[Industrial applications]

 TECHNICAL FIELD The present invention relates to a stairs replacement metal fitting used when a new tread decorative plate and a decorative decorative plate are pasted on an existing tread and a decorative plate.

[0002]

[Prior Art]

 Conventionally, when the treads and indentation boards of stairs became old, these old treads and indentation boards were peeled off and new treads and indentation boards were pasted.

However, with this method, it takes a lot of time to peel off the existing tread plate or indentation plate, the working period becomes long, and the construction cost becomes high.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to provide a stairs-replacement metal fitting that allows a new decorative plate to be pasted from the upper surface of an existing tread plate or indentation plate without peeling it off when the tread plate or indentation plate of the stairs is reattached. Especially.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the metal fitting for stairs replacement of the present invention is provided with a tip end surface covering fixing piece vertically on the lower surface of the horizontal strip-like fixing piece, and one end in the width direction of the fixing piece A standing wall is provided along the edge, the upper end of the standing wall is bent toward the other end in the width direction to form a tread suppressing piece, and a tread decorative plate is fitted between the tread suppressing piece and the tread fixing piece. It is characterized in that a groove is formed.

[0006]

[Action]

 After pasting a new embossing decorative plate on the upper surface of the existing footboard, fix the tip cover fixing piece to the outer surface of the tip end surface of the existing footboard, and fix the footplate fixing piece to the top end of the footboard. Attach the stairs replacement metal fittings to the existing stairs, insert the tip of the new tread decorative plate into the tread decorative plate fitting groove, and stretch the new tread decorative plate on the upper surface of the existing tread.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a stair-replacing metal fitting, which is a horizontal strip and has an existing tread plate 13 (Fig. (See 3) The length of the tip surface covering fixing piece 4 is set vertically along the longitudinal direction, and the lower end of the tip surface covering piece 4 is bent toward the one end in the width direction to form the lower receiving piece 5. Be done.

Further, a standing wall 6 is provided above one end edge in the width direction of the tread plate fixing piece 2 along the longitudinal direction, and an upper end of the standing wall 6 is bent to the other end side in the width direction so that the tread suppressing piece is formed. 7 is provided, and a tread surface decorative plate fitting groove 8 is formed between the tread plate fixing piece 2 and the tread suppressing piece 7.

As shown in FIG. 2, one end of the tread suppressing piece 7 extends so as to incline downward to a length where the tip of the tread suppressing piece 7 coincides with the upper end of the lower receiving piece 5 to form an upper suppressing piece 9. Now, a wood fitting groove 10 is formed between the lower receiving piece 5 and the upper holding piece 9 along the width of the stairs.

Next, a method of using the stair-replacing metal fitting 1 will be described.

First, after a new embossing decorative plate 12 is attached to the surface of the existing embossing plate 11 by bonding or by fixing metal fittings, the tip surface covering fixing piece 4 is brought into contact with the tip surface of the existing tread plate 13. Fix with appropriate fasteners 14 such as nails, screws, etc., and abut the footplate fixing piece 2 on the tip of the upper surface of the footboard 13 and also fix it with the fasteners 14 '. As shown in FIG. Attach the metal fitting 1 for replacement.

Next, the tip end of a new tread decorative plate 15 is fitted into the tread decorative plate fitting groove 8 of the stair replacement metal fitting 1, the tread decorative plate 15 is attached to the upper surface of the tread 13, and the wood fitting groove 10 is attached. The oblong splint 16 is fitted in and fixed by adhesion or the like.

In the same manner, a new tread decorative plate 15 and a dented decorative plate 12 are laid in order from the bottom on the existing stairs in the same manner.

If a cushioning material is filled between the existing tread plate 13 and the new tread decorative plate 15, cracking of the tread decorative plate 15 due to load or impact from above can be prevented, and when climbing up and down stairs. Impact noise can be prevented. Further, a notch having the same thickness as the thickness of the tread plate fixing piece 2 of the staircase replacement metal fitting 1 is formed at the front end of the back surface of the tread decorative plate 15, and when the notch and the tread plate fixing piece 2 are fitted, the tread plate No gap is formed between the tread 13 and the tread decorative plate 15, and the tread decorative plate 15 is unlikely to crack.

FIG. 4 shows a second embodiment of the present invention, which is the same as the first embodiment shown in FIG. 1 except that the tip edge of the upper holding piece 9 projects from the tip edge of the lower receiving piece 5. It has almost the same structure.

Further, FIG. 5 shows a third embodiment of the present invention, in which the vertical walls 17, 17 'for preventing falling of the splints are provided at the tip edge of the lower receiving piece 5 and the tip edge of the upper holding piece 9. They are provided opposite each other. Since other configurations are almost the same as those of the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

It should be noted that if unevenness is provided on the upper surface of the tread suppressing piece and the upper suppressing piece, it will prevent slippage, and if coloring is applied, this surface will be exposed on the staircase surface and will serve as an edge decoration, so that it will be different from other interior colors Can be combined to create a beautiful interior.

[0019]

[Effect of the device]

 According to the stairs replacement metal fittings of the present invention, it is possible to attach a new tread decorative plate and a decorative decorative plate without peeling off the existing tread plate or indentation plate, so the stairs replacement work can be done without trouble. It can be installed easily in a short period of time, and since the tread suppressing piece and the upper suppressing piece appear like edging on the tip edge of the tread, it is excellent in design and the tip edge of the tread is protected. Hard to be damaged.

Further, since the existing tread plate remains under the new tread decorative plate, it exerts a reinforcing effect against the load from above, and thus the tread decorative plate can be thin.
