この発明は、三角パーツに関し、特にたとえば、ファイル、バインダおよびクリップボードなどの板状部材の角部を被覆する三角パーツに関する。   The present invention relates to a triangular part, and more particularly to a triangular part that covers corners of plate-like members such as files, binders, and clipboards.

図7は、従来のクリップボードの一例を示す平面図である。クリップボード1は、厚紙で形成された長方形状の板材2を含む。板材2の長手方向の中央部において、板材2の一方の端部に、紙挟み部3が形成される。この紙挟み部3に紙を挟んで保持することにより、紙上に文字や図面等を記載することができる。   FIG. 7 is a plan view showing an example of a conventional clipboard. The clipboard 1 includes a rectangular plate material 2 formed of cardboard. A paper sandwiching portion 3 is formed at one end of the plate 2 at the center in the longitudinal direction of the plate 2. By holding and holding the paper between the paper sandwiching portions 3, characters, drawings, and the like can be written on the paper.

このクリップボード1では、板材2の4つの角隅部に、金属製の角金具4が取り付けられている。角金具4は、板材2の角隅部の形状に合わせて、円弧状部を挟んで互いに直交する向きに延びる2つの直線部を有する。角金具4は、その断面が半円形状または馬蹄形状等に形成され、板材2の角隅部の両面および端面を覆うように取り付けられる。角金具4の円弧状部および直線部において、板材2の向きに角金具4を押圧することにより、角金具4は板材2に咬み込み、角金具4が板材2の4つの角隅部に固定される。   In the clipboard 1, metal square brackets 4 are attached to four corners of the plate 2. The square bracket 4 has two straight portions that extend in directions orthogonal to each other across the arc-shaped portion, in accordance with the shape of the corner portion of the plate 2. The square bracket 4 has a cross section formed in a semicircular shape or a horseshoe shape, and is attached so as to cover both sides and end faces of the corners of the plate member 2. By pressing the square bracket 4 in the direction of the plate 2 at the arc-shaped portion and the straight portion of the square bracket 4, the square bracket 4 is bitten into the plate 2, and the square bracket 4 is fixed to the four corners of the plate 2.

しかしながら、このような従来の角金具では、板材の角隅部に角金具を嵌め込んだ後にかしめるという作業が必要であり、板材への角金具の取り付けが大変であった。また、角金具が取り付けられた板材は保護されるが、板材の近傍にある書類やファイル等に角金具がぶつかると、書類やファイル等が傷つく可能性がある。   However, in such a conventional square metal fitting, it is necessary to perform the work of caulking after fitting the square metal fitting into the corner of the plate material, and it is difficult to attach the square metal fitting to the plate material. Further, although the plate member to which the square bracket is attached is protected, if the square bracket collides with a document or file near the plate member, the document or file may be damaged.

それゆえに、この発明の主たる目的は、板材の角部に容易に取り付けることができ、板材の角部を保護することができるとともに、板材の近傍にある書類やファイルを傷付けることを防ぐことができる三角パーツを提供することである。   Therefore, the main object of the present invention is to easily attach to the corners of the plate material, protect the corner portions of the plate material, and prevent damage to documents and files in the vicinity of the plate material. It is to provide triangular parts.

