Description

[Technical Field]

[0001] The present invention relates to an outdoor work set. [Background technology]

[0002] Currently, amid the COVID-19 pandemic, teleworking is being promoted, and many business people are working from home. However, working at home for long periods of time can lead to boredom and a tendency to stay cooped up at home, which is not good for mental health. Therefore, by occasionally going outside and doing work-related tasks in an open outdoor environment, you can have a change of mood and expect to improve your work efficiency.

[0003] Patent Document 1 discloses a backpack that is designed for use when watching sports outdoors, with a storage compartment formed on the outside of the part that becomes a seat when unfolded. Patent Document 2 discloses a backpack similar to Patent Document 1 that is designed for use when traveling or for emergency transport of emergency patients. Patent Document 3 discloses a seat chair that becomes a seat when unfolded, designed for use when mountain climbing or camping. Patent Document 4 discloses a backpack that becomes a mat when unfolded, designed for use in the event of a disaster such as an earthquake or fire. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 7-18626 [Patent Document 2] Korean Patent Publication No. 2011-0002433 [Patent Document 3] Japanese Patent Application Publication No. 9-103340 [Patent Document 4] Utility Model Registration No. 3198792 Summary of the Invention [Problem to be solved by the invention]

[0005] The backpacks and floor chairs in Patent Documents 1 to 4 are not intended for use by users when casually performing work-related tasks outdoors. Specifically, the backpacks disclosed in Patent Documents 1 and 2 have a storage compartment for storing luggage on the outside of the floor chair portion. This makes the backpack larger overall, and the backpack's structure more complex, which inevitably increases its weight.

[0006] Furthermore, the chairs and backpacks described in Patent Documents 3 and 4 do not have a storage compartment, so users must carry their work belongings in a separate bag, etc. In this way, to eliminate as many barriers as possible to users working outdoors, there is a need for a simple, lightweight structure with efficient storage functionality and comfort that does not interfere with work.

[0007] The present invention has been made in view of such problems, and aims to provide a portable outdoor work set that is compact, has a simple and lightweight structure, realizes efficient storage, and allows work-related tasks to be easily and comfortably performed outdoors whenever the desire arises. [Means for solving the problem]

[0008] In order to achieve the above object, the outdoor work set of the present invention is a portable type that can be used for work outdoors, and includes a foldable sheet to be placed at the work site, a foldable shade that provides shade to the worker, and a backpack that can be carried by the worker on the back and has a storage space in which the folded sheet and shade can be stored. The storage space is divided by a storage section that contacts the back of the worker and a lid that covers the storage section from the outside, and the backpack can be used by placing it on the sheet and by the worker by unfolding the lid over the storage section. In the open storage space It is like sitting on a chair with your back leaning back. The shade has a core material on its outer edge and can be moved between a folded state and an unfolded state by bending the core material. When the shade is in the unfolded state in the chair position, it forms a sunshade above the seat and backpack. When the worker sits in the chair position, the shade and the seat are attached at their rear ends located at the rear in the longitudinal direction of the shade and the seat, and their front ends located at the front in the longitudinal direction of the shade and the seat are connected by a second adjustable string that can be stretched and contracted. [Effects of the Invention]

[0009] The outdoor work set of the present invention is compact, has a simple and lightweight structure, and allows for efficient storage, allowing you to easily and comfortably carry out work-related tasks outdoors whenever you feel like it.This makes it possible to quickly create the environment necessary for work outdoors, and by adding the outdoors to your work style options, it can contribute to promoting work style reform.

DETAILED DESCRIPTION OF THE INVENTION

[0011] First Embodiment FIG. 1 shows a perspective view of an example of an outdoor work set (hereinafter simply referred to as the set) according to a first embodiment of the present invention in use. Set 1 is a portable set that can be used for outdoor work, and is composed of a seat 2, a shade 4, a desk 6, and a backpack 8. By unfolding or assembling the components of set 1, a worker can carry out work such as computer work outdoors on the grass.

[0012] The seat 2 is placed at an outdoor work location for use and is foldable. The shade 4 is detachably attached to the seat 2, provides a sunshade 10 for the seated worker, and is foldable. The desk 6 is placed on the seat 2 for use and is foldable. The backpack 8 can be carried by the worker on their back and becomes a seat chair 12 when unfolded.

[0013] When in the state of the seat 12, the backpack 8 is composed of a seat 14 and a backrest 16, and is placed on the seat 2 for use, and a worker can sit with their back against it. The backrest 16 and the shade 4 are connected and held together by a retaining string 18. Both ends of the retaining string 18 are respectively connected near the center in the height direction of both sides of the shade 4. A buckle 20 with an adjuster function is attached to the retaining string 18, and the retaining string 18 separated at the buckle 20 is passed through a loop-shaped handle 22 formed at the top of the backrest 16, and the backrest 16 and the shade 4 are held together by connecting the buckle 20.

[0014] FIG. 2 shows a worker wearing backpack 8. Backpack 8 is made of a lightweight material that is waterproof, strong, flexible, and made of synthetic fibers such as nylon or polyester. The holding straps 18 are also made of the same material. Inside backpack 8, a storage space 24 is formed in which the folded seat 2, shade 4, and desk 6 are stored. Storage space 24 is defined by a storage section 26 that comes into contact with the worker's back and a lid 28 that covers storage section 26 from the outside.

