Description

  The present invention relates to a cylindrical instrument for a clothes-drying bar that can be improved in the clothes-drying function by being attached to the clothes-drying bar.

  Since the clothes drying work is a daily work, many proposals have been made to improve the work efficiency and the clothes drying function. In particular, there are many proposals regarding appliances used together with clothes-drying rods such as clothes-drying baskets and ropes for clothes-drying, and in particular, there are very many proposals for appliances for improving the function as a hanger hanger. For example, Patent Literature 1, Patent Literature 2, Patent Literature 3 and the like have been proposed for a laundry rod, and Patent Literature 4, Patent Literature 5 and the like have been proposed for a laundry rope.

  The problem is that the hanger may be dropped by the wind, or the laundry may move sideways by providing a structure such as a hole, groove, etc. that can fix the hanger to the equipment attached to the clothes bar. The aim is to eliminate problems such as close contact and entanglement, resulting in a decrease in drying efficiency.

  However, these are not intended for the “drying work in which clothes or clothes hangers are hung on a clothespin or the like and fixed”, which is the most commonly performed clothes drying work on a daily basis. However, even in the above case, many problems such as the tangled laundry with clothespins or the removal of clothespins with the laundry fixed due to the wind have been recognized on a daily basis. Nevertheless, there has been no proposal in the past that can solve the above-mentioned problems that occur when clothes drying is performed using clothespins and improve the clothes drying function.

  On the other hand, in the field of flagpoles, flagpoles with no flag entangled have been proposed. For example, a flag pole that prevents the flag from being entangled has been proposed by providing the flag pole with a structure that holds the flag on a cylindrical body that is rotatably fitted to the shaft rod (Patent Document 6). There was nothing about the clothes bar with such a structure.

Japanese Utility Model Publication No. 62-136992 No. 3062587 Japanese Patent No. 2829263 Japanese Utility Model Publication No. 02-116291 Japanese Utility Model Publication No. 57-179390 JP 2005-122029 A

  As previously mentioned, the appliances that have been proposed in the past do not assume the most frequently performed "hanging clothes hanger with laundry or laundry fixed to a clothespin with clothespins". Absent. For example, although the hanger fixture described in Patent Document 2 has a cylindrical shape, it has a structure in which free rotation without bias, which is an important feature of the product of the present invention described later, is difficult. In other words, the inner peripheral side has a shape in which the chevron part and the arc part are connected, and the chevron part is described as “upper part”, so it is assumed that the chevron part is used as the upper part only as a hanger fixture. It has a structure.

  Moreover, the inner peripheral side of the hanger hook of patent document 3 is also a structure used in the use aspect provided with the protrusion part for preventing the rotation and side slip of a cylindrical instrument by friction-contacting with the clothes-drying basket.

  On the other hand, in one embodiment of the hollow tube used in the clothes hanger hanging rope of Patent Document 4, and in the pipe itself used by penetrating the chain and rope of Patent Document 5, there is a space between the rope and the like. In addition, a structure that hinders free rotation of pipes, etc. is not recognized. However, in the first place, it is considered that the rope and the pipe through which the chain that is considered to have a lot of contact friction is difficult to rotate freely due to the rope etc. being bent, etc., and the example shows the use as a hanger hook. It ’s just that.

  Patent Document 6 is an invention of a flagpole, which has a different structure and solves various problems caused when clothes and hangers hung on clothes are fixed with clothespins and dried to improve the clothes drying function. There is no mention or suggestion about what can be done.

  In other words, in order to improve the clothes drying function when clothes or hangers hung on clothes are fixed to clothespins such as clothespins with clothespins and dried. No proposal has yet been made. The “drying function” in the present invention means that the laundry fixed with the clothespin does not get entangled with the clothespin by the wind and is easy to unwind even if it is turned up and caught, and prevents the clothespin from coming off. Refers to function.

  That is, when a laundry or a hanger hung on a laundry is hung on a clothes-pick and fixed with clothespins, the clothes that are swung by the wind are prevented from getting entangled and caught on the clothes-drying basket. The object is to provide a tool for a clothesline. In addition, if the laundry continues to be entangled with the laundry basket, the laundry will be wrinkled, and the drying efficiency and sterilization effect (sun drying effect) will also be reduced. However, it is an object of the present invention to provide a device for providing clothes for a clothes bar that solves such problems.

  It is another object of the present invention to provide an unprecedented apparatus for a clothesline bar that can provide the above-mentioned useful effects even though the clothes drying work itself is a work that is not different from the work that is normally performed.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that the above-mentioned clothes drying function is improved by using an instrument having a specific structure by fitting it to a clothes-drying bar. The invention has been completed.

  That is, the present invention is a tubular device for externally fitting to a clothes-drying rod to improve the clothes-drying function, and has a structure that can freely rotate around the clothes-drying rod as an axis without being biased around the circumference. The cross-sectional shape of the portion of the inner wall surface of the cylindrical device that contacts the clothes bar is a perfect circle or regular polygon that may have an uneven portion, and the circumference of the cross-sectional shape of the outer wall surface of the cylindrical device is continuous. More than two-thirds of them are a perfect circle, a polygon, or a part thereof, and the bus bar of the “surrounding two-thirds of surroundings” portion of the outer wall surface of the cylindrical instrument is the cylinder. A cylindrical instrument characterized by being parallel to the rotation axis of the cylindrical instrument and having both end openings of the cylindrical instrument perpendicular to the rotational axis of the cylindrical instrument. is there.

