Abstract

PURPOSE:To enable a surface fastener to have a barrier function in such a way as keeping both surfaces thereof free from engagement in a contact condition under a low pressing force, and causing the engagement at a pressing force above the predetermined force. CONSTITUTION:Small engagement piece group 12 arrayed at the root face 11 of a surface fastener 10 is fitted with a cover sheet 15 to break upon exposure to a pressing force equal to or above the predetermined value from the small engagement piece group 32 of a mating member.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a hook-and-loop fastener in which a group of engaging small pieces are arranged in a planar manner on a base surface so that the hook-and-loop fasteners engage with each other while facing a counterpart having a similar structure, and this hook-and-loop fastener The present invention relates to a method for attaching a vehicle interior panel to a body using a vehicle interior panel.

2. Description of the Related Art For example, when attaching an interior ceiling panel to a body panel 9 on the roof of an automobile, as shown in FIG. At the same time, the hook-and-loop fasteners (well known as the trademark "Magic Tape") 2 are glued to the body panel 9, and the hook-and-loop fasteners 7 are glued to the corresponding positions on the body panel 9. First, the front end of the ceiling panel 1 is attached to the inner mirror, sun visor, etc. Using screw tapping 4, align the mounting holes 4a of the body panel 9 with the mounting holes 4b of the ceiling plate 1 and tighten them together. Next, the ceiling plate 1 is set in the mounting hole 3a of the body panel 9 using the clip 3 formed at the rear end. continue,
Push the center part of the ceiling board 1 onto the body panel 9 and fix it with these hook-and-loop fasteners 2 and 7.

0003

[Problem to be Solved by the Invention] However, it is difficult to adjust the position of the ceiling plate 1 to the normal assembly position and to fix the mounting holes 4a.
When the ceiling plate 1 is shifted in an attempt to align the mounting holes 4b and fix it, if a pressing force is applied and the hook-and-loop fasteners 2
must be disengaged and readjusted. In such a case, if the hook-and-loop fastener 2 is attached to the ceiling panel 1 made of a material with poor adhesion, such as felt, using double-sided adhesive tape, the hook-and-loop fastener 2 may engage with the other hook-and-loop fastener 7. If it comes off, work efficiency will be further reduced, and it may even lead to damage to parts. For this reason, as shown in FIG. 4, a method has been adopted in which an aluminum sheet 8 is adhered to a ceiling plate 1, and a hook-and-loop fastener 2 is adhered to the surface thereof with double-sided adhesive tape 5 to prevent the aluminum sheet from coming off. However, this method requires a separate aluminum sheet and requires additional man-hours for its attachment and gluing.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a hook-and-loop fastener having a barrier function that causes the engagement pieces to engage with each other when a predetermined pressure is exceeded. Furthermore, another object is to provide a method for attaching vehicle interior panels that can improve work efficiency using such hook-and-loop fasteners.

[0005]

[Means for Solving the Problems] The present invention has a group of engaging small pieces arranged in a planar manner on a base surface, so that both base surfaces face a group of engaging small pieces arranged on the other base surface. In order to achieve the above-mentioned purpose in hook-and-loop fasteners that have come to engage with each other in a state of It is characterized by having a sheet attached. Such hook and loop fasteners are used to attach hook and loop fasteners to at least the central part of the vehicle interior panel that is difficult to see, and to attach hook and loop fasteners to corresponding distributed positions on the body, and to connect the ends of the vehicle interior panel to the body through mounting holes. After aligning and fixing with fasteners,
If this method is adopted for attaching a vehicle interior panel in which the interior panel is pushed toward the body and both hook-and-loop fasteners are engaged, engagement of the hook-and-loop fasteners during the positioning stage can be prevented.

[0006]

[Function] When a hook-and-loop fastener engages with a mating hook-and-loop fastener, the cover sheet is interposed in the opposing state, thereby avoiding engagement with a slight pressure force, while on the other hand, if the hook-and-loop fastener exceeds a predetermined pressure force The cover sheet is damaged and engaged by the mating piece.

[0007]

[Embodiment] Fig. 1 shows the manufacturing process of a hook-and-loop fastener according to the present invention, in which a group of engaging pieces 12 are arranged in a planar manner on a base surface 11 between compression rollers 20 and 21 that are vertically opposed to each other. A normal hook-and-loop fastener 10 and a cover sheet 15 that covers the engagement piece 12 are supplied. This cover sheet is coated with adhesive using a coating gun 22. The cover sheet 15 is made of a crystalline thermoplastic resin, such as a PP homopolymer, whose molecules are oriented by compression stretch molding or the like and has a thickness of 10 to 40 μm. Its characteristics include high strength in the direction of molecular orientation and brittleness in the direction perpendicular to this direction, and it has already been widely used as, for example, packing string. The cover sheet 15 sprayed with adhesive is pressed onto the tips of the group-shaped engaging pieces 12 by compression rollers 20 and 21, and is also pressed into the hot air stove 2.
At 3 the adhesive is cured. As a result, Figure 2
As shown in FIG.
The cover sheet 15 is attached and covered, and the engaging small piece group 3 of the mating hook-and-loop fastener 30 is covered by the above-mentioned thickness setting.
2, if it is pressed with more than a predetermined pressing force intended for temporary fixing, it will be torn into lines.

When the hook-and-loop fastener 10 is used to attach the ceiling plate 1 shown in FIG. 3 to the ceiling body, as shown in FIG. Hook-and-loop fasteners 10 with sheets 15 are dispersed and bonded with a double-sided adhesive tape 5, and a normal hook-and-loop fastener 30 without a cover sheet 15 is bonded with a double-sided adhesive tape 33 at a corresponding position on a body panel 9. When positioning the ceiling plate 1 to be attached to the body panel 9, the engaging pieces 12, 32
They contact each other with the cover sheet 15 interposed between them, and cannot be engaged with each other even if a slight pressing force is applied from below, and while the positions are easily shifted in the facing state, the mounting holes 4a and 4b can be aligned and clipped. Positioning to the mounting hole 3a of No. 3 can be performed. When the ceiling plate 1 is pressed with a predetermined pressing force or more after positioning, the cover sheet 15 is pressed into place by the engagement small piece 32.
is torn and enters the gap between the engagement pieces 12, and proper engagement is performed.

[0009] For the cover sheet material, it is also possible to use polyethylene or the like as a synthetic resin capable of imparting the above-mentioned molecular orientation, or a thin aluminum sheet that does not have molecular orientation and has low elongation elasticity. . Furthermore, the present invention is applicable not only to ceiling panels but also to interior panels such as door trims. Further, the present invention is applicable even when the body does not have a surface shape corresponding to the ceiling board, but has a rib-like body arranged intermittently.

0010

As described above, according to the present invention, the cover sheet acts as a barrier against small pressing forces, and unnecessary engagement is prevented when adjusting the facing position with the mating hook-and-loop fastener. Therefore, it is possible to properly engage the parts after mutually positioning them in a facing state, and the efficiency of parts assembly using hook and loop fasteners is improved. Moreover, when engaging and disengaging to release erroneous engagement before positioning, problems such as damage to assembled parts or detachment of hook-and-loop fasteners are eliminated.

[0011] When such a hook-and-loop fastener with a cover sheet is used when fixing a large area of a vehicle interior panel that is hard to see to a predetermined position on the body, there is no engagement during the positioning stage, which improves work efficiency. It is extremely effective in improving
