Description

Buckle

The present invention relates to the field of infant carriers, and in particular to a buckle.

With the continuous development of economy and the continuous progress of science and technology, people's lives are provided with extremely rich material consumer goods, and baby carriers are one of the many material consumer goods.

As we all know, braided straps are indispensable in infant carriers; in order to allow different braided straps to be assembled and disassembled at any time, buckles are indispensable.

At present, the traditional buckle includes 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 located either on the front of the male buckle or the female buckle or on the back of the male buckle or the female buckle, so that the button is in a very conspicuous position, so that people can quickly find the button and press the button. However, because the button is in a very conspicuous position, the baby riding in the baby carrier can easily find the button and touch the button subconsciously, thereby increasing the risk of accidental release. At the same time, the traditional buckle needs to act on the button with a large force when releasing, which increases the difficulty of the release operation. Secondly, the button is placed on the front and back surfaces of the male or female buckle, which increases the chance of scratching with external objects, thereby increasing the risk of accidental unlocking; of course, there are buckles on the market with highly concealed buttons, but such buckles have complex structures and inconvenient unlocking operations.

In order to explain the technical content and structural features of the present invention in detail, the following is a further explanation in combination with the implementation method and the accompanying drawings.

Please refer to Figures 1 to 6. The buckle 100 of the present invention includes a first buckle 1, a second buckle 2, a release operating member 3 and two elastic members 6. The second buckle 2 has a locking portion 4, and the first buckle 1 has a mating locking portion 5 for cooperating with the locking portion 4. The first buckle 1 and the second buckle 2 are matingly inserted along the mating direction (as indicated by the arrow P in Figure 6), so that the locking portion 4 is locked with the mating locking portion 5 along the side direction of the buckle 100. In this embodiment, the first buckle 1 can be a male buckle, and the second buckle 2 can be a female buckle. Of course, according to actual needs, in another embodiment, the first buckle can be a female buckle and the second buckle can be a male buckle, so it is not limited to this. The release operating member 3 is embedded in the second fastener 2 and is linked to the locking portion 4. The release operating member 3 is also exposed on the side wall of the second fastener 2 and can slide relative to the second fastener 2 along the side direction. It is worth noting that the side direction here refers to the direction indicated by the arrows M1 and M2 in Figure 5. When the release operating member 3 slides along the side direction, the locking portion 4 is driven to move away from the mating locking portion 5 along the side direction of the second fastener 2 and is released from the mating locking portion 5. The sliding direction of the release operating member 3 is the same as or opposite to the release direction in which the release operating member 3 drives the locking portion 4, so that the force applied by the user to the release operating member 3 can be fully transmitted to the locking portion 4 along its sliding direction, and the locking portion 4 receives all the force of the release operating member 3 for release, thereby avoiding the force applied by the user from being dispersed in other directions, thereby making the user's release operation more labor-saving and the release more convenient. The mating lock portion 5 is located on the front side of the first fastener 1, and the second fastener 2 is provided with a mating hole 21 for the mating lock portion 5 to pass through, and the mating direction of the first fastener 1 and the second fastener 2 (as indicated by the arrow P in FIG. 6 ) and the sliding direction of the unlocking operating member 3 (as indicated by the arrows M1 and M2 in FIG. 5 ) are intersected, so that the thickness of the fastener 100 in the mating direction can be reduced during the manufacturing process, thereby making reasonable use of the internal space of the fastener 100 and making it more compact. More specifically, as follows: please refer to Figures 3 to 6, the locking part 4 is an elastic structure, and the release operating member 3 drives the locking part 4 to elastically deform away from the mating locking part 5 along the side direction of the second fastener 2, so that the locking part 4 and the mating locking part 5 are released. Specifically, the locking portion 4 includes a first locking portion 4a located outside one side of the mating locking portion and a second locking portion 4b located outside the other side of the mating locking portion 5. The first locking portion 4a and the second locking portion 4b embrace the mating locking portion 5 along the side direction. The release operating member 3 includes a first release operating member 3a arranged on the same side as the first locking portion 4a and a second release operating member 3b arranged on the same side as the second locking portion 4b. The first release operating member 3a is pushed and matched with the second locking portion 4b, and the second release operating member 3b is pushed and matched with the first locking portion 4a. The first release operating member 3a drives the second locking portion 4b to perform elastic deformation away from the mating lock portion 5 and the second release operating member 3b drives the first locking portion 4a to perform elastic deformation away from the mating lock portion 5, so that the first locking portion 4a and the second locking portion 4b release the locking of the mating lock portion 5. Therefore, the mutual cooperation between the first release operating member 3a, the second release operating member 3b, the first locking portion 4a and the second locking portion 4b makes the locking and unlocking processes more reliable. Of course, in other embodiments, the release operating member and the locking portion are one, three or four, so it is not limited to this.

