Description

Technical Field

[0001] The present invention relates to a suitcase.

Background Art

[0002] Since a suitcase can be carried with a light force even for heavy luggage by casters, it is very useful when moving. When taking out luggage from such a suitcase, usually, it is necessary to lay the suitcase body horizontally and open the case, which becomes a large-scale operation.

[0003] Therefore, a front-opening type suitcase that allows loading and unloading of luggage in a standing state has been proposed (see Patent Document 1 below). The front-opening type suitcase can be taken out immediately from the front pocket such as a personal computer or small items without taking up space at an airport or in a narrow aircraft cabin, which is very convenient.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in a front-opening type suitcase, the opening lid on the front-opening side (front side) has a structure that is opened and closed by a slide fastener. In this case, when opening and closing the opening lid, it is necessary to use both hands because the slide fastener is slid while holding the suitcase. Therefore, it is difficult to easily open and close the opening lid with one hand.

[0006] An object of the present invention is to provide a suitcase in which the front-opening lid can be easily opened and closed, and the opening lid is difficult to open and has high airtightness in a closed state. [Means for solving the problem]

[0007] (1) A suitcase according to one embodiment for achieving the above objective comprises a first half-slotted storage section and a second half-slotted storage section adjacent to the outer thickness of the first storage section and capable of opening, wherein the opening edge of the first storage section and the opening edge of the second storage section are connected by a first slide fastener, The second storage section comprises a second opening which is smaller than the first opening of the first storage section, and an upper lid which can be opened and closed relative to the second opening. The upper lid is curved upwards toward the first storage compartment and notched to form gussets on both sides, and is attached to the second opening so as to be openable and closable. A first sealing member is attached to the circumferential edge of the opening of the second opening, and a second sealing member is attached to the circumferential edge of the opening of the upper cover, The upper cover portion is characterized in that at least a second sealing member is joined to the peripheral edge of the opening of the second opening. (2) In a suitcase according to another embodiment, it is preferable that the shape of the opening edge of the upper lid portion matches the shape of the opening edge of the second opening. (3) In a suitcase according to another embodiment, preferably, in the second opening, a recess extends circumferentially from the upper edge of the side surface of the second storage section on the first storage section side, and further, the inner peripheral edge of the opening extends circumferentially toward the outer side in the thickness direction of the second storage section, and the second sealing member is fitted into the recess when the upper lid is closed. (4) In a suitcase according to another embodiment, it is preferable that the height of the inner wall of the recess on the second storage compartment side is higher than the height of the inner wall of the recess on the first storage compartment side. (5) In a suitcase according to another embodiment, it is preferable that a recess extends circumferentially from the upper edge of the rear side surface of the second storage compartment, and that the outer inner wall of the recess extends upward circumferentially to a point where it is higher than the inner wall of the inner surface of the recess, and that when the upper lid is closed, the first sealing member of the upper lid is fitted into the recess. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a suitcase with a front-opening lid that can be easily opened and closed, and which has a high degree of airtightness, with the lid being difficult to open when closed. [Brief explanation of the drawing]

[0011] Here, in the suitcase 1, when the user pulls and moves the suitcase 1, the upper side is the upper side, the lower side is the lower side, the side where the top handle 20 described later is formed is the back side (inner side, rear side), and the side where the upper lid portion 7 described later is formed is the front side (outer side, front side). The direction orthogonal to both the vertical direction and the front-back direction is the left-right direction. In each drawing, the same reference numerals are assigned to the same elements.

[0012] As shown in FIG. 1, the suitcase 1 according to the embodiment includes a vertically long first storage portion (back portion) 3 that is split in half, and a second storage portion (front portion) 5 that is split in half and to which the upper lid portion 7 is attached so as to be openable and closable. Between the first storage portion 3 and the second storage portion 5, a partition surface portion 11 having a substantially rectangular planar shape that defines (divides) the first storage portion 3 and the second storage portion 12 is provided.