この発明は、角部を有する板材の角部近傍を被覆する弾性材料で形成された三角パーツであって、板材の角部近傍の両主面および板材の角部の少なくとも先端部を含む端面を被覆し、板材の角部近傍において、板材の角部を頂点とする架空の二等辺三角形の底面に略平行に板材に形成された凹部に嵌め込まれる凸部が内部に形成された、三角パーツである。
板材の角部を頂点とする架空の二等辺三角形の底面に略平行に形成された凹部に嵌め込まれる凸部が弾性材料で形成された三角パーツの内部に形成されているため、三角パーツを板材の角部に被せることにより、三角パーツの凸部が板材の凹部に嵌まり込む。三角パーツの凸部は板材の角部を頂点とする架空の二等辺三角形の底面に略平行に形成された凹部に嵌め込まれるため、三角パーツを板材の角部方向に引っ張っても外れにくい。ここで、板材の角部を頂点とする架空の二等辺三角形とは、板材の角部を頂点として、その両側において板材の隣接する2つの辺に沿った等しい長さを有する2辺を含む想像上の三角形とことである。このとき、三角パーツが弾性材料で形成されていることにより、三角パーツ内部で凸部の近傍が変形して、板材の凹部に凸部を嵌め込むことができる。三角パーツは、弾性材料で形成されているため、板材の角部を保護することができるとともに、板材の角部が板材の周辺の書類やファイルに当たっても、これらの書類やファイルの破損を防止することができる。
The present invention is a triangular part formed of an elastic material that covers the vicinity of a corner of a plate having a corner, and includes both main surfaces in the vicinity of the corner of the plate and an end surface including at least the tip of the corner of the plate. A triangular part that is covered and formed with a convex part that fits into a concave part formed in the plate material approximately parallel to the bottom surface of an imaginary isosceles triangle with the corner portion of the plate material as a vertex in the vicinity of the corner portion of the plate material. is there.
Since the convex part that fits into the concave part formed almost parallel to the bottom of an imaginary isosceles triangle with the corner of the plate as the apex is formed inside the triangular part made of elastic material, the triangular part is made of plate By covering the corners, the convex parts of the triangular parts fit into the concave parts of the plate material. Since the convex part of the triangular part is fitted into a concave part formed substantially in parallel with the bottom surface of an imaginary isosceles triangle having the corner of the plate as the apex, it is difficult to come off even if the triangular part is pulled in the direction of the corner of the plate. Here, the fictitious isosceles triangle with the corner of the plate as an apex is an imaginary including two sides having equal length along two adjacent sides of the plate with the corner of the plate as the apex. That is the upper triangle. At this time, since the triangular part is formed of an elastic material, the vicinity of the convex part is deformed inside the triangular part, and the convex part can be fitted into the concave part of the plate material. Triangular parts are made of elastic material, so that the corners of the plate can be protected, and even if the corners of the plate hit the documents and files around the plate, they are prevented from being damaged. be able to.

このような三角パーツにおいて、板材の角部に取り付けられたとき、凸部は、板材の角部を頂点とする架空の二等辺三角形の底辺に対して角部から下ろされる垂線に対して対称となるように形成されることが好ましい。
板材の角部を頂点とする架空の二等辺三角形の底辺に対して角部から下ろされる垂線に対して対称となるように三角パーツの凸部が形成されることにより、板材の角部の両側の対向する位置において、均一に三角パーツが固定される。そのため、板材の角部を被覆するようにして、安定した状態で三角パーツを板材の角部に取り付けることができる。
In such a triangular part, when attached to the corner of the plate material, the convex portion is symmetrical with respect to a perpendicular drawn from the corner with respect to the base of an imaginary isosceles triangle having the corner of the plate material as a vertex. It is preferable to be formed as follows.
Both sides of the corners of the plate are formed by forming the convex parts of the triangular parts so that they are symmetrical with respect to the perpendicular line drawn from the corners with respect to the base of an imaginary isosceles triangle with the corners of the plate as the vertex The triangular parts are uniformly fixed at the positions facing each other. Therefore, the triangular part can be attached to the corner of the plate in a stable state so as to cover the corner of the plate.

また、凸部は、板材の端面に対して少なくとも内側から外側に向かって突出する凸部であることが好ましい。
三角パーツの凸部を板材の端面に対して少なくとも内側から外側に向かって突出する凸部とすることにより、板材の角部方向に向かって三角パーツを引っ張っても、三角パーツの内部で凸部が板材の凹部に嵌め込まれているため、三角パーツと板材との間に強固な結合を得ることができる。
Moreover, it is preferable that a convex part is a convex part which protrudes toward an outer side at least with respect to the end surface of a board | plate material.
By making the convex part of the triangular part protrude at least from the inside to the outside with respect to the end face of the plate material, even if the triangular part is pulled in the corner direction of the plate material, the convex part is inside the triangular part. Is fitted in the concave portion of the plate material, a strong bond can be obtained between the triangular part and the plate material.

この発明によれば、板材の角部に三角パーツを被せるだけで、容易に弾性を有する三角パーツで板材の角部を被覆することができる。したがって、板材の角部を保護することができるとともに、板材の近傍にある書類やファイルを傷つけることを防止することができる。さらに、三角パーツの内部において、板材の凹部に三角パーツの凸部が嵌まり込んでいるため、三角パーツが板材から外れにくい。   According to this invention, the corner | angular part of a board | plate material can be easily coat | covered with the triangular part which has elasticity only by covering a triangular part on the corner | angular part of a board | plate material. Therefore, it is possible to protect the corners of the plate material and to prevent the documents and files in the vicinity of the plate material from being damaged. Furthermore, since the convex part of the triangular part is fitted in the concave part of the plate material inside the triangular part, the triangular part is not easily detached from the plate material.

