[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of link bodies, which are formed by connecting a pair of oppositely arranged link plates having an upper edge portion and a lower edge portion with a connecting member, so as to be bendable.
The present invention relates to a protective guide chain for a cable hose capable of accommodating and guiding hoses such as a power cable, a hydraulic hose, and an air hose inside.

[0002]

2. Description of the Related Art Conventionally, assembling type cable hose protection guide chains have two side plates (hereinafter referred to as "link plates") spaced apart and opposed to each other and partially different in shape from each other and the upper edge portions of the link plates. A rectangular link body has been formed by four types of components, that is, a flap to be coupled and a bottom plate that couples lower edge portions, or three types of components in which the flap and the bottom plate are commonly used in the same shape. A guide chain is formed by fitting these link bodies so that the link plates partially overlap each other and rotatably connecting them within a predetermined range.

An example of the protection guide chain for the cable hose will be described with reference to JP-A-5-141481. This guide chain (cable drag chain)
A plurality of link bodies, in which a pair of link plates facing each other apart from each other are coupled by a coupling rod, are flexibly coupled by fitting a shaft and a fitting hole formed in a portion where the link plates overlap each other. Specifically, inward stoppers are formed at equal intervals around a shaft formed in a circular recess formed on the inner surface of the link plate. In addition, the circular convex portion formed on the outer surface of the link plate,
A fitting hole into which the shaft can be fitted is formed, and a pair of stopper receiving portions capable of receiving the inward stopper and outward stoppers formed on both sides thereof are equidistantly provided around the fitting hole. . Then, when the link plates rotate, the inward stopper and the outward stopper contact each other to regulate the rotation angle of the link plate and receive the regulation force, and the rotation angle between the shaft and the fitting hole. The power to regulate is not added.

[0004]

However, the cable hose protection guide chain represented by Japanese Patent Laid-Open No. 5-141481 has the following problems. The link plates that face each other and form the link body are rotatably connected to each other at a coupling portion. The coupling part is provided with inward and outward stoppers for restricting the rotation range, but in order to rotate the left and right link plates in the same direction, the arrangement shape of the opposing stoppers is left and right. Since it is necessary to be symmetrical on both sides, two types of link plates with different arrangements of stoppers at the coupling portions corresponding to the left and right link plates are required. Also, since the inward and outward stoppers are integrally formed on the link plate, when a link body with a different rotation range is required, a new link plate with a different stopper arrangement shape is required as a separate component. ,
The number of parts increases.

Further, since the shape of the link plate is different between the left and the right, a mold for resin molding is additionally required, resulting in a significant increase in manufacturing cost, and also inconvenient inventory management due to the large number of parts. was there. Further, the connecting rod that connects the link plates arranged opposite to each other is formed so as to be openable and closable so that the hoses can be easily taken in and out. However, because the linking strength of the link body is reduced, etc., only one side of the connecting rod can be attached and detached so that it can be opened and closed.Therefore, the mounting direction of the guide chain to the mounting machine is limited, and the device layout is also limited. There was also the problem that it would be done.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a protective guide chain for a cable hose that minimizes the number of parts to reduce the manufacturing cost and is easy to handle. .

[0007]

In order to solve the above problems, the present invention has the following constitution. That is, a cable hose capable of accommodating a hose or the like by linking a plurality of link bodies that are bendable by connecting a pair of upper and lower edge portions of a pair of link plates facing each other apart from each other with a coupling member.

First, the structure of a link body, which is a unit of a protective guide chain for a cable hose (hereinafter simply referred to as "guide chain"), will be described with reference to FIG. In this embodiment, a so-called O-type guide chain in which the flap and the bottom plate are formed as separate members will be mainly described. The O type guide chain is housed so that the hoses housed in the inner space cannot be seen from the outside. Reference numeral 1 denotes a link body, which is a pair of link plates 2 having the same shape and facing each other.
Is used. The upper edge portion 3 and the lower edge portion 4 of the pair of link plates 2 are connected by a flap 5 and a bottom plate 6 used as a connecting member. Link body 1
Are continuously provided in the longitudinal direction so that the inner and outer surfaces of the link plate 2 are superposed on each other. A guide chain formed by connecting a plurality of link bodies 1 so as to be bendable is attached so as to connect a device body such as an installation machine and a moving body, and has a power cable, a hydraulic hose, and Guide by accommodating hoses such as air hoses.

