Description

[Technical Field]

[0001] The present invention relates to a pocket that prevents a generally rectangular stored item from falling out. [Background technology]

[0002] Conventionally, to prevent items from falling out when a pocket is turned upside down, a flap is sewn to the top of the pocket opening and fastened with a button or hook-and-loop fastener, or the pocket opening is closed using a zipper. However, this requires the user to open and close the pocket opening every time an item is put in or taken out, which is cumbersome. Therefore, pockets that prevent items from falling out without the need to open and close the pocket opening have been disclosed as prior art (References 1 and 2). Another advantage of these technologies is that they allow greater freedom in pocket design because they do not use flaps or zippers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2013-19079 [Patent Document 2] Utility model registration No. 3217052 Summary of the Invention [Problem to be solved by the invention]

[0004] In Literature 1 and Literature 2, the pockets do not use flaps or zippers on the outside, but instead have a flat-shaped presser foot or a stretchy strip of fabric on the inside, which requires the user to place the presser foot or strip over the contents after inserting them. While this does not impair the freedom of the pocket's appearance, it poses the problem of requiring the same cumbersome operations inside the pocket as conventional pockets. Furthermore, the number of steps required, such as creating a component to hold the contents and sewing it to the pocket, is the same as for conventional pockets with flaps or zippers. This invention was devised to solve the above problems of conventional pockets. It aims to allow smooth insertion and removal of contents and prevent contents from falling out when the pocket is turned upside down, without having to hold the pocket opening by holding an external component or physically holding the contents with an internal component, but only through the structure of the pocket opening itself. [Means for solving the problem]

[0005] This pocket is intended for storing a roughly rectangular item and has a diagonally positioned pocket opening, the length of the pocket opening is longer than the side along which the item is inserted, and the length of the side connecting the intersection of a line extended horizontally from the bottom edge of the pocket opening and a line extended vertically downward from the top edge of the pocket opening and the bottom edge of the pocket opening is shorter than the side along which the item is inserted. The distance from the bottom edge of the pocket opening to the bottom edge is shorter than the side of the item, and the distance from the bottom edge of the pocket opening to the top edge of the pocket opening is longer than the side of the item. When implemented as a slit pocket, the pocket opening is trapezoidal in shape.

[0006] If you try to insert an object vertically into the pocket, it will not fit inside, but if you align the edge of the object you are trying to insert parallel to the pocket opening, it will fit inside the pocket opening. After the bottom corner of the object touches the bottom edge of the pocket fabric, shift the bottom corner of the object toward the bottom edge of the pocket opening, and then rotate the diagonal corner around the bottom corner toward the top corner of the pocket opening, and the object will fit smoothly into the pocket. When the object fits into the pocket, part of one of the top corners of the object will protrude from the pocket opening.

[0007] When removing an item from a pocket, grab the item that is partially sticking out of the pocket opening and perform the reverse of the action you took to put it away, allowing you to remove the item smoothly. On the other hand, turning the pocket upside down without performing the above action will prevent the item from flying out of the pocket opening. Also, when using a cut pocket, making the pocket opening trapezoidal will further enhance the ability to prevent items from flying out. [Effects of the Invention]

[0008] The present invention achieves the following effects: It has the function of preventing stored items from falling out of the pocket, even when the pocket is turned upside down, without using a means for opening and closing the pocket opening with a flap or zipper on the outside of the pocket, or a means for holding items in place with a plush retaining cloth or stretchy strip of cloth on the inside of the pocket. It also eliminates the hassle of opening and closing the pocket opening or covering and removing components inside the pocket over the stored items every time an item is taken in or out. Furthermore, since no special materials or additional processes are required for production, the present invention does not increase production costs. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in detail below with reference to the embodiments shown in the drawings. Figure 1 is a front view showing an example of a pocket opening (1) structure and an example of an object (4) to be stored in a slit pocket, which is designed to facilitate right-handed people's access to and removal of the object (4) when the short side (5-1) of the object (4) is stored in the pocket lining (6). If the intersection of a line extending horizontally from corner (1c) of pocket opening (1) and a line extending vertically from corner (1d) is taken as point (2), a right-angled triangle is formed by connecting corner (1d) and corner (1c) of pocket opening (1) to point (2). Side (3-1) connecting corner (1d) and corner (1c) of pocket opening (1) is the hypotenuse of the right-angled triangle, and side (3-2) connecting corner (1c) of pocket opening (1) and point (2) is the adjacent side of the right-angled triangle. The size and angle of the pocket opening (1) are set so that the hypotenuse (3-1) of the right triangle is longer than the short side (5-1) of the storage object (4), and the major side (3-2) of the right triangle is shorter than the short side (5-1) of the storage object (4). The pocket opening (1) is also trapezoidal. The distance from the bottom side (6-1) of the pocket lining (6) to the corner (1c) of the pocket opening (1) is shorter than the long side (5-2) of the storage object, and the distance from the bottom side (6-1) of the pocket lining (6) to the corner (1d) of the pocket opening (1) is longer than the long side (5-2) of the storage object (4). This is the structure characterized by the above.

[0011] Figure 2 is a front view of the pocket opening (1) of Figure 1 when attempting to insert the short side (5-1) of the storage object (4) perpendicularly. Since the adjacent side (3-2) of the right triangle is shorter than the short side (5-1) of the storage object (4), the storage object (4) cannot be inserted into the pocket opening (1).

[0012] Figure 3 is a front view of the pocket opening (1) of Figure 1 when inserting the storage object (4) with its short side (5-1) parallel to the pocket opening (1). Because the hypotenuse (3-1) of the right triangle is longer than the short side (5-1) of the storage object (4), the storage object (4) can be inserted into the pocket opening (1).

