Description

Technical Field

[0001] This utility model relates to a fastener for lower garments. Background Technology

[0002] In the past, most people would wear a belt when wearing jeans or other bottoms. The purpose of a belt is to tighten the waist of the bottoms and prevent them from slipping down. Of course, belts have buckles, which are fastened to specific positions on the belt to tighten the waist of the bottoms.

[0003] However, belts tend to stretch over time, leading to an unsightly appearance. Additionally, since the color of the belt plays a crucial role in the overall outfit, there's a need to own belts in multiple colors.

[0004] Furthermore, the use of belt buckles as a fashion accessory has increased significantly. Consequently, many users now own multiple belts with various types of buckles. However, using multiple belts in this way can also create a financial burden.

[0005] However, what is needed is the ability to use only beltless buckles on the bottoms and to use a variety of buckles.

[0011] In this invention, the decorative panel can be freely replaced in the fasteners for lower garments.

[0012] In this invention, the decorative panel constituting the fastener for lower garments is more firmly fixed to the first fastener.

[0013] Solution for solving the problem

[0014] The fastener for lower garments according to the present invention, used to achieve the above-mentioned objectives, is a fastener for connecting one side of a lower garment to the other side of a lower garment for adjusting the waist size of the lower garment. It may include: a first fastener, comprising a first outer fastener plate disposed on the outer front side of the lower garment side and a first inner fastener plate coupled to the first outer fastener plate and having a hooking protrusion protruding toward the other side of the lower garment; a second fastener, comprising a second outer fastener plate disposed on the outer front side of the other side of the lower garment and a second inner fastener plate coupled to the second outer fastener plate, wherein the second inner fastener plate and the second outer fastener plate have a pair of through holes and fixing holes for hooking the hooking protrusion through; and a decorative panel, which is detachably mounted on the first outer fastener plate.

[0015] A hooking groove is formed on the back of the aforementioned decorative panel for inserting the aforementioned first outer fixing piece. The hooking groove is also open to one side edge of the aforementioned decorative panel, and a hooking slit can be formed at the edge of the hooking groove for hooking the edge of the aforementioned first outer fixing piece.

[0016] Multiple friction protrusions that are closely attached to the inner surface of the hook slit may be formed in a row on the back edge of the first outer fixing piece.

[0017] A spacer end is formed protruding from the back of the first outer fixing piece, and a first mounting protrusion can be formed protruding from the spacer end, penetrating the mounting hole formed in the first inner fixing piece.

[0018] The aforementioned hook-on protrusion may include: a protrusion body integral with the aforementioned first inner fixing piece and a protrusion head disposed at the front end of the aforementioned protrusion body and having a diameter larger than that of the aforementioned protrusion body.

[0019] The diameter of the protruding head is equal to or less than the inner diameter of the protruding through hole, and the inner diameter or width of the protruding fixing hole can be greater than the diameter of the protruding body and less than the diameter of the protruding head.

[0020] On the opposing surfaces of the second outer fixing piece and the second inner fixing piece, a second mounting protrusion for engaging the second outer fixing piece and the second inner fixing piece, a guide rail and a guide protrusion for guiding the second mounting protrusion, and a pressing groove for pressing the second mounting protrusion in are formed.

[0056] The following detailed description of some embodiments of the present invention is provided with reference to schematic diagrams. It should be noted that when affixing reference numerals to structural elements in the accompanying drawings, the same reference numerals should be used as much as possible for the same structural elements, even if they are labeled in different drawings. Furthermore, in describing embodiments of the present invention, detailed descriptions of related well-known structures or functions will be omitted if it is believed that such detailed descriptions would hinder understanding of the embodiments of the present invention.

[0057] Furthermore, when describing the structural elements of embodiments of this utility model, terms such as first, second, A, B, (a), and (b) may be used. These terms are merely for distinguishing the structural element from other structural elements, and the nature, order, or sequence of the corresponding structural elements are not limited by these terms. When referring to a structural element as being "connected," "combined," or "in contact" with other structural elements, it may mean that the aforementioned structural element is directly connected or in contact with other structural elements. It should also be understood that each structural element may have other structural elements "connected," "combined," or "in contact" with it.

