Embodiment

[0022] Specific embodiments of the present invention will be described with reference to the drawings.

[0023] This embodiment is a working chair with wheels in which wheels 10 are provided at the lower part of a case-shaped main body 1 having a seat surface 5a at the upper part. The case-shaped main body 1 has a storage space S inside, and a lower storage space S1 is provided in the case-shaped main body 1 below the storage space S. A front opening 1a' communicating with this lower storage space S1 is provided in the front surface portion 1a of the case-shaped main body 1. Further, a drawer body 2 stored in the lower storage space S1 through the front opening 1a' is provided. This drawer body 2 is configured to be pullable out from the case-shaped main body 1.

[0024] Note that the work (application scenarios) using this embodiment is not limited to work in fields or gardens (weeding and taking care of plants), but includes a wide variety of work in factories and construction sites, outdoor leisure such as fishing and camping, and use in indoor leisure.

[0025] Hereinafter, each component of the present embodiment will be described in detail.

[0026] The case-shaped main body 1 is formed of an appropriate synthetic resin member as shown in FIGS. 1 to 4. In each case, the wall plate-shaped front portion 1a, rear portion 1b, and left and right side portions 1c are erected on the front, rear, left, and right peripheries of the horizontally rectangular plate-shaped bottom portion 1d, and have an upper surface opening portion 1' that is horizontally rectangular in plan view and has an internal storage space S with an open upper portion.

[0027] In addition, the case-shaped main body 1 is provided with concave tire housing portions 1f for arranging wheels 10 (described later) at the outer four corners of the front, rear, left, and right sides of the lower portion. The tire housing portions 1f are provided in a state of bulging into the storage space S. Further, an axle 11 is rotatably installed between the front and rear tire housing portions 1f on each of the left and right sides of the case-shaped main body 1.

[0028] From this configuration, the axial direction of the axle 11 is the front-rear direction of the case-shaped main body 1, and wheels 10 are provided at both ends of the axle 11 at the portions protruding into the tire housing portions 1f.

[0029] The wheels 10 are formed of an appropriate synthetic resin member as shown in FIGS. 1 to 4, and are rotatably provided in the left-right direction of the case-shaped main body 1 via the axle 11 whose axial direction is the front-rear direction of the case-shaped main body 1 described above.

[0030] Therefore, the user can move the case-shaped main body 1 in the left-right direction using the feet while sitting on the seat surface 5a.

[0031] In addition, the case-shaped main body 1 is provided with a partition body 6 that vertically partitions the inside of the case-shaped main body 1. The upper side of the partition body 6 is configured as a storage space S, and the lower side is configured as a lower storage space S1.

[0032] This partition body 6 is a plate-shaped body formed of an appropriate synthetic resin member as shown in FIGS. 2 and 3. Side partition plate portions 6a are vertically provided at positions on the left and right of the lower surface of the partition body 6. Further, at the four corners of the lower surface of the partition body 6, when the partition body 6 is placed in a bridging state between the tire house portions 1f, fastening plate portions 6b for removably fastening to each of the tire house portions 1f are vertically provided.

[0033] Therefore, by attaching the partition body 6 via the fastening plate portion 6b, a lower storage space S1 surrounded by the rear surface portion 1b and the bottom surface portion 1d of the case-shaped main body 1 and the partition body 6 (side partition plate portion 6a) is formed below the partition body 6. Note that, if necessary, by removing the partition body 6, a large-capacity space in which the storage space S and the lower storage space S1 are combined into one is formed.

[0034] Also, at the lower central portion of the front surface portion 1a of the case-shaped main body 1, a front opening portion 1a' having a rectangular shape in a front view and communicating with the lower storage space S1 is provided, and it is configured such that a drawer body 2 described later can be taken in and out from the front opening portion 1a' into the lower storage space S1.

[0035] At the opening edge portion (or its vicinity) of the front opening portion 1a', a support ridge portion 3 for supporting a sliding rib portion 2a provided on the drawer body 2 and having a length in the left-right direction of the case-shaped main body 1 is provided. This support ridge portion 3 (the portion rising with respect to the bottom surface portion 1d) is configured as a portion to be locked, which is locked to prevent the first locking portion 4A provided at the rear end portion of the drawer body 2 from coming off when the drawer body 2 is pulled out. Further, this portion to be locked is configured to be locked to the second locking portion 4B provided at the front end portion of the drawer body 2 when the drawer body 2 is in a stored state.

