Description

  The present invention relates to a corner piece for concealing a gap in a rotating edge cover.

  In many cases, a turning edge is provided between the wall and the ceiling of a building such as a house. The turning edge is a member attached to the boundary between the wall and the ceiling, and has a role of connecting the wall panel and the ceiling panel. A turning edge cover, which is a decorative member, is attached to the turning edge, and it has a role to alleviate a sense of incongruity caused by the difference in color and material between the wall and the ceiling, and to hide the gap between the seams.

  In recent unit baths, the wall and ceiling are panels, which are connected to form a room (no columns or beams are used). Patent Document 1 describes a configuration in which a wall panel and a ceiling panel are connected by a piece member (turning edge), and a joint member (turning edge cover) is attached to the front surface of the piece member as a makeup. In Patent Document 1, it is described that the joint member is provided with fins with respect to the wall panel and the ceiling panel and abuts in a watertight and airtight manner. That is, the turning edge cover (joint member) has a role of makeup that hides the turning edge, which is a structure, and a watertight and airtight role for the turning edge.

  By the way, the ceiling panel is first installed after turning around the edge of the ceiling panel and then dropping the edge into the upper end of the wall panel from above. At this time, if it is going to be attached to the wall panel in a state where the edge is attached to the corner of the ceiling panel, the dimensional accuracy of the wall panel and the ceiling panel is required to be very high. For this reason, it is necessary for the turning edge to have a dimension that does not reach the corner of the ceiling panel. Then, since there is no turning edge in the corner, it is difficult to attach the outer covering material of the turning edge cover. Therefore, conventionally, the sealing material is generally filled in the clearance of the turning edge cover.

  However, the portion treated with the sealing material tends to accumulate dirt in a long-term use state, and in particular, tends to be a source of mold.

  Further, since the end portion of the turning edge cover can be visually recognized when the sealing material is filled, the dislocation of the both ends of the turning edge cover is easily noticeable. Therefore, it is necessary to turn and attach the edge cover so that the left and right gaps are even. However, it requires careful work and repeats temporary fixing and position adjustment.

  Furthermore, when using a sealing material, it is necessary to mask (curing) so that it does not adhere to the surroundings, or to wait for the sealing material to harden to some extent before wiping off the excess. Also in this point, there is a problem that it takes time for construction.

  Conventionally, there is a configuration in which the gaps at the corners are hidden by a member rather than a sealing material. Patent Document 2 proposes a structure in which a corner piece is fixed to a corner portion where a wall intersects, and is attached to a corner side edge of an edge cover by swiveling around the back side of the surface portion of the corner piece. . According to Patent Document 2, it is possible to provide a ceiling rim cover mounting structure that has good workability and can absorb construction errors by the above configuration.

  Further, Patent Document 3 discloses a structure in which a wall fixing member is nailed and fixed to a wall of a corner (corner), and a corner covering member covering a gap of the baseboard is fitted to a slit of the wall fixing member. Has been proposed. In Patent Document 3, it is assumed that the corner covering tool can be easily attached without processing the skirting board and the turning edge cover by the above-described configuration and is not adversely affected by the expansion and contraction of the skirting board.

  In the configuration of Patent Document 2, the edge cover is attached with the corner piece and the guide rail fixed in advance in a corner portion. At this time, the length of the turning edge cover is necessarily longer than the distance between the corner pieces on both sides. For this reason, Patent Document 2 describes that after one end of the turning edge cover is inserted into the corner piece, the other end is inserted into the opposite corner piece while slightly bending the turning edge cover. However, it is difficult to insert the tip of the long rotating edge cover while being bent in the air, and it is difficult to say that the workability is good. Further, since it is necessary to fix the corner piece, there is a problem that the construction time and cost increase because the number of parts and the number of man-hours increase.

