[0015] It will be clear that when an element (or device) is stated to be "connected" to another element, the connection can be direct or indirect, meaning that intermediate elements may be present. However, when an element is stated to be "directly connected" to another element, no intermediate elements are present. Furthermore, the terms first, second, third, etc., are used here to describe different elements or components, and these elements or components should not be limited by these terms. Consequently, a first element or component discussed later could also be referred to as a second element or component.Furthermore, a combination of these elements (units or systems) of the present disclosure is not a common combination in this technical field; therefore, it cannot be predicted whether a person skilled in the art can easily realize a connection of the combination using these elements (units or systems).
[0016] Fig. Figure 1 is a three-dimensional schematic view of a buckle device 100 according to the first embodiment of the present disclosure. Fig. Figure 2 is an exploded view of the buckle device 100 according to the first embodiment in Fig. 1. Fig. Figure 3 is a top view of the male buckle part 120 decoupled from the female buckle part 110 according to the first embodiment in Fig. 1. Fig. Figure 4 is a top view of the male buckle part 120 in engagement with the female buckle part 110 according to the first embodiment in Fig. 1. How Fig. 1, Fig. 2, Fig. 3 to Fig. As shown in Figure 4, the buckle device 100 comprises a female buckle part 110 and a male buckle part 120. The female buckle part 110 has a wall that forms an insertion hole 111. The male buckle part 120 comprises a male buckle part body 121, two engagement sections 122, an elastic connecting element 123, and an actuating element 124. The two engagement sections 122 are spaced apart on the male buckle part body 121 and are located on an insertion side of the male buckle part body 121. The two engagement sections 122 are configured to engage with the insertion hole 111 of the female buckle part body 110. The elastic connecting element 123 is connected between the two engagement sections 122.The actuating element 124 has an actuating section 1241 and a connecting cord 1242. One of the two ends of the connecting cord 1242 is connected to the actuating section 1241, and the other end of the connecting cord 1242 is connected to the elastic connecting element 123. When the two engagement sections 122 of the male buckle part 120 are engaged with the insertion hole 111 of the female buckle part 110, and an external force is applied to the actuating section 1241 to bend the elastic connecting element 123, the two engagement sections 122 close together to disengage from the insertion hole 111.
[0017] More precisely, the configuration of the actuating element 124 allows a user to actuate the two engagement sections 112 so that they can be disengaged from the female buckle part 110 without manual contact. This circumvents the miniaturization problem caused by the size and structure of the conventional buckle device, which is limited by the disengagement mechanism. This allows the buckle device 100 to be reduced in size and its design tolerances to be increased, thus improving its versatility. In particular, the overall length of the buckle device 100 can be reduced to less than 30 mm. In the first embodiment, the overall length of the buckle device 100 can be 28.93 mm, but this is not the limit of the present disclosure.
[0018] According to Fig. 2 and Fig. 3 The elastic connecting element 123 can be arc-shaped, and the elastic connecting element 123 has two legs 1231 and a vertex arc 1232. Each of the two legs 1231 is integrally connected to an inner side of each of the two engagement sections 122, and the vertex arc 1232 is integrally connected between the two legs 1231 and closer to the male buckle part body 121 than the two legs 1231 are to the male buckle part body 121.Due to the arc structure of the elastic connecting element 123, when the actuating section 1241 is pulled in a direction away from the female buckle part 110, the connecting cord 1242 pulls on the apex arc 1232, causing it to contract and deform. This, in turn, causes the two legs 1231 to pull on the two engagement sections 122, closing the two engagement sections 122 together so that they can be disengaged from the female buckle part 110. This improves the ease of disengaging the two engagement sections 122.
[0019] Furthermore, the elastic connecting element 123 can also have a projection 1233. The projection 1233 is located at the apex 1232, and the connecting cord 1242 is held on the projection 1233. More precisely, the connecting cord 1242 is wrapped around the projection 1233 to fix a position at which the actuating section 1241 pulls on the elastic connecting element 123. According to Fig. 3 the projection 1233 is located in the middle of the apex arch 1232, so that the other end of the connecting cord 1242 is attached in the middle of the apex arch 1232, after which a position of the elastic connecting element 123 is necessarily fixed in the middle, so that the two engagement sections 122 can be pulled symmetrically.
[0020] Fig. Figure 5 is a cross-sectional view of the male buckle part 120 in engagement with the female buckle part 110 according to the first embodiment in Fig. 4. According to Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5 The female buckle part 110 can further have two barbed grooves 114. The two barbed grooves 114 are arranged in the wall and communicate with the insertion hole 111. Each of the two engagement sections 122 has a hook part 1221 and a leg part 1222, each of the two hook parts 1221 is integrally connected to each of the leg parts 1222, each of the two leg parts 1222 is connected to the male buckle part body 121, and each of the two hook parts 1221 is configured to engage with each of the two barbed grooves 114.If the two engagement sections 122 are in engagement with the insertion hole 111 due to the configuration of the two hook parts 1221 and the two barbed grooves 114, it can be prevented that each of the two hook parts 1221 is disengaged from each of the two barbed grooves by an external force; if a force is applied to the actuating section 1241, the two hook parts 1221 are closed towards each other in order to be disengaged from the two barbed grooves 114.
[0021] Furthermore, the two leg sections 1222 can be inclined towards each other, and an included angle can be formed between them. The included angle between the two leg sections 1222 is, in particular, 22 degrees, although this is not the limit of the present disclosure. Thus, when the two engagement sections 122 are brought into engagement with the insertion hole 111, each of the two hooking parts 1221 can fit into the insertion hole 111 by an interference fit along an inclination direction of each of the two leg sections 1222.