[0013] A connecting tool (not shown) such as a hinge is provided on one side of the first storage portion 3 to make the first storage portion 3 rotatable. The first slide fasteners 13 are attached to the other three sides to enable opening and closing of the first opening 15 of the first storage portion 3. Moving casters 21 are attached to the four bottom corners of the vertically placed suitcase 1. The first storage portion 3 and the second storage portion 5 are made of a hard synthetic resin material having elasticity, for example, a polycarbonate resin material.

[0014] (Structure of the first storage portion 3) The first slide fastener 13 and the second slide fastener 23 are attached to three sides of the first storage portion 3 excluding the lower side. The first slide fastener 13 is formed substantially parallel to the second slide fastener 23 described later at a predetermined interval along the first opening 15. When the first slide fastener 13 is opened, the inside of the first storage portion 3 is exposed. The second slide fastener 23 is formed along the first opening 15. When the second slide fastener 23 is opened, a depth adjustment groove (not shown) for expanding the depth in the width direction of the first storage portion 3 is exposed.

[0015] In the first storage compartment 3, a handle recess 18 is provided in the upper gusset portion 16, and a top handle 20 for pulling the suitcase 1 is retractably housed in the handle recess 18. The telescopic legs (not shown) of the top handle 20 are attached vertically to the inner wall surface of the first storage compartment 3. In addition, a handle portion 17 for carrying the suitcase 1 is provided in the first storage compartment 3 between the top handle 20 and the first opening 15.

[0016] (Structure of the second storage compartment 5) The second storage section 5 is constructed by attaching the upper lid 7 to a second opening 25, which is formed by cutting out a curved section on the upper side towards the first storage section 3, starting from approximately one-third of the way up from both ends of the upper edge, to create gussets on both sides. The degree of curvature can be adjusted so that the gusset width gradually narrows from both ends of the upper edge of the second storage section 5, or the gusset width can be formed by cutting out a straight line without curvature.

[0017] In the upper lid portion 7, the shape of the opening periphery portion 51 of the upper lid portion 7 matches the shape of the opening periphery portion 53 of the second opening 25. A first lock portion (first locking portion) 31 for locking the pull tab of the first slide fastener 13 is provided on one side of the second storage portion 5 near the second opening 25. A second lock portion (second locking portion) 33 for locking the upper lid portion 7 after it has been closed relative to the second opening 25 is provided on the surface near the top edge of the upper lid portion 7. A lock receiving portion 34 is provided on the top surface of the second opening 25 of the second storage portion 5, and locking is performed by the second lock portion 33 and the lock receiving portion 34. The locking mechanism is performed by providing a dial, slide button, hook portion, etc. on the second lock portion 33 and inserting the hook portion into the insertion slot of the lock receiving portion 34, but a detailed explanation is omitted as this is publicly known.

[0018] The opening height of the second opening 25 is preferably about one-third from the top, but it may be at one-quarter or even narrower. A first sealing member 47 is attached to the circumferential edge 53 of the opening of the second opening 25. A second sealing member 43 is attached to the circumferential edge 51 of the opening of the upper cover 7. The first sealing member 47 and the second sealing member 43 are made from synthetic resin materials such as polyester and nylon, but are not limited to these as long as they are flexible and have good adhesion and sealing (packing) function when the sealing members are joined together.

[0019] The upper cover portion 7 is connected to the second opening 25 in a manner that allows it to be opened and closed, via a connecting member (for example, a hinge) 36 provided on the lower edge of the upper cover portion 7 and a part of the lower edge of the second opening 25.

