Description

TECHNICAL FIELD

[0001] The present application relates to the field of zippers, in particular to a luggage accessory with the function of zipper opening and closing teeth of a lower stop and a puller. BACKGROUND

[0002] Luggage is an indispensable commodity when traveling. In response to customs pressure and the principle of making the most of it, users can disassemble and reassemble or exchange the required capacity or other special functions. Most of the luggage shells are connected by zippers. However, the size of the zipper is basically a closed and open zipper. The closed zipper cannot be disassembled after the upper and lower stops are fixed. Although the open zipper can be disassembled and reassembled, when the single-sided chain belt with a latch at the open end is "sewn to the shell", it cannot be inserted into the lower stop to open and close the teeth in the traditional way. It is very inconvenient to operate and cannot be used for four-wheel landing correction of the luggage. SUMMARY

[0003] The present application provides a luggage accessory with the function of zipper opening and closing teeth of a lower stop and a puller. The purpose is to solve the shortcomings of the prior art and meet the needs of disassembly and assembly. DIY disassembly and assembly can be exchanged with different colors or different capacities or shapes in the same box frame length.

[0004] The technical solution adopted by the present application to solve its technical problems is: The lower stop includes a main body and a spring. The main body includes a lower cover plate and an upper cover plate connected by a base. A hole is provided on the lower cover plate, and a spring is provided on the lower cover plate corresponding to the hole. One end of the spring is fixed to the lower cover plate as a fixed end, and the other end is a free end. The free end is a bent sharp piece or a needle-shaped stop needle, and the stop needle is opposite the hole. A recess, i.e. a "M" shaped arch part, is provided behind the stop needle. The key grip has a lifting column. The lifting column is inserted into the recess to lift the stop needle and unlock. The lifting column is separated from the recess, and the stop needle is pressed through the hole into the tooth gap to lock.

[0005] The left and right sides of the lower cover plate and the upper cover plate of the main body are provided with side guards, and the lower cover plate and the upper cover plate form a "Y" type inner cavity channel. The lower cover plate can select a spring hook or a cap-shaped hook of a full-automatic or semi-automatic puller. The hook is needle or piece lock type.

[0006] The area of the upper cover plate is larger than that of the lower cover plate, which has the function of covering and protecting the outer surface.

[0007] The fixed end of the elastic sheet is fixed by a deep hole in the base plate, and the fixed end of the elastic sheet is elastically fixed in the deep hole.

[0008] The lower cover plate of the lock-on lower stopper has a protruding guide wall in front of the insertion hole, protruding positioning abutting walls on both sides of the insertion hole, and a protruding positioning wall behind the insertion hole. The key grip piece has a hand holding portion at one end and a top-up column and a guide column at the other end. The top-up column is located between the hand holding portion and the guide column. The hand holding portion and the top-up column have a recess for allowing space. The side of the hand holding portion and the recess is the abutting side. The top-up column and the guide column have a top guide recess. When the key grip piece is combined with the lock-on lower stopper, the top-up column is inserted into the recess of the elastic sheet, i.e., the M-shaped arch portion. The guide column is positioned and shaped by the guide wall and the positioning abutting wall. The guide column is inserted between the guide wall and the positioning abutting wall. The guide wall can be operated blindly into the top guide recess.

[0009] In addition, a limiting cover can be provided on the lock-on lower stopper.

[0010] The use method of the above-mentioned luggage accessory is characterized in that the lock-on lower stopper and the key grip piece are two independent components. The lock-on lower stopper is installed on the luggage, and the key grip piece is stored separately.

[0011] The abutting side of the key grip piece is used as a support point to abut against the positioning wall. The key grip piece is moved horizontally. The top-up column is inserted into the upper curved portion of the elastic sheet. The guide column is inserted between the guide wall and the positioning abutting wall. The guide wall is inserted into the guide recess. The top-up column lifts the elastic sheet. The key grip piece is in an unlocked state. Then, the key grip piece is inserted into the chain and sprocket belt of the luggage. The key grip piece is removed by reverse operation at an appropriate position. The top-up column is separated from the upper curved portion of the elastic sheet. The guide column is separated from between the guide wall and the positioning abutting wall. The elastic sheet is reset due to elasticity. The needle of the elastic sheet passes through the insertion hole immediately. The insertion hole is pressed into the chain tooth. The locking purpose is achieved.

[0012] The lower cover plate of the lock-on lower stopper has a protruding guide wall in front of the insertion hole, protruding positioning abutting walls on both sides of the insertion hole, and a protruding positioning wall behind the insertion hole. The key grip piece has a hand holding portion at one end and a top-up column and a guide column at the other end. The top-up column is located between the hand holding portion and the guide column. The hand holding portion and the top-up column have a recess for allowing space. The side of the hand holding portion and the recess is the abutting side. The top-up column and the guide column have a top guide recess. The key grip piece has an inclined portion connecting the hand holding portion. The inclined portion has a clamping groove facing the top-up column 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 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: Improvement of mechanical structure: The camshaft type semi-automatic brake of the prior art is changed to a horizontal shield lifting by manually taking the lock key grip piece.

[0019] B: Improvement of use method: The prior art is to control the spring piece sharp tail lock piece (needle) to be pressed down for locking by the high-low difference of the mechanical camshaft rotation, and the present patent is to directly lift the sharp tail lock needle (piece) of the spring piece (wire) by horizontally displacing the F-shaped lock key grip piece into the "ㄇ" type concave part of the spring piece. Once the F-shaped lock key grip piece is pulled out, the spring piece (wire) is naturally pressed down to achieve the locking effect. The F-shaped lock key grip piece is usually placed in the bag to achieve the effect of safety protection.

[0020] C: Improvement of appearance: The upper and lower cover plates of the traditional YG semi-automatic head cavity of the prior art are equal in width and length. The pulling force of the zipper tape connecting the case shell and the correction in the opposite direction are changed by adjusting the gear position, so after correcting the 4-wheel landing balance, it is often the phenomenon of one side being long and the other side being short. The upper cover plate of the present patent is wider and is usually enough to cover the unattractive appearance of one side being long and the other side being short, and is used for safety protection against damage.

[0021] D: Improvement of structure: The upper view guide groove can control the 3D space form positioning to make the lifting column correctly correspond to the "ㄇ" type arch part of the spring piece for blind spot operation horizontal displacement. BRIEF DESCRIPTION OF DRAWINGS
