Flexible wire storage case

Abstract

This invention provides a storage case that allows for smooth adjustment of the storage length by forming multiple overlapping oval rings between a single flexible wire and adjusting the length of the rings. [Solution] Between the flexible wires extending to the left and right, there are left and right bending rings 30a, 30b and an oval winding ring 50 with one and a half or more turns on the left and right sides of the extension 2 between them. The left bending ring 30a has a peripheral wall surrounding it, and on its left wall is a left outlet for the left end of the flexible wire, and on its right wall is a left opening 7au, 7ad for the extension, and a bending roller rotatably supported by a rotating guide means between its front and rear walls is a left bending ring case 4a. The right bending ring 30b has a peripheral wall surrounding it, and on its right wall is a right outlet for the right end of the flexible wire, and on its left wall is a right opening 7bu, 7bd for the extension, and a bending roller rotatably supported by a rotating guide means between its front and rear walls is a right bending ring case 4b. Multiple overlapping extensions 2 are stored in an orderly manner between the left and right bending ring cases 4a, 4b so that they can be extended and retracted.

Description

Technical Field

[0001] The present invention relates to a flexible wire storage case with adjustable length for storing flexible wire materials such as electric cords and vinyl tubes that can be bent flexibly.

Background Art

[0002] In daily life, when handling flexible wire materials such as electric cords and vinyl tubes that are less than 5 m in length and can be bent flexibly, they are usually stored by winding them into a loop of a certain size and then unwound and stretched when needed. In many cases, the wire materials are handled in a messy form both during storage and use. It is desired to store the flexible wire materials neatly and use them in an orderly manner. A winding structure is disclosed in Chinese Utility Model Publication No. 206857885, in which a relatively thin and flexible wire such as an earphone cable is alternately bent left and right on a single line, and a winding buckle with a winding shaft like a bobbin is provided at the bent ring portions at both ends of the bending, so that the flexible wire can be wound, stretched, and expanded. Also, an example of a cord case is disclosed in Japanese Patent Application Laid-Open No. 2017-199889, in which a flexible wire such as an electric cord is alternately bent left and right on a single line, and bending ring cases are provided at the bent ring portions at both ends of the bending. The wire is led out and stored in a thin and converged form from the extension openings inside both bending ring cases.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the aforementioned winding structure for earphone cables, etc., a drawback is that when storing them, the extended parts that come out from the wide openings inside both winding buckles tend to spread out in any direction, resulting in a messy and disorganized appearance. Furthermore, in the aforementioned cord cases for storing electrical cords, the openings for the extended portion of the folded cord are narrowed on the inside of both the left and right bend ring cases in order to consolidate the extended portion, resulting in the drawback that the cord cannot be moved smoothly and the length cannot be adjusted after storage. Furthermore, both proposals essentially involve placing the cord or cable on one surface and folding it alternately to the left and right in a single layer, then storing the folded portions in a case. While both proposals have the advantage of being thin in their storage form because they involve a single fold on one surface, when attempting to store the cord or cable by forming multiple folded portions, it becomes difficult to continuously fold the cord or cable alternately to the left and right at the folded portions, causing inconvenience for the average user when inserting the folded portions into the case. Also, when attempting to continuously fold the cord or cable alternately to the left and right, a section of the cord or cable will be created between the folded portions. This interferes with the movement of the cord or cable when adjusting the storage length, hindering smooth operation. Moreover, the crossing of the cord or cable at the extension section increases the height of that section, resulting in a form defect where the crossing section does not match the other non-crossing sections of the extension section. In view of the aforementioned drawbacks, the present invention provides an easy-to-use flexible wire storage case that can store flexible wires such as power cords in multiple layers on a single line, and that also allows for smooth adjustment of the storage length on a single line.