A link plate 2 forming the link body 1,
The flap 5, the bottom plate 6 and the turning angle restricting piece 8 described later are made of resin by injection molding or the like, and have sufficient rigidity as a guide chain and are smooth without damaging the hoses housed in the internal space. It must be a resin molded product having a smooth surface. In this embodiment, for example, a resin material in which a glass fiber filler is mixed as a reinforcing filler into a composite material of aliphatic polyamide and aromatic polyamide is preferably used. In this case, since the reinforcing filler is embedded in the resin material and resin-molded, the filler does not protrude from the surface of the resin molded product, and the surface can be molded into a smooth glossy surface. Therefore, it is possible to prevent the hoses housed in the guide chain from rubbing against the resin material and damaging the hoses. The filler is not limited to the glass fiber filler, and other reinforcing filler such as mineral fiber filler can be used. Further, the filler may have various shapes such as a needle shape, a square shape, or a spherical shape.

Both the aliphatic polyamide resin and the aromatic polyamide resin are crystalline polymers, have compatibility with each other, and have the characteristic that they do not eutectic near the melting point. Aromatic polyamide resin has an action of delaying crystallization as compared with the case of resin molding using only an aliphatic polyamide resin, and even when the aliphatic polyamide resin is crystallized and contracts, it is crystallized with almost no contraction, It has the function of sufficiently transmitting the injection pressure during molding. In this way, by using the composite material of the aliphatic polyamide resin and the aromatic polyamide resin, the resin filling property up to the mold surface is good, and the mold transferability is good if the mold surface is mirror-finished. It is possible to make the surface of the resin molded product a flat surface without unevenness.

Next, the structure of each part of the link body 1 will be described in more detail. 1 and 2, the link plate 2 is provided with a rotation stopper claw 7 and a rotation angle regulation piece 8 that can be fitted in another link plate 2 in an overlapping manner. Specifically, the outer surface 9 of the link plate 2
The connecting portion 10 having a relatively thin plate is formed on the
The connecting portion 10 has a circular outer boss portion 11 (first boss portion).
Are formed. Rotation stopper claws 7 are formed on the inner wall of the outer boss portion 11 at equiangular distribution positions in the circumferential direction of the outer boss portion 11 (positions facing each other by 180 ° in this embodiment).

On the inner side surface 12 of the link plate 2, there is formed a connecting portion 13 having a relatively thin plate thickness, and the connecting portion 13 has a circular inner boss portion 14 (second boss portion). Has been formed. At the center of the inner boss portion 14, the shaft 15
Is provided in a protruding manner, and a mounting claw 16 is provided around the shaft 15.
They are provided facing each other by 80 °. Shaft 15 and mounting claw 16
The rotation angle regulation piece 8 is fitted in the. The outer boss portion 11 is fitted inside the inner boss portion 14 to connect the connecting portion 10 of the link plate 2 and the other link plate 2 to each other.
And the connecting portion 13 of are rotatably fitted. At this time, the rotation stopper claw 7 is fitted into the rotation area allowed by the rotation angle regulation piece 8, and the rotation stopper claw 7 abuts on both side abutting portions 8 a of the rotation angle regulation piece 8. The rotation range of the link plate 2 is restricted. Outer boss 1
1 and around the inner boss portion 14, fitting portions 11a and 14a capable of fitting concave and convex with a fitting hole formed in a mounting bracket described later.
Are formed respectively.

