Abstract

To provide a propped support in which no stretching force is impaired by an excessive load while, conventionally, when an excessive load beyond an assumed use range is on the center part of a crimping rod, and when the rigidity of the crimping rod is unbearable to the load, the crimping rod bends in the load direction and finally slips down from the wall surface inconveniently.SOLUTION: In the event that an excessive load is added to the support and that the length between both ends of the support is shortened by bending and about to slip downward, holding parts slide along the tapered faces T1, T2 of abutment parts and move in a direction receding from the wall face, so that the shortened length portion between both ends of the support is absorbed as a result. The tapered faces are provided in a position away from the wall face from the contact position between the end face of the support and the holding part. Consequently, a stretching force which pushes back in the extending direction through the tapered faces works without being weakened to generate friction resistance, with an effect obtained which prevents the slipping down of the support.SELECTED DRAWING: Figure 5

Description

本発明は、突っ張り力により壁面間に圧着固定される支持体に関する。   The present invention relates to a support that is fixed by pressure between wall surfaces by a tension force.

例えば、押入れや廊下等で、釘や木ねじを使用できないような場所において壁面間に突っ張り力をもって圧着固定される突っ張り棒やこれを複数本備えた突っ張り棚が広く知られている。
本発明では、上記の突っ張り棒類と突っ張り棚類を総称して突っ張り支持体と記載した。 For example, in a place where nails or wood screws cannot be used, for example, in a closet or a corridor, there are widely known strut bars which are crimped and fixed with a strut force between wall surfaces, and strut shelves provided with a plurality thereof.
In the present invention, the above-mentioned strut bars and strut shelves are collectively described as strut supports.

しかし、上記の突っ張り支持体には次のような問題点があった。先ず、突っ張り支持体全般の問題点として、壁面間への保持を一定の突っ張り力による摩擦抵抗によっているので例えば、過度の負荷が加わった場合にはこの負荷が摩擦抵抗に打ち勝って突っ張り支持体が壁面よりずり落ちてしまう不都合があった。 However, the above-mentioned strut support has the following problems. First, as a general problem of the tension support, since the holding between the walls is performed by frictional resistance due to a constant tension, for example, when an excessive load is applied, this load overcomes the frictional resistance and the tension support is There was an inconvenience of slipping off the wall.

また、突っ張り支持体には、支持体の長さを調整する事で、その突っ張り力を調節する種類のものが存するが（公知例としては特許文献１）、この場合には振動等によって支持体の長さ調整機構部が縮小方向に緩み、遂には壁面よりずり落ちてしまう不都合があった。   In addition, there is a type of tension support in which the tension is adjusted by adjusting the length of the support (see Patent Document 1 as a known example). There is a disadvantage that the length adjusting mechanism section is loosened in the shrinking direction and eventually slips off the wall.

以上の問題点を解消した公知発明として特許文献２に記載の圧着棒が存する。図１にこの圧着棒の詳細を示す。圧着棒の一端又は両端に圧着棒が回転自在に保持される保持部３０、５０を設けると共に、圧着棒と保持部の摺動面には両者の密着時に圧着棒の伸長方向の回転のみを許すラチエット機構Ｒ１、Ｒ２を設け、更に片側を壁面への当接面とすると共に、他側をテーパー面に構成した当接部４０、６０を一対用意し、これらのテーパー面を接触面として、当接部を圧着棒又は圧着棒及び保持部に摺動自在に設けてある。この圧着棒の棒体２０は外筒１０の内に進退自在に挿入し、この内筒内部および外筒内部にコイルばねＳを挿入し、このコイルばねＳの一端を外筒１０のピン１２に固定するし、棒体２０の内部にこのコイルばねに螺合自在に係合するピン状のガイド部材２２を設けることにより、棒体を外筒に対し伸長方向の弾性力をもって螺合手段により進退自在に設けてある。この機構で棒体２０を回転することにより、外筒１０の内を棒体２０が進退し、ガイド部材２２はコイルばねＳによって支持されるので棒体２０の進退に応じた弾性力（突っ張り力）をもって圧着固定する事となる。   As a known invention that has solved the above problems, there is a pressure bonding rod described in Patent Document 2. FIG. 1 shows the details of the crimping bar. At one end or both ends of the crimping bar, holding portions 30 and 50 are provided for rotatably holding the crimping bar, and the sliding surfaces of the crimping bar and the holding portion allow only rotation in the extension direction of the crimping bar when the two are in close contact. The ratchet mechanisms R1 and R2 are provided, and a pair of abutting portions 40 and 60 each having a tapered surface on one side and a taper surface on the other side are prepared, and these tapered surfaces are used as contact surfaces. The contact portion is slidably provided on the crimping bar or the crimping bar and the holding portion. The crimping rod 20 is inserted into the outer cylinder 10 so as to be able to advance and retreat, a coil spring S is inserted into the inner cylinder and the outer cylinder, and one end of the coil spring S is inserted into the pin 12 of the outer cylinder 10. The pin is fixed and provided with a pin-shaped guide member 22 which is screwably engaged with the coil spring inside the rod 20, so that the rod is advanced and retracted by the screwing means with an elastic force in the extending direction with respect to the outer cylinder. It is provided freely. By rotating the rod 20 by this mechanism, the rod 20 advances and retreats in the outer cylinder 10, and the guide member 22 is supported by the coil spring S, so that the elastic force (stretching force) according to the advance and retreat of the rod 20. ) To fix by crimping.

