Description

Technical Field

[0001] This application relates to the field of backpack technology, and in particular to a buckle, buckle assembly, strap assembly, and backpack. Background Technology

[0002] Backpacks are containers used in people's daily lives to carry items of a certain volume. Backpacks provide convenience for people to travel and carry items. Backpacks on the market usually consist of a bag body and two shoulder straps.

[0003] Because everyone's body shape is different, shoulder straps usually need to be equipped with a buckle to adjust the length of the shoulder strap, thereby adapting to different individual body shapes.

[0004] Please refer to the relevant technologies. Figure 1 and Figure 2 The buckle 100' has a first through hole 101' and a second through hole 102', which are separated by a crossbar 103'. The shoulder strap 200' passes through the first through hole 101', goes around the crossbar 103', and then passes through the second through hole 103'. When the user carries the backpack, under the action of gravity, the pressure bar 104' of the buckle 100' presses the first section 201' of the shoulder strap 200' between the pressure bar 104' and the second section 202' of the shoulder strap 200', thereby locking the shoulder strap 200'.

[0005] During the implementation of this application embodiment, the inventors discovered that: using the above method, the buckle 100' and the shoulder strap 200' are prone to loosening when the user is walking or running, which in turn causes the shoulder strap 200' to slide relative to the crossbar 103', causing the length of the shoulder strap to change.

[0045] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0046] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0047] Please see Figure 3 , Figure 4 and Figure 5 The latch 100 includes a base 1, a holding member 2, and an elastic member 3. The holding member 2 is rotatably disposed on the base 1. One end of the elastic member 3 is connected to the base 1, and the other end of the elastic member 3 is connected to the holding member 2. The base 1 and the holding member 2 are used together to press and fix the item to be locked. The elastic member 3 is configured to drive the holding member 2 to remain in contact with the item to be locked, thereby keeping the latch 100 fixed to the item to be locked.

[0048] The base 1 described above includes a base plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are located at opposite ends of the base plate 11, with the first side plate 12 connected to one end of the base plate 11 and the second side plate 13 connected to the other end of the base plate 11. The base plate 11, the first side plate 12, and the second side plate 13 together form a clamping groove 14, which is configured to receive at least a portion of an item to be locked. The latch 100 is used to clamp and fix the portion of the item to be locked received in the clamping groove 14. The first side plate 12 is provided with a first rotating hole 121, and the second side plate 13 is provided with a second rotating hole 131. One end of the holding member 2 is provided with a first protrusion 21, and the other end of the holding member 2 is provided with a second protrusion 22. The first protrusion 21 is at least partially inserted into the first rotating hole 121 and is rotatably disposed in the first rotating hole 121. The second protrusion 22 is at least partially inserted into the second rotating hole 131 and is rotatably disposed in the second rotating hole 131, so that the holding member 2 can rotate relative to the base 1. An elastic member 3 is sleeved on the first protrusion 21. One end of the elastic member 3 abuts against the base 1, and the other end of the elastic member 3 abuts against the holding member 2, so that the elastic member 3 can output a torque to the holding member 2. This torque can drive the holding member 2 to hold against a portion of the item to be locked located in the clamping groove 14, thereby making the holding member 2 and the base plate 11 jointly clamp the item to be locked, realizing the fixation between the lock 100 and the item to be locked. In this embodiment, by providing a clamping groove 14 on the base 1, the clamping groove 14 is configured to accommodate at least a portion of the item to be locked. By rotating the first protrusion 21 of the pressing member 2 in the first rotating hole 121 and rotating the second protrusion 22 in the second rotating hole 131, the pressing member 2 can rotate relative to the base 1. By sleeved the elastic member 3 on the first protrusion 21, one end of the elastic member 3 abuts against the base 1 and the other end abuts against the pressing member 2, so that the elastic member 3 can drive the pressing member 2 to remain abutting against the item to be locked. Thus, the base 1 and the pressing member 2 jointly press the item to be locked, which helps to improve the stability of the connection between the item to be locked and the latch 100 and reduces the risk of the item to be locked sliding relative to the latch 100.