[0010] As described above, the present invention is configured to produce the following effects. Since the flexible wire can be wound in a loop in one direction to form a winding loop, the user can easily form multiple winding loops and store them in the left and right winding loop cases. Furthermore, the user can easily wind the flexible wire directly into the winding loop cases placed on the left and right in a loop in one direction. In addition, the flexible wire can be wound in both clockwise and counterclockwise directions in the same way around the winding loop case. The storage shape is neat and orderly, as it is an oval parallel loop with multiple half-turns of one and a half or more, and the multiple extended parts are aligned in parallel. Furthermore, since the openings of the extension sections of the left and right bendable ring cases can be opened and closed vertically into upper and lower half openings, the storage length of the flexible wire can be adjusted by opening the upper and lower half openings, and the storage of the flexible wire can be maintained by closing the upper and lower half openings. This results in a flexible wire storage case that can store the extension sections in a single, thin bundle that extends along each other, and allows for smooth adjustment of the storage length. For relatively strong flexible wires such as power cords, when the extension length is short, the upper and lower openings of the extension section can be kept open to maintain storage, allowing the flexible wires to be neatly stored at the desired length without having to open and close the case.

[0012] The embodiments of the present invention will be described below based on examples. Figure 1 shows an oval-shaped coiled ring 50 formed by winding the left end 1a of the flexible wire 1 clockwise two and a half times towards the rear (front) with the left end 1a facing forward, and extending the right end 1b at the rear to the right. The coiled ring 50 forms a left bent ring portion 3a, a right bent ring portion 3b, and a parallel extended portion 2 between them. Three extended portions are formed on the upper side and two on the lower side in parallel. In the embodiments shown below, the coiled ring 50 shown here is housed in the left and right bent ring cases in this form. Alternatively, the coiled ring 50 can be wound into the left and right bent ring cases in this shape.

[0013] Figures 2 to 10 show an embodiment of the flexible wire storage case 10. The flexible wire storage case 10 surrounds its left bent ring portion 3a with the peripheral wall of the left bent ring case 4a, and its right bent ring portion 3b with the peripheral wall of the right bent ring case 4b, forming a thin extension portion 2 that extends along each other between them. The left end portion 1a of the flexible wire 1 is led out to the left from the left outlet 6af on the left wall of the left bent ring case 4a, and the right end portion 1b of the flexible wire 1 is led out to the right from the right outlet 6bb on the right wall of the right bent ring case 4b. The left-bending ring case 4a is divided into two parts: the upper left case 41au, which forms the front wall portion 4af on the approximately front side (far side) from its approximately upper wall portion 4au, and the lower left case 41ad, which forms the rear wall portion 4ab on the approximately rear side (near side) from its approximately lower wall portion 4ad. The upper left case 41au has a left outlet 6af for the flexible wire on its left wall portion, and an upper left half opening 7au on its right wall portion, which is the upper half of the left opening. The lower left case 41ad has a left outlet 6ab for the flexible wire on its left wall portion, and a lower left half opening 7ad on its right wall portion, which is the lower half of the left opening. Inside the left-bending ring case 4a, there are three left-bending rollers 5a, 5a1, and 5a2 of the same shape, which are divided into three sections front to back, corresponding to the three overlapping left-bending ring portions 3a in the front to back. Each of the left-bending rollers 5a, 5a1, and 5a2 has an axle hole of the same size in the center. Inside the front wall portion 4af of the upper left case 41au and the rear wall portion 4ab of the lower left case 41ad, there are upper left roller shafts 4as and 4at, respectively, which protrude forward and backward to a position midway between the cases, at a position approximately at the center of the left bent ring portion 3a, and they function as means for guiding the rotation of the left bent rollers 5a, 5a1, and 5a2. The upper left case 41au and the lower left case 41ad are fitted together facing each other and assembled to form a single left bent ring case 4a, passing through the shaft holes of the three left bent rollers 5a1, 5a2, and 5a. The upper left case 41au and the lower left case 41ad are fitted together in such a way that they can rotate relative to each other within a certain range defined around the left bent rollers 5a1, 5a2, and 5a via the roller shafts 4as and 4at on their respective sides, and the upper left half opening 7au on the upper half of the left opening, It performs the function of opening and closing the lower left half of the left opening, 7ad.

[0014] Therefore, as shown by arrows 30a and 30b in Figure 9, the upper left case 41au and lower left case 41ad of the left-bent ring case 4a can open and close their respective left upper half opening 7au and lower left half opening 7ad. In the figure, the upper left case 41au is provided with a lower half retaining claw 8au that extends downward along the left side wall of its peripheral wall. On the other hand, the lower left case 41ad is also provided with an upper half retaining claw 8ad that extends upward along the left side wall of its peripheral wall. When the left upper half opening 7au and lower half opening 7ad of the left opening are closed, these two lower half retaining claws 8au and upper half retaining claws 8ad fit into grooves at the rear ends of the left side walls of the other side, preventing the left upper half opening 7au and the left lower half opening 7ad from moving in the opening direction, and thus function as an opening and closing means to maintain a closed state. Thus, the opening closing means includes a closing mechanism consisting of retaining claws 8au and 8ad that maintain the closed state of the upper left half opening 7au and the lower left half opening 7ad of the left opening.

