Description

  The present invention relates to a sheet-clad panel in which a sheet-like object is stretched on a surface of a panel attached to a wall surface, a ceiling surface, or the like.

  In order to decorate the wall surface, a method has been proposed in which a sheet-like object having a pattern or pattern drawn on the surface is attached to the wall surface. As this attachment method, in general, a method of adhering a sheet-like material to the wall surface using an adhesive or the like is easy, but an advanced method for adhering the sheet-like material so as not to wrinkle. In many cases, skill is required, and when replacing the sheet material, if the sheet material is peeled off, the adhesive may remain on the wall surface. It was necessary to remove the adhesive, which was time-consuming.

  Therefore, as a method of attaching the sheet-like object to the wall surface without using an adhesive or the like, for example, the edge of the square panel is bent and the peripheral part of the covering material covering the surface of the square panel is this bent part. An apparatus for stopping and tensioning a cover material has been proposed. (For example, refer to Patent Document 1).

  This tensioning device is a rectangular panel with a U-shaped bent part on the back side of the four sides, the surface material is overlapped on the surface, and the periphery of the surface material is bent along the bent part. Further, it is folded back from the edge to the back surface, and the folded portion is fixed elastically and detachably with a stopper.

Japanese Utility Model Publication No. 4-11838

  However, the tensioning device as described above has the following problems. That is, the cover material can be stretched on the surface of the panel without using an adhesive, and the tensioning method is generally used for the work table although the tensioning work and the removal work of the cover material are easy. Spread the sheet-like material on top of it, place a rectangular panel on it, and fix the end of the sheet-like material along the folded part of the rectangular panel with a stopper. The surface of the sheet-like material is not visible, and it is difficult to align the pattern and pattern of the sheet-like material, especially when installing multiple panels side by side on the wall, it is difficult to align the design and pattern of the adjacent sheet-like material Was a problem.

  The present invention is intended to solve the above-described problems and provide a sheet tension panel that can easily adjust the tension position of the sheet material when the sheet material is stretched on the panel. .

In order to achieve the above object, the present invention is configured as follows.
That is, the seat tension panel according to the present invention is a sheet tension panel including a base portion fixed to a wall surface and an attachment portion that is attached to the base portion and on which a sheet-like object is stretched. The end of the shaped object is sandwiched between a receiving part formed on the end surface of the base part and a clamping piece opposed to the receiving part and protruding from the back of the end part of the mounting part. To do.

  According to the present invention, the end portion of the sheet-like material is between the receiving portion formed on the end surface of the base portion and the sandwiching piece that is opposed to the receiving portion and protrudes from the back surface of the end portion of the mounting portion. The base part and the attachment part attached to the base part are placed on a work table and the like, and the sheet-like object is expanded from above, so that the sheet-like object is stretched. Therefore, it is possible to easily align the pattern or pattern of the sheet-like material.

  After the alignment of the sheet-like material, if the end of the sheet-like material is clamped between the receiving portion of the base portion and the clamping piece of the mounting portion, the sheet-like material is stretched on the surface of the mounting portion. Therefore, it is easy to align and stretch the sheet-like material.

  In the seat tension panel according to the present invention, the sandwiching piece protruding from the rear surface of the end portion of the mounting portion is composed of an inner sandwiching piece and an outer sandwiching piece, and the outer sandwiching piece has a lower projection height than the inner sandwiching piece. If it is made, it will become easy to insert a spatula etc. toward an inner side clamping piece, when guiding a sheet-like object toward these clamping pieces using a spatula etc. And while a sheet-like object is firmly clamped between the inner side clamping piece and the receiving part of a base part, it becomes difficult to carry out position shift carelessly by the frictional resistance in a contact location with an outer side clamping piece.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  That is, FIG. 1 is a perspective view showing an embodiment of a sheet-clad panel according to the present invention, FIG. 2 is a cross-sectional view of the main part of FIG. 1, FIG. 3 is an exploded perspective view of the main part of FIG. 1 is a rear view of the main part of FIG. 1, FIG. 5 is an exploded view and an assembled view of the main part of FIG. 1, FIG. 6 is an explanatory view of a method for stretching the sheet-like material, and FIG. It is a fragmentary sectional view shown.

