Description

Compact-disc twin box

The present invention relates to a kind of box, this paper is called compact discs (Compact-Disc) box (hereinafter to be referred as the CD box), this box is used to pack into digital recording disk or CD dish and the thing of the similar plate-like that is made of information recording carrier, for example Digital Television disk, read-only storage CD dish etc.

Since adopting record CD dish or digital recording disk, used and at " Phi-Lips Trch.Rrv.40,1982, No.6, Page180 " in the explanation standardized CD box by constituting with injection molding respectively bottom of lucite and top cover, this bottom and top cover pivotally link together with two gudgeon conjunctions, in addition, the CD box also comprises support plate or the pallet that inserts bottom with press fit.Installed the seizure parts on support plate, these seizure parts are packed in the center pit of record CD dish and it are fixed, and the data side of record CD dish is facing to pallet, but gap therebetween.Insert paper tape between pallet and bottom, the curved end of this paper tape leans against respectively on adjacency and the side wall inner surfaces away from conjunction.Paper tape carries the information that can read of printing by the basal surface of bottom and the forward and backward sidewall of bottom, and a catalogue that can often take out is arranged in top cover.

The CD box of this routine is seen following shortcoming from the viewpoint of producing and handle: the production of box usually and the production of record CD dish not in a place, therefore box must be packed, transport in the record CD dish producer hand record CD dish of packing into subsequently then.Because catalogue must match with record CD dish,, goes catalogue so also can only being inserted in the box in the factory of record of production CD dish.Yet, this means that pallet can not be inserted on the bottom, because also need to insert betwixt catalogue when producing the CD box.In fact, pallet must separate packing with bottom and top cover (producer can utilize its gudgeon that bottom and top cover are combined), and then transports the producer to record CD dish.This record CD dish producer inserts in the catalogue with hand or machine subsequently again, pallet is inserted in the bottom, and will write down CD and coil and slide in the seizure mechanism of pallet.All these mean, will handle bottom and top cover on the one hand.Separate processes pallet again on the other hand, freight volume and reserves are too big, and in addition, for last assembling with fill the CD box, the producer of record CD dish also needs the hand labour of other costliness and extra equipment.

For the user, conventional CD box also has a shortcoming, and promptly box can only hold a slice record CD dish.If in a box, adorn two or more write down CD dish, the present practice is to utilize as European patent publication 0114631 described box, the bottom that two the single disk CD of routine boxes are arranged in this box, each bottom is equipped with the pallet of an insertion, these two bottoms are connected to the middle body of a box-shaped by its gudgeon, so that rotate around two axis.The double thickness that the thickness of this biplate CD box is a bit larger tham conventional box.The box-shaped middle body has central bottom, and this central bottom also has the form of pallet, and the seizure mechanism of the corresponding record CD center hole of packing into is housed in its one or both sides.According to whether have this seizure mechanism at core, this box is suitable for fixing two, 3 or 4 record CD dishes.This dual box also has for the producer and the same shortcoming of above-mentioned monolithic box, and promptly it can only be assembled at last by the producer of record CD dish.In addition, this multi-disc box uses very inconvenient because of its thickness is thick.If only adorn two record CD dishes therein, this is prevailing situation, just then box has comprised a large amount of useless spaces.

German patent publication thing 3414903A relates to the CD box of claim 1 the sort of type as described in the preamble, comprises pallet between the bottom of this box and the top cover, and this pallet also pivotally is connected to bottom and top cover by the gudgeon conjunction.Fixedly a slice or two seizure mechanisms that record CD coils are housed on the one or both sides of pallet.Utilize the rotary action of pallet not only can shed record CD dish, and also have rib, just can touch bottom because upwards separate pallet in catalogue is inserted bottom from a side or the opposite side of pallet.Therefore this known CD box can be assembled by the producer in principle, dress up a producer who supplies with record CD dish, just can when the pallet pivot is in vertical position, in bottom and top cover, insert one or two record CD dish and corresponding catalogue with the producer of hub disk.Therefore simplify box packing and transportation when giving the record CD dish producer, also simplified their dismantlement work.

