Abstract
A kind of box casket of Tape movement closure member has ear shape guide elements and is used for moving in the box body gathering sill.Each ear shape guide elements be designed or net thickness greater than material thickness.This guide can be used in the various plastic box bodies of recording media that are equipped with, and is suitable for record data, sound equipment, video information occasion.
Description
The invention relates to a kind of box casket that has recording medium, especially tape cassete, it has the box spare of a band fenestra, its fenestra can by one movably closure member close or open, this closure member should have at least a guiding projection to move in corresponding at least one groove on box body, the invention still further relates to the closure member of box casket.
Recognize a kind of like this box casket from EP-A-406943.Box body is made of plastics, and described closure member is to be made by extremely thin stainless steel material.Closure member is by punching out or line corrosion and bending forming aborning.In these conventional production runes, sharp edges is unavoidable.Because closure member is to carry out displacement action at box surface, even its trickle unsmooth property also can cause the scratch cell material.
Because known closure member is that the scraping phenomenon occurs in the groove particularly serious by the displacement of leading in box body two grooves of two guiding projections, this will cause the closure member direction of action inaccurate and produce harmful wearing and tearing.
The above-mentioned defective that the objective of the invention is fundamentally to avoid the box casket with closure member to be had.
For a kind of box casket that has recording medium, especially tape cassete, it has the box body of a band fenestra, its fenestra can by one movably closure member close or open, this closure member is moved at least one groove on box body by at least one guiding projection, if make the guiding projection net thickness width of respective grooves no better than, but greater than projection self material thickness, above-mentioned purpose has just realized.
Obtained effect like this like this, promptly kept having reduced the contact point between guiding projection wall and the cell wall under the constant situation of gathering sill width.
In fact, guiding projection can be designed to the bending part of a sheet metal, like this according to the present invention, has alleviated at least because the scraping effect that sharp edges causes.
Guiding projection is made by wear-resistant plastic can be more favourable, therefore also alleviated wearing and tearing at least according to the present invention.
The parts that guiding projection is designed to fillet are suitable, and this helps contacting with cell wall.
In fact, the planimetric map of guiding projection end face may be an arc or waveform.Under any circumstance, contact point is confined to fillet part or wavy projecting point place.Equally the guiding projection side surface is designed to have bossing, especially convex face is useful.
Closure member itself also is a part of the present invention.
This closure member is generally sheet metal spare, and at least one guiding projection is arranged, and is designed to the form of the bending part of sheet metal, and its side is formed with circular arc portion.
In a preferable design, bending sheet metal part end face planimetric map is an arc or waveform.
Closure member also can have a guiding projection of being made by thermoplastics (as polyoxyethylene methylene, polyvinyl fluoride) at least.
In this case, the side direction of this guiding projection has circular arc portion, partly is useful as arc or waveform.
By the only embodiment of explaining property description and explanation the present invention in the accompanying drawing, wherein:
Figure 1A-1C shows the different shape according to guiding projection of the present invention.
Fig. 2 shows sheet metal bending part in the prior art.
Fig. 3 shows to have the bottom plan view of the box casket of guiding projection according to the present invention.
Fig. 3 has shown the back side of the tape cassete box body 20 with a closure member 30 that moves in double-head arrow A direction.One spring 36 is arranged between box body 20 and closure member 30.
Box body 20 has gathering sill 21A and 21B, and wedge-like guiding projection 22A, 22B are wherein arranged, and they are positioned at the back side of closure member 30, are movably.Projection 22A, 22B are sinusoidal shape in Fig. 3, see the planimetric map that is arranged in its end face of groove 21.
Fig. 2 shows a kind of straight guiding projection design that the prior art guiding projection constitutes for the sheet metal bending part, and part 24 stamps out from window 31, and bending is vertical with closure member 30.So as described above, closure member 30 constitutes for sheet-metal plates.
When the following describes according to respectively the designing of guiding projection of the present invention, see Figure 1A-1C, the planar section of closure member 30 all is expressed out in each case, so that provide a direct reference surface, also can be made up of different materials according to this planar section of the present invention.
Figure 1A has shown the guiding projection 32 that is designed to camber, and this can find out with each curve of the dot-and-dash line 34 of top edge 33 and middle longitudinal region.Can so just avoid sharp edges from making this orienting lug 32 by pressing with metallic sheet material, and and the wall of groove 21A and B less surface in contact is arranged.
Width C in this example (at zone line, dot-and-dash line 34 places) is satisfied to concern that C＞B 〉=D, B are the width of top edge 33, and D is a material thickness.Therefore C is the effective width of orienting lug 32, and this width is slightly seen Fig. 3 less than groove width N(), the relation of N＞C＞D has also satisfied like this.
In Fig. 1 C, a kind of remodeling of guiding projection 32 is described, promptly the middle part is straight design, two ends are curve design.The curvature of comparing sweep with the convex design among Fig. 1 is along being constant in the height h scope of guiding projection 35.This switch also can be by pressing or mold formed, and back one method for example is an injection-moulding plastic.
Top edge thickness B among the corresponding Figure 1A of net thickness B1.
Last Figure 1B has provided the guiding projection 37 that has straight design outline known 24 as among Fig. 2, but it is having right cylinder 38 and 39 as circular arc portion by the place, two ends.The most handy injection moulding is produced the part in addition of such right cylinder or analogous shape easily.B2 represents net thickness, and is bigger than material thickness D.In described various structures, have a bit very important, promptly to the small part top edge with respect to each net thickness C or B(Figure 1A), B1(Fig. 1 C) and B2(Figure 1B) should be in middle position.In the example that provides, all meet this condition at the center section of guiding projection longitudinal extent.
In general also can design the guiding projection that there is muscle two sides, be preferably vertical tendon, or the guiding projection of cylindricality, embossment shape protrusion is arranged, with the surface in contact of minimizing and cell wall.
As producing closure member through injection moulding, compression moulding or extrusion with certain thermoplastics, recommend to use anti abrasive as far as possible plastics, as polyacetals class, particularly polyoxyethylene methylene, or the teflon in the fluorohydrocarbon class.
The box casket of band closure member has ear shape guiding projection and is used for moving in the box body gathering sill.Each guiding projection all is designed to net thickness greater than the material actual (real) thickness.
This guiding projection can be used for recording the used plastic casing casket that recording medium and band closure member are housed of occasion as data, sound equipment, image information.
