Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a tie edge used to cover the end faces of interior and exterior materials and to fit around windows.

[Conventional technology]

A conventionally used snap edge has a shape as shown in FIG. 3. In other words, the toe edge 1 is attached to the attachment body A such as the trunk edge or pillar through the nail B.
The structure was such that the building material C was fixed and then the building material C was inserted. Moreover, the width l1 of the attachment part 2 of the retaining edge ₁ and the width _l2 of the decorative piece 7 were approximately equal in size, and the receiving piece 8 was formed to have a width of about 2 to 5 mm.

[Problem that the invention attempts to solve]

In such a toe, the length of the attachment part and the decorative piece are the same, so it is difficult to drive a nail into it, leaving dents in the decorative piece or causing it to become deformed. ○A large step appears at the boundary between the surface of the building material and the toe, resulting in a lack of aesthetic appeal. ○ Since the width of the receiving piece is narrow, it is not possible to correct the decorative piece so that it is parallel to the surface of building material C. ○D receiving piece and building material C
The elasticity of the decorative piece 7 does not act sufficiently between the surfaces, resulting in a gap between the two members. ○ Since building material C is simply inserted into the toe edge, elasticity does not work sufficiently between the receiving piece and the decorative surface of the building material, and moreover, rainwater that enters from the decorative surface of the building material spreads onto the surface of the attachment part of the toe edge. . There were other drawbacks.

[Means for solving problems]

In order to eliminate these drawbacks, the present invention makes it easier to drive nails by making the mounting part protrude more than 10 mm from the decorative piece, and allows the rainwater that has entered to flow down without spreading, and also prevents the decorative piece from spreading. It cooperates with the receiving piece to hold the building material, and furthermore, the boundary between the surface of the building material and the toe edge is formed into a smart external shape, and a bent part is formed on the end cover piece of the L-shaped decorative part to make it easier to hold the decorative piece. We propose a toe edge that is formed to strengthen the spring effect and reliably hold down building materials.

〔Example〕

Hereinafter, one embodiment of the snap edge according to the present invention will be described in detail with reference to the drawings. Note that parts corresponding to those in FIG. 3 are given the same symbols and numbers. That is, FIG. 1 is a perspective view showing the above-mentioned snap edge 1, in which a surface-treated steel plate, a PVC steel plate, a stainless steel plate, and an aluminum plate are formed as shown, and the mounting portion 2 and the L-shaped decorative portion 5 are integrated. The overall cross section is U-shaped. To explain further,
The mounting part 2 has a long shape and includes a rib 3 consisting of at least one convex rib or one or more concave ribs (not shown) in the middle of the flat plate, and a tongue piece 4 provided at the tip of the rib 3. It is mainly useful for fixing the retaining edge 1 to the mounting body A.
In addition, the rib 3 cooperates with the L-shaped decorative part 5 to strengthen and clamp the building material C, prevent the end of the building material C from rattling, and when rainwater leaks into the stopper 1, the rainwater is transferred to the mounting body A, It also has the function of preventing rain from spreading to the back side of building material C. Further, the tongue piece 4 is formed by bending the lower end edge of the attachment part 2 into a seam shape to prevent danger during construction of the stopper edge 1. Also L
The letter-shaped decorative portion 5 is integrally formed from an end cover piece 6, a decorative piece 7, and a receiving piece 8 having a cross-section. Inward one edge of the direction, e.g.
It is bent at about 90 degrees. Furthermore, the decorative piece 7 is approximately parallel to the attachment part 2 and has a dimension smaller than the width of the attachment part 2 by at least 10 mm, and the receiving piece 8 is an inclined piece 9 that is inclined inward at an obtuse angle at the tip of the decorative piece 7. In addition to making the boundary between the surface of the building material C and the tong 1 smart, it also prevents the tip from waving and makes contact with the building material C in a stable state. It is formed from a patch 10 that can be reliably implanted. moreover,
A bent portion 6a is formed in the middle of the end cover piece 6 of the L-shaped decorative portion 5 along the longitudinal direction. This bent portion 6a strengthens the spring effect of the decorative piece 7 and prevents the decorative piece 7 from deforming. In addition, when the bent part 6a is provided at a position corresponding to the height of the inclined piece 9 from the decorative piece 7, it can also serve the function of holding the end of the building material C together with the receiving piece 8, as shown in FIG. can. In addition, when the toe edge 1 is used as a storage around a window, especially when used in the side part of the window, it functions as a waterproof groove between the window frame and the edge 1, and at the corner part (not shown), it can be placed at right angles. It also functions as a guide and a locking portion when attaching the cover between the abutted retaining edges 1. 1
Reference numerals 1, 12, and 13 indicate notches, which are provided as necessary when connecting the retaining edge 1. Although not shown, the inner surface of the end cover piece 6 is made of soft foam, rubber, EPDM, latex, etc.
Packing materials made from seeds are made of synthetic resin, rubber,
It is also possible to strengthen the packing property between the end face of the building material C and the snap edge 1 by disposing it with a hot melt adhesive.

Here, to explain the dimensional relationship, W ₁ is the dimension of the mounting part 2, W ₂ and W 3 are the dimensions from the end cover piece 6 to the rib 3, W ₄ is the dimension of the decorative piece 7, and W ₄ is the dimension of the cover piece 10. W ₅ , the dimension (thickness) of the end cover piece 6 is T ₁ , the thickness of the building material C is T ₂ , the notch 11
~13 dimensions (height) are H ₁ , H ₂ , H ₃ , width is W ₆ ,
If W ₇ and W ₈ , then W ₁ ≧W ₄ +W ₅ +7mm, W ₄ ≧
W ₂ , W ₃ > W ₄ , W ₆ ≦5mm, W ₇ ≦5mm, W ₈ ≦5
mm, T ₁ > T ₂ or T ₂ +2~5mm≒T ₁ , H ₁ = H ₂ =
_H3 is about 10-50mm.

〔Example〕

Now, using the toe edge 1 shown in Fig. 1, attach the building material C to the second
Assume that it is installed as shown in the figure. That is,
Fix the toe edge 1 to the mounting body A via the nail B, then attach the building material C, and when the predetermined length is reached, connect it using the notches 11 to 13 of the toe edge 1, and then Building materials will be installed in the same way.

[Effect of idea]

As described above, according to the toe according to the present invention, since there is a difference of 10 mm or more in the width between the mounting part and the L-shaped decorative part, it is easy to drive nails, and the decorative piece is not deformed. It has the characteristic that it does not cause scratches or dents. In addition, the ribs and receiving pieces provided on the attachment part allow the end of the building material to be held in a stable state without wobbling, and rainwater leaking inside can flow down without spreading. Furthermore, since the receiving piece is formed at an angle, the boundary between the surface of the building material and the toe edge becomes smart, making it possible to form a wall with a beautiful appearance. Besides, L
Since the end cover piece of the letter-shaped decorative part is provided with a bent part, the spring effect of the decorative piece is strengthened and the end of the building material can be reliably held. Moreover, when used as a storage area around a window, the bent part has a waterproof groove.
It has the feature of functioning as a guide and locking part for corner cover installation.
