。[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to robots, machine tools, other mechanical equipment, etc., where power, control signals, gas, water, oil, etc. This invention relates to a flexible support for cables, etc., that supports, protects and guides one or more cables, hoses, etc. for supplying water.

本に結合したものである。Prior art and its problems Conventionally, flexible supports such as cables that supply energy to moving parts in machine tools, etc., have hollow inner frames and surrounding pieces alternately arranged between the fixed end and the moving end. 1) There is a pipe in which cables and the like are housed in a tube that can be bent within a certain range and supported and guided. This is made by arranging two inner frames having grooves of a constant width at equal intervals, and connecting them into a single piece by spanning an enclosing piece having flanges at both ends that fit into the grooves.
また、自在の動きをするものに対する配線は、東線ある

の動きをするものには通用出来ない問題があった。However, the former flexible support such as a cable can be bent horizontally (or vertically) in a plane, but cannot accommodate movement in any direction. That is, although it can be used for moving objects that move in a straight line, it cannot be used for objects that move freely, such as robots.

Also, the method using bellows has many problems, such as not being able to cut and connect, not having a fixed radius, and not being strong enough to support cables, etc.

れている。EXAMPLE Based on FIGS. 6 and 7, the basic structure and operation of the flexible support 5, such as a cable, to which the present invention can be applied will be explained.
This is a hollow link 6 with uneven spherical surfaces on the left and right sides.
It is constructed by continuously coupling. This support 5
A fitting 7 with a flange having a convex spherical surface on both ends of the
and a flanged fitting 8 having a concave spherical surface.

リンク６は球面部において任意の方向にθ度だけ回転可
能であるから一定の屈曲半径を保持しつつ三次元に屈曲
できるものである。The link 6 has an offset shape and has a small diameter protrusion 12 having an inner surface with a concave spherical surface 10 on one cylindrical large diameter portion 9 and an outer surface with a convex spherical surface 1) on the other side, and has a smaller diameter than each of the above spherical surfaces in the elongated direction. A cylindrical hole 13 is provided. Each link is inserted into and engaged with an adjacent link with a concave-convex spherical surface. When the flexible support body 5 is bent, the adjacent concave and convex spherical surfaces of each link are loosely interlocked with each other, so that each link smoothly slides on each other and rotates by θ degrees. When they are rotated by θ degrees, they come into contact with the contact point 14 on the outer diameter portion or the contact point on the inner diameter portion, or both or either one of them, and the stomper mechanism acts. Further, the inner surface of the link 6 is finished smoothly so as not to damage the cables, hoses, etc. 4, and the corners are chamfered. When each link 6 rotates by θ degrees as the flexible body moves, the adjacent links 6 sequentially rotate to form a constant bending radius. Furthermore, since each link 6 can rotate by θ degrees in any direction on the spherical surface, it can be bent three-dimensionally while maintaining a constant bending radius.
なお、リンク６を連結するときは凹球面部を７０℃〜１
００℃の湯水の中に漬し局部的に膨張させ、相手側の凸
球面部を挿入すると簡単にできる。In addition, when connecting the link 6, the concave spherical part should be heated to 70℃~1
This can easily be done by immersing it in hot water at 00°C to expand it locally, and then inserting the convex spherical part on the other side.
次に、本発明によるシール構造の実施例を説明すると、
第１図は、凹球面１０と凸球面１）のうち凸球面の方に
溝１）′を設けてその中に環状シール（Ｏリング）１Ｇ
を入れたものである。Next, an example of the seal structure according to the present invention will be described.
Figure 1 shows a concave spherical surface 10 and a convex spherical surface 1), in which a groove 1)' is provided on the convex spherical surface, and an annular seal (O-ring) 1G is formed therein.
It contains
第２図のものは、第１図と同様の構造であるが、環状シ
ール１６がリンク６の屈曲時、球面より外れない構造と
するために、環状シール両側面に突条１）ａ、ｌｌｂを
もった構造としたものである。The one in FIG. 2 has the same structure as in FIG. 1, but in order to prevent the annular seal 16 from coming off the spherical surface when the link 6 is bent, there are protrusions 1) a, llb on both sides of the annular seal. It has a structure with
また、この突条により浸入しようとする水等の大半の防
水効果も期待できる。In addition, the projecting ridges can be expected to have a waterproofing effect against most of the water that tries to enter.
第３図では、屈曲可能な帯状シール１７をリンク間の軸
方向（長手方向）すきまに外側から取り付は防水機能を
果させている。In FIG. 3, a bendable band-shaped seal 17 is attached from the outside to the axial (longitudinal) gap between the links to achieve a waterproof function.
次に、第４図のものでは、柔軟な環状シール１８又は１
８′をリンク間の外側の軸方向すきま又は内側の軸方向
すきまに連結時に組込み、防水可能な構造としている。Next, in the one of FIG. 4, a flexible annular seal 18 or 1
8' is incorporated into the outer axial gap between the links or the inner axial gap when the links are connected, resulting in a waterproof structure.
このシールは、組込んだ状態にて圧縮状態になるように
しておけば、リンクの屈曲の程度が少なければ充分シー
ル効果を奏することができる。If this seal is made to be in a compressed state in the assembled state, a sufficient sealing effect can be achieved as long as the degree of bending of the link is small.
最後に第５図のものは、シールを用いないもので、凸球
面１）に環状突起１）ｃ、ｌｉｄを出し凹球面１０とタ
イトフィツトに設面して凹凸球面の接触面積を小さくし

のである。Finally, the one in Fig. 5 does not use a seal, and the annular protrusion 1) c and lid are provided on the convex spherical surface 1) and are set in a tight fit with the concave spherical surface 10 to reduce the contact area of the concave and convex spherical surfaces and bend. It has a waterproof structure while ensuring smooth movement.
この場合、隙間はほとんどＯあるいは少しタイトフィツ
トにして外部からの水等の浸入を防ぐ。In this case, the gap is almost O or slightly tight fit to prevent water from entering from the outside.
この突起ｔｔｃ、ｔｔｃｔは凹球面１０側に設けてもよ
い。The protrusions ttc and ttct may be provided on the concave spherical surface 10 side.
なお、図示したリンクの形状は一具体例にすぎず、各種
の変形があることは先の出願に記載しているとおりであ
る。It should be noted that the shape of the link illustrated is only one specific example, and as described in the previous application, there are various modifications.
