【０００１】
【発明の属する技術分野】
本発明は，二段床を昇降可能に収納し，ステージ機能も併せもつ荷箱に関し，とくに，二段床にもステージ機能をもたせることができる荷箱に関する。
【０００２】
【従来の技術】
各種の荷物を運搬するために，トラックなどの車両が利用されるが，このようなトラックは荷物を搬入，搬出する荷箱を有している。
【０００３】
荷物は一般に種々の大きさ，重量を有しているが，荷箱内を有効に使用するために，さらには荷物の搬入，搬出を容易にするために，荷箱内にもう一つの床を設け，これを二段床として，駆動手段により昇降可能としている。
【０００４】
二段床を昇降可能に収納した荷箱をもつ車両は，二段床の位置を調節することにより，種々の大きさ，重量をもつ荷物を有効に積み込むことができ，荷箱内の空間を有効に利用できるといる特徴をもつ。
【０００５】
ところで，荷箱の側面を開放し，荷台をステージとして利用するトラックが利用されている。このようトラックは所望の場所に移動して，野外ステージとして，また種々の宣伝広告のために利用できる。
【０００６】
トラックの荷箱の床がステージとして利用するのには狭すぎるとき，荷箱の側壁，煽りを回転させて水平に支持し，ステージとして使用している。
【０００７】
【発明が解決しようとする課題】
ステージ機能をもつ荷箱の床は平らでなければならず，また水平に支持される側壁，煽りと同一面上になけられならない。そのために，ステージ機能をもつ荷箱内に荷物を搬入するときは，単に荷物を積み重ねるしかなく，荷箱内の空間を有効に利用することができない。
【０００８】
一方，二段床を昇降可能に収納した荷箱は，二段床の配置する高さを調節することで，荷箱内の空間を有効に利用できるが，二段床を下降させ，最下位に位置させたとき，二段床の高さの分だけ，煽りや，側壁部の位置より高くなり，そのため，これらは同一平面とならず，ステージとして使用しにくいものとなる。
【０００９】
また，荷箱内において，二段床を所望の位置に，固定，支持する手段が必要となる。そのため，二段床を収納した荷箱を，ステージ機能を有する荷箱として使用すると，その固定，支持手段が邪魔になり，ステージ機能を阻害する。
【００１０】
そこで，本発明は，かかる課題を解決するためになされたものであり，二段床を昇降可能に収納した荷箱において，二段床とステージ部，煽りとが同一面となる，ステージ機能をもつ荷箱を提供することを目的とする。
【００１１】
本発明の他の目的は，二段床と同一面とすることができる，枢着された側壁をステージ部として使用する上記荷箱を提供することである。
【００１２】
さらに，本発明の目的は，二段床と同一面とすることができるステージ部を着脱自在に取り付けすることができる上記荷箱を提供することである。
【００１３】
さらに，本発明の他の目的は，荷箱内において昇降可能に収納された二段床を，任意の位置に，固定，支持する手段が，荷箱内の空間を実質的に占めない上記荷箱を提供することである。
【００１４】
【課題を解決するための手段】
本発明の荷箱は，ウイング式屋根と煽りにより両側面を開閉できる，二段床を昇降可能に収納した荷箱であって，ウイング式屋根および煽りと，二段床との間に収納されて，当該荷箱に枢着されるステージ部を有する。ステージ部は，荷箱において下降して，最下位に位置した二段床と，水平に回転させたステージ部とが同一平面となる位置に枢着される。
【００１５】
ステージ部が収納されていない側の煽りもまた荷箱に枢着されるが，この枢着位置は，煽りを回転させて水平にしたとき，荷箱において下降して，最下位に位置した二段床と，同一平面となる位置であることが望ましい。
【００１６】
ステージ部を荷箱内に収納する代わりに，荷箱において下降して，最下位に位置した二段床と同一平面となる位置に，荷箱に着脱自在に取り付けてもよい。
【００１７】
ウイング屋根をもつ荷箱に代えて，荷箱の側面が，枢着されたステージ部により開閉される荷箱も使用できる。ここで，荷箱において下降して，最下位に位置した二段床と，水平に回転させたステージ部とが同一平面となる位置に，ステージ部は枢着される。
