Lid 12 is the shape roughly the same with lid 11, and comprises: the surface is the mainboard 12a of essentially rectangular; Two side plate 12b, their relative corresponding extensions of longer side along the direction that is approximately perpendicular to mainboard 12a from this mainboard 12a; With two side plate 12c, their corresponding extensions of relative shorter side along the direction that is approximately perpendicular to mainboard 12a from this mainboard 12a.
Fig. 3 is the cutaway view along the line A-A shown in Fig. 1.As shown in Figures 2 and 3, each lid 11 and 12 all is bonded by two wooden of compressing respectively that stack.More particularly, lid 11 is formed by two-layer, i.e. exterior part 111 and inner part 112, and lid 12 is formed by two-layer, i.e. exterior part 121 and inner part 122.
In the parts 111, wood-fibred is along being roughly parallel to lid 11 direction L longitudinally outside
111Extend, and in inner part 112, wood-fibred is along being roughly parallel to the horizontal direction L of lid 11
112Extend.In the parts 121, wood-fibred is along being roughly parallel to lid 12 direction L longitudinally outside
121Extend, and in inner part 122, wood-fibred is along being roughly parallel to the horizontal direction L of lid 12
122Extend.Therefore, in each lid, the direction of wooden fibers in the exterior part is approximately perpendicular to the direction of wooden fibers in the inner part.
The mainboard 11a of lid 11 has opening 13 and 14, and these openings expose image-generating unit 5 and the photoflash 6 with sampling image lens respectively.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 display unit 8 is exposed, and this display unit is used for displays image information or Word message by realizations such as LCD, plasma display, organic electroluminescent (EL) displays.The guard member of being made by glass etc. is installed on opening 17, is used to protect 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 is bonded together, thereby notch 151 and 152 is faced formation opening 15 mutually, thereby and notch 161 and 162 mutual facing form opening 16.Opening 15 exposes shutter release button 7, and opening 16 exposes the connection device that is used to be connected to such as the external equipment of personal computer.Described connection device 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 image card, intelligent medium etc. and the socket that is used for power supply.Can be used to protect untapped connection device for opening 16 is provided with cover cap.
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 accommodates at least a portion electronic component of the electric function of realizing digital camera 100, and more specifically says so: control module 9, and it comprises the control circuit that is used to control the driving relevant with the imaging of digital camera 100 etc.; Image-forming component such as charge-coupled device (CCD); With the electronic unit that comprises such as the audio frequency input-output element of microphone, loudspeaker etc.Utilize flash memory and have operation and the CPU (CPU) of control function realizes described control circuit, described flash memory is used for storing the various information such as the program that is used to move scheduled operation system (OS).
Thereby when assembling lid 11 and 12 when forming shell 1 and hold electronic component, applying adhesive etc. on the corresponding end-faces of the side plate of lid 11 and 12.Make after two lids engage, can use composition surface (interface) that sealant (for example, elastomeric material) covered and sealed two lids on every side.Perhaps, form groove on the end of one side plate that can be in two lids, and can form the projection that is fit to this groove on an end of the side plate of another lid, this projection can be assemblied in the described groove when engaging.
Then, the method that lid is processed into said structure will be described in detail.At first, cut out ligneous piece from log as the material of lid 11 or 12.Fig. 4 schematically represents to wait to be processed into the key diagram of the ligneous piece of lid 11 and 12 from unpressed log 50 shapings.Ligneous piece 51 as the material that is used for exterior part 111 or 121 is the plane sheets that cut out from log 50, makes the direction of wooden fibers L that vertically is roughly parallel to log 50 of ligneous piece 51.As shown in Figure 5, so the ligneous piece 51 that is shaped has the straight grain surface that texture 50G roughly is parallel to each other and extends, and has thickness R.
On the other hand, be the plane sheets that cuts out from log 50 as the ligneous piece 52 of the material that is used for inner part 112 or 122, make the direction of wooden fibers L that laterally is roughly parallel to log 50 of ligneous piece 52.Fig. 6 is the stereogram of the structure of the ligneous piece 52 that cuts out.Similar with ligneous piece 51, ligneous piece 52 has thickness R and straight grain surface, but length longitudinally is than the weak point of ligneous piece 51.
Here, cut out ligneous piece 51 and 52, make the volume ratio finished parts of the ligneous piece 51 cut out and 52 go out to treat the amount that the compression of describing in the back reduces in handling greatly from log 50.The log that can adopt in first embodiment for example is: Japanese cypress, Japanese cedar (hiba cedar), paulownia, cryptomeria, pine, cherry tree, beech tree, ebony, teak, mahogany and redwood.In all embodiment of the present invention, can adopt in these timber kinds any as log.
