Description

The present invention relates to a cable guiding device for guiding heavy cables, such as power cables.

The applicant has obtained a patent for a cable holding device (Patent Document 1).

The cable retainer includes a left portion and a right portion that provide a pair of inclined surfaces facing each other so that the separation distance on the lower side is small, a back portion to which the left portion and the right portion are fixed, and the A pair of moving bodies disposed facing each other so as to be movable on a pair of inclined surfaces, and a pair of elastic bodies disposed facing each other on the facing surfaces of the pair of moving bodies, wherein the pair of moving bodies , wherein the cable holding device is connected via a synchronous link so as to be movable on the pair of inclined surfaces simultaneously in the same direction at the same speed.

According to the cable holding device, the cable can be reliably held by the pair of elastic bodies arranged opposite to each other on the opposing surfaces of the pair of moving bodies that can move on the pair of inclined surfaces. In particular, the synchronous link allows the pair of elastic bodies that hold the cable to move simultaneously in the same direction at the same speed, so that the cable fall prevention function can be performed more stably.

When the cable held by the cable holding device is cut at a position above the cable holding device due to an accident or the like, the cable tends to drop due to gravity. Due to the frictional force acting between the gripped elastic bodies and the cable, the pair of elastic bodies tend to fall together with the cable. In response to this action, the pair of moving bodies holding the pair of elastic bodies tend to move downward on the pair of inclined surfaces. This moving action acts to narrow the gap between the pair of elastic bodies, and as a result, the force with which the pair of elastic bodies hold the cable increases instantaneously, effectively preventing the cable from falling.

The cable holding force for this drop prevention is greatly affected by the gripping state of the cable before it is dropped (for example, the distance between the opposing surfaces of the elastic body, that is, the distance between the contact surfaces of the elastic body and the cable). There is no Therefore, regardless of the thickness of the cable, it is possible to guarantee a sufficient cable holding force for drop prevention, and as a result, it is possible to handle a wide range of cable thicknesses (upper limit of cable thickness). is defined by the separation distance between a pair of inclined planes).

Patent No. 6762567

The above-described cable holding device is assumed to be used in the work of placing a cable drum on the lower floor and pulling up the cable from the upper floor with a winch or the like. Specifically, the above-described cable holding device is suspended near the cable extending in the vertical direction (vertical direction), and positioned so that the cable is arranged between the pair of elastic bodies. adjusted and used.

Recently, however, there has been an increase in the work of placing cable drums on the upper floors and dropping cables on the lower floors. In such a case, if the cable extending in the vertical direction is held by the above-mentioned cable holding device, the gap between the pair of elastic bodies will narrow when the cable moves in the direction of dropping the cable. Therefore, the cable cannot be dropped smoothly.

When the cable drum is placed on the upper floor and the cable is dropped on the lower floor, the inventor of the present invention stops holding the cable extending in the vertical direction (vertical direction) by the above-mentioned cable holding device and uses a pair of elastic It became necessary to stop the cable dropping operation by only guiding the cable in a state in which the distance between the bodies was widened (in a state in which the locking member was locked to the locked portion to maintain the state). We have been working on the development of a device that can hold the cable immediately.

The present invention was invented under the above background. An object of the present invention is to place a cable drum on an upper floor and smoothly guide the cable in the work of dropping the cable into the lower floor, while at the same time immediately removing the cable when it becomes necessary to interrupt the cable dropping work. It is to provide a device that can be held.

The present invention comprises a pair of left and right portions providing a pair of slanted surfaces facing each other so that the separation distance on the lower side is small, a back portion to which the left and right portions are fixed, and the pair of A pair of moving bodies disposed facing each other so as to be movable on an inclined surface, and a pair of elastic bodies disposed facing each other on the facing surfaces of the pair of moving bodies, wherein the pair of moving bodies It is connected via a synchronous link so that it can move on the pair of inclined surfaces at the same time in the same direction at the same speed. A locking member is provided, and a locked portion to which the locking member can be locked is provided on an upper portion of at least one of the left portion and the right portion, and the locking member It further comprises an unlocking mechanism capable of immediately releasing the locked state of the locking member with respect to the locked portion at a desired timing in a state where the locking member is locked to the locked portion. It is a cable guiding device.

According to the present invention, in the operation of placing the cable drum on the upper floor and dropping the cable on the lower floor, the cable guiding device is used in a state where the locking member is locked to the locked portion. On the other hand, when it becomes necessary to interrupt the cable dropping operation, the locking release mechanism can immediately release the locked state of the locking member from the locked portion, and the pair of A pair of movable bodies each movable on an inclined surface can move downward by gravity, and a pair of elastic bodies arranged opposite to each other on the opposing surfaces of the pair of movable bodies immediately and reliably grip the cable. can do.

