【実施例】 図に示す実施例は、Ｘ型脚装置１０における前側脚１の下端に椀を伏せた形状 の車輪支承部２を設け、この支承部２内に１対の半割球部材１１、１２を嵌合す ることにより得た中空球形の前側車輪３を挿入し且つ同支承部２の開口縁に車輪 押えリング４を嵌着することによって当該車輪３を抜け落ち不能および遊転自在 として支承部２内に装填すると共に支承部２の天壁と車輪３の上側面との間にベ アリング５とリテーナー６とリテーナー受７から成るベアリング装置８を軸部１ ３を介して挟装し、このベアリング装置８により上記球形車輪３にかかる荷重を 受けるようにしたものである。In the embodiment shown in the drawings, a wheel support 2 having a bowl shape is provided at the lower end of a front leg 1 of an X-shaped leg device 10, and a pair of hemisphere members 11 are provided in the support 2. , 12 are inserted into the hollow spherical front wheel 3 and the wheel retaining ring 4 is fitted to the opening edge of the bearing 2 so that the wheel 3 cannot be slipped off and can be freely rotated. The bearing device 8 including the bearing 5, the retainer 6 and the retainer receiver 7 is mounted between the top wall of the bearing 2 and the upper surface of the wheel 3 via the shaft 13 while being loaded in the bearing 2. The bearing device 8 receives the load applied to the spherical wheel 3.
【０００７】 尚、図中１５はベアリング５の転り面、１６、１７は車輪押えリング４の係止 用凹・凸部１８は車輪３の抜け落ち阻止用三角突起、１９はストッパー２０付き 後輪、２１は後側脚、２２は前・後側脚１、２１の開閉中心軸を示す。In the drawing, reference numeral 15 is a rolling surface of the bearing 5, 16 and 17 are concave and convex portions 18 for locking the wheel pressing ring 4, triangular protrusions for preventing the wheel 3 from coming off, and 19 is a rear wheel with a stopper 20. , 21 is a rear leg, and 22 is an opening / closing center axis of the front / rear legs 1, 21.
【０００８】[0008]
本考案における球状車輪３は、支承部２内において全方向に自由に回転するも のであって、上記した従来例のような首振り部を有していないものである。 The spherical wheel 3 according to the present invention can freely rotate in all directions within the support portion 2 and does not have the swinging portion as in the conventional example described above.
【０００９】[0009]
本考案に係わるベビーラックは、脚の開閉角度でベッド部（図示せず）の高低 を調節する利便な形式であり、特に上記したように脚１の下端に椀を伏せた形状 の車輪支承部２を設け、この支承部２内に球形の車輪３を挿入し且つ同部２の開 口縁に車輪押えリング４を嵌着することによって当該車輪３を抜け落ち不能およ び遊転自在として支承部２内に装填すると共に支承部２の天壁と車輪３の上側面 との間にベアリング５とリテーナー６とリテーナー受７から成るベアリング装置 ８を挟装し、このベアリング装置８により上記球形車輪３にかかる荷重を受ける ようにしたものであるので、車輪３は首振り部を有していないのに全ての方向に 自由に転向するものであって、上記した問題点を完全に解消する優れた効果を奏 するものである。 The baby rack according to the present invention is a convenient type in which the height of the bed portion (not shown) is adjusted by the opening and closing angle of the legs, and in particular, the wheel support portion in which the bowl is laid down at the lower end of the leg 1 as described above. 2 is provided, a spherical wheel 3 is inserted into the bearing portion 2, and a wheel pressing ring 4 is fitted to the opening edge of the bearing portion 2 so that the wheel 3 cannot be slid out and can be freely rotated. The bearing device 8 composed of a bearing 5, a retainer 6 and a retainer receiver 7 is inserted between the top wall of the support portion 2 and the upper side surface of the wheel 3 while being loaded in the portion 2, and the spherical wheel is provided by the bearing device 8. Since it is designed to receive the load applied to the wheel 3, the wheel 3 is free to turn in all directions even though it does not have a swinging part, which is an excellent solution to the above problems. It is effective
