Abstract

PURPOSE:To prevent a lock from its improper action caused by collision or the like of a vehicle, by extending constitutional parts of a lock main unit in the external wall direction of a door for the vehicle and folding this extending part in its point end to form a protecting plate which encloses the constitutional parts of the lock main unit. CONSTITUTION:A lock main unit 4 of triple construction, comprising a metallic cover plate 5, synthetic resin made body 6 and a metallic back plate 7, is provided between internal and external walls 2, 3 of a door 1 for a vehicle. And the lock main unit 4, which rotatably mounts an open lever 8 or the like to an axis 9 in a side of the metallic back plate 7 further protrudes one end of the open lever 8 to a side of the external wall 3 from the lock main unit 4, rotatably supports a rod 11 in its point end to this protruding part 10. In this constitution, an extending part 16 is formed by extending the metallic cover plate 5 in the direction of the external wall 3. And a protecting plate 17, which encloses the protruding part 10 and the rod 11, is formed by folding the point end of the extending part 16. In this way, the external wall 3, recessed by collision or the like, is enabled to be stopped.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a protective locking device for a vehicle.

(Prior art) Conventionally, a lock body 4 having a triple structure of a metal cover plate 5, a synthetic resin body 6, and a metal back plate 7 is provided between the inner wall 2 and the outer wall 3 of a vehicle track l, and a metal back plate is provided. Plate 7 biased t < - (3rd prize M 9t,
, one end of the open lever 8 protrudes from the lock body 4 toward the outer wall 3 to form a protrusion 10, and the protrusion 10 has a loft 1.
One in which the tip of 1 is fixed with a shaft is known.

(Problems to be Solved by the Invention) As shown in FIG. 1, when another vehicle collides with the outer wall 3 of the door 1, the outer wall dents and sinks into the protrusion 10, causing the protrusion 10 to collapse. It may stop moving. If this happens, the door l may become unbalanced, or the door may become unlocked and open.

(Means for Solving the Problem) Therefore, the present invention extends one or both of the metal cover plate 5 and the metal back plate 7 toward the outer wall 3 of the door l to form the extension part 16. Then, bend the tip of the extension part 16 to remove the lever protrusion 10 and the rod l.
This is a protective locking device for a vehicle in which a protective plate (17) surrounding the vehicle is formed.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 2 denotes an inner wall of a vehicle door l, numeral 3 an outer wall thereof, and 4 a lock body mounted within the vehicle door l. As is well known, the lock body 4 has a triple structure consisting of a metal cover plate 5, a synthetic resin body 6, and a metal back plate 7, and an open lever 8, etc. is pivoted 9 on the metal back plate 7 side. . One end of the open lever 8 protrudes from the lock body 4 toward the outer wall 3 to form a protrusion 10, and the tip of a rod 11 or the like is pivotally fixed to the protrusion 10. 12 is a striker insertion window formed in the inner wall 2, n is a striker insertion groove formed in the lock body 4, 14 is a latch, and 15 is a shaft of the latch.

In FIG. 2, the metal cover plate 5 is extended toward the outer wall 3 to form an extension 16, and the tip of the extension 16 is bent to protect the protrusion 10 and the rod 0. Play) 17 was formed.

In FIG. 4, the metal back plate 7 is extended toward the outer wall 3 to form an extension 16, and the tip of the extension 16 is bent to form a protection plate 17 that surrounds the protrusion 10 and the rod 11. It was formed.

In FIG. 5, the metal cover plate 5 is extended toward the outer wall 3 to form an extension 16, and the tip of the extension 16 is bent to form a protection plate 17 that surrounds the protrusion 1110 and the rod 11. In addition, the metal back plate 7 is extended toward the outer wall 3 to form an extension s16, and the tip of the extension 16 is bent to form a protective plate) 17.
form.

This is a combination of both protective plays) 17.

In FIG. 6, when extending the metal cover plate 5 toward the outer wall 3 to form an extension @tS, an extension part 16 is formed as a separate member.

In FIG. 7, the metal cover plate 5 is extended toward the outer wall 3 to form an extension portion 16.

An engagement recess 4 is formed at the tip of the extension 16, the metal back plate 7 is extended toward the outer wall 3 to form the extension 16, and the tip of the extension 16 is bent to form a protection plate. 17, and an engaging convex portion that evenly engages with the engaging concave portion is formed at the tip of the protective plate 17, and the protective plate 17 is engaged and joined.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described structure, even if the outer wall 3 is deformed and dented as shown in FIG. It works normally. Therefore, lock operation failure due to a collision or the like is prevented.

(Effects) Conventionally, a lock body 4 with a triple structure of a metal cover plate 5, a synthetic resin body 6, and a metal back plate 7 is provided between the inner wall 2 and the outer wall 3 of a vehicle door l, An open lever 8 or the like is pivoted 9 on the 7 side, one end of the open lever 8 protrudes from the lock body 4 toward the outer wall 3 to form a protrusion 10, and the tip of a rod 11 is pivoted to the protrusion 10. Things are publicly known.

In the known type, when another vehicle collides with the outer wall 3 of the door 1, the outer wall dents and sinks into the protrusion 10, as shown in FIG. 1, so that the protrusion 10 may not move. When this happens, the door l may become unable to open, or may be unlocked and opened.

However, in the present invention, one or both of the metal cover plate 5 and the metal back plate 7 is extended in the direction of the outer wall 3 of the door l to form an extension part 16, and the tip of the extension part 16 is Since this is a locking device with protection for a vehicle in which a protective plate 17 is bent to surround the lever protrusion 10 and the rod U, when a car or the like collides with the outer wall 3, the outer wall 3 is deformed and the third Even if it is recessed as shown in the figure, the recessed outer wall 3 will stop at the protective plate 17, and the protruding part l
O operates normally. Therefore, there is an effect of preventing lock operation failure due to a collision or the like. Further, in the present application, either the metal cover plate 5 or the metal back plate 7 (or both) is extended in the direction of the outer wall 3 to form the extension part 16, and the extension part! Since the protective plate 17 that surrounds the protrusion 10 and the rod 11 is formed by bending the tip of the rod 6, the cost is only the increase in the steel material.
It has almost no effect on cost.
