Description
本发明是一种采用夹固式扣具和柔性背板的新型活页夹，属于办公用品领域。The invention relates to a novel binder using a clip-type fastener and a flexible backboard, which belongs to the field of office supplies.
目前活页夹都采用单层整片材料一体成型的封皮和内侧铆固式扣具；扣具由环臂、开关和基片构成；环臂与开关连接并由开关统一控制；开关被包裹固定在基片中；基片被铆固在封皮内侧；多采用刚性材料；环臂闭合后与基片一起形成约束活页的闭环(图1-a)。其优点是：各部件间的连接异常牢固；活页容量较大。其缺点是：(1)扣具开合费力且噪音大；(2)强力开关给予环臂的巨大咬合力叠加环臂呈锯齿状的开合端，导致捏合时容易被夹伤手；(3)开关增加了基片厚度，加上环臂高度，致使扣具较高，造成书写时硌手；(4)内置的基片使活页靠近背板部分***，造成页面不平整。At present, the binders all use a single-layer whole piece of material integrally formed cover and inner riveting fastener; the fastener is composed of a ring arm, a switch and a substrate; the ring arm is connected with the switch and is controlled by the switch; the switch is wrapped and fixed in the In the base sheet; the base sheet is riveted on the inside of the cover; rigid materials are mostly used; after the ring arms are closed, they form a closed loop that constrains the leaflet together with the base sheet (Fig. 1-a). The advantages are: the connection between the components is very firm; the loose-leaf capacity is large. The disadvantages are: (1) the buckle is laborious to open and close and the noise is loud; (2) the huge bite force given to the ring arm by the strong switch superimposes the serrated opening and closing end of the ring arm, which makes it easy to pinch the hand when kneading; (3) ) The switch increases the thickness of the substrate, and the height of the ring arm makes the buckle higher, causing the hand to stumble when writing; (4) The built-in substrate makes the loose-leaf near the back plate bulge, causing the page to be uneven.
以日系厂商为主，针对传统活页夹在使用中的上述缺点做出了许多改进：扣具采用了树脂等轻质材料，降低了噪音，提高了安全性。增加环扣数量，分担荷载，缩小尺寸，降低扣具高度，方便书写。设计了更薄更省力的开关，包括抽拉式(国誉，KOKUYO WSG-RUCP)、捏合式(国誉，KOKUYO WSG-RUSP)、铰锁式(满乐文，Maruman KURUFIT)。改变扣具布置(锦宫，King Jim 9855TTE-GS)以避开书写手。Mainly Japanese manufacturers, many improvements have been made in response to the above shortcomings of traditional binders in use: the buckles are made of light materials such as resin, which reduces noise and improves safety. Increase the number of buckles, share the load, reduce the size, reduce the height of the buckle, and facilitate writing. Thinner and more labor-saving switches are designed, including the pull-out type (KOKUYO WSG-RUCP), the pinch type (KOKUYO WSG-RUSP), and the hinged type (Manlewen, Maruman KURUFIT). Changed buckle arrangement (King Jim 9855TTE-GS) to avoid writing hand.
【发明内容】[Content of the invention]
活页夹除了兼有更换活页的便利外，应尽可能向装订本看齐以改善书写体验。传统活页夹导致书写不便的主因是扣具的高度：基片的厚度使活页近背板一侧弯曲而不能保持平整，环臂的高度在活页翻到背面书写时抬高书写手以致硌手。解决的办法包括：降低基片厚度或环臂高度，扣具尤其是环臂部分采用容易受压变形的弹性材料，将扣具布置到避开书写手的位置。本发明的新型活页夹以改善书写体验为主要目标，同时改善活页夹对活页的承载和约束性能。In addition to the convenience of changing loose pages, the binder should be as close to the binding as possible to improve the writing experience. The main reason for the inconvenience of writing in traditional binders is the height of the clasp: the thickness of the base sheet makes the side of the loose-leaf near the backboard bend and cannot be kept flat, and the height of the ring arms raises the writing hand when the loose-leaf is turned to the back for writing. The solutions include: reducing the thickness of the substrate or the height of the ring arm, using elastic materials that are easily deformed under pressure for the buckle, especially the ring arm, and arranging the buckle to a position away from the writing hand. The new binder of the present invention takes improving writing experience as the main goal, and at the same time improves the bearing and restraining performance of the binder on the binder.
