Description

[Detailed Description of the Invention] The present invention relates to a waterproof structure for opening/closing doors of automobiles.

In the past, rainwater, etc. that entered through the cylinder lock attached to the back door at the rear of an automobile, would infiltrate into the interior of the automobile because no waterproof measures were taken.

FIG. 1 is an explanatory diagram showing the internal structure of the back door at the rear of the automobile, where 1 is a back door consisting of an outer panel 2 and an inner panel 3, and 4 is a cylinder lock body attached to the outer panel 2 of the back door 1. A release lever 6 is attached to a rotatable pivot shaft 5 at the tip thereof.

7 is a hole formed in a predetermined location of the inner plate 2, and 8 is a lock lever.
This bracket 9 is rotatably attached to a bracket 9 fixed to the periphery of the rear lower surface of the hole 7 with a pin 10, and its end portion 8' projects slightly upward into the hole 7.

11 is a vehicle body stationary member consisting of an outer plate 12 and an inner plate 13, and 14 is a striker attached to the inner plate 13 of this vehicle body stationary member 11.

The lock lever 8 is configured to be able to engage and disengage from the striker 14, and is released by engaging the release lever 6 with the lock lever 8.

Conventionally, the release lever 6 and the lock lever 8 were engaged at a position directly above the hole 7.

As a result, rainwater, etc. that entered the back door 1 through the cylinder lock body 4 further traveled through the release lever 6 and fell into the vehicle interior through the hole 7.

In addition, since no waterproofing measures were taken at the opening edge of the hole 7, when rainwater etc. that entered the back door 1 fell onto the inner plate 3, it was transmitted through the inner plate 3 and into the hole. 7, there was a drawback that it could fall into the interior of a car as described above.

This invention is an improvement on the above-mentioned drawbacks.
Rainwater, etc. that entered the back door through the cylinder lock,
It is an object of the present invention to provide a waterproof device for an opening/closing door of an automobile that can completely prevent water from entering the interior of the automobile.

The configuration of the present invention will be explained below with reference to the drawings.

In FIGS. 2 to 4, 21 indicates an outer panel 22 and an inner panel 23.
24 is a hole formed at a predetermined position in the inner plate 23, and 25 is a hole approximately the same size as the hole 24 formed on the upper surface periphery of the opening edge of the hole 24. The weir member 25 is provided with a raised portion 25' on its opening edge to prevent rainwater etc. from entering the hole 24.

26 is a cylinder lock body attached to the outer panel 22 of the back door 21, and 27 is a release lever attached to a rotating shaft 28 at the tip of the cylinder lock body 26, as shown in FIG. It is held at a predetermined position above a side part of a hole 24 formed in an inner plate 23 of 21 so as to hang down and be rotatable.

29 is a retaining portion 29 that protrudes toward the release lever 27 at the upper end.
', which is a lock lever having a hole 24
It is rotatably attached to a bracket 30 fixed to the periphery of the lower surface of the rear side with a pin 31, and its upper end portion protrudes slightly upward into the hole 24, and is supported so that the engaging portion 29' is opposed to the release lever 27. This is what I did.

32 is a vehicle body stationary member consisting of an outer plate 33 and an inner plate 34, and 35 is a striker attached to the inner plate 34 of this vehicle body stationary member 32.

The recess 29'' of the lock lever 29 is removably engaged with the striker 35, and the release lever 29 is rotated about the rotation shaft 28 to release the engagement.
This is accomplished by engaging the protruding retaining portion 29' of the lock lever 29, rotating the lock lever 29 about the pin 31, and removing the recess 29'' from the striker 35.

The engagement position between the release lever 27 and the lock lever 29 is such that the release lever 27 is held at a predetermined position above the side portion of the hole 24, and the engagement portion 29' of the lock lever 29 is placed on the release lever 27 side. Since it is protruded, it is not located above the hole 24 but at a position shifted from the vertical direction of the hole 24, that is, a position above the inner plate 23 on the side of the hole 24.

Therefore, rainwater, etc. that has entered the back door 21 from the cylinder lock body 26 flows down the release lever 27, but
This release lever 27 is connected to the back door 21 as described above.
The side part of the hole 24 formed in the inner plate 23 is provided so as to hang upward, and is held so as to engage with the lock lever 29 in the vicinity of this position, so that rainwater etc. that have flowed through the release lever 27 can be removed. As is clear from FIG. 4, the particles do not fall into the hole 24, but instead fall onto the side portion of the hole 24, that is, onto the weir member 25.

This fallen rainwater, etc. is removed from the weir member 25 by the raised portion 25'.
Since it is provided with a hole 24, it cannot penetrate into the hole 24,
Therefore, the water is discharged to the outside through the water drain hole 36 provided at the lower end of the back door 21 along the inner plate 23.

Therefore, rainwater and the like will not enter the interior of the vehicle.

As described above, the present invention includes a cylinder lock release lever and a lock lever that engages and disengages a striker attached to a stationary member of the vehicle body.
In a structure in which the lock levers are engaged with each other inside the back door, the lock levers are locked together outside the vertical imaginary space of the opening from which the lock lever protrudes, and Since a weir member is attached to the lock lever, rainwater that has entered the back door through the cylinder lock body will drip from the tip of the release lever, but the position is outside the raised part of the weir member, and the lock lever is Entry into the interior of the vehicle through the opening can be completely prevented.
