Abstract

<P>PROBLEM TO BE SOLVED: To provide a carry cart for facilitating ascent/descent of steps and stairs while conveying the carry cart by slipping a carry cart body on projecting parts of the steps and pulling it similar to the normal walking without imposing any forced posture by solving a problem that the carry cart must be lifted up when ascending/descending the steps. <P>SOLUTION: A slipping tool 6 to be brought into contact with projecting parts of steps is provided on a back side part 7 of a carry cart. The ground contact area of the slipping tool 6 is reduced as much as possible for reducing the friction with the projecting parts of the steps, and both ends 5 thereof are formed in a smooth curve to mitigate the shocks when it is brought into contact with the ground. A movable unit 9 and an expansion unit 11 are provided on a supporting part 10. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、段差や階段の昇降時に本体を腕力によって持ち上げることなく、段差を滑らせ、衝撃なく、平地歩行時と同様の無理のない姿勢で運搬できるキャリーカートに関するものである。  The present invention relates to a carry cart that can be transported in a comfortable posture similar to that when walking on a flat surface, without sliding, by sliding the step without lifting the main body by arm force when raising or lowering the step or the stairs.
従来、荷物運搬を容易にするため底部に車輪を有したキャリーカートが使用されている。
この際、段差や階段の昇降時には車輪を使用しての運搬ができないため、台軸と車輪の接地面の間に滑り具を設ける手法(特許文献1参照)や、キャリーカート背面部に対し角度を付けた斜支枠を設ける手法(特許文献2、特許文献3参照)、キャリーカート背面部に対し角度を付けた伝動用ベルトを設ける手法(特許文献4)などが公知となっている。

従来の荷物運搬用キャリーカートは、底面に配置された車輪による平地輸送用に設計されたものであり、段差又は階段昇降時には通常の牽引姿勢では衝撃が大きくなるため、腕力によって持ち上げ、地面より離して運搬しなければならなかった。そのため、キャリーカート背面部に対し角度を付けた斜支枠を設ける手法やカート背面部にベルトやキャタピラ様の伝動用器具を設ける手法がすでに考案されているが、実際に使用する際は踵にぶつかりやすい、器具そのものの重量がかさむ、構造が複雑で製造コストがかさむなどの問題があった。
本発明は、以上の問題点を解決し、キャリーカートを持ち上げることなく、無理のない歩行姿勢のまま、衝撃なく、段差または階段昇降時にキャリーカートを運搬できるようになされたものである。
Conventional carry carts for cargo transportation are designed for transportation on flat ground with wheels arranged on the bottom surface, and when raising or lowering a step or a staircase, the normal pulling posture increases the impact, so it is lifted by arm force and separated from the ground. Had to be transported. For this reason, methods have been devised to provide a diagonal support frame that is angled with respect to the back of the carry cart and a method of providing a belt or a caterpillar-like transmission device on the back of the cart. There were problems such as being easily hit, the weight of the device itself being increased, the structure being complicated and the manufacturing cost being increased.
The present invention solves the above-described problems, and can carry the carry cart while raising or lowering a step or a staircase without raising the carry cart, in a comfortable walking posture, and without impact.
キャリーカート本体と牽引するためのハンドルの間の支持部に固定することも可能で、キャリーカート本体に対する支持部の角度を自由に変化できる可動部を設ける。ハンドルの長さを平地使用時よりも長くできるよう伸縮部を設ける。キャリーカート本体背面部に段差との接地面積を極力小さくした一つ以上の滑り具を設ける。滑り具の両端は接地をスムーズにするための滑らかな曲線で形成する。
本発明は、以上の構成よりなる段差昇降を円滑にするキャリーカートである。
It is also possible to fix to the support part between the carry cart body and the handle for towing, and to provide a movable part that can freely change the angle of the support part with respect to the carry cart body. A telescopic part is provided so that the length of the handle can be longer than when using flat ground. One or more sliding tools having a ground contact area with the step as small as possible are provided on the back surface of the carry cart body. Both ends of the sliding tool are formed with a smooth curve for smooth grounding.
The present invention is a carry cart that smoothly moves up and down a step having the above-described configuration.
本発明を使用することにより、キャリーカート本体背面部の滑り具が階段の凸部に接して滑り上げ、または滑り下げができるため、段差を超える際の衝撃がなく、円滑に段差や階段の昇降が可能となる。また、可変部と伸縮部を設けていることにより、平地使用時と同様の無理のない歩行姿勢で段差や階段の昇降が可能となる。  By using the present invention, the sliding tool on the back of the carry cart body can slide up or down while touching the convex part of the staircase, so there is no impact when going over the step, and the step and the staircase can be raised and lowered smoothly. Is possible. Moreover, by providing the variable part and the expansion / contraction part, it is possible to move up and down steps and stairs in a comfortable walking posture similar to when using flat ground.
以下、本発明の実施の形態を説明する。
(イ)キャリーカート本体(1)と接地面(2)との間のキャリーカート背面部(7) に、接地面(2)との摩擦を極力小さくするための曲線(3)又は0〜180度 の角度(4)を付け、両端を滑らかな曲線(5)にした滑り具(6)を一つ以上 設ける。
(ロ)キャリーカート本体(1)と牽引用ハンドル(8)の間の支持部(10)にキャ リーカート本体(1)に対して支持部(10)の角度を自由に変化でき、固定も 可能な可動部(9)を設ける。
(ハ)可動部(9)と牽引用ハンドル(8)の間の支持部(10)の長さを平地使用時 よりも長くできるよう伸縮部(11)を設ける。
本発明は以上の構成よりなる。
本発明を段差や階段の昇降時に使用する場合は、平地使用時には固定されている可変部(9)を解除し、キャリーカート本体(1)と支持部(10)の角度を自由に変えられるようにし、伸縮部(11)を平地使用時よりも長くして使用する。
Embodiments of the present invention will be described below.
