Description

一种四边开合的箱包A four-sided opening and closing bag

技术领域technical field

本发明涉及日常生活用品领域，特别涉及一种四边开合的箱包。The invention relates to the field of daily necessities, in particular to a case and bag with four sides opening and closing.

背景技术Background technique

箱包是人们最常用的一种生活用品，其提供携带物品便利功能的同时还具有明显的时代特性，附带有明显的时尚特性。为了能够明确反映这些特性，人们不停地开发和实验各种用来制作箱包的材料、结构、美观以及性能。常见的箱包一般有手提式或推拉式。对于手提式箱包，其使用起来比较方便，但是其体积一般较小，不适合存放大量的物品。而对于推拉式箱包，其体积较大，存放的物品很多，重量很重，因此，使用方便性就成了该推拉式箱包的考虑重点。Luggage and bags are one of the most commonly used daily necessities. While providing convenient functions for carrying items, they also have obvious characteristics of the times and have obvious fashion characteristics. In order to clearly reflect these characteristics, people are constantly developing and experimenting with various materials, structures, aesthetics and performances used to make bags. Common bags are generally portable or push-pull. For hand luggage, it is more convenient to use, but its volume is generally small, and it is not suitable for storing a large number of items. As for the push-pull luggage, its volume is large, there are many stored items, and the weight is very heavy. Therefore, the convenience of use has become the focus of the push-pull luggage.

但是对于这些推拉式箱包，其主要由箱体、箱盖组成，箱体和箱盖的后面布片缝合或活页连接成一体式结构，而仅有前侧才能打开箱盖。当箱包摆放或存放前侧没有朝向外面时，使用者必须先搬动箱包将箱包调整到前侧朝外才能够顺利打开箱盖，因此导致取放物品不方便。另外，当在旅行时，有时免不了要从箱包里拿东西，如上飞机，坐火车，此时则需要打开箱包，现在的箱包只能平放在地面上拉开拉链，以打开箱包。这明显给用户带来不少的麻烦。However, for these push-pull bags, they are mainly composed of a box body and a box cover. The back cloth pieces of the box body and the box cover are stitched or loose-leafed to form an integrated structure, and only the front side can open the box cover. When the front side of the luggage is not placed or stored, the user must first move the luggage to adjust the front side of the luggage to face outwards, so that the lid can be opened smoothly, which makes it inconvenient to pick up and place items. In addition, when traveling, sometimes it is unavoidable to take things from the luggage, such as getting on a plane or taking a train. At this time, the luggage needs to be opened. Now the luggage can only be placed flat on the ground and zippered to open the luggage. This obviously brings a lot of trouble to the user.

具体实施方式Detailed ways

以下对本发明的具体实施例进行进一步详细说明。应当理解的是，此处对本发明实施例的说明并不用于限定本发明的保护范围。The specific embodiments of the present invention will be described in further detail below. It should be understood that the descriptions of the embodiments of the present invention herein are not intended to limit the protection scope of the present invention.

如图1至图4所示，其为本发明提供的一种四边开合的箱包的结构示意图。所述四边开合的箱包包括一个箱体10，一条设置在所述箱体10上的拉锁组件20，以及两个设置在所述拉锁组件20上的止齿部30。可以想到的是，所述四边开合的箱包还包括其他的功能模块，如拉手，拉杆组件，滑轮组件等等，其为本领域技术人员所习知的技术，在此不再一一详细说明。As shown in FIG. 1 to FIG. 4 , which are schematic structural diagrams of a four-sided opening and closing luggage provided by the present invention. The four-sided opening and closing luggage includes a box body 10 , a zipper assembly 20 disposed on the box body 10 , and two tooth-stopping portions 30 disposed on the zipper assembly 20 . It is conceivable that the four-sided opening and closing luggage also includes other functional modules, such as handles, pull rod assemblies, pulley assemblies, etc., which are technologies known to those skilled in the art, and will not be described in detail here. .

