特徴とする。The device according to the invention is a remotely controllable device for fixing a fixing screw whose head and part of the body are held outside a clamping member, the device being provided with an annular recess arranged around the screw. said recess has a single opening in the direction of the head of the screw partially obstructed by a shoulder and a spring at its bottom, and further has another shoulder and a fixed support on its inner surface. a movable member having means capable of cooperating with the threadedly supported ring means by a complementary shape, the movable member being mounted within said recess and compressing the spring and releasing the ring therein; and a fixed position in which both shoulders are in contact and the movable piece means cooperates with the ring means;
It is characterized by moving translationally but non-rotationally in the axial direction.
本明細書において、バネは可動部材の変位を可能にする
ように弾性変形しうる任意の手段、特に慣用のバネを意
味すると理解される。A spring is understood herein to mean any means capable of being elastically deformed so as to allow a displacement of a movable member, in particular a conventional spring.
前記可動部材は前記環状凹部内で非回転的に「摺動」し
て、装置の回転を確実に阻止する。The movable member "slides" non-rotationally within the annular recess to positively prevent rotation of the device.
これは任意の手段、特に可動部材の外面の形状と支持体
におけるショルダーの内面の形状の特異性によって得る
ことができ、これらの形状は固定位置にて対向する。This can be obtained by any means, in particular by the specificity of the shape of the outer surface of the movable member and the shape of the inner surface of the shoulder in the support, which shapes are opposed in the fixed position.
可動部材の外面は、環状凹部内で抗トルクの役割を果す
ようにされねばならない。前記可動部材および前記ショ
ルダーのそれぞれ外面および内面は多角形、特に六角形
、正方形などとすることができる。The outer surface of the movable member must be adapted to play an anti-torque role within the annular recess. The outer and inner surfaces of the movable member and the shoulder, respectively, may be polygonal, in particular hexagonal, square, etc.
さらに、回転阻止は他の手段により、特にピン型システ
ムにより得ることができる。Furthermore, rotational arrest can be obtained by other means, in particular by a pin-type system.
固定位置において、ネジと可動部材は、それぞれネジに
より支持されたリングおよび可動部材の内面に位置する
手段によって接続される。In the fixed position, the screw and the movable member are connected by a ring supported by the screw and means located on the inner surface of the movable member, respectively.
これらの手段は相補的形状により連携する。有利には、
この手段は溝部またはその均等物であるのが好ましい。These means cooperate by means of complementary shapes. Advantageously,
Preferably, this means is a groove or its equivalent.
これらは固定位置にて互いに嵌合し、かつたとえばネジ
を捩る際にリングを解除させかつネジと可動部材との連

この種の変位を行うには、ネジの軸に沿って可動部材に
圧力を加えれば充分である。To effect a displacement of this kind, it is sufficient to apply pressure to the movable member along the axis of the screw.
本発明による装置の支持部は任意のフレーム、特にクラ
ンプすべき部品の少なくとも１つの表面に固定すること

したがって、これはたとえば遠隔操作機、ロボットなど
により完全に遠隔操作に適し、したがって人間が接近し
えない領域、たとえば放射能領域に有利に使用すること
ができる。It is therefore completely suitable for remote control, for example by remote control machines, robots, etc., and can therefore be used advantageously in areas inaccessible to humans, for example radioactive areas.
さらに、軸を任意の方向、特に水平面、垂直面、傾斜面
に配向させたネジについても用いうろことが注目されよ
う。Furthermore, it will be noted that screws with their axes oriented in any direction, especially horizontal, vertical or inclined planes, may also be used.
以下、添付図面を参照して本発明による装置を実施例に
つき一層詳細に説明する。In the following, embodiments of the device according to the invention will be explained in more detail with reference to the accompanying drawings.

