Description

  The present invention relates to a machine tool, industrial robot, etc., such as a cable for transmitting electric power or a control signal between a fixed part and a movable part in an apparatus in which the movable part repeatedly moves linearly within a predetermined range with respect to the fixed part, or The present invention relates to a movable body long body used as a pipe for supplying air pressure or the like, in a state where bending is partially restricted.

  In machine tools, industrial robots, etc., it is a mechanism that performs complex work such as processing, conveyance, mounting, etc. using a mechanism part that moves relative to the fixed device body, and the mechanism part that performs such work is Although it is a movable part that moves within a predetermined range with respect to the fixed apparatus main body, in order to properly operate various mechanisms provided in such a movable part, there is a gap between the movable part and the fixed apparatus main body. They are connected by cables for supplying electric power and transmitting control signals, pipes for supplying hydraulic pressure and air pressure, and the like.

  In such a device, although the cable, tube, etc. provided between the movable part and the fixed part have moderate flexibility and need to follow the movement of the movable part, they move randomly. Therefore, since it must be avoided that the operation of the apparatus is hindered, a protection guide guide that keeps the movement of such cables in an appropriate state has been proposed. One example is disclosed in Japanese Patent Application Laid-Open No. 2003-83473.

  The conventional protective guide guide includes a flexible tube made of a synthetic resin that encloses a plurality of cables and is connected to a cable moving end portion and a cable fixed end portion, and is enclosed and fitted to the flexible tube at a predetermined interval. It is the structure which has many bending | flexion control units provided united.

  In recent years, there has been proposed a cable that can maintain a state of moving on a certain track without any problem without using such protection guides for the cables. No. 259658 and JP-A-2009-259659.

  The conventional protective guide guide has a configuration shown in Patent Document 1, and the protective guide guide can move within a certain movement region while maintaining a predetermined extension posture and bending posture. By moving cables, tubes, and the like through the guide, it is possible to appropriately regulate the moving regions of these cables, tubes, and the like.

  However, since the cost of the apparatus increases due to the use of a separate protection guide guide other than the cable, the bending guide units abut against each other due to the movement of the protection guide guide accompanying the movement of the movable part, and the contact parts wear out. As a result, there was a problem that dust was generated. In addition, there has been a problem that noise is generated when the bending regulating units repeat contact and separation with each other.

  On the other hand, the conventional cables shown in Patent Documents 2 and 3 are advantageous in terms of dust and noise because the protective guide is not used, but the parallelism in the U-shaped parallel portion of the cable in the state of use is improved. As a result of adjusting the flexibility of the entire cable in order to make it possible to maintain the cable, it becomes difficult to cause a smooth bending at a position where it should be bent during movement, and the structure inside the cable is complicated and specialized. For this reason, there is a problem that the cable manufacturing cost increases.

  The present invention has been made to solve the above-mentioned problems, and an unintended unnecessary bending does not occur without using a protective guide guide, and it can be easily bent in the direction to be bent, and can move a movable part. It aims at providing the elongate body for movable parts which does not give trouble.

  The movable body elongate body according to the present invention has one or more core wires and / or tubes and one or more flexible cable portions and a part of the outer periphery of the cable portion. The block body is arranged in a large number of closely arranged in the longitudinal direction of the cable portion, and the block body is combined with the block body while at least restraining the movement of the block body in the width direction perpendicular to the longitudinal direction of the cable portion. And one or a plurality of restraining portions that are extended from the combined block body toward the other block body adjacent on one side in the longitudinal direction of the cable portion, and each block body, A concave portion or a hole that allows insertion of the restraint portion extended from another adjacent block body on the other side in the longitudinal direction of the cable portion is drilled, and the restraint portion is extended from the combined block body, Other bro next to you The state of being inserted into the recess or hole in the click member, is that formed as an extension length that even after the relative movement enables maintenance to the other block of the block body due to the bending deformation of the cable portion.

  As described above, in the present invention, a plurality of block bodies are cabled with respect to a cable portion containing a core wire through which electricity or light passes as an operating element and / or a pipe through which air, hydraulic oil or the like passes as an operating element. While arranged side by side in the longitudinal direction of the part, a restraint part combined with the block body is provided, and bending such that the cable part is on the inner side of the block body is prevented by contact between the block bodies, Bending such that the cable part is on the outside where the block body exists is allowed without being affected by the block body, so that the cable part receives external force and bends only in the direction where the side on which the block body exists is outside. Even without using a protective guide or the like, an unintended unnecessary bending does not occur during the movement of the one end of the movable body long body within a predetermined movement area, and the U-shape is viewed from the side. Condition While maintaining the bent form, the movement of the end portion can be stably performed. Also, not only in the state where the cable part is not bent, but also in the bent state, the restraint part extended from the block body maintains the inserted state to the other block body next to another block adjacent to the block body. By making it difficult for deviations other than relative movement due to bending of the cable part of the body, it is possible to prevent deformation of the entire block body in the lateral direction other than the direction of bending of the cable part, and deformation other than the preset bending Without causing the cable portion, the behavior of the cable portion can be made stable without rolling or meandering.

  Further, in the movable body elongate body according to the present invention, if necessary, the constraining portion is formed integrally with the block body, and a protruding shape in which a portion extended toward another adjacent block body protrudes. Each block body has a recess in the other side of the cable portion in the longitudinal direction, and the recess is always inserted at least part of the convex portion of the restraint portion, and the cable portion is linear. In the state where the block bodies are brought close to each other by extending in the direction, the concave portion is fitted with the convex portion.

