Abstract
Description
Technical Field
[0002]
[0001] The present invention relates to a pocket, which is a small bag.
Background Art
[0002] A pocket is a small bag and is an item that is also assumed to be carried by hand or on the shoulder with a string (strap).
Summary of the Invention
Problems to be Solved by the Invention
[0003] Depending on the situation, various gripping forms such as carrying by hand or on the shoulder are conceivable for the pocket. Also, since it is a bag, it is assumed that items are put inside and carried, but it is inconvenient if the lid is easily opened and closed and accidentally opens.
[0004] In view of the above, an object of the present invention is to provide a pocket that can cope with various ways of carrying, preferably can be easily opened and closed, and is not easily opened and closed accidentally.
Means for Solving the Problems
[0005] As a result of intensive efforts, the present inventor has completed the following invention. The pouch of this invention comprises a bag body with an opening at the top, at least two loop-shaped tabs fixed to both sides of the bag body, and two or more beads and two or more strings of different lengths detachably attached to the bag body. The beads are sized so as not to pass through the loops of the tabs and have through holes. The two strings can pass through the through holes. When the beads are attached to the bag, the two strings pass through the through holes of the beads from above, forming knots in the strings below the beads, and the knots are sized so as not to pass through the through holes of the beads. As a result, the ends of the strings are fixed to the beads by the knots. With this fixing, the beads are positioned between the loops formed by the tabs and the knots of the strings.
[0006] Preferably, the opening at the top of the pouch is configured to be openable and closable by a spring clasp. The spring clasp consists of two leaf springs attached near the opening at the top of the pouch and two hinges connecting the two leaf springs at both ends. [Effects of the Invention]
[0007] According to this invention, two strings of different lengths function as straps for carrying by hand or over the shoulder, allowing for multiple carrying methods. Furthermore, by removing the strings and beads, this pouch can also be used as a so-called inner pouch. Preferably, since the opening is made of a spring clasp, it can be opened and closed with little force and is less likely to open or close unintentionally. [Brief explanation of the drawing]
[0008] [Figure 1] This is a schematic external view of the pouch of the present invention. [Figure 2] This is a schematic diagram of the pouch with the beads and string removed. [Figure 3] This is a schematic external view of the pouch in its open state. [Modes for carrying out the invention]
[0009] The present invention will be described in detail with due reference to the drawings as appropriate. However, the present invention is not limited to the illustrated embodiments, and the drawings may emphasize characteristic parts of the invention, so the accuracy of the scale in each part of the drawings is not necessarily guaranteed.
[0010] Figure 1 is a schematic external view of the pouch. The pouch comprises a bag body and at least two loop-shaped tabs.
[0011] The bag body 101 has an opening at the top. The material of the bag body is not particularly limited and may be a fabric made of cloth or synthetic fibers. In this invention, the direction of the opening is defined as "top," and the opposite direction is defined as "bottom." The part perpendicular to the top and bottom is called the "side."
[0012] Tabs 111 and 112 are provided on the sides of the bag body. Preferably, the bag body 101 and the tabs 111 and 112 are made of the same material. More preferably, the bag body 101 and the tabs 111 and 112 are made of the same fabric, and the tabs 111 and 112 are sewn to the bag body 101.
[0013] Each of the loops formed by tabs 111 and 112 has at least two strings 131 and 141 threaded through it. Each string 131 and 141 passes through tabs 111 and 121 on both sides of the bag body, functioning as a shoulder strap or hand strap.
[0014] The pouch is preferably equipped with detachable beads 121 and 122. The beads 121 and 122 are positioned on the underside of the tabs 111 and 121. The beads 121 and 122 are too large to pass through the loops of the tabs 111 and 121.
[0015] Beads 121 and 122 have through holes through which strings 131 and 141 can be passed. There are no particular limitations on the material of the beads; for example, wooden or wood-grain beads can be used from a design perspective.