所述箱体10可以为由塑料热塑成型、或者是布质车缝成型的盒状结构，其具体地，所述箱体10可以为拉杆箱，也可以双肩包或单肩包，还可以为其他类型的包，等等。所述箱体10包括相互扣合的一个上盖11与一个下盖12。所述上盖11与下盖12具有基本相同的结构，当该上盖11与下盖12扣合在一起时，则形成一个空间以用于让用户收纳物品。The box body 10 may be a box-shaped structure formed by plastic thermoplastics or cloth sewing. Specifically, the box body 10 may be a trolley case, a backpack or a shoulder bag, or a for other types of packages, etc. The box body 10 includes an upper cover 11 and a lower cover 12 that are fastened to each other. The upper cover 11 and the lower cover 12 have basically the same structure. When the upper cover 11 and the lower cover 12 are fastened together, a space is formed for the user to store items.

所述拉锁组件20包括一个双层拉链21，两个分别设置在所述双层拉链21上的拉头22，以及两个设置在所述双层拉链21上的插棒23。所述双层拉链21为一种防爆拉链，这使得当该双层拉链21拉合后，无论用什么锐器，在不破坏该双层拉链21的前提下都无法打开该箱包，使得该箱包可以四边开合成为可能。因为对于设置有单层拉链的箱包，经过大量的实验可以证实，只要使用尖锐的硬物即可以拉开拉链。这使得单层拉链不适用于360开合，因为只要被戳开单层拉链，整个箱子便被完全打开了。所述双层拉链21本身为一种现有技术，如专利号为201220248939.6，专利名称为一种单头双层拉链所公开的技术，在此不再详细说明其结构与工作原理，具体地，所述双层拉链21包括一条车缝在上盖11上的上链条211，以及一条车缝在所述下盖12上的下链条212。两个所述拉头22具有相同的结构，其具体结构已被专利号为201220248939.6的专利公开，在此不再赘述。所述拉头22包括一个脱开侧221，以及一个与该脱开侧221相对的啮合侧222。为了达到四边开合，当两个所述拉头22设置在所述上、下链条211、212上时两个拉头22的脱开侧221相向设置，即组装两个所述拉头22时，所述上、下链条211、212的一端从一个拉头22的脱开侧221***，而从另一个拉头22的啮合侧222***。也从而当两个所述拉头22设置在所述上、下链条211、212上时两个拉头22的啮合侧222相背设置。两个所述插棒23设置有所述上、下链条211、212的同一端，并具有一个锥形结构。所述插棒23可以金属制成，也可以由塑料材料制成。当所述上、下链条211、212的链齿由塑料制成时，所述插棒23的所述锥形结构可以通过烧结形成，即通过火烧或高温热融链齿后，再由一个锥形模具挤压成一个锥形结构。该锥形结构可以为锥台状，也可以为锥尖状。如果插棒23不具有所述锥形结构时，无论是插棒23，还是上、下拉链211、212的端部都为齐平结构，因此当上、下拉链211、212的端部***所述拉头22的啮合侧222时，该齐平结构必将抵顶在拉头22的两片平板的连接柱上，从而阻止所述拉头的啮合侧222组装到该上、下链条211、212上。而由于两个插棒23皆具有该锥形结构，使得上、下链条211、212都可以从所述拉头的啮合侧222***并组装到该双层链条21上。在本实施例中，所述插棒23由金属制成，以利于多次使用，并利于工业制造。因此所述插棒23包括一个本体231，一个设置在所述本体231上的第一切削面232，以及一个设置在所述第一切削面232与本体231的侧面之间的第二切削面233。所述本体231可以为一个管状结构，其套设在所述上、下链条211、212的端部。所述第一切削面232设置在所述本体231的一侧，并为楔形，以利于形成锥形。由于所述第二切削面233设置在所述第一切削面232与本体231的侧面，且该第二切削面233也为楔形，从而形成所述锥形结构。当两个所述插棒23组装到所述上、下链条211、212上时，两个所述插棒23的第一切削面232相向设置，即面对面设置，而两个所述第二切削面233须位于两个所述插棒23的同一侧，以利于所述插棒23***。当组装两个所述拉头22时，两个所述插棒23从一个拉头22的脱开侧221***，而从另一个拉头22的啮合侧222***，从而使两个拉头22相向设置。The zipper assembly 20 includes a double-layer zipper 21 , two sliders 22 respectively arranged on the double-layer zipper 21 , and two insertion rods 23 arranged on the double-layer zipper 21 . The double-layer zipper 21 is an explosion-proof zipper, which makes it impossible to open the bag without destroying the double-layer zipper 21 no matter what kind of sharps are used after the double-layer zipper 21 is closed, so that the bag can not be opened. It is possible to open and combine on four sides. Because for a bag with a single-layer zipper, after a lot of experiments, it can be confirmed that the zipper can be opened as long as a sharp hard object is used. This makes the single-layer zipper unsuitable for 360 closures, because as long as the single-layer zipper is poked, the entire case is fully opened. The double-layer zipper 21 itself is a prior art, for example, the patent number is 201220248939.6, and the patent name is the technology disclosed by a single-head double-layer zipper, and its structure and working principle will not be described in detail here. Specifically, The double-layer zipper 21 includes an upper chain 211 sewn on the upper cover 11 and a lower chain 212 sewn on the lower cover 12 . The two sliders 22 have the same structure, and the specific structure thereof has been disclosed by the patent No. 201220248939.6, which will not be repeated here. The slider 22 includes a disengaging side 221 and an engaging side 222 opposite to the disengaging side 221 . In order to achieve four-side opening and closing, when the two sliders 22 are arranged on the upper and