[0058] The preferred embodiment of the fastener for lower garments according to the present invention will be described with reference to the accompanying drawings. The fastener for lower garments of the present invention can be used with various types of lower garments. For example, it can be applied to all lower garments that require adjustable waist size, such as trousers and skirts. The fastener for lower garments of the present invention is most suitable for denim-style lower garments.

[0059] The fastener for lower garments of this utility model can be installed on the zipper flap (fly) and its corresponding part of the lower garment. In this specification, the side where the zipper flap is located is... Figures 1 to 3 The side of the zipper flap is designated as 1'. The opposite side is designated as 1'. Typically, the vertical opening in the center of the trousers, partially covered by the zipper flap, is connected to the other side by a zipper and / or buttons.

[0060] In the lower garment to which this utility model is applied, a first fastener 10, which will be described below, is installed on one side 1 of the lower garment. Multiple through holes (not shown in the drawings) may be formed on the aforementioned side 1 of the lower garment. These through holes do not necessarily need to be formed before the installation of the first fastener 10; they may be formed during the installation of the first fastener 10.

[0061] A through hole 3 may be formed on the other side 1' of the aforementioned lower garment. There may be more than one through hole 3. The shape of the through hole 3 may be the same as the combined shape of the protruding through holes 212, 222 and protruding fixing holes 213, 223 formed in the second fastener 20, which will be described below.

[0062] A first fastener 10 is installed on one side 1 of the aforementioned lower garment, and a second fastener 20 is installed on the other side 1' of the aforementioned lower garment.

[0063] The aforementioned first fastener 10 may include a first outer fastening piece 110 and a first inner fastening piece 120. The first outer fastening piece 110 is located on the outer front of the lower garment side 1, and the first inner fastening piece 120 is located on the outer back of the lower garment side 1, thereby achieving mutual engagement. For reference, the first inner fastening piece 120 is not necessarily located on the outer back of the lower garment side 1. That is, the first inner fastening piece 120 may be located inside the lower garment side 1, with the hook protrusion 124 protruding through the lower garment side 1 toward the other side 1' of the lower garment.

[0064] The first outer fixing piece 110 has a plurality of first mounting protrusions 112 for engaging with the first inner fixing piece 120. In the illustrated embodiment, four first mounting protrusions 112 are provided. The number of first mounting protrusions 112 is sufficient as long as it is the number required for engaging the first outer fixing piece 110 with the first inner fixing piece 120. In this embodiment, the first outer fixing piece 110 is quadrilateral, therefore four first mounting protrusions 112 are used. That is, each first mounting protrusion 112 is positioned corresponding to a corner of the first outer fixing piece 110. The first mounting protrusions 112 protrude from the surface of the first outer fixing piece 110 that contacts the side 1 of the lower garment.

[0065] A plurality of friction protrusions 114 may be disposed on the surface of the first outer fixing piece 110 where the first mounting protrusion 112 is formed. The friction protrusions 114 may be in close contact with the inner surface of the hanging slit 33 formed in the decorative panel 30, which will be described below, to generate friction. The friction protrusions 114 are arranged in a row along the edge of one side surface of the first outer fixing piece 110.

[0066] A spacer end 116 protrudes from the surface of the first outer fixing piece 110 that contacts the lower garment side 1. The spacer end 116 is quadrilateral in shape. The first mounting protrusion 112 is located adjacent to the four corners of the spacer end 116. The spacer end 116 is formed at a position corresponding to the hanging groove 32 of the decorative panel 30, which will be described below. The surface of the spacer end 116, i.e., the surface where the first mounting protrusion 112 is formed, is aligned with the edge surface of the hanging groove 32 of the decorative panel 30, which will be described below. That is, the spacer end 116 is located inside the hanging groove 32.