  Further, the present invention provides a concentric circle or concentricity in which the above-mentioned “circular or polygonal shape” in the cross-sectional shape of the outer wall surface of the cylindrical instrument has the same center as that of the regular circle or regular polygon constituting the cross-sectional shape of the inner wall surface The above-mentioned cylindrical instrument having a polygonal shape is provided.

  In addition, the present invention provides the above-described cylindrical instrument in which the entire circumference of the cross-sectional shape of the outer wall surface of the cylindrical instrument is a perfect circle or a polygon.

  In addition, the present invention provides the above-described cylindrical appliance, wherein the clothes drying function is a function that is exhibited when the laundry or the clothes hanger is hung on the cylindrical appliance and fixed with the clothespin. Is.

  In addition, the present invention provides the above-described cylindrical instrument in which the inner wall surface of the cylindrical instrument is configured and processed so that mold does not easily occur. That is, the cylindrical instrument of the present invention is usually used while attached to a clothes-drying rod, but it may become a problem when used while attached for a long period of time. The present invention provides a tubular device configured and / or treated to prevent mold generation.

  In addition, the present invention has a structure and treatment that hardly generates mold, and by forming the cylindrical instrument with a material having a high ultraviolet transmittance, generation of mold is suppressed by the effect of ultraviolet rays, and The cylindrical instrument which has suppressed generation | occurrence | production of mold | fungi by giving an antibacterial process to the inner wall surface of a shaped instrument.

  Moreover, this invention provides said cylindrical instrument whose length of one cylindrical instrument is 1 cm-50 cm. This length is set from the width necessary for fixing the laundry with clothespins. Since the length actually used is also a length that is appropriately selected depending on the size and type of the laundry, it includes an aspect in which a plurality of cylindrical appliances of several types are combined.

  In addition, the present invention provides the above-mentioned cylindrical appliance having a structure in which the outer wall surface of the cylindrical appliance is treated to prevent the skid of the laundry or the hanger hung on the laundry and / or has a structure for preventing the skidding. To do. Specifically, the outer wall surface is coated with a material having a non-slip effect, such as rubber, on a part or all of the outer wall surface, knurled, or provided with a non-slip protrusion, or on the outer wall surface. The present invention provides a cylindrical instrument having a groove structure, or a cylindrical instrument having a plurality thereof.

  Moreover, this invention provides said cylindrical instrument used with the fastener which suppresses the horizontal movement along the clothes bar of a cylindrical instrument. The cylindrical instrument of the present invention can be used with one or any number attached to the clothes-drying bar as required, but in this case, one cylindrical instrument is used so that the cylindrical instrument does not move horizontally. The horizontal movement of the cylindrical instrument is suppressed by installing fasteners at both ends of the tube or at both ends when a plurality of cylindrical instruments are lined up or at the other end if there is a convex part attached to the clothes bar on one side It is preferable that it is the shape to do.

  According to the present invention, the above-mentioned problems are solved, the above-mentioned problems are solved, and the cylindrical structure is designed so that it can be freely rotated without being biased around the circumference with the clothes-drying rod as an axis. The effect is exhibited when the laundry is usually hung on a clothespin and fixed with a clothespin. Conventionally, even when the laundry swung in a strong wind is entangled with the clothespin many times, the cylindrical appliance of the present invention rotates with the laundry and clothespin, so it blows up with the wind The laundry that has been turned upside down on the clothes-drying bar falls to the opposite side without overlapping, and rotates once to return to its original state. Furthermore, even if it receives a wind, it repeats and does not get entangled. In addition, even when the beaten laundry is caught on the clothes-drying bar, the cylindrical utensils and the clothespins are shaken so that the laundry is shaken off.

  Therefore, since the laundry does not overlap and always keeps the hanging state, the drying efficiency is improved, and wrinkles and shape loss are not caused. And since a load is not applied to a clothespin, it is hard to remove a clothespin.

  It is extremely difficult to remove the entanglement of the laundry once entangled, particularly when it is still wet. However, the use of the cylindrical appliance of the present invention saves time and labor for repairing the laundry. In addition, people who use the clothes-drying bar instead of a dryer expect the sterilization effect of sunlight by ultraviolet rays, so they will prevent tangling and irradiate the entire laundry with sunlight. Has a remarkable effect. By improving the above functions, it is possible to improve the drying efficiency and sterilization efficiency (sun drying efficiency) of the laundry, and to exhibit many effects such as the laundry being less likely to be wrinkled.

  The cylindrical instrument of the present invention has a cylindrical structure designed so that it can freely rotate around the clothes-drying bar and is free from all-around bias, and when the hanger hanging on the laundry is fixed to the product of the present invention with a clothespin In addition, the same effects as the above-mentioned laundry such as improvement of the drying function are recognized. As a result of the above, the present invention has an effect that the drying time of the laundry can be shortened and the state of the laundry after drying becomes a clean state without wrinkles.

  Furthermore, if the cylindrical instrument itself or the inner wall surface of the cylindrical instrument is constructed and processed so that mold does not easily occur, the occurrence of mold on the inner wall surface of the instrument is suppressed even when it is permanently attached to the clothes-drying bar. Therefore, it has the effect that it is easy to maintain cleanliness.

  In addition, since the length can be designed freely, there is no particular limitation. For example, if the length of one cylindrical instrument is in the range of 1 cm to 50 cm, the free rotation that is a feature of the cylindrical instrument of the present invention is possible. It is easy to remove and the laundry is easy to fix with clothespins. The present invention has an effect that a plurality of cylindrical instruments having various lengths can be selected in accordance with the use mode. Furthermore, the twisting of the laundry caused by the inclination of the clothespin is corrected, wrinkles and elongation are prevented, and the marks of the clothespin are hardly made.