After cutting, ligneous piece 51 is compressed (compression is handled).Fig. 7 schematically represents how to carry out the key diagram that the compression of ligneous piece 51 is handled, and Fig. 8 is ligneous piece 51 and the metal die profile along the line B-B shown in Fig. 7.As shown in Figure 7 and Figure 8, ligneous piece 51 is compressed by two metal dies 61 and 71 in compression is handled.Among these two metal dies, be used for the metal die 61 that ligneous piece 51 applies compression stress being had downward projection 62 from the top of ligneous piece 51.On the other hand, be used for the metal die 71 that ligneous piece 51 applies compression stress being had downward depression 72 below the ligneous piece 51 in compression process.
Before compression is handled, the scheduled time is placed by ligneous piece 51 under the water vapor of HTHP.Therefore, ligneous piece 51 excessively absorbs water and softens.Afterwards, under identical water vapor atmosphere, make in metal die 61 and 71 at least one near in metal die 61 and 71 another, with clamping and compressed wooden piece 51.Fig. 9 is similar to Fig. 8, by the vertical cross section of the ligneous piece 51 of metal die 61 and 71 clampings and compression along the line B-B of Fig. 7.As shown in Figure 9, ligneous piece 51 is deformed into and the be roughly bowl-shape 3D shape corresponding in projection 62 and the gap of formation between 72 of caving in by two metal dies 61 and 71 clampings and compression.
According to first embodiment, ligneous piece 51 handles to be deformed into by compression has consistent thickness r on its whole zone
1(＜R).The compression ratio C of ligneous piece 51 in compression is handled
1Can be expressed as (R-r
1)/R.Specifically, compression ratio C
1Be similar in 0.5 to 0.7 scope.
Be in as shown in Figure 9 state after the scheduled time in ligneous piece 51, metal die 61 and metal die 71 are separated, with from compression and water vapor release ligneous piece 51, the dry wood part 51 then.From metal die 61 and 71 releases the time, original shape may recover in ligneous piece 51, and this depends on the material of ligneous piece 51.When adopting this timber, in compression release and dry run, make ligneous piece 51 keep being clamped between metal die 61 and 71.The time length that is used for dry wood part 51 can change according to the shape and the kind of ligneous piece 51.
When ligneous piece 51 and 52 has unnecessary portions because compression is handled on its periphery, remove such part and on the surface that generates, carry out the appropriate location reason by cutting.
Like this, having described the compression that is used for ligneous piece 51 handles.In ligneous piece 52, similarly compress processing.In the compression of ligneous piece 52 is handled, adopt metal die 61 and the 71 different metal dies used with being used for compressed wooden piece 51, so that the ligneous piece 52 after the compression processing is the bowl shape that is slightly smaller than the ligneous piece 51 after compression is handled, and on its roughly whole zone, has thickness r
2(＜R).The compression ratio C of ligneous piece 52 in compression is handled
2Can be expressed as (R-r
2)/R.
In first embodiment, metal die is designed to make the thickness r of ligneous piece 51
1Thickness r with ligneous piece 52
2Handling the back in compression equates.Therefore, in compression is handled, the compression ratio C of ligneous piece 51
1Compression ratio C with ligneous piece 52
2Identical (that is C,
1=C
2).Below, the ligneous piece 51 and 52 after the compression processing is called exterior part 111 and inner part 112.
As shown in figure 10, after above-mentioned compression is handled, will stack by dividing other compression to handle the exterior part 111 and the inner part 112 that form.Then, apply an amount of adhesive outside on the contact-making surface of parts 111 and inner part 112, thereby with exterior part 111 and inner part 112 bonding (adhesion process).Figure 11 is that Figure 12 is along the profile of the line C-C among Figure 11 (not shown adhesive) by the stereogram of the initial configuration of the lid 11 of adhesion process formation.
Because the inner surface of exterior part 111 is identical with the shape of the outer surface of inner part 112, therefore when bonding inner part and exterior part, do not need special alignment.But,, preferably use certain to be used for bonding anchor clamps in order to keep the loading pressure of suitable size.The combination of the metal die (corresponding to the metal die shown in Fig. 7 61) that is adopted is handled in the metal die 71 that the compression processing that an example of this anchor clamps is exterior parts 111 is adopted and the compression of inner part 112.When adopting the combination of described metal die, exterior part 111 and inner part 112 are stacked and be clamped between above-mentioned two metal dies, apply proper compression power simultaneously.
After above-mentioned finishing dealing with, form the opening or the notch of lid 11 by cutting or punching press.Figure 11 is that Figure 12 is the profile (adhesive is not shown) along the line C-C of Figure 11 by the stereogram of the initial configuration of the lid 11 of adhesion process formation.
