[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automobile door checker.

[0002]

2. Description of the Related Art Generally, as shown in FIGS. 6 and 7, one end of a check plate 1 is pivotally connected to a bracket 4 of a vehicle body 3 by pins 2 and the other end of the check plate 1 is screwed into a door 5 as shown in FIGS. 6, penetrates a through hole 7 a of the case 7 attached thereto, and is elastically supported vertically by a pair of guides 8, 8 housed in the case 7. Each of the above guides 8, 8
The elastic members 9, 9 urge the check plate 1.

On both sides of the check plate 1 in the width direction, there are formed ridges 1a, 1a extending longitudinally over the front and rear positions of the half-open position F of the door 5, respectively, and each of the ridges 1a, 1a is formed. At the half-open position F, there is formed a moderation recess 1b into which the guides 8, 8 are fitted to hold the door 5 at the half-open position F. The other end of the check plate 1 is in contact with the case 7 and
Is held at a fully open position G.

[0004] The check plate 1 includes guides 8,
8 restricts the movement in the up and down direction, while the upright portions (see reference numeral 18a in FIG. 1) formed on both sides in the width direction of the guides 8 and 8 restrict the movement in the width direction.
At the time of opening / closing of the check plate 1, the other end side of the check plate 1 is prevented from swinging in the width direction, and interference with the peripheral edge of the through hole 7a of the case 7 is prevented so that interference sound (swinging sound) is not generated.

[0005]

However, the gap between the check plate 1 and the rising portions of the guides 8, 8 may vary due to the accuracy of the parts. If the gap is large, the check plate 1 moves in the width direction. Therefore, the check plate 1 rattles and the above-mentioned interference sound is generated. Conversely, if the gap is small, the movement of the check plate 1 in the width direction is tightly regulated, so that the load due to the contact increases, and the opening / closing operation feeling of the door 5 deteriorates. Moreover, if used for a long period of time, the rising portions of the guides 8, 8 will be worn and the gaps will widen.
There is a problem that the check plate 1 rattles or the above-mentioned interference sound is generated.

Accordingly, an object of the present invention is to provide an automobile door checker which can prevent generation of abnormal noise due to deflection of a check plate for a long period of time.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, one end of a check plate is pivotally connected to a vehicle body, and the other end of the check plate passes through a case mounted in a door and is housed in the case. In the automotive door checker, which is elastically supported in the vertical direction by a pair of guides, rising portions for guiding both side portions of the check plate are formed on both sides in the width direction of each of the guides. An elastic portion that has a cavity that is a vertical hole and that can be elastically deformed in the width direction is formed at one of the protrusions at the half-open position and the fully-open position on both sides of the check plate. It is characterized by.

[0008]

According to the present invention, either one of the upright portions of the pair of guides housed in the door case or the projecting portions at the half-open position and the fully-open position on both sides of the check plate is a cavity which is a vertical hole. To form a resilient portion capable of being elastically deformed in the width direction to reduce the gap between the check plate and the rising portion of the guide. As a result, the check plate does not rattle and does not interfere with the periphery of the through hole of the case, so that the conventional interference noise does not occur.

[0009] In addition, due to the bending of the elastic portion having a cavity which is a vertical hole formed at one of the protruding portions at the half-open position and the full-open position of the rising portion of the guide or both sides of the check plate, the accuracy of the parts is reduced. Irrespective of the variation in the load, the load due to contact is unlikely to increase, so that the opening / closing operation feeling of the door is improved, and the abrasion of the rising portion of the guide can be prevented, and the durability is improved.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. The parts having the same configuration and operation as those of the prior art shown in FIG. 6 and subsequent figures are given the same reference numerals, and detailed description is omitted.

As shown in FIG. 1 and FIG.
Reference numeral 18 basically has the same shape as that of the related art, has a substantially trapezoidal cross section, and has rising portions 18a on both sides in the width direction.

Each of the rising portions 18a, 18a is formed in a triangular shape when viewed in a plane, and the inner width P between the tops 18b, 18b is larger than the outer width Q of both sides 1d, 1d of the check plate 1. There is no gap, in other words, it is set to such an extent that both sides 1d, 1d of the check plate 1 slidably contact the tops 18b, 18b of the rising portions 18a, 18a.

Each of the rising portions 18a has a vertical cavity (hole) 18 near the top 18b.
c, 18c are respectively formed and the cavities 18c, 18c
Thereby, the tops 18b, 18b become elastic portions capable of elastically deforming (deflecting) in the width direction.

With the above construction, the case 7 attached to the door 5 restricts the movement of the guides 18, 18 in the width direction.
At the tops 18b, 18b of the rising portions 18a, 18a of the guides 18, 18, both sides 1d, 1
d is guided without a gap.

Therefore, when the door 5 is opened and closed, the other end of the check plate 1 does not swing more than necessary in the width direction, and the check plate 1 does not interfere with the peripheral edge of the through hole 7a of the case 7. Thus, it is possible to reliably prevent the interference sound with the case 7 due to the deflection of the check plate 1.

Also, the guide 1 may be displaced due to the variation in component accuracy.
When the inner width P of each of the tops 18b and 18b of the upper and lower parts 8 and 18 is reduced or the outer width Q of the check plate 1 is increased, as shown in FIG. 3, the respective tops 18b and 18b are formed by the cavities 18c and 18c. Since the bending is performed, the load due to the contact hardly increases, and the opening / closing operation feeling of the door 5 is improved. Further, the tops 18b, 18b of the guides 18, 18
Can be prevented, and the durability of the guides 18 is improved.

Furthermore, since only the cavities 18c, 18c are formed in the rising portions 18a, 18a of the guides 18, 18, the structure is simple, the number of parts is not increased, the cost is low, and the existing door checker is used. Also, Guide 18,
It can be adopted simply by replacing 18.

The guide 18 of the above embodiment is of a type in which the upper and lower surfaces of the check plate 1 are supported by trapezoidal top surfaces 18d. However, as shown in FIG. The roller guide may be a roller guide.

Further, in each of the above embodiments, the cavities 18c, 18c are formed in the rising portions 18a, 18a of the guide 18, but as shown in FIG. And the fully open position G
d, 1d, a projecting portion 1e projecting laterally is formed, a cavity 1f is formed in the projecting portion 1e, and the projecting portion 1e can be elastically deformed (bent) in the width direction by the cavity 1f. It is good.

[0020]

As is apparent from the above description, the door checker for a vehicle according to the present invention is provided with a pair of guides housed in a door case or a protrusion at a half-open position and a full-open position on both sides of a check plate. Either one of which has a cavity that is a hole in the vertical direction and forms an elastic portion that can be elastically deformed in the width direction to reduce the gap between the check plate and the rising portion of the guide. Therefore, the check plate does not rattle in the width direction and does not interfere with the peripheral edge of the through hole of the case, so that no interference noise is generated. In addition, interference noise can be easily prevented even by replacing the guide with an existing door checker.

Further, the bending of the elastic portion having a cavity, which is a hole in the vertical direction, formed at one of the protruding portions at the half-open position and the full-open position on the rising portion of the guide or on both sides of the check plate, allows the precision of the component to be improved. Irrespective of the variation, the load due to contact is unlikely to increase, so that the opening / closing operation feeling of the door is improved, the wear of the rising portion of the guide can be prevented, and the durability is improved.
