Description

  The present invention relates to a carry bag.

  A typical carry bag has a storage portion for storing a storage item, a handle portion located above the storage portion, and a caster mounted on the lower surface side of the storage portion. By pushing or pulling the caster while it is grounded, even relatively heavy luggage can be easily carried. Above all, in a carry bag in which casters are attached to the four corners on the lower surface side of the storage part, two casters on one side are grounded while the two casters on the other side are floated, The storage portion can be pulled in an inclined state or all four wheels can be grounded and pushed. Therefore, the mode of use can be appropriately selected according to the weight of the stored item, the surrounding environment at the time of use, the physical size and the strength of the user, and the like, which is highly convenient.

  By the way, there are cases where elderly people etc. use such a carry bag for walking assistance. In this case, it is possible to put weight on the carrying portion of the carry bag as a substitute for a cane by pressing with all four wheels in a grounded state.

  Patent Document 1 describes a heel with a caster which can be easily moved even when weight is put on the handle portion. As shown in FIG. 10, the crucible 100 with a caster described in Patent Document 1 has a base frame 110 with casters 160 attached to the four corners of the bottom, and a crucible main body mounted on the base frame 110 to store stored items. There are 120. The base frame 110 is connected to a loading table 130 on which the main body 120 is placed, an extension rod 140 fixed to one side of the loading table 130 and capable of being drawn upward, and the upper edge of the extension rod 140 It has a grip 150. The user can adjust the telescopic rod 140 to an appropriate height, grip the grip 150, and move the crucible 100 with all the casters 160 at the four corners grounded.

  As shown in FIG. 10, in the wedge 100 with a caster described in Patent Document 1, the telescopic rod 140 has a curved shape so as to be stable even when the user puts weight on the grip 150. The grip 150 is configured to be located above the middle portion of the heel body 120 when the user pulls up the grip 150 during use. By positioning the grip 150 above the middle portion of the crucible body 120, it is considered that the crucible 100 is stable against falling even when weight is put on the grip 150.

JP 2004-344355 A

  However, due to the curved shape of the telescopic rod 140, there is a problem that the position of the grip 150 is restricted depending on the pulling amount of the telescopic rod 140. As shown in FIG. 11, the telescopic rod 140 is fixed to one side of the loading table 130, and the portion drawn upward is curved, so it depends on the position to which it is drawn upward. , The horizontal position of the grip 150 will be different. Therefore, when used by a tall user (indicated by a two-dot chain line in FIG. 11), the grip 150 is located above the middle portion of the bag body 120 because the amount of withdrawal H1 is large. In the case of use by a low user (indicated by a solid line in FIG. 11), the grip 150 is located near the one side because the amount of withdrawal H2 is small. As a result, the position at which the user supports the crucible 100 is restricted, and it may be difficult to move the crucible 100 in a stable state.

  The present invention has been made to solve such conventional problems, and its object is to provide a carry bag which can be stably held at any position.

  In order to solve the above problems, the present invention provides a storage portion capable of storing stored items, three or more wheels of castors provided with at least one non-linear line on the lower surface side of the storage portion, and three or more wheels. A carry bag having a shaft portion extending in a substantially vertical direction from the storage portion in a state where the casters are grounded, and a handle portion continuously provided at an upper end of the shaft portion, the handle portion comprising the three wheels It has a plurality of grips which the user grips when moving the above caster in a grounded state, and the plurality of grips are moved when the three or more wheels are grounded. It is provided in an area above the area surrounded by the ground contact portions of the three or more wheels and at different positions in the axial direction of the pivot axis of the casters.

  According to the above configuration, when the casters of three or more wheels provided on the lower surface side of the storage portion of the carry bag are grounded, the carry bag can be in a self-supporting state. When the carry bag can stand on its own, the shaft portion extends in the substantially vertical direction from the storage portion, and the handle portion is continuously provided at the upper end of the shaft portion. Therefore, the handle portion is positioned above the storage when moving the carry bag in a self-standing state.

