The specific embodiment
Fig. 1 to Fig. 8 has shown that this annular loose-leaf mechanism is generally designated as 10 according to the various views of the annular loose-leaf mechanism of an embodiment of the present utility model.Annular loose-leaf mechanism 10 has upper shell 12, and described upper shell 12 supports a pair of plate 14, and this a pair of plate 14 is mutually hinged so that carry out relative pivot rotation.
Three semi-circular rings 16 all are installed on each plate 14.Each of annular loose-leaf mechanism 10 vertically end is connected with action bars 18 respectively.Action bars 18 can be with respect to housing 12 and the rotation of plate 14 pivots, so that optionally make the pivot rotation between closure state and open mode of described a pair of plate 14.When described a pair of plate 14 is in closure state, the surperficial subtend towards housing 12 of described a pair of plate 14 forms the angle less than 180 °, thereby the free end that makes this three couple half annular ring 16 cooperatively interacts and contacts, to form three pairs of closed loops (extremely shown in Figure 8 as Fig. 1).When described a pair of plate 14 was in open mode, the surperficial subtend towards housing 12 of described a pair of plate 14 formed the angle greater than 180 °, thereby the free end of this three couple half annular ring 16 is no longer contacted with each other, to open ring.
Certainly, well known to a person skilled in the art to be, can open or closure by the free end separation or the close ring that makes that firmly make semi-circular ring 16, thereby omit action bars 18.
As shown in figures 1 and 3, each of housing 12 vertically is provided with the recessed district 19 that has through hole 20 near the end.Can be clear that more that by Fig. 4 each described through hole 20 has the centre bore 22 of circular and the recess 24 that distributes with four equal angles of these centre bore 22 adjacency.Each described recess 24 has external curve edge 24a, this external curve edge 24a and two straight sides edge 24b adjacency.Described two straight sides edge 24b subtends form 50 ° of angles.By this arrangement, form the tongue spare 26 that four equal angles distribute around the centre bore 22 of each through hole 20.These tongue spares 26 are connected with rivet (being also referred to as " eyelet (eyelet) "), are used for annular loose-leaf mechanism 10 is connected with shrouding, and this will discuss hereinafter.
It can also be seen that from Fig. 5 and Fig. 8 housing 12 has the side plate 28 of two side direction of dangling from this housing 12.
Fig. 9 to Figure 14 has shown the various views of the housing 12 of annular loose-leaf mechanism 10.
As shown in figure 15, paper-retaining device (as box type file or file gripping member) may form by annular loose-leaf mechanism 10 is installed on the plate base (for example shrouding 30).Shrouding 30 can be made by cardboard, plastics, metal, metal alloy or these combinations of materials.Shrouding 30 comprises center ridge 32, and a side of this center ridge 32 is connected with preceding shrouding 34, and opposite side is connected with back shrouding 36.Annular then loose-leaf mechanism 10 is installed on the interior first type surface 40 of back shrouding 36 by two rivets 38.So the paper-retaining device that forms such as Figure 16 are to shown in Figure 20.
As can be seen from Figure 21, each through hole 20 only is connected with shrouding 30 by rivet 38.Rivet 38 passes shrouding 30 in the following manner, that is, vertical the 42 outer first type surface 44 with back shrouding 36 of rivet 38 contacts, and described outer first type surface 44 is opposite with described interior first type surface 40.Rivet 38 also passes the hole of aiming at through hole 20 46, and this hole 46 is formed between the hinged a pair of plate 14.The vertical end of going up of rivet 38 is out of shape, to engage with the upper surface 48 of housing 12 around through hole 20.Particularly, the vertical end of going up of the distortion of rivet 38 engages with tongue spare 26 around through hole 20.
As can be seen from Figure 21, when annular loose-leaf mechanism 10 was installed on the shrouding 30, side plate 28 was along inner surface 40 adjacency of the back shrouding 36 of the whole length of side plate 28 and shrouding 30, thereby strengthened the stability of annular loose-leaf mechanism 10 with respect to shrouding 30.Should be noted that the effective depth h that is positioned at the side plate 28 of shrouding 30 tops makes the pivot rotation of action bars 18 can not be subjected to the obstruction of shrouding 30.
As shown in figure 22, when needs are dismantled paper-retaining device by pull down annular loose-leaf mechanism 10 from shrouding 30, screwdriver 50 can be inserted into annular loose-leaf mechanism 10 and and the shrouding 30 of a vertical end adjacency of annular loose-leaf mechanism 10 between.Screwdriver 50 is rotated along arrow F direction pivot, thereby the vertical end of going up of the distortion of rivet 38 is separated with through hole 20 one or two tongue spare 26 on every side, thereby a vertical end of annular loose-leaf mechanism 10 can separate with rivet 38, as shown in figure 23.More specifically, by above operation, the space of holding between the straight sides edge 24b that slips over the external curve edge 24a of two radially relative recesses 24 and be adjacent is indulged in going up of the distortion of rivet 38, and described recess 24 roughly is positioned on the center line of housing 12.Can use screwdriver 50 that another vertical end of annular loose-leaf mechanism 10 is separated with shrouding 30 by same method.
Compare with previous annular loose-leaf mechanism, an advantage of the present utility model is, even annular loose-leaf of the present utility model mechanism 10 does not use barrier part (barrel) can firmly be connected with shrouding 30 yet.Another advantage is, when must and need, can be relatively easily annular loose-leaf mechanism 10 be disassembled from shrouding 30.These two advantages make annular loose-leaf of the present utility model mechanism 10 environmental friendliness, be easy to make, thereby make with low cost.
It should be understood that above only to have described and to implement embodiment of the present utility model, under the prerequisite that does not break away from the utility model purport, can carry out various modifications or replacement it.Should also be understood that the various features of describing for simplicity and in one embodiment in the utility model, also can provide respectively or provide in any suitable inferior mode that makes up.
