The present disclosure relates to a tray for fusion splicing work and a fusion splicer set. This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2020-174185 filed on Oct. 15, 2020, the entire contents of which are incorporated herein by reference.
Patent Literature 1 discloses an example of a work table for performing fusion splicing for an optical fiber. The work table includes a bracket portion for fixing a fusion splicer main body and a base portion. The base portion has a mounting portion on which the bracket portion is mounted and a support portion supported by an operator, and the mounting portion and the support portion form an L shape when fusion splicing is performed. Patent Literature 2 discloses another example of a work table. Patent Literature 3 discloses a housing case for a fusion splicer that also functions as a work table.
An aspect of the present disclosure provides a tray for fusion splicing work. This tray for fusion splicing work is a tray used for fusion splicing work for an optical fiber, and includes a tray main body and a first body contact member. The tray main body includes a pair of long wall portions opposing each other and extending along a first direction, and a pair of short wall portions opposing each other and extending along a second direction intersecting with the first direction. The tray main body is provided with a placement portion on which a fusion splicer is able to be placed within a rectangular region defined by the pair of long wall portions and the pair of short wall portions. The first body contact member includes an outer surface configured to come into contact with a body of an operator using the fusion splicer and is attached to the tray main body on a side of one long wall portion of the pair of long wall portions. The first body contact member is able to be transitioned between an unfolded state in which the outer surface is unfolded in a third direction intersecting with the first direction and the second direction, and a housed state in which the first body contact member is housed from the unfolded state.
Another aspect of the present disclosure provides a fusion splicer set. This fusion splicer set includes a housing case including the tray for fusion splicing work described above, and a fusion splicer placed on the placement portion of the tray. In this fusion splicer set, the tray for fusion splicing work is detachable from the housing case.
In a case where the tray is provided with a body contact member (corresponding to the support portion of Patent Literature 1) that comes into contact with the body of the operator using the fusion splicer, the stability of the tray during the fusion splicing work is improved. However, when the tray is housed in the housing case, the body contact member is bulky and may not be easily housed. Therefore, it is desired to develop a tray that can be easily housed in the housing case while maintaining the stability during the fusion splicing work.
An object of the present disclosure is to provide a tray for fusion splicing work that can be easily housed in a housing case while maintaining stability during fusion splicing work.
According to the aspect of the present disclosure, it is possible to provide a tray for fusion splicing work that can be easily housed in a housing case while maintaining stability during fusion splicing work.
First, contents of an embodiment of the present disclosure will be listed and described. A tray for fusion splicing work according to an embodiment of the present disclosure is a tray used for fusion splicing work for an optical fiber, and includes a tray main body and a first body contact member. The tray main body includes a pair of long wall portions opposing each other and extending along a first direction, and a pair of short wall portions opposing each other and extending along a second direction intersecting with the first direction. The tray main body is provided with a placement portion on which a fusion splicer is able to be placed within a rectangular region defined by the pair of long wall portions and the pair of short wall portions. The first body contact member includes an outer surface configured to come into contact with a body of an operator using the fusion splicer and is attached to the tray main body on a side of one long wall portion of the pair of long wall portions. The first body contact member is able to be transitioned between an unfolded state in which the outer surface is unfolded in a third direction intersecting with the first direction and the second direction, and a housed state in which the first body contact member is housed from the unfolded state.
In this tray for fusion splicing work, the first body contact member is provided, and this first body contact member can be transitioned between the unfolded state and the housed state. Therefore, when the fusion splicing work is performed, the work can be performed in a state in which the tray is stabilized by making the first body contact member be in the unfolded state. On the other hand, when the tray is housed, it is possible to easily house the tray in the housing case by making the first body contact member be in the housed state.
As an embodiment, the tray main body may include a first region in which the placement portion is provided and a second region on a side opposite to the first region in the tray main body in the third direction. The first body contact member may be connected to the tray main body with a hinge mechanism in the second region. In this embodiment, the first body contact member is located in the second region on a side opposite to the first region in which the placement portion for the fusion splicer is provided. Therefore, the first body contact member can be housed along the second region without coining into contact with the fusion splicer. As a result, when the first body contact member is housed, it is possible to place the fusion splicer as it is without detaching the fusion splicer from the tray or moving the fusion splicer from the placement portion.
