Description

本発明は、車輪が縦軸回りに旋回する首振り機構を備えたキャスタ装置に関し、特に、車輪の首振り位置にかかわらず、一定の方向から車輪をロック操作できるようにしたキャスタ装置に関するものである。   The present invention relates to a caster device provided with a swing mechanism in which a wheel turns around a vertical axis, and more particularly to a caster device that can lock a wheel from a certain direction regardless of the swing position of the wheel. is there.

従来、キャビネット、テーブル、椅子等の家具を移動自在に支持するために、家具の本体や脚部の下部にキャスタ装置を取り付けている。
キャスタ装置は、横軸回りに回転する車輪と、該車輪を縦軸回りに旋回可能に支持する首振り機構とを備えている。 Conventionally, in order to support furniture such as cabinets, tables, and chairs in a movable manner, caster devices are attached to the lower part of the main body and legs of the furniture.
The caster device includes a wheel that rotates about a horizontal axis, and a swing mechanism that supports the wheel so as to be able to turn about a vertical axis.

ところで、このようなキャスタ装置には、設置後の家具の移動を防止するために、通常はストッパ機構が設けられる。
ストッパ機構は、車輪を支持する軸受け座に、車輪をばね的に押圧するストッパ部材を、その操作レバーにより係脱可能に設けたものが知られている。 By the way, such a caster device is usually provided with a stopper mechanism in order to prevent movement of furniture after installation.
A stopper mechanism is known in which a stopper member that presses a wheel in a spring manner is provided on a bearing seat that supports the wheel so that it can be engaged and disengaged by its operating lever.

しかしながら、上記従来のキャスタ装置は、ストッパ部材を車輪の軸受け座に設置することから、車輪の首振り位置によって操作レバーの方向が変わり、狭い空間で操作レバーが壁や他の家具に向いてしまうと、車輪のロック操作が非常に困難になるという問題を有している。   However, since the conventional caster device installs the stopper member on the wheel bearing seat, the direction of the operation lever changes depending on the swing position of the wheel, and the operation lever faces a wall or other furniture in a narrow space. And, there is a problem that the wheel locking operation becomes very difficult.

本発明は、上記従来のキャスタ装置が有する問題点に鑑み、車輪の首振り位置にかかわらず、一定の方向から車輪をロック操作できるようにしたキャスタ装置を提供することを目的とする。   An object of the present invention is to provide a caster device that can lock a wheel from a certain direction regardless of the swing position of the wheel in view of the problems of the conventional caster device.

上記目的を達成するため、本発明のキャスタ装置は、車輪を縦軸回りに旋回可能に支持する首振り機構を備えたキャスタ装置において、車輪の旋回軸となるボスを下部に備えて家具に固定される台座と、車輪の軸を支持するとともに、台座のボスに回動可能に嵌挿される軸受け座と、該軸受け座に設けられ、押し下げることにより車輪の一部に掛合するストッパ部材と、該ストッパ部材から台座のボスを貫通し、下方に押圧されることによりストッパ部材を押し下げる押圧突起と、台座の上面を摺動し押圧突起を押圧又は解放する操作片と、該操作片を操作する操作レバーとを備えたことを特徴とする。   In order to achieve the above object, a caster device according to the present invention is a caster device having a swing mechanism that supports a wheel so as to be pivotable about a vertical axis, and is provided with a boss serving as a pivot axis of the wheel at a lower portion and fixed to furniture. A pedestal, a bearing seat that supports the axle of the wheel and is rotatably inserted in a boss of the pedestal, a stopper member that is provided on the bearing seat and engages with a part of the wheel by being pushed down, A pressing projection that pushes down the stopper member by passing through the boss of the pedestal from the stopper member and presses downward, an operating piece that slides on the upper surface of the pedestal to press or release the pressing projection, and an operation that operates the operating piece And a lever.

本発明のキャスタ装置によれば、車輪を縦軸回りに旋回可能に支持する首振り機構を備えたキャスタ装置において、車輪の旋回軸となるボスを下部に備えて家具に固定される台座と、車輪の軸を支持するとともに、台座のボスに回動可能に嵌挿される軸受け座と、該軸受け座に設けられ、押し下げることにより車輪の一部に掛合するストッパ部材と、該ストッパ部材から台座のボスを貫通し、下方に押圧されることによりストッパ部材を押し下げる押圧突起と、台座の上面を摺動し押圧突起を押圧又は解放する操作片と、該操作片を操作する操作レバーとを備えることから、ストッパ部材を押し下げる押圧突起を車輪の旋回中心に配設するとともに、この押圧突起を一定の方向に設けた操作レバーで操作することができ、これにより、車輪の首振り位置にかかわらず、一定の方向から容易に車輪をロック操作することができる。
また、このキャスタ装置は、車輪の軸を除く主要部品を合成樹脂製の成型品で構成することによって、部品点数を削減するとともに、機構を簡略化することができ、これにより、装置の組立作業が容易になるとともに、製造コストを著しく低廉にできる。 According to the caster device of the present invention, in the caster device provided with a swing mechanism that supports the wheel so as to be pivotable about the vertical axis, a pedestal that is provided with a boss serving as a pivot shaft of the wheel and is fixed to the furniture, A bearing seat that supports the axle of the wheel and is rotatably fitted to the boss of the pedestal, a stopper member that is provided on the bearing seat and engages with a part of the wheel by being pushed down, and from the stopper member to the pedestal A pressing projection that penetrates the boss and presses down the stopper member when pressed downward, an operating piece that slides on the upper surface of the base and presses or releases the pressing projection, and an operating lever that operates the operating piece are provided. From the above, a pressing projection that pushes down the stopper member can be disposed at the center of rotation of the wheel, and this pressing projection can be operated with an operation lever provided in a fixed direction. Regardless of swing position, it is possible to easily lock operation wheels from a fixed direction.
In addition, this caster device can reduce the number of parts and simplify the mechanism by constructing the main parts excluding the wheel shafts from synthetic resin moldings. And the manufacturing cost can be significantly reduced.
