Description

  The present invention relates to an automotive weather strip provided on, for example, an automotive door, and particularly relates to the technical field of the structure of the end portion of a weather strip having a core material.

  Generally, an automobile is provided with a weather strip for sealing between a door and an opening of a vehicle body. In the weather strip, a metal reinforcing core may be embedded across both ends in the longitudinal direction (see, for example, Patent Documents 1 and 2). As a method of manufacturing a weather strip in which such a core material is embedded, as disclosed in Patent Document 1, the core material and the rubber material are continuously integrated by composite extrusion molding (also referred to as coextrusion molding). There is a method in which a continuous weatherstrip continuous body is obtained by molding and the weatherstrip continuous body is cut to a desired length. In this method, since the core material is continuous in the longitudinal direction, the core material is also cut, and after cutting, the end portion of the core material is exposed from the end portion of the weather strip, and the exposed portion is rusted. It is necessary to treat so as not to corrode. As a treatment method, for example, a method of applying a rust inhibitor or the like to a cut end face is generally known.

  Moreover, in patent document 1, it is trying to remove the part exposed to the external air of the core material after a cutting | disconnection. Moreover, in patent document 2, the whole cutting | disconnection end surface of a weather strip is coat | covered with the coating | coated part which has the predetermined | prescribed thickness formed separately.

Japanese Patent Laid-Open No. 10-1000028 Japanese Patent No. 4492971

  By the way, in the method of applying a rust inhibitor to the cut end face, the work of thick coating so that the core material does not come out is complicated and takes time. Further, uneven coating may occur and rust may occur on the core material. Moreover, when an operator paints by hand, variation will become large and it may be impossible to prevent rust reliably.

  Further, in Patent Document 1, after the weatherstrip continuous material is cut to a desired length, the portion of the core material that is exposed to the outside air is removed, but when removing, a tool is attached to the end portion of the weatherstrip. The operation | work which inserts etc. and cut | disconnects a part of core material etc. is needed, and while this operation | work is complicated, many man-hours are required.

  Moreover, in patent document 2, since the cutting | disconnection end surface of a weather strip is coat | covered with the coating | coated part separately formed, the operation | work which removes a part of core material of patent document 1 and the application | coating process of a rust preventive agent is unnecessary Can be. However, the core material is not exposed only from the cut end surface. For example, when the cutting blade is pressed against the core material, the core material is bent and the end portion of the core material is exposed from the side surface of the weather strip. It is also possible that

  This invention is made | formed in view of this point, The place made into the objective is to prevent a core material from exposing from the terminal part of a weatherstrip, without requiring a complicated operation | work.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a weather strip for an automobile in which a metal core is embedded in an elastic material. The weather strip includes an outer wall portion located outside the vehicle compartment, and a vehicle compartment. The inner wall portion located on the inner side, the outer wall portion and a connecting wall portion for connecting the inner wall portion, and a long weather strip continuous body is cut to a predetermined length, The end portion of the weather strip is provided with a covering portion that covers the cut end surface, and the covering portion is formed to wrap around at least one side surface of the outer wall portion, the inner wall portion, and the connecting wall portion. It has a protruding part.

  According to this configuration, since the cut end surface of the weather strip is covered by the covering portion, when the core material is exposed from the cut end surface, the core material can be covered by the covering portion.

  Further, when the continuous weatherstrip is cut into a predetermined length, for example, when a cutting blade is pressed against the core material, the end of the core material is bent, and the outer wall portion and the inner wall surface are bent. It is conceivable that the part protrudes from at least one side surface of the part and the connecting wall part. In this case, since the covering portion has a protruding portion formed so as to wrap around at least one side surface of the outer wall portion, the inner wall portion, and the connecting wall portion, the end portion of the core member protrudes from the side surface. However, it is possible to cover with the protrusion of the covering portion.

  According to a second invention, in the first invention, the end portion of the core member is bent so as to protrude from a portion between the outer wall portion and the inner wall portion on the side surface of the connection wall portion, The said covering part has the protrusion part formed so that it might wrap around in the part between the said outer wall part and the said inner wall part in the side surface of the said connection wall part.

  According to this structure, since the protrusion part of a coating | coated part wraps around in the part between the outer side wall part and the inner wall part in the side surface of a connection wall part, a coating | coated part does not wrap around outside a weather strip. Thereby, interference with the member arrange | positioned outside a weather strip and a coating | coated part is avoided.