As an embodiment, in the unfolded state, the first body contact member may include a main body portion that extends in the first direction along an edge portion of the one long wall portion of the tray main body to which the first body contact member is attached, and a pair of leg portions that extend in the third direction away from the tray main body with both ends of the main body portion in the first direction as base ends. According to this embodiment, when the first body contact member is made to be in the housed state, another member (for example, the second body contact member which will be described later) can be housed in the space between the pair of leg portions, thereby improving the housing efficiency.
As an embodiment, a length of each of the pair of leg portions may be greater than a length of the tray main body in the third direction. As the length of the leg portion increases, the outer surface of the first body contact member that comes into contact with the body of the operator using the fusion splicer can be enlarged. According to this present embodiment, a wide outer surface of the first body contact member can be secured, and the stability of the tray during work is improved.
As an embodiment, in the unfolded state, a width of the main body portion in the third direction may be one-half or less of a length of each of the pair of leg portions. According to this embodiment, a wide space can be secured between the pair of leg portions, and the housing efficiency can be further improved.
As an embodiment, the tray main body may include a connection portion to which a tripod that supports the tray is able to be connected. In the housed state, the connection portion may exist between the pair of leg portions when viewed in the third direction. According to this embodiment, the tripod can be connected to the connection portion of the tray main body without being hindered by the first body contact member even in a state where the first body contact member is housed.
As an embodiment, the outer surface of the first body contact member may include a curved surface portion protruding in a direction from the outside toward the inside of the tray main body. According to this embodiment, when the fusion splicing work is performed, the outer surface of the first body contact member fits the body of the operator, and the stability of the tray is improved.
As an embodiment, the tray for fusion splicing work may further include a second body contact member detachably attached to the tray main body on a side of the one long wall portion of the pair of long wall portions and on a side opposite to the first body contact member. According to this embodiment, the tray is provided with not only the first body contact member but also the second body contact member, thereby further improving the stability of the tray during the fusion splicing work. Further, since the second body contact member can be detached from the tray main body, the tray can be easily housed in the housing case.
As an embodiment, the tray main body may include a first attachment portion which is provided on one of the pair of long wall portions and to which a belt put around a waist of the operator is able to be attached, and a second attachment portion which is provided on both of the pair of short wall portions and to which a strap put around a neck of the operator is able to be attached. According to this embodiment, by attaching the belt to the tray main body, the tray main body is fixed, and the stability of the tray is improved during the fusion splicing work. Moreover, by putting the strap attached to the tray main body around the neck, the operator can carry out the work while keeping the tray close to the body without continuously holding the tray main body by hand. Therefore, the working efficiency of the fusion splicing work is improved.
As an embodiment, at least one wall portion of the pair of long wall portions and the pair of short wall portions may be provided with a notch depressed inside the tray main body. According to this embodiment, when the tray is housed in the housing case, the devices disposed in the spaces located on both sides of the tray can be cable-connected via the notches.
A fusion splicer set according to an embodiment of the present disclosure includes a housing case including the tray for fusion splicing work according to any one of the embodiments described above, and a fusion splicer placed on the placement portion of the tray. In this fusion splicer set, the tray for fusion splicing work is detachable from the housing case. According to this fusion splicer set, it is possible to obtain the same effect as each embodiment of the tray for fusion splicing work described above.
An embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings. The present invention is not limited to this example, but is defined by the scope of the claims, and is intended to include meanings equivalent to the scope of the claims and all modifications within the scope. In the following description, the same reference signs will be used for the same elements or elements having the same functions, and redundant description will be omitted.
A housing case 1 and a fusion splicer set 110 according to the embodiment will be described with reference to
First, the fusion splicer 100 housed in the housing case 1 will be described with reference to
The housing case 1 is a case for housing the fusion splicer 100 for an optical fiber. The housing case 1 includes the case main body 10, the lid body 30, and a tray 40. As illustrated in
The housing case 1 has a ring-shaped handle 3. The handle 3 is attached to a side of the case main body 10 opposite to a side on which the hinges 2 are located. An operator can easily carry the housing case 1 by gripping the handle 3. The handle 3 may be provided in the lid body 30. The housing case 1 has a pair of locking members 4. Each locking member 4 is constituted by a pair of metal fittings provided in the case main body 10 and the lid body 30. The lid body 30 is maintained in a closed state by engaging the pair of metal fittings with each other, and unintended opening and closing of the lid body 30 is prevented.
