Japanese Patent Laid-Open No. 11-5540

而して、特許文献１に記載のように、従来の荷役用台車の内装カバーでは、ベースシート部は、単にベースの上に重ねられているだけであって、台車の折り畳みに際しても、台車の折り畳み操作とは先行して、ベースシート部を含む内装カバー全体を折り畳み、その後、台車側のベースとサイドパネルの片側とを折り畳む操作を行う必要があり、内装カバーの折り畳みに手間がかかるという問題点があった。勿論、このような問題点を解決するためにベースとベースシート部とを連結一体化することも考えられるが、ベースシート部は、鉄板などから構成されるものではなく、一般的には厚手の布状物となるものであるから、このようなベースシート部を紐状体や面ファスナー付きベルトなどの緊締具でベースに締結する方法では、ベースシート部の緊締具取付け箇所に応力が集中して破れるなどの損傷を来たす恐れが大きく、耐用寿命が短くなる問題点が生じる。 Thus, as described in Patent Document 1, in the conventional interior cover of a cargo handling cart, the base sheet portion is simply overlaid on the base, and even when the cart is folded, Prior to the folding operation, it is necessary to fold the entire interior cover including the base seat part, and then to fold the base on the cart side and one side of the side panel, which is troublesome to fold the interior cover. There was a point. Of course, in order to solve such problems, it is conceivable to connect and integrate the base and the base sheet portion, but the base sheet portion is not composed of an iron plate or the like, and is generally thick. Since the base sheet is fastened to the base with a fastener such as a string-like body or a belt with a hook-and-loop fastener, the stress concentrates on the location where the fastener is attached to the base sheet. Therefore, there is a risk of damage such as tearing, resulting in a problem that the service life is shortened.

本発明は上記のような従来の問題点を解消し得る荷役用台車の内装カバーを提供することを目的とするものであって、請求項１に記載の荷役用台車の内装カバーは、後述する実施形態の参照符号を付して示すと、折り畳み可能な荷役用台車１に取り付けられる内装カバー９であって、前記荷役用台車１は、バックパネル２、このバックパネル２の内側に重なる起立姿勢に折り畳み可能なベース３、及びバックパネル２の左右両側辺から直角前方に延出する左右一対のサイドパネル４，５を備え、両サイドパネル４，５の内、一方のサイドパネル５は、起立姿勢のベース３に重なる折り畳み姿勢に切換えられるようにバックパネル２に対して開閉自在に連結され、前記内装カバー９は、バックパネル２の内側に沿うバックシート部１０、左右両サイドパネル４，５の内側に沿うサイドシート部１１，１２、バックシート部１０の下側辺から連設されてベース３の上に重なるベースシート部１６、及びベースシート部１６をベース３に固定するベース連結手段４５を備え、このベース連結手段４５は、ベースシート部１６の底面に取り付けられた硬質薄板材４８ａ，４８ｂとこの硬質薄板材４８ａ，４８ｂに取り付けられたベース緊締具（面ファスナー付きベルト２２ａ，２２ｂ）とから成る構成となっている。 The object of the present invention is to provide an interior cover for a cargo trolley that can solve the above-mentioned conventional problems. The interior cover for a cargo trolley according to claim 1 will be described later. An embodiment of the present invention will be described with reference to the embodiment. The interior cover 9 is attached to a foldable cargo handling cart 1, and the cargo handling cart 1 has a back panel 2 and a standing posture that overlaps the inside of the back panel 2. 2 and a pair of left and right side panels 4 and 5 that extend forward from the left and right sides of the back panel 2 at right angles, and one of the side panels 4 and 5 is standing upright. The interior cover 9 is connected to the back panel 2 so as to be able to be switched to a folded posture that overlaps the base 3 of the posture. The side sheet parts 11 and 12 along the inside of the id panels 4 and 5, the base sheet part 16 that is provided continuously from the lower side of the back sheet part 10 and overlaps the base 3, and the base sheet part 16 is fixed to the base 3. The base connection means 45 includes a hard thin plate material 48a, 48b attached to the bottom surface of the base sheet portion 16, and a base fastener (a belt with a hook-and-loop fastener) attached to the hard thin plate material 48a, 48b. 22a, 22b).

上記構成の本発明を実施するについて、具体的には請求項２に記載のように、前記ベースシート部１６には、その略全面にわたって硬質合成樹脂の薄板材４４を添着（ベースシート部１６を構成する２枚のシート材の間にサンドイッチにしても良いし、ベースシート部１６の表面上又は底面下に露出させて敷設しても良い）して、ベースシート部１６の全体に適当な硬さを持たせることができる。この硬質合成樹脂の薄板材４４をベースシート部１６の底面下に露出させて敷設する場合は、この硬質合成樹脂の薄板材４４を、ベース緊締具（面ファスナー付きベルト２２ａ，２２ｂ）を取り付けるためにベースシート部１６の底面側に取り付けられる硬質薄板材４８ａ，４８ｂに兼用させることも可能である。 In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, a hard synthetic resin thin plate material 44 is attached to the base sheet portion 16 over substantially the entire surface (the base sheet portion 16 is attached). A sandwich may be provided between the two sheets of the material, or the base sheet portion 16 may be exposed and laid on the surface or under the bottom surface of the base sheet portion 16). It can have a thickness. When the hard synthetic resin thin plate material 44 is exposed and laid under the bottom surface of the base sheet portion 16, the hard synthetic resin thin plate material 44 is attached to the base fasteners (belts 22a and 22b with hook-and-loop fasteners). It is also possible to use the hard thin plates 48a and 48b attached to the bottom surface side of the base sheet portion 16.