[0049] It is worth noting that the item to be locked can be a shoulder strap on a backpack, or a strap on clothing or other items. In this application, the shoulder strap on a backpack is used as an example for illustration. The application of the buckle 100 on other items is within the scope of protection of this application.

[0050] It is also worth noting that, since the elastic element 3 keeps the holding member 2 against the shoulder strap in this application, and thus the base plate 11 and the holding member 2 together clamp the shoulder strap, thereby fixing the shoulder strap to the buckle 100, by applying force to the holding member 2 or the base 1, the holding member 2 can overcome the resistance of the elastic element 3 and rotate away from the base plate 11, thereby canceling the fixation of the shoulder strap. At this time, the user can adjust the length of the shoulder strap or pull the shoulder strap out of the clamping groove 14, thereby adjusting the length of the shoulder strap or canceling the connection between the shoulder strap and the buckle 100, so that the user can adjust the shoulder strap to a suitable length according to their own body shape.

[0051] In some embodiments, the first rotating hole 121 and the second rotating hole 131 are coaxial, and the first protrusion 21 and the second protrusion 22 are coaxial, so that the pressing member 2 can rotate relative to the base 1 about the axis H of the second protrusion 22.

[0052] In some embodiments, please refer to Figure 6 The second protruding rod 22 is provided with a guide slope 221, which is located at the end of the second protruding rod 22 away from the first protruding rod 21. From the end of the guide slope 221 near the first protruding rod 21 to the end of the guide slope 221 away from the first protruding rod 21, the guide slope 221 extends obliquely toward the axis H near the second protruding rod 22. With this configuration, during the assembly of the latch 100, the elastic element 3 can be first sleeved on the first protruding rod 21, then the first protruding rod 21 can be inserted into the first rotating hole 121, then the guide slope 221 can be made to abut against the end of the second side wall away from the bottom plate 11, and finally the holding member 2 can be pressed in a direction perpendicular to the bottom plate 11 to snap the second protruding rod 22 into the second rotating hole 131, thus completing the assembly of the latch 100. The assembly steps are simple and convenient, which helps to improve assembly efficiency.

[0053] In some embodiments, please refer to Figure 4 and Figure 5 The elastic element 3 is a torsion spring, which is sleeved on the first protrusion 21. The first side plate 12 is provided with a first abutting groove 123, and the holding member 2 is provided with a second abutting groove 26. One end of the torsion spring is received in the first abutting groove 123, and the other end of the torsion spring is received in the second abutting groove 26, so that the torsion spring can apply a torque to the holding member 2. This torque can keep the holding member 2 abutting against a portion of the shoulder strap located in the clamping groove 14, thereby enabling the base plate 11 and the holding member 2 to hold the shoulder strap, which helps to reduce the risk of the shoulder strap sliding relative to the buckle 100.

[0054] In some embodiments, the elastic member 3 includes a torsion portion 31, a first extension portion 32, and a second extension portion 33. The torsion portion 31 is sleeved on the first protrusion 21. The first extension portion 32 is connected to one end of the torsion portion 31, and the second extension portion 33 is connected to the other end of the torsion portion 31. The first extension portion 32 is at least partially received in the first abutment groove 123 and abuts against one side wall of the first abutment groove 123. The second extension portion 33 is at least partially received in the second abutment groove 26 and abuts against one side wall of the second abutment groove 26, thereby causing the elastic member 3 to apply a torque to the holding member 2, which can keep the holding member 2 abutting against a portion of the shoulder strap in the clamping groove 14.

[0055] In some embodiments, please refer to Figure 4 and Figure 5 The holding member 2 is provided with a receiving groove 28, and a portion of the first protrusion 21 is received in the receiving groove 28, with one end of the first protrusion 21 connected to the bottom of the receiving groove 28. The torsion part 31 is sleeved on the first protrusion 21, and the torsion part 31 is at least partially received in the receiving groove 28. This arrangement allows at least a portion of the elastic member 3 to be received in the receiving groove 28, which helps to reduce the gap between the holding member 2 and the first side plate 12, thereby reducing the size of the latch 100 in the axis H direction of the first protrusion 21, which helps to reduce the space occupied by the latch 100; in addition, this arrangement allows at least a partial concealment of the elastic member 3, which helps to improve the aesthetics of the latch 100.