As illustrated in
As illustrated in
The first peripheral wall 12 is a wall-shaped member rising from the edge portion of the bottom plate 11. The first peripheral wall 12 includes a front side peripheral wall 12a provided with the handle 3, a rear side peripheral wall 12b located on a side opposite to the front side peripheral wall 12a and provided with the hinges 2, and a left side peripheral wall 12c and a right side peripheral wall 12d which connect the front side peripheral wall 12a and the rear side peripheral wall 12b to each other. The left side peripheral wall 12c is a wall-shaped member located on the left side of the case main body 10 when the case main body 10 is viewed from the front side peripheral wall 12a, and the right side peripheral wall 12d is a wall-shaped member located on the right side of the case main body 10 when the case main body 10 is viewed from the front side peripheral wall 12a. The widths of the front side peripheral wall 12a and the rear side peripheral wall 12b are slightly larger than the widths of the left side peripheral wall 12c and the right side peripheral wall 12d. Therefore, the overall shape of the case main body 10 is such that the width in a left-right direction is larger than the width in a front-rear direction. The shape of the case main body 10 is not limited and may be a shape having equal widths in the front-rear direction and in the left-right direction.
The bottom plate 11 and the first peripheral wall 12 may be formed of a resin such as polypropylene or polyethylene. The bottom plate 11 and the lower portion of the first peripheral wall 12 are constituted by stacking members formed of the same material or different materials and are thicker than the upper portion of the first peripheral wall 12. As a result, the fusion splicer 100 can be more reliably protected from impact applied to the lower portion of the housing case 1 when the housing case 1 is dropped. Moreover, due to the difference in thickness, a step surface 20 is provided at the boundary portion between the upper portion and the lower portion of the first peripheral wall 12. The step surface 20 is continuously provided along the inner circumference of the first peripheral wall 12. The edge portion of a tray 40 (see
The lid body 30 is a member that closes an opening of the case main body 10 and has a top plate 31 and a second peripheral wall 32 (a second side wall). The top plate 31 is a substantially rectangular plate-like member in a plan view and is located at the upper portion of the lid body 30. As illustrated in
The second peripheral wall 32 is a wall-shaped member rising from the edge portion of the top plate 31. The second peripheral wall 32 has a front side peripheral wall 32a, a rear side peripheral wall 32b, a left side peripheral wall 32c, and a right side peripheral wall 32d. In a state where the lid body 30 is closed, the front side peripheral wall 32a is a wall-shaped member located on the front side of the housing case 1, and the rear side peripheral wall 32b is a wall-shaped member located on the rear side of the housing case 1. Further, the left side peripheral wall 32c is a wall-shaped member located on the left side of the housing case 1, and the right side peripheral wall 32d is a wall-shaped member located on the right side of the housing case 1. The widths of the front side peripheral wall 32a, the rear side peripheral wall 32b, the left side peripheral wall 32c, and the right side peripheral wall 32d are designed to be approximately the same as the widths of the front side peripheral wall 12a, the rear side peripheral wall 12b, the left side peripheral wall 12c, and the right side peripheral wall 12d of the case main body 10, respectively.
The top plate 31 and the second peripheral wall 32 may be formed of a resin such as polypropylene or polyethylene. The top plate 31 and the second peripheral wall 32 are constituted by stacking members formed of the same material or different materials and are thicker than the upper portion of the first peripheral wall 12 of the case main body 10. As a result, the fusion splicer 100 housed inside the housing case 1 can be more reliably protected from external impact.
The top plate 31 or the second peripheral wall 32 has a window portion W made of a transparent member that transmits visible light. The window portion W may be formed by fitting a transparent resin member into an opening portion formed in the top plate 31 or the second peripheral wall 32, for example. The window portion W may be provided at a position at which a charging status of the fusion splicer 100 is able to be visually recognized. For example, in a case where a lamp indicating the charging status is provided in the right side surface of the fusion splicer 100, the window portion W may be provided in a portion of the top plate 31 near the right side peripheral wall 32d or in the right side peripheral wall 32d. In the present embodiment, the window portion W is provided in the right side peripheral wall 32d of the second peripheral wall 32. The window portion W may be provided in the first peripheral wall 12 of the case main body 10 instead of the lid body 30.