[0013] After the bottom corner (4c) of the object (4) hits the bottom edge (6-1) of the pocket lining (6), the corner (4c) of the object (4) is shifted to the right while the diagonal corner (4a) is rotated counterclockwise around the corner (4c) as an axis, and the object (4) is smoothly stored inside the pocket lining (6). This series of steps is shown in Figures 4 and 5.

[0014] When the storage object (4) is placed in the pocket lining (6), the corner portion (4b) of the storage object (4) protrudes from the pocket opening (1). When removing the storage object (4), grasp the corner portion (4b) of the storage object (4) that is partially protruding from the pocket opening (1) and perform the reverse action of the insertion to smoothly remove the storage object (4) from the pocket opening (1).

[0015] On the other hand, even if the pocket is turned upside down without performing the above steps, the object (4) will not fly out from the pocket opening (1). When the pocket is turned upside down after storing the object (4) in the pocket lining (6), the object (4) is likely to fly out from the pocket opening (1) when the top edge of the pocket lining (6) is horizontal as shown in Figure 6 and when the pocket opening (1) is horizontal as shown in Figure 7. In the case of Figure 6, the side (3-2) of the right triangle is shorter than the short side (5-1) of the object (4), so the corner (4a) of the object (4) is held down by the corner (1d) of the pocket opening (1) and will not fly out from the pocket opening (1). Furthermore, even if the pocket is turned upside down and shaken vigorously, resulting in the state shown in Figure 7, the side connecting corner (1a) and corner (1b) of the trapezoidal pocket opening (1), which forms the upper base of the pocket opening (1), is shorter than the short side (5-1) of the stored object (4), so corner (4a) of the stored object (4) is held down by corner (1a) of the pocket opening (1) and will not fly out of the pocket opening (1).

[0016] With the above-described structure, the present invention realizes that the storage object (4) can be smoothly put in and taken out of the pocket, and that the storage object (4) does not jump out of the pocket opening (1) even when the pocket is turned upside down.

[0017] Figure 8 is a front view showing an example of a pocket opening structure and storage object for an outer pocket to facilitate easy access for right-handed people to store and retrieve items (4). The outer pocket (7) is sewn to the product body with stitches along a line connecting corners (7b), (7a), (7e), (7d), and (7c) of the outer pocket (7). A bar stitch (10) is applied diagonally downward from corner (7b) to the inside left of the pocket. This creates the pocket opening on the edge connecting corners (7b) and (7c) of the outer pocket (7). If the intersection of a line extending horizontally from corner (7c) of the outer pocket (7) and a line extending vertically from corner (7b) is taken as point (8), a right-angled triangle is formed by connecting corners (7b) and (7c) of the outer pocket (7) to point (8). The side (9-1) connecting the corners (7b) and (7c) of the pocket opening (7) forms the hypotenuse of a right triangle, and the side (9-2) connecting the corner (7c) of the outer pocket (7) and point (8) forms the front side of the right triangle. The size and angle of the pocket are set so that the hypotenuse (9-1) of the right triangle is longer than the short side (5-1) of the object (4) to be stored, and the front side (9-2) of the right triangle is shorter than the short side (5-1) of the object (4). Furthermore, the distance from the base (7-1) of the outer pocket (7) to the corner (7c) of the outer pocket (7) is shorter than the long side (5-2) of the object (4), and the distance from the bottom (6-1) of the pocket to the corner (7b) of the outer pocket (7) is longer than the long side (5-2) of the object (4) to be stored. This structure is characterized by the above.

[0018] It is also possible to implement a shape in which the long side (5-2) of the storage object (4) is inserted into the pocket opening (101) as shown in Figure 9. If the intersection of a line extended horizontally from corner (101c) of the pocket opening (101) and a line extended vertically from corner (101d) is taken as point (102), a right-angled triangle is formed by connecting corner (101d) and corner (101c) of the pocket opening (101) with point (102). Side (103-1) connecting corner (101d) and corner (101c) of the pocket opening (101) is the hypotenuse of the right-angled triangle, and side (103-2) connecting corner (101c) of the pocket opening (101) and point (102) is the adjacent side of the right-angled triangle. The size and angle of the pocket opening (101) are set so that the hypotenuse (103-1) of the right triangle is longer than the long side (5-2) of the storage object (4), and the minor side (103-2) of the right triangle is shorter than the long side (5-2) of the storage object (4). The pocket opening (101) is trapezoidal. The distance from the bottom side (106-1) of the pocket lining (106) to the corner (101c) of the pocket opening (101) is shorter than the short side (5-1) of the storage object, and the distance from the bottom side (106-1) of the pocket lining (106) to the corner (101d) of the pocket opening (101) is longer than the short side (5-1) of the storage object (4). This is the structure characterized by the above.

[0019] By reversing the left and right sides of each pocket shown in the previous diagrams, left-handed people can It is also possible to implement a specification that makes it easy to take in and out the storage object (4).

[0020] The present invention is effective for all roughly rectangular storage objects, but since the shape and size of the pocket opening required to make the present invention effective varies depending on the size of the storage object, its use in mass-produced products is limited to storage objects of a standard size. The most effective example of its use is pockets for storing credit cards, which are standardized in size by international standards, and various cards whose sizes conform to credit card standards. In addition, pockets for storing credit cards are products that are produced in large quantities worldwide, such as wallets, smartphone cases, and card cases, The effect can be said to be significant.
