Description

[Technical Field]

[0001] This invention relates to a tool for correcting the shape of rattan, and more particularly to a tool for correcting rattan used in wickerwork such as baskets from its original shape to a shape suitable for wickerwork. [Background technology]

[0002] By taking advantage of its excellent strength, workability, texture, etc., rattan can be woven into a desired shape and is widely used as a material for various crafts, not only for furniture such as chairs and tables, but also for furnishings such as baskets and bags, and decorative items such as wreaths (see, for example, Patent Document 1).In addition, these crafts made from rattan are also popular as a hobby, such as rattan weaving (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-21403 [Patent Document 2] Utility Model Registration No. 3250197 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, rattan used as a material for rattan weaving is generally sold commercially in a state where one or more strands are wound into a ring, and purchased rattan retains the twist of the wound ring, making it difficult to use as is. Therefore, when actually using rattan as a material for rattan weaving, it is necessary to soften the purchased rattan by, for example, soaking it in water and then straightening it into a shape suitable for use (for example, a straightened shape). However, straightening rattan in the shape it is in as purchased requires a certain degree of experience and skill, making it extremely difficult and time-consuming, especially for beginners.

[0005] For example, if there were a tool that could hold rattan in a straightened state, it would be possible to remove the twisting of the rattan and make it easier to use for rattan weaving. In that case, it would be desirable for the tool to be small enough to be mailed or carried along with the rattan that is the material for the weaving. However, the rattan used for weaving is generally several tens to several hundred centimeters long, so a tool designed to accommodate this length would be difficult to fit into a bag or box.

[0006] In view of the above circumstances, the technical problem to be solved in this specification is to provide a tool that allows even a beginner to easily correct rattan from the shape it is in when purchased into a shape suitable for rattan weaving, and that can be made compact. [Means for solving the problem]

[0007] The above-mentioned problem is solved by the rattan straightening tool of the present invention. That is, this tool is for straightening bundles of rattan used in rattan weaving into a stretched shape, and is characterized by comprising a tubular body with a hole passing through it in the longitudinal direction, the tubular body having a longitudinal dimension, an inner diameter dimension of the hole, and bending rigidity sufficient to maintain the stretched shape of the rattan after straightening against a force that would cause the rattan housed in the hole to return to its curved shape before straightening, and the tubular body being configured to be switchable between a shape in which parts of its longitudinal direction overlap each other and a shape in which it is stretched linearly.

[0008] Thus, the rattan straightening device of the present invention comprises a tubular body with a longitudinally extending hole. The tubular body has a longitudinal dimension, an inner diameter of the hole, and bending rigidity sufficient to maintain the rattan's stretched shape after straightening, resisting the force that tends to return the rattan to its curved shape before straightening. With a tubular body constructed in this manner, for example, when rattan obtained in a ring-shaped state is stretched into a straight shape and placed in the hole of the tubular body, the force that tends to return the rattan to its original shape prevents the tubular body from deforming, and the rattan's shape after straightening can be maintained. Therefore, by placing the rattan in the hole of the tubular body for a predetermined period of time, the shape of the rattan can be easily straightened. Furthermore, in the rattan straightening device of the present invention, the tubular body is configured to be switchable between a shape in which portions of its longitudinal sides overlap each other and a shape in which it is stretched straight. By overlapping parts of the cylindrical bodies in the longitudinal direction, the longitudinal dimension can be significantly reduced (by half or less). This allows them to be easily stored in a bag or the like, making them easy to carry and mail. Of course, when in use, they can be used to straighten rattan by extending them in a straight line, so there is no problem with configuring them to be switchable in shape as described above.

[0009] In addition, in the rattan shape correction device of the present invention, the hole diameter of the cylindrical body may be 20 mm or more and 40 mm or less.

[0010] Although it varies somewhat depending on the type and size of the wickerwork, considering that the thickness (outer diameter) and number of rattan pieces used in this type of wickerwork are somewhat fixed, it is desirable that the inner diameter of the hole in the corresponding tubular body be 20 mm or more and 40 mm or less. By constructing a correction device using a tubular body with a hole with an inner diameter within this range, it is possible to enjoy a stable rattan shape correction effect regardless of the type and size of the wickerwork.