lower chains

211 and 212, the disengagement sides 221 of the two sliders 22 are arranged opposite to each other, that is, when the two sliders 22 are assembled , one end of the upper and

lower chains

211 and 212 is inserted from the disengagement side 221 of one slider 22 and inserted from the engaging side 222 of the other slider 22 . Therefore, when the two sliders 22 are arranged on the upper and

lower chains

211 and 212, the engaging sides 222 of the two sliders 22 are arranged opposite to each other. The two plungers 23 are provided with the same ends of the upper and

lower chains

211 and 212 and have a tapered structure. The plunger 23 can be made of metal or plastic material. When the sprockets of the upper and

lower chains

211 and 212 are made of plastic, the conical structure of the plunger 23 can be formed by sintering, that is, after the sprockets are heated or melted at high temperature, a cone is formed. The shaped die is extruded into a conical structure. The conical structure may be in the shape of a frustum, or may be in the shape of a conical tip. If the plunger 23 does not have the tapered structure, both the plunger 23 and the ends of the upper and

lower zippers

211 and 212 are flush. Therefore, when the ends of the upper and

lower zippers

211 and 212 are inserted into the When the engaging side 222 of the slider 22 is described, the flush structure will surely abut against the connecting columns of the two flat plates of the slider 22, thereby preventing the engaging side 222 of the slider 22 from being assembled to the upper and

lower chains

211, 212 on. Since the two plungers 23 have the tapered structure, both the upper and

lower chains

211 and 212 can be inserted and assembled to the double-layer chain 21 from the engaging side 222 of the slider. In this embodiment, the plunger 23 is made of metal, which is convenient for multiple use and industrial manufacturing. Therefore, the plunger 23 includes a main body 231 , a first cutting surface 232 disposed on the main body 231 , and a second cutting surface 233 disposed between the first cutting surface 232 and the side surface of the main body 231 . . The body 231 may be a tubular structure, which is sleeved on the ends of the upper and

lower chains

211 and 212 . The first cutting surface 232 is disposed on one side of the body 231 and is wedge-shaped to facilitate forming a cone. Since the second cutting surface 233 is disposed on the side surfaces of the first cutting surface 232 and the main body 231 , and the second cutting surface 233 is also wedge-shaped, the tapered structure is formed. When the two plungers 23 are assembled to the upper and

lower chains

211 and 212, the first cutting surfaces 232 of the two plungers 23 are disposed opposite to each other, that is, face to face, and the two second cutting surfaces The surface 233 must be located on the same side of the two plungers 23 to facilitate the insertion of the plungers 23 . When assembling two of the sliders 22 , the two plungers 23 are inserted from the disengagement side 221 of one slider 22 and inserted from the engagement side 222 of the other slider 22 , so that the two sliders 22 Opposite settings.

