本考案の停止機能付きキャスター取付装置の課題は、椅子、車台などの移動器具に回転自在に取付られるキャスターにおいて、動かしたり停止させる際にペタルやレバーの操作を必要とせず、また、ペタルやレバーを使用しないのでその停止機能は劣化しない停止機能付きキャスター取付装置を提供することにある。 The problem of the caster mounting device with a stop function of the present invention is that a caster that can be rotatably mounted on a moving device such as a chair or a chassis does not require operation of a petal or a lever to move or stop the caster. The purpose of the present invention is to provide a caster mounting device with a stop function that does not deteriorate its stop function.

本考案は上記の課題を解決する為に、移動器具において、回転自在に取付られた複数のキャスターの取付金具と器具との間に勾配金具の勾配方向を相反する方向に挿入すること、また、この勾配金具をキャスター取付金具としたこと、あるいはこの勾配金具がキャスターの回転軸と一体に形成された取付ボルトが挿通する勾配座金とし、このキャスターの回転軸と一体に形成された取付ボルトを垂直線に対し傾斜させる為に、傾斜内ねじ孔を有する器具取付ボルトを介在させることなどにより、自然状態で引力により、それぞれの回転自在キャスターは相反する方向に向き合うことでペタルやレバーを必要とせずに停止機能を有し、動かす時には何ら操作なしに動かすことができる。また、この勾配金具を円形とし、その外周に沿って複数の取付孔を有することで、勾配金具の勾配の向きの更なる調整が可能とすることで複数のキャスターの垂直線に対する傾斜方向が変わり、停止機能の強弱を調整もできることを特徴とする。 In order to solve the above-mentioned problem, the present invention inserts a moving fixture in a direction opposite to the gradient direction of the gradient fitting between the fixtures of the plurality of casters mounted rotatably and the appliance. The gradient bracket is a caster mounting bracket, or the gradient bracket is a gradient washer through which a mounting bolt formed integrally with the rotation shaft of the caster is inserted, and the mounting bolt formed integrally with the rotation shaft of the caster is vertically In order to incline with respect to the wire, an instrument mounting bolt with an inclined internal threaded hole is interposed, so that each rotatable caster faces in the opposite direction without any petal or lever by natural attraction. Has a stop function and can be moved without any operation when moving. In addition, by making this gradient bracket circular and having a plurality of mounting holes along its outer periphery, it is possible to further adjust the gradient direction of the gradient bracket, thereby changing the tilt direction of the plurality of casters with respect to the vertical line. The stop function can be adjusted.

本考案のキャスター取付装置はキャスターが垂直線に対して一定の傾斜角度ａに取付られるよう勾配金具５やキャスター取付金具３３、および、勾配座金５と内側に傾斜ボルトねじ孔を有する器具取付ボルト６を介在させることなどにより、勾配方向を相反する方向に取付けることにより、自然状態でそれぞれの回転自在キャスター３は相反する方向に向くことによりペタルやレバーを必要としなくても停止機能を有し、その停止機能はペタルやレバーを必要としない構造から操作が簡単でその停止機能は持続する。 The caster mounting device according to the present invention includes the gradient fitting 5 and the caster fitting 33, and the appliance mounting bolt 6 having the inclined washer screw 5 and the inclined bolt screw hole inside so that the caster can be attached at a fixed inclination angle a with respect to the vertical line. By attaching the gradient direction to the opposite directions, such as by interposing, each rotatable caster 3 in the natural state has a stop function even if it does not require a petal or lever by facing in the opposite direction, The stop function is easy to operate because it does not require a petal or lever, and the stop function lasts.

請求項１により、図１および図２に示す如く、移動器具を台車１とした状態を示し、荷台２の底面前後にキャスター３、４を取付ている。而して、この前方のキャスター３は回転自在に取付られる。図３、図４、図５に示す如く、この回転自在に取付られるキャスター３において、取付金具３２と台車１との間にキャスター３が垂直線に対して一定の傾斜角度ａを保持すべく取付られるように勾配金具５を挿入させたことを特徴としており、この勾配金具５の勾配方向を相反する方向に挿入させることで、この進行方向左右の回転自在キャスター３は自然状態で引力により図２に示すように相反する方向に向くことにより停止機能を有する。 According to claim 1, as shown in FIGS. 1 and 2, a state in which the moving device is a cart 1 is shown, and casters 3 and 4 are attached to the front and back of the loading platform 2. Thus, the front caster 3 is rotatably mounted. As shown in FIGS. 3, 4, and 5, in this rotatable caster 3, the caster 3 is mounted between the mounting bracket 32 and the carriage 1 so as to maintain a constant inclination angle a with respect to the vertical line. As shown in FIG. 2, the gradient metal fitting 5 is inserted in the direction opposite to the gradient direction of the gradient metal fitting 5 so that the right and left rotatable casters 3 in the traveling direction are naturally attracted by an attractive force. As shown in Fig. 2, the stop function is provided by facing in opposite directions.

請求項２により、図６および図７で示す如く、この勾配金具５を円形とし、その外周に沿って複数の取付孔５１や複数の連続した取付孔５２を付したことで勾配金具５の勾配の向きの更なる調整が可能とすることで複数のキャスター３の垂直線に対する傾斜方向が変わり、停止機能の強弱を調整もできる。 According to claim 2, as shown in FIGS. 6 and 7, the gradient metal fitting 5 has a circular shape, and a plurality of attachment holes 51 and a plurality of continuous attachment holes 52 are provided along the outer periphery thereof. By enabling further adjustment of the direction, the inclination direction of the plurality of casters 3 with respect to the vertical line changes, and the strength of the stop function can be adjusted.

Further, by making the shape of the caster mounting bracket 33 circular and using a plurality of mounting holes, the strength of the stop function can be adjusted depending on the application as described in the second embodiment.

請求項４により、図１０に示す如く、台車とキャスターの間に挿入させる勾配金具５をキャスターの回転軸と一体に形成された取付ボルト３５が挿通する孔５３を有する勾配座金５とし、台車に傾斜した状態で取付けることでも同様の効果を得る。 According to claim 4, as shown in FIG. 10, the gradient fitting 5 to be inserted between the carriage and the caster is formed into a gradient washer 5 having a hole 53 through which a mounting bolt 35 formed integrally with the rotation shaft of the caster is inserted. A similar effect can be obtained by mounting the device in an inclined state.

請求項５により、図１１図１２に示す如くキャスターの回転軸と一体に形成された取付ボルト３５を器具取付ボルト６の内側に螺合させることで、台車に垂直に取付けることが可能であり、また、この器具取付ボルト６にナットを介在させることで実施例２に記するようにその用途により停止機能の強弱を調整もできる。 According to claim 5, as shown in FIG. 11 and FIG. 12, the mounting bolt 35 formed integrally with the rotating shaft of the caster is screwed into the inner side of the device mounting bolt 6 so that it can be mounted vertically on the carriage. Further, by interposing a nut on the appliance mounting bolt 6, the strength of the stop function can be adjusted depending on the application as described in the second embodiment.
