Description

[Technical field]

[0001] The present invention relates to a holder used when installing a flexible net in a desired position, and more specifically, to a net holder that holds the net while reducing damage to the mesh of the net, and allows the net to be installed efficiently and easily even if the net does not have grommets or the dimensions of the grommet positions do not match. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been a wide range of demands for nets having a mesh formed by weaving or tying together threads or strings in a lattice pattern, and they have been widely used, for example, as animal protection nets, bird protection nets, wind protection nets, and shading nets. These nets are installed in the desired position using grommets that are pre-installed at the corners or edges of the nets. In other words, the nets are installed in the desired position by passing fixing members such as string, wire, or cable ties through the grommets and tying them to posts or the like.

[0003] Some nets do not have eyelets pre-installed. In such cases, the net is installed by passing a string through the mesh directly, or by attaching commercially available eyelets. Furthermore, the dimensions of the net often do not fit the area where it is desired to install it. In other words, the net may be too big (too long) or too small (too short) and cannot be installed efficiently or properly. In such cases, the net is installed by threading a string directly through the meshes in the middle of the net, or by braiding the net together with string or thread to make a long net to fit the dimensions.

[0004] However, when pressure (load) is applied to the net by wind, animals, birds, etc., stress is concentrated in the eyelets and mesh parts through which the strings and other fixing members are passed, and the net may break and be damaged. In such cases, it is common to repair the damaged area by weaving the net with a different string or thread, or by overlapping and pasting a smaller net on top of the damaged net, just as in the case of joining nets together. However, joining the nets together and repairing damaged sections is a time-consuming and tedious task.

[0005] Meanwhile, a fastener with a string has been proposed that clamps the corners of the net to set the net in a desired position (see, for example, Patent Document 1). Also, a fastener has been proposed which is not a net but a sheet fastener, but has a convex portion and a concave portion formed in the portion that holds the sheet and which can interlock with each other to prevent the sheet from slipping or coming off (see, for example, Patent Document 2).

[0006] The above-mentioned fasteners with strings and sheet fasteners can efficiently install a net even if the net does not have grommets. However, they cannot hold the net in a way that prevents it from being damaged. They also cannot join the nets together or repair damaged areas. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Registered Utility Model No. 3236205 [Patent Document 2] Registered Utility Model No. 3041825 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention was developed in consideration of the above-mentioned conventional circumstances, and aims to provide a net holder that can hold the net while preventing it from being damaged, and that can also be used to connect nets together and repair damaged areas. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the net holder of the present invention is characterized in that it comprises a first clamping portion arranged along one side of the net, a second clamping portion arranged along the other side of the net, an opening that penetrates the first clamping portion and the second clamping portion while they are arranged opposite each other, and an engagement means that connects the opposing first clamping portion and second clamping portion to clamp the net.

[0010] In other words, the net holder of the present invention does not hold the net in such a way that stress is concentrated on certain meshes, but holds the net in a planar manner with a first clamping part and a second clamping part arranged opposite each other through the net (sandwiched between them), dispersing the stress on the net. Therefore, when installing the net, there is no need to provide grommets in advance, and the installation position of the net holder is not limited to the corners or periphery of the net, and can be freely performed.

[0011] In the above net holder, the engaging means may be capable of being released after engagement. In this case, it is preferable that the engaging means is capable of adjusting the joining position in multiple stages in the spacing direction between the first clamping portion and the second clamping portion which clamp the net. In the above net holder, the engagement means may be provided at a plurality of locations.

[0012] In the above net holder, the first clamping portion and the second clamping portion may be connected to each other. Furthermore, in the above-mentioned net holder, the first clamping portion and the second clamping portion may be separate from each other.

[0013] The net holder may further include a fitting means for clamping the net in a partially biased manner toward one side or the other side. In this case, it is preferable that the fitting means is provided in a ring shape.

[0014] A specific example of a net holder of the present invention includes a first clamping portion arranged along one side of the net, a second clamping portion arranged along the other side of the net, an opening that penetrates while the first clamping portion and the second clamping portion are arranged opposite each other, an engagement means that connects the opposing first clamping portion and second clamping portion to clamp the net, and a fitting means that clamps the net partially biased toward one side or the other side, wherein the first clamping portion and the second clamping portion are connected to each other, the engagement means are provided at multiple locations and can be released after engagement, and the fitting means is provided in a ring shape.