Once the pair of elastic bodies grip the cable, the pair of elastic bodies gripping the cable also tries to fall together with the cable as the cable is dropped. In response to this action, the pair of moving bodies holding the pair of elastic bodies tend to move further downward on the pair of inclined surfaces. This moving action further narrows the gap between the pair of elastic bodies, resulting in an instantaneous increase in the force with which the pair of elastic bodies hold the cable, effectively preventing the cable from further dropping. be done.

The cable retention force for this further drop prevention is not greatly affected by the thickness of the cable. Therefore, regardless of the thickness of the cable, it is possible to guarantee a sufficient cable holding force for further prevention of dropping, and as a result, it is possible to correspond to a wide range of cable thicknesses (cable thickness is defined by the distance between the pair of inclined planes).

In the present invention, the locking member rotates via a rotating pin, and has a hook portion. and the unlocking mechanism pushes the hook out from the shelf in a state where the hook is locked on the shelf. It is preferable that the locking state of the hook portion with respect to the shelf portion can be immediately released at a desired timing.

In this case, the operation (for example, manual operation) of locking the locking member to the locked portion is easy, while the configuration and arrangement of the unlocking mechanism can be easily selected from a wide range of known techniques.

However, the unlocking mechanism is composed of a slider member provided movably in one direction at the left portion or the right portion, and a slider member provided on the slider member that moves in the one direction. A pushing piece operable to push out the hook portion from above the shelf portion, and a wire connected to the slider member and operable to move the slider member in the one direction. is more preferred.

In this case, by moving the slider member in one direction through the action of the wire, the pushing piece can immediately act to push the hook portion out of the shelf portion, and the cable can be immediately and reliably gripped. can be done.

Alternatively, the unlocking mechanism may include a slider member provided so as to be able to reciprocate at the left portion or the right portion, and a hook portion provided on the slider member and moving in one direction to move the slider member. a pusher piece operable to push the slider member from above the ledge; a wire connected to the slider member and operable to move the slider member in the one direction; and a wire connected to the slider member, the wire It is further preferred to have a return spring operable to move the slider member in the opposite direction and return it to its original position when the action of the spring is released.

In this case also, by moving the slider member in one direction through the action of the wire, the push-out piece can immediately act to push the hook portion out of the ledge portion, and the cable can be immediately and securely gripped. be able to. Furthermore, in this case, after the action of the wire is released, the slider member returns to its original position by the action of the return spring, so that the unlocking mechanism is automatically reset, resulting in improved workability. is high.

Further, in the present invention, the synchronous link has two link bars rotatably connected at one end to each other via a pivot pin, and the pivot pin is connected via an elastic spring. and is connected to the back portion, and the elastic spring biases the pair of moving bodies on the pair of inclined surfaces in a direction to narrow the distance between the pair of elastic bodies via the synchronous link. preferably.

In this case, the cable guiding device can be used horizontally. That is, in the cable guide device of the present invention, in the vertically placed state, when the locking member is immediately released from the locked portion by the locking release mechanism, the cable guiding device can move on the pair of inclined surfaces. A pair of moving bodies can move downward (in a direction to narrow the gap between the pair of elastic bodies) by gravity, and a cable is moved by a pair of elastic bodies arranged on opposing surfaces of the pair of moving bodies so as to face each other. Although it can be grasped immediately and securely, in the horizontal position, such gravitational effects cannot be used. However, when the above feature is adopted, the elastic spring biases the pair of moving bodies on the pair of inclined surfaces in the direction of narrowing the gap between the pair of elastic bodies via the synchronous link. , the direction in which the pair of moving bodies on the pair of inclined surfaces narrows the gap between the pair of elastic bodies by the urging force when the locking state of the locking member with respect to the locked portion is immediately released by the locking release mechanism; , and the cable can be immediately and reliably gripped by the pair of elastic bodies. That is, the action of the biasing force of the elastic spring can be substituted for the action of gravity.

In this case, it is preferable that a plurality of swivel casters are further provided on the back side of the back portion.

According to this, when used in a horizontal position, the cable guide device can easily follow the position at which the cable is pulled out from the cable drum or the position at which the cable is wound.

Alternatively, the present invention provides a left portion and a right portion that provide a pair of slanted surfaces facing each other so that the separation distance on the lower side is small, a back portion to which the left portion and the right portion are fixed, and the A pair of moving bodies disposed facing each other so as to be movable on a pair of inclined surfaces, and a pair of elastic bodies disposed facing each other on the facing surfaces of the pair of moving bodies, wherein the pair of moving bodies , are connected via a synchronous link so as to be movable on the pair of inclined surfaces at the same time in the same direction at the same speed, and the synchronous links are pivoted at one end to each other via a pivot pin. two link bars operatively connected, the pivot pin being connected to the rear portion via a resilient spring, the resilient spring being connected via the synchronizing link to the The cable guide device is characterized in that the pair of moving bodies on the pair of inclined surfaces are urged in a direction to narrow the distance between the pair of elastic bodies.

