FIG. 1 is a plan view of a fusion splicing work table according to an embodiment of the present invention as seen from above, and FIG. 2 is a side view of the fusion splicing work table according to an embodiment of the present invention as viewed from the side. FIG. 3 is a rear view of the fusion splicing work table according to the embodiment of the present invention as seen from the rear. The fusion splicing work table 1 shown in FIGS. 1 to 3 includes a bracket portion 10, a base portion 20, a neck strap 30, a torso strap 40, and an engaging member 50. 1 to 3 also show the fusion machine main body 5 together with the fusion splicing work table 1 of the present embodiment.

The bracket part 10 is for fixing the fuser body 5 to the base part 20. The bottom surface portion 11 of the bracket portion 10 supports the bottom surface of the fuser main body 5 with a cushioning material 60 interposed therebetween. Folded

portions

12, 13, and 14 are formed on the front side edge, the left and right side side edges, and the rear side edge of the bottom surface part 11, respectively.

The folded portion 12 includes a portion 12a folded upward from a central portion that occupies about one third of the front edge of the bottom surface portion 11, and a portion 12b folded so as to face a part of the bottom surface portion 11 from the portion 12a. And have. That is, the portion 12a extends from the central portion that occupies about one third of the front side edge of the bottom surface portion 11 along the central portion that occupies about one third of the front surface of the fuser body 5, and the portion 12b. Extends from the portion 12 a so as to cover a part of the front surface side of the upper surface of the fuser body 5. The folded portion 12 supports a part of the front side of the fuser body 5 and the front side of the upper surface with the cushioning material 60 interposed therebetween.

Moreover, the folding | returning part 13 is turned up from the center part which occupies about 3/5 of the lateral side edge in the bottom face part 11, and supports the side surface of the melter main body 5 through the buffer material 60.

Further, the folded portion 14 is folded upward from a central portion that occupies about one fifth of the rear side edge of the bottom surface portion 11. A screw 14 a is provided on the upper portion of the folded portion 14, and the tip of the screw 14 a supports the rear surface of the fuser main body 5 through the buffer material 60.

The fusion machine main body 5 is fixed by these

folding portions

12, 13, and 14. Specifically, the fuser body 5 is mounted on the bottom surface portion 11 while the front surface of the fuser body 5 is hooked on the folded portion 12, and the screw 14 a of the folded portion 14 is tightened to be fused to the bracket portion 10. The machine body 5 is fixed. As the screw 14a, a stepped screw or the like may be used to limit the feed amount (prevents overtightening).

The bracket unit 10 is mounted on the base unit 20. The base part 20 includes a mounting part 21, a support part 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. As will be described later, the mounting portion 21 fixes the bracket portion 10 so as to be detachable and movable in the front-rear direction X in the mounting state. Therefore, the length of the mounting portion 21 in the front-rear direction X is longer than the length of the bracket portion 10 in the front-rear direction X, that is, the length of the fuser body 5 in the front-rear direction X.

The mounting portion 21 has a folded portion 21a folded upward from the lateral side edge. This folding | returning part 21a functions as a guide at the time of moving the bracket part 10 to the front-back direction X, and prevents the horizontal displacement and rotation of the bracket part 10. FIG.

The support portion 22 is a portion that is supported by an operator and has a substantially flat plate shape. The support portion 22 has holes (engagement portions) 22a on the left and right sides of the upper end portion, and the neck strap 30 and the torso strap 40 are engaged with the holes 22a.

The neck strap 30 suspends and supports the fusion splicing work table 1 by being wrapped around the operator's neck. The torso strap 40 supports the fusion splicing work table 1 by being wrapped around the operator's torso. Note that the trunk strap 40 is not necessarily provided. Therefore, for example, the trunk strap 40 is engaged via a detachable engagement member such as a hook. On the other hand, the neck strap 30 is preferably engaged via a non-detachable engagement member such as a ring. The lengths of the neck strap 30 and the torso strap 40 may be adjustable according to the physique of the operator.

In the present embodiment, the neck strap 30 and the torso strap 40 are engaged with the same hole 22 a in the support portion 22. Thereby, the fulcrum of the neck strap 30 and the fulcrum of the trunk strap 40 can be made the same, and the vertical runout of the fusion work table can be suppressed.

These mounting portion 21 and support portion 22 are engaged by a hinge 23. Thereby, at the time of fusion splicing work, the base portion 20 is fixed in a substantially L shape, and the work can be performed while being supported by the operator. On the other hand, when not working, the base portion 20 can be folded into a substantially V shape with the fuser body 5 and the bracket portion 10 mounted. In addition, in the state where the fuser main body 5 and the bracket portion 10 are removed, the base portion 20 can be folded in half in a substantially I shape.