Further, one link plate 2 of each link body 1 is arranged upright, and the other link plate 2 is arranged upside down by being inverted by 180 ° about a center line P in the longitudinal direction. That is, the pair of link plates 2 constituting the link body 1 are arranged so that the connecting portions 13 of the inner side surface 12 face each other and the connecting portions 10 of the outer side surface 9 face each other, The plates 2 are connected to each other on both sides in the longitudinal direction. In the present example, a mark 2a serving as an index indicating whether it is upright or inverted is provided on the outer surface 9 of the link plate 2 for the sake of explanation. FIG. 2A shows a right side plate of the link body 1 of FIG. 1 and shows an outer side surface 9 of the right side plate. FIG. 2B shows the link plate 2 shown in FIG. 2A in the vertical direction about the center line P in the longitudinal direction.
It shows a state of being inverted by 80 °, and shows the inner side surface 12 of the left side plate of the link body 1 of FIG. 1. Figure 2
2C shows a state in which the link plate 2 shown in FIG. 2B is inverted by 180 ° about the orthogonal line Q,
It shows the outer surface 9 of the left side plate of the link body 1 of FIG. 2 (d) shows a state in which the link plate 2 shown in FIG. 2 (c) is vertically inverted by 180 ° about the longitudinal centerline P, and the right side plate of the link body 1 of FIG. It shows the inner surface 12 of the.

In this embodiment, as shown in FIG.
The rotation stopper claw 7 and the mounting claw 16 formed on the connecting portion 10 and the connecting portion 13 of the link plate 2 respectively include the shaft 15
Is provided at a position facing each other by 180 ° on the vertical line Q and the horizontal center line P centered at
It is not limited to this. At least the rotation stopper claw 7 may be formed at a position where it is equiangularly distributed in the circumferential direction on the inner wall of the outer boss portion 11 formed on the outer surface 9 of the link plate 2. In addition, the mounting claw 16 has the inner boss portion 14
It suffices that the rotation stopper claws 7 of the outer boss portion 11 of the other link plate 2 are fitted in and are formed at positions where the rotation areas are partitioned equiangularly.

As shown in FIG. 3B, the rotation stopper claw 7 and the mounting claw 16 are formed at positions which are swung by a predetermined angle with respect to the center line P and the orthogonal line Q about the shaft 15. Is also good. Further, the rotation stopper claw 7 and the mounting claw 16 are 2
It is not limited to the case of forming each place, but may be formed at three places (see FIG. 3C) or may be formed at one place (see FIG. 3D). In any case, it is necessary that the turning stopper claw 7 and the turning angle regulating piece 8 can be fitted into each other, and that the turning directions of the left and right link plates 2 are aligned with each other.

Also, the mounting claws 1 of the left and right link plates 2
As the rotation angle regulation piece 8 fitted in 6, the rotation angle regulation piece 8 having the same shape is used. In this case, the rotation angle regulation piece 8 fitted on the inner side surface 12 of the link plate 2 arranged upside down
Need to be adjusted because the upright arrangement of the link plate 2, the claw position, the bridge position, and the turning direction may not correspond to each other. Therefore, in FIGS. 3A to 3D, it is assumed that the link plate 2 on the left side is arranged upright and the rotation angle regulating piece 8 fitted in the mounting claw 16 is used as a reference, and the link plate 2 is arranged upside down. The rotation angle restricting piece 8 fitted in the right side link plate 2 is 180 degrees up and down with the link plate 2 with respect to the upright side about the longitudinal centerline P.
The inverted one is horizontally inserted 180 ° in the horizontal direction with the orthogonal line Q orthogonal to the center line P as the axis of symmetry and fitted into the mounting claw 16. As a result, the rotation direction and the rotation range of the rotation stopper claw 7 regulated by the left and right rotation angle regulating pieces 8 are the same on the left and right sides, so that the rotation angle regulating pieces 8 of the same shape are arranged on the left and right sides. Can be used in. By using the rotation angle regulation pieces 8 having different rotation angle regulation ranges for each link body 1, the bending angles of the link bodies 1 can be variously adjusted.