所述止齿部30可以由两块软质材料制成，如皮，布，革等。两个所述止齿部30分别设置在所述双层拉链21的两个端部的对接处，具体地，两块所述软质材料分别包覆在所述双层拉链21的两端对接的位置，即将两个插棒23与上、下链条211、212的一端包覆住，并分别车缝在上、下盖11、12上。由于该止齿部30的存在，不仅可以达到美观的作用，还可以阻止两个所述拉头22从所述双层拉链21的两端脱落。进一步地，所述上、下链条211、212的两个端部分别齐平设置，两个所述止齿部30分别设置在所述上、下链条211、212上并分离设置，从而可以实现所述上、下盖11、12在此处打开，从而可以达到任意位置开合的目的。当然，可以想到的是，所述止齿部30还可以由两片金属片制成，其分别设置在所述上、下盖11、12的内外侧，然后用螺钉或铆钉固定。The tooth-stopping portion 30 can be made of two soft materials, such as leather, cloth, leather, and the like. The two tooth-stopping portions 30 are respectively disposed at the butt joints of the two ends of the double-layer zipper 21 . Specifically, two pieces of the soft material are respectively wrapped around the ends of the double-layer zipper 21 for butt joints. position, that is, the two plungers 23 and one end of the upper and

lower chains

211, 212 are covered, and sewn on the upper and

lower covers

11, 12 respectively. Due to the existence of the tooth-stopping portion 30 , not only the aesthetic effect can be achieved, but also the two sliders 22 can be prevented from falling off both ends of the double-layer zipper 21 . Further, the two ends of the upper and

lower chains

211 and 212 are arranged flush with each other, and the two tooth-stopping portions 30 are respectively arranged on the upper and

lower chains

211 and 212 and are arranged separately, so as to realize The upper and

lower covers

11 and 12 are opened here, so that the purpose of opening and closing at any position can be achieved. Of course, it is conceivable that the tooth-stopping portion 30 can also be made of two metal sheets, which are respectively disposed on the inner and outer sides of the upper and

lower covers

11 and 12, and then fixed with screws or rivets.

另外，如现有的箱包，所述四边开合的箱包还包括一个锁具(图未示)，所述锁具设置在所述双层拉链21的两端的对接处的旁边，所述锁具用于与所述拉头22的拉片相锁合，以锁住该箱包，避免被外人有意或无意在未经允许的情况下打开。In addition, like the existing luggage, the four-sided opening and closing luggage further includes a lock (not shown in the figure), the lock is arranged beside the butt joints of the two ends of the double-layer zipper 21, and the lock is used for connecting with the double zipper 21. The pull tabs of the pull head 22 are locked together to lock the luggage and prevent it from being opened intentionally or unintentionally by outsiders without permission.

与现有技术相比，本发明所提供的四边开合的箱包由于具有使用了双层拉链21，其为一种防爆拉链，当其拉合后无论用什么锐器，在不破坏该双层拉链21的前提下都无法打开该箱包，使得该箱包可以四边开合成为可能。而由于双层拉链21的上、下链条211、212的两端分别设置有一个插棒23，该插棒23具有一个锥形结构，该锥形结构与所述上、下链条211、212的另一端相对设置。由于该插棒23的存在，使得两个相向设置的拉头23都可以组装到该双层拉链23上去，即两个所述插棒23从一个拉头22的脱开侧221***，而从另一个拉头22的啮合侧222***，从而可以使得两个拉头22的脱开侧221相向设置，进而使得两个拉头22分别朝相反的方向进行开或合，从而使得两个拉头22除了上、下链条211、212的端部对接的位置可以位于任意位置，进而可以达到四边开合的目的。而由于两个所述插棒23从一个拉头22的脱开侧221***，而从另一个拉头22的啮合侧222***，使得上、下链条211、212的端部对接的位置不再交叠而是一种齐平的状态，这不仅美观，而且可以在该上、下链条211、212的端部对接的位置也可以打开，从而使得该箱包可以任意位置打开。Compared with the prior art, the four-sided opening and closing luggage provided by the present invention is an explosion-proof zipper because of the use of a double-layer zipper 21. Under the premise of the zipper 21, the luggage cannot be opened, so that it is possible to open the luggage from four sides. Since two ends of the upper and

lower chains

211 , 212 of the double-layer zipper 21 are respectively provided with a plunger 23 , the plunger 23 has a tapered structure, and the tapered structure is connected with the upper and

lower chains

211 and 212 . The other end is relatively set.