  The handle portion has a plurality of gripping portions gripped by the user, and the plurality of gripping portions are provided at different positions in the axial direction of the pivot shaft of the caster when moving the carry bag in a self-standing state . Therefore, the user can grip any of the grips selected from the plurality of grips at any position different in the direction orthogonal to the moving direction of the carry bag. For example, when pushing the carry bag by the side of the user, it is possible to grip the grip near the user's own position or to grip the grip remote from the user's side. The user can arbitrarily select and hold a position that he / she can easily hold, without being restricted by the weight of the stored item, the surrounding environment at the time of use, the physical constitution or the force of the user, or the like. The convenience of the carry bag is improved.

  Further, the plurality of grips are provided in an area above the area surrounded by the contact portions of the caster when moving the carry bag in a self-standing state. Therefore, when the carry bag becomes self-supporting or moves in a self-supporting state, when the user grips any of the plurality of grips and applies weight, the ground contact portions of the three or more wheels caster The force will act in the area surrounded by. As a result, even if the user applies weight, the carry bag does not fall easily and is in a stable state.

  It should be noted that the plurality of gripping portions is not limited to the case where each of the plurality of gripping portions included in the handle portion can be clearly distinguished, and also in the case where the plurality of gripping portions are continuously formed and their boundaries can not be clearly identified. Shall be included.

  In the above invention, it further comprises a rectangular support portion on which the storage portion is placed, the casters of three or more wheels are provided on the lower surface of the support portion, and the shaft portion is a side of the support portion The handle portion extends substantially perpendicularly from the upper end of the shaft portion, and the tip end of the handle portion is at an intermediate position between the one side and the other side opposite to the one side. Preferably, it is provided in the other side region.

  In addition, extending in a substantially orthogonal direction from the upper end of the shaft portion is not limited to the case where the handle portion is orthogonal to the upper end of the shaft portion, and the handle portion is continuously provided so as to curve from the upper end of the shaft portion It also includes the case where the shape becomes gradually orthogonal.

In the above invention, preferably, the handle portion is formed in a top view trapezoidal shape.

The frame body 10 has a rectangular bottom support 31 on which the storage body 20 is placed, and a side support 32 having a shape that is orthogonal to the bottom support 31 on the back side of the bottom support 31. . One caster 60 is attached to one corner of each of the four corners of the lower surface of the bottom surface support 31. Further, the frame body 10 has a shaft portion 40 having a shape extending upward along the side support portion 32 and a handle portion 50 having a shape orthogonal to the shaft portion 40 from the upper end of the shaft portion 40.

  The material of the pipe-like member constituting the frame body 10 is not particularly limited. For example, fiber reinforced resin materials such as carbon fiber reinforced resin, glass fiber reinforced resin, polyethylene fiber reinforced resin, metal materials such as iron and aluminum, polyamide Thermoplastic resin materials, such as resin and a polyurethane resin, etc. are mentioned. Among them, it is preferable to be formed of a carbon fiber reinforced resin which is lightweight and excellent in strength. The cross-sectional shape of the pipe-shaped member is not particularly limited, and may be rectangular in cross section, elliptical in cross section, or circular in cross section. Furthermore, the diameter of the pipe-like member is not particularly limited, and can be appropriately set in consideration of strength required for the carry bag, operability, etc., or ease of processing. The diameters of the pipe-like members may be the same for all of the bottom surface support 31, the side surface support 32, the shaft 40, and the handle 50, and may be different for at least one of them.

  As shown in FIG. 2A, the rectangular bottom support 31 has two long sides 31a extending in the longitudinal direction and two short sides 31b extending in the short direction. The outer edge of the rectangle formed of the long side portion 31a and the short side portion 31b has substantially the same size as the outer edge of the bottom surface 20a of the storage main body 20 described later.

