Rope end buckles and their male buckles

Abstract

This invention discloses a rope end buckle and its male buckle. The male buckle includes an end cap, a structural beam vertically connected to the end cap, two first side wing plates extending from one side of the structural beam, and two second side wing plates extending from the other side of the structural beam and corresponding to the two first side wing plates respectively. Each first side wing plate has a first lever arm rib, and each second side wing plate has a second lever arm rib, both adjacent to the end cap and not perpendicular to the structural beam. The two second lever arm ribs correspond to the two first lever arm ribs respectively. The space between each first side wing plate and the corresponding second side wing plate can be used to set a rope end segment, which is clamped by the first lever arm rib and the second lever arm rib. Accordingly, by ensuring that each first lever arm rib and the corresponding second lever arm rib are not perpendicular to the structural beam, the torque and clamping force are effectively increased.

[0028] [Example 1]

[0029] Please see Figures 1 to 9 As shown, this is an embodiment of the present invention. Figures 1 to 4 As shown, this embodiment discloses a rope end buckle 100 for securing two rope end segments 200. The rope end buckle 100 includes a female buckle 1 and a male buckle 2 detachably mounted to the female buckle 1. It should be noted that although the rope end buckle 100 is described in this embodiment with the female buckle 1 paired with the male buckle 2, the invention is not limited thereto. For example, in other embodiments not shown in this invention, the male buckle 2 can also be used alone (e.g., for sale) or in conjunction with other components.

[0030] like Figures 5 to 7 As shown, in this embodiment, the female buckle 1 is generally tubular and has an assembly channel 11 that extends through a length direction L. The assembly channel 11 includes a first opening 111 and a second opening 112 located at opposite ends, and the assembly channel 11 has two stop protrusions 113 formed near the first opening 111, which face each other along a thickness direction H perpendicular to the length direction L.

[0031] Furthermore, the female buckle 1 preferably has two compartmentalized protrusions 12 located within the second opening 112 to divide the second opening 112 into two interconnected rope holes 1121, so that the two rope tails 200 can pass through the assembly channel 11 of the female buckle 1 along the length direction L through the two rope holes 1121 respectively.

[0032] More specifically, the two compartment protrusions 12 face each other along the thickness direction H and are each approximately triangular, and the two rope holes 1121 are interconnected along a width direction W perpendicular to the thickness direction H and the length direction L, so that the outlines of the two rope holes 1121 are approximately figure-eight shaped, but the present invention is not limited thereto.

[0033] The male buckle 2 is detachably inserted into the assembly channel 11 of the female buckle 1. In this embodiment, the male buckle 2 includes a tail cap 21, a structural beam 22 vertically connected to the tail cap 21, a free end 23 connected to the end of the structural beam 22, a plurality of inserts 24 connected to the structural beam 22 and the free end 23, two first side plates 25 connected to the structural beam 22 and located on one side of the plurality of inserts 24, and two second side plates 26 connected to the structural beam 22 and located on the other side of the plurality of inserts 24. However, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the male buckle 2 may omit or adjust the free end 23 and / or the inserts 24 according to design requirements.

[0034] like Figure 3 and Figures 5 to 8 As shown, in this embodiment, the tail cap 21 closes one end of the assembly channel 11 (that is, the tail cap 21 is located inside the first opening 111 and closes the first opening 111). The structural beam 22, the plurality of the inserts 24, the two first side wing plates 25 and the two second side wing plates 26 are all located inside the assembly channel 11, while the free end 23 is located inside the second opening 112.

[0035] The structural beam 22 is generally cuboid and has two long side edges 221 adjacent to the inner wall of the assembly channel 11, two wide surfaces 222 generally perpendicular to the width direction W, and an end face 223 away from the tail cap 21. Each of the long side edges 221 of the structural beam 22 has an interference protrusion 27, and the two interference protrusions 27 of the structural beam 22 abut against the two stop protrusions 113 of the female buckle 1, thereby restricting the relative movement of the male buckle 2 and the female buckle 1 along the length direction L.

[0036] Furthermore, the free end 23 is formed on the end face 223 of the structural beam 22, and the free end 23 has two guide grooves 231 respectively adjacent to the two long side edges 221. The two compartment protrusions 12 of the female buckle 1 are respectively located within the two guide grooves 231 of the male buckle 2, thereby stably maintaining the relative positions of the female buckle 1 and the male buckle 2.

[0037] like Figure 2 , Figure 5 and Figure 9 As shown, two first side wing plates 25 are formed by extending in opposite directions from one of the long side edges 221, and two second side wing plates 26 are formed by extending in opposite directions from the other long side edge 221. The two second side wing plates 26 correspond to (e.g., face) the two first side wing plates 25 along the thickness direction H. In this embodiment, the two first side wing plates 25 and the two second side wing plates 26 are preferably arranged in a mirror-symmetrical configuration corresponding to the structural beam 22, but the invention is not limited thereto.

[0038] Furthermore, the space between each first side wing plate 25 and the corresponding second side wing plate 26 is connected to one of the rope holes 1121 of the female buckle 1 and can be used to provide one of the rope tail segments 200. The plurality of the inserts 24 are respectively connected to the two wide surfaces 222 and the free end 23 of the structural beam 22, and at least one insert 24 is disposed between each first side wing plate 25 and the corresponding second side wing plate 26, which is pyramidal in shape for inserting into the corresponding rope tail segment 200.