[0020] (Shape of the opening periphery of the second opening and the joining method of the upper lid) [Examples] As shown in Figure 3, the second opening is formed by folding a predetermined length downward from the upper edge of the rear side surface 71 of the second storage section 5 to form a protrusion 72, and then extending horizontally toward the front side, the inner peripheral edge 77 of the opening is extended along the circumferential direction, and the first sealing member 47 is joined (fixed) to the inner peripheral edge 77 of the opening so as to cover the inner peripheral edge 77. On the other hand, when the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 engages with the protrusion 72, and the upper lid 7 closes the second opening 25 of the second storage section 5. With the above configuration, the second sealing member 43 of the upper lid 7 firmly engages with the protrusion 72 of the second storage section 5, thereby improving airtightness and significantly suppressing the problem of the upper lid 7 opening after being closed. Moreover, the above effects can be achieved with a simple configuration (a structure that only requires bending the protrusion 72 once).

[0021] [Example 1] As shown in Figure 4, the second opening 25 has a recess 65 extending circumferentially from the upper edge of the rear side surface 61 of the second storage section 5, with the inner wall 66 on the front side of the recess 65 extending upward circumferentially until it is higher than the inner wall 64 on the rear side of the recess 65, and the first sealing member 47 is joined (fixed) to cover the upper end of the inner wall 66. On the other hand, when the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 fits into the recess 65, and the upper lid 7 closes the second opening 25 of the second storage section 5. With the above configuration, the first sealing member 47 of the upper lid portion 7 is fitted into the recess 65 and also engages with the first sealing member 47 of the second storage portion 5, thereby enhancing the packing effect and improving airtightness, and significantly suppressing the upper lid portion 7 from opening after being closed.

[0022] [Differentiation 2] As shown in Figure 5, the second opening 25 has a recess 95 extending circumferentially from the upper edge 93 of the rear side surface 91 of the second storage section 5, and further extending circumferentially from the inner peripheral edge 97 of the opening toward the front side of the second storage section 5. When the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 fits into the recess 95, and the upper lid 7 closes the second opening 25 of the second storage section 5. In other words, the second sealing member 43 is joined (fixed) to the inner peripheral edge 97 of the opening so as to cover it. With the above configuration, the second sealing member 43 of the upper lid 7 is securely fitted into the recess 95, creating a so-called packing state, which enhances airtightness and significantly reduces the likelihood of the upper lid 7 opening after being closed.

[0023] [Difference 3] Modification 3 is identical to Modification 2 except for the shape of the recess, so only the differences will be explained below. As shown in Figure 6, the recess 85 extends circumferentially from the upper edge of the rear side surface 81 of the second storage section 5, but the height (vertical height) of the inner wall on the front side (outside) of the recess 85 is higher than that of Modification 2. With the above configuration, the second sealing member 43 of the upper lid portion 7 is securely fitted into the deeper recess 85, thereby improving airtightness and further suppressing the problem of the upper lid portion 7 opening after being closed.

[0024] [Differentiation Example 4] Modification 4 is the same as Modification 3 except for the following differences, so only the differences will be explained. As shown in Figure 7, the second opening has a recess 105 that extends circumferentially from the upper edge of the rear side surface 71 of the second storage section 5, and the inner wall 106 on the front side of the recess 105 extends diagonally upward along the circumferential direction until it is higher than the inner wall 104 on the rear side of the recess 105. With the above configuration, the second sealing member 43 of the upper lid portion 7 fits into the recess 105 and also engages with the first sealing member 47 of the second storage portion 5, thereby enhancing the packing effect and improving airtightness, and further suppressing the situation in which the upper lid portion 7 opens after being closed.

[0025] [Difference 5] As shown in Figure 8, the second opening 25 has a horizontal section 112 that extends horizontally and circumferentially from the upper edge of the rear side surface 111 of the second storage section 5 toward the front for a length approximately the same as the thickness of the second sealing member 43 of the opening periphery 51, and a front wall 116 that extends upward circumferentially. The front wall 116 extends upward by the length of the short side of the second sealing member 43 (the height (width) direction of the seal), then extends diagonally upward toward the rear (forming a diagonal section 118), and then extends vertically upward. The first sealing member 47 is joined (fixed) to the opening periphery 117 so as to cover the opening periphery 117. On the other hand, when the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 is fitted between the horizontal section 112 and the diagonal section 118, and the upper lid 7 closes the second opening 25 of the second storage section 5. Furthermore, the rear side surface 111 of the second storage compartment 5 and the rear side of the opening edge 51 of the upper lid 7 are flush (there is no step or difference). With the above configuration, the second sealing member 43 of the upper lid portion 7 is fitted between the horizontal portion 112 and the slanted portion 118 and also engages with the first sealing member 47 of the second storage portion 5. This enhances the packing effect, further improves airtightness, and more significantly suppresses the upper lid portion 7 from opening after being closed.

