Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sliding window opening/closing device used in vehicles such as automobiles.

(Prior Art) A plurality of pairs of windows 2 are arranged in the front and back direction on the side part 1b of the vehicle 1 shown in FIG. It can be opened and closed by sliding in the front and rear directions of the vehicle 1 while being guided by. At one corner of the window 2, as shown by a chain line 3, an opening/closing device is provided which is used to open/close the window 2 or to lock the window 2.

FIG. 2 shows a conventional sliding window opening/closing device 4. As shown in FIG. (For example, see Japanese Utility Model Publication No. 48-39771.) When the window 2 is closed, one side of the window 2 comes into contact with the buffer member 6 in the window frame 5 erected on the side 1b of the vehicle 1. ing. A support member 7 is attached to the lower edge of the window 2.
It is fixed by a screw 9 inserted into a bushing 8 fitted in the holder.

On the indoor side (lower side in FIG. 2) of the support member 7, there is a locking member 11 having a locking piece 11a at the free end.
The base of the locking member 11 is pivoted by a shaft 12, and the locking member 11 is moved by the elasticity of a spring (not shown).
The clockwise rotational behavior in FIG. 2 is given.

When the window 2 is closed, the locking member 1
The window 2 is locked in the closed state by fitting the first locking piece 11a into the locking hole 5a provided in the window frame 5. The window 2 is slidably supported by a guide rail (not shown) of a window frame 5 disposed along the lower side of the window 2.

To open the window 2, push the short arm 11b of the locking member 11 into the arm 7a side of the support member 7, rotate the locking member 11 in the direction of arrow 13, and then rotate it in the direction of arrow 14. Just press it.

There is an inconvenience that the window 2 may shift from the open position or move significantly due to the influence of inertia such as acceleration or deceleration while the vehicle is running, or the influence of vibration or impact. In order to prevent this, a member (not shown) is provided between the window 2 and the guide rail to provide appropriate slip resistance.

However, in such a conventional opening/closing device 4, although it is possible to reliably hold the window 2 in the open position, when opening/closing the window 2, the window 2 cannot be opened or closed using the operating force that overcomes the sliding resistance. Since the window 2 must be pressed down, the opening/closing operation of the window 2 is very heavy.

(Purpose of the invention) The purpose of the invention is to securely prevent the window from moving accidentally when the window is closed or stopped at a desired position in a sliding window opening/closing device. It is an object of the present invention to provide an opening/closing device which can be restrained and which can easily and smoothly open and close a window with light weight.

(Structure of the invention) The sliding window opening/closing device of the invention has a case body fixed to a sliding window that is slidably mounted along a guide rail, and a case body that is attached to the sliding window that is slidably mounted along a guide rail. A pair of slides that are provided with a pair of inclined surfaces that are inclined in opposite directions, and that include a wedge insert that can be wedged between each of the inclined surfaces and the guide rail, and an operating shaft that protrudes from the case body. The member is provided so as to be slidable in a direction in which each of the wedge-shaped bodies can be wedged between each inclined surface and the guide rail and separated from each other, and each wedge-shaped body is provided with a sliding member, A locking piece that is constantly biased in a direction to wedge between each inclined surface and the guide rail, and that is removable from a locking hole drilled in a window frame of the vehicle body is provided on the case body. A locking part that includes a protrusion that pushes an operating shaft of one slide member in a direction in which the wedge-shaped body moves away from the inclined surface in conjunction with movement in a direction in which the wedge-shaped body moves away from the locking hole, and an operating part. It is characterized by having the following.

(Example) Hereinafter, the present invention will be explained based on the example shown in each figure after FIG.

In FIG. 3, an opening/closing device 15 is arranged at one corner of the inner surface of the lower end of the window 2. As shown in FIG. In side view, the case body 16 of the opening/closing device 15 has the following features:
It consists of a U-shaped member with an opening facing downward, and a rear plate 16a of the case body 16 is fixed to the window 2 with screws 17. Case body 1
At the left end of the case body 6, the base of the locking member 18, which is approximately L-shaped in plan view, is connected to a horizontal mounting piece 16c (see FIG. (see) with a vertical axis 19.