  In addition, by making the openings at both ends perpendicular to the rotation axis, when used with multiple tubes, the adjacent openings are always parallel even when the cylindrical instrument is rotated separately, and the rotation is mutually It also has the effect of making free rotation easier without hindering.

  Also, the outer wall surface can have a treatment or structure for preventing side slipping, and such a cylindrical instrument can be used to place laundry under a clothes-drying bar at a location protruding outward from a clothes-bar hanging tool, a hook, etc. Even when they are stacked and fastened, they are less likely to come off, the laundry is less likely to be displaced, and are less likely to wrinkle and quicker to dry than when there is no skid prevention mechanism. Further, when the groove is provided as an anti-skid structure, it has the effect of preventing the hanger from slipping particularly when the hanger is hung on the groove.

  When used with a fastener that suppresses horizontal movement of the cylindrical appliance along the clothes bar (hereinafter simply abbreviated as “clamp”), in addition to the effect that the cylindrical appliance does not fall out of the clothes bar, The product of the present invention can be applied to any part of the entire length. Moreover, suppressing the horizontal movement of the cylindrical appliance also has an effect of suppressing the entanglement of the laundry fixed to the cylindrical appliance.

  Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of the tubular device 1 of the present invention that is externally fitted to a clothes-drying rod 2. A cylindrical instrument 1a whose outer wall surface 13 has a circular shape is externally fitted to the clothes bar 2 and is fixed in a state in which horizontal movement is suppressed by the two fasteners 3. The cross-sectional shape of the inner wall surface 12 of the cylindrical instrument 1a is a perfect circle, and it has a structure that allows free rotation around the clothes-drying bar 2 without being biased all around. Here, the “clothes bar” in the present invention refers to a bar that does not bend freely for drying objects. Further, the “cross-sectional shape” means a cross-sectional shape when the cylindrical instrument 1 is cut perpendicularly to the rotation axis, and the same applies hereinafter.

  FIG. 4A shows a cross-sectional view taken along the line AA in FIG. Although the cross-sectional shape of the outer wall surface 13 of the cylindrical instrument 1a is not particularly limited, it is a perfect circle in FIG. 1 and is a concentric circle having a center in common with the perfect circle constituting the cross-sectional shape of the inner wall surface 12. That is, the distance between the inner wall surface 12 and the outer wall surface 13 of the tubular instrument 1a (the thickness of the tubular instrument 1a) is substantially the same over the entire circumference. By doing so, the tubular instrument 1a is structured such that the free rotation can be made more smoothly with the clothes-drying rod 2 as an axis and without being biased all around.

  In FIG. 1, there is a gap between the leftmost tubular instrument 1 a and the fastener 3 for explanation, but this gap is not particularly limited, but a smaller one is preferable.

  FIG. 2 is also a perspective view showing an embodiment of the cylindrical instrument 1a of the present invention externally fitted to the clothes-drying bar 2, and the cylindrical instrument 1a is externally fitted to the clothes-drying bar 2. FIG.

  FIG. 3 is a perspective view showing an embodiment of the tubular device 1 of the present invention that is externally fitted to the clothes bar 2. A cylindrical instrument 1b whose outer wall surface 13 has a concentric polygonal cross section is fitted on the clothes bar 2 and is fixed in a state where horizontal movement is suppressed by the two fasteners 3. FIG. 4B shows a cross-sectional view taken along arrow BB in FIG. The cross-sectional shape of the inner wall surface 12 of the cylindrical instrument 1b is a perfect circle, and it has a structure that can freely rotate around the clothes-drying bar 2 without being biased all around.

  Here, the cross-sectional shape of the outer wall surface 13 being “concentric polygon” means that it is a polygon having a center in common with “a regular circle or polygon that forms the cross-sectional shape of the inner wall surface 12”. The “center of the polygon” in the present invention means the “center of gravity of the polygon”. The polygon is not particularly limited, but is preferably a regular polygon having rotational symmetry for the tubular device 1b of the present invention.

  The cross-sectional shape of the inner wall surface 12 of the cylindrical instrument of the present invention is preferably a perfect circle as described above, but may be a polygon. Such a polygon is not particularly limited, but is preferably a pentagon or more, more preferably a decagon or more, and particularly preferably a decagon or more. It is essential for the polygon to be a regular polygon in order to increase the number of contacts with the outer wall surface 15 of the clothes-drying bar or to realize smooth rotation. When the cross-sectional shape of the inner wall surface 12 and the cross-sectional shape of the outer wall surface 13 of the cylindrical instrument of the present invention are both polygonal, there is no particular limitation, but it is preferable that they are similar to each other. A regular polygon is particularly preferable.

  It is also preferable to provide a plurality of concave and convex portions that circulate around the inner wall surface 12 to reduce the friction by reducing the contact area with the clothes-drying rod 2 and to make it easier to rotate. In addition, when there is no drainage hole with the "circumferential irregularities", rainwater accumulates in the concave portion, and it may be difficult to flow down, but by providing the concave and convex portion in a spiral shape, the concave portion does not close Since it is connected to the opening and rainwater flows down by rotation, smooth rotation and drainage effect can be obtained. In such a structure, the cross-sectional shape of the inner wall surface 12 is uneven. Further, the cross-sectional shape of the recess is not particularly limited because it does not contact the clothes-drying bar 2 and does not affect the rotation.

  As described above, it is not always necessary to make the cross-sectional shape of the inner wall surface 12 uniform over the entire surface, and if the portion in contact with the clothes bar 2 has the above shape, smooth rotation of the cylindrical instrument 1 can be obtained. In addition, it is possible to unify the center of the cross-sectional shape of the portion of the inner wall surface 12 in contact with the clothes-drying bar 2 in a straight line and to make the inner diameter the same, while keeping the bus bar of the outer wall surface 13 parallel to the rotation axis, and the cylindrical instrument It is preferable for smoothly rotating 1.