As described above, since the link plate 2 and the turning angle regulating piece 8 having the same shape on the left and right can be used in reverse,
The manufacturing cost can be reduced by omitting the number of parts. In particular, since it is not necessary to manufacture the left and right link plates 2 by resin molding with different molds, the manufacturing cost can be significantly reduced. Further, the troublesomeness of inventory management can be eliminated, and errors in the assembly work such as connecting the left and right link plates 2 by mistake can be reduced, so that the handleability is improved.

Further, in FIG. 4, separation preventing hooks 17 are formed near the connecting portion 10 on the outer side surface 9 and the connecting portion 13 on the inner side surface 12 of the link plate 2, respectively. As described above, since the link body 1 is a resin molded product, it rotates when the link plate 2 is connected to another link plate 2, and the rotation stopper formed on the connecting portion 10 of the outer side surface 9. Due to the stress strain applied when the claw 7 hits the abutting portion 8a of the rotation angle regulating piece 8 fitted in the connecting portion 13 of the inner side surface 12, the connecting portions 10 and 13 are deformed inward or outward so that there is an escape. easy. This link plate 2
In order to prevent the connecting portions 10 and 13 from escaping, separation preventing hooks 17 are formed near the connecting portions 10 and 13, respectively.

As shown in FIGS. 2B and 2D, the inner surface 12 of the link plate 2 is formed with a plurality of fitting holes 12a in the vertical direction. The other end of the shelf plate, one end of which is supported by a partition plate described later, can be fitted into the fitting hole 12a.

In FIG. 5A, the flap 5 is rotatably attached to the upper edge 3 of the link plate 2. Rotation locking portions 5a and fixing locking portions 5b (see FIG. 6B)) are formed on both sides of the flap 5 in the longitudinal direction. A slit 5c for releasing the fixing is formed above the fixing locking portion 5b. Further, on the lower surface of the flap 5, a mounting groove 5d and a holding groove 5e are formed in the longitudinal direction so that a partition plate described later can be erected in the longitudinal direction (see FIG. 9).

Further, in FIG. 6A, an opening / closing holding portion 18 and a fixing holding portion 19 are formed on the upper edge portion 3 of the link plate 2, respectively. In FIG. 6B, the rotation locking portion 5 a of the flap 5 is rotatably locked to the opening / closing holding portion 18 of the upper edge portion 3, and the fixing locking portion 5 b is fixed to the fixing holding portion 19. It is locked and fixed to. Flap 5
By releasing the fixing of the fixing locking portions 5b on both sides with the fixing holding portion 19 and releasing the locking of the one rotation locking portion 5a with the opening / closing holding portion 18, they are respectively attached and detached from both end sides. And it can be opened and closed.

In FIG. 5B, the bottom plate 6 is rotatably attached to the lower edge 4 of the link plate 2. Rotational locking portions 6a and fixing locking portions 6b are formed on both sides of the bottom plate 6 in the longitudinal direction. A slit 6c for releasing the fixing is formed below the fixing locking portion 6b (see FIG. 6B). Further, on the upper surface of the bottom plate 6, a mounting groove 6d and a holding groove 6e are formed in the longitudinal direction so that a partition plate described later can be erected in the longitudinal direction.

Further, in FIG. 6A, an opening / closing holding portion 18 and a fixing holding portion 19 are also formed on the lower edge portion 4 of the link plate 2. In FIG. 6B, the rotation locking portion 6 a of the bottom plate 6 is the opening / closing holding portion 18 of the lower edge portion 4.
The locking portion 6b for locking is locked and fixed to the holding portion 19 for fixing. The bottom plate 6 releases the fixing of the fixing locking portions 6b on both sides with the fixing holding portion 19,
By releasing the locking of the one rotation locking portion 6a with the opening / closing holding portion 18, it is possible to attach / detach and open / close from both ends. As described above, the flap 5 and the bottom plate 6 are provided with the double locking portions for turning and fixing, respectively, when the link body 1 is opened and closed when the flap 1 or the bottom plate 6 is opened and closed. This is to maintain the strength so that the shape of can be maintained.

