[Description of Embodiments of the Present Invention]

First, the contents of the embodiment of the present invention are listed and described.

As one aspect thereof, the present invention relates to a fusion splicing workbench. The fusion splicing workbench includes a bracket portion for fixing the fusion-splicing body, a mounting portion for mounting the bracket portion, and a support portion supported by the operator, And has a mounting portion and a base portion having an L shape when the connection is performed. Either the bracket portion or the base portion has a neck strap wrapped around the neck of a worker or a coupling portion for coupling a shoulder strap wrapped around the shoulder of an operator. The bracket portion is relatively movable with respect to the mounting portion in the base portion.

According to such a fusion splicing workbench, since the bracket portion is relatively movable with respect to the mount portion in the base portion, the welder main body fixed to the bracket portion can be spaced apart from the operator who supports the support portion in the base portion. Therefore, even if the distance between the point of fusion splicing and the distance of the operator is larger than the conventional one, fusion splicing becomes possible.

The above-described base portion may be a form that can be folded when the fusion splicing is not performed.

Either one of the mounting portion and the bracket portion of the base portion may have a long hole and the mounting portion and the bracket portion of the base portion may be engaged with each other by a stepped screw that is fitted in a long hole.

With this configuration, the bracket can be moved relative to the mounting portion in the base portion by moving the long hole of the stepped screw.

The shoulder strap includes a left shoulder strap and a right shoulder strap corresponding to each of the left and right shoulders of the worker. The left shoulder strap and the right shoulder strap include a shoulder strap, The left shoulder and the right shoulder of the worker are respectively turned around so as to intersect at the back of the worker. One end of the left shoulder strap is an upper left engaging part of the engaging part located at the upper left part of the base part, And the other end of the left shoulder strap is a lower right engaging portion of the engaging portion located at the right lower portion of the base portion (right lower portion) or the bracket portion, and the right lower engaging portion of the left shoulder strap And one end of the right shoulder strap is connected to the right-hand lower engaging portion located at the lower right side of the base portion, And the other end of the right shoulder strap is a lower left engaging portion of the engaging portion located at the lower left portion of the base portion or the left side portion of the bracket portion, And may be coupled to the left lower coupling portion located at the lower left coupling portion.

With this configuration, since the upper left portion of the base portion and the lower right portion of the base portion or the right side portion of the bracket portion are pulled to each other and the upper left portion of the base portion and the left lower portion of the base portion or the left side portion of the bracket portion are pulled to each other, It is possible to suppress the directional shake and the lateral shake, the rotational shake with respect to the vertical axis, and the rotational shake with respect to the horizontal axis.

Either one of the bracket portion and the base portion may have an engaging portion for engaging the shoulder strap and either of the bracket portion and the base portion may have a engaging portion for engaging a torso strap running around the torso of the worker .

According to such a configuration, since the fusion splicing workbench can be supported by the body strap in addition to the support portion and the shoulder strap in the base portion, the stability of the fusion splicing operation can be improved.

At least one of the bracket portion and the base portion may include a magnetic body portion.

The fiber holder for holding the optical fiber may have a magnet on the bottom surface. In this case, it becomes possible to temporarily arrange the optical fibers during the fusion welding operation.

[Detailed Description of Embodiments of the Present Invention]

BEST MODE FOR CARRYING OUT THE INVENTION A fusion splicing workbench according to an embodiment of the present invention will be described below with reference to the drawings. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted. The present invention is not limited to these examples, but is represented by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

2 is a side view of a fusing and connecting workbench according to an embodiment of the present invention, and Fig. 3 is a side view of the fusing and connecting workbench according to the embodiment of the present invention. Fig. And is a rear view of the connection workbench from behind. The fusion splicing workbench 1 shown in Figs. 1 to 3 includes a bracket portion 10, a base portion 20, a neck strap 30, a trunk strap 40, and a coupling member 50 Respectively. 1 to 3 also describe the fusing device main body 5 together with the fusion splicing workbench 1 of the present embodiment.

The bracket portion 10 is for fixing the fuser main body 5 to the base portion 20. The bottom face portion 11 of the bracket portion 10 supports the bottom face of the fusing device body 5 via the cushioning material 60. [ The front side edge, left side, right side edge, and rear side edge of the bottom face portion 11 are provided with folded back portions 12, 13, and 14, respectively.