[0015] The right-bending ring case 4b is symmetrical to the left-bending ring case 4a with respect to the longitudinal center of the winding ring 50. Its shape, structure, and partial functions are also exactly the same, and it moves symmetrically, so in the diagram, identical parts are simply indicated with the same numbers followed by the subscript "b," and a detailed explanation is omitted. As shown in Figure 8, the lower cases 41ad and 41bd of the left and right bendable ring cases 4a and 4b can be removed to open the rear (front) side of the cases, allowing a coiled ring 50 of the flexible wire 1, consisting of the left bendable ring portion 3a, the extension portion 2, and the right bendable ring portion 3b, to be inserted into the left and right bendable ring cases 4a and 4b. Figure 8 shows the coiled ring 50 inserted and the extension portion 2 fastened with hook-and-loop fasteners 9. Figure 2 shows the coiled loop 50 stored inside the flexible wire storage case 10. The extended portion 2 is brought together along the narrowed left openings 7au and 7ad and 7bu and 7bd on the left and right sides, and stored in a single bundle shape. If there is a long gap between the left and right cases, the extended portion 2 can be secured by wrapping it with hook-and-loop fasteners 9 or the like, as shown in the figure, if desired.

[0016] When adjusting the storage length of the flexible wire 1, remove the retaining tabs 8au and 8ad and 8bu and 8bd of the left and right bending ring cases with your fingers, and rotate the upper and lower halves of the left and right bending ring cases around the front and rear roller axes on each side, as shown by arrows 30a and 30b in Figure 9, to open the left upper half opening 7au and the right upper half opening 7bu upwards, and the left lower half opening 7ad and the right lower half opening 7bd downwards. In Figure 9, the upper left half opening 7au and lower left half opening 7ad, and the upper right half opening 7bu and lower right half opening 7bd of the left and right bend ring cases 4a and 4b are all fully open. The left end 1a of the flexible wire 1 is detached from the left outlet 6af and moved to the upper space near the front wall of the left wall of the bend ring case 4a, and the upper part of the bend ring 3a is pulled straight to the left as indicated by arrow p1a. Similarly, the right end 1b of the flexible wire 1 is pulled straight to the right as indicated by arrow p1b, extending the length of both ends of the flexible wire 1. The winding ring 50 is securely wrapped around the bending rollers 5a, 5a1, 5a2 (not shown) and 5b, 5b1, 5b2 (not shown) of the left and right bending ring cases, and is open parallel to each other vertically. The stretched portion 2 is stretched parallel to each other inside the upper and lower half openings on the left and right sides, and the left bending ring case 4a is moving to the right as indicated by the arrow pca, and the right bending ring case 4b is moving to the left as indicated by the arrow pcb, shortening the length of the winding ring 50. In this way, the ends 1a and 1b of the left and right flexible wires 1 can be attached and detached as desired. Conversely, if the left and right bending ring cases 4a and 4b are pulled apart to the left and right in the opposite direction to the arrows pca and pb, the left end 1a and the right end 1b of the flexible wire 1 are pulled towards the bending ring cases to the right and left in the opposite direction to the arrows p1a and p1b, causing the length of the winding ring 50 to stretch slightly (about 1 / 5 of the length of the flexible wire 1 that is pulled in). With the upper and lower half openings of the left and right bending ring cases open, the winding ring 50 is firmly held by the left and right bending rollers when adjusting the length of the flexible wire 1, and there are no parts that obstruct the movement of the winding ring 50, allowing for smooth adjustment of the storage length in both forward and reverse directions. When storing relatively flexible wires, such as power cords, in short, spaced extension sections, the left end 1a and right end 1b of the flexible wire 1 can be fitted into the left outlet 6af and right outlet 6bb, respectively, while the upper and lower halves of the left and right bend ring cases are left open as shown in Figure 9, and the storage can be maintained in this state. The operation of opening and closing the upper and lower halves of the extension section openings and the selection of the storage configuration of the extension section are at the user's discretion.