As the hinge 23, a free stop hinge may be used. According to this, the angle adjustment of the base part 20 is possible, and the freedom degree of work increases more.

Next, a structure for fixing the bracket portion 10 to the mounting portion 21 in the base portion 20 will be described with reference to FIGS. 4 is a bottom view of the mounting portion 21 of the base portion 20 partially enlarged and viewed from below. FIG. 5 is a cross-sectional view taken along the line VV in FIG. 5 is a partially enlarged view of the mounting portion 21 in the portion 20, and FIG. 5 is a cross-sectional view taken along the line VI-VI in FIG. 4 and shows a part of the mounting portion 21 in the bracket portion 10 and the base portion 20. FIG.

The bracket portion 10 and the mounting portion 21 in the base portion 20 are engaged by an engaging member 50 including a stepped screw 51, a nut 52, and a washer 53.

Specifically, the bottom surface portion 11 of the bracket portion 10 has a hole 11a at a substantially central portion. On the other hand, the mounting portion 21 of the base portion 20 has a long hole 21 b extending in the front-rear direction X. A stepped screw 51 is held in the hole 21b. Specifically, by providing a 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 bracket portion 10 and the base portion 20 are engaged with each other by a nut 52 after the stepped screw 51 is inserted into the hole 11a. The washer 53 is interposed between the bracket portion 10 and the base portion 20. The washer 53 may be located between the screw 51 and the mounting portion 21.

Thereby, the stepped screw 51 engaged with the bracket portion 10 through the hole 11a can move through the long hole 21b of the mounting portion 21 in the base portion 20, and as a result, the bracket portion 10 The base portion 20 can move relative to the mounting portion 21. Further, the bracket portion 10 can be separated from the mounting portion 21 in the base portion 20 by the stepped screw 51 and the nut 52.

In addition, it is preferable that a lightweight material is used for the bracket portion 10 and a material that has a high mechanical strength and fits the human body is used for the base portion 20. According to this, it is possible to make the entire workbench an optimum weight, and to bring the center of gravity of the workbench toward the worker side and to suppress the moment of inertia to a small level, thereby improving the stability of the fusion splicing work.

Further, a magnetic material may be used as the base portion 20. Thereby, when the magnet is provided on the lower surface of the fiber holder that holds the optical fiber, the optical fiber can be temporarily placed during the fusion splicing operation.

Further, a sliding material 70 may be interposed between the mounting portion 21 and the bracket portion 10. For example, as the sliding member 70, when importance is attached to the ease of movement in the front-rear direction X, a material having a low friction coefficient may be used, or the sliding member 70 slides carelessly with an emphasis on ensuring safety. In order to prevent this, a material having a high friction coefficient may be used. In this case, the sliding member 70 is attached to the bracket part 10 side. Thereby, the cushioning property of the bottom face of the bracket part 10 is improved, and the fuser body 5 can be used even in a form in which the bracket part 10 is not attached to the base part 20.

According to the fusion splicing work table 1 of the present embodiment, since the bracket portion 10 is movable relative to the mounting portion 21 in the base portion 20, the fusion machine main body 5 fixed to the bracket portion 10 is provided. The operator can support the support portion 22 in the base portion 20. Therefore, the fusion splicing is possible even if the distance between the fusion splicing point (for example, a closure or the like) and the worker is larger than the conventional distance. This effect is more exhibited in, for example, a small and thin fusion machine.

Further, according to the fusion splicing work table 1 of the present embodiment, the fusion machine main body 5 is fixed to the bracket portion 10 and the engagement structure for the base portion 20 is provided in the bracket portion 10. It is not necessary to provide a mechanism (for example, screw hole) for mounting (and sliding). As a result, the fuser body 5 can be reduced in size and weight. For example, in an environment that does not use a work table, the fuser body 5 can be used by taking advantage of the small size and light weight. As described above, the fuser body 5 can be used in an optimum use environment in each of the case where the work table is used and the case where the work table is not used.

Further, according to the fusion splicing work table 1 of the present embodiment, since the bracket portion 10 and the base portion 20 can be separated, the bracket portion 10 is designed so as to have substantially the same bottom area as the fusion machine body 5. By doing so, the fuser body 5 can be accommodated in the accommodation case with the bracket portion 10 attached at the time of accommodation. Moreover, the base part 20 can be folded in half and accommodated in a storage case. On the other hand, in use, the base portion 20 can be opened and mounted in an L shape, and then the bracket portion 10 integrated with the fuser main body 5 can be easily attached by the engaging member 50.

Further, according to the fusion splicing work table 1 of the present embodiment, when a plurality of fusion machine main bodies 5 are used, a plurality of bracket portions 10 corresponding to the respective fusion machine main bodies 5 are prepared and attached respectively. As a result, a plurality of fuser main bodies 5 can be easily used with one base portion 20.

