本発明の請求項1に記載の発明(以下、本第1発明という。)は、支持基体への軸部材固定具の取付が簡単で、短時間で行え、かつ地震などに際して軸部材が軸部材固定具から抜出さないようにした物品支持システムを提供する目的を達成するため、以下の技術的手段を採用する。   According to the first aspect of the present invention (hereinafter referred to as the first invention), it is easy to mount the shaft member fixture on the support base in a short time, and the shaft member is a shaft member in the event of an earthquake or the like. In order to achieve the object of providing an article support system which is prevented from being pulled out from the fixture, the following technical means are adopted.

すなわち、中空部で隔てられた前壁と後壁とを有する支持基体と、該支持基体の前壁に形成された挿入口に前方から差込んで前後移動不能に、かつ前後軸心周りに回転不能に該支持基体に固定され、前方から軸部材の後端部が差込まれる軸孔が形成された本体を備える軸部材固定具と、該軸部材固定具に形成された軸孔に後端部が係脱可能に挿入される軸部材とを備えた物品支持システムであって上記軸部材固定具は、上記本体の正面から見た輪郭が上記前壁に透設された挿通口に前後軸心周りに回転不能に挿通できる形状に形成される一方、上記挿通口に該本体が上記後壁に受止められる位置まで挿入された状態で、該本体から上記中空部内で上記前壁を受止める位置に出没するストッパと、該ストッパを進出付勢するストッパスプリングとを備えることを特徴とする。 That is, a support base having a front wall and a rear wall separated by a hollow portion, and inserted into the insertion port formed in the front wall of the support base from the front so as not to move back and forth and rotate around the front and rear axis A shaft member fixture having a main body formed with a shaft hole in which the rear end portion of the shaft member is inserted from the front, and the rear end of the shaft hole formed in the shaft member fixture. The shaft supporting member is detachably inserted into the article supporting system, wherein the shaft member fixing tool is arranged in front and rear at an insertion port having a contour as seen from the front of the main body. The front wall is received in the hollow portion from the main body while the main body is inserted into the insertion port to a position where it can be received by the rear wall. Stopper that appears and stops at the stop position, and stopper spring that moves the stopper forward Characterized in that it comprises and.

この構成によれば、軸部材固定具は支持基体の挿入口に差込むという簡単で、時間の掛らない作業で支持基体に前後移動不能に、かつ前後軸心周りに回転不能に組付けることができる。   According to this configuration, the shaft member fixing tool is simply inserted into the insertion hole of the support base, and can be assembled to the support base so as not to move back and forth and to rotate around the front and rear axes in a time-consuming operation. Can do.

又、軸部材固定具の軸孔に挿入させた軸部材の後端部を該軸部材固定具に係合することにより、地震などに際して支持基体及びこれに固定された軸部材固定具に軸部材が連動するので、軸部材が軸孔から抜出すおそれがなくなる。   Further, by engaging the rear end portion of the shaft member inserted into the shaft hole of the shaft member fixing tool with the shaft member fixing tool, the shaft member is fixed to the support base and the shaft member fixing tool fixed thereto in the event of an earthquake or the like. Are interlocked, so there is no possibility that the shaft member is pulled out from the shaft hole.

更に、軸部材と軸部材支持具との係合を解除すれば、簡単に軸部材を軸孔から抜取ることができるので、軸部材の交換作業や取付位置の変更作業の作業性が損なわれることはほとんどない。   Furthermore, if the engagement between the shaft member and the shaft member support is released, the shaft member can be easily removed from the shaft hole, so the workability of the shaft member replacement work and the mounting position change work is impaired. There is hardly anything.

なお、上記支持基材は前後に適当な間隔を置いた前壁と後壁とを備えるものであればよく、例えば角パイプ、丸パイプ、溝型材、C型材、H型材、I型材などからなる支持基体や、前後2重壁を有するパネルなどが含まれる。   Note that the supporting base material only needs to have a front wall and a rear wall that are spaced apart from each other at an appropriate distance. A support base, a panel having double front and back walls, and the like are included.

軸部材を上側に立ち上がるように支持する支持基材を用いる場合には、前を上と読み替え、後を下と読み替え、上を前後左右のいずれかに読み替え、下を上と反対側の前後左右のいずれかに読みかえればよい。   When using a support base that supports the shaft member so that it rises upward, read the front as up, read the back as down, read the top as either front, back, left, or right, and read the bottom as front, back, left, or right. You can replace it with either of these.

本第1発明の更に詳細な説明は、本発明の請求項以下の詳細な説明と重複するので、ここでは省略することにする。 Since the further detailed description of the first invention overlaps with the detailed description of claim 6 of the present invention, it will be omitted here.

次に、本発明の請求項2に記載の発明は、地震などに際して軸部材が抜出さないようにした物品支持システムを提供する目的を達成するため、以下の技術的手段を採用する。 Next, inventions of claim 2 of the present invention, in order to achieve the object of providing an article support system to prevent the shaft member is withdrawn during an earthquake, adopts the following technical means.