  The side support portion 32 having a shape orthogonal to the bottom support portion 31 has a rectangular shape which is slightly shorter in the vertical direction than in the lateral direction, and has two short sides 32 b extending in the short direction (vertical direction) It has two long sides 32a extending in the direction (lateral direction). The two short sides 32 b extend upward from both ends of the long side 31 a on the back side of the bottom support 31, and the lower long side 32 a of the side support 32 is the back of the bottom support 31. It is made into the same member common to the long side part 31a of the side. The outer edge of the rectangle formed of the long side 32a and the short side 32b is substantially the same size as the outer edge of the side face 20b on the back side of the storage main body 20 described later.

  As shown in FIG. 3, casters 60 provided at four corners of the lower surface of the bottom surface support 31 are attached to the bottom surface support 31 by a mounting shaft 61 extending in a direction orthogonal to the bottom surface support 31. The caster 60 is capable of freely rotating around the mounting shaft 61 by 360 degrees. The frame body 10 is capable of being free standing and movable in any direction in a state where the four wheels 60 are in contact with the ground. In addition, since all four wheels of the caster 60 can freely rotate 360 degrees around the mounting shaft 61, when moving in any direction, the pivoting shafts 62 of all the casters 60 are identical. Direct the direction. For example, when moving in the arrow direction in FIG. 5 in which the carry bag is viewed from above, the pivot shafts 62 of all the casters 60 point in a direction orthogonal to the arrow direction which is the moving direction.

  As shown in FIG. 2A, the shaft portion 40 has two shafts 41 and 42 extending upward from an intermediate portion of the long side portion 31a on the back surface side of the bottom surface support portion 31. The shafts 41 and 42 are joined to the upper and lower long side portions 32 a of the side surface support portion 32 respectively. Of the shafts 41 and 42, a portion above the long side portion 32a on the upper side of the side surface support portion 32 can be expanded and contracted by an expansion and contraction mechanism (not shown). Specifically, the state in which the upper end portions of the shafts 41 and 42 are located on the upper long side portion 32 a of the side surface support portion 32 is expandable and contractible with the shortest length. Further, the shafts 41 and 42 can be fixed at an arbitrary length by a stopper mechanism (not shown).

  As shown in FIG. 2A, the handle portion 50 has a shape orthogonal to the shafts 41 and 42 from the upper ends of the two shafts 41 and 42. Therefore, in a state in which the four casters 60 are in contact with the ground, the handle portion 50 extends in a substantially horizontal direction with respect to the installation surface.

  As shown in FIG. 4, the handle portion 50 of the present embodiment is formed in a trapezoidal shape in top view. Specifically, it is formed in a trapezoidal shape in which the shaft portion 40 side, that is, the back side of the carry bag is wide. The length L 1 on the back side of the handle portion 50 is longer than the distance L 2 between the two shafts 41 and 42. And, when the user moves the front side of the carry bag by placing it on the side of itself (the state shown in FIG. 6 (a)), the front end edge of the portion on the back side of the handle portion 50 is on the front side. It is located on the front side of the provided shaft 41, and its rear edge is located on the rear side of the shaft 42 provided on the rear side.

  As shown in FIG. 4, the two corner portions 50 a on the back side of the handle portion 50 and the two corner portions 50 b on the front side have an R shape. It is preferable that the corner 50b on the front side is R 50 mm or more with reference to the central axis of the pipe-like members constituting the shafts 41 and 42. Specifically, when used in the state shown in FIG. 6A, the corner 50b located on the front side is R 50 mm or more based on the central axis of the shaft 42 located on the rear side, and is located on the rear side Preferably, the corner 50b to be cut is R 50 mm or more with respect to the central axis of the shaft 41 located on the front side. Further, it is preferable that the corner 50 b located on the front side and the corner 50 b located on the rear side have the same R.

