Description

Technical Field

[0001] This invention relates to the field of zippers, specifically a bag accessory that can be selected as a locking type lower stop and also functions as a zipper pull for opening and closing chain teeth. Background Technology

[0002] Luggage is an indispensable item for travel. To cope with tariff pressures and the principle of making the most of resources, and with the concept that users can disassemble and reassemble or exchange luggage for desired capacity or other special functions, most suitcases use zippers to connect the two halves of the suitcase. However, zippers are basically either closed or open. Once the top and bottom stops of a closed zipper are fixed, the two halves of the suitcase cannot be separated. While open zippers can be disassembled and reassembled, once the single-sided chain with a pin at the open end is "sewn to the suitcase shell," it cannot be pulled back to insert into the bottom stop for a traditional opening and closing mechanism, making operation extremely inconvenient. Furthermore, it cannot be used for misaligned closing to correct the four wheels' contact with the ground. Utility Model Content

[0003] This invention provides a luggage accessory with a selectable locking lower stop that also functions as a zipper pull and chain teeth. Its purpose is to overcome the shortcomings of the existing technology and meet the requirements of being detachable and combinable. It allows for DIY detachable and combinable modular luggage that can be interchanged with different colors, capacities, or shapes within the same frame length.

[0004] The technical solution adopted by this invention to solve its technical problem is: The locking mechanism includes a main body and a spring clip. The main body includes a lower cover plate and an upper cover plate, which are connected by a core. The lower cover plate has an insertion hole, and a spring clip is provided on the lower cover plate corresponding to the insertion hole. One end of the spring clip is a fixed end fixed to the lower cover plate, and the other end is a free end, which is a stop pin bent into a pointed or needle-like shape, with the stop pin facing the insertion hole. The spring clip also has a recessed part, i.e., a U-shaped arched part, after the stop pin. The key grip has a lifting post. The lifting post is inserted into the recess and lifts the stop pin to unlock. When the lifting post is disengaged from the recess, the stop pin is pressed down and passes through the insertion hole into the tooth gap to lock.

[0005] The lower cover plate and the upper cover plate of the main body are provided with side guard plates on the left and right sides. There is a "Y" shaped internal cavity channel between the lower cover plate and the upper cover plate. The lower cover plate can be equipped with a spring hook or a cap-shaped hook, such as a fully automatic or semi-automatic zipper. The hook is a needle or a plate lock type.

[0006] The area of ​​the upper cover is larger than that of the lower cover, providing external covering and protection.

[0007] The fixing method of the fixed end is as follows: a core-connected deep hole is set on the lower cover plate so that the locking part of the fixed end of the spring clip can be elastically locked with the corresponding locking part at the end of the deep hole, or a cow-ear type spring clip fixing seat for riveting is set on the outer end of the core to firmly rivet the fixed end of the spring clip.

[0008] The lower cover plate of the locking type lower stop has a raised guide wall in front of the adjacent socket, and the lower cover plate has raised positioning abutment walls on both sides of the socket, and a raised positioning wall is provided behind the socket. One end of the key grip is a hand grip, and the other end has a lifting post and a guide post. The lifting post is located between the hand grip and the guide post. There is a clearance groove between the lifting post and the hand grip. The side where the hand grip meets the clearance groove is the abutment side. There is an upward guide groove between the lifting post and the guide post. When the key grip is combined with the locking lower stop, the jacking post is inserted into the recess of the spring, which is also the U-shaped arched part. The guide post is subject to the positional shape space of the guide wall and the positioning abutment wall. The guide post is inserted between the guide wall and the positioning abutment wall. The guide wall can be operated blindly to enter the upper guide groove.

[0009] Alternatively, a limiting cover can be provided on the locking lower stop, with the limiting cover located above the spring piece.

[0010] The method of using the above-mentioned bag accessories is characterized in that: the locking lower stop and the key grip are two independent parts, the locking lower stop is installed on the bag, and the key grip is stored separately.

[0011] Place the side of the key grip against the positioning wall as a support point, move the key grip laterally, lift the column and insert it into the upper bend of the spring, insert the guide column between the guide wall and the positioning wall, insert the guide wall into the guide groove, lift the column and lift the spring, and the key grip is in the unlocked state. Then, insert the toothed chain strap into the bag, select an appropriate position, and reverse the operation to remove the key grip. Lift the column to disengage from the upper curved part of the spring, and the guide column will disengage from the guide wall and the positioning abutment wall. Due to the elastic reset of the spring, the spring's retaining pin will pass through the insertion hole and be pressed down to insert between the chain teeth to achieve the locking purpose.

