[Industrial applications]

 This invention relates to a tile mounting rail.

[0002]

[Prior art]

 Conventionally, as a method of mounting tiles, a long tile mounting rail is fixed on the mounting surface, and the tiles are mounted by engaging the engaging claws on the mounting rail with the grooves on the back surface of the tile. It has been known.

FIG. 6 shows an example thereof. In the figure, reference numeral 100 denotes a long metal tile mounting rail, which has engaging claws 102 and 104 which are continuous at the edges in the width direction (vertical direction), and each engaging claw 104 of the upper and lower mounting rails 100. , 102 is engaged with a groove 108 formed on the back surface of the tile 106 to hold the tile 106.

However, in the case of the mounting rail 100, since the engaging claws 102 and 104 are continuously formed in the longitudinal direction, it is difficult to bend the engaging claws 102 and 104 (the direction perpendicular to the plate surface), and thus the corners. There is a problem that it is difficult to mount the tile 106 using the mounting rail 100 when the tile mounting surface is curved in a portion or the like.

FIG. 7 shows an example of a mounting rail improved by the present inventors. In this tail mounting rail 110, elasticity is provided along the width direction (vertical direction) edge of the plate-shaped portion 112. Engaging claws 114 are provided, and notches 116 are formed between the elastic engaging claws 114 and 114.

In the case of this mounting rail 110, the mounting rail 110 can be easily bent in the direction perpendicular to the plate surface based on the notch 116 formed between the elastic engaging claws 114 and 114. It is possible to mount the tiles using the mounting rail 110 on the mounting surface of the tile.

[0007]

[Problems to be solved by the device]

 However, in the tile mounting rail 110, when the notch 116 is formed with a narrow width as shown in the drawing (for the purpose of bending the mounting rail 110, the width of the notch 116 is narrow enough), the relative The width of the elastic engaging claw 114 becomes wide, and the workability when the tile is engaged with the elastic engaging claw 114, that is, when the tile is fitted into the pair of elastic engaging claws 114 in the groove on the back surface is poor. It turns out that there is a problem.

When the spring force of the elastic engaging claw 114 is too strong, a large force is required when the elastic engaging claw 114 is elastically deformed against the spring force and then fitted into the groove of the tile. Therefore, when the tile is pushed in, the elastic engaging claw 114 is not elastically deformed sufficiently in a predetermined direction, and the elastic engaging claw 114 does not fit deeply into the groove on the back surface of the tile.

Further, in the case of this mounting rail 110, the flexibility (deformability) of the plate-shaped portion 112 itself becomes too high due to the formation of the notch 116, so that the mounting rail 110 can be used as a nail, a screw, or the like on the mounting surface. It was found that there is a problem that the mounting rail 110 is deformed into a wavy shape and does not adhere sufficiently to the mounting surface when it is fixed, which makes it difficult to finish the tile construction surface sufficiently flat.

[0010]

[Means for Solving the Problems]

 The invention of the present application has been made to solve such a problem. Thus, the tile mounting rail according to the invention of the present application has a plate-shaped portion extending in a longitudinal shape which is a fixed portion to the mounting surface and a width of the plate-shaped portion for engaging with and holding the groove on the back surface of the tile. A tile mounting rail having engaging claws formed at respective end edges in the direction, at least one of the engaging claws being an elastic engaging claw, A notch is provided between the engaging claws and the width of the elastic engaging claw is smaller than the width of the notch (claim 1).

A tile mounting rail according to another invention of the present application is characterized in that reinforcing ribs are continuously formed in the longitudinal direction along each edge of the plate-like portion (claim 2).

A tile mounting rail according to still another invention of the present application is characterized in that a protruding height of the engaging claw from the mounting surface is higher than a depth of a groove on the rear surface of the tile. Item 3).

[0013]

[Action and effect of the device]

 As described above, according to the first aspect of the present invention, the notch is provided between the engaging claws and the width of the elastic engaging claw is smaller than the width of the notch. The spring force of the elastic engaging claw is weakened according to the size of the. When such a mounting rail is used, when the tile is engaged with the elastic engaging claw in the groove on the back surface, the elastic engaging claw can be easily elastically deformed, so that the mounting workability is improved.

The mounting rail can be bent in a direction perpendicular to the plate surface based on the notch formation, and the mounting rail can be mounted even when the mounting surface such as a corner portion is curved. The tiles can be easily attached using.

According to the second aspect of the present invention, the reinforcing ribs are continuously formed along the edge of the plate-shaped portion of the mounting rail, whereby the rigidity of the plate-shaped portion is effectively increased, and thus the mounting rib is provided. When the attached rail is fixed on the mounting surface, the mounting rail is prevented from being deformed in a wavy manner as described above, and the mounting rail comes into close contact with the mounting surface. Therefore, when tiles are mounted on this mounting rail, the tiled surface can be finished sufficiently flat.

