Description

[Detailed Description of the Invention] The present invention provides at least one of a pair of opposing surfaces in a groove for forming a corner of a template plate material.
The present invention relates to a template plate material in which an adhesive storage groove is formed to accommodate an adhesive when the opposing surfaces are joined to each other.

It has a groove that gradually expands from the sharpest deepest part toward the other side, leaving a bending layer on one side, and a corner part is provided by bonding a pair of opposing surfaces that form this groove to each other. Conventionally, in a template plate material for forming a template, the pair of opposing surfaces were both formed by a uniform flat surface, so when these opposing surfaces were bonded together, the adhesive would not adhere to the outside of the corner. It is extruded to the surface and solidifies as it is, which not only spoils the appearance of the corner but also causes various inconveniences when using the template.

For example, in FIG. 1, the adhesive 2 is extruded to the outer surface and solidified at the corner of the template A, which is formed by adhering the opposing surfaces in the grooves of the plate material 1 to each other. As shown in the figure, if the adhesive 2 has solidified on the outer surface of the corner of the template A in this way, even if you try to apply the template A to the corner of the member 3, for example, the adhesive 2 will not work properly. There is an inconvenience that the corner portion and the corner portion of the member 3 do not align accurately and come into close contact with each other, and a gap is created between the surface of the template A and the surface of the member 3.

Therefore, the main object of the present invention is to obtain a plate material for a template in which the adhesive is not pushed out to the outer surface even when opposing surfaces in the groove of the plate material are joined to each other.

An embodiment of the present invention will be described below with reference to the drawings. First of all, in FIG. 2, a plate material 4 consisting of a relatively thin flexible layer 5 such as a decorative sheet made of vinyl chloride on one side and a relatively thick substrate layer such as plywood has a flexible layer 5 on one side. Leaving the layer 5 intact, a groove is formed that gradually expands from the sharpest deepest part toward the other side. A pair of opposing surfaces 6, 6' forming this groove are provided with opposing surfaces 6, 6' from the enlarged end of the groove.
Notch-like adhesive storage grooves 7, 7' are formed by cutting out 6', and can accommodate adhesive when the respective opposing surfaces 6, 6' are joined to each other.

Therefore, when forming template B as shown in FIG. 3 by bonding the pair of opposing surfaces 6, 6' to each other, the adhesive 8 between the pair of opposing surfaces 6, 6' is notched. By flowing into the notch-shaped adhesive storage grooves 7, 7', it is not pushed out to the outer surface of the corner of the template B, and moreover, the notch-shaped adhesive storage grooves 7, 7'
Due to the presence of 7', the adhesive area becomes relatively large,
The joint strength of the corners of template B increases. Since the notched adhesive accommodating grooves 7, 7' are formed by cutting out the opposing surfaces 6, 6', the notched adhesive accommodating grooves 7, 7' are formed by cutting out the opposing surfaces 6, 6'.
7' is formed large so that a large amount of adhesive can be accommodated, thereby further improving the bonding strength.

Furthermore, since the adhesive is not extruded to the outer surface of the corner of template B, when template B is applied to the corner of member 9 as shown in FIG. It can be aligned and closely attached to the corner of No. 9.

As described above, according to the present invention, since the adhesive storage groove is formed in the pair of opposing surfaces for forming the template, the pair of opposing surfaces are bonded to each other to form the template. Even when the adhesive is not pushed out to the outer surface of the template corners, not only does the appearance of the template remain intact, but the adhesive strength is increased by expanding the bonding area of the corners. Moreover, even when the template is applied to a corner of another member, the template can be perfectly aligned and tightly attached to the corner of the other member.

Further, since the adhesive storage groove is formed by cutting out the opposing surface, a large amount of adhesive can be stored, and as a result, the bonding area of the corner portion is further expanded, which has the advantage of increasing adhesive strength.