【００１８】
二段床を収納可能に収納した荷箱は，二段床を昇降移動に案内する複数の案内枠材と，二段床に固定され，案内枠材内で移動可能なスライドブロックと，二段床を昇降するために，スライドブロックに連結される駆動機構と，二段床を所定の位置に固定，支持するロック装置と，を含んでもよい。
【００１９】
ここで，ロック装置は，昇降床の側面に隣接して配置される枠材と，昇降床を所定の位置に配置するための，枠材に取り付けられるストッパ部とを含む。ストッパ部は，背面部と，該背面部の上端から水平に伸びる頂部と，背面部の下端から頂部にそって伸びる底部とを含む。背面部は，少なくとも片側から突き出る突き出し部を有する。枠材は，枠材背面壁と，間にストッパ部の頂部および底部を配置できる両側壁と，該側壁の先端からストッパ部の突き出し部と接触可能な張り出し部とを有する。所定の位置に，昇降床を下から支えるために，枠材背面壁には，ストッパ部の頂部および底部の先端部のそれぞれを挿入できる穴部が形成され，張り出し部に，ストッパ部の突き出し部を下から支持するストップ片が固定される。
【００２０】
本発明の荷箱をステージとして使用するときは，二段床を最下位に位置させるとともに，枢着されたステージ部を回転させて水平に維持する。ステージ部は，最下位に位置する二段床と同一平面上にあるから，二段床およびステージ部全体がステージとして使用できる。枢着された煽りも同様に，水平に回転させることで，同様にステージとして使用できる。
【００２１】
本発明の荷箱に荷物を搬入するときは，二段床を駆動する装置により，所定に位置まで上昇，または下降させて，固定して維持する。この固定，支持のために，ロック装置を使用するときは，二段床を所定の位置よりやや高い位置に配置し，ストッパ部の頂部および底部を，枠材の所定の位置にある穴部に挿入し，ストッパ部の突き出し部を，枠材の張り出し部に接触させるとともに，ストップ片により下から支えられるようにする。そして，二段床を所定の位置まで下降させることで，二段床は，所定の位置にストッパ部により，固定，支持される。
【００２２】
【発明の実施の態様】
図１は，本発明を実施した，二段床とステージを兼ね備えた荷箱を有するトラックの背面図である。図１のトラックの荷箱1は，ウイング式の屋根2と，煽り3，3’とにより，両側面が開閉可能となっている。この荷箱には，二段床5が昇降可能に収納されている。二段床を昇降可能に荷箱に収納する技術は従来より知られており，また本発明の範囲外であることから，説明を省略する。荷箱内で，二段床を所望の位置に，固定，支持するロック装置は，従前のものより行えるが，本荷箱にステージ機能をもたせるためには，荷箱内で邪魔のならないロック装置が望ましく，このようなロック装置は以下で説明する。
【００２３】
図１に示されているように，二段床を所定の位置に固定，支持すると，荷物の搬入を適切に行え，これにより，荷箱内の空間を有効に利用することができる。図１において，二点破線により示されているように，二段床は，最下位の位置に配置するときは，この二段床をステージの一部として機能させることもできる。
【００２４】
ウイング式屋根2および煽り3と，二段床5との間にステージ部6が配置されている。煽り3は，荷箱の床部7の付近に枢着されているが，ステージ部6は，図２に示されているように，最下位に位置した二段床5と同一面となるように，荷箱1に枢着されている。
【００２５】
この荷箱において，ステージ部6を使用するために，二段床5を最下位の位置に配置する。つぎに，図２および図３に示されているように，ウイング式屋根2および煽り3を回転させて側面を開放する（図３では，二段床5を図示するために，中央に配置する）。さらに，ステージ部6を，枢着点を中心に回転させ水平にする。ここで，水平を維持するために，脚部8を垂直にセットする。これにより，二段床5とステージ部6とが同一面にあり，広いステージが完成する。
【００２６】
さらに，図２および図４に示されているように（図４では，図３と同様に二段床5は中央に位置する）煽り3’を，枢着点を中心に回転させ，水平にする。脚部9により，煽り3’は水平に維持されている。これにより，ステージ部6，二段床5および煽り3’が同一平面となり，より広いステージが完成する。
