Description
Technical Field
[0001] This utility model relates to a bag structure, and more particularly to a bag with a telescopic gusset. Background Technology
[0002] Luggage with a telescopic flap refers to a bag with an additional telescopic flap in the middle of the two flaps, which increases the bag's capacity, typically by 10%-30% from the base size. Compared to regular luggage, its core advantage lies in its dynamic adaptation to needs. For example, it can be temporarily expanded to accommodate more items during travel, and its volume can be compressed for daily storage to maintain a compact structure and prevent the bag from taking up too much space.
[0003] However, the overall structure of existing bags with elastic flaps is relatively loose compared to conventional bags. Especially when not fully packed, the bag is not compact enough and is prone to slight deformation or lack of three-dimensionality. Utility Model Content
[0004] Therefore, it is necessary to provide a bag with a retractable circumference to address the shortcomings of existing technologies.
[0005] A bag with a telescopic enclosure includes a first shell, a second shell disposed on the front side of the first shell and opposite to the first shell, a telescopic enclosure connecting the first and second shells, and a telescopic frame disposed inside the telescopic enclosure and connecting the first and second shells. The first shell, the second shell, and the telescopic enclosure together form an inner space. The telescopic enclosure can be telescopically adjusted. The telescopic frame includes a first guide rail, a first slider slidably mounted on the first guide rail, a second guide rail, a second slider slidably mounted on the second guide rail, a first support rod movably mounted on the second guide rail and the first slider, a second support rod movably mounted on the first guide rail and the second slider, and an elastic element. The first guide rail and the second guide rail are respectively mounted on the first shell and the second shell. The first support rod and the second support rod are arranged crosswise. The elastic element pulls one or both of the first slider and the second slider to move inward.
[0006] In one embodiment, the elastic element includes two return springs, which are respectively connected to the first slider and the second slider, and the two return springs pull the first slider and the second slider inward.
[0007] In one embodiment, both the middle portion of the first guide rail and the middle portion of the second guide rail are provided with protrusions, wherein the two ends of a return spring are respectively mounted on the protrusion of the first guide rail and the first slider, and the two ends of a return spring are respectively mounted on the protrusion of the second guide rail and the second slider.
[0008] In one embodiment, the telescopic frame is in two sets, which are arranged opposite each other inside the inner space. Each set of telescopic frames is connected to the first and second housings on the same side.
[0009] In one embodiment, the first housing shell is provided with a first receiving groove with an opening on the side of the second housing shell, and the second housing shell is provided with a second receiving groove with an opening on the side of the first housing shell. One end of the telescopic enclosure is distributed along the opening of the first receiving groove and installed inside the opening of the first receiving groove, and the other end of the telescopic enclosure is distributed along the opening of the second receiving groove and installed inside the opening of the second receiving groove.
[0010] In one embodiment, the telescopic frame further includes a button for locking the second slider. The button is mounted on the second housing and extends into the path of the second slider as it moves outward. When the second slider moves to a position that engages with the button, the button engages with the second slider.
[0011] In one embodiment, the telescopic frame further includes several positioning pins. When the first support rod is installed in conjunction with the second guide rail and the first slider, one positioning pin passes through one end of the first support rod and the second guide rail, and the other positioning pin passes through the other end of the first support rod and the first slider.
[0012] In one embodiment, when the second support rod is installed in conjunction with the first guide rail and the second slider, one positioning pin passes through one end of the second support rod and the first guide rail, and the other positioning pin passes through the other end of the second support rod and the second slider.
[0013] In one embodiment, one of the positioning pins of the telescopic frame passes through the intersection of the first support rod and the second support rod, thereby allowing the included angle between the first support rod and the second support rod to be adjusted.