  As described above, in the present invention, the constraining portion is formed integrally with the block body, and the convex portion is not only inserted into the concave portion drilled in the other adjacent block body, but the cable portion is straight. In a portion that is not bent as a shape, the protruding portion of the restraining portion protruding from the block body is adjacent to the other adjacent portion regardless of the bending state of the cable portion by fitting the protruding portion into the recessed portion. Maintains the insertion state in the block body, makes it difficult to cause a shift other than relative movement due to the bending of the cable part of another block body adjacent to the block body, and deforms in the lateral direction other than the direction in which the cable part bends In addition to preventing the cable portion from being bent as a straight line, the block bodies are connected together so as not to be displaced, and the straight portion of the cable portion adopts a U-shaped bent form. For it, easier to maintain the linear shape, can be further stabilized behavior of the cable portion.

  Further, in the movable body elongate body according to the present invention, if necessary, each block body is provided with a hole penetrating in the longitudinal direction of the cable portion, and the restraining portion is continuous in the longitudinal direction of the cable portion. All of the block bodies are formed into elongate linear bodies or strips that can be bent along the section, and are passed through the holes of each block body to allow relative movement in the longitudinal direction of the cable section of the block body with respect to the restraining section. Are combined.

  As described above, in the present invention, the constraining portion is a linear body or a belt-like body separate from the block body, and is combined with each block body in a state of passing through the holes of all the block bodies, and is combined with a predetermined block body. As the restraint portion is inserted into the hole in the other adjacent block body, a deviation other than relative movement due to bending of the cable portion of the other block body adjacent to the predetermined block body is less likely to occur. Therefore, regardless of the bending state of the cable part, a series of block bodies passed through the restraining part can prevent deformation in a lateral direction other than the direction in which the cable part is bent, In addition to being able to stabilize the behavior of the cable part without causing any deformation other than the cable part, each block body is connected by the restraint part, so that the predetermined block body and cable Even if the integrated state with the outer periphery breaks and the block body and the cable part try to separate, the block body can maintain the positional relationship with other block bodies, and it will not fall off from the outer periphery of the cable part. In addition, there is no influence on the moving operation of one end of the movable part long body and the movement and deformation of each part of the movable part long body.

  In addition, the movable body elongate body according to the present invention is provided with another constraining part that is different from the constraining part that is a linear body or a belt-like body, and is formed integrally with the block body. The portion extending toward the block body has a protruding convex shape, each block body has a recess in the other side of the cable portion in the longitudinal direction, and the recess is a protrusion of another restraining portion. In a state in which the shape portion is always inserted and the cable portions are linearly extended to bring the block bodies closest to each other, the concave portion is fitted to the convex shape portion.

  As described above, in the present invention, a constraining portion different from the constraining portion to be a linear body or a band-shaped body is formed integrally with the block body, and the convex portion is drilled in another adjacent block body. Not only in the insertion state with respect to the concave part, but also in the part where the cable part is not bent as a straight line, the convex part becomes the fitting state into the concave part, so that the block regardless of the bending state of the cable part. The convex part of the restraining part that protrudes from the body maintains the insertion state in the other block body next to it, and makes it difficult to cause a deviation other than the relative movement due to the bending of the cable part of the other block body adjacent to the block body. In addition to preventing deformation in the lateral direction other than the direction in which the cable part bends, in the part where the cable part is not bent as a straight line, the block bodies are connected together so that they do not shift and become U-shaped. Condition For linear portion of the cable portion taking the bending form, it is easy to maintain the linear shape, it can be further stabilized behavior of the cable portion.

  In addition, the movable body elongate body according to the present invention, if necessary, each block body at one end in the longitudinal direction of the cable part, with the part away from the outer periphery of the cable part partially cut out, The first stepped part with a step in the longitudinal direction of the cable part and the end on the other side in the longitudinal direction of the cable part, with the part near the outer periphery of the cable part partially cut away, In the first stepped portion, a stepped surface portion that is closer to the outer periphery of the cable portion due to the notch is provided. In the second stepped portion of another adjacent block body, the stepped surface portion that is separated from the outer periphery of the cable portion with the notch is always facing, and the cable portion is linearly extended to block A state where the bodies are closest Is to contact overlaps the stepped surface portions of the cable portion near the outer periphery, and stepped surface portion remote from the cable outer circumference of said another block body.

  Thus, in the present invention, the one end and the other end in the longitudinal direction of the cable portion of the block body are partially cut away, and the block body is separated from the cable portion outer periphery and the cable portion outer periphery. In addition to forming a stepped part in each part on the side and arranging the first stepped part of the block body so as to always face the second stepped part in the other adjacent block body, the cable In the part where the part is not bent as a straight line, the stepped parts are in close contact with each other, so that in the bent part of the cable part, the first stepped part of the block body is the second part in the adjacent other block body. Deviations other than relative movement associated with the bending of the cable part of the other block body adjacent to the block body while maintaining the facing state with the second stepped part, especially the bending of the cable part bent in an arc shape In addition to making it difficult for radial deviation from the center to occur and obtaining a state where the bent portion of the cable portion is bent evenly without distortion, in a portion where the cable portion is not bent as a straight line, the stepped portion of the block body They are in close contact with each other and restrain the positional relationship of the block body with respect to the cable outer periphery, that is, the vertical displacement of other block bodies adjacent to the predetermined block body is suppressed, and the cable body as a whole block body The straight portion can be prevented from being deformed in the vertical direction, so that the straight shape of the cable portion can be reliably maintained, and the behavior of the cable portion can be further stabilized. Furthermore, the first stepped portion of the block body always maintains the facing state with the second stepped portion in the other adjacent block body, and the block bodies are in a fixed restraint state, The integrated connection between the block body and the cable part outer periphery can be strengthened to make it difficult to break. If the predetermined block body and cable part outer periphery are broken, the block body and the cable part will be separated. The block body can maintain the positional relationship with the other block bodies even if it reaches the situation, and it does not fall off from the outer periphery of the cable part. There is no effect on the movement and deformation of each part of the long body.