[0056] In some embodiments, the base plate 11 is provided with a first through hole 111, a second through hole 112, and a holding portion 113. Along a first direction X, the first through hole 111 and the second through hole 112 are spaced apart from each other, and the holding portion 113 is located between the first through hole 111 and the second through hole 112. The first direction X is parallel to the base plate 11 and also parallel to the first side plate 12. One of the first through hole 111 and the second through hole 112 is configured to allow the item to be locked to pass through the clamping groove 14, and the other of the first through hole 111 and the second through hole 112 is configured to allow the item to be locked to pass through the clamping groove 14. The holding portion 113 is configured to hold the item to be locked together with the holding member 2. In other words, when the item to be locked is a shoulder strap from a backpack, the shoulder strap can be inserted into the clamping groove 14 through one of the first through hole 111 and the second through hole 112, and then exit through the other of the first through hole 111 and the second through hole 112. Since the clamping part is located between the first through hole 111 and the second through hole 112, the pressing part 113 and the pressing member 2 can jointly clamp the portion of the shoulder strap housed in the clamping groove 14, thereby achieving locking between the shoulder strap and the buckle 100. In this embodiment, by providing the first through hole 111 and the second through hole 112, the item to be locked can be inserted into the clamping groove 14 through one of the first through hole 111 and the second through hole 112, and then exit through the other of the first through hole 111 and the second through hole 112. This helps to increase the contact area between the item to be locked and the buckle 100, thereby reducing the risk of the item to be locked sliding relative to the buckle 100.

[0057] In some embodiments, the surface of the pressing part 113 facing the pressing member 2 is provided with a grid pattern 114, which helps to increase the friction between the item to be locked and the pressing part 113, further reducing the risk of the item to be locked sliding relative to the latch 100 and improving the locking ability of the latch 100.

[0058] In some embodiments, the end of the holding member 2 facing the base plate 11 is provided with a plurality of protrusions 23, which are spaced apart. The protrusions 23 are used to abut against the surface of the item to be locked away from the holding part 113, or when the item to be locked is textile, the protrusions 23 can also pass directly through the item to be locked. This arrangement helps to further improve the locking ability of the latch 100 to lock external items and reduces the risk of the item to be locked sliding relative to the latch 100.

[0059] In some embodiments, please refer to Figure 7The pressing part 113 has a stepped part 1131 on its surface facing the pressing member 2, and the pressing member 2 has a pressing boss 29 on its surface facing the base plate 11. The stepped part 1131 is used to engage with the pressing boss 29, thereby pressing the item to be locked between the stepped part 1131 and the pressing boss 29. In this embodiment, by providing the stepped part 1131 and the pressing boss 29, the contact area between the item to be locked and the pressing member 2 and the base plate 11 can be increased, thereby increasing the friction between the item to be locked and the latch 100, thus improving the locking ability of the latch 100 to lock the item and reducing the risk of the item to be locked sliding relative to the latch 100.

[0060] It is worth noting that the aforementioned mesh pattern 114 and protrusions 23 are non-essential structures; that is, in some embodiments, please refer to [the documentation / reference needed]. Figure 8 The surface of the holding part 113 is not provided with the aforementioned grid pattern 114, and the surface of the holding member 2 is not provided with protrusions 23. Under the action of the elastic member 3, the holding part 113 and the holding part can also keep the item to be locked pressed tightly.

[0061] In some embodiments, at least one of the first side plate 12 and the second side plate 13 is provided with a limiting groove 15, the limiting groove 15 being located on the side of the first side plate 12 or the second side plate 13 away from the base plate 11. The pressing member 2 is provided with a limiting boss 24, the limiting boss 24 being removably received in the limiting groove 15, and the limiting boss 24 being used to abut against the bottom of the limiting groove 15, thereby limiting the rotational stroke of the pressing member 2 relative to the base 1.