[0067] The first inner fixing piece 120 is combined with the first outer fixing piece 110 and is located on the inner surface of the lower garment side 1. That is, the first outer fixing piece 110 is located on the outer surface of the lower garment side 1, and the first inner fixing piece 120 is located on the inner surface of the lower garment side 1, thereby being fastened by the first mounting protrusion 112. For this purpose, a mounting hole 122 is formed in the first inner fixing piece 120. The mounting hole 122 is a portion through which the first mounting protrusion 112 passes. Therefore, the mounting hole 122 is located at a position corresponding to the position of the first mounting protrusion 112. The first mounting protrusion 112 that passes through the lower garment side 1 passes through the mounting hole 122. If the free end of the first mounting protrusion 112 that passes through the mounting hole 122 is struck, so that it has an outer diameter larger than the inner diameter of the mounting hole 122, the first outer fixing piece 110 and the first inner fixing piece 120 can be combined in such a way that the lower garment side 1 is positioned in the middle.

[0068] The aforementioned first inner fixing piece 120 may have a hook-on protrusion 124. The hook-on protrusion 124 can adjust the waist size of the lower garment. The hook-on protrusion 124 protrudes from the rear of the aforementioned first inner fixing piece 120.

[0069] The aforementioned hook-up protrusion 124 allows for adjustment of the waist size. The hook-up protrusion 124 includes a protruding body 125 with a predetermined outer diameter and a protruding head 126 formed at the end of the protruding body 125 with an outer diameter larger than that of the protruding body 125. The protruding body 125 may be cylindrical. The protruding head 126 may have a generally hemispherical shape. When viewed from the rear side of the first inner fixing piece 120, the protruding head 126 may be circular with a predetermined outer diameter. This outer diameter is formed to be larger than the outer diameter of the protruding body 125. The hook-up protrusion 124 may be located at the geometric center of the first inner fixing piece 120.

[0070] The second fastener 20 may include a second outer fastener 210 and a second inner fastener 220. The second outer fastener 210 is located on the outer front of the other side 1' of the lower garment, and the second inner fastener 220 is located on the outer back of the other side 1' of the lower garment, thereby achieving mutual engagement. Of course, the second inner fastener 220 may also be located inside the other side 1' of the lower garment. In this case, the through hole 3 does not need to penetrate the other side 1' of the lower garment.

[0071] In this embodiment, the second outer fixing piece 210 is in the shape of an elliptical plate. However, the shape of the second outer fixing piece 210 can be any shape, as long as it is plate-shaped. Of course, the corners of the second outer fixing piece 210 are preferably formed as curves.

[0072] The second outer fixing piece 210 may be provided with a plurality of paired through holes 212 and fixing holes 213. The through holes 212 may be formed as circles with a relatively large inner diameter. The fixing holes 213 may be formed as circles with a relatively small inner diameter. Furthermore, the through holes 212 and fixing holes 213 are connected. The inner diameter of the through holes 212 may be equal to or slightly larger than the diameter of the protruding head 126 of the hook protrusion 124. That is, the dimensions are designed so that the protruding head 126 can easily pass through the through holes 212.

[0073] The inner diameter or vertical width (based on the attached drawings) of the aforementioned protrusion fixing hole 213 is smaller than the outer diameter of the aforementioned protrusion head 126, but larger than the outer diameter of the aforementioned protrusion body 125. Therefore, when the aforementioned hook protrusion 124 is located in the position of the protrusion fixing hole 213, the protrusion head 126 of the aforementioned hook protrusion 124 will not fall off from the aforementioned protrusion fixing hole 213.

[0074] The second outer fixing piece 210 is provided with a protruding grille 214 surrounding the pair of protruding through holes 212 and protruding fixing holes 213. The protruding grille 214 can be closely attached to the outer front of the other side 1' of the lower garment. The protruding grille 214 can be formed into an elliptical shape that is relatively larger than the guide grille 225 described below.