[0011] In addition, in the rattan shape correction device according to the present invention, the longitudinal dimension of the cylindrical body may be 600 mm or more and 1500 mm or less.

[0012] Although it varies somewhat depending on the type and size of the wickerwork, considering that the longitudinal dimensions of the rattan used in this type of wickerwork are somewhat fixed, it is desirable that the longitudinal dimension of the tubular body be 600 mm or more and 1500 mm or less. By constructing a correction device using a tubular body with holes of longitudinal dimensions within the above range, it is possible to enjoy a stable rattan shape correction effect regardless of the type or size of the wickerwork.

[0013] In addition, in the rattan shape correction device according to the present invention, the tubular body may be configured so that it can be switched to a shape in which the tubular body is stacked in parallel by bending it.

[0014] With this type of correction device, the cylindrical body can be folded and stacked, and then simply stretched by holding both longitudinal ends of the cylindrical body and pulling it out, easily and instantly returning it to a straightened shape. This makes it possible to quickly correct the shape of rattan.

[0015] In addition, in the rattan shape correction device of the present invention, the tubular body may be made up of multiple segments formed by dividing the tubular body longitudinally, and each segment may be configured to be mutually connected at its longitudinal end and to be able to be disconnected.

[0016] By configuring the cylindrical body in this way, the cylindrical body can be easily divided into multiple segments, and by arranging the segments in parallel, the device according to the present invention can be easily stored in a bag or the like in a compact state and carried around.

[0017] Furthermore, in the rattan shape correction device of the present invention, the tubular body may be divided longitudinally into a plurality of segments each having a different inner diameter, and the segments may be configured so that they can be switched between an overlapping form in which a segment with a relatively small inner diameter is housed within the inner periphery of a segment with a relatively large inner diameter, and a form in which they are connected to each other at their longitudinal ends.

[0018] By configuring the cylindrical body in this way, the cylindrical body can be easily extended and easily overlapped. Furthermore, by configuring the cylindrical divided bodies to overlap each other in the radial direction, the device according to the present invention can be made even smaller, further improving portability. [Effects of the Invention]

[0019] As described above, the rattan straightening tool of the present invention allows even beginners to easily straighten rattan from its original shape to a shape suitable for rattan weaving. In addition, by switching to a shape where the rattan pieces are stacked on top of each other, the tool can be made compact and easily carried or mailed. [Brief explanation of the drawings]

[0021] Hereinafter, the rattan shape correction device according to the first embodiment of the present invention will be described with reference to the drawings.

[0022] Fig. 1 shows a plan view of a rattan shape correction tool 10 in a first form according to a first embodiment of the present invention. Fig. 2 shows a plan view of a second form of the shape correction tool 10 shown in Fig. 1. As shown in Figs. 1 and 2, the rattan shape correction tool 10 according to this embodiment is a tool for bundling and straightening rattan 1 (shown by a two-dot chain line in Fig. 1) used in rattan weaving, and includes a tubular body 12 having a hole 11 passing through in the longitudinal direction.

[0023] The cylindrical body 12 has a longitudinal dimension L, an inner diameter dimension D1 of the hole 11, and bending rigidity that are sufficient to maintain the stretched shape (the shape shown in Figure 3(b)) of the rattan 1 after straightening against the force that causes the multiple rattan 1 contained in the hole 11 to return to the curved shape (the shape shown in Figure 3(a)) before straightening.

[0024] Furthermore, the cylindrical body 12 is configured to be switchable between a linearly extended form (first form shown in FIG. 1 ) and a form in which longitudinal portions thereof are overlapped with each other (second form shown in FIG. 2 ). In this embodiment, the cylindrical body 12 is configured to be bent so that longitudinal portions 12a, 12a... of the cylindrical body 12 are overlapped in parallel with each other. In this case, the cylindrical body 12 has bent portions 12b (two portions in FIG. 2 ) formed by compressing the cylindrical body 12 in the radial direction, and can be folded back once or multiple times via the bent portions 12b while longitudinal portions 12a of the multiple cylindrical bodies 12 extend parallel to each other.