図中符号６０は当接部であり、保持部５０を介して前記の棒体２０に連結される。この当接部６０は片側を壁面Ｗへの当接面とすると共に、他側を下方に向かうに従い壁面から離隔するテーパー面としたものであり、上記の保持部５０の一端に設けた摺動子５１をテーパー面側に設けた摺動溝６１に抜け止め手段をもって摺嵌することにより、保持部５０はテーパー面に対し摺動自在に設けられる。   In the figure, reference numeral 60 denotes a contact portion, which is connected to the rod 20 via the holding portion 50. The contact portion 60 has one side as a contact surface with the wall surface W, and the other side as a tapered surface separated from the wall surface as it goes downward, and is provided at one end of the holding portion 50. The holding portion 50 is provided slidably with respect to the tapered surface by sliding the child 51 into the sliding groove 61 provided on the tapered surface side with a retaining means.

この圧着棒は壁面Ｗ、Ｗ間に突っ張り力をもって圧着固定される。保持部５０はそれぞれ当接部６０に摺動自在に設けられているので、圧着棒に過度の荷重が加わって下方にずり落ちようとした場合には、その端部は下方に向かうに従い壁面から離隔する当接部のテーパー面を摺動する結果、縮小方向に移動するので、それを伸長方向に押し戻そうという弾性力（突っ張り力）により、より強い摩擦抵抗が生じてずり落ちが防止されることとなる（図２〜図３参照）。   This crimping rod is crimped and fixed between the wall surfaces W, W with a tensile force. Since the holding portions 50 are slidably provided on the abutment portions 60, respectively, when an excessive load is applied to the crimping bar and the crimping bar is slid downward, the end portion is moved downward from the wall surface. As a result of sliding on the tapered surface of the abutting portion that separates, the member moves in the contracting direction, and the elastic force (stretching force) of pushing it back in the elongating direction generates stronger frictional resistance and prevents slipping down. (See FIGS. 2 and 3).

前記の特許文献２記載の圧着棒は使用想定範囲内で、当接部のテーパー面により、圧着棒のずり落ちを防止する効果がある。しかしながら、圧着棒の中央部分に使用想定範囲を越える過度の荷重がかかり、かつ圧着棒の剛性がそれに耐えきれない場合は、図４に示すように圧着棒が荷重方向に撓み、その全長が短くなる現象を生じる可能性があった。この場合、保持部５０はその一端に設けた摺動子５１が抜け止め手段をもって当接部６０に摺嵌されているので、圧着棒の撓みに伴い当接部が壁面から離れる方向に引っ張られ、遂には壁面よりずり落ちてしまう不都合があった。 The crimping rod described in Patent Literature 2 has an effect of preventing the crimping rod from sliding down due to the tapered surface of the abutting portion within the expected use range. However, when an excessive load exceeding the expected use range is applied to the central portion of the crimping bar and the rigidity of the crimping bar cannot withstand it, the crimping bar is bent in the load direction as shown in FIG. Could occur. In this case, since the slider 51 provided at one end of the holding portion 50 is slidably fitted to the abutting portion 60 with a retaining means, the abutting portion is pulled in a direction away from the wall surface with the bending of the pressure rod. Finally, there was the inconvenience of slipping off the wall.