The locking member 18 is biased in the direction of arrow 21 (FIG. 3) by the elasticity of a compression spring 36, which will be described later. When the window 2 is in the closed state as shown in FIG. The window 2 is locked by engaging with the window 2.

At the left and right ends of the opening of the case body 16, there are sloped surfaces whose pointed portions face inward toward each other, guide surfaces 22a and 23a whose upper surfaces are substantially horizontal, and whose lower surfaces are inclined upwardly toward each other. 22
A pair of wedges 22, 23 forming b, 23b are horizontally installed in the front-rear direction.

Slide members 24 and 25 are fitted into the left and right parts of the opening of the case body 16, and the outward wedge-shaped recesses 24a and 25a provided in these slide members 24 and 25, respectively, are connected to the wedges 22 and 23.
It fits into the wedges 22 and 23 in a substantially complementary shape.

By providing wedges 22 and 23 at the opening of the case body 16, square guide holes 26 and 27 are formed at the left and right ends of the opening. Further, by providing the wedge-shaped recesses 24a, 25a in the slide members 24, 25, horizontal operating shafts 28, 29 are formed at the upper portions of the slide members 24, 25, and horizontal slide surfaces 31a, 32a are formed at the lower portions of the slide members 24, 25. and inclined surfaces 31b and 32b that slope upward inward.
Wedge-shaped bodies 31 and 32 having wedge-shaped points facing outward are formed.

Operating shafts 28, 29 of slide members 24, 25
are loosely fitted into the guide holes 26, 27 of the case body 16, and the slide members 24, 2
The wedge bodies 31 and 32 of No. 5 are slidably in contact with a guide rail 33 disposed along the lower part of the window 2.

Each end of a compression spring 36 is in pressure contact with the recesses 34 and 35 provided at the inner ends of the slide members 24 and 25, and the elasticity of the compression spring 36 causes both the slide members 24 and 25 to move in the left-right direction. Their respective wedge bodies 31, 32 are biased outwardly toward each other.
is designed to fit between the inclined surfaces 22b, 23b of the wedges 22, 23 and the guide rail 33.

As shown in FIG. 5, the locking piece 18a of the locking member 18 is located at the base of the locking member 18 at a position substantially opposite to the locking piece 18a.
The end surface 28a of the actuating shaft 28 is pushed inward of the case body 16 by rotating counterclockwise in the figure about the shaft 19 from the state in which it is engaged with the locking hole 5a. A protrusion 18b is formed as a movable cam surface.

Furthermore, an operating portion 18c extending in a plate shape toward the indoor side is connected to the base of the locking member 18.

Next, the function of this embodiment will be explained along with its operating procedure.

As shown in FIG. 3, in order to open the window 2 in the closed state, the operating portion 18 of the locking member 18 in FIG.
c in the direction of arrow 37 to release the locking piece 18a.
Remove it from the locking hole 5a as shown in Figure 7a.

Then, due to the above rotation of the locking member 18, the protrusion 18b is displaced from the diagonally downward position in FIG. 5 to the right position of the shaft 19 as shown in FIG. 7a.
The actuating shaft 28 is pushed into the case body 16 by a small amount to displace the slide member 24 to the inside of the case body side 16, as shown in FIG. 6a.

As a result, the wedge-shaped body 31 of the slide member 24
is separated from the inclined surface 22b of the wedge 22.

If the wedge body 31 of the slide member 24 is wedged between the wedge 22 and the guide rail 33 as shown in FIG. When attempting to do so, the wedge body 31 bites deeper and prevents the movement of the window 2, but as described above, the wedge body 31 is separated from the wedge 22 as shown in FIG. 6a. When the wedge member 31 is moved, the wedge action by the wedge member 31 is released, and the action to prevent the movement of the window 2 is eliminated.

The wedge-shaped body 32 of the other slide member 25 is inserted into the wedge 23 when the opening/closing device 15 moves in the direction of the arrow 38.
Since it is in the direction away from the guide rail 33, it does not come into strong pressure contact with the upper surface 33a of the guide rail 33.