[0017] Figures 11 to 17 show flexible wire storage cases 10' of other embodiments. The left and right bendable ring cases 4'a and 4'b of the embodiments shown here are almost identical to the bendable ring cases of the flexible wire storage case 10 of the previously described embodiment, except for the opening and closing means that stop the movement of the upper and lower openings of the extension parts on the left and right sides in the opening direction. Therefore, identical parts are indicated by the same numbers with the subscript "'", and their detailed explanation is omitted. New reference numerals are used to indicate newly different parts, and their details are explained. The flexible wire storage case 10' does not have the opening and closing means of the lower half retaining claws 8au and upper half retaining claws 8ad on the left wall of the left bent ring case 4'a and the lower half retaining claws 8bu and upper half retaining claws 8bd on the right wall of the right bent ring case 4'b of the flexible wire storage case 10 of the above embodiment. In this embodiment, as is clear from Figures 11, 12 and 16, a narrow-width hooking groove 11au is provided at the right end of the upper wall of the left upper half case 41'au, and a hooking groove 11ad is also provided at the right end of the lower wall of the left lower half case 41'ad. A left rear hooking claw 12ab is provided that extends from the rear wall side of the left lower half case 41'ad along the wall surface of the left upper half case 41'au to above the hooking groove 11au, and has a claw at its upper end that protrudes toward the front hooking groove 11au side. On the other hand, a left front hooking claw 12af is provided, which extends from the front wall side of the left upper half case 41'au along the wall surface of the left lower half case 41'ad downwards to the hooking groove 11ad, and has a claw at its lower end that protrudes toward the rear hooking groove 11ad. When the left upper half opening 7'au and the left lower half opening 7'ad of the left opening are closed, these two hooking claws 12ab and 12af engage with each other in the opposing hooking grooves 11au and 11ad, respectively, and act as an opening and closing means to stop the movement of the left upper half opening 7'au and the left lower half opening 7'ad in the opening direction and maintain the closed state.

[0018] The right-bent ring case 4'b is symmetrical to the left-bent ring case 4'a with respect to the center of the center of the wound ring 50'. Since its shape, structure, and partial function are also the same, identical parts are indicated in the diagram simply by adding the subscript "b" to the same number, and detailed explanations are omitted. Figures 11 to 16 show the coiled loop 50' stored inside the flexible wire storage case 10'. The extended portion 2' is gathered and stored along the narrowed upper half openings 7'au and 7'ad, and upper half openings 7'bu and 7'bd on the left and right sides. If there is a long gap between the left and right cases, the extended portion 2' can be secured by wrapping it with hook-and-loop fasteners 9' or the like, as desired.

[0019] When adjusting the storage length of the flexible wire 1', the two front and rear hooks 12af and 12ab, and hooks 12bf and 12bb of the left and right bending ring cases 4'a and 4'b are released with fingers as indicated by the arrows in Figure 16, and the upper left case 41'au and upper right case 41'bu are rotated around the upper left roller shaft 4'as and upper right roller shaft 4'bs (not shown), and the lower left case 41'ad and lower right case 41'bd are rotated around the lower left roller shaft 4'at and lower left roller shaft 4'bt (not shown), respectively, as shown in Figure 17, thereby opening the upper left half opening 7'au and upper right half opening 7'bu upwards, and the lower left half opening 7'ad and lower right half opening 7'bd downwards. In Figure 17, the upper left half opening 7'au and lower left half opening 7'ad, and the upper right half opening 7'bu and lower right half opening 7'bd of the left and right bending ring cases 4'a and 4'b are all fully open. The left end 1'a of the flexible wire 1' is pulled to the left, indicated by arrow p1'a, and the right end 1'b of the flexible wire 1' is pulled to the right, indicated by arrow p1'b, extending the length of both ends of the flexible wire 1'. The winding ring 50' is firmly wound around the left and right bending rollers 5'a, 5'a1, 5'a2 and 5'b, 5'b1, 5'b2 (not shown), and is opened vertically, with the stretched section 2 taut inside the left and right upper and lower half openings. The left bending ring case 4'a moves to the right, indicated by arrow pc'a, and the right bending ring case 4'b moves to the left, indicated by arrow pc'b, shortening the length of the winding ring 50'. The reverse operation is the same as in the example above. The openings on the upper and lower halves of the extension sections of the left and right bending ring cases are open, so that when adjusting the length of the flexible wire 1', the winding ring 50' is firmly held by the left and right bending rollers, and there are no parts that obstruct the movement of the winding ring 50', allowing for smooth adjustment of the storage length.

