Description

  The present invention prevents, for example, thin holes such as towels and handkerchiefs, thick cloths such as banners, flags, tarps, shoes and bags, or holes formed in leather products from breaking. The present invention relates to an invention used to reinforce this hole.

  Conventionally, a number of so-called eyelets or grommets made of metal or rubber have been proposed. A typical example thereof is a grommet that is provided on athletic shoes or the like and reinforces a hole for passing a shoelace. Further, for example, in Patent Document 1 below, a mat fixing tool for reinforcing a mounting hole by preventing a mounting hole for preventing slippage provided in a floor mat or the like of an automobile from collapsing due to use or the like. An invention has been proposed. Thereby, even if it is made of a resin material having a low elastic coefficient such as polypropylene and easily plastically deformed, it is said that a mat fixture having enhanced holding power to the mat can be achieved.

Japanese Patent No. 4493210

  However, the conventional eyelet or grommet needs to be attached to a target location using tools such as a hammer, a hammer, and a hammer. In particular, there is a problem in that it is necessary to prepare a striking rod or a striking plate that matches the size of the eyelet or grommet hole each time it is attached, which increases costs.

  Furthermore, conventional eyelets or grommets are not designed to be reused, as can be understood from their application locations, such as being provided for the purpose of passing shoelaces in athletic shoes and the like. In Patent Document 1 in which a mat fixture is proposed, a description that suggests reuse is not recognized. That is, conventional eyelets or grommets are discarded together with the athletic shoes and mats, even if they are not damaged. Then, for example, a hole is made in a towel, kitchen towel, banner, flag, tarp, etc., and the hole is protected by eyelets or grommets, and is used by being hooked to a convenient place through this hole. In addition, there is a problem that it is not possible to adapt to a use example in which these consumables are replaced when they are damaged, while eyelets or grommets are reused.

  The present invention has been proposed in view of the above circumstances, and holes formed in thin cloth products such as towels and handkerchiefs, thick cloth products such as banners, flags, tarps, cloths such as shoes and bags, or leather products are broken. An object of the present invention is to provide a hole keeper that is used to reinforce this hole, is used to reinforce this hole, does not require a tool for mounting, and can be reused.

  In order to achieve the above object, the present invention forms a substantially dome shape from a flat surface portion having a fitting portion and a dome portion formed by rising from the periphery of the flat surface portion, and the flat surface portion and the dome portion. A female side grommet member having an opening penetrating through the second fitting portion, a second fitting portion having a shape that can be fitted to the fitting portion, and a second plane portion having the same shape as the periphery of the plane portion; A second dome shape formed from the second dome portion raised from the periphery of the second plane portion, a second opening penetrating the second plane portion and the second dome portion, and A male-side grommet member having a cylindrical portion provided at a distal end of a locking portion that is continuously provided on the second flat portion side of the second opening and is inserted into the opening and is locked to an edge of the opening. A hall keeper configured, wherein the fitting portion and the second fitting portion When the cylindrical portion is inserted into the opening with the planar portion and the second planar portion facing each other, the flat portion provided with a hole and having a hole formed therein, The flat part is inserted into the hole while the flat part and the second flat part are facing each other, inserted into the opening, and the locking part is locked to the edge of the opening. The hole can be reinforced by the cylindrical portion while being pressed by the fitting portion and the second fitting portion.

  In particular, in the hall keeper, the connection part between the second opening and the second dome part, the connection part between the second flat part and the cylinder part, and the connection part between the flat part and the opening are rounded. One of the fitting part or the second fitting part is discretely present in a plurality, and the other of the fitting part or the second fitting part is annular. It is preferable.

  The hall keeper according to the present invention is based on the above-described configuration of the female grommet member and the male grommet member so that it has a simple disk-like appearance with a through-hole in use. The product can be used conveniently. For example, a hole is made in a towel, kitchen towel, banner, flag, tarp, etc. as a flat object, and this hole is protected by the through hole of the hole keeper according to the present invention having a simple disk-like appearance. It can be used by hooking to an appropriate place through the inner space. In particular, since the periphery of the flat surface portion and the second flat surface portion have the same shape, the appearance is clean and easy to use and can be used more conveniently. The present invention can be applied to thin cloth products such as towels and kitchen towels, thick cloth products such as banners, flags and tarps, cloths such as shoes and bags, and leather products.

