Description

[0001]
[Technical field to which the invention belongs]
TECHNICAL FIELD The present invention relates to a seal structure that is attached to the periphery of an opening that opens and closes a door glass of an automobile door and seals between the door glass when the door glass is closed, and in particular, when the door glass is closed, The present invention relates to a seal structure including a sensor that detects when a foreign object is sandwiched between the periphery of the opening.
[0002]
[Prior art]
The seal structure that seals between the door glass when the door glass is closed and is attached to the periphery of the opening that opens and closes the door glass of an automobile door. When a foreign object is caught between the two, attach a sensor to detect this, and when the sensor detects a foreign object, stop or reverse rotate the motor of the regulator device to stop or lower the door glass in the middle of ascent Is known.
[0003]
An example of a seal structure for a door glass provided with such a sensor is disclosed in Japanese Patent Laid-Open No. 10-1000067. As shown in FIG. 1, this seal structure is pushed into the door glass 3 when the attachment base 2 attached to the retainer 1 attached to the periphery of the opening of the door and the door glass 3 are closed, and the door glass 3. A dovetail-like fitting groove 5 is formed between the mounting base 2 and the sealing part 4 and the sensor 6 is pushed into the fitting groove and attached. ing.
[0004]
[Problems to be solved by the invention]
In the conventional seal structure shown in FIG. 1, the sensor 6 is attached by being pushed into the fitting groove 5 from the direction of the arrow in the figure (inserting from the end of the fitting groove has a high frictional resistance and is difficult). .
[0005]
The present invention can be easily installed by pushing along the fitting groove or inserting it from the end of the fitting groove according to the situation and conditions, and when the sensor has to be replaced due to failure or the like. It is an object of the present invention to provide a door glass seal structure that can be replaced only partially.
[0006]
[Means for solving problems]
The invention according to claim 1 is attached to the periphery of the opening portion where the door glass 3 of the automobile door opens and closes. When the door glass 3 is closed, the door glass 3 is sealed and the door glass 3 is closed. In this case, when a foreign object is sandwiched between the door glass 3 and the peripheral edge of the opening of the door, it is a seal structure to which a sensor 12 for detecting this is attached, and the fitting grooves 11 and 23 in which the sensor 12 is mounted. If, mounted push the groove edge of the fitting groove 11, 23 equipped with a sensor 12, the sensor 12 to block the groove 11, 23 have a cap 13 separate, to the sensor 12 in the cap 13 it is intended to have the pressing portion 13.
[0007]
In the present invention, the sensor is attached to the fitting groove by pushing the sensor along the fitting groove or by inserting the sensor from the end of the fitting groove, and after the sensor is attached, the cap is pushed into the fitting groove. Attach with. This prevents the sensor from coming off.
[0008]
The sensor only needs to be mounted in the fitting groove, and it does not need to be configured so that it does not come out of the fitting groove. Therefore, the sensor can be made the minimum size and the contact area on the inner surface of the fitting groove should be reduced. Therefore, when pushing into the fitting groove, pushing can be performed easily. Also, when inserting from the end of the fitting groove, if the contact area with the inner surface of the fitting groove is small, the insertion becomes easy.
When the sensor has to be replaced due to a failure or the like, only the sensor is replaced, and the cap for preventing the sensor from being removed can be reused.
[0009]
Cap used in the present invention, minimal, but as long as it has been mounted in the fitting groove function for retaining the sensor, and preferably pressing the sensor at the pressing portion during attachment to the fitting groove that It is desirable to restrain the movement. It is also desirable that the cap be made of an elastic material or structure that is easy to install in the fitting groove and does not easily come out after installation.
[0010]
The invention according to claim 2 is characterized in that, in the invention according to claim 1, the cap has an elastically deformable hook-shaped locking lip fitted and locked to the groove edge.
[0011]
In the invention according to claim 2 , the locking lip is pushed into the fitting groove in a squeezed state. After being pushed in, it is restored and the locking lip is locked to the groove edge to prevent it from coming off. Each of the above inventions can be applied not only to a seal structure of the type shown in FIG. 1 but also to a seal structure such as a glass run attached to a U-shaped sash portion.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 shows an example in which the present invention is applied to a seal structure of the type shown in FIG. 1. In the figure, the same structure as that shown in FIG.
The opening of the fitting groove 11 is narrowed, and a flat sensor 12 is mounted in the fitting groove. The cap 13 is shaped like a “mountain” in cross section, and has a pressing portion 13a that holds the sensor 12 in the center and supports it in a fixed state, and hook-like locking lips 13b that lock the groove edges on both sides. For example, it is made of EPDM solid rubber, TPE (thermoplastic elastomer) or the like.
[0013]
In this embodiment, the sensor 12 is mounted by being pushed along the fitting groove 11 or inserted from the groove end of the fitting groove 11. After the sensor is mounted, the locking lips 13b on both sides of the cap are pressed from both sides, and the locking lips 13b are squeezed from the groove edge to lock each locking lip 13b to the groove edge. FIG. 2 shows the attached state.
[0014]
FIG. 3 shows an example in which the present invention is applied to a glass run type seal structure. A glass run 16 attached to a door sash 15 having a substantially U-shaped cross section includes a base portion 17 and side walls 18a on both sides of the base portion. , 18b, formed on the outside of each side wall 18a, 18b, and formed on the inside of the side walls 18a, 18b and protective lips 19a, 19b enclosing the flanges 15a, 15b of the door sash 15, and when the door glass 3 is closed, It consists of seal lips 21a and 21b that seal between the door glass 3 and projecting pieces 22a and 22b that protrude from both sides of the base portion 17 and prevent the glass run 16 from coming off. A fitting groove 23 having the same structure as the fitting groove 11 is formed, and the sensor 12 is mounted in the fitting groove 23 as described above, and the cap 13 is similarly mounted on the groove edge. It is mounted Te.
[0015]
【The invention's effect】
According to the first aspect of the invention, since the sensor does not need to have a function of preventing the fitting groove from coming off, the size can be reduced, the contact area in the fitting groove can be reduced, and the structure can be simplified. Therefore, pushing into the fitting groove and insertion from the fitting groove end are facilitated, and mounting can be performed from any direction. When it is necessary to replace the sensor due to a failure or the like, only the sensor needs to be replaced, and the cap can be reused.
[0016]
In the invention concerning Claim 2, it becomes easy to mount | wear with a cap in a fitting groove | channel, and it does not come out easily after mounting | wearing.