[0015] Another specific example of a net holder of the present invention includes a first clamping portion arranged along one side of the net, a second clamping portion arranged along the other side of the net, an opening that penetrates while the first clamping portion and the second clamping portion are arranged opposite each other, and an engagement means that joins the opposing first clamping portion and second clamping portion to clamp the net, wherein the first clamping portion and the second clamping portion are connected to each other, the engagement means are provided at multiple locations and can be released after engagement, and the joining position can be adjusted in multiple stages in the spacing direction between the first clamping portion and the second clamping portion that clamp the net.

[0016] Furthermore, another specific example of a net holder of the present invention includes a first clamping portion arranged along one side of the net, a second clamping portion arranged along the other side of the net, an opening that penetrates while the first clamping portion and the second clamping portion are arranged opposite each other, and an engagement means that connects the opposing first clamping portion and second clamping portion to clamp the net, wherein the first clamping portion and the second clamping portion are separate from each other, the engagement means are releasable after engagement and are provided in multiple locations, and the connection position can be adjusted in multiple stages in the spacing direction between the first clamping portion and the second clamping portion that clamp the net.

[0017] It is desirable that each of the net holders described above is formed using an environmentally friendly material that contains plant-derived components. Effect of the Invention

[0018] According to the present invention, the net is clamped in a planar manner between the first clamping portion and the second clamping portion, so that even if a load is applied to the net, the stress will not be concentrated on a particular mesh of the net, but will be distributed over the net clamped between the first clamping portion and the second clamping portion. In other words, openings (grommets) are provided within the clamping area formed by the first clamping portion and the second clamping portion which clamp the net in a flat plane, so that the stress exerted when the net is pulled is received by an area rather than a point, thereby reducing damage to the mesh of the net.

[0019] Therefore, it is possible to provide a net holder that can efficiently and easily install a net even if the net does not have grommets, and that can hold the net while preventing it from being damaged. In addition, the net holder of the present invention can be attached not only to the ends (corners or edges) of the net, but also in the middle, making it possible to efficiently adjust the size of the net by joining the nets together, and to efficiently repair damaged areas by overlapping and clamping the nets.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the net holder according to the present invention will be described with reference to the drawings. The net holder of the present invention is intended to hold and install a net efficiently and easily while preventing damage to the net even when the net does not have grommets. Also, the net holder of the present invention is intended to make it possible to easily join nets together or repair damaged areas without weaving the net with string or thread when the dimensions of the net do not match or the net is damaged.

[0022] In addition, the embodiments described below are preferred specific examples of the present invention, and therefore various technical limitations are imposed thereon. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0023] <First embodiment> As shown in FIGS. 1 to 3, a net holder 10 in this embodiment includes at least a first clamping portion 1 and a second clamping portion 2. As shown in FIG. The first clamping portion 1 is a planar member disposed along one side of the highly flexible net N, and has a size sufficient to cover a plurality of meshes M. In addition, the second clamping portion 2 is a planar member arranged along the other side of the net N so as to face the first clamping portion 1, and has the same size as the first clamping portion 1 which covers the multiple meshes M.

[0024] The first clamping portion 1 and the second clamping portion 2 are connected to each other at one end of their respective peripheries by a generally band-shaped connecting piece 6. In other words, since the first clamping portion 1 and the second clamping portion 2 are used as a pair, they can be easily arranged opposite each other without losing one of them.

[0025] The first clamping part 1 has an opening 3 penetrating from one side to the other side in a state in which it is disposed opposite the second clamping part 2. This opening 3 is a portion that functions as a grommet used to fasten the net holder 10 to a post P or the like through a fixing member C such as a string, wire, or cable tie when installing the net holder 10 in a desired position.

[0026] The net holder 10 further includes an engagement means 4. The engagement means 4 couples the opposing first clamping portion 1 and second clamping portion 2 in a planar manner so as to overlap each other, and functions to maintain the clamped state of the net N. The engaging means 4 may be, for example, a hook type consisting of a protruding engaging claw 41 and an engaging opening 42. The engaging claw 41 has a tip curved into a hook shape and can be inserted into the engaging opening 42. When the engaging claw 41 is inserted into the engaging opening 42, it is elastically deformed by bending in the direction opposite to the bending direction of the tip, and returns to its original state by passing through the engaging opening 42, and engages with the edge of the engaging opening 42. Therefore, the engaging means 4 firmly holds the net N by maintaining the coupled state of the first clamping portion 1 and the second clamping portion 2.

