Description

  The present invention relates to a leg-opening prevention device, and in particular, a portable and convenient leg-opening prevention device that can effectively prevent both legs from opening when a user sits on a chair, etc., and has excellent fashionability when worn. It is about.

  When sitting on a chair or the like, especially when the posture is long, both legs may open unintentionally due to fatigue or relaxation of tension. Especially in the case of women, prevention of such a posture is desired compared to men. The demand is particularly strong when wearing skirts.

  In order to prevent such an open leg, several proposals have been made so far. The devices disclosed in Patent Documents 1 and 2 below use a band made of rubber fiber or the like that can be wound around a leg and wound in a roll shape when not in use.

  The device disclosed in Patent Document 3 is a substantially U-shaped thigh stabilization wearing device provided with L-shaped bent portions for supporting leg portions from both outer sides.

Japanese Utility Model Sho 62-129020 “Portable Women's Leg Prevention Belt” Japanese Patent Laid-Open No. 2000-199114 “Band that closes both feet” Utility Model Registration No. 3128187 “Thigh Stabilization Equipment”

However, in the belt-like tool proposed in Patent Documents 1 and 2, the entire circumference of both leg portions is wound and fixed with a hook-and-loop fastener or the like, so the accessory is inevitably too conspicuous as an accessory, and is fashionable There's a problem. Furthermore, wrapping and wearing easily associates wearing behavior that is required, such as wearing a supporter, and there is also a problem in fashionability and taste as an accessory.
Moreover, although the tool proposed by patent document 3 is not what is wound around a leg part, it cannot be said that it is scarcely fashionable and palatable, and carrying is not convenient.

  The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, and to be used as a new portable accessory that combines functionality, fashionability and taste, especially for women. Is to provide tools.

  As a result of studying the above problems, the inventors of the present application have found that the above problems can be solved by using a hard band that can be freely opened and closed, and have reached the present invention. That is, the inventions claimed or at least disclosed in the present application as means for solving the above problems are as follows.

(1) Two hard band members each having a curved portion are anti-spreading devices formed by overlapping the wide surfaces at the coupling end portions so as to be pivotable with respect to each other. The hard band member is formed so that the distance from the central position of the curved portion is longer than the open end which is the opposite end, so that both curved portions are located on the same side of the rotation plane. An anti-spreading tool characterized in that both hard band members are combined.
(2) The leg opening preventing device according to (1), wherein the hard band member has a substantially J-shape in which the curved portion and the straight portion are continuous.
(3) Of the two hard band members that are joined, the inner one is such that both the hard band members are superposed on the curved portion of the outer hard band member by rotation. It is formed, The leg prevention tool as described in (1) or (2) characterized by the above-mentioned.

(4) When both the hard band members are opened to the maximum, the distance between both open ends is 10% or more and 90% or less of the passing length of the present leg preventing device, (1 ) To (3).
(5) When the both hard band members are opened to the maximum, the distance between both open ends is 35% or more and 65% or less of the passing length of the present leg preventing device, (1 ) To (3).

  Since the leg opening preventing device of the present invention is configured as described above, according to this, both functionality, fashionability and preference can be satisfied. That is, the tool itself can effectively prevent the legs from being opened only by covering a part of the entire circumference of the legs instead of wrapping them.

  In particular, when the tool is mounted from the lower side so that the open end of the tool is on the front side of both legs, only a part of the tool is observed in appearance, so that the tool is not too conspicuous. Nevertheless, it has better fashion and taste than ever before.

  In contrast, the conventional technology is a simple band as a form, or a form that seems to be a design that emphasizes functionality, whereas the present invention proposes a new form as a problem solving means. The idea is based on its basic structure and has a lot of development possibilities for shapes, materials, patterns, colors, etc., and it has created a new market for portable accessories, especially for women. There is a high possibility of expansion.

The present invention will be described below with reference to the drawings.
FIG. 1 shows a basic configuration of a leg opening prevention device of the present invention, and is an explanatory view in plan view showing a state in which both hard band members are opened. Also,
2 is an explanatory diagram of an upper perspective view showing a state in which both hard band members of the leg opening preventing device of the present invention shown in FIG. 1 are opened,
FIG. 3 is an explanatory view in plan view showing a state in which both hard band members of the leg opening preventing device of the present invention shown in FIG. 1 are overlapped and closed.