[0020] Figures 18 to 22 show flexible wire storage cases 10" of other embodiments. The left and right bend ring cases 4"a and 4"b of the embodiments shown here are basically the same as the bend ring case parts of the flexible wire storage case 10' of the previously described embodiment, except for the opening and closing means that stop the movement of the upper and lower half openings of the left and right openings in the opening direction. Therefore, the same parts are indicated by the same numbers with the subscript "", and their detailed explanation is omitted. New parts that are different are given new reference numerals and their details are explained. In this embodiment, the front wall portion 4"af and the rear wall portion 4"ab of the upper left case 41"au and lower left case 41"ad of the left bend ring case 4"a are assembled in such a way that the mating parts with each other on the front wall portion 4"af and rear wall portion 4"ab sides do not rotate relative to each other around the roller axis. The same applies to the right bend ring case 4"b.

[0021] The left opening opening and closing mechanism of the left bent ring case 4"a in this embodiment will be explained with reference to Figures 18, 19, and 21. The left upper pivot shaft 22au is fixed to a front-to-back boss located in the middle of the upper wall portion 4"au of the left upper half case 41"au of the left bent ring case 4"a. The boss portion at the left end of the left upper half opening 7"au of the left opening is rotatably supported by the left upper pivot shaft 22au, and the right end of the left upper half opening 7"au can be opened and closed vertically. On the other hand, the left lower pivot shaft 22ad is also fixed to a front-to-back boss located in the middle of the lower wall portion 4"ad of the left lower half case 41"ad, and the boss portion at the left end of the left lower half opening 7"ad of the left opening is rotatably supported by the left lower pivot shaft 22ad, and the right end of the left lower half opening 7"ad can also be opened and closed vertically. The front wall portion 4"af and the rear wall portion 4"ab of the upper left half opening 7"au are supported at their upper ends by pivot pins 24af and 24ab, respectively, and are rotatably supported around these pivot pins, with latches 22af and 22ab extending downward to the wall of the lower left half opening 7"ad. The lower ends of these latches 22af and 22ab are shaped like hooks that open in a U-shape on the left side. Therefore, when the upper left half opening 7"au and the lower left half opening 7"ad are closed, the latches 22af and 22ab can be operated with a finger to hook onto the front and rear latch pins 25af and 25ab on the lower left half opening 7"ad, respectively, thereby maintaining the closed state of the upper and lower openings. Figure 18 shows this state. The right opening opening and closing mechanism of the right bending ring case 4"b can similarly perform the vertical opening and closing movement and maintain the closed state of the upper right half opening 7"bu and the lower right half opening 7"bd.

[0022] In Figure 22, the upper left half opening 7"au and lower left half opening 7"ad, and the upper right half opening 7"bu and lower right half opening 7"bd of the left and right bent ring cases 4"a" and 4"b are all fully open. The left end 1"a of the flexible wire 1" is pulled to the left, as indicated by arrow p1"a, and the right end 1"b of the flexible wire 1" is pulled to the right, as indicated by arrow p1"b, thereby extending the length of both ends of the flexible wire 1". The winding ring 50" is firmly wound around the left and right bending rollers 5"a, 5"a1, 5"a2 and 5"b, 5"b1, 5"b2 (not shown), and is opened vertically, with the stretched section 2 taut inside the upper and lower openings on the left and right. The left bending ring case 4"a moves to the right, as indicated by arrow pc"a, and the right bending ring case 4"b moves to the left, as indicated by arrow pc"b, thus shortening the length of the winding ring 50". The operation in the reverse direction is the same as in the example described above. The openings on the upper and lower halves of the extension sections of the left and right bending ring cases are open, so that when adjusting the length of the flexible wire 1", the winding ring 50" is firmly held by the left and right bending rollers, and there are no parts that obstruct the movement of the winding ring 50", allowing for smooth adjustment of the storage length.