即ち、上記軸部材固定具の上記軸孔の後部に、上記軸部材の後端部に形成された下向きに凹入する係合凹部が形脱される係止部が設けられ、上記軸部材の自重による軸孔の前端を中心とする回転力により上記係止部に上記軸部材の係合凹部を係合させ、この回転力に抗して上記軸部材の前端を上向きに回転させることにより上記軸部材固定具の係止部から上記軸部材の係合凹部を離脱させることを特徴とする。That is, a locking portion is formed at the rear portion of the shaft hole of the shaft member fixing tool, and an engagement recess formed in the rear end portion of the shaft member to be recessed downward is removed. The engaging recess of the shaft member is engaged with the locking portion by a rotational force centered on the front end of the shaft hole due to its own weight, and the front end of the shaft member is rotated upward against the rotational force. The engaging recess of the shaft member is disengaged from the locking portion of the shaft member fixing tool.

これによれば、軸部材の後端部を軸孔に差込んで軸部材を手放すと、上記係止部に係合凹部が係合され、軸部材の後端部の軸孔からの脱出を防止できる一方、軸部材の前端を上に持上げると上記係止部から係合凹部が離脱し、簡単に軸部材を軸孔から抜取ることができる。   According to this, when the rear end portion of the shaft member is inserted into the shaft hole and the shaft member is released, the engagement recess is engaged with the locking portion, and the rear end portion of the shaft member is prevented from escaping from the shaft hole. On the other hand, when the front end of the shaft member is lifted up, the engaging recess is detached from the locking portion, and the shaft member can be easily removed from the shaft hole.

ところで、上記の構成の発明においては、本発明の請求項に記載の発明のように、上記軸孔底部に、該軸孔に挿入された上記軸部材の後端部を上向きに付勢して上記係止部に係合凹部を係合させる押えバネが設けられることを特徴とする構成を採用することができる。 By the way, in the invention with the above configuration, as in the invention according to claim 3 of the present invention, the rear end portion of the shaft member inserted into the shaft hole is biased upward at the bottom portion of the shaft hole. Thus, it is possible to employ a configuration in which a presser spring that engages the engaging recess with the engaging portion is provided.

この構成によれば、押えバネにより軸部材の係合凹部と軸孔の係止部との係合が保持されるので、軸部材の脱出が一層確実に防止できる一方、上記押えバネに抗して軸部材の前端を上に持上げると上記係止部から係合凹部が離脱し、簡単に軸部材を軸孔から抜取ることができる。   According to this configuration, since the engagement between the engaging recess of the shaft member and the locking portion of the shaft hole is held by the presser spring, the escape of the shaft member can be prevented more reliably, while resisting the presser spring. When the front end of the shaft member is lifted up, the engaging recess is detached from the locking portion, and the shaft member can be easily removed from the shaft hole.

又、この構成によれば、上記係止部と係合凹部との係合が上記押えバネの付勢力により確保されるので、中空部で隔てられた上壁と下壁とを備える支持基体に軸部材を該支持基体の上側に立上げるために用いる軸部材固定具にも適用することができる。この場合には、本明細書の前を上に、後を下に、上を前後左右のいずれか一つに、下をその反対側にそれぞれ読み替えればよい。   Further, according to this configuration, since the engagement between the locking portion and the engagement recess is ensured by the biasing force of the presser spring, the support base including the upper wall and the lower wall separated by the hollow portion is provided. The present invention can also be applied to a shaft member fixing tool used for raising the shaft member above the support base. In this case, the front of the present specification may be read as the top, the back as the bottom, the top as one of the front, back, left and right, and the bottom as the opposite side.

なお、中空部で隔てられた上壁と下壁とを備える支持基体に軸部材を懸垂させるために用いる軸部材支持具に上記構成を適用することは、横揺れ時に上記係止部と係合凹部との係合が解除され、軸部材が落下するおそれがあるので、好ましくない。   Note that applying the above configuration to the shaft member support used for suspending the shaft member on a support base having an upper wall and a lower wall separated by a hollow portion engages with the locking portion when rolling. This is not preferable because the engagement with the recess is released and the shaft member may fall.

ところで、上記構成の発明においては、本発明の請求項に記載の発明のように、上記係合凹部が上記後端部の基端面から該軸部材の軸方向に凹入させた割り溝の奥部に形成され、上記係止部がこの割り溝に突入させるピンからなることを特徴とする構成を採用することができる。 By the way, in the invention of the above configuration, as in the invention according to claim 4 of the present invention, the engagement recess is formed of a split groove that is recessed from the base end surface of the rear end portion in the axial direction of the shaft member. It is possible to adopt a configuration characterized in that it is formed in the inner part and the locking part is made of a pin that enters into the split groove.

この構成によれば、軸部材の振動により係止部と係合凹部との係合が甘くなっても、係合凹部が大きく係止部から離隔することが防止され、振動の沈静により係止部と係合凹部との係合が回復され易くなるので、軸部材が勝手に抜出すことが一層確実に防止できる。   According to this configuration, even if the engagement between the locking portion and the engagement recess is loosened by the vibration of the shaft member, the engagement recess is prevented from being largely separated from the locking portion. Since the engagement between the portion and the engagement recess is easily recovered, the shaft member can be more reliably prevented from being pulled out without permission.

