動作がスムーズでなくなったり、静止時のスタンドの安
定性が損われてしまう。In the conventional tilt and swivel mechanism, as described in Japanese Utility Model Laid-Open No. 59-54977, a pair of convex and concave spherical sliding surfaces are in contact with each other over a wide area. For this reason, the contact of the sliding surface is likely to be uneven due to the accuracy of the spherical shape and the variation of the warp, and if it becomes uneven, the weight of the attached device is unbalanced and the tilt / swivel The movement may not be smooth or the stability of the stand when stationary may be impaired.
上記従来技術は、摺動面の接触を均一にするための配慮

スイーベル動作がスムーズでなくなったり、静止時のス
タンドの安定性が損われるという問題があった。The above-mentioned prior art does not consider to make the contact of the sliding surface uniform, and if the contact becomes uneven, tilt
There were problems that the swivel movement became unstable and the stability of the stand when stationary was impaired.
本考案の目的は、動作がスムーズで静止時の安定性が良
好なチルト・スイーベル機構を提供することにある。An object of the present invention is to provide a tilt and swivel mechanism that operates smoothly and has good stability when stationary.
上記目的は、１組の凸球面と凹球面からなる摺動面の凹
球面に複数の凸部を設けて、凸球面と部分的に接触させ
る構造とすることにより達成される。The above object can be achieved by providing a plurality of convex portions on a concave spherical surface of a sliding surface composed of a pair of convex spherical surface and concave spherical surface so as to partially contact the convex spherical surface.
複数の凸部は部分的に相手球面と接するため、球面形状
の精度や反りのばらつき等により凸球面と凹球面の曲率
が同一になっていなくても摺動面の接触が不均一になる
ことはない。Since the multiple convex parts are partially in contact with the mating spherical surface, the contact of the sliding surface will be uneven even if the convex spherical surface and concave spherical surface do not have the same curvature due to variations in spherical shape accuracy and warpage. There is no.
以下、本考案の一実施例を第１図および第２図により説
明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
チルト・スイーベル機構は固定台１と固定台上面に載置
される回転板２、回転板の上に載置されるボトムケース
３、およびこれらを重ねた状態で結合する２つの結合部
材4,5とネジ６から構成される。The tilt / swivel mechanism includes a fixed base 1, a rotary plate 2 placed on the upper surface of the fixed base, a bottom case 3 placed on the rotary plate, and two connecting members 4 and 5 for connecting these in a stacked state. And screw 6.
回転板２の周辺には、一体で形成された凸部2aが３箇所
に設けられており、ボトムケース３に一体で形成された
凸球面3aと接して摺動面をなす。凸部2aは互いに120度

きる。また、３箇所で保持するため、凸球面3aは必ず３
箇所に接して摺動面は均一に接触し、回転板２に対して
安定することができる。In the periphery of the rotary plate 2, integrally formed convex portions 2a are provided at three locations, and contact the convex spherical surface 3a integrally formed in the bottom case 3 to form a sliding surface. By arranging the convex portions 2a at positions that form an angle of 120 degrees with each other, the weight of the device mounted on the bottom case 3 can be held in a well-balanced manner. Also, the convex spherical surface 3a is always 3 because it is held at 3 points.
The sliding surface comes into uniform contact with the spot and can be stabilized against the rotary plate 2.
なお、本実施例においては、スイーベル動作は固定台１
と回転板２との間でなす１組の凸球面と凹球面とを摺動
面として動作し、本考案を適用した回転板２とボトムケ
ース３との間の摺動面ではチルト動作のみを行なう構造
となっている。In addition, in this embodiment, the swivel operation is performed on the fixed base 1.
A pair of convex spherical surface and concave spherical surface formed between the rotary plate 2 and the rotary plate 2 operate as sliding surfaces, and only the tilting motion is performed on the sliding surface between the rotary plate 2 and the bottom case 3 to which the present invention is applied. It is structured to do.
本考案によれば、摺動面の接触を均一にすることができ
るので、動作がスムーズで静止時の安定性が良好なチル
ト・スイーベル機構が得られる。According to the present invention, since the contact of the sliding surfaces can be made uniform, a tilt / swivel mechanism having smooth operation and good stability at rest can be obtained.