  In addition, while the towel or the like as a flat object is damaged, the hole keeper according to the present invention removes the locking relationship between the female grommet member and the male grommet member by using a predetermined removing tool. Can be reused. When a flat object is sandwiched between the female grommet member and the male grommet member, the fitting part and the second fitting part bite into the flat object, and the flat object can be reliably pressed down. Therefore, the hole keeper according to the present invention is a product that protects and reuses the hole while maintaining a high holding force to a flat object. Furthermore, tools such as a hammer, a hitting bar, and a hitting plate that are necessary for applying conventional eyelets or grommets to athletic shoes and mats are not required. That is, the present invention can provide a hall keeper that anyone can easily attach and detach.

  Particularly, in the hall keeper, the connecting portion between the second opening and the second dome portion, the connecting portion between the second flat portion and the cylindrical portion, and the connecting portion between the flat portion and the opening are rounded. As a result, it is easy to pass the string or the rod into the cylinder of the cylinder part, so that it can be easily hooked at an appropriate place. In addition, the roundness makes it easy to establish a locking relationship between the female grommet member and the male grommet member. With the configuration in which one of the fitting part or the second fitting part is present in a discrete manner and the other of the fitting part or the second fitting part is present in an annular shape, the fitting part and the second fitting part are provided. Since the joint portion bites into a flat object at a plurality of locations, it is possible to more and more achieve pinching with high holding power. By causing one of the fitting part and the second fitting part to exist discretely, it is possible to obtain an effect that it is difficult to cause wrinkles on the flat object when the flat object is sandwiched.

  Hereinafter, some of many embodiments included in the technical scope of the present invention will be described with reference to the drawings. That is, the embodiment described below is only an example of the present invention. The present invention can be variously modified without departing from the matters described in the claims. In addition, in each embodiment, the code | symbol of the same or corresponding location is attached | subjected, and description is abbreviate | omitted.

(First embodiment)
As shown in FIGS. 1 to 6, the hall keeper HK <b> 1 according to the first embodiment is configured by integrating two members including a female side grommet 1 </ b> A and a male side grommet 2 </ b> A through a locking means R. . Then, as shown in FIG. 18, when the female grommet 1A and the male grommet 2A are integrated, a towel T or the like as a flat object in which the hole T1 is formed is attached to the female flat portion 11 and the male flat surface. By sandwiching between the portions 21, the towel T can be held while maintaining a high holding force. Furthermore, by inserting the cylindrical part 23 of the male grommet 2A into the hole T1, the hole T1 can be reinforced by the cylindrical part 23, and the towel T can be prevented from breaking down starting from the hole T1. That is, the hole T1 of the towel T is protected by the through hole H1A of the hole keeper HK1, and can be used by being hooked at an appropriate place through the through hole H1A.

  In addition, as shown in FIG. 37, the hall keeper HK1 according to the present invention has a female grommet 1A and a male grommet 2A that are integrated by applying a punching tool P having a predetermined shape to the locking means R. Can be easily separated. As a result, the hall keeper HK1 can be reused. First, the structure of the female grommet 1A and the male grommet 2A will be described in detail.

  As shown in FIGS. 7 to 11, the female-side grommet 1 </ b> A includes a circular female-side flat surface portion 11 having a recessed recess 111 as a fitting portion, and a female-side dome that rises from the periphery of the female-side flat surface portion 11. It is formed in a substantially dome shape from the portion 12A. Furthermore, it has the female side opening 1a of the circular view planarly penetrated through the female side plane part 11 and the female side dome part 12A. The concave portion 111 exists on the female side flat portion 11 in an annular shape that is radially continuous from the female side opening 1a in the circumferential direction (see, for example, FIG. 8). In addition, regarding a recessed part (fitting part), you may provide more than one with a width | variety in the circumferential direction in the radial direction from the female side opening, and discontinuously. When these recesses are continued, a virtual ring that is concentric with the female opening is formed. Moreover, it is preferable that the width | variety of the circumferential direction which a recessed part has at this time is a width | variety from which the internal angle of the virtual sector formed by the center of a female side opening and a recessed part becomes 30-60 degrees.