According to the present invention, the elastic spring biases the pair of moving bodies on the pair of inclined surfaces in the direction of narrowing the gap between the pair of elastic bodies via the synchronous link. In the case of using the cable guide device in a horizontal position, when an abnormality occurs in the cable pulling operation (for example, when the cable pulling force is lost), the pair of moving bodies on the pair of inclined surfaces By the biasing force, the pair of elastic bodies can be moved in a direction to narrow the gap, and the cable can be immediately and reliably gripped by the pair of elastic bodies. That is, the action of the biasing force of the elastic spring can replace the action of gravity in the cable holding device of Patent Document 1.

According to one feature of the present invention, the cable guide device is used in a state in which the locking member is locked to the locked portion in the operation of placing the cable drum on the upper floor and dropping the cable to the lower floor. As a result, the cable can be smoothly guided, and when it becomes necessary to interrupt the cable dropping operation, the locking release mechanism can immediately release the locked state of the locking member from the locked portion. As a result, a pair of moving bodies movable on a pair of inclined surfaces can move downward by gravity, and a pair of elastic bodies disposed opposite each other on the opposing surfaces of the pair of moving bodies move the cable immediately. can be securely gripped.

According to another feature of the present invention, the elastic spring biases the pair of moving bodies on the pair of inclined surfaces in the direction of narrowing the gap between the pair of elastic bodies via the synchronous link. For example, in the case of using the cable guide device horizontally when pulling up the cable, when an abnormality occurs in the operation of pulling up the cable (for example, when the pulling force of the cable is lost), The pair of moving bodies can move in the direction of narrowing the gap between the pair of elastic bodies by the biasing force, and the pair of elastic bodies can immediately and reliably grip the cable.

5, each of the pair of moving bodies 15a and 15b is provided with locking members 18a and 18b that rotate using a pivot shaft 15s that supports the lower roller 15r as a rotation pin. (which also acts as a hand lifter) is provided, and the hook portions 18f of the locking members 18a and 18b can be locked on the inner surface sides of the upper portions of the left and right portions 11a and 11b, respectively. ledges 19a and 19b are provided.

In addition, hooks 32a and 32b are provided via shackles 31a and 31b above the left portion 11a and the right portion 11b, respectively.

Next, referring to FIGS. 6 to 10, in the cable guide device 1 of the present embodiment, when the hook portion 18f of the locking member 18b is locked to the shelf portion 19b as the locked portion, An unlocking mechanism 50 is provided that can immediately release the hook portion 18f from the locking state of the shelf portion 19b at a desired timing.

Specifically, the unlocking mechanism 50 is operated via a wire 51 passing through the upper part of the roller protection wall 12b on the front side. The wire 51 is covered with a wire protection tube 52 so as to be slidable inside in a region on the front side of the roller protection wall 12b.

On the other hand, a guide groove 11g extending in the front-rear direction is provided in the upper inner side of the right portion 11b (see FIG. 10), and a slider member 53 is provided so as to be reciprocally movable within the guide groove 11g.

The slider member 53 is provided with a male screw portion, and the wire 51 is fixed to the slider member 53 via a nut 54 that is screwed with the male screw portion.

By moving the slider member 53 to the front side (the left side in FIGS. 6, 7 and 9, and the upper side in FIGS. 8 and 10), the hook portion 18f is moved to the shelf portion. A pusher piece 55 is provided which is operable to push out from above 19b.

The extruded piece 55 of this embodiment includes a thin plate-like main body portion 55m fixed on the slider member 53, and a rear end (right end in FIGS. 6, 7 and 9, FIG. 8) of the main body portion 55m. and the lower end in FIG. 10), and the front end of the body portion 55m (the left end in FIGS. 6, 7 and 9; and a base end portion 55p extending perpendicularly to the main body portion 55m from the upper end thereof.

In this embodiment, a coil spring 56 is provided between the base end portion 55p of the pushing piece 55 and the roller protection wall 12b. The coil spring 56 can act to move the pushing piece 55 and the slider member 53 rearward and return them to their original positions when the action of the wire 51 is released.

Further, although detailed illustration is omitted, the cable guide device 1 of the present embodiment is configured such that the hook portion 18f of the locking member 18a is locked to the shelf portion 19a as the locked portion, and the hook portion 18f is locked to the hook portion 19a. It also has an unlocking mechanism 50 that can immediately release the locked state of the portion 18f with respect to the shelf portion 19a at a desired timing. The unlocking mechanism 50 for the locking member 18a is arranged symmetrically with the unlocking mechanism 50 for the locking member 18b described above.

[Cable setting to cable guide device 1]
Next, the operation of this embodiment will be described.