[0027] The engaging means 4, which is composed of the engaging claws 41 and the engaged openings 42, has a reversible structure that can be disengaged after engagement, i.e., it is possible to disengage and pull out the engaging claws 41 inserted into the engaged openings 42. In this way, the engaging means 4 that can be disengaged after engagement allows the net holder 10 to be attached to the net N when needed and detached from the net N when not needed, allowing the net holder 10 to be used repeatedly and efficiently without waste.

[0028] Moreover, the engaging means 4 is provided at a plurality of locations within the clamping area of ​​the net N by the first clamping portion 1 and the second clamping portion 2. The plurality of engaging means 4 holds the net N more firmly and uniformly in a plane, and even if the net N is pulled and a load is applied to the openings (grommets) 3, the load is not concentrated at one point on the mesh M of the net N, and the stress is distributed in a plane, making it possible to further reduce damage to the mesh M of the net N.

[0029] The net holder 10 further includes a fitting means 5. The fitting means 5 functions to clamp the net N partially biased toward one side or the other side. In other words, the net N is clamped non-planarly by the fitting means 5 between the first clamping portion 1 and the second clamping portion 2 with a bent portion so that the recessed portion and the protruding portion fit together, so that the net N is held even more firmly.

[0030] The fitting means 5 can be, for example, composed of a fitting protrusion 51 and a fitting opening 52. The fitting protrusion 51 is a portion formed by protruding so that the central portion, excluding the peripheral portion of the first clamping portion 1, is positioned toward the other surface side of the net N, and the fitting opening 52 is a portion formed by opening the central portion, excluding the peripheral portion of the second clamping portion 2. That is, the fitting protrusion 51 fits into the fitting opening 52 to clamp the net N. The fitting opening 52 also functions as a grommet, similar to the opening 3 provided in the first clamping portion 1. In this fitting means 5, it is desirable that the fitting region between the fitting protrusion 51 and the fitting opening 52 is formed in an annular (circular) shape.

[0031] The fitting means 5 consisting of such fitting protrusions 51 and fitting openings 52 can disperse the stress by the fitting means 5 and further reduce breakage of the net N even if the net N is pulled and a load is applied to the openings (grommets) 3, without concentrating the load on one point of the mesh M of the net N. Moreover, by fitting and holding the net N in an annular shape, the stress applied to the net N can be dispersed and reduced in a planar manner in the annular region held by the fitting means 5.

[0032] 2 and 3, the first clamping part 1 is shown as having an elliptical outer shape, a fitting protrusion 51 that protrudes elliptical in the center except for the peripheral edge, and a small elliptical opening 3 in the fitting protrusion 51. The first clamping part 1 is also shown as having three locking claws 41 formed in an elliptical annular region of the peripheral edge. On the other hand, the second clamping part 2 is shown as having an elliptical outer shape like the first clamping part 1, a fitting opening 52 that is open elliptical in the center except for the peripheral edge, and three locked openings 42 formed in the elliptical annular region of the peripheral edge at positions facing the locking claws 41 of the first clamping part 1.

[0033] The net holder 10 thus formed is molded using an environmentally friendly material that contains plant-derived components (biomass). In other words, in recent years, there has been a demand for reducing the environmental load by reducing waste. In addition, synthetic resin products emit a large amount of CO2 (carbon dioxide) at each stage, from the mining and transportation of petroleum, which is the raw material for synthetic resin, and from the production and disposal of synthetic resin. In recent years, there has been a demand for reducing CO2 in order to address environmental issues such as global warming caused by greenhouse gases such as CO2.

[0034] Therefore, it is desirable to mold using plant-derived materials such as bioplastics, which are environmentally friendly. Various developments in bioplastics are underway around the world, but the materials that are most widely produced and attracting attention are BioPE (biopolyethylene), PLA (polylactic acid), PHA (polyhydroxyalkanoate), and PBS (polybutylene succinate) and PA11 (nylon 11), which are made from biomass raw materials.

[0035] These are plastics that are produced partially or entirely from biomass raw materials (derived from plants) and are highly regarded as environmentally friendly materials. A representative example is PLA, which is widely mass-produced and distributed mainly in North America and Asia, with global production volume in 2019 being approximately 290,000 tons, and is expected to double within the next few years.

[0036] PLA is produced from sugarcane and corn. PBS, which uses some biomass raw materials, is produced from succinic acid and butanediol. These plants contain a component called polysaccharide, but both polysaccharides and petroleum have the same basic molecular structure, and are composed of C, H, and O in the chemical formula. When polysaccharides are extracted from plants and subjected to heat or slight structural changes for chemical synthesis, they become a material with the functions of plastic.