[0025] Here, the shapes of the outer peripheral surface 12c and the inner peripheral surface 12d of the cylindrical body 12 are in principle arbitrary, and for example, in this embodiment, both the outer peripheral surface 12c and the inner peripheral surface 12d have a cross-sectional shape of a perfect circle with a constant diameter dimension (see Figure 4).

[0026] In this embodiment, the cylindrical body 12 is provided with a dividing portion 13 that divides the cylindrical body 12 in the radial direction. The dividing portion 13 divides the cylindrical body 12 from the outer peripheral surface 12c to the inner peripheral surface 12d of the cylindrical body 12 and over the entire longitudinal length of the cylindrical body 12. This allows the cylindrical body 12 to be opened in the circumferential direction at the position of the dividing portion 13 (the state shown by the two-dot chain line in FIG. 4), making it easy to introduce the rattan 1 into the hole portion 11.

[0027] The inner diameter dimension D1 of the hole portion 11, which becomes the hole diameter of the cylindrical body 12, can be any dimension as long as the rattan 1 can maintain its stretched shape (the shape shown in Figure 3(b)) after straightening when the rattan 1 is introduced into the inner circumference of the hole portion 11, and is set, for example, to be 20 mm or more and 40 mm or less, and preferably 25 mm or more and 35 mm or less.

[0028] The longitudinal dimension L of the cylindrical body 12 can be any dimension as long as it can maintain the stretched shape (the shape shown in Figure 3(b)) of the rattan 1 after straightening when the rattan 1 is introduced into the inner circumference of the hole portion 11, and is set, for example, to be not less than 600 mm and not more than 1500 mm, and preferably not less than 750 mm and not more than 1200 mm.

[0029] The bending rigidity of the cylindrical body 12 is determined not only by the inner diameter dimension D1 and longitudinal dimension L of the cylindrical body 12, but also by the outer diameter dimension D2 of the cylindrical body 12 and the material of the cylindrical body 12, and is set to a value large enough to maintain the stretched shape (the shape shown in Figure 3(b)) of the rattan 1 after straightening when the rattan 1 is introduced into the inner circumference of the hole portion 11.

[0030] On the other hand, in this embodiment, it is preferable to set the upper limit of the bending rigidity of the cylindrical body 12 to a level at which a bent portion 12b is formed by bending the cylindrical body 12. Furthermore, it is preferable to select a material for the cylindrical body 12 so that after the bent portion 12b is formed by bending, the bent portion 12b disappears as the bending is released and the cylindrical body 12 can return to its pre-bending shape (the linearly stretched shape shown in FIG. 1). One example is a foamed resin.

[0031] The specifications of the rattan 1 assumed to be the subject of correction by the shape correction device 10 having the above configuration are, for example, as follows: The assumed outer diameter of the rattan 1 is 1.5 mm or more and 3.0 mm or less, the assumed longitudinal dimension of the rattan 1 is 600 mm or more and 1500 mm or less, and the assumed number of rattan 1, in other words, the number of rattan 1 assumed to be used in one rattan weaving work is 20 or more and 50 or less.

[0032] Next, an example of a method for straightening the shape of the rattan 1 using the rattan straightening tool 10 having the above-described configuration will be described.

[0033] First, as shown in FIG. 1, a shape correction device 10 is prepared in which a tubular body 12 is stretched linearly (first shape), and rattan 1 to be corrected is also prepared. When purchased, this rattan 1 is in a circularly wound shape as shown in FIG. 3(a). A predetermined number of rattan 1 in this shape are prepared and softened by soaking them in water for a predetermined time (e.g., on the order of several tens of seconds to several minutes). The softened rattan 1 is then stretched linearly and introduced into the hole 11 of the tubular body 12 in the first shape (the state shown in FIG. 1). At this time, the tubular body 12 may be opened circumferentially from the part where the dividing portion 13 is provided, as shown in FIG. 4, to introduce the predetermined number (plurality) of rattan 1 into the hole 11. Then, after the rattan 1 introduced into the hole 11 is held on the inner peripheral surface of the hole 11 (i.e., the inner peripheral surface 12d of the cylindrical body 12) for a predetermined time (for example, on the order of several minutes to several dozen minutes), the rattan 1 is removed from the cylindrical body 12. Finally, by drying it for a predetermined time (for example, on the order of several hours to half a day), rattan 1 for wickerworks is obtained.

