Description

本発明は、手動式移動棚装置に係わり、更に詳しくはハンドル操作によって各移動棚の駆動輪を回転させて移動させる方式の手動式移動棚装置に関するものである。 The present invention relates to a manual type moving shelf device, and more particularly to a manual type moving shelf device in which a driving wheel of each moving shelf is rotated and moved by a handle operation.

従来から、前面パネルに設けたハンドルによって回転駆動される車輪を有する複数台の移動棚を、それらの出入面に対して直交する方向に敷設したレールに沿って移動可能に配置し、移動棚の移動でそれらの間に所定幅の通路が形成される手動式移動棚装置は各種提供されている。 Conventionally, a plurality of movable shelves having wheels that are rotationally driven by a handle provided on the front panel are arranged so as to be movable along rails laid in a direction perpendicular to the entrance and exit surfaces of the movable shelves. Various types of manually-operated moving shelf devices are provided in which a passage having a predetermined width is formed between them by movement.

特許文献１には、移動棚の下端で各レールに対応した位置に、駆動輪と単又は複数の従動輪を設け、各移動棚の前面パネルに設けたハンドルの回転力を前記駆動輪に伝達する回転力伝達機構を備え、該回転力伝達機構は大小のスプロケット又は歯付きプーリからなる一対の回転体と、両回転体に巻回するチェーン又はタイミングベルトからなる無端索体とからなり、使用者がハンドルを回転させて移動棚を移動させ、所定の移動棚間又は側端部に配置した固定棚と移動棚間に通路を形成し、その通路内に使用者が入って該通路に面した出入面から書籍やファイル等の物品を出し入れすることが可能な手動式移動棚装置が開示されている。ここで、前記ハンドルは、軸部から直角に延びたアームの先端部につまみを設けた構造で、各移動棚の前面パネルから前方へ突出する状態で設けられている。 In Patent Document 1, a driving wheel and one or a plurality of driven wheels are provided at positions corresponding to the rails at the lower end of the moving shelf, and the rotational force of the handle provided on the front panel of each moving shelf is transmitted to the driving wheel. The rotational force transmission mechanism comprises a pair of rotating bodies consisting of large and small sprockets or toothed pulleys, and an endless cord body consisting of a chain or timing belt wound around both rotating bodies. The user rotates the handle to move the movable shelf to form a passage between a predetermined movable shelf or between the fixed shelf and the movable shelf arranged at the side end, and the user enters the passage to face the passage. There has been disclosed a manual moving shelf device capable of taking in and out articles such as books and files from the access surface. Here, the handle has a structure in which a knob is provided at the tip of an arm that extends perpendicularly from the shaft, and is provided in a state of protruding forward from the front panel of each movable shelf.

また、特許文献２，３には、各移動棚の前面パネルに前方へ突出するように円形のハンドルを設け、ハンドルの回転力を駆動輪に伝達して移動可能な状態と移動不能な状態に切り替えることができるクラッチ機構若しくはロック機構をハンドルの軸部に設け、ハンドルを軸方向に変位させることによりその機構の切り替えができる構造が開示されている。しかし、何れの状態においてもハンドルは移動棚の前面パネルよりも手前に突出した状態である。 Further, in Patent Documents 2 and 3, a circular handle is provided on the front panel of each movable shelf so as to protrude forward, and the rotational force of the handle is transmitted to the drive wheel so that the movable wheel can move and the movable wheel cannot move. There is disclosed a structure in which a clutch mechanism or a lock mechanism that can be switched is provided in a shaft portion of a handle, and the mechanism can be switched by displacing the handle in the axial direction. However, in any state, the handle is in a state of protruding forward from the front panel of the movable shelf.