Under the situation of this known CD box, the notch shape gudgeon eye (gudgeon of the protrusion on the corresponding teat at top cover is encased in this gudgeon eye) that utilization is being processed on bottom and the pallet, though can avoid the phase mutual interference, but the top cover of pallet can only rotate with respect to bottom, and the axis of this notch each other at angle and be positioned on the midplane of closing box.Yet this means, when breakdown, the CD box is easy to damage, and the user is difficult to operation, because the gudgeon in notch is loose, three parts of box, be the position that top cover, pallet and bottom are easy to be in distortion each other, so when closing box, they are easy to block, in some cases, the protuberance and the gudgeon eye of supporting gudgeon may snap.If put two record CD boxes at this known CD box, then can produce other shortcoming, promptly when breakdown CD box, pallet can only touch the record CD box of pallet upside, so in order to shed following record CD dish, must overturn, this is very inconvenient, and work as box breakdown, because above-mentioned notch is easy to cause trouble.

The CD box of this type known does not appear on the market, and corresponding patented claim is also abandoned.

An object of the present invention is to provide a kind of the sort of Type C D box that begins to mention, it can be used for putting one or two record CD box, under the breakdown and the situation of closing, this CD box is quite firm, and can arbitrarily operate one or another record CD box, its size and outward appearance are identical with single-deck CD box on the present market.

Purpose of the present invention can reach by following measure:

A kind of box, the similar plate-like thing that is used for fixing digital recording dish, record CD dish and information recording carrier, its structure is flat rectangular parallelepiped, and this box is made up of bottom, top cover and the pallet that is arranged between them, and these three parts utilize the gudgeon conjunction to turn and linking together.Above-mentioned pallet is equipped with the seizure engaging mechanism in the one side at least, this seizure engaging mechanism medium pore on the record CD dish of packing into, on all four sides of box, on bottom and/or top cover moulding sidewall, when box is closed, this sidewall surrounds pallet basically, this box has a feature in the following characteristics at least: (a) each gudgeon conjunction is made of the gudgeon that is molded on bottom or the top cover, end on it is encased in the circular gudgeon eye on top cover or the bottom, and the center section of gudgeon then is suitable for being enclosed within rapidly the circular gudgeon eye by radially entering notch from side; (b) perpendicular to the sidewall of the bottom of trunnion axis and top cover basically respectively along the whole side edge length of bottom and top cover, the height of sidewall is substantially equal to half of box height when box is closed, when box is closed, sidewall flushes each other, and the joint line between the sidewall is positioned at the central plane of box; (C) on the sidewall of bottom and top cover, be processed with toward each other the breach of configuration in pairs in addition, when box is closed, every pair of breach constitutes corresponding opening respectively, on pallet moulding two clamping plates, this clamping plate extends in opening, so the clamping surface of clamping plate flushes with the outside surface of box wall basically.

Purpose of the present invention can also be expressed by following other measure:

Described box is characterized in that, breach and clamping plate are configured on the narrow limit of box, away from conjunction; Between the corner angle of breach and box, on the lateral surface of narrow sidewall, processed pinch zones, on each clamping plate moulding have a lock rib of two crown stop teats, this crown outshot does not install in the stop notch on the relevant sidewall of top cover and bottom, its feature also is, clamping plate and lock rib are separated with pallet, therebetween across breach or notch, be connected with pallet with tensionally elastic connection rib by having crooked unisexuality with lock rib at the two ends of notch clamping plate, thereby can utilize the engagement of one or two stop protuberance of pressure Shu Songkai of being added on the clamping plate and relevant stop notch.In usual manner, the top cover of CD box has breach in its conjunction one side, this breach is limited by two protuberances that prolong narrow sidewall in the side, on this protuberance, processed the gudgeon eye, at the lobed filling teat of conjunction one side pallet, this filling teat has occupied the breach on the top cover, when box is closed, this filling teat flushes with the top end surface of top cover, conjunction one side at bottom has rear wall, this rear wall is substantially equal to the height of box, but has the seamed edge that the pallet that is contained in above it is filled protuberance, and its feature also is, when box is closed, the gudgeon fitting piece is with respect to the eccentric configuration of the mid-plane of box, therefore when box is opened, the filling rib of pallet just be positioned at the bottom downside below.Its diameter of center section of the gudgeon that cooperates with gudgeon eye on the pallet is bigger than the diameter of gudgeon end parts, and between these two parts, processed shoulder portion, in this box, in conjunction one side along the edge of breach in the inboard moulding of top cover to rib, above-mentioned rib is used for catalogue is placed on top cover, it is characterized in that, at the pallet and the protruding shoulder of having filled transition portion moulding between the protuberance, when box was closed, this shoulder was supporting rib.Trap setting comprises many elasticity lugs that are separated from each other by notch, and is configured on the common plane, and pin is caught in this lug supporting, and this seizure pin protrudes from the plane of pallet, alternately protruding both sides to this plane.