[0034] As described above, the rattan shape correction device 10 according to this embodiment is provided with a tubular body 12 having a hole 11 penetrating in the longitudinal direction, and this tubular body 12 has a longitudinal dimension L, an inner diameter dimension D1 of the hole 11, and bending rigidity that are sufficient to maintain the straightened shape of the rattan 1 after correction (here, the straightened shape includes not only a shape stretched along a perfect straight line, but also a shape stretched straight with some curvature) against the force that tries to return the rattan 1 introduced into the hole 11 to its curved shape before correction. With a tubular body 12 configured in this way, for example, when rattan 1 obtained in a rolled-up state is stretched straight and placed in the hole 11 of the tubular body 12, the tubular body 12 will not deform due to the force that tries to return the rattan 1 to its original shape, and the shape of the rattan 1 after correction can be maintained. Therefore, by storing the rattan 1 in the hole 11 of the tubular body 12 for a predetermined time, the shape of the rattan 1 can be easily corrected. Furthermore, in the shape correction device 10 according to this embodiment, the above-mentioned tubular body 12 is configured to be switchable between a first configuration in which the tubular body 12 is linearly extended and a second configuration in which its longitudinal portions 12a are overlapped with each other. As a result, for example, when carrying the shape correction device 10, the longitudinal dimension of the tubular body 12 can be significantly shortened (to one-third of the extended dimension in this embodiment) by placing the longitudinal portions 12a of the tubular body 12 in the overlapped configuration (the configuration shown in FIG. 2). This allows the shape correction device 10 to be easily stored in a bag or the like, enabling smooth portability. Of course, when in use, the tubular body 12 can be used to correct the shape of the rattan 1 by placing it in the first configuration in which the tubular body 12 is linearly extended. Therefore, there is no problem with configuring the shape changeable as described above.

[0035] Although the first embodiment of the present invention has been described above, the rattan shape correction device according to the present invention is not limited to the above-mentioned exemplary form, and can take any form within the scope of the present invention.

[0036] Fig. 5 shows a plan view of a rattan body shape correction device 20 in a first form according to a second embodiment of the present invention. Also, Fig. 6 shows a plan view of the body shape correction device 20 shown in Fig. 5 in a second form. As shown in Figs. 5 and 6, the body shape correction device 20 according to this embodiment differs from the first embodiment shown in Fig. 1 etc. in that the tubular body 21 is made up of a plurality of divided bodies 22 formed by dividing the tubular body 21 in the longitudinal direction.

[0037] More specifically, the segments 22 are configured to be mutually connectable and disconnectable at one or both longitudinal ends. That is, one longitudinal end of at least some of the segments 22 is provided with a large-diameter fitting portion 23 whose inner diameter is larger than the inner diameter D1 of the segment 22 body and which can fit with the outer circumferential surface of the longitudinal end of an adjacent segment 22. Therefore, by fitting one longitudinal end of a segment 22 with a constant outer diameter D2 into this large-diameter fitting portion 23, adjacent segments 22 in the longitudinal direction can be connected to each other.

[0038] In this embodiment, two of the three segments 22 have large-diameter fitting portions 23 at one longitudinal end. The remaining segment 22 has constant outer diameter D2 and inner diameter D1 along its entire longitudinal length (see FIG. 5). Therefore, in this case, segments 22 having large-diameter fitting portions 23 are arranged on both sides of a segment 22 with a constant inner diameter, and the three segments 22 can be interconnected by fitting one longitudinal end and the other longitudinal end of the segment 22 with a constant outer diameter into the large-diameter fitting portions 23 of each segment 22. Because the inner diameter D1 of the hole 24 of each segment 22 is the same, the inner diameter of the tubular body 21 in the connected state (the state shown in FIG. 5) is constant along its entire longitudinal length.

