Description

この発明は、不使用時には折り畳んで運搬出来たり、保管できる折り畳み可能な運搬用棚台車に関する。  The present invention relates to a foldable transporting cart that can be folded and transported when not in use.

底板に支柱や柵を立て、その支柱や棚に複数枚の棚板を固定してなる運搬用台車は、物品の保管、運搬に多用されている。これらの運搬用台車は立体的であるので、不使用時には場所を取る不便がある。また運搬用台車の棚に物品を収容して運搬した後、空になった運搬用台車をそのまま運ぶのは、これまた場所を取り不便である。そのため従来から折り畳み可能な運搬用台車が種々提案されている。例えば上に凸になるように折り畳めるキャスター付き固定板に前柵と後柵を立て、前柵と後柵の間に着脱可能な中間柵を設けた運搬用台車が提案されている(特許文献1)。この運搬用台車は、不使用時には中間柵を取り外し、この取り外した中間棚板を前柵の上部に設けた突起に重ねて掛止めし、固定底板を折り曲げ畳むものである。

Description of the Related Art A transport cart in which a support and a fence are set up on a bottom plate and a plurality of shelves are fixed to the support and shelf is often used for storing and transporting articles. Since these transport carts are three-dimensional, there is an inconvenience of taking up space when not in use. In addition, it is inconvenient to take an empty transport cart as it is after transporting an article on a shelf of the transport cart. For this reason, various folding carts that can be folded have been proposed. For example, a transport cart has been proposed in which a front fence and a rear fence are set up on a fixed plate with casters that can be folded upward so that a removable intermediate fence is provided between the front fence and the rear fence (Patent Document 1). ). When the carriage is not in use, the intermediate fence is removed, the removed intermediate shelf board is overlapped and hooked on a projection provided on the upper part of the front fence, and the fixed bottom board is folded.
Japanese Patent Laid-Open No. 9-272442

本発明は簡単な構造で、折り畳む操作、作業、また使用状態にする操作、作業が簡単な折り畳み可能な運搬用棚台車を提供することを目的とする。  It is an object of the present invention to provide a foldable transporting cart with a simple structure, which can be folded and operated, operated and used, and easily operated.

本発明は1枚又は複数枚の四角形の棚板と、各棚板の左右両側面の前端部及び後端部を挟むそれぞれ一枚の支柱間にパイプ又は棒状のものを渡して繋ぎ止め、各棚板の両端は、このパイプ又は棒状のものと接触箇所で間隙を設けて回動自在に結合され、且つ棚板の中央部を上方向へは回動するが、下方向へは回動することが出来ない蝶番などによる結合部を設け、各支柱の下端、接地面にキャスターを装着したものである。また、各支柱を、複数本の支柱と着脱自在に挿嵌してつないだ構造にしてもよい。また折り畳み可能な運搬用棚台車の両側面の棚板の中央部に縦方向の、また、支柱間にたすき掛けの線状の補強材を装着するのが好ましい。  In the present invention, one or a plurality of rectangular shelf boards and a pipe or a rod-like object are connected and secured between each of the support pillars sandwiching the front end part and the rear end part of the left and right side surfaces of each shelf board, Both ends of the shelf board are connected to the pipe or the rod-like object with a gap at a contact point so as to be rotatable, and the central part of the shelf board is rotated upward, but is rotated downward. A connecting part such as a hinge that cannot be used is provided, and a caster is attached to the lower end of each column and the grounding surface. Moreover, each strut may have a structure in which a plurality of struts are detachably inserted. Further, it is preferable to install a vertical reinforcing member in the center of the shelf plate on both side surfaces of the foldable transporting shelves and between the columns.

本発明の折り畳み可能な運搬用棚台車は、構造が簡単である。不使用時には棚板の中央部より折り畳み重ねるようして平面的になる。すなわち簡便に平面的に折り畳める。そのため、運搬用棚台車を保管するときや運搬するときに場所を取らず便利である。また使用に当たっては上記の逆に操作して、各棚板を横方向へ広げ延ばすようにして、水平にし、簡単な操作で使用状態にすることが出来る。また固定枠体、補強材を備えさせることによって、使用時に運搬用棚台車が歪むのを防ぐことが出来る。そして本発明の通常の運搬用棚台車の用途に用いることが出来るが、例えば苗床や花弁などの運搬に有利である。  The foldable transport cart of the present invention has a simple structure. When not in use, it becomes flat so that it can be folded over from the center of the shelf. That is, it can be simply folded in a plane. Therefore, it is convenient not to take a place when storing or transporting the transporting cart. In use, it is possible to operate in the reverse manner as described above so that each shelf board is spread and extended in the horizontal direction so that it is level and can be used in a simple operation. Further, by providing the fixed frame body and the reinforcing material, it is possible to prevent the transporting cart from being distorted during use. And although it can be used for the use of the normal carrying shelf cart of this invention, it is advantageous for conveyance of a nursery, a petal, etc., for example.