[0037] Moreover, biodegradable resins such as PLA, PHA, and PBS undergo hydrolysis in compost or soil in environments with appropriate humidity and temperature after use, and are ultimately decomposed into CO2 and water by the action of microorganisms within a few months. They are already widely used commercially, and are used in disposable plastic cups and cutlery, take-out lunch containers, garbage bags, etc. Using plant-derived plastics as bioplastics can help achieve decarbonization. Therefore, when bioplastics are used, even if they are left behind after use, they will return to nature and there is no need to worry about environmental pollution, making them desirable.

[0038] In the above-described embodiment, it has been described that an opening (grommet) 3 is formed in the first clamping portion 1, and that a locking claw 41 of the locking means 4 and a mating protrusion 51 of the fitting means 5 are formed, and that a locked opening 42 of the locking means 4 and a mating opening 52 of the fitting means 5 are formed in the second clamping portion 2, but the structures of the first clamping portion 1 and the second clamping portion 2 may be reversed. That is, the first clamping portion 1 may be formed with an engaging opening 42 for the locking means 4 and an engaging opening 52 for the engaging means 5, and the second clamping portion 2 may be formed with an opening (grommet) 3, and also with an engaging claw 41 for the locking means 4 and an engaging protrusion 51 for the engaging means 5.

[0039] The net holder 10 formed as described above is assembled, for example, by disposing the second clamping portion 2 on the other side of the net N, and bending the connecting piece 6 so that the opposing inner surfaces of the first clamping portion 1 and the second clamping portion 2 come together, as shown by the outlined arrow in Fig. 3. In this way, the first clamping portion 1 is disposed on one side of the net N, the fitting protrusion 51 fits into the fitting opening 52, and the net N is partially biased towards the other side and is clamped by the net holder 10. Furthermore, the hook-shaped portion at the tip of the locking claw 41 is inserted into the locking opening 42 and locked to the edge, thereby connecting the first clamping part 1 and the second clamping part 2. Then, the net N is firmly held by the net holder 10 while maintaining the state of being sandwiched between the first clamping part 1 and the second clamping part 2.

[0040] Then, a fixing member C such as a string, wire, or cable tie is passed through an opening 3 provided in the first clamping portion 1, and this fixing member C is fastened to a support P or the like. In this case, it is preferable to use a cable tie as the fixing member C, since this makes the installation itself easy and allows the fixing member C to be fastened to the support P or the like without having to worry about loosening or damage. As a result, even if the net N does not have grommets, the net N can be efficiently and easily installed in a desired position using the net holder 10 of this embodiment. Moreover, since the net N is sandwiched in a plane by the net holder 10, the stress when the net N is pulled is received by an area rather than a point, and damage to the mesh M of the net N can be reduced.

[0041] Second embodiment In addition, in the present invention, the net N can be appropriately clamped according to its thickness. That is, even if the thread or string constituting the net N is thick, or if the thickness increases by stacking a plurality of nets N, the engaging means 4 is structured to be able to adjust the joining position between the first clamping portion 1 and the second clamping portion 2 in multiple stages according to the thickness, which is different from the first embodiment described above.

[0042] In the following, the following embodiments will be described with a focus on the differences from the first embodiment. Therefore, the same components as those in the first embodiment are given the same reference numerals and the description thereof is omitted, and they are considered to be the same unless otherwise specified.

[0043] 4 to 6, the net holder 20 in this embodiment includes at least a first clamping portion 1 and a second clamping portion 2. The first clamping portion 1 and the second clamping portion 2 are connected to each other by a generally band-shaped connecting piece 6 at one end side of the peripheral portion.

[0044] The first clamping portion 1 and the second clamping portion 2 each have an opening 3 penetrating from one side to the other side when they are arranged opposite each other. As in the first embodiment, these openings 3, 3 function as grommets used to fasten the net holder 20 to a post P or the like through a fixing member C such as a string, wire, or cable tie when installing the net holder 20 in a desired position.

[0045] The net holder 20 further includes an engagement means 4. The engagement means 4 couples the opposing first clamping portion 1 and second clamping portion 2 in a planar manner so as to overlap each other, thereby maintaining the clamped state of the net N. The engagement means 4 can be, for example, a ratchet type consisting of a protrusion 43 shaped like a barb of a fishhook provided on the locking piece 7 and a retaining portion 44 shaped like a barb of a fishhook provided on the retaining piece 8 provided in the locking piece insertion port 9.

