  By the way, in the case of wooden or steel frame, the indoor wall surface is configured by pasting wallpaper on a gypsum board attached to a stud or torso via a plywood. Therefore, it may not always be easy for an amateur to attach the L-shaped bracket to the indoor wall surface.

  In other words, when the wall surface of the room is made of gypsum board, it is necessary to attach the L-shaped bracket to the position corresponding to the stud and the trunk edge, but in terms of appearance, where the stud and the trunk edge are arranged. It is difficult to determine. Moreover, when the indoor wall surface is comprised with concrete, it is necessary to open the attachment hole for attaching an L-shaped metal fitting to the said concrete, and a dedicated tool is needed depending on the case. Although it is conceivable to attach the L-shaped bracket to the wall surface of the room using an adhesive or double-sided tape, the wall surface is damaged or soiled, and the original state cannot be recovered. As described above, the inner wall panel unit described in the above publication still has room for improvement in terms of both improvement in workability of the inner wall panel unit and restoration of the original shape of the wall surface.

  This invention is made | formed in view of the above, and makes it one of the objectives to provide the technique which contributes to the further improvement of the workability of an inner wall panel unit, and the original state recoverability of a wall surface.

  The inner wall panel unit of the present invention employs the following means in order to achieve the above-described object.

According to the preferable form of the inner wall panel unit which concerns on this invention, the inner wall panel unit for decorating an indoor wall surface is comprised. The inner wall panel unit includes a long base member and a plurality of panels. The base member has a stretchable portion that can be stretched in the longitudinal direction and can maintain a desired stretched state, and at least one ant-shaped tenon extending in the longitudinal direction. The plurality of panels have at least one dovetail groove that can be engaged with the dovetail tenon. The ant-shaped tenon has a first ant-shaped tenon and a second ant-shaped tenon arranged in series with the first ant-shaped tenon across the notch. The panel includes a first panel engaged with the first dovetail tenon through the dovetail groove, a second panel engaged with the second dovetail tenon through the dovetail groove, and a notch. And a third panel to be disposed. Furthermore, the 1st panel has a 1st recessed part or a 1st convex part in the 1st edge part extended in the direction orthogonal to the extending direction of a dovetail groove. Moreover, the 2nd panel has a 2nd recessed part or a 2nd convex part in the 2nd edge part extended in the direction orthogonal to the extending direction of a dovetail groove | channel. The third panel has a third convex portion or a third concave portion that engages with the first concave portion or the first convex portion on the third side portion extending in a direction orthogonal to the extending direction of the dovetail groove. And has a fourth convex part or a fourth concave part engaging with the second concave part or the second convex part on the fourth side part extending in a direction orthogonal to the extending direction of the dovetail groove. . Here, the “indoor wall surface” in the present invention typically corresponds to the indoor wall surface of the side wall connecting the ceiling surface and the floor surface, but preferably includes the ceiling surface. Further, the “first convex portion”, “second convex portion”, “third convex portion”, and “fourth convex portion” in the present invention are integrally formed on the first panel, the second panel, and the third panel, respectively. In addition to the first aspect, the first panel, the second panel, and the third panel are preferably included separately from the first panel, the second panel, and the third panel, and then integrally formed with the first panel, the second panel, and the third panel.

According to the present invention, for example, the base member is disposed in contact with or close to the wall surface on the indoor side of the side wall connecting the ceiling surface and the floor surface, and the expansion / contraction portion of the base member is extended. The base member can be fixed in a state of being stretched between the ceiling surface and the floor surface, and a plurality of panels can be attached to the base member by engaging the dovetail groove of the panel with the dovetail tenon of the base member. Can be installed on. That is, a plurality of panels can be installed at positions facing the indoor wall surface without using fastening members such as bolts and screws. As a result, the resident can easily change the interior of the room. In addition, since the replacement | exchange of a panel is easy, the freedom degree which selects the panel according to a favorite design and a use increases. In addition, since no adhesive or double-sided tape is used when installing the panel, the inner wall panel unit does not drop (peel) from the wall surface due to deterioration over time, and the existing wall surface is not damaged. In addition, since the existing wall surface is not damaged, the original state can be recovered even after the inner wall panel unit is disassembled. Further, since the notch is provided between the first ant tenon and the second ant tenon, for example, the base member is brought into contact with or close to the wall surface on the indoor side of the side wall connecting the ceiling surface and the floor surface. After fixing in a stretched state between the ceiling surface and the floor surface, the panel can be attached to the base member. Thereby, the workability of the inner wall panel unit can be further improved. The first and second panels are attached to the base member by being engaged with the first and second dovetail tenons, and the third panel has the third convex portion or the third concave portion of the first panel. The first and second panels are engaged with the first concave portion or the first convex portion, and the fourth convex portion or the fourth concave portion is engaged with the second concave portion or the second convex portion of the second panel. Therefore, it is possible to achieve both the prevention of the panel from falling off the base member and the improvement of the mounting property of the panel to the base member.