Referring to FIGS. 3 to 6 , the first locking portion 4a includes a first spring arm 41a for being linked with the second unlocking operating member 3b and a first lock head 42a for locking with the mating lock portion 5. The first lock head 42a is connected to the first spring arm 41a. The first spring arm 41a always has a tendency to drive the first lock head 42a to lock with the mating lock portion 5 along the side direction. The second unlocking operating member 3b is used to drive the first spring arm 41a to perform elastic deformation away from the mating lock portion 5, so that the first lock head 42a and the mating lock portion 5 are locked. The second locking portion 4b includes a second spring arm 41b which is linked to the first unlocking operating member 3a and a second lock head 42b which is locked with the mating lock portion 5. The second lock head 42b is connected to the second spring arm 41b, and the second spring arm 41b always has a tendency to drive the second lock head 42b to lock with the mating lock portion 5 along the lateral direction. The first unlocking operating member 3a is used to drive the second spring arm 41b to perform elastic deformation away from the mating lock portion 5, so that the second lock head 42b is released from the mating lock portion 5. Preferably, in this embodiment, the second release operating member 3b is used to push the first elastic arm 41a to perform elastic deformation away from the mating lock portion 5, and the first release operating member 3a is used to push the second elastic arm 41b to perform elastic deformation away from the mating lock portion 5. At this time, the force applied by the user to the release operating member 3 is a thrust. Of course, in other embodiments, the first release operating member can be used to pull the first elastic arm to perform elastic deformation away from the mating lock portion, and the second release operating member can be used to pull the second elastic arm to perform elastic deformation away from the mating lock portion. At this time, the force applied by the user to the release operating member is a pulling force, so it is not limited thereto. It is understandable that the pulling force or pushing force exerted by the user on the unlocking operating member can drive the first elastic arm and the second elastic arm to move away from the mating lock.

Please refer to Figures 3 to 6. The first release operating member 3a has a first push portion 31a protruding along the lateral direction. The free end of the second elastic arm 41b is provided with a second matching push portion 43b linked to the first push portion 31a. When the first release operating member 3a slides along the lateral direction, the first push portion 31a pushes the second matching push portion 43b to make the second elastic arm 41b elastically deform away from the mating lock portion 5, so that the second lock head 42b is in contact with the mating lock. The second release operating member 3b has a second pushing portion 31b protruding along the lateral direction, and the free end of the first elastic arm 41a is provided with a first matching pushing portion 43a linked to the second pushing portion 31b. When the second release operating member 3b slides along the lateral direction, the second pushing portion 31b pushes the first matching pushing portion 43a to elastically deform the first elastic arm 41a away from the mating lock portion 5, thereby releasing the first lock head 42a from the mating lock portion 5. Preferably, the first supporting part 43a is aligned with the second supporting part 31b along the lateral direction; the second supporting part 43b is aligned with the first supporting part 31a along the lateral direction, so that the pushing of the release operating member 3 is more accurate, and the release operation is more labor-saving.

