  Here, in the above prior art and the like, as illustrated in FIG. 9, an article b to be protected by the square contact member a includes a vertical surface c and a horizontal surface d that are orthogonal to each other, and the vertical surface c and the horizontal surface. The square contact member a has a vertical wall portion f, a horizontal wall portion g, and a pair of surfaces that are in contact with the surfaces c, d, e, and e of the article b. The wall portions f, g, h, and h define a corner portion receiving space x for receiving the corner portion of the article b, and these wall portions f. , G, h, h, each open side i, j, k, k forms an article entrance y of the accommodation space x.

  When the corner contact member a is attached to the corner of the article b, the corner portion of the article b is moved into the above-described entrance by moving the corner contact member a obliquely relative to the article b as indicated by an arrow A. In this case, the side wall portion is in contact with the front surface and the back surface e, e of the article b among the open side portions i, j, k, k. The open sides k and k of h and h move on the both surfaces e and e while rubbing the front and back surfaces e and e of the article b continuously.

  However, at this time, conventionally, the edge portions m and m on the inner surface side of the open side portions k and k are not chamfered and are left in an angular state. The front and back surfaces e and e of b may be rubbed and scratched by the edge portions m and m on the inner surface side of the open sides k and k.

  In particular, when the article b has a structure in which a decorative material p such as an olefin sheet or reinforced paper is laminated on the core material n, the front and back surfaces e and e of the article b are damaged and the decorative material p If it is torn or peeled off, the background of the core material n is exposed and the commercial value of the article b is impaired.

  In addition, as illustrated in FIG. 9, when a small edge surface (lateral surface d in the illustrated example) to which the decorative material p is not applied is left at the corner portion of the article b, particularly from the surface d. The end of the decorative material p is caught by the open sides k, k of the square contact member a, so that the decorative material p is easily peeled off as indicated by reference sign z.

  Then, this invention makes it a subject to prevent the surface and back surface of an article | item from being damaged by the open side part of the side wall part of this square contact member, when mounting | wearing the corner | angular part of an article | item. Hereinafter, the present invention will be described in detail including other problems.

  That is, the invention according to claim 1 of the present application is a corner contact member attached to a corner portion where the facet surfaces of the panel material are orthogonal to each other, and the first and second parts are respectively orthogonal to each other and contact the both facet surfaces. A pair of parallel side wall portions that are provided in a substantially triangular shape between the two fore edge receiving wall portions and the side end portions that are orthogonal to each other on both sides of the fore edge receiving wall portions, and respectively contact the front and back surfaces of the panel material corner portion. And each of the wall portions forms a corner portion accommodating space for accommodating a corner portion of the panel material, and is provided on the inner surface side of the open side portion that is not continuous with the edge receiving wall portion of the both side wall portions. The edge part is formed in a curved surface shape or an obtuse angle shape in a cross section.

  Next, the invention according to claim 2 is characterized in that, in the square contact member according to claim 1, the substantially triangular side wall portion has a shape in which the open side portion bulges outward. And

  Next, the invention described in claim 3 is characterized in that, in the square contact member described in claim 2, the open side portion bulges outward in a rounded shape.

  Next, the invention according to claim 4 is the square contact member according to any one of claims 1 to 3, wherein at least one side wall portion has a base portion on the open side portion side, and the tip portion is A cut-and-raised piece that slightly enters into the corner housing space is provided, and the edge part on the inner surface side of the tip of the cut-and-raised piece is formed in a curved surface or an obtuse angle in the cross section. Features.

  According to a fifth aspect of the present invention, in the square contact member according to any one of the first to fourth aspects, all the constituent elements are integrally formed of resin.

  According to the first aspect of the present invention, the front and back surfaces of the panel member are continuously connected when the cornering member is attached to the corner of the panel member to be protected (for example, a fitting such as an interior door or a hanging door). Since the edge portion on the inner surface side of the open side portion of the side wall portion of the square contact member that is to be rubbed is formed into a curved surface or an obtuse angle shape in the cross section, a panel is formed at the open side portion. The problem that the front and back surfaces of the material are rubbed and damaged is suppressed. As a result, even if the panel material has a structure in which a decorative material such as an olefin sheet or reinforced paper is laminated on the core material, it is suppressed that the decorative material is torn or peeled off. Will not drop.

  Next, according to the second aspect of the present invention, the substantially triangular side wall portion of the square contact member has a panel material to be mounted as compared with the other first and second fore edge receiving wall portions. Therefore, when mounting this cornering member on the corner of the panel material, it is easy to mount it by first hooking the protruding portion of the side wall portion on the corner of the panel material. You can do it.

  Next, according to the invention described in claim 3, since the overhanging portion of the side wall portion has a rounded shape, even if the overhanging portion accidentally collides with the panel material, etc. The panel material is prevented from being damaged at the overhanging portion.