又、請求項３に記載のように、前記硬質薄板材４８ａ，４８ｂには、紐又はベルト状のベース緊締具（面ファスナー付きベルト２２ａ，２２ｂなど）が着脱自在に挿通される孔４９を設けることができる。この場合には、請求項４に記載のように、前記紐又はベルト状のベース緊締具（面ファスナー付きベルト２２ａ，２２ｂなど）を挿通させるための孔４９，５０は、位置を変えて複数個所に設けることができる。 According to a third aspect of the present invention, the hard thin plate members 48a and 48b are provided with holes 49 through which strings or belt-like base fasteners (such as belts 22a and 22b with hook-and-loop fasteners) are detachably inserted. be able to. In this case, as described in claim 4, the holes 49 and 50 through which the string or belt-like base fasteners (the belts 22a and 22b with hook-and-loop fasteners, etc.) are inserted have a plurality of positions. Can be provided.

又、請求項５に記載のように、前記硬質薄板材４８ａ，４８ｂは、その一側辺のみをベースシート部１６の前側辺に縫合することができるし、請求項６に記載のように、前記硬質薄板材４８ａ，４８ｂは左右一対取り付けて、各硬質薄板材４８ａ，４８ｂにベース緊締具（面ファスナー付きベルト２２ａ，２２ｂなど）を取り付けることができる。 Further, as described in claim 5, the hard thin plate members 48a and 48b can be stitched to the front side of the base sheet portion 16 only on one side thereof, and as described in claim 6, A pair of left and right hard thin plate members 48a and 48b can be attached, and base tightening tools (such as belts 22a and 22b with hook-and-loop fasteners) can be attached to the respective hard thin plate members 48a and 48b.

更に、請求項７に記載のように、前記ベースシート部１６と一体にベース３が起立姿勢に折り畳まれた状態において、ベースシート部１６とバックシート部１０の内側面とを連結するベースシート部係止手段４６を設けることができる。この場合、請求項８に記載のように、前記ベースシート部係止手段４６は、ベースシート部１６の前側辺に取り付けられた左右方向フラップ部５１と、バックシート部１０の内側面に一側辺が取り付けられた係止片５２と、この左右方向フラップ部５１と係止片５２とに互いに接合剥離自在に取り付けられた面ファスナー５３ａ，５３ｂから構成することができる。 Furthermore, as described in claim 7, in the state where the base 3 is folded in an upright posture integrally with the base sheet portion 16, the base sheet portion that connects the base sheet portion 16 and the inner surface of the back seat portion 10. Locking means 46 can be provided. In this case, as described in claim 8, the base sheet portion locking means 46 has one side on the left and right direction flap portions 51 attached to the front side of the base sheet portion 16 and the inner surface of the back seat portion 10. It can be comprised from the latching piece 52 to which the edge | side was attached, and the hook-and-loop fastener 53a, 53b attached to this left-right direction flap part 51 and the latching piece 52 so that joining and peeling were possible mutually.

請求項１に記載の本発明に係る荷役用台車の内装カバーによれば、ベースシート部がベースに連結されて一体化されているので、ベースを起立姿勢に折り畳むだけで、ベースシート部をバックシート部の内側に重ねるように折り畳むことができ、このベースシート部の折り畳み状態をベースが起立姿勢にある限り保持される。従って、従来のようにベースとベースシート部とが離れているためにベースの折り畳みとベースシート部の折り畳みとを別々に行わなければ成らない場合と比較して折り畳みの操作性が高められる。しかも、本発明の構成によれば、紐状体や面ファスナー付きベルトなどの簡易な緊締具を利用することができるにもかかわらず、当該緊締具が直接ベースシート部に取り付けられるのではなく、ベースシート部の底面に取り付けられた硬質薄板材に緊締具が取り付けられる構成であるから、当該緊締具でベースシート部をベースに取り付けるときの緊締力を硬質薄板材で受け止めさせ、当該緊締力をベースシート部に対し局部的に作用させる恐れがない。従って、ベースに対するベースシート部の取付け取り外しが繰り返されたとしても、ベースシート部が局部的に破れるなどの損傷を受けることがなくなり、耐用寿命も永くなる。 According to the interior cover of the cargo trolley according to the first aspect of the present invention, since the base seat portion is connected and integrated with the base, the base seat portion can be backed only by folding the base seat in an upright position. The base sheet portion can be folded so as to overlap the inside of the seat portion, and the folded state of the base seat portion is maintained as long as the base is in the standing posture. Therefore, since the base and the base sheet portion are separated from each other as in the prior art, the operability of the folding is improved as compared with the case where the folding of the base and the folding of the base sheet portion must be performed separately. Moreover, according to the configuration of the present invention, although a simple fastener such as a string-like body or a belt with a hook-and-loop fastener can be used, the fastener is not directly attached to the base sheet portion, Since the tightening tool is attached to the hard thin plate material attached to the bottom surface of the base sheet portion, the tightening force when the base sheet portion is attached to the base with the tightening tool is received by the hard thin plate material, and the tightening force is received. There is no fear of acting locally on the base sheet. Therefore, even if the base sheet portion is repeatedly attached to and detached from the base, the base sheet portion is not damaged such as being locally broken, and the service life is prolonged.