Referring to FIG. 3, first, the lock lever 23 is pulled to release the locking function of the buckle member 21, and the right end side of the buckle member 21 is separated from the roller protection wall 12b. Along with this, the engagement between the U-shaped arm member 24 and the arm hook member 27 is released. Thereafter, the front side of the cable guide device 1 is opened by rotating the U-shaped arm member 24 to the right and retracting it.

Next, referring to FIG. 5, locking members 18a and 18b provided on each of the pair of moving bodies 15a and 15b are manually pulled up as hand lifters. Along with this, the pair of moving bodies 15a and 15b are raised along the pair of inclined surfaces S by rolling of the roller 15r, and the gap between the pair of elastic bodies 16a and 16b is widened.

The pair of locking members 18a and 18b are further rotated outward via a pivot shaft 15s as a rotation pin so that each hook portion 18f is positioned above each of the left portion 11a and the right portion 11b. It is locked to the shelf portions 19a and 19b as locked portions. Along with this, the state in which the gap between the pair of elastic bodies 16a and 16b is widened is maintained.

The cable guide device 1 in such a state is hung near the cable C to be held using the hooks 32a and 32b. Then, the cable C to be dropped is positioned so as to pass between the pair of elastic bodies 16a and 16b. (When the cable guide device 1 of this embodiment is set, the engagement between the hook portions 18f of the locking members 18a and 18b and the shelf portions 19a and 19b as locked portions is not released.)

After that, referring to FIG. 3 again, the U-shaped arm member 24 is rotated leftward, and then the buckle member 21 is rotated rightward, so that the U-shaped arm member 24 becomes the arm hook. Engage with member 27 . As a result, the front side of the cable guiding device 1 is closed.

The work of removing the cable C from the cable guide device 1 can also be carried out according to substantially the same procedure as described above.

[Cable holding function by cable guide device 1]
When it becomes necessary to interrupt the cable dropping operation, the pair of left and right unlocking mechanisms 50 immediately releases the locked state of the locking members 18a and 18b from the locked portions (shelf portions) 19a and 19b. .

Specifically, when it becomes necessary to interrupt the cable dropping operation, for example, a known wire pulling mechanism (for example, a brake mechanism of a bicycle) is operated by an operator, and the wire 51 of the unlocking mechanism 50 is pulled into the wire protection pipe. 52 is pulled forward. As a result, the slider member 53 slides forward in the guide grooves 11g (see FIG. 10) of the left portion 11a and the right portion 11b.

As the slider member 53 moves forward, the inclined portion 55t of the pushing piece 55 fixed to the slider member 53 acts to push the hook portion 18f from the shelf portions 19a and 19b (FIG. 9). reference).

When the hook portion 18f is pushed out from the shelf portions 19a and 19b, the pair of movable bodies 15a and 15b that are movable on the pair of inclined surfaces S immediately move downward due to gravity. As a result, the cable C can be immediately and reliably gripped by the pair of elastic bodies 16a and 16b arranged opposite to each other on the opposing surfaces of the pair of moving bodies 15a and 15b.

Once the pair of elastic bodies 16a and 16b grip the cable C, the pair of elastic bodies 16a and 16b gripping the cable C will drop together with the cable C as the cable C drops. and In response to this action, the pair of movable bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tend to move further downward on the pair of inclined surfaces S, respectively. This moving action acts to further narrow the gap between the pair of elastic bodies 16a and 16b, and as a result, the force with which the pair of elastic bodies 16a and 16b hold the cable C increases instantaneously, and the cable C is pulled. Further drop is effectively prevented.

The cable holding force for preventing this further dropping is not greatly affected by the thickness of the cable C. Therefore, regardless of the thickness of the cable C, it is possible to guarantee a sufficient cable holding force for further prevention of dropping, and as a result, a wide range of cable thicknesses can be handled (cable The upper limit of the height is defined by the distance between the pair of inclined surfaces).

The maximum thickness of the cable C that can be held is defined to be approximately 90 mm or less (for example, φ85), which is the minimum separation distance between the pair of inclined surfaces S (see FIG. 11). On the other hand, the minimum thickness of the cable C that can be held depends on the shape of the facing surfaces of the pair of elastic bodies 16a and 16b that are opposed to each other, but as shown in FIG. In some cases, it is of the order of φ15 (see FIG. 12).

[Reset operation of unlocking mechanism 50]
As described above, in this embodiment, the coil spring 56 is provided between the base end portion 55p of the pushing piece 55 and the roller protection wall 12b. The coil spring 56 is compressed when the slider member 53 is slid forward by pulling the wire 51 (see FIG. 9). On the other hand, when the action of the wire 51 is released, the coil spring 56 is released from the compressed state and acts to move the pushing piece 55 and the slider member 53 rearward and return them to their original positions. As a result, the unlocking mechanism 50 is automatically reset, resulting in high workability.

