Abstract

A file utilizing a ring binder subassembly includes an upper member having a longitudinal central axis extending along its length, a pair of hinged leaves supported by the upper member, and a plurality of ring members secured to the hinged leaves for engaging perforations in a document or sheet of paper during use. Such a file folder having laterally spaced elongated ribs extending along the longitudinal axis of the upper member and projecting outwardly therefrom may increase its strength against deformation to prevent or reduce damage to the file folder during shipping, and facilitate packaging and shipping, reducing the space occupied during shipping.

Description

folder

Technical Field: The utility model relates to a file folder, in particular to an improvement to a clamping device used for biting the perforation on the file material page of the file folder.

Background technology: the existing traditional folders in the society are equipped with various rings, which can be opened or closed, and can bite the perforations on the documents or paper material pages in use, so as to clamp the document materials or The purpose of the page. The folder is attached to a cover member by a plurality of fasteners, such as rivets, which extend through the cover member 62 and securely secure the file folder to the cover member, such as by stamping. Such a structure is shown in FIG. 10 .

However, when the traditional folder is assembled with the cover and transported, it occupies a huge volume. The folder can also be shipped unassembled, ie the cover is packaged separately from the folder and subsequently assembled by the user. When packing multiple folders together, one folder can be placed on top of the other so that the ring of the one folder engages the upper part of the other folder. Such a positional relationship is shown in FIGS. 4 , 5 and 9 .

The packaging space that such folders need to occupy during transport is still not optimally reduced, leading to high transport costs and damage to the upper part. Such placement is unstable, with the raised upper part contacting each other causing the ring to slide on the surface of the upper part. This will result in visible scratches on the surface of the upper part due to lateral sliding. In addition, the pressure exerted on the upper part by the rings in contact during transportation deforms the upper part to create a dent, since the upper part of traditional products is usually just a raised and bent metal strip with no structure to prevent this deformation , as shown in Figure 9. As a result of such scratches and dents in transit, the client received the folder with a spoiled appearance and thus unusable. This creates waste as well as lost freight.

Summary of the invention: The technical problem to be solved by this utility model is to provide a folder for the ring clip assembly, which can increase its strength against deformation, prevent or reduce damage to the folder during transportation, and facilitate packaging and transportation, reducing Space taken up in transit.

The purpose of this utility model is to realize by a kind of novel folder. The folder includes: an upper member having a central longitudinal axis extending along its length; a pair of hinged leaves supported by said upper member; onto the hinged leaves so as to snap into corresponding holes on the pages of material held by the folder. The number of rings can be arbitrary, and the arrangement can also be arbitrary, that is, the intervals between the rings can be equal or unequal. There are elongated ribs at transverse intervals, which are arranged on the upper part and extend along the longitudinal axis of the upper part, symmetrically arranged around the longitudinal central axis of the upper part, protruding outward on the upper part, and the ribs may be a first rib extending along the overall length of the upper member, and may further include at least one pair of laterally spaced elongate second ribs projecting outwardly from said upper member and extending along said longitudinal central axis extending in a direction, the second rib is laterally spaced apart from the first rib. Second ribs are provided on opposite longitudinal sides of the ring. A second rib is laterally spaced outwardly from the first rib and is disposed on the upper member. The second ribs are arranged symmetrically about the longitudinal central axis.

Specific implementation method: Embodiment 1: Fig. 1 and Fig. 2 have shown the folder 10 of the product embodiment of the present invention. The folder 10 is secured to a cover piece (not shown).

Folder 10 includes a substantially rigid convexly curved upper panel 12 supporting a pair of hinged hinged leaves 14a, 14b. Secured to the hinged leaves 14a, 14b are a plurality of rings 16 for engaging corresponding holes in the pages of material held by the file folder 10 . Although three rings 16 are shown in FIGS. 1 and 2, it should be understood that any number and arrangement of rings 16 may be used. For example, four rings. The rings 16 may be equally spaced, or may have different spacings.

A handle 18 is located at each end of the convexly curved upper plate 12 for actuating the hinged hinges 14a, 14b to open or close the ring binder in a conventional manner.

The convexly curved upper plate 12 includes a depression 20 near each end thereof. Recess 20 includes an aperture 22 extending through upper plate 12 . In a known manner, posts 24 are used to position file folder 10 above the cover pieces. Posts 24 are inserted into upper plate 12 through holes 22 . The upper portion of post 24 is deformed outwardly to be larger than the diameter of hole 22 , thereby securing post 24 to folder 10 . A rivet (not shown) is then inserted through the hole in the spine of the cover member through the hole in post 24, followed by deformation of the head of the rivet to secure the folder to the cover member, as shown in FIG.

The upper plate 12 includes a pair of first ribs 28 projecting upward and outward from the upper surface of the upper plate 12 . The first rib 28 includes transversely spaced first rib elements 28 a , 28 b arranged symmetrically about a longitudinal axis extending centrally along the length of the upper plate 12 . The first rib 28 is elongated along the length of the upper plate 12 and extends substantially along the entire length of the upper plate 12 from one end to the other.

The upper plate 12 also includes pairs of second ribs 30 located on opposite longitudinal sides of the ring 16 . The number of pairs of second ribs 30 is preferably twice the number of rings 16 . In this embodiment, for three ring members 16, six pairs of second ribs 30 are used.

The second rib 30 protrudes upward and outward from one outer surface of the upper plate 12 . The second rib 30 comprises laterally spaced second rib elements 30a, 30b arranged laterally opposite and preferably laterally outward of the second rib elements 30a, 30b, respectively. The second rib 30 is arranged symmetrically with respect to the longitudinal axis of the upper plate 12 . The second rib 30 is elongated along the length of the upper plate 12 and preferably extends for a length shorter than the length of the first rib 28 . In other words, two short sections of the second rib are provided between each ring 16 , which do not extend from one ring 16 to the other. The length of the second rib 30 is sufficiently long that the ring 16 will contact the rib 30 when deflected when multiple folders are packed as shown in FIG. 5 . However, it is conceivable that the second rib 30 could extend continuously between each ring 16 .

FIG. 3 shows a cross-sectional view through the first and second ribs 28 , 30 . The ribs 28 , 30 are integrally formed as part of the upper part 12 which is deformed during machining to form the ribs 28 , 30 which protrude from the top surface of the upper part 12 .

The location and arrangement of the first and second ribs 28, 30 allow the other file folders to be positioned exactly opposite during package shipment, in which a folder can be positioned directly on top of another file folder, as shown in FIG. 4 . It can also be placed in a staggered manner, that is, the upper folder is placed about halfway between the lower folders, and two or more folders can be placed on top of each other in the shipping package, as shown in the figure 5. The packaging is compact, and the transportation is very safe and convenient.

Embodiment 2: as shown in Fig. 6 and Fig. 7 . The file folder of this embodiment is different from the first embodiment in that the number of rings is different. The folder of the embodiment adopts three circular parts, and the file folder of the present embodiment adopts four ring parts, and other features are the same, and will not be described again.