  As shown in these figures, the leg opening preventing device 1 of the present invention is such that the hard band members 2A and 2B having the curved portions 6A and 6B are rotated with the wide surfaces overlapped at the coupling end portions 3A and 3B. It is a tool that is freely combined. The hard band member 2A is formed such that the coupling end 3A is longer than the open end 4A, which is the opposite end, from the central position 5A of the curved portion 6A. On the other hand, the hard band member 2B is also formed such that the coupling end 3B is longer than the open end 4B, which is the opposite end, from the central position 5B of the curved portion 6B. The main components of the hard band members 2A and 2B are such that both curved portions 6A and 6B are coupled to be located on the same side of the rotation plane.

  The hard band members 2A and 2B constitute the device 1 in a state in which they are rotatably coupled, and when attached to the leg of the user, the leg is naturally relaxed and outwards due to the open leg. As long as it can sufficiently withstand this force without deformation, its shape, material, dimensions, strength and other physical properties are not necessarily the same. In particular, regarding dimensions, different dimensions are naturally allowed in order to have a portable and convenient configuration as will be described later.

  The hard band member 2A and the like sufficiently withstand the lateral force at the time of such leg opening so that the leg can be effectively restrained by natural relaxation of the leg part when it is attached to the user's leg part, Any material, strength such as the thickness of the band and the width of the band surface, curvature of the curved portion, and the like may be used as long as the strength is such that deformation or breakage does not occur.

  In other words, the hard band member 2A of the device 1 of the present invention has the flexibility necessary for the method of winding the entire circumference of the leg portion and fixing it with fixing means such as a hook-and-loop fastener as in the prior art (Patent Documents 1 and 2). -It is not a variable band, but supports the user's leg from the side by the strength of the rigid band member itself without using a fixing means such as a hook-and-loop fastener or a button.

  The hard band member 2A, etc., which is the main part of the device 1 for preventing leg spread of the present invention, can be freely used by using an appropriate material from the viewpoint of material cost, manufacturing process, design development, product development / product development, etc. This can be formed. By combining these viewpoints, for example, ABS (acrylonitrile-butadiene-styrene copolymer) resin, polypropylene resin, and other appropriate synthetic resins can be suitably used as the material.

  In addition, it is desirable that the hard band members 2A and 2B are both formed of the same material from the viewpoint of the manufacturing process and cost, but it is also possible to combine them using different materials to form the device of the present invention. It is not excluded from the scope of the present invention.

  As shown in the figure, each of the hard band members 2A, 2B of the leg opening prevention device 1 has a substantially J-shaped side surface in which a curved portion 6A and the like and a straight portion 7A and the like are continuous. The two hard band members 2A, 2B are coupled to each other by appropriate coupling means 8 at the coupling end portions 3A, 3B.

  As the coupling means 8, for example, a screwing type can be suitably used, but in short, any means or member can be used as long as each rigid band member 2 </ b> A, 2 </ b> B can freely rotate around the coupling means 8. Any appropriate one can be used.

  As shown in FIG. 3, the leg opening preventing device 1 is configured such that the curved portion (6A) of the inner hard band member (2A in the drawing) is turned and the curved portion (6B) of the outer hard band member (2B) is rotated. It can be set as the structure which can be piled up on. With this configuration, when not in use, both the hard band members 2A and 2B can be closed and overlapped to reduce the overall size, which is convenient for carrying and storage.

4-6 is explanatory drawing which shows the use condition of the spread leg prevention tool of this invention, among these, FIG. 4 is the state in the middle of mounting | wearing operation | movement of this tool,
FIG. 5 shows a state in which the wearing operation of the tool is completed,
FIG. 6 shows examples of other mounting methods.

  As shown in FIGS. 4 and 5, the leg opening preventing device 1 is fitted around the legs L and L through the lower side of the user leg L with the knees aligned. The tool 1 holds the leg portions L and L in a state where the curved portions 6A and 6B are hung around a part of the front portion from the outside of both the leg portions L and L. Since the end portions of the curved portions 6A and 6B, that is, the open end portions 4A and 4B are directed inward with respect to the leg portions L and L, the distance between both knees can be pressed from the side to effectively prevent the legs from being opened. .

