Description

[0001] This application is a divisional application of the invention patent application of Mingmen Switzerland Co., Ltd. (the application date is April 30, 2019, the application number is 201910370875.3, and the invention name is "Side-release buckle"). Technical Field

[0005] At present, for traditional buckles, they include a male buckle, a female buckle and a button. The male buckle and the female buckle are buckled and fixed to each other. The button is used to release the male buckle and the female buckle from each other. The button is either located on the front of the male buckle or the female buckle, or on the back of the male buckle or the female buckle, and the exposed area of ​​the button is large, so that the button is in a very conspicuous position, so that people can quickly find the button, so as to facilitate the pressing operation of the button; however, because the button is in a very conspicuous position, it is very easy for infants and young children riding in infant carriers to find the button and touch the button subconsciously, thereby increasing the risk of accidental release. At the same time, this type of button can release the buckle as long as a pressure is applied to the button, and because the button is in a conspicuous position with a large area, the chance of the button being accidentally scratched by external objects is increased, thereby further increasing the risk of accidental release.

[0046] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0047] See also Figures 1 to 4 The side-release buckle 100 of the present invention comprises a male buckle 1, a female buckle 2, a release operating member 3 and an elastic member 4. The female buckle 2 has a locking portion 5, and the male buckle 1 has a mating locking portion 6 for mating with the locking portion 5; the male buckle 1 and the female buckle 2 are mated in a direction close to each other (such as Figure 8 The locking portion 5 is locked with the mating locking portion 6 by pressing the locking portion 5 in the direction indicated by the arrow P in the middle; of course, according to actual needs, the male buckle 1 can have a locking portion 5, and correspondingly, the female buckle 2 can have a mating locking portion 6 for cooperating with the locking portion 5, so that the locking of the male buckle 1 and the female buckle 2 can be achieved, so it is not limited to this. The unlocking operating member 3 is embedded in the female buckle 2 and arranged in conjunction with the locking portion 5. The unlocking operating member 3 is also exposed on the side wall of the female buckle 2 and slides laterally along the female buckle 2. It is worth noting that the lateral direction here refers to the thickness direction of the side wall where the unlocking operating member is located (for example Figure 8Of course, in other embodiments, the lateral direction may also refer to the length direction of the side wall where the unlocking operating member is located. The unlocking operating member 3 selectively links the locking portion 5 and releases the mating locking portion 6 during the lateral sliding process. The elastic member 4 is disposed between the unlocking operating member 3 and the locking portion 5. The elastic member 4 always has the function of driving the unlocking operating member 3 in a direction away from the locking portion 5 (such as Figure 8 The elastic member 4 can be used to prevent the release member 3 from sliding along the direction indicated by M1 in the figure, so that the release member 3 can be reset after being released by the elastic member 4. Of course, according to actual needs, the elastic member 4 can be arranged between the release member 3 and the female buckle 2, and the purpose of resetting the release member 3 by the elastic member 4 can also be achieved, so it is not limited to this. Specifically, the release member 3 moves in the direction close to the locking portion 5 (such as Figure 8 The locking part 5 and the mating lock part 6 are released in the process of sliding sideways in the direction indicated by M2 in the figure, and the unlocking operation member 3 is reset in the process of sliding sideways in the direction away from the locking part 5. The female buckle 2 is provided with a mating hole 212 for the mating lock part 6 to pass through. The mating part 6 is located at the front of the male buckle 1, and the mating direction of the male buckle 1 and the female buckle 2 (as shown in FIG. Figure 8 The direction indicated by the arrow P in the middle) and the sliding direction of the unlocking operating member 3 (as Figure 8 The directions indicated by the arrows M1 and M2 in the middle are staggered, so that the thickness of the buckle 100 in the insertion direction can be reduced during the manufacturing process, so that the internal space of the buckle 100 is reasonably utilized and more delicate, more specifically, as follows:

[0048] See also Figure 3 and Figure 4 The unlocking operating member 3 is convexly arranged on the side wall of the female buckle 2 to facilitate the unlocking operation. Of course, according to the actual needs, the unlocking operating member 3 is inserted into the female buckle 2, and its top is flush with the side wall of the female buckle 2, so as to facilitate the hiding of the unlocking operating member 3, but it is not limited to this. The unlocking operating member 3 includes a unlocking body 33 and an operating portion 34 extending from the unlocking body 33 and passing through the side wall of the female buckle 2. A limiting boss 35 is formed at the intersection of the operating portion 34 and the unlocking body 33. The limiting boss 35 selectively contacts the inner side wall of the female buckle 2. With the help of the limiting boss 35, the unlocking operating member 3 will not fall off from the side wall of the female buckle 2 during the resetting process.

