Description

[Detailed description of the invention] The present invention relates to an opening/closing check device for an automobile door.

Automobile doors are attached to the vehicle body so that they can be opened and closed via a hinge body, but the hinge body itself has control means for opening and closing the door. When it is moved, it moves rapidly and is therefore likely to cause contact damage to external objects.

In addition, if it is suddenly exposed to external pressure while it is in the open state or when moving from the open state to the closed state, it will be accelerated without any resistance to the closed state, causing an accident that may cause damage to objects inside and outside. Easy to use.

To this end, automobile doors are equipped with checking devices for controlling the opening and closing speed.

A shown in FIG. 1(a) indicates the positional relationship, and (-) is a partial sectional view thereof.

That is, the car body pillar (8) has a rising part (1)a, which is fixed to the car body pillar (8) by screws or welding, and is in the form of a ``YoC'' font. Il

This resistance force provided the effect of controlling the opening/closing force of the door (9).

However, such a checking device has a large number of parts, which requires time to assemble, and also requires processing steps such as welding and caulking, and the check guide uses rubber as an elastic material. Because of this, phenomena such as aging due to long-term use and aging due to hot and cold temperatures were likely to occur.

In some cases, a metal compression spring may be used as a substitute for the rubber elastic body, but this has the drawback of increasing the size of the device itself.The present invention was created in consideration of these drawbacks. By reducing the number of parts, the number of assembly steps can be reduced, and the rubber body of the check guide can be omitted by providing elastic force to the check arm and check guide. The present invention aims to solve the drawbacks of the prior art.

The present invention will be described below with reference to the illustrated embodiments. FIG. 2 is an assembled front view of the opening/closing check device according to the present invention;
Figure ts3 is an exploded perspective view.

Compared to the conventional example, the present invention is characterized in that the structure of the check guide is simplified and the elastic force of the check arm is used to apply resistance to the check guide.

First, the check guide αQ consists of a check check Ql) made of a flat metal plate and sliders a made of synthetic resin, each of which is installed on one end face of the check check aυ in the vertical direction.

The slider α is a three-dimensional shape, and the inset hole is drilled on one side of the slider α at one end of the check shaft Q0! f
It is equipped with a cylindrical leg part α7Ja that can be inserted with the handles iWt, , and a guide plate α stands up on the opposing surfaces of the leg part aha leaving only the width dimension of the check bale (11) at the left and right ends.
3b, and both sides holding the check 0υ are curved surfaces UC to eliminate resistance.

1. The inset hole was drilled and the opposite of my friend Choesik Keyaki αυ
A connecting hole (141) is drilled through the pair of ends.On the other hand, the check arm is made of spring material and has the same upper and lower central portions bent in a circular shape. Curved surface (2) and 0
The holding plate for holding and fixing the curved surface body (2) (0 U11 face body 611) is equipped with a parallel plate extending in parallel from both sides and another parallel plate @Iwa. The middle part of each of these, which is sandwiched between parallel plates, is provided with a first resistor part 11 which is convexly curved inwardly facing each other from above and below, and a second resistor part 5 (2) (2). There is an intermediate member (2) with a narrow interval held between the resistor parts.

The free end portions of the zero-curved surface body (2) each have a portion extending outward in the right angle direction.

In other words, the extended part becomes the fixed plate @(b), and the fixed plate @(
2) each has one hole @(g).

In addition, a stop hole @b%@b with the same diameter as the hole @- is bored in the retaining plate, and a square slide hole @a through which the check bale αυ can pass with plenty of room is drilled in the center. ing.

First, we will explain the operation when assembled using the opening/closing check device configured as above.
Attach the retaining plate to the specified location on the inner surface of the door (9) with the screws (a) a,
αf9a will be installed, but at this time, work to connect check guide QQ and check arm 4◇, that is, 4th r! A. As shown in Fig. 5, attach the leg a''IJa of the synthetic resin slider a3 to the inset hole drilled in the check bar aυ in the vertical direction with the check bar Oυ as the center. .

The outer diameter of the leg Ha and the inner diameter of the insertion hole 0 are dimensioned with ample margin, so hold it with your fingers to prevent it from falling □5.
The guide plate α3b and the direction of the zero curved surface p are aligned with the axial direction of the guide bale aυ, and the guide plate α3b is sandwiched between the parallel plates @4.