The opening / closing operation of the flap 5 and the bottom plate 6 will now be described with reference to FIGS. In FIG. 7, the minus driver 20 is inserted into the insertion opening 21 formed in the upper edge portion 3 of the one link plate 2 in the direction of the arrow F1, and the fixing locking portion 5 on one side of the flap 5 is inserted.
The fixing of b and the holding portion for fixing 19 is released. In addition, with the driver 20 still inserted into the insertion port 21, the arrow F
By pushing up in two directions, the rotation locking portion 5a can be released from the opening / closing holding portion 18 and one side can be freed.
Further, as shown in FIG. 8, when the minus driver 20 is pushed into the slit 5c on the other side of the flap 5 in the arrow F3 direction and tilted in the arrow F4 direction, the link plate 2
The fixing between the fixing locking portion 5b and the fixing holding portion 19 is released. Then, as shown in FIG. 9, the opening / closing holding portion 18 with which the rotation locking portion 5a on one side locks the flap 5 on which the rotation locking portion 5a on one side is free is rotated. The upper portion of the link body 1 can be opened by rotating the bottom plate 6 to a position vertically above. When the flap 5 is removed from the link plate 2, the operation of inserting the driver 20 shown in FIG. 7 by inserting the insertion port 21 may be performed on both ends of the flap 5. As with the flap 5, the bottom plate 6 can also be opened by using a minus driver 20 as shown in FIG.

In this way, the upper edge portion 3 of the link plate 2 is
By allowing the flap 5 and the bottom plate 6 for connecting the space and the lower edge portion 4 to be opened and closed by freeing one end side, it is easy to take out the hoses with the link body 1 connected, which is convenient. . Further, since the flap 5 and the bottom plate 6 can be opened and closed from both ends, there is no restriction on the layout of the installation machine or the like, so that the degree of freedom in design is expanded.

Next, a partition plate for partitioning the internal space of the link body 1 will be described with reference to FIGS. 11 to 16. Hoses are housed in the internal space of the link body 1. However, if the internal space is large with respect to the hoses, when the link body 1 is repeatedly moved together with a moving body equipped in an installation machine (not shown), the hose is Problems such as twisting or hose entanglement may occur. There are also cases where the user wants to partition the internal space for each hose of the same type for wiring in consideration of design convenience and maintenance. For this reason, the partition plate is preferably used in order to safely guide the hoses housed in the internal space and to use them efficiently.

In FIG. 11, a partition plate 22 partitions the internal space of the link body 1 in the left-right direction. At the upper and lower ends of the partition plate 22, mounting grooves 5d, 6d and holding grooves 5e, 6 formed in the longitudinal direction of the flap 5 and the bottom plate 6 are formed.
A mounting block 23 and a holding hook 24 that can be fitted in each e are formed. The mounting block 23a and the locking projection 23b (see FIG. 12) are fitted into the uneven portions formed at a plurality of positions in the longitudinal direction of the mounting grooves 5d and 6d. The holding hook 24 is formed by providing slits at the upper end and the lower end in the longitudinal direction of the partition plate 22, respectively, and elastically deforms when entering the holding grooves 5e, 6e, and the mounting grooves 5d, 6d and the holding grooves. 5e, 6e
It is installed so as to sandwich the part partitioned by. When the flap 5 or the bottom plate 6 is opened from the link body 1, the holding hook 24 has one of the upper and lower holding grooves 5e,
The partition plate 22 is prevented from coming off from the link body 1 by entering and pinching it in 6e. The partition plate 22 is
The attachment block 23a and the locking projection 23b are flaps 5
Also, by fitting it into the mounting grooves 5d, 6d at any position of the bottom plate 6 and engaging the holding hooks 24 with the holding grooves 5e, 6e, they are attached to the link body 1 and partition the internal space into left and right. .