[0049] See also Figures 3 to 6The locking part 5 is an elastic structure, and the unlocking operation member 3 links the locking part 5 to elastically deform along the lateral direction of the female buckle 2 to release the lock with the mating lock part 6. Specifically, the locking part 5 includes an elastic arm 51 and a lock head 52 for locking with the mating lock part 6, the lock head 52 is connected to the elastic arm 51, and the elastic arm 51 always has a tendency to drive the lock head 52 and the mating lock part 6 to lock with each other; the unlocking operation member 3 selectively links the elastic arm 51 to elastically deform so that the lock head 52 and the mating lock part 6 are released. Specifically, the unlocking operation member 3 has a linkage inclined surface 31 inclined relative to the sliding direction of the unlocking operation member 3, and the linkage inclined surface 31 selectively links the elastic arm 51 to elastically deform during the lateral sliding process of the unlocking operation member 3. The locking portion 5 further includes a linkage column 53 connected to the elastic arm 51, and the linkage slope 31 extends toward the linkage column 53 and cooperates with the linkage column 53. The linkage slope 31 pushes the linkage column 53 and drives the elastic arm 51 to elastically deform during the unlocking sliding of the unlocking operating member 3. For example, the unlocking operating member 3 has a linkage rib 32 extending toward the linkage column 53 and abutting against the linkage column 53, and the linkage slope 31 is formed on the side wall of the linkage rib 32 abutting against the linkage column 53, and the side wall of the linkage column 53 is pressed and matched with the linkage slope 31 of the linkage rib 32. Of course, in other embodiments, the lock release operating member 3 is provided with a linkage rib that is slidably matched with the linkage column 53, and the linkage rib is provided with a linkage groove for the linkage column 53 to pass through and slide, and the linkage slope 31 is formed on the side wall of the linkage groove. In the process of sliding along the side of the lock release operating member 3 close to the locking portion 5, the linkage column 53 is pushed by the linkage groove to drive the elastic arm 51 to elastically deform, and the lock release between the locking portion 5 and the mating lock portion 6 can also be achieved, so the existence of the linkage slope 31 is not limited to this. More specifically, the linkage slope 31 gradually opens relative to the center line C of the lock release operating member 3 along the sliding direction of the lock release operating member 3 sliding away from the locking portion 5, so that in the process of the linkage slope 31 pushing the linkage column 53, the linkage column 53 drives the elastic arm 51 to elastically deform with the opening of the linkage slope 31, so that the lock head 52 and the mating lock portion 6 can be released. It is worth noting that the linkage rib 32 and the linkage inclined surface 31 are disposed on the unlocking body 33 .

[0050] See also Figure 3 , Figure 4 and Figure 6The plug-in lock portion 6 includes a matching lock structure 62 and a pushing structure 61 arranged in sequence along the plug-in direction P1 away from the male buckle 1. The pushing structure 61 pushes the lock head 52 to drive the elastic arm 51 to produce elastic deformation during the plug-in process, so that the lock head 52 slides to a position locked with the matching lock structure 62. The release operating member 3 selectively links the elastic arm 51 to make elastic deformation so that the lock head 52 is separated from the lock with the matching lock structure 62; preferably, the end of the pushing structure 61 has an inclination relative to the plug-in direction P1. The first inclined structure 611 is inclined, and the lock head 52 has a second inclined structure 521 that matches the first inclined structure 611. Therefore, during the insertion process, the first inclined structure 611 pushes the second inclined structure 521 to make the pushing structure 61 pass over the lock head 52 and slide to the position where the matching lock structure 62 and the lock head 52 are locked; for example, the lock head 52 is a hook-shaped structure, and the matching lock structure 62 is a hook groove, so that the locking between the lock head 52 and the matching lock structure 62 is more reliable, but not limited to this. Preferably, there are two elastic arms 51 and they are arranged in an embracing manner to the matching lock part 6, each elastic arm 51 is connected to the lock head 52, and the lock head 52 is arranged to embrace the matching lock structure 62. Correspondingly, each elastic arm is connected to a linkage column 53, and the linkage ribs on the unlocking operating member are symmetrically distributed along the center line of the unlocking operating member, so that the two linkage inclined surfaces 31 are also symmetrically distributed along the center line C of the unlocking operating member 3.

