The specific embodiment

At first referring to Fig. 1, there is shown and be used for the device of clamping one stacker, this device comprises: a substrate 10, a sidewall 12, four vertical part 14 and clamp arms 16 that are stamped out from this substrate.This clamp arm 16 links to each other with crank arm 18; One end of each crank arm runs through this clamp arm 16, and its other end runs through corresponding vertical part 14b and 14d and passes sidewall 12.

Lever 22 also is pivotably mounted on the sidewall 12 by the pin 24 (referring to Fig. 2) in the corresponding hole on the sidewall 12 by means of a hole by this lever 22.Helical spring 20 also is installed on this pin 24, and a helical spring arm 20a embeds under the lever 22, in the hole (not shown) on its another arm 20b embedding clamp arm 16.When lever in the position shown in the figure 1 the time, helical spring 20 is tauted (tension) and compresses clamp arm 16 downwards.Yet when lever 22 unclamped, the tension force in the spring 20 also was released, and clamp arm 16 can be moved up around crank arm 18 paper is taken out or the quires of adding between clamp arm 16 and substrate 10.Fig. 4 demonstrates such stacker.

Lever 22 comprises a ledge (not shown), and this ledge embeds in the slit 30 (referring to Fig. 2) so that lever is kept in the position shown in the figure 1.Yet, because lever 22 made by sheet metal, on its direction shown in can the arrow A in Fig. 1 by transverse curvature so that this ledge is discharged from slit 30, thereby lever can be moved up with the tension force in the retracting spring.

The parts of device are made by the steel that is coated with nickel chromium triangle shown in Fig. 1 to 4.The end 12 of lever has one by plastic material, preferred sponge or elastoplast, and the backing plate of making (pad) 34 is with the comfort that increases this mechanism and prevent that the user from contacting with the direct of metal, and this contact can cause allergic reaction.

Fig. 5 and 6 has shown that the whole end of the lever 22 that acts on except the user is wrapped in the plastics rather than has the backing plate 34, and combines the described mechanism of Fig. 1 to 4 identical mechanism.

Fig. 1 is similar with 7 to Fig. 6 with 8, just demonstrates for the whole end 32 of the lever 22 of user operation to be made by plastic plate.

Fig. 9 to 12 has shown a clipboard, and it has one by bar 38 and the substrate 36 that links to each other pivotly with clamp arm 40.A pair of spring 42 is biased in together to clamp paper (referring to Figure 12) between the two substrate 36 and clamp arm 40.Substrate 36 is fixed on a rigidity or semi-rigid substrate or plate 42 (referring to Figure 12) and goes up to form clipboard.Handle 44 forms an integral body with clamp arm 40 so that can open clamp arm 40 paper is added or the taking-up clipboard.The parts 46 of the handle 44 of user's operation are formed by a plastic mattress 46.

The device of Figure 13 to 16 is similar to Fig. 9's to 12, and just its handle 44 is formed on the anterior of this mechanism rather than resembles and is formed on the rear portion shown in Figure 9; Also have one be not both clamp arm 40 between itself and substrate 36, clamp paper rather than resemble shown in Fig. 9 to 12 between clamp arm and plate 42 the clamping paper.

Handle among Figure 13 has one and covers sheet metal 45 and with plastics packet header (tag) (referring to Figure 14) of its encapsulation.

Figure 21 and 22 has shown another clipboard device, and it comprises a substrate 50, and this substrate has by rivet or screw (not shown) and is fixed to a plate, and plate 42 is as shown in figure 12 gone up used hole 51.Clamp arm 52 is pivotably connected on the substrate 50 by bar 54.Clamp arm 52 is by spring 56 (referring to a Figure 21) biased downward (shown in Figure 21 (a)).By pushing handle 57, clamp arm can upwards be risen paper is added or the taking-up clipboard.The edge of handle 57 is formed to prevent that the user from contacting with the metal of handle 57 by plastic mattress 58.The device of Figure 23 to 26 with combine Figure 21 and 22 described devices are similar, just done some changes slightly that from figure, can obviously find out.

Another possibility of mechanism shown in Figure 21 and 22 is shown in Figure 27 to 30, and wherein the whole end of handle 57 is covered by plastic material 58.Figure 31 to 34 is corresponding with Figure 27 to 30, just has the design of improvement slightly, and the design of this improvement can obviously be found out from figure.

Figure 35 to 38 has shown the another distortion of the device of Figure 21 and 22, and just backing plate 58 has only covered the part of handle 57 upper surfaces.

Referring now to Figure 39 to 42,, there is shown the another clipboard mechanism 60 that is fixed on a rigidity or semi-rigid plate 62 (referring to Figure 42).This mechanism 60 comprises a substrate 63, and by rivet or screw (not shown) being passed the hole 64 on this substrate, this substrate can be fixed on the plate 62.

Clamp arm 65 is placed in the spring 66 that covers in 67 towards substrate 63 biasings, and this lid 67 is to form by a section of substrate 63 is turned.One stacker can be sandwiched between lever arm 65 and the substrate 63 (referring to Figure 42).Yet by the clamp arm 65 (as shown in figure 39) that moves up, paper can be added into or take out quires, and this can finish by upwards spurring a handle that is formed by the median rise section 68 of clamp arm 65.The handle section 68 of this protuberance is covered by plastic bushing 69.

Figure 43 to 46 shown a kind of be used for being fixed on a stacker 71 on the plate 72 or be fixed in the file device 70 (a) referring to Figure 46.

Mechanism 70 comprises a substrate 73 (referring to Figure 46) that is provided with three columns 74 that engage with the hole of the paper edge of quires 71." L " shape segmentation wall 75 links to each other with this substrate 73 pivotly by linkage 76; One helical spring 77 L shaped segmentation walls 75 of biasing and away from substrate 73, shown in the arrow B among Figure 43 a.Three otch 78 of one row are arranged at the edge of wall 75, and a slide plate 79 is remained on the upper surface of wall 75 by numeral 80.Slide plate 79 can be in the direction of arrow C along the longitudinal sliding motion of wall 75, and this will be described further herein.Handle 81 can be formed by the upright projection 82 of slide plate 79 ends with this slide plate that moves around; Projection 82 is by vinyl cover 83 parcels (referring to Figure 43 b).Slide plate 79 move through projection 83 in slit 84 joint and be restricted (referring to Figure 44).