【００２７】
この実施例では，ステージ部6は荷箱1に枢着されているが，荷箱に着脱自在に取り付けてもよい（この場合，ステージ部6は，荷箱内に搬入しておくか，あるいは別途運ぶことになる）。
【００２８】
また，ウイング式屋根をもつ荷箱を例としたが，ウイング屋根に代え，側面をステージ部により開閉できるようにした荷箱も使用できる。この場合でも，ステージ部の取り付け点は，最下位の位置に二段床が位置するときに，これと同一面となる位置にする。
【００２９】
前述したように，二段床は従来技術により荷箱内に，昇降可能に収納され，所定の位置に，従来技術のロック装置により，固定され得るものであるが，荷箱にステージ機能，すなわち，荷箱内の床部をより有効に使用するためには，ロック装置が邪魔になることは望ましくない。
【００３０】
図５から図８を参照して，荷箱のステージ機能をもたせるのに好適なロック装置を説明する。
【００３１】
図５にロック装置の拡大斜視図が，図６にロック装置を構成するストッパ部の斜視図が，図７にロック装置を構成する枠材の斜視図が示されている。
【００３２】
図６（A）はストッパ部の背面からの斜視図，図６（B）はストッパ部の正面からの斜視図を示す。図６に示されているように，ストッパ部20は全体として矩形形状をもつが，その背面部21と，その上端から水平に伸びる頂部22と，さらに，背面部21の下端から，頂部22にそって伸びる底部23を有する。背面部21の両側から，それぞれ突き出る突き出し部24および25を有する。頂部22および底部23のそれぞれの先端は下方に湾曲している。さらに，頂部22と底部23との間に，二枚の補助片26および27が固着されている。この補助片は，ストッパ部20の剛性を高めるだけではなく，以下で説明するように，ストッパ部が緩むことなく確実に枠材に取り付けられるようにするが，本発明において，必須の要件ではない。
【００３３】
図７（A）は枠材の正面からの斜視図，図７（B）は枠材の背面からの斜視図を示す。
【００３４】
前記したように，車両の荷箱の組み込まれる二段床は，図２および図３に示されているように，二段床に固定されたスライドブロックが移動可能な案内枠材により昇降可能に案内されるが，この昇降のための枠材と，ロック装置の枠材を併設した例が，図７に示されている。
【００３５】
枠材30は，ロック装置の枠材30aと，昇降のための枠材30bとの側面が接合して構成されている。枠材30a（枠材30bも同様）は，枠材背面壁31と，間にストッパ部の頂部22および底部23を配置できる両側面32，33を有し，さらに，その側面から内側に張り出す張り出し部32’および33’を有する。この実施例では，張り出し部はそれぞれ内側に張り出すことから，張り出し部の間は，ストッパ部の頂部22と底部23の幅にほぼ等しくなる。
【００３６】
枠材背面壁31には，ストッパ部の頂部22および底部23の下方に湾曲した先端が，ストッパ部を水平にした状態で，通ることができる各貫通穴34，35が，二つ一組で，二段床を所望の位置に位置付けする位置にあけられている（図７（B））。
【００３７】
ストッパ部の頂部22および底部23の先端は湾曲していることから，図８にも示されているように，ストッパ部を枠材に取り付けたとき，その先端と枠材の背面壁の間に間隙が生じないように，補助突起部36，37が枠材の背面壁の背面の固着されている。したがって，補助突起は各穴の下方に設けられる。
【００３８】
さらに，図５により詳細に示されているように，ストッパ部を枠材に取り付けて，頂部22および底部23の下面を穴の下縁に接しさせると，ストッパ部の突き出し部24，25は，枠材の張り出し部32’，33’と接するが，このとき，突き出し部24，25を下から支えるための，ストップ片41，42が張り出し部32’，33’のそれぞれに設けられている。
【００３９】
ロック装置のロック操作を，図を参照して説明する。