  1 to 4 includes a rectangular base portion 1 and a rectangular attachment portion 2 attached to the base portion 1, and the base portion 1 is interposed via a fixing portion 3. In addition to being fixed to the wall surface W, the surface of the attachment portion 2 is covered with a sheet-like material 4 to be stretched.

  The sheet-like material 4 is intended to cover the surface of the attachment portion 2 and enhance the designability of the sheet-clad panel P according to the present embodiment, and the material thereof is not particularly limited, but cotton, silk, Sheets having strength that does not easily break when stretched, such as natural fibers such as hemp, woven or non-woven fabrics made of synthetic fibers such as polyester, polyethylene, polypropylene, acrylic resin, nylon resin, or films and sheets made of the above synthetic resins Can be used as appropriate.

  As shown in FIGS. 2, 4, and 5, the fixing portion 3 has a fixing member 31 screwed to the wall surface W, and a fixing piece 32 for fixing the base portion 1 to the surface of the fixing member 31. Is formed. In this embodiment, the rectangular base portion 1 is formed to have a rectangular shape in which four fixing portions 3 are combined. However, if the base portion 1 can be fixed, the number of fixing portions 3 is three. The number may be 5 or less.

  The fixing portion 3 is generally composed of a member obtained by cutting a long mold material obtained by extruding a metal or a synthetic resin into an appropriate length. Examples of the metal include an aluminum alloy, a stainless alloy, and a steel material. As the synthetic resin, a polyester resin, a polyamide resin, an AAS resin, an ABS resin, or the like can be used as appropriate depending on the length of the fixing portion 3 and the required strength.

  As shown in FIGS. 2, 4, and 5, the base portions 1 are each formed into a rectangular shape by joining both end portions of four long base members 11, and are fixed on the back side of the base portion 1. In addition to being fixed to 3, the mounting portion 2 is attached on the surface side of the base portion 1.

  Next, a method for fixing the base portion 1 to the fixing portion 3 will be described in detail. In this embodiment, as shown in FIG. 5A, the fixing pieces 32 of the fixing portion 3 protrude substantially vertically along the longitudinal direction of the surface of the fixing member 31 and bend outward. The bent portion 33 is provided. Then, two fitting pieces 12 are juxtaposed in the longitudinal direction of the base member 11 and protrude substantially perpendicularly on the back surface of the base portion 1, and each of the bent portions 13 bends outward like the fixed piece 32. Is formed. Thus, the base portion 1 is fitted by fitting the bent portion 13 of the fitting piece 12 to the bent portion 33 of the fixed piece 32 while pressing each fitting piece 12 from the outer side to the inner side of the fixed piece 32. Can be firmly fixed to the wall surface W via the fixing portion 3 and can be detached.

  In addition, the fixing method of the base part 1 with respect to the fixing | fixed part 3 is not restricted to this form, What is necessary is just to be able to fix the base part 1 to the fixing | fixed part 3 so that fitting and detachment | desorption are possible.

  The mounting portion 2 is formed in a rectangular shape by joining both end portions of four long mounting members 21, as in the base portion 1. As shown in FIGS. 2 is attached to the base 1 on the back side. On the surface of the mounting portion 2, a corner piece 24 is formed upward along the outer peripheral edge portion, and an end portion of the corner piece is formed in a circular arc shape inward. As a result, when the sheet-like material 4 is stretched on the surface of the mounting portion 2, no creases are formed at the corners of the sheet-like material 4, and an unnecessary tensile force is generated on the sheet-like material 4. This is preferable because the risk of breakage is reduced.