Embodiment An embodiment of the present invention will now be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 denotes a metal-made tile mounting rail having a longitudinal shape, which has a plate-shaped portion 12 having a predetermined width in the vertical direction, and a screw or the like in a mounting hole 14 formed in the plate-shaped portion 12. Is fixed to the mounting surface 16 (see FIG. 2).

Engaging claws 18 and 20 for holding tiles are provided on the upper and lower edges of the plate-like portion 12. One (upper edge) engaging claw 18 has a rising portion 21 that projects from the plate-shaped portion 12 in a direction perpendicular to it, and an action portion 22 that extends from the tip of the rising portion 21 in a direction parallel to the plate-shaped portion 12. 2 and the action portion 22 thereof comes into contact with the bottom surface of the dovetail groove 26 formed on the back surface of the tile 24 as shown in FIG.

On the other hand, the engaging claw 20 at the lower edge is an elastic engaging claw, and is composed of a rising portion 28 projecting from the plate-shaped portion 12 in a direction perpendicular to the plate-shaped portion 12 and a folded-back action portion 30.

The engaging claws 18 and 20 are provided at predetermined intervals along the longitudinal direction, and a notch 32 is provided between each of the engaging claws 18 and 18 and 20 and 20. In this example, the engaging claws 18 and 20 have the same arrangement pitch and width, and the width of the engaging claws 18 and 20 is smaller than the longitudinal width of the notch 32, that is, as shown in FIG. As shown, the width A of the engaging claws 18 and 20 is smaller than the width B of the notch 32.

Further, as shown in FIG. 2A, the protrusion height of these engaging claws 18 and 20 is made higher than the depth of the dovetail groove 26 in the tile 24.

As shown clearly in FIG. 1A, circular reinforcing ribs 36 are provided on the upper and lower edges of the plate-like portion 12.

FIG. 3 shows a procedure for mounting the tile 24 using the tile mounting rail 10 of this example. As shown in the figure, in order to mount the tile 24 on the mounting surface 16 using the tile mounting rail 10 of this example, first, the tile mounting rail 10 is fixed to the mounting surface 16 and the upper edge is engaged. The upper edge of the dovetail groove 26 on the rear surface of the tile 24 is engaged with the claw 18. Specifically, the action portion 22 of the engaging claw 18 is brought into contact with the bottom surface of the dovetail groove 26 to engage with the upper end edge of the dovetail groove 26.

Subsequently, when the lower end side of the tile 24 is pushed in as shown in (B), the engaging claws (elastic engaging claws) 20 at the lower end edge receive a pushing force in the action portion 30 and are elastically deformed. Then, after entering the inside of the dovetail groove 26, the shape is restored and the front end of the folded-back acting portion 30 engages with the side surface of the dovetail groove 26, and the tile 24 is held.

In the tile mounting rail 10 of this example, since the protrusion height of the engaging claws 18 and 20 is set higher than that of the dovetail groove 26 of the tile 24, the tile 24 is fitted as shown in FIG. At this time, the tips of the engaging claws 18 and 20 can be fitted into the dovetail groove 26 sufficiently deeply, and the engaging claws 18 and 20 can be engaged with each other while being surely brought into contact with the bottom surface of the dovetail groove 26. You can

Since the width A of each engaging claw 18, 20 is smaller than the width B of the notch 32, the spring force of each engaging claw 18, 20, especially the elastic engaging claw 20, is appropriate. Therefore, when the tile 24 is fitted into the engaging claws 18 and 20 in the dovetail groove 26, the elastic engaging claws 20 can be easily elastically deformed to facilitate the tile fitting work. be able to.

Further, since the reinforcing ribs 36 are continuously formed on the upper and lower edges of the plate-shaped portion 12 of the tile mounting rail 10, the entire tile mounting rail 10 has a predetermined rigidity, and the mounting surface 16 When the tile mounting rail 10 is mounted on, the corrugated deformation does not occur, and it can be sufficiently brought into close contact with the mounting surface 16. Therefore, when the tile 24 is mounted via the tile mounting rail 10, the tile processing surface can be finished flat.

The tile mounting rail 10 of this example can be easily bent in the direction perpendicular to the plate surface based on the formation of the above-mentioned notch 32. Therefore, as shown in FIG. 4A, the tile mounting rail 10 has a curved shape. The tile mounting rail 10 can be installed along the mounting surface 16 of the above, and as a result, the tile 38 can be mounted along the curved mounting surface 16 as shown in (B). . In (B), the tile 38 has a vertically long shape, and the dovetail groove 26 is formed in the lateral direction on the back surface thereof.

The plate-shaped portion 12 is provided with oblique slits 34 at predetermined intervals along the longitudinal direction. Therefore, as shown in FIG. 5, the tile mounting rail 10 is provided with notches 40. It can also be curved in a direction parallel to the plate surface, which allows the tiles 42 to be mounted in an arch. The slit 34 may be provided so as to extend in the vertical direction.

The embodiment of the present invention has been described in detail above, but this is merely an example, and the present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the invention. is there.