The folded back portion 12 has a folded portion 12a upward from the central portion occupying about one third of the front side edge of the bottom face portion 11 and a folded portion 12b extending from the portion 12a toward the bottom face 11 And a folded portion 12b facing the portion. That is, the portion 12a extends from the central portion occupying approximately one-third of the front side edge of the bottom face portion 11 to the center portion occupying approximately one-third of the front face of the fuser body 5, (12b) extends from the portion (12a) to cover a part of the front surface side of the upper surface of the fuser body (5). The folded back portion 12 supports a part of the front surface of the fuser body 5 and the front surface of the fuser body 5 via the cushioning material 60.

The folded back portion 13 is folded back upward from the central portion occupying about three-fifths of the lateral edges of the bottom face portion 11 and is folded upwardly along the side face of the fuser body 5 Lt; / RTI >

The folded back portion 14 is folded back upward from the central portion occupying about one-fifth of the rear edge of the bottom portion 11. A screw 14a is provided on the upper portion of the return folded portion 14 and the front end of the screw 14a supports the rear face of the fusing device body 5 via the buffer material 60. [

By the folded back portions 12, 13 and 14, the fuser main body 5 is fixed. More specifically, the fusing device main body 5 is mounted on the bottom face portion 11 while the front face of the fusing device main body 5 is hooked on the folded portion 12, and the screw 14a of the folded back portion 14 is fastened The fusing device main body 5 is fixed to the bracket portion 10. As the screw 14a, it is also possible to use a stepped screw or the like to restrict the amount of conveyance (prevention of over-tightening).

The bracket portion 10 is mounted on the base portion 20. The base portion 20 has a mounting portion 21, a support portion 22, and a hinge 23.

The mounting portion 21 is a portion for mounting and fixing the bracket portion 10, and has a substantially flat plate shape. The mount portion 21 is detachably mountable to the bracket portion 10 as described later and fixes the bracket portion 10 movably in the forward and backward directions X in the mounted state. The length of the mounting portion 21 in the forward and backward directions X is longer than the length of the bracket portion 10 in the forward and backward directions X or the longitudinal direction X of the fuser main body 5.

Further, the mounting portion 21 has a folded back portion 21a which is folded upward from the transverse edge. The folded back portion 21a functions as a guide for moving the bracket portion 10 in the forward and backward directions X and prevents lateral displacement and rotation of the bracket portion 10. [

The support portion 22 is a portion to be supported by an operator and has a substantially flat plate shape. The support portion 22 has a hole (engagement portion) 22a on the left and right side of the upper end portion and a neck strap 30 and a body strap 40 are coupled to the hole 22a.

The neck strap 30 is held on the neck of the worker to suspend and support the fusion splicing workbench 1. The body strap 40 supports the fusion splicing workbench 1 by being pivoted around the body of the worker. Further, the body strap 40 is not necessarily provided. For this reason, for example, the body strap 40 is joined via a detachable coupling member such as a hook. On the other hand, it is preferable that the neck strap 30 is coupled via a non-removable joining member such as a ring. The neck straps 30 and the body straps 40 may be adjustable in length depending on the worker's physique.

In the present embodiment, the neck strap 30 and the body strap 40 are coupled to the same hole 22a in the support portion 22. [ As a result, the fulcrum of the neck strap 30 and the position of the body strap 40 can be made the same, and longitudinal shaking of the fusing workbench can be suppressed.

The mounting portion 21 and the support portion 22 are coupled to each other by a hinge 23. Thus, at the time of fusion splicing operation, the base portion 20 is fixed in a substantially L-shaped configuration, and it is possible to carry out the work while being supported by the operator. On the other hand, at the time of not working, the base portion 20 can be folded in a substantially V-shape with the fuser body 5 and the bracket portion 10 mounted thereon. Further, in a state in which the fusing device main body 5 and the bracket portion 10 are separated, the base portion 20 can be folded in two in a substantially I-shape.

As the hinge 23, a free stop hinge may be used. According to this, the angle of the base portion 20 can be adjusted, and the degree of freedom of the operation is further increased.

Next, a structure for fixing the bracket portion 10 to the mount portion 21 of the base portion 20 will be described with reference to Figs. 4 to 6. Fig. 4 is a bottom view of the mounting portion 21 of the base portion 20 partially enlarged and viewed from the bottom. Fig. 5 is a sectional view taken along the line VV in Fig. 4 and shows the bracket portion 10 and the base portion 5 is a sectional view taken along the line VI-VI in Fig. 4 and shows a mounting portion 21 in the bracket portion 10 and the base portion 20, (21).