  The substantially dome shape of the female side dome portion 12A that rises from the periphery of the female side flat portion 11 is raised toward the female side opening 1a at the center of the female side dome portion 12A of the female grommet 1A, as shown in FIG. It has a mountain shape and its top is located in the vicinity of the female opening 1a. A locked groove 1R, which is an element constituting the locking means R, is formed at the edge on the female side dome 12A side in the female side opening 1a. 1 R of to-be-latched grooves are dented in parallel with the female side plane part 11 toward the inside of the female side dome part 12A from the female side opening 1a, and a locking claw of a locking part (locking piece) described later of the male side grommet 2A. The structure includes a locked side 1R1 to be locked and a slanted side 1R2 whose inner angle formed by the locked side 1R1 is an acute angle, for example, 40 degrees. Since the engaged groove 1R is formed along the edge of the female opening 1a on the female dome 12A side, it has an annular structure when viewed in plan. The connecting portion 1b between the female flat portion 11 and the female opening 1a is chamfered and rounded. This rounding makes it easy to insert the cylindrical portion 23 of the male side grommet 2A into the female side opening 1a, so that the locking means R can be easily formed.

  As shown in FIGS. 12 to 17, the male grommet 2 </ b> A is a circular male flat surface portion 21 having a convex portion 211 as a second fitting portion that protrudes into a shape that can be fitted to the annular concave portion 111. And a male-side dome portion 22A formed so as to rise from the periphery of the male-side flat portion 21, and is formed in a substantially dome shape. Moreover, it has the male side opening 2a of the planar view circular shape which has penetrated the male side plane part 21 and the male side dome part 22A. The substantially dome shape of the male side dome portion 22A that rises from the periphery of the male side flat portion 21 is also a mountain shape that rises toward the male side opening 2a at the center of the male side grommet 1A, like the female side dome portion 12A. The top is located in the vicinity of the male opening 2a.

  Further, a plurality of convex portions 211 are present on the male flat surface portion 21 at radial positions equidistant from the male side opening 2a (five in this embodiment), and are provided discontinuously with a width in the circumferential direction. (See, for example, FIG. 15). If these convex parts 211 are made continuous, a virtual ring concentric with the male side opening 2a is formed. The width in the circumferential direction of the convex portion 211 is such that the inner angle of a virtual sector formed by the center of the male side opening 2a and the convex portion 211 is 30 to 60 degrees (40 degrees in this embodiment). Moreover, you may make a convex part (2nd fitting part) exist in the annular | circular shape which continues in the circumferential direction on the male side plane part at the position of radial distance from the male side opening.

  A cylindrical portion 23 is provided on the male side plane portion 21 side of the male side opening 2a so as to be continuous with the male side opening 2a. The cylindrical portion 23 is provided with a locking portion at the tip thereof, which is inserted into the female side opening 1a and is locked to the locked groove 1R at the edge of the female side opening 1a when integrated with the female side grommet 1A. It has been. The cylinder wall 23 is inclined at an angle of 1 to 5 degrees (2 degrees in the present embodiment) with respect to the cylinder axis in the direction in which the inner diameter becomes narrower toward the tip having the locking portion. With this configuration, a force in a direction away from the locked groove 1R can be applied to the locking portion locked to the locked groove 1R of the female side opening 1a. Therefore, the female side grommet 1A and the male side grommet The locking relationship with 2A can be removed without applying a strong force to facilitate reuse.

  Here, the through hole H1A of the hole keeper HK1 is formed by a structure including the inside of the cylindrical portion 23 of the female side grommet 2A and the male side opening 2a. Therefore, instead of inclining only the cylindrical portion 23 as described above, the inner wall of the through hole H1 of the hole keeper HK is formed from the end of the male opening 2a on the dome portion 12A side to the tip of the cylindrical portion 23. You may make it incline 1-5 degree | times with respect to a cylinder axis | shaft in the direction where an internal diameter becomes narrow toward the front-end | tip of 23.

