Description

DETAILED DESCRIPTION OF THE INVENTION The present collection relates to an automobile door checking device that eliminates the occurrence of excitement.

As shown in FIG. 1, a door check device generally includes a check member (1) fixed to a door (A), and a check member (1) fixed to a vehicle body (B).
The proximal end (6) is pivotally attached to the bracket (2) fixed to the bracket (2) via the fitting part (3), and the distal end (6) side has a check and a hook member (
A check arm (4) that is slidably inserted into the check member (1) and has a protrusion (to) that is clamped in pressure contact with the check member (1).
Therefore, when the door lock is opened and closed around the hinge center (A1), the check arm (4) and the check member (1) move relative to each other, and the protruding part moves against the check member (1).
1"), the check arm (4) slides in the longitudinal direction of the check arm (4), so the shape of the raised portion (to) performs a rounding check on the sliding resistance.

In the conventional automobile door checking device, when this checking operation is performed, an abnormal noise, which is a collision sound, is generated at the fitting portion (3) to which the check arm (4) is pivotally connected, which is unpleasant. This is because, as shown in FIGS. 2 and 3, in the conventional door check device, the mounting portion c11 of the mounting bracket (2) and the base end I are connected to the pivot pin (
5), and since they are metal members, there must be a slight gap between the movable parts, so the check member (1) moves to the right as shown in Figure 2. , the slider in, a which is suppressed by the elastic material Qa, I and K.
When n tries to move to a high place on the raised part 1atts of the check arm (4), the check arm (4) is moved due to the resistance.
4) is placed in the figure and pulled to the right, and the base end Qi) of the pivot pin (5) and check arm (4),! There is a pivot bin (
A minute gap (t1) (↑2) is created on the right side of

occurs. 9. As shown in Figure 3, check the check member (
The sliders α1) and (11) of 1) are connected to the check arm (4).
) Check arm (4) at the end of the ridge-1 (to)
If the check arm (4) is located on an inclined surface that slopes downward so that the end of the check arm (4) is pushed to the left in the figure, contrary to Fig. Minute gaps II (14), (15), and (16) are generated on the side. In this way, one minute gap is rounded alternately on the opposite side, and depending on the position of the check arm (4), the position of the minute gap is suddenly reversed, and at that time, the metal comrades are centered and different. Something that generates sound.

This poison was devised by focusing on the above-mentioned problem, and aims to provide an automobile door check device that eliminates the generation of abnormal noise by eliminating the gap between the movable parts.

II version Hereinafter, this Jinqin will be explained based on the illustrated embodiment.

Note that the same parts as in the conventional example are given the same reference numerals.

FIG. 4 to FIG. 7 show an example of the main part.

The check member (1) is fixed to the door holder, holds the protrusion -1Qs of the 4 check arms (4) inside, and is made of elastic material U.
Nine sliders (11), (1
1).

The check arm (4) is inserted through the check member (1), is provided with a stopper having a buffer at its tip, and has a proximal end that is connected to the fitting part (3) and the mounting part of the mounting bracket (2). It is pivoted to the a force.

The fitting part (3) is shown in FIG. 7, and the proximal end of the check arm (4) forms a bifurcated part consisting of one side a,
It is arranged so as to clamp the deforming part Q1 of the mounting bracket (2). Husband holes (461), (47a), and CI are drilled in the forked part and the attachment part a. −
A square chamfer is formed in the fitting hole (46m) on one side, and a four-chamfer part (491m) is formed in the fitting hole (47) on the other side. ) is formed symmetrically and rounded to ensure compatibility, so at least one piece IIaK is required. Fitted in. Pivot pin (5)
has a large-diameter head 691 shaft ring, and the tip
(Foundation) was established, and there was a part of the hole taper at the base of the shaft (to).
is formed, and this tapered part (end) is in close contact with the chamfered part of one side. The pivot pin (5) fitted from the - side of the fork has a tip (end) and a groove (end) protruding from the other side. The fitting metal (2) of the mounting part (2) of the mounting bracket (2) has a diameter larger than the axis lB@ of the pivot pin (5), and the gap between them and the gap between the two prongs -1@η The width of the pusher (6) is made of elastic material and the fitting hole (6) is made of elastic material.
2) is press-fitted and inserted. As shown in Fig. 5, Push & (6) has a flange at one end and a waist at the middle
It has a cylindrical shape with a slit and a fitting hole (
2) When it is press-fitted, the constriction is corrected and it becomes a straight cylindrical shape. Forked part - pivot pin (5) protruding on the other side
The groove ring of the tip member has a plate spring material (9), and a groove in the middle.
An elastic locking member (7) in which a bulge συ which is longer than the width of the holder is formed, a split hole is bored from the tip end to the bulge I, and a presser part συ is formed at the base. is inserted by fitting the split hole (to) into the groove K, and the bulge I
is engaged with the groove 641K to urge the pivot pin (5) toward the distal end.

