Further, the wind glass 36 that moves up and down between the weather strips 35 attached to the belt line portion 34 of the door 30 has a channel 37 whose lower portion has a substantially U-shaped cross section as shown in FIG. Is held by. Further, FIG. 9 is a sectional view taken along the line AA of the channel 37 portion of FIG. 8, in which the upper ends of the holding pieces 37a, 27b for holding the window glass 36 with respect to the center line of the window glass 36. A shock-absorbing material 38 made of rubber or a sealing material is provided between the channel 37 and the windshield 36 to protect the windshield from damage.

In the case of an elevating window glass, the channel 37 is connected to an arbitrary elevating mechanism and is operated up and down. However, since the elevating mechanism is outside the scope of the present invention, illustration and description thereof are omitted.

In the door 30 having such a structure, as shown in FIG. 7, when the window glass 36 is lifted to close the window, a thin plate-shaped tool 39, for example, is inserted from the gap between the weather strip 35 and the window glass 36. As you insert it, the same tool 39
Since the tip of the door reaches the door lock 33 after getting over the channel 37 and the door lock 33 can be easily unlocked without using a door key, it has been a problem to be solved from the viewpoint of theft prevention.

The solution is to use channel 40 as shown in Figure 10.
Among the holding pieces 40a, 40b of the above, there is also a structure in which the tip of the holding piece 40b on the vehicle outer side is bent outward at a right angle to form the flange 40c, but even in this case, for example, a tool made of an elastic material. The use of 39 causes a problem that the tip of the tool 39 is deformed and gets over the flange 40c of the channel 40 to enter and reach the door lock 33 to be unlocked.

The present invention has been made to solve the above-mentioned conventional problems, and when the window glass is raised and the window is closed, even if a tool or the like is inserted from the belt line side, the tip of the door cannot cross over the channel and the door is closed. It is an object of the present invention to provide a lock / unlock prevention structure for an automobile door, which can prevent the lock from being unlocked.

(Means for Solving the Problems) In order to solve the above technical problems, the present invention unlocks a door lock with a tool inserted between a windshield and a weather strip on the belt line side of an automobile door. A lock release preventing structure for preventing, wherein a first flange protruding outward from an upper end of an outer holding piece of a channel having a substantially U-shaped cross section for holding the window glass and upward from an end portion of the first flange. A flange portion having a substantially hook-shaped cross section is formed which extends and extends toward the outer weather strip of the belt line portion in a state where the door is closed. The second flange forms a channel for the tool. This is a structure for preventing the unlocking of the automobile door, which is configured so that it cannot be crossed.

(Function) By providing a flange portion with a substantially hook-shaped cross section from the upper end of the holding piece outside the vehicle in the channel, the tip of the tool inserted from the door belt line portion is prevented from entering by the flange portion and gets over the channel. Impossible.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a first embodiment of the present invention, in which an upper end of a holding piece 2a on the outer side of the channel 2 is formed. A first flange 2c is formed by horizontally extending a predetermined length outward, and the tip of the first flange 2c is bent further upward in a substantially vertical shape to form a second flange 2d, which is substantially hook-shaped in cross section. The flange 2b of the
A groove 6 that opens upward between the 2b and the windshield 36
Are formed. Therefore, in this channel 2, the flange 2b is directed to the weather strip 35 outside the door belt line portion 34 in a state where the window glass 36 is lifted and the window is closed, and therefore the window of the belt line portion 34 is directed. Glass 36 and outer weather strip 35
Even if the tool 39 is inserted from between and, the tip of the tool 39 is inserted into the groove portion 6 and abuts against the first flange 2c by the second flange 2d that is bent and formed substantially vertically upward. It is guided by the first flange 2c and moved to the second flange 2d side, and its movement is blocked by the second flange 2d. Therefore, the tip of the tool 39 is blocked by the second flange 2d and is prevented from climbing over the channel 2, so that the unlocking of the door lock 33 can be prevented.

Further, FIGS. 2 to 4 show other aspects of the flange, and the channel 3 shown in FIG. 2 has a predetermined angle θ from the upper end of the outer holding piece 3a toward the upper outside. To form a first flange 3c, the tip of which is bent further in a substantially vertical shape to rise upward.
A flange 3b having a substantially hook-shaped cross section is formed by providing 3d, and a groove portion 6 opening upward is formed between the flange 3bs and the window glass 36. Therefore, the tip of the tool 39 inserted from the belt line portion 34 is inserted into the groove portion 6, and the tip is guided by the first flange 3c in the direction of the arrow in the figure, and the tip of the tool 39 is directed outward. Also, the second flange 3d prevents the tool 3 from crossing over the channel 3 and the tool 39 can be reliably prevented from entering.

Further, the channel 4 shown in FIG. 3 is provided with an arcuate flange 4b having a radius R in place of the flange 2b in FIG. 1, and the flange 4b has a base side first flange 4c and a tip rising end portion. The second flange 4d forms an arc-shaped (key-shaped) flange 4b, and a groove 6 that opens upward is formed between the flange 4b and the window glass 36. This channel 4 can likewise reliably prevent the tip of the tool 39 from climbing over.

The channel 5 shown in FIG. 4 is a modified example of the flange 2 in which the curved first flange 5c is used in place of the first flange 2c, and the second flange which rises upward at the end of the first flange 5c. Flange 5d is formed and has a cross-section with a substantially hook shape.