[Summary of effects of the cable guiding device 1]
As described above, according to the cable guide device 1 of the present embodiment, in the work of placing the cable drum on the upper floor and dropping the cable C on the lower floor, the hook portions 18f of the locking members 18a and 18b are the locked portions. By using the cable guide device 1 in a state where it is locked to the shelf portions 19a and 19b as the cable C, it is possible to guide the cable C smoothly. , a pair of moving bodies 15a which can immediately release the locked state of the locking members 18a and 18b from the locked portions 19a and 19b by the locking release mechanism 50 and can move on the pair of inclined surfaces S, respectively; 15b can move downward by gravity, and the cable C can be immediately and reliably gripped by a pair of elastic bodies 16a and 16b arranged opposite to each other on the opposing surfaces of the pair of moving bodies 15a and 15b. .

Once the pair of elastic bodies 16a and 16b grip the cable C, the pair of elastic bodies 16a and 16b gripping the cable C are further dropped together with the cable C as the cable C is dropped. try to. In response to this action, the pair of movable bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tend to move further downward on the pair of inclined surfaces S, respectively. This moving action acts to further narrow the distance between the pair of elastic bodies 16a and 16b. Drop-in is effectively prevented.

The cable holding force for preventing this further dropping is not greatly affected by the thickness of the cable C. Therefore, regardless of the thickness of the cable C, it is possible to guarantee a sufficient cable holding force for further prevention of dropping, and as a result, a wide range of cable thicknesses can be handled (cable The upper limit of the height is defined by the distance between the pair of inclined surfaces S).

The locking members 18a and 18b of the cable guide device 1 of the present embodiment are adapted to rotate via the pivot shaft 15s, and have a hook portion 18f. 19b has a ledge on which the hook 18f can be locked by hooking the hook 18f, and the unlocking mechanism 50 locks the hook 18f on the ledges 19a and 19b. In this state, by pushing the hook portion 18f out from the shelf portions 19a and 19b, the locked state of the hook portion 18 with respect to the shelf portions 19a and 19b can be immediately released at a desired timing.

As a result, the operation (for example, manual operation) of locking the locking members 18a and 18b to the locked portions 19a and 19b is easy, and the unlocking mechanism 50 is also easy to configure and arrange.

In particular, the unlocking mechanism 50 of the present embodiment includes a slider member 53 provided movably in one direction on the left portion 11a or the right portion 11b, and a slider member 53 provided on the slider member 53 to A pushing piece 55 that can act to push the hook portion 18f out of the ledges 19a and 19b by movement in the direction, and a wire that is connected to the slider member 53 and can act to move the slider member 53 in the one direction. 51 and .

As a result, by moving the slider member 53 in the one direction through the action of the wire 51, the pushing piece 55 can immediately act to push out the hook portion 18f from the shelf portions 19a and 19b. C can be grasped reliably immediately.

Further, in the unlocking mechanism 50 of the present embodiment, the slider member 53 is provided so as to be able to reciprocate at the left portion 11a or the right portion 11b. A coil spring 56 (return spring) is provided which can act to move the slider member 53 in the opposite direction and return it to its original position.

As a result, after the action of the wire 51 is released, the slider member 53 is returned to its original position by the action of the coil spring 56, so that the unlocking mechanism 50 is automatically reset, resulting in improved workability. is high.

Furthermore, in the present embodiment, the rotation pin for rotating the locking members 18a and 18b is shared with the pivot shaft 15s for rotatably supporting the roller 15r, thereby suppressing an increase in the number of parts. there is

In addition, since the opening and closing mechanism 20 that covers the movable member is provided on the front side of the left part 11a and the right part 11b, the operator's danger is further reduced, and the undesired disconnection of the set cable C is more reliably prevented. be done.

In addition, the opening/closing mechanism 20 of the present embodiment includes a buckle member 21 with a locking function rotatably provided on the right portion 11b (an example of one of the left portion and the right portion), and a left portion 11a (one of the left portion and the right portion). and a U-shaped arm member 24 rotatably provided on the buckle member 21 . When the locking function is released, the buckle member 21 and the arm member 24 can be rotated to be detachable from the arm hook member 27. When the locking function of the buckle member 21 is activated, it is fixed to the arm hook member 27. It's becoming Therefore, the opening/closing operation of the opening/closing mechanism 20 is extremely simple and safe.

In addition, each of the pair of moving bodies 15a and 15b of the present embodiment moves on the inclined surface S by two sets of rollers, which are vertically spaced apart and which roll on each of the pair of inclined surfaces S. do. As a result, the movement of the moving bodies 15a and 15b on the inclined surface S is extremely smooth and stable.