[0075] A plurality of second mounting protrusions 215 are disposed on the second outer fixing piece 210. The second mounting protrusions 215 can be formed on the protruding fence 214. The second mounting protrusions 215 can protrude from the upper end of the protruding fence 214. The second mounting protrusions 215 are used to engage with the second inner fixing piece 220. Unlike the first mounting protrusion 112, which is formed in a rod shape, the second mounting protrusions 215 are formed in a plate-like serrated shape. The second mounting protrusions 215 are generally trapezoidal plates. The width of the second mounting protrusions 215 decreases towards the front end, thereby easily penetrating the other side 1' of the lower garment. A plurality of the second mounting protrusions 215 can be formed in a row on the protruding fence 214. Therefore, in this embodiment, the shape of the second mounting protrusions 215 is elliptical.

[0076] Friction protrusions 217 are formed protruding from the back edge of the second outer fixing piece 210. These friction protrusions 217 may have the same structure as the friction protrusions 114 of the first outer fixing piece 110. In this embodiment, they are formed in a cuboid shape. Multiple friction protrusions 217 are arranged in a row. These friction protrusions 217 serve to securely fix the second outer fixing piece 210, more precisely, the second fixing member 20, to the other side 1' of the lower garment.

[0077] The second inner fixing piece 220 is a plate with the same shape as the second outer fixing piece 210. In this embodiment, the second inner fixing piece 220 is an elliptical plate. Multiple pairs of protruding through holes 222 and protruding fixing holes 223 are also formed on the second inner fixing piece 220. In this embodiment, two pairs of protruding through holes 222 and protruding fixing holes 223 are arranged adjacent to each other. The protruding through holes 222 and protruding fixing holes 223 are formed to have the same shape and number as the pairs of protruding through holes 212 and protruding fixing holes 213 formed on the second outer fixing piece 210.

[0078] from Figure 10As can be seen, a structure for engaging with the second outer fixing piece 210 is disposed on one side surface of the second inner fixing piece 220. A guide rail 225 is disposed around the paired protruding through holes 222 and protruding fixing holes 223. The guide rail 225 protrudes a predetermined distance from the surface of the second inner fixing piece 220. The guide rail 225 guides the position of the second mounting protrusion 215 when the second outer fixing piece 210 engages with the second inner fixing piece 220. That is, it prevents the second mounting protrusion 215 from deforming towards the protruding through holes 222 and protruding fixing holes 223. The upper portion of the guide rail 225 is formed as a curved surface. The second mounting protrusion 215 can be guided so that one side surface is in close contact with the outer surface of the guide rail 225.

[0079] A guide protrusion 227 is formed on the outer side of the guide fence 225, corresponding to the position of the second mounting protrusion 215. Unlike the guide fence 225, the guide protrusion 227 does not protrude, but rather protrudes from the surface of the second inner fixing piece 220. The outer surface of the guide protrusion 227 is curved. This is for the same reason that the upper portion of the guide fence 225 is curved, in order to guide the second mounting protrusion 215 into the pressing groove 229.

[0080] A pressing groove 229 is formed between the guide rail 225 and the guide protrusion 227. The pressing groove 229 is the portion that is pressed into the second mounting protrusion 215 by deformation. The second outer fixing piece 210 and the second inner fixing piece 220 can be engaged with each other by pressing in the second mounting protrusion 215.

[0081] For reference, the structures of the second outer fixing piece 210 and the second inner fixing piece 220 can be opposite. That is, the structures for engaging the second outer fixing piece 210 and the second inner fixing piece 220 can be formed in opposite ways. In other words, the second mounting protrusion 215 can be located on the second inner fixing piece 220, and the guide rail 225, guide protrusion 227, and press-in groove 229 can be located on the second outer fixing piece 210. The friction protrusion 217 can also be located on the second inner fixing piece 220. Alternatively, the friction protrusion 217 can be located on both the second outer fixing piece 210 and the second inner fixing piece 220 simultaneously.

[0082] A decorative panel 30 can be installed on the first outer fixing piece 110 of the first fastener 10. A predetermined pattern can be formed on the front of the decorative panel 30. The pattern can be varied to meet the different preferences of the user wearing the bottom garment. That is, the decorative panel 30 is replaceable. The user can install a decorative panel 30 with a desired pattern on the first outer fixing piece 110 of the first fastener 10 as needed.