Referring to FIGS. 3 to 6 , the inner side wall of the first spring arm 41a protrudes along the side direction to form a first lock head 42a, and the first top portion 43a is adjacent to the first lock head 42a; the inner side wall of the second spring arm 41b protrudes along the side direction to form a second lock head 42b, and the second top portion 43b is adjacent to the second lock head 42b. Therefore, when the first pushing portion 31a pushes the second supporting portion 43b and the second pushing portion 31b pushes the first supporting portion 43a, the first elastic arm 41a and the second elastic arm 41b are elastically deformed away from the mating lock portion 5, so that the first lock head 42a and the second lock head 42b are released from the mating lock portion 5 more quickly. Preferably, the first lock head 42a and the first supporting top portion 43a are arranged in sequence from the fixed end of the first spring arm 41a to the free end; the second lock head 42b and the second supporting top portion 43b are arranged in sequence from the fixed end of the second spring arm 41b to the free end, so the first supporting top portion 43a and the second supporting top portion 43b are both located on the free end, so that the force transmitted from the first pushing portion 31a to the second supporting top portion 43b can be as labor-saving as possible, and the second spring arm 41b can be deformed with a relatively small force. The same is true for the second pushing portion 31b, so it is not elaborated. Specifically, the first supporting top portion 43a is arranged one higher than the other in the vertical direction of the buckle 100 (i.e., in the direction of arrow P in FIG. 6 ), and the first pushing portion 31a is arranged one higher than the other in the vertical direction of the buckle 100, and the second pushing portion 31b is arranged one higher than the other in the vertical direction of the buckle 100, so that the pushing motions of the first pushing portion 31a and the second pushing portion 31b are performed simultaneously at different heights, so that the sliding motions of the two along the lateral direction do not conflict and are more reliable, thereby ensuring the reliability of the unlocking. For example, in this embodiment, the height of the second pushing portion 31b and the first supporting top portion 43a is higher than the height of the first pushing portion 31a and the second supporting top portion 43b, but the present invention is not limited thereto. Preferably, the first top portion 43a is staggered with the second top portion 43b along the lateral direction, and the first push portion 31a is staggered with the second push portion 31b along the lateral direction, thereby reducing the proportion of the first top portion 43a and the second top portion 43b in the upper and lower spaces. Staggering the two is more conducive to the spatial arrangement after the two are staggered. For example, in this embodiment, the first push portion 31a and the second top portion 43b are positioned ahead of the second push portion 31b and the first top portion 43a in the protruding direction (such as the direction indicated by the arrow Q in Figure 5) perpendicular to the insertion direction and the lateral direction, but not limited to this.

It is understood that in other embodiments, when only one of the locking parts is locked with the mating locking part from one side, the locking part is driven by a release operating member to elastically deform the locking part along the side direction away from the mating locking part, so that the locking part and the mating locking part are released. Preferably, the release operating member and the locking part are arranged on opposite sides. That is, the locking part is located on one side of the mating lock part, and the release operating member is located on the other side opposite to the mating lock part, so as to achieve the purpose of the release operating member pushing and releasing the locking part on the opposite side; of course, according to actual needs, the release operating member can also be arranged on the same side as the locking part, so as to achieve the purpose of the release operating member pulling and releasing the locking part on the same side.

Please refer to Figures 3 to 6. The mating lock portion 5 has a push structure 51 and a matching lock structure 52. During the mating process between the first fastener 1 and the second fastener 2, the push structure 51 pushes the lock head (i.e., the first lock head 42a and the second lock head 42b) to drive the spring arm (i.e., the first spring arm 41a and the second spring arm 41b) to generate elastic deformation so that the lock head slides to a position locked with the matching lock structure 52. The release operating member 3 is used to drive the spring arm to perform elastic deformation away from the matching lock structure 52 so that the lock head and the matching lock structure 52 are released. Preferably, the end of the push structure 51 has a first inclined structure 511 inclined to the insertion direction, and each lock head has a second inclined structure 421 matching the first inclined structure 511; during the insertion process of the first fastener 1 and the second fastener 2, the first inclined structure 511 pushes the second inclined structure 421 to make the push structure 51 pass over the lock head and slide to the position where the matching lock structure 52 is locked with the lock head. For example, the matching lock structure 52 is an annular groove, and the lock head is used to be inserted into the annular groove.