Also, the pair of moving bodies 15a and 15b of this embodiment are connected via a synchronous link 17 so that they can move on the pair of inclined surfaces S simultaneously in the same direction at the same speed. As a result, the pair of elastic bodies 16a and 16b that grip the cable C also move simultaneously in the same direction at the same speed, so that the cable C can be prevented from dropping more stably.

[Configuration of Cable Guiding Device 101]
Next, a cable guiding device 101 according to a modified embodiment of the invention will be described. The cable guide device 101 of this embodiment is assumed to be used in a horizontal position.

FIG. 13 is a perspective view of the cable guiding device 101 of this embodiment. The rear portion 13 of the cable guiding device 1 described above has a substantially trapezoidal shape, and does not protrude leftward from the left portion 11a nor protrude rightward from the right portion 11b. On the other hand, in the cable guiding device 101 of the present embodiment, as shown in FIG. 13, the rear portion 113 has a rectangular plate shape and protrudes leftward from the left portion 11a and protrudes rightward from the right portion 11b. ing. In addition, the rear portion 113 is larger than the left portion 11a and the right portion 11b in each of the vertical direction (horizontal direction in FIG. 13).

A swivel caster 110 is provided at each of the four corners on the back side (lower side in FIG. 13) of the back portion 113 .

An upper front cable guide roller 121 and an upper rear cable guide roller 122 are provided as a pair on the front side (upper side in FIG. 13) above the rear portion 113 (left side in FIG. 13). Auxiliary rear cable guide rollers 123 are provided slightly below the upper rear cable guide rollers 122 . Further, a lower rear side cable guide roller 124 is provided on the front side (upper side in FIG. 13) below the rear side portion 113 (right side in FIG. 13).

Further, the cable guide device 101 of this embodiment is assumed to be used in a horizontal position, that is, it cannot utilize the moving action of the moving bodies 15a and 15b due to gravity. Therefore, a coil spring 150, which is an example of an elastic spring, is provided to replace the action of gravity.

Specifically, as shown in FIG. 14, the pivot pin 17p also rotatably supports one end of the rotating piece 140, and the connecting hole 140h of the other end of the rotating piece 140 and the connection hole 140h. , and a fixing pin 113 p fixed to the front side of the back portion 113 are connected by a coil spring 150 . As a result, the coil spring 150 biases the pair of movable bodies 15a and 15b on the pair of inclined surfaces S in the direction of narrowing the distance between the pair of elastic bodies 16a and 16b via the synchronous link 17 .

FIG. 14(a) shows a state where no external force is applied (basic state of the coil spring 150), and FIG. 14(c) shows a state in which hook portions 18f of 18a and 18b are engaged with engaged portions 19a and 19b (extended state of coil spring 150), and FIG. 18a and 18b are released from the locked state with respect to the locked portions 19a and 19b, and a state in which, for example, a φ85 cable C is gripped (a state between the basic state and the extended state of the coil spring 150) is shown. there is As shown in FIGS. 14(a) to 14(c), left and right sides of the coil spring 150 are protected by protective walls 160a and 160b.

As shown in FIG. 14, in the cable guide device 101 used in the horizontal position, when the locking release mechanism 50 releases the locked state of the locking members 18a and 18b from the locked portions 19a and 19b, The pair of movable bodies 15a and 15b on the pair of inclined surfaces S can be moved in the direction to narrow the distance between the pair of elastic bodies 16a and 16b by the biasing force (restoring force in this embodiment) of the coil spring 150, The pair of elastic bodies 16a and 16b can immediately and reliably grip the cable C. As shown in FIG. That is, the action of the biasing force (restoring force) of the coil spring 150 can replace the action of gravity.

Other configurations of the cable guide device 101 of this embodiment are substantially the same as those of the cable guide device 1 described with reference to FIGS. 1 to 12 . 13 to 18, portions similar to those of the cable guide device 1 are denoted by similar reference numerals. Further, detailed description of the same parts as those of the cable guide device 1 will be omitted.

[Cable setting to cable guide device 101]
Next, the action of the cable guide device 101 will be described.

As in the cable guide device 1, referring to FIG. 3, first, the lock lever 23 is pulled to release the locking function of the buckle member 21, and the right end side of the buckle member 21 is separated from the roller protection wall 12b. . Along with this, the engagement between the U-shaped arm member 24 and the arm hook member 27 is released. After that, the front side of the cable guiding device 101 is opened by rotating the U-shaped arm member 24 to the right and retracting it.

Next, referring to FIG. 5, locking members 18a and 18b provided on each of the pair of moving bodies 15a and 15b resist the biasing force (restoring force in this embodiment) of coil spring 150. can be manually lifted as a hand lifter. Along with this, the pair of moving bodies 15a and 15b are raised along the pair of inclined surfaces S by rolling of the roller 15r, and the gap between the pair of elastic bodies 16a and 16b is widened.

