The mainboard 11a of lid 11 has the opening 13 and 14 that exposes image-generating unit 5 and flash lamp 6 respectively, and image-generating unit 5 has sampling image lens.The side plate 11b and the 11c of lid 11 have notch 151 and 161 respectively.
On the other hand, the mainboard 12a of lid 12 comprises the opening 17 that exposes display unit 8, and display unit 8 is used for displays image information or text message by enforcements such as LCD, plasma display, organic electroluminescent (EL) displays.On opening 17, the guard member made by glass etc. is installed with protection display unit 8.The side plate 12b and the 12c of lid 12 comprise notch 152 and 162 respectively.
When the lid 11 and 12 that will have said structure in the assembling of digital camera 100 was bonded together, notch 151 and 152 faced with each other with formation opening 15, and notch 161 and 162 faces with each other to form opening 16.Opening 15 exposes shutter release button 7, and opening 16 exposes the jockey that is used to be connected to such as the external device (ED) of personal computer.This jockey for example is such as the splicing ear of USB (USB) terminal, is used for such as the connectivity port of the exterior storage medium of xD picture card, smart media card etc. and the socket that is used for power supply.Can be opening 16 cap (cap) is set, be used for protecting the jockey that does not use.
In addition, lid 11 and 12 can comprise that additional opening and additional incisions portion are to install view finder or to expose the manual operation button.
As shown in Figure 3, shell 1 holds the electronic component that at least a portion realizes the electric function of digital camera 100, more particularly, described electronic component comprises: control module 9, and it comprises the control circuit of the driving that control and the imaging of digital camera 100 etc. are relevant; Image-forming component, for example charge coupled device (CCD); And electronic unit, it comprises the sound input-output element such as microphone, loudspeaker etc.By having the operation and the CPU (CPU) of control function, storing such as the flash memory of the various information of the program that is used to move scheduled operation system (OS) and realize control circuit.
When thereby lid 11 and 12 assemblings form shells 1 and hold electronic component, apply adhesive etc. to the end face of the correspondence of the side plate of lid 11 and 12.After engaging two lids,, available sealant such as elastomeric material makes its sealing thereby covering the periphery of the interface of two lids.Perhaps can on an end of one the side plate of two lids in 11 and 12, form a groove, and can on an end of the side plate of another lid, form the projection that will cooperate, and this projection can be assembled in the described groove at joint with described groove.
To describe the method that lid is processed into said structure in detail below.At first, cut out as the wood piece that is used to cover 11 or 12 material from log.Fig. 4 is a key diagram, schematically shows from unpressed log 50 wood piece of one- tenth lid 11 and 12 to be processed is shaped.Be smooth and cut out as the wood piece 51 of the material that is used for exterior part 111 or 121 from log 50, thus wood piece 51 vertically and the direction L of the wood-fibred of log 50 substantially parallel.As shown in Figure 5, the wood piece 51 of Cheng Xinging has the straight burr surface and has thickness R like this, and wherein texture 50G extends with being substantially parallel to each other.
On the other hand, be smooth and cut out from log 50 as the wood piece 52 of the material that is used for inner part 112 or 122, thus wood piece 52 laterally and the direction L of the wood-fibred of log 50 substantially parallel.Fig. 6 is the stereogram of the structure of the wood piece 52 that cuts out.Similar with wood piece 51, wood piece 52 have thickness R and straight burr surface, but length in the vertical is shorter than wood piece 51.
Here, wood piece 51 and 52 cuts out from log 50, thereby the volume of the volume ratio finished piece(s) of the wood piece that cuts out 51 and 52 goes out the amount that reduces greatly in the compression process of describing after a while.Adoptable log for example is Japanese cypress, Bai Xuesong (hiba cedar), paulownia, Japanese cedar, pine, cherry, beech tree, ebony, teak, mahogany and rosewood among first embodiment.Any of these timber kinds can be used as the log among all embodiment of the present invention.
After cutting out, wood piece 51 is compressed (first compression process).Fig. 7 is a key diagram, and how first compression process of schematically illustrated wood piece 51 is carried out, and Fig. 8 is wood piece 51 and the metal pattern cutaway view along line B-B shown in Figure 7.As shown in Figure 7 and Figure 8, wood piece 51 is compressed by two metal patterns 61 and 71 in first compression process.In these two metal patterns, be used for having downward projection 62 from the metal pattern 61 that the last direction wood piece 51 of wood piece 51 is exerted pressure.On the other hand, the metal pattern 71 that is used for exerting pressure from the following direction wood piece 51 of wood piece 51 during compression process has downward recess 72.
