A technique of attaching a cloth sheet to a ceiling is generally known as an interior decoration. An example is (A)
No. 57-111913 or (B) Japanese Utility Model Laid-Open No. 63-117809.

In the above-mentioned (A) publication, a sheet is projected along a ceiling surface,
Moreover, it is provided so that it can be stored in a part of the ceiling. Further, (B) gazette relates to a peripheral edge that supports an edge portion of a sheet stretched on a ceiling surface.

[Problems to be solved by the device]

The technique of each of the above examples stretches the sheet over the entire ceiling surface, and the wider the ceiling surface, the more difficult it is to attach the sheet with tension over the entire surface. As such, it is consciously attached with a flexure.

In view of the above problems, the present invention has been developed with the object of being able to stretch the seat over the entire surface in a tensioned state.

[Means for Solving the Problems]

The solution according to the present invention is a ceiling panel in which a sheet is attached to the lower surface of a frame body formed by a vertical frame and a horizontal frame made of a hollow shape member. In addition, the core which holds the side edge portion of the sheet inserted into the vertical frame while at the same time protruding the side portion of the sheet into the vertical frame through the slit provided in the lower surface of the vertical frame over the entire length in the longitudinal direction thereof. Is provided so that the sheet can be attracted in the direction in which the sheet is stuck, and the gist is that both ends of the sheet are fixed to the concave grooves formed in the horizontal frame by the fastening material.

As still another solution, one fastener stringer of the slide fastener is fixed to the side portion of the seat along the longitudinal direction, and the other fastener stringer is fixed to the core provided in the vertical frame through the slit of the vertical frame. The gist is that the side edge of the seat is detachably fixed to the vertical frame.

[Action]

Therefore, the frame body is assembled by the vertical and horizontal frames, the core is inserted into the vertical frame, and then both side portions of the sheet are fitted into the core through the slits of the vertical frame and fixed, and at least one core is separated from each other. The sheet is stretched in a tensioned state by pulling the sheet in the direction to keep the sheet in a tensioned state, and further, by fixing both ends of the sheet in the concave grooves of the horizontal frame with a fastening material.

Also, if the slide fastener is attached to the seat, one fastener stringer should be attached to the core, select the sheet with the desired color pattern and attach via the slide fastener, even when replacing the seat It can be easily replaced by opening and closing the slide fastener.

〔Example〕

The present invention will be described in detail. As shown in FIG. 1, a plurality of T-bars 1 ... Form a ceiling substrate, and the ceiling panel according to the present invention is provided between the flanges 2 ... of the T-bar 1. Is to be placed.

The ceiling panel is a sheet 3 as shown in FIGS. 1 to 3.
The sheet 3 includes a vertical frame 4, a horizontal frame 5, and a frame body 7 formed of an inner bar 6, and a core 8 that is inserted into the vertical frame 4, and the sheet 3 has a smoke-proof toughness. It is made of natural cloth and is provided with ridges 9 and 9 on both side edges. As shown in FIG. 3 (A), the vertical frame 4 has a pair of connecting walls 12 and 13 between an upper wall 10 and a lower wall 11 which are parallel to each other, and the connecting wall 13 is provided outside the one connecting wall 13. An engaging groove 14 is provided in a stepped manner at a lower portion of the vertical frame 4, and a slit 15 is provided between the lower wall 11 and one connecting wall 13 over the entire length of the vertical frame 4 in the longitudinal direction. As shown in FIG. 3 (B), the horizontal frame 5 is made of a hollow shape member and has a locking groove 16 similar to that of the vertical frame 4 on one side thereof, and a concave groove having an open upper surface on the opposite side. With 17 provided, the locking groove from which the vertical frame 4 projects
It is formed at the same height as 14 heights. As shown in FIG. 3 (C), the core 8 is made of a hollow material having a rectangular cross section,
The vertical wall 18 on one side is formed to be thicker than the other, and a slit 19 similar to the vertical frame 4 is provided in the lower corner portion. In particular, this slit 19 is about the thickness of the sheet 3, The width is such that the ridges 9 cannot pass through, and both connecting walls of the vertical frame 4 are provided.
It is formed so that it can be inserted between 12 and 13. Further, as shown in FIG. 3 (D), the middle crosspiece 6 is made of a hollow material having a quadrangular cross section.