As illustrated in
As described above, the housing case 1 includes the insertion portion 5 (see
A detailed configuration of the notches 18 and 38 will be described with reference to
The first edge portion 13 has an end surface 14 (a first end surface) and a first thin wall 15, as illustrated in
The inner wall portion 17 is located closer to the inside of the case main body 10 than the non-depressed portion of the first thin wall 15. The inner wall portion 17 is provided along a facing direction of the pair of lateral wall portions 16, that is, along the extending direction of the first edge portion 13, and both end portions thereof are connected to the end portions of the lateral wall portions 16. The inner wall portion 17 has an upper surface 17a at its upper end. The notch 18 is provided in the central portion of the inner wall portion 17. The notch 18 is a portion through which the cable extending from the inside of the case main body 10 to the outside thereof is inserted. The notch 18 is formed in a U shape and has a gently curved bottom surface 18a. Further, a connecting portion between the end portion of the notch 18 and the upper surface 17a is smoothly connected as if a corner is removed. As a result, when the cable is disposed in the notch 18, even in a case where the cable comes into contact with the connecting portion, the coating of the cable is less likely to be damaged. The width of the notch 18 in the extending direction of the inner wall portion 17 gradually decreases from the upper surface 17a toward the end surface 14. The shape of the notch 18 is not limited to the shape described above and may be formed in a V shape with a sharp bottom portion, for example.
The height of a portion of the inner wall portion 17 close to the notch 18 (the distance from the end surface 14 to the upper surface 17a) is larger than that of each of both end portions of the inner wall portion 17 connected to the lateral wall portion 16. As a result, it is possible to prevent the cable inserted through the notch 18 from slipping out of the notch 18. In addition, the inner wall portion 17 is configured such that the thickness thereof decreases from the end surface 14 toward the upper surface 17a.
The sealing member 19 (a first sealing member) is disposed on the end surface 14 as illustrated in
The sealing member 19 is formed in a rectangular parallelepiped shape and disposed such that its longitudinal direction is along the extending direction of the first edge portion 13. The sealing member 19 has a pair of end surfaces 19a opposing each other in the longitudinal direction. In the present embodiment, each end surface 19a is located slightly apart from a wall surface of the lateral wall portion 16, and these gaps facilitate deformation of the sealing member 19 when the cable is sandwiched. Each end surface 19a may be in contact with the wall surface of the lateral wall portion 16 as long as it does not interfere with the holding of the cable by the sealing member 19. The sealing member 19 has four side surfaces connecting the pair of end surfaces 19a to each other. Of the four side surfaces, a surface (not illustrated) in contact with the end surface 14 is referred to as a lower side surface, and a surface opposing the lower side surface is referred to as an upper side surface 19b. Further, side surfaces connecting the lower side surface and the upper side surface 19b to each other are referred to as an outer side surface 19c and an inner side surface 19d. The outer side surface 19c and the inner side surface 19d are opposed to each other. The outer side surface 19c is located closer to the outside of the case main body 10 than the inner side surface 19d.
The lower side surface adheres to the end surface 14 by an adhesive. As a result, the sealing member 19 is fixed to the first edge portion 13. A fixing method of the sealing member 19 is not limited. For example, in a case where the end surface 14 has a protrusion, the sealing member 19 may be fixed by inserting the protrusion into the lower side surface. The upper side surface 19b is located further apart from the end surface 14 than the upper surface 16a. That is, the thickness of the sealing member 19 (the width from the lower side surface to the upper side surface 19b) is greater than the height of the lateral wall portion 16. Further, the upper side surface 19b is located further apart from the end surface 14 than the bottom surface 18a (see
The outer side surface 19c is located closer to the outside of the case main body 10 than the wall surface of the non-depressed portion of the first thin wall 15. However, the outer side surface 19c may be located closer to the inside of the case main body 10 than the wall surface of the non-depressed portion of the first thin wall 15, that is, may be located at the depression portion 15A of the first thin wall 15. The inner side surface 19d is located slightly apart from the wall surface of the inner wall portion 17. However, the inner side surface 19d may be located to be in contact with the wall surface of the inner wall portion 17. The shape of the sealing member 19 is not limited to the shape described above. The sealing member 19 may have, for example, a cuboid shape. Further, the upper side surface 19b of the sealing member 19 may be provided with a groove portion extending along a direction connecting the outer side surface 19c and the inner side surface 19d to each other, and the cable may be disposed in the groove portion.