Before first compression process, wood piece 51 is retained in preset time section in the water vapor atmosphere of HTHP.Thereby wood piece 51 absorbs excessive water and is softened.Make at least one another in the close metal pattern 61 and 71 in identical water vapor atmosphere in the metal pattern 61 and 71 afterwards, thus clamping and compression wood spare 51.Fig. 9 is by the vertical sectional view of the wood piece 51 of metal pattern 61 and 71 clampings and compression along the line B-B of Fig. 7, and is similar with Fig. 8.As shown in Figure 9, wood piece 51 is deformed into the 3D shape of the basic peviform corresponding with the gap that forms between projection 62 and recess 72 in by two metal patterns 61 and 71 clampings and compression.
According to first embodiment, wood piece 51 has homogeneous thickness r on its whole zone by the distortion of first compression process
1(＜R).The compression ratio C of wood piece 51 in first compression process
1Can be expressed as (R-r
1)/R.Specifically, compression ratio C
1Be similar in 0.3 to 0.6 scope.
When wood piece 51 is retained under as shown in Figure 9 the state after the preset time section, metal pattern 61 separates with metal pattern 71 with release wood piece 51 from compression and water vapor atmosphere, makes wood piece 51 dryings then.According to the material of wood piece 51, wood piece 51 may revert to original shape when metal pattern 61 and 71 discharges.When adopting such timber, wood piece 51 retaining clip between compression release and dry period is held between metal pattern 61 and 71.The time span of desiccated wood spare 51 can change according to the shape and the kind of wood piece 51.
First compression process that is used for wood piece 51 has been described like this.Wood piece 52 is carried out the first similar compression process.In first compression process of wood piece 52, adopt metal pattern 61 and 71 different metal patterns with the compression that is used for wood piece 51, thereby wood piece 52 becomes after first compression process than wood piece 51 smaller peviform shape after first compression process, and has homogeneous thickness r substantially on its whole zone
2(＜R).The compression ratio C of wood piece 52 in first compression process
2Can be expressed as (R-r
2)/R.
In first embodiment, metal pattern is designed so that the thickness r of wood piece 51 after first compression process
1Thickness r with wood piece 52
2Equate.Therefore, the compression ratio C of wood piece 51 in first compression process
1Compression ratio C with wood piece 52
2Identical (that is C,
1=C
2).Hereinafter, the wood piece 51 and 52 after first compression process is called exterior part 111 and inner part 112.
After above-mentioned first compression process, exterior part 111 and inner part 112 are stacked and be compressed in (second compression process) together.Hereinafter, will describe by example and cover 11 shaping.Lid 12 forms in the same manner.
Figure 10 is a key diagram, and how schematically illustrated second compression process is carried out, and Figure 11 is inner part, exterior part and the metal pattern cutaway view along line C-C shown in Figure 10.In second compression process, with first compression process in the identical high-temperature high-pressure steam environment, inner part 112 is placed on the exterior part 111, and with two parts 111 and 112 precalculated positions that are placed between metal pattern 81 and 91.Then, two metal pattern clampings are also compressed exterior part 111 and inner part 112, so that these two part distortion become reservation shape.
The metal pattern 81 of exerting pressure to inner part 112 from the top has the projection 82 that cooperates with the inner surface of inner part 112.Projection 82 has the curved surface that cooperates with the inner surface of the bend 112ab that extends between the bottom of inner part 112 and sidepiece.The radius of curvature R A of the curved surface of projection 82 is less than the radius of curvature R I of the inner surface of bend 112ab.The metal pattern 91 of exerting pressure to exterior part 111 from the below on the other hand, has the recess 92 that cooperates with the outer surface of exterior part 111.Recess 92 have with the bottom of parts 111 outside and sidepiece between the curved surface that cooperates of the outer surface of the bend 111ab that extends.The radius of curvature R B of the curved surface of recess 92 is less than the radius of curvature R O of the outer surface of bend 111ab.
Figure 12 is by the exterior part 111 of metal pattern 81 and 91 clampings and compression and inner part 112 vertical sectional view along the line C-C of Figure 10, and is similar with Figure 11.Exterior part 111 and inner part 112 further are compressed under the state shown in Figure 12.In second compression process, the resin composition oozes out and as adhesive from exterior part 111 and inner part 112, so exterior part 111 and inner part 112 are bonded to each other and need not apply adhesive.Here, according to the material of exterior part 111 and inner part 112, before second compression process, can apply the adhesive of appropriate amount to the contact surface of exterior part 111 and inner part 112.
Afterwards, along with in the precalculated position, forming opening, notch etc. by cutting or punching, lid 11 completions.If the lid 11 of completion has unnecessary portions on its periphery, then remove this part and on the surface that generates, carry out suitable processing by cutting.
Figure 15 is a vertical sectional view, schematically shows as mentioned above the example that becomes to cover the intensity distributions of 11 exterior part 111 and inner part 112 by compression process.Exterior part 111 and inner part 112 are directly bearing in the region S from the near surface of the pressure of metal pattern after first compression process, have to compare relative higher intensity with zone line M.