  Further, in the present invention, regarding the locking relationship established between the locked groove 1R of the female grommet 1A and the locking portion of the male grommet 1A, the removal tool P can be used to remove this. If there is no problem of being too stiff, the configuration in which the cylindrical wall of the cylindrical portion 23 is not inclined in the direction in which the inner diameter becomes narrower toward the tip (the cylindrical wall of the cylindrical portion 23 in the direction in which the inner diameter becomes narrower toward the tip, It may be a hole keeper having a configuration in which the tilt is 0 degree with respect to the cylinder axis. After all, the inner wall of the through hole H1 of the hole keeper HK including the cylindrical portion 23 may be inclined at an angle of 0 to 5 degrees with respect to the cylindrical axis in the direction in which the inner diameter becomes narrower toward the tip having the locking portion. That's fine.

  The locking portion of the cylindrical portion 23 is an element constituting locking means R for integrating the hole keeper HK1 with the locked groove 1R. The locking portion includes 3 to 8, for example, six locking pieces 2R formed by equally dividing the tip of the cylindrical portion 23. A locking claw that locks to the locked groove 1R is formed on the locking piece 2R. The locking claw protrudes outward from the tube portion 23, and has a structure including a claw side 2R1 hooked to the locked side 1R1 and a claw hypotenuse 2R2 whose inner angle formed by the claw side 2R1 is an acute angle, for example, 40 degrees. Prepare. The locking portion forms an annular structure with six locking pieces 2R.

  The connection part 2b between the male side opening 2a and the male side dome part 22A and the connection part 2c between the male side flat part 21 and the cylindrical part 23 are chamfered and rounded. The connecting part 2c between the male side flat part 21 and the cylindrical part 23 is rounded, so that it corresponds to the connecting part 1b between the female side flat part 11 and the female side opening 1a, and the cylindrical part 23 is inserted into the female side opening 1a. The locking means R can be easily constructed as a structure that is easy to do. The connecting portion 2b between the male opening 2a and the male dome portion 22A is rounded, so that it is possible to easily pass a string or a rod into the cylinder portion 23 (in the through hole H1A of the hole keeper HK1). The hole keeper HK1 can be easily hooked to an appropriate place.

  As shown in FIGS. 1 to 6, the hall keeper HK1 is configured by integrating a female grommet 1A and a male grommet 2A. Specifically, while the female side flat part 11 and the male side flat part 21 are made to face each other, the cylindrical part 23 of the male grommet 2A is inserted into the female side opening 1a, and the tip of the cylindrical part 23 is locked. The locking means R is configured by engaging the portion (locking piece 2R) with the locked groove 1R on the edge on the female dome 12A side, and these are integrated. At this time, the concave portion 111 of the female side grommet 1A and the convex portion 211 of the male side grommet 2A are positioned so as to be fitted.

  As shown in FIG. 18, when the hole keeper HK1 is used, when the female grommet 1A and the male grommet 2A are integrated, the cylindrical portion 23 is inserted into the hole T1 formed in the towel T, and The towel T is sandwiched between the female side plane part 11 and the male side plane part 21. Thereby, the hole T1 can be reinforced by the cylindrical portion 23 while the concave portion 111 and the convex portion 211 are bitten into the towel T and pressed. Further, if the through hole H1A (inside the cylindrical portion 23 and the male side opening 2a) of the hall keeper HK1 sandwiching the towel T is hooked on an appropriate place, for example, a hook provided in a washroom, the towel T Can be used for wiping off. The hole T1 formed in the towel T is protected by the through hole H1A (cylinder portion 23) and does not break. Further, the linear length of the cylindrical portion 23 or the position of the locking means R constituted by the locking portion (locking piece 2R) of the cylindrical portion 23 and the locked groove 1R at the edge on the female side dome portion 12A side. By finely adjusting the distance, the distance between the female side plane part 11 and the male side plane part 21 can be adjusted. If the distance where the female side plane part 11 and the male side plane part 21 face each other is increased, a thicker flat object can be sandwiched. If the distance where the female side plane part 11 and the male side plane part 21 face each other is narrowed, even a thin flat object can be securely bited and pinched.

