[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an emergency lock device for a vehicle door.

[Conventional technology]

Conventionally, in a vehicle having a sliding door that slides along the side of the vehicle body, an upper arm 1 and a lower arm 2 are disposed at the upper and lower ends of the sliding door D, as shown in FIGS. 1 and 2. The rollers 3 and 4 of the upper arm 1 and the lower arm 2 are slidably mounted on slide rails 5 and 6 disposed at the upper and lower parts of the vehicle interior, respectively, and are disposed at the center of the rear edge of the slide door D. A center roller is slidably mounted on a center slide rail 10 disposed on the outer panel of the vehicle body, thereby supporting the slide door D so as to be slidable along the side portion of the vehicle body. On the other hand, on the rear edge Dr of the sliding door D, there is a door lock device L that engages with a striker fixed to the rear edge Br of the vehicle door opening facing the rear edge Dr.
are arranged, and the front edge Df of the sliding door D and the upper and lower parts of the front edge Bf of the vehicle door opening facing this front edge Df are arranged as shown in FIGS. 3 and 4. A dovetail mail 8 and a dovetail female 9 were respectively provided to fix the front side of the slide door D and to position the slide door D in the front and back direction when the slide door D was closed (Nitsun Service Bulletin No. 427). (CA-9) Showa era
(Refer to the introduction of the Nitsusan Kiyaraban Homey E23 model in August 1955).

[Problem that the invention attempts to solve]

However, in the conventional support structure of the sliding door D, the upper and lower ends of the sliding door D are fitted and supported by the arms 1 and 2 and the slide rails 5 and 6, and the rear side of the sliding door D is The edge Dr is supported by the engagement between the door lock device L and the striker, and the front edge Df of the sliding door D is
were supported by fitting support with the dovetails 8 and 9, respectively. Therefore, when a load is applied to the sliding door D toward the interior of the vehicle due to a side collision of the vehicle, the sliding door D deforms and the tab tail mail 8 becomes attached to the tab. The problem was that the tail female 9 escaped in the sliding direction of the door, causing the two to become disengaged and the front side of the sliding door to be greatly deformed.

As a means to solve this problem, it may be possible to reinforce the door opening edge on the side of the vehicle body and the sliding door D itself using reinforcing materials, but this method not only increases the vehicle weight, but also increases the weight of the vehicle.
This method not only increases costs but also reduces the interior space of the vehicle due to the increased width of the sliding door D, and has the disadvantage that it cannot be adopted immediately.

This invention was devised in view of the current situation, and its purpose is to prevent loads such as vehicle side collisions from being applied to the sliding door without reinforcing the door opening edge on the side of the vehicle body and the sliding door itself. It is an object of the present invention to provide an emergency lock device for a vehicle door that can prevent deformation of a sliding door as much as possible even if the sliding door is operated.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention has been developed to provide a door lock device on one side edge of a sliding door for a vehicle, and an opening edge of the vehicle body door opposite to this one side edge. In an emergency lock device for a vehicle door, a lock striker is attached to the lock striker on the other side, and a latch member that engages with the lock striker when the door is closed is attached to the other side. one latch member is composed of a plate forming the surface of the other side, and the lock striker is inserted into this plate in the door sliding direction. A hole and a slit portion which is provided continuously on the side of the insertion hole and allows the shaft portion of the lock striker to move when the sliding door is displaced, and when the sliding door is closed, the lock striker is inserted into the insertion hole of the latch member. is inserted to position the locking part of the lock striker ahead of the insertion hole, and when the door is displaced, the shaft part of the lock striker moves within the slit part, and the locking part locks with the peripheral edge of the back surface of the slit part. The means is an emergency lock device for a vehicle door that prevents the lock striker from coming off in the sliding direction.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

5 to 7 show an emergency lock device according to a first embodiment of this invention, and show a sliding door D to which this emergency lock device is applied.
Although not shown, is supported so as to be able to slide along the side of the vehicle body via upper, middle, and lower slide rails, as well as the conventional sliding door D described above, and is supported on the rear side of the sliding door D. A door locking device is arranged on the edge, which engages the striker when the door is closed.

A lock striker 11 is attached to the front edge Df of the slide door D supported in this manner. This lock striker 11 has a base 12 fixed to the front edge Df of the sliding door D with a bolt/nut B, and a base 12 fixed to the front edge Df of the sliding door D.
It is composed of a pair of upper and lower shaft parts 13a, 13b protruding from the base 12 toward the front edge Bf of the vehicle door opening facing Df, and a locking part 14 connecting the tips of these shaft parts 13a, 13b, Shaft 1
3a, 13b and the locking portion 14 form a U-shaped cross section.

