[Prior Art] There are various methods for mounting a display such as a poster on a board. For a kanban that mounts a poster in an unfolded state, a known technique is to attach one end of a belt-like mounting with a stretch to a poster. In the corner, the other end portion of the mounting member is attached to the display panel or the wall surface with an adhesive, whereby the poster is installed so as not to be slackened (for example, refer to Japanese Patent Laid-Open No. 61-86298, Japan Bulletin No. 56-75779). In addition, in order to prevent the revelation of a poster or the like from being slack due to moisture or the like, Japanese Laid-Open Patent Publication No. Hei-5-5-23-93 discloses a disclosure device having a belt-like telescopic portion that can correspond to a telescopic stretch of a poster, and is loaded. It is used in the corner of the reveal (poster). Further, the applicant of the present application has previously proposed a tension plate capable of maintaining the entire display state in an expanded state (refer to Japanese Patent No. 3161913), which is provided with a stretching fixing means which is fixedly held along the corners of the display piece. The tension is applied to the linear direction in which the inner corner of the corner portion is halved to apply the aforementioned tension between the corner portion of the frame supporting the tension plate of the display and the front end of the holder. In addition, there is a method of using a holder to unfold the display. However, the above-mentioned conventional use of an adhesive to mount a display (Revelation-4-(2)(2)1331735) reveals that 'the change in humidity or temperature reduces the adhesion of the adhesive and is prone to peeling. The unfolding effect of the object is deteriorated, and as a result, slack occurs and the display effect is deteriorated. In addition, with regard to the method of using the 挟 holder for the stretch mounting, the unfolding effect is insufficient, and the slack is generated as time changes. Further, although the deployment method of the display sheet of the above-mentioned Japanese Patent No. 3161913 can achieve a certain achievement, the development structure thereof needs to be further improved. Based on this, it is desirable to provide a stretching holding device which does not cause slack and wrinkles of the display due to environmental changes or the like in the display of the purpose of use, and maintains the display state during the display period. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a tension holding device for a tension plate, which can prevent a display attached to a plate from causing slack and wrinkles as time passes. , 俾 maintain a good state of expansion.

In the present invention, it is preferable that the outer fork portion is an L-shaped portion having a long leg length, and the inner fork portion is an L-shaped portion having a shorter leg length than the outer fork portion. Further, the ratio of the length of the outer fork portion to the length of the inner fork portion is preferably 100: 98 to 70. Further, it is preferable that the retaining body and the locking portion of the stretching and fixing means are either one of the locking holes and the other of which is an engaging projection or a locking hook that engages with the locking hole. Further, the stretching and fixing means may be formed by bending a wire and joining the end portions to each other, or by subjecting the plate material to etching or punching. In the present invention, the two-layer bifurcated stretch fixing means comprising the elastic material and consisting of the outer fork portion and the inner fork portion connected thereto is pivotally connected by the base end portion thereof The frame for mounting the display, and the locking portion provided at the central portion of the bifurcated portion on the inner side of the tensile fixing means is fixed in advance along the two edges of the corner portion of the display.