Therefore, the locking member 18 is rotated to the position shown in FIG. 7a, and while the slide member 24 is kept pushed inward of the case body 16, the operation portion 18c of the locking member 18 is rotated. By further pushing to the right in FIG. 7a, the window 2 can be moved lightly and smoothly in the direction of arrow 38.

With window 2 released to the appropriate position,
Release the pressure on the operating part 18c of the locking member 18,
When the locking member 18 is returned to the original position shown in FIG. 5, the operating shaft 28 moves outward following the protrusion 18b of the locking member 18 due to the biasing force of the compression spring 36, and the slide member The wedge inserting body 31 of No. 24 returns to the state of being wedged between the wedge 22 and the guide rail 33 as shown in FIG.

In this way, when the wedge bodies 31 and 32 of both slide members 24 and 25 are wedged between the wedges 22 and 23 and the guide rail 33, the window 2 cannot be moved to the left or right. Even if you try to move to the right, the left wedge body 31
However, when the window 2 moves to the left, the right wedge bodies 32 bite further and prevent the window 2 from moving in that direction.
It will not move unexpectedly due to vibrations of the vehicle or inertia when starting or stopping suddenly.

In order to move the window 2 and the opening/closing device 15, which have been opened to an appropriate position, in the closing direction indicated by the arrow 39, as shown in FIG. Just push it to the left against the

Then, the wedge-shaped body 32 of the slide member 25 is inserted into the wedge 2.
3, the above-mentioned leftward restraint of the window 2 due to the wedge action of the wedging body 32 is released, and the window 2 is smoothly moved leftward with light force.

At this time, the wedge-shaped body 3 of the other slide member 24
1, due to the frictional resistance of the guide rail 33, the wedge 2
Since it acts in the direction away from window 2,
movement in the direction of arrow 39 is not prevented.

Immediately before the window 2 contacts the window frame 5, the locking piece 18a of the locking member 18 climbs over the window frame 5, and when the window 2 contacts the window frame 5 and closes completely, the locking piece 18a crosses the window frame 5. 5 engages with the locking hole 5a, and the window 2 is locked in the closed state.

When adjusting the opening amount by moving the window 2 left and right at an appropriate position, rotate the locking member 18 shown in FIG. At the same time, as shown in FIG. 6c, the actuating shaft 29 is pushed to the left and the slide member 25 is pushed inward, so that the wedge bodies 31, 3 of both slide members 24, 25
2 may be separated from the wedges 22 and 23.

In this state, the opening/closing device 15 should be
8, 39, the wedge inserts 31, 32 of the slide members 24, 25 will slide into the wedges 22, 2.
3 and the guide rail 33, the opening/closing device 15 and the window 2 can be moved lightly on the guide rail 33 in any direction.
And it can slide smoothly.

After sliding the window 2 to the desired position, when the pressure on each slide member 24, 25 is released, both slide members 24, 25 are moved by the compression spring 36.
Due to the elasticity of the wedges 22, 2, as shown in FIG.
3, the opening/closing device 15 and the window 2 are prevented from sliding in either the left or right direction.

Furthermore, the wedge bodies 31 and 32 are connected to the slide member 2.
4 and 25, it may be a roller-shaped member pivotally connected with an axis in the front-rear direction.

(Effects of the invention) As described above, according to the invention, when opening and closing a sliding window, when the window is closed or stopped at a desired opening degree, the window moves randomly. It is possible to securely restrain the window so that it does not occur, and the window can be opened and closed easily and smoothly.

Furthermore, when the locking piece of the locking member is removed from the locking hole drilled in the window frame of the vehicle body, at the same time, the operating shaft of one of the slide members is pushed by the protrusion of the locking member, Since the restraint in the direction in which you try to open the window is automatically released, you can open the window with a single touch, and all you have to do is release the locking piece of the locking member from the locking hole and push one operating shaft. There is no need to perform the loading operation twice, and the operation is simple.
