The following is recommended. Moreover, the dimension L3 is good to set it as 0.25H or less. Furthermore, the dimension L3 is preferably 0.125H or less. The dimension L3 may be appropriately set in consideration of easiness of cutting the wallpaper pasted on the first wall surface 80 and the second wall surface 81 described later, for example.

  In the embodiment, the first surface 48 is an inclined plane, and the second surface 49 is a horizontal plane. However, the first surface 48 may be an inclined surface having a shape different from the inclined plane. For example, the first surface 48 may be an inclined curved surface. When the first surface 48 is an inclined curved surface, the inclined curved surface described above may be a convex curved surface or a concave curved surface. That is, the first surface 48 includes various shapes of inclined surfaces that are inclined toward the ends of the first wall surface 80 and the second wall surface 81 in the height direction.

  The 2nd engaging part 50 is provided in the back surface (back surface) of the coating | coated member 40 (refer FIG. 7). The back surface of the covering member 40 is a surface on the mounting side in the attaching / detaching direction. Furthermore, the second engaging portion 50 is formed at a protruding corner boundary portion where the first covering portion 42 and the second covering portion 44 are in contact with each other. In the covering member 40, the same number of second engaging portions 50 as the first engaging portions 24 are provided corresponding to the positions of the first engaging portions 24 in the support member 20. As described above, in the corner member 10, the support member 20 includes the two first engaging portions 24 (see FIG. 4). Therefore, in the covering member 40, the two second engaging portions 50 are respectively provided in the state where they correspond to the two first engaging portions 24 at the aforementioned protruding corner boundary portion.

  The second engaging portion 50 engages with the first engaging portion 24 (see FIG. 8). The second engaging portion 50 is provided with two beam portions 52 on the mounting side in the attaching / detaching direction. In the second engaging portion 50, the two beam portions 52 are separated by a predetermined amount in the height direction. The two beam portions 52 are elastically deformed in the height direction. A claw portion 54 is formed at the tip portion on the mounting side of the beam portion 52 in the attaching / detaching direction. Of the two beam portions 52, in the beam portion 52 provided on the center side in the height direction, the claw portion 54 has a shape protruding toward the center side in the height direction. Of the two beam portions 52, in the beam portion 52 provided on the end side in the height direction, the claw portion 54 has a shape protruding toward the end side in the height direction. In a state where the second engagement portion 50 is fitted in the fitting hole as the first engagement portion 24, each claw portion 54 of the two beam portions 52 is caught by the step portion 26.

  In the corner member 10, when the support member 20 and the covering member 40 are separated, the covering member 40 is pulled to the separation side in the attaching / detaching direction. In the second engagement portion 50, the two beam portions 52 are elastically deformed to the side in the height direction in which they approach each other. In the supporting member 20 and the covering member 40, the two sets of the first engaging portion 24 and the second engaging portion 50 release the catches of the step portion 26 and the claw portion 54, respectively. Accordingly, the support member 20 and the covering member 40 are separated.

<Effect of embodiment>
According to the embodiment, the following effects can be obtained.

  (1) The corner member 10 includes a support member 20 and a covering member 40 (see FIG. 3). The support member 20 is accommodated in the accommodation space S (see FIG. 2). The support member 20 is provided with a first engagement portion 24 (see FIGS. 4 and 5). The covering member 40 is provided with a second engaging portion 50 (see FIG. 7). In the corner member 10, the first engaging portion 24 and the second engaging portion 50 are engaged (see FIGS. 3 and 8).

  At the construction site, the first decorative member 90 is cut according to the dimension of the first wall surface 80, and the second decorative member 95 is cut according to the dimension of the second wall surface 81. Thereafter, the first decorative member 90 is fixed to the first wall surface 80 and the second decorative member 95 is fixed to the second wall surface 81. The first decorative member 90 and the second decorative member 95 are fixed so that the first decorative member 90 and the second decorative member 95 do not float from the first wall surface 80 and the second wall surface 81, respectively, and do not fall off. It is done by the method. Therefore, for example, nails may be used to fix the first decorative member 90 and the second decorative member 95. When a nail is struck on the first end portion 91 of the first decorative member 90, the first decorative member 90 is firmly fixed to the first wall surface 80 at the first end portion 91. When a nail is struck on the second end portion 96 of the second decorative member 95, the second decorative member 95 is firmly fixed to the second wall surface 81 at the second end portion 96. As a result, in a known corner member different from the corner member 10, a predetermined portion of the known corner member is provided between the first wall surface 80 and the first end portion 91 and between the second wall surface 81 and the second end portion 96. In some cases, it may be difficult to insert each of the two.