Although there are various combinations of the inner wall surface 12 and the outer wall surface 13 of the cylindrical instrument, the following four types are particularly preferable.
(1) The inner wall surface is a perfect circle, the outer wall surface is also a perfect circle (2) The inner wall surface is a perfect circle, the outer wall surface is a polygon (3), the inner wall surface is a polygon, and the outer wall surface is a perfect circle (4 ) The inner wall is polygonal and the outer wall is also polygonal

  Of the cylindrical instruments 1, either “the cylindrical instrument 1a whose outer wall surface 13 has a circular cross section” or “the cylindrical instrument 1b whose outer wall surface 13 has a polygonal sectional shape” is usually preferred. Are used, but there is no problem even if they are used together. The “tubular instrument 1a” and the “tubular instrument 1b” may be collectively abbreviated as “tubular instrument 1”.

  Although the length of the one cylindrical instrument 1 is not specifically limited, The range of 1 cm-50 cm is preferable, The range of 2 cm-40 cm is more preferable, The range of 3 cm-30 cm is especially preferable. If the length of one cylindrical device 1 is too short, the fixing condition of the clothespins 4 may become unstable, or the number of the clothespins 4 may increase, and it may take time to wear them. Since a plurality of pieces of laundry 5 are hung on one cylindrical appliance 1, it may not be preferable.

  Even if a plurality of pieces of laundry 5 are hung on one long tubular appliance 1, the effect of the tubular appliance 1 can be obtained, but the individual laundry 5 turns in the opposite direction due to the difference in how it is beaten. May not be able to make full use of mutual free rotation. However, if the length is within the above range, it becomes easy to occupy one or more cylindrical utensils 1 with one piece of laundry 5, and the laundry 5 may be swung in different directions, or only one piece of clothespin. 2 Even if it is caught on the upper part, it rotates individually, so that the effect can be maximized without being obstructed by the other laundry 5.

  In addition, as will be described later, when one laundry 5 is fastened with a plurality of clothespins 4 or 4 ', the clothespin 4 or 4' is separated from the top of the tubular appliance 1 or the tube. It is preferable to fasten the laundry below the shaped device 1 (see FIG. 10). Since the clothespins 4 or 4 'move separately due to the separate rotation for each tubular device 1, the clothespins 4' with only one remaining on the top can be easily returned to the original position, or the clothespins This is because it is difficult to make a difference in angle to 4, and when the laundry 5 is hooked on the knob portion of one clothespin 4 or the like, it is inclined separately, so that the effect of returning to the original is improved. . Therefore, also from this point, the above-described range is preferable for the length of one cylindrical device 1.

  Both openings of the tubular instrument 1 are located relative to the rotation axis so that both ends are always in a constant position around the entire circumference even when the tubular instrument 1 is rotated in the orientation of the clothes bar 2 without being shaken in the horizontal direction. It is preferable that it is perpendicular in all directions. In this way, in particular, when a plurality of cylindrical appliances 1 are used in series without gaps, even if only one cylindrical appliance 1 rotates or adjacent cylindrical appliances 1 rotate in opposite directions, Smooth free rotation is possible without any influence other than friction caused by contact.

  The inner diameter of the cylindrical instrument 1 is not particularly limited as long as it is set to the clothes-drying bar 2 with a clearance described later, and also depends on the diameter of the clothes-drying bar 2, but is preferably 20 mm to 50 mm, more preferably 27 mm to 45 mm. 32 mm to 42 mm is particularly preferable. Although the thickness of the cylindrical instrument 1 is not specifically limited, 1 mm-7 mm are preferable, 1.5 mm-6 mm are more preferable, and 2 mm-5 mm are especially preferable. In the case of the cylindrical instrument 1b in which the cross-sectional shape of the outer wall surface 13 is a concentric polygon, the “thickness of the cylindrical instrument 1b” means the average of the thickest part and the thinnest part.

  4A is a cross-sectional view taken along the line AA in FIGS. 1 and 2, and FIG. 4B is a cross-sectional view taken along the line BB in FIG. 3. It is. The reason why the cross-sectional shape of the inner wall surface 12 of the cylindrical instrument is a perfect circle is to ensure smooth rotation of the cylindrical instrument 1. Moreover, even if the cross-sectional shape of the inner wall surface 12 of the cylindrical instrument is polygonal, it is only necessary to adjust the clearance between the clothes bar 2 and the like to ensure smooth rotation. In other words, the cylindrical instrument 1 of the present invention is designed so that it can freely rotate around the clothes-drying bar 2 without being biased all around.

  For smooth rotation, not only the shape but also the clearance from the outer wall surface 15 of the clothes-drying bar that serves as a shaft is important when the cylindrical instrument 1 rotates. In the present invention, the term “external fitting” is used. However, the cylindrical instrument 1 of the present invention is not necessarily used by being closely fitted to the outer wall surface 15 of the clothes-drying bar or being brought into full contact with the entire surface. It is better to provide a clearance between the inner wall surface 12 and the outer wall surface 15 of the clothes bar.