[0015] When the storage section 26 is in the state of the backpack 8, upper surface part 38, The backpack 8 is configured with a bottom portion 30, opposing side portions 32, and a back portion 34. The lid portion 28 is connected to the outer surface portion 3 6 or The outer surface portion 36 is configured to define the storage space 24 together with the storage portion 26. The outer surface portion 36 is flexibly connected to the bottom surface portion 30 and faces the back surface portion 34. The top surface portion 38 is flexibly connected to the outer surface portion 36 and faces the bottom surface portion 30. The outer surface portion 36 is provided with an outer surface storage portion 40 that can be opened and closed by a zipper (registered trademark) or the like. Pockets for storing small items may be provided on both side surfaces 32.

[0016] 3 shows a perspective view of backpack 8 in the state of floor chair 12. An opening / closing section 42 such as a zipper (registered trademark) is formed at the boundary between storage section 26 and lid section 28 of backpack 8, and by opening opening / closing section 42, lid section 28 is unfolded relative to storage section 26, thereby transforming backpack 8 into floor chair 12. When backpack 8 is in the state of floor chair 12, bottom surface 30 and outer surface 36 of backpack 8 become seat 14 of floor chair 12 that supports the lower body of a seated worker, and back surface 34 and top surface 38 of backpack 8 become backrest 16 of floor chair 12 that supports the back of the seated worker. Back surface 34 is provided with a pocket 43 that can store documents, etc.

[0017] When the backpack 8 is in the state of the seat chair 12, the pair of side sections 32 serve as side covers 44 of the seat chair 12, respectively covering the left and right sides of the upper body of the seated worker. A lightweight core material 46 in the form of a thin rod made of resin or metal is provided near the boundary between the backrest 16 of the seat chair 12 or the side cover 44. Similar core materials 48 are also provided on both sides of the seat 14 of the seat chair 12, i.e., on both sides of the outer surface section 36 of the backpack 8.

[0018] Each core material 46, 48 increases the rigidity of the backrest 16 and seat portion 14 when in the state of the seat chair 12, and increases the rigidity of the back surface portion 34 and outer surface portion 36 when in the state of the backpack 8. Each core material 46, 48 defines the storage space 24 without collapsing when in the state of the backpack 8. When in the state of the seat chair 12, the backpack 8 has a first stretchable adjustment string 50 that connects the backrest 16 or the side cover 44 to the seat portion 14.

[0019] The first adjustment cords 50 are made of the same material as the backpack 8, and two are provided in pairs in an inclined arrangement so as not to obstruct the space for the worker to sit in when the chair 12 is in the state of being seated. One end of each first adjustment cord 50 is attached to the upper part of the boundary between the backrest 16 and each side cover 44, and the other end of each first adjustment cord 50 is attached to each of both side parts of the seat portion 14.

[0020] That is, each first adjustment cord 50 essentially connects each core material 46 and each core material 48 described above. As a result, when a worker leans their back against the backrest 16, the load acting on the backrest 16 is distributed to the seat 14 via each core material 46, each first adjustment cord 50, and each core material 48. Because the seat 14 is pressed down onto the ground (workplace) by the weight of the seated worker, the legless chair 12 is prevented from tipping over when the worker leans their back against the backrest 16.

[0021] An adjuster 52 is attached to each first adjustment cord 50. By operating each adjuster 52, each first adjustment cord 50 expands or contracts, adjusting the angle of the backrest 16 relative to the seat 14, i.e., the reclining angle of the legless chair 12. It is preferable that one end of each first adjustment cord 50 is attached to the boundary between the backrest 16 and the pair of side covers 44, but it may also be attached to the backrest 16 or the side cover 44.

[0022] 4 shows a plan view of the sheet 2 and the shade 4. The sheet 2 and the shade 4 are made of a lightweight material that is waterproof, strong, flexible, etc., such as nylon, vinyl, or polyester, and can be easily attached to and detached from each other using a detachable part 54 such as Velcro (registered trademark). A thin rod-shaped, lightweight core material 56 made of resin or metal, which is flexible and resilient, is provided inside the outer edge of the shade 4 excluding the detachable part 54.

[0023] More specifically, the seat 2 has a front end 2a located on the front side in the longitudinal direction X and a rear end 2b located on the rear side when in the state of the seat 12. The shade 4 has a front end 4a located on the front side in the longitudinal direction X, a rear end 4b located on the rear side when in the state of the seat 12, and an intermediate portion 4c located between the front end 4a and the rear end 4b. A detachable portion 54 is provided at the rear end 4b of the shade 4 when in the state of the seat, and the rear end 2b of the seat 2 is detachably attached to it. In addition, a holding string 18 connects and holds the intermediate portion 4c of the shade 4 and the backrest 16 of the seat 12 via a handle 22.