The second edge portion 33 has an end surface 34 (a second end surface) and a second thin wall 35, as illustrated in
The notch 38 is provided in a portion of the outer wall portion 37 corresponding to a region where the pair of lateral wall portions 36 face each other (a portion of the outer wall portion 37 located between the pair of lateral wall portions 36). The notch 38 is a portion through which the cable extending from the inside of the case main body 10 to the outside thereof is inserted. The notch 38 is formed in a U shape and has a gently curved bottom surface 38a. Further, a connecting portion between the end portion of the notch 38 and the upper surface 35a is smoothly connected as if a corner is removed. As a result, when the cable is disposed in the notch 38, even in a case where the cable comes into contact with the connecting portion, the coating of the cable is less likely to be damaged. The width of the notch 38 in the extending direction of the second edge portion 33 gradually decreases from the upper surface 35a toward the end surface 34. The shape of the notch 38 is not limited to the shape described above and may be formed in a V shape with a sharp bottom portion, for example.
The sealing member 39 (a second sealing member) is disposed on the end surface 34 as illustrated in
The sealing member 39 is formed in a rectangular parallelepiped shape and disposed such that its longitudinal direction is along the extending direction of the second edge portion 33. The sealing member 39 has a pair of end surfaces 39a opposing each other in the longitudinal direction. In the present embodiment, each end surface 39a is slightly apart from the wall surface of the lateral wall portion 36, but may be in contact with the wall surface of the lateral wall portion 36. The sealing member 39 has four side surfaces connecting the pair of end surfaces 39a to each other. Of the four side surfaces, a surface (not illustrated) in contact with the end surface 34 (see
The lower side surface of the sealing member 39 adheres to the end surface 34 by an adhesive. As a result, the sealing member 39 is fixed to the second edge portion 33. A fixing method of the sealing member 39 is not limited. For example, in a case where the end surface 34 has a protrusion, the sealing member 39 may be fixed by inserting the protrusion into the lower side surface. The upper side surface 39b is located further apart from the end surface 34 than the upper surface 36a. That is, the thickness of the sealing member 39 (the width from the lower side surface to the upper side surface 39b) is greater than the height of the lateral wall portion 36. Further, the upper side surface 39b is located further apart from the end surface 34 than the bottom surface 38a of the notch 38. That is, at least a part of the sealing member 39 overlaps the notch 38 when the sealing member 39 is viewed from the inner side surface 39d. When the cable is inserted through the notch 38, the cable is disposed to sink slightly into the interior of the sealing member 39.
The outer side surface 39c is located slightly apart from the wall surface of the second thin wall 35 facing it. However, the outer side surface 39c may be located to be in contact with the wall surface. The inner side surface 39d is located closer to the inside of the lid body 30 than the end portion of each lateral wall portion 36. However, the inner side surface 39d may be located closer to the outside of the lid body 30 than the end portion of each lateral wall portion 36, that is, may be located within a region sandwiched between the pair of lateral wall portions 36. The shape of the sealing member 39 is not limited to the shape described above. The sealing member 39 may have, for example, a cuboid shape. Further, the upper side surface 39b of the sealing member 39 may be provided with a groove portion extending along a direction connecting the outer side surface 39c and the inner side surface 39d to each other, and the cable may be disposed in the groove portion.
The cable C is sandwiched between the sealing member 19 and the sealing member 39. The sealing member 19 and the sealing member 39 are formed of a resilient material as described above. Therefore, the sealing member 19 and the sealing member 39 are deformed according to the shape of the cable C and come into close contact with the coating of the cable C. The cable C extends from the inside of the housing case 1 to the outside of the housing case 1 through the notch 18, the portion between the sealing member 19 and the sealing member 39, and the notch 38. The cable C may be a power supply cable used to supply power to the fusion splicer 100 as described above, or may be a power supply cable used to supply power to an information terminal (such as a smart phone, for example) for managing fusion work in the fusion splicer 100. Two or more cables C may be sandwiched between the sealing member 19 and the sealing member 39.