Further, according to the fusion splicing work table 1 of the present embodiment, the stepped screw 51 is held in the hole 21 b of the mounting portion 21 of the base portion 20, so that the bracket portion 10 can be attached to and detached from the mounting portion 21 of the base portion 20. Easy to move.

The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the present embodiment, the elongated hole 21b is provided on the base portion 20 side, but may be provided on the bracket portion 10 side.

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

Further, in the present embodiment, an example in which both the neck strap 30 and the torso strap 40 are provided is illustrated. However, when the fusion splicing operation can be stabilized only by providing the neck strap 30, FIGS. As shown in FIG. 3, the trunk strap 40 is not necessarily provided.

Further, the hole (engagement portion) 22a for the neck strap 30 and the trunk strap 40 provided in the support portion 22 in the base portion 20 may be a long hole (slit). In this case, the belt-like neck strap 30 or the trunk strap 40 can be directly attached to the elongated hole 22a of the support portion 22 in the base portion 20 without using an engaging member such as a hook or a ring.

Further, as shown in FIGS. 8 to 10, the support portion 22 of the base portion 20 may be provided with an engagement member 21c such as a ring for the neck strap 30 and the trunk strap 40, instead of the hole 22a. .

In the present embodiment, the neck strap 30 and the torso strap 40 are illustrated as being attached to the upper end portion of the support portion 22 in the base portion 20, but the neck strap 30 and the torso strap 40 are shown in FIGS. May be attached to the mounting portion 21 in the base portion 20. Further, the neck strap 30 and the torso strap 40 may be attached to the bracket portion 10 side. Thus, the stability of the fusion splicing work only needs to be obtained, and the attachment positions of the neck strap 30 and the torso strap 40 are not limited to this embodiment.

Further, in the present embodiment, the form in which the fulcrum of the neck strap 30 and the fulcrum of the trunk strap 40 are made the same is illustrated, but the fulcrum of the neck strap 30 and the fulcrum of the trunk strap 40 may be different. In this case, the support portion 22 of the base portion 20 is further provided with holes (engagement portions) 22a one by one on the left and right sides of the upper end, and the neck strap 30 and the trunk strap 40 are on the left and right sides of the upper end. In this case, it is only necessary to engage with separate holes. Alternatively, the support portion 22 in the base portion 20 is further provided with holes (engagement portions) 22a one by one on the left and right sides of the lower end, and the trunk strap 40 is engaged with the holes on the left and right sides of the lower end. It only has to be done.

Hereinafter, the advantages of these configurations will be described in comparison with reference to FIGS. As shown in FIG. 11A, when the fulcrum of the neck strap 30 and the fulcrum of the torso strap 40 are at the same position (this embodiment), the left and right sides of the upper end of the support 22 in the base 20 In this case, the chest part of the operator is stable, and the vertical runout of the fusion splicing workbench can be suppressed. On the other hand, the lateral shake of the lower part of the base part 20, that is, the mounting part 21, can be suppressed relatively. Have difficulty. In this case, the Y axis perpendicular to the front-rear direction X, that is, the Y axis (vertical axis) perpendicular to the main surface of the mounting portion 21 and extending in the vertical direction at the center of the left and right along the main surface of the support portion 22. ) Is relatively difficult to suppress. Further, the Z axis orthogonal to the front and rear directions X and Y axes, that is, the Z axis (horizontal axis) extending along the connecting line between the mounting portion 21 and the support portion 22 is suppressed (shown by arrows in the figure). It is relatively difficult.

On the other hand, as shown in FIG. 11B, when the fulcrum of the neck strap 30 and the fulcrum of the torso strap 40 are separated from each other, the waist of the operator is stabilized and the lateral swing of the fusion splicing work table is suppressed. Thus, it is possible to suppress the whirling with respect to the Y axis and the Z axis. However, in this case, it is relatively difficult to suppress the vertical runout of the fusion splicing work table. For example, since the fulcrum of the neck strap 30 and the fulcrum of the torso strap 40 are separated from each other, it is easy to fall forward when tilted forward.

Therefore, as shown in FIG. 12 (a), there are two trunk straps 40 that are respectively engaged with the left and right sides of the upper end portion of the support portion 22 and the left and right sides of the lower end portion of the base portion 20. As shown in FIG. 12 (b), it has a belt-like body strap 40 engaged from the left and right sides of the upper end portion of the support portion 22 to the left and right sides of the lower end portion of the base portion 20. It may be. According to these configurations, the waist circumference and waist circumference of the operator are stable, and the vertical runout and lateral runout of the fusion splicing work table can be suppressed, and the runout with respect to the Y axis and the Z axis can also be suppressed.