、本発明の請求項に記載の発明のように、上記後端部の下面を、上記軸部材の前端を上向きに所定の角度だけ回転させた時にほぼ水平になるように傾斜させてあることを特徴とする構成を採用することができる。 Further , as in the invention described in claim 5 of the present invention, the lower surface of the rear end portion is inclined so as to be substantially horizontal when the front end of the shaft member is rotated upward by a predetermined angle. The structure characterized by this can be adopted.

この構成によれば、軸部材固定具の軸孔の断面形状を前後に一様にすることができ、軸部材固定具を安価にすることができる。   According to this configuration, the cross-sectional shape of the shaft hole of the shaft member fixture can be made uniform in the front-rear direction, and the shaft member fixture can be made inexpensive.

次に、本発明の請求項に記載の発明(以下、本第2発明という。)は、支持基体への取付けが簡単に、かつ短時間で行えるようにした軸部材固定具を提供する目的を達成するため、以下の技術的手段を採用する。 Next, an invention according to claim 6 of the present invention (hereinafter referred to as the second invention) provides a shaft member fixture that can be easily and quickly mounted on a support base. In order to achieve the above, the following technical means are adopted.

即ち、中空部で隔てられた前壁と後壁とを有する支持基体に固定され、前方から軸部材の後端部が差込まれる軸孔が形成されている本体を備える軸部材固定具において、上記本体の正面から見た輪郭が上記支持基体の前壁に透設された挿通口に前後軸心周りに回転不能に挿通される形状に形成される一方、上記挿通口に該本体が上記後壁に受止められる位置まで挿入された状態で、該本体から上記中空部内で上記前壁を受止める位置に出没するストッパと、該ストッパを進出付勢するストッパスプリングとを備えることを特徴とする技術的手段を採用する。   That is, in a shaft member fixture that includes a body that is fixed to a support base having a front wall and a rear wall separated by a hollow portion, and has a shaft hole into which a rear end portion of the shaft member is inserted from the front. The outline of the main body viewed from the front is formed into a shape that is inserted in a through-hole formed in the front wall of the support base so as not to rotate around the front-rear axis. A stopper that protrudes and retracts to a position for receiving the front wall in the hollow portion from the main body in a state of being inserted to a position that can be received by a wall, and a stopper spring that advances and biases the stopper. Adopt technical means.

この構成によれば、例えば手指やドライバの爪先によって上記ストッパスプリングに抗して上記ストッパを上記本体内に押し込めた状態で、該本体を支持基体の前方から、該支持基体の前壁に形成された挿入口に、該本体が上記支持基体の後壁に受止められるまで押し込めると、上記ストッパが上記支持基体の中空部に突出して、該支持基体の前壁の内面を受止める。これにより、上記本体は、上記挿入口の口縁により前後軸心周りの回転を不能にされた状態で、上記支持基体の後壁と前壁とにより前後方向に移動不能に該支持基体に組付けられる。   According to this configuration, for example, the main body is formed on the front wall of the support base from the front of the support base in a state where the stopper is pushed into the main body against the stopper spring by a finger or a toe of a driver. When the main body is pushed into the insertion port until it is received by the rear wall of the support base, the stopper protrudes into the hollow portion of the support base and receives the inner surface of the front wall of the support base. As a result, the main body is assembled to the support base so that it cannot be moved in the front-rear direction by the rear wall and the front wall of the support base in a state in which the rotation around the front-rear axis is disabled by the edge of the insertion port. Attached.

すなわち、上記ストッパを上記本体内に押し込めた状態で、上記本体をその後面が上記支持基体の後壁に受止められるまで挿入口に押し込めるというすこぶる簡単な作業で、短時間で、上記本体を支持基体に、上記軸孔の上下左右方向の位置及び前後軸心周りの角度が正確に割出された状態に組付けることができる。   That is, in a state where the stopper is pushed into the main body, the main body is supported in a short time by a simple operation of pushing the main body into the insertion port until the rear surface is received by the rear wall of the support base. The base body can be assembled in a state in which the position of the shaft hole in the vertical and horizontal directions and the angle around the longitudinal axis are accurately determined.

ところで、本第2発明においては、必要に応じて、上記の構成に加えて、本発明の請求項に記載の発明のように、上記本体の後面から上記支持基体の後壁に透設された位置決め孔に内接する位置決め突起が突設されていることを特徴とする構成を採用することができる。 By the way, in the second aspect of the invention, in addition to the above-described configuration, as in the case of the seventh aspect of the present invention, the rear surface of the main body is transparently provided on the rear wall of the support base as necessary. It is possible to adopt a configuration characterized in that a positioning projection inscribed in the positioning hole is provided.

この構成を採用すれば、本体を支持基体の後内面に受止められるまで支持基体に差込み、上記位置決め突起を位置決め孔に突入して内接させることにより、上記本体を上記挿通口と上記位置決め孔との2箇所で位置決めし、軸孔の位置及び方向が一層正確に割出された状態で上記支持基体に上記本体を組付けることができる。   If this configuration is adopted, the main body is inserted into the support base until it is received by the rear inner surface of the support base, and the positioning protrusion is inserted into the positioning hole to be inscribed therein, whereby the main body is inserted into the insertion hole and the positioning hole. The main body can be assembled to the support base in a state where the position and direction of the shaft hole are indexed more accurately.