[0051] See also Figures 3 to 5The female buckle 2 includes a first cover body 21 and a second cover body 22, which are detachably spliced, and the first cover body 21 and the second cover body 22 together enclose a receiving cavity 23 for the locking portion 5 to be built in. Preferably, a protective plate 211 is extended from the bottom of the first cover body 21 along the sliding direction of the release operating member 3 away from the locking portion 5, and the release operating member 3 overlaps with the protective plate 211 in the insertion direction P. With the help of the protective plate 211, it is prevented that the infant presses the release operating member 3 in the insertion direction P, and the release operating member 3 is prevented from breaking. At the same time, with the support of the release operating member 3 by the protective plate 211, the sliding of the release operating member 3 is more stable and reliable. The protective plate 211 is flush with the release operating member 3 in the sliding direction M1 of the release operating member 3 away from the locking portion 5, which saves the material of the protective plate 211 and makes the appearance of the lateral release buckle 100 more beautiful and simple. The middle part of the protection plate 211 has a notch 211a that is recessed toward the locking portion 5, so that when the back of the side-release buckle 100 faces the user, the user can recognize the position of the release operating member 3 at a glance, so that the user can easily recognize the release operating member 3 in the direction facing or facing away from the side-release buckle 100. Specifically, the second cover 22 has an embedded arm 221 embedded in the first cover 21, and the first cover 21 has an embedded cavity for the embedded arm 221 to be embedded. When the embedded arm 221 is embedded in the embedded cavity, the first cover 21 is spliced ​​with the second cover 22 to form a receiving cavity 23. Preferably, the locking portion 5 and the embedded arm 221 are detachably connected. For example, the locking portion 5 has a locking hole 24a, and the embedded arm 221 has a locking column 24b that is engaged with the locking hole 24a, and the locking column 24b and the locking hole 24a are mutually engaged to realize the detachable connection between the locking portion 5 and the embedded arm 221. Of course, according to the actual needs, the embedded arm 221 has a locking hole 24a, and the locking portion 5 has a locking column 24b that is engaged with the locking hole 24a, which can also realize the detachable connection between the locking portion 5 and the embedded arm 221, so it is not limited to this. With the second cover 22 and the locking portion 5 being detachably connected, the first cover 21 and the second cover 22 are detachably connected, and the unlocking operating member 3 can be first assembled with the locking portion 5, and the locking portion 5 is then assembled with the second cover 22, and the second cover 22 is then assembled with the first cover 21, thereby facilitating the assembly of the female buckle 2 and simplifying the manufacturing process of the female buckle 2. It is worth noting that when the release operating member 3 is assembled with the locking portion 5, the linkage slope 31 needs to contact the linkage column 53. It is understandable that according to actual needs, the first cover 21, the second cover 22, and the locking portion 5 can be made into an integrated structure, so it is not limited to this.

[0052] See also Figures 3 to 5The lateral release buckle 100 of the present invention further includes a first magnetic structure 7 and a second magnetic structure 8. The first magnetic structure 7 is arranged on the male buckle 1, and the second magnetic structure 8 is arranged on the female buckle 2. The first magnetic structure 7 and the second magnetic structure 8 are magnetically attracted to each other during the insertion process of the male buckle 1 and the female buckle 2. On the one hand, the male buckle 1 and the female buckle 2 are fastened together. On the other hand, even if the locking portion 5 and the mating locking portion 6 are disengaged, the first magnetic structure 7 and the second magnetic structure 8 are magnetically attracted to each other and maintain the engagement state, thereby preventing accidental release and ensuring the safety of the lateral release buckle 100 of the present invention. Of course, according to actual needs, the first magnetic structure 7 and the second magnetic structure 8 can be magnetically repelled from each other during the insertion process of the male buckle 1 and the female buckle 2 to make the release more convenient, so it is not limited to this. Specifically, the male buckle 1 is provided with a first embedding cavity 11, the female buckle 2 is provided with a second embedding cavity 25, the first magnetic structure 7 is embedded in the first embedding cavity 11, and the second magnetic structure 8 is embedded in the second embedding cavity 25; preferably, the first embedding cavity 11 is aligned with the second embedding cavity 25 along the insertion direction, so that the adsorption force between the first magnetic structure 7 and the second magnetic structure 8 is stronger, but not limited to this. Specifically, the second embedding cavity 25 is opposite to the space between the two lock heads 52 along the insertion direction P, and the state is shown in FIG. Figure 8 As shown, the side-release buckle 100 of the present invention makes reasonable use of space and has a compact size.