Further, as shown in FIG. 13, a shoulder strap 80 may be used instead of the neck strap 30 and the torso strap 40. The shoulder strap 80 includes a left shoulder strap 81 and a right shoulder strap 82 corresponding to the left and right shoulders of the operator, respectively, so that the left shoulder strap 81 and the right shoulder strap 82 intersect at the back of the operator. , Around the left shoulder and right shoulder of the worker. That is, the left shoulder strap 81 extends from the worker's left shoulder through the back to the right flank, and the right shoulder strap 82 extends from the worker's right shoulder through the back to the left flank ( )

One end of the left shoulder strap 81 is an upper left hole of the holes 22a located on the left side of the upper end portion of the support portion 22 in the base portion 20, and engages with a hole located on the left shoulder side of the operator. The other end of the left shoulder strap 81 is a lower right hole of the holes 22a located on the right side of the lower end portion of the support portion 22 in the base portion 20, and is positioned below the operator's right side. Is engaged with the hole.

On the other hand, one end of the right shoulder strap 82 is an upper right hole of the holes 22a located on the right side of the upper end portion of the support portion 22 in the base portion 20, and is a hole located on the right shoulder side of the operator. The other end of the right shoulder strap 82 is a lower left hole of the holes 22a located on the left side of the lower end portion of the support portion 22 in the base portion 20, and is the left of the operator. It engages with a hole located below the side.

According to this configuration, the upper left part of the base part and the lower right part of the base part attract each other, and the upper right part of the base part and the lower left part of the base part attract each other. Lateral run-out can be suppressed, and swinging with respect to the Y-axis and Z-axis can also be suppressed.

Note that the other end of the left shoulder strap 81 is replaced with the right side of the lower end portion of the support portion 22 in the base portion 20, or on the right side of the mounting portion 21 located at the lower portion of the base portion 20 or the bracket portion 10. The other end of the right shoulder strap 82 may be positioned on the lower side of the base portion 20 instead of the left side of the lower end portion of the support portion 22 in the base portion 20. The left side of the mounting part 21 or the left side of the bracket part 10 may be engaged. Further, the left shoulder strap 81 and the right shoulder strap 82 may circulate around the operator's left shoulder and right shoulder without crossing at the operator's back. That is, the other end of the left shoulder strap 81 may be engaged with the left side of the lower end portion of the support portion 22 in the base portion 20, and the other end of the right shoulder strap 82 is engaged with the base portion 20.

However, the bracket part 10 from which the fuser main body 5 has been removed may be accommodated in a state of being attached to the base part 20. An example is shown below.

FIG. 14 is a side view of the bracket portion 10 according to a modification of the present embodiment, viewed from the side when the fuser body 5 is mounted, and FIG. 15 is a bracket portion shown in FIG. FIG. 10 is a perspective view showing the bracket portion 10 when the fuser body 5 is not mounted. FIG. 16 is a perspective view showing a fusion splicing work table according to a modification of the present embodiment, which is a fusion splicing work table when the bracket unit 10 and the fusing machine body 5 shown in FIG. 14 are mounted. FIG. 17 is a perspective view showing the fusion splicing workbench shown in FIG. 16, which is a fusion splicing workbench when accommodated in a state where the bracket portion 10 is mounted when the fuser body 5 is not mounted. .

As shown in FIG. 14 and FIG. 15, the bracket portion 10 of the modified example separates the bottom surface portion 11 and the folded portion 12 and connects them via a spring hinge 16 in this embodiment. On the other hand, the folding | turning part 14 supports the rear surface of the melt | fusion machine main body 5 via the shock absorbing material 60, without using the screw 14a. Accordingly, as shown in FIG. 14, when the fuser body 5 is mounted (during use), the fuser body 5 is mounted on the bottom surface portion 11 while the rear surface of the fuser body 5 is hooked on the folded portion 14. The fuser main body 5 is fixed to the bracket portion 10 by generating a pressing force on the folded portion 12 using the force of the spring hinge 16.

On the other hand, as shown in FIG. 15, when the fuser body 5 is not mounted (accommodated), when the fuser body 5 is removed, the folded portion 12 is folded to the bottom surface portion 11 side by the force of the spring hinge 16. With such a configuration, the base portion 20 can be folded in two so that the bracket portion 10 is sandwiched between the mounting portion 21 and the support portion 22 with the bracket portion 10 attached. As a result, the entire fusion splicing work table can be accommodated in a compact manner.

At that time, the bracket portion 10 may be moved to a position where the folded portion 14 does not interfere with the support portion 22 of the base portion 20. In this way, by minimizing the folding structure, the number of parts can be reduced as much as possible to reduce the cost.

Further, as shown in FIGS. 16 and 17, the support portion 22 in the base portion 20 of the present embodiment has a folded portion 22 b that is folded back to the lateral edge, and the folded portion of the mounting portion 21 is formed by the folded portion 22 b. The base portion 20 may be folded in half so as to cover 21a.
