Description

Technical Field

[0001] The present invention relates to a rope guide for guiding a rope body for length adjustment when installed on a soft, easily deformable material such as fabric, and a length adjustment member provided with the rope guide. Prior Technology

[0002] Previously, length-adjustable ropes were installed on soft items such as tents, and the length of the item was adjusted by pulling one end of the rope to move the other end. For example, the rope end fixing position changing part disclosed in Patent Document 1 changes the position of the item to a second position via a rope through the operation of an operating part provided in a first position. The operating part includes: two strips having a row of teeth containing multiple teeth that engage or disengage with each other; a first pull head and a second pull head, each row of teeth being inserted through, and engaging or disengaging the teeth by sliding operation; and a connecting member connecting the first pull head and the second pull head. Any one of the first pull head, the second pull head, and the connecting member has a rope end mounting part for mounting the rope. One end of the rope is mounted to the rope end mounting part, and the other end is mounted to the second position of the item. The first pull head has a locking claw member that elastically enters the gap between the teeth when sliding stops to stop the sliding of the pull head, and disengages in conjunction with the sliding operation of the connecting member to enable the sliding of the pull head.

[0003] Patent Document 1: WO2006 / 137293 Summary of the Invention

[0004] [Problem to be Solved by the Invention] In the prior art, when the first and second zipper heads are slid, the item stretches and contracts along the entire cord, making it impossible to adjust the item only to the desired position. Therefore, it is considered to insert the length-adjusting cord into a rigid tube, thereby preventing the portion containing the tube from stretching and allowing the portion outside the tube to stretch and contract. However, the portion containing the tube lacks the flexibility of an item, making it difficult to move around in clothing, resulting in a poor wearing and usability experience. Furthermore, the drainage of the inner space of the tube is poor, and drying takes time when it becomes wet from washing.

[0005] The present invention was made in view of the problems of the prior art, and its object is to provide a length adjustment member that uses a deformable rope guide and can extend and retract to a desired position of a soft article by means of remote operation. [Methods for solving problems]

[0006] The present invention is a rope guide, which is disposed in a portion between a first position and a second position of a soft article, and includes a plurality of chain teeth mounted on the article on a line connecting the first position and the second position. Through holes are provided in the chain teeth, and the through holes of the plurality of chain teeth are independently connected to each other on an imaginary line, and guides the rope for length adjustment connecting the first position and the second position in a sliding manner.

[0007] Multiple chain teeth are mounted side-by-side on the side edge of the belt portion along its length, the belt portion being disposed on the article. A core wire with higher rigidity than the belt portion is integrally provided on the side edge of the belt portion, and the chain teeth are fixed to the core wire.

[0008] The chain teeth are arranged adjacent to each other in a separated manner. Each chain tooth has a protrusion that projects toward the adjacent chain tooth and a recess that engages with the protrusion of the adjacent chain tooth. Each chain tooth is formed of a continuous coil, and the inner space of the coil is the through-hole.

[0009] A length adjusting member allows for the repositioning of an adjusting member located at a second position on a soft article by operating an operating part disposed at a first position on the article via a length adjusting rope. One end of the rope is attached to the operating part, and the other end is attached to the adjusting part. A rope guide is provided between the first and second positions. The rope guide includes multiple teeth attached to the article and connected to a line between the first and second positions. Through holes are provided in the teeth, and the through holes of the multiple teeth are independently connected to each other on an imaginary line, guiding the rope in a slidable manner. Operating the operating part causes the rope to slide relative to the article and the rope guide. While maintaining the shape or length of the rope guide, a portion of the article near the adjusting part outside the rope guide is extended or retracted by remote operation, thereby changing the position of the adjusting part.

[0010] An elastic body is provided that extends and retracts in the direction connecting the first position and the second position. The elastic body is elastically deformed when the interval between the first position and the second position changes, and is restored by applying force so that the interval between the first position and the second position is restored. [The effects of the invention]

[0011] The rope guide and length adjustment component of this invention are flexible and easy to use, and can be remotely operated to extend or retract soft items to the desired position. The rope for length adjustment is also easy to operate, and the rope guide does not bend unintentionally, maintaining the shape or length of the path. Items can be easily extended or retracted outside the rope guide. Simple Explanation of the Diagram

[0013] Hereinafter, embodiments of the present invention will be described based on the drawings. FIG1 is a schematic diagram of the length adjusting member 10 of the first embodiment of the present invention. The length adjusting member 10 changes the position of the adjusting member 18 disposed at the second position B of the article 12 via the length adjusting rope 16 by operating the operating part 14 disposed at the first position A of the soft article 12. The rope 16 can be, for example, a rope made of natural fiber or resin or a metal wire, as long as it is thin and soft and can slide smoothly relative to the article 12 or the rope guide 20 described later without friction, and the material can be freely changed. One end of the rope 16 is installed in the operating part 14, and the other end of the rope 16 is installed in the adjusting part 18.