FIG. 12 shows another partition plate 25. The partition plate 25 is for not only partitioning the internal space of the link body 1 into left and right but also partitioning into upper and lower parts. If only the left and right partition plates 22 form a large space with respect to the hoses, or if you want to prevent entanglement by partitioning and wiring the inner space for each hose, make the inner space smaller. It is convenient that it is partitioned. Specifically, a support member 27 formed by being partitioned by a plurality of slits 26 in a direction perpendicular to the longitudinal direction of the partition plate 25 can be supported by engaging one end of a shelf plate 28 shown in FIG. The engaging portion 27a is formed. This shelf 28
The other end of is fitted into a fitting hole 12a formed in the inner side surface 12 of the link plate 2. It is possible to vertically partition the internal space partitioned by the partition plate 25 into the left and right by the shelf plate 28. Similar to the partition plate 22, the partition plates 25 have mounting grooves 5d, 6d and holding grooves 5e, which are formed in the longitudinal direction of the flap 5 and the bottom plate 6, at the upper and lower ends.
A mounting block 23a, a locking projection 23b, and a holding hook 24, which can be fitted in 6e, respectively, are formed.

Further, since the partition plate 25 partitions the internal space of the link body 1 into right and left, it is erected at arbitrary positions in the longitudinal direction of the flap 5 and the bottom plate 6, so that the length of the shelf plate 28 in the longitudinal direction is increased. Also, the number of lengths corresponding to the mounting position of the partition plate 25 is required. Considering the case where the shelf boards 28 are provided in multiple stages at the top and bottom, a plurality of types of shelf boards 28 having different lengths
Since it is necessary to prepare a large number of molds, and a mold for an injection molding machine is also required according to the type of the shelf plate 28, the manufacturing cost significantly increases as the number of parts increases, and inventory management becomes troublesome. On the other hand, in this embodiment, the shelf board 2
Reference numeral 8 is formed so as to be expandable and contractable in the longitudinal direction according to the mounting position of the partition plate 25. As a result, it is possible to summarize the possible length range of the shelf boards of all length sizes according to the mounting position of the partition plate 25, omit the number of parts, and deal with the minimum necessary number of parts. It was done.

Here, the structure of the shelf board 28 will be described with reference to FIGS.
This will be described in detail with reference to FIG. In FIG. 14A, the shelf board 28 has a main body plate 29 and a drawer plate 30. In FIG. 14B, the drawer plate 30 is fitted in the body plate 29 so as to be drawn out while being guided by the slide guides 31 formed in the L shape on both sides. Body plate 2
An engaging end portion 29a that can be engaged with the engaging portion 27a of the support member 27 of the partition plate 25 is formed at the rear end portion of 9 in the drawing direction. In addition, a fitting protrusion 30a that is fitted into a fitting hole 12a formed in the inner side surface 12 of the link plate 2 is formed at the front end of the drawer plate 30 in the drawing direction.

15 (a) to 15 (d), saw-toothed locking teeth 32 are formed in the longitudinal direction on the bottom of the main body plate 29. 16 (a) to (d),
Locking claws 33 that can mesh with the locking teeth 32 are formed on the drawer plate 30. This locking tooth 32 and locking claw 3
When the pull-out plate 30 is pulled out, the shape of No. 3 moves so that the locking claw 33 moves over the inclined surface of the locking teeth 32 and meshes at an arbitrary position. When the pulled-out pull-out plate 30 is stored again in the main body plate 29, the gap 34 formed around the locking claw 33 is formed.
Insert a flat-blade screwdriver or the like into the drawer plate 30 with the engagement of the engagement claw 33 and the engagement tooth 32 released.
Should be stored along the slide guide 31 of the body plate 29.

The shelf board 28 can be supplemented by one shelf board 28 from the length of the main body plate 29 to the length range in which the drawer plate 30 is pulled out from the main body plate 29 to the maximum extent. Therefore, since it is sufficient to prepare, for example, about four kinds of shelf boards 28 having different lengths, it is possible to significantly reduce the number of parts and reduce the manufacturing cost, and it is troublesome to manage the inventory of many kinds of shelf boards having different lengths. It is also possible to improve usability without being lost.