又、本第2発明においては、必要に応じて、本発明の請求項に記載の発明のように、上記ストッパの先端面の少なくとも後部が斜め後向きの傾斜面又は斜め後ろ向きに突な湾曲面に形成されていることを特徴とする構成を採用することができる。 In the second aspect of the present invention, as required, as in the eighth aspect of the present invention, at least the rear portion of the front end surface of the stopper is an inclined rearward inclined surface or a curved surface protruding obliquely rearward. The structure characterized by being formed in can be adopted.

この構成によれば、上記本体を上記挿通口に押し込む際に、ストッパの先端面の後部が挿通口の口縁に押し当てられると、その傾斜面又は湾曲面のカム作用により、ストッパが上記挿入口の口縁に押されて本体内に押し込まれるので、上記ストッパを手指やドライバで押し込む必要がなくなり、一層簡単に、又、一層短時間で上記軸部材固定具を上記支持基体に組付けることができる。   According to this configuration, when the rear portion of the front end surface of the stopper is pressed against the edge of the insertion port when the main body is pushed into the insertion port, the stopper is inserted by the cam action of the inclined surface or the curved surface. Since it is pushed into the main body by being pushed by the lip of the mouth, it is not necessary to push the stopper with a finger or a screwdriver, and the shaft member fixing tool can be assembled to the support base more easily and in a shorter time. Can do.

さらに、この構成において、本発明の請求項に記載の発明のように、上記本体内から該本体の前方に出没可能に設けられたステムと、上記本体内で該ステムを進出付勢するセットスプリングが設けられ、上記ストッパがこのステムに連動して前後に進退可能に上記本体に支持されていることを特徴とする構成を採用することができる。 Further, in this configuration, as in the ninth aspect of the present invention, a stem provided so as to be able to protrude and retract in front of the main body from within the main body, and a set for advancing and biasing the stem within the main body It is possible to employ a configuration in which a spring is provided and the stopper is supported by the main body so as to be able to move forward and backward in conjunction with the stem.

この構成によれば、ストッパ及びステムがセットスプリングにより進出付勢された状態で上記本体が上記挿入口に挿入され、上記本体が上記支持基材の後壁に受止められた後、上記セットスプリングに抗して上記ステムを上記本体の前面まで押し込むことにより、ストッパがそれ自体のカム作用で挿入口を潜り抜け、上記中空部内で上記前壁を受止める位置に突出する。この後、ステムを放すと、セットスプリングの力でストッパが前壁に押圧され、上記本体が前後にがたつくことが確実に防止される。又、前壁と後壁との間隔が異なる複数種類の支持基材に共通の軸部材固定具を用いることができる。   According to this configuration, after the stopper and the stem are advanced and urged by the set spring, the main body is inserted into the insertion port, and the main body is received by the rear wall of the support base. When the stem is pushed to the front surface of the main body against this, the stopper penetrates through the insertion port by its own cam action and protrudes to a position where the front wall is received in the hollow portion. After that, when the stem is released, the stopper is pressed against the front wall by the force of the set spring, and the main body is reliably prevented from shaking back and forth. Moreover, a common shaft member fixing tool can be used for a plurality of types of support bases having different intervals between the front wall and the rear wall.

加えて、本第2発明においては、本発明の請求項10に記載の発明のように、上記支持基体の前側で上記ストッパに連動して本体内から本体外に出没可能に設けられた解除操作部を備えていることを特徴とする構成を採用することができる。 In addition, in the second aspect of the present invention, as in the tenth aspect of the present invention, a release operation is provided on the front side of the support base so as to be able to protrude from inside the main body to outside the main body in conjunction with the stopper. The structure characterized by providing the part can be adopted.

この構成によれば、上記本体を支持基体に組付けた後、解除操作部を例えばドライバの爪先で上記スプリングに抗して本体内に押し込めて上記ストッパを本体内に退入させ、本体を支持基体から引き抜くことができるようになる。   According to this structure, after assembling the main body to the support base, the release operation portion is pushed into the main body against the spring with the tip of a driver, for example, and the stopper is retracted into the main body to support the main body. It can be pulled out from the substrate.

以上に説明したように、本発明によれば、軸部材固定具を支持基体に差込むだけで支持基体に前後移動不能に、かつ前後軸心周りに回転不能に固定でき、又、支持基体に固定された軸部材支持具に軸部材を差込むだけで、軸部材を地震などに際して軸部材固定具から抜出さないように軸部材固定具に支持させることができるという効果を得ることができる。 As described above, according to the present invention , the shaft member fixing tool can be fixed to the support base so as not to move back and forth and to be unrotatable around the front and rear axes simply by being inserted into the support base. It is possible to obtain an effect that the shaft member can be supported by the shaft member fixing tool so as not to be pulled out from the shaft member fixing tool in the event of an earthquake or the like simply by inserting the shaft member into the fixed shaft member supporting tool.