  According to the corner member 10, the covering member 40 can be supported by the support member 20 accommodated in the accommodation space S. The corner member 10 can be easily installed in the entrance corner 82. As described above, the housing space S is formed by providing the first decorative member 90 and the second decorative member 95 on the first wall surface 80 and the second wall surface 81, respectively. Thereafter, the support member 20 is accommodated in the accommodation space S, and the covering member 40 is mounted on the support member 20 accommodated in the accommodation space S. That is, the second engagement portion 50 of the covering member 40 is engaged with the first engagement portion 24 of the support member 20 accommodated in the accommodation space S. Work on the construction site can be simplified. The covering member 40 can cover the first end 91, the second end 96, and the accommodation space S.

  (2) The support member 20 is provided with a first contact portion 28 and a second contact portion 30 (see FIG. 4). The first contact portion 28 is provided closer to the first end surface 92 than the base portion 22 and is in contact with the first end surface 92 (see FIGS. 2 and 6). The 2nd contact part 30 is provided in the 2nd end surface 97 side from the base 22, and contact | connects the 2nd end surface 97 (refer FIG.2 and FIG.6). Therefore, the support member 20 accommodated in the accommodation space S is inserted into the corner by the reaction force from the first end surface 92 acting on the first contact portion 28 and the reaction force from the second end surface 97 acting on the second contact portion 30. 82 can be fixed.

  By engaging the first engagement portion 24 and the second engagement portion 50, the support member 20 can be pulled to the detachment side in the attachment / detachment direction. In other words, the covering member 40 can be pulled toward the mounting side in the attaching / detaching direction by engaging the first engaging portion 24 and the second engaging portion 50. The tensile force on the support member 20 and the covering member 40 is adjusted according to the dimension L4 (see FIG. 8) of the second engagement portion 50 in the attaching / detaching direction. The dimension L4 of the second engagement part 50 is a dimension from the separation side end of the second engagement part 50 in the attaching / detaching direction to the root of the claw part 54. Also by this tensile force, the first contact portion 28 can be pressed against the first end surface 92, and the second contact portion 30 can be pressed against the second end surface 97. With this tensile force, the first covering portion 42 can be pressed against the first end portion 91, and the second covering portion 44 can be pressed against the second end portion 96.

  (3) The support member 20 is provided with a first deformable portion 32 and a second deformable portion 34 (see FIG. 4). The first deformation part 32 is provided in the first contact part 28. The first deforming portion 32 deforms the first contact portion 28 into a form corresponding to the interval A between the second wall surface 81 and the first end surface 92. The second deforming part 34 is provided in the second contact part 30. The second deforming portion 34 deforms the second contact portion 30 into a form corresponding to the interval B between the first wall surface 80 and the second end surface 97.

  Therefore, the support member 20 can have flexibility with respect to the size of the accommodation space S. As described above, at the construction site, the first decorative member 90 is cut and the second decorative member 95 is cut. Therefore, an error due to cutting may occur in each dimension of the first decorative member 90 and the second decorative member 95. Therefore, in the construction site, it is assumed that the distances A and B (see FIG. 2) vary depending on the dimensions of the first decorative member 90 and the second decorative member 95. For example, it is assumed that the intervals A and B are smaller than the intervals A1 and B1 shown in FIG. 6 (see FIG. 9). In this case, the first contact portion 28 is bent at the first deformable portion 32, and the second contact portion 30 is bent at the second deformable portion 34 (see FIG. 9). That is, the first contact portion 28 can be deformed by the first deforming portion 32 into a form (shape) corresponding to the interval A2. The second contact portion 30 can be deformed by the second deforming portion 34 into a form (shape) corresponding to the interval B2. Variations in the size of the storage space S can be appropriately handled. The request | requirement of the dimensional accuracy with respect to the 1st decorative member 90 and the 2nd decorative member 95 can be suppressed.

<Modification>
The embodiment can also be performed as follows. Some configurations of the modifications shown below can be appropriately combined and employed. Hereinafter, points different from the above will be described, and description of similar points will be omitted as appropriate.