  The clearance is preferably 0.1 mm to 4 mm in terms of the distance from the outer wall surface 15 of the clothes bar when the inner wall surface 12 of the cylindrical instrument of the present invention is placed at equal distances from the outer wall surface 15 of the clothes bar. 0.2 mm to 3 mm is more preferable, 0.3 mm to 2 mm is particularly preferable, and 0.4 mm to 1 mm is still more preferable. If the clearance is too large or too small, the rotation will not be smooth, and particularly if the clearance is too large, problems such as the occurrence of a collision sound during rotation are likely to occur. However, what is important as the invention function of the cylindrical appliances 1 and 1b is that the rotation of the cylindrical appliance is ensured to such an extent that the laundry 5 that has received the wind naturally hangs down even if it is light. Therefore, if the function is substantially satisfied, the clearance may be outside the above range.

  In FIG. 4 (A), the cross-sectional shape of the outer wall surface 13 of the cylindrical instrument 1a is a perfect circle, and in FIG. 4 (B), the cross-sectional shape of the outer wall surface 13 of the cylindrical instrument 1b is a regular dodecagon. The cross-sectional shape of these outer wall surfaces 13 is such that the laundry 5 and the hanger 9 are directly fixed to the tubular appliance 1a and the tubular appliance 1b (both are abbreviated as “tubular appliance 1”) with the clothespins 4. It is designed as a shape suitable for. Currently, as a fixture for directly fixing the laundry 5 and the hanger 9 to the clothes-drying bar 2, many clothespins 4 having a shape suitable for sandwiching the clothes-drying bar 2 are commercially available. Therefore, for those suitable uses, the cross-sectional shape of the outer wall surface 13 is designed in consideration of the ease of pinching and the fixing strength of the laundry 5 when pinched.

  The shape of the polygon is not particularly limited, but in consideration of the ease of pinching as well as the influence on the thickness of the cylindrical device 1, a pentagon to an icosahedron are preferable, a hexagon to an hexagon are more preferable, Square to dodecagon is particularly preferable. From the same point as described above, the polygon is preferably a regular polygon, and more preferably a regular polygon. If it is made polygonal, the traces are likely to remain on the laundry 5, but the corner of the clothespin 4 has a corner that fits into the anti-slip irregularities inside the clothespin 4 than when it is made into a perfect circle. Depending on the shape, the degree of fixing is increased, the inclination of the clothespin 4 is suppressed, the outer wall is easy to distinguish from the clothespin 2 with a round outer wall, and the color is changed in units of surfaces. There are benefits. Needless to say, when the cross-sectional shape of the outer wall surface 13 is a polygon, each corner may be chamfered to form a smooth corner. Further, the side of the polygon is usually a straight line portion, but in the cylindrical appliance 1b, even if it is a slight curve portion, the laundry 5 is not easily marked, and a moderate degree of fixing with the clothespin 4 is possible. Is preferable. Further, for example, a shape in which a line segment and an arc are mixed, such as a curved upper portion in contact with the laundry 5 of the cylindrical appliance 1 and a flat portion in the other portion, is also preferable.

  As for the cross-sectional shape of the outer wall surface 13 of the cylindrical instrument 1 of the present invention, it is essential that two or more continuous two-thirds of the entire circumference or periphery is a perfect circle, a polygon, or a part thereof. In the figure, the entire circumference is a perfect circle or a polygon, but it is sufficient that two or more consecutive two-thirds around the cross-sectional shape of the outer wall surface 13 is a perfect circle or a polygon or a part thereof. If the upper part of the cylindrical appliance 1 that contacts the laundry 5 (that is, other than one-third of the connected periphery of the lower part that is not normally in contact with the laundry 5) has at least the shape described above, the laundry 5 Even if the clothespin 2 and the clothespin 2 are sandwiched together and fixed with the clothespin 4 used in a state where the lower part is opened, the range in which the clothespin 4 and the cylindrical appliance 1 are in contact (with the clothes 5 interposed) Since it becomes a shape, the effect of the present invention is obtained.

  In addition, it is essential that the generatrix of the above-mentioned “surrounding continuous two-thirds or more” portion of the outer wall surface of the cylindrical instrument 1 of the present invention is parallel to the rotation axis of the cylindrical instrument 1. is there. As a result, the outer diameter of the portion of “the entire circumference or the continuous two-thirds or more of the circumference” is unified, and the laundry 5 is not deformed. In addition, the degree of fixing with the clothespin 4 also increases. In addition, smooth rotation is possible without any bias in any part of the cylindrical instrument 1. Here, the “bus” refers to the shortest straight line when the periphery of the outer wall of the opening corresponding to the bottom surface and the periphery of the outer wall of the opening corresponding to the upper surface are connected when the cylindrical instrument 1 is a column. However, the following unevenness for preventing skidding is excluded from the above definition.

  The material of the cylindrical appliance 1a and the cylindrical appliance 1b is not particularly limited as long as it is strong enough to withstand the pinching of the clothespin 4 and can be molded, but it is hard, weatherproof, and more lightweight. Is suitable. Examples thereof include metals such as stainless steel and aluminum; plastics such as acrylic resin, polycarbonate resin, polyethylene resin, polypropylene resin, and polyester resin. Plastics are preferred to metals because they are lighter and have sufficient mechanical strength for the application of the present invention. Among them, the UV-transmitting acrylic resin has a high visible light transmittance, so that it is easy to check the stain on the inner wall of the cylindrical instrument 1 and the UV transmittance is high. Further, since it is lightweight, it can be used particularly preferably in the present invention.

  It is preferable that the cylindrical instrument 1 is configured to be homogeneous, that is, there are no holes, gaps, ribs, or the like in the thickness portion, and the cylindrical instrument 1 is uniformly filled with the material constituting the cylindrical instrument 1. Since the thickness is sufficiently thin, it is not necessary to make it so light, and if it is not homogeneous to the inside, the strength may be reduced and the manufacturing cost may be increased.