  According to the further form of the inner wall panel unit which concerns on this invention, a base member is a base member, and the base panel is the 1st panel engaged with the 1st dovetail tenon, or the 2nd panel engaged with the 2nd dovetail tenon. It has a holding part that can be temporarily held at a predetermined position in the longitudinal direction.

  According to this embodiment, for example, when the base member is fixed in a state of being stretched between the ceiling surface and the floor surface, the third panel is sandwiched between the first and second panels, thereby being cut into the notch. In the case of attaching the arranged third panel to the base member, the first panel or the second panel to be arranged on the ceiling surface side with the notch interposed therebetween is more ceiling than the notch without being pressed by hand. It can be held in a state of being brought close to the surface side. Thereby, a 3rd panel can be easily installed between a 1st panel and a 2nd panel via a notch. As a result, the attachment property of the panel to the base member can be further improved.

  According to the further form of the inner wall panel unit which concerns on this invention, the holding | maintenance part has the leaf | plate spring arrange | positioned between the base member and the 1st panel or the 2nd panel.

  According to this embodiment, the first panel or the second panel is held at a predetermined position in the longitudinal direction of the base member by using the restoring force (spring force) of the leaf spring that is elastically deformed between the base member and the first panel. can do.

  According to the further form of the inner wall panel unit which concerns on this invention, a notch is the length which becomes more than the length of the longest dovetail groove among the length of each dovetail groove of a 1st, 2nd and 3rd panel. Have

Moreover, the ant-shaped tenon is provided in each of a pair of main pillars. And two dovetail grooves are provided on the panel corresponding to the tenon tenon.

  According to this embodiment, since the base member has a ladder shape, the weight of the base member can be reduced. Thereby, the improvement of the conveyance property of an inner wall panel unit can be aimed at. Further, for example, the base member can be fixed in a state of being stretched between the ceiling surface and the floor surface only by expanding and contracting the adjuster bolt, so that the workability can be improved.

  According to the further form of the inner wall panel unit which concerns on this invention, the some connection beam has the 1st end part beam attached to the 2nd end part of the longitudinal direction of a base member. Moreover, the expansion-contraction part has the 2nd end part beam attached to the 2nd end part of the axial direction of a pair of adjuster bolt.

Here, the “first end beam” and the “second end beam” in the present invention typically correspond to a square bar, but preferably include a flat plate.

  According to the present embodiment, for example, when the base member is fixed in a state where the base member is stretched between the ceiling surface and the floor surface, the first member and the second end beam cause the base member to relatively move from the top surface and the floor surface. Since the surface contact can be made over a wide area, the surface pressure acting on the ceiling surface and the floor surface can be reduced if the tension force on the ceiling surface and the floor surface is the same. Thereby, since the ceiling surface and the floor surface are not damaged, the original state can be recovered even after the inner wall panel unit is disassembled. Further, since the base member can be brought into surface contact with the top surface and the floor surface in a relatively wide area, the base member can be reliably brought into contact with the base provided on the ceiling surface or the floor surface. Thereby, fixation of a base member can be made stable. Furthermore, since the first and second end beams function as joints between the panel and the ceiling surface and between the panel and the floor surface, the design can be improved.

  According to the further form of the inner wall panel unit which concerns on this invention, the base member is comprised so that it can divide | segment into a 1st part and a 2nd part on the boundary in the middle of the longitudinal direction of the said base member.

  According to this form, since a base member can be divided | segmented into a 1st part and a 2nd part, while being able to pack compactly, a conveyance property can be improved.

  According to the further form of the inner wall panel unit which concerns on this invention, the 1st part has the 5th recessed part or the 5th convex part in the 1st end part of the longitudinal direction of the said 1st part. And the 2nd part has the 6th convex part or the 6th recessed part which can be engaged with the 5th recessed part or the 5th convex part in the 1st end of the longitudinal direction of the 2nd part concerned. Here, the “fifth convex portion” and the “sixth convex portion” in the present invention are separately formed from the first portion and the second portion, respectively, in addition to the aspect in which the first portion and the second portion are integrally formed. An embodiment in which the first part and the second part are integrated with each other after molding is suitably included.