[0053] See also Figure 3 , Figure 4 and Figure 6 In order to improve the safety of preventing accidental release of the side-release buckle 100 of the present invention, both the plug-in lock portion 6 and the female buckle 2 having the locking portion 5 are provided with an escape space 9. When the male buckle 1 and / or the female buckle 2 is pulled, the escape space 9 allows the plug-in lock portion 6 locked with the locking portion 5 to move in an offset direction (such as 1.5) intersecting the insertion direction P. Figure 4 The direction indicated by the arrow M1 is Figure 8The female buckle 2 with the locking portion 5 is provided with a counter-joint portion (not shown in the figure) corresponding to the offset position, and when the counter-joint locking portion 6 is in the offset position, it also resists against the counter-joint portion to prevent the male buckle 1 and the female buckle 2 from being pulled out from each other; of course, according to actual needs, the male buckle 1 with the locking portion 5 can be provided with a counter-joint portion corresponding to the offset position, so it is not limited to this. Specifically, the avoidance space 9 on the plug-in lock portion 6 is an avoidance groove, with the help of the avoidance groove, the plug-in lock portion 6 can smoothly slide to the offset position and resist the mating portion; the side groove wall 9a of the avoidance groove separates the mating lock structure 62 into a first part 621 for locking with the locking portion 5 and a second part 622 for resisting the mating portion along the offset direction M1; preferably, there are two avoidance grooves and they are arranged opposite to each other on the plug-in lock portion 6, that is, there are two avoidance grooves, so that the first part 621 and the second part 622 separated by the side groove wall 12a of the avoidance groove are two each, the two first parts 621 are arranged opposite to each other, and the two second parts 622 are arranged opposite to each other, so that the user does not have to spend too much time observing the plug-in positioning between the plug-in lock portion 6 and the plug-in hole 212 described below during the plug-in process, but the number of second parts 622 on the plug-in lock portion 6 is not limited to this. More specifically, the pushing structure 61 is separated from the avoidance space 9 of the mating locking portion 6 in a direction parallel to the insertion direction P. During the insertion process, the pushing structure 61 pushes the elastic arm 51 to generate elastic deformation, causing the lock head 52 to slide to a position locked with the first portion 621. The unlocking operating member 3 drives the locking portion 5 to undergo elastic deformation and disengage from the lock with the first portion 621.

[0054] See also Figure 4 The avoidance space 9 on the female buckle 2 is an avoidance hole located on the first cover body 21 and communicated with the insertion hole 212. By means of the avoidance hole communicating with the insertion hole 212, the plug-in locking portion 6 can slide to an offset position on the avoidance hole when passing through the insertion hole 212 and then locked with the locking portion 5; and the abutment portion is formed on the first cover body 21. Preferably, the abutment portion is located on the inner surface of the first cover body 21 adjacent to the hole wall 9b of the avoidance hole. Therefore, when the plug-in locking portion 6 slides to the offset position in the avoidance hole, the second portion 622 can quickly abut against the abutment portion, thereby having the advantages of rapid prevention, simple and quick operation, and more time saving.

[0055] Combined with the accompanying drawings, the working principle of the lateral release buckle 100 of the present invention is explained as follows: the operator presses the release operating member 3 sideways, and the linkage inclined surface 31 of the linkage rib 32 pushes the linkage column 53 on the locking portion 5, and then the linkage column 53 drives the elastic arm 51 to perform elastic deformation to release the lock head 52 and the matching lock structure 62. Since the matching lock portion 6 is still resisting against the matching portion at this time, the male buckle 1 and the female buckle 2 cannot be pulled out; therefore, the operator needs to slide the matching lock portion 6 away from the resisting position with the matching portion to allow the male buckle 1 and the female buckle 2 to be pulled out; and since the first magnetic structure 7 and the second magnetic structure 8 are in mutual adsorption, the operator also needs to manually pull the male buckle 1 and the female buckle 2 out at this time.

[0056] Compared with the prior art, since the unlocking operating member 3 of the present invention is embedded in the male buckle 1 or the female buckle 2 where the locking portion 5 is located, the unlocking operating member 3 is also exposed on the side wall of the male buckle 1 or the female buckle 2 where the locking portion 5 is located and slides laterally along the male buckle 1 or the female buckle 2 where the locking portion 5 is located, the operator can only perform the unlocking operation on the unlocking operating member 3 from the side of the buckle 100 of the present invention. Therefore, pressing the buckle 100 of the present invention forward cannot unlock the buckle 100 of the present invention. Compared with traditional buckles, the risk of unlocking caused by scratching from the front by external objects and the risk of accidental unlocking caused by subconscious pressing due to curiosity of infants and young children are prevented. Therefore, the side-release buckle 100 of the present invention has the advantages of not being easily scratched and effectively preventing accidental unlocking.

[0057] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