[0024] Figure 5 shows the folded state of the shade 4. The shade 4 is folded into a compact circular shape as shown in Figure 5 when an operator bends the core material 56 against its elastic force. When the operator applies a small amount of force from the folded state, the elastic force of the core material 56 causes the shade 4 to automatically unfold into the state shown in Figure 4. In other words, the shade 4 has a structure similar to that of a one-touch tent or a pop-up tent.

[0025] The shade 4 is provided with an expandable second adjustment cord 58 that connects the front end 2a of the seat 2 and the front end 4a of the shade 4 when the seat is in the state of the floor chair 12. The second adjustment cord 58 is made of the same material as the first adjustment cord 50, and two second adjustment cords 58 are provided in pairs in an inclined position so as not to obstruct the seating space of the worker when the seat is in the state of the floor chair 12. The pair of second adjustment cords 58 are attached to the sides of the front end 4a of the shade 4 and connected to the sides of the front end 2a of the seat 2.

[0026] A buckle 60 with an adjuster function is attached to each second adjustment cord 58. The seat 2 and shade 4 can be separated by separating each second adjustment cord 58 at the buckle 60 and removing the detachable part 54. By operating the adjuster of the buckle 60, each second adjustment cord 58 can be lengthened or shortened, thereby adjusting the curved angle of the upper part of the shade 4 relative to the seat 2 and the seat part 14 of the legless chair 12. When the seat is in the legless chair position, by shortening the length of each second adjustment cord 58, a curved region 62 that functions as the sunshade part 10 is formed in the upper part of the shade 4.

[0027] Each second adjustment cord 58 essentially connects each core material 56 of the shade 4 to both side portions of the seat 2. Because the seat 2 is pressed against the ground via the seat portion 14 of the legless chair 12 by the weight of the seated worker, when the length of each second adjustment cord 58 is adjusted to be shorter using the adjuster of the buckle 60, tension is generated in each second adjustment cord 58, and a curved region 62, i.e., a sunshade portion 10, is formed in the shade 4.

[0028] FIG. 6 shows a perspective view of the desk 6. The desk 6 is composed of a top panel 64, a pair of legs 66, and a work table 68. Each leg 66 is plate-shaped and is provided at a height and distance that allows a seated worker's legs to be tucked under the top panel 64, supporting both sides of the top panel 64. The work table 68 has a mounting surface 70 on which a personal computer or documents can be placed at an angle, and is fixed to the top panel 64. The top panel 64, each leg 66, and the work table 68 are each formed from separate, rigid, and lightweight resin sheets 72, 74. The desk 6 is formed by folding and assembling the resin sheets 72, 74.

[0029] 7(a) shows a developed view of a resin sheet 72 that will become the workbench 68, and (b) shows a developed view of a resin sheet 74 that will become the top plate 64 and each leg 66. In FIGS. 7(a) and 7(b), the left-right direction is the longitudinal direction of each resin sheet 72, 74, and the up-down direction is the width direction of each resin sheet 72, 74. As shown in FIG. 7(a), a first fold line 76 that reduces the thickness of the resin sheet 72 is formed across the entire width at the longitudinal center of the resin sheet 72 that will become the workbench 68, and the resin sheet 72 can be folded at the first fold line 76.

[0030] A support portion 78 of the workbench 68 is formed on one side of the first fold line 76 of the resin sheet 72, i.e., on the right side as viewed in Figure 7(a), and a placing portion 80 having the placing surface 70 of the workbench 68 is formed on the other side, i.e., on the left side as viewed in Figure 7(a). A second fold line 82 that reduces the thickness of the resin sheet 72 is formed in the center of the support portion 78 in the longitudinal direction across the entire width, and the resin sheet 72 can be folded at the second fold line 82.

[0031] First locking claws 84 are cut out at two locations along the second fold line 82 of the support portion 78. A second locking claw 86 is cut out across part of the width direction at a position closer to the first fold line 76 than the longitudinal center of the placing portion 80. A third locking claw 88 similar to the second locking claw 86 is cut out at a position close to the longitudinal edge of the placing portion 80.

[0032] The second and third locking claws 86 and 88 have a reduced thickness at the boundary (indicated by the dashed line) with the resin sheet 72, allowing them to be easily folded up toward the mounting surface 70. In addition, two fourth locking claws 90 are formed on the longitudinal edge of the mounting portion 80 so as to protrude outward in the longitudinal direction. The procedure for assembling the resin sheet 72 to the workbench 68 will be described below.

[0033] First, the first fold line 76 is folded toward the back side of the resin sheet 72, opposite the placement surface 70, and the second fold line 82 is similarly folded toward the back side. Next, the second locking claw 86 is folded toward the back side, and the edge of the support portion 78 is locked to the folded second locking claw 86. This forms the support portion 78 of the workbench 68. Furthermore, by folding the third locking claw 88 toward the placement surface 70, the third locking claw 88 functions as an anti-slip device for a computer, documents, etc. placed on the placement surface 70. This forms the placement portion 80 of the workbench 68.

[0034] 7(b), a third fold line 92 that reduces the thickness of the resin sheet 74 is formed across the entire width in the center of the longitudinal direction of the resin sheet 74 that forms the top plate 64 and each leg 66, and the resin sheet 74 can be folded at the third fold line 92. When the third fold line 92 is taken as the boundary, a fourth fold line 94 and a fifth fold line 96 that reduce the thickness of the resin sheet 74 are each formed across the entire width in the center of the longitudinal direction of the resin sheets 74 on both sides.