尚、請求項２に記載の構成によれば、ベースシート部の略全面にわたって添着された硬質合成樹脂の薄板材によってベースシート部全体に適当な硬さを持たせることができるので、仮に１つのベース緊締具でこのベースシート部をベースに取り付ける場合であっても、ベースシート部の略全面を平らに緊張した状態に保持させることができるので、荷との摺接などによる損傷も抑制できる。勿論、この硬質合成樹脂の薄板材をベースシート部の表面に露出させて取り付けるときは、ベースシート部表面の耐磨耗性を高めることができ、ベースシート部上を滑らせて荷の出し入れを容易に行うこともできる。又、逆に、硬質合成樹脂の薄板材をベースシート部の底面に露出させて取り付けるときは、この硬質合成樹脂の薄板材で、ベース緊締具を取り付けるためにベースシート部の底面に取り付けられる硬質薄板材に兼用させることも可能である。 In addition, according to the structure of Claim 2, since it can give appropriate hardness to the whole base sheet part with the thin board | plate material of the hard synthetic resin affixed over the substantially whole surface of the base sheet part, one provisionally Even when the base sheet portion is attached to the base with the base tightening tool, the entire surface of the base sheet portion can be held in a flat and tensioned state, so that damage due to sliding contact with the load can be suppressed. Of course, when this thin sheet of hard synthetic resin is mounted exposed on the surface of the base sheet part, the wear resistance of the surface of the base sheet part can be increased, and the load on the base sheet part can be slid. It can also be done easily. Conversely, when mounting a hard synthetic resin thin plate material exposed on the bottom surface of the base sheet portion, the hard synthetic resin thin plate material is attached to the bottom surface of the base sheet portion for mounting a base fastener. It can also be used as a thin plate material.

又、請求項３に記載の構成によれば、簡易な紐又はベルト状のベース緊締具が利用できるだけでなく、これらベース緊締具の劣化状況に応じて簡単に取り替えることができ、長期間にわたって容易に活用できる。この場合、請求項４に記載の構成によれば、ベースの構造が異なる（例えばメッシュ構造であっても網目の配列やサイズが異なる）別の荷役用台車にこの内装カバーを取り付ける場合でも、紐又はベルト状のベース緊締具を挿通させる孔の位置を選択するだけで、支障なくベースシート部をベースに取り付けることができ、この内装カバーの汎用性を高めることができる。 Further, according to the configuration of claim 3, not only a simple string or belt-like base fastener can be used, but also can be easily replaced according to the deterioration status of these base fasteners, and it can be easily used for a long time. Can be used for In this case, according to the configuration of the fourth aspect, even when the interior cover is attached to another cargo handling cart having a different base structure (for example, a mesh structure and a different mesh arrangement and size) Alternatively, the base sheet portion can be attached to the base without hindrance only by selecting the position of the hole through which the belt-like base fastener is inserted, and the versatility of the interior cover can be enhanced.

ベース緊締具を取り付けるための硬質薄板材は、サイズや形状、ベースシート部への取付け構造などが限定されるものではない。例えば、ベースシート部への取付け構造については、その周縁部全域をベースシート部に縫合することもできるし、接着剤により取り付けることも、接着剤と縫合との併用で取り付けることもできるが、特に請求項５に記載の構成によれば、ベースシート部を縫製する場合に当然必要な周縁部の縫合に際して前記硬質薄板材を同時に取り付けることができ、ベース緊締具を取り付けるための硬質薄板材の追加による製造のコストアップを抑制できる。しかも一側辺がベースシート部の底面の前側辺に縫合された硬質薄板材は、その縫合された一側辺とは反対側の側辺をベースシート部から離すように操作することができ、この硬質薄板材に設けられた孔に紐又はベルト状のベース緊締具を着脱自在に挿通させる構成の採用が極めて容易になる。 The hard thin plate material for attaching the base fastener is not limited in size, shape, attachment structure to the base sheet portion, or the like. For example, regarding the attachment structure to the base sheet part, the entire peripheral edge part can be sewn to the base sheet part, and it can be attached with an adhesive or a combination of an adhesive and stitching, According to the configuration of the fifth aspect, the hard thin plate material can be attached at the same time when the peripheral edge portion is naturally sewn when the base sheet portion is sewn, and the addition of the hard thin plate material for attaching the base fastener It is possible to suppress the manufacturing cost increase due to the above. Moreover, the hard thin plate material with one side stitched to the front side of the bottom surface of the base sheet portion can be operated so that the side opposite to the stitched one side is separated from the base sheet portion, It is very easy to adopt a configuration in which a string or belt-like base fastener is detachably inserted into a hole provided in the hard thin plate material.

又、ベースシート部は、その左右２箇所でそれぞれベース緊締具によりベースに取り付けるのが理想的であるが、この場合、１枚の大きなサイズの硬質薄板材をベースシート部の底面の略全幅にわたって取り付け、この硬質薄板材の左右方向の２箇所にそれぞれベース緊締具を取り付ける場合よりも、請求項６に記載の構成によれば、使用する硬質薄板材全体の材量を少なくし得ると共に、請求項５に記載の構成を採用する場合に、ベース緊締具ごとに硬質薄板材をベースシート部に対して動かせるので、例えば請求項３に記載の構成によるベース緊締具の取替えや、請求項４に記載の構成によるベース緊締具の取付け位置の変更などが容易に行える。 Ideally, the base sheet portion is attached to the base with base fasteners at two locations on the right and left sides. In this case, a single large-sized hard thin plate material is applied over substantially the entire width of the bottom surface of the base sheet portion. According to the configuration of claim 6, the amount of the entire hard thin plate material to be used can be reduced, compared to the case where the base fastener is attached to each of two places in the left and right direction of the hard thin plate material. In the case of adopting the configuration according to item 5, since the hard thin plate material can be moved with respect to the base sheet portion for each base fastener, for example, replacement of the base fastener with the configuration according to claim 3 or It is possible to easily change the mounting position of the base fastener with the configuration described.