[0039] As in the first embodiment, the bending rigidity of the divided body 22 only needs to be large enough to maintain the stretched shape (shown in FIG. 3(b)) of the rattan 1 after straightening when the rattan 1 is inserted into the inner periphery of the hole 11, and the divided body 22 is made of an inexpensive resin such as polyvinyl chloride. The same applies to the divided bodies 32 to 34 of the third embodiment described later.

[0040] According to the shape correction appliance 20 configured as above, when not in use for correction, the shape correction appliance 20 can be easily shrunk by releasing the connection between the segments 22 and arranging them, for example, in parallel, as shown in Fig. 6. Furthermore, there is no need to worry about the shape correction appliance 20 returning to its original shape (linearly stretched shape) due to elasticity, as in the shape correction appliance 10 according to the first embodiment.

[0041] Fig. 7 shows a plan view of a rattan shape correction device 30 in a first form according to a third embodiment of the present invention. Fig. 8 shows a plan view of a second form of the shape correction device 30 shown in Fig. 7. As shown in Figs. 7 and 8, the shape correction device 30 according to this embodiment is the same as the second embodiment shown in Fig. 5 etc. in that the tubular body 31 is composed of a plurality of divided bodies 32 to 34 obtained by dividing the tubular body 31 in the longitudinal direction, but differs in that the divided bodies 32 to 34 can fit together to take an overlapping form.

[0042] That is, in this embodiment, the multiple divided bodies 32 to 34 constituting the cylindrical body 31 are configured to be switchable between a second form (form shown in Figure 8) in which the divided body 33 (34) with a relatively small inner diameter dimension D12 (D13) is accommodated within the inner periphery of the divided body 32 (33) with a relatively large inner diameter dimension D11 (D12), and overlap each other, and a first form (form shown in Figure 7) in which the divided bodies are connected to each other at their longitudinal ends.

[0043] Therefore, in this case, the inner diameter dimensions D11, D12 and outer diameter dimensions D21, D22 of the hole 32a of the first segment 32 and the hole 33a of the second segment 33 are set to predetermined sizes so that the first segment 32, which has the smallest inner diameter dimension D11, can be accommodated inside the second segment 33, which has the second smallest inner diameter dimension D12. Also, the inner diameter dimensions D12, D13 and outer diameter dimensions D22, D23 of the hole 33a of the second segment 33 and the hole 34a of the third segment 34 are set to predetermined sizes so that the second segment 33, which has the second smallest inner diameter dimension D12, can be accommodated inside the third segment 34, which has the largest inner diameter dimension D13.

[0044] The other longitudinal end of the first segment 32 is provided with a pair of protrusions 35 that protrude radially outward and are adapted to fit into a pair of grooves 36 provided on the inner periphery of the second segment 33. This allows the first segment 32 to be slidably connected to the second segment 33 in the longitudinal direction, and the protrusions 35 engage with the end faces of the grooves 36 in the axial direction, thereby preventing the first segment 32 from slipping out of the second segment 33 (see FIG. 7). Similarly, the other longitudinal end of the second segment 33 is provided with a pair of protrusions 37 that protrude radially outward and are adapted to fit into a pair of grooves 38 provided on the inner periphery of the third segment 34. This allows the second segment 33 to be slidably connected to the third segment 34 in the longitudinal direction, and the protrusions 37 engage with the end faces of the grooves 38 in the axial direction, thereby preventing the second segment 33 from slipping out of the third segment 34 (see FIG. 7).

[0045] According to the shape correction device 30 configured as above, when not in use for correction (such as when carried), the divided bodies 32 and 33 having relatively small inner diameters D11 and D12 can be accommodated inside the divided bodies 33 and 34 having relatively large inner diameters D12 and D13, thereby forming a shape in which they overlap each other in the radial direction, as shown in Fig. 8. Therefore, the overall dimensions can be made even smaller than those of the shape correction device 20 according to the second embodiment. [Explanation of symbols]