[0035] This allows the resin sheet 74 to be folded at the fourth fold line 94 and the fifth fold line 96, and by folding the resin sheet 74 at 90 degrees at the fourth fold line 94 and the fifth fold line 96, plate-shaped legs 66 are formed at positions that sandwich the top plate 64. The resin sheet 74 has a portion that forms a top surface portion 98 of the top plate 64. At both ends in the width direction of the resin sheet 74, a sixth fold line 100 and a seventh fold line 102 that reduce the thickness of the resin sheet 74 are formed over the entire longitudinal direction at positions that are small enough to ensure the area of ​​the top surface portion 98 from the end edges.

[0036] This allows the resin sheet 74 to be folded at 90° along the sixth fold line 100 and the seventh fold line 102. These folded portions form reinforcing portions 104 of the top panel 64 and each leg 66. Cuts 106 are made in the ranges from both widthwise edges of the fourth fold line 94 to the sixth fold line 100 and the seventh fold line 102, respectively, in other words, in the ranges where the reinforcing portions 104 are formed. Similar cuts 108 are also made in the range of the fifth fold line 96 where the reinforcing portion 104 is formed.

[0037] Snap buttons 110 are attached to both longitudinal sides of each of the notches 106, 108 of the reinforcing portion 104. Each snap button 110 is made up of a pair of stud and cap. When the desk 6 is assembled, the reinforcing function of the reinforcing portion 104 is provided to the top panel 64 and each leg 66 by fitting these studs and caps together.

[0038] A pair of locking holes 112 are formed at both widthwise ends of the region of the resin sheet 74 that will become the top panel 64, at positions that sandwich the third fold line 92. Each pair of locking holes 112 is formed in a position that follows the sixth fold line 100 and the seventh fold line 102, respectively. Finger holes 114 are formed in each region of the resin sheet 74 that will become the legs 66, allowing fingers to be inserted when moving the assembled desk 6.

[0039] The procedure for assembling the resin sheet 74 to the tabletop 64 and each leg 66 will be described below. First, the resin sheet is folded 90 degrees along the sixth fold line 100 and the seventh fold line 102, and then further folded 90 degrees along the fourth fold line 94 and the fifth fold line 96. Next, the caps and studs of each snap button 110, which are positioned so as to overlap, are fitted together. This allows the tabletop 64 and each leg 66 to be assembled while being reinforced by the reinforcing portions 104.

[0040] Then, the first locking claws 84 and the fourth locking claws 90 of the assembled work table 68 are fitted into and locked into the locking holes 112 of the top plate 64, thereby fixing the work table 68 to the top plate 64. This completes the assembly of the desk 6. The work table 68 can be easily removed from the top plate 64 by pulling out the first locking claws 84 and the fourth locking claws 90 of the work table 68 from the locking holes 112 of the top plate 64.

[0041] 8 shows the folded state of the desk 6. To fold the desk 6, first, the first locking claws 84 and the fourth locking claws 90 of the work table 68 are pulled out of the locking holes 112 of the top panel 64, the work table 68 is removed from the top panel 64, and the desk 68 is returned to the state of the resin sheet 72. Then, the resin sheet 72 is folded at the first and second fold lines 76, 82.

[0042] Next, the snap buttons 110 are released to return the top panel 64 and the legs 66 to the state of the resin sheet 74, and the resin sheet 74 is folded along the third to fifth fold lines 92, 94, and 96. The resin sheets 72 and 74 are then folded together. This allows the compact desk 6 to be stored in the storage space 24 of the backpack 8. The folded and stacked resin sheets 72 and 74 may be bound together with rubber bands or strings.

[0043] The procedure for installing the set 1 will be described below with reference to Figs. 9 to 13. First, as shown in Fig. 9, the folded seat 2, shade 4, and desk 6 are removed from the backpack 8, and the seat 2 is unfolded and placed in the work area. Next, as shown in Fig. 10, the shade 4 is unfolded and connected to the seat 2 at the detachable part 54. Next, as shown in Fig. 11, the shade 4 is raised, and the second adjustment strings 58 are connected to the buckles 60 to form the sunshade part 10 on the shade 4.

[0044] Next, as shown in Figure 12, the backpack 8 is unfolded to form the seat 12, and the retaining string 18 of the shade 4 is passed through the handle 22 of the backpack 8 and fastened with the buckle 20 to connect and hold the backrest 16 and the shade 4 together. At the same time, the desk 6 is assembled and placed on the seat 2, completing the installation of the set 1. Then, as shown in Figure 13, the worker can sit in the seat 12 and work on the computer placed on the workbench 68 of the desk 6.

[0045] When taking a break between tasks, the desk 6 can be used with the work table 68 removed from the top panel 64 as shown in Figure 14. Also, as shown in Figure 15, there is also a work style in which the desk 6 is not used.