When covering 11 by second compression process formation of stacked exterior part 111 and inner part 112, lid 11 region S at its near surface
1Pressure bears with the increase fibre density in the place, thereby has further increased its intensity.In addition, the region S of the near surface that is attached to each other of exterior part 111 and inner part 112
2Though intensity be lower than region S
1, but than zone line M
1Height, and region S
2Thicker relatively.Thereby in lid 11, the higher relatively layer of intensity alternately is superimposed upon on the relatively low layer of intensity in every way, thereby can obtain the yielding material of high strength and high tenacity by twice compression process.
According to above-mentioned first embodiment, compress two wooden sheets (first compression process) at first separately, then with the wooden sheet of two compressions of piling up (second compression process) further compressed together.Thereby wood piece can be in first compression process attenuation to help its shaping.
In addition, according to first embodiment, twice compression process generated such wood piece product, and higher layer and the lower layer of intensity of intensity alternately piles up in this wood piece product, the intensity difference of each layer, thus the yielding compressed wood product of high strength and high tenacity can be provided.
Say that further according to first embodiment, the direction of wooden fibers in the exterior part of lid is vertical substantially with the direction of wooden fibers in the inner part of lid.Thereby direction is surfacewise replenished the undercapacity in another parts thereby each of exterior part and inner part can work.Therefore, the intensity of direction surfacewise that can eliminate wood piece is inhomogeneous, thereby gives wood piece even and suitable intensity.
Optionally, opposite with first embodiment, can make the direction of wood-fibred of exterior part 111 laterally substantially parallel with it, and can make the direction of wood-fibred of inner part 112 vertically substantially parallel, thereby make the direction of wood-fibred of exterior part 111 vertical substantially with the direction of the wood-fibred of inner part 112 with it.
Still optionally, the direction of wooden fibers of two wood pieces needn't be vertical substantially.In other words, intersected with each other as long as the direction of wooden fibers of two wood pieces is arranged to, just can obtain the similar advantage among first embodiment.In this, the wood piece that cuts out from log 50 needn't have the straight burr surface.
Still optionally, in lid 11 and lid 12, the direction of wooden fibers of exterior part and inner part and shape thereof can be opposite.For example, lid 11 can form similarly with first embodiment, form and make the direction of wooden fibers of exterior part 121 with laterally substantially parallel and cover 12, and the direction of wooden fibers of inner part 122 is with vertically substantially parallel.
In the above description, stacked two wooden sheets form compressed wood product.Yet compressed wood product can be formed by the wooden sheet more than two.For example, when three of employings have the wooden sheet on straight burr surface, three wooden sheets can be arranged so that its direction of wooden fibers forms the angles of approximate 60 degree each other.Thereby wooden sheet can replenish the deficiency of intensity each other, thereby improves the bulk strength that generates product.Usually, when adopting the wooden sheet on n (n is not less than two natural number) straight burr surface here, be arranged to make its wood-fibred to form the angle of 180/n degree each other wooden sheet.
Below show as the example that is used for such as the appropriate size of the lid shell of the small portable electronic device of digital camera, that make by two wooden sheets.At first, cut out two smooth wooden sheets, make every thickness R be approximately 2 millimeters (mm), and these two wooden sheets of compression have approximate 1.0 to 1.1mm thickness up to each wooden sheet in first compression process.In second compression process subsequently, the wooden sheet of compression engagement is approximately 1.6 to 1.8mm up to its gross thickness 2r.
Second embodiment

222Respectively with the lid 21 and 22 vertically substantially parallel.When exterior part has the plain weave surface, the wood-fibred pattern that promptly has inhomogeneous extension, and inner part has the straight burr surface, the wood-fibred pattern that promptly has even extension, and described exterior part and described inner part is stacked and form and cover 21 and at 22 o'clock, and the direction of wooden fibers in exterior part and the inner part is intersected with each other.Therefore, the anisotropy of the intensity of each lid reduces.
The mainboard 21a of lid 21 comprises opening 23 that exposes image-generating unit 5 and the opening 24 that is used to install flash lamp 6.The side plate 21b and the 21c of lid 21 have notch 251 and 261 respectively.
On the other hand; the mainboard 22a of lid 22 comprises the opening 27 that exposes display unit 8; and the guard member made by glass etc. is set with protection display unit 8 on opening 27, this display unit 8 is by enforcements such as LCD, plasma display, OLED displays.The side plate 22b and the 22c of lid 22 comprise notch 252 and 262 respectively.
When the lid 21 and 22 that will have said structure in the assembling of digital camera 200 was bonded together, notch 251 and 252 faced with each other with formation opening 25, and notch 261 and 262 faces with each other to form opening 26.Opening 25 exposes shutter release button 7, and opening 26 exposes the jockey that is used to be connected to such as the external device (ED) of personal computer.Can be opening 26 is provided with a cap and is used for protecting not the jockey that uses.