図８（A）に示されているように，二段床5を所定の位置のやや上方に位置させ，図５に示されているように，ストッパ部20を，枠材30に接近させ，図８（A）に示されているように，両側壁の間に入れる。続いて，図８（B）に示されているように，ストッパ部20の頂部22および底部23の湾曲した先端を，枠材の貫通穴34，35にそれぞれ挿入して，補助片26，27の端面が枠材の背面部31の表面に接するようにする。さらに，その状態で，ストッパ部20を下降させる。
【００４０】
図８（C）に示されているように，ストッパ部20が下降し，頂部22および底部23の下面が，貫通穴34，35の下縁と接するとき，頂部22および底部23の先端の下側は補助突起36，37と接し，ストッパ部20の突き出し部24，25は，ストップ片32’，33’に接して，ストップ片41，42により下から支持される。
【００４１】
この状態で，二段床5が下降し，ストッパ部20の頂部22に接することで，二段床は下から支持され，したがって，任意の位置で，固定，支持される。上記説明は一つの枠材についてストッパ部の取り付けについてであるが，他の枠材への取り付けも同様である。ストッパ部の取り外しは，上記取り付け操作を逆にすることで容易に取り外すことができる。
【００４２】
図５，図７において図示した枠材は，ロック装置を構成する枠材と，二段床を昇降するためのスライドブロックが収納される案内枠材とを兼ねたものであるが，両枠を別々にして荷箱に設けることも可能である。
【００４３】
ストッパ部の突き出し部は，背面部の両端から突き出しているが，二段床の重量，大きさなどによっては，一方のみでも機能する。このとき，ストップ片もこれに対応して一つとなる。
【００４４】
上記したように，枠材30を別個に設けたとき，枠材の張り出し部32’，33’は，内側でなく外側に張り出してもよい。
【００４５】
図示のストッパ部の頂部22および底部23の先端は，湾曲を描いて下方に曲がっているが，ほぼ直角に曲がるときは，先端の内側は，枠材背面壁の背面に，間隔があくことなく接することができることから，補助突起は不要となる。
【００４６】
以上にように，ロック装置は，非常にコンパクトであり，荷箱内の空間を実質的に占めない。そのため，二段床を使用して荷物を搬入するに際しても，また荷箱をステージとして使用するに際しても，邪魔なものとならない。
【００４７】
【効果】
上記説明したように，本発明にしたがって，ステージ部および/または煽りが水平に回転し，最下位に位置する二段床と同一平面となり，荷箱がステージ機能をもつことができる。
【００４８】
また，二段床を所定の位置に，固定，支持すると，荷箱内へ荷物の搬入において，荷箱内の空間を有効に利用することができる。
【００４９】
さらに，本発明にしたがって，ロック装置を使用することで，二段床を所定の位置に，固定，支持することができるために，一層，荷箱内へ荷物の搬入において，荷箱内の空間を有効に利用することができる。
【００５０】
さらにまた，本発明にしたがって，ロック装置を使用すると，ロック装置が荷箱内の空間を実質的に占めないため，二段床を使用するときも，荷箱をステージとして使用するときも，ロック装置はその使用を阻害することがない。

BACKGROUND OF THE INVENTION
The present invention relates to a packing box that stores a two-stage floor in a vertically movable manner and also has a stage function, and more particularly, to a packing box that can also provide a stage function to a two-stage floor.
[0002]
[Prior art]
A vehicle such as a truck is used to carry various kinds of luggage. Such a truck has a packing box for carrying in and out the luggage.