[0046] As described above, the outdoor work set 1 of this embodiment is composed of at least the seat 2, the shade 4, and the backpack 8, and the seat 2 and the shade 4 are foldable, and the shade 4 is detachably attached to the seat 2 to provide the worker with sunshade 10. When the desk 6 is in use, the desk 6 is foldable and is placed on the seat 2 for use, and the backpack 8 can be carried by the worker on his back.

[0047] The backpack 8 has a storage space 24 that can store the folded seat 2, shade 4, and desk 6, respectively, and the storage space 24 is partitioned by a storage section 26 that contacts the back of the worker and a lid section 28 that covers the storage section 26 from the outside of the backpack 8. By unfolding the lid section 28 over the storage section 26, the backpack 8 can be placed on the seat 2 for use and can also be used as a legless chair 12 that the worker can sit on and lean their back against.

[0048] By dividing the storage space 24 of the backpack 8 into a storage section 26 that contacts the worker's back and a lid section 28 that covers the storage section 26 from the outside of the backpack 8, it is possible to make the outward protrusion of the backpack 8 extremely thin. This allows the backpack 8 to function as a chair 12, while ensuring in the outdoor work set 1 a storage space 24 that can efficiently store the seat 2, shade 4, and desk 6, as well as work-related items such as a computer and documents.

[0049] Furthermore, when the backpack 8 is placed in the seat 12 position, the sunshade 10 of the shade 4 can block the sunlight outdoors. This outdoor work set 1 is compact and has a simple, lightweight structure for easy storage, allowing you to comfortably carry out work-related tasks outdoors whenever you feel like it. Therefore, it is possible to quickly create the environment necessary for outdoor work, and by adding the outdoors to your work style options, it contributes to promoting work style reform.

[0050] More specifically, when in the state of the backpack 8, the storage section 26 is composed of a bottom surface 30, opposing side surfaces 32, and a back surface 34. When in the state of the backpack 8, the lid section 28 is composed of an outer surface 36 that is flexibly connected to the bottom surface 30 and faces the back surface 34, and an upper surface 38 that is flexibly connected to the outer surface 36 and faces the bottom surface 30, and together with the storage section 26, defines the storage space 24. This ensures that the backpack 8 is provided with a minimum amount of storage space 24 that can hold the seat 2, shade 4, desk 6, and other luggage.

[0051] Furthermore, the bottom surface 30, outer surface 36, and top surface 38 of the backpack 8 form the seat 14 that supports the lower body of a seated worker when the backpack is in the seat chair 12 state. The back surface 34 of the backpack 8 forms the backrest 16 that supports the back of a seated worker when the backpack is in the seat chair 12 state. The two side surfaces 32 of the backpack 8 form side covers 44 that respectively cover the left and right sides of the upper body of a seated worker when the backpack is in the seat chair 12 state. This reliably ensures the comfort of a seated worker. In particular, by having the two side surfaces 32 of the backpack 8 form the side covers 44, the seated worker feels more supported, further improving comfort during work.

[0052] Additionally, the outdoor work set 1 has a retaining cord 18 that connects and holds the backrest 16 and the shade 4 when the chair 12 is in use. This secures the shade 4 to the chair 12 and prevents the shade 4 from swaying in the wind outdoors, further improving the comfort of the seated worker.

[0053] Additionally, the backpack 8 has an expandable first adjustment cord 50 that connects the backrest 16 or the side cover 44 to the seat 14 when in the state of the legless chair 12. As a result, by expanding or contracting the first adjustment cord 50, the angle of the backrest 16 relative to the seat 14, i.e., the reclining angle of the legless chair 12, can be adjusted. Therefore, the reclining angle can be easily adjusted to the worker's preferred angle, further improving the comfort of the seated worker.

[0054] Furthermore, the shade 4 has an extendable second adjustment cord 58 that connects the front end 2a of the seat 2 to the front end 4a of the shade 4 when the shade 4 is in the seat chair 12 state. This fixes the raised shade 4 to the seat 2 side, making it possible to more effectively prevent the shade 4 from swaying in the wind outdoors. Furthermore, by extending or contracting the second adjustment cord 58, the angle of the sunshade part 10 can be adjusted according to the sunlight, further improving the comfort of the seated worker.

[0055] The shade 4 has a core 56 at its outer edge, and can be transitioned between a folded state and an unfolded state by bending the core 56, and when in the state of a seat 12, the shade 4 forms the sunshade part 10 by being in the unfolded state. More specifically, when the shade 4 is in the unfolded state, the seat 2 is attached to the detachable part 54, and the holding string 18 is passed through the handle 22 of the backpack 8 to connect and hold the backrest 16 and the shade 4.

[0056] Furthermore, by shortening the length of the second adjustment cord 58, the core material 56 curves, and a curved region 62 serving as the sunshade 10 is formed at the front end 4a of the shade 4. This allows the shade 4 to be easily folded and unfolded, and by extending or shortening the second adjustment cord 58, the angle of the sunshade 10 can be easily adjusted according to the sunlight. This further improves the comfort of the seated worker.

