Description

DETAILED DESCRIPTION OF THE INVENTION The present invention does not attach curtain materials such as lining cloth directly to the wall surface, but instead inserts the straight edges folded inward at 180 degrees into the insertion grooves of the fastening pieces. A swinging protrusion piece in which a fastening piece is pivotally supported on the front side of a mounting plate fixed to a wall surface so that the attachment piece can swing freely between three positions: a protruding state toward the front surface and a parallel state in contact with the front surface. When inserting and connecting the straight edge folded inward at 180 degrees to the free end edge of the holder and inserting and removing it into the insertion groove of the fastening piece, the swinging protrusion protrudes together with the fastening piece. The curtain material is swung in a parallel state to create sufficient slack in the curtain material, and at the same time as the swinging protrusions are swung to a parallel state, the curtain material is automatically tensioned and stretched against the wall surface, and the tension is maintained. The purpose is to provide a device that facilitates the attachment and replacement of curtain materials to walls.

An embodiment of the invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a mounting piece, and a supporting piece 6 has a shaft-like projection 8 and a hook 9 provided horizontally in parallel on the upper and lower sides of the front surface.
A frame part 2 and a mounting plate 3 are provided, each having a window hole 4 through which the window hole 4 is passed from the back surface, and a mounting plate 3 is provided. An engaging recess 5 into which a flange 7 of a frame-shaped support piece 6 is inserted is formed as shown in FIG. 2.

The support piece 6 is provided with a shaft-shaped protrusion 8 whose left and right ends are integrally connected to the frame-shaped edges 6a on both sides, and a latch hook 9 below the protrusion. A hook protrusion 10 is provided that projects from the top.

Reference numeral 11 denotes a swinging protrusion formed by a width that fits between the frame-shaped edges 6a on both sides of the support piece 6, and has a semicircular cross section that fits into the back surface of the upper part with a little force from the front surface of the shaft-like protrusion 8. A shaft fitting groove 13 is provided.

This swinging protrusion 11 has a protruding state in which the free end edge 12 of the lower end protrudes to the front of the mounting piece 1 as shown by the chain line in FIG. 3, and is provided with a protruding hook 14 on the back surface that engages with the hook 9 from below when in the parallel posture.

The free end edge 12 is arranged to be substantially aligned with the lower end of the mounting plate 3 when in a parallel state, and several engaging protrusions 16 in the left and right direction are provided on the inner and outer surfaces of the free end edge 12. Then, the engaging plate 15 is formed.

The engagement plate 15 is slightly concave on both the front and rear surfaces to reduce its thickness.

Reference numeral 17 indicates a fastening piece whose length in the width direction is significantly increased.

The front plate 18 of the fastening piece 17 has a short length in the vertical direction perpendicular to the width direction, and is curved so that the lower edge is bent toward the back surface. Three parallel protruding pieces 19 and 20 are provided to extend in the length direction, and the protruding strips project obliquely from the lower protruding piece 19 to the back side of the front plate 18 in a substantially parallel manner. 21 is provided to form an insertion groove 22 whose lower side is open, and from the upper protruding piece 20, a protruding piece 23 is provided that protrudes upward on the back surface of the front plate 18, and the engaging plate of the swinging protruding piece 11 is provided. 15, a fitting groove 24 is formed into which the free end edge 12 is fitted.

In this embodiment, the insertion groove 22 is inclined slightly rearward.

As shown in FIGS. 3 and 4, the above-mentioned mounting piece 1 is a support piece 6 which is attached to the upper and lower parts of the indoor wall surface 31 and has a shaft-fitting groove fitted into the shaft-like protrusion 8 of the support piece 6. Folds 33 are applied inwardly to the upper and lower straight edges of a base material 32, such as a lining cloth made of cloth or synthetic resin, which is cut to support the movable projection piece 11 and lined on the interior wall surface 31, The insertion engagement piece 34 is glued to the inner surface of the fold, and the fold 33 and the insertion engagement piece 34 are inserted into the insertion groove 22 of the fastening piece 17. As shown by the chain line in the figure, the free end edge 12 is in a swinging position protruding from the front surface of the mounting piece 1, and the fitting groove 24 of the fastening piece 17 is inserted and connected to the engagement plate 15, and then the upper mounting piece 1 From the front surface of the base material 32, move each swinging protrusion so that the free end of the swinging protrusion 11 is upward, and the free end of the swinging protrusion 11 is downward for the lower attachment piece 1 that has been folded. Press 11 to rock.

At that time, the base material 32 is tensed in the vertical direction and the indoor wall surface 31
The mounting piece 1, the swinging protrusion 11. The fastening piece 17 and the like are hidden on the back surface of the base material 32.

This tension holding device can be provided not only above and below the wall surface 31 but also on the left and right sides.

Further, it is also possible to fix a fastening piece that does not have the swinging protrusion 11 on one of the upper and lower sides or the left and right sides.

As clarified by the description of the above embodiments, the present invention includes a fixing piece 17 for inserting an edge of a base material such as lining cloth into the free edge 12 of the swinging protrusion 11, and connecting the swinging protrusion to the free edge 12 of the swinging protrusion. Piece 11
By swinging to two positions, in one swinging position, the base material is relaxed and folded, allowing for free installation and replacement, and in the other swinging position, the base material can be tensioned and stretched in front of the wall surface. When the tension is applied, the mounting piece 1, the swinging protrusion 11. Since all of the fastening pieces 17 are hidden on the back surface of the base material 32, there is an inventive step in that the attachment of the lining base material to the wall surface, replacement, etc. can be made extremely easy.
