DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window opening / closing mechanism, which is small in size, has good workability, and can withstand a strong impact.

[0002]

2. Description of the Related Art Some vehicles used in a special environment are provided with a vehicle outer panel capable of withstanding an extremely strong external impact, and are required to have an extremely high level of weather resistance and confidentiality. There are different types of vehicles. As the above-mentioned strong impact, there is an impact or the like that occurs when a small object flying from the outside collides with a vehicle, and the vehicle outer panel has an extremely strong strength enough to bounce off the flying small object. Need to be.

[0003] In such a special type of vehicle, a launching device for launching a small object sometimes launches a small object from the inside of the vehicle to the outside. For this reason, a window is formed in the vehicle outer panel, and a small object is emitted to the outside through the window. When the small object is not to be emitted to the outside, the window is covered and covered with a closing member (such as a closing plate). This closing member (such as a closing plate) is also required to have strength enough to withstand the strong impact described above. Moreover, since extremely high levels of weather resistance and confidentiality are required, a mechanism for opening and closing the window for opening and closing the opening and closing member (such as a closing plate) has been devised (details will be described later).

Here, a conventional example of a window opening / closing mechanism provided in the above-mentioned special type of vehicle will be described with reference to FIGS.

FIGS. 4A and 4B show a vehicle window opening / closing mechanism according to a first conventional example. In this conventional example, a window 2 is formed in a vehicle outer panel 1, and a guide fixing portion 3 is formed on a periphery of the window 2 on a surface of the vehicle outer panel 1 on the vehicle inner side. The guide fixing part 3 has a boss shape,
A female screw is formed on the inner peripheral surface, and the guide portion 4
Fixed. The guide portion 4 holds a spherical closing member 5 rotatably and rollably. The closing member 5 is a hollow sphere, a part of which is formed with an opening 5a which is a through hole, and a handle 6 is fixed.

For this reason, the operator inside the vehicle grasps the handle 6 and moves it up and down (moves in the direction of arrow A in FIG. 4B), whereby the closing member 5 rotates (rolls). 4 (a), the opening 5a is opened to face the outside of the vehicle, or as shown in FIG. 4 (b), the window 2 is covered and closed by the closing member 5 as shown in FIG. 4 (b). Or you can. The opening 5a may be oriented in each direction of the window 2 by gripping the handle 6 and moving the handle in the vertical and horizontal directions.

In the window opening / closing mechanism shown in FIGS.
Since the opening area of the opening 5a is small, the open state (FIG. 4)
Even in the case of (a), the probability that a small object flying from the outside enters the inside of the vehicle through the opening 5a is small, and the small object flying from the outside is highly shielded. There is an advantage. Further, since the closing member 5 is spherical, the opening 5a can be directed in each direction in the window 2, and there is an advantage that the launching device 10 can launch a small object in each direction.

FIGS. 5A and 5B show a vehicle window opening / closing mechanism according to a second conventional example. In this conventional example, a window 22 is formed in a vehicle outer plate 21, and a female screw is formed on an inner peripheral surface of the window 22. Disc-shaped closing plate 2
3, a male screw is formed on the outer peripheral surface, and a handle 24 is fixed.

[0010] For this reason, the operator inside the vehicle grasps the handle 24, applies the closing plate 23 to the window 21, and rotates (rotates in the direction of arrow B in FIG. 5B). 5A, the closing plate 23 is removed from the window 22 to be in an open state, or as shown in FIG. 5B, the closing plate 23 is screwed to the window 22 to cover and close the window 22. It can be closed.

[0011] From the inside of the vehicle to the outside, the launching device 1
When a small object is fired at 0, the shooting operation is performed with the distal end of the firing device 10 inserted into the window 22 in an open state as shown in FIG.

In the window opening / closing mechanism shown in FIGS.
The structure is simple, and in the closed state, the closing plate 23 is screwed firmly to the vehicle outer plate 21. Therefore, even if the impact force of a small object flying from the outside is considerably strong. Thus, a small object that has collided with the closing plate 23 can be reliably rebounded.

FIGS. 6A and 6B show a vehicle window opening / closing mechanism according to a third conventional example. In this conventional example, a window 32 is formed in a vehicle outer panel 31. The closing plate 33 is
At the position on the inner side of the vehicle below the window 32, it is attached to the vehicle outer panel 31 by a hinge 34 so as to be openable and closable. In addition, among the surfaces of the closing plate 33 on the vehicle interior side, the windows 32

[0015] From the inside of the vehicle to the outside, the launching device 1
When a small object is fired at 0, a firing operation is performed with the distal end of the firing device 10 inserted into the window 32 in an open state as shown in FIG.

The window opening / closing mechanism shown in FIGS. 6A and 6B has the advantages that the structure is simple and inexpensive, and that the opening / closing operation is excellent (the closing plate 33 can be opened / closed easily and in a short time). is there.

It is also conceivable that the closing plate 33 is installed on the surface of the vehicle outer plate 31 on the vehicle exterior side by a hinge structure (a structure similar to that shown in FIG. 6) so as to be openable and closable. Then, the opening / closing mechanism becomes complicated, so that it is not employed in the special vehicle as described above.

[0018]

By the way, FIG. 4 (a)
The conventional window opening / closing mechanism shown in (b) has a drawback that the structure is complicated and expensive.

In the conventional window opening / closing mechanism shown in FIGS. 5A and 5B, the closing plate 23 is rotated and screwed into
There is a drawback that the window 22 cannot be opened and closed quickly because of the opening and closing operation, and there is a problem in operability.