Figure 13 is a vertical cross section, schematically represents to be processed into by compression processing and adhesion process the exterior part 111 and the intensity distributions of inner part 112 under each state of lid 11.Region S is positioned at the near surface of direct reception from the compression stress of metal die, and exterior part 111 and inner part 112 are after compression is handled, because the fibre density in the region S increases, thereby compares with zone line M to have relative higher intensity in this region S.
When the adhesion process by the exterior part 111 that stacks and inner part 112 forms lid 11, be positioned near the region S the central authorities of lid 11 ' roughly the same with the strength level of the region S of the near surface of lid 11.Near because region S described central authorities ' be to form by region S at the near surface of bonding mutually exterior part 111 and inner part 112, so its thickness is roughly the twice of region S.Therefore, in lid 11, the higher relatively layer of stacked intensity on the relatively low layer of intensity alternately in every way, thus can handle and the output material of adhesion process acquisition high strength and high tenacity by compression.
According to aforesaid first embodiment, compress two wooden (compression is handled) at first respectively, bonding then two wooden stacked (adhesion process).Therefore, in handling, compression can make ligneous piece's attenuation so that its shaping.
In addition, according to first embodiment, compression is handled to cause and is generated such ligneous piece, lower layer alternately stacked of the higher layer of intensity and intensity wherein, thus the compressed wood article of the output with high strength and high tenacity can be provided.
And according to first embodiment, the direction of wooden fibers in the exterior part of lid is approximately perpendicular to the direction of wooden fibers in the inner part of lid.Therefore each in exterior part and the inner part can both be used for replenishing the not enough intensity of another parts along surface direction.Therefore, can eliminate along the intensity of the surface direction of ligneous piece inconsistent, thereby can make ligneous piece have consistent and suitable intensity.
Alternatively, opposite with first embodiment, can make the direction of wooden fibers of exterior part 111 and the horizontal almost parallel of this exterior part, and can make the direction of wooden fibers of inner part 112 and vertical almost parallel of this inner part, thereby make the direction of wooden fibers of exterior part 111 be approximately perpendicular to the direction of wooden fibers of inner part 112.
Also alternatively, the direction of wooden fibers of two ligneous pieces must be not vertical substantially.In other words, intersected with each other as long as the direction of wooden fibers of two ligneous pieces is arranged to, just can obtain and the first embodiment confers similar advantages.Thus, must not have the straight grain surface from the ligneous piece that log 50 cuts out.
Also alternatively, the direction of wooden fibers of exterior part and inner part and their shape are at lid 11 and can be for opposite in lid 12.For example, lid 11 can be similarly constructed with first embodiment, be roughly parallel to laterally and lid 12 is formed the direction of wooden fibers that makes exterior part 121, and the direction of wooden fibers of inner part 122 is roughly parallel to vertically.
In the superincumbent description, two wooden stacks to form compressed wood article.But this compressed wood article can be by forming more than two wooden.For example, when employing had three wooden of straight grain surface, this three wooden can be arranged to make the angles of its direction of wooden fibers each other in approximate 60 degree.So these wooden can be replenished not enough intensity mutually, thereby improve the bulk strength of the product that generates.Usually, when adopting n to have wooden (, n is not less than 2 integer) on straight grain surface here, be arranged to make the angle of their wood-fibred each other in the 180/n degree with wooden.
The example of the suitable dimension that is used for lid 11 and 12 will be shown below.At first, cut out wooden 51 and 52 of two planes, make each thickness R of wooden be approximately 2 millimeters (mm) from log 50.Wooden 51 and 52 that cuts out is compressed to each wooden respectively and all has about thickness of 0.8 to 0.9mm in compression is handled.Therefore, each finished product lid 11 and 12 thickness are approximately 1.6 to 1.8mm.
Second embodiment
Figure 14 is the stereogram of the structure of an electronic equipment, and the shell of this electronic equipment is made by the compressed wood article that forms by the Wood treatment method according to second embodiment of the invention.Electronic equipment shown in Figure 14 is a digital camera 200, and this digital camera is by forming all that bowl-shape wooden lid 21 and 22 is bonded together and various electronic components are equipped with in roughly longitudinal casing 2 inside that form.
Figure 15 is the stereogram of the structure of lid 21 and 22.Lid 21 comprises: the surface is the mainboard 21a of essentially rectangular; Two side plate 21b, their relative corresponding extensions of longer side along the direction that is approximately perpendicular to mainboard 21a from this mainboard 21a; With two side plate 21c, they are along being approximately perpendicular to the relative shorter side corresponding extension of the direction of mainboard 21a from this mainboard 21a.Lid 22 is roughly the same with the shape of lid 21, and comprises mainboard 22a and the side plate 22b and the 22c that extend at a predetermined angle from the periphery of mainboard 22a.
