The edge and the edge of the panel are concealed by an edge material made of a synthetic resin. As the edge material used for the peripheral surface treatment of the panel material, conventionally, FIG. 7, FIG. 8 or FIG.
Are used.

An edge member E ₁ shown in FIG. 7 has a protrusion 2 of an edge body 1 having a substantially T-shaped cross section fitted into a groove 4 which is shallowly recessed on the surface side of a panel material body 3. In the edge structure using such an edge material E ₁ , the synthetic resin film 6 is stuck on the cut surface 5 separately from the peripheral edge treatment of the panel material main body 3 to conceal. This requires a so-called glue sticking operation, which is very complicated.

On the other hand, the edge material E ₂ shown in FIG. 8 has a substantially L-shaped cross-section, and a locking side protruding from the back surface side of the front surface side 1 a of the panel surface side of the edge material main body 1. Part 7

Is inserted into a groove 4 formed in the front surface of the panel material main body 3 and is fixed by bonding. The peripheral edge of the panel material main body 3 is processed by inserting it into the concave groove 9 formed on the surface 5 and bonding and fixing it.

In the conventional edge material E ₂ , the locking side 7 is configured to be pushed into the groove 4 from the surface side of the panel material main body 3, and the conventional edge material E ₃ In the case of (1), since the locking sides 7 and 8 are press-fitted from two directions, these edge materials E ₂ and E ₃
Is extruded with a single wire and the panel material body 3 is extruded.
V-shaped notch (hereinafter referred to as
It is called a V-cut part. ) Cannot be formed,
Each edge material E ₂ , E ₃ must be composed of two long side bodies and two short side bodies whose both ends are cut at an angle of 45 degrees. And the short side body must be separately fitted to the corresponding peripheral portion of the panel material main body 3, and this operation is very complicated. There is a problem that it is difficult to mold with the same thickness and shape, and variation easily occurs.

As a structure of an edge material which can solve such a problem and form a V-cut portion, for example,
Edge material E ₄ having the structure as shown in FIG. 10 is considered.

The edge material E ₄ includes a front edge portion 10 that is in close contact with the entire peripheral surface of the front edge 5 of the panel material body 3, and an anchor protrusion side portion 11 protruding from the back side of the front edge portion 10. ,
A locking side 13 extending from a lower edge 12 of the front edge 10 to the back side of the panel material body 3;
And a front side 15 extending in a trapezoidal shape from the upper side 14 to the front side of the panel material main body 3, and the terminal side 15 a of the front side 15 is horizontally folded back to form a panel. It is configured so as to be in elastic contact with the surface of the material body 3.

[0009]

BACKGROUND problems] However, in the edge material E ₄ configured as described above, as shown in FIG. 11, the angle between the horizontal portion 15b and the butt sides 10 of the surface side portion 15 90 In the case where the molding is performed at a temperature of not less than the degree, there is a problem that the terminal side portion 15a rises from the surface of the panel material main body 3 and the product quality is deteriorated. Further, as shown in FIG. When the angle between the horizontal surface 15b and the edge 10 is less than 90 degrees,
The edge 10 is inclined outward, and as a result, the terminal edge 15a cannot be in close contact with the surface of the panel material main body 3, so that the terminal edge 15a is in a floating state and the product quality is reduced. There is a problem that it is very difficult to obtain molding accuracy.

[0010] The present invention has been made in view of such a situation, and its object is to provide an edge material,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the accompanying drawings.

FIGS. 1 to 4 show a case where the present invention is applied to a door P of furniture.
It is composed of a panel material main body 20 and an edge material 30 fitted on a peripheral portion of the panel material main body 20.

The panel material body 20 is formed of a decorative plywood or a decorative medium-density fiberboard (MDF). In this embodiment, the front shape is rectangular.

On the other hand, the edge material 30 is formed of a wire having a length covering the entire periphery of the panel material main body 20 by extrusion molding of PVC plastic.
For example, a plastic film F on which the same pattern as the surface pattern of the panel material body 20 is printed is stuck. Of course, a V-shaped cut portion 38 (see FIG. 1) is formed along the longitudinal direction of the edge material 30 at a portion bent at each corner of the panel material main body 20 except for the plastic film F. ing.

As shown in FIG. 5, the edge member 30 has a front edge portion 31 that is in close contact with the entire peripheral surface of the front edge 25 of the panel material body 20 and a protruding rear surface of the front edge portion 31. An anchor projection side 32 provided, a locking side 34 extending from the lower edge 33 of the edge 31 to the back side of the panel material body 20, and an upper edge of the edge 31 3
5 and a front side 36 extending to the front side of the panel material main body 20, and a lock rib side 37 protruding from the back side of the front side 36.