  Next, a method for attaching the attachment portion 2 to the base portion 1 will be described in detail. In this embodiment, as shown in FIG. 5A, two locking pieces 14 project substantially vertically in the longitudinal direction of the base member 11 on the surface of the base member 1, and each of them faces inward. A protrusion 15 is formed. Then, on the back surface of the attachment portion 2, two engagement pieces 22 protrude substantially perpendicularly in the longitudinal direction of the attachment member 21, and a recess 23 is formed on each outer surface. Thus, each of the engaging pieces 22 is inserted between the engaging pieces 14 while pressing the inner wall surface of the engaging piece 14 outward, and the projecting portion 15 and the recessed portion 23 are engaged with each other. As shown in FIG. 5B, 2 is attached to the base portion 1 while maintaining a certain distance.

  The method of attaching the attachment portion 2 to the base portion 1 is not limited to this embodiment, and any method may be used as long as the base portion 1 is attached to the attachment portion 2 with a certain interval.

  The base portion 1 is generally composed of a member obtained by cutting a long mold material obtained by extrusion molding a metal or a synthetic resin into an appropriate length. Examples of the metal include an aluminum alloy, a stainless alloy, a steel material, and the like. As the synthetic resin, a polyester resin, a polyamide resin, an AAS resin, an ABS resin, or the like can be used as appropriate depending on the length of the fixing portion 3 and the required strength.

  The mounting portion 2 is generally composed of a member obtained by cutting a long mold material obtained by extrusion molding a metal or a synthetic resin into an appropriate length. Examples of the metal include an aluminum alloy, a stainless alloy, As a synthetic resin such as a steel material, a polyester resin, a polyamide resin, an AAS resin, an ABS resin, or the like can be used as appropriate depending on the length of the fixing portion 3 and the required strength.

  As shown in FIGS. 2 and 3, a plate material 5 is disposed between the base portion 1 and the attachment portion 2. The plate material 5 is formed by cutting a metal plate into a necessary size, and increases the rigidity of the base portion 1 and the mounting portion 2. As the metal plate, for example, an aluminum alloy, stainless steel, or the like Moreover, it can be used according to the size and required rigidity of the plate material 5 such as a composite material formed by bonding these metal plates to both surfaces of an inorganic material or a synthetic resin plate material. In addition, when using the said composite material as a metal plate, the material which has nonflammability is preferable.

  The fixing method of the plate material 5 is not particularly limited. In this embodiment, the plate material 5 is sandwiched between the base portion 1 and the mounting portion 2 and the tucker 7 is attached to the plate material 5 from the surface of the mounting portion 2. Further, it is preferable that the plate member 5 is fixed by penetrating the base portion 1 and is relatively easy to work and can be firmly fixed to the base portion 1 and the mounting portion 2.

  As shown in FIG. 2, a tucker receiver 16 having a substantially L-shaped cross section is provided on the back surface of the base portion 1. Thereby, when an operator handles a sheet tension panel, it is hard to happen that it touches the tip of the core of tucker 7, and it is preferred. In the present embodiment, the plate member 5 is disposed between the base portion 1 and the attachment portion 2, but may be disposed on the surface side of the attachment portion 2.

  As shown in FIGS. 2 and 3, a sound absorbing material 6 is disposed between the surface of the attachment portion 2 and the sheet-like object 4. As the sound absorbing material 6, rock wool, glass wool, felt, foam of resin or concrete, metal fiber bonded through a binder, metal powder or particles, ceramic powder or particles, or short metal fibers are sintered. Those made of a sintered material, foamed malt plain, foamed ceramics, porous ceramics, aggregates of polyester fibers, etc. can be used as needed. The sound absorbing material 6 may be used as it is, or may be used that is molded into a sheet shape in a bag, but may be in a form in which the sound absorbing material 6 is not used.

  Next, a method for sandwiching the sheet-like material 4 will be described. A receiving portion 17 is formed on the outer peripheral end portion of the surface of the base portion 1, and a clamping piece 25 protrudes on the back surface of the mounting portion 2 so as to face the receiving portion 17. It is clamped between the part 17 and the clamping piece 25.