In the conventional window opening / closing mechanism shown in FIGS. 6 (a) and 6 (b), the impact force applied to the closing plate 33 is supported by the hinge 34 and the locking handle 35. However, there is a disadvantage that the hinge 34 and the lock handle 35 obstruct the operation when the firing device 10 is operated. Further, it is difficult to seal rain and the like, and there is a problem in terms of weather resistance and confidentiality.

In the end, conventional window opening and closing mechanisms used for special vehicles that require a very high level of weather resistance and confidentiality while shielding small objects flying from the outside have advantages and disadvantages. At present, there is no ideal window opening / closing mechanism.

In view of the above prior art, the present invention has a simple and inexpensive structure, yet has a high shielding property against small objects,
It is an object of the present invention to provide a vehicle window opening / closing mechanism having weather resistance and confidentiality, capable of performing a quick opening / closing operation, and easily performing a firing operation.

FIG. 1 is a sectional view showing a vehicle window opening / closing mechanism according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is an explanatory view showing an operation state.

As shown in FIG. 1 and FIG.
1 has a window 102 formed therein. The vehicle outer panel 101
It is made of a member having extremely high strength enough to bounce a small object flying from the outside. A boss 103 is attached to the vehicle outer panel 101 at a position below the window 102 in a penetrating state.

The handle 104 includes a shaft portion 104a and a grip portion 104b integrally formed at an inner end of the shaft portion 104a. This handle 104
The shaft portion 104a is fitted and installed coaxially with the boss 103. Therefore, the shaft 104 of the handle 104
a is disposed so as to penetrate the vehicle outer plate 101 from the vehicle interior side to the vehicle exterior side via the boss 103,
Further, the grip portion 104b is arranged so as to be located on the vehicle inner side. Moreover, the shaft portion 104a of the handle 104
Can slide along the axial direction of the shaft portion 104a, and
The shaft 104a can be rotated along the circumferential direction.

The closing plate 105 is connected to the shaft 1 of the handle 104.
04a is fixedly installed at the tip (the end on the vehicle exterior side). Therefore, in the present embodiment, the closing plate 105 is arranged outside the vehicle. The closing plate 105 is formed of a member having extremely high strength enough to bounce a small object flying from the outside.
Is covered from the outside of the vehicle so that the window 102 can be closed.

The spring (compression coil spring) 106
It is mounted between the boss 103 and the shaft 104a of the handle 104. This spring 106 is attached to the handle 1
A spring force is generated to urge the vehicle 04 toward the inside of the vehicle (toward the passenger compartment). Therefore, the spring force of the spring 106 is transmitted to the closing plate 105 via the handle 104, and the closing plate 105 has a force for pressing the closing plate 105 against the vehicle outer plate 101 from the outside of the vehicle toward the inside of the vehicle. Works.

Of the surface of the vehicle outer panel 101 on the vehicle exterior side,
An annular seal 107 is fixed and arranged on the periphery of the window 102 so as to surround the periphery of the window 102. On the other hand, an annular projection 105 a is formed on the outer peripheral edge of the closing plate 105 and at a portion facing the vehicle outer plate 101.
The projection 105a is located on the outer peripheral side of the seal 107, and the projection height of the projection 105a is

The shielding property against a small object flying from the outside is extremely high.

Further, since the impact force caused by the small object flying from the outside is received by the vehicle outer plate 101, members inside the vehicle such as the steering wheel 104 and the boss 103 have large strength. Is not required, and members inside the vehicle such as the handle 104 can be reduced in size. Therefore, at the time of a firing operation (to be described later) performed in the open state, members inside the vehicle such as the handle 104 do not hinder the firing operation, and operability is improved.

Further, in the closed state shown in FIG.
Since the seal 107 is located on the inner peripheral side of the outer plate 05a and the protrusion 105a is pressed against the vehicle outer plate 105 by a spring force, even if a rotational force acts on the closing plate 105, the protrusion 105a When the sealing plate 105 hits the seal 107 fixed to the vehicle outer plate 101, the closing plate 105 rotates (the shaft portion 10).
4a).
That is, the protrusion 105a, the seal 107, and the spring 1
06 prevents the closing plate 105 from rotating around the shaft 104a in the closed state (restriction).
That is, a locking mechanism is configured.

Next, with reference to FIGS. 3A to 3C, an operation for opening the window 102 will be described. In order to open the handle, first, an operator inside the vehicle grips the grip portion 104b of the handle 104 and, as shown in FIG. From the inside of the vehicle toward the outside of the vehicle (along the direction of arrow C). In this case, the shaft portion 104a slides from the inside of the vehicle to the outside of the vehicle, and the closing plate 105 floats from the vehicle outer plate 101,
The rotation lock by the lock mechanism described above is released.

Next, as shown in FIG. 3 (b), the handle 104 is rotated by 180 ° while the handle 104 is pushed out of the vehicle. By doing so, the shaft 104a rotates, and the closing plate 105 rotates 180 ° about the shaft 104a as a center of rotation, and is located at a lower position.

Next, as shown in FIG. 3C, when the operator releases the handle 104, the closing plate 105 is moved toward the vehicle outer plate 101 by the spring force of the spring 106, and the protrusion 105a is moved. Abuts / contacts vehicle outer plate 101. The state shown in FIG. 3C is the open state.

3 (c), the operator inserts the tip of the launching device 10 into the window 102 and performs a launching operation to launch a small object from inside the vehicle to the outside.