A configuration of the tray 40 will be described with reference to
The tray main body 41 is a work table that houses the fusion splicer 100 and the like in order in the housing case 1 and is used for the fusion splicing work for the optical fibers. The operator positions the tray main body 41 in front of his/her body (for example, abdomen) and performs the fusion splicing work on the tray main body 41. A pair of long wall portions 42 and a pair of short wall portions 43 are provided in the outer peripheral edge portion of the tray main body 41. The pair of long wall portions 42 are wall-shaped members opposing each other and extending along a left-right direction (a first direction) of the tray 40. The pair of short wall portions 43 are wall-shaped members opposing each other and extending along a front-rear direction (a second direction) of the tray 40. The upper side end portions of the pair of long wall portions 42 and the pair of short wall portions 43 slightly protrude upward from the edge portion of the first region 50, which will be described later. This prevents tools and the like placed in the first region 50 and used for the fusion splicing work from falling out of the tray main body 41. Of the pair of long wall portions 42, the long wall portion 42 located on the front side of the tray 40 is referred to as a front side long wall portion 42a (one long wall portion), and the long wall portion 42 located on the rear side of the tray 40 is referred to as a rear side long wall portion 42b. Further, of the pair of short wall portions 43, the short wall portion 43 located on the left side of the tray 40 is referred to as a left side short wall portion 43a, and the short wall portion 43 located on the right side of the tray 40 is referred to as a right side short wall portion 43b.
The front side long wall portion 42a is a portion that comes into contact with the body of the operator during the fusion splicing work. The surface of the front side long wall portion 42a has a gently curved surface shape that is slightly protruded from the outer side (the front side) toward the inner side (the rear side) of the tray main body 41. As a result, the front side long wall portion 42a fits the body of the operator, and the stability of the tray 40 is improved. The front side long wall portion 42a has a pair of first attachment portions 44 to which a belt put around the waist of the operator is attached. Each first attachment portion 44 is provided at each of the left and right end portions of the front side long wall portion 42a. Each first attachment portion 44 is formed in an annular shape, and a belt can be inserted therein. The operator can pass the belt put around his/her waist through each first attachment portion 44 and perform the fusion splicing work in a state where the tray 40 is fixed.
The left side short wall portion 43a and the right side short wall portion 43b each have a second attachment portion 45 to which a strap put around the neck of the operator is attached. The second attachment portion 45 is provided at substantially the center portion of each of the left side short wall portion 43a and the right side short wall portion 43b in the front-rear direction of the tray 40. Each second attachment portion 45 is constituted by two holes penetrating the tray 40 in the left-right direction. When performing the fusion splicing work, the operator first attaches the strap to the tray main body 41 by passing hooks (for example, carabiners) provided at both ends of the strap through two holes. After that, the operator can carry out the fusion splicing work by putting the strap around the neck without continuously holding the tray main body 41.
Notches 46 and 47 depressed inside the tray main body 41 are provided in the right side portion of the rear side long wall portion 42b and the front side portion of the right side short wall portion 43b. Each of the notches 46 and 47 constitutes a tray notch. These notches 46 and 47 serve to connect the space above the tray 40 and the space below the tray 40 to each other when the tray 40 is housed in the case main body 10. Here, an aspect in which the tray 40 is housed will be described with reference to
As illustrated in
The notches 46 and 47 serve to connect the upper side housing space S1 and the lower side housing space S2 described above to each other. For example, when the power is supplied to the fusion splicer 100 using the power supply cable having an AC adapter in the middle thereof, the AC adapter is housed in the lower side housing space S2. In this case, a portion of the power supply cable which extends from the AC adapter to the fusion splicer 100 is pulled out from the lower side housing space S2 to the upper side housing space S1 through the notch 46. On the other hand, a portion of the power supply cable which extends from the AC adapter to the external power supply is pulled out from the lower side housing space S2 to the upper side housing space S1 through the notch 47. The portion of the power supply cable which is pulled out through the notch 47 to the upper side housing space S1 may be pulled out to the outside of the housing case 1 through the insertion portion 5 (the notches 18 and 38) of the housing case 1.