Under the situation of CD box of the present invention, bottom, top cover and pallet are connected with coaxial gudgeon conjunction mutually, without notch, so when these parts forward the position of any needs to, structure is enough firm, and gudgeon conjunction structure makes and can from the side the tray member with gudgeon eye be shifted onto on the gudgeon.Therefore might or at first bottom and pallet be coupled together, and then connect, perhaps at first in the usual way bottom and top cover are connected to each other, insert pallet subsequently, and it is slided on the gudgeon with top cover.Therefore, according to the present invention, the CD box producer can select following dual mode; Perhaps finish the assembling of CD box, give the record CD box producer then, perhaps keep the practice now, the bottom that assembles and top cover as one, are done one with pallet, separately supply with the record CD dish producer, assemble at last by them.

According to the clamping plate of device of the present invention is on the outer narrow limit that is exposed at box, and can be operated, thereby the user can clamp clamping plate with the thumb and the forefinger of a hand, and with another hand only with top cover or only bottom is folded up with pallet and be separated, so that can arbitrarily hold a slice of being bearing on the pallet or a slice record CD dish in addition.If according to claim 3, clamping plate is the elastic retaining device parts on pallet between top cover and bottom simultaneously, advantage especially in this respect then, and this elastic retaining device can utilize the pressure that is applied on the clamping plate to unclamp.

With reference now to accompanying drawing, describes a current implementing example of the present invention in detail.

(parts among this figure have been done sizable simplification) as shown in Figure 1, the CD box is by bottom 1, top cover 2 and pallet 3 or support plate assembly, wherein each all makes one-piece construction with the injection-moulding plastic method, bottom 1 and top cover 2 usefulness lucites are made, and pallet 3 is made of the synthetic resin of band look usually.In order to connect this three parts, it can be rotated each other pivotally, two outwards outstanding gudgeon 5 or fulcrum posts are housed on the sidewall 4 of the inside indentation of bottom 1, the center section 5A of each gudgeon has bigger diameter, and two end portions 5B has less diameter and at the shoulder 5C part integrator that mediates.Radial narrow down enter notch 8 can rapidly slide into processing circular gudgeon eye 6 on the sidewall 7 of pallet 3 of center section 5A by beginning from side.The end parts 5B of gudgeon 5 can be inserted in the relevant circular

gudgeon eye

9,9 processing of this gudgeon eye on the chimb 10 of top cover 2, the extended sidewall of top cover 2 of this chimb 10, the elasticity of flexure of chimb 10 can make these parts slide over rapidly on the gudgeon 5.

The

sidewall

12 and 13 of bottom 1 is parallel to the axis of gudgeon, and the height of these two sidewalls approximates the thickness that CD box thickness deducts a wall.Along perpendicular to the direction of trunnion axis two sidewalls 14 being arranged, the height of this sidewall approximately only be half of CD box thickness, and this sidewall has separately recess 15 at close sidewall 12 away from gudgeon conjunction place.

Also have two sidewalls 17 at the direction top cover 2 perpendicular to trunnion axis, the height of this sidewall approximates half of box thickness, and this sidewall also has two recesses 18 in the part away from conjunction.Positioning salient 19 can be molded on the sidewall 17, so that make the catalogue of insertion be fixed on its position.Away from a side top cover 2 of conjunction without any sidewall, and a lower butt joint rib 21 is only arranged in a side near conjunction, be used for fixing catalogue.Top cover 2 has the breach 22 of the sky that is limited by butt joint rib 21 between the protuberance 10 of lengthening sidewall 17.