[0057] Second Embodiment An outdoor work set 1 according to a second embodiment of the present invention will be described below with reference to Figs. 16 to 32. Components common to the first embodiment will be denoted by the same reference numerals in the drawings or text, and explanations will be omitted. Components different from the first embodiment will be mainly described. Fig. 16 shows a perspective view of an example of the use state of the set 1 according to the second embodiment, and Fig. 17 shows a rear view of Fig. 16 as seen from behind.

[0058] When in the state of the seat chair 12, the lower end of each pole 120 abuts against the seat 2 or the surface on which the seat 2 is placed (the ground). When in the state of the seat chair 12, the poles 120 are inserted into the handle 22 of the backpack 8 in a crossed state. The backpack 8 has retaining rings 122 at the bottom on both sides in the width direction of the backrest 16, through which the lower end of each pole 120 is inserted and held. The intersection 124 of each pole 120 in the crossed state is positioned near the handle 22, and the intersection 124 is fixed with a cable tie 126. In addition, a plurality of side pockets 128 are formed on the sides of the backpack 8.

[0059] FIG. 18 shows a plan view of a shade 4 according to the second embodiment. The shade 4 of this embodiment does not have the holding cord 18 and detachable portion 54 of the first embodiment, but instead has pole sleeves 130 at both widthwise ends of the rear end 4b. Each pole sleeve 130 defines a holding portion 132 for the pole 120. The upper end of each pole 120 is inserted into each holding portion 132 and held therein. The shade 4 of this embodiment is installed in a substantially horizontal position when unfolded. Therefore, unlike the first embodiment, the front end 4a of the shade 4 does not have a curved region 62 serving as the sunshade 10, and the entire surface of the shade 4 can be used as the sunshade 10.

[0060] Figure 19 shows an assembly diagram of the pole 120. Each pole 120 is made up of a plurality of, for example, three split pole sections 134, 136, and 138. By attaching and detaching each of the split pole sections 134 to 138 to one another, the pole 120 can be shifted between a split state and a connected state. Specifically, the split pole section 134 has a protrusion 134a at one end that protrudes in the axial direction.

[0061] Split pole section 136 has at one end a recess 136a into which protrusion 134a is inserted in the axial direction, and at the other end a protrusion 136b protruding in the axial direction. Split pole section 138 has at one end a recess 138a into which protrusion 136b is inserted in the axial direction. By inserting protrusion 134a into recess 136a and protrusion 136b into recess 138a, split pole sections 134 to 138 are connected to form pole 120.

[0062] 20 shows the split pole portions 134 to 138 bundled together. The binding bands 126 that secure the intersections 124 of the poles 120 when the chair 12 is in the folded position are used to bundle the split pole portions 134 to 138 together and store them compactly in the backpack 8. The split pole portions 134 to 138 of the pole 120 may be connected by wires (e.g., rubber bands) (not shown) at positions that do not interfere with the division and connection of the pole portions.

[0063] In this case, the divided pole sections 134 to 138 connected by wire are detached from each other, and the pole sections 134 to 138 connected by wire are bent and bundled together to make the pole 120 more compact. This makes it easier to assemble the divided pole sections 134 to 138 and also makes it possible to prevent the divided pole sections 134 to 138 from being lost.

[0064] FIG. 21 shows a perspective view of a desk 140 according to the second embodiment. The desk 140 shown in FIG. 21 does not have a work table 68, and does not have any locking holes 112 for attaching the work table 68 to the top surface portion 98 of the table top 4. Furthermore, finger holes 114 formed in each leg 66 are formed by cutting out the resin sheet 74, rather than by perforating the resin sheet 74 as in the first embodiment. Along with the formation of the finger holes 114, bendable pieces 142 are formed in the resin sheet 74.

[0065] FIG. 22 shows a development view of the resin sheet 74 that forms the top plate 64 and each leg 66 of the desk 140 in FIG. 21. In FIG. 22, the left-right direction is the longitudinal direction of the resin sheet 74, and the up-down direction is the width direction of the resin sheet 74. In this embodiment, the portion of the resin sheet 74 that forms the top plate 64 is composed of a top surface portion 98 and a back surface portion 144. The resin sheet 74 that forms the back surface portion 144 extends in the width direction from the resin sheet 74 that forms the top surface portion 98, with a reinforcing portion 104 separating them.

[0066] On both sides in the width direction of the resin sheet 74, at the boundary between the reinforcing portion 104 and the back surface portion 144, eighth fold lines 146 and ninth fold lines 148 that reduce the thickness of the resin sheet 74 are formed over the entire longitudinal direction. This allows the resin sheet 74 to be folded at the eighth fold line 146 and the ninth fold line 148.

[0067] Furthermore, at both widthwise ends of the resin sheet 74, tenth and eleventh fold lines 150 and 152 that reduce the thickness of the resin sheet 74 are formed over the entire longitudinal direction at positions that are narrow enough to ensure the area of ​​the back surface portion 144 from the end edges. This allows the resin sheet 74 to be folded at the tenth and eleventh fold lines 150 and 152. These folded portions form reinforcing portions 154 of the top plate 64.