  It is preferable that the inner wall surface 12 of the tubular instrument 1 is constructed and processed so that mold does not easily occur. Here, since the structure / treatment that hardly generates mold is made of the cylindrical instrument 1 made of a material having a high ultraviolet transmittance or antibacterial treatment is particularly effective because mold is hardly generated. preferable. Ultraviolet light is transmitted by using a material with high ultraviolet transmittance, and exhibits antibacterial and antifungal effects. There is no particular limitation on the antibacterial agent for antibacterial treatment, and general-purpose agents can be used.

  It is preferable that the cylindrical instrument 1 is transparent in the wavelength region of visible light because dirt on the inner wall surface 12 can be visually observed. Colored and transparent is preferable because stains on the inner wall surface 12 of the cylindrical instrument can be visually observed. However, colorless and transparent is particularly preferable because dirt and the like on the inner wall surface 12 of the cylindrical instrument can be visually observed.

  Although the fastener 3 for suppressing the horizontal movement of the cylindrical instrument 1 of the present invention is not particularly limited, it usually remains installed for a long period of time, so a non-slip member such as rubber is provided on the inner wall side in contact with the clothes bar 2. It is preferable to use a fastener 3 of a type that can be firmly and permanently fixed by screwing, screwing or the like. In addition, the fastener 3 having a shape and a size that prevents the laundry 5 from being entangled with the fastener 3 is suitable for the present invention. Accordingly, the fastener 3 is preferably small and has little unevenness. However, if it is temporarily used as needed, it is also possible to use the clothespin 4, a rubber band, or the like as the fastener 3. In addition, if the single cylindrical instrument 1 is used as a spacer without fixing the laundry 5 just in case, it is possible to prevent the laundry 5 from being entangled with the fastener 3.

  FIG. 5 is a conceptual diagram of the principle of the present invention. When the cylindrical appliance 1 is subjected to strong wind with the laundry 5 fixed with the clothespins 4 (FIG. 5B), when the cylindrical appliance 1 is not used (FIG. 5A). In comparison, the laundry 5 is shown to explain the reason why the laundry bar 2 is less likely to get tangled.

  First, the problem in the clothes drying operation of “when not using the cylindrical appliance of the present invention” shown in FIG. That is, when the laundry 5 is dried, the clothespins 4 and the clothespins 4 'are sandwiched from the upper part of the clothespin (FIG. 5A), or fastened below the clothespin (FIG. 6A). )) Is normal. When the laundry 5 is blown in the wind in this state, one side piece or both side pieces of the laundry 5 are blown up and hung over the top of the clothes-drying bar 2 (for example, FIG. 5 (a ′): hooked state) Furthermore, it is often recognized that when a strong wind is received, the clothespin 2 is entangled (for example, FIG. 6A: entangled state). Then, the hooked state of FIG. 5 (a ') and the entangled state of FIG. 6 (a) are rarely resolved naturally by the wind blown thereafter.

  Moreover, since the drying efficiency of the laundry 5 in the entangled state is extremely deteriorated, it becomes extremely slow as compared with the case where the time until drying is not entangled. Moreover, in the state where it is caught as shown in FIG. 5 (a ') or entangled as shown in FIG. 6 (a), the laundry 5 tends to wrinkle. As a result, it dries out in a deformed state.

  On the other hand, in the case of FIG. 5 (b) using the tubular appliance 1 of the present invention, even if one side piece or both side pieces of the laundry 5 are blown up and caught on the clothes-drying bar 2, it blows further. Since the tubular instrument 1 and the clothespin 4 and the clothespin 4 'both move in the wind, they are shaken off from the top of the clothes bar 2 and return to the original hanging state (FIG. 5 (b): original State). Even if the laundry 5 is caught on the knob part of the clothespin 4 (FIG. 6C), the knob part falls down due to the weight of the laundry 5, so that the hook is released and the original state is restored. .

  Further, when the wind is strong, the cylindrical utensil 1 rotates together with the laundry 5 or the clothespin 4 or the clothespin 4 'that has been swung by the strong wind (FIG. 6B). Since it acts as if the applied rotational force is not received by clothespins or clothespins, it will be released, so the laundry 5 will be released to the opposite side of the blown up, and will make one rotation without being wrapped. Return and never get tangled.

  As described above, even if the laundry 5 is blown up onto the tubular appliance 1 or the clothespin 4 due to wind, the tubular appliance 1 is affected by the weight of the hooked laundry 5 or the wind force. If it is shaken, the catch is released, and it returns to its original state, and if it is a gust or strong wind, as described above, the laundry 5 fastened to the tubular device 1 with the clothespin 4 makes one rotation or Since it returns to the original after several rotations, it will return to the original state in any case.

  As described above, the “drying function” of the cylindrical appliance of the present invention is exhibited when the laundry 5 is fixed to the cylindrical appliance 1 with the clothespin 4 or the clothespin 4 ′. According to the same principle, the present invention is also exhibited when the hanger 9 on which the laundry 5 is hung is fixed to the tubular appliance 1 with the clothespin 4 in particular.

  7 (a), 7 (b), and 7 (c) show that the laundry 5 or the “hanger 9 on which the laundry 5 is hung” slides on the tubular device 1 on the outer wall surface 13 of the tubular device. It is a figure at the time of adding the function to prevent. FIG. 7A shows an example in which the outer wall surface 13 is coated with a member 10 having a high anti-slip effect such as rubber. The member 10 having a high anti-slip effect (hereinafter abbreviated as “anti-slip member 10”) is not particularly limited. However, in consideration of the environment for a clothes bar, one having excellent weather resistance and light resistance is preferable. For example, silicon rubber A low elastic body such as EVA resin can be preferably used. The anti-slip member 10 may be coated on the entire outer wall surface 13 or may be partially coated as long as the object of anti-slip is achieved.

