ことが出来る。This type of surface fastener made of a so-called rail-type molded surface fastener member is easy to adjust its movement in the vertical direction and has a large engaging strength in the lateral direction and the latching direction (the direction perpendicular to the surface of the substrate portion). Therefore, not to mention the field of application of conventional surface fasteners, especially in the field of non-clothing fields where it is necessary to adjust the mounting state and the above characteristics can be utilized, such as joints for tent sheets, interior and exterior in the housing field. It can be widely used in various fields such as material joints and joint materials for various seat covers.

くられ、密着性が高く係止が強固であるが、屈曲性が小
さく自由度が少ない。By the way, in this type of known molded surface fastener member, the entire surface fastener member including the engaging piece is usually hard in order to enhance the engaging property of the rail-shaped engaging piece. It is made of a material having a high elastic modulus, for example, a hard vinyl chloride resin, and it is hard just like a long ruler, and when the two surface fastener members are fitted and engaged with each other, a snapping sound is generated. It is made tight enough to tear and has high adhesion and strong locking, but it has little flexibility and little freedom.

難である。However, such a molded surface fastener member can be adjusted in flexibility or position in a mounting structure in which flexibility of an object to which it is attached is maintained, or in accordance with a procedure of mounting work or adjustment of a locking direction or a positional deviation. Is mandatory. However, once this type of molded surface fastener member is locked and integrated, the molded surface fastener member itself is hard, and the two surface fastener members have a high degree of close contact, although the engaging force and the adhesiveness are high as described above. As a result, the flexibility of the surface fastener is naturally low, and even if an object is to be installed along a adherend with a curved surface, the curved surface is not easily curved and has a smooth surface. The mated state cannot be achieved, and if the bent state is to be strengthened again, the engagement is likely to be disengaged, and its adjustment is actually very difficult. Further, it is difficult to roll or fold the object with the surface fastener member attached to the object, even if the object is compactly stored for transportation.

理由の故にその面ファスナーとしては実用上不満足なも
のであり、いわんや、より柔軟で曲面のある対象物への
係止材としては適用できない。As described above, the rail-type molded surface fastener member has a high engaging property because it is hard, but conversely, therefore, the molded surface fastener member itself is hard, so that the surface fastener member is There is a big inconvenience that the application means and the range of the molded surface fastener are extremely limited due to the fact that the mounting means itself when mounting on a target object becomes difficult, and such a molded surface fastener. Is a practically unsatisfactory surface fastener for the above reason even if it is a relatively flexible object, such as a tent sheet, and so on. Not applicable as a locking material.

じてくるのである。Therefore, in order to eliminate the inconvenience, it is conceivable to mold the molded surface fastener member with a soft resin. However, if the surface fastener member is simply made of a soft resin, the surface of the substrate is Since the flexibility is large, if the object to which the surface fastener member is attached is flexible, the surface fastener member itself attached thereto is easily bent as described above, and the substrate surface is not firm, There is another big problem that the engaging piece is likely to fall over and escapes easily, and the engaging piece is easily disengaged, and the resin becomes softer, so that the performance at high temperature is significantly deteriorated.

While taking advantage of the features
The fastener itself is flexible and has good flexibility, the range of the object is not limited, and it is easy to adjust the deviation when the object is engaged with the fastener, and a fastener member that is also excellent in attachment to the object to be attached is provided.

である。DISCLOSURE OF THE INVENTION The inventors of the present invention have made diligent studies on resin molded surface fastener members that meet various requirements and purposes as described above, and finally compared the engaging piece and the entire surface fastener member of the substrate portion. In order to prevent the engagement element part from sticking due to such bending of the board part, the board part is soft and becomes softer when the temperature rises. In addition, if the reinforcement layer made of a hard and heat-resistant resin is formed in multiple layers at the base, that is, at the base part, the base of the engaging piece is solidified and collapsed while having flexibility and flexibility as a surface fastener member. The inventors have found that it can be made difficult to improve the engaging force, and that the performance can be maintained at high temperature, and the present invention has been completed.