又、本発明によれば、上記ストッパを上記本体内に押し込めながら、該本体を支持基体の挿入口に、該本体が支持基体の後内面に受止められるまで押し込めるという簡単な作業で、短時間で、本体を支持基体に組付けることができるという効果を得ることができる。 In addition, according to the present invention , while the stopper is pushed into the main body, the main body is pushed into the insertion opening of the support base until the main body is received by the rear inner surface of the support base. Thus, the effect that the main body can be assembled to the support base can be obtained.

更に、本発明によれば、支持基体に支持させた軸部材固定具の軸孔に軸部材を差込んで手放すだけで簡単に、短時間で軸部材固定具に軸部材を組付けることができるという効果、軸部材の係合凹部と軸孔に設けた係止部との係合により軸部材が勝手に軸孔から抜けることを防止できるという効果、及び軸部材の前端部を上に持上げると簡単に軸部材を軸部材固定具から抜取ることができるという効果などを得ることができる。 Furthermore, according to the present invention , the shaft member can be assembled to the shaft member fixture in a short time simply by inserting the shaft member into the shaft hole of the shaft member fixture supported by the support base and releasing the shaft member. The effect that the shaft member can be prevented from coming out of the shaft hole by the engagement between the engaging recess of the shaft member and the engaging portion provided in the shaft hole, and the front end portion of the shaft member is lifted up. The effect that the shaft member can be easily removed from the shaft member fixture can be obtained.

加えて、本発明によれば、支持基体に支持させた軸部材固定具の軸孔に軸部材を差込んで手放すだけで簡単に、短時間で軸部材固定具に軸部材を組付けることができるという効果、軸部材の係合凹部と軸孔に設けた係止部との係合により軸部材が勝手に軸孔から抜けることを防止できるという効果、及び軸部材の前端部を上に持上げると簡単に軸部材を軸部材固定具から抜取ることができるという効果などを得ることができる。 In addition, according to the present invention , the shaft member can be assembled to the shaft member fixture in a short time simply by inserting the shaft member into the shaft hole of the shaft member fixture supported by the support base and releasing it.

上記支持基体2は正方形角パイプで構成している。又、該支持基体2の前壁21に透設される挿入口22は非円形であればよく、例えば楕円形、小判形、正方形などに形成してもよいが、ここでは、4隅を小さく丸めた縦長の長方形に形成してあり、上記本体11の前から見た輪郭はこの挿入口22よりも僅かに小さい相似の4隅を小さく丸めた縦長の長方形に形成している。   The support base 2 is composed of a square square pipe. Further, the insertion port 22 formed through the front wall 21 of the support base 2 may be non-circular, and may be formed in an oval shape, an oval shape, a square shape, or the like. It is formed in a rounded vertically long rectangle, and the outline seen from the front of the main body 11 is formed in a vertically long rectangle having four similar corners slightly smaller than the insertion opening 22 rounded down.

なお、前から見た本体11の輪郭と挿入口22との間には僅かな隙間ができるが、この隙間は本体11を差込む作業を容易にするためのものであり、軸部材固定具1のぐらつき、特に横揺れを小さくするためにはできるだけ小さい方が好ましい。   A slight gap is formed between the outline of the main body 11 and the insertion port 22 as viewed from the front. This gap is for facilitating the work of inserting the main body 11, and the shaft member fixture 1. In order to reduce the wobbling, particularly the roll, it is preferable to make it as small as possible.

図1に示すように、上記支持基体2の後壁23には上記挿入口22の正面投影内に円形の位置決め孔24が透設され、上記本体11には、後面111からこの位置決め孔24に内接する位置決め突起112が突設されている。   As shown in FIG. 1, a circular positioning hole 24 is formed in the rear wall 23 of the support base 2 in the front projection of the insertion port 22, and the main body 11 has a rear surface 111 through the positioning hole 24. A positioning protrusion 112 is provided so as to be inscribed.

この位置決め突起112は上記本体11の上下方向の中心よりも下方に偏心させてあり、この位置決め突起112の中心を通って該本体11を前後に貫通する軸孔12が形成される。   The positioning projection 112 is decentered downward from the vertical center of the main body 11, and a shaft hole 12 is formed through the center of the positioning projection 112 and penetrating the main body 11 in the front-rear direction.

この軸孔12の断面形状は、特に限定されないが、例えば棚受軸からなる軸部材3の後端部31の断面形状に対応する形状が採用され、ここでは、縦長の長方形に形成されている。   Although the cross-sectional shape of the shaft hole 12 is not particularly limited, for example, a shape corresponding to the cross-sectional shape of the rear end portion 31 of the shaft member 3 including a shelf receiving shaft is adopted, and here, the shaft hole 12 is formed in a vertically long rectangle. .

上記本体11の上部には、前後方向に直交する方向(ここでは上方)に該本体11内から本体11外に出没可能に該本体11に支持され、上記支持基体2の中空部25に突入して該支持基体2の前壁21の内面26を受止めるストッパ13と、該ストッパ13を進出付勢するストッパスプリング14とが設けられる。   An upper portion of the main body 11 is supported by the main body 11 so as to be able to protrude from the main body 11 to the outside of the main body 11 in a direction perpendicular to the front-rear direction (here, upward), and enters the hollow portion 25 of the support base 2. A stopper 13 for receiving the inner surface 26 of the front wall 21 of the support base 2 and a stopper spring 14 for advancing and biasing the stopper 13 are provided.