The edge 31 has a width substantially equal to the width of the edge 25 of the panel material body 20. An anchor projection protruding from the back side of the edge 31 is provided. The side portion 32 is press-fitted into the concave groove 21 having a U-shaped cross section formed in the opening 25 of the panel material main body 20 so that the edge material 30 does not fall off the panel material main body 20 carelessly. ing.

In this embodiment, the anchor projection side portion 32 is divided into a substantially U-shape so as to be freely expandable and contractible, and the outer side of each of the projections 32a is provided with the concave groove. 21 are formed with wedge-shaped irregularities 32b, 32b to be locked on the wall surface.

The front side 36 is separated from the upper side 35 of the edge 31 by the front side 20 of the panel material body 20.
inclined side portion 36a extending in a direction slightly separated from a
A horizontal side portion 36b extending in a horizontal direction from the inclined side portion 36a; and a panel material body 2 from the horizontal side portion 36b.
Elastic contact side portion 36c extended so as to elastically contact with the surface of No. 0
And is formed from.

On the back side of the horizontal side portion 36b, a supporting side portion 36e for preventing the dent of the edge member 30 is extended, and the lock rib side portion 37 is connected to the elastic contact side portion 36c. Of the panel material body 20 is inclined and extends from the back side of the panel material body 20 toward the front surface thereof.
Are fitted and locked in a locking groove 22 which is shallowly concavely formed on the front side 20a of the panel material main body 20.

Therefore, when the edge member 30 according to this embodiment is fitted to the peripheral portion of the panel member main body 20, the edge member 30 is located on the back side of the cut edge 31 and is located on the back side.
The adhesive 41 is applied to the surface excluding the adhesive 2 and the adhesive 42 is also provided between the elastic contact side 36c and the lock rib side 37.
Fill. By applying the adhesives 41 and 42, the adhesive strength between the edge material 30 and the panel material main body 20 is increased, and the adhesives 41 and 42 can prevent water seepage.

Next, one side of the panel material body 20 is press-fitted toward the corresponding edge 31 of the edge material 30, and the locking side 34 is locked to the back side peripheral edge 23 of the panel material body 20. At the same time, the anchor projection side 32 is inserted into the concave groove 21 formed in the cut edge 25 of the panel material main body 20. As a result, the lip 31 of the edge member 30 comes into close contact with the lip 25 of the panel material main body 20, so that water that has been dripped on the front and back surfaces of the panel material main body 20 and flows down enters the lip 25 of the panel material main body 20. As a result, it is possible to prevent the wood edge 25 from swelling.

Next, when the panel material main body 20 is pressed toward the corresponding edge 31 in the above-described procedure,
After the distal end portion 36d of the elastic contact side portion 36c of the front surface side portion 36 slides on the front surface side 20a of the panel material main body 20, the distal end portion 37a of the lock rib side portion 37 engages with the locking groove 22 of the panel material main body 20. It is fitted and locked. As a result, the edge member 30 is sandwiched between the locking side portion 34 and the lock rib side portion 37, so that the distal end portion 36d of the elastic contact side portion 36c is securely attached to the front side 20a of the panel material body 20. The edge member 30 can be firmly adhered, and the edge member 30 can be reliably prevented from rising.

Since the lock rib side portion 37 is formed with elasticity, the edge portion 30 has a cut edge 31
Strictly 90 degrees with the horizontal side 36b of the surface side 36.
Even if it is not formed frequently, the error can be absorbed by the elasticity of the lock rib side portion 37, and the front end portion 36d of the elastic contact side portion 36c can be securely brought into close contact with the front surface side 20a of the panel material body 20.

After one side of the panel material main body 20 is pressed into the corresponding cut edge 31 of the edge material 30 in this manner, the panel material main body 20 is turned down by 90 degrees and is connected to the one side. The other side is press-fitted in the same procedure toward the edge 31 of the corresponding edge material 30, and this is sequentially inserted.
By continuously press-fitting the other sides, the edge material 30 can be manually pressed into the entire periphery of the panel material main body 20.

When the edge member 30 is manually attached to the entire periphery of the panel member body 20 as described above, it is necessary to form the V-cut portion 38 on the edge member 30 in advance. As shown in FIG. 6, when fitted to the opposed long sides of the panel material main body 20, the rollers 40, 40, which are disposed along the transfer path of the panel material main body 20, have a substantially C-shaped plane.
Thereby, the edge member 30 can be automatically fitted to the facing long side of the panel member body 20.

In the above embodiment, the case where the present invention is applied to the door P of furniture has been described as an example. However, the present invention is not limited to this, and the present invention is not limited to this. It is needless to say that the present invention can be applied to other panel materials such as various decorative boards, partitions, wall materials, and architectural doors.

[0028]