Please refer to Figures 3 to 5. The elastic member 6 is disposed between the release operating member 3 and the second fastener 2. The elastic member 6 always has a tendency to drive the release operating member 3 to slide in a direction away from the locking portion 4, so that the release operating member 3 can be reset after the release operating member 3 is released through the elasticity of the elastic member 6. Specifically, the second fastener 2 is provided with two C-shaped stoppers 24 for the elastic member 6 to be placed. The two elastic members 6 are respectively disposed between the first release operating member 3a and the second fastener 2 and between the second release operating member 3b and the second fastener 2.

Please refer to Figures 3 to 5. The first release operating member 3a and the second release operating member 3b of the release operating member 3 are respectively provided with a limit protrusion 33. The second buckle 2 has two limit blocks 25 that cooperate with the limit protrusion 33. The second buckle 2 prevents the first release operating member 3a and the second release operating member 3b of the release operating member 3 from sliding off from the second buckle 2 under the action of the limit blocks 25 and the limit protrusion 33.

Please refer to Figures 3 to 5, the locking part 4 is connected to the second fastener 2 by snapping. Preferably, the locking part 4 is connected to the second fastener 2 in a detachable snap-fit connection, so the locking part 4 or the second fastener 2 can be replaced if either is damaged. In addition, the manufacturing process of the fastener 100 of the present invention is simpler. Specifically, the locking part 4 also includes a snap-fit support frame 44, and the second fastener 2 is provided with two clips 22 snap-fitted to the snap-fit support frame 44. The snap-fit support frame 44 is embedded in the clips 22, and the snap-fit support frame 44 is fixedly connected to the fixed end of the elastic arm. Therefore, the locking part 4 is snap-fitted to the second fastener 2 by the snap-fit fixation between the snap-fit support frame 44 and the two clips 22. The two clamping strips 22 are arranged opposite to each other at intervals, and the clamping support frame 44 is embedded between the two clamping strips 22. Each clamping strip 22 has an upper limit stop portion 221 and a lower limit stop portion 222 for limiting the clamping support frame 44. The clamping support frame 44 is located between the upper limit stop portion 221 and the lower limit stop portion 222. The upper limit stop portion 221 and the lower limit stop portion 222 prevent the locking portion 4 from sliding out of the second fastener 2 along the protruding direction. Of course, it is understandable that the number of clamping strips can be 3 or more, so it is not limited to this. Preferably, the clamping support frame 44 is provided with a step structure 441, and the step structure 441 is clamped with the lower limit stop portion 222. Therefore, by means of the step structure 441 and the lower limit stop portion 222, the locking portion 4 is not easily disengaged from the lower limit stop portion 222, and the engaging support frame 44 can also be embedded between the two lower limit stop portions 222, so as to reasonably utilize the space in the second fastener 2. Preferably, the interval between the two clamping strips 22 forms an escape space 9 for the elastic arm to move. By means of the escape space 9, the elastic arm can extend out of the escape space 9 along the protruding direction, so as to be able to perform elastic deformation movement.

Please refer to Figures 3 to 6. The 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 disposed on the first fastener 1, and the second magnetic structure 8 is disposed on the second fastener 2. The first magnetic structure 7 and the second magnetic structure 8 are magnetically attracted to each other during the insertion process of the first fastener 1 and the second fastener 2. On the one hand, the first fastener 1 and the second fastener 2 are fastened together more quickly. On the other hand, even if the locking portion 4 and the mating locking portion 4 are not locked, the locking portion 4 and the mating locking portion 4 are locked. 5, the first fastener 1 and the second fastener 2 are also kept in a connected state due to the mutual magnetic attraction of the first magnetic structure 7 and the second magnetic structure 8, thereby preventing accidental unlocking and ensuring the safety of the 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 designed to magnetically repel each other during the insertion process of the first fastener 1 and the second fastener 2, so as to make the unlocking more convenient, so it is not limited to this. Specifically, the first fastener 1 is provided with a first embedding cavity 11, the second fastener 2 is provided with a second embedding cavity 23, 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 23; preferably, the first embedding cavity 11 is aligned with the second embedding cavity 23 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 23 is directly opposite to the space between the first lock head 42a and the second lock head 42b along the insertion direction, as shown in FIG6, so that the buckle 100 of the present invention has reasonable space utilization and a compact size.