又、このストッパ13と一体に形成され、上記前壁21の前方で該ストッパ13に連動して上記本体11内から本体11外に出没する解除操作部15が設けられ、上記ストッパ13と解除操作部15の間には上記支持基体2の挿入口22の上縁が嵌り込む摺り割溝16が形成されている。   Further, a release operation portion 15 is formed integrally with the stopper 13 and moves in and out of the main body 11 from the inside of the main body 11 in conjunction with the stopper 13 in front of the front wall 21. Between the portions 15, a slit groove 16 into which the upper edge of the insertion port 22 of the support base 2 is fitted is formed.

上記ストッパ13の先端面131は斜め後に突な腕曲面に形成されており、位置決め突起112を後にして、本体11を挿入口22に押し込み、該挿入口22の上縁に上記ストッパ13が受止められた後、更に本体11を上記支持基体2に押し込むと、上記挿入口22の上縁がストッパ13を本体11内に押し込む。位置決め突起112が位置決め孔24に突入してから位置決め孔24に内接して、上記本体11が後壁23に受止められると、ほぼ同時に或いはそれよりも一瞬早くストッパ13が挿入口22の上縁を潜り抜けて上記支持基体2の中空部25に突入し、該支持基体2の前壁21の内面26を受止める。   The front end surface 131 of the stopper 13 is formed as an arm curved surface protruding obliquely, the positioning projection 112 is left behind, the main body 11 is pushed into the insertion port 22, and the stopper 13 is received by the upper edge of the insertion port 22. When the main body 11 is further pushed into the support base 2 after being stopped, the upper edge of the insertion port 22 pushes the stopper 13 into the main body 11. When the positioning projection 112 enters the positioning hole 24 and then contacts the positioning hole 24 and the main body 11 is received by the rear wall 23, the stopper 13 is almost simultaneously or a moment earlier than the upper edge of the insertion port 22. Through the hollow portion 25 of the support base 2 to receive the inner surface 26 of the front wall 21 of the support base 2.

このように、軸部材固定具1を位置決め突起112を後にして上記支持基体2の前方から挿入口22に差込み、位置決め突起112を位置決め孔25に突入させて内接するまで本体11を差込むという一連の、いわばワンタッチとも言える簡単な作業により、短時間で軸部材固定具1を支持基体2に、前後移動不能に、かつ前後軸心周りに回転不能に組付けることができる。   In this manner, the shaft member fixing tool 1 is inserted into the insertion port 22 from the front of the support base 2 after the positioning protrusion 112, and the main body 11 is inserted until the positioning protrusion 112 is inserted into the positioning hole 25 and inscribed. By a series of simple operations that can be said to be one-touch, the shaft member fixing tool 1 can be assembled to the support base 2 in a short time so as not to move back and forth and to rotate around the front and rear axis.

なお、この軸部材固定具1は、これが支持する軸部材3の荷重による前下がりに対応させるために、上記軸孔12の軸線がたとえば約1°前上がりに傾斜するように上記支持基体2に組付けられる。   The shaft member fixing tool 1 is attached to the support base 2 so that the axis of the shaft hole 12 is inclined upward by about 1 °, for example, in order to correspond to the front lowering due to the load of the shaft member 3 supported by the shaft member fixing tool 1. It is assembled.

又、軸部材3としては棚受部材を用いているが、この他に例えばハンガーパイプを軸部材3として用いてもよい。   Moreover, although the shelf receiving member is used as the shaft member 3, for example, a hanger pipe may be used as the shaft member 3.

ところで、上記本体11の軸孔12内の後部には、左右横軸のピンからなる係止部17が設けられ、前方からこの軸孔12に挿入される軸部材3の後端部31には、該後端部31の基端面32から該軸部材3の軸方向に凹入させた割り溝33と、この割り溝33の奥端部、すなわち前端部に連続して下方に凹入させた係合凹部34とが形成されている。   By the way, the rear part in the shaft hole 12 of the main body 11 is provided with a locking part 17 made of a pin on the left and right horizontal axis, and on the rear end part 31 of the shaft member 3 inserted into the shaft hole 12 from the front. The groove 33 is recessed in the axial direction of the shaft member 3 from the base end face 32 of the rear end portion 31, and the lower end of the groove 33, that is, the front end is continuously recessed downward. An engaging recess 34 is formed.

上記本体11の前方から上記軸部材3の後端部31を上記軸孔12に差込むと、上記係止部17が上記割り溝33に突入する。この後、上記係止部17に上記割り溝33の奥端(前端)が受止められるまで上記軸部材3の後端部31を軸孔12に差込んでから該軸部材3を手放すと、該軸部材3の自重により、上記軸孔12の前端下縁を中心にして該軸部材3の基端が上に、先端が下に回転し、上記係合凹部34が上記係止部17に噛合う。   When the rear end portion 31 of the shaft member 3 is inserted into the shaft hole 12 from the front of the main body 11, the locking portion 17 enters the split groove 33. Thereafter, when the rear end portion 31 of the shaft member 3 is inserted into the shaft hole 12 until the rear end (front end) of the split groove 33 is received by the locking portion 17, the shaft member 3 is released. Due to the weight of the shaft member 3, the base end of the shaft member 3 is rotated upward and the distal end is rotated downward around the lower edge of the front end of the shaft hole 12. Mesh.