The mounting portion 21 of the bracket portion 10 and the base portion 20 is engaged by the engaging member 50 comprising the stepped screw 51, the nut 52 and the washer 53. [

Specifically, the bottom face portion 11 of the bracket portion 10 has a hole 11a at a substantially central portion thereof. On the other hand, the mounting portion 21 of the base portion 20 has an elongated hole 21b extending in the forward and backward directions X. A stepped screw 51 is held in this hole 21b. Specifically, by providing the washer 53 on the side opposite to the head of the screw 51 with respect to the base portion 20, the stepped screw 51 is held in the hole 21b. The stepped screw 51 is inserted into the hole 11a of the bracket portion 10 and the base portion 20 and is engaged by the nut 52. Further, the washer 53 is interposed between the bracket portion 10 and the base portion 20. The washer 53 may be provided between the screw 51 and the mounting portion 21. [

The stepped screw 51 coupled to the bracket portion 10 through the hole 11a can move through the elongated hole 21b of the mounting portion 21 of the base portion 20, As a result, the bracket portion 10 is relatively movable with respect to the mounting portion 21 of the base portion 20. [ The stepped screw 51 and the nut 52 enable the bracket part 10 to be detachable from the mounting part 21 of the base part 20. [

It is preferable that a lightweight material is used for the bracket portion 10 and a material that has strong mechanical strength and is more fitting to the human body is used as the base portion 20. [ According to this configuration, the entire working table can be made to have the optimum weight, and the center of the work table can be suppressed to a small inertia moment with respect to the worker side, thereby enhancing the stability of the fusion splicing operation.

Further, a magnetic material may be used as the base portion 20. As a result, when the magnets are provided on the lower surface of the fiber holder for holding the optical fibers, it is possible to arrange the optical fibers temporarily during the fusion splicing operation.

Further, a sliding member 70 may be interposed between the mounting portion 21 and the bracket portion 10. For example, when the ease of movement in the forward and backward directions X is emphasized, a material having a low coefficient of friction may be used as the sliding member 70. In order to prevent inadvertent sliding, A material having a high coefficient of friction may be used. In this case, the sliding member 70 is mounted on the bracket portion 10 side. This makes it possible to increase the cushioning property of the bottom surface of the bracket portion 10 so that the fusing device main body 5 can be used even in a configuration in which the bracket portion 10 is not mounted on the base portion 20.

Since the bracket portion 10 can be relatively moved with respect to the mount portion 21 of the base portion 20 according to the fusion splicing workbench 1 of the present embodiment, 5 can be spaced apart from an operator who supports the support portion 22 of the base portion 20. [ Therefore, even if the distance between the fusion splicing point (for example, a closure or the like) and the operator is large compared to the conventional one, fusion splicing becomes possible. This effect is further exerted, for example, in a small and thin fusion welding machine.

According to the fusion splicing workbench 1 of the present embodiment, since the fusing device body 5 is fixed to the bracket portion 10 and the coupling structure with respect to the base portion 20 is provided on the bracket portion 10, It is not necessary to provide a mechanism (for example, a screw hole) for mounting (and sliding) in the main body 5. [ As a result, it is possible to reduce the size and weight of the main body 5 of the fusing device. For example, in an environment in which a workbench is not used, it is possible to use the fusing device main body 5 by taking advantage of its small size and light weight. As described above, it is possible to use the fusing device body 5 in the optimum use environment in each of the case of using the workbench and the case of not using the workbench.

According to the fusion splicing workbench 1 of the present embodiment, since the bracket portion 10 and the base portion 20 can be separated from each other, the bracket portion 10 can be designed The fusing device main body 5 can be housed in the accommodating case with the bracket portion 10 mounted thereon. Further, the base portion 20 can be folded in two and accommodated in the accommodating case. It is also possible to easily mount the bracket portion 10 integrated with the fusing device body 5 by the engaging member 50 after the base portion 20 is opened and mounted in an L shape at the time of use .

According to the fusion splicing workbench 1 of the present embodiment, when a plurality of fusion machine bodies 5 are used, a plurality of bracket parts 10 corresponding to each fusion machine body 5 are prepared and attached , It is possible to easily use a plurality of fusing unit bodies 5 in one base portion 20. [

Since the stepped screw 51 is held in the hole 21b of the mounting portion 21 of the base portion 20 according to the fusion bonding work table 1 of the present embodiment, Detachment and movement of the bracket portion 10 with respect to the base 10 can be facilitated.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the present embodiment, a long hole 21b is provided on the side of the base portion 20, but it may be provided on the side of the bracket portion 10 as well.