更に、請求項７に記載の構成によれば、ベースと一体になっているベースシート部とベースシート部係止手段とにより、ベースを起立姿勢に折り畳まれた状態で保持させることができるので、一般的にこの種の荷役用台車が備えている、起立姿勢でベースを自動係止するベース保持手段を、内装カバーの存在により機能させることができないような場合でも、片側のサイドパネルを折り畳むときに片手でベースを起立姿勢に保持しておく必要がないし、このサイドパネルを開いたときにベースが突然に手前に回倒するような危険な事態が生じるのを防止できる。この場合、請求項８に記載の構成によれば、安価に実施できる簡単な構成でありながら、ベースシート部側の左右方向フラップ部とバックシート部側の係止片とを重ねて押し付けるだけの極めて簡単な操作により、ベースを起立姿勢で強固に保持することができる。 Furthermore, according to the structure of Claim 7, since the base can be hold | maintained by the state folded by the base sheet part and the base sheet part latching means integrated with the base in the standing posture, Even when folding the side panel on one side, even if the base holding means that automatically holds the base in a standing posture cannot be operated due to the presence of the interior cover, this type of cargo handling cart is generally equipped Therefore, it is not necessary to hold the base in an upright posture with one hand, and it is possible to prevent a dangerous situation in which the base suddenly falls forward when the side panel is opened. In this case, according to the configuration described in claim 8, while being a simple configuration that can be implemented at low cost, the left-right flap portion on the base sheet portion side and the locking piece on the back seat portion side are simply pressed against each other. The base can be firmly held in an upright posture by an extremely simple operation.

以下に本発明の具体的実施例を添付図に基づいて説明すると、図１及び図２に示す折り畳み可能な荷役用台車１は、従来周知のもので、バックパネル２、このバックパネル２の下側辺に上下起伏自在に後側辺が軸支されたベース３、バックパネル２の左右両側辺から直角前方向きに延出する左右一対のサイドパネル４，５、及びこの左右両サイドパネル４，５の下側辺の前後両端下側に取付け座６ａを介して取り付けられた車輪６から構成され、向かって右側のサイドパネル５は、バックパネル２の内側に重なる折り畳み姿勢とバックパネル２に対し直角前方向きの使用姿勢との間で水平開閉自在にバックパネル２の側辺に連結されている。そしてこの荷役用台車１は、使用しないとき、ベース３をバックパネル２の内側に沿って起立する起立姿勢に折り畳んだ状態で右側サイドパネル５を内側へ水平に閉動させ、図２に示すように、当該右側サイドパネル５とバックパネル２との間で起立姿勢のベース３を挟みこんだ、平面視でＬ形に折り畳むことができるものであるが、前記ベース３には、起立姿勢でこのベース３を保持させるためのベース保持手段７が設けられている。 A specific embodiment of the present invention will be described below with reference to the accompanying drawings. The foldable cargo handling cart 1 shown in FIGS. 1 and 2 is a well-known conventional one, and includes a back panel 2 and a bottom of the back panel 2. A base 3 whose rear side is pivotally supported up and down on the side, a pair of left and right side panels 4 and 5 extending from the left and right sides of the back panel 2 toward the front at right angles, and both the left and right side panels 4 5 is composed of wheels 6 attached to the lower sides of the lower side of the front and rear ends via attachment seats 6a, and the right side panel 5 faces the folding position and the back panel 2 overlapping the inner side of the back panel 2. It is connected to the side of the back panel 2 so as to be horizontally openable and closable with a right-angled forward use posture. When the cargo handling cart 1 is not in use, the right side panel 5 is horizontally moved inward in a state where the base 3 is folded in an upright posture along the inside of the back panel 2, as shown in FIG. Further, the base 3 in an upright position is sandwiched between the right side panel 5 and the back panel 2 and can be folded into an L shape in a plan view. Base holding means 7 for holding the base 3 is provided.

ベース保持手段７としては、図２Ａ，Ｂに示すように、ベース３の側辺に弾性に抗して退入可能に設けられた半球面状の突起部８ａを備えたものや、図２Ｃに示すように、ベース３の側辺から突出する出退操作可能なピン状の突起部８ｂを備えたものなどが知られている。前者の半球面状の突起部８ａを備えたベース保持手段７では、図２Ａに示すように、ベース３の左右両側辺の内、バックパネル２との間の間隔が広くなっている開閉自在な右側サイドパネル５に隣接する側の側辺にのみ突起部８ａが設けられ、後者の出退操作可能なピン状の突起部８ｂを備えたベース保持手段７は、ベース３が左右両サイドパネル４，５の下側辺で支持される使用姿勢（水平倒伏姿勢）において、当該ベース３を左右両サイドパネル４，５の下側辺に係合させる手段も兼用するもので、ベース３の左右両側辺に出退操作可能なピン状の突起部８ｂが設けられ、ベース３の前側辺に設けられた操作具により左右一対のピン状の突起部８ｂを同時に出退操作できるように構成される。 As shown in FIGS. 2A and 2B, the base holding means 7 includes a hemispherical protrusion 8a provided on the side of the base 3 so as to be retractable against elasticity. As shown in the figure, there is known one having a pin-like protrusion 8b protruding from the side of the base 3 and capable of being withdrawn / retracted. In the base holding means 7 having the former hemispherical projection 8a, as shown in FIG. 2A, the space between the back panel 2 and the left and right sides of the base 3 is wide. The base holding means 7 is provided with a protrusion 8a only on the side adjacent to the right side panel 5, and the latter is provided with a pin-like protrusion 8b that can be moved in and out. , 5 is also used as a means for engaging the base 3 with the lower sides of the left and right side panels 4, 5 in the use posture (horizontal lying posture) supported by the lower side of the base 3. A pin-shaped protrusion 8b that can be operated to be withdrawn / retracted from the side is provided, and a pair of left and right pin-shaped protrusions 8b can be operated at the same time by an operation tool provided on the front side of the base 3.

