Abstract

A ring-type binder suitable to be fixed to book cover by at least one rivet includes a basically rigid curved top plate. A pair of pivoted slender plates is supported by the top plate. More ring parts are installed on the slender plates. Said rivet can be directly matched with book cover and curved top plate.

Description

Ring-type binder

The present invention relates to a kind of ring-type binder, particularly a kind of at least one rivet that is adapted to pass through is fixed in ring-type binder on the base member.

Usually, ring-type binder is fixed on the strip of paper used for sealing by rivet, and this rivet has the head and the deformable afterbody that can cooperate with strip of paper used for sealing, and this afterbody for example can match with cylindrical shell on the upper plate that is fixed to ring-type binder by punching press.

The shortcoming of this traditional ring-type binder is: assembling process is not only wasted the labour but also is made mistakes easily.At first, must offer assembler's rivet, rivet has suitable dimensions and shape, so that be suitable for the hole on cylindrical shell and the corresponding strip of paper used for sealing.When the assembler is fixed in ring-type binder on the strip of paper used for sealing, must at first inserts rivet and make it pass strip of paper used for sealing, then, pass the cylindrical shell in the ring-type binder, make the afterbody distortion of rivet again, for example by punching press, so that it matches with the upper plate of ring-type binder.

Therefore, the objective of the invention is to propose a kind of ring-type binder that can overcome above-mentioned shortcoming.

The present invention proposes a kind of ring-type binder, it is adapted to pass through at least one fixture and is fixed on the base member, this ring-type binder comprises the last structure that is essentially rigidity, should go up the pivotable structure down of support structure, a plurality of annulus elements are installed on this time structure, and wherein, retaining element directly matches with base member, it is characterized in that fixture also directly matches with last structure.The present invention makes becomes possibility like this, and the ring-type binder that promptly offers the assembler is fixed with for example fixture of rivet, like this, and with just cooperating all set of strip of paper used for sealing.Thereby the rivet of different size and/or shape just no longer requires to give the assembler.

Advantageously, fixture can comprise deformable so that the upper end of matching with last structure; What be fit to is that fixture can comprise upright in fact cylindrical shell device, on it comprises.

The last structure of ring-type binder can comprise depression easily, and the upper end of fixture is deformable so that match with this depression.

Fixture can further comprise at least one retaining element, and it is suitable for matching with base member.

Advantageously, the cylindrical shell device can be integrally formed with retaining element.

Compatibly, retaining element can comprise a plurality of fixtures that come to a point in fact downwards, and each all is deformable so that match with base member.

Fixture can advantageously comprise the covering of the fan of arc.

A plurality of fixtures can be easily the periphery in hole from the panel element of fixture overhang downwards, panel element can be suitable for against base member.

Present invention is described by way of example below in conjunction with accompanying drawing.

Fig. 1 represents the decomposition view that has the ring-type binder of strip of paper used for sealing according to of the present invention.

Fig. 2 represents the stereogram of the downside of ring-type binder shown in Figure 1.

In Fig. 3 presentation graphs 1 along the sectional view of the ring-type binder of A-A line.

Fig. 4 A presentation graphs 1 is to the underside perspective view of rivet shown in Figure 3.

The sectional view of the rivet shown in Fig. 4 B presentation graphs 1 to Fig. 4 A.

Fig. 1,2,3 shows according to ring-type binder of the present invention, and it represents with 2 that usually this ring-type binder comprises the upper plate 4 of the bending of rigidity in fact, and it is supporting a pair of elongated board 6a and 6b, and this can move to elongated board capable of pivoting relative to each otherly.Three annulus elements 8 are fixed on elongated board 6a, the 6b.Each end of ring-type binder 2 be handle 10, it for example can outwards be pushed with thumb, thereby acts on the downside of elongated board 6a, 6b, so that open annulus element 8 in a conventional manner.Rivet 14 matches with the depression 12 of the opening of each end of the upper plate 4 of close bending.

As Fig. 4 A, 4B more clearly shown in, rivet 14 comprises cylinder 16, this cylinder 16 has narrower head 18, it can be out of shape so that 12 match with depression by for example punching press.Rivet 14 has flat in fact plate 20, has four holes on this plate.One group of pawl 24 overhangs from the periphery in each hole 22, and this pawl 24 is deformable by pushing for example, so that match with hardboard or plastics (for example PVC) 26.Pawl 24 is extruded from flat in fact plate 20.Cylindrical shell 16, head 18, essence are that flat plate 20 and pawl 24 is all integrally formed, so that strengthen the intensity of rivet 14.

When assembling, flat in fact plate 20 is against the surface in the face of ring-type binder 2 of strip of paper used for sealing 26.This set has strengthened the stability of rivet 14, thereby, also just strengthened the stability of ring-type binder 2 with respect to strip of paper used for sealing 26.