  Further, the movable body long body according to the present invention is rounded while maintaining a state in which the distal end portion of the convex portion of the restraining portion and the innermost portion of the block body concave portion can be fitted to each other as necessary. It is formed in a tinged shape.

  Thus, in the present invention, the tip of the convex portion of the restraining portion is formed in a rounded shape, and the innermost portion in the concave portion of the corresponding block body is also rounded, so that the cable portion When the convex part is in a state where it is not bent as a straight line, the rounded tip of the convex part is in contact with the rounded innermost part of the concave part. As a result, the contact between the tip of the convex part and the innermost part of the concave part in the fitting between the convex part and the concave part is smooth and does not generate an impact, and noise is generated in the fitting between the convex part and the concave part. Each block body that moves with the fitting of the convex part and the concave part while the position of the bent part or the linear part of the cable part changes during the movement operation of the one end part of the long part for the movable part. Greatly reduces noise It can be.

(First embodiment of the present invention)
Hereinafter, the movable body long body according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
In each said figure, the elongate body 10 for movable parts which concerns on this embodiment is equipped with the several cable parts 11, 12, 13, 14 which have one or more core wires and / or tubes, and have flexibility, and In addition, a block body 15 that is arranged in a dense manner in the longitudinal direction of the cable portion in a state of being connected and integrated with a part of the outer periphery of the cable portions 11, 12, 13, and 14, and formed integrally with the block body 15 And a convex portion 16 as the restraining portion projecting to one side in the longitudinal direction of the cable portion.

  The cable portions 11, 12, 13, and 14 are each an elongated member for operation that allows the operation element to pass through, that is, the core wires 11a, 12a, 13a that transmit electricity and light as the operation element, and / or as the operation element. One or a plurality of tubes 14a through which air or hydraulic oil passes are covered with sheaths 11b, 12b, 13b, 14b. These four cable parts 11, 12, 13, and 14 formed in a circular cross-sectional shape are juxtaposed in a substantially strip shape, and are connected and integrated with each other. In addition, when using what has a pipe | tube as a cable part, a sheath may be abbreviate | omitted and you may make it connect and integrate with another cable part and a block body as a pipe | tube directly as a cable part.

  Since these cable parts 11, 12, 13, and 14 are arranged side by side and connected and integrated, they are easy to bend in a direction perpendicular to the direction in which the cable parts are arranged in parallel, and difficult to bend in other directions. It has become.

  The block body 15 is formed of a material harder than the cable portions 11, 12, 13, and 14, and is adjacent to any of the four cable portions 11, 12, 13, and 14 arranged in parallel. In addition, it has an appropriate height dimension that provides rigidity that does not easily deform, and is configured to be integrally connected to the outer periphery of the cable portions 11, 12, 13, and 14 in a large number. The corner portions of the connecting surfaces that are integrally connected to the cable portions 11, 12, 13, and 14 of the block body 15 are notched, and the outer peripheries of the cable portions 11, 12, 13, and 14 that repeatedly bend and extend. A state in which stress is applied to the surface from the corners of the block body 15 can be avoided.

  By arranging a large number of block bodies 15 in the cable portions 11, 12, 13, and 14 to restrict bending, the direction other than the direction in which the block bodies 15 of the cable portions 11, 12, 13, and 14 are present is outside. The cable portions 11, 12, 13, and 14 are bent only in a direction in which the side on which the block body 15 exists is outside. However, the bent portions of the cable portions 11, 12, 13, and 14 will be maintained at a predetermined curvature with the rigidity of the entire cable portions 11, 12, 13, and 14, preventing unintentional excessive bending and stabilizing the bent portions. Can be held in the same state.

  A convex portion 16 as the restraining portion is formed in a projecting convex shape and disposed integrally with the block body 15 at one portion of the block body 15 in the longitudinal direction of the cable portion. Further, in the block body 15, a concave portion 17 into which the convex portion 16 of another block body can be inserted is formed in the other side portion of the cable portion in the longitudinal direction.

  The concave portion 17 has a groove-like concave shape that does not constrain the convex portion 16 in the block body thickness direction that is perpendicular to the cable portion longitudinal direction and the cable portion side-by-side direction (block body width direction). . And the said convex part 16 is extended from the integral block body 15 to the one side of the cable part longitudinal direction, and is in the state inserted in the recessed part 17 in another adjacent block body with bending deformation of a cable part. The block body 15 is formed to have a sufficient length that can be maintained even after a relative movement with respect to the other block body. That is, the concave portion 17 is in a state where the convex portion 16 is always inserted. Moreover, in the state which extended the cable part linearly and made the block bodies 15 mutually approach, the recessed part 17 will fit with the convex part 16, and the block bodies 15 will be connected.

  Although the movable body elongate body 10 according to the present embodiment is finally used in an integrated state with the cable parts 11, 12, 13, and 14 and the block bodies 15 respectively adjacent thereto, There is no particular limitation on the method of integrating the cables, and the cable sections 11, 12, 13, and 14 are arranged in parallel and integrated, and then the block bodies 15 are connected and arranged, and each cable section is one by one. A plurality of small block bodies having a width of about the outer diameter of the cable portion arranged and integrated in the longitudinal direction of the cable are arranged in parallel later to obtain a substantially band-shaped cable portion, and the small block body is a cable. It is also possible to obtain a block body integrated in the juxtaposed direction.

