Description

Detailed Description of the Invention

この発明は運搬器具が階段を昇降可能にするためのらせん型車輪とそのシステムに関するものである。The present invention relates to a spiral wheel and a system for allowing a carrying device to move up and down stairs.

従来運搬器具にクローラー等を取付た台車があった。There has been a cart with a crawler attached to a conventional transport device.

Problems to be solved by the invention

これらは次のような欠点があった。
（イ）階段のステップの角に車輪が接し十分な加重を受けられなかった。
（ロ）構造が複雑で重量が重く手動型の台車に取付られるようなものがなかった。These have the following drawbacks.
(B) The wheel touched the corner of the step of the stairs and was not able to receive sufficient weight.
(B) The structure was complicated and heavy, and there was nothing that could be attached to a manual cart.

Means for solving the problem

運搬器具にらせん型車輪（１）とギア付きモータ（２）及びＤＣバッテリー（３）を設置した車輪フレーム（４）を取付、台車の取っ手部に設けたコントローラー（５）にて階段の昇降を可能にした運搬器具である。Attach the wheel frame (4) with the helical wheel (1), the geared motor (2) and the DC battery (3) to the carrying device, and move up and down the stairs with the controller (5) provided on the handle of the carriage. It is a transport device that made it possible.

（イ）らせん型車輪（１）を左右に設け軸受を介してフレーム（４）に取り付ける。ギア付きＤＣモータ（２）をフレーム（４）に設置し、軸継手を介して車輪軸と連結する。フレーム（４）にＤＣバッテリー（３）設置し、台車取手部にコントローラ（５）を設ける。
（ロ）らせん型車輪（１）は車軸（１）−３にらせん型車輪フレームとガイドベアリングを配しゴムのタイヤ部分を循環するように接続した車輪である。
（ハ）階段のステップ部分にゴムのタイヤ部分が接地し車輪軸がＤＣモータにより回転することで昇降の駆動を可能とする。
（ニ）ゴムタイヤを循環させる為に、図３のようにゴムタイヤ（１）−４を１本にし循環させる方式のかわりに図５のようにゴムタイヤ（１）−４を数本にし車軸と垂直方向に循環させてもよい。(A) Helical wheels (1) are provided on the left and right sides and attached to the frame (4) via bearings. A geared DC motor (2) is installed on the frame (4) and connected to the wheel shaft through a shaft coupling. A DC battery (3) is installed on the frame (4), and a controller (5) is installed on the carriage handle.
(B) The helical wheel (1) is a wheel which is connected to the axle (1) -3 by arranging a helical wheel frame and a guide bearing so as to circulate a rubber tire portion.
(C) The rubber tire part comes into contact with the step part of the stairs, and the wheel shaft is rotated by the DC motor, so that the raising and lowering can be driven.
(D) In order to circulate the rubber tire, instead of the method of circulating one rubber tire (1) -4 as shown in FIG. 3, several rubber tires (1) -4 are used as shown in FIG. It may be circulated.

The invention's effect

台車等の階段の昇降を安全に可能にすることができる。It is possible to safely move up and down stairs such as carts.