  FIG. 7B shows an example in which the groove structure 11 is provided. The groove is not particularly limited as long as it has a width and depth suitable for a commercially available hanger 9. However, the groove width is preferably 1 to 15 mm, particularly preferably 5 to 10 mm, and the groove depth is 1 to 1. 8 mm is preferable, and 3 to 6 mm is particularly preferable. The number of grooves installed in one cylindrical device 1 is not limited to one, but in consideration of maintaining free rotation of the cylindrical device 1 that is the source of the inventive function of the present invention, Only one hanger 9 is preferably fixed to the tool 1. In order to prevent misuse, it is preferable that only one groove structure 11 is provided in one cylindrical device 1. Further, the position of the groove structure 11 is preferably provided at the center portion of the tubular device 1 in consideration of the weight balance when the hanger 9 is hung on the groove.

  It is also preferable to regularly provide slight protrusions in the form of dots or lines such as protrusions that circulate in the direction perpendicular to the rotation axis on the outer wall surface 13 of the cylindrical instrument in order to prevent skidding (not shown). It is also preferable to knurling the outer wall surface 13 of the cylindrical instrument. The projection width of the “projection that circulates in the direction perpendicular to the rotation axis” is not particularly limited, but is preferably 0.5 to 5 mm, and particularly preferably 1 to 3 mm. Further, the interval between the “projections that circulate in the direction perpendicular to the rotation axis” is not particularly limited, but is preferably 0.5 to 50 mm, particularly preferably 20 to 30 mm.

  The structure / physical properties of the outer wall surface 13 of the cylindrical appliance as described above are those that can prevent the skidding of the laundry 5, but by preventing the skidding, the outer wall 13 can be secured with the clothespin 4 '. It is possible to prevent the laundry 5 and the clothespins 4 'from coming off from the end of the tubular device 1.

  When the groove structure 11 is provided, when the hanger 9 is fixed, it is not necessary to use the clothespin 4 together with respect to the horizontal movement. However, considering the effect of improving the drying efficiency by preventing entanglement, it is preferable to fix the clothes hanger 9 with the clothespin 4 even when the hanger 9 is installed in the groove.

  Further, any one of the coating of the anti-slip member 10 and the groove structure 11 may be added to the cylindrical device 1, or a plurality of them may be added as shown in FIG.

  FIG. 8 is a perspective view showing an example of the cylindrical instrument 1 that can be opened and closed, which is used when the cylindrical instrument 1 cannot be inserted into the clothes bar 2. In this example, the joint on one side of the cylinder divided into two vertically is joined by the joining member 16 so that it can be opened and closed, and the meshing structure 18 is provided on the other joint. Even if it is the clothes-drying bar 2 which cannot be inserted by joining the meshing structure 18 after putting the tube-shaped instrument 1 in this state on the clothes-drying bar 2, even if it is the clothes-bar 2 which cannot be inserted, the tube-shaped instrument 1 Can be externally fitted. In this case, a joining member 17 with release paper having one end bonded in advance is prepared in the meshing portion, and after the meshing portion is firmly joined, it can be reinforced with the tape from which the release paper is peeled off. Also good.

  FIG. 8 shows an embodiment in which the hinge that exposes the protruding portion is not used so as not to affect the free rotation of the cylindrical appliance 1 without bias and the pinching of the clothespin 4. However, as long as the hinge can be used with a protrusion that does not protrude or a protrusion that does not affect the pinching of the clothespin 4, a connection may be made using the hinge.

  FIGS. 9A, 9 </ b> B, and 9 </ b> C show variations of the usage method when a plurality of cylindrical instruments 1 are externally fitted to the clothes-drying bar 2. FIG. 9A is an example in which the tubular device 1 is installed without gaps in the entire range excluding the hook portion 7 of the clothes bar hanging tool 6, and FIG. 9B is an arbitrary place using the fastener 3. In this example, an arbitrary number of tubular devices 1 are installed with a fastener 3 without gaps. The fastener 3 suppresses the horizontal movement of the tubular instrument 1.

  It is preferable that the fastener 3 is fastened with a margin to the extent that the free rotation of each of the plurality of tubular devices 1 is not hindered, and is not attached by pressing more strongly than necessary in the direction of the plurality of tubular devices 1. If it is pressed and tightened more than necessary, excessive friction is generated at the place where the cylindrical instruments 1 are in contact with each other, and the cylindrical instrument 1 may not move (rotate) separately.

  On the other hand, FIG. 9C is an example in which a plurality of cylindrical appliances 1 are installed in a state where a wide gap is generated between the cylindrical appliances 1 without using the fastener 3. In the installation method as shown in FIG. 9 (c), the tubular instrument 1 is irregularly moved horizontally by the influence of wind or the like. As a result, even in the installation method as shown in FIG. The cylindrical appliance 1 is used when a single cylindrical appliance 1 is used or a plurality of cylindrical appliances 1 are fixed to each other with the clothespin 4 so as to bring the cylindrical appliances 1 into close contact with each other. Compared with the case where it does not, since the clothes drying function improves much, the usage method of FIG.9 (c) is also one aspect | mode of this invention method.

  However, in the case of the usage method shown in FIGS. 9A and 9B, the cylindrical instrument 1 does not move horizontally, so that the clothes drying function such as the drying function is improved as compared with the method shown in FIG. 9C. From the above, a more preferable method of using the tubular instrument 1 of the present invention is to install the hanger 2 with no gap as shown in FIG. 9 (a), or as shown in FIG. 9 (b). It is a method of installing so that the cylindrical instrument 1 may not be horizontally moved using 3 as appropriate.