設けられる。The assembly means is a clamp 5, and its tightening is done by a block 7.
It is adjusted by a screw 6 acting simultaneously on the top. Said block slides along the screw, thus causing a movement in the positioning direction of the clamp surrounding the parts 1 and 2 or in the opposite direction. In order to accurately guide the leg 8 of the screw, a quadrilateral 9 is provided on the outer surface of the part 2 that comes into contact with the screw.
部品１および２をその表面３，４により互いに接触させ

の圧力が得られるまで緊締を続ける。The clamp and screw are installed so that the parts 1 and 2 are in contact with each other by their surfaces 3, 4 and the clamp surrounds these parts. The screw is then tightened with its head 10, the block 7 is raised, thus bringing the clamp leg 11 and the screw leg 8 into contact with the parts 1, 2, and tightening is continued until the desired pressure is obtained.
この装置およびその操作は完全に周知のものである。This device and its operation are completely known.
本発明によれば、このようにして得られた組立体を固定

ルダー１９の幅よりも若干大である。The support part 12 includes a member 15 arranged around the screw,
An annular recess 16 is arranged here so that its axis of rotation coincides with the axis of rotation of the screw. The fourth part 16 has only one opening in the direction of the head of the screw 10. This opening does not occupy the entire surface of the recess, but is partially closed by the shoulder 17 of the support. A movable member 18 freely slides on these four parts, and this movable member is provided with a shoulder 19 to prevent this member from coming off from the recess when it comes into contact with the shoulder 17. The width of the four parts is slightly larger than the width of the shoulder 19 to ensure sliding movement.

溝部が歯付き部分２０を形成するようにし、この歯付き
部分はネジにより支持される、同寸法の溝部を同様に設
けたリング２１に嵌合することができる。The inner surface of the member 18 (opposite the screw) is provided with a groove such that the groove forms a toothed portion 20, which toothed portion is supported by the screw and is a ring similarly provided with a groove of the same size. 21.
リング２１の変位はネジによって調節される。The displacement of ring 21 is adjusted by a screw.

部の底部に設けたバネ２３がネジ脚部の方向への変位を
緩衝する。The displacement of the movable member 18 is independent of the screw. This is adjusted by the force applied by the operator to the surface 22 of the movable member 18 (ie, the surface facing the screw head). A spring 23 provided at the bottom of the recess cushions displacement in the direction of the screw leg.
操作員が圧力を解除すると、可動部材１８はバネの作用
下で反対方向に移動して四部のショルダー１７に当接す
る。When the operator releases the pressure, the movable member 18 moves in the opposite direction under the action of the spring and abuts the four-part shoulder 17.

よびバネの長さはこのデータから選択される。During these displacements, the toothed portion of the movable member comes into contact with the toothed ring or moves away from it. The stroke length of the movable member in the recess is such that this contact and non-contact between the toothed members is possible. The recess and spring lengths are selected from this data.

る。この操作に際しネジをその軸に維持するには、停止
部２６を設けてこれを支持部に接触させる。During screw operation, the operator applies pressure against the surface 22 of the movable member 18 to separate the toothed portion 20 from the ring 21. The screw released in this way is tightened, but it is possible to prevent the movable member from rotating during this operation.
(role of anti-torque), which is obtained by a suitable external shape (hexagonal in this example) and by the same shape of the opposing support surface. In FIG. 1, it is a matter of the outer surface 24 of the movable member and the inner surface 25 of the shoulder 17. To maintain the screw on its axis during this operation, a stop 26 is provided which contacts the support.

固定が得られ、ネジ弛緩の可能性が防止される。By stopping the screw operation, the operator releases the pressure on the movable member 18. Under the action of the spring 23, which is thus relaxed, the movable member 18 rises until the shoulders 17 and 19 abut. Thus, the ring 21 and the toothed member 20 come into contact. The mating groove thus prevents lateral movement (ie movement perpendicular to the axis of rotation of the screw). Fixation is thus obtained and the possibility of screw loosening is prevented.
ショルダー１７．１９が当接するので、この接触はもは
やネジヘッド方向への可動部材の変位によって崩しえな
い。Since the shoulders 17,19 abut, this contact can no longer be broken by a displacement of the movable member in the direction of the screw head.
