Description

Technical Field

[0005]

[0001] The present disclosure relates to a carry case provided with a structure for carrying children and infants etc.

Background Art

[0002] In recent years, as a carry case used for travel etc., there has been proposed a shape that enables movement with children and infants (hereinafter referred to as "children etc.") placed on the carry case (Patent Document 1). Patent Document 1 discloses a technique in which the carry case has a substantially L-shaped outer appearance, and an outer peripheral portion bent at approximately 90 degrees is used as a seating surface for children etc., and a pair of grips is provided at a position of the case body higher than the seating surface.

[0003] Children etc. can ride on the carry case in a so-called straddling posture in which they straddle across the seating surface while gripping the grips. A caregiver of children etc. can move while gripping the handle provided on the carry case with the child placed on the carry case in a straddling posture.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the prior art disclosed in Patent Document 1, the carry-on case has a roughly L-shaped exterior in order to allow children to ride on it in a straddling position, which reduces the amount of luggage that can be stored compared to a carry-on case with a typical roughly rectangular exterior. Also, for safety reasons, the grips that children can hold onto are attached to the sides of the case body, which means that the grips can break if the carry-on case is accidentally knocked over, and the case is bulky when placed on the luggage rack of a car or train. Furthermore, in the prior art there is nothing to support the child from behind, so there is a risk that the child may fall out of the carry-on case if it is subjected to any impact while being moved.

[0006] Therefore, the purpose of this disclosure is to provide a carry case that ensures sufficient luggage capacity, prevents bulkiness when placed on the luggage rack, and allows passengers to sit in a stable posture. [Means for solving the problem]

[0007] The carry case of this disclosure comprises a case body comprising a first shell and a second shell; a first grip portion provided on either the first shell or the second shell; a second grip portion provided on either the first shell or the second shell that does not have the first grip portion; and a seat portion that is detachably attached to the first grip portion and the second grip portion and on which a passenger can sit. [Effects of the Invention]

[0008] The carry case of this disclosure ensures ample storage capacity for luggage while preventing bulkiness when placed on the luggage rack, and allows passengers to sit in a stable position. [Brief explanation of the drawing]

[Figure 7] This is a diagram showing the case body of a carry case in one embodiment of the present disclosure in an open state. [Modes for carrying out the invention]

[0010] The carry case 1 in the embodiment of this disclosure will be described with reference to Figures 1 to 7. The carry case 1 has the function of being able to move, for example, a child in the lower grades of elementary school or younger, while they are seated in a stable position. For convenience, in this specification, the person who moves the carry case itself by grasping the first handle (described later) (for example, a guardian of a child, etc.) will be referred to as the "user," and the person who sits in the carry case 1 (a child, etc.) will be referred to as the "passenger."

[0011] The carry case 1 is constructed by providing the following components to the case body 2. In Figures 2 and 7, the case body 2 is composed of a resin top shell (first shell) 3 and a back shell (second shell) 4. The top shell 3 and the back shell 4 are rotatably connected with a connecting part 31 as the pivot point (arrow a in Figure 7). The case body 2 is fixed and maintained (locked) in a sealed state by the user operating a known locking mechanism 5 while the outer edges 3a and 4a of the top shell 3 and the back shell 4 are in contact with each other, thereby sealing the internal space S (Figure 7). When the top shell 3 and the back shell 4 are locked, the case body 2 has an external shape that is vertically or horizontally elongated, approximately rectangular (box-shaped). The internal space S is a space formed inside the case body 2 that can accommodate luggage.

[0012] Alternatively, fasteners (zippers) not shown may be formed on the three sides (all around the perimeter) of both the top shell 3 and the back shell 4, and the fasteners may be used to maintain the fixed state of the top shell 3 and the back shell 4.

[0013] In Figures 1, 2, 3, 5, 6, and 7, casters 6 are attached to each of the four corners of the bottom surface of the case body 2. By rotating the multiple casters 6, the user can move the carry case 1 in a predetermined direction.

[0014] In Figures 2 and 3, the top shell 3 is provided with a first handle 7 that is extendable and retractable in the direction of arrow b (Figure 3). The first handle 7 is constructed by attaching a gripping member 9 that extends laterally to the tops of a plurality (two in this embodiment) of telescopic rods 8 that are arranged at predetermined intervals in the lateral direction. The first handle 7 is "gate" shaped.