To describe the method that lid is processed into said structure in detail below.At first, cut out as the wood piece that is used to cover 21 or 22 material, make the wood piece that cuts out go out the amount that reduces by compression than finished piece(s) is big from log.Figure 18 is a key diagram, schematically shows to make as the wood piece that is used to cover 21 and 22 material from unpressed log 50 to be shaped.Be smooth and cut out as the wood piece 53 of the material that is used for exterior part 211 or 221 from log 50, thus wood piece 53 vertically and the direction L of the wood-fibred of log 50 substantially parallel.The wood piece 53 of Huo Deing has plain weave surface (seeing Figure 19) like this.
On the other hand, cut out from log 50 as the wood piece 54 of the material that is used for inner part 212 or 222, thus wood piece 54 vertically and the direction L of the wood-fibred of log 50 substantially parallel, and have the straight burr surface.Wood piece 54 has the structure identical with wood piece shown in Figure 5 51.Wood piece 53 is identical with 54 thickness, is expressed as R.Wood piece 53 is longer than wood piece 54 in the vertical.
Then, with the wood piece 53 and 54 compressions (first compression process) that cut out.In first compression process, wood piece 53 and 54 is retained in preset time section in the water vapor atmosphere of HTHP before compression.Afterwards, excess water and softening wood piece 53 and 54 have been absorbed with two predetermined metal pattern clampings with compression.
By first compression process, wood piece 53 and 54 is out of shape and has basic homogeneous thickness r respectively on its whole zone
3(＜R) and r
4(＜R).The compression ratio C of wood piece 53
3=(R-r
3The compression ratio C of)/R and wood piece 54
4=(R-r
4)/R is approximately 0.3 to 0.6.
Figure 20 is a key diagram, and how schematically illustrated second compression process is carried out, and wherein the exterior part 211 that forms of the independent compression by each wood piece 53 and 54 and inner part 212 are by stacked on top of each other and compressed together.Hereinafter describe and cover 21 second compression process.Also carry out the second identical compression process to covering 22.In second compression process, with first compression process in the identical high-temperature high-pressure steam environment, inner part 212 is placed on the exterior part 211, and with two parts 211 and 212 precalculated positions that are placed between metal pattern 81 and 91.Then, two metal pattern clampings are also compressed exterior part 211 and inner part 212, so that these two part distortion become reservation shape.
Afterwards, exterior part 211 and inner part 212 are discharged from compression and drying, thereby obtain to cover 21 original form.Therefore, the thickness of lid 21 becomes approximate 30% to 50% of the gross thickness 2R of two wood pieces before compression.Therefore, the compression ratio by twice compression process is approximately 0.5 to 0.7, and this is more bigger than the compression ratio in first compression process (approximate 0.3 to 0.6).
Afterwards, along with in the precalculated position of the lid 21 of compression, forming opening, notch etc. by cutting or punching, lid 21 completions.If the lid 21 of completion has unnecessary portions on its periphery, then remove this part and on the surface that generates, carry out suitable processing by cutting.
Therefore, the second embodiment of the present invention has realized the advantage identical with first embodiment.According to above-mentioned second embodiment, compress two wooden sheets (first compression process) separately, then with two compression wood sheets that pile up (second compression process) compressed together.Thereby wood piece can be in first compression process attenuation to help its shaping.
In addition, according to second embodiment, twice compression process generated such wood piece product, in this wood piece product, the layer that layer that intensity is higher and intensity are lower alternately piles up, the intensity difference (seeing Figure 15) of each layer, thus give yielding compressed wood product suitable and uniform intensity, and the compressed wood product of high strength and high tenacity can be provided.
Say that further according to second embodiment, the textured pattern that constitutes the exterior part of lid and inner part is different, thereby make the direction direction surfacewise intersected with each other of the wood-fibred in exterior part and the inner part replenish the undercapacity of weak location each other.Therefore, it is inhomogeneous to eliminate the intensity of direction surfacewise of wood piece.
Thereby in a second embodiment, employing has the wood piece on plain weave surface and has the wood piece on straight burr surface respectively as exterior part and inner part.The selection of this textured pattern is preferred in the following areas.At first, though classify as mentioned above, the plain weave pattern is at different pattern shown in each wood piece.When adopting flat-grained timber spare as the exterior part of product, textured pattern can be that a part and each product of product design can illustrate more significantly and unique personal feature.Secondly, straight grained wood spare has lower anisotropy easily and its direction of wooden fibers is identical.Therefore, described wood piece is very firm for the power that applies along the direction perpendicular to direction of wooden fibers, and is used for processing along the machine direction bending easily.Thereby the combination of flat-grained timber spare and straight grained wood spare can be made the compressed wood product of the advantage with both.