而して、半球面状の突起部８ａを備えたベース保持手段７では、ベース３を起立姿勢に折り畳んだとき、その直前のサイドパネル５の後側辺の垂直枠部５ｃ横を通過するときに当該垂直枠部５ｃにより弾性に抗して退入動作した突起部８ａが、サイドパネル５の後側辺とその後側のバックパネル２の側辺との間に弾性復帰により嵌まり込むことにより、ベース３を起立姿勢に保持するものであり、ベース３を水平の使用姿勢に回倒させるときは、ベース３を強く手前に倒せば良い。一方、出退操作可能なピン状の突起部８ｂを備えたベース保持手段７では、左右一対の突起部８ｂを操作具で退入させた状態でベース３を起立姿勢に折り畳み、その後、操作具を戻して左右一対の突起部８ｂを進出させ、左右両サイドパネル４，５の後側辺とその後側のバックパネル２の側辺との間に嵌まり込ませることにより、ベース３を起立姿勢に保持するものであり、ベース３を水平の使用姿勢に回倒させるときは、その前に操作具で左右一対の突起部８ｂを退入させる。 Thus, in the base holding means 7 having the hemispherical projection 8a, when the base 3 is folded in the standing posture, when passing the side of the vertical frame 5c on the rear side of the side panel 5 immediately before it. In addition, the protrusion 8a that retreats against the elasticity by the vertical frame portion 5c is fitted between the rear side of the side panel 5 and the side of the back panel 2 on the rear side by elastic return. The base 3 is held in a standing posture, and when the base 3 is turned down to a horizontal use posture, the base 3 may be strongly pushed forward.

以上のように構成された内装カバー９の取付け方法を、図１、図３及び図１１〜図１５を参照して説明すると、図１に示すように組み立てられた荷役用台車１のバックパネル２の内側にバックシート部１０を沿わせるように配置し、その上側辺を面ファスナー付きベルト１７ａ，１７ｂによりバックパネル２の上端水平枠部２ａに結合する。左右両サイドパネル４，５の内側に沿って垂下させた左右両サイドシート部１１，１２は、その上側辺を面ファスナー付きベルト１８ａ，１８ｂにより左右両サイドパネル４，５の上端水平枠部４ａ，５ａに結合すると共に、前後両側辺の中間高さ位置にある面ファスナー付きベルト１９ａ，１９ｂ及び２０ａ，２０ｂにより左右両サイドパネル４，５の前後両端の垂直枠部４ｂ，４ｃ及び５ｂ，５ｃに結合する。次にベース３上に載置させたベースシート部１６を２本の面ファスナー付きベルト２２ａ，２２ｂにより、図９に基づいて説明した要領でベース３に結合する。 A method of attaching the interior cover 9 configured as described above will be described with reference to FIGS. 1, 3, and 11 to 15. The back panel 2 of the cargo handling cart 1 assembled as shown in FIG. The back sheet portion 10 is arranged along the inner side, and the upper side thereof is coupled to the upper end horizontal frame portion 2a of the back panel 2 by means of belts 17a and 17b with hook-and-loop fasteners. The left and right side seat portions 11 and 12 suspended along the inner sides of the left and right side panels 4 and 5 have upper side horizontal frames 4a of the left and right side panels 4 and 5 at their upper sides by belt fasteners 18a and 18b with hook-and-loop fasteners. , 5a and the vertical frame portions 4b, 4c and 5b, 5c at the front and rear ends of the left and right side panels 4, 5 by the belt fasteners 19a, 19b and 20a, 20b at the intermediate height positions on both the front and rear sides. To join. Next, the base sheet portion 16 placed on the base 3 is coupled to the base 3 by the two belt fastener-attached belts 22a and 22b as described with reference to FIG.

而して、ベース３が水平使用姿勢において左右両サイドパネル４，５の下側辺で支持され且つ係止されている状態では、バックシート部１０の下半部１０ｂの左右両側辺とベースシート部１６の左右両側辺とにわたって連続するＬ形のフラップユニット２９，３０が垂直姿勢にあるので、この左右両フラップユニット２９，３０の内側に左右両サイドシート部１１，１２の下半部１１ｂ，１２ｂを垂下させると共にその後側辺と下側辺とを内側から左右両フラップユニット２９，３０の側に押し付けて、面ファスナー３４ａ〜３７ｂにより両者の重なり部分を互いに接合する。この後、左右両サイドシート部１１，１２の前側辺の下端近傍位置を面ファスナー付きベルト２１ａ，２１ｂにより左右両サイドパネル４，５の前端側の垂直枠部４ｂ，５ｂに結合する。 Thus, in the state in which the base 3 is supported and locked by the lower sides of the left and right side panels 4 and 5 in the horizontal use posture, the left and right sides of the lower half 10b of the back seat portion 10 and the base sheet Since the L-shaped flap units 29 and 30 that are continuous over the left and right sides of the portion 16 are in a vertical posture, the lower half portions 11b of the left and right side seat portions 11 and 12 are disposed inside the left and right flap units 29 and 30, respectively. 12b is suspended and the rear side and the lower side are pressed against the left and right flap units 29 and 30 from the inside, and the overlapping portions of the two are joined to each other by the hook-and-loop fasteners 34a to 37b. Thereafter, the positions near the lower ends of the front side edges of the left and right side seat portions 11, 12 are joined to the vertical frame portions 4b, 5b on the front end sides of the left and right side panels 4, 5 by means of belts 21a, 21b with hook-and-loop fasteners.