[0014] A rope guide 20 is disposed in a portion between mutually separated first position A and second position B. The rope guide 20 includes a plurality of teeth 22 configured along a line connecting the first position A and the second position B and mounted on the article 12. Through holes 24 are provided through the teeth 22, and as described later, the through holes 24 of the plurality of teeth 22 are independently connected to each other on an imaginary line, guiding the rope 16 in a slidable manner.

[0015] Between the first position A and the second position B, an elastic body 26 is provided that extends and retracts in the direction connecting the first position A and the second position B. The elastic body 26 is elastically deformed when the interval between the first position A and the second position B changes, and returns to its original state by applying force, thus restoring the interval between the first position A and the second position B. The elastic body 26 is, for example, a coil spring, fixed to the article 12 or rope guide 20, etc., in such a way that the insertion direction of its internal space, i.e., the extension and retraction direction, is consistent with the direction connecting the first position A and the second position B, and a rope 16 is slidably inserted through its inner space. The elastic body 26 is connected to the rope 16; if the rope 16 is operated to slide when the interval between the first position A and the second position B changes, the elastic body 26 extends and retracts accordingly.

[0016] A rope end fixing position changing member is provided in the operating part 14, which moves one end of the rope 16 and locks it at any position between the operating part 14 and the operating part 14a. The rope end fixing position changing member is, for example, the rope end fixing position changing member 38 of the article disclosed in Patent Document 1.

[0017] Next, the rope guide 20 will be described in detail based on Figures 2-4. The rope guide 20 has multiple teeth 22, which are mounted side-by-side on the longitudinal side edge 28a of a strip portion 28 made of a long strip of fabric, etc. The strip portion 28 is attached to the article 12 to form the rope guide 20. A core wire 30 with higher rigidity than the strip portion 28 is integrally provided on the side edge 28a of the strip portion 28, and teeth 22 are fixed to the core wire 30. The teeth 22 are slightly separated from each other, and a predetermined gap is provided between adjacent teeth 22. This allows the rope guide 20 to easily bend in a direction intersecting the arrangement direction of the teeth 22, thereby easily following the deformation of the article on which it is attached.

[0018] The chain tooth 22 is made of synthetic resin, for example, and is a hexahedron shape that is elongated in one direction, with each corner chamfered or rounded. The chain tooth 22 is a thin shape with a relatively small width in the thickness direction of the belt portion 28, and the pair of larger side surfaces of the chain tooth 22 are positioned parallel to the side surfaces of the belt portion 28. The long side of the side surface of the chain tooth 22 is positioned at a right angle to the side edge portion 28a of the belt portion 28, with about half of the long side formed and fixed to the side edge portion 28a of the belt portion 28, and the remaining half protruding from the side edge portion 28a of the belt portion 28. A through hole 24 is provided through the protruding portion of the chain tooth 22 from the side edge portion 28a of the belt portion 28, and the through hole 24 is provided parallel to the side edge portion 28a and passes through the chain tooth 22. Multiple chain teeth 22 of the same shape are arranged along the side edge portion 28a, and the through holes 24 of the multiple chain teeth 22 are independently connected to each other on an imaginary line along the side edge portion 28a.

[0019] The resin content of the teeth 22 is approximately 30% to 90% relative to the spacing between them on the belt portion 28. The size of the teeth 22 is, for example, 3.56 mm along the side edge 28a, with a spacing of 0.6 mm between them. In this case, the resin content / spacing is approximately 86%. Due to the small gaps between the teeth 22 and the chamfered or rounded corners, the teeth 22 disposed on the article 12 via the belt portion 28 can, to some extent, follow the curvature of the belt portion 28, thus easily adapting to the deformation of the soft article 12. Furthermore, they do not shrink or buckle along the length of the belt portion 28.

[0020] Next, the operation of the length adjustment member 10 will be explained. The operating unit 14 is operated to reach the operating unit 14a located to the right in FIG. 1, causing the rope 16 to slide relative to the article 12 and the rope guide 20. Since the rope guide 20 has moderate rigidity and is not easily bent, while the shape and spacing of the path of the rope guide 20 remain approximately constant, a portion of the article 12 outside the rope guide 20 is curled up by remote operation, thereby changing the position of the adjustment unit 18. The position of the adjustment unit 18, located at the second position B, moves to the right to the adjustment unit 18a, and the length L1 of the portion located on the left side in FIG. 1 compared to the rope guide 20 becomes the length L2, thus becoming shorter. In this way, the position of the adjustment unit 18, which is away from the operating unit 14, can be remotely operated by operating the operating unit 14.