[0012] The lower cover plate of the locking type lower stop has a raised guide wall in front of the adjacent socket, and the lower cover plate has raised positioning abutment walls on both sides of the socket, and a raised positioning wall is provided behind the socket. One end of the key grip is a hand grip, and the other end has a lifting post and a guide post. The lifting post is located between the hand grip and the guide post, and there is an upward guide groove between the lifting post and the guide post. There is a clearance groove between the lifting post and the hand grip. The middle part of the key grip is an inclined part that connects to the hand grip. There is a slot in the middle of the inclined part that faces the lifting post, which can be used to insert the top cover for visual positioning. When the key grip is combined with the locking lower stop, the jacking post is inserted into the recess of the spring, which is also the U-shaped arched part. The guide post is subject to the positional shape space of the guide wall and the positioning abutment wall. The guide post is inserted between the guide wall and the positioning abutment wall. The guide wall can be operated blindly to enter the upper guide groove.

[0013] Insert the key grip into the slot of the locking lower stop and onto the upper cover plate. The upper cover plate serves as a support point. Move the key grip laterally and push up the column to insert into the recess of the spring. Insert the guide column between the guide wall and the positioning abutment wall. Insert the guide wall into the upper guide groove. Push up the column to push up the spring, and the key grip is in the unlocked state. Then, insert the toothed chain strap into the bag, select an appropriate position, and reverse the operation to remove the key grip. Lift the post to disengage from the recess of the spring, and guide the post to disengage from the guide wall and the positioning abutment wall. Due to the elastic reset of the spring, the spring's retaining pin passes through the insertion hole and is pressed down to insert between the chain teeth, thus achieving the purpose of locking.

[0014] The snap-lock type lower stop is used on the main zipper of luggage. When the main zipper is designed to be stitched onto the box shell, after the main zipper is adjusted by the two opposite zipper heads to make staggered teeth to achieve four-wheel ground balance, the snap-lock type lower stop can be inserted into the end of the toothed chain with one long and one short teeth on the outer surface of the box shell for locking and protection.

[0015] The snap-lock bottom stop is used on the main zipper of a suitcase. When the main zipper is not overlapped with the suitcase shell, an open zipper is used as the secondary zipper. After the main zipper passes through the two opposing zipper heads to complete the engagement teeth and four-wheel alignment and balance check, the secondary zipper is sewn on according to the corresponding position of the secondary zipper starting point on the suitcase shell. This replaces the traditional left and right shell connecting tape of the suitcase. Before sewing the secondary zipper, the snap-lock bottom stop is inserted into the secondary zipper. At this time, when the snap-lock bottom stop key handle is inserted into the recess of the spring, it is in the unlocked state. The snap-lock bottom stop can slide like a zipper head to open and close. When the snap-lock bottom stop moves to the top stop end, the key handle is removed, and the snap-lock bottom stop changes from a zipper head function to a bottom stop locking function. The suitcase can be DIY, disassembled, assembled, and interchanged.

[0016] The advantages of this invention are: This patent is a "locking bottom stop" that is both a slider and a box, which is different from the top stop, bottom stop, pin, and bottom stop that are fixed at the end and have a blocking effect. It breaks through the limitations of zipper application and meets the requirements of being detachable and combinable. It can be used to design and make DIY detachable and combinable modular suitcases with different colors, capacities or shapes that can be interchanged within the same frame length.

[0017] This patent is an improvement on the traditional YG semi-automatic spring head, using a spring sheet structure to achieve the function of pressing and locking.

[0018] A: Improvements to the mechanical structure: The existing camshaft-type semi-automatic brake has been replaced by a manual key-grabbing mechanism with a horizontal support.

[0019] B: Improvements to the usage method: Existing technology relies on the height difference of the mechanical camshaft rotation to control the spring plate tip locking plate (pin) to exert a downward pressing locking action. This patented design utilizes an F-shaped key grip that laterally displaces into the "U"-shaped recess of a spring plate, directly lifting the pointed locking pin (piece) of the spring plate (wire). Once the F-shaped key grip is withdrawn, the spring plate (wire) naturally presses down, achieving the locking effect. Furthermore, the F-shaped key grip is normally placed inside a bag or suitcase for enhanced security.