[0003]
Baggage generally has various sizes and weights, but in order to use the inside of the packing box effectively, and to facilitate loading and unloading of the baggage, another floor is put in the packing box. It is provided as a two-stage floor, and can be moved up and down by driving means.
[0004]
Vehicles with a packing box that can store the second floor so that it can be moved up and down can be loaded effectively with various sizes and weights by adjusting the position of the second floor. It has the feature that it can be used effectively.
[0005]
By the way, trucks are used that open the side of the packing box and use the loading platform as a stage. Such a truck can be moved to a desired location and used as an outdoor stage and for various advertising.
[0006]
When the floor of a truck's packing box is too narrow to be used as a stage, the side walls and the ridges of the packing box are rotated and supported horizontally to be used as a stage.
[0007]
[Problems to be solved by the invention]
The floor of the packing box with the stage function must be flat and must be flush with the horizontally supported side walls. For this reason, when a package is loaded into a packing box having a stage function, it is only possible to stack the loads, and the space in the packing box cannot be used effectively.
[0008]
On the other hand, a packing box that houses a two-tiered floor can be used effectively by adjusting the height of the two-tiered floor. When it is placed on the floor, the height of the second floor is higher than the height of the wall and the side wall, so they are not coplanar and difficult to use as a stage.
[0009]
In addition, a means for fixing and supporting the second floor at a desired position in the packing box is required. For this reason, when a packing box containing a two-stage floor is used as a packing box having a stage function, its fixing and supporting means become an obstacle, and the stage function is hindered.
[0010]
Therefore, the present invention has been made in order to solve such a problem, and has a stage function in which a two-tier floor, a stage portion, and a ridge are on the same plane in a packing box that accommodates the two-tier floor in a vertically movable manner. The purpose is to provide packing boxes.
[0011]
Another object of the present invention is to provide the above-mentioned packing box using a pivoted side wall as a stage part, which can be flush with the two-step floor.
[0012]
Furthermore, the objective of this invention is providing the said packing box which can attach the stage part which can be made into the same surface as a two-step floor so that attachment or detachment is possible.
[0013]
Furthermore, another object of the present invention is to provide the above-mentioned load in which the means for fixing and supporting the two-tiered floor accommodated in the packing box at an arbitrary position does not substantially occupy the space in the packing box. Is to provide a box.
[0014]
[Means for Solving the Problems]
The packing box of the present invention is a packing box that can open and close both sides by a wing-type roof and a roof, and that can be moved up and down, and is stored between the wing-type roof and the roof and the two-step floor. And a stage portion pivotally attached to the packing box. The stage part descends in the packing box, and is pivotally attached to the position where the two-level floor located at the lowest position and the stage part rotated horizontally are in the same plane.
[0015]
The turn on the side where the stage part is not stored is also pivotally attached to the packing box. This pivoting position is lowered in the packing box when the turn is rotated and leveled. It should be in the same plane as the corrugated floor.
[0016]
Instead of storing the stage portion in the packing box, it may be detachably attached to the packing box at a position that is lowered in the packing box and is flush with the two-level floor located at the lowest position.
[0017]
Instead of a packing box with a wing roof, a packing box whose side is opened and closed by a pivoted stage part can also be used. Here, the stage part is pivotally attached to a position where the two-stage floor positioned at the lowest position and the stage part rotated horizontally are flush with each other.
[0018]
The packing box that can store the second floor is composed of a plurality of guide frames that guide the second floor to move up and down, a slide block that is fixed to the second floor and is movable within the guide frame, In order to move up and down the floor, a drive mechanism connected to the slide block and a lock device for fixing and supporting the two-step floor at a predetermined position may be included.