本発明は、前記従来技術の問題点改善のため創作したもので、使用想定範囲を越える過度の荷重がかかっても突っ張り力を損なわない突っ張り支持体を提供する事を課題とする。   SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art, and it is an object of the present invention to provide a strut support that does not impair the strut force even when an excessive load exceeding an expected use range is applied.

本発明は、前記従来技術の問題点改善のため創作したもので、荷重により撓んでも突っ張り力を損なわない突っ張り支持体を提供することを目的とする。 SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a strut support that does not impair the strut force even when flexed by a load.

図５に本発明の構成を示す。支持体７０と、支持体の両端に配され伸長方向の突っ張り力を伝える保持部と当接部と、が壁面間に突っ張り力をもって圧着固定される。突っ張り支持体は、支持体を保持し突っ張り力を当接部に伝える保持部３０，５０と保持部から壁面へ突っ張り力を伝える当接部４０，６０を設ける構成とし、上記保持部は片側面で支持体の端面と接する面を有し他側面で当接部と接する面を有し、上記当接部は片側面で保持部と接する面を有し他側面で壁面と接する面を有し、上記保持部と上記当接部の接する面は下方に向かうに従い壁面から離隔するテーパー面Ｔ１，Ｔ２に構成して設け、上記支持体の端面と上記保持部との接触面位置より壁面から離れた位置に上記テーパー面を設け、上記当接部を上記支持体又は支持体及び上記保持部に摺動自在に設けたことを特徴とする。 FIG. 5 shows the configuration of the present invention. The support 70 and the holding portions and the contact portions, which are disposed at both ends of the support and transmit the tensile force in the extension direction, are fixed by pressure between the wall surfaces with the tensile force. The strut support has a structure in which holding portions 30 and 50 for holding the support and transmitting the striking force to the contact portion and contact portions 40 and 60 for transmitting the striking force from the holding portion to the wall surface are provided. Has a surface in contact with the end face of the support, has a surface in contact with the contact portion on the other side, and the contact portion has a surface in contact with the holding portion on one side and a surface in contact with the wall surface on the other side The surface where the holding portion and the contact portion are in contact with each other is formed as tapered surfaces T1 and T2 which are separated from the wall surface as going downward, and is separated from the wall surface from the contact surface position between the end surface of the support and the holding portion. The tapered surface is provided at a position where the contact portion is located, and the contact portion is slidably provided on the support or the support and the holding portion.

棚板と棚板の両端に配され伸長方向の突っ張り力を伝える保持部と当接部と、が壁面間に突っ張り力をもって圧着固定される突っ張り棚も本発明の突っ張り支持体と同様の構造である事を実施例で開示する。   The holding shelf and the abutting portion, which are arranged on both ends of the shelf and the shelf and transmit the stretching force in the extension direction, are fixed by pressure between the walls with a stretching force. Some things will be disclosed in the examples.

本発明の突っ張り支持体によれば、図６に示す様に支持体７０に過度の荷重が加わって仮に支持体が撓んでその支持体の両端部間の長さが撓み無い状態の長さＬ１から撓んだ状態の長さＬ２へと短くなり下方にずり落ちようとした場合、保持部３０，５０が当接部４０，６０のテーパー面Ｔ１，Ｔ２に沿って摺動し壁面から離隔する方向に移動するので支持体の両端部間の短くなった長さ分を吸収する事となる。支持体の端面と保持部との接触面位置より壁面から離れた位置にテーパー面を設けているのでテーパー面を介して伸長方向に押し戻そうとする弾性力（突っ張り力）は弱まること無く働き、摩擦抵抗が生じてずり落ちを防止する効果が得られる。   According to the strut support of the present invention, as shown in FIG. 6, an excessive load is applied to the support 70, and the support is bent temporarily, and the length between both ends of the support is not bent. If the holding portion 30, 50 slides along the tapered surfaces T1, T2 of the abutment portions 40, 60 and separates from the wall surface when the holding portion 30, 50 is slid down to the length L2 in a state of being bent. In this direction, the support member absorbs the shortened length between both ends of the support. Since the tapered surface is provided at a position farther from the wall surface than the contact surface between the end surface of the support and the holding portion, the elastic force (stretching force) that pushes back in the extension direction via the tapered surface works without weakening Thus, an effect of preventing slipping due to frictional resistance is obtained.