According to the automobile door check device having the above configuration,
The two prongs of the check arm (4) and the pivot pin (5) are brought into close contact with each other in the fitting hole (46 and the tapered part), and the elastic locking member (7) is biased in the pressure direction. Because of this, they are connected tightly without any gaps, and there is no round gap between the mounting part (2) of the pivot pin (5) and the mounting bracket (2), and the space between them is filled with the push rod (6).・In this example, the constriction part (to) is formed in the pushy (6), so when it fits and becomes a straight cylinder shape, the elastic force that tries to return to the original shape works effectively. Fit together.

When a force is applied to pull the check arm (4) toward the distal end (due to relative sliding movement between the check member (1) and the check member (1) as the door opens and closes), the connection between the fork and the pivot pin (5) In the meantime, a minute gap is about to be formed on the right side of the pivot pin (5) in FIG. However, one ring of the bifurcated part and the base of the shaft part 6 of the pivot pin (5) fit closely together with the listening part and the taper part (end), and Bin (5)
) is urged and locked toward the tip side by the elastic locking portion (7), so even if a minute gap is formed, the chamfered portion and the tapered portion (end) will not fit tightly. Since the alignment state is maintained, no minute gaps will be created, and conversely, even if a force is applied to the check arm (4) toward the proximal end 1 m, no minute gaps will occur; a minute gap will occur. Since metals will not collide unless there is a check arm (4)
There is no abnormal noise between the two prongs, the pivot, and the mounting pin.

The mounting part (21) of the pivot bin (5) and the mounting bracket (2)
+ between the shaft part 6 and the fitting hole (2), the elastic material (6) is press-fitted into the fitting hole (2) and inserted. Therefore, even if a force in the longitudinal direction is applied to the check arm (4) and a minute gap is created on either side of the pivot pin (5), the push & (6) will elastically follow it. to prevent minute gaps from occurring, and as long as minute gaps do not occur, no abnormal noise will occur. Furthermore, even if a small gap is occasionally generated due to strong force, the pusher (6) acts as a buffer, so no abnormal noise will be generated.

In addition, the two prongs, the mounting part Qυ, and the bushing 6) are press-fitted so that the full width of the two prongs (6) fills the gap width of the nine pieces of the two prongs. , pu'y, to>'s elasticity and buffering action, the proximal end of the check arm (4) (
(c) When a vertical load or vibration is applied to the device, no loud noise is generated.

If the press-fitting force of push & (6) is appropriate, the check arm (4) will swing smoothly.

In this example, since the flange is provided at the upper end of the push arm (6), even if a downward load mainly due to its own weight is applied to the forked part of the check arm (4), it can be stably supported. Can be done.

According to the automobile door door check device related to the present poisoning, the check arm and the pivot pin are designed such that the handle portion and a portion of the taper are closely fitted together, and the check arm and the mounting bracket are closely fitted together. Mori, bullet in the mating part! Because the check arm is equipped with a push rod, even if load changes or shocks are applied to the check arm, the check arm will not rattle, and there will be no abnormal noise caused by shifting. The quality performance of the door check device is good, and the sense of operation and reliability are improved.The check arm and check member may be installed in opposite directions, and the check member may be fixed to the vehicle body. Instead of the base end of the mounting bracket, the mounting portion of the mounting bracket may be formed as a bifurcated portion.
