle 19 of the left engaging member 16.

When the open end of the cover 2 is pushed downward to close the cover 2, the latch rod 21 attached to the cover 2 abuts against the upper face of the key rod 18, but the upper face of the key rod 18 is hit. Since the key is curved in an arc, the key rod 18
7 against the spring 20 as the latch rod 21 descends.
As shown in FIG. 5, the key rod 18 is rotated in the counterclockwise direction, and the lock rod 21 is engaged with the key groove 18 ′ of the key rod 18.
By the action of 0, it returns and the latch rod 21 is latched.

Further, in this state, the retaining rod 21 is supported by the side wall 22.

[0026]

As described above, according to the double-openable roof box of the present invention, the opening force actuating direction of the cover by the tension spring 10 is substantially the same in both the right opening and the left opening, and in any case. Also, since the rotation fulcrum of the cover 2 is coincident with the pivot pin 11 at the other end of the L-shaped lever 7, the double opening can be realized without any hindrance, and the cover can be easily closed and opened at its open and closed positions. There are great benefits such as not moving.