The pair of locking members 18a and 18b are further rotated outward via a pivot shaft 15s as a rotation pin so that each hook portion 18f is positioned above each of the left portion 11a and the right portion 11b. It is locked to the shelf portions 19a and 19b as locked portions. Along with this, the state in which the gap between the pair of elastic bodies 16a and 16b is widened is maintained.

The cable guide device 101 in such a state is placed, for example, on the floor of the upper floor. Then, the position is adjusted so that the cable C to be dropped passes between the pair of elastic bodies 16a and 16b (and between the upper front cable guide roller 121 and the upper rear cable guide roller 122). See Figure 17).

After that, referring to FIG. 3 again, the U-shaped arm member 24 is rotated leftward, and then the buckle member 21 is rotated rightward, so that the U-shaped arm member 24 becomes the arm hook. Engage with member 27 . As a result, the front side of the cable guiding device 101 is closed.

The work of removing the cable C from the cable guide device 101 can also be carried out according to substantially the same procedure as described above.

[Action of swivel caster 110]
In the cable guide device 101 , swivel casters 110 are provided at the four corners on the back side of the back portion 113 . As a result, as shown in FIG. 15, the cable guide device 101 can easily follow the cable drawing position (or cable winding position) from the cable drum.

[Cable holding function by cable guide device 101]
When it becomes necessary to interrupt the cable dropping operation, the pair of left and right unlocking mechanisms 50 immediately releases the locked state of the locking members 18a and 18b from the locked portions (shelf portions) 19a and 19b. .

Specifically, when it becomes necessary to interrupt the cable dropping operation, for example, a known wire pulling mechanism (for example, a brake mechanism of a bicycle) is operated by an operator, and the wire 51 of the unlocking mechanism 50 is pulled into the wire protection pipe. 52 is pulled forward. As a result, the slider member 53 slides forward in the guide grooves 11g (see FIG. 10) of the left portion 11a and the right portion 11b.

As the slider member 53 moves forward, the inclined portion 55t of the pushing piece 55 fixed to the slider member 53 acts to push the hook portion 18f from the shelf portions 19a and 19b (FIG. 9). reference).

When the hook portion 18f is pushed out from the shelf portions 19a and 19b, the pair of moving bodies 15a and 15b, which are movable on the pair of inclined surfaces S, are immediately pushed downward (see FIG. 13 to the right). As a result, the cable C can be immediately and reliably gripped by the pair of elastic bodies 16a and 16b arranged opposite to each other on the opposing surfaces of the pair of moving bodies 15a and 15b.

Once the pair of elastic bodies 16a and 16b grip the cable C, the pair of elastic bodies 16a and 16b gripping the cable C will drop together with the cable C as the cable C drops. and In response to this action, the pair of movable bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tend to move further downward on the pair of inclined surfaces S, respectively. This moving action acts to further narrow the gap between the pair of elastic bodies 16a and 16b, and as a result, the force with which the pair of elastic bodies 16a and 16b hold the cable C increases instantaneously, and the cable C is pulled. Further drop is effectively prevented.

The cable holding force for preventing this further dropping is not greatly affected by the thickness of the cable C. Therefore, regardless of the thickness of the cable C, it is possible to guarantee a sufficient cable holding force for further prevention of dropping, and as a result, a wide range of cable thicknesses can be handled (cable The upper limit of the height is defined by the distance between the pair of inclined surfaces).

The maximum thickness of the cable C that can be held is defined to be approximately 90 mm or less (for example, φ85), which is the minimum separation distance between the pair of inclined surfaces S (see FIG. 14(c)). As the cable C, a cable consisting of twisted wires of a plurality of cable elements may be used. FIG. 16 shows a plan view of such a cable being gripped.

[Reset operation of unlocking mechanism 50]
Like the cable guide device 1, the cable guide device 101 of this embodiment also has a coil spring 56 between the base end portion 55p of the pushing piece 55 and the roller protection wall 12b. The coil spring 56 is compressed when the slider member 53 is slid forward by pulling the wire 51 (see FIG. 9). On the other hand, when the action of the wire 51 is released, the coil spring 56 is released from the compressed state and acts to move the pushing piece 55 and the slider member 53 rearward and return them to their original positions. As a result, the unlocking mechanism 50 is automatically reset, resulting in high workability.

[Summary of Effects of Cable Guide Device 101]
As described above, according to the cable guide device 101 of the present embodiment, which is used in a horizontal position, the hooks of the locking members 18a and 18b can be used in the operation of placing the cable drum on the upper floor and dropping the cable C on the lower floor. By using the cable guide device 1 in a state where the portion 18f is locked by the shelf portions 19a and 19b as the locked portions, the cable C can be smoothly guided, while the cable dropping operation is reduced. When it is necessary to interrupt, the locking release mechanism 50 can immediately release the locked state of the locking members 18a and 18b from the locked portions 19a and 19b so that they can move on the pair of inclined surfaces S respectively. A pair of moving bodies 15a and 15b can be moved downward by the urging force (restoring force) of the coil spring 150, and a pair of elastic bodies arranged to face each other on the opposing surfaces of the pair of moving bodies 15a and 15b. 16a, 16b allow the cable C to be gripped immediately and securely.