  FIG. 10 is a perspective view showing a state in which the laundry 5 and the hanger 9 are fixed to the tubular appliance 1 with the clothespins 4. It is preferable as a method of using the cylindrical appliance 1 that one laundry 5 is fixed across one or a plurality of cylindrical appliances 1. When a plurality of laundry items 5 are fixed to a single cylindrical instrument 1 with clothespins 4 and the like and the clothes are dried, the plurality of laundry items 5 do not move separately when receiving wind. In some cases, the free rotation of the laundry is hindered by the weight and movement of the laundry, and the effect of tangling the laundry 5 may be reduced.

  When one laundry 5 is fastened with a plurality of clothespins 4 or 4 ′, it is preferable that the clothespins are fastened to the tubular appliance 1 or below the tubular appliance 1, respectively. When one laundry 5 is fastened to one long tubular appliance 1 with, for example, two clothespins, one clothespin 4 is inclined by the wind and the angle between the two clothespins 4 is shifted. In some cases, one of the clothespins 4 ′ may not return directly under the clothes-drying bar 2, but it recovers from that state unless there is a large frictional repair between the cylindrical appliance 1 and the laundry 5. do not do. However, if one laundry 5 is fastened to, for example, two short cylindrical appliances 1 with two clothespins 4 respectively, the two clothespins 4 move separately, so that the above-mentioned friction is unnecessary ( Friction does not occur), and the angular difference of the clothespins 4 is naturally eliminated by the separate rotation of the tubular appliance 1. In addition, since the laundry 5 is tilted separately, for example, when the laundry 5 is caught on the knob portion of one of the clothespins 4 (FIG. 6c), the effect of returning to the original state is improved. As a result, wrinkles that occur when the laundry 5 is dried in a twisted state can be prevented.

  A suitable value for the length 14 of the tubular device 1 can be derived from the standard method of using the tubular device 1 described above. In other words, the length 14 to be included in one tubular device 1 needs to be at least larger than the width of the clothespin 4 for fixing the laundry 5, and is therefore 1 cm or more, preferably 2 cm or more. Further, the upper limit of the length 14 may basically be determined based on whether or not free rotation can be secured, and if it is the standard, there is a possibility that there is no problem even with 100 cm, for example. However, fixing a plurality of laundry items 5 to one cylindrical appliance 1 may impair free rotation as described above. Therefore, in consideration of the width of the laundry item 5, preferably 50 cm, more preferably 40 cm, should be the upper limit of the length 14 of the tubular device 1. A length of about 40 cm at the longest is suitable as a product because it is easy to supply and purchase.

  FIG. 11 is a view showing an example of a variation of the installation target of the cylindrical appliance 1 or the clothes-drying tool incorporating the cylindrical appliance 1. In other words, the “drying bar” in the present invention is not particularly limited as long as it is a bar that does not bend freely for drying, and a horizontal bar for drying a laundry on a clothesline, for example, a drying stand as shown in FIG. Examples include sticks and clothes poles. In the thing which bends softly freely, such as a clothesline and a clothesline rope, the free rotation of the cylindrical instrument 1 is inhibited. The “drying bar” in the present invention is not limited to one that does not bend at all, and may be slightly bent so that free rotation is not hindered.

  Basically, the cylindrical instrument 1 has a portion corresponding to a clothes-drying bar, and if it is a clothes-drying tool that is dried by receiving wind or light outdoors, the clothes-bar part of the clothes-drying tool is used regardless of the shape of the clothes drying tool. In addition, it is possible to improve the clothes drying function of the clothes drying tool provided with the tubular instrument 1.

  The object to be dried using the tubular instrument 1 is not particularly limited. However, there are clothes drying objects suitable as the objects of the present invention because of the inventive function of the present invention. Then, the relationship between improving the clothes drying function which is the invention function of the cylindrical appliance 1 and the kind of the laundry 5 is demonstrated.

  The concrete content of the improvement of the clothes drying function of the cylindrical appliance 1 is that the laundry 5 fixed with the clothespins 4 or 4 'is not wrapped around the clothesline by the wind and is easy to be unraveled even if caught. is there. And, by improving the above functions, the drying efficiency and sterilizing effect (sun drying effect) of the laundry 5 are improved, and further, the laundry 5 is less likely to be wrinkled and less likely to lose its shape. . In consideration of the above, among the laundry 5, what is considered to be easily tangled under the influence of the wind when the clothespin 4 is fixed to the clothespin 4 or 4 'and dried is particularly advantageous for the present invention. It is an object to receive. For example, towels, bath towels, sheets, blankets, shirts, T-shirts, sweaters, trainers, trousers and the like can directly receive the effects of the present invention.

  On the other hand, it is a normal method to fix small items of laundry 5 such as socks, gloves, underwear, etc. to a clothes-drying bar via a pincer. When the pinching tool on which the laundry 5 is hung is also fixed to the cylindrical appliance 1, the drying efficiency of the laundry 5 is improved by rotational movement or the like when wind is received. It can be said that the laundry 5 receives the effects of the present invention indirectly.

  As described above, the tubular instrument 1 of the present invention can prevent the laundry 5 fixed with the clothespins 4 or 4 'from being entangled with wind by being attached to the clothes-drying bar 2, and can be dried. It has many new and useful remarkable effects, such as shortening time, improving sterilization efficiency (sun drying effect), and allowing the laundry 5 to be dried without wrinkling or losing its shape. It is also widely used in commercial places such as.