  Next, according to the invention described in claim 4, the cut and raised pieces provided on the side wall portion enter a small amount into the corner portion accommodating space to exhibit the function as the aforementioned pressing piece. When the square contact member is mounted on the panel material, the cut and raised piece prevents the square contact member from falling off the panel material to be protected by pressing at least one of the front or back surface of the panel material. .

  However, in this case, the edge portion on the inner surface side at the tip end portion of the cut and raised piece is the same as the edge portion on the inner surface side of the open side portion when the square contact member is attached to the corner portion of the panel material or the corner portion. When the abutting member is removed from the corner of the panel material, the front and back surfaces of the panel material are rubbed continuously, so that the edge portion on the inner surface side of the tip portion of the cut and raised piece is also chamfered. Otherwise, there is a possibility that the edge and the back of the panel material will be rubbed and damaged.

  Therefore, in the invention according to claim 4, when the corner contact member is attached to the corner portion of the panel material and removed from the corner portion of the panel material, the front and back surfaces of the panel material are continuously rubbed. The edge portion on the inner surface side of the leading end portion of the cut and raised piece is also formed into a curved surface or an obtuse angle in the cross section so as to be chamfered. As a result, the problem of rubbing and scratching the front and back surfaces of the panel material at the tip of the cut and raised piece as well as the open side portion of the side wall portion is suppressed, even if the panel material is olefin sheet or reinforced paper on the core material. Even if the decorative material is laminated, it is suppressed that the decorative material is torn or peeled off, and the commercial value of the panel material is secured.

  According to the fifth aspect of the invention, since all the components of the square contact member are integrally formed of resin, the square contact member is easily and easily manufactured, and as a result, the panel material to be protected Cost increase can be suppressed.

  Here, the resin that can be used for integral molding of the square contact member is not particularly limited. For example, polyethylene resin (PE), polyethylene terephthalate resin (PET), polypropylene resin (PP), and the like can be molded and plastically deformed. It is preferable in terms of safety or economy. Hereinafter, the present invention will be described in more detail through embodiments.

  In the present embodiment, the present invention is applied to the square contact member 1 shown in FIG. The square contact member 1 is located on both sides of the vertical wall portion (small edge receiving wall portion) 10 extending in the vertical direction, the horizontal wall portion (small edge receiving wall portion) 20 extending in the horizontal direction, and these two wall portions 10 and 20. And a pair of left and right side wall portions 30, 30 extending in the vertical direction, and a corner portion accommodating space X is defined by these four wall portions 10, 20, 30, 30, and these four wall portions An article entrance Y of the accommodation space X is formed by the open side portions 10a, 20a, 20a, 30a, and 30a of the 10, 20, 30, and 30.

  As shown in FIG. 2, the corner contact member 1 is attached to, for example, the corners of the four corners of the interior door 100 to be protected. In that case, the vertical wall portion (small edge receiving wall portion) 10 of the corner contact member 1 is in contact with the left and right small edge surfaces 101 among the surfaces orthogonal to each other at the corner portion of the interior door 100, and the horizontal wall portion (small edge receiving wall portion). ) 20 is in contact with the upper and lower fore edge surfaces 102, and the side wall portion 30 is in contact with the front surface or the back surface 103. And when this corner contact member 1 is attached to the corner of the interior door 100, the corner contact member 1 is moved obliquely relative to the interior door 100 as indicated by the arrow A, and the corner of the interior door 100 is moved. It is made to enter into the accommodation space X through the entrance Y. On the contrary, when the corner contact member 1 is removed from the corner portion of the interior door 100, the corner contact member 1 is relatively moved as indicated by the arrow B, and the corner portion of the interior door 100 is detached from the housing space X.

  Returning to FIG. 1, the vertical wall portion 10 is formed of a rectangular single wall, and the horizontal wall portion 20 is sandwiched between a single wall 21 having a narrower width than the single wall 21. The side wall portions 30 and 30 are formed of a single wall having a substantially triangular shape but having five sides.

  Here, the lower end portion of the vertical wall portion 10 and the rear end portion of the single wall 21 of the horizontal wall portion 20 intersect at 90 ° and are continuous. Further, the left and right end portions of the single wall 21 of the lateral wall portion 20 and the lower surfaces of the quadrangular prism elements 22 and 22 are continuous with each other. Further, the rear end portions of the quadrangular column elements 22, 22 of the horizontal wall portion 20 abut against the lower portion of the vertical wall portion 10 and are continuous. On the other hand, the rear end portions of the side wall portions 30 and 30 and the left and right end portions of the vertical wall portion 10 are continuous at 90 °. And the lower end part of the side wall parts 30 and 30 and the outer surface of the quadratic prism elements 22 and 22 of the horizontal wall part 20 are continuing on the same plane.