The tray main body 41 has the first region 50 and the second region 60 defined (surrounded) by the pair of long wall portions 42 and the pair of short wall portions 43, as illustrated in
The first region 50 is a substantially rectangular region in a plan view, as illustrated in
A front restricting portion 52, a pair of side restricting portions 53, and a rear restricting portion 54 are provided around the placement portion 51 to restrict movement of the fusion splicer 100 placed on the placement portion 51. The front restricting portion 52 is a wall-shaped member rising upward from the first region 50 and is provided to surround a front side corner portion of the placement portion 51. Each side restricting portion 53 is an arch-shaped member having two columns aligned in the front-rear direction of the tray 40 and a rod-shaped connecting portion that extends in the front-rear direction and connects the upper side end portions of the two columns to each other. The pair of side restricting portions 53 are provided such that the placement portion 51 is sandwiched therebetween in the left-right direction of the tray 40. The rear restricting portion 54 is a plate member that connects the rear side end portions of the pair of side restricting portions 53. The first region 50 is provided with a plurality of housing recesses 55 depressed inside the tray main body 41.

A detailed configuration of the first body contact member 70 and the second body contact member 80 will be described with reference to
The first body contact member 70 is a member that comes into contact with the body of the operator during the fusion splicing work. The first body contact member 70 has a pair of shaft portions 71, a pair of connecting portions 72, a main body portion 73, and a pair of leg portions 74, as illustrated in
The pair of connecting portions 72 are members that connect the pair of shaft portions 71 and the main body portion 73 to each other, as illustrated in
As illustrated in
The length Z of each leg portion 74 is greater than the length (the thickness) X in the vertical direction of the tray main body 41, as illustrated in
As illustrated in
As illustrated in
The second body contact member 80 is a member that comes into contact with the body of the operator during the fusion splicing work. As illustrated in
The pair of insertion portions 83 are portions protruding from the lower side end portion of the plate portion 81 toward the outside of the plate portion 81. Each insertion portion 83 is inserted into the insertion recess 56 of the first region 50 illustrated in
The pair of protrusions 84a are provided on the upper portions of a pair of lateral side surfaces 84 that are opposed to each other with the outer surface 82 interposed therebetween. As described above, when the second body contact member 80 is housed in the space between the pair of leg portions 74 (see
As described above, in the tray 40 for fusion splicing work according to the present embodiment, the first body contact member 70 is provided, and the first body contact member 70 can be transitioned between the unfolded state and the housed state. Therefore, when the fusion splicing work is performed, the work can be performed in a state in which the tray 40 is stabilized by making the first body contact member 70 be in the unfolded state. On the other hand, when the tray 40 is housed, it is possible to easily house the tray 40 in the housing case 1 by making the first body contact member 70 be in the housed state.
In the present embodiment, the tray main body 41 has the first region 50 in which the placement portion 51 is provided and the second region 60 on a side opposite to the first region 50 in the tray main body 41 in the third direction. The first body contact member 70 is connected to the tray main body 41 with the hinge mechanism in the second region 60. In this case, the first body contact member 70 is located in the second region 60 on a side opposite to the first region 50 in which the placement portion 51 for the fusion splicer 100 is provided. Therefore, the first body contact member 70 can be housed along the second region 60 without coining into contact with the fusion splicer 100. As a result, when the first body contact member 70 is housed, it is possible to place the fusion splicer 100 as it is without detaching the fusion splicer 100 from the tray 40 or moving the fusion splicer 100 from the placement portion 51.
In the present embodiment, in the unfolded state, the first body contact member 70 has the main body portion 73 that extends in the first direction along the edge portion of the one long wall portion 42 (the front side long wall portion 42a) of the tray main body 41 to which the first body contact member 70 is attached, and the pair of leg portions 74 that extend in the third direction away from the tray main body 41 with both ends of the main body portion 73 in the first direction as base ends. In this case, when the first body contact member 70 is made to be in the housed state, another member (for example, the second body contact member 80) can be housed in the space between the pair of leg portions 74, thereby improving the housing efficiency.