Please refer to Figures 5 and 6 to illustrate the working principle of the buckle 100 of the present invention: during the unlocking operation, the user presses the first unlocking operating member 3a and the second unlocking operating member 3b at the same time, the first pushing portion 31a of the first unlocking operating member 3a pushes the second supporting portion 43b of the second locking portion 4b, and the second pushing portion 31b of the second unlocking operating member 3b pushes the first supporting portion 43b of the first locking portion 4a. 43a, thereby driving the first elastic arm 41a and the second elastic arm 41b to elastically deform away from the mating lock portion 5 along the side direction of the second fastener 2, so that the first lock head 42a and the second lock head 42b simultaneously release the locking of the mating lock portion 5. At this time, the buckle 100 is in a releasable state. As long as the first fastener 1 and the second fastener 2 are pulled apart from each other, the buckle 100 is completely released. After releasing the first release operating member 3a and the second release operating member 3b, the elastic member 6 drives the first release operating member 3a and the second release operating member 3b to reset. When the first fastener 1 and the second fastener 2 need to be locked, the mating lock part 5 is aligned with the mating hole 21 and inserted, and the pushing structure 51 pushes the first lock head 42a and the second lock head 42b at the same time to drive the first spring arm 41a and the second spring arm 41b to deform, so that the first lock head 42a and the second lock head 42b slide under the action of the first spring arm 41a and the second spring arm 41b to the position locked with the mating lock structure 52.

Referring to FIGS. 7 to 10 , the buckle 100 ′ of the present invention comprises a first buckle 1, a second buckle 2 ′, a release operating member 3, two elastic members 6, a first magnetic structure 7 and a second magnetic structure 8. The structures of the first buckle 1, the release operating member 3, the elastic member 6, the first magnetic structure 7 and the second magnetic structure 8 of this embodiment are similar to those of the first embodiment, and are not described in detail for the sake of brevity. The second buckle 2 ′ has a locking portion 4 ′, and the locking portion 4 ′ comprises a first locking portion 4a ′ located outside one side of the first buckle 1 that is opposite to the mating locking portion 5 and a second magnetic structure 8 located at the first buckle 1. For the second locking part 4b' on the other side of the mating lock part, the first locking part 4a' and the second locking part 4b' are engaged with the mating lock part 5 along the side direction (as indicated by arrows M1 and M2 in Figures 9 and 10), the first locking part 4a' is arranged on the same side as the first release operating part 3a of the release operating part 3 and is pushed and matched with the second release operating part 3b of the release operating part 3, and the second locking part 4b' is arranged on the same side as the second release operating part 3b of the release operating part 3 and is pushed and matched with the first release operating part 3a of the release operating part 3.

Specifically, the first locking portion 4a' includes a first rotating arm 41a' and a first lock head 42a' for locking with the mating locking portion 5. The first rotating arm 41a' is pivotally connected to the second fastener 2' through the first pivot portion 411a'. The first rotating arm 41a' is provided with a first matching top portion 43a' which is linked to the second pushing portion 31b of the second release operating member 3b. The first matching top portion 43a' is aligned with the second pushing portion 31b along the lateral direction. The first lock head 42a' is connected to the first rotating arm 41a' and protrudes from the inner side wall of the first rotating arm 41a' along the lateral direction. The second locking portion 4b’ includes a second rotating arm 41b’ and a second lock head 42b’ for locking with the mating locking portion 5. The second rotating arm 41b’ is pivotally connected to the second fastener 2’ via the second pivot portion 411b’. The second rotating arm 41b’ is provided with a second matching top portion 43b’ which is linked to the first pushing portion 31a of the first release operating member 3a. The second matching top portion 43b’ is aligned with the first pushing portion 31a along the lateral direction. The second lock head 42b’ is connected to the second rotating arm 41b’ and protrudes from the inner side wall of the second rotating arm 41b’ along the lateral direction. In this embodiment, the first top portion 43a' is arranged one higher than the second top portion 43b' in the vertical direction and staggered with the second top portion 43b' along the side direction, so that the movement does not conflict and is more reliable, and is conducive to spatial layout. Preferably, in this embodiment, the first pivot portion 411a' and the second pivot portion 411b' can be slotted structures for the pivot axis of the second fastener 2' to rotate.