  As shown in FIG. 6, the holding piece 25 of the mounting portion 2 includes an inner holding piece 26 and an outer holding piece 27. The tip of the inner clamping piece 26 is in a state of being substantially in contact with the receiving portion 17 of the base portion 1. Thereby, as shown in FIG. 6B, the sheet-like object 4 is securely held between the inner holding piece 26 and the receiving portion 17. The inner clamping piece 26 is inclined inward. Thereby, when the sandwiched sheet-like object 4 is pulled out, a force acts so as to prevent the sheet-like article 4 from being loosened.

  In addition, the outer sandwiching piece 27 has a lower protruding height than the inner sandwiching piece 26. Accordingly, as shown in FIG. 6A, the sheet-like object 4 is arranged downward from the outer holding piece 27, and the sheet-like object 4 is moved to the inner holding piece 26 and the outer holding piece 27 using a spatula or the like. When guiding between the receiving portion 17 and the spatula, it is easy to insert a spatula or the like to the back, which is preferable because the sheet-like material 4 can be easily guided inward. In general, the thicker the sheet-like material 4 is, the larger the clamping force required for tensioning is. Therefore, as shown in FIG. What is necessary is just to clamp between the piece 26 and the receiving part 17, and as shown in FIG. 7, the comparatively thick sheet-like object 4 is clamped between the inner side clamping piece 26 and the outer side clamping piece 27, and the receiving part 17. By this, it can clamp more firmly. The protruding height of the outer clamping piece 27 can be set as appropriate according to the thickness of the sheet-like material 4 and the necessary clamping force when clamping the sheet-like material 4.

  And the front-end | tip of the outer side clamping piece 27 is divided into two forks. Thereby, when the sheet-like material 4 is clamped, the frictional force acting at the tips of the sheet-like material 4 and the outer clamping piece 27 is increased, and the sheet-like material 4 is less likely to be unintentionally displaced. In this embodiment, the surface of the receiving portion 17 of the base portion 1 is smooth and is preferable because the sheet-like material 4 can be easily guided inward with a spatula or the like. The protrusions may be formed in the direction to increase the frictional force generated between the sheet-like objects 4 so that the sheet-like objects 4 can be clamped more firmly.

  On the surface of the mounting portion 2, a corner piece 24 is formed upward along the outer peripheral edge portion, and an end portion of the corner piece is formed in a circular arc shape inward. As a result, when the sheet-like material 4 is stretched on the surface of the mounting portion 2, no creases are formed at the corners of the sheet-like material 4, and an unnecessary tensile force is generated on the sheet-like material 4. This is preferable because the risk of breakage is reduced.

  When an elastic material is used as the inner sandwiching piece 26 and the outer sandwiching piece 27 of the mounting portion 2, the operation of sandwiching the sheet-like object 4 becomes easy and the sheet-like article 4 can be sandwiched with an unnecessarily strong force. This is preferable because tearing and the like are less likely to occur. Elastic materials include natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, ethylene propylene terpolymer, urethane resin, polyisobutylene resin, polyethylene resin, ethylene vinyl acetate copolymer, silicone resin, soft resin And required strength and sheet such as hard vinyl chloride resin, styrene-butadiene, polyolefin, polyester, polyvinyl chloride, polyurethane, polyamide, etc. What produces the clamping force required in order to clamp the state thing 4 can be used suitably.

  When the sheet-like material 4 is stretched, first, the base portion 1 and the attachment portion 2 attached to the base portion 1 are placed on the work table, and the sheet-like material 4 is spread on the work sheet. What is necessary is just to clamp the edge part of the shaped article 4 as mentioned above, and it is preferable because it can be stretched while adjusting the position of the pattern or design of the sheet-like article 4. In particular, when the sheet tension panel P according to the present embodiment is fixed to the wall surface W so as to be adjacent in the vertical direction or the horizontal direction, the position adjustment of the pattern and the pattern of the adjacent sheet-like object 4 is facilitated and adjacent. Since the pattern and design of the sheet-like material 4 can be continued, it is preferable.

