The specific embodiment
Preferred implementation of the present invention (being designated hereinafter simply as " embodiment ") is described below with reference to accompanying drawings.
Fig. 1 represents the embodiment according to the application of the compressed wood product of first embodiment of the invention, more particularly, Fig. 1 is the stereogram of the external structure of a digital camera, and this digital camera is covered by the cover piece that is formed by the compressed wood product according to first embodiment.Digital camera 100 shown in Fig. 1 comprises that image pickup units 101 with imaging len, flash lamp 102, shutter release button 103 and two are all as the cover piece 1 and 2 of exterior part.In digital camera 100, accommodate various electronic components and optical element (not shown) to realize the function of digital camera 100.The element that is held for example be the control circuit of carrying out the driving control relevant with image pickup process etc., such as the solid state image sensing device of charge-coupled device (CCD) or complementary metal oxide semiconductors (CMOS) (CMOS) camera module, such as the audio frequency input/output device of microphone or loudspeaker and under described control circuit control the drive circuit of each function element of driving.
Fig. 2 is the stereogram of the signal structure of expression cover piece 1, and this cover piece 1 covers the front side (one side of object-oriented thing when photographic images) of digital camera 100.Fig. 3 is that the line A-A along Fig. 2 cuts open the cutaway view of getting.Fig. 1 to the cover piece 1 that forms by compressed wood product shown in Figure 3 comprise basic for the main board portion 1a of rectangle, in the mode that forms predetermined angular with main board portion 1a along two side plate 1b of the longitudinal direction extension of main board portion 1a and forming two the side plate 1cs of the mode of predetermined angular along the horizontal direction extension of main board portion 1a with main board portion 1a, and this cover piece 1 roughly is bowl shape.
The cover piece 2 that covers the rear side (when photographic images towards cameraman a side) of digital camera 100 has and cover piece 1 essentially identical shape.Similar with cover piece 1, cover piece 2 has suitable opening and notch, to expose the necessary element that is contained in the digital camera 100.For example, cover piece 2 has semi-circular cut-out portion, and this semi-circular cut-out portion has the shape identical with notch 14 and is formed on the position corresponding with notch 14.When for assembling digital camera 100 cover piece 1 and 2 being bonded together, the notch 14 of the notch of cover piece 2 and cover piece 1 is bonded together and is formed for exposing the opening of shutter release button 103.
Except above-mentioned those openings and notch, cover piece 1 or 2 also can have other opening and notch.For example, cover piece 1 or 2 can have the opening that is used for attached view finder, be used to expose the user in order to the opening of the input button that provides operation instruction signal, expose the opening or the notch of the connecting interface (for example DC input terminal or USB splicing ear) that is used for external device (ED).In addition, cover piece 1 or 2 can also have the audio frequency delivery outlet, can hear from the sound that is embedded in the loudspeaker in the digital camera 100 by this delivery outlet.
Method according to the converted timber of first embodiment will be described below.At first, cut out wood piece 41 (cutting processing) from unpressed log.The wood piece that cuts out is the raw material that are used for cover piece 1.The volume of the volume ratio finished piece(s) of the wood piece that cuts out is big, the amount of the amount that goes out greatly for reducing in the compression process process of describing after a while.The log that adopts can be selected from multiple timber type according to the purposes of cover piece 1, for example Japanese cypress, Chinese juniper cdear (hiba cedar), paulownia, Japanese cedar, pine, cherry, beech, ebony, bamboo, teak, mahogany and redwood.
The wood piece that cuts out can have straight burr surface, plain weave surface, middle texture or end grain surface between straight burr and plain weave, and can select best textured pattern according to the purposes of compressed wood product.Therefore, the textured pattern of wood piece is not shown in the drawings especially.