[0083] Therefore, a mounting groove 32 is formed on the back of the aforementioned decorative panel 30. The aforementioned first outer fixing piece 110 is located within the mounting groove 32. From Figure 3 As can be seen from the image, the mounting groove 32 is formed with an opening on one side edge on the back of the decorative panel 30. This is to allow the first outer fixing piece 110 to be inserted into the interior of the mounting groove 32 through the open edge.

[0084] A mounting slit 33 is formed along the bottom edge of the mounting groove 32. The edge of the first outer fixing piece 110 is inserted into the mounting slit 33. The edge of the first outer fixing piece 110 is pressed into the mounting slit 33. The friction protrusion 114 makes it easier and more forceful for the edge of the first outer fixing piece 110 to be inserted into the mounting slit 33.

[0085] On the other hand, the leaf spring 35 can be located between the decorative panel 30 and the first outer fixing piece 110, making their connection more secure. The leaf spring 35 is a leaf spring formed with a curved surface having a specified curvature. Therefore, when the leaf spring 35 is located between the decorative panel 30 and the first outer fixing piece 110, it is in a state of elastic deformation in a flat plate shape to provide a restoring force, thereby making the decorative panel 30 and the first outer fixing piece 110 more securely connected.

[0086] Figure 12 and Figure 13 Other examples of the second fastener 20 described above are shown. That is... Figure 12 Other examples of the second outer fixing piece 210' are shown in the figure. Figure 13 Other examples of the second inner fixing piece 220' are shown in the figure.

[0087] The aforementioned second outer fixing piece 210' is in the shape of an elliptical plate. However, the shape of the aforementioned second outer fixing piece 210' can be any shape, as long as it is plate-shaped. Of course, the corners of the second outer fixing piece 210' are preferably formed as curves.

[0088] The second outer fixing piece 210' may be provided with a plurality of paired through holes 212' and fixing holes 213'. The through holes 212' may be formed as circles with a relatively large inner diameter. The fixing holes 213' may be formed as circles with a relatively small inner diameter. Furthermore, the through holes 212' and fixing holes 213' are connected. The inner diameter of the through holes 212' may be equal to or slightly larger than the diameter of the protruding head 126 of the hook protrusion 124. That is, the dimensions are designed so that the protruding head 126 can easily pass through the through holes 212'.

[0089] The inner diameter or vertical width (based on the attached drawings) of the aforementioned protrusion fixing hole 213' is smaller than the outer diameter of the aforementioned protrusion head 126, but larger than the outer diameter of the aforementioned protrusion body 125. Therefore, when the aforementioned hook protrusion 124 is located in the position of the protrusion fixing hole 213', the protrusion head 126 of the aforementioned hook protrusion 124 will not fall off from the aforementioned protrusion fixing hole 213'.

[0090] The second outer fixing piece 210' is provided with a protruding grille 214' surrounding the pair of protruding through holes 212' and protruding fixing holes 213'. The protruding grille 214' can be closely attached to the outer front of the other side 1' of the lower garment. The protruding grille 214' can be formed in a shape that is relatively larger than the guide grille 225' which will be described below. In this embodiment, two protruding grilles 214' are provided. That is, the protruding grilles 214' are respectively arranged around the pair of protruding through holes 212' and protruding fixing holes 213'.

[0091] The second outer fixing piece 210' is provided with a plurality of second mounting protrusions 215'. The second mounting protrusions 215' can be formed on the protruding fence 214'. The second mounting protrusions 215' can protrude from the upper end of the protruding fence 214'. The second mounting protrusions 215' are used to engage with the second inner fixing piece 220'. The second mounting protrusions 215' are formed in a plate-like serrated shape. The second mounting protrusions 215' are generally trapezoidal plate-shaped. The second mounting protrusions 215' are formed such that their width decreases towards the front end, thereby easily penetrating the other side 1' of the lower garment. A plurality of the second mounting protrusions 215' can be formed on the protruding fence 214'. The shape of the second mounting protrusions 215' can be the same as the shape of the protruding fence 214'.