[0014] The beneficial effects of this utility model of a bag with a telescopic enclosure are as follows: based on the telescopic enclosure, a telescopic frame is further provided. The telescopic frame includes a first guide rail, a first slider slidably mounted on the first guide rail, a second guide rail, a second slider slidably mounted on the second guide rail, a first support rod movably mounted on the second guide rail and the first slider, a second support rod movably mounted on the first guide rail and the second slider, and an elastic element. The first guide rail and the second guide rail are respectively mounted on the first box shell and the second box shell. The first support rod and the second support rod are arranged in a cross pattern. The elastic element pulls one or both of the first slider and the second slider to move inward, making the telescopic frame less prone to deformation, thereby making the bag's body structure more compact.

[0027] Please see Figures 1 to 6 This utility model provides a bag with a telescopic enclosure, including a first shell 10, a second shell 20 disposed on the front side of the first shell 10 and opposite to the first shell 10, a faceplate 30 disposed on the front side of the second shell 20, a zipper assembly 50 connecting the second shell 20 and the faceplate 30, a pulley assembly 60 installed at the bottom of the first shell 10 and the second shell 20, a pull rod 70 installed on the first shell 10, a telescopic enclosure 40 connecting the first shell 10 and the second shell 20, and a telescopic frame 80 disposed inside the telescopic enclosure 40 and connecting the first shell 10 and the second shell 20. The first shell 10, the second shell 20 and the telescopic enclosure 40 together form an inner space. The telescopic enclosure 40 can be telescopically adjusted to adjust the size of the inner space. The telescopic frame 80 assists in shaping the telescopic enclosure 40. When the first shell 10 moves closer to the second shell 20 to a set position, the telescopic frame 80 is in a locked state.
[0028] The first housing 10 has a first receiving groove 11 with an opening on the side adjacent to the second housing 20, and the second housing 20 has a second receiving groove 21 with an opening on the side adjacent to the first housing 10. The telescopic enclosure 40 is made of foldable fabric and is arranged in a ring shape. One end of the telescopic enclosure 40 is distributed along the opening of the first receiving groove 11 and installed inside the opening of the first receiving groove 11, and the other end of the telescopic enclosure 40 is distributed along the opening of the second receiving groove 21 and installed inside the opening of the second receiving groove 21. The pulley assembly 60 includes multiple pulleys, which are divided into two groups and respectively installed on the first housing 10 and the second housing 20.
[0029] The telescopic frame 80 consists of two sets, arranged opposite each other within the inner space. Each set of telescopic frames 80 connects to the first housing 10 and the second housing 20 on the same side. Each set of telescopic frames 80 includes a first guide rail 81, a first slider 83 slidably mounted on the first guide rail 81, a second guide rail 82, a second slider 84 slidably mounted on the second guide rail 82, a first support rod 85 movably mounted on the second guide rail 82 and the first slider 83, a second support rod 86 movably mounted on the first guide rail 81 and the second slider 84, several positioning pins 88, elastic elements, and a button 89 for locking the second slider 84. The first guide rail 81 and the second guide rail 82 are respectively mounted on the first housing 10 and the second housing 20. The first slider 83 and the second slider 84 are arranged opposite each other. The support rod 85 and the second support rod 86 are arranged in a cross configuration. The elastic element pulls one or both of the first slider 83 and the second slider 84 inward. In this embodiment, the elastic element includes two return springs 87, which are respectively connected to the first slider 83 and the second slider 84. The two return springs 87 pull the first slider 83 and the second slider 84 inward. The button 89 is installed in the second housing 20 and extends into the path of the second slider 84 as it moves outward. When the second slider 84 moves to the position that engages with the button 89, the button 89 is engaged in the second slider 84 to limit the movement of the second slider 84.
[0030] Specifically, the first guide rail 81 and the second guide rail 82 have similar structures, and the first slider 83 and the second slider 84 have similar structures. The second guide rail 82 is provided with a T-shaped groove 821 that is wider on the inside and narrower on the outside. The cross-section of the second slider 84 is arranged in an inverted T shape. The two sides of the second slider 84 are engaged in the T-shaped groove 821, and the middle part of the second slider 84 extends out from the T-shaped groove 821. When the first support rod 85 is installed in conjunction with the second guide rail 82 and the first slider 83, one positioning pin 88 passes through one end of the first support rod 85 and the second guide rail 82, and the other positioning pin 88 passes through the other end of the first support rod 85 and the first slider 83.