  In a third aspect based on the second aspect, the core material continuously extends to the outer wall portion, the connecting wall portion, and the inner wall portion, and is spaced from each other in the longitudinal direction of the weather strip. A plurality of plate-like portions arranged in the longitudinal direction of the weather strip, and a connecting portion that connects the plate-like portions adjacent to each other in the longitudinal direction of the weather strip. It bends so that it may protrude from the part between a wall part and the said inner wall part.

  According to this configuration, the connecting portion of the core member can be made narrower than the plate-like portion, and the connecting portion is cut and protrudes from the side surface of the connecting wall portion. The projecting range can be narrower than the projecting portion. Thereby, a coating | coated part becomes small.

  According to a fourth aspect of the present invention, there is provided an automotive weather strip in which a metal core is embedded in an elastic material. The weather strip includes an outer wall portion located outside the vehicle compartment, and an inner wall portion located inside the vehicle compartment. And an outer wall portion and a connecting wall portion for connecting the inner wall portion, and a long weather strip continuous body is cut into a predetermined length, and the end portion of the weather strip includes A covering portion covering the cut end surface is provided, and when the weather strip is viewed from the end portion side along the longitudinal direction of the weather strip, a portion overlapping the core material in the covering portion bulges and becomes thick. It is characterized by forming a meat part.

  According to this configuration, since the cutting end surface of the weather strip is covered by the covering portion, the core material can be covered when the core material is exposed from the cutting end surface. Since the part which overlaps with the core material in a coating | cover part swells at this time, the thickness of a coating | coated part becomes partially thick. Thereby, for example, the end of the core material can be reliably covered with the covering portion.

  In addition, since the portion of the covering portion that does not overlap with the core material can be thinned, it is avoided that the end portion of the weather strip is enlarged due to the provision of the covering portion.

  In a fifth aspect based on the fourth aspect, the core member has a plate-like portion that extends continuously to the outer wall portion, the connecting wall portion, and the inner wall portion, and the covering portion is the outer portion. It is formed so that it may extend along the cut end surface of a wall part, the said inner wall part, and the said connection wall part.

  According to this configuration, when the plate-like portion of the core material is continuously provided on the outer wall portion, the connecting wall portion, and the inner wall portion of the weather strip, the plate-like portion is prevented from being exposed from the cut end surface. It becomes possible to do.

  According to the first aspect of the present invention, the end portion of the weather strip is provided with the covering portion that covers the cutting end surface, and the covering portion is formed to wrap around at least one side surface of the outer wall portion, the inner wall portion, and the connecting wall portion. Since the projecting portion is provided, the core material can be prevented from being exposed from the end portion of the weather strip without requiring a complicated operation, and the rust and corrosion of the core material can be suppressed.

  According to the second invention, the end portion of the core member is bent so as to protrude from the portion between the outer wall portion and the inner wall portion on the side surface of the connecting wall portion, and the protruding portion of the covering portion is the connecting wall portion. Since it wraps around the portion between the outer wall portion and the inner wall portion on the side surface, interference between the member disposed outside the weather strip and the covering portion can be avoided.

  According to the third invention, since the connecting portion that connects the plurality of plate-like portions of the core member protrudes from the side surface of the connecting wall portion of the weather strip, the range in which the plate-like portion protrudes is larger. Can be narrowed. Thereby, since a coating | coated part can be reduced in size, interference with another member can be avoided.

  According to the fourth aspect of the invention, since the covering portion covering the cutting end surface is provided at the end portion of the weather strip, and the weather strip is viewed from the end portion side, the portion overlapping the core material in the covering portion is bulged. Thus, the core material can be prevented from being exposed from the end portion of the weather strip without requiring complicated work, and the rust and corrosion of the core material can be suppressed. Moreover, since the part which does not overlap with the core material in a coating | coated part can be thinned, it can avoid that the terminal part of a weather strip enlarges by providing a coating | coated part.

  According to the fifth invention, when the plate-like portion of the core material extends continuously to the outer wall portion, the connecting wall portion, and the inner wall portion of the weather strip, the plate-like portion is exposed from the cut end surface. Can be suppressed.

It becomes possible to do.

  The parting portion-side weather strip 3 is obtained by cutting a long weather strip continuous body 300 as shown in FIG. 7 into a predetermined length. The weather strip continuous body 300 is formed by continuously and integrally molding the core material 35 and a rubber material or a resin material by composite extrusion molding (also referred to as coextrusion molding). FIG. 6 shows the shape of the core material 35 in the shape of a flat plate before being embedded in the parting portion weather strip 3. As shown in FIG. 8, when the weatherstrip continuum 300 is cut by the cutting tool A (blade or the like), the cutting tool A is moved in the direction of the white arrow B in FIG. At this time, the position of the cutting tool A is set so that the cutting tool A cuts the connecting portion 35 b of the core member 35.