  Moreover, in the structure of patent document 3, in order to fix a corner covering tool, the wall fixing member used as a receiver is needed. For this reason, there is still a problem that the number of parts and man-hours are increased, and the construction time and cost are increased.

  Therefore, the present invention provides a corner piece that can hide the gap of the turning edge cover without filling it with sealing, can be easily and quickly attached by hand, and has a sufficient holding force after attachment. The purpose is that.

  In order to solve the above problems, a typical configuration of a corner piece according to the present invention is generated when a hollow turning edge cover attached to a turning edge connecting a wall panel and a ceiling panel is attached to a corner of the ceiling. A corner piece that hides the gap, covers the gap between the front edge of the edge cover on both sides and covers the gap. The core part and the left and right sides of the core part are erected in the shape of a wing that is inclined forward, and is flexible and can be inserted into the gap of the turning edge cover. It is characterized by having a fin portion that is locked to the inner surface.

  According to the above configuration, since the corner piece can be attached by simply inserting the turning edge cover into the gap, the gap can be hidden without filling the gap of the turning edge cover with the sealing material. It can be easily and quickly installed by work. In addition, a sufficient holding force can be obtained when the fin portion rotates and spreads inside the edge cover.

  The fin portion preferably has a high step portion having a width corresponding to the height of the inner space of the turning edge cover and a low step portion provided at a position corresponding to the end face of the turning edge cover. As a result, the high step portion regulates the vertical movement inside the turning edge cover, and the low step portion is always pressed against the end face of the turning edge cover to prevent displacement, thereby further improving the holding force and stability. be able to.

  It is preferable that a plurality of fin portions are provided in parallel in the insertion direction, and a protrusion that thickens a portion that contacts the inner surface of the turning edge cover is provided at the lower end of the innermost fin portion. Thereby, while ensuring the flexibility of the fin portion, it is possible to prevent the portion in contact with the inner surface of the turning edge cover from buckling, and to further improve the holding force and stability.

  It is preferable that a plurality of fin portions are provided in parallel in the insertion direction, and the innermost fin portion is thicker than the other fin portions. Thereby, the intensity | strength at the time of inserting a corner piece in a narrow clearance gap can be acquired. Further, the buckling of the fin portion due to the rotational moment can be effectively prevented.

  According to the present invention, it is possible to hide the gap of the turning edge cover without filling it with sealing, and it is possible to easily and quickly mount the corner piece by hand, and to provide a corner piece having a sufficient holding force after mounting. can do.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  The corner piece concerning this invention hides the clearance gap between the turning edge covers arrange | positioned along with the corner | corner of the ceiling. Here, the corner piece according to the present invention is characterized in that it can be manually attached to the gap of the previously installed turning edge cover and is locked using the inner surface of the hollow turning edge cover. .

  1A and 1B are diagrams for explaining how the corner piece is used. FIG. 1A is a diagram for explaining the assembly of the ceiling panel 110 and the wall panel 120, and FIG. FIG. 1 and FIG. 1C are diagrams showing the corner piece 200 after being mounted. In FIG. 1A and FIG. 1B, the ceiling panel 110 is drawn and displayed transparently by a two-dot chain line.

  Fig.1 (a) has shown the corner | angular part of the ceiling of a bathroom. The bathroom is configured by connecting a ceiling panel 110 and a wall panel 120. The ceiling panel 110 and the wall panel 120 are connected by a turning edge 130, and a turning edge cover 140 is attached to the interior side of the turning edge 130.

  The turning edge 130 serves to connect the ceiling panel 110 and the wall panel 120. The turning edge 130 is a long member (extruded product) formed of a hard elastic material (for example, aluminum or hard resin).

  The turning edge 130 forms a pocket by the upper folded portion 132 that goes around the upper surface of the end portion of the ceiling panel 110 and the boundary portion 134 that is located between the ceiling panel 110 and the wall panel 120, and bites the edge of the ceiling panel 110. Fixed.