[0036] Therefore, when the drawer body 2 is pulled out, the locking between the first locking portion 4A and the locked portion 3 prevents the drawer body 2 from easily coming out of the case-shaped main body 1. Also, for example, when moving on a rough road (a bumpy or inclined road surface) using the wheels 10 or when carrying it by holding the handle portion 1e described later, the locking between the second locking portion 4B and the locked portion 3 prevents the drawer body 2 from unexpectedly popping out even if the case-shaped main body 1 tilts forward (the stored state of the drawer body 2 is maintained). Particularly, when an object is stored in the drawer body 2, if the case-shaped main body 1 tilts forward, the drawer body 2 tends to come out, but this embodiment surely prevents this.

[0037] As shown in FIGS. 1 to 3, the drawer body 2 is an upper-opening storage container formed of an appropriate synthetic resin member, and is configured to close the front opening 1a' when stored in the lower storage space S1.

[0038] Also, on the left and right side edges of the lower surface of the drawer body 2, rail-shaped sliding rib portions 2a having a length in the front-rear direction are provided. A first locking portion 4A is provided at the rear end portion of the sliding rib portion 2a, and a second locking portion 4B is provided at the front end portion of the sliding rib portion 2a.

[0039] As shown in FIGS. 6 and 7, the first locking portion 4A is configured by providing a convex portion protruding downward on the sliding rib portion 2a of the drawer body 2.

[0040] A vertical rising surface 4a' is provided at the front end portion of the first locking portion 4A, and an inclined surface 4a" with a lower protrusion degree toward the rear end is provided at the rear end portion. When the drawer body 2 is pulled, the first locking portion 4A (rising surface 4a') locks with the locked portion 3 to be in a retaining state. This retaining state is released when the front end portion of the drawer body 2 is slightly lifted and the first locking portion 4A (rising surface 4a') disengages from the locked portion 3, and it can be completely pulled out by pulling it out as it is. When inserting the drawer body 2 from the front opening 1a, since the rear end portion of the first locking portion 4A is the inclined surface 4a", it can ride over the locked portion 3 and slide smoothly.

[0041] The second locking portion 4B is configured by providing a convex portion that protrudes downward on the sliding rib portion 2a of the drawer body 2 as shown in FIGS. 6 and 7.

[0042] A vertical rising surface 4b' is provided at the front end portion of the second locking portion 4B, and an inclined surface 4b" with a lower protrusion degree toward the rear side is provided at the rear end portion. By housing the drawer body 2 and locking the second locking portion 4B (rising surface 4b') to the locked portion 3, the housed state of the drawer body 2 is maintained. This holding state is released when the second locking portion 4B (rising surface 4b') is disengaged from the locked portion 3 by slightly lifting the front end portion of the drawer body 2. When the drawer body 2 is pushed in and housed from the pulled-out state, since the rear end portion of the second locking portion 4B is the inclined surface 4b", it can ride over the locked portion 3 and slide smoothly.

[0043] Also, at the upper end portion of the rear surface portion 1b of the case-shaped main body 1, a lid body connecting portion 1g for connecting a lid body 5 described later is provided.

[0044] This lid body connecting portion 1g is a bearing structure portion having a C-shaped cross section that generates diameter-reducing elasticity as shown in FIGS. 2, 3, 5, and 6. It is provided at the left and right positions at the upper end of the rear surface portion 1b, and a pivot shaft 5b provided on the lid body 5 is press-fitted and connected using resin elasticity and is configured to be rotatably supported.

[0045] Also, at the upper end portion of the front surface portion 1a of the case-shaped main body 1, a buckle 1h is provided that locks to the end portion (locking connection portion 5c) of the lid body 5 in the closed state to lock and hold the closed state of the lid body 5.

[0046] Also, a lid body 5 for opening and closing the upper surface opening portion 1' is provided on the case-shaped main body 1.

[0047] This lid body 5 is a plate-like body having a rectangular shape in plan view formed of an appropriate synthetic resin member as shown in FIGS. 1 to 7, and a seating surface portion 5a is provided on the upper surface portion (outer surface portion).

[0048] This seat surface portion 5a is provided in a concave curved shape when viewed from the front (a concave curved surface shape in which the left and right portions are higher than the central portion in the left-right longitudinal direction).