[0021] For example, as shown in Figures 5(a), 5(b), and 6, item 12 is a pyramidal tent 12a. Figures 5(a) and 5(b) show the exterior of tent 12a, and Figure 6 shows the interior of tent 12a. Tent 12a has a window 32 at its upper part, and the outer surface of the window 32 is covered by a cover member 34 that can be opened and closed. The lower end of the cover member 34, which is a roughly horizontal straight line, is an opening edge. An opening device 36 is installed on the opening edge. This opening device 36 is straight when closed and bends into a V-shape when open. The right end of the opening device 36 is fixed to tent 12a. The left end of the opening device 36 is a second position B, and is provided with an adjustment part 18 that can change position via a rope 16. The adjustment part 18 is, for example, a movable part that is positioned along the opening edge of the window 32 and can move.

[0022] The first position A is located below the interior side of the tent 12a and is equipped with an operation section 14. The separate adjustment section 18 and the operation section 14 are connected by a rope 16. The rope 16 extends to the right from the adjustment section 18 in a generally horizontal direction in Figures 5(a) and 5(b), passes near the right end of the opening device 36, and then changes direction to extend downward in a straight line to reach the operation section 14.

[0023] Near the right end of the opening device 36 and between it and the operating section 14, a rope guide 20 is provided, with its strap 28 sewn onto the tent 12a. The rope 16 can be slidably inserted into the insertion hole 24 of the chain tooth 22 of the rope guide 20. The operating section 14 may also use the rope end fixing part changer 38 disclosed in Patent Document 1.

[0024] Next, the method of using the length adjustment member 10 installed on the tent 12a will be described based on Figures 5(a) and 5(b). Figure 5(a) shows the state where the window 32 is closed using the cover member 34. To open the cover member 34 from the window 32, the operating part 14 is moved to the position of the operating part 14a, so that the rope 16 slides relative to the tent 12a and the insertion hole 24 of the chain tooth 22 of the rope guide 20. As a result, the adjustment part 18 is pulled by the rope 16 and moved to the adjustment part 18a. While the shape and length of the part of the tent 12a along the path where the rope guide 20 is provided remain approximately constant, the part near the adjustment part 18a other than the rope guide 20, where the length L1 of the opening device 36 is located, becomes the length L2 and shortens. The opening device 36 is bent in a V-shape, forming an opening between it and the opening edge of the window 32. As shown in Figure 5(b), the cover member 34 is opened from the window 32, allowing ventilation. The operation unit 14 is operated to remotely operate the adjustment unit 18, which is located away from the operation unit 14, thereby opening and closing the window 32. When the cover member 34 is to be closed, the operation unit 14a is returned to the operation unit 14, thereby returning the length L2 of the opening device 36 to the length L1, making the opening device 36 straight, and the window 32 is covered by the cover member 34.

[0025] The length adjustment member 10, via the rope end fixing part changer 38 provided on the operating part 14, allows the operating part 14 and the rope 16 to move easily together, and can be locked at any position between the operating part 14 and the operating part 14a. In this way, the opening of the cover member 34 can be maintained at any size.

[0026] The tent 12a shown in Figures 5(a), 5(b), and 6 can also have an elastic body 26 (not shown) installed at any position between the first position A and the second position B. When the force that holds the end of the rope 16 to the operating part 14a is released from the state where the cover member 34 is open, the force applied by the elastic body 26 causes the end of the rope 16 to return to the position of the operating part 14, thereby automatically restoring the state where the cover member 34 covers the window 32.

[0027] With the rope guide 20 and length adjustment member 10 in this embodiment, for a flexible tent 12a, the rope 16 can be operated remotely via the operating part 14 located at the bottom of the tent 12a. The length of the opening device 36 on the cover member 34 located at the top of the tent 12a is adjusted for opening and closing. By extending and retracting only the opening device 36, the shape and length of the rope guide 20 are maintained, while the main body of the tent 12a does not extend or retract, thus maintaining the shape of the tent 12a. The chain teeth 22 of the rope guide 20 are independent, thus having gaps and good drainage, preventing water from washing or rain from accumulating in the insertion holes 24. The rope guide 20 is flexible and can deform along the flexible tent 12a. The rope guide 20 fixes the chain teeth 22 to the strap 28, so the strap 28 can be installed on the tent 12a by simple operations such as sewing or gluing.

[0028] Furthermore, by providing the rope end fixing part 38 of the item to the operating part 14, the operating part 14 can be easily moved and can be locked at the position of the operating part 14a to maintain the opening of the cover member 34. The opening of the cover member 34 can be maintained at any size by locking at any position between the operating part 14 and the operating part 14a.