As can be seen from Fig. 15, each exterior part 211 and 221 with flat grain surface has the textured pattern that wood-fibred does not extend along consistent direction.On the other hand, has in the inner part 212 and 222 on straight grain surface direction of wooden fibers L at each
212And L
222Be roughly parallel to the vertical of lid 21 and 22 respectively.When exterior part has the flat grain surface, promptly has the non-consistent wood-fibred pattern that extends, and inner part has the straight grain surface, promptly has the consistent wood-fibred pattern that extends, and this exterior part and this inner part are stacked to form lid 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 makes image-generating unit 5 opening 23 that exposes and the opening 24 that is used to install photoflash 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 display unit 8 is exposed; this display unit is by realizations such as LCD, plasma display, OLED displays, and is provided with the guard member of being made by glass etc. on opening 27, is used to protect display unit 8.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 is bonded together, thereby notch 251 and 252 is faced formation opening 25 mutually, thereby and notch 261 and 262 mutual facing form opening 26.Opening 25 exposes shutter release button 7, and opening 26 exposes the connection device that is used to be connected to such as the external equipment of personal computer.Can be opening 26 cover cap is set, be used to protect untapped connection device.
Then, the method that lid is processed into said structure will be described in detail.At first, cut out ligneous piece, make the ligneous piece that cuts out go out to treat the amount that reduces by compression than finished parts is big as the material of lid 21 and 22 from log.Figure 16 is a key diagram of representing that schematically the ligneous piece as the material that is used for lid 21 and 22 is shaped from unpressed log 50.Ligneous piece 53 as the material that is used for exterior part 211 or 221 is the plane sheets that cut out from log 50, makes the direction of wooden fibers L that vertically is roughly parallel to log 50 of ligneous piece 53.Therefore, obtain to have the ligneous piece 53 (referring to Figure 17) on flat grain surface.
On the other hand, cut out from log 50, make the direction of wooden fibers L that vertically is roughly parallel to log 50 of ligneous piece 54, and have the straight grain surface as the ligneous piece 54 of the material of inner part 212 or 222.Ligneous piece 54 has the structure identical with the ligneous piece 51 shown in Fig. 5. Ligneous piece 53 and 54 has the identical thickness of being represented by R.Ligneous piece 53 is longer than ligneous piece 54 in the vertical.
Then, the ligneous piece 53 and 54 that cuts out is compressed (compression is handled).In compression is handled, placing the scheduled time under with the water vapor of ligneous piece 53 and 54 before the compression at HTHP.Afterwards, make excessive suction and softening scheduled separately two metal die clampings and the compression of ligneous piece 53 and 54.

Figure 18 schematically illustrates key diagram how to carry out adhesion process, wherein will handle the exterior part 211 and the inner part 212 that form and be dried by compression and stack also bonding.Below, will the adhesion process of lid 21 be described.Lid 22 also is subjected to identical adhesion process.
In adhesion process, an amount of adhesive is coated at least one in the outer surface of the inner surface of exterior part 211 and inner part 212, thereby makes exterior part 211 and inner part 212 bonding and form the original form of lid 21.In adhesion process, similar with first embodiment, can adopt suitable anchor clamps with correct bonding exterior part 211 and inner part 212.
Afterwards, in the original form of the lid 21 that forms like this, forming under the situation of opening, notch etc., finishing the lid 21 of the part of the shell 2 that constitutes digital camera 200 in the pre-position by cutting or punching press.The thickness of finished product lid 21 is approximately 30% to 50% of the gross thickness 2R of two ligneous pieces before compression.
Therefore, the second embodiment of the present invention has realized the advantage identical with first embodiment.According to aforesaid second embodiment, compress two wooden respectively, bonding afterwards two stacked compressed wood film-makings.Therefore, in handling, compression can make ligneous piece's attenuation so that its shaping.
In addition, same according to second embodiment, the layer alternately laminated (referring to Figure 13) that layer that intensity is higher and intensity are lower, thus the compressed wood article of the output with high strength and high tenacity can be provided.
Also have, according to second embodiment, the textured pattern that constitutes the exterior part of lid and inner part is made into inequality, thereby makes the direction of wooden fibers in exterior part and the inner part intersected with each other, replenishes the intensity of the deficiency in each other the weak location with direction surfacewise.Therefore, the intensity along surface direction that can eliminate ligneous piece is inhomogeneous, thereby can be provided at the lid that all has proper strength on its whole zone.
