Abstract
【課題】運搬台車や介護機器等の移動器具において、キャスターの車輪径を大きくすることなく、簡単な構造で容易に段差を乗り越えることを可能とする段差対応キャスターを提供する。【解決手段】キャスターのフォーク6に、左右一対のアシスト板5を、支持軸2及び連結ボルト8で回転可能に連結する。アシスト板の支持軸を前方に押すことで段差にアシスト板底部9が接すると接地部を支点としアシスト板を起こす様に回動し、車輪10の負荷荷重が段差側に移る。同時に、アシスト板はトーションバネ4でストッパー3に戻され初期位置を保つ。これにより段差の乗り越えが容易となる。【選択図】図1To provide a step-supporting caster capable of easily climbing a step with a simple structure without increasing the wheel diameter of a caster in a mobile device such as a transport cart or a care device. A pair of left and right assist plates 5 are rotatably connected to a fork 6 of a caster by a support shaft 2 and a connecting bolt 8. When the assist plate bottom 9 comes into contact with the step by pushing the support shaft of the assist plate forward, the assist plate is pivoted to raise the assist plate with the grounding portion as a fulcrum, and the load on the wheel 10 moves to the step side. At the same time, the assist plate is returned to the stopper 3 by the torsion spring 4 to maintain the initial position. This makes it easy to get over the step. [Selection] Figure 1
Description
本考案は、運搬台車や介護機器等の移動器具に取付ける段差対応キャスターに関するものである。 The present invention relates to a caster for level difference attached to a mobile device such as a transport cart or a care device.
従来、段差を通過するにはキャスターを持ち上げる必要があり荷物等が転倒するなどの恐れがあった。そこで、下記特許文献に記載されている様に段差乗り越え用の半円アームを前輪の両側と支持金具の内側に装着し半円アームが段差と接触することで半円アームは回動し天板を持ち上げ段差を乗り越える構造となっている。 Conventionally, it has been necessary to lift a caster to pass through a step, and there has been a risk of a baggage falling. Therefore, as described in the following patent document, semi-circular arms for stepping over the step are mounted on both sides of the front wheel and the inside of the support bracket, and the semi-circular arm rotates and the top plate rotates by contacting the step. It has a structure that lifts over the steps.
しかしながら、上記の考案は半円アームを前輪の両側と支持金具の内側に装着するため主軸を避ける形状とすることが必要である。又、次の段差に備えるため半円アームをバネにより定位置に保持することが望ましい。 However, the above-described device needs to have a shape that avoids the main shaft in order to mount the semicircular arm on both sides of the front wheel and the inside of the support fitting. In order to prepare for the next step, it is desirable to hold the semicircular arm in place by a spring.
本考案は、運搬台車・介護機器等の移動器具を前方に押す力を利用し段差及び障害物等の乗り越えを容易に出来ることを課題とした。 This invention made it the subject that it was easy to get over a level | step difference, an obstruction, etc. using the force which pushes moving instruments, such as a conveyance trolley | bogie and nursing care equipment, forward.
本考案の目的は、運搬台車や介護機器等の移動器具における同一車輪径のキャスターと比べアシスト板の支持軸を前方に押すことで段差にアシスト板底部が接すると接地部を支点としアシスト板を起こす様に回動することで段差や障害物を容易に乗り越えることが出来る段差対応キャスターの提供。 The purpose of the present invention is to press the support shaft of the assist plate forward compared to a caster with the same wheel diameter in a mobile device such as a transport cart or a nursing device, and when the assist plate bottom comes into contact with the step, the ground plate is used as a fulcrum. Providing casters for level differences that can easily get over level differences and obstacles by rotating to raise.
上記の目的を達成するために本考案は、以下の形態からなる。 In order to achieve the above object, the present invention comprises the following modes.