Therefore, as shown in FIG. 4, the vertical and horizontal frames 4 and 5 are assembled by notching and engaging each of the locking grooves 14 and 16 of the vertical and horizontal frames 4 and 16 at a right angle, and connecting the L-shaped connecting pieces 20 to each other. Locking groove 14,1
Inserted in a state of being crimped to 6 to form a frame shape,
Is notched at the tip as shown by the chain double-dashed line in FIG. 3 (A), and its upper surface is brought into contact with the upper wall 10 of the vertical frame 4 and screwed,
The lower surface of the vertical frame 4 is assembled so as to be slightly above the lower surface of the locking groove 14 of the vertical frame 4. The thick vertical wall 18 of the core 8 is inserted into the vertical frame 4 toward the outside of the frame, and several screw rods 21 inserted through the outer connecting wall 12 of the vertical frame 4 are attached to the core 8. The spring 22 is screwed to the thick vertical wall 18, and the spring 22 is interposed between the head of the screw rod 21 and the connecting wall 12. When the frame body 7 is formed by the vertical and horizontal frames 4 and 5, it is not limited to the means using the L-shaped connecting piece 20, and other known means may be used for assembly. The screw rod 21 may be attached to both the left and right cores 8, but may be attached to one core 8.

The sheet 3 is attached to the frame body 7 assembled as described above by inserting the side edge portion of the sheet 3 into the slit 19 of the core 8 through the slit 15 of the vertical frame 4 from one end. Is held by the ridges 9 so as not to slip out. Therefore, the sheet 3 is tensioned and attached by pulling the core 8 to the outside of the frame by the screw rods 21. Both ends of the seat 3 are extended longer than the horizontal frame 5, and the end of the seat 3 is extended to the horizontal frame 5 as shown in FIG. 3 (B).
It is inverted so as to be wound around the outer surface of the, and the inverted portion is press-fitted and fixed in the concave groove 17 together with the fastening material 23 such as a bead. As shown in FIG. 4 and FIG. 5, the vertical and horizontal frames 4, 5 are partially overlapped with each other, and the corners of the frames are vacant portions, and the ridges of the seat 3 are in the vacant portions. 9
Since the sheet protrudes and is inverted, the sheet 3 does not stick to the corner of the sheet 3 and is smoothly inverted and fixed. Further, since the middle rail 6 is provided above the slit 15 of the vertical frame 4, the sheet 3 stretched as described above is
Therefore, the contour of the middle crosspiece 6 does not stick out to the sheet 3 when it is looked up from below, and can be attached in a good appearance.

Further, as clearly shown in FIGS. 2 and 3 (A) and (B), in particular, FIG. 2, the joint portion of the vertical frame 4 and the horizontal frame 5 is such that the lower wall of the horizontal frame 5 is the vertical frame 4. Since the slit 15 of the vertical frame 4 is flush with the lower wall of the stop groove 14 and is not blocked by the end of the horizontal frame 5, the slit 15 does not need to be disassembled. The seat 3 can be freely attached and detached. Therefore, when the seat 3 has become dirty over the years, or when it is desired to re-attach the seat when the interior is changed, after removing the fastening member 23 from the groove 17 of the lateral frame 5 and releasing both ends of the seat 3, , The core 8 is moved to the inside of the frame by the screw rods 21 to release the tension of the sheet 3, and then the sheet 3 is pulled out from the frame while sliding the sheet 3 along the longitudinal direction of the slit 15. After that, the replacement sheet may be attached to the inside of the frame body 7 in the same manner as described above, contrary to the case of the extraction.

Next, in the example shown in FIG. 6, the slit 15 of the vertical frame 4 is formed in the lower wall 11
In this case, the core 8 is pulled inside the frame by a screw rod 21 which is inserted through the locking groove 14 and is tensioned. Other structures are the same as those in the above-mentioned example.

Further, in the example shown in FIG. 7 and subsequent figures, the seat 3 is formed so as to be attachable to and detachable from the frame body 7 via the slide fastener 24. The slide fastener 24 is as shown in FIG. 9 and FIG. , The left and right fastener stringers 26, 27 can be separated by the separable bottom end stop 25, and one fastener stringer 26 is fixed to the back surface of the side portion of the seat 3 by sewing or adhesive means, and the other fastener stringer 27 is attached. A ridge portion 9 is provided on the side edge and is fixed to the core 8 by passing through both slits 15 and 19 in the same manner as in the above-mentioned example, and is connected by a separable bottom end stop 25 and both fastener stringers 26, 26 by a slider 28. It is closed by engaging 27.