Figure 5 is an enlarged view of its assembly, and shows the inner diameter of the insertion hole opening and the outer diameter of the leg *'am in order to press the slider from the top and bottom by the elastic force of the spring material of υ, which is a curved surface. Even if a gap is created between the diameter and the 9th dimension, it will not dissociate.

After the 0 curved surface body (2) and the check yoke 0υ are connected via the slider, the check yaw force is inserted into the slide hole @a, and then the fixed plate @ (b) comes into contact with the ``holding plate''. When hole @4 and stopper hole @b%@b are aligned, the end face of the fixing plate @@ comes into contact with the side wall part @C provided by the holding plate -, and the fixing plate @@ is completely integrated.

Thus, as described above, the retaining plate is brought into contact with the inner surface of the door (9) at a predetermined location, and the outer surface of the door panel is fixed with the screw @a%Qfla. At this time, the check plate αυ protrudes from the outer surface of the door (9). It will be.

Finally, the rising part lea of the bracket a, which is firmly fixed to a predetermined location of the vehicle body pillar (8) with a screw,
Check the drilling holes (not shown) provided in the ala aD.
Screw the connecting hole.

As a result, the check payload at+ is rotatably attached to the vehicle body pillar (8). The opening/closing check device is fixed to the door and the vehicle body pillar as described above, but as shown in Figure 2, the slider 0 is If the parallel plate is installed in the position of (E) on the check arm, it indicates that the door (9) is fully open, and if external pressure is applied to the door (9), it will slide closer to the closed state. The child α contacts the second resistance portions (E) and (A), and further attempts to suppress and expand the second resistance portions (2) and (E) outward and upward and downward by the force of the slider 03.

As a result, a resistance force against closing is generated in the door (9) and a sudden closing force is prevented.Next, the slider α2 that has crossed the second resistance part (2) (2) is moved to the intermediate part. (
To) Move to position (e).

As a result, the door (9) forms a half-open state. In this case, since the slider α is located between the first resistor part (2) and the second resistor part (e) (2), The door (9) is stable and fixed in the half-open state.0 The same effect occurs when the slider α is moved to the position of the parallel plate in this way.0 That is, the door (9) is in the closed state. 〇Also, the same effect will be given when the door (9) is moved from the closed state to the fully open state.

Figures 6 and 7 are diagrams showing other embodiments, and Figure 96 is a completed diagram with a shank. Figure 1!7 is an exploded perspective view. 01 Like Figure 2, it consists of a check guide ■ and a check arm. In these configurations, the check guide ■ is directly fixed to the door (9), and the check arm ( The difference is that A) is attached to the vehicle body pillar (8) via a bracket ■.

For the check guide (7), a U-shaped metal plate fixing device is fixed with screws to a predetermined location on the inner surface of the door (9), and is attached to the guide plate (to) 03 that stands up in parallel. Two rollers &I01 made of synthetic resin with a small diameter in the center are rotatably mounted.

On the other hand, as shown in figure flIiB, the check arm OI is inserted into the locking hole of the platen (U) by inserting it through the guide hole (to) drilled on the back side of the fixture
Attach Ia@ so that it can rotate freely from the inside to the outside. In this case, the check arm @1 is made of a nine-piece body made of spring material, and the presence of the two resistance parts and parallel parts is explained above. This is similar to the example.

The check arm (4G) is configured to move in contact with the small diameter portion c34 (end) of each of the rollers 0303.

Therefore, the movement relationship between the check guide (7) and the check arm IO when the door (9) is closed, half open, or fully open is also the same as in the above embodiment. In the present invention, a resistance portion is formed on the check arm made of a metal spring material, and a slider made of a synthetic resin material is attached to the check guide so that it can slide with respect to the check arm, so that the check arm follows the movement of the side door. The slider contacts and suppresses the resistive portion, and its resistive force can prevent the sudden -1'j opening/closing state.

As described above, by providing elastic force to the check arm, the rubber-like elastic body can be omitted compared to the conventional example, which prevents the load from decreasing due to temperature differences, and also reduces the number of parts overall. Since it can be completed in less than half the time, it has useful effects such as reducing the assembly man-hours and time required for conventional welding and caulking, and at the same time reducing the manufacturing cost.