[0020] C: Appearance improvements: In existing conventional YG semi-automatic head unit, the upper and lower cover plates are of equal width and length. By adjusting the meshing teeth, the traction force of the zipper belt connecting the box shell and the reverse correction are changed. Therefore, after correcting the balance of the four wheels, there is often a phenomenon where one side is longer than the other. In contrast, the upper cover plate of this patent is wider and more often sufficient to cover the unsightly appearance of one side being longer than the other, and also to provide safety protection against collision damage.

[0021] D: Structural improvements: The upper guide groove can control the 3D spatial shape positioning so that the lifting column is correctly aligned with the U-shaped arch of the spring piece, which facilitates blind spot operation and lateral movement. Attached Figure Description

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown: This patent is a utility model for zipper accessories for bags, which meets the needs of DIY detachable and combinable luggage bags.

[0027] The main body 1 of this invention includes a lower cover plate 11 and an upper cover plate 12. Side guard plates 13 are provided on the left and right sides of the lower cover plate 11 and the upper cover plate 12. There is a "Y"-shaped internal cavity channel between the lower cover plate 11 and the upper cover plate 12. The lower cover plate 11 and the upper cover plate 12 are connected by a base. The base extends outward to connect the upper cover plate and the lower bottom plate as a beam and column to support the main body, making it impact-resistant and drop-resistant.

[0028] The area of ​​the upper cover plate 12 is larger than that of the lower cover plate 11, and it has the function of covering and protecting against external damage.

[0029] This patent uses the basic "Y"-shaped internal cavity channel of the zipper opening and closing teeth as the basis. Its structure is as follows: on the surface of the lower cover plate 11, there is an insertion hole 14. The lower cover plate 11 has two protrusions 15 in front of the insertion hole 14, which form a guide wall. The lower cover plate 11 has protrusions 16 on both sides of the insertion hole 14, which form a positioning abutment wall. A protruding positioning wall 17 is provided behind the insertion hole 14 for blind abutment positioning of the key grip 3.

[0030] The lower cover plate and the upper cover plate of the main body are provided with side guard plates on the left and right sides. There is a "Y" shaped internal cavity channel between the lower cover plate and the upper cover plate. The lower cover plate can be equipped with a spring hook or a cap-shaped hook, such as a fully automatic or semi-automatic zipper. The hook is a needle or a plate lock type.

[0031] The lower cover plate 11 is provided with a spring piece 2 corresponding to the insertion hole 14 (the spring piece 2 is the force source for locking, which is a spring piece with one end fixed and the other end movable. It can be stamped or formed by spiral winding of Tanxing steel wire. Therefore, any structure that generates the force of spring compression can be used).

[0032] A core-connected deep hole (a vertical deep hole is provided at the end of the core so that the locking part of the spring clip 21 can be elastically locked with the corresponding locking part at the end of the vertical deep hole) or a cow-ear type spring clip fixing seat (a cow-ear type spring clip fixing seat for riveting is provided at the outer end of the core to firmly rivet the fixing end 21 of the spring clip 2) is provided on the lower cover plate 11 to fix the non-locking end 21 of the spring clip 2 as the source of elastic force.

[0033] The other end of the spring 2 is a stop pin 22. The stop pin 22 is a pointed piece or needle that is bent by stamping and has a locking effect. It acts as a locking device. The pointed piece or needle-shaped locking part of the end of the stop pin 22 is bent vertically downward and is positioned directly opposite the insertion hole 14.

[0034] Furthermore, the spring piece 2 has a recess 23 (also known as a U-shaped arched part or an arc-shaped part) after the tip of the pin lock or plate lock of the stop pin 22. The recess 23 allows the "F" or "7" shaped lifting post 34 of the "F" or "7" shaped key grip 3 to be inserted through and thus lift the stop pin 22 (the tip or pin end), and the lifting post 34 can also be removed from the recess 23.

[0035] After the spring 2 is installed into the main body 1, it forms a locking lower stop 10.

[0036] One end of the key grip 3 is a hand grip 31, and the other end has a lifting post 34 and a guide post 36. The lifting post 34 is located between the hand grip 31 and the guide post 36. There is a clearance groove 33 between the lifting post 34 and the hand grip 31. The side where the hand grip 31 and the clearance groove 33 meet is an abutting side 32. There is an upward guide groove 35 between the lifting post 34 and the guide post 36.

[0037] The key grip 3 and the lock-type lower stop 10 are separate, and the key grip 3 can be placed inside the bag.