Therefore, in a second embodiment, adopt ligneous piece respectively and have the ligneous piece on straight grain surface as exterior part and inner part with flat grain surface.This selection of textured pattern is preferred in the following areas.At first, though the flat grain pattern is so sorted out, it all demonstrates different patterns in each ligneous piece.When adopting flat grain ligneous piece as the exterior part of product, this textured pattern can be used as the part of product design, thereby each product can both demonstrate more showy and unique personal feature.Secondly, straight grain ligneous piece trends towards having lower anisotropy and its direction of wooden fibers unanimity.Therefore, this ligneous piece is firm with respect to the power that applies along the direction vertical with direction of wooden fibers, and deals with easily along the machine direction bending.Therefore, the combination of flat grain ligneous piece and straight grain ligneous piece makes and can make the compressed wood article with described two kinds of advantages.
Alternatively, can adopt have end grain (end grain) surface ligneous piece as exterior part, the ligneous piece that perhaps can adopt the textured pattern (for example middle textured pattern of straight grain and flat grain) with non-straight grain pattern is as inner part.
In a second embodiment, similar to first embodiment, compressed wood article can be by making more than two ligneous piece.As mentioned above, flat grain ligneous piece and end grain ligneous piece are unique in its design.When for example adopting flat grain ligneous piece or end grain ligneous piece as exterior part, adopt two straight grain ligneous pieces as inner part and all be stacked in them on the exterior part simultaneously, when making that the direction of wooden fibers of two straight grain ligneous pieces is roughly mutually vertical and carrying out adhesion process, the compressed wood article of generation can have suitable intensity and excellent design.Here, when when log is made, flat grain ligneous piece or end grain ligneous piece can be all thinner than in other two straight grain ligneous pieces each.

Exterior part 311,321 and inner part 312,322 all are straight grain ligneous piece.Among these ligneous pieces, the direction of wooden fibers of exterior part 311 and inner part 312 is roughly parallel to the vertical of lid 31, and the texture 50G of exterior part 311 that stacks and inner part 312 is roughly the same.In addition, the direction of wooden fibers of exterior part 321 and inner part 322 is roughly parallel to the vertical of lid 32, and the texture 50G of exterior part 321 that stacks and inner part 322 is roughly the same.
The mainboard 31a of lid 31 comprises makes image-generating unit 5 opening 33 that exposes and the opening 34 that is used to install photoflash 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 display unit 8 is exposed; this display unit is by realizations such as LCD, plasma display, OLED displays, and the guard member of being made by glass etc. is installed on opening 37, is used to protect display unit 8.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 is bonded together, thereby notch 351 and 352 is faced formation opening 35 mutually, thereby and notch 361 and 362 mutual facing form opening 36.Opening 35 exposes shutter release button 7, and opening 36 exposes the connection device that is used to be connected to such as the external equipment of personal computer.Can be opening 36 cover cap is set, be used to protect untapped connection device.
Then, the method that lid is processed into said structure will be described in detail.At first, cut out as the ligneous piece that is used for the material of lid 31 and 32, make the ligneous piece that cuts out than the big amount that goes out to treat by the compression minimizing of finished parts from unpressed log 50.
Figure 21 is a key diagram of representing that schematically the ligneous piece as the material that is used for lid 31 and 32 is shaped from unpressed log 50.Ligneous piece 55 as the material that is used for exterior part 311 or 321 is the plane sheets that cut out from log 50, makes the direction of wooden fibers L that vertically is roughly parallel to log 50 of ligneous piece 55, thereby presents the straight grain pattern.Ligneous piece 56 as the material that is used for inner part 312 or 322 is the plane sheets that cut out from log 50, makes the direction of wooden fibers L that vertically is roughly parallel to log 50 of this ligneous piece, thereby presents the straight grain pattern.Ligneous piece 55 and 56 has the identical thickness of being represented by R.Ligneous piece 55 is longer than ligneous piece 56 in the vertical.
Then, the ligneous piece 55 and 56 that cuts out is compressed (compression is handled).In compression is handled, placing the scheduled time under with the water vapor of ligneous piece 55 and 56 before the compression at HTHP.Afterwards, make excessive suction and softening scheduled separately two metal die clampings and the compression of ligneous piece 55 and 56.
Handle by compression, ligneous piece 55 and 56 is deformed into has roughly consistent thickness r respectively on their whole zone
5(＜R) and r
6(＜R).In the 3rd embodiment, compress and handle so that the thickness r of ligneous piece 55
5Equal the thickness r of ligneous piece 56
6The compression ratio C of ligneous piece 55
5=(R-r
5The compression ratio C of)/R and ligneous piece 56
6=(R-r
6)/R equates and all is approximately 0.5 to 0.7.When ligneous piece 55 and 56 forms unnecessary portions because compression is handled on its periphery, remove such part and on the surface that generates, carry out suitable processing by cutting.