[0049] Therefore, when the user sits on the seat surface portion 5a with the body facing the front-rear direction of this embodiment, the seat surface portion 5a fits well with the sitting buttocks (especially the left and right portions), and moreover, when moving in the left-right direction while sitting, it is difficult for the buttocks to fall off to the left and right sides from the seat surface portion 5a, and the movement is easy.

[0050] Also, pivot shafts 5b are horizontally provided at the left and right positions of the rear end portion of the lid body 5, and each of these pivot shafts 5b is rotatably press-fitted and connected to a lid body connecting portion 1g provided on the case-shaped main body 1.

[0051] Therefore, the lid body 5 can rise and fall with respect to the case-shaped main body 1 to open and close the upper opening 1', and the rising direction for opening the upper opening 1' of the case-shaped main body 1 in this lid body 5 is opposite to the pulling-out direction of the drawer body 2 (see Fig. 2).

[0052] Also, locking connection portions 5c are provided at the left and right positions of the front end portion of the lid body 5, and these locking connection portions 5c are detachably locked and connected to buckles 1h provided on the case-shaped main body 1.

[0053] Also, annular handle portions 1e project horizontally from the left and right side surface portions 1c of the case-shaped main body 1, and further, recesses 1e' for positioning and locking connection members (not shown) such as strings wound around or hooks hooked to the handle portions 1e are provided on the inner peripheral edges of the handle portions 1e.

[0054] Since this embodiment is configured as described above, for example, when working in a field or a garden (such as weeding or taking care of plants), the work chair with wheels according to this embodiment can be arranged and the work can be carried out while sitting on the seat surface portion 5a. Also, when continuing to work at a nearby location, since the case-shaped main body 1 has wheels 10, it is possible to move using the feet while sitting.

[0055] In addition, in this embodiment, the case-shaped main body 1 has a storage space S inside, and a lower storage space S1 is provided in the case-shaped main body 1 below the storage space S. A drawer body 2 to be stored in the lower storage space S1 is provided. The drawer body 2 is configured to be pullable out from the case-shaped main body 1. With this configuration, while sitting, it is possible to take in and out the stored items (tools) in the lower storage space S1 of the case-shaped main body 1 using the drawer body 2, which is very convenient to use and, thus, excellent in workability.

[0056] In addition, in this embodiment, in the front opening 1a' or in the vicinity thereof, when the drawer body 2 is in the stored state, a locked portion 3 for locking with a second locking portion 4B provided at the front end portion of the drawer body 2 is provided. Due to the configuration that the stored state of the drawer body 2 is maintained even when the case-shaped main body 1 tilts forward by the locking between the second locking portion 4B and the locked portion 3, it is possible to prevent the drawer body 2 from unexpectedly popping out from the case-shaped main body 1.

[0057] In addition, in this embodiment, the seat surface portion 5a is the upper surface of an openable and closable lid body 5 provided on the case-shaped main body 1 so as to be able to rise and fall. Since the rising direction of the lid body 5 is configured to be opposite to the pulling-out direction of the drawer body 2, it is possible to smoothly take in and out the stored items with respect to the case-shaped main body 1.

[0058] In addition, in this embodiment, a partition body 6 for partitioning the inside of the case-shaped main body 1 vertically is provided in the case-shaped main body 1. The upper side of the partition body 6 is configured as the storage space S, and the lower side is configured as the lower storage space S1. Therefore, for example, the storage space S and the lower storage space S1 can be selected according to uses, sizes, etc. to store the stored items (tools, etc.), which is convenient to use.

[0059] In addition, in this embodiment, annular handle portions 1e project horizontally from the left and right side surface portions 1c of the case-shaped main body 1. Since recesses 1e' for positioning and locking connecting members such as strings and hooks connected to the handle portions 1e are provided on the inner peripheral edges of the handle portions 1e, it is easy to carry the work chair with wheels by gripping the handle portions 1e. Moreover, the connecting members can be connected to the handle portions 1e in a positioned state.

[0060] In addition, in this embodiment, the case-shaped main body 1 has a rectangular parallelepiped shape, the drawer body 2 is provided so as to be pullable forward of the case-shaped main body 1, and the wheels 10 are provided at the four corners of the case-shaped main body 1 and are rotatably provided so as to move the case-shaped main body 1 in the left-right direction. Therefore, also in this regard, operations and movements can be performed well while sitting, and the above-described operational effects can be surely achieved.

[0061] Note that the present invention is not limited to this embodiment, and the specific configurations of the respective constituent elements can be appropriately designed.