  As shown in FIGS. 4 and 5, the handle portion 50 is provided with a plurality of gripping portions 51, 52, 53 which the user grips when moving in a state where the four casters 60 are in contact with the ground. In the handle portion 50 of the present embodiment formed into a trapezoidal shape in top view, when the user moves the front side of the carry bag with the front side of the carry bag positioned in the side (the state shown in FIG. 6A), First gripping portion 51 extending in the second direction, a second gripping portion 52 extending diagonally forward from the front end edge of the first gripping portion 51, and a third gripping portion extending diagonally backward from the rear end edge of the first gripping portion 51 53 are provided. The user can select and hold these holding portions 51, 52, 53 as appropriate. In addition, since the grips 51, 52, 53 are formed in a continuous shape in the handle 50, the user is able to form an R shape between the first grip 51 and the second grip 52. It is also possible to appropriately select and grip a portion and an R-shaped portion between the first gripping portion 51 and the third gripping portion 53. For the sake of convenience, in the handle portion 50, a portion connecting the rear end side edge of the second grip portion 52 and the rear end side edge of the third grip portion 53 is referred to as a connecting portion 55.

  As shown in FIG. 3 and FIG. 5, when moving the four-wheel casters 60 in a state in which the four-wheel casters 60 are in contact with the four grips 51, 52, 53, the grips 51, 52, 53 Provided in the area of In FIG. 5, since the carry bag is viewed from above, the ground contact portions 63 of the four-wheel casters 60 overlap the pivot shaft 62 of the casters 60. Further, the tip end of the handle portion 50 is provided at a position deviated to the front side from an intermediate position C between the back side and the front side of the carry bag.

  As shown in FIG. 2 (b), the storage body 20 of the present embodiment is formed in a rectangular box shape. Although the material which comprises the storage main body 20 is not specifically limited, For example, the material similar to the flame | frame body 10 is mentioned. Further, it may be a cloth product made of a knitted fabric, a woven fabric, a non-woven fabric or the like, a leather product or the like.

  The storage main body 20 of the present embodiment has an opening (not shown) formed on the side surface on the front side, and places the storage thing into the storage main body 20 through the opening part and takes out the storage thing from the storage main body 20 be able to. The shape of the opening, the formation position, and the like are not particularly limited, and can be determined as appropriate. Moreover, not the side surface of the front side of the storage main body 20 but the upper surface of the storage main body 20 may be formed, and it may be formed ranging from an upper surface to a side surface.

  As shown in FIG. 2B, the bottom surface 20a of the storage main body 20 is formed with a recess 20c having a shape that is cut out over the entire outer peripheral edge thereof. In addition, on the side surface 20b on the back surface side of the storage main body 20, a recessed portion 20d having a shape that is cut out is formed over the entire outer peripheral edge. The recess 20 c is shaped to match the rectangular shape formed by the long side 31 a and the short side 31 b of the bottom surface support 31 of the frame body 10. In addition, the recess 20 d has a shape that matches the shape of the long side 32 a and the short side 32 b of the side surface support portion 32 of the frame body 10. Therefore, when the bottom surface 20a of the storage body 20 is placed on the bottom surface support portion 31 of the frame body 10, the long side portion 31a and the short side portion 31b of the bottom surface support portion 31 are accommodated in the recess 20c of the bottom surface 20a of the storage body 20. The long side 32a and the short side 32b of the side support portion 32 fit in the recess 20d of the side 20b on the rear side of the storage main body 20. Thereby, the storage main body 20 is stably supported on the frame body 10.

Next, the operation of the carry bag of the present embodiment will be described.
As shown in FIG. 6 (a), the user grounds all the four casters 60 of the carry bag, and the telescopic mechanism and stopper mechanism provided on the shaft portion 40 make the handle portion 50 easy to hold by itself. Adjust to become Then, with the front side of the carry bag positioned beside itself, the user holds any position selected from the first holding portion 51, the second holding portion 52, and the third holding portion 53 provided on the handle portion 50. . At this time, as shown in FIG. 5, the grips 51, 52, 53 are provided in the upper region of the region surrounded by the ground contact portions 63 of the four wheels 60. Therefore, in this state, when the user puts weight on the handle portion 50 and pushes the carry bag, the force applied to the handle portion 50 acts within the area surrounded by the ground portions 63 of the four wheels of the castor 60. It will be done. Therefore, the carry bag is stably supported.