  Next, a use state of the movable body long body according to the present embodiment will be described. The movable part elongate body 10 is disposed in a predetermined region in a state bent in a U-shape (see FIG. 1). One end of the movable part elongate body 10 is a moving end, and the other end is a fixed end, and the position of the bent portion changes corresponding to the movement of the moving end. At this time, even if an external force or the like tries to bend the cable portions 11, 12, 13, 14 so that the side where the block body 15 exists is inside, the block bodies 15 abut against each other in the longitudinal direction of the cable portion and move relative to each other. Without bending, bending of the cable portions 11, 12, 13, and 14 is prevented.

  On the other hand, when the cable portions 11, 12, 13, and 14 corresponding to the state bent in the U-shape are bent so that the side where the block body 15 exists is outside (see FIGS. 1 and 3). ), The block body 15 can move relative to each other in the longitudinal direction of the cable portion, and does not become an obstacle to bending, and the cable portions 11, 12, 13, and 14 can be bent. As a result, the cable portions 11, 12, 13 and 14 are bent only in the direction in which the side where the block body 15 exists is the outside. In this way, during the movement operation of the moving end of the movable part long body 10, unintended unnecessary bending does not occur in each part of the movable part long body 10, and the movement operation is performed stably.

  Further, in each block body 15, the convex portion 16 formed integrally with the block body 15 is always inserted into the concave portion 17 formed in another adjacent block body, and in particular, the cable portions 11, 12. , 13, and 14 are not bent in a straight line, and the convex portion 16 is in a fitted state with the concave portion 17. Thereby, regardless of the bent state of the cable parts 11, 12, 13, 14, the cable part is bent by another block body adjacent to the predetermined block body 15 by the restraint by the convex part 16 and the concave part 17. Deviations other than relative movement, in particular, deviations in the block body width direction that coincide with the cable portion juxtaposition direction are less likely to occur.

  Based on the difficulty of shifting between the block bodies, it is possible to prevent deformation of the cable portions 11, 12, 13, and 14 in the lateral direction other than the bending direction. Further, in the portion where the cable portions 11, 12, 13, and 14 are not bent as a straight line, the block bodies 15 are integrally connected to each other so as not to be displaced, and the moving operation of the moving end of the movable portion long body 10 is performed. At the time, the straight portions of the cable portions 11, 12, 13, and 14 adopting the U-shaped bent form can be easily maintained, and the behavior of the cable portions 11, 12, 13, and 14 can be stabilized. .

  As described above, in the movable body elongate body according to the present embodiment, a plurality of block bodies 15 are arranged in the longitudinal direction of the cable portion with respect to the cable portions 11, 12, 13, and 14 incorporating the core wire and / or the tube. In addition to arranging them side by side, the protrusions 16 that are integral with the block bodies 15 are provided, and the bends such that the cable portions 11, 12, 13, 14 are on the side where the block bodies 15 exist are in contact with each other. On the other hand, the cable portions 11, 12, 13, 14 are allowed to be bent with the side where the block body 15 exists outside as the cable body 11, 12, 13, 14 is not affected by the block body 15. , 13 and 14 receive an external force and are bent only in the direction in which the side on which the block body 15 exists is outside. Even without using a protective guide guide, For movement And unnecessary bending does not occur unintentionally, while maintaining the U-shaped bent form as viewed from the side, the movement of the movable end can be stably performed. Further, not only in a state where the cable portions 11, 12, 13, and 14 are not bent, but also in a bent state, the convex portion 16 extended from the block body 15 is inserted into the concave portion 17 of another adjacent block body. The direction in which the cable portions 11, 12, 13, and 14 are bent as a whole of the block body 15 by maintaining and making it difficult to cause a shift other than relative movement due to the bending of the cable portion of another block body adjacent to the block body 15. It is possible to prevent deformation in the lateral direction other than the above, and the cable portions 11, 12, 13, and 14 accompanying the movement operation are not caused in the cable portions 11, 12, 13, and 14 without causing deformation other than the preset bending. Can be made stable without rolling or meandering. In addition, the installation space can be further reduced by the amount that the protection guide guide is unnecessary, and the cost required for the protection guide guide can be reduced.

  In addition, in the elongate body for movable parts which concerns on the said embodiment, the four cable parts 11, 12, 13, and 14 are arranged in parallel in substantially strip | belt shape, and this cable part 11, 12, 13, 14 arranged in parallel is arranged. However, the present invention is not limited to this, and the configuration may be such that only one cable portion is provided, or the cable portions are provided in parallel as a plurality other than four. . In addition, when a plurality of cable portions are arranged in parallel, the block body is adjacent to all the cable portions. However, the present invention is not limited to this, and a part of the plurality of cable portions arranged in parallel, for example, three out of four Alternatively, the block body may be disposed adjacent to only the outer periphery of the cable portion. In addition, there is nothing limited to a configuration in which a plurality of cable portions arranged in parallel are used as a circular cross-sectional shape of the same outer diameter, and some or all of the outer diameters of the plurality of cable portions are arranged in parallel, these Can be configured to be connected and integrated with the block body.

