Description
本発明は,雪の路面でも、雪のない路面でも簡単に切り替えて荷物の運搬が出来る台車に関する。 The present invention relates to a trolley that can easily switch a load on a snowy road surface or a snowless road surface.
従来,台車で荷物を運搬するに当たり、雪の降る地方では、冬は台車が通る路面が雪であっても、場所によっては雪がない路面もあり、誰もが苦労をして来た問題である。

Conventionally, when transporting luggage with a trolley, in snowy regions, even in the winter, even when the trolley is snowy, there are some places where there is no snow in some places. .

Japanese Patent Application No. 07-352136 (foldable trolley for rooted trees) The contents of the above are described in the gazette, but the technical and structural differences are large.
荷物の運搬は、台車を使用する事により、便利であり仕事の能率も上がる。
会社の経営において、欠かせないものである。
しかし、雪の降る地方では大手の運送会社の運転手が、雪の積もった歩道で荷物を積んだ台車を押して歩き、雪の中で動けなくなり荷物も雪の中に落ちて大変な思いをしている場面を何回も見て、大変さを実感している。
何とか、雪の積もっている路面では橇を使用し、ロードヒーティングを使用している路面では雪がない為、瞬時に車輪に切り替える事が出来る台車を開発することが出来ないか。これを解決する事は大きな課題である。
The use of a trolley for carrying luggage is convenient and increases work efficiency.
It is indispensable in the management of the company.
However, in a snowy region, the driver of a major transportation company walked by pushing a trolley loaded with luggage on a snowy sidewalk and became stuck in the snow, and the luggage fell in the snow and felt serious. I saw the scene many times and realized the difficulty.
Is it possible to develop a bogie that can switch to wheels instantly because sleds are used on snowy roads and there is no snow on roads that use road heating? Solving this is a major challenge.
課題を解決するために本発明は,以下の構成とした。
台車の床面(1)は金属製の素材を使用し、取っ手(3)の部分も金属製の丸パイプを使用して、必要により折り畳める構造にした。
左右前輪(8)と左右後輪(9)は、金属製と合成樹脂を使用して車輪の地面に接する分部はゴム製であり、中心部は金属製を使用した。
In order to solve the problem, the present invention has the following configuration.
The floor (1) of the cart was made of a metal material, and the handle (3) was made of a metal round pipe so that it could be folded as necessary.
The left and right front wheels (8) and the left and right rear wheels (9) are made of metal and synthetic resin, and the portion of the wheel that contacts the ground is made of rubber, and the center is made of metal.
台車床面(1)に、荷物を積んで移動しようとすると、雪の多く降る地方では4箇所に設置した車輪に、「雪がつまる」「凍結する」以上の理由で回転しなくなる可能性が高い。
そのため、図3、図4に記載したように台車に橇(10)を設置して、必要に応じて何時でも簡単に切り替え出来るようにした。
歩道を台車で荷物を運搬しようとしても、歩道の信号が青の時に、急いで渡ろうとしても、台車が大きく傾き荷物は歩道に散乱する危険性がある。
また、上手く移動出来たとしても、そのビルに依って歩道にロードヒーティングを使用している場合は、雪がなく左右前輪(8)も、左右後輪(9)も橇から車輪に切り替えしなければ荷物の運搬は出来ない。
If you try to move with the luggage on the cart floor (1), there is a high possibility that the wheels installed at four locations in the area where snow falls a lot will not be able to rotate for more than "snow clogs" or "freezes" .
Therefore, as shown in FIGS. 3 and 4, a sled (10) is installed on the truck so that the truck can be easily switched at any time as needed.
Even if you try to carry your luggage on the sidewalk with a trolley or if you try to cross quickly when the sidewalk light is green, there is a risk that the trolley will tilt greatly and the luggage will be scattered on the sidewalk.
Also, even if it is able to move well, if road heating is used on the sidewalk depending on the building, the left and right front wheels (8) and the left and right rear wheels (9) must be switched from sleds to wheels without snow. If you cannot carry your luggage.
そのため、雪のある場所では、車輪から橇(10)に切り替え、雪のない場所では橇(10)から車輪に切り替えて、簡単操作で荷物を予定通りに行うことが出来る構造にした。 Therefore, in places with snow, the wheels are switched to the sleds (10), and in places without snow, the sleds (10) are switched to the wheels, so that the baggage can be carried out as scheduled by simple operation.