もよい。In the present invention, the surface or / and the inner surface of the substrate portion 1 of the above-mentioned surface fastener member is formed with a multi-layered layer of the resin (II) as the reinforcing layer 3 of the substrate portion 1. It is important that the resin (II) layer is harder and more heat resistant than the resin (I) layer that basically constitutes the fastener member. Usually, the hardness difference between Resin II and Resin I is 5 ° or more. The reinforcement layer 3 made of this resin (II) is a resin layer that is harder and has heat resistance because it is used to reinforce the roots of the soft base plate and the engaging piece and to improve heat resistance and board strength. It is necessary. It is desirable that the elastic modulus does not decrease even at high temperatures. In the present invention, the high temperature softening degree (K), which is expressed as the ratio of the elastic modulus at room temperature to the elastic modulus at a temperature of 50 ° C. or higher, is used as an index showing such properties. That is, this high temperature softening degree (K)
In that, that of resin (II) (KII) must be lower than that of resin (I) (KI), ie K
It was found that I / KII needs to be 1.1 or more, and more preferably 1.2 or more. If KI / KII is less than 1.1, there is no reinforcing effect with the resin (II). Needless to say, the resin (II) preferably has good adhesion and compatibility with the resin (I). Such a resin (II) may be selected from resins different from the resin (I), and resins of the same type may be used as long as hardness and heat resistance can be improved by reducing the plasticizer. May be used.

As shown in FIGS. 2 (a) and 2 (b), the structure may be such that the back surface portion or the front surface portion of the substrate portion 1 is laminated or embedded.

It is preferable that the relationship between the double-width of the sleeve width (D) and the sleeve height (E) satisfies the following expression (1). A ≦ E ≦ A + 1.2D (1) The sleeve height (E) is from the height (A) from the straight line (L) parallel to the board 1 to the top of the engagement piece 2 If it is too small, it will be difficult to smoothly lock and integrate the two molded surface fastener members, and even if two molded surface fastener members are locked and integrated, lateral adjustment will be difficult. Also, from the straight line (L) where the sleeve height (E) is parallel to the board, to the engaging piece 2
If the value obtained by adding 1.2D to the height (A) up to the top of the sheet is exceeded, when the two molded surface fastener members are locked and integrated, the engaging pieces 2, 2, 2, ... It is difficult to say that the clearance is large and the locking is integrated. Further, the distance between the board portions and the deviation of the flatness are large, and the engaging pieces are prone to fall, so that the engaging pieces are easily disengaged.

好ましい。Further, the two molded surface fastener members can be easily locked and integrated, and when the two molded surface fastener members are locked, the bending property is good in the engaged state and the lateral movement is slightly moved. To do this, double the sleeve width, ie (D)
It is preferable that the interval (B + S) between the engaging pieces satisfies the following (3) and (4). 0.1 (B + S) ≦ D ≦ 0.45 (B + S) ···· (3) 1.2W ≦ S ····・ ・ ・ ・ ・ (4) 2 if the width under the sleeve (D) is less than 10% of the space between the engaging pieces 2
It becomes difficult to lock the molded surface fastener members.

It is preferably 0.5 to 2.5 mm. If the thickness of the leg is less than 0.3 mm, it is easy to deform and it is difficult to stably form the engaging piece 2 having a good cross-section expansion head, the strength of the engaging piece is weakened, and the engagement is easily performed by an external force. It may come off. On the other hand, if the thickness exceeds 3 mm, the wall thickness is poor, the balance with the sleeve is poor, the engaging property and the moldability are deteriorated, the space is further increased, and the locking efficiency is reduced.

If it is less than 0 mm, it becomes difficult to stably mold the engaging piece 2 having a good bulging cross section. Further, even if it could be molded, the engagement piece 2 is small, and the clearance is insufficient.
It becomes difficult to smoothly lock and adjust the engagement pieces 2 of the molded surface fastener members. If the height (H) exceeds 5 mm, the positional deviation from the object to be mounted is large and the locking space is increased, and the parallelism between the engaging piece 2 and the board portion 1 that are locked to each other is extremely poor. As a result, the balance of engagement is lost, and the locking is easily released by an external force or the like.

m, preferably 0.5 to 3 mm is suitable. Board part 1
If the thickness is less than 0.3 mm, the molded surface fastener member may be bent, resulting in poor handleability. Further, since the board portion 1 is easily bent and the engaging piece is easily rubbed, the locking may be released when the two molded surface fastener members are locked and integrated. When the thickness of the substrate portion 1 exceeds 5 mm, the mounting space between the objects to be mounted increases, the amount of resin used increases, the cost increases, and the moldability deteriorates. The thickness (T) of the leg portion of the substrate portion 1 and the thickness (W) of the engaging piece 2 provided upright on one surface of the substrate portion 1 are the shape of the surface fastener member, the performance, the hardness of the resin used, and the bending. It is appropriately determined according to the elastic modulus, and the thickness method and shape can be appropriately changed as necessary.