[0068] A bulge 156 that bulges out in the width direction is formed at both longitudinal ends of each reinforcing portion 154. A notch 158 is made in each bulge 156. Meanwhile, a twelfth fold line 160 that reduces the thickness of the resin sheet 74 is formed in the resin sheet 74 that becomes each leg 66 at the boundary with the piece 142. By folding the piece 142 at the twelfth fold line 160, a finger hole 114 is formed in each leg 66. Also, a notch 162 is made in the edge of each piece 142 that faces the finger hole 114.

[0069] 23 and 24, the procedure for assembling the resin sheet 74 to the top plate 64 will be described below. Note that a description of the same procedures as in the first embodiment will be omitted. First, as shown in FIG. 23, each back surface portion 144 is folded in the direction indicated by the arrow so as to overlap with the top surface portion 96. As a result, the resin sheet 74 is folded at 90° along the sixth fold line 100, the seventh fold line 102, and the eighth fold line 146 and the ninth fold line 148.

[0070] Furthermore, by folding the resin sheet 74 at 90° along the tenth and eleventh folding lines 150 and 152, the reinforcing portions 154 are erected in an overlapping state, and each reinforcing portion 154 can be picked up and held by hand. At this time, the bulging portions 156 formed on each reinforcing portion 154 are also overlapped.

[0071] Next, as shown in Figure 24, the resin sheet 74 is folded along the fourth fold line 94 and the fifth fold line 96 to raise each leg 66 as indicated by the arrows. Then, the notches 158 of each of the overlapping bulges 156 are inserted into the notches 162 of the pieces 142 of each leg 66 to engage them. As a result, the top panel 64 is formed from the top surface portion 96 and the back surface portion 14, and the top panel 64 is fixed to each leg 66, completing the assembly of the desk 140 shown in Figure 21.

[0072] Figure 25 shows a cross-sectional view of the top plate 64 as seen from the direction AA in Figure 21. The top plate 64 is doubled by the top surface portion 96 and the back surface portion 14, thereby improving its rigidity. Furthermore, the top plate 64 and each leg 66 are provided with the reinforcing function of each reinforcing portion 154 in addition to each reinforcing portion 104, further improving the rigidity of the top plate 64. Furthermore, the top plate 64 and each leg 66 are connected by fitting each snap button 110.

[0073] In addition, the notches 158 of the bulging portions 156 of the reinforcing portions 154 engage with the notches 162 of the segments 142 of the legs 66, thereby connecting the top plate 64 and the legs 66 even more firmly. As a result, even if a relatively heavy object is placed on the desk 140 or a worker rests their elbows on the desk 140 while working, the desk 140 will not deform and the shape of the desk 140 will be stably maintained.

[0074] 26 to 28, the procedure for folding the desk 140 will be described below. First, as shown in Fig. 26, the snap buttons 110 are released from their engagement, and the notches 158 in the bulges 156 of the reinforcing parts 154 are disengaged from the notches 162 in the segments 142 of the legs 66. Next, the legs 66 are folded so that they overlap the top surface 98.

[0075] At this time, the reinforcing portions 104 and 154 are also folded so as to overlap the top surface portion 98, and the bulging portions 156 of the reinforcing portions 154 are overlapped. As a result, the back surface portion 144 is overlapped on the top surface portion 98 and becomes flat, so that the resin sheet 74 can be folded at the third fold line 92, and also at the fourth fold line 94 and the fifth fold line 96.

[0076] Figure 27 shows the resin sheet 74 in the state shown in Figure 26 folded. The resin sheet 74 is mountain-folded at the third fold line 92, and further valley-folded at the fourth fold line 94 and the fifth fold line 96. Figure 28 shows the resin sheet 74 in the state shown in Figure 27 folded into a compact state. In this way, the desk 140 of this embodiment can be stored in the storage space 24 of the backpack 8 in a compact folded state, similar to the first embodiment.

[0077] 29 to 32, the procedure for setting up the set 1 will be described below. Note that the description of the same procedures as in the first embodiment will be omitted. First, as shown in FIG. 29, the folded seat 2, shade 4, and desk 140, as well as the bundled divided pole parts 134 to 138, are removed from the backpack 8, and the backpack 8 is unfolded to form the seat chair 12.

[0078] Next, the divided pole portions 134 to 138 are connected and assembled into each pole 120. Next, the poles 120 are crossed to form intersections 124, and with the intersections 124 tied together with cable ties 126, each pole 120 is inserted through the handle 22 of the backpack 8. At this time, the intersections 124 are positioned near the handle 22. Additionally, the lower ends of each pole 120 are inserted through the retaining rings 122 of the backpack 8, and the lower ends of each pole 120 are brought into contact with the seat 2 or the ground. This holds each pole 120 in an upright position.

[0079] Next, as shown in Figure 30, the shade 4 is unfolded, and the upper end of each pole 120 is inserted into and held in the holding portion 132 of each pole sleeve 130. This attaches the rear end 4b of the shade 4 to each pole 120. Because the shade 4 is lightweight and has a core material 56 provided inside, the rear end 4b is cantilevered onto each pole 120.