  Moreover, in the elongate body for movable parts which concerns on the said embodiment, while making the front-end | tip part of the convex part 16 provided as a restraint part into the shape which combined the plane, the other side of the cable part longitudinal direction in the block body 15 The innermost portion of the concave portion 17 formed in the portion is also configured to have a shape combining planes. However, the present invention is not limited to this, and as shown in FIG. And the innermost part of the concave portion 19 of the block body 15 can be formed in a rounded shape while maintaining a state where they can be fitted to each other, and the cable portions 11, 12, 13, 14 can be formed. When the convex portion 18 is fitted to the concave portion 19 at a portion that is not bent as a straight line, the rounded tip portion of the convex portion 18 contacts the rounded innermost portion of the concave portion 19. Thus, the convex portion 18 and the concave portion 19 The contact between the tip of the convex portion 18 and the innermost portion of the concave portion 19 in the fitting is smooth and does not generate an impact, and noise is hardly generated in the fitting between the convex portion 18 and the concave portion 19, and the length for the movable portion Each block that moves while fitting the convex portion 18 and the concave portion 19 while the position of the bent portion or the linear portion of the cable portion 11, 12, 13, 14 changes during the movement operation of the one end portion of the scale body. Noise generated from the body 15 can be greatly suppressed.

  Similarly to the first embodiment, the cable portions 21, 22, 23, and 24 are long members for operation that allow the operation elements to pass through, that is, the core wires 21a, 22a, and 23a that transmit electricity and light as the operation elements. And / or the pipe | tube 24a which lets air and hydraulic oil as an operation | movement element pass is covered with sheath 21b, 22b, 23b, 24b, and is the structure which incorporates one or more. These four cable portions 21, 22, 23, and 24 are arranged in parallel in a substantially band shape, and are connected to each other and integrated as in the first embodiment. When a cable having a tube is used, as in the first embodiment, the sheath is omitted and the tube is directly connected to another cable portion or block body as a cable portion. Good.

  The block body 25 is a rectangular block formed of a material harder than the cable portions 21, 22, 23, and 24, and is adjacent to any of the four cable portions 21, 22, 23, and 24 arranged side by side. It has a width and an appropriate height that provides rigidity that does not easily deform, and is configured to be integrally connected to the outer periphery of the cable portions 21, 22, 23, 24. By providing a large number of block bodies 25 in the cable portions 21, 22, 23, and 24 to restrict bending, the cable portions 21, 22, 23, and 24 are present in the presence of the block body 25 as in the first embodiment. It will be bent only in the direction that the outside is the outside.

  A hole 26 penetrating in the longitudinal direction of the cable portion is formed in the block body 25, and a linear body 27 as the restraining portion is passed through the hole 26 so as to be movable in the longitudinal direction of the cable. And the linear body 27 is passed through all the block bodies 25, and each block body 25 is connected via the linear body 27, so that the predetermined block body 25 and the cable portions 21, 22, 23, 24 are temporarily provided. Even if the integrated state with the outer periphery is broken and the block body 25 and the cable parts 21, 22, 23, 24 are about to be separated, the block body 25 can maintain the positional relationship with other block bodies, This is a mechanism that does not fall off from the outer periphery of the cable portions 21, 22, 23, and 24.

  The linear body 27 is an elongated flexible material that is continuous in the longitudinal direction of the cable portion and can be bent along the cable portion, and is passed through the hole 26 of each block body 25 to block the linear body 27. The structure is combined with all the block bodies 25 while allowing the relative movement of the body 25 in the longitudinal direction of the cable portion.

  By combining the linear body 27 with each block body 25 in a state of passing through the holes 26 of all the block bodies 25, the linear body 27 as a restraint portion combined with the predetermined block body 25 can be The relationship which will be in the insertion state in the hole 26 in this block body is materialized. This means that a shift other than the relative movement in the longitudinal direction of the cable portion due to the bending of the cable portion of another adjacent block body is less likely to occur with respect to the predetermined block body 25 due to the intervention of the linear body 27. To do. In this way, regardless of the bending state of the cable portions 21, 22, 23, 24, a series of block bodies 25 whose displacement is regulated by passing through the linear body 27 are connected to the cable portions 21, 22, 23, 24. This acts to prevent deformation in the lateral direction other than the direction of bending.

  Next, a use state of the movable body long body according to the present embodiment will be described. Like the first embodiment, the movable part long body 20 is disposed in a predetermined region in a bent state in a U-shape, with one end thereof serving as a moving end and the other end serving as a fixed end. The position of the bent portion is changed corresponding to the movement of the moving end. At this time, even if an external force or the like tries to bend the cable parts 21, 22, 23, 24 so that the side where the block body 25 exists is inside, the block bodies 25 abut against each other and do not move relative to each other. Bending of 21, 22, 23, 24 is prevented.

  On the other hand, when the cable portions 21, 22, 23, 24 corresponding to the state bent in the U-shape are bent so that the side where the block body 25 exists is outside, the block body 25 is a cable. The cable portions 21, 22, 23, and 24 can be bent, and the cable portions 21, 22, 23, and 24 can be bent. As a result, the cable portions 21, 22, 23, and 24 are bent only in the direction in which the side where the block body 25 exists is the outside. In this way, during the movement operation of the moving end of the movable part long body 20, unintended unnecessary bending does not occur in each part of the movable part long body 20, and the movement operation is performed stably.

  In each block body 25, the linear body 27, which is separate from the block body 25, is combined through the hole 26 of the block body 25, and is always inserted into the holes in the other adjacent block bodies. Have gained. As a result, regardless of the bending state of the cable portions 21, 22, 23, 24, the presence of the linear body 27 becomes an obstacle, and the bending of the cable portion of another block body adjacent to the predetermined block body 25 Therefore, it is difficult to cause a shift other than the relative movement, particularly a shift in the block body width direction that coincides with the cable portion juxtaposition direction. Based on the difficulty of shifting between the block bodies 25, it is possible to prevent the cable portions 21, 22, 23, 24 from being deformed in a lateral direction other than the bending direction.