  Continuing from the boundary portion 134, the front wall portion 136 hangs down on the front side (inside the room) of the wall panel 120, and the rear folded portion 137 hangs down on the back side (outside of the wall) of the wall panel 120. A pocket is formed by the boundary portion 134, the front wall portion 136, and the rear turn-back portion 137, and the ceiling panel 110 and the wall panel 120 are connected by dropping this into the upper end portion of the wall panel 120. In this state, the joint between the ceiling panel 110 and the wall panel 120 at the corner of the ceiling is sealed with a sealing material.

  Note that the upper folded portion 132 and the rear folded portion 137 are bent in a bowl shape to enhance the spring property even if it is a hard material.

  The turning edge cover 140 serves to hide the boundary between the ceiling panel 110 and the wall panel 120. The rotating edge cover 140 is a long member (extruded product) formed from a hard material (for example, aluminum or hard resin). The turning edge cover 140 does not use elasticity, but may be made of the same material as the turning edge 130.

  The rotating edge cover 140 includes a cover front surface portion 142 and a cover lower surface portion 144 which are decorative surfaces. An upper fin 142 a that has flexibility and is in close contact with the ceiling panel 110 is provided at the upper end of the cover front surface portion 142. A lower fin 144 a that is in close contact with the wall panel 120 is provided at the lower end of the cover lower surface portion 144. The upper fin 142a and the lower fin 144a are made of a soft resin material that is more flexible than the base body (the cover front surface portion 142 and the cover lower surface portion 144) of the rotating edge cover 140, and are formed integrally with the base body by two-color molding. .

  A rib 146 for fixing to the turning edge 130 is provided on the inner surface of the cover front surface portion 142. On the other hand, a clip portion 138 for inserting and fixing the turning edge cover 140 is provided on the front wall portion 136 of the turning edge 130. Therefore, the turning edge cover 140 can be attached and fixed simply by pushing the rib 146 into the clip portion 138.

  Thus, the turning edge cover 140 is hollow, and when the turning edge cover 140 is attached to the turning edge 130, an internal space 150 is formed inside thereof. At the corner, the end of the turning edge cover 140 is cut at 45 degrees.

  When the ceiling panel 110 and the wall panel 120 are connected as described above and the turning edge cover 140 is attached, a gap is formed at the corner of the turning edge cover 140 as shown in FIG. Therefore, when the corner piece 200 described below is inserted into the gap and attached, the gap can be closed as shown in FIG.

  2A and 2B are perspective views of the corner piece 200, in which FIG. 2A is a front perspective view and FIG. 2B is a rear perspective view. FIG. 3 is a five-side view of the corner piece 200. Hereinafter, the corner piece 200 will be described with reference to FIGS. 2 and 3.

  The corner piece 200 includes a front surface portion 210, a plate-shaped core portion 220, and a plurality of fin portions 230, 232, and 234. The corner piece is made of a soft resin material, and the front surface portion 210 and the fin portions 230, 232, and 234 need to be flexible.

  The front portion 210 has a role of covering the gap between the turning edge covers 140 on both sides. The front surface part 210 has a bent shape so as to follow the cover front surface part 142 and the cover lower surface part 144. The width of the front face 210 is wider than the gap (actually, the length of the turning edge cover 140 is adjusted so that the gap of the turning edge cover 140 is narrower than the width of the front face 210). Thereby, the front surface part 210 can cover the gap by covering the front surface side of the end part of the turning edge cover 140 on both sides when being mounted.

  An upper tab 212 that is in close contact with the ceiling panel 110 is provided at the upper end of the front surface portion 210. In addition, a lower tab 214 that is in close contact with the corners of the left and right wall panels 120 is provided at the lower end of the front portion 210.

  The front surface portion 210 and the lower tab 214 abut against surfaces that are orthogonal to each other. Therefore, the front surface portion 210 and the lower tab 214 have an R-shaped cross section so that the center in the width direction is recessed. Thereby, the surfaces of the turning edge covers 140 on both sides can be made visually smooth.