  (1) In the support member 20, the first deformation portion 32 is a groove along the height direction provided in the first contact portion 28, and the second deformation portion 34 is provided in the second contact portion 30. The grooves are along the height direction (see FIG. 4). The 1st deformation | transformation part should just be a shape which can deform | transform a 1st contact part into the form according to the space | interval A (refer FIG. 2) of the 2nd wall surface 81 and the 1st end surface 92. FIG. The 2nd deformation part should just be a shape which can change the 2nd contact part to the form according to space B (refer to Drawing 2) of the 1st wall surface 80 and the 2nd end face 97. For example, the first deformable portion and the second deformable portion may be a tubular deformable portion 38 as shown in FIG. FIG. 10 is an explanatory diagram illustrating the states of deformation of the first contact portion by the cylindrical first deformation portion and the second contact portion by the cylindrical second deformation portion. The contact part 36 and the deformation part 38 shown in FIG. 10 correspond to any combination of the first contact part and the first deformation part and the second contact part and the second deformation part.

  For example, it is assumed that the intervals A and B are smaller than the intervals A1 and B1 (see FIG. 6). When the intervals A and B are the intervals A1 and B1, it is assumed that the deforming portion 38 is in the state shown in the upper part of FIG. When the distances A and B are the distances A2 and B2, the deformed portion 38 is further crushed in the next direction as shown in the lower part of FIG. 10 as compared with the state shown in the upper part of FIG. The deformation part 38 deforms the contact part 36 in this way. When the contact portion 36 is the first contact portion and the deformation portion 38 is the first deformation portion, the aforementioned direction is a direction along the first wall surface 80. When the contact portion 36 is the second contact portion and the deformation portion 38 is the second deformation portion, the above-described direction is a direction along the second wall surface 81. In the support member, similar to each combination of the first contact portion 28 and the first deformable portion 32 and the second contact portion 30 and the second deformable portion 34 (see FIGS. 6 and 9), the deformable portion 38 causes the contact portion 36. The tip may be movable within a predetermined angle range with the deformable portion 38 as a base point.

  In the support member 20, the 1st deformation | transformation part 32 is provided in the 1st contact part 28, and the 2nd deformation | transformation part 34 is provided in the 2nd contact part 30 (refer FIG. 4). The first deformation part and the second deformation part may be provided at positions different from the above-described positions. For example, the first deformable portion may be provided between the base portion and the first contact portion. The base and the first contact portion are connected via the first deformation portion. For example, the second deformable portion may be provided between the base portion and the second contact portion. The base and the second contact portion are connected via the second deformation portion. In the support member, similarly to the combination of the first contact portion 28 and the first deformable portion 32 (see FIGS. 6 and 9), the first contact portion is determined by the first deformable portion and the tip is predetermined with the first deformable portion as a base point. It becomes possible to move the angle range. The first deforming portion deforms the first contact portion into a form corresponding to the interval A between the second wall surface 81 and the first end surface 92 by allowing the tip of the first contact portion to move within a predetermined angular range. . Further, in the support member, similarly to the combination of the second contact portion 30 and the second deformable portion 34 (see FIGS. 6 and 9), the second contact portion is the second deformable portion, and the tip is based on the second deformable portion. As a result, a predetermined angle range can be moved. A 2nd deformation | transformation part deform | transforms a 2nd contact part into the form according to the space | interval B of the 1st wall surface 80 and the 2nd end surface 97 by making the front-end | tip of a 2nd contact part movable within a predetermined angle range. .

  (2) In the covering member 40, the first surface 48 of the edge portion 47 in the third covering portion 46 is an inclined surface inclined toward the end in the height direction toward each side of the first wall surface 80 and the second wall surface 81. (See FIGS. 7 and 8). In the third covering portion, the first surface of the edge portion may have a shape different from the inclined surface. For example, the first surface of the edge may have a shape shown in the upper part of FIG. In the upper part of FIG. 11, in order to clarify the correspondence with the embodiment based on FIGS. 1 to 9, the reference numerals for the respective parts are the same as those described above. In the covering member 40 of the corner member 10 shown in the upper part of FIG. 11, the first surface 48 of the edge portion 47 in the third covering portion 46 is a horizontal plane perpendicular to the first wall surface 80 and the second wall surface 81. In this case, the first surface 48 is parallel to the second surface 49.