The tension plate 2 is attached to the locking hook 25 of the tensile fixture 20 attached to each corner portion of the frame 3, and the locking hole 11c of the protruding portion lib, 13b formed by the base of the holder 1 is attached. , 13c forms a snap. In this way, the latching hook 25 that acts on the tensile fixture 20 (located in the center of the two legs of the inner portion 23 of the double-layered L-shape) is provided in the elastic wire made of -10 - (8) (8) 1331735 At the intersection position), the inner portion 23 and the L-shaped outer portion 22 connected thereto act together to elastically deform the bifurcated foot portion outwardly. The reaction force generated by the elastic displacement is transmitted and blocked. The holder 10 to which the hook 25 is engaged exerts a developing force on the display 5. The operation of the stretching fixture 20 will be described using the operation explanatory diagram shown in Fig. 5. The tensile fixing member 20, as described above, combines two L-shaped outer portions 22 of different lengths of the elastic body (elastic wire) with the inner portion 23 and is integrally joined at the two ends, in the inner portion The central intersection position of the 23 (the locking hook 25) is engaged with the locking holes 13c, 11c of the holder 1b, whereby the tension of the display 5 acts in the direction of the arrow a (inner pull), the force thereof It will act separately toward the two leg portions 23a, 23a of the inner portion 23. At this time, the ends of the leg portions 22a and 22a of the outer portion 22 having the longer leg length L are joined than the leg length L' of the leg portions 23a and 23a of the inner portion 23, and the center of the inner portion 23 is joined. The intersection portion (the locking hook 25) is in a free state, and the base portion 24 of the outer portion 22 is in a state of being pivotally connected by the locking member 3, and for the side portion 22 not in the free state, the inner portion 23 in the free state has a moment mechanism. The action acts on the two leg portions 23a and 23a of the inner portion 23 to generate a rotational moment in the directions b and b from the base portion 24 starting from the base portion 22 to the two leg portions 22a and 22a of the outer portion 22. As a result, the two leg portions 23a, 22a of the inner and outer side portions 23, 22 are elastically displaced outwardly as shown by the broken line Q in the figure. The elastic stretcher 20 of the elastic system is elastically displaced by the force transmitted from the retainer 1 attached to the latching hook 25, and should be -11 - (9) 1331735. 10 is transmitted to the display 5, and the holder for holding the both edges of the corner portion of the display 5 generates stress in a linear direction which bisects the inner corner of the corner portion, and has a function of developing force. Further, in the above-described stretching fixture 20, since the left-hand symmetry is formed, the expansion force of the display 5 due to the elastic displacement is equally distributed in the direction in which the inner corners of the corner portions are equally divided, and the display 5 is initially set. The aforementioned deployment force will continue to function after the tensioning force. Therefore, even if the display is elongated due to environmental changes, it can be absorbed and maintained in an unfolded state. In order to investigate the relationship between the length of the inner portion and the outer portion of the tensile fixture 20, experiments were conducted on the following three samples. The contents of the experimental sample were applied with reference to Fig. 5, and the locking hooks 25 of the inner portion 23 were applied under the same conditions. The results are summarized in Table 1.