The internal slope portions 98a and 98b are formed to have substantially the same length as the slope portions 34a and 34b of the first bowl-shaped portion 32, and the suspension portions 100a and 100b are formed from the end portions toward the base of the isosceles triangle. Is done.

懸垂部100a,100bの先端部には、それぞれ三角パーツ90の2つの端面94a,94bの外側に向かって突出する凸部102a,102bが形成される。凸部102a,102bは、三角パーツ90の頂点から底辺に下ろした垂線に略直交する台座部104a,104bを含む。台座部104a,104bは、第2の茸状部50の裏面60bおよび第3の茸状部70の裏面80bと略等しい寸法に形成される。台座部104a,104bに連結されるようにして、第2の茸状部50の平行側部62b、傾斜部64bおよび第3の茸状部70の平行側部82b、傾斜部84bに対応する形状の側面部106a,106bが形成され、それに続いて略円弧状の底面部108a,108bが形成される。   Convex portions 102a and 102b projecting outward from the two end surfaces 94a and 94b of the triangular part 90 are formed at the tip portions of the suspension portions 100a and 100b, respectively. The convex portions 102 a and 102 b include pedestal portions 104 a and 104 b that are substantially orthogonal to a perpendicular line extending from the apex of the triangular part 90 to the bottom side. The pedestal portions 104a and 104b are formed to have substantially the same dimensions as the back surface 60b of the second hook-shaped portion 50 and the back surface 80b of the third hook-shaped portion 70. Shapes corresponding to the parallel side portion 62b of the second hook-shaped portion 50, the inclined portion 64b, the parallel side portion 82b of the third hook-shaped portion 70, and the inclined portion 84b so as to be connected to the pedestal portions 104a and 104b. Side surfaces 106a and 106b are formed, and subsequently, substantially arc-shaped bottom surfaces 108a and 108b are formed.

さらに、三角パーツ90の端面に形成された孔96a,96bの下端から内側に向かって、側面凸部110a,110bが形成される。側面凸部110a,110bは、第1の茸状部32の先端部36を頂点とする架空の二等辺三角形の底辺に下ろした垂線に略直交する台座部112a,112bを含む。台座部112a,112bは、第2の茸状部50の裏面60aおよび第3の茸状部70の裏面80aと略等しい寸法に形成される。台座部112a,112bに連結されるようにして、第2の茸状部50の平行側部62a、傾斜部64aおよび第3の茸状部70の平行側部82a、傾斜部84aに対応する形状の側面部114a,114bが形成され、それに続いて底面部116a,116bが三角パーツ90の端面94a,94bの内側に連結される。   Furthermore, side convex portions 110a and 110b are formed inward from the lower ends of the holes 96a and 96b formed in the end surface of the triangular part 90. The side convex portions 110a and 110b include pedestal portions 112a and 112b that are substantially orthogonal to a perpendicular line drawn to the base of an imaginary isosceles triangle having the tip 36 of the first bowl-shaped portion 32 as a vertex. The pedestal portions 112 a and 112 b are formed to have substantially the same dimensions as the back surface 60 a of the second flange-shaped portion 50 and the back surface 80 a of the third flange-shaped portion 70. A shape corresponding to the parallel side portion 62a of the second hook-shaped portion 50, the inclined portion 64a and the parallel side portion 82a of the third hook-shaped portion 70, and the inclined portion 84a so as to be connected to the pedestal portions 112a and 112b. Side surfaces 114a and 114b are formed, and subsequently the bottom surface portions 116a and 116b are connected to the inside of the end surfaces 94a and 94b of the triangular part 90.

