Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a side door longitudinal restraint device for restraining a side door to a vehicle body.

[Conventional technology]

A roof is attached to the upper part of a typical car body, and the roof is integrated with other parts of the car body to improve the rigidity of the car body.

On the other hand, in automobiles such as open cars with removable roofs, various measures have been taken to ensure the rigidity of the car body. For example, the fifth
In the side door restraint device shown in Fig. 6,
When the door is closed, the door 10 and the vehicle body side are connected by a female 14 including a mail 12 and a collar 15 in addition to a door lock (not shown), whereby the free end side of the door 10 is connected to the vehicle body side. This restraint improves the rigidity of the vehicle body. Therefore, when the door 10 is closed, it is preferable to make the gap d between the mail 12 and the collar 15 as small as possible. For this reason, conventionally, the tapered part 13 formed in the mail 12,
By fitting the tapered fitting hole 17 formed in the collar 15, the gap d can be made as small as possible, and the mail 12 can be closed when the door 10 is opened and closed.
Interference between the movement locus of the tapered portion 13 and the collar 15 is avoided.

However, in the above side door restraint device,
When the relative positions of the mail 12 and the female 14 are separated from their normal positions in the vehicle body width direction due to assembly variations, the gap d between the mail 12 and the collar 15 increases. Furthermore, if the relative positions of the mail 12 and the female 14 approach in the vehicle width direction from their normal positions, the tapered part 13 of the mail 12 and the collar 15 will interfere with each other when the door 10 is opened and closed, making it difficult to open and close the door 10 smoothly. Operation is hindered. Furthermore, when the opening and closing operations of the door 10 are repeated in this state, the collar 15 is worn out due to interference between the tapered part 13 of the mail 12 and the collar 15, and the diameter of the fitting hole 17 is expanded. As a result, the gap d between the tapered portion 13 of the mail 12 and the collar 15 becomes larger, and the effect of restraining the door 10 on the vehicle body side is reduced. Also, mail 12 and female 14
Similarly to the above, when the relative position of the mail 12 moves away from or approaches the normal position in the longitudinal direction of the vehicle body, the tapered part 13 of the mail 12 and the collar 15
will interfere.

If the relative position of the mail 12 and the female 14 deviates from the normal position as described above, the above-mentioned problems will occur, so the assembly work will be delicate.
There is a problem that assembly workability is not good. Also,
Even if the installed state of the door 10 changes during the course of use, it is necessary to adjust the relative positions of the mail 12 and the female 14, and this work also has the problem of being relatively time-consuming.

[Problem that the invention attempts to solve]

The present invention takes the above facts into consideration and aims to provide a side door longitudinal restraint device that does not require relative position adjustment between the mail and the female.

[Means for solving problems]

In the side door longitudinal restraint device according to the present invention, a mail is attached to either the side door or the vehicle body and has a tapered portion at its tip, and the tapered portion of the mail is attached to the other side. A pair of fitted moving members and a female equipped with urging means for individually urging these moving members in the width direction of the vehicle body are combined.

[Effect]

In the side door longitudinal restraint device with the above configuration,
The tapered part of the mail is pressed and held between a pair of moving members biased by a biasing means, and the mail is fitted into the female.

When the relative positions of the mail and the female shift, each of the pair of moving members is individually moved against the biasing force according to the position of the mail when the door is closed;
Always press and hold the tapered part of the mail in the proper state.

[Configuration of Example]

1 to 4 show an embodiment of a side door longitudinal restraint device according to the present invention.

FIG. 1 schematically shows an automobile in which an embodiment of the present invention is used.

A door 18 is attached to the side of the vehicle so that it can be opened and closed by hinge means (not shown). As shown in FIG. 2, this door 18 is formed from a door outer panel 20 and a door inner panel 22. On the rear side of the door 18, a mail 24 is fixed to the outer surface of a door inner panel 22 via bolts (not shown). The tip of this mail 24 faces inside the vehicle body. A tapered portion 26 tapered toward the inside of the vehicle body is formed at this tip.

Further, a quarter panel 28 is disposed on the side of the vehicle, adjacent to the opening of the door 18, and forming the rear outer surface of the vehicle body. A quarter inner panel 30 is disposed inside the quarter panel 28 and forms the rear inner surface of the vehicle body. This quarter inner panel 30 and quarter panel 2
8 are fixed to each other, and a space 32 is formed between the quarter inner panel 30 and the quarter panel 28.

A female 34 is accommodated in this space 32. As shown in FIG. 3, this female 34 includes a female body 36, a pair of slide pieces 37 and 38, and a pair of compression coil springs 40.
, a pair of guide rods 42 , and a back plate 44 .