由實驗結果可確認出，不管是那個情形，只要施加些 微的張力，都會使拉伸固定具20大幅彈性移位，其反作 用力反而會對展示物5賦予張緊力（展開力）。再者也了 解到’當內側部分23與外側部分22之腳長差異小，雖彈 性移位倍率變大’但腳部之展開反而變大，腳部端在框架 3上之保持寬度變大’且造成使用上不方便。因此，基於 實用上的觀點，以實驗試料1或2的範圍爲佳。 此外’依據本實施形態之拉伸保持裝置1，即使張力 板2的框架3之縱橫比與展示物5之縱橫比不一致的情形 -13- (11) (11)1331735 ，或展示物5的端緣和框架3的端緣之距離與展示物5之 側緣和框架3的側緣之距離不同的情形，或展示物5之縱 長與橫長不同的情形，如第6圖所示，當前述拉伸固定具 2〇之基部樞接於樞支位置P，而連結該樞支位置P與卡止 位置c(保持具10的卡止孔13c、11c與拉伸固定具20的 卡止鉤25 (參照第2圖）之卡止位置）之直線f欲往將內 角二等分之40°角度以外的方向g移動時（圖中之虛線R )，拉伸固定具20之卡止位置c欲往卡止位置c’移動、 拉伸固定具20之兩腳端部22 A、22B欲往虛線所示之兩腳 端部（22A) 、（ 22B)的位置移動。然而，展示物5產生 之2~4mm的拉伸力，在兩腳端部22A、22B會以8~2 0倍 的擴大倍率將拉伸固定具20的兩腳部撐開，因此其中一 腳部會抵接於框架3之壁面3a，其反作用力會轉換成使拉 伸固定具20全體以樞支位置P爲基準旋動之旋動力。結 果，會使拉伸固定具20之卡止鉤25的卡止位置c，由移 位後之卡止位置c’返回原來的卡止位置c。此外，拉伸固 定具20會如圖中細線E所示，和前述同樣地將腳部擴開 而使張緊力透過保持具10作用於展示物5。 如此般，對於拉伸固定具20，展示物5之伸縮產生的 作用力方向位於將隅角部內角二等分的方向以外的情形， 只要其移動量在2〜3mm左右的距離，由於腳部之擴大倍 率爲8〜20倍，故可將拉伸固定具20的卡止位置恒控制在 接近45°。藉此，能對應於因環境改變所造成之展示物5 的中心位移，而能防止展示物5發生鬆弛與皴痕等。 -14- (12) (12)1331735 例如在500mmx700mm之片材（紙、樹脂薄膜、金屬 片）的四隅角施加張力，分別以〇.5~2· Okg的張力安裝於 框架時，在一般的氣候與室溫之環境變化中，框架側之拉 伸固定具20的樞支點與展示物的保持具10之卡止位置（ 卡止點）之伸縮量爲1〜2mm左右，這時拉伸固定具20之 腳部端的移位距離爲 10〜20mm，因此能在寬度 10mm~30mm之框架中被吸收。再者，前述展示物之卡止 位置（c’）會往接近內角1/2方向之位置c”移動，而從展 示物之隅角部朝兩外緣的方向持續施加展開力。因此，展 示物不會發生鬆弛與皺痕等，而能持續保持平滑的表面。 關於前述拉伸固定具，雖是說明將彈簧鋼線材彎曲加 工而形成者，但該彈性材也能使用方型截面之彈簧材或板 彈簧。此外，以高彈性之 SUS301CSP、SUS604CSP、 SUS 3 04WPB 材構成之直徑 0.2~1.5mm 的線材、厚度 0.2~ 1.5 mm的板彈簧材爲佳。視需要也能使用塑膠等的彈 性體。 此外，視需要，可將本實施形態之保持具10的卡止 孔11c、13c與拉伸固定具20之卡止鉤25做相反的配置 ，亦即在保持具1 〇側設置卡止鉤，在拉伸固定具20側設 置卡止孔。 在前述實施形態，拉伸固定具20係如第4 ( a ) ( b ) 圖所示，將彈簧鋼線材21彎曲成兩端部豎起再予以接合 而構成，但也能採用第7(a) (b)圖所示之實施形態。 第7(a)圖所示之拉伸固定具2 0A，係使用不鏽鋼彈 -15- (13) (13)1331735 簧線材21A (例如φ 1.5mm)，將內側的L字形部分2 3 A 之中央部彎成大致Μ字形，以中央之圓弧狀彎曲部作爲卡 止部25Α，將外側之L字形部分22Α之基部24Α做成方形 的縮頸狀。此外，第7(b)圖之拉伸固定具2 0Β，係使用 不鏽鋼彈簧板材21Β (例如厚度1.5mm)，藉由鈾刻或衝 壓等一體成形的方式製作出，在內側之L字形部分23 B的 中央部設置向內突出之具有孔的卡止部25B，以外側之L 字形部分22 B之基部24B作爲尖頭狀的卡止部。採用這種 一體成形的方式，能獲得更強的張力。此外，在該等實施 形態的情形，對應於卡止部25 A、25B，係在保持具10側 設置卡止突起或卡止鉤。 本發明之張力板之拉伸保持裝置，除了適用於將海報 、布條、光透過型薄膜展開而安裝於框架的用途外，也適 用於在製造軟性印刷基板時將其展開的用途等等。 【圖式簡單說明】 第1圖係採用本發明之一實施形態之拉伸保持裝置之 張力板之全體立體圖。 第2圖係前述張力板的主要部分之放大槪要圖。 第3(a)圖係顯示展示物的保持具的一部分之立體圖 ，第3(b)圖係顯示保持具之挾持具之挾持壓桿的解除態 樣之立體圖。 第4圖係顯示拉伸固定手段之拉伸固定具之立體圖（ a )與俯視圖（b )。 -16- (14)1331735 第5圖係本實施形態的拉伸保持裝置之動作說明圖。 第6圖係變形例的展示物之動作說明圖。 第7(a) 、 （b)圖係顯示拉伸固定具的其他實施形 態之俯視圖。 【主要元件符號說明】 1 :拉伸保持裝置From the experimental results, it was confirmed that, in any case, as long as a slight tension was applied, the tensile fixture 20 was largely elastically displaced, and the reverse force exerted a tension (expansion force) on the display 5. Further, it is also understood that 'the difference in the length of the foot between the inner portion 23 and the outer portion 22 is small, and although the elastic shift magnification becomes larger, the expansion of the foot becomes larger, and the width of the foot end on the frame 3 becomes larger. And it is inconvenient to use. Therefore, it is preferable to use the range of the experimental sample 1 or 2 based on a practical viewpoint. Further, according to the stretching holding device 1 of the present embodiment, even if the aspect ratio of the frame 3 of the tension plate 2 does not coincide with the aspect ratio of the display 5 - 13 - (11) (11) 1331735, or the end of the display 5 The distance between the edge and the edge of the frame 3 is different from the distance between the side edge of the display 5 and the side edge of the frame 3, or the case where the length and the horizontal length of the display 5 are different, as shown in Fig. 6, when The base of the tensile fixture 2 is pivotally connected to the pivotal position P, and connects the pivotal position P and the locking position c (the locking holes 13c, 11c of the holder 10 and the locking hook of the tensile fixture 20) 25 (refer to Fig. 2) The straight line f of the locking position is to move in the direction g other than the angle of 40° which is halved in the inner angle (the broken line R in the figure), and the locking position of the tensile fixture 20 is stretched. c. To move to the locking position c', the two end portions 22A, 22B of the extension fixture 20 are moved to the positions of the two end portions (22A) and (22B) indicated by the broken lines. However, the stretching force of 2 to 4 mm generated by the display 5 causes the two leg portions of the stretching fixture 20 to be expanded at an expansion ratio of 8 to 20 times at the end portions 22A and 22B of the both legs, so that one of the legs is extended. The portion abuts against the wall surface 3a of the frame 3, and the reaction force is converted into a rotational force that causes the entire tensile fixture 20 to be rotated with respect to the pivotal position P. As a result, the locking position c of the locking hook 25 of the stretching fixture 20 is returned to the original