[0062] In some embodiments, the end of the holding member 2 facing the base plate 11 is provided with a relief slope 25. Along the first direction X, the distance between the relief slope 25 and the base plate 11 gradually increases from the end of the relief slope 25 near the first protrusion 21 to the end away from the first protrusion 21. This arrangement allows the user to easily insert part of their finger between the relief slope 25 and the base plate 11, making it convenient for the user to rotate the holding member 2, thereby facilitating the user to adjust the length of the shoulder strap or to detach the shoulder strap from the buckle 100.

[0063] In some embodiments, please refer to Figure 9 The latch 100 is also provided with a male end connector 5, which is located at the end of the base 1 away from the holding member 2. The male end connector 5 is used to engage and fix with the female end connector 6 of other fasteners, thereby fixing the latch 100 to other fasteners. It is worth noting that the other fasteners can be latches 100 with female end connectors 6.

[0064] In some embodiments, please refer to Figure 9The latch 100 is provided with a female connector 6, which is located at the end of the base 1 away from the holding member 2. The female connector 6 is used to engage and fix with the male connector 5 of other fasteners, thereby fixing the latch 100 to other fasteners. It is worth noting that the other fasteners can be latches 100 that are provided with male connector 5.

[0065] In some embodiments, please refer to Figure 10 Along the first direction X, a relief groove 27 is provided at the end of the holding member 2 away from the first protrusion 21. The relief groove 27 is provided on the surface of the holding member 2 facing the base plate 11. By providing the relief groove 27, it is convenient for the user to place at least part of their finger in the relief groove 27, thereby opening the holding member 2.

[0066] In some embodiments, please refer to Figure 11 Along the first direction X, the holding member 2 protrudes at least partially from the base plate 11. The portion of the holding member 2 protruding from the base plate 11 is used for the user's fingers to grip, so that the user can open the holding member 2.

[0067] In this embodiment, by providing a clamping groove 14 on the base 1, the clamping groove 14 is configured to accommodate at least a portion of the item to be locked. By rotating the first protrusion 21 of the pressing member 2 in the first rotating hole 121 and rotating the second protrusion 22 in the second rotating hole 131, the pressing member 2 can rotate relative to the base 1. By sleeved on the first protrusion 21, one end of the elastic member 3 abuts against the base 1 and the other end abuts against the pressing member 2, the elastic member 3 can drive the pressing member 2 to remain abutting against the item to be locked. Thus, the base 1 and the pressing member 2 jointly press the item to be locked, which helps to improve the stability of the connection between the item to be locked and the latch 100 and reduces the risk of the item to be locked sliding relative to the latch 100.

[0068] This application also provides an embodiment of a locking assembly 1000; please refer to [link / reference]. Figure 9 The locking assembly 1000 includes at least two locking buckles 100, one of which is provided with a male end connector 5 and the other is provided with a female end connector 6. The male end connector 5 is detachably engaged in the slot 61 of the female end connector 6, thereby achieving the fixation between the two locking buckles 100.

[0069] This application also provides embodiments of the strap assembly 2000, please refer to [link / reference]. Figure 12The strap assembly 2000 includes a strap 200 and the aforementioned buckle 100. At least a portion of the strap 200 is removably received within a clamping groove 14. When the strap 200 is partially received within the clamping groove 14, the clamping member 2 presses against the surface of the strap 200 facing away from the base plate 11, thereby securing the strap 200 to the buckle 100. When the clamping member 2 is opened to release the clamping member 2 from the strap 200, the strap 200 can slide relative to the buckle 100, thereby adjusting the position of the strap 200 held by the clamping member 2 and thus adjusting the binding length of the strap 200.

[0070] This application also provides an embodiment of a backpack (not shown in the figure). The backpack includes a body, shoulder straps, and the aforementioned buckle 100.