On the other hand, an embossed recess 15 is formed on the front edge Bf of the vehicle door opening, which faces the mounting portion of the lock striker 11.
A reinforcement 16 is welded and fixed to the back surface of the recess 15, and a latch member 17 is fixed to the opening side of the recess 15 with a bolt nut (not shown).

This latch member 17 is composed of a substantially diamond-shaped plate 18 that closes the recess 15 and forms a flat surface. 14 is freely inserted in the door sliding direction, and the shaft portion 13 of the lock striker 11 communicates from the upper and lower parts of the insertion hole 19 in both left and right directions, and when the sliding door D is displaced, the shaft portion 13 of the lock striker 11
Slit portion 20 in which a and 13b are movable, respectively.
a, 20b and 21a, 21b are established, respectively.

Therefore, when closing the sliding door D, the lock striker 11 is inserted into the insertion hole 1 of the latch member 17.
9, and the locking part 14 is inserted into the insertion hole 19.
While the sliding door D is located in the recess 15 further forward, in this state, a deforming load acts on the sliding door D toward the passenger compartment due to a vehicle side collision, for example, and the sliding door D is displaced toward the passenger compartment. As shown in Fig. 7, the lock striker 11
The shaft portions 13a, 13b of the latch member 17 move laterally from the insertion hole 19 into the slit portions 20a, 20b. Then, due to the displacement of the sliding door D, the lock striker 11 receives a tensile force (F) in the backward sliding direction, but the locking portion 14 of the lock striker 11 locks with the peripheral edge of the back surface of the slit portions 20a and 20b. Therefore, the lock striker 11 is prevented from detaching from the latch member 17. In this way, in the event of a vehicle body collision, even the front edge Df of the sliding door D will remain engaged with the vehicle body, so the sliding door D
There is no problem if the slide door D comes off, and the amount of deformation of the sliding door D can be kept small. Furthermore, since the upper and lower sides as well as the front and back of the sliding door D are supported when the door is deformed, the deformation load can be dispersed, and the durability of the slide rail, door lock device, etc. can also be improved.

Such an effect also exists when the luggage stacked in the vehicle interior collapses and a deforming load is applied to the sliding door D in the direction outside the vehicle. 17 into the slit portions 21a and 21b.

FIGS. 8 and 9 show an emergency lock device according to a second embodiment of the invention, and the emergency lock device according to this embodiment has a lock striker 23' and a latch member 24'. The structure and operation are the same as in the first embodiment except for the change in the shape of the hole.

That is, in this embodiment, the lock striker 23 has a shaft portion 25 projecting toward the latch member 24, and a circular lock formed at the tip of the shaft portion 25 and having a diameter larger than that of the shaft portion 25. Part 26
A nut N is screwed into a threaded portion 27 carved at the rear end of the shaft portion 25. On the other hand, the latch member 24 has an insertion hole 28 having a larger diameter than the locking portion 26 of the lock striker 23 in the center of the same plate 18 as in the previous embodiment, and the insertion hole 28 is continuous in both left and right directions. opened, and the above-mentioned shaft part 25
Slit portions 29a, 2 whose diameter is somewhat larger than the shaft diameter of
9b.

When the sliding door is closed, the lock striker 23 engages the latch member 24 in the same way as in the first embodiment.
The locking portion 26 enters the insertion hole 28 of the insertion hole 2.
However, when an external force that deforms the sliding door D is applied due to a side collision or the like, the shaft portion 25 moves into the slit portion 29a due to the displacement of the sliding door D. In addition, since the locking portion 26 locks with the periphery of the back surface of the slit portion 29a of the latch member 24 against the escape of the lock striker 23 in the sliding direction, the engaged state of both is ensured and the sliding door D is removed. can be prevented.

In the above embodiment, the lock strikers 11, 23 are arranged on the sliding door D, and the latch members 17, 24 are arranged on the vehicle body side. On the vehicle body side, the latch members 17 and 24 may be provided on the sliding door D side.

Further, in this invention, it goes without saying that the emergency lock device may be used in combination with the dovetail.

[Effect of idea]

By including the above configuration, this invention can reliably prevent the lock striker from slipping out of the latch member in the sliding direction in the event of a vehicle side collision, etc., without increasing the weight of the vehicle. The door is prevented from coming off the vehicle body, and deformation of the sliding door can be suppressed as much as possible. Moreover, the load applied to the support members of the sliding door during the deformation is dispersed, and the durability of each support member is also improved.