  As shown in FIG. 5, the first gripping portion 51, the second gripping portion 52, and the third gripping portion 53 have different positions in the axial direction of the pivot shaft 62 of the caster 60 when moving the carry bag in a self-supporting state. Provided in That is, when the user grips the handle portion 50 in a state where the front side of the carry bag is positioned beside the first grip portion 51, the second grip portion 52, and the third grip portion 53, Provided at different positions on the side of the Therefore, the user can hold the first holding unit 51 close to the user, or can hold the second holding unit 52 or the third holding unit 53 at a position far from the user. The user can freely select and grip the gripping portions 51, 52, 53 at positions where the user can easily grip.

  Further, as shown in FIGS. 7A to 7C, the user can select an arbitrary gripping portion from the gripping portions 51, 52, and 53 depending on the position of the carry bag relative to the user. As shown in FIG. 7 (a), when the user wants to move the carry bag in the state of being positioned beside him / her, the user may hold the first grip 51 at a close position. On the other hand, as shown in FIG. 7 (b), when the user wants to move the carry bag obliquely forward of the user's own, the user may grip the rear side third grip portion 53 at the near position. Then, as shown in FIG. 7 (c), when the user wants to move the carry bag obliquely behind the user, the user may hold the second grip 52 on the front side at a close position. Since the handle portion 50 is formed in a trapezoidal shape in a top view, the second grip portion 52 and the third grip portion 53 are a carry bag when it is desired to move the carry bag in a state of being positioned diagonally forward or diagonally backward of itself. Therefore, the user can grip the second grip portion 52 and the third grip portion 53 without difficulty.

  Also, as indicated by the two-dot chain lines in FIGS. 7A to 7C, when holding any of the holding portions 51, 52, 53, any position in each of the holding portions 51, 52, 53 It can be gripped. And since each holding part 51, 52, 53 is formed in the shape provided in a row, the R-shaped part between the 1st holding part 51 and the 2nd holding part 52, and the 1st holding part 51 It is also possible to appropriately select and grip an R-shaped portion between the third grip portion 53 and the third grip portion 53.

  As shown in FIG. 6 (b), the rod-shaped wedge 100 described in Patent Document 1 is used in a state in which the telescopic rod 140 side is positioned to the side of itself. Also, due to the curved shape of the telescopic rod 140, the horizontal position of the grip 150 changes depending on the amount by which the telescopic rod 140 is pulled out. The horizontal position of the grip 150 is easily influenced by the physical constitution of the user.

  In this respect, in the carry bag of the present embodiment, as shown in FIG. 6A, the first gripping portion 51 at the tip of the handle portion 50 always has a constant horizontal position regardless of the amount of withdrawal of the shaft portion 40. It is. Therefore, the horizontal positions of the grips 51, 52, 53 are not easily influenced by the physical constitution of the user.

  Further, in the case of the conventional caster-equipped crucible 100, the grip 150 is between the back side and the front side of the crucible 100 even when the grip 150 is pulled out to the highest position with the largest amount of pulling out of the telescopic rod 140. It is located on the side closer to the front than the intermediate position C, that is, on the side closer to the telescopic rod 140. Therefore, when the user moves the front side of the wheeled crucible 100 in a state where the front side of the wheeled crucible 100 is positioned next to the user's side, if the weight 150 is put on the grip 150, the cage 100 tends to fall to the user side.

  In this respect, in the carry bag of the present embodiment, as shown in FIG. 5, the first grip portion 51 at the tip of the handle portion 50 is a long side 31 a on the back side of the bottom surface support 31 and a long side on the back side. It is provided in the area | region by the side of the long side part 31a of the front from the intermediate position C of the long side part 31a of the front side by which the part 31a is opposite. That is, the first grip portion 51 is located on the side away from the shafts 41 and 42 extending upward from the middle portion of the long side portion 31 a on the back surface side of the frame body 10. Moreover, the 1st holding part 51 of the front-end | tip of the handle part 50 is constant irrespective of the withdrawal amount. Therefore, when the user moves the front side of the carry bag with the front side of the carry bag positioned sideways, the carry bag does not easily fall even when weight is put on the handle portion 50, and the carry bag is supported in a stable state .