[0029] In addition, by providing the elastic body 26, when the force that holds the end of the rope 16 to the operating part 14a is released, the force applied by the elastic body 26 can restore it to the position of the operating part 14, thereby automatically restoring it to the state where the cover member 34 covers the window part 32.

[0030] Next, the rope guide 40 of the second embodiment of the present invention will be described based on Figures 7 and 8(a) to 8(c). Furthermore, components identical to those in the previous embodiment will be labeled with the same reference numerals and their descriptions will be omitted. In this embodiment of the rope guide 40, a plurality of chain teeth 42 are mounted side-by-side on the side edge 28a of the belt portion 28 along its length direction. The belt portion 28 is provided on the article 12 to become the rope guide 40. The chain teeth 42 are separated from each other, and a predetermined gap is provided between adjacent chain teeth 42. The chain teeth 42 are made of synthetic resin and are hexahedral in one direction. The long side of the chain tooth 42 is positioned at a right angle relative to the side edge 28a of the belt portion 28. Approximately half of the long side is formed and fixed to the side edge 28a of the belt portion 28, and the remaining half protrudes from the side edge 28a of the belt portion 28.

[0031] Figure 8(a) shows a front view of the rope guide 40. At the end of the side edge 28a of the belt portion 28 where the chain tooth 42 is formed and fixed, a protrusion 44 is provided, protruding towards the adjacent chain tooth 42a below the figure. The protrusion 44 is disposed in contact with the surface of the belt portion 28 and protrudes in a triangular shape towards the adjacent chain tooth 42a below the figure, extending beyond the gap and reaching the interior of the chain tooth 42a. A recess 46 is formed on the side of the chain tooth 42 opposite to the protrusion 44. The recess 46 opens upward and engages with the protrusion 44 of the adjacent chain tooth 42b above the figure. The recess 46 is formed by cutting open the portion in contact with the surface of the belt portion 28.

[0032] Figure 8(c) shows a rear view of the rope guide 40. On the rear side, a protrusion 44 is provided adjacent to the chain tooth 42b above the diagram of the chain tooth 42, and a recess 46 is formed that opens downward and engages with the protrusion 44 of the chain tooth 42a adjacent to the chain tooth 42a below the diagram. By interlocking the protrusion 44 and the recess 46, the row of chain teeth 42 has flexibility and the rigidity of the belt portion 28 in the length direction is increased. The protrusion 44 and the recess 46 are located on the front and back sides of the belt portion 28 and are provided in pairs. Each protrusion 44 faces each other on the front and back sides of the belt portion 28, thus increasing the rigidity of the belt portion 28. A through hole 24 is provided through the portion of the chain tooth 42 that protrudes from the side edge 28a of the belt portion 28, which does not hinder the engagement of the protrusion 44 and the recess 46, allowing the rope 16 to be slidably guided.

[0033] The rope guide 40 in this embodiment is used in the same way as in the previous embodiment and has the same effect. The protrusions 44 and concave portions 46 of the chain teeth 42 engage with each other, thereby providing flexibility and increasing rigidity.

[0034] Next, the rope guide 50 of the third embodiment of the present invention will be described based on Figures 9(a) to 9(c). Furthermore, components identical to those in the previous embodiment will be labeled with the same reference numerals and their descriptions will be omitted. In the rope guide 50 of this embodiment, a plurality of chain teeth 52 are formed by continuous coils 54, which are made of synthetic resin and are fused to the side edge 28a along the length direction on the front side of the belt portion 28. The inner space of the coil 54 is a through hole 56. The belt portion 28 is provided on the article 12 to become the rope guide 50. The chain teeth 52 formed by the coils 54 are continuous, but the ratio of one chain tooth 52 to a spacing of a row of coils of chain teeth 52 arranged on the belt portion 28 is, for example, resin portion / spacing = approximately 40%.

[0035] The rope guide 50 in this embodiment is used in the same way as in the previous embodiment and has the same effect. In particular, since the chain teeth 52 are formed by coils 54, long rope guides 50 can be manufactured continuously in a short time.

[0036] Furthermore, the rope guide and length adjuster of the present invention are not limited to the embodiments described above. The opening device of the tent with the length adjuster installed can also have a structure other than those described above. In addition, the items with the length adjuster installed can be used not only for tents, but also for various items such as clothing, hats, gloves, and bags, and the length of various parts can be adjusted. Regarding the shape of the chain teeth or the strap of the rope guide, as long as the rope can be guided in a sliding manner, the shape or material can be appropriately selected. The strap can be made of cloth or film. The rope end fixing part installed on the operating part can be changed. The shape of the operating part, the adjusting part, and the elastic body is not limited, and if the elastic body is not needed, it may not be present. The material, thickness, and shape of the rope are not limited, and it can be elastic in cases where clothing or other items require easy movement, and a rubber rope or the like can be provided between the rope and the adjusting part.