[0046] The locking piece 7 is a flat plate-like portion formed on the inner surface side of the first clamping part 1, and has a plurality of protrusions 43··43 formed in a sawtooth shape on one side. The removal prevention piece 8 is a flat plate-like portion formed on the outer surface side within the locking piece insertion opening 9 formed to penetrate the second clamping part 2 and having a size allowing the locking piece 7 to be inserted, and has a plurality of removal prevention portions 44··44 formed in a sawtooth shape on the surface corresponding to the one side of the locking piece 7. In other words, the removal prevention portion 44 is formed on one side of the locking piece 8 that faces the protrusion 43 formed on the locking piece 7 when the locking piece 7 is inserted into the locking piece insertion opening 9.

[0047] When the locking piece 7 is inserted into the locking piece insertion opening 9 and the protrusion 43 comes into contact with the retaining portion 44, it is bent and elastically deformed in the opposite direction to the side on which the protrusion 43 is formed, and the protrusion 43 overcomes the retaining portion 44, thereby returning to the original state. At this time, the protrusion 43 of the locking piece 7 and the retaining portion 44 of the retaining portion 44 engage with each other, and the first clamping portion 1 and the second clamping portion 2 are maintained in a joined state to clamp the net N.

[0048] Further, the engaging means 4 is capable of adjusting the engaging position in multiple stages in the spacing direction between the first clamping portion 1 and the second clamping portion 2 that clamp the net N. That is, a plurality of protrusions 43··43 are formed in a sawtooth shape along the length direction (standing direction) of one surface side of the locking piece 7, and a plurality of retaining portions 44··44 are also formed in a sawtooth shape along the length direction (standing direction) of one surface side of the retaining piece 8.

[0049] In Figure 7, as an example, four protrusions 43a, 43b, 43c, and 43d are shown formed on one side of the locking piece 7, and four retention portions 44a, 44b, 44c, and 44d are shown formed on one side of the locking piece 8. Therefore, when the locking piece 7 is inserted into the locking piece insertion port 9 as indicated by the white arrow in the figure, the first engagement position is reached in which the first convex portion 43a of the locking piece 7 and the first retaining portion 44a of the retaining piece 8 are engaged with each other. Also, a second coupling position can be established in which the first protrusion 43a of the locking piece 7 and the second retaining portion 44b of the retaining piece 8 are engaged with each other, and the second protrusion 43b of the locking piece 7 and the first retaining portion 44a of the retaining piece 8 are engaged with each other. Also, a third coupling position can be established in which the first protrusion 43a of the locking piece 7 and the third retaining portion 44c of the retaining piece 8, the second protrusion 43b of the locking piece 7 and the second retaining portion 44b of the retaining piece 8, and the third protrusion 43c of the locking piece 7 and the first retaining portion 44a of the retaining piece 8 are engaged with each other. Furthermore, a fourth connecting position can be obtained in which the first protrusion 43a of the locking piece 7 and the fourth retention portion 44d of the locking piece 8, the second protrusion 43b of the locking piece 7 and the third retention portion 44c of the locking piece 8, the third protrusion 43c of the locking piece 7 and the second retention portion 44b of the locking piece 8, and the fourth protrusion 43d of the locking piece 7 and the first retention portion 44a of the locking piece 8 are engaged with each other.

[0050] In this way, the engaging means 4 has a structure that allows the joining position between the first clamping portion 1 and the second clamping portion 2 to be adjusted in multiple stages, so that even if the thread or string constituting the net N is thick or the thickness increases by stacking multiple nets N...N, the net N can be securely held in accordance with the thickness. Therefore, it can be applied to various types of nets N, and if the net N is damaged, it is possible to easily repair the damaged area by stacking the nets N without weaving the net N with string or thread.

[0051] The engaging means 4 composed of the protrusion 43 and the retaining portion 44 has a reversible structure that can be disengaged after engagement, that is, the engagement between the protrusion 43 and the retaining portion 44 can be released and the retaining piece 8 can be pulled out. Specifically, for example, as shown by the black arrow in Fig. 7, the engagement between the protrusion 43 of the retaining piece 7 inserted into the retaining piece insertion hole 9 and the retaining portion 44 of the retaining piece 8 provided in the retaining piece insertion hole 9 can be released and the retaining piece 8 can be pulled out by tilting the tip 8a of the retaining piece 8 to the opposite side from the side on which the retaining portion 44 is formed, thereby allowing the retaining piece 7 to be pulled out. With such engaging means 4 that can be disengaged after engagement, the net holder 10 can be attached to the net N when needed and removed from the net N when not needed, allowing the net holder 10 to be used repeatedly and efficiently without waste.