The female body 36 has flanges 46 and 48 formed at both ends thereof.
An opening 50 is formed on the side. This opening 5
0 communicates with a housing hole 52 that opens on the flange portion 48 side. A back plate 44 is fixed to the flange portion 48 via screws 54, and one end of the accommodation hole 52 is closed. A pair of guide rods 42 are disposed in the receiving hole 52 .
One end of the pair of guide rods 42 is locked in a hole 44A formed in the back plate 44, and the other end is locked in a hole 36A formed in the female body 36 on the flange portion 46 side. Slide pieces 37 and 38, which are moving members, are slidably attached to the intermediate portions of the pair of guide rods 42. The slide pieces 37 and 38 can also slide on the side wall of the accommodation hole 52. The surfaces of the slide pieces 37 and 38 that face each other are formed as inclined surfaces, and both inclined surfaces are formed on the flange portion 4.
They are gradually spaced apart toward the 6th side. A pair of compression coil springs 40 are wound around the intermediate portions of the pair of guide rods 42 between the slide pieces 37, 38 and the back plate 44. As a result, the slide pieces 37 and 38 are biased toward the opposite side of the back plate 44 by the compression coil spring 40.

The female 34 thus configured has a flange portion 46 that is in close contact with a stopper reinforcement 56 fixed to the quarter panel 28, and is fixed to the quarter panel 28 via bolts (not shown). This female 34 is a mounting hole 5 formed in the quarter inner panel 30.
It is said that it can be removed from 7. In the female 34, when the door 18 is closed, the tapered portion 26 of the female 24 attached to the door 18 passes through an opening 58 formed in the quarter panel 28 and the stopper reinforcement 56, and passes through the opening 50. It is adapted to be accommodated inside the accommodation hole 52. In this state, the tapered part 26 of the mail 24 is fitted between the inclined surfaces of the slide pieces 37 and 38 inside the accommodation hole 52, and the slide pieces 37 and 38 are urged by the compression coil spring 40, and the mail 24 The tapered portion 26 of the holder is pressed and clamped.

A weather strip 23 is fixed to the door inner panel 22, and the weather strip 23 is in close contact with the quarter panel 28 when the door 18 is closed.

[Effect of the embodiment]

When the door 18 is open, the mail 24 and the female 34 are not fitted, and each door 1
8 side, it is separated and fixed to the vehicle body side. Therefore, the slide pieces 37 and 38 of the female 34 are as shown by two-dot chain lines in FIG.
It is biased by a compression coil spring 40 and is located at one end of the movement toward the outside of the vehicle body.

When the door 18 is closed, the mail 24 is moved toward the inside of the vehicle along with the movement of the door 18. Due to this movement of the mail 24, the tapered part 26 of the mail 24 passes through the openings 58 and 50, fits between the respective inclined surfaces of the slide pieces 37 and 38, and presses the slide pieces 37 and 38. The pressed slide pieces 37 and 38 are compressed coil springs 40
It is moved toward the back plate 44 against the urging force of. At this time, the slide pieces 37 and 38 are guided by the guide rod 42 and the side wall of the housing hole 52 and moved, and as shown in FIG. It is located approximately at the center of the accommodation hole 52.
The state shown in FIG. 2 is a case where the relative positions of the mail 24 and the female 34 are at the standard position. Therefore, the mail 24 and the female 34 are fitted together without any gap being formed between them, so that movement of the door 18 in the longitudinal direction of the vehicle body is reliably restrained.

When the car body is subjected to vertical force while the car is running, and a force that tries to bend the car body along the longitudinal direction of the car body acts, a large force in the longitudinal direction of the car body acts between the mail 24 and the female 34. . At this time, the tapered part 26 of the mail 24 is connected to the slide piece 3.
7 or 38 in the longitudinal direction of the vehicle body. Since either one of the guide pieces 37, 38 pressed by the tapered portion 26 of the mail 24 is restricted from moving in the longitudinal direction of the vehicle body by the side wall of the accommodation hole 52, the movement of the mail 24 in the longitudinal direction of the vehicle body is restricted. to restrain. As a result, a portion of the vertical force applied to the vehicle body is transmitted to the door 18 via the mail 24. The force transmitted to the door 18 is distributed throughout the vehicle body via a hinge (not shown). On the other hand, the force acting on the female 34 at the same time is transferred to the stopper reinforcement 56 via bolts (not shown).
and distributed throughout the vehicle body. Thereby, the door 18 acts as a means for improving the rigidity of the vehicle body.

