Embodiment

Video class case shown in Fig. 1 to 7 includes a lid part 11, a base section 12, with 12 that be connected with lid part 11 and bottom respectively by a hinges 14, as to have hinged effect spine portion 13.

Be injected with the elastic device 11A of clip shape in lid part 11, in order to clamping pamphlet or the printing loose-leaf relevant with video disc, and 12 li annular flange flange 12A that are injected with four along same circle distribution of base section, circle is the step that a diameter is slightly larger than a video disc outer rim in it.So when video disc was put in box, its outer rim was shelved on this step just.When box was closed, the positive part 11B that a pair of box on the lid part 11 is buckled was engaged among the negative part 12B of the clip on the box base section 12.

This box be with polypropylene or a kind of butadiene and cinnamic multipolymer as material, injection molded with one step of single-piece form, transparent plastic sheeting 18 in the outside surface welding of box then.Like this, between this film 18 and box surface, can insert the printed matter (not showing) of instructions and so on.

What go out at the base section 12 previous step integral molded plastics of box is a video disc device for clamping (expression has video disc among Fig. 6 and Fig. 7), this device comprise one be positioned at circular central that four annular flange flange 12A surround, from base section 12 inwardly protruded elastic arms 15, and video disc that inwardly stretch relative with elastic arm 15 respectively with two ejects arm 17.

Be hemispherical video disc mate from the central part of platform 12a to projecting inward one, its core is empty, as being roughly a Chinese " king " font along overlooking the look projection of sphere of direction, the reverse horizontal component in long limit that is parallel to this box wherein placed in the middle is two above-mentioned elastic arms 15, its two edge oppositely extends out to this hemispherical root position respectively from hemispherical center, the end that makes this two elastic arm 15 be in this place becomes two free ends.In addition, on the outside surface in this hemisphere face or two elastic arms, 15 centres, there are round button part 16, two elastic arms 15 bottom surfaces of protruding a little that the reinforcement that is parallel to this two elastic arms bearing of trend is then arranged.Two 17 on ejection arms and two elastic arms are positioned on the straight line.

Ejecting arm 17 extends from the inside along continuous straight runs of platform 12a at first, upwards stretch out along oblique then like cantilever ground, make both ends become two free ends, spacing between this two free end is substantially equal to the spacing between two elastic arms, 15 free ends, and two width that eject arm 17 equate substantially with two elastic arms 15.The two ejection positions relative with the gap of two elastic arms, 15 both sides, arm 17 both sides also are empty on platform 12a.Therefore, two elastic arms 15 and two eject arm 17 all can be crooked under external force, restores again when external force is eliminated.

See that again Fig. 5 it should be noted that: approach free end on two elastic arms, 15 outside surfaces and respectively have a retaining flange 23 that extends perpendicular to length direction, it is slightly downward-sloping that the xsect of this retaining flange 23 is designed to into its upper surface, and its lower surface then is long narrow surface level.The diameter of the sphere endless belt between 23 times free ends of two retaining flanges of two elastic arms is then less than the internal diameter of video disc center pit.In addition, distance between the free end of this two ejections arm 17 is slightly larger than the hemispherical diameter of two video disc retaining flanges, 23 positions, and two free ends are positioned on the same surface level with two retaining flanges 23 basically, and its free-ended upper limb be one with the parallel surface level of lower surface of the video disc retaining flange 23 of elastic arm 15.

In addition, when two elastic arms 15 are in relaxed state, the footpath is more bigger than the aperture of video disc center pit outside the sphere band that is formed by two elastic arms in hemisphere face, the external diameter of above-mentioned two spherical covering of the fan 16a like Chinese " king " font then and two video disc retaining flanges 23 of two elastic arms with it below the equal diameters of sphere endless belt between the free end, and more smaller than the aperture of the center pit of video disc 25.

The operation of the present invention's video class case is described below in conjunction with Fig. 6 and Fig. 7.By the following description, will have more clearly the advantage of this box and to understand.

For video disc 25 being engaged on the base section 12 of box, will earlier it be made its central aperture video disc mate sphere and on being held on, this moment, video disc 25 promptly was laid on two elastic arms 15 owing to the external diameter of the sphere band that is formed by two elastic arms 15 is more bigger than the external diameter of two spherical covering of the fans.Then, the blank parts around video disc 25 center pits is a little firmly exerted pressure, make it be displaced downwardly to the circular platform 12a of base section 12.Corresponding move makes video disc 25 move down along the sphere belt surface owing to two elastic arms 15 are bent under external force, up to the lower surface malleation of its center bore edges on the upper surface of two video disc retaining flanges 23 of two elastic arms 15.Then continue pressurization on video disc 25, the following table around its center pit and act on acting force on the top slope of two video disc retaining flanges 23 is ordered about two elastic arms 15 and is continued crookedly by ground mutually, makes the center pit of video disc 25 can cross two video disc retaining flanges 23.At this moment, two elastic arms 15 are owing to not being subjected to external force to return to not crooked or unbending basically posture.

When the center pit that is pressed down video disc 25 has just begun on the video disc retaining flange 23 of two elastic arms 15 in the slope slide down, the lower surface of video disc 25 touches the two free-ended top planar end surfaces that eject arms 17 immediately.Gu this is because the two elastic force effects that make progress of ejecting arms 17 make this video disc wholely move down the sensation that process comparatively smoothly and not has any impact what the elastic force that overcomes two elastic arms 15 made that center pit crosses two video disc retaining flanges 23.

When the center pit of video disc 25 is crossed two video disc retaining flanges 23, two eject arms 17 above under the elastic force effect of narrow planar end surface to the lower surface around video disc 25 center pits, make the upper surface of video disc 25 be close to the narrow plane surface in below of two elastic arms 15.Like this, this video disc 25 just is rigidly held on the platform 12a of base section 12.

From box, take out video disc as desire, as long as pinch on hemispherical two elastic arms, 15 outside surfaces position respectively near two video disc retaining flanges 23 with forefinger and thumb, both sides are firmly depressed simultaneously two elastic arms 15 are relatively moved inward then, at this moment, the narrow plane of the below of the video disc retaining flange 23 on two elastic arms 15 radially inwardly slides on the upper surface around the video disc center pit, cross retaining flange 23 up to the center pit of this video disc 25, upwards boosted and be shelved on the banded hemisphere face of two elastic arms 15 by the two two free-ended elastic force that eject arm 17.

Then, as long as the indent between per two flanges from four annular flange flange 12A of both sides on box base section 12, the outer rim that pinches video disc 25 just can be with this video disc jack-up, allows the center pit disengaging planar video disc mate of hemisphere and taking away.

Put it briefly, when video disc 25 desires to be engaged in base and during moving up, video disc 25 is subjected to the support effect of crooked basically ejection arm 17 and is not hit, after video disc 25 engagement, by two position-limiting actions that eject the retaining flange 23 of the elastic force of arms 17 and two elastic arms 15 it is stably held again.When desire was taken out video disc 25, the elastic force that is two ejection arms 17 again was with its jack-up.Therefore, generally speaking, above-mentioned structure was both simple, only need pressurize in elastic arm from both sides with one hand during operation, and need not stress on video disc, so very convenient.And, even in transit, or be not intended at ordinary times to make box above or below or one, when being subjected to external force simultaneously down, video disc is got loose.

Mention in the explanation as Fig. 1-7, end box base section 12, ejection arm 17 and elastic arm 15 can form a globality plastic mould at least, but the most whole disc bearing dish or video class case can a step property moulded piece form.