扣具一般位于封皮的背板或底板上，将扣具从背板移到底板导致：(1)扣具位置不同，承载方式不同：传统活页夹合夹立放时，闭合的环臂类似两根对接的悬臂梁，活页悬挂在环臂上，其荷载由环臂形变产生的弹力抵消；扣具在背板是双臂远端承载，在底板是单臂近端承载；对悬臂梁而言，近端承载优于远端。不利之处：承载环臂的减少，这可以通过增加环臂对数或提高承载环臂的承载能力来弥补；合夹折叠封皮而成的类矩形截面的长边不利于承担荷载形成的弯矩，可以通过加强活页夹的整体性来克服。(2)解除了扣具对背板选材和宽度上的限制，背板不必因负担扣具而被要求必须具有一定的刚性和宽度。(3)“在面板对应环臂的位置开孔”使环臂可以探出面板使面板与底板的间距不受环臂高度的限制，而仅受限于背板内侧净宽、基片厚度和活页厚度。扣具置于底板和面板对应环臂开孔已被现有档案夹所采用，本发明将以此为改进的起点。The fastener is generally located on the back or bottom plate of the cover. Moving the fastener from the back plate to the bottom plate results in: (1) The location of the fastener is different, and the bearing method is different: when the traditional binder clip is placed upright, the closed loop arm is similar to two. For the cantilever beam connected to the root, the loose leaf is suspended on the ring arm, and its load is offset by the elastic force generated by the deformation of the ring arm; the fastener is carried by the distal end of the two arms on the back plate, and is carried by the proximal end of the single arm on the bottom plate; for the cantilever beam, the close The end bearer is better than the far end. Disadvantages: The reduction of the bearing ring arm, which can be compensated by increasing the number of ring arms or increasing the bearing capacity of the bearing ring arm; the long side of the rectangular-like section formed by the folding and folding of the cover is not conducive to bearing the bending moment formed by the load , which can be overcome by strengthening the integrity of the binder. (2) The restriction on the material selection and width of the back plate by the fastener is lifted, and the back plate is not required to have a certain rigidity and width due to the burden of the fastener. (3) "Open a hole at the position of the panel corresponding to the ring arm", so that the ring arm can protrude out of the panel, so that the distance between the panel and the bottom plate is not limited by the height of the ring arm, but only limited by the inner clear width of the back panel, the thickness of the substrate and the Loose-leaf thickness. The fastener placed on the bottom plate and the panel corresponding to the opening of the ring arm has been adopted by the existing file folder, and the present invention will take this as the starting point of improvement.
合夹立放时，由开关传到开合处的咬合力并没有为承载做出贡献而仅是维持环臂闭合，而维持闭合不需要这么强的力，因此，统一 开关对承载是多余的，对维持闭合则冗余太多，去除可以降低基片厚度。去掉统一开关后，为替代传统的扣具环臂的闭合方式、扣具在封皮上的固定方式，产生了环臂自锁、内外夹固，同时也为扣具单元化创造了条件。When the clamp is placed upright, the occlusal force transmitted from the switch to the opening and closing does not contribute to the load but only maintains the closure of the ring arm, which does not require such a strong force to maintain the closure. Therefore, the unified switch is redundant for the load. , there is too much redundancy for maintaining closure, and removal can reduce the thickness of the substrate. After removing the unified switch, in order to replace the traditional closing method of the buckle arm and the fixing method of the buckle on the cover, the ring arm self-locking and internal and external clamping are produced, and it also creates conditions for the unitization of the buckle.
一、环臂自锁1. Ring arm self-locking
去掉开关后，环臂直接与基片连接(图1-b)，开关闭合被替代为环臂自身锁定机制(简称“环臂自锁”)，包括但不限于柔性搭接、弹性搭接、磁性对接等(图2)。柔性搭接和弹性扣接依靠环臂的形变应力维持闭合，磁性对接靠开合端的磁力维持闭合，这些形式的力相对于统一开关维持闭合的力较弱，这提升了开合的便利性和安全性。After the switch is removed, the ring arm is directly connected to the substrate (Fig. 1-b), and the switch closure is replaced by the ring arm self-locking mechanism (referred to as "ring arm self-locking"), including but not limited to flexible lap, elastic lap, Magnetic docking, etc. (Figure 2). The flexible lap joint and the elastic snap joint are maintained closed by the deformation stress of the ring arm, and the magnetic force of the magnetic joint against the opening and closing ends is maintained closed. safety.
二、内外夹固2. Internal and external clamping
将基片置于底板外侧，通过底板上的预留孔，与内侧的环臂夹紧底板，从而将扣具固定在底板上(简称“夹固”，相应的扣具称为“夹固式扣具”)；夹固的方式包括但不限于卡槽式、螺栓式(图3)：前者靠扣具形变应力夹紧板段，后者靠螺纹间摩擦力限制螺栓位移夹紧板段。Place the substrate on the outside of the bottom plate, and clamp the bottom plate with the inner ring arm through the reserved hole on the bottom plate, so as to fix the fastener on the bottom plate (referred to as "clamping", and the corresponding fastener is called "clamping type"). The clamping method includes but is not limited to slot type and bolt type (Figure 3): the former clamps the plate segment by the deformation stress of the fastener, and the latter clamps the plate segment by limiting the displacement of the bolt by the friction between the threads.