[0016] The strings 131 and 141 pass through the holes of beads 121 and 122 from above, and knots 151 and 152 are formed on the underside of the strings 131 and 141. The knots 151 and 152 of the strings 131 and 141 are formed to a size that prevents them from passing through the holes of beads 121 and 122. As a result, the ends of the strings 131 and 141 are fixed to beads 121 and 122 by the knots 151 and 152, and since the beads 121 and 122 cannot pass through the loops of tabs 111 and 112, they are fixed to the underside of tabs 111 and 112. With this fixing, beads 121 and 122 are secured between the loops formed by tabs 111 and 112 and the knots 151 and 152 of the strings 131 and 141.
[0017] Since the cords 131 and 141 are of different lengths, the position of their ends is fixed as described above, allowing them to function as straps for purposes such as carrying by hand or over the shoulder.
[0018] Furthermore, by untying the knots 151 and 152 of the strings 131 and 141, the strings 131 and 141 can be freely passed through the loops formed by the beads 121 and 122 and the tabs 111 and 112, and the strings 131 and 141 can be completely detached from the bag body 101. In this way, by removing the beads and strings, this pouch can also be used as a so-called inner pouch.
[0019] Figure 2 is a schematic external view of the pouch with the beads and string removed. The bag body 201 and the tabs 211 and 212 that form the loop are depicted.
[0020] Preferably, the upper part of the pocket is configured to be opened and closed by a spring base. The spring base is composed of a pair (two pieces) of leaf springs and two hinges that connect the two leaf springs to each other at both ends. In the form of FIG. 2, the leaf springs are accommodated near the upper end of the bag body 201. A seam 202 by sewing can be seen at the upper part of the bag body 201 to accommodate the leaf springs. The two hinges are sewn to both side parts near the upper end of the bag body 201 and are not visible in this figure.
[0021] FIG. 3 is a schematic external view of the pocket in an open state. The description of the beads and the string is omitted. The leaf spring of the spring base is sewn to the vicinity 321 of the upper end of the bag body 301, and the two hinges 311, 312 can be slightly seen from the outside.
[0022] When the spring base is in the closed state, the two leaf springs extend straight and press against each other to close the upper part of the pocket. When opening this, the user places the thumb and index finger opposite to the two hinges 311, 312 and applies a pressing load from the outside to the inside with the fingertips. By this pressing operation, the two leaf springs move so as to warp outward around the hinges, and are forced to have an arcuate deformation with the hinges as the fulcrum, and transition from the stable position in the closed state to the open state. At this time, when the deformation of the leaf spring exceeds a certain angle (dead point), the restoring force of the leaf spring reverses from the "closing direction" to the "opening direction", and it opens suddenly. As a result, the bag body instantaneously transforms from a flat closed state to a state forming a rectangular or elliptical opening space.
[0023] In this operation, the hinges 311, 312 of the spring base are embedded or covered inside the bag body 301, and only the shaft part thereof is exposed at the outer edge of the opening. With this configuration, while ensuring the functionality as a rotation fulcrum during the opening operation, the design aesthetic appearance is enhanced, and a smooth opening operation with minimal snagging on the fingertips becomes possible.
[0024] When the user releases the pressure on the fingertip, the elastic restoring force of the spring base acts, and the hinge 311, 312 rotates and returns to the closed state again. As a result, the user can open and close the pocket with one hand.
Explanation of Signs
[0025] 101, 201, 301: Bag body 111, 112, 211, 212: Tab 121, 122: Bead 131, 141: String 311, 312: Hinge
Claims
1. The bag comprises a bag body with an opening at the top, at least two loop-shaped tabs fixed to both sides of the bag body, and two or more beads and two or more strings of different lengths detachably attached to the bag body. The bead is of a size that cannot pass through the loop of the tab and has a through hole. The two strings can pass through the through holes. When the bead is attached to the bag, the two strings pass through the through-hole of the bead from above, and a knot is formed between the strings below the bead. The knot is formed to a size that prevents it from passing through the through-hole of the bead, thereby fixing the ends of the strings to the bead by the knot. This fixing positions the bead between the loop formed by the tab and the knot of the string. A small shoulder bag.
2. The pouch according to claim 1, wherein the opening at the top of the pouch is configured to be openable and closable by a spring clasp, and the spring clasp consists of two leaf springs attached near the opening at the top of the pouch and two hinges connecting the two leaf springs at both ends thereof.