上記の取付け作業中の各面ファスナー付きベルト１７ａ〜２１ｂによる緊締作業に際しては、図１０に示すように、面ファスナー付きベルト１７ａ〜２１ｂを各パネル２，４，５側の枠部２ａ，４ａ〜４ｃ，５ａ〜５ｃに内側から巻き付けて遊端側を引っ張り、対面する面ファスナー５５ａ，５５ｂを互いに押し付けて接合するのであるが、このとき摘み舌片５６を反対側の手で保持した状態で面ファスナー付きベルト１７ａ〜２１ｂを強く引っ張ることができ、しかもその引っ張り方向は、各シート部１０〜１２を長さ方向又は幅方向に緊張させる向きとなるので、各シート部１０〜１２を弛みなく取り付けることができる。特に面ファスナー付きベルト１７ａ〜２０ｂは、ベルト遊端側をリング５７に挿通した状態で強力に引っ張ることができる。 As shown in FIG. 10, the belts 17a to 21b with the hook-and-loop fasteners are attached to the frame portions 2a, 4a to the panels 2, 4 and 5 in the fastening operation by the belts 17a to 21b with the hook-and-loop fasteners. 4c, 5a to 5c are wound from the inside, the free end side is pulled, and the surface fasteners 55a, 55b facing each other are pressed and joined to each other, but at this time, the tab tongue piece 56 is held in the state of being held by the opposite hand. The belts 17a to 21b with fasteners can be pulled strongly, and the pulling direction is a direction in which the sheet portions 10 to 12 are tensioned in the length direction or the width direction, so that the sheet portions 10 to 12 are attached without slack. be able to. In particular, the belt fasteners 17 a to 20 b can be pulled strongly with the belt free end side inserted through the ring 57.

以上で荷役用台車１への内装カバー９の取付けが完了するので、ファスナー１３，１４の開動により開閉自在シート部１５を開くことにより、この内装カバー９で囲まれた荷収納空間内に対する荷の出し入れを行い、その後はファスナー１３，１４の閉動により開閉自在シート部１５を閉じ、前記荷収納空間を密閉すれば良い。 Since the attachment of the interior cover 9 to the cargo handling cart 1 is completed as described above, by opening the openable / closable seat portion 15 by opening the fasteners 13 and 14, the load in the load storage space surrounded by the interior cover 9 can be reduced. After that, the openable and closable seat portion 15 is closed by closing the fasteners 13 and 14, and the load storage space is sealed.

荷役用台車１を図２に示すように平面視でＬ形に折り畳む場合の作業方法について、図１１〜図１５に基づいて説明すると、先ず最初に、図１１に示すように、ファスナー１３，１４の開動により開閉自在シート部１５を開き、この開閉自在シート部１５を外巻きに三つ折りにする。このとき、開閉自在シート部１５の谷折り線が補強用細帯状部材２６ａ，２６ｂによって決められているので、この開閉自在シート部１５の三つ折り作業が簡単且つ正確に行えると共に、谷折り線での開閉自在シート部１５の傷みが補強用細帯状部材２６ａ，２６ｂの存在で抑えられ、耐用寿命を永くすることができる。このように外巻き三つ折りにされた開閉自在シート部１５は、開閉自在シート部係止手段４０の係止用ベルト４１と面ファスナー４２ａ，４２ｂとで、バックシート部１０の上側辺、延いてはバックパネル２の上端水平枠部２ａから吊り下げ状態に保持させることができる。 The working method when the cargo handling cart 1 is folded into an L shape in plan view as shown in FIG. 2 will be described with reference to FIGS. 11 to 15. First, as shown in FIG. The openable / closable sheet part 15 is opened by the opening movement, and the openable / closable sheet part 15 is folded into three in an outer winding. At this time, since the valley fold line of the openable / closable sheet portion 15 is determined by the reinforcing strip-like members 26a and 26b, the trifolding operation of the openable / closable sheet portion 15 can be easily and accurately performed. Can be prevented by the presence of the reinforcing strip-like members 26a and 26b, and the service life can be prolonged. The openable / closable sheet portion 15 thus folded in three outer windings extends from the upper side of the backsheet portion 10 by the locking belt 41 and the hook-and-loop fasteners 42a and 42b of the openable / closable sheet portion locking means 40. Can be held in a suspended state from the upper end horizontal frame portion 2a of the back panel 2.

次に左右両サイドシート部１１，１２の前側辺の下端近傍位置を左右両サイドパネル４，５の前端側の垂直枠部４ｂ，５ｂに締結している面ファスナー付きベルト２１ａ，２１ｂを解き、これらサイドシート部１１，１２の下半部１１ｂ，１２ｂの後側辺と下側辺とを、外側のフラップユニット２９，３０から引き剥がすように引っ張って、面ファスナー３４ａ〜３７ｂによる接合を解くことにより、左右両サイドシート部１１，１２の下半部１１ｂ，１２ｂをフリーな状態にする。このとき操作される面ファスナー付きベルト２１ａ，２１ｂには、図１０に示すリング５７が併用されていないので、その開放操作は比較的容易に行える。この後、図１２に示すように、左右両サイドシート部１１，１２の下半部１１ｂ，１２ｂを内側上方に捲り上げて二つ折りにするが、このときもその谷折り線が補強用細帯状部材２４によって決められているので、この左右両サイドシート部１１，１２の二つ折り作業が簡単且つ正確に行えると共に、谷折り線でのサイドシート部１１，１２の傷みが補強用細帯状部材２４の存在で抑えられ、耐用寿命を永くすることができる。 Next, unfasten the belts 21a, 21b with hook-and-loop fasteners that fasten the positions near the lower ends of the front side edges of the left and right side seat portions 11, 12 to the vertical frame portions 4b, 5b on the front end sides of the left and right side panels 4, 5. Pull the rear side and the lower side of the lower half portions 11b, 12b of these side seat portions 11, 12 so as to be peeled off from the outer flap units 29, 30 to release the joining by the hook-and-loop fasteners 34a-37b. Thus, the lower half portions 11b and 12b of the left and right side seat portions 11 and 12 are brought into a free state. Since the ring 57 shown in FIG. 10 is not used in combination with the belt fasteners 21a, 21b operated at this time, the opening operation can be performed relatively easily. Thereafter, as shown in FIG. 12, the lower half portions 11b and 12b of the left and right side seat portions 11 and 12 are rolled up inward and folded into two, and at this time, the valley fold line is in the form of a reinforcing strip. Since it is determined by the member 24, the left and right side sheet portions 11 and 12 can be folded in a simple and accurate manner, and the side sheet portions 11 and 12 are damaged at the valley fold line. It can be suppressed by the presence of, and the service life can be extended.