  When the corner member 10 shown in the upper part of FIG. 11 is installed in the corner 82 as the corner together with the first decorative member 90 and the second decorative member 95, the third covering is provided between the next side surface and the third covering portion 46. A step T corresponding to the thickness H of the portion 46 occurs at the next boundary position. The above-described side surfaces are the side surfaces that are the center sides of the first decorative member 90 and the second decorative member 95 in the height direction. The aforementioned boundary position is a position that is not covered by the third covering portion 46 among the aforementioned side surfaces. For example, in a building, wallpaper may be applied to the first wall surface 80 and the second wall surface 81. According to the corner member 10 shown in FIGS. 1 to 9, the step T unlike the case where the corner member 10 shown in the upper part of FIG. 11 is installed does not occur (see the lower part of FIG. 11). Therefore, the construction of the wallpaper at the construction site can be performed smoothly. For example, the wallpaper pasted on the first wall surface 80 can be linearly cut along the first decorative member 90 and the corner member 10. The wallpaper pasted on the second wall surface 81 can be linearly cut along the second decorative member 95 and the corner member 10. In the corner member 10 shown in the upper part of FIG. 11, when cutting the wallpaper, for example, it is assumed that an additional operation of removing the corner member 10 from the entering corner 82 is required. Further, the first decorative member 90 and the second decorative member 95 are not provided in the following areas. Each of the above-described regions is a region of the first wall surface 80 corresponding to the accommodation space S (refer to a region of “Interval A” in FIG. 2) and a region of the second wall surface 81 (refer to a region of “Interval B” in FIG. 2). is there. Each of the above-described regions forms a storage space S together with the first end surface 92 and the second end surface 97. Therefore, in the corner member 10 shown in the upper part of FIG. 11, when the wallpaper is linearly cut along either the first decorative member 90 or the second decorative member 95 in each of the above-described regions, the following tools are separately provided. It is also assumed that it must be used. The above-mentioned tool is a tool for assisting linear cutting of the wallpaper in each of the above-described regions. In the corner member 10 shown in FIGS. 1 to 9, such an additional work need not be performed, and further, the above-described tool is unnecessary. The corner member 10 shown in the upper part of FIG. 11 may be employed, for example, when wallpaper is not pasted on the first wall surface 80 and the second wall surface 81.

  Based on the above points, the following corner members can also be specified from the embodiment described above with reference to FIGS. This point will be described. In this description, in order to distinguish from the corner member 10 shown in FIGS. 1 to 9, the newly specified corner member is referred to as a “second corner member 10”. The reference numerals for the respective parts of the second corner member 10 that are the same as or correspond to the respective parts of the corner member 10 shown in FIGS.

  For example, the second corner member 10 is installed together with a decorative member at a corner 82 formed by a first wall surface 80 and a second wall surface 81 in a building provided with a decorative member that is either a baseboard or a peripheral edge. It is a corner member. The second corner member 10 includes a covering member 40. The covering member 40 is the second wall surface 81 side of the first decorative member 90 as the decorative member provided on the first wall surface 80 in the installed state in which the second corner member 10 is installed in the entrance corner 82. One end portion 91, a second end portion 96 on the first wall surface 80 side of the second decorative member 95 as a decorative member provided on the second wall surface 81, and the first end portion corresponding to the corner 82. 91 and the angular space adjacent to the second end 96 are covered. The aforementioned angular space is the accommodation space S (see FIG. 2). As described above, the housing space S includes the first end surface 92 of the first end portion 91 of the first decorative member 90 provided on the first wall surface 80 and the second end of the second decorative member 95 provided on the second wall surface 81. It can be said that the space is surrounded by the second end surface 97 of the two end portions 96 and the first wall surface 80 and the second wall surface 81 corresponding to the corner 82.

  The covering member 40 includes a first covering portion 42, a second covering portion 44, and a third covering portion 46. The first covering portion 42 covers the first end portion 91 and the corner space (accommodating space S) from the surface side opposite to the back surface that is the first wall surface 80 side of the first decorative member 90. The second covering portion 44 covers the second end portion 96 and the corner space (accommodating space S) from the surface side opposite to the back surface that is the second wall surface 81 side of the second decorative member 95. The third covering portion 46 covers the first end portion 91, the angular space (accommodating space S), and the second end portion 96 from the center side in the height direction of the first wall surface 80 and the second wall surface 81. In the covering member 40, the first covering portion 42, the second covering portion 44, and the third covering portion 46 are integrated. In the 3rd coating | coated part 46, the surface (1st surface 48) of the center side of the height direction of the edge part 47 of each side of the 1st wall surface 80 and the 2nd wall surface 81 along the 1st wall surface 80 and the 2nd wall surface 81 is provided. Is an inclined surface that is inclined toward an end side opposite to the center side in the height direction toward each side of the first wall surface 80 and the second wall surface 81.