[0031] When the second support rod 86 is installed in conjunction with the first guide rail 81 and the second slider 84, one positioning pin 88 passes through one end of the second support rod 86 and the first guide rail 81, and the other positioning pin 88 passes through the other end of the second support rod 86 and the second slider 84. This allows the two ends of the first support rod 85 to be movably mounted on the second guide rail 82 and the first slider 83, and the two ends of the second support rod 86 to be movably mounted on the first guide rail 81 and the second slider 84. In addition, one positioning pin 88 passes through the intersection of the first support rod 85 and the second support rod 86, thereby allowing the included angle between the first support rod 85 and the second support rod 86 to be adjusted.
[0032] Both the first guide rail 81 and the second guide rail 82 have protrusions 810 in the middle. A return spring 87 is installed at both ends on the protrusions 810 and the first slider 83 of the first guide rail 81, and at both ends on the protrusions 810 and the second slider 84 of the second guide rail 82. The back of the second slider 84 has a slot 841. The second guide rail 82 has a through hole 822 at the position corresponding to the button 89. The button 89 includes a base 981, a button body 892, a retaining strip 893 connected to one end of the button body 892, and a button 89 spring that elastically abuts against the other end of the button body 892. The middle part of the button body 892 is rotatably mounted on the base 981. In the initial state, the button 89 spring pushes the button body 892, causing the retaining strip 893 to pass through the through hole 822 and extend into the movement path of the second slider 84. Pressing the end of the button body 892 near the button 89 spring causes the retaining strip 893 to exit from the movement path of the second slider 84.
[0033] When the telescopic enclosure 40 is not needed to increase the internal space, press the first box shell 10 or the second box shell 20 to bring them closer together. The telescopic frame 80 retracts, and the first slider 83 and the second slider 84 move outwards simultaneously. The return spring 87 deforms and increases. When the second slider 84 slides past the locking strip 893, the locking strip 893 engages in the locking groove 841. At this time, the telescopic frame 80 is in a locked state, and the telescopic frame 80 tightens the first box shell 10 and the second box shell 20, making the bag less prone to deformation.
[0034] When the telescopic frame 40 is needed to increase the internal space, press the end of the button body 892 near the button 89 spring. The locking strip 893 disengages from the movement path of the second slider 84. The return spring 87 connected to the first slider 83 drives the first slider 83 to move closer to the middle of the first guide rail 81. The return spring 87 connected to the second slider 84 drives the second slider 84 to move closer to the middle of the second guide rail 82. The telescopic frame 80 is in the open state. During use, because the two return springs 87 apply a pulling force to the first slider 83 and the second slider 84 respectively, the telescopic frame 80 is not easily deformed, thus making the bag body structure more compact.
[0035] Understandably, in this embodiment, two return springs 87 are used to pull the first slider 83 and the second slider 84 inward respectively. In other embodiments, if the pulling force of the return spring 87 is large enough, only one return spring 87 may be used.
[0036] The beneficial effects of this utility model of a bag with a telescopic enclosure are as follows: Based on the telescopic enclosure 40, a telescopic frame 80 is further provided. The telescopic frame 80 includes a first guide rail 81, a first slider 83 slidably mounted on the first guide rail 81, a second guide rail 82, a second slider 84 slidably mounted on the second guide rail 82, a first support rod 85 movably mounted on the second guide rail 82 and the first slider 83, a second support rod 86 movably mounted on the first guide rail 81 and the second slider 84, and an elastic element. The first guide rail 81 and the second guide rail 82 are respectively mounted on the first case 10 and the second case 20. The first support rod 85 and the second support rod 86 are arranged in a cross pattern. The elastic element pulls one or both of the first slider 83 and the second slider 84 to move inward, making the telescopic frame 80 less prone to deformation, thereby making the bag's body structure more compact.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