[0038] During operation: like Figure 6 , Figure 7 , Figure 8 As shown: Holding the key grip 31, with its abutting side 32 against the positioning wall 17 as a support point, the key grip 3 is moved laterally, lifting the column 34 to insert into the recess 23 of the spring piece 2. The guide column 36 is inserted between the guide wall and the positioning abutting wall, and the guide wall is inserted into the upward-looking guide groove 35, while the clearance groove 33 provides clearance. The cooperation between the abutting side 32 of the key grip 3 and the positioning wall 17, the cooperation between the guide column 36 and the guide wall and the positioning abutting wall, and the cooperation between the guide wall and the upward-looking guide groove 35 facilitates the blind insertion and precise insertion of the key grip 3 into the recess 23 of the spring piece.

[0039] Then press down the handle 31, lift the column 34 to lift the spring 2, and the key handle 3 is in the unlocked state. Then put it into the toothed chain of the bag. Select an appropriate position and then reverse the operation to remove the key handle 3. Lift the column 34 to disengage from the recess 23 of the spring 2. The guide column 36 disengages from the guide wall and the positioning abutment wall. Because the spring 2 is elastically reset, the stop pin 22 of the spring 2 passes through the insertion hole 14 and is pressed down to insert into the gap of the chain teeth to achieve the purpose of locking, forming a fixed lock plastic sleeve type lower stop pull head structure.

[0040] like Figure 13 As shown: The locking lower stop 10 (also serving as a zipper pull) is used on the main zipper of a suitcase. When the zipper is designed to be stitched to the case, after the main zipper is adjusted by the staggered teeth of the two opposing zipper pulls 500 to achieve four-wheel balance, the locking lower stop 10 (or zipper pull) of this design can be inserted into the end of the interlocking chain 200 with one long and one short teeth on the outer surface of the case for locking and protection. This stitching process, combined with the locking lower stop 10 as a DIY detachable and assembleable design method and structure, is one of the ways in which this invention can be used.

[0041] like Figure 14 As shown: When the main zipper is still the traditional method without overlapping seams, an open zipper 100' is used as a secondary zipper. After the main zipper 100 passes through the two opposing zipper heads 500 to complete the meshing and four-wheel alignment and balance check, the secondary zipper 100' (open zipper) is sewn on according to the corresponding position of the starting point on the suitcase shell. This serves as a replacement for the traditional left and right shell connecting tape. Before sewing the secondary zipper 100', the... The locking lower stop 10 (or zipper pull) is first inserted into the secondary zipper 100'. At this time, the lifting post 34 of the key handle 3 is inserted into the recess 23 of the spring 2. The locking lower stop 10 is in the unlocked state, and the main body can slide like a zipper pull to open and close. When the locking lower stop 10 (or zipper pull) moves to the end of the upper stop 400, the key handle 3 is removed, and the locking lower stop 10 changes from the zipper pull function to the lower stop locking function. This is a DIY detachable and interchangeable suitcase.

[0042] The following are four examples of the application of the locking-type lower zipper of this invention in the main zipper of bags: Figure 9 Model A features a reverse zipper, meaning the upper cover 12 of the snap-lock lower stop 10 is located on the opposite side of the zipper strap 200.

[0043] Figure 10 Model B has a zipper that goes through the front, meaning that the upper cover 12 of the snap-lock lower stop 10 is located on the same side as the zipper strap of the zipper 100.

[0044] Figure 11 Model C is a traditional open zipper with a bottom stop 300, but it omits the top stop and replaces it with a lock-type bottom stop 10. The lock-type bottom stop 10 works with the chain strap 200 of the zipper 100, so that when unlocking, it can slide like the zipper head, and when pulled to the top, the key grip 3 is removed and locked like the top stop.

[0045] Figure 12 Model D uses the locking lower stop 10 as a traditional pin and box. This model is equipped with a top stop 400 and a traditional zipper pull 500 that works with the chain strap 200 of the zipper 100.

[0046] The above four zipper accessories can all be combined and standardized according to the bag design. Modular design of hard and soft sections in the bag allows DIY users to choose and match to create their desired personalized products.

[0047] like Figure 15 As shown: This invention is applied to an embodiment of a bag with a folding main zipper.

[0048] The circled area on the right side of the image is an enlarged view of the area the lines are pointing to.

[0049] The zipper 100 of the bag 1000 is a stacked type, and the lock-type lower stop 10 works with the chain strap 200 of the zipper 100. The key handle 3 is stored separately. When in use, the key handle 3 is used to lock or unlock the lock-type lower stop 10 to enable it to function as a zipper pull.