三角パーツ90は、板材10の三角パーツ取付部30に取り付けられる。このとき、三角パーツ取付部30を被覆するようにして、三角パーツ90が板材10の角部に被せられる。この場合、三角パーツ90は弾性材料で形成されているため、図5に示すように、懸垂部100a,100bや側面凸部110a,110bの近傍が、三角パーツ取付部30の各部の形状に応じて変形する。   The triangular part 90 is attached to the triangular part attaching part 30 of the plate member 10. At this time, the triangular part 90 is put on the corner portion of the plate 10 so as to cover the triangular part mounting portion 30. In this case, since the triangular part 90 is formed of an elastic material, as shown in FIG. 5, the vicinity of the suspended parts 100 a and 100 b and the side surface convex parts 110 a and 110 b depends on the shape of each part of the triangular part mounting part 30. And deform.

まず、三角パーツ90を三角パーツ取付部30に被せて押し込んでいくと、懸垂部100a,100bの凸部102a,102bの側面部106a,106bが第2の茸状部50の内側の斜面部54bおよび第3の茸状部70の内側の斜面部74bに当たる。しかしながら、凸部102a,102bの側面部106a,106bと第2の茸状部50の斜面部54b、第3の茸状部70の斜面部74bとが略平行に形成されているため、懸垂部100a,100bが互いに近づくように変形しながら、凸部102a,102bが斜面部54b,74b上を滑っていく。そして、凸部102a,102bが第2の茸状部50の内側の平行端部56bおよび第3の茸状部70の内側の平行端部76bを超えたとき、凸部102a,102bが第2の茸状部50の内側の凹部58bおよび第3の茸状部70の内側の凹部78bに嵌まり込む。したがって、第1の茸状部32のくびれ部40a,40bは、それぞれ、凸部102aが第2の茸状部50の平行端部56bと並んだとき、および凸部102bが第3の茸状部70の平行端部76bと並んだときの幅より大きい隙間を有している必要がある。   First, when the triangular part 90 is pushed over the triangular part mounting portion 30, the side surface portions 106 a and 106 b of the projecting portions 102 a and 102 b of the suspension portions 100 a and 100 b are inclined surfaces 54 b inside the second bowl-shaped portion 50. And it hits the slope part 74b inside the 3rd bowl-shaped part 70. FIG. However, since the side surface portions 106a and 106b of the convex portions 102a and 102b, the inclined surface portion 54b of the second flange-shaped portion 50, and the inclined surface portion 74b of the third flange-shaped portion 70 are formed substantially in parallel, the suspended portion The convex portions 102a and 102b slide on the slope portions 54b and 74b while being deformed so that the portions 100a and 100b approach each other. And when the convex parts 102a and 102b exceed the parallel end part 56b inside the second hook-shaped part 50 and the parallel end part 76b inside the third hook-shaped part 70, the convex parts 102a and 102b are the second It fits in the recessed part 58b inside the bowl-shaped part 50, and the recessed part 78b inside the third bowl-shaped part 70. Accordingly, the constricted portions 40a and 40b of the first hook-shaped portion 32 are respectively formed when the convex portion 102a is aligned with the parallel end portion 56b of the second hook-shaped portion 50 and the convex portion 102b is a third hook-shaped portion. It is necessary to have a gap larger than the width when aligned with the parallel end portion 76 b of the portion 70.

同様に、三角パーツ90を三角パーツ取付部30に嵌め込むときに、その対向面92a,92bおよび端面94a,94bが変形しながら、側面凸部110a,110bが第2の茸状部50の外側の斜面部54aおよび第3の茸状部70の外側の斜面部74aをすべって、外側の凹部58a,78aに嵌まり込む。   Similarly, when the triangular part 90 is fitted into the triangular part mounting portion 30, the side surface convex portions 110 a and 110 b are outside the second hook-shaped portion 50 while the opposing surfaces 92 a and 92 b and the end surfaces 94 a and 94 b are deformed. The slope part 54a and the slope part 74a on the outside of the third bowl-like part 70 are slipped and fitted into the outside recesses 58a and 78a.