  The second corner member 10 may be installed in the entrance corner 82 by the same method as that of a known corner member. In this case, the support member 20 may be omitted. When the support member 20 is omitted in the second corner member 10, the covering member 40 may substantially become the second corner member 10. The second corner member 10 may include a known configuration for installation in the entrance corner 82. The second corner member 10 can also be applied to a corner member for a protruding corner that is used when the corner portion of the first wall surface 80 and the second wall surface 81 is a protruding corner 83 (see FIG. 12). In FIG. 12, in order to clarify the correspondence with the embodiment based on FIGS. 1 to 9 and the lower part of FIG. In the corner member 10 for the projected corner shown in FIG. 12, the covering member 40 is the second of the first decorative member 90 provided on the first wall surface 80 in the installed state in which the corner member 10 is installed at the projected corner 83.

And the corner space adjacent to the first end portion 91 and the second end portion 96 and corresponding to the protruding corner 83. In FIG. 13, a region R2 indicated by a two-dot chain line is an illustration for convenience corresponding to the aforementioned angular space. The region R2 corresponds to a shape obtained by planarly viewing the aforementioned angular space. In FIG. 13, the arrows in the four thin lines indicating the correspondence between the region R2 and the angular space indicate the viewing direction. That is, the structure which makes the 1st surface 48 of the edge 47 in the 3rd coating | coated part 46 incline is variously installed in corner | angular parts, such as the entrance corner 82 or the exit corner 83 where the 1st wall surface 80 and the 2nd wall surface 81 meet. It can be employed as a corner member.

  (3) The support member 20 is provided with a first contact portion 28 and a second contact portion 30 (see FIG. 4). The support member 20 is accommodated in the accommodation space S (see FIG. 2). The first contact portion 28 contacts the first end surface 92, and the second contact portion 30 contacts the second end surface 97 (see FIGS. 6 and 9). Accordingly, the support member 20 is fixed to the entrance corner 82 while being accommodated in the accommodation space S. In the support member, the first contact portion 28 and the second contact portion 30 may be omitted. In this case, the first deformation part 32 and the second deformation part 34 are also omitted. When the first contact portion 28 and the second contact portion 30 are omitted from the support member, the support member may be fixed by, for example, one or both of an adhesive and an adhesive tape. Either one or both of an adhesive and an adhesive tape may be used in combination for fixing the support member 20 including the first contact portion 28 and the second contact portion 30.

  The first contact portion 28 has a shape protruding from the base portion 22 toward the first end surface 92, and the second contact portion 30 has a shape protruding from the base portion 22 toward the second end surface 97 (see FIG. 2 and FIG. 2). (See FIG. 4). The first contact portion may be provided on the first end surface 92 side and may be configured to be in contact with the first end surface 92. The 2nd contact part should just be the structure provided in the 2nd end surface 97 side and the 2nd end surface 97. For example, the support member may be configured such that the base is a cylinder, the first end surface 92 is in contact with the outer peripheral surface of the base of the cylinder, and the second end surface 97 is in contact with the outer peripheral surface of the base of the column. In this case, the first contact portion is provided on the first end surface 92 side of the outer peripheral surface of the base portion, and is formed by a region in contact with the first end surface 92. The second contact portion is provided on the second end surface 97 side of the outer peripheral surface of the base portion, and is formed by a region in contact with the second end surface 97.

  (4) The support member 20 is integrally formed by resin molding. In the support member 20, the first contact portion 28 and the second contact portion 30 are provided on the base portion 22 (see FIG. 4). For example, the support member may be formed as follows. That is, the first contact portion and the second contact portion are formed separately from the base portion. Thereafter, the first contact portion and the second contact portion are attached to the base portion. Along with this, an integral support member is formed. In this case, the base, the first contact portion, and the second contact portion may be made of different materials. For example, the first contact portion and the second contact portion may be a highly elastic material having higher elasticity than the base portion. Examples of the above highly elastic material include rubber or elastomer. In this case, in the support member, the first deformation portion and the second deformation portion may be omitted. The first contact portion and the second contact portion themselves are deformed.

  (5) In the corner member 10, the first engaging portion 24 is a fitting hole, and the second engaging portion 50 is fitted into the fitting hole as the first engaging portion 24 (see FIG. 8).