  And since the base part 1 can be fitted and detached with respect to the fixed part 3, in the sheet tension panel P fixed to the wall surface W, a part of the sheet-like object 4 is scratched or soiled. Even if it occurs, it is preferable to remove only the sheet tension panel P of that portion and replace the sheet-like material 4 and to easily align the pattern and design of the sheet-like material 4 at that time.

Next, the embodiment shown in FIG. 8 will be described in detail.
In the base part 1 and the fixing part 3 shown in FIG. 5, two fitting pieces 12 projecting from the base member 11 of the base part 1 and two fixing pieces projecting from the fixing member 31 of the fixing part 3. 32 are fitted to each other, and the base portion 1 is fixed to the fixing portion 3. On the other hand, in the form shown in FIG. 8, the engaging ridge 34 that protrudes from the fixing member 31 toward the base member 11 is formed in the concave groove 18 in which the inlet / outlet is formed on the fixing member 3 side in the base member 11. Only the point of insertion is different, and the other points are the same as those shown in FIG.

  That is, in the base portion 1 and the fixing portion 3 according to this embodiment, the side wall surface of the concave groove 18 of the base member 11 is provided with the concave and convex ridges 19 having a cross-sectional mountain shape along the longitudinal direction. On both side surfaces of the mating ridge 34, concavo-convex ridges 35 having the same form as the concave grooves are provided. When the engaging ridge 34 is inserted into the concave groove 18, the concave and convex ridges 19 and 35 are engaged with each other, the engaging ridge 34 is locked to the concave groove 18, and the base portion 1 is fixed to the fixing portion 3. . Thereby, compared with the form shown by FIG. 5, the clearance gap formed between the base member 11 and the fixing member 31 can be narrowed, and space saving can be achieved. Further, by providing a plurality of projections and depressions on the projections and depressions 19 and 35, the position where the projections and depressions 19 and 35 are engaged can be adjusted, and the gap between the fixing member 31 and the base member 31 can be set as appropriate. .

Next, the embodiment shown in FIG. 9 will be described in detail.
In the form shown in FIG. 5, the two locking pieces 14 protruding from the base member 11 of the base portion 1 are inserted into the engaging pieces 22 protruding from the mounting member 21 of the mounting portion 2, and the mounting portion 2 is attached to the base portion 1. On the other hand, in the form shown in FIG. 9, the base portion 1 and the attachment portion 2 are integrally formed via a connecting piece 8 that can be bent, and the attachment portion 2 is folded toward the base portion 1. As a result, the engaging portions 81 and 82 of the base portion 1 and the attaching portion 2 are engaged with each other, so that the attaching portion 2 is attached to the base portion 1.

  That is, in this embodiment, as shown in FIG. 10, the base portion 1 and the attachment portion 2 have a sheet-like material 4 sandwiched at one side end and a connecting piece that can be bent at the other side end. 8 and are integrally formed. The base member 11 of the base portion 1 has an engaging portion 81 that protrudes toward the mounting portion 2, and the mounting member 21 of the mounting portion 2 has an engaging portion 82 that protrudes toward the base portion 1. The engaging portions 81 and 82 are formed with flange portions 83 and 84 at their tips. Then, as shown in (a), by folding the attachment portion 2 toward the base portion 1 with the connecting piece 8 as an axis, the flange portions 83 and 84 are engaged with each other as shown in (b), and the attachment portion 2 is attached to the base part 1. At this time, folding the attachment portion 2 toward the base portion 1 represents a relative movement, and the base portion 1 may be folded toward the attachment portion 2. The engaging portions 81 and 82 may use the form shown in FIG. 5, or may use the form in which the base part 1 shown in FIG. When the object 4 is clamped, the clamped state is not loosened, and it is sufficient that the sheet-like object 4 does not have problems such as looseness.