  As described above, in the leg opening preventing tool 1, the hard band members 2A and 2B are such that the coupling end 3A and the like are at a distance from the center position 5A and the like rather than the open end 4A and the like which are opposite ends. Is formed so as to be long, the present device 1 is not worn over the entire circumference of both leg portions L, L with the knees aligned, but a part thereof is opened.

  Therefore, it is not only easy to wear, but also there is no feeling of pressure because there is little pressure on the legs L, L, there is little fatigue, and it can be worn comfortably for a long time. Moreover, since it does not stand out more than necessary in appearance, and yet can exhibit a casual fashion, it is particularly preferable as a new accessory for women.

  As shown in FIG. 6, the leg opening preventing device 1 may be used by fitting it from above both leg portions L and L. According to this method, the situation where the legs are opened from the opening of both knees may be more effectively prevented. For example, when the sitting posture extends for a considerably long time, such as traveling on a railroad for a long time, the mounting methods shown in FIGS. 5 and 6 may be used while being appropriately changed.

  Since there are individual differences in the size around the leg and the size of each part of the leg, this tool may provide a plurality of molds that can accommodate a certain size range. Further, even the same type of device may be worn according to a site (for example, near the knee, or the lower leg, upper leg) that matches the leg size of the user.

  In the example shown in FIG. 4 and the like, the spread leg preventing tool 1 has a distance between the open end portions 4A and 4B when the hard band members 2A and 2B are opened to the maximum. The design is about 50%. However, the present invention is not limited to this. However, this value is desirably 10% or more and 90% or less in order to perform the function of the present device satisfactorily. Furthermore, if comprehensively considering the ease of wearing, the effect of preventing leg spread, and the like, it is more desirable to set the ratio between 35% and 65%.

  As described above, the material, shape, and other specifications of the hard band member 2A etc. of this tool can be freely formed, but the design aspect such as the specific shape, pattern, color, etc. Needless to say, it is within the scope of the present invention. In short, since the hard band member 2A and the like of the present invention only have to have the above-described configuration for exhibiting the above-described functions, for example, the shape of the wide surface is not limited to the rectangular shape, but is curved. Alternatively, a figure in which a straight line is appropriately configured, or a figure in which any one of them is appropriately configured may be presented. For example, regarding the open end 4A and the like and the shape in the vicinity thereof, it may be appropriately devised such as making the tip thinner, using a curve to make the tip smoother, and conversely giving the tip a bulge.

  Further, the shape of the hard band member in the thickness direction may be one provided with appropriate irregularities particularly in the outer surface direction. In addition, even when a design such as a pattern including a color and a texture by selecting a material is applied, all are within the scope of the present invention.

  In addition, since the conventional technology (such as the above-mentioned Patent Document 1) is a flexible band that is wound around the leg, the width of the belt is inevitably wide and the fashionability is also restricted by this. The anti-spreading tool has no functional problem even if each hard band member has a considerably narrow width, and has fewer fashion restrictions. Therefore, there is a high degree of freedom in product development by pursuing fashion.

  As a specific example of the specification of the hard band member, for example, an ABS resin or a polypropylene resin is used, and a basic one having a length of about 25 to 30 cm, a width of about 2 to 2.5 cm, and a thickness of about 0.5 cm is basically used. It is good also as the designed. The examples shown in FIGS. 4 to 6 are of such specifications.

  In addition, the device for preventing leg opening of the present invention is based on the configuration described with reference to the drawings, and includes all other elements added to the scope. For example, on a hard band member made of an appropriate material such as resin, wood, bamboo, metal, or hard rubber, an appropriate kind, an appropriately specified member such as cloth, leather or synthetic leather, It is provided in its entirety, including the surface on the side that contacts the leg, or provided only in part, with buttons, frills and other decorative accessories added, and other widely other elements Anything added with is within the scope of the present invention.

  As described above, the device for preventing spread of legs according to the present invention has proposed a new form as a means for solving the problem of preventing spread of legs when a user sits on a chair, and is particularly portable for women. This is a device that has a high possibility of being able to newly create and expand the market for accessories, and has high industrial applicability.
