類、オフィスオートメーション機器、電気洗濯機等の電
気製品など各種の可搬物のキャスタ等として使用される
自在車に関する。Detailed Description of the Invention "Field of Industrial Application" The present invention is applicable to various portable objects such as bags such as travel bags, furniture such as chairs and desks, office automation equipment, and electrical appliances such as electric washing machines. This invention relates to swivel wheels used as casters, etc.
「従来の技術」
従来のキャスタは、一般に、車輪を水平回転自在な車枠
に水平な車軸によって軸支し、車枠が水平回転すること
によって方向転換する構造であった。"Prior Art" Conventional casters generally have a structure in which a wheel is supported by a horizontal axle on a horizontally rotatable car frame, and the direction is changed by the horizontal rotation of the car frame.
「発明が解決しようとする問題点」
このため、キャスタ自体その走行方向の変更がスムーズ
でなく、それに支持されている可搬物の向きを強制的に
変えて方向転換しなければならないこともあり、また車
輪を軸支する軸受の他に車枠を軸支するための軸受が必
要であるため、製造コストが高くなるとともに、キャス
タ自体の高さが高くなる等の問題があった。``Problem to be solved by the invention'' For this reason, the casters themselves do not change their running direction smoothly, and it may be necessary to forcibly change the direction of the portable object supported by them. Moreover, since a bearing for supporting the vehicle frame is required in addition to a bearing for supporting the wheel, there are problems such as increased manufacturing cost and the height of the caster itself.
本発明の目的は、車枠を軸支する必要がなくしかも支持
する可搬物の向きを強制的に変えるようなことなく走行
方向の変更がスムーズに行え、かつ小型化できるととも
に、製造コストも低廉な自在車を提供することにある。The purpose of the present invention is to make it possible to smoothly change the running direction without having to pivot the vehicle frame, and without forcibly changing the direction of the supported transportable object, to reduce the size of the vehicle, and to reduce manufacturing costs. Our aim is to provide flexible cars.
「問題点を解決するための手段」
このような目的を達成するため、本発明の自在車は、円
形でしかも外周面が球面をなす車輪の中央部を車軸に球
面軸受けし、また該車輪の両側面に、その球面軸受部に
向かって円錐形にすぼまる凹部を形成したものである。"Means for Solving the Problems" In order to achieve such an object, the swivel vehicle of the present invention has a circular wheel with a spherical outer circumferential surface, and has a spherical bearing on the axle at the center of the wheel. A concave portion is formed on both sides of the bearing, which tapers into a conical shape toward the spherical bearing portion.
「作 用」
かかる構造によると、車輪が車軸に対して回転自在であ
るとともに中心部で揺動自在になるため、車枠を水平回
転自在に軸支することなく、走行方向を変えることがで
きる。"Function" According to this structure, the wheels are rotatable relative to the axle and swingable at the center, so the running direction can be changed without horizontally rotatably supporting the vehicle frame.
「実施例」 以下に本発明の実施例について説明する。"Example" Examples of the present invention will be described below.

コア２の中心部には球面孔５が設けられている。そして
、この球面孔５を車軸６に固着された球体７と嵌合させ
ることにより、車輪ｌは車軸６に対して球面軸受けされ
、回転自在でしかも全方向に揺動自在になっている。In the embodiment shown in FIGS. 1 to 4, the wheel l has a covering material 3 made of an elastic material such as rubber attached to the outer periphery of a circular core 2 made of metal or hard synthetic resin.
a is a parallel vertical surface, and the surface 3a of the covering material 3 is a spherical surface with a radius r from the center of the circular core 2. On both side surfaces 2a of the circular core 2, conical recesses 4 that narrow toward the center of the circular core 2 are provided point-symmetrically, and a spherical hole 5 is provided at the center of the circular core 2. It is being By fitting this spherical hole 5 with a sphere 7 fixed to the axle 6, the wheel 1 is spherically supported on the axle 6 and is rotatable and swingable in all directions.
従って、車軸５が水平のまま直線走行しているときは、
車輪ｌは垂直のまま転勤し、緩やかな左折時または右折

部４の範囲内に制限されるため、車輪ｌが妄りに旋回し
て走行する方向性が定まらなくなるようなことはない。Therefore, when traveling in a straight line with the axle 5 horizontal,
The wheels 1 move vertically, and when making a gentle left or right turn, the wheels 1 swing left or right while remaining perpendicular to the axle 5, forcing the direction of the supported transportable object. You can smoothly change direction without having to change direction. Also, when making a sharp curve or U-turn, the fourth wheel is
As shown in the figure, it swings to the left or right, so this is also done smoothly. However, since the swinging is limited within the range of the recesses 4 on both sides, the wheels 1 will not turn inadvertently and the direction of travel will not be determined.

In the example shown in the figure, in order to provide directivity in the running direction, the thickness of the facing material 3 is increased, and both sides 3b of the covering material 3 are used as both sides 2 of the circular core 1.
This is a vertical plane that is flush with a. In the example shown in FIG. 6, the sphere 7 is enlarged so that it can support a heavy portable object. In the example shown in FIG. 7, a pair of auxiliary spheres 8 are fixed to the axle 6 in order to smoothly slide between the recess 4 and the axle 5.