  In the form shown in FIG. 5, two fitting pieces 12 projecting from the base member 11 of the base portion 1 toward the fixing portion 3, and from the fixing member 31 of the fixing portion 3 toward the base portion 1. The two fixed pieces 32 protruding in this manner are fitted to each other. On the other hand, in the embodiment shown in FIG. 9, the engagement protrusion 85 formed on the base member 11 is inserted into the engagement groove 86 formed on the fixing member 3 and locked, and the fixing member The base part 1 is fixed to the fixing part 3 by combining the form in which 31 and the base member 11 are coupled via the surface fasteners 87 and 88 provided respectively.

  The engaging protrusion 85 is provided with a bulging portion having a rhombus-shaped tip, and the locking groove 86 is formed with an extending portion extending obliquely downward from the end portion of the side wall surface toward the opposite side wall surface. In addition, the distance between the engagement projections 85 is formed so that the distance between the engagement protrusions 85 is shortened, and the end portions of the engagement protrusions 85 are formed in a substantially square shape. The locking groove 86 is inserted and locked between the extended portions.

  That is, in the form of FIG. 9, first, the engaging protrusion 85 formed on the base portion 1 is inserted into the locking groove 86 formed on the fixing portion 3, and then the surface fasteners 87, 88 are pasted together. By doing so, the surface fasteners 87 and 88 can absorb construction errors and processing errors of the fixing portion 3, so that the base portion 1 can be more easily fixed to the fixing portion 3. About another point, it is the same as that of the form shown by FIG.

  The connection piece 8 is generally made of an elastic material similar to that of the holding piece 25 and may be bonded to the base member 1 or the attachment member 2 with an adhesive or the like. Is a thermoplastic resin, it is more preferable that a resin compatible with these can be used for extrusion molding integrally with the base member 1 and the mounting member 2 and the above-described bonding operation is unnecessary. . At this time, the sandwiching piece 25 may be integrally extruded.

  The form shown in FIG. 11 shows a deformation of the sheet tension panel P according to the present embodiment, and the cover material 9 is attached to the side end of the sheet tension panel P. The cover member 7 is formed in a substantially flat plate shape, covers the side end portions of the attachment portion 2, the base portion 1, and the fixing portion 3, and two flange portions 91 and 92 that face each other toward the base portion 2 side. Is protruded and inserted and fixed between the base portion 2 and the fixing portion 3. Accordingly, when a plurality of sheet tension panels P are connected to the wall surface W, the sheet tension panel can be viewed from the side by attaching the cover material 9 to an end portion where the sheet tension panels P are not adjacent to each other. P can be covered to improve the design. Moreover, the lower part of the cover piece 9 is bent in the cross-section arc shape toward the outer side. This makes it easier to remove dust when dust accumulates after installation than when the end is formed flat. Furthermore, the upper part of the cover material 9 is bent in a cross-section arc shape inwardly along the corner piece 24 of the attachment part 2. Thereby, even if a gap is generated between the sheet member 4 and the cover piece 9, even if this gap is covered, it becomes difficult to stand up, and the design properties when the sheet-stretched panel P is viewed from the front can be improved.

  The cover member 9 is locked by forming a hook-like shape protruding outward at the end of the cover member 9 and inserting the cover member 9 between the base portion 2 and the fixing portion 3 and pressing each of them. It may be made by claw portions projecting inward on the back surface of the base member 21 of the base portion 2 and the surface of the fixing member 31 of the fixing portion 3 and pressing the flange portions 91 and 92, respectively. In other words, it may be a combination of these, as long as the cover piece is not easily removed.

  According to the present invention, when a decorative panel is fixed to a wall surface, the decorative panel is easily attached and detached, and is firmly fixed. Therefore, the decorative panel is suitably used for, for example, surface decoration of an indoor wall surface of an existing building or redesigning a wall surface. In addition, if a joint member in which a retaining groove is formed is used, a shelf board or the like can be fixed on the decorative panel, so that it can be suitably used for a wall surface of a store.
