Description

本考案は商品や製品を載置して搬送する搬送車のキャスター用タイヤに関するものである。The present invention relates to a tire for a caster of a transporting vehicle that loads and transports products and products.

従来の搬送車のキャスター用タイヤには、天然ゴム・ブタジェンゴム・スチレンブタジェンゴム・ナイロン・ウレタンなどの材質を用いたものが主流であり、その他としてクッション性を高めるために空気入り或はゴム発砲・ウレタン発砲のものがある。Conventional transporter caster tires are mainly made of materials such as natural rubber, butadiene rubber, styrene butadiene rubber, nylon, and urethane.In addition, pneumatic or rubber foaming is used to improve cushioning.・ There are urethane firing types.

 解決しようとする問題点として、このように搬送車のキャスター用タイヤに使用している天然ゴム・ブタジェンゴム・スチレンブタジェンゴム製は、長期に使用していると、ひび・割れが起こりやすく、タイヤの硬さも限られているためクッション性がなく、路面・接地面が悪いと段差を通過することが非常に困難である。As a problem to be solved, the natural rubber, butadiene rubber, and styrene butadiene rubber used for the caster tires of transport vehicles are susceptible to cracking and cracking when used for a long period of time. Because of its limited hardness, it has no cushioning properties, and it is very difficult to pass over a step if the road surface or the ground contact surface is poor.

 又、ナイロン・ウレタン製は、硬く長期にわたり使用出来る長所があるが、天然ゴム・ブタジェンゴム・スチレンブタジェンゴム製以上に路面に応じてタイヤが変形することがないので同様に段差などを乗り越えるのが困難である。
更に、空気入り製は、空気が抜けたりパンクする可能性が高くその都度の管理が大変であると共に、ゴム発砲・ウレタン発砲製は、発泡のために長期使用や長期保管時に発泡層が崩れ、縮みが生じて外れてしまったりする。
In addition, nylon and urethane products have the advantage of being hard and can be used for a long period of time. Have difficulty.
In addition, pneumatic products have a high possibility of air bleeding or puncture and are difficult to manage each time, while rubber and urethane foam products have foam layers that collapse during long-term use or long-term storage due to foaming, They shrink and come off.

 特に路面・接地面が悪い場所或は僅かに段差のある場所での搬送時には、搬送による独特の異音を発するため、夜間においてはそれが騒音となり安眠を妨害するなど環境問題を起こす要因になってきている等搬送車用の車輪として使用上非常に不都合を感じていた。In particular, when transporting on a place with a bad road surface or ground contact surface or a place with a slight level difference, a unique noise is generated by the transport, and at night it becomes a noise and may cause environmental problems such as disturbing sleep. I felt very inconvenience in using it as a carrier wheel.

 天然ゴムよりなるリング状でその両側面に凹状の環溝を環状に穿設し、環溝に直交して環溝の内側の両側面一箇所或は数箇所に切溝を環溝に一端が接続するよう穿設してなる内タイヤを、合成ゴムよりなる薄厚さの外タイヤ内に嵌入にて組合せ一体化したものである。A ring-shaped groove made of natural rubber is provided with annular concave grooves formed on both sides in a ring shape, and a cut groove is formed at one or several sides on both sides inside the ring groove perpendicular to the ring groove, and one end is formed on the ring groove. An inner tire formed to be connected is fitted and integrated into a thin outer tire made of synthetic rubber.

 このように組合わせて一体化させたタイヤは、内タイヤの天然ゴムによる、反発弾性・耐磨耗性・耐寒性・振動防止・騒音防止の特性を生かし、内タイヤの天然ゴムの弱点である耐油性・耐候性を外タイヤで補っている。
 そして環溝によって、タイヤとしての弾性を十分に引き出し且つ軽量化を計ると共に、タイヤのホイール装着時に生じる圧迫による内タイヤ(天然ゴム)の膨らみを防止する。
 更に、切溝によってタイヤのホイール装着時に発生するタイヤ内の空気圧を外に押し出し、ホイールの装着が容易に行なえ車輪としてその機能を十分に発揮することが出来るためその利用範囲も広くなる等実用上非常に優れた考案である。
The tire integrated in this way is a weak point of the natural rubber of the inner tire, making use of the characteristics of rebound resilience, abrasion resistance, cold resistance, vibration prevention and noise prevention by the natural rubber of the inner tire. Oil resistance and weather resistance are supplemented by outer tires.
The annular groove sufficiently enhances the elasticity of the tire and reduces the weight, and prevents the inner tire (natural rubber) from bulging due to compression generated when the tire is mounted on the wheel.
Furthermore, the kerf pushes out the air pressure in the tire generated when the tire is mounted on the wheel, and the wheel can be easily mounted and the function of the wheel can be sufficiently exhibited, so that the range of use can be widened. This is a very good idea.