上記のように内巻き二つ折りにした左右両サイドシート部１１，１２は、係止手段５８の面ファスナー２５ａ，２５ｂによって、当該左右両サイドシート部１１，１２の下側辺内側面を当該サイドシート部１１，１２の内側面所定高さ位置に接合することにより、二つ折り状態に保たせることができる。 The left and right side seat portions 11 and 12 that are folded inward as described above are formed on the lower side inner side surfaces of the left and right side seat portions 11 and 12 by the surface fasteners 25a and 25b of the locking means 58. By joining the inner side surfaces of the sheet portions 11 and 12 at a predetermined height position, the sheet portions 11 and 12 can be kept in a folded state.

この後、図１３及び図１４に示すようにベース３をその上に締結されているベースシート部１６と共に上方後方に回動させて起立姿勢に折り畳むのであるが、このとき左右両フラップユニット２９，３０は、その中間角部の谷折り線３３において内側に閉じるように変形しながらバックシート部１０及びベースシート部１６に対し内側に倒れるので、当該左右両フラップユニット２９，３０の前後奥行き方向フラップ部３１及び上下方向フラップ部３２をバックシート部１０とベースシート部１６との間に挟みこむように、ベース３及びベースシート部１６を起立姿勢に折り畳むことができる。一方、図１３及び図１４に示すように、開閉自在シート部係止手段４０により外巻き三つ折り状態で保持された開閉自在シート部１５の下辺レベルと、係止手段５８により内巻き二つ折り状態で保持された左右両サイドシート部１１，１２の下辺レベルは、起立姿勢になったベース３の上端レベルより高いので、ベース３をベースシート部１６と共に起立姿勢に折り畳む作業に際して、開閉自在シート部１５や左右両サイドシート部１１，１２の存在が影響することは一切なく、ベース３の折り畳み作業は容易に行えるばかりでなく、ベース３の側辺から突出しているベース保持手段７の突起部８ａ(又は８ｂ）が左右両サイドシート部１１，１２と摺接することも無い。 Thereafter, as shown in FIGS. 13 and 14, the base 3 is rotated upward and rearward together with the base sheet portion 16 fastened thereon, and folded into a standing posture. At this time, the left and right flap units 29, 30 falls inward with respect to the back sheet portion 10 and the base sheet portion 16 while being deformed so as to be closed inward at the valley fold line 33 at the intermediate corner portion, so that the front and rear depth direction flaps of the left and right flap units 29, 30 The base 3 and the base sheet part 16 can be folded in an upright position so that the part 31 and the vertical flap part 32 are sandwiched between the back sheet part 10 and the base sheet part 16. On the other hand, as shown in FIG. 13 and FIG. 14, the lower side level of the openable / closable sheet portion 15 held by the openable / closable sheet portion locking means 40 in a state of being folded in the outer winding state, and the inner winding folded state by the locking means 58 Since the lower side level of the left and right side seat parts 11, 12 held by the upper part is higher than the upper end level of the base 3 in the upright position, the openable / closable sheet part when the base 3 is folded together with the base sheet part 16 into the upright position. 15 and the left and right side seat portions 11 and 12 are not affected at all, and the base 3 can be easily folded, and the protruding portion 8a of the base holding means 7 protruding from the side of the base 3 can be used. (Or 8b) does not slidably contact the left and right side seat portions 11, 12.

ベース３をベースシート部１６と共に起立姿勢に折り畳んだとき、当該ベース３と右側サイドパネル５との間には、上記のようにサイドシート部１２が存在しないので、図２に示すように、当該ベース３の右側サイドパネル５側の側辺に設けられたベース保持手段７の半球面状の突起部８ａを右側サイドパネル５の後端側の垂直枠部５ｃの後側に確実に嵌まり込ませて、当該ベース３をして確実に起立姿勢で保持させることができる。この状態で、図１３及び図１４に示すように、ベース連結手段４５の左右方向フラップ部５１と係止片５２とを面ファスナー５３ａ，５３ｂによって接合することにより、起立姿勢に折り畳まれたベース３を更にバックシート部１０にも接合して保持させることができる。勿論、上記の実施形態によれば、左側サイドシート部１１も右側サイドシート部１２と同様に構成されているので、図２Ｃに示すような操作具で出退操作されるピン状の突起部８ｂがベース３の左右両側辺に設けられている荷役用台車においても、起立姿勢に折り畳んだベース３の左右両側辺のピン状の突起部８ｂを左右両サイドパネル４，５の後端側の垂直枠部４ｃ，５ｃの後側に確実に嵌まり込ませて、当該ベース３をして確実に起立姿勢で保持させることができる。 When the base 3 is folded together with the base sheet portion 16 to the upright posture, the side seat portion 12 does not exist between the base 3 and the right side panel 5 as described above. The hemispherical projection 8a of the base holding means 7 provided on the side of the base 3 on the right side panel 5 side is securely fitted to the rear side of the vertical frame 5c on the rear end side of the right side panel 5. Therefore, the base 3 can be securely held in the standing posture. In this state, as shown in FIGS. 13 and 14, the base 3 folded in an upright position by joining the left and right flap portions 51 and the locking pieces 52 of the base connecting means 45 with the hook-and-loop fasteners 53 a and 53 b. Can be further bonded to the back sheet portion 10 and held. Of course, according to the above embodiment, since the left side seat portion 11 is also configured in the same manner as the right side seat portion 12, a pin-like protrusion 8b that is moved out and with the operating tool as shown in FIG. 2C. Even in the cargo handling cart provided on the left and right sides of the base 3, the pin-like protrusions 8b on the left and right sides of the base 3 folded in a standing posture are connected to the rear end sides of the left and right side panels 4 and 5 vertically. The base 3 can be surely fitted in the rear side of the frame portions 4c and 5c, and can be reliably held in the standing posture.