Perhaps, can adopt the wood piece with end grain surface as exterior part, perhaps can adopt the wood piece with the textured pattern except that the straight burr pattern, for example, the wood piece that can adopt the middle textured pattern with straight burr and plain weave is as inner part.Specifically, flat-grained timber spare is relative with the end grain wood piece softer and contain higher relatively resin composition.Thereby, use this wood piece to be created in second compression process easily the additional advantage that wood piece is combined with other parts in the product.
In a second embodiment, similar to first embodiment, compressed wood product can be formed by the wood piece more than two.As mentioned above, the design of flat-grained timber spare and end grain wood piece is unique.For example, when adopting flat-grained timber spare or end grain wood piece as exterior part, and adopting two straight grained wood spares all to be superimposed upon when making on the exterior part that the direction of wooden fibers of two straight grained wood spares is basic vertical each other and they being carried out second compression process as inner part and with them, the compressed wood product of generation can be enjoyed suitable intensity and good design.Here, flat-grained timber spare or end grain wood piece are can be thinner than each of other two straight grained wood spares when log takes out.

Exterior part 311,321 and inner part 312,322 all are straight grained wood spares.In these wood pieces, the direction of wooden fibers of exterior part 311 and inner part 312 is vertically substantially parallel with lid 31, and the stacked exterior part 311 and the texture 50G of inner part 312 are basic identical.In addition, the direction of wooden fibers of exterior part 321 and inner part 322 is vertically substantially parallel with lid 32, and the stacked exterior part 321 and the texture 50G of inner part 322 are basic identical.
The mainboard 31a of lid 31 comprises opening 33 that exposes image-generating unit 5 and the opening 34 that is used to install flash lamp 6.The side plate 31b and the 31c of lid 31 have notch 351 and 361 respectively.
On the other hand; the mainboard 32a of lid 32 comprises the opening 37 that exposes display unit 8; and the guard member made by glass etc. is installed with protection display unit 8 on opening 37, this display unit 8 is by enforcements such as LCD, plasma display, OLED displays.The side plate 32b and the 32c of lid 32 comprise notch 352 and 362 respectively.
When the lid 31 and 32 that will have said structure in the assembling of digital camera 300 was bonded together, notch 351 and 352 faced with each other with formation opening 35, and notch 361 and 362 faces with each other to form opening 36.Opening 35 exposes shutter release button 7, and opening 36 exposes the jockey that is used to be connected to such as the external device (ED) of personal computer.Can be opening 36 cap is set, be used for protecting the jockey that does not use.
To describe the method that lid is processed into said structure in detail below.At first, cut out as the wood piece that is used to cover 31 or 32 material, make the wood piece that cuts out go out the amount that reduces by compression than finished piece(s) is big from unpressed log 50.
Figure 23 is a key diagram, schematically shows from unpressed log 50 shaping wood pieces, and this wood piece is to be used to cover 31 and 32 material.Be smooth and cut out as the wood piece 55 of the material that is used for exterior part 311 or 321 from log 50, thus wood piece 55 vertically and the direction L of the wood-fibred of log 50 substantially parallel, thereby show the straight burr pattern.Be smooth and cut out as the wood piece 56 of the material that is used for inner part 312 or 322 from log 50, thus wood piece 56 vertically and the direction L of the wood-fibred of log 50 substantially parallel, thereby show the straight burr pattern.Wood piece 55 is identical with 56 thickness, is expressed as R.Wood piece 55 is longer than wood piece 56 in the vertical.
Then, with the wood piece 55 and 56 compressions (first compression process) that cut out.In first compression process, wood piece 55 and 56 is retained in preset time section in the water vapor atmosphere of HTHP before compression.Afterwards, excess water and softening wood piece 55 and 56 have been absorbed with two predetermined metal pattern clampings with compression.
By first compression process, wood piece 55 and 56 is out of shape and has basic homogeneous thickness r respectively on its whole zone
5(＜R) and r
6(＜R).In the 3rd embodiment, carry out first compression process and make the thickness r of wood piece 55
5Equal the thickness r of wood piece 56
6The compression ratio C of wood piece 55
5=(R-r
5The compression ratio C of)/R and wood piece 56
6=(R-r
6)/R equates and is approximately 0.3 to 0.6.
Figure 24 is a key diagram, and how schematically illustrated second compression process is carried out, and wherein the exterior part 311 that forms of the independent compression by each wood piece 55 and 56 and inner part 312 are by stacked on top of each other and compressed together.Hereinafter describe and cover 31 second compression process.Also carry out the second identical compression process to covering 32.
In second compression process, with first compression process in the identical high-temperature high-pressure steam environment, inner part 312 is placed on the exterior part 311, and with two parts 311 and 312 pre-positions that are placed between metal pattern 81 and 91.Then, two metal pattern clampings are also compressed exterior part 311 and inner part 312, so that these two part distortion become reservation shape.