[0026] [Modification 6] As shown in Figure 9, the second opening 25 has a slanted portion 124 extending circumferentially downward diagonally toward the front from the upper edge 122 of the rear side surface 121 of the second storage section 5, a first horizontal portion 125 extending circumferentially toward the front, and an inner peripheral edge portion 127 extending vertically upward along the circumferential direction. The slanted portion 124, the first horizontal portion, and the inner peripheral edge portion 127 form a recess 123. The height of the inner peripheral edge portion 127 of the recess 123 is higher than the height (vertical height) of the slanted portion 124 on the rear side. Furthermore, a second horizontal portion 128 extends horizontally from the inner peripheral edge portion 127 toward the front of the second storage section 5. On the other hand, when the upper lid portion 7 is closed, the second sealing member 43 of the upper lid portion 7 fits into the recess 123, and the upper lid portion 7 closes the second opening 25 of the second storage section 5. With the above configuration, the second sealing member 43 of the upper lid 7 is fitted into the recess 123 which is deeper and widens upward, so that the upper lid 7 can be opened and closed reliably and the problem of the upper lid 7 opening after being closed can be further suppressed.

[0027] [Difference 7] As shown in Figure 10, the second opening 25 has a first horizontal section 135 extending circumferentially from the upper edge 132 of the rear side surface 131 of the second storage section 5 toward the front side of the second storage section 5, and an inner peripheral edge section 127 extending vertically upward toward the front side of the opening. Furthermore, a second horizontal section 138 extends horizontally from the upper edge of the inner peripheral edge section 137 toward the front side of the second storage section 5. On the other hand, when the upper lid section 7 is closed, the second sealing member 43 of the upper lid section 7 is fitted between the upper side of the first horizontal section 135 and the rear side surface of the inner peripheral edge section 137, and the upper lid section 7 closes the second opening 25 of the second storage section 5. In addition, the rear side surface 131 of the second storage section 5 and the rear side of the opening peripheral edge section 51 of the upper lid section 7 are flush (there is no step). With the above configuration, the second sealing member 43 of the upper lid portion 7 is fitted between the upper side of the first horizontal portion 135 and the rear side surface of the inner peripheral edge portion 137 of the opening with a simple structure, so that the upper lid portion 7 can be reliably opened and closed with a simple structure, and the condition in which the upper lid portion 7 opens after being closed can be suppressed.

[0028] [Differentiation 8] As shown in Figure 11, the second opening 25 has a horizontal section 145 extending circumferentially from the upper edge 142 of the rear side surface 141 of the second storage section 5 toward the front side of the second storage section 5, and an inner peripheral edge section 147 extending vertically upward along the circumferential direction. When the upper lid section 7 is closed, the second sealing member 43 of the upper lid section 7 is fitted between the upper side of the horizontal section 145 and the rear side surface of the inner peripheral edge section 147, and the upper lid section 7 closes the second opening 25 of the second storage section 5. The rear side surface 141 of the second storage section 5 and the rear side of the opening peripheral edge section 51 of the upper lid section 7 are flush (there is no step). With the above configuration, the second sealing member 43 of the upper lid portion 7 is fitted between the upper side of the horizontal portion 145 and the rear side surface of the inner peripheral edge portion 147 of the opening with a simple structure, so that the upper lid portion 7 can be reliably opened and closed with a simple structure, and the condition in which the upper lid portion 7 opens after being closed can be suppressed.