  Here, since the horizontal wall portion 20 includes not only the single wall 21 but also the quadrangular prism elements 22 and 22 having a hollow structure, an effective impact interference action is exhibited. Further, as shown in FIG. 3, the horizontal wall portion 20 is in contact with the upper and lower small facets 102 of the interior door 100 on the upper surfaces of the quadrangular prism elements 22 and 22. As a result, the upper end portion of the vertical wall portion 10 that is not continuous with the mutually adjacent wall portions becomes the open side portion 10a, and the front upper end portions of the square column elements 22 and 22 of the horizontal wall portion 20 are the open side portion 20a, 20a, and the upper end portion, the inclined end portion, and the front end portion of the five sides of the side wall portions 30 and 30 become the open side portions 30a and 30a as a whole. Mouth Y is formed.

  Therefore, when the corner contact member 1 is mounted on the corner of the interior door 100, the surface of the interior door 100 and the back surface 103, 103 of the open side portions 10 a, 20 a, 20 a, 30 a, and 30 a are brought into contact with each other. The open side portions 30a and 30a of the side wall portions 30 and 30 move on the surfaces 103 and 103 while continuously rubbing the front and back surfaces 103 and 103 of the interior door 100. Therefore, in this corner contact member 1, in order to suppress damage by rubbing or scraping the front surface and the back surface 103, 103 of the interior door 100 at the open side portions 30a, 30a of the side wall portions 30, 30. The edge portions 30b and 30b on the inner surface side of the open side portions 30a and 30a are chamfered.

  Specifically, as shown in an enlarged view in FIG. 4, the edge portions 30 b and 30 b on the inner surface side of the open side portions 30 a and 30 a of the side wall portions 30 and 30 of the square contact member 1 are curved (R-shaped) in cross section. ). Thus, when the corner contact member 1 is mounted, the open side portions 30a and 30a of the side wall portions 30 and 30 are placed in the mounting direction A on the front and back surfaces 103 and 103 of the interior door 100 that has entered the housing space X. As a result, even if the interior door 100 has a structure in which a decorative material 112 such as an olefin sheet or reinforced paper is laminated on a wooden core material 111, the decorative material 112 is torn. It is suppressed that the core material 111 is exposed, and the commercial value of the interior door 100 is guaranteed.

  Alternatively, as illustrated in FIG. 5, the edge portions 30 b and 30 b on the inner surface side of the open side portions 30 a and 30 a of the side wall portions 30 and 30 of the square contact member 1 are cut off, and the front and back surfaces 103, Even if the angles of the edge portions 30b and 30b with respect to the surface 103 are formed in an obtuse angle in the cross section, the same effect can be obtained.

  Furthermore, as illustrated in FIG. 6, not only the inner edge portions 30 b and 30 b of the open side portions 30 a and 30 a of the side walls 30 and 30, but also the outer surface side (the anti-accommodating space X side or the anti-interior door 100 side). The chamfering process may also be performed for the edge part.

  Further, as shown in FIG. 1, in the present embodiment, the substantially triangular sidewall 30 is a line (illustrated by a chain line) connecting the open side 10 a of the vertical wall 10 and the open side 20 a of the horizontal wall 20. ) Bulges outward in a side view (overhang portion 30c). Thereby, the side wall part 30 of the corner contact member 1 protrudes to the side of the interior door 100 to be mounted (the side in the mounting direction A) as compared to the other vertical wall part 10 and the horizontal wall part 20 or the like. Therefore, when the corner contact member 1 is attached to the corner portion of the interior door 100, the extension portion 30c is first hooked on the corner portion of the interior door 100 so that the attachment can be easily performed.

  In addition, the intersection 30d between the upper end portion and the inclined end portion in the overhang portion 30c and the intersection point 30d between the inclined end portion and the near end portion, that is, the protruding end of the overhang portion 30c are curved and rounded in a side view. Therefore, even if the overhanging portion 30c accidentally collides with the interior door 100 when the cornering member 1 is mounted, the interior door 100 may be damaged by the overhanging portion 30c. It is avoided.

  Here, the edge portion 30b on the inner surface side is not chamfered over the entire area of the open side portion 30a of the side wall portion 30, but depending on the situation, the edge portion on the inner surface side in only a part of the open side portion 30a. 30b may be chamfered. For example, in the present embodiment, among the open side portions 30 a of the side wall portion 30, the inclined end portion belonging to the overhang portion 30 c is the longest and extends perpendicularly to the mounting direction A, so that the surface of the interior door 100 Since the degree of rubbing the back surface 103 is the highest, the chamfering process is omitted on the inner edge side of the upper edge part and the front edge part of the open side part 30a, and only the edge part on the inner surface side of the inclined edge part is chamfered. It doesn't matter.