[0092] Friction protrusions 217' are formed protruding from the back edge of the second outer fixing piece 210'. These friction protrusions 217' may have the same structure as the friction protrusions 114 of the first outer fixing piece 110. In this embodiment, they are formed in a cuboid shape. Multiple friction protrusions 217' are arranged in a row. These friction protrusions 217' serve to securely fix the second outer fixing piece 210' to the other side 1' of the lower garment.

[0093] The second inner fixing piece 220' is a plate with the same shape as the second outer fixing piece 210'. In this embodiment, the second inner fixing piece 220' is an elliptical plate. The second inner fixing piece 220' also has a plurality of paired protruding through holes 222' and protruding fixing holes 223'. In this embodiment, two pairs of protruding through holes 222' and protruding fixing holes 223' are arranged adjacent to each other. The protruding through holes 222' and protruding fixing holes 223' are formed to have the same shape and number as the paired protruding through holes 212' and protruding fixing holes 213' formed on the second outer fixing piece 210'.

[0094] from Figure 13 As can be seen, a structure for engaging with the second outer fixing piece 210' is provided on one side surface of the second inner fixing piece 220'. A guide rail 225' is arranged around the paired protruding through holes 222' and protruding fixing holes 223'. The guide rail 225' protrudes a predetermined distance from the surface of the second inner fixing piece 220'. When the second outer fixing piece 210' engages with the second inner fixing piece 220', the guide rail 225' serves to ensure that one side surface of the second mounting protrusion 215' is in close contact with and guides the position of the second mounting protrusion 215'. That is, it prevents the second mounting protrusion 215' from deforming towards the protruding through holes 222' and protruding fixing holes 223'. The upper portion of the guide rail 225' is formed as a curved surface. The second mounting protrusion 215' can be guided to a state where one side surface is in close contact with the outer surface of the guide rail 225'. In this embodiment, there are two guide fences 225', which is the same as the number of pairs of protruding through holes 222' and protruding fixing holes 223'.

[0095] A guide protrusion 227' is formed on the outer side of the guide fence 225', corresponding to the position of the second mounting protrusion 215'. The guide protrusion 227' does not protrude like the guide fence 225', but rather protrudes from the surface of the second inner fixing piece 220'. The outer surface of the guide protrusion 227' is curved. This is for the same reason that the upper portion of the guide fence 225' is curved, in order to guide the second mounting protrusion 215' into the pressing groove 229'.

[0096] A pressing groove 229' is formed between the guide rail 225' and the guide protrusion 227'. The pressing groove 229' is the portion that is pressed into the second mounting protrusion 215' by deformation. The second outer fixing piece 210' and the second inner fixing piece 220' can be engaged with each other by pressing in the second mounting protrusion 215'.

[0097] Furthermore, as described above, the structures of the second outer fixing piece 210' and the second inner fixing piece 220' can be opposite. That is, the structures for engaging the second outer fixing piece 210' and the second inner fixing piece 220' can be formed in opposite directions. In other words, the protruding fence 214' and the second mounting protrusion 215' can be located on the second inner fixing piece 220', and the guide fence 225', the guide protrusion 227', and the pressing groove 229' can be located on the second outer fixing piece 210'. The friction protrusion 217' can also be located on the second inner fixing piece 220'. Alternatively, the friction protrusion 217' can be located on both the second outer fixing piece 210' and the second inner fixing piece 220' simultaneously.

[0098] The following is a detailed description of the use of the buckle for lower garments of this utility model, which has the structure described above, when installed on lower garments.