Afterwards, exterior part 311 and inner part 312 are discharged from compression and drying, thereby obtain to cover 31 original form.Therefore, the thickness of lid 31 becomes approximate 30% to 50% of the gross thickness 2R of two wood pieces before compression.Therefore, the compression ratio by twice compression process is approximately 0.5 to 0.7, and this is more bigger than the compression ratio in first compression process (approximate 0.3 to 0.6).
Afterwards, along with in the precalculated position of the lid 31 of compression, forming opening, notch etc. by cutting or punching, lid 31 completions.If the lid 31 of completion has unnecessary portions on its periphery, then remove this part and on the surface that generates, carry out suitable processing by cutting.
In the 3rd embodiment, the textured pattern of exterior part and inner part is generally basic identical after second compression process.Therefore, the pucker ﹠ bloat of the shell 3 that causes owing to the change that applies external force or temperature or humidity is basic identical in exterior part that is engaged with each other and inner part.Therefore, stress can not concentrate in exterior part and the inner part.Therefore, product can have such special benefits,, even under the situation that applies the change of external force or temperature or humidity, also can not produce strain that is.
In addition, when the textured pattern of exterior part and inner part was basic identical, the product of generation can have the similar characteristic of compressed wood product with the analogous shape of being made by a wood piece.On the other hand, though direction of wooden fibers in the exterior part and the direction of wooden fibers in the inner part are substantially parallel, exterior part and the inner part textured pattern after being bonded together can not mate each other fully.Therefore, the compressed wood product of being made by a plurality of parts as among the embodiment can have less intensity anisotropy, and its intensity is compared more even with the compressed wood product of being made by a wood piece.
In the 3rd embodiment, the wood piece of employing needs not to be straight grained wood spare, as long as the textured pattern of exterior part and inner part is basic identical.Optionally, can adopt flat-grained timber spare, end grain wood piece or have plain weave and the wood piece of the middle textured pattern of straight burr.
According to above-mentioned the 3rd embodiment, similar to above-mentioned two embodiment, compress two wooden sheets (first compression process) separately, then with two compression wood sheets that pile up (second compression process) further compressed together.Thereby similar to above-mentioned two embodiment, wood piece can be in first compression process attenuation to help its shaping.
In addition, according to the 3rd embodiment, twice compression process generated such wood piece product, this wood piece product comprises higher layer and the lower layer of intensity of intensity that alternately piles up, the intensity difference (seeing Figure 15) of each layer, thus the yielding compressed wood product of high strength and high tenacity can be provided.
In addition, according to the 3rd embodiment, the exterior part and the inner part that constitute lid are stacked, make their textured pattern mate substantially and finalize the design in second compression process.Thereby, thereby two parts of typing substantially in the same manner expansion prevent concentrating of internal stress.Thereby, even under the situation that applies the change of external force or temperature or humidity, also be not easy to produce strain.
In addition, according to the 3rd embodiment, though the coupling of textured pattern is given the similar advantage that product is found in the product of being made by a wood piece, the textured pattern of stack parts can not mate fully.Therefore, compare with the compressed wood product of making by a wood piece, the anisotropy of intensity can be less and bulk strength product can be more even.
The 4th embodiment
Figure 25 is a key diagram, and being shown schematically in second compression process according to the method for the converted timber of fourth embodiment of the invention is converted timber spare how.As shown in figure 25, carrying out second compression process with identical compression ratio on through the exterior part 411 of first compression process and inner part 412, and between them, plugging reinforcement 413.First compression process is identical with first compression process of above-mentioned first to the 3rd embodiment, wherein will be collapsed into exterior part 411 and inner part 412 from the smooth wood piece that log cuts out separately.
In Figure 25, for exterior part 411 and inner part 412, the textured pattern of the wood-fibred in exterior part 411 and the inner part 412 or direction be not clearly shown that the textured pattern and the direction of wood-fibred, because no matter how, all can adopt the method according to the converted timber of the 4th embodiment.
For example, if exterior part 411 and inner part 412 are exterior part 111 and inner part 112 similar straight grained wood spares with first embodiment, then the direction of wooden fibers of exterior part 411 be arranged to cover 41 vertically substantially parallel, and the direction of wooden fibers of inner part 412 be arranged to cover 41 laterally substantially parallel.Thereby, if reinforcement 413 is arranged between exterior part 411 and the inner part 412, make machine direction wherein all form miter angle with the direction of wooden fibers of exterior part 411 and the direction of wooden fibers of inner part 412, then reinforcement 413 can be used for the product that direction a little less than the intensity relative thin is strengthened the generation that wherein exterior part 411 and inner part 412 superpose.
