次に本実施形態の動作について説明する。
昇降部材１４は、物品載置棚面１４ａにかかる重量による偏荷重により、第１及び第２レール面６，８，１０，１２を支点として、図２中、反時計方向に付勢されるとともに、第１のレール面６，８に弾接する突起体２０，２２からの弾発力により、係合体２８，３０が係合段部３４に圧着している。通常状態では、図５中、（１）に示すように、昇降部材１４側の係合体２８，３０は、係合段部３４の多数の段部３４ａの中の、１つの段部３４ａに弾発的に嵌合し、昇降部材１４はガイドレール部材２に係止されている。該係止状態において係合部分３２は係合段部３４の段部非形成面に対面している。 Next, the operation of this embodiment will be described.
The elevating member 14 is biased counterclockwise in FIG. 2 with the first and second rail surfaces 6, 8, 10, 12 as fulcrums due to the unbalanced load due to the weight applied to the article placement shelf surface 14 a. The engaging bodies 28 and 30 are pressure-bonded to the engaging step portion 34 by the elastic force from the projecting bodies 20 and 22 that elastically contact the first rail surfaces 6 and 8. In the normal state, as shown in (1) in FIG. 5, the engaging bodies 28 and 30 on the lifting member 14 side are elastic to one step portion 34 a among the many step portions 34 a of the engagement step portion 34. The lifting member 14 is locked to the guide rail member 2. In the locked state, the engaging portion 32 faces the stepped portion non-forming surface of the engaging stepped portion 34.

昇降部材１４の位置を変更するときは、昇降部材１４を図５（２）に示すように、下から持ち上げ、あるいは、昇降部材１４の上方部分をレール２に近づく方向に少し押すことにより、突起部１６，１８を中心として、昇降部材１４を、図５中、時計方向に揺動し、付勢用突起体２０，２２の弾発力に抗して、昇降部材１４の上部を、ガイドレール部材２の背面部２ａ方向に押し込む。昇降部材１４が、突起部１６，１８を中心として、時計方向に傾くと、係合体２８，３０が、係合段部３４の段部３４ａから外れる。 When changing the position of the elevating member 14, as shown in FIG. 5 (2), the elevating member 14 is lifted from below, or the upper portion of the elevating member 14 is slightly pushed in the direction approaching the rail 2 to make a protrusion. With the parts 16 and 18 as the center, the elevating member 14 is swung clockwise in FIG. 5, and the upper part of the elevating member 14 is guided against the elastic force of the urging projections 20 and 22 with the guide rail. The member 2 is pushed in the direction of the back surface 2a. When the elevating member 14 is tilted clockwise about the protrusions 16 and 18, the engagement bodies 28 and 30 are disengaged from the step 34 a of the engagement step 34.

次に昇降部材１４の物品載置棚面１４ａに載置した物品の重量により、昇降部材１４に下方向の力が作用し、若しくは人為的に昇降部材１４に下方向の力を作用させることで、昇降部材１４は、ガイドレール部材２に沿って下降するが、このとき、係合部分３２が図５（３）に示すように、段部３４ａに引っかかる。即ち、昇降部材１４は、係合体２８，３０の係合段部３４に対する係合が解除されても一気に降下しない。次に、昇降部材１４から手を離すと、突起体２０，２２の弾発力により、又は、物品載置棚面１４ａに載置した物品の重量により、昇降部材１４は、図５（４）に示すように、元の状態に戻ろうとし、下側の係合部分３２が、段部３４ａから外れる。次に昇降部材１４側の自重又は若干の下方の力により、昇降部材１４は、次の段部３４ａまで降下し、突起体２０，２２の弾発力又は昇降部材１４に作用する偏荷重で再度係合体２８，３０が図５（５）に示すように段部３４ａに入り込む。 Next, depending on the weight of the article placed on the article placement shelf surface 14 a of the elevating member 14, a downward force acts on the elevating member 14, or an artificial downward force is applied to the elevating member 14. The elevating member 14 descends along the guide rail member 2. At this time, the engaging portion 32 is caught by the stepped portion 34 a as shown in FIG. 5 (3). That is, the elevating member 14 does not descend at a stretch even when the engagement of the engagement bodies 28 and 30 with respect to the engagement step portion 34 is released. Next, when the hand is released from the elevating member 14, the elevating member 14 is shown in FIG. 5 (4) by the elastic force of the protrusions 20, 22 or by the weight of the article placed on the article placing shelf surface 14a. As shown in FIG. 3, the lower engaging portion 32 is disengaged from the step portion 34a. Next, due to the weight of the elevating member 14 or a slight downward force, the elevating member 14 descends to the next step 34a, and again by the elastic force of the protrusions 20 and 22 or the unbalanced load acting on the elevating member 14. The engaging bodies 28 and 30 enter the stepped portion 34a as shown in FIG.