[0029] [Modification 9] As shown in Figure 12, the second opening 25 has a horizontal portion 155 extending circumferentially from the upper edge 152 of the rear side surface 151 of the second storage section 5 toward the front side of the second storage section 5, and an inner peripheral edge portion 157 extending circumferentially in a diagonal upward direction toward the rear side. The opening peripheral edge 153 of the upper lid portion 7 is composed of an opening peripheral edge portion (vertical portion) 51 extending vertically downward from above, and a bent portion 154 extending diagonally downward toward the front side from the opening peripheral edge portion (vertical portion) 51. When the upper lid portion 7 is closed, the second sealing member 43 of the upper lid portion 7 is fitted diagonally between the upper side of the horizontal portion 155 and the rear side surface of the inner peripheral edge portion 157, and the upper lid portion 7 closes the second opening 25 of the second storage section 5. Furthermore, the rear side surface 151 of the second storage section 5 and the rear side of the vertical section 51 that constitutes the opening periphery 153 of the upper lid section 7 are flush (there is no step or difference). With the above configuration, the second sealing member 43 of the upper lid portion 7 (the second sealing member 43 provided on the bent portion 154 formed in the diagonal front direction) is fitted diagonally between the upper side of the horizontal portion 155 and the inner peripheral edge portion 157 of the opening that is bent diagonally upward on the rear side, with a simple structure. As a result, the upper lid portion 7 can be reliably opened and closed with a simple structure, and the problem of the upper lid portion 7 opening after being closed can be suppressed to a greater extent.

[0030] [Example 10] As shown in Figure 13, the second opening 25 has a horizontal portion 165 extending circumferentially from the upper edge of the rear side surface 161 of the second storage section 5 toward the front of the second storage section 5, and an inner peripheral edge portion 167 extending vertically upward along the circumferential direction. The inner peripheral edge portion 167 is composed of a vertical portion 166 extending vertically upward along the circumferential direction, a recess 168 extending circumferentially with a concave shape on the rear side, and a horizontal portion 170 extending circumferentially toward the front side. The opening peripheral edge portion 160 of the upper lid portion 7 is composed of a first vertical portion 162 extending vertically downward from above, a recess 164 with a concave shape on the front side, a convex portion 163 with a convex shape on the front side, and a second vertical portion 172 extending vertically downward from the convex portion 163. On the other hand, when the upper lid portion 7 is closed, the second sealing member 43 of the upper lid portion 7 is fitted diagonally between the upper side of the horizontal portion 165 and the rear side surface of the inner peripheral edge portion 167 of the opening, and the convex portion 163 and concave portion 168 are fitted together, so that the upper lid portion 7 closes the second opening 25 of the second storage portion 5. With the above configuration, the second sealing member 43 of the upper lid portion 7 (the second sealing member 43 provided on the bent portion 154 formed in the diagonal front direction) is fitted between the upper side of the horizontal portion 165 and the inner peripheral edge portion 167 of the opening with a simple structure, and the convex portion 163 and the concave portion 168 are fitted together, so that the upper lid portion 7 can be opened and closed reliably and the situation in which the upper lid portion 7 opens after being closed can be suppressed to a great extent.

[0031] [Example 11] As shown in Figure 14, the second opening 25 has a horizontal section 185 that extends horizontally and circumferentially from the upper edge of the rear side surface 181 of the second storage section 5 toward the rear for a length approximately the same as the thickness of the second sealing member 43 of the opening periphery 51, and a rear wall 187 further extends upward circumferentially. The first sealing member 47 is joined (fixed) to the inner periphery 188 of the opening so as to cover it. On the other hand, when the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 fits between the horizontal section 185 and the rear wall 187, and the upper lid 7 closes the second opening 25 of the second storage section 5. With the above configuration, the second sealing member 43 of the upper lid 7 is fitted between the horizontal portion 185 and the rear wall 187, and also engages with the first sealing member 47 of the second storage portion 5. This enhances the packing effect, further improves airtightness, and more significantly reduces the likelihood of the upper lid 7 opening after being closed.