Next, the effect of the carry bag of the present embodiment will be described.
(1) In the carry bag of the present embodiment, four wheels of castors 60 are attached to the lower surface side of the bottom surface support portion 31 of the storage main body 20, and the carry bag can stand by itself when the four wheels of casters 60 are grounded. It becomes a state. Then, when the carry bag is in a state where it can stand on its own, the shaft portion 40 extends in a substantially vertical direction from the bottom surface support portion 31 and the handle portion 50 extends in a substantially horizontal direction from the upper end of the shaft portion 40 . At this time, the grip portions 51, 52, 53 provided on the handle portion 50 are provided in the upper region of the region surrounded by the ground contact portions 63 of the casters 60 of four wheels. Therefore, in a state where the carry bag can stand on its own, when the user grips each of the grips 51, 52, 53 of the handle 50 and applies weight, the area enclosed by the ground portions 63 of the four wheels 60 is Power acts on the As a result, even if the user applies weight when pushing the carry bag, the carry bag is unlikely to fall down and a stable feeling of use can be obtained.

  (2) The first gripping portion 51, the second gripping portion 52, and the third gripping portion 53 provided in the carry bag of the present embodiment are the pivot shaft 62 of the caster 60 when moving the carry bag in a self-standing state. At different positions in the axial direction of Therefore, the user can grip the handle portion 50 at any position different in the direction orthogonal to the moving direction of the carry bag. For example, when the user presses the carry bag beside itself (the state shown in FIG. 6A), the user can grip the first grip portion 51 close to himself or The second grip portion 52 and the third grip portion 53 can be gripped. The user can freely select and hold the grips 51, 52, 53 at a position where he / she can easily grip, without being restricted by the physical constitution of the user.

  (3) The handle portion 50 provided in the carry bag of the present embodiment is formed in a trapezoidal shape in top view, and is obliquely forward from the front end edge of the first grip portion 51 extending in the front-rear direction and the front end edge of the first grip portion 51 And a third gripping portion 53 extending diagonally rearward from the rear end edge of the first gripping portion 51. Therefore, it is easy for the user to hold the carry bag when it is desired to move the carry bag obliquely forward of the user or when the user wants to move the carry bag obliquely backward of the user.

  When the handle portion 50 is formed in a rectangular shape in top view, the gripping portions corresponding to the second gripping portion 52 and the third gripping portion 53 of the present embodiment extend straight along the width direction of the carry bag. . In this case, when the user wants to move the carry bag obliquely forward or backward, the wrist must be bent in accordance with the grip extending straight along the width direction of the carry bag. Therefore, it is difficult to grip the wrist by applying an excessive force, and it is difficult to move the carry bag. By contrast, with the shape of the handle portion 50 provided in the carry bag of the present embodiment, the user can grip the second grip portion 52 and the third grip portion 53 without difficulty.

  (3) When the load in the storage main body 20 is heavy because, for example, the third grip portion 53 extends obliquely backward, the user positions the carry bag diagonally forward of the user and the third grip portion The carrier bag may be moved by pressing it while holding the handle 53 obliquely from the rear. At this time, the user can hold an arbitrary position in the third holding unit 53 in accordance with his / her physical constitution and the like. In addition, since the second grip portion 52 extends diagonally forward, for example, when the passage width to be moved is narrow, the user positions the carry bag diagonally backward of the user to slant the second grip portion 52. The carrier bag may be moved in a pulling manner while gripping from the front. At this time, the user can hold an arbitrary position in the second holding unit 52 in accordance with his / her physical constitution and the like.