As shown in FIG. 4, when the mail 24 is assembled to the female 34 in a state where the door 18 is fully closed and the door 18 is fully closed, the door 18 cannot be closed. At this time, the slide piece 38 is pressed by the tapered portion 26 of the mail 24 and is moved by a distance B against the biasing force of the compression coil spring 40. On the other hand, slide piece 3
7 is the distance C against the biasing force of the compression coil spring 40
, and is positioned offset from the slide piece 38 in the vehicle body width direction. In this state, the door 18 is fully closed. In this case as well, the slide piece 37,
38 presses and clamps the tapered portion 26 of the mail 24 in a proper state, and restricts movement of the mail 24 in the longitudinal direction of the vehicle body. Also, contrary to the above, even if the mail 24 is assembled to the female 34 from the standard position toward the rear of the vehicle body, when the door 18 is closed, the slide piece 37,
The magnitude of the moving distance of 38 is opposite to that in the above case. )
The slide pieces 37 and 38 press and hold the tapered portion 26 of the mail 24 in a proper state, and restrain the movement of the mail 24 in the longitudinal direction of the vehicle body.

When the mail 24 is assembled to the female 34 with the door 18 fully closed and the door 18 moved away from or close to the standard position in the vehicle width direction, the door 1
When the mail 8 is closed, the slide pieces 37 and 38 are pressed by the tapered portion 26 of the mail 24 and moved. In this case, the slide pieces 37 and 38 are moved the same distance, and when the door 18 is fully closed, they are separated from the standard position with the mail 24 in the vehicle width direction. As a result, the slide pieces 37 and 38 press and clamp the tapered portion 26 of the mail 24 in an appropriate state, and restrain the movement of the mail 24 in the longitudinal direction of the vehicle body.

If the installed state of the door 18 changes during use, the relative position between the door 18 and the vehicle body will change. Along with this, the relative positions of the mail 24 and the female 34 also change. In this case as well, when the door 18 is closed, the slide pieces 37 and 38 are moved as described above to press and clamp the tapered portion 26 of the mail 24 in an appropriate state, thereby restraining the movement of the mail 24 in the longitudinal direction of the vehicle body.

As described above, in this embodiment, even if the relative positions of the mail 24 and the female 34 are deviated from the standard position when the door 18 is closed, or the relative positions change during use, the door 18
When closed, the mail 24 and the female 34 are fitted with the slide pieces 37 and 38 pressing and holding the tapered portion 26 of the mail 24 in an appropriate state. Therefore, Mail 24 and Female 34
Since the door 18 is fitted without any gap being formed between the door 18 and the vehicle body, the door 18 can be securely secured to the vehicle body. Furthermore, when the door 18 is opened and closed, the slide pieces 37 and 38 are moved following the movement of the mail 24, so the slide pieces 37 and 38 and the tapered portion 26 of the mail 24 do not get caught.
The door 18 can be opened and closed smoothly. Therefore, during assembly, there is no need to adjust the relative positions of the mail 24 and the female 34, so work efficiency can be improved, and no adjustment is required after assembly. Further, when the door 18 is opened and closed, the slide pieces 37 and 38 that fit into the tapered part 26 of the mail 24 when the door 18 is closed are slid on the female body 36, and are also slid on the tapered part 26 of the mail 24. Since there is no tapered part 26 of mail 24 and slide piece 3
The inclined surfaces 7 and 38 are not worn away as in the case of the tapered portion 13 and collar 15 of the conventional mail 12. Furthermore, in the process of use, the female body 3
Even if the slide pieces 37 and 38 are worn out, when the door 18 is closed, the slide pieces 37 and 38 are worn out.
38 is biased by a compression coil spring 40 and slides on the female body 36.
Since no gap is formed between the two, the tapered part 26 of the mail 24 is pressed and clamped in an appropriate state, and movement of the mail 24 in the longitudinal direction of the vehicle body is restrained. Therefore, since the door 18 can be reliably restrained to the vehicle body side, there is no need to replace the worn slide pieces 37, 38 and the female body 36.

In this embodiment, the mail 24 and the female 34 are fixed to the door 18 side and the vehicle body, respectively, but the present invention is not limited to this. good.

Further, in this embodiment, the slide pieces 37, 3
8 is penetrated by a guide rod 42,
However, the present invention is not limited to this, and the guide rod 42 may be replaced with a guide plate or a slide groove that slidably fits with the slide pieces 37, 38, and the slide pieces 37, 38 may be slid on the guide plate or guide groove. The structure may be as follows.

Furthermore, in this embodiment, the slide piece 37,
38 is biased by a compression coil spring 40, but the biasing means is not limited to this, and an elastic body such as rubber may also be used.

[Effect of idea]

As explained above, the side door longitudinal direction restraint device according to the present invention has a mail attached to either the side door side or the vehicle body side and having a tapered portion at its tip, and a mail attached to the other side and the mail attached to the other side. A pair of movable members fitted into the tapered portion of the body and a female equipped with biasing means for individually biasing these movable members in the width direction of the vehicle body are combined, so that the relative relationship between the mail and the female is This has the excellent effect of eliminating the need for position adjustment.