折り畳まれた荷役用台車１を展開して再び使用状態に組み立てるときは、上記の台車折り畳み操作時と逆の手順で、荷役用台車１の展開組立て操作と内装カバー９の展開組立て操作とを行えば良い。又、荷役用台車１から内装カバー９を取り外して保管するときは、面ファスナー付きベルト１７ａ〜２２ｂを解いて内装カバー９を荷役用台車１から取り外し、開閉自在シート部１５の外巻き三つ折り操作と開閉自在シート部係止手段４０による係止操作、左右両サイドシート部１１，１２の下半部１１ｂ，１２ｂの内巻き二つ折り操作と係止手段５８による係止操作、及びバックシート部１０の下半部１０ｂへのベースシート部１６の折り重ね操作とベースシート部係止手段４６による係止操作を順次行った後、バックシート部１０の下半部１０ｂをベースシート部１６と共にバックシート部１０の上半部１０ａの内側に重ねるように折り畳み、この二つ折り状態のバックシート部１０の上に二つ折り状態の左右両サイドシート部１１，１２を重ねるように折り畳むことにより、内装カバー９の全体を、バックシート部１０の上半部１０ａと略同一サイズの扁平状に容易に折り畳むことができる。勿論、先に二つ折り状態の左右両サイドシート部１１，１２をバックシート部１０の上半部１０ａの内側に重ねるように折り畳んだ後、最後にバックシート部１０の下半部１０ｂをベースシート部１６と共にバックシート部１０の上半部１０ａの内側に重ねるように折り畳むこともできる。 When the folded cargo trolley 1 is unfolded and reassembled, the unfolding operation of the cargo trolley 1 and the unfolding and assembling operation of the interior cover 9 are performed in the reverse order of the above-described cart folding operation. Just do it. When the interior cover 9 is removed from the cargo handling cart 1 and stored, the belts 17a to 22b with hook-and-loop fasteners are unfastened to remove the interior cover 9 from the cargo handling cart 1, and the folding operation of the openable / closable seat portion 15 is performed in an outwardly folded manner. And the latching operation by the openable / closable sheet portion locking means 40, the inner half folding operation of the lower half portions 11b and 12b of the left and right side seat portions 11 and 12, the locking operation by the locking means 58, and the backsheet portion 10 After the base sheet portion 16 is folded on the lower half portion 10b and the base sheet portion locking means 46 is sequentially engaged, the lower half portion 10b of the back sheet portion 10 together with the base sheet portion 16 is backsheet. Folded so as to overlap the upper half 10a of the portion 10, and folded into a bi-folded backsheet portion 10 on both right and left side seat portions 11, 1 The by folding to overlap, the entire interior cover 9 can be folded easily on the flat half 10a is substantially the same size on the backsheet portion 10. Of course, after folding the left and right side seat parts 11 and 12 in a folded state so as to overlap the inner side of the upper half part 10a of the back sheet part 10, the lower half part 10b of the back sheet part 10 is finally attached to the base sheet. It can be folded together with the portion 16 so as to overlap the inside of the upper half portion 10a of the backsheet portion 10.

尚、内装カバー９の左右両サイドシート部１１，１２の折り畳みのための構成や開閉自在シート部１５の構成、及び台車側の各パネル２，４，５の内側に沿って位置する各シート部１０〜１２と当該各パネル２，４，５との連結構造は、上記実施形態の構造に限定されない。例えば、左右両サイドシート部１１，１２の折り畳みのための構成は、上記実施形態のものが好ましいが、ベースシート部係止手段４６を併用するときは、ベース保持手段７が機能しなくとも実用上問題はないので、左右両サイドシート部１１，１２の後側辺全域をバックシート部１０の左右両側辺に縫合一体化しても良いし、場合によっては、左右両サイドシート部１１，１２の下側辺、特に折り畳まれない左側サイドパネル４の内側に沿うサイドシート部１１の下側辺を、従来周知のようにベースシート部１６の側辺に縫合一体化しても良い。更に、内装カバーの使用目的によっては、開閉自在シート部１５を持たない内装カバーにも本発明を適用できるし、開閉自在シート部１５を設ける場合でも、当該開閉シート部１５は、左右両サイドシート部１１，１２の前側辺間を塞ぐ領域のみ、開閉自在に構成することもできるし、上記実施形態に示すようにバックシート部１０の上側辺から開閉自在シート部１５の下側辺までの全域を開閉自在に構成している場合において、当該開閉自在シート部１５の正面部分に別の開閉自在な開口部を形成することもできる。 In addition, the structure for folding both the left and right side seat parts 11 and 12 of the interior cover 9, the structure of the openable / closable seat part 15, and the seat parts located along the inside of the panels 2, 4, and 5 on the cart side The connection structure between 10-12 and each of the panels 2, 4, 5 is not limited to the structure of the above embodiment. For example, the configuration for folding the left and right side seat portions 11 and 12 is preferably that of the above-described embodiment, but when the base sheet portion locking means 46 is used in combination, the base holding means 7 is practical even if it does not function. Since there is no problem above, the entire rear side of the left and right side seat portions 11 and 12 may be stitched and integrated with the left and right sides of the back seat portion 10. The lower side, in particular, the lower side of the side seat part 11 along the inner side of the left side panel 4 that is not folded may be integrated with the side of the base sheet part 16 as is conventionally known. Furthermore, depending on the purpose of use of the interior cover, the present invention can also be applied to an interior cover that does not have the openable / closable seat portion 15. Only the region that covers the space between the front sides of the portions 11 and 12 can be configured to be openable and closable, or the entire region from the upper side of the backsheet portion 10 to the lower side of the openable seat portion 15 as shown in the above embodiment. In the case where the door is configured to be openable and closable, another openable and closable opening can be formed in the front portion of the openable and closable sheet portion 15.