[0080] Next, as shown in Fig. 31, the front end 4a of the shade 4 and the front end 2a of the seat 2 are connected via the second adjustment cords 58 by connecting the buckles 60. The second adjustment cords 58 can be extended or contracted by operating the adjusters of the buckles 60, thereby adjusting the bending angle of the shade 4. Furthermore, as shown in Fig. 32, the position of the shade 4 can be adjusted forward or backward in the longitudinal direction X by adjusting the position of the lower end of each pole 120 while the worker is seated on the chair 12.

[0081] The lower end of each pole 120 is inserted into the retaining ring 122 of the backpack 8, so even if the lower end of each pole 120 is moved, the poles 120 and, therefore, the shade 4 will not fall over. It is also preferable to pull the lower end of each pole 120 toward the seat 14 of the chair 12 and tilt each pole 120 along the backrest 16 of the chair 12. This allows the shade 4 to be supported in an even more stable position.

[0082] As described above, the outdoor work set 1 of this embodiment, like the first embodiment, is compact and has a simple and lightweight structure for storage. Therefore, by using the set 1, you can easily and comfortably perform work-related tasks outdoors whenever you feel like it. Therefore, it is possible to quickly create the environment necessary for work outdoors, and by adding the outdoors to your work style options, it contributes to promoting work style reform.

[0083] In particular, the set 1 of this embodiment includes a pair of poles 120 that support the rear end 4b of the shade 4 in the longitudinal direction X. When the backpack 8 is in the state of a seat 12, the lower end of each pole 120 abuts against the seat 2 or the ground, respectively. Furthermore, each pole 120 is inserted in a crossed state into a handle 22 formed on the upper part of the backrest 16 of the backpack 8.

[0084] As a result, the shade 4 is supported with its weight directly applied to the backpack 8 and the ground via the poles 120. Therefore, the shade 4 is supported more stably than in the first embodiment. Furthermore, because only the poles 120 exist between the shade 4 and the seat 12, ventilation is improved and shaking of the shade 4 due to wind is more effectively suppressed, further improving the comfort of the seated worker.

[0085] Furthermore, the backpack 8 has retaining rings 122 at the bottom on both sides in the width direction of the backrest 16, through which the lower end of each pole 120 is inserted and held. This allows the lower end of each pole 120 to be supported by the backpack 8, thereby achieving even more stable support for each pole 120 and, ultimately, the shade 4. Furthermore, by inserting the lower end of each pole 120 into the retaining rings 122 of the backpack 8, the worker can adjust the position of the lower end of each pole 120 while seated on the chair 12, thereby adjusting the position of the shade 4 forward or backward.

[0086] This makes it easy to adjust the sunshade range provided by the shade 4 depending on the sunlight. In particular, it is preferable to pull the lower end of each pole 120 toward the seat 14 of the floor chair 12 and tilt each pole 120 along the backrest 16 of the floor chair 12. As a result, most of the weight of the shade 4 is applied to the ground via each pole 120, and also to the backpack 8 via each pole 120 and the handle 22. Therefore, the shade 4 is supported in an even more stable position, and even if the worker leaves the floor chair 12, the poles 120 and the backrest 16 will not collapse due to the weight of the shade 4.

[0087] The shade 4 also has pole sleeves 130 on both sides in the width direction of the rear end 4b, into which the upper ends of the poles 120 are inserted and held. This allows the rear end 4b of the shade 4 to be supported by the upper ends of the poles 120 via the pole sleeves 130. Furthermore, by supporting the upper ends of the poles 120 with the pole sleeves 130, the entire surface of the shade 4 can be used as a sunshade 10 without bending the shade 4. This effectively blocks sunlight, further improving the comfort of seated workers.

[0088] Furthermore, the intersection 124 of each pole 120 in the crossed state is positioned near the handle 22 of the backpack 8. This allows each pole 120 to be supported by the handle 22 near the intersection 124, thereby achieving even more stable support for each pole 120 and therefore the shade 4.

[0089] Each pole 120 is made up of a plurality of divided pole sections 134 to 138, and can be shifted between a divided state and a connected state by attaching and detaching the divided pole sections 134 to 138 to each other. This allows each pole 120 to be stored in the storage space 24 of the backpack 8 in a compact divided and bundled state.

[0090] The set also includes a binding band 126 that secures the intersection 124 when the pole sections 120 are connected and binds the split pole sections 134 to 138 when the pole sections 120 are separated. This stabilizes the pole sections 120 in the intersection state and also makes the poles 120 more compact when separated. This improves the worker's workability when assembling the set 1 and storing it in the backpack 8.

[0091] This concludes the description of the embodiments of the present invention, but the present invention is not limited to the above embodiments and can be modified in various ways without departing from the spirit of the present invention. For example, the shapes of the seat 2, shade 4, desk 6, backpack 8, and each pole 120, the folding structure of the shade 4 and desk 6, 140, the unfolding structure of the backpack 8, and the connecting and separating structure of each pole 120 can be modified without departing from the spirit of the present invention, and the present invention is not strictly limited to the above embodiments.

[0092] Furthermore, the outdoor work set 1 described in the above embodiment can be carried along not only when working outdoors, but also when engaging in various outdoor leisure activities, such as picnics, cycling, fishing, swimming in the sea, etc., and used for reading, resting, eating, etc. It can also be used as a rest or nap spot within the office.