[0015] A recess 10 is formed at the top of the top shell 3, and the first handle 7, in its retracted state, is stored in this recess 10. The recess 10 is the first storage compartment in which the first handle 7 is stored. By extending the telescopic rod 8, the first handle 7 extends above the case body 2 (Figure 3). The user typically moves the carry case 1 by gripping the first handle 7 with the top shell 3 facing them.

[0016] In Figures 2 and 3, a second handle 11 is provided on the upper surface of the back shell 4 so as to be movable vertically relative to the back shell 4 (arrow b shown in Figure 3). The second handle 11 has a roughly T-shape, with a gripping member 13 extending horizontally attached to the top of a single rod 12 extending vertically. A recess 14 is formed in the upper part of the back shell 4, and by moving the rod 12 along the longitudinal direction relative to this recess 14, the second handle 11 is stored in or pulled out of the recess 14 (arrow b shown in Figure 2). The recess 14 is a second storage compartment in which the second handle 11 is stored.

[0017] Figure 3 shows the first handle 7 and the second handle 11 extended to their maximum upward positions relative to the case body 2. In this state, the height position H1 of the gripping member 13 of the second handle 11 is set to be lower than the height position H2 of the gripping member 9 of the first handle 7 (Figure 6). In other words, the rod 12 constituting the second handle 11 is set to be shorter than the telescopic rod 8 constituting the first handle 7. The reason why the vertical lengths of the first handle 7 and the second handle 11 are different will be explained later. Note that the first handle 7 may be provided on the back shell 4 side and the second handle 11 on the top shell 3 side.

[0018] As shown in FIGS. 1 and 5, on the upper surface side of the case body 2, a seat member 15 for supporting the occupant P from the buttocks to the back is detachably attached via a first handle 7 and a second handle 11. As the material of the seat member 15, a material excellent in flexibility and softness, such as polyester, polyurethane, silicon, cotton, etc., is selected.

[0019] FIG. 4(a) is a developed perspective view of the front side of the seat member 15, and FIG. 4(b) is a developed perspective view of the back side of the seat member 15. The seat member 15 includes a hip receiving portion 16 having a seating surface, a backrest portion 17 formed behind the hip receiving portion 16, and a belly receiving portion 18 formed in front of the hip receiving portion 16.

[0020] At the boundary position between the hip receiving portion 16 and the backrest portion 17, a notch portion 19 in a state of being cut out from both sides is formed. Similarly, at the boundary position between the hip receiving portion 16 and the belly receiving portion 18, a notch portion 20 in a state of being cut out from both sides is formed. The notch portion 20 is formed within a range corresponding to the occupant P's thigh. The notch portion 20 serves as an insertion space into which the occupant P's thigh is inserted.

[0021] Slits 21 are formed on each of both sides of the backrest portion 17, and a belt 22 is inserted into the slits 21. Male buckles 23 as fastening means are fixed to both ends of the belt 22. In FIG. 4(b), at a predetermined position of the belt 22 on the back side of the seat member 15, two band members 24 are fixed at substantially the same interval as the two telescopic rods 8 constituting the first handle 7. Both ends of the band member 24 are free ends, and male fasteners and female fasteners (not shown) are provided at each of both ends. The central portion of the band member 24 is fixed to the belt 22.

[0022] As shown in FIG. 5, the interval between the two slits 21 formed in the backrest portion 17 is larger than the interval between the two telescopic rods 8 constituting the first handle 7.

[0023] In Figure 4, slits 25 are formed on each side of the abdominal support portion 18, and a belt 26 is inserted into these slits 25. Female buckles 27 are fixed to both ends of the belt 26 as fastening means. In Figure 4(b), a band member 28 is fixed to the back side of the sheet member 15 at approximately the center of the belt 26. Both ends of the band member 28 are free ends, and male and female hook fasteners (not shown) are provided at each end. The central part of the band member 28 is fixed to the belt 26.

[0024] To attach the sheet member 15 to the first handle 7 and the second handle 11, first, the first handle 7 and the second handle 11 are raised to their maximum height relative to the case body 2 (Figure 3). Next, the band member 24 is wrapped around and secured to each of the two telescopic rods 8 that make up the first handle 7 via male and female fasteners (Figures 5 and 6). Furthermore, the band member 28 is wrapped around and secured to the rod 12 that makes up the second handle 11 via male and female fasteners (Figures 5 and 6). As a result, the sheet member 15 is attached to the first handle 7 and the second handle 11 (and thus to the case body 2) on the upper side of the case body 2.