内外夹固使得夹内基片厚度归零，活页可以与底板完全贴合而保持页面平整。同时，夹固改变了活页荷载通过扣具传导至封皮的形式：内侧铆固下，荷载由扣具到封皮的传导集中在若干铆接点上，对接触的封皮形成集中拉力；内外夹固后，荷载由环臂传到基片，再通过基片与封皮的接触面传给封皮，对接触的封皮形成分布压力；以面代点，荷载分布更均匀；封皮抗压能力强于抗拉，承载力提升。作为 反作用力，封皮对扣具也由集中拉力变为分散压力，扣具基片的抗压能力强于抗拉，承载的改善使基片可以更薄。The internal and external clamping makes the thickness of the substrate in the clip return to zero, and the loose leaf can be completely attached to the bottom plate to keep the page flat. At the same time, clamping changes the way that the loose-leaf load is transmitted to the cover through the fastener: under inner riveting, the load transfer from the fastener to the cover is concentrated on several riveting points, forming a concentrated tension on the contacting cover; after inner and outer clamping, The load is transmitted from the ring arm to the substrate, and then transmitted to the cover through the contact surface between the substrate and the cover, forming a distributed pressure on the contacting cover; the surface is used as a point, and the load distribution is more uniform; strength increase. As a reaction force, the cover to the fastener also changes from concentrated tension to distributed pressure, the compression resistance of the fastener substrate is stronger than the tensile strength, and the improvement of the load bearing enables the substrate to be thinner.
三、扣具单元化3. Fastener unitization
去掉开关后，解除了基片作为统一开关的基座而必须保持整体性的限制，这使得扣具可以被划分为若干个相对独立的扣具单元(图4)，每个扣具单元由一对环臂和与之相连的独立基片构成。After the switch is removed, the restriction that the substrate must maintain integrity as the base of the unified switch is lifted, which enables the fastener to be divided into several relatively independent fastener units (Fig. 4), and each fastener unit consists of a A pair of ring arms and an independent substrate connected to it are formed.
扣具单元组成扣具的方式有独立式(单元各自独立)、分组式(数个独立单元合为一组，其基片结成一体，如是数组；极端情况是全部单元都合成为一组)、混合式(包含独立式和分组式的组合)。The way of assembling the clasp unit includes independent type (units are independent of each other), grouping type (several independent units are combined into a group, and their substrates are integrated, such as an array; in extreme cases, all units are combined into a group), Hybrid (including a combination of stand-alone and grouped).
四、柔性背板4. Flexible backplane
扣具置于底板解除了扣具对背板在材质选择上的限制，使背板可以采用柔性材料。柔性背板与底板或面板的连接可以是借助连接媒质(如黏合剂)的拼接式或柔性材料延展的整片式。对于整片式连接，为加强底板或面板刚性，可以采用复层构造。Placing the fastener on the bottom plate relieves the restriction on the material selection of the backplane by the fastener, so that the backplane can be made of flexible materials. The connection of the flexible backplane to the bottom plate or the panel may be a spliced type or a whole piece of flexible material extended by means of a connection medium (such as an adhesive). For one-piece connection, in order to strengthen the rigidity of the bottom plate or panel, a multi-layer structure can be used.
结合面板开孔，当夹内活页厚度不超过背板内侧净宽(合夹时背板内侧宽度扣除了面板和底板厚度后的宽度，是平行的面板和底板内侧间距的最大值)时，柔性背板使面板与底板内侧间距可调并保持与夹内活页厚度相等，这使面板总能与活页保持贴合；同时，也使高出夹内活页的环臂部分可以完全***面板开孔，实现环臂与面板的互锁，这不仅可使面板分担环臂上的负载，也提高了活页夹与夹内活页的整体性(图5)。以得到面板与活页贴合且与环臂互锁的效果为条件，柔性背板的内侧净宽也是夹内活页厚度的最大值。Combined with the opening of the panel, when the thickness of the loose-leaf in the clip does not exceed the net width of the inner side of the back panel (the width of the inner side of the back panel is the width after deducting the thickness of the panel and the bottom panel when the clamp is closed, which is the maximum distance between the inner side of the parallel panel and the bottom panel), the flexibility The back plate makes the distance between the inner side of the panel and the bottom plate adjustable and keeps the same thickness as the loose-leaf in the clip, which makes the panel always keep fit with the loose-leaf; The interlocking of the ring arm and the panel is achieved, which not only allows the panel to share the load on the ring arm, but also improves the integrity of the binder and the binder within the binder (Figure 5). The inner clear width of the flexible backboard is also the maximum value of the thickness of the loose-leaf in the clip, on the condition that the panel is attached to the loose-leaf and interlocked with the ring arm.
只有当夹内活页厚度等于背板内侧净宽时，现有的刚性背板才能取得与柔性背板相同的效果。相较于在背板内侧净宽范围内随活页厚度可调的柔性背板，对活页厚度的限定使得刚性背板成为劣势选项。Existing rigid backplanes can achieve the same effect as flexible backplanes only when the thickness of the loose-leaf in the clip is equal to the net width inside the backplane. Compared with the flexible backplane that can be adjusted with the thickness of the loose-leaf within the inner clear width of the backplane, the restriction on the thickness of the loose-leaf makes the rigid backplane a disadvantageous option.
有益效果：通过采用夹固式扣具和柔性背板，改善了书写体验、约束和承载。Beneficial Effects: Improved writing experience, restraint, and load-carrying through the use of clip-on fasteners and flexible backsheets.