上記軸孔12の下面には、角溝18が凹設され、この角溝18に、該角溝18から上記軸孔12内に弓なりに張り出す板バネからなる押えバネ19が配置され、この押えバネ19により軸部材3の後端部31を上向きに付勢することにより、上記係合凹部34が確実に係止部17に噛合い、例えば地震などの振動によりこれら係止部17と係合凹部34との噛合いが解消されないようににしている。   A square groove 18 is recessed in the lower surface of the shaft hole 12, and a presser spring 19 made of a plate spring projecting from the square groove 18 into the shaft hole 12 is disposed in the square groove 18. By urging the rear end portion 31 of the shaft member 3 upward by the presser spring 19, the engagement recess 34 is surely engaged with the engagement portion 17, and the engagement portion 17 is engaged with the engagement portion 17 by vibration such as an earthquake. The engagement with the mating recess 34 is prevented from being eliminated.

上記軸部材3の後端部31の下面35は、作業者が押えバネ19と上記軸部材3の自重に抗して上記軸部材3の前端を所定の角度まで持上げると水平になるように、該軸部材31の軸線に対して後上がりに緩く傾斜させてある。   The lower surface 35 of the rear end portion 31 of the shaft member 3 is horizontal when an operator lifts the front end of the shaft member 3 to a predetermined angle against the weight of the presser spring 19 and the shaft member 3. The shaft member 31 is gently inclined rearwardly with respect to the axis of the shaft member 31.

これにより、上記軸孔12の形状を単純な長方形角孔に形成することができ、上記本体11を安価に形成できるようにしている。   Thereby, the shape of the shaft hole 12 can be formed into a simple rectangular square hole, and the main body 11 can be formed at low cost.

上記押えバネ19と軸部材3の自重に抗して該軸部材3の前端が所定の角度持上げられると、係止部17から係合凹部34が離脱し、上記軸部材3を自由に軸孔12から抜取ることができ、簡単に軸部材3を交換したり、軸部材3を高さの異なる軸部材固定具1に付替えたりすることができる。   When the front end of the shaft member 3 is lifted by a predetermined angle against the weight of the presser spring 19 and the shaft member 3, the engagement recess 34 is detached from the locking portion 17, and the shaft member 3 can be freely moved into the shaft hole. The shaft member 3 can be easily replaced, or the shaft member 3 can be replaced with the shaft member fixture 1 having a different height.

ところで、図3はこれらの軸部材固定具1、支持基体2及び軸部材3を用いる展示棚支持システムの分解斜視図である。   Incidentally, FIG. 3 is an exploded perspective view of the display shelf support system using these shaft member fixture 1, the support base 2, and the shaft member 3.

図3に示すように、この展示棚支持構造は、特殊形鋼材からなる柱状のベース4の前部に上記支持基体2を嵌め込んで固定し、該ベース4の左右両面に裏地骨材5を固定し、上述のように支持基体2に軸部材固定具1を組付ける。   As shown in FIG. 3, this display shelf support structure is configured such that the support base 2 is fitted and fixed to the front portion of a columnar base 4 made of a special shaped steel material, and a lining aggregate 5 is attached to both left and right sides of the base 4.

上記支持基体2には上下多段に挿入口22が形成され、その中から任意に選択された少なくとも1口の挿入口22に軸部材固定具1が組付けられる。   Insertion ports 22 are formed in the support base 2 in multiple upper and lower stages, and the shaft member fixture 1 is assembled to at least one insertion port 22 arbitrarily selected therefrom.

例えば誤った位置に組付けられた軸部材固定具1を正しい位置に付け直す場合には、上記解除操作部15を例えばドライバの先で押えて本体11内に退入させることにより上記ストッパ13を本体11内に退入させ、この後、該ストッパ13を本体11内に保持しながら本体11を挿入口22から前方に抜取り、正しい挿入口22に差込めばよい。   For example, when reattaching the shaft member fixing tool 1 assembled at an incorrect position to the correct position, the stopper 13 is moved into the main body 11 by pushing the release operation portion 15 with a tip of a driver, for example. The main body 11 may be retracted into the main body 11, and then the main body 11 may be removed from the insertion port 22 while being held in the main body 11 and inserted into the correct insertion port 22.

図1から図3に示すように、上記本体11には、必要に応じて、その前面113から上記軸孔12を中心にして前方に突出する飾り突起114が形成されている。   As shown in FIGS. 1 to 3, the main body 11 is formed with a decorative projection 114 that protrudes forward from the front surface 113 around the shaft hole 12 as necessary.

軸部材固定具1を所定の挿入口22に組付けた後、支持基体2の前面を覆うパネル6を例えばビス止め、溶接などにより左右の裏地骨材5に固定する。   After assembling the shaft member fixture 1 to the predetermined insertion port 22, the panel 6 covering the front surface of the support base 2 is fixed to the left and right lining aggregates 5 by, for example, screwing or welding.