[0022] According to Fig. 2 and Fig. 5. Each of the two engagement sections 122 can further have a mounting structure 1223 located at one end of each of the two leg parts 1222 near the male buckle part body 121. The wall can have two side wall sections, and the two mounting structures 1223 are each configured to abut the two side wall sections. The two mounting structures 1223 abutting the two side wall sections reduce the gap between the two engagement sections 122 and the wall, thereby reducing noise caused by vibration between the female buckle part 110 and the male buckle part 120.
[0023] Furthermore, the female buckle part 110 can also have several stiffening ribs 113. The wall also has an upper wall section 1111 and a lower wall section 1112, and the stiffening ribs 113 are located in the insertion hole 111 and are arranged between the upper wall section 1111 and the lower wall section 1112. The configuration of the stiffening ribs 113 improves the structural strength and stability of the female buckle part 110, thereby reducing the deformation of the buckle device 100 due to external twisting.
[0024] Furthermore, the female buckle part 110 can also have a retaining groove 112, which is arranged on the wall of the female buckle part 110 and communicates with the insertion hole 111, and the retaining groove 112 is configured such that the connecting cord 1242 passes through it. According to Fig. 4. The retaining groove 112 can be arranged on the upper wall section 1111, and the retaining groove 112 is radially narrowed to form a cord-holding structure. When the male buckle part 120 engages with the female buckle part 110, the user can retain the connecting cord 1242 in the retaining groove 112 by means of the cord-holding structure, thus preventing the connecting cord 1242 from dangling excessively during use of the buckle device 100 and making it less likely that the connecting cord 1242 will unintentionally snag on other objects.
[0025] According to Fig. 2 and Fig. 3. The male buckle body 121 can have a frame body and a horizontal bar 1214. The frame body has two first bar sections 1211, 1212 and two second bar sections 1213. The two first bar sections 1211, 1212 are connected to the two second bar sections 1213 to form a rectangle, and the first bar section 1211 is configured to connect the two engagement sections 122. The horizontal bar 1214 is connected between the two second bar sections 1213, and the horizontal bar 1214 has several toothed structures 1215 that point towards the first bar section 1211.In particular, the frame body formed by the first rod sections 1211, 1212 and the second rod sections 1213 can be provided for a strap that is connected to the male buckle part in such a way that it is wrapped around it, and the serrated structures 1215 can improve the frictional force between the strap and the male buckle part body 121 so that the strap does not slip out of the male buckle part body 121.
[0026] Furthermore, the actuating section 1241 can have a luminescent element. In particular, the luminescent element is a fluorescent element made of a fluorescent material and covers the surface of the actuating section 1241. In other embodiments, the luminescent element can be an LED light, but this is not the only possible application covered by the present disclosure. This improves the visibility of the actuating section 1241 at night, and the buckle device 100 can be advantageously operated by the user at night.
[0027] Fig. Figure 6 is a three-dimensional schematic view of a buckle device 200 according to the second embodiment of the present disclosure. Fig. Figure 7 is a top view of the male buckle part 220 decoupled from the female buckle part 210 according to the second embodiment in Fig. 6. Fig. Figure 8 is a three-dimensional schematic view of the female buckle part 210 according to the second embodiment in Fig. 6. How Fig. 6, Fig. 7 to Fig. As shown in Figure 8, the buckle device 200 has a female buckle part 210 and a male buckle part 220. In the second embodiment, the structure and configuration of the female buckle part 210 and the male buckle part 220 are similar to the female buckle part 110 and male buckle part 120 of the first embodiment, which is why they are not described in more detail here. In particular, an insertion hole 211 of the female buckle part 210 is a V-shaped space that corresponds to the shape of two engagement sections 222 of the male buckle part 220. More precisely, when the engagement sections 222 are inserted into the insertion hole 211 and are thus engaged, a portion of an elastic connecting element 223 of the male buckle part 220 is exposed from the insertion hole 211, thereby fully exposing a connecting cord 2242 from the insertion hole 211.This reduces the weight and manufacturing costs of the female buckle part 210, and it is advantageous for the user to pull on an actuating section 2241 to improve the ease of actuating the buckle device 200.

Each of the buckle devices 300, 400, 500 can be the buckle device 100 of the first embodiment or the buckle device 200 of the second embodiment, and the buckle devices 300, 400, 500 are not described in detail herein. As in Fig. 9, Fig. 10 to Fig. As shown in Figure 11, the buckle devices 300, 400, 500 of the present disclosure can be applied in different ways to different fields.
[0029] During mountain hikes by a user, according to Fig. 9. The user further secures two shoulder straps of the backpack 10 through the buckle device 300 to prevent the backpack 10 from falling off while hiking. With the buckle device 300 of the present disclosure, even if the user is wearing cold-resistant gloves that make it inconvenient to operate the buckle device 300, the user can still release the buckle device 300 by means of an actuating element of the buckle device 300 in order to easily remove the backpack 10.
[0030] According to Fig. 10 is often a detachable connecting device of protective equipment such as the life jacket 20, located on top of the user's shoulder and is inconvenient for the user to remove. With the buckle device 400 of the present disclosure, the user can pull on an actuating section to release the buckle device 400, the user can conveniently remove the life jacket 20 themselves, and comfort is improved.
[0031] As in Fig.As shown in Figure 11, if the user is wearing gloves 30, the thickness of the gloves 30 can restrict the user's hand mobility during operation, making it inconvenient for the user to operate the adjustment straps on the gloves 30. With the buckle device 500 of this disclosure, the user can pull directly on an actuating section of the buckle device 500 to quickly release the buckle device 500 arranged on the adjustment strap, thereby allowing the user to conveniently remove the gloves 30.