Have shortly to two side-prominent edge protuberances 23 perpendicular to the direction pallet 3 in conjunction with axis, this protuberance 23 is interrupted by breach 24 respectively at the middle part, the breach 24 record CD dish that is used to pack into.Near conjunction, edge protuberance 23 broadens, wide wide like that to sidewall 7 with gudgeon eye 6, at the filling rib 25 that a projection is arranged between sidewall 7 on the carriage 3, after closing box (as shown in Figure 2), this filling rib has been filled the breach 22 on top cover 2, and flushes with the outside surface of top cover 2.The sloping portion that combines with pallet 3 at filling rib 25 molds butt joint ladder 26, and when box was closed, this butt joint ladder played supporting role to the butt joint rib 21 of top cover, so that strengthen the butt joint rib.In the centre of pallet 3 trap setting 27 is arranged, this trap setting 27 illustrative only in Fig. 1, in Figure 10 and 11, then its thin portion is illustrated with bigger ratio, it has the seizure pin 28 that the difference of loop configurations is protruded up and down, so that the record CD dish of a correspondence is clamped on the upper surface and lower surface of pallet 3.Otch 29 on the pallet 3 is used for reducing weight, can have jury strut 29A near on its peripheral pallet, so that the record CD that clamping is inserted dish.

On the edge teat 23 of the close breach 24 of pallet 3, processed the outwards outstanding clamping plate 30 of two increasings, this clamping plate be installed on bottom 1 sidewall 14 and top cover 2 sidewalls 17 on

breach

15 and 18 in, the stopper rib 31 that a retracted configuration that is right after is arranged in a side of clamping plate 30, each stopper rib has two stacked crown stop teats 32 in the stopper rib, this stop teat can be enclosed in the recess 33 and 34 on the sidewall of bottom 1 and top cover 2, thereby pallet 3 flexibly is locked on bottom 1 and the top cover 2, shown in Fig. 7 and 8, clamping plate 30 and stopper rib 31 are separated with pallet 3 every a narrow notch 34, and they only are connected with base plate 3 by narrow connection rib 35 in two ends of notch 34.Connect by rib 35 and promptly to have the elasticity of flexure, has the elasticity of torsion again, so applying lateral pressure on clamping plate 30 just can inwardly press clamping plate and stopper rib 31 along the plane that is parallel to pallet 3, also can inwardly press along the direction that favours above-mentioned plane a little, therefore, according to being to leave pallet 3 with bottom 1 or with top cover 2, on clamping plate, apply an eccentricity pressure, one Jie or another stop mechanism are preferentially unclamped, be processed with cutting and arrow on the pallet, thereby hold box easily, indications such as arrow can both be opened box along two kinds of directions, also can replace narrow notch 36 with bigger opening.For example bigger opening can be the part of otch 29.Important is not the shape of opening, but utilizes rib 35 to produce elasticity and supporting clamping plate 30.

Fig. 2 illustrates the CD box of closing, and except filling rib 25 and clamping plate 30 and outer, bottom 1 and top cover 2 are wrapping pallet basically fully, fill outside the rib 25 and are exposed at conjunction one side, and clamping plate 30 flushes with side surface, and can be held the box with breakdown CD.Having on the side surface of clamping plate, the joint line between the

sidewall

14 and 17 of bottom 1 and top cover 2 is basically along the central plane of CD box.

As shown in Figure 3, when breakdown CD box, top cover 2 can rotate at least 180 ℃ with respect to bottom 1, and in addition, pallet 3 can rotate 180 ℃ with respect to bottom 1 or top cover 2.When rotating with respect to bottom, the filling rib 25 of pallet 3 must move through the sidewall 13 near bottom 1 conjunction, and arrives the position below the basal surface of bottom 1 as shown in Figure 7 at last.In order to carry out this rotation, the axis of the gudgeon combination that is made of gudgeon 5 and gudgeon eye 6 is eccentric with respect to the central plane of the CD box of closure, be the basal surface skew of axis to bottom 1, this side-play amount equals to fill the thickness of rib 25 and the essential gap between filling rib 25 and bottom 1 basal surface under Fig. 7 state.

Rotating top cover 2 can breakdown CD box, for making things convenient for this operation, as shown in Figure 3, bottom 1 and top cover 2 separately sidewall 14 ' and 17 ' outside surface on processed respectively groove zone 14 ' and 17 ', have this groove zone just to hold easily and the corresponding parts of clamping.