After cutting processing, the wood piece that cuts out is compressed (compression process).In compression process, wood piece is retained in next predetermined amount of time of water vapor of HTHP, make wood piece absorb excess water and soften.Here, high temperature is meant that temperature is 100 ℃ to 230 ℃, more preferably about 180 ℃ to 200 ℃, and high pressure is meant that pressure is 0.1MPa to 3MPa (megapascal (MPa)), more preferably about 0.45MPa to 2.5MPa.Optionally, can heat wood piece 41 by the frequency electromagnetic waves that applies such as microwave, rather than as mentioned above it is retained under the water vapor.
Afterwards, with wood piece be placed on the softening identical water vapor that is adopted under, and it is clamped between the pair of metal mould, make it be subjected to the pressure of scheduled volume.Fig. 4 schematically shows this compression process.In Fig. 4, be used for having projection 52 from the metal die 51 that last direction wood piece 41 is exerted pressure, the inner surface that this projection 52 is configured as with wood piece 41 is complementary.The inner surface of wood piece 41 is from main board portion 41a extension and be bent to side plate 41b and 41c respectively.From the floor lift one Frusto-conical protuberance 53 of projection 52, shown in the stereogram of Fig. 5.Metal die 51 shown in Fig. 4 that Fig. 5 represents to reverse.The line B-B of Fig. 5 (this line passes protuberance 53 on the direction that is parallel to the x axle) is identical with the line B-B of Fig. 4.
Fig. 6 is that the line B-B along Fig. 4 cuts open the cutaway view of getting.As shown in Figure 6, the radius of curvature of inner surface that extends to the bend 41ac of side plate 41c as the main board portion 41a from wood piece 41 is expressed as RI, and when the radius of curvature of the curved surface of the projection 52 of bend 41ac is expressed as RA, then sets up the relation of RI＞RA.
On the other hand, being used among Fig. 4 or Fig. 6 has recess 62 from the metal die 61 that following direction wood piece 41 is exerted pressure, and the crooked outer surface that this recess 62 is configured as with wood piece 41 is complementary.This outer surface is from main board portion 41a extension and be bent to side plate 41b and 41c respectively.When the radius of curvature of the outer surface of the bend 41ac of wood piece 41 is expressed as RO, and when the radius of curvature of the curved surface of the recess 62 of the outer surface of bend 41ac is expressed as RB, then set up the relation of RO＞RB.
When along cuing open the cross section of getting perpendicular to line B-B and passing the cross section of main board portion 41a, side plate 41b and protuberance 53 along Fig. 4, observe metal die 51 and 61 and when being placed on wood piece 41 between metal die 51 and 61 from+x direction towards-x direction, as can be seen, metal die 51 and 61 shape and they are with respect to the position of wood piece 41 basic identical with shown in Fig. 6 except size is different.Here, the radius of curvature of inner surface of bend that extends to side plate 41b from main board portion 41a is greater than the radius of curvature against the curved surface of the metal die 51 of this inner surface, and the radius of curvature of outer surface of bend that extends to side plate 41b from main board portion 41a is greater than the radius of curvature against the curved surface of the metal die 61 of outer surface.
Fig. 7 is the vertical sectional view along cross section same as shown in Figure 6, and expression is by the wood piece 41 of metal die 51 and 61 clampings and compression (being in the state that the distortion of wood piece 41 has almost finished).As shown in Figure 7, wood piece 41 be deformed into by compression and metal die 51 and 61 between the corresponding 3D shape of spatial form.When wood piece 41 was compressed, compression ratio changed in main board portion 41a, and in the part of protuberance 53 than the height in the other parts.In the first embodiment, the compression ratio in being highlighted portion's 53 compressed portion (that is, the ratio owing to the thickness deltat R that reduces of compression and compression thickness R before is expressed as Δ R/R) is at least 0.75, and more preferably at least 0.80.As a result, the proportion of compression section is about 1.4, and this approaches the proportion 1.5 of the material of the cell membrane in the general timber.Here, the scope of described compression ratio is 0≤(Δ R/R)＜1.