図3に示すように、このパネル6の上記軸孔12に対応する位置には上記軸部材3の基端部31を挿通する分銅形の開口部61が形成され、裏地骨材5に固定されたパネル6の開口部61から上記本体11の軸孔12に軸部材3の後端部31を抜差しできるようにする。   As shown in FIG. 3, a weight-shaped opening 61 through which the base end portion 31 of the shaft member 3 is inserted is formed at a position corresponding to the shaft hole 12 of the panel 6, and is fixed to the lining aggregate 5. The rear end portion 31 of the shaft member 3 can be inserted into and removed from the shaft hole 12 of the main body 11 through the opening 61 of the panel 6.

図2と図3に示すように、上記本体11の左右両側面には、上記軸孔12と同じ高さに、前後方向の全長にわたってカバー差込み溝115が形成され、上記パネル6にもこれらのカバー差込溝115に対応して、上記開口部61の左右両側に連続する切欠き62が形成される。   As shown in FIGS. 2 and 3, cover insertion grooves 115 are formed on the left and right side surfaces of the main body 11 at the same height as the shaft hole 12 over the entire length in the front-rear direction. Corresponding to the cover insertion groove 115, continuous notches 62 are formed on the left and right sides of the opening 61.

上記パネル6の左右両側には上記下地骨材5に固定される例えば石膏ボード、ベニヤ板などからなる下地壁板7が配置され、必要に応じて、上記パネル6及び下地壁板7の前面を図示しない壁紙、クロス、合成樹脂パネル、ガラスパネル、ミラーなどの壁仕上材で仕上る。   A base wall plate 7 made of, for example, a gypsum board or a plywood plate, which is fixed to the base aggregate 5 is disposed on both the left and right sides of the panel 6, and the front surfaces of the panel 6 and the base wall plate 7 are illustrated as necessary. Finish with wall finishing materials such as wallpaper, cloth, synthetic resin panels, glass panels, mirrors.

この後、パネル6の開口部61及び切欠き62に対応する壁仕上材の部分を刳り抜き、見栄えを良くするために、パネル6の各開口部61に孔カバー8を取付ける。   Thereafter, the hole cover 8 is attached to each opening 61 of the panel 6 in order to cut out portions of the wall finishing material corresponding to the opening 61 and the notch 62 of the panel 6 and improve the appearance.

この孔カバー8は平板状のカバー本体81と、その後面の左右両側部から後方に突出させた1対の取付ピン82とを備え、上記カバー本体81の中央部に上記軸部材3の断面形状に対応する形状の切抜孔83が形成され、上記取付ピン82をパネル6の切欠き62及び上記本体11の左右のカバー差込溝115に圧入することにより孔カバー8がパネル6に組付けられる。   The hole cover 8 includes a flat cover body 81 and a pair of mounting pins 82 protruding rearward from the left and right side portions of the rear surface, and a cross-sectional shape of the shaft member 3 at the center of the cover body 81. The hole cover 8 is assembled to the panel 6 by press-fitting the mounting pin 82 into the notch 62 of the panel 6 and the left and right cover insertion grooves 115 of the main body 11. .

もっとも、上記取付ピン82に代えて、カバー本体81の左右両側に挿通される例えば平皿小ねじを上記カバー差込溝115に螺挿するようにしてもよい。   However, instead of the mounting pin 82, for example, flat countersunk screws inserted through the left and right sides of the cover body 81 may be screwed into the cover insertion groove 115.

この後、所定の高さの軸部材固定具1に軸部材3を組付け、軸部材3を配置しない位置の孔カバー8には、磁気吸着により該孔カバー8のカバー本体81を前から全面的に覆う飾りカバー9を取付ける。   Thereafter, the shaft member 3 is assembled to the shaft member fixture 1 having a predetermined height, and the hole cover 8 at a position where the shaft member 3 is not disposed is placed on the entire surface of the cover body 81 of the hole cover 8 from the front by magnetic adsorption. A decorative cover 9 is attached.

孔カバー8に飾りカバー9を磁気吸着させるためには、孔カバー8と飾りカバー9との一方又は両方に磁石を担持させ、その他方を磁性体で構成すればよい。ここで磁石とは金属製の磁石のほかに強磁性体粉末を配合したゴムを含む高分子化合物(合成樹脂)を着磁したもの(ゴム磁石、樹脂磁石など)が含まれる。   In order to magnetically attach the decorative cover 9 to the hole cover 8, a magnet is supported on one or both of the hole cover 8 and the decorative cover 9, and the other is made of a magnetic material. Here, the magnet includes magnets (rubber magnets, resin magnets, etc.) magnetized with a polymer compound (synthetic resin) containing rubber mixed with ferromagnetic powder in addition to a metal magnet.

上記孔カバー8や飾りカバー9に磁石を担持させる形態としては、孔カバー8や飾りカバー9の一部又は全部を磁石で形成する構成、孔カバー8や飾りカバー9と別体に形成された磁石を接着などにより孔カバー8や飾りカバー9に固定する構成などがある。   As a form for supporting the magnet on the hole cover 8 or the decorative cover 9, a part or all of the hole cover 8 or the decorative cover 9 is formed of a magnet, and is formed separately from the hole cover 8 or the decorative cover 9.
