When the downward claw of the hook 21b is positioned directly above the latching hole 35 of the latching member 20U and the lock member 21 is lowered from this state, the lower end 21a is latched with the latching hole 36, and the latching hook 21b is latched. Engage with the stop hole 35.

前記掛合状態からハンドル３９を持ってロック部材２１を上昇させると、下端２１ａと掛合フック２１ｂとはそれぞれの掛合が解除され、その解除状態からハンドル３９を持ってロック部材２１を回動すると、図９、１０に示すように、掛合フック２１ｂは掛止孔３５から外れ、ハンドル３９は縦杆５に設けた受け止め部材４０に載置可能になる。
受け止め部材４０は縦杆５に丸棒を溶着して形成されており、上昇位置のハンドル３９を受け止めて、ロック部材２１を連結解除位置に保持する役目をしている。 When the lock member 21 is lifted by holding the handle 39 from the hooked state, the lower end 21a and the hook hook 21b are released from each other, and when the lock member 21 is rotated by holding the handle 39 from the released state, FIG. As shown in 9 and 10, the hooks 21 b are detached from the retaining holes 35, and the handle 39 can be placed on the receiving member 40 provided on the vertical rod 5.
The receiving member 40 is formed by welding a round bar to the vertical rod 5 and serves to receive the handle 39 in the raised position and hold the lock member 21 in the connection release position.

従って、ハンドル３９を受け止め部材４０に保持した状態で、落下防止枠７を出入口Ｒａ塞閉姿勢に閉鎖していくと、縦杆５が当接部２０ａに当接して出入口塞閉位置が確定され、その状態でハンドル３９を受け止め部材４０から離脱する方向に回動し、そしてロック部材２１を下降させると、下端２１ａと掛合フック２１ｂとが掛止部材２０の掛止孔３５、３６に掛合する。   Accordingly, when the fall prevention frame 7 is closed to the entrance / exit Ra closed position while the handle 39 is held by the receiving member 40, the vertical rod 5 comes into contact with the contact portion 20a and the entrance / exit closed position is determined. In this state, when the handle 39 is pivoted in the direction of separating from the receiving member 40 and the lock member 21 is lowered, the lower end 21a and the engaging hook 21b are engaged with the engaging holes 35 and 36 of the engaging member 20. .

これにより、落下防止枠７は棚材３から手前に離れた状態で出入口Ｒａを塞閉することになり、ロック部材２１と掛止部材２０との掛合により棚材３に対して強固に保持され、棚材３上の物品が重量物であっても、確実に落下を規制できる。
なお、本発明は前記実施形態における各部材の形状及びそれぞれの前後・左右・上下の位置関係は、図１〜１２に示すように構成することが最良である。しかし、前記実施形態に限定されるものではなく、部材、構成を種々変形したり、組み合わせを変更したりすることもできる。 As a result, the fall prevention frame 7 closes the entrance / exit Ra in a state of being separated from the shelf 3 and is firmly held against the shelf 3 by the engagement of the lock member 21 and the latching member 20. Even if the article on the shelf 3 is heavy, the fall can be reliably controlled.
In the present invention, the shape of each member and the positional relationship between the front, rear, left, and right in the embodiment are best configured as shown in FIGS. However, it is not limited to the said embodiment, A member, a structure can be variously deformed, and a combination can also be changed.

例えば、落下防止枠７の左右縦杆５、上下横杆６等は四角パイプで形成されているが、丸パイプを用いてもよい。
連結具９は、ロック部材２１を上下動しかつ回動するようにしているが、受け止め部材４０を割愛して、ロック部材２１を上下動のみさせて、掛止孔３５、３６と掛合・離脱させるようにしてもよい。 For example, the left and right vertical rods 5 and the upper and lower horizontal rods 6 of the fall prevention frame 7 are formed of square pipes, but round pipes may be used.
The connector 9 moves the lock member 21 up and down and rotates, but omits the receiving member 40 and only moves the lock member 21 up and down to engage and disengage the latch holes 35 and 36. You may make it make it.

また、連結具９は、上下掛止部材２０に横向きの掛止孔３５、３６（又は掛止突起）を形成しておき、ロック部材２１に横向きの掛合フック２１ｂを上下一対設けておき、ロック部材２１を回動するだけで上下掛止部材２０を掛止孔３５、３６と掛合・離脱させるようにしてもよい。   Further, the connecting tool 9 is formed by forming the horizontal hooking holes 35 and 36 (or the hooking projections) in the upper and lower hooking members 20, and providing the pair of horizontal hooking hooks 21 b on the lock member 21. The upper and lower hooking members 20 may be engaged with and detached from the hooking holes 35 and 36 simply by rotating the member 21.