Although the engaging member 50 is held on the side of the base portion 20 in the present embodiment, it may be held on the bracket portion 10 side. In this case, in place of the elongated hole 21b, the mounting portion 21 of the base portion 20 may be provided with a groove having one of the elongated holes 21b opened (Fig. 7 (FIG. 7 (a)) and a long hole having a shape in which one of the elongated holes 21b is larger than the head diameter of the stepped screw 51 (FIG. 7 (b)).

In this embodiment, both the neck strap 30 and the body strap 40 are provided. However, in the case where the stabilization of the fusion splicing operation can be achieved by simply providing the neck strap 30, 8 to 10, the body strap 40 is not necessarily provided.

The neck strap 30 provided on the support portion 22 of the base portion 20 and the hole (engagement portion) 22a for the body strap 40 may be elongated holes (slits). In this case, the neck strap 30 or the body strap 40 of the belt-like shape is inserted into the long hole 22a of the support portion 22 of the base portion 20 without passing through the engagement member such as a hook or a ring And can be mounted directly.

8 to 10, a ring 22a for the neck strap 30 and the body strap 40 is provided in the support portion 22 of the base portion 20 in place of the hole 22a. The engaging member 21c may be provided.

In the present embodiment, the neck strap 30 and the body strap 40 are mounted on the upper end of the support portion 22 of the base portion 20. However, as shown in Figs. 8 to 10 The neck strap 30 and the body strap 40 may be mounted on the mounting portion 21 of the base portion 20. [ Further, the neck strap 30 and the body strap 40 may be mounted on the bracket portion 10 side. In this manner, it is sufficient that the fusion splicing operation is stable, and the mounting position of the neck strap 30 and the body strap 40 is not limited to this embodiment.

The neck strap 30 and the body strap 40 may be made the same in the present embodiment, but the point of the neck strap 30 and the body strap 40 may be different from each other . In this case, the supporting portion 22 of the base portion 20 is provided with one hole (coupling portion) 22a at the left and right side of the upper end portion thereof, and the neck strap 30 and the body strap 40, And may be coupled to the respective holes on the right and left sides of the upper end. The support portion 22 of the base portion 20 is provided with one hole (coupling portion) 22a on the left and right sides of the lower end portion thereof, and the body strap 40 is provided on the right and left side of the lower end portion It is good to be connected to the hole.

Hereinafter, with reference to FIG. 11 (a) and FIG. 11 (b), the advantages of these structures will be compared and explained. (The present embodiment) in the case where the point of the neck strap 30 and the point of the body strap 40 are the same position as shown in FIG. 11A and the support portion 22 The peripheral portion of the operator's chest can be stabilized and the longitudinal shaking of the fusing and connecting workbench can be suppressed. On the other hand, the lower portion of the base portion 20, that is, the side of the mounting portion 21 It is relatively difficult to suppress lateral shaking. In this case, a Y-axis orthogonal to the front-rear direction X, that is, a Y-axis perpendicular to the main surface of the mount 21 and extending in the longitudinal direction at substantially the center at the left and right along the main surface of the support 22 (Indicated by an arrow in the figure) with respect to the rotation of the rotating shaft. Rotation fluctuations (indicated by arrows in the figure) with respect to the Z-axis perpendicular to the Y-axis, that is, the Z-axis (horizontal axis) extending along the joining line between the mount portion 21 and the support portion 22 It is relatively difficult to suppress.

On the other hand, when the point of the neck strap 30 and the point of the body strap 40 are apart from each other as shown in Fig. 11 (b), the circumference of the waist of the operator is stabilized and the rotation of the fusion splicing workbench is suppressed So that it is possible to suppress the rotation fluctuation with respect to the Y-axis and the Z-axis. However, in such a case, it is relatively difficult to suppress longitudinal shaking of the fusion splicing workbench. For example, since the point of the neck strap 30 and the point of the body strap 40 are apart, they tend to collapse before slanting forward.

Thus, as shown in Fig. 12 (a), two body straps 40, which are respectively coupled to the right and left side portions of the upper end portion of the support portion 22 in the base portion 20 and the right and left side portions of the lower end portion, Like body strap (not shown) coupled to the left and right sides of the lower end portion of the upper end portion of the upper end portion of the support portion 22 in the base portion 20 as shown in Fig. 12 (b) 40 may be provided. According to these configurations, it is possible to stabilize the circumference of the operator's body and the periphery of the waist, and also to suppress longitudinal shaking and rotational shake of the fusion splicing workbench, and also to suppress the rotational shaking with respect to the Y axis and the Z axis.