このとき、図6に示すように、懸垂部100a,100bの凸部102a,102bと第2の茸状部50の凹部58b、第3の茸状部70の凹部78bとが対応した形状を有するため、懸垂部100aの凸部102aと第2の茸状部50の凹部58bとがほぼ隙間なく嵌り合い、懸垂部100bの凸部102bと第3の茸状部70の凹部78bとがほぼ隙間なく嵌り合う。同様に、三角パーツ90の端面94a,94bの内側に形成された側面凸部110a,110bと第2の茸状部50の凹部58a、第3の茸状部70の凹部78aとが対応した形状を有するため、側面凸部110aと第2の茸状部50の凹部58aとがほぼ隙間なく嵌り合い、側面凸部110bと第3の茸状部70の凹部78aとがほぼ隙間なく嵌り合う。さらに、三角パーツ90の内部において、三角パーツ取付部30の第1の茸状部32の斜面部34a,34bと三角パーツ90の端面94a,94bの内側とがほぼ隙間なく配置される。   At this time, as shown in FIG. 6, the protrusions 102a and 102b of the suspension parts 100a and 100b, the recess 58b of the second hook-like part 50, and the recess 78b of the third hook-like part 70 have corresponding shapes. Therefore, the convex part 102a of the suspension part 100a and the concave part 58b of the second hook-like part 50 fit with each other with almost no gap, and the convex part 102b of the suspension part 100b and the concave part 78b of the third hook-like part 70 are almost gap. Fits together. Similarly, the side protrusions 110a, 110b formed inside the end faces 94a, 94b of the triangular part 90, the recesses 58a of the second hook-like part 50, and the recesses 78a of the third hook-like part 70 correspond to each other. Therefore, the side convex portion 110a and the concave portion 58a of the second hook-like portion 50 fit with each other with almost no gap, and the side convex portion 110b and the concave portion 78a of the third hook-like portion 70 fit with almost no gap. Further, inside the triangular part 90, the slopes 34a and 34b of the first hook-shaped part 32 of the triangular part mounting part 30 and the insides of the end faces 94a and 94b of the triangular part 90 are arranged with almost no gap.

第2の茸状部50の裏面60a,60b、三角パーツ90の台座部104a,104b,112a,112bは、それぞれ、第1の茸状部32の先端部36から底辺に下ろされた垂線に対して直交するように形成されているため、三角パーツ90が板材10の三角パーツ取付部30に取り付けられると、容易に離脱することはない。また、三角パーツ90を三角パーツ取付部30に嵌め込むだけで、三角パーツ90の各部が変形して嵌め込まれるため、三角パーツ90を容易に板材10に取り付けることができる。   The back surfaces 60a and 60b of the second hook-shaped part 50 and the pedestal parts 104a, 104b, 112a and 112b of the triangular part 90 are respectively perpendicular to the bottom line from the tip 36 of the first hook-shaped part 32. Therefore, when the triangular part 90 is attached to the triangular part attaching portion 30 of the plate member 10, it is not easily detached. Moreover, since each part of the triangular part 90 is deformed and fitted only by fitting the triangular part 90 into the triangular part attaching part 30, the triangular part 90 can be easily attached to the plate member 10.

三角パーツ90は弾性材料で形成されているため、板材10の端部を保護することができる。また、板材10を用いたファイルなどの近傍に用紙や他のファイルがあっても、板材10の角部で傷つけられる可能性が少なくなる。   Since the triangular part 90 is formed of an elastic material, the end of the plate member 10 can be protected. Further, even if there is a sheet or other file in the vicinity of a file using the plate 10, the possibility of being damaged at the corner of the plate 10 is reduced.

また、三角パーツ90を三角パーツ取付部30に被せるだけで板材10の端部を三角パーツ90で被覆することができ、しかも、三角パーツ90が板材10から外れにくい構造とすることができる。   Further, the end of the plate member 10 can be covered with the triangular part 90 only by covering the triangular part 90 on the triangular part mounting portion 30, and the triangular part 90 can be structured not to easily come off the plate member 10.

なお、上述の実施形態では、2つの茸状部50,70に形成された凹部58a,58b,78a,78bに凸部102a,102bおよび側面凸部110a,110bが嵌まり込む構造が採用されているが、例えば、第1の茸状部32に凹部を形成し、この凹部に嵌まり込む凸部を備えた三角パーツとしてもよい。このように、三角パーツ取付部30への三角パーツ90の取り付け構造は、自由に設計することができる。   In the above-described embodiment, a structure is employed in which the convex portions 102a, 102b and the side convex portions 110a, 110b are fitted into the concave portions 58a, 58b, 78a, 78b formed in the two bowl-shaped portions 50, 70. However, for example, a concave part may be formed in the first hook-like part 32, and a triangular part having a convex part that fits into the concave part may be used. Thus, the attachment structure of the triangular part 90 to the triangular part attaching part 30 can be designed freely.