Figure 22 schematically illustrates key diagram how to carry out adhesion process, wherein will handle the exterior part 311 and the inner part 312 that form by the compression that separates and stack and make them bonding mutually.Below, will the adhesion process of lid 31 be described.Lid 32 also is subjected to identical adhesion process.
In adhesion process, an amount of adhesive is coated at least one in the outer surface of the inner surface of exterior part 311 and inner part 312, thereby makes exterior part 311 and inner part 312 bonding to form the original forms of lid 31.In adhesion process, similar to first embodiment, can adopt suitable anchor clamps with correct bonding exterior part 311 and inner part 312.
Afterwards, in the original form of the lid 31 that forms like this, forming under the situation of opening, notch etc., finishing the lid 31 of the part of the shell 3 that constitutes digital camera 300 in the pre-position by cutting or punching press.The thickness of finished product lid 31 is approximately from 30% to 50% of the gross thickness 2R of two ligneous pieces that unpressed log 50 cuts out.
In the 3rd embodiment, the textured pattern of exterior part and inner part is basic identical usually after adhesion process.Like this, owing to external force apply or the pucker ﹠ bloat of the shell 3 that the variation of temperature or humidity causes roughly is identical in the exterior part that is bonded with each other and inner part.Therefore, the inner accumulation stress of parts and inner part outside.Therefore, product can have specific advantage, even that is: applying under the situation that external force or temperature or humidity changes, also can not produce strain.
In addition, when the textured pattern of exterior part and inner part was roughly the same, the product of generation can have and the identical characteristic of being made by a ligneous piece of identical shaped compressed wood article.On the other hand, though direction of wooden fibers in the exterior part and the direction of wooden fibers almost parallel in the inner part, exterior part and the inner part textured pattern after being bonded together also mates not exclusively mutually.Therefore, can have less intensity anisotropy, and to compare its intensity more consistent with the compressed wood article of being made by a ligneous piece as in these embodiments the compressed wood article of making by a plurality of parts.
In the 3rd embodiment, the ligneous piece of employing must not be a straight grain ligneous piece, as long as the textured pattern of exterior part and inner part is roughly the same.Interchangeable is can adopt flat grain ligneous piece, end grain ligneous piece or have flat grain and the ligneous piece of the middle textured pattern of straight grain.
According to aforesaid the 3rd embodiment, compress two wooden respectively, bonding afterwards two stacked wooden.Therefore, in handling, compression can make ligneous piece's attenuation so that its shaping.
In addition, according to the 3rd embodiment, the layer alternately stacked (referring to Figure 13) that layer that intensity is higher and intensity are lower, thus the compressed wood article of the output with high strength and high tenacity can be provided.
Also have, according to the 3rd embodiment, exterior part and inner part are stacked to become to make their textured pattern to mate substantially and in adhesion process they is fixed.Therefore, two processed parts expand in essentially identical mode and shrink, thereby prevent the accumulation of internal stress.Therefore, even, also be not easy to produce strain applying under the situation that external force or temperature or humidity changes.
In addition, according to the 3rd embodiment, though the coupling of textured pattern makes product have the advantage identical with the product of being made by a ligneous piece, the textured pattern of overlay part also not exclusively mates.Therefore, compare, can make the anisotropy of intensity less, thereby the bulk strength of product can be consistent more with the compressed wood article of making by a ligneous piece.
The 4th embodiment
Figure 23 is a key diagram how to handle ligneous piece in the adhesion process that schematically is illustrated in according to the Wood treatment method of fourth embodiment of the invention.As shown in figure 23, the exterior part 411 and the inner part 412 that have carried out the compression processing with identical compression ratio are carried out adhesion process, and between them, be inserted with reinforcement 413.Described compression processing is identical with above-mentioned first to the 3rd embodiment's, in this compression is handled, will be compressed into exterior part 411 and inner part 412 from the plane ligneous piece that log cuts out respectively.
In Figure 23, owing to can not consider that according to the Wood treatment method of the 4th embodiment textured pattern or direction of wooden fibers in exterior part 411 and the inner part 412 are used, therefore not be clearly shown that the textured pattern and the direction of wooden fibers of exterior part 411 and inner part 412.
For example, if exterior part 411 and inner part 412 are straight grain ligneous pieces similar to the exterior part 111 of first embodiment and inner part 112, then the direction of wooden fibers of exterior part 411 is arranged to be roughly parallel to the vertical of lid 41, and the direction of wooden fibers of inner part 412 is arranged to be roughly parallel to the horizontal of lid 41.Therefore, if reinforcement 413 is arranged between exterior part 411 and the inner part 412, make the machine direction in this reinforcement all become miter angle with the direction of wooden fibers of exterior part 411 and inner part 412, then reinforcement 413 can be used for the product strengthening generating, and wherein exterior part 411 is stacked along the relative more weak direction of intensity with inner part 412.