また、特許文献４には、移動棚の側面（前面パネル）に設けた操作ハンドルが、ホイールと該ホイールに設けたノブとからなり、該ノブは奥行方向にスライド可能に保持されているとともに、引き込み方向にバネで弾性付勢された構造が開示されている。ここで、操作ハンドルの非操作時にはノブは、バネによる付勢力によって突出量が最小の状態にあるが、操作時にノブに指を掛けることによりバネの付勢力に抗して手前へ突出した状態となり、ホイールを回転させることができるのである。この場合、ノブから指を離せば自動的に引き込まれ、ノブの突出量が最小となる。しかし、非操作時においても、ノブの前方頂部はホイールの前面から突出した状態にあるので、少なくともその分だけ移動棚の前面パネルから突出した状態となる。 Further, in Patent Document 4, an operation handle provided on the side surface (front panel) of the movable shelf includes a wheel and a knob provided on the wheel, and the knob is slidably held in the depth direction. A structure that is elastically biased by a spring in the retracting direction is disclosed. Here, when the operation handle is not operated, the knob has a minimum protruding amount due to the urging force of the spring, but when operated, the knob protrudes toward the front against the urging force of the spring by placing a finger on the knob. The wheel can be rotated. In this case, when the finger is released from the knob, it is automatically pulled in, and the protruding amount of the knob is minimized. However, even during non-operation, the front top of the knob is in a state of protruding from the front surface of the wheel, and thus is in a state of protruding from the front panel of the movable shelf at least by that amount.

It should be noted that the handle 52 and its accessory parts are heavy, and the handle body 51 on the opposite side of the handle 52 is placed on the opposite side of the handle 52 so that the handle 7 rotates unexpectedly due to the weight and the movable shelf 1 does not move. It is also preferable to provide a counterweight that cancels the rotational moment.

ここで、前記把手５２を使用状態に維持するために、前記ローラープランジャ７１よりも前方位置に第２のローラープランジャ７４を前記支持部材６６に設けて、前記可動体６４の係合突起７２の後部を当止するようにすることも好ましい。つまり、前記把手保持手段６３を一対のローラープランジャ７１，７４と係合突起７２とで構成し、格納状態と使用状態を維持するようにしても良い。この場合、図１１の把手５２を押し込んだ状態から指を離せば、前記係合突起７２が前記ローラープランジャ７１と前記ローラープランジャ７４を自動的に通過することが好ましいが、第２のローラープランジャ７４を通過しなければ、突出してきた前記把手５２を持って引っ張り出し、前記係合突起７２が強制的に通過させても良い。尚、第２のローラープランジャ７４の代わりに、前記可動体６４と前記取付板６７の少なくとも何れか一方にマグネットを固定し、他方の磁性部材を吸着させて使用状態を維持しても良い。 Here, in order to maintain the handle 52 in a use state, a second roller plunger 74 is provided on the support member 66 at a position in front of the roller plunger 71, and the rear portion of the engagement protrusion 72 of the movable body 64. It is also preferable to stop. That is, the handle holding means 63 may be composed of a pair of roller plungers 71 and 74 and the engaging protrusion 72 to maintain the retracted state and the used state. In this case, it is preferable that the engagement protrusion 72 automatically passes through the roller plunger 71 and the roller plunger 74 if the finger is released from the state where the handle 52 of FIG. If it does not pass, it may be pulled out by holding the protruding handle 52 and the engaging projection 72 may be forced to pass. Instead of the second roller plunger 74, a magnet may be fixed to at least one of the movable body 64 and the mounting plate 67, and the other magnetic member may be attracted to maintain the use state.

そして、前記ハンドル本体５１の表面から突出した前記把手５２を格納状態にするには、前記把手５２を押し込み、前記ローラープランジャ７１を通過させた後に、ゆっくりと指を離せば該ローラープランジャ７１に係合突起７２が当止して静止する。ここで、前記係合突起７２は、前部が急峻に立ち上がった面で、後部が傾斜した面となっており、断面略直角三角形状となっている。これは、前記把手５２を押し込み時にローラープランジャ７１を通過させ易く、また格納状態で確実にローラープランジャ７１に当止させて静止させるためである。 Then, in order to put the handle 52 protruding from the surface of the handle body 51 into the retracted state, the handle 52 is pushed in, passed through the roller plunger 71, and then slowly lifted to release the handle. The mating protrusion 72 stops and stops. Here, the engaging protrusion 72 has a front surface that rises sharply and a rear surface that is inclined, and has a substantially right-angled cross section. This is because the roller plunger 71 can be easily passed when the handle 52 is pushed in, and the handle 52 is surely stopped by being brought into contact with the roller plunger 71 in the retracted state.