Figure 26 is the stereogram of the structure after second compression process of lid 41 before compression release and drying that completes, and Figure 27 covers 41 cutaway views along line E-E shown in Figure 26.As Figure 26 and shown in Figure 27, reinforcement 413 is after being compressed between exterior part 411 and the inner part 412, in the surface of partly nip exterior part 411 and inner part 412.Yet reinforcement 413 is mainly formed by composition contained in the timber, and is therefore higher with the compatibility of timber.As a result, reinforcement 413 is fixed to the surface of wood piece in compatible state under the situation by damage wood-fibreds such as cuttings not.
In addition, when applying the change of external force or temperature or humidity, reinforcement 413 is out of shape along with the distortion of lid 41, thereby prevents to cover 41 excessive deformation.This is because reinforcement 413 is mainly formed by composition contained in the timber, and the Young's modulus of reinforcement 413, thermal coefficient of expansion and hygral expansion coefficient are close with the hygral expansion coefficient with the Young's modulus, the thermal coefficient of expansion that cover 41 respectively.
Here, the direction of wooden fibers of reinforcement 413 needn't be arranged in the same manner, can be at random.Still optionally, reinforcement 413 can be formed by the braided fiber of similar net.In addition, the length of each fiber needn't be consistent, and reinforcement 413 can be formed by the thin especially fabric that silk, fiber crops, non-woven fabric etc. are made.
The material that is used for reinforcement 413 is not limited to comprise the material of wood fiber component.For example, can adopt carbon fiber, and can adopt the suitable material that is stained with predetermined fabric as reinforcement 413 as reinforcement 413.Still optionally, reinforcement 413 can be formed by sheet metal or wire netting.
The lid 41 that forms as mentioned above be similar to cover 41 form another cover the shell that (not shown) have constituted electronic equipment.Be used for electronic equipment, for example be used for digital camera shell structure and assemble method etc. respectively be used for according to identical (except there is reinforcement 413 in the former) (seeing Fig. 1 to Fig. 3) such as the structure of the shell 1 of the digital camera 100 of first embodiment and assemble methods.
According to the 4th embodiment of the invention described above, can easily form compressed wood product by twice compression process, and can on its whole zone, provide suitable intensity.
In addition, according to the 4th embodiment,, can further improve the intensity of lid by the reinforcement between exterior part and the inner part of being arranged on of lid (compressed wood product).
Specifically, comprise the reinforcement of wood fiber component by utilization, the shrinkage factor of reinforcement and the shrinkage factor of wood piece are basic identical.Thereby, but the compatibility of reinforcement and timber is higher and the quality homogenising of product material.Say that further the reinforcement that comprises wood fiber component is not cut the wood-fibred of wood piece itself, thereby further improved the intensity of lid because compressed wood product does not reduce the intensity of wood piece itself.
Here, reinforcement can be applicable to one or two in the inner surface of the outer surface of exterior part and inner part.When reinforcement was arranged on the outer surface of exterior part, reinforcement was as the part of the product design unique quality with further enhancing product, and helped to improve the intensity of compressed wood product.On the other hand, when reinforcement is arranged on the inner surface of inner part, can improves the intensity of compressed wood product and do not influence its outward appearance.
When employing was made compressed wood product more than two wood piece, reinforcement can be arranged between at least one pair of adjacent wood piece.
Other embodiment
Though abovely as first to fourth embodiment, describe exemplary embodiment of the present invention in detail, the invention is not restricted to the foregoing description.Below other embodiments of the invention will be described.
(1) the electric function element can be arranged between the exterior part and inner part of lid.For example, parts and inner part are provided with the earthed circuit plate outside, make earthed circuit can be connected to the electronic component that is contained in the shell.Thereby the space that is used for earthed circuit that can be provided with usually in the enclosure is optional, thereby can save the space.In addition, between parts and the inner part sheet metal is set outside.Sheet metal also is used as the shielding material that the protection product is not influenced by electromagnetic wave except as the reinforcement.Still optionally, be arranged on the sheet that wherein is equipped with IC chip or various installation elements, flexible base, board etc. outside between parts and the inner part.Thereby can in the electronic equipment of making, realize various functions.
When lid when forming more than two wood pieces, reinforcement and electric function element can be arranged on all places place.Described element can make up setting according to the purposes of lid.
(2) Figure 28 is the cutaway view of the structure of the lid made by the compressed wood product of exterior part that wherein has different-thickness and inner part.Identical in the compression ratio of exterior part 451 and inner part 452 and first and second compression process.As shown in figure 28, to have thickness be h to lid 45
1Exterior part 451, thickness h
1Thickness h than inner part 452
2Little (h
1＜h
2).Because exterior part 451 is thinner relatively, thus can adopt easy crack and the wood piece that is difficult to be shaped as material.For example, can adopt flat-grained timber spare or end grain wood piece as exterior part 451.Thereby,, simplified first compression process and can prevent the damage in generation such as crack in wood piece by using thin wood piece.