[0019]
Here, the lock device includes a frame member disposed adjacent to the side surface of the lifting floor and a stopper portion attached to the frame member for positioning the lifting floor at a predetermined position. The stopper portion includes a back surface portion, a top portion extending horizontally from the upper end of the back surface portion, and a bottom portion extending along the top portion from the lower end of the back surface portion. The back portion has a protruding portion protruding from at least one side. The frame member has a frame member rear wall, both side walls on which the top and bottom portions of the stopper portion can be disposed, and an overhanging portion that can come into contact with the protruding portion of the stopper portion from the tip of the side wall. In order to support the lifting floor from below at a predetermined position, a hole is formed in the rear wall of the frame material so that each of the top and bottom tips of the stopper can be inserted. The stop piece that supports the stool from below is fixed.
[0020]
When the packing box of the present invention is used as a stage, the second floor is positioned at the lowest position and the pivoted stage portion is rotated and kept horizontal. Since the stage part is on the same plane as the lowest two-level floor, the entire two-level floor and the stage part can be used as the stage. Similarly, the pivoted ring can be used as a stage by rotating horizontally.
[0021]
When a package is carried into the packing box of the present invention, it is fixed and maintained by raising or lowering it to a predetermined position by a device that drives a two-step floor. When using a locking device for fixing and supporting, place the two-tiered floor at a position slightly higher than the predetermined position, and place the top and bottom of the stopper part in the hole at the predetermined position of the frame material. inserted, the projecting portion of the stopper portion, with contacting the extending portion of the frame member, so that is supported from below by the stop piece. Then, by lowering the second floor to a predetermined position, the second floor is fixed and supported at a predetermined position by a stopper portion.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a rear view of a truck having a packing box having both a two-tiered floor and a stage according to the present invention. The truck's packing box 1 in FIG. 1 can be opened and closed on both sides by a wing-type roof 2 and a ring 3, 3 '. In this packing box, a two-level floor 5 is housed so as to be movable up and down. A technique for storing the two-tiered floor in the packing box so that it can be raised and lowered has been conventionally known, and since it is out of the scope of the present invention, description thereof will be omitted. The locking device that fixes and supports the two-tiered floor in the desired position in the packing box can be performed from the previous one, but in order to provide the stage function to this packing box, a locking device that does not interfere with the packing box. Such a locking device is described below.
[0023]
As shown in FIG. 1, when the two-tiered floor is fixed and supported at a predetermined position, it is possible to carry in the luggage appropriately, thereby effectively utilizing the space in the cargo box. In FIG. 1, as shown by a two-dot broken line, when the two-tier floor is arranged at the lowest position, the two-tier floor can also function as a part of the stage.

In this embodiment, the stage unit 6 is pivotally attached to the packing box 1, but it may be detachably attached to the packing box (in this case, the stage unit 6 may be carried into the packing box, or Will be carried separately).
[0028]
In addition, although a packing box having a wing-type roof is taken as an example , a packing box whose side can be opened and closed by a stage portion can be used instead of a wing roof. Even in this case, the attachment point of the stage portion is set to the same plane when the second floor is located at the lowest position.
[0029]
As described above, the two-tiered floor is housed in the packing box according to the prior art so as to be movable up and down, and can be fixed at a predetermined position by the locking device of the prior art. In order to use the floor in the packing box more effectively, it is not desirable that the locking device be in the way.

FIG. 7 shows an example in which the frame material for raising and lowering and the frame material for the lock device are provided side by side.
[0035]
The frame member 30 is configured by joining side surfaces of a frame member 30a of the locking device and a frame member 30b for raising and lowering. The frame member 30a (same as the frame member 30b) has a frame member rear wall 31, and both side surfaces 32 and 33 on which the top portion 22 and the bottom portion 23 of the stopper portion can be disposed, and further projects inward from the side surfaces. Overhangs 32 'and 33' are provided. In this embodiment, each of the overhanging portions projects inward, so that the space between the overhanging portions is substantially equal to the width of the top portion 22 and the bottom portion 23 of the stopper portion.
[0036]
The frame material rear wall 31 has two pairs of through-holes 34 and 35 through which the tips curved below the top portion 22 and the bottom portion 23 of the stopper portion can pass in a state where the stopper portion is horizontal. The second floor is opened at a position for positioning it at a desired position (FIG. 7B).