  As described above, in the movable body long body according to the present embodiment, the restraining portion is a separate linear body 27 from the block body 25, and the linear body 27 is passed through the holes 26 of all the block bodies 25. In combination with each block body 25, the linear body 27 combined with the predetermined block body 25 is inserted into the hole 26 in another adjacent block body, and the predetermined block body is established. Since it is difficult for unnecessary displacement of other block bodies adjacent to 25 to occur, a series of block bodies passed through the linear body 27 regardless of the bending state of the cable portions 21, 22, 23, 24. 25 prevents the cable portions 21, 22, 23, 24 from deforming in a lateral direction other than the direction in which the cable portions 21, 22, 23, 24 are bent, and does not cause the cable portions 21, 22, 23, 24 to undergo deformation other than the preset bending. ,cable Behavior of 21, 22, 23, 24 and can be provided with stable.

(Third embodiment of the present invention)
A long member for a movable part according to a third embodiment of the present invention will be described with reference to FIGS.
In each said figure, the elongate body 30 for movable parts which concerns on this embodiment is equipped with the several cable parts 31, 32, 33, 34 which have one or more core wires and / or tubes, and have flexibility, and A thin flat belt-like sheet body 35 connected and integrated with a part of the outer periphery of the cable parts 31, 32, 33, and 34, and connected and integrated with the surface of the sheet body 35. In this state, a plurality of block bodies 36 arranged densely in the longitudinal direction of the cable portion, and a convex portion 37 as the restraint portion formed integrally with the block body 36 and projecting on one side in the longitudinal direction of the cable portion. And a linear shape as the constraining part different from the convex part 37, which is arranged in combination with all the block bodies 36 through a hole 38 penetrating in the longitudinal direction of the cable part of each block body 36. And a body 39.

  As in the first embodiment, the cable portions 31, 32, 33, and 34 are long working materials for passing the working elements, that is, the core wires 31a, 32a, and 33a that pass electricity and light as the working elements. And / or the pipe | tube 34a which lets air and hydraulic oil as an operating element pass is covered with sheath 31b, 32b, 33b, 34b, and is the structure which incorporates one or more. These four cable portions 31, 32, 33, and 34 are arranged in a substantially strip shape, and are connected to each other and integrated as in the first embodiment. In addition, when using what has a pipe | tube as a cable part, like the said 1st Embodiment, a sheath is abbreviate | omitted and it is connected and integrated with another cable part and a sheet | seat body as a pipe | tube as a direct cable part. Also good.

  The sheet body 35 is formed of the same material as the sheaths 31b, 32b, 33b, 34b of the cable portions 31, 32, 33, 34, and the four cable portions 31, 32, 33, 34 has a width adjacent to any one of 34, and is thin enough to be easily deformed so as not to affect the bending of each cable portion, and is integrally connected to the outer periphery of the cable portions 31, 32, 33, 34. It is the structure arranged. In addition, if this sheet body has the flexibility which does not affect the bending of each cable part, and can be connected to the outer periphery of each cable part without any difficulty, it is a material different from the sheath of the cable part. It may be formed by.

  The block body 36 is formed of a material harder than the cable portions 31, 32, 33, 34 and the sheet body 35, has a width that is substantially the same as the sheet body 35, and has a rigidity that does not easily deform. It is configured to have a large height dimension and is integrally connected to the surface of the sheet body 35 and arranged in large numbers. The corner portion of the connecting surface that is integrally connected to the sheet body 35 of the block body 36 has a notch shape, and the outer peripheral surface of the cable portions 31, 32, 33, 34 that repeatedly bends and expands via the sheet body 35. Thus, a state where stress is applied from the corner of the block body 36 can be avoided.

  The cable portions 31, 32, 33, 34 are provided with a large number of the block bodies 36 arranged via the sheet body 35 so as to restrict bending, so that the cable portions 31, 32, 33, 34 is bent only in a direction in which the side where the block body 36 exists is the outside.

  A projecting portion 37 as the restraining portion is formed in a projecting projecting shape and disposed integrally with the block body 36 at one portion of the block body 36 in the longitudinal direction of the cable portion. Further, in the block body 36, a concave portion 36 a into which the convex portion 37 of another block body can be inserted is formed at the other side portion in the cable portion longitudinal direction.

  The concave portion 36a has a groove-like concave shape that does not restrain the convex portion 37 in the block body thickness direction that is perpendicular to the cable portion longitudinal direction and the cable portion side-by-side direction (block body width direction). . And the said convex part 37 is extended toward the other block body adjacent on one side of the cable part longitudinal direction from the integral block body 36, and has inserted the recessed part 36a in this other block body. The block body 36 is formed to have a sufficient length that can be maintained even after the relative movement of the block body 36 relative to the other block body accompanying the bending deformation of the cable portion. That is, the concave portion 36a is in a state where the convex portion 37 is always inserted. Moreover, in the state which extended the cable part linearly and made the block bodies 36 approach closest, the recessed part 36a will fit with the convex part 37, and the block bodies 36 will be connected.