[0025] Next, we will explain how to place the passenger P into the carry case 1. With the seat member 15 attached to the first handle 7 and the second handle 11 as described above, the passenger P is seated on the buttock support portion 16 facing the second handle 11 (Figures 1 and 6). At this time, the passenger P's thighs are aligned with the notch portion 20 (insertion space). The second handle 11 is roughly T-shaped, and the connecting portion 30 (Figure 4) that connects the buttock support portion 16 and the abdominal support portion 18 of the seat member 15 is positioned opposite the rod 12 that constitutes the second handle 11. Therefore, the second handle 11 does not interfere with the passenger P's thighs, and the passenger P can comfortably face their legs towards the back shell 4.

[0026] Once the passenger P is seated, the corresponding male buckle 23 and female buckle 27 are fastened together. This covers the passenger P from the sides with the belts 22 and 26, preventing them from falling out of the carry case 1 (Figures 1 and 6). This completes the method for placing the passenger P into the carry case 1.

[0027] Since the backrest 17 is supported from the rear by two telescopic rods 8, the backrest 17 does not tilt backward even when a passenger P sitting on the seat member 15 leans back against it. Furthermore, since the second handle 11 (grip member 13) is positioned lower than the first handle 7, the passenger P can grip the second handle 11 (grip member 13) in a comfortable posture with both elbows bent in front of their chest. In this way, the passenger P can assume a posture where they face their legs towards the back shell 4 and grip the second handle 11 while leaning their back against the backrest 17. Therefore, even when the user grips the first handle 7 and moves the carry case 1, the passenger P can maintain a stable posture.

[0028] When placing the carry-on case on the luggage rack of a train or airplane, the first handle 7 and the second handle 11 are stored in the recesses 10 and 14, respectively (Figure 2). With the handles stored, the carry-on case 1 is roughly rectangular, and since the handles (grips) do not protrude outward, it is possible to prevent it from being bulky when placed on the luggage rack of a car or train. In addition, since there is no need to shape the case body 2 into an L-shape, the amount of luggage that can be stored can be ensured.

[0029] As described above, the carry case 1 in this embodiment comprises a case body 2 comprising a first shell (top shell 3) and a second shell (back shell 4), a first gripping portion (first handle 7) provided on either the first shell or the second shell, a second gripping portion (second handle 11) provided on either the first shell or the second shell that does not have the first gripping portion, and a seat portion (seat member 15) that is detachably attached to the first gripping portion and the second gripping portion and on which a passenger P can sit.

[0030] Furthermore, the second gripping part (second handle 11) is for the passenger P to grip while seated in the seat (seat member 15), and when the first gripping part (first handle 7) and the second gripping part are raised to their highest positions relative to the case body 2, the second gripping part is at a lower height than the first gripping part.

[0031] The carry case of this disclosure is not limited to the embodiments described herein, and design modifications may be made without departing from the spirit of the invention. For example, the first handle 7 does not have to be retractable. Also, the first handle 7 may be T-shaped, but a gate-shaped design as in this embodiment allows for more stable support of the backrest 17.

[0032] Furthermore, the second handle 11 may be configured to be detachable from the case body 2. More specifically, a male thread may be formed on the lower end of the rod 12 that constitutes the second handle 11, and a female thread may be formed on the upper surface of the back shell 4 (the male and female threads may be reversed). Then, the second handle 11 may be attached to the case body 2 by screwing the male thread of the rod 12 into the female thread of the back shell 4.

[0033] In other words, the second gripping portion (second handle 11) is detachably attached to the upper surface of the case body 2, and when the first gripping portion (first handle 7) is raised to its highest position relative to the case body 2, and the second gripping portion is also attached to the case body 2, the second gripping portion is at a lower height than the first gripping portion. This configuration eliminates the need to provide a recess 14 in the back shell 4 for storing the second handle 11, thereby increasing the luggage capacity. [Industrial applicability]

[0034] This product provides a carry-on case that ensures ample storage capacity for luggage while preventing bulkiness when placed on the cargo bed, and allows passengers to sit in a stable position. [Explanation of Symbols]