Figure 24 is the stereogram of the structure of the lid 41 finished by adhesion process, and Figure 25 is the profile of lid 41 along the line D-D of Figure 24.As Figure 24 and shown in Figure 25, be arranged in reinforcement 413 between exterior part 411 and the inner part 412 and partly nip in the surface of exterior part 411 and inner part 412.But reinforcement 413 is mainly formed by the composition that comprises in the timber, thereby have high affinity with timber.Therefore, waiting by cutting and not damaging under the situation of wood-fibred, reinforcement 413 is fixed on the surface of ligneous piece with fit-state (conforming state).
In addition, applying under the situation that external force or temperature or humidity changes, reinforcement 413 is out of shape with the distortion of lid 41, thereby prevents lid 41 excessive deformations.This is because reinforcement 413 is mainly formed by the composition that comprises in the timber, thereby the Young's modulus of this reinforcement 413, thermal coefficient of expansion and hygral expansion coefficient are respectively near Young's modulus, thermal coefficient of expansion and the hygral expansion coefficient of lid 41.
Here, the direction of wooden fibers of reinforcement 413 might not be wanted consistent the alignment, but can be unordered.Also alternatively, reinforcement 413 can be formed by the fiber that is woven into net.In addition, the length of each fiber must not be consistent, and reinforcement 413 can be formed by as thin as a wafer fabric (being made by silk or fiber crops), supatex fabric etc.
The material that is used for reinforcement 413 is not limited to comprise the material of wood fiber component.For example, can application of carbon fibres as reinforcement 413, and can adopt the suitable material that posts predetermined fabric as reinforcement 413.Also alternatively, reinforcement 413 can be formed by sheet metal or wire netting.
The lid 41 that forms as mentioned above is with to be similar to another lid (not shown) that lid 41 forms combined and constitute the shell of electronic equipment.(for example be used for electronic equipment, digital camera) this shell except having reinforcement 413, its structure and assemble method etc. respectively with according to identical (referring to Fig. 1 to Fig. 3) such as the structure of the shell that is used for digital camera 100 1 of first embodiment and assemble methods.
According to the aforesaid fourth embodiment of the present invention, can easily form compressed wood article, and direction provides suitable intensity on its whole zone surfacewise.
In addition, according to the 4th embodiment, exterior part by being arranged in lid (compressed wood article) and the reinforcement between the inner part can further improve the intensity of lid.
Specifically, comprise in use under the situation of reinforcement of wood fiber component, the shrinkage factor of reinforcement and the shrinkage factor of ligneous piece are roughly the same.Therefore, to have the quality of high affinity and product material can be uniform for this reinforcement and timber.In addition, the reinforcement that comprises wood fiber component is not cut in the wood-fibred of ligneous piece self, thereby does not have further to have improved the intensity as the lid of compressed wood article under the situation of decline in the intensity of ligneous piece self.
Here, reinforcement can be applied to one or two in the inner surface of the outer surface of exterior part and inner part.When on the outer surface that reinforcement is arranged on exterior part, reinforcement is as the part of product design, thereby further improved unique quality of product, and helps to improve the intensity of compressed wood article.On the other hand, when on the inner surface that reinforcement is arranged on inner part, the intensity of compressed wood article can be improved, and to its outward appearance without any influence.
When adopting the ligneous piece that surpasses two to make compressed wood article, can between at least one pair of adjacent ligneous piece, arrange reinforcement.
Other embodiment
Though more than described first to fourth embodiment as exemplary embodiment of the present in detail, the present invention is not limited to the foregoing description.Other embodiment of various details.
(1) can be between the exterior part of lid and inner part the arranging electronic function element.For example, arrange the earthed circuit plate outside between parts and the inner part, so that earthed circuit can be connected to the electronic component that is contained in the shell.So the space that is used for earthed circuit that may be arranged on enclosure usually is not necessary, therefore can save the space.In addition, between parts and the inner part sheet metal can be set outside.This sheet metal is also avoided electromagnetic wave as shielding material with the protection product except as the reinforcement.And, the sheet material that wherein is built-in with IC chip or various installation elements, flexible base, board etc. can be set between parts and the inner part outside.Therefore, can in the electronic equipment of making, realize various functions.
When lid when forming more than two ligneous piece, can arrange reinforcement and electric function element in multiple position.These elements can be according to the purposes of lid and are arranged with compound mode.