キャスターのフォークに左右一対のアシスト板を備え支持軸及び連結ボルトで連結される。アシスト板の支持軸を前方に押すことで段差にアシスト板底部が接すると接地部を支点としアシスト板を起こす様に回動する構造であり、アシスト板底部は緩衝材や滑り防止形状にすることでより円滑に段差を乗り越えると共に段差側を保護できる。 The caster fork is provided with a pair of left and right assist plates and is connected by a support shaft and a connecting bolt. When the assist plate bottom is in contact with the step by pushing the support shaft of the assist plate forward, the support plate rotates with the grounding part as a fulcrum, and the assist plate bottom has a cushioning material or anti-slip shape. This makes it easier to get over the step and protect the step side.
支持軸を前方に押すことでアシスト板が回動し車輪の負荷荷重が段差側に移ると同時にアシスト板はトーションバネでストッパーに戻され初期位置を保つ。 By pushing the support shaft forward, the assist plate rotates and the load on the wheel shifts to the step side. At the same time, the assist plate is returned to the stopper by the torsion spring and maintains the initial position.
本考案によれば、運搬台車や介護機器等の移動器具における同一車輪径のキャスターと比べ段差や障害物を容易に乗り越えることが出来る段差対応キャスターの提供。 According to the present invention, there is provided a caster for level difference that can easily get over steps and obstacles compared to a caster having the same wheel diameter in a mobile device such as a transport cart or a care device.
以下本発明の実施の形態を図に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図1は、本考案機構の名称及び正面・側面姿図であってキャスターのフォーク(6)に左右一対のアシスト板(5)を備え支持軸(2)及び連結ボルト(8)で連結される構造であり段差にアシスト板底部(9)が接すると接地部を支点としアシスト板の支持軸(2)が前方に移動することによりアシスト板(5)を起こす様に回動し車輪(10)荷重が段差側に移ると同時にアシスト板(5)はトーションバネ(4)でストッパー(3)に戻され初期位置を保つ。 FIG. 1 is a view showing the name and front / side view of the mechanism of the present invention. The caster fork (6) is provided with a pair of left and right assist plates (5) and is connected by a support shaft (2) and a connecting bolt (8). When the assist plate bottom portion (9) is in contact with the step, the support plate (2) of the assist plate moves forward to turn the assist plate (5) to turn to cause the assist plate (5) to rotate, and the wheel (10). At the same time when the load moves to the step side, the assist plate (5) is returned to the stopper (3) by the torsion spring (4) to maintain the initial position.
図2は、段差対応キャスターが段差を乗り越える前の状態を示しておりアシスト板(5)は初期位置でありアシスト板底部(9)は段差に接触した状態である。 FIG. 2 shows a state before the step corresponding caster gets over the step, and the assist plate (5) is in the initial position and the assist plate bottom (9) is in contact with the step.
図3は、段差対応キャスターが段差を乗り越える状態を示しておりアシスト板底部(9)は段差に接触しアシスト板の支持軸(2)が前方に移動することによりアシスト板(5)を起こす様に回動し車輪(10)が浮き上がった状態である。 FIG. 3 shows a state in which the step corresponding caster gets over the step, and the assist plate bottom portion (9) comes into contact with the step and the assist plate support shaft (2) moves forward to raise the assist plate (5). And the wheel (10) is lifted up.
図4は、段差対応キャスターが段差を乗り越えた状態を示す。 FIG. 4 shows a state in which the step corresponding caster has overcome the step.
図5は、段差対応キャスターが段差上から降りた状態を示す。 FIG. 5 shows a state where the step corresponding caster descends from above the step.
本考案の段差対応キャスターは、簡単な構造で容易に段差乗り越えが可能であるため配送業務における段差乗り越え時の省力化及び衝撃吸収による静粛性を必要とする物流・工場・医療施設等における汎用性の高いキャスター。 The caster for level differences of the present invention can be easily climbed over steps with a simple structure, so it is versatile in logistics, factories, medical facilities, etc. that require labor saving and quietness by shock absorption during delivery operations. High caster.