以上の動作を繰り返して、昇降部材１４を所定の高さの段部３４ａに係止させることができる。昇降部材１４をガイドレール部材２に沿って上昇させるときは、昇降部材１４を手操作で持ち上げる。このとき、段部３４ａの傾斜面Ｓ２の作用によって、係合体２８，３０及び係合部分３２は、段部３４ａに係止されることなくガイドレール部材２に沿って上昇する。   The elevating member 14 can be locked to the stepped portion 34a having a predetermined height by repeating the above operation. When the elevating member 14 is raised along the guide rail member 2, the elevating member 14 is lifted manually. At this time, due to the action of the inclined surface S2 of the step portion 34a, the engaging bodies 28, 30 and the engaging portion 32 rise along the guide rail member 2 without being locked to the step portion 34a.

上記実施形態において、昇降部材１４は、進退自在な突起体２０，２２の弾発力によって、突起部１６，１８を中心として、図２中、反時計方向に付勢され、この付勢力によって、係合体２８，３０が、第２のレール面１０，１２に弾接し、該第２のレール面１０，１２に形成された係合段部３４に圧接しているが、昇降部材１４は自重により、偏荷重が作用しているため、前記付勢用の突起体２０，２２がなくとも、係合体２８，３０を係合段部３４に密嵌的に係合させ、昇降部材１４を片持ち支持することが可能である。   In the above-described embodiment, the elevating member 14 is urged counterclockwise in FIG. 2 around the protrusions 16 and 18 by the elastic force of the protrusions 20 and 22 that are movable back and forth, and by this urging force, The engaging bodies 28 and 30 are in elastic contact with the second rail surfaces 10 and 12 and are in pressure contact with the engaging step portions 34 formed on the second rail surfaces 10 and 12. Because the biased load is applied, the engaging members 28 and 30 are closely fitted to the engaging step portion 34 and the lifting member 14 is cantilevered without the biasing projections 20 and 22. It is possible to support.

次に本発明の他の実施形態を図６乃至図９を参照して説明する。
ガイドレール部材２の昇降ガイド部４の壁面には、長手方向に沿って傾斜面３６，３８が形成されている。該傾斜面３６，３８は、第２のレール面１０，１２を構成し、前記昇降ガイド部４の開口部４ａを前面方向に狭める方向に傾斜している。昇降部材１４には、その物品載置棚面１４ａにかかる荷重によって、後方部分１４ｂの両側立ち上がり部が傾斜面３６，３８にくい込むように、後方部分１４ｂの両側立ち上がり部に前記傾斜面３６，３８に対応して、楔形状面４０，４２が形成されている。 Next, another embodiment of the present invention will be described with reference to FIGS.
On the wall surface of the elevating guide portion 4 of the guide rail member 2, inclined surfaces 36 and 38 are formed along the longitudinal direction. The inclined surfaces 36, 38 constitute the second rail surfaces 10, 12, and are inclined in a direction to narrow the opening 4a of the elevating guide portion 4 in the front direction. The elevating member 14 has the inclined surfaces 36, 38 at the rising portions on both sides of the rear portion 14 b so that the rising portions on both sides of the rear portion 14 b are not easily inclined by the loads on the article mounting shelf surface 14 a. Corresponding to this, wedge-shaped surfaces 40 and 42 are formed.