  The upper tab 212 abuts on the flat ceiling panel 110. The upper tab 212 is a substantially flat portion, but an R-shaped notch 212 a is formed at the tip of the upper tab 212. Thereby, the upper tab 212 can contact the ceiling panel 110 without a gap.

  The core portion 220 is erected in the center of the back surface of the front surface portion 210 and serves as a core material when inserted into the gap of the turning edge cover 140. The core portion 220 is preferably high in rigidity (is less likely to bend), and is thicker than the front surface portion 210 and the fin portions 230, 232, and 234.

  The fin portions 230, 232, and 234 are erected on the left and right sides of the core portion 220 in a blade shape that is inclined forward (inside the room) (in a state where the fin portions are tilted backward with respect to the insertion direction). Each of the fin portions 230, 232, and 234 is a thin plate, and a plurality of fin portions are provided in parallel in the insertion direction. The fin portion is flexible, and its width (distance from the tip of the fin portion on one surface of the core portion 220 to the tip of the fin portion on the other surface) is the clearance of the turning edge cover 140. It is getting wider.

  4A and 4B are diagrams for explaining the state of the fin portion when the corner piece 200 is rotated and inserted into the gap of the edge cover 140. FIG. 4A shows a state in the middle of insertion, and FIG. ing. As shown in FIG. 4A, the fin portions 230, 232, and 234 are bent so as to be sequentially folded by the cover front surface portion 142 as the corner piece 200 is inserted into the gap. Thereby, the corner piece 200 can be turned and inserted into the gap of the edge cover 140. Further, when the fin portions 230, 232, and 234 are turned and enter the inner space 150 of the edge cover 140, the bent portions spread and do not fall off.

  Finally, as shown in FIG. 4B, the fin portion 234 located on the foremost side turns and contacts the inner surface of the edge cover 140 and is locked. In the final stage of insertion, the front surface portion 210 is bent by being pushed slightly excessively, and the tip of the last fin portion 234 is fed into the internal space 150. Therefore, the cover front surface portion 142 is sandwiched between the fin portion 234 and the front surface portion 210, and a high holding force, stability (not wobbling), and adhesion (no gap is generated) can be obtained.

  In this embodiment, the corner piece 200 is provided with three fin portions 230, 232, and 234. The innermost fin portion 230 has a role to slightly bend the turning edge cover 140 on both sides when being pushed into the clearance of the turning edge cover 140, and a vertical posture by contacting the inner surface of the turning edge cover 140 when insertion is completed. It has the role of maintaining (the posture in the rotational direction). The front fin portion 234 has a role of locking to the inner surface of the cover front surface portion 142 to prevent the insertion direction (horizontal direction) from falling off. The fin part 232 between them has a role of continuing the bending of the back fin part 230 to the fin part 234 on the near side. If the fin portion 232 is not provided, the open fin portion 234 hits the cover front surface portion 142, which makes it difficult to insert.

  In the present embodiment, three fin portions are provided. However, if the back side and the near side fin portions are close to each other, two fin portions may be provided without providing any intermediate fin portions. Further, if the back side and the front side fin portions are far from each other, the number of fin portions between them may be increased to form a configuration of four or five pieces.

  As described above, in the corner piece according to the present invention, the corner piece 200 can be attached simply by inserting it into the gap after attaching the turning edge cover 140. Therefore, the gap can be hidden without filling the gap of the turning edge cover 140 with sealing. The sealing material used for the joint between the ceiling panel 110 and the wall panel 120 is hidden by the turning edge cover 140 and the corner piece 200 and is not observed from the appearance. Moreover, since the work at the time of attachment can be performed manually without using tools or tools, it can be performed easily and quickly, and the construction time can be greatly shortened. Moreover, since it is not necessary to fix the receiving member for attaching a corner piece, the number of parts, construction time, and cost do not increase. Further, when the fin portion is rotated and spreads inside the edge cover 140, the falling is prevented by locking, not by friction, so that a sufficient holding force can be obtained.