  The cutting tool A pushes the connecting portion 35b of the core member 35 in the direction of the white arrow B in FIG. 8, and thereby the end of the cut connecting portion 35b remains bent in the direction of the arrow B. There is. Since the arrow B direction is a direction corresponding to the rear of the parting portion-side weather strip 3, as shown in FIG. 9, the end of the connecting portion 35b is connected to the outer wall portion 32 and the side wall of the connecting wall portion 34. It is bent so as to protrude from the portion between the inner wall portions 33.

  In this embodiment, as shown in FIGS. 4 and 5, a covering portion 31 for covering the cut end surface 3 a (shown in FIG. 9) is provided at the end portion of the parting portion-side weather strip 3. The covering portion 31 can be composed of the above elastic material, and is formed by molding an elastic material using a mold (not shown) and integrated with the cut end surface 3a of the parting portion-side weather strip 3. It is also possible to obtain the covering portion 31 by heating and softening an elastic material that has been previously formed into a sheet shape and closely contacting the cut end surface 3a of the parting portion-side weather strip 3 (sheet forming method).

  The covering portion 31 includes a main body portion 31a extending along end faces of the outer wall portion 32, the inner wall portion 33, and the connecting wall portion 34, and a protruding portion 31b protruding from the main body portion 31a so as to cover the side surface of the connecting wall portion 34. And have. The main body portion 31a is not provided on the protruding plate portion 32a, the outer seal lip portion 32b, and the inner seal lip portion 33a. This is because the core member 35 is not present inside the protruding plate portion 32a, the outer seal lip portion 32b, and the inner seal lip portion 33a, but may be provided.

  The thickness (vertical dimension) T1 (shown in FIG. 5) of the main body 31a can be set to, for example, 2 mm or more and 10 mm or less. By securing a thickness T1 of the main body 31a of 2 mm or more, if a part of the core member 35 protrudes from the cut end surface 3a of the parting portion-side weather strip 3, the protruding portion can be reliably secured by the main body 31a. Can be covered. Further, if the thickness T1 of the main body portion 31a is thicker than 10 mm, the lack of rigidity portion without the core material of the end portion of the parting-side weather strip 3 becomes too long, and the front end portion of the door frame front side portion 103 of the door 100 becomes too long. Since the holding force may be insufficient for the flange-like portion (not shown), it is preferable to set the thickness T1 to 10 mm or less. In the case where the covering portion 31 is formed of an elastic material previously formed into a sheet shape, the thickness T1 of the main body portion 31a can be made thinner, for example, set to 0.3 mm or more and 2.0 mm or less. Can do.

  The protruding portion 31 b of the covering portion 31 is formed so as to go from the cut end surface 3 a of the parting portion-side weather strip 3 to a portion between the outer wall portion 32 and the inner wall portion 33 on the side surface of the connecting wall portion 34. As described above, the end portion of the connecting portion 35b after cutting may protrude from the side surface of the connecting wall portion 34 between the outer wall portion 32 and the inner wall portion 33. The part can be covered with the protruding part 31b.

  Here, the protruding length T2 of the protruding portion 31b is preferably 3 mm or more and 10 mm or less. If T2 is less than 3 mm, there is a high possibility that the end of the connecting portion 35b cannot be completely covered with the protruding portion 31b, which is not preferable. Further, when T2 exceeds 10 mm, the mold material reaches even an unnecessary portion, so that the material cost is improved, and at the time of insertion into the flange-like portion of the front end portion of the door frame front side portion 103 of the door 100, The interference part becomes long, which is not preferable.

  Note that the protruding portion 31 b may be formed not only on the side surface of the connecting wall portion 34 but also on at least one side surface of the outer wall portion 32, the inner wall portion 33, and the connecting wall portion 34. That is, when the connection part 35 b of the core member 35 is embedded in the outer wall part 32 or the inner wall part 33, the end part of the connection part 35 b after cutting is from the side surface of the outer wall part 32 or the inner wall part 33. In this case, the protrusion 31b is preferably formed so as to wrap around the side surfaces of the outer wall 32 and the inner wall 33. That is, in FIG. 4, the protruding portion 31 b is formed so as to wrap around the rear surface of the connecting wall portion 34, but not limited thereto, the protruding portion 31 b is formed so as to wrap around the front surface of the connecting wall portion 34. May be. Similarly, the protruding portion 31b may be formed so as to wrap around either the outer side surface 32 or the inner side wall portion 33 of the vehicle interior side surface or the vehicle interior side surface.