Further, as shown in FIG. 7, the vertical frame 4 used in this example has a downward groove 29 on the outer surface thereof, and the side edge portion extending from the portion of the seat 3 where the fastener stringer 26 is attached is provided with a fastening member 23 such as a bead. It is fixed to the downward groove 29. Further, the horizontal frame 5 is assembled in the frame body 7 by assembling with the vertical frame 4 in the same manner as in the above-mentioned example, but a stepped notch 30 is formed at the lower end of the horizontal frame 5 as shown in FIG. Keep it. The notch 30 is formed so that the slide fastener 24 attached to the seat 3 fits therein and no step is formed at the lateral frame 5. Other structures are the same as the above-mentioned example.

Therefore, in the seat-clad ceiling panel of this example, once the fastener stringer 27 is fixed to the core 8, the seat can be replaced by opening and closing the slide fastener, so that the seat can be easily attached to and detached from the frame. . Moreover, in the case where this slide fastener is used, a sheet made of a material which is relatively difficult to attach in the above example in which the sheet is directly attached to the frame can be easily attached. By the way, if the sheet is thick and rigid, it takes a lot of time to pass through the slit, and the sheet may be damaged during sliding with the slit end. On the contrary, if the sheet is a thin sheet and is made of a material that is slippery, the operation through the slit is easy, but there is a possibility that the ridge portion 9 of the sheet is crushed and slips out of the core during the tensioning operation with the screw rod. In some cases, the sheet cannot be attached in a tense state, but if the slide fastener is used as described above, the sheet made of the above-mentioned special material can be surely attached in a tense state.

Further, the example shown in FIG. 11 is a modification of the example shown in FIG. 7, in which the vertical frame 4 is replaced with the downward groove 29 and the lateral groove 31 is formed.
The side edge portion of the seat 3 is fixed to the lateral groove 31 by a bead tightening member 23.

Further, in the example shown in FIG. 12, a plurality of vertical frames 4 constituting the frame body 7 are sequentially joined through a strip-shaped vertical connecting piece 32 fitted in each vertical frame in the longitudinal direction to form a horizontal frame 5 and a middle frame. The long frame 7 is formed by the crosspieces 6, and is provided as a panel that is seamless in the longitudinal direction of the ceiling. Other structures are the same as those in each of the above examples.

With the panel according to this example, the ceiling can be covered from end to end, so that the sheet has no seam and can be structurally finished as a ceiling having a different design regardless of the color pattern of the sheet.

[Effect of device]

The sheet-tensioned ceiling panel according to the present invention is to attach a sheet to the lower surface of the frame body, and insert the side portion of the sheet into the vertical frame through the slit and fix it to the core provided in the vertical frame. The core is pulled to attach the sheet, and the end of the sheet is fixed in the concave groove of the horizontal frame through the fastening material.It is easy to insert the side part of the sheet into the vertical frame. By the operation of pulling the core and the operation of fixing the end portion of the sheet to the concave groove of the horizontal frame, the sheet can be tightly attached to the frame body without bending, and the attachment operation can be facilitated. Furthermore, since the sheet is attached to the frame, it is possible to bring each member to the site and assemble it there.In particular, the sheet is selected and used according to the taste of the customer and the atmosphere of the room. However, the selection can be easily accommodated.

Also, when the seat is replaced with a new one when it has become dirty over the years or for the purpose of changing the interior, etc., while opening both ends of the seat from the groove of the horizontal frame,
After the seat tension is loosened and the seat is taken out of the vertical frame and the core, a new seat may be stretched as described above, so that the seat can be easily reattached.

Also, if the seat is attached with a slide fastener, the seat can be reattached by opening and closing the slide fastener, so that the same effect as the above-mentioned effect can be obtained, and the seat comes into contact with the slit of the vertical frame when the seat is attached and detached. Since there is no such thing, even if the sheet is made of a material that is easily scratched, you can easily and neatly stretch it on the frame,
Its utility value is further enhanced. Moreover, it is not necessary to release the connection part with the frame of the seat when re-seat the seat,
Since it can be replaced by opening and closing the slide fastener, the seat can be easily replaced in a short period of time when the seat becomes dirty or when the interior is changed.