[0032] [Example 12] As shown in Figure 15, the rear side surface 191 of the second storage section 5 extends vertically, and the first sealing member 47 is joined (fixed) to the upper end of the rear side surface 191. On the other hand, when the upper lid 7 is closed, the second sealing member 43 of the upper lid 7 engages with the first sealing member 47, and the upper lid 7 closes the second opening 25 of the second storage section 5. With the above configuration, the second sealing member 43 of the upper lid 7 engages with the first sealing member 47 on the second storage section 5 side, thereby enhancing the packing effect and improving airtightness, and further suppressing the situation in which the upper lid 7 opens after being closed.

[0033] [effect] The above-described embodiment is a suitcase 1 comprising a halved first storage section 3 and a halved second storage section 5 adjacent to the outer thickness direction of the first storage section 3 and capable of opening, with the opening periphery of the first storage section 3 and the opening periphery 53 of the second storage section 5 connected by a first slide fastener 13, wherein the second storage section 5 comprises a second opening 25 formed smaller than the first opening 15 of the first storage section 3 and an upper lid 7 that can be opened and closed relative to the second opening 25, the upper lid 7 is curved upward toward the first storage section 3 and notched to form gussets on both sides and is attached to the second opening 25 so as to be openable and closable, a first sealing member 47 is attached to the opening periphery 53 of the second opening 25 along the circumferential direction, and a second sealing member 43 is attached to the opening periphery 51 of the upper lid 7 along the circumferential direction, and the upper lid 7 has at least the second sealing member 43 joined to the opening periphery 53 of the second opening 25. Therefore, the second sealing member 43 of the upper lid 7 is securely fitted to the first sealing member 47 of the second storage section 5, creating a so-called packing state, which enhances airtightness and significantly prevents the upper lid 7 from opening after being closed.

[0034] Furthermore, according to this embodiment, the shape of the opening edge 51 of the upper lid 7 matches the shape of the opening edge 53 of the second opening 25. Therefore, when the opening edge 51 of the upper lid 7 and the opening edge 53 of the second opening 25 are joined, they are securely sealed, thereby improving airtightness.

[0035] Furthermore, according to this embodiment, in the second opening 25, a recess 95 extends circumferentially from the upper edge of the side surface of the second storage section 5 on the first storage section 3 side, and an inner peripheral edge portion 97 of the opening extends circumferentially toward the outer side in the thickness direction of the second storage section 5, and the second sealing member 43 is fitted into the recess 95 when the upper lid 7 is closed. Therefore, since the second sealing member 43 of the upper lid 7 is securely fitted into the recess 95, it becomes a so-called packing state, which enhances airtightness and greatly suppresses the upper lid 7 from opening after being closed.

[0036] Furthermore, according to this embodiment, the height of the inner wall of the recess 85 on the second storage section 5 side is higher than the height of the inner wall of the recess 85 on the first storage section 3 side. Therefore, the second sealing member 43 of the upper lid 7 is securely fitted into the deeper recess 85, thereby improving airtightness and further suppressing the problem of the upper lid 7 opening after being closed.

[0037] Furthermore, according to this embodiment, a recess 65 extends circumferentially from the upper edge of the rear side surface of the second storage section 5, and the outer inner wall 66 of the recess 65 extends upward circumferentially until it is higher than the inner wall 64 of the inner surface of the recess 65, so that when the upper lid is closed, the second sealing member 43 of the upper lid 7 fits into the recess 65. Therefore, since the second sealing member 43 of the upper lid 7 fits into the recess 65 and also engages with the first sealing member 47 of the second storage section 5, the effect of the packing is enhanced, the airtightness is further improved, and the condition in which the upper lid 7 opens after being closed can be further suppressed.

[0038] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. [Explanation of Symbols]