FIG. 17 shows a state in which the guide chains 35 are assembled by connecting the link bodies 1 to each other. Guide chain 3
5 is formed by horizontally inverting the same link plate 2 and sequentially connecting them in the same direction in the longitudinal direction. Also,
The guide chain 35 is configured such that, in the arbitrary link body 1, the flap 5 and the bottom plate 6 are released from the upper and lower sides by releasing the fixation to the link plates 2 at both end sides. If necessary, partition plates 22, partition plates 25, and shelf plates 28 are provided in the mounting grooves 5d, 6d and the holding grooves 5e, 6e formed in the flap 5 and the bottom plate 6 to safely guide the hoses. Therefore, it is possible to effectively use the internal space.

At both ends of the guide chain 35, fixed side mounting brackets 36 and moving side mounting brackets 37 for mounting on the apparatus main body of the installation machine and the moving body are mounted (see FIG. 17). In FIG. 18A, the fitting hole 36 a formed in the fixed side mounting fitting 36 is the link plate 2
Fitting portion 14a of the inner boss portion 14 formed on the inner side surface 12 of the
Is fitted into. In FIG. 18 (b), the fitting hole 37 a formed in the moving side mounting member 37 is the fitting portion 11 of the outer boss portion 11 formed in the outer surface 9 of the link plate 2.
It is fitted in a. The fixed-side mounting bracket 35 and the moving-side mounting bracket 36 are respectively formed with screw stoppers 36b and 37b that are fixed to the apparatus body of the installation machine and the moving body (see FIG. 17).

Since the link plate has a hole formed in the conventional fixed-side mounting member, a pin for fitting in the hole is provided. However, since this pin is formed, it is difficult to adopt various mounting methods for the fixed side mounting bracket to the link plate with the same component. In this embodiment, since the fixed-side and movable-side mounting fittings are fitted by fitting with the boss portion, various mounting methods can be adopted. For example, the fixed side mounting bracket 36 will be described.
Is a lower screw stopper, and the screw stoppers 36b are on the outer sides of the link plate 2, and the screw stoppers 36b are on the inner side of the link plate 2, the screw stoppers 36b.
There are four mounting methods when one is outside and the other is inside. Further, there are also four mounting methods in which the fixed side mounting member 36 is turned upside down and the upper side screws are fixed, and a total of eight mounting methods can be realized. Similarly, since there are eight mounting methods for the moving side mounting bracket 37, a total of 16 mounting methods can be adopted.

Therefore, since various mounting methods of the fixed side mounting bracket 36 and the moving side mounting bracket 37 for mounting both ends of the guide chain 35 to the apparatus main body of the installation machine and the moving body respectively, there are few restrictions on the apparatus layout. Becomes
Greater freedom of design.

In the above embodiment, the O-type link body 1 has been described. However, as shown in FIG. 19, the same applies to the U-type link body 38 in which the flaps 5 and the bottom plate 6 have the same shape. Can be adopted. The flap 39 has the same configuration as that of the flap 5, although the outer shape of the flap 39 is different. In this U-type link body 38, a gap is formed between the flaps 39 when the link bodies 38 are connected to each other, so that the hoses accommodated in the link body 38 can be confirmed. Since the link body 38 can use the left and right link plates 2 and the upper and lower flaps 38 having the same shape as compared with the O-type link body 1,
The number of parts is even smaller and the manufacturing cost can be reduced.
There are few errors in assembly work, and inventory management is easy.

Next, another example of the link plate 2 will be described. As shown in FIGS. 20 (a) and 20 (b), shaft holes 40 are formed in the outer surface 9 of the left and right link plates 2 corresponding to the inner boss portions 14, and the rotation stopper claws of the outer boss portions 11 are formed.