  The reason for providing the plurality of fins is to further improve the holding force and stability. If only the return in the direction opposite to the insertion direction is prevented, only the fin portion 234 in the vicinity of the front surface portion 210 is required. However, when the plurality of fin portions 230, 232, and 234 are in contact with the inner surface of the internal space 150, the vertical displacement and the rotational displacement of the corner piece 200 can be reliably prevented.

  5A and 5B are diagrams for explaining the details of the fin portion. FIG. 5A is a diagram for explaining the high step portion and the low step portion, and FIG. 5B is a diagram for explaining the protrusion.

  As shown in FIG. 5A, the fin portion 230 includes a high step portion 230a having a width w1 corresponding to the height h1 of the internal space 150 of the turning edge cover 140, and an end face of the turning edge cover 140 (an end face of the rib 146). ), And a low step portion 230b provided at a position corresponding to. The high step portion 230a preferably has a dimensional relationship that can be accommodated in the internal space 150 without wobble, and w1 ≦ h1. Further, although not indicated in the figure, the other fin portions 232 and 234 have the same structure.

  Accordingly, the high step portion 230a restricts the movement in the vertical direction inside the turning edge cover 140. The low step portion 230b is always in pressure contact with the end surface of the rib 146 of the turning edge cover 140 to generate friction and prevent displacement. In addition, since the core part 220 is centered with respect to the gap of the edge cover 140 by the low step part 230b abutting on both sides, the corner piece 200 is not offset and the high step part 230a is rotated. Can be prevented from coming off. Thus, by providing not only the high step portion 230a that enters the internal space 150 but also the low step portion 230b that comes into contact with the end surface of the turning edge cover 140, the holding force and stability can be further improved.

  Further, as shown in FIGS. 5B and 2B, a protrusion 230c is provided at the lower end of the innermost fin portion 230 to thicken the portion that contacts the inner surface of the turning edge cover 140. Yes. In this way, by partially thickening, while ensuring the flexibility of the fin portion 230, it is possible to prevent the portion contacting the inner surface of the turning edge cover 140 from buckling, Stability can be improved.

  As shown in FIGS. 2B and 3, the innermost fin portion 230 is formed thicker than the other fin portions 232 and 234. Thereby, the intensity | strength at the time of inserting the corner piece 200 in a narrow clearance gap can be acquired. For example, if the innermost fin portion 230 is also thinned, the core portion 220 will buckle and enter when the corner piece 200 is pushed in when the gap of the turning edge cover 140 and the width of the core portion 220 are about the same. Absent. Therefore, by increasing the thickness of the fin portion 230 and increasing the strength of the tip portion, the turning edge covers 140 on both sides can be slightly bent and inserted.

  In the state where the corner piece 200 is mounted, the upper tab 212 of the front face 210 is brought into contact with the ceiling panel 110 and the lower tab 214 is brought into contact with the wall panel 120, so that a force in the rotational direction is applied to the corner piece 200. Due to this rotational moment, the largest vertical force is applied to the innermost fin portion 230 among the plurality of fin portions. Therefore, not only the protrusion 230c but also the entire innermost fin portion 230 is made thick so that buckling due to a rotational moment can be effectively prevented.

  Further, the protrusion 230c is provided in order to obtain a certain degree of vertical strength. However, if the innermost fin portion 230 is thinned, the protrusion amount of the protrusion 230c must be increased accordingly. Then, when inserting, it becomes difficult to insert the protrusion 230c by holding the edge cover 140 on both sides. That is, increasing the thickness of the fin portion 230 also has a role of suppressing the protrusion amount of the protrusion 230c.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used as a corner piece for concealing the gap of the turning edge cover.