[0052] Furthermore, the engaging means 4 are provided at multiple locations within the clamping area of ​​the net N by the first clamping portion 1 and the second clamping portion 2. The net N is held even more firmly by the multiple engaging means 4, and even if the net N is pulled and a load is applied to the openings (grommets) 3, the load is not concentrated at one point on the mesh M of the net N, and the stress is distributed two-dimensionally, making it possible to further reduce damage to the mesh M of the net N.

[0053] In Figures 4 to 6, the engagement means 4 is shown as having three locking pieces 7 (and protrusions 43) formed on the inner surface side of the first clamping portion 1 so as to surround an opening (grommet) 3 provided in the clamping area, and three locking piece insertion holes 9 and removal pieces 8 (and removal portions 44) formed at opposing positions in the second clamping portion 2.

[0054] The net holder 20 thus formed is also molded using an environmentally friendly material that contains only plant-derived components (biomass).

[0055] The net holder 20 formed as above can also clamp and firmly hold the net N, similar to the net holder 10 in the first embodiment described above. Then, by passing a fixing member C such as a cable tie through the openings 3, 3 provided in the first clamping portion 1 and the second clamping portion 2, respectively, and connecting this fixing member C to a support P, the net N can be efficiently and easily installed in a desired position using the net holder 20 of this embodiment, even if the net N does not have grommets. Therefore, since the net N is clamped in a plane by the net holder 20, the stress when the net N is pulled is received by a surface rather than a point, thereby reducing damage to the mesh M of the net N.

[0056] <Third embodiment> In addition, in the present invention, the installation position on the net N is not limited and can be freely installed. That is, the first clamping part 1 and the second clamping part 2 are structured to be separated from each other so that the net N can be installed not only at the corners or periphery of the net N but also in the middle of the net N, which is different from the first and second embodiments described above.

[0057] As shown in Fig. 8, the net holder 30 in this embodiment includes at least a first clamping portion 1 and a second clamping portion 2. The first clamping portion 1 and the second clamping portion 2 are separate from each other.

[0058] Moreover, the net holder 30 of this embodiment further includes an engagement means 4. This engagement means 4 couples the opposing first clamping portion 1 and second clamping portion 2 in a planar manner to maintain the clamped state of the net N. As for the engagement means 4, as in the second embodiment, it may be of a ratchet type consisting of, for example, a protrusion 43 shaped like a barb of a fishhook provided on the locking piece 7, and a retaining portion 44 shaped like a barb of a fishhook provided on the retaining piece 8 inside the locking piece insertion port 9.

[0059] The engaging means 4 has a plurality of protrusions 43··43 formed in a sawtooth shape along the length direction (standing direction) of one surface side of the locking piece 7, and also has a plurality of retaining portions 44··44 formed in a sawtooth shape along the length direction (standing direction) of one surface side of the retaining piece 8, so that the engaging position can be adjusted in multiple stages in the spacing direction between the first clamping portion 1 and the second clamping portion 2 that clamp the net N. Furthermore, the engaging means 4 is provided at a plurality of locations within the clamping area of ​​the net N between the first clamping portion 1 and the second clamping portion 2.

[0060] The net holder 30 thus formed is also desirably formed using an environmentally friendly material that contains only plant-derived components (biomass).

[0061] In this way, since the first clamping part 1 and the second clamping part 2 are structured to be separated from each other, the net N can be easily attached by overlapping not only at the corners or peripheral parts of the net N but also near the center of the net N. Therefore, even if the dimensions do not match the installation location of the net N, the net N can be installed efficiently and easily by connecting the net N together or shortening it. In addition, the net N can be partially overlapped and held to prevent damage to the net N.

[0062] The net holder 30 formed as above can also clamp and firmly hold the net N, similar to the net holder 10 in the first embodiment and the net holder 20 in the second embodiment described above. Moreover, the installation position on the net N is not limited, and it can be installed in a wide variety of positions. [Industrial Applicability]

[0063] The net holder of the present invention is expected to be widely used to hold and prevent damage to nets for various purposes, such as animal-proof nets, bird-proof nets, windbreak nets, and shading nets, as well as to connect nets together and repair damaged areas. [Explanation of symbols]