Fig. 4 to Fig. 6 is a thin portion enlarged drawing, can see the important structure feature that is used for the bound fraction that breakdown CD closes from these figure, and these bound fractions are present in top cover 2(Fig. 4 and 4A respectively), pallet 3(Fig. 5) and bottom 1(Fig. 6 and 6A) on.Shown in Fig. 4 and 4A, the gudgeon eye 9 that is rotatably mounted gudgeon 5 end parts 5B that is molded on the bottom 1 is configured on the protuberance 10 prejudicially.When assembling CD box, once be enclosed within on the gudgeon 5 for the ease of gudgeon eye 9, processed inclined surface 11 on the medial surface of the protuberance 10 below being positioned at gudgeon eye 9.Therefore, the thickness of protuberance 10 has reduced, thereby has played guide effect to gudgeon 5 is pushed gudgeon eye 9.

As shown in Figure 5, eccentric gudgeon eye 6 is arranged also on the sidewall 7 of pallet 3, the diameter of this gudgeon eye is identical with the diameter of the center section 5A of gudgeon 5.For ease of gudgeon 5 is inserted in the gudgeon eye 6, has processed at the downside of gudgeon eye 6 and to have entered notch 8.This notch is narrow towards gudgeon 6 gradual changes then.

The bound fraction of bottom 1 is shown in Fig. 6 and 6A.Gudgeon 5 also is molded on the sidewall 4 prejudicially, can know from Fig. 6 A and see, this sidewall 4 makes gudgeon 5 length be no more than the sidewall 14 of bottom 1, thereby is no more than the CD box that is fully assembled with respect to the sidewall 14 inside indentations of bottom 1, stretches to the outside.

Fig. 7 amplifies the bonded block that is illustrated in assembling CD box afterwards.In the drawings, top cover 2 rotates 180 ° with respect to pallet 3.In addition, also dot in the drawings rotate 180 ° of later pallets 3 ', thereby clearly with figure illustrated the butt joint rib 21 of above-mentioned top cover 2 and pallet 3 ' butt joint ladder 26 ' mating reaction.When closing, height H is the height of whole C D box, also is like this at bound fraction, so the CD box as shown in Figure 2, does not have outshot, and the spring configuration is attractive in appearance, from the angle of preserving, also has practical profile.

The axis of gudgeon is not also in the place of the half-distance of vertical range H, but off-center, to bottom 1 skew.Therefore under the situation that box is opened, the main wall of top cover 2 and the wall of bottom 1 be at sustained height, below the filling rib 25 of pallet ' the be positioned at bottom 1.

Fig. 8 and 9 is illustrated in clamping plate on the pallet 3 30 and the configuration of the stopper rib of stepping back setting 31 of adjoining with bigger ratio.Owing on supporting plate 3, dispose notch 36 and stopper rib 31 in place near clamping plate 30, and has a connection rib 35, so can produce aforesaid effect, be that clamping plate 30 has the elasticity of flexure and two kinds of elasticity of the elasticity of torsion, it is applied suitable pressure, stop protuberance 32 is deviate from from the corresponding recess 33 and 34 of bottom and top cover respectively.

Figure 10 and 11 illustrates aforesaid trap setting 27 with bigger ratio, establishes device and is configured on the pallet 3, and be used for laying record CD and coil in the both sides of pallet 3, and with the fixed upper and lower both sides that are fixed on pallet 3 of CD dish middlely.Trap setting 27 contains many each other by notch 28 radially ' separately and the elasticity lug 28 placed along a central opening of pallet 3.On the end of each lug 28 moulding the seizure pin 28B(of the seizure pin 28A that is directed upwards towards and downward sensing point to vertical angle), each lug 28 alternately supports to a side-prominent seizure pin 28A or to the outstanding seizure pin 28B of opposite side, has the seizure pin 28A and the 28B that catch effect and respectively a slice is write down a side and the opposite side that the CD dish is fixed on pallet 3 so can utilize.Because catching pin is on different lugs, do not damage the seizure engaging mechanism of opposite side so can unclamp the record CD seizure geared assembly of pallet 3 one sides.So just, constituted the bilateral trap setting, simultaneously, because all lugs 28 are at grade, so this bilateral trap setting only accounts for very little space at the thickness direction of box.