  Furthermore, as shown in FIG. 37, the hole keeper HK1 can be reused by removing the locking relationship between the female grommet 1A and the male grommet 2A by the punch P that acts on the locking means R. This punching tool P includes a punching cylinder part P1 corresponding to the diameter of the locking part of the cylinder part 23 and having a diameter substantially the same as this diameter. The hollow cylinder portion P1 has a structure in which a cylinder outer wall P11 protrudes from the cylinder inner wall P12 at the tip on the side that acts on the locking means R. In addition, if the diameter of the cylinder outer wall P11 is made to coincide with the diameter of a virtual ring formed by connecting the outermost diameter parts of the six locking pieces 2R, the female cylinder grommet 1A and The locking relationship with the male grommet 2A can be removed with minimal stress.

  With such a structure of the punching tool P, when the punching cylinder part P1 is made to act on the locking means R, the locking claw of the locking part (locking piece 2R) is bent to the inside of the cylinder part 23 with little stress. Therefore, the locking relationship between the female grommet 1A and the male grommet 2A can be easily removed.

  That is, the locking part (locking piece 2R) at the tip of the cylindrical part 23 of the male grommet 2B is inserted into the female opening 1a while the female flat part 11 and the male flat part 21 face each other. Then, the female grommet 1B and the male grommet 2B can be integrated by engaging with the engaged groove 1R on the edge on the female dome portion 12B side. Then, as shown in FIG. 36, when the female grommet 1B and the male grommet 2B are integrated, the towel T is sandwiched between the female flat surface portion 11 and the male flat surface portion 21, By inserting the cylindrical portion 23 into the formed hole T1, the cylindrical portion 23 can reinforce the hole T1 while the concave portion 111 and the convex portion 211 are bitten into the towel T and pressed. In addition, by removing the locking relationship between the female grommet 1B and the male grommet 2B with the removal tool P that acts on the locking means R as shown in FIG. 37, the hall keeper HK2 according to the second embodiment is also re-activated. Can be used.

  As shown in FIG. 19 and the like, the female-side dome portion 12B rises from the periphery of the female-side flat surface portion 11 and includes a flat portion on the top and a female-side opening 1a located at the central portion of the female-side grommet 1B. It has a plateau shape with a flat portion 12b. The male dome portion 22B also swells from the periphery of the male flat surface portion 21, and is a plateau provided with a male flat portion 22b that includes a flat portion on the top and a male opening 2a located at the center of the male grommet 2B. It has a mold shape. However, it is not necessary for the male dome portion 22B and the female dome portion 12B to have the same plateau shape.

  Therefore, in the present invention, it is convenient in various life scenes as a hole keeper that has a simple disk-like appearance with a through-hole in use based on the configuration of the female grommet member and the male grommet member as described above. It can be used for. For example, a hole is made in a towel, the hole is protected by a through hole of the hole keeper, and the fitting portion of the female grommet member and the second fitting portion of the male grommet member are bitten into the towel so that the towel is securely sandwiched. Can be worn. If a towel is pinched, it can be used by being hooked to an appropriate place through the space in the hole of the hole keeper. In particular, the configuration of the female side plane portion and the male side plane portion having the same shape, the appearance is clean and aesthetic, and is easy to use. Also, tools such as hammers, hammers, and dishes are not required for these operations. And, if the towel with a hole has been damaged due to secular change, etc., it is exchanged, while the hole keeper according to the present invention uses a predetermined removal tool, so that the female grommet member and the male grommet member Since the locking relationship can be removed, it can be easily reused.

  As mentioned above, although embodiment which illustrated the hall keeper which concerns on this invention has been demonstrated, this invention is not limited to the said embodiment, Unless it deviates from the matter described in the claim, Various design changes can be made. For example, in the above-described embodiment, the female-side grommet fitting portion has a concave shape, and the male-side grommet second fitting portion has a convex shape.