In addition, the first locking portion 4a' further includes a first reset member 44a', and the second locking portion 4b' further includes a second reset member 44b'. The first reset member 44a' is disposed between the first rotating arm 41a' and the second fastener 2' and always has a tendency to drive the first rotating arm 41a' to rotate so that the first lock head 42a' is mutually locked with the mating lock portion 5 along the lateral direction. The second reset member 44b' is disposed between the second rotating arm 41b' and the second fastener 2' and always has a tendency to drive the second rotating arm 41b' to rotate so that the second lock head 42b' is mutually locked with the mating lock portion 5 along the lateral direction. Preferably, in this embodiment, the first reset member 44a' and the second reset member 44b' may be compression springs, but the present invention is not limited thereto. For example, in another embodiment, the first reset member and the second reset member may be torsion springs.

During the unlocking operation, the user presses the first unlocking operating member 3a and the second unlocking operating member 3b of the unlocking operating member 3 at the same time, the first pushing portion 31a of the first unlocking operating member 3a pushes the second supporting pushing portion 43b' of the second locking portion 4b', and the second pushing portion 31b of the second unlocking operating member 3b pushes the first supporting pushing portion 43a' of the first locking portion 4a', thereby driving the first rotating arm 41a' and the second rotating arm 41a' to move. b' rotates and compresses the first reset member 44a' and the second reset member 44b', so that the first reset member 44a' and the second reset member 44b' are elastically deformed, so that the first lock head 42a' and the second lock head 42b' are simultaneously released from the mating lock portion 5. At this time, the buckle 100' is in a releasable state. As long as the first buckle 1 and the second buckle 2' are pulled apart from each other, the buckle 100' is completely released. After the first release operating member 3a and the second release operating member 3b are released, the elastic member 6 drives the first release operating member 3a and the second release operating member 3b to reset. When the first fastener 1 and the second fastener 2' need to be locked, the mating lock part 5 is aligned with the mating hole of the second fastener 2' and inserted, and the pushing structure 51 pushes the first lock head 42a' and the second lock head 42b' at the same time, so as to drive the first rotating arm 41a' and the second rotating arm 41b' to rotate and compress the first reset member 44a' and the second reset member 44b', so that the first reset member 44a' and the second reset member 44b' produce elastic deformation, so that the pushing structure 51 passes over the first lock head 42a' and the second lock head 42b', so that the first lock head 42a' and the second lock head 42b' slide under the action of the first reset member 44a' and the second reset member 44b' to a position locked with the mating lock structure 52.

It is understood that in other embodiments, when only one locking part is locked with the mating locking part from one side, the locking part is driven by a release operating member to rotate the rotating arm to compress the reset member to produce elastic deformation, so that the lock head and the mating locking part are released. Preferably, the release operating member and the locking part are arranged on opposite sides, that is, the lock The fixed part is located on one side of the mating lock part, and the unlocking operating part is located on the other side opposite to the mating lock part, so as to achieve the purpose of the unlocking operating part pushing the locking part on the opposite side to rotate and release; of course, according to actual needs, the unlocking operating part can also be arranged on the same side as the locking part, so as to achieve the purpose of the unlocking operating part pulling the locking part on the same side to rotate and release.