  The convex portion 37 has a tapered shape with a width that decreases toward the distal end portion, and the concave portion 36 a also has a shape having a tapered gap corresponding to the tapered shape of the convex portion 37. Thereby, in the fitting state of the convex part 37 and the recessed part 36a, while each side part of the convex part 37 and the recessed part 36a closely_contact | adheres, the cable parts 31, 32, 33, 34 are bent, and the convex part 37 and the recessed part In the state where the fitting with 36a is released, the side portions of the convex portion 37 and the concave portion 36a are slightly separated, and the adjacent block bodies move relative to each other in accordance with the movement of the cable portion such as bending. Even in the repeated situation, it is possible to prevent the side portions of the convex portion 37 and the concave portion 36a from sliding and to prevent the side portions from being worn.

  Each block body 36 has a stepped portion in the longitudinal direction of the cable portion, with a part of the end portion on one side in the longitudinal direction of the cable portion being partially cut away from the outer periphery of the cable portion. And a second staircase having a stepped portion in the longitudinal direction of the cable portion with a portion near the outer periphery of the cable portion being partially cut out at the other end portion in the longitudinal direction of the cable portion. The portion 36c is provided.

  In the first stepped portion 36b, the stepped surface portion 36d that is closer to the outer periphery of the cable portion due to the notch is formed in the notch in the second stepped portion 36c of another adjacent block body. Accordingly, the stepped surface portion 36e that is separated from the outer periphery of the cable portion always faces each other. In the state where the cable portions 31, 32, 33, 34 are linearly extended and the block bodies 36 are brought closest to each other, the stepped surface portion 36d near the outer periphery of the cable portion, and the other block bodies This is a mechanism in which the stepped surface portion 36e away from the outer periphery of the cable portion overlaps and adheres.

  Further, a hole 38 penetrating in the longitudinal direction of the cable portion is formed in the block body 36, and a linear body 39 as a restraining portion different from the convex portion 37 is formed in the hole 38 in the longitudinal direction of the cable portion. Movably passed through.

  In this way, the linear bodies 39 are passed through all the block bodies 36, and each block body 36 is connected via the linear bodies 39, and the first stepped portion 36b of the block body 36 is adjacent to the other block bodies 36. Each block body 36 and the cable portions 31, 32, 33, 34 are always maintained in a state of facing the second stepped portion 36 c in the block body and the block bodies 36 are in a fixed restraint state. The integral connection state with the outer periphery can be strengthened to make it difficult to break. If the predetermined block body 36 and the cable portions 31, 32, 33, 34 are integrated integrally, the block body 36 and the cable portion are broken. The structure in which the block body 36 can maintain the positional relationship with the other block bodies even when the situation where the 31, 32, 33, and 34 are about to separate is reached, and does not fall off from the outer periphery of the cable portions 31, 32, 33, and 34. It is.

  The linear body 39 is an elongated flexible material that is continuous in the longitudinal direction of the cable portion and can be bent along the cable portions 31, 32, 33, 34, and is passed through the hole 38 of each block body 36, The block body 36 is combined with all the block bodies 36 while allowing the block body 36 to move relative to the linear body 39 in the longitudinal direction of the cable portion.

  By combining the linear body 39 with each block body 36 in a state of passing through the holes 38 of all the block bodies 36, the linear body 39 as a constraining portion combined with the predetermined block body 36 can be The relationship which will be in the insertion state in the hole 38 in this block body is materialized. This means that a shift other than the relative movement in the longitudinal direction of the cable portion due to the bending of the cable portion of another adjacent block body is less likely to occur with respect to the predetermined block body 36 due to the interposition of the linear body 39. To do. Thus, regardless of the bent state of the cable portions 31, 32, 33, 34, the series of block bodies 36 whose displacement is restricted by passing through the linear body 39 are connected to the cable portions 31, 32, 33, 34. This acts to prevent deformation in the lateral direction other than the direction of bending.

  Next, a use state of the movable body long body according to the present embodiment will be described. Similar to the first embodiment, the movable part elongate body 30 is disposed in a predetermined region in a state of being bent in a U shape, and has one end as a moving end and the other end as a fixed end. The position of the bent portion is changed corresponding to the movement of the moving end. At this time, even if an external force or the like tries to bend the cable portions 31, 32, 33, 34 so that the side where the block body 36 exists is inside, the block bodies 36 abut against each other in the longitudinal direction of the cable portion and move relative to each other. Without bending, the cable portions 31, 32, 33 and 34 are prevented from bending.

  On the other hand, when the cable portions 31, 32, 33, 34 corresponding to the state bent in the U-shape are bent with the side where the block body 36 exists outside (see FIGS. 8, 11). ), The block bodies 36 can move relative to each other in the longitudinal direction of the cable portion, do not become an obstacle to bending, and the cable portions 31, 32, 33, 34 can be bent. As a result, the cable portions 31, 32, 33, and 34 are bent only in the direction in which the side where the block body 36 exists is the outside. In this way, in the movement operation of the moving end of the movable part long body 30, unintended unnecessary bending does not occur in each part of the movable part long body 30, and the movement operation is performed stably.

  Further, in each block body 36, the convex portion 37 formed integrally with the block body 36 is always inserted into the concave portion 36 a drilled in the other adjacent block body, and the first in the block body 36 is set. The stepped surface portion 36d of the stepped portion 36b of the second stepped portion 36b is arranged so as to always face the stepped surface portion 36e of the second stepped portion 36c of the other adjacent block body. The body linear body 39 is combined through the hole 38 of the block body 36 and is always inserted into the hole 38 of the other adjacent block body.

