Abstract

PROBLEM TO BE SOLVED: To provide a shock absorbing edge material whose appearance is excellent even if a curvature radius of corners of furniture is small, and which prevents a hand, an arm, a head, etc. from being injured even when they hit it.SOLUTION: An edge material 9 used for end parts of furniture is composed of a hard part 5 and a soft part 1. The soft part 1 is generally T-shaped, and a slightly recessed part 2 is formed in the upper part. A section surrounded by the hard part 5 and the soft part 1 is hollow. The edge material 9 is made to circulate on the edge of the furniture, and when performing butting, a filling material is put into a hollow part 3.

Description

  The present invention relates to an edge material used for an end portion of furniture such as a table, a desk, and a counter.

Conventionally, as shown in FIG. 4, an edge material for impact reduction is known.

  However, if the radius of curvature of the corners of furniture is small, the head of the arrowhead protrudes as shown in FIG. There was a drawback of not.

  The present invention has been studied in view of such a situation, and is an edge material 9 used for an end portion of furniture, and the edge material 9 includes a hard portion 5 and a soft portion 1, and the soft portion 1 is substantially the same. An edge material characterized in that it is T-shaped and the upper part is formed with a dent 2 somewhat.

  According to the present invention, the head of the arrowhead does not protrude, and the upper part of the T-shaped soft part is somewhat recessed, so that the impact is easily transmitted to the left and right hollow shapes even if an impact force is applied. Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view of an edge material 9 according to the present invention, which is generally in the shape of a scissors and is composed of a hard portion 5 and a soft portion 1, and a portion surrounded by the hard portion 5 and the soft portion 1 is hollow. Has a buffering effect. The edge material 9 is obtained by coextruding TPO (thermopolyolefin). TPO is an elastomer (elastic body) at room temperature and has rubber-like properties.

  The hardness of the substantially T-shaped soft part 1 is 40 to 60 in Shore A hardness based on JIS K 6253, and a dent 2 is formed somewhat toward the upper center, even if it hits the hand, arm, head, etc. Impact is mitigated by the hollow shape.

  The hard part 5 from which the arrowhead 6 protrudes in the center part has a hardness of 70 to 90 in Shore A hardness based on JIS K 6253, and the soft part 1 and the hard part 5 have a hardness within the above range. Due to the recess 2, even when the curvature radii at the four corners of the furniture are small, the hard portion 5 of the edge material is unlikely to protrude at the bent portion.

  More specifically, it is preferable that the recess 2 is recessed by about 5% to 15% with respect to the maximum height of the protrusion 4 at both ends of the soft portion 1, and can be flat at the bent portion below the lower limit. The difference in the appearance between the straight portion and the bent portion is likely to occur, and if the upper limit is exceeded, the convex portions 4 at both ends of the soft portion 1 tend to be difficult to be stretched and attached.

  Further, as shown in FIG. 1, the hard portion 5 is somewhat raised at the central portion, has a bow shape, and has a raised portion 7. By making it bow-shaped, the close contact with the end of the furniture becomes strong and moisture does not enter.

  It is preferable to inject a filling material such as foamed resin, paper, cloth, or an adhesive into the hollow portion 3 when the edge member 9 is circulated around the end portion of the furniture to make a butt. By doing so, a step is hardly formed at the seam, and the seam is not peeled off.

  In particular, fiber materials such as paper and cloth are preferable because they easily absorb the adhesive, increase the bonding area, and have an appropriate hardness. In the present invention, a fixed shape material made of paper is packed, and the adhesive Is applied. In the resin member, an increase in the bonding area cannot be expected in the filling portion, and the adhesion of the joint portion is likely to be weak. The fibrous material to be filled preferably has an edge material hardness of 40 to 60 in terms of ASKER C hardness based on JIS K 7312 when filled. If it is less than the lower limit, it will be too soft and dent, and if it exceeds the upper limit, it will become too hard and it will be easy to get injured when it hits your hand, arm or head.

  When the edge material of the present invention is applied to furniture, a wood fiber board having a specific gravity of 0.6 to 1.0 can be used as a base material for furniture. For example, a medium fiber board (MDF) ), A hard fiber board (HDF) and the like can be suitably used. Here, the wood fiber board is preferable because it has no directionality, and unlike a single board for plywood, there is no back crack and excellent smoothness. A decorative material is bonded to the front and back of the base material.