  Then, as shown in FIG. 1, a substantially U-shaped cut is made at the approximate center of the side wall portions 30, 30 of the square contact member 1, and the resulting pieces 40, 40 are raised up inside. As shown in FIG. 3, the tip portion projects slightly into the corner portion accommodating space X. Therefore, the cut-and-raised pieces 40 and 40 function as pressing pieces that press the front and back surfaces 103 and 103 of the interior door 100 that is inserted into the corner portion accommodating space X, and thereby the corner contact member 1 is disposed in the interior. When attached to the door 100, the cornering member 1 is prevented from falling off from the interior door 100 which is a protection target.

  In the present embodiment, as shown in an enlarged view in FIG. 7, the edge portion 40c on the inner surface side of the tip end portion 40b of the drop-off preventing cut-and-raised piece 40 is also formed in a curved surface or obtuse angle shape in cross section. ing. That is, as described above, the cut-and-raised piece 40 protrudes into the housing space X so as to press the front and back surfaces 103, 103 of the interior door 100 that has entered the housing space X with a predetermined elastic restoring force. Therefore, the edge portion 40c on the inner surface side of the tip end portion 40b is the same as the edge portion 30b on the inner surface side of the open side portion 30a of the side wall portion 30 when the square contact member 1 is attached to the interior door 100. When the cornering member 1 is removed from the interior door 100 (detachment direction B), the front and back surfaces 103 of the interior door 100 are rubbed continuously.

  Therefore, by chamfering the edge portion 40c on the inner surface side of the tip end portion 40b of the cut and raised piece 40, it is possible to prevent the edge portion 40c from damaging the front surface and the back surface 103, 103 of the interior door 100. I did it. In particular, since the cut and raised pieces 40 come into contact with the front and back surfaces 103 and 103 of the interior door 100 where the decorative material 112 is highly likely to be laminated and stuck on the core material 111, the damage to the surface 103 is suppressed. The effect is very great.

  As shown in FIG. 7, the rising base 40a of the cut and raised piece 40 is closer to the entrance Y than the tip 40b (that is, the open side 30a side). Therefore, when the corner contact member 1 is mounted, the article 100 relatively moves from the base portion 40a side toward the tip end portion 40b side, and as a result, the cut and raised pieces 40 are laid down in order. On the other hand, when the corner contact member 1 is removed, the article 100 relatively moves from the distal end portion 40b side to the base portion 40a side, and as a result, the cut and raised pieces 40 are raised up in the opposite direction. Therefore, it can be said that the edge portion 40c on the inner surface side of the tip end portion 40b of the cut and raised piece 40 has a higher possibility of rubbing and damaging the front surface and the back surface 103, 103 of the interior door 100 at the time of removal than at the time of mounting. .

  Moreover, as illustrated in FIGS. 1 and 3, the side wall portions 30, 30 of the square contact member 1 have V-shaped grooves 50 that run along the back end portion and the lower end portion of the side wall portions 30, 30. 50 is formed. The concave groove 50 is formed on at least one of the side walls when the width of the interior door 100 that enters the housing space X is unexpectedly excessive, or when an accessory projects from the front surface or the back surface 103 of the interior door 100. This is for cutting out and removing the portion 30 (the broken line shown in the enlarged circle in FIG. 3 is one specific example of the cutting line at that time).

  The square contact member 1 is made of, for example, polyethylene resin (PE), polyethylene terephthalate resin (PET), polypropylene resin (PP), or the like in consideration of moldability, plastic deformability, economy, and the like. All the components are integrally molded by injection molding. Thereby, manufacture of this corner contact member 1 becomes easy and easy, and also the cost reduction of the interior door 100 which is a protection object is also achieved.

  The embodiment described above is the best mode for carrying out the present invention, but it goes without saying that various modifications and omissions can be made without departing from the spirit of the present invention. For example, as illustrated in FIG. 8, the overhanging portion 30c, the cut-and-raised piece 40, the V-shaped groove 50, etc. in the side wall portion 30 are all omitted, or the lateral wall portion 20 is configured by only a single wall. May be.

  As described above in detail with reference to specific examples, the present invention opens the wall portion of the corner contact member when the corner contact member that protects the corner portion of the article is attached to or removed from the article. It is possible to suppress a problem that the surface or the back surface of the article is damaged by being rubbed or scraped at the side portion or the tip portion of the cut-and-raised piece for preventing falling off. The present invention is in the technical field of protection, packing, storage, and transportation of various articles, including interior products such as interior furniture such as interior doors and hanging doors, or interior furniture such as cabinets and table tops. Has wide industrial applicability.