In the present embodiment, the length Z of each of the pair of leg portions 74 is greater than the length X of the tray main body 41 in the third direction. As the length of the leg portion 74 increases, the outer surface 75 of the first body contact member 70 that comes into contact with the body of the operator using the fusion splicer 100 can be enlarged. Therefore, according to the present embodiment, a wide outer surface 75 of the first body contact member 70 can be secured, and the stability of the tray 40 during work is improved.
In the present embodiment, in the unfolded state, the width Y of the main body portion 73 in the third direction may be one-half or less of the length of each of the pair of leg portions 74. In this case, a wide space can be secured between the pair of leg portions 74, and the housing efficiency can be further improved.
In the present embodiment, the tray main body 41 has the connection portion E to which the tripod that supports the tray 40 is able to be connected. In the housed state, the connection portion E exists between the pair of leg portions 74 when viewed in the third direction. In this case, the tripod can be connected to the connection portion E of the tray main body 41 without being hindered by the first body contact member 70 even in a state where the first body contact member 70 is housed.
In the present embodiment, the outer surface 75 of the first body contact member 70 includes the curved surface portion protruding in a direction from the outside toward the inside of the tray main body 41. In this case, when the fusion splicing work is performed, the outer surface 75 of the first body contact member 70 fits the body of the operator, and the stability of the tray 40 is improved.
In the present embodiment, the second body contact member 80 detachably attached to the tray main body 41 on a side of the one long wall portion of the pair of long wall portions 42 and on a side opposite to the first body contact member 70 is further provided. In this case, the tray 40 is provided with not only the first body contact member 70 but also the second body contact member 80, thereby further improving the stability of the tray 40 during the fusion splicing work. Further, since the second body contact member 80 can be detached from the tray main body 41, the tray 40 can be easily housed in the housing case 1.
In the present embodiment, the tray main body 41 has the first attachment portion 44 which is provided on one of the pair of long wall portions 42 and to which the belt put around the waist of the operator is able to be attached, and the second attachment portion 45 which is provided on both of the pair of short wall portions 43 and to which the strap put around the neck of the operator is able to be attached. In this case, by attaching the belt to the tray main body 41, the tray main body 41 is fixed, and the stability of the tray 40 is improved during the fusion splicing work. Moreover, by putting the strap attached to the tray main body 41 around the neck, the operator can carry out the work while keeping the tray 40 close to the body without continuously holding the tray main body 41 by hand. Therefore, the working efficiency of the fusion splicing work is improved.
In the present embodiment, at least one wall portion of the pair of long wall portions 42 and the pair of short wall portions 43 is provided with the notch 46 or 47 depressed inside the tray main body 41. In this case, when the tray 40 is housed in the housing case 1, the devices disposed in the spaces (the upper side housing space S1 and the lower side housing space S2) located on both sides of the tray 40 can be cable-connected through the notches 46 and 47.
Although the embodiment according to the present disclosure is described in detail above, the present invention is not limited to the above embodiment and can be applied to various embodiments.
The insertion portion 5 through which the cable is inserted may be a through hole provided in the first peripheral wall 12 of the case main body 10 or the second peripheral wall 32 of the lid body 30 instead of the notches 18 and 38. In this case, a through hole may be provided in the bottom plate 11 of the case main body 10 or the top plate 31 of the lid body 30.
The first body contact member 70 may be attachable to and detachable from the tray main body 41 similarly to the second body contact member 80. In this case, the state in which the first body contact member 70 is detached from the tray main body 41 corresponds to the housed state of the first body contact member 70. Further, the first body contact member 70 may have a rectangular plate shape in a plan view similarly to the second body contact member 80.
The second body contact member 80 may be able to be housed such that the second body contact member 80 is connected to the tray main body 41 with a hinge mechanism and is folded to a side of the first region 50 of the tray main body 41 similarly to the first body contact member 70. In this case, the second body contact member 80 may have a U shape (the shape similar to the first body contact member 70) with a hollow central portion not to come into contact with the fusion splicer 100 or the like in the housed state.
The first body contact member 70 and the second body contact member 80 may have handles that can be gripped by the operator to facilitate the transition between the unfolded state and the housed state.