13, a shoulder strap 80 may be used in place of the neck strap 30 and the body strap 40. [0064] The shoulder strap 80 includes a left shoulder strap 81 and a right shoulder strap 82 corresponding to each of the left and right shoulders of the operator and includes a left shoulder strap 81 and a right shoulder strap 82, The left shoulder and the right shoulder of the worker are respectively circulated so as to intersect at the back part of the worker. That is, the left shoulder strap 81 extends from the left shoulder of the operator through the back to the right side, and the right shoulder strap 82 extends from the right shoulder of the operator through the back to the left side box).

One end of the left shoulder strap 81 is an upper left hole of the hole 22a located on the left side of the upper end of the support portion 22 of the base portion 20 and is located on the left shoulder side of the operator And the other end of the left shoulder strap 81 is a hole on the lower right side of the hole 22a positioned on the right side of the lower end of the support portion 22 of the base portion 20, And is coupled to a hole located below the right side of the operator.

On the other hand, one end of the right shoulder strap 82 is a hole on the upper right side of the hole 22a located on the right side of the upper end of the support portion 22 of the base portion 20, And the other end of the right shoulder strap 82 is connected to the hole located at the left shoulder side of the lower end portion of the support portion 22 of the base portion 20, And is engaged with a hole located below the left armpit of the operator.

According to such a configuration, the upper left portion of the base portion and the lower right portion of the base portion are pulled together, and the upper right portion of the base portion and the lower left portion of the base portion are pulled to each other. Thus, longitudinal and lateral shaking And it is also possible to suppress the rotation fluctuation with respect to the Y-axis and the Z-axis.

The other end of the left shoulder strap 81 is connected to the side of the mounting portion 21 located below the base portion 20 in place of the right side of the lower end portion of the supporting portion 22 of the base portion 20. [ And the other end of the right shoulder strap 82 may be connected to the left side of the lower end of the support portion 22 of the base portion 20 It may be connected to the left side of the mounting portion 21 located at the lower portion of the base portion 20 or to the left side of the bracket portion 10 instead of the base portion 20. In addition, the left shoulder strap 81 and the right shoulder strap 82 may alternately run around the left shoulder and the right shoulder of the worker without crossing at the back of the worker. That is, the other end of the left shoulder strap 81 may be coupled to the left side of the lower end of the support portion 22 of the base portion 20, and the other end of the right shoulder strap 82 may be connected to the base portion 20 on the right side of the lower end of the support portion 22. [

The left shoulder strap 81 and the right shoulder strap 82 may be joined at the intersection 83. As the bonding method, for example, a bonding member may be used, or bonding or sealing (sewing) may be used. According to this, since the loops around the neck are formed by the left shoulder strap 81 and the right shoulder strap 82, an action of preventing the falling of the fusion splicing workbench is obtained.

Further, the left shoulder strap 81 and the right shoulder strap 82 may each be provided with a coupling member 84 for two-division. The coupling member 84 may be a buckle or the like. This makes it easy to attach and detach the fusion splicing workbench. In this case, one end and the other end of the left shoulder strap 81 and one end and the other end of the right shoulder strap 82 may be detachably coupled to the base portion 20 or the bracket portion 10, respectively. In consideration of the action of the intersection 83 described above, the engaging member 84 is positioned below the intersection 83 (for example, at a position corresponding to the waist of the operator, (I.e., in the vicinity of the boundary between the mounting portion 21 and the supporting portion 22).

Each of the left shoulder strap 81 and the right shoulder strap 82 may be provided with an adjusting member 85 for adjusting the length. As the adjustment member 85, a rudder buckle or the like may be used. Thus, the length can be adjusted according to the worker's physique. The adjusting member 85 can be attached and detached by lengthening the left shoulder strap 81 and the right shoulder strap 82 by the adjusting member 85. Therefore, As shown in Fig. The adjustment member 85 is disposed at a position below the intersection 83 (for example, at a position corresponding to the waist of the operator, or at a position corresponding to the mounting portion 21 and the support portion 21 in the base portion 20) (In the vicinity of the boundary of the intersection portion 22), or may be provided on the upper side of the intersection portion 83.