Be well known that about 1.5 the time when becoming up to its proportion at the water vapor lower compression wood piece of HTHP as mentioned above, the characteristic of wood piece changes.Under this condition, wood piece has lost the inherent characteristic of timber.For example, textured pattern disappears, and wood piece by fluidization (for example, referring to Kitazawa, Kitamura, Shibuya, and Kojima, " Phenomenon ofPermanent Fixation of Compressed Cedar Obtained by Consolidation nearlyto Limit ", 21th Annual Convention Proceedings, Wood TechnologicalAssociation of Japan, 2003).When wood piece stood this variation by compression, its fundamental transformation became to show as the tone of tortoise plastron and the resin of transmitted light.Therefore, can have the Wood products of translucent portion with the manufacturing of a slice timber, and need not as conventional art, to use independent transparent component.
After wood piece 41 is retained in next predetermined amount of time of state shown in Figure 7, metal die 51 and 61 is separated from each other to discharge wood piece 41 from compression.Remove water vapor then and make wood piece 41 dryings.Like this, just finished the original form of cover piece 1.Since compression process, the thickness r of main board portion 41a
1On the whole zone except thin portion 11, all become roughly even.Main board portion 41a is the compression ratio C on thickness direction except thin portion 11
1=(R-r
1)/R is about 0.40 to 0.70, more preferably about 0.50 to 0.70.
For the sake of clarity, provide the example of occurrence.Thickness R before main board portion 41a compression is 3.2mm, and the thickness r after the main board portion 41a compression
1During for 1.6mm, the compression ratio C of main board portion 41a except thin portion 11
1Be 0.5.On the other hand, as the thickness r that approaches portion 11
2Be 0.80mm, then the compression ratio C of thin portion 11
2=(R-r
2)/R is 0.75.When further compressing in the scope of the intensity that can not damage wood piece, the thickness of thin portion 11 can further be reduced to about 0.40mm to 0.50mm, with the transparency of the thin portion 11 of further enhancing.Optionally, in order to strengthen transparency, can just form the part that will be processed to thin portion 11 in beginning, make this part thinner than the other parts of main board portion, and compression process can be controlled to the compression ratio that makes in the thin portion and be at least 0.75, more preferably at least 0.80.
In above-mentioned compression process, at least one in the suitable driver element incoming call driving metal die 51 and 61 can be set, to realize the vertical relative motion of metal die 51 and 61.Optionally, metal die 51 and 61 can be screwed together each other, makes the vertical relative motion of metal die 51 and 61 to realize by manually or automatically screwing.
Except digital camera, the shell that also can be used as other electronic equipment according to the compressed wood product of first embodiment, for example, the remote control and the digital VTR of the electronic equipment such as the mobile terminals of portable phone, personal handyphone system (PHS) and PDA(Personal Digital Assistant), portable audio, IC logger, portable television, portable radio, various household electrical appliance.When adopting the compressed wood product conduct to be used for the shell of small portable electronic device as listed above, the thickness setting after preferably will compressing is about 1.6mm.When luminescent device is arranged in this electronic equipment, make that the light that sends from such device can be transmitted to the outside, and need not to use independent transparent component when this luminescent device was sitting in the thin portion.
According to above-mentioned first embodiment, be used to make wood piece to be deformed into the compression process that predetermined three-dimensional shape is carried out owing to having controlled, make that the compression ratio at thickness direction be at least 0.75 in the thin portion, therefore can be, promptly approach portion and give semi-transparency property for the part of wood piece.So even when Wood products need have translucent portion, procedure of processing that also can be by still less is with the such Wood products of less components manufacturing.Thereby can provide the method and the compressed wood product of more economical converted timber.
And, according to first embodiment,, therefore compare with the product that forms by the member that separates because translucent portion and other parts are formed by same material, can strengthen the airtight quality of compressed wood product.When adopting such compressed wood product conduct to be used for the shell of electronic equipment, can prevent moisture intrusion electronic equipment by the capillarity between the dividing member.