[0050] like Figure 16 As shown: This invention is applied to one embodiment of a bag with a non-seamless folding main zipper.

[0051] The circled area on the right side of the image is an enlarged view of the area the lines are pointing to.

[0052] The zipper 100 of the bag 1000 is non-overlapping. The two locking bottom stops 10 are respectively engaged with the two ends of the chain strap 200 of the zipper 100 to form the bottom stops at both ends. The key handle 3 is stored separately. When in use, the key handle 3 is used to lock or unlock the locking bottom stops 10.

[0053] like Figure 17 As shown: This invention is applied to a second embodiment of a bag with a non-seamless folding main zipper.

[0054] The circled area on the right side of the image is an enlarged view of the area the lines are pointing to.

[0055] The zippers on the bags are non-overlapping.

[0056] The main zipper 100 of the main bag 1000 and the main chain strap 200 of the auxiliary zipper 100' of the auxiliary bag 100' are respectively equipped with a lower stop 300 and a top stop 400.

[0057] The snap-lock lower stop 10 and the secondary zipper 100' of the secondary zipper 200' work together to form a zipper pull. The key grip 3 is stored separately. When in use, the key grip 3 is used to lock or unlock the snap-lock lower stop 10. The two sides of the bag can be replaced to create a DIY detachable, assembleable and interchangeable suitcase.

[0058] The aforementioned key grip 3 is a nearly flat part, which is often inconvenient to insert into the bag to work with the snap lock lower stop 10.

[0059] When the key grip 3 pushes up the spring 2, the aforementioned locking mechanism 10 may over-push up the spring 2 and cause damage.

[0060] like Figure 18 , Figure 19 As shown: The second type of key grip has an inclined portion 37 in the middle that connects to the grip portion 31. The inclined portion 37 has a protrusion 38 in the middle that faces the lifting column 34, and the end of the protrusion 38 is a slot 39.

[0061] like Figure 20 , Figure 21 As shown: The locking type lower stop 10 is provided with a limiting cover 18. One end of the limiting cover 18 is fixed to the positioning wall 17 at the rear, and the other end is fixed to the two protrusions 15 at the front to form a guide wall. The limiting cover 18 is located above the spring piece 2.

[0062] During operation: The key grip 31 is held by the hand grip 31, and the slot 39 is inserted into the upper cover plate 12 of the locking lower stop 10 for positioning. The upper cover plate 12 serves as a support point. The key grip 3 is moved laterally, and the lifting column 34 is inserted into the recess 23 of the spring piece 2. The guide column 36 is inserted between the guide wall and the positioning abutment wall. The guide wall is inserted into the upper guide groove 35, and the clearance groove 33 plays a clearance role. The lifting column 34 lifts the spring piece 2, and the key grip 3 is in the unlocked state. The key grip 3 is removed, and the spring piece 2 returns to its original elastic state, forming a locked state.

[0063] When the second type of key grip 3 is used, the slot 39 and the upper cover plate 12 of the lock-type lower stop 10 are engaged and positioned with each other. The slot 39 can be inserted into the upper cover plate 13 and abutted against it. The "upward positioning" value is taken as the inner horizontal length and the vertical 3D space for blind high-precision positioning, which is convenient and reliable to use.

[0064] The second type of locking lower stop 10 adds a limiting cover 18, which limits the upward movement of the spring piece 2 and makes it less prone to damage.

[0065] Compared with existing technologies, this patent does not have left and right bull-ear seats for riveting pull tabs; instead, it adds positioning walls, guide walls, and F key grips for manual locking / unlocking.

[0066] This invention can be applied to a series of independent toothed particles for metal zippers or plastic steel zippers.

[0067] For bags, the manual locking and unlocking method, with the bottom bar on the outside of the bag and the key handle inside, can actually ensure security and prevent theft.

[0068] The cavity of this utility model is the cavity of a semi-automatic or automatic zipper pull. As long as the lower stop or the body of the zipper pull has an upper cover area larger than a lower cover area, and the structure is formed by bending a spring sheet or needle thread to provide elastic pressing force, it falls within the scope of protection of this patent.

[0069] Furthermore, any structure that modifies the stop pin structure of semi-automatic and automatic heads by using a method of "inserting a horizontal key and lifting the stop pin to unlock" is within the scope of this patent.

[0070] The various embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention.