  As a result, regardless of the bent state of the cable portions 31, 32, 33, 34, in addition to the restraint by the convex portion 37 and the concave portion 36 a, the presence of the linear body 39 becomes an obstacle, so that the predetermined block body 36 can be prevented. Deviations other than relative movement associated with the bending of the cable part between other adjacent block bodies, in particular, deviations in the block body width direction that coincide with the cable part juxtaposition direction are less likely to occur. In addition, at the bent portions of the cable portions 31, 32, 33, 34, the first stepped portion 36b of the block body 36 maintains the facing state with the second stepped portion 36c of another adjacent block body. Thus, the displacement of the other block body adjacent to the block body 36 other than the relative movement associated with the bending of the cable part, in particular, the radial direction with respect to the center of the bending circle of the bent part of the cable parts 31, 32, 33, 34 in the arc shape. It is possible to obtain a state in which the deviation of the cable portions 31, 32, 33, and 34 is bent evenly without distortion. Thus, based on the difficulty of shifting between the block bodies 36, the deformation in each direction other than the bending direction of the cable portions 31, 32, 33, 34 can be prevented.

  In particular, in a portion where the cable portions 31, 32, 33, and 34 are not bent as a straight line, the convex portion 37 integral with the block body 36 is in a fitted state with the concave portion 36a, and the stepped shape of the block body. The portions 36b and 36c are in close contact with each other. As a result, the block bodies 36 are integrally connected to each other and are not displaced in each direction, and the block body 36 as a whole prevents the linear portions of the cable portions 31, 32, 33, 34 from being deformed in each direction, The linear shapes of the cable portions 31, 32, 33, and 34 can be reliably maintained, and the cable portions 31, 32, which take a U-shaped bent form when moving the moving end of the movable body long body 30 are moved. About the linear part of 33 and 34, the linear shape can be maintained and the behavior of the cable parts 31, 32, 33, and 34 can be made very stable.

  Thus, in the movable body long body according to the present embodiment, one end and the other end of the block body 36 in the longitudinal direction of the cable portion are partially cut out, so that the block body 36 Stepped portions 36b and 36c are respectively formed on the side away from the outer periphery of the cable portion and on the portion closer to the outer periphery of the cable portion, and the first stepped portion 36b of the block body 36 is the second in the other block body 36 next to the other. The stepped portions 36b and 36c are in close contact with each other at a portion where the cable portions 31, 32, 33 and 34 are not bent in a straight line. Therefore, in the bent part of the cable portions 31, 32, 33, 34, the first stepped portion 36b of the block body 36 is in contact with the second stepped portion 36c of the other adjacent block body. Maintaining the orientation state, a deviation other than the relative movement associated with the bending of the cable part of the other block body adjacent to the block body 36, in particular, the bending circle of the bent part of the cable parts 31, 32, 33, 34 in the arc shape In addition to making it difficult to cause radial deviation with respect to the center and obtaining a state where the bent portions of the cable portions 31, 32, 33, and 34 are bent evenly without distortion, the cable portions 31, 32, 33, and 34 are straightened. As shown, the stepped portions 36b and 36c of the block body 36 are in close contact with each other, and the positional relationship of the block body 36 with respect to the outer periphery of the cable portion is constrained to each other, that is, adjacent to the predetermined block body 36. The vertical displacement of the other block bodies will be suppressed, and the upper and lower portions of the linear portions of the cable portions 31, 32, 33, 34 as the block body 36 as a whole. Modified to prevent the, will be a linear shape of the cable portion 31, 32, 33, and 34 can be reliably maintained, it can be further stabilized ones behavior of the cable portion 31, 32, 33 and 34.

  In addition, in the movable body long body according to each of the first to third embodiments, the cable portion is configured to have a simple circular cross-sectional shape. However, it may be configured to have another cross-sectional shape such as a polygonal shape such as a shape having a groove or a protrusion for identification.

  Moreover, in the movable body long body according to each of the first to third embodiments, the block body is formed of a material harder than the cable portion or the sheet body. It is also possible to select the material of the sheath of the cable part as appropriate so that the block body has the same hardness as that of the cable part and the sheet body. Thus, the block body can be set to an appropriate hardness.

(Fourth embodiment of the present invention)

However, the present invention is not limited to this, and the movable body long body 40 according to the fourth embodiment may include a plurality of core wires and / or tubes as shown in FIG. It is also possible to employ a configuration in which a single flat belt-like cable portion 41 having flexibility is used, and a plurality of block bodies 42 are arranged side by side in the longitudinal direction of the cable portion 41 on a part of the outer periphery of the cable portion 41. .

  Specifically, the cable portion 41 is formed in a flat strip shape having a predetermined thickness dimension, and is an elongated material for operation for passing an operating element, that is, a core wire 41a for passing electricity and light as an operating element, 41b, 41c and / or a pipe 41d through which air or hydraulic oil as an operating element passes is covered with a sheath 41e, and a plurality of pipes 41d are built in. Each core wire and / or pipe is divided and arranged in parallel in the cable portion width direction for each type and function.

  Since the flat belt-like cable part 41 and the block body 42 can secure a sufficient contact area, even if the cable part 41 and the block body 42 are made of different materials, this is ensured in a state where they are integrated by bonding or the like. An integrated state can be maintained, and the block body 42 does not separate from the cable portion 41 due to stress caused by repeated bending due to movement, and the block body 42 has a function of limiting the direction of bending until the life of the cable portion 41 is reached. Can be maintained.

  In addition to the case where the flat belt-like cable portion 41 is employed in this way, each cable portion shown in each of the embodiments includes a linear body other than a long working material such as a core wire or a tube, for example, a cable. A tension member that strengthens and adjusts the rigidity and elasticity of the part can also be provided, and the bending direction is restricted together with the block body, causing an unintended unnecessary bending in the long body for the movable part. In addition, the bending portion can be set to a desired curvature by adjusting the rigidity of the cable portion.