Fig. 8 is the upward view of the structure of the metal die that uses in the method that is illustrated in according to the converted timber of second embodiment of the invention.Fig. 9 is that the line C-C along Fig. 8 of metal die cuts open the vertical sectional view of getting.In Fig. 9, metal die is arranged such that in Fig. 8 coordinate+the z direction is corresponding with the direction vertically upward among Fig. 9.In second embodiment, the wood piece that is obtained by unprocessed log is as the wood piece 41 in first embodiment.The shape of the compressed wood product that will make by compression and the shape of cover piece 1 are roughly the same, and adopt this Wood products as the shell that is used for digital camera.
Fig. 8 and metal die 71 shown in Figure 9 have projection 72, and this projection 72 is configured as and the extending and the inner surface that bends to side plate 41b and 41c is complementary from main board portion 41a of wood piece 41.Two protuberances 73 stretch out downwards from the bottom of projection 72.Protuberance 73 has: star bottom 73a; Outer rim 73b, this outer rim 73b has the star shape similar to the shape of bottom 73a, and has the size bigger than bottom 73a, and forms the bottom surface of projection 72 and the border between the protuberance 73; And inclined-plane 73c, this inclined-plane 73c extends and forms mild curved surface between bottom 73a and outer rim 73b.
Figure 10 is the stereogram of the structure of the cover piece that formed by the compressed wood products that form of compression by metal die 71 and 61.Figure 11 is that the line D-D along Figure 10 cuts open the cutaway view of getting.Figure 10 and cover piece shown in Figure 11 3 are similar with cover piece 1, two side plate 3b that comprise the main board portion 3a of essentially rectangular, extend in the mode that forms predetermined angular with main board portion 3a along the longitudinal direction of main board portion 3a and two side plate 3c that extend along the horizontal direction of main board portion 3a in the mode that forms predetermined angular with main board portion 3a, and this cover piece has roughly bowl shape.
The part of wood piece is against the protuberance 73 of metal die 71, and is compressed between the recess 62 of the protuberance 73 of metal die 71 and metal die 61, thereby becomes the thin portion 31 with the thin portion 11 similar transmitted lights of first embodiment.In second embodiment, because the inclined-plane 73c that is formed on the protuberance 73 in the metal die 71 has formed mild curved surface, therefore, the inclined-plane 31c that the thinnest bottom 31a extends to outer rim 31b from thin portion 31 is thickening gradually.Thereby the compression ratio of the thin portion 31 among the main board portion 3a is the highest in the 31a of bottom, and reduces gradually towards outer rim 31b.Specifically, the compression ratio of this bottom 31a is at least 0.75, more preferably at least 0.80, and the compression ratio of the other parts among the compression ratio of outer rim 31b and the main board portion 41a is similar, and also be about 0.40 to 0.70, and more preferably about 0.50 to 0.70.
When light incided in the thin portion 31 with above-mentioned structure, the light of transmission changed its tone gradually from bottom 31a to outer rim 31b.For example, light transmission is the highest in the thinnest bottom 31a, and reduces gradually towards outer rim 31b; In other words, the light of transmission dies down towards outer rim 31b gradually from bottom 31a.The variation of light transmission with produce by compression and brought trickle level for the mulle of thin portion 31 according to the combination as the variation of the tone of tortoise plastron of varied in thickness.The temperature and pressure of the water vapor that adopts during by the control compression can be realized various types of levels, and this further provides specific characteristic for each compressed wood product.
Second embodiment is characterised in that, carries out timber processing like this, even make that becoming the part of similar resin state by compression exists in the identical product side by side with also keep wooden part by compression, has the more product of somewhat complex design thereby can provide.Therefore, in second embodiment, the part of similar resin does not need the same big transparency with the thin portion of first embodiment.Thereby the bottom 31a of cover piece 3 needn't be thin as the thin portion 11 of cover piece 1.