On the other hand, by using such as the higher wood piece of the intensity of straight grained wood spare as inner part, though the not change of the whole thickness of lid itself can improve by the thickness recruitment of the higher parts of intensity and cover 45 bulk strength.When the processing of tabular wood piece being carried out such as bending, and in first compression process exterior part and inner part deformation extent not simultaneously, it is thin that the higher parts of deformation extent can be arranged to the yielding parts of specific volume.
(3) thickness by being adjusted at the wood piece that adopts in first compression process and the shape of metal pattern can change the compression ratio of exterior part and inner part for each parts.The tone of wood piece after compression that takes out from the timber of identical type changes according to compression ratio.More particularly, compression ratio is high more, just promotes the carbonization of wood piece more, thereby makes the surface color deepening.In addition, the wood piece that compresses with higher relatively compression ratio shows improved surface flatness and gloss, and anti-soil more.
On the contrary, compare, though that the wood piece that compresses with relatively low compression ratio shows the change of surface color is less, softer with the wood piece that compresses with relative higher compression ratio.In addition, the wood piece that compresses with relatively low compression ratio keeps more timber shape texture, and sensation better.If consider above-mentioned feature,, then can make the compressed wood product of uniqueness with various tones according to the design of product to be made or the compression ratio of property settings wood piece.
For example, because the end grain wood piece is difficult to by shapings such as bendings, so that the compression ratio of end grain wood piece can be made as is lower, and because straight grained wood spare is shaped easily, so that the compression ratio of straight grained wood spare can be made as is higher.Thereby compressed wood product can easily be piled up by these and wood piece compressed together forms.Thereby the product that the wood piece that compresses with different compression ratios by combination generates in the product that generates, can be guaranteed suitable intensity, and the product shade and the product appearance of wide range are provided.
When in the scope under the limit compression ratio at wood piece this wood piece compression ratio being made as when enough high, compression not only causes tone reversal, and making the wood piece carbonization by the burning that causes of metal pattern by heating, this makes wooden material become conductor as electromagnetic shield.Therefore, when by making compressed wood product according to the method for converted timber of the present invention and when being used for the shell of electronic equipment, preferably make a wood piece become conductor by high compression rate, make another wood piece remain the insulator that carbonization does not take place, and can the wood piece with different qualities is stacked and form shell.In order to make this compressed wood product, in first compression process, can make at least one carbonization in the surface of the surface of the exterior part that faces with each other in the finished product and inner part.
Here, because make a wood piece carbonization, so can not only realize the joint of wood piece by the resin composition.Therefore must use adhesive to engage wood piece.
(4) in the above description, suppose that all wood pieces all are to take out from the timber of identical type.Yet the timber kind that is used for different parts can be different.For example, when the lid that is used for electronic equipment forms by stacked two wood pieces, can adopt the good especially timber kind of appearance as exterior part improving design performance, and adopt firm timber kind as the inner part that focuses on higher-strength.When utilizing preferably and process the combination of the wood piece that takes out from different types of timber, the compressed wood product of generation can have the intensity and the outward appearance that can not obtain when only adopting the wood piece that takes out from the timber of a kind.
Here, as mentioned above, the thickness of each parts and compression ratio can be adjusted similarly according to the processing difficulties degree of the timber that is used as exterior part and inner part.
(5) by adjusting the shape of metal pattern, work in-process has made full use of the advantage of first compression process and second compression process.More particularly, thus because each wood piece is thin to be shaped when first compression process easily, so wood piece is processed to the shape near completion in first compression process.On the other hand, the deformation extent in second compression process is made as less than the deformation extent in first compression process.In second compression process, wood piece can be along thickness direction by compress slightly.Yet second compression mainly is exclusively used in the wood piece that processing needs high alignment precision.For example, in second compression process, carry out joint, producer's name or the name of product of wood piece engraving, be used for the engraving of purpose of design etc.Thereby when making full use of two independent compression process, can form wood piece accurately.
(6) thus wood piece can cut out from log and becomes predetermined 3D shape.Opening or notch can when cutting out wood piece, log formed.Perhaps can after cutting out wood piece, log form opening or notch by cutting or punching.
(7) compressed wood product that forms by the method according to the converted timber of the embodiment of the invention is except being used for digital camera, can also be used as the sheathing material of various electronic equipments (for example such as the SoundRec medium of mobile terminals, personal handy phone system (PHS) or PDA(Personal Digital Assistant), installation such as MD, CD or the cassette tape of portable phone portable audio device, the remote controller of IC logging machine, portable television, portable radio, various household electrical appliance and DTV) with output sound.In addition, except the shell that is used for electronic equipment, also can be used for other purposes according to the compressed wood product of present embodiment.
Can and classify the embodiment that (1) to the appropriate combination of other embodiment of (7) realizes by above-mentioned first to fourth embodiment as falls within the scope of the invention.Therefore, can under the situation of the spirit or scope that do not break away from the overall invention theory that claims and equivalent thereof limit, carry out various modifications.