前記楔形状面４０，４２は、前記傾斜面３６，３８に平行に対面するように構成されている。前記傾斜面３６，３８には、係合段部３４が設けられ、該係合段部３４に対応して、前記昇降部材１４の楔形状面４０，４２には、係合体２８，３０と係合部分３２が設けられている。係合部分３２は、図９に示すように傾斜面４２を兼ねている。この係合体２８，３０と係合部分３２の構成及び他の構成は第１の実施形態の構成と同一であり、対応する部分には同一の符号を付している。尚、前記傾斜面３６，３８は第１のレール面６，８側に設けるようにしても良い。 The wedge-shaped surfaces 40 and 42 are configured to face the inclined surfaces 36 and 38 in parallel. Engagement step portions 34 are provided on the inclined surfaces 36, 38, and the wedge-shaped surfaces 40, 42 of the elevating member 14 are associated with the engagement bodies 28, 30 corresponding to the engagement step portions 34. A mating portion 32 is provided. The engaging portion 32 also serves as an inclined surface 42 as shown in FIG. The configurations of the engaging bodies 28 and 30 and the engaging portion 32 and other configurations are the same as those of the first embodiment, and corresponding portions are denoted by the same reference numerals. The inclined surfaces 36 and 38 may be provided on the first rail surfaces 6 and 8 side.

上記した構成において、昇降部材１４の物品載置棚面１４ａにかかる荷重によって、昇降部材１４は、図７中、第１のレール面６，８及び第２のレール面１０，１２を支点として、反時計方向に傾斜しようとする。この傾斜しようとする力と、突起体２０，２２の弾発力とによって、昇降部材１４には、昇降ガイド部４から前方に突出しようとする力が作用する。この力により昇降部材１４の楔形状面４０，４２が傾斜面３６，３８にくい込み、昇降部材１４はガイドレール部材２の昇降ガイド部４の壁面に強固に保持される。   In the above configuration, due to the load applied to the article placement shelf surface 14a of the elevating member 14, the elevating member 14 has the first rail surfaces 6, 8 and the second rail surfaces 10, 12 in FIG. Try to tilt counterclockwise. Due to the force to incline and the elastic force of the protrusions 20 and 22, a force to project forward from the lifting guide portion 4 acts on the lifting member 14. By this force, the wedge-shaped surfaces 40 and 42 of the elevating member 14 are not easily inclined, and the elevating member 14 is firmly held on the wall surface of the elevating guide portion 4 of the guide rail member 2.

これにより係合体２８，３０が強く係合段部３４に圧着し、これらの係合を簡単に外れないように強固なものとする。また昇降部材１４の横方向の移動が強固に規制される。昇降部材１４の上下方向の位置を変更する動作は、第１の実施形態で説明した動作と同一である。尚、上記実施形態はいずれも、係合段部３４の段部３４ａを歯溝としたが、図１０に示すように溝ではなく、突起４４を設け、この突起により係合段部３４を構成するようにしてもよい。 As a result, the engagement bodies 28 and 30 are strongly pressed against the engagement step portion 34, and the engagement bodies 28 and 30 are made strong so that they cannot be easily disengaged. Further, the lateral movement of the elevating member 14 is firmly restricted. The operation of changing the vertical position of the elevating member 14 is the same as the operation described in the first embodiment. In each of the above embodiments, the step 34a of the engagement step 34 is a tooth groove. However, as shown in FIG. 10, a protrusion 44 is provided instead of the groove, and the engagement step 34 is configured by this protrusion. You may make it do.

これらの突起４４はそれぞれ昇降部材１４の上昇を可能とする傾斜面と、昇降部材１４側の係合体２８，３０と係合し、これを支える係止面を有している。図１０の実施形態では、昇降部材１４の一気の落下を阻止する係合部分３２に相当する部分は、昇降部材１４の後方部分１４ｂの両側立ち上がり部の下端のエッヂ４６が担当する。 Each of these protrusions 44 has an inclined surface that allows the elevating member 14 to rise, and a locking surface that engages and supports the engaging bodies 28 and 30 on the elevating member 14 side. In the embodiment of FIG. 10, the edge 46 at the lower end of the rising portions on both sides of the rear portion 14 b of the elevating member 14 is in charge of the portion corresponding to the engaging portion 32 that prevents the elevating member 14 from dropping at once.