locking position c by the locking position c' after the displacement. Further, as shown by the thin line E in the figure, the stretching fixture 20 expands the leg portion in the same manner as described above, and causes the tensioning force to pass through the holder 10 to act on the display member 5. In the same manner, in the stretching fixture 20, the direction of the force generated by the expansion and contraction of the display 5 is outside the direction in which the inner corner of the corner portion is equally divided, as long as the amount of movement is about 2 to 3 mm, due to the foot. Since the expansion magnification is 8 to 20 times, the locking position of the tensile fixture 20 can be constantly controlled to be close to 45°. Thereby, it is possible to prevent the display 5 from being slackened, scarred, and the like in accordance with the center displacement of the display 5 due to environmental changes. -14- (12) (12) 1331735 For example, when a tension is applied to the four corners of a sheet of 500 mm x 700 mm (paper, resin film, metal sheet), the tension is applied to the frame at a tension of 〇5~2·0 kg, respectively. In the environmental change of the climate and the room temperature, the amount of expansion and contraction of the pivot point of the stretch fixture 20 on the frame side and the retaining position of the holder 10 of the display (locking point) is about 1 to 2 mm, and the stretch fixture is used. The displacement of the foot end of 20 is 10 to 20 mm, so it can be absorbed in a frame having a width of 10 mm to 30 mm. Further, the locking position (c') of the display is moved to a position c" close to the inner angle 1/2 direction, and the deployment force is continuously applied from the corner portion of the display toward the outer edges. The display material does not have slacks, wrinkles, etc., and can maintain a smooth surface. The above-mentioned tensile fixture has been described as being formed by bending a spring steel wire, but the elastic material can also use a square cross section. A spring material or a leaf spring. It is preferably a wire material having a diameter of 0.2 to 1.5 mm and a plate spring material having a thickness of 0.2 to 1.5 mm, which are made of SUS301CSP, SUS604CSP, and SUS 3 04WPB, which are highly elastic. Further, if necessary, the locking holes 11c and 13c of the holder 10 of the present embodiment may be arranged opposite to the locking hooks 25 of the stretching fixture 20, that is, the card may be disposed on the side of the holder 1 In the hook, the locking hole is provided on the side of the tensile fixture 20. In the above embodiment, the tensile fixture 20 is bent as shown in the fourth (a) (b) diagram, and the spring steel wire 21 is bent at both ends. It is constructed by joining and joining, but it is also possible to adopt 7(a) (b) The embodiment shown in the figure. The tensile fixture 20A shown in Fig. 7(a) is made of stainless steel elastic -15-(13) (13) 1331735 spring wire 21A (for example, φ 1.5 mm). The central portion of the inner L-shaped portion 2 3 A is bent into a substantially U-shape, and the arcuate curved portion at the center is used as the locking portion 25Α, and the base portion 24 of the outer L-shaped portion 22 is formed into a square neck shape. Further, the stretching fixture of Fig. 7(b) is made of a stainless steel spring plate 21 (for example, a thickness of 1.5 mm), and is integrally formed by uranium engraving or punching, and an L-shaped portion 23 on the inner side. The central portion of B is provided with a locking portion 25B having a hole projecting inward, and the base portion 24B of the outer L-shaped portion 22B is a pointed-shaped locking portion. By adopting such an integral forming method, a stronger one can be obtained. Further, in the case of the above embodiments, the locking projections 25A and 25B are provided with the locking projections or the locking hooks on the holder 10 side. The tension holding device of the tension plate of the present invention is applicable. It is also suitable for the purpose of attaching posters, cloth strips, and light transmissive films to the frame.