Further, as shown in FIGS. 21 (a) and 21 (b), the turning angle regulating piece 8 has a fitting shaft 42 projecting in the thickness direction at the center of rotation, and a fitting claw 16 is fitted around the fitting shaft 42. Fitting holes 43 for inserting are formed in two places. The shaft ends 42a and 42b of the fitting shaft 42 are shown in FIG.
As shown in (c), the rotation angle regulation range of the rotation angle regulation piece 8 (for example, 150 °) is shown. When the rotation angle restricting piece 8 is attached to the mounting claw 16 of the inner boss portion 14, one shaft end 42a of the fitting shaft 42 is fitted into the shaft hole 40, and the rotation angle restricting piece 8 of the outer surface 9 is inserted. The rotation angle regulation range is visible. Further, when the outer boss portion 11 of the other link plate 2 is fitted into the inner boss portion 14, the other shaft end 42b of the fitting shaft 42 is housed in the counterbore hole 41. In this way, the rotation angle regulation range of the rotation angle regulation piece 8 that cannot be confirmed from the outside after assembly is
Since the link plates 2 can be visually recognized from the shaft hole 40 without releasing the connection one by one, it is easy to change to another rotation angle regulation piece 8 having a different rotation angle regulation range, and workability at the time of component replacement is improved. Good and easy to use.

According to the above structure, the link plates 2 having the same shape are used as the pair of link plates 2 forming the link body 1, one of the link plates 2 is arranged upright, and the other of the link plates 2 is in the longitudinal direction. Since it is inverted upside down by 180 ° about the center line of (1), the number of parts can be omitted and the manufacturing cost can be reduced. In particular, since it is not necessary to manufacture the left and right link plates 2 by resin molding with different molds, the manufacturing cost can be significantly reduced. In addition, the complexity of inventory management due to the large number of parts can be eliminated, and the left and right link plates 2
It is possible to reduce errors in the assembly work such as erroneous connection of the parts, so that the operability is improved. Further, the rotation angle regulating pieces 8 for regulating the rotation range of the rotation stopper claw 7 are also of the same shape on the left and right, and the inverted side is horizontally inverted 180 ° with respect to the upright side. Since the turning direction and the turning range of the turning stopper claw 7 can be made to coincide with each other on the left and right, if there is a minimum necessary turning angle restricting piece 8 for restricting the turning range, the link bodies 1 are bent. Various angles can be changed. In addition, the inner surface 12 and the outer surface 9 of the link plate 2
In this case, since separation preventing hooks 17 are formed so as to lock the side surfaces so as not to separate from each other when they are overlapped with another link plate 2, when the rotation stopper claw 7 hits the rotation angle regulating piece 8. The stress strain on

It is needless to say that many more modifications can be made without departing from the spirit of the invention, for example, the shape of the rotation angle restricting piece 8 can be variously changed.

[0046]

As described above, in the protective guide chain for the cable hose according to the present invention, the link plates having the same shape are used as the pair of link plates forming the link body, and one of the link plates is arranged upright. Since the other link plate is inverted upside down by 180 ° about the center line in the longitudinal direction, the link plate is inverted so that the number of parts can be omitted and the manufacturing cost can be reduced. In particular,
Since it is not necessary to manufacture the left and right link plates by resin molding with different molds, the manufacturing cost can be significantly reduced. In addition, the complexity of inventory management due to the large number of parts can be eliminated, and errors in assembly work such as erroneous connection of the left and right link plates can be reduced, thus improving the handleability. Further, the rotation angle regulating pieces for regulating the rotation range of the rotation stopper claws also have the same shape on the left and right sides, and the inverted side is inverted by 180 ° in the horizontal direction with respect to the upright side. Since the rotation direction and rotation range of the rotation stopper claw can be made to match on the left and right, the bending angles of the link bodies can be changed variously if there is a minimum necessary rotation angle regulation piece that regulates the rotation range. Becomes Further, since the separation preventing hooks are formed on the side surfaces of the link plates so as to prevent the side surfaces from being separated from each other when the side surfaces of the other link plates are overlapped with each other, the rotation stopper claw serves as the rotation angle regulating piece. It is possible to effectively prevent escape of the overlapped side surfaces to the inside or the outside of the link body due to the stress strain received when they abut. Also, by making it possible to remove and open and close the connecting member that connects the upper and lower edges of the link plate with one end side free, it is easy to take out the hoses from the guide chain and it is easy to use. Since there are no restrictions on the layout of equipment such as installation machines, the degree of freedom in design is expanded.