以下、本発明の実施の形態を３例、図面を参照して詳細に説明する。 Hereinafter, three embodiments of the present invention will be described in detail with reference to the drawings.

（実施の形態１）
図５，図６は本発明の実施の形態１である突っ張り支持体の具体的実施例を示す側面図である。支持体７０は突っ張り棒で伸長方向の突っ張り力がある。その突っ張り力が保持部と当接部とを介して壁面を押す力となり摩擦抵抗が生じて突っ張り棒が壁からずり落ちる事無く圧着固定される。 (Embodiment 1)
5 and 6 are side views showing specific examples of the strut support according to the first embodiment of the present invention. The support 70 is a strut and has a strut force in the elongating direction. The striking force is a force for pushing the wall surface via the holding portion and the contact portion, and frictional resistance is generated, so that the strut rod is fixed by pressure without slipping off the wall.

図６に示す様に支持体７０に過度の荷重が加わると保持部３０，５０が当接部４０，６０のテーパー面Ｔ１，Ｔ２に沿って摺動し壁面から離隔する方向に移動するので支持体の撓みで両端部間の短くなった長さ分を吸収する事となる。支持体の端面と保持部との接触面位置より壁面から離れた位置にテーパー面を設けているのでテーパー面を介して伸長方向に押し戻そうという弾性力（突っ張り力）は弱まること無く働き、摩擦抵抗が生じてずり落ちを防止する効果が得られる。 As shown in FIG. 6, when an excessive load is applied to the support 70, the holding portions 30, 50 slide along the tapered surfaces T1, T2 of the contact portions 40, 60 and move in a direction away from the wall surface, so that the support 70, 50 is supported. The flexure of the body absorbs the shortened length between both ends. Since the taper surface is provided at a position farther from the wall surface than the contact surface position between the end surface of the support and the holding portion, the elastic force (stretching force) of pushing back in the extension direction via the taper surface works without weakening, An effect of preventing slippage due to frictional resistance is obtained.

支持体７０に伸長方向の突っ張り力がある突っ張り棚を本発明を用いて壁面間に設置しても同様に過度の荷重に対して棚のずり落ちを防止する効果がある事は明白である。 Obviously, even if a support shelf having a support force in the extension direction is installed on the support member 70 between the wall surfaces by using the present invention, there is also an effect of preventing the shelf from slipping down due to an excessive load.

（実施の形態２）
図７は本発明の実施の形態２である棚板での具体的実施例を示す側面図である。棚板８０に伸長方向の突っ張り力を発生させるコイルバネＳを保持部３０に設けている。その突っ張り力が当接部を介して壁面を押す力となり摩擦抵抗が生じて棚板が壁からずり落ちる事無く圧着固定される。 (Embodiment 2)
FIG. 7 is a side view showing a specific example of a shelf board according to the second embodiment of the present invention. The holding portion 30 is provided with a coil spring S for generating a tension force in the extension direction on the shelf plate 80. The tension force presses the wall surface via the contact portion, and frictional resistance is generated, and the shelf board is fixed by pressure bonding without slipping off the wall.

図７に示す様に棚板８０に過度の荷重が加わると保持部３０，５０が当接部４０，６０のテーパー面Ｔ１，Ｔ２に沿って摺動し壁面から離隔する方向に移動するので棚板の撓みで両端部間の短くなった長さ分を吸収する事となる。棚板の端面と保持部に設けたコイルバネとの接触位置より壁面から離れた位置にテーパー面を設けているのでテーパー面を介して伸長方向に押し戻そうという弾性力（突っ張り力）は弱まること無く働き、摩擦抵抗が生じてずり落ちを防止する効果が得られる。 As shown in FIG. 7, when an excessive load is applied to the shelf plate 80, the holding portions 30, 50 slide along the tapered surfaces T1, T2 of the abutting portions 40, 60 and move in a direction away from the wall surface. The shortened length between both ends is absorbed by the bending of the plate. Since the tapered surface is provided at a position farther from the wall surface than the contact position between the end surface of the shelf plate and the coil spring provided on the holding portion, the elastic force (stretching force) for pushing back in the extension direction via the tapered surface is weakened. It works without friction and produces the effect of preventing slippage due to frictional resistance.