[0099] The first fastener 10 is fixedly disposed on one side 1 of the lower garment. Specifically, the first outer fastener 110 is positioned on the outer front of one side of the lower garment 1, and the first inner fastener 120 is positioned on the outer back of one side of the lower garment 1. The first mounting protrusion 112 of the first outer fastener 110 passes through the mounting hole 122 of both one side of the lower garment 1 and the first inner fastener 120. Furthermore, by striking the front of the first mounting protrusion 112, the outer diameter of the front of the first mounting protrusion 112 is made larger than the mounting hole 122. At this time, the length of the first mounting protrusion 112 is shorter than its original length, and the first outer fastener 110 and the first inner fastener 120 are joined together with the lower garment 1 positioned in the middle. At this time, the first outer fastener 110 is tightly fixed to the outer front of one side of the lower garment 1, and the first inner fastener 120 is tightly fixed to the outer back of one side of the lower garment 1.

[0100] Then, the second fastener 20 is fixedly disposed on the other side 1' of the lower garment. The second outer fastener 210 is positioned on the outer front of the other side 1' of the lower garment, and the second inner fastener 220 is positioned on the outer back of the other side 1' of the lower garment. In this state, the second outer fastener 210 and the second inner fastener 220 are tightly joined together with the other side 1' of the lower garment positioned in the middle.

[0101] When the second outer fixing piece 210 and the second inner fixing piece 220 are tightly attached to the other side 1' of the garment, the second mounting protrusion 215 of the second outer fixing piece 210 penetrates the other side 1' of the garment and is pressed into the pressing groove 229 of the second inner fixing piece 220. That is, the front end of the second mounting protrusion 215 is pressed into the pressing groove 229 in a deformed state. At this time, the guide rail 225 and the guide protrusion 227 serve to guide the front end of the second mounting protrusion 215 into the pressing groove 229.

[0102] exist Figure 4 and Figure 5 As can be seen, the first fastener 10 and the second fastener 20 are fixed to one side 1 and the other side 1' of the lower garment. That is, for the lower garment fastener of this utility model installed on the lower garment in the state described above, the user can adjust the waist size and fix it by combining the first fastener 10 and the second fastener 20 when wearing the lower garment.

[0103] When the fastener for lower garments of this utility model is installed on the lower garment, the hook-up protrusion 124 of the first fastener 10 protrudes to the other side 1' of the lower garment, thereby passing through one of the protrusion through holes 212 and 222 of the second fastener 20. That is, the hook-up protrusion 124 passes through the specific protrusion through hole 212 and 222 selected according to the user's waist size. When the hook-up protrusion 124 moves to the protrusion fixing hole 213 and 223 connected to the protrusion through hole 212 and 222, the first fastener 10 and the second fastener 20 are engaged. Figure 6 The diagram shows the state in which the aforementioned hook protrusion 124 is located in the aforementioned protrusion fixing holes 213 and 223 and is engaged with the first fixing member 10 and the second fixing member 20.

[0104] On the other hand, the aforementioned decorative panel 30 can be detached from the first outer fixing piece 110 of the first fixing member 10. Therefore, the user can replace the aforementioned decorative panel 30 as needed. This is to allow the user to replace the decorative panel 30 with one of different shapes or front patterns. Figure 11 A decorative panel 30' with a shape that extends long to the left and right is shown.

[0105] Although not shown in the figures, the decorative panels 30 and 30' described above can be various shapes such as circular, elliptical, or hemispherical, rather than quadrilateral, and the patterns on their outer surfaces can also be diverse. Therefore, users can choose decorative panels 30 and 30' with desired shapes or patterns for installation.

[0106] On the other hand, when the decorative panels 30 and 30' are combined with the first fixing member 10, if a leaf spring 35 is placed between the inner surface of the hanging groove 32 of the decorative panel 30 and the first outer fixing piece 110 of the first fixing member 10, the combination of the first outer fixing piece 110 of the first fixing member 10 and the decorative panels 30 and 30' can be made more secure.

[0107] When using Figure 12 and Figure 13 When the second fastener 20 is shown, the other side 1' of the lower garment around the through hole 3 can be held more securely. This is because the protruding grille 214' and guide grille 225' formed on the second outer fastener 210' and the second inner fastener 220' can firmly reinforce the other side 1' of the lower garment around the through hole 3.