(2) Figure 26 is the profile of the structure of the lid made by the compressed wood article of exterior part with different-thickness and inner part.Compression ratio for exterior part 451 and inner part 452 is identical.As shown in figure 26, lid 45 has exterior part 451, the thickness h of this exterior part
1Thickness h less than inner part 452
2(h
1＜h
2).Because exterior part 451 is thinner relatively, therefore can adopt easy crackle and the ligneous piece that is difficult to be shaped as material.For example, can adopt flat grain ligneous piece or end grain ligneous piece to be used for exterior part 451.Therefore, by utilizing than thin ligneous piece, the damage of being simplified and preventing generation such as crackle in ligneous piece is handled in compression.
On the other hand, by utilization have higher-strength such as the ligneous piece of straight grain ligneous piece as inner part, the bulk strength of lid 45 can improve the amount that thickness increased of the parts with higher-strength, but the integral thickness of lid itself does not change.When tabular ligneous piece is subjected to processing such as bending, and inner part and the deformation extent of exterior part in compression is handled are not simultaneously, and it is thinner that the parts with high deformation degree can be arranged to the yielding parts of specific volume.
(3) thickness by regulating ligneous piece and in compression is handled the shape of used metal die, can change the compression ratio that is used for exterior part and inner part at each parts.The tone of ligneous piece after compression of being made by the timber of identical type changes according to compression ratio.More particularly, compression ratio is high more, and the carbonization of ligneous piece just impels surface color to deepen more.In addition, the surface smoothness and the glossiness and more anti-dirty that have raising with the compressed ligneous piece of higher relatively compression ratio.
On the contrary, compressed ligneous piece is softer with relatively low compression ratio, but compares with the ligneous piece with relative higher compression ratio, and surface color changes less.In addition, keep more fine with the compressed ligneous piece of relatively low compression ratio as the texture and the sense of touch of timber.The compression ratio that according to the design or the feature of product to be made ligneous piece is set if consider These characteristics then can produce the compressed wood article of the uniqueness with various tones.
For example, owing to be difficult to by formation end grain ligneous pieces such as bendings, thereby the compression ratio that is used for end grain ligneous piece can be provided with lower, and owing to straight grain ligneous piece forms easily, thereby the compression ratio that is used for straight grain ligneous piece can be provided with higher.Like this, can easily form compressed wood article by these ligneous pieces stacked and compressed together.Therefore, by combination, can guarantee suitable intensity and the product of the various outward appearances of various color harmonies is provided with the different compressed ligneous pieces of compression ratio.
In being lower than the scope of limit compression ratio of ligneous piece, the compression ratio of ligneous piece is set to when enough high, this compression not only brings the change of tone, but also causing the carbonization of ligneous piece by burning of heated metal die, this makes wooden materials become conductor as electromagnetic shielding again.Therefore, thereby when utilize according to Wood treatment method according to the present invention make compressed wood article with this compressed wood article when being used for the shell of electronic equipment, preferably utilize high compression rate that a ligneous piece is become conductor, and another ligneous piece is not carbonized and remains insulator, the ligneous piece that then these is had different characteristic stacks to form shell.With regard to the manufacturing of this compressed wood article, at least one in finished product in the surface of the surface of opposed facing exterior part and inner part can be carbonized in compression is handled.
(4) in the superincumbent description, suppose that all ligneous pieces are all made by the timber of identical type.But the kind of timber can be different because of the difference of parts.For example, when the lid that is used for electronic equipment is formed by two ligneous pieces that stack, preferably can adopt the good especially timber kind of outward appearance as exterior part improving design characteristics, and, therefore adopt firm timber kind as inner part owing to pay close attention to the higher-strength of inner part.When the combination of the ligneous piece of being made by different types of timber is utilized well and is handled, the compressed wood article of generation can have only adopt from ligneous piece that a kind of timber is made the intensity and the outward appearance that can not obtain.
Here, can regulate the thickness and the compression ratio of each parts according in the same manner as described above as the intractability of the timber of exterior part and inner part.
(5) ligneous piece can cut into predetermined 3D shape from log.Opening or notch can when cutting out ligneous piece, log formed.Alternatively, this opening or notch can form by cutting or punching press after cutting out ligneous piece from log.
(6) compressed wood article that forms by Wood treatment method according to the embodiment of the invention, can be used as sheathing material and be applied to electronic equipment except digital camera, for example: such as the mobile terminals of portable phone, personal handyphone system (PHS) or PDA(Personal Digital Assistant), be equipped with such as the audio recording medium of MD, CD or tape portable audio device with output audio, the IC phonographic recorder, portable television, portable radio, the remote controller of various household electrical appliance and DV.In addition, can be used for purposes except the shell that is used for electronic equipment according to the compressed wood article of described embodiment.
The embodiment that can realize by the appropriate combination of above-mentioned first to fourth embodiment and other listed embodiment of (1) to (6) falls within the scope of the invention.Therefore, under situation about not deviating from, can make various modifications by the spirit or scope of claims and the general idea of the present invention that equivalent limited thereof.