 天然ゴムよりなるリング状でその両側面に凹状の環溝を環状に穿設し、環溝に直交して環溝の内側の両側面一箇所或は数箇所に切溝を環溝に一端が接続するよう穿設してなる内タイヤを、合成ゴムよりなる薄厚さの外タイヤ内に嵌入にて組合せ一体化したものである。A ring-shaped groove made of natural rubber is provided with annular concave grooves formed on both sides in a ring shape, and a cut groove is formed at one or several sides on both sides inside the ring groove perpendicular to the ring groove, and one end is formed on the ring groove. An inner tire formed to be connected is fitted and integrated into a thin outer tire made of synthetic rubber.

 以下本考案の一実施例を図面について説明する。
 図中1はキャスター用タイヤ全体を示し、2は合成ゴムよりなる薄厚さの外タイヤであって、外周にトレッド部3を設け、トレッド部3両側にリムライン4を環状に凸設するサイド部5を設けて断面を略U字形とし、サイド部5先端にビート6を内側に向けて設けている。
An embodiment of the present invention will be described below with reference to the drawings.
In the drawing, reference numeral 1 denotes an entire caster tire, 2 denotes a thin outer tire made of synthetic rubber, and a tread portion 3 is provided on the outer periphery, and a side portion 5 in which rim lines 4 are annularly protruded on both sides of the tread portion 3. Is provided, and the cross section is substantially U-shaped.

 7は天然ゴムよりなり断面が略円形でリング状の内タイヤであって、外周を湾曲面としたクラウン部8とし、両側に内方向に傾斜させたサイド部9を設け、サイド部9端部に内周を内方向に凸状とした内周部10を設け、クラウン部8とサイド部9の接続部にU字形とした凹状の環溝11を環状に穿設すると共に、サイド部9の一箇所に環溝11直交にて接続する切溝12を穿設している。Reference numeral 7 denotes a ring-shaped inner tire made of natural rubber and having a substantially circular cross section, a crown portion 8 having a curved outer periphery, side portions 9 inclined inward on both sides, and an end portion of the side portion 9. An inner peripheral portion 10 having an inner periphery protruding inwardly is provided at the connecting portion between the crown portion 8 and the side portion 9, and a U-shaped concave annular groove 11 is formed in an annular shape. A cut groove 12 is formed at one location and connected to the annular groove 11 orthogonally.

 使用に当たっては、トレッド部3内側にクラウン部8を、サイド部5内側にサイド部9をそれぞれ対応させてビート6にて内周部10を抱え込むようにし、外タイヤ2内に内タイヤ7を嵌入にて組合わせ一体化させてタイヤ1として用いる。
 このように組合わせたタイヤ1は、内タイヤ7の天然ゴムによる、反発弾性・耐磨耗性・耐寒性・振動防止・騒音防止の特性を生かし、内タイヤ7の天然ゴムの弱点である耐油性・耐候性を外タイヤ2で補っている。
In use, the inner peripheral portion 10 is held by the beat 6 in correspondence with the crown portion 8 inside the tread portion 3 and the side portion 9 inside the side portion 5, and the inner tire 7 is inserted into the outer tire 2. And used as a tire 1.
The tire 1 combined in this manner makes use of the natural rubber of the inner tire 7 to have the properties of rebound resilience, abrasion resistance, cold resistance, vibration prevention, and noise prevention. The outer tire 2 supplements the properties and weather resistance.

 そして環溝11によって、タイヤ1としての弾性を十分に引き出し且つ軽量化を計ると共に、タイヤ1のホイール装着時に生じる圧迫による内タイヤ7(天然ゴム)の膨らみを防止する。
 更に、切溝12によってタイヤ1のホイール装着時に発生するタイヤ1内の空気圧を外に押し出し、ホイールの装着が容易に行なえ車輪としてその機能を十分に発揮することが出来る。
The annular groove 11 allows the elasticity of the tire 1 to be sufficiently drawn out and reduced in weight, and prevents the inner tire 7 (natural rubber) from bulging due to compression generated when the tire 1 is mounted on the wheel.
Further, the air pressure generated in the tire 1 when the wheel is mounted on the tire 1 is pushed out by the kerf 12, so that the wheel can be easily mounted and the function as the wheel can be sufficiently exhibited.