Once the pair of elastic bodies 16a and 16b grip the cable C, the pair of elastic bodies 16a and 16b gripping the cable C are further dropped together with the cable C as the cable C is dropped. try to. In response to this action, the pair of movable bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tend to move further downward on the pair of inclined surfaces S, respectively. This moving action acts to further narrow the distance between the pair of elastic bodies 16a and 16b. Drop-in is effectively prevented.

The cable holding force for preventing this further dropping is not greatly affected by the thickness of the cable C. Therefore, regardless of the thickness of the cable C, it is possible to guarantee a sufficient cable holding force for further prevention of dropping, and as a result, a wide range of cable thicknesses can be handled (cable The upper limit of the height is defined by the distance between the pair of inclined surfaces S).

In addition, the effects of the cable guiding device 1 described in paragraphs 0081 to 0091 can also be obtained in the cable guiding device 101 of this embodiment.

[Other Modes of Use of Cable Guiding Device 101]
The cable guiding device 101 in the horizontal position can also be used for the cable C to be pulled up (see FIG. 18).

In this case, the position is adjusted so that the cable C to be pulled up passes between the pair of elastic bodies 16a and 16b (and between the upper front cable guide roller 121 and the upper rear cable guide roller 122). After that, the engagement between the hook portions 18f of the locking members 18a and 18b and the shelf portions 19a and 19b, which are the locked portions, is manually released in substantially the same manner as in the cable holding device of Patent Document 1, The locking members 18 a and 18 b are manually lowered slowly using the biasing force (restoring force) of the coil spring 150 . Then, the pair of elastic bodies 16a and 16b abut on the cable C to be held.

After that, when the cable C held by the cable guide device 101 loses the lifting force at a portion above the cable guide device 101 due to an accident or the like, the cable C tends to drop due to gravity. At this time, the pair of elastic bodies 16a and 16b gripping the cable C also try to fall together with the cable C due to the frictional force acting between them.

In response to this action, the pair of moving bodies 15a and 15b holding the pair of elastic bodies 16a and 16b tend to move downward on the pair of inclined surfaces S, respectively. This moving action acts to narrow the distance between the pair of elastic bodies 16a and 16b. is effectively prevented.

The cable holding force for this drop prevention depends on the gripping state of the cable C before dropping (for example, the distance between the facing surfaces of the elastic bodies 16a and 16b, that is, the distance between the contact surfaces of the elastic bodies 16a and 16b and the cable C). distance).

As described above, when the cable guide device 101 in a horizontal position is used for the cable C to be pulled up, the coil springs 150 are connected to the pair of moving bodies 15a on the pair of inclined surfaces S via the synchronization link 17. , 15b are urged in the direction of narrowing the gap between the pair of elastic bodies 16a and 16b. The pair of moving bodies 15a and 15b on the pair of inclined surfaces S can be moved in the direction to narrow the distance between the pair of elastic bodies 16a and 16b by the biasing force, and the pair of elastic bodies 16a and 16b immediately move the cable C. can be securely gripped.

[Embodiment of omitting one side of locking members 18a and 18b (or hook portion 18f)]
In each of the above embodiments, the pair of moving bodies 15a and 15b are provided with locking members 18a and 18b that rotate via pivot shafts 15s as rotating pins. Locked portions 19a and 19b to which the locking members 18a and 18b can be locked are provided on the upper portion of each of the right portions 11b.

However, since the pair of moving bodies 15a and 15b are connected via the synchronous link 17 so that they can move on the pair of inclined surfaces S simultaneously in the same direction at the same speed, the locking members 18a and 18b (and one of the locked members 19a and 19b) can be omitted.

That is, at least one of the pair of moving bodies 15a and 15b is provided with a locking member 18a (or 18b) that rotates via a rotating pin, and is mounted above at least one of the left portion 11a and right portion 11b. It is functionally sufficient if there is provided a locked portion 19a (or 19b) to which the locking member 18a (or 18b) can be locked.

In this case, one of the unlocking mechanisms 50 would also be correspondingly omitted.

Alternatively, in order to provide (function as) a hand lifter on both the left and right sides, it is also preferable to provide the locking members 18a and 18b on both the left and right sides, and to provide the hook portion 18f only on one side (one side is omitted). is. Also in this case, the unlocking mechanism 50 corresponding to the omitted hook portion 18f is correspondingly omitted.