[0039] More specifically, each of the first side wing plates 25 has a first plate body 251, a first lever arm rib 252 connected to the first plate body 251 and adjacent to the tail cap 21, a first limiting tooth 253 connected to the end of the first lever arm rib 252, and a first protrusion 254 located on the opposite side of the first limiting tooth 253. In this embodiment, each of the first lever arm ribs 252 is not perpendicular to the structural beam 22 and is preferably connected to the structural beam 22 along a first predetermined acute angle σ1, so as to collectively form a first rope placement notch 255 facing the tail cap 21.

[0040] Furthermore, each of the second side wing plates 26 has a second plate body 261, a second lever arm rib 262 connected to the second plate body 261 and adjacent to the tail cap 21, a second limiting tooth 263 connected to the end of the second lever arm rib 262, and a second protrusion 264 located on the opposite side of the second limiting tooth 263. In this embodiment, each of the second lever arm ribs 262 is not perpendicular to the structural beam 22 and is preferably connected to the structural beam 22 along a second preset acute angle σ2, so as to jointly form a second rope placement notch 265 facing the tail cap 21. Herein, the first preset acute angle σ1 is equivalent to the second preset acute angle σ2 in this embodiment, but is not limited thereto.

[0041] It should be noted that the two second lever arm ribs 262 correspond to the two first lever arm ribs 252 along the thickness direction H, and each first lever arm rib 252 and its corresponding second lever arm rib 262 can be used to clamp the corresponding rope tail segment 200. Accordingly, in this embodiment, the male buckle 2 can increase its torque and clamping force by ensuring that each first lever arm rib 252 and its corresponding second lever arm rib 262 are not perpendicular to the structural beam 22 (e.g., preferably forming a first preset acute angle σ1 and a second preset acute angle σ2), thereby enabling it to clamp the corresponding rope tail segment 200 more securely.

[0042] Furthermore, each of the first limiting teeth 253 faces a second limiting tooth 263 along the thickness direction H, to jointly confine the corresponding rope tail segment 200 to its inner side, thereby further engaging with the corresponding first lever arm rib 252 and second lever arm rib 262. That is, each of the first limiting teeth 253 and the corresponding second limiting teeth 263 can be assembled with the corresponding rope tail segment 200 (e.g., during assembly). Figure 9 This more effectively restricts the rope tail segment 200 from coming off along the width direction W.

[0043] Furthermore, the first limiting tooth 253 and the first protrusion 254 of each of the first side wing plates 25 are configured along the thickness direction H with the corresponding second limiting tooth 263 and the second protrusion 264 of the second side wing plate 26. Accordingly, in this embodiment, the rope tail buckle can be pressed by the assembly channel 11 through the first protrusion 254 of each of the first side wing plates 25 and the second protrusion 264 of the corresponding second side wing plates 26, thereby increasing the force with which the corresponding first lever arm rib 252 and the second lever arm rib 262 clamp the rope tail segment 200, and further strengthening the effect of the corresponding first limiting tooth 253 and the second limiting tooth 263 confining the rope tail segment 200 to its inner side.

[0044] [Example 2]

[0045] Please see Figure 10 As shown, this is Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment One are roughly explained as follows:

[0046] In this embodiment, the male buckle 2 of the rope end buckle 100 can be used to assemble within the assembly channel 11 of another female buckle 1a, 1b, 1c, 1d, and the shape of the other female buckle 1a, 1b, 1c, 1d is different from that of the female buckle 1, while the assembly channel 11 of the other female buckle 1a, 1b, 1c, 1d is the same as that of the female buckle 1. That is, the male buckle 2 can be selectively assembled into one of a plurality of female buckles 1, 1a, 1b, 1c, 1d with different shapes.

[0047] Accordingly, the rope end buckle 100 disclosed in this embodiment forms the same assembly channel 11 through a plurality of female buckles 1, 1a, 1b, 1c, and 1d that can be matched with the male buckle 2. Therefore, the male buckle 2 can be selectively matched with female buckles 1, 1a, 1b, 1c, and 1d with specific shapes according to design requirements. Thus, when facing different shape requirements, only the female buckles 1, 1a, 1b, 1c, and 1d that belong to the appearance parts need to be produced, thereby reducing the overall cost and effectively shortening the delivery time.

[0048] [Technical Effects of the Embodiments of the Invention]

[0049] In summary, the rope tail buckle and its male buckle disclosed in the embodiments of the present invention improve their torque and clamping force by ensuring that each of the first lever arm ribs and the corresponding second lever arm ribs is not perpendicular to the structural beam (e.g., forming the first preset acute angle and the second preset acute angle, or further limiting their angle range), thereby enabling them to clamp the corresponding rope tail segment more stably.

[0050] Furthermore, the rope tail buckle disclosed in the embodiments of the present invention can also effectively improve the clamping or positioning effect of the corresponding rope tail segment through the structural design of the first side wing plate and the second side wing plate (e.g., forming a first limiting tooth and a second limiting tooth that match each other, or further forming a first protrusion and a second protrusion that match each other).

[0051] The content disclosed above is only a preferred and feasible embodiment of the present invention, and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the patent scope of the present invention.
