【考案の詳細な説明】 《産業上の利用分野》 本考案は、運搬用台車等に取付けて使用されるの自在車
輪に関する。一般に運搬用台車では、安定した走行を行
うために、首振り可能な自在車輪と、首振りしない転輪
とを合せて使用している。ところが、台車を狭い場所に
格納したり、狭い場所で方向変更したりする場合には、
首振りしない転輪を使用していると、台車の姿勢変更の
ために大きなスペースを要するうえ、切返しを何回も行
なわなければならないという問題がある。DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a universal wheel that is used by being attached to a carriage or the like. Generally, in a trolley for transportation, in order to perform stable traveling, a free wheel that can swing and a rolling wheel that does not swing are used together. However, if you want to store the trolley in a narrow place or change the direction in a narrow place,
The use of a wheel that does not swing causes a problem that a large space is required for changing the posture of the trolley, and the car needs to be turned over many times.
一方、全車輪を自在車輪で構成すると姿勢変更時には操
作が楽になるが、通常の走行時にその走行が安定しない
という問題がある。On the other hand, if all the wheels are composed of free wheels, the operation becomes easy when changing the posture, but there is a problem that the traveling is not stable during normal traveling.
本考案は、このような点に鑑み提案されたもので、首振
り旋回自在な状態の自在車輪と、台車に対して固定され
る状態の転輪とに切換えて使用可能な自在車輪を提供す
るものである。The present invention has been proposed in view of the above circumstances, and provides a universal wheel that can be used by switching between a universal wheel that can be swung freely and a rolling wheel that is fixed to a carriage. It is a thing.
《従来技術》 従来、自在車輪の首振り旋回をロックできるようにした
首振り停止機構付きの自在車輪として、例えば、実開昭
58-179203号に示されたものがある。<< Prior Art >> Conventionally, as a universal wheel with a swing stop mechanism that can lock the swing of the universal wheel, for example,
There is one shown in No. 58-179203.

枢支枠を旋回不能な状態にロックするようにしている。This is because a bifurcating pivot frame that pivotally supports a wheel is supported by a mounting bracket so that the bifurcating pivot frame can swing and swivel, and a braking / turning stop operation tool is mounted on a connecting wall portion of the bifurcating pivot frame. The brake is supported and the brake piece is pressed against the peripheral surface of the wheel by the operation of the braking / turning stop operation tool to brake the wheel, and the turning stop tool is provided on the axis of the turning pivot shaft of the bifurcated pivot frame. The two-pronged pivot frame is locked so as not to turn by contacting the end.
《解決しようとする問題点》 ところが、前記従来のものでは、旋回ロックと同時に車
輪も制動状態になるから、旋回を停止した状態で走行さ
せることはできなかった。<< Problems to be Solved >> However, in the above-mentioned conventional one, since the wheels are in the braking state at the same time as the turning lock, it is impossible to drive the vehicle while turning is stopped.
これは、従来のものが、台車あるいは自在車輪を取付け

う技術課題から来るもので、首振り旋回可能な自在車輪
としての使用状態と、首振りしない転輪としての使用状
態にとに切換えるという思想がなかったことに由来す
る。This is due to the technical problem that the conventional ones can fix the dolly or the article to which the free wheel is attached in a stable posture. It originates from the fact that there was no idea to switch to the state of use as a rolling wheel.
また、制動兼旋回停止用操作具が二又枢支枠の連結壁部
に設けてあることから、制動兼旋回停止用操作具が台車
等の下側に入り込むと、操作用の空間が狭くなって操作
しにくいという問題があった。Further, since the braking / turning stop operation tool is provided on the connecting wall portion of the bifurcated pivot frame, when the braking / turning stop operation tool enters the lower side of the trolley or the like, the operation space becomes narrow. There was a problem that it was difficult to operate.

The stepping operation piece is arranged outside one of the legs of the pivot frame in a state of being swingably supported by the wheel pivot shaft, and the stepping operation piece of the connecting wall portion of the bifurcated pivot frame facing the circumferential surface of the wheel is arranged. A spring lock rod, which is configured to be elastically deformable by bending a spring steel rod on the upper surface, is supported so as to be capable of undulating and swinging, and is positioned so as to sandwich a swing center axis in a mounting bracket.
An engaging portion that engages with the swivel lock tool is formed in at least one of the locations, one end of the swivel lock tool is linked to a stepping operation, and the swivel lock tool is engaged by a switching operation of the stepping operation piece. It is characterized in that it is configured to engage and disengage.

自由に転動することになる。<Operation> According to the present invention, the swing lock member is supported on the upper surface of the connecting wall portion of the bifurcated pivot frame so as to be capable of swinging up and down, and the swivel lock is mounted on the mounting bracket pivotally supporting the bifurcated pivot frame. The turning lock is linked to the stepping operation tool supported on the wheel pivot shaft on the outside of the leg of the bifurcated pivot support, so that the operation of the stepping operation tool is performed. Therefore, the free wheel is locked with only the swinging turning of the wheel being stopped, and the wheel is free to roll.

When the swivel lock is elastically deformed to absorb the operating force, and the swivel movement thereafter swivels to a position in a predetermined direction and the phases of the swivel lock and the engaging portion match, the swivel lock is engaged. You will be involved in the joint department.