尚、前記ハンドル本体５１の一部に設けた把手５２が、前記ハンドル本体５１の表面から突出しない格納状態にあっても、該ハンドル本体５１の外側面７Ａに指を当て、指と外側面７Ａとの摩擦力を利用してハンドル７を回転させ、移動棚１を移動させることも可能である。勿論、前記把手５２をハンドル本体５１から手前に突出させて、該把手５２を持って回転させる方が楽に操作できる。 Even when the handle 52 provided on a part of the handle main body 51 is in a retracted state where it does not protrude from the surface of the handle main body 51, a finger is applied to the outer side surface 7A of the handle main body 51, It is also possible to move the movable shelf 1 by rotating the handle 7 using the frictional force. Of course, it is easier to operate the handle 52 by projecting the handle 52 forward from the handle body 51 and rotating the handle 52.

前記把手保持手段６３の変形例を、図１３〜図１５に基づいて簡単に説明する。図１３は、第２発明のハンドルの第１変形例を示し、前記把手保持手段６３が、位置決めピン７５と係合突起７２とで構成されたものである。前記位置決めピン７５は、ボールプランジャと同様な半球状の頭部が内蔵した弾性部材によって突出方向に弾性付勢された構造であり、市販品を用いることができる。また、第２の前記ローラープランジャ７４と同様に、第２の位置決めピン７６を設けることも好ましい。 A modification of the handle holding means 63 will be briefly described with reference to FIGS.

The positioning pin 75 has a structure in which a hemispherical head similar to a ball plunger is elastically urged in the protruding direction by a built-in elastic member, and a commercially available product can be used. Further, similarly to the second roller plunger 74, it is also preferable to provide a second positioning pin 76.

図１４は、第２発明のハンドルの第２変形例を示し、前記把手保持手段６３が、板バネ７７と係合突起７２とで構成されたものである。また、第２の前記ローラープランジャ７４と同様に、第２の板バネ７８を設けることも好ましい。 FIG. 14 shows a second modification of the handle according to the second aspect of the invention, wherein the handle holding means 63 is composed of a leaf spring 77 and an engaging projection 72. Further, similarly to the second roller plunger 74, it is also preferable to provide a second leaf spring 78.

図１５は、第２発明のハンドルの第３変形例を示し、前記把手保持手段６３が、マグネット７９と磁性体８０とで構成されたものである。ここで、前記マグネット７９は、前記支持部材６６にホルダー８１を介して固定し、前記磁性体８０は、前記可動体６４の外周面自体で構成し、あるいは位置決めを正確にするために対向マグネットを設けても良い。また、第２の前記ローラープランジャ７４と同様に、第２のマグネット８２を設けることも好ましい。 FIG. 15 shows a third modification of the handle of the second invention, wherein the handle holding means 63 is composed of a magnet 79 and a magnetic body 80. Here, the magnet 79 is fixed to the support member 66 via a holder 81, and the magnetic body 80 is constituted by the outer peripheral surface of the movable body 64 itself, or an opposing magnet is used for accurate positioning. It may be provided. Further, similarly to the second roller plunger 74, it is also preferable to provide a second magnet 82.

尚、前記ローラープランジャ、位置決めピン及び板バネは、適宜組み合わせて用いることも可能である。つまり、格納状態と使用状態とで異なる構成の係合手段を組み合わせて前記把手保持手段６３を構成しても良い。また、前記受板６９には、前記把手５２を押し込んだ際に、前記可動体６４を当止するゴム製のストッパー８３を適宜設けている。 The roller plunger, the positioning pin and the leaf spring can be used in appropriate combination. That is, the handle holding means 63 may be configured by combining engagement means having different configurations in the storage state and the use state. Further, the receiving plate 69 is appropriately provided with a rubber stopper 83 that stops the movable body 64 when the handle 52 is pushed.