(Effect of Embodiment 1)
As described above, according to the first embodiment, since the cut end surface 3a of the parting portion-side weather strip 3 is covered by the covering portion 31, when the core member 35 is exposed from the cut end surface 3a, The core material 35 can be covered with the covering portion 31. Further, when the continuous weatherstrip 300 is cut into a predetermined length, when the cutting tool A is pressed against the core member 35, the end of the connecting portion 35 b of the core member 35 is bent and connected. It is conceivable that the wall portion 34 protrudes from the side surface, but since the covering portion 31 is formed so as to wrap around the side surface of the connecting wall portion 34, the end portion of the connecting portion 35 b extends from the side surface of the connecting wall portion 34. Even if it protrudes, it can be covered with the covering portion 31. This eliminates the need for applying an anticorrosive agent or cutting the end portion of the core member 35, so that the core member 35 is not exposed from the end portion of the weather strip 3 without requiring a complicated operation. Thus, rust and corrosion of the core material 35 can be suppressed.

  Further, when the end portion of the connecting portion 35b of the core member 35 is bent so as to protrude from a portion between the outer wall portion 32 and the inner wall portion 33 on the side surface of the connecting wall portion 34, the covering portion 31 protrudes. Since the portion 31b wraps around the portion of the side surface of the connecting wall portion 34 between the outer wall portion 32 and the inner wall portion 33, the member disposed outside the parting portion-side weather strip 3 and the protruding portion 31b Interference can be avoided.

  Further, when the core member 35 is cut, the connecting portion 35b having a width smaller than that of the plate-like portion 35a is cut so as to protrude from the side surface of the connecting wall portion 34 of the parting portion-side weather strip 3, so Compared with the case where the portion 35a protrudes, the protruding range can be narrowed. Thereby, since the coating | coated part 31 can be reduced in size, it can avoid that the coating | coated part 31 will interfere with another member.

(Embodiment 2)
10 to 13 relate to the second embodiment of the present invention, and in this second embodiment, the shape of the covering portion 37 provided at the terminal portion of the parting portion weather strip 3 is the covering portion 31 of the first embodiment. The other parts are the same as those of the first embodiment. Hereinafter, the same parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

  As shown in FIG. 10, the covering portion 37 of the second embodiment is thinner than the covering portion 31 of the first embodiment as a whole. The covering portion 37 has a plate-like main body portion 37a integrated with the cut end surface 3a (shown in FIG. 13) of the parting portion-side weather strip 3. When the parting portion-side weather strip 3 is viewed from the end portion side along the longitudinal direction of the weather strip 3, a portion overlapping the core member 35 in the covering portion 37 bulges, and the bulging portion causes the main body portion to bulge. A thick portion 37b is formed on 37a. Since the core member 35 is located at a substantially central portion in the thickness direction of the inner wall portion 33, the outer wall portion 32, and the connecting wall portion 34, the thick portion 37b is also the inner wall portion 33, the outer wall portion 32, and the connecting wall portion. 34 is located in the approximate center of the thickness direction.

  As shown in FIG. 12, the thickness T2 of the main body portion 37a of the covering portion 37 can be set to, for example, 0.3 mm or more and 2.0 mm or less. Moreover, the height H of the thick part 37b of the coating | coated part 37 can be set to 1.0 mm or more and 2.0 mm or less, for example. Furthermore, the width W of the thick part 37b of the covering part 37 can be set to, for example, 1.0 mm or more and 2.0 mm or less.

(Effect of Embodiment 2)
In the second embodiment, since the thick portion 37b of the covering portion 37 is located at a portion corresponding to the core material 35, the cutting position of the core material 35 is the plate-shaped portion 35a and is plate-shaped. When the end portion of the portion 35a protrudes from the cut end surface 3a of the parting portion-side weather strip 3, the end portion of the plate-like portion 35a can be reliably covered with the thick portion 37b. Similarly, when the end portion of the connecting portion 35b of the core member 35 protrudes from the cut end surface 3a of the parting portion weather strip 3, the end portion of the connecting portion 35b can be reliably covered with the thick portion 37b.

  In addition, since the portion of the covering portion 37 that does not overlap with the core member 35 can be thinned, it is avoided that the end portion of the parting portion weather strip 3 is increased in size by providing the covering portion 37. The

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the automobile weather strip according to the present invention can be used by being attached to, for example, a door provided on a side portion of the vehicle.
