Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a corner pat used to hide the outside and inside corners of the decorative edge that is attached to the meeting point between the interior wall and ceiling. It is something.

(Conventional technology and its problems) It is a practical technique that can be used in the outgoing and incoming corners of the decorative edge that is attached to the meeting point of the indoor wall and ceiling to hide the corner and make the finish look good. −
As is known in Publication No. 29470, etc., a corner pat for an inside corner is required for an inside corner, and a corner pat for an outside corner is required for an outside corner, and two types of corner pats must always be manufactured and prepared. However, there were considerable disadvantages and inconveniences in terms of economics and handling, such as a rise in manufacturing costs, an increase in the number of parts, and an increase in storage volume.

(Purpose of the invention) The object of the invention is to provide a corner part for an outside corner or an inside corner where one part can be used for both inside and outside corners.

(Means for Solving the Problems) In order to achieve the above object, the present invention uses a patch member whose longitudinal cross section is shaped to closely cover the decorative edge surface of the ceiling and has a predetermined length. A joint part is formed by forming a V-shaped cut part with a right angle apex in the longitudinal center of the planar shape, and part parts are formed on the left and right sides of the cut part, and the parts of each part are The free end side edge is a 45-degree inclined edge parallel to the cut edge of the V-shaped cut portion, so that parallelograms are connected via a joint in a plan view. .

(Example) Fig. 1 is a front view of the extended state of the corner part for external and internal corners according to the present invention, Fig. 2 is a plan view, Fig. 3 is an explanatory diagram of the state of use, and Fig. 4 is the corner part of the present invention. Fig. 5 is a plan view when the inventive part is used as an inside corner, Fig. 6 is a plan view when the inventive part is used as an inside corner,
The figure is an end view taken along line A--I of FIG.
The surface of the decorative edge 3 attached to the meeting point of the ceiling 1 and the interior wall 2 is covered with the outer corner and the inner corner,
The structure is such that the abutting portion of the decorative edge 3 is hidden.

More specifically, the part member 4 has a cross-sectional shape that covers the surface of the decorative edge 3 and has a predetermined length, and has a V-shaped cut portion 11 with a right-angled apex at the center in the longitudinal direction of the planar shape. By forming the joint parts 7 and 8, the pad parts 5 and 6 are formed on the left and right sides of the cut part 11, respectively, and the free end side edge 1 of each of the joint parts 5 and 6 is formed.
0 and 10 are 45-degree inclined edges parallel to the respective cut edges 9 and 9 of the V-shaped cut portion 11, and the parallelogram in the planar shape is the joint portions 7 and 8.
It has a structure in which they are connected via a , and is integrally molded from synthetic resin.

When using a cutlet with the above structure in an inside corner, as shown in FIG. In this state, it is used by adhering it to the surface of the decorative surrounding edges 3, 3 arranged at right angles to the corner.
As shown in the figure, the patch parts 5 and 6 are connected to the joint parts 7 and 8.
Cut it off to make two parts, and the free end side edges 10, 1
It is used by abutting the two sides to form a right angle and adhering them to the surfaces of the decorative edges 3, 3 that form the protruding corners.

(Effects of the invention) The corner parts for the outside and inside corners of the invention have a cross-sectional shape that covers the decorative edge surface of the ceiling,
A patch member having a predetermined length, in which a joint part is formed by forming a V-shaped cut part with a right angle apex in the longitudinal center of the planar shape, and patch parts are formed on the left and right sides of the cut part. At the same time, the free end side edge of each putt part is an inclined edge of 45 degrees parallel to the cut edge of the V-shaped cut part, so that parallelograms in the planar shape are connected via the joint part. Because of this shape, when using it for an inside corner, bend the left and right parts around the joint and butt the cut edges together to make a right angle, and when using it for an outside corner, fold the left and right parts. The parts can be separated at the joint to form two parts, and the 45-degree inclined free end edges can be butted against each other to form a right angle.

For this reason, according to the present invention, two types of corner parts are always prepared for production, just like in the past, an inside corner part requires an inside corner part and an outside corner part requires an outside corner part. This eliminates all disadvantages and inconveniences in terms of economics and handling, such as high production costs, increased number of parts and storage volume, and one part can be used for both inside and outside corners. Corner parts can be provided at low cost.