According to above-mentioned second embodiment, even when Wood products need have translucent portion, also can be with first embodiment similarly the procedure of processing by still less by the such Wood products of less components manufacturing.Thereby, the method and the compressed wood product of more economical converted timber can be provided.
And according to second embodiment, because the protuberance of metal die has mild curved ramp, therefore, the thin portion of compressed wood product can have gradation, and this helps to improve the design of compressed wood product.Thereby, also be applicable to the processing of the compressed wood product except electronic equipment casing according to the converted timber method of second embodiment.For example, the method for second embodiment is applicable to the processing of housing (such as the housing that is used for glasses and powder agglomates) and annex.
Beyond any doubt, the shape and the quantity that are formed on the protuberance on the metal die determines according to various situations, for example the kind of the shape of Wan Gong compressed wood product or purposes and the timber that adopted.
Figure 12 represents the structure of conduct according to the vase of the compressed wood product of the 3rd embodiment.The vase 21 of Figure 12 is formed by compression wood, and has the translucent thin portion 211 that forms along the vertical direction of Figure 12.Thin portion 211 is that at least 0.75 and more preferably at least 0.80 compression wood forms by the compression ratio on thickness direction.
In the 3rd embodiment,, therefore can visually determine the water yield the vase 21 from the outside because vase 21 has aforesaid thin portion 211.And, in the 3rd embodiment,, therefore there is not independent transparent component to be attached to abutment on the other parts because the other parts of thin portion 211 and vase 21 form, can improve the sealing property of vase thus, thereby can prevent that the seepage in the vase 21 from arriving outside.
In Figure 12, the side view of thin portion 211 and vase 21 itself forms the del that width reduces gradually downwards similarly.This shape of thin portion 211 only is an example.Should thin portion can have Any shape, as long as this thin portion allows the water yield in visually definite vase.
Figure 13 represents the structure of conduct according to the watering pot of the compressed wood product of the modification of the 3rd embodiment.Watering pot 22 shown in Figure 13 has main body 221, handle 222, handgrip 223 and the jet pipe 224 that is formed by compression wood.Main body 221 has and forms the roughly translucent thin portion 225 of blade shaped.Be similar to the thin portion 211 of vase 21, thin portion 225 allows by it from visually determining the water yield in the main body 221.Handle 222, handgrip 223 and jet pipe 224 can be formed by the material outside the timber (for example metal or synthetic resin).
Compressed wood product according to another modification of the 3rd embodiment can be the covering (not shown) that is used for the kettle main body.Such covering be located on the kettle the corresponding position of water meter that is contained in the water yield in the kettle with indication and can have thin portion, make and when this covering is attached on the kettle, can see water meter from the outside.In this case, the entire body of kettle can form with transparent material, and perhaps only water meter can form with transparent material.In either case, can visually determine the water yield in the kettle from the outside by means of thin portion.
Similar with the compressed wood product of first and second embodiments, can utilize metal die by compressing the compressed wood product of formation according to the 3rd embodiment, these die formings are corresponding with the completion shape of compressed wood product under the high-temperature high-pressure steam environment.The 4th embodiment to the eight embodiments as described below are like this equally.
Figure 14 represents the structure of conduct according to the castor of the compressed wood product of the 4th embodiment.Castor 23 shown in Figure 14 is used to store the powder condiment such as salt and pepper powder, and comprises the main body 231 that the box-like compression wood spare that opened wide by an end forms and have a plurality of holes and be attached to cap 232 on the open end of main body 231.Cap 232 is formed by metal or synthetic resin.
On the side surface of main body 231, be formed with translucent thin portion 233 along the vertical direction of Figure 14.Should thin portion 233 be that at least 0.75 and more preferably at least 0.80 compression wood spare forms by the compression ratio on thickness direction.The surplus of the condiment in the main body 231 can visually be determined from the outside by means of thin portion 233.