[0037]
Since the tips of the top portion 22 and the bottom portion 23 of the stopper portion are curved, as shown in FIG. 8, when the stopper portion is attached to the frame member, it is between the tip portion and the rear wall of the frame member. The auxiliary protrusions 36 and 37 are fixed to the back surface of the back wall of the frame member so that no gap is generated. Therefore, the auxiliary projection is provided below each hole.
[0038]
Further, as shown in more detail in FIG. 5, when the stopper portion is attached to the frame member and the lower surfaces of the top portion 22 and the bottom portion 23 are brought into contact with the lower edge of the hole, the protruding portions 24 and 25 of the stopper portion are In contact with the projecting portions 32 ′ and 33 ′ of the frame member, stop pieces 41 and 42 for supporting the projecting portions 24 and 25 from below are provided on the projecting portions 32 ′ and 33 ′, respectively.
[0039]
The locking operation of the locking device will be described with reference to the drawings.
As shown in FIG. 8 (A), the second floor 5 is positioned slightly above a predetermined position, and as shown in FIG. 5, the stopper portion 20 is brought closer to the frame member 30, As shown in Fig. 8 (A), insert between both side walls. Subsequently, as shown in FIG. 8B, the curved tips of the top portion 22 and the bottom portion 23 of the stopper portion 20 are inserted into the through holes 34 and 35 of the frame member, respectively, and the auxiliary pieces 26 and 27 are inserted. The end surface of the frame is in contact with the surface of the back surface portion 31 of the frame member. Further, in this state, the stopper portion 20 is lowered.
[0040]
As shown in FIG. 8 (C), when the stopper portion 20 is lowered and the lower surfaces of the top portion 22 and the bottom portion 23 are in contact with the lower edges of the through holes 34 and 35, the top portion 22 and the bottom portion 23 are below the tips. The side is in contact with the auxiliary protrusions 36 and 37, and the protruding portions 24 and 25 of the stopper portion 20 are in contact with the stop pieces 32 'and 33' and supported by the stop pieces 41 and 42 from below.
[0041]
In this state, the second floor 5 descends and comes into contact with the top 22 of the stopper portion 20, so that the second floor is supported from below, and is thus fixed and supported at an arbitrary position. Although the above description is about the attachment of the stopper portion for one frame material, the same applies to the attachment to other frame materials. The stopper portion can be easily removed by reversing the attachment operation.
[0042]
The frame material shown in FIGS. 5 and 7 serves as both the frame material constituting the locking device and the guide frame material in which the slide block for raising and lowering the two-step floor is accommodated. It is also possible to provide them separately in the packing box.
[0043]
The protruding part of the stopper part protrudes from both ends of the back part, but depending on the weight and size of the two-tiered floor, only one of them functions. At this time, the stop piece becomes one corresponding to this.
[0044]
As described above, when the frame member 30 is provided separately, the protruding portions 32 ′ and 33 ′ of the frame member may protrude outward rather than inward.
[0045]
The tips of the top 22 and bottom 23 of the stopper shown in the figure are curved and bent downward, but when bent at a substantially right angle, the inside of the tip is not spaced from the back of the rear wall of the frame material. Since the contact can be made, the auxiliary protrusion is not necessary.
[0046]
As above, the locking device is very compact, substantially occupy the space within packing box. Therefore, when carrying a load using the dual bed are also when using the packing boxes as a stage also, not intended disturbing.
[0047]
【effect】

[0048]
In addition, when the second floor is fixed and supported at a predetermined position, the space in the packing box can be effectively used for loading the luggage into the packing box.
[0049]
Furthermore, according to the present invention, the use of the locking device enables the two-tier floor to be fixed and supported at a predetermined position. Can be used effectively.
[0050]
Furthermore, according to the present invention, when the locking device is used, the locking device does not substantially occupy the space in the packing box, so that the locking device can be used both when using a two-level floor and when using the packing box as a stage. The device does not hinder its use.