夏秋は一般の台車と同様に車輪を使用して荷物の運搬を行い、雪の降る季節になると路面が雪の場合は、瞬時に車輪から橇に切り替え、ロードヒーティングを使用して路面の雪を溶かしている場所では瞬時に橇から車輪に切り替える事が出来る為、極めて便利である。 In summer and autumn, use a wheel to carry luggage in the same way as a general trolley. It is very convenient because you can instantly switch from a sled to a wheel in a place where you are melting.
台車床面(1)に、荷物を積んで移動しようとすると、雪の多く降る地方では4箇所に設置した車輪に、雪がつまり、また気温が−10℃、−15℃の様に気温が低いと雪がつまった車輪は凍結して、回転しなくなる可能性が高い。
そのため、図3、図4に記載したように台車に橇(10)を設置して、必要に応じて何時でも簡単に切り替え出来るようにした。
歩道を台車で荷物を運搬しようとしても、歩道の信号が青の時に、急いで渡ろうとしても、台車が大きく傾き荷物は歩道に散乱する危険性がある。また、上手く移動出来たとしても、そのビルによって歩道にロードヒーティングを使用している場合は、雪がなく左右前輪(8)も、左右後輪(9)も車輪に切り替えしなければ荷物の運搬は出来ない。
If you try to move with the luggage on the cart floor (1), snow is clogged on the wheels installed at four places in the region where much snow falls, and the temperature is as low as -10 ° C and -15 ° C And the snow-clogged wheels are likely to freeze and stop spinning.
Therefore, as shown in FIGS. 3 and 4, a sled (10) is installed on the truck so that the truck can be easily switched at any time as needed.
Even if you try to carry your luggage on the sidewalk with a trolley or if you try to cross quickly when the sidewalk light is green, there is a risk that the trolley will tilt greatly and the luggage will be scattered on the sidewalk. Even if you can move well, if the building uses road heating on the sidewalk, there is no snow and the left and right front wheels (8) and left and right rear wheels (9) must be switched to wheels to carry luggage. Can not.
そのため、雪のある場所では、車輪から橇(10)に切り替え、雪のない場所では橇(10)から車輪に切り替えて、簡単操作で荷物を予定通りに運搬出来る構造にした。 For this reason, in places with snow, the wheels are switched to the sleds (10), and in places without snow, the sleds (10) are switched to the wheels, so that the cargo can be transported as scheduled by simple operation.
使用方法として、取っ手を折り畳める構造は、一般的な構造であるが、「車輪から橇に」「橇から車輪に」瞬時に変更できる事が極めて重要である。
「車輪から橇」に切り替える場合は、橇(10)を前後に移動させる持ち手(11)を前方に移動させて、車輪から橇に切り替えた状態のフック(5)で固定する。
「橇から車輪」に切り替える場合は、橇を前後に移動させる持ち手(11)を後方に移動させて、橇から車輪に切り替えた状態のフック(4)で固定する。
As a method of use, the structure in which the handle can be folded is a general structure, but it is extremely important that the handle can be instantaneously changed from “wheel to sled” or “from sled to wheel”.
When switching from "wheel to sled", the handle (11) for moving the sled (10) back and forth is moved forward and fixed with the hook (5) switched from the wheel to the sled.
When switching from the sled to the wheel, the handle (11) for moving the sled back and forth is moved backward and fixed with the hook (4) switched from the sled to the wheel.
台車の床面は金属製の素材を合成樹脂に変えて使用し、取っ手の部分も金属製の丸パイプを使用して、4箇所の車輪は、金属製と合成樹脂を使用して車輪の地面に接する分部はゴム製であるが、前記ゴム製は合成樹脂を使用出来るようにした。 The floor of the trolley is made of synthetic resin instead of metal, and the handle is made of round metal pipes. The four wheels are made of metal and synthetic resin. The portion in contact with is made of rubber, but the rubber is made of synthetic resin.
橇から車輪に切り替えた状態のフック(4)と車輪から橇に切り替えた状態のフック(5)の2つを必要とするが、フック2つは設置場所が狭いため、橇から車輪に切り替えた状態のフック(4)のみとして中間と先端2箇所をフック状にする事が出来る。 Two hooks are required: a hook (4) that switches from a sled to a wheel and a hook (5) that switches from a wheel to a sled. With only the hook (4) in the state, the middle and the two ends can be formed in a hook shape.