棚板８０の代わりに伸長方向の突っ張り力がない棒体を本発明を用いて壁面間に設置しても同様に過度の荷重に対して棒体のずり落ちを防止する効果がある事は明白である。 It is clear that even if a bar having no tension in the extension direction is installed between the walls using the present invention instead of the shelf plate 80, the bar can be similarly prevented from slipping down due to excessive load. It is.

（実施の形態３）
図８は本発明の実施の形態３である棚板での具体的実施例を示す側面図である。棚板８０に伸長方向の突っ張り力を発生させるコイルバネＳを保持部３０に設けている。更に棚板の端面と保持部３０，５０との接触面位置より壁面に近い位置にテーパー面Ｔ３，Ｔ４を追加で設けている。テーパー面Ｔ１とテーパー面Ｔ３は同じ角度であり、テーパー面Ｔ２とテーパー面Ｔ４は同じ角度であり、テーパー面Ｔ１，Ｔ３を介して保持部３０と当接部４０が摺動自在に接し、テーパー面Ｔ２，Ｔ４を介して保持部５０と当接部６０が摺動自在に接している。コイルバネＳによる伸長方向の弾性力（突っ張り力）が当接部を介して壁面を押す力となり摩擦抵抗が生じて棚板が壁からずり落ちる事無く圧着固定される。 (Embodiment 3)
FIG. 8 is a side view showing a specific example of a shelf board according to Embodiment 3 of the present invention. The holding portion 30 is provided with a coil spring S for generating a tension force in the extension direction on the shelf plate 80. Further, tapered surfaces T3 and T4 are additionally provided at positions closer to the wall surface than the contact surfaces between the end surfaces of the shelf plates and the holding portions 30 and 50. The tapered surface T1 and the tapered surface T3 have the same angle, the tapered surface T2 and the tapered surface T4 have the same angle, and the holding portion 30 and the contact portion 40 are slidably contacted via the tapered surfaces T1 and T3. The holding portion 50 and the contact portion 60 are slidably in contact with each other via the surfaces T2 and T4. The elastic force (stretching force) in the extension direction by the coil spring S becomes a force for pressing the wall surface through the abutting portion, so that frictional resistance is generated and the shelf board is fixed by pressure without slipping off the wall.

図８に示す様に棚板８０に過度の荷重が加わると保持部３０，５０が当接部４０，６０のテーパー面Ｔ１，Ｔ３，Ｔ２，Ｔ４に沿って摺動し壁面から離隔する方向に移動するので棚板の撓みで両端部間の短くなった長さ分を吸収する事となる。棚板の端面と保持部に設けたコイルバネとの接触位置より壁面から離れた位置にテーパー面Ｔ１，Ｔ２を設けているのでテーパー面を介して伸長方向に押し戻そうという弾性力（突っ張り力）は弱まること無く働き、摩擦抵抗が生じてずり落ちを防止する効果が得られる。また追加したテーパー面Ｔ３，Ｔ４を介しても伸長方向に押し戻そうという弾性力（突っ張り力）が働くので実施の形態２より安定して壁面を押す力を伝えられる。 As shown in FIG. 8, when an excessive load is applied to the shelf plate 80, the holding portions 30, 50 slide along the tapered surfaces T1, T3, T2, T4 of the contact portions 40, 60 to separate from the wall surface. As the shelves move, they absorb the shortened length between both ends due to the bending of the shelf. Since the tapered surfaces T1 and T2 are provided at positions farther from the wall surface than the contact position between the end surface of the shelf and the coil spring provided on the holding portion, the elastic force (stretching force) of pushing back in the extension direction via the tapered surface. Works without weakening, and has the effect of preventing slippage due to frictional resistance. Also, the elastic force (stretching force) for pushing back in the extension direction acts through the added tapered surfaces T3 and T4, so that the force for pushing the wall surface can be transmitted more stably than in the second embodiment.

棚板８０の代わりに伸長方向の突っ張り力がない棒体を本発明を用いて壁面間に設置しても同様に過度の荷重に対して棒体のずり落ちを防止する効果がある事は明白である。
It is clear that even if a bar having no tension in the extension direction is installed between the walls using the present invention instead of the shelf plate 80, the bar can be similarly prevented from slipping down due to excessive load. It is.